Den kombinerade effekten av query-expansion och query-strukturer på återvinningseffektiviteten i ett probabilistiskt system
This thesis deals with query formulation in full text retrieval. The variables studied were query expansion and query structur[INS: e :INS , and the aim of the thesis is to study their co-effects on retrieval performance in a probabilistic system. The expansion was made with synonyms, and the structure by expressing facets and phrases. The study was performed using QPA, Query Performance Analyzer, which includes InQuery retrieval system and a sub-collection of TREC documents with its topics. The measurement used was precision at 11 DCV points.
Bonus, ju mer desto bättre?
The economic climate that has been going on for the last years has more or less affected everyone. This has created a need to get more knowledge about how our banks work and also how peoples own personal financial situation looks like. When our banks over this last period have compensated their employees with even greater deals of money, reactions has gone to the roof. This discussion has made us interested in the subject, which led to the decision to write an essay about remunerations within banks.The purpose of this essay is to investigate if our banks remunerations to their employees have any effect on their profit numbers. Does the size of the compensations vary with changes in the market? Do larger compensations contribute to a greater result?The study will look at Sweden?s four largest banks, Handelsbanken, SEB, Nordea and Swedbank.
Kreditklassning av aktiebolag i Sverige, en logistisk regression
Predicting corporate failure is an increasingly important topic in the world of economics today. This paper, with the help of the credit ranking company Syna AB, aims to investigate a few different statistic strategies to do just that. This task is accomplished by using a data material of 250 000 Swedish companies divided into two subsamples. The first sample is used to develop the model and the second as a validation sample. The model developing sample holds 160 000 companies divided into five different subgroups based on size and age.
Utveckling och psychometrisk testning av "Pain Impact Inventory" - en jämförelse mellan två olika ansatser
The aim of this study was to develop and psychometrically evaluate an instrument for measuring the impact from chronic pain on daily life. Traditionally psychometric evaluation is done with parametric methods even if the items are ordinal data. In this study the instrument to be developed is solely based on ordinal data, and the psychometrically evaluation is done with both traditional methods (i.e. parametric statistics) as well as with non-parametric methods. These two different ways of psychometrically evaluation are then compared with each other.
Mätning av tjänstekvalitet i bibliotek: användning av LibQUAL+ i Sverige
The aim of this master thesis is to measure library service quality in two groups of libraries, newly developed and well established, and to see if there are any differences in the users perception of the dimensions in LibQUAL+. The thesis also examines the different perception of quality for the user groups: undergraduate students, graduate students, and faculty. Another approach is to test the Swedish translation of LibQUAL+. Different theories on service quality are presented but the main theories are from the marketing perspective. The grounding and development of LibQUAL+ is described as well as the use of the instrument in different libraries.
Metodjämförelse mellan instrumenten Vitros 5,1 FS och QuikRead CRP för analysen P-CRP
In studies of serum, in the early 1930s, from patients with pneumonia, a factor was found. It could agglutinate certain pneumococcal species. This factor, which later became known as C-reactive protein (CRP), increased sharply during the early and middle stages of the disease. CRP was identified as an acute phase protein and found especially in bacterial infections. CRP is synthesized in the liver by stimulation of interleukin 6 (IL-6), which is produced by the monocytes, and consists of five non-covalently bound subunits.The aim of this study was to compare two different analytical instruments (Vitros 5.1 FS Ortho-Clinical Diagnostics and QuikRead CRP Orion Diagnostica) for CRP analysis.
Perceptuell bedömning av tal och röst hos vuxna med 22q11-deletionssyndrom
Speech anomalies have been described as characteristic symptoms forthe 22q11 deletion syndrome. However, research on speech and voice in adultswith the syndrome is still scarce. Previous research has indicated that speech andvoice anomalies seen in children with the syndrome might have neurologicalcauses. The aim of this study is to investigate speech and voice in a group ofadults diagnosed with the 22q11 deletion syndrome, with extra focus onanomalies with possible neurological cause. The researched group consisted of24 adults between the ages 19 to 38 with a verified 22q11-deletion, 16 womenand 8 men.
Hellre överkvalificerad än undersysselsatt - om övergångsfrekvensen till högre utbildning i Sverige under 80 år
This essay aims to explain the fluctuations in the Swedish transition rate to higher education between 1923 and 2002. With theories of human capital, and screening, as points of departure, seven variables are selected and their correlation with the transition rate investigated by use of graphs and tables. The variables are unemployment, youth unemployment, the supply of academics, cohort size, number of high school graduates from programs preparing for ensuing studies, relative wage trends for worker categories with differing levels of education, and structural phase. Results show that no single variable nor the theories of human capital or screening can explain the fluctuations in transition rate in full. Instead I propose a theoretic model which amalgamates the above and places risk aversion as the driving force behind the individual?s educational decision.
