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

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

SUMMARY The authors will discuss two innovative methods of increasing the teaching roles of librarians by designing and grading assignments that count towards students' final grades. One of the authors has expanded her teaching role on campus by being involved in the development of Virginia Tech's First-Year Seminar. She participates in the design of lesson plans and serves as a facilitator for one of the fourteen sections. This includes all of the professor roles: meeting with the class once a week, working with the Student Teaching Assistant, assigning and grading assignments, holding office hours, facilitating class discussions, and dealing with course management and grading issues. The other author is integrated within a junior-level course with at least four contacts with the students. Three training sessions include hands-on practice in the database and in-class and homework assignments. The six assignments are 15% of the final grade in the course. The author has total control of this segment of the course: design of the assignments, teaching of the courses, grading of the assignments, and dealing with grading issues. The authors find that these expanded roles lead to deeper relationships with the teaching faculty and the students, due to the increased involvement. 相似文献

Public service has been seen as a powerful element in the professional self-definition of journalists. In this article I examine the renegotiation of the ideal of public service by analysing Finnish press journalists’ ways of constructing and representing it in interview talk. The data analysed consists of 32 in-depth interviews with press journalists conducted in 2003–4. The interviewees’ talk is understood discursively. Among the interviewees the discourse of the societal newspaper was challenged by that of the market-oriented press. According to the data analysed, the two discourses are simultaneously present and intertwined in the practice of newsrooms. Accordingly, they both appear fundamental in defining the future of the ideal of public service. For these reasons, the discursive negotiation of “good” journalism in the Finnish press can be characterized as a hybrid. What seems to be important is that together the discourses of the market-oriented newspaper and that of the societal newspaper form a continuum of different ideals and tasks; the professional role constructed for a journalist comprises a rich, fluid spectrum of responsibilities—informing, entertaining and empowering. 相似文献

Throughout the 28th century, numerous philosophers of history and time have questioned the most ingrained of all our beliefs: does time progress in a linear way and is the future simply the next chapter in this narrative?2 This essay proposes to rethink the future of museums outside of this narrative structure, one for which the future is reduced to words such as projection, prediction and prophecy. It asks: in an age of globalisation, can the museum still think of the future as the outcome of a chronological narrative? This essay takes one recent attempt (by the philosopher Catherine Malabou) to destabilise—again—this belief, and proposes to reveal the impact that this attempt could have on the museum's understanding of time and its place within it. 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

Abstract Students and faculty have come to expect off-campus access to the full portfolio of electronic resources made available by their library. They demand, and should be provided, simple access to electronic information sources 24 hours a day, 7 days a week, regardless of their location. Proxy servers have been the solution of choice for remote authentication for some time now, but library users tend to have difficulty with manually configured proxies, and there are beginning to be robust alternatives that can provide secure off-campus access to library resources. Remote authentication should not be a matter of getting a proxy server running and then forgetting about it. New developments should be investigated to ensure the easiest, most reliable and most secure access possible-in the interests of libraries and their users. 相似文献

In recent years, there has been rapid growth in the volume of research output on the topic of e-government. To understand this research better, we used content analysis of eighty-four papers in e-government-specific research outlets (two journals and one conference series). Our analytical focus took in five main aspects: perspectives on the impacts of e-government, research philosophy, use of theory, methodology and method, and practical recommendations. Normative evaluation identified some positive features, such as recognition of contextual factors beyond technology, and a diversity of referent domains and ideas. Alongside this, though, research draws mainly from a weak or confused positivism and is dominated by over-optimistic, a-theoretical work that has done little to accumulate either knowledge or practical guidance for e-government. Worse, there is a lack of clarity and lack of rigor about research methods alongside poor treatment of generalization. We suggest ways of strengthening e-government research but also draw out some deeper issues, such as the role of research philosophy and theory, and the institutional factors – particularly pressures of competition and time – that may constrain development of e-government as a research field. 相似文献
