Abstract This paper discusses the application of the means‐end chain (MEC) framework for investigating customers cognitive”; structure regarding community applications. It is argued that the understanding of customers cognition is crucial for the development of sustainable communities. MEC analysis is seen as a mean to support the community design tasks, especially concept development. The MEC analysis within concept development helps to improve the success rate of a newly designed community by the early integration of customer needs and benefits. Based on theoretical considerations about the MEC framework and its limitations a case study regarding an information community is illustrated. Data was collected conducting individual laddering interviews online at a major information portal in Germany. Dividing answers into attributes, consequences, and values and using content analysis hierarchical value maps (HVM) for both, messaging applications and information ‐portals, were constructed. To support concept development of a new information community, as a distribution platform for content, the findings of both HVMs were considered. Examples illustrate, that the MEC analysis helps to create a community concept that is focused on the targeted customers. It is supporting the creative process of finding community functions and features that are fitting or can be linked to the existing cognitive structures. 相似文献

Bundling can be a pricing mechanism by which monopolists capture economic surplus from consumers.We suggest that given the cost structure of media markets, channel bundling in the cable and satellite market could also emerge in a competitive environment. A la carte channel pricing on cable television may or may not increase consumer welfare and could decrease total welfare. Because bundling may create other problems, policymakers may consider allowing cable and satellite networks to sell packages of channel space to viewers at a given price, allowing viewers to choose which channels they want in their packages. We term this option quasi-bundling. 相似文献

This paper reviews events of SSP 2013 and AAUP 2013 within the context of Nassim Nicholas Taleb's notions of Black Swans (unexpected game changers) to anticipate the formation of competitive arenas (i.e. new models and revenue streams) for scholarly communications. It examines Tim O'Reilly's keynote address at SSP 2013, the advice of Michael Schrage from the opening Plenary at AAUP 2013, and Tim Sullivan's discussion of Harvard Business Publication's use of a topical blog network as new publishing platform to access global digital communications networks. The essay extrapolates from the case studies presented to overlay the strategies of successful practitioner presses and the advice of sought‐after business consultants on the work of academic houses, to imagine the next competitive frontier(s) in scholarly publishing. 相似文献

In the early 19th century, public libraries in America tended toward grand appearances befitting seriousness of purpose. Library design changed gradually throughout the 20th and 21st centuries, and more dramatically with automation and new technology. True to its roots, the public library continues to maintain areas for quiet, individual study. But, in addition, today’s library has become a cultural center in the community, offering art galleries, auditoriums, meeting rooms, spaces for collaborative work, digital information and instruction, and even cafés. Change is inevitable, as innovations in library design and patron use illustrate. Yet, from the earliest libraries to modern times, one overarching constant defines their purpose: libraries inspire. 相似文献
