Support for EE From the National Science Education Standards and the Internet

Abstract

Two recent developments are likely to have a significant impact on the future of EE: (1) education reform initiatives based on the National Science Education Standards and (2) the development of promising Internet resources for teaching environmental sciences. This article urges the EE community to recognize that the time is ripe for environmental educators to embrace these developments. We examine several Internet-based resources that are used as tools for implementing standards-based reforms and promotion of EE's goals in K-12 classrooms.     

Developmental Personality Types From Childhood to Adolescence: Associations With Parenting and Adjustment

This study examined whether changes in children's self‐reported Big Five dimensions are represented by (developmental) personality types, using a cohort‐sequential design with three measurement occasions across 5 years (four cohorts, 9–12 years at T1; N = 523). Correlates of, and gender differences in, type membership were examined. Latent class growth modeling yielded three personality types: Resilients (highest initial levels on all Big Five), Overcontrollers (lowest Extraversion, Emotional Stability, Imagination), and Undercontrollers (lowest Benevolence, Conscientiousness). Gender differences in type membership were small. Warm parenting, but not overreactive discipline, in childhood was associated with type membership. The types differed in adjustment problems by the end of middle adolescence. Personality change more likely occurs at the level of dimensions within types than in type membership.     

Heat transfer variations of bicycle helmets

Abstract

Bicycle helmets exhibit complex structures so as to combine impact protection with ventilation. A quantitative experimental measure of the state of the art and variations therein is a first step towards establishing principles of bicycle helmet ventilation. A thermal headform mounted in a climate-regulated wind tunnel was used to study the ventilation efficiency of 24 bicycle helmets at two wind speeds. Flow visualization in a water tunnel with a second headform demonstrated the flow patterns involved. The influence of design details such as channel length and vent placement was studied, as well as the impact of hair. Differences in heat transfer among the helmets of up to 30% (scalp) and 10% (face) were observed, with the nude headform showing the highest values. On occasion, a negative role of some vents for forced convection was demonstrated. A weak correlation was found between the projected vent cross-section and heat transfer variations when changing the head tilt angle. A simple analytical model is introduced that facilitates the understanding of forced convection phenomena. A weak correlation between exposed scalp area and heat transfer was deduced. Adding a wig reduces the heat transfer by approximately a factor of 8 in the scalp region and up to one-third for the rest of the head for a selection of the best ventilated helmets. The results suggest that there is significant optimization potential within the basic helmet structure represented in modern bicycle helmets.     

Risks and Risk-Based Regulation in Higher Education Institutions

Complementary and alternative medicine as represented in the HIV/AIDS body of knowledge: a bibliometric analysis

Although the HIV/AIDS epidemic began more than twenty years ago, there still is no cure for the disease and no vaccine to prevent infection. As with the general population, individuals with HIV/AIDS have sought care using a variety of traditional and nontraditional approaches. The popularity of complementary and alternative interventions among the HIV/AIDS community continues. To understand better the distribution of the HIV/AIDS body of knowledge concerning complementary and alternative medicine (CAM), this study sought to (1) examine the literature specific to the use of complementary and alternative medicine where HIV/AIDS is concerned to determine publication patterns; (2) determine the degree of overlap among bibliographic citation databases that index the literature concerning the use of CAM practices in treating HIV/AIDS; and (3) facilitate access to this body of literature.
