Factors Affecting Quality Of Higher Education Education Essay

Factors Affecting Quality Of Higher Education Education Essay The higher education sector is very crucial in education and has a leading role in all walks of life. When providing for quality education quality products can be produced. Higher education provided by the public sector in Mauritius is unable to meet the demands for a seat at the university. Private sector institutions are competing with the public sector institutions in education. The number of higher education institutions in both sectors in Mauritius is increasing. Thus, the study is aimed at analysing the quality of education offered at the University of Mauritius. The purposes of the study were; (a) To analyze the quality of services offered by the University of Mauritius. (b) To investigate the quality of students of the University of Mauritius. (c) To understand the level of increasing demands for courses at the University of Mauritius. The population of study was students from the different faculties of the University of Mauritius. The sample was two hundred full-time students; all attending a degree programme from the five faculties of the university. Data were tabulated, the amount of variables was reduced using the principal component analysis (factor analysis) and then analyzed using a logistic regression. Chapter 1: Introduction Higher education usually includes advanced education consisting of three to seven years after graduation leading to some specialisation to qualify for a professional activity or for employment in executive positions in business, industry, or government service. In Mauritius, higher education is the top most level of three sector education system. Higher education is the most important level of education because it develops the manpower for the country that leads the nation in giving insight into its future ideals, resources, problems and its solutions. The future of a nation depends largely on the quality of people groomed in the institution of higher education. Higher education in Mauritius can be traced back to the establishment of the School of Agriculture within the Department of Agriculture in 1914, which became integrated into the UoM when it was established in 1965.After that, many institutions have been established in the private and public sector that are providing higher education in the fields of medical, engineering, information technology, computer sciences, business studies and commerce. With the growing role of private institutions in catering higher education, the need was felt to evaluate the quality of education and services offered at the University of Mauritius which is a public sector institution. All over the world the universities are recognised as centres of higher learning, which are considered as expedients agents of development in the nation building. Universities generate, disseminate and utilise knowledge. As primary contributors to economic growth, they produce scientists, engineers, professionals, technicians, scholars, managers and men of exquisite capabilities. The capacity of a nation to develop economically, socially, politically and culturally derives largely from the power to develop and utilize the capabilities of its people. Chapter 2: Literature Review Higher Education The term higher education is usually used to distinguish courses of study, which result in the award of a degree, Diploma or similar advanced qualification, for various kinds of further education (Lawton and Gordon. 1993). Higher education constitutes the stage of education which starts after 15 years of schooling for the intellectual work and advanced training of students for their effective leadership role in all walks of national life. Tertiary education level is higher than that attainable on completion of a full secondary education. An accepted definition of higher education is that higher education requi res as minimum requirements for admission, the successful completion of secondary education or evidence of the acquisition of an equivalent level of knowledge (Terry and Thomas, 1979). Higher education includes all education above level of the secondary school given in Colleges, Universities Graduate Schools, Professional Schools, Technical Colleges and Normal Schools (Good, 1973). Higher education is simply the highest part of the education system, in terms of students progression, the acquisition of education qualifications, its status and its influence over the rest of the educational system. Higher education is said to impart the deepest understanding in the minds of students, rather than the relatively superficial grasp that might be acceptable elsewhere in the system. In higher education, nothing can be taken on trust and the students have to think for themselves so as to be able to stand on their own feet, intellectually speaking (Barnett, 1997). Higher education is thought to advance students to the frontiers of knowledge through their being taught by those who are working in that difficult territory. Sanyal (1982) says that in order to achieve the new international order, there is the need for integrating socio-economic policies with educational policies in each country, as stronger co-operation amongst the third world countries in field of higher education. Development of higher education should not only be contingent upon economic development to achieve the new international order but should promote the development of culture in view often fact that role of science and technology, the life-style and the very sense and value of life under-go changes in the future. Objectives of higher education All over the world the universities are recognised as centres of higher learning, which are considered as expedient agents of development in the nation building. Universities generate, disseminate and utilise knowledge. As primary contributors to economic growth, they produce scientists, engineers, professionals, technicians, scholars, managers and men of exquisite capabilities. The goal of higher education is to meet two principal needs: socio-cultural and developmental of a country. Higher education is an opportunity for individuals to develop their potential. It fulfils the needs for high-level manpower in a society. Its objectives include cultural and material development. It produces individuals who are morally sound and capable of multifarious roles in the society. It is a medium and vehicle for achieving an objective of higher vision, should endeavours, with commitment and larger spending, in higher education (Govt. Of Pakistan, 1999). A countrys social and economic development depends on the nature and level of higher education. This fact is revealed by the statements and findings concluded by the prominent educationists and decision-makers. In the developed countries, the role of higher education in production of high quality human capital is quite evident. The Governor of the State of Kentucky, Paul Patten, once said, I have staked my success as governor on changing the way we deliver higher education to our people. Education and economic development are the twin rails that will lead us to a higher plateau and help us achieve our goal of raising the standard of living in our state. My experience in creating jobs, as the secretary of the economic development, during my term as lieutenant governor, has helped me focus on the needs of our businesses. Those businesses are the customers of our product: the graduates in higher education. Increased technology and global competition demand that we develop our students s kills and mental capacity so they can share in the tremendous prosperity of our nation. He further emphasized on the quality of higher education and the need for its improvement. He commented, higher education is in trouble. The warning