Intrusive versus deliberate rumination in posttraumatic growth across US and Japanese samples.

Abstract: To examine the role of rumination in the aftermath of traumatic/stressful events, posttraumatic growth (PTG) and the four types of rumination (i.e., intrusive rumination soon after the event, intrusive rumination recently, deliberate rumination soon after the event, and deliberate rumination recently) were assessed retrospectively for participants from the USA (N=224) and Japan (N=431). The results from a hierarchical regression analysis revealed that the hypothesized relationships among the four types of rumination and PTG were largely supported. Intrusive rumination soon after the event was positively related to PTG but recent deliberate rumination most strongly predicted the current levels of PTG for both samples. Some evidence for cultural differences in the role of rumination in PTG was also observed. In the US sample, deliberate rumination recently was more important than the deliberate rumination in the immediate aftermath of the traumatic/stressful event, whereas in the Japanese sample, d...

Visualization Criticism - The Missing Link Between Information Visualization and Art

Abstract: Classifications of visualization are often based on technical criteria, and leave out artistic ways of visualizing information. Understanding the differences between information visualization and other forms of visual communication provides important insights into the way the field works, though, and also shows the path to new approaches. We propose a classification of several types of information visualization based on aesthetic criteria. The notions of artistic and pragmatic visualization are introduced, and their properties discussed. Finally, the idea of visualization criticism is proposed, and its rules are laid out. Visualization criticism bridges the gap between design, art, and technical/pragmatic information visualization. It guides the view away from implementation details and single mouse clicks to the meaning of a visualization.

A National Perspective on the Effects of High-Stakes Testing and Standardization on Elementary Social Studies Marginalization

Abstract: The purpose of this study was to explore the nationwide historic trend of elementary social studies marginalization compared to math, science, and language arts. Incorporating 17 years of data from the National Center for Educational Statistics (NCES) Schools and Staffing Survey, the authors conducted comparative analyses to investigate differences in instructional time between elementary social studies and other core subject areas. In addition, variance of social studies instructional time was examined across grade levels and survey years. The results indicate that social studies instruction has remained a subsidiary part of K-5 curriculum over the last two decades. Moreover, between grade-level analyses shows a trend toward greater attention to social studies in intermediate grades (3–5) compared to primary grades (K-2). A significant decline in social studies instruction coincided with educational policy that places greater importance on mathematics and language arts. The authors conclude that while No...

Posttraumatic Growth and Depreciation as Independent Experiences and Predictors of Well-Being

Abstract: Positive changes (posttraumatic growth [PTG]) and negative changes (posttraumatic depreciation [PTD]) were assessed using the PTGI-42 with persons reporting changes from a stressful event. PTG and PTD were uncorrelated, and PTG was much greater than PTD. PTG was positively related to disruption of core beliefs and recent deliberate rumination and negatively related to recent intrusive rumination. PTD was positively related to intrusive rumination. Quality of life and meaning in one's life were positively related to PTG, negatively related to PTD, and an interaction indicated that PTG moderated the impact of PTD on both, indicating that PTG and PTD may separately contribute to current well-being.

Directional asymmetry and the measurement of developmental instability

Abstract: Three widely used methods of estimating fluctuating asymmetry may yield serious overestimates if directional asymmetry is present. When two sides of a bilateral trait grow at different rates, then the asymmetry variance (Var[ l−r ]) increases with size, even when developmental noise is nil. But the residual variance around a population's mean developmental trajectory is invariant with respect to size. Thus, it can be used as a measure of developmental instability. We introduce a measure of developmental instability, the residual variance ( s 2 δ ), obtainable from either a major axis regression, which is equivalent to a principal component analysis on l and r , or a general structural model. This residual variance can be estimated from directionally asymmetric or even antisymmetric traits. We present examples of developmental instability estimated from directionally asymmetric mandibles (house mouse) and leaves (soybean), and antisymmetric claws (fiddler crab).
