An empirical analysis of the impact of various dimensions of work-life balance on organizational commitment among service sector employees in India

The present study examined the relationships of the various facets of work-family balance with organisational commitment (OC) and its various dimensions among employees working in the service sector in India. Data were collected from 408 employees by means of questionnaires. Correlation and linear regression analysis of the collected data demonstrated that while one of the dimensions of work-life balance namely, work interferes with personal life (WIPL), acted as a significant negative predictor of OC, another dimension that is work enhancement/ personal enhancement (WE/PE) showed significant positive impact on OC. The third dimension, personal life interferes with work (PLIW) even though showed a negative correlation; the impact was generally not significant. The article concludes with the managerial implications of the study in service sector industries/institutions

Implicit self-consistent electrolyte model in plane-wave density-functional theory

The ab-initio computational treatment of electrochemical systems requires an appropriate treatment of the solid/liquid interfaces. A fully quantum mechanical treatment of the interface is computationally demanding due to the large number of degrees of freedom involved. In this work, we describe a computationally efficient model where the electrode part of the interface is described at the density-functional theory (DFT) level, and the electrolyte part is represented through an implicit solvation model based on the Poisson-Boltzmann equation. We describe the implementation of the linearized Poisson-Boltzmann equation into the Vienna Ab-initio Simulation Package (VASP), a widely used DFT code, followed by validation and benchmarking of the method. To demonstrate the utility of the implicit electrolyte model, we apply it to study the surface energy of Cu crystal facets in an aqueous electrolyte as a function of applied electric potential. We show that the applied potential enables the control of the shape of nanocrystals from an octahedral to a truncated octahedral morphology with increasing potential

Use of vancomycin in the culture of Mycobacterium tuberculosis from gastric lavage

Background & objectives: Earlier studies from the Tuberculosis Research Centre, Chennai, on culture of Mymbocterium (tuberculosis from gastric lavage (GL) specimens in selective Kirchner's medium (SK) resulted in a loss of 60 per cent culture results due to contamination with aerobic spore bearers (ASB). Addition of vancomycin to SK (SKV) effectively reduced the contamination rate to 20 per cent. The objective of the present study was to further reduce the contamination by collecting the specimens in bottles containing vancomycin, thus providing continuous exposure of the sample to the drug, which is bactericidal to ASB. Methods: One thousand GL specimens coIIected from children in vancomycin containing bottles were decontaminated and cultured in SK medium, with and without vancomycin, subcultured on Lowenstein Jensen (W) medium and the culture results compared. Results: The contamination of cultures in SK and SKV was 15 and 4 per cent respectively when the specimens were collected in bottles containing vancomycin compared to 60 and 20 per cent contamination reported in the earlier studies. interpretation & conclusion: The reduced contamination in SK and SKV is most likely due to the collection of sample in vancomycin containing bottles. Although a concurrent comparison of samples processed in vancomycin free conditions would have been ideal, it could not be done due to practical difficulties. The study thus confirms the value of vancomycin as a major deterrent for contamination due to aerobic spores and better results can be obtained if vancomycin is used in sample collection bottles, transport media and liquid culture media used in mycobacteriology laboratories particularly in humid and tropical environment

A Bibliographic Essay on Hindu and Christian Dalit Religiosity

In his now classic novel Untouchable, Mulk Raj Anand portrays the life of a sweeper named Bakha. Bakha works cleaning latrines at the Cantonment, imitates the British tommies in his attire, and negotiates the differing spaces in which is Untouchability is defined. After an incident during which Bakha inadvertently touches a caste Hindu in the street, Bakha wanders through town. During his wanderings, he first meets a Christian missionary who speaks almost incomprehensibly about Jesus. Bakha then listens to a speech by Mahatma Gandhi and while he finds the Mahatma\u27s vision compelling, his mind turns to reflecting upon how flush toilets might be the real answer to his plight. As Anand portrays him, Bakha the sweeper is neither Hindu nor can he somehow become a Christian, for as an Untouchable he remains trapped in a wholly other spacial domain

A comparison of measured and simulated solar network contrast

Long-term trends in the solar spectral irradiance are important to determine the impact on Earth's climate. These long-term changes are thought to be caused mainly by changes in the surface area covered by small-scale magnetic elements. The direct measurement of the contrast to determine the impact of these small-scale magnetic elements is, however, limited to a few wavelengths, and is, even for space instruments, affected by scattered light and instrument defocus. In this work we calculate emergent intensities from 3-D simulations of solar magneto-convection and validate the outcome by comparing with observations from Hinode/SOT. In this manner we aim to construct the contrast at wavelengths ranging from the NUV to the FIR.Comment: Proceedings paper, IAU XXVII, Symposium 264, 3 page

Coronal mass ejections and magnetic flux buildup in the heliosphere

To test for magnetic flux buildup in the heliosphere from coronal mass ejections (CMEs), we simulate heliospheric flux as a constant background open flux with a time-varying interplanetary CME (ICME) contribution. As flux carried by ejecta can only contribute to the heliospheric flux budget while it remains closed, the ICME flux opening rate is an important factor. Two separate forms for the ICME flux opening rate are considered: (1) constant and (2) exponentially decaying with time. Coronagraph observations are used to determine the CME occurrence rates, while in situ observations are used to estimate the magnetic flux content of a typical ICME. Both static equilibrium and dynamic simulations, using the constant and exponential ICME flux opening models, require flux opening timescales of ∼50 days in order to match the observed doubling in the magnetic field intensity at 1 AU over the solar cycle. Such timescales are equivalent to a change in the ICME closed flux of only ∼7–12% between 1 and 5 AU, consistent with CSE signatures; no flux buildup results. The dynamic simulation yields a solar cycle flux variation with high variability that matches the overall variability of the observed magnetic field intensity remarkably well, including the double peak forming the Gnevyshev gap
