It is a requirement that forensic DNA profiling evidence be accompanied by an estimation of its weight, in order that the court can assign an appropriate probative value to the evidence during legal proceedings. There are various models by which this estimation can be made, but each relies on approximations of the allele frequencies in the relevant population. It is also important to assess relevant population genetic features of the available data. This report provides allele frequencies and estimates of common population genetic parameters for the major sub-populations of the Northern Territory of Australia genotyped at 15 autosomal short tandem repeat (STR) loci.  相似文献

Using the Mahoney–Thelen causal model one would expect “layering” to be the dominant kind of institutional change affecting Swiss banking secrecy. Our research into governance in Swiss banking shows that it does not fit this theoretical model. Applying deviant case analysis we have refined our understanding of institutional change. We argue that the removal of rules and the momentum of pressure should be acknowledged when explaining variations of institutional change and we suggest that the processes of shrinkage should not be ignored.  相似文献

Important gaps exist in our understanding of aggressive behavior and the extent to which aggression involves one or more types of victims. This information is critical for determining the utility of integrated approaches for violence prevention versus continuation of independent efforts for reducing community violence, partner violence, and child maltreatment. To better understand the overlap in aggressive behaviors within the general population, the authors examine the co-occurrence of self-reports of physically striking strangers, acquaintances, intimate partners, and children among a nationally representative sample of 3,024 U.S. adults. The findings from this cross-sectional random digit dial telephone survey show that more than a third of the population reports engaging in at least one form of aggression and that, of these, a third had perpetrated violence against more than one type of victim. The percent of respondents who reported perpetrating violence against more than one type of victim range from 13% (percent of those striking a friend or acquaintance who also struck a child) to 34% (percent of those striking a friend or acquaintance who also struck a stranger). Furthermore, engaging in one type of aggression substantially increases the odds of engaging in another from 1.5 to 4 times. The findings suggest potential value in pursuing both integrated and independent approaches in research and prevention.  相似文献

Forensic taphonomic studies are regionally specific and improve time since death estimates for medico-legal casework. Within forensic taphonomy and carrion ecology, vertebrate scavengers are under-researched with many studies conducted using multiple, unclothed carcasses. This is a forensically unrealistic experimental design choice with unknown impact. The effect of variation in carrion biomass on the decomposition ecosystem, particularly where vertebrate scavengers are concerned, requires clarification. To assess the effect of carrion biomass load on vertebrate scavenging and decomposition rate, seasonal baseline data for single, clothed ~60 kg porcine carcasses were compared to clothed multiple-carcass deployments, in a forensically relevant habitat of Cape Town, South Africa. Decomposition was tracked via weight loss and bloat progression and scavenging activity via motion-activated cameras. The single carcasses decayed more quickly, particularly during the cooler, wetter winter, strongly correlated with concentrated Cape gray mongoose (Galerella pulverulenta) scavenging activity. On average and across seasons, the single carcasses lost 68% of their mass by day 32 (567 accumulated degree days [ADD]), compared to 80 days (1477 ADD) for multi-carcass deployments. The single carcasses experienced substantially more scavenging activity, with longer visits by single and multiple mongooses, totaling 53 h on average compared to 20 h for the multi-carcass deployments. These differences in scavenging activity and decay rate demonstrate the impact of carrion biomass load on decomposition for forensic taphonomy research. These findings need corroboration. However, forensic realism requires consideration in taphonomic study design. Longitudinally examining many single carcasses may produce more forensically accurate, locally appropriate, and usable results.  相似文献

Policies developed at national levels can be unresponsive to local needs. Often they do not provide the rural poor with access to the assets and services they need to allow them to innovate and adapt to the ways that increased climate variability and change exacerbate challenges to basic securities – food, water, energy, and well-being. In development deficit circumstances, common pool resources are important for climate adaptation purposes. In order for climate adaptation actions to deliver resilience, local perspectives and knowledge need to be recognised and given due priority in formal planning systems. Basing formal adaptive development planning on local strategies can support and strengthen measures that people have been tested and know to work. Local climate adaptation through collective action can address current increases in climate variability, future incremental changes, and the need to transform existing systems to deal with qualitative shifts in climate. These types of adaptation can work in cumulative ways. The results of local adaptation collective action that have benefits of low rivalry between users while being highly inclusive can be considered “local public goods”. Evidence is beginning to emerge that when local governance systems facilitate high levels of participation in planning collective action for climate adaptation, and direct access to resources for implementing local plans, “local public goods” can be created and common pool resources better managed.  相似文献

