The Role of Political Identity and Media Selection on Perceptions of Hostile Media Bias During the 2012 Presidential Campaign     

Mei-Chen Lin  Paul M. Haridakis  Gary Hanson 《广播与电子媒介杂志》2016,60(3):425-447

Viewing a hostile media bias against one’s group (e.g., political party) is a perceptual effect of media use. When it comes to the portrayal of political parties in the United States, prior research suggests that both Democrats and Republicans see mainstream media coverage as favoring the other side, regardless of the orientation of the political news coverage. Although prior research has not identified all factors that make this perceptual bias more likely, or at explaining how or why this perceptual effect occurs, we do know that it is related to one’s group identity. In this study, we examined salient predictors of hostile media bias during the 2012 presidential campaign. Individual (i.e., political cynicism) and group identity related (i.e., group status, intergroup bias, political ideology) differences of media users predicted such perceptions. But, the medium selected for political information about the campaign also mattered. The use of two media in particular—TV and social networking sites—appear to have blunted hostile media bias perceptions, whereas the use of two other media—radio and video sharing sites—appear to have accentuated perceptions that the media were biased against one’s party  相似文献   

‘Social Skills’: Following a Travelling Concept from American Academic Discourse to Contemporary Danish Welfare Institutions     

Annick Prieur  Sune Qvotrup Jensen  Julie Laursen  Oline Pedersen 《Minerva》2016,54(4):423-443

The article traces the origin and development of the concept of social skills in first and foremost American academic discourse. As soon as the concept of social skills was coined, the concern for people lacking such skills started and has been on the increase ever since (now sharing public attention with related concepts such as self-control, emotional intelligence and empathy). After the analysis of the academic history of the concept follows an examination of the implementation of a range of assessment instruments and training programmes related to social skills (and lack hereof) in contemporary Danish welfare institutions (more specifically, day nurseries and schools, employment and penal services). The analysis forwarded in the article thus demonstrates how an intellectual idea may develop and travel - and on its journey connect to pre-existing cultural logics and societal concerns. The idea of social skills has through its development been made uncontroversial – everybody wants to be skilful. The concept does, however, convey an individualistic view on social life and imposes a reflexivity over own performance on the participants. Further, its normative character contributes to a problematization of those who are perceived to lack these skills.  相似文献   

Self-reported symptoms and risk factors for digital ischaemia among international world-class beach volleyball players

The prevalence of ischaemia-related symptoms is remarkably high among elite indoor volleyball players. Since the exposure to sport-specific demands may be higher in beach volleyball compared to indoor volleyball, the aim of this study was to assess the prevalence of ischaemia-related symptoms and associated risk factors among world-class beach volleyball players. Therefore, a questionnaire survey was performed among beach volleyball players active during the 2013 Grand Slam Beach Volleyball in the Netherlands. In total, 60 of the 128 beach volleyball players (47%) participated: 26 males and 34 females from 17 countries. The self-reported prevalence of cold or blue or pale digits in the dominant hand during or immediately after practice or competition was 38% (n = 23). Two risk factors were independently associated with symptoms of blue or pale digits: more than 14 years playing volleyball (odds ratio (OR) 4.42, 90% confidence interval (90% CI) 1.30–15.07) and sex (female) (OR 4.62, 90% CI 1.15–18.57). In conclusion, the prevalence of symptoms associated with digital ischaemia is high among international world-class beach volleyball players. Female sex and the length of the volleyball career were independently associated with an increased risk of ischaemia-related symptoms. The high prevalence of these seemingly innocuous symptoms and possible associated risk factors warrant regular monitoring since early detection can potentially prevent thromboembolic complications and irreversible tissue damage.  相似文献   

Tier-specific evolution of match performance characteristics in the English Premier League: it’s getting tougher at the top     

Paul S. Bradley  David T. Archer  Bob Hogg  Gabor Schuth  Michael Bush  Chris Carling 《Journal of sports sciences》2016,34(10):980-987

