Indigenous vegetables play an important role in Kenyan food security, but production is limited by poor seed quality. Traditionally, seeds have been traded through informal networks, but a new formal seed sector is emerging. This study assessed the relative potential for formal or informal seed systems to meet the need for high-quality indigenous vegetable seed. By evaluating determinants of farmers’ seed purchasing behaviour, we conclude that informal seed systems have greater potential to meet this need and should be strengthened. This study suggests that policy-makers should use context-specific data to guide decisions on seed policy.  相似文献

Voela and Tamboukou use Slavoj ?i?ek’s notion of the symptom as a lens through which to look at representations of female figures in Greek literary texts of the early twentieth century by Gregorios Xenopoulos. In mapping the construction of the figure of the modern woman in the matrix of discourses, fantasies and power relations of fin-de-siècle Greece, they draw on psychoanalytic insights, interrupted by Foucauldian interventions. Following Judith Butler’s move of making trouble they attempt to open up a dialogic space between psychoanalytic and Foucauldian approaches to the female subject, contextualized in a specific social, historical and cultural milieu. It is in this context that they discuss, first, how feminine and masculine subjectivities are represented in man’s speech; second, how unintended excesses and interruptions occur in the problematic representation of women; and, third, how madness and ultimately death come to play a significant role in the power relations between the sexes.  相似文献

In this paper, I look into personal and political entanglements in Rosa Luxemburg’s letters and essays revolving around questions and problems of the revolution. The analysis is informed by Hannah Arendt’s theorisation of revolutions in modernity, as well as her reading of narratives within the political. What is intriguing about the Luxemburg/Arendt encounter is the fact that although both theorists consciously refused to connect themselves with feminist ideas and movements of their times and geographies, their writings have inspired a rich body of feminist theorisations of the political. What I argue is that Luxemburg’s ideas and lived experiences of the revolution largely inspired Arendt’s theorisation of the revolution as a political phenomenon in the pursuit of freedom, and are opening up new vistas in our understanding of gendered dynamics in historical and contemporary revolutionary events.  相似文献

The fundamental distinction between Ricardo and Marx is once more examined, chiefly with reference to the current spread, among some leftwing economists, of a neo-Ricardian school. So a crucial point seems to be the particular meaning, which is quite a-Ricardian, of the first section of the Capital. Anyhow, this section is often misunderstood, because of its difficulty, and its philosophical form.  相似文献

Changes in the nature, scale, and speed of natural resource extraction, especially in the last two decades, have resulted in many new resource extraction areas emerging across the world. By zooming in on Indonesia, this article shows that the underlying causes and consequences of current trends are more complex than portrayed by the rancher-squatter model of frontiers that is still frequently used to explain these developments. We argue that a broadened frontier notion is necessary to address the multifaceted nature of the processes underway in contemporary Indonesian extraction areas, as well as beyond. We propose a perspective that pays explicit attention to four new developments that can be described by using the hybridization of space, time, actors, and rules, and are characterized by the fact that these processes create new perimeters in all four mentioned areas. In so doing, we challenge, broaden, and renew the meaning of frontiers.  相似文献

This paper investigates informal mechanisms of knowledge transfer (KT) from a local university to entrepreneurial teams comprising students and recent graduates. While the extant literature on university-industry KT largely focuses on formal mechanisms aimed at stimulating entrepreneurial initiatives in high-tech (HT) sectors, it overlooks the effect of university-industry KT on nascent entrepreneurship in low-medium tech (LMT) sectors. To fill this gap in the literature, we carry out a mixed-method analysis that exploits a dataset of 154 new business ideas (and 535 team members) presented at a business plan competition in Rimini from 2010 to 2017. Our findings highlight a robust relationship between educational field and the R&D intensity of entrepreneurial projects: students take advantage of the knowledge acquired at university to develop entrepreneurial projects with higher technological content than those planned by non-graduates. Furthermore, the empirical evidence shows that the local university nurtures the formation of ties among students and recent graduates enrolled in the same courses and fosters their efforts to launch new ventures. Finally, the qualitative analysis identifies relevant and non-traditional mechanisms of KT that are being exploited by nascent entrepreneurs to develop their business ideas in the LMT and HT sectors.
