    Description: The electrode characteristics and selectivities of PVC-based thiocyanate selective polymeric membrane electrode (PME) incorporating the newly synthesized zinc complex of 6,7:14,15-Bzo(2)-10,11-(4-methylbenzene)-[15]-6,8,12,14-tetraene-9,12-N(2)-1,5-O(2) (I(1)) and zinc complex of 6,7:14,15-Bzo(2)-10,11-(4-methylbenzene)-[15]-6,14-diene-9,12-dimethylacrylate-9,12-N(2)-1,5-O(2) (I(2)) are reported here. The best response was observed with the membrane having a composition of I(2):PVC:o-NPOE:HTAB in the ratio of 6:33:59:2 (w/w; milligram). This electrode exhibited Nernstian slope for thiocyanate ions over working concentration range of 4.4 × 10(-7) to 1.0 × 10(-2) mol L(-1) with detection limit of 2.2 × 10(-7) mol L(-1). The performance of this electrode was compared with coated graphite electrode (CGE), which showed better response characteristics w.r.t Nernstian slope 59.0 ± 0.2 mV decade(-1) activity, wide concentration range of 8.9 × 10(-8) to 1.0 × 10(-2) mol L(-1) and detection limit of 6.7 × 10(-8) mol L(-1). The response time for CGE and PME was found to be 8 and 10 s, respectively. The proposed electrode (CGE) was successfully applied to direct determination of thiocyanate in biological and environmental samples and also as indicator electrode in potentiometric titration of SCN(-) ion.

    Description: A novel concept of self-repairable glass useful as seals in solid oxide fuel cells (SOFCs) is proposed, developed, and used for making metal-glass–ceramic seals for enhancing reliability and life. In this concept, cracks created during SOFC operation are repaired by the crack healing process driven by the viscous flow of the glass. An approach for studying the kinetics of crack healing in glasses responsible for the self-repair is described and used to study the crack healing behavior. The cracks are created by a microindenter, and the progression of healing of cracks thus created on a silicate glass surface is experimentally determined at different annealing temperatures and times. Sequential changes in the crack morphology during thermal healing are also studied to identify the three stages of crack healing process. A crack healing model, based on the relationship among crack length, time, temperature, glass viscosity, and its flow behavior is developed in order to describe and predict the time required for self-repair on a glass surface. The predictions from the developed model is then compared with the experimental data and found to be in good agreement. These results also demonstrated the relative importance of the different stages of crack healing on the overall healing or self-repair behavior.

    Description: Evolutionary and feminist perspectives on female beauty are compatible in some respects, such as the oppressive and destructive outcomes for women as a consequence of the importance attached to female beauty. The perspectives tend to differ on the issue of the origins of (some) beauty standards. Evolutionary scientists have proposed that beauty is a reliable cue for women’s health and fertility. However, as the factors regulating health and reproductive capabilities cannot be directly observed, sexual selection has fashioned psychological adaptations to attend to bodily features that are correlated with health and fertility. It is proposed that people resonate to such bodily features and find them attractive. One such bodily feature in women is gynoid body distribution (i.e., female-normative body shape in which fat distribution is concentrated around hips and thighs). Gynoid body fat distribution is measured by the ratio of waist and hips circumferences (WHR). In this paper we summarize empirical evidence showing that WHR is an independent predictor for risks for major diseases, optimal hormonal profile, and reproductive capabilities. Next, we present findings from studies that demonstrate systematic variations in the size of WHR produce systematic changes in judgment of female attractiveness within diverse societies throughout the world. Such widespread appeal of low WHR suggests that people have evolved mental mechanisms to judge body features indicative of good health as attractive, meaning that some standards of beauty are not arbitrary or constructed. We conclude that a better understanding and appreciation of the beauty-health linkage can be empowering to women.

    Description: An elderly male with metastatic pancreatic adenocarcinoma and no prior history of pedal edema presented with painful, confluent, macular erythema on bilateral lower extremities with grade III lower extremity edema for 1 week following two cycles of gemcitabine. He was afebrile with local warmth and tenderness and a total leukocyte count of 5000 cells/mm3. An initial diagnosis of cellulitis was made after a negative Doppler ultrasound for DVT was completed. The patient was started on cefazolin. However, failure of the antibiotic trial and absent systemic manifestations led to the presumptive diagnosis of gemcitabine associated pseudocellulitis. The symptoms promptly resolved with withdrawal of the offending agent (Fig. 1).

    Description: To investigate the relationship between pregnancy intendedness and utilization of recommended prenatal care for mothers and vaccinations for children against six vaccine preventable diseases in rural India using a prospective dataset. To examine the association between pregnancy intention and neonatal and infant mortality in rural India. The study is based upon a prospective follow-up survey of a cohort selected from the National Family Health Survey 1998–1999, carried out in 2002–2003 in rural areas of four Indian states of Bihar, Jharkhand, Maharashtra and Tamil Nadu. Data for 2108 births for which pregnancy intendedness was assessed prospectively was analyzed using bivariate analysis, logistic regressions and discrete-time survival analysis. Mothers reporting unwanted births were 2.32 (95 % CI: 1.54–3.48) times as likely as mothers reporting wanted births to receive inadequate prenatal care. Moreover, unwanted births were 1.38 (95 % CI: 1.01–1.87) times as likely as wanted births to receive inadequate childhood vaccinations. Likewise, births that were identified as mistimed/unwanted had 83 % higher risk of neonatal mortality compared to wanted births. The association between pregnancy intendedness and infant mortality was only marginally significant. This is the first study of its kind which has investigated the relationship between prospectively assessed pregnancy intendedness and early childhood mortality in rural India. The study provides additional and more conclusive evidence that unwanted births are disadvantaged in terms of maternal and child health outcomes. Findings argue for enhanced focus on family planning to reduce the high prevalence of unintended pregnancy in rural India.

