O objeto deste trabalho é a análise do aproveitamento múltiplo do reservatório de Barra Bonita, localizado na confluência entre os rios Piracicaba e Tietê, no estado de São Paulo e pertencente ao chamado sistema Tietê-Paraná. Será realizada a otimização da operação do reservatório, através de programação linear, com o objetivo de aumentar a geração de energia elétrica, através da maximização da vazão turbinada. Em seguida, a partir dos resultados da otimização da geração de energia, serão utilizadas técnicas de simulação computacional, para se obter índices de desempenho conhecidos como confiabilidade, resiliência e vulnerabilidade, além de outros fornecidos pelo próprio modelo de simulação a ser utilizado. Estes índices auxiliam a avaliação da freqüência, magnitude e duração dos possíveis conflitos existentes. Serão analisados os possíveis conflitos entre a navegação, o armazenamento no reservatório, a geração de energia e a ocorrência de enchentes na cidade de Barra Bonita, localizada a jusante da barragem. / The aim of this study is to analyze the multiple use of the Barra Bonita reservoir, which is located in the confluence of the Piracicaba river and the Tietê river, in the state of São Paulo, and belongs to the called Tietê-Paraná system. The reservoir operation will be optimized, through linear programming, aiming to increase the hydropower generation, by maximizing the water flow through turbines. In sequence, on the hydropower generation optimization results, computer simulation techniques will be used, in order to obtain performance rates as reliability, resilience and vulnerability, in addiction to other rates provided by the simulation model itself. These rates can assist to evaluate the frequency, the magnitude and the duration of possible conflicts that may occur. The navigation, the water storage in the reservoir, the hydropower generation and the occurrence of floods in Barra Bonita, a city located downstream the dam, will be analyzed.

This study consisted of bibliographic research based on documents produced by the World Bank and Unesco, and official documents of Brazilian Ministry of Education. The analyses and conclusions presented in this work were made by several authors, such as Dermeval Saviani, Gaudêncio Frigotto, José Carlos Libâneo, Yves Lenoir, Olinda Evangelista, Eneida Shiroma, Roberto Leher, António Nóvoa and José Gimeno Sacristan. In the course of the research, connections between the guidelines of international organizations, neoliberalism and globalization movement, and their consequences in the formulation of educational policies, especially in emerging countries were found. Thus, the definition of educational purposes is subordinated to the process of internationalization of educational policies in which education is tied exclusively to the interests of the economy and the market.The sense of quality in education is related, thereby, to the criteria of effectiveness of globalized market. From the analysis of the documents and with the support of other researches on the subject on focus, it was possible to verify that one of the role of public policies for education is to enable the insertion of population socially vulnerable to the labor market. To this end, programs for the poverty reduction are instituted, a result-based knowledge and skills curriculum that aims an incorporation of the less favored classes in society. Thus, such educational purposes, once incorporated into educational policies, school education planning, curricula, school functioning, and teachers' work, project a utilitarian sense of quality, restricted to the satisfaction of immediate, distant needs, far from the sense of social and cultural quality, aiming human emancipation. / Esta dissertação teve como objetivo analisar as finalidades educativas escolares em documentos que definem políticas e diretrizes da educação nacional em suas ligações com orientações doutrinárias e estratégicas de organismos internacionais, principalmente o Banco Mundial e a Unesco, visando apreender seu impacto na qualidade social do ensino. O estudo consistiu de pesquisa bibliográfica com base em documentos produzidos pelo Banco Mundial e Unesco, e documentos oficiais do Ministério da Educação. As análises e conclusões foram em diversos autores como Dermeval Saviani, Gaudêncio Frigotto, José Carlos Libâneo, Yves Lenoir, Olinda Evangelista, Eneida Shiroma, Roberto Leher, António Nóvoa, José Gimeno Sacristan. No percurso da pesquisa, foram constatadas conexões entre as orientações dos organismos internacionais, o neoliberalismo e o movimento da globalização, e suas consequências na formulação de políticas educacionais, principalmente de países emergentes. Desse modo, a definição de finalidades educativas subordina-se ao processo de internacionalização de políticas educacionais no qual a educação encontra-se atrelada exclusivamente a interesses da economia e do mercado. O sentido de qualidade da educação prende-se, assim, aos critérios de eficácia do mercado globalizado. A partir da análise dos documentos e com o suporte de outras pesquisas sobre o tema, foi possível constatar que as políticas públicas para a educação têm o papel de possibilitar a inserção de populações socialmente vulneráveis ao mercado de trabalho. Para isso, instituem-se programas de redução da pobreza, um currículo de conhecimentos e habilidades baseado em resultados visando incorporação social das classes menos favorecidas. Desse modo, tais finalidades educativas, uma vez incorporadas nas políticas educacionais, no planejamento da educação escolar, nos currículos, nas formas de funcionamento das escolas e no trabalho dos professores, projetam um sentido utilitário de qualidade, restrito à satisfação de necessidades imediatas, distante do sentido de qualidade social e cultural visando a emancipação humana.

