Emergency contraception (EC) can prevent pregnancy after sex, but only if taken within 72 hours of intercourse. Over the past 15 years, access to EC has been expanded at both the state and federal level. This paper studies the impact of those policies. We find that expanded access to EC has had no statistically significant effect on birth or abortion rates. Expansions of access, however, have changed the venue in which the drug is obtained, shifting its provision from hospital emergency departments to pharmacies. We find evidence that this shift may have led to a decrease in reports of sexual assault. 相似文献

In this study, 13C4-secobarbital was used as an exemplar compound to illustrate the mechanism based on which the effectiveness of a proposed internal standard (IS) could be evaluated. A deuterated analog, 2H5-secobarbital, was also studied in parallel for comparison purposes. Well-established solid-phase extraction and methylation procedures were used prior to the GC/MS measurement step. The contribution of the intensity of an ion designated for the analyte (secobarbital) by the proposed IS, and similarly, the contribution of the intensity of an ion designated for the IS by the analyte--a phenomenon termed "cross-contribution"-were evaluated based on a "direct measurement" procedure in which equimolar amounts of the analyte and the IS were used to generate intensity data. These intensity data were then used as the basis for the calculation of "cross-contribution" (in percentages) of ions designated for the analyte and the IS. Cross-contribution data were compared with the linearity data resulting from two series of standards containing 25 to 9600 ng/mL secobarbital using two sets of quantitation ion pairs--m/z 196/200 and 195/199 with 13C4-secobarbital as the IS and m/z 196/201 and 195/200 with 2HS-secobarbital as the IS. 13C4-secobarbital was found to be much less problematic and thus can serve as a very effective IS. Cross-contribution data alone cannot fully explain the observed differences resulting from the use of these two ISs; further systematic study is needed to provide better understanding of the underlying interference mechanism. 相似文献

Despite the veritable influence of the peer context on the elaboration of adolescent aggression, few studies of relational aggression have directly identified and measured peer groups, limiting our ability to draw formal conclusions about the level and nature of peer influence. The current study used a developmental framework to examine peer group influence on individual levels of physical and relational aggression over a year with 6th and 7th grade students (n = 346, 51 % female). A multilevel network approach was used in which peer groups were identified via social network analysis, and peer group influence was evaluated with hierarchical linear modeling (HLM). HLM analyses indicated that peer group aggression (physical and relational) at time 1 was predictive of individual aggression levels at time 2 after controlling for other peer group characteristics as well as other individual risk and protective factors. Although both forms of aggression were embedded in peer networks, findings suggest that physical aggression is relatively less endemic to peer networks, and is more likely to occur in smaller, predominantly male networks. The current study highlights the importance of understanding the influence of peer group membership on adolescent aggression and points to important implications for prevention. 相似文献

This article examines Aquinas’s thinking about law and nature to show that for Aquinas natural law is not about deriving or finding normative rules (standards) in the order of the cosmos or requirements of practical rationality. Rather, I argue that for Aquinas, natural law is a distinctive way of theorizing relationality and embodiment in the “sublunary realm”: one that aims at “friendship” across species lines (STI-II99.2-3). The word Aquinas uses to describe this ecological practice is synderesis. For Aquinas, synderesis is both the human-creaturely capacity to grasp the analogical structuring of reality and the “disposition” that allows us to work on transforming this reality into belonging-together through our participation in natural law (STI79; DV15-17). Synderesis is thus of central importance to Aquinas’s account of natural law, yet it is largely overlooked by modern natural law theorists. The article concludes by exploring how Aquinas’s natural law thinking might contribute to an environmental politics of friendship. 相似文献

