Hitting promotion hard: A network response to channel surfing and new competition     

Susan Tyler Eastman  Gregory D. Newton 《Journal of Applied Communication Research》2013,41(1):73-85

Examination of over 600 on‐air promos carried within or adjacent to situation comedies showed that the promos’ salience impacted the ratings of the promoted program. After controlling for the ratings of the lead‐in to the promoted program, significant associations were found for the method of construction of the promo, the familiarity of the promoted program, the amount of clutter within breaks, the position of the promo within the break, and the rating of the program carrying the promotion. The results suggested a six‐part model for maximizing the effectiveness of on‐air promotion.  相似文献   

How Promotional Content Changes Ratings: The Impact of Appeals,Humor, and Presentation     

Susan Tyler Eastman  Gregory D. Newton  Paul D. Bolls 《Journal of Applied Communication Research》2013,41(3):238-259

This study assessed the impact of content--as opposed to structural--factors on television program ratings, seeking to locate clusters of components that would identify effective on-air promotion and allocate content a better-defined place within theoretic models of media priming. Stepwise multiple regression analyses of 1,547 on-air promos for 155 prime-time programs demonstrated that 5-9% of ratings variance was accounted for by content appeals, humor, and presentation in promos for comedy programs. The influence of content variables was greater for familiar than unfamiliar comedies, and humor and presentation in promos contributed to variance in ratings for mid-rated but not high- or low-rated comedies.  相似文献   

The Significance of Physical Education Content: “Sending the Message” in Physical Education Teacher Education     

Tyler G. Johnson 《Quest (Human Kinetics)》2013,65(3):187-196

Mind-body dualism has likely influenced how many view human beings and their behavior—mind (i.e., thinking) is elevated over body (i.e., performing)—even in Physical Education Teacher Education. The problem is that such a perspective makes physical education content (i.e., dance, games, play, and sport) subsidiary to more “intellectual” or “academic” content. This article invites Physical Education Teacher Education faculty to consider how to effectively “send the message” to future physical educators that physical education content is valuable and respectable and in many ways epitomizes intelligent human behavior. Specifically, Physical Education Teacher Education faculty are invited to (a) challenge traditional definitions of intelligence and introduce alternative definitions, (b) participate regularly in their own playgrounds, (c) provide a sufficient dose of activity courses in their curricula, (d) teach activity courses, (e) establish a performance-oriented culture, and (f) administer performance and/or game play evaluations.  相似文献   

Evolution in the Caribbean Classroom: A critical analysis of the role of biology teachers and science standards in shaping evolution instruction in Belize     

Elvis Enrique Nunez  Rose M. Pringle  Kevin Tyler Showalter 《International Journal of Science Education》2013,35(15):2421-2453

A survey of the literature on evolution instruction provides evidence that teachers’ personal views and understandings can shape instructional approaches and content delivered in science classrooms regardless of established science standards. This study is the first to quantify evolutionary worldviews of in-service teachers in the Caribbean, specifically in Belize, an English-speaking nation with a high school system guided by a regional biology syllabus and strict standardized tests. Using the Measure of Acceptance of the Theory of Evolution (MATE) instrument and knowledge test, we investigated (1) the current level of acceptance and understanding of evolution as given by 97% of high school biology teachers in Belize; (2) the factors associated with acceptance and understanding of evolutionary theory. With an average MATE score of 64.4 and a mean knowledge score of 47.9%, Belizean teachers were classified as having both ‘Low Acceptance’ and ‘Low Understanding’ of evolutionary theory. A positive correlation was found between teacher acceptance and understanding of evolution. A review of the Caribbean Secondary Examination Certificate biology syllabus suggests that evolution plays a minimal role in the high school biology classroom. We believe that Belize presents a unique opening for future training on evolution instruction since 57% of the biology teachers self-proclaim to be unprepared to teach evolution. The results of this study have implications for policy, practice and research with teachers’ acceptance, understanding and confidence in teaching evolution serving as important predictors for instructional approaches used in the biology classroom.  相似文献   

Differences in technique between sprinters and distance runners at equal and maximal speeds     

