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.
Utomhuspedagogik : En undersökning om pedagogers inställning till utomhuspedagogik i förskolan
This is a study where the purpose was to investigate whether preschool teachers have a positive or negative attitude to outdoor education. Their view of outdoors education is also treated. The methods used were questionnaires and semi-structured interviews. The survey was sent to all preschool teachers in three municipalities and on a social network. The interviews were conducted at a preschool, which had a form of outdoor profile.
Självskadebeteende : En studie om identitet och självuppfattning
The purpose is to illustrate the phenomenon of self-harm from a social psychological and sociological perspective. The purpose is furthermore to examine the role social relationships play in the individuals´ self- imagine and what role does identification play for anyone who harm themselves? We want to examine in what way social relationships are important and how they function for individuals who harm themselves, both once they have started to harm themselves, and if the relationships in any part caused the cutting to begin with.Questions:How do individuals shape their identity based on self- harm? Which self-image do individuals have who self-harm? Is there anything in the person's previous social relationships that have caused them to begin to hurt themselves?Method:In this paper we have analyzed five autobiographies. We have used open coding from grounded theory as analytical method and subject positions based on discourse analysis.Theory:We have used the Cooley concepts looking glass self, Foucault's theory of power, Giddens' concept of ontological security and existential anxiety.Results and Analysis:We found six different categories that we thought were central. These were negative self-image, guilt, lack of family support, negative experiences of others' views, the protective identity as self- harmer and insecure social relationships in school.Conclusion:The self-harming is a very complex behavior.
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.
eWOM: Kundrecensioners påverkan på konsumenter utifrån Regulatory Focus-teorin
This study examines the eWOM effect, more specifically: how customer reviews effects consumers. The study is based on a modified version of the Regulatory Focus Theory which describes consumer behavior using consumer consumption goals. The purpose of this study was to examine how positive and negative customer review's influence consumers when analyzing products that are equally characterized by two consumption goals: promotion and prevention goals. The authors combined quantitative (questionnaire) and qualitative (focus groups) research methods with the sample selection for both research methods being based on students of Södertörns University. Results indicate that negative customer reviews have a stronger influence on consumers than positive customer reviews when analyzing products that are equally characterized by the promotion goals and prevention goals.
After establishment closure : Individual characteristics that determine re-employment probabilities of displaced workers in Sweden
This paper studies the relationship between individual characteristics of displaced workers and the probability of re-employment. A competing risks hazard model is used, distinguishing between exits from joblessness to self-employment and to paid-employment. All individuals between 25 and 55 years of age, at the time of displacement, that suffered from at least one year of joblessness after being displaced between 1990 and 1998 due to establishment closures that occurred between 1990 and 2001 are included. This allows for the closure procedure to be between one and three years long. Each individual is followed, from the year of displacement until the year of re-employment or at the latest, ten years after displacement.
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.
Att leta efter kännskap : Hur lärare ser på utemiljön som en miljö för lärande
In outdoor education the empirical outdoor experience is an important basis for a learning process ? the teacher can affect learning with the choice of location. In order to develop the model in school, we need to build on teachers' perception of how their every day schoolwork looks like. This paper takes as its starting point at three teachers' perception of their learning environment and outdoor environments as well as a theoretical model of the site's importance in the learning process. The paper addresses both the importance of a structured and a unstructured meeting with outdoor sites.
Avloppsvattenbehandling med membranbioreaktor : En jämförande systemanalys avseende exergi, miljöpåverkan samt återföring av närsalter
In the pilot plant at Hammarby Sjöstad, Sjöstadsverket, several new methods are tested in order to achieve a good use of resources. When a new technique is considered it is often the performance of the technique itself, under given conditions, that is evaluated. However, in order to evaluate the overall function the whole picture is needed. With a system analysis it becomes possible to make a comparison where all the positive aspects are put up against the negative ones, for the technique itself as well as its requirements. In this way the influence that minor components have on an entire system can be considered.This report presents a system analysis of an anaerobic membrane reactor (MBR) with a VSEP-membrane (Vibratory Shear Enhanced Process).
Konstruktion av current conveyors via makromodellering
A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.
Projektmodell för införande av affärssystem : Ett konsultbolags implementeringsprocess i tjänsteföretag
Companies acquiring ERP systems are often dissatisfied with the project and therefore consultancy firms wish to make use of project models in order to achieve success in implementations. Since research on ERP implementations in service companies is limited, there is a need for mapping of critical activities in implementation projects in this line of business. Under these premises, the purpose of our master thesis is to develop a model for implementation of ERP systems, specified in activities, which can be used by mid-sized consultancy firms with mid-sized qualified service companies as customers.A literature study including project models, modern models and methodologies for ERP implementation, commonly existent activities, success factors and system development methods was carried out. Starting out with this, a theoretical model for ERP implementation was generated. In excess of this, a case study was conducted, where the implementation of the ERP system Microsoft Dynamics AX at the service company Eurostep, performed by the consultancy firm Medius, was studied.
Sociala medier i Kina : En studie om användningen av sociala medier i en diktatur
The current research examined whether motives, traditional mass media consumption and individual differences (social activity and political interest) predicted the use of social media among a group of university students in China. In coherence with Uses and Gratifications assumptions the study found that the factors differentially predicted the extent of media use. Information seeking, social interaction and affinity were the main reasons for using social media. There was a negative correlation between television viewing and use of social media, in addition to a negative correlation between information seeking and use of the media. Results further suggest that social media are used to enhance social capital, since student?s being socially active offline, tend to use the media to a greater extent than those less active..
Kvantifiering av föroreningstillskott från dagvatten inom skyddsområdet för Göta Älv : en simuleringsstudie med modellen SEWSYS
The river Göta Älv reaches between Vänern and Gothenburg and is the main raw water source for Gothenburg that supplies about 700 000 people with water. To protect and maintain a high water quality, continuously samples and water analyses are made throughout the river. In 1998 a protection area was founded between surte and Lärjeholm where the raw water intake is. This was made to increase the awareness of the importance to protect the water. However, there is a lot of contribution of untreated stormwater to Göta Älv within the protection area.Göteborg Water and Sewage Works commissioned this thesis where two areas, Tagene industrial area and Kärra residential area, with untreated stormwater outlets within the protection area are studied.
Förändringsarbete i skolan - med lean som inspiration : Lean-tavla - för röd tråds skull!
During the middle of the 18th century the development of Toyota Production System, TPS, started in order to streamline the processes. TPS was based on the principles of assembly line production but unlike previous performers Toyota let the manufacturing be constantly affected by demand. At the end of the 18th century TPS was described by Womack and Jones in the book "The machine that changed the world - the story of lean producion" where TPS got the name lean. The principles behind lean is to maximize customer value and eliminate waste which means making products and services more valuable to the customer. 1Lean was for a long time a philosophy and an approach limited to industries and production based companies.
