This article explores the vulnerability of publicly held broadcasting companies to hostile takeovers. It finds that such companies are more attractive to investors than typical corporations, but that broadcasters are better defended against unfriendly takeovers and not especially vulnerable to takeovers. 相似文献

A field test was used to assess the efficacy of pay per view (PPV) and how PPV compared to pay cable programming and vidéocassette recorder (VCR) rentals. Owners of VCRs perceived PPV differently than did nonowners of VCRs. Differences were observed along the dimensions of convenience, ease of operation, control, and perceived value. PPV perceptions did not vary by those currently subscribing to pay cable. 相似文献

This study assessed the relationships between parent communication variables and the parent bonding factors of care and overprotection using a sample of 38 deaf and hard-of-hearing individuals connected with mental health services who had DSM-III-R or DSM-IV diagnoses of depression-related disorders. The 22 therapists working with these individuals also contributed to data collection. Results based on revised depression (BDI-R) and parent bonding (PBI-R) questionnaires, together with background data from both clients and therapists, indicate that higher ratings of depression are associated with less perceived care by mother and greater perceived overprotection by both mother and father. Paternal care and overprotection were negatively correlated, as were maternal care and overprotection. In comparison to hard-of-hearing counterparts, deaf participants were less depressed and had more positive ratings of communication with their parents. The BDI-R scores positively and significantly correlated with coded severity of diagnosis. Due to the small sample size, findings are suggestive. Further study is warranted. 相似文献

Since the early 1980s there has been increasing debate about research ethics and a gradual increase in the institutionalisation of ethics approval and monitoring. Initially this occurred in areas of biomedical research, but more recently all areas of research which involve human beings as sources of data have been included. Australia, along with other nations, has been intimately involved in these developments and now has a firmly established structure of Institutional Ethics Committees (IECS) topped by the Australian Health Ethics Committee (AHEC) for the approval and monitoring of human research ethics. Although there are guidelines and codes of practice, many issues remain still to be resolved as the panoply of research methods and practices is extended and encountered. Australian research in open and distance education is being caught in the embrace of IECs and their guidelines, and the Open and Distance Learning Association of Australia is preparing its own code of research ethics. This article outlines the context and discusses the major ethical issues and implications for research in open and distance education. It considers issues of both principle and practice, and points to some of the special circumstances which researchers in open and distance education face. 相似文献

With the increasing challenges facing professional engineers working in more complex, global and interdisciplinary contexts, different approaches to understanding how engineers practice and learn are necessary. This paper draws on recent research in the social sciences from the field of workplace learning, to suggest that a practice-theory perspective on engineers' professional learning is fruitful. It shifts the focus from the attributes of the individual learner (knowledge, skills and attitudes) to the attributes of the practice (interactions, materiality, opportunities and challenges). Learning is thus more than the technical acquisition and transfer of knowledge, but a complex bundle of activities, that is, social, material, embodied and emerging. The paper is illustrated with examples from a research study of the learning of experienced engineers in the construction industry to demonstrate common practices – site walks and design review meetings – in which learning takes place. 相似文献

Two hundred fifty‐nine preservice teachers at a medium‐sized university in the Southwest participated in the current study. The participants were randomly assigned to a labeled condition, Attention Deficit Hyperactivity Disorder, or nonlabeled condition, and were presented a vignette in one of three forms: a written case study, a video clip, or a written case study with a video clip. The vignette described an elementary school aged child displaying disruptive behavior, while the video portrayed a similar aged child exhibiting disruptive behavior in the classroom. Following the presentation of the vignette, participants made judgments about the child's social skills and attentional skills by completing an examiner‐made rating scale. There was a significant main effect for the label condition on judgments of attention; participants in the labeled condition made significantly more negative judgment than did those in the nonlabeled condition. There were also significant main effects for the participants' high school location and vignette treatment. © 2004 Wiley Periodicals, Inc. Psychol Schs 41: 221–234, 2004. 相似文献
