An Exploration Of The Relationship Between Changing Inequality Of Individual,Household And Regional Inequality In Australian Cities

The changes in neighbourhood income inequality noted in Gregory and Hunter (1995) indicate that significant changes in the nature of Australian cities have occurred since the mid-1970s. This paper seeks to establish that the regional dimension of income inequality is becoming a more important component of overall inequality. Furthermore, low status and high status areas are becoming increasingly homogenous with more low income households living together in low status neighbourhoods and higher income households living elsewhere. The inadequacies of the regional income data currently available means that it is difficult to explore changes in social welfare in any detail.     

A longitudinal study of the social and academic competence of economically disadvantaged bilingual preschool children.

This longitudinal study was conducted to gain understanding of the social–emotional and academic development of economically disadvantaged bilingual preschool children. In Study 1, the authors combined cognitive, psychosocial, and cultural-linguistic factors to determine profiles of social competence as measured by peer play. A person-centered analysis of 207 Hispanic American preschoolers (ages 4 and 5 years) yielded 6 distinct profiles, 2 of which were socially competent and 1 of which was vulnerable. Findings revealed profile differences in social competence and a significant relationship between bilingualism and social–emotional development. In Study 2, the authors determined which profiles were associated with later academic achievement and growth of English proficiency. Findings indicated a significant relationship of early social–emotional development to later academic success and English acquisition, highlighting the role of bilingualism.

Investigating the Social Dimensions of Transport Disadvantage—I. Towards New Concepts and Methods

This article is the first of two papers that engage critically and productively with the relationship between the socio-economic transformations of cities, the differentiation of vulnerable groups within urban space and the distribution of transport services. This article undertakes a comprehensive review of the major conceptual and methodological approaches by which scholars and policy researchers have sought to address the connection between social disadvantage and access to transport. The article critically assesses the relative merits of various spatial analytical methodologies in illuminating social-transport links. The study finds that there is a need for greater sophistication in the use of analytical methods in transport research as well as an imperative for greater sensitivity to social differentiation within urban areas and relative to infrastructure and services. The article concludes by developing a method for combining spatial social and transport service data that is then deployed in the empirical case study reported in the second paper.