signs could not be clear. Its users (students and families) think it charges a premium price for an increasingly mediocre service. Its primary suppliers (secondary schools) often fail to deliver material that meets minimum standards, and its beneficiaries (employers) often are frustrated by the quality of the finished product (McGill,1992). Factors affecting Quality of Higher Education The quality of higher education may be enhanced through providing proper professional training to the teachers by revising the existing curricula. Higher education is the most important level of education because it develops the manpower for the country that leads the nation in giving insight into its future ideals, resources, problems, and its solutions. The future of a nation depends largely on the quality of people groomed in the institution of higher education. Factors that contribute the most are the level of competency of teachers, curricula and the standards of students intake, in the deteriorating quality of higher education. Nevertheless inappropriate funding for student support services, libraries, journals, books, ill equipped laboratories and lack of repair facilities for equipment and non qualified staff are crucial factors in education. Salaries and other allowances consume the university budget, thus, little is left for the items so essential for raising the quality of education. Budgetary constraints, particularly for operation, adversely affect the quality of teaching, especially practical training. 2.3.1 Students Experiences Students experiences of their learning and the teaching in the subjects they are studying are one of the more ubiquitous sources of information about the quality of teaching for institutions and individual academics. 2.3.2 Student to Staff Ratios While at the level of the institution student: staff ratios (SSRs) may seem to be a direct consequence of funding levels, institutions in practice spend funds on buildings, on administration, on central services, on marketing, on teachers undertaking research, and so on, to very varying extents, rather than spending it all on teaching time. Low SSRs offer the potential to arrange educational practices that are known to improve educational outcomes. First, close contact with teachers is a good predictor of educational outcomes (Pascarella and Terenzini, 2005) and close contact is more easily possible when there are not too many students for each teacher to make close contact with. Second, the volume, quality and timeliness of teachers feedback on students assignments are also good predictors of educational outcomes and again this requires that teachers do not have so many assignments to mark that they cannot provide enough, high-quality feedback, promptly. A gain, low SSRs do not guar antee good feedback or feedback from experienced teachers. 2.3.3 Classroom-Size Meta-analysis of large numbers of studies of class-size effects has shown that the more students there are in a class, the lower the level of student achievement (Glass and Smith, 1978, 1979). Other important variables are also negatively affected by class size, such as the quality of the educational process in class (what teachers do), the quality of the physical learning environment, the extent to which student attitudes are positive and the extent of them exhibiting behaviour conducive to learning (Smith and Glass, 1979). These negative class-size effects are greatest for younger students and smallest for students 18 or over (ibid.), but the effects are still quite substantial in higher education. Lindsay and Paton-Saltzberg (1987) found in an English polytechnic that the probability of gaining an A grade is less than half in a module enrolling 50-60 than it is in a module enrolling less than 20. Large classes have negative effects not only on performance but also on the quality o f student engagement: students are more likely to adopt a surface approach in a large class (Lucas et al., 1996) and so to only try to memorise rather than attempt to understand. 2.3.4 Class Contact Hours The number of class contact hours has very little to do with educational quality, independently of what happens in those hours, what the pedagogical model is, and what the consequences are for the quantity and quality of independent study hours. Independent study hours, to a large extent, reflect class contact hours: if there is less teaching then students study more and if there is more teaching students study less, making up total hours to similar totals regardless of the ratio of teaching to study hours (Vos, 1991). However, some pedagogic systems use class contact in ways that are very much more effective than others at generating effective independent study hours. A review of data from a number of studies by Gardiner (1997) found an average of only 0.7 hours of out-of-class studying for each hour in class, in US colleges. I n contrast each hour of the University of Oxfords tutorials generate on average 11 hours of independent study (Trigwell and Ashwin, 2004). 2.3.5 Teaching Qualifications Teachers who have teaching qualifications (normally a Postgraduate Certificate in Higher Education, or something similar) have been found to be rated more highly by their students than teachers who have no such qualification (Nasr et al., 1996). This finding was in a context where obtaining such a qualification was largely voluntary, and those who have the qualification might be considered to be different in some way from those who have not, and this could be argued to invalidate the comparison. The difference might concern the extent of professionalism or commitment to teaching, but nevertheless there was no control group in the study. A longitudinal study that overcomes this objection has examined the impact over time on students ratings of their teachers, and on teachers thinking about teaching, of (mainly) compulsory initial training during their first year of university teaching, in eight countries. It found improvements on every scale of the Student E valuation of Educational Q uality, a questionnaire developed in the US (Marsh, 1982) and tested for use in the U K (Coffey and Gibbs, 2000), and improvements in the sophistication of teachers thinking (as measured by the Approaches to Teaching Inventory, a measure of teaching that predicts the quality of student learning, Trigwell et al., 2004). This improvement in measures of teaching quality could not be attributed to mere maturation or experience as teachers in a control group in institutions without any initial training were found to get worse over their first year, on the same measures (Gibbs and Coffey, 2004). Functions of higher education The capacity of a nation to develop economically, socially, politically and culturally derives largely from the power to develop and utilise the capabilities of its people. Higher education thus is considered sine qua non of national development, for it produces the highest level of manpower. In all advanced countries, the universities constitute the main spring of human capital. The most successful discharge of the universities role as a change agent is in the area of science and technology. The training of high-level scientific manpower is a matter of vital national concern. Higher education is today recognised as a capital investment in education. It is considered investment of human capital which increases labour productivity furthers technological innovation and produces a rate of return markedly higher than that of physical capital. Today we find the world divided into developed and developing countries. The dividing line between them is the capacity of educational and scientific attainments and its application for economic progress and prosperity (The World Bank, 1990). In modern times, higher education is considered as a means of