Parabens are a group of commonly used conservatives in cosmetics, foods and pharmasuticals. Although they have been widely used since the 1920s the effects of these substances are still not thoroughly understood. This literature review aims to enlighten the prevailing discussion regarding chemical safety using the precautionary principle. During the last decade a vast amount of research has been d
De senaste åren har det skett en stor omsättning av högre kommunala chefer. En del kan förklaras med pensionsavgångar, men en del har med något annat att göra. Tidigare undersökningar och forskning pekar på att vi har en kommunal tjänstemannaorganisation och politik i förändring, där trycket har ökat på både politiker och tjänstemän. En av riktningarna går mot en ökad politisk professionalisering
Climate change poses a current and ongoing threat to urban areas worldwide. Rising sea levels and the increased occurrence of heatwaves, heavy rainfall and related impacts due to erosion and landslides in particular are risks that are becoming increasingly urgent to address in the near future. Though Sweden is seen as a pioneer in sustainable city development, climate change adaptation is a relati
I enlighet med att vårt samhälle digitaliseras, kommer även skolan att vända sig åt en mer digital värld. Sverige driver en offensiv kamp mot att digitalisera undervisningen, vilket visar sig bland annat i läroplanen Lgr11 där IT ska löpa som en röd tråd i alla ämnen. Trots detta har vi författare sett en tendens till att de tekniska verktygen finns i klassrummen men inte används fullt ut. Lärarna
We investigate investor heterogeneity between private, institutional, commercial, government and foreign investor in the Swedish market. OLS-estimation using dividend yield and term spread as regressors reveal no clear results. VAR-analysis to investigate lead-follow relationships between investor groups indicate that foreign follows private and commercial investors, though the result is problemat
Denna uppsats handlar om hur distansarbetssättet via smartphone, Office Home Smartphone, påverkar balansen mellan det privata och det arbetsrelaterade livet. Här presenteras denna balans som Work Life Balance, även kallat WLB; vad det är, hur man uppnår det och om det är någonting att sträva efter. Även det ovannämnda arbetssättet Office Home Smartphone, även kallat OHS, presenteras; vad det ä
Organic polymer-based solar cells recently attracted much attention as an efficient and inexpensive light-to-electricity conversion solution. However, the mechanism behind charge generation processes in organic materials is still not fully understood due to complex nature of carbon-based compounds. Studies of charge generation, recombination and transport processes are essential for revealing the
Technological innovations within the field of sustainable energy production require a substantial amount of capital investment in order to conduct research and development. Crowdsourcing represents an innovative and new approach to raising the capital investment needed for sustainable technological innovations in the sustainable energy sector and is inherently entrenched with Transition Theory.

Abstract When a dung beetle has arrived at a dung pat, it soon starts to form a ball, which it will later roll away in a straight line. Rolling in a straight line ensures that the beetle will never risk rolling back to the fierce competition at the pat, thus eliminating the chance of getting its ball stolen by others. Before rolling out from the pat, the beetle performs an orientation dance on to
Aluminium alloys are used in a wide range of applications due to their high tensile strength concomitant with low density. Additionally, aluminium alloys form a naturally occurring and passivating oxide layer, which leads to high corrosion and weathering resistance. In industrial manufacturing, aluminium alloys acquire their desired properties through specially designed heating processes. A common
Young people, who previously have been placed away from home in foster care, are from the political perspective, a particularly vulnerable group. This is a very general manner that previously placed young people live or has lived more volatile and turbulent, with changing within education and very poor self-management, What these peoples experience when they enter the independent adulthood is an a
Previous research has mainly addressed the impact of over/under-education on wages in developed countries. Therefore, this paper attempts to fill the void gap in the literature by empirically examining the impact of over-education and under-education on wages in a developing country, namely Egypt, using the 2012 Egyptian Labor Market Panel Survey (ELMPS). In order to do so, actual years of educati
The ambition of this thesis was to provide Scania with a program that can calculate power losses in hypoid gears from gear teeth mesh using the programming language Python. The program should be able to calculate power losses on different points on the gear flank to help designers and engineers in the development face of a new axle gear. Because of governmental requirement and costumers’ wish to m
Thesis purpose: The purpose of this study is to examine what factors moderates or influence the entrepreneurial orientation. Our study provides a unique context that was examined. Argued by theory, moderators vary according to different contexts. Subsequently, we want to confirm some of the moderators discussed in literature and research what other context specific moderators that exist. Furthermo
When the international monetary system was on the gold standard, China was the only country adhered to the silver standard. Silver functioned as currency in China but acted as commodity in international markets. Its price experienced downturn trend from 57 cents per ounce in January 1929 to 23.38 ounces per ounce in January 1933. Then it increased to 75 cents per ounce in May 1935. Dramatic fluctu
Bakgrund. Den äldre befolkningen i Sverige förväntas öka framöver vilket innebär mer arbete för hemtjänsten. Detta tillsammans med ökade kostnader har ställt ett oerhört tryck på hemtjänsten. Med be- gränsade resurser och höga prestationskrav ställs hemtjänsten inför en stor utmaning för att kunna ta hand om landets åldrande befolkning. Datorisering kan få en avgörande roll för att verksamheten sk
