Dagens samhälle står inför stora miljöproblem genom klimatförändringar. En stor bidragande faktor är utsläppen av växthusgaser som produktion av energi leder till. IT står för en stor del av världens energikonsumtion. Detta har lett till att teknologier och praxis har utvecklats för att minska IT:s miljöpåverkan, vilket kallas för grön IT. Ett antal studier har gjorts för att kart-lägga utsträckni
Background Low fill rates of goods transportation causes low overall utilization of resources in the logistics sector. The total goods flow is expected to increase and thus CO2-emissions. Rail freight is a low emission alternative to e.g. road haulage. To counter this development, initiatives have been aiming for achieving better efficiencies and promoting rail freight. Information sharing is cons
Betong har under lång tid varit ett av de vanligaste byggnadsmaterialen och används idag i stor utsträckning till framförallt bärande konstruktioner. En bärande konstruktion utsätts för olika typer av påfrestningar och en av de mer problematiska för betong är frostangrepp. Problematiken beror på betongens begränsade draghållfasthet och att vid låga temperaturer fryser vattnet i betongen till is. EConcrete has been one of the most common construction material for a long time and today it is used to a large extent in load-bearing structures. Load-bearing structures are exposed to different types of stresses and one of the most severe is frost damage. The problem with frost damage is due to the low tensile strength of concrete. When the water in concrete freezes at low temperatures the water
In recent years, crowdfunding has emerged as an alternative for entrepreneurs when raising external capital for their ventures. Funders within the crowdfunding context often face information asymmetry issues since it is difficult for them to measure the venture credibility based on the information and financial history presented during a crowdfunding campaign. Therefore, it becomes important for t
There is a consensus within both academia and politics on the important role of cities in achieving a more sustainable world, however, many scholars emphasise that the implementation of sustainable cities is often unsuccessful. The planning process from sustainability visions to actual implementation in an urban context is not straightforward or linear, and discursive struggles influence the proce
Hur människor rör sig genom staden till vardags spelar roll. Inte minst inom stadsplanering har fysisk mobilitet kommit att bli en viktig fråga, då denna sägs ha potential att motverka segregationsprocesser. Trots detta råder det brist på akademisk forskning inom området. Denna uppsats kombinerar ett intresse för hur mobilitet respektive den vita medelklassen påverkar städers socio-spatiala uppdelPeople’s everyday movements across the urban space matter. Indeed, for city planners looking to counter urban segregation processes, the issue of physical mobility is of prime concern as it bears the potential of overcoming ethnic and socio-economic divisions in the city. Yet, there is a lack of academic research matching this interest. In examining the role of mobility and the white middle-class
Inequality of Opportunity has recently emerged in the development agenda. The unequal access to opportunities can reinforce poverty and inequality traps. Conditional Cash Transfer (CCT) programs have consolidated as an important policy tool to fight against poverty. In addition, they have a great potential to equalize opportunities. The relationship between CCT programs and inequality of opportuni
Havet och vattnet symboliserar för mig avkoppling och rekreation, likväl som träning och sport. Att blicka ut över havet eller en vattenspegel får mig att känna ett lugn och välbefinnande. Det här examensarbetet tog sin början då jag ville undersöka ett aktuellt ämne. Jag fick till min kännedom att det flytande badhuset Liljeholmsbadet invid Bergsunds strand på Södermalm i Stockholm hade stängts
The study of post-translational modification has driven scientist to have a better understanding of protein function, activity and behavior in the metabolism that could later be useful for developing new drugs and treatments targeting key proteins in diseases, like cancer or neuronal disorders. In this project we tried to optimize the Acyl-Biotin Exhange of proteins coming from Chinese Hamster Ova
The sharing economy is currently widely discussed and politically of great importance, especially in urban areas. After a first rise in public interest due to a potential decrease of consumption, engaged actors are now calling for regulation mechanisms to defend the concept against the co-option by large incumbent firms, who transform the original idea into new economic opportunities. The accommod
Den ökade sjukfrånvaron på grund av psykiska besvär har givits allt större uppmärksamhet i samhället, vilket väckte ett intresse av att studera fenomenet ytterligare. Detta genom att se till vilken inverkan psykosociala arbetsmiljöfaktorer kan innebära för effektiviteten och kvaliteten i arbetet. Syftet med föreliggande studie är att, utifrån såväl ett ledar- som medarbetarperspektiv, undersöka de
The academic field of followership is, in relation to leadership, considerably unexplored. Numerous academic subfields and theories have emerged within the school, the most influential being a four frame model developed by Robert E. Kelley. The model divides followers on the two dimensions active and critical thinking, into five categories: Sheep, alienated, pragmatist, yes-people and effective fo
Erosion av vattendrags flodbottnar och intilliggande strandmiljö är ett stort samhällsproblem som förväntas öka i takt med framtida klimatförändringar. Statens geotekniska institut (SGI) har erhållit anslag för att kartlägga större vattendrag i Sverige med hänseende på risken för skred i framtiden till följd av klimatförändringar. Ett vattendrags sårbarhet för erosion kan bedömas utifrån ett indexErosion of river basins and adjacent bank environment is a major environmental problem that is expected to increase in the future due to climate change. The Swedish geotechnical institute (SGI) has been granted funding by the Swedish government for mapping major rivers in Sweden with regard to the risk of landslides due to climate change. A river's vulnerability to erosion can be assessed base
Bakgrund: En journalgranskningsstudie av Sveriges kommuner och landsting gjord 2013–2015 visade att vårdskador kostar Sverige 7 miljarder/år. Vårdskador är ett globalt problem. WHO har därför utvecklat olika instrument och riktlinjer för att öka patientsäkerheten på operation. Operationsverksamhet är en högriskmiljö och anestesisjuksköterskans vardag. Syfte: Syftet med studien var att undersöka oc
Extant research within the entrepreneurial marketing field has typically focused on the migration away from traditional marketing concepts while mostly ignoring the inclusion of branding as a fundamental principle of marketing. This paper is specifically interested in the often overlooked element of a young firm’s ability (or lack thereof) to control its brand and brand identity as perceived by it
Based on a qualitative approach, this study examines and problematizes how employees in a flexible organization, through the internal communication community, consolidate and renegotiate the organization's identity. Furthermore, it creates an understanding of the flexible employees ability to co-create, and their view on the importance of being able to identify themselves with the organization
The PID controller is by far the most popular controller for process control in industry today [Åström and Murray, 2008]. The combination of its relatively simple usage and its satisfactory results within several areas has gained its popularity [Visioli, 2006]. However, the tuning of the controller is crucial. An automatic tuning method was developed by [Åström and Hägglund, 1984] in the mid-eight
Thesis purpose: The aims of this thesis are to investigate (1) the effect of sponsorship disclosure timing (before vs. after) on attitudes towards the brand and attitudes towards the vlogger in a beauty vlog context and (2) test a possible moderating effect of discount codes on the relationships between disclosure timing and attitudes towards the brand and the vlogger. These two aims were pursued
The Nigerian economy grew at an average rate of 7% between 20002011. However, recent drop in oil prices has led to calls for economic diversification away from oil. Using the services-led growth theoretical framework, this thesis provides an overview of the Nigerian service-sector. Through an analysis of descriptive statistics, the thesis showed that services have been contributing significantly t
