Several ink dating methods based on solvents analysis using gas chromatography/mass spectrometry (GC/MS) were proposed in the last decades. These methods follow the drying of solvents from ballpoint pen inks on paper and seem very promising. However, several questions arose over the last few years among questioned documents examiners regarding the transparency and reproducibility of the proposed techniques. These questions should be carefully studied for accurate and ethical application of this methodology in casework. Inspired by a real investigation involving ink dating, the present paper discusses this particular issue throughout four main topics: aging processes, dating methods, validation procedures and data interpretation. This work presents a wide picture of the ink dating field, warns about potential shortcomings and also proposes some solutions to avoid reporting errors in court.  相似文献

This study examined the prevalence of mental health and substance abuse disorders and service utilization among a racially and ethnically diverse group of foster youth. Self-report data on symptoms and service receipt were used to identify whether groups of adolescents defined by their race and ethnicity were equally likely to receive services given the presence of a mental health or substance use disorder. Study findings showed that Caucasians are more likely to receive mental health services than African Americans. Race was not a significant predictor of accessing substance abuse services. Hispanic ethnicity was not a predictor of receipt of mental health or substance abuse treatment services. Implications for future research, practice, and policy are discussed.  相似文献

Article 26.1 of the Cartagena Protocol on Biosafety left open the possibility for member countries to include in their biosafety regulatory processes the assessment of socio‐economic considerations. Countries may also decide to include such assessments as part of their national legislation or regulations for the approval and deliberate release into the environment of genetically engineered technologies. Countries are debating if and how to implement assessment of socio‐economic considerations. This paper contributes to the ongoing policy dialogue by discussing issues related to socio‐economic assessment including scope, timing, inclusion modalities, methods, decision‐making rules and standards, and the integration of socio‐economic assessments in biosafety and/or biotechnology approval processes. This paper also discusses the implications of such inclusion for technology flows and public and private sector R&D. If inclusion is not done properly, it may negatively impact technology flows especially from the public sector and render an unworkable biosafety system.  相似文献

New Public Management (NPM) recently has been compared and contrasted with public governance (PG) to illustrate shifts in conceptions of public administrations and in reform agendas. The authors develop measures to capture the relevance of NPM and PG in textual discourse and investigate the extent to which they have entered the political debate. Content analysis of electoral programs for the 2005 Italian regional elections reveals that even in this legalistic country, considerable attention was paid to both NPM and PG issues. An important explanatory variable in preference for NPM or PG is party ideology, highlighting often‐ignored within‐country dynamics. Furthermore, the authors show how a methodological approach adapted from mainly political science and business research can be exploited in the field of public administration.  相似文献

The purpose of this study is to clarify the chronology of different stages of dental development, according to Demirjian, in a sample of Spanish children, which will enable us to build a database that will be used as a reference in regard to the dental development of individuals of our socio-geographic environment. In the same studied sample, a calculation of the dental age according to Demirjian was carried out. This study was conducted in a final sample consisting of 1010 orthopantograms, corresponding to Spanish children (485 boys and 525 girls) ages 2-16. Comparing the age of onset of the different stages among the children, evidence was found that girls had an earlier general development than boys. These differences were only statistically significant in teeth and concrete stages. The canine teeth revealed greater gender dimorphism, with significant differences in all stages compared with the upper canines. The method proposed by Demirjian for dental age calculation resulted in a significant overestimation of dental age in relation to the chronological age in boys (average of 0.87 years) and girls (average of 0.55 years). Data from this study may be used as reference for dental maturity, as well as a standard for estimating age in Spanish children.  相似文献

I congratulate the Chinese Association for International Understanding for all it has been able to accomplish-during its 30 years of public diplomacy-in its mission to Let the world understand China, and let China understand the world.  相似文献
