Medieval Ireland the Coming of the Normans, 1167â€1185

By the 12th century, Ireland was divided politically into a shifting hierarchy of petty kingdoms and over-kingdoms. Power was concentrated into the hands of a few regional dynasties contending against each other for control of the whole island. The Northern Ui Neill ruled much of what is now Ulster. Their kinsmen, the Southern Ui Neill, were Kings of Brega (Meath). The kingship of Leinster was held by the dynamic Ui Cheinnselaigh dynasty. A new kingdom rose between Leinster and Munster, Osraige, ruled by the family of Mac Giolla Phadraig. Munster was nominally controlled by the Mac Cartaig, who were however in reality often subject to the Ui Bhriain of Thomond. North of Thomond, Connacht's supreme rulers were the Ui Chonchubhair. After losing the protection of Tyrone Chief, Muirchertach MacLochlainn, High King of Ireland, who died in 1166, Dermot MacMurrough (Irish Diarmait Mac Murchada) , was forcibly exiled by a confederation of Irish forces under the new High King, Rory O'Connor. Diarmait fled first to Bristol and then to Normandy. He sought and obtained permission from Henry II of England to use the latter's subjects to regain his kingdom. By 1167 MacMurrough had obtained the services of Maurice Fitz Gerald and later persuaded Rhys ap Gruffydd Prince of Deheubarth to release Maurice's half-brother Robert Fitz-Stephen from captivity to take part in the expedition. Most importantly he obtained the support of the Earl of Pembroke Richard de Clare, known as Strongbow. The first Norman knight to land in Ireland was Richard fitz Godbert de Roche in 1167, but it was not until 1169 that the main forces of Normans, Welsh and Flemings landed in Wexford. Within a short time Leinster was regained, Waterford and Dublin were under Diarmait's control, and he had Strongbow as a son-in-law, and named him as heir to his kingdom. This latter development caused consternation to King Henry II of England, who feared the establishment of a rival Norman state in Ireland. Accordingly, he resolved to visit Leinster to establish his authority. The Papal Bull and Henry's invasion: Pope Adrian IV (the first English Pope, in one of his earliest acts) had already issued a Papal Bull in 1155, giving Henry authority to invade Ireland as a means of curbing ecclesiastical orruption and abuses. Little contemporary use, however, was made of the Bull Laudabiliter since its text enforced papal suzerainty not only over the island of Ireland but of all islands off of the European coast, including England, in virtue of the Constantinian donation. The relevant text reads: â€Å"There is indeed no doubt, as thy Highness doth also acknowledge, that Ireland and all o ther islands which Christ the Sun of Righteousness has illumined, and which have received the doctrines of the Christian faith, belong to the jurisdiction of St. Peter and of the holy Roman Church†. References to Laudabiliter become more frequent in the later Tudor period when the researches of the renaissance humanist scholars cast doubt on the historicity of the Donation of Constantine. Henry landed with a large fleet at Waterford in 1171, becoming the first King of England to set foot on Irish soil. Both Waterford and Dublin were proclaimed Royal Cities. Adrian's successor, Pope Alexander III ratified the grant of Irish lands to Henry in 1172. Henry awarded his Irish territories to his younger son John with the title Dominus Hiberniae (â€Å"Lord of Ireland†). When John unexpectedly succeeded his brother as King John, the â€Å"Kingdom of Ireland† fell directly under the English Crown. Henry was happily acknowledged by most of the Irish Kings, who saw in him a chance to curb the expansion of both Leinster and the Hiberno-Normans. This led to the ratification of the Treaty of Windsor (1175) between Henry and Ruaidhri. However, with both Diarmuid and Strongbow dead (in 1171 and 1176), Henry back in England and Ruaidhri unable to curb his nominal vassals, within two years it was not worth the vellum it was inscribed upon. John de Courcy invaded and gained much of east Ulster in 1177, Raymond le Gros had already captured Limerick and much of north Munster, while the other Norman families such as Prendergast, fitz Stephen, fitz Gerald, fitz Henry and le Poer were actively carving out virtual kingdoms for themselves.

Drivers Education Essay

Both SADD and MADD have had various positive impacts to the society supportive implications to the well worth of the society in correspondence to the influence they have to our society. The Original meaning of SADD was â€Å" Students Against Drunk Driving† but have changed to mean â€Å"Students Against Destructive Decisions†. Robert Anastas founded SADD in 1981 in company of other student in the wayland high school in Massachusetts. It started after two hockey players from Wayland high school were killed separately in the July of 1981. These incidences led towards working together of Anastas and his fellow mates. The basic core of SADD was to provide an ultimate contract for human life. It was and is the only student national organization, which deals with impaired driving, violence emanating from drug use, underage drinking, impaired driving and a broad array of activities that affects the lives of teenagers. (http://chicagoathome. com/dct/54/id/3528/mid/2347/This-Year–S-A-D-D–Conference. aspx) The original goal of SADD was in helping the young people from drinking through saying â€Å"No† to driving while drunk. However, such former mission has seen an expansion to capture the expanding problems that seems to face the adolescence in the current times. This is what provided for the change in the name from the former meaning to what is held currently. With this mission, students have continued to communicate with the adults within their reach about the role and implication of positively attitude of peer pressure, use of role models as well as a binary of other substantial strategies that can help to say â€Å"No† towards any activity of driving while drunk. This has seen SADD enjoy the sovereignty of being an organization modeled towards peer leadership. The basic ideology behind SADD is to prevent the effect of the idea behind underage drinking as well as drug abuse. It seeks to focus its attention towards modeling potential life that would not be threatened by the consequences of various destructive youth decisions. According to SADD, destructive decision include engaging in the domain of sexual activities that would lead to disease transmission, violence, smoking, failure of using safety belts as well as suicide commission. Consequently, SADD has its basic mission of providing students with the most adequate preventive and intervention protocol that would perhaps encourage any activity of drunk driving, destructive decisions, drug abuse and underage drinking. Across the years since its conception, SADD has even incorporated various activities that help to spread its message to a broad domain of the societal population. They have used ‘pre-prom’ assemblies that have been held in various districts in helping to provide a better scope of awareness to the societal domain about the dangers allied to driving while drunk. Across the years, SADD have invited people towards participating in various conferences that aim at working together in addressing the aspect of driving and drinking. It has in the recent years expanded its horizons to incorporate various virtuous topics that are not related to drinking. This includes eating disorders, teenage pregnancies, driving practices that are not safe and broad-spectrum of social issues affecting the teens. Their focus has been addressing the long and short-term implications of various destructive decisions taken by the youth. Like SADD, MADD has its foundation of addressing various aspects on driving and drinking. MADD stands for â€Å"Mothers Against Drunk Driving†. The foundation of MADD was seen in 1980 by a group of women from California. This was after a driver hit a 13 year-old-girl before running away. The same driver had recently been out of the jail after being convicted of yet another crime of hitting accident. Historically, he had formerly committed other several accidents. However, since the 1980 this organization (MADD) has seen a massive expansion and growth. To formalize its activities, MADD provided an official position of its president who is elected and remains in the office for a specific time period. (http://chicagoathome. com/dct/54/id/3528/mid/2347/This-Year–S-A-D-D–Conference. aspx) Currently, MADD is an organization operating at the grass root level and compounds around 600 chapters across the world. However, it does not deliver any campaign against alcoholism as thought by many people. However, it has its mission of stopping drunk driving, preventing underage drinking, and supporting the pertinent victims who commit the crime of drunk driving. It has its focus on looking towards the most appropriate and effective solutions, which can be provided towards problems allied to underage drinking and drunk driving. Elsewhere, it has its motive towards providing support for those already salvaged by these crimes through giving moral support and counseling. (Sarah, 1995, 79) Considerably therefore, both the SADD and the MADD are social organizations that are aimed at improving and promoting the state of living held by young people. At a closer range, SADD is a students organization with its benchmark towards helping students against the subjective influence of peer pressure influence. It has its motive of striking a balance between the proximities of education that is combined with a positive peer pressure influence. Through this motive, SADD mission believes that there will be an autonomous life saving. Like SADD, MADD has its mission statement rooted in the well being of the society through postulating an imaginary that promotes their livelihood. It aims at improving and sustaining the status of their lives by addressing various problems that affect the social life phenomena of the youth. (Gerald, 1991, 92) Generally, both the SADD and MADD have almost the same operational framework in their regions of support. By and large, the two organizations have seen it worth of using social conferences that help to address the broad outlay social problems and crimes that affect the youth. Generally, use of conferences has been a motivating campaign that has seen the process of counseling produce adequate results and benefits. Elsewhere, direct conduct of students with the other members of the society has been an adequate tool towards describing how they operate in the regions. Students and the youth in general elaborates and campaign to the society through oral persuasion to address the impacts and the consequences of different crimes to the other members of the society. Notedly also, a full pledge of campaign has been achieved through posters, signs, signals, artistic works and other stylistic devices. (http://chicagoathome. com/dct/54/id/3528/mid/2347/This-Year–S-A-D-D–Conference.aspx) Generally, these organizations can highly be echoed of their response effectiveness towards meeting their goals. Since their primary mission has been to disseminate awareness on how the young people are to provide fruitful benefits. Many youths and students have incorporated the teachings of the organization giving them fruitful benefits towards avoiding the negative impacts of such crimes to their lives and the general society. Notedly, there has been a more conscious awareness across the board by students in knowing the relative impact of driving while drunk. The social imaginary of the youth have also been positively modeled by the lessons learnt from their teachings. Work cited Gerald, D.

