Despite significant improvements over recent decades, rates of undernutrition remain high in South Asia, with adverse impacts on morbidity and mortality. Overweight/obesity, among children and adults, is now an additional and major public health concern. While agriculture has the potential to improve nutrition through several pathways, this potential is currently not being realised in the region. The Leveraging Agriculture for Nutrition in South Asia (LANSA) research consortium (2012–2018) set out to improve understanding about how agriculture and related food policies and programs in South Asia (specifically in India, Bangladesh, Pakistan and Afghanistan) can be better conceptualised and implemented in order to enhance impacts on nutrition outcomes, especially those of young children and adolescent girls. This paper provides a snapshot of the agriculture-nutrition nexus in the region, outlines the pathways through which agriculture can influence nutrition outcomes, elaborates on the objectives of the LANSA research consortium within this context, and highlights the core findings of the six papers that form the body of this Special Issue. The paper ends with five key lessons that have emerged from this research, during this decade.  相似文献

Emotions have a significant effect on the processes of designing and creative thinking. In an educational context, some emotions may even be detrimental to creativity. To further explore the link between creativity and emotion, a series of interviews were conducted with design and technology (D&T) teachers in Singapore, Hong Kong and Beijing concerning their experiences of working with students on design projects. The intent was to investigate how these teachers understood and managed their students’ emotions while teaching creative design skills. Some teachers indicated that they understood their students’ emotions through observing their behaviour, connecting with them by synchronising emotions or by evaluating student performance. The teachers also reported using various other methods to handle their students’ emotions. This study highlights the importance of equipping D&T teachers with skills for awareness and regulation of emotions so that they can better enable students to cultivate creativity in the design process.  相似文献

In this article, we critically review the three most common approaches of assessing chronic food insecurity and undernutrition: (i) the FAO indicator of undernourishment, (ii) household food consumption surveys, and (iii) childhood anthropometrics. There is a striking and worrying degree of inconsistency when one compares available estimates, which is due to methodological and empirical problems associated with all three approaches. Hence, the true extent of food insecurity and undernutrition is unknown. We discuss strengths and weaknesses of each approach and make concrete suggestions for improvement, which also requires additional research. A key component will be the planning and implementation of more comprehensive, standardized, and timely household surveys that cover food consumption and anthropometry, in addition to other socioeconomic and health variables. Such combined survey data will allow much better assessment of the problems’ magnitude, as well as of trends, driving forces, and appropriate policy responses.  相似文献

There has been very little research into children’s technological practice in early childhood settings. This article describes four typical examples of the technological activity that occurs on a daily basis in New Zealand early childhood settings. It is suggested that children come to compulsory schooling with well-developed technological knowledge and competence in instigating and carrying out technological tasks that is not recognized and taken advantage of by the majority of primary early years programme developers and teachers. A number of ways by which early years school technology programmes could benefit by recognizing the extent of children’s emergent technological literacy and amending programme delivery and teaching strategies are detailed.  相似文献

This study examines how directors make decisions that involve shareholders and other stakeholders. Using vignettes derived from seminal court cases, we construct an index of directors' shareholderism as a general orientation on this issue. In a survey of the entire population of directors and CEOs in public corporations in one country, we find that directors' personal values and roles play an important part in their decisions. Directors and CEOs are more pro‐shareholder the more they endorse entrepreneurial values—specifically, higher achievement, power, and self‐direction values and lower universalism values. While employee representative directors exhibit a lower baseline level of shareholder orientation, they nonetheless often side with shareholders. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

Engineering design practice has been recognized as an effective approach to engage students in STEM learning. However, we noticed that students who possessed strong STEM knowledge did not necessarily perform well on their design projects. Thus, this study sought to explore factors that shaped students’ design objectives and means. A design-based research was adopted using a single group teaching experiment, in which students’ performance in relation to conceptual knowledge, engineering design practice, and their STEM attitudes were assessed in different design complexity groups. Based on the findings of this study, we concluded that students’ interest and metacognitive skills might be the key factors affecting their motivation during the engineering design process. Their abilities in predictive analysis and testing/revising were core elements affecting their design thinking. Our work provides preliminary evidence on how students form and present different design purposes and objectives in an engineering design project.  相似文献

