Balancing packaging complexity by introducing platforms - A study at Carlsberg Breweries
Many consulting firms offer tailor-made solutions within complexity management, but these are not general frameworks built upon theories. Carlsberg are dealing with a large complexity within their one-way glass bottles, as they are growing by acquisitions, and are not attained enough economies of scale. This thesis balances the packaging complexity, with platform theory as a foundation. Twelve platforms were developed at Carlsberg, containing 21 bottles, and the calculated savings potential for applying these are EUR 28,9 million..
Ja det är klart att jobbet gör mig stressad! : En kvalitativ studie om juristers psykosociala arbetsmiljö.
Idag upplever nästan av alla kvinnor och män i Sverige sitt arbete som psykiskt påfrestande enligt Arbetsmiljöverkets undersökning om den svenska arbetsmiljön, främst individer i tjänstemannasektorn. Denna kvalitativa studie avser att undersöka juristers psykosociala arbetsmiljö i relation till krav, kontroll och stöd, för att slutligen se om det finns könsskillnader i hur arbetsreateradstress upplevs och hanteras. För att nå förståelse för individens subjektiva upplevelse av sin psykosociala arbetsmiljö så används en fenomenologisk ansats där empirin samlades in genom teoretiskt öppna intervjuer. Informanterna bestod av åtta jurister, fyra kvinnor och fyra män, verksamma i både privat och offentlig sektor. Intervjuerna analyserades deduktivt utifrån teorin Krav-kontroll-stödmodellen och modellen coping, men även induktivt för att få en fullständig förståelse.
Förståelse för visualiserad elförbrukning i publik miljö : En användbarhetsstudie av touchdisplayen Urban Energy
Hur publika displayer skall utformas och anpassas efter sin miljö på bästa sätt är ännu ett outforskat område. I takt med att miljöfrågor blivit än mer aktuella i dagens samhälle har det också etablerats ett behov av att förändra vårt beteende exempelvis i form av energieffektivisering. Syftet med denna uppsats är att undersöka hur en publik touchdisplay för elvisualisering skall utformas för att vara förståelig, intuitiv och säker från publik genans. En användarstudie i form av en utvärdering av en interaktiv touchdisplay kallad Urban Energy monterad i Göteborg har gjorts under ledning av Interactive Institute Swedish ICT. Touchdisplayens primära syfte är att uppmärksamma förbipasserande på stadens elförbrukning och uppmuntra till energimedvetenhet.I denna studie rekryterades 17 förbipasserande deltagare villiga att testa denna display med hjälp av två uppgifter och en enkät.
Kylbehovet hos ett batteribaserat elenergilager : Med avseende på kyldistribution, drifttemperatur, klimat, isolering och termisk tröghet
Under 2011 började MacBat AB ta fram ett elenergilager kallat Macbat Energy Storage System (MESS), vilket är uppbyggt av 360 stycken tvåvolts bly-syrabatterier inhysta i ett 20 fots container. Då bly-syrabatterier är känsliga för värme är den här studien inriktad på att utreda hur stort kylbehovet blir under olika förutsättningar där kyldistribution, drifttemperatur på batterierna, klimat, isolering och termiska tröghet är varierande parameterar. Det ska även avgöras vilken konfiguration av kyldistribution och isolering som ger lägst kylbehov för de studerade klimaten, vilka är av varmtempererad, arid och tropisk karaktär.För att besvara studiens två mål togs fyra matematiska modeller fram i SIMULINK. Två luftkylda och två vattenkylda där en av varje var isolerad med 100 mm mineralull medan den andra var oisolerad. För samtliga modeller varierades drifttemperaturen mellan 25 ? 35 °C och de studerade klimaten utgjordes av Phnom Phen, Kambodja, Djibouti, Djibouti, Bagdad, Irak samt London, England.