Automating computer usual processes Essay Example for Free

Automating computer usual processes Essay Nowadays, almost all kinds of establishments are relying on computers for automating their usual processes. Most of the manual systems in offices are replaced by the automated systems which use computer technology. Moreover, computers have also diminished the total manual works and the effectiveness of employees has also increased because of the dependence of establishments on computer technology. It helps also to perform the routine business tasks much quicker compared to the manual way of doing things. Computer nowadays is no longer considered a luxury but rather a necessity with the emergence of information technology 1 â€Å"We are in the so-called information age, and every transaction at every phase of the establishments depends on modern computing. † As observed, there are already many manual systems that are being replaced by the computerized ones. Some of these are the payroll, sales and monitoring, point of sale, enrollment, grading, library, and other related systems.. Integration with the people in the society is in demand for progress. The relation field of Information Technology concerns the use of computer-based information system to convert, process, protect, share, store, transmits and retrieve information. Technologies have brought us more advances on personal computer, to build new industries and change the lifestyle of each individual. These advances became more powerful and more productive for simultaneous growth in society and industries. Using Internet is one of the medium of today’s communication, people easily connect in the current events in their community and even outside their places and acquire necessary information in just a short period of time. 2As the saying goes, â€Å"Nothing is permanent than change† so as with Information Technology. This field will continue to prosper and continue to help change lives by improving it. Although most people, especially in the Philippines still prefer the old ways or manual transactions, the future Filipino generations will eventually embrace ch ange and not only that, but also be the one to provide change through the future students and graduates that will courageously take this field. Every bit of information is now considered as a powerful tool hence it should be used and managed with the utmost caution. This mere reason prompts many establishments to produce their own system  that will protect information. The Bicol Consortium for Health Research and Development (BCHRD) was established to address the existing health condition in the Bicol region. It is a coordinating system involving various institutions in the region with interest in health research. The BCHRD was created upon the partnership with Philippine National Health Research System (PNHRS), Regional Development Council (RDC) with the member institutions of : Department of Health (DOH) ,Bicol Regional and Training And Teaching Hospital(BRTTH), Commision on Higher Education (CHED) , Bicol University (BU), Catanduanes State University (CSU), University of Saint Anthony, Ago Medical and Educational Center (AMEC), Atedeo de Naga, University of Nueva Caseres, Camarines Sur Polytechnic Colleges, Aquinas Univ ersity of Legazpi (AUl), Department of Science and Technology (DOST), Bicol Medical Center, Partido State University (PSU) . The existing health condition in the region necessities the establishment of a strong health research and development (R&D) coordinating system involving various institution in the region with interest in health research. Putting them together to work on consortium arrangement will promote complementation, thereby increase the synergy despite limited resources for R&D undertakings. The Bicol Consortium for Health Research and Development (BCHRD) was therefore established to address the afore mentioned concerns. The primarily goal and objective of BCHRD is to institute/strengthen the system collaboration in Bicol to develop and enhance the capacity of research institution within the region which have interest and engage in health related researches, as a strategy to improve the health condition of Bicolanos Specifically the consortium aims to : (a) Undertake and/or spearhead health related Research and Development (R&D) activities; (b) Establish a collaborative system for effective sh aring and utilization of physical, financial and manpower resources among member-institution as well encourage the active involvement of non-members that will fave the way for expanding the membership of consortium; (c) Promote an effective collaboration and harmonious working relationship between among member-institutions in the conduct of researches in health, nutrition related fields; (d) Encourage, generate and provide funds for health –related researches in accordance with the health and nutrition priority  areas/sectors indicated in the plans of the Regional Development Council (RDC) and the Philippine National Health Research System (PNHRS); (e) Develop the capability in manpower, facilities and other infrastructure for health and nutrition and other related researches; (f) Effectively promote the proper utilization of health research findings; (g) Serve as clearing house for all health related researches; (h) Establish linkages/network within and outside the region ; and (i) Institute a mechanism and implement strategies for a sustained visibility of the consortium and ensure a long-term viability of the consortium. Monitoring system is not just used in the field of industry; it has also a very significant role in improving the quality of education in the country (Philippines). Once this technological approach is implemented a full assurance that the aimed quality of educational system will be able to reach its peak of being more organized and well improved system In terms of paper works, these two types of management system can easily manage the projects through having an Proposal monitoring system. Archiving system refers to the process of moving data through an automated storage device that helps the people to access the data easily. Before, an archival record was identified with manuscripts or with written records. Years passed by, archival record refers to recorded information, specifically in paper-based transforming it to automated form method. Implementing an archiving system of records can do task of organizing, monitoring and easy generation of reports. On the other hand, all the Research proposal that are pending, denied or approve must be monitored in order to ease the different operations and functions of organizations. In this study, monitoring system for the research proposal of the institution is the most needed to work to. This system updates the current status of the research project. In addition, monitoring system has a significant role in improving the quality of the implemented projects to be able to reach its goal. Because of its function, they are having problems in a certain field. They seem to have problems in the management of projects from time to time. In addition, the increasing burden of creating and maintaining the archive of projects. Their file storage is full of projects making it a burden when finding a needed project. This study aimed to create a system for the Bicol Consortium for  Health Research and Development. It covered the storing and updating of projects that are processed in the department and al so uploading projects in the system that can be retrieved easily. Statement of objective General Objectives This study aims to develop a research proposal and monitoring management system for the Bicol Consortium for Health Research and Development. Specific Objectives 1.) To create a system that will facilitate research proposal and monitor status for approval. 2.) To develop a monitoring system for all ongoing researches. 3.) To record all pending, approved and rejected proposals, and ongoing and completed research of the health proponent/researcher. 4.) To create a secure system for monitoring of research proposals and projects. 5.) To generate reports on the status of research projects and proposals. Check the requirements for filing a proposal Keep track of the status of the proposal Keep track of the research’s accomplishments and budgets Monitor progress of ongoing research This study is about Bicol Consortium for Health Research and Development. This will cover the checking of requirements the tracking and monitoring of the proposal. It has the overall planning, coordination, and control of a project from beginning to completion. The system records the detailed planning, proposed, on-going and finished projects in the department. Old  files were also scanned and be saved as pdf. The secretary, regional administrator, institution head and all the member of the health research were given privileged to view the system. The employees may ask the administrator of each section if they need files that were in the system. The head administrator provides admin accounts for each section head. The proposal monitoring management system has different sections for the storage of projects (proposed, on-going and finished projects) and it provided easy access to the projects’ status and tracks the finished projects that are archived. Old and new files are archived in this system. The date could only be searched, retrieved and printed. The archive could be searched by date, name etc. As for the proposal monitoring management system, it provided an automated monitoring and checking the status of ongoing research development. It has additional features, like the user is notified for the reminders of the agency; and the system is secured by providing administrator restrictions. On the other hand, the proposed system would not include other health researcher that are not member of the institutions that are part of BCHRD. The study only focused on the automation of storage of all projects that would be made and were done, monitoring its status among various sections of PDMO and provide an automated maintenance plan in monitoring, checking and repairing of items. Significance of the Study The result of the study will benefit the following: Bicol University. College of Science One of the four-fold functions of a university or any academic institution is research. This study will be another contribution to the research achievements of the university.

Team Working (Dynamics, Efficiency) Coursework Example | Topics and Well Written Essays - 2750 words

Team Working (Dynamics, Efficiency) - Coursework Example Team working is one of the prime aspects based on which organisational operations are conducted in a coordinated manner (European Foundation for the Improvement of Living and Working Conditions, 2007). These factors, as stated above, can be identified as quite relevant in the scenario, where a survey was conducted in the year 2013 by CIPD, unveiling that most of the employees in the UK are not offered with required development plans relating to team working skills by the management. This has been affecting staff performance within the organisation to a large extent. In addition, Cedar, which is a training consultancy operating in the UK, have disclosed that lack of support as well as training has been an important concern for affecting business productivity proving the arguments in CIPD report. Human resources are recognised as facing issues relating to support from management, complex inter-personal relationship, inadequate training and stressful working environment. In this respect, Cedar needs to adopt an effective leadership style based on which organisational performance and effectiveness can be enhanced. Thus, this report intends to approach the HR Director of Cedar, which w ill be critically analysing the issues to improve relationships and community spirits among teams. According to the study conducted by Tarricone & Luca (2002), teams are identified as an important consideration for any organisation to the delivery of required business unit with better efficiency. Teams are developed comprising members with desired competencies with the aim of ensuring that operations are conducted in a participative as well as coordinated manner (Tarricone & Luca, 2002). In a similar perspective, the article published by Pearson Education (2011) signified that teams refer to groups working with the intention of accomplishing certain common goals. Team members thus need to perform their operations in accordance with which, operations or activities are needed to

Religious Conflicts in Lebanon Essay Example | Topics and Well Written Essays - 2500 words

Religious Conflicts in Lebanon - Essay Example Moreover, there is conflict between the Sunni Muslim majority and the Shiite Muslim minority who been engaged in conflict for a long time and up to date, they are not at peace with each other. The Druze is another distinct fraction in Lebanon, they are also the minority in Lebanese society, and they have been into conflict with the Christians in the 1840s when the country was known as Mount Lebanon. Until today, there is tension between these religious groups as they are trying to build a stable democracy. It can be therefore noted that the chaos among religious groups in Lebanon is as a result of failure to establish a working power sharing system between these groups. This paper explores the religious conflict in Lebanon and it is organized in three sections. The first section presents sectarianism in Lebanon, followed by an analysis of the root of the conflict, identifying the actors and their interests. Lastly, the paper discusses possible solutions and consequences of different policy solutions. Mostly, the conflict in Lebanon is presented as a sectarian conflict, which involves the moderate Christians and the extremist Muslims (â€Å"Troubles a test†¦Ã¢â‚¬ ). Apart from religious differences between the Christians and the Muslims, there is also conflict within the Muslim community, between the Sunnis and the Shiites. The Muslim society was divided in Sunni and the Shiite because of the power struggle over succession (Tomass 714). The entire population including the Christians and Muslims speak Arabic language; however, sectarianism is a dominant socio-political reality in Lebanese society despite the features they have in common. Sectarianism is not a new in Lebanon, historical Lebanon also called Mount Lebanon used to be shared mainly by Druzes and the Maronites. They did not coexist in peace and harmony as they fought over land ownership and distribution of political power among other issues. But these two groups have coexisted in harmony until the

