This essay contains a discoursive analysis of fifteen travel reports from five of the largest papers in Sweden. The travel reports contains recaptions from wildlife tourism experiences were the predators are the main target, or at least one of the main targets. Seven of the reports are from Sweden and eight of them from Russia, Rumania, Finland, Turkey and the United States. Predators in this essay aims to those in Sweden called ?the big five?, these are: bears, wolves, lynxes , wolverines and golden eagles.

The aim of this thesis is to compare the effectivity of using a natural language and a controlled vocabulary when performing subject searches in the bibliographic database LISA Library and Information Science Abstracts. 20 topics were created and for each topic two searches were made, one by using a query formulated with natural language directed to the abstract field and the other one by using a query formulated with descriptors from the thesaurus in LISA directed to the descriptor field. The average relative recall amounted to 64,8% for the AB-queries and 54% for the DE-queries. Failure analysis showed that the majority of the relevant documents not retrieved by AB-queries could have been retrieved with other query terms, such as synonyms. In a natural language there are many different ways of expressing a topic, and this tends to have a negative effect on retrieval effectivity.

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.

Knowledge about feed racks for feeding forages to horses is lacking. Racks for sheep and cows are sometimes used for horses. Feeding roughage on the ground, or feeding silage bales with the plastic and net still on, can bring on a lot of different problems. The opportunity to control the hygienic quality is small and feed losses can be high. The purpose of this experiment was to investigate how the eating behaviour and consumption of horses were influenced by feeding racks of different constructions. Feed losses and changes in chemical composition of the forage were also studied.

This final project includes an analysis and a programme proposal for the area Bergsbrunna södra. The area is situated along the railway between Uppsala ? Stockholm, just south of Uppsala city. A new railway station is planned here, which make the area attractive as residential area. There are several values to take into consideration when developing an area. An extensive analysis and valuation may define and protect different characters and values, and also find the places most suitable to build upon. The area consists of three separate characters of landscape: the wide open cultivated fields, the hilly wooden ground and the more varying little valley. There are visual, cultural, social and ecological values to preserve. The south part of the area is woods with high natural values that borders to a national park in the natural forest of Lunsen.

Natural disasters are becoming more common due to climate change and it is important to adapt the society and its infrastructure to withstand events such as extreme rainfall. Precipitation is an important climatic factor affecting the transport and annually generates the cost of millions in damages, over the past 40 years heavy rain has increased and will continue to increase in the future. The extreme rainfall that occurred in Kramfors municipality in September 2013 led to flooding and destroyed several roads, including highway 90, which recently both had been rebuilt and given a new stretch of road. Extreme rainfall had also occurred in the municipality earlier.  The aim of the thesis was to examine how the Swedish Transport Administration handles new knowledge gained after natural disasters and how this is used in the planning of new roads.

The aim of this thesis is to describe the subject indexing of images performed at the provincial museum of Jämtland and to evaluate the inter-indexer consistency at the museum. The main questions are: How are photographs indexed in the database SOFIE foto regarding Outline-codes, subject headings and natural language keywords? How does these procedures compare to research and indexing projects? How consistent are the indexers at the museum when choosing Outline-codes, subject headings and natural language keywords? Answers are sought by reading articles about classification, image indexing, indexing language, indexing consistency and by looking at a number of projects attempting to standardise image indexing practice in Sweden. The indexing practice at the museum is also described. In addition a minor inter-indexing consistency study, based on the subject indexing of ten photographs made by five indexers at the museum, is performed.

The aim of this study is to find out if the former students think that they have made use of the courses they have taken at the Natural Resource Use Programme specialised in Animal Husbandry at Lillerudsgymnasiet or if the courses should be exchanged. In the study it is assumed that a course can be useful professionally, for further studies and in private life.The main questions are: Have the former students made use of the courses they took at the Natural Resource Use Programme specialised in Animal Husbandry at Lillerudsgymnasiet? Was it the right decision to replace the course Horses?I have sent a questionnaire to all the students who graduated between 2003 and 2007. Out of 107 questionnaires I received 66 replies (62 %). All students have studied the same mandatory courses but different eligible courses.

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.

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.

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.

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.

There are several objects of age whose provenance and history has disappeared with time. The purpose of this thesis is to find out which analyzing methods that gives results and how the different methods can be combined and /or established in each other. The investigations centers around an embroidery, belonging to Tämta church, with unknown origin, use and age. The embroidery is long and narrow with applications in the form of dragons and eagles on a ground of velvet cloth. The dragons and eagles are covered with metal threads.
