En studie om läsintressets förutsättningar i skolan och hemmet
Samhället står i ständig förändring, och vi lever i ett informationssamhälle där vi ideligen kommer i kontakt med olika former av texter, vilket har fått till följd att det ställs andra krav på människans läsutveckling. Då forskning har visat på minskad läsförmåga hos elever i årskurs 4, ansåg vi det intressant att utveckla kunskap om hur elevers läsintresse kommer till uttryck i och utanför skolan, vilket också är studiens syfte. I denna studie har kvantitativ och kvalitativ metod kombinerats. För att få svar på vilka förutsättningar som har betydelse för elevers läsintresse utanför skolan, genomfördes en enkätundersökning. Elevernas enkätsvar användes som stöd när lärarna därefter intervjuades.
Blood compatibility of biomaterials made of recombinant spider silk
Native spider silk is an attractive lightweight natural polymeric material with a unique combination of strength, extendibility and flexibility. Synthetic, recombinant spider silk is an attractive biomaterial with several possible fields of application.
When a foreign material is introduced to blood, this can for example cause unwanted coagulation and complement activation.
The aim of this study was to investigate if coatings of heparin or albumin could improve the blood compatibility of films of recombinant spider silk and to develop an initial method to do so. Hypothetically, objects like pacemakers, stents and dental implants could be covered with spider silk films of high blood compatibility to reduce potentially harmful foreign body reactions caused by the immune defense. Increased blood compatibility would likely lead to improvements for both the individual patients and the society thanks to reduced load on healthcare institutions.
Our objective was to assess the blood compatibility of both functionalized and non-functionalized recombinant spider silk by evaluating coagulation and activation of the complement system of the immune defense.
Coagulation was evaluated visually on glass slides and complement activation was analyzed by measuring the concentration of the complement system mediator C3a in blood samples that had been exposed to the different materials.
This study introduces a non-toxic and easy performed method of improving the blood compatibility of recombinant spider silk films by adding a heparin coating.
Heparin coated surfaces had statistically significantly higher blood compatibility than uncoated surfaces. The effects of albumin coating of films were less clear compared to the results of heparin coated films.
Complement activation could not be evaluated because of high activation in all samples prior contact with the materials that were included in the study..
Hållbar stadsutglesning. Om människors inköpsresor och färdmedelsval före och efter etableringen av Allum köpcentra
External shopping malls in the context of urban sprawl have, according too much of the previous research, had a negative connotation when it comes to urban planning and a sustainable society. In recent years, some of this research on the issue has changed course towards that it might be some positive opportunities and elements in this development, given that it follows certain patterns. This latter development is what we have chosen to look deeper into in our study, Sustainable urban sprawl.The shopping mall Allum in Partille center has been the subject of this case study, to explore how people's shopping habits and travels in connection with these purchases has been affected by the establishment of an external shopping mall from a sustainability perspective.The method we used was a questionnaire distributed at workplaces in Partille. The collected data were then analyzed by using some of the dominant urban planning theories, for thus underpin our analysis. We have supplemented the study with a collection of information on existing and planned shopping centers in Gothenburg region.Our study shows that external shopping centers located in already developed areas, with an existing social structure, can help to create a more compact city with fewer and shorter shopping trips, and more sustainable transport choices when purchasing goods and services..

vuxnas läsning av skönlitteratur I became happier and wiser: young adults reading of fiction [123[upps-01.gif This Masters thesis explores young adults 18-26 years old, reading of fiction: their reading preferences, the meaning of reading and their access to literature. A study was made by way of a questionnaire, including 56 young adults, and seven qualitative interviews with two groups: one at a folk highschool and the other at a public library. The theories we have used to analyse the results are: theories of gender and youth, theories of literary genres, reader-response criticism, literature sociology and the theories of cultural sociology by the sociologist Pierre Bourdieu. In the analysis the results are compared to other studies of reading habits. Results from this study show that the young adults read fiction from several genres among popular- and quality literature.
Extramural English Activities. Teachers? perceptions of students? extramural English activities in relation to vocabulary
Because of the globalization of society, English as a foreign language (EFL) has become easier to access through internet and outside school English activities, so called ?extramural English activities? (EEA). Previous research indicates a positive relation between pupils? EFL vocabulary development and EEA (Sundqvist, 2009). This development may influence teachers? lesson planning, because of pupils? wide span of interests and the resulting different levels of EFL vocabulary.
Facebook och ansikte mot ansikte-kommunikation : En undersökning bland 100 ungdomar i Karlstads kommun om deras kommunikativa vanor
This essay deals with the subject of communication through Facebook. In this survey we studied 100 youths from Karlstad and their communication habits and behavior patterns on Facebook. The social network site Facebook has since its start in 2004 made a mark in modern communication. Today in 2010 the site has more than 500 million users. This paper wants to study what happens to other types of communication.
Genomgång av kemikalieförteckning som exempel på uppströmsarbete : en identifiering av utfasningsämnen i spillvattnet
Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.
Förhållandet mellan tandfärg och hur människors karaktärsdrag uppfattas. En studie utifrån tolkningar hos tandläkarstudenter från Sverige och Sri Lanka.
