FARM-Africa South Africa Northern Cape land reform and advocacy programme 2004-2008: final evaluation

FARM-Africa South Africa has played a crucial and important role in filling the gap that existed after the return of land to communities by government in the Northern Cape. Their support to farmer communities during the post-settlement phase has been critical for making productive use of land. During 2004-2008, FARM-SA has worked in 20 community projects in the Northern Cape, benefiting 745 poor households.

Problems with identifying the '8200-year cold event' in terrestrial records of the Atlantic seaboard: a case study from Dooagh, Achill Island, Ireland.

The Northern Hemisphere cooling event 8200 years ago is believed to represent the last known major freshwater pulse into the North Atlantic as a result of the final collapse of the North American Laurentide ice sheet. This pulse of water is generally believed to have occurred independently of orbital variations and provides an analogue for predicted increases in high-latitude precipitation and ice melt as a result of anthropogenically driven future climate change. The precise timing, duration and magnitude of this event, however, are uncertain, with suggestions that the 100-yr meltwater cooling formed part of a longer-term cold period in the early Holocene. Here we undertook a multiproxy, high-resolution investigation of a peat sequence at Dooagh, Achill Island, on the west coast of Ireland, to determine whether the 8200-year cold event impacted upon the terrestrial vegetation immediately downwind of the proposed changes in the North Atlantic. We find clear evidence for an oscillation in the early Holocene using various measures of pollen, indicating a disruption in the vegetation leading to a grassland-dominated landscape, most probably driven by changes in precipitation rather than temperature. Radiocarbon dating was extremely problematic, however, with bulk peat samples systematically too young for the North Atlantic event, suggesting significant contamination from downward root penetration. The sustained disruption to vegetation over hundreds of years at Dooagh indicates the landscape was impacted by a long-term cooling event in the early Holocene, and not the single century length 8200-year meltwater event proposed in many other records in the North Atlantic region.

Continuous assessment activities - correlation with final exam grades and effect on final grades. A business studies experience

In this paper we analyze the partial grades – of continuous assessment activities including the final exam – and the final grades – computed as a weighted average of partial grades – for nine subjects taught in the third year of Business Administration Degree. On one hand, results show that there is a significant positive correlation between the grades of continuous assessment activities (excluded the final exam) and final exam in seven subjects. On the other hand, overall we find that students’ grades in continuous assessment activities (excluded the final exam) help in the improvement of their final grades (i.e., students’ final grades exceed the grades that they would obtain by only taking into account their final exam grades). The results are consistent when the analysis is carried out over each subject area as well as over the grades of the students who registered for the nine subjects.

Burnout as a predictor of all-cause mortality among industrial employees: A 10-year prospective register-linkage study

Objective: Burnout, a psychological consequence of prolonged work stress, has been shown to coexist with physical and mental disorders. The aim of this study was to investigate whether burnout is related to all-cause mortality among employees. Methods: In 1996, of 15,466 Finnish forest industry employees, 9705 participated in the 'Still Working' study and 8371 were subsequently identified from the National Population Register. Those who had been treated in a hospital for the most common causes of death prior to the assessment of burnout were excluded on the basis of the Hospital Discharge Register, resulting in a final study population of 7396 people. Burnout was measured using the Maslach Burnout Inventory-General Survey. Dates of death from 1996 to 2006 were extracted from the National Mortality Register. Mortality was predicted with Cox hazard regression models, controlling for baseline sociodemographic factors and register-based health status according to entitled medical reimbursement and prescribed medication for mental health problems, cardiac risk factors, and pain problems. Results: During the 10-year 10-month follow-up, a total of 199 employees had died. The risk of mortality per one-unit increase in burnout was 35% higher (95% CI 1.07-1.71) for total score and 26% higher (0.99-1.60) for exhaustion, 29% higher for cynicism (1.03-1.62), and 22% higher for diminished professional efficacy (0.96-1.55) in participants who had been under 45 at baseline. After adjustments, only the associations regarding burnout and exhaustion were statistically significant. Burnout was not related to mortality among the older employees. Conclusion: Burnout, especially work-related exhaustion, may be a risk for overall survival. (C) 2010 Elsevier Inc. All rights reserved.

