Observing Erotic Videos With Heterosexual Content Induces Different Cerebral Responses in Homosexual and Heterosexual Men

ABSTRACT

To determine the cerebral functionality associated with the perception and processing of erotic stimuli in men with different sexual orientation, this work evaluated the electroencephalographic activity (EEG) from several cortical areas, as well as subjective arousal in homosexual and heterosexual men during observation of an erotic film with heterosexual content. The heterosexual men rated the erotic video with higher general and sexual arousal than the homosexual participants. During observation of the neutral and erotic videos, both groups showed a decreased amplitude of the alpha band in prefrontal and parietal cortices, indicating increased attention. When watching the erotic video, the homosexual men showed an increased amplitude of the theta and fast bands only in the prefrontal cortex, which could be related to the cognitive processing of the erotic stimulus. These EEG results should broaden our knowledge of the cortical mechanisms related to the different perception and processing of erotic stimuli in men with different sexual orientations.     

Cessation of breastfeeding in association with oxytocin administration and type of birth. A prospective cohort study

Background

Some studies have suggested an association between synthetic oxytocin administration and type of birth with the initiation and consolidation of breastfeeding.

Inter‐organizational Cooperation and Environmental Change: Moderating Effects between Flexibility and Innovation Performance

The paper investigates the moderator effect of inter‐organizational cooperation in the relationship between workplace flexibility and innovation performance. This research question is important because innovation is dependent on the strategic integration of technological knowledge, requiring organizations to acquire new capabilities rapidly or to ensure the presence of knowledge that may be beyond existing internal capabilities. Inter‐organizational cooperation constitutes a relevant mechanism for a firm to increase its knowledge base concerning new products and processes. High‐cooperation firms may have more opportunities to take advantage of flexibility for innovation performance because it facilitates the access and dispersion of knowledge within the firm. We test the research hypotheses in a sample of manufacturing and service firms. The results contribute to the literature on flexibility and innovation because they demonstrate that inter‐organizational cooperation moderates the relationship between flexibility and innovation performance. We discuss the implications of these results for future research and managerial practice.     

Xinjiang under China: reflections on the multiple dimensions of the 2009 Urumqi uprising

In 2009, a demonstration in Urumqi deteriorated into one of the bloodiest riots in contemporary Chinese history. Some scholars and media groups have responded to the event by focusing public attention on the bottom-up, ethnic, and social aspects of Xinjiang’s conflict phenomenon. This article raises questions and concerns about framing the 2009 event from an ethnic and social standpoint. The authors combine conflict studies with a longue durée historical analysis to argue that multiple dimensions and the intersections of these dimensions constitute the 2009 Urumqi uprising. Present conflict is placed against a backdrop of unequal Chinese state policies with Xinjiang. The authors then forward a Uyghur perspective underpinned by peace and conflict studies concepts. The conclusion recommends conflict prevention strategies by urging the Government of the People’s Republic of China to take ownership of the consequences of its policies and the broken contracts with Uyghur minorities in Xinjiang.     

A multi-criteria approach for managing inter-enterprise collaborative relationships

Collaboration amongst enterprises is a common strategy used to increase competitiveness. Thus, enterprises that are collaborating need to define and use performance measurement/management frameworks composed of performance elements (objectives, performance indicators, etc.) that facilitate the management of their activity, as well as monitor their strategy and processes. There are many factors, e.g. trust, interoperability of Information Systems, etc. that need to be managed properly in order to support collaborative success. However, such factors and performance are not usually managed together. Furthermore, these factors and performance elements are interrelated but these influences are commonly overlooked. This paper aims to present an approach based on the Analytic Network Process (ANP) to manage collaborative relationships under an integrated approach by considering not only the inter-enterprise performance elements, but also the factors that influence collaboration. The approach is then applied to a collaborative enterprise network belonging to the renewable energy sector. With this innovative approach, enterprises will obtain significant information for the decision-making process, regarding which are the factors and performance elements that have the greatest impact on their competitiveness, and therefore should be prioritized.     

Victim Evaluations of Face-to-Face Restorative Justice Conferences: A Quasi-Experimental Analysis

One major goal of face-to-face restorative justice (RJ) is to help heal the psychological harm suffered by crime victims ( Braithwaite, 2002 ). Substantial evidence from randomized controlled trials (RCTs) has shown that this can be accomplished ( Strang, 2002 ) and more trials are underway ( Sherman & Strang, 2004 ). These outcomes are even more clearly, if less rigorously, demonstrated through retrospective interviews of victims about their feelings before and after RJ took place. We review the responses of victims ( N = 210) who participated in trials in Canberra (Australia) and in London, Thames Valley, and Northumbria (UK). Despite substantial variations in offense types, social contexts, nation and race, before-after changes revealed by qualitative and quantitative data are all in the same beneficial direction.     

Stability and Change in the Experience of Partner Violence Among Low‐Income Women*

Objective. In this analysis we identify factors associated with the dynamics of partner violence among low‐income women. Methods. Using two waves of the Welfare, Children and Families Study (1999–2001), we examine the multivariate predictors of ever having experienced abuse, as well as factors associated with the initiation, resumption, and discontinuation of violence between the two interviews. Results. Over half the women who reported violence at Wave 1 reported no violence at Wave 2. These women were older, had experienced less severe violence, and reported less financial strain than women for whom violence continued or began. For 11 percent of the sample, violence began or resumed by the second interview. These women were younger, less educated, had weaker social networks, and were less likely to be Hispanic than those who never experienced violence. Conclusions. Partner abuse appears to be highly dynamic and a fuller understanding of the phenomenon requires a longitudinal focus.     

Maternal Punitive Reactions to Children's Negative Emotions and Young Adult Trait Anger: Effect of Gender and Emotional Closeness

The current study tested whether young adult's recollected reports of their mother's punitive reactions to their negative emotions in childhood predicted anger expression in young adulthood and whether emotional closeness weakens this association. Further, a three-way interaction was tested to examine whether emotional closeness is a stronger protective factor for young women than for young men. Results revealed a significant three-way interaction (gender × emotional closeness × maternal punitive reactions). For young men, maternal punitive reactions to negative emotions were directly associated with increased anger expressions. Maternal punitive reactions to young women's negative emotions in childhood were associated with increased anger in adulthood only when they reported low maternal emotional closeness. Findings suggest that maternal emotional closeness may serve as a buffer against the negative effects of maternal punitive reactions for women's anger expression in young adulthood.
