Profile of Men Who Are Victims of Physical Violence by an Intimate Partner

The objective of this study was to characterize the profile of men who are victims of interpersonal physical violence (IPV) by an intimate partner. This study is a retrospective analysis of suspected cases of male victims of IPV by an intimate partner, aged 18 years or older, treated at a Forensic Medicine and Dentistry Center in Brazil. Sociodemographic variables of the victims, the types of violence and the patterns of injuries were evaluated. Over this period, 1520 suspected victims of IPV by an intimate partner were examined; 14.6 % (n = 222) of them were men. Based on Multiple Correspondence Analysis (MCA) two dimensions were formed: the first dimension (internal reliability = 0613) was primarily formed by the relationship between aggressor and victim, the marital status and the type of IPV, and the second dimension (reliability = 0509) by the day of week, the period of day and the marital status.     

Adaptation of the Narcissistic Personality Inventory among a Portuguese sample of incarcerated juvenile offenders

The aim of the present study was to assess the psychometric properties of the Narcissistic Personality Inventory (NPI) and two of its short forms (NPI-16 and NPI-13) among a Portuguese sample of male incarcerated juvenile offenders (N?=?221). Of these, only the NPI-13 short version demonstrated a good fit in terms of its factor structure. The NPI-13 also showed promising psychometric properties in terms of its internal consistency, convergent validity, discriminant validity, and criterion-related validity. Statistically significant associations were found with age of crime onset, crime seriousness, conduct disorder symptoms, alcohol abuse, and cannabis use. These findings justify the use of the NPI-13, especially its Entitlement/Exploitativeness dimension, among incarcerated male youths.     

中国政治的可持续发展在于实现党与公民社会的良性互动

政治文明建设应从国家与社会的辩证关系出发,以一种合作的视野来认识国家与社会的关系,强调相互促进良性互动。公民社会在推动民主和发展这两大潮流中发挥着重要作用,构建一个健康而有序的公民社会已成为发展社会主义政治文明的必然趋势。党融入公民社会,实现治理与善治,反映了中国共产党在党和社会关系问题上的科学逻辑。     

Diverse morphological lesions and serious arrhythmias with hemodynamic insults occur in the early myocardial contusion due to blunt impact in dogs

To investigate the morphology and hemodynamics of the early myocardial contusion, an animal model of cardiac contusion was established by impact to the precordial region at sternum at velocity of 10.0m/s with a mechanical elastic-cord propelled impactor in 19 dogs. The electrocardiogram and both the left and right intra-ventricular pressures were recorded continuously throughout the experiment. Histological and immunohistochemical examinations of myoglobin, creatine kinase-MB and fibrinogen were conducted. At the moment of impact, abrupt over-pressures within the left and right ventricles occurred with concomitant serious arrhythmias followed by variety of cardiac conduction disorders and depressed left and right ventricular systolic pressures during the observation times. Histologically, lesions of myocardial contusions were identified at subepicardial, myocardial or subendocardial layer as interstitial hemorrhage, disruption or coagulative necrosis as well as contraction band necrosis of the muscle fibers, which might be categorized into the hemorrhagic, necrotized and mixed forms. The three forms of lesions were found to exist independently, or co-existed in a heart. However, severity of the lesions varied greatly with different parts even within a heart. Intravascular thromboses were occasionally discovered post-impact. Immunohistochemically, loss of myoglobin and creatine kinase-MB from cardiac cells, and accumulation of fibrinogen at the cell membranes were detected 5min post-impact. The intracellular accumulation of fibrinogen increased with extension of post-impact intervals. Our results indicate that diverse morphological lesions concomitant with hemodynamic compromise and serious, even fatal arrhythmias occur in the early myocardial contusion, and intravascular thromboses are occasionally produced, suggesting that traumatic myocardial ischemic lesion may be induced due to blunt impact to the precordial region.

Between Renewal and Stability: Party System Change from a Multi-Level Perspective in Brazil (1998–2018)

The growth of the far right and election results in Brazil are often associated with national or large-scale events. The multi-level features of these developments, namely party competition at the sub-national level, are overlooked in the literature. This article argues that changes in the Brazilian national party system – those observed from Bolsonaro's election, mainly – are rooted in sub-national political dynamics. Through a comparative and longitudinal analysis of multi-level executive and legislative elections, we find that, although there are distinct patterns of competition between the national-sub-national and within-country levels, this difference is not evident in volatility.
