A new method for automated reconstruction of pre-transformation microstructures

A new method, referred to as the cluster method, is proposed and tested for the reconstruction of pre-transformation microstructure in Ti–6Al–4V alloy. The cluster method begins by constructing clusters of daughter grains (room-temperature hcp α-phase) that have a high probability of being transformed from the same parent grain (high-temperature bcc β-phase). These clusters are then grown, and back-transformed to the parent grain orientations using the ‘summation of mutual misorientation angle method’ (SMMA method). The cluster method is validated by comparing the obtained results with the results of the SMMA and triplet methods.     

High temperature mechanics of nanomoulded amorphous metals

High temperature mechanics of nanomoulded amorphous metals was investigated by in situ nanomechanical testing. Nanopillars of Pd₄₃Cu₂₇Ni₁₀P₂₀ metallic glass were synthesized by thermoplastic forming and their stress–strain response was obtained concurrent with direct observation of their deformation behaviour. This allowed the measurement of mechanical behaviour from nanopillars and the corresponding bulk substrate with identical thermal history. A rise in elastic modulus was seen with increase in temperature for both the nanopillars and substrate, which was explained by diffusive rearrangement of atomic-scale viscoelastic units. The results provide fundamental insights into structural rearrangement in metallic glasses.     

Ethnic Speech and Ethnic Action as Ethnic Behavior: Part 2. Validation of the Brunel Ethnic Behavior Inventory

This study sought to validate the Brunel Ethnic Behavior Inventory (BEBI) as a measure of two aspects of “doing” (i.e., ethnic speech and ethnic action) among the “ways of ethnicity” identified by Verkuyten. It also evaluates the construct validity of the BEBI alongside the Multigroup Ethnic Identity Measure-Revised (MEIM-R) and evaluates the BEBI and the MEIM-R (the latter of which measures exploration as “thinking” and commitment as “feeling” among ways of ethnicity) regarding criterion-related validity. Across two samples (n = 120 for Sample 1 and n = 148 for Sample 2), the BEBI and the MEIM-R performed suitably with regard to construct validity. However, the BEBI arguably performed better with regard to criterion-related validity (i.e., in predicting scores on life satisfaction, flourishing, positive and negative moods, and positive and negative emotions). Implications for validation studies on ways of ethnicity are discussed.

Traumatic Incidents and Experiences of Racism and Sexism: Examining Associations with Components of Critical Consciousness for System‐Involved Girls of Color

Scholarship identifies critical consciousness as a key developmental asset in promoting the well‐being of adolescents experiencing multiple socio‐structural axes of oppression. Girls of color at acute risk for legal system involvement or re‐involvement are absent from this literature. They are a critical population in which to examine this construct given their experiences of oppression and the myriad benefits of critical consciousness. The current study addresses this gap by examining traumatic incidents and experiences of racism and sexism as correlates of critical reflection and action among a sample of girls (N = 220; Mean age = 14.5 years; SD = 1.3 years). Using path analysis and multigroup modeling, we examine direct associations between these three manifestations of structural oppression and critical consciousness and explore the interplay of traumatic incidents, and racism and sexism in girls’ critical consciousness development. Findings suggest that experiences of sexism and racism, uniquely and positively predict critical action, but not critical reflection. Surprisingly, girls’ experiences of traumatic incidents do not predict reflection or action. Finally, multigroup analyses show no evidence that these associations vary by the interplay of traumatic incidents, racism, and sexism. Implications for community psychology values and juvenile legal system practice and policy are discussed.     

Ranking of Drivers for Green Manufacturing Implementation Using Fuzzy Technique for Order of Preference by Similarity to Ideal Solution Method

The governments are under tremendous pressure to sustain high manufacturing growth in emerging economies. Unfortunately, the manufacturing sector consumes much energy and other resources and emits a large amount of green house gases, which increases environmental problems such as climate change and global warming. One possible solution to this problem is green manufacturing (GM) implementation in industry. However, GM implementation faces many challenges. Various motivating factors named as ‘drivers’ should be facilitated by the government and industry to make this change possible. This paper investigates the drivers for GM implementation and their ranking based on fuzzy technique for order of preference by similarity to ideal solution method using government, industry and experts perspectives. The study concluded that competitiveness, incentives, organizational resources and technology are top ranked drivers and should be facilitated by the government and industry to help implement GM. The ranking of these drivers is expected to help the government and industry to focus on few important drivers to facilitate the GM implementation with limited resources.

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.     

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.
