Verktygsanvändning som miljöberikning för gulbröstad kapucin (Cebus xanthosternos)
That animals should be able to express their natural behaviours, even in captivity, has become a more important issue lately. Nowadays Zoos work much more with educating people and helping conservation projects for endangered species. This is two important reasons for making the environment as natural as possible for zoo animals. Both in captivity and in the wild capuchin monkeys have been seen to use tools such as stones and sticks to get food and are therefore seen as a natural and important behaviour for them.
This study was carried out to evaluate a specific sort of environmental enrichment where a group of three capuchins had to use sticks to get different kinds of food out of bottles.
Källskatt på utdelning till utländska pensionsfonder : Kupongskattelagens förenlighet med EU-rättens fria rörlighet för kapital
In the school subject of the natural sciences it is imperative that the students are given opportunities to ?talk science?, since the dialogues that occur in the classroom have a significant importance for the students? abilities to engage in meaning-making in their learning process. Hence, the student and teacher interaction in the classroom and the feedback given there play a significant role in the students? learning process. The aim of this study is to contribute to the development of formative assessment tools that can mediate the students? meaning-making in natural sciences subjects in upper-secondary school.
Restoring biodiversity in degraded secondary rain forest in Sabah, Malaysia : natural regeneration of trees after restoration treatments
Many tropical rain forests has been lost or degraded as a result of human activities and environmental factors. Since the level of biodiversity is high in the tropics, maintaining these areas is of great importance. Forests like these are often assumed to benefit from forest restoration and rehabilitation. The INIKEA project area in Eastern Sabah, Malaysian Borneo, aims to improve biodiversity and/or species richness in the degraded forest through enrichment planting with indigenous species. The objective of this thesis was to evaluate how different treatments (liberation, gap-cluster planting and line planting) affect the biodiversity of natural regeneration in different forest types in the Rain forest Restoration Experiment, located in the INIKEA project area.
Föräldrars utbildningsnivå : En studie om hur elevernas prestationer som påverkas av föräldrarnas bakgrund
This study is about how students 'performance in school is influenced by parents' educational background. The study has been performed by cooperation with two schools in Stockholm. One class in each school has participated and the students have amongst other questions answered regarding their grades in natural science subjects. To examine whether parents 'educational background affect students' performance, a quantitative survey in the form of poll has been conducted. Even a literature review was conducted in this area to get a clearer picture of how parents' educational background affects the performance of students.This study shows that students who have academic parents perform better than students who have not got academically educated parents.
Utformning & placering av vädringskanaler i ett passivhus, drivet av naturliga krafter
A passive house in Norra Djurgårdsstaden drawn by Tengbom Arkitekter is going to be built. A shaft for airing is needed for a few apartments in the house.The airing shaft is designed for a few two room apartments in the house, which are not able to achieve satisfactory airing, as their outer walls are facing a single direction. The other apartments on the same floor are corner apartments. These apartments do not have the same difficulty with airing since they have their outer walls in different directions, with different pressures at the facades. The airflow in the airing shaft is supposed to be driven only by natural forces, by the sun. The purpose of natural driven forces is to achieve low energy consumption for the house.In this thesis, a design of the shaft for airing has been developed.Initially an open shaft for all apartments was analyzed.
Kålgallmygga, Contarinia nasturtii Kieffer : en växtskadegörare på kål
The purpose of this paper is to examine what problems cabbage growers have with the
Swede Midge. The last few years the Swede Midge, Contarinia nasturtii, has become
a larger problem for cabbage growers in several countries in Europe as well as in
Sweden. In Canada the problems are so severe that the midge is classified as a
quarantine pest and therefore certain rules have to be followed. I have collected facts
of the biology, host plants and reproduction of the Swede Midge, as well as the
growers experiences and the occurrence of the midge in Canada, Europe and Sweden.
The Swede Midge is hard to control because of its short life cycle and the larvae are
protected between the heartleaves of the plant. When the larva feeds on the growth
point the plant becomes distorted, in some cases several heads develop or none at all.
When the midge infests spring rape its flower buds become undeveloped and rosette
like.
Samband mellan tidig ålder vid avskiljning och missriktat diande hos föl :
By tradition horses are weaned at an age of 5-6 months. This study illuminates weaned foals misdirected suckling behaviour, which means that they try to suckle another foal. Since no information about this issue is presented, we decided to perform a behaviour study on weaned foals. The misdirected suckling behaviour was studied on a group with 7 foals, with both fillies and colts. In the group the weaning age varied between 147 days and 215 days, and the first time we observed them, they had been separated from the mares for 12 days.
Urmakarens budbärare : Modern intelligent design-rörelse i jämförelse med brittisk naturteologi vid 1800-talets början
I uppsatsen jämförs William Paleys Natural Theology : or, evidence of the Existence and Attributes of the Deity, collected from the appearances of nature från 1802 med Michale J. Behes Darwin's black box : The biochemical challenge to evolution från 1996. Jämförelsen kontextualiseras med en skiss över evolutionsteorimotståndets historia under den mellanliggande perioden, som tillsammans med själva den vetenskapliga utvecklingen, antas förklara de skillnader i tilltal och val av argument som föreligger mellan de två verken. I fråga om grundläggande budskap, idéstruktur, syfte och religiositet befinns de två verken ligga varandra betydligt närmare än vad som initialt kan tyckas vara fallet..
