P/E-talseffekten : Myt eller verklighet
Bakgrund: Finns det verkligen en investeringsstrategi som ger en garanterad överavkastning och som skulle kunna innebära att efterfrågan på de tjänster som professionella kapitalförvaltare tillhandahåller försvinner?Syfte: Syftet med vår uppsats är att undersöka huruvida det går att generera överavkastning på Stockholmsbörsen genom att investera i en portfölj enbart innehållande aktier med låga P/Etal. Frågan är alltså om det existerar det någon så kallad P/E-talseffekt?Genomförande: P/E-talseffekten testades genom att vi för var och en av våra 28 perioder fr.o.m. 1991 t.o.m.2004 skapade två portföljer där den ena innehöll aktier med de femton lägsta P/E-talen på Stockholmsbörsen och den andra innehöll aktier med höga P/E-tal.
Beräkning av direktljud genom homogena betongväggar : Densitetens och tjocklekens påverkan på reduktionstalet
Today's urban centers become denser, which contributes to higher demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. Handmade calculations were calculated according to the Swedish standard SS-EN 21354-1, where only air sound was calculated.Calculations were performed on wall elements with different weights and thicknesses, and compared with results from Bastian.In Bastian calculations of flanking transmissions were also made, this was made to see the impact of the flanking transmission when changing the mass per unit area. Mass law's impact was examined by flanking transmission and the result shows that they are not affected as long as the ratio between the thickness and the density remains the same.A questionnaire survey was conducted to determine the actual sound experience; this questionnaire was conducted on three concrete buildings in Växjö.
Likheter och skillnader i kommuners verksamhetsstyrning : en jämförande fallstudie mellan tre kommuner
Problem-formulering: Hur fungerar ekonomi- och verksamhetsstyrningen inom den kommunala verksamheten? Hur sätter kommuner mål och hur följs de upp? Är sättet att fastställa mål och mätmetoder likartade eller finns det skillnader?Syfte: Syftet med uppsatsen är att studera hur kommunerna Gnesta, Nykvarn och Salem styr sina verksamheter via uppsatta mål och hur de följer upp dem ur ett ekonomiskt- och verksamhetsperspektiv.Metod: En fallstudie har gjorts vid tre kommuner.

Vidare presenteras de undersökta kommunernas sätt att styra sina verksamheter.Slutsats: Kommuner uppvisar både likheter och skillnader i sina sätt att fastställa mål och mätmetoder.
Barns delaktighet och inflytande i den pedagogiska dokumentationen i förskolan
The purpose of this study is to find out what the educators idea of educational documentations in ratio to childrens inclusion and impact in pre-school are, together with the child's own perception of the concepts of documentation. We proceeded from the following issues: What are the significance of educational work according to the teachers? What is the teachers idea of a childs impact and inclusion in educational documentation? In what way do the children have influence over, and inclusion in educational documentation? What are the childrens feelings of the documentations? In order to find answers to our questions, we used qualitative examinations consisting of seven educators and seven children from various pre-schools in Stockholm, and thereby, we have analyzed our results. As our theoretical frame, we used ourselves of Vygotskijs and Säljö's sociocultural perspective that is about "progress and learning", which is achieved by interaction and cooperation in a social context. The result shows that the aim of educational documentation is to reveal the childs development and learning, and also to involve the parents by putting up documents on the wall.
Läsa ljud : Att formulera en texts auditiva kvaliteter visuellt
In printed text, sound is a somewhat forgotten aspect. The recitation of text is vital in areas like poetry and oratory, but still has no distinct technique of being communicated. Emphasis of a word might be expressed through italics, but no canonic character set or system for vocal delivery of texts exists. With this essay we are creating a foundation for a development of such a character set or system. By studying existing visualisations of sound and comparing these with semiotic and perception-based theories we obtain useful insights for a prospective system for visualisations of vocal sounds.We conclude that the aspects of sound one wants to visualise must be carefully defined since the viewer cannot process infinite amounts of information.
Postoperativ smärta hos yngre barn. En litteraturstudie om sjuksköterskans förmåga att tolka.
The purpose of this literature review was to demonstrate the results of recent studies of the nurses ability to interpret younger childrens (0-6 years of age) experiences of pain in the postoperative stage. There is a lack of knowledge concerning young childrens ability to express themselves verbally and the nurse has to rely upon the parents knowledge about the child. Consequently, the teamwork between the nurse and the parents is of great importance in the care of the younger child. Therefore we intend to illuminate this aspect in this paper. This study aims to nurses of all categories, since patients with lack of verbal communication are frequently occurring.
Tjejgrupp - stärkande eller problematiskt kollektiv? : En analys av erfarenheter och minnen från feministiska tjejgrupper
This essay investigates the results of participation by teenage girls in feminist groups, the so called girl groups. These groups are descendants of the awareness-raising groups of the 1970?s feminist movement. The essay assumes the relevance of theories of heteronormativity and performativity, as well as theories surrounding two different ways to organize girl groups. It is done either through the Pippi-feminism, named after strong independent book character Pippi Longstocking, or through the collective empowerment feminism.
