Återhämtningsförmåga efter en stressupplevelse hos röda djungelhöns (Gallus gallus) och domesticerade värphöns, White Leghorn : Ett projektförslag för ämnet biologi på gymnasiet

Många elever ser naturvetenskapliga ämnen som svåra och tappar lätt intresset om inte läraren presenterar ämnet tillfredsställande. Jean Piaget har haft stor betydelse inom pedagogiken, då han menade att intelligens är en metod som barn kan lära sig genom att utforska och laborera. Genom möjligheten att få göra en observationsstudie på höns kom tanken att omarbeta denna till ett etologiprojekt för biologiämnet på gymnasiet. Projektet innebär att eleverna får arbeta med en observationsstudie från grunden, och goda möjligheter finns att integrera andra ämnen i detta. Människan började domesticera höns för tusentals år sedan, en process där djur utvecklar ett adaptivt beteende till människan och dess miljö.

Vad skiljer domesticerade värphöns från de röda djungelhönsen (Gallus gallus) i återhämtningsprocessen efter en standardiserad stressupplevelse? : En studie med ett didaktiskt perspektiv

Tidigare studier har visat att domesticerade höns påvisar en lägre nivå av rädsla jämfört med förfadern, de röda djungelhönsen. I denna studie testades 18 domesticerade White Leghorn (WL) och 18 röda djungelhöns (RJF). Målet med studien var att studera återhämtningen för de båda raserna vid en standardiserad stressupplevelse. Försöket gick ut på att hönsen vistades i enskilda burar och blev efter ett dygn utsatta av en akut stress. Därefter startades observationerna omedelbart för att se när hönsen återhämtade sig och återigen började visa naturliga beteenden.

Höns återhämtning efter stress samt domesticeringens effekter : En biologisk studie med ett lärarperspektiv

Den biologiska studien har visat att värphöns genom domesticeringen förändrat och anpassat sina beteenden till att leva med människor. De har utvecklat en minskad rädsla för människor och en ökad stresstålighet. I denna studie har höns återhämtning efter en stressupplevelse studerats. För att se hur domesticeringen har påverkat återhämtningen jämfördes beteenden mellan raserna White Leghorn och red junglefowl. Frågeställningarna som användes för att undersöka detta var: Hur lång tid tar det innan höns återhämtar sina naturliga beteenden, ej stressrelaterade, efter en stressupplevelse? Finns det några skillnader i återhämtningen beroende av kön eller mellan raserna White Leghorn och red junglefowl? Resultatet visade inte på en specifik tid för återhämtning men på att en tydlig återhämtning förekom.

Kan svarta män älska vita kvinnor?

AbstractRelationships between white women and black men have become a topic of interest in various discussion forums. By examining different arguments within certain discourses, it becomes clear that discourses that have a distinct autocrat outline, i.e. a closed and declaring nature which excludes alternative discursive arguments, also define these relationships as different and deviant in comparison to relationships that does not encompass and include the constellation white women and black men. As a result of the use of autocrat discourses the white women and black men who enter into relationships are displaced and positioned as subaltern. A position which, on the one hand, allows for uninhibited criticism, but, on the other hand, and most importantly, it is a position from where they can be defined by others.

White-Collar Crime i Sydafrika: vilken inverkan hade makt- och regimskiftet?

Det senaste decenniet har Sydafrika genomgått enorma förändringar. Landet har lämnat det minoritetsstyrda apartheidsystemet och blivit demokratiskt. Att förändringar får olika följder är givetvis självklart, kanske relaterar de flesta till den kraftiga ökningen av våldsbrott. Det finns dock även en annan typ av brott som ofta kommit i skymundan i den nuvarande debatten det är s.k. White-Collar Crime, vilket jag har valt att undersöka i min uppsats.

White trash : En diskursanalys av SVTs Mia och Klara- karaktär Tabita Karlsson som stereotyp White trash och representant för föreställningar om etnisk svensk underklass

Mia och Klara- karaktären Tabita Karlsson är den ideala White trash-stereotypen. Hon är en deltidisarbetslös ensamstående mamma med tre barn med tre olika män.

Ovårdad och odisciplinerad, sedeslös, vulgär och agerar helt utan tanke på vad som anses passande av den rådande medelklassnormen. Med Tabita Karlsson som material presenteras de diskurser vilka utgör White trash-stereotypen med hjälp av diskursanalys enligt Laclau och Mouffe.

Alla barn är lika mycket värda : En kvalitativ studie om hur barn framställs i KappAhls reklamfilmer

I have written an essay called ?All children are equally worth - A qualitative analysis of how children are produced in KappAhls commercials?.The purpose of this thesis is to do a study of the swedish clothing company KappAhl?s commercials. My purpose is divided into three questions: With which clothing colours are girls and boys represented in the commercials?

The three commercials are named: 1, Back to school, 2, Children?s christmas and 3, KappAhl 3 för 2 på alla överdelar för barn (translation: KappAhl 3 for 2 on all children?s tops).

