Intermediate domain? : En intervjustudie med förskollärare
Den här uppsatsen handlar om hur förskollärare idag upplever samarbetet mellan förskola och hem, deras beskrivning av förutsättningar för ett gott samarbete och vilken betydelse den nya reviderade läroplanen (Lpfö98/10) har för samarbetet.Syftet med uppsatsen är att undersöka hur förskollärare upplever samarbetet hem- förskola. Den empiriska delen grundas på sex intervjuer med förskollärare som har avlagt sin examen under fyra olika decennier. Intervjuerna har genomförts med fokus på att lyfta fram deras syn på de barndomssociologiska begreppen being och becoming (med svensk översättning varandesyn och projektsyn) och frågor kring just samarbetet förskola - hem.De fyra teman som uppstod ur analys av intervjuresultatet var: 1. Växelverkan mellan being och becoming, 2. Samarbete påverkat av den dagliga dialogen och förskollärares uppdrag, 3.
Differences in host plant preferences and olfactory physiology between populations of the moth Spodoptera littoralis established in Egypt and Benin
This study was made to compare and distinguish any differences in olfactory recognition and
host plant adaptation between two strains of cotton leaf worm, Spodoptera littoralis. The
populations used were established in Egypt and Benin, Africa. The documentation consisted of
information about (1) each of the strains development through the larval stage up to pupation on
diets of cotton, clover and cowpea. (2) Their oviposition preferences as adults between cotton,
clover, cowpea, maize and cabbage. (3) Electroantennographic recordings to quantify any
possible responses to plant volatiles.
Throughout the diet experiments the larvae from the Benin strain showed significantly a better
development between artificial, clover, cowpea and cotton respectively, while the Egypt strain
had significance between artificial, cotton and cowpea/clover as diet.
Also noted was how the strains substantial development of weight differentiated if fed the cotton
diet, followed by the cowpea diet showing that the Benin strain would develop a higher body
mass on a cotton diet as well as on a cowpea diet.
This trend was however switched once the pupal stage was reached, where the Egyptian strain
contained a significantly greater body mass than the Benin strain on the artificial and the Benin
strain a greater on cowpea, which suggests that in the end, the Benin strain develops significantly
better on cowpea while the Egypt strain develops better on an artificial diet.
During the oviposition experiment that both stains showed a clear difference in hierarchy of host
plants considered suitable for oviposition, where the Egyptian strain is significantly more
attracted to clover than the Benin strain.
Also showed with electroantennographic recordings and significant values was the higher
sensitivity the Egypt strain had towards (E)2-hexenal, (E/Z)-b-ocimene, (Z)-3-hexenyl acetate,
Nonanal, (-)-linalool and ?-myrcene when compared to the responses from the Benin strain..
Starkare i samhället - Om invandrarföreningar som en social resurs för politisk integration
This paper examines the consequences of membership and participation in immigrant associations on individual immigrants? political integration and indirect political participation with reference to Swedish society. The theoretical underpinnings consist of a social structural outlook on social capital, combined with the Civic Voluntarism Model, both of which focus on the potential role of social networks for moving people into political action. After a presentation of parallel qualitative data over the experiences of individual members in a Finnish and Bosnian-Hercegovinian organisation, it is suggested that immigrant associations support the political integration of their members into the host society. Firstly, the case studies indicate that members of immigrant associations gain the opportunity to augment their civic skills, which is a significant prerequisite for political participation.
Växtinventering och skötselåtgärder : en studie av Rektorsgårdens trädgård i Uppsala
The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.

Prion infection of ovine cell culture with a natural Swedish scrapie isolate from 1986
Scrapie is an infectious neurologic disease in sheep caused by prions, corresponding to transmissible spongiform encephalopathies (TSEs) in other species. The prion is presumably constituted of PrPSc, the misfolded form of the normal endogenous prion protein, PrPC, which is found in practically all cells in the body. PrPSc can induce a conformational change in PrPC and misfold it as an imprint of itself; this is how prions amplify and spread. The process of conformational change is poorly understood and there might exist intermediate forms between PrPC and PrPSc. Bioassay using mice has traditionally been the golden standard in prion studies but is limited by cost and time.
Svenska företags etableringar i Sydkorea och Japan : En jämförande studie av den koreanska och japanska marknaden
South Korea is one of the fastest growing economies of the world and experts claim that it?s headed towards the same direction as Japan. This doesn?t imply that the countries are similar to an extent where companies don?t have to consider the differences while entering the host market. This study was conducted for the purpose of giving a view of the business climate in the countries and thereby could help companies who see the countries as potential host markets.
En jämförelse mellan får- och nötkreatursbetade hagmarker med avseende på populationsstorlek samt artsammansättning hos dagfjärilar och örter
Many of Europe?s day-living butterflies have shown decreasing populations during the last decades and many species are threatened. Many butterflies are dependent on managed semi-natural grasslands because of their richness in nectar sources and host plants for the butterfly larva. Swedish pastures are mostly managed through grazing. The number of cattle in Sweden have been decreasing while the number of sheep in the country increased by 30%.
