Brandrelaterade insekters lokala artrikedom i förhållande till olika miljövariabler : Fokus på betydelsen av konnektivitet på brandfält i boreal skog i Västerbottens län

The last century, forest fires have decreased in frequency due to efficient fire-suppression along with the growth of the industrial forestry. Since 1990, fire has been reintroduced under controlled forms to recreate burnt habitats. Many species that are dependent on, or benefits from, forest fires have increased since fire was reintroduced. The importance of connectivity is often addressed in Ecological research. This is particularly important for species dependent on short-lived habitats such as burnt forests.

Självskattning av exekutiva funktioner vid kognitiv träning : En utvärdering av The behavior rating inventory of executive functioning - self report

Traditionellt utvärderas effekter av kognitiv träning med objektiva prestationsmått. Syftet med uppsatsen var att undersöka självskattad exekutiv funktion som ett alternativt mått för att utvärdera effekter av kognitiv träning. Som utfallsmått valdes The behavior rating inventory of executive functioning - self report (BRIEF-SR). Vidare användes blandad design med för- och eftermätning samt tre oberoende grupper. Gymnasieelever (n = 63) delades in i; aktiv träningsgrupp, aktiv placebogrupp och passiv kontrollgrupp.

Alternativ till fiskbaserat foder till karnivora fiskar

If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.

Prim, Stadsförnyelse i Barcelona

This final project discusses renewal and upgrading of the area of Prim. It is discussed how this industrial area can be an attractive neighborhood with a varied range of services and commercial trade. Prim is located 2km north-east of the center of Barcelona. The area boarders to a deep railway valley that historically has separated Prim from its neighboring districts. At present there is almost no housing, services or commercial trade within the area and the industry is discontinued or the existing industrial buildings are derelict. There is also a lack of green recreational areas.

Förtätning ur ett socialt perspektiv

Urban densification as a planning strategy is of interest in the planning context of today. It is also seen as a part of the sustainable development. Urban densification as a concept is commonly used in the discussion of a sustainable development. Thus, the question about urban densification is an important challenge in the current planning context. A deeper understanding of the process which urban densification has developed from is necessary, since planners then will be more able to manage this challenge.

Vegetationsutveckling och brandhistorik i Tyresta under 9000 år : en pollenanalytisk studie av en skvattramtallmyr i Tyresta nationalpark, Södermanland

Analyses of pollen and charcoal in peat cores, together with age-structure data of Pinus sylvestris from a Ledum-Pinus-mire in the Tyresta National Park (south-east Sweden) show the regional vegetation succession and fire history over the last 9000 years. Five major stages of mire development are identified: 1. Lake (c 7000-6400 cal BC); 2. Wet fen (c 6400-6000 cal BC); 3. Deciduous fen (c 6000 cal BC to c cal AD 700); 4.

Antinutritionella substanser iåkerböna, ärter och blålupin vidutfodring till mjölkkor

There is a shortage of locally produced high quality protein concentrates in Europe andSweden. Local production would decrease the dependency on imported soybean and meet thedemand for organically grown feedstuff from Ecological dairy farmers. Field bean (Viciafaba), peas (Pisum sativum) and sweet lupin (Lupinus angustifolius) are good alternatives tosoybean, but contain anti-nutritional substances (ANS) that could reduce their use as proteinconcentrates in dairy cow diets. The aim of this literature study was to review which ANSfield bean, peas and sweet lupin contain and whether they affect dairy cows negatively.Trypsin inhibitors and Chymotrypsin inhibitors (TI) were present in all three crops. TI couldbecome inactivated and degraded in the rumen, but due to the high passage speed of thedigesta, most TI left the rumen in an active state.

"A gentle push": barnets inskolning i förskolan

An absolute majority of all Swedish children begins to attend preschool at some point between the age of one and five. The acclimatisation to preschool means a great change in every small child's life. They leave all that is well known, the parent and their home, to face a whole new environment with new kids and adults to get to know and learn to trust.The purpose of this study has been to find out how the professionals in preschool reflect upon the child's acclimatisation at preschool. More specifically we wanted answers to how the preschool teachers, in their work with the child's acclimatisation, relates to the today, in preschool, much debated relationship between the two perspectives care and pedagogy.This qualitative study is based on ten interviews with preschool teachers at different preschools in a small town in Sweden. The analysis is based on a presentation of the interview material compared with earlier research and the theoretical aspects we have chosen, which are Bronfenbrenners Ecological Systems Theory and the Object Relations Theory.While working with this paper it has come clear to us that there is no explicit or common definition of the concept of care within preschool, while there is a clear definition of the concept of pedagogy.

Vems landskap ska förändras för att öka den biologiska mångfalden? : En studie av skillnaderna i odlingslandskapets konnektivitet med avseende på två skyddsvärda arter med olika preferenser

Organisms relevant for nature conservation dont follow administrative borders. Because of this there is a need for a landscape perspective within conservation and planning, and a need for the species of interest to have legal protection. Network analysis adapted for Ecological purposes has grown to become a powerful tool for studying and communicating the relationships between species dispersion and access to habitat. In this study the following question is posed: How is the Osmoderma eremita and the Pernis apivorus dispersal possibilities in the small scale cultivated landscape of Borås affected by exploitation in respect to a) dispersal ability, b) habitat quality, c) position of habitat patches in a network? The analysis were based on municipal and regional nature conservation data, which in due to confidentiality is not accounted for in the report by maps, coordinates, etc.