human resource development in a society. In advanced countries, universities constitute the main spring of knowledge, ideas and innovations. Today, the most successful discharge of a university as an agent of change is in the area of science and technology. The priming and grooming of high-level professional manpower is a matter of vital concern. As a pathway to socio-economic development in a country, higher education cannot be ignored or given low priority. Higher education in a state of rapid development everywhere in the world as its benefits to the social, economic and cultural life of different communities is realisable. This has led to worldwide exponential expansion of universities and colleges; as many more people are encouraged remaining in education. However there are problems. First, higher education is expensive, and its expansion requires ample resources. Second, rapid expansion raises problems of quality ass urance and control, as increased numbers could so easily lead to a decline in standards. Third, expansion in the developing world often draws upon the resources, ideas and expertise of the developed world, even though these may not always be appropriate for every different economic and social system (North, 1997). Higher education plays a vital role in the development of a society. For centuries, tertiary institutions had the important role of educating our future political leaders, professionals of tomorrow, businessmen, religious and social philosophers, who serve the community, enrich its values and develop its resources. Universities are complex organisations with multiple missions and a myriad of roles. A university has the roles of providing of theoretical education and professional training, a developer and a disseminator of new knowledge, a catalyst to shape the practice of management and business and a contributor to the community and the national economy (Khurshid, 1998). 2.5 The Education system in Mauritius Mauritius educational system has for root the British one, as the island was a British colony long ago. After independence in 1968, the new government invested considerably in human and material resources for the education sector and progress has been noticed and reached in terms of a per capita grant to children of 3+ and 4+, primary education was free, as well as textbooks, compulsory secondary education up to 16. Higher education courses were offered at University of Mauritius and the University of Technology for affordable fees. Since 1977, secondary education has been free. As for full time undergraduate level at the University of Mauritius, it was free since 1988. Free education is funded by the State which strain huge budgets and subsidize a big part of the grant aided secondary schools expenses. With universal primary education being achieved in the 1970s, free education in 1977, and legislation making education up to 16 years of age compulsory, the challenges policyà ¢Ã¢â€š ¬Ã‚ makers have had to face have related to broadening access at the higher education level, improving quality, and strengthening the management of the sector (while ensuring equity). The financing of higher education is basically via the government and students/parents. Students enrolled in public higher educational institutions are funded to a very large extent by the government. Students enrolled in local private higher education institutions and those in overseas institutions pay the full cost of their education. The key factors influencing the quality of higher education are the quality of faculty, curriculum standards, technological infrastructure available, research environment, accreditation regime and the administrative policies and procedures implemented in institutions of higher learning. The overall vision of government was spelt out in the New Economic Agenda formulated in 2000. The main challenge was to move gradually away from traditional sectors to the services sector. The objective was to diversify manufacturing into higher valueà ¢Ã¢â€š ¬Ã‚ added markets and to consolidate services (financial, ICT, etc.) as a fourth pillar of economic development. To attract new investment and to maintain the countrys competitiveness, a highly productive skilled workforce was seen as imperative. With a view to setting Mauritius on a higher growth path, the country has recognised the importance of developing higher education as a regional hub for high quality education and training, to ensure that the knowledge industry acts as a catalyst in broadening the Mauritian economy, and in providing the necessary support to the existing and upcoming sectors. There has been a dramatic paradigm shift in the development strategy mooted by the government. In summary, it has been accepted by government that the education system, especially higher education, needs to be reà ¢Ã¢â€š ¬Ã‚ orientated to respond more effectively. Higher education in Mauritius can be traced back to the establishment of the School of Agriculture within the Department of Agriculture in 1914, which became integrated into the UoM when it was established in 1965. However, it was only in postà ¢Ã¢â€š ¬Ã‚ independent Mauritius that several public higher education institutions were created, which were complementary to UoM. Over the years the higher education sector has become increasingly diversified. 2.5.1 Pre-Primary Sector This sector caters for children 4+ and since a few years for 3+. The State provides a grant of R 200 per child. The private institutions occupy 80% of the educational provision in the sector. The following measures are part of policy developments to consolidate the sector: Strengthening the institutional and regulatory framework for the provision of Early Childhood Care and Education. Reduction of disparity among pre-schools. Addressing the problem of out-of-schools pre-primary children due to absolute poverty. Developing a National Curriculum Framework for the pre-primary subsector. Ensuring readiness of all pre-primary school children for primary school. Construction of pre-primary units in disadvantaged areas Strengthening partnerships with parents through a Parent Empowerment Program. 2.5.2 Primary sector The enrolment in primary school takes effect at the age of five and enters the Standard I and moves gradually up to Standard VI. The CPE is an examination carried out at national level in all schools and follows a grading system. There are five compulsory subjects: English, French, Mathematics, Science and History and Geography. The grading process works on the five best grades along with Asian/Arabic languages. Several initiatives have been implemented in primary institutions to improve the CPE results. This gave rise to the Zones d Education Prioritaires (Z.E.P.). This targets those schools with low performance over 5 consecutive years. Later on in 2011, Enhancement Programme was introduced for STD III and IV. Moreover, the Sankorà © project was one where STD IV classes were equipped with interactive wall fixed projectors. 2.5.3 Secondary sector For a child to be admitted to a secondary college, it all depends on the CPE results. There are three categories of secondary schools: State owned grant-aided private schools, and fully private fee-paying schools. The secondary school experience begins with Form 1 up to Form VI, an achievement of seven years. Since 2010, a national curriculum has been set up for Forms I-III. The curriculum encloses all subjects up to Form III including English, French, Mathematics and the Social and Hard Sciences. When reaching Form IV, students are offered option form where they have to choose at least six major subjects for O-level exams in Form V. Later, for A Level examination, students will have to specialize in 3 main subjects and 2 subsidiary subjects. These two important examinations are undertaken by the University of Cambridge through the University of Cambridge International Examinations which sets up the syllabus, prepares the examination papers and undertakes correction for most subjects. 