Replies to comments made by Bornstein (see record 2005-01622-005) and Goodheart (see record 2005-01622-006)on the current author's original article (see record 2005-01622-004). The discussants of the author's article have given him much food for thought. In responding, he proposes that the human mind has several different unconscious adaptive processing systems, each with its own domain of operations. He also acknowledges that the hallmark of the strong adaptive approach is the thesis that death and death anxiety are the fundamental issues in human emotional life and its psychotherapies. He is prompted as well to enter the debate regarding the presence of universal structures in the emotion-processing mind and does so by offering a variety of scientific data and clinical observations that speak clearly for their existence. Finally, he presents some comparative clinical material to highlight the dramatic differences in the mental realms and level of insights negotiated by strong adaptive psychotherapists as compared with those who work in any other manner.

Weld metal grain structure and mechanical properties of the Ir-0.3 pct W alloy (DOP-26) doped with 60 ppm Th and 50 ppm Al
have been investigated by use of a gas tungsten arc (GTA) welding process. The fusion zone grain structure is strongly influenced
by heat input and puddle shape and therefore by the bead width. With increasing bead width from 2.5 to 3.7 mm, the grains
in the fusion zone show a sharp change in growth direction near the centerline region and develop a fine columnar structure
with grains growing parallel to the welding direction. Mechanical properties of the welds and base metal were characterized
by tensile and impact tests from 650 to 1150 °C. The ductility and fracture behavior of DOP-26 welds are sensitive to weld
bead width, postweld heat treatment, and weld-test orientation. The ductility of the welded specimens increases with increasing
test temperature and decreasing weld bead width. The transverse weld specimen with a wide-bead width (3.7 mm) has the lowest
impact ductility, and the longitudinal weld with a narrow-bead width (2.5 mm) has the highest elongation at all the test temperatures.
The impact ductility of the transverse weld specimen with the narrow-bead width falls between the limits. All the results
are discussed in terms of the fusion zone grain structure and fracture path of the welds. 相似文献

Recently, Developmental Psychology published 2 articles on the shape bias; both rejected the authors' previous proposals about the role of attentional learning in the development of a shape bias in object name learning. A. Cimpian and E. Markman (2005; see record 2005-14938-017) did so by arguing that the shape bias does not exist but is an experimental artifact. A. E. Booth, S. R. Waxman, and Y. T. Huang (2005; see record 2005-05098-004), in contrast, concluded that the shape bias (and its contextual link to artifact categories) does exist but that the mechanisms that underlie it are conceptual knowledge and not attentional learning. In response, in this article the authors clarify the claims of the Attentional Learning Account (ALA) and interpretations of the data under question. The authors also seek to make explicit the deeper theoretical divide: cognition as sequestered from processes of perceiving and acting versus as embedded in, and inseparable from, those very processes.

The effect of heat treatment on the parameters of the porous structure of powders in the system Sn(IV) Sb O is studied. It is established that xerogels of coprecipitated tin and antimony hydroxides dried at 360 K are microporous adsorbents containing particles of both crystalline and amorphous phases. During powder heat treatment there is formation of solid solutions based on tin dioxide and there is redistribution of the microporous structure into a mesoporous structure. This is accompanied by a reduction in specific surface and an increase in pore size. 相似文献
