Inter-Parietal White Matter Development Predicts Numerical Performance in Young Children

In an effort to understand the role of interhemispheric transfer in numerical development, we investigated the relationship between children's developing knowledge of numbers and the integrity of their white matter connections between the cerebral hemispheres (the corpus callosum). We used diffusion tensor imaging (DTI) tractography analyses to test the link between the development of the corpus callosum and performance on symbolic and non-symbolic numerical judgment tasks. We were especially interested in the interhemispheric connections of parietal cortex in 6-year-old children, because regions of parietal cortex have been implicated in the development of numerical skills by several prior studies. Our results revealed significant structural differences between children and adults in the fibers of the corpus callosum connecting the left and right parietal lobes. Importantly, these structural differences were predictive of individual differences among children in performance on numerical judgment tasks: children with poor numerical performance relative to their peers exhibited reduced white matter coherence in the fibers passing through the isthmus of the corpus callosum, which connects the parietal hemispheres.     

Relationships between the use of test results and US students’ academic performance

In this study, we examined relationships between the use of test results and US students’ math, reading, and science performance in the Programme for International Student Assessment (PISA) 2009. Based on a literature review, we hypothesized that the 16 items in the PISA school questionnaire, which are related to the use of test results, can be categorized according to 4 factors. We validated this hypothesized factor structure using a confirmatory factor analysis and then obtained composite scores for each factor. As revealed by a multilevel analysis, when student and school demographic variables were controlled for, using test results to hold schools accountable to authority and the public was significantly positively related to students’ performance across all 3 subjects. No statistically significant relationship, however, was detected between students’ performance and the following uses of test scores: informing parents of their children’s performance, providing information for instructional purposes, and evaluating teachers and principals.     

How Will They Understand if We Don’t Teach Them? The Status of Criminal Justice Education on Gay and Lesbian Issues

Inclusion of race and gender in criminal justice education has, to some degree, been prompted as a result of perceived bias by criminal justice system professionals. Utilizing the race and gender experience as a template, interactions between the gay, lesbian, bisexual and transgendered (GLBT) community and the criminal justice system are explored. This study surveyed criminal justice undergraduate degree programs to ascertain course content on gay and lesbian issues. Results indicate that an extremely small number of programs have such a course or alternatively incorporate GLBT issues within existing race and gender courses. Implications for criminal justice education are discussed.     

Scientific Education,Girls’ Schools and the Industrial Fund: a research note

During the 1950s a group of major companies launched the Industrial Fund for the Advancement of Scientific Education in Schools to build and equip laboratories in independent and direct grant schools. The Industrial Fund remains as one of the most impressive industrial initiatives in school education. It is sometimes criticised for either neglect or parsimony towards girls’ schools. This research note provides a brief account of the initiation and operation of the Industrial Fund. Although the Industrial Fund did provide fewer resources for girls’ schools this outcome stemmed from using the same and not different criteria for boys’ and girls’ schools and reflected the state of schools at the outset of the Industrial Fund.     

Flourishing Ethics

This essay describes a new ethical theory that has begun to coalesce from the works of several scholars in the international computer ethics community. I call the new theory ‚Flourishing Ethics’ because of its Aristotelian roots, though it also includes ideas suggestive of Taoism and Buddhism. In spite of its roots in ancient ethical theories, Flourishing Ethics is informed and grounded by recent scientific insights into the nature of living things, human nature and the fundamental nature of the universe – ideas from today’s information theory, astrophysics and genetics. Flourishing Ethics can be divided conveniently into two parts. The first part, which I call ‚Human-Centered FE,’ is focused exclusively upon human beings – their actions, values and characters. The second part, which I call ‚General FE,’ applies to every physical entity in the universe, including humans. Rather than replacing traditional ‚great ethical theories,’ Flourishing Ethics is likely to deepen and broaden our understanding of them.
