Riskbeteende och sociala nätverk : Spridningen av blodburna infektionssjukdomar

Blood-borne infectious diseases such as Human Immunodeficiency Virus (HIV)and Hepatitis C Virus (HCV) spread when the addicts share needles and injecting equipmentwithin contact networks. A quantitative cross-sectional study was conducted in Winnipeg,Canada in December 2003 - September 2004. Through a special questionnaire, respondentswere asked to answer questions about themselves and about their contacts, about relationshipsand how they shared syringes and other injection supplies. Blood tests were used to identifywhether they carried any blood-borne infectious diseases. We selected some variables from theoriginal data set.

Enterobacteriaceae och amoxicillin-klavulansyra : Effekt av bestämt förhållande respektive bestämd koncentration av klavulansyra på MIC-värden och zon/MIC-korrelation

Förekomsten av bakterier med olika typer av resistensmekanismer ökar globalt. De varianter som på engelska benämns ?Extended spectrum ?-lactamases? (ESBL) är en heterogen grupp ?- laktamaser som genom hydrolys inaktiverar ?-laktamantibiotika och därigenom ger resistens mot bland annat ? -laktamantibiotika som penicilliner och cefalosporiner. Resistensbestämning på kliniska laboratorier utförs huvudsakligen med lappdiffusion eller Minimum Inhibiting Concentration (MIC)-bestämning med gradienttester. Infektioner orsakade av ESBL-producerande organismer kan behandlas med ?-laktamantibiotika kombinerat med en ?-laktamasinhibitor.

Hållbarhetsredovisning : Med fokus på negativ information

To establish sustainability reports is an increasing trend for more and more companies. This has led to a spread of the international framework Global reporting initiative, GRI, guidelines to make a sustainability reports. This trend has got a lot of critics from various stakeholders who believe that companies in these reports communicate the information in a way of window dressing. Both negative and positive information has to be represented according to GRI: s principle of balance.  Window dressing is created by adding a greater emphasis on the positive information. The researchers review the context of the negative information to study the extent to which it is reported and whether there are patterns and variations in the reported information.

Hur arbetar lärare med laborativ matematik? : En kvalitativ studie om hur fyra lärare arbetar främstmed avseende på laborativa inslag i undervisningen igrundskolan

The objective of this research is to unveil how respective teacher consider about the laboratory working methods in mathematics. The research even includes answers to questions such as, what approaches and attitudes the teachers have and the methods they use when instructing their students when teaching mathematics, what the materials used by the teachers are and how important working creatively is to help the students develop their logical thinking. I also looked into issues that can help understand how and why teachers use laboratory mathematics for students in young ages. As a conclusion the research showed that the teachers aim to the goal that includes helping the students understand mathematics, strengthen their logical thinking and creativity.In the method section qualitative data was used, which contained four interviews with different pedagogues that daily interact with students in elementary school. The reasons for using the method of qualitative data was to help me deeper understand and answer the specific questions I had to the pedagogues and to even compare how different pedagogues differ in their approaches and methods.

Poked av politiker : En studie om MUF och SSU:s politiska kommunikation på Facebook

The new media landscape is growing by the minute with blogs, web pages and different communities. The latest phenomenon that has grown rapidly throughout the world is Facebook. This is at new platform for communications where individuals can meet and socialise. Even political actors have started to appear on this community to work and spread their opinions.

Learning Resource Centre (LRC) ? en bibliotekstrend?

Learning Resource Centre, or LRC, is an international phenomenon and a response to the changing society that came with the development of information technology. The LRC concept spread internationally during the 1990s and began to influence Swedish collage libraries at the end of the decade. The main purpose of this study is to analyze if and how Swedish college libraries have incorporated the LRC concept. Is there a Swedish LRC model? Is the LRC concept still interesting or was it a trend that is now out of date? Interviews with eleven people from six college libraries aim to show how they define the concept LRC and how it has been integrated in to their organisations.

