In the forensic context, teeth are often recovered in mass disasters, armed conflicts, and mass graves associated with human rights violations. Therefore, for victim identification, techniques utilizing the dentition to estimate the first parameters of identity (e.g., age) can be critical. This analysis was undertaken to apply a Bayesian statistical method, transition analysis, based on the Gompertz-Makeham (GM) hazard model, to estimate individual ages-at-death for Balkan populations utilizing dental wear. Dental wear phases were scored following Smith's eight-phase ordinal scoring method and chart. To estimate age, probability density functions for the posterior distributions of age for each tooth phase are calculated. Transition analysis was utilized to generate a mean age-of-transition from one dental wear phase to the next. The age estimates are based on the calculated age distribution from the GM hazard analysis and the ages-of-transition. To estimate the age-at-death for an individual, the highest posterior density region for each phase is calculated. By using a Bayesian statistical approach to estimate age, the population's age distribution is taken into account. Therefore, the age estimates are reliable for the Balkan populations, regardless of population or sex differences. The results showed that a vast amount of interpersonal variation in dental wear exists within the current sample and that this method may be most useful for classifying unknown individuals into broad age cohorts rather than small age ranges. 相似文献

While victims of racially motivated violence may be identified through observation of morphological features, those targeted because of their ethnic, religious, or national identity are not easily recognized. This study examines how perpetrators of genocide recognize their victims. Court documents, including indictments, witness statements, and testimony from the International Criminal Tribunals for Rwanda and the former Yugoslavia (FY) detail the interactions between victim and assailant. A total of 6012 decedents were included in the study; only 20.8% had been positively identified. Variables influencing victim selection in Rwanda included location, segregation, incitement, and prior relationship, while significant factors in FY were segregation, location, age/gender, and social data. Additional contributing factors in both countries included self-identification, victim behavior, linguistic or clothing evidence, and morphological features. Understanding the system of recognition used by perpetrators aids investigators tasked with establishing victim identity in such prosecutions. 相似文献

The 608-bp hypervariable region 1 (HV1) sequences from 36 local dogs were analyzed to characterize the population genetic structure of canid mitochondrial DNA (mtDNA). Sixteen haplotypes were identified. A 417-bp segment of this sequence was compared with GenBank sequences from a geographically representative sample of 201 dogs, two coyotes, and two wolves. Sixty-six haplotypes were identified including 62 found only in domestic dogs. Fourteen of these correspond to the 16 local haplotypes and were among the most frequent haplotypes. The local sample was judged to be representative of the much broader geographic sample. No correlation was observed between local haplotypes and the owner's characterization of dog breed. A 60-bp variation "hotspot" within the canid HV1 was identified as a potentially valuable molecular tool, particularly for assaying limited or degraded DNA samples. 相似文献

This article reports on an exploratory study of ethical reasoning among public administrators in Russia. Survey interviews and focus group follow-ups with civil servants participating in graduate training programs at the Russian Academy of Public Service provide information about their preferred mode of ethical reasoning; the demographic, attitudinal, organizational, and professional factors associated with that reasoning; and the behavioral choices implied. Using a sample of 113 public officials who represent a broad spectrum of regions in Russia, this study assesses moral reasoning, examines variables associated with alternative models, and compares these responses with findings from studies conducted in Poland and the United States. Based on this exploratory study, we suggest implications for theory, research, and practice. 相似文献

This article reports the findings of a legislative survey conducted to determine the legal status of parent education in the United States. Specifically, this survey reveals that since 1994. the number of states that enacted legislation authorizing or mandating attendance at parent education programs has more than quadrupled. The article features a state-by-state analysis of the various legal models currently in effect, including the source of authority, attendence model, and legal circumstances giving rise to participation. A capsule summary describing specific characteristics of the governing law of each state is also provided for reference. 相似文献
