Det finns tre arter zebror i världen ? stäppzebra, bergszebra och Grevyzebra. Bergszebran och stäppzebran har dessutom en del underarter. Grantzebran är en underart av stäppzebra som lever i östra Afrika, bl.a. i Kenya.

Departing from Fred Dretske?s groundbreaking article, this essay explore the epistemic closure principle: the principle that states that knowledge is closed under known implication. It also explores the relationship to skepticism, various attempts to challenge and defend the principle, as well as developing a new perspective where the skeptical premise is seen as an a priori justified tautology that can be overriden by a posteriori experience. I argue that Dretske?s illuminating example makes it clear that there is an unescapable choice between either rejecting a skeptical premise ? however intuitive it may seem ? or inextricably having to admit a skeptical conclusion. .

Den här uppsatsen undersöker hur identitet uttrycks i tre musikvideos som tillhör genren ?queer rap? (Mykki Blanco, Le1f och Zebra Katz) där jag ställer frågan om den identitet som uttrycks hos dem är subversiva. För att ta reda på detta användes representations-begreppet tillsammans med Richard Dyers definition av stereotyper och José Esteban Muñoz avidentifikations-begrepp.Dessa tre artisters identiteter går att tolkas som subversiva då de använder normer och redan befintliga identiteter för att skapa nya uttryck, både från det heteronormativa och andra subversiva subkulturer. De skapar nya identiteter och uttryck med de normer som finns..

Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.

Well-functioning bicycle paths are relevant issues in today´s society as a way to increase active transport. Active transport means working for a better global climate, urban environment and public health. What we experience on a bicycle affects the choice of a bicycle path and is a subject where there is much left to explore. This essay examines methods in environmental psychology literature that measure the experiences of landscape. The aim is to find and apply methods to measure the experience of two bicycle paths in the Skåne plains.

Sofia Hedberg: "Wut is Wut?" En studie av maskuliniteter och sexualiteter inom hiphop-genren. Uppsala universitet: Institutionen för musikvetenskap. C-uppsats 15 hp. 2013.This essay examines how a group of male, homosexual or bisexual African-American rappers from New York City are challenging the norms of hypermasculinity and heteronormativity within the musical genre of hip-hop.

In this thesis, I enquire into how the USA ? our world?s wealthiest and most powerful nation ?  and its federal government has dealt with two of its most severe natural disasters: the drought and dust storms that plagued the Great Plains during the 1930?s, i.e. the Dust Bowl, and Hurricane Katrina, which made landfall in late August 2005. I attempt to identify differences and similarities and analyze if and, in that case, how the hegemonic politico-economic paradigm affected the federal management of these crises. This comparison is made relevant by the fact that two differing paradigms were at play during these events. In the thirties, President Franklin D. Roosevelt launched his ?New Deal?, a series of counter cyclical measures in line with the Keynesian school of economics, as a response to the overwhelming economic depression as well as the raging drought.

Många gående skadas eller dör i trafiken varje år. En stor del av olyckorna inträffarvid övergångsställen, flest olyckor sker vid obevakade övergångsställen. Nollvisionenär ett långsiktigt mål att ingen människa ska behöva skadas eller dö itrafiken. Somett ytterligare steg mot  nollvisionen infördes år 2000 den så kallade?Zebralagen?, en lag som innebär att fordonsförare har väjningsplikt gentemotgående.

In East Africa live two species of Griffon Vultures; Rüppel?s Griffon Vulture (Gyps rueppellii) and African White-backed Griffon Vulture (G. africanus). One of the apparently most important factors limiting the population of these birds is food supply. Griffon vultures nest for eight months of the year, and are during this period geographically tied down to the nesting place.

The thesis mission is to investigate whether the swiveling laser that Vectura (former Vägverket Konsult) has in use to measure the road areas and straddle measuring can be used to detect differences in the reflective road markings function. This is to increase use of the swiveling laser and get rid of the manual measurements performed today.Currently, the measurement of road markings reflective function is performed with both mobile and handheld measuring instruments. The purpose of this thesis is to develop better methods for determination of road markings? reflective function, in order to facilitate the description and suggestions for improvements of the maintenance of road markings reflective function.The questions that the thesis has been to start with are:Can the swiveling laser detect differences in longitudinal and transverse road markings reflective function?The accuracy of measurement has been sweeping the laser over the reference instrument (LTL-2000)Is it necessary with a conversion factor for swiveling laser data against the reference instrument data?To answer the question 2 and 3, there has been a field work in Värnamo where a road stretch with longitudinal road markings and zebra crossing (transverse road markings) has been investigated with a swiveling laser and LTL-2000.The formulas and calculations contained in the thesis are drawn from scientific reports that are produced by VTI in Linköping. The same formula that was used to calculate the optical measurement data was also used for the swiveling laser data.

ABSTRACT Skånskt Naturbeteskött is a group of approximately 30 beefproducers in the south of Sweden, who sell their products on the local market. They are certified with Svenskt Sigill, an organisation that works with animal welfare, environmental responsibility, safe food, open landscape and independent qualitycontrol. These producers have to fulfil certain demands regarding pasture and quality of the meat. For this essay I did a market investigation in which I wanted to find out what qualities the Swedish market and the consumers want in their beef. The purpose was to find out what Skånskt Naturbeteskött could do differently to satisfy the market for locally produced beef in the south of Sweden. In the investigation I turned to those responsible for the beef in 12 supermarkets, 4 selling Skånskt Naturbeteskött today, 4 that sold it before but quit, and 4 that never have sold it but might be interested in the future.
