Människans roll i skogslandskapets trädslagssammansättning, en studie i Ångermanland

Human presence has always influenced the surrounding areas, the forest as well. Structure and species composition have changed during human land use. Knowledge regarding these changes should be of great interest for conservation and forestry. We have analyzed human impact on the tree species composition on five study sites during 2000 years in Ångermanland, Sweden. More specifically the change in tree species composition in percentage amongst alder, birch, spruce and pine over time.

Betydelse av lövinslag, död ved och variation i träddiameter för artrikedomen hos småfåglar

Forest management contributes to the changes in forest structure by turning heterogenous forests of varied age into homogenous forests of similar age and thus affect bird species depending on different structures or habitats which are lost during forestry. In this report, a study was made to investigate how the amount of decidious trees, dead wood and variation in tree diameter affect bird diversity. The purpose of this study was to be able to give forest management guidelines to increase bird diversity. This study was conducted by investigating 65 transects in forests of different structure south of Linköping, Sweden. Along the 65 transects, birds were inventoried as well as the vegetation.

Mångfaldsarbete, en intersektionell strategi? : En studie av kommuners kombinerade jämställdhets- och mångfaldsplaner.

The purpose of this essay is to investigate and analyze the term diversity in five Swedish municipality?s combined gender equality- and diversity plans. The purpose is also to investigate who or whom of the employers that are included in the term diversity and if gender equality is included in the diversity work. The material is analyzed on the basis of theory of intersectionality and discourse analysis. The outcome of the analysis indicates that the municipalities use the term diversity in many different ways in the combined gender equality- and diversity plans.

Structure and tree diversity of lowland limestone forest on Seram Island, Indonesia

There have previously been very few studies of forests on Seram Island in the Eastern Indonesian archipelago and none before on lowland limestone primary forests. The COLUPSIA project on collaborative land use planning has therefore chosen Seram as one of two project sites. The objective of the COLUPSIA project is to establish collaborative and equitable land use planning. In order to achieve its objective the COLUPSIA project aims to improve understanding of traditional resource management and how it interacts with governmental systems, as well as enhancing knowledge about tropical landscapes and ecosystem services.The aim of this study was to contribute to the COLUPSIA project through describing lowland limestone forest on Seram Island in respect to (1) forest structure, (2) tree species richness and (3) tree species composition. We set up 5 plots, each of 0.2 ha, at one site, Mawalai, and collected data on tree variables (tree diameter ?10 cm) as well as for some other life forms and environmental data.

Mångfaldsarbete i skolans organisation och undervisning

The purpose of this thesis is to clarify the concept of ?managing diversity? and to describe how it appears in the Swedish school, in the classroom as well as in the organisation. To support the study, interviews have been carried out with principals and teachers in three different Swedish schools.The thesis is divided into two sections; a literature study and an interview section where we describe the thoughts and knowledge of principals and teachers. From a diversity point of view, we discuss the relationship between documents, organisation and teaching.The study described in this thesis shows that managing diversity has not yet had its break-through in a Swedish school context. The official curriculum of the Swedish school system values diversity, although the directives are unclear as to how the managing of diversity is to be carried out in reality.

Jag trivs bäst när havet svallar, och måsarna ger skri : En textanalytisk studie av biologisk mångfald i läroböcker

Biological diversity is one out of four dimensions, characterizing the subject of Biology ac-cording to the school curriculum. As a concept, biological diversity had its break through at the UN environmental conference in Rio de Janeiro in 1992, where the convention about bio-logical diversity, named CBD, was signed. According to the convention, almost all the na-tions of the world have engaged themselves to preserve the national diversity of species, in-cluding the diversity of genetics and ecological systems.This thesis focuses the biological diversity from the perspective of school books. The aim is to find out how the biological diversity is presented in biology books for students aged 12-15 years.In 1994, the current Swedish secondary and high school curriculum called LPO-94 was pre-sented. The biology books used in this study were published between 1994 and 2007, all of them exist in many editions and are published by three different publishers.The conclusion of the study is that all the biology books that were examined have reached different levels of the development in the field of biological diversity..

