ABSTRACT

This article examines the role of India’s states in shaping the implementation and framing of social policy within India’s federal system. Since the 2000s, the central government has overseen a substantial expansion of social welfare policies partly through a new push toward rights-based social provision. Yet, it is India’s states that are both responsible for an increasing proportion of total public expenditure on social welfare provision as well as determining the nature and effectiveness of that provision across space. Drawing on a comparative research program across pairs of Indian states, three critical factors explaining how state-level political environments shape social policy are identified: the role of policy legacies in shaping policy frames; the role of social coalitions underpinning political party competition; and the role of political leaders in strengthening state capacity to achieve program goals.  相似文献

This article seeks to explain why electoral support for the Venezuelan opposition has increased substantially, using Venezuelan public opinion survey data from LAPOP and an opt‐in sample collected through the online vote advice application Brújula Presidencial Venezuela. It analyzes why Venezuelans who had either voted for Chávez or abstained in 2006 defected and started to support the opposition in subsequent elections. It proposes several reasons: negative voter evaluations of the economy, concern for public safety, and dissatisfaction with Venezuelan democracy. While the finding that negative policy evaluations boost support for the opposition aligns with theoretical expectations, this study finds a strong relationship between having different evaluations of the quality of democracy and supporting Chávez, which shows that the advocacy of two competing visions of democracy by the incumbent and the opposition also affects voting patterns in Venezuela.  相似文献

The recent conflict in the Sahel area is another case where the nexus of terrorism and organized crime causes challenges to the international community. Comparing the situation with that of the Andean region brings forth the challenges faced when dealing with this type of conflict: the states’ weak presence in the remote regions, the insurgents’ ability to offer income and “security” to the people, immediate threat to international investments, unresolved political/regional issues, the marriage of convenience of insurgents/terrorists and organized crime, internal divisions of the insurgent groups and also ideologies surviving or suffering after the elimination of their leaders.  相似文献

This review article discusses three books on post-communist agrarian reforms. At the heart of the discussion are questions over the efficacy of market reform and rural responses to reform policies. The article argues that the conception of reform that stemmed from the Washington Consensus was often too narrow and did not always lead to expected results, and indeed, sometimes led to unwanted, unintended results. Nonetheless, the three books are highly suggestive of rural adaptation in most post-communist nations. The nature and degree of adaptation to a new economic environment across several post-communist nations represent a critical mass of rural responses. Instead of seeing rural responses as resistant to change, or victims of change, a more nuanced view of reform appreciates the transformation in social and economic relations engendered by market reform.  相似文献

ABSTRACT

This paper examines how intersectional inequalities can facilitate the extraction of surplus value from agriculture. Through an ethnographic case study of the Burkina Faso cotton sector, I describe a ‘chain of exploitation’ wherein actors pass economic pressures on to less-powerful actors. People resist their own exploitation, yet justify exploiting others through discourses about intersectional inequalities – overlapping axes of social difference including class, gender, rural/urban status, and education level. I thus argue that intersectional social inequalities – exacerbated by economic pressures – can: (1) justify and thus facilitate the transfer of exploitation, and (2) fragment resistance efforts.  相似文献

Abstract

This article employs an innovative methodology to study causal mechanisms in the oil–conflict link by combining a systematic approach with taking into account country details. Engaging in a deductive test of causal mechanisms in a controlled comparison of four major oil exporters, results show that no oil-related causal mechanism can fully explain the differences in violence. A more inductive analysis complemented by process tracing suggests a more comprehensive mechanism: oil contributes to the formation of opposition through grievances. Levels of violence, however, vary largely according to non-oil conditions – particularly the cohesiveness of opposition and the reaction of government to challengers.  相似文献

Previous research has shown a consistent positive association between non-suicidal self-injury and depressive symptoms. However, the direction of the effects has not been examined. To understand whether non-suicidal self-injury predicts depressive symptoms or vice versa, we examined the relations between non-suicidal self-injury and depressive symptoms across three waves of self-report data collected 1 year apart from 506 Swedish adolescents (47 % girls; M age = 13.21; SD = .57) who were attending 7th grade at the onset of the study. The results suggest that depressive symptoms predict increases in non-suicidal self-injury 1 year later between the first and second waves of the study. Between the second and third waves of the study depressive symptoms and non-suicidal self-injury were significantly correlated indicating co-occurrence with no direction of effect rather than depressive symptoms predicting non-suicidal self-injury or vice versa. Group comparisons revealed no differences for boys and girls. The findings help clarify the relationships between non-suicidal self-injury and depressive symptoms during middle adolescence.  相似文献

The disintegration of the Soviet Union had profound economic and social effects on many of the newly independent transition economies. Nowhere was this more so than in the fisheries sector – with one of the biggest production shortfalls occurring in Kyrgyzstan, following the collapse of lake capture and pond-culture production. In 2005, aggregate landings were just 48 tonnes – barely 3 per cent of the catch level recorded in 1989. This article has two objectives. First it analyses the extent to which the dissolution of the Soviet Union can explain the collapse of the fisheries sector in Kyrgyzstan. Second, in the light of these findings, it considers what practical steps, if any, might be taken to revitalize the sector.  相似文献

An improved method for detecting diatom in blood is reported. Blood of cadavers was obtained by cardiac puncture at inquest or from the left atrium directly at autopsy. The blood was hemolyzed by sodium dodecyl sulfate (SDS) and filtered through membrane filter (47 mm in diameter and 5 microns in pore size). When the blood was putrefied, two or three pieces of membranes filters were needed because of choking membrane pore. The membrane filters were digested with fuming nitric acid and diluted with distilled water. The diluted solution was filtered through membrane filter (25 mm in diameter) again. After drying the membrane filter was immersed in oil. Diatoms on the membrane filter were clearly observed microscopically.  相似文献

Studies are reported on microbial conversion of various unsaturated fatty acids to 10-hydroxy and/or 10-oxo fatty acids by Micrococcus luteus. Four fatty acids possessing cis-9-unsaturation produced 10-hydroxy and 10-oxo fatty acid products, but three enoic acids possessing trans-9-unsaturation or double bond(s) in other than the 9-carbon position were inactive as substrates. 10-Hydroxy palmitic and stearic acids were converted to the corresponding 10-oxo fatty acids, but the 10-oxo compounds were inactive as substrates. This indicates that the metabolic sequence of cis-9-enoic fatty acid by the microbial enzyme(s) is first converted to 10-hydroxy fatty acid and then to its 10-oxo compound.  相似文献
