Objectives
Sex and age trends in bone mineral density (BMD) play an important role in the estimation of age-at-death (AAD) of unidentified human remains. Current methodologies lack the ability to precisely estimate age in older individuals. In this study, BMD of the cranium and femur measured by DXA were examined to establish their applicability for age estimation in older adults. BMD as measured by DXA, is most commonly used clinically for prediction of osteoporotic fracture risk. We hypothesized that weight-bearing and non-weight-bearing bones, the femur and cranium, respectively, would provide valuable insights for aging.Methods
The sample consists of 32 sets of excised cranial fragments from the Regional Forensic Center, Johnson City, Tennessee and 41 associated crania and femora from the North Carolina Office of the Chief Medical Examiner. All crania and femora were scanned using a Hologic (R) DXA scanner and data were analyzed using Student t-tests, Loess regression, and ANOVA.Results
Student t-tests indicate a significant relationship between the sexes and cranial BMD and a significant relationship between age cohorts and femoral neck BMD. The Loess regression showed different aging patterns in the cranium for females and males older than 55. And the ANOVA showed changes in femoral neck after age 55.Conclusions
These results indicate age and sex dependent changes in BMD especially for individuals over the age of 55, which offers improvement from current aging methods for older individuals. Further research using a larger sample size could improve the predictive capabilities of the model. 相似文献132.
This study concerns the use of crypto-currency with specific reference to the situation in Russia. A variety of such systems exist; Bitcoin, however, is perhaps the best-known example and will be used as synonymous with the concept throughout this article. Our findings not only show how the views of Russian government bodies are formed and developed, but also sheds light on the specific innovative methods which legal entities use for development of the economy. Consideration will be given to recent developments within Russia which has been more active than many countries in seeking to clarify the status of Bitcoin and providing for the regulation of the technology. 相似文献

Decision-making is ever present in all forms of organized human activity. Decisions range from the simple to the complex within large organizations, whether in the nonprofit, public or private sectors. Throughout human history, man has sought to control the results of his decisions, to quantify them, to increase their predictability and to reduce their risks. Three current areas of decision making: risk assessment, chaos theory and strategic management are analyzed in this article. Their interconnectedness and potential as a “new paradigm” is its focus. 相似文献

Abstract In this study, the internal reliability and construct validity of the recently adapted Swedish version of the Novaco Anger Scale (NAS-1998-S; Lindqvist, Dåderman, & Hellström, Social Behavior and Personality, 8, 773–788, 2003), as well as its scale correlations with demographic and criminality variables, were investigated. Construct validity was established by assessing the correlation pattern of the scales of NAS-1998-S with concurrent scales of similar and distinct constructs. Ninety-five male violent prisoners, ranging in age from 18 to 67 years, participated. The results demonstrated good internal reliability, consistent intrascale relationships, and appropriate construct validity of NAS-1998-S. The number of previous convictions had a moderate negative relationship with the capacity of control. Age and education correlated negatively with the NAS-1998-S scales, except Regulation. In addition to psychometric issues, the results were discussed from a clinical perspective on the offender population. 相似文献

Abstract Recently, positive approaches to offender rehabilitation, focusing upon offenders’ strengths, have gained prominence. Proponents have criticized existing rehabilitation models as focusing too much on offenders’ deficits. Goal perspectives, which provide a structure for therapy, may unite these two approaches. The Personal Concerns Inventory: Offender Adaptation (PCI:OA) is a semi-structured interview that identifies offenders’ current concerns or goals. The goals identified by a sample of 129 convicted adult male prisoners are reported here. A range of positive, anti-criminal goals were expressed, including stopping offending, improving self-control, finding and keeping jobs, having stable accommodation, quitting drink and drugs, changing support networks, and finding new leisure pursuits. Furthermore, prisoners expressed life-enhancing goals, such as improving their lifestyle, gaining work experience, having good family relationships, gaining skills, and getting fit and healthy. The PCI:OA may prove useful as a motivational procedure, a basis for developing positive, goal-focused interventions, and a tool for outcome evaluation. 相似文献

ABSTRACTNew Public Management (NPM) reforms are often perceived as technical, with little attention to political and institutional factors. Comparing choices in 20 Indonesian districts, we explore which of four political economic factors influence uptake of NPM-based service delivery reforms. We find that democratic political competition laid the groundwork for political alliances, patterns of patronage, and party provision of benefits that condition reform choices. State-led policy entrepreneurship was evident from education agency technocrats. Public sector modernization may have increased orientation towards performance, with education reforms adopted by districts already achieving relatively good sectoral results. Health reforms were more common in districts providing greater opportunities for citizen participation. The complex interactions among the factors argue for working within these realities, rather than seeing them as impediments to be avoided in a drive for reforms. Education technocrats’ dominance, bolstered by central policy priorities, argues for more nuanced mechanisms for meeting national goals to avoid crowding out responsiveness to local citizens. 相似文献

Geopolitical reasoning privileges the global scale as the locus of spatialised power relations. For the past 20 years, Islam and Islamist politics have figured prominently in geopolitical discourses of international conflict. This paper puts forth a feminist counter-geopolitics that focuses on how Islamist political practices and discourses are written into everyday life and urban spaces. Approaching political activity as comprising both formal voting behaviour and informal associational activities, this study uses survey and focus group data (collected in Istanbul in 1998/99) to explore gender and Islamist politics at national and local scales. Exploring women's activities within both formal and informal urban political spaces, the study reveals some of the ways in which women participate in the daily production and contestation of Islamist politics in Istanbul. 相似文献

The authors report an unusual case of suicide of an anesthesiologist, in which the suicide manner and means depend upon the victim's occupation. This is the first case report published in Italy of a death involving propofol and other drugs. The anesthesiologist was found dead with an empty drip still inserted in the hand and another one near his body. Forensic and toxicological findings suggested that the cause of death was a respiratory depression due to a self‐administration of a rapidly infused lethal drug mixture. Analytical drug quantification was performed by gas chromatography‐mass spectrometry. Blood analysis revealed: zolpidem (0.86 μg/mL), propofol (0.30 μg/mL), midazolam (0.08 μg/mL), thiopental (0.03 μg/mL), and amitriptyline (0.07 μg/mL). Adipose tissue and hair analysis suggested a previous and repeated use of these drugs verifying the fact that in Italy recreational abuse of anesthetic and sedative agents in health care practitioners is becoming an increasing problem. 相似文献
