Forensic practitioners are recommended to dark adapt their eyes prior to conducting evidential searches in the dark. The dark adaptation process remains poorly standardised across the discipline, with little quantified regarding the benefits of such preparative steps. Herein, we report the findings of a study that recruited 50 participants to assess the effectiveness of the Crime-lite Eye?, a darkness adaptation device developed to assist forensic practitioners both in the laboratory and in field. Participants were tasked with searching for the fluorescent signatures left by reaction of 1,8-diazafluoren-9-one (DFO) with amino acids, in a manner akin to the fluorogenic fingerprint treatment of porous evidence. Using an Epson Stylus Photo R265 inkjet printer, ink cartridges were filled with alanine solutions of various concentrations, allowing different motifs to be printed onto copy paper and subsequently developed using DFO. Participants searched for this ‘evidence’ both with and without dark adapted vision. On average, participants were able to locate and correctly recognise 16% more evidence once dark adapted using the Crime-lite Eye?.The increase in evidence located by participants once dark adapted suggests that crime scene officers should be dark adapting in order to visualise as much as possible. The time taken to dark adapt, 10?min on average during this study, is not excessively long, and should not significantly slow the investigation. 相似文献
Although the past decade has witnessed the rise of studies on Chinese evaluations of the police, rural villagers’ assessments of the police remain under-researched. Drawing upon performance theory and survey data from China’s countryside, this study tested whether variations in satisfaction with government performance and life are linked to villagers’ and officials’ trust in county and local/town police. We found that villagers displayed lower levels of trust in the police than local officials. Higher satisfaction with government performance and integrity were associated with greater trust in county police among both villagers and officials. Villagers’ greater satisfaction with crime control and safety led to their stronger trust in both county and town police, but such satisfaction was not significantly related to officials’ trust in both levels of police forces. Rural residents’ generalized trust and particularized trust were associated with a greater likelihood of viewing the police as trustworthy. Meanwhile, female respondents, both villagers and officials, and higher-income officials were more likely to view the police as trustworthy. Directions for future research and policy are discussed.
Anthropological contribution to forensic sciences has been multifaceted and the progress has been remarkable in the last quarter of this century. The field has brought together scientists from all around the world. The purpose of this paper is to present a special issue on forensic anthropological research. Some of the papers cover age estimation from the ankle and knee epiphyses (India), basioccipital synchondrosis (also India), sternal end rib metamorphosis in Turks, and histomorphometry of the Japanese. Sex determination from the South African cranium and Mongoloid humerus are the subject of two papers. Factors of individualization include a comparison of photographic images using neural network, bone trabecular radiography, determination of handedness from the humerus, time since death using 210Po to 210Pb ratio, and changes in the mineral content of bone after burial. From the papers in this special issue it can be concluded that there will be integration of many areas of forensic sciences to deal with anthropological issues in the 21st century. Estimation of time since death will be based on new and more precise techniques. Further research is needed to develop population specific osteological standards for populations of Africa, central and southeast Asia and Pacific region. In addition, there will be an increased interest in the study of living people. 相似文献
The I?can's phase method for the estimation of adult age at death from the sternal extremity of the fourth rib was introduced in 1983. Over the years, numerous tests have confirmed the reliability of this technique on varied samples. However, no large scale study has been conducted to test the application of this method on a modern white sample geographically, genetically, and culturally diverse from the American white database. Therefore, the purpose of this paper is to apply rib phase standards to a Turkish sample to test if the progression of morphological changes follow the same age sequence. Using a sample of 150 males and 144 females of known age at death, each rib was phased using the standards developed by I?can and associates in 1984 and 1985. The phase estimations were then subject to an analysis of variance. The results of the study indicated that Turkish ribs show the same morphological characteristics that define the phases at nearly identical ages. Variation as measured by the standard deviation increased from phase 5 on in both sexes. In conclusion, this study demonstrated that the rib phase standards can be accurately applied to Turks. Investigations of this nature are vital because one cannot assume that a method developed from one group is applicable to a distant population, especially in medicolegal proceedings. 相似文献
A fatal case of myoglobinuria complicating heroin addiction is described. Clinically the patient had no overt symptoms of rhabdomyolysis. Pathologists should be alerted to this rare complication in heroin addicts who die of no apparent cause. The antimyoglobin immunoperoxidase technique is useful in confirming the diagnosis. 相似文献
Sudden unexpected nocturnal death syndrome (SUNDS) is a distinct clinical entity in previously healthy, young, Southeast Asian males. It is well known in the Philippines and more recently recognized in the U.S. by nonspecific autopsy findings, with no evidence of underlying disease and absence of toxic drug or alcohol levels. In 1973-89, 14 cases of apparent SUNDS came to coroner's autopsy in the Commonwealth of the Northern Marianas (CNMI) and Guam. All 14 cases, with the exception of one Yapese, were previously healthy, male Filipinos, aged 23 to 55, who were either found dead in bed, or described by their colleagues as having nocturnal seizure activity consisting of gurgling, frothing, and tongue biting immediately prior to death. Autopsy findings showed no anatomic findings to account for death. Comprehensive serum and urine drug analyses were negative. All decedents showed absence of significant atherosclerosis or grossly detectable structural cardiac anomaly, while four showed cardiomegaly. Migrants from Southeast Asia carry with them a pre-disposition to this syndrome, which appears to decline with longer residence in the new country. The mechanism of death in SUNDS is believed to be ventricular fibrillation, possibly precipitated by sudden sympathetic discharge. Studies suggest at least some deaths may be associated with an abnormal cardiac conduction system. Acute pancreatitis has been a finding in some series, but not our cases. Why the condition is virtually limited to males and seemingly sleep-triggered, has not been adequately explained. Stress and depression are believed to be predisposing factors. 相似文献
The economic rise of the BRICS (Brazil, Russia, India, China and South Africa) inevitably leads to a redistribution of power in the international system. Chinese leaders today accord a considerable priority to this group, and there are elements of realism, liberalism/institutionalism and constructivism in their approach. This article intends to study China's policy towards BRICS and examine the above elements so as to better understand how the Chinese leadership perceives China's role in the international system, and how it seeks to articulate its interests and enhance its influence. 相似文献
This article examines the patterns and changes in public perceptions of domestic income inequality in Hong Kong in the past two decades and explains individual variations in these perceptions. It found that the perceived seriousness of income disparities had been persistently high, while the perceived unjustness of income disparities showed a fluctuating trend. Our findings lent partial support to the structural position thesis that the privileged groups are less likely than the underprivileged groups to consider existing income disparities to be serious and unjust. Nonetheless, the popular understanding of poverty is still biased towards ‘individual’ explanations, and this perhaps explains why the government is less willing to tackle the economic and political foundations of poverty in Hong Kong. 相似文献
The aim of this study is to define organizational citizenship levels of physicians working in public hospitals. The population of the study consists of the physicians employed in the hospitals run by the Ministry of Health in Istanbul. The Organizational Citizenship Level Scale was used for the collection of data. It was found that the participants’ organizational citizenship levels were the highest in the “conscience” subsection and the lowest in the “praising the organization” subsection. Findings of this study provide clear information for the decision-makers and hospital managers in developing working conditions of physicians in public hospitals. 相似文献
