An Analysis of Forensically Important Insects Associated with Human Remains in Indiana,U.S.A.*

Research documenting insect colonization of human remains is limited in North America, and currently nonexistent for the American Midwest. Such research is essential for forensic entomologists to identify species of research interest in a region. In this study, we collected insects from human remains in 24 cases across Indiana from June 2016 through September 2018. We analyzed species composition across scene type and season. Eight species of blow flies were collected as larvae from human remains, with Phormia regina and Lucilia sericata as the two predominant colonizers. Phormia regina was the most numerous species collected from outdoor scenes (73.6% of total collections) while L. sericata was the most numerous from the indoor scenes (60.4% of total collections). With scene types pooled, Calliphora vicina and Cochliomya macellaria were the predominant species in the fall (55.6% and 42.2%, respectively); P. regina was the dominant colonizer in the spring (68.6%); and P. regina and L. sericata were the predominant colonizers (46.5% and 44.4%, respectively) in the summer. In addition to these findings, we confirmed the first record of Lucilia cuprina colonizing human remains in Indiana having collected this species from three cases. A single adult Chrysomya megacephala was collected from an indoor scene in southern Indiana, which represents its second collection in the state. Beetles belonging to the families Staphylinidae, Silphidae, Histeridae, Cleridae, Trogidae, Dermestdae, and Nitidulidae were also collected from two outdoor scenes. This study provides important baseline data for forensic entomologists in Indiana, as well as surrounding states with similar environments.     

Anticompetitive Employment

Scholars, antitrust agencies, and policy makers have historically paid little attention to anticompetitive practices in labor markets. This was largely due a misconception that antitrust law is meant to govern conventional markets in which goods and services trade, rather than govern labor markets. Antitrust law may also offer a poor remedy to redress employers who enter no-poaching agreements or otherwise impair competition. The primary tension involves antitrust's purpose, which is to promote “consumer welfare.” To identify whether conduct eroded consumer welfare, courts tend to scrutinize whether prices increased. But here, lessening wages can enable firms to sell goods at cheaper prices, benefiting consumers. Another issue is that the typical restraint affects only a smattering of workers instead of lessening wages throughout the greater market. This article uses empirical analyses to show that antitrust should promote labor's welfare as it does consumer welfare, and it argues that enforcement must condemn labor cartels as per se illegal. The research demonstrates that labor cartels are more pernicious than restraints in product markets, as employers can lessen wages with less effort than in product markets. Antitrust should even proscribe no-poaching agreements formed for a legitimate purpose (e.g., to protect trade secrets) because employers could have achieved the same goals using less coercive means; the noncompete agreement, at least, provides labor with a semblance of notice and bargaining power without drawing antitrust scrutiny. The prohibition of labor cartels would thus promote competition and consumer welfare, especially in minimum wage labor markets.     

Measuring the Difference Between Parental Alienation and Parental Estrangement: The PARQ-Gap

Parental alienation (rejection of a parent without legitimate justification) and realistic estrangement (rejection of a parent for a good reason) are generally accepted concepts among mental health and legal professionals. Alienated children, who were not abused, tend to engage in splitting and lack ambivalence with respect to their parents; estranged children, who were maltreated, usually perceive their parents in an ambivalent manner. The hypothesis of this study was that a psychological test—the Parental Acceptance–Rejection Questionnaire (PARQ)—will help to distinguish severely alienated from nonalienated children. The PARQ, which was used to identify and quantify the degree of splitting for each participant, was administered to 45 severely alienated children and 71 nonalienated children. The PARQ-Gap score—the difference between each child's PARQ: Father score and PARQ: Mother score—was introduced and defined in this research. Using a PARQ-Gap score of 90 as a cut point, this test was 99% accurate in distinguishing severely alienated from nonalienated children. This research presents a way to distinguish parental alienation from other reasons for contact refusal. The PARQ-Gap may be useful for both clinicians and forensic practitioners in evaluating children of separating and divorced parents when there is a concern about the possible diagnosis of parental alienation.     

Youth alcohol use and dating abuse victimization and perpetration: a test of the relationships at the daily level in a sample of pediatric emergency department patients who use alcohol

Objective: This study retrospectively examined the daily-level associations between youth alcohol use and dating abuse (DA) victimization and perpetration for a 6-month period. Method: Timeline Followback (TLFB) interview data were collected from 397 urban emergency department patients, ages 17 to 21 years. Patients were eligible if they reported past month alcohol use and past year dating. Generalized estimating equation (GEE) analyses estimated the likelihood of DA on a given day as a function of alcohol use or heavy use (≥4 drinks per day for women, ≥5 drinks per day for men), as compared with nonuse. Results: Approximately 52% of men and 61% of women participants reported experiencing DA victimization ≥1 times during the past 6 months, and 45% of men and 55% of women reported perpetrating DA ≥1 times. For both men and women, DA perpetration was more likely on a drinking day as opposed to a nondrinking day (ORs = 1.70 and ORs = 1.69, respectively). DA victimization was also more likely on a drinking day as opposed to a nondrinking day for both men and women (ORs = 1.23 and ORs = 1.34, respectively). DA perpetration and DA victimization were both more likely on heavy drinking days as opposed to nondrinking days (2.04 and 2.03 for men's and women's perpetration, respectively, and 1.41 and 1.43 for men's and women's victimization, respectively). Conclusions: This study found that alcohol use was associated with increased risk for same day DA perpetration and victimization, for both male and female youth. We conclude that for youth who use alcohol, alcohol use is a potential risk factor for DA victimization and perpetration.     

Tax incentives for innovation: time to restructure the R&;E tax credit

The R&E tax credit has never been effective and subsequent attempts to restructure it have not addressed the major deficiencies. Moreover, in the 25 years since the R&E tax credit was enacted, a steadily increasing number of countries have implemented or expanded competing tax incentives, which in many cases are better structured and larger in size. As a result, the relative impact of the US credit is now negative in terms of incentives to conduct R&D within the domestic economy. The inadequacy of the credit stems largely from its small size and its incremental format. The impact of an R&D tax incentive is affected by its scope of coverage, the ability of industry to take advantage of it over the entire R&D cycle, the magnitude of the incentive relative to other nations’ tax policies, and its ease of implementation. In the end, a tax incentive must sufficiently lower the user’s cost of R&D to overcome barriers to allocation of private-sector resources commensurate with the potential rates of return on such investments. As a policy instrument, a tax incentive for R&D should be most effective if its form is a flat rate applied to all R&D.

Why is basic service access worse in slums? A synthesis of obstacles

Many residents of urban areas face joint obstacles to basic service access, but these barriers are more prevalent and severe in slum settlements. Analyses of obstacles have typically been conducted in a piecemeal rather than synthetic framework and have focused on access to single services rather than the range of services needed to support household welfare. By contrast, this study uses data from fieldwork in four slum settlements situated in Hyderabad, India to develop a typology synthesising the obstacles – economic, spatial, social, institutional, and political – to the full range of service access desired by residents. Economic differences explain little of the access deficit within this population. While social and institutional obstacles are more likely to explain slum formation and residence over the long term, variation in spatial and political factors present the most acute short-term access barriers. The article concludes by suggesting the most promising means for slum residents and supporting stakeholders to overcome multi-faceted obstacles.
