Mounting evidence documents the extraordinary toll on human health resulting from the consumption of unhealthy food products and physical inactivity. In response to America's growing obesity problem, local policymakers have been looking for legal strategies that can be adopted in their communities to encourage healthful behaviors. In order to provide practical tools to policymakers, this article examines four possible venues for local policy change to improve the health of a community: (1) the school environment (2) the built environment (3) community facilities and (4) the point of sale environment. Finally, the article examines the use of taxes or fees as a means of paying for nutrition policy work as well as potentially reducing the consumption of unhealthy products. This article illustrates that local laws and policies can be a valuable tool in changing a community's environment in order to improve nutritional options and increase opportunities for physical activity.  相似文献

Recent years have seen a broadening of the scope of immigration enforcement. As a result, immigrants free of criminal convictions, once considered low priorities for enforcement, are increasingly subject to arrest, detention, and removal. At the same time, federal immigration authorities have sought the cooperation of states and localities in the enforcement of immigration laws. While there has been growing scholarly attention paid to the ways in which legal geographies can account for variation in local immigration policies, the long‐term effects of these policies on immigrants themselves are often overlooked. In this article, we use the case of Colorado, one of the first states to pass a “show‐me‐your‐papers” law in 2006, and data from two qualitative studies to highlight the collateral consequences of enhanced immigration enforcement on immigrants’ economic opportunities, emotional health and well‐being, and academic trajectories. We situate our analysis within the crimmigration literature and discuss the implications of our findings in light of the current political climate.  相似文献

The assessment of fractures is a key issue in forensic anthropology; however, very few studies deal with the features of fractures due to explosion in comparison with other traumatic injuries. This study focuses on fractures resulting from blast trauma and two types of blunt force trauma (manual compression and running over), applied to corpses of pigs; 163 osteons were examined within forty fractures by the transmission light microscopy. Blast lesions showed a higher percentage of fracture lines through the Haversian canal, whereas in other types of trauma, the fractures went across the inner lamellae. Significant differences between samples hit by blast energy and those runover or manually compressed were observed (< 0.05). The frequency of pattern A is significantly higher in exploded bones than in runover and compressed. Microscopic analysis of the fracture line may provide information about the type of trauma, especially for what concerns blast trauma.  相似文献
