Mobil kommunikation och högre tillgänglighet vid längre elavbrott : Exemplet stormen Dagmar och 4G-kommunikation inom smarta elnät
To be able to secure a safe and reliable power supply is becoming increasingly important since society depends on services and functions that need continuous power supply. The delivery rate in Swedish power supply is 99.98 % which insists on a high availability. During the past decade several storms has passed Sweden which resulted in large amount of tree felling leading to extended power outages. During these storms many socially critical activities, such as electric utility company Fortum, experienced disruption in mobile communication which affected the crisis management. This paper has investigated Swedish mobile operators? crisis management at Hi3G, Tele2 and TeliaSonera with a case study of the storm Dagmar that hit Sweden during December in 2011.
Prognostisering av räntabilitet på eget kapital - En jämförelsestudie av tre regressionsmodellers prognosförmåga applicerat på svenska data
A multivariate cross-sectional model is used in this thesis to proxy for expected earnings and to estimate return on equity for 214 companies over the period 2009-2013, using Swedish data. The model, which has never been tested on Swedish data before, is first confirmed to function as a forecasting model for expected return. Furthermore, the model is evaluated through a comparison with two univariate models based on the assumption that return on equity follows a mean reversion process. Forecast accuracy is calculated as the difference of estimated returns and actual returns. The results show that the univariate models' forecasts are superior to the multivariate model's..
Viskleken : Ett gestaltande arbete från text till upplevelse
In my project, Cups on the run, I have studied the relationship between ceramic utility objects and different environments, when moving them off the table. My background as a potter has been the starting point. From there, I wanted to see if I could expand my craft to the space beyond. With the cup, which for most people has a clear function and a relation to us human, in repetitive structure I explored the spatiality and architecture in various environments. Life fascinates me through how everything is made up of tiny parts that together create the tangible and intangible.
Läraren - från ensamvarg till lagarbetare? : En studie av hur lärarrollen har definierats och förändrats i grundskolans läroplaner från 1962 till 2011.
Forming teacher teams is currently the standard way of organizing teachers in Swedish Compulsory Schools. This is the result of a process that started in the 1970s.Traditionally the culture of teaching has been one of isolation. Once the door to the classroom is shut, what happens behind the door is up to the teacher to decide. Over the past thirty years a lot of time has been dedicated to making fundamental changes in the way teachers interact with their colleagues. Today the idea of teachers forming teams is generally accepted but still the core of a Swedish teacher?s job is that of a lone worker.
Stress i socialt arbete : om socialarbetares upplevelser och hantering av stress i sitt arbete.
The purpose of this study is to use a qualitative approach to get an understanding of what is expected of social workers targeted towards women managers in social services. Nine social workers were interviewed. The empirical data was then analyzed on the basis of gender theory. Respondents did not see their supervisor as a manager but more as a social worker with special tasks. Our empirical data indicates that there is a strong belief that men and women possess different properties.
Skillnader i variation : Lärares uppfattningar av variationsteori och hur variationsteorin blir en guidande princip
The gap between practise and theory is often described in negative words in teachers? professional lives. Learning study is a model for teachers´ professional development where a theoretical framework is used to enhance practice. The theoretical framework used by teachers in learning study is variation theory. In this study the research object is variation theory and the aim is to present how variation theory becomes a guiding principle to understand teaching and learning processes.
Faktorer som påverkar vindkraftsutbyggnaden
Wind power is expanding rapidly in Sweden. Increasing amounts of wind power sets higher requirements on balancing power and grid expansions and would affect the whole Swedish electricity system. The aim of this report is to examine the factors affecting the wind power expansion in Sweden. How many wind power plants projects will obtain building permissions and what costs and revenues can be expected? How much balancing power will be required and does a changing geographical distribution of the wind power plants reduce the need of balancing power?A survey of the county board?s official applications has been made and out of all the applications, corresponding to 80 TWh produced per year, about half of the applications are expected to obtain a permit with a major portion of them located in the north of Sweden.Especially older wind power plants, deriving revenue from Nord pool, find themselves today in a complicated financial situation.
Tests of optimal capital structure theory and pecking order theory using a binomial approach- a study of Swedish firms
This master thesis concerns whether Swedish non-financial listed firms act in accordance with the optimal capital structure theory and/or pecking order theory. The examined period is 1998-2004 and we discover that Swedish companies neither follow optimal capital structure theory nor pecking order theory. From our results we conclude that there exists no single point of the capital structure which is optimal. Rather it seems as if the optimal point lies in-between an interval from 0 to the industry average, where firms tend to be indifferent to their debt-ratios. Our results show that Swedish companies prefer internal financing followed by equity and as last choice debt issuance..
Bilden av ledaren - en tolkning av fotografier i årsredovisningar
The visual representation of management (board of directors, chief executive officer and executive management) in annual reports is an area of scholarship that has not been explored much. In the present study a sample of 87 annual reports from business enterprises within a Swedish context, comprising about 300 photographs, was analyzed using an explorative method of analysis based on semiotics and grounded theory. The influence of the context on images raises a question discussed in the study: Should the photographs in the annual report be categorized as portraits, advertisements and others or should the annual report be regarded as a genre of its own? The photographs showed patterns of homogeneity regarding gender, dress, gestures, colours, pictorial compositions et cetera. The position of the (male) CEO is privileged, but he is also connected to the group through various means like dress and style, thereby further underscoring management as a male enterprise and demonstrating the importance of the suit and necktie in creating homosocial bonds.
Termisk analys av kompakta jordvärmesystem - Sensitivitetsanalys och korrektions faktorer baserat på fältmätningar i referensanläggningar i Östergötland
Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.
Teorin om "Just War" -Rättfärdigande eller Urskuldande?
This text concerns itself with war, the just war theory, and the application of that doctrine on the ?war on terrorism?. I present different views on the theory's place in the discourse, its relevance for unconventional wars followed by the analyses of above mentioned empirical situation.Particular interest is given the criteria concerning proportionality, both ad bellum and in bello, due to in part its difficult nature, and the attention it has received from others. This paper asks the question: Is the just war theory adequate for analysis of modern war?There are few alternatives.
Vampyr och nagelbitare : En genre- och diskursanalys av barn- och ungdomsrysare och deras ämnesord
This master's thesis in Library and Information Science examines how the genre division of the horror fictionis constructed at the children and youth department of a library by studying subject headings of the titles.The aim is to examine what is included in the genre, in the two labelings called vampire and nail-biter/spine-chiller, what separates them, and what difference there is between children and youth thrillers/horror fiction. Also the cover designs and how readers portray these books are studied. The study is made in order to develop the knowledge of the genre to help librarians and borrowers. The great popularity of the genre among borrowers and people in general, and the importance of having knowledge of things that borrowers are interested in, are the motivation of performing the study. The method is a case study and conducted with and based on genre theory which shows how a genre is defined, how it can be divided and what conventions there are for the horror fiction in particular.

This wasdone through an examination of the development in China.
En studie om införandet av expected loss model : - En mer tillförlitlig och relevant metod för nedskrivning av finansiella tillgångar?
Accounting has been critized for being one of the leading factors in the latest financial crisis. One of the primary problem areas was identified as delayed recogonition of losses on financial instruments. Consequently, a new impairment model is being developed and is to be namned expected loss model. The difference from the present model, incurred loss model, is that it takes losses into consideration on an much earlier level. Even though the model may be theoretically feasible, in practice it may implicate a number of issues.