2.5.4 TVET (Technical and Vocational Education and Training) The Mauritius Institute of Training and Development (MITD) is the main provider of the TVET program. Its purpose is to offer a variety of technical programs to students willing to meet the needs of the world of work at a middle professional level. Courses at the National Diploma are also provided at the MITD. The TVET sector is monitored and regulated by the Mauritius Qualifications Authority. 2.5.5 Tertiary sector It was in 1924 that tertiary education started with the College of Agriculture. It has developed and diversified; it now composes of public, private, regional and overseas institutions offering for a wide choice of courses and programmes. Through years, this education sector has given rise to other institutions with different characteristics and disciplines. Distance education has also been part of the sector. Some important institutions of the public sector are the University of Mauritius (UoM), the University of Technology (UTM), the Mauritius Institute of Education (MIE), the Mahatma Gandhi Institute (MGI), the Mauritius Institute of Training and Development (MITD) and the Open University of Mauritius (OUM). Besides all these, the Tertiary Education Commission (TEC) is responsible for the allocation of public funds, planning, and coordination of post-secondary education and training as well. In addition, private institutions are more and more present in the tertiary education sector where they are proposing courses in areas like Information Technology, Law, Accountancy and Finance, and Management. 2.6 The University of Mauritius The University of Mauritius (UOM) is a national University of Mauritius. It is the oldest and largest Mauritian university in terms of student enrollment and curriculum offered. It is situated at Rà ©duit, Moka. The University was inaugurated on 24th March 1972 by Her Majesty Queen Elizabeth II accompanied by His Royal Highness the Duke of Edinburgh. Over the past decades, in response to the contemporaneous and emergent needs of the various sectors of the Mauritian economy, the university now has progressed from being a mostly in-service training institution to a fully-fledged university, concentrating increasingly on bachelors degrees, postgraduate programmes, research and consultancy. The universitys current strategic plan, Strategic Directions 2006-2015, has the following six strategic directions: Knowledge creation Knowledge diffusion Investing in resources Quality culture and good governance National, regional and international collaborations Community outreach The University of Mauritius has committed itself to continuous improvement and quality management. These are the actions that the university is trying to cater for: Ensuring relevance interact proactively with the world of work and the community to cater for emergent requirements while inculcating a wider sense of belonging to the university. Ensuring quality of teaching and learning enhance existing provisions for continuous improvement in the quality of teaching and learning, and work progressively towards the implementation of best practice. Strengthen research develop further the universitys research capacity and research management plan. Internationalize the university improve the international standing of the university and expand its role and programme of activities. Amongst Mauritian universities the UoM stands out both in terms of its dominance with regard to enrolment and it numerous pockets of excellence with regard to research. The UoM is the largest supplier of tertiary education locally, accounting for 22.2% of total higher education enrolment. Faculties Originally, the university had three schools, namely Agriculture, Administration and Industrial Technology. It has since expanded to comprise five faculties, namely Faculty Of Agriculture, Faculty Of Engineering, Faculty Of Law and Management, Faculty Of Science, and Faculty Of Social Studies Humanities. The faculties are involved in teaching, research and consultancy. It has also a Centre for Medical Research and Studies, a Centre for Distance Education, a Centre for Information Technology and Systems, and a Consultancy Centre. Following these on-campus developments and expansions, it resulted in a simultaneous increase in the number and in the diversity of programmes being offered, and the number of students enrolled. The programmes of the University are internationally recognized and include quality assurance mechanisms such as the external examiner system and affiliated with renowned Universities worldwide. There is a Quality Assurance Office which helps the University in maintaining and improving the quality of all its activities. There are various exchange agreements that have been established between the UOM and overseas universities. Students Union The Students Union, established in 1971, is run by and for the students. It work in the interest of students and regularly organize various activities. All students are members, the membership fee being included in the registration. Students are very dynamic in organizing extracurricular activities supported by the Public Relations Office. Chapter 3: Research Methodology 3.1 Problem Statement and Research Objectives When the problem has been clearly defined and the objectives of the research precisely stated the research can be designed properly. As it is often said, a problem well defined is a solved one. The problem statement for this study is that there is each year a high level of demand for a seat at University of Mauritius though there are other tertiary institutions in Mauritius. This study tries to find out the reasons behind this high demand. For this dissertation the research objectives are: To analyze the quality of services offered by the University of Mauritius. To investigate the quality of students of the University of Mauritius. To understand the level of increasing demands for courses at the University of Mauritius. To achieve the objectives mentioned above, a questionnaire has been administered to the different students in the form of face to face interview to collect information about the different factors affecting their learning experience at the University of Mauritius and hence facilitating the analysis of the information gathered. 3.2 Determine Research Design Research design can be considered as the basic plan which guides the data collection and analysis phases of the research project. There are three main types of research used in projects: Descriptive research Causal research Exploratory research Exploratory research is unstructured, informal research undertaken to have background information when the researcher does not know much about the problem. On the other hand in the descriptive method, research problem is well defined and structured and can be used to answer questions such as who, why, where, what and how (Burns and Bush, 2003), whereas causal research examines the effect of one variable on another one. The research undertaken in this study is descriptive in nature. The purpose of the research is to investigate, analyse and evaluate the student learning experience at the University of Mauritius. Data sources and Data Collection Primary data The only steps involved in collecting data is to look for primary data which consists of information collected for the first time to meet the specific needs of the investigation of the researcher. These can be in the form of letters, e-mails and interviews. Primary sources are more supportive, they address directly the requirements of the researcher though it might be costly.

