This study aims to determine the influence of disciplinary development in teaching and learning process on work ethic teachers at SDN 16 Bulu Tellue Kecamatan Tondong Tallasa Kabupaten Pangkep. The method that researchers use is quantitative research with a descriptive approach. Data collection closed questionnaires. analysis through statistics inferential statistics. results suggest (1) Discip...
In this paper, the estimation problem of generalized Rayleigh distribution is considered. The parameters are estimated using likelihood based inferential procedure: classical as well as Bayesian. We have computed MLEs and Bayes estimates under gamma priors along with their asymptotic confidence, bootstrap and HPD intervals. The Bayesian estimates of the parameters of generalized Rayleigh distri...
Background and Aim: Current study perform to examine the relation between attachment styles and social adjustment. Material and method: the method of this study was descriptive in kind of correlation .the method of sampling was multiple cluster sampling including 150 Bu-Ali Sina University students. Attachment styles was evaluated by Adult Attachment Scale (AAS) and social adjustment evalu...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
The Gini index represents a special case of the generalized Gini indices, which permit to choose a level of inequality aversion and to stress the different proportions of the income distribution. In order to apply these indices to income sample data, it is necessary to use reliable inferential procedures. In fact, also if often in income studies we have large samples for which the precision of ...
Inference for the Lognormal Mean and Quantiles Based on Samples With Left and Right Type I Censoring
Interval estimation of the mean and quantiles of a lognormal distribution is addressed based on a type I singly censored sample. A special case of interest is that of a sample containing values below a single detection limit. Generalized inferential procedures which utilize MLE based approximate pivotal quantities, and some likelihood based methods, are proposed. The latter include methodology ...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
the space now known as complete erdos space ec was introduced by paul erdos in 1940 as the closed subspace of the hilbert space ?2 consisting of all vectors such that every coordinate is in the convergent sequence {0} ? { 1 n : n ? n}. in a solution to a problem posed by lex g. oversteegen we present simple and useful topological characterizations of ec. as an application we determine the ...
