The influence of active bomas on habitat choice of the common warthog (Phacochoerus africanus)

The common warthog (Phachocoerus africanus) is a relatively long-legged pig with noticeable curved tusks, a short neck and three pairs of facial warts. It has four recognized subspecies. The common warthog is a non-migratory ungulate living on the African savannah. It is a hindgut fermenter and predominantly dependent on high-quality foods. It prefers open areas for grazing but use bushes for cover.

A screening for Schmallenberg Virus among sheep and goats in Tanzania

Schmallenberg virus (SBV) is a novel arthropod-borne orthobunyavirus emerging in Europe in 2011 to 2012. Acute SBV infection causes diarrhoea, fever and reduced milk production in dairy cattle, but it is mainly the reproductive disorders (abortions, malformed foetuses and stillborn animals) in ruminants that have caused substantial economical losses. The prevalence of the virus outside of Europe is poorly investigated. SBV or SBV-like antibodies were detected in Mozambique in 2013, which raised interest for a similar study in Tanzania. In this study in Tanzania, blood samples were collected from 478 sheep and goats from 39 herds in 15 different villages in three districts, covering areas in the north, south and east of Tanzania. The epidemiology of the virus was investigated by tracing antibodies by ELISA and mapping of the virus by PCR was started.

Osteokondros hos tjur :

Several bulls in Sweden are culled because of lameness. Studies of beef bulls have shown that osteochondrosis is an important underlying cause of hind limb problems (Persson, 2003; Dutra, 1998). Osteochondrosis in horses, dogs, swine, poultry and man are well documentated in the literature, but there are few studies in cattle. The prevalence of osteochondrosis in dairy bulls in Sweden is unknown. The aim of this study was to investigate the presence and localisation of osteochondrosis in the hindlimbs of dairy bulls. This study consists of 48 one-year-old bulls divided into four groups related to which farm they came from.

Informationskompetens och användarundervisning i en sydafrikansk universitetskontext

The purpose of this Master?s thesis is to study howuniversity librarians in a South African context relate to theconcept of information literacy. We investigated differencesand similarities in approaches to user education andinformation literacy. We have based our study on thefollowing research questions: What are the prerequisites foruser education at the University of the Western Cape? Howdo these prerequisites influence librarians' approaches toinformation literacy and user education at the University ofthe Western Cape? We have used a sociocultural theoreticalperspective and Hofstede's cultural dimensions in orderto pay particular attention to the cultural and social contextof user education.

"Action speaks louder than words" EU, jämställdhet och EPA-förhandlingarna

Officially, the EU gender policy since 2000 has been guided by the strategy of Gender Mainstreaming. This strategy aims to promote gender equality and is informed by a feminist ontology which stipulates that women are structurally subordinated.In this essay, I examine whether the European Commission has adequately adhered to this gender policy in its free trade negotiations with the ACP (African, Caribbean, and Pacific) countries as part of the Cotonou Agreement. As a result of my text analysis of documents related to the negotiations, opinion pieces by interested actors and policy papers of the EU, I find that the Commission does not act in accordance to its stated gender policy.To explain this discrepancy between policy intent and actions, I employ postliberal feminist theory and Robert Putnam's Two-Level Game Theory Model. By analyzing statistics and published research, I explore how gender issues are being represented politically on a domestic and international level.My findings show that a key cause of this discrepancy lies in the low levels of female participation in the political institutions of the EU and ACP; a lack of participation that is especially pronounced in the area of international economics. In explaining the constraints on female participation and the prospects of full implementation of the EU's gender policy in the international political economy, I emphasize the role of culturally and historically gendered institutions..

Warden i småskaliga krig : Luftoperationer under Sydafrikanska gränskriget

Konflikterna i södra Afrika under 1900-talets andra hälft är något som idag är främmande för många och som direkt för tankarna till apartheid regimen. Hårt pressat av omvärlden på grund av deras raspolitik kämpade Sydafrika i många år en oftast anonym konflikt mot kommunistiska styrkor som hade stöd från Kuba och Sovjetunionen.Under vissa perioder, speciellt mot krigsslutet, eskalerades stridigheterna och stora konventionella operationer bedrevs långt in i Angola för att hindra framfarten av fientliga styrkor.  Sydafrikas användandet av stridsflyg kopplas i denna studie till John A. Warden III:s teorier om hur luftmakt bör användas.Warden är mest känd från perspektivet att hans teorier var grundläggande i planerandet av Gulfkriget i Irak och andra amerikanska luftoffensiver under 1990- och 2000-talet. I detta arbete undersöks i hur stor utsträckning det är möjligt att finna spår av Wardens luftmakts-teorier i Sydafrikas gränskrig.Resultatet av studien visar, genom en analys, hur enskilda händelser och operationer korrelerar med utvalda begrepp ur Wardens teorier. Däremot finns det inga indikationer som pekar på att det större strategiska perspektivet överensstämmer med Wardens större konceptuella idéer..

Bilder från det inre Afrika : Representationer av afrikaner i den svenska skämtpressen 1880-1920

This paper investigates the representations of Africans in the Swedish comic press around the time 1880-1920, with the purpose of establishing how Africans were depicted and how these representations can be explained. The sources consist of four comic magazines: Kasper, Söndags-Nisse, Strix and Naggen.Results show that images of Africans in the late 19th and early 20th century Swedish comic press highly conform to international representations. Traditional stereotypes and overall caricatures are widely applied, mediating racial difference and black subordination. The comic strips and jokes can be divided into categories, defined by their main theme: 1) Exotic animals and nature 2) Skin colour 3) The unintelligent or uncivilised savage 4) Cannibalism 5) The civilised African 6) Imperialistic overtones. The use of international stereotypes indicates that some comic strips might have been directly copied from foreign publications, and incorporated into Swedish contexts.Several theories, likely interacting, can be considered in explaining the imagery.

