Social connectedness, discrimination, and social status as mediators of acculturation/enculturation and well-being

The present study proposed and tested a conceptual model of acculturation/enculturation and subjective well-being (SWB) by including social connectedness in mainstream society, social connectedness in the ethnic community, perceived discrimination, and expected social status as mediators. Survey data from 273 Asian American college students in the midwest were analyzed by using structural equation modeling. Results indicated that the effect of acculturation on SWB was mediated by social connectedness in mainstream and ethnic communities and expected social status, whereas the effect of enculturation on SWB was mediated by social connectedness in the ethnic community and expected social status. Contrary to the authors' hypothesis, perceived discrimination did not mediate the relation of acculturation and SWB, but indirectly influenced SWB via a lowered sense of connectedness to mainstream society. Approximately 46% of the variance in SWB was accounted for by the variables included in this model. Implications for theory, research, and practice are discussed.     

SUBSTANCE: THINGS AND STUFFS

The categorial concepts of substance (thing) and substance (stuff) are described, and the conceptual relationships between things and their constitutive stuff delineated. The relationship between substance concepts, expressed by other count-nouns, and natural kind concepts is examined. Artefacts and their parts are argued to be substances, whereas parts of organisms are not. The confusions of seventeenth- and eighteenth-century philosophers who invoked the concept of substance are adumbrated.     

External thought—does sketching assist problem analysis?

An experimental study (n = 60 students) tests the advantages of being allowed to sketch a representation of a mechanical system (involving components such as weights, ropes and pulleys) when one is to be subsequently asked questions about this system. In comparison to a control group who were not allowed to sketch the system, the main advantages of sketching were found to be a reduction in the perceived difficulty of the problems and an increase in the likelihood of correctly inferring relations between the components. These advantages came at no extra cost in terms of additional time being needed to analyse the situation or solve the problems. However, sketching conferred no advantage in terms of the correct recall of system components. Copyright © 2004 John Wiley & Sons, Ltd.