Building Clouds Drifting Walls:Year One Design Studio: A Critical Appraisal

This is a Booklet about a first year design studio in a school of architecture. It describes and reflects on changes that happened in the course over a three year period starting September 2000. The Studio is made up of students from mainstream architecture, and dual courses with landscape and engineering. The booklet is for those who are thinking of studying architecture. It might also be for those already learning and teaching architecture who want to see how other design studios work.

An accelerated method of developing DBT projects using CDIO partner institutions as parallel processors

The cycle of the academic year impacts on efforts to refine and improve major group design-build-test (DBT) projects since the time to run and evaluate projects is generally a full calendar year. By definition these major projects have a high degree of complexity since they act as the vehicle for the application of a range of technical knowledge and skills. There is also often an extensive list of desired learning outcomes which extends to include professional skills and attributes such as communication and team working. It is contended that student project definition and operation, like any other designed product, requires a number of iterations to achieve optimisation. The problem however is that if this cycle takes four or more years then by the time a project’s operational structure is fine tuned it is quite possible that the project theme is no longer relevant. The majority of the students will also inevitably experience a sub-optimal project experience over the 5 year development period. It would be much better if the ratio were flipped so that in 1 year an optimised project definition could be achieved which had sufficient longevity that it could run in the same efficient manner for 4 further years. An increased number of parallel investigators would also enable more varied and adventurous project concepts to be examined than a single institution could undertake alone in the same time frame.
This work-in-progress paper describes a parallel processing methodology for the accelerated definition of new student DBT project concepts. This methodology has been devised and implemented by a number of CDIO partner institutions in the UK & Ireland region. An agreed project theme was operated in parallel in one academic year with the objective of replacing a multi-year iterative cycle. Additionally the close collaboration and peer learning derived from the interaction between the coordinating academics facilitated the development of faculty teaching skills in line with CDIO standard 10.

How Prepared are UK Medical Graduates for Practice? Final report from a programme of research commissioned by the General Medical Council

