Seven diabetic girls who presented with cyclical disturbance of diabetic control before the menarche are described. In six girls cyclical hyperglycaemia occurred and in one cyclical hypoglycaemia. The index case is described in detail, and is then included in a description of the main clinical features of all seven cases. Cyclical disturbance of diabetic control may present in diabetic girls fr...

This paper modifies the standard Mortensen-Pissarides job matching model in order to explain the cyclical behavior of vacancies and unemployment. The modifications include strategic wage bargaining (Hall and Milgrom, 2006) and convex labor adjustment costs. The results reveal that our model replicates the cyclical behavior of both variables remarkably well. First, we show that strategic wage ba...

Growth ring analysis on silicified coniferous woods from the Missão Velha Formation (Araripe Basin - Brazil) has yielded important information about periodicity of wood production during the Early Cretaceous in the equatorial belt. Despite warm temperatures, dendrological data indicate that the climate was characterized by cyclical alternation of dry and rainy periods influenced by cyclical pre...

Cyclical mastalgia is a common complaint, with a potentially important relationship to breast cancer risk. In the last decade, case-control studies have reported that cyclical mastalgia could be considered as an independent risk factor for breast cancer. The subjectivity of a retrospectively collected symptom questioned the validity of this finding. We have examined the association between cycl...

This paper analyzes the welfare costs of business cycles when workers face uninsurable job displacement risk that has a cyclical component. Using a simple general equilibrium model with incomplete markets, this paper shows the following result: for sufficiently high degree of risk aversion (at least one), cyclical variations in the long-term earnings losses of displaced workers can generate arb...

I am induced to make some remarks upon this subject of obstinate vomiting in pregnancy, from the fact that within the last five years three cases of albuminuria during gestation have come under my observation, in all of which untoward results occurred, and in two of these obstinate vomiting was the prominent symptom. In one of the cases?the only one of which I mean to give complete details, the...

With governments worldwide attempting to increase the labour force participation of older workers in the context of ageing populations, both older workers marginally attached to the labour force (discouraged workers), and those whose labour force participation is affected by cyclical fluctuations (via the discouraged worker effect), are of particular interest to policy makers. Analysis of OECD ...