Childhood Obesity Assignment Example | Topics and Well Written Essays - 1000 words

Childhood Obesity - Assignment Example Obesity not only brings concern about health but it adds to the financial burden too. Obesity augments the health care costs. Estimates reveal that obesity accounts for approximately 10% of yearly medical expenses, increasing the obesity-associated medical costs to $147 billion in 2008. Obesity has reached an alarming position in USA, and two well distinguished categories have been demonstrated namely obese and extreme obese. Findings disclose that over one-third adults of United States adults were found to be obese during the year 2007–2008 (Flegal, 2010). According to The National Health and Nutrition Examination Survey (NHANES), the incidence of obesity in the United States could be estimated by means of data for height to weight ratio. The prevalence rate of obesity display that there was a steady increase in obesity equally in both the sexes belonging to all ages from 1976 -1980 to 1988-1994. On the other hand the trend in obesity augmentation between 1988-1994 and 1999-2 000 was significant in other ages except for the males belonging to the age between 40 to 59 years. While data analysis from 2001-2002 to 2003-2004 recommended escalating trends since 1999-2000 in males and not in females (Flegal, 2006).? Complications of Childhood Obesity Reports illustrate that around 7 million American children and teenagers are supposed to have elevated cholesterol concentrations. If LDL concentration rises at young age and when these kids grow as adults they are bound to have prominent LDL cholesterol intensities. Such overweight kids are likely to develop cardiovascular disease and diabetes, these diseases are otherwise associated with adults in their middle-age. A drastic rise in type 2 diabetes have been reported by pediatricians among the children and adolescents (Web: Child Obesity In America). Type 2 diabetes is associated with obesity. Reports reveal that almost 40% of the children are associated with this condition. Beside, the obese child also witnesse s physical health issues and social troubles. Morbidly obese children also suffer from emotional distress as a result they develop profuse eating habits. Observation reveals, obese children are delighted if they get eatables they wish for, thereby develop a tendency to eat constantly and still are not satisfied even after consuming a large full meal. Research reports highlight that that eating behavior of children have considerably altered over the past twenty years or so. Children are consuming greater percentage of their calories from junk food items and snacks, containing high proportion of fat, salt and sugar contributing to the obesity of the child (Ludwig & Ebbeling, 2001). Eating Habits The most favorite food items for kids of present epoch are ice creams, soda pop, hamburgers, cheeseburgers, pizza, French fries made of potatoes that is full of starch, milk shakes that are sugar syrups, chips, and candy bars. These food items are devoid of fibers and are rich in fats and chol esterol. Children find raw fruits and salads icky, as they are

Enhancing Correctional and Rehabilitation Results in Prision Research Paper

Enhancing Correctional and Rehabilitation Results in Prision - Research Paper Example In hindsight, in the 1970s, it was viewed that inmates who undergo rehabilitation are being left off easy and advocating such rehabilitations were seen as naivety. It is interesting to perceive that as society has been evolving through the years the propensity for criminal activities have also increased. But through the years, society changed its perception that indeed prisons must prepare the inmates in their re-entry to the community and not just serve as establishments to lock them up and serve their due time. Omar (2001) stated that â€Å"it is the general consensus that the fundamental objective of corrections is rehabilitation, whether such institutions are prisons, juvenile centers and other types of correctional institutions†. He added that the treatment process is directed towards the eventual return to the community of the inmates as law abiding and socially productive citizens. It is therefore the ultimate goal of correction facilities to reduce recidivism. Gaes et al. (1998) establishes that education, vocational training, and prison labor programs have decent effects on not only reducing criminal recidivism but also increasing positive behavior in prison. Although it was concluded that sex offender interventions proved to have been the most problematic. Treatments and rehabilitation practices should be adjusted and fitted to specific offender deficits. It is also worth noting that juvenile interventions yield better and stronger results than adult rehabilitations. Gaes et al. (1998) focused on four domains of adult intervention; 1) cognitive skills training, 2) intensive in-prison drug treatment, 3) educational instruction, vocational, and industrial training, and 4) sex-offender treatment. Based on meta-analyses, qualitative analyses, and reviews of component elements of successful programs, it was established that the most success in terms of criminal recidivism was achieved through emphasis on cognitive and skill building techniques. This approach is able to correct impulsivity by teaching consequential thinking, fatalistic thinking by practicing assessment of the role their thinking has affected their actions, antisocial behavior by teaching them skills for them to be prosocial, and social adjustments by teaching self-control techniques (Gaes et al., 1998) Aside from behavioral deficiencies, it is also an established fact that individuals under the influence of illegal drugs have greater tendency to commit crimes, and Gaes et al. (1998) notes that the level of crime is dramatically amplified by the use of drugs. It is of then a necessity in correctional facilities to incorporate drug rehabilitations for the inmates so as for them not to regress back to using such substances once they are released to society. While this approach is successful in reducing drug relapse of the criminals for up to 18months upon release, proper monitoring and probationary status must also be implemented to avoid recidivism. Gaes et al. ( 1998) also cites that prison education and work programs improve the inmates’ institutional behavior and promote prosocial activities after the release. By increasing the inmates’ functional literacy, the chances of having a lawful job opportunities also increases. Such an approach also promotes the maturity of the individuals, equipping them with better decision-making skills that are vital for them to keep them away from crime after release. Gaes et al. (199

Enterprise Resource Planning Research Paper Example | Topics and Well Written Essays - 750 words

Enterprise Resource Planning - Research Paper Example The software enables the integration of each and every aspect of operation within the organization including manufacturing, storage/inventory control, sales and marketing etc. The Enterprise Resource Planning software consists of several modules available to a given enterprise based on its needs and the level of technical capability within the enterprise. Each of the said modules is designed for a specific area of the enterprise such as marketing, distribution, product development etc (Nathan 60). No matter which module that an organization has decided to purchase, there are several factors that an organization wishing to successfully implement an ERP should consider (Leon 66). In explaining the success and failures of implementing an ERP system, we are going to take a look at two companies, one that has successfully implemented its ERP system and the second one that was not so successful in its implementation of the same. Starting us off, we will look at how Pratt and Whitney, a large Canadian aeronautics company that successfully implemented its ERP system known as SAP R/3. The implementation of this system took two and a half years to complete. Due to the expansive nature of the company (having customers in more than 170 countries and having over a dozen plants across the globe), the company decided to develop a centralized information processing system to improve on its customer satisfaction. This system was to be named SAP/R3 and through it the company intended to fully i ntegrate its information system through the application of the technology that was available at the time. In particular, this system was aimed at improving customer experience, reduce the amount of work in progress, increase turnover in inventory and finally ensure closer monitoring of inventory and the operating costs (Harwood 120). One of the factors that ensured that the development and implementation of SAP R/3 as a success was the inclusive nature of the project team that was behind this development and eventual implementation. This team was divided into groups and it included employees from all the relevant departments including sales and distribution, information technology, production, planning, materials management and finance. This all inclusive approach ensured that the proposed system would cater for everyone’s needs and desired hence its acceptability across the board. The second factor that led to the success of SAP R/3 was the importance that was placed on trai ning of the employees on how the new system works. Training was undertaken across the departments and nearly all the employees whose functions would require knowledge of the system were accorded this training. The training covered general understanding of how the system works and technical aspects of the system such as basic navigation and how to accomplish the desired tasks. The third factor attributed to the success implementation of SAP R/3 was the effective data migration strategy that was used by the company in transferring data from the old system to the new one. The data was first ‘cleansed’ before being transferred to the new system hence ensuring its correctness and reliability. Finally, the company had adequate capacity in terms of operational activities and technical capability (through its experienced staff) and financial ability to undertake this shift (Wallace 58). Having looked at the success story that is Pratt and Whitney in implementation of its ERP sy stem, we will flip the coin and consider a company that was not as fortunate in its implementation of its ERP system. Target Group is a UK based investment firm that tried to implement an ERP system but due to a number of reasons, this implementation was not as effective as was with the

When should we discard explanations that are intuitively appealing Essay - 1

When should we discard explanations that are intuitively appealing - Essay Example To facilitate the answer to this question, we will discuss and investigate the three key ways of knowing. This entails sense, reason, and perception. There will also be an analysis on intuition’s reliability, as it will enhance its comprehension (see Barrett). Personal demonstration is an ideal answer to this question. This is because was previously addicted to Oreos. There have sugar and fat content of 60%. As a result of my justification, I ate in large quantities. After detail research, I discovered that they contain 2% vitamin C, 4% vitamin A, and 10% of calcium. From this analysis, is evident that, Oreos are highly nutritious, hence intuitively appealing. This was the reason behind my consumption, in reference to the supporting information. However, despite the fact that the study shows that Oreos are nutritious, it is satisfactory that they are healthy. This is as a result of the sugar content among its ingredients. This was an ideal practical example of a situation where intuition was appealing, but on the other hand, it was totally wrong. Regardless of the fact that various situations call for straightforward answers, there should be a detailed explanation before one takes a different turn (see Nabisco Cookies). In reference to the above discussion, intuition is appealing. However, in relation with John Kord Lagemann, a famous author, argues that intuition is not an enemy of reason but it ally. This gives an allegation that suggests that intuition appeals rising from reason should not be given the same treatment as the other intuitions. An example connecting to this theory is the controversy that exists between The Big bang and Creationism. The two theories are bas on intuition; however, they are also based on detailed reasoning. The difference comes in the meaning and interpretation of the theories. Creationism states that there are impossibilities

