Appropriate measurement of competitive balance is central to the economic analysis of professional sports leagues. We examine the distributional properties of the ratio of standard deviations (RSD) of points percentages, the most widely used measure of competitive balance in the sports economics literature, in comparison with other standard‐deviation‐based measures. Simulation methods are used to evaluate the effects of changes in season length on the distributions of competitive balance measures for different distributions of the strengths of teams in a league. The popular RSD measure performs as expected only in cases of perfect balance; if there is imbalance in team strengths, its distribution is sensitive to changes in season length. It is therefore not recommended for comparisons of competitive balance for different sports leagues with different numbers of teams and/or games played. (JEL L83, D63, C63) 相似文献

Alliances have long been an important strategy for health promotion and community development. They are now becoming an important approach to generating research that is thought to have real-world relevance and easy applicability because of the involvement of community members. A comprehensive, dynamic model of community impacts of research partnerships in social or health services is presented. This process-oriented, systems model outlines three major domains of mid-term impact (Enhanced Knowledge, Enhanced Research Skills, and Use of Information) that correspond to the core functions of collaborative research partnerships discussed in the literature (i.e. knowledge generation, research education and training, and knowledge sharing). The model will assist research partners, intended recipients, and funders to understand and evaluate the real-world impacts of community–university research partnerships. The model provides research partnerships with a tool to demonstrate their accountability and to improve their operations and impacts, and evaluators with a tool to guide planning and evaluation efforts. 相似文献

This paper uses research from two projects, conducted for Sport England and for the Central Council of Physical Recreation (CCPR), to analyze pressures on volunteers in sport in the United Kingdom (UK). Both research projects were contract research, conducted to inform policy and therefore were not designed to build on theoretical insights. However, from the results the research developed an understanding of the interrelated pressures on the voluntary sector in sport, which was informed by theory. This paper describes the pressures and relates them to previous research into volunteers. Contextualizing the issues faced by volunteers in sports organizations suggests several questions for further academic work, not only focussed on sports volunteers, but the voluntary sector in general. In particular, are the pressures experienced by the voluntary sector in UK sport common to sports volunteers in other countries, and to what extent are they also a reflection of general pressures on the voluntary sector? 相似文献

The literature of long-range planning is replete with justifications of the need for strategic planning and admonitions concerning its critical importance. However, both the literature of planning and its practice, as manifested in a variety of organizations as diverse as industrial firms, educational systems and law enforcement agencies, are deficient in specifying proven techniques and methodologies for marshalling organizational resources to effectively implement strategic planning.Over a period of years, the authors have consulted with a variety of business organizations and public agencies in the development and implementation of long-range planning processes. From this work has come an empirically-tested conclusion that the success of long-range planning in an organization is less sensitive to the parameters of the planning techniques that it is to the overall culture within which the planning is accomplished. Since most of the non-pontifical literature of planning focuses on planning techniques and specifications for planning processes, these conclusions suggest a critical void in planning methodology. 相似文献

Toddler toy play evolves in a predictable manner and provides a valid, nonverbal measure of cognitive function unbiased by social behaviors. Research on prenatal maternal stress (PNMS) indicates that exposure to stress in utero results in developmental deficits. We hypothesized that children exposed to high objective PNMS from a natural disaster early in pregnancy would exhibit higher rates of stereotypical play and lower rates of mature functional play than their low‐stress counterparts would. We examined the functional play abilities of 52 2‐year‐olds exposed to low or high objective PNMS from a natural disaster within a nonstructured play session. Toddlers exposed to high objective PNMS, subjective PNMS, or both exhibited less functional and more stereotypical toy play, with less diversity, compared to toddlers exposed to low PNMS. PNMS appears to affect functional play development in toddlers negatively. These results replicate delays in language and intellectual functioning observed in these toddlers using the Bayley Scales. 相似文献

Organizations often respond to allegations of wrongdoing made by whistle-blowers. Response mechanisms may take several forms, from simply denying the wrongdoing, to offering an apology. This study sought to examine the various response strategies an organization employed after a whistle-blowing incident. Using the whistle-blowing case of Brown and Williamson Tobacco Company, this study sought to examine the different image restoration strategies the organization (Brown and Williamson) used in responding to the allegations of wrongdoing made by the whistle-blower, Dr. Jeffrey Wigand. 相似文献

In consulting, finance, and other service industries, customers represent a revenue stream, and must be acquired and retained over time. In this paper, we study the resource allocation problem of a profit maximizing service firm that dynamically allocates its resources toward acquiring new clients and retaining unsatisfied existing ones. The interaction between acquisition and retention in our model is reflected in the cash constraint on total expected spending on acquisition and retention in each period. We formulate this problem as a dynamic program in which the firm makes decisions in both acquisition and retention after observing the current size of its customer base and receiving information about customers in danger of attrition, and we characterize the structure of the optimal acquisition and retention strategy. We show that when the firm's customer base size is relatively low, the firm should spend heavily on acquisition and try to retain every unhappy customer. However, as its customer base grows, the firm should gradually shift its emphasis from acquisition to retention, and it should also aim to strike a balance between acquisition and retention while spending its available resources. Finally, when the customer base is large enough, it may be optimal for the firm to begin spending less in both acquisition and retention. We also extend our analysis to situations where acquisition or retention success rate, as a function of resources allocation, is uncertain and show that the optimal acquisition and retention policy can be surprisingly complex. However, we develop an effective heuristic for that case. This paper aims to provide service managers some analytical principles and effective guidelines on resource allocation between these two significant activities based on their firm's customer base size. 相似文献
