Tomasello, Carpenter, and Liszkowski (2007) present compelling data to support the view that infant pointing, from the outset, is communicative and deployed in many of the same situations in which adults would ordinarily point for one another, either to share their interest in something, or to informatively help the other person. This commentary concurs with the view that infant pointing is a communicative gesture, but challenges their interpretation of the motives behind pointing in 12-month-olds. An alternative account is proposed, according to which infant pointing is neither declarative nor imperative, but interrogative, and rather than being driven by the motive to share or help, it may serve a powerful cultural learning mechanism by which infants can obtain information from knowledgeable adults. 相似文献

Research reported in this paper investigates the reconceptualization (McCroskey, 1984) of communication apprehension (CA), focusing on the relationship between context‐CA and state‐CA. The validity of the reconceptualization can be enhanced by demonstrating that state‐CA (level of fear and anxiety) is systematically related to context‐CA (predisposition). Two research studies using a new operational measures of state‐CA and context‐CA, the Communication Anxiety Inventory, offer empirical support for the relationship between context‐CA and state‐CA. Results show that context‐CA explains a minimum of 50% of the state‐CA variance. Conclusions suggest that level of fear or anxiety varies closely with context‐CA and that the new scales have strong predictive validity. 相似文献

It was the purpose of the present study to measure the effects of an intercultural communication workshop (ICW) on American participants’ intercultural communication competence. This study utilized the behavior observation methodology developed by Ruben (1976) with the contrast‐American simulation technique developed by Stewart (1966) to investigate intercultural communication competence development. Using a nonequivalent control group design, a structured communication event employing the contrast‐American technique was developed in which each subject discussed the topic of leadership communication with a contrast‐American at two intervals (pretest and posttest) and these interactions were videotaped. Two judges then viewed the videotaped interactions and rated the subjects’ intercultural communication competence using behavioral observation measures. The results suggest that (I) behavioral observation methodology can be reliably employed to assess intercultural communication competence and (2) the ICW did not significantly improve the American participants’ intercultural communication competence. These findings are discussed in terms of intercultural education/training and suggestions for future research on the ICW are presented. 相似文献

INTRODUCTION According to yearly statistics the demand for multimedia traffic over computer networks is con- stantly on the increase (Nielsen//NetRatings, http:// www.nielsen-netratings.com/). Therefore, it is inevi- table that situations where different media streams will need to share communication resources will be- come commonplace. In such cases, it would be of interest to optimize the overall performance of the network. In other words, resources should be allo- cated across the com… 相似文献

The objective of this study was to investigate graduate students' perceptions of their graduate advisors' communication (competence, credibility, and nonverbal immediacy), and how these perceptions impact advisees' perceptions of learning, effectiveness of the advisee‐advisor relationship, and advisors' degrees of mentoring. Advisee perceptions of her or his advisor's competence and caring/goodwill accounted for 43% of the variance in advisee cognitive learning. Advisee perceptions of her or his advisor's caring/ goodwill accounted for 39% of the variance in advisee perceptions of the effectiveness of the advisee‐advisor relationship. Lastly, this study noted that the linear combination of advisee perceptions of advisor credibility and communication competence accounted for 55% of the variance in an advisee's perception of the amount of mentoring an advisee received from her or his graduate advisor. 相似文献

Summary In these two articles we have proposed a schematic theoretical model for the study of communication, one which subsumes both
face-to-face and mass communication but is intended as an orientation to a general theory of mass communication. In addition
we have used the model as a framework for a review of a part of the literature of mass communication and have attempted a
brief assessment of the present state of our knowledge of the field.
This paper presents one application of the authors’ conceptual model of the communication process published in the last issue
of AVCR. Here they are attempting to order the existing research findings on “fortuitous” communication in relationship to
their model. Malcolm S. MacLean, Jr., and Bruce H. Westley are assistant professors of Journalism, The University of Wisconsin. 相似文献

Nearly 700 US journalism and mass communication faculty (all teaching personnel) reported their perceptions of student email use via a web‐based survey. This nationwide study focused on the content of email sent by faculty to students, email’s effectiveness, and email’s effect on student learning. Comparisons were made based on faculty gender, rank, age, and ethnicity. Findings suggest that despite statistical differences, when gender, rank, age, or ethnicity are considered, faculty are not in the habit of sending course materials like syllabi, project instructions, and lecture notes to students personally via email. Moreover, faculty tend to find favor with email communication and its effectiveness as a tool of teaching. The results of this survey coupled with previous research by the authors and other scholars suggest faculty ought to embrace the technology and develop positive ways to incorporate email, as well as other technology, into the educational process. 相似文献

