Individuell tillväxt och substratval hos en lokalt differentierad population av Asellus aquaticus
Local differentiation may occur during a short period of time and is part of the formation of new species. The isopod Asellus aquaticus is an example of a species in which local adaptation has occurred during a short period of time. An establishment of stonewort (Chara spp.) vegetation in Lake Tåkern (in the 2000) resulted in two different Asellus ecotypes; a lighter pigmented, smaller one that lives among stoneworts grazing periphytic algae, and a darker, larger ecotype that feeds on decaying leaves in reed (Phragmites australis vegetation. The purpose of this study was to examine whether there are differences in growth between ecotypes, depending on whether the food was periphytic algae or leaves, and to study the choice of substrates between the two food types. For the study, animals from both habitats were brought in from Lake Tåkern to the laboratory.
Vi har i alla fall aldrig varit apor! : En postkolonial studie om kreationism bland unga
This case study examines how a group of upper secondary school students in a multiethnical suburb of Stockholm reason about the theory of evolution. The theoretical background of the thesis is postcolonial and the questions raised were how spread the creationist thoughts are in the group; in what way the backgrounds of the students are relevant to their thoughts; how the students construct the notion of the theory of evolution; how they position themselves and others in relation to the discourse of the theory of evolution; if there are any differences between students at the collage program of natural science and the collage program of social science, and in that case, what differences; and who or what inspires the young in their thoughts about the theory of evolution. To answer these questions both a survey poll and interviews were used. The result of the case study showed that a majority of the students at the investigated school has creationist ideas and that the students profiled on social science have creationist ideas in a wider extent. Another result is that the religious background seems to be relevant to develop creationist thoughts, while the variables gender, home district and educational level did not differ the creationist group from the whole group.
Kalcium- och fosforsmältbarhet hos växande hästar
In the latest edition of NRC (2007) the feeding recommendations for Ca and P to growing
horses were increased with 35 and 25 %, respectively, based on results from a Canadian study
showing that daily endogenous fecal losses of Ca and P were greater than previously
suggested. A Ca absorption efficiency of 50 % is used for all horses. However, the true
absorption efficiency might be as high as 70 % in young horses. P absorption efficiency is
assumed to be higher for growing horses because their diets are often supplemented with
inorganic P. Thus, an efficiency of 45 % is used for growing horses as compared to 35 % for
mature horses.

Skilda frälsare i samma kläder : En studie om Mithras och Messias funktioner och likheter
It has since long been noticed that savior figures from different religions have reminded of each other, and there are different theories trying to explain why. This study examines religions operating in the same culture, and in this case, judaism and zoroastrianism, and their influence on each other. In particular, focus is on zoroastrianism's image of the savior figure Mithra, and how this representation may have influenced the description of the Messiah in the Talmud. How are the two figures represented in the scriptures and what similarities can be identified?By a thorough content analysis the studie examines the Avesta of zoroastrianism and the Talmud from judaism.
Ett vidgat textbegrepp i praktiken : Fem lärare om undervisning utifrån ett vidgat textbegrepp
AbstractThis study deals with Swedish upper secondary school teachers' approaches to an expanded text concept. Attitudes mediated through media as well as ?the new languages? that media give rise to, imply new conditions for the activities in school. As a necessary adaptation to the new conditions given by the media forces, the Swedish upper secondary school 1994 incorporated ?an expanded text concept? in the syllabus for the Swedish language.The focus of the study is how Swedish upper secondary school teachers' work to meet and challenge the students' in an expanded text concept.
EU:s omställning till en hållbar jordbruksnäring
Cultivable land is a limited resource and agriculture contributes to some of the most serious environmental problems facing the planet like, global warming, eutrophication and loss of biodiversity. The specialized, industrial agriculture with monoculture and extensive input of external energy, commercial fertilizer, and chemical pesticides are all essentially unsustainable. An adaptation to other methods of production is necessary to preserve the environment for future generations. The aim of this study is to describe the factors that distinguish sustainable from unsustainable agriculture. The results will be used to examine if and how the European Union (EU) works in order to create a more sustainable agricultural industry and to analyze the preconditions for such development.
Makt och påverkan : Om att vara föreståndare i ett föräldrakooperativ
Den här studien bygger på semistrukturerad intervjuer med föreståndare inom föräldrakooperativa daghem för att analysera vad styrformen har för påverkan på ledarskapet och hur detta utövas. Bakgrunden till studien är en undran i varför föreståndare uppfattar relationen till föräldrar inom den föräldrakooperativa barnomsorgen som problematisk. Det grundläggande antagandet utgår därmed ifrån att själva organisationsformen med dess styrning utgör ett pedagogiskt problem där frågor som roller, makt och social identitet blir aktuellt i utövandet av ledarskapet. Studien har visat att såväl föreståndare som föräldrar innehar multipla roller. Detta leder inledningsvis till problem för föreståndaren som får svårigheter med att läsa av olika sammanhang och vad som förväntas av dem.