Det är en mångfald i fråga om mångfald : Personalvetare och PAO-studenter samtalar

This is a study of the discussions and sense making that HR-professionals and HR-students present concerning the phenomenon of diversity, through the theory of social representation.Our purpose is to study the reasoning around the phenomenon of diversity and what meaning HR-students and HR-professionals create around it. This study also attempts to examine how HR-professionals and HR-students reasoning and interaction differ from each other. In this study we have used the qualitative method of social representation through focus groups.The common themes found in the data material were the meaning of the phenomenon diversity, how the work with human resources can be connected to the phenomenon of diversity and diversity as an issue in society. The main result in this study was that we found a wide range of meaning put into the word diversity by the participants and that the individuals in the focus groups actively strived for consensus..

Datering av röta i hålekar :

I have chosen in this work to examine which factors are affecting the artificially creation of a tree cavity containing decomposed wood. The purpose of the work is to find out which factors are affecting the most when a tree cavity is created, and to apply these results when you artificially try to create a tree cavity. The need to create tree cavities comes from the situation where many tree cavity living beetles finds themselves today. When existing trees are to pass out there will be no suitable inheritors yet. The work was initially to focus on cavities created from cut branches.

Det enskilda trädet som meningsbärare : erfarenheter av två trädplanteringsprojekt i Helsingborg

Individual trees can act as carriers of meaning. When a person attributes deep meanings to a specific tree, a relationship between the person and the tree is created. To avoid conflicts between users and planners, increased awareness is required of how important individual trees may be to a person. The objective of this study was to elucidate persons? relationships with individual urban trees.

En inventering av säregna trädformer funna i Sverige

In Sweden and in Scandinavia the amount of tree species are rather few. However many different forms of trees arise due to mutations and gives rare appearances like cut-leaved and hanging forms. In some cases these trees are interesting as cultivars and a few of them have become popular garden trees. The knowledge of the original trees and early propagation is meagre.In this study a selected group of trees were found through search of literature. Eight tree forms were chosen and investigated in situ.

Vad är Mångfald? : En studie om lärare samt ledning i två skolor i olika delar i

The subject of this paper is to examine the view of diversity among ten teachers and three principals in the Swedish compulsory school. The purpose is to investigate how they relate to the diversity and in what ways it is involved in their work.The French sociologist Pierre Bourdieus basic ideas of habitus, capital and field are used as a theoretical starting point. The study is mainly based on interviews supported by literature in the subject area.The findings show that diversity is associated with ethnicity among all informants. The drawn conclusion is that this is partly due to the mediated picture but also since ethnicity mainly serves as a starting point in the literature..

Tee Tree Oil - Ett effektivt behandlingspreparat i tandvården?

Tea Tree Oil eller TTO som det förkortas, är en olja som utvinns ur en australiensisk buske vid det latinska namnet Melaleuca alternifolia. Oljan har sedan många år använts som antiinflammatoriskt och bakteriedödande ämne. Denna litteraturstudie gjordes på 13 artiklar som svarade på tre sökningar i databasen PubMed. Artiklarna påvisar att TTO har en viss antibakteriell förmåga och kan fungera som antimykotiskt medel, men fler in vivo studer behövs för att säkerställa TTO:s effekt på olika parodontala åkommor..

Olika tidningar - Samma nyheter? : En studie i homogenisering

Less diversity and more homogenization in the media`s news range is the subject for our bachelor thesis. By analyzing and comparing three separate weeks in two of Sweden's largest evening newspapers Aftonbladet and Expressen we wanted to discoverhow the diversity between the two newspapers had changed over the years, more precisely from 1993 until now. Had there been a homogenization or not? We wanted to study this because it is a long going debate about the news stories becoming more and more the same. An important debate because less diversity in news events and news presentation may lead to less diversity in public opinions and knowledge.