Tyler Bushnell 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(3):261-268

In the finishing kick of a distance race, maximizing speed becomes the focus even if economy may be sacrificed. If distance runners knew how to alter their technique to become more sprint-like, this process could be more successful. In this study, we compared the differences in technique between sprinters and distance runners while running at equal and maximal speeds. Athletes consisted of 10 Division I distance runners, 10 Division I sprinters, and 10 healthy non-runners. They performed two tests, each consisting of a 60-m run on the track: Test 1 at a set pace of 5.81 m/s, while Test 2 was maximal speed. Video was collected at 180 Hz. Significant differences (P < 0.05) between the sprint and distance groups at maximal speeds were found in the following areas: speed, minimum hip angle, knee extension at toe-off, stride length, contact time, and recovery knee at touchdown. In Test 1, sprinters and distance runners displayed many of the same significant differences. The control group was similar to the distance group in both trials. As distance runners attempt to sprint, the desired adjustments do not necessarily occur. Distance runners may benefit from biomechanical interventions to improve running speed near the end of a race.  相似文献

Understanding Heterogeneity in the Impact of Public Preschool Programs

We examine the North Carolina Pre-K (NC Pre-K) program to test the hypothesis that observed variation in effects resulting from exposure to the program can be attributed to interactions with other environmental factors that occur before, during, or after the pre-k year. We examine student outcomes in 5th grade and test interaction effects between NC's level of investment in public pre-k and moderating factors. Our main sample includes the population of children born in North Carolina between 1987 and 2005 who later attended a public school in that state, had valid achievement data in 5th grade, and could be matched by administrative record review (n = 1,207,576; 58% White non-Hispanic, 29% Black non-Hispanic, 7% Hispanic, 6% multiracial and Other race/ethnicity). Analyses were based on a natural experiment leveraging variation in county-level funding for NC Pre-K across NC counties during each of the years the state scaled up the program. Exposure to NC Pre-K funding was defined as the per-4-year-old-child state allocation of funds to a county in a year. Regression models included child-level and county-level covariates and county and year fixed effects. Estimates indicate that a child's exposure to higher NC Pre-K funding was positively associated with that child's academic achievement 6 years later. We found no effect on special education placement or grade retention. NC Pre-K funding effects on achievement were positive for all subgroups tested, and statistically significant for most. However, they were larger for children exposed to more disadvantaged environments either before or after the pre-k experience, consistent with a compensatory model where pre-k provides a buffer against the adverse effects of prior negative environmental experiences and protection against the effects of future adverse experiences. In addition, the effect of NC Pre-K funding on achievement remained positive across most environments, supporting an additive effects model. In contrast, few findings supported a dynamic complementarity model. Instrumental variables analyses incorporating a child's NC Pre-K enrollment status indicate that program attendance increased average 5th grade achievement by approximately 20% of a standard deviation, and impacts were largest for children who were Hispanic or whose mothers had less than a high school education. Implications for the future of pre-k scale-up and developmental theory are discussed.  相似文献   

Enhancing Communication Interventions and Evaluations through Communication Design     

Tyler R. Harrison 《Journal of Applied Communication Research》2014,42(2):135-149

Communication design is first and foremost about creating, engineering, or critiquing approaches to communication that achieve specific goals or values. A design approach acts as an integrative perspective for finding the relevance of theory to a specific site of intervention. Communication design processes are illustrated through work on ombuds processes and organ donation campaigns. This research highlights four propositions related to communication design. First, design should be about both creation and critique. Second, design is complementary to, and strengthens, theory (and vice versa). Third, design can be both unique to an intervention or context and iterative from previous designs. Finally, design helps us uncover unexpected and unintended consequences, uncovering hidden properties of communication and leading to opportunities for modifying and correcting communication practices. These unintended consequences and other design successes and failures provide opportunities for learning and creating better systems. In these ways, a commitment to design processes strengthens both our research and our practice of communication across a variety of communication contexts and across different levels of communication.  相似文献

The Reconciliation of Art and Psychology     

Tyler E. Freeman 《The International Journal of Art & Design Education》2014,33(2):184-194

The disciplines of art and experimental psychology share a number of interesting areas of overlap which are unknown and/or unconsidered by many. This purpose of this article is to elucidate topics that are of interest to both artists and psychologists in an attempt to encourage interdisciplinary collaborations. It is only on rare occasions that artists and psychologists engage in collaborative research efforts, however; here I discuss a number of topics in psychology (e.g. attention, expertise, object perception and mental representations) that would be of interest to both disciplines. The concepts that are often taught in the art studio can provide unique insight into perceptual processes that play a role in the creation and evaluation of art. However, collaborative research efforts are necessary better to understand these perceptual processes. Thus, the product of collaborative research in such areas can inform art education and psychology to mutual benefit. This article discusses topics of interest for art and psychology and poses possible research questions that can be investigated via artist–psychologist collaborations.  相似文献