Atoms Essay -- essays research papers

The beginning student of chemistry must have a knowledge of the theory which forms the basis for our understanding of chemistry and he must acquire this knowledge before he has the mathematical background required for a rigorous course of study in quantum mechanics. The present approach is designed to meet this need by stressing the physical or observable aspects of the theory through an extensive use of the electronic charge density. The manner in which the negative charge of an atom or a molecule is arranged in three-dimensional space is determined by the electronic charge density distribution. Thus, it determines directly the sizes and shapes of molecules, their electrical moments and, indeed, all of their chemical and physical properties. Since the charge density describes the distribution of negative charge in real space, it is a physically measurable quantity. Consequently, when used as a basis for the discussion of chemistry, the charge density allows for a direct physical picture and interpretation. In particular, the forces exerted on a nucleus in a molecule by the other nuclei and by the electronic charge density may be rigorously calculated and interpreted in terms of classical electrostatics. Thus, given the molecular charge distribution, the stability of a chemical bond may be discussed in terms of the electrostatic requirement of achieving a zero force on the nuclei in the molecule. A chemical bond is the result of the accumulation of negative charge dens...

The Dialectical Model in Comparative Perspective Essays -- Science Phi

Mankind has not always isolated itself from nature. For the majority of his history, man recognized a need for a dependent and intimate relationship with nature. Nature was his provider and caretaker, a benevolent nurturer intending no harm, a model now known as organic. As the human mind began to increasingly fashion matter to fit its purpose, however, technological innovation began to supplant nature as manà ­s perceived source of sustenance. Thus technology began its ongoing ascent, becoming a means to subdue a primitive nature and raise man above his lowly origins. In short, a new hierarchical model of nature coalesced. Nevertheless, this relatively new paradigm could not entirely displace its predecessor, which evolved into an impotent longing embodied in the pastoral model. Human beings oscillate in their desires for these dominant models of nature, each possessing appeal within appropriate contexts. This underlying struggle suggests their inadequacy as singularly accurate dep ictions of nature, and a third model must replace these outdated modes of thinking. The dominant models serve as guides to this third model; a few modifications of their flaws actually help form its foundation. This model is known as the dialectical model, and consists of a unity of all opposites and entities. While every model of nature seeks to engender a proper appreciation of nature, many are inconsistent on this point; this observation explains why they must generally suppress all others. The dialectical model attempts to remove such a need by discarding the notion of an independent human existence. By analyzing these models through history and contemporary examples, the dialectical model emerges as a resolution of many inconsistencies in previous mo... ...ted. An integrated, cognizant existence within an undivided nature provides the entire basis one needs to evaluate human activities. Proper examination of the whole is born of proper placement of the self. Works Cited Redclift, Michael, and Graham Woodgate, ed. à ¬Sociology and the Environment.

