Sociala nätverkets betydelse för vägen ur hemlöshet : En narrativ studie

The aim of this study was to use stories from three people who previously lived in homelessness to increase the knowledge of the social network's impact on the process of exiting homelessness. In order to answer our questions, whether the social network facilitated or hindered the way out of homelessness, we have used a narrative method to take advantage of these person's life stories. As a theoretical perspective, we used the ecology of human development, based on the idea that human development occurs in interaction with their environment at different levels. Results showed those interviewees' networks had a significant impact on their path out of homelessness and that these relationships both facilitated and hindered this process. At the same time, these relationships affected our interviewees in different ways and were found in various areas of life, which indicates that there is more than one way out of homelessness.

Sol, jord och vatten. : Barns tankar om den ekologiska processen

Studies show that the interest and knowledge about science among teenagers is decreasing. They also reveal the difficulties to explain the ecological processes and that the ideas about the nature are collected from everyday life and early school years.The intention of this investigation was to find out more about children?s ideas and knowledge about the ecological processes and to compare these results with the curriculum.The method was a questionnaire and interviews with children in school year 1 ? 6. The aim of the studies was also to find out if any progress connected to age could be found, concerning understanding of the ecological processes.The results showed difficulties in achieving the predestined goals for biology and chemistry concerning ecology cycles and they differed a lot between the children. Often the learning process showed very little progress.

Bron och Attityderna : en undersökning av politiska åsikter kring Öresundsbron

This thesis deals with past and present political attitudes towards the Öresund bridge. It describes the decision making process which preceded the construction of the bridge, and has a short historical introduction to it. It then presents the attitudes towards the bridge of five different political parties, all represented by regional politicians. This empirical information was obtained through interviews with politicians and literature studies. The author then analyzes the empirical information with the help of the human ecological triangle developed by Steiner, and the center-periphery theories of Wallerstein and Persson.To conclude, the author describes what the central problem is in the case of the Öresund bridge from a human ecological perspective and analyzes the empirical data collected..

Biodling i Stockholms stadskärna : Ekonomi, ekologi eller ekosofi?

Previous research confirms that there is a major decline of pollinators worldwide. Investigations have mainly focused on pollination services in the agricultural landscapes and therefore, there is a lack of knowledge on the effects pollinators may have in urban environment. This paper examines the presence of honey bees in central parts of Stockholm, Sweden. The study presents what conditions, possibilities and motives there are behind the phenomenon of urban bee keeping. I found ten locations with beehives and a total of 18 hives within the delimited area. Nothing seems to indicate that conditions may limit the presence of honey bees.

Samspelet mellan ekologi, produktionsförhållande, politik och sociokulturella faktorer gällande Östersjöns torskbestånd från 1970-talet till 2003

The study begins with a historical background over the fisheries development in North America and in the Baltic Sea area in Finland and Sweden. As we can see the fisheries development depends on the interaction between ecology, state of production, politic and also social factors. In Sweden the fishery politic has changed over the period of the study. In the 1970: s the main politic focus was on the fisheries progress, expansion and rationalization. The State in Sweden took a vast part in this development and gave economic support.

Hållbar tillväxt - möjlighet eller motsägelse? : En granskning av EU:s Lissabonstrategi ur ett humanekologiskt perspektiv

The purpose of this study is to make a close and critical scrutiny of the EU Lisbon Strategy and the assumption of `sustainable growth´. A basic question is to clarify what is meant by `sustainability´ in the economic and the environmental dimension respectively, and also, to analyse the meaning of `sustainable growth´. Secondly, I try to investigate the relationship between the economical and environmental dimensions of the strategy. Are the goals of the dimensions compatible and mutually supporting or are they conflicting? By illuminating these issues the study moves towards a final set of questions: What are the arguments that encourage or counteract the Lisbon assumption of `sustainable growth´? Is the European Union approaching `sustainable growth´ looking at different economical and ecological indicators? What are the prospects for the Lisbon Strategy as a way towards global `sustainable development´?.

The Swedish liming operation : a study about liming officers opinions about some aspects regarding ecology, economy and organization

This is a study about the Swedish liming operation and the Swedish liming officer?s opinions of some aspects regarding ecology, economy and organization. The study objectives was motivated due to the recent changes in manuals for the assessment of limed waters and the suggested changes in decision making and decreased budget for liming. Moreover the anthropogenic acidification effects on the ecology are in many ways complex. Furthermore it was made in order to gain knowledge about the liming officer?s opinions in order to improve the ability to meet their needs regarding the assessment tools and also to investigate if other things can be improved concerning the liming operation.

Ekologi som kommersiell vara

Organic cotton has been in the medias field of vision for quite some time. This interestalso reflects in a growing awareness in the textile industry where more and morecompanies today offer organic cotton in their product range. With this in mind wequestion whether organic cotton has become a viable commercial product. We alsoacknowledge there is a lacking of understanding the complex problems that organiccotton manufacture involves, for example the huge effort and cost required for a transitionfrom conventional to organic cotton farming.The purpose of this paper was to study how textile, ecology and competition today arebeing combined by companies. We wanted with our investigation to find out whethercompanies in the textile industry use ecology as a competitive advantage.

