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.     

Integration of Analytic Hierarchy Process with Regression Analysis to Identify Attractive Locations for Market Expansion

Selection of new geographies in which to expand is a key decision for businesses aspiring to go beyond the opportunities in the existing markets. The conventional approaches of market selection can only provide a set of systematic steps for problem solving without considering the relationships between the decision factors. Decision models based on statistical techniques are able to examine the relationship between decision factors but are unable to effectively assist decision makers in identifying the most promising market, particularly in terms of prioritizing across decision factors. Analytic Hierarchy Process (AHP) is a commonly used approach for choosing alternatives by prioritizing across multiple decision factors. The typical AHP modelling requires knowledge of criteria and/or alternatives along with their relative weights, generally elicited from field experts. Quite often, firms encounter situations where decision makers are aware of only the overall objective and a set of earmarked geographies for setting up market locations while being relatively unaware of decision criteria and relative weights. This precludes using AHP to identify promising market locations. This paper conceptualizes a market selection decision model that integrates AHP with statistical modelling techniques to identify the attractive market locations for the purpose of expansion. The model first uses principal component analysis and multiple regression to determine significant decision criteria and their weights. Thereafter, it applies AHP to prioritize the market locations across the decision criteria. This integrative approach is illustrated for identifying the attractive locations in rural markets for a steel firm in India. The major advantage of this approach is that unlike the existing models, it works in situations when firms have not enough knowledge about factors for evaluating alternative market locations. Another key advantage of the proposed model is that of economizing resources for data collection on variables representing decision factors. Copyright © 2012 John Wiley & Sons, Ltd.     

Frank's 'cubic' hexagonal phase: An intermetallic cluster compound as an example

Frank introduced in 1965 the novel idea of projection from a four-dimensional cube to recover the points of a hexagonal lattice with a special c / a ratio of ( 3 - 2 ½. This was called a cubic hexagonal crystal, as there was a similarity to the conventional cubic crystals in that directions were perpendicular to planes with the same Miller-Bravais indices. While a number of crystals in the NiAs-Ni 2 In family have been reported with this special axial ratio, the number of atoms in the unit cell is small. As the first example of an intermetallic cluster compound, we identify µ-Al 4 Mn, µ-Al 4 Cr, Zn-Mg-Sm and a host of related intermetallics featuring a special aggregate of icosahedra as Frank's 'cubic' hexagonal phase or its variant. The metric is generated by the Friauf polyhedra and the icosahedral linkages and leads to a multimetric crystal and several interesting connections with hexagonal quasicrystals, hexagonal phases and derivative orthorhombic and lower-symmetry structures.     

Electron diffraction patterns from the Al–Mn decagonal phase

Abstract

The variety of electron diffraction patterns arising from the decagonal phase has been explored using a stereographic analysis for generating the important zone axes as intersection points corresponding to important relvectors. An indexing scheme employing a set of five vectors and an orthogonal vector has been followed. A systematic tilting from the decagonal axis to one of the twofold axes has been adopted to generate a set of experimental diffraction patterns corresponding to the expected patterns from the stereographic analysis with excellent agreement.     

Effect of lithium-ion irradiation on the crystallization kinetics of glassy Se98In2

Differential scanning calorimetry (DSC) has been used to study the crystallization kinetics of glassy Se₉₈In₂ both before and after irradiation of the alloy with high-energy (50 MeV) lithium ions. After the ion-irradiation, significant changes in the kinetic parameters of crystallization of the glass were observed. The results are explained in terms of a model involving irradiation-induced defects.     

Fracture mechanism of a coarse-grained magnesium alloy during fracture toughness testing

The fracture mechanism during fracture toughness testing has been investigated on a coarse-grained magnesium alloy, with an average grain size of ～50 µm, and a low fracture toughness. The results show that {1012}-type deformation twins are formed at the crack tip and many dislocations pile up on these boundaries. The accumulated strains at these boundaries become the origin of fracture; i.e. cracks propagate along these boundaries between the deformation twins and the matrix.     

Evaluations,Attitude Similarity,and Interpersonal Attraction: Testing the Hypothesis of Weighting Interference Across Responses

The greater effect of negative than positive stimuli on judgments—the positive-negative asymmetry (PNA)—is rather pervasive. However, the effects of the valence of evaluations of the participant by the partner and attitude similarity between them on attraction have been inconsistent with PNA. The hypothesis that the weighting rule instigated by the first response interferes with the weighting rule normally expected for the second response was tested. As hypothesized, evaluations and attitude similarity interacted when attraction response was assessed prior to competence response but not when competence response was assessed first. The effects in the first measured response fully mediated the effects in the second measured response but not vice versa. Implications of the finding for attraction and PNA are discussed.     

Transgender Youth of Color and Resilience: Negotiating Oppression and Finding Support

This qualitative study explored the resilience of 13 transgender youth of color in the southeastern region of the U.S. The definition of resilience framing this study was a participant’s ability to “bounce back” from challenging experiences as transgender youth of color. Using a phenomenological research tradition and a feminist, intersectionality (intercategorical) theoretical framework, the research question guiding the study was: “What are the daily lived experiences of resilience transgender youth of color describe as they negotiate intersections of transprejudice and racism?” The researchers’ individuated findings included five major domains of the essence of participants’ daily lived experiences of resilience despite experiencing racism and transprejudice: (1) evolving, simultaneous self-definition of racial/ethnic and gender identities, (2) being aware of adultism experiences, (3) self-advocacy in educational systems, (4) finding one’s place in the LGBTQQ (lesbian, gay, bisexual, transgender, queer, questioning) youth community, and (5) use of social media to affirm one’s identities as a transgender youth of color. Implications for practice, research, and advocacy, in addition to the study’s limitations are discussed.
