Företagande som strategi: -Frihet kostar trygghet, det måste man kunna leva med
Over the last decade the conversation on entrepreneurship has been both worldwide and intense. In Sweden, as in many other countries, this conversation has also concerned women?s entrepreneurship. Parallel with this conversation has been the debate on women in leading position in large corporations. This thesis aims to find out why and how women use entrepreneurship to handle existing conditions in life (such as the hardship of combining a traditional career with a traditional family life) and to create new conditions that suit them better.
VDC i produktionsfasen Implementering av virtuellt byggande för Veidekke Bygg Väst
This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.
Renovering av flerbostadshus - en studie om energieffektivisering och lönsamhet
In today?s society a large focus is put on energy systems and how our energy systems are built up. In order to make sure that we in the future still can enjoy the living standards that we are used to today, Sweden and EU have made a number of decisions on making our energy system more energy efficient and consequently reduce the usage of energy resources. By 2020 the European Union should have reduced its energy consumption by 20 % compared to 1990?s level, and by 2050, 50%.
Effektiviseringspotential inom industrisektorn : Energibesparing vid frekvensstyrning av centrifugalpumpar ? en fallstudie
The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..
Att vårda patienter i ett sent palliativt skede : Ur ett sjuksköterskeperspektiv
Background: Nurses´daily has to face death and dying in their work with patients in a palliative state. This means both emotionell and workrelated challenges. However nurses in this context are not experiencing more stress then others.Aim: The aim is to describe nurses´experiences of caring for patients in a palliative state.Method: A litterature review based on ten qualitative articles published between 2006- 2012. To collect data we used the databases Cinahl, PubMed, Nursing Allied Health Source and Medline. We worked with Fribergs (2006) model ?Contribute to evidensbased care with a base in analyses of qualitative science? in the analysis.Result: Four main themes were identified; The meaning of the nurses´ spirituality in the care, Why the nurse choose to work in this field, To be certain in the professional role and The meaning of the caring relationship.
?Ja, då Googlar man, som man säger? ? en kvalitativ studie av PRO-pensionärers informationssökning
The purpose of this thesis is to gain a better understanding of how elderly people seek and use information in everyday situations. A further aim is to suggest ways for the library to offer more services specifically tailored for pensioners. This is an important topic as pensioners are a rapidly growing group of library users. We conducted qualitative interviews with four elderly people concerning their information needs in everyday life, and discovered that they rarely use the library, preferring instead to get their information from various internet sites and their pensioners? organisation.

Det sinnliga upplevandet av landskapet : en teoretisk undersökning av positiva emotioners roll vid utomhusrekreation
The purpose with the paper is to theoretically investigate how sensory experience and positive affect in contact with outdoor environment can promote health by 1) develop a model of the sensory and emotional processes based on multiple code theory (Bucci, 1997) and 2) examine if this model can increase understanding of the processes that takes place in outdoor recreation, the way this is described in environmental psychology research and theory.
The paper starts by introducing research and perspectives concerning outdoor recreation.
Different theories of nature?s health promoting effects are described. These include the
restoration theories of Roger Ulrich and Steven and Rachel Kaplan, theories more concerned
with outdoor activities and a theory combining these two perspectives called instorative
theory.
After this sensory and emotional information processing is examined through the works of
Wilma Bucci and Jean Ayres. Antionio Damasio?s theories of emotion and Daniel Stern?s
concept of vitalityaffects are than introduced to extend this reasoning.
En kvalitativ studie om före detta kriminellas upplevelser av stöd och hjälp.
The aim of this study was to examine former criminals? experiences of help and support of importance to leave a criminal life style. The study consists of six interviews with former criminals and earlier studies on the subject. These studies show that relapse in crime are most common among those who are socially excluded from society. They also show that important factors to end a life in criminality are for example a supportive social network.
Diagnostiksystem i gaffeltruckar
This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.
Boktryckaren på Visingsö: en granskning av Sven Almqvists forskning om Johann Kankel
The aim of this thesis is to examine Sven Almqvist?s research on the 17th century book printer Johann Kankel who was employed by count Per Brahe the younger on the island of Visingsö. A model to describe the communications circuit, constructed by book historians Thomas R. Adams and Nicolas Barker are used as well as the historical source criticism method. This model consists of the five phases: publication, manufacture, distribution, reception and survival.
VIX: ett mått på marknadsosäkerhet : Hur påverkas VIX av schemalagda nyhetspubliceringar?
This study is based on interviews with heads of unit, care staff and senior representatives from a total of six people. We have in this study directed our focus on care quality in the elderly as a concept in development. It appears, when the elderly do not have any dependents, it is even more important that staff supports some extra where no relatives are involved.Quality of life is the broader concept of good quality care and where a good quality of care is a necessary condition for a good quality of life. According to the social services care is the target that older people will live a good life and be allowed to live in a safe environment, which we intend to investigate in this study. Opportunity for greater influence should now be given to older people and their families on how interventions should be designed and implemented.
Distributionsekonomisk optimering av dagligvaruhandelns lokalisering : förstudie till ett forskningsprojekt
The structure and performance of grocery distribution in Sweden has changed profoundly since the second world war. Increasing access and usage of the private car, in combination with an accommodating town planning has enhanced the exploitation of scale economies within distribution firms. There is, however, some ambiguity concerning the overall efficiency of the distribution system when the costs associated with travelling and purchasing performed by households are treated as an integrated part of the total distribution cost function. The purpose of this master thesis is to develop the foundation of a spatial optimisation model, which defines the most efficient distribution system. The underlying idea is that the optimal localisation and size of grocery stores is a function of economies of scale within the firms weighed against distributions costs within the households, such as transportation costs.
Mobilannonsering: Hur ett värdenätverk formas kring en ny mediekanal
Mobile telecom and the Internet are converging, which opens new possibilities for market actors to create business through the mobile handset. At the same time market experts are predicting that mobile operator?s existing dominance in the telecom market will in the future decline as new technology such as VoIP and services will erode the operator?s traditional revenue model. This implies that mobile operators will need to rethink their dominant business logic to create new value for their customers. Mobile operators are aiming to expand their existing revenue model through advertising in the mobile handset and are searching to create new business models that evolve advertising sales.
