Towards evidence-based classification in wheelchair sports: impact of seating position on wheelchair acceleration

In most Paralympic wheelchair sports, active trunk range of movement is assessed by observing shoulder girdle excursion during active trunk movements and is a key determinant of an athlete's class. However, to date research evaluating the impact of reduced trunk range of movement on wheelchair sports performance has not been conducted. In the present study, 15 non-disabled male participants performed two 20-s sprints on a wheelchair ergometer in each of three seating positions. Positions were typical of those used to enhance sitting stability in wheelchair sport and each impacted available trunk range of movement differently: condition-90 (seated with thighs horizontal; unrestricted range of movement) condition-45 (seated with thighs in 45°), and condition-0 (seated with hips maximally flexed; minimum range of movement). In condition-90, the trunk only actively contributed to the first push; for the remainder of the sprint, the trunk was held almost isometrically at 48.2° to the horizontal (range 42.1-56.4°). Similar patterns were observed for both condition-45 and condition-0. Compared with condition-90, participants in condition-0 had reduced capacity to accelerate of statistical (P < 0.05) and practical significance. These findings are an important initial step towards evidence-based decision making in classification. Future research should evaluate the individual and collective impact of other factors that affect the trunk's contribution to wheelchair sports performance, including strapping, seating position, and impairments of trunk muscle power and coordination.     

A computer simulation model of tennis racket/ball impacts

A forward dynamics computer simulation for replicating tennis racket/ball impacts is described consisting of two rigid segments coupled with two degrees of rotational freedom for the racket frame, nine equally spaced point masses connected by 24 visco-elastic springs for the string-bed and a point mass visco-elastic ball model. The first and second modal responses both in and perpendicular to the racket string-bed plane have been reproduced for two contrasting racket frames, each strung at a high and a low tension. Ball/string-bed normal impact simulations of real impacts at nine locations on each string-bed and six different initial ball velocities resulted in <3% RMS error in rebound velocity (over the 16–27 m/s range observed). The RMS difference between simulated and measured oblique impact rebound angles across nine impact locations was 1°. Thus, careful measurement of ball and racket characteristics to configure the model parameters enables researchers to accurately introduce ball impact at different locations and subsequent modal response of the tennis racket to rigid body simulations of tennis strokes without punitive computational cost.     

Empowering teachers to implement innovative content in physical education through continuous professional development

The purpose of this study was to examine teacher perceptions regarding their experiences in a research-informed continuous professional development (CPD) initiative and its influence on their professional readiness to implement innovative content in physical education (PE). Participants included four PE teachers who engaged in a series of hands-on workshops and collaborative activities related to the design and implementation of a mountain biking unit in two middle schools. Qualitative data were collected through post-workshop surveys, semi-structured interviews, and a focus group. Data were analyzed using inductive content analysis, and results revealed four themes: (a) igniting change, (b) transferring to the classroom, (c) student response, and (d) sustaining beyond a single unit. Findings from this study reinforce the need for research-informed CPD efforts in PE and highlight its role in generating a sense of teacher empowerment and promoting systemic change within school-based PE.     

The violence of peace and the role of education: insights from Sierra Leone

Research on peacebuilding has mushroomed over the last decade and there is a growing interest in the role of education in supporting peacebuilding processes. This paper engages with these debates, UN peacebuilding activities and the location of education initiatives therein, through a case study of Sierra Leone. In the first part, we explore the complex and multi-dimensional nature of violence in post-conflict Sierra Leone. In the second, we critically address the role of education in the conflict and post-conflict period, highlighting education’s centrality as a catalyst to conflict, and then reflect on the failure of the post-conflict reconstruction process to adequately transform the education system into one that could support a process of sustainable peacebuilding. Finally, we conclude by exploring the ways that greater investment and focus, both financial and human, in the education sector might, in the long term, better contribute to a sustainable and socially just peace.     

Teaching an Old Dog New Tricks: Past,Present, and Future Priorities For Higher Education Physical Activity Programs

Physical education programs in colleges/universities have been called on to provide students with opportunities to develop an appreciation for, and increase participation in, lifetime physical activity. Higher Education Physical Activity Programs (HEPAPs) have evolved over the past 100 years in response to changing societal and institutional expectations. The purpose of this article is to celebrate the long history of HEPAPs and recommend innovative strategies for program development that will maintain their position as a valued aspect of campus life. After tracing the historical roots and trends of HEPAPs, the authors suggest (a) adopting a public health perspective, (b) applying theoretical models as a framework for program development, (c) focusing on meaningful learner engagement, and (d) employing learner-centered instructional approaches. Within these overall themes, specific recommendations for program improvement are provided, including the use of alternative content areas, model-based instruction, universal design, instructional technology, and professional development for faculty/staff.     

If You Build It,They Will Come (or Not): Going the Distance in Teacher Candidate Recruitment

There are persistent concerns in the literature related to recruitment and retention of highly qualified teacher candidates who are capable of achieving contemporary goals and meeting the professional expectations associated with the delivery of quality physical education programs in schools. The purpose of this article is to provide physical education teacher education faculty with recommendations for best practice in the area of teacher candidate recruitment by reviewing literature in the following areas: (a) identification of the characteristics of successful teachers as a basis for recruitment efforts, (b) fundamental principles of effective marketing and recruitment, (c) generational characteristics of college-bound students and the practical implications, and (d) recruitment of underrepresented populations. The recruitment tactics identified include actionable recommendations for faculty, departments/programs, universities, and community partners in teacher education.     

Empathy and critical thinking: primary students solving local environmental problems through outdoor learning

The present study explores the outcomes of teaching empathy and critical thinking to solve environmental problems. This investigation was done throughout the duration of an environmental education course within a primary school located in central Chile. A community-based research methodology was used to understand the formation of empathy and critical thinking. The findings reveal a significant benefit in using empathy strategies to engage students regarding the thinking processes involved with solving environmental problems. Using these elements as teaching techniques for environmental education courses can be very helpful in reaching the aims of creating a sustainable citizenry.     

Humor in High-Stress Relationships: Understanding Communication in Police Officers' Romantic Relationships

A career in law enforcement is highly stressful given the nontraditional shiftwork, uncertain interactions, and risk of harm. These combined stressors likely spillover into one's romantic relationship and, thus, the study reported here explored one potential communicative coping mechanism—humor. Research exploring humor suggests that humorous communicators are better able to respond to stress, and this study explored if humor appears to benefit relational communication in police officer relationships. Findings begin to support this argument, revealing that romantic partners of police officers with a high humor orientation (HO) report using humor more to cope as well as experiencing less stress (both perceived and physical) and conflict (lower frequency of conflict and less intense/hostile conflict). Path analyses revealed that the use of humor to cope mediated the relationships between self-reported HO and stress, as well as conflict. Implications for humor and romantic relational communication are discussed.     

Testing Lesniaski's Revised Brief Test

In 2004, Lesniaski revised White's Brief Test methodology for smaller academic libraries that lack sufficient subject specialist librarians to perform the brief tests as originally proposed by White. As a part of regular collection development, Cowles Library implemented Lesniaski's Brief Tests on the print monograph collection. While primarily a review of Lesniaski's methodology, this article also discusses how the Brief Tests were used for improved collection evaluation and maintenance.