For increased and various communication requirements of modem applications on embedded systems, general purpose protocol stacks and protocol models are not efficient because they are fixed to execute in the static mode. We present the Component-Based Communication Protocol Architecture （CCPA） to make communication dynamic and configurable. It can develop, test and store the customized components for flexible reuse. The protocols are implemented by component assembly and support by configurable environments. This leads to smaller memory, more flexibility, more reconfiguration ability, better concurrency, and multiple data channel support. 相似文献

The research examined the nature and scope of e-portfolio reflective writing by primary pre-service teachers about their classroom implementation of information and communication technologies. Familiar and new technologies require a teacher to be able to confidently identify the pedagogical potential for effective learning and teaching. With the author as a teacher educator, uncovering of aspects of commonality and patterns of emphasis in pre-service teachers’ reflective writing prompted reconsideration of established education practice. A qualitative thematic coding approach was adopted using an initial stimulus of Mezirow et al.’s notions of transformational learning: content, process and premise reflection. Extracts were coded by case, structurally and thematically using qualitative analysis software. Distinct categories emerged from cycles of analysis and a comprehensive typological map was created that provided insights into pre-service teachers’ emergent pedagogic thinking in relation to their use of technology whilst on school placements. The research led to revised scaffolding prompts, particularly in relation to premise reflection, for pre-service teachers engaged in reflective writing as a tool to transform and enrich their pedagogical understanding of the interplay between technology, teaching and learning. 相似文献

Sports video appeals to large audiences due to its high commercial potentials. Automatically extracting useful semantic information and generating highlight summary from sports video to facilitate users‘ accessing requirements is an important problem, especially in the forthcoming broadband mobile communication and the need for users to access their multimedia information of interest from anywhere at anytime with their most convenient digital equipments. In this paper, a system to generate highlight summaries oriented for mobile applications is introduced, which includes highlight extraction and video adaptation. In this system, several highlight extraction techniques are provided for field sports video and racket sports video by using multi-modal information. To enhance users‘ viewing experience and save bandwidth, 3D animation from highlight segment is also generated. As an important procedure to make video analysis results universally applicable, video transcoding techniques are applied to adapt the video for mobile communication environment and user preference. Experimental results are encouraging and show the advantage and feasibility of the system for multimedia content personalization, enhancement and adaptation to meet different user preference and network/device requirements. 相似文献

From a sample of 190 males and females (120 “young,”; 70 “old"), this study sought to determine differences in perceived levels of communication competence and communication satisfaction as a function of the main and joint effects of cohort‐centrism and perceived decoding ability. Analyses provided only weak support for the joint effects. However, older persons considered their conversational partners, whether young or old, to be more competent than did younger persons. Also, on the whole, older persons were more satisfied conversing with young persons, while younger persons were less satisfied, regardless of the age of the conversational partner. Those who perceived themselves as high decoders rated their partners as more competent than did those who perceived themselves as low decoders, and high decoders were also more satisfied with the interaction than low decoders. Cohort‐centrism was supported only in the case of low‐decoding older persons. 相似文献

Social media (SM) support new approaches to learning that rely on voluntary, peer-to-peer communication using devices and software provided and managed by students rather than on institutional course management systems. We present one case of such an approach with first-year university students (n = 86) in Thailand using SM for asking and answering questions between peers in a face-to-face computer-programming course. Encouraging students to ask questions about course content can result in improved performance. In general, understanding how students participate and what drives them to participate can provide insights into how universities and instructors can be socially ready. Students used SM during 10 weeks of an 18-week course. Each of four sections selected one form of SM as follows: Facebook [n = 33], Instagram [n = 21], Twitter [n = 21], and Line [n = 11]. The mixed-methods case study involved quantitative measures of how students participated and quantitative and qualitative measures of students’ perceptions of what drives or discourages their participation. Results revealed patterns in participation as follows: participation and motivation; passive and active participation; participation and sample size; participation and type of SM and; participation and student demographics. Implications for practice relate to the value of instructors’ understanding of the social incentives for student participation such as social recognition, gratification of needs and convenience. Implications for research focus on the value of investigating new forms of participation available to read-only participants and ‘lurkers’ using features of SM such as ‘liking’ and sharing. 相似文献
