The Potential of Internet Mobilization: An Experimental Study on the Effect of Internet and Face-to-Face Mobilization Efforts

In recent years, voluntary associations and political organizations have increasingly relied on Internet-based mobilization campaigns, replacing traditional forms of face-to-face recruitment and mobilization. Within the literature, one can observe an intensive debate about the possible consequences of this transition. Most importantly, the question is whether political mobilization through the Internet is just as effective as mobilization in a face-to-face setting. In this article, we report on a mobilization experiment using both traditional (face-to-face) and modern (Web site) incentives for mobilization. The experiment was conducted among undergraduate students in Belgium and Canada and included a test of medium-term mobilization effects. Results suggest that the Internet is successful in transferring knowledge and raising issue salience among respondents, but neither experimental manipulation led to significant behavioral changes. We do not find any indication that among this experimental sample Internet-based mobilization would be less effective than traditional face-to-face forms of mobilization.     

Who wins the most when everybody wins? Predicting candidate performance in an authoritarian election

ABSTRACT

What explains the variation in vote shares received by candidates in single-party authoritarian elections where everybody wins? The scholarly literature has often ignored institutional variations, treated all authoritarian elections as similar, and explained the variation of vote shares as a consequence of clientelism, coercion or electoral fraud. We employ a unique data set for Cuba’s 2013 National Assembly election to show an alternative answer: even in authoritarian regimes, institutional settings shape voters’ behaviour and candidates’ strategies. When the number of candidates on the ballot equals the number of parliamentary seats and yet voters can express some preference among multiple candidates, valence can become a predictor of candidate performance. Voters reward high-quality politicians, but not incumbents or Communist Party members, while candidates have no incentives to actively distinguish themselves and converge toward the general support of the single united slate.     

Posttraumatic Stress Disorder: Protective and Risk Factors in 18 Survivors of a Plane Crash

The aim of this study is to identify protective and risk factors related to the development of posttraumatic stress disorder (PTSD) on a sample of survivors from a single plane crash. Eighteen survivors were examined 6 months following the event. The subjects all underwent psychiatric interviews, Clinician‐Administered PTSD Scale structured interviews, personality and cognitive tests. Only 38.9% of them presented with all of the symptoms of PTSD; 22.2% showed no symptoms for PTSD; remaining survivors exhibited emotional/affective symptoms related to the event. In addition to the severity of the traumatic event itself, other risk factors identified were the loss of a relative, the manifestation of depressive symptoms, and the severity of physical injuries sustained. Low levels of hostility and high levels of self‐efficacy represented protective factors against developing PTSD.     

Demographic and clinical characteristics of 1092 consecutive police custody mental health referrals

The 43 police forces in England and Wales have made over 13 million arrests in the last decade. Yet, despite this high volume criminal justice system activity, and evidence of substantial health morbidity across the criminal justice pathway, mental health services in police custody have only been patchily developed, and the literature in this area is limited. Referrals (n = 1092) to a pilot mental health service operating across two police stations in a London borough were examined over an 18-month period in 2012/2013. The referred group had high levels of mental health and substance misuse problems (including acute mental illness, intoxication and withdrawal), self-harm, suicide risk and vulnerability (including intellectual disability), with some important gender differences. Although this work has limitations, the findings are broadly consistent with the small existing literature and they confirm the need for services that are sufficiently resourced to meet the presenting needs.     

Problematic Alcohol and Drug Use and the Risk of Partner Violence Victimization among Male and Female College Students

The current study expands previous research by examining the relationship between problematic alcohol and drug use and partner violence among a large sample of male and female college students and by partitioning out severe victimization for separate analysis. Data came from the International Dating Violence Study and included 4162 students from 19 colleges in the U.S. (69.1% women, 30.9% men). Victimization was measured using the revised Conflict Tactics Scale (CTS2). There was no significant main effect for alcohol use, but analysis of the interaction with gender found that problematic alcohol use was associated with victimization of men. Problematic drug use was associated with physical victimization, injury, severe physical victimization, severe psychological victimization, and severe injury for the overall sample in multivariate models. Interaction effects showed that elevated odds of severe injuries were associated high drug scores for women. Dating violence programs addressing dating violence on campuses are urged to include discussions on drug use and victimization of men.     