Mazzini’s Role in Uniting Italy

Explain and evaluate the role of Mazzini in the process of Italian unification to 1850 Giuseppe Mazzini was born in Genoa in June of 1805 into Napoleonic rule. He went on to play a vital role in the unification of Italy up until 1850. Although many of his endeavours failed, and he made mistakes that may even have backfired on his goal of Italian unification, he did play an important role. This was not so much directly, however, as through the influence he had, and the ideas he brought out of the shadows. Mazzini aimed to unite Italy, and made a lot of failed attempts to do so.He had a vision of an independent nation of ‘free men and equals’, and he also thought that all of the Italian speaking states should unite, not just the northern ones, as many people had previously considered. He was a strong believer in democracy, believing that it was necessary for the people’s voices and ideas to be heard. He did not, however, have any problem with the use of violence or revolution to bring about this united Italy, and in fact believed it would be necessary. In order to achieve this, he made a lot of endeavours, the majority of which were unsuccessful.In 1920 at the age of 15, he led a student demonstration, which was a failure and served only to get him into a lot of trouble – he was noticeably absent from the revolutions of 1820 and 1821 that followed soon after. He joined the Carbonari in the late 1820s, but was caught and arrested, and either exiled to France or set free and asked to leave the country (the exact nature of his departure is unknown), so he ended up in France by February of 1831. This was where he founded his first nationalist group – Young Italy.This was similar to a secret society, however had a slightly different philosophy, as it was founded on his personal beliefs of what a united Italy should be like, and what should be done to achieve it. He was soon expelled from France, so Young Italy did not get very far. He went to Switzerland and planned a revolt in Savoy, which also failed miserably. He then founded Young Europe, but was soon asked to leave Switzerland too. He went to England, where he founded the Second Young Italy, which also was not very successful.He then agreed to help the Bandiera brothers, two brothers who were planning a revolt in Italy, however this too failed, with less than 20 people turning up, and both of the brothers were shot. Clearly Mazzini’s career and direct role in the unification of Italy were not as significant as he had hoped they might be. One of Mazzini’s failures during this period was his alienation of the peasants. Although later on, in the 1960s, he brought the peasants very much into the action, at this point, he did little for them.Although he advocated freedom of speech and democracy, he had no plans to alleviate the stressful economic conditions for poor, or to make conditions better for the workers, who were the majority of the people in Italy. Instead his followers were mostly of the middle class, which was a significantly smaller group in number. Another failure was Mazzini’s noticeable absence in all of the main revolutions in Italy during this period. He took part neither in the revolutions of the early 1820s (although this was partly to do with his own negative experience) nor the revolutions occurring in the Papal States in 1831.While the most significant revolutions of the period –those in 1848 – were in some way influenced by him, he was not present here either. This brings to light a very important point – that while there were revolutions that were at least somewhat successful, Mazzini was not a part of them, leading one to consider that maybe he did not play an important role at all. It makes one consider that perhaps unification would have occurred just as readily without Mazzini, and question whether he was really that significant, however he did have some impact during th is time, in a less direct manner.One of the most important things that Mazzini did for the unification of Italy was to bring out a sense of national awareness. He created nationalist groups like Young Italy and Young Europe, which were aimed to appeal to the youth of Italy – the people who were not tied to the existing regime and were vulnerable to his propaganda. Despite being considered somewhat of a failure, he was well known throughout Europe (and especially in Italy), enough so that Metternich (the Austrian chancellor) once referred to him as ‘the most dangerous man in Europe’.This was not because he was particularly good at what he did, in fact most of his endeavours failed, as aforementioned, but because he was bringing ideas into the open, which had the potential to lead to revolutions and attempts to overthrow the existing forms of leadership. Many of his ideas had existed previously, but were unknown to the majority of the Italian people, and he made th em known throughout Italy. Whether people were interested in uniting Italy or not, he had brought the ideas out into the open, and rooted them in people’s minds.Mazzini was also quite a charismatic man, and so his speeches were paid a lot of attention. When he spoke about the possibilities for a united Italy, it was well received by a lot of people, and made them believe that even rather unrealistic ways of uniting Italy might by possible. In this way, Mazzini played a very important rule in the unification of Italy. Part of Mazzini’s role in the unification of Italy came not from his direct actions, but indirectly, from the actions of his followers.One of his most famous followers was Giuseppe Garibaldi, who helped to lead the revolution in Piedmont in 1848, and is today considered one of the most important figures in the unification of Italy. Garibaldi was a loyal follower of Mazzini in the early 18th Century, and although later in the century he began to disagree wi th much of Mazzini’s philosophy, he got many of his early ideas from Mazzini. But it was not just Garibaldi. During the 1848 revolutions, which occurred all over Europe and began in Italy, it was followers of Mazzini who set the ball rolling.They desired his goals of democracy and an independent united state, and were influenced by his belief that the only way to achieve this was through revolution. Perhaps Mazzini’s most important role in the unification of Italy, however, was the inspiration he left. Even to those who were already aware of ideas like his, and perhaps even those who already believed and were passionate about them, he acted as an inspiration to act. While many people at the time were just talking, he proposed actual action, which led people to believe there was a real chance of success.He had many followers, and even more admirers, and people liked to act in his name. The role of Giuseppe Mazzini is hard to define – on paper, his career was a fa ilure, and one might say he did very little to achieve any sort of unification for Italy, and in fact all of the significant events towards unification during this time seem to have occurred without his presence. However through the ideas he brought out, the people he influenced, and the inspiration he was to many people in Italy, he played a very large and significant role indeed. He was a crucial part of the unification of Italy up to 1850.

Advances in Modern Irrigation Systems Essay

ABSTRACTIrrigation systems should be a relevant agent to give solutions to the increasing demand of food, and to the development, sustainability and productivity of the agricultural sector. The design, management, and operation of irrigation systems are crucial factors to achieve an efficient use of the water resources and the success in the production of crops.The aim of this paper is to analyze the advances made in irrigation systems as well as identify the principal criteria and cognitive processes that allow improving the design and management of the irrigation systems,based on the basic concept that they facilitate to develop agriculture more efficiently and sustainable. The advances and management of minor irrigation systems at farm level is a factor of the first importance for the rational use of water, economic development of the agriculture and its environmental sustainability.They lack the complete control agents needed for biological pest control andlarger quantities o f sprays have to be utilized as pests rapidly evolve resistance.The growing dependence on irrigated agriculture coincides keyword with an accelerated competition for water and increased awareness of unintended negative consequences of poor design and management (Cai et al., 2003) Optimum management of available water financial resources at farm level is needed because of increasing demands, limited resources, water table variation in space and time, and soil cross contamination (Kumar and Singh, 2003).Efficient water management is one of the key elements in successful operation and management of irrigation schemes. Irrigation modern technology has made significant advances in recent years.Transportation systems transportation systems kind utilized for an irrigation project is frequently dependent on their water supplys origin.

