ABSTRACTThis paper argues that the divergent performance of the rural economies of China and India after 1950 was a product of the different capabilities of the Chinese and Indian governments to mobilize the labor force and financial resources of the rural population. By mobilizing unpaid labor and the financial resources of the villagers through mediation by the collectives (before 1984) and local administrations (from 1984 to the abolition of agricultural taxation and compulsory rural labor mobilization in 2006), the Chinese state developed rural infrastructure and the quality of the labor force at a pace and geographical scope that was far beyond its limited fiscal capacity. Efforts by the Indian state to establish rural organizations with similar mobilization capabilities failed due to the effective opposition of well-entrenched political and economic interests in the countryside. Unable to mobilize the labor and financial resources of the villagers, the Indian government relied primarily on its limited fiscal resources, which produced a much slower development of physical infrastructure and labor force quality. These are the primary reasons why China’s rural economy developed much more rapidly than India’s, which contributed significantly to the divergence of their national economies in the post-1950 era. 相似文献

This article argues that if the introduction of genetically modified crops (GM crops) in developing countries is to be successful, we can and should not evade questions of access and control of technology. It implies probing into the experiences, perceptions and understanding of GM crops by the prime user: the farmer. Exactly in these respects the scholarly literature is remarkably silent. We know little about farmers' experiences and perceptions of GM crops' potential risks and benefits. This is evident when concentrating on a major GM crop – Bt cotton – and studying this in the context of China, its second largest producer in the world. Based on the results of a large survey, we demonstrate that Chinese farmers' awareness (‘having heard of’) and their understanding (‘being able to explain’) of Bt cotton is low. This may lead to ill-informed, distorted risk perceptions and a general inability to relate agricultural production problems to the specific nature of transgenic cotton cultivation. A great majority of the farmers find that the Chinese seed market was liberalised too early, in turn leading to a high incidence of ‘stealth transgenics’ or illegal seeds, the undermining of farmers' trust in private institutions, and a weakened biosafety regime. This finding points to the need for continued state intervention in the seed market, particularly in a developing context. Finally, we have discovered that farmers report a significantly lower reduction in pesticide use by Bt cotton than found in other studies. As suggested by recent research, we suspect that the higher pesticide use is necessary to control secondary pests – i.e. pests other than the cotton bollworm. We present empirical evidence that Chinese farmers perceive a substantive increase in secondary pests after Bt cotton was introduced. 相似文献

Agroecology has played a key role in helping Cuba survive the crisis caused by the collapse of the socialist bloc in Europe and the tightening of the US trade embargo. Cuban peasants have been able to boost food production without scarce and expensive imported agricultural chemicals by first substituting more ecological inputs for the no longer available imports, and then by making a transition to more agroecologically integrated and diverse farming systems. This was possible not so much because appropriate alternatives were made available, but rather because of the Campesino-a-Campesino (CAC) social process methodology that the National Association of Small Farmers (ANAP) used to build a grassroots agroecology movement. This paper was produced in a ‘self-study’ process spearheaded by ANAP and La Via Campesina, the international agrarian movement of which ANAP is a member. In it we document and analyze the history of the Campesino-to-Campesino Agroecology Movement (MACAC), and the significantly increased contribution of peasants to national food production in Cuba that was brought about, at least in part, due to this movement. Our key findings are (i) the spread of agroecology was rapid and successful largely due to the social process methodology and social movement dynamics, (ii) farming practices evolved over time and contributed to significantly increased relative and absolute production by the peasant sector, and (iii) those practices resulted in additional benefits including resilience to climate change. 相似文献

A new political geography has emerged in the Middle East and North Africa (MENA) after the Arab Spring. The transformative impact of the popular upheavals appeared to put an end to long-term authoritarian regimes. Today, the region is far from stable since authoritarian resilience violently pushed back popular demands for good governance and is pushing to restore former state structures. However, the collective consciousness of the popular revolts endures, and a transformative prospect may emerge on the horizon. The chaotic situation is the result of an ongoing struggle between those who seek change and transformation and others in favour of the status quo ante. A critical evaluation of the Arab Spring after five years indicates a continuous process of recalculation and recalibration of policies and strategies. There are alternative routes for an eventual settlement in the MENA region, which are in competition against both regional and transregional quests for a favourable order. 相似文献

The purpose of this article is to explain how public managers can influence the mix of institutional logics in a process of organizational change. To do this, the concept of post-transformational leadership is related to institutional logics. The article is based on a case study of the Danish Crime Prevention Council. The study shows how post-transformative leaders are urged to move from strategies of collaboration to strategies of manipulation, hypocrisy, and the hijacking of institutional logics. 相似文献

There is limited research that has examined experimentally the effects of muscular images on adolescent boys’ body image, with no research specifically examining the effects of music television. The aim of the current study was to examine the effects of viewing muscular and attractive singers in music video clips on early, mid, and late adolescent boys’ body image, mood, and schema activation. Participants were 180 boys in grade 7 (mean age = 12.73 years), grade 9 (mean age = 14.40 years) or grade 11 (mean age = 16.15 years) who completed pre- and post-test measures of mood and body satisfaction after viewing music videos containing male singers of muscular or average appearance. They also completed measures of schema activation and social comparison after viewing the clips. The results showed that the boys who viewed the muscular clips reported poorer upper body satisfaction, lower appearance satisfaction, lower happiness, and more depressive feelings compared to boys who viewed the clips depicting singers of average appearance. There was no evidence of increased appearance schema activation but the boys who viewed the muscular clips did report higher levels of social comparison to the singers. The results suggest that music video clips are a powerful form of media in conveying information about the male ideal body shape and that negative effects are found in boys as young as 12 years. 相似文献

This article discusses the challenges that continue to exist in the struggle for full and equal citizenship in Norway, focusing particularly on the multidimensional citizenship that has been central to the overarching project of women's movements. It reports on comparative research on the social, economic, multicultural, and intimate dimensions of citizenship which offers grounds to regard Norway as an example of good practice and supportive policies in relation to gendered citizenship, and at the same time highlights that fully equal and just citizenship remains to be achieved, particularly for minoritized women. 相似文献

Sharp force trauma is a common homicide method. The weapon is typically a knife, which is easily accessible and does not require special skills. We have analyzed all 471 sharp force homicides in Denmark during 1992–2016 with special focus on aspects that are relevant to forensic pathologists, including the distribution of wounds and organ injuries. Most homicides were committed inside with a kitchen knife. The front left thorax was the most common area to be affected by sharp force trauma. In 18.9% of the victims, there was only one sharp injury, the majority on the thorax. The most common trajectory for stab wounds was directly posterior with no deviation to the sides or up/down followed by directly anterior. The heart (including pericardium) and lungs (including hemo- and pneumothorax) had injuries in more than 75% of the victims. 67% of victims were males. Female victims had more sharp force injuries and defense wounds than male victims. Most females were killed in domestic homicides (73.7%), most commonly in partner killings (56.4%). In contrast, many male victims were killed in a setting of nightlife/intoxication (34.0%) most by a friend/acquaintance delivering a few stab wounds. The results clearly show strong sex differences in both victims and offenders. This could be useful for shaping policies and public opinion, and as a route for understanding the developments in interpersonal violence. In the narrow setting of death investigation, our results will provide an evidence-based approach to understanding the injury patterns in sharp force homicide. 相似文献
