Further observations on the nocturnal oviposition behaviour of blow flies (Diptera: Calliphoridae).

Calculating the age of immature stages of blow flies showing the longest period of association with a dead body often gives a fairly accurate estimate of the post-mortem interval (PMI). Determination of the exact time of oviposition by these flies had generally been made in the light of the conventional belief that blow flies are neither active nor do they lay eggs during night. This method of estimating the time of oviposition was modified when Greenberg [J. Med. Entomol. 27 (1990) 807] reported nocturnal oviposition by three calliphorid species that are occasionally used as forensic indicators. However, a technical problem with his experiment, having long term consequences, was placement of the bait on the ground among bushes. This could have made it possible for the flies already resting near the bait to climb over the piece of meat and lay eggs. Though Greenberg's experiment proves beyond any doubt that blow flies do lay eggs at night as well as by day, active attraction of these flies at night towards the oviposition medium had yet to be proved and the present experiment has been designed for this purpose.     

Facial soft tissue thickness in northwest Indian adults

In order to reconstruct the face from a bare skull, the facial soft tissue thickness (FSTT) was determined at 29 standard anthropological landmarks by magnetic resonance imaging (MRI) in 173 male and 127 female adult subjects of northwest Indian origin. Repeatability and accuracy of the measurements was assessed by paired t-test and 95% confidence intervals. A stepwise discriminant function analysis selected nine landmarks for better sex classification in FSTT measurements. The thickness of soft tissue was different from that described in the literature and reported for samples from other countries. A correlation between skinfold thickness and body mass index (BMI) with that of FSTT was observed. The data of facial soft tissue thickness will help forensic experts in reconstructing the face from a skull for identification purposes.     

A test of individuality of human external ear pattern: its application in the field of personal identification

A preliminary study has been undertaken to test the individuality of human ear patterns and its probable use in profile view facial image recognition. Anthropometric measurements on 12 inter-landmark linear distances have been carried out for both left and right ears of 700 male and female individuals. A 12-dimensional feature space has been framed to represent each ear pattern as a feature vector with the measured inter-landmark distances as its components. The Euclidean distances in such a feature space amongst all possible pairs of ear patterns of both male and female individuals have been computed. Very few pairs have distances which fell below the safe distinction limit. The undistinguished pairs were further examined by direct superimposition of their images. None of the ear patterns is found to be exactly the same in morphology to the other. Even the left and right ears of the same individual are not identical. Thus, the present study reconfirms the individuality of ear patterns. For establishment of identity, a questioned profile view facial image can be compared with a control one on the basis of the ear pattern visible in it.     

A Decision Theoretic Model of Public Opinion: Guns, Butter, and European Common Defense

Why do individuals support the public policies they do? We argue that individuals can have quite sophisticated policy preferences and that not correctly modeling those preferences can lead to critically misspecified empirical models. To substantiate this position we derive and test a decision‐theoretic model that relies upon three critical assumptions: (1) policies affect the provision of multiple goods about which individuals care; (2) individuals have diminishing returns to scale in those goods; and (3) preferences over at least some subset of those goods are correlated. Using this model, we demonstrate that arbitrarily small secondary policy effects can confound predictions over primary policy effects. Thus, not considering even arbitrarily small policy effects can cause one to conclude that evidence is consistent with one's theory when in fact it is inconsistent or vice versa. Testing this theory on support for forming a European common defense, we find evidence consistent with our model.     

Field experiments on the competitiveness of males carrying genetic control systems for Aedes aegypti

The competitiveness carrying males of three genetic control systems forAedes aegypti (L.), viz. chemosterilized males, double translocation heterozygote males (T1T3) and distorter double translocation heterozygote males (DT1T3), released into a natural population in the Delhi metropolitanxarea was evaluated using a method based on the principle of release and recapture of marked females. Chemosterilized males and DT1T3 males showed approximately normal competitiveness in the field which is similar to the results obtained from laboratory and field cage experiments. The T1T3 males were found to have reduced competitiveness both in the field and laboratory cage tests, in contrast to previously reported results with unmarked T1T3 males in field cages. The cause of this reduction in competitiveness was not clear.

Zusammenfassung Es wurde die Konkurrenzkraft vonAedes aegypti — M?nnchen ermittelt nach Anwendung von drei genetischen Verfahren, n?mlich Chemosterilisation der M?nnchen, heterozygote doppelte Translokation (T1T3) und gest?rte doppelte heterozygote Translokation (DT1T3) der M?nnchen, die in eine natürliche Population des hauptst?dtischen Gebiets von Delhi freigelassen wurden; dabei wurde eine auf dem Prinzip des Freilassens und Wiederfangs von markierten Weibchen beruhende Methode verwendet. Chemosterilisierte und DT1T3 — M?nnchen zeigten ann?hernd normale Konkurrenzkraft, was den Ergebnissen von Labor- und Freilandk?figversuchen entspricht. Die T1T3-M?nnchen zeigten verminderte Konkurrenzkraft im Feld und in Labork?figtests, im Gegensatz zu früher berichteten Befunden mit nicht-markierten T1T3-M?nnchen in Feldk?figen. Die Ursache dieser Reduktion der Konkurrenzkraft war nicht klar.

