Purpose: The limited uptake of improved agricultural practices in Africa raise questions on the functionality of current agricultural research systems. Our purpose is to explore the capacity for local innovation within the research systems of Ethiopia, Malawi and Mozambique.

Design/methodology/approach: Using Conservation Agriculture (CA) as a case study, we qualitatively explore with 26 locally based agricultural researchers the context of CA research and promotion, including their perceptions on persistent research gaps and issues in closing them.

Findings: Respondents identified that CA was not yet a finished product, with concerns regarding the benefit, feasibility and relevance of CA implementation. They asserted that while further adaptation was required, they were unable to do this due to institutional constraints within their research, extension and policy contexts.

Practical implications: We find that CA continues to be considered a donor-driven intervention in its current form and requires substantial further adaptation to local contexts before researchers will deem it ready for farmer uptake. The five research gaps identified by respondents highlight practical areas where further adaptations must occur.

Theoretical implications: Our findings suggest a lack of participatory research and extension most likely reflects limited financial, human and social capital to implement more participatory approaches. Without addressing these capacities, widespread adoption of complex farming systems change appears unlikely.

Originality/Value: Whilst many studies have identified a need for local innovation to enable CA utilisation, few have qualitatively explored directly with local researchers the capacity of such systems to do so. We address this gap in the literature.  相似文献

Successive governments have pledged to enhance the quality of apprenticeship in Britain so as to achieve ‘parity of esteem’ with academic study. Yet, at the same time, the discourse of the academic-vocational divide has dominated the academic, policy-maker and practitioner debates. This paper draws on two recent studies designed to explore the learner identities of apprentices on different apprenticeship programmes: motor vehicle maintenance (level 2) and engineering (level 3). Through this work, we are able to explore the role of the academic–vocational divide in identity construction and to challenge assumptions about vocational learners. It will be argued, that, far from being ‘naturally practical’, the young people draw on normative discursive categories in their construction of continuous identities. The findings raise important questions about the UK apprenticeship system as currently conceived, while at the same time drawing attention to the possibility for change.  相似文献

This paper explores the issues and concems identified by a small group of teachers implementing technology ideas using the national document,A Statement on Technology for Australian Schools (Curriculum Corporation, 1994a), represented in four key questions they posed as a result of reflection upon their existing ideas and practices, early in the study. These same issues and concerns framed their later experiences as the study progressed. The case study of one of the teachers is used, to illustrate how the teachers implemented technology education working from their own perspectives and tackling issues and concerns that made sense to them. By reviewing the teachers' own questions about technology implementation, it is becoming, clear that what may be important for professional development in technology education is related to the questions that the teachers themselves are asking about their own, beliefs and practices.  相似文献

There is an increasing rhetoric from politicians for universities to become more involved in policy analysis and policy research. In this article, we reflect on our experiences of the analysis we conducted into the legislation to introduce biometric identity cards in the United Kingdom. We highlight how our work had direct consequences for the ongoing policy deliberation around this controversial piece of legislation. In particular, we highlight our role in the debate surrounding the government's figures for identity fraud and the concerns about the likely cost of the scheme to the government and taxpayer. We end the article by discussing some of the practical realities of such a foray into real politik.  相似文献

The paper explores issues surrounding portrayal in educational research and interrogates the notion of a life as a textual product, via an analysis of two short biographical narratives which happen to portray the same person — a British primary school head teacher nearing the end of his career. The discrepancies between these two texts point to the problematic nature of the relationship between person and portrait, and make visible some of the textual devices that writers/researchers use in order to achieve coherence and authenticity in biographical narratives.  相似文献

Coaching efficacy (CE) represents the extent to which coaches believe they have the capacity to affect the learning and performance of their athletes, and the CE model details antecedents, dimensions and outcomes of CE. Based around the CE model, the present paper had two main aims. First, to present a comprehensive and critical review of the research underpinned by the CE model. Studies were categorised by whether they investigated antecedents, outcomes or athletes’ perceptions of their coach. Twenty-one published studies were identified for the review. Overall the review provides support for the main tenets of the CE model, with researchers establishing links between CE and many of the antecedents and outcomes proposed in the model. The second aim was to assimilate findings from the review, limitations in the CE model and relevant conceptual models to present a revised CE model. Whilst retaining the essence of the original model, the revised model also incorporates explicit processes linking coach beliefs and athlete perceptions, antecedents of athlete perceptions and an intrarelationship source of CE. It also incorporates specific categories of coach behaviour and athlete-/team-level outcomes. The paper concludes by identifying limitations in the literature and review, and by proposing key directions for future research.  相似文献

With the advent of the ERASMUS programme a new impetus has been given to the exchange of students between countries within the European Community. Having outlined the aims and objectives of ERASMUS, the authors take as a case-study the development of links between the Universities of Birmingham and Grenoble III (Stendhal University), from the initial inter-university agreemart to the creation of an ERASMUS diploma. The problems posed by diffetences in university systems and practices in Britain and France are identified. Academic issues discussed include the relative merits of contrastive and complementay study programmes, the tailoring of course packages to the needs of specific groups of students, linguistic difficulties, assessment and validation procedures. After a brief consideration of practical arrangements, the article concludes with an evaluation of lessons which are to be learnt and of the extent to which such an initiative might be said to fulfil the ideals of the ERASMUS program.  相似文献