This article engages with the liberalist conception of extraterritorial citizenship in examining the pioneering attempt of the Malaysian diaspora to make a rights-based claim for extraterritorial voting. Using the case study of MyOverseasVote (MOV), a transnational advocacy group, this paper demonstrates how the Malaysian diaspora staked their constitutional claim as absent citizens and challenged the state’s definition of absent voters. The bottom-up reform is framed within the context of equalization of rights due to the salient ethnic element embedded in extraterritorial Malaysian citizenship. This liberalization of the external voting legislation has de-ethnicized but not equalized voting rights outside the country between publicly and privately employed citizens overseas. During the 13th General Election (GE13), Malaysia introduced a limited diaspora franchise conditioned upon territoriality and connectivity, affirming the continued relevance of territorial sovereignty. 相似文献

In a recent paper published in the Economic Journal, Professor William D. Nordhaus of Yale University reviewed World Dynamics by Jay W. Forrester. In his criticism, Nordhaus signals three serious problems and several additional questionable assumptions of sufficient importance to undermine the usefulness of Forrester's book. However, a careful examination of his analysis shows that each point made by Nordhaus rests on a misunderstanding of World Dynamics, a misuse of empirical data, or an inability to analyze properly the dynamic behavior of the model by static equilibrium methods.The three serious problems raised by Nordhaus concern the assumptions that connect industrialization to net birth rates in World Dynamics, the representation of technology and production within the world model, and the impact of prices on global resource use. The analysis presented here refutes the Nordhaus arguments and shows that World Dynamics is consistent with his references to real-world data on population, production, and capital accumulation.This paper is a response to William D. Nordhaus, World Dynamics: Measurement Without Data, published in the Economic Journal, Royal Economic Society, December 1973. An earlier, unpublished, version of the Nordhaus paper, bearing the same title, was widely circulated hand-tohand within the United States, Canada, and Europe. A response to the original Nordhaus paper (System Dynamics Group Memorandum D-1736-4) was written in February 1973 and is available from Jay W. Forrester, Alfred P. Sloan School of Management, Massachusetts Institute of Technology, Cambridge, Mass. 02139. The present paper, a revised version of the earlier response, deals with several new or modified arguments contained in the Economic Journal article by Nordhaus. 相似文献

Abstract: This paper examines the realignment of government from a street‐level vantage point. Gleaning inspiration from studies of governmentality and institutional ethnography, the study argues that street‐level processes were intertwined with the consolidation of neoliberal forms of rule. This connection was evident in the growing centrality of voluntary organizations in social administration, which went hand‐in‐hand with a normalization of more extreme forms of poverty. In making this case, the paper draws on research conducted in Fredericton and Saint John, New Brunswick. Sommaire: Le présent article examine le réalignement du gouvernement sous l'angle du point de vue du grand public. S'inspirant d‘études sur la gouvernementalité et l'ethnographie institutionnelle, l'article soutient que les processus grand public ont été entrelacés avec la consolidation des formes néolibérales de règlement. Cette connexion fut évidente dans la centralité croissante des organismes bénévoles au sein de l'administration sociale, qui alla de concert avec une normalisation de formes de pauvreté plus extrêmes. Pour défendre ce point de vue, l'article se fonde sur des travaux de recherche menés à Fredericton et Saint John au Nouveau‐Brunswick. 相似文献

This study aimed to create a measure of risk for gang affiliation, for use in the UK. A pilot stage invited gang affiliated and non-gang affiliated participants between the ages of 16–25 years to retrospectively self-report on 58 items of risk exposure at the age of 11 years. Based on performance of these items, a 26-item measure was developed and administered to a main study sample (n = 185) of gang affiliated and non-gang affiliated participants. Categorical Principal Component Analysis was applied to data, yielding a single-factor solution (historic lack of safety and current perception of threat). A 15-item gang affiliation risk measure (GARM) was subsequently created. The GARM demonstrated good internal consistency, construct validity and discriminative ability. Items from the GARM were then transformed to read prospectively, resulting in a test measure for predictive purposes (T-GARM). The T-GARM requires further validation regarding its predictive utility and generalisability. However, this study has resulted in the first measure of gang affiliation, with promising results. 相似文献
