Age estimations were performed on 100 teeth according to the methods of Bang and Ramm (unsectioned and sectioned teeth), Miles, Johanson, and Dalitz, and in addition by visual examination of the unsectioned teeth. Mean error as well as standard and mean deviations were calculated. The method of Johanson was found to be slightly more reliable than the others. Visual estimation was also in some respects better than the other three methods. All methods resulted in the largest number of overestimates in teeth from persons below 40 years, from males, from the maxilla, and in teeth removed from corpses. Underestimates were predominant in teeth from persons above 50 years. 相似文献

Since 1951 a Danish-American defense agreement on Greenland has regulated US military activities there. The article gives a detailed empirical-theoretical analysis of the negotiation of the Agreement under five perspectives: bargaining power, agenda setting, negotiating positions, strategies and outcomes. An important parameter was the fact that negotiations took place in a cooperative setting with a long shadow of the future. This made for a skewed, though regular negotiation process with a give-and-take of positions, counter-positions and concessions. Negotiating strategies varied, with the US side concentrating on an "authority" strategy, while the Danes relied on a mixture of off-setting "moral" and "tied hands" strategies. Although the US got the best outcome, it was not a dictate, because the ground was leveled by the negotiations taking place as part of the build-up of a long-term security relationship and the fact that the United States was the demandeur vis-à-vis Denmark. 相似文献

Most criminogenic risk assessments are developed and empirically validated on samples of boys or samples comprised of mostly boys, and subsequently applied to girls. Using a sample of male (n = 1,267) and female (n = 453) probationers, the purpose of the current study was to examine the potentially differential performance of the Youth Level of Service/Case Management Inventory (YLS/CMI) and the instrument’s eight domains for female juvenile offenders. Findings revealed gender differences in the predictive validity of the YLS/CMI in which girls scored significantly higher on the risk assessment, but recidivated at significantly lower rates than boys two years following the administration of the assessment. The predictive validity of the instrument was impacted by these gender differences in which the YLS/CMI total score was a better predictor of recidivism for boys (area under the curve (AUC) = .623) than girls (AUC = .565). The only subscales that significantly predicted recidivism for girls were the family (AUC = .607) and personality (AUC = .572) domains, whereas all of the subscales significantly predicted recidivism for boys. Directions for future research as well as gender-responsive assessment, programming, and policy implications are discussed. 相似文献

Anterior teeth within the human dentition have a specific numerical rotation value. Bite marks show an array of angled indentations, abrasions, microlacerations, and contusions. These marks generally represent the incisal surfaces of the suspect's dentition reflecting the rotation values of the teeth in the dental arch. This study described a method for capturing and analyzing anterior dental rotations. The rotations of individual anterior teeth within the study population were categorized as common, uncommon, and very uncommon according to Allen's classification. In the absence of a large number of incisal patterns present in a bite mark, a single but heavily weighted tooth rotation could be of equal discriminatory potential to several common rotation values. No prevalence studies quantifying individual tooth rotations are available. The measurement of each individual tooth rotation together with its individual discrimination potential will enhance the evaluation of the concordant features observed in bite marks. 相似文献

This study examined microcrystals formed by silver with gamma-hydroxybutyric acid (GHB) and gamma-hydroxyvaleric acid (GHV), the five-carbon analog of GHB, in the presence of silver, copper, and lanthanide nitrates. Distinct microcrystals formed with silver (+1) and lanthanum (+3) ions but not with the copper (+2) ions. The crystals formed with GHB were distinctly different than those formed with GHV and in all cases, the drug microcrystals were easily distinguishable from reagent crystals. X-ray diffraction analysis provided definitive structure for the microcrystals. The morphological differences between the silver-GHB and silver-GHV crystals were characterized using simple measurements such as size and angles provided by image recognition software. The utility of the test for casework was demonstrated using spiked beverage samples. 相似文献

This article focuses on the need to move past First Amendment concerns to foster a meaningful debate about the licensing of public relations practitioners. Whether, and to what extent, public relations should be licensed is not the subject of this discussion. Instead, this article uses Aristotelian logic to dispute the spurious conclusion that any licensing scheme for public relations work and / or the individuals who perform it is unconstitutional on its face. Relying on First Amendment jurisprudence, the article demonstrates that some restraints on speech in the form of licensing are allowed, that not all public relations work involves protected speech or press, that there is a similarity to the constitutionally permitted licensing of certain speech‐related professions and that a hypothetical case can be constructed regarding those who could qualify as licensed public relations counsel. The article concludes that the First Amendment does not necessarily prevent licensing certain public relations practitioners. 相似文献
