Bluetooth and security
Detta arbete behandlar hur Bluetooth fungerar samt säkerheten kring Bluetooth
och några allmänt tillgängliga attack verktyg.
Syftet med uppsatsen är att försöka fastställa hur säkert Bluetooth är i dagens
läge. Bluetooth har länge varit tillgängligt för att utbyta data över korta
avstånd. Därför har man valt att implementera det i kommunikationsenheter som
mobiltelefoner och laptops med mera. Det har funnits en debatt om hur säkert
Bluetooth är. För att kunna genomföra denna undersökning så har vi satt oss in
i hur Bluetooth fungerar, vilka allmänt tillgängliga attacker och
implementationer av dessa, som finns.
Demokrati och diskurs. En normativ analys av diskursiv påverkan på de demokratiska värdena öppenhet, ansvarsutkrävande och inflytande
The idea that I put forward in this thesis concerns the democratic system and the threat from discoursive impact on its core values. I focus my normative analysis on three of these democratic values: transparency, accountability and influence ? and what democratic problems the discoursive impact causes in conflict with them. I have used a critical discourse theory to define discourse and discoursive impact, by focusing on the process of discourse, rather than its nature. I deal with the political structure where I claim that the essential relation between citizen and politician is disrupted, due to lack of information and the imminent problems of the existing network society.
Storjuktan ? Rekonstruktion av ett sekels kvicksilverbelastning. : En undersökning av kvicksilverkoncentrationer i daterat bottensediment.
The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.
Behöver vi en förändring? : olika perspektiv på hållbart jordbruk
Debatten om ekologisk kontra konventionell odling har blossat upp allt mer, förespråkare från båda synsätt har sagt sitt genom slagfärdiga debattartiklar och diskussionen har sedan fortsatt vid middagsborden runt om i landet.
Denna kandidatuppsats i ämnet landsbygdsutveckling syftar till att undersöka vilka drivkrafter som kan ligga bakom olika aktörers engagemang i jordbruksfrågor och hur de ser på vad som är en hållbar livsmedelsproduktion. Uppsatsen syftar även till att utforska hur informanterna framställer sig själva och andra aktörer i debatten som förts kring ekologisk kontra konventionell odling.
Vem bär enligt informanterna ansvaret för jordbrukets utveckling? Behövs en radikal omställning i hela livsmedelsproduktionen för att nå mer hållbarhet eller räcker det med att enbart göra små justeringar? Det empiriska materialet består till största del av fyra informanters syn på dessa och liknande frågor. Detta material har sedan analyserats med inspiration från Erving Goffmans teori om intryckskontroll och Ulrich Becks teori om risksamhället..

Smarta Hus: Nya behov och lösningar med participativ design
In this Bachelor Thesis (20 p.), we present the history and development of
"Intelligent Houses", and most important- explore some of the future
possibilities in this area.
The project has been carried out through an interdisciplinary cooperation
between three different educations at the Blekinge Institute of Technology.
By conducting a dialogue with various actors with different professions, we
have been trying to identify needs within the concept of "Intelligent Houses",
were the end user is not only the tenant or homeowner.
Through Participatory Design methods, such as a Future Workshop, we have
brought the users together to discuss their own and each others needs and
hindrances in their respective work practice, and how intelligent house
technology could improve their work conditions.
We have also been testing a highly sophisticated
CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally
developed for regulating indoor climate systems.
Based on the needs we have found in our fieldwork, we have been looking at
possibilities to make multi user solutions with the sensor..
Speciallärare eller specialpedagog? En studie om speciallärares/specialpedagogers syn på sin utbildning och yrkesroll inom särskolan
In 1990 the education training program for teachers working with children with special needs was changed. One major difference in the new program compared with the former one is that the specialized teacher is now mainly supposed to supervise teachers instead of teaching pupils who have learning difficulties. The aim of this qualitative interview study has been to find out what the specialized teachers think about there education, and how this could influence children with cognitive disabilities in special schools. I have interviewed six teachers who specialized in teaching pupils with cognitive disabilities. Three of them where educated prior to 1990 and the others were educated after 1990.
Grön Flagg : En kvalitativ studie kring barns delaktighet i de tre dimensionerna i hållbar utveckling
It is important to work with economic, social and ecological dimensions in order to reach sustainable development. Furthermore, these dimensions are supposed to work opon together. Green Flag´s aim is to process these dimensions in the thematic work in preschool, where children are involved. The aim of this study is to find out how certificated Green flag preschools work with the three dimensions in the education of sustainable development practically and how the children participate in this work. I have used a qualitative semi-structured interview to find out preschool teachers´ thoughts and opinions about how they work with sustainable development and how they make the children involved.
