Cash‐and‐valuables‐in‐transit (CViT) robberies have become a substantial problem—especially in the current global economy. Over £19.4 million were stolen in 2008 and £17.1 million in 2009 in the United Kingdom alone. The transportation of cash and valuable items between financial institutions has long been a target of robberies in the U.K. After a robbery has occurred, police collect evidence in the form of ink‐stained currency. These stained notes are submitted for analysis. Samples are subjected to polymerase chain reaction in order to amplify any possible botanically derived DNA markers present on the notes. After amplification, capillary electrophoresis allows for the deciphering of the “DNA profile.” The DNA profile is then linked to a particular cash box, and this information is compared with records of whether or not that box had been stolen. The cases below are three such instances where botanically marked currency was used to help solve robberies. 相似文献

In this paper we analyse Stegdetect, one of the well-known image steganalysis tools, to study its false positive rate. In doing so, we process more than 40,000 images randomly downloaded from the Internet using Google images, together with 25,000 images from the ASIRRA (Animal Species Image Recognition for Restricting Access) public corpus. The aim of this study is to help digital forensic analysts, aiming to study a large number of image files during an investigation, to better understand the capabilities and the limitations of steganalysis tools like Stegdetect. The results obtained show that the rate of false positives generated by Stegdetect depends highly on the chosen sensitivity value, and it is generally quite high. This should support the forensic expert to have better interpretation in their results, and taking the false positive rates into consideration. Additionally, we have provided a detailed statistical analysis for the obtained results to study the difference in detection between selected groups, close groups and different groups of images. This method can be applied to any steganalysis tool, which gives the analyst a better understanding of the detection results, especially when he has no prior information about the false positive rate of the tool. 相似文献

Abstract THIS STUDY is about second‐year students’ self‐assessment in law. Its aims were to test how closely the assessment by the students of their own work matched that of their tutor, to give the students an insight into the “marking process” (which research has shown improves learning), to help the students excel in their examination, to find out whether the male students did better than the female students in their assignment and subsequent examination, and to see how far staff time could be saved. The following were found: there was a high level of agreement between the students’ own marks and those of the tutor, there was generally no significant over‐estimation of assignment marks by the students, the participants did better than the non‐participants in the subsequent examination, the female students did much better than the male students in the assignments as well as the examination (although the participants in general did not do better in their examination than they did in their assignment) and considerable staff time was saved. The findings are discussed in the light of previous research. 相似文献

This article demonstrates empirically that widespread convergence in the degree of industrialization between former First
and Third World countries over the past four decades hasnot been associated with convergence in the levels of income enjoyed on average by the residents of these two groups of countries.
Our findings contradict the widely made claim that the significance of the North-South divide is diminishing. This contention
is based on a false identification of “industrialization” with “development” and “industrialized” with “wealthy”. Elaborating
from elements of Joseph Schumpeter’s theory of innovation, Raymond Vernon’s product cycle model, and Pierre Bourdieu’s concept
ofillusio, the article offers an explanation for the persistence of the North-South income divide, despite rapid Third World industrialization
and despite dramatic changes in the world political-ideological context for development (that is, the shift around 1980 from
the “development” project to the “globalization” project or “Washington Consensus”). While emphasizing the long-term stability
of the Northern-dominated hierarchy of wealth, the article concludes by pointing to several contemporary processes that may
destabilize not only the “globalization project”, but also the global hierarchy of wealth that has characterized historical
capitalism.

The right to health was codified in Article 12 of the International Covenant on Economic, Social and Cultural Rights as an individual right, focusing on individual health services at the expense of public health systems. This article assesses the ways in which the individual human right to health has evolved to meet collective threats to the public's health. Despite its repeated expansions, the individual right to health remains normatively incapable of addressing the injurious societal ramifcations of economic globalization, advancing individual rights to alleviate collective inequalities in underlying determinants of health. By examining modern changes to underlying determinants of health, this article concludes that responding to globalized health threats necessitates a collective right to public health. 相似文献

Economic crisis has been a central catalyst to Third Wave democratic transitions by contributing to authoritarian breakdown,
yet crises in oil-exporting states have generally failed to catalyze such breakdowns, which are a crucial precondition to
democratization. This article argues that oil wealth produces two distinct political trajectories, depending on its timing
relative to the onset of late development. The dominant trajectory in the oil-exporting world is durable authoritarianism
which has forestalled all but a few regime collapses. And, when the alternate trajectory produces vulnerable authoritarianism,
oil-catalyzed authoritarian breakdown tends to generate new authoritarian regimes. I use case materials from Iran and Indonesia
during the 1960s and 1970s to illustrate the two oil-based trajectories, and I conduct a broader test of the theory against
data for 21 oil-exporting, developing countries, which provides suggestive support for a two-path theory of oil-based aturhoritarian
persistence.

His first book,Hard Times in the Land of Plenty: Oil, Opposition, and Late Development, is under contract with Cornell University Press. Other work has appeared in theAmerican Journal of Political Science, World Politics, and theJournal of International Affairs. He is currently at work on a book-length study of durable authoritarianism with Jason Brownlee (University of Texas-Austin)
and on a study of the conditions under which democracy can consolidate in oil-rich countries with Joseph Kraus (University
of Florida).
