Forensic archaeologists and criminal investigators employ many different techniques for the location, recovery, and analysis of clandestine graves. Many of these techniques are based upon the premise that a grave is an anomaly and therefore differs physically, biologically, or chemically from its surroundings. The work reviewed in this communication demonstrates how and why field mycology might provide a further tool towards the investigation of scenes of crime concealed in forest ecosystems. The fruiting structures of certain fungi, the ammonia and the postputrefaction fungi, have been recorded repeatedly in association with decomposed mammalian cadavers in disparate regions of the world. The ecology and physiology of these fungi are reviewed briefly with a view to their potential as a forensic tool. This application of mycology is at an interface with forensic archaeology and forensic taphonomy and may provide a means to detect graves and has the potential to estimate postburial interval. 相似文献

Der Beitrag befasst sich mit den exogenen Bestimmungsfaktoren der Koordination raumwirksamer Politiken anhand der vier Agglomerationen von Basel, Bern, Lausanne und Genf. Ein Vergleich von entsprechenden Outcomes zeigt markante Unterschiede zwischen den vier Städten. Nach einer kurzen Kritik der Binnenorientierung gängiger Governance-Ansätze werden die drei exogenen Erklärungsansätze der politischen Geographie, des Institutionalismus und der politischen Kultur in vier Thesen beschrieben. Deren Exploration weist die Wichtigkeit von Kontextvariablen bei der Untersuchung von Ressourcen-Regimen aus. So ist eine Abhängigkeit der inhaltlichen Koordination von soziokulturellen, geographischen und historischen Faktoren auszumachen. Dagegen ist der Zusammenhang mit der Einschätzung der institutionalisierten Koordination nicht eindeutig, was die Vermutung nahelegt, dass im Falle der prozeduralen Koordination die endogenen Faktoren stärkere Erklärungskraft besitzen und die Regime Analysis mithin das geeignetere Mittel zu ihrer Untersuchung darstellt. 相似文献

Isotope ratio mass spectrometry as a tool for forensic investigation (examples from recent studies).
James F Carter Richard Sleeman Jenny C Hill Fay Idoine Emma L Titterton 《Science & justice》2005,45(3):141-149
The versatility of isotope ratio mass spectrometry is demonstrated by reference to diverse case studies. Variations in the natural isotopic composition of non-biological, organic materials are compared as a means by which samples may be associated or discriminated. These techniques may be used to augment or compliment conventional forensic methodologies. delta13C analysis was used to demonstrate that different masking tape had been recovered in two, apparently similar cases, involving the smuggling of money. Visually similar ecstasy tablets were compared by consideration of the delta13C and delta15N composition of MDMA extracted from the tablets. Although only a limited number of tablets were analysed, the isotopic similarity between two different seizures was sufficient to induce a guilty plea from a person suspected of possessing both. A combination of delta2H, delta13C, delta15N and delta18O together with GC-MS analyses were applied to small samples of seized heroin. Although GC-MS analysis indicated differences between the chemical composition of two of the heroin samples, isotopic analysis suggested similarities, which were confirmed by further delta2H, delta13C and delta18O isotopic analysis of the clingfilm in which the samples were wrapped. 相似文献

I report estimates for a fixed-effects model of country-level Gini coefficients as a function of economic freedom along with relevant control variables. Gini coefficients are drawn from the UNU/WIDER World Income Inequality Database Version 2.0a, while economic freedom is measured by the Fraser Institute's Economic Freedom of the World index. Controls are included for per capita income, political structure, education, demographics, and industrial composition. Over a broad range of freedom, the estimated relation between economic freedom and income inequality is positive, statistically significant, but relatively inelastic. 相似文献

A key question in understanding regulation through independent intermediaries is the extent to which intermediary actions are either coordinated, thereby supporting consistency in regulatory application, or uncoordinated, leading to monitoring and enforcement disparities. This paper examines professional associations as one mechanism by which policy action may be coordinated in decentralized arrangements. Professional associations provide means and venues for members to interact, offer training and education that develops shared understanding of policy directives, are collective representation bodies for professional members, and may play an important role in establishing and enforcing collective standards for appropriate behavior. We examine these functions in the decentralized administration of United States organic food certification, focusing on two relevant professional associations – the Accredited Certifiers Association and the International Organic Inspectors Association. Drawing on multiple methods, including interviews and survey data, our findings indicate that professional organic certification associations provide valuable education and training, disseminate information, and facilitate knowledge sharing among administrative entities and with regulatory authorities. We conclude with a discussion of the prospects and limitations of professional associations for third‐party regulation, and how accounting for professional association functions can improve our understanding of regulatory intermediary coordination and conduct. 相似文献

Among the more recognizable programs related to natural and sustainable food is the United States Department of Agriculture’s National Organic Program. Although the robustness of the organic food market is difficult to contest, many debate the extent to which U.S. organic policy outcomes adequately serve consumers and the organic agriculture producers they rely on. This paper engages the debate from the perspective of certified organic producers. Drawing on the results of a nationwide survey of USDA‐certified producers, we first provide a snapshot of how producers assess the environmental, consumer, and market impacts of U.S. organic food policy. We then examine the extent to which organic producers’ policy impact perceptions are associated with their alignment with an “organic ethos”—understood as producers’ commitment to core organic principles and the organic movement. The paper highlights producers’ values as perceptual filters and cognitive mechanisms that help shape producers’ policy impacts perceptions, illustrating a contributing factor to the enduring nature of organic policy debates. 相似文献

Information sharing research has largely focused on capturing operational practices related to the exchange of information. A noticeable shortcoming of this developing literature is the lack of scholarly attention focused specifically on analytic personnel. The present study employs semi-structured interviews with 23 personnel that comprise the analytic unit within a regional fusion center located in a large metropolitan area in the United States. Findings indicate that there is significant ambiguity surrounding the organizational and geographic audiences to which intelligence products should be tailored. Moreover, it appears information sharing is sparse and reliant upon personal relationships between analysts and external organizations. Lastly, analysts do not receive feedback pertaining to the content and effectiveness of intelligence products created. These findings may be generalized to other analytical organizations whose primary goal is to gather, analyze and disseminate intelligence. Action steps for policymakers are provided. 相似文献

This article uses the Palazzo della Civiltà Italiana (PdCI) in the Rome suburb of EUR as a case study to explore how Italians have negotiated the “difficult heritage” of Fascism since 1945. Following Sharon Macdonald, the paper understands the term difficult heritage to refer to a historically significant past that remains materially visible through sites, buildings, artworks, monuments and other artefacts, but which is difficult to reconcile with “a positive, self-affirming contemporary identity”. The paper employs a biographical approach to reveal and analyse the post-Fascist “lives” of the PdCI, one of the most recognisable — and, in recent decades, most admired — examples of Fascist monumental architecture in Italy. With reference also to other examples of difficult Fascist heritage in Italy, and to sites associated with the difficult heritage of Nazism in Germany, the paper offers new insights into how Italy has confronted its Fascist past and places the Italian experience of difficult heritage within the broader international context. 相似文献