Olfactory responses of the parasitic wasp, Trybliographa rapae (Hymenoptera: Figitidae)
Delia flies (Diptera: Anthomyiidae) are economically important pests in several horticultural crops. The control is commonly relying on chemical insecticides, though there are possibilities with biological control from the natural enemies in the field. An important natural enemy is the parasitic wasp, Trybliographa rapae Westwood (Hymenoptera: Figitidae) that lays eggs in the Delia fly larvae. The parasitoid larva and the host larva have a parallel development until the host dies within its puparium and an adult parasitoid emerges.
The aim of this thesis was to understand the attraction to host- and food-associated plant volatiles of T. rapae, in order to enhance the effectiveness of the parasitic wasp as a biological control agent.
Kan infektion med hjärtmask (Dirofilaria immitis) smitta i Sverige?
Infektion med hjärtmask (Dirofilaria immitis) är endemisk bland hund och katt i stora delar av världen, bland annat södra Europa och de flesta delstater i USA. I Sverige anses det i nuläget inte finnas risk för inhemsk smitta. Faktorer som klimatförändringar och förflyttning av sällskapsdjur inom Europa kan öka risken för spridning till tidigare fria områden. Denna litteraturstudie ger en översikt över hur smittspridning av Dirofilaria immitis sker samt hur dess förutsättningar ser ut i Sverige. För att smittspridning av Dirofilaria immitis ska kunna ske krävs närvaro av mikrofilaremiska hundar, myggor som fungerar som mellanvärdar och vektorer, samt ett klimat som tillåter utveckling av mikrofilarier till det infektiösa stadiet L3 i mellanvärden.
"Ett lugnt hörn när det är kaos i världen" : en studie om varför barnprogrammet Bolibompa ser ut som det gör under och dagarna efter en katastrof
This study intends to examine why the Swedish children?s programme Bolibompa is produced the way it is during a larger catastrophe. Our intention was to find out how the editorial staff, in the children?s department in the public service television of Sweden (SVT),was handling the Estonia disaster, the September 11 attacks and the Asian Tsunami. To accomplish that, we first had to find out how the children?s programme looked during these catastrophes and also understand how the editorial staff was working with children?s programme during ordinary days.To achieve our purpose we have been interviewing five persons from SVT, who was involved in producing the children?s programme during these three catastrophes.
"När jag blir stor vill jag jobba som...." : Om genusmedvetenhet och vägledning i skolans tidigare år
Vår studie, som omfattar sex intervjuer, fokuserar på genusmedvetenhet hos vägledare. På vilket sätt de arbetar med genus i mötet med elever för att vidga perspektiv och på vilket sätt de kan tänka sig att arbeta med att skapa en genusmedvetenhet hos elever i år 4-6. Vårt resultat visar att genusmedvetenhet är ett svårt begrepp som har olika betydelse för vägledarna. Vägledarna menar att de inte arbetar på ett planerat genusmedvetet arbetssätt idag men vi ser att de omedvetet arbetar med genusperspektivet genom olika aktiviteter. I arbetet med elever i år 4-6, vill vägledarna bidra på olika sätt med att vidga elevernas perspektiv gällande självuppfattning, yrken och arbetsmarknad.
För mig är mobbning rädsla, ensamhet men framför allt osäkerhet : flickor och pojkars syn på mobbning
AimThe aim of this study was to examine the views on bullying in the context of physical education among pupils studying at intermediate level through a gender perspective.The following questions where used in the examination.In what ways does the views on bullying differ between girls and boys?How is bullying manifested during classes in physical education?How do girls and boys experience cross-gender and same-gender bullying?MethodThe study is based upon a survey with questions of both quantitative and qualitative disposition. A total of 210 pupils from areas in and around Stockholm participated in the study, all studying at intermediate level. The participants consisted of 92 girls and 116 boys (two declined). The selection of participating schools where made out of convenience.
Ibland känns det nästan som ett övergrepp - en studie om språkets betydelse i omsorgen för invandrare med demens som bor på särskilt boende
Purpose/aim: My purpose is to illustrate the significance of the language in communication with immigrants having a different native language, who suffers from dementia. The three main questions have been:How important is the native language in the communication with immigrant who suffers from dementia?What consequences can happen for the immigrant who does not understand Swedish? How can we use the salutogenesis point of view to create satisfactory care for immigrants who has difficulties to make them self understood in the Swedish language? Material/method: I made qualitative interviews with staff working in nursing homes with dementia care. I also searched scientific articles and other findings in this area of science. Main results: The best care for immigrants with dementia is nursing homes where the staff speaks the immigrant?s native language.
