The use of the MMPI in the selection of hospital aides.

MMPIs were administered to 2700 applicants for the position of psychiatric aide in an institution for the mentally retarded. MMPI subscale scores of all persons hired and subsequently discharged were compared with groups of like sex who: (a) were hired in the same year but resigned for reasons not associated with the job, (b) stayed in the employment of the institution, or (c) were not hired. No single subscale differentiated between the groups. The few differences which were found between the groups when a variety of configurational analyses were used did not reappear in a cross-validation sample. Conclusion: the hypothesis that personality test scores are related to the competency of psychiatric aides was not supported. From Psyc Abstracts 36:05:5LD34B.

In vivo determination of the stress-strain relation of the human myometrium

Effects of L-glutamine on gastric lesion models in rats and guinea pigs were studied. Shay ulceration in rats was not inhibited by oral L-glutamine. Although stress-induced gastric lesions in intact rats were not inhibited by L-glutamine, a strong antagonism of gastric lesions was induced in pylorus-ligated rats under the same stress by the amino acid. Histamine-induced gastric lesions in intact rats and guinea pigs were also markedly inhibited by L-glutamine. L-Glutamine inhibited the gastric lesions in rats induced by compound 48/80 but not significantly. Reserpine- or serotonin-induced gastric lesions in rats were not affected by L-glutamine. The mechanism of L-glutamine protection was discussed.     

Some determinants of job satisfaction: A study of the generality of Herzberg's theory.

This paper criticized the Herzberg theory that certain work-situation variables ("satisfiers") produce positive, but not negative, job attitudes, while other variables ("dissatisfiers") produce negative, but not positive, job attitudes. Several deficiencies in the methodology of the Herzberg study were discussed. There were: the narrow rang of jobs investigated, the use of only 1 measure of job attitudes, the absence of any validity and reliability data, and the absence of any measure of overall job satisfaction. It was concluded that generalizing the Herzberg results beyond the situation in which they were obtained is not warranted. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Transforamtion of twitching strains of Streptococcus sanguis

Ninety-five strains of S. sanguis, 90 of which were twitching, were screened for competence in transformation with DNA from the "Challis" strain. Seventy-two strains, 68 of sero-group H and 4 of the provisional group 10043, were competent. Fourteen of the competent strains and all strains which appeared to be incompetent were tested with DNA from 3 other strains. The 14 competent strains were transformed by all the 3 DNAs. One of the apparently incompetent strains was transformed by autologous DNA only. Among 8 reference strains (including ATCC 10577, Type II of Washburn et al.) 5 were competent. Three of these did not show spreading or twitching. Among 16 non-spreading strains of alphahaemolytic streptococci which did not possess either the H or the 10043 group antigen, only one showed competence. The results indicate that twitching mobility is not a prerequisite for competence.     

Effect of high dietary copper on fatty acid composition of the chick

Three experiments were conducted to study the effect of varying levels of dietary copper on fatty acid composition of adipose and liver tissue of male broiler chicks. Chicks were fed the experimental diets to 4 weeks at which time leg adipose and liver samples were obtained for fatty acid determination. Adding 500 or more p.p.m. copper to either a practical or corn starch-soy basal diet caused significant changes in fatty acid composition but the differences were variable perhaps due to a depression of growth caused by these levels of copper. Fatty acid composition of the tissue was not greatly affected by adding 250 p.p.m. of copper to the practical diet which contained 1.5% poultry fat. When a corn starch-soy diet was fed with 0, 2, or 8% added corn oil, the ratio of 16:0 + 18:0 to 16:1 to 18:1 was not lowered in leg adipose lipids by copper supplementation (250 p.p.m.) with any level of added corn oil. With liver lipids copper appeared to reduced the ratios in birds fed the diets with 0 or 2% added corn, but the differences were not statistically significant. The results indicate that using copper levels in practical diets that do not depress growth rate will not have much effect on fatty acid composition of carcass lipids and probably not on physical characteristics of the fat.     

Cardiac effects of sumatriptan: findings of Holter monitoring and review of the literature

The aim of this study was to elucidate possible electrocardiographic effects of sumatriptan in a selected group of patients with severe headache requiring in-patient treatment. The patients (n = 21) were treated with sumatriptan in addition to various other compounds and were asked to record any symptoms following the administration of sumatriptan. In addition, Holter monitoring was performed in all subjects. In agreement with other studies, the adverse events reported by the patients were not related to ECG changes and, vice versa, ECG changes were not accompanied by clinical symptoms. The Holter findings before and after administration of sumatriptan were significantly different in three patients, i.e. recurrent episodes of ST depression and increase in extrasystoles. These changes occurred within a period of 1.45 to 18 hours and were not reproducible when Holter monitoring was repeated without sumatriptan. Even though the findings might be explained by spontaneous variability of Holter monitoring or other factors, this study does not definitely discount the possibility that sumatriptan may cause ST segment changes and increase pre-existing extrasystoles. Controlled studies are required to clarify this issue.     

An assessment of some structural properties of the Jungian personality typology.

Some structural properties of Jung's typology were investigated, using a self-report inventory, the Myers-Briggs Type Indicator. The findings were that: (a) the type classifications had moderate stability; (b) indicator score distributions were not bimodal; (c) with one exception, the regressions of other variables on indicator scales did not change at the zero point of the indicator scales; (d) the indicator scales did not interact; (e) the indicator scales did not moderate the regressions of other variables on one another; and (f) type indeterminacy was unrelated to ineffective behavior and maladjustment. It was concluded that these results offer little support for any of the structural properties attributed to the typology. (33 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychosocial, cultural, and accessibility factors associated with participation of African-Americans in rehabilitation.

Examined the association among psychosocial, cultural, and accessibility factors and participation of Blacks in the rehabilitation process. 186 Ss with disabilities were surveyed. Ss were categorized into 1 of 2 groups corresponding to whether or not they were currently receiving rehabilitation services. Histories of level of participation in the rehabilitation process were also obtained. Perception of service provider capability, self-esteem, emotional support, and attitude toward seeking and receiving services were significant predictors of whether or not Ss were in the current rehabilitation group. Whether or not client/service providers were of the same race/ethnic group, perception of service provider capability, and attitude toward employment were significant predictors of whether or not Ss participated in periodic or more continuous rehabilitation.
