Error estimation and data fusion are critical to improving the accuracy of global model- and satellite-based precipitation products for practical applications. However, they face challenges over vast areas of the world due to limited ground observations. Triple collocation (TC) method can overcome this limitation and provide an efficient way for error estimation without the “ground truth” and thus
Past efforts to synthesize and quantify the magnitude and change in carbon dioxide (CO2) fluxes in terrestrial ecosystems across the rapidly warming Arctic-boreal zone (ABZ) have provided valuable information but were limited in their geographical and temporal coverage. Furthermore, these efforts have been based on data aggregated over varying time periods, often with only minimal site ancillary d
The aim of this thesis is to analyze whether the aggressive foreign policy actions recently taken by the Kingdom of Saudi Arabia can be understood and explained through political identity theory and role conception theory from a social constructivist theory perspective. This will be done through a discursive analysis method according to Laclau and Mouffe, aiming to identify a discourse of the iden
Permafrost extends 40% of the Qinghai-Tibet Plateau (QTP), a region which contains the headwaters of numerous major rivers in Asia. As an aquiclude, permafrost substantially controls surface runoff and its hydraulic connection with groundwater. The freeze–thaw cycle in the active layer significantly impacts soil water movement direction, velocity, storage capacity, and hydraulic conductivity. Unde
Monitoring ecosystems at regional or continental scales is paramount for biodiversity conservation, climate change mitigation, and sustainable land management. Effective monitoring requires satellite imagery with both high spatial resolution and high temporal resolution. However, there is currently no single, freely available data source that fulfills these needs. A seamless fusion of data from th
Linking individual and stand-level dynamics during forest development reveals a scaling relationship between mean tree size and tree density in forest stands, which integrates forest structure and function. However, the nature of this so-called scaling law and its variation across broad spatial scales remain unquantified, and its linkage with forest demographic processes and carbon dynamics remain
Empowerment has been a key conceptual underpinning of participatory health research (PHR), both as a set of processes that inform how partners and diverse stakeholders engage with each other, as well as a set of outcomes that contribute to improved health and social equity. The concept of empowerment is present in a number of characteristics of PHR as described in Position Paper No. 1 of the ICPHR
Place branding is defined as “the development of brands for geographic locationswith the aim of triggering positive associations about the area and distinguishinga place from other places” (Stevens et al., 2020, p. 752). Like all occupations,place branding is organised by discourses, or talk, that determine best practices andnorms about what constitutes expertise (Loacker and Sullivan, 2016). Expl
Polarimetric radar observations of deep convective storms frequently reveal columnar enhancements of differential reflectivity Z(DR). Such "Z(DR) columns" can extend upward more than 3 km above the environmental 0 C level, indicative of supercooled liquid drops being lofted by the updraft. Previous observational and modeling studies of Z(DR) columns are reviewed. To address remaining questions, th
Dagens signalregelverk ställer krav på en minsta längd för reserverat spåravsnitt bortom slutpunkt för rörelseväg till ett annat fordon i rörelse. Detta kallas för skyddsavstånd och krav som ställs på dess längd gör det möjligt att tillåta samtidiga rörelser på en driftplats vilken har positivt påverkan på kapaciteten. Skyddsavstånd kan i vissa fall anses vara för restriktiv och kapacitetssänThe current signalling regulations require a minimum length of reserved track beyond the end point of the train’s path to another moving vehicle. This is known as safety overlap and the requirement for its length allows simultaneous train movements to be permitted at the station which has a positive impact on capacity. Length requirements may in some cases be considered too restrictive and ca
In the 1940s, Swedish Nobel laureate Gunnar Myrdal noted a disconnect between the American creed (liberty and justice for all, equality) and the status of African-Americans (marginalization, disenfranchisement, segregation). Decades later, a similar disconnect is currently reflected in Myrdal's Sweden. The state of health for ethnic and racial minority migrants clashes with Swedish policy dict
A sediment sequence from a small forest lake in southwestern Sweden was investigated to explore the effects of forestry and land-use on catchment erosion and delivery of organic and minerogenic matter to the lake. Catchment-scale vegetation changes during the last 1,100 years were reconstructed quantitatively at 50-year resolution using pollen analysis and the Landscape reconstruction algorithm (L
Communication and collaboration is a major challenge for large-scale software development. Cognitive and psychological distance between individuals and teams affect this collaboration and can cause communications gaps. We propose a novel method for assessing distance between teams, and explore potential explanations for these distances. In an exploratory case study of the quality assurance departm
During the last glacial period Northern Hemisphere climate was characterized by extreme and abrupt climate changes, so-called Dansgaard-Oeschger (DO) events. Most clearly observed as temperature changes in Greenland ice-core records, their climatic imprint was geographically widespread. However, the temporal relation between DO events in Greenland and other regions is uncertain due to the chronolo
Treatments of emissions of primary biological aerosol particles (PBAP) were implemented in the global Earth System model EC-Earth. These emission schemes were improved to account for the strong peaks of PBAP concentrations in connection to precipitation events, which has been measured recently. The model is now able to treat the emission of bacteria, spores and pollen in dependency of precipitatio
Malaria is a public health problem which affects developing countries world-wide. Inadequate skilled lab technicians in remote areas of developing countries result in untimely diagnosis of malaria parasites making it hard for effective control of the disease in highly endemic areas. The development of remote systems that can provide fast, accurate and timely diagnosis is thus a necessary innovatio
Intensification of arable crop production degrades soil health and production potential through loss of soil organic carbon. This, potentially, reduces agriculture's resilience to climate change and thus food security. Furthermore, the expected increase in frequency of adverse and extreme weather events due to climate change are likely to affect crop yields differently, depending on when in the gr
Understanding 3d human interactions is fundamental for fine grained scene analysis and behavioural modeling. However, most of the existing models focus on analyzing a single person in isolation, and those who process several people focus largely on resolving multi-person data association, rather than inferring interactions. This may lead to incorrect, lifeless 3d estimates, that miss the subtle hu
Plants release to the atmosphere reactive gases, so-called volatile organic compounds (VOCs). The release of VOCs from vegetation is temperature-dependent and controlled by vegetation composition because different plant species release a distinct blend of VOCs. We used modelling approaches on ecosystem VOC release data collected across the Arctic, which is experiencing both rapid warming and veget
This paper is based on work from the Global Research, Innovation, and Education on Assistive Technology (GREAT) Summit that was coordinated by WHO’s Global Cooperation on Assistive Technology (GATE). The purpose of this paper is to describe the needs and opportunities embedded in the assistive product lifecycle as well as issues relating to the various stages of assistive product mobilization worl
