Muscle contraction during electro-muscular incapacitation: A comparison between square-wave pulses and the TASER(®) X26 Electronic control device

Abstract: Electronic control devices (including the Advanced TASER^® X26 model produced by TASER International) incapacitate individuals by causing muscle contractions. To provide information relevant to development of future potential devices, effects of monophasic square waves with different parameters were compared with those of the X26 electronic control device, using two animal models (frogs and swine). Pulse power, electrical pulse charge, pulse duration, and pulse repetition frequency affected muscle contraction. There was no difference in the charge required, between the square waveform and the X26 waveform, to cause approximately the same muscle‐contraction response (in terms of the strength‐duration curve). Thus, on the basis of these initial studies, the detailed shape of a waveform may not be important in terms of generating electro‐muscular incapacitation. More detailed studies, however, may be required to thoroughly test all potential waveforms to be considered for future use in ECDs.     

Factors Affecting Individuals' Decisions to Use Community Mediation

This article presents research related to community mediation, specifically the factors affecting individuals' choices to accept or decline participation in the mediation process. Alongside a growing literature that emphasizes the significant benefits of mediation, this empirical study finds that individuals involved in personal relationships are more likely than individuals involved in business relationships to choose mediation. This data also finds a nonlinear and significant relationship between the length of time a conflict has been going on and participants' choice to use mediation. Finally, this article finds a significant and nonlinear relationship between differences in perception about the length of a conflict and whether a case is scheduled for mediation. Policy recommendations include suggestions to increase the use of mediation by responding directly to the cases that do not seem as likely to be mediated.     

Differentiating cause-of-death terminology for deaths coded as sudden infant death syndrome, accidental suffocation, and unknown cause: an investigation using US death certificates, 2003-2004

We compared written text on infant death certificates for deaths coded as sudden infant death syndrome (R95), unknown cause (R99), and accidental suffocation (W75). Using US mortality files supplemented with the death certifiers' written text for all infant deaths with International Classification of Diseases (ICD)-10 assigned codes R95, R99, and W75, we formed cause-of-death subcategories from common themes identified from the written text. Among all infant deaths in 2003-2004, the underlying cause of death was listed as R99 for 2128 deaths, R95 for 4408 deaths, and W75 for 931 deaths. Among the postneonatal deaths, the differences in subcategories varied between assigned ICD-10 codes: for R99-coded deaths, 45.8% were categorized as "Unknown" and 48.6% as "Pending"; for R95-coded deaths, 67.7% were categorized as "sudden infant death syndrome (SIDS)"; and for W75-coded deaths, 76.4% were categorized as "Suffocation." Examination of the written text on the death certificates demonstrates variability in the assigned ICD-10 codes which could have an important effect on the estimates of SIDS cases in the United States.     

The relationship of negative self-schemas and insecure partner attachment styles with anger experience and expression among male batterers

The purpose of the study was to explore how negative self-schemas and partner attachments were related to the experience and expression of anger (i.e., trait anger, inward and outward expression of anger) in a sample of male batterers (n = 40) who participated in court-mandated group services. They completed the Experience in Close Relationships (ECR), the Young Schema Questionnaire-2 (YSQ-2), the State-Trait Anger Expression Inventory-2 (STAXI-2), and a demographic sheet. Male batterers who experienced pervasive anger (i.e., trait anger) tended to experience negative self-schemas associated with the Impaired Limits domain (respecting the rights of others, insufficient self-control, entitlement). Male batterers who tended to suppress their anger tended to feel avoidantly attached to their romantic partner and endorsed negative self-schemas associated with the Disconnection and Rejection domain (abandonment, emotional deprivation, defectiveness/shame). Implications for clinical practice with male offenders and future research are discussed.     

Gender inequality, violence against women, and fear: a cross-national test of the feminist theory of violence against women

This article presents a cross-national test of the feminist theory of violence against women. Combining data from the International Crime Victims Survey (ICVS) with United Nations statistics, the findings support the theory. Specifically, the results indicate that the educational and occupational status of women in a country is related to the prevalence of sexual violence against women. In countries where the status of women is low, prevalence of sexual violence against women tends to be higher. In turn, sexual violence is related to higher levels of fear among women relative to men. In comparison, in countries where the status of women is high, sexual violence against women is lower. The findings of this study add confirmation to the argument that we need to look beyond individual level variables to understand and develop strategies for reducing violence against and fear among women.
