Contemporary, population‐specific ossification timings of the cranium are lacking in current literature due to challenges in obtaining large repositories of documented subadult material, forcing Australian practitioners to rely on North American, arguably antiquated reference standards for age estimation. This study assessed the temporal pattern of ossification of the cranium and provides recalibrated probabilistic information for age estimation of modern Australian children. Fusion status of the occipital and frontal bones, atlas, and axis was scored using a modified two‐ to four‐tier system from cranial/cervical DICOM datasets of 585 children aged birth to 10 years. Transition analysis was applied to elucidate maximum‐likelihood estimates between consecutive fusion stages, in conjunction with Bayesian statistics to calculate credible intervals for age estimation. Results demonstrate significant sex differences in skeletal maturation (p < 0.05) and earlier timings in comparison with major literary sources, underscoring the requisite of updated standards for age estimation of modern individuals. 相似文献

The authors are exploring degradation patterns of latent fingermarks over time which can be quantitatively determined in a predictable manner by visual means. Several physical degradation parameters for assessing this hypothesis are evaluated. This article analyzes the parameter “minutiae count” as a function of time. Experiment variables included were secretion type (sebaceous‐rich and eccrine‐rich), substrate (glass and plastic), and exposure to light (dark, shade, and direct light). Depositions were sequentially visualized with Titanium Dioxide powder over a period of 6 months, photographed, and number of minutiae recorded. Results revealed a significant decrease of minutiae for eccrine‐rich marks on glass but insignificant for sebaceous‐rich marks on the same surface. However, significant degradation was observed for both types of secretions on plastic. The authors conclude that the distinctive prevalence of minutiae changes over time indicates with a high degree of certainty the hypothesis is valid and deserves additional exploration. 相似文献

During the details stage of multilateral economic talks, agreements are usually negotiated using a combination of two methods ‐ compromise on individual issues and tit‐for‐tat exchanges. This article identifies the circumstances in which the the US, EEC and British delegations employed these traditional diplomatic techniques, and assesses the effectiveness of these techniques in forging agreement in the details stage of the Kennedy Round, Providing a detailed account of these talks, the article demonstrates that the negotiating techniques of the American delegation were far more flexible than those of the European and British delegations and that this flexibility was vital to the successful completion of the talks. The article concludes that differences in negotiating technique are best explained by a combination of two factors ‐ the contrasting decision making structures of each negotiating team and the international political context of the negotiations. 相似文献

The recent introduction of the Psychopathy Checklist-Revised (PCL-R) into the sentencing phase of capital murder trials has heightened concerns about the potentially prejudicial impact of such information on jurors, who might give disproportionate weight to this diagnosis when determining whether a defendant is a “continuing threat to society”. To investigate this issue, 238 undergraduates read a case summary based on US v. Barnette ( ), in which prosecution testimony was presented regarding the presence of a mental disorder (psychopathy, psychosis, or no disorder). Compared to the “no disorder” condition, participants rated psychopathic defendants as more likely to be violent in the future, even though testimony related to level of risk (high or low) was held constant. The difference in perceived dangerousness across the psychopathy and no disorder groups was particularly pronounced when the experts described the defendant as being at low risk. A similar pattern of effects was noted for the psychosis condition, suggesting that the impact of mental disorder testimony on perceptions of dangerousness may not necessarily be specific to the PCL-R. 相似文献

An unknown, viscous, opaque, white liquid with a strong, unpleasant odor was submitted with a request for identification. It was analyzed using infrared (IR) spectroscopy, gas chromatography–mass spectrometry, and X‐ray fluorescence spectroscopy. It was found to contain glycerin as well as another compound. IR and mass spectral data were readily obtained for this second component, but it was not easily identified as common instrument libraries had no matching spectra. After an extensive literature search, the unknown compound was identified as spiromesifen, a recently introduced pesticide. The IR spectrum and electron impact mass spectrum of spiromesifen are presented here as these are not available in the published literature. This case report also provides useful approaches for searching for and identifying an unknown compound when it is not found in a laboratory's spectral libraries. 相似文献

Batterers intervention programs (BIPs) constitute a primary intervention for perpetrators of intimate partner violence (IPV). There is little understanding as to what elements are necessary for a good intervention program. We conducted 36 individual semi-structured interviews with professionals working with BIPs. Our results yielded three thematic categories: (1) optimal BIP structure—group size and program duration should foster change and interaction, (2) facilitator characteristics—co-facilitation is ideal, and facilitators should have IPV training, and (3) program approaches–programs should challenge their clients on their behavior, promote an environment of safety and openness, and strive to adapt to clients. 相似文献
