Social capital is a multi-faceted phenomenon in social sciences that massively affects many social fields. It can be a helpful factor in promoting health. Among the groups with high burnout, nurses have always shown higher levels of burnout. Studies have revealed that social capital can be an important factor affecting burnout. This study aimed to determine the extent of the effect of social ca...

a simple and reliable stability-indicating rp-hplc method was developed and validated for analysis of adefovir dipivoxil (adv).the chromatographic separation was performed on a c18 column using a mixture of acetonitrile-citrate buffer (10 mm at ph 5.2) 36:64 (%v/v) as mobile phase, at a flow rate of 1.5 ml/min. detection was carried out at 260 nm and a sharp peak was obtained for adv at a reten...

in the present study, the energetic and economic modeling of lentil and chickpea production in esfahan province of iran was conducted using adaptive neuro-fuzzy inference system (anfis) and linear regression. data were taken by interviewing and visiting of 140 lentil farms and 110 chickpea farms during 2014-2015 production period. the results showed that the yield and total energy consumption w...

Multiple linear regression analysis is widely used to link an outcome with predictors for better understanding of the behaviour of the outcome of interest. Usually, under the assumption that the errors follow a normal distribution, the coefficients of the model are estimated by minimizing the sum of squared deviations. A new approach based on maximum likelihood estimation is proposed for findin...

This paper presents a straightforward regression test of parametric and semiparametric index models against more general semiparametric and nonparametric alternative models. The test is based on the regression coefficient of the restricted model residuals on the fitted values of the more general model. A goodness-of-fit interpretation is shown for the regression coefficient, and the test is bas...

This paper uses a Jle.rrhle leust squares (FLS) time-varying linear regression technique to investiaate coefficient stabilitv for the Goldfeld U.S. money demand model over the period 1959:62 to 19X5:Q3. Time paths traced out by the FLS coefficient estimates exhibit shifts in 1974 and 1983; but these shifts are small relative to a persistent downward trend in the estimated coefficient for the in...

in order to evaluate the response of emergence rate of oil seed rape seedlings to temperature, a pot experiment was conducted to assess the relationship between emergence rate of three rape seed cultivars (apetalous flower, rgs003 and syn3) by using a non-linear regression against temperature variation. six models (tooth shape, segmented, beta, curve, quadratic and cubic) were used and the supe...

One of the problems in research on symptom perception during histamine challenge has been the difficulty in finding both a valid and practical parameter of the "perceptiveness" for bronchoconstriction in a subject. The purpose of this study was to validate whether the slope in the linear regression model between stimulus and sensation during histamine challenge is an appropriate index for the "...