The professionalism of teachers is based on three levels of expertise: mastering academic knowledge, mastering the teaching of this knowledge and mastering the role played by teachers in schools. For each of these levels, each student during the teacher training courses has his own understanding. This understanding influences their perception of the job of teacher and thus their attitude towards their training. Efficiency of this training could be evaluated through the evolution of this understanding. The experimental part of this study will involve looking at this evolution with students from the ENSET in Libreville at the beginning of the training course, the end of the first cycle and the end of the second cycle. Data collected shows that training does not really produce the desired results for a university vocational teacher training course for technology education.  相似文献

Understanding the complex relationship between water, agriculture and poverty (WAP) is essential for informed policy-making in light of increasing demand for scarce water resources and greater climatic variability. Yet, our understanding of the WAP nexus remains surprisingly undeveloped and dispersed across multiple disciplines due to conceptual (biophysical and economic) and measurement issues. We argue that water for agriculture will need to be better managed for it to contribute to reductions in poverty and vulnerabilities. Moreover, this management will need to consider not just quantities of water, but the quality of the water and the multiple agricultural and non-agricultural uses. For this reason, expanding research in WAP needs to involve interdisciplinary efforts. We identify three key knowledge gaps in WAP that are particularly pressing in light of greater climatic variability. These are climate change adaptation, over-abstraction of groundwater, and water quality.  相似文献

The use of auctions as an instrument of public policy has been hailed as evidence of the utility and validity of game theory. In this paper, we focus on extreme cases – centrally, spectrum auctions in the UK and Germany in 2000 – to argue that the canonical game theoretic interpretations of firm behaviour in some (highly “successful”) auction outcomes are inadequate, that the economics of governance critique of franchise bidding can be extended to provide a better interpretation, and that under specified conditions, notably high uncertainty, policy-makers should design franchise auctions to avoid overbidding, rather than attend to the more conventional challenge of underbidding.  相似文献

Engaging in multiple strategic alliances, a firm forms an alliance portfolio. While a larger alliance portfolio signals investors a firm's ability to exploit new opportunities and improve financial performance, having multiple alliances may also undermine financial performance due to a firm's limited ability to effectively manage these alliances. Announcing an alliance termination, a firm signals an intention to increase the effectiveness of a larger alliance portfolio. This article examines the extent to which alliance termination announcements create value for firms with multiple alliances. Building on the resource-based view of the firm and organizational learning literature, the paper hypothesizes a U-shaped relationship between alliance portfolio size and a firm's cumulative abnormal stock return following an alliance termination announcement. This effect is moderated by the amount of a firm's alternative resources and partner-specific experience that affect its ability to effectively manage multiple alliances. The results show that alliance termination announcements create firm value when an alliance portfolio is large.  相似文献

Over the last decade or so, access to broadband services has become increasingly important. While many in the UK already benefit from the provision of broadband, some, especially those located in more rural and remote areas, do not – they may not be able to access the Internet and when they do, their connection and consumer experience may be poor. After trying to resolve this through a stream of different initiatives, the UK government announced a broadband universal service obligation (USO) of 10 Mbps in late 2015. Ofcom, the telecommunications regulator, launched a consultation in April 2016 and sought the views of interested parties. The consultation attracted considerable interest, but after the submissions from orchestrated campaigns are discounted just over 100 responses remain. But who contributed and what did they say? To explore these two questions, this paper adopts a qualitative approach, using NVIVO, to analyse the responses to the consultation. We show that contributions were highly diverse, reflecting both the complexity of the issue as well as its politicised nature. A lack of agreement among the responses is revealed and divergent views on key issues like the appropriateness of 10 Mbps, whether this should change, how it should be funded or what technologies should be used exist. In this paper, we provide a critical discussion of and derive implications for the broadband USO. We tentatively conclude that those in rural and remote areas that the USO intends to help are caught between two countervailing forces – speed and cost deployment – that interact to ensure that whatever resolution to provide broadband access, some will likely be unhappy.  相似文献

