Mass distribution with techniques as multicast and peer-to-peer are becoming increasingly important in the Internet. Today the distribution of sound and video over Internet, so called streaming media, is static due to the unicast method. This results in a linear increase of distribution costs and therefore no conditions for commercial scalability. This thesis describes why multicast may be the only scalable alternative for commercial mass distribution of streaming media over Internet. Mass distribution through peer-to-peer technology promises a lot but is fronting a couple of great challenges, for example asymmetric bandwidth, locality and legalization.

This thesis aims to investigate if peer-groups based on industry classification perform as well as, or better than, peer-groups based on other measures that represent factors affecting the price-to-earnings multiple. In contrast with previous empirical studies, a solid theoretical approach is used in defining which factors, according to valuation theory, affect the P/E-ratio. The factors identified as explanatory are accounting measures, risk and growth. Furthermore, we have recognized several measures that represent these factors. These measures are tested for accuracy of prediction in terms of the P/E-ratio for peer-groups based on these measures relative to an industry classified peer-group.

Abstrakt: Den illegala fildelningen har blivit ett omdiskuterat ämne runt om i världen sedan fildelningstjänsten Napster skapades av unge Shawn Fanning. På senare år har flera nya fildelningstekniker utvecklas och upphovsrättskyddat material delas ut och laddas ner av hundratusentals tals personer runt om i Sverige. Syftet med rapporten är att ge en beskrivning av tekniker och lagar som tillämpas inom illegal fildelning. Samt att beskriva olika aktörer som figurerar inom den illegala fildelningen och vilka åtgärder de tillämpar för att fortsätta och skydda sin verksamhet..

I denna litteraturstudie har synen på konflikthantering och speciellt elevledd konflikthantering belysts ur ett sociokulturellt perspektiv. I forskningen som undersökts belyses flera metoder som baseras på peer mediation, något vars pedagogiska implikationer lyser med sin frånvaro i den svenska skoldebatten. Denna systematiska litteraturstudie belyser internationell forskning kring elevledd konflikhantering och diskuterar sedan detta i relation till det svenska skolsystemet. Efter närmare granskning av internationell forskning kring peer mediation framkommer både risker och positiva resultat. Speciellt i elevers förhållningssätt och långsiktiga strategier till konflikthantering ser vi något som potentiellt kan gynnas av peer mediation..

The aim with this study is to explore if and how linguistic learning takes places when four pairs ofstudents in grade one writes on the computer. Observations of eight students took place duringtwelve lessons to investigate what happened during their writing processes. This study isimportant because students? computer writing is a relatively new phenomenon in the Swedishprimary school.It is clear that the peer collaboration creates a complex interaction that becomes the platform, andalso the prerequisite, for successful language training. The method can clearly give students profitsin their linguistic development.

AimThe aim of the study is to gain insight into how physical education teachers reflect on peerassessment in Physical Education (PE). The study was limited to investigate teachers? conception of peer assessment. The study also examines whether teachers can describe anymethods of peer assessment that they use or have used in their teaching, and what strategic choices they talk about when they describe their methods.MethodQualitative interviews were used to collect data. The interviews can be referred to as in-depthinterviews with a particular focus on concepts.

The purpose with this study was to find out about the preschool toddler?s peer-cultures. I also wanted to understand how these peer-cultures were shown.My questions are as following:What is it that the children interpretive and reproduce in their play?How do children gain access to play?How do children exclude each other?What position of status can be seen in children´s play?I used observations as the method to find the answer to these questions. These observations where implemented during five occasions at two different preschools.

This paper studies how peer assessment is used as a strategy to improve young learners' results in Swedish as a school subject. Nine teachers are interviewed about their use of the method on 7-12-year-old pupils. Comparisons are made between the interviews and Swedish and international discussion on peer assessment. There are similarities between the practice of the teachers and what is said in the litterature about the method and its advantages and drawbacks. The teachers tend to emphasize the social aspects more, though.

In my thesis, I set out to study academic peer reviews in the hope of clarifying the experts? views on what qualities and qualifications are desirable when appointing or promoting scholars within History of Science. I also investigate whether or not these views change over the years, as I have studied opinions written between 1980 and 2010. I use a qualitative method of analysis, in which I study what words in the peer reviews are used to describe certain values, and how these words relate to the historical and political background of History of Science in Sweden. My research indicates that academic experts are starting to adapt their opinions to the change in educational politics that has taken place during the second half of the 20th century.

The aim of this thesis was to investigate how teachers in school and in leisure time center look at informal and formal learning. Informal learning is often associated with leisure-time while formal learning is generally linked to school. My questions also deal with the teachers? view of each other?s activities from a learning perspective and visibility of informal learning. I have made an empirical study with qualitative, semi-structured interviews with three class teachers and three leisure teachers.

Problemområde: Idag är användandet av peer-to-peer (P2P) - applikationer såsom KaZaa, ICQ och Seti@home utbrett bland privatpersoner. Användningen inom företag är dock ännu i sin linda. Vi kommer därför i den här uppsatsen utreda om ett eventuellt införande av P2P- teknik i ett företagsnätverk ger några fördelar jämfört med en klassisk Client/Server-lösning. Hypotes: Arbetet bygger på hypotesen: ?En P2P-lösning ger fördelar för företaget jämfört med en Client/Server-lösning? Genomförande: För jämförelsen mellan P2P och Client/Server definierades och jämfördes fem områden: Säkerhet, Användbarhet, Tillgänglighet, Bandbredd samt Utrustningskrav.

In this study we aim to investigate what employees at a callcenter see as prospects, opportunities and barriers of learning within a company. To answer the purpose of this essay, two questions were formulated; "What opportunities for learning does employees experience in the company?" and "How can learning in the workplace improve for the sellers?". First, we present what previous research has highlighted regarding workplace learning and learning within the callcenter industry. Afterwards we present ten semi-structured interviews with leaders and sellers within a telecom company in Stockholm.

AbstractIn this essay, I have performed a study on peer cultures and how these peer cultures are expressed in a group of pre-school children. My questions are as following:What positions/power positions can be seen in children?s play, and how will these be expressed?How do the children gain access to play?How do children act when they want to exclude other children?In order to understand this I have chosen to do observations as a method. In order to investigate these questions I chose to spend six whole mornings with a group of pre-school children, closely observing their behavior. The focus was on children, three years of age or older.

The chief aim of this study is to investigate the impact of context on written peer response. A second aim is to explore students? attitudes towards peer response. The investigation has taken place at an upper secondary school in the south-east of Sweden, involving 20 students in grade 2 and 3 in the course Swedish C. The investigation is based on the students? comments on their peers? speech drafts and six qualitative interviews.
