Emotional arousal of beginning physics teachers during extended experimental investigations

Teachers often have difficulty implementing inquiry‐based activities, leading to the arousal of negative emotions. In this multicase study of beginning physics teachers in Australia, we were interested in the extent to which their expectations were realized and how their classroom experiences while implementing extended experimental investigations (EEIs) produced emotional states that mediated their teaching practices. Against rhetoric of fear expressed by their senior colleagues, three of the four teachers were surprised by the positive outcomes from their supervision of EEIs for the first time. Two of these teachers experienced high intensity positive emotions in response to their students' success. When student actions/outcomes did not meet their teachers' expectations, frustration, anger, and disappointment were experienced by the teachers, as predicted by a sociological theory of human emotions (Turner, J. H. (2007). Human emotions: A sociological theory. London, England: Routledge). Over the course of the EEI projects, the teachers' practices changed along with their emotional states and their students' achievements. We account for similarities and differences in the teachers' emotional experiences in terms of context, prior experience, and expectations. The findings from this study provide insights into effective supervision practices that can be used to inform new and experienced teachers alike. © 2012 Wiley Periodicals, Inc.

A tool for changing the world: possibilities of cultural‐historical activity theory to reinvigorate science education

Cultural‐historical activity theory, an outcrop of socio‐psychological approaches toward human development, has enjoyed tremendous growth over the past two decades but has yet to be appropriated into science education to any large extent. In part, the difficulties Western scholars have had in adopting this framework arise from its ontology, which is materialist dialectical and, hence, does not allow easy absorption into non‐dialectical (classical logical) thinking underlying much of Western scholarship. Cultural‐historical activity theory has tremendous potential because it sublates traditional dichotomies in everyday teaching‐learning situations including individual/collective, body/mind, intra‐/inter‐psychological, cognitive/emotive and psychological/sociological. In this contribution, we not only review the existing literature that uses or develops this non‐dualistic approach, but also articulate an intelligible explication of the theory that is more accessible to Western scholars and describe possible future curriculum work and research in science education as an expression of the fruitfulness of the theory.     

The effectiveness of subsidies revisited: Accounting for wage and employment effects in business R&D

The present paper investigates the effectiveness of public subsidies on business enterprise research in a panel of OECD countries. We contribute to the literature by explicitly distinguishing between the effects of a subsidy on R&D employment and expenditure, thereby accounting for a potential increase in scientists’ wages. We employ instrumental variable regressions to address endogeneity problems of the subsidization. The results indicate that subsidies are effective in generating additional research expenditure. Expenditure for business research increases by roughly 20% more than employment. We take this as evidence that subsidies may raise scientists’ wages given standard production functions.     

Transgender and Gender-Nonconforming Student Experiences in Christian Higher Education: A Qualitative Exploration

Religion and spirituality are important in the lives of many transgender and gender-nonconforming (TGNC) individuals. Although TGNC students can make unique contributions to Christian colleges and universities (CCUs), many individuals who identify as both religious and TGNC report rejection from nonaffirming religious communities that view TGNC identities and expression as sinful or psychologically disordered. Additionally, previous research has suggested that TGNC college students experience disproportionately high rates of verbal and sexual harassment, threats, physical assault, and anti-TGNC messaging on college campuses. In order to better understand the experiences of TGNC students who attended nonaffirming CCUs, semistructured interviews were conducted with seven TGNC students and alumni regarding their gender identity, religion, spirituality, campus experiences, and perceptions of campus climate. Data analysis was completed using guidelines consistent with Interpretative Phenomenological Analysis (Shaw, 2010). Findings revealed four major themes: (a) invisibility of TGNC individuals and identities on campus, (b) rejection within the college environment, (c) ambivalence and psychological conflict about integrating religion, spirituality, and gender identity, and (d) resilience and the importance of campus support systems. Recommendations for creating greater inclusion of TGNC students on CCU campuses are presented. This study also explores clinical considerations for mental health professionals and student services personnel employed at CCUs.     

Human capital background and the educational attainment of second-generation immigrants in France

In this paper, we study the impact of parental human capital background on ethnic educational gaps between second-generation immigrants using a large data set conducted in France in 2003. Estimates from censored random effect ordered Probit regressions show that the skills of immigrants explain in the most part, the ethnic educational gap between their children. Fluency in French and the length of their parents’ stay in France also matter. The impact of the immigrants’ education on the educational attainment of their children further depends on their country of origin, their place of schooling, and their proficiency in French.     

Drawing Subway Maps: A?Survey

This paper deals with automating the drawing of subway maps. There are two features of schematic subway maps that make them different from drawings of other networks such as flow charts or organigrams. First, most schematic subway maps use not only horizontal and vertical lines, but also diagonals. This gives more flexibility in the layout process, but it also makes the problem provably hard. Second, a subway map represents a network whose components have geographic locations that are roughly known to the users of such a map. This knowledge must be respected during the search for a clear layout of the network. For the sake of visual clarity the underlying geography may be distorted, but it must not be given up, otherwise map users will be hopelessly confused. In this paper we first give a rather generally accepted list of rules that should be adhered to by a good subway map. Next we survey three recent methods for drawing subway maps, analyze their performance with respect to the above rules, and compare the resulting maps among each other and to official subway maps drawn by graphic designers. We then focus on one of the methods, which is based on mixed-integer linear programming, a widely-used global optimization technique. This method guarantees to find a drawing that fulfills a subset of the above-mentioned rules (if such a drawing exists) and optimizes a weighted sum of costs that correspond to the remaining rules. The method can draw even large subway networks such as the London Underground in an aesthetically pleasing manner, similar to maps made by professional graphic designers. If station labels are included in the optimization process, so far only medium-size networks can be drawn. Finally we give evidence why drawing good subway maps is difficult (even without labels).
