Drastic variation in the surface boundary layer parameters over Cochin during the annular solar eclipse: Analysis using sonic anemometer data

Atmospheric surface boundary layer parameters vary anomalously in response to the occurrence of annular solar eclipse on 15th January 2010 over Cochin. It was the longest annular solar eclipse occurred over South India with high intensity. As it occurred during the noon hours, it is considered to be much more significant because of its effects in all the regions of atmosphere including ionosphere. Since the insolation is the main driving factor responsible for the anomalous changes occurred in the surface layer due to annular solar eclipse, occurred on 15th January 2010, that played very important role in understanding dynamics of the atmosphere during the eclipse period because of its coincidence with the noon time. The Sonic anemometer is able to give data of zonal, meridional and vertical wind as well as the air temperature at a temporal resolution of 1 s. Different surface boundary layer parameters and turbulent fluxes were computed by the application of eddy correlation technique using the high resolution station data. The surface boundary layer parameters that are computed using the sonic anemometer data during the period are momentum flux, sensible heat flux, turbulent kinetic energy, frictional velocity (u*), variance of temperature, variances of u, v and w wind. In order to compare the results, a control run has been done using the data of previous day as well as next day. It is noted that over the specified time period of annular solar eclipse, all the above stated surface boundary layer parameters vary anomalously when compared with the control run. From the observations we could note that momentum flux was 0.1 Nm 2 instead of the mean value 0.2 Nm-2 when there was eclipse. Sensible heat flux anomalously decreases to 50 Nm 2 instead of the mean value 200 Nm 2 at the time of solar eclipse. The turbulent kinetic energy decreases to 0.2 m2s 2 from the mean value 1 m2s 2. The frictional velocity value decreases to 0.05 ms 1 instead of the mean value 0.2 ms 1. The present study aimed at understanding the dynamics of surface layer in response to the annular solar eclipse over a tropical coastal station, occurred during the noon hours. Key words: annular solar eclipse, surface boundary layer, sonic anemometer

Impact of Quality on Ethics and Social Responsibility in Marketing, in Industries in Kerala in the present Indian Scenario

The paper ‘Impact of Quality on Ethics and Social Responsibility in Marketing in Industries in Kerala in the present Indian scenario’ highlights the observations, based on a descriptive research carried out in five leading industries in Kerala, in the private and public sector. Ethics and social responsibilities, practiced in these industries, are reflected in the results of the survey conducted on specific queries like awareness of products/services provided by them, total understanding of the requirements of the customer, open discussion on technical matters, accountability of employees to the society and social needs, consumer ethics vis a vis business ethics etc. Team working goes a long way, in building relations, which in turn, results in a progressive and effective marketing strategy. This assumes paramount importance, considering the severe competition we are facing in the light of liberalization, privatization and globalization, which encompasses the globe. The prediction of India becoming a lead nation, along with USA, China and Japan, in this decade, can get fructified only if we follow a very high standards of ethics and social responsibility, in all domains including marketing. Organizations like TRW.Rane, Sundaram Fasteners, TVS Motors, in Chennai are a few among others in India, who have achieved the highest distinction in quality viz Deming Prize, and these demonstrate their commitment to quality, society and humanity at large. Cost effectiveness, without jeopardizing quality has become the need of the hour and MRTP has become history. This trait is being brought out through the survey and the results speak for themselves. Unethical practices like switch and bait, not only brings shame to the organization, and country but also results in the company getting wiped out from the market. Adherence to standards like ISO 14000 helps to maintain the minimum level of social responsibility and environmental friendliness. Like quality audit, safety audit etc, social audit is being insisted in all progressive countries to ensure that the organization comply with the minimum statutory requirements. The paper also touches upon Corporate Social Responsibility practiced in the industries and this becomes crystal clear through their commitment to improve the community. Green Marketing lays a lot of importance on the three Rs of environmentalism viz Reduce, Reuse and Recycle. The objective of any business is to achieve optimal profit and this is possible only by reducing the cost as well as waste. In this context, management tools like brainstorming, suggestion schemes, benchmarking etc becomes helpful. These characteristics are brought out through the analysis of survey results. The conclusions drawn throw a lot of information on the desirable practices with respect to Ethics and Social Responsibility in Marketing

Addressing endogeneity in the relationship between health and employment through a simultaneous equations model

Este documento analiza la relación de doble causalidad entre salud y empleo y su comportamiento dinámico usando datos de Estados Unidos tomados del PSID (Pane Study of Income Dynamics). Este estudio usa dos variables dependientes (Estado de salud auto-reportado y Empleo), las cuales son estimadas usando un modelo probit bivariado para abordar el problema de endegeneidad presente en dicha relación. Los resultados muestran evidencia significativa de la existencia de dicha endogeneidad y del impacto positivo que tiene sobre la probabilidad de ser empleado tener un buen estado de salud y vicesersa, sin embargo, el impacto de la situación de empleo sobre el estado de salud se encuentra que no es significativa.