This programme of research aimed to understand the extent to which current UK medical graduates are prepared for practice. Commissioned by the General Medical Council, we conducted: (1) A Rapid Review of the literature between 2009 and 2013; (2) narrative interviews with a range of stakeholders; and (3) longitudinal audio-diaries with Foundation Year 1 doctors. The Rapid Review (RR) resulted in data from 81 manuscripts being extracted and mapped against a coding framework (including outcomes from Tomorrow's Doctors (2009) (TD09)). A narrative synthesis of the data was undertaken. Narrative interviews were conducted with 185 participants from 8 stakeholder groups: F1 trainees, newly registered trainee doctors, clinical educators, undergraduate and postgraduate deans and foundation programme directors, other healthcare professionals, employers, policy and government and patient and public representatives. Longitudinal audio-diaries were recorded by 26 F1 trainees over 4 months. The data were analysed thematically and mapped against TD09. Together these data shed light onto how preparedness for practice is conceptualised, measured, how prepared UK medical graduates are for practice, the effectiveness of transition interventions and the currently debated issue of bringing full registration forward to align with medical students’ graduation. Preparedness for practice was conceptualised as both a long- and short-term venture that included personal readiness as well as knowledge, skills and attitudes. It has mainly been researched using self-report measures of generalised incidents that have been shown to be problematic. In terms of transition interventions: assistantships were found to be valuable and efficacious for proactive students as team members, shadowing is effective when undertaken close to employment/setting of F1 post and induction is generally effective but of inconsistent quality. The August transition was highlighted in our interview and audio-diary data where F1s felt unprepared, particularly for the step-change in responsibility, workload, degree of multitasking and understanding where to go for help. Evidence of preparedness for specific tasks, skills and knowledge was contradictory: trainees are well prepared for some practical procedures but not others, reasonably well prepared for history taking and full physical examinations, but mostly unprepared for adopting an holistic understanding of the patient, involving patients in their care, safe and legal prescribing, diagnosing and managing complex clinical conditions and providing immediate care in medical emergencies. Evidence for preparedness for interactional and interpersonal aspects of practice was inconsistent with some studies in the RR suggesting graduates were prepared for team working and communicating with colleagues and patients, but other studies contradicting this. Interview and audio-diary data highlights concerns around F1s preparedness for communicating with angry or upset patients and relatives, breaking bad news, communicating with the wider team (including interprofessionally) and handover communication. There was some evidence in the RR to suggest that graduates were unprepared for dealing with error and safety incidents and lack an understanding of how the clinical environment works. Interview and audio-diary data backs this up, adding that F1s are also unprepared for understanding financial aspects of healthcare. In terms of being personally prepared, RR, interview and audio diary evidence is mixed around graduates’ preparedness for identifying their own limitations, but all data points to graduates’ difficulties in the domain of time management. In terms of personal and situational demographic factors, the RR found that gender did not typically predict perceptions of preparedness, but graduates from more recent cohorts, graduate entry students, graduates from problem based learning courses, UK educated graduates and graduates with an integrated degree reported feeling better prepared. The longitudinal audio-diaries provided insights into the preparedness journey for F1s. There seems to be a general development in the direction of trainees feeling more confident and competent as they gain more experience. However, these developments were not necessarily linear as challenging circumstances (e.g. new specialty, new colleagues, lack of staffing) sometimes made them feel unprepared for situations where they had previously indicated preparedness.

Wishful Thinking: Lessons from the internal and external evaluations of an innovatory education project in Northern Ireland

From March 1999 to August 2000, the authors were involved in simultaneous internal and external evaluations of the social civic and political education (SCaPE) project in Northern Ireland. This project was a major initiative established by the Citizenship Foundation, the Northern Ireland Council for the Curriculum, Examination and Assessment (CCEA), and the School of Education at the University of Ulster at Coleraine. It was a 2-year project in 25 secondary schools established to design, develop, pilot and evaluate a new programme of social, civic and political education for Northern Ireland. It also aimed to serve as a model for future Citizenship curriculum developments throughout Northern Ireland and elsewhere. This paper describes the background to the project, the design and conduct of the two evaluations, and the links between them. It outlines the main conclusions of each evaluation and describes the way SCaPE has since evolved into a mainstream curriculum development project. The final part of the paper analyses the key opportunities, tensions and challenges involved in running such evaluations at a critical time in the history of Northern Ireland – a time when innovation is both necessary and controversial. It argues that, especially in such circumstances, evaluation cannot be conducted from a neutral, objective standpoint, and that it is incumbent on evaluators to recognise the emotional, personal and political commitment they make to the projects in which they are engaged.