The purpose of this study was to explore the perceptions of the essay writing process of first year undergraduates at Chancellor College (University of Malawi) and to a lesser extent those of the lecturers responsible for teaching academic skills. A mixed methods design, combining qualitative and quantitative techniques, was employed in order to obtain richer data for deeper understanding of the students’ writing process. Two hundred students from the humanities and social science faculties responded to a self-completion questionnaire towards the end of semester one. Based on the students’ responses, an open-ended questionnaire was administered to four full time English for Academic Purposes (EAP) instructors. Findings from this study indicate that most students find it very challenging to obtain sufficient and relevant source text information, paraphrase or summarise information, and use an appropriate academic writing style. As solutions to these challenges, the students suggested the need for timely essay writing instruction, availability of resources for essay writing, increased amount of time spent on essay writing instruction, and discipline specific instruction in essay writing. EAP instructors identified lack of teaching and learning materials, large EAP classes, and students’ negative attitude towards the EAP course, as some of the challenges they encounter when teaching the course. The EAP instructors proposed an increase in the number of staff members, making students aware of the significance of the EAP course at an early stage, and the availability of up to date resources, as some of the ways in which the teaching of the course can be improved. Overall, the findings seem to suggest that difficulties that students encounter during the writing process and teaching challenges that EAP instructors face, have great impact on students’ perception of academic writing as well as their approach to writing tasks. The findings also suggest a lack of dialogue between the students and their lecturers. This is evident in students’ unawareness of the nature of the writing demands of their lecturers and disciplines; students’ desire to have timely essay writing instruction; and the lecturers’ concerns about students’ negative attitude towards the EAP course.

The main purpose of this study was to examine the effects of strategy training in small group work on the reading comprehension of academic texts in English by Thai English as a Foreign Language (EFL) students. The strategy-training used was the Reciprocal Teaching Procedure (RTF) which focused on the four reading comprehension strategies: predicting, clarifying, questioning and summarizing. The research study was an experimental one using a single group design. The participants were thirty-four first year students enrolled in the English for Academic Purposes (EAP) program at a tertiary institution in the northeastern part of Thailand. Both quantitative and qualitative research methods were used. The pre-, post- and follow-up reading tests were employed for quantitative analysis. The students' performances were analyzed for statistically significant differences immediately at the end of the ten-week training and in the follow-up test eight weeks after the training. Qualitative data were collected from students' pre-, post- and follow-up questionnaires, checklists and journals, teacher's checklists and journal, and independent observer's checklists and field notes.

As a result of the development in foreign trade in Vietnam, there is a growing need for trained business executives and business people. A good command of spoken English is one of the most important qualifications of a foreign trade executive who needs English as a means of communicating with English speaking people in various business activities. At present, the responsibility for training students of commerce mainly rests with Hanoi Foreign Trade College. English language teaching in general, and the teaching of speaking skills in particular still leave much,to be desired. The students' oral proficiency is far from satisfactory. The purpose of this report is to explore the two main problematic areas in teaching speaking skills to students of commerce in Vietnam: syllabus design and teaching methods. The report consists of four chapters. Chapter one looks at some major theoretical problems and practical issues in English for Specific Purposes teaching. Chapter two provides an analysis of the teaching and learning situations at Hanoi Foreign Trade College and problems in teaching oral skills. Chapter three is mainly concerned with designing a communicative syllabus for the teaching of speaking skills to students of commerce. Chapter four deals with the theoretical assumptions and processes involved in oral communication and discusses some classroom methods and techniques in the light of the current communicative approach. This report should be regarded as an exploratory attempt in adopting the communicative approach to teaching oral skills to students of commerce in Vietnam.

