Young children's beliefs about the stability of traits: protective optimism?

Prior research has demonstrated individual differences in children's beliefs about the stability of traits, but this focus on individuals may have masked important developmental differences. In a series of four studies, younger children (5-6 years old, Ns = 53, 32, 16, and 16, respectively) were more optimistic in their beliefs about traits than were older children (7-10 years old, Ns = 60, 32, 16, and 16, respectively) and adults (Ns = 130, 100, 48, and 48, respectively). Younger children were more likely to believe that negative traits would change in an extreme positive direction over time (Study 1) and that they could control the expression of a trait (Study 3). This was true not only for psychological traits, but also for biological traits such as missing a finger and having poor eyesight. Young children also optimistically believed that extreme positive traits would be retained over development (Study 2). Study 4 extended these findings to groups, and showed that young children believed that a majority of people can have above average future outcomes. All age groups made clear distinctions between the malleability of biological and psychological traits, believing negative biological traits to be less malleable than negative psychological traits and less subject to a person's control. Hybrid traits (such as intelligence and body weight) fell midway between these two with respect to malleability. The sources of young children's optimism and implications of this optimism for age differences in the incidence of depression are discussed.     

Effect of Mouthguard Use on Metabolic and Cardiorespiratory Responses to Aerobic Exercise in Males

Purpose: This study investigated the physiological effects of wearing a mouthguard during submaximal treadmill exercise. Method: Twenty-four recreationally active males (M_age = 21.3 ± 2.4 years, M_height = 1.78 ± 0.06 m, M_weight = 81.9 ± 10.6 kg, M_{body mass index} = 25.8 ± 3.4 kg·m^?2) performed incremental, continuous exercise at 2, 4, 6, and 8 mph (3.2, 6.4, 9.7, 12.9 kph) for 5 min at each speed on a motor-driven treadmill on 2 separate occasions in a randomized, crossover, counterbalanced design while wearing or not wearing a self-adaptable “boil and bite” mouthguard. Respiratory rate (RR), tidal volume (V_T), ventilation (V_E), oxygen consumption (VO₂), respiratory exchange ratio (RER), and heart rate (HR) data were averaged during the last 60 s of each exercise stage; blood lactate (LA) was measured before exercise and 3 min and 10 min following exercise. Results: Repeated-measures analysis of variance revealed that mouthguard use failed to alter the response of RR, V_T, V_E, VO₂, RER, and HR to treadmill exercise (p > .05), although each variable did increase in magnitude as a result of increasing treadmill speed (p < .001). Although increasing to above resting values at both 3 min and 10 min (p < .001) after cessation of exercise, LA levels also displayed no differences with mouthguard use (p > .05). Conclusion: Despite predictable increases in respiratory, metabolic, and cardiovascular variables in response to incremental exercise, the presence of a mouthguard failed to affect the magnitude or nature of these physiological responses.     

Child pornography: perpetuating the sexual victimization of children

Children have been sexually exploited throughout recorded history. The invention of the camera and subsequent related technological advances (slides, movies, instant picture cameras and videotape) have provided new avenues for the exploitation of children by facilitating the distribution of pictorial representations of these children on a world-wide basis. A major use of commercial child pornography is to convince a potential child victim that the sexual acts desired by the adult offender are fun, exciting, can satisfy the child's curiosity and are a societally acceptable means of expressing affection. Commercial child pornography publications contain numerous pictures of children viewing child pornography, in some cases replicating the pose(s) depicted in the viewed material. Although many jurisdictions have now prohibited child pornography, the need for a world-wide ban continues, as the remaining producers distribute their material throughout the world.     

Do High-Quality Kindergarten and First-Grade Classrooms Mitigate Preschool Fadeout?

Prior research shows that short-term effects from preschool may disappear, but little research has considered which environmental conditions might sustain academic advantages from preschool into elementary school. Using secondary data from two preschool experiments, we investigate whether features of elementary schools, particularly advanced content and high-quality instruction in kindergarten and first grade, as well as professional supports to coordinate curricular instruction, reduce fadeout. Across both studies, our measures of instruction did not moderate fadeout. However, results indicated that targeted teacher professional supports substantially mitigated fadeout between kindergarten and first grade but that this was not mediated through classroom quality. Future research should investigate the specific mechanisms through which aligned preschool-elementary school curricular approaches can sustain the benefits of preschool programs for low-income children.     

