We look at the link between the volatility in the Bitcoin market and the volatility in other related traditional markets, i.e. the gold, currency and stock market. We also try to answer if the volatility in the Bitcoin market can be explained by retail investor-driven internet search volumes or, perhaps, by the general level of risk in the financial system, as measured by two market-wide risk indi

Every year thousands of refugees are resettled to dozens of host countries. While there is growing evidence that the initial placement of refugee families profoundly affects their lifetime outcomes, there have been few attempts to optimize resettlement destinations. We integrate machine learning and integer optimization technologies into an innovative software tool that assists a resettlement agen

European emission legislation has in recent years put a strict limit on NOx emissionsfrom heavy-duty truck engines. EGR and selective catalytic reduction are the two mostcommon technologies applied in a modern heavy-duty diesel engine to fulfill the legislation.The scope of this thesis is to explore other ways of reducing NOx emissions emittedby a heavy-duty engine. Several technology options are

Lacking secure attachment representations is associated with vulnerability to mental and physical health problems, perhaps mediated by increased susceptibility to stress and impaired emotion regulation. Even though cognitive representations of self and others tend to favor confirmation over information, research has shown that adult attachment security can be positively influenced. In a randomized

OBJECTIVE: Small airway disease and chronic obstructive pulmonary disease are common in primary Sjögren's syndrome (pSS). However, the underlying inflammatory mechanisms behind pSS-associated airway disease have not been studied in detail. We therefore wanted to study cytokine and leucocyte levels in induced sputum in never-smoking patients with pSS.METHOD: Induced sputum cytokines and leucocytes

We study the intergenerational social mobility of women by looking at how migration was associated with socioeconomic marriage mobility using complete-count census data for Sweden. The censuses 1880–1900 have been linked at the individual level, enabling us to follow almost 100,000 women from their parental home to their new marital household. Marriage market imbalances were not an important push

Abstract: A side-by-side comparison of updated guidelines regarding contrast medium-induced acute kidney injury (CI-AKI) from the Swedish Society of Uroradiology (SSUR) and the European Society of Urogenital Radiology (ESUR) is presented. The major discrepancies include a higher glomerular filtration rate (GFR) threshold as a risk factor for CI-AKI and for discontinuation of metformin by SSUR, i.e

On the basis of a game-theoretic model, this paper argues that governments typically manage crises more effectively in systems where political power is concentrated in a single party, but they are more likely to make investments in future welfare in systems where political power is shared among several parties. The paper makes two contributions. First of all, it shows that both crisis-management f

This paper presents a polylithic framework of review and theory development (RTD) papers. Based upon a reflective analysis of review papers that I have written, read, and/or reviewed, I build a framework suggesting four types of RTD papers: organizing reviews, assessing reviews, specific-theorizing reviews, and broad-theorizing reviews. The four types vary according to the research focus and resea

Sweden's population doubled in size between 1750 and 1850 despite a century of stagnating per capita incomes and real wages, which has led many historians to attribute the population explosion to the introduction of the potato. This article provides the first systematic evidence on the potato's contribution to Swedish living standards and population growth. Potatoes at least doubled output per acr