Formação de professores de ciências para o uso de tecnologias

Na atualidade, torna-se premente que os alunos exerçam um papel ativo face a problemáticas de cariz científico e tecnológico na sociedade em que se inserem. Neste contexto, tem sido recomendada a promoção da Educação em Ciências, com orientação Ciência-Tecnologia-Sociedade (CTS) para o desenvolvimento da Literacia científica dos alunos, em particular, do Ensino Básico (EB). As Tecnologias da Informação e Comunicação (TIC) têm-se assumido, cada vez mais, como recursos privilegiados para os alunos aprenderem ciências. Portanto, é fundamental que os professores de Ciências do EB considerem os aspetos pedagógico-didáticos relacionados com a integração das TIC no processo de ensino e aprendizagem (E/A) das Ciências. No entanto, vários estudos têm revelado que a maioria dos professores parece não integrar as TIC no processo de E/A, o que se relaciona, entre outros obstáculos, com a falta de formação a este nível. Por outro lado, em Portugal, são escassos os estudos relacionados com a formação de professores de Ciências do EB para o uso de TIC no processo de E/A, com orientação CTS. O presente estudo tem como finalidade a criação de uma proposta de esquema referencial para o desenvolvimento de programas de formação (PF) de professores de Ciências do EB com orientação CTS (inicial, contínua e pós-graduada), com vista ao desenvolvimento de “competências TIC” destes (futuros) profissionais. Para tal, procurou-se responder a duas questões de investigação: Que componentes curriculares privilegiar em PF de professores do EB, que contribuam para o desenvolvimento de competências de integração das tecnologias no processo de E/A, em geral, e das Ciências, em particular?; e Qual o contributo de um PF na promoção de práticas pedagógico-didáticas com orientação CTS de Professores de Ciências do EB? O estudo organizou-se em duas fases. A Fase I designou-se “Formação de Professores do Ensino Básico em Tecnologia Educativa”, decorreu entre janeiro de 2009 e novembro de 2009, e teve um caráter exploratório com vista a descrever estratégias para a promoção do desenvolvimento pessoal, social e profissional, em particular, na dimensão do Conhecimento Pedagógico Tecnológico de Conteúdo (CPTC), de estudantes/professores do EB (inicial, contínua e pós-graduada). O CPTC representa o conhecimento de professores do EB para integrar as TIC no processo de E/A das Ciências, de acordo com a Perspetiva de Ensino por Pesquisa (EPP). A recolha de dados envolveu: a análise documental de vinte e três unidades curriculares (UC) de Tecnologia Educativa (TE) de Cursos de Educação Básica (1.º Ciclo de Bolonha), de dezassete Instituições de Ensino Superior Público Português; e o inquérito por entrevista a quatro Investigadores Portugueses em TE. A análise de conteúdo do corpus recolhido possibilitou a identificação dos componentes curriculares a privilegiar em PF de professores do EB neste âmbito, tais como: i) a “competência digital” de “pesquisa, seleção e organização de informação”; ii) a “competência pedagógica com TIC” de “planificação e/ou implementação de atividades de E/A”; iii) a “competência pedagógica com TIC de nível avançado” de reflexão crítica; iv) o conteúdo curricular centrado na colaboração online; v) a estratégia/atividade de E/A de trabalho de projeto; vi) o cenário de E/A misto (b-learning); vii) as ferramentas da web 2.0 (ex. Blog); e viii) a avaliação formativa de portefólios digitais desenvolvidos pelos estudantes/professores do EB em formação. A Fase II denominou-se “Formação de Professores de Ciências do Ensino Básico com Orientação CTS”, decorreu entre dezembro de 2009 e maio de 2011, e teve um caráter interventivo, com o intuito de conceber, produzir, implementar e avaliar um PF com esta orientação. O PF foi integrado nas UC de “TIC e Educação em Ciências” (TIC_EC) e de “Didática das Ciências Integradas II” (DCI_II) do Mestrado em Didática, área de especialização das Ciências, da Universidade de Aveiro (no 2.º semestre do ano letivo 2009/2010). O Mestrando dirigiu-se a um público profissionalizado, em particular, Educadores de Infância, Professores do 1.º CEB e Professores de Matemática e Ciências Naturais do 2.º CEB. A avaliação do PF foi contínua durante todo o seu processo de desenvolvimento, o que implicou a recolha das perceções dos principais envolvidos (os dois Docentes de DCI_II e de TIC_EC, os nove Mestrandos, um especialista externo em TE e a Investigadora do estudo). Para tal recorreu-se ao inquérito por questionário e por entrevista, à observação participante da Investigadora e à análise dos portefólios digitais desenvolvidos pelos Mestrandos durante o PF. A avaliação final do PF ocorreu no final do mesmo e dez meses após a formação ter terminado (maio de 2011). A análise de conteúdo do corpus recolhido permitiu demonstrar que o PF foi exequível e eficaz no contexto em que se projetou, o que se comprova na evidência de práticas pedagógico-didáticas de utilização das TIC no processo de E/A das Ciências, com orientação CTS, por parte de Mestrandos envolvidos no PF. O esquema referencial resultante do estudo integra a “estratégia de investigação conduzida pelo professor”, pressupõe a sinergia entre as áreas científicas da Didática das Ciências (DC) e da TE, e implica a integração da dimensão do CPTC ao nível da formação de professores de Ciências do EB (inicial, contínua e pós-graduada). Neste âmbito, sugere-se o desenvolvimento de projetos CTS pelos (futuros) profissionais, com recurso às TIC, e tendo em conta a perspetiva de EPP. Considera-se que estudos desta natureza poderão ser um contributo para impulsionar a Educação em Ciências com orientação CTS recorrendo às potencialidades educativas das tecnologias, em particular no EB. Assim, preconiza-se a necessidade de se investir na transferência, expansão e avaliação do referencial a outros contextos de formação de professores de Ciências.

