USA och Indien: ett växande strategiskt partnerskap och makt som balanserar

The study focus on the development of the bilateral relationship between India and the United States and the Next Step in Strategic Partnership (NSSP) from 2004 and the change in U.S. approach to India's neuclear program. With the rise of China to potential great power status I argue that the cooporation between the two is an act to balance the Chinese influence and to prevent future rivalry and a Chinese dominance of the East Asia. For the study I have used concepts and theorys from the realist tradition, in particular theorys of Balance of power and alliance forming..

Parasitering på en expanderande art : har kartfjärilen undkommit sina naturliga fiender?

Warmer climate is a driving factor to species expansion northwards. Expansion to new areas can result in escape from natural enemies, resulting in reduced levels of mortality and thereby potentially increasing the rate of expansion. The most important parasitoid species attacking butterfly larvae belong to the families Tachinidae, Ichneumonidae and Braconidae. The aim of this thesis was to investigate parasitism and difference between populations in established area and newly colonized area for the European map butterfly, Araschnia levana, in order to examine if the butterfly has escaped from some natural enemies. In 1982 the first European map butterfly was observed in Sweden and has now established up to middle Småland.

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.

Non-Identity. Att undkomma ett moralfilosofiskt moment 22

Can we harm future people? According to our commonly used contractarian theories, it seems we cannot. This is because our actions of today not only influence what they are supposed to influence, but also who mates with whom and when, and thus which particular persons will ever live in the future. Had we not performed a particular action, the future people born as a result of that same action, would not have been born. It therefore seems they cannot reasonably reject our actions.

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.

Nordisk identitet i förändring 1990 - talets försök till en nyartikulering av den Nordiska identiteten

The thesis analyzes the making of Nordic identity after the cold war which brought an end to Nordic exclusiveness of emphasizing ?soft power?. A need for a revitalization combined with an effort to enter History as an active subject, created constructivist project of a narrative style.My study relies on contemporary literature, focusing mainly on the construction of Nordic identity and regional cooperation in the 1990: s.I argue that Nordic identity was, and still is, determined of its comparable weakness in regard to the superpowers of the cold war, and, nowadays, to the EU.The architects of establishing a new Nordic identity, able to challenge a new Europe, fails in their effort, and what is left of their endeavour are separate states, each following their own agenda..

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.

Varför blev det fred i Indonesien? ? Kan rational choice förklara fredsuppgörelsen??

The conflict in Aceh had been going on for 30 years time, but ended after a tsunami hit the area in 2004. The impact the natural catastrophe had on the conflict was that both GAM and the Indonesian government was brought together with the intent of reaching a peace agreement. The authors to this thesis paper ask the question of why it became peace after such long time of war, but also if rational choice theory can explain this event. The answer to the first question is that the tsunami was the main reason to why it became peace. As to the second question, the conclusion would be that, depending on which view of human nature one has, rational choice theory can only answer the question if cultural, religious and emotional factors are disregarded.

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.
