The authors are exploring degradation patterns of latent fingermarks over time which can be quantitatively determined in a predictable manner by visual means. Several physical degradation parameters for assessing this hypothesis are evaluated. This article analyzes the parameter “minutiae count” as a function of time. Experiment variables included were secretion type (sebaceous‐rich and eccrine‐rich), substrate (glass and plastic), and exposure to light (dark, shade, and direct light). Depositions were sequentially visualized with Titanium Dioxide powder over a period of 6 months, photographed, and number of minutiae recorded. Results revealed a significant decrease of minutiae for eccrine‐rich marks on glass but insignificant for sebaceous‐rich marks on the same surface. However, significant degradation was observed for both types of secretions on plastic. The authors conclude that the distinctive prevalence of minutiae changes over time indicates with a high degree of certainty the hypothesis is valid and deserves additional exploration. 相似文献

Ya‐hui Wang M.D. Tai‐ang Liu Ph.D. Hua Wei M.D. Lei Wan M.D. Chong‐liang Ying B.A. Guang‐you Zhu M.D. 《Journal of forensic sciences》2016,61(2):409-414
The aim of this study was to automatically classify epiphyses in the distal radius and ulna using a support vector machine (SVM) and to examine the accuracy of the epiphyseal growth grades generated by the support vector machine. X‐ray images of distal radii and ulnae were collected from 140 Chinese teenagers aged between 11.0 and 19.0 years. Epiphyseal growth of the two elements was classified into five grades. Features of each element were extracted using a histogram of oriented gradient (HOG), and models were established using support vector classification (SVC). The prediction results and the validity of the models were evaluated with a cross‐validation test and independent test for accuracy (PA). Our findings suggest that this new technique for epiphyseal classification was successful and that an automated technique using an SVM is reliable and feasible, with a relative high accuracy for the models. 相似文献

This article describes a court improvement initiative designed to promote uniformity and improved court practice with the ultimate goal of the improvement of outcomes for children and families. The article focuses on the results of interviews and focus groups conducted as part of the evaluation of this initiative. Twelve jurisdictions were purposively selected to exhibit a range of family court and non–family court jurisdictions in rural and middle‐sized locations. The discussion of the qualitative results focuses on changes in court practice and the impact of the initiative on case time. 相似文献

AGE,GENDER, AND THE CRIME OF CRIMES: TOWARD A LIFE‐COURSE THEORY OF GENOCIDE PARTICIPATION*

This article asks whether genocide follows the age and gender distributions common to other crime. We develop and test a life‐course model of genocide participation to address this question using a new dataset of 1,068,192 cases tried in Rwanda's gacaca courts. Three types of prosecutions are considered: 1) inciting, organizing, or supervising violence; 2) killings and other physical assaults; and 3) offenses against property. By relying on systematic graphic comparisons, we find that the peak age of those tried in the gacaca courts was 34 years at the time of the genocide, which is older than the peak age for most other types of crime. We likewise find that women were more likely to participate in crimes against property and comparatively unlikely to commit genocidal murder. Symbolic–interactionist explanations of crime suggest people desist from crime as a result of shared understandings of the expectations of adulthood. We argue that this process may be turned on its head during genocide as participants may believe they are defending their communities against a perceived threat. Thus, in contrast to other criminological theories suggesting that people must desist from crime to be accorded adult status, some adults may participate in genocide to fulfill their duties as adult men. 相似文献

Arfika Nurhudatiana Ph.D. Adams Wai‐Kin Kong Ph.D. Noah Craft M.D. Ph.D. Hong Liang Tey M.B.B.S M.R.C.P. 《Journal of forensic sciences》2016,61(1):52-58
In child sexual exploitation offenses, the collected evidence images often show the skin of nonfacial body parts of the criminals and victims. For identification in this scenario, “relatively permanent pigmented or vascular skin marks,” abbreviated as RPPVSM, were recently introduced as the basis for a novel biometric trait. This pilot study evaluated the interexaminer variability of RPPVSM identification. Four dermatology physicians were recruited to examine RPPVSM from 75 skin images collected from a total of 51 Caucasian and Asian subjects. The images were separated into 50 reference (“suspect”) images and 25 evaluation (“evidence”) images. The examiners were asked to perform identification by annotating RPPVSM in each of the 25 evaluation images and matching them with the reference images. The rate of misidentification was 0% while the mean rate at which examiners failed to find a match was 6%, indicating the potential of dermatology physicians performing the role of RPPVSM examiners. 相似文献

In 2011, Canadian Members of Parliament refused to transfer a regulatory initiative taken from Argentina that would have required an analysis of potential harm to export markets before authorizing the sale of any new genetically modified seed. This was the purpose of Bill C‐474, which was defeated in the House of Commons. After exploring Argentina's regulatory framework as a source of transfer, this paper combines a multilevel analysis with a typology of policy transfer mechanisms in order to address the complexities underlying this unsuccessful attempt. We explore how the mechanisms of competition and coercion might have impeded the transfer of such an initiative at the international and the macro‐state levels. Moreover, while a policy transfer network in support of the bill called on previous experiences with genetically modified seeds, their efforts appear to have been outweighed by another network using arguments based on the mechanisms of competition, coercion, and mimicry. 相似文献

Abnormal Daily Temperature and Concern about Climate Change Across the United States 总被引:1,自引:0,他引:1
The relatively low level of concern about climate change among Americans has important implications for climate policy. While many studies have examined individual characteristics associated with climate change attitudes, fewer studies have considered the effects of environmental conditions on such attitudes. Here, we use two national samples of American adults to explore the impact of abnormal daily temperatures on levels of concern about climate change. We test the hypotheses that (1) abnormally warm temperatures, and (2) both abnormally warm and abnormally cool temperatures are associated with higher levels of concern. Using a generalized ordinal logit, we find that the quadratic form of deviation from mean temperature on the date of the survey is significantly associated with higher levels of concern, thus supporting the second hypothesis. We discuss several theoretical frameworks that may explain this result including availability bias, mental models, and implicit stimuli, and the implications for climate policy. 相似文献

This study examines the factors that explain public preferences for a set of climate change policy alternatives. While scholarly work indicates a relationship between attitudes and values on views toward specific issues, the literature often examines general support for issues rather than specific policy proposals. Consequently, it is unclear the extent to which these attitudes and values affect specific policy considerations. This project examines public support for five climate change policy options in two national surveys taken three years apart. The empirical analysis reveals that time is a factor and that those who are liberal, have strong ecological values, report greater concern for climate change, and trust experts are consistently more supportive of the climate policy options considered here. The results shed new light on the nuanced views of the American public toward climate change. 相似文献
