Cardiovascular and ventilatory responses during formalized T'ai Chi Chuan exercise

T'ai Chi Chuan (TCC) is a widely practiced Chinese martial art said to physically develop balance and coordination as well as enhance emotional and mental health. TCC consists of a series of postures combined into a sequential movement providing a smooth, continuous, low-intensity activity. The purpose of this study was to examine the ventilatory and cardiovascular responses to the Long Form of Yang's style TCC. In addition, the subjects' TCC responses were compared to their ventilatory and cardiovascular responses during cycle ergometry at an oxygen consumption (VO2) equivalent to the mean TCC VO2. Six experienced (M = 8.3 yrs) male TCC practitioners served as subjects with data collected during the Cloud H and movement of the TCC exercise. Significantly (p less than .05) lower responses for ventilatory frequency (Vf) (11.3 and 15.7 breaths.min-1), ventilatory equivalent (VE/VO2) (23.47 and 27.41), and the ratio of dead space ventilation to tidal volume (VD/VT) (20 and 27%) were found in TCC in comparison to cycle ergometry. The percentage of minute ventilation used for alveolar ventilation was significantly higher during TCC (p less than .03) than cycle ergometry, with mean values of 81.1% and 73.1%, respectively. Cardiac output, stroke volume, and heart rate were not significantly different between TCC exercise and cycle ergometry at the same oxygen consumption. We concluded that, during TCC, expert practitioners show significantly different ventilatory responses leading to more efficient use of the ventilatory volume than would be expected from comparable levels of exertion on a cycle ergometer.     

Breaking the Cycle: Future Faculty Begin Teaching with Learner-Centered Strategies after Professional Development

The availability of reliable evidence for teaching practices after professional development is limited across science, technology, engineering, and mathematics disciplines, making the identification of professional development “best practices” and effective models for change difficult. We aimed to determine the extent to which postdoctoral fellows (i.e., future biology faculty) believed in and implemented evidence-based pedagogies after completion of a 2-yr professional development program, Faculty Institutes for Reforming Science Teaching (FIRST IV). Postdocs (PDs) attended a 2-yr training program during which they completed self-report assessments of their beliefs about teaching and gains in pedagogical knowledge and experience, and they provided copies of class assessments and video recordings of their teaching. The PDs reported greater use of learner-centered compared with teacher-centered strategies. These data were consistent with the results of expert reviews of teaching videos. The majority of PDs (86%) received video ratings that documented active engagement of students and implementation of learner-centered classrooms. Despite practice of higher-level cognition in class sessions, the items used by the PDs on their assessments of learning focused on lower-level cognitive skills. We attributed the high success of the FIRST IV program to our focus on inexperienced teachers, an iterative process of teaching practice and reflection, and development of and teaching a full course.     

Yer Doin’ it Wrong: How NOT to Interact with Vendors,Publishers, or Librarians

Three librarians who have extensive experience working in libraries or for publishers, vendors, or consortia presented an informal discussion on librarian–vendor relationships. The audience was encouraged to participate. Problems were articulated; speakers and audience members contributed suggestions for better approaches or behaviors when handling difficult situations.     

#MeToo,sexual harassment: an article,a forum,and a dream for the future

#MeToo has breathed new life into the women’s movement and especially into understanding and rectifying sexual harassment, abuse and assault. It has galvanized activists around the globe. And it has placed thousands of stories of the harassed in full view of the public. Sexual harassment, abuse and assault may occur within the organizational context or beyond; but sexual harassment, in particular has been legally labeled an organizational phenomenon. With this in mind, Robin Clair frames the early part of this article around the most recent organizational communication theories (see the appendix for an overview of these theories). Following the essay is a forum, in which invited scholars address questions related to the #MeToo movement.     

Building Inclusive Pedagogy: Recommendations From a National Study of Students of Color in Higher Education and Student Affairs Graduate Programs

In this study, we share the racialized experiences of 29 students of color in higher education and student affairs graduate programs, focusing specifically on their relationships with faculty, their experiences in classrooms, and the strategies they recommend for inclusion. Participants indicated that they are expected to serve as the racial expert in classrooms and that many faculty fail to effectively facilitate discussions related to race and racism and to intervene in instances of racial microaggressions. Participants convey effective strategies to build racially-inclusive classrooms which include authenticity, vulnerability, and validation.

From the cheap seats: one consideration of school-based PE's position in contemporary American schools

Background: As the USA enters the second decade of the twenty-first century, it does so in a polarized political, social, and educational climate heretofore unseen in its relatively short history. Such a climate has implications for what role schools play in American society and especially how school-based physical education (SBPE) may need to reinvent how and what it contributes to the schooling of American children and, ultimately, the common good. Currently, SBPE receives verbal endorsement from the public and politicians yet little in the way of policy and financial support from legislators at national, state, and local levels.

Aims: The purpose of this essay is to present a US-centered perspective on the current ‘position’ of SBPE and offer some modest (and hardly earth-shattering) suggestions for the immediate future from the perspective of a mid-career physical education teacher educator. Recommendations are made that may enable SBPE to make valuable contributions (perhaps even more that it currently does) and, hopefully, remove SBPE from the divided debate on what public schooling should include and how it should be provided.

Conclusions: SBPE is in a precarious position where it can be severely wounded or even wiped out by those issues plaguing it or it can emerge from this time as a subject matter of great import. More importantly, it can emerge as this important piece of education on its own terms.     

点燃思维之火：开放教育，长尾理论和学习2．0

高等教育需求和服务供给的矛盾为基于新技术的学习模式提供了空间.基于实践社区支持,强调参与、建构和兴趣驱动的社会化学习等非正式学习开始从边缘走向中心.本文讨论技术支持下的学习模式变革,强调整合社区支持和资源共享的重要性,从学习知识(Learn about)向学会生存(Learn to be)转变,并指出以资源共享为主的开放教育资源在社区支持方面的薄弱.开放教育资源的价值在学习的长尾中得到了揭示和体现,而建立社区与共享资源同样重要.通过建立参与性学习生态系统,推动从Web2.0发展到Learning2.0.