Användande av diffusionsspärr vid tilläggsisolering av äldre byggnader med trästomme
In the current situation a big part ofthe settlements that exist in Sweden isin need of renovation and energyefficiency in order to survive.Therefore, also many of the older houseswith a wooden structure are in a need ofenergy efficiency, which can be done ina variety of ways, including addinginsulation.This project deals with whether the useof a diffusion barrier or a vaporbarrier affects a wall structure byadding insulation to an older house witha timber frame. The insulation materialswhich are concidered in thisinvestigation are mineral wool and woodfiber insulation. Efforts are focused onthe effects of moisture on theseinsulation materials.To demonstrate the differences thatarise the moisture measurement programWUFI have been used to simulate avariety of wall designs. These designsare developed in consultation with theconstruction carers who are active inthe industry.Using WUFI graphs illustrating themoisture levels of the wall structureswere obtained and from these conclusionsvould be drawn. The work demonstratesthe differences that arise when using adiffusion barrier or vapor barrier inwall construction.

Traditionella metoder eller en dansande rosa panter? : En jämförelse mellan traditionella marknadsföringsmetoder och gerillamarknadsföring
Every day consumers are bombarded with different marketing messages from all possible directions. At the same time consumers starts to actively and consciously avoid these messages. Therefore, marketers have to start thinking outside the box and find new ways to get consumers' attention. One of these methods is called guerilla marketing. The strength of guerilla marketing is its way to be unexpected and unusual.
Energi- och kostnadseffektiva klimatskal : För lager-, industri- och kontorsbyggnader
A study to optimize insulation thickness for stock-, industrial- and office-buildings for external walls and roof in an economical perspective has been conducted on behalf of DynaMate. DynaMate?s role is to maintain all Scania?s buildings. Analysis has also included other parts of the building envelope, such as windows, exterior doors and industrial doors. In this thesis, three different types of exterior wall constructions has been investigated, these are a sandwich design consisting of sheet metal and a another one consisting of concrete, as well as a wall of concrete with a coating of plasters.
Psykoakustisk påverkan av basfrekvenser : Blir vi påverkade av låga basfrekvenser som vi inte kan eller knappt kan höra med örat?
This survey tries to find out if and how we can be influenced of extreme low and strong frequencies in the area 0-40 Hz. A group of 52 teachers/musicstudents and non musicstudents was trying to assess what they thought, experiences and tried to describe why they thought as they did, when they listen on three different versions of same musical piece. Without low frequent bass, original and strengthened bass, randomly mixed. Several different musical pieces was used in same survey. The work also makes a commitment to theories about the people's hearing and the will of ?selfmotion?.
Vägen tillbaka till hälsa : intervjustudie med kvinnliga deltagare från en stresshanteringskurs
In recent years more and more people have been sick-listed due to stress and it has happened to more women than men. The purpose of this paper is to see if recoveringfrom stress related states of ill-health can be promoted through participation in a stress management course. Five women who were or had been sick-listed and had participated in the life management course were interviewed. The results show that the course was an important forum for expressing emotions. The participants were more positive about the future after than before they entered the course.
Emotioner och emotionella uttryck i Sverige och Grekland
The purpose is to explore and describe norms and values concerning emotions and emotional expression inSweden and Greece from an emotionsociological perspective. Do emotional regimes on a national level existand if they do, how do they differ? To answer this question qualitative interviews have been conducted withnine Greek/Swedes, men and women of different ages, who have lived in both countries and who speak bothlanguages. A quantitative survey study, employing a survey previously used in a Swedish study about emotions,has also been undertaken. Previous studies have shown that emotional regimes do differ historically and acrosscultures, but no study so far has focused on the differences between examples of North European and SouthEuropean cultures.The theoretical framework consists mainly of Hochschild´s theories about feeling/display rules and emotionwork, but the analysis also draws on Collin´s theory of interaction ritual chains and on Sociology of Emotionsmore broadly.The results suggest that different national regimes can be distinguished primarily in terms of display rules andin the skills of emotional alternations.
IT-relaterade problem på arbetsplatser : En studie om äldre arbetstagares krav, kontroll och sociala stöd i IT-relaterade arbetsuppgifter
According to science internal communication is a complicated, yet very important, issue of organizations today. An organization with a successful internal communication shows better results both economically and in terms of coworker satisfaction. The two main theories on communication are sensemaking and transmission. After a century with a transmissionary point of view, researchers stress the importance of sensemaking internal communication.Main question of this thesis is ?Which of the two main theories is the most useful when anchoring important messages in large organizations??According to the results of this study, conducted by interviews, neither one is more useful than the other.
