Prediction of stature from hand measurements   总被引:1,自引:0,他引:1  
A sample of 166 normal adult males and females was taken from different colleges of Assiut representing those living in upper Egypt. Each subject has been studied for measurements of stature (S), hand length (HL) and hand breadth (HB). The data were statistically analysed in order to assess the relationship between stature and hand measurements. The correlation matrix of the study indicates close similarity of the relationship between stature and hand measurements in both sexes and in both sides. A generalized multiple regression equation has been designed to estimate stature from values of hand length and hand breadth regardless of sex or side in the form: S = 34.5 + 5.77 HL + 2.7 HB +/- 5.1. This equation may be helpful to obtain approximate stature when there is difficulty in obtaining a direct measurement or where there is a chance print of a criminal or an amputated hand or arm.  相似文献

Air guns and blank guns may appear relatively harmless at first glance, but they are, in fact, potentially destructive, even lethal, weapons. Approximately 2 to 2.5 million nonpowder firearms are sold annually, and again approximately 12.9 per 100,000 population are treated for such injuries in hospital emergency departments each year in the United States. Unfortunately, these guns are considered to be a toy for children. Therefore, incidents of air gun injuries are gradually increasing. Although such injuries may initially be considered trivial, it may signify severe internal tissue pathologies. These apparently trivial injuries may have catastrophic consequences if unnoticed. In this study, we report 4 cases with head injury due to a shot by these guns. The cases indicate that these people had used the guns belonging to their parents for the purpose of suicide. The cases also show that these machines are not innocent.  相似文献

Sizable migration of workers from North Yemen to other Gulf nations, beginning in the 1960s and continuing through the 1980s, produced a large influx of funds into the nation in the form of workers' remittances. This produced a general rise in living standards and improved balance-of-payment statistics, but also greatly increased corruption as poorly-paid officials struggled to make a living in the inflated economy and private parties sought to circumvent economic regulations. Reform efforts met with apathy or even violence, and corruption eventually reached systematic if not systemic levels. Many Yemeni migrants have recently been repatriated in the wake of the Gulf War. Whether or not this will reduce corruption depends upon many factors, such as the activities of the nation's increasingly independent press and the successful exploitation of oil and gas reserves.  相似文献

In light of past research being targeted to find specific particles which may be similar to gunshot residue (GSR), this project was formulated to detect any possible particulate by random particle fallout onto substrates at firework displays and to assess the impact this may have on GSR evidence. Firework residue was collected at a display site, from amongst spectators as well as from the author's hair 90min after the display. SEM-EDX analysis has detected such particulate in all three scenarios, with the firework particle population at large providing a solid ground for discrimination from GSR. Wind dispersal was found to decrease the particle population and subsequently, the latter's discriminatory power. Some particles, if treated individually were found to be indistinguishable from GSR. Findings also include residues which may mimic strontium based GSR as well as GSR which may be mixed with that from previous firings. The continuous changes made to primer and propellant compositions by manufacturers also call for greater consideration when classifying particles as originating from pyrotechnic devices. Furthermore, authorities such as police forces should be made more aware about the incidence of such particle transfer in firework related periods.  相似文献

Shame management is purported to be part of the healing process that is a goal of restorative justice. However, the development of shame management capacities and how they are engaged in conflict resolution remains a relatively understudied phenomenon. This study examines how shame management (acknowledgment and displacement) is employed by children as they move into and out of cultures of school bullying. The analysis is based on self-reported changes in bullying experiences of 335 Australian children over a three-year period. Children were classified into bully, victim, bully-victim, nonbully-nonvictim, or residual conflict groups. Shame displacement and bullying tolerance accompanied transition into bullying. Shame acknowledgment and control of bullying marked desistence from bullying. Effects of shame management and social control were not uniform across groups. Findings indicate that interventions to change behaviour need to be flexible and responsive to prior bullying experiences so specific risk and protective factors can be targeted. This study demonstrates that responsiveness to context, building socially responsible relationships, and adaptive shame management are all integral to behaviour change, supporting the use of restorative justice as a way of dealing with school bullying as well as other forms of harm.  相似文献

Eyewitnesses often have to recognize the perpetrators of an observed crime from identity lineups. In the construction of these lineups, a decision must be made concerning where a suspect should be placed, but whether location in a lineup affects the identification of a perpetrator has received little attention. This study explored this problem with a face-matching task, in which observers decided if pairs of faces depict the same person or two different people (Experiment 1), and with a lineup task in which the presence of a target had to be detected in an identity parade of five faces (Experiment 2). In addition, this study also explored if high accuracy is related to a perceptual pop-out effect, whereby the target is detected rapidly among the lineup. In both experiments, observers?? eye movements revealed that location determines the order in which people were viewed, whereby faces on the left side were consistently viewed first. This location effect was reflected also in observers?? responses, so that a foil face on the left side of a lineup display was more likely to be misidentified as the target. However, identification accuracy was not related to a pop-out effect. The implications of these findings are discussed.  相似文献

A 23 year old man presented with intestinal evisceration from stab injury to the left side of the abdomen with a hand-held cow horn at a local night party. He complained of severe abdominal pain and bleeding at the site of injury. He was hemodynamically stable. At emergency exploration, the eviscerated bowel was viable with no adjacent mesenteric tear. Other intra abdominal organs were normal. The eviscerated bowel was lavaged and reduced into the abdomen through the 7 cm anterior abdominal wall laceration. The laceration was repaired and abdomen closed in layers. Post operative recovery was uneventful. The hand-held cow horn can easily be concealed and may pass through security checks undetected. It should be added to the ever increasing list of weapons of small scale terror.  相似文献
