Immigration and the Changing Population of New South Wales and Sydney with Implications for Education and Health Services

The problem of economic and social support for the dependant sectors of the Australian population in the future is addressed through consideration of recent national and regional population projections in relation to dependency theory. The level of immigration required to prevent the dependent sectors growing unduly at the expense of the productive is shown to be significant and this is complicated by high unemployment, and the issue of how many immigrants that can continue to be absorbed into the workforce. The contribution of suburban development trends, with their often wasteful provision of services at the local level in the longer term, as the result of regional demographic change, is seen to exacerbate the problems at the national level.     

Unemployment in Poland - causes and remedial measures

This article describes unemployment and labor market policy in Poland after 1989. The analysis is based on official statistics, legislation and Polish social science literature. The unemployment situation in Poland is continually changing. Conclusions drawn by social scientists in 1991 and 1992 no longer give an adequate account of labor market trends in 1995. Steeply rising unemployment is the most traumatic upheaval in post-Communist Polish society. At the end of 1989, the number of people looking for work in Poland was far less than the number of available jobs. But by the end of 1992 there were 62 job-seekers for every job opening, dropping to 56 in September 1994. The social problems associated with unemployment vary from region to region. Women and young people predominate among the unemployed. The Polish government set up a Work Fund in January 1990 to alleviate unemployment. The Work Fund is the first real measure taken to assist the unemployed, but new legislation is needed if it is to become more effective.     

BANK RESERVE REQUIREMENTS AS AN IMPEDIMENT TO SIGNALING

Effective legal reserve requirements may hamper the private capital market's ability to price bank deposits. In the model developed here, the market has less information about bank assets than the banks have, and a bank can therefore signal its superior information through its choice of excess reserves. Mandatory reserves can inhibit such signaling and therefore result in inefficient deposit pricing.     

Social Ecology of Premature Mortality in Three Australian Cities

Variations in mortality from ischaemic heart disease and cancer in the age group 50–64 for the period 1969–1973 inclusive were found to be statistically highly significant, with the highest incidences in certain inner local government areas (LGA) and some exurban LGAs. Correlation and regression analysis were undertaken between a small number of social indicator independent variables and the dependent mortality variables. These variables represented three constructs, social isolation-housing class, crowding-density and socioeconomic status which together accounted for more than 40% of the variance in Sydney and Adelaide, but not in Melbourne, although the relationship there was still highly significant. Schematic models of factors in higher or lower disease incidence in particular areas are presented in the concluding section.     

The Equivalence of Two Proportions Revisited

The classic conditional test for checking that the difference between two independent proportions is not null may not be appropriate in many circumstances. Dunnett & Gent (1977) showed that in clinical trials, in studies of drugs, etc, the aim is to prove the practical equality (equivalence) of both proportions. On other occasions the aim may be the opposite: i.e. to prove that the two proportions are substantially different (biologically significant). Both cases are usually solved by two one-sided tests (TOST test). In this article, this procedure is shown to be conservative and two true two-sided tests for each case are proposed.     

Variation in Cancer Risk Estimates for Exposure to Powerline Frequency Electromagnetic Fields: A Meta-Analysis Comparing EMF Measurement Methods

We used meta-analysis to synthesize the findings from eleven case-control studies on cancer risks in humans exposed to 50-60 Hertz powerline electromagnetic fields (EMFs). Pooled estimates of risk are derived for different EMF measurement methods and types of cancer. EMF measurement methods are classified as: wiring configuration codes, distance to power distribution equipment, spot measurements of magnetic fields, and calculated indices based on distance to power distribution equipment and historic load data. Pooled odds ratios depicting the risk of cancer by each measurement type are presented for all cancers combined, leukemia for all age groups and childhood leukemia. The wire code measurement technique was associated with a significantly increased risk for all three cancer types, while spot measures consistently showed non-significant odds ratios. Distance measures and the calculated indices produced risk estimates which were significant only for leukemia.     

A cross-cultural investigation of the shared values relationship

Data from managers in Australia (N=505) and Hong Kong (N=653) support the findings of studies using American managers and their companies that shared values, or person-organization values fit, is strongly related to positive work attitudes. This relationship is unaffected by culture, as two-way analysis of variance reveals no interaction effect between shared values and country. Managerial implications are discussed.     

The role and function of drinking games in a university community

Understanding the role of drinking games in college student life is critical for program planners who wish to develop education and prevention programs to reduce abusive drinking. Drinking games are popular social activities that provide a focus for social interactions but place students at considerable risk for serious consequences. This article reports preliminary results of a study using participant observation and in-depth interviews to develop a typology of drinking games and describe patterns and practices associated with the games.