Social hållbarhet och attraktionsfaktorer i en urban kontext. Fallstudie över Malmös nya stadsdel Hyllie

Do new, attractive neighborhoods meet the requirements of being socially sustainable? This essay is based on the potential conflicts between the pursuit of social sustainability, while the theory of the creative class influence city planning. Social sustainability is difficult to measure, but implies broadly that everyone should have equal rights and opportunities. A city or region that aims to attract a certain type of people by providing what they ask for, might pay less attention and spend less resources on the rest of the population. Socially sustainable - for whom? The new district Hyllie in southern Malmö stands in focus, and the paper seeks to identify how different operators in Malmö defines the concept of social sustainability, how it is implemented in the design of Hyllie, and if any potential conflicts may arise.Interviews with the following informants; representants from the Office for City Planning in Malmö, the nonprofit organization Sustainable Development Skåne, the Commission for a Socially Sustainable Malmö and the company Skanska Öresund have constituted the main methodology, among with reading and analyzing existing documents and policies relating to the development of Hyllie.

Hållbar utveckling i svensk planeringspraktik : en diskussion kring förtätning och andra ambitioner

Examining the social component of sustainable forest management in Prince Albert and Vilhelmina Model Forests

Due to the forest industry downsizing, many communities in rural forest regions in Canada and Sweden are facing problems to survive. In order to create community sustainability, resilience and well-being in remote forest regions, the view on the forest resources has shifted towards multiple use, through the concept of sustainable forest management (SFM). Beside the economic and Ecological elements of sustainability, the social forest values are needed, contributing to the human well-being, local participation, stakeholder collaboration, human rights and cultural connection. In this thesis the embodiment of the social component of SFM within Prince Albert Model Forest (Canada), and Vilhelmina Model Forest (Sweden) will be examined. Being partners and facing similar challenges as rural boreal forest regions, the two model forests are compared through analysis of projects and activities, conducted interviews and organization documents. Looking at projects mentioned as successful by the interviewees, they all have elements from the social values of SFM. The direction can be explained by the introduction of the Forest Communities Program in Canada, demanding the Model Forests to work towards community stability and resilience, the Model Forest organization concept itself and the way global focus are increasing around social forest values. In the future, it may be important that the role of the MFs enable some kind of political authorization and legitimacy in order to improve conflict solving and indigenous rights equality.

Ett blink i bruset: En uppsats om möjligheten att påverka konsumenten vid livsmedelsinköp

Today endless choices exist for a customer in the grocery store in terms of information, products, brands and prices. Consequently, it is important for retailers and brand owners to gain insights in how they can manage to break through the clutter to reach the customer. Displays that include some kind of motion element are assumed to possess an attention grabbing ability, which is a necessary first step in influencing the customer?s decision making. Therefore we have explored whether so called dynamic displays are efficient in grabbing attention and influencing customer behaviour.

Är grön det nya svart? - En studie om hur miljövänliga kläder skapar konkurrensfördelar

Bakgrund och problem: Under de senaste 20 åren har en global oro växt kring konsumtionens påverkan på miljön. Faktorer som den globala uppvärmningen, hål i ozonlagret samt katastrofer som Tjernobyl var några av drivkrafterna. Historiskt börjar nu den gröna marknadsföringen att framträda på marknaden. Den delades in i tre faser varav en fas representerar marknadsföring av miljövänliga produkter, designade för att främja en hållbar konsumtion (Mishra & Sharmra, 2012). Det är dock under 2000-talet som konsumenternas miljömedvetenhet leder till en ekologisk trend och livsstil.

Tigern, igelkotten och biskopen : Svenska kyrkans bemötande av Andra världskriget och beredskapen genom Torsten Ysander

Studien innefattar en jämförelse av beteende och attityder till miljöfrågor mellan studenter från Jönköping, en individualistisk kultur, och Quito, en kollektivistisk kultur. Syftet är att undersöka om studenternas kulturella och sociodemografiska bakgrund återspeglar skillnader i attityd och beteende till miljöfrågor. Studien använder sig av en enkätundersökning som är baserad på tidigare forskning, det ekologiska fotavtrycket och mätinstrumentet New Ecological Paradigm skalan. Resultatet diskuteras utifrån tidigare forskning inom området med utgångspunkt från teorier om individualistisk och kollektivistisk kultur och Theory of Planned Behavior.Studien visar att det finns signifikanta skillnader i studenternas angivna miljövänliga beteende inom ett flertal områden, exempelvis studenternas angivna resvanor och hur mycket de återvinner. Resultatet tyder på att det finns förklaringar till skillnaderna i de sociodemografiska faktorerna.
