The concept of competitive displacement is central to theories of media evolution, and the threat that the Internet has posed to printed newspapers provides an ongoing case study on the topic. In particular, this situation offers an opportunity to examine the strategic efforts of print newspapers to prevent competitive displacement, as well as the effectiveness of these strategies. This article addresses these issues through an analysis of a unique data set, constructed from 20 years of newspaper circulation data, as well as data on local market characteristics, newspaper staffing and content variety, and state-level Internet penetration. Specifically, this article examines whether, and to what extent, these competitive strategies impacted local print newspaper circulation trends over this 20-year time period. This analysis focuses on the following strategic responses: (a) newspapers’ launching of online versions (a diversification strategy within the language of media evolution literature); and (b) newspapers’ efforts to cover a greater variety of subject areas, as measured by the number of editors and special editorial sections produced. (The authors characterize these as a “mimicking” strategy from media evolution literature, as this strategy essentially represents an effort to simulate the much greater content variety that readers can find online). This article examines the relationships between these circulation, strategic, and Internet penetration variables over a 20-year time period, while also taking into account relevant characteristics of local newspaper markets.  相似文献

This study examined underground iron ore miners' occupational narratives to uncover how their stories socialize miners into blue-collar careers and reinforce their work identities. Through the root theme of sisu (Finnish for inner determination), underground miners create a status hierarchy that is used to construct a sense of pride around their work and to establish milestones of success for themselves and others in their workgroup. Furthermore, they communicatively construct exemplars that guide their performance and decisions during the unfolding of their work experiences. Their discourses provide alternatives to white-collar conceptualizations and practices of careers and success.  相似文献

This paper reports on a study in the area of informal science education in the contexts of science museums. The research focused upon two areas: first, perceived novelty and its effect on cognitive learning in year eight students visiting an interactive science museum; second, the links between exhibits which were most frequently recalled and exhibits which students later recalled as being interesting and puzzling. Results on a post-test of cognitive learning of concepts and principles associated with the exhibits suggested that students who underwent novelty reducing pre-orientation to the physical environment and had prior visitation experience learned more than their counterparts. Gender did not influence learning when perceived novelty level and prior exposure were considered. Furthermore, the most frequently recalled exhibits shared a combination of characteristics such as large physical size, prominence in the exhibit galleries, and the diversity of sensory modes that they employed. Finally, it appears that cognitive learning is likely to occur for exhibits which are most memorable.  相似文献

It is a truism that the design and deployment of information and communication technologies is vital to everyday life, the conduct of work and to social order. But how are individual, organisational and societal choices made? What might it mean to invoke a politics and an ethics of information technology design and use? This editorial paper situates these questions within the trajectory of preoccupations and approaches to the design and deployment of information technology since computerisation began in the 1940s. Focusing upon the dominant concerns over the last three decades, the paper delineates an interest in design and use in relation to socio-technical theories, situated practices and actor-network theory. It is argued that each of these approaches is concerned with a particular form of politics that does not explicitly engage with ethics. In order to introduce ethics into contemporary debates about information technology, and to frame the papers in the special issue, it is argued that Levinas’ ethics is particularly valuable in problematising the relationship between politics and ethics. Levinas provides a critique of modernity’s emphasis on politics and the egocentric self. It is from a Levinasian concern with the Other and the primacy of the ethical that a general rethinking of the relationship between politics, ethics and justice in relation to information and communication technologies can be invoked.  相似文献

International research collaboration raises questions about how groups from different national and institutional contexts can work together for common ends. This paper uses issues that have arisen in carrying out the first stage of an international research project to discuss a framework designed to map different kinds of multi-national research collaboration in terms of increasing complexity and increasing time to research outputs. The paper explores factors that enable and that constrain progress in carrying out collaborative research. The paper highlights the complex interplay within research practice of factors that derive from institutional structures and those that appertain to individuals as agents. It uses the personal and collective reflexive deliberations of the authors, to demonstrate that as the complexity of the research interface increases, and as the time to research outputs increases, so structural risk increasingly develops into agentic risk, and that structural risk becomes increasingly required to be managed through agentic action.  相似文献

The proposed advising model focuses on creative learning. To operationalize such a model, there must be not only structural but behavioral changes in the existing system. This requires that professional educators have special concern for the quality of relationships between faculty and students. In a program which focuses on creative learning, most students need assistance in developing the understanding and skill necessary for creative learning. An alternative advising model is proposed, therefore, which enhances the behavioral requirements. The alternative model views the advising function as a teaching-consulting function with a priority goal of helping the student learn the art of self-evaluation as a prerequisite to life-long learning.  相似文献
