När bina tystnar : Colony Collapse Disorder bakom honungsbiets (Apis mellifera) försvinnande

Under vintrarna 2006/2007 och 2007/2008 vittnade man i USA om storskaliga förluster avhonungsbin (Apis mellifera). Gemensamma symptom för dessa förluster var att arbetarbinförsvann från kolonierna fastän det fanns rikligt med mat och inga tecken på infektion av någonparasit. Fenomenet fick namnet Colony Collapse Disorder (CCD) eftersom det slutgiltigastadiet var att kolonierna kollapsade. Denna översiktstudie ämnar till att reda ut begreppetCCD och se över vilka potentiella orsaker den rådande forskningen föreslår och vad man harkommit fram till sedan utbrottet 2006. Resultaten indikerar att det antagligen inte är en ensamfaktor bakom CCD utan att flera faktorer samverkar.

Tambins inverkan på naturligt förekommande pollinatörer

Det här arbetet handlar om tambins inverkan på naturligt förekommande pollinatörer. Min frågeställning berör: tillgången på näring, hälsotillståndet och populationsnivån hos naturligt förekommande pollinatörer i förhållande till tambins närvaro. Det som framkommit av den här litteraturstudien är att introducerade tambin leder till att naturligt förekommande pollinatörer minskar i antal kring bikuporna, en del arter söker föda på andra blommor eller senare på dygnet än tidigare. Den minskade tillgången på föda som denna konkurrens innebär har en negativ inverkan på humlors kroppsstorlek och därmed deras överlevnad. Samt att tambin kan föra över patogener så som varroakvalster, nosemasjuka och deformed wing virus till humlor vilket leder till minskad livslängd och sämre fortplantning..

Kollektiv kollaps i ett handbollslag på elitnivå: en studie med fokus på emotionell smitta

Collective collapse occurs when a majority of players in a team suddenly perform below expected level in a match of great, often decisive, importance in spite of a normal or good start of the match or when a team underperforms right from the start of the match. The aim of this study is to investigate collective collapse, focusing on emotional contagion. The study is a qualitative study based on semistructured interviews with nine handball players in an elite team. The results show six factors presented as themes. These are Preparations, The coach and leadership, Emotional contagion, Communication, Role Acceptance and Incongurence.

Bi och vi : En möbel att vila sin tyngd på som belyser det stora i det lilla.

Relationen mellan bi och människa är så pass gammal att man inte helt säkert kan säga när den uppkom, men man vet säkert att honungsbin varit tämjda av människan i minst 4000 år. Under hösten 2006 och våren 2007 skedde dramatiska förluster av honungsbin i USA och Kanada. Colony Collapse Disorder, (CCD) kallades syndromet och snart kom det även oroande rapporter från europeiska länder om ovanligt stora vinterförluster. Kontentan är att förlusten av biologisk mångfald är något som borde oroa hela samhället och när pollinerande insekter försvinner är det särskilt oroväckande, då detta i sin tur kan ha en negativ inverkan på växters reproduktion.Detta projekt utgår från frågeställningen: Hur kan jag som designer inbjuda till en kroppslig upplevelse av problematiken kring bidöden? Projektets ledord är skörhet och ?det stora i det lilla? och artefaktens primära funktion är att synliggöra och undervisa i känslan av vad bidöden kan medföra, snarare än att vara kommersiellt gångbar eller förhålla sig till en tydlig målgrupp.

The distinction has been made by dividing them up into a contemporary cluster, that were published before the 1900?s, as opposed to the more recent literature, from after the 1900?s.

Patologiskt samlande -en funktionsnedsättning : En kvalitativ intervjuundersökning om professionella aktörers erfarenheter av arbete och hjälp i förhållande till patologiska samlare.

This qualitative interview study examines the shared and discrepant experiences that nine professionals, three from each field of psychiatry, social service, and housing have from working with people with hoarding disorder, and their view on help. The main difficulty when working with hoarding disorder is described as lack of insight and understanding of the severity and consequences of the disorder among people with the disability. Professionals highlight the importance of proper diagnosis and cooperation among disciplinary teams working with hoarding disorder. Approaches differ regarding the issue of how to best help a person with hoarding disorder, especially as the emphasis of autonomy becomes more prevalent. The landlords who were interviewed expressed the hoarders? need of help from the society, whereas the social service interviewees accentuated voluntariness and motivation as a favorable long-term management.
