This introductory article to the combined special issue of Journalism Studies and Journalism Practice provides an overview of some of the key contemporary approaches to studying journalism and social order. It argues the need to step beyond a functionalist framework when considering the news media’s central role in shaping social connections, community and cohesion. To advance our understandings of social order, our paper suggests a greater emphasis of the significance of journalism’s relationship to the wider social sphere along with three other key considerations, including (1) a critical focus on the relationship between media, politics and social order, especially in defining and/or negotiating “anti-social” practices and social disintegration; (2) a more refined focus on the “imagined” and geographic boundaries of news audiences in digital spaces; and (3) the changing relationship to norms and conventions of journalism practice from trust and legitimacy to the role of journalists as arbiters and connectors across social spaces.  相似文献

Tim Henman was inarguably the best English player, and the most popular and socially significant British player, since Fred Perry. Throughout his career, media constructions of him fluctuated from being heralded as a potential Wimbledon champion, to a weak, underachieving perennial loser. Throughout his career, and despite the constant transition of dominant narratives, Henman’s quintessential ‘Englishness’ remained a key component, expressed through his image, appearance, ostensible personality/character and playing style. His ‘Englishness’ was especially apparent against the backdrop of the Wimbledon Championships, which used Henman’s success in its marketing of ‘tennis in an English garden’. This paper assesses the shifting meanings behind, and values of, Henman’s sustained image, and examines how changes in the narratives of Henman as a player reflected broader shifts in English identity. It is argued that Henman played a significant role in how Englishness was constructed, both in Britain and abroad, during the 1990s and 2000s.  相似文献

This article deals with kinematic and kinetic conditions in volleyball attack and identifies loads in the shoulder joint. Joint angles and velocities of individual segments of upper limb were measured with the use of the motion capture system XSENS. Muscle forces and loads in skeletal system were calculated by means of mathematical model elaborated in AnyBody system. Spikes performed by players in the best and worst way were compared with each other. The relationships were found between reactions in shoulder joint and flexion/extension, abduction/adduction and rotation angles in the same joint and flexion/extension in the elbow joint. Reactions in shoulder joint varied from 591 N to 2001 N (in relation to body weight [BW] 83–328%).

The analysis proved that hand velocity at the moment of the ball hit (which varied between 6.8 and 13.3 m s–1) influences on the value of reaction in joints, but positions of individual segments relative to each other are also crucial. It was also proved in objective way, that position of the upper limb during spike can be more or less harmful assuming that bigger reaction increases possibility of injury, what can be an indication for trainers and physiotherapists how to improve injury prevention.  相似文献
