The extensive studies on D. sechellia have made it a familiar example of chemosen-sory evolution and speciation. This specialist drosphilid species is well-known for its ability to tolerate and actively seek out its toxic host Morinda citrifolia (noni). It was originally thought that this toxic fruit was the exclusive host of D. sechellia because most drosophilids cannot tolerate and are deterred
Denna studie syftar till att undersöka hur en organisation kan upprätthålla en viss föreställning genom strategisk kommunikation. Detta uppnås genom det empiriska exemplet mjölk, ett livsmedel som under lång tid framställts som objektivt, naturligt och vetenskapligt, vilket lett till en etablerad föreställning om att mjölk är nödvändig i vår dagliga kost. Syftet uppfylls genom en foucauldiansk kriThis thesis aims to investigate how an organization can maintain a certain conception through strategic communication. This is achieved by the empirical example of milk, a food that is looked upon as something objective, natural and scientific, which has led to an established conception that milk is essential in our daily diet. The purpose of the thesis is met by a foucauldian critical discourse a
This study explores the plausibility of the thesis that the thematisation of issues re-lated to data protection is affected by the degree to which an issue can be experi-enced personally. In drawing a line from issues management theory to agenda-setting and the theory of news value, this study demonstrates that knowledge about thematisation struc-tures is central to issues management and that pre
Material och produkter som kan innehålla hälsofarliga ämnen förekommer på förskolor i Hässleholms kommun. Bristande kunskap och rutiner bidrar även till barns exponering för dessa ämnen. Det är av vikt att man arbetar långsiktigt för giftfria förskolor. Åtgärder finns, och en hel del kan göras omgående för att minimera problemet. Användningen av kemikalier har ökat markant de senaste decennierna.During the last decades the production and consumption of chemicals has increased dramatically. We know that some chemicals are hazardous for humans and the environment but for most of them our knowledge is limited. Children are very sensitive to hazardous substances compared to adults because of their undeveloped bodies and different behavior. Due to lacking knowledge and regulation of chemicals
The massive rural-urban population flow has been proceeding in China for decades ever since the 1980s. Millions of labor migrants move to industrialized cities for a better future for themselves, as well as their families. The increasing amount of migrants has led to the phenomenon of the “left-behind”. Among the left-behind group, left-behind children seem to be at a relatively vulnerable situati
Large-scale mining has been declared to be a central development strategy of Colombia which has caused the emergence of resistance movements of peasant, ethno-territorial and indigenous groups. This study analyses the concept of resistance in the framework of the Afro-Colombian community of the river Yurumanguí. This community has managed to keep its territory free from externally driven mining an
Syftet med studien var att genom en kvalitativ ansats få en djupare förståelse av och ökad kunskap om hur vuxna patienter som tillfrisknat från en ätstörning uppfattade och förhöll sig till sin sjukdom och tillfrisknandeprocess. Som metod användes tematisk analys och tio teman identifierades. Åtta kvinnor som tillfrisknat från diagnoserna Anorexia Nervosa, (AN) Bulimia Nervosa (BN) eller ÄtstörninThe purpose of the study was, through a qualitative approach, to get a deeper understanding and greater knowledge of how adult patients, who have recovered from an eating disorder, perceived and reacted to their illness and recovery process. The chosen method was thematic analysis and ten themes were identified. Eight women, who had recovered from the diagnoses of anorexia nervosa (AN) or bulimia
The aim of this master’s thesis is to provide an analysis of the student housing market in Lund, which actors can use as a base to work on the problematic situation, in order to provide a more just student housing situation in the future. For that purpose four interviews were conducted with the most important actors on the student housing market in Lund. This thesis first examines the characterist
Mikrotexturer är mikrometerstora avtryck på kvartskornens ytor samt på korn med andra mineralogiska egenskaper. Kvartskorn, som förekommer i de flesta sedimentära miljöer, innehåller mikrotexturer som undersöks särskilt på grund av kvartsmineralets unika mineralogiska egenskaper som möjliggör bevarandet av mikrotexturer genom olika miljöer. I denna studien är mikrotexturer en viktig källa för att Microtextures are micrometer-sized imprints on the surfaces of quartz grains and on grains with other mineralogical compositions. Quartz grains, which occur in most sedimentary environments, contain microtextures which are especially studied due to quartz unique mineralogical properties allowing for preservation of microtex-tures through different environments. In this study, microtextures are an
Visionaries around the world are advocating for a shorter working week, and there is a reason behind it. Long working hours have been shown to impede productivity while a reduction in working hours increases work-life balance. Future generations’ economic and environmental sustainability may furthermore benefit from a shorter working week. Through a redistribution of working hours, equality and em
The present quantitative research focuses on studying the effect of uncertainty in online information search related mainly to travel planning. The main emphasis is in the individual and combined effect of these variables towards different demographic segments of international travelers. In order to do so it draws insights from Uncertainty avoidance (Hofstede, 2001) and information foraging theory
This master thesis contains an overview of existing additive manufacturing methods and considers possible new methods. The purpose being to develop a method for additive manufacturing that can create 3D objects with composite material and/or out of metal. Further this method should work on a low cost additive manufacturing machine. A development process is used in order to select an appropriate me
This research is a theoretical contribution to CCT and existing literature on ownership, investigating whether ownership has become an out-dated ideal in consumer culture. We explore how Millennials negotiate issues of ownership and sharing in the context of collaborative consumption. Consequently, the study provides insights on new consumption forms, and more specifically swapping and access-base
In surveillance applications one thing to consider is how much of a scene one can cover with a camera. One way to augment this is to take images with overlap and blend them, creating a new image with bigger field of view and thereby increase the scene coverage. In this thesis work we have been looking at how one can create panorama images with a pan-tilt-camera and how fast it can be done. We chos
We study the predictability of sentiment on stock return of the Hong Kong market. We measure sentiment by forming composite sentiment indices from several proxies using principal component analysis and the partial least square method. We find that sentiment measures using either method have similar in-sample forecasting power but the one formed by using partial least square method has better out-o
The aim of this study was to get a deeper understanding of how Unit Heads within the Swedish social services view the work environment of social workers in social welfare offices. The study was based on six social services Unit Heads from the southern part of Sweden. Semi structured interviews were used to examine what different factors affect the social workers in social welfare offices work envi
Medelpensioneringsåldern i Sverige har länge varit mer eller mindre konstant trots att medellivslängden har ökat. Syftet med denna studie är att undersöka huruvida det finns en optimal pensionsålder när den förväntade återstående livslängden är en annan än den Pensionsmyndigheten förutsatt och om detta kan förklara den konstanta medelpensioneringsåldern. Studien tillämpar en kvantitativ metod och
Idag använder sig en majoritet av alla svenska grund- och gymnasieskolor av en lärplattform. En lärplattform är mjukvara som stödjer både det administrativa och pedagogiska arbetet och används bland annat till kommunikation, bedömning och till att tillhandahålla material i undervisningen. Uppsatsen kopplar samman lärares upplevelser av dessa lärplattformar till teorier gällande användaracceptans.
