Interstate extradition law would appear radically altered bythe 1987 U.S. Supreme Court decision in Puerto Rico v. Branstad,overturning a precedent established in Kentucky v. Dennison126 years earlier that extradition could not be legally compelledby the federal government. Dennison, however, is more complexthan is commonly believed, and the demise of one of Dennison'sconclusions does not signal a major overhaul of the SupremeCourt's treatment of extradition. Rather, the Court's decisionshave adhered closely to the original intent of the Constitution'sextradition clause. The part of Dennison overturned was thereforenoteworthy as an exception to the general thrust of the Court'streatment of extradition. How then did Dennison's bar of legallycompelled extradition survive so long when the theory of federalismsupporting the decision had been repudiated long before it wasreversed? This article explores this question and directs attentionto the consequences of Branstad for extradition. Despite theapparent clarity of Branstad, a survey of state extraditionofficers reveals lingering confusion over extradition law.  相似文献

Deconvolution of forensic DNA mixtures into their individual component DNA (geno)types is of great investigative value, though often complex and difficult. Two-person mixtures comprising a major and minor contributor are often easily interpreted although, when the DNA ratio of the two individuals is approximately equal (~1:1), deconvolution and interpretation becomes much more difficult. To address this issue, a physical separation of individual-, two- or three- cell subsamples prior to autosomal STR analysis was performed using a simplified micromanipulation technique paired with a decreased reaction volume and increased cycle number PCR. Using this method, single and multiple buccal epithelial cells were collected from a 1:1 two-person mixture (i.e. from individual 'A' and 'B') and directly amplified, omitting standard DNA extraction and purification steps. Single cell subsamples resulted in partial single-source profiles for both contributors while, in accordance with expectations of a quasi-binomial sampling schema, two- and three-cell subsamples resulted in single source informative partial profiles of individual A and individual B as well as complete consensus profiles, and equally mixed 1:1 (2-cell subsamples) and 2:1 (3-cell subsamples) admixed profiles of individual A and B. This proof-of-concept approach shows promise in permitting the DNA deconvolution of mixed samples where the individual contributors are present in similar amounts that would otherwise be difficult to interpret, resulting in an increase in evidentiary value. The subsampling approach can be readily investigated for DNA casework applications without additional investment in costly, new equipment, requiring only a stereo microscope and a tungsten needle.  相似文献

Most research has conceptualized red tape as being a pathological subset of organizational formalization. This article argues that focusing on a single dimension of organizational structure as a red tape driver is unrealistically narrow. Specifically, the article advances hypotheses as to how organizational centralization and hierarchy affect perceived red tape, in addition to formalization. This reasoning is tested using survey data from employees of three local government organizations in the southeastern United States. All three hypotheses are supported: higher levels of organizational formalization, centralization, and hierarchy are associated with more red tape. Open‐ended comments also indicate that red tape is not solely perceived as related to formalization. The findings imply that red tape is a multifaceted perception of organizational structure rather than perceived pathological formalization.  相似文献

This article synthesizes housing subsidy voucher research to explain why, when in theory vouchers enable users to move out of poor neighborhoods, in practice they often do not. This qualitative meta-analysis presents an examination of the assumptions of the program and their relationship to empirical findings.

Two themes emerged from this synthesis: market barriers and product problems. Data from a variety of studies and contexts portray recipients struggling to use vouchers in the private rental market due to market barriers, including lack of public transportation and the presence of discrimination. Product problems constrained freedom of choice about where to move and when to make a housing transition. These constraints manifest as compromised housing quality and low voucher utilization. This synthetic view cannot account for all outcomes or exceptional cases, but results suggest where participant experiences are generalizable and attributable to features of the housing market and structure of the program itself.  相似文献

Objectives

A key question in the general deterrence literature has been the extent to which the police reduce crime. Definitive answers to this statement, however, are difficult to come by because while more police may reduce crime, higher crime rates may also increase police levels, by triggering the hiring of more police. One way to help overcome this problem is through the use of instrumental variables (IV). Levitt, for example, has employed instrumental variables regression procedures, using mayoral and gubernatorial election cycles and firefighter hiring as instruments for police strength, to address the potential endogeneity of police levels in structural equations of crime due to simultaneity bias.

