Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem
This Masters thesis work describes a comparison between two different methods
for estimation of the down channel (base station to mobile subscriber) in
Wide-band Code Division Multiple Access (WCDMA).
The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is
a conventional method that bases the estimates on data that is known to both
sender and receiver, so called pilots. The second method, Decision Directed
Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data
for estimation.
Simulations show that DDCE, in comparison to OFCE, does not attain an
improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An
improvement is only seen when the BER becomes much lower than what is common in
real situations.
In conclusion DDCE is complicated, involves many mathematical operations and
gives insignificant improvement of SNR when BER takes common values. It is
legitimate to question if it is possible to use the method in a real mobile
phone system..
Evidens eller referens?: vad påverkar rektorers beslut?
Today the school is a given place for preventing social problems. The school struggles continuously to live up to the expectations of balancing preventive social work with pedagogy in a satisfactory way.The purpose of this essay is to get a picture of priorities of social work in school. I want to know what it is that affects and controls the principal's decision about what kind of social project they will accept and be a part of.This essay shows that only one of the eleven principals interviewed apply projects based on evidence when they decide about participation in a social project. Instead, the decisions are based on references from other schools. The reason why the principals do not base their judgement on projects which are based on evidence is because they consider the search for results too time consuming.When there is no requirement that a certain part of the social work in a school must be based on evidence, it leads to the children taking part in different social projects which we can not guarantee are good for them.One solution can be to guide the principals through a national social teachingplan, which can assure that social work based on evidence are being applied in the municipality schools as well as the independent schools..

The Beautiful Boy, The Destroyer : Sexradikalers förhandlingar om tidskriften Destroyer ? en intervjustudie om anständiga bögar, fula gubbar och sexualiserade barn
Through the collection and analysis of negotiations surrounding the gay magazine Destroyer, the intention of this paper is to identify norms of sexuality within a contemporary sex-radical discourse. These negotiations are collected from interviews with individuals whom, at the time of the inter-view, consider themselves or their politics sex-radical. In order to allow for a more general under-standing of the context in which these negotiations have come about, material about Swedish law is also included in this text, together with the interview material, and serves as a base for analysis through the application of Gayle Rubin?s theory on the hierarchical value system of sexuality.Following, are the main themes throughout the paper: The meaning of the context; Sexualized children; The possibility to (not) participate: differences of power; The decision whether or not to sell the publication and The position of the pedophile and crossgenerational love/sexuality within the LGBTQ community.Key words: sex radicalism, pornography, boy-love, kiddy porn, pedophilia, Destroyer, Gayle Rubin..

Fysisk bestraffning i Sydafrikanska skolor : En perspektivorienterad hermeneutisk analys kring läraresoch elevers förhållningssätt till fysisk bestraffning
The purpose of this paper is to explore how masculinity and femininity are constructed in the magazine Veckorevyn, through a critical discourse analysis of 18 articles from six issues in 2011. This is done by using a variety of theories and previous research results, which is gender theory, the theory of late-modern society and media theory. The analysis shows that Veckorevyn depicts virility and feminine differently. Furthermore, pointing the results from the analysis that a change of manhood and womanhood takes place in the social practice.

