Identification of unknown living or deceased persons using dental treatment records is an established forensic technique. However, some cases remain unidentified, especially when antemortem dental records are not available for comparison to postmortem dental records. Cytological smears have been previously reported to be potential sources of DNA reference samples which can be compared to DNA recovered from found human remains. The case described here involves an adult skeleton which exhibited extensive, complex dental restorative treatment. A putative identification of the found skeleton as a missing woman was established using circumstantial evidence found at the scene. However, it became important to establish a positive identification using reliable scientific methods. When it was discovered that antemortem dental records were not available because the treatment was completed in another country and the treating dentist could not be found, cytological smears stained with Papanicolaou (PAP) stain obtained from the putative decedent's medical records were used as a reference DNA sample. DNA was recovered from the teeth of the skeleton using cryogenic grinding. Comparison of the genotypes resulted in the conclusion that the DNA originated from the same source. The use of PAP smears in this way is seen as a valuable resource in cases where positive identification using traditional dental and medical records is not possible. 相似文献

Attitudes toward racialized and redistributive policies like welfare are often thought of as a function of both principled ideological positions and the underlying racial attitudes a person holds. Kinder and Sanders (1996) look at racial resentment as one explanation, while Sniderman and his colleagues look to principled conservatism and authoritarianism as viable alternatives, claiming that racial resentment is merely proxying a legitimate race‐neutral commitment to equality of opportunity. This article engages this debate through an experimental design which tests whether “hard work” is rewarded in a color‐blind manner. The experimental design also affords scholars the opportunity to separate the effects of the two components of racial resentment: principled values and racial animus. The results show that American norms and implicit racism serve to uniquely privilege whites in a variety of ways. 相似文献

As one of the initial, and arguably most devastated, casualties of the Second World War, Poland's restoration as a free and independent state was seen as a test case for the viable continuation of the victorious Grand Alliance. Yet seemingly irreconcilable differences between the Western powers and the Soviet Union over intricate territorial and political issues (with the Polish state and people caught firmly in the middle) would signal the end of the working alliance. The US collectively struggled to come to terms with this "Polish problem"– its government failing to deliver to the Poles on those democratic principles enshrined within the Atlantic Charter, and its people finding the very ideals for which they had gone to war compromised. While reflecting the unique complexities of this particular dilemma, American officialsrsquo; perceptions of the conundrum over Poland bear a ringing familiarity to future East European developments and certainly set the tone for the ensuing West-Soviet impasse there. Indeed, this author would not be alone in suggesting that the superpower struggle over Poland at the close of World War II was itself the very genesis of the Cold War conflict. 相似文献

Tests that infer the ancestral origin of a DNA sample have considerable potential in the development of forensic tools that can help to guide crime investigation. We have developed a single-tube 34-plex SNP assay for the assignment of ancestral origin by choosing ancestry-informative markers (AIMs) exhibiting highly contrasting allele frequency distributions between the three major population-groups. To predict ancestral origin from the profiles obtained, a classification algorithm was developed based on maximum likelihood. Sampling of two populations each from African, European and East Asian groups provided training sets for the algorithm and this was tested using the CEPH Human Genome Diversity Panel. We detected negligible theoretical and practical error for assignments to one of the three groups analyzed with consistently high classification probabilities, even when using reduced subsets of SNPs. This study shows that by choosing SNPs exhibiting marked allele frequency differences between population-groups a practical forensic test for assigning the most likely ancestry can be achieved from a single multiplexed assay. 相似文献

Recent interest in the construct of motivation to change among male perpetrators of intimate partner violence (IPV) has led
to development of two self-report measures of this construct: the University of Rhode Island Change Assessment for Domestic
Violence (URICA-DV; Levesque et al. 2000) and the Safe at Home Inventory (SAH; Begun et al. 2003). We examined the internal
structure of these instruments using confirmatory and exploratory factor analyses in a sample of 199 male IPV perpetrators
waiting to begin court-mandated batterer intervention programs. Results indicated that the scales had adequate internal consistency.
However, using confirmatory factor analyses, the hypothesized structural models of each instrument fit the data poorly. Subsequent
models suggested by a series of exploratory factor analyses failed to improve model fit substantially for both scales. For
the URICA-DV, a 3-factor model including items from the Precontemplation, Contemplation, and Action subscales fit the data
adequately. No acceptable model fit could be found for the SAH. Intercorrelations among similar subscales across the two inventories
suggested only a modest degree of intercorrelation (r’s = 0.16–0.52), and a factor structure more dependent on scale of origin than item latent content, suggesting that the scales
assess different facets of the readiness to change construct. These results suggest that before the stages of change construct
can be fully applied to the IPV area, more research and evaluation are needed on how to accurately assess abuser readiness
to change. 相似文献

When this Journal decided to run a special issue on IP in theAsia-Pacific region, it was following the conventional wisdomof the profession and the marketplace. For many years, the conceptof the Asia-Pacific sold conferences and printed publications.And it was on this assumption that JIPLP based its decisionto give over its March issue for coverage of that zone.
