This article presents an innovative study of the effect of individual states and private institutes in pushing forward stem cell research despite a federal ban on creating new stem cell lines. The author analyzes the impact of state legislation, proposing that states are reacting to federal policy by serving as laboratories for what is traditionally federally funded biomedical research.  相似文献

In R (on the application of Friends of the Earth Ltd and others) v Heathrow Airport Ltd the UK Supreme Court allowed an appeal against the Court of Appeal's decision that there had been a series of legal errors in the designation of the Airport National Policy Statement. This case note analyses the case from an ‘internal’ doctrinal perspective and argues that the Supreme Court could have engaged more explicitly with the legal issues that arise from climate change legislation for administrative law adjudication. For courts to adjudicate well in such circumstances they need to be prepared to develop administrative law doctrine, particularly in light of the issues of integrating climate change into public decision-making and of scientific/policy uncertainty which lie in the background of climate change legislation.  相似文献

Abstract

Plans and policies to combat or mitigate gentrification typically pursue affordable housing production and preservation as the primary mechanism to avoid displacement. However, it is unclear whether affordable housing financing mechanisms function as designed in weak market cities. As such, we question whether the housing-only approach is a complete one and whether increased transportation investments in redeveloping neighborhoods in shrinking cities can be leveraged to improve the lives of the poor. Our results suggest that funding for subsidized housing does not produce units affordable to the poor in declining cities, limiting the efficacy of a housing-only approach. Furthermore, we find that transportation costs make up a larger proportion of household budgets among families living in declining neighborhoods. These results suggest that transportation improvements—particularly those aimed at bicycling and pedestrian accessibility—may be the most efficient approach to mitigating displacement and improving quality of life for low-income households in shrinking cities.  相似文献

Wie sich der Prozess der EU-Erweiterung zu Geschlechterfragen verhält, ist Gegenstand dieses Aufsatzes. EU-Fallstudien über drei Beitrittsländer bilden die empirische Grundlage für die Analyse: Tschechien, Polen und Slowenien. Der Artikel besteht aus drei Teilen. Der erste Teil befasst sich mit dem gesetzlichen Rahmen der EU und insbesondere mit dem Geschlechterkontext in der EU-Politik und den Standards, die den zukünftigen Mitgliedern auferlegt werden. Der zweite Teil umreißt die sozialen und wirtschaftlichen Bedingungen, unter denen Frauen in diesen Ländern leben, arbeiten und sich um ihre Partner, Familien und Freunde kümmern. Der dritte Teil schließlich untersucht die Genderdiskurse im Dialog der EU mit den Anwärterländern und befasst sich besonders mit den unterschiedlichen Reaktionen der Regierungen und der NGOs.  相似文献

Researchers have found an inverse relationship between immigrant status and violence perpetration. Most studies have examined Mexican immigrants, and few have assessed immigration factors other than nativity. Additionally, the majority have focused on the most serious forms of violence despite the fact that moderate violence is more common. Using data from the 2008 Boston Youth Survey, we generated prevalence estimates of peer violence perpetration across immigration related factors, examined whether risk factors for peer violence differed by these variables, and explored the contribution of risk factors to peer violence perpetration. Recent immigrants had a significantly lower prevalence of peer violence compared to each other generations/time in U.S. group. Known risk factors for violence perpetration varied by generation/time in U.S.: compared to other groups, recent immigrants were less likely to have used substances, and were more likely earn A's and B's in school. Recent immigrants had a significantly lower risk of violence perpetration relative to U.S.-born (RR = 0.35, 95% CI: 0.19, 0.62). Adjusting for known risk factors did not attenuate differences in risk. While immigrant youth had a lower risk of peer violence, the protective effect was diminished among immigrants who had resided in the U.S. for >4 years. This pattern demonstrates that negative assimilation occurs within the first generation, not just across generations. Results suggest that perpetration of violence worsens with increased time in the U.S. Research is needed to identify factors that contribute to the acquisition of behaviors such as violence among recently arrived immigrant youth.  相似文献

Abstract: The frontal sinuses are known to be unique to each individual; however, no one has tested the independence of the frontal sinus traits to see if probability analysis through trait combination is a viable method of identifying an individual using the frontal sinuses. This research examines the feasibility of probability trait combination, based on criteria recommended in the literature, and examines two other methods of identification using the frontal sinuses: discrete trait combinations and superimposition pattern matching. This research finds that most sinus traits are dependent upon one another and thus cannot be used in probability combinations. When looking at traits that are independent, this research finds that metric methods are too fraught with potential errors to be useful. Discrete trait combinations do not have a high enough discriminating power to be useful. Only superimposition pattern matching is an effective method of identifying an individual using the frontal sinuses.  相似文献

Although there is a knowledge base regarding theoretical and empirical research on attitudes toward the police, this line of research has not fully examined the sources of such attitudes, and in particular the extent to which attitudes toward the police are influenced by ethnic identity. The present study examined the role of ethnic identity in African American adolescent offenders' perceptions of general police discrimination, direct police contact, procedural justice, and police legitimacy. Analyses showed that youth with a stronger sense of ethnic identity perceived more police discrimination but reported more positive beliefs about police legitimacy. The findings underscore the importance of considering processes that may make legal socialization experiences more salient for adolescents, and demonstrate the complex role that ethnic identity plays in relation to discrimination.  相似文献

This research note provides an overview and an update on the social and political backgrounds of all elected Canadian legislators at the federal and provincial/territorial levels of government in 1996. For provincial/territorial legislators data are presented by electoral jurisdiction, and for all legislators by level of government and political party. Relatively few differences in social characteristics were found between the two levels although there were some variations by province, territory and party. Business, education and law are the three most prevalent occupations, although the latter has declined among legislators over time. There is little movement of members from the provincial to the federal level. The most common political experience of both groups lies in municipal governance. Over time women have increased their share of seats at both levels. Even in a polity such as Canada with high rates of legislative turnover at both federal and provincial/territorial levels and with new parties emerging, most changes in social and political experience backgrounds proceed incrementally.  相似文献
