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.

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.

Kan supplementering med omega-3 under graviditet påverka allergiprevalens hos barn?

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.

Euthanasia: A Critical Analysis of the Physician's Role

Sometimes relatives have taken me on one side and told me they cannot bear it any more:"Isn't there something you can do to end it all?"More often requests for euthanasia have come from those who are ill. I remember visiting a man with lung cancer. He asked his wife to leave the room. As she closed the door he leaned over and grabbed my arm.

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.

Effekter av funktionell träning och medicinbollkast för att optimera kinematic sequence och x-factor stretch i golfsvingen

The interest for functional strength training in golf has grown the last decade and scientists are always trying to find training stategies to improve the biomechanical aspects of the swing. Kinematic sequence contains a proximal-to-distal sequence order towards impact, and an effective kinematic sequence in the down swing begins with a rotation in the pelvis and follows by an activation in thorax, arms and club in the respective order. The rotational torques in the proximal segments wanders through the body and to the more distal segments to create an effective energy ? and power transfer at impact. The x-factor stretch is the seperation between the rotation in the pelvis and the thorax at the top of the back swing and at the beginning of the down swing.

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.

?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.

Vision och verklighet - En fallstudie av hur biblioteket på Linnéskolan i Älmhult arbetar för att hjälpa eleverna nå upp till aktuella lärandemål

The purpose of this master thesis is to investigate if and how the school library in Linnéskolan in Älmhult is working towards the learning goals that can be find in the different school documents that are represented by the municipality of Älmhult. This includes goals for the school, for the school library and for the subject of social studies in the ninth grade. We also want to investigate if the school library helps the students to reach the learning goals and if there are any factors that can be improved in the school library. We have used an evidence based approach to define factors in the school library that can be improved. In the chapter that describes our theoretical approach, we have also discussed three different pedagogical theories; teacher-centered teaching, individual constructivism and social constructivism.

Oxytocin-Ett risktagande eller en tillförlitlig behandling vid långdraget förlossningsförlopp hos förstföderskor

Background: Breastfeeding frequency decrease in Sweden and infants born preterm is a particularly vulnerable group to not be breastfed according to current recommendations. Mothers of preterm infants have an extra need of support from the health care system. Mothers' self-efficacy in breastfeeding affects the outcome of breastfeeding. Health professionals' attitudes to breastfeeding have an impact on the breast feeding support they provide to the mothers.Aim: To investigate whether an intervention could strengthen self-efficacy in breastfeeding among mothers of premature babies. A further aim was to investigate whether the intervention influenced health professionals' attitudes to breastfeeding.Method/Design: An experimental study with quantitative approach in the form of questionnaire survey was conducted.

Vasastaden och gentrifieringsprocessen 1970-2010

Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.

LIKHET ELLER SKILLNAD? : Om hur ambassadörer för UNICEF i Sverige representeras i relation till barn/?de Andra? utifrån könade och rasifierade diskurser om bistånd

This essay aims to examine what subject positions are possible within the discourse of relationship anarchy. Through semi-structured interviews with four people who define themselves as relationship anarchists I've made a discourse analysis to determine how these relationship anarchists explain what, in the discourse they?re in, is described as an relationship anarchistic way of being, what isn?t and how they relate to this. Relationship anarchy is described as an ideology based on freedom. It is about the right to define their relationships as they like, as something constantly changing and that does not hold a specific value based on its label.
