Att utveckla kollektivtrafiken är ett viktigt steg för att uppnå de klimatmål Sverige har åtagit sig att följa. Ett verktyg i utformningen och kapacitetsutvecklingen av hållplatserna är trafiksimulering. Detta arbete utforskar hur hållplatser kan på bästa sätt modelleras och kalibreras för fotgängare i programmet Vissim som är en simuleringsmjukvara utvecklad av företaget PTV Group. Vid kalibreriThe development of public transport is an important step toward reaching the climate goals Sweden has set. Traffic simulation is an instrument when developing and designing public transport stops. This thesis investigates how public transport stops can be modeled and calibrated for pedestrians in the PTV groups software Vissim. During the calibration, the platform was divided into four different z

Bakgrund: Diabetes typ 2 är en kronisk folksjukdom som ökar över hela världen till följd av övervikt och fetma. Sjukdomen innebär att kroppen producerar mindre insulin och inte längre klarar av att hantera glukos i blodet. Den primära behandlingen vid diagnosen är egenvård i form av ändrade levnadsvanor. Diagnosen kan leda till svåra komplikationer samt kortare liv om personer med diabetes typ 2 m

Social commerce (s-commerce) is a new paradigm for electronic commerce (e- commerce) where sociability, such as reviews and forums, is introduced into the e-commerce context. Previous research point to s-commerce design as a topic that needs more research, and that creating user-centered s-commerce websites is cumbersome and a hindrance for s-commerce adoption. The main research objective of this

The purpose of this dissertation is to examine how design-related copying is described on Diet Prada’s Instagram account and how their activity is received in the fashion press. Further on, the aim is to examine the discourses concerning the relationship between a copy and an original that can be discerned in the Diet Prada-debate. There is existing research on the effects of design-related copyin

Audiovisual content is heavily prevalent in many modern societies. Film, in particular, is a favourite form of entertainment to many. Film is by nature both multimodal and polysemiotic, employing the modalities of visual and auditive as well as the semiotic systems of language, gesture, depiction and music. Some audiences do not have immediate access to content using either the auditive or visual

Changes in the agricultural landscape have caused declines in bumblebee species richness and abundance. Semi-natural grasslands are key habitats for bumblebees in agricultural landscapes, and therefore it is important to understand which habitat characteristics promote species-rich bumblebee assemblages in these habitats. In this study, I investigate the importance of trees within semi-natural gra

Alpha-synuclein is a protein involved in several neurodegenerative diseases, such as Parkinson’s, where it has been observed to form amyloid fibrils or Lewy bodies. However, how or to what extent alpha-synuclein is involved is not known. I have in this thesis been conducting experiments in order to design an experimental model system to study how alpha-synuclein interacts with a cell membrane. Thi

Risk communication is recognised as an essential component of crisis preparedness, enabling people at risk to take informed decisions to protect themselves. Research has shown that foreign-born people including refugees and immigrants to a lesser extent than others are reached by the information and are less prepared for crisis, making them particularly vulnerable in crisis situations. Employing a

The interest of religion in the academia of history and the history of ideas has held an unobtrusive and modest position during modernity. Often, religion and its influences, was regarded as something waning, something that was about to disappear. Instead science would become the foremost guiding light upon which most historians would focus their gaze. This essay aims to examine how article-author

he most important factor in a creative mind, is the confidence in that you can create. When I talk to people about music and creativity, many often reject the top- ic or excuse themselves by explaining that “They cannot play the piano...?”, “they aren’t good at reading notes...!” or that “they just simply aren’t the creative person!”. Peo- ple are afraid of failure and of being judged by other

Great salt lakes around the world are drying at a rapid rate. The drying salt lakes gives rise to several health and socio-economic concerns for the population in the surrounding region. The respective governments undertook various measures to address the concerns relating to the drying of salt lakes. This research aims to assess the strategies towards increasing the water level of saltwater lakes

Abstrakt Bakgrund: Psykisk ohälsa är ett av de snabbast växande hoten mot folkhälsan varav depression och ångestsjukdomar ökar mest. Forskning visar att kostvanor har ett samband med psykisk ohälsa. Distriktssköterskan möter patienter med psykisk ohälsa i sitt arbete och hälsoprevention ingår som en del i arbetet. Syftet: Syftet var att undersöka kostens betydelse för psykisk ohälsa genom att kar

Climate change and human impact play a huge role in the sustainability and development of ecosystems and the services they offer to societies over temporal and spatial scales. Fossil pollen-based estimates provide unique information on past land cover change, but to date there are not many methods able to create spatially continuous maps and have a fine scale of land cover changes inferred from po

Impoliteness has been considered as a marginal phenomenon for scientific research for some time, although as a type of behaviour it has always been around us. The field of impoliteness studies is currently growing, but there are clear gaps in the research that concerns the conventionality of expressions, different semiotic systems through which impoliteness is expressed and cross-cultural comparis

Nitrogen dioxide (NO2) is an important air pollutant with both environmental and epidemiological effects. The main aim of this thesis is to explore spatial patterns and temporal trends of tropospheric NO2 concentrations globally using data from the OMI instrument aboard NASA’s Aura spacecraft. Additional aims are to validate the satellite data by comparing it to ground-based measurements, and to f

EU har antagit mål att till år 2030 minska koldioxidutsläppen med 40%, Sverige har gått steget längre och beslutat att år 2045 ska nettoutsläppen av koldioxid i landet vara noll. Av världens totala utsläpp står betongtillverkningen för 7% vilket innebär att det är ett område med stor potential till förbättring. Syftet med det här examensarbetet är att bidra med kunskapsutveckling kring återanvändThe EU has established a binding target to reduce CO2 emissions by 40% by 2030, Sweden has taken one step further and has decided to be carbon neutral by 2045. 7 % of the world´s total CO2 emissions comes from concrete production which makes it a field with great potential to improvement. The purpose of this study was to evaluate the requirements for reusing concrete elements in practice in the c

Sedan efterkrigstiden har det skett en markant ökning av antalet anmälda brott. Detta har inneburit att arbetsbelastningen på de rättsvårdande myndigheterna ökat. En konsekvens av utvecklingen är att lagstiftaren försökt effektivisera processen samt hitta andra sätt att avgöra ansvarsfrågan på. Som följd av detta har bland annat åtalsunderlåtelseinstitutet fått en etablerad plats inom svensk strafSince the post-war era, there has been a significant increase in the number of crimes being reported. This has led to increased workloads for law enforcement authorities. As a direct consequence of this development, legislators have sought to streamline processes and to find alternative means of issuing determinations on matters of guilt and responsibility. As a result, the institute of abstention

På grund av en växande befolkning av unga och gamla, och nyanlända medborgare de senaste åren har välfärdssektorn expanderat till att innefatta fler. Det leder i sin tur till ett större arbetskraftsbehov och kompetensförsörjningsbehov för att försörja och finansiera välfärdssektorn. Samtidigt står flera arbetsvilliga individer utanför arbetsmarknaden. För att fortsätta behålla vår välfärd måste vi
