Exploring Dimensions of Teachers’ OCB from Stakeholder’s Perspective: A Study in India

Parents are real beneficiaries of school services. Their involvement in school based activities has changed the role breadth of teachers. Schools can handle this parental involvement through the extra-role behaviors of teachers. These beyond the job behaviors or organizational citizenship behaviors (OCB) of teachers are crucial for the schools. Despite the prescribed roles and duties, the schools cannot predict and infer through formally stated in-role job description, the entire range of extra-role behavior exhibited by teachers during and after school. In this study, teacher’s role breadth is examined under the broad spectrum of Organizational Citizenship Behavior (OCB) which resulted into a conceptual model on the determinants of teacher’s OCB. A qualitative evaluation (grounded theory) of 40 interviews has been conducted with all the stakeholders of school in India viz., principals, fellow-teachers, students, and parents. The most striking finding is that teachers are displaying prosocial behavior. Teacher’s OCB is found to have three determinants—OCB-Individual, OCB-Organization and OCB-Prosocial. Involvement of parents in school are redesigning and affecting the actions of teacher. Further, the implications and directions for future research have also been discussed

On the role of different Skyrme forces and surface corrections in exotic cluster-decay

We present cluster decay studies of $^{56}$Ni$^*$ formed in heavy-ion collisions using different Skyrme forces. Our study reveals that different Skyrme forces do not alter the transfer structure of fractional yields significantly. The cluster decay half-lives of different clusters lies within \pm 10% for PCM and \pm 15% for UFM.Comment: 13 pages,6 figures and 1 table; in press Pramana Journal of Physics (2010

Mexico City and the biogeochemistry of global urbanization

Mexico City is far advanced in its urban evolution, and cities in currently developing nations may soon follow a similar course. This paper investigates the strengths and weaknesses of infrastructures for the emerging megacities. The major driving force for infrastructure change in Mexico City is concern over air quality. Air chemistry data from recent field campaigns have been used to calculate fluxes in the atmosphere of the Valley of Mexico, for compounds that are important to biogeochemistry including methane (CH4), carbon monoxide (CO), nonmethane hydrocarbons (NMHCs), ammonia (NH3), sulfur dioxide (SO2), nitrogen oxides (NOx and NOy), soot, and dust. Leakage of liquified petroleum gas approached 10% during sampling periods, and automotive pollutant sources in Mexico City were found to match those in developed cities, despite a lower vehicle-to-person ratio of 0.1. Ammonia is released primarily from residential areas, at levels sufficient to titrate pollutant acids into particles across the entire basin. Enhancements of reduced nitrogen and hydrocarbons in the vapor phase skew the distribution of NOy species towards lower average deposition velocities. Partly as a result, downwind nutrient deposition occurs on a similar scale as nitrogen fixation across Central America, and augments marine nitrate upwelling. Dust suspension from unpaved roads and from the bed of Lake Texcoco was found to be comparable to that occurring on the periphery of the Sahara, Arabian, and Gobi deserts. In addition, sodium chloride (NaCl) in the dust may support heterogeneous chlorine oxide (ClOx) chemistry. The insights from our Mexico City analysis have been tentatively applied to the upcoming urbanization of Asia
