Stress och alkoholbruk : En studie om manliga och kvinnliga chefer på en socialförvaltning i Skåne
Occupational stress and the use of alcohol to reduce stress are both separately common in our society. A few researchers have combined the two factors.The aim of this essay was to obtain an increased understanding of how male and female managers estimate their alcohol habits in relation to their occupational stress.We have interviewed nine managers who work at a social services department in Scania. Our main theories were the theory of psychosocial work environment of Lazarus, Karaseks demand/control model, epidemiology- and cultural perspective.Our results were;· Psychosocial work environment contributes to if the interviewed people experienced stress at work.· The grade of control has great influence if the interviewed people experience stress.· There weren't any correlation between stress and increased consumption of alcohol..
A cost benefit analysis of public procurement of pork meat : imported, Swedish or locally produced?
Public procurement stands for a substantial part of the total food consumption in Sweden. The majority of the procured food is today imported and according to market trends it?s intended to stay that way. Imported food is favoured for locally produced due to price pressure. Consequently domestic pork farmers have declined by 25 percent during the last twenty years.
Realtidsutvärdering av personbilsdata ur miljöperspektiv
This project examined the possibility to create an electronical aid with the purpose of increasing environmental awareness and to design the aid in a fashion that inspires other to develop similar applications. The impact of car traffic was examined, and the base of the aid was built up in modular form to simplify the hardware aspect. For the active, data processing part of the aid the Arduino platform was chosen because of its simplicity and big possibilities of help in different internet fora, for those who choose to create similar applications in the future. The main part of the project var the use of real-time information from the car?s on board diagnostics.
Modellering av indunstning på Södra Cell Mönsterås
Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.
Prediktorer för negativ kroppsuppfattning : - en studie av mediekonsumtion och psykologiska mekanismer
Betydelsen av mediekonsumtion innehållande ideal/utseendefokus och olika psykologiska mekanismer för kroppsuppfattning studerades genom en enkätundersökning. Urvalet bestod av 331 svenska unga kvinnor och män. För kvinnor fanns ett svagt positivt samband mellan mediekonsumtion och positiv kroppsuppfattning. BMI var en tredjevariabel alternativt en mediator i detta samband. Selektiv exponeringsteori föreslås som en förklaringsmodell för att förstå dessa resultat.
Lyx i lågkonjunktur : Ett marknadsperspektiv i svåra tider
This study will focus on the luxury market and how this market has been affected by the present recession. The economic downturn have had a major impact on today?s business and consumption, practically all industries have been affected. However there exist different opinions about how the luxury market have been influenced, certain experts mean that this segment is recession proof while others believe that this market will experience the worst side-effects. For that reason we find it interesting to analyze the luxury market and develop our own opinion about the impact of the recession.
Behovsstudie av ett energibutikskoncept för energiförsörjning utanför elnät : ? En småskalig fältstudie i Namibia
The amount of electricity is limited in Namibia and the large distance between towns andvillages complicates the energy supply in the country. Therefore an alternative way to provideaccess to appropriate energy technologies is needed. The Government of the Republic ofNamibia (GRN) has adopted an approach of helping off-grid households by establishing EnergyShops in each region in Namibia and these shops are going to sell basic renewable energy andenergy efficient products. The Renewable Energy Efficiency Institute in Namibia (REEEI), theinitiator of this thesis, is coordinating the establishment of these Energy Shops.The main purpose of this thesis was to examine the needs of energy products for the Namibianpopulation and develop an assessment method for the Energy Shop in how to select appropriateenergy products already on the world market. The purpose was also to develop a method forchoosing an Energy Shop.
Svenska konsumenters attityd till potatis : möjligheter för potatisbranschen
Until the sixties potatoes have had a unthreatened position at the Swedish dining tables, but
then different alternatives such as rice and pasta have become popular. In 2005 the Swedish
potato-consumption have more than hafted compared with the sixties, we have gone from
circa 90 to 40 kilograms per person and year.
This paper aims to provide those who are involved within the potatoe business
with an overview of the attitude and behaviour towards potatoes that are being held by
Swedish consumers. In order to reach to the conclusion, in- store interviews had been held
with customers in the cities of Stockholm and Malmö. The interviews showed that the typical
potato-consumer prefers to choose and in pick their own potatoes to a bag in the store in
favour of the pre-packed alternatives.
Based on the outcome of the interviews a number of conclusions could be
drawn. The consumers were of the perception that the pre-packed alternatives were too big
for their households.
