This study examined whether sense of coherence mediated relationships of perceived racial discrimination and of collective self-esteem to psychological distress (depression and anxiety) among 122 Vietnamese American college students. Higher levels of perceived racial discrimination (PRD) were associated with a reduced sense of coherence (SOC) and with(More)
In this paper we show how genetic programming can be used to discover useful texture feature extraction algorithms. Grey level histograms of different textures are used as inputs to the evolved programs. One dimensional K-means clustering is applied to the outputs and the tightness of the clusters is used as the fitness measure. To test generality, textures(More)
Our primary motivation in this paper is to determine whether evolved texture feature extraction programs are competitive with human derived programs for a difficult real world texture classification problem. The problem involves distinguishing images of three classes of bulk malt. There are subtle differences between the three classes. We have used a number(More)
This study investigated the factor structure of the Self-construal Scale, an important measure of interdependent and independent self-construal. An exploratory factor analysis with the principal component method and varimax rotation supported Singelis' original two-factor model (1994) for a sample of 152 Vietnamese-American high school adolescents recruited(More)
This paper describes an approach to evolving texture feature extraction programs using tree based genetic programming. The programs are evolved from a learning set of 13 textures selected from the Brodatz database. In the evolutionary phase, texture images are first "binarised" to 256 grey levels. An encoding of the positions of the black pixels is used as(More)
