Leaving welfare and employment are modeled and estimated simultaneously to determine which outcome has the greatest influence on the other. Wage outcomes and the relative influence of policy/economic versus demographic change in determining outcomes are also explored. Pooled cross-sectional data are used from six urban areas in six different states allowing a comparison across both economic and...

BACKGROUND Street children are an increasing problem in Latin America. It is however difficult to estimate the number of children in the street as this is a highly mobile population. AIMS To estimate the number of street children in Aracaju, northeast Brazil, and describe the characteristics of this population. METHODS Three independent lists of street children were constructed from a non-g...

Fifty juvenile offenders and 50 non-offending controls completed measures of language processing and production, and measures of social skill and IQ. Information about type of offending, substance use histories and learning/literacy problems was also gathered.Young offenders ...

Suppose that water towers like those shown in Figure 1 are initially filled with water and have the same volume, height, and cross-sectional outlet area. Which one empties first? This problem arises naturally when designing watersupplying tanks or funnels. We find a formula expressing the emptying time as a function of the volume of liquid and its initial height. We compute the emptying time fo...

BACKGROUND Stepped wedge cluster randomised trials frequently involve a relatively small number of clusters. The most common frameworks used to analyse data from these types of trials are generalised estimating equations and generalised linear mixed models. A topic of much research into these methods has been their application to cluster randomised trial data and, in particular, the number of c...

This paper examines the influence of demographic and economic cycles on the migration propensities given in the migration age schedule. It is well known that while the shape or profile of the migration-age relationship has enduring regularity over time and space, its level (or intensity) shows considerable volatility. Recent studies suggest that variations in generation size and economic condit...

This paper looks at the cross-section of stock returns for the particular case of emerging markets. For each of 21 emerging markets I investigate the role of a set of a priori specified factors in the cross-section of returns, and subsequently assess whether the important factors are common. I use new data on emerging markets’ individual stocks from the Emerging Markets Data Base. My results in...

BACKGROUND Age at menarche is known to be regulated by genetic and environmental factors. To date, no menarcheal data are available on North Korean women. In this cross-sectional survey, we investigated age at menarche and its possible influencing factors in North Korean refugees. METHODS Four hundred and eleven North Korean refugees were surveyed at a North Korean female refugee camp using a...