Kulturell identitet i En halv gul sol och Atlantens mage : En postkolonial läsning av två icke-västerla?ndska romaner

This study analyses two non-western novels used in the subject of Swedish in upper secondary school: Fatou Diomes The Belly of the Atlantic and Chimamanda Ngozi Adichies Half a Yellow Sun. Looking at how the books female main character relate to Stuart Halls theory of cultural identity, I come to the conclusion that they somewhat differently relate to an essential ?authentic? self. Salie talks explicit about a generic African soul that she possesses. Olanna never talks about anything ?authentic?, but her narrative and contrary subject positions can be read as a way of demasking her European ?white? self in favour of a truer Igbo self.

Temperaturmätning på gris - en jämförelse mellan infrarödmätning på hud och rektaltemperatur

Under en tidsperiod på tretton veckor mättes temperaturen på tvåhundratjugo suggor och etthundraåttiotre smågrisar i grisningsboxar vid SLUs forskningsanläggning. Vid varje mätningstillfälle mättes rektaltemperatur samt hudtemperatur på tryne, öra, bog, länd och vulva. Varje mätområde på huden mättes tre gånger vid ett mättillfälle, två olika IR-termometrar användes. Detta innebar totalt ettusen etthundra enskilda mätningar på suggor och niohundrafemton mätningar på smågrisar. som samlades in och analyserades avseende korrelation mellan de olika mätområdena på huden och rektaltemperaturen.

Afrika och den eurocentriska diskursen: En analys av globala perspektiv på afrikansk historieskrivning

Den här uppsatsen utgår från hypotesen att även om de stora imperierna kom att falla sönder under efterkrigstidens decennium så kom det koloniala systemets maktstruktur att leva kvar genom den globala, kapitalistiska världsmarknaden; och detta har i sin tur påverkat den ekonomiska och politiska utvecklingen av Afrika i en negativ riktning. Den eurocentriska diskurs som konstruerar en verklighet där Väst uppfattas som ett ?facit? kom med andra ord inte att försvinna i samband med de koloniala imperiernas fall. Materialet som uppsatsen fokuserar på är framför allt artiklar publicerade i Journal of African History mellan år 2000 och 2010. Den här uppsatsen dra slutsatsen ? här presenterad i breda drag ? att det är väldigt få undersökningar som har problematiken kring det eurocentriska perspektivet på Afrikas historia som sin utgångspunkt.

Piglet mortality in commercial piglet production herds

Dödfödda grisar och smågrisdödlighet under diperioden leder till både produktionsförlust och innebär dessutom försämrad djurvälfärd. Förluster orsakade av dödfödslar, smågrisar som kläms ihjäl av suggan och som svälter ihjäl kan förebyggas genom god skötsel, bra djurstallar ochavelsurval. För att lyckas med detta krävs att riskfaktorer för smågrisdödlighet kan identifieras.Syftet med den här studien är att undersöka variationen i förekomsten av dödfödda smågrisar och dödligheten under digivningsperioden beroende på kullnummer, kullstorlek, säsong och besättning. Ett andra syfte är att fastställa om det finns någon upprepbarhet för suggor vad gällerförekomst av dödfödda smågrisar. Data erhölls från fyra kommersiella grisbesättningar, belägna i centrala Sverige, som använder sig av besättningsövervakningsprogrammet ?PigWin Sugg?.

Pojkars inställning till dans : En studie i Sverige och Sydafrika

This work has been to find out what attitude the boys have towards dancing. To gather material conducted interviews with four boys from Sweden and four boys from South Africa to examine the boy?s attitude towards dancing. I wanted answers if the gender, culture or generation has an effect on the boys' attitude to dance. Two interviews were made with a teacher in Sweden and one in South Africa, which had responsibility for dance lessons at the school.

Förekomst av leukocyter i råsperma hos semingaltar :

Detection of leukocytes in semen from boars is part of the routine control of semen quality. Leukocytes in semen can cause damage to spermatozoa that leads to impaired fertilization. In the artificial insemination (AI) industry there are standard routines for the quality control of the boars and of the neat semen before use. Since 2001, Quality Genetics has not done the leukocyte examination on semen samples from boars which are used for the production of pigs for slaughter. The purpose of this study was to investigate the occurrence of leukocytes in semen from AI-boars. The questions addressed were whether there are boars that have leukocytes in their semen and how frequently it occurs and, moreover, if there are differences between breeds, or even between individuals whose semen was checked before use in AI-dose production compared to those which were not. The study included a total of 135 AI-boars, of which 67 were Hampshire, 35 Yorkshire and 33 Landrace, all belonging to Quality Genetics AI-station in Hållsta.

Försvarad eller försvagad demokrati? : En intervjustudie om hur globaliseringen har påverkat demokratin i Kenya.

The main purpose of the examination research project is to analyze and describe how democracy and globalization is understood when they are integrated in the developing country of Kenya. This has been reflected by interviewing Kenyan teachers in history and government, to receive their view on globalization and its affects on democracy. Another purpose is to discuss this in didactic terms as a way to see how it can be practically used for upper-secondary schoolteachers in the subjects of civics and social studies. The procedure of the project and the method of use are interviews that have been analyzed in all with theoretical perspectives. My queries to be answered for the research are:1.
