蒸汽减压站自控系统的巧设计

蒸汽是石油化工装置中最重要的物料。随着石油化工工业的迅猛发展 ,蒸汽在其中扮演着越来越重要的多重角色。因此 ,对蒸汽系统的平稳控制 ,对石油化工生产装置平稳、高效地运行是至关重要的。传统的蒸汽减压站自控系统基建投资大 ,紧急情况下靠人工手动操作稳定蒸汽压力系统 ,往往造成生产的波动或大面积的停车。针对传统蒸汽减压站自控系统的弱点 ,提出蒸汽减压站自控系统的优化设计方案 ,该方案得以在大型生产装置成功应用。新方案不但节省了大量的基建投资 ,而且取得了良好的生产效益

校园文化与大学发展

校园文化看不见、摸不着，却支撑着大学的脊梁，它潜移默化影响和造就一所大学的文化品格。它不仅对大学发展起着重要作用，也是大学发展的重要内容，是大学建设的题中应有之义。为此，需要建设民主和谐，具有学术自由、人文精神和创新精神的校园文化，并将它提高到学校战略发展的高度来看，以校园文化整合学校发展战略。     

The five elements and chinese-american mortality.

D. P. Phillips, T. E. Ruth, and L. M. Wagner (1993) reported that 1969-1990 California mortality data show that Chinese Americans are particularly vulnerable to diseases that Chinese astrology and traditional Chinese medicine associate with their birth years. For example, because fire is associated with the heart, a Chinese person born in a fire year (such as 1937) is more likely to die of heart disease than is a Chinese person born in a nonfire year. However, many diseases were excluded from this study, some diseases that were included have ambiguous links to birth years, and the statistical tests were indirect. A more complete statistical analysis and independent California mortality data for the years 1960-1968 and 1991-2002 did not replicate the original results.

Is evidence-based practice diverse enough? Philosophy of science considerations.

In its policy rationale for evidence-based practice in psychology (EBPP), the APA Presidential Task Force on Evidence-Based Practice (see record 2006-05893-001) claims to have constituted itself with "scientists and practitioners from a wide range of perspectives and traditions, reflecting the diverse perspectives within the field" (p. 273). We applaud this attention to diversity but contend that an entire perspective of the debate was omitted in the Task Force's newly approved policy and its underlying report. The failure to consider a philosophy of science perspective led the Task Force to make a number of epistemological assumptions that are not based on evidence or rationale and that thus violate the very spirit of evidence-based decision making. In this comment, we reveal a few of these assumptions and discuss their detrimental consequences. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Exploring the landscape of modern academic psychology: Finding and filling the holes.

Like any other domain of human activity, psychology has its fads and fashions. One consequence of fads is an overconcentration of resources on specific problems or approaches, which leaves other important problems or approaches (holes) underappreciated and understudied. This article is primarily about different factors (such as negativity bias, polarization of positions, focus on internal causes of behavior, dedication to a narrow view of what science is) that result in holes and about explorations of some of these holes that have interested the author. Psychologists should look more in the holes left behind by current enthusiasms. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Review of The saturated self: Dilemmas of identity in contemporary life.

Reviews the book, The saturated self: Dilemmas of identity in contemporary life by Kenneth J. Gergen (see record 1991-97621-000). There is, perhaps, no other concept as seminal for psychology as the self. For this reason alone, Kenneth Gergen's book represents an important contribution to our understanding of this influential concept. However, Gergen's vision is so broad, his arguments so compelling, and the implications so revolutionary, that the work defies confinement exclusively within the walls of academia. In essence, Gergen is articulating his vision of a postmodern world, and he lays an invitation squarely before the reader to come and partake. The conception of the self as private and autonomous is the focus of Gergen's postmodern challenge. In his chapter, "Social Saturation and the Populated Self," Gergen postulates that technological innovation in contemporary society has made possible a rapid proliferation of relationships. This he refers to as the "process of social saturation." Gergen's book constitutes a substantive contribution to psychology's on going understanding of the self. Copious examples are provided throughout, drawing on and extending scholarly debates. Also included are anecdotes and evidences from such far ranging domains as art, film, music, literature, and architecture. These not only clarify and reinforce his arguments, but also illustrate the scope and practicality of the position he espouses. Although readers may not embrace the gestalt of Gergen's vision of a postmodern culture, they are certain to find this book to be a provocative and rewarding read.
