Ethics for all: Differences across scientific society codes

Ethics codes of a number of scientific societies across different disciplines promulgate ethical standards for responsible conduct in research and other professional activities. The content of these codes of ethics are compared on key dimensions of research, service or practice, and teaching in terms of the range and specificity of the activities these codes cover, and in the degree to which they are educational, aspirational or regulatory in purpose. The role of professional associations in educating, regulating, monitoring, and sanctioning their membership is also discussed. An earlier version of this paper was presented at the AAAS-Office of Research Integrity (ORI) meeting in Washington DC on the theme: “The Role and Activities of Scientific Societies in Promoting Research Integrity” held on April 10–11, 2000.     

Measuring Attitudes Toward Acceptable and Unacceptable Parenting Practices

This study investigated the properties of a new rating instrument, the Parenting Questionnaire (PQ), designed to measure attitudes about acceptable and unacceptable parenting practices. In Study 1, subject matter experts representing culturally diverse psychologists, parents, and college students were consulted to identify 110 items receiving high endorsement. In Study 2, items were administered to 1,398 undergraduate students to examine their factor structure and the effects of ethnicity and gender differences on PQ factors. In Study 3, test–retest reliability (N = 92) and convergent validity (N = 142) of the PQ factors were examined. Exploratory factor analysis revealed three factors (total of 63 items) with high internal consistencies that accounted for a moderate amount of total variance (R ² = .38). The factors were Critical Feedback (26 items), Supportive Feedback (26 items), and Physical Discipline (11 items). Significant ethnicity and gender differences were found on the three PQ factors, as well as a significant interaction between ethnicity and gender on the Supportive Feedback factor. PQ factor scores demonstrated good temporal stability, internal consistency, and convergent validity. Overall findings suggest that the PQ is a reliable, stable, and valid measure of attitudes toward parenting with three distinct factors. Future research directions with parents are discussed.     

Role of Zr on growth kinetics and microstructural evolution of the superconductor V3Ga by the bronze technique

The influence of Zr on the growth of V₃Ga is studied by a diffusion-couple technique mimicking the bronze method for superconductor production. Systematic quantitative evaluation on critical-current-density-dependent metallurgical parameters is addressed. A mixture of V₃Ga and Zr-containing phases develops at the interdiffusion zone. Smaller grains on Zr addition cause higher growth kinetics owing to grain-boundary diffusion of Ga. The grains are oriented randomly irrespective of Zr addition. Refined microstructure, second-phase, and higher growth kinetics suggest a beneficial role of Zr for the better functioning of the superconductor.     

Socio-culturally induced distress among migrant labourers in India: a qualitative inquiry

The present study has explored the experiences of distress among Indian migrant labourers with the help of qualitative method. The data were collected using a semi-structured interview schedule where 40 unskilled migrant labourers, 20 males and 20 females participated in the study. The obtained data were analysed using constructivist grounded theory. Findings have given an insight of the dialects (idioms of distress) used by migrants to express their distress. Further, findings divulged that the essence of the migrant labourers’ distress is largely rooted in their culturally defined roles, prevailing socio-cultural norms, apathy of legal and structural system to address their needs and to protect their rights in the host culture (place of migration). The findings draw our attention to design health intervention programmes for migrant and immigrant communities, in India as well as across the world, that amalgamate the elements of collectivistic culture in order to ensure the complete social, psychological, and physical wellbeing of above said communities.     

Vacancy wind effect on interdiffusion in a dilute Cu(Sn) solid solution

A study has been conducted on a Cu(Sn) solid solution to examine the role of the vacancy wind effect on interdiffusion. First, the interdiffusion and the intrinsic diffusion coefficients are calculated. The trend of the interdiffusion coefficients is explained with the help of the driving force. Following this, the tracer diffusion coefficients of the species are calculated with and without consideration of the vacancy wind effect. We found that the role of the vacancy wind is negligible on the minor element in a dilute solid solution, which is the faster diffusing species in this system and controls the interdiffusion process. However, consideration of this effect is important to understand the diffusion rate of the major element, which is the slower diffusing species in this system.
