Family violence (FV) harms communities worldwide so FV prevention strategies and effective responses are urgently needed. This article reports on FV apparent in a study which explored the experiences of people with both ABI and justice system encounters in Victoria, Australia. One hundred interviews and one focus group consulted people with ABI, their families and carers, and various stakeholder groups in the Victorian justice system in Australia. Qualitative content analysis determined dominant themes and sub-themes and the less common themes. Inductive interpretive content analysis identified themes commonly found in previous published research and themes that appeared unique to, or unanticipated in, our data, such as the FV theme upon which this article focuses. Our findings reveal that FV has adversely affected many people with ABI who came into contact with Victoria’s justice system. Further, as ABI and FV often co-occur with substance abuse, mental health problems, socio-economic and many other significant disadvantages, for some FV perpetrators with an ABI, their ABI symptoms and characteristic co-morbidities may be a mitigating factor in their offending. The connection between ABI and family violence emerged as a troubling research theme. Indeed, the impact of FV on too many of our participants with an ABI compels us to call for further related research and secondary prevention programs targeted at FV victims, and offenders, living with ABI. An intersectional understanding of family violence and TBI/ABI in social ecological contexts is required to better understand brain injury at both individual and population levels.

The European Commission Proposal for a Directive on the Patentability of Computer-implemented Inventions is an important step towards harmonising and clarifying the patent protection available for such inventions in European Member States. This paper discusses the proposed Directive, its potential impact and some initial reactions from those in the software industry. It outlines the background to the Proposal, discussing briefly the exclusion of computer programs 'as such' from patent protection under the European Patent Convention (EPC). The paper observes that, in its current form, the proposed Directive will narrow the protection currently available to patentees and that some thought should be given to transitional provisions. It concludes that, whatever balance is struck as the Directive progresses to adoption, the Directive will have the benefit of providing a mechanism for aligning the approach of European Member States to patenting computer-implemented inventions. 'Educational initiatives' may, however, be required if European companies, in particular Small and Mediumsized Enterprises (SMEs), are, as intended by the Commission, to view the harmonization and greater transparency provided by the proposed Directive as an incentive to use patents to exploit their computer-implemented inventions.  相似文献

In his protracted dispute with Jan Adam over the early benefits of the Polish ‘shock therapy’ approach to economic reform, a key, and still intact, component of Jeffrey Sachs' case has been a relatively favourable 1991 opinion poll about Poles' perceptions of the benefits of economic reform. This reported that a substantial majority of Poles felt their standard of living had improved as a result of the first two years of economic reform. This was an apparently powerful argument in favour of Poland's particular shock therapy approach to economic reform, as residents of other East European countries, some subject to more gradualist reforms, responded much less positively to the identical question put as part of the same research programme. However, the cited result should be seen as posing a mystery that is at odds with other monthly polls in Poland and seems incompatible with the results of the 1991 Polish Parliamentary elections, which showed a return of support to post-communist parties. A deeper analysis of opinion polls which follows solves the mystery, when it is shown how the cited result was in error and was published in a form diametrically opposite to the true result.  相似文献

Allele frequencies for 17 STRs, together with some parameters of forensic interest, were estimated in a sample of 835 unrelated individuals born in Tuscany, an Italian region. These data were compared with Italian, Chinese, Kosovo Albanian, Romanian and Tunisian populations, strongly represented in this area. No significant differences in single loci were detected, except for Chinese in comparison with all the other populations.  相似文献

Feminist economics draws increasing attention from professional mainstream economists. In this paper, we discuss methodological issues, some theoretical developments – notably on the household – and issues of economic policy. We point to parallels between feminist economics and institutional economics, and argue that these relations might be strengthened to the benefit of both.  相似文献

Elections have emerged as a leading area for the application of biometric technology in developing countries, despite its high costs and uncertainty over its effectiveness. Why then do countries pursue such programs, often with the support of donors? The paper considers the costs and benefits of technology, where the latter involves its potential to reduce the probability of seriously disputed elections that escalate into violence. Based on the limited data available, it finds that a reduction in the probability of postelection violence by only a few percentage points could offset the cost of the technology. However, this is far from assured; we argue that biometric technology can only contribute to less disputed and less violent elections in particular settings, those where democracy is not yet well institutionalized but where political parties value the legitimacy conferred by elections that are sufficiently credible for their results to be accepted. One priority is therefore to screen potential cases carefully, before investing in costly programs that have a low probability of success. Another step toward using technology more effectively to underpin sustainable elections would be to build on voter registration drives to strengthen permanent identification assets such as civil registration and national ID programs that can serve as the basis for the voter roll.  相似文献

Technology Transfer Centres (TTCs) have been analyzed in the last few years by focusing on the relationship between a TTC, provider of knowledge-intensive services, and a firm client-receiver. Less attention has been devoted to a more complex relationship which involves in the dyadic provider-receiver tie a third relevant body, University. We provide both a theoretical and an empirical contribution by studying whether TTCs can bond the academic and industrial system and we define the activities that make-up this role such as: scanning and selection of R&D opportunities, bridge building, semantic translation of domain specific knowledge, co-production of new knowledge. The boundary spanning role of TTCs is discussed drawing on different and complementary theoretical perspectives. Moreover, we test research hypotheses on the antecedents of boundary spanning activity from a knowledge-based perspective. We argue that TTC boundary spanners need to leverage on both technical skills and networking competences. Empirical investigation has been carried out with a survey of the TTC population of North East Italy. The research findings highlight the task coordination activities implied by a boundary spanning role in joint R&D projects and show that the endowment of human capital at individual level and a qualified social capital at individual and organizational level are the main determinants.  相似文献