Inledning: Att skönhet och attraktivitet ger fördelar i livet har bekräftats i många studier. Tänderna är en bidragande faktor till hur människor bedömer varandra. Vita tänder föredras i många fall och missfärgade tänder är minst önskvärt. En studie visar att endast skillnader i tändernas utseende kan påverka hur vi uppfattar en annan människa och vackrare tänder kan få en person att uppfattas som mer intelligent och mer framgångsrik.
Syfte: Syftet med studien var att undersöka om det finns någon skillnad i bedömningen av personlighetsdrag utifrån ett blekt, ett missfärgat och ett omanipulerat bett, samt jämföra resultatet mellan hur tandläkarstudenter i Sverige och Sri Lanka bedömer detta.
Material och metod: Ett fotografi på en man och en kvinna manipulerades till tre olika utseenden: Blekt, omanipulerat och missfärgat. En enkät för att mäta karaktärsdrag utformades.
Att identifiera smärta hos personer med demenssjukdom : En litteraturstudie i omvårdnad
Background: Pain can be a constant problem in many older people's daily life, associated with particular physical and social disability, depression and poor quality of life. Dementia diseases are often associated with old age. Communication difficulties are one of the consequences of the disease, which clarifies the role of nursing staff in detecting and assessing pain. Objective: The aim was to compile knowledge about how nursing staff can identify pain in people with dementia. Method: A systematic literature review, where data were collected through manual and database searches.
Skillnader i självvärdering mellan kvinnliga och manliga tandläkarstudenter vid en ?Objective Structured Clinical Examination? (OSCE)
Syftet med denna studie var att jämföra tandläkarstudenters reella resultat på en Objective Structured Clinical Examination (OSCE) med deras egenskattade resultat. Dessa resultat jämfördes sedan med avseende på genus. Ett flertal studier finns publicerade där man har beskrivit skillnader i självvärdering mellan kvinnor och män på teoretiska examinationer. Dock saknas kunskap där man granskar dessa skillnader vid examination av kliniska moment. Vid teoretiska prov har man funnit att män har en tendens att värdera sina prestationer högre än vad kvinnor gör.
Avgörande faktorer vid affärsutbyten med Polen : en flerfallsstudie inom miljösektorn
Länsförsäkringar in Värmland, Sweden, had during the year 2003 a total level of 6.1 percent of people on the sick-list, which was higher than average in the business (4,5%) and for salaried employees in the private sector (3,3%). The average age of those put on sick-list was 47 years, whish is four years higher than the average for the whole LF-group. The cost for the total amount of people being on sick-list at LF-company (6,1%) was estimated to 1 500 kkr, according to a calculation model coming from Försäkringskassan. For every percent the sick level could be reduced, the company would save 239 kkr. To map out the state of health of each and every collaborator in LF, the company offered all employees to make a health profile at the company's health service, Clarahälsan AB.
Thinking more like a client. : Designfaktorer som påverkar valet av tjänsteföretag.
Companies in the western world can no longer compete by using traditional means such as product and price since the commerce of services continually grows. To avoid similarity and increase competitive advantages modern companies have to be more specified. The competition between companies has increased and customers are harder to reach. Customers of today can afford luxury but trend indicates that originality, identity, and status are more important than factual needs. Products created and consumed at the same time within the service market are often very homogenous (similar).
Genetisk variation av betydelse för adenosinsignalering vid nydebuterad reumatoid artrit
Rheumatoid arthritis is an autoimmune disease, where joints are attacked by the own immune system, leading to chronic inflammation and destruction of bone and cartilage. Inflammation is a complex process, controlled by many different substances. One of them is adenosine, which has anti-inflammatory properties. In this project, three polymorphisms in different genes, involved in synthesis and signaling of adenosine, were genotyped for 188 patients with RA and 362 controls without RA. The results shows that for the polymorphism in A2a, a gene coding for an adenosine receptor, there was no significant difference in genotype distribution between the groups.
Språkmedvetenhetens betydelse för inlärning av de naturvetenskapliga begreppen
Avsikten med detta examensarbete är att få en uppfattning om hur elevers läsvanor på fritiden påverkar deras betyg, naturvetenskapliga begreppsförståelse och språkbehandling. En grupp om 75 elever i år 8 fick skriftligt redogöra för sina läsvanor och förmodade höstterminsbetyg i svenska samt i de naturvetenskapliga ämnena. De ombads även förklara några vetenskapliga begrepp och sätta de naturvetenskapliga ämnenas svårighetsgrad i förhållande till övriga ämnen i skolan samt gradera sitt intresse för de olika naturvetenskapliga ämnena.Undersökningen visar en varierande kvalitet beträffande elevernas skriftspråk utan egentlig koppling till läsvanor. En majoritet har svårt att förklara de angivna begreppen ens ur vardaglig synvinkel. De elever som inte läser alls eller endast seriemagasin har dock till övervägande delen svaga prestationer i undersökningen och låga betyg, medan kopplingen är tydlig mellan goda läsvanor och höga betyg.
