Effects of stance width on performance and postural stability in national-standard pistol shooters

Abstract

The aim of the present study was to determine whether changing stance width would result in a corresponding change in postural and/or pistol stability. Twelve national-standard male air pistol shooters performed 10 shots each at five stance widths (30 cm, 45 cm, 60 cm, 75 cm, and 90 cm). Postural stability was determined by measuring centre-of-pressure changes with a dual force-platform system. Shooting mechanics measures were determined by a NOPTEL ST-2000 optoelectronic training system. Medial-lateral centre-of-pressure excursion (F _4,44 = 7.17, P < 0.001, effect size = 0.99) and speed (F _4,44 = 77.03, P < 0.001, effect size = 3.88) were reduced as stance width decreased. Centre of gravity fine (the percentage of time held within an area the size of the ten-ring) improved during narrower stance widths (F _4,32 = 12.49, P < 0.001, effect size = 0.71). Our findings suggest that stance width affects postural and pistol stability in national-standard air pistol athletes. Moreover, the current method of suggesting a wider stance to improve shooting performance should be reconsidered and perhaps air-pistol shooters should use a 30-cm stance width to improve postural stability and shooting performance.     

Crossing Borders, Breaking Boundaries: Collaboration Among Higher Education Institutions

Partnerships and collaboration have become popular in higher education; and partnerships with community agencies, K-12 schools, and businesses are common. However, formal and sustained partnerships among institutions of higher education are not nearly as widespread. This article presents a model for collaboration in higher education focused on a partnership among teacher preparation programs at three institutions. The article provides an overview of theoretical underpinnings for collaboration, the process and practices used, and lessons learned by Valley Partnership, as well as the stages of partnership development, the governance model, and key elements related to sustaining the partnership.     

Pedagogical Media Competencies of Preservice Teachers in Germany and the United States: A Comparative Analysis of Theory and Practice

Teachers need knowledge and skills to make effective use of the growing variety of media and technology texts and tools available for use in elementary and secondary education. For this reason, pedagogical media competencies are highly relevant for teachers’ professional development. The theory of media pedagogical competencies is first defined and then located in the context of the relevant scholarly literature from both Germany and the United States. We conducted a comparative analysis of German and U.S. pedagogical media competency models and report data on a survey of teacher education programs in Germany and the United States to identify the proportion of programs of study that include courses in media didactics, media and school reform, and media education. We consider the implications of the missing connections between the theoretical framework of pedagogical media competencies and the current practice of media pedagogical teacher training, revealing implications for further work needed to improve the integration of media in various school-related contexts.     

Developing Positive Attitudes Toward Interprofessional Collaboration Among Students in the Health Care Professions

This study examined whether attitudes toward interprofessional collaboration (Physician-Nurse, Physician-Social Worker, Nurse-Social Worker) held by medical, social work, and nursing students changed after completing an interprofessional curriculum consisting of (a) Interprofessional Education Development Session and (b) the Senior Aging and Geriatrics Educator mentoring program. The 15-item original and two modified versions of the Jefferson School of Attitudes Toward Physician-Nurse Collaboration (JSAPNC) were administered as pretest/posttest. Of the 186 participants who completed the pretest, 156 (84%) completed the posttest. Results showed that the medical students (n = 52) reported the most positive change in attitude toward all three pairs of interprofessional collaboration. Social work students (n = 55) reported the least positive attitudes toward Physician-Social Worker collaboration and nursing students (n = 49) reported the least positive attitudes toward Physician-Nurse collaboration. It is recommended to evaluate the interprofessional curriculum and other factors, such as the possible influence of the facilitator in group discussions, and that future studies include a rigorous design that monitors content of each educational session to ensure integrity across groups. Postgraduate follow-up measures could be used to enhance positive attitudes toward interprofessional collaboration.     

Aging in Suburbia: An Assessment of Senior Needs

To date, there have been no surveys focusing on older adults living in suburban communities. As the majority of American seniors reside in suburbia, it is important to understand factors that impede successful aging in these settings. This study surveyed 1,151 seniors to examine the needs of seniors living in a large suburban community across two counties in the northeastern United States. Specific areas of query included the following: transportation, health status, social support, self-sufficiency, and economic factors. Findings revealed that seniors over 85, minorities, those reporting poor health, and those who do not drive were at especially high risk of service access problems and social isolation.     

