LIDAR-analys av flygsanddyner i Västerbottens inland : Har dynmorfologi bildad under tidigare interstadialer bevarats i landskapet?

The aim of this study was to map the prevalence of aeolian sand dunes in Västerbotten, northern Sweden to find dunes formed during earlier deglaciation phases, which was then preserved in cold-based conditions during the youngest stadial of the Weichselian glaciation. These preserved dunes were expected to be covered by a layer of till and have a rather faint morphology compared to dunes formed during the Holocene. Consequently, high resolution LIDAR-derived images from the Swedish mapping, cadastral and land registration authority (Lantmäteriet) was used to detect the dunes throughout an area covering most of Västerbotten, above the highest coastline and below the mountain range. The analysis resulted in several new findings of aeolian dunes compared to the findings in the quaternary soil map created by the Geological Survey of Sweden. Despite the fact some of the dunes at the LIDAR-derived image had a strange faint appearance, it was quickly evident during the fieldwork that the aeolian sand was not covered by till on any of the dunes visited.

Antal anställda på arbetsplatsen och attityder till invandrare : Sambandet mellan attityder till invandrare, arbetsplatsstorlek och individuella faktorer

Previous research shows that small workplaces more often discriminate immigrants during the process of hiring new employees than larger workplaces, and usually explains this result by referring to structural factors. At the same time, previous research also shows that self-employees tend to have different personality traits than other people. Could it be the case that the higher discrimination among small workplaces can be explained at an individual level? I examined the hypothesis through OLS-regressions using a survey called Employment, Material Resources, and Political Preferences. The results showed that people working at small workplaces tend to have more negative attitudes towards immigrants than people working at larger workplaces.

Hur påverkar energi- och proteinrik kost intaget av energi och makronutrienter?

Today 70 percent of the people residing in nursing homes are undernourished. One way to avoid that an individual is affected by malnutrition it is a necessity that the meals is customized after special needs current among other things as energy and protein. Food record is a method that can be used to examine and evaluate if an individual is getting sufficient nutrition and energy to cover the daily needs. For those suffering from malnutrition it is recommended to eat energy and protein enriched diet.AimsThe aim is to compare the intake of energy and macronutrients in a group of elderly people living in a nursing home in southern Sweden before and after the introduction of an energy and protein enriched diet based on newly developed recipes.MethodsFood record was made during four days. Food record means that everything that is consumed by an individual is noted precisely.

Fasta driftställen på internet : Ett koncept på (juridiskt) lös grund?

The purpose of this essay is to examine and compare the news covering of Swedens three biggest cities (the metropolitan areas) and their surrounding areas with the covering of the rest of the country (the provincial areas) in two daily national newspapers, Aftonbladet and Dagens Nyheter. The aim has been to answer the following questions:- What amount of the news coverage in Aftonbladet and Dagens Nyheter concern the metropolitan areas compared to the provincial areas, and how do these two newspapers differ in the news covering of these areas?- Is there a difference in the news articles size and content, depending on weather they concern the metropolitan or the provincial areas?- How has the balance between news concerning metropolitan and provincial areas changed over the recent 20 years?The theories used in this study are News values, the media commercialization and Popular Journalism, and The Agenda Setting Theory. The method that has been used is a Quantitative Content Analysis.Despite the essays hypothesis, that the news coverage in the two newspapers would be dominated by material from the metropolitan areas, the result showed that a majority of the examined articles concern the provincial areas. It also showed that Aftonbladet has a bigger percentage of provincial news than Dagens Nyheter.

Planteringsförbandets inverkan på bildningen av kärnved hos tall (Pinus sylvestris L.) : en modellsimulering av planteringsförbandets inverkan?

The current state of knowledge indicates that there is more than one factor that initiates heartwood transition. This study supports its hypothesis on the theory that heartwood is formed by a fixed fraction of the annual growthring, 0,5 to 0,8 rings. To calculate heartwood volume modelings were carried out in four different pine stands with different spacings, 0,75, 1,25, 1,5 and three meters. The model indicates heartwood diameter (HWD) and is based on four explanatory variables, height (H), crown ratio (CR%), diameter breast height (DBH) and tree height (TH). The shifting plant spacing results in varying growth rate in the juvenile stage.

Beror KRAV-grisars ledanmärkningar på miljöfaktorer?

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

Progesteronrelaterad diabetes mellitus hos älghund :

Diabetes mellitus (DM) is a relatively common endocrine disease in dogs and is more common in certain breeds than others, e.g. Nordic spitz breeds. Within the Swedish and Norwegian Elkhound population, female dogs are almost exclusively affected. The hypothesis in this study is that Swedish- and Norwegian Elkhounds develop DM during the progesterone phase of estrous (diestrous or pregnancy). Medical records from 51 female dogs of the breeds Swedish and Norwegian Elkhound were studied.

Den informella kommunikationens betydelse för de anställdas välbefinnande på Tetra Pak Packaging Material AB på Tetra Pak i Lund

Work is an important part of the lives of humans, fulfilling several functions; it establishes possibilities to interaction and to feeling as belonging to a context, it gives structure to time and space, creates common goals and it leads to a general well-being in individuals. For the well-being of employees it is essential with recuperation in a pleasant environment where you under relaxing and informal forms have a chance to interact with colleagues. The aim of this study was to investigate to which extent the employees of Tetra Pak Packaging Material AB at Tetra Pak in Lund experience that the informal communication during the coffee-break contributes to their well-being. The aim was also to distinguish if this potential well-being effects how the employees experience how work in general makes them feel. The hypothesis of the study is that the coffee-break effects the well-being in a positive way, and that it has a positive effect on how work in general makes the employees feel.

