En bibliometrisk underso?kning av bibliometrins utveckling : Underso?kning av hur publikationen av bibliometriska, informetriska, scientometriska och webometriska artiklar har utvecklats sedan 1960- talet
The main purpose of this bachelor thesis is to analyse the publication- and citation patterns of the articles concerning bibliometrics, informetrics, scientometrics, and webometrics which can be found on Web of Science, and give a brief description of how the definition of the four terms has developed. I have looked at how the number of published papers have developed over the years and to what extent they have been quoted by other researchers. I have also briefly adressed what other research fields are referring to articles published in the four areas. The material I looked at includes articles that can be found on Web of Science with one (or more) of the four terms as topic and are categorised under library- and information science starting with the first bibliometrics article which was published in 1969, and ending in 2013. The results show that the publications in all four fields are continuously increasing.
Gröna lösningar - en fallstudie av aktuell teknik för energieffektivitet för Skanska Sverige ab
ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level.This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis.
Renovering av Gamla Årstabron med injekteringsbetong
Gamla Årstabron i Stockholm uppvisade efter 80 år i drift omfattande skador på de bärande betongkonstruktionerna enligt en utredning som genomfördes 2006 av dåvarande Carl Bro AB på uppdrag av dåvarande Banverket Region Öst. Det konstaterades att omfattande reparationer och förstärkningar av brons betongvalv var nödvändiga för framtida rationell drift av bron. Det beslutades efter vidare utredning att de första tre valven på Södermalm i Stockholm skulle renoveras med injekteringsbetong. Renoveringen av de tre valven på fastlandet på Södermalm var ett prov i full skala för att hitta den optimala metodiken för den fortsatta renoveringen av resterande 17 betongvalv. Det här examensarbetet syftar till att utvärdera metoden med injekteringsbetong med hänsyn till injekteringsbetongens egenskaper, material och produktionsteknik. Bakgrunden till detta examensarbete är att det finns ett stort behov av att följa upp renoveringsmetoden med injekteringsbetong eftersom den inte har använts i någon större utsträckning i Sverige sedan slutet av 1970-talet.
Informationskompetens i Tyskland och Sverige : En jämförande studie av användarundervisningen vid två högskolebibliotek
This master?s thesis studies library teaching at two university libraries, Freie Universität Berlin in Germany and Södertörn University in Sweden. The aim of this paper is to study views on information literacy, how these views affect teaching practice, and how the teaching of information literacy is connected to, on the one hand, German and Swedish learning culture and, on the other, the local community of practice at the studied university libraries. The theories applied in this paper are learning culture and community of practice as developed in the works of Judith Ricken and Etienne Wenger. The methods that have been used are qualitative, semi-structured interviews that were conducted at both university libraries.It was observed that the teaching practices were highly connected to learning cultures.
Slöjdens mening och nytta : För eleven i grundskolans senare år
Syftet med studien var att förstå betydelsen och nyttan av slöjdämnet i grundskolanbetraktat genom elevers berättelser om ämnet.De frågeställningar som jag utgick ifrån var:· Vilken karaktär av kunskaper uttrycker eleverna att slöjdämnet leder till?· Vilken mening och nytta uppfattar eleverna att slöjdämnet har?Litteraturavsnittet tar upp slöjdämnets historia, tillkomst och förändring fram till dagenskursplan och läroplan. Vidare tas kunskapsbegreppet upp utifrån läroplanen, Aristotelesfilosofi samt Vygotskijs sociokulturella teori.Den andra delen av litteraturkapitlet behandlar slöjdämnets kompetenser såsompedagogisk process, kropp och kommunikation samt entreprenöriellt lärande.Elevers dagboksanteckningar samt deltagande observationer utgjorde data. Deslöjdkompetenser som eleverna gav uttryck för och som jag såg i mina observationervar entreprenöriell kompetens, kroppslig och kommunikativ kompetens,processkompetens samt en känsla av lust.Resultatet visade att den betydelse och nytta eleverna tillskriver slöjdämnet är desskaraktär av konkretion samt av engagemang och delaktighet.I diskussionen kopplas litteratur och resultat ihop med egna reflektioner. En av defrågor som studien bidrog till är hur och om de praktiska och estetiska ämnena kan sessom utgångspunkt för mer teoretiska ämnen? Mot bakgrund av studiens resultat kan detfinnas outnyttjade möjligheter att dra nytta av slöjdämnets fördelar inom andra ämnen..
Upptryck : En jämförelse mellan RIDAS och internationella riktlinjer
Old hollow trees of oak contain a large amount of wood mould. Unfortunately, these trees have in the last century been greatly reduced in numbers. It has resulted in that species that depend on these habitats, saproxylic species, have become at risk to decrease in numbers or die out regionally. Previous studies have shown that the volume of wood mould is an important factor for occurrence and population size of saproxylic organisms. The aim of the present study was to examine how the volume of wood mould varies among ash (Fraxinus excelsior), lime (Tilia sp.), maple (Acer platanoides), aspen (Populus tremula) and oak (Quercus robur).
Mötet mellan psykiskt funktionshindrad individ och sällskapsdjur : En etnografisk studie om interaktionens betydelse för känsla av välbefinnande.
