Entomological protocols for aging blowfly (Diptera: Calliphoridae) larvae to estimate the time of colonization (TOC) are commonly used to assist in death investigations. While the methodologies for analyzing fly larvae differ, most rely on light microscopy, genetic analysis, or, more rarely, electron microscopy. This pilot study sought to improve resolution of larval stage in the forensically important blowfly Chrysomya rufifacies using high‐content fluorescence microscopy and biochemical measures of developmental marker proteins. We established fixation and mounting protocols, defined a set of measurable morphometric criteria and captured developmental transitions of 2nd instar to 3rd instar using both fluorescence microscopy and anti‐ecdysone receptor Western blot analysis. The data show that these instars can be distinguished on the basis of robust, nonbleaching, autofluorescence of larval posterior spiracles. High‐content imaging techniques using confocal microscopy, combined with morphometric and biochemical techniques, may therefore aid forensic entomologists in estimating TOC. 相似文献

Legitimacy-based approaches to crime prevention assume that individuals will comply with the law when they believe that the law and its agents are legitimate and act in ways that are “fair” and “just.” Currently, legitimacy-based programs are shown to lower aggregate levels of crime; yet, no study has investigated whether such programs influence individual offending. Using quasi-experimental design and survival analyses, this study evaluates the effectiveness of one such program—Chicago’s Project Safe Neighborhoods’ (PSN) Offender Notification Forums—at reducing individual recidivism among a population of returning prisoners. Results suggest that involvement in PSN significantly reduces the risk of subsequent incarceration and is associated with significantly longer intervals that offenders remain on the street and out of prison. As the first study to provide individual-level evidence promoting legitimacy-based interventions on patterns of individual offending, out study suggests these interventions can and do reduce rates of recidivism. 相似文献

The purpose of our study has been to better estimate the number and types of crimes committed by asylum seekers and irregular migrants. While data on immigration status for non-residents are lacking in Norwegian crime statistics, we use indirect identifiers (lack of a national ID number, citizenship, residency) to arrive at an estimate for persons with a pending asylum claim and the related group of irregular migrants (i.e. non-EU citizens). A very small amount of the total crimes registered with a known offender are committed by this group. However, these groups are most likely overrepresented as offenders compared to the registered resident population, also when taking age and gender into consideration. Our method is recommended in a field otherwise dominated by political arguments and as an alternative to registering asylum status in crime registers. 相似文献

This study examines macro-level variation in juvenile theft and burglary arrest rates using a sample of 127 large cities in the United States. Independent variables were drawn from routine activities theory and included measures of guardianship (e.g., portion of families with both parents working, police to resident ratio, etc.), the number of motivated offenders (e.g., portion of the population under age 18), and the availability of suitable targets (e.g., poverty rates). Both ordinary least squares and weighted least squares regression analyses were performed. These analyses found that the significant predictors varied between burglary and theft. Additionally, there were differences in the predictors which significantly affected the arrest rates of male and female juveniles. However, within each offense the models explained similar portions of the overall variation in arrests for both genders. 相似文献

This article presents a longitudinal examination of the association between children's experiences of child maltreatment (CM) and intimate partner violence (IPV), alone and in combination, with children's academic performance. Integrated, administrative data from the Minnesota Departments of Education and Human Services were used to obtain a sample of 2,914 children. Data provided an opportunity to study comparisons of single (CM or IPV) and combined experiences (CM-IPV), longitudinally observe the impact of these experiences on academic functioning, and make comparisons to the general population. Results revealed significant differences in school attendance and math and reading performance by adverse experience. Children exposed to CM and IPV, individually or in combination, underperformed at school. IPV-exposed children had the poorest outcomes. Findings highlight the need for dedicated screening for adverse childhood experiences, particularly IPV exposure, and devoting greater educational and social service resources as a means of promoting future school achievement and adult functioning. 相似文献

This research tests whether the effects of assessments of presidential performance on the senate voting decision are largest for out-party incumbents and smaller for out-party incumbents and candidates in open-seat contests, a pattern suggested by the restricted in-party culpability thesis. Analysis of data from the 1988–1990–1992 Pooled Senate Election Study reveals that the effects of appraisals of presidential performance are greatest in open-seat contests and those with in-party incumbents, contrary to the restricted in-party culpability thesis. For incumbents of the out-party and candidates in open-seat contests, the effects of assessments of presidential performance are principally a function of the competitiveness of the contest. Assessments of presidential performance shape the voting decision in contests with in-party incumbents regardless of the level of electoral competitiveness. 相似文献

Whereas the classic literature on strategic voting has focused on the dilemma faced by voters who prefer a candidate for whom they expect has little chance of winning a seat, we consider the dilemma faced by voters in PR systems who do not expect their preferred party to be in government. We develop hypotheses relating to strategic voting over multi-party governments that we test using the New Zealand Election Study (NZES) campaign study of 2002. We find evidence that expectations play a role in structuring vote choice. While there is clear evidence of wishful thinking there is also evidence that voters respond to expectations about government formation. These expectations may mobilize voters and lead them to defect from their first preference. 相似文献

Coalition governments are the norm in parliamentary democracies. Yet, despite the predominance of this type of government, political scientists have only recently started to investigate how voters approach elections when a coalition government is the likely outcome. Such elections present additional uncertainty and complexity for voters compared with elections in plurality systems, where party choice translates more directly into a choice of government. These factors have lead to the assumption that strategic voting is unlikely to occur in systems that produce coalition governments. In this introductory article to the special issue on Voters and Coalition Governments, we consider whether voters have the capacity to anticipate specific coalition outcomes and propose a framework for understanding the conditions that lead to strategic voting in both plurality and proportional systems. 相似文献

Just over a decade since the failed referendum of 1998, statehood for the Northern Territory (NT) is back on the political agenda. The achievement of statehood would be a first for Australian federalism, where no new state has been created or admitted since Federation. Following a discussion of the concept of statehood and how it might be achieved, it traces the political development of the NT. The article then examines the implications of NT statehood for the Australian federation and finds that statehood would facilitate constitutional change in the federation by lowering the threshold required for success in a national referendum. Statehood may also raise questions about the equal representation in the Senate of less populous states. However, statehood would have no effect upon financial arrangements with the Commonwealth, the standing of the Northern Territory at COAG meetings, or the legal standing of the other states. 相似文献
