In this paper, we propose an objective principal components weighting scheme for all-time Winter Olympic gold, silver and bronze medals based solely on the number of medals won. Our results suggest that the approximately equal weights be assigned (or the total medal counts be used regardless of color) if all of the three medal types are retained for ranking purposes. When the proposed methodology is tested against five alternative weighting schemes that have been suggested in the literature using the results for the 2010 Vancouver Winter Olympics, we find a significant agreement in the country rankings. Furthermore, our implementation of principal components variable reduction strategy results in the identification of silver as the best representative medal count for parsimonious Winter Olympics rankings.KEYWORDS: Olympic rankings, principal components analysis, variable reduction strategy, medal counts, objective weighting schemeJEL Classifications: C18, C38, C43 相似文献

Based on likely future changes in faculty evaluation practices, this paper examines how institutions of higher education might operationalize performance evaluation as related to research, teaching, and service. A model is developed that allows coupling performance evaluation and relevant market considerations with merit pay, tenure, and promotion decisions. The approach is specifically applicable to tenure-track faculty members in colleges and universities. 相似文献

In this work we suggest the use of the Gini index on control charts. The asymptotic properties of Gini index are presented and the control charts based on appropriate confidence intervals are constructed. The suitability of the proposed charts are investigated by means of extensive simulations. 相似文献

By examining the experiences of the children of Palestinian collaborators whose families have relocated to Israel, this study explores how youth negotiate self within the context of marginalisation and cultural dislocation. Due to the actions of their parents, the research participants have become outsiders and outcasts in their Palestinian communities of origin, outsiders in Israel, and outsiders among Israeli-Arabs. Based on qualitative, in-depth interviews with 11 Palestinian male youths, we describe and analyse the experience of identity negotiation in the context of fear and their families’ past deceit. Our findings highlight that the youths’ identities are negotiated by engaging in a dialogue of self on belonging and not belonging that is based on visions of their past, present and future selves. This is accompanied by a forced dialogue with others, explaining who they are in order to fit in with the ‘audience’, a presentation that is then acted out. 相似文献

ABSTRACTThere are substantial gaps in research on Health Related Quality of Life (HRQoL) in students aged 18 and above in West Virginia. The purpose of this study is to explore the associations between mindful self-care, perceived stress, and the HRQoL in this population. We conducted a cross-sectional study between March and April 2017. We included participants who were students, aged 18 years and above, living in West Virginia and were able to answer online questions in English. Data was obtained from an online survey using a structured questionnaire, including the SF12v2®, mindful self-care scale- SHORT, and Perceived Stress Scale (PSS)-10. We applied linear regressions to determine the predictors of HRQoL (physical health and mental health) using SF12v2®. 194 participants met the inclusion criteria of the study. Mindful self-care was negatively associated with perceived stress. Better mindful self-care mediated the relationship between perceived stress and psychological well-being, controlling for gender, age, race, marital status, education level, annual household income, and chronic disease status. Perceived stress and mindful self-care were not related to the physical well-being. Better mindful self-care may safeguard against perceived stress among students aged 18 years and above. Our findings in this study recommend more mindfulness-based interventions targeted to this subpopulation to improve psychological well-being. 相似文献

This paper discusses the advantages and challenges of using qualitative methods to elicit poor children’s perspectives about
threats and positive influences on their wellbeing. It draws on research carried out by the author on the subjective experiences
of poor children in Addis Ababa, the capital of Ethiopia in terms of their understandings of wellbeing, threats to their wellbeing,
coping strategies, and positive or resilient outcomes. After a brief introduction reviewing previous approaches to child poverty
in general and research on Ethiopian children in particular, the second section describes the research setting and the ethical
approach to the study, which influenced how consent was obtained and the data analysed. The paper then describes the use of
qualitative methods such as semi-structured interviews, draw-and-tell, and diaries, the kinds of data they produced and the
methodological and ethical dilemmas and tensions encountered in using them. It concludes that despite the challenges qualitative
methods are invaluable in order to understand what poor children see as threats and positive influences on their wellbeing.

An analytical survey of man-machine interactive procedures is presented. A decision maker's capabilities to carry out some information processing operations are discussed. A list of a decision maker's elementary operations used in different interactive procedures is given and their estimations from a psychological point of view are suggested. Three main criteria for estimation of man-machine procedures are proposed: reliability of information elicitation from decision maker, insignificant sensitivity to random decision maker's errors, and good speed of convergence to solution. Some procedures are evaluated in terms of these criteria. 相似文献

The global factory literature suggests that MNCs can take advantage of global operations by extensively offshoring and outsourcing activities. However, the added difficulty for the lead firm to coordinate the resulting complex structure is often underestimated. Evidence could be found in Boeing's 787 Dreamliner project, in which the external complexity disrupted MNC performance. Motivated by the gap between theory and practice, this study focuses on systems of MNCs connected with each other with supplier-client relationships and/or outsourcing. In particular it investigates the interplay of the internal and external complexity in such systems and how their balance affects the system performance. The study models the internal and external complexity by using the NKC-simulation methodology and adjusting it to the specific MNC context. The NKC methodology is widely used in organization theory to study complex systems. Simulations comparing the performance of MNCs that use outsourcing to different degrees indicate that a balanced level of internal and external complexity is beneficial in the context of global factory. 相似文献

Increasing family diversity during the past half century has focused national attention on how children are faring in nontraditional family structures. Much of the limited evidence on children in same‐sex couple families suffers from several shortcomings, including a lack of representative data. We use the National Health Interview Survey (2004–2012) and the National Survey of Children's Health (2011–2012) to identify children in different‐sex married and cohabiting families, never and previously married single‐parent families, and same‐sex couple families. Considering important characteristics such as the child's race or ethnicity and adoption status, household socioeconomic standing, family stability, and parent health, we examine the relationship between family type and parent‐rated overall child health. The results suggest that poorer health among children in same‐sex couple as well as different‐sex cohabiting couple and single‐parent families appears to be largely the product of demographic and socioeconomic differences rather than exposure to nontraditional family forms. 相似文献
