The classical concept of entropy is shown not to reflect the essence of the second law of thermodynamics both phenomenologically and theoretically. A new concept of entropy, S n , is given, which offers a particular physical meaning of entropy and provides an experimental determination of the entropy value. This allows one to avoid many attempts at defining the phenomenon of life via entropy characteristics and give definitions of life and an elementary structure of both life itself and devices that simulate life (automata, computers, and robots.). This, in turn, allows one to assign a substantive sense to the mathematical character of corresponding sciences (information theory, cybernetics, system theory, etc.) and define operational basic concepts of information, knowledge, meaning, and control, as well as to formulate operational concepts of order, organization, and self-organization and implement a new approach to problems of biology, biophysics, information theory, cybernetics, and system theory.  相似文献

本文从责权利角度论述了媒体责任、权利与规范之间的一般关系。认为职业规范是由职业责任与权利共同决定的,职业责任与职业权利是促使媒体伦理规范形成和发展一个必然的、永恒的基础和动力。本文认为“完成责任必须用好权利,正确地使用权利是第一位的责任”。具体来说,职业权利=职业权力+职业利益。因此,针对媒体权力部分的规范是为了防止媒体职业权力的异化,对媒体利益的规范是用以保证媒体及记者收益和正当性。  相似文献

During the last decade, behavioral economics has become an important and pervasive field. Since it draws from both psychology and economics, we tested four databases to compare coverage: EconLit, PsycINFO, Business Source Premier, and Academic Search Premier. We also explored which journals contain most articles on the subject, tracked the dates of those articles, and looked at trends in authorship. Finally, we show how the boom in behavioral economics research is reflected in the increase of working papers on the subject.  相似文献

This paper investigates chemical bleaching of wood to make species-specific practical recommendations for colour adjustment of veneer in furniture conservation. In more detail, chemical bleaching of Honduras mahogany (Swietenia macrophylla), European walnut (Juglans regia), Rio rosewood (Dalbergia nigra), padauk (Pterocarpus spp.), and purpleheart (Peltogyne spp.) is investigated using 11 different bleach solutions. Both oxidative (e.g. hydrogen peroxide and potassium permanganate) and reductive (e.g. oxalic acid and sodium bisulphite) solutions were used. The results show that the wood species react differently with the investigated bleach solutions. It can also be noted that not all investigated solutions were suitable for all wood species. Based on the results, wood species-specific bleach solutions are recommended.  相似文献

This study examines the relationships among workload, news autonomy, burnout, job satisfaction, and turnover intention among Taiwanese reporters. Results of a survey of 1,099 reporters indicate that workload and news autonomy were significantly associated with burnout. In addition, burnout was found to be negatively related to job satisfaction, which in turn had a significant effect on turnover intention. The results not only highlight the important role of workload and news autonomy in predicting burnout, but also extend previous research on journalist burnout by showing that job satisfaction acts as a mediator in the relationship between burnout and turnover intention.  相似文献

Have librarians promoted end user searching to the detriment of the profession and promoted clinical inefficiency from causally trained health practitioners? Issues related to the complexity of bibliographic retrieval in the networked environment are explored within the context of evidence-based medicine and the division of labor.  相似文献

Lesbian, gay, bisexual, and transgender (LGBT) persons, while widely diverse in many ways, share health disparities related to the stigma and discrimination they experience, including disproportionate rates of psychiatric disorders, substance abuse, and suicide. Lesbians, gay men, bisexuals, and the transgender communities have additional health concerns and disparities unique to each population. This paper highlights the national recognition of these health issues and disparities and presents web-based information resources about them and their mitigation.  相似文献

This investigation explored the relationship between value-relevant (VRI), impression-relevant (IRI), and outcome-relevant involvement (ORI) on information-seeking behaviors, attitudes, and purchase intentions. Results revealed that grocery shoppers' (N = 175) ORI was positively associated with information-seeking behaviors, attitudes, and purchase intentions of foods high in fiber. Neither VRI nor IRI predicted attitudes or purchase intentions. Results are discussed with an emphasis on information seeking among the three types of involvement and message-design strategies with respect to promoting foods high in fiber.  相似文献
