Semi natural grasslands increase bird diversity on crop fields During recent decades populations of farmland bird species have declined dramatically across Europe. The main cause of this decline has been established to be agricultural intensification. This intensification has led to a decrease in heterogeneity, i.e. habitat variation, in the agricultural landscape through increased field sizes, w

Blommor bland åkrar, inte så bra som man kan tro Sedan ett par år tillbaka kan man längs många åkerkanter se blomstrande planteringar. Dessa blomremsor är inte bara där för att det ser vackert ut utan är en del av åtgärder för att höja antalet vilda insekter och djur i åkerlandskap. Under flera årtionden har jordbruket ökat i stora delar av Europa. Det är både andelen mark som man odlar och hur

Barkgnag av kronvilt, effekt av utfodring? Kronvilt (Cervus elaphus) kan orsaka stora skador på Sveriges skogar genom barkgnagning, något som leder till stora ekonomiska förluster då träden drabbas av svampinfektioner, reducerad tillväxt, deformationer m.m. Det finns många faktorer som är viktiga för att förstå varför kronviltet gnager bark. Det handlar dels om trädkaraktärer så som tjocklek oc

Varför minskar antalet avkommor hos plattmasken M. lignano? Då hotet om den globala klimatförändringen blir större och större är det än viktigare för oss att förstå hur organismer kan påverkas av förändringar i deras miljö. För djur som lever i akvatiska miljöer kan en ökad nederbörd eller avdunstning av vatten leda till en förändring i saltkoncentration. För att många organismer ska överleva mås

Hur påverkas plattmaskar av saltkoncentrationer? Vår planet utsätts idag för stora, snabba och drastiska miljöförändringar då mänskligheten har bidragit till växthuseffekten. Eftersom förändringarna går så snabbt hinner inte alltid evolutionen med. Detta innebär att växter och djur inte hinner anpassa sig till sina nya hem. Vi ville studera en organism som idag naturligt och snabbt kan anpassa si

This thesis looks into the political discourse surrounding the doping scandal that has developed in Russian sport over the last two years. The paper hypothesizes that because of the importance of nationalism and Russia’s great power status, the Putin regime has, despite publicly stating the opposite, actively contributed to the further politicization of sport by returning to a sport discourse clos

Landscape fragmentation and habitat loss are detrimental to biodiversity, affecting highly specialised species the most. Species distribution models usually require either solid knowledge about the ecological niche of the species or spatial distribution data. Many endangered species have, how- ever, a relatively unexplored ecological niche in combination with a very small area of distribution. A m

Hunting a Gene That Makes Plants Green Photosynthesis is the process plants use to obtain energy from sunlight. In doing so, they produce oxygen and sugars, which supports life on earth as we know it. To harvest sunlight, plants use pigments know as chlorophylls, which also give plants their distinctive green color. Chlorophyll is a cyclic tetrapyrrole which is similar in structure to heme, the c

In this thesis I examine how young transgender respondents in the survey, " Folkhälsoenkät barn och unga i Skåne 2016 ” value their health and stress. A comparative quantitative analysis of cisgender and transgender respondents demonstrate that the transgender respondents, both binary and non binary, in general value their health less good than the cisgender respondents. A statistic analysis

Instance-level semantic segmentation refers to the task of assigning each pixel in an image an object class and an instance identity label. Due to its complexity, this problem has received little attention by the research community in the past. However, owing to the recent successes of deep learning technology, solving it suddenly seems possible. Starting from an initial pixel-level semantic segme

Since the inception of social media, an increasing number of studies have investigated how social media is used the local government level, particularly in light of its perceived democratic potential. Although studies have mainly focused on examining local governments’ social media communication, some research argue that it is the organisational structures and practices of local governments affect

The aim with this study is to analyse how social workers reason and understand that some youth who grew up in households living on social assistance is also in need of assistance as a young adult. This study contains qualitative interviews with seven social workers in Malmö. All respondents work in the field of social assistance. This study also investigates how social workers understand and perce

Akrylmonomerer i kombination med polyuretandispersioner skapar polyuretanmodifierade akrylatdispersioner, PUMAs. En PUMA är en typ av vattenbundet bindemedel som används i färg och lack. För att utvärdera hur de olika akrylaterna påverkar en PUMA, testades akrylat monomerer genom att svällas in i polyuretandispersioner. Egenskaperna hos en PUMA visade sig vara beroende på typ och mängd av akrylat.Acrylic monomers in combination with polyurethane dispersions form polyurethane modified acrylic dispersions, PUMA’s. A PUMA is a type of water borne binder used in lacquers and paints. To evaluate the effects different acrylic components have on a PUMA, swelling of acrylic monomers into polyurethane water dispersion was made for different acrylics. It showed that the properties of the PUMA can be

This thesis studies the choice of floatation method using a dataset based on 703 public offerings in Sweden between 2006 and 2017. A logistic model is utilised to study the determinants of underwriting, an ordinary least square model to estimate the direct cost of floatation, and the cost of underwriting is estimated using the Heckman sample selection model. The results are generally aligned with

As the boundaries between different communication disciplines blur, PR experts are forced to operate in increasingly competitive business environments. They are pressured to prove the usefulness of their activities in measurable terms. Evaluation techniques are key to this challenge as they have the potential to win over organisational decision makers and to help steer communication programmes ef

As a respond to the development of Internet and Digital technologies, EU listed creation of Digital Single Market (hereinafter referred to as: “DSM”) as a strategic goal. The development of DSM would contribute in securing competitiveness within the Union. Establishment of DSM inevitably raises an issue of data management in the EU and in order to successfully form DSM, EU needs to create a harmon

Explaining how social regulations of inclusion among raid-oriented guilds in World of Warcraft are regulated by code was the approach chosen for this thesis, as an attempt to take on the perspective of consensus. By looking for consensus rather than conflict, it was possible to detect possible indicators for social exclusion in the code of the in- game environment. Data on social norms was collec
