An increasing number of aging community providers and consumers support consumer-direction (CD) in long-term care services. In regard to devolution, consumer-direction goes beyond the usual approach of shifting responsibilities from the federal government to state governments to bring programs "closer to the people." Consumer-direction goes even further by placing resources directly in the hands of consumers. Yet, many questions remain unanswered regarding how to implement CD personal assistance services in general, and especially for older persons. This article describes the importance of examining views from multiple key stakeholders involved in implementing CD programs. We report on three background studies that have informed the Cash and Counseling Demonstration and Evaluation (CCDE) design and implementation-policy expert interviews as well as surveys and focus groups with consumers and representatives. As a fourth data source, we drew upon experiences in designing the CCDE and initial results from the first year of implementation. Each of the three studies on its own provided essential information for planning the CCDE. However, when we examined the studies together, and added CCDE design and implementation experiences, views expressed by the different stakeholders formed a type of multi-perspective "dialogue" that expanded our knowledge about implementing CD services. We hope this increased knowledge will help expand the availability of such services for consumers of any age who want to direct their own care.  相似文献

The research presented employed critical discourse analysis to examine advice columns on sex and women's sexual freedom as expressed in two popular women's magazines, Essence and Cosmopolitan, over a three-year period. Essence has a Black female audience, Cosmo a predominantly White female audience. Critical discourse analysis is concerned with language as a primary force for the production and reproduction of ideology and belief systems that come to be accepted as common sense. The study asked whether and to what extent sex talk in these two magazines mirrored tenets of sexual liberation as set forth by “second-wave feminism.” Findings showed that while both magazines reinforced women's right to sexual pleasure and to ask for what they wanted, Essence came closest to mirroring the tenets of women's liberation by advocating women's right to say no to men's bad behavior and to be their own persons. By contrast, Cosmo advised women to be innovative in exciting and keeping their men and to be more flexible in managing men's less than desirable behavior.  相似文献

The relationship between individuals?? entrepreneurial behavior and objective situational characteristics of an entrepreneurial opportunity??individual-opportunity nexus??lies in the focus of entrepreneurship research. The role of subjective appraisals and affective influences in the pre-entrepreneurial process was neglected in this context so far. On the basis of a questionnaire experiment with two different samples of employees and entrepreneurs, our results confirm central assumptions of cognitive appraisal and emotion theories. The subjective appraisals of objective entrepreneurial opportunities better predict entrepreneurial evaluation and exploitation decisions than the objective characteristics of the entrepreneurial opportunity. Furthermore, the results show in addition to an inverse direct effect of negative affect that the relationship between the entrepreneurial evaluation and exploitation is negatively moderated by negative affect. Our analyses indicate that the two subsamples show differences in their cognitive processes, but that they are still generally comparable. The affective influences on the pre-entrepreneurial process, however, demonstrate no group specific differences. These results extend the individual-opportunity-nexus-paradigm that is based on objective characteristics by examining the meaning of subjective appraisals and affective reactions and therefore the intersection of individuals and entrepreneurial opportunities.  相似文献

Since Ulrich (Human resource champions: the next agenda for adding value and delivering results, Boston, Harvard Business School Press, 1997) shaped the strategic role of HR managers, his concept of an HR business partner has been controversially discussed by researchers and practitioners. Explanations about when and how HR managers act as strategic business partners have found limited attention in the literature. Based on the theory of reasoned action developed by Ajzen und Fishbein (Understanding attitudes and predicting social behavior, Englewood Cliffs, Prentice-Hall, 1980; J Pers Soc Psychol 27(1):41?C57, 1973), we hypothesize a positive relation between personal attitudes as well as subjective norm and the behaviour of HR managers to act as a strategic business partner. Results of the German Cranet survey in 2009 show that expected positive consequences influence the personal attitude, whereas the acceptance of the human resources as well as the existence of an HR strategy within the organisation is positively related with subjective norm. Hence, both attitude and subjective norm positively influence the behaviour of HR managers to act as a strategic business partner.  相似文献

Coopetition has become a heated issue in the last decade. In this study, a scrutinized review of previous research on coopetition is presented to clarify the research stream on coopetition, from which the implications are derived and a framework to analyse the phenomenon is proposed. Given the complex nature of coopetition, an in‐depth case study was undertaken to investigate the competition–cooperation relationship and coopetition performance over a 15‐year period in a Taiwanese supermarket network, which was formed by a focal company and its competitors. Performance was analysed before and after launching the coopetition strategy, in which 31 indicators were examined. The findings imply that competition (Yang) and cooperation (Yin) are reciprocally rooted in and mutually promoted by each other. The findings also confirmed that cooperation with competitors did lead to better performance, at least over a period, in two ways. The first was that the adoption of coopetition permitted the attainment of performance levels beyond what would otherwise have been possible; the second was that the adoption of coopetition changed the timeframe, permitting earlier achievement of higher performance levels. This study contributes to and extends knowledge of the dynamics and consequences of cooperation with competitors and demonstrates that coopetition has a significant temporary advantage.  相似文献

We propose a shift in emphasis when communicating to people when the objective is to motivate household disaster preparedness actions. This shift is to emphasize the communication of preparedness actions (what to do about risk) rather than risk itself. We have called this perspective “communicating actionable risk,” and it is grounded in diffusion of innovations and communication theories. A representative sample of households in the nation was analyzed using a path analytic framework. Preparedness information variables (including content, density, and observation), preparedness mediating variables (knowledge, perceived effectiveness, and milling), and preparedness actions taken were modeled. Clear results emerged that provide a strong basis for communicating actionable risk, and for the conclusion both that information observed (seeing preparedness actions that other have taken) and information received (receiving recommendations about what preparedness actions to take) play key, although different, roles in motivating preparedness actions among the people in our nation.  相似文献

The role of information processing in understanding people's responses to risk information has recently received substantial attention. One limitation of this research concerns the unavailability of a validated questionnaire of information processing. This article presents two studies in which we describe the development and validation of the Information‐Processing Questionnaire to meet that need. Study 1 describes the development and initial validation of the questionnaire. Participants were randomized to either a systematic processing or a heuristic processing condition after which they completed a manipulation check and the initial 15‐item questionnaire and again two weeks later. The questionnaire was subjected to factor reliability and validity analyses on both measurement times for purposes of cross‐validation of the results. A two‐factor solution was observed representing a systematic processing and a heuristic processing subscale. The resulting scale showed good reliability and validity, with the systematic condition scoring significantly higher on the systematic subscale and the heuristic processing condition significantly higher on the heuristic subscale. Study 2 sought to further validate the questionnaire in a field study. Results of the second study corresponded with those of Study 1 and provided further evidence of the validity of the Information‐Processing Questionnaire. The availability of this information‐processing scale will be a valuable asset for future research and may provide researchers with new research opportunities.  相似文献
