Subjective well-being is heritable and genetically correlated with dominance in chimpanzees (Pan troglodytes).

The hypothesis that subjective well-being (SWB) is heritable and genetically correlated with Dominance was tested using 128 zoo chimpanzees. Dominance was a chimpanzee-specific personality factor including items reflecting Extraversion and low Neuroticism. SWB was measured with a 4-item scale. The best behavior genetic model included additive genetic and nonshared environmental effects for SWB and Dominance, marginal maternal effects for SWB, a high genetic correlation, and a low nonshared environmental correlation. Results indicated that the shared variance between SWB and Dominance was a consequence of common genes and that the unique variance between SWB and Dominance was a consequence of the nonshared environment. These findings indicate that common genes may underlie the correlation between human personality factors and SWB. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The influence of dietary lipid source on quality characteristics of raw and processed chicken meat

The influence of dietary lipid source [animal fats (AF) and vegetable oils (VO)] on quality characteristics of raw chicken meat (breast, thigh and meat batter) and cooked breaded patties prepared using a conventional technology (CT; forming, battering, breading, frying and convection cooking) or innovative technology (IT; forming, pre-dusting, steam cooking, battering and frying) was evaluated. Overall, dietary lipid source did not influence the chemical composition of raw meat while it modified its colour (L*, a*, b*). With respect to AF, VO produced higher breast and thigh meat cooking losses as well as a lower moisture and higher protein content of cooked breaded patties. VO also determined an increase of polyunsaturated-to-saturated fatty acid ratio of both raw and processed meat. Despite the different fatty acid profiles, the oxidative status of lipids was not affected by dietary lipid source and was acceptable in both raw meat and cooked patties as indicated by peroxide and thiobarbituric acid reactive substance values. As for the processing technology, IT determined a higher moisture and lower lipid content of the cooked breaded patties. Moreover, lipolysis degree was slightly higher in the products coming from IT. Finally, patties from AF group were lighter and more yellow than products belonging to VO group whereas IT led to lighter, less red and more yellow patties in comparison to CT.     

Comparative study of reactivity and agronomic effectiveness of Indian,US, African and Middle East rock phosphates for growing rice

Comparative reactivity and efficiency of eight Indian, six US, two African and one Middle East sources of rock phosphates for growing rice on laterite, red and alluvial soils under flooded conditions were evaluated in pot and laboratory experiments. When applied to moist aerobic soils, 15 days prior to flooding and transplanting rice, all the Indian sources were as poor as theno phosphate control in the three soil types, in respect of P availability in soil, grain yield response and P uptake by rice. North Carolina rock phosphate used in this study was as good as superphosphate in the laterite and red soils, but was also as poor as control in the black soil.NH₄ -citrate was found to interfere in the colorimetric determination of citrate soluble P by the vanado-molybdate colour method. A modified sulpho-molybdate-Sn Cl₂ blue colour method could successfully be used to determine 2–8µg P in the presence of 0.02 to 0.2 meq NH₄ -citrate, especially in rocks containing small amounts of citrate soluble P. All the Indian, as well as Idaho, Missouri and Tennessee rock phosphates were found to be less reactive as they contained much lower amounts of citrate extractable P in eight successive extracts as compared to North Carolina rock phosphate.The cumulative citrate soluble P of 10 rock phosphates determined experimentally in eight successive extracts was significantly correlated with their reported a₀ (length of a axis of unit apatite crystal), mole ratio of CO₃/PO₄ or weight ratio of F/P₂O₅ of rocks. In the absence of X-ray and computer facilities, these regression equations were used to calculate the a₀, CO₃/PO₄, F/P₂O₅, ACS, empirical formula and the apatite content of the unknown Indian rock samples. The Indian rock phosphates had a lower degree of CO₃ and F substitution for PO₄ in the apatite crystal, giving low ACS values and hence were less reactive. This might explain their lower efficiency for direct application for growing rice, obtained in the present experiment. These Indian rock phosphates had also lower apatite content. The use of the statistical method was limited to francolites alone. Scope for the use of this method for other unknown francolite rock phosphate samples has been discussed.     

"Gender characteristics and adjustment: A longitudinal study": Addendum.