Pappersfoton i den digitala eran: Hur företag kan agera vid ett tekniskt skifte

The spread of digital photography has created major changes in the previously stable Swedish photofinishing market. We investigate how companies act to survive in the face of technological change, through our research question: What strategies have actors in the photofinishing business chosen during the changeover from analog to digital photofinishing? Using a deductive method, we have conducted semi-structured interviews with 11 actors in the photofinishing business. Innovation management studies innovation from a number of perspectives, describing effects of innovations on the competitive ability of established actors, and on the value of their resources. The companies were not prepared for the speed of the change.

Främlingsbilder : Om judar och judendom i medeltida danskt och svenskt kalkmåleri

This thesis deals with the Jewish motifs of the medieval mural paintings in Denmark and Sweden; the presences of the motifs are of interest considering that no Jews were allowed entry into Scandinavia at the time. The purpose of the thesis is to study the Europeaninfluences in the medieval depiction of Jews and Judaism in the Danish and Swedish churches and the purpose for the production of the paintings. To this end, the Danish and Swedish mural paintings ? as well as the medieval texts and motifs of Jews and Judaismthat were used as source material ? are studied with respect to the attitudes conveyed. The Danish and Swedish mural paintings are unevenly distributed both within the groups of motifs as wells as its chronological and geographical spread.

Privata skogsägares attityder och anpassningar till klimatförändringar : En fallstudie i Kronobergs län

Conditions for Swedish forestry are expected to change in the future due to the climate. Among other things, increased production is expected in a warmer climate, mainly because of a longer growing season. With the changing climate risk of damage by such as insects, fungi and storms are expected to increase. Hence, it is of highest importance for private forest owners to spread these risks in the way they cultivate their forest. In this study a qualitative method was used to examine ten private forest owners with forest properties within Kronoberg county, Sweden in their attitudes and actions to prepare in terms of climate change and if they have been affected by the climate change debate in their forest decisions.

Livsmedelsproducerande djur : en källa för antibiotikaresistens?

Antibiotikaresistens är idag ett viktigt globalt folkhälsoproblem. Ifall vi förlorar antibiotika som skydd mot bakteriella infektioner kommer det att påverka både samhälle och individ i form av ökade samhällskostnader och för individen en ökad morbiditet och mortalitet. Den viktigaste orsaken till uppkomst och spridning av resistens är användning, däribland felaktig användning, av antibiotika vilket selekterar för resistensutveckling. En annan faktor som bidrar till en ökad resistensutveckling är att samma typer av antibiotika används inom flera sektorer: inom human- och veterinärmedicin såväl som inom djuruppfödning och jordbruk. Resistens inom en sektor kan spridas vidare till en annan, till exempel kan resistenta bakterier spridas från djur till människa genom direkt eller indirekt kontakt.

Babesios : en fallbeskrivning samt diskussion av fästingburna sjukdomar hos nöt i Sverige

Many farms in the counties in the south of Sweden have difficulties with diseases spread by ticks; mainly babesiosis and tick-borne fever (TBF) but there are indications that borreliosis ought to be included. All of the tick-borne diseases radically decrease farm profit if the herd is affected. The production of the vaccine used against babesiosis since the 1920´s, will be discontinued in the near future and in addition to economical reasons it is therefore important to learn more about the diseases above. During the summer and fall of 2002 and 2003, a farm in the island of Gotland was burdened with unusually many cases of bovine babesiosis. In total 43 animals fell ill and one died.

Biblioteken som glöder. En studie av ideellt drivna bibliotek i Uppsala kommun och eldsjälarna bakom dem

The purpose of this bachelor thesis is to study, describe andimprove the understanding of voluntary driven libraries. How doesthe library staff view their role? How is the library operationworking in respect of economy, organization structure and systemsof rules? Research methods I used were semistructured interviewsand document research.The theoretical framework was based on Joacim Hansson´sdiscussion about libraries in a local community, Henning Bang´sdiscussion about organization culture and the Swedishgovernment´s non- profit advisory group`s discussion aboutvoluntary work.The results of this study shows that the library staff are enthusiastsmotivated by a wish to spread literature to people who find itdifficult to visit municipal libraries. Other motives for theirvoluntary work is the opportunity for being a part of a socialcommunity, to be surrounded by books and to activate body andsenses. The results of this study also shows that the voluntarylibrary system differ from the traditional, municipal library systemconcerning economy, organization structure and set of rules..
