The interaction of welfare and child support regulations has created a situation in which child support policy's incentives that discourage unwed fatherhood tend to be stronger than its incentives that encourage unwed motherhood. This suggests that more stringent child support enforcement creates incentives that reduce the likelihood of nonmarital childbearing, particularly among women with a significant chance of needing public assistance in the event of a nonmarital birth and their male partners. We investigate this hypothesis with a sample of women from the Panel Study of Income Dynamics, to which we add information on state child support enforcement. We examine childbearing behavior between the ages of 15 and 44 before marriage and during periods of non‐marriage following divorce or widowhood. The estimates indicate that women living in states with more effective child support enforcement are less likely to bear children when unmarried, especially if they are young, never‐married, or black. The findings suggest that improved child support enforcement may be a potent intervention for reducing nonmarital childbearing. © 2006 by the Association for Public Policy Analysis and Management.  相似文献

Participants (N = 200) were presented with a criminal homicide trial involving a battered woman who had killed her abuser. Within the trial, both the response history (passive, active) and presence of expert testimony pertaining to battered woman syndrome (present, absent) were systematically varied. As well, half of the participants in each of these conditions were provided with a nullification instruction informing them that they were free to disregard the law and acquit should a strict application of the law result in an unjust verdict. Results indicated that, compared to the passive response condition, the mock jurors were no less receptive to the expert testimony in the active response condition. The impact of the testimony on participants' verdicts, however, was moderated by the nullification instruction. That is, although the presence of the testimony did result in greater verdict leniency, this only occurred when the mock jurors had been released from a strict application of the law. The implications of these findings are discussed.  相似文献

A sensitive analytical method was developed for quantitative analysis of delta(9)-tetrahydrocannabinol (delta(9)-THC), 11-nor-delta(9)-tetrahydrocannabinol-carboxylic acid (delta(9)-THC-COOH), cannabinol (CBN) and cannabidiol (CBD) in human hair. The identification of delta(9)-THC-COOH in hair would document Cannabis use more effectively than the detection of parent drug (delta(9)-THC) which might have come from environmental exposure. Ketamine was added to hair samples as internal standard for CBN and CBD. Ketoprofen was added to hair samples as internal standard for the other compounds. Samples were hydrolyzed with beta-glucuronidase/arylsulfatase for 2h at 40 degrees C. After cooling, samples were extracted with a liquid-liquid extraction procedure (with chloroform/isopropyl alcohol, after alkalinization, and n-hexane/ethyl acetate, after acidification), which was developed in our laboratory. The extracts were analysed before and after derivatization with pentafluoropropionic anhydride (PFPA) and pentafluoropropanol (PFPOH) using a Hewlett Packard gas chromatographer/mass spectrometer detector, in electron impact mode (GC/MS-EI). Derivatized delta(9)-THC-COOH was also analysed using a Hewlett Packard gas chromatographer/mass spectrometer detector, in negative ion chemical ionization mode (GC/MS-NCI) using methane as the reagent gas. Responses were linear ranging from 0.10 to 5.00 ng/mg hair for delta(9)-THC and CBN, 0.10-10.00 ng/mg hair for CBD, 0.01-5.00 ng/mg for delta(9)-THC-COOH (r(2)>0.99). The intra-assay precisions ranged from <0.01 to 12.40%. Extraction recoveries ranged from 80.9 to 104.0% for delta(9)-THC, 85.9-100.0% for delta(9)-THC-COOH, 76.7-95.8% for CBN and 71.0-94.0% for CBD. The analytical method was applied to 87 human hair samples, obtained from individuals who testified in court of having committed drug related crimes. Quantification of delta(9)-THC-COOH using GC/MS-NCI was found to be more convenient than GC/MS-EI. The latter may give rise to false negatives due to the detection limit.  相似文献

The majority of Asian states have not signed onto the major international refugee law instruments which promote refugee recognition and protection. Yet, second to Africa, the Asian region has had the highest number of refugees since the Second World War. Three explanations are usually offered to explain this puzzle —“good neighbourliness”, “economic costs” and “social disruption”. In this article I argue that each is flawed in important ways and then develop an alternative by explaining how limited Asian involvement in the drafting of international refugee law has led Asian states to reject Eurocentric refugee recognition practices.  相似文献

Can a Member State choose to leave the European Union (EU)? Are there provisions in the Treaties that establish a right to withdraw? What would the political and economic implications be? In this article, these questions are addressed. In a first step, the Treaties of the EU and the provisions of international law are consulted in order to clarify if a legal right to withdraw exists. The conclusion is that there is no guaranteed legal right to withdraw in the current situation, but the entering into force of the Treaty establishing a Constitution for Europe would create such a right. However, a formal right to withdraw does not necessarily mean that leaving the EU is a real option, and therefore the political and economic sides of the issue are also examined. From the literature on secession and Europeanization, a number of issues that could arise in a case of withdrawal are identified – namely ‘fear of fragmentation’, ‘lost investment’, ‘costs’ and ‘the effects of Europeanization’. The extent to which these issues were of importance is examined in the only existing case of withdrawal: Greenland. Subsequently, an assessment is made of the extent to which these issues could form obstacles for a Member State that wishes to withdraw in the current situation. The main conclusion is that large economic costs and the constitutional changes that follow from EU membership could rule out withdrawal as a realistic option.  相似文献
