Kan en periodiseringsbaserad investeringsstrategi effektiviseras med hjälp av fundamental analys?
This paper investigates whether the traditional accrual based trading strategy first documented by Sloan (1996) can be refined using fundamental analysis. Specifically, this is done by implementing the composite signal F_SCORE introduced by Piotroski (2000) to identify financially strong or weak firms. We find that by applying both investment models simultaneously, in a model we call P_KOMB, the mean market-adjusted return earned by an investor exploiting the accrual anomaly can be increased by 14.8% annually. This is achieved by taking a long position in strong firms (as defined by the composite signal) in the lowest accrual portfolio, while an offsetting short position is taken in weak firms in the highest accrual portfolio, repeated annually between 1997 and 2007. Consistent with prior studies, positive market-adjusted returns can be attained through assessment of accruals as well as key value drivers found in historical financial data.
Psykoterapins plats i offentligt finansierad sjukvård : Om mellanchefers attityder till psykoterapi som behandlingsform
Denna explorativa studie utgår från ett intresse för samspelet mellan den kliniska vardagen och det omgivande samhället. Sju mellanchefer på vårdcentraler och vuxenpsykiatriska öppenvårds-mottagningar har intervjuats i syfte att undersöka deras föreställningar och attityder runt psykoterapi som behandlingsform, exempelvis deras tankar om psykoterapins verkan och tillgänglighet liksom deras medvetenhet om och attityder till en ökande betoningen på evidensbaserad vård. Frågeställningar: 1. Hur beskriver cheferna psykoterapi som behandlingsform och vilka attityder har de till psykoterapi.2. Hur upplever cheferna psykoterapins villkor, exempelvis beträffande gränsdragningar och evidensbaserad vård, och vilka attityder har man.