An exploration of school mobility: Risks and protective factors in late elementary

This study explored negative emotional, behavioral, and academic performance outcomes for highly mobile students and potential protective factors. Participants were fourth and fifth-grade students (N = 647, 51% male) from three schools with low socioeconomic status, highly mobile student populations within a large, suburban school district in the midwestern United States. Data were collected through student self-report surveys, teacher-report surveys, and school records. Multilevel moderation analysis tested whether school connectedness (SC) or social and emotional competence (SEC) acted as protective factors for highly mobile students, moderating the effect of school mobility on emotional problems and academic performance. Student mobility was associated with more emotional problems and lower academic performance. In contrast to past research, there was not an association between mobility and behavior problems. Although they did not act as protective factors, SC and SEC were independently associated with fewer emotional problems and stronger reading performance for all students, controlling for mobility. Results build on existing evidence that student mobility has negative effects on emotional and academic outcomes and lend support for interventions focused on enhancing SC and SEC of all students, including those at increased risk due to high mobility.     

Socioeconomic status,mental wellbeing and transition to secondary school: Analysis of the School Health Research Network/Health Behaviour in School-aged Children survey in Wales

Young people's wellbeing is often lowest where they assume a relatively low position within their school's socioeconomic hierarchy, for example, among poorer children attending more affluent schools. Transition to secondary school is a period during which young people typically enter an environment which is more socioeconomically diverse than their primary school. Young people joining a school with a higher socioeconomic status intake relative to their primary school may assume a relatively lowered position within their school’s socioeconomic hierarchy, experiencing a detriment to their wellbeing as a consequence. This article draws on data from 45,055 pupils in Years 7 and 8, from 193 secondary schools in Wales, who completed the 2017 Student Health Research Network (SHRN) Student Health and Wellbeing (SHW) survey. Pupils reported which primary school they previously attended, and survey data on wellbeing were linked to publicly available data on the free school meal entitlement of schools attended. In cross-classified linear mixed-effects models, with primary and secondary school as levels, mental wellbeing varied significantly according to both primary and secondary school attended. A higher school-level deprivation was associated with worse mental wellbeing in both cases. Mental wellbeing was significantly predicted by the relative affluence of a child's primary and secondary school, with movement to a secondary school of higher overall socioeconomic status associated with lowered wellbeing. These findings highlight transition to secondary school as a key point in which socioeconomic inequality in wellbeing may widen, and thus as an important focal point for intervention to reduce health inequalities.     

Shifting Perspectives on Comparative Research: A view from the USA

The evolution of scholarship in comparative education in the USA has reached a point where several observations are possible. While there is variation in methodology and theory, three principal perspectives tend to be represented in most contemporary articles published in the top journals in the field. These might be referred to as being area studies based, social science disciplinary based, or development/planning studies based. In this article we briefly trace the evolution of these perspectives, identify some stress points in the field, and look ahead to whether or not the field is facing competition among these perspectives or convergence. We suggest that the field of comparative education, not being bound by one or another of these perspectives, can play a significant role in the reconstruction of learning.     

Choices and Commitment: A Comparison of Teacher Candidates' Profiles and Perspectives in China and the United States

In this article, the researchers report findings from a recent national study of teacher education in China, in comparison to similar data from national and case studies in the United States. The study aims at understanding and comparing the profiles and entry perspectives of Chinese versus American teacher candidates. The researchers demonstrate that there are both similarities and differences in the demographic characteristics of the Chinese and American teacher candidates. The Chinese education students come from less privileged backgrounds in socioeconomic status and academic preparation. Although they share some of the noble ideas about becoming teachers, the overwhelming majority of the Chinese students do not intend to commit to teaching as a lifelong career. They cite the low status of the teaching profession and the poor benefits for teachers as primary reasons for leaving teaching. The researchers urge Chinese and American policy makers and teacher educators to revise their policies and practices in light of the study findings in order to recruit qualified young people into teacher education programs and more importantly to retain good teachers in the profession.
