Background: This study determined the pharmacokinetics of the contrast agent gadobutrol in marmosets by quantitative MRI to derive guidelines for neuroimaging protocols. Methods: Local concentrations of gadobutrol were determined from consecutive gradient echo-based mapping of the relaxation rate R1 on a clinical 3T MRI scanner. Half-time of renal elimination was measured after injection of a trip

The need to compare authors on the basis of their publications is well known. In this paper, we undertake an axiomatic analysis of the ways to measure academic authorship, for a given dataset of papers. We find that the intuitive Egalitarian index is the only index that satisfies efficiency, anonymity and monotonicity in terms of paper citation. This index divides authorship of joint projects equa

How does film become a political act? That is the question that the artistic research project Sisters! Making Films, Doing Politics revolves around. Taking Hannah Arendt’s ideas about the constitution of the political arena as its point of departure, this dissertation reflects on the aesthetic mechanisms that underlie contemporary strategies for collective and feminist filmmaking. Sisters! Making

Several recent models of choice build on the idea that decision makers are more likely to choose an option if its attributes stand out compared to the attributes of the available alternatives. One example is the model of focusing by Köszegi and Szeidl (2013) where decision makers focus disproportionally on the attributes in which the available options differ more, implying that some attributes wil

Using Swedish firm-level data on all firms and their affiliates abroad, we investigate what observable firm and country characteristics affect the size of affiliate firms in a particular destination. We employ the richness of the data to investigate the importance of destination country factors in explaining firm outward FDI activities and distinguish between the factors that affect such activitie

There is a strong general concern amongst policymakers worldwide that multinational enterprises engage in far-reaching tax-planning activities. It is generally thought that by using transfer pricing or other techniques to shift profits, multinational enterprises can avoid taxation and thereby erode tax bases. Several attempts have been made to tackle this problem, not least through the OECD/G20 in

In Sweden, asylum seekers are either deported or granted a residence permit. Refugee families with a residence permit are assigned to the different local municipalities. Since almost all accommodation options are exhausted in Sweden, households in some municipalities are asked to state their willingness to accommodate refugee families. In line with the European NGO “Refugees Welcome”, a refugee fa

Magnetic Resonance Spectroscopy (MRS) allows for the quantification of neurotransmitters, antioxidants, energy-metabolism, membrane components and cellular viability markers present in the brain. This technology has been used in preclinical studies and later extended to be used in humans, where it offers an attractive non-invasive approach complementary to other anatomical imaging modalities (e.g.

Hur och under vilka omständigheter definieras och inramas skolledarskap? Frågan ställs i detta kapitel till två slags texter som vid sidan av sina respektive huvudfunktioner just definierar och inramar skolledares görande. Det är, för det första, texter som reglerar rektorers uppdrag generellt och på nationell nivå, närmare bestämt styrdokument för den sedan 2010 obligatoriska rektorsutbildningen

Recently, there has been a rise of contributions in innovation and economic geography studies on how firms from specific industries and regional innovation systems (RISs) rely on international networks to innovate. So far, the focus has been on single cases, firms located in well-known RISs and international linkages, without really distinguishing those with geographically close partners from thos

Recent literature shows that differences in structural characteristics at country level are important determinants of the innovative capacities and growth performance of different countries. Based on firm-level data collected from a survey, this study identifies who are the world leaders, followers, and marginalised firms in a sample of nine countries and a selection of industries in terms of firm
