The main aim of this paper is to study land-atmosphere exchange of carbon dioxide (CO2) for semi-arid savanna ecosystems of the Sahel region and its response to climatic and environmental change. A subsidiary aim is to study and quantify the seasonal dynamics in light use efficiency (epsilon) being a key variable in scaling carbon fluxes from ground observations using earth observation data.

Popular Abstract in Swedish När man hör ordet ”klimatförändringar” tänker många direkt på en förhöjd temperatur – så kallad global uppvärmning. Även om en förhöjd temperatur är en viktig del av framtida klimatförändringar så är det inte den enda förändringen vi kan förvänta oss. Sjöar på norra halvklotet och således även i Sverige har under de senaste årtiondena fått en ökad vattenfärg. Orsaken baThe effects of increasing temperatures, in light of climate change, have been a well-studied topic during the past decades. However, aquatic ecosystems are also faced with additional challenges such as increasing water colour, known as “brownification”. Although we know that temperature and water colour will increase simultaneously this has been given little attention in ecological research. In th
Det digitala samhällets utmaningar för EU:s upphovsrättsliga system är många. Med syftet att implementera WIPO:s internettraktater från 1996, samt att horisontellt harmonisera regelverket för upphovsrätt och närliggande rättigheter, antog EU år 2001 det mycket kritiserade InfoSoc-direktivet. Dess mest kontroversiella delar rör upphovsrättsundantagen samt det specifika skyddet som ges till tekniskaThe challenges of the digital networked environment to the EU copyright system are many. With the task of implementing the 1996 WIPO Internet Treaties while at the same time horizontally harmonizing the legal framework on copyright and related rights, the EU in 2001 adopted the much-criticized InfoSoc Directive. Its most controversial provisions were on copyright exceptions and the specific protec

Lentic water bodies (lakes and reservoirs) offer favorable conditions for silica (SiO2) burial in sediments. Recent global estimates suggest that (1) lentic SiO2 trapping is a globally important SiO2 flux, and (2) through reservoir construction, humans have dramatically altered river dissolved SiO2 (DSi) transport and coastal DSi delivery. However, regional to global scale patterns and controls of
The private sector plays a more and more important role in securing the progress of infrastructure development. Private sector participation is believed to guarantee more efficiency in the supply of infrastructure services and cut down the cost of this supply. Project finance through the BOT model is an internationally well-recognised method to handle large infrastructure projects. The project met
Aim: To investigate the problem of IT-users and IT-developers and their different abilities to use IT and communicate by means of IT, caused by differences in the background of the two categories, their knowledge and experience. Also to investigate what this problem may lead to when developing IT-related services and products. Method/material: Ten semi-structured interviews of about ten hours all
I denna avhandling står släktinghemsföräldrar i fokus och stor vikt har lagts vidderas erfarenheter av att ta hand om ett släktingbarn, något som sällanuppmärksammas i forskning kring släktingplacering. Det övergripande syftet med studien har varit att utifrån ett livsloppsperspektiv och med familjeteoretiska begrepp analysera vad det kan innebära att ta hand om en familjemedlems barn genom ett foThis dissertation focuses on kinship foster parents and their experiences caring for their kinship children, something that is rarely touched on in kinship care research. The primary purpose of this study is to, based on a life-course perspective and with family theoretical concepts, analyze what it might mean to take care of a family member’s child through a formal commitment such as a foster car

This dissertation about the utilization of applied social science is based on studies of research use in three different policy sectors - the social service, the building, and the working life sectors. In these studies some characteristics of the different policy sectors, like the distribution and exercise of power and control, was found to play a fundamental role in forming the patterns of resear
Denna avhandling undersöker 1998 års svenska förbud mot sexköp utifrån den uppmärksamhet lagen fått som ett unikt tillvägagångssätt för att reglera prostitution, den starkt polariserade politiska miljö den existerar inom och de många juridiska motsägelser den uppvisar. Genom material insamlat genom en multisituerad metod mellan åren 2009 och 2019 visar studien att sexköpsförbudet är en variant av This essay thesis examines Sweden’s 1999 ban on purchasing sexual services, considering the attention it received as an unprecedented approach to governing prostitution, the highly polarised political environment in which it exists, and the multiple legal contradictions it displays. Using material gathered through a multisited method from 2009 through 2019, the study shows that the offence is a va
Background: International migration has been on the rise over the past few decades and is expected to remain high. Young people make up a significant proportion of those migrating. It has long been known that young people are at greater risk of sexual violence and there is growing evidence that migrants too, are particularly vulnerable. There is a lack of evidence on young migrants’ vulnerability
Anthropogenic changes to the environment expose wildlife to many pollutants. Among these, tropospheric ozone is of global concern and a highly potent pro-oxidant. In addition, human activities include several other implications for wildlife, e.g., changed food availability and changed distribution of pathogens in cities. These co-occurring habitat changes may interact, thereby modulating the physi

Popular Abstract in Swedish Det finns två etablerade sätt att beskriva zigenarnas historia i Sverige. Historien talar antingen om hur illa myndigheterna burit sig åt mot zigenare, eller så berättar historien om zigenarnas självvalda isolering. Gemensamt för beskrivningarna är påståendet att zigenare alltid varit desamma och uppvisar ett likartat levnadssätt genom historien. I denna avhandling studThis thesis analyses Swedish gypsy policy between 1880 and 1970, as part of a larger sociopolitical project undertaken by the Swedish authorities to promote social order and stability. During this period, the treatment of marginalized groups was shaped by the same visions and objectives as for the population as a whole. Gypsies in Sweden have been subject to the same regulations for as other poor

With more and more digital collections of various information resources becoming available, also increasing is the challenge of assigning subject index terms and classes from quality knowledge organization systems. While the ultimate purpose is to understand the value of automatically produced Dewey Decimal Classification (DDC) classes for Swedish digital collections, the paper aims to evaluate th
Spatial downscaling is an effective way to obtain precipitation with sufficient spatial details. The performance of downscaling is typically determined by the empirical statistical relationships between precipitation and the used auxiliary variables. In this study, we conducted a comprehensive comparison of five empirical statistical methods for spatial downscaling of GPM IMERG V06B monthly and an
