Several theoretical approaches have been put forth to predict and explain the effects of teleconferencing technologies. One approach is to examine the functions of nonverbal signals and to make predictions based on the fact that different teleconferencing technologies allow nonverbal communication to different extents. One of the functions of nonverbal signals is to allow the listener to provide feedback to the speaker in a communication. Prior research has shown that such feedback enhances listener comprehension. In this study, it was hypothesized that different teleconferencing technologies would allow different levels of feedback based on their ability to accommodate nonverbal signals, and this in turn would affect comprehension. An experimental study was conducted to compare comprehension, feedback, and satisfaction in telephone and computer conferencing. The study confirmed that comprehension and speaker satisfaction are related to feedback, but failed to show a relationship between listener satisfaction and feedback. No difference in comprehension, listener, or speaker satisfaction was observed across teleconferencing technologies. Role-related differences were observed between the speaker and the listener. It is suggested that the effects of teleconferencing technologies can be mapped systematically by examining each of the functions of nonverbal signals, one at a time. 相似文献

In this note, we make some remarks on the construction of sequences of independent identically distributed random variables and of Markov chains concretely on a probability space (Ω,A,P). We also show that there are non non-trivial martingales of exponential type. 相似文献

This study investigates the relative influences of professional values and selected demographic variables on the ethical perceptions of services marketing professionals. The relationship between ethical perceptions and ethical judgments of service marketers is also examined. The data were obtained from a mail survey of the American Marketing Association's professional members of service industries. The survey results indicate a positive relationship between a service professional's professional values and his/her perceptions of ethical problems. The results also suggest that ethical judgments of a service professional can be partially explained by his/her perceptions of ethical problems. Implications of the research findings were discussed.

In this paper, we consider the case of finite time dimension in the panel stationarity tests with structural breaks. By fixing T, the finite sample properties of the tests for both micro (T small and N large) and macro (both T and N large) panel data are generally greatly improved. More importantly, the derivation of the tests for finite T and , as opposed to joint asymptotic where N and simultaneously, avoids the imposition of the rate condition making the test valid for any (T, N) blend. Four models corresponding to the usual combination of breaks are considered. The asymptotic distributions of the test are derived under the null hypothesis and are shown to be normally distributed. Their moments for T fixed are derived analytically employing Ghazal’s corollary 1. The case with unknown breaks is also considered. The proposed tests have generally empirical sizes that are very close to the nominal size. The Monte Carlo simulations show that the power of the test statistics increases substantially with N and T. 相似文献

Increased tradability of services, made possible by the information and communications technology (ICT) revolution, has been at the heart of the internationalization of services. Although rapid growth of the services trade between parents of multinational enterprises (MNEs) and their overseas subsidiaries has contributed to the internationalization of services, empirical studies examining the determinants of intra‐MNE trade in services are few. This article, using the ownership, location, and internalization (OLI) framework, attempts to explain intra‐MNE trade in services. The results provide strong support for the OLI perspective, and posit a complementary relationship between manufacturing foreign direct investment and intra‐MNE services trade. The results also suggest the importance of subsidiaries' absorptive capacity and breadth of global connectedness for intra‐MNE trade. 相似文献

Family influences on economic performance are investigated. In particular, sibship sex composition is related to hourly wages using data from the National Longitudinal Survey of Youth 1979. The wages of men are increasing in the proportion of siblings who are brothers, but the wages of women are insensitive to sibling gender. Nonwage outcomes are generally unaffected. Contrasts by age structure and demographic group are also presented. The analysis addresses econometric challenges like the endogeneity of fertility and selection into the workforce. In addition, mechanisms such as labour market interactions, human capital investment and role model effects are documented. A questionnaire on job search indicates a same-gender bias in the use of brothers and sisters in obtaining employment. Developmental and psychological assessments suggest that brothers may be associated with worse childhood home environments and more traditional family attitudes among women. The findings are policy relevant and contribute to an understanding of gender differences and earnings inequality. 相似文献
