Tensions in Community Health Improvement Initiatives: Communication and Collaboration in a Managed Care Environment

Between the years 1993 and 2000, the W. K. Kellogg Foundation sponsored the Comprehensive Community Health Models (CCHMs) Initiative in three Michigan counties. CCHMs was comprised of three closely related community initiatives carried out in the midst of a failed national health care reform effort and the continued penetration of managed care arrangements into many health care systems. This experimental initiative set out to test the hypothesis that traditional healthcare system animosities and exclusionary practices could be overcome by stakeholder participation in an ongoing, structured, collaborative dialogue about improving access to health services. In the process of collecting data through surveys, interviews, content analysis, and observation, we were struck by the occurrence of several overarching tensions that we perceive to exist in our data. The present article elucidates five such tensions and suggests how third parties such as communication researchers, evaluators, and practitioners can facilitate community health improvement initiatives and better their own data interpretation by acknowledging and understanding these tensions.     

Relative age and maturation selection biases in academy football

ABSTRACT

This study examined the simultaneous effects of relative age and biological maturity status upon player selection in an English professional soccer academy. A total of 202 players from the U9 to U16 age groups, over an eight-year period (total of 566 observations), had their relative age (birth quarter) and biological maturity (categorised as late, on-time or early maturing based upon the Khamis-Roche method of percentage of predicted adult height at time of observation) recorded. Players born in the first birth quarter of the year (54.8%) were over-represented across all age groups. A selection bias towards players advanced in maturity status for chronological age emerged in U12 players and increased with age; 0% of players in the U15 and U16 age group were categorised as late maturing. A clear maturity selection bias for early maturing players was, however, only apparent when the least conservative criterion for estimating maturity status was applied (53.8% early and 1.9% late maturing in the U16 age group). Professional football academies need to recognise relative age and maturation as independent constructs that exist and operate independently. Thus, separate strategies should perhaps be designed to address the respective selection biases, to better identify, retain and develop players.     

The relationship between game-based performance indicators and developmental level in junior Australian football: Implications for coaching

Identifying performance differences between juniors at different stages of a talent pathway may assist with the development of prospective talent. This study investigated the relationship between game-based performance indicators and developmental level in junior Australian football (AF). Players were categorised into 2 groups according to developmental level; U16 and U18. Physical and technical skill performance indicators were collated for all U16 (n = 200) and U18 (n = 244) participants of their respective 2014 national championships. Data were acquired from all 28 games (12 U16, 16 U18); resulting in 1360 player observations (568 U16, 792 U18). Microtechnology and a commercial provider facilitated the quantification of 15 performance indicators. Generalised estimating equations (GEEs) modelled the extent to which these performance indicators were associated with developmental level. The GEE model revealed that “contested marks” and “contested possessions” had the strongest association with the U16 level, while “total marks” and “clearances” had the strongest association with the U18 level. The remaining performance indicators were not developmentally discriminant. These results indicate that there are distinctive features of gameplay more associated with the U16 and U18 levels in AF. Coaches may wish to consider these results when constructing training drills designed to minimise developmental gaps.     

Machine and deep learning for sport-specific movement recognition: a systematic review of model development and performance

Objective assessment of an athlete’s performance is of importance in elite sports to facilitate detailed analysis. The implementation of automated detection and recognition of sport-specific movements overcomes the limitations associated with manual performance analysis methods. The object of this study was to systematically review the literature on machine and deep learning for sport-specific movement recognition using inertial measurement unit (IMU) and, or computer vision data inputs. A search of multiple databases was undertaken. Included studies must have investigated a sport-specific movement and analysed via machine or deep learning methods for model development. A total of 52 studies met the inclusion and exclusion criteria. Data pre-processing, processing, model development and evaluation methods varied across the studies. Model development for movement recognition were predominantly undertaken using supervised classification approaches. A kernel form of the Support Vector Machine algorithm was used in 53% of IMU and 50% of vision-based studies. Twelve studies used a deep learning method as a form of Convolutional Neural Network algorithm and one study also adopted a Long Short Term Memory architecture in their model. The adaptation of experimental set-up, data pre-processing, and model development methods are best considered in relation to the characteristics of the targeted sports movement(s).     

Football friends: adolescent boys’ friendships inside an English professional football (soccer) academy

This qualitative research draws on data from semi-structured, in-depth interviews to examine the friendships of 12 adolescent (14- and 15-year-old) boys within a professional football club Academy: a setting marked by competition for places. Findings highlight how boys fail to develop ‘deep’ friendships with other boys inside the club; their peer-relationships, even when described as ‘friendships’, are devoid of trust and emotional intimacy. Instead, ‘being mates’ is experienced within parameters of instrumentalism and individualism leading to superficial and inauthentic friendships. There is some indication that boys developed closer friendships with boys outside of the Academy, suggesting that competition is implicated negatively in friendship-building and hinders the capabilities of these boys to develop close friendships with teammates. Concluding this paper, we acknowledge limitations of our data, discuss implications and challenges for football academies, and highlight directions for future research.     

Relationship between perceived acculturation expectations and Muslim minority youth's acculturation and adaptation

Acculturation strategies have frequently been used to describe how members of ethnic minorities reconcile their heritage culture with the culture of their society of residence. Recently, studies have started to pay increased attention to the fact that the choice of acculturation strategy does not take place in a social vacuum. In the present study, we test whether the perception of assimilation expectations held by the societal majority (PSAE) as well as separation expectations held by ethnic peers (PESE) may be related to individuals’ own acculturation strategy. Furthermore, we investigate whether these perceived expectations are directly related to stress and indirectly to adaptation, mediated by acculturation strategies. All relationships were investigated using multi-group structural equation modeling with members from three Muslim minority groups: 301 German-Turks, 302 French-Maghrebis and 262 British-Pakistanis. Across the samples, PSAE was associated with higher degrees of stress. PESE was negatively related to integration, while it was positively related to separation. In addition, PESE was indirectly and negatively related with self-esteem and/or socio-cultural adaptation in all samples. The impact of societal assimilation expectation appears to be limited in this regard. In all, the present study suggests that perceived acculturation expectations may influence ethnic minorities’ acculturation strategy. The results also suggest that perceived expectations that contrast with individuals’ personal acculturation preference could result in higher levels of stress and lower levels of psychological and socio-cultural adaptation, mediated by acculturation strategies.
