Kalvningsintervall hos svenska köttkor : finns det genetisk variation som kan användas i avelsarbetet?
The Swedish beef cattle population is growing when the dairy cattle become fewer. The fertility of the beef cows is important for the profitability in beef cattle production. Today there is no genetic evaluation for female fertility in Swedish beef cows. The purpose of this study was to see if calving interval can be used in the genetic evaluation as a measure of female fertility in beef cows. For this purpose the variation in calving interval for beef cows of different breeds and ages registred in KAP was studied.
Styrelsesammansättning och lönsamhet i svenska aktiebolag
In this thesis we examine the relationship between board composition and firm performance in Swedish companies. The selection of companies includes all Swedish limited liability companies, with the exception of micro enterprises, that have been active between the years of 2009-2010. We develop hypotheses based on resource dependence theory, agency theory, and the resource based view, and test these with regression analysis against collected data. Specifically, we examine the effects of board diversity, outside directorships, and CEO duality. Our findings show that none of the theories provide sufficient explanatory power of the relationship between board composition and firm performance, and that further research is required to better understand the role and effects of company boards..
The genetic background of oxytocin and its importance for maternal behaviour of sows
Oxytocin is today widely spoken of as a "feel good" hormone. Recent research has increased interest in the hormone and its role in social and sexual interactions, as well as its importance for complex behavioral patterns. There is evidence that oxytocin is released during physical contact and is said to suppress anxiety and stress. In animals and humans, oxytocin, which is a neuropeptide and likewise a hormone, is necessary for parturition and lactation. Synthesis of oxytocin occurs in brain neurons and in specific organs involved in reproduction.
Habitat diversity and composition among growing wild boar (Sus scrofa L.) populations in Sweden
The wild boar (Sus scrofa L.) has expanded across Europe and Sweden in the last decades. It is a generalist species which utilizes a variety of habitats, and its presence has been shown to have both positive and negative effects for people and the landscape they are in. The abundance and increase of wild boar has previously been shown to differ between counties in Sweden, but there have been few explanations as to why.
In this study, I investigated correlations between the per capita rate of change (r) among wild boar populations in Sweden and a variety of different habitats on the county level. I also investigated if fragmentation per se or in certain habitats could be associated with the wild boar?s per capita rate of change.
My results show that fragmentation/diversity per se was not correlated with wild boar r.
Genetic parameters affecting leg length, leg weakness, hip- and elbow conformation in domesticated dogs, in comparison with pigs
Genetic parameters for four leg conformation traits in dogs (Canis lupus familiaris) are in this literature review summarized to investigate whether selective breeding could be useful to improve purebred dogs´ health and welfare. The four traits are leg length, leg weakness, hip joint and elbow joint conformation. When summarized, the genetic parameters are compared with genetic parameters affecting in pigs (Sus scrofa). Of the four traits, hip and elbow conformations were mostly studied in dogs. However, these traits were not widely studied in pigs.
När och varför dör smågrisarna under diperioden?
The purpose of this study was to compile when and why piglets die during the suckling peri-od. Piglet mortality is an important factor influencing the profitability of piglet production. There are many factors that play a role and interact whit each other. This study summarizes when the piglets die during the suckling period and reasons why the piglets die. The infor-mation given is crushed, illness, management/environmental, genetic influence and piglet birth weight/farrowingprocess.
British Airways - en mångfaldssaga?
British Airways (BA) kritiserades på 1990-talet för att vara en diskriminerande och fördomsfull organisation som exempelvis uteslöt kvinnor och färgade från pilotstyrkan. Idag hyllas bolaget som en föregångare inom mångfaldsarbete och mångkulturalitet. I uppsatsen studerar vi dels hur långt BA har kommit i sitt mångfaldsarbete på systemnivå och på operativ nivå, dels vilka faktorer som drivit på eller hindrat mångfaldsprocessen. Vi kommer fram till att BA idag uppfyller de flesta kriterier för att kunna kallas en multikulturell och inkluderande organisation. Att BA:s mångfaldsprocess har gått snabbt beror bland annat på att hindren för mångfald främst låg på systemnivå.
Genetic variation in dairy cattle claw health traits recorded by claw trimmers
Claw health has been recorded by claw trimmers at trimming in Sweden since 1996, but data was then captured at each AI association. From 2003 data was captured by central scanning and entered directly to the national cow data base at the Swedish Dairy Association (SDA). This reporting was introduced because SDA wanted to be able to use these records to improve dairy cow claw health by breeding. It is desirable with cows that have healthy claws, because poor claw health can contribute to impaired production and fertility.
