Dissemination of Acinetobacter baumannii strains in different units of a hospital in Sorocaba, São Paulo, Brazil was evaluated over a period of two years. By using biotyping, serotyping and ribotyping, 27 distinct clones were differentiated among 76 strains isolated between 1993-94, from clinical specimens of hospitalized patients. Two clones, 2:O4:A (biotype:serotype:ribotype) and 2:O29:A acco...

The aim of this paper is to understand the impact of optimal provision of both risk and incentives on the choice of contracting partners. I study a risky setting where heterogeneously risk-averse employers and employees must match to be productive. They face a standard onesided moral hazard problem: mean output increases in the noncontractible input of the employee. Better insurance comes at th...

My thesis explored three different synthesis routes toward obtaining monodisperse clutches of well-ordered nanoparticles stabilized by various alkanethiols. The first two synthesis methods were based on a two-phase system employing first tetraoctylammonium bromide (TOAB) as a phase transfer catalyst and then didodecyldimethylammonium bromide (DDAB). Though these methods approximated what could ...

This article examines the determinants of the pattern of protection across products in the Brazilian agricultural sector from 1969 to 1989. Three key determinants of policy are explored: interest group pressure, government objectives, and structural change associated with economic crisis and a change in political regime. The principal agricultural policies are analyzed, and nominal protection c...

The Green Revolution, which bolstered agricultural yields and economic well-being in Asia Latin America beginning the 1960s, largely bypassed sub-Saharan Africa. We study first randomized controlled trial of a government-implemented input subsidy program (ISP) Africa intended to foment Revolution. find that this temporary for Mozambican maize farmers stimulates Revolution technology adoption le...

A central pillar of the sustainability movement is the call to include environmental accounting in standard measures of economic performance. This increased transparency would, in principle, mitigate the temptation of economic managers and policy makers to increase growth in material consumption at the expense of the environment. Moreover, as Repetto (1989) and others have argued, deducting dep...

This paper deals with the determinants of labour out-migration from agriculture across 153 EU regions over the 1990-2008 period. The central aim is to shed light on the role played by CAP payments on this important adjustment process. Using static and dynamic panel data methods, we show that standard neo-classic drivers, like the relative income and the relative labour share, represented signif...
