The regular article tracking developments at the national level in key European countries in the area of IT and communications – co-ordinated by Herbert Smith LLP and contributed to by firms across Europe. This column provides a concise alerting service of important national developments in key European countries. Part of its purpose is to compliment the Journal’s feature articles and briefing notes by keeping readers abreast of what is currently happening “on the ground” at a national level in implementing EU level legislation and international conventions and treaties. Where an item of European National News is of particular significance, CLSR may also cover it in more detail in the current or a subsequent edition. 相似文献

Much of the existing research on the prevalence and consequences of peer victimization focuses on “bullying” at school, often
omitting from consideration non-bullying types of peer victimization as well as events that occur outside of school. The purpose
of this study was to examine past-year exposure to peer-perpetrated victimization, occurring both within and outside of school
contexts, among school-aged children in the United States. The study is based on a representative sample of 2,999 youth ages
6–17 (50% female; 45% non-white) from the 2008 National Survey of Children’s Exposure to Violence (NatSCEV). Findings revealed
age, gender, race, and family structure variations in many forms of peer victimization and demonstrated significant independent
and cumulative effects of six different types of peer victimization (physical assault, physical intimidation, emotional victimization,
sexual victimization, property crime, and internet harassment) on trauma symptoms. Findings also showed that, although victimization
at school is substantial, a considerable proportion of peer victimizations occur away from school contexts. The findings highlight
the importance of comprehensive measurement of multiple forms of peer victimization that occur both at school and elsewhere,
rather than focusing exclusively on traditional measures of school-focused bullying. 相似文献

Identification of an ignitable liquid in fire debris evidence can be complicated due to evaporation of the liquid, matrix interferences, and thermal degradation of both the liquid and the matrix. In this research, liquids extracted from simulated fire debris were compared to the original liquid using multivariate statistical procedures. Neat and evaporated gasoline and kerosene standards were spiked onto nylon carpet, which was subsequently burned. The ignitable liquid residues were extracted using a passive headspace procedure and analyzed by gas chromatography-mass spectrometry. Pearson product moment correlation coefficients, hierarchical cluster analysis, and principal components analysis were used to compare the liquids extracted from the carpet to the corresponding neat liquid. For each procedure, association of the extracts according to liquid type was possible, albeit not necessarily to the specific evaporation level. Of the three procedures investigated, principal components analysis offered the most promise since contributions from matrix interferences were essentially eliminated. 相似文献

Diverse questions might be contemplated once we consider the gender implications and impacts of Aboriginal exemption policies. The article traces such questions in relation to a series of distinct episodes in the history of exemption. The first of these focuses on postwar New South Wales, where marital status was core to the application process from the point of its introduction, and the system built upon older policies of ‘training’ Aboriginal girls as servants. The second moment, moving back in time, discusses a petition for collective exemption for a group of women domestic workers in Broome, Western Australia, that was presented to a government enquiry in 1934. The third concerns the quest for release from government controls by several domestic workers brought to Adelaide in South Australia, from the Northern Territory, in the late 1920s. Finally, the article reflects upon the efforts of young women placed in service in early-twentieth-century Brisbane, Queensland, to secure exemptions, and the responses of the authorities. While exemption policies may have been designed to impose Anglo-Australian gender norms of female dependence, Aboriginal women who worked in service consistently subverted these aims, by using the discourses of domesticity to challenge and resist the authorities' power. 相似文献

Energy poverty is a major challenge in the developing world, with an estimated 1.2 billion people lacking household electricity. Although energy poverty affects both men and women, the burden of household energy supply disproportionately affects women in low-income countries in the developing world. This article examines the impact of a women-oriented solar lighting social enterprise, Solar Sister, in Tanzania for both solar entrepreneurs and customers, demonstrating that solar lanterns positively impact household savings, health, education and women’s economic productivity and empowerment. Our study argues that Solar Sister’s approach is successful because of its explicit gender lens. Providing energy access to women translates to a pro-woman, pro-child, and pro-family development intervention. 相似文献

The main theses of this article, completed on the eve of the NATO bombing campaign, remain relevant. With half of Europe's Muslim Albanians living outside Albania proper in Slavic and Greek Orthodox countries, the resultant risk of a broader Balkan conflict remains. Indeed, the sense of grievance of both Serbs and Albanians has been intensified by ethnic cleansing, bombing, dispossession, and polarization. Those like Kosovar shadow President Rugova, who were committed to multi‐ethnic compromise, have been pushed aside by the KLA. Increasingly, the long‐term solution in Kosovo appears to be one of independence from both Serbia and Albania with the rights of Serbs preserved by partition policed by NATO/UN forces. 相似文献

This article reports on a study that aimed to understand the effects for poverty reduction of the link between logistic services and cost of the watermelon value chain in Rufiji and Mkuranga districts in Tanzania. Structured questionnaires and FGDs were used to collect data from 251 respondents. Findings revealed that transport cost, storage cost, purchase cost, and logistics service have strong significant effect on the watermelon value chain cost. Based on the findings, the study recommended the use of affordable methods of storage, opening agro-input shops in villages, and the development of a favourable environment for watermelon businesses, to help reduce chain cost. 相似文献

The presence of diatom algae in bone marrow has been used as forensic evidence of drowning for several decades; however, these studies are based on known or suspected recent drowning events. This study addresses the potential for diatoms to enter the bone marrow of skeletal remains, that is, de-fleshed long bones post-mortem. In laboratory and field experiments, bones were either inflicted with two access points by a cut and acid pitting or left intact. The bones were submerged in water for at least 1 week and up to 3 months. Samples of the bone surface and marrow were inspected for diatoms. The analysis considered the time required for diatoms to enter marrow and whether genus characteristics like size or mobility affect entry. The presence of an access point influenced diatom entry in that bones without an introduced access point had zero to one diatom present in the marrow, whereas a bone with an access point had >150 diatoms present in the marrow. The results of both laboratory and field phases suggest that diatoms will reliably colonize bone in as quickly as 1 week, establishing and maintaining communities for at least 3 months. However, the bone surface assemblages differ from the source community. Bone marrow displayed even more restrictive access to diatom colonization, resulting in communities dominated by small raphid diatoms. Based on these findings, we suggest some caveats on the use of diatoms as trace evidence in forensic science with recommendations for future avenues of research. 相似文献