Go tell it on the mountain by James Baldwin Essay

Go tell it on the mountain by James Baldwin - Essay Example â€Å"He awoke on this birthday morning with the feeling that there was a menace in the air around him’’ (Baldwin 1985, 19). The thought of sinning makes John depressed. John’s relationship with the father deteriorates because of his sin. He feels that obeying God requires submitting to his father. John tells Elisha that: â€Å"Elisha†¦ no matter what anybody says, you remember –please remember-I was saved. I was there.’’ This shows John depressed because of masturbating. â€Å"Then John knew that a curse was renewed from moment to moment, from father to son.†(Baldwin 1985, 288). This highlights John’s depressed state. Sinning is an innate behavior therefore should not cause depression. Instead, one should ask for forgiveness. The bitter relationship between John and Gabriel shows the theme of hatred. There is conflict between Gabriel and his son John. John did not understand the reason of Gabriel’s hate towards him. He tries all he could to appease Gabriel in vain. However, towards the end of the novel, John realizes that Gabriel hate could be because he was not his biological father but his stepfather. â€Å"He lived for the day when his father would be dying and he, John, would curse him on his death-bed.†(Baldwin 1985, 23) .This shows John’s hate for his father. â€Å"Satan, at the moment, stared out of John’s eyes while the spirit spoke.† This quote highlights Gabriel regarding John as a Satan. â€Å"And John did†¦to stare forever into the bottom of Gabriel’s soul.† This shows John disturbed looking for possible reason for Gabriel’s hate. The religious norms practiced by the community are hypocritical. Most of the church leaders and the congregation did not practice the Christian ideals they preached. The fact that Gabriel hated John despite the fact that he was a deacon shows religious hypocrisy. Gabriel does not seem pleased with John even after he became a saint. â€Å"They stood before each other in

Literature as Knowledge for Living Essay Example for Free

Literature as Knowledge for Living Essay According to Vera M. Kutzinski in his introduction, Ottmar Ette was sent to the east of Germany after the reunification of Germany to strengthen academic institutions. There, universities were going to receive the so-called â€Å"Initiative for Excellence†, which would make German universities more competitive. But, when it came to application, a little percentage of humanities institutions were selected, because the focus was actually on science and technology. This fact was what fueled Ette to take a turn on his work and started to work on not trying to convince why literary studies were better or worth more attention or research, but to make skeptical see why society cannot do without literary studies. Ette’s official work on this matter is titled Lendemains, where he focuses on literary studies as something that society needs to survive and the relations established between human beings in literary terms. Below is presented a short review on his evaluation on this matter. Ette argues that literature and language do not seem to deal with language about life any longer. Instead, scientific and technological academic fields have taken over. So what has to be done for the humanities to deal with life again would be, according to him, reorientating the idea of life, which should be based on making society see how the humanities can improve how human beings live with one another, and this should be done together with the biosciences, creating an easily understandable language which allowed scientific and literary discourses to work together as equals. Ette also discusses how biotechnology and natural-scientific fields of study have become the â€Å"sciences of life† because it has been socially accepted, since their subjects of study have to do with life. And also how literary scholars do not pay attention to the humanities losing ground on this respect. So, according to the author, the concept of life should be changed from a bio-chemical, biophysical, and biotechnological and medical, to a cultural-literature-oriented one, as other scholars also maintained before (Leo Spitzer and his ideal of literature being the science that seeks to comprehend the human being to the extent to which he expresses himself in words and linguistic creations). Then, the author introduces the concept knowledge for living as the kind of knowledge inherent to literature, this is, literature having knowledge about or of life. But then, it comes the following question: how to acquire this knowledge for living? This could be answered (according also to Wolfgang Iser’s work) by the act of reading, this is: reading fictional literary pieces and having experiences through it that make the reader gain a kind of knowledge that he/she would not experience in their own life otherwise. This introduces the concepts of intratextuallity (the knowledge of living that characters of novels possess) and extratextuallity (the ways of acquiring certain cultural and sociohistorical knowledge for living), both of which influence the reader culturally, in their behavior, their life, etc. depending on what they read. These two dimensions of the knowledge for living constitute, at the same time, the knowledge for living together, which is acquired by the readers through literature as the conditions for people to live together which have been shaped all throughout history. In these terms, the author mentions Roland Basthers’ work Comment vivre ensemble, and how literary analysis could connect literature and life. This is, for example, how to live (in the novel), how certain people have lived (in biography), etc. In addition, these knowledges should take into account different contexts and cultures, gender and social differences, in order to be universal and valid. The conclusion of the author is that the humanities first need to realize the potential that they possess concerning knowledge for living which, in conjunction with the natural and social sciences, would give new perspectives for the exploration of art and literature as knowledge for living.

