The article presents the final part of an Icelandic research project on parents and children of divorce, focusing on grown-up children’s experiences of equal time-sharing arrangements, ETSA, after their parents’ divorce. It consists of a quantitative analysis of firstly a nationally representative sample mapping the frequency and experience of 18–59 years old individuals of ETSA after parents’ divorce, and secondly a qualitative analysis of 16 long interviews with 16 children of divorce reflecting on their experiences. Both analyses indicate different experiences of this type of arrangement. The reality of the arrangement in practice is that parents chose the arrangement on the basis of their own preferences rather than a court imposing it or because the generally accepted core conditions for a positive outcome for children were in place. These negative experiences of ETSA are discussed in further detail and the need for law reform and service improvement is considered.  相似文献

Ignitable liquids such as fuels, alcohols and thinners can be used in criminal activities, for instance arsons. Forensic experts require to know their chemical compositions, as well as to understand how different modification effects could impact them, in order to detect, classify and identify them properly in fire debris. The acid alteration/acidification of ignitable liquids is a modification effect that sharply alters the chemical composition, for example, of gasoline and diesel fuel, interfering in the forensic analysis and result interpretation. However, to date there is little information about the consequences of this effect over other accelerants of interests. In this research paper, the alteration by sulfuric acid of several commercial thinners and other accelerants of potential use in arsons is studied in-depth. For that purpose, spectral (by ATR-FTIR) and chromatographic (by GC–MS) data were obtained from neat and acidified samples. Then, the spectral and chromatographic modifications of each studied ignitable liquid were discussed, proposing several chemical mechanisms that explain the new by-products produced and the gradual disappearance of the initial compounds. Hydrolysis, Fischer esterification and alkylation reactions are involved in the modification of esters, alcohols, ketones and aromatic compounds of the studied ignitable liquids. This information could be crucial for correctly identifying these accelerants. Additionally, an exploratory analysis revealed that some of the most altered ignitable liquid samples might be very similar with each other, which could have impact on casework.  相似文献

We have analysed the information in 342 police reports of stranger sexual offences recorded in 2010. We have carried out a multiple correspondence analysis and a cluster analysis using modus operandi variables to identify differential profiles in these types of sexual offences. We have come up with three profiles of stranger sexual offences, which concur in the two techniques used. By analysing the personal variables of the offenders with such profiles, we have found differences in terms of the offender’s country of origin and age. We will discuss the consequences of these results on the police investigation of stranger sexual offences.  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

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

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