Pedagogers syn på konsumtionen av socker och barns påverkan av pedagogers medhavda mat i förskolan
Det har varit många debatter i den svenska media om sockerintag och forskning som visar att barn i dag äter mer godis, läsk, snacks och mindre av frukt och grönt. Syftet med uppsatsen är att undersöka några pedagogers syn på kosten och dess sockerhalt i synnerhet, och de pedagogiska måltiderna i allmänhet, vid en förskola. Vad har pedagoger för syn på hur en bra förebild ska vara vid de pedagogiska måltiderna? Jag gjorde kvalitativa intervjuer med sex pedagoger. Kosten har förändrats mycket och sockerintaget har minskat på förskolan under de år de har arbetat, anser pedagogerna. Pedagogerna kan inte påverka kosten men kan välja att ta bort vissa livsmedel på avdelningen som de anser inte är nyttiga.
Second hand- och vintagekläder Vs. Nyproducerade kläder - En studie kring huruvida köp av andrahandskläder leder till lägre konsumtion av nyproducerade plagg.
I dagens Sverige konsumeras årligen stora mängder kläder. Nyproduktion av textil har en betydande miljöpåverkan med bland annat stor åtgång av vatten samt mängder av kemikalier. Ett alternativ till allt nyproducerat skulle kunna vara andrahandsmarknaden för kläder.Syftet med studien är att undersöka om de kvinnliga kunderna hos butikerna Myrorna och Beyond Retro konsumerar färre nyproducerade plagg för att de konsumerar second hand- och vintagekläder.Vi har använt oss utav en kvantitativ undersökning där vi intervjuat totalt hundra stycken respondenter i anslutning till Myrorna och Beyond Retros butiker. Vidare har vi genomfört fem stycken kvalitativa intervjuer med vana konsumenter hos ovannämnda butiker, för att fånga deras resonemang bakom svaren.De kvantitativa intervjuerna visar på att en liten majoritet anser sig konsumera färre nyproducerade plagg för att de konsumerar second hand- och vintagekläder. Samt att det överhängande motivet bakom köpen var att second hand- och vintagekläder är unikt och trendigt.
Smarta elnät i Sverige : Energibranschens förutsättningar och förväntningar
The need for a more efficient electrical grid has made the smart grid concept popular in recent years. The aims of this study are to identify the conditions in Sweden for implementing a smart grid and to analyse the opinions of stakeholders. One finding is that the large capacity of Sweden?s existing electrical grid decreases the immediate need for smart grid solutions. However, the rapid increase in wind power might push the development of a smart grid in the coming years.
Universitetsstudier utanför hemorten och dess samband med studenters alkoholbeteende och depressiva symtom
Universitetsstudenter har ofta ett riskabelt alkoholbeteende ochupplever depressiva symtom under studietiden, vilket kan ha svårakonsekvenser. Förklaringarna till alkoholkonsumtion blanduniversitetsstudenter har ofta fokuserat på studenters motivation tillsocialisering med andra studenter. Litteraturen har också fokuserat påförstaårsstudenters övergångsfas i förklaringarna till depression.Denna studie involverade 117 universitetsstudenter i ett medelstortsvenskt universitet. Studiens huvudsyfte var att undersöka omstudenter som bytte ort för att studera dricker mer alkohol ochupplever flera depressiva symtom än studenter som studerar i sinhemort. Resultatet visar på en betydande skillnad i alkoholkonsumtionmellan de två grupperna, vilket tyder på ett samband mellan flyttenfrån hemorten och alkoholkonsumtion..
Vindkraftetablering och uranborrning i Dalfors-Dalarna; Acceptans bland närboende
The dependency of fossil fuels has to decrease in order to reduce emissions of green house gases. Wind turbines generate electricity with low environmental impact, but the local opinion in Sweden is sometimes an obstacle to new developments. The acceptance of nuclear power increases at the same time. Mining uranium is once again on the agenda and prospectors are currently drilling for uranium. This cross-sectional study deals with acceptance of wind farms and uranium drilling.
Folk och land hör nära samman : En analys av stil, politisk berättelse och normalisering i Sverigedemokraternas partiprogram
This thesis in Art History and Visual Science is about values to graffiti and graffiti artist Banksy. I have studied values relating to Banksy´s graffiti images through which context they are placed in and where they are located. I have selected two different images of Banksy as an example on the basis of a transnational phenomenon, where the images that circulate in the public arena by street art and other images and imported into the galleries and consumption market. My conclusion is that the values of the images are based on the context in which each room have its surroundings and that therefore the impression will increase. The public space context, signal availability and the white cube context indicates art, and the commercial context signals goods and items that can be bought.
Optimering av OTEC-system
Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.