     

Coping with Work Stress in Police Employees

Present study endeavored to investigate the role of coping in work stress of police employees. A 3 × 2 factorial design with three levels of job hierarchy (officers, sub-inspectors, and constables) and two levels of job tenure [short job tenure (0–10 year) and long job tenure (above 10 year)] was used in present study. A total of 240 police personnel from Gorakhpur Zone (India) participated as respondents. Objective Work Stress Scale, Feeling of Work Stress Scale (Cooper 1983), and Coping Scale (Carver et al. 1989) were used to determine the level of work stress and coping of the police employees. ANOVA results revealed that the level of work stress varied across different groups of police personnel. More specifically, objective work stress was found greater in sub-inspectors than constables and officers while constables reported more feeling of work stress than sub-inspectors and officers, respectively. Furthermore, the different groups of police personnel differed on various forms of coping response, in which officers used more active- and adaptive-related coping strategies than sub-inspectors and constables, respectively. Contrary to this, constables used more maladaptive coping strategies than sub-inspectors and officers. Correlation results evinced that active- and adaptive-related coping responses have an inverse link with work stress, whereas maladaptive coping responses have a positive relationship with work stress. Findings have been discussed in the light of organizational and personal factors.     

Simulated evidence on the prospects of treating more drug-involved offenders

Despite a growing consensus among scholars that substance abuse treatment is effective at reducing offending, strict eligibility rules and budgetary considerations greatly limit the impact that current models of therapeutic jurisprudence can have on public safety in the United States. A question of pressing importance for U.S. drug policy is whether it is beneficial to expand application of this model to treat every offender in need and, if so, whether a set of evidence-based, going-to-scale strategies can be developed to prioritize participation. We use evidence from several sources to construct a synthetic dataset for answering the question: What are the benefits we can reasonably expect by expanding treatment to drug-involved offenders? We combine information from the National Survey on Drug Use and Health (NSDUH) and the Arrestee Drug Abuse Monitoring (ADAM) program to estimate the likelihood of various arrestee profiles having drug addiction or dependence problems. We use the same sources to also develop prevalence estimates of these profiles among arrestees nationally. We use information in the Drug Abuse Treatment Outcome Study (DATOS) to compute expected crime-reducing benefits of treating various types of drug-involved offenders under different treatment modalities. We find that annually nearly 1.5 million (probably guilty) arrestees in the U.S. are at risk of abuse or dependence and that treatment alone could avert several million crimes that these individuals would otherwise commit. Results vary by treatment modality and arrestee traits and those results are described herein.     

Comparative Vigilance

A growing body of literature suggests that courts and juriesare inclined toward division of liability between two strictlynon-negligent or "vigilant" parties. In this paper, we explorethe economic efficiency of liability rules based on comparativevigilance. We devise rules that are efficient and that rewardvigilance. Commonly used liability rules have discontinuousliability shares. We develop a liability rule, which we callthe "super-symmetric rule," that is both efficient and continuous,that is based on comparative negligence when both parties arenegligent and on comparative vigilance when both parties arevigilant, and that is always responsive to increased care.     

Conceptualizing and Measuring Ethnic Politics: An Institutional Complement to Demographic, Behavioral, and Cognitive Approaches

The influence of ??ethnic politics?? has been demonstrated in a range of empirical studies of economic growth, violence, and public goods provision. While others have raised concerns about the measurement of ethnic variables in these works, we seek to situate such discussions within a more thoroughgoing conceptual analysis. Specifically, we argue that four conceptual approaches??demographic, cognitive, behavioral, and institutional??have been used to develop theories in which the mechanism that relates causes to outcomes is ethnic political competition. Within this literature, we believe that institutional approaches have been relatively under-appreciated, and we attempt to address that imbalance. We begin by critically reviewing the three main ways in which ethnic variables have been specified and operationalized, delineating the assumptions and trade-offs underlying their use. Next, we describe an institutional approach to the study of ethnic politics, which focuses on the rules and procedures for differentiating ethnic categories. We propose some new indices based on this latter approach that might be developed and used in future research. Subsequently, we analyze the relationship between each of these approaches and patterns of ethnic political competition in a set of six country cases, highlighting their strengths and weaknesses, as well as theoretical links between them.     

Disseminated Neonatal Herpes Simplex Virus Infection with Escherichia Coli Coinfection

Neonatal herpes simplex virus (HSV) infection is an uncommon disease that rarely presents as sudden unexpected death of a previously healthy newborn. Clinical manifestations are variable; signs and symptoms may be subtle and nonspecific. Neonatal infection may present with mucocutaneous (skin, eye, and/or mouth), disseminated, or central nervous system disease. Morbidity and mortality are dependent upon disease presentation and treatment. The infection is most frequently transmitted during the peripartum period, although the majority of mothers have no known history of HSV infection at the time of delivery. Findings at autopsy include gastrointestinal or mucocutaneous ulcers, diffuse hepatic necrosis, adrenal necrosis, pneumonitis, and splenic necrosis. Characteristic intranuclear viral inclusions are identified on microscopic examination. Coinfection with bacterial organisms may contribute to death. Autopsy examination with appropriate ancillary studies, including cultures, is critical given that many infants lack cutaneous manifestations of disease and remain undiagnosed prior to death.
