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.

Studies on the interactions of metal oxides and Na2 SO4 at 1100 and 1200 K in oxygen

The interaction of different metal oxides such as Co₃O₄, NiO, Al₂O₃, Cr₂O₃, Fe₂O₃ and SiO₂ with Na₂SO₄ at a temperature of 1100 and 1200 K in flowing oxygen has been studied. The thermogravimetric studies for each system were carried out as a function of Na₂SO₄ in the mixture. The presence of different constituents in the reaction products were identified by X-ray diffraction analysis and the morphologies of the reaction products were characterized using metallography and scanning electron microscopy (SEM). The formation of products was also investigated by thermodynamic computation of free energies of the reactions and the study of relevant equilibrium phase diagrams. The soluble species in the aqueous solutions of the reaction products were determined quantitatively using atomic absorption spectrophotometry. The high temperature interaction products usually contain a 3-phase structure namely, Na₂O·M₂O _x , M₂O _x and metal sulphide and/or metal sulphate. The formation of Na₂O·M₂O _x depends upon the solid state solubility of metal oxide in the molten salt at high temperatures. Under limited solubility conditions Na₂O·M₂O _x is invariably formed, but as soon as this condition is relaxed the oxide. M₂O _x , precipitates and forms a separate phase.     

美国西雅图先锋广场历史保护区的形成

考察美国西雅图先锋广场历史保护区形成的过程,可以看出城市历史文化遗存的保护是经济与历史文化合力作用的结果,公众参与在城市历史文化保护工作中发挥着重要的作用。我国城市经济高速发展,保护与发展的矛盾冲突还没得到很好解决,先锋广场的例子对我们具有一定的参考价值。     

在传统中探寻当代海报的本土设计

在设计国际化的影响下,中国现代视觉设计中充满了受西方影响的视觉语言,“国际化”视觉符号的泛滥与“本土化”视觉语言的失语视觉现象非常突出。作为当今社会人与人交流载体的海报设计,要走出一条“民族个性”的道路,就必须根植于民族文化土壤中,向传统学习,并进行具有创造性的转化,使传统文化符号在当代海报设计中既具有“民族个性”又有“时代性”,这样,我们海报设计才能真正走“国际化”。

Remarks on different reviews of Chinese character recognition

This paper gives an introduction and remarks on two review papers for Chinese character recognition. One review is made by Chinese authors, another is from American scientists. They investigate Chinese character from different language environments; they do the research from different points of view. Thus, a more comprehensive view on Chinese character recognition, which is an important branch of pattern recognition, can be provided to the readers. Meantime, one article pays attention to online process, and other paper deals with offline recognition, which complement each other. The author is the Associate Editor-in-Chief of Frontiers of Computer Science in China
