Few studies have examined the impact of an increased physical demand on batting performance, especially over extended periods of play. Therefore, the purpose of this study was to determine the physiological and perceptual responses of batsmen scoring a simulated limited overs century, and to link these to sprint times and accuracy of the impact of the ball on the bat. Seventeen male, university level cricketers, performed a batting protocol (BATEX©), typical of a limited overs century. The protocol consisted of six stages, each of five overs, with each stage matched to a specific phase of play. Throughout the protocol heart rate (HR), central ratings of perceived effort (RPE), sprint times and impact accuracy were recorded. HR fluctuated as a function of exercise intensity (124.16–159.61?bpm). Central RPE increased as a function of intensity and duration (11.87–16.04). Sprint times got slower over time (5.67–5.81?s), while impact accuracy improved significantly (p?.05) after stage one and then plateaued for the remainder of the protocol (64.81–57.39?mm). In conclusion, the protocol significantly impacted cardiac strain and perceptual responses negatively impacting sprint times with an improvement in batting accuracy. 相似文献

Our study was motivated by the fact that, despite the increasing pervasiveness of political advertising in the political process of many democracies, little empirical research has been conducted to unveil common patterns or crucial differences of political spots across cultural boundaries. Our study thus provided one opportunity to gain better understanding and insights into how media phenomena are related to cultural orientation by comparing and contrasting the content of political spots across the United States and South Korea. In particular, this study analyzed verbal components of political spots in both US and Korean presidential elections over the past 20 years. To the extent that clear differences exist between American and Korean cultural patterns, political spots, which are a conspicuous indicator of cultural values, appear to manifest these differences quite strongly. The findings of this study provide evidence that political advertising primarily reflects the uniqueness of indigenous cultures. 相似文献

This paper examines the preservation and curatorial approaches explored for the exhibition Silent Explosion: Ivor Davies and Destruction in Art at Amgueddfa Cymru – National Museum Wales (November 2015–March 2016). The collaboration between the artist, curator/researcher, and conservators is considered and the evolving and flexible way in which transient pieces were presented/re-presented is described. The paper offers a case study in the context of this exhibition and argues that regardless of whether it is in traditional media (such as painting) or as time-based media (unstable and open to interpretation), Davies' work challenges a perception of artworks as finished, single-authored objects. 相似文献

Writing at a time when applications of Total Quality Management (TQM) in higher education in the United States are in great vogue, the author reminds the reader that TQM is only one of many management strategies that over the years have had their periods of popularity. Strategies come and go. Usually a hot strategy is in vogue for no more than seven years; then other ideas come into vogue as other ways of getting the quick fix are tried. Other strategies in competition with TQM in the United States include outcomes assessment, Deming's fourteen points, the Malcolm Baldridge Award, the ISO 9000 series, restructuring, re‐engineering, and performance indicators. American higher education institutions will probably have recourse to more traditional models than TQM for creating change in the future. 相似文献

This study investigated how newspapers adopted partisan branding as a product differentiation strategy under pressure of intense market competition, through cases of conservative dailies in South Korea. Despite academic interest in news media's partisanship, only a few studies attempted to conduct analysis at the organizational level. Drawing on the hierarchy of influences model as a main theoretical framework, the present study examined how partisanship of newspapers was related to the social and economic forces. Evidence demonstrated that conservative bias increased as market competition intensified. Conservative bias was positively associated with the ideological mood of the conservative group, and the revenue decreased as conservative newspapers carried stronger conservative bias. These results will add insight into the prevalence of partisanship in today's media environment. 相似文献

This article describes a conceptual analysis of user-generated tags applied to video games in the Steam video game distribution system. The research team scraped all user-generated tags available on Steam and then conducted a conceptual analysis of the tags, sorting them into categories and comparing them to the current version of the Video Game Metadata Schema. This analysis allowed the team to identify new metadata elements and terms useful to game players. We present a discussion covering the major issues in organizing the terms, as well as the implications for the future work in the area of video game metadata. 相似文献

This article describes the process designed to systematically weed two community college library reference collections in preparation for potential funding of a learning commons space. The author explains the methodology used to help facilitate the reassessment of nearly 10,000 reference titles by librarian liaisons. The goal of the project was to consistently capture each title’s weeding status designation along with required bibliographic data while stopping short of executing the weeding itself. Details about the process and consequences of the resulting category breakdowns are described in detail. The article lists key success factors such as working with teams from different departments to help manage the day-to-day procedures. Practical suggestions are offered about the use of collaborative tools, about methods for transmitting support data to liaison librarians to enable quick decisions, about goal setting, and about establishing consistent means of data collection. 相似文献

Ice hockey body checks involving direct shoulder-to-head contact frequently result in head injury. In the current study, we examined the effect of shoulder pad style on the likelihood of head injury from a shoulder-to-head check. Shoulder-to-head body checks were simulated by swinging a modified Hybrid-III anthropomorphic test device (ATD) with and without shoulder pads into a stationary Hybrid-III ATD at 21 km/h. Tests were conducted with three different styles of shoulder pads (traditional, integrated and tethered) and without shoulder pads for the purpose of control. Head response kinematics for the stationary ATD were measured. Compared to the case of no shoulder pads, the three different pad styles significantly (p < 0.05) reduced peak resultant linear head accelerations of the stationary ATD by 35–56%. The integrated shoulder pads reduced linear head accelerations by an additional 18–21% beyond the other two styles of shoulder pads. The data presented here suggest that shoulder pads can be designed to help protect the head of the struck player in a shoulder-to-head check. 相似文献

We compared SenseWear Armband versions (v) 2.2 and 5.2 for estimating energy expenditure in healthy adults. Thirty-four adults (26 women), 30.1 ± 8.7 years old, performed two trials that included light-, moderate- and vigorous-intensity activities: (1) structured routine: seven activities performed for 8-min each, with 4-min of rest between activities; (2) semi-structured routine: 12 activities performed for 5-min each, with no rest between activities. Energy expenditure was measured by indirect calorimetry and predicted using SenseWear v2.2 and v5.2. Compared to indirect calorimetry (297.8 ± 54.2 kcal), the total energy expenditure was overestimated (P < 0.05) by both SenseWear v2.2 (355.6 ± 64.3 kcal) and v5.2 (342.6 ± 63.8 kcal) during the structured routine. During the semi-structured routine, the total energy expenditure for SenseWear v5.2 (275.2 ± 63.0 kcal) was not different than indirect calorimetry (262.8 ± 52.9 kcal), and both were lower (P < 0.05) than v2.2 (312.2 ± 74.5 kcal). The average mean absolute per cent error was lower for the SenseWear v5.2 than for v2.2 (P < 0.001). SenseWear v5.2 improved energy expenditure estimation for some activities (sweeping, loading/unloading boxes, walking), but produced larger errors for others (cycling, rowing). Although both algorithms overestimated energy expenditure as well as time spent in moderate-intensity physical activity (P < 0.05), v5.2 offered better estimates than v2.2. 相似文献
