Time series analysis of the relationship between unemployment and mortality: a survey of econometric critiques and replications of Brenner's studies.

M. Harvey Brenner's numerous time-series analyses of the relationship between population mortality rates and aggregate unemployment rates have attracted considerable attention from academics, policy-makers and the mass-media. Over the course of the last few years, however, Brenner's studies have begun to be subjected to critical scrutiny by econometricians. This paper provides a survey of these studies and concludes that--contrary to what is often claimed--Brenner's analyses do not provide convincing evidence that the social costs of unemployment include premature deaths.

The role of cartilage canals in the formation of secondary centres of ossification.

The present studies indicate that in the growth of cartilage canals the cartilage is removed by chondroclasts which stem from the primitive connective tissue cells of the perichondrium. Besides fusing to form multinucleated chondroclasts, these cells also provide the osteoblasts which establish the secondary centre of ossification. The growing tips of the blood vessels within the canals are also fashioned from these primitive connective tissue cells as they invade the microhaemorrhages at the ends of the canals. This is an identical procedure to that found in the vascular invasion of the primary growth plate. The cartilage canals are clearly useful sites in which to study the development of osteoclasts and chondroclasts from more primitive (osteoprogenitor) cells.

Measuring inequalities in health in the presence of multiple-category morbidity indicators.

This paper considers the problems which arise in seeking to measure socioeconomic inequalities in health when the health indicator is a categorical variable, such as self-assessed health. It shows that the standard approach--which involves dichotomizing the categorical variable--is unreliable. The degree of measured inequality is found to depend on the cut-off point chosen and the choice of cut-off point to affect the conclusions one can reach about trends in or differences in health inequality. The paper goes on to propose an alternative approach which involves constructing a latent health variable and then measuring inequalities in this latent variable by means of a variant of the health concentration curve.
