Despite a number of studies in the field of job satisfaction, there are still some problematic areas left. A question, which still lacks explanation, is whether specific sample may be evaluated using instruments which were primarily developed based on a different type of a sample than the one under research. With regard to the problematic area, we generated the purpose for our research. The pur...

the present research is concerned with the determination of ductility, over-strength and response modification factors of coupled steel shear wall frames. three structural models with various numbers of stories, bay width and coupling beam height were analyzed using static pushover and incremental nonlinear dynamic analyses. the ductility, over-strength and response modification factors for the...

Variable dimension models are problems where the parameter space is not well defined, therefore the sample space is a infinite collection of unrelated subspaces. If the considered statistical model is not defined in concise way, then the dimensionality of the parameter space can also be part of the model uncertainty. These problems have been studied in the context of Bayesian model comparison a...

Factor and suffix oracles have been introduced in [1] in order to provide an economic and efficient solution for storing all the factors and suffixes respectively of a given text. Whereas good estimations exist for the size of the factor/suffix oracle in the worst case, no average-case analysis has been done until now. In this paper, we give an estimation of the average size for the factor/suff...

The propose of this study is to investigate the factor structures of the W-DEQ, originally developed on UK and Swedish women, were confirmed in Turkish samples, and to obtain a new modified factor structure appropriate to Turkish culture. Statistical analyses of the data obtained were performed using SPSS for Windows version 13.0 and the SAS statistical software Version 9.1. Both confirmatory a...