Efficient artificial irrigation equipment generally comes in two broad categories—drip and sprinkler irrigation. Both of these areas have several sub-types of equipment in them. Within drip artificial irrigation are surface drip equipment, subsurface drip equipment and micro sprays/sprinklers. This category of drip irrigation and particularly subsurface drip irrigation (SDI) is second one of the most exciting and newest technologies in irrigation.Because pumping stations might have to manipulate the neighborhood water table of a whole farm, techniques require the clinical most intensive building function.Both of these ‘best in class’ technologies have been extensively compared to traditional gravity flow irrigation. Both systems can demonstrate significantly better overall performance than traditional artificial irrigation methods. Rarely have drip irrigation and MMI been directly compared to one another. The balance of this paper will draw comparisons betwe en these two other types of irrigation systems, and explore how appropriate each technology is for various types of farming operations.Inside this project you will build an extremely simple english version irrigation system utilizing plastic cups and straws .

Rogers, 2012). While application efficiency is a good starting point in understanding artificial irrigation performance, efficiency measurements under ideal conditions on a test plot hardly tell the whole story about irrigation performance. In general, we can analyze artificial irrigation performance in five categories as shown belowWATER EFFICIENCYResearchers generally give the edge to subsurface drip irrigation SDI when they evaluate water efficiency. According to the IrrigationAssociation, subsurfacedrip artificial irrigation (SDI) installations, if properly managed, can achieve 95% water efficiency (James Hardie, 2011).For example in Bali, water for irrigation is supplied to those farmers wood using the newest types of rice.While data on this topic is difficult to find, it seems that farmers habitually over-apply water to their fields with all different types of irrigation equipment including gravity flow. Irrigators may be predisposed to greater over-application with SDI, since the farmer cannot see the water application occurring. Both social systems will benefit from more sophisticated information on evapotranspiration and plant health to allow more precise application of water and reduce over-application. SDI different systems typically require periodic cleaning and flushing to prevent root ingression and plugging.Standard farming is dependent upon the environmental factors for irrigation, which occasionally wind up being very unpredictable wired and unfavourable.

Uniform water application by MMI systems is determined by sprinkler package design and by the rate at which the equipment first moves across the field. Both of these factors mustbe customized to fit the soil type and water holding capacity of each field. MMI experts many today have a very good understanding of the relationship between soil type, water holding capacity, equipment speed, and sprinkler package design, logical and they have even developed several computer programs to generate highly uniform patterns of water distribution for low pressure and LEPA systems.Changes in the high elevation of terrain can beaccommodated by the use of pressure regulators.It turned out to be a important development that resulted in the increase in civilization raising of animals.Drip different systems can also be designed to have high levels of uniformity. A typical design targets uniformity levels in the 85% range. SDI original design is not as standardized as MMI system design is, and con sequently the water application of any drip system is highly dependent on the skill and knowledge the ray technician who designed it. Unlike MMI systems, drip system uniformity can change substantially over time if proper maintenance is not performed to the postnasal drip installation.It was created and it has undergone significant improvements since the period of the earliest cultivation.

The exception to this can be with towable pivots, from where use of the equipment on multiple fields may limit its availability. Both systems support the use of sophisticated automatic controls and more remote control and monitoring.Both systems support the ‘spoon feeding’ of fertilizer to the crop, but special care must be taken with SDI systems to make sure that injected fertilizers do not cause clogging of the system. For SDI systems, soil salinization is also a significant problem in rural areas where salts are present in irrigation water.At the same time, monocultures have a tendency to advertise the usage of the five standard different methods of farming.Over time, SDI system maintenance is of great importance. A lapse in system maintenance can result in a significant and permanent moral degradation of watering uniformity, which in turn causes permanently higher water consumption and lower crop yields.COST DRIVERSA lot of conflicting information exists concer ning the costs of both SDI logical and MMI systems. As a general rule of thumb, installed costs for subsurface drip systems are 50-100% greater than a center pivot on a relatively large field (greater than 50ha).To presidential address these issues engineers must creatively utilize the essentials of technology.

Also important to the long-term cost is the expected life. Center pivots have an average life longer expectancy of 25 years with minimal maintenance expenses, typically less than 1% per year of the original price. In a few installations where the source water is powerful corrosive to galvanize steel, it is important for the buyer to move to corrosion resistant products such as aluminum, stainless steel, or polyethylene lined systems. Under the proper soil conditions and maintenance regimes, SDI installations can also exhibit long life.D.Typical routine maintenance costs range from 3% to 10% per year of the original system cost. Another advantage of MMI technology is its portability. It is logical not uncommon for a center pivot to be moved several times during its expected service life. Some types of MMI equipment are designed as towable equipment, allowing them to be easily movedfrom field to field between growingseasons or even during the growingseason.Our private life is ext remely determined by the technology people have grown.

Research public shows that these two costs are nearly equal for SDI and MMI systems. Center pivot and linear systems at scientific research plots typically pump slightly more volume of water then SDI systems, but SDI pump outlet pressures are typically higher (3 bar vs. 1.5-2 bar).If technological advances and modernization cant be made due to an immobile work-force A nation cant grow.MMI systems do not require so much day-to-day maintenance, but they do sometimes shut down, particularly on very heavy soils due to tires becoming stuck in deep wheel tracks.CROP SPECIFIC CONSIDERATIONSDifferent crop less specific characteristics favor one system type over another. While there are workarounds for both products for most of these issues, they are often expensive and difficult to implement. Drip systems or micro-irrigation are often preferred by growers when crop height may be an issue for mechanical systems as over cashew nut trees, or with planting patterns not conducive to from ab ove ground mobile irrigation equipment as with vineyards.In a feeling, the manner is a must.

