Normative Bridges and Barriers in the Framing of Emerging Sports Movements

Abstract

Why have some small, emerging sports communities grown faster than others? To begin answering this question, the analysis presented here considers the case of disc golf, a flying disc sport that has grown rapidly since the early twenty-first century. This research conceptualizes the disc golf community as a new social movement and examines how the news media has influenced its development. Drawing on a large, diverse sample of local and national news materials, this study finds that the volume of disc golf news coverage is correlated with reliable measures of the sport’s growth. In addition, a content analysis of 2920 newspaper articles is used to identify the news frames that may promote, or attenuate disc golf’s “grow the sport movement.” The theoretical and methodological contributions of this study shed further light on the complex relationship between the news media and the evolution of small, non-normative sports movements.     

Relationships between period and cohort life expectancy: Gaps and lags

This paper offers an empirical and analytic foundation for regarding period life expectancy as a lagged indicator of the experience of real cohorts in populations experiencing steady improvement in mortality. We find that current period life expectancy in the industrialized world applies to cohorts born some 40–50 years ago. Lags track an average age at which future years of life are being gained, in a sense that we make precise. Our findings augment Ryder's classic results on period–cohort translation.

A meso measure? Examination of the levels of analysis of the Multifactor Leadership Questionnaire (MLQ)

Critical review of the Multifactor Leadership Questionnaire, Form 5X (MLQ5X), reveals serious problems related to specification of the theoretical level of analysis at which it measures its underlying constructs. Data from two separate samples indicate that items of the commonly used MLQ5X are ambiguous with respect to level of analysis. It appears unclear in many instances whether the items reflect individual, group, or organizational referents. Based upon our analyses and the literature, we present specific propositions concerning the level(s) at which each MLQ5X dimension appears most appropriately conceptualized and measured, along with suggestions for future research and revision of the MLQ5X.     

A Note on the Estimate of Treatment Effect from a Cox Regression Model When the Proportionality Assumption Is Violated

ABSTRACT

Cox proportional hazards regression model has been widely used to estimate the effect of a prognostic factor on a time-to-event outcome. In a survey of survival analyses in cancer journals, it was found that only 5% of studies using Cox proportional hazards model attempted to verify the underlying assumption. Usually an estimate of the treatment effect from fitting a Cox model was reported without validation of the proportionality assumption. It is not clear how such an estimate should be interpreted if the proportionality assumption is violated. In this article, we show that the estimate of treatment effect from a Cox regression model can be interpreted as a weighted average of the log-scaled hazard ratio over the duration of study. A hypothetic example is used to explain the weights.     

Analytic computation of nonparametric Marsan–Lengliné estimates for Hawkes point processes

In 2008, Marsan and Lengliné presented a nonparametric way to estimate the triggering function of a Hawkes process. Their method requires an iterative and computationally intensive procedure which ultimately produces only approximate maximum likelihood estimates (MLEs) whose asymptotic properties are poorly understood. Here, we note a mathematical curiosity that allows one to compute, directly and extremely rapidly, exact MLEs of the nonparametric triggering function. The method here requires that the number q of intervals on which the nonparametric estimate is sought equals the number n of observed points. The resulting estimates have very high variance but may be smoothed to form more stable estimates. The performance and computational efficiency of the proposed method is verified in two disparate, highly challenging simulation scenarios: first to estimate the triggering functions, with simulation-based 95% confidence bands, for earthquakes and their aftershocks in Loma Prieta, California, and second, to characterise triggering in confirmed cases of plague in the United States over the last century. In both cases, the proposed estimator can be used to describe the rate of contagion of the processes in detail, and the computational efficiency of the estimator facilitates the construction of simulation-based confidence intervals.     

Social psychology and neoliberalism: A critical commentary on McDonald,Gough, Wearing,and Deville (2017)

McDonald, Gough, Wearing, and Deville (2017) call for the discipline of social psychology to investigate issues of neoliberalism, consumption and self‐identity more seriously. We make two contributions in relation to their analysis. First, we highlight some current issues associated with neoliberalism as a concept that leave us in doubt regarding the analytical usefulness of the term. Due to its imprecision and over‐extension, predominant association with the left who use it pejoratively, and altered economic circumstances, we are increasingly skeptical of neoliberalism's analytical validity to social psychology. Second, we also stress the importance of interdisciplinarity, but suggest that empirical insights from mainstream social psychology have much to offer social scientists concerned with how current economic developments impact upon self‐identity and social behaviour. We conclude by pointing out that a greater openness to heterodoxy within and between critical and mainstream strands and the wider social sciences are required if social psychologists are going to make more persuasive impacts to the study and resistance of market logic.     

Instrumental Variables Estimates of the Effect of Subsidized Training on the Quantiles of Trainee Earnings

This paper reports estimates of the effects of JTPA training programs on the distribution of earnings. The estimation uses a new instrumental variable (IV) method that measures program impacts on quantiles. The quantile treatment effects (QTE) estimator reduces to quantile regression when selection for treatment is exogenously determined. QTE can be computed as the solution to a convex linear programming problem, although this requires first‐step estimation of a nuisance function. We develop distribution theory for the case where the first step is estimated nonparametrically. For women, the empirical results show that the JTPA program had the largest proportional impact at low quantiles. Perhaps surprisingly, however, JTPA training raised the quantiles of earnings for men only in the upper half of the trainee earnings distribution.
