Rural water planners assume the positive impacts of community water projects are spread evenly across the population. We test this assumption by looking at the distribution of benefits within communities that received handpumps in rural Mozambique. Using survey and qualitative data we analyse the characteristics of those groups who benefited from the handpumps and also explore household decision-making processes. Handpump use was determined by distance, availability of other sources, perceptions of water quality, political affiliation, and wealth. We argue that the handpumps reinforced existing social divisions related to income and political affiliation and created new geographic divisions within communities. 相似文献

Although property rights have been linked to a variety of positive social outcomes at the macro‐level, less research focuses on how property rights affect the benefits that actors receive at the micro‐level. This article examines property rights to a common‐pool resource (CPR) that are asymmetrically allocated among users, and presents a theoretical argument that property rights affect the allocation of resource benefits in two important ways. First, users with extensive property rights receive more benefits than users with limited property rights. Second, users with the power to influence how community rules are enforced—for example, landholders and ethnic majorities—more effectively define and defend their property and thus receive disproportionate CPR benefits compared to users with similar levels of property rights, but with less power. Using household‐level survey data in Bolivia, Kenya, Mexico, and Uganda, collected after a period of property rights decentralization, the empirical analysis finds support for these propositions. We conclude that power critically moderates the effects of property rights on the commons. 相似文献

In recent decades, highly-publicized school rampage attacks with multiple victims have caused widespread fear throughout the United States. Pulling from in-depth interviews with school officials (administrators, counselors, security and police officers, and teachers), this article discusses officials’ perceptions of fear and risk regarding rampage shootings and how this relates to their justification for and acquiescence to the expansion of punitive discipline and increased security. Data collected in this study provide additional understanding of the causes of enhanced discipline and security from the perspective of those tasked with administering school safety in the wake of Columbine. Utilizing insight from moral panic theory, the findings suggest that, when the genuinely high potential cost of school massacres fused with an exaggerated perception of their likelihood and randomness, school rampage attacks came to be viewed as a risk that could not be tolerated and must be avoided at nearly any cost. 相似文献

Despite substantial increases in the prevalence of adolescent overweight and obesity documented in recent decades, few studies
have prospectively tracked their development during the entire adolescent period. The aims of this study were to characterize
developmental trends in prevalence, incidence, and remission of overweight and obesity using annual data collected from ages
12 to 19 for 496 adolescent females. Ethnic differences between African American (n = 37), Latina (n = 96), and European American (n = 348) adolescents were also compared. The prevalence of overweight decreased slightly across adolescence and remission rates
exceeded incidence (onset). Obesity was more chronic, with increasing incidence accompanied by decreasing remission rates.
Middle through late adolescence was the period of greatest risk for the transition from overweight to obesity. African American
and Latina females had higher overweight and obesity prevalence than European American females throughout adolescence. Differences
in prevalence were driven by higher onset rates for African American and Latina females, whereas remission rates were comparable
across ethnic groups. Results suggest that adolescence is not a high-risk period for onset of obesity for European American
adolescent females, but is for African American and Latina adolescent females. 相似文献

This article addresses the concern that democratization may contribute to the reproduction of neo-patrimonialism, rather than to counteract it. The article reports the result of a survey among members of parliament in Ghana regarding their election campaigns. Total spending, sources of funds, and their usage are analysed in the context of the consolidation of liberal democracy. The survey results are supplemented with data collected in 34 interviews with MPs. The data show that MPs are involved in patron-client relationships to a significant degree to reproduce their political power. Furthermore, the prevalence of patronage politics among MPs in Ghana has increased throughout the period of democratic rule. This persistent pattern of patronage politics threatens the very heart of democratic consolidation. Vertical accountability and legitimacy is threatened by alternative pacts of loyalty, expectations of corruption, and tendencies to delegative mandates. Horizontal accountability risks pervasion by 'big man' interventions, and by insufficient allocation of time to monitoring the government and legislative activities. 相似文献

Whether international human rights treaties constrain the behavior of governments is a hotly contested issue that has drawn much scholarly attention. The possibility to derogate from some, but not all, of the rights enshrined in the International Covenant on Civil and Political Rights (ICCPR) during declared and officially notified states of emergency provides a hitherto unexplored test case. If governments were increasingly violating non-derogable rights during derogation periods then this provides evidence that the ICCPR has no sufficient constraining effect on state parties. I analyze whether specific individual human rights as well as two aggregate rights measures are systematically more violated during derogation periods in a global sample over the period 1981 to 2008. I find that regime type matters: autocracies step up violation of both non-derogable and derogable rights, anocracies increasingly violate some derogable and some non-derogable rights, whereas democracies see no statistically significant change in their human rights behavior during derogation periods. This result suggests that the main general international human rights treaty fails to achieve its objective of shielding certain rights from derogation where, as in autocracies and anocracies, a constraining effect would be needed most. 相似文献