The rise and demise of a book-review magazine interpreting the cultural work of Books in Canada (1971-2008)

This interdisciplinary study examines the contribution that a book-review magazine makes to the cultural identity of its readers. It is the result of reflections on the cultural work of Books in Canada , on whether or not this periodical was a cultural worksite and if that is the case how it performed that cultural work. In addition, it interrogates factors that may have contributed to the magazine's demise. The study affirms that Books in Canada, a cultural enterprise from 1971 to 2008, mirrored and helped to shape book and literary culture in Canada through its circulation, through the personalities of its editors, through its front covers and through its reviewers and their reviews. Furthermore, it proposes that the demise of the enterprise was due to a combination of factors. The study begins with an introduction to book reviewing and special-interest magazines. Chapter I examines the interplay between selected visual and textual contents published in Books in Canada in its founding years. These components reflected and helped to fuel the cultural nationalism that was sweeping Canada subsequent to the 1967 World's Fair in Montreal. There were also persistent rumours and comments about the magazine that caused certain"cracks in the foundation" to appear. Chapter II compares the aims and editorial challenges of Val Clery, founder of Books in Canada , with those of Adrien Thério, founder of Lettres québécoises, and of the editors of the magazines' twentieth-anniversary issues, Paul Stuewe in the case of the former and André Vanasse in the case of the latter. Evidence in the content of the magazine, editorial and otherwise, indicated that the"contracts" that the editors made with their readers over the years were similar, to reflect and shape a cultural identity, but the result of their"projects," that is, the nature of those identities, was distinctly different. Evidently then, personal aims, preferences and political leanings of editors can have a major impact on the content of a book-review magazine and thus on the cultural work that it does. Therefore, in Chapter III, I focus on selected contents published during the tenures of two of Books in Canada 's key editors, Paul Stuewe and Olga Stein, in order to understand ways that their choices constituted a form of cultural work. The second part of this chapter moves from an analysis of the cultural work of editors to an examination of the cultural work of reviewers. Here, through a close-reading of a selection of reviews published in Books in Canada, and in other periodicals, I argue that reviewers do cultural work in the way that they negotiate their presence in a review, and in how they signal that presence through lexical choices and through the degree of intellectual interaction that they invite. Intellectual interaction is at the core of Chapter IV.This chapter consists of close readings of some of the"billboards" of the enterprise, that is, the front covers of Books in Canada , in order to show how these important components do cultural work by requiring readers to make an intellectual leap from image to text. Chapter V suggests that book reviews, the company's"bills of goods," do cultural work in much the same way as the paratexts of a book. One of my own reviews is offered as a case-study along with a number of other reviews of how central components of a book-review magazine do cultural work through the illocutionary force of their sentences. The first part of Chapter VI, the final chapter, measures the legacy of the magazine, in particular, the annual Books in Canada First Novel Award. Created in 1976, this prize is awarded to the author of the novel judged by a Books in Canada prize committee to be the best first novel in English of the year. The second part of Chapter VI sheds light on factors that may have contributed to the closure of the enterprise, including the copyright uproar that accompanied the agreement that Adrian Stein, publisher of Books in Canada and Olga Stein's husband, made in 2001 with the online book merchant, Amazon.com. Furthermore, this penultimate section of the study suggests that one of the most important factors in the magazine's demise was the decision by the Steins to exploit their position as owners, publisher, and editor of a book-review periodical, a government-subsidized one at that, to publish their own lengthy pre-trial defense of Conrad Black. The chapter then zooms back from the particular to the general with a broader consideration of the impact of technology and globalization on the book industry and on the ability of Books in Canada to survive in any form, print or digital.

