Allelic frequencies of 15 short tandem repeats (STR) markers (CSF1PO, FGA, THO1, TPOX, VWA, D3S11358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, D19S433 and D2S1338) were determined using the AmpFl STR Identifiler PCR Amplification Kit in Puerto Rican American individuals (N=205) from Massachusetts. The FGA, D18S51 and D2S1338 loci had a high power of discrimination (PD) with values of 0.967, 0.965 and 0.961, respectively. Significant deviations from the Hardy-Weinberg (HW) equilibrium were not detected. An important genetic contribution of Caucasian European (76.4%) was detected in Puerto Rican Americans. However, comparative analysis between Puerto Rican American and other neighboring populations from United States mainly with African and Caucasian Americans, revealed significant differences in the distribution of STR markers. Our results are important for future comparative genetic studies of different American ethnic groups, in particular a cultural group called Hispanic-Americans and should be helpful for forensic and paternity testing. 相似文献

Color determination of soil evidence is often done by visual comparison to soil color charts. A handheld spectrophotometer was tested with representative materials for its suitability for forensic soil characterization. Instrumental colorimetry provides accurate colorimetry with ~10-fold better precision than a soil color chart. The minimum sample size for accurate color determination was between 0.02 and 0.04 mg of fine soil for the specific instrument tested. Reporting colors in the L*a*b* space permits quantification of ΔE00, a measure of perceptible color difference, could enable objective quantification of small color differences and thresholds for forensic soil comparisons. A ΔE00 greater than ~ 3.5 to 6 likely indicates disparate soil sources in a forensic comparison, in the absence of confounding factors like sample alteration. Despite the superior precision of instrumental colorimetry, this approach is inappropriate for samples which are mottled at an inseparable scale, attached to a substrate, or too small for instrumental measurement. 相似文献

In a recent Public Opinion Quarterly article “Is the Academy a Liberal Hegemony?,” John Zipp and Rudy Fenwick pit themselves against “right-wing activists and scholars,” citing our scholarship (Klein and Stern in Academic Questions 18(1): 40–52, 2005a; Klein and Western in Academic Questions 18(1): 53–65, 2005). Here, we analyze Zipp and Fenwick’s characterization of our research and find it faulty. We, then, turn to their self-identification “liberal vs. conservative” findings and show they concord with our analysis. If one feels that it is a problem that humanities and social science faculty at 4-year colleges and universities are vastly predominantly democratic voters, mostly with views that may called establishment-left, progressive, or status-quo oriented, then such concerns should not be allayed by Zipp and Fenwick’s article. We commence the article with a criticism of the “liberal versus conservative” framework because it is the source of much of the confusion surrounding controversies such as the one over the ideological profile of faculty. 相似文献

Much of existing assessment and instructional design strategies revolve around the use of learning objectives. Learning objectives are used by faculty, by instructional designers, by accreditors, by assessment offices, and by students. But even as the use of learning objectives becomes more widespread, the definition and purpose have remained unclear. Instructional designers argue that learning objectives exist to provide a focused mindset for students engaging in the content, while faculty often view learning objectives as an administrative requirement that has little impact on teaching or student performance. Existing research on the subject is primarily normative and/or qualitative in nature (Harden 2002; Torrance 2007). In this article, the researchers seek to use empirical evidence to examine the definitions, purpose, and impact of learning objectives on student performance. We find that there is no shared understanding of definitions and purpose, and using an experimental design, we find that learning objective wording and use in the classroom does not affect student performance. 相似文献

AbstractIn this article, I study the journey of the Finland-Swedish author Monika Fagerholm’s (b. 1961) novel The American Girl to the pages of O, The Oprah Magazine. This event, here called “Fagerholm goes Oprah”, offers an illustrative example of the global movements of literature today, and of the ongoing negotiation of relations between local and global, the Nordic countries and the USA, minor literature and the global market. The article describes the different phases of the transmission of this novel, studies the means by which a novel from a minor body of literature transgresses its geo-linguistic position and, in this specific case, demonstrates the role of gender. In this way, the novel not only creates fictive, transnational spaces for its female characters and readers, but it also enters and contributes to a network of female agents in widely different geographical and cultural contexts. The event “Fagerholm goes Oprah” is a sign of the ongoing globalization of the literary field, but its reception also reveals the presence of an opposing tendency: the continuing significance of localization in literary exchange. All in all, the novel and its reception illustrate the many strategies used to create a connection between two different cultures, and also display the importance of various cultural currents in the transmission of the novel, such as feminism and Nordic Noir. 相似文献

This paper provides new evidence on the determinants of entrepreneurship across countries. The paper investigates the relationship between the institutional setting, in terms of economic freedom, and entrepreneurship, measured by self-employment, in a panel data setting covering 23 OECD countries for the period 1972–2002. The measure of economic freedom includes five aspects: size of government, legal structure and security of property rights, access to sound money, freedom to trade internationally, and the regulation of credit, labour and business. The empirical findings show that a smaller government sector, better legal structure and security of property rights, as well as less regulation of credit, labour and business tend to increase entrepreneurship. 相似文献
