Changes in Teachers’ Involvement Versus Rejection and Links with Academic Motivation During the First Year of Secondary Education: A Multilevel Growth Curve Analysis

Research consistently shows that the learning environment plays an important role for early adolescents’ learning and outcomes and suggests that good teacher–student relationships can serve as a protective factor for maintaining young adolescents’ interest and active engagement in learning. However, less is known about the dynamic nature of teacher–student relationships and how they link with academic motivation development. Furthermore, little is known about the nature and the effects of teacher–student relationships in a cross-national context. The present study investigated changes in two components of teacher–student relationships (teachers’ involvement vs. rejection) and examined links with students’ academic motivation during the first grade of secondary school. Ten Dutch and ten Indonesian teachers (65 % female) from 24 classes were videoed 12 times across the school year, and four videos for each class were selected randomly and coded on teachers’ involvement versus rejection. A total of 713 students (52 % girls) completed four-wave measures of their academic motivation after each video observation. Multilevel growth curve modeling revealed that the teacher’s involvement changed in a curvilinear way and decreased across the first year of secondary education, while changes in the teacher’s rejection did not follow a linear time function. Academic motivation changed in an undesirable way: controlled motivation increased, while autonomous motivation decreased over time. Teachers’ involvement had a unique contribution in preventing high levels of controlled motivation in both countries. Findings suggest that teacher–student relationships (teachers’ involvement) play an essential role in early adolescents’ motivation regardless of the nations and should be a priority for schools.     

“Use words. Not your body”: The hunger that has no name

This essay examines the competing readings of food refusal that emerged from a student hunger strike held at Columbia University in fall 2007. The invisibility of the act of food refusal forces hunger strikers to adopt performance strategies that make their (non)action visible as protest. To make the politics of their food refusal legible, advocates for the hunger strike promoted their actions as part of a 40 year tradition of student protest. However, that same invisibility allowed the protest's detractors to deride the hunger strikers as anorexic. At the center of the protest and the commentary about it was a wasting female body that confused for spectators the line between the political and the pathological. Attention to this body raises questions of how community is created and disciplined through performative acts, how easily female protest is evacuated of political meaning and the uneasy role of whiteness in popular attention to anorexia.     

Maquiladora Mortality: Manufacturing Plant Closure in Mexico

Manufacturing plant closure has been the subject of much national concern, and an extensive literature principally focused on the developed world. This study extends the findings on plant closure with an analysis of export-oriented manufacturers (maquiladoras) in Mexico, 1996–2006. The foci of this research are hypothesised variables of maquiladora closure: product manufactured (value-added), size of plant, plant location, and size of urban place. The results of a logistical regression model indicate that plant size and value-added are highly probable determinants of plant closure; large, high value-added product maquiladoras have low rates of plant closure. Maquiladoras manufacturing low value-added products have high rates of closure; however, these manufacturers also have significant numbers of surviving plants. This suggests that multiple manufacturing platforms are viable among Mexico’s export-oriented industry. The findings also suggest that much plant closure is a result of exogenous factors,exiting plants in a global search for cheap labour. Mexico, however, has a geographic comparative advantage that, for many maquiladoras, trumps wages in more distant locations.     

Are Charitable Giving and Religious Attendance Complements or Substitutes? The Role of Measurement Error

Government policies sometimes cause unintended consequences for other potentially desirable behaviors. One such policy is the charitable tax deduction, which encourages charitable giving by allowing individuals to deduct giving from taxable income. Whether charitable giving and other desirable behaviors are complements or substitutes affect the welfare benefit of the deduction—complements increase the benefit, while substitutes decrease the benefit. This paper focuses on the effect of the deduction on one behavior in particular: religious attendance. Using data from the Independent Sector Survey of Giving and Volunteering, I estimate a tax price elasticity for religious attendance of ?0.4, which implies that charitable giving and religious attendance are complements. I resolve the difference between my estimate and a recent estimate by W. S. Gruber (2004) that implies charitable giving and religious attendance are substitutes. While Gruber imputes itemization status, an important factor in calculating tax incentives, I use survey‐reported itemization status. This imputation creates a large amount of non‐classical measurement error. I show that the measurement error is responsible for the disparate results: If I also impute itemization status, I obtain similar results as Gruber.     

Liberal Nationalism and Responsible Citizenship in South Korea

This essay explores how South Koreans have creatively acculturated the meaning of citizenship using Confucianism-originated familial affectionate sentiments (ch?ng), while resisting a liberal individualistic conception of citizenship, by investigating contemporary nationalist politics in South Korea. Its central claim is that the ch?ng-induced politico-cultural practice of collective moral responsibility (uri-responsibility), which transcends the binary of individualism and collectivism and of liberalism and nationalism, represents the essence of Korean national citizenship. In other words, this essay attempts to make a Korean case of “liberal nationalism” in its post-Confucian context.     

The future of coastal development in the Yellow Sea Rimlands

With its strategic location in East Asia, the Yellow Sea Rim is becoming an important economic region, where the socialist economies of China and North Korea and the market economies of Japan and South Korea interact and exchange for their mutual benefit. In light of the recent rapprochement among Northeast Asian countries, the article describes the emerging pattern of development in the Yellow Sea Rim. It assesses the potential gains of opening up the region by assuming a complete or partial removal of political barriers. Anticipating the future of cooperative regional development in the Yellow Sea Rimlands, the article discusses regional strategies and key issues involved in cooperation, in particular between China and South Korea.     

HIV study among pregnant Aboriginal women raises concerns

Extension of the color suite available for chemical enhancement of fingerprints in blood

The use of ortho- and para-phenylenediamine (OPD & PPD respectively) for the enhancement of fingerprints in blood has been investigated. Optimal pH conditions and H2O2 concentrations have been determined using UV/Vis spectroscopy. Both OPD and PPD are effective and less hazardous alternatives to the presently used 3,3'-diaminobenzidine (DAB) for the development of blood fingerprints, especially on porous surfaces. The orange color of OPD and the purple color of PPD offer alternative colors to the brown color of DAB and the light green color of ABTS for standing out against particular backgrounds. Both OPD and PPD can be used after ninhydrin treatment, but the reverse is not the case.     

Age estimation by occlusal tooth wear

The purpose of the present investigation was to test the accuracy of a new scoring system in recording tooth wear for age estimation. The material consisted of dental stone casts of 383 volunteers who had sound premolars and molars with normal occlusion. The degree of occlusal wear for all premolar and molar teeth was scored with the new system. The high intra- and inter-examiner concordances showed that the new score system was very reliable. The degree of tooth wear showed a significant positive correlation with age in each and every examined tooth of both males and females. Tooth wear scores of males were higher than those of females. Calculating tables for age estimation were designed and the accuracy of age estimation was obtained with the General Linear Models procedures. Our system could provide estimation of an individual's age within +/-3 years in 42.4% of males and 49.4% of females, within +/-5 years in 61.8% of males and 63.3% of females. When the subjects were divided into two age groups and data were re-treated, the accuracy of age estimation was increased. Collectively, it was shown that our new system for scoring tooth wear is a reliable and accurate method for age estimation.
