This article examines interstate variation in household food security. Using hierarchical modeling, we identify several kinds of state characteristics that appear linked to household food security: the availability and accessibility of federal nutrition assistance programs, policies affecting economic wellbeing of low income families, and states' economic and social characteristics. These dimensions comprise what we refer to as the state food security infrastructure. We find that a strong food security infrastructure is particularly beneficial to families who are economically vulnerable yet have incomes above the poverty line. Almost all of the observed interstate differences in food security can be explained by crossstate differences in demographic and contextual characteristics. © 2006 by the Association for Public Policy Analysis and Management  相似文献

Spontaneous cerebellar hemorrhages are a rare but often fatal occurrence in children. Although there are several predisposing factors such as blood dyscrasias or astrocytomas, the most common cause of cerebellar hemorrhage in an otherwise healthy child is the rupture of a vascular malformation. We reviewed the files of the Office of Chief Medical Examiner of the City of New York and found four such instances over a period of less than two years. We present these here and outline the approach the forensic pathologist should take in evaluating such deaths.  相似文献

The December 1996 peace settlement in Guatemala agreed a series of institutional reforms in order to recognise the rights of the country's indigenous peoples; some 23 different ethno‐linguistic groups which make up 60% of the overall population. This article explores the relationship between pluri‐culturalism, citizenship, democracy and law in the contemporary politics of Guatemala. While territorially autonomous regions or separate legal jurisdictions are often proposed as a means to ensure indigenous rights, I argue that within a framework of post‐conflict reconstruction, integration with a measure of autonomy for democratically organised communities is the ideal. This is linked to development of an integrative form of citizenship which combines both social membership and identity and rights. Finally, I argue that support for pro‐active efforts to challenge the legacies of authoritarianism, militarisation and inequality will be necessary in order to strengthen democracy, build a culture of citizenship and increase justice.  相似文献

This study examined the relationship between mothers' eating attitudes and weight-loss attempts and their adolescent daughters' body dissatisfaction and weight-loss attempts. Two modes of transmission of mother's values to the daughter (modeling and encouragement) and two forms of weight-loss behavior (moderate and extreme) were examined. Female 10th and llth graders and their mothers completed eating attitudes and behaviors questionnaires. Daughter's moderate weight-loss attempts (e.g., dietary restraint and exercising) and its associated body dissatisfaction were significantly associated with mother's encouraging her daughter to lose weight. In contrast, daughter's more extreme weight-loss behaviors (e.g., fasting, crash dieting, and skipping meals) were predicted by mother's reports of her own body dissatisfaction and mother's use of extreme weight-loss behaviors herself. These effects were not simply an artefact of daughter's body weight. Implications for theory and prevention were noted.  相似文献
