Dockless bike-sharing systems (DLBS) have gained much popularity due to their environmentally friendly features. This study puts forward a distinctive framework for assessing the environmental influences of DLBS in high resolution based on DLBS transaction data. The proposed framework firstly estimates the transport mode substituted by DLBS for each recorded bike-sharing trip by utilizing the rout
Climate warming has substantially advanced the timing of spring leaf-out of woody species at middle and high latitudes, albeit with large differences. Insights in the spatial variation of this climate warming response may therefore help to constrain future trends in leaf-out and its impact on energy, water and carbon balances at global scales. In this study, we used in situ phenology observations
The Ukrainian Shield and Voronezh Crystalline Massif constitute the Sarmatian segment of Baltica. Here, only a few mafic-ultramafic dykes and layered intrusions have been dated, recording early Statherian (ca. 1800–1750 Ma) ages. We have determined new U-Pb baddeleyite ages for the Novogol sill (1789 ± 2 Ma) and the Gremyachye intrusion (1781 ± 7 Ma), which fall within the previously established a
Sharing economy platforms have been transforming production and consumption systems in cities around the world. While the sharing economy may contribute to addressing sustainability issues, its actual economic, social and environmental impacts remain poorly understood. Advancing more sustainably promising forms of sharing and leveraging its benefits, while circumventing its pitfalls, is becoming i
During the earliest Triassic microbial mats flourished in the photic zones of marginal seas, generating widespread microbialites. It has been suggested that anoxic conditions in shallow marine environments, linked to the end-Permian mass extinction, limited mat-inhibiting metazoans allowing for this microbialite expansion. The presence of a diverse suite of proxies indicating oxygenated shallow se
Popular Abstract in Swedish Avhandlingen består av fem stycken artiklar som analyserar och estimerar finansiella prisprocesser. Alla artiklarna handlar också om stokastiska volatilitetsprocesser som estimeras med Bayesiansk statistik och Markov Chain Monte Carlo (MCMC) metoder. Det första pappret utvecklar en modell för att mäta den amerikanska och de regionala europeiska aktiemarknadernas påverThis dissertation consists of five papers concerned with the estimation and analysis of financial price processes. The first paper develops a stock price model and analyzes the impact of the US and the regional European stock markets on the local European countries’ stock markets. Among several things, we find that the dependencies among the stock markets do not increase during periods of distress
The productivity of agricultural and forest ecosystems in regions at higher latitudes is to a large extent governed by low temperature and moisture conditions. Environmental conditions are acting both above- and below-ground and regulating carbon fluxes and evapotranspiration. However, the understanding of various feedbacks between vegetation and environmental conditions is still unclear. In this
There has been much debate on the topic of whether stricter environmental regulations can promote environmental performance and economic performance at the same time. Different researchers have used different indicators to measure environmental performance and economic performance in their empirical studies. However, it is a surprise that few studies have checked the relationship between environme
Farnesyl pyrophosphate (FPP) is an intermediate in cholesterol biosynthesis, and it has also been reported to activate platelet LPA (lysophosphatidic acid) receptors. The aim of this study was to investigate the role of extracellular FPP in platelet aggregation. Human platelets were studied with light transmission aggregometry, flow cytometry and [35S]GTPγS binding assays. As shown previously, FPP
Säkerhetsrådet ska i enlighet med art. 39 FN-stadgan vidta kollektiva åtgärder för att bevara den internationella freden och säkerheten. Säkerhetsrådet kan inom ramen för detta uppdrag vidta militära och icke-militära åtgärder under stadgans kapitel VII. För att Säkerhetsrådet ska kunna agera krävs att de fem permanenta medlemmarna Frankrike, Kina, Ryssland (Sovjetunionen), Storbritannien och USA
There is an increasing shift of hope from international negotiations to local actors for promoting sustainability by ‘thinking globally while acting locally’. Municipalities are such carriers of hope, taking on increasing responsibility as implementers of sustainability. The problem is that sustainability is a social construction site, and implementing it means ‘making it up as you go’. With this