This study investigated the evolution of physical and technical performances in the English Premier League (EPL), with special reference to league ranking. Match performance observations (n = 14,700) were collected using a multiple-camera computerised tracking system across seven consecutive EPL seasons (2006–07 to 2012–13). Final league rankings were classified into Tiers: (A) 1st–4th ranking (n = 2519), (B) 5th–8th ranking (n = 2965), (C) 9th–14th ranking (n = 4448) and (D) 15th–20th ranking (n = 4768). Teams in Tier B demonstrated moderate increases in high-intensity running distance while in ball possession from the 2006–07 to 2012–13 season (P < 0.001; effect size [ES]: 0.68), with Tiers A, C and D producing less pronounced increases across the same period (P < 0.005; ES: 0.26, 0.41 and 0.33, respectively). Large increases in sprint distance were observed from the 2006–07 to 2012–13 season for Tier B (P < 0.001; ES: 1.21), while only moderate increases were evident for Tiers A, C and D (P < 0.001; ES: 0.75, 0.97 and 0.84, respectively). Tier B demonstrated large increases in the number of passes performed and received in 2012–13 compared to 2006–07 (P < 0.001; ES: 1.32–1.53) with small-to-moderate increases in Tier A (P < 0.001; ES: 0.30–0.38), Tier C (P < 0.001; ES: 0.46–0.54) and Tier D (P < 0.001; ES: 0.69–0.87). The demarcation line between 4th (bottom of Tier A) and 5th ranking (top of Tier B) in the 2006–07 season was 8 points, but this decreased to just a single point in the 2012–13 season. The data demonstrate that physical and technical performances have evolved more in Tier B than any other Tier in the EPL and could indicate a narrowing of the performance gap between the top two Tiers.  相似文献   

A coach’s political use of video-based feedback: a case study in elite-level academy soccer     

Michael Booroff  Lee Nelson  Paul Potrac 《Journal of sports sciences》2016,34(2):116-124

This paper examines the video-based pedagogical practices of Terry (pseudonym), a head coach of a professional junior academy squad. Data were collected through 6 in-depth, semi-structured interviews and 10 field observations of Terry’s video-based coaching in situ. Three embracing categories were generated from the data. These demonstrated that Terry’s video-based coaching was far from apolitical. Rather, Terry strategically used performance analysis technologies to help fulfil various objectives and outcomes that he understood to be expected of him within the club environment. Kelchtermans’ micropolitical perspective, Callero’s work addressing role and Groom et al.’s grounded theory were primarily utilised to make sense of Terry’s perceptions and actions. The findings point to the value of developing contextually grounded understandings of coaches’ uses of video-based performance analysis technology. Doing so could better prepare coaches for this aspect of their coaching practice.  相似文献   

Quantifying the offensive sequences that result in goals in elite futsal matches     

Hugo Sarmento  Paul Bradley  M. Teresa Anguera  Tiago Polido  Rui Resende  Jorge Campaniço 《Journal of sports sciences》2016,34(7):621-629

The aim of this study was to quantify the type of offensive sequences that result in goals in elite futsal. Thirty competitive games in the Spanish Primera Division de Sala were analysed using computerised notation analysis for patterns of play that resulted in goals. More goals were scored in positional attack (42%) and from set pieces (27%) compared to other activities. The number of defence to offense “transitions” (n = 45) and the start of offensive plays due to the rules of the game (n = 45) were the most common type of sequences that resulted in goals compared to other patterns of play. The central offensive zonal areas were the most common for shots on goal, with 73% of all goals scored from these areas of the pitch compared to defensive and wide zones. The foot was the main part of the body involved in scoring (n = 114). T-pattern analysis of offensive sequences revealed regular patterns of play, which are common in goal scoring opportunities in futsal and are typical movement patterns in this sport. The data demonstrate common offensive sequences and movement patterns related to goals in elite futsal and this could provide important information for the development of physical and technical training drills that replicate important game situations.  相似文献   

Elite wheelchair rugby: a quantitative analysis of chair configuration in Australia     

David S. Haydon  Ross A. Pinder  Paul N. Grimshaw  William S. P. Robertson 《Sports Engineering》2016,19(3):177-184

