ABSTRACTAlthough India’s cotton sector has been penetrated by various input- and capital-intensive methods, penetration by herbicide has been largely stymied. In Telangana State, the main obstacle has been the practice of ‘double-lining’, in which cotton plants are spaced widely to allow weeding by ox-plow. Path dependency theory primarily explains the persistence of sub-optimal practices, but double-lining is an example of an advantageous path for cash-poor farmers. However, it is being actively undermined by parties intent on expanding herbicide markets and opening a niche for next-generation genetically modified cotton. We use the case to explicate the role of treadmills in technology ‘lock-in’. We also examine how an adaptive locked-in path may be broken by external interests, drawing on recent analyses of ‘didactic’ learning by farmers. 相似文献

This contribution reviews recent critiques of the food sovereignty framework. In particular it engages with the debate between Henry Bernstein and Philip McMichael and analyzes their different conceptualizations of agrarian capitalism. It critically identifies tendencies in food sovereignty approaches to assume a food regime crisis, to one-sidedly emphasize accumulation by dispossession and enclosure and thereby to overlook the importance of expanded reproduction, and to espouse a romantic optimism about farmer-driven agroecological knowledge which is devoid of modern science. Alternatives to current modernization trajectories cannot simply return to the peasant past and to the local. Instead, they need to recognize the desires of farmers to be incorporated into larger commodity networks, the importance of industrialization and complex chains for feeding the world population, and the support of state and science, as well as social movements, for realizing a food sovereign alternative. 相似文献

This study examined community-based clinicians’ (N = 294) attitudes, background/experiences, values, and knowledge relating to issues of co-occurring disorders, which occur at a high rate among adolescents involved in the juvenile justice system. Study results reveal that clinicians self-rate their clinical values and attitudes at or above the expected level of competency, but they concede that their skill and knowledge levels are not adequate. Comparison measures reveal that employment setting conditions, geographic region, hours worked per week, and strongly held convictions about the importance of integrated mental health and substance use disorders service delivery distinguish clinicians’ co-occurring disorders knowledge levels. Implications are offered. 相似文献

One of the causes of the increasing number of ecological distribution conflicts around the world is the changing metabolism of the economy in terms of growing flows of energy and materials. There are conflicts on resource extraction, transport and waste disposal. Therefore, there are many local complaints, as shown in the Atlas of Environmental Justice (EJatlas) and other inventories. And not only complaints; there are also many successful examples of stopping projects and developing alternatives, testifying to the existence of a rural and urban global movement for environmental justice. Moreover, since the 1980s and 1990s, this movement has developed a set of concepts and campaign slogans to describe and intervene in such conflicts. They include environmental racism, popular epidemiology, the environmentalism of the poor and the indigenous, biopiracy, tree plantations are not forests, the ecological debt, climate justice, food sovereignty, land grabbing and water justice, among other concepts. These terms were born from socio-environmental activism, but sometimes they have also been taken up by academic political ecologists and ecological economists who, for their part, have contributed other concepts to the global environmental justice movement, such as ‘ecologically unequal exchange’ or the ‘ecological footprint’. 相似文献

Nudging is a policy instrument that can affect citizen behavior, often by providing information. We argue that nudging can also affect citizens’ knowledge, which can become the basis for future choices. In this manner, providing information can make the nudging initiative stick. We test the effect of an information treatment on three types of knowledge in a field experiment. The treatment consists of information on reading strategies designed to nudge parents to read with their children, randomly assigned to 1438 families. We show how nudging by providing information does in fact increase parents’ knowledge, irrespective of socio-economic background. 相似文献

因鉴定体制特点,公安法医除参与尸体有关的现场勘查工作外,还需进行尸体检验工作。在此过程中,可能面对很多风险,受伤和中毒等事件时有发生。然而,国内公安法医对新冠肺炎等传染病流行期间死亡的尸体如何甄别进行尸体检验鉴定,对现场勘查及尸体检验工作的防护只有少量规定,且内容不够详尽。本文对法医在现场勘查中遇到的尸体及尸体检验中实验室建设、职业现状、风险评估及防范措施等进行了论述。最后,建议出台相关的制度规定等具体约束规范措施,以保障公安法医现场勘查及尸体检验工作的顺利进行,以解除基层鉴定机构和鉴定人的后顾之忧。 相似文献

This study assesses whether gender-based differences in political knowledge primarily result from differences in observable
attributes or from differences in returns for otherwise equivalent characteristics. It applies a statistical decomposition
methodology to data obtained from the 1992–2004 American National Election Studies. There is a consistent 10-point gender
gap in measured political knowledge, of which approximately one-third is due to gender-based differences in the characteristics
that predict political knowledge, with the remaining two-thirds due to male–female differences in the returns to these characteristics.
The methodology identifies the relative contribution of the predictors of political knowledge to each portion of the gap,
and then uses this information to elucidate the underlying sources of the political knowledge gender gap and its prognosis.
Education is the characteristic that most clearly enlarges the gap, with men receiving significantly larger returns to political
knowledge from education than women. Group membership reduces the gap as women obtain gains in political knowledge from belonging
to organizations that do not accrue to men. However, these gains are not sufficient to significantly reduce the gap.

知识经济背景下国际产业转移研究新趋势 总被引:4,自引:0,他引:4
新的国际背景下,传统产业转移理论对国际产业转移的新趋势的解释力逐渐失去了效力,迫切需要有新的突破和发展。文章从弗农产品生命周期理论、比较优势理论、雁行模式理论、产业梯度转移理论、国际分工理论、内部化理论、西方中心论、可持续发展理论等方面分析了国际产业转移发展的新问题,并提出了国际产业转移发展的新动向,认为国际产业转移理论正向东道国、知识因素、产业链、产业风险、跨国公司等方面的互动理论方向发展。 相似文献
