Influence of client race on counselors' assessment of case materials.

Determined whether racial labels contribute to counselors' assessments of clients. 86 graduate students from 6 counseling programs read and assessed 8 intake case summaries. Four summaries were used in the computation of data. For 1 group of counselors, the clients in those 4 summaries were labeled Black, for a 2nd group they were labeled White, and for a 3rd group there were no racial labels. The counselors rated the cases on 11 positive-to-negative dimensions. Analysis of counselors' ratings summed across cases indicated that Black-labeled cases were rated significantly more positive than those labeled White or with no label. A stepwise multiple regression using the no-label condition as a relative reference point indicated that in the final regression equation, Black-labeled cases contributed more to the prediction of counselors' ratings than level of counseling experience, level of physical social distance to minorities, or prior contact with minorities. Counselors seemingly overcompensated to avoid negative professional bias. The reverse biases they demonstrated are discussed as well as the implications for counseling minorities.

Steam reforming of methanol over ruthenium impregnated ceria,alumina and ceria–alumina catalysts

The wet impregnation method was used to prepare different ruthenium promoted Ce–Al catalysts. These catalysts were used in the steam reforming of methanol reaction (SRM). The effects of the reaction temperature (200–400 C) and the catalyst composition were studied for optimization reasons. The steam to methanol molar ratio was kept constant (S/M = 2). The promotion of cerium/aluminum oxides with Ru enhanced their catalytic activity. The catalytic test results showed that the Ru/Ce combination was the most beneficial. The synergy between Ru and cerium oxide led to the formation of active sites with excellent redox properties. For high active phase content, the 5 RuCe catalyst exhibited the highest hydrogen production amount with no CO formation. This catalyst was kept under stream for 5 days at 400 C, and no significant deactivation was observed. Copyright © 2016 John Wiley & Sons, Ltd.

Approximate reasoning with linguistic modifiers

We analyze the influence of some usual linguistic modifiers, such as scalar product, normalization, Bouchon-Meunier modifiers, perturbation, and (weakening and reinforcement) power, in the process of approximate reasoning and clarify the difference between the conclusions of fuzzy modus ponens in which linguistic modifiers appear and do not appear in premises. © 1998 John Wiley & Sons, Inc.     

Dynamic Features of the Rumen Metabolism of Linoleic Acid,Linolenic Acid and Linseed Oil Measured in Vitro

The lipid quality of ruminant products is largely determined by the extent of rumen microbial biohydrogenation (BH) of polyunsaturated fatty acids (FAs) and the substances formed thereby. In vitro batch incubations with mixed rumen bacteria were tracked over 24 h to characterize the profiles and kinetics of the BH products from three lipid sources: pure linoleic acid (c9,c12–18:2), pure linolenic acid (c9,c12,c15–18:3) and linseed oil (mainly c9,c12,c15–18:3 in triacylglycerols). After 24 h of incubation biohydrogenation was more complete for c9,c12–18:2, which gave mainly stearic acid (18:0), than for c9,c12,c15–18:3, which yielded mainly trans-18:1 FAs. This suggests inhibition of the final BH step (18:1 to 18:0). Incubations of c9,c12–18:2 resulted in high levels of carbon 10- and 12-desaturated 18:1, t10,c12- and c9,t11-CLAs. Incubations of c9,c12,c15–18:3 resulted in high levels of t11–18:1, carbon 13- and 15-desaturated 18:1 as well as t11,c15–18:2 and 11,13-CLAs. A comparative study of linolenic acid and linseed oil kinetics revealed that the BH process was not significantly slowed by the esterification of polyunsaturated FAs, but may have been limited by the isomerization step in which the cis12 double bond goes to the trans11 position. The disappearance rates of c9,c12–18:2 and c9,c12,c15–18:3 ranged from 23.6 to 44.6%/h. The wide variety of BH intermediates found here underlines the large number of possible BH pathways. These data help provide a basis for dynamic approaches to BH processes.     

Perception of variability in category development: Instance- versus abstraction-based stereotypes.

We conducted two experiments to investigate the acquisition and representation of social categories, with an emphasis on the perception of variability of group members. In Experiment 1, subjects learned about a group that was sociable and intelligent and either high or low in variability with respect to these attributes. Differences in the actual variability of group members were reflected in subjects' estimates of variability, in their tendency to generalize from the traits and goals of a single member to the entire group, and in their classification judgments of new instances, which reflected their expectations of group members' future behavior. Memory for instances of the category also played a role in these judgment tasks. In Experiment 2, subjects who first learned about the behaviors performed by group members and then about general characteristics of the group perceived the group as more variable than did those who learned the same information in the reverse order. In both experiments, we manipulated memory for specific behaviors such that either the most extreme behaviors or behaviors at the center of the distribution were most memorable. This manipulation did not affect estimates of perceived variability, suggesting that these were constructed and stored on-line rather than from a retrieved set of category exemplars.

Trance logic in hypnosis and imagination.

Investigated, in 2 experiments, trance logic, or the tolerance of logical incongruity, in age regression and hallucination. Exp 1 tested 21 hypnotizable and 19 unhypnotizable Ss in an application of the real-simulating model of hypnosis. Exp 2 tested 26 high and 19 low imagery ability Ss in an adaptation of the model to the imagination context. Ss' experiences were investigated through the experimenal analysis technique. More real than simulating Ss displayed trance logic during age regression, but they did not differ on the major measures of trance logic during hallucination. This pattern of responding occurred in both the hypnosis and the imagination contexts. Ss' comments suggested that completeness of and belief in age regression or hallucination may play some role in trance logic. The importance of understanding trance logic from the S's point of view is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
