Kan fysisk aktivitet förebygga Alzheimers sjukdom? En litteraturbaserad studie.

Introduction: We are facing an aging population, which means that the incidence of age related diseases, such as Alzheimer's disease, are expected to increase. In the current situation there is no cure for the disease, whereupon it is important to develop preventive strategies. Objective: To examine the association between Alzheimer's disease and physical activity. Method: A systematic literature search was done to identify the current state of knowledge from the year 2006 onwards. The reason for this limitation was that the SBU commissioned a systematic literature review in 2006, where the relationship between physical activity and Alzheimer's disease could not be determined.

Är en annan värld möjlig? - En studie från urban- till world-bias

The purpose of this thesis is to explain one aspect of how and why the development in the third world is lagging behind. The precondition is that development through an agricultural revolution is necessary and that all countries benefit from trading. But these two conditions are not met today. By using the urban-bias and the world system theory I have analysed how the situation appears to be according to the precondition. It appears that both the urban-bias and the world system theory are essential to understand how and why the situation in third world still has not reached the same development phase as most other countries.

Leder kritisk publicitet till kritisk publicitet?

Academic research indicates that critical publicity can have a detrimental effect on brand attitudes. The negative effects have been showed to be buffered by Cognitive bias elicited by strong favourable attitudes, commitment, brand certainty and brand identification. It has been proposed that the influence of such bias in a news reporting context should be studied, something that also is interesting from a brand perspective. The study therefore investigated whether a well-publicised scandal in one period can lead to increased critical publicity in the coming periods. A case study of Swedish grocery chain ICA was conducted.

Actor observer bias : Påverkar könet hur vi attribuerar?

Actor-observer bias är benägenheten för människor att attribuera sitt eget beteende utifrån omständigheter och andras beteende utifrån deras person. Vi tenderar dessutom att favorisera och vara mer förlåtande i attributionerna till de som tillhör vår ingrupp. Studiens syfte var att undersöka huruvida graden av tillhörighet till ingruppen, kön, påverkar hur vi attribuerar. Studien genomfördes med 102 deltagare, 51 kvinnor och 51 män. En konfliktsituation mellan ett par presenterades för deltagarna där den ena parten i förhållandet (X) beter sig illa mot den andra.

Bias vid skattningar av tidsvinst, bromsförmåga och olycksrisk itrafiken: Är de ett bestående problem och finns det ett sambandmed bedömarens upplevelse av sin numeriska förmåga?

Svenson (2009) har visat att olycksrisker, restidsvinster ochinbromsningshastigheter i trafiken skattas med systematiska fel.Svensons studier har replikerats i denna studie för att se om de biassom tidigare upptäckts består. Studien undersöker också om det finnsen korrelation mellan storleken på bias och resultatet på subjectivenumeracy scale (SNS). Fagerlin et al. (2007) utvecklade SNS som ettverktyg för att mäta den subjektiva upplevelsen av en personsnumeracy. I denna undersökning har SNS översatts till svenska frånengelska och skalegenskaperna för den svenska versionen har ocksåundersökts.

Actor-observer effekten och bilkörning : Hur attribuerar människor beteenden vid riskabel bilkörning?

Actor-observer bias är tendensen där människan som aktörer tillskriver sitt beteende till yttre omständigheter medan observatörer tenderar till att tillskriva aktörens beteende till personliga faktorer. Syftet med denna studie var att få en klarare bild av hur människor i sin roll som aktör eller observatör attribuerar ett riskabelt bilkörningsbeteende. Deltagarna bestod av 101 svenska studenter från en högskola i Mellansverige varav 77 stycken var kvinnor och 24 stycken var män. Deltagarna fick svara på en enkät angående actor-observer bias och riskfullt bilkörningsbeteende. Resultaten visade att andras beteende förklaras mer av personliga egenskaper än då personen själv kör riskfullt medan yttre omständigheter inte gav skillnad för vare sig andra eller en själv.