The claw health report begins with some information about herd, claw trimmer, date et cetera and continues with the part where the claw health is recorded. Here the ID of each cow is filled in and on the same row the conditions for dermatitis, heel horn erosion, sole haemorrhage and sole ulcer are recorded as no lesion (blank), slight lesion (/) or severe lesion (X).
Mångkulturell bibliotekariekompetens - En litteraturstudie och intervjuer med bibliotekarier och chefer vid Malmö stadsbibliotek.
The title of this Master´s thesis is Multicultural librarian competence - a literature study and interwievs with librarians and managers in Malmö Public Library.Every fifth Swede is born abroad or has at least one parent who are. The migration flows of today reach out longer, there are more efficent ways of communication and travel. This has made previously ethnic homogeneous populations as the swedish more and more hetergeneous. Library services to inmigrant users started out as a specially directed activities. The political view of migration has changed over the years and the current perspective is the one of mutual integration and cultural diversity.
Skadegörelse klotter nedskräpning förbjuden : Graffitiborttagning som ikonoklasm
This essay concerns graffiti, and in particular graffiti removal regarded as iconoclasm.Graffiti is described as a visual symbol laden with both negative and positive values, and sometimes as a meaningful expression in the urban public space. One problem with graffiti as a field of study is the diversity of both the meaning of the term as well as the diversity of the phenomenon itself. Therefore I have defined the term graffiti as follows: words and images painted on public walls by a person usually in an unauthorised manner. Specific examples of graffiti and related phenomena are presented. Within the Swedish anti-graffiti discourse the pejorative term klotter (scribbling) is used to describe what I above define as graffiti.
Var är min frukost? : En studie av hur elevers övergång till gymnasiet och idrottsinriktad studiegång påverkar elevers frukostvanor
According to the national curriculum guidelines for elementary school, preschool and after-school 2011, (i.e. Lgr11), the Swedish school is based on a democratic foundation. Schools should prepare students to develop an understanding and acceptance of cultural diversity not only in the society as a whole but also how this should be reflected in the morals and ethics between us. The purpose of this study was to describe how teachers in multicultural schools perceptions and experiences on teaching pupils with diverse immigrant origin, and how they apply these cultural expression in practice.In particular, I focus on four teachers in multicultural schools and how they reason about applying cultural expressions that are transmitted at these schools and by them. Explicitly, I review how from policy documents and their own personal pedagogic are reflected in the actual teaching.
Artificiell insemination av får
AbstractThe purpose of this bachelor thesis is to describe the use of artificial insemination (AI) in sheep and discuss the possibilities for AI in Sweden. Male and female fertility, heat detection, semen handling and insemination techniques in sheep are described. Advantages and disadvantages of AI are discussed. In order to achieve genetic progress it is important with well planned and implemented breeding programs. The Swedish Sheep Recording Scheme and computer software from Elitlamm are the basis for sheep breeding in Sweden.
Kulturella värden, tro, levnadssätt och livsstil : faktorer som påverkar sjuksköterskans möte med muslimska patienter
There are over 1,5 billion Muslims living on earth and the religion is one of the world´s most increasing. Sweden is a country with a cultural diversity where about 300 000 Muslims lived in 1999. Today, the requirement for knowledge about caring for Muslims and the need of culturally competent nursing care are increasing.The aim of this study was to define cultural factors which the nurse has to recognize to be able to give culturally competent care to the Muslim patient. The method that has been used was a The Sunrise Model, which illustrates Leininger´s theory of culture care diversity and universality, provides a theoretical framework for the study. The results are presented on the basis of Leininger´s three cultural factors; cultural values, beliefs and lifeways.
Wild boar paradise : What makes the Swedish wild boar reproduce more or less successfully?
Due to the growing wild boar (Sus scrofa L.) population in Sweden there has been an increase in wild boar related traffic accidents, damage on cropland, and conflicts regarding the management of the wild boar. Knowing what makes the wild boar reproduce and survive more or less successfully in different geographic areas is an important part of managing the population. According to previous studies the wild boars rate of increase varies from county
to county. The aim of this study was to test, on the county scale level, if landscape composition and diversity as well as people and hunter densities might be the reason for this
variation. The first hypothesis was that a big proportion of forests and cropland would increase the rate of increase.
Vågar du satsa på kulturell mångfald- Har du något att förlora?
Vi lever idag i en allt mer globaliserad värld, vilket bidragit till ett mångkulturellt samhälle. Dagens organisationer står i och med detta inför utmaningen att anpassa sig. Utmaningen med mångfald är, att trots skillnader, lyckas samarbeta. Genom samspel och god kommunikation formas människan in i den sociala miljön på arbetsplatsen. Denna studie undersöker medarbetarnas attityder till och upplevelse av sin organisations kulturella mångfaldsarbete.
