Barefoot impressions--a preliminary study of identification characteristics and population frequency of their morphological features 总被引:3,自引:0,他引:3
Footprint impressions of 107 male adults ranging in age from 19 to 67 years were recorded and examined. Included in this study were foot impressions from a pair of monozygotic twins as well. The impressions were recorded and converted into a set of indices which essentially are width-versus-length ratios of prominent features of the human foot. These indices were then correlated to yield probability values for use in this study and for comparison to data published by previous investigators Qamra, Abbott, Lovejoy, Cassidy, and Robbins. Friction ridge minutae were not considered in this study. Crease marks, well impressions, and toe step measurements were considered, but not incorporated in the probability values, because of the unique aspect of these features and the inability, at present, to convert these features to mathematical indices. These features do, however, introduce a subjective nature to the analysis scheme. This study uses the combined index probabilities of foot impressions so that the data generated can be used to assign a given probability that a particular foot impression, even without clear definable individual features, can be linked to the person who made the impression. 相似文献

The current study sought to extend the knowledge about factors associated with NGRI acquittees' maintenance of a conditional release after hospital discharge. The medical and forensic records of 125 NGRI acquittees were reviewed to collect a variety of demographic, clinical, criminal, and aftercare factors. A hierarchical survival analysis approach to determining success was compared to data analysis strategies typically employed in the area. Survival analysis, which accounts for both conditional release success status and time on conditional release, revealed that minority status, substance abuse diagnosis, and a prior criminal history were the factors that significantly predicted conditional release revocation. Treatment and policy implications of these results are discussed. 相似文献

‘Ground-Truthing’ Chinese Development Finance in Africa: Field Evidence from South Africa and Uganda
A new methodology, Tracking Underreported Financial Flows (TUFF), leverages open-source information on development finance by non-transparent, non-Western donors. If such open-source methods prove to be valid and reliable, they can enhance our understanding of the causes and consequences of development finance from non-transparent donors including, but not limited to, China. But open-source methods face charges of inaccuracy. In this study we create and field-test a replicable ‘ground-truthing’ methodology to verify, update, and improve open-source data with in-person interviews and site visits in Uganda and South Africa. Ground-truthing generally reveals close agreement between open-source data and answers to protocol questions from informants with official roles in the Chinese-funded projects. Our findings suggest that open-source data collection, while limited in knowable ways, can provide a stronger empirical foundation for research on development finance. 相似文献

Using the test cases of Afghanistan and Iraq, this study illustrates how alliances work to mitigate the conflicting frames that party structure and media access provide in the Global War on Terror, which leads to more cohesiveness in the North Atlantic Treaty Organization (NATO)–led coalition in Afghanistan as opposed to the U.S.-led coalition in Iraq. The approach utilized here extends the theory on alliance capability and uncertainty by arguing that alliances reduce uncertainty among member states on a strategic objective. This is particularly relevant when examining asymmetric, limited conflicts, where party structures and media access can work to disseminate conflicting frames to a domestic populace, who then can pressure their leader to withdraw from a coalition. The implications of these findings lend support to the continued relevance of NATO in the twenty-first-century security arena. 相似文献

How are poverty analyses and poverty traps assessments affected by the choice among conventional methods of asset index construction? To address this question, this article uses panel data from four sites in the Millennium Villages Project (MVP) in Malawi, Tanzania, Mali and Ghana to study the relationship between eight asset indices and the sensitivity of findings related to poverty rates, poverty transitions and poverty traps to the index used. We find that although estimations of poverty rates and transitions are largely consistent across indices, evidence of poverty traps can be conditional on which asset index is used. The asset indices studied include structural income, principal components, factor analysis and a reduced set of assets reflecting the portfolio assessed in the Demographic Health Survey (DHS) data. 相似文献

Vladimir Putin has managed to achieve strikingly high public approval ratings throughout his time as president and prime minister of Russia. But is his popularity real, or are respondents lying to pollsters? We conducted a series of list experiments in early 2015 to estimate support for Putin while allowing respondents to maintain ambiguity about whether they personally do so. Our estimates suggest support for Putin of approximately 80%, which is within 10 percentage points of that implied by direct questioning. We find little evidence that these estimates are positively biased due to the presence of floor effects. In contrast, our analysis of placebo experiments suggests that there may be a small negative bias due to artificial deflation. We conclude that Putin’s approval ratings largely reflect the attitudes of Russian citizens. 相似文献

Considerable research has examined public opinion of the death penalty using simplistic questions such as, “Do you favor or oppose the death penalty.” Simply categorizing people into favoring or opposing capital punishment does little to address the array of factors and circumstances that are part of every murder. We examine variables concerning the nature of homicides from a set of 40 murder vignettes used to gauge respondents’ level of support for capital punishment in murder cases. The data are structured such that vignette responses are nested within individuals, meaning a multi-level analysis is appropriate. We used HLM to explore how vignette-level or homicide related characteristics influence support for the death penalty, as well as how individual-level characteristics condition these factors. Analyses revealed that individual-level variables were non-significant when analyzed independently; however, cross-level interactions indicated significant individual-level influences on homicide-level characteristics as they relate to respondents’ support for the death penalty. 相似文献