Hur sjuksköterskor kan handla i situationer där personer med demenssjukdom inte äter, samt hur de motiverar sitt handlande : - en litteraturstudie
Syfte: Studiens syfte var att jämföra en ny extubationsalgoritm med sedvanligtextubationsförfarande. Gruppen som studerades var patienter som genomgått en HIPEC-operationoch vårdats på Centrala intensivvårdsavdelningen.Metod: I En randomiserad kontrollerad klinisk pilotstudie randomiserades patienterna till en av tvågrupper. Därefter extuberades patienten enligt en studiealgoritm eller post-operativ standard.Resultat: Syresättningen var väsentligen oförändrad för studiegruppen (37,5 kPa till 36,6 kPa)medan den sjönk för kontrollgruppen (50,1 kPa till 40,6 kPa) vid jämförelse mellan 10 minuter efterankomst och 15 minuter efter extubation. Efter 13 till 18 timmars kontroll strax innan patienternalämnade intensivvårdsavdelningen var syresättningen på samma nivå som 15 minuter efterextubation för både studiegruppen och kontrollgrupp. Således kvarstod en försämrad syresättninghos kontrollgruppen vid utskrivning jämfört med 10 minuter efter ankomst.Slutsats: Studien visar att det skulle kunna vara fördelaktigt att extubera patienter enligt denstudiealgoritm som testats jämfört med dagens kliniska standard.
Att skapa en motkultur : En religionspsykologisk undersökning av Livets Ord som religiös minoritet i en sekulär kulturell kontext
In this textual analysis I have examined the book Att följa Jesus by Ulf Ekman and information from Word of Life's official website. The aim of this study is to see how a religious leader is shaping the identity of the groups members after a certain pattern that differs from the surrounding, secular society. The research focus of this essay includes several aspects: how a culture is formed in a religious minority in contrast to the prevailing cultural context; how the material can be explained by Paul Pruyser?s theory on the psychological worlds; how what Ulf Ekman writes about distinguishing themselves from the environment differs from how other religious minority groups distinguish their identity; and, how the psychological world, expected behavior, and context of Word of Life can be structured by Valerie DeMarinis? model of assessment. I have placed Word of Life in a realistic illusionistic world developed from Paul Pruyser?s theory of psychological worlds.
Arbetsmotivationens betydelse för engagemanget i en organisationsförändring
The purpose of this study was to examine the relation between self-determination theory and its three basic needs: competence, autonomy and relatedness, and commitment to change in an organizational change. Another purpose was to examine if the quality of the communication and the effects on the organization and way to work can predict commitment to change. Considering that organizational changes is very common today there is an interest to ease and improve the change process. The survey contained the scales Commitment to change scale and Basic need satisfaction at work scale and the participants were 39 office-workers who recently had gone through an organizational change. The result indicated that it?s possible to predict commitment to change from self-determination theory, communication and effects on organization and way to work.
Grundsärskolan- en skolform i tiden? : Grundsärskolans personals uppfattning om uppdrag, synsätt och attityder
The Swedish government ratified on May 1 2009 an amendment of marital law, resulting in same-sex marriage becoming legalized. With the rights of the Christian Swedish state church to officiate weddings originating from the same law, the church was thereby faced with two options: Either officially include same-sex couples in the Christian concept of holy matrimony and keep the right to officiate weddings; or give up the right to officiate weddings altogether. An official decision to accept the terms was reached on October 22 2009, but not without being preceded by an agitated medial debate.This research attempts to analyze the arguments of the debate in three stages: In the first stage the arguments are categorized according to their respective ideological standpoint. In the second stage these categories are examined from post-modern, social constructivist and socialization theory perspectives. Based on this, the third stage sees the arguments analyzed from a viewpoint based in the Copenhagen school concept of securization.The research concludes that the debate does not only simply feature two sides with differences of opinion; but rather that the arguments of the two opposing sides are founded in a common view of the other side as a fundamental threat to ones conception of a sound society..
Pluralismens utmaningar - En teoriprövande studie med Belgien och Schweiz.
This thesis is set out as a testing of the crosscutting cleavages theory on twocontemporary cases. The aim is to test the explanation process of the crosscutting theory applied to the political and social situations in Belgium and Switzerland and furthermore to examine potential conflicts in pluralistic states. Our main questionis: How can the crosscutting cleavages theory explain the different outcomes ofsocial coexistence, even with the states numerous similarities? We have examined the two federal states through their social divisions of language, region, religion and socio-economy. Our findings show that both Belgium and Switzerland possess divisions in the above mentioned variables, which in most cases are cumulative structured.
Prehospital bedömning: En forskningsöversikt
Patienter utsätts för onödiga transporter och efterföljande väntetid på akutmottagningen, vilket i sin tur leder till ett onödigt vårdlidande. Det är inte längre en självklar åtgärd för ambulanssjukvården att transportera alla patienter till akutmottagningen för fortsatt vård. Detta innebär att kravet har ökat på ambulanssjukvården och den prehospitala bedömningen. Mot bakgrund av dessa förutsättningar som idag gäller för ambulanssjukvård, är frågan om forskningen kan vägleda till hur den prehospitala bedömningen ska kunna underlättas.Syftet med studien är att beskriva prehospital bedömning i ambulanssjukvård och genom en forskningsöversikt har kvalitativ och kvantitativ forskning analyserats.I resultatet framkommer det att prehospital bedömning består av två huvudinnehåll, dels en vårdvetenskaplig där den prehospitala bedömningen ses som en kontinuerlig process och dels en medicinsk där den prehospitala bedömningen inriktas på att utifrån fastställda kriterier ringa in patientens vårdbehov. I den vårdvetenskapliga forskningen framkommer att vårdrelationen är en central del i den prehospitala bedömningen liksom att vinna patientens förtroende.
Kommunikationen i miljökonsekvensbeskrivningsprocessen : en intervjustudie om infrastrukturprojekt
Communication during the process of Environmental Impact Assessment:
Interviews concerning three infrastructure projects
Environmental Impact Assessment (EIA) is a method to describe the possible impact of a planned project. The aim of such an assessment is to aid a sustainable development, by supplying a comprehensive basis for decision-making. Today there are many people working with EIA in different forms, representing both different interests within the community, as well as having different individual points of view. The proponent is responsible for the EIA, but it is of interest to study the relationship between the different participants who are involved in this process. The aim of this report is to study how the different disciplines involved have communicated with each other and amongst themselves, what characterises good communication, and if anything should be improved.
Statistiska metoder för härledning av indata till säkerhetsanalyser inom kärnkraftsområdet
Objective: In recent years there has been an increasing interest within the clinical (medical) science in measuring people?s health. When estimating quality of life, present practise is to use the EQ-5D questionnaire and an index which weighs the different questions. The question is what happens if the individuals estimate there own health, would it differ from the public preferences? The aim is to make a new prediction model based on the opinion of patients and compare it to the present model based on public preferences.Method: A sample of 362 patients with unstable coronary artery disease from the Frisc II trial, valued their quality of life in the acute phase and after 3, 6 and 12 months.
