Independent and mediating organizational commitment effects of trust in leadership on employees' job satisfaction and : a study within social and health care sector

The purpose of this study was to examine whether trust in supervisor and trust in senior management enhance employees' job satisfaction and organizational commitment, and whether trust mediates the relationship between perceived justice and these outcomes. Trust in supervisor was expected to mediate the effects of distributive justice and interactional justice, and trust in senior management was expected to mediate the effects of procedural justice. Theoretical background of the study is based on the framework for trust in leadership developed by Dirks and Ferrin (2002). According to the framework, perceived fairness of leaders' actions helps employees to draw inferences about the basis of the relationship and about leaders' characters. This allows trust formation. Reciprocation of care and concern in the relationship and confidence in leaders' characters are likely to enhance employees' job satisfaction and organizational commitment. This study was conducted with cross-sectional data (A/ = 960) of employees from social and health care sector. Hypotheses were studied using correlation analysis and several hierarchical regression analyses. Significances of the mediations were assessed using the Sobel test. Results partially supported the hypotheses. Trust in leadership was positively related to job satisfaction and organizational commitment. Trust in senior management mediated the relationship between procedural justice and the outcomes. Some support was also found for the mediating effect of trust in supervisor in the relationship between distributive justice and organizational commitment. Due to high correlation between trust in supervisor anil interactional justice, it wasn't possible to study the mediating e fleet of trust in supervisor in the relationship between interactional justice and the outcomes. Against expectations, results indicated that trust in senior management had a mediating effect in the relationship between distributive justice and organizational commitment, and in the relationship between interactional justice and organizational commitment. Results also indicated that trust in supervisor had a mediating effect in the relationship between procedural justice and organizational commitment.

Differential cellular recognition pattern to M. tuberculosis targets defined by IFN-gamma and IL-17 production in blood from TB plus patients from Honduras as compared to health care workers: TB and immune responses in patients from Honduras

Background: A better understanding of the quality of cellular immune responses directed against molecularly defined targets will guide the development of TB diagnostics and identification of molecularly defined, clinically relevant M.tb vaccine candidates. Methods: Recombinant proteins (n = 8) and peptide pools (n = 14) from M. tuberculosis (M.tb) targets were used to compare cellular immune responses defined by IFN-gamma and IL-17 production using a Whole Blood Assay (WBA) in a cohort of 148 individuals, i.e. patients with TB + (n = 38), TB- individuals with other pulmonary diseases (n = 81) and individuals exposed to TB without evidence of clinical TB (health care workers, n = 29). Results: M.tb antigens Rv2958c (glycosyltransferase), Rv2962c (mycolyltransferase), Rv1886c (Ag85B), Rv3804c (Ag85A), and the PPE family member Rv3347c were frequently recognized, defined by IFN-gamma production, in blood from healthy individuals exposed to M.tb (health care workers). A different recognition pattern was found for IL-17 production in blood from M.tb exposed individuals responding to TB10.4 (Rv0288), Ag85B (Rv1886c) and the PPE family members Rv0978c and Rv1917c. Conclusions: The pattern of immune target recognition is different in regard to IFN-gamma and IL-17 production to defined molecular M.tb targets in PBMCs from individuals frequently exposed to M.tb. The data represent the first mapping of cellular immune responses against M.tb targets in TB patients from Honduras.

Mud-packing frog: A novel breeding behaviour and parental care in a stream dwelling new species of Nyctibatrachus (Amphibia, Anura, Nyctibatrachidae)

Reproductive modes are diverse and unique in anurans. Selective pressures of evolution, ecology and environment are attributed to such diverse reproductive modes. Globally forty different reproductive modes in anurans have been described to date. The genus Nyctibatrachus has been recently revised and belongs to an ancient lineage of frog families in the Western Ghats of India. Species of this genus are known to exhibit mountain associated clade endemism and novel breeding behaviours. The purpose of this study is to present unique reproductive behaviour, oviposition and parental care in a new species Nyctibatrachus kumbara sp. nov. which is described in the paper. Nyctibatrachus kumbara sp. nov. is a medium sized stream dwelling frog. It is distinct from the congeners based on a suite of morphological characters and substantially divergent in DNA sequences of the mitochondrial 16S rRNA gene. Males exhibit parental care by mud packing the egg clutch. Such parental care has so far not been described from any other frog species worldwide. Besides this, we emphasize that three co-occurring congeneric species of Nyctibatrachus, namely N. jog, N. kempholeyensis and Nyctibatrachus kumbara sp. nov. from the study site differ in breeding behaviour, which could represent a case of reproductive character displacement. These three species are distinct in their size, call pattern, reproductive behaviour, maximum number of eggs in a clutch, oviposition and parental care, which was evident from the statistical analysis. The study throws light on the reproductive behaviour of Nyctibatrachus kumbara sp. nov. and associated species to understand the evolution and adaptation of reproductive modes of anurans in general, and Nyctibatrachus in particular from the Western Ghats.

Cuidados paliativos y magisterio de la Iglesia

Resumen: Para entender el Cuidado Paliativo, según el Personalismo ontológico y el Magisterio, se necesita una ética del cuidado, basado en el imperativo del amor al prójimo. El centro de toda la asistencia es la persona, el respeto por su dignidad y la inviolabilidad de la vida humana, sin dejar de hacer referencia al fin último trascendente que fundamenta toda la existencia. Se considera imprescindible el diálogo integrador entre la fe, la razón y las ciencias que permita iluminar los Cuidados Paliativos a través de una antropología y filosofía moral que guíe la praxis de los profesionales y voluntarios. En el Hospice Madre Teresa se cuida al enfermo hasta su fin natural intentando anunciar el Se ayuda a todas las personas a descubrir, a la luz de la razón y de la fe, el significado a su existencia. Se trata de encontrar puntos de diálogo con los no creyentes para promover la cultura de la vida sabiendo que la razón, iluminada por la fe, se libera de los límites propios de la naturaleza humana encontrando la fuerza necesaria para elevarse al conocimiento del misterio de Dios.

Una mirada universitaria sobre la anencefalia

Resumen: Un niño con anencefalia, debido a su innegable condición humana, merece ser tratado con respeto y dignidad, como cualquier otro hombre. Por su severa patología y su corta expectativa de vida, es una criatura frágil e indefensa a la que hay que cuidar, y no por ello aplicar tratamiento, hasta que devenga su inevitable muerte. La futilidad de cualquier medida agresiva sustenta la necesidad de proporcionarle calor y cuidados básicos, sin incurrir en tratamientos desproporcionados. Al mismo tiempo, resulta fundamental informar, acompañar y brindar apoyo médico y psicológico a toda la familia, en especial a la madre, para poder superar la muerte del niño. Por último, es preciso establecer que el pronóstico ominoso de una criatura anencefálica jamás justifica el aborto. A partir del estudio de la bibliografía argentina sobre el tema, y desde la perspectiva de un estudiante de medicina, se analizan los textos publicados, añadiendo algunos comentarios éticos actuales sobre los problemas de la anencefalia.
