Borta bra eller hemma bäst? : Ålderns påverkan på platsuppfattningen mellan Alperna och Svenska fjällen

We travel more to day than we have ever done before and there is an abundance of destinations to choose from. All -destinations have vantages and disadvantages and the things that are favourable for one traveller can be the opposite for another. So the questions are, why do we have different opinions about the same destination and what is it that makes us choose one destination before another?The purpose with this thesis is to investigate if the demographic factor age has an influence on the Swedish traveller?s opinion about winter destinations. The thesis also investigates if there is a link between the traveller?s demography and their opinion of a destination.

Våga surfa längre än vad radiovågorna tar er : En undersökning om P4 Kalmars Facebook-sida och dess medlemmar

The rise of social media has created an endless source of possibilities for companies to interact and connect with their target audiences. As it is a new channel, companies may experience uncertainty on how to use it to its fullest potential.The purpose of this study is to describe how the Public Service radio channel, P4 Kalmar, use its Facebook page and how its members perceive the communication on this platform. We have also presented recommendations on how P4 Kalmar can improve the relationship with its members. To reach our conclusions we have combined theoretical references with a quantitative content analyze, a survey and qualitative depth interviews.By analyzing our findings we came to the conclusion that P4 Kalmar have to develop a strategy for communicating on social media. But since no general communication strategy for the organization exists they have to develop one before developing one for social media.

VINDKRAFTSETABLERINGAR : EN JÄMFÖRANDE STUDIE OM NÄRBOENDES INSTÄLLNING TILL VINDKRAFT OCH VINDKRAFTSETABLERINGAR I SVERIGE OCH BRASILIEN

To achieve a sustainable development, three aspects have to take equal place in the society; environmental, economical and social. To reduce the impact on the environment and the amount of greenhouse gases supplied to the atmosphere, industrialized countries and less developed countries must start cooperating. Also the use of renewable energy sources, like solar, hydro and wind power, have to increase.Wind power has great potential as a future energy supply. It is cost efficient, quickly developed and the resource is abundant and available worldwide.Examinations made in Sweden, indicates that there are difficulties establishing wind power at the same pace as the environmental goals, set by the Swedish government, requires. Mainly because people living nearby potential areas for wind power farms, appeal against the decision.This study aims to investigate differences between how people in Sweden and Brazil look at wind power as a future energy source and at the establishing process.

Män i tights och kvinnor i byxor : En kritisk undersökning av hur film kan användas i historieundervisningen för att lära eleverna studera förändringar i genus och hur dessa kan relateras till sin samtidskontext

Film is a tool frequently used by teachers, but it is often limited to showing students how historical time periods looked like, or as a way for students to search for historical inaccuracies. The aim of this essay is to study whether it is possible to use two films based on the legend of Robin Hood as a way to teach students how to contextualize gender history. Through the use of film analysis and gender analysis of two different versions of Robin Hood, The adventures of Robin Hood and Robin Hood: Prince of thieves were analyzed. The study has shown that it is indeed possible to use film as a source material for the study of gender history, and that film can tell us a lot about the contemporary view of gender, masculinity and femininity. The didactical analysis concluded that there was no theoretical objection of using film as a source material; however, there are some things that a teacher should be aware of. Although film may be a good way to create a varied study environment and benefit students with reading- and writing disabilities, there is a risk that time-constraints and lack of knowledge of film and its methodology on, behalf of both teachers and students, may make it hard to implement.

?Det sade bara klick?: en studie om 15-åriga tjejers Internetanvändning utifrån ett källkritiskt perspektiv

This Masters thesis aims at investigating how 15-year old girls use the Internet, particularly on their free time, taking a source critical perspective. It includes group interviews. The main question of this thesis was whether there is a need for specific user education. The following four questions were asked: What do they do on the Internet during their free time? In what way do the girls learn how to interact with each other on the Internet? How do they relate to different types of web pages and materials from a source critical aspect? What content do they consider to be relevant in a user education? The study is mainly focused on information use and information behaviour in different contexts.

Att bryta isoleringen - sociala faktorer i nätbaserad distansutbildning

Detta projekt fokuserar på distansstudenter och deras studiesituation i tre nätbaserade kurser. Genom en empirisk studie bestående av samtal med studenter och lärare, samt deltagande observation, har vi försökt finna lösningar för att förbättra studenternas lärandemiljö. De sociala faktorerna visade sig vara av stor betydelse i en studieform som tidigare kännetecknats av isolation mellan studenter och lärare. Projektet visar på hur en nätbaserad utbildningsplattform genom enkla tekniska lösningar kan ta hänsyn till studentens behov i fråga om att stödja kommunikation och samarbete..

