Detection of organophosphate poisoning in a putrefying body by analyzing arthropod larvae

Deaths as a result of organophosphate poisoning are usually detected by analysis of body fluids and tissues for the presence of the toxic agent. These procedures present particular difficulties when performed on remains in an advanced stage of decomposition. Malathion poisoning was suspected in a case in which the remains were in an advanced stage of decomposition and the presence of malathion was confirmed by analyses of gastric content and body fat. Two species of fly larvae, Chrysomya megacephala (Fabricius) and Chrysomya rufifacies (Macquart), were present on the remains. A sample of these larvae was analyzed for malathion content. A total of 574 micrograms of malathion was detected in 0.26 g of pooled larvae, or a level corresponding to 2050 micrograms/g of larvae. Presence of organophosphates in arthropod larvae has not been documented previously and the analysis of larvae from decomposing remains may prove a useful technique for detection of these toxicants in decomposing remains.     

On the (mis)measurement of legislator ideology and shirking

In this paper, we show that current statistical measures of legislator's shirking are implicitly based on the electoral concept of a unique majority rule equilibrium point in the policy space where elections are contested. We note that such equilibria do not exist generically and present statistical results showing that cross-sectional regressions where legislators' voting indices are predicted by district average demograhic and economic data are mis-specified. We also discuss a weaker equilibrium construct, the uncovered set, and present statistical evidence showing that differences in voting behavior between Senators from the same state are positively related to the heterogeneity of the electorate. We argue that current evidence alleged to show shirking by Senators is equally consistent with Senators who perfectly represent an idiosyncratic constituency that cannot be represented by district average data.     

Policing alienated minorities in divided cities

Minority groups frequently challenge the legitimacy of legal authorities, particularly the police. Without trust and legitimacy, the police encounter constant conflict and cannot function effectively. While past research has examined minorities’ perceptions of the police, national minorities provide an interesting and under‐investigated test case because of their inherent identity conflict with the state. The current research examines three factors to explain minority–majority disparities in views of the police: (i) police effectiveness and fairness; (ii) intergroup discrimination (termed relative deprivation in policing); and (iii) identification with the state. Findings from a survey of Jewish and Arab residents of nationally mixed neighborhoods in Israel (n = 394) suggest that while all of these factors account for minority–majority discrepancies in views of the police, perceptions of police fairness are particularly important. Furthermore, feelings of discrimination and low levels of identification with the state are less important than evaluations of fairness in explaining minorities’ negative perceptions of the police.     

On creating ethical,productive, and durable research partnerships with police officers and their departments: a case study of the National Justice Database

ABSTRACT

Translational policing science must begin with explicitly communicated research aims and a shared vision for promoting safety. For researchers to approach police departments without first considering the concerns held by officers and their departments at large, is unethical, unproductive, and undermines efforts to secure longstanding mutually useful researcher-practitioner partnerships. In presenting a case study analysis of the multi-method National Justice Database’s recruitment practices, this article highlights some of the challenges that emerge when articulating study aims that hold relevance for public safety; defining theoretically- and solution-oriented research questions; administrative police data collection, analysis, and dissemination; and bolstering human research subject protection protocols for sworn officers who may be justifiably reluctant to participate in social science research endeavors. Implications for ethical policing research practice, fostering collaborative researcher-practitioner partnerships, and leveraging the benefits of data science are also discussed.     

“Why not love our language and our culture?” National rights and citizenship in Khrushchev's Soviet Union

This paper highlights campaigns for national rights among two non-titular communities in the Soviet Union and places them in local historical contexts. Drawing on archival sources and oral history interviews, the author not only delves into the campaigns themselves, but also explores broader debates about the nature of Khrushchev's Thaw and Soviet citizenship, which was far from an empty concept in the Khrushchev era. Petitioners invoked discourses that indicate both an awareness of national rights and an expectation of the state's obligation to protect them. Oral history interviews with surviving petitioners and community members support the notion that petition language can serve as a reflection of how petitioners viewed their place in Soviet society and interpreted the Soviet citizen contract.     

Supreme Court consensus and dissent: Estimating the role of the selection screen

From 1940 to the present, the on-the-record consensus among Supreme Court justices fell precipitously relative to historical benchmarks. This paper first shows that Court consensus is closely associated with measures of consistency and stability of Court rulings. Then, an empirical model of Supreme Court consensus and dissension is estimated over 1800–2001 in which characteristics of the presidential–senatorial screen are key variables. Using OLS and controlling for several other influences, the results show that variations in consensus are linked to two components of the selection screen – the party of the confirming Senate and split party nominations and confirmations. Other than the selection screen, the size of the federal judiciary and consensus norms in the recent past are important influences. These results are also confirmed using GARCH and regime-shifting econometric methods.
