1323 Uppsatser om Habitat patch size - Sida 6 av 89

En studie av landskapsindex för kvantifiering av rumsliga landskapsmönster

Syftet med uppsatsen är att utvärdera två landskapsindex: ett formindex som beräknar formen för varje markanvändningsyta ( eng. "patch"); ett diversitetsindex, som beskriver de olika markanvändningarnas relativa utbredning. Formindexet beräknas på två olika sätt, beroende på om dess storleksberoende inkluderas eller ej. Utvärderingen körs för ett landskap på cirka 50 km2, men även för tre mindre områden i landskapet: åkerbygd, mellanbygd samt skogs-bygd. Samtliga områden jämförs sedan i två olika skalor, flygbild respektive satellitbild..

Förskolebarns matematik

This report is a qualitative study on children aged three to five years who are in the Swedish preschool. The purpose of the study is to investigate how five experienced preschool teachers view the way children between three and five years acquire basic mathematical concepts, basic numeracy and geometry. The aim is also to find out whether teachers feel that the size of the group of children affects their learning.The study contains information about what preschool teachers think about the way children learn mathematics and how the size of the group of children affects this learning. From the results it can be seen that children learn Mathematics, both in everyday situations and when playing. Moreover, the group size does not seem to affect the mathematical learning of the child.

Kapitalstruktur : En studie av branschtillhörighets, storleks och lönsamhets inverkan på företags skuldsättningsgrad

The purpose of this essay is to study the impact of different factors on corporate capital structure. The factors studied in relation to corporate debt ratio are industry affiliation, size and profitability. The study involves all 252 companies quoted on the Stockholm stock exchange and cover a time period from 2007 to 2011. The result shows that branch affiliation has a significant impact on corporate debt ratios. Regarding size and profitability, however, these factors do not have an evident impact on corporate debt ratios..

- För vi har slutat nian, fyfan va' vi é bra! : En kritisk diskursanalys av grundskolans fostran från Lgr62 till och med Lpo94

I have studied the curriculum for the compulsory Swedish school, from the curriculum from year 1962 when the Swedish grundskolan became a reality, to the curriculum from year 1994, the one in practice today. My primary interest has been what the curriculum says about bringing up the Swedish youth. My theory has been the British analyst Norman Fairclough?s Critical Language Studies. His thoughts about actual discourse, type of discourse and order of discourse has led me through out this essay.

Optimering av OTEC-system

Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.

Kan man genom kartstudier förutse häckningsframgång för ängshök (Circus pygargus) i Uppland? :

Montagu´s harrier (Circus pygargus) is a diurnal, Eurasian raptor, which migrates from its northern breeding grounds to winter in sub-Saharan Africa. In Sweden, its core breeding area is centred on the island of Öland, with a stable breeding population of approximately 40 pairs. The province of Uppland is on the northern end the distribution range, where 4-8 pairs have regularly bred since the 1980s. In Sweden, the Montagu?s harrier is classified as an endangered (EN) species. This classification is partly due to a lack of preferred nesting habitat, such as shrub-lands or dense wetlands with Claudium spp.

Lokala skillnader i konsumtion av påväxtalger och terrestra löv hos en differentierad population av Asellus aquaticus

That ecological and evolutionary processes can take place on the same time scale is a recent insight. Today we also know that they are directly linked to each other. In the lake Tåkern, in year 2000, there was a structural change when phytoplankton declined and submerged vegetation, mainly stoneworts began to spread. This led to evolutionary changes in the aquatic sowbug, Asellus aquaticus which had previously been limited to the reed, most likely feeding on detritus. But then, sowbugs could exploit the new habitat in stoneworts and a new food resource in terms of periphyton.

Stjälkröksvamp (Tulostoma brumale) : stora eller små individer?

The spatial population structure of the saprotrophic basidiomycete Tulostoma brumale was investigated at a site in south eastern Sweden. Sporocarps were mapped and collected, and somatic incompatibility tests between mycelial cultures cultivated from the sporocarps were used to identify genets. Calculations of the size and numbers of genets and their distribution were performed. The spatial distribution of the tested sporocarps and the identified genets are presented graphically in a grid. The total number of identified genets within the investigated area (1210 m2) was 27 based on 48 tested sporocarps.

