An important area of applied communication research is teachers’ use of classroom discipline and management strategies which have become known as Behavior Alteration Techniques (BATs). The instrument commonly used to measure teachers’ use of BATs is the checklist of Behavior Alteration Techniques. The purpose of the present research was to assess the convergent validity of the checklist of Behavior Alteration Techniques. Thus, this research attempted to assess the extent to which teachers’ likelihood‐of‐use ratings converge with other measures of teacher BAT use. It was hypothesized that the correlation between students’ and student teachers’ ratings of the frequency of teacher BAT use would be significantly higher than the correlation of either index with teachers’ likelihood‐of‐use ratings. This hypothesis was not supported: The BATs checklist did not fail this test of convergent validity. However, the results do not support the claim that the BATs checklist passed this test of convergent validity. Explanations for these results are offered and their implications are discussed. In brief, the present results suggest important considerations in the study of this important area of applied communication.  相似文献

This study assessed the discriminant validity of the checklist of Behavior Alteration Techniques. Specifically, the ability of the BATs checklist procedure to discriminate between the likelihood that individual BATs would be selected and the social desirability of those same BATs was examined. The BATs checklist should discriminate between the likelihood that individual BATs would be selected and the social desirability of those same BATs because 50 years of observational studies of teacher discipline behavior suggest that teachers typically and routinely employ negative and antisocial strategies to correct student misbehavior (Burleson & Waltman, 1993). In a within‐subject, repeated measures designs, prospective teachers and experienced teachers provided likelihood‐of‐use and social appropriateness ratings to the BATs checklist in the four hypothetical situations typically employed with the BATs checklist. As predicted, likelihood‐of‐use and social appropriateness ratings were significantly correlated. Thus, the BATs checklist is not able to discriminate between the likelihood that BATs would be used and the social appropriateness of those BATs. As Campbell and Fiske (1959) have argued, an instrument's discriminant validity is a minimum standard that social scientific instruments must meet.  相似文献

The purpose of this study was to further investigate the effectiveness of speech evaluation procedures and measures. Specifically, this study examines the relationship between rater training and evaluation fidelity— a concept which focuses on the shared understanding of meaning between speech raters and students in terms of what is expected and what is performed. To do so, two studies were conducted. Study one hypothesized that evaluation fidelity would be associated with rater training such that inter‐rater (instructor‐instructor) reliability would be higher after training. The findings suggest that participants in Study one increased their evaluation fidelity in terms of total scores. The variance and frequency reports confirmed that the range of scores decreased (higher evaluation fidelity) after training. Study two hypothesized that instructors who provided their students with training in using the “Criteria for Evaluating Speeches” form would achieve higher evaluation fidelity than those instructors who do not. Results support this hypothesis and reveal higher evaluation fidelity between instructors and students in the group where students received a copy and explanation of the criterion‐based assessment tool.  相似文献

This research attempted to develop a multidimensional measure of parasocial interaction. A 47‐item questionnaire derived from qualitative responses was submitted to principal components analysis ‐ resulting in a 22‐item, four‐factor Audience Persona Interaction (API) Scale. The four sub‐scales were: Identification with Favorite character, Interest in Favorite character, Group Identification/Interaction, and Favorite Character's Problem Solving Ability. In the initial analysis, the index and it's subscales were found to be very reliable and positively correlated to program exposure level. In an additional construct validity test, mild linear relationships were found between PSI ‐as measured by the API Scale ‐ and viewing level.  相似文献

An investigation of memorable messages as guides to self‐assessment of daily behavior was conducted. Respondents were asked to keep diaries for five days. Each day participants were asked to recall one behavior that violated and one behavior that exceeded their personal expectations for themselves. After recalling the situation, participants were asked to recall the memorable messages, if any, which came to mind when self‐assessing these behaviors. This method used the self‐assessment of prior behavior as the entry point to a feedback loop. Control theory predicts that within the feedback loop behaviors are compared with internal principles that come from memorable messages. This comparison is predicted to result in either a positively or negatively valenced evaluation of the behavior if it either exceeds or violates personal standards represented as internal principles. The findings include the categories of behaviors that exceeded or violated personal expectations, the memorable messages, and the primary sources of the memorable messages that were recalled during the comparison process. In addition, comparisons were made between this research effort and a previous study that asked participants to self‐assess more extreme cases of behavior and the memorable messages associated with that process.  相似文献