Visualisering av basalcellscancer med Tissue Viability Imaging - ett icke-invasivt diagnostiskt alternativ

Basal cell carcinoma (BCC) is the most common non-melanoma skin cancer. It can be divided in different subtypes. The most common type is superficial and is most frequently occurring on the trunk and on the face. In severe cases it can be difficult to differentiate basal cell carcinoma from other skin tumors, therefore a skin biopsy is conclusive diagnostic method. In terms of treatment, curettage is a common non-surgical treatment of basal cell carcinoma.

Påverkar det ekonomiska läget noteringarnas aktiekursutveckling? : En kvantitativ studie av noterade bolag på NASDAQ OMX Stockholm 2000-2010

Inledning: Inom finansmarknaden där en handelsplats för värdepapper finns är IPO ett omtalat ämne. Fascinationen ligger vid introduktionen av ett företag på börsen som tidigare varit privatägd och dess avkastning på aktien. Vidare är prissättningen på aktierna och timingen för en notering intressanta aspekter som har studerats sedan många år tillbaka. I denna uppsats ska det undersökas hur aktiepriserna för de noterade bolag har utvecklats vid olika ekonomiska tillväxter.Syfte: Syftet är att undersöka om det ekonomiska läget påverkar aktiekursernas utfall vid en notering samt hur dessa utvecklas på noteringsdagen och 30 dagar efter noteringen.Metod: Genom beräkningar av introduktionspriserna i jämförelse med stängningskurserna på noteringsdagen och 30 dagar efter noteringen får man fram aktiekursernas utveckling.Teoretisk referensram: Den effektiva marknadshypotesen och signalteorinResultat: Undersökningens resultat visade på att skillnaden i aktiernas avkastning mellan företag som noterat sig under en hög respektive låg ekonomisk tillväxt var mycket liten. Företagen som hade noterat sig under en hög ekonomisk tillväxt hade endast 0,1 % högre avkastning än de företag som noterade sig under en låg ekonomisk tillväxt.

Feeding preferences and foraging in Larvae of Manduca sexta and Spodoptera littoralis : a laboratory study based on olfaction

Larvae of Lepidopteran Manduca sexta and Spodoptera littoralis are pests of economical importance in several horticultural and agricultural crops. Knowledge of insect feeding preferences and behavior is crucial in order to find economically and ecologically sustainable solutions to the problems caused by these herbivores. The aim of this thesis was to study the behavior and the induced feeding preferences in larvae of M. sexta and S. littoralis when reared on certain host plants. The hypothesis was that larvae of M. sexta would have an innate preference for plants of the Solanaceae family and therefore discriminate the previously experienced nonhost when faced with the choice between a true host and the previous food source.

Inkluderande ?garskap i varierande demokratiska kontexter: En j?mf?rande fallstudie av svenskt utvecklingssamarbete med Rwanda och Tanzania

This thesis investigates how recipient countries' domestic type of democracy affects its inclusive ownership in international development cooperation. This is done by examining Swedish development cooperation with Rwanda and Tanzania during the period from 2010 to 2014, a time when ownership - a concept which emphasizes recipient countries' leadership over its own development - was a central part of the international development agenda. The two cases were selected through a most similar case design where the value of potential explanatory variables was similar, except for the recipient countries' types of democracy. Furthermore, the case study uses a comparative analysis to analyze strategies and reports done by SIDA and the Swedish Ministry of Foreign Affairs. Previous research focuses on the exclusion that national ownership can result in, in undemocratic national contexts. The main argument for this should be seen as the fact that ownership can not be representative if the power of the recipient's development agenda is limited to a decision-making elite.

Effect of Bacillus mediated priming on different natural genetic variants of Arabidopsis thaliana

In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

Entreprenörskap ? Vår tids skolpolitiska filosofi? En ideologikritisk analys av Lpf 94 och Skola 2011

The aim of this Master?s thesis is to examine the ideological currents that have influenced the swedish school system since the 1990's. The background of my interest is the lively debate in schools and media about the new School reform 2011. My hypothesis is that education in 2011 largely will be influenced by neoliberal and neoconservative values. The method I`ve used is discourse and ideology critique, which examines the relationship between rhetoric and power. These concepts are useful to explain the ideological change in different policy documents and in curricula, for example Lpf 94 and School 2001. The theoretical framework is based primarily on the neoliberal and the neoconservative agenda, which are two distinct political rationalities in the contemporary postmodern world.

Promotionsarbete med unga i förorten : - En kvalitativ fallstudie av RGRA, Rörelsen gatans röst & ansikte

This studie explores how a promotive youth movement that aims to activate adolescents in economically and socially exposed areas, can affect the youth?s participation in society and oppose their experience of stigmatization. The youth movement, whom is being studied, uses urban art expressions as a mean to engage and motivate the adolescents. The empirism has mostly been collected by a limited participatory observation, and through qualitative interviews with staff and adolescents in the movement. The result has been analyzed through Pierre Bourdieus field theory.
