Numerous low - pressure systems form in the Arabian Sea and Bay of Bengal. These low-pressure systems are highly useful in bringing the rainfall over the Indian sub continent. The developments of these systems are accompanied by the reduction in air temperature and an increase in atmospheric humidity. The radio refractivity, which is a function of the atmospheric pressure, temperature and humidity, also changes following the development of these systems. Variation of radio refractive index and its vertical gradient are analysed for many low pressure systems formed over the Arabian Sea and Bay of Bengal. It is found that the atmosphere becomes super refractive associated with the formation of these systems, caused by the increase in humidity and decrease in temperature. The maximum gradient is observed near the surface layers, especially in the lowest 1 km. Super refraction leads to increased radar detection range and extension of radio horizon

The Paper unfolds the paradox that exists in the tribal community with respect to the development indicators and hence tries to cull out the difference in the standard of living of the tribes in a dichotomous framework, forward and backward. Four variables have been considered for ascertaining the standard of living and socio-economic conditions of the tribes. The data for the study is obtained from a primary survey in the three tribal predominant districts of Wayanad, Idukki and Palakkad. Wayanad was selected for studying six tribal communities (Paniya, Adiya, Kuruma, Kurichya, Urali and Kattunaika), Idukki for two communities (Malayarayan and Muthuvan) and Palakkad for one community (Irula). 500 samples from 9 prominent tribal communities of Kerala have been collected according to multistage proportionate random sample framework. The analysis highlights the disproportionate nature of socio-economic indicators within the tribes in Kerala owing to the failure of governmental schemes and assistances meant for their empowerment. The socio-economic variables, such as education, health, and livelihood have been augmented with SLI based on correlation analysis gives interesting inference for policy options as high educated tribal communities are positively correlated with high SLI and livelihood. Further, each of the SLI variable is decomposed using Correlation and Correspondence analysis for understanding the relative standing of the nine tribal sub communities in the three dimensional framework of high, medium and low SLI levels. Tribes with good education and employment (Malayarayan, Kuruma and Kurichya) have a better living standard and hence they can generally be termed as forward tribes whereas those with a low or poor education, employment and living standard indicators (Paniya, Adiya, Urali, Kattunaika, Muthuvans and Irula) are categorized as backward tribes

Customer satisfaction and retention are key issues for organizations in today’s competitive market place. As such, much research and revenue has been invested in developing accurate ways of assessing consumer satisfaction at both the macro (national) and micro (organizational) level, facilitating comparisons in performance both within and between industries. Since the instigation of the national customer satisfaction indices (CSI), partial least squares (PLS) has been used to estimate the CSI models in preference to structural equation models (SEM) because they do not rely on strict assumptions about the data. However, this choice was based upon some misconceptions about the use of SEM’s and does not take into consideration more recent advances in SEM, including estimation methods that are robust to non-normality and missing data. In this paper, both SEM and PLS approaches were compared by evaluating perceptions of the Isle of Man Post Office Products and Customer service using a CSI format. The new robust SEM procedures were found to be advantageous over PLS. Product quality was found to be the only driver of customer satisfaction, while image and satisfaction were the only predictors of loyalty, thus arguing for the specificity of postal services

En aquest estat de la qüestió, s’hi presenten els resultats d’una anàlisi sobre l’evolució i les característiques principals de les revistes de geografia incloses al Journal of Citation Reports dins de la versió del Social Science Citation Index i, per tant, amb factor d’impacte. El període d’estudi escollit ha estat el que va de 1997 a 2005, és a dir, al llarg dels darrers nou anys amb dades disponibles. En total, hi han aparegut incloses trenta-nou revistes, una bona part de les quals ha romàs a la llista durant tot el temps estudiat. Hi ha hagut deu publicacions que han estat situades entre les cinc amb més factor d’impacte de cada any, i cap no ha estat la primera més de dos anys seguits. S’han trobat divuit temàtiques diferents en el conjunt de les revistes, en destaquen les de caire generalista i les de geografia econòmica i regional. Una gran majoria dels volums està publicada per editorials, Blackwell Publishing n’és la més destacada. L’origen de les revistes és clarament anglosaxó, només n’hi trobem dues d’escrites en una altra llengua. La segona part de l’article descriu totes les publicacions contemplades en els nou anys estudiats, amb una petita ressenya de cadascuna

We analyze the Body Mass Index (BMI) in a distinct way of its traditional use and it lets us use it as a proxy of standard of living for the case of Colombia. Our approach is focused on studying how far the people are from the normal range and not on the score of each one and this lets us to treat equally extreme cases as severe thinness and obesity. We use a probabilistic model (Ordered Probit) that evaluates the probability of being within the normal range or another level. We found that socioeconomic variables have a significant effect on the dependent variable and that there are no linear effects. Besides, people with difficulties for walking and adults have less probability of having a normal BMI.

El documento busca mostrar las principales propiedades de un indicador de estándar de vida dentro del enfoque teórico de Amartya Sen. Establecemos un puente entre conceptos tales como: bienestar económico, bienestar, logro de agencia y estándar de vida. La metodología del Optimal scaling fue usada para probar las propiedades de Monotonicidad, No independencia de alternativas irrelevantes, Concavidad, informatividad y sustituibilidad.

Cr??dito variable de ampliaci??n para trabajar interdisciplinariamente las ??reas de Matem??ticas y Ciencias Sociales en los ??ltimos cursos de la ESO. Pretende que el alumno ampl??e el concepto de proporci??n para poder introducir las progresiones geom??tricas y la funci??n exponencial y consiste en la utilizaci??n de las variaciones porcentuales en el contexto del aumento del coste de la vida. Integra el siguiente tipo de material did??ctico: 1) Introducci??n al concepto de variaci??n perceptual. 2) Problemas de aplicaci??n para elaborar conceptos, trabajos fuera de clase, etc. 3) Trabajo de consolidaci??n: elaboraci??n de un IPC.

Delimitar el área de las dificultades del aprendizaje y conocer la panorámica actualizada de la investigación en esta área. El Current Index Journal Education (CIJE): todos los abstracts aparecidos bajo el epígrafe handicapped and gifted children, en el período 1980-1984, ambos inclusive. Estudio de la productividad de revistas. Impacto, vida media y ranking de las más productivas. Estudio de productividad de autores. Análisis de los autores más productivos. CIJE. Investigación bibliométrica: ley de Lotka, ley de dispersión de Bradford, índice de productividad total, índice de productividad fraccionaria, agrupamiento criterial de Crane. En cuanto a las revistas se codifican 81, con un total de 7287 artículos, siendo la media global de 90 artículos por revista. Una sola revista publica el 70 por ciento de la producción total. Con la ley de Bradford se hallan cuatro áreas de productividad: la primera área la forman cinco revistas que publican una media de 371'6 artículos. La segunda la forman 15 títulos con una media de 184'4 artículos, la tercera la forman 21 títulos con una media de 90 artículos. La cuarta la forman 40 títulos con una media de 42'2 artículos. Las revistas de las dos primeras áreas se publican todas en EEUU, excepto una. Para la jerarquización de autores se recurre al modelo de Crane: se encuentran 29 autores a los que incluir en grandes productores, 150 en el de productores moderados, 1220 aparecen como aspirantes y 5'190 como transeuntes. Los autores más productivos son: Frith, G., Kavale, K. A., Chandler, H. N., Torrance, E. Paul, Salend, S. J., Algozzine, B., Csapo, M., Forness, S., Stainback, W., Stainback, S., Ysseldike, J. Giordano, G. y Treffinger, D. Sería interesante realizar un estudio de las áreas temáticas.
