Printed artificial sweat as replacement for natural fingermarks: Qualitative and quantitative approach considering an amino acid reagent

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.     

Advancing police use of force research and practice: urgent issues and prospects

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.     

Is Leadership in the Eye of the Beholder? A Study of Intended and Perceived Leadership Practices and Organizational Performance

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.     

The Politics of Local Government Stabilization Funds

The adoption, maintenance, and prudent use of budgetary stabilization funds are fundamental financial management precepts, yet the variables that influence the size of these funds are poorly understood. This article contributes to the stabilization fund literature by examining the extent to which variation in stabilization fund balances across municipalities and over time can be explained by a community's political culture and financial management capacity. The balanced panel research design includes archival data for 239 Massachusetts municipalities for each of 18 fiscal years. Stabilization fund balances are lower in communities with either an anti‐tax or a pro‐spending political culture. Stabilization fund balances are higher in communities that have the financial management capacity to accumulate budget surpluses that can be made available for appropriation to stabilization funds. Communities with the open town meeting form of government also have higher stabilization fund balances.     

Incrementalism: Dead yet Flourishing

Charles Lindblom's 1959 essay “The Science of ‘Muddling Through’” is best known for the strategy of decision making—disjointed incrementalism—that it recommended. That famous paper and Lindblom's related work also provided two theories: a critique of the conventional method (the synoptic approach) and an argument for using incrementalism instead. Both are applied theories: they are designed to help solve complex policy problems. Lindblom's negative applied theory has stood the test of time well: the empirical foundations of its main micro‐component (cognitive constraints of individuals) and its central macro‐component (the impact of preference conflict on policy making) have grown stronger since 1959. The picture regarding the positive applied theory is more mixed. As a coherent decision‐making strategy, disjointed incrementalism has almost disappeared. Yet its key elements, the major heuristics identified in “Muddling Through,” are thriving in many applied fields. Intriguingly, they are often accompanied by subroutines—especially optimization as a choice rule—typically associated with the synoptic approach.     

Guerrilla Statesmanship: Constitutionalizing an Ethic of Dissent

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.     

Women Don't Run? Election Aversion and Candidate Entry

To study gender differences in candidate emergence, we conduct a laboratory experiment in which we control the incentives potential candidates face, manipulate features of the electoral environment, and measure beliefs and preferences. We find that men and women are equally likely to volunteer when the representative is chosen randomly, but that women are less likely to become candidates when the representative is chosen by an election. This difference does not arise from disparities in abilities, risk aversion, or beliefs, but rather from the specific competitive and strategic context of campaigns and elections. Thus, we find evidence that women are election averse, whereas men are not. Election aversion persists with variations in the electoral environment, disappearing only when campaigns are both costless and completely truthful.     

The Impact of Home‐Based Child Care Provider Unionization on the Cost,Type, and Availability of Subsidized Child Care in Illinois

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.