Ingenting är sant, allt är tillåtet : En kvalitativ studie om historiska datorspel som Assassin?s Creeds påverkan för det oavsiktliga lärandet och dess pedagogiska möjligheter

The main purpose of this study is to investigate the unintentional learning that happens during the use of computer games. With the use of interviews with students in the ages 13-15 who all have played the game series Assassin?s Creed, and then compared them with students who does not play the game, we have been able to identify that some learning is taking place, but that the student?s attitude towards the subject, and their maturity, also is vital for the learning. Even tough, the students who didn?t really enjoy history as a subject showed better knowledge after playing the game, than the students who hadn?t played at all, which indicates that computer games can be a good source for learning.

Energieffektivisering i ett verkstadsföretag : En analys av energibesparande åtgärder samt uppvärmnings- och kylsystems driftkostnader och koldioxidutsläpp

The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.

Revisionsplikten : Förändringen av revisorernas yrkesutövning sedan revisionsplikten avskaffades

The thesis is based on a case study of a Swedish discussion forum where survivalism and prepping is the main focus. The awareness of an abrupt and immanent breakdown together with a full and thorough preparation for any conceivable threat posed by that breakdown is what legitimizes survivalism and prepping. This preparation, or risk-proofing is 1) grounded in an isolation of the body and its predispositions from perceived risks, and 2) actualized through artefacts, theoretical and practical knowledge and awareness. Stories of the embodied survivalist are also stories of masculine and heterosexual subjects and ?the others?.

Storjuktan ? Rekonstruktion av ett sekels kvicksilverbelastning. : En undersökning av kvicksilverkoncentrationer i daterat bottensediment.

The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.

Antibiotic resistance associated with bacteria in irrigation water : a case study of irrigation ponds in Southern Sweden

The focus of this project was to characterize the occurrence of ESBL-­?producing bacteria in two irrigation water ponds in Southern Sweden. Samples were taken from two ponds nearby each other, from which analyses were made based on levels of community and individual isolates. Community samples were used for attempts for characterization of resistance patterns in irrigation water using the Omnilog PM-­?plate system. The growth of community microbiota in the presence of the following antibiotic substances was assessed; amikacin, gentamicin, kanamycin, penicillin G, ampicillin, piperacillin, trimethoprim, potassium tellurite and ciprofloxacin. Isolates were pure cultured using semi-­?selective media: LB, Rainbow Agar, mEnterococcus, 0.1 TSA and VRBD. A total of 177 isolates were isolated randomly. Each isolate was identified using the Omnilog GENIII-­?system of biochemical characterization. Further, the isolates were tested on Brilliance ESBL-­?agar for their ability to grow. Out of the total number of isolates, 30 were selected, preferably Enterobacteriaceae or Pseudomonas spp., based on their high similarity to library strain during the identification in the Omnilog-­?system. These were further characterized using Etest-­?sticks. Three selected strains were picked for further analyses using exogenous isolation for attempts to simulate horizontal gene transfer, and Omnilog PM-­?panels containing various antibiotics of interest. Selections of samples were chosen for molecular tests targeting plasmid-­?borne resistance genes CTX-­?M1, CTX-­?M2 and SHV. The method for assessing community-­?resistance patterns showed ambiguous data that was difficult to interpret; further optimization is recommended. For all tested PM-­?plates, generally greatest differences between substances were found among wells with the strongest concentration of antibiotic substance. A total of 175 isolates displayed ability to grow on ESBL-­?agar. Etests confirmed ability of isolates to resist many ?-­?lactam antibiotics and many were clinically resistant to certain substances. No plasmids were transferred during exogenous isolation. During molecular tests, a few matches were found for the CTX-­?M1 gene. Isolates analyzed with Omnilog PM-­?plates showed resistance to most compounds tested. The isolates showed greatest resistance toward penicillin G, ampicillin, amikacin, kanamycin and trimethoprim. In the study, it was established that resistance among bacteria was frequently occurring in the irrigation water, and ?-­?lactamase producing bacteria was very common. Extended studies are needed to assess the frequency-­? and occurrence of horizontal gene transfer (HGF) in this environment. Although some potential corresponding data is found, it is at this point not possible to determine whether the resistances are due to antibiotics used in veterinary medicine, human medicine or one additional reason is travel and trade. in irrigation water using the Omnilog PM-­?plate system.
