Svenska som andraspråk : En kvalitativ studie av utformningen av undervisningen inom andraspråksinlärning
The purpose of this qualitative study is to understand and examine the problem andreason why second language pupils have difficulties reaching the goals of thecurriculum in ?Swedish as a second language?. The study is based on interviews withtwo second language teachers and Vygotskijs and Antonovskys theories. The interviewswith teachers gave a broader view on why these difficulties exist and whatconsequences might occur. This analysis shows that there can be different reasons as towhy pupils can not reach the goals in their second language that are set for them.
Mata inte trollen : En studie i marknadskommunikation och internetkultur
Social media provides, as many points out, new possibilities for marketing. Marketing in social media requires a two way communication, rather than the traditional marketing where the communication model is typically sender ? receiver.To create a marketing campaign that is suitable for a two way communication model has its difficulties and risks as well as its opportunities. Opportunities in the sense that the campaign can become a viral, a Word of mouth and create a Buzz, which will reach potential customers, to a bigger quantity for lower costs, with a message that will make a different impact from the types of commercial messages we are used to. Risks in the sense that the message, if not properly aimed and phrased, can be turned overnight into something that humiliates the company and possibly harm its brand.The difficulties in creating such a campaign is to create something that will catch people?s attention, discuss and forward it, while at the same time avoid getting hurt.We aim to describe the internet from a cultural context, and from that point of view explore the types of misunderstandings which often seem to happen when a corporate message is created and sent out in social media, how to avoid putting the image of a company in danger when doing this, and examine if there is ways to know how the message will be received.
"De har ingen självklar plats någonstans" : - En studie om socialarbetares erfarenheter av multiproblematiken kring insatser och insatsbehov till våldsutsatta kvinnor med missbruksproblematik
Previous research shows that women who are victims of intimate partner violence and also have asubstance abuse have difficulties getting access to services to aid with their experience of violence.This study has examined social workers experiences of working with women with these problems,what types of services are provided and how their service needs are assessed. The study has ahermeneutical approach and the data consists of interviews with nine social workers in lines ofwork that come into contact with women in the previously described client group. The data hasbeen analyzed using content analysis. The result of the study indicates that women who are victimsof intimate partner violence and also have a substance abuse do not get their needs provided forthrough the current services in the field of social work. These women are described as havingcomplex problems and are therefore in need of more and other services than those currentlyprovided.
Energieffektivisering av linjesjöfarten till och från Tasmanien
Tasmania is a state in Australia, and is also the country?s largest island. It is separated from the main land by a 429 kilometer wide strait. Every year, a large amount of people, cars and goods are transported to the island using a government owned ferry line, which generates approximately 300 million Australian dollars to the state?s economy ,every year. This bachelor thesis investigates the possibility of reducing the fuel consumption for the ferry traffic to and from Tasmania, which would also reduce the overall cost.
Hedersrelaterat våld kombinerat med annan problematik - Om eventuella samband mellan utsatthet för hedersrelaterat våld och utvecklandet av psykisk ohälsa och/eller en missbruksproblematik
The purpose of this essay is to explore how social workers view a possible connection between exposure to honour violence and development of mental illness and/or substance abuse. We first heard of the possible connection from a voluntary organization who work in this field and who believe that this connection could be common. We therefore wanted to explore this from the perspective of social workers who come into contact with victims of honour violence: was this something they had noticed? How did they deal with it if it was noticed? We also asked how the possible connection could be interpreted and, supposing the social workers had failed to notice the connection, why this could be. We made five qualitative interviews with six social workers working in different contexts whom within their work come across honour-related issues.
Matematik i förskolan : Barns antalsuppfattning i de tidiga åren
Purpose: The current thesis assignment aims to explain, understand and follow the strategies the young children employ into a conception of numbers. This thesis is based on a study performed by Doverborg and Pramling Samuelson.The following research questions serve to refine the stated goal:How mathematical thinking regarding conception of numbers occurs within younger children and which strategies they use?How is the interaction between the teacher and the younger children?Method: The study is organized as a qualitative study and was conducted in a pre-school with a group of four children. The children that have participated within my study are between two and three years old. They were filmed in four exercises.
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).
Narrativ förmåga vid afasi : analys av strategier vid gemensamt berättande
Aphasia is a linguistic impairment which affects communication and may have an impact on a person?s narrative ability. The purpose of the present study was to analyse the narrative ability in aphasia by narrative interviews with people with aphasia and their partners. The interviews were scrutinised for strategies used in joint narration involving couples where one of the spouses has aphasia. The definition of strategies was methods to cope with communicative difficulties often due to aphasia.
Det nya Gustavsvik : -En studie av förnyelsen av en attraktion
Studies show that some pupils with ASD (autism spectrum disorder) can have difficulties in understanding written texts. The present study seeks to examine whether pupils with ASD differ in their reading comprehension of a factual text and a literary text. Another aim of the study is to obtain a picture of the reading habits of high school pupils with ASD, what reading strategies they use, and how they work with texts in Swedish lessons in school.The study uses texts from PISA surveys from 2009 and 2000. The factual text Varmluftsballongen (The Hot-air Balloon) was taken from the try-out for the 2009 survey and the literary text Gåvan (The Gift) was taken from the 2000 PISA survey. To gain some idea of the pupils? reading comprehension of the texts, the present study used the tasks accompanying the texts, with certain changes in the questions about the text on the hot-air balloon.

In addition to interviews, I have conducted observations at each preschool. The different preschools are one traditional, one Reggio Emilia and one ?all weather? (Friluftsfrämjandet) preschool.
Feldetektering för diagnos med differentialgeometriska metoder -en implementering i Mathematica
Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.

Research question: What effects on the consultants? effort direction do the staffing managers expect of the formal or informal incentive system? Method: The authors have found that a suitable method for the thesis is a survey study.
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..
Förståelse för och attityder till matematik
Studiens syfte är dels att undersöka vilken förståelse för matematik ur ett samhällsperspektiv som elever på en mellansvensk kommunal gymnasieskola har, utifrån den beskrivning av ämnet som finns i de svenska styrdokumenten. Syftet är också att undersöka vilken inställning till ämnet eleverna har, hur attityden påverkas av vänner och familj, samt vilken betydelse media har i synen på matematik.Studien bygger på en enkätundersökning där 130 respondenters svar har behandlats. Genomgående i analysen har gruppen med elever som läser ett yrkesinriktat program jämförts med de elever som studerar på ett mer teoretiskt inriktat program.Resulatet visar att elevernas förståelse för matematikens roll i samhället är fullt acceptabel, men att det är få som nått ett fördjuad insikt. En klar majoritet anser att de förstår syftet med matematikundervisningen.Trots att en dryg trejedel tycker att matematik är det viktigaste ämnet så finner cirka hälften inget intresse för ämnet. En sjundedel säger sig t.o.m.
Undersökning av ackommodationsförmåga och brytningsfel hos varmblodiga travare :
Skiascopy is used to objectively determine the refractive power of the eye. Except for a Swedish study in 2007, where 93 horses of different breeds and ages were examined with respect to their refractive status, most studies on equine refraction were published about one century ago or more. The objective of this study is to examine the refractive status of healthy warm-blooded trotting horses.
Skiascopy was performed in 117 horses in total, aged 3 days to approximately 22 years old. In a pilot study, it was determined whether young horses were able to accommodate or not during skiascopy. The horses in the pilot study were all younger than 14 months.
In foals younger than 1,5 months we saw a significant difference in the skiascopy result in the right eyes before and after topical atropine was instilled, but not in the left eye.
