Statistical upscaling of ecosystem CO2 fluxes across the terrestrial tundra and boreal domain: Regional patterns and uncertainties
2021
The regional variability in tundra and boreal carbon dioxide (CO2) fluxes can be high, complicating efforts to quantify sink-source patterns across the entire region. Statistical models are increasingly used to predict (i.e., upscale) CO2 fluxes across large spatial domains, but the reliability of different modeling techniques, each with different specifications and assumptions, has not been assessed in detail. Here, we compile eddy covariance and chamber measurements of annual and growing season CO2 fluxes of gross primary productivity (GPP), ecosystem respiration (ER), and net ecosystem exchange (NEE) during 1990–2015 from 148 terrestrial high-latitude (i.e., tundra and boreal) sites to a…
Tieteen sensurointiyritykset ja tutkijoiden itsesensuuri uhkaavat akateemista vapautta
2023
Tunnen tukijoita, jotka ovat hylänneet herkullisen tutkimusaiheen, koska heitä on pelottanut, että he joutuisivat kiistanalaisen aiheen tutkimisen takia vihamielisten tahojen tikun nokkaan. Heitäkin enemmän tunnen tutkijoita, jotka eivät suostu haastateltaviksi mediassa tai jotka eivät puhu julkisissa tilaisuuksissa tutkimuksensa tuloksista heihin kohdistuvien hyökkäysten pelossa. nonPeerReviewed
Consumo de drogas y Sida
2002
El consumo de drogas intravenoso (CDI), por compartir materiales no estériles de inyección ha estado muy asociado a la difusión de la infección por VIH y el desarrollo del SIDA desde el inicio de la epidemia, fundamentalmente en los países del sur de Europa y de forma especial en España y algunos años más tarde en Portugal. En la actualidad países del Este del continente presentan una afectación creciente, como por ejemplo Ucrania, y el CDI constituye una forma principal de transmisión en casi todas las zonas del mundo. La gran afectación de España muestra una evolución desigual entre las comunidades autónomas, ya que mientras algunas, como Madrid o el País Vasco, presentan altas tasas de S…
Poliittisia tunteita häpeästä inhoon ja vihaan
2018
Monitieteinen konferenssi poliittisista emootioista iski suoraan ajan hermoon. Kansainvälinen joukko huippututkijoita nosti esiin päivänpolttavat kysymykset äärioikeiston, populismin ja misogynian uudesta noususta länsimaisessa politiikassa ja analysoi näiden ilmiöiden taustalla vaikuttavia tunteita. Samalla otettiin askeleita filosofisen ja empiirisen tutkimuksen vuoropuhelun edistämiseksi. nonPeerReviewed
Ibuprofen degradation using a Co-doped carbon matrix derived from peat as a peroxymonosulphate activator
2021
The wider presence of pharmaceuticals and personal care products in nature is a major cause for concern in society. Among pharmaceuticals, the anti-inflammatory drug ibuprofen has commonly been found in aquatic and soil environments. We produced a Co-doped carbon matrix (Co-P 850) through the carbonization of Co2+ saturated peat and used it as a peroxymonosulphate activator to aid ibuprofen degradation. The properties of Co-P 850 were analysed using field emission scanning electron microscopy, energy filtered transmission electron microscopy and X-ray photoelectron spectroscopy. The characterization results showed that Co/Fe oxides were generated and tightly embedded into the carbon matrix …
How different policy instruments affect green product innovation : A differentiated perspective
2018
Based on representative firm-level data for the three countries Austria, Germany, and Switzerland, we investigate the effects of energy-related regulations, taxes, voluntary agreements, and subsidies on the creation of green energy products, and analyze through which channels policy affects green product innovation and which factors mediate the observed effects. Policy may affect green product innovation by directly stimulating the supply of green products/services, or more indirectly by stimulating the demand for green products/services. Our data set allows us to distinguish between the two channels, which improves our understanding of the frequently observed positive net effect of policie…

Financial system in steering the economy towards planetary well-being
2024
This chapter discusses the possible roles that financial system may play in steering economic production towards planetary well-being. The costs associated with using natural resources are seldom equal to the actual environmental costs incurred. The present chapter proposes linking Sir Partha Dasgupta’s Impact Equation and the standard asset pricing framework and discusses the roles that financial institutions and central banks as well as debt and equity funding play in supporting production that preserve planetary well-being via the incentives of those in need for and those willing to supply funding. It is proposed that the increasing costs of capital and the financial exclusion of non-env…

Production of ethyl lactate by activated carbon-supported Sn and Zn oxide catalysts utilizing lignocellulosic side streams
2021
In this study, activated carbon-supported Sn and Zn oxide catalysts were prepared from hydrolysis lignin and used for the conversion of model solutions of trioses, hexoses, and lignocellulosic biomass hydrolysates to ethyl lactate. Both catalysts, SnO2@AC and ZnO@AC, were able to produce ethyl lactate in high yields. SnO2@AC was a more active and selective catalyst in triose (dihydroxyacetone) conversion, providing 99% yield to ethyl lactate. ZnO@AC, by contrast, was more selective in glucose and hydrolysate conversion, with a yield of 60% and 85%, respectively. The ethyl lactate yields were significantly higher than those from the optimized model solution experiments when using ZnO@AC cata…
