As the field of strategy reaches its 25th anniversary, we examine how far the field has progressed during that time. Both management and strategy research have been characterized as being in an early stage of development. We draw on Kuhn's ( 1996 ) paradigm development model, which posits a connection between a field's stage of maturity and research processes and outcomes, to assess the maturity of the strategy field. We conduct two studies. The first is a cross‐discipline comparison of productivity norms for university faculty. The second study examines longitudinal research outcomes for a sample of 945 strategy faculty. Our results indicate that strategy has the attributes of both an early stage and mature field: while overall research norms are low relative to other fields, they are driven far more by merit‐based than non‐merit factors.

Providing nutritious and environmentally sustainable food to all people at all times is one of the greatest challenges currently facing society. This problem is particularly acute in Africa where an estimated one in four people still lack adequate food to sustain an active and healthy life. In this study, we consider the potential impact of future population growth and climate change on food security in Africa, looking ahead to 2050. A modelling framework termed FEEDME (Food Estimation and Export for Diet and Malnutrition Evaluation) was used which was characterized to model the impacts of future climate changes (utilizing the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios projections) and projected population growth on food availability and subsequent undernourishment prevalence in 44 African countries. Our results indicate that projected rapid population growth will be the leading cause of food insecurity and widespread undernourishment across Africa. Very little to no difference in undernourishment projections were found when we examined future scenarios with and without the effects of climate change, suggesting population growth is the dominant driver of change. Various adaptation options are discussed, such as closing the yield gap via sustainable intensification and increasing imports through trade and aid agreements. These strategies are likely to be critical in preventing catastrophic future food insecurity.  相似文献

Understanding the social processes that support innovations in new biotechnologies presents an interesting challenge. Evidence from the Australian bioindustry reveals how the development and integration of new biotechnologies is a dynamic social process. Our findings highlight how new technology acceptance and integration rested on the micro‐politics of sense‐making and relational networking.  相似文献

This paper reviews what has been learned from experiences of African agriculture and hence what policy lessons may be. Views of African agriculture over the last 130 years have changed from optimism to pessimism and at least halfway back again as the performance of the sector has fluctuated. Fortunately it seems the deep pessimism about agricultural prospects expressed in the 1980s and 1990s has receded. The performance of African agriculture since 1990 suggests that neither those who doubt that any significant advances are taking place, nor those who see advances in some remarkable but perhaps isolated cases of rapid transformation of farming and agricultural supply chains, have sufficient evidence – either from national data or small‐scale studies – to support their positions. Hence policy has to rely largely on general principles and historic lessons, rather than more clearly proven propositions. Policy debates over African agricultural development may sharply divide on some topics, but there is little debate over the importance of basic conditions for agricultural development of an enabling investment climate and the provision of rural public goods. Beyond these basics, the challenge is to remedy the failings of markets that deny most smallholders access to inputs, financial services and insurance. Here opinion divides between whether to return to public provision, as with fertiliser subsidies, or whether private and collective institutional innovations will be sufficient. Recent initiatives to test and scale up the latter look promising, but most have yet to be evaluated. If agricultural development is first and foremost about establishing the basic conditions for growth, then most countries in Africa may be better placed than they have been in the past. Given the many examples that show African smallholders investing and innovating when they have the chance, then there are reasons to hope that the modest growth of production and productivity seen in the last two decades may accelerate in the future – thereby allowing African countries to make the transition from agrarian to urban economies.  相似文献

This article provides new evidence on the effect of changes in employment protection on worker absence. We use novel multi‐organization data to examine changes in worker absence as workers move from temporary to permanent employment contracts. We demonstrate a robust positive effect of employment protection on sickness absence. It has also been suggested that the impact of employment protection on absence and effort is due to a fear of dismissal. We also provide evidence that suggests that temporary workers' absence is influenced by incentives to attain jobs with protection that is unrelated to threat of dismissal. This has not been considered in earlier research. This channel of employment protection effects has important policy implications.  相似文献

This study tests five potential drivers underlying the acceptance of SMS advertising. After developing a scale to measure behavioral responses to SMS advertising, the relationships between the acceptance of SMS advertising, intention to receive SMS advertising and behavioral responses to SMS advertising are tested. A convenience sampling method was employed. Survey questionnaires were distributed across Western Australia. The return yielded 203 usable questionnaires from the respondents. Several factors emerge as significant drivers of acceptance of SMS advertising including utility of SMS advertisements, context of SMS advertisements and attitudes to advertising in general. Contrary to expectation, control over SMS advertisements did not emerge as a significant driver for acceptance of SMS advertising. Trust in advertisers and laws did not emerge as a significant driver of the acceptance of SMS advertising among Australian respondents. Advertisers who pursue consumer acceptance should strive to build utility and context considerations into their SMS campaigns. Future research opportunities include testing the drivers of SMS advertising to further investigate the impact of control and trust on acceptance of SMS advertising in other countries where the SMS advertising has not been explored yet.  相似文献

Through a case study contrasting the impacts of formalised and informal teleworking practices on office‐based workers, multidimensional dilemmas between flexibility, control and equity are uncovered. Formal schemes, although problematic and rare, possess some advantages in resolving the three dimensions. A model is proposed to test findings further.  相似文献

Turnovsky observes that “the rational expectations hypothesis has had a profound impact on macroeconomic theory and policy during the past decade.” Tracing briefly the evolution of the ideas involved, he concludes that “… a consensus view is emerging that in fact under quite plausible conditions the policy neutrality proposition does not hold; therefore, there is still scope for policy rules to play an important role in stabilizing output.”

The mathematics used in the article is expository rather than analytical, requiring of the reader only somewhat more than the usual amount of persistence, faith in the author's interpretation of the literature, and a willingness to accept the integrity of economic models as representative of the real world. This is “required” reading for those teaching macroeconomics.  相似文献
