The cortisol response to surgery was studied in two groups of children one to eight years old during the first 24 hours after lower abdominal or peripheral surgery. The children were randomly allocated to a control (C) group (n = 6) or an epidural (E) group (n = 7). In Group C, surgery was performed under general anaesthesia and postoperative pain relief was achieved by using non-narcotic analg...

UNLABELLED Pancreatic stellate cells (PSC) are involved in fibrogenesis and oncogenesis by modulating the extracellular matrix. AIM To evaluate the effect of cellular stress on PSC activation using a model of normal human pancreatic tissue slices culture preserving the microenvironment. METHODS Thin sections (300 μm) of normal human pancreas were cultured under hyperoxia (90% O2) during 72 ...

Cast AZ31B-H24 magnesium alloy, comprising Mg with 3.27 wt% Al and 0.96 wt% Zn, was cold rolled and subsequently annealed. Global texture evolutions in the specimens were observed by X-ray diffractometry after the thermomechanical processing. Image-based microstructure and texture for the deformed, recrystallized, and grown grains were observed by electron backscattered diffractometry. Recrysta...

We use a firm-CEO assignment framework to model the market for CEO effective labor. In the model’s equilibrium more talented CEOs match with and supply more effort to larger firms. Taxation of CEO incomes affects the equilibrium pricing of CEO effective labor and, hence, spills over and affects firm profits. Absent the ability to tax profits or a direct concern for firm owners, a standard presc...

Previous research has identified non-diversifiable risk and a preference for “being one’s own boss” as key determinants of participation in self-employment. Using a simple model of occupational choice, I show how both factors can cause efficiency losses in a free market economy, and how linear differential occupational taxation can improve on the market outcome. A simulation exercise calibrated...

during the last two decades, decentralization has been supposed as a tool for making the public sector policies more efficient. despite the claimed benefits, there are some costs; some of decentralization theorists believe that devolution of pure public goods provision to local governments has led to the failure of decentralization policies. this article uses game theory to study the implicatio...

We examine the proposal by Peter Zweifel and Michael Breuer to combine risk-based premiums with a subsidy for individuals whose expenditure for health insurance exceeds a certain share of income. Assuming a maximin social welfare function and optimal linear income taxation, we find that this proposal is superior to social insurance if the correlation between productivity and health is not too l...
