A conformity index is a measure of how well the volume of a radiosurgical dose distribution conforms to the size and shape of a target volume. Because the success of radiosurgery is related to the extremely conformal irradiation of the target, an accurate method for describing this parameter is important. Existing conformity ratios and indices used in radiosurgery are reviewed and criticized. I...

objective: the aim of this study is to explore the confirmatory factor analysis results of the persian adaptation of abbreviated math anxiety scale (amas), proposed by hopko, mahadevan, bare & hunt. method: the validity and reliability assessments of the scale were performed on 298 college students chosen randomly from tabriz university in iran. the confirmatory factor analysis (cfa) was carrie...

OBJECTIVE The aim of this study was to investigate cross-national differences (1) in the four-dimensional factor structure of drinking motives; (2) in the mean levels of enhancement, coping, social, and conformity motives; and (3) in the association of these motives with adolescent alcohol use, risky single-occasion drinking, and alcohol-related problems. METHOD Confirmatory factor analysis, ...

BACKGROUND Conformity is a psychological variable related to the propensity of an individual to match his or her behavior and opinion to the perceived social and cultural norm, even if these do not represent the true beliefs of the person. The aim of the present study was to investigate whether the psychological variable of conformity is different in two distinct modes of renal replacement ther...

The genetical analysis of covariance structures is used to explore the genetical and environmental intercorrelations of impulsiveness and sensation seeking factors and their conformity to Eysenck's principal personality dimensions. The independent dimensions of psychoticism, extraversion, neuroticism, and lie scale are not found to give a very satisfactory account of the genetical factor struct...

Creating rankings of academic journals is an important but contentious issue. It is of especial interest in the UK at this time (late 2005) as we are only two years away from the submission date for the next Research Assessment Exercise (RAE) the importance of which, for UK universities, can hardly be overstated. The purpose of this paper is to present a journal ranking for business and managem...

This study adapted and extended M. L. Cooper's (1994) Drinking Motives Measure to examine marijuana motives among 299 college students. An exploratory factor analysis supported the hypothesized 5-factor marijuana motives model, resulting in enhancement, conformity, expansion, coping, and social motives. Analyses supported the internal consistency and concurrent validity of the 5 marijuana motiv...

the main purpose of this research is designing model of factors that affect utilization of policy research with concept mapping technique and verifying it. for this in three stage, sequential-exploratory mixed methods design is used. in first stage, literature review, interview and focus group is used for identifying factors. the analysis is used for analyzing data. in second stage for designin...

A method is proposed to measure the difference between a given mesh and the size specification map that this mesh is supposed to satisfy. The size specification map is given in the form of a Riemannian metric that specifies both size and stretching of the mesh to be build. The measure evaluates the difference between the unique metric for which a simplex is a unit equilateral simplex, and the a...
