the present study investigated the mediating role of organizational citizenship behavior (ocb) in the relationship between job satisfaction, turnover, and organizational identification. the population of the present study included all employees working at tehran municipality at district 2 and the sample consisted of 260 employees selected using random sampling and cochran formula. the research ...
Structural equation modeling (SEM) with ordinal indicators rely on an assumption of categorized normality. This assumption may be tested for pairs of variables using the likelihood ratio G or Pearson’s X statistics. For increased computational efficiency, SEM programs usually estimate polychoric correlations in two stages. However, two-stage polychoric estimates are not asymptotically efficient...
هدف اصلی ما در این پایان نامه، مطالعه عملگردهای مثبت و نگاشت های حالت روی * – جبرهای باناخ و –c* جبرها می باشد. در وهله بعدی *- ایزومورفیسم های بین –c* جبرهای یکدار را مورد مطالعه قرای می دهیم . علاوه بر موارد فوق، پایداری –j* مشتقها روی –j* جبرها را به عنوان کاربردی از قضیه نقطه ثابت تعمیم یافته مورد مطالعه قرار می دهیم و نهایتا با پیدا کردن حل عمومی برای معادله تابعی ترکیبی چهارتایی جمعی، درج...
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
Likelihood ratio criteria are developed for hypotheses concerning multivariate regression matrices when reduced rank is assumed or equivalently hypotheses concerning linear restrictions on regression matrices. In an econometric simultaneous equation model a single restriction may be called a ”structural equation.” A model of reduced rank in statistics is often termed a ”linear functional relati...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
The purpose of this study is to investigate the impact of estimation techniques and sample sizes on model fit indices in structural equation models constructed according to the number of exogenous latent variables under multivariate normality. The performances of fit indices are compared by considering effects of related factors. The Ratio Chi-square Test Statistic to Degree of Freedom, Root Me...