Limited recommendations of wheelchair configurations for court sports have been identified in the published literature. To accommodate the wide range of impairments in wheelchair rugby, players are given a point score that reflects their impairment. Players have regularly been grouped as high-, mid-, or low-point players in research, with high-point players having greater levels of muscle function compared with other classifications. This research documented the wheelchair configurations of elite Australian wheelchair rugby players across classification groups. Significant differences (p < 0.05) were found for increased seat height and decreased seat depth for high-point players compared with low- and mid-point groups, respectively. Low-point players displayed reduced wheelchair mass compared with high- and mid-point players, as well as increased frame length. Camber angles showed no significant differences across the classification groups. The incorporation of anthropometric measures, such as the elbow angle at the top dead center, was also investigated. While elbow angle showed no significant differences, seat height-to-total arm length ratio was higher for high-point players. Participants also completed surveys detailing their perception of the effect of altering wheelchair configurations. It is suggested that wheelchair configurations should consider an individual’s anthropometrics, impairment, training history, and court role to promote optimal performance, with predictive modeling having the potential to reduce the associated time and cost.  相似文献   

Exploring the everyday realities of grass-roots football coaching: towards a relational perspective     

Paul Potrac  Lee Nelson  Jimmy O’Gorman 《Soccer & Society》2016,17(6):910-925

While scholars have increasingly engaged with the (micro)political and emotional experiences of coaches in professional and semi-professional football, little attention has been given to grass-roots coaches’ understandings of these issues. The aim of this paper is to outline one possible research agenda that could contribute to the development of a rich and increasingly nuanced understanding of the everyday realities of being a grass-roots football coach. In particular, we consider (volunteer) coaches’ participation in grass-roots football to be an inherently relational endeavour. Following the presentation of a creative fiction that is based upon our shared experiences of being grass-roots football coaches, we then illustrate how relational thinking might be productively applied to exploring the social, (micro)political and emotional features of grass-roots football coaching.  相似文献   

Effect of repeat-sprint training in hypoxia on post-exercise interleukin-6 and F2-isoprostanes     

Paul S. R. Goods  Brian Dawson  Grant J. Landers  Christopher J. Gore  Kevin Croft  Peter Peeling 《European Journal of Sport Science》2016,16(8):1047-1054

This investigation examined the oxidative stress (F₂-Isoprostane; F₂-IsoP) and inflammatory (interleukin-6; IL-6) responses to repeat-sprint training in hypoxia (RSH). Ten trained male team sport athletes performed 3(sets)*9(repetitions)*5?s cycling sprints in simulated altitude (3000?m) and sea-level conditions. Mean and peak sprint power output (MPO and PPO) were recorded, and blood samples were collected pre-exercise, and again at 8 and 60?min post-exercise. Both MPO and PPO were significantly reduced in hypoxia (compared to sea-level) in the second (MPO: 855?±?89 vs. 739?±?95?W, p?=?.006; PPO: 1024?±?114 vs. 895?±?112?W, p?=?.010) and third (MPO: 819?±?105 vs. 686?±?83?W, p?=?.008; PPO: 985?±?125 vs. 834?±?99?W, p?=?.008) sets, respectively. IL-6 was significantly increased from pre- to 1?h post-exercise in both hypoxia (0.7?±?0.2 vs. 2.4?±?1.4?pg/mL, p?=?.004) and sea-level conditions (0.7?±?0.2 vs. 1.6?±?0.3?pg/mL, p?d?=?0.80) suggesting higher IL-6 levels of post-hypoxia. F₂-IsoP was significantly lower 1?h post-exercise in both the hypoxic (p?=?.005) and sea-level (p?=?.002) conditions, with no differences between trials. While hypoxia can impact on exercise intensity and may result in greater post-exercise inflammation, it appears to have little effect on oxidative stress. These results indicate that team sport organisations with ready access to hypoxic training facilities could confidently administer RSH without significantly increasing the post-exercise inflammatory or oxidative stress response.  相似文献
