Microscopic Age Estimation from the Anterior Cortex of the Femur in Korean Adults*

Abstract: The purpose of this study was to develop age‐predicting equations from the anterior cortex of the femur of Korean adults. Seventy‐two femoral samples (44 male and 28 female) were obtained from Korean cadavers and used to develop the equations. The thin sections (<100‐μm thick) were prepared by manual grinding; the sections were not decalcified and were stained with Villanueva bone stain reagent. Analysis of covariance showed no significant differences in age‐adjusted histomorphological variables between sexes. In stepwise regression analysis, osteon population density, average osteon area, and the most anterior cortical width were selected for an age‐predicting equation which produced a high regression correlation (R² = 0.789). The average Haversian canal area was not significantly related to age for any specimen.     

Attitudes of Omani early childhood preservice teachers toward bilingual early childhood education: Benefits,challenges, and solutions

Compared to earlier times, many Omani parents have become more enthusiastic about bilingual education for their young children. To fully understand and improve early bilingual education, it is critical to start with an inquiry into prospective practitioners' attitudes toward bilingualism in early education as they are the ones who will work in bilingual education programs. Therefore, this research investigated the attitudes of early childhood pre-service teachers in Oman, toward bilingual education during children's early years. The data were gathered using qualitative survey methods with a focus group and analyzed using thematic analysis. Hence, essential themes and sub-themes were extracted from the data and an exhaustive analysis of pre-service teachers' attitudes toward bilingual education in the early years was conducted. The findings revealed that participants tend to favor such programs. Although they believe there are a few challenges in the field, they reported possible solutions that are presented in this study. Implications are discussed and recommendations are made.     

A CASE OF PARTIAL CONVERGENCE: THE EUROPEANIZATION OF CENTRAL GOVERNMENT IN CENTRAL AND EASTERN EUROPE

This article compares the Europeanization of central government in four Central and Eastern European countries (CEECs): Estonia, Latvia, Poland, and Slovakia. Using a large N survey of ministerial civil servants, it finds that the Europeanization of central government is characterized by partial convergence. The scope of Europeanization is large and similar among CEECs, reaching widely and deeply into government ministries. Moreover, patterns of Europeanization are similar among CEECs: the same ministries form the ‘inner core’ and ‘outer circle’ of Europeanized ministries; only a small proportion of civil servants work full‐time on EU issues and routinely engage in activities that ‘project’ national policies at EU level. Compared to old member states, patterns of Europeanization show signs of convergence, while the scope of Europeanization is larger in CEECs.     

“We don’t want to hear about discrimination”: Evidence slippage and evidence invention in the politics of foreign credential recognition in Canada

This article investigates how Canadian politicians engaged with evidence on foreign credential recognition in 2009. We find that some evidence receives decreasing attention over time, that some politicians bring forward explanations that have nothing to do with the evidence, and that most politicians hold the same position before and after the process of evidence‐gathering. These findings cast doubt on the extent to which politicians use evidence to inform their position on immigration‐related issues, even when they explicitly solicit it.     

Constraining Executive Action: The Role of Legislator Professionalization in Latin America

What explains the failure of legislatures with strong constitutionally endowed powers to exert themselves over the executive in practice? We examine the role of legislator professionalization in strengthening the legislature's ability to constrain executive action, conceptualizing legislator professionalization as prior legislative experience and prior professional work experience. We argue that more professionalized legislators, through the skill and knowledge they bring to the policymaking process from prior experience, will be better equipped to challenge executive authority. In a sample of four Latin American countries from 1990 through 2010, we find that legislatures are more likely to curb executive decree issuance when individual legislators are strongly professionalized, controlling for constitutional powers and several other partisan and political factors. Our findings suggest that legislatures composed of more professionalized legislators can constrain executive action, especially in the context of a unified political opposition in the legislature.     

Presidential Approval and Public Security in Mexico's War on Crime

To fight criminal organizations effectively, governments require support from significant segments of society. Citizen support provides important leverage for executives, allowing them to continue their policies. Yet winning citizens' hearts and minds is not easy. Public security is a deeply complex issue. Responsibility is shared among different levels of government; information is highly mediated by mass media and individual acquaintances; and security has a strong effect on peoples' emotions, since it threatens to affect their most valuable assets—life and property. How do citizens translate their assessments of public security into presidential approval? To answer this question, this study develops explicit theoretical insights into the conditions under which different dimensions of public security affect presidential approval. The arguments are tested using Mexico as a case study.
