This paper presents the method used to develop the ANU II status scores for all Australian occupations. For some purposes it supersedes ANU I, a 16-point scale (Broom, Jones, and Zubrzycki, 1965, Australian and New Zealand Journal of Sociology (Suppl.) 1; Broom and Jones, 1969, American Sociological Review 34, 650–658). The two scales correlate at .83. The new scale was calculated using a broad range of data applied to a prestige score criterion to estimate an equation used to predict status scores for all occupations. These scores are available in Broom, Duncan-Jones, Jones, and McDonnell (1977, Investigating Social Mobility) along with further details of the method and results. The new scale is currently being used in the analysis of the ANU 1973 survey of social mobility in Australia, and in the reanalysis of data from the ANU 1965 survey. Preliminary results (also presented in Broom et al., 1977) indicate that the scale will be comparable both across time in Australia and across space when comparisons with the “second generation” of mobility studies is undertaken. 相似文献

By definition, the subjective probability distribution of a random event is revealed by the (‘rational’) subject's choice between bets — a view expressed by F. Ramsey, B. De Finetti, L. J. Savage and traceable to E. Borel and, it can be argued, to T. Bayes. Since hypotheses are not observable events, no bet can be made, and paid off, on a hypothesis. The subjective probability distribution of hypotheses (or of a parameter, as in the current ‘Bayesian’ statistical literature) is therefore a figure of speech, an ‘as if’, justifiable in the limit. Given a long sequence of previous observations, the subjective posterior probabilities of events still to be observed are derived by using a mathematical expression that would approximate the subjective probability distribution of hypotheses, if these could be bet on. This position was taken by most, but not all, respondents to a ‘Round Robin’ initiated by J. Marschak after M. H. De-Groot's talk on Stopping Rules presented at the UCLA Interdisciplinary Colloquium on Mathematics in Behavioral Sciences. Other participants: K. Borch, H. Chernoif, R. Dorfman, W. Edwards, T. S. Ferguson, G. Graves, K. Miyasawa, P. Randolph, L. J. Savage, R. Schlaifer, R. L. Winkler. Attention is also drawn to K. Borch's article in this issue. 相似文献

A Bayesian method is proposed for estimating the cell probabilities of several multinomial distributions. Parameters of different distributions are taken to be a priori exchangeable. The prior specification is based upon mixtures of a hierarchical distribution, referred to as the multivariate “Dirichlet-Dirichlet” distribution. The analysis is facilitated by a multinomial approximation relating to the multinomial-Dirichlet distribution. The posterior estimates depend upon measures of entropy for the various distributions and shrink the individual observed proportions towards values obtained by pooling the data across the distributions. As well as incorporating prior information they are particularly useful when some of the cell frequencies are zero. We use them to investigate a numerical classification of males of various vocations, according to cause of death. 相似文献

This paper assesses ownership of 16 financial products by households in different lifecycle stages amongst four ethnic groups (Africans, Coloureds, Asians, and Whites) in South Africa. The lifecycle hypothesis indicates younger households should own more debt-related financial products, whereas households in intermediate lifecycle stages should own more financial products to accumulate assets; both these claims are disconfirmed for all groups. However, White households in intermediate household stages own more financial products than younger and older households, consistent with previously reported lifecycle findings in Western countries. Consistent with the literature on innovation adoption we find that younger, affluent and highly educated households amongst the other three ethnic groups tend to own more financial products than older Africans, Coloureds and Asians. These results indicate that innovation adoption literature may better describe financial product ownership in developing countries than the lifecycle hypothesis. 相似文献

The present study investigated the prevalence of gambling behaviors among 71 individuals recovering from substance-dependent disorders and living in self-run recovery homes (Oxford Houses). Residents were given the South Oaks Gambling Screen to assess gambling behaviors and pathological gambling, and 19.7% of the sample was identified as having probable pathological gambling. These residents reported proportionately more involvement in a variety of gambling behaviors than other residents. Engagement in various gambling activities was consistent with previous investigations and suggested that self-run recovery homes such as Oxford Houses might be suitable referral sources for recovering persons who have comorbid gambling problems. 相似文献

We use a controlled experiment to explore whether there are gender differences in selecting into competitive environments across two distinct societies: the Maasai in Tanzania and the Khasi in India. One unique aspect of these societies is that the Maasai represent a textbook example of a patriarchal society, whereas the Khasi are matrilineal. Similar to the extant evidence drawn from experiments executed in Western cultures, Maasai men opt to compete at roughly twice the rate as Maasai women. Interestingly, this result is reversed among the Khasi, where women choose the competitive environment more often than Khasi men, and even choose to compete weakly more often than Maasai men. These results provide insights into the underpinnings of the factors hypothesized to be determinants of the observed gender differences in selecting into competitive environments. 相似文献

An (n×n)/ksemi-Latin square is an n×n square array in which nk distinct symbols (representing treatments) are placed in such a way that there are exactly k symbols in each cell (row–column intersection) and each symbol occurs once in each row and once in each column. Semi-Latin squares form a class of row–column designs generalising Latin squares, and have applications in areas including the design of agricultural experiments, consumer testing, and via their duals, human–machine interaction. In the present paper, new theoretical and computational methods are developed to determine optimal or efficient (n×n)/k semi-Latin squares for values of n and k for which such semi-Latin squares were previously unknown. The concept of subsquares of uniform semi-Latin squares is studied, new applications of the DESIGN package for GAP are developed, and exact algebraic computational techniques for comparing efficiency measures of binary equireplicate block designs are described. Applications include the complete enumeration of the (4×4)/k semi-Latin squares for k=2,…,10, and the determination of those that are A-, D-, and E-optimal, the construction of efficient (6×6)/k semi-Latin squares for k=4,5,6, and counterexamples to a long-standing conjecture of R.A. Bailey and to a similar conjecture of D. Bedford and R.M. Whitaker. 相似文献
