“冰球”在哪里:高级体育媒体学术的十大主题

从消费、碎片化、变迁三个关键词入手,提出了未来美国体育与传播研究的十个主题,即消费分层背景下的体育与体育节目、体育赛事之外的主要消费、多视角的体育事件中的身份研究、关注传播效果研究、对媒介"妖魔化"的再思考、保持体育媒介研究身份前提下的多学科研究、学术研究成果的传播、决定什么是新方向、时间对消费行为的影响和关注被忽视的领域。报告认为从不同社会阶层的角度分析体育节目的观看行为、体育消费行为和媒介体育的传播效果是最重要的研究领域,体育事件中的性别身份研究、球迷身份研究、种族、民族和国家主义等多学科的交叉研究以及新技术、新媒介出现对体育新闻与传播的影响也将继续是美国体育新闻与传播研究的方向。     

A pillar of the Youngstown community: The Public Library of Youngstown and Mahoning County engages in the Harwood practice

ABSTRACT

The Harwood Institute arrived in Youngstown, Ohio, in 1999; and today, over 18 years later, its teachings have made a profound effect upon the city. The Youngstown Public Library, through the leadership of Carlton Sears and Heidi Daniel, has wholeheartedly embraced the methods and ideology of the Harwood Institute, helping to reinvigorate and power a city working its way back to prosperity.     

The effect of acceleration signal processing for head impact numeric simulations

Brain injury research in sport employs a variety of physical models equipped with accelerometers. These acceleration signals are commonly processed using filters. The purpose of this research was to determine the effect of applying filters with different cutoff frequencies to the acceleration signals used as input for finite element modeling of the brain. Signals were generated from reconstructions of concussion events from American football and ice hockey in the laboratory using a Hybrid III headform. The resulting acceleration signals were used as input for the University College Dublin Brain Trauma Model after being processed with filters. The results indicated that using a filter with a cutoff of 300 Hz or higher had little effect on the resulting strain measures. In some cases there was some effect of the filters on the peak linear (8–30g) and rotational measures (1000–4000 rad/s²), but little effect on the finite element strain result (approximately 2–6 %). The short duration and high magnitude accelerations, such as the puck impact, were most affected by the cutoff frequency of different filters.     

Assessment using the P scales: best fit – fit for the purpose?

In this article, Andrew Martin, deputy headteacher at Greenside School in Stevenage, provides an outline of the development of the P scales as an assessment tool for pupils working below Level 1 of the National Curriculum. He recounts the difficulties his school found in using P scales to track pupil progress from year to year and describes and evaluates a computer package which he devised in order to fulfil this function. He goes on to discuss current issues in the use of P scales, many of which were highlighted through use of the computer package. These issues include inconsistency in the use of the P scales; variations in pupil profiles; difficulties over making 'best fit' judgements; the need for moderation; and relationships with other curriculum and assessment systems in the school years and in the Foundation Stage. Andrew Martin closes his article with a call for consistency in approaches to assessment, particularly in view of the fact that P scale assessments are to be collected as part of statutory end of key stage data collection arrangements in future.