    Description: An important aspect of brand perception emanates from its corporate social responsibility (CSR) activity. When two brands involved in CSR activities form a cobranding alliance, their respective CSR perceptions can impact consumer attitudes toward the alliance. As an ethically-oriented strategy, the alliance can be potentially beneficial to both partner brands, and can create opportunities for promoting CSR activities. The research streams on brand management, cobranding, and CSR, however, are silent about this important branding strategy that has several embedded business and societal benefits. This study examines how CSR-based consumer perceptions and ethical self-identity impact consumer evaluation of cobrands. Employing a quasi-experimental between-subjects design, the study tests six cobranding scenarios in three product categories. The data were collected via structured questionnaires resulting in 318 valid responses. The data were analyzed employing Partial Least Squares Structural Equation Modeling. The results confirm that positive CSR perceptions toward the partner brands are robust indicators of attitudes toward cobrands. Further, the match between the CSR activities of the partner brands (positive CSR fit) and the product categories (product fit) influences cobrand attitudes. The results also show evidence of ‘spill-over’ effects, where the alliance has a positive impact on subsequent CSR perceptions toward the partner brands. Additionally, the findings demonstrate an asymmetry in the effects of the cobrand on subsequent CSR perceptions wherein consumers with low ethical self-identity show greater spill-over effects from the cobrand than those with high ethical self-identity. The study contributes to knowledge in the domains of business ethics, cobranding, and social responsibility. The findings have managerial implications for designing CSR-based ethical branding strategies for cobrands.

    Description: In this article, we develop theoretical and empirical linkages between corporate social responsibility (CSR) initiatives of business organizations and their market development efforts at the bottom of the pyramid (BOP). We use qualitative in-depth interviews of 21 CSR heads of business organizations and its CSR partner organizations in India (an emerging market) to explore, develop, and explain plausible theoretical linkages between CSR initiatives of the organizations and its market development efforts at BOP using theory of market separations. Using theoretical frameworks from CSR literature and sub-theory of market separations from marketing literature, the study suggests that market development at BOP is enhanced using the CSR route in several ways. These are, (1) making the BOP market development less risky, (2) mask the CSR initiative as a BOP pilot project to generate internal traction within the organization, (3) integrating the BOP communities with the last mile of the supply chain of the organization, (4) bringing government intervention to accelerate scale-up, and (5) developing BOP as future markets for consumers and supply chain partners to make business more sustainable. Our study has several theoretical as well as managerial implications linking organizations’ market development efforts at BOP with its CSR initiatives.

    Description: 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.

    Description: Rationale Cannabinoid [CB.sub.1] receptor agonists vary in efficacy in vitro; however, relationships between efficacy and behavioral effects are unclear. Objective This study examined the relationship between apparent [CB.sub.1] agonist efficacy and in vivo effects. Methods Male C57BL/6J mice responded for food under a fixed ratio 30 schedule; rectal temperature was measured. Sensitivity of the mice to cannabinoid agonists (rank order efficacy in vitro reported to be CP 55940 〉 anandamide 〉 [[DELTA].sup.9]- tetrahydrocannabinol; [[DELTA].sup.9]-THC) and a non-cannabinoid (the benzodiazepine midazolam) was determined before, during, and after discontinuation of daily [[DELTA].sup.9]-THC treatment (32 mg/kg/day, i.p.). Rimonabant was combined with cannabinoids to examine whether [CB.sub.1] receptors mediated effects on response rate. Results [[DELTA].sup.9]-THC, CP 55940, anandamide, and midazolam decreased responding at doses smaller than those producing hypothermia. Rimonabant antagonized the rate-decreasing effects of [[DELTA].sup.9]-THC and CP 55940, but not those of anandamide. [[DELTA].sup.9]-THC treatment produced tolerance for both rate-decreasing and hypothermic effects. [DELTA].sup.9]-THC treatment did not change sensitivity to the rate-decreasing effects of CP 55940, but produced cross-tolerance to CP 55940 for hypothermic effects. [[DELTA].sup.9]-THC treatment did not modify sensitivity to anandamide and midazolam. Conclusions [CB.sub.1] receptors mediate the operant rate decreasing effects of [[DELTA].sup.9]-THC and CP 55940, but not anandamide, in mice. [CB.sub.1] agonist efficacy is an important determinant of in vivo effects, especially with regard to the magnitude of tolerance and cross-tolerance resulting from daily [[DELTA].sup.9]-THC treatment. This applies not only to different cannabinoids when measuring the same effect but also to the same cannabinoid when measuring different effects.
