Entreprenöriellt lärande och entreprenörskap : En studie av hur naturbrukslärare upplever undervisningssättet

This thesis deals with how natural resource teachers in natural resource schools in Sweden work with entrepreneurial learning and entrepreneurship. It is important both for our Government and our agricultural department that entrepreneurship is present in our education. In government´s new reform 2011 for upper secondary schools entrepreneurship is the main theme, but it is not only entrepreneurship as a business company, it is also about entrepreneurship in schools like entrepreneurial capabilities in government´s writ. The purpose of this study is to examine how a number of teachers in natural resource schools are working with entrepreneurial learning and entrepreneurship. I have also asked how the teachers would like to work with these areas.The method I have chosen to use in order to perform this study is qualitative interviews with six natural resource teachers and a pilote interview.The teachers I interviewed are working to provide students with self-knowledge and teaches students to see possibilities and solve problems, which is required for us to create entrepreneurial students and entrepreneurship in education. This is also stressed in several of the literary sources I used..

Övergång till helkrossballast : En studie för Strängbetongfabrikerna i Veddige och Herrljunga

This exam report has been developed in association with Strangbetong AB, Sweden.The natural gravel that is being used as fine aggregate for concrete production today is an ending natural recourse and the Swedish government has decided to strongly reduce the extraction from the year of 2020. The only reasonable replacement is aggregates from crushed rocks but this material has other properties than natural aggregates. The concrete manufacturers now have to learn how to use these new fine aggregates in a cost effective way in order to ensure the quality of their concrete production.In this project, crushed aggregates and combination of crushed and natural aggregates have been tested with existing formulas for fresh concrete. The two parameters yield stress and plastic viscosity have been measured which gives a good description of the workability of the fresh concrete. Different methods to make measurements on the dry fine aggregates, has also been tested, to find out if there is any correlations between these parameters and the parameters from the measurement on the fresh concrete..

Sköldpaddsdammen som en naturlig oas på Mallorca : en fallstudie

This study shows how to plan a pond with an ecosystem which although it will have turtles living in it will not need to be cared. I will also demonstrate how this pond would be designed to work in the natural landscape on Mallorca. The background to the study is that I am interested to investigate how plants that we in Sweden are using as indoor plants are growing in their natural landscape and how to build a land-scape with them. The study highlights different cleaning-systems that can be used to clean a pond in a natural way. A comparison will be made between the conditions of an exterminated turtle-species which will live in this environment and a species that is easier to care for.

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.


Hur mycket naturbetesmarker har vi idag? : skattning av areal via nationella, stickprovsbaserade inventeringar samt jämförelse mot befintliga informationskällor

To reach objectives within EU?s Habitatdirective and the national environmental objectives, more information about semi-natural pastures is required. The expression semi-natural pasture is used for pastures that during the latest time are uncultivated and unfertilized. Semi-natural pastures are important in many respects for example to conserve the biodiversity and for our cultural history. The aim of my study was to compile and calculate the area of semi-natural pastures by use existing sources of information.

Naturlekplatser :

This study is essentially based on my own questions concerning contemporary playgrounds. Why are they so unimaginative? What do the children say about them? Is it possible to create playgrounds less constructed, and with more natural elements? This report starts with references to literature studies, personal references and my personal view, and ends with a suggestion for a physical solution for an actual day care centre. The aim is to learn more about how the natural environment affects children, the importance of playing, and try to use this knowledge in a design of a day care centre. My main theme can be summarized in the following question: Why is natural elements in playgrounds considered to be healthy for children? I wanted to create a playground with natural characteristics which I myself would have appreciated as a child.

Naturkatastrofers inverkan på bankers aktiekurser : En eventstudie

Objective: Our purpose with this study is to demonstrate the impact of natural disasters on banks' share prices.Method: Quantitative survey method, an event study.Conclusion: There is no association or a very weak correlation in this study between natural disasters and the Swedish banks' share prices..

Stenmjöl eller naturgrus i betong : En jämförande studie

 The objective of this thesis is to examine the difference in workability in fresh concrete, when crushed fine aggregate replaces natural gravel. The shape of the fine aggregate,  packing and flow of six crushed material and three natural materials will be determined by easy studies, the results will be compared with a slump cone test..

Naturskolan- en metod till lärande? : Outdoor teaching - A method for learning?

The purpose of this essay is to find an answer to whether the methodology used by the Naturskolan conduces to learning and also if the Naturskolan, as a method of its own, leads to an increased interest in natural science for the pupils participating in the classes at the Naturskolan.The method which has been used to reach the results of the study is a quantitative opinion poll. The results reached through the study has been compared to previous research in the subject. Deeper studies were made to examine however the interest of the pupils was influenced by their visit at the Naturskolan.The results of the study show an increase of interest in natural science after visiting the Naturskolan. It also shows that the teachers? interest in natural science and outdoor pedagogy has increased by the visit at the Naturskolan.Through this study we came to the conclusion that the Naturskolan is a good method to learning..

Kontrollerad vokabulär eller naturligt språk? En empirisk studie.

The question whether controlled vocabulary or natural language free-text terms is the most effective search strategy has occupied researchers in LIS for many decades. This Masters thesis is an empirical study which aims to compare these two search strategies in LISA Library and Information Science Abstracts, an online bibliographic database. 22 topics from the discipline of Library and Information Science were constructed and out of each topic one query for each search strategy was formed. Queries in natural language were formed with terms from different sources, for example dictionaries, while queries in controlled vocabulary were built with terms from LISAs electronic thesaurus. The measures used in this study were precision, relative recall pooling method and overlap.

Do prey-animals in zoos need predators?

Today is one of the goals with zoos to conserve endangered species and some animals may also become reintroduced. But behaviours can change in generations of captive animals because of environments that differ from the wild. Animals must then be prepared before being reintroduced and predator training enhances the animal?s chance to survive in the wild. When training animals to avoid predators it is often necessary to use frightening stimuli.

Echoing nature - A design of an exhibition concept based on a natural phenomenon as a model to explore and learn

In the project Echoing Nature i have searched a design for an exhibi¬tion concept. That visualizes the natural phenomenon of self-assem¬bling materials in a simplified way. My question is, how can you emo¬tionally re-connect the modern man to nature and raise awareness. I assume my thesis that the experience of a natural phenomenon can inspire us to see a bigger context, provoke curiosity and generate an initial sense of belonging to nature. The result is an interactive sculp¬ture that consists of 3-dimensional Tetris blocks.

Open Archives Initiative om "öppna arkiv" och den sociala kontextens betydelse

There is an ongoing evolution in scholarly communication. The traditional way of communicating scholarly results through scientific journals is beginning to be replaced by other means of dissemination. One new channel for scholars to communicate their results is digital publication in so-called open archives. An open archive is a kind of full text database, where a scholar may archive/publish his or her articles, as a complement or a substitute to publishing in scientific journals. There are discipline-oriented archives and institutional archives.
