Changing the environment to promote health-enhancing physical activity

Supportive environments have been used to change and influence health behaviours like smoking. While psychological and ecological theories and models demonstrate the possible influences of the environment on health-enhancing physical activity (HEPA), little is known about the effectiveness of the environmental interventions. This paper presents the results of a systematic review of studies that used environmental interventions to increase health-enhancing physical activity. Two groups of studies were found, studies that changed the physical environment by creating new HEPA facilities, policies and supporting mechanisms, and studies that used the elements of the environment as an active or sedentary ‘point of choice’, via educational materials to promote stair use. Environmental change studies showed a small increase on HEPA behaviour, but the relative impact of environment changes was not evaluated. A number of before and after studies have observed a weak effect of a simple environmental change to stimulate stair climbing while travelling or shopping. Current national policy has embraced the environment as an option for promoting health-enhancing physical activity, especially active travel, in spite of the lack of effectiveness data. It is recommended that existing or planned public health environment and HEPA initiatives should use appropriate evaluation methods to assess their efficacy and effectiveness. Further developmental research into the nature of the relationship of the environment to particular HEPA behaviours is strongly recommended before developing new environmental interventions.     

Do pediatric chief residents recognize details of prepubertal female genital anatomy: a national survey

OBJECTIVE: To evaluate how well a group of recently trained pediatric chief residents could label anatomic structures on two different photographs of female prepubertal genitalia. Additionally, the study sought to explore aspects of pediatric training in sexual abuse and clinical practice issues surrounding the routine genital examination. METHOD: A 38-item questionnaire was mailed to pediatric chief residents at all of the officially listed pediatric residency-training programs in the continental US. Comparisons were made between this study and the responses to two previous surveys, which asked a more heterogeneous group of physicians to label one of the photographs used in the study. The second photograph was added because of its improved clarity of each anatomic structure when compared to the first photograph used in the previous studies. The study also asked about clinical practice issues surrounding the prepubertal genital examination. RESULTS: An overall response rate of 73% was achieved and analysis was done on 139 respondents. One-half of chief residents thought that their training during residency on sexual abuse was inadequate for practice. Sixty-four percent of chief residents correctly labeled the hymen on the photograph used in the previous studies, which was not significantly different from the 62% and 59% of physicians who correctly labeled the hymen in the previous surveys. In the second photograph, which more clearly displayed the various anatomic structures, 71% correctly labeled the hymen. CONCLUSION: Pediatric chief residents reported variable amounts of training on issues pertaining to child sexual abuse during residency, think that this time was inadequate, and, while doing slightly better than a more diverse group of previously studied physicians, did not achieve 100% accuracy in identifying basic genital structures correctly on two different photographs.     

Child Development and Neuroscience

Although developmental psychology and developmental neuroscience share interests in common problems (e.g., the nature of thought, emotion, consciousness), there has been little cross-fertilization between these disciplines. To facilitate such communication, we discuss 2 major advances in the developmental brain sciences that have potentially profound implications for under standing behavioral development. The first concerns neuroimaging, and the second concerns the molecular and cellular events that give rise to the developing brain and the myriad ways in which the brain is modified by both positive and negative life experiences. Recurring themes are that (1) critical, new knowledge of behavioral development can be achieved by considering the neurobiological mechanisms that guide and influence child development, and (2) these neurobiological mechanisms are in turn influenced by behavior.     

A Multidimensional Hierarchical Model of Physical Fitness: A Basis for Integration and Collaboration

For operational purposes, physical development is characterized using a multidimensional hierarchical model. Optimal physical development is described as a combination of good physical fitness and a high level of skill development. Physical fitness has multiple subdimensions of its own. Developing each subdimension requires regular physical activity, which is not likely to occur without the collaboration of many, including the individual, family, friends, schools, community, and private agencies.     

Debate in the house of commons

Richard M. Weaver, a “painful rememberer” of the past, calls rhetoric back to its traditional concern for eternal verities. Memory is the precondition of the historicity invoked, and is therefore prized in Weaver's writings.     

Changing Perspectives in the History of Education

Abstract

This articles identifies four issues whose resolution will shape the future of American elementary and secondary education. These are as follows. (1) Will the principle of decentralised control prevail over the seemingly inexorable tendency to consolidate power at the centre? (2) Will continuing emphasis on mass education obscure increasing demands to improve quality and raise achievement levels? (3) Will schools advance equality of educational opportunity, or reproduce inequalities inherent in the society? (4) Will schools integrate culturally heterogeneous populations at the expense of legitimate expressions of ethnic cultures? This article shows how these issues mirror ambiguities underlying American democratic principles, and offers some comparisons to conditions of education in Europe.     

A SHORT‐TERM FORECASTING PROCEDURE FOR INSTITUTION ENROLLMENTS

Institutions of higher education are finding that forecasting enrollments is of critical importance in the current environment of steady and declining student populations. Accurate short‐term enrollment forecasts provide valuable information to administrators for budgeting, planning, and (in the case of state supported institutions) negotiating with funding agencies. This research suggests that Box‐Jenkins (ARIMA) models may be used to produce accurate short‐range forecasts of seasonal enrollment data. One‐step ahead (one academic quarter ahead) forecast errors of Full Time Equivalent Students (FTES) for the Virginia Community College System are on the order of 3.6% with errors increasing in magnitue to 5.6% for forecasts one year into the future. The methodology employed in this paper to forecast VCCS enrollments can be adapted easily and inexpensively to forecasting enrollments at other institutions.
