Ancient Greek ‘Amateurism’, the NCAA and the Courts

The National Collegiate Athletic Association (NCAA) has recently been the target of many lawsuits challenging its definition and regulation of amateurism, which it holds as providing unique moral and social benefits for both its scholar-athletes and society at large. This conception of amateurism is inherited from nineteenth-century models of ancient Greek athletics via figures such as John Mahaffy and E.N. Gardiner. This influence is evident in legal cases involving the NCAA or athletics in general, and hence amateurism is cited by judges and others as a long-standing Western cultural tradition which encourages moral and social development. This is problematic, however, as not only is it historically questionable, but also the citation of cultural heritage in legal dicta has seen legal criticism or reversal.     

Analysis of accelerometer-derived interpersonal spatial proximities: A calibration,simulation, and validation study

The purpose of this study was to estimate distances from accelerometer-derived Bluetooth signals as a measure of interpersonal spatial proximity. Accelerometer-derived proximity data were collected indoors and outdoors over a 10m range to calibrate simulation models. Proximity data were simulated over 20m (indoor) and 50m (outdoor) ranges. Competing statistical and machine learning models were used to predict simulated distances; the Root-Mean-Square-Error (RMSE) was calculated. Simulation estimates were validated under conditions wherein a single beacon-receiver (SBR) and multiple beacons-receivers (MBR) collected proximity data indoors and outdoors within a ≤10m range. Simulation data showed that a Random Forest (RF) model performed optimally. The validated RF RMSE was ≤2.7 for SBR, and ≥90% of predicted distances were accurately classified as ≤10m. For MBR, ≥67% of predicted distances were accurately classified as ≤10m. Simulation and validation data suggest that distances can be estimated from accelerometer-derived proximity data within a 20m range using a SBR.     

Adaptive Equilibrium Regulation: Modeling Individual Dynamics on Multiple Timescales

Damped Linear Oscillators estimated by 2nd-order Latent Differential Equation have assumed a constant equilibrium and one oscillatory component. Lower-frequency oscillations may come from seasonal background processes, which non-randomly contribute to deviation from equilibrium at each occasion and confound estimation of dynamics over shorter timescales. Boker (2015) proposed a model of individual change on multiple timescales, but implementation, simulation, and applications to data have not been demonstrated. This study implemented a generalization of the proposed model; examined robustness to varied timescale ratios, measurement error, and occasions-per-person in simulated data; and tested for dynamics at multiple timescales in experience sampling affect data. Results show small standard errors and low bias to dynamic estimates at timescale ratios greater than 3:1. Below 3:1, estimate error was sensitive to noise and total occasions; rates of non-convergence increased. For affect data, model comparisons showed statistically significant dynamics at both timescales for both participants.     

School violence,school differences and school discourses

This article highlights one strand of a study which investigated the concept of the violence‐resilient school. In six inner‐city secondary schools, data on violent incidents in school and violent crime in the neighbourhood were gathered, and compared with school practices to minimise violence, accessed through interviews. Some degree of association between the patterns of behaviour and school practices was found: schools with a wider range of well‐connected practices seemed to have less difficult behaviour. Interviews also showed that the different schools had different organisational discourses for construing school violence, its possible causes and the possible solutions. Differences in practices are best understood in connection with differences in these discourses. Some of the features of school discourses are outlined, including their range, their core metaphor and their silences. The authors suggest that organisational discourse is an important concept in explaining school effects and school differences, and that improvement attempts could have clearer regard to this concept.     

Multi-sited global ethnography and travel: gendered journeys in three registers

This paper joins a barely begun conversation about multi-sited and global ethnography in educational research; a conversation that is likely to intensify along with growing interest in the links between education, globalisation, internationalisation and transnationalism. Drawing on an ongoing multi-sited global ethnography of elite schools and globalisation, this paper explores the role of travel in multi-sited global ethnography and offers a feminist engagement with it. It considers the idea of fieldwork as a travel practice through three different travel registers; the traveller’s tale, critical travel studies and travel as exile. In so doing, it illustrates the reflexive affordances each register offers with regard to the directions of our feminist inquiries into elite schools and our feminist ethnographic practices.
