Hälsa och datorkonsumtion bland pojkar i årskurs nio : En komparativ tvärsnittsstudie

The aim of this study is to investigate the prevalence of computer consumption among boys in ninth grade, and to see if there were any differences with regards to physical activity, sleeping habits, breakfast habits and BMI. The study has cross sectional design with a comparative and a quantitative structure and is based on a former study called ?Food & Health 2007?.  The respondents were represented by 181 boys in ninth grade, recruited from ten different schools in the county of Uppsala, who were answering questions about media consumption, breakfast habits, physical activity and sleeping habits. Daily computer consumption was reported up to one hour for 12 % of the respondents, one to three hours for 65 % and over three hours for 42 %. The boys who had a high physical activity level were less frequent in computer consumption while those who had a low physical activity level spent more time by the computer.

Utveckling av golvlucka för hoppgropssystem i kommunal idrottshall

In this thesis a concept for floor hatches for foam pits has been developed. Since there is an existing solution that is powered by hydraulics and is expensive, the goal was to develop a cheaper solution, as simple as possible.A number of different concepts were developed and evaluated. A concept with five sections that are pulled to the side and stacked on each other was chosen as it was thought to have the lowest risk of crush injuries and to be easiest to manage and control. In the opening behind the foam mattress a lifting table is placed to regulate the height of the stacked sections.To be allowed to be installed in the floor of sports halls the sections must be dimensioned according to the construction standards for these types of buildings. Different dimensions of beams in steel and wood materials were evaluated and of those, who lived up to the requirements of the standard, a concept was chosen.

Läslust och läsförståelse bland elever i grundskolan : En undersökning utifrån lärarens och skolbibliotekspersonalens synsätt

The poor results of 15 year old Swedish students in the 2012 PISA-investigation serve as the main inspiration for this essay. Though aware that PISA measures a range of skills, including math-, science- and reading abilities, a deliberate focus has been placed on the latter. Unsatisfactory math- and science results are sure to bare consequences ahead, but poor reading skills affect the comprehension of all other subjects combined and is therefore of utmost importance.This essay explores the roles of teachers and school librarians in the promotion of reading, as well as their ways of cooperating in strengthening students' reading abilities. Questions of particular interest are:? In what ways do teachers' and school librarians' views of ongoing reading promoting activities differ?? How does the school and school library contribute to reading promotion and reading comprehension among students?? What factors unite teachers and school librarians in their attempts to promote reading, as far as pedagogical roles are concerned?Working on this essay, a total of seven qualitative interviews were conducted.

Sexualvanor och preventivmedelsanvändning hos svenska gymnasieelever

The aim of this study was to examine sexual behavior, contraceptive use, self-rated health, lifestyle factors and the prevalence of HPV vaccination among last year high school students. The study was a quantitative cross-sectional study which was a substudy of the longitudinal study " Pornography, Youth and Health". Results showed that the majority of students had had sexual intercourse (75 %, n=524) and both performed (67 %, n=479) and received oralsex (70 %, n=498). Forty percent (n=282) of the students had had one night stand, a quarter (n=159) anal sex and 29 (n=202) percent sex with a friend. The contraceptive use increased from the first to the last intercourse while the use of condoms decreased.

Arkitekturer i operativsystem: en fallstudie i monolitisk och micro kernel

Den tekniska utvecklingen driver fram allt mer avancerade datorsystem. Samtidigt ställs allt större krav på stabilitet och flexibilitet i de operativsystem som ska användas på dessa system. De senaste årtiondena har micro kernel arkitekturen varit föremål för intensiv forskning och det finns idag ett flertal operativsystem på marknaden som använder denna arkitektur. Traditionella monolitiska operativsystem är relativt resurskrävande system som ofta anklagats för att sakna struktur. Micro kernel baserade system är en lösning på detta problem där man bantat ner kernel till så lite som ett tiotal kilobyte och flyttar ut tjänster som normalt ligger i kernel till user space. Solaris och Linux bygger på en utveckling av monolitisk kernel där man byggt operativsystemet i ett antal sinsemellan beroende lager vilket bidrar till ökad struktur i systemet. Flexibilitet uppnås i dessa system genom att man lägger till funktionalitet för att under exekvering länka in ny kod i kernel. Windows NT och Mac OS X är baserade på micro kernel arkitektur.