Brief neuropsychological assessment of adults post-stroke in the left hemisphere

The neuropsychological assessment investigates cognitive deficits to improve the diagnosis, the prognosis and the rehabilitation of patients. In Brazil, stroke is a major cause of hospitalization and the leading cause of mortality and disability. The stroke in the left hemisphere (LH) is associated with different degrees of loss of language and other cognitive impairments, for example, in the memory. We compared the performance in brief neuropsychological tasks of the left hemisphere poststroke patients, without moderate or severe aphasia, with healthy controls. A list of 135 patients was selected based on inclusion criteria. The study included 15 patients with left stroke, paired by sex, age and education to 30 neurologically healthy adults. The data resulting from application of the Neupsilin Brief Neuropsychological Assessment Instrument were analyzed with the nonparametric Mann-Whitney U. Adults with LH stroke showed a significant reduction in performance when compared to healthy controls on language, working memory and ideomotor praxis, results also found in other studies of patients with left hemisphere stroke

Predictors of Attitudes toward Cosmetic Surgery among U.S. and Colombian College Women: The Roles of Eating Behaviors and Demographic Variables

Cross-cultural studies on eating behaviors and related constructs can identify cultural and social factors that contribute to eating disorder symptomatology. Eating disorders (EDs) are a major cause for concern in the U.S., and recent studies in Colombia have shown growing rates among their female population. In addition, cosmetic surgery procedures have been increasing rapidly in both the U.S. and Colombia, and preliminary research suggests a positive relation between disordered eating and endorsement of plastic surgery. In samples of college women from Colombia and the U.S., we investigated patterns of association between disordered eating variables and cosmetic surgery acceptance. Our approach utilized separate analyses for various subcomponents of disordered eating (to determine their unique associations with cosmetic surgery acceptance) while adjusting for potentially relevant covariates and examining cross-cultural patterns. Participants were students at an urban, public college in the U.S. (n=163) and an urban, private college in Colombia (n=179). Overall, our findings suggested that participants from Colombia with greater disordered eating were more likely to endorse cosmetic surgery for social reasons, while those from the U.S. were more likely to consider undergoing cosmetic surgery for personal reasons. Differing findings between the two samples may be due to cultural and social factors, which we delineate. These findings also have potential implications for presurgical counseling of cosmetic surgery candidates.

Market access in the western hemisphere: implications for the Andean Community

Este estudio busca contribuir a la evaluación del impacto económico que una mayor liberalización comercial en el Hemisferio Occidental, puede tener sobre los países miembros de la Comunidad Andina. Los escenarios de liberalización comercial más significativos se identifican y simulan, mediante el uso del modelo GTAP en su versión estándar de rendimientos constantes a escala. Los resultados básicos indican una muy baja coincidencia en la dirección de los cambios de bienestar esperables para los países andinos, bajo los cuatro escenarios analizados. De una forma muy simplificada, puede decirse que una mayor liberalización comercial implica pérdidas de bienestar para Colombia, Perú y Ecuador-Bolivia, en tanto que para Venezuela se encuentran ganancias bajo los escenarios que implementan el Área de Libre Comercio de las Américas y pérdidas bajo el que implementa el Acuerdo de Libre Comercio entre sus socios andinos y Estados Unidos. Los términos de intercambio juegan un papel determinante en estos resultados. En general se mueven en contra de estas economías, con la notoria excepción de Venezuela. Al parecer, los países andinos se han beneficiado en el pasado de la desviación de comercio que otras regiones han sufrido, como consecuencia de los acuerdos preferenciales de comercio en los cuales los primeros han participado. Con la erosión del acceso preferencial a otros mercados, implícita en los escenarios simulados, el aumento en la competencia tanto por el lado de las exportaciones como por el de las importaciones, tiende a ajustar la posición internacional de estos países, trayendo con ello nuevos retos para el manejo de sus economías.