Finansiella instrument ? En studie av inkomna remissvar
Under året 2009 publicerade den internationella organisationen IASB ett internationellt redovisningsregelverk under namnet IFRS for SMEs. Denna självständiga redovisningsstandard komma att ligga till grund för det svenska redovisningsregelverket K3, som är avsett för icke börsnoterade små och medelstora företag som upprättar årsredovisning. BFN började år 2004 med ett nytt arbete med normgivning för icke börsnoterade företag, ett regelverk som kallas K-projektet vars syfte är att förenkla redovisningsarbetet. Samtliga onoterade företag som är bokföringsskyldiga skall innefattas, och beroende på företagets storlek och utformning delas de in i olika kategorier (K1-K4).I september 2010 skickade BFN ut en komplettering av K3 på en redan utskickad remiss. I kompletteringen återfanns det bland annat förslag med kapitel 11 och kapitel 12, som tar upp värderingar och redovisningsprinciper för finansiella instrument.
Förekomst av stress och utbrändhet bland röntgensjuksköterskor
Stress and burnout is a common healthproblem among different workcategories today. The aim of this study was to investigate possible presence of stress and burnout among radiographers and if there was a connection to number of years in the profession. Maslach Burnout Inventory was used as an instrument to investigate the possible presence of burnout, supplemented with questions about stress. The instrument contained a total of 33 questions and was handed out to two hospitals in south of Sweden with a total of 51 respondents. The study showed that the most stressful situations arose due to workload, negative stress, bad working environment and high time pressure.
Kloridhalter i gran utmed en depositionsgradient för havssalter :
The knowledge of the chloride content and its fluxes and patterns in trees is insufficient. Increased knowledge would be desirable, one of many reasons is to be able to more efficiently meet the problems that the substance causes in the pulp industry. The purpose of this study was to examine and describe the chloride concentration of Norwegian spruce (Picea abies L. Karst.) in the south of Sweden. Furthermore the aim was to be able to predict chloride concentration from readily measurable site factors.
Stress: En gransking av studenters stressnivå - Praktik och icke praktik
Practical and theoretical learning are methods that are used in schools as a
way to prepare students for the working life. Within the practical learning
knowledge is not only acquired to learn in practice, but the students must also
be able to apply their theoretical knowledge to what he/she does. Against this
background, the aim of the study was to investigate the importance of practical
learning for students in college / university level and how they are
experiencing the stress that may arise out of the loss of practical learning
during their education, as well as their vision for working life after
completing their education.
The population of the study consisted of N = 36, which 18 of these had used
both practical and theoretical learning and the remainder had only used
theoretical learning. The method was a questionnaire survey with a high
proportion of fixed alternative answers according to likert scales.
IAS 39, finansiella instrument vs dagens rekommendationer: en studie om effekter införandet kan tänkas ge
Allt fler företag blir globala och har internationella kunder. För att öka sina chanser att få finansiering noterar många svenska företag sig på utländska marknadsplatser. Den snabba förändringen av de internationella finansiella marknaderna har medfört en utbredd användning av ett flertal finansiella instrument. Europaparlamentet har godkänt en förordning om tillämpning av IAS, som trädde i kraft i början av juni månad 2002. Förordningen kräver att alla börsnoterade europeiska företag senast 2005 ska upprätta koncernredovisning enligt IAS.
Belastningar i bettet och dess korrelation till hästens rörelsemönster vid körning på rakt spår :
The use of a bit in the mouth of a horse is being increasingly questioned with respect to its actual function, and is sometimes judged an obsolete instrument of control with potential to injure the horse.
The objective of the research presented herein was twofold; firstly, to investigate the actual pressure load in the mouth of the horse with regard to oral health issues, and, secondly, to investigate whether this could be a viable method to objectively measure strength exerted by a rider/driver to the mouth of the horse especially with regard to training regimes.
From the results, it is evident that these newly developed sensors have a future in equine research, although they are still under development. They can be useful both as a pedagogic teaching instrument, providing instructor and pupil with instantaneous, objective feedback on the contact between hand and mouth, as well as an aid in measuring pressure loads from our common bits.

Är jag min röst eller är rösten mitt instrument?: En studie om sångstuderande gymnasieelevers uppfattning om röst och identitet
Syftet med denna studie är att undersöka hur gymnasieelever med huvudinstrumentet sång upplever sambandet mellan röst och identitet. Deras uppfattning av hur sånglektioner påverkar deras utveckling av självförtroende och identitet undersöks också, samt vad de anser kännetecknar en utvecklande sångundervisning. Med hjälp av kvalitativ intervju av sex intervjuobjekt på två olika skolor ges följande resultat: De flesta av eleverna menar att rösten kan vara både ett instrument och en del av personligheten eller identiteten. Det är dock ett mer personligt eller mer kroppsligt instrument än andra. För några elever påverkar deras utveckling av rösten och musikaliteten andra delar av livet, till exempel vilka val av utbildning de tänker göra eller hur självsäkra de är.