Multiplicative-innovation synergies: tests in technological acquisitions

Technological innovations enjoy synergies that vary in their speed and magnitude of impact, depending upon whether they are additive or multiplicative in nature. Additive-innovation synergies build incrementally on familiar technologies (as is reflected in the technologies built upon within their patents’ respective antecedents) and the duration of their effect is shorter-lived. Multiplicative-innovation synergies arise from combining greater proportions of diverse technologies and their effects have longer duration. The most-effective organizational-learning processes accompanying exposure to exotic technology streams via technological acquisition will occur if firms have properly invested in adaptive capacity to synthesize inventions using the unfamiliar knowledge. In the first tests of innovation synergies on firm performance, we find that technological novelty in patent content improves return on assets for firms that consistently invested in R&D. Using patent-content scores to characterize whether inventors have integrated greater proportions of exotic technological antecedents into their inventions (or not), we test the impact of innovation synergies on firms’ performance after technological acquisitions. Diversification posture (which could be an alternative explanation for performance differences) is negatively-correlated with innovation synergies in our results.     

Recovery and detection of urea nitrate in traces

Urea nitrate (uronium nitrate, UN) is a powerful improvised explosive, frequently used by terrorists in the Israeli arena. It was also used in the first World Trade Center bombing in New York in February 1993. It is difficult to identify UN in postexplosion debris, because in the presence of water it readily decomposes to its original components, urea and nitric acid. A method for the recovery and detection of urea nitrate in traces is described. The residues are extracted with hot acetone, and the extract chromatographed on chromosorb G-HP. The eluent is analyzed by liquid chromatography mass spectrometry using atmospheric pressure chemical ionization (APCI). By applying this technique, we were able to identify urea nitrate in actual exhibits. It was found that UN can be also formed during the analytical procedure, by certain combinations of urea, nitrate ions, and a source of protons and, hence, the presence of the characteristic adduct ion does not necessarily indicate an "authentic" urea nitrate. Several solutions are suggested to overcome this ambiguity.     

Why Emotions Matter: Expectancy Violation and Affective Response Mediate the Emotional Victim Effect

The mechanisms behind the ‘emotional victim effect’ (i.e., that the emotionality of a rape victim’s demeanor affects perceived credibility) are relatively unexplored. In this article, a previously neglected mechanism—observers’ affective response to the victim—is proposed as an alternative to the traditional expectancy-violation account. The emotional victim effect was replicated in an experiment with a sample of police trainees (N = 189), and cognitive load was found to increase the magnitude of the effect. Importantly, both compassionate affective response and expectancy violation actively mediated the emotional victim effect when the other mechanism was controlled for. These findings extend previous research on credibility judgments by introducing a ‘hot’ cognitive component in the judgment process. Theoretical and practical implications are discussed.     

Oil, Rape and State Crime in Nigeria

This case study seeks first to explore the culpability of the state of Nigeria in regards to recent allegations of rape and sexual torture by security forces and, secondly, to question why these rapes continue to occur despite Nigeria’s responsibility to address them. Though exact rates of violence are impossible to ascertain, reports by the media and various non-governmental organizations describe the widespread abuse of women, specifically at the hands of military officials. Evidence suggests that, by failing to respond appropriately to these acts of violence, the state of Nigeria is in direct violation of international law. Moreover, the decentralized nature of the Nigerian legal system creates an environment in which those Nigerian laws that do address rape and/or torture are rendered ineffective. This paper argues that what is happening in Nigeria does in fact constitute a state crime and, thus far, has not received appropriate attention from the International Criminal Court, to which Nigeria is a party, or the international community at large. As no action has yet been taken, we consider the factors that create an environment in which international and national punitive measures, as they are currently practiced, are ineffective.

“The big sleep: Elucidating the sequence of events in the first hours of death to determine the postmortem interval”

Recent developments on postmortem interval estimation (PMI) take an advantage of the autolysis process, pointing out to the analysis of the expression of apoptosis and autophagy genes towards this purpose. Oxidative stress plays a role in this signaling as a regulatory mechanism and/or as a consequence of cell death. Additionally, melatonin has been implicated on apoptosis and autophagy signaling, making melatonin a suitable target for PMI determination. The aim of this study was to investigate the early PMI through the analysis of the expression of autophagy genes as well as oxidative stress and melatonin receptor. Our results demonstrated a rapidly increased on the expression of autophagy genes according to the expected sequence of events, then a marked decrease in this expression, matched with the switch to the apoptosis signaling. These results revealed potential candidates to analyze the PMI in the first hours of death, helping to estimate the time-since-death.