Indigenous movements have increasingly turned to the global arena to achieve their political goals at the national level. Using the norm diffusion model, the present article analyzes the relationship between the international indigenous rights regime (IRR) and the conceptualizations of indigenous territory used by four Mapuche organizations in Chile over the last 10 years. We find that the organizations draw on the IRR to frame their demand for autonomous territories based on historical Mapuche practices. We identify two conceptualizations: (1) a larger territory with political but not economic autonomy and (2) a smaller natural-cultural space characterized by a distinctive economic logic.  相似文献

The experience of hearing a voice in the absence of an appropriate external stimulus, formally termed an auditory verbal hallucination (AVH), may be malingered for reasons such as personal financial gain, or, in criminal cases, to attempt a plea of not guilty by reason of insanity. An accurate knowledge of the phenomenology of AVHs is central to assessing the veracity of claims to such experiences. We begin by demonstrating that some contemporary criminal cases still employ inaccurate conceptions of the phenomenology of AVHs to assess defendants' claims. The phenomenology of genuine, malingered, and atypical AVHs is then examined. We argue that, due to the heterogeneity of AVHs, the use of typical properties of AVHs as a yardstick against which to evaluate the veracity of a defendant's claims is likely to be less effective than the accumulation of instances of defendants endorsing statements of atypical features of AVHs. We identify steps towards the development of a formal tool for this purpose, and examine other conceptual issues pertinent to criminal cases arising from the phenomenology of AVHs.  相似文献

Building upon interdisciplinary efforts to understand the origins, logic and significance of global cities, this article argues that global cities should be seen as a critical component and outcome of a political project to generate a global market society. Global cities should be seen as the successful implementation of free-market political philosophy, constructed and defended by a particular historical configuration of international society. The historical transformation of urban form signalled by the "global city" concept is tightly bound to the neoliberal restructuring of the world economy in the 1970s, underpinned by US hegemonic power. The first part of this article argues that the distinctive historical origin of global cities has shaped their current trajectories and draws the horizon of their future prospects. Having established the connection between liberal world order and global cities, the second part of the article argues that the contemporary form of the global city is under threat from two sources. The first threat is internal to the global city form itself. Global cities have internalised the contradictory forces of market liberalism. They have registered astonishing economic growth over the last four decades, and generated vast material and intellectual resources. But, at the same time, they have become deeply divided and polarised in ways that threaten the urban fabric. The second source of threat comes from the possible weakening or collapse of liberal world order, with the accelerating decline of US hegemony. Drawing on aspects of Karl Polanyi's analysis of the nineteenth-century "great transformation", the article argues that a number of future trajectories for the global city can be identified in the contemporary moment.  相似文献

ABSTRACT

This article develops a framework for conceptualising authoritarian governance and rule in the Lao People’s Democratic Republic. After introducing the national and academic context, which go a significant way towards understanding the paucity of comparative political work on Laos, we propose an approach to studying post-socialist authoritarian and single-party rule that highlights the key political-institutional, cultural-historical and spatial-environmental sources of party-state power and authority. In adopting this approach, we seek to redirect attention to the centralising structures of rule under the Lao People’s Revolutionary Party, illustrating how authoritarian institutions of the “party-state” operate in and through multiple scales, from the central to the local level. At a time when the country is garnering greater attention than at any time since the Vietnam War, we argue that this examination of critical transitions in Laos under conditions of resource-intensive development, intensifying regional and global integration, and durable one-party authoritarian rule, establishes a framework for future research on the party-state system in Laos, and for understanding and contextualising the Lao People’s Revolutionary Party regime in regional comparative perspective.  相似文献