Snövit : från undersaga till bildberättelse

Snow White through Grimm and Disney - A Comparative StudyThis essay attempts to discern the differences regarding six Swedish versions of the fairy-tale Snow White and the Seven Dwarfs over a period of 150 years. Focus is placed on structural transformations through time and media according to the analytical theories of Vladimir Propp. Attention is also given to former research done on the impact of the fairy-tale on the child from a psychological and social point of view. Of interest is the historical background of the tale, commencing with oral tradition, and how this was dealt with by the Grimm brothers. Three of the versions used for this comparative study are variants of the Grimm tale, and three belong to Walt Disney productions, i.e.

Bland världsmedborgare och vita världar : en studie av relationen mellan vithet och solidaritet i fyra kvinnors berättelser om sitt arbete med immigranter

The aim of this essay is to examine the ambivalence that I consider work of solidarity carried out from majority position to be associated with, and whether it makes sense to understand the relationship between majorities and minorities involved in this work by using the concepts of race and whiteness. Through Ruth Frankenbergs work on white women and race I consider whiteness to be a racialized position, and through Sara Ahmeds phenomenology of whiteness, which describes racialization as made through the orientation of bodies, I investigate how this racialized position is shaped and maintained by the solidarity work. The study is based on qualitative interviews with four White women engaged in two organizations that works on integration of female immigrants through creating jobs in a cooperative and through educating in national and familial democracy. The work of solidarity told of by the interviewees seems to produce racialized notions about immigrated people of color, which acts as a counterpart to the whiteness that the interviewees themselves possess. At the same time, the work also challenge this binary division, especially by incorporating the non-white women in what in this essay is called "the white world"..

Det var livet att slåss, att alltid vara en krigare : En studie om unga i vit makt

We have studied the process of recruiting young people to the white power movement. With the help of theoretical concepts as Outsiders and Stigma, we have elaborated the purpose of the study. The focus of the study lays in finding out which elements contributes to adolescence seeking membership in white power, and furthermore what white power organizations offers young people, to attract them to recruitment. We also want to find out if it possibly lays a desire for communion, behind adolescences decision to join these movements, and also how the communion manitains within the group? To expand our knowledge in the field of White Power, we have taken note of a body of literature that deals with the current topic, and previous research that treats questions about subculture, community and recruitment.

Läppar röda som blod : En strukturell analys av kristna symboler i Walt Disneys och Rupert Sanders versioner av Snövit

Snow White is one of the most popular fairytales to our time. There has been much research on the subject. `Lips red as blood- a structural analysis of Christian symbols´ in Walt Disneys and Rupert Sanders versions of Snow White` by Emma Svanström aims not to give a final answer to how Snow White should be interpreted. But rather the objective is to examine two versions in the search for any possible Christian influences and changes in such over time. The two versions are Walt Disney?s Snow white and the seven dwarfs and Rupert Sanders Snow White and the huntsman.

Svenskdidaktik i (o)jämlikhetens landskap : en studie om språkutveckling, rasifiering och klass

Symbolic resources transform in to social power and material resources through the educational system. This entails that all students should have equal access to it.The essay compares Swedish didactics in ?immigrant? and ?white? schools, all situated in socio-economically underprivileged areas, analysing interviews with eight Swedish teachers about their didactics regarding restricted and elaborated language code.Understanding teacher?s work in the class room requires attention to the intersections between race and class, and of both to the distribution of symbolic resources in general.The essay finds that the practice of the? immigrant? school teachers differs from the ?white? school teachers?. The former are active, providing intellectual tools, scaffolding and driving force while the later choose a more passive attitude, letting students decide for themselves what to do and what goals to reach. Consequently ?white? schools allow the reproduction of unequal distribution of symbolic resources while practice in immigrant schools aim to compensate for disadvantages.Practice seems to win legitimacy by different sets of conceptualisations.

Vobb - familjevänligt eller företagsvänligt?

Work gets more seamless and the demand on workers increases because of changes in the labour market. Studies show benefits for workers and companies if the employee achieves a balance between work and family, a way to facilitate it is family-friendly policies. A study done by Unionen shows that three out of four white collar workers choose to vobba (working and caring for a sick child), which blurs the boundaries between work and family. Research on flexibility, organisational culture and gender structures shows how these aspects affect the balance between work and family. This is a study where seven white collar workers (three men) that vobbar and two managers (one man) were interviewed.

Kvickrotens reaktion på klippning och konkurrens i rajgräs- och vitklöverbestånd :

Couch grass (Elymus repens (L.) Gould) is a severe weed in Sweden, and since both the use of herbicides and cultivation should be decreased, it will become increasingly problematic to control couch. The present work is meant to, by literature studies and an experiment, give some answers to the question if cutting and competition can depress the growth of couch. The experiment was carried out in the growing season 2001 at Ultuna, Uppsala, in plastic boxes. The design was three-factorial randomised complete blocks. The factors were plant combination, nitrogen level and cutting strategy.