Estratégias de Comercialização de Potência como Medida de Eficiência Energética

A presente dissertação insere-se no âmbito da unidade curricular “ Dissertação” do 2º ano do mestrado em Engenharia Eletrotécnica – Sistemas Elétricos de Energia. Com o aumento crescente do número de consumidores de energia, é cada vez mais imperioso a adoção de medidas de racionalização e gestão dos consumos da energia elétrica. Existem diferentes tipos de dificuldades no planeamento e implementação de novas centrais produtoras de energia renovável, pelo que também por este motivo é cada vez mais importante adoção de medidas de gestão de consumos, quer ao nível dos clientes alimentados em média tensão como de baixa tensão. Desta forma será mais acessível a criação de padrões de eficiência energética elevados em toda a rede de distribuição de energia elétrica. Também a economia é afetada por uma fraca gestão dos consumos por parte dos clientes. Elevados desperdícios energéticos levam a que mais energia tenha que ser produzida, energia essa que contribui ainda mais para a elevada taxa de dependência energética em Portugal, e para o degradar da economia nacional. Coloca-se assim a necessidade de implementar planos e métodos que promovam a eficiência energética e a gestão racional de consumos de energia elétrica. Apresenta-se nesta dissertação várias propostas, algumas na forma de projetos já em execução, que visam sensibilizar o consumidor para a importância da utilização eficiente de energia e, ao mesmo tempo, disponibilizam as ferramentas tecnológicas adequadas para auxiliar a implementação dos métodos propostos. Embora os planos apresentados, sobejamente conhecidos, tenham imensa importância, a implementação nos vários consumidores de sistemas capazes de efetivamente reduzir consumos tem um papel fundamental. Equipamentos de gestão de consumos, que são apresentados nesta dissertação, permitem ao consumidor aceder diretamente ao seu consumo. Podem aceder não apenas ao consumo global da instalação mas também ao consumo específico por equipamento, permitindo perceber onde se verifica a situação mais desfavorável. Funcionalidades de programação de perfis tipo, com limitações de potência em vários períodos horários, bem como possibilidades de controlo remoto com recurso a aplicações para Smartphones permitem a redução de consumos ao nível da rede de distribuição e, desta forma, contribuir para a redução dos desperdícios e da dependência energética em Portugal. No âmbito do trabalho de dissertação é desenvolvida uma metodologia de comercialização de potência, que é apresentada nesta tese. Esta metodologia propõem que o consumidor, em função dos seus consumos, pague apenas a quantidade de potência que efetivamente necessita num certo período de tempo. Assim, o consumidor deixa de pagar uma tarifa mensal fixa associada á sua potência contratada, e passará a pagar um valor correspondente apenas à potência que efetivamente solicitou em todas as horas durante o mês. Nesta metodologia que é apresentada, o consumidor poderá também fazer uma análise do seu diagrama de cargas e simular uma alteração da sua tarifa, tarifa esta que varia entre tarifa simples, bi-horária semanal, bi-horária diária, tri-horária semanal ou tri-horária diária, de forma a perceber em qual destas pagará um menor valor pela mesma energia. De forma a que o consumidor possa perceber se haverá vantagem de uma alteração para uma potência contratada flexível, ou para uma outra tarifa associada á energia, tem ao seu dispor uma ferramenta, que em função dos seus consumos, permite retirar conclusões sobre o preço final a pagar na fatura, após cada tipo de alteração. Esta ferramenta foi validada com recurso a várias simulações, para diferentes perfis de consumidores. Desta forma, o utilizador fica a perceber que realmente pode poupar com uma potência contratada flexível, ao mesmo tempo que pode identificar-se com um perfil de simulação e, mais facilmente, perceber para que alteração tarifária pode usufruir de uma maior poupança.