Although American broadcasters are conscious of the role of the North American Regional Broadcasting Agreement, it may well be that few realize the existence of other regional broadcasting agreements and bodies, with different functions, and cast into a different mold. One such body is the International Radio and Television Organization (OIRT) which coordinates the broadcast activities of nations within or allied in varying degree to the sphere of influence of the USSR.  相似文献

Quantitatively oriented researchers differ in how they report the results of tests of statistical significance. Some authors report statistically significant results as less than an alpha level (e.g., p < .05), while others report exact p‐values (p = .04) from statistical software readouts. This paper argues that three reporting errors are possible when p‐values are reported based on computer readouts. First, the p‐value of obtained data can never be equal to, or less than, zero. Thus, reporting that a finding is p = .000 is an error. Second, rounding down errors can lead to factual inaccuracies. For example, it is inaccurate to report a p = .052 as p < .05. Finally, p‐values for wrong‐direction effects with one‐tailed tests must always be p> .50. Awareness of these issues should facilitate accurate statistical reporting.  相似文献

Guidelines are specified in this article for developing video‐taped informative speech models. Faculty members rated selected video‐taped informative speeches on nine variables and two months later rated nine of the same speeches again. The faculty judges were reliable on their ratings for eight of the nine variables rated during the two sessions. Five of the nine speeches were identified as being representative of one of three significantly different levels of excellence.  相似文献

The knowledge production provided by universities is essential to sustaining a country’s long-term economic growth and international competitiveness. Many nations are thus driving to create sustainable and effective funding environments. The evaluation of university knowledge, productivity and research quality becomes critical, with ever increasing share of public funding allocated on the basis of research assessment exercises. Nevertheless, the existing methods to assess the universities’ knowledge production are often affected by limits and biases, extensively discussed in the scientific literature.In this paper we study how to reduce the effect of size-related bias due to university size on the indicators of knowledge performance used in evaluation exercises. We propose an innovative utilization of the scale-free property of the power laws as a scaling relationship, to normalize research productivity indicators, and provide results independent by the university size. Our method has evident policy implications and gives a contribution for the future design of assessment exercises.We apply our findings in a recent Italian research assessment exercise.  相似文献

The study explores the publication trends of scholarly journal articles in two core Library and Information Science (LIS) journals indexed under ScienceDirect Database during the period for the period 2000–2010, and for the “Top 25 Hottest Papers” for 2006–2010. It examines and presents an analysis of 1000 research papers in the area of LIS published in two journals: The International Information & Library Review (IILR) and Library & Information Science Research (LISR). The study examines the content of the journals, including growth of the literature, authorship patterns, geographical distributions of authors, distribution of papers by journal, citation pattern, ranking pattern, length of articles, and most cited authors. Collaboration was calculated using Subramanyam's formula, and Lotka's law was used to identify authors' productivity. The results indicated that authors' distributions did not follow Lotka's law. The study identified the eight most productive authors with a high of 19 publications in this field. The findings indicate that these publications experienced rapid and exponential growth in literature production. The contributions by scientists from India are examined.  相似文献

While relational maintenance has been found to be an important aspect of interpersonal relationships within the face‐to‐face world, the nature of relational maintenance among partners within computer‐mediated relationships is a relatively unexplored area. This study examined the use of maintenance strategies and perceptions of relational partners among (N = 178) undergraduate students within exclusively Internet‐based and primarily Internet‐based relationships. The findings indicated that positivity and openness were the most frequently used maintenance strategies. People who used positivity and on‐line activities had higher perceptions of attitude similarity than people using avoidance strategies, and people who used positivity and openness perceived their partner's quality of communication to be higher than those who used other strategies. People maintaining primarily Internet‐based relationships had higher relational communication and background similarity scores than people maintaining exclusively Internet‐based relationships. Finally, people maintaining exclusively Internet‐based relationships had different perceptions of on‐line friends and acquaintances based upon their frequency of on‐line interaction.  相似文献

