Psychopathology in Children with Thalassemia Major

The present work investigated the prevalence and spectrum of psychopathology in children with thalassemia. Childhood psychopathology measurement schedule (CPMS), adapted from Child Behavior Checklist was administered on children with thalassemia major receiving regular blood transfusion. Age and sex matched children with other chronic illness (bronchial asthma) served as controls. 46.7% of children with thalassemia had a CPMS score of > 10 as against 17.1% in the control group. Children with thalassemia had higher scores in factors of conduct problems, special symptoms and somatization. This study highlights the significantly higher psychopathology in children with thalassemia major and emphasizes the need for psychosocial support during treatment.     

Empirical Evaluation of Dimensionality of Organizational Citizenship Behavior for Indian Business Context

Knowledge about dimensionality of Organizational Citizenship Behavior (OCB) is essential for conducting any future research on the construct. The present study explores the suitability of OCB conceptualization developed by Organ (1988) in Indian business context. Confirmatory Factor Analysis (CFA) was performed to test the dimensionality of the 5-factor OCB conceptualization. Based on the results of CFA alternate conceptualizations were explored. A three factor conceptualization consisting of ??organization-orientation??, ??punctuality?? and ??individual-orientation?? factors showed excellent fit with data. Concurrent validity of factors was tested with organizational justice, organizational identification and job tenure. ??Organization-orientation?? and ??individual-orientation?? emerged as significant dimensions of OCB. Implications for theory and practice are discussed.     

Effect of couple stress at the interfaces of a nano-hole on the anti-plane electro-mechanical behavior

In piezoelectric nanocomposites, surface/interface plays an important role in determining the size-dependent behavior of media. Within the framework of couple stress, the effect of surface/interface around a nano-hole on the anti-plane electro-mechanical behavior is examined. By introducing a surface/interface model, the stress and electric displacement effects on the size-dependent behavior are both considered. The governing equations in piezoelectric materials are decoupled into the classical ones. The displacement and electric potential are expressed by Bessel functions. By satisfying the boundary conditions around the hole with the interface/surface effect, the expanded coefficients are obtained. Through analysis, it is shown that the mechanical and electrical fields drastically depend on the relative size of the hole with respect to the characteristic length of the material. The effects of couple stresses on the stress and electric field are also addressed. Comparison with the existing results is also given.     

Understanding the role of social support in trajectories of mental health symptoms for immigrant adolescents

This longitudinal study of 286, urban residing, first- and second-generation immigrant adolescents examined the degree to which acculturative stress is related to the developmental trajectories of mental health problems and the role of social support in this process. Participants were recruited when they entered 10th grade and two additional waves of data were gathered at 12-month intervals. Using individual growth curve modeling, the results show significant decline in internalizing mental health problems during the high school years. At the same time, greater exposure to acculturative stress predicted significantly more withdrawn/depressed, somatic, and anxious/depressed symptoms. Additionally, social support moderated the relation between acculturative stress and anxious/depressed symptoms. Gender and generation status differences were found only at baseline (10th grade).     

Replies to Selim Berker and Karl Schafer

I respond to six objections, raised by Selim Berker and Karl Schafer, against the theory offered in my Empiricism and Experience: (1) that the theory needs a problematic notion of subjective character of experience; (2) that the transition from the hypothetical to the categorical fails because of a logical difficulty; (3) that the constraints imposed on admissible views are too weak; (4) that the theory does not deserve the label ‘empiricism’; (5) that the motivations provided for the Reliability constraint are insufficient; and (6) that convergence is bound to fail since epistemic entitlements are permissions.     

Indian Perspective on Psychotherapy: Cultural Issues

India is in a state of transition between massively transformed ‘modern’ lifestyles on one hand and the influence of traditional values and customs on the other. In view of the current realities of urbanization, migration, globalisation and societal transformation, the mental health treatment needs have become complex. The article highlights the existing mental health issues and traces the development of various psychotherapeutic techniques in India. An effort has been made to look into the basic tenets of the Indian culture which have a bearing on the conceptualisation and practical application of psychotherapy in the Indian setting. The cross-cultural relevance and adaptability of western psychotherapies in multi-ethnic and collectivistic Asian culture are discussed. In view of the differences between the eastern and western approaches to mental health, challenges in culturally-responsive adaptations are highlighted. It is seen that psychological interventions among masses are beneficial if indigenous approaches based on paradigms like themes from Gita, are cross-fertilized with western psychotherapy. However, there is a need to generate empirical evidence for indigenization of psychological treatments.     

Conditionals in Theories of Truth

We argue that distinct conditionals—conditionals that are governed by different logics—are needed to formalize the rules of Truth Introduction and Truth Elimination. We show that revision theory, when enriched with the new conditionals, yields an attractive theory of truth. We go on to compare this theory with one recently proposed by Hartry Field.

Stress, Rewards, and Change in the Centrality of Women’s Family and Work Roles: Mastery as a Mediator

Although research suggests that stress and rewards experienced in a social role are associated with changes in the centrality (or personal importance) of that role over time, little attention has been given to the mechanisms that account for this relationship. This study was conducted to examine change in role mastery as a mediator in the relationship between changes in role experiences (stress and rewards) and changes in centrality among 195 women who simultaneously occupied the roles of parent care provider, mother, wife, and employee. Regression analyses indicated that increases in parent care, mother, and employee stress eroded mastery in those roles. In addition, increases in rewards were associated with a bolstered sense of mastery in each of the four roles. Mastery was found to be a mediating mechanism in the relationship between stress/rewards and centrality in one of the four roles examined, the employee role. However, changes in womens perceptions of mastery were unrelated to the extent to which women changed the importance of their three family roles. These findings extend prior research by demonstrating that mastery is a mechanism through which stress and rewards are associated with centrality in the employee role.
