This study examines the relationship between trade and the quality of economic institutions under different political institutions. It uses panel data of 138 countries from 1984 to 2010 and employs instrumental variables and identification through heteroscedasticity to mitigate the problem of endogeneity. The findings suggest that the effect of trade on economic institutions reduces significantly

Purpose– This paper aims to present a study of the role of prior start‐up experience as a source of learning in the entrepreneurial process. Three learning outcomes are examined with respect to a comparison between habitual and novice entrepreneurs: skills for coping with liabilities of newness, preference for effectual reasoning, and attitudes towards failure.Design/methodology/approach– This is

Background: Eutrophication of aquatic environments is a major environmental problem in large parts of the world. In Europe, EU legislation (the Water Framework Directive and the Marine Strategy Framework Directive), international conventions (OSPAR, HELCOM) and national environmental objectives emphasize the need to reduce the input of nutrients to freshwater and marine environments. A widely used

The electronic spectrum of the azurin Met121Gln mutant, a model of the blue copper protein stellacyanin, has been studied by ab initio multiconfigurational second-order perturbation theory (the CASPT2 method), including the effect of the protein and solvent by point charges. The six lowest electronic transitions have been calculated and assigned with an error of less than 2400 cm-1. The ground-sta

The late Ediacaran–mid Cambrian occurrence s of phosphorites in the wes-tern Mediterranean region (West Gondwana) and southern Sweden (north -west Baltica) are related to the poleward drift of West Gondwana and thenorthern drift of Baltica. As a result, these regions crossed subtropical andtemperate palaeolatitudes of the Southern Hemisphere, in which oceanicupwelling and high organic productivity

Baltoskandien utgör en del av paleokontinenten Baltica, vilken mestadels var täckt av ett grunt epeiriskt hav under den ordoviciska tidsperioden (ca 485,5–444 Ma). Detta uråldriga hav efterlämnade en tunn lagerföljd av sedimentära bergarter. Under tidig–mellanordovicium (ca 485,5–457,5 Ma) befann sig Baltica vid tempererade breddgrader på södra halvklotet och kallvattenkarbonater bildades över stoThe Baltoscandian region forms part of the paleocontinent Baltica, which was largely covered by a shallow epeiric sea throughout much of the Ordovician (c. 485.5–444 Ma). This ancient sea is today recorded by a thin succession of sedimentary rocks. During the Early–Middle Ordovician (c. 485.5–457.5 Ma), Baltica was situated in mid-latitudes on the southern hemisphere and cool-water carbonates form

Purpose: The aim of this paper is to review the evidence of the association between energy balance and obesity. Methods: In December 2015, the International Agency for Research on Cancer (IARC), Lyon, France convened a Working Group of international experts to review the evidence regarding energy balance and obesity, with a focus on Low and Middle Income Countries (LMIC). Results: The global epide

This study examines the causal effects of birth weight on two health-related outcomes: inpatient hospitalizations and sickness absences, distinguishing between different diagnoses. Our analysis exploits differences within siblings and within twin pairs, using full population Swedish register data on cohorts born between 1973 and 1995, observed through childhood and in adulthood. In childhood, ther
