Prior research has shown that victimization incidents are disproportionately concentrated among relatively few victims and that prior victimization is a consistent predictor of future risk. This paper expands existing knowledge on victimization by describing temporal patterns of risk and by developing and testing alternative explanatory models of the link between past and future risk. Analyses based on panel data from the National Youth Survey support both state dependence and heterogeneity interpretations of the correlation in risk over time. In other words, prior victimization predicts future risk in part because it alters something about the individual, and because it indicates an unmeasured propensity for victimization that persists over time. The theoretical implications of these findings, including the feasibility of a victim labeling perspective, are discussed.An earlier version of this paper was presented at the annual meeting of the American Society of Criminology, Phoenix, 1993.An exception to this lack of attention is the vast literature in the area of domestic abuse. 相似文献

The implementation of the Surface Mining Control and Reclamation Act (SMCRA) of 1977 in coal producing states is guided by a partial preemption policy approach t h a t establishes a balance between federal and state decision-making authority. The usefulness of this approach is assessed by analyzing state enforcement actions in relation the institutional capacity of states to shoulder regulatory responsibilities and the propensity of the federal Office of Surface Mining (OSM) t o oversee state enforcement actions and, if necessary, to undertake corrective action. Our results indicated that state administration of SMCRA was canstrained by the lack of effective federal oversight but was largely unaffected by interstate differences in political, economic, or administrative characteristics. 相似文献

A nurse was accused of attempting to murder her anesthesiologist husband on two occasions by administering to him a neuromuscular blocking agent. In both episodes, urine specimens were obtained from the victim shortly after the suspected assaults. The samples were initially tested fluorometrically using Rose Bengal dye as a pairing agent. Both were presumptively positive for pancuronium. Confirmation of these results was achieved by pairing the drug with potassium iodide, extracting the complex, and submitting the extract to thin-layer chromatography (TLC) cleanup, elution at the appropriate retardation factor (Rf), and, finally, gas chromatography/mass spectrometry (GC/MS) analysis in the selected-ion monitoring mode. The two quaternary amines of pancuronium appear to undergo pyrolytic N-demethylation in the injection port to yield an entity amenable to capillary column gas chromatography. The mass spectrum of the compound consists of a base peak of m/z 322, with additional fragments of 292, 323, 338, and 397 m/z, each of which was monitored. The confirmed positive findings were instrumental in adjudicating the case. 相似文献