Fortplantning och fortplantningsproblem hos tikar av svensk och finsk lapphund : en jämförande studie

The Swedish Lapphund is one of our eleven Swedish domestic breeds of dogs and one of Sweden?s oldest dogbreeds. The Finnish Lapphund?s origin and physical conformation is similar to that of the Swedish Lapphund. One aim of this study was to examine whether the average litter size differs between these two closely related breeds, and if so, try to find causes for this.

Sjuksköterskans attityd till att vårda patienter med psykisk sjukdom i den somatiska vården

De psykiskt sjuka tar allt större plats inom den somatiska sjukvården men forskningsfältet är nytt och kunskapsluckor existerar. En systematisk litteraturstudie gjordes. Litteraturstudiens syfte var att belysa sjuksköterskans attityd till att vårda patienter med psykisk sjukdom i den somatiska vården.En databassökning har gjorts i fyra databaser med omvårdnadsfokus: Cinahl, Pubmed och PsycInfo. Sex studier inkluderades. Ur dessa har utkristalliserats tre återkommande teman: attityder som avspeglar sjuksköterskans erfarenheter, vårdmiljöns betydelse på sjuksköterskans attityder och utbildningens betydelse för sjuksköterskans attityder.En stor mängd negativa attityder existerar men även en del positiva, ofta knutet till sjuksköterskan personliga attityder.

Studier av habitatval och revirstrukturer hos vassångare (Locustella luscinioides) i Tåkern

The Savi?s Warbler (Locustella luscinioides) is a recently established bird species in a few reedy shallow lakes of southern Sweden and has only been found nesting for the last twenty years. Little is known about the species' habitat preferences, breeding biology and demands for specific territory structures at breeding sites in Sweden. Knowledge of a newly established species? habitat requirements is essential to maintain a viable population and design action plans.

Ideella organisationer- En arena för diktatur

The purpose of this research was to examine the current field of management in non-profit organizations, mainly focusing on managerial approaches, but also the impact of organizational size on the shaping of governance. Non-profits are widely discussed in contemporary research, particularly due to the increasing external pressure on voluntary organization to professionalize the way they work in line with standards in the private sector. Due to this our thesis aims to investigate whether professional, bureaucratic approaches are useful when governing a non-profit organization, or if social structures are enough to ensure goal congruence and efficiency. To conduct this research qualitative interviews were carried out and a case- study was made, using the Swedish Karate Federation as object of study. Results show that formal and more professional structures are useable to achieve efficiency and prevent inertia within the organization.

Det ansiktslösa ägandet, en pådrivare av utdelningar?: En studie i hur det institutionella ägandet påverkar svenska börsbolags aktieutdelningar

This paper investigates the relationship between dividends and institutional and foreign ownership in Swedish firms. We use a dataset which covers the Swedish stock market over the period 1999-2009. The institutional ownership is defined as mutual funds, pension funds and insurance companies and these are analysed separately. The study confirms the expected positive relationship between the level of institutional investors in a firm and the size of dividends. We also confirm? the expected negative relationship between foreign investors and the size of dividends paid by Swedish firms.

Informationsmaterial för nya hyresgäster

Jag har arbetat med att producera ett informationsmaterial för nya hyresgäster hos hyresvärden Ydewalls i Katrineholm. Jag har använt mina kunskaper inom informationsdesign, textdesign och grafisk form för att utforma materialet.    Syftet med informationsmaterialet är att ge de nya hyresgästerna den information som de kan tänkas behöva under tiden de bor i lägenheten. Ydewalls vill genom att förbättra sitt material minska antalet onödiga förfrågningar från hyresgästerna.   Jag har arbetat efter min huvudfråga: hur skapas ett informationsmaterial utifrån de principer som finns inom informationsdesign? För att få svar på min fråga använde jag mig av metoder som litteraturstudier, komparation, deskription, enkätundersökning samt utprovningar.
