abstract previous studies on willingness to communicate (wtc) have shown the influence of many individual or situational factors on students’ tendency to engage in classroom communication, in which wtc has been viewed either at the trait-level or situational level. however, due to the complexity of the notion of willingness to communicate, the present study suggests that these two strands are ...
in order to determine of some blood serum biochemical parameters in rainbow trout, blood samples were taken from the caudal vein of 531 apparently healthy rainbow trout cultured in earthen ponds. data was analyzes by regression analysis, pearson correlation coefficient test and fisher's test. the mean values of alp, ast, alt and ldh were 722±320, 337±150, 29±24 and 579±353 u/l and the mean...
Inference concerning the correlation coefficient of two random variables from the bivariate normal distribution has been investigated by many authors. In particular, Fisher [1915. Frequency distribution of the values of the correlation coefficient in samples from an indefinitely large population. Biometrika 10, 507–521] and Hotelling [1953. New light on the correlation coefficient and its trans...
the aim of this study was to determine the relationship between entrepreneurial personality characteristics and small and medium-sized sport enterprises start-up (smses). the methodology of this study was descriptive-correlation. population consisted of small and medium-sized sport enterprises (n=1500) and their owners and/or managers were randomly selected as the sample (n=258). for data colle...
BACKGROUND Through Diffusion Weighted Imaging (DWI), information related to early molecular changes, changes in the permeability of cell membranes, and early morphologic and physiologic changes such as cell swelling can be obtained. AIMS We investigated the correlation between the prognostic factors of breast cancer and apparent diffusion coefficient (ADC) in DWI sequences of malignant lesion...

History of Science and Statistical Education: Examples from Fisherian and Pearsonian schools Paper presented at the 2004 Joint Statistical Meeting, Toronto, Canada Chong Ho Yu, Ph.D. [email protected] website: http://www.creative-wisdom/pub/pub.html Abstract Many students share a popular misconception that statistics is a subject-free methodology derived from invariant and timeless mathematic...
Motivation Site directed mutagenesis is widely used to understand the structure and function of biomolecules. Computational prediction of mutation impacts on protein stability offers a fast, economical and potentially accurate alternative to laboratory mutagenesis. Most existing methods rely on geometric descriptions, this work introduces a topology based approach to provide an entirely new rep...
