Relationship between mousekilling and conspecific aggression in the male rat

In order to investigate the relationships between mousekilling and conspecific aggression, behavioral variables of killer and nonkiller rats were compared in a “resident-intruder” paradigm, in resident as well as in intruder animals. The occurrence of offensive items (offensive sideways, attack) was significantly higher in killer rats when they were residents; their corresponding opponents displayed more defensive behaviors. No significant difference in aggressive behaviors was noted when the comparison was done in the intruders. These results and those of previous studies suggest that there is a correlation between mousekilling and intraspecific offensive behaviors. Some similarities in the situations where both behaviors are elicited–eg, introduction of an unfamiliar intruder into a familiar environment–may contribute to the existence of such a correlation and the possibility of common mechanisms underlying both behaviors is discussed.     

On the origin of normative argumentation theory: The paradoxical case of the Rhetoric to Alexander

The Rhetoric to Alexander (second half of the fourth century B.C.) is among the oldest contributions to the study of argumentation. From antiquity on, this treatise, which abounds in opportunistic advice, has come under heavy criticism on normative grounds. And yet, as I shall maintain here, it clearly takes into account the requirements of rational argumentation which are still in use today. Moreover, it contains the seeds of a whole series of doctrines found in modern normative argumentation theory. There are reasonable grounds for maintaining that some of these modern doctrines stem indirectly from the tradition to which the Rhetoric to Alexander belongs.     

The Oldest Typology of Argumentation Schemes

The Rhetoric to Alexander (about 340 B.C.) contains a list of proofs (pisteis) and other types of argumentation which may be seen as the oldest surviving typology of argumentation schemes (avant la lettre). In the present article this typology is derived and compared with modern proposals. The conclusion is that the oldest typology is surprisingly similar to the most recent classifications.     

Les enjeux de l’entreprenariat immigré

This article reviews the major findings of the scholarship on immigrant economies and critically analyses the use of the notion of ethnicity therein. It first presents the context and the opportunities of entrepreneurs (micro- and macro-context, support policies, transnationalism, informal economies), before describing the resources mobilized by businesspeople. These include, in particular, networks and ethnic/social capital, whose relationships with factors such as class, gender, culture, and social mobility are investigated. The article concludes by questioning the very notion of ethnic economies, arguing that it may lead to an over-ethnicisation of business practices within immigrant groups.     

Pilot Mindfulness Intervention for Children Born with Esophageal Atresia and Their Parents

A pilot mindfulness home intervention was conducted for 6 weeks among 8–12-year-old children born with esophageal atresia and their parents. Participants were randomly assigned to a waiting list control (WLC) group (n?=?8) and an experimental group (n?=?12). When all participants had completed the mindfulness-based program, data were pooled and treated for the entire sample (n?=?19). Self-assessment measures included the Mindful Attention Awareness Scale for Adolescents (MAAS-A), the Child and Adolescent Mindfulness Measure (CAMM), the modified Spielberger State-Trait Anxiety Inventory—Child (STAI-C), the Children’s Depression Inventory (CDI), and the Cognitive Emotion Regulation Questionnaire Kids version (CERQ-k). Parental assessment measures included the modified STAI-C. The results underlined the program’s feasibility and acceptability. Clinical effects of the mindfulness-based program were observed. Self-assessed data for children who had practiced mindfulness compared to the WLC group showed increased mindfulness and decreased depression. Reduced anxiety was found in all groups. Positive affect tended to improve from pre-test to post-test in children who had practiced mindfulness compared to the WLC group. Parental assessments showed significant improvement in positive affect and decreases in anxiety and negative affect in the intervention group compared to the WLC group. Cognitive emotion regulation strategies were also affected by the mindfulness-based program. Rumination scores significantly decreased from pre-test to post-test in the intervention group. This preliminary study suggests that regular mindfulness practice presents a promising approach to reducing the burden of this neonatal malformation.     

Improving accuracy in detecting acoustic onsets

In current cognitive psychology, naming latencies are commonly measured by electronic voice keys that detect when sound exceeds a certain amplitude threshold. However, recent research (e.g., K. Rastle & M. H. Davis, 2002) has shown that these devices are particularly inaccurate in precisely detecting acoustic onsets. In this article, the authors discuss the various problems and solutions that have been put forward with respect to this issue and show that classical voice keys may trigger several tens of milliseconds later than acoustic onset. The authors argue that a solution to this problem may come from voice keys that use a combination of analogue and digital noise (nonspeech sound) detection. It is shown that the acoustic onsets detected by such a device are only a few milliseconds delayed and correlate highly (up to .99) with reaction time values obtained by visual waveform inspection.     

Subjective valuation and asymmetrical motivational systems: implications of scope insensitivity for decision making

Studies using the Iowa Gambling Task have revealed individual differences in performance on the task. In this study, we tested the hypothesis that approach and avoidance motivations influence decision making through the process of subjective valuation. We examined the implications of a high sensitivity to gains or losses from two perspectives which we labeled scalar multiplication and valuation by feeling. Using two versions of the Iowa Gambling Task, we find evidence supporting the view that asymmetry in the systems regulating approach and avoidance leads to systematic biases that translate to differences in performance. Specifically, we find that high sensitivity in the Behavioral Activation System (BAS) translates to valuation by feeling and insensitivity to scope in the domain of gains, while high sensitivity in the Behavioral Inhibition System (BIS) translates to valuation by feeling and insensitivity to scope in the domain of losses. The basis for these findings is discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

Impact de la Loi no 2019-222 du 23 mars 2019 de programmation 2018–2022 et de réforme pour la justice sur l’office du médecin légiste

The new provisions of the article 60 of the French Code of Criminal Procedure now authorize the medical examiners to seal the samples taken during an autopsy or a medical examination. The result will be a new organization of the work of forensic doctors that the 2010s reform did not integrate. In addition, the presence of judicial police officers during the autopsies will probably have to be rethought. Moreover, the article 163 of the same code has not been amended, giving more competence to qualified persons than to experts appointed by an investigating judge.
