Bidirectional relationships of physical activity and gross motor skills before and after summer break: Application of a cross-lagged panel model

Background:Gross motor skills are postulated to have a bidirectional relationship with physical activity(PA);however,no study has tested this relationship before and after a summer break.The purpose of this study was to examine the bidirectional relationships between school PA and gross motor skills in children before and after a summer break.Methods:Participants were a sample of 440 children recruited from 3 low-income schools(age=8.9±1.2 years,mean±SD).PA was assessed as average school-day step counts using Yamax DigiWalker pedometers(Yamasa Tokei Keiki,Tokyo,Japan)worn for 5 consecutive school days.Gross motor skills were assessed using the Test for Gross Motor Development,3 rd edition.Data were collected at 2 timepoints:at the end of spring semester(T1)and at the beginning of the subsequent fall semester(T2).An age-and body mass index-adjusted cross-lagged model was employed to relate T1 school step counts with T2 gross motor skills and T1 gross motor skills with T2 school step counts.Results:T1 gross motor skills significantly predicted T2 school step counts(β=0.24,95%confidence interval(95%CI):0.08-0.40,p=0.003);however,Tl school step counts did not predict T2 gross motor skills(β=0.04,95%CI:-0.06 to 0.14,p=0.445).The model explained 35.4%and 15.9%of the variances of T2 gross motor skills and T2 school step counts,respectively.Additional analyses indicated that these relationships were driven primarily by ball skills.Conclusion:The relationship between gross motor skills and school PA was not bidirectional;however,higher gross motor skills,specifically ball skills,predicted higher school PA after a 3-month summer break.     

Development and validation of the groupwork skills questionnaire (GSQ) for higher education

The aim of the present study was to develop and provide psychometric evidence in support of the groupwork skills questionnaire (GSQ) for measuring task and interpersonal groupwork skills. A 46-item version of the GSQ was initially completed by 672 university students. The number of items was reduced to 15 following exploratory factor analyses, and a two-factor model consisting of task and interpersonal groupwork skills was revealed. Confirmatory factor analyses with model re-specification on new data (n = 275 students) established that the best fitting model consisted of 10 items and the same two factors (task and interpersonal). Concurrent validity of the GSQ was then determined with 145 participants by demonstrating significant relationships (p < 0.05) with attitudes towards groupwork and groupwork self-efficacy. Test–retest reliability was examined over a one-week interval. Overall, the GSQ demonstrates good validity and reliability, and has potential for both research and pedagogical application.     

The cost of academic leadership: Department Chair Stress

Department chairs find themselves trapped between the stresses of performing not only as an administrator but faculty member as well. Over eight hundred chairs from 101 doctorate-granting and research universities were surveyed using the Department Chair Stress Index to assess (1) their most stressful situations, (2) emergent themes from these Stressors, and (3) the differences between chair and faculty Stressors. Chairs experienced most stress from their heavy workload and the general stresses of time pressures, confrontation with colleagues, organizational constraints and their faculty duties. Chairs were found to be in a paradoxical situation; feeling double pressure to be an effective leader and productive faculty member. Suggested actions for the institution and individual are provided.Walter H. Gmelch is professor and chair of the Educational Administration Department at Washington State University where he also serves as Director of the National Center for the Study of Department Chair. He earned his MBA from the University of California (Berkeley) and a Ph.D. in the Educational Executive program from the University of California (Santa Barbara). Dr. Gmelch conducts research on the topics of leadership, team development, conflict, stress and time management. His extensive writings include a co-authored book entitled,Strategic Leadership Skills for Department Chairs. John S. Burns is associate director of the Center for the Study of the Department Chair at Washington State University. He obtained a Master's in Counseling Psychology and a Ph.D. in Educational Administration from Washington State University. The Center's research agenda focuses on collecting data about the position of department chair with the goal of developing research-based recommendations for the restructuring of the administration of higher education.     

Who needs memory? the case for the Markovian organisation

This paper examines the contradiction of organisational memory: that an organisation requires a memory to operate effectively, but that that same memory inhibits and constrains its ability to operate effectively. We briefly review the field of organisational memory and note its close connection with organisational learning.We introduce a conceptual framework pioneered by Schultze and Stabell for examining contradictions in the area of knowledge management. We use this framework to distinguish between the conventional view of organisational memory, which implicitly or explicitly regards knowledge as a commodity, and a constructivist view, from which emerges a picture of the Markovian organisation: an organisation the future behaviour of which is determined not by memories of the past but by its current state, characterised by an organisational consciousness informed by the activities in which it is engaged. While the emphasis of this paper is theoretical, we suggest that adopting this Markovian view of the organisation might be particularly appropriate to practitioners in organisations that are immersed in turbulent environments.     

A look at the single parent family: Implications for the school psychologist

The purpose of this article is to: (a) review briefly the efects on parents and children of living in a single parent family, and (b) to suggest ways in which a school psychologist can aid schools and single parent families in dealing more effectively with this type of structure. School-based interventions for children and parents are presented. These include achievement and behavioral assessment, evaluation of a child's support systems, counseling groups, bibliotherapy, parent education classes, in-service training for teachers, and referrals to community agencies. Changes in administrative policies to meet the needs of single parent families are suggested.
