The Influence of Castration on the Constituents of Rat\u27s Liver

Houssay and coworkes showed that the incidence of diabetes in castrated male rats induced by subtotal pancreatectomy is less than in normal ones . Female rats were more resistant to diabetes than male ones, the resistance itself being decreased by castration. The increased resistance of male castrated rats was ascribed to the removal of testicular hormones. The ovarial hormones produced, in subtotally depancreatized rats hypertrophy of insular tissue in which dominated the number of B-cells i. e. the insulinogenic cells

A modern network approach to revisiting the positive and negative affective schedule (PANAS) construct validity

Introduction: The factor structure of the Positive and Negative Affective Schedule (PANAS) is still a topic of debate. There are several reasons why using Exploratory Graph Analysis (EGA) for scale validation is advantageous and can help understand and resolve conflicting results in the factor analytic literature. Objective: The main objective of the present study was to advance the knowledge regarding the factor structure underlying the PANAS scores by utilizing the different functionalities of the EGA method. EGA was used to (1) estimate the dimensionality of the PANAS scores, (2) establish the stability of the dimensionality estimate and of the item assignments into the dimensions, and (3) assess the impact of potential redundancies across item pairs on the dimensionality and structure of the PANAS scores. Method: This assessment was carried out across two studies that included two large samples of participants. Results and Conclusion: In sum, the results are consistent with a two-factor oblique structure.Fil: Flores Kanter, Pablo Ezequiel. Universidad Empresarial Siglo XXI; Argentina.

Gendered self-views across 62 countries: a test of competing models

Social role theory posits that binary gender gaps in agency and communion should be larger in less egalitarian countries, reflecting these countries’ more pronounced sex-based power divisions. Conversely, evolutionary and self-construal theorists suggest that gender gaps in agency and communion should be larger in more egalitarian countries, reflecting the greater autonomy support and flexible self-construction processes present in these countries. Using data from 62 countries (N = 28,640), we examine binary gender gaps in agentic and communal self-views as a function of country-level objective gender equality (the Global Gender Gap Index) and subjective distributions of social power (the Power Distance Index). Findings show that in more egalitarian countries, gender gaps in agency are smaller and gender gaps in communality are larger. These patterns are driven primarily by cross-country differences in men’s self-views and by the Power Distance Index (PDI) more robustly than the Global Gender Gap Index (GGGI). We consider possible causes and implications of these findings

Some socio-demographic and psychological correlates of the achievement motive

Research is dealing with the following: Do men and women differ in level or structure of the achievement motive? Are level of education and age significant factors in differentiation of young concerning the level of achievement motive? Do such values as collectivism/individualism and conservativism/radicalism correlate with the person's tendency to succeed? Sample was 382 men and women, average age of 21 and different levels of education. Scale MOP 2002 (Franceško, Mihić, Bala) has been applied for the achievement motive measurement; level of collectivism/individualism has been measured by KOIN2002 (Kodžopeljić, Šakotić, Janičić) and for the dimension conservativism/radicalism scale KORA2002 (Janičić, Majstorović, Genc) has been used. All scales mentioned have very good metric characteristics. Results show that men and women do not differ significantly concerning the score at the achievement motive scale, but they do differ in two factors that make this motive. Women show more persistency in achieving the aim and more often, compared to men, find pleasure in achieving those aims. Concerning the level of education, only one component (competition) showed relevant differences. Younger and less educated people showed higher tendency to compete. Total score at the MOP2002 scale correlates positively with the total score at the conservativism scale; also, correlation has been found between components of these two dispositions
