Do prey-animals in zoos need predators?

Today is one of the goals with zoos to conserve endangered species and some animals may also become reintroduced. But behaviours can change in generations of captive animals because of environments that differ from the wild. Animals must then be prepared before being reintroduced and predator training enhances the animal?s chance to survive in the wild. When training animals to avoid predators it is often necessary to use frightening stimuli.

Tecken : En retorisk-semiologisk analys av antirökreklam

This essay studies how advertisements in various anti-smoking campaigns can influence and persuade by using anti-logos as counter-arguments to the tobacco industry's logos. In contrast to tobacco advertising arguments such as freedom (logos), pleasure (pathos) and trademark (ethos) the anti-smoking campaigns create anti-logos arguments with various connotations such as repulsive pictures and sexual implications to influence groups of people not to start smoking or to quit smoking.Advertisement of tobacco does not exist nowadays due to legal restrictions in the western world; however several decades of myths created in the consumer consciousness still exist. Thus one can speak of a tobacco advertising ideology that exists and the various anti-smoking campaigns trying to change that ideology.The purpose of anti-smoking campaigns is to conduct a kategoria of myth that tobacco advertisement has created over the years. Anti smoking organizations do this by creating a new ideology to affect consumer?s attitude toward smoking and the tobacco myth with an anti-myth.

Klämtar klockan för Klippans kommun? En studie i rasism och antirasism

The subject of the essay is about a society called Klippan and the existing conflicts there between an active racist group and some youths with foreign heritage. The essay also concerns issues like racism, its effects and how it is expressed at different levels in a society. Futhermore we discuss how a community can prevent 'subtle' racism and open declared racism and how to work in a racist manner. We also talk about which role the immigrant youths play in the conflicts and how their behaviour can be understood. Another perspective that is discussed is which aspects can affect individuals to join an active racist group and which factors can make them leave such a group.

I strävan efter anti-estetik och musikalisk etik

In his master thesis, Johan Jutterström pursues an anti-aesthetic and ethic artistic process. He?s using mainly three different strategies; reasoning through text, composing for ensemble, and solo improvising on the saxophone. Through composing the piece for 12 musicians Trästolen, Jutterström tries to erase himself and his taste from the music. In that endeavor he looks to physics as a catalyst.

Kan fiskpredation reglera populationer av storspigg (Gasterosteus aculeatus) i Östersjön?

Fiskbestånden i Östersjön har sedan början av 1980-talet genomgått en omfattande förändring. Stora predatorer, som torsk (Gadus morhua) och abborre (Perca fluviatilis) har minskat i antal medan det finns tecken på att storspigg (Gasterosteus aculeatus) har ökat. Denna sannolika ökning av storspigg skulle kunna ha att göra med minskningen av både torsk och abborre som predatorer i de kustnära tångbältena. För att undersöka detta utfördes ett mesokosmexperiment där torskens och abborrens förmåga att predera på storspigg undersöktes, både i ljus och mörker. Hypoteserna som arbetet utgick ifrån var att torsk var en bättre predator i mörker än i ljus och att torsk var en bättre predator än abborre i mörker.Resultaten visar på att torsk är den bättre predatorn i både ljus och mörker, samt att den är lika framgångsrik i mörker som i ljus.

Predatorinducerad fekunditet hos Daphnia pulex vid simulerade årstidsbundna temperaturvariationer

Female growth, number of eggs and egg growth of Daphnia pulex were studied at four temperatures, 12, 16, 18 and 20°C. I hypothesized that female growth and number of eggs would be lower and the size of the eggs larger in the presence of a predator (kairomones) than in its absence. This effect was expected to be more evident at lower temperatures. I could not find any effect of kairomones on female growth, number of eggs or egg size, although there was a weak tendency for an effect on number of eggs. There was, however, an effect of temperature, regardless of predator treatment (i.

Information, makt och konspirationsteorier : En studie av informationskritiska användare

Purpose?This study has examined the information behaviour and perception of information in a group ofinformation users who have a critical approach to the media and the information supply. Some of them call themselvesor are being called conspiracy theorists.

Optimering av sampling quality-parametrar för Mental Ray

Fotorealistiska 3d-bilder används idag inom ett brett spektrum av branscher. Framställningen av denna typ av grafik kräver ofta väldigt mycket datorkraft. Vid rendering med renderingsmotorer som använder sig av raytracing algoritmer är aliasing ett medfött problem. Lösningen heter anti-aliasing som arbetar för att undvika aliasing artefakter som jagged edges eller Moiré-effekter med mera. En del av anti-aliasingprocessen är supersampling som ofta kräver mycket datorkraft.

Effects of brown bear (Ursus arctos) odour on the patch choice and behaviour of different ungulate species

The return of large predators to regions where they were previously extirpated has created a need for knowledge about their effect on prey species, not only their lethal but also their behavioural or risk effects. In this study the behavioural risk effects of brown bear (Ursus arctos) were tested on fallow deer (Dama dama), roe deer (Capreolus capreolus), red deer (Cervus elaphus), moose (Alces alces) and wild boar (Sus scrofa). This was done by using patches of fur to simulate the presence of the novel predator (brown bear), a novel nonpredator (reindeer (Rangifer tarandus) and no fur as control. These three treatments were then compared. The response variables measured were increased vigilance, decreased feeding time and change in patch use.

Stigmatisering av depression och dess inverkan på vårdsökandeprocessen ? En litteraturstudie

Sverigedemokraterna i Ronneby : Teorikonsumerande studie med fallet i centrum

With varied electoral success for anti-immigration parties across Western Europe, Sweden is often held as an example where anti-immigration parties have been less successful. This have caught the interest of many scientists around the world and have recently developed theories on a subnational level when testing Sweden?s municipalities, on why they have failed here but not in other countries. But in the election to 2010, Sweden now joins the rest of the Western-European countries in having an anti-immigrations party in the parliament.This paper has tested three theories on a Municipality that has shown evident support for the Sweden democrats, both in the local and the national election. This is done with a qualitative approach, made up from interviews with the local established parties.