The increasing number of economic and cultural aid programmes for Vietnam to reconstruct its war-torn economy in recent years from the United Nations Development Programme and other international and governmental organizations has created a great demand for English language teaching and learning in Vietnam. The language problems that face Vietnamese scientists and technicians working in these aid programmes have been a major concern of many educational institutions in Vietnam and a reason for the author of this Study Report to take up this study. Chapter one of this study covers major stages of development of the teaching of English for Specific Purposes (ESP) and various factors that influence the teaching of ESP. Chapter two discusses some current issues in the teaching of ESP in Vietnam with special reference to course organization, syllabus and material design at the Hanoi Foreign Language College. It also points out some misunderstanding and misconception in the teaching of English to Vietnamese scientists and technicians. Chapter three looks at major language problems that Vietnamese students meet when they go to study at different colleges or universities in English speaking countries. A close investigation will be carried out over a number of Vietnamese veterinary doctors studying at the university of Queensland in Australia. Chapter four is concerned with the selection of suitable syllabus models for ESP/EAP courses at HFLC and also attempts to work out appropriate syllabuses for EAP courses for Vietnamese students going to study overseas. The final chapter suggests some further considerations for organizing ESP/EAP courses at HFLC especially for material production, ESP teacher training and ESP testing. It is hoped that this Study Report will give language teachers in the ESP Department at the Hanoi Foreign Languages College a clearer picture of what ESP is all about and provide some guidelines for successful organization of teaching ESP and EAP to Vietnamese students.

Thesis (Ph.D. (English))--North-West University, Potchefstroom Campus, 2007.

The purpose of this study was to examine the English language needs of Tour Guidance students of Faculty of Applied Sciences at BaSkent University by referring to the perceptions of students, English instructors and curriculum coordinators and to see whether there was a relationship between students&amp / #8217 / attitude towards English language and their self ratings of learning and target needs. The data collection instruments used for the study were the attitude scale and student needs assessment questionnaire administered to forty-five students, ESP Identification Form administered to two curriculum coordinators and English Instructor Questionnaire administered to both of the curriculum coordinators and the three English instructors. The descriptive analysis of the data revealed that there were both similarities and differences among the perceptions of students, English instructors and curriculum coordinators with respect to the learning needs and target needs of students. Paired-Samples T Test results indicated need for most of the skills referring to learning and target needs. The relationship between students&amp / #8217 / attitude towards English language and their self ratings of learning and target needs came up to be of different values for the seven subdimensions of attitude. On the basis of the results of the study, it is suggested that speaking, listening and specialist vocabulary be emphasised more in order to fulfill the ESP needs of Tour Guidance students. Applying skill based syllabus as primary and situational and content approaches to syllabus design as subordinate is suggested to be effective as well. Using instructional materials appealing to the subdimensions of attitude is another suggestion presented.

A certain amount of water is required for a mine site located in Turgutlu in Western Turkey to be used in mining processes. The purpose of this study is to assess the impacts associated with meeting water supply requirements for the mine. Scope of the study involves determination of the alternative water resources, the assessment of impacts associated with each resource and the selection of the most feasible alternative in the aspect of environmental and technical effects. Three alternatives suggested to supply mine process water are surface water, groundwater and reuse of waste water of Turgutlu town after treatment. A low flow analysis of Gediz River was conducted for the evaluation of the surface water. For the groundwater alternative, Turgutlu-Salihli aquifer model was established using MODFLOW 2009.1 software and the impacts on groundwater resources were evaluated. The evaluation of the last alternative, reuse of waste water of Turgutlu after treatment, was based upon the amount of waste water generated and treatment needed. Results of the alternatives show that each alternative is applicable to supply the required water to the mine site. However, the storage of the Gediz River water in a v small dam in wet seasons to be used later in dry seasons and the reuse of waste water of Turgutlu after treatment are the alternatives with least impacts on existing water users and related ecosystems.

Considering the current demands of our global world, there is a need for educating students equipped with diverse and complex qualities. In order to educate well-equipped students and sustain quality education, teachers and teacher educators have to be keeping themselves up-to-date and develop themselves professionally. The primary aim of this study is to explore English instructors&rsquo / understanding of professional development through the use of phenomenological research methodology. The data sources were instructors and administrators working at Faculty Academic English Program at Bilkent University. The data collection method was semi-structured, face-to-face interviews. The findings of the study indicated that participants see professional development as a means of individual development, as a means of institutional development and as a source of developing community and environment. The study also revealed that the instructors preferred informal modes of professional development activities to formal ones. Participants of the study overall reflected their agreement on the positive contribution of course design on their professional development, autonomy and self-growth.
