Att mäta publicering av artiklar: En tillämpning av bibliometri på evidensbasering inom socialt arbete
This thesis examines the scientific publishing in the subject area of evidence based practice EBP in social work. Issues are: How has this publishing evolved, separately and compared to the publishing about evaluation in social work? What authors/countries have produced the largest numbers of articles? What journals have published the largest numbers of articles? Which are the most frequent co-occurrences of a selection of terms? 161 records for articles from 50 different journals were selected from Social Services Abstracts using subject of journal and a query as criteria. For each year, the number of articles about evaluation in social work was larger than about EBP. A decline in the publishing about evaluation coincide with a growth in EBP after the year 2000.
Förbättring av upplösningen i Landsat 7-bilder med hjälp av bildfusion
The purpose of this master's thesis is to evaluate whether it is feasible to use the panchromatic band of Landsat 7 in order to improve the spatial resolution of colour images. The images are to be used as texture in visual databases for flight simulators and for this reason it is important that the fusion preserves natural colours.A number of methods for fusing panchromatic and multispectral images are discussed. Four of them are implemented and evaluated. The result is that standard methods such as HSI substitution are not suitable for this purpose since they do not preserve natural colours. However, if only high frequencies of the panchromatic image are used the resolution can be improved without noticeable colour distortion..
Lean & Kaizen -dröm eller verklighet? : En kvalitativ studie med kundperspektiv i fokus
This qualitative study involves the implementation of Lean and Kaizen methods in a Swedish service industry. Lean philosophy is based on a method to achieve more with less. In practical terms this means that the use of an organization's resources is improved. The origin of Lean is the Toyota Production System. Now, Kaizen methods give managers and employees a better more efficient system to reach their goals within the organization or company.
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.
Motivation på SFI : En kvalitativ intervjuundersökning om fyra lärares uppfattningar kring hur man kan arbeta för att motivera eleverna på SFI
Due to lack of knowledge about motivation in Swedish for adult immigrants (SFI ), I have chosen to write about motivation. Motivation is a complex concept to understand. It has different meanings depending on what context the term is put in. In this study , you will read about the external and internal motivation . But also about integrative and instrumental motivation.
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.
Allmänhetens involvering i planeringsprocessen : En studie av två olika metoder för gatuundersökningar
It might seem obvious that public opinions should be included in the planning process. However, it is not clear to what extent. Statutory forms of public participation attract little interest since many people feel that it is hard to make a difference. The purpose of this study was to engage those that normally do not get to speak their mind in the planning process. In this study, two methods for conducting ?on-street surveys? were investigated.
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.
Byggnadsminnesmärkning eller varför är det så ont om Q?
This thesis deals with our heritage and the care of old buildings. In order to limit this vast area a specific attention has been brought upon the process of giving buildings a certain level of protection and after decision having it taken away, instead of giving a stronger protection level.Further limitation has been done through the choice of four buildings in Lund, within Lund University campus. These buildings all lost this certain level of protection. The participants in these kinds of cases have a level of power, what argumentation did they use?The methods being used are discourse analysis, phenomenology and the daily methods of the building care field..
Scrummästarens roll som konflikthanterare : Konflikthantering i agila projekt
Companies show interest in agile methods, but this can be challenging since these methods to a certain degree stand against traditional project methods. If the use of agile methods increase it is of importance to clarify what mechanisms that are significant to a successful result. The aim of this study is to clarify the role of the scrum master regarding conflict management in agile groups. The goal of the study is to better prepare the ScrumMaster to be ready to help the group in a conflict situation. In this examination a qualitative method has been used where five scrum masters, active in agile projects, have been interviewed about their role in conflict management.
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.
Tillförlitlighet hos trafikolycksklassificering
Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Evaluation of Different Extraction- and Analysis Methods for Calprotectin in Feces
Background Calprotectin is a protein expressed in the cytoplasm inside the neutrophile granulocytes. During inflammatory bowel disease (IBD), the neutrophile granulocytes are involved in a complex interaction at the inflammatory area where they die and release their content into the intestinal lumen. Therefore, calprotectin in stool is a suitable marker for diagnosis and measurement of the disease-activity in patients with IBD. The most commonly used method to detect calprotectin in stool is ELISA, but the process of manual preparation of stool samples is time-consuming.Aim The objective of the study was to evaluate an extraction method that could replace manual preparation of fecal samples and to compare different methods for measuring Calprotectin in stool using two ELISA-methods from two manufacturers and one rapidtest.Methods For extraction of calprotectin from stool samples we used sample collector tubes from Epitope Diagnostics and fecal preparation kits from Roche. Two different ELISA-kits for measuring calprotectin concentration in stool were compared.
Fälttest av en ny metod att med objektiva mätmetoder karaktärisera egenskaperna hos ridunderlag- en pilotstudie. :
Background
Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses.
The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs.
