A Moderated Mediation Model: Racial Discrimination,Coping Strategies,and Racial Identity Among Black Adolescents

This study examined a moderated mediation model among 314 Black adolescents aged 13–18. The model included general coping strategies (e.g., active, distracting, avoidant, and support‐seeking strategies) as mediators and racial identity dimensions (racial centrality, private regard, public regard, minority, assimilationist, and humanist ideologies) as moderators of the relation between perceived racial discrimination and depressive symptoms. Moderated mediation examined if the relation between perceived racial discrimination and depressive symptoms varied by the mediators and moderators. Results revealed that avoidant coping strategies mediated the relation between perceptions of racial discrimination and depressive symptoms. The results indicated that avoidant coping strategies mediated the relation between perceived racial discrimination and depressive symptoms among youth with high levels of the minority/oppressive ideology.     

Jakob Leupold's Imaginary Automatic Anamorphic Devices of 1713

In 1713, the scientific instrument-maker Jakob Leupold published designs for three machines were the first attempt to design machinery with internal moving parts that replaced human agency in creating original images. This paper first analyzes his text and engravings in order to explain how he proposed to do this, given contemporary materials and command of physical forces. Next, it characterizes the devices as a transition from concepts of incision to concepts of mirroring, taken as models of the history of mechanical reproduction. And finally, Leupold’s replacement of the sighting grid with differential gears points to a set of problems appearing in contemporary philosophy represented in Rococo artistic production of this period as well. Taking the proposed devices in context, they help to theorize the complex notions of creative activity in Rococo visual culture. Taken as an episode in the history of communications, they instance the development of conceptions of personhood and of physical forces at stake in the invention of automated media.     

The Inter-relationship of Science and Religion: A typology of engagement

This study explores whether the religious background of students affects their opinions about and attitudes to engaging with scientific explanations of the origins of the universe and of life. The study took place in four English secondary schools representing three different contexts (Christian faith-based; non-faith with majority Muslim catchment; and non-faith, mixed catchment). It comprised questionnaires and focus groups with over 200 students aged 14–16, supplemented by teacher interviews. The analysis approach was informed by grounded theory and resulted in the development of an engagement typology, which has been set in the context of the cross-cultural border crossing literature. It divides students into categories depending on both the nature and amount of engagement they were prepared to have with the relationship between science and religion. The model takes into account where students sit on four dimensions. These assess whether a student's preferred knowledge base is belief-based or fact-based; their tolerance of uncertainty (do they have a need for resolution?); their open mindedness (are they unquestioning or inquiring?); and whether they conceptualise science and religion as being in conflict or harmony. Many Muslim students resisted engagement because of conflicting religious beliefs. Teachers did not always appreciate the extent to which this topic troubled some students who needed help to accommodate clashes between science and their religious beliefs. It is suggested that increased appreciation of the complexity represented by their students can guide a teacher towards an appropriate approach when covering potentially sensitive topics such as the theory of evolution.     

Students' Visualization of Metallic Bonding and the Malleability of Metals

This study investigated the mental representations of metallic bonding and the malleability of metals held by three male students aged 14–15 (Year 10) who were attending a Hong Kong school. One student was selected by their chemistry teacher as representing each of the highest, the medium, and the lowest level of attainment in chemistry in a school that admitted students of average general attainment. The students were interviewed and their understandings probed through their provision of drawings and their interpretation of the diagrams that had been previously used by their teacher. Dual coding theory was used to interpret the relative significance of visual and verbal input and the interaction between the two for their understanding. There was evidence that students relied on verbal recall in providing their initial understandings and showed an appreciation of the nature of the structural components of the electron-sea model of metallic bonding. However, they varied in terms of their appreciation of the electrostatic force which was responsible for the malleability of metals. The study suggests that a clearer understanding of the electrostatic force involved can be attained when students experience visual and verbal representations simultaneously, a conclusion supported by dual coding theory. Principles for good practice in using diagrams in teaching are discussed.

A bibliometric analysis of academic publication and NIH funding

Academic productivity and research funding have been hot topics in biomedical research. While publications and their citations are popular indicators of academic productivity, there has been no rigorous way to quantify co-authors’ relative contributions. This has seriously compromised quantitative studies on the relationship between academic productivity and research funding. Here we apply an axiomatic approach and associated bibliometric measures to revisit a recent study by Ginther et al. (Ginther et al., 2011a, Ginther et al., 2011b) in which the probability of receiving a U.S. National Institutes of Health (NIH) R01 award was analyzed with respect to the applicant's race/ethnicity. Our results provide new insight and suggest that there is no significant racial bias in the NIH review process, in contrast to the conclusion from the study by D. K. Ginther et al. Our axiomatic approach has a potential to be widely used for scientific assessment and management.     

Enigmas in School Science: students’ conceptions for scientifically associated words

Master's students were involved in the design, and later the administration, of a questionnaire for 500 junior secondary students in Botswana and Lesotho, to buildup a picture of student perceptions of science and technology. Responses to mainly open‐ended questions were categorised according to key phrases mentioned by the students. There was some confusion over the differences between science and technology, but they were overwhelmingly perceived as subjects appropriate to both sexes. Science and technology were seen in broad socio‐economic terms, enabling people to cope in the modern world, gain employment in both the formal and informal sectors, and contribute towards national development. Although science and technology were judged to have enhanced the quality of life, they had introduced conflicts into traditional beliefs and cultures, in part as a result of increasing female emancipation. The attitudes of the students towards the two subjects, and to the impact they have had on everyday life, were congruent with the philosophical aims of the science and technology syllabuses of both countries and with global initiatives such as Project 2000 +.