Att odla stärkelsevete åt SBI-Trading
Då giraffens föda utgörs endast av blad, löv och knoppar, trots att det är den största idisslaren som lever idag, har dess anatomi genomgått en serie av anpassningar för att kunna överleva på denna föda. Till det yttre har den under evolutionens gång utvecklat en otrolig längd som gör att den når långt upp över alla andra idisslare, och till det inre har dess mag-tarmsystem anpassat sig efter födans egenskaper. Giraffens huvud har en avlång form och behåring på läpparna som ska skydda den från trädens stickiga försvar, en tunga som kan bli upp till en halvmeter lång, och tuggmuskler som har anpassats till den relativt lättuggade maten. Förmagarna har i sin tur minskat i storlek och kraft och fått ett anpassat utseende och utbredning på dess papiller, och tarmen har en liten ratio tunn/tjocktarm.
Giraffens cirkulation har fått anpassa sig till stora höjdskillnader, då giraffen kan sträcka sig upp till ett träd och bli mer än fyra meter lång, men i nästa stund böja sig ner för att dricka vatten på marknivå. Som följd av dess längd har dräktiga och lakterande honor, samt växande ungdjur, en väldigt hög kalcium- och fosfatomsättning i kroppen och kan därför lida brist på dessa mineraler.
Den drivande kraften bakom giraffens längdutveckling har länge sagts vara övertaget den ger vid födosök, men det finns även en annan teori som baserar sig på att den drivits av sexuell evolution..
En tand för en tand och en våtmark för en våtmark - ett återskapande värt pengarna? : En undersökning av nyttan och kostnaderna av att restaurera våtmark med hjälp av Contingent Valuation Method.
The goal of this study is to examine what five teacher?s impression of the teacher?s role is in their previous years. How important the ?joy at work? is in relation with the educational progress? And what aspects that contributes to the? joy at work? and what obstacles that stops them. The essay will also go through the concepts of a teacher role, with connection to the theoretical perspectives of Csikszentmihalyi?s Flow and Antonovsky?s Salutogenesis (KASAM).The method I used was interviewing five teachers and I used Larsen?s chapter of ?content analysis? as a basis, I also used Flow and KASAM as theoretical references in my analysis.
En studie i att tillämpa Computational Thinking på grafteori
Computational thinking was brought to the forefront in 2006 by Jeannette Wing. Computational thinking is a problem solving method that uses computer science techniques.The thesis is analyzing computational thinking and how it could be applied to graph theory. Characteristics and main fields from computational thinking is being analysed. This analysis is applied to graph theory to see the potential in developing a proposal for how an exercise can look for an introductory course in discrete data types. Only basic knowledge of graphs is required to perform the exercise.
Socialtjänstens Vårdnadsutredningar : En rättsociologisk undersökning om Socialtjänstens utredningar och rättstillämpningen i vårdnadstvister.
The aim of this study is to look how the Social Service has handled custody issues.

During a period of one year a quantitative and qualitative study was performed within the social administration in a nearby community. The study focus is partly on the relationship between the law, family and society. The main questions have been: Which one of the parents, mother or father, did in fact get the custody and why? How has the children?s point of view been reported in the inquiry? A child needs a well organized everyday life in a preferably conflict free environment.
Stegvis förändring för demokratisering i Kina-en möjlighet?
The aim of this essay is to investigate the situation for democracy in China. The study raises two main questions. They are as follows: Are there obstacles to a democratization process in China? and Are there openings when it comes to a gradual change for democratization in China? The theoretical framework consists of Robert A.Dahl´s Polyarchy theory, and in addition , five factors promoting democracy. Also the notion of an MDP-society (a modern, dynamic and pluralistic society) is looked upon.
Simulerat kreativt resonemang i matematikföreläsningar
Empirical research shows that a possible reason why Swedish students mathematical knowledge deteriorates can be a too big focus on imitative reasoning, i.e. recalling solutions or follow algorithms, and a lack of creative mathematical reasoning, i.e. when a student construct his/her own solution and motivates its plausibility with mathematically well-founded arguments. The purpose of this study is therefore to examine if, and in what way, lecturers can provide students an opportunity to learn creative reasoning by simulating creativity in their presentations of examples. Six lectures were observed and 22 task situations were analyzed with respect to three aspects; reflection, plausibility and mathematical foundation, which are to be present in the situation if the reasoning will be seen as simulated creative.
?Jag är hemlös, inte lealös?: En undersökning om hemlösas informationsbehov
The aim of this Master?s thesis is to study the information needs of the homeless. The main focus is to investigate what kind of information needs that are to be found among the homeless and also how information is exchanged and shared by the group. Another aspect of our study includes the sources that are used to fulfil these information needs. The homeless use of the library, as one of these sources, is also examined.