NAEB research seminar for educational television and radio

To review the status of research in educational broadcasting, assess its adequacy in the light of contemporary requirements and propose a program of urgently needed research, 23 research specialists from organizations and institutions engaged in educational broadcasting participated in a five-day Seminar on Research in Educational Broadcasting. The Seminar was sponsored by the National Association of Educational Broadcasters with funds provided by the W. K. Kellogg Foundation. Management responsibility was handled by The Ohio State University, which also generously contributed the services of many members of its staff. The Seminar was held December 9–13, 1957, on The Ohio State University campus in Columbus. For the past few years, Dr. Tyler has been director of the annual Institute for Education by Radio and Television.     

Making learning fun: Quest Atlantis, a game without guns

This article describes the Quest Atlantis (QA) project, a learning and teaching project that employs a multiuser, virtual environment to immerse children, ages 9–12, in educational tasks. QA combines strategies used in commercial gaming environments with lessons from educational research on learning and motivation. It allows users at participating elementary schools and after-school centers to travel through virtual spaces to perform educational activities, talk with other users and mentors, and build virtual personae. Our work has involved an agenda and process that may be called socially-responsive design, which involves building sociotechnical structures that engage with and potentially transform individuals and their contexts of participation. This work sits at the intersection of education, entertainment, and social commitment and suggests an expansive focus for instructional designers. The focus is on engaging classroom culture and relevant aspects of student life to inspire participation consistent with social commitments and educational goals interpreted locally. This research was supported in part by a CAREER Grant from the National Science Foundation, REC-9980081 and by the National Science Foundation Grant #0092831.     

“Really Just Lip Service”: Talking About Diversity in Suburban Schools

Suburban school districts are in the midst of rapid racial/ethnic and socioeconomic diversification, although the teaching force remains much more homogenous. This article examines how educators in increasingly more diverse suburban schools conceptualize diversity. Qualitative data comes from interviews of 40 teachers, 23 principals and assistant principals, and 16 other school staff in six suburban school districts across the country. Using critical discourse analysis (van Dijk, 1993), I identify three primary discourses: an aspirational commitment to preparing students for a diverse society; color-muteness and insistence on individuality; and a deficit perspective on students from diverse racial/ethnic, linguistic, and socioeconomic backgrounds. In particular, educators perceived cultural deficits in students’ families and communities (Valencia, 2010). Finally, a small number of participants recognized structural forces that impeded the achievement of students of color. The discussion analyzes how such discourses threaten to reproduce educational inequality as suburban districts continue to diversify and concludes with recommendations for districts and schools.     

A Kinesiology Conundrum: Physical Activity Requirements in Kinesiology Degree Programs

One of the most long-standing controversies in kinesiology has been that of physical activity requirements (PARs) in corresponding degree programs. Despite a recommendation from the American Kinesiology Association to include “the practice of physical activity” in undergraduate kinesiology degree programs, some programs have PARs, while others do not. The question still remains: should physical activity be required for all kinesiology students? In this article, we build a case for PARs in kinesiology degree programs. First, we highlight the most common theoretical and practical objections to such requirements. The theoretical objections are namely dualism, materialism, and utilitarian pragmatism; the practical objections are cost, the credit crunch, and public perception. Second, and most importantly, we describe why these theoretical and practical objections fail. As unapologetic partisans on this issue, our primary aim is to highlight why PARs belong in every kinesiology degree program, regardless of concentration or area of emphasis.     

Part-time work and advancement: a study of female professional staff in Australian universities

One focus of gender equity policies in universities has been the creation of ‘retention’ part-time work for professional staff, which allows employees to move between full-time and part-time hours at their request. This paper examines whether such ‘good’ part-time jobs can contribute to or at least not impede women’s career advancement. The paper examines the correlation between job classification and part-time work, and whether a period of part-time work acts as a significant ‘brake’ on a woman’s career trajectory. This study uses data from the 2011 Work and Careers in Australian Universities survey. Part-time work is used extensively by lower-classified women, but rarely by those in higher classifications. Part-time work stalls career advancement compared to working full-time, but this brake is reduced if a woman transitions back to full-time work.     

Turn On,Tune In,Drop Out: Radio Listening,Ownership Policy,and Technology

Radio listening in the United States fell by more than 10% between 1998 and 2003. During this time, broadcast radio faced new competition from satellite radio and the Internet while the industry was also undergoing significant changes due to increased radio ownership caps. This article quantifies the effects of these factors on audience sizes and explores the implications for audience composition and programming content. The results show that industry consolidation played a larger role in decreasing overall listening than new technology. New technology did have a role in altering the distribution of listeners among programming formats.
