In this study, we examined the impact of a male opponent's pre-match body language and clothing (general vs. sports-specific) on how his performances were judged by an observer. Forty male tennis players viewed videos of a male target tennis player warming up and then observed playing footage of the target. Each participant viewed the target player warming up displaying one of four combinations of body language and clothing (positive body language/tennis-specific clothing; positive body language/general sportswear; negative body language/tennis-specific clothing; negative body language/general sportswear). Participants rated the performance of the tennis player and gave their perceptions of the likely outcome of a tennis match with the target player. Analyses of variance indicated that clothing and body language had an interactive effect on both outcome expectations and ratings of performance. The findings support the contention that the initial impressions athletes form of their opponents can influence the way in which they judge the performances of opponents and their perceived likelihood of success against the same opponents.  相似文献   

Design Principles for Augmented Reality Learning     

Matt Dunleavy 《TechTrends》2014,58(1):28-34

Augmented reality is an emerging technology that utilizes mobile, context-aware devices (e.g., smartphones, tablets) that enable participants to interact with digital information embedded within the physical environment. This overview of design principles focuses on specific strategies that instructional designers can use to develop AR learning experiences. A review of the literature reveals the following three design principles as instructive: 1. Enable and then challenge (challenge): 2. Drive by gamified story (fantasy); and 3. See the unseen (curiosity). These design principles can also be viewed as an attempt to either leverage the unique affor- dances of AR or minimize the limitations of the medium as reported in the literature (Dunleavy & Dede, 2014). As the field matures and more research teams explore the potential of AR to enhance teaching and learning, it will be critical to determine the design techniques that optimize the unique affordances of AR, minimize the limitations of the medium, and ultimately enhance learning across the curriculum.  相似文献   

罗宾·威廉姆斯:白天不懂夜的黑     

Matt Zoller Seitz  Mac 《英语辅导》2014,(11):4-9

罗宾·威廉姆斯的离世突然而毫无预兆。或者说,在世人眼中,他不应该以这种方式突然离开人们的视线。我们只记得他欢乐的模样,哪怕在严肃的剧情片或是晦暗不明的惊悚片,我们也期待他有那么一两句幽默台词能引得观众捧腹大笑。所以我们不断发问:他看上去那么乐观开朗、没心没肺,怎会以自杀的方式了却自己的一生呢?殊不知镁光灯之外的他,终生与酒精、毒品以及抑郁症纠缠,台上的欢笑不过是他的职业需求,嘴角牵扯的笑容根本没有到达眼底  相似文献   

Citation bias in otolaryngology systematic reviews     

Matt Vassar  Austin L. Johnson  Adriana Sharp  Cole Wayant 《Journal of the Medical Library Association》2021,109(1):62

Objective:Reproducibility of systemic reviews (SRs) can be hindered by the presence of citation bias. Citation bias may occur when authors of SRs conduct hand-searches of included study reference lists to identify additional studies. Such a practice may lead to exaggerated SR summary effects. The purpose of this paper is to examine the prevalence of hand-searching reference lists in otolaryngology SRs.Methods:The authors searched for systematic reviews published in eight clinical otolaryngology journals using the Cochrane Library and PubMed, with the date parameter of January 1, 2008, to December 31, 2017. Two independent authors worked separately to extract data from each SR for the following elements: whether reference lists were hand-searched, other kinds of supplemental searching, PRISMA adherence, and funding source. Following extraction, the investigators met to review discrepancies and achieve consensus.Results:A total of 539 systemic reviews, 502 from clinical journals and 37 from the Cochrane library, were identified. Of those SRs, 72.4% (390/539) hand-searched reference lists, including 97.3% (36/37) of Cochrane reviews. For 228 (58.5%) of the SRs that hand-searched reference lists, no other supplemental search (e.g., search of trial registries) was conducted.Conclusions:These findings indicate that hand-searching reference lists is a common practice in otolaryngology SRs. Moreover, a majority of studies at risk of citation bias did not attempt to mitigate the bias by conducting additional supplemental searches. The implication is that summary effects in otolaryngology systematic reviews may be biased toward statistically significant findings.  相似文献

The Commodity Flow of U.S. Children's Television     

J. Matt Giglio 《Critical Studies in Media Communication》2013,30(1):26-44

This article argues that commodity flow is a defining characteristic of children's television programming, and that this flow of commodity and corporate-brand images builds into the genre a relatively coherent selling ethos. Three-hour blocks of programming, recorded on two different Saturday mornings for several broadcast and cable networks, were analyzed to highlight commodity flow within and between networks. This flow of commodities on children's television indicates a blurring of the distinction between content and promotional forms and illustrates the high level of commercialism targeted at this audience.  相似文献   

Institutions for Civic Technoscience: How Critical Making is Transforming Environmental Research     

Sara Ann Wylie  Kirk Jalbert  Shannon Dosemagen  Matt Ratto 《The Information Society》2014,30(2):116-126

This article explores the changing relationship between the academy and new public formations of scientific research, which we term “civic technoscience.” Civic technoscience leverages tactics seen in critical making communities to question and transform how and who can make credible and actionable knowledge. A comparison of two case studies is used. The first is a grassroots mapping process that allows communities to generate high-quality aerial imagery. The second is an academic-led project using environmental sensors to engage disparate audiences in scientific practice. These two projects were found to differ in their ability to form strategic spaces for community-based science, and suggest pathways to foster more robust relationships across the public–academic divide. By altering power dynamics in material, literary, and social technologies used for scientific research, we argue that civic technoscience enables citizens to question expert knowledge production through critical making tactics, and creates opportunities to generate credible public science.  相似文献   

Differences Across Majors in the Desire to Obtain a License to Carry a Concealed Handgun on Campus: Implications for Criminal Justice Education     

Jeffrey A. Bouffard  Matt R. Nobles  William Wells 《Journal of Criminal Justice Education》2013,24(3):283-306

The current study examines whether students' course of study is related to their desire to carry a concealed handgun on campus. This analysis is motivated by a growing number of studies that have explored differences between criminal justice (CJ) and other majors in the areas of personality, attitudes, values, and career expectations, and also by discussions of the issue of concealed handguns on campuses following recent shootings on college campuses. Using data from over 3,100 students who completed an online survey instrument, results revealed that CJ majors were in fact more interested in carrying a legally concealed handgun on campus, if it were allowed by university policies. These results held even when controlling for other significant predictors of the desire to carry a concealed handgun. Implications for CJ education and the wider debate about concealed weapons on university campuses are discussed.  相似文献   

Influencing the College Attendance Rates of Hispanics in Texas     

Brent D. Cejda  Matt Short 《Community College Journal of Research & Practice》2013,37(4-6):347-361

A number of policymakers have shifted their attention from the participation rates of Hispanics in postsecondary education to the percentage of this population that completes a baccalaureate degree. Several reports stress that while participation rates have increased, there are continued disparities in outcomes between Hispanic and White college students (President's Advisory Commission on Educational Excellence for Hispanic Americans, 2003 President's Advisory Commission on Educational Excellence for Hispanic Americans . ( 2003 ). From risk to opportunity: Fulfilling the educational needs of Hispanic Americans in the 21st Century . Washington , DC : Author .

Although many states have experienced increases in Hispanic postsecondary attendance, such is not the case in Texas—a state with one of the largest Hispanic populations in the country. Figures for 2003 show that 3.9% of Hispanics in Texas were enrolled in some type of postsecondary institution compared to 5.2% of African Americans and 5.6% of Caucasians (Haurwitz, 2005 Haurwitz , R.