Niagara alternative food projects : networks, discourses and nature /

This thesis undertakes an exploration of the nature of alternative food projects in Niagara. A review of various theoretical approaches to the study of food and agriculture, suggests that actor-network theory offers the most useful lens through which to understand these projects. In particular, actor-network theory facilitates non-dualistic theorisations of power and scale and a commitment to the inclusion of non-humans in the 'social' sciences. The research is based on 19 in-depth interviews with actors involved in various urban and rural projects including community supported agriculture, community gardens, chefs using local seasonal food, a winery that grows organically, the good food box, a value-added small business, and organic producers. The analysis consists of four themes. The first analytical section pays special attention to the prominence of agri-tourism in Niagara, and examines the ways in which the projects in the sample interact with agri-tourist networks. In the second section the discussion focuses on the discourses and practices of resistance among Niagara alternative food actors. The participants' interviews suggest there are more discourses of resistance toward agri-tourist than toward dominant food networks. The third section questions commodity chain theorisations of alternative food projects. In particular, this section shows how the inclusion of non-human actors in an analysis confounds conceptualisations of 'short' and 'local' chains. The final analytical section assesses relations of power in Niagara alternative food projects. Three important conclusions arise from this research. First, Niagara alternative food projects cannot be conceptualised as operating at the 'local' scale. Broadening the scope of analysis to include non-human actors, it becomes apparent that these projects actually draw on a variety of extra-local actors. They are at once local and global. Second, the projects in this sample are simultaneously part of alternative, dominant and agri-tourist networks. While Niagara alternative food projects do perform many of the roles characteristic of alternative food systems, they are also involved in practices of development, business, and class distinction. Thus, alternative food networks should not be understood as separate from and in direct opposition to dominant food networks. Despite the second conclusion, this research determines that Niagara alternative food projects have made significant strides in the reworking of power. The projects represented in this thesis do engage in resistant practices and are associated with increased levels ofjustice.

How Learning Styles, Chemistry Attitudes and Experiences, Confidence, and Demographics Correlate with Academic Success in First and Second Year Chemistry Courses

At Brock University, the Faculty of Mathematics and Science currently has one of the highest percentages of students on academic probation, with many students reporting the most difficulty with Introductory Chemistry in first year and Organic Chemistry in second year. To identify strategies to improve students' performance and reduce the number of students on academic probation, a multi-year research project was undertaken involving several chemistry courses. Students were asked to complete three questionnaires, and provide consent to obtain their final Chemistry grade from the Registrar's Office. Research began at the end of the 2007-08 academic year with CHEM IPOO, and in the 2008-09 academic year, students in the larger CHEM IF92 Introductory Chemistry course were invited to participate in this research near the beginning of the academic year. Students who went on to take second year Organic and Analytical Chemistry were asked to complete these questionnaires in each second year course. The three questionnaires included the Kolb Learning Styles Inventory (Kolb, 1984) modified to include specific reference to Chemistry in each question, Dalgety, ColI, and Jones' (2002) Chemistry Attitudes and Experiences Questionnaire (CAEQ), and lastly, a demographic survey. Correlations were found between learning style and academic success; concrete learners were not as successful as abstract learners. Differences were noted between females and males with respect to learning styles, academic success, and confidence. Several differences were also noted between those who are the First in the Family to attend university and those who are not First in the Family to attend university.
