Internal and External Validity of Sluggish Cognitive Tempo in Young Adolescents with ADHD

Adolescents with Sluggish Cognitive Tempo (SCT) show symptoms of slowness, mental confusion, excessive daydreaming, low motivation, and drowsiness/sleepiness. Although many symptoms of SCT reflect internalizing states, no study has evaluated the utility of self-report of SCT in an ADHD sample. Further, it remains unclear whether SCT is best conceptualized as a unidimensional or multidimensional construct. In a sample of 262 adolescents comprehensively diagnosed with ADHD, the present study evaluated the dimensionality of a SCT scale and compared CFA and bifactor model fits for parent- and self-report versions. Analyses revealed the three-factor bifactor model to be the best fitting model. In addition, SCT factors predicted social and academic impairment and internalizing symptoms. Therefore, SCT as a multidimensional construct appears to have clinical utility in predicting impairment. Also, multiple reporters should be used, as they predicted different areas of functioning and were not invariant, suggesting that each rater adds unique information

Transforming the Japanese comic tradition

Awkward gestures

A consideration of how irreverent approaches to fashion illustration can open a space for more critical approaches to the form - challenging idealised representations of the body, bringing a sense of 'humanness' to fashion or by reflecting on what our preoccupation with fashion says about human nature in the 21st Century. The article focussed on the work of Helen Bullock, Florence Shaw and Damien Florebert Cuypers and included interviews with all three in reference to the article topic. This article was commissioned by Varoom! for their politics themed issue

Using Operations Data for Planning the the Delaware Valley: First Steps

Real-time traffic operations data has been gathered for several years on an increasing number of roads throughout the Delaware Valley. The archives of this data are a tremendous potential resource for transportation planning. Use of the data, however, has posed significant technical challenges. This report summarizes how the data can be used, the state of operations data for planning in the Delaware Valley, and the results of two case studies. The first case study used data from the Pennsylvania Department of Transportation's Dynac system about speed and travel time on a section of I-76. The second case study used data provided by the I-95 Corridor Coalition Vehicle Probe Project (VPP) from INRIX, a private-sector traffic data company. The second case study analyzed duration of congestion on weekdays in 2009 for freeways in the Delaware Valley. This analysis was used in the region's 2011 Congestion Management Process

Extended minds and prime mental conditions: probing the parallels

Two very different forms of externalism about mental states appear prima facie unrelated: Williamson’s (1995, 2000) claim that knowledge is a mental state, and Clark & Chalmers’ (1998) extended mind hypothesis. I demonstrate, however, that the two approaches justify their radically externalist by appealing to the same argument from explanatory generality. I argue that if one accepts either Williamson’s claims or Clark & Chalmers’ claims on considerations of explanatory generality then, ceteris paribus, one should accept the other. This conclusion has implications for philosophy of mind, epistemology, and cognitive science
