In Europe, the blowfly genus Lucilia is represented in Forensic Entomology mainly by the species L. ampullacea, L. caesar, L. illustris and L. sericata. In the US, Lucilia silvarum is rarely recorded as a carrion breeding species but usually as a more or less exclusive parasite of frogs and toads. We present three forensic cases from different European countries reporting, for the first time, L. silvarum on human bodies that were found close to lakes, wetlands, or riversides. To use this species for post-mortem interval estimations, thermal development data is needed. The first step is accurate identification by morphological and molecular means. Therefore, we analysed a 611bp part of the mitochondrial COI region for 23 specimens of L. silvarum from 9 different geographical regions, all of which give the same haplotype. Differences within the haplotype varied by up to 0.2%. Comparison between the haplotype found and those published on GenBank showed up to 1.2% variance. Moreover, we present an updated key for the morphological identification of the third larval instars of European Lucilia spp. of forensic importance, adding not only L. silvarum, but also L. cuprina which was recorded in Europe for the first time about 20 years ago. 相似文献

This study empirically investigates the extent of noncompliance with the tax code and examines the determinants of federal
income tax evasion in the U.S. Employing a refined version of Feige’s (Staff Papers, International Monetary Fund 33(4):768–881,
1986, 1989) General Currency Ratio (GCR) model to estimate a time series of unreported income as our measure of tax evasion, we find
that 18–23% of total reportable income may not properly be reported to the IRS. This gives rise to a 2009 “tax gap” in the
range of $390–$390–540 billion. As regards the determinants of tax noncompliance, we find that federal income tax evasion is an
increasing function of the average effective federal income tax rate, the unemployment rate, the nominal interest rate, and
per capita real GDP, and a decreasing function of the IRS audit rate. Despite important refinements of the traditional currency
ratio approach for estimating the aggregate size and growth of unreported economies, we conclude that the sensitivity of the
results to different benchmarks, imperfect data sources and alternative specifying assumptions precludes obtaining results
of sufficient accuracy and reliability to serve as effective policy guides. 相似文献

Child sexual abuse (CSA) often requires psychological treatment to address the symptoms of victim trauma. Barriers to entry and completion of counseling services can compromise long-term well-being. An integrated medical and mental health evaluation and treatment model of a child advocacy center (CAC) has the potential to reduce barriers to mental health treatment. Objective: (a) to describe characteristics between CSA patients who engage versus those who do not engage in mental health treatment and (b) to identify factors associated with successful completion of mental health treatment goals. For design/setting, a retrospective cohort study was conducted of CSA patients (ages 3-16 years) referred to mental health services following a CAC assessment. Outcome variables included linkage with treatment and completion of treatment. Independent variables included demographics, abuse characteristics, and therapist characteristics. Data were abstracted from the CAC and billing databases. Results: Four hundred ninety subjects were evaluated. Subjects were as follows: predominately female (74%), White (60%), and more than half received Medicaid (56%). Mean age was 8.4 years. About 52% linked with mental health services and 39% of patients that successfully linked with mental health services completed therapy. Successful linkage was independently associated with referrals to other counseling services (AOR 8.4 [2.5, 27.7]). Successful completion of therapy was independently associated with caregiver participation in therapy (AOR 3.2 [1.8, 6.0]) and if the patient was referred to other counseling services (AOR 4.1 [1.9, 8.5]). There were no differences between subjects that linked and/or completed therapy and those that did not with regard to demographic characteristics or abuse severity. Conclusion: In contrast to previous reports, efforts at our CAC seem to overcome linkage barriers in this population. However, there remain challenges in achieving successful completion of treatment goals in this population. Engaging caregivers' involvement in therapy services had a positive effect with successfully achieving treatment goals. 相似文献

Using stochastic methods we illustrate that the Provisional Irish Republican Army's (PIRA) network is clustered along three primary dimensions: (a) brigade affiliation, (b) whether the member participated in violent activities, and (c) task/role within PIRA. While most brigades tended to foster connections within the brigade (that is, “closure”), the tendency to do so varied across the organization. Members who engaged with violent activities were far more likely to connect with each other; in later periods there is polarization into those who engage in violent activities and those who do not. Across brigades, those who engage in a particular task and role (improvised explosive device [IED] constructor, IED planter, gunman, robber/kidnapper/drug smuggler/hijacker) are more likely to connect with others who do the same task or play the same role than with other members who fulfill other roles. Standard forms of homophily (that is, the tendency to make connections with people who are similar in terms of demography or status) play a very weak role in explaining which members interact with one another. Finally, our analysis illustrates clear patterns of relational change that correspond to changes in the formal structures that PIRA's leadership promoted. 相似文献

In this introduction to the special issue on ‘Women's work in changing labour markets’, we argue that a combination of digital advances, notably the digitization of individual- and contextual-level data, the creation of internationally comparable occupation-based classifications, and the development of statistical models allowing for contextually informed analysis, has brought us to the brink of new developments in the field of women's work. Census and vital registration data contain more information on occupations of women than previously thought, and when used in combination with other digitized sources they allow one to assess the possible under-registration of women's work, as illustrated by some of the contributions to this special issue. Other contributions show how standardizing occupation-based classifications allows for temporal and regional comparisons of women's work and makes it feasible to study how community or regional characteristics influence that work. None of these developments – large-scale digitization of individual-level data, standardization of occupational titles and measures of stratification, and contextually informed analyses – is completely new; in some cases they are actually rooted in a venerable research tradition. However, in combination they might well constitute a cascade in the history of working women. 相似文献

In the 2009 case of R. v. Grant, the Supreme Court of Canada reformulated the exclusion of evidence framework in the context of Charter breaches. The case was something of a revolution for those who study evidence law and the Charter. Thus far, the case has been the subject of much debate and even empirical study. Few academic papers have explored the philosophical predilections of the Court in the decision. In this paper, the authors briefly review the history of the exclusion of evidence test, explain the new framework and discuss the academic and legal responses to the case. The authors place the reasoning of the Court in a broader socio-legal context arguing that the test articulated by the Court is informed by a type of populism that combined with recent Charter cases in the police powers context allows for flexible potentials, ones that could, on occasion, encroach on due process protections. The authors call for scholars and activists to keep a close eye on the emerging jurisprudence in this critical area of Charter adjudication. 相似文献

This article analyzes the sociodemographic network characteristics and antecedent behaviors of 119 lone‐actor terrorists. This marks a departure from existing analyses by largely focusing upon behavioral aspects of each offender. This article also examines whether lone‐actor terrorists differ based on their ideologies or network connectivity. The analysis leads to seven conclusions. There was no uniform profile identified. In the time leading up to most lone‐actor terrorist events, other people generally knew about the offender's grievance, extremist ideology, views, and/or intent to engage in violence. A wide range of activities and experiences preceded lone actors' plots or events. Many but not all lone‐actor terrorists were socially isolated. Lone‐actor terrorists regularly engaged in a detectable and observable range of activities with a wider pressure group, social movement, or terrorist organization. Lone‐actor terrorist events were rarely sudden and impulsive. There were distinguishable behavioral differences between subgroups. The implications for policy conclude this article. 相似文献
