This case examines dilemmas evolving in China’s premier soccer league, the Chinese Super League. A plan is suggested for confronting the league’s challenges, with recommendations that focus on creating a harmonious and competitive league. Challenges arise from the political and economic transformation currently taking place in China, affecting league operations. While the league stands at a precipice of change on the eve of the Beijing Olympic Games, its viability as a going concern is uncertain. Part of the uncertainty derives from an unregulated system of league policies that have been poorly communicated and unenforced, resulting in discord. Development of league regulations and communication protocols remains largely government driven and would be best if consistent with the local culture, but commercial issues of league operations are also important. Enhancing the effectiveness and consistency of culture-sensitive communication protocols—especially between the government, media, and league officials—will increase participation from league stakeholders.

Price dispersion reflects ignorance in the marketplace in which different prices exist from the same or different sellers for a similar good. One of the sources of price dispersion is uncertain demand for a business’s good or service. Ticket markets are good opportunities to examine a firm’s pricing strategy under demand uncertainty, because professional sports teams have to price their tickets well in advance of the actual event and before actual demand is known. The purpose of the present research is to examine the relationship between price dispersion and regular season average attendance in Major League Baseball. Using a two-step generalized method of moments (GMM) model, the present research finds that an increase in price dispersion leads to a decrease in average attendance.

The purpose was to conduct a qualitative cross-cultural comparison of the concerns of physical educators in two countries about integration of children with and without disabilities. In-depth interviews were held with 30 regular elementary physical education teachers in Berlin (7 males, 9 females) and in the Dallas-Ft. Worth (DFW) area (2 males, 12 females), and observations were made of school settings. The Concerns-Based Adoption Model (CBAM) of Hall, Wallace, and Dossett (1973) guided the study. Data were analyzed by grounded theory procedures. Many concerns about integration were generalizable across cultures. In both countries, teachers reported concerns at only four of the seven stages of CBAM: personal, management, consequence, and collaboration. Most concerns focused on management. The major cultural difference was that DFW teachers reported more personal concerns (uncertainty about everyday demands and competence to meet these demands) than Berlin teachers. A dynamic systems model was proposed to guide future research.

Research describing load-monitoring techniques for team sport is plentiful. Much of this research is conducted retrospectively and typically involves recreational or semielite teams. Load-monitoring research conducted on professional team sports is largely observational. Challenges exist for the practitioner in implementing peer-reviewed research into the applied setting. These challenges include match scheduling, player adherence, manager/coach buy-in, sport traditions, and staff availability. External-load monitoring often attracts questions surrounding technology reliability and validity, while internal-load monitoring makes some assumptions about player adherence, as well as having some uncertainty around the impact these measures have on player performance This commentary outlines examples of load-monitoring research, discusses the issues associated with the application of this research in an elite team-sport setting, and suggests practical adjustments to the existing research where necessary.
This article reports on time management in an elite sports context. It aims at characterizing how coaches experience dealing with athletes’ time management in a sport and academic institute and their constraints. Ten male coaches participated in this study. Each coach was asked to describe his time management activity during the season. Inductive and deductive analysis revealed two main results. The first showed the coaches dealt with a stringent set of constraints concerned with: (a) season organization, (b) training period and task sequencing, (c) the institute’s set times, and (d) the uncertainty linked to the evolution of training. The second emphasized that the coaches used three complex operating modes: (a) the use of organizational routines based on reference to past experience, (b) season shared time management, and (c) time management based on flexible plans. The results are discussed in relation to research that has considered planning and time management.

This article introduces a novel, ecological, obstructed walking paradigm. Gait adaptations to circumvent obstacles undergoing uncertain displacements, and the effect of revealing the obstacle’s action beforehand, were investigated in young adults. The personal space (PS) maintained during walking was quantified for the first time under different environmental factors including auditory distractions. Obstacle movement and its uncertainty resulted in gait adjustments aimed at gaining time to assess the situation. Early gait adaptations and constant clearances around the obstacle suggest that anticipation and preplanning are involved in such navigational tasks. Participants systematically maintained an elliptical PS during circumvention, but they adjusted its size according to different environmental factors. There was a relationship between the size of PS and level of attention, which suggests that the regulation of PS is used to control locomotion. This novel paradigm has important implications for the assessment and training of locomotor ability within real world environments.
This article uses economic theory to examine the variables that affect the competitive balance in a professional sports league and the impact of revenue sharing. The generally accepted proposition that revenue sharing does not affect the competitive balance in a profi t-maximizing league has been challenged by many. It is shown that the competitive balance and the impact of revenue sharing not only depend on the relative size of the market of the clubs, but that they are also affected by the objectives of the club owners and the importance to spectators of absolute team quality and uncertainty of outcome. Furthermore, the clubs’ hiring strategies, including the talent supply conditions, turn out to be important elements affecting competitive balance and the impact of revenue sharing.
What do disability labels give us and what do they steal from us? How possible is it to live our lives without categories when life is necessarily categorical? In this brief provocation, I want to explore the disability labels through recourse to three perspectives that have much to say about categorization, disability, and the human condition: the biopsychological, the biopolitical, and, what I term, an in-between-all politics. It is my view that disability categories intervene in the world in some complex and often contradictory ways. One way of living with contradictions is to work across disciplinary boundaries, thus situating ourselves across divides and embracing uncertainty and contradiction to enhance all our lives. I will conclude with some interdisciplinary thoughts for the field of adapted physical activity.

Objective methods can improve accuracy of physical activity measurement in field studies but uncertainties remain about their use.
Children age 11 years from the Avon Longitudinal Study of Parents and Children (ALSPAC), were asked to wear a uni-axial accelerometer (MTI Actigraph) for 7 days.
Of 7159 children who attended for assessment, 5595 (78%) provided valid measures. The reliability coefficient for 3 days of recording was .7 and the power to detect a difference of 0.07 SDs (P ≤ .05) was > 90%. Measures tended to be higher on the first day of recording (17 counts/min; 95% CI, 10–24) and if children wore the monitor for fewer days, but these differences were small. The children who provided valid measures of activity were different from those who did not, but the differences were modest.
Objective measures of physical activity can be incorporated into large longitudinal studies of children.

The Journal of Physical Activity and Health seems likely to develop as a vehicle for practical, evidence-based answers to problems concerning physical activity and health, issues that have important implications for public health policy. There is strong epidemiological evidence for an association between the regular practice of physical activity and preventive or therapeutic benefit in a wide range of chronic health conditions,1-4 and already many professional groups have been eager to pre¬pare position statements, indicating their assessments of an appropriate minimum weekly dose of physical activity to maintain health.5 Unfortunately, there have been substantial discrepancies between successive recommendations, and uncertainties in the message are one probable factor, limiting its acceptance by both the general public and immediate health-care providers.6,7 The purpose of this brief commentary is to suggest some areas of investigation that would help in formulating a clear and consistent message. Topics discussed include the desired health outcome, the shape of the dose–response relationship, the impact of confounding variables, the quality of the evidence accepted, the basis for shaping the message, and the need for multiple messages.