?Att få fler att upptäcka det fantastiska med läsning? - Möjligheter och hinder för samarbete mellan bibliotekarier och bokbloggare
The aim of this bachelor thesis is to find out the possibilities for librarians and book bloggers to collaborate. We find this relevant because of blogs being a new medium that could be useful for librarians to embrace. Book blogs are often networks of blogs connected to each other through their common interest in literature and we have examined how this could be of use for librarians.The method we have used is semi-structured interviews, which gave us the possibility to adjust our questions based on the informants? answers, when necessary. Our informants have been both librarians and book bloggers; we have met some of them and interviewed the others by e-mail.
Managing urban development : A case study of urban forest?s sense ofplace in Hammarbyskogen, Stockholm
Due to the growing population in Stockholm, some of the urban green areas are beingsubjected to exploitation. Hammarbyskogen is an urban forest in the south of Stockholm andis an example of a green area that is planned to be transformed into an urban environment.This paper investigates key qualities and values of an urban forest of Hammarbyskogenvalued by local inhabitants of the neighbourhoods of Hammarbyhöjden and Björkhagen in thesouth of Stockholm. In addition to that, the study seeks to investigate people?s perception ofthe planned development of the forest as well as investigate how these perceptions andqualities are being incorporated into the process of neighbourhood development.Using text analysis, interviews and discussion forums, findings have been made showing thatthe local inhabitants value the urban forest mostly for its ecological and recreational qualities.Regarding perception of the change, people are either positive or negative to the developmentwhich can be explained by people?s experienced sense of place and place attachment of thearea and the forest itself. The study has also shown that the urban planners rely on localinhabitants? view, as well as on expert knowledge during the process of planning.The results of the study contributes to a better understanding of why and for what purposesurban forests are important for the city dwellers..
Icke-triviala billigaste väg-ruttningskonflikter - klassificering och sökmetoder
Within telecommunication and routing of tra?c in IP-networks a protocol named?Open Shortest Path First? (OSPF) is widely used. This means that a server dealswith the routing over a network with given weights by calculating shortest paths touse for routing. If we assume that a desired tra?c pattern is given the problem isto ?nd out if it is possible to set the weights so that the desired tra?c pattern is apart of a shortest path graph.
En resa till företagets medelpunkt : - en studie av kompetens på mellanchefsnivå
The profit a company makes is dependant of its employees which means that their competence is important for the company to perform well. The middle manager has a central position in the organization and is expected to take on different roles. This probably puts a lot of demands on the middle managers and their competence. We want to contribute with a comprehension of how learning, competence and needs for competence can look at a middle management level. Furthermore we also want to find out what kind of strategy for competence development the middle managers want the company to use so their competence development can be facilitated.

Kampen mot kedjorna : En kvalitativ studie om hur en enskild, nischad klädesbutik utmärker sig genom sin marknadskommunikation
The purpose of this study has been to create a communication plan to use at the launch of an independent fashion store and give a current storeowner an overall picture concerning which communication aspects to use during his ongoing business. To fulfill our purpose we have targeted one important question, which is: Which communication fields are the most important to use, when you are about to launch an independent fashion store. For this study we have used a qualitative approach in which we have conducted eleven personal interviews with people who has a strong understanding in communication regarding to this type of business. Most of our respondents are currently working actively with communication because they are active in retailing.The remaining respondent has a strong experience in the field of communication. In the final chapter we present our conclusions of the study. We have found the main factors in a communication plan, which is most important for a storeowner. Which are the most important communication parts for the owner to focus on before he launches the store? The basic need of knowledge in social mediaDevelop a unique concept to differentiate yourselfUnderstand the nature of networks and relationshipsThe relevance of store layout and sensory marketing which is an important tool when you need renewal and develop your concept.
Psykisk ohälsa bland barn och ungdomar i socialtjänstens öppenvård. : En kvantitativ studie om psykisk ohälsa, kön och socioekonomi i Södermalm och Rinkeby-Kista utförd med ?the Strengths and Difficulties Questionnaire?(SDQ)
The aim of this quantitative study is to describe the prevalence of mental health problems within the group of children and adolescents who receive support from two in home care units within the social services of Rinkeby-Kista and Södermalm stadsdelsförvaltning in Stockholm. Another purpose is to examine whether socioeconomic background and/or gender are associated with the prevalence of poor mental health, or mental health problems of a specific kind, in the studied population. Mental health is measured with the SDQ, a behavioral screening questionnaire that is widely used in Sweden and internationally. The study is based on data collected by the two units, which routinely screen children and adolescents with the SDQ. The main results of this study indicate that mental health problems are common in the studied population.
