We investigate the gap in math and science achievement of thirdand fourth-graders who live with a single parent versus those who live with two parents in 11 countries. The United States and New Zealand rank last among the countries we compare in terms of the equality of achievement between children from single-parent families and those from two-parent homes. Following a multilevel analysis, we ...

Wickramasinghe, I.P. (2014). Predicting the performance of batsmen in test cricket. J. Hum. Sport Exerc., 9(4), pp.744-751. Cricket is one of the team games played over 50 countries in different levels. Though the performance of each batsman in the team can be easily quantified, the prediction of player performance is arduous. This paper demonstrates a methodology to predict the performance of ...

Multilevel Models (MLM) have pioneered the analysis of hierarchical data, with two or more levels. Agent-Based Models (ABM) are also used to analyse social phenomena in which there are two or more levels involved. This paper addresses the integration between MLM and ABM. To provide a basis of comparison, we focus on differential school effectiveness analysis, where MLM has been well studied, us...

An integrative multilevel model of empowerment and job performance behaviours is advanced, building on Social Cognitive Theory (SCT). Empowerment climate is hypothesized as influencing individual and team performance behaviours directly and partially through individual and team (psychological) empowerment. Using survey responses from 380 individuals, nested in 115 project management teams, we t...

In the study of examination results much interest centres on comparisons of curriculum subjects entered and the correlation between these at individual and institution level based on data where not every individual takes all subjects. Such `missing' data are not missing at random because individuals deliberately select subjects that they wish to study according to criteria that will be associat...

A crucial problem in the statistical analysis of hierarchically structured data is the dependence of the observations at the lower levels. Multilevel modeling programs account for this dependence and in recent years these programs have been widely accepted. One of the major assumptions of the tests of signi2cance used in the multilevel programs is normality of the error distributions involved. ...

background: the study was developed in order to find a subset of potential factors, which affect birth distance pattern, regarding consideration on correlation of events of birth in a family and correlation within clusters/centers which other studies omit these correlations. methods: referring to documents that were registered for family in the health care centers on socio-economical zone, we c...
