Vem hjälper andra – och när? Denna studie undersökte situationsbaserade och individbaserade faktorers påverkan på hjälpbeteende. Studien bestod av en enkät om personlighetsdrag och världsbild samt en fiktiv annons för en välgörenhetsorganisation som delades ut till de 130 deltagarna. Annonsen utformades i två versioner, där hälften av deltagarna fick en version som spelade på en positiv känsla (waWho helps others – and when? This study examined situation based and individual based factors’ impact on helping behaviors. The study consisted of a survey about personality traits and worldview, and a fictive ad from a charity organization, which were handed out to 130 participants. The ad was designed in two versions, where half of the participants were assigned a version which simulated a posit

Postpartum depression (PPD) affects about 13% of all women giving birth and is described as a devastating disorder. Yet, the majority of women suffering from PPD do not seek professional help. Insecure attachment is shown to be a significant help-seeking barrier for women with PPD; however as research thus far has focused on help-seeking populations it is still unknown how different attachment sty

Utifrån socialpsykologiska och postkoloniala perspektiv var syftet med studien att undersöka hur självbilden hos en grupp unga tjejer som gjordes till avvikande i den svenska kontexten påverkades av skolan och medias blick på dem. Målet var att undersöka hur intervjupersonernas självbild påverkades av rasifiering, hur de förstod sina erfarenheter av rasism och vilka strategier de använde för att sThe aim of this study was, based on social psychological and postcolonial perspectives, to examine how the self-image of a group of young girls that were constructed as deviant in the Swedish context were affected by the school’s and media’s view of them. The purpose was to examine how the self-image was affected by racialization, how experiences of racism were understood and which strategies the

Kreativitet är idag ett vanligt förekommande ord i organisatoriska sammanhang. Genom att skapa ett kreativt organisationsklimat kan det gynna såväl medarbetares hälsa som företags möjligheter att skapa nya lösningar. Vi vill att fler organisationer ska ge medarbetarna utrymme till att vara kreativa då det föreslås ha positiva effekter på den stigande psykiska ohälsan i Sverige. Syftet med denna st

En ökande efterfrågan på lägre bränsleförbrukning ökar kraven på totalverkningsgraden i lastbilar. Då effektiviteten hos en modern dieselmotor är ungefär 40 % produceras stora mängder spillvärme. Återvinning av denna spillvärme kan göras med termoelektriska generatorer. Spänningen och den inre resistansen hos dessa generatorer är dock temperaturberoende, vilket resulterar i olika optimala strömmarIncreasing demand for lower fuel consumption increases the importance of a higher total energy efficiency in trucks. Since the efficiency of a modern diesel engine is in the range of 40 %, large amounts of waste heat are produced. Recovering this energy can be done with thermoelectric generators. However, these generators’ open load voltage and internal resistance are temperature dependant, which

In times of increased environmental awareness, there exists a desire to not only build new environmentally friendly and renewable power generating units, but also to increase the efficiency of all existing technology. Wind power is such a renewable and environmentally friendly technology. Wind turbines and wind power have made giant leaps in the world in the past years, with an almost exponential

Wind energy has been used by mankind since ancient times and the last decades have seen large technological advancements in the field of wind turbines. One technology, although not very common, for harnessing the energy in the wind is the vertical axis wind turbine (VAWT). These types of turbines have not been as successful as the horizantal axes wind turbines (HAWTs) regarding efficiency and comm

PV power production is becoming more and more common and one can easily imagine that a so called boom is near in southern Sweden. As the distribution grids are designed for power flow out to the households, and not the other way around, the question is what will happen that sunny day when the households in a neighborhood produce more electricity than they consume. This master thesis project was ca

In today’s housing market, open house plans are requested increasingly. This puts a demand on the beams being used to manage longer spans and is therefore exposed to larger loads. To manage these larger loads, one solution is to increase the beam dimensions. Because of demands to fulfill standardized measurements for doors, ceiling heights and roofing heights, there is not always room for the beam

Studiens syfte var att studera hur medarbetare förhåller sig till organisationsförändringar och vilken betydelse sådana förändringar har för den egna arbetsrelaterade identitetsutvecklingen. Semistrukturerade intervjuer genomfördes med fem medarbetare från fem olika organisationer med erfarenhet av att genomgå förändringar. Intervjumaterialet analyserades med tematisk analys, vilket resulterade i The aim of this study was to explore co-workers’ approach to organizational change and the meaning of those changes related to their own work-related identity development. Semi-structured interviews were conducted with five co-workers from five different organizations who had experienced major organizational change. Thematic analysis was used to analyze the data, and six main themes were identifie

Loans play an important part in how individuals fulfill their goals in the Swedish society. It makes it possible for people to buy a house or get an education, things that might have been impossible without the possibility of taking a loan. A loan also comes with obligations and restrictions on the loan takers life, paying off a loan can take a lifetime and it requires that the loan taker become s

Smart grids have been proposed as a way to increase grid robustness and reduce consumption peaks and at the same time decrease electricity costs for the end users. This thesis aims to develop generic models for smart grids focusing on smart houses which are used to test if it is possible to reduce consumption peaks, decrease electricity cost and at the same time increase grid stability. Models hav

Electrical machines in electrical vehicles are sometimes put under a lot of stress when for example climbing an uphill road. In order for the machine to cope with the heat generation that comes of running extended periods of time near or at peak power one needs a highly developed cooling system. At the division of Industrial Electrical Engineering and Automation (IEA), located at Lunds Tekniska Hö

Abstract Future climate change scenarios project a water temperature increase of 2 to 5 ˚C for the upcoming 100 years. Simultaneously, north temperate zones will face precipitation changes that will ultimately enhance humic content and water colour in freshwater systems. I hypothesised that increased temperature and water colour would benefit the grazing activity of mixotrophs, and the dominance

Som ett steg i utvecklingen av nästa generations hjullastare görs studier av olika delsystem för att se var energiförbrukningen ligger. Denna masteruppsats har som mål att ta reda på energiförbrukningen för fyra länkage med olika konstruktion. Den kommer även att undersöka hur energiförbrukningen förändras när en elektro-hydraulisk kompensering introduceras för att hålla lasten parallell samt vad As a stage in the development of the next generation of wheel loaders, all systems are evaluated in order to minimize the energy consumption. This master thesis aims to investigate the energy consumption for four linkages with different design. It will also investigate how the energy consumption changes when an electro-hydraulic compensation is added in order to keep the load parallel and what the
