Spatial and physical frames of reference in positioning a limb

Splints attached to the right forearm were used to rotate the forearm’s physical reference frame, as defined by the eigenvectors of its inertia tensor, relative to its spatial reference frame. In two experiments, when subjects were required to orient the forearm parallel to, or at 45° to, the environmental horizontal, they produced limb orientations that were systematically deflected from the forearm’s longitudinal spatial axis in the direction of the forearm’s physical axes. The position sense seems to be based on inertial eigenvectors rather than on joint angles or gravitational torques.     

An Evaluation of the Cross-Cultural Validity of Holland's Theory: Career Choices by Workers in India

The current study evaluated the cross-cultural validity of Holland's (1985) theory through internal and external analyses based on the responses of 172 natives of India who completed the Vocational Preference Inventory (VPI) and measures of job and occupational satisfaction. Internal consistency estimates for Holland dimensions, intercorrelations among participants' vocational interest scales, and the results of a randomization test (Tracey, 1997) all provide evidence for the internal structure of the VPI with Indians. However, the VPI did not exhibit high external validity. Further, multiple regression results indicated that congruence, consistency, and differentiation did not predict job or occupational satisfaction, suggesting cross-cultural boundaries on Holland's theory itself. Finally, we assessed and found limited conceptual and linguistic equivalence of measurement of the VPI in India. The assumptions of Holland's theory in light of the current findings are discussed.     

Participants' reactions to “Equity with the world”

According to traditional Equity theory, the injustices that an individual encounters in one relationship should not affect his other relationships. By definition, the equitableness of one relationship (say the AB relationship) depends entirely on how much Participants A and B contribute to the relationship and how much they get out of it.Austin, in Austin and Walster (1973), however, argues that Equity theory must make transrelational predictions. He argues that persons attempt to maintain both “Person-specific Equity” and “Equity with the World” (e.g., Equity with others in general). The authors predicted (and found) that whether a person focuses on “Person-specific Equity” or “Equity with the World” depends on whether or not he feels “accountable” for his behavior. When participants knew they could not be held accountable for their actions, they routinely sacrificed Person-specific Equity in order to maintain Equity with the World. However, when they knew they would have to confront their second partner eventually, they rarely sacrificed Person-specific Equity. (Evidently, they assumed their partners would not sympathize with their desire to maintain transrelational equity.)In this experiment, we predicted (and found) that such pessimism (by persons wishing to restore “Equity with the World”) is not justified. Inequitably treated partners' dissatisfaction and hostility were markedly blunted when individuals believed that their “unfair” partner was attempting to restore “Equity with the World“.     

Longitudinal relationships between workplace bullying,basic psychological needs,and employee functioning: a simultaneous investigation of psychological need satisfaction and frustration

The aim of this cross-lagged study was to provide new insight into the interplay between workplace bullying, basic psychological needs (for autonomy, competence, and relatedness), and employee functioning. Based on new developments in self-determination theory (SDT) research, we simultaneously examined the temporal relationships between workplace bullying, need satisfaction and frustration, as well as two indicators of psychological functioning: life satisfaction and psychosomatic complaints. Data were collected at two time points over a 12-month period from a sample of 508 Canadian nurses. Results suggest that bullying not only negatively predicted satisfaction for the needs of autonomy and competence, it actively frustrated all three needs. Frustration of the needs for competence and relatedness as well as satisfaction of the need for relatedness also predicted the psychological functioning of employees exposed to bullying behaviour over time. Taken together, the results suggest that evaluating need frustration provides in-depth insight into the detrimental effects of bullying on employees’ psychological inner resources and may explain the impoverishment of employees’ psychological functioning when confronted with bullying behaviour. The implications for the bullying and SDT literature are discussed.
