Reviews and syntheses : Changing ecosystem influences on soil thermal regimes in northern high-latitude permafrost regions

Soils in Arctic and boreal ecosystems store twice as much carbon as the atmosphere, a portion of which may be released as high-latitude soils warm. Some of the uncertainty in the timing and magnitude of the permafrost-climate feedback stems from complex interactions between ecosystem properties and soil thermal dynamics. Terrestrial ecosystems fundamentally regulate the response of permafrost to c

The risk of clinically diagnosed gout by serum urate levels : Results from 30 years follow-up of the Malmö preventive project cohort in southern Sweden

Background: Hyperuricemia (HU) is in the causal pathway for developing clinical gout. There are few population-based assessments of the absolute and relative risk of clinically diagnosed incident gout in subjects with HU. We aimed to explore the long-term risk of developing incident gout among asymptomatic adults with different levels of serum urate (SU). Methods: Malmö Preventive Project was a po

Clash of civilizations demystified

This paper provides empirical evidence in support of the clash-of-civilizations view on the nature of interstate conflicts in the post-Cold War era. First, we show that countries belonging to different civilizations have a higher probability of interstate conflict before and after the Cold War period, but not during the Cold War. Second, we explain the differential impact of civilizations on confl

Ethnic minorities and trade: The Soviet Union as a natural experiment

This paper examines the role of ethnic minorities in bilateral trade between countries of the ex‐Soviet Union. We argue that both forced re‐settlement of entire ethnic groups during the Stalin era and artificially drawn borders in Central Asia led to an exogenous ethnic composition within countries. Using data collected by ethnologists on the share of ethnic groups across countries, we build an in

War and well-being in transition: Evidence from two natural experiments

This paper assesses the effect of the Russo–Georgian conflict of 2008 and the Ukrainian–Russian conflict of 2014 on the well-being of minorities in Russia. Using the Russian Longitudinal Monitoring Survey (RLMS), we find that the well-being of Georgians in Russia suffered negatively from the 2008 Russo–Georgian conflict. We show that the conflict has no direct effect on the labor market outcomes o

Genetic distance, trade, and the diffusion of development

The determinants of countries' long‐term income differences feature prominently in the literature. Spolaore and Wacziarg (The diffusion of development, Quarterly Journal of Economics, 2009, 124, 469–529) argue that cultural differences, measured by countries' genetic distance, are an important barrier to the diffusion of development from the world's technological frontier. We revisit their finding

Clash of civilizations and the impact of cultural differences on trade

This paper studies the Clash of Civilizations hypothesis from an economic perspective. Using data on bilateral trade and measures of culture, we evaluate how the impact of cultural differences on trade evolves over time during and after the Cold War. Evidence suggests that the negative influence of cultural differences on trade is more prominent in the post-Cold War era than during the Cold War. F

United Agents : Community of Practice within Border Policing in the Baltic Sea Area

De senaste årens fokus på säkerhetsrisker i samhället har gett upphov till olika former av polisarbete, såsom gränsöverskridande och underrättelsebaserat polisarbete. Den här studien uppmärksammar ett samverkansprojekt mellan gränsmyndigheter i Östersjöområdet som pågick mellan 2014 och 2015. Projektet fick namnet Turnstone och involverade underrättelsepoliser, gränspoliser och kustbevakare från SThe risks and insecurities emphasised in contemporary societies have given rise to diverse forms of policing, such as transnational and intelligence-based police collaborations. This dissertation focuses on a border police collaboration project, called Turnstone, that took place between 2014 and 2015, aiming to address issues related to irregular migration and cross border crimes in the Baltic Sea

Least Squares and Maximum Likelihood Estimation of Mixed Spectra

In this paper, we propose a novel 1-D spectralestimator for signals with mixed spectra. The proposed methodis partly based on the recently introduced smooth spectralestimator LIMES, in which the smoothness is accounted for byassuming linearity within predefined segments of the spectrum.The proposed method utilizes this formulation but also allowssegments to change size to better estimate the spect

The Matched Window Reassignment

In this paper we calculate reassigned spectrogramsusing the envelope of an arbitrary signal as matched window. Weshow that the matched window then give the perfectly localizedreassignment for any time-translated and frequency-modulatedtransient signal with corresponding envelope. The general expressions of the corresponding scaled reassignment vectors arederived and the matched window reassignment

Bioenergetic bypass using cell-permeable succinate, but not methylene blue, attenuates metformin-induced lactate production

BACKGROUND: Metformin is the most common pharmacological treatment for type 2 diabetes. It is considered safe but has been associated with the development of lactic acidosis under circumstances where plasma concentrations exceed therapeutic levels. Metformin-induced lactic acidosis has been linked to the drug's toxic effect on mitochondrial function. Current treatment strategies aim to remove the

Is the eye-movement field confused about fixations and saccades? : A survey among 124 researchers

Eye movements have been extensively studied in a wide range of research fields. While new methods such as mobile eye tracking and eye tracking in virtual/augmented realities are emerging quickly, the eye-movement terminology has scarcely been revised. We assert that this may cause confusion about two of the main concepts: fixations and saccades. In this study, we assessed the definitions of fixati

Accelerating Graphics in the Simics Full-System Simulator

Virtual platforms provide benefits to developers in terms of a more rapid development cycle since development may begin before next-generation hardware is available. However, there is a distinct lack of graphics virtualization in industry-grade virtual platforms, leading to performance issues that may reduce the benefits virtual platforms otherwise have over execution on actual hardware.