Methods

We assess the validity and reliability of the instruments used by Levitt for police hiring using recently-developed specification tests for instruments. We apply these tests to both Levitt’s original panel dataset of 59 US cities covering the period 1970–1992 and an extended version of the panel with data through 2008.

Results

Results indicate that election cycles and firefighter hiring are “weak instruments”—weak predictors of police growth that, if used as instruments in an IV estimation, are prone to result in an unreliable estimate of the impact of police levels on crime.

Conclusions

Levitt’s preferred instruments for police levels—mayoral and gubernatorial election cycles and firefighter hiring—are weak instruments by current econometric standards and thus cannot be used to address the potential endogeneity of police in crime equations.

Forensic science is a fundamental transitional justice issue as it is imperative for providing physical evidence of crimes committed and a framework for interpreting evidence and prosecuting violations to International Humanitarian Law (IHL). The evaluation of evidence presented in IHL trials and the outcomes various rulings by such courts have in regard to the accuracy or validity of methods applied in future investigations is necessary to ensure scientific quality. Accounting for biological and statistical variation in the methods applied across populations and the ways in which such evidence is used in varying judicial systems is important because of the increasing amount of international forensic casework being done globally. Population variation or the perceived effect of such variation on the accuracy and reliability of methods is important as it may alter trial outcomes, and debates about the scientific basis for human variation are now making their way into international courtrooms. Anthropological data on population size (i.e., the minimum number of individuals in a grave), demographic structure (i.e., the age and sex distribution of victims), individual methods applied for identification, and general methods of excavation and trauma analysis have provided key evidence in cases of IHL. More generally, the question of population variation and the applicability of demographic methods for estimating individual and population variables is important for American and International casework in the face of regional population variation, immigrant populations, ethnic diversity, and secular changes. The reliability of various skeletal aging methods has been questioned in trials prosecuted by the International Criminal Tribunal for the Former Yugoslavia (ICTY) in The Prosecutor of the Tribunal against Radislav Krstic (Case No. IT-98-33, Trial Judgment) and again in the currently ongoing trial of The Prosecutor of the Tribunal against Zdravko Tolimir, Radivolje Miletic, Milan Gvero, Vinko Pandurevic, Ljubisa Beara, Vujadin Popovic, Drago Nikolic, Milorad Trbic, Ljubomir Borovcanin (IT-05-88-PT, Second Amended Indictment). Following the trial of General Krstic, a collaborative research project was developed between the Forensic Anthropology Center at The University of Tennessee (UT) and the United Nations, International Criminal Tribunal for the Former Yugoslavia, Office of the Prosecutor (ICTY). The purpose of that collaboration was to investigate methods used for the demographic analysis of forensic evidence and where appropriate to recalibrate methods for individual estimation of age, sex, and stature for specific use in the regions of the former Yugoslavia. The question of "local standards" and challenges to the reliability of current anthropological methods for biological profiling in international trials of IHL, as well as the performance of such methods to meet the evidentiary standards used by international tribunals is investigated. Anthropological methods for estimating demographic parameters are reviewed. An overview of the ICTY-UT collaboration for research aimed at addressing specific legal issues is discussed and sample reliability for Balkan aging research is tested. The methods currently used throughout the Balkans are discussed and estimated demographic parameters obtained through medico-legal death investigations are compared with identified cases. Based on this investigation, recommendations for improving international protocols for evidence collection, presentation, and research are outlined.  相似文献

Interview data from 45 matched pairs of survivors disclosing sexual assaults and their primary informal support provider (friend, family, significant other) were used to explore survivor-support provider perspectives on self-protective behaviors survivors and those close to them take to protect themselves from future assaults. Strategies for reducing risk taken by survivors included behavioral changes, security measures, self-defense strategies, avoiding alcohol or drugs, and protecting others. Support providers play critical roles by encouraging survivors to pursue risk avoidance strategies, and employing these strategies themselves. Counseling and prevention implications are drawn in the context of risks facing survivors trying to avoid further sexual victimization.  相似文献