Utredningar av socialt utsatta barn : en genomlysning av risk- och skyddsfaktorer

The aim of this study is to, from a child?s family relations, describe the usage of terms relating to factors of risk and safety in science and in investigations concerning children in need of protection. It is also of importance in what way the terms are used when the Social Services suggest that measures should be taken, and in which way the children have been heard in the investigations.The issues raised in this study are: (a) How is the current life situation and life quality of the children discussed? (b) The value of factors concerning risks and protection. (c) How is the children?s own descriptions taken in to consideration? (d) Is gender issues considered? (e) How is Lagerberg?s model (Lagerberg, 1998) useful in investigations?The method of analysis is mainly qualitative however it is combined with analysis of literature relevant to the study.

Vegetationsförändringar i Hornborgasjöns naturreservat : med fokus på restaureringems följder

Den här studien undersöker hur vegetationen förändras mellan 1979 och 2010 i området som idag är Hornborgasjöns naturreservat. Sjösänkningar i området ledde till att ett igenväxt träskområde ersatte en viktig vattenreservoar och närsaltfälla. Restaureringsarbetet under 80-talet var banbrytande och antagligen ett av vår tids mest omfattande naturvårdsarbete. Studien svarar också på om restaureringen uppnådde sitt mål och om resultatet blev som man tänkt sig.I arbetet skapades en aktuell vegetationskarta för 2010, denna jämfördes med en i arbetet digitaliserad vegetationskarta från 1979. Kartbilder skapades och justerades i ArcGIS och vegetationsytornas area framtogs för att möjliggöra en vegetationsanalys mellan kartorna.

Odefinierade platser i staden : med studie i Söderälje

The purpose of this master thesis is to attract attention to the undefined spaces of our urban landscape and emphasize the need of these spaces in the city. The different values of these spaces are here clearly presented so that they can be considered when real estate developers show a particular interest in any one of these undefined spaces. The term undefinied spaces can mean a lot of things. The spaces that I now choose to define as undefined spaces are neither planned nor designed. It could for instance be a piece of leftover land in between two residential areas, or as times change, a formerly planned area might be forgotten and left to its own.

Mätning av ekosystemtjänster i jordbrukslandskapet :

Abstract In order to make the modern agriculture less dependent on non-renewable external inputs, it has to rely more on ecosystem services. The agricultural system produce not only food, fiber and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of nutrients, influencing local microclimate, pollination, biological control and detoxification of noxious chemicals. This study is an attempt to get a better understanding about the interaction among different ecosystem services and different habitats capacity to generate them. An evaluation of eight different methods is done. The ecosystem services studied are the ability to absorb solar energy, biomass production, botanical diversity, decomposition and natural predation of aphids.

Att hjälpa alla elever nå målen : En holistisk och kontextuell specialpedagogisk studie om lärarnas önskemål och behov

There is a discrepancy between national school guidelines towards inclusive education, and the current political trend towards economic efficacy, that may be problematic for teachers. The aim of this contextual study is to formulate a contextual understanding of the participating teachers? perceptions of their effort to help all their students achieve the goals set forth by school curricula, and use this understanding for the purpose of suggesting points of entry for special needs educators´ guidance of teachers? practices towards more inclusive education.Information was gathered by sending an extensive web questionnaire to all teachers within a given headmaster´s administration, sending web questionnaires to a majority of third grade students taught by those teachers, conducting interviews with a few of the participating teachers as well as with the special needs educators, carrying out a classroom observation, and gathering additional information concerning working conditions and social interactions.The data gathered in this case study has been subjected to an analytical process comprising of an assessment of the degree of inclusive approach, using the Inclusive Approach through Participation as well as the Framework of Participation, technical triangulation of all data post the inclusive assessment, and analysis of context by the Ecology of Human Development/the Bioecological Theory.The analytical process has resulted in a contextual description that has enabled me to suggest possible points of entry to be used in special needs educators? guidance of teachers? practices towards inclusive education. The degree to which there exists a collegial sense of security, varied forms of teacher-student interactions, collegial cooperation, pedagogical discussions, a dialogue in search of mutual understanding, and consequent follow-ups appears, in the light of the limited selection of participants, as relevant to these teachers ability to help their students.Further research is needed to identify valid points of entry for special needs educators? guidance of teachers? practices towards inclusive education.

Underlag för en pedagogisk turled i permakulturekobyn Suderbyn

Permaculture is a design system that aims at developing sustainable human settlements and self-maintained agriculture; it may also be used for community planning. The design system of permaculture aims at mimicking a natural ecosystem; this gives the advantage to make use of all the connections and mechanisms that exist in such a system.The purpose of this bachelor thesis was to compile and spread scientific information regarding five different themes within the areas of ecology, environmental science and permaculture. This was achieved through cooperation with the permaculture inspired Ecovillage Suberbyn in southern Gotland. Information about the central parts of a permaculture ecovillage was used as material for a series of signposts that will be located around the ecovillage Suderbyn. The five selected themes were: An overview of permaculture, The forest garden, The pond, Composting and The use of human excrement and urine..
