We present the case of a man who was last seen leaving to feed his greyhound dogs. He was found dead lying in a yard just outside the gate to one of the dog pens. Holes were present in the fence on both sides of the gate. The holes were of sufficient size to allow the passage of the head and neck of a greyhound to the shoulders. To open the gate one had to bend down to unfasten a latch 45 cm above ground level. Leaning down to unfasten the latch brought one into close proximity to the holes on either side of the gate. The scene and clothing appeared undisturbed. Autopsy (K.A.L.) revealed the cause of death to be blunt throat trauma. The throat trauma was of marked degree and consistent with at least a single heavy crushing injury directed from the front and somewhat below. In addition there were a series of almost vertical light abrasions on one side of the neck. There were minimal injuries to the rest of the body. There were no injuries specific for assault. In an attempt to explain the almost vertical abrasions on the side of the neck, the scene was re-examined by the pathologist. This revealed loose wire strands on the gate post. It is consistent that a fall against this area could account for the almost vertical abrasions on one side of the neck.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

A statistical model is presented and described to test the hypothesis that crime on university campuses bears a systematic and statistically identifiable relationship to a number of independent variables. Of the independent variables tested, the proportion of students living in dormitories and proximity to urban areas with high unemployment seem to influence the amount of crime on campus.  相似文献

African American males experience poor academic performance, high absenteeism at school, and are at increased risk of being involved in violence than other racial groups. Given that the educational outlook for African American males appears bleak, it is important to assess the aspirations of these adolescent males in order to find the gap between aspirations and educational attainment. In order to promote positive development within this population, it is essential that factors that affect African American males be identified. A survey was administered to male students attending elementary, middle, and high schools in a local school district. A cross-sectional study was conducted to examine the career and educational aspirations of African American males. A total of 473 males were surveyed: 45% African American, 22% Caucasian, 13% biracial, and 19% Other (including Asian American, Hispanic, Native American). The results revealed that African American males aspired to attend college at the same rate as other ethnic groups. Also, African American males were more likely to aspire to be professional athletes than males from other ethnic groups. Important factors to consider when designing a program are discussed as well as future research and limitations.  相似文献

The purpose of this article was to assess the overall health behaviors of African American emerging adults who live in a Midwestern city. Two hundred participants, ages 18-25, completed a 129-item survey. Results indicate that African American emerging adults are engaged in relatively healthy behaviors (i.e., physical activity, low substance use). The results also showed that within the emerging adult developmental period, there are differences in behavior for those who are in the younger (18-20) versus those that are older (21-25) in the developmental period. Limitations, future research, and implications for practice will also be discussed.  相似文献

E‐government uses information and communication technology to provide citizens with information about public services. Less pervasive, e‐democracy offers greater electronic community access to political processes and policy choices. Few studies have examined these twin applications separately, although they are widely discussed in the literature as distinct. The authors, Chung‐pin Lee of Tamkang University and Kaiju Chang and Frances Stokes Berry of Florida State University, empirically analyze factors associated with the relative level of development of e‐government and e‐democracy across 131 countries. Their hypotheses draw on four explanations of policy change—learning, political norms, competition, and citizen pressures. All four explanations are strongly linked to nations where e‐government policy is highly advanced, whereas a country’s e‐democracy development is connected to complex internal factors, such as political norms and citizen pressures.  相似文献

What are the apparent research and methodological trends in PAR’s content over the past decade? From the perspective of the journal’s 70‐year history, with its aim to “mesh” practitioner and academic knowledge creation, topical coverage since 2000 reflects striking continuity, emphasizing many of the “bread and butter” administrative issues such as planning, human resources, budgeting, and public management. A marked increase in coverage is apparent in the application of more sophisticated quantitative statistical methodology, as well as in the number of female authors, while the number of practitioner authors declined sharply. Throughout the first turbulent decade of the twenty‐first century, three intellectual themes stood out: evaluations of New Public Management, connections between practitioners and academicians, and responsiveness to immediate social, economic, and political challenges. Given the constant demand for usable knowledge, scholars seem to have marginalized attention to the historical context and epistemological foundations of the study. The central challenge in the years ahead will be to effectively use research methods in response to the big questions of government and society that defy measurement. Since many [empiricists], especially the younger, do not know very much about epistemology, they tend to be quite dogmatic about the one set of canons that dominate them. —C. Wright Mills, 1959  相似文献

The relationship between tort and regulation is dense and complicated. This paper examines diverse approaches to one small element of this relationship: the relationship between regulatory norms and the standard of care in personal injury cases. The lack of clear rules governing that interaction is not surprising: we would never expect the courts to give up the authority (or abdicate the responsibility) to generate private law norms; on the other hand, nor would we expect them to ignore the potential authority and legitimacy of external norms. The strength of external standards is best identified by close scrutiny of the regulation itself. The varying authority of external norms in a private law forum requires engagement with the process by which the external norms were reached. Who and what determined the ‘ought’ of regulation will provide greater insight into the ways in which it should inform the ‘ought’ of tort.  相似文献

In estimating age of juveniles and adolescents, the teeth are employed primarily because of its low variability and less affection by endocrine and nutritional status in development. Demirjian established criteria for evaluating maturity of teeth and his method has been used throughout the world. However, several studies showed the inappropriateness of Demirjian's method on populations other than the one it is based on. Consequently some researchers modified Demirjian's method using data of several different populations. Demirjian himself also published a revised method to overcome other shortcomings of his original method. The aim of this study was to test the validity of Demirjian's and the modified methods (Demirjian's revised, Willems', Chaillet's and new Korean methods) for Korean juveniles and adolescents. 1483 digital orthopantomograms which consist of 754 males and 729 females in the age range of 3-16 years were collected. New age estimation method based on Korean population data was calculated. Dental age was estimated according to each method and the validity was evaluated using the differences between chronological and dental age. The inter- and intra-observer reliability was evaluated to be excellent. Statistically significant difference was observed between chronological and dental age in all the methods for both sexes except new Korean method for both sexes and Demirjian's revised method for males. However, when analyzing absolute and squared value of difference, Willems' method was found to be most accurate followed by new Korean method with slight difference for Korean population for both sexes. In conclusion, both Willems' method and new Korean method conducted by present study were proven to be suitable for Korean population.  相似文献