Sex skogsägares upplevelser av stormen Gudrun: en expolrativ studie
In Sweden we are spared from large natural disasters. However, in January 2005 part of Sweden was struck by a hurricane. It did not only leave a decimated landscape in its wake. It also left its mark on many people who lived in the south of Sweden. In this paper the reader will be presented six qualitative interviews that build on forestowners' experiences during and in the aftermath of the Storm of January 2005.
Sverigedemokraternasanvändning av begreppet?svenskfientlighet? : en diskursanalys
The Sweden Democrats uses a term to describe a situation where ?swedes? are being discriminated against by other ethnic groups and where the elite is promoting this. The term ?svenskfientlighet? can be translated as ?swedofobia? and in this thesis a speech by the party leader Jimmie Åkesson held during the election campaign that solely was dedicated to this term is being analyzed with the help of tools developed by the scholar Ruth Wodak. Ruth Wodak has previously analyzed the rhetoric by other European right-wing-populist parties like FPÖ in Austria and has asked for other researchers to analyze the speech used by right-wing-populist and extremist parties to get a better understanding for just how these parties construct their different enemies.
Barns utevistelse på förskolan : Utemiljöns inverkan på barns lekar och naturintresse
Through interviews with children of ages 4-5 years old and by observing children children at play at three preschools with different types of outdoor surroundings, I have investigated if the preschools outdoor surroundings have any influences on the children´ choice of play. The hypothesis was that natural surroundings can entice children´s interest in nature being in it and play. I have also investigated if the children know why it is important to be outdoors and if they know it has a positive influence on their health.The result of my investigation is that the children play about the same games at the three different preschool gardens, but at the preschool with more natural surroundings, the children have more contact with plants and animals, and could learn of the different phenomena of nature by the preschool teacher answering their questions. Most of the children in the interviews know it´s useful to be outdoors and be on the move and get fresh air, but many of them thought it was most important to play. By being outdoors the children get exercise, fresh air, play and at the same time they establish an understanding of the nature and a healthier life..
Behuggning av betongytor: ett test av hantverksmetoder
During the latter half of the 18th century, when concrete started seeing general use in
modern cities, the use of different methods to give the concrete a finished surface texture
saw use. One of these was using different methods of mechanically altering the surface using
a slew of cutting and crushing techniques with mallet and chisel. This was done in order to
hide the often dull and gray look of concrete, and allude to other more expensive and
luxurious stones. The work would possibly have been done by experienced stonemasons,
using much of the same techniques and tools they would have used while working natural
stones. Or did they? This essay explores, through the use of traditional handcrafts and tools,
the claim that the working of concrete surfaces can be done with the same tools and skillset
as the working of natural stone.
Indianen och kalla kriget : Audiovisuella representationer av kalla kriget 1965-1986
The similarity between the Russian and the Indian, in a Cold War context, may be ambiguous considering the ethnic-social variables and the period in time from where the Indians relate. However, by analyzing these, as well as other, characters in the exhibition of movies, we could learn something about the ideology of the time from which the movies derive.This study examines ideology and movies in the Cold War era and concludes that the Indian, for example, may be representing the values of the common public enemy, originating from the Cold War ideology. The movies examined, regardless of influence of distinct Cold War themes or lack of such themes, carry attributes that give evidence of typical Cold War ideology. The fear of communism and common enemies connected to a Cold War context, the thought of America as the land of the free ? with the horizon in the ending of the movies as metaphoric to freedom ? and the moral rhetoric that connects to the American thought of a duty as a global savior, are all signs of the Cold War ideology.Even though the messages are somewhat clearer and more distinct in the movies with Cold War motifs, the fact that ideology is projected through other movies as well should be considered essential for the continuing study of movies as cultural artefacts..
Hotet från de kriminella MC-gängen - en normativ studie av värdekonflikten mellan den personliga integriteten och statens säkerhet
The aim of this essay is to illustrate a fundamental question; what is a democracy allowed to do to protect itself from enemies? I´ve chosen to analyze the conflict between the two values; individual integrity and state´s security. The individual integrity refers to every person's right to have a protected sphere, and the stat´s security refers to its right to protect itself, and these two positions are often time incompatible. This conflict of value is shown in a normative analysis, where depending on which perspective or normative logic is seen as primate, it gives different conclusions to what a democracy should do to defend itself.To demonstrate how severe the threats are against the society, I choose to examine a specific part of the organized crime, the outlaw motorcycle gangs. They have a special position in affecting the legal system because they have an explicit aim to influence the judicial system with scaremongering and threats.
LEKKROKAR- ?Något att hänga upp leken på?
The research of today shows that natural environments are importantfor children's physical and mental development. It alsoshows that children often opt out of the traditional equipmentplaygrounds have to offer. By breaking the boundary betweenthe playground and park, is it possible to create a new spacethat will encourage rather than demand play? Through gatheringinformation and talking to landscape architects, designers,and children, I realized that today's parks already have environmentsand objects that could be used for playing. But whatthey need is something that makes the environment even moreinviting for children to play.
