The purpose of this study was to investigate the gender differences in the state of interpersonal needs and psychological health of male and female prison inmates who live in the same prison. The authors conducted in-person interviews with 118 male and 70 female inmates. The results show that women present a better interpersonal state and psychological health than do men. For both genders, the consequences of fulfilling or not fulfilling interpersonal needs-specifically, social loneliness and sexual satisfaction-are associated with psychological health. These findings suggest the importance of the state of prison inmates' interpersonal needs in promoting psychological health in the context of the prison, where these needs are generally difficult to be met. Making contacts possible between male and female inmates who are in the same prison might help them to better fulfill some of their interpersonal needs, especially those related to their sexual lives.  相似文献

The X chromosomal STR markers DXS10135 and DXS8378 in linkage group 1, DXS7132 and DXS10074 in linkage group 2, HPRTB and DXS10101 in linkage group 3, and DXS10134 and DXS7423 in linkage group 4 were studied in the Hungarian population. After genotyping unrelated men (219) and women (165), forensic efficiency parameters were calculated. Deviations from Hardy-Weinberg equilibrium could not be detected. There were several microvariant and rare alleles were sequenced: four in locus DXS10135 (alleles 17.1, 18.1, 20.1 and 26.1), one in locus DXS10074 (alleles 11), three in locus DXS10101 (alleles 26, 34.2 and 35) and five in locus DXS10134 (alleles 35.3, 37.2, 38.2, 39.2, 41).  相似文献

The aim of this study is to develop a scale to predict intimate partner femicide and severe violence. The sample consists of 1,081 batterer men who were reported to the police station. First, the most significant differences between the severe violence group (n = 269) and the less severe violence group (n = 812) in sociodemographic variables are determined. Both aggressors and victims of the severe violence group have a higher rate of immigration. Second, the proposed 20-item scale is derived from a larger 58-item scale, where only the most discriminative items between severe and nonsevere intimate partner violence are taken into account. Psychometric properties of reliability and validity are rather good. Cutoff scores have been proposed according to sensitivity and specificity. This easy-to-use tool appears to be suitable to the requirements of criminal justice professionals and is intended for use in safety planning. Implications of these results for further research are discussed.  相似文献

Most industrialized countries have seen part-time employment as a percentage of total employment increasing in the last decade. This paper presents the results of a comparative study of part-time employment in Spain and the Netherlands. The project comprises a legal comparative study of the effectiveness of the normative solutions provided by the Dutch and Spanish legal orders regarding the protection of part-time workers and the promotion of part-time employment, with special attention paid to the gender dimension of part-time work in both countries; and an analysis, based on data extracted from the European Community Household Panel (1995–2001), of the determinants of part-time employment in both countries and an examination of the extent to which part-time jobs are used as stepping-stones to full-time positions. We have found significant country differences regarding females’ decisions to take part-time jobs. We also have found that, in general, Dutch females are not less likely than their male counterparts to increase the number of hours they work. However, this applies only to those females who are part of a couple or have children younger than 12 years. In Spain, females are 2.6 times less likely than their male counterparts to switch from a part-time to a full-time job.  相似文献

Venous air embolism occurs when air enters the venous system. The main causes of venous air embolism include medical procedures, neck and head trauma, and injuries of the genitals. Self‐induced suicidal (and intentional) air embolism is extremely rare. The authors report a rare case of a suicidal air embolism committed using a self‐made tool composed of a plastic bottle and an infusion set, injecting nearly 2000 mL of air into the cubital vein. The toxicological analysis suggested that midazolam, together with air, was also injected into the circulation using the same bottle and infusion set.  相似文献

Abstract: Mitochondrial DNA (mtDNA) analysis has proved useful for forensic identification especially in cases where nuclear DNA is not available, such as with hair evidence. Heteroplasmy, the presence of more than one type of mtDNA in one individual, is a common situation often reported in the first and second mtDNA hypervariable regions (HV1/HV2), particularly in hair samples. However, there is no data about heteroplasmy frequency in the third mtDNA hypervariable region (HV3). To investigate possible heteroplasmy hotspots, HV3 from hair and blood samples of 100 individuals were sequenced and compared. No point heteroplasmy was observed, but length heteroplasmy was, both in C‐stretch and CA repeat. To observe which CA “alleles” were present in each tissue, PCR products were cloned and re‐sequenced. However, no variation among CA alleles was observed. Regarding forensic practice, we conclude that point heteroplasmy in HV3 is not as frequent as in the HV1/HV2.  相似文献

This article examines a case study of one industry in order to explore the factors influencing changing performance levels in the industries of post-socialist economies. It explores the influence on industrial performance of a number of once-only non-repetitive factors of market development that were typical of the transition period and compares them with longer term aspects of the market economy. The case that we discuss here is the development of the market for products of the Hungarian printing industry since the late 1980s. During the transition phase, privatisation, deregulation, the abolition of administrative distribution, and radical cuts in subsidies were all among the factors affecting this industry. Its supply chains also changed radically. However, these lost their importance after the transition had been completed and the long term processes of technical development and consumer behaviour became the main determinants of the behaviour of the printing companies.  相似文献

Despite recent changes in international relations and lapse of time since the fall of the USSR, the issue of Russian membership in NATO has been an ongoing fact. Hence, the principle scope of the paper is SWOT analysis of potential Russian membership in NATO from the perspective of the Russian Federation. Through the introduction and evaluation of advantages and disadvantages of such membership in the light of latest geopolitical events in Eurasia suggested by academic and professional circles in NATO countries and Russia, we proceed with identification of fundamental strengths, weaknesses, opportunities and threats that Russia might face. Taking into account such determining factors as the size of its territory, shifting geopolitical conditions in the world, modern understanding of security and a potentially frozen dispute in Ukraine, we come to the conclusion that benefits potentially brought by Russian membership in NATO could be sustained while drawbacks could be eliminated by incorporation of NATO to OSCE and a change in voting procedures of the Alliance.  相似文献
