The purpose of this study is to explore humor as a factor in students’ perceptions of college teacher compliance‐gaining in the classroom. Four hundred twenty‐eight college students reported the frequency of their college teachers’ uses of compliance‐gaining tactics, the frequency of humor uses with compliance‐gaining tactics, and the effectiveness of humor used with compliance‐gaining tactics. Results revealed positive and significant relationships between humor uses and uses of particular compliance‐gaining strategies. Findings suggest that students perceive teachers to use humor more frequently with certain compliance‐gaining tactics. Moreover, students reported that certain compliance‐gaining tactics are perceived as more effective than others. 相似文献

The essay develops a theory of and models for a perspective on epistemology which may be referred to as “knowledge‐as‐status.” The perspective is intended to provide a particular conception of knowledge and a practical method for analyzing the development of and change in what we call knowledge. Toward those ends, the essay introduces the perspective, explains it as a way of understanding both the attainment of knowledge and changes in knowledge, and finally summarizes the issue of describing changes in knowledge. 相似文献

To determine what maximizes the effectiveness of on‐air promotions, as measured by ratings/share changes, this study tested a seven‐part model focusing on the structural salience of network prime‐time promos carried within other prime‐time programs. The results of analysis of more than 5,000 promos carried within 656 videotaped prime‐time hours provided consistent support for the salience model. Results showed significant changes in industry promotional practices over time and significant differences by network, genre, and the familiarity of the program to audiences. Although lead‐in ratings remained the dominant force impacting ratings for series programs (but not sporting events, movies, or specials), promotional salience variables contributed significantly to improved ratings, especially for mid‐rated continuing programs. 相似文献

This paper argues that traditional experimental methodology contributes to violating “representative validity,” defined herein as the degree to which “actual” generalizable behavior is produced in an experimental context. The importance of representative validity is discussed, and the use of the general linear model is advocated as a means of maximizing representativeness in experimental design. Six issues are discussed in connection with representative design, and the general linear model is presented as a solution to various problems which adversely affect representative validity. These issues are statistical power analysis, the use of continuous variables, unbalanced designs, non‐linearity, interactions, and random and mixed‐effects models. It is suggested that the common use of linear model techniques provides the potential for increased flexibility and encourages creative design of experimental research. 相似文献

A comparative analysis of the theories of Kenneth Burke and Alfred North Whitehead provides a different perspective of persuasion. The areas of comparison are: (1) the composition of the rhetorical situation and the function of the rhetor; (2) the modules: “identification” and “transmutation” and (3) the paradigms: “consubstantiality” and “concrescence.” Other perceptions of the rhetorical situation, the axiological latitude and functions of the rhetor, and the interrelations between the rhetor and the audience might, thereby, be gained. 相似文献

Trivializing the News? Affective Context Effects of Commercials on the Perception of Television News
This study examined whether affect induced by television commercials influences the perception of news programming. An experiment showed that viewers in positive moods generated by television commercials perceive news stories viewed both after and before watching the commercials as more entertaining, relaxing, realistic, and more credible than viewers exposed to neutral commercials do. Of interest, viewers in positive mood, as compared to neutral mood, perceived the topic presented in the news story as less important and serious. 相似文献

The effect that newspapers had on patients visiting physicians for influenza was examined for 2002 to 2008. The basis for this investigation rests on theories of media effects drawn from agenda setting, media hype, and the Social Amplification of Risk Framework. It was hypothesized that controlling for the rate of influenza, a positive relationship exists in which increases and decreases of newspaper attention to influenza precede increases and decreases in the percentage of patients visiting physicians for flu symptoms. The percentage of visits and the percentage of positive flu tests are taken from the Centers for Disease Control's flu report. Media attention was located through the Lexis/Nexis database as words per week in stories having flu in the headline in 32 newspapers. Time series analysis shows that controlling for autoregressive and seasonal effects, and the actual rate of disease present, news attention in the previous week accounts for a statistically significant portion of the increase and decrease in the number of individuals who go to their physician reporting influenza-like symptoms. Reverse causality was examined. It was shown that controlling for autoregressive and seasonal effects, patient visits did not predict news coverage, whereas the rate of the flu in the previous 3 weeks did. 相似文献

In this paper we present a number of metrics for usage of the SAO/NASA Astrophysics Data System (ADS). Since the ADS is used by the entire astronomical community, these are indicative of how the astronomical literature is used. We will show how the use of the ADS has changed both quantitatively and qualitatively. We will also show that different types of users access the system in different ways. Finally, we show how use of the ADS has evolved over the years in various regions of the world. 相似文献

With today's big data and analytics capability, access to consumer data provides competitive advantage. Analysis of consumers' transactional data helps organizations to understand customer behaviors and preferences. However, prior to capitalizing on the data, organizations ought to have effective plans for addressing consumers' privacy concerns because violation of consumer privacy brings long-term reputational damage. This paper proposes and tests a Privacy Boundary Management Model, explaining how consumers formulate and manage their privacy boundary. It also analyzes the effect of the five dimensions of privacy policy (Fair Information Practices) on privacy boundary formation to assess how customers link these dimensions to the effectiveness of privacy policy. Survey data was collected from 363 customers who have used online banking websites for a minimum of six months. Partial Least Square results showed that the validated research model accounts for high variance in perceived privacy. Four elements of the Fair Information Practice Principles (access, notice, security, and enforcement) have significant impact on perceived effectiveness of privacy policy. Perceived effectiveness in turn significantly influences perceived privacy control and perceived privacy risk. Perceived privacy control significantly influences trust and perceived privacy. Perceived privacy concern and trust also significantly influence perceived privacy. 相似文献

Research investigating relationship development through computer‐mediated channels has failed to acknowledge the importance of initial interactions. Increasingly, multimodal forms of communication, such as audio‐ and videoconferencing, in addition to text‐only formats have emerged on socially oriented websites designed for relationship initiation. Utilizing the principle of interactivity as a conceptual framework, the present study investigates whether increased structural interactivity provided by the additional aural and visual modalities influences initial interaction processes and outcomes online. The results indicate that increased availability of nonverbal modalities, combined with the valence of the information acquired, significantly affected interaction involvement and mutuality, which are markers of processual interactivity, as well as the interaction outcomes of uncertainty, predicted outcome value, and information seeking. Additional analysis revealed that mutuality mediated the effect of richness on postinteraction uncertainty level and the evaluations of future relationship potential. 相似文献

This study examined how an individual's perceived use of nonverbal immediacy is related to his or her perceived socio‐communicative style, and whether the use of nonverbal immediacy behaviors differs across relational types. Reflecting on a recent interaction, participants (N = 309) completed the Assertiveness‐Responsiveness measure (Richmond & McCroskey, 1990) and a modified version of the Nonverbal Immediacy Behaviors instrument (Richmond, Gorham, & McCroskey, 1987). Results indicate that (a) competent communicators differ from noncompetent, submissive, and aggressive communicators across ten nonverbal immediacy behaviors and (b) the use of nonverbal immediacy behaviors differs across relational types. 相似文献