This article contributes to the literature on board effectiveness by being perhaps the first to systematically examine how the nature of outside directors' prior experience, and resulting expertise, will influence the performance of a focal firm's strategic initiatives. Our theoretical model is grounded in the psychological literature on expertise and its role in group decision making effectiveness. We focus on outside director expertise in acquisition decision making, and its implications for the performance of the acquisitions of a focal firm. Our conceptual framework indicates that directors will develop expertise in making particular kinds of acquisition decisions (e.g., related or unrelated acquisitions or acquisitions in specific industries or product markets) through their past experiences at other firms with decisions about those specific types of acquisitions, and we predict that this experience and expertise will have positive effects on the performance of a focal firm's acquisitions. We extend our theoretical model to consider the conditions under which relevant director experience will prove most beneficial. Our model predicts that outside director acquisition expertise will deliver the greatest benefits when the focal firm's board is independent from management. We find empirical support for all of our hypotheses. In considering how and when director experience and resulting expertise may influence the performance of corporate acquisitions, our theory and results help to highlight a potential second main focus for research on the long‐standing question of what factors render boards of directors effective.

Developing countries’ incentives to protect intellectual property rights (IPR) are studied in a model of vertical innovation. Enforcing IPR boosts export opportunities to advanced economies but slows down technological transfers and incentives to invest in R&D. Asymmetric protection of IPR, strict in the North and lax in the South, leads in many cases to a higher world level of innovation than universal enforcement. IPR enforcement is U-shaped in the relative size of the export market compared to the domestic one: rich countries and small/poor countries enforce IPR, the former to protect their innovations, the latter to access foreign markets, while large emerging countries free-ride on rich countries’ technology to serve their internal demand.  相似文献

This paper reports on a professional development that was designed and implemented in an attempt to broaden teachers’ knowledge of the nature of technology and also enhance their technological pedagogical practices. The professional development was organised in four phases with each phase providing themes for reflection and teacher learning in subsequent phases. On-going support, reflection and feedback underpinned the professional development processes to enhance teachers’ prospects of putting aside old traditions and culture to implement new practices in their classrooms. The teachers collaboratively explored new concepts through readings of selected scholarly papers, making presentations of their views generated from the readings and engaging with peers in discussing learning, curriculum issues and concepts related to the nature of technology and technology education. A qualitative analysis of the teachers’ journey through the phases of the professional development showed the teachers’ enhanced knowledge of technology and technology education. However, their classroom practices showed technological pedagogical techniques that reflected their traditional strategies for teaching technical subjects. It is argued that although the teachers’ conceptualisation of learning in technology was still fragile at this point, attempts to shift teachers’ beliefs and practices require deep theoretical grounding and transferring that into technological practices. A professional development built on existing ideas and context helps expand the teachers’ views about the nature of technology and technology education.  相似文献

How do a firm’s internal capabilities and external partnerships contribute to its product and process innovativeness? How do their impacts differ? Based on the theoretical framework of exploitation and exploration, we develop an integrative model linking the impact of both internal capabilities and external partnerships on product and process innovativeness. Survey responses from Taiwanese biotechnology firms indicate that research and development (R&;D), marketing, and manufacturing capabilities have different effects on product and process innovativeness. Of the four types of external partnerships, only partnerships with universities and research institutes seem to add value, whereas partnerships with suppliers, customers, and competitors do not contribute to innovativeness. Moreover, marketing capability and customer partnerships have a positive interaction effect on product innovativeness, while manufacturing capability and supplier partnerships have a positive interaction effect on process innovativeness.  相似文献

The main objective of this study is to provide an overview of the current status quo of negotiation research in marketing. In this context, we first conduct a quantitative analysis of existing literature on buyer–seller negotiations. Specifically, we undertake a screening of 10 high-ranking marketing journals so as to identify the body of negotiation-related articles within marketing. In a next step, the identified articles are subjected to both content and co-citation analyses. To this end, we modify the interaction model of the IMP Group in order to comprehensibly structure the existing findings. In a last step, these findings are presented to various negotiation experts to verify their practical relevance. From this multi-step procedure, we derive sound implications for research and practice.  相似文献

New insights of empirical studies in contract research do not always conform to those that might be expected as a result of these theoretical studies. Much of the research into the nature and form of contracts has been of a theoretical nature and it is often referred as ‘relational contract’ or ‘incomplete contract’ theory. In comparison, a limited number of empirical studies have been undertaken. This paper will set out the findings of these two major streams of theoretical analysis of contracts and then contrast them with recent empirical research into ‘framework contracts’.  相似文献
