Social Influences on Online Political Information Search and Evaluation

Americans are turning to the Internet to learn about politics in greater and greater numbers. Under the current “Web 2.0” paradigm in which users are encouraged to interact with online content, voters encountering political information on the Internet are typically exposed to more than just the news; online information is often colored by the reactions of previous readers, whether in the form of displayed comments or in readily apparent tallies of the number of “likes” or “shares” a particular item has received. In this paper we consider the effect these social cues have on online political information search and evaluation. Using processing-tracing software to monitor the patterns of information search and evaluation among our subjects, we find that social cues can function as a heuristic, allowing voters to reach judgments similar to those of their more informed counterparts. However, we also find that negative cues can adversely influence candidate evaluation, making subjects less disposed to a candidate than they would be in the absence of such signals.     

Development and Implementation of an Effective Blind Proficiency Testing Program

Blind proficiency testing is ideal for testing crime laboratory personnel because the elements of analyst bias and anticipation are removed. However, sending proficiency tests through the laboratory system as real casework is difficult. The substantial challenges with preparing and administering blind tests may prevent laboratory managers from initiating blind testing. In 2015, the Harris County Institute of Forensic Sciences committed to improving its crime laboratory’s proficiency testing program by adding blind tests. The goal was to test the whole system, from evidence receipt to report release. With careful planning, trial-and-error, and ongoing assessment of available resources, not only was the program proven to be feasible, but there was also clear understanding of how to optimize our program. In this article, we share our experiences, lessons learned, and program details to assist other forensic service providers with developing their own blind testing programs, which would ultimately lead to improved quality assurance.     

The Psilocin (4-hydroxy-N,N-dimethyltryptamine) and Bufotenine (5-hydroxy-N,N-dimethyltryptamine) Case: Ensuring the Correct Isomer has Been Identified

Psilocin (4-hydroxy-N,N-dimethyltryptamine, 4-HO-DMT) and bufotenine (5-hydroxy-N,N-dimethyltryptamine, 5-HO-DMT), which are both naturally occurring compounds, are classified as controlled substances in numerous countries due to their pharmacological activities and recreational usage. There are two other benzene ring regioisomers, 6-hydroxy-N,N-dimethyltryptamine (6-HO-DMT) and 7-hydroxy-N,N-dimethyltryptamine (7-HO-DMT), which are not classified by name as controlled substances, and which were synthesized for this current work. The four isomers were analyzed using routine methodologies employed by the Israel's Police Division of Identification and Forensic Science (DIFS) Laboratory, namely thin layer chromatography (TLC), Fourier transform infrared spectroscopy (FTIR), and gas chromatography mass spectroscopy (GC-MS). It was found possible to differentiate the four isomers. Forensic specimens that were suspected to be psilocybe mushrooms were examined, confirming that it is now possible to unequivocally identify the presence of psilocin and rule out the presence of its other isomers.     

The ‘Heathrow’ Case: Polycentricity,Legislation, and the Standard of Review

The recent Court of Appeal decision in the ‘Heathrow’ case, Plan B Earth v Secretary of State for Transport is an illustration of the challenges of reviewing polycentric and expert decision-making. The issues raised in the case concerning the Planning Act 2008 are an illustration of a court's expository role in such contexts. The Court tackled directly a series of interpretive questions concerning the Planning Act 2008's obligations regarding the consideration of climate change. The Habitats and Strategic Environmental Assessment (SEA) Directive issues raised in the appeal, in contrast, were presented with the question of the intensity of review foregrounded in legal argument. The Court therefore sought to articulate the ‘standard of review’ and to apply it to the government's decisions. This way of framing the issue unfortunately sidelined the courts’ expository role in relation to intepreting the Habitats and SEA Directives, leaving key provisions under-analysed.     

Police officers who commit suicide by cop: a clinical study with analysis

Suicide by cop has become a familiar topic among members of law enforcement, mental health professionals, and the general public. This paper presents two cases where police officers chose to commit suicide by getting other police officers to kill them. The two police officers studied, by examination of closed case files, were found to be similar to civilians who committed suicide by cop on several demographic (gender, age, history of mental illness, and suicide attempts), and situational (stress factors, trigger) variables. The cases help us to understand possible motives and management for individuals who choose to end their life in this manner.
