Differential growth in estuarine and freshwater habitats indicated by plasma IGF1 concentrations and otolith chemistry in Dolly Varden Salvelinus malma.

This study employed a combination of otolith microchemistry to indicate the recent habitat use, and plasma concentrations of the hormone insulin-like growth factor 1 (IGF1) as an index of recent growth rate, to demonstrate differences in growth and habitat use by Dolly Varden Salvelinus malma occupying both freshwater and estuarine habitats in south-west Alaska. Extensive sampling in all habitats revealed that fish had higher IGF1 levels in estuarine compared to lake habitats throughout the summer, and that the growth rates in different habitats within the estuary varied seasonally. In addition, otolith microchemistry indicated differentiation in estuarine habitat use among individual S. malma throughout summer months. Although growth in the estuary was higher than in fresh water in nearly all sites and months, the benefits and use of the estuarine habitats varied on finer spatial scales. Therefore, this study further illustrates the diverse life histories of S. malma and indicates an evaluation of the benefits of marine waters needs to include sub-estuary scale habitat use.

Perceptions of sex-role stereotypes, self-concept, and nursing role ideal in Chinese nursing students.

AIM: This study examined the relationship between sex-role stereotypes, self-concept and the requisite personality characteristics of an ideal nurse in a cohort of Hong Kong nursing students. METHODS: To rate these concepts a measure of eight comprehensive dimensions of personality perception was administered to 177 nursing students, studying on preregistration and postregistration programs at a Hong Kong tertiary institution. Both male and female nursing students perceived an ideal nurse to possess a profile of traits including being high on the dimensions of emotional stability, application, intellect, helpfulness and restraint. RESULTS: No significant difference between the self-ratings of the male and female students was found, indicating that male students had undergone a highly self-selective process when choosing nursing education under the influence of Chinese cultural stereotypical attitudes towards nursing. A typical Chinese nurse was rated as similar to the typical female in Chinese society by both male and female nursing students. A typical Chinese nurse was rated relatively low on the masculine dimensions of openness, extroversion and assertiveness. The self-ratings of male nursing students more closely approximated the ideal nurse than did the self-ratings of female nursing students. CONCLUSION: The conclusions highlight implications for the recruitment and education of both male and female nursing students in Hong Kong society.

Interpreting personality profiles across cultures: bilingual, acculturation, and peer rating studies of Chinese undergraduates.

Prior research (R.R. McCrae, P.T. Costa, & M.S. Yik, 1996) using a Chinese translation of the Revised NEO Personality Inventory suggested substantial differences between Hong Kong and North American undergraduates. Study 1, with a sample of bilingual Hong Kong students (N = 162), showed that prior findings were not due simply to the translation. Study 2, with undergraduates of European and Chinese ancestry living in Canada (N = 633), suggested that more of the differences were cultural in origin. Study 3, which used peer ratings of Chinese students (N = 99), replicated most Study 2 results, suggesting that exposure to Canadian culture increased openness, cheerfulness, and prosocial behavior and attitudes. Differences in sense of competence and vulnerability to stress appeared to be due to different cultural standards for judging these traits. Together, the 3 studies illustrate an integrated approach to interpreting personality differences across cultures.

Pancultural explanations for life satisfaction: adding relationship harmony to self-esteem.

The first part of the study confirmed an additive effect of the newly proposed construct of relationship harmony to self-esteem in predicting life satisfaction across student samples from the United States and Hong Kong. As predicted from the dynamics of cultural collectivism, the relative importance of relationship harmony to self-esteem was greater in Hong Kong than in the United States. In the second part of the study, the independent and interdependent self-construals (H. R. Markus & S. Kitayama, 1991) and the 5 factors of personality (P. T. Costa & R. R. McCrae, 1992) were advanced to be the culture-general determinants of life satisfaction, acting through the mediating variables of self-esteem and relationship harmony. Both self-construals and the 5 factors of personality were shown to influence life satisfaction through the mediating agency of self-esteem and relationship harmony in equivalent ways across these 2 cultural groups.

Cross-cultural social and organizational psychology.

This review considers recent theoretical and empirical developments in cross-cultural studies within social and organizational psychology. It begins with a description of the importance and the difficulties of universalizing psychological science. It then continues with an examination of theoretical work on both the internal-proximal and the external-distal constraints that mediate culture's influence on behavior. Influences on social cognition are documented by describing research on self-concept, self-esteem, emotions, attribution processes, person perception, interpersonal attraction, and justice. Group processes are addressed in the areas of leadership, decision-making, and negotiation, and research in organizational psychology is examined with respect to work motivation and work behavior. The review concludes that considerable improvement is evident in recent cross-cultural research. However, future research must include a broader range of cultures and attend more closely to the levels at which cultural effects should be analyzed, and cultural samples must be unpackaged in more psychologically useful ways.

Exploring implicit personality theories with indigenous or imported constructs: the Chinese case.

This study is concerned with the relation between indigenous and imported constructs of personality perception. A pool of Chinese personality descriptors was used by Chinese Ss to rate a variety of target persons. These same Ss then rated the same target persons using the (translated) personality descriptions first isolated by Tupes and Christal (1961) from Americans. Five factors of personality perception were then derived from both the emic Chinese descriptors and the imported American descriptors. The interrelations among these factors were examined to address the basic question of how adequately the factors gleaned from these foreign materials represented Chinese perceptual space. Of the 5 Chinese factors, 4 could be adequately explained by varying combinations of the 5 imported factors. Furthermore, there was a 1-to-1 relation of imported to indigenous factors for only 2 of the 5 indigenous factors, whereas the others were multiply determined. The implications of these results are discussed with respect to the widespread use of foreign instrumentation and the models of man that may or may not be constructed in consequence.

Targets of gazing and eye contact during interviews: effect on Japanese nonverbal behavior.

The gaze direction of both the subject and his interviewer were varied independently, such that either looked at the other's eyes or at the other's knees in a 2 X 2 design. A repeated measures design was used with nonverbal vehaviors of Japanese manes as dependent variables. When the interviewers gazed at the subjects' eyes, the response latencies of the subjects were shortened and their torso movements were reduced. Results from other studies of Japanese nonverbal behavior suggest that this pattern of response indicated greater subject invlovement in the interaction. The magnitude of these effects was unchanged whether the subject was reciprocating the interviewer's gaze and making eye contact or looking at the interviewer's knees. It was thus reasoned that effects produced by eye contact in other research may have resulted from subjects' knowledge that they were being gazed at and not from the unique properties of eye contact. When the subjects gazed at the interviewer's eyes, the hand self-manipulations of the subjects increased, reflecting the upsetting effects of monitoring the interviewer's face during interaction. The consequences of gazing at another's eyes thus appear to be different from having one's eyes gazed at by another.
