The suitability of visual taphonomic methods for digital photographs: An experimental approach with pig carcasses in a tropical climate

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.     

Understanding Dworkin through art: object-based learning and law

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.     

Evidence on voter preferences from unrestricted choice referendums

From 1939 to 1968 Florida used a unique referendum system to set property tax rates for public school operating expenditures at the median millage rate selected by voters. These referendums revealed the entire distribution of voter preferences, which is not possible in the standard up or down referendum. We are the first to use the Florida referendum data. The form of the ballot played an important role in how people voted. Voting machine elections were much more likely than paper ballots to result in rejections of the recommendations of school boards, and produced much greater dispersion of expressed preferences.     

HOW THE WEST LOST ITS BEST OPPORTUNITY FOR RECONCILIATION IN AFGHANISTAN

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.

The Global Trade in Live Cetaceans: Implications for Conservation

Cetaceans—small whales, dolphins and porpoises—have long been popular performers in oceanaria. Captive cetaceans have also been used for research and employed in military operations. In some jurisdictions cetacean display facilities have been phased out or prohibited, and in the US and Hong Kong a high proportion of the whales and dolphins now in captivity have been captive-bred. A large, growing and increasingly opportunistic trade in dolphins and small toothed whales nevertheless exists, its centres of supply having shifted away from North America, Japan, and Iceland to the Russian Federation and developing nations in Latin America, the Caribbean, West Africa, and Southeast Asia. Demand for live captures is being driven by: a new wave of traditional-type oceanaria and dolphin display facilities, as well as travelling shows, in the Middle East, Asia, Latin America, and the Caribbean; increasingly popular programs that offer physical contact with cetaceans, including the opportunity to feed, pet, and swim with them; and the proliferation of facilities that offer ‘dolphin assisted therapy’ to treat human illness or disability. Rigorous assessment of source populations is often lacking, and in some instances live capture is adding to the pressure on stocks already at risk from hunting, fishery bycatch, habitat degradation, and other factors. All too often, entrepreneurs appear to be taking advantage of lax (or non-existent) regulations in small island states or less developed or politically unstable countries to supply the growing global demand for dolphins and small whales. The regulation of trade in live cetaceans under CITES is fraught with problems, not least the poor quality of reporting and the lack of a rigorous mechanism for preparation, review, and evaluation of non-detriment findings.     

The reverse mortgage as an asset management tool

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.     

U.S.-India Space Partnership: The Jewel in the Crown

The new strategic partnership between the United States and India is creating opportunities for security cooperation. A key element in this partnership—U.S.-India space cooperation—will most likely become the defining relationship for international space cooperation around which other space-faring nations will posture. The Indian space program is rapidly developing world-class capabilities and presents itself as a worthy partner. The U.S. space program should be able to provide innovative ideas for fruitful collaboration. Despite these propitious circumstances, there are potential obstacles of cost, security, and risk. The biggest obstacle, however, might simply be bureaucratic intransigence and inertia. The opportunity is here, now, for the United States and India each to add an important new jewel to their crown of international space cooperation activities. Most importantly, this new space partnership should enhance the security and prosperity of the United States, India, and the world.     

The Absolutist Advantage: Sacred Rhetoric in Contemporary Presidential Debate

Sacred rhetoric invokes nonnegotiable convictions rather than reasoned consequences. This form of rhetoric, grounded in transcendent authority and moral outrage, provides an electoral advantage by inspiring greater political engagement and valorizing candidates in the eyes of voters. A study of the language employed in contemporary presidential debates from 1976 to 2004 illustrates that while Democrats made sacred appeals in a few political domains, Republicans employed sacred rhetoric more frequently across a broad range of issues. Democrats have relied more heavily on projected numbers and plans rather than protected values and bounds, often yielding to Republicans an absolutist advantage.     

The Spatial Distribution of Postblast RDX Residue: Forensic Implications

Locating exactly where trace explosive residue samples should be sought during sample collection at bomb scenes is not specified in the published literature or guidelines; in this area, it is generally acknowledged that forensic practices are based on tradition rather than evidence. This study investigated patterns in the spatial distribution of postblast 1,3,5‐trinitro‐1,3,5‐triazocyclohexane residue from a series of unconfined detonations, over a range of sampling sites, and at two different detonation heights. The amount of residue recovered from the sites decreased as a function of distance from the center of the explosion. [Correction added after online publication 27 December 2012: In the preceding sentence, “increased” was corrected to “decreased” to agree with the conclusion of the article.] As the height of the detonations increased, more residues were found from all sampling sites. The findings of this empirical study have a number of important practical implications including determining where residue samples are best sought at crime scenes.
