Abstract

The number of studies on children in war has steadily increased in the fields of international relations, international law and moral philosophy in recent years. Most of this research has evolved around the legal and moral status of children in war. The status of girl soldiers is particularly intriguing, as it conflates common assumptions about both women and children as innocent victims of war. In this paper we look at narratives of children’s victimhood in the context of war by concentrating on girls who participated, in various forms, in the two Liberian civil wars from 1989 to 1997 and 2000 to 2003. Drawing on interviews conducted with women war veterans, we make the case that the study of child soldiers in general—and girl soldiers in particular—would benefit from a more contextually sensitive and empirically informed study of girls’ experiences, specifically regarding the possibilities and limitations of their capacity to be agents of war. We demonstrate how the agential capacities of children are case sensitive and argue that scholarship must better take into account the complex contextuality of childhood and agency in the study of children in war.  相似文献

This paper studies changes in voting preferences over election campaigns. Building on the literature on spatial models and valence issues, we study whether (1) ideological distance to political parties, (2) assessments of party competence to handle different policy issues, and (3) voter-updated candidate evaluations are factors that explain shifts in voter choices in the weeks preceding the election. To test our hypotheses, we use data from three survey panels conducted for the 2008, 2011 and 2015 Spanish general elections. Our findings show that valence factors are more influential than ideological indifference to account for campaign conversion.  相似文献

Voluntary policy compliance is an important yet rarely studied topic in public administration. To address the paucity of research, this article proposes and empirically tests a conceptual framework that ties policy transparency and policy understanding to voluntary policy compliance intentions. The reasoning is that the extent to which citizens understand a policy contributes to their intentions to comply with that policy. Further, the authors argue that policy transparency indirectly influences voluntary policy compliance intentions through a positive effect on citizens’ levels of policy understanding. To enhance the validity of the findings, the authors assess these relationships across two policy domains. The findings reflect an indirect positive effect of transparency on voluntary compliance occurring through policy understanding. However, this emerged only for one policy domain. These results suggest that the effects of policy transparency on policy understanding and voluntary policy compliance intentions may depend on the policy domain.  相似文献

To examine the infant health impact of prenatal exposure to power plant emissions, we draw scientific evidence on the impacted region downwind of a large polluter, a coal‐fired power plant located on the border of two states and proven to be the sole contributor to the violation of air quality standards of the impacted region. Our results show that among all live singleton births that occurred during 1990 through 2006, those born to mothers living as far as 20 to 30 miles away downwind from the power plant (which is also an affluent region) during pregnancy are at greater risks of low birth weight (LBW) and very low birth weight (VLBW): the likelihoods of LBW and VLBW could increase approximately by 6.50 and 17.12 percent, respectively. In light of the continual efforts of The U.S. Environmental Protection Agency in reducing cross‐state air pollution caused by transboundary power plant emissions, our study is aimed at broadening the scope of cross‐border pollution impact analysis by taking into account adverse infant health effects of upwind polluters, which can impose disproportionate burdens of health risks on downwind states due to air pollutants transported by wind.  相似文献

Southern countries are undergoing a severe economic crisis that has renewed debates about the available strategies to economise their public resources. Political leaders have launched a wide range of different strategies aimed at reducing spending. According to generally accepted political discourse, drastic actions should be taken to guarantee economic and financial sustainability in times of austerity. We explore the main measures adopted by Spanish municipalities in order to examine their impact in budgetary terms. First of all, we identify the most frequently implemented mechanisms including organisational structure, public services and operational economic restructuration. After their quantification, we monitor the presence and impact of each set of policies to analyse the relationship between concrete measures and effective economic impact. The effective reduction of budgets is being implemented but data show that local governments are resilient to non-compulsory changes. The ‘government at a distance’ policy pursued by the central state administration has effectively reduced budgets but has not affected the institutional core of Spanish local governments.  相似文献

Experiences with perceived discrimination (e.g., perceptions of being treated unfairly due to race or ethnicity) are expected to impact negatively youths’ prosocial development. However, resilience often occurs in light of such experiences through cultural factors. The current longitudinal study examined the influence of perceived discrimination on the emergence of Mexican American adolescents’ later prosocial tendencies, and examined the mediating role of Mexican American values (e.g., familism, respect, and religiosity). Participants included 749 adolescents (49 % female) interviewed at 5th, 7th, and 10th grade. Results of the current study suggested that, although perceived discrimination was associated negatively with some types of prosocial tendencies (e.g., compliant, emotional, and dire) and related positively to public prosocial helping, the associations were mediated by youths’ Mexican American values. Directions for future research are presented and practical implications for promoting adolescents’ resilience are discussed.  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