Reports an error in "Gender characteristics and adjustment: A longitudinal study" by Jennifer Aubé and Richard Koestner (Journal of Personality and Social Psychology, 1992[Sep], Vol 63[3], 485-493). The authors would like to acknowledge that the age 41 longitudinal data used in their study were collected by David McClelland, Carol Franz, Joel Weinberger, Richard Koestner, and Joseph Healy. This data collection was supported by a grant from the Seaver Institute. The data are currently being archived at the Henry Murray Research Center of Radcliffe College, Cambridge, Massachusetts. (The following abstract of the original article appeared in record 1993-01033-001.) Used a prospective longitudinal design to investigate the long-term developmental implications of gender-related interests and traits. Archival data were available for Ss in the R. R. Sears et al (1957) study. Men, who at age 12 yrs endorsed interests and undesirable traits more typically associated with women, had poorer social–personal adjustment at ages 31 and 41 yrs. No effects were found for women. Feminine expressive traits at age 31 yrs did not impact on 41-yr-old adjustment for either men or women, whereas masculine instrumental traits were positively related for both. These findings support a multidimensional view of gender and indicate that harsher consequences follow when adolescent boys endorse nontraditional gender-related interests and undesirable traits than when girls do so.

Review of Improving productivity through performance appraisal.

Reviews the book, The New Partnership: Women and Men in Organizations by Nina L. Colwill (1982). The stated goals of this book are "to increase awareness" of: a) sex-role problems in organizations, b) some potential solutions, and c) relevant research evidence. An unstated but evident goal is to persuade the reader that women, men, and organizations will all benefit from the maximal development of both sexes' potential. The book contains nine chapters, four of which are co-authored with others expert on the chapter topic. The broad range theory and research presented deals with attitudes, roles, traits and abilities, achievement and related attributions, power, communication, and groups and leadership. Each subject area is initially viewed broadly with a subsequent focus on special issues and research results relevant to sex discrimination in organizations. At the end of each chapter is a section dealing with "alternatives for change" and a set of exercises for use in groups, individually, in interviews, and in designing a study.

Personality and product use.

The answers to the Gordon Personal Profile and a disguised product use questinnaire by 101 college of business students demonstrate that personality traits are often related to product use. Thirteen of a possible 36 such relations were significant at the .05 level or above. A corollary conclusion is that the Gordon Personal Profile distinguishes personality traits related to behavioral differences, although the four traits are not "independent."

Forty years on: Teachers' assessments of children's personality traits predict self-reported health behaviors and outcomes at midlife.

A life span health-behavior model was investigated in this longitudinal study of personality influences on health. Teachers assessed 963 elementary schoolchildren on traits that formed scales assessing the dimensions of the five-factor (Big Five) model of personality. Smoking, alcohol use, body mass index (BMI), and self-rated health were assessed 40 years later in midlife. Childhood personality traits were significantly associated with all 4 outcomes, and the effects were consistently larger for women than men. For men and women, childhood Conscientiousness was associated with less adult smoking and better adult self-rated health and, for women only, with lower adult BMI. Mediation analyses suggested that the effects of Conscientiousness on self-rated health were partially mediated by smoking and BMI. These findings add to the growing evidence that childhood personality traits predict adult health outcomes and are discussed in terms of future testing of the life span health-behavior model.

Neurotic differences between individualized and socialized criminals.

This study sought to demonstrate that neurotic differences could be found among prison inmates chosen according to characteristics of their criminal behavior. 3 groups of 15 white, male, prison inmates were screened from a prison's total population. An individualized group, whose crimes were violent, aggressive, and lacked a financial motive, were found to show significantly different elevations (at the .05 and .01 levels) from the other groups on several subscales of the MMPI and the CPI. These results reflect more neurotic traits in the individualized group than in the more common socialized criminal groups. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The measurement of leadership in white and Negro women students.

A comparison of personality traits and other characteristics of leaders and non-leaders in two southern colleges for women, Agnes Scott for white and Spelman for Negro students, is made. The materials used are the Good-enough Speed-of-Association Test, the Bernreuter Personality Inventory, and other collateral information. Small, but statistically significant, differences exist between leaders and non-leaders within a college. These differences are "definitely and reliably greater than are the differences between the two races." (PsycINFO Database Record (c) 2010 APA, all rights reserved)
