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..

Historisk markanvändning på Färsna gårds inägor och utmarker

Semi-natural grasslands are threatened biotopes in the landscape and without conservation measures high values of nature will be lost. Meanwhile, the biological values associated with cultural values of the traditional agricultural landscape in Sweden. Studies of land use history may help to understand how today Biological diversity has evolved and how it can be preserved. Färsna farm in Norrtälje has left some of the old heritage of Biological diversity in the form of nature - forest and grassland, which hosts an unusual herb-rich flora. Through the study of historic maps and från1673/1767/1801/1901 1952 and orthophoto of the area has a picture of how land use has changed over time emerged.

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.

Knista kyrkog?rd: ett rekonstruktionsf?rslag f?r den v?stra kyrkog?rden

This study focuses on a reconstruction proposal of a small part of a rural churchyard that has lost a big part of its history, in form of its conformation and plant material. The chosen part of the cemetery was established in 1938, and this proposal is an interpretation of the architect?s original plan, the workers wishes and my own observations and experiences of the place. In this proposal I have tried to balance the plants composition to create an environment that can benefit the Biological diversity, that fits the locations habitat and today?s maintenance.

Miljö- och Handelsgåtan : Intellektuella egendomsrätter och dess implikationer i en globaliserad verklighet

This paper seeks to discern the political factors that determine the results of negotiations in international cooperation. On the one hand, it makes a contribution to the broader theoretical debate on international regimes by combining regime theory and theories on globalisation into an integrated framework for the analysis of international policy results, or in this case treaties (theoretical objective). More generally, globalisation theory will help us understand why it has become important to initiate international cooperation, and regime theory to elucidate how these international cooperations emerge. To many observers, it is the large transnational corporations of the rich North, which have done best out of free trade. Through the huge influence they wield over governments at the WTO (World Trade Organisation), these corporations have won the freedom to move around the globe without restriction, making use of cheap labour, and locating wherever they can best tap into the largest and most lucrative markets.

Framtidens stadsträd för en fungerande grönstruktur

The effect of climate change places demands on how we build cities. Cities have to be built denser to meet the objectives of sustainability but as a result of this densification city green areas are at risk of exploitationand disappearing. The question this raises is whether there has to be an opposition between a dense and a green city?Urban trees are playing a very important role in cities. They stand as the major part of the vegetation in citieswhich are otherwise dominated with concrete and stone.

Sjuksköterskors upplevelser av möten med patienter från andra kulturer och deras närstående : en intervjustudie om smärta

Background: Many Swedish inhabitants origin from different countries with different cultures that may show pain in other ways than Swedes. The Swedish law stress that nursing care should be done individually according to the patient's capabilities and needs. Aim and Method: The aim of this study was to describe nurses´ experiences of encounters with patients from other cultures with pain, and also their next of kin. Qualitative interviews were carried out with seven nurses. The interviews were analysed with the starting point in Giger and Davidhizars Transcultural Assessment Model and the six phenomena: communication, space, social organisation, time, environmental control and Biological diversity.

Våtmarker i urbana miljöer : växtgestaltning och planering

The practice of landscape architectural involves forming the space in our cities and suburbs, as well as the landscape surrounding. The need of exploiting green environment leads up to, among other issues, flood problem during heavy rain and overfed water environments. The problem is partially caused by the shortage of knowledge, how the environment is responding of the innovations made by the city- urban planning and how to get sustainability. Research and knowledge how to take care of our environment, in a natural way, is increasing. The object of the thesis is to propose control and balance in urban wetlands, and discuss the difference a plant design can do. The thesis deals with discourses in the field of landscape architecture, Biological diversity, dam construction, limnology, planting design and management, pollution of the environment and urban design practice.

Evaluating six crop mixes used for game fields in southwest Sweden : biomass production, fallow deer preference and species diversity

Game fields are one way to divert animals away from sensitive areas, create shelter and forage, and also to increase the Biological diversity. In this study I investigated how the plant composition in six different crop mixes used for game fields affected the biomass production, biomass consumption and Biological diversity at the Koberg estate in southwestern Sweden. Six experimental fields were used and each field contained six plots, approximately 1500 m2 each, that was sown with a different crop mix. The crop mixes ranged from a pure grass mix (A), 70 % grass and 30 % leguminous plants (B), 53 % grass, 21 % leguminous plants and 26 % other herbs (C), 100 % leguminous plants (D) to the most complex mixes constituting of 91 % leguminous plants and 9 % other herbs (E) and 87 % leguminous plants and 13 % other herbs (F). The fields were cut weekly during the summer in 2010, to estimate weekly biomass production.

Levande fäbodbruk på 2000-talet : -svårigheter respektive möjligheter

Mountain holding in the 21st century ? difficulties and possibilities This study examines the difficulties and possibilities that mountain holding farmers have today. The following questions were considered: i) Who is cultivating mountain holdings today? ii) Which is the most important reason to keep animals there? iii) What kind of subsidies are most common? iv) What kinds of animals and what breeds are the most common? v) For how long period of time are the animals kept at the mountain holdings every season? vi) How are the fundamental regulations in the animal welfare law being followed, and are there any problems/conflicts in keeping animals at the mountain holdings? vii) What meaning do the animals have for the farmers and what are the farmer?s thoughts about the future? A survey based on these issues was sent out to 107 mountain holdings farmers with animals on grazing land, where 59 % submitted a response. The results showed that knowledge on how to keep animals at the mountain holdings was overall good.

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.

Biologisk mångfald i små grönområden : Inventering av insekter och fåglar i bebyggda områden i Solna kommun

All over the world the urbanisation increases at the expense of green areas. Many plants and animals are endangered today because their habitats gets smaller or disappear. The green areas that are left in city centres and suburbs are often small and surrounded by roads and buildings. Despite this, several studies have shown that these small green areas may house large Biological diversity.This project aims to study the Biological diversity in small green patches in residential areas. The study has been carried out in Råsunda in Solna municipality (Stockholm county) during the period May?July 2006.Three equivalent areas (5000?10 000 m2) with quite many old oaks were chosen for the study and inventoried for birds and saproxylic insects.

Förändring av grönområden i Västerås tätort det senaste seklet : Konsekvenser av att grönområden förändras

This thesis was done after a request from the county?s administrative board of Västmanland to provide the board with a better understanding of how green areas have changed within Västerås municipality over time.The purpose and goal of this study was thus to measure and analyze how much of the green areas within Västerås municipality that have disappeared during the past one hundred years as well as to provide a review of previous studies regarding the importance of green areas for humans as well as the Biological diversity.In order to answer these questions I have in this study used a combination of a literature study, cartographic analysis as well as a time series analysis. The computer software used to do the measurements of the green areas was ArcGIS which is a geographical information system.In the cartographic and times series anlaysis measurements and analysis was made of the district map of 1911, the economic map of 1950 and the property map of 2011. The measurements show that the municipality has grown with 46,3 km2 over the last one hundred years. New neighborhoods? have emerged and the municipality has expanded.

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..