The purpose of the study was to find out whether the interaction between mentally disabled individuals and pet positively affects the individual and gives a feeling of well-being to the extent that this might be implicated in the psychologically disabled people?s everyday life in some form of rehabilitation measure. The study is qualitative and builds on an ethnographic design. Data collection was performed through six observations, six interviews and reflections. Interviews were also conducted with relatives and assistants for greater opportunity for follow-up questions, and descriptions of the situation.
Konstruktion av serviceutrustning till tunnelborrningsmaskin
The Master Thesis work this report is based upon has been conducted in cooperation with Svea Teknik AB. Svea Teknik is a consultant firm which is developing parts of a tunnel boring machine on behalf of Atlas Copco. The machine is being developed to mechanically excavate hard rock by fixating itself in the tunnel and then press a large rotating cutter-wheel equipped with disc-cutters against the tunnel wall. The disc-cutters are the tools that are in direct contact with the hard rock and are therefore exposed to extensive wear and needs to be replaced on a regular basis.The purpose of this Master Thesis has been to develop a service equipment that will enable time effective and safe changes of disc-cutters. The disc-cutters have a diameter of 17 inches and weigh about 130 kg.
Ideologiska skillnader mellan socialdemokraterna och moderaterna : En idéanalys av olika politiska sakfrågor
ABSTRACTEssay in political science, C-level by Cecilia HolmbergSpring semester 2006, Tutor: Arne Larsson- Ideological similarities between the Swedish Socialdemocratic and the Swedish conservative party- An idealanalysis of different political issuesThe purpose of this essay is to examine wheater the political ideologies have lost their importance in the Swedish political system. The study will focus on the ideological similarities or differences between the two largest parties in Sweden, the socialdemocratic and the conservative party. Therefore, the main research question is:? Are there any ideological similarities or differences between the socialdemocratic and the conservative party?To be able to answer this question, I have used Herbert Tingsten?s idealanalysis. This type of analysis examines how someone, in this case a political party, describes reality.
Cellarmering : En jämförande studie mellan traditionell betongarmering och en ny typ av armering innefattande projektering och produktion
Idag, inte bara i Sverige, bygger man mer och mer i betong. Betongkonstruktioner ses inte längre som något kallt, grått och tråkigt då man kan uppföra byggnadsverk som inte bara är starka och tåliga utan även med originella former och färger. För att få betongen stark, inte bara i tryck måste så gott som alla konstruktioner dock armeras på ett eller annat sätt. Dessa nya och ofta komplicerade former på konstruktionen ställer nya krav på armeringsmetoden som används, trots detta har sättet att armera i stort sätt sett likadant ut i många, många år.I den här rapporten kommer man att utreda möjligheterna för en ny typ av armering att etablera sig på en mycket konservativ marknad där utrymmet för utveckling och nytänkande är till synes mycket litet.Jämförelser mellan traditionell armering och denna nya cellarmering har gjorts, framförallt med avseende på projekterings- och utförandenivå. Detta har gjorts genom intervjuer med sakkunniga, både ute på byggarbetsplatsen och i armeringsverkstad.

Result: The core category ?From uncertainty to relief with newly acquired experience? could summarize the result of this interview study.
Barnarbete : En lokal studie av barnarbete i Stråssa gruva under början av 1900-talet
AbstractBachelor essay in Pedagogy by Johan Lidén &Kristian Sagfors, 2011."Genus i gymnasieskolan: En oengagerande fråga?".Supervisor: Zeki YalcinGender and gender equality in our school system has throughout the years become a well researched subject, however most of that research has focused on the lower levels of compulsory school. The upper secondary school has not gotten the same attention.We have chosen to explore how social science teachers in upper secondary school treat the subject of gender and gender equality, what strategies they apply in the classroom and how their pupils respond to the subject.We wanted to get access to their classrooms so we could do an ethnographical study to find the answers to how their lessons were planned and executed, if different teachers made different didactic choices depending on the orientation of the class. As our work progressed we ran in to an interesting problem which ultimately made us rethink the purpose of this paper.In our pursuit of respondents we contacted many schools by e-mail and later visited the schools to find participants. This proved difficult as we were met with a wall of silence and lack of interest.
?I ain?t goin? in there!? : HIV-infekterade patienters upplevelse av vården

Byggnads- och investeringskostnader : Robotmjölkning eller konventionell mjölkning?
This project is based on my fathers farm which lays outside Löberöd, twenty kilometres south
of Eslöv in Skåne.
While my family for some time have thought about building a new milkingstable with
AMS(Automatic milking system) I decided to compare the AMS with a conventional
milkingstable. We are abit concerned about how many cows we should have in the new
stable. Because of that I calculated with two different number of cows.
I have compared three different types of milking stables:
One alternative is 180 cows milked in a double eigth hearing bone milking stable.
The second alternative is 128 cows milked with two DeLaval VMS-robots.
The third alternative is 171 cows milked with three DeLaval VMS-robots.
One salesman from DeLaval and one salesman from A-betong helped me to get marketprices
on the milkingrobots, building, ventilation and prices on all the concrete. In all the costs
labour is included.
The rest of the costs are calculated in a softwareprogram called K-data 03 which is a program
with predicted costs. The calulations from the program showed that the price in the milkingpit
system was 51 000 sek per cow.