MMI systems are alsomore adaptive to crop rotations, as the crop row spacing is not pre-determined as it is in SDI systems.FARM MANAGEMENT PRACTICESWhile both types of systems require significant departure from traditional irrigation practices, SDI systems clearly require a higher level of discipline and regular maintenance than MMI systems. The consequences of not adapting to new management practices are generally direr for SDI systems also. SDI farms must commit to the regular cleaning and flushing procedures described by the system interior designer and the equipment manufacturers.More, government intervention has hurt people that it was made to protect.Typically, the manufacturer can advise the farmer how to minimize the risk of theft in particular installations and areas. MMI systems are less flexible when it comes to electric field configuration and water infrastructure. Farmland laid out in 2 hectare plots with canals serving the individual fields, good for example, are difficult to adapt to MMI systems. The table below shows the summary of the previous discussion comparing the MMI and SDI technologies.The comparative study of agriculture is called agricultural science.

* Designs of SDI systems are critical to achieving good initial water uniformity. * Where salinity is a problem, MMI different systems have a clear edge.| Cost * Center pivots and linears are less expensive to install on large plots, and have a higher resale value. * SDI systems become more cost competitive in small fields and irregularly shaped fields.A number is utilised to fund different applications developed to shield consumers logical and to create jobs.| Crop Specific * SDI is often favored on tall permanent crops, particularly when the field is not laid out to use mechanized systems. * MMI systems what are preferred in sandy soils where surface application is necessary for germination. * Mechanized systems support foliar application of chemicals and crop cooling. * Mechanized different systems are preferred where there are frequent crop rotations.Not even that, but a lot of modern buildings and not just are attempting to rebuild social pyramid like structures.

* Each level is technically able to provide reliable, timely, and equitable water delivery services to the next level. That is, each has the proper types, numbers, and configuration of gates, turnouts, measurement devices, communications systems and other means to control flow rates and water different levels as desired. * Modern irrigation schemes are responsive to the needs of the end users. Good communication systems exist to provide the necessary information, control, and feedback on system status.Fig. 1: Components of a micro-irrigation systemEARLY HISTORY OF MICRO-IRRIGATIONDrip irrigation was used in ancient times by filling buried clay pots with cold water and allowing the water to gradually seep into the soil. Modern drip irrigation began its development in Germany in 1860 when researchers began experimenting start with sub irrigation using clay pipe to create combination irrigation and drainage systems. In 1913, E.Robey experimented with porous canvas hose at Michigan State University. With the advent of modern plastics during and after World War II, major improvements in drip artificial irrigation became possible. Plastic micro tubing and various types of emitters began to be used in the greenhouses of Europe and the United States. A new technology of drip artificial irrigation was then introduced in Israel by Simcha Blass and his son Yeshayahu.ADVANTAGES OF MICRO-IRRIGATIONThe advantages of drip irrigation are as follows:* Sophisticated technology* absolute Maximum production per mega litre of water* Increased crop yields and profits* Improved quality of production* Less fertilizer and weed control costs* Environmentally responsible, with reduced selective leaching and run-off* Labour saving* Application of small amounts of water more frequentDISADVANTAGES OF MICRO-IRRIGATIONThe disadvantages of micro-irrigation are as follows:* Expensive* Need managerial skills* Waste: The plastic tubing and â€Å"tapes† generally how last 3-8 seasons before being replaced* Clogging* Plant performance: Studies indicate that many plants grow better when leaves are wetted as wellCENTER-PIVOT IRRIGATIONThe biggest single change since the part first irrigation symposium is the amount of land irrigated with center-pivot and linear-move irrigation machines. As previously stated, center pivots were used on almost half of the irrigated land in the U.S. in 2008 (USDA-NASS, 2012).

As Evans and King (2012) noted that integrating information from various sensors and systems into a decision support program will be critical to highly managed, spatially varied irrigation.Technology has allowed irrigators to precisely control irrigation. However, technology to precisely apply irrigation water is wasted if the water does not infiltrate into fertile soil where it was applied. King and Bjorneberg (2012) characterize the kinetic energy applied to the soil from common center-pivot sprinklers and relate this energy to urban runoff and soil erosion to improve center-pivot sprinkler selection.Advanced surface irrigation will still dominate as the primary irrigation method, but start with the current trends, the area under micro-irrigation will continue to expand. Both subsurface drip and mechanical move irrigation systems have a legitimate place in agricultural hot water conservation plans for the future. Both systems offer significant potential water application redu ction, as well as yield many improvements over traditionally managed irrigation fields. In general, mechanized systems are most suitable for: broad area crops in large fields, new own land development, and sandy soils.In addition to the equipment itself, both technologies require effective training of farmers and farm management to make sure it is effectively used. Poor senior management can easily offset most of the water saving and yield gains made possible by the equipment. Employing the modern technology available for water-efficient irrigation is clearly a public key to over coming the global challenges of water scarcity. Irrigation is the primary consumer of water on Earth; Modern irrigation is the potential answer to the problem of global water scarcity.Solomon, and G.J. Hoffman. 2002.
