High-Activity Heterogeneous Catalysts Prepared in One Step from the Mesophases of Metallosurfactants

Surfactant Ru(II) complexes have been used to template mesoporous silicates using the true liquid crystal templating method, giving evenly dispersed, nanometer-sized ruthenium particles which show very high catalytic activity and selectivity in the hydrogenation of 1-hexene.     

Strange bedfellows.

The appearance of a book of readings on the exceptional child has brought to attention the fact that at least 10 texts on the subject, published in the past 10 years, continue the convention of including the gifted child in this classification. This seems to me to be an unfortunate association, if only from the standpoint of semantics. Granted that the gifted child needs special provision for his education, he still differs from the rest of the exceptional children in that he cannot be described as "handicapped." His need for education will not be met in the special class which is suitable for the various handicapped children. Moreover, this emphasis on the inclusion of the gifted child among the quite divergent groups of exceptional children seems to put undue stress on the problem nature of education for this group. Under present conditions of mass education it has been necessary to compromise our goals, but we still hope to make it possible for each child to develop to the best of his ability.

Passages of psychologists: Career stages of internship directors.

90 predoctoral internship training directors (mean age 43.3 yrs) completed a survey assessing their career stages. Five stages are identified, including entry, identity, doubt, reimmersion, and exit, and the content and time frames associated with each stage are discussed.

Editorial/éditorial.

Feedback from colleagues suggests that many psychologists are not aware of the range of articles considered appropriate for publication in the Canadian Psychological Review/Psychologie Canadienne. In an attempt to clarify the purview of the journal, a number of sections have been developed which are designed to reflect the general statement of editorial policy which is carried regularly on the inside front cover. The sections are entitled Reviews, Professional Issues, De Rerum Novarum, and Correspondence. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Generalization of verbally conditioned self-acceptance to social interaction in small group discussions.

Discusses generalization of change in a socially relevant variable during verbal conditioning trials to social behavior in small groups. On the basis of scores obtained on the E. M. Berger (see 27:7) scale of expressed acceptance-of-self and expressed acceptance-of-others, 2 groups of student nurses were selected for study: (a) a low self-acceptance group (low s-a) (N = 44), and (b) a high self-acceptance group (high s-a) (N =20). The low s-a Ss were randomly assigned to experimental (i.e., reinforced) and control (i.e., nonreinforced) conditions. All low s-a Ss participated in pre- and postconditioning, 4-person discussion groups. Similar preconditioning discussion groups were held for high s-a Ss. Berger scores of self-acceptance were significantly related to judges' ratings of self-acceptance in the group-discussion situation. Verbal conditioning of self-accepting responses on the Berger scale significantly increased judges' ratings of self-acceptance for those Ss who showed a high level of conditioning.

Application of gel permeation chromatography to the study of shear degradation of polymeric viscosity index improvers used in automotive engine oils

Gel permeation chromatography (g.p.c.) was used to monitor the degradation of polymeric viscosity index improvers in multigrade oils when subjected to mechanical shear using a Kurt Orbahn diesel injector rig. These tests are normally evaluated by measurement of viscosity of the oils before and after shear. For model systems of a base oil containing each of ten viscosity index improvers there is good correlation between viscosity and chromatography results. Tests on a multigrade oil subjected to sonic shear showed that g.p.c. can be used to follow qualitatively the degradation of one polymeric additive in the presence of another.     

Household trials with very small samples predict responses to nutrition counseling intervention

Household trials were conducted to test the acceptability and feasibility of the recommendations to be delivered to the mothers in the context of a randomized intervention implemented in Pelotas, Brazil. A first home visit was paid to assess child health and feeding problems. In a second visit, the mother was encouraged to select one or two recommendations to try out over five days. The last visit was used to assess the mothers' experiences in attempting to implement the recommendations. Nonexclusive breastfeeding, use of the bottle, monotonous diet, and low energy density of foods were the most common problems. The most frequently selected recommendations were those aiming to increase the energy density of foods. Mothers generally reported positive responses to the recommendations. The household trials highlighted the acceptability and feasibility of the planned recommendations and correctly predicted the changes that were successfully implemented by the mothers in the large intervention study.
