教师—新闻从业人员—学生三位一体教学模式探讨

在新闻专业传统的课堂教学中,存在教师实践能力不足的现象,影响了课堂教学效果。实行三位一体的教学模式是解决这一问题的根本措施。这一模式的意义体现在：一是创新理论与实践相结合的教学模式,提高课堂教学效果;二是创新实践教学模式,将实践贯穿于学生学习的始终;三是创新案例教学模式,将最鲜活的案例带到课堂教学中;四是创新课堂作业评价模式,提高学生学习的积极性;五是创新与业界的互动模式,拓展学校的媒介资源。在实施这一教学模式的过程中,要注意注重加强教学管理、灵活安排教务工作、注重对新闻从业人员遴选、转变唯学历主义观念、加大对新闻从业者及媒体兼职教师的激励。     

Targeted advertising as a signal

This study presents a signaling model of advertising for horizontally differentiated products. The central ingredients of the model are two important characteristics of advertising—targeting, and noisy information content. The theory yields interesting results about the informational role of targeted advertising, and its consequences. First, targeting can itself serve as a signal on product attributes. Second, the effectiveness of targeting depends not only on firms knowing consumer preferences, but on consumers knowing that firms know this. This creates a distinction between strategies of targeting and personalization. Third, the effectiveness of targeting in equilibrium may (far) exceed the information contained directly in the targeted message. Fourth, information content is not, however, superfluous. Specifically, when ads contain no information, a targeting equilibrium does not exist. Together, these results reveal how advertising conveys information both through the content of the message and the firm’s choice of advertising medium. Furthermore, the model is robust to the various critiques of prior work on ads-as-signals: namely, that ad content is irrelevant, ad exposure is unnecessary, and the choice of ads as signals is inherently arbitrary.

The effect of political visibility on audit effort and audit pricing

This study examines whether auditors adjust their effort and pricing decisions for political visibility. We argue, from the behavioural literature, that political visibility will create the need for more justification by auditors. Using data on actual audit fees, hours and billing rates for a sample of New Zealand public sector companies, we find that total audit fees are positively related to the number of press mentions (our proxy for political visibility). Consistent with our expectations we find that audit fees are monotonically related to audit fees. We also find that auditors increase the hours spent on the audit but not billing rates, which further suggests defensive bolstering by auditors.     

Does the severity of a client’s negative environmental,social and governance reputation affect audit effort and audit quality?

In recent years, investors have begun to value companies’ reputations through their environmental, social, and governance (ESG) practices. ESG risk can affect business processes and controls and can heighten financial risk and threaten a firm’s survival. This study examines whether and how the severity of media coverage of a firm’s negative ESG issues (tainted ESG reputation) is associated with audit effort and audit quality. I find that auditors manage the higher expected engagement risk conveyed by tainted ESG reputation by applying higher audit effort. Next, I observe that the increased effort is associated with auditors likely detecting and requiring adjustments for material misstatements and that tainted ESG reputation is associated with fewer misstatements (i.e., reduces poor audit quality). The association between tainted ESG reputation and audit quality is driven primarily by increased audit report lag, not by increased audit fees. Further, I find that tainted ESG reputation is positively associated with audit effort and reduces poor audit quality for up to three years. The results also show that the audit effort and audit quality effect vary across the three components of ESG.     

Exploring the design of conscious media

Our existing model of media, based upon a consumptive-materialist–atomistic orientation, falls short in seeking to promote mainstream awareness of systemic and integral thinking in society-at-large. This paper presents evolutionary guidance media, a new model for media arising from evolutionary perspectives including systems science, humanistic, transpersonal and integral studies designed to promote planetary consciousness and give rise to an ecological–spiritual–integral mindset. Two key elements of evolutionary guidance media are discussed: a databank containing purposeful data from nine or more dimensions of human activity, and transception, the infusion of cyberception with qualities arising from mutual causality. Specific types of transception are introduced including Gaiaception, Agoraception, and Dharmaception. Organizations and companies already in the process of creating green media, socially responsible media, and spiritual, or transformational media are vanguards of the development of conscious media.     

Supplier integration in new product development: Computer mediated communication,knowledge exchange and buyer performance

In new product development (NPD), the buyer–supplier relationship is changing. Suppliers are becoming an integral part of the design team. This study investigates the effectiveness of computer-mediated and face-to-face communication channels on knowledge exchange between buyer and supplier firms, and ultimately buyer NPD and market performance. Open innovation literature and media richness theory are used to develop hypotheses which are then empirically tested using data collected from 157 R&D project managers from U.S. manufacturing firms. To date, empirical studies on the link between supplier integration and buyer performance show conflicting results. Structural equation modeling found a significant positive link between knowledge exchange and NPD performance, measured both in terms of effectiveness and efficiency, and a significant positive link between effective and efficient NPD and market performance. A surprising finding is that contrary to media richness theory, email can perform like face-to-face communication transmitting rich information and having a positive relationship to knowledge exchange between buyer and supplier. It was also found that with face-to-face communication, knowledge exchange fully mediates the relationship with effective NPD while with email communication knowledge exchange fully mediates the relationship with efficient NPD. Video conferencing was found to have no significant effect on knowledge exchange and the effect of web-based tools was significant and negative. The implications of these findings in theory and practice are discussed.     

媒体治理、政治关联与研发投资

以深圳证券交易市场2009-2013年创业板上市公司为样本,检验了媒体治理、政治关联与研发投资之间的关系。实证分析结果显示,媒体治理作用越强,公司的研发投资就越多。这表明,媒体能够有效发挥监督治理作用,促进公司创新。进一步分析显示,政治关联对媒体治理与研发投资之间的关系具有明显的反向调节作用。这意味着,政治关联抑制了媒体的治理作用。