"AVRÄTTAS ej BENÅDAS" : en kvalitativ studie av migrationsmyndigheternas bedömning av synnerligen ömmande omständigheter i ärendena för sex funktionshindrade migranter
This study is aimed to increase the knowledge about the Swedish immigration authorities? assessment of the asylum applications based on particularly distressing circumstances, submitted by disabled undocumented migrants. Making an attempt to explain the reasons of asylum-seekers? health deterioration during the asylum process, this study determines the factors in migration authorities proceedings affecting such deterioration. Documents in five personal files concerning six disabled asylum-seekers, whose applications were declined, were studied by applying two observational methods: content analysis of the documents in the personal files and non-participant observations made during receptions of undocumented migrants at the Swedish Asylum Committee.
Agilt - men agilt nog?
This paper aims to investigate whether a small organization with small development teams can find a value in leaving a functioning development process to follow a formal systems development methodology, if these organizations can find support in an agile systems development method and in such case the method needs to be adjusted according to the organizations unique conditions.A traditional plan-driven system development methodology includes a number of phases that are carried out sequentially and a completed phase can basically not be resumed. All requirements are specified at the beginning of a project and at the end of the project only one delivery of software take place. This can cause difficulties in for example dealing with changing requirements. Agile system development methods intend to deal with changing requirements and to enable continuous delivery of valuable, working software.In this paper, both the traditional plan-driven methods and agile methods will be explained. Research methodology and existing system development theories will be discussed and a company where the study has been conducted will be presented.
Upprepade ljusstimuli orsakar interferens i mörkeradapterade elektroretinogram hos hund : en utvärdering av några av European College of Veterinary Ophthalmology´s rekommendationer för elektroretinografi på hund
Electroretinography is an examination method where the function of the retina is objectively assessed. In 2002 the European College of Veterinary Ophthalmology (ECVO) published a proposition to a standard on how to perform ERG examinations, to facilitate comparison of results and to make it possible to repeat examinations.
The purpose of this study was to validate parts of the canine ERG protocol suggested by the ECVO. Our principal aim was to study if there is any interference at the recommended stimulus intervals for dark-adapted rod- and combined rod-/cone responses.
The results show that there is an effect on the a- and b-wave amplitudes when different stimulus intervals are employed. When all examined intervals are pooled, there is an increase in the median b-wave to each consecutive dim, white (rod) stimulus in a series of four.
En annan stad är möjlig! : En studie om rätten till staden och urbana sociala rörelser i Hamburg
The right to the city has lately become the rallying cry for many urban social movements all over the world to challenge neoliberal planning, gentrification, the privatization of urban commons and growing spatial and social gaps in city and society. This senior essay studies urban social movements that in different ways advocate the idea of the right to the city. The term right to the city was coined in the late 1960s by French urban theorist Henri Lefebvre, who promoted the idea of the city as a common, a space belonging to everyone. The right to the city is not ?a return to traditional cities?, but ?a right to urban life? (1996:158).This study focuses on the city of Hamburg.
Ett anpassat ledningssystem för informationssäkerhet : - Hur gör en liten organisation med hög personalomsättning?
This paper aims to find out how to implement an information security management (ISMS) system that is based on ISO/IEC 27001-standard into a small organization with high employee turnover. The standard employs the PDCA-method as a course of action for implementing the standard. The reason for implementing such a system is to introduce information security to the organization and to maintain it despite the changes in management. The paper based it?s survey on a case study of a student nation in Uppsala, Sweden.
Medialisering i det politiska systemet: en kvalitativ studie om en politiskt styrd organisations medialiseringsprocess
AbstractPurpose: The purpose of this thesis was to examine to which extant the politically governed organization, Swedish association of local authorities and local regions (SALAR), has been mediatized. Furthermore the purpose was to examine how SALAR being a Meta-organization affected the mediatization process. To accomplish this the thesis studied how SALAR organized themselves internally in order to form opinion through the media in one of their prioritized issues. A further purpose was to equalize SALAR?s mediatization process with the mediatization process for the whole political system. Method: This is a qualitative study which the gathered material has been collected through two types of methods, semi structured interviews and field observations.Material: A total of eight interviews were made distributed over three departments inside SALAR.
Ronia the robber's daughter: an analysis of the translation of Ronja Rövardotter into English
The aim of this paper has been to examine to what extent it has been possible for Patricia Crampton, translator of Ronia, the Robber?s Daughter, to capture and cling to the very personal style in which Astrid Lindgren writes. I also wanted to find out if any adaptations of the text were made and, if any, how they have affected the tone of the book. To fulfil this purpose a thorough comparison of the original text and the translation has been made. The first chapter consists of an introduction presenting the background to my choice of topic and giving a short presentation of Astrid Lindgren and her career as an author.