Introduction To The Kingdom Of Spain Politics Essay

Introduction To The Kingdom Of Spain Politics Essay Spain officially known as The Kingdom of Spain, it is an independent government and affiliate of European Union. Spain is situated in the south west of Europe on the Peninsula Iberian. Madrid, the capital, is the largest city of Spain with over three million people of the population. The official language is Spanish known as Castellan, but there are recognized regional languages as Catalan-Valencian, Basque, Galician and Occitan that belongs to autonomous comminutes. Their government is Unitary Regional State Parliamentary Constitutional Monarchy, which as of today we find names like The King Juan Carlos I de Borbon, and the Prime Minister Mariano Rajoy. If we look back to the governance of 1978, the Spanish Constitution was the termination of the Spanish transition to democracy, moved by the democratic political reform in 1976 and 1977, the new Spains King Juan Carlos, well known and remembered for his conduct and temperament named a new prime minister and dismissed the one that was there. The new election organized the purpose of drafting and approving a new constitution in 1978. Education is free for Spain from the age of six to sixteen, and the religion is the Roman Catholicism which is considered the principal religion of Spain. Spain is also very well known for their architecture, music and dance, not even considering their cuisine and valuable representatives idols in different sports. The politics of Spain is basically established by the constitution of 1978, which says Spain as an autonomous government, where the people have to elect the Prime Minister for the power of the country. The political form of the Government of Spain is parliamentary monarchy, according to the Spanish Constitution, Tribunal Constitucional de Espana (1978), is a social representative, democratic, constitutional monarchy in which the Monarch is the head of state and the Prime Minister, whose official title is President of the Government, is the head of government.(Article 98). The political system as parliamentary monarchy means a form of an existing government in the current western democracies, especially in Europe, in which the king execute the function of the head of a state under the control of the legislative power (Parliament which are elected members of the state for some period) and of the executive power (Government). The norms and decisions established of the Parliament control not only the procedure or operation of the state, but also the action and functions of their own king. It divides in three different powers of government: Legislative power devises and modifies the existing laws according to the opinion of the citizens. Another function is the approval of the laws and usually, it is on charge of the congress or a parliament, which are composed by representatives elected by the town that has been attributed the main assignment to express the determination or will of them. Executive power dependable in causing to comply the laws and that is used to exercising the government or the own leader of the State. It is responsible for the daily management of the State. The executive power consider and executes general politics according to which the laws have to be applied, represents to the Nation in its diplomatic relations, maintains close the Armed Forces and from time to time advises to the legislation. The President is the visible image and figure and the most important power. Spanish Constitution, Tribunal Constitucional de Espana (1978) The judiciary power is independent of the executive and the legislature, administering justice on behalf of the King by several judges and magistrates. It is the responsible for administering the justice in the company or state, by means of the application of the legal norms (Article 99) Political Ideology Like any other country which has their own government we will find political ideologies. According to Roskin et al.(2009) states that ideologies are often based on theories but simplified and popularized to sell to mass audiences, build political movements, and win elections. Ideologies might be called cheap theories (p.39). Spain has several multi-party systems at both regional and the national level. Nationally it covers only two that are the most popular political dominant parties, which are PSOE (Partido Socialista Obrero Espanol) that is the left-leaning, and the right-wing PP (Partido Popular). On these days the political dominant party is the one that governs in the present. The regional parties can be strong in autonomous communities like Catalonia and the Basque Country due to several conflicts between these two that have been creating national government coalitions. The ideology of PSOE is social democracy and social democracy is a political ideology that considers itself to be a form of reformist democratic socialism. Social democracy rejects the either or polarization interpretation of capitalism versus socialism (Busky, 2008, p. 8; Harrington, 1989, p. 93). This means their belief it consist to be a force social democracy that supports the economy and gives benefits to the population, like unemployment, food stamps, low cost insurance and in some cases totally free. Figure .Political Parties in CongressAccording to researcher Steger (1997), Social democracy in its current form was originally developed by revisionist Marxist Eduard Bernstein who opposed orthodox Marxisms support of revolution and class conflict, claiming that socialism could be achieved through evolutionary means via representative democracy and cooperation between people regardless of class (p. 146). This means this party also means that they can improve the social conditions of the populations by reducing the benefits of the business, making the working class get all credit than the business. The ideology of PP (Partido Popular) is the conservative political party in Spain (Nordsieck, 2011, Parties and Elections in Europe: The database about parliamentary elections and political parties in Europe). This party was a refoundation in 1989 of the Peoples Alliance (Alianza Popular) and it was combined with small Christian democratic and liberal parties. The PP was until November 2011 the largest opposition party in the Congress of Deputies, with one hundred fifty three out of three hundred and fifty deputies, and the largest party represented in the Senate, with one hundred and one out of two hundred and eight senators. Their ideology is central and right, which means that they need to promote the total liberty for business and the state, cannot be involved in the economy. Electoral System Spain uses a majority system (more than half), which in article 68 from the Constitution in the electoral law of 1977 (restructured in 1985) is based on the proportional representation system, that according to Roskin, Cord, Medeiros, and Jones, (2009) states that proportional representation system elects representative by partys percent of vote, which means each district sends several representatives to parliament, not just one (pag. 70). The minimum of deputies must be three hundred and the maximum four hundred members of the parliament that are elected by free, direct, equal, and secret vote for a four year period, it must obtain a minimum of three percent of the vote in order to qualify for parliamentary representation. The voting system used is that of proportional representation with closed party lists, that mean voters can only vote for political parties as an entire party and they have to decide who ever gets the highest positions is tend to get a sit in the parliament. Following DHondt method a mathematical formula which slightly over represents the larger parties at the expense of the smaller ones (Roskin, Cord, Medeiros, and Jones, 2009, p. 71) in every providence of Spain the electoral vote or suffrage must be assigned by a minimum of two deputies per providence, this includes the autonomous cities (out of Iberian Peninsula) of Ceuta and Melilla, each of these two has to assigned only one deputy. Legislation can be opened by the Congress of Deputies and they are assigned to approve or refuse the laws adopted by the executive government. They also have the power to elect, the prime minister or the President of the Government. The prime minister can be removed from his duties due to a vote of confidence from the elected parliament, and then it needs to be substituted. Election system also helps to major political parties because not only provinces wit small populations are over-represented. Spain has two party systems that smaller and regional parties posses small representation, due to difference in population between providences, when the provinces are totally represented, the deputies is small comparing to one or two major parties, even if other smaller parties managed to obtain more than three percent of the votes. The three percent to get in the Congress is unsuccessful in many provinces, where the number of seats per constituency has a lower average that the actual deputies to be inside the Congress is effectively higher, for example, the actual number for the provinces having three seats is twenty five percent, much higher than three percent, however, in provinces such as Barcelona and Madrid, while the number of seats is much higher, the three percent to get it the Congress is still helpful to get rid of the smallest parties. Government intervention in the Economy After Dictator Francos death, Spain passed a change to democracy in the middle of 1970s, even though a quickly procedure of modernization happened, the Spanish welfare state was seen until now, that has been relative turned out week. There is a list of the main problems this consequences has left is that the attention has turned to be a governance issue, the interplay among levels of government, the welfare mix and public support for social policies. Another issue tell about the five most important challenges the Spanish faces with welfare state in the present century is the purpose to have a better life, to achieve a better work family balance, to organize migratory policies with existing social defense, to attempt the resolution of high rates of poverty, and to face intense population growing, both in terms of increasing needs for care and the modification of the pension system. Social welfare benefits little by little have grown. Spain gives generous retirement remuneration and st rong unemployment benefits; as per now it offers no welfare benefits. Political Culture The political culture is about the perception and the interpretation of the norms and values that each society implements to the people. The political system plays a role really important because of the ideas might be implementing how to work with the government and what they can do. The political culture is the symbols, values, and beliefs about the political system which is determinate by the history, economy, religion, and folkways. (Roskin et al., 2009, p. 119) It is related to the memory of what the nation have done previously, like in the last decades Spanish society and politics contributed the incapacity to maintain a firm and secure government very independent prior 1970. People believe and think the transformation of the democracy was possible by the socioeconomic modernization, the decisions, and the cultural change from political elites of democratic institutions and the conduct from some parties involved in the benefits to Spain. Unfortunately Spain does not have a good background in history, an excellent example which can be seen today with the autonomous communities, such as Catalonia and Basque country, that both are looking for independence, being away from Spain, creating regionalism and issues between all communities. Many questions fly around about the way of how the government and the politician need to act different or at least try to be similar and competitive with the neighbors governments. Perhaps the introduction of Spain to be inside the Europe Union have created in the meanwhile, that the present crisis should bring some common sense agreement to have a better workability in the political culture of Spain. Public Opinion The Spanish society is having many difficult times due to the current crisis; there is dissatisfaction with the social management carried out by the government. The rate of unemployment is one of the main reasons resulting in various popular events such as the irritated people and this is added to the labor reform that get problems to the labor rights of the Spanish workers. Another reason is cutting the health and education sectors and the raise taxes to reduce the Spanish deficit. The twenty seven thousand three hundred million of Euros in reduction in public spending joined a week later, a cut of ten thousand million in health and education. The eighty three percent of the budget reduction corresponds to the direct public spending, most in sensitive areas of social policy. These cuts will be punished more severely to the low-income women, young people, and the immigrant population. The difference between the efforts to increase the collection and the measures of mark get a tendency as regards social rights. According to the latest survey from Gaby Orà © Aguilar (2012) states that the living conditions of the year 2011, in Spain, twenty two percent of households live below the poverty line. The poverty rate rose by more than two percentage points between 2009 to 2011 (p.4). At the end of last year, five hundred thousand homes in Spain received no income for job, or unemployment benefits or social security; which means they were in extreme poverty. Religion in Spain The largest religion is known as Roman Catholicism which is led by the Pope. According to a study by the Sociological Research Spanish Center (2011) testify that about seventy percent of Spanish self-identify as Catholics, three percent as other faith, and about twenty five percent identify with no religion (p.13). Most Spanish, especially the younger generations try to avoid the religion differences compared to sexuality, morals, and politics. Spanish also consider the religion as part of the three most important values. Spain has also gone thru with the legalization of the gay marriage, actually there is a seventy percent of Spanish that support their marriage. (Study by the Centre of Sociological Research, 2004). This case was along from a split vote from the conservative liberal lines with the Spanish Socialist Workers Party and the other left party supporting while Peoples Party is against it. Spain also during the immigration process and the introduce of new cultures in the population, especially during and after the 1990s, have them led to an increment number of Muslims (God as related to prophet Muhammad) and have about one million of members. Along with the introduction of new religion as part of the immigration, people from Latin America which are known as strong Catholic practitioners have helped the Catholic Church to maintain part of the assistance for those who go to church on Sundays. In the last decade, political issues and the enrollment of the Catholic Church has increased again, especially for groups such as Opus Dei, Legion of Christ (Catholic Church Institution) with the participation of important politicians in the right-wing such as Popular Party. Opus Dei is an organization that their mission is to get closer to God, to serve the most needed it and to improve society. In more recent times, some members of the Opus Dei were chosen ministers by the then leader of that party, in any case, since the institutional point of view, the Opus Dei does not have an official political position, there is few worries that many of their members are politically conservatories just like the common of the Spanish Catholics. The members of the Opus Dei remind that the institution has a spiritual principle and that each member takes their professional responsibilities in the politics or the business without doing participants of them to the others member and even less to the institution. They said that the Opus Dei could have the political position they wanted, as long as they did not go in disagreement with the catholic principle. The church is not the independent and neutral institution in political affairs, and everything is related with the opinion of the Popular Party which it gain consequences that the new disapproval from important sections on the population, especially the biggest part of the left party that has the opposition against the church and the way in which it is economically sustained. Political Communication The mass media have always shown opinion in the civilization in politics. Political communication is the opening of how a government can be criticizes by public opinion like radio, newspaper, news channels, not even nationality, worldwide too. In these days, the audiovisual media market has positioned traditional print media, which means the press uses pictures and color to write or edit the news into television or journals. After Spain became democracy, the mass media practiced an increase to inform the civilization especially by newspapers. In these days most popular medias have gone online. The historic and significant newspapers in the past, such as La Vanguardia, ABC, El pais, and El mundo were part of the important media companies. According to Holtby (1990), he stated the reputation and expansion of these journalists were written by some of the most well-known writers of the Spanish language, from Spain and Latin America such as Miguel Delibes, Gabriel Garcà ­a Mà ¡rquez. Jose Camilo Cela, and Carlos Fuentes (p.336-338). Radio had a big impact on the Spanish communication. Taking into consideration to the Civil War, the radio was the principal tool of government propaganda, after that war the Francos forces detained republican distribution stations. During Francos period, coverage for all news national and international was official managed by Radio Nacional de Espana. The difference from the print media, radio did not apply a practice of liberalization, and after some restrictions it was finally eased. According to Gunter, Richard and Jose Ramon Montero (1999) the most important radio networks in Spain are RNE, Sociedad Espanola de Radio Difusion (SER), Cadena de Ondas Populares (COPE) and Onda Cero with a highest audience (P.176). In the same way as the other print media and televisions, radio has established a very important role in the culture and the identity of the autonomous communities like Basque Radio, Galician Radio, and Catalonia Country. It is estimated that over ninety percent of the population watches television. In terms of audience size, TVE1 and Antena 3 have the greatest numbers of viewers. Spanish television has developed from a state owned institution, which it represents the views of the government and was seriously covered up to one that tends the views of particular regions, a more European viewpoint, and the demands of the public in general. Most of the Spanish people receive the news from television and not from the print media. Online newspapers in Spain are a new experience, and they report for 17 percent of the distribution of web traffic. It started with the new technology that media in Spain has been implementing during this years as online publications. Most of newspapers started implementing their information online since 1994. Interest Groups It is related to the influence of groups against the government that might be permanent or momentary. The term of interest group covers just about any collection of people trying to influence the government, some interest groups work through the executive or administrative agencies, others through the judicial or legislative sectors (Roskin et al., 2009, p. 177). Some of them are concentrated to influence the political parties and the other on just particular changes such the private interest. In Spain most of these groups work together to persuade the government and become powerful. Sometimes interest groups participate in government; Catholic Church has participated in the Spanish Constitution which advice the liberty or freedom as well as the Church and State keeps away from each other, but also indicates that the public powers will keep in mind the religious beliefs and they will maintain the consequent relations of cooperation with the Catholic Church. (Article 16 of Spanish Constitution, 1978). The Catholic Church is excused to pay income taxes like the nonprofit companies and they were not able to pay taxes on some religious cultures or objects. Same thing happens for the conservation of the building that are considered cultural patrimony, which it is financed by the State and foe other public funds too. It is mandatory that primary and secondary schools offer in their academic program the class of religion, even though the students can choose to study a different alternative class. Chambers of commerce is a form of business network that their activity is to get together group of business people to recognize, create, or to prepare business opportunities. They are also considered as a interest groups due to their activity could create a public model to the sectors of the government because it is common in the European Union countries such as Germany, Italy, France, and also in Japan. The principal assignment of the chambers is trade promotion, vocational training, regional economic development, and general services to their members. It shows the possibility of a business individual to make innovative business associations and produce business opportunities at the same time. In Spain, the government could give the chance to some chambers to take responsibilities of public administrations in many fields, they also have a consultative or counseling occupation; this mean any chamber selected can ask for consulting ideas whenever a new law is related to the industry o r commerce. (Markus Pilgrim, Ralf Meier, 2011). ETA, a short form  for  Euskadi Ta Askatasuna,  which means Basque Homeland and Freedom is an armed organizations that looks Euskadis independency. The general idea they have with the government is that they achieve attacks like murders, abductions, car bombs, and more to all politicians or public images in the media. Once they create a terrorist environment it starts a high to the fire which means they need to stop using the violence and it will create a negotiation between them and the Spanish government to accomplish their objectives. Elections The electoral elections are carry out every 4 years, but sometimes it could be an agreement that some elections would be anticipated, this mean when the 4 year period it is not finalized. The requirement to vote is to have the Spanish nationality and to be legal age that is more than eighteen years old. The citizens must register in the electoral census to justify the people who vote is legally to do it. Votes are not mandatory for everybody, if you need to suffrage will be voluntary option.