Länkar till verklighet: En arkeologisk studie av ämnesstrukturen i Open Directory Project

The thesis examines the view of reality as expressed in the subject structure of the web directory Open Directory Project. This is analyzed in comparison with library classification systems, regarded as products of the modern library movement. The question is raised whether the world view of the directory, in contrast to the modern classification systems, can be seen as an expression of postmodernity. Postmodernity is then understood as a radical critique of the modern belief in neutral science and technology as ways of objectively describing the universe of knowledge. The theoretical and methodological approach adopted is borrowed from a poststructuralist reading of Michel Foucault's archaeology and sociologically coloured classification research.

En organisationscentrerad metod för att automatisera en affärsprocess : Med hjälp av interoperabilitet, modellering och designmönster

Med hjälp av design science och delar ur en traditionell systemutvecklingsmetodik så har vi tagit fram ett designförslag åt en organisation med vad som kan anses som traditionella problem med interoperabilitet. Vi har därefter härlett en organisationscentrerad metod för att automatisera en affärsprocess ur den erfarenhet vi fått genom att ta fram designförslaget..

Arbetsmotivation och psykisk hälsa bland sjuksköterskor inom psykiatrin : En jämförande studie mellan yngre och äldre sjukksöterskor

Background: The relation between work motivation and well-being are relatively well theoretically entrenched, but few studies have been conducted on nurses within psychiatry. Objective: The aim of the present study was to examine the differences in intrinsic work motivation (autonomy, competence, relatedness), mental health and burnout between young (?40 years) and older (>40 years) nurses employed in psychiatry. Method: The study was an observational study with a cross-sectional design and group comparisons, conducted as a survey. The sample constituted of 60 employed nurses.

Kunskapens tempel eller kunskapens saluhall: En diskursorienterad studie över förarbetet till Stockhoms nya stadsbibliotek

The aim of this master´s thesis is to explore how Stockholms new library´s identity is constructed, and further to relate the case study to a general discussion of the identity of public libraries in Sweden. This is done through analysis of the visions and plans that the planned library is based on. We feel that it is a relevant study since questions concerning the public library's identity are for library and information science as well as the institution. Questions posed in the study are: How is the roles and identity of the planned library described in the texts that form the basis of the project? What characterises the relationship between the present and the planned library? What discourses concerning the public library's identity can we see in the material?The theoretical framework of the thesis is a discourse oriented analysis based on the critical discourse analysis of Norman Fairclough.

Web Services - Aspekter på nya affärsmöjligheter

E-business innebär att företag använder Internetteknologier eller nätverksteknologier för att skapa större affärsnytta i deras affärsprocesser. För att kunna genomföra automatiserade affärsprocesser krävs att de olika system som används är interoperabla, d v s kan kommunicera och fungera ihop på ett effektivt sätt. Målet med Web Services är att skapa hög interoperabilitet, vilket gör denna teknik lämplig för e-business. Företag kan specialicera sig på att skapa specifika Web Services. Dessa Web Services kan sedan vara byggstenar åt andra företags tjänster. Det krävs då att Web Services kan integreras på ett bra sätt så att de verkligen bildar en affärsprocess. Därför är även frågor kring hur integration mellan Web Services ska gå till, viktigt ur ett e-bussiness perspektiv. Det vi kommit fram till är att det går att minimera integrationsproblemen genom att anvä nda de mest standardiserade protokollen och följa vissa riktlinjer vid skapandet av Web Services.

Påföljder, Microsoft mot Kommissionen

Microsoftdomen grundar sig i att Microsoft vägrat lämna ut interoperabilitetsinformation till en av sina konkurrenter (Sun). Sun menar att detta konstituerar ett missbruk av dominerande ställning och lämnar in ett klagomål till Kommissionen som påbörjar en utredning. Kommissionen börjar dessutom på egen hand utreda huruvida Microsofts integration av Windows Media Player i sitt operativsystem (Windows) kan utgöra ett missbruk. Den 17 september 2007 blev Microsoft dömda av Förstainstansrätten för missbruk av dominerande ställning. Detta ledde till ett par påföljder för Microsofts del.

En effektivare källsortering för bättre materialutnyttjande - en behovsanalys

The waste fractions offered to households in Sweden differ depending on where you live. The responsibility for the waste are grounded by the Swedish law where the municipality are responsible for the collection of household waste and FTI are responsible for collecting all packages and papers that the households sorts out. A new waste regulation is under consideration where the responsibility for the household waste may change. The bulky waste from households is collected at recycling centers where the households leave it in different containers for different fractions. These recycling centers are formed different and the fractions offered in them also differ depending on in what municipality they are located.
