The microstructure of fluidizable cracking catalysts

The characteristic morphologies of components used to prepared fluidizable cracking catalysts have been identified informed microspheres by a scanning electron microscope-energy dispersive X-ray analyser system. Differences in preparation methods and materials are observed in the catalyst microstructure. Cracking unit processes and laboratory simulation experiments result in changes in catalyst morphology. The relationships between cracking catalyst microstructure and performance are discussed in this paper.     

Edge- and end-pumped slab lasers with both efficient and uniform pumping

In conventional high-power slab lasers, the design is often a compromise between pump absorption efficiency and uniformity. In this paper, both are studied for diode-array-pumped slab lasers. We explore a method with which each can be separately optimized, so it becomes possible to have both high efficiency and uniformity in slab lasers with long optical pump paths. The method is applicable to composite and ceramic crystal slab lasers.     

Issues involved in relations between methodological rigor and reported outcomes in evaluations of organizational development.

D. E. Terpstra (see record 1982-04524-001) found that organizational development (OD) was more likely to be positively evaluated by less rigorous research. It is suggested that Terpstra's findings raise issues concerning investigator bias, and differences in research objectives, or differences of short-term or long-term interests. Some OD proponents may be more swayed by a collective weight of evidence, in a Bayesian sense, whereas opponents may be influenced by the quality of individual studies. There is also the paradox that the less rigorously results are obtained, the more likely they are to be implemented by management.

Validity studies of a proverbs personality test.

Data from twenty samples including 282 salesmen, 78 factory supervisors, 49 public school teachers, 147 penitentiary inmates, 34 Marine Corps enlistees, 361 college students, 36 student nurses, and 234 high school students were used in a correlation analysis of a three-factor list of proverbs from the Famous Sayings Test. "Low positive correlations with corresponding measures and educational and occupational group differences tend to sustain the supposition that three content factors—Conventional Mores, Hostility, and Fear of Failure—are assessed by the three scales. The factors, as measured, do not appear related to academic overachievement, psychopathy, or success as a salesman. However, the Fear of Failure Scale may have some utility for the forecasting of success as a factory supervisor." (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Team creativity as a function of the creativity of the members.

The relationship between team performance and individual abilities was studied with creative tasks. Data from 3 experiments are presented which indicate that the conclusions of other investigators, who used manual dexterity and cognitive tasks, can be applied to creative tasks. Up to about 70% of the variance in dyadic creativity may be predicted from the individual creative abilities of the 2 members. Multiple correlations for the prediction of group performance from the knowledge of the abilities of the members did not improve when the interaction between the ability scores was considered. In 1 experiment, in which the procedure permitted the determination of the relative "dominance" of the 2 Ss, the correlations of the abilities of the dominant Ss with group performance were higher than the correlations of the abilities of nondominant Ss with group performance. The study is a 1st step towards the determination of the relationship of group and individual performance in groups composed of more than 2 individuals.

Environmental psychology.

Comments on H. M. Proshansky's (see record 1976-21564-001) article on environmental psychology (EPSY) and proposes that EPSY involves the study of the individual interacting with the physical world, both natural and built. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Electrooptic Q switching of the Nd:YVO4laser without an intracavity polarizer

An explanation of the excellentQ-switched lasing of Nd:YVO4at pump levels many times threshold with no intracavity polarizer is presented. A small wedge between the laser rod's end faces, coupled with the material's high birefringence, enables the rod to act as its own intraeavity polarizer. This results in a simplification of theQ-switched optical resonator and can be applied to other birefringent laser materials.     

Observation of microwave beats in a parallel-plate transmission-line photomixer

A parallel-plate transmission-line photomixer has been used to produce microwave beats at frequencies up to 30?40 Gc/s. These were derived by photoelectric mixing of the optical modes of a ruby laser.     

Management styles associated with organizational, task, personal, and interpersonal contingencies.

Prior studies with subordinates and managers from public and private agencies resulted in the development of a 31-scale profile questionnaire conceptualized in a systems framework of input, transform, and output variables. In the present study, the profile was completed by 78 managers and 407 of their subordinates. Convergent and concurrent validity studies generally supported the validity of the scales. 5 management styles measured were found to be conceptually but not empirically independent. The styles--direction, negotiation, consultation, participation, and delegation--differentially correlated with organizational, task, intrapersonal, and interpersonal variables, as well as with measures of work-unit effectiveness and satisfaction. According to stepwise regressions, direction was most likely to appear with structure and clarity; negotiation with short-term objectives and authoritarian subordinates; consultation, with long-term objectives and intragroup harmony; participation, with clarity and warmth; and delegation, with warmth and lack of routine tasks.

Faking by sales applicants of a forced choice personality inventory.

The Gordon Personal Profile was given to 265 sales employees of a food distributor, and to 471 employment applicants. Applicants scored significantly higher than employees on all scales. "Applicants practically never earn a minus value on any response while employees often do. Applicants never indicate as most like themselves some derogatory alternative in a tetrad… . Greater range in response among applicants can be obtained in several ways. For example four complimentary statements can be used in a tetrad of more subtle items."
