Electrophysiological and Behavioral Responses of Thanatophilus sinuatus Fabricius (Coleoptera: Silphidae) to Selected Cadaveric Volatile Organic Compounds

Soon after death, carcasses release volatile chemicals that attract carrion insects including Silphidae. Nevertheless, it is not known which chemical cues are involved in the attractiveness of the carcass. So far, little information is available on the chemical ecology of carrion beetles, particularly concerning the subfamily of Silphinae. The biological role of selected cadaveric volatile organic compounds including dimethyldisulfide (DMDS), butan‐1‐ol, n‐butanoic acid, indole, phenol, p‐cresol, putrescine, and cadaverine on the silphine species, Thanatophilus sinuatus Fabricius, was investigated using both electrophysiological and behavioral techniques. Among the tested cadaveric compounds, butan‐1‐ol and DMDS elicited the strongest electroantennography (EAG) from both T. sinuatus male and female antennae. In a two‐arm olfactometer, males and females were significantly attracted to DMDS for both tested doses, whereas only males were attracted to p‐cresol at 100 ng. Putrescine was repellent to males at the dose of 1 μg.     

Do drug courts reduce the use of incarceration?: A meta-analysis

Purpose

The objective of this research was to synthesize the empirical evidence on the effectiveness of adult drug courts to serve as an alternative to incarceration, and to investigate which features of drug courts predict successful diversion.

Methods

We performed a series of meta-analyses of different incarceration outcomes, and performed meta-regression analyses investigating which features of drug courts predict successful diversion.

Results

Drug courts significantly reduced the incidence of incarceration on the precipitating offense, corresponding to a reduction in confinement from 50% to 42% for jail and 38% for prison incarceration. However, drug courts did not significantly reduce the average amount of time offenders spent behind bars, suggesting that any benefits realized from a lower incarceration rate are offset by the long sentences imposed on participants when they fail the program. Meta-regression results indicated that certain drug courts features (i.e., program intensity, in-program sanctions, risk profile of participants) are related to incarceration outcomes.

Conclusions

The evidence concerning drug courts impact on incarceration is mixed. Drug courts eliminate the experience of incarceration for many drug-involved offenders, but they also do not appear to reduce the aggregate, near-term burden placed upon correctional resources. More research is required to confirm these findings.     

Job Stress and Job Satisfaction Among Jail Staff: Exploring Gendered Effects

Despite increased representation in correctional work settings, women still encounter obstacles in this male-dominated occupation—obstacles that have the potential to affect their levels of job stress and job satisfaction. Although gender-based differences in job stress and job satisfaction have been analyzed in several prison settings, much less work has been conducted in the often neglected correctional arena of jails. The current study fills this empirical void by examining jail staff at a large county correctional system in Orlando, Florida. Ordinary least squares regression analysis indicated that different facets of the work environment differentially affected the job stress and job satisfaction of 419 women and 493 men working in a large urban jail system. Specifically, role ambiguity, perceived dangerousness, coworker relations, input into decision making, and administrative support had larger effects on job stress for women compared to men. For job satisfaction, the only workplace variable to have a gendered effect was administrative support, which also had a greater effect for women than men. The findings reveal gender-related differences, especially in terms of job stress.     

Spaced cognitive interviewing: Facilitating therapeutic and forensic narration of traumatic memories

Abstract

The evolution of the cognitive interview (CI) is reviewed from the original package of memory-enhancing techniques through to the revised (or enhanced) CI, and the cognitive approach now taught to police officers in UK. Many officers are reluctant to apply CI, particularly to traumatised victims. The traumatising effects of crime are examined in terms of immediate response and the potential for an acute stress response and post-traumatic stress disorder, with subsequent re-experiencing of dissociated traumatic memories in the form of intrusive, unwanted imagery. Traumatic memories are described, particularly their accuracy, detail and persistence. The therapeutic potential of prolonged experience of distress while narrating the content of traumatic imagery is explained. An approach to maximising the disclosure of dissociated detail - spaced cognitive interviewing (SCI) - is described and case material presented illustrating its forensic and therapeutic application. The practice and practical implications of SCI are summarised.     

Why do French MPs Focus More on Constituency Work than on Parliamentary Work?

The relationship between French members of the National Assembly and citizens is paradoxical. On the one hand, the French political culture, constitution and history favour a very abstract conception of representation: MPs are supposed to act as trustees and collectively to embody the French Nation. On the other hand, they are deeply involved in their constituencies and express a great level of satisfaction being there. In order to understand how French MPs reconcile the national and local dimensions of their mandate, the data gathered through face-to-face interviews with MPs are described. Then a scale analysis is provided in order to sum up the local–national orientations of the MPs. Using this scale, it is possible to test the impact of several variables on the territorial focus of MPs: electoral incentives, political ambition, ideological factors and working conditions at the local and the national level.     

From Theory to Practice: Citizens’ Attitudes about Representation in France

French institutions, political culture and history have favoured a very abstract conception of representation: MPs are expected to embody collectively the French Nation, but little is known about citizens’ concrete views on representation. In this paper, data gathered through a citizen mass survey are used. To overcome the usual abstract considerations on representation, respondents were asked their opinion on an MP who would endorse amendments proposed by an interest group. In the questionnaire, two features were changed randomly: the MP's political leaning and the type of interest group. It is shown by means of an original experiment that the ‘general’ conception representation has disappeared from citizens’ attitudes: despite the enduring legitimacy of the general will approach in the public sphere, French citizens appear to promote a conception of representation close to the Madisonian views on pluralism involving a strong attachment to the logic of territorial electoral linkage.     

Connections Matter: How Interactive Peers Affect Students in Online College Courses

Peers affect individual's productivity in the workforce, in education, and in other team‐based tasks. Using large‐scale language data from an online college course, we measure the impacts of peer interactions on student learning outcomes and persistence. In our setting, students are quasi‐randomly assigned to peers, and as such, we are able to overcome selection biases stemming from endogenous peer grouping. We also mitigate reflection bias by utilizing rich student interaction data. We find that females and older students are more likely to engage in student interactions. Students are also more likely to interact with peers of the same gender and with peers from roughly the same geographic region. For students who are relatively less likely to be engaged in online discussion, exposure to more interactive peers increases their probabilities of passing the course, improves their grade in the course, and increases their likelihood of enrolling in the following academic term. This study demonstrates how the use of large‐scale, text‐based data can provide insights into students’ learning processes.     

Clientelism and Political Participation: Case Study of the Chinese <Emphasis Type="Italic">tongxianghui</Emphasis> in Macao SAR Elections

This paper investigates the close connections between Chinese tongxianghui (Chinese native-place association) and electoral politics in Macao SAR Legislative Assembly’s direct elections. The findings show that the Chinese tongxianghui in Macao SAR adopt clientelist politics based on cultural affinities during the electoral politics in gaining their client-voter supports for the direct elections in 2009 and 2013. The nature of clientelist relationships, such as interest maximizing exchange, reciprocity and iteration, building up long term and stable relationships, are different from the electoral campaigns in Western liberal democracies which are usually center on ideological lines and occasional exchanges which are arguably too random and too anonymous. In essence, this study argues that Chinese tongxianghui in Macao SAR, notably the Fujian Jinjiang tongxianghui and Guangdong Jiangmen tongxianghui, constitute powerful electoral engineering with affiliated interest groups and they have built up stable and long term clientelist relations with their clients, instead of waging electoral battles on ideological lines. Thus, this study contends that Macao’s direct elections represent a unique case study about participation of Chinese tongxianghui in electoral politics which can be characterized as a form of local-level, cumulative and low political-risk clientelism which could be more effective than ideological politics.