Electoral System (Statistic National Institute) In the last elections, citizens have voted the sixty nine percent of total population, which means it has descended a seven percent with respect to the past general elections. From the total of twenty four million six hundred sixty six thousand and thirty ninety two votes, it has been that make it count. Political Party System Political parties connect the people thru the government. In these days Spain has several multi-party systems at both regional and the national level. Nationally it covers only two that are the most popular political dominant parties, which are Spanish Socialist Party (Partido Socialista Obrero Espanol) is the left-leaning, and Popular Party which leads the right-wing that describes as conservative on social questions and free market. The Popular Party is the current dominant party that represents Spain. The Spanish Socialist Party was created for the intention to represent and to protect the benefits and interests of the hard-working class of the industrial revolution in the nineteen century in the beginning of the democracy. In the other hand the Popular Party is the conservative political party of Spain founded in 1989, it is known as central reformist, they need to promote the total liberty for business and the state, cannot be involved in the economy. The Popular Party, recent winner of the past elections in November 2011, has plain majority in the Congress of the Representatives and Senate and governs in eleven autonomous regions (Paddy Woodworth, 2011). As all political parties it uses a imputing devices that allows citizens to get their needs by the government. If society votes it gives the chance to participate in political decisions. Popular Party and Spanish Socialist Party signed in 2000 the called agreement by the liberties against the terrorism, which voided the relationships related to the terrorism of the political debate among both parties by interest aggregation. Spain currently is a country decentralized that has recognized the territorial order of the power around the state has been called autonomous; this means the government offer total liberty to the autonomous communities to government by their own. After Francos death and with the intervention of the King Juan Carlos I in the beginning of the Headquarters, a new political period was opened that was consolidated with the victory of the Law for the Political Reform. During the campaign all parties coordinated the elaboration of the new constitution and the establishment for the autonomy for each region. The coherence of all parties involved in the democracies will execute as they agreed, if they become elected. The Popular Party is financially support by three different aspects; first they get money from subsidies institutions for political parties, quotes and anonymous donations of participants or followers supporters, and bank credits. According to the report of the Court of Accounts of the 2003, the Popular Party had a debt of 8 million euros, being the political party with group in the Congress in owing less money (Pedro Ramirez, 2007). Now most the money they received are constituted in donations from anonymous contributions. Spains Party System is majority (more than half), which in article 68 from the Constitution in the electoral law of 1977 is based on the proportional representation system, which means each district sends several representatives to parliament, not just one. Government and the Economy In other terms each country has relationships between the government and the economy, in this particularly case political economy study the distribution to sell and buy goods, the production that declares thru customs of what is coming in and out. To see how the production of Spain is we must identify their GDP which is a equivalent of the production of goods and services in a country over a year. Below I will show you the record of Spains GDP over last twelve years: Years 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 GDP 5.0 3.7 2.7 3.1 3.3 3.6 4.1 3.5 0.9 -3.7 -0.1 0.7 -1.0* Figure 3. Real GDP growth rate volume We can see how the GDP was maintained firm from the two thousand to the two thousand and seven, with the higher point in two thousand year with almost five percent. After that GDP falls to one percent of the total value produced in two thousand eight to two thousand nine passing from one percent to three percent negative due to the crisis and that it is called recession. The following years it still being negative with a little improvement in two thousand and eleven but went down this year as today. As we saw in two thousand and eleven the development of GDP was superior, this happened due to the value of that year has been so low because the families consume less as a result of the few incomes that they have, in addition businesses invest little regarding the low financial procedure. As of today the internal demand do not let them increase as some families do not spend or buy goods, this lead the business are not producing as before for the recent crisis Spain has been going thru, and it is hard to obtain a loan to be able to carry the production. Banks are not giving credit loans and the labor class has been inactive as construction stop while ago when it was the well maintain before. Inflation is the increment on prices of goods and services with related to the money maintained in a specific time period. Figure 3. Real GDP growth rate volume Principally inflation happens because there has been little incomes, and the tax has been lower without excluding the expenses up to now that there are many ways to help to keep the situation stable by the crisis. A good example is government rise the taxes to collect more money, increasing taxes on tobacco and alcohol. Political Violence Political violence means groups of people trying to intimidate the government to achieve political goals. These groups of violence people will try to get the government attention if they will not respond to their political demands. Violence could be considered as violation of human rights, war, police brutality, kidnapping, torture, terrorism, revolution, dictatorship, etc. Spain has many horror stories in their history; the most catastrophic attacked was in Madrid in two thousand and four. They were victims of terrorist attached produced by Al-qaeda with the explosion of bombs inside the trains. One hundred ninety one people passed away and one thousand eight hundred fifty eight got injured. At the beginning of the seventys, Spain had a modern economy but a political system based on the dictatorship which was not democracy as well all the European countries. Franco named General Carrero Blanco to stay in command of the government but after six months he was murdered by ETA. In November of nineteen seventy five, the General Franco died and the constitution was changed when King Juan Carlos Borbon was named king of Spain. Just then he began the transition of the dictatorship to the democracy.

Tennis Ball Investigation :: Papers

Tennis Ball Investigation Aim: Investigate the factors that affect the bounce of a tennis ball. Key factors (variables): 1) Height of drop 2) Surface of bounce 3) Gravitational pull 4) Room temperature/ball temperature 5) Weight of ball 6) Material of ball 7) Brand of ball 8) Age/wear of ball 9) Size of ball 10) Force of drop/push How the key factors will affect the bounce: 1) The higher the drop the higher the bounce 2) The harder the surface the higher the bounce 3) The weaker the gravitational force the higher the bounce 4) The warmer the ball the higher the bounce 5) The lighter the ball the higher the bounce 6) Discontinual-unknown 7) Discontinual-unknown 8) The newer the ball the higher the bounce 9) The smaller the ball the higher the bounce 10) The more force put into the drop/push the higher the bounce I have chosen to investigate 1) Height of drop. Prediction ========== [IMAGE] I believe that the higher the height the ball is dropped from the higher the bounce, because when the ball is lifted the higher it is lifted the more energy is needed to lift it. Therefore more energy is converted from chemical potential energy in the body, to kinetic energy when the ball is being lifted, to gravitational potential energy (G.P.E) when the ball has been lifted to the height of the drop. The more G.P.E the ball has a the start of the drop (point A), the more energy is converted to kinetic energy while the ball is dropping and then to elastic potential energy (E.P.E) while it is static on the floor (point B). At this point the ball looses a percentage of its energy to sound and heating the floor. I know that it is a percentage of its energy that it looses rather than a fixed amount because I know that the more energy the ball has the louder the

Holden in The Catcher in The Rye Essay -- essays research papers

The author has put in plenty of themes, messages, ideas, issues, and motifs. The character, Holden Caulfield is alienated from society, is experiencing the painfulness of growing up, thinks that the adult world is full of phoniness, and is sick of hearing about the American Dream from his teachers. JD Salinger has created a book that has raised plenty of questions and controversy towards the readers. The Catcher in the Rye shows how a teenage mind works. JD Salinger has used a stream of consciousness writing style where the character (Holden Caulfield) talks in first person as he presents his thoughts and feelings to the readers. The setting has taken place in the early fifties and the book uses a lot of profane words. The New York vernacular helps to explain the plot and help define the character. The Catcher in the Rye clearly states that Holden is an individual trapped within a heartless world. He is victimized on the other side of the world but he tries to get in the world which he feels that he does not belong in. Holden wears a red hunting hat as a symbol to show that he is a rebel against the law. By criticizing others, that is the way Holden hides away from his fears. â€Å"Pencey was full of crooks.

Tess Of The D Urbervilles - Finding A Place In Life :: essays research papers

Finding A Place In Life By human nature, people need a sense of belonging to be happy and fulfilled in life. It is more difficult for some to achieve this goal than others. Having friends and being loved is an important part of life for most people, yet if this is difficult for them to achieve, this goal could consume their life. This is true in Thomas Hardy's novel Tess of the d'Urbervilles, where Tess, a descriptively pretty young girl goes to great lengths to find her place in the world. She moves from town to town searching for her place in society. She first settles in the city of Marlott where she leads a simple life. "Tess at this time of her life was a mere vessel of emotion untinctured by experience" (Hardy 11). Tess continues to travel to different towns in hopes she will improve her life by finding the person she wishes to spend the rest of her life with. Throughout all this disruption in her life, "she is an ambitious woman in search of a new sensation" (Hardy 15). She continues to travel because she wants more from life and has the ambition to attempt to find her place. Tess had to cope with many threatening, dangerous, and sad situations during her search. The first occurs when she arrives in the growing town of Tantridge. There she worked as a dairymaid on the Flintcomb-Ash Farm. Even with her dislike for this job she continues to work at it for over two years until she knows for certain that this is not her place in the world. As she "progresses (she) wonder whether it would be wiser to return home. The resolve, however had been taken, and it seems Vacillating†¦ to abandon it now, unless for graver reasons" (Hardy 67). As she continues to live in Tantridge, she gets into fights, drinks, and ends up being raped and impregnated. Alec is the man who attempts to convince Tess that she belongs with him, and that they were meant to be together. In her heart Tess realizes Alec is not the man she wishes to be with. Unfortunately she continues on in the one-sided relationship which leads to Alec raping Tess. She does not yet know how s evere the consequences are for not being a pure woman. This idea of being a pure woman is so important in this period of time that Tess keeps it a secret even from Angel, who is her new love and the man she wants to spend the rest of her life with.