This article extends Stratford's brief observations about the problematic status of racial and ethnic group statistics to a discussion of the relationship among these statistics, public policy, and the conceptual status of race and ethnicity. Federal statistics are organizational products that are socially constructed. They represent the implementation of public policies that govern political, social, and economic life. It is the interaction between politics and the subjective meaning of race and ethnicity that is responsible for the continual modification of racial and ethnic group statistics. The article discusses the premises on which racial and ethnic group statistics have been based and illustrates how they were implemented in the instructions of the decennial censuses for classifying the race and ethnicity of the population. The article then summarizes some of the empirical evidence from recent research conducted by federal agencies and social scientists to show that racial and ethnic group statistics produced by government record keeping systems have no objective status. The meaning of race and ethnicity is contextual, situational, and subjective, and, thus, how respondents and observers define these concepts has significant consequences for the quality of federal statistics.  相似文献

Abstract

Even though e‐commerce almost disappeared from public discussion, it still assumes a vital role in the strategic management of most enterprises. New entry in e‐commerce, whether as a new business segment of an established company or as a new enterprise, is likely to deal with the liabilities of size and newness. The aim of this paper it to discuss if those factors have an impact on the implementation and success of B2C e‐commerce. We chose the online book market as our reference market and drew a random sample of retailers and publishers with an online shop. The quality of the web presence, indirect success (number of links to a particular site) and direct success (turnover of the web shop) were compared in subsamples constructed by the use of median splits according to age and size. Younger companies and larger companies were found to have a web presence of higher quality and were more successful than older or smaller companies. We conclude that the liabilities of newness do not seem to have an adverse performance impact in e‐commerce. However, when a market entry is considered, new players must ensure that they can commit enough resources to build a high quality web presence.  相似文献

A review of extant research evidence indicates that when source identification is delayed until after the message has been presented, the differential effectiveness of high‐ and low‐credibility communicators is reduced. In particular, those combinations of credibility level and advocated position that are ordinarily (i.e., with pre‐message identification) relatively advantageous (a low‐credibility source with a proattitudinal position, or a high‐credibility source with a non‐proattitudinal position) have persuasive effectiveness reduced by delayed identification, whereas those combinations that are ordinarily relatively disadvantageous (a high‐credibility source with a proattitudinal position, or a low‐credibility source with a non‐proattitudinal position) enjoy enhanced effectiveness with delayed identification. The magnitude of the effects associated with identification‐timing variations is quite large (mean absolute value of d = .753), at least by comparison to other factors for which quantitative estimates of persuasive effect are available. The observed effects place constraints on explanations of credibility's effects; in particular, credibility's effects cannot be explained through the mere association of a given communicator with a particular position.  相似文献

This essay is a review of four projects that use meta‐analysis to summarize existing research on four behavioral issues for HIV/AIDS education and prevention. The first project considers the importance of behavioral routines to promote safer sex behavior and the need to consider how the gender of the participant impact on those discussions. The second project examines four issues (disclosure, social support, risk behavior, and childbearing) for those testing positive for HIV. The third project examines the impact that the announcement of Earvin “Magic”; Johnson on behaviors and attitudes of adults and children. The final project examines the difference in knowledge for one subgroup of U.S. society (Hispanics) compared to either White European or African Americans. The summaries of ongoing projects illustrate the importance of meta‐analysis as a means to aggregate existing research.  相似文献

This study addresses three types of sex differences in relational communication. Male and female respondents completed an assessment of gender‐role measuring agency and communion and read four scenarios with messages attributed to male and female sources. Respondents rated the relational dimensions of affiliation and dominance. Female sources are judged higher in affiliation. Sex and agency interact with situation for perceptions of affiliation. Situation and communion affect judgments of dominance. Individuals higher in communion perceive less dominance. The results provide insight into dominance and affiliation as competing frames for interpreting situations.  相似文献
