The study presented in this paper aims at assessing how printed fingermarks can be used to generate realistic latent marks bearing varying quantities of materials to be detected. Considering dilution series of artificial sweat (eccrine secretion) and 1,2-indanedione/zinc as amino acid reagent, we assessed how printed marks behave in comparison to natural fingermarks provided by a set of 30 donors. The results were assessed in terms of relative intensity (contrast, luminescence) and expert grading (ridge details, overall quality). With regards to the set of 30 donors, this study brought a quantitative look to the influence of intra- and inter-variability on the relative intensity values observed when processing natural fingermarks. This provided new data to further understand the concept of “donorship”. With regards to the use of printed marks, it has been illustrated how dilution series of a concentrated solution allows covering a range of cases: unnatural marks (intensity values well above those obtained with donors), rich marks (corresponding to fingermarks left by good donors), and faint marks (associated with the kind of results observed with poor donors). Such a range of detection performance offers the possibility to generate fine-tuned detection exercises of varying difficulty levels. Printed items made of artificial sweat could hence constitute a valuable alternative to natural secretions in the context of education and proficiency testing. 相似文献

Leading police scholars and practitioners were asked to reflect on the most urgent issues that need to be addressed on the topic of use of force. Four themes emerged from their contributions: use of force and de-escalation training needs to improve and be evaluated; new ways of conceptualizing use of force encounters and better use of force response models need to be developed; the inequitable application of force, and how to remediate biases, needs to be more fully understood; and misconceptions about police use of force need to be identified and corrected. The highlighted topics serve as an agenda for future research. Such research should provide greater insight into when, where, and why force is used by police officers, and how it can be applied appropriately. If implemented, the practical recommendations included in the contributions should have a positive impact on police performance, public trust and confidence in the police, and citizen and officer safety. 相似文献

Is Leadership in the Eye of the Beholder? A Study of Intended and Perceived Leadership Practices and Organizational Performance 下载免费PDF全文
Leadership is a matter of both intentions and perceptions, which do not necessarily always match. Because employees’ motivation and commitment are only affected by leadership if they notice it, employee‐perceived leadership is expected to have a stronger correlation with organizational performance than leader‐intended leadership. This expectation is tested for transformational and transactional leadership, as both types of practices are expected to increase performance. Using a sample of 1,621 teachers and 79 Danish high school principals, the authors find that leader‐intended and employee‐perceived transformational and transactional leadership are only weakly correlated and that only employee‐perceived leadership practices (both transformational and transactional) are significantly related to objectively measured school performance. The results show that it is important to distinguish between intended and perceived leadership and that leaders should be aware of how their practices are perceived. 相似文献

According to judicial precedents, administrators informed by their expertise can speak on issues of public concern under First Amendment protections. In one sense, they could dissent by working against their employers in an attempt to direct issues of public concern through an educational function. The power to act like a statesman in raising such issues allows administrators to lead from behind and in front, as long as certain judicial thresholds are met. However, the U.S. Supreme Court recently moved to tighten the scope of such activity. This article assesses how an ethic of dissent has been translated into a constitutional perspective that at first was moderately constrained and later became very restricted. While the move to limit an ethic of dissent provides necessary constraints, it also may have weakened administrators’ ability to perform necessary statesmanship acts rooted in guerrilla government to achieve the common good. 相似文献

The Impact of Home‐Based Child Care Provider Unionization on the Cost,Type, and Availability of Subsidized Child Care in Illinois 下载免费PDF全文
Todd Grindal Martin R. West John B. Willett Hirokazu Yoshikawa 《Journal of policy analysis and management》2015,34(4):853-880
In February 2005, Illinois became the first U.S. state to grant home‐based child care providers (HBCPs) the right to form a labor union in order to bargain collectively with the state government. This policy inspired similar efforts across the country and represents a potentially important direction for child care policy. To date, the implications of labor unions for the cost, type, and availability of subsidized child care have not been evaluated empirically. In this study, we examine the impact of granting Illinois HBCPs the right to form a labor union on (a) the type of child care (licensed vs. license‐exempt/home‐based vs. center‐based) used by subsidy‐receiving Illinois infants and toddlers; (b) the per‐child cost of subsidized child care for infants and toddlers; and (c) the percentage of Illinois infants and toddlers who use child care subsidies. To conduct these analyses, we combine data from the Current Population Survey with Child Care and Development Fund administrative records on U.S. infants and toddlers whose families received child care subsidies during the period from 2002 to 2008. We use both a traditional difference‐in‐differences as well as a comparative case study with a “synthetic” control group approach. The synthetic control group approach improves on traditional comparative case studies by providing a transparent, empirical approach for constructing the counterfactual, documenting comparison units’ contribution to the synthetically created control group and detailing the degree to which the synthetic control group is, or is not, similar to the treated unit on preintervention measures of the outcome as well as on other selected characteristics. We find that subsidy‐receiving Illinois infants and toddlers spent an average of between 6.4 and 7 percentage points more hours in licensed care settings, as compared to license‐exempt settings, in the three years following child care unionization. We also find that between 0.7 and 1.1 percentage points fewer Illinois infants and toddlers used child care subsidies following unionization. 相似文献

AbstractThis article takes an unlikely approach to thinking about intersectionality theory. Exploring key concepts from the writings of Hannah Arendt, such as plurality, conscious pariah, and statelessness, alongside her embodied interrogation of anti-Semitism and the Jewish Question, it suggests a way to transgress the ordinary boundaries of the concepts of queer, international, and feminist and, conversely, to unbound the ordinary ways Arendt’s theories have been interpreted as less relevant, if not antithetical to, feminist, intersectional, and queer theories and politics. 相似文献

Sexual offenses represent an alarming proportion of crimes committed yearly. To address these concerns, several states, including South Carolina (SC), have enacted laws requiring sexually violent predators (SVPs) to be civilly committed to treatment. To date, no published study has examined sexual offenders recommended for treatment in SC. This study used a specially designed statewide database (SC-SVP research database) to determine which offender and offense characteristics were associated with increased likelihood of being recommended for civil commitment. Factors correlated with being more likely to be recommended included: being of a younger age at time of evaluation, prior sex convictions, having related and unrelated victims, a higher number of victims, frequent substance use, and a history of suicide attempts. Prior sex convictions, having both related and non-related victims, and a higher total number of victims align with characteristics associated with sexual recidivism. Frequent substance abuse and a history of suicide attempts do not mirror previous findings regarding sexual recidivism. These findings present new information regarding the civil commitment process of offenders being committed to the SC-SVP treatment program, characterize types of offenders committed to SC-SVP treatment program, and provide a foundation for using a computerized database in conducting sex offender research. 相似文献

As is clear from the historiography of the US decision to use the atomic bomb on Hiroshima, the judgments of historians are relative to the time, place, and perspective from which they are writing. There are four major schools of historical interpretation of the decision. First is the orthodox view that was offered by the participants in the decision. Second is the revisionist view of historians writing during the era of the Vietnam war who adopted a much more critical interpretation. Third is an interpretive school that gives weight to the Japanese role and responsibility. Finally, the author's view is found in a more long-range perspective that finds the momentum created by President Roosevelt's unconditional surrender policy as the decisive factor. This policy provoked unconditional resistance in the Japanese military. By 1945 the legacy of Roosevelt's policy was firmly embedded in American public opinion. Historians have reached no consensus among these different interpretive schools. 相似文献