Control System- Pressure Regulator

A type or certain group of elements that function together as a unified whole, is a system. This widened description thus gives some meaning to control systems as a whole. By re-establishing the basic principles and functions worked out, a system's limit can be extended to include little or more characteristics just as long as each singular variable contributes in a way to the particular system activity. This explains that the system does not halt interaction to other systems or peripherals. In the process industry, the term control system is sometimes normally used to specify a process, and the apparatus basically required to run the process. The system is tested with various actions so it will conform to a standard, these include; load, commands and disturbances which cause it to respond in some individual manner. A system is best made so that it will respond positively. In order for a system to act in the way prescribed is to control the system. The basic concept of comparing the measured and prescribed system performance, and then taking any action to change the process thereby minimizing errors, is called negative feedback. The system can vice-versa be called a closed-loop control system, or a negative feedback control system. To make a system automated it should be mechanized. To create the maintenance of a constant value in a control, is not the major primary objective of control; once the prescribed behavior is achieved, the control function is fulfilled. Although the use of control measure is in most cases involved with mechanical equipment, they can also be used in fields such as (e.g. in the social, biological or in different other systems). The science of achieving control, by using or not using feedback, is the method of control theory. This is applicable to system control in general. Most control systems have evolved by the practice of trial and error, for the critical design of system controls with the need for extensive analysis of two factors, the control devices and the process. 2.0 TYPES OF REGULATORS- 2.1 SIMPLE PRESSURE CONTROL SYSTEM (SELF OPERATED REGULATOR): For a typical uncontrolled system, let us say it is required for it to provide a standard pressure, P, at a given measure and that the discharge, Q2, provides for an external system, which, its need for this fluid varies. At a given time interval, the external system regulates valve No. 2 to comply with the needed specifications. The curves given in Fig 1.0 FIG 1.1 Shows the way in which it alters the process of the pressure. In earlier results in time, t1, some initial stable condition exists where, Q1 and Q 2 are of the same and the process pressure is significantly at the aimed equivalent. A level change occurs at, Q1 when time is at, t1, this reduces the fluid mass between the valves. This is followed mainly by a drop in the process pressure. For a system which is uncontrolled the pressure decline will continue until the drop over valve No. 1 is enough again to build equal flows and a new constant state functioning condition is gained. The procedure can be controlled; i.e. the suitable needed pressure can be managed if the significant rise in Q1 were gotten by increasing the opening of valve No. 1. A typical way of doing this is given in Fig 1.1. FIG 1.3 The response for the process pressure is sent to a spring opposed diaphragm that gives free way for the pressure to manoeuvre the valve. In a working mode, the contraction in the spring will be set so that at some constant state working condition the required process pressure, acting on the diaphragm section, this balances the force that the spring carries. The aimed process pressure is known as a set point. Changes from the set point which is caused by load variation will be controlled because as the process pressure differs, the matching force given back to the diaphragm will regulate the valve position to reduce the pressure variance to a certain range of value around the set point. The careful control of the pressure will rely on how big a flow change the regulator will be able to carry out for a minimal amount of pressure. The regulator flow change to process pressure change is the gain of the regulator and this will rely on the diaphragm area, the valve size, stiffness of the spring, and the general pressure drop over it. The corrective activity done by the regulator is proportional to the change of the process from its set point. Such an element is called the proportional or proportional mode, control. When using the proportional control, the corrective action can only carry on when some different outlines exist. The final pressure change needed to completely stroke the regulator is known as the proportional band and it shows around what limits the regulator can control. FIG 1.4 illustrates where the process measurement supplies the whole valve actuating force, this is known as self-operated regulators. FIG 1.5 The above demonstrates a self operated regulators made for the control of temperature, flow and level. The operation method is practically the same with the pressure regulator. They are widely used in various applications of specialty in the industrial field. 3.0 PILOT OPERATED PRESSURE REGULATOR: This regulator uses a little pilot valve assembly to aide in actuating the main valve. Generally the pilot operated pressure regulator shown in Fig 1.6 FIG 1.6 when in operation, the process pressure works on the lower side of the main diaphragm which is similar to the self operated regulator. The pilot also quantifies the process pressure and, upstream pressure as power source, changes the loading on the top side of the main diaphragm. The diaphragm serves as an amplifier, generally bearing a gain from process to loading pressure of 10 to 20 psi per psi. This is because of both feed back path ways one through the direct one and the other through the pilot, the regulators demonstrate a more complex control action than the simple proportional mode. The pilot operated regulator are available for all the four major process variables; flow, pressure level and temperature even though the direct acting path is left out in some cases. With the pilot operated regulator it is generally easier to achieve a greater regulator gain. Both the self and pilot operated regulators share similar attributes that have, in many cases, brought about some restraints. In some instances like if the fluid is corrosive, loaded with contaminants or of very high temperature, apparent issues may arise. Essentially at most one of the diaphragm casings, should, be able, to hold the maximum process pressure. The most possibly vital deficiency, from, the basis that static and dynamic elements of any specific form of process; i.e., level, pressure, etc. can differ respectively from one installation to the other so the choice of the amount of gain to be designed into a regulator without causing any sort of system instability, is made a very tasking procedure. It means that the regulator can not be altered to suit the characteristics of the process to which it has been applied. This Fig 1.7 is the block diagram of a pilot operated regulator FIG 1.7 3.1 INSTRUMENT CONTROL: The pressure control system illustrated in Fig 1.8 FIG 1.8 it surpasses all the limits considerably attached to the self and pilot operated regulators. It generally contains three detachable hardware pieces: the process controller, the control valve, and the valve actuator. Other controllers such as this stands for one of an entire family of peripherals generally referred to as instruments. The process fluid touches only the control valve and its sensing element. This is a small part which has no orifice and could get contaminated. They can be made from several types of materials to achieve high standard against corrosion and temperature. An external source for pneumatic power is used for working parts in the controller to provide clean, dry instrument air. The air supply is regulated so that the pressure is at a standard rate and that the controller and actuator are made to work with a standard pressure signal level, free of the process fluid pressure. A regular standard pressure supply is within 20 psig with a usual ranging of signal within 2 to 15 psig. They are ready for use with numerous sensing element and they give the significance of the process which is being controlled. They are commonly known as indicative controllers. To minimize trial and error the set point is normally calibrated to generally prevent subsequent start ups. The Fig 1.8 is like most pneumatic controller models, it has two levels with an adjustable measure of response and amplification around both levels. The input variable moves an end of a beam which holds the air flow through a nozzle. The pressure of the nozzle is sensitive to the point of the beam itself. The pressure of the nozzle performs on the top diaphragm of a pressure equal valve assembly that is the second amplifier level. As a result of the huge valve ports it is has the capacity to give an extreme flow progression to the actuator which works as a power amplifier. The pressure is given back to the amplifiers which moves the nozzle beams in a direction which opposes the sensing effect. Element motion ( i.e. negative feedback ). The three way valve behaves as a pressure divider and its regulation decides what amount of feedback should be consumed. Leaving the dynamics out, the controller can be seen as having a high gain movement path with a regulated gain response path. It provides only proportional control mode but its area of reach can be freely adjusted over a vast range by means of the pressure divider. The purpose of the integral mode is to remove any steady state process deviation and the reason for the deviation mode is to give an improved transient control. These modes improve the flexibility of the controller. 4.0 COMPUTER CONTROL- The reason for central control is to bring to a particular location, adequate information and hardware to allow an operator to control the plant variances, which are product yield and quality, and to manage the automated control of process variances, which are flow and temperature. In order for all duties to be carried out by the operator must have a sound knowledge of process variances, but how they should be. The adequate values for the process variances will differ as operating circumstances may be affected by things such as contamination, variations in reactants, load, changes in the products wanted or quality. The set points calculation can be made from the plant requirements and information about the plant operating elements. The early use of digital computers for process controls was for plant performance calculation the whole system works in an automated form sampling of transmitter signals.

