Embedded programming and real-time signal processing of swimming strokes

The research outlined in this paper was conducted to allow real-time processing, transmission and presentation of data to swimming coaches and subsequently their swimmers in a training environment, focused on providing information relevant to strokes in free swimming. This was achieved using a wearable wireless sensor and embedded programming techniques, using accelerations involved in the swimming stroke to provide relevant features for coaches. Current methods used do not offer real-time response to coaches, which results in the lack of real-time feedback and significantly increased post-session analysis time. Filtering and signal processing algorithms are described here, which allow real-time data analysis to be embedded within a wireless sensor node. The system significantly reduces the time for processing acquired data and has delivered a novel monitoring device suitable for operation within the harsh environment of the pool.

Temporal patterns of schedule-induced drinking and pawgrooming in rats exposed to periodic food

Five rats were exposed to fixed-time food schedules, ranging from 30 to 480 sec. Three rats displayed a postfood pattern of schedule-induced drinking, with short latencies from food delivery to drinking at all interfood interval durations. In contrast, drinking for the other 2 subjects tended to occur at lower overall levels, and drinking bouts frequently began in the middle of the interfood interval, such that the latency from food delivery to drinking increased dramatically as the interfood interval increased. Observation of these 2 subjects revealed that another form of licking-pawgrooming-occurred reliably after food delivery and before drinking bouts. A between subject comparison of the 3 postfood drinkers and the 2 pawgroomers revealed that, in addition to a common topography (repetitive licking), pawgrooming and drinking were similar with respect to their temporal locus, relation to the interfood interval, and extinction baseline levels. These similarities suggest that drinking and pawgrooming are induced by a common mechanism. Cohen, Looney, Campagnoni, and Lawler’s (1985) two-state model of reinforcer-induced motivation provides a useful framework for the interpretation of these results.     

Comparing motor development of deaf children of deaf parents and deaf children of hearing parents

Deaf children of Deaf parents perform better academically (Ritter-Brinton & Stewart, 1992), linguistically (Courtin, 2000; M. Harris, 2001; Vaccari & Marschark, 1997), and socially (Hadadian & Rose, 1991; M. Harris, 2001) than Deaf children of hearing parents. Twenty-nine Deaf children in residential schools were assessed to determine if a significant difference also exists in motor development between Deaf children with Deaf parents and Deaf children with hearing parents. In the locomotor area, 78.6% of Deaf children of Deaf parents and 73.3% of Deaf children of hearing parents reached or surpassed average performance levels. In regard to object control, 92.9% of Deaf children of Deaf parents and 93.3% of Deaf children of hearing parents reached or surpassed average performance levels. The study results show no significant difference between the motor development of Deaf children of Deaf parents and Deaf children of hearing parents.

Exploring physical education teachers ‘everyday understandings’ of physical literacy

ABSTRACT

In recent years, physical literacy (PL) has been the subject of increased publication, promotion, and speculation in physical education (PE). This research sought to understand how PE teachers interpret PL. We investigated teacher’s conceptualisations, understandings, practices, and ideas of ‘what’ PL stands for through a #Chat conversation with physical educators on Twitter. This generated qualitative data that were interpretively analysed. An ‘everyday philosophy’ of PL emerged from the physical educators’ relationship with the PL concept, alongside the notion that some use social media as a PL advocacy tool. A lack of sophistication was evident in the PE teachers understanding and operationalization of PL. We conclude that perhaps too much time and effort has been spent ‘adapting’ PL to national contexts, personal, and institutional agendas, rather than investing in the pedagogical and content knowledge of PE teachers to deliver on the concept of PL. We suggest that it is empirical research rather than academic opinionating that is needed to establish the validity of PL for PE.     

Real‐fiction versus historical reality: Rhetorical purification in “kent state”—the docudrama

This essay analyzes the ways in which Kent State, the made‐for‐TV docudrama, purified the image of William Knox Schroeder‐one of the four students killed on May 4, 1970, by Ohio National Guardsmen on the Kent State University campus. The author was a boyhood friend of Schroeder, his roommate at Kent State University at the time of his death, and an observer of many of the major events of the Kent State affair. This essay views the making of a docudrama as a complex problem to be solved and characterizes a docudramatist as a less‐than‐perfect decision maker. Also, this essay views Kent State as a real‐fiction through which the act of rhetorical purification was accomplished. The paper discusses the docudrama's efforts in this regard by analyzing important scenes in which inaccuracies are presented in order to achieve the purification of Schroeder's image.