This essay explores how artwork in the public space can be analysed, conceptualized and described by bringing attention to site. Through an analysis of artworks in the yearly art exhibition of Fittja Open 2011, the essay draws attention to site-specific art and structures of power. The principal aim is to present not only the exhibition of Fittja Open 2011 but also other artwork in the public sphere in Fittja, a suburb to Stockholm. From this point of departure other interests evolve that concerns the "image" of Fittja. The analysis, based on research in art history, architecture, ethnology and philosophy as well as qualitative interviews, also focuses on understanding the role of site and the relations between art practice, institutions and site.The result shows that there are problems with a ruptured interface between the artwork and site.
Datorbaserad examination: En studie om användarhinder och systemacceptans bland lärare
The aim of this thesis is to examine how teachers use computer based assessment in their work and what user barriers they experience while working with computer based assessments. The result of the thesis is meant to provide an understanding of which factors affect the use of computer based assessments and how a company who provide computer based assessments applications can increase the rate of use amongst teachers.To investigate this, the author examined a company in Sweden who provide a computer based assessment application for both universities and high schools. The study was carried out at two different schools, a university and a high school, both located in Stockholm. In total nine teachers were interviewed. The author also conducted observations at the company whose computer based assessment application was examined.The author?s findings suggest that a lack of functions within the application and lack of costumer support from the company all negatively impacted the teacher?s use of the application.
Individen kommer inte långt själv för ensam är man ingenting : En studie om arbetsmiljöns påverkan på hälsan
The purpose of this thesis is to achieve a greater understanding of how the social workers at the family unit in one of Stockholm municipalities comprehend the work environment at the workplace. Our aim is also to find out how the work environment can affect the health of the social workers in the form of their wellbeing and comfort at the workplace. In order to answer our purpose we conducted interviews of all social workers at the family unit in one of Stockholm municipalities that describe how they experience the work-environment in the workplace and how it influences their health. We have analyzed the interview material in a thematic analysis based on three theoretical perspectives; SOC, claim ? control - support and Human relations. We have also coupled the interview material to the background chapter in this thesis that describes how a good working environment should be structured. The chosen method characterizes an abductive process.
Är avkastning allt
Scarcity due to supply, demand or in time is all factors that affect consumers´buying behavior. The scarcity principle describes how scarce resources appear moreattractive to the customer's eyes than unlimited does. When something is scar thecustomer often draws parallels to the quality and price, that the product will bemore expensive and better. People hate to be deprived of choices. When a certainproduct is scar, the customer will desire the product even more.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicin and Clinical NutritionAbstractTitle: Does supplementation of omega-3 during pregnancy affectprevalence of allergy in infants and children?Author: Peter Eliasson, Anna RahmSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 ECTSDate: 2012-04-12BackgroundEpidemiologic research has shown an association between a high intake of fish and allergy.The underlying theory is that allergy develops already at a prenatal stage and food intakeduring pregnancy has been shown to be significant. Conducting research on allergy isproblematic since it has genetic, as well as enviromental, determinants.ObjectiveThis thesis attempts to conclude and evaluate research on a connection betweensupplementation of omega-3 during pregnancy and allergic outcomes in infants and children.Search strategyThe literature search was conducted in the databases PubMed and Scopus. Among thekeywords chosen were omega 3, supplement, pregnancy and allergy.Selection criteriaHuman RCT, that measured allergy, where the intervention consisted of supplementation withomega-3 for at least ten weeks during pregnancy and ceased at birth.Data collection and analysisThree articles were chosen for this thesis. The articles were examined using templates fromSBU and the quality of evidence was evaluated according to GRADE.Main resultsNone of the articles showed a protective effect on allergic outcome but in one of the studiesthere was significant reduction in eggallergy and another showed significant lower occurrenceof severe eczema.ConclusionsSupplementation with omega-3 during pregnancy does not occur to have an protective effecton allergic outcome in infants and childen but the evidence for this is considered to bemoderate.
Hantverket bakom intervjun: Studenters framställning av kvalitativa intervjuer som undersökningsmetod
When producing an interview report the researcher is put to the test of describing the qualitative interview method in terms of assumed orderly steps and procedures taken during the interview process, while at the same time account for a very social dynamic process. In practice, even the most carefully prepared scenario for a qualitative interview study probably does not correspond to the expectations made. What happens between the plans and the actual interview itself? This issue is investigated by contrasting the actual engagement of the participants in an interview project to how these relationships are accounted for in Master thesis from the Swedish School of Library- and Information Science in Borås. Theory and methodology from Actor Network Theory (ANT) have been applied into the area of qualitative interviews.
Det främsta arbetsredskapet ? Sjuksköterskans erfarenheter av det vårdande samtalet med patienter inom psykiatrisk öppenvård
Introduction: The conversation is one of the main components of the nursing process in psychiatric care. The preunderstanding on this research field is described based on theoretical concepts that together form the basis for understanding the study; nurse's role in psychiatric care, communication and caring relationship, as well as theories of the caring conversation and person-centered care. Research on the caring conversation as a theory and how it is experienced by patients existed, however, no research from the nurse's perspective was found.Aim: The aim of the study was to describe nurses' experiences of the caring conversation with patients in psychiatric open care units.Method: Qualitative research interviews were conducted with six nurses working in outpatient psychiatric care in the west region in Sweden. The interviews were recorded, transcribed and then analyzed according to the qualitative content analysis as described by Graneheim and Lundman (2004).Results: Four categories with related subcategories were distinguished throughout the analysis: The caring conversation, The importance of the care plan, Limitations and Caring based on the patients narrative.Discussion: An uncertainty about what caring conversation is and what it should contain creates uncertainty in the nurse's work. This results in a need for training for the individual nurse and the further research to obtain evidence for the importance of conversation in caring work.
Det är hans känsla! : En studie om hur genus och jämställdhet kommuniceras i klassrummet
The aim of this study is to describe, from a didactic point of view, wether gender norms are challenged and sex equality is maintained when two teachers in grade one communicate with their pupils. This is based on the existing norms in our society which generates into certain expectations of how one should act depending on wether you are a girl or a boy. In addition to this, the lack of equality between women and men is a global question. The norms and conditions in society are reproduced, but can also be deconstructed in school (Martinsson and Reimers 2008, p. 8).

En jämförelsestudie mellan OpenGL 4.3, OpenGL ES 3.0 och WebGL 1.0
OpenGL is a standard API that is used to manage 3D graphics on desktop computers. Although OpenGL is independent of customized hardware it?s not suitable for all kinds of devices. Therefore both OpenGL ES andWebGL was created. These can be viewed as subsets of OpenGL.
Musikelevers övningsstrategier : En observationsstudie av tre 18-åriga stråkelever
The aim of this study is to examine which strategies three 18-year-old string students (one violinist and two cellists) use when they practice on their own. The empirical data for the study come from six observations of the students? practicing on certain pieces that were handed out to them. During the observations, the students filmed themselves, and no one else was present in the room during the practicing sessions. The observations were later transcribed and analyzed, which means that its contents were compared and contrasted to results of previous research in the field of practicing.The results of this study show that all three participants first tried to gain an overview of the piece by playing it through from beginning to end.

?Jag tycker bara att jag gör vad jag vet att jag kan göra? : en undersökning av en webbaserad bibliotekskatalogs användarvänlighet utifrån användarnas perspektiv
The purpose of this Master's thesis is to examine whether a web-based library catalogue is to be considered user-friendly. We have examined this from a user-perspective by interviewing users of a web-based catalogue at a public library. In order to get a picture of the user-friendliness of a catalogue, the thesis is centred upon the following questions: How is a web-based catalogue used? What problems do the users experience? How is the catalogue perceived by its users? Since the producers of these catalogues now are taking into account the research upon human-computer interaction, we are also interested in finding out whether a web-based catalogue is more user-friendly than a more traditional OPAC. We do this by comparing the results of our examination with earlier studies of OPAC use.