Industrial Control Process. An Introduction to Hardware .1st edn. Marshaltown, Iowa: Fisher Controls Co. pp. 83-92. 5.0 CONTROL ELEMENTS- 5.1 BASIC ELEMENT: Any system can be broken down into various divisions for understanding it's rather important to consider two levels of dub divisions. The first are those components in a control loop that are manufactured, tested, purchased and even design as standalone pieces of equipments. 5.2 MATHEMATICAL MODELS OF PHYSICAL DEVICES: The mathematical representation of physical devices can be done with the use of the fundamental physical laws which include Ohm's Law Newton's Laws, flow equations, conservation of mass and energy, etc. The use of impedance is often but not always helpful when deriving a mathematical model when a system is dynamic there is a circumstance which is forcing the change. This force is always some kind of potential energy .When a change occurs that is the dynamic system which is a movement known as flux. This flux generally depends on the physical characteristics of the system. Some forms of flux are shown in Table 1.0. TABLE 1.0 Impedance shows the mathematical relationship between potential and flux, it is the ratio of an increase change in potential to an increase change in flux. EQUATION. 1 LLOYD, SHELSON, G AND ANDERSON, GERALD, D. 1971. Industrial Control Process. Basic Elements.1st edn. Marshaltown, Iowa: Fisher Controls Co. pp. 93-94. 6.0 PROCESS CONTROL SYSTEM The performance of a process control system is calculated by considering the system's output to the set point. The difference between both amounts is error or system deviation .The response of a regulatory system, for a step increase in load. Many standard words are defined in the schematic and several of them are used to describe the mistakes which might occur. It is obvious that no certain way such as settling time, maximum value of transient deviation, steady- state deviation gives a measure of system performance. Different approaches methods have been used for the error index. A tank which has several sources of flow as given in Fig 2.1 can be easily described by using block diagrams and flow components. For easy understanding lets say Pc = constant. The equation for flow is: PRESSURE PROCESS STEADY FLOW (FIG 2.1) In order to illustrate the nature of a process control system consider Fig 2.2 for the control equipment has a valve, diaphragm, actuator, and a locally mounted PI measuring controller FIG 2.2 LLOYD, SHELSON, G AND ANDERSON, GERALD, D. 1971. Industrial Control Process. Process Dynamics .1st edn. Marshaltown, Iowa: Fisher Controls Co. pp. 202-204. 7.0 ACCURACY AND SENSITIVITY 7.1 ACCURACY â€Å"In general, the greatest accuracy-closest regulation-is obtained with the largest diaphragm and shortest range which will give the required control pressure. For example, a control pressure of 40 psig can be obtained with any of the three ranges in model RP-1065-A and with two of the three ranges in model RP-1066-A. Closest regulation can be expected with the 5 – 50 psi range of model RP-1066-A (size 10 diaphragm). See table for â€Å"Accuracy of Regulation.† Unbalanced port areas are not considered in the values tabulated. Small amounts of unbalance are present in single-seated 1/2†³ â€Å"A† valves and in semi-balanced double seated valves 2†³ through 4†³. Under conditions of high pressure drop, the forces opposing valve closure will influence selection of the regulator model (diaphragm size). See â€Å"Accuracy of Regulation† tabulation for actual port area unbalance† FIG 2.3 [WWW] http://www.skilenvironmental.com/documents/160_RP1065A_1066A.pdf In addition what changes can made to the diaphragm area, spring rate, orifice size, and inlet pressure, the regulator accuracy can be enhanced by simply putting a pitot tube. Internal to the regulator, the pitot tube joins the diaphragm cover with a low-pressure, high velocity region inside the regulator body. The pressure in the area will be lower than P2 when it goes downstream. By using a pitot tube to calculate the lower pressure, the regulator change in its response to any change in P2. The pitot tube tricks the regulator. 7.2 SENSITIVITY The principle of operation and loading, actuating, and control components are in all designs. Many regulators use simple wire coil springs to control the downstream pressure. Numerous size springs are used to allow regulation of the secondary pressure around a target range. The needed pressure is at the centre one-third of the rated outlet pressure range. In the lower end of the pressure range, the spring loses some sensitivity; at the high end, the spring close to it maximum capacity. Regulators can use diaphragm or piston to detect or sense downstream pressure. Diaphragms are more sensitive to pressure variations and react quicker. They can operate where sensitive pressure settings are needed (lower than 0.04 psi). Pistons generally are more rugged and give a larger effective sensing area in a particular size regulator. The functional difference between general-purpose and precision regulators is the degree of control accuracy of the output pressure. Output pressure accuracy is gotten by the droop due to flow changes (regulator characteristics). [WWW] http://machinedesign.com/article/pneumatic-pressure-regulators-1115 8.0 FEEDBACK This section will develop the performance limitations imposed by a particular load when a conventional flow control valve is utilized in the valve-actuator component. It will then show that the load versus flow characteristic of the forward loop can be modified very advantageously. Various techniques utilized in the past for this purpose, such as controlled actuator by-pass leakage and structural feedback, are compared with a new technique called dynamic pressure feedback (D.P.F.). The analytical work is fortified by reports of actual tests of a representative system. The electrohydraulic position servo can be represented by the block diagram shown in Fig 2.4. This diagram separates the valve-actuator integration from the hydraulic and structural compliance of the actuator. The diagram also represents the particular load case under discussion. The analysis of servo stability and performance is affected by the choice of position feedback location. Output position can be measured at the actuator or at the load. If the feedback is from the actuator position, the analytical task is made more difficult. However, it is apparent from the block diagram that the quantities Xp and X0 react in a proportional manner to inertia forces. It is reasonable to conclude, therefore, that the two cases should yield similar results. This discussion will be based on selection of feedback intelligence from the load position, X0, due to the relative simplicity of analysis. However, a careful comparison of this simpler case with the more difficult to analyse case of actuator feedback position has been carried out. An analogue computer was utilized for this comparison. The results of the study confirmed that the two cases are really very similar in dynamic performance achievable. The use of actuator position feedback suffers some comparative penalty statically with respect to error introduced by external (load disturbance) forces.† [WWW] http://www.emeraldinsight.com/Insight/ViewContentServlet;jsessionid=6464D27CC3E73FAFE7C6220F352B4F85?contentType=Article&Filename=/published/emeraldfulltextarticle/pdf/1270320604.pdf FIG 2.4 [WWW]http://www.emeraldinsight.com/Insight/ViewContentServlet;jsessionid=6464D27CC3E73FAFE7C6220F352B4F85?contentType=Article&Filename=/published/emeraldfulltextarticle/pdf/1270320604.pdf 9.0 PRESSURE MEASUREMENT â€Å"Fluid pressure can be defined as the measure of force per-unit-area exerted by a fluid, acting perpendicularly to any surface it contacts (a fluid can be either a gas or a liquid, fluid and liquid are not synonymous). The standard SI unit for pressure measurement is the Pascal (Pa) which is equivalent to one Newton per square meter (N/m2) or the KiloPascal (kPa) where 1 kPa = 1000 Pa. In the English system, pressure is usually expressed in pounds per square inch (psi). Pressure can be expressed in many different units including in terms of a height of a column of liquid. CONVERSION UNITS FOR COMMON UNITS OF PRESSURE (TABLE 2) PRESSURE TERMS RELATIONSHIP (FIG 2.5) Table lists commonly used units of pressure measurement and the conversion between the units. Pressure measurements can be divided into three different categories: absolute pressure, gage pressure and differential pressure. Absolute pressure refers to the absolute value of the force per-unit-area exerted on a surface by a fluid. Therefore the absolute pressure is the difference between the pressure at a given point in a fluid and the absolute zero of pressure or a perfect vacuum. Gage pressure is the measurement of the difference between the absolute pressure and the local atmospheric pressure. Local atmospheric pressure can vary depending on ambient temperature, altitude and local weather conditions. The U.S. standard atmospheric pressure at sea level and 59à ¯Ã‚ ¿Ã‚ ½F (20à ¯Ã‚ ¿Ã‚ ½C) is 14.696 pounds per square inch absolute (psia) or 101.325 kPa absolute (abs). When referring to pressure measurement, it is critical to specify what reference the pressure is related to. In the English system of units, measurement relating the pressure to a reference is accomplished by specifying pressure in terms of pounds per square inch absolute (psia) or pounds per square inch gage (psig). For other units of measure it is important to specify gage or absolute. The abbreviation .abs' refers to an absolute measurement. A gage pressure by convention is always positive. A .negative' gage pressure is defined as vacuum. Vacuum is the measurement of the amount by which the local atmospheric pressure exceeds the absolute pressure. A perfect vacuum is zero absolute pressure. Fig 2.5 shows the relationship between absolute, gage pressure and vacuum. Differential pressure is simply the measurement of one unknown pressure with reference to another unknown pressure. The pressure measured is the difference between the two unknown pressures. This type of pressure measurement is commonly used to measure the pressure drop in a fluid system. Since a differential pressure is a measure of one pressure referenced to another, it is not necessary to specify a pressure reference. For the English system of units this could simply be psi and for the SI system it could be kPa. In addition to the three types of pressure measurement, there are different types of fluid systems and fluid pressures. There are two types of fluid systems; static systems and dynamic systems. As the names imply, a static system is one in which the fluid is at rest and a dynamic system is on in which the fluid is moving†. [WWW] http://www.scribd.com/doc/2339144/Understanding-Pressure-and-Pressure-Measurement 10.0 CONTROLLERS The major use of controllers is to detect errors in the variables and to create error correction messages that which is caused by the error. To complete this task the controller design must have an adjustable set point that can be comparison to the process variable. The error that is given is sent as a response for needed action to be carried out. The block diagram is given in Fig . The input could be as an input from the transmitter, which happens in the situation involving a receiver-controller. A three mode controller transfer function likely should be as given in the equation , the static gain has been resolved in two perspectives ; K is the nominal output and input spans and this would normally n=be unity for a receiver controller, and Kc is an adjustable measurement known as proportional gain. EQUATION. 2 The three modes stated above give the derivative, integral, and proportional modes respectively. FIG 2.6 Simpler controller designs employing one or two modes are often used. The basic combinations are P- Proportional only I- Integral only PI- proportional plus integral PD proportional plus derivative PID proportional plus integral plus derivative The transfer function may be derived from EQUATION. 2 by eliminating the appropriate terms. In the self operated regulator the actuator, controller and sensor are normally the same thing and with the same element. The controller has no other than the set point and has fixed gain and practically no adjustments. The transfer function is taken as: EQUATION. 3 Considering an example with a regulator with a set point of 5 psig and a flow capacity of 0.6, a temperature of 60 degree (Fahrenheit) and a pressure of 5 psig. The off set flow capacity will be 20 percent. The density can be determined with the use of the equation of state of a perfect gas as shown below: CALCULATION .1 LLOYD, SHELSON, G AND ANDERSON, GERALD, D. 1971. Industrial Control Process. Control Components .1st edn. Marshaltown, Iowa: Fisher Controls Co. pp. 115 – 148. 11.0 INPUT AND OUTPUT â€Å"This simple valve model has three states: OPEN, WORKING, and CLOSED. As the valve is the only component of the pressure-regulator that has state, the composite device, likewise, has only three states: [OPEN], [WORKING], and [CLOSED]. Suppose the input pressure is decreasing and the pressure-regulator is in state [WORKING], then dXFp = +, which causes A, the cross-sectional area available for flow to increase. This raises the possibility that A
