Trading places     
This paper examines effects that alternative voting systems can have on electoral outcomes in multicandidate elections. Using ballots collected from a county Republican Party special election, we recount the votes using preference-based voting systems and compare the results to the special election outcome. Relative rankings of candidates change across vote counting rules and voting systems. Because candidates trade places depending on rules, there are strong strategic implications for candidates and for those establishing the rules.  相似文献

Rupture of a varicose vein is a rare cause of sudden death. It occurs when the failure of venous valves causes an increase in venous pressure great enough to provoke rupture of the blood vessel. When it does happen, the victim is often found surrounded by a pool of blood, and the examination of the scene can mislead the forensic team to think of violent death. Until now, the bloodstain patterns in these fatal cases have not been described. An examination of the bloodstain pattern in a case of fatal varicose vein rupture in an 84-year-old man is here reported.  相似文献

Thirty‐eight participants took part in a study that investigated the potential cascading effects of initial exposure to extraneous context upon subsequent decision‐making. Participants investigated a mock crime scene, which included the excavation of clandestine burials that had a male skeletal cast dressed either in female or gender neutral clothing. This was followed by a forensic anthropological assessment of the skeletal remains, with a control group assessing the same male skeletal cast without any clothing context. The results indicated that the sex assessment was highly dependent upon the context in which participants were exposed to prior to the analysis. This was especially noticeable in the female clothing context where only one participant determined the male skeletal cast to be male. The results demonstrate the importance of understanding the role of context in forensic anthropology at an early stage of an investigation and its potential cascading effect on subsequent assessments.  相似文献

In the context of increased scrutiny of the methods in forensic sciences, it is essential to ensure that the approaches used in forensic taphonomy to measure decomposition and estimate the postmortem interval are underpinned by robust evidence-based data. Digital photographs are an important source of documentation in forensic taphonomic investigations but the suitability of the current approaches for photographs, rather than real-time remains, is poorly studied which can undermine accurate forensic conclusions. The present study aimed to investigate the suitability of 2D colour digital photographs for evaluating decomposition of exposed human analogues (Sus scrofa domesticus) in a tropical savanna environment (Hawaii), using two published scoring methods; Megyesi et al., 2005 and Keough et al., 2017. It was found that there were significant differences between the real-time and photograph decomposition scores when the Megyesi et al. method was used. However, the Keough et al. method applied to photographs reflected real-time decomposition more closely and thus appears more suitable to evaluate pig decomposition from 2D photographs. The findings indicate that the type of scoring method used has a significant impact on the ability to accurately evaluate the decomposition of exposed pig carcasses from photographs. It was further identified that photographic taphonomic analysis can reach high inter-observer reproducibility. These novel findings are of significant importance for the forensic sciences as they highlight the potential for high quality photograph coverage to provide useful complementary information for the forensic taphonomic investigation. New recommendations to develop robust transparent approaches adapted to photographs in forensic taphonomy are suggested based on these findings.  相似文献

This article explores object-based learning (OBL), a burgeoning pedagogical approach in higher education. Object-based learning engages students’ pre-existing visual and conceptual literacy as a gateway to work through difficult threshold concepts. The article advocates this exciting learning model in law by articulating what it is, explaining how it can be applied through the example of teaching Dworkin in a jurisprudence module. The article introduces OBL approaches, details how it is relevant to jurisprudential teaching as well as its scope for application across legal teaching. It explains how such an approach moves away from transmission modes of teaching into transformational ones, accessing students’ abstract web of comprehension in conjunction with text-based learning to produce more imaginative and creative critical thinking skills.  相似文献

The article asserts that the current situation in Afghanistan could have been quite different. Well before 9/11, Abdul Haq, a Pushtun and a veteran commander in the war against the Russians, put forward a plan to overthrow the Taliban from within, a plan which had significant support inside Afghanistan. Haq, who was subsequently killed by the Taliban, was ignored by the West, which chose instead to intervene militarily, to support the war lords of the Northern Alliance and thus to marginalise the Pushtuns. The 2002 Loya Jirga was the crucial moment for the West, which failed to realise that Pakistan had its own, very different agenda.  相似文献

Potentially preventable crimes resulting from failures in criminal record checking and recording emerged as problematic in the eighteenth century and have continued up until the present day. Ranging from child abuse to murders, reports suggest that if criminal records had been evident, in some cases unlawful acts may have been prohibited. The historical background to the emergence of criminal record collection and checking in the United Kingdom (UK) is analysed from the mid-eighteenth century. This time period is chosen because it marks a pivotal change in the treatment of criminals, crimes and the start of the policing system in the United Kingdom. As a result of growing societal concerns over public safety and changes in the legal system, the approach in which criminal records have been utilised in employment decision-making has evolved most rapidly in the late twentieth and early twenty-first centuries. The recording, storing and sharing of criminal record information has received most attention only in the past decade. Developments in recruitment-vetting procedures for the protection of vulnerable persons have only emerged in the last 50 years to manage such crimes in the United Kingdom. In 2002 the Criminal Records Bureau (CRB) was established in the United Kingdom to ensure safer recruitment decisions could be made in society. However, the question remains whether or not these practices have been and are effective.  相似文献

Abstract

Reverse mortgages are usually seen as a vehicle for increasing the income of poor, elderly households. This perspective, coupled with the relatively slow growth of reverse mortgage programs, has led some observers to question the growth potential of the reverse mortgage market. This article presents a more expansive view of reverse mortgages as a financial tool for tapping housing equity for various purposes and at various stages in the life cycle.

Three market segments for reverse mortgages are discussed: elderly persons living alone, other elderly households, and non‐elderly households. Potential uses include turning housing equity into personal human capital investment accounts, enabling children to provide care for their disabled parents, funding elderly households’ long‐term care insurance, and sustaining consumption. Recent progress in product development and availability and political pressures to find private financing for health and long‐term care suggest that the reverse mortgage market has considerable growth potential.  相似文献

Abstract

A distinctive feature of the security landscape in western Europe of the post-Cold War era is that the dividing line between internal and external security has become increasingly obsolete—mainly as a consequence of the growing importance of transnational as well as other challenges to security which defy the distinction between domestic and international security. This article examines this convergence of internal and external security agendas from the perspective of the coercive apparatus of western European countries, pointing to a militarisation and externalisation of policing, and an internalisation and ‘policisation’ of soldiering: while police forces are taking on military characteristics, and are extending their activities beyond the borders of the state, military forces are turning to internal security missions, and are adopting certain police features. Moreover, agencies which have traditionally been located at the interface between police and military forces, i.e. gendarmerie-type or paramilitary forces, are assuming an increasingly important role.  相似文献
