Dagsljusets gestaltande förmåga : en studie av dagsljuset och dess samverkan med vegetation i inglasade miljöer

Det här examensarbetet har som syfte att undersöka dagsljusets gestaltande förmåga i inglasade miljöer. Hur det är möjligt att använda dagsljuset i samverkan med växtlighet samt färg, form och textur hos miljöns fysiska element för att påverka den rumsliga upplevelsen. Ljus i ett rum är påtagligt närvarande, något som inte går att ta på men på samma gång kan dess strålar ibland uppfattas närmast som materia. Ljuset är variationsrikt och en avgörande förutsättning för visuell gestaltning. I det här arbetet har jag fått använda mig av synsinnet som ett mätinstrument genom att visuellt utvärdera upplevelsen och hur dagsljuset beter sig i några inglasade miljöer. I kombination med min personliga upplevelse av platsen har även kvantitativa mätningar av ljusets styrka gjorts.

Viltanpassad röjning längs skogsbilvägar som en foderskapande åtgärd för älgen

The moose is a keystone species in the boreal forest ecosystem, but the dense Swedish population do cause some serious problems. From a forestry perspective, their browsing on young Scot pine (Pinus sylvestris) causes extensive losses of revenue. Adjusting the cleaning along roadsides of low trafficked forest roads can favour the production of plant species preferred by the moose. This is thought to redirect the moose´s browsing to the roadsides and thereby decrease the damages on commercial forest.The aim of this study has been to present a first evaluation of the vegetation in roadsides, one year after wildlife-adapted roadside clearing has been undertaken. In the wildlifeadapted clearing operation, the roadside was widened by removal of some trees in the forest edge whereupon a complementary clearing with a conventional chain flail was conducted.

Förändringsstrategier vid övergången till ett kontantlöst banksystem

Title:Change strategies in the transition towards a cashless banking systemLevel:Final assignment for Bachelor Degree in Business AdministrationAuthor:Elin Lånström och Vildana SmailagicSupervisor:Stig SörlingDate:August 2013Aim:In our study, we compare what it is that drives a bank to implement changes in their business, what problems these changes may bring, and how organizations deal with these. We do this by studying how different banks choose to relate to the handling of cash.The questions we ask ourselves are:? What lies behind the decision to make changes in cash management?? How is the change implemented in practice?? What do banks think this change will mean for the future?Method:The study was conducted with the help of a qualitative scientific method. We conducted interviews with representatives of four banks, and made use of secondary data in the form of scientific literature and scientific articles.Result & Conclusions:Organizations implement changes in order to adapt and achieve balance with their environment but also within the organization itself. Our study shows that the decision to introduce cashless branches is mainly a result of banks' efforts to become more cost efficient.

Modellering av reflektans från ett sockerbetsbestånd med hjälp av en strålningsmodell

The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.

Växter för miljöer där barn leker : en analys med utgångspunkt från Halmstad kommun

Det har gjorts flertalet studier som bekräftat vegetationens betydelse i leksammanhang, men det finns ett behov av vidare studier i enskilda växtval. Denna studie har gjort ett första försök i att bedöma vedartade växters lämplighet för leksammanhang utifrån (A) risk, (B) slittålighet och (C) lek. Studien har gjorts utifrån vegetation i direkt anslutning till ett antal lekplatser i Halmstad kommun. Lekplatsen som ståndort ställer stora krav på växters tålighet för slitage, och det är därför ett viktigt kriterium i arbetet med att välja lämpliga växter. Risker som bör undvikas i leksammanhang är taggar, tornar och giftiga växtdelar. För bedömning av växters positiva påverkan i leksammanhang studerades växtmaterialet utifrån kriterierna: (1) förekomsten av löst material, (2) barns möjligheter att på olika sätt påverka och använda vegetationen och (3) växters potential till kojverksamhet. Studien visar att samtliga studerade växter kunde bedömas som slittåliga och att alla växter uppfyllde lekkriteriet löst material.

Faktorer som påverkar växters utveckling : en studie av vegetationens utveckling i rondeller

Cirkulationsplatser är vanligt förekommande i vårt samhälle och det byggs ständigt nya eftersom det är säkrare och smidigare än en fyrvägskorsning. Rondellen är ofta en plats för utsmyckning i form av växter eller av konstverk. För att växter ska ha ett prydande värde i rondeller måste de utvecklas bra och det här examensarbetet undersöker just hur växter har utvecklats i rondeller sedan plantering. Arbetet grundar sig i en inventering av 74 rondeller fördelade i regionerna Norrland, Mälardalen och Västkusten som har olika klimatförhållanden och har olika stor användning av vägsalt vintertid. Det insamlade inventeringsmaterialet har sorterats, analyserats på artnivå och på generell nivå med utgångspunkt i en litteraturstudie om växters utveckling. Litteraturstudien har även legat till grund för ett inventeringsprotokoll baserat på symptom som växterna kan visa upp beroende på bland annat vatten- och näringstillgång och växternas härdighet. Under arbetet har jag kommit fram till att man som planerare, projektör, anläggare och förvaltare har stor påverkan på växternas utveckling i rondeller.

Ungdomars erfarenhet av livsstilsförändring

It is reported that adolescents' health is deteriorating, when their mental illness has increased. Adolescents' social conditions have also become worse. The mental illness is linked to the individual living conditions. The purpose of this study is to investigate which factors adolescents experience have been contributing to making a lifestyle change. The apparent factors can be used to promote adolescents´ health.

Regionkontor i Bryssel, En studie om regionala mål, medel och samarbeten i den europeiska sfären

The base for the study is laid during an internship at a regional office in Brussels. The study initially concentrates on the function and activities of different regional offices located in Brussels, in order to answer the core question.The main focus is to reveal an eventual change of cooperation patterns between different regional offices, and in particular the eventual redirection away from a main cooperation between offices deriving from the same national state.Through an empirical material, based on a series of interviews, an analysis is made using three hypotheses concerning the patterns of cooperation among regional offices.The notion of a coming change stated by, in particular, two older studies is used as a theoretical steppingstone with the conclusion that a change, in the way offices collaborate, has taken place..

Beredelsens plats i Svenska kyrkans mässordning

The Church of Sweden sent during the spring 2010 two documents, Teologiskagrundprinciper för arbetet I 2006 års handboksgrupp and Mässans grundordning forconsideration. The documents are parts in the work with writing a new service-book for theChurch of Sweden. After the documents had been sent for consideration by the dioceses therehas been a discussion about the proposal to make the preparation in the service of HolyCommunion facultative. My main question has been to se if there will be any change of theconfession, faith and doctrine in the Church of Sweden if the preparation becomes facultative.I have seen that the service-book is an expression for the confession of the Church of Sweden,therefore there will be no change of the confession of the Church of Sweden, but a change ofits expression.I have seen that there is no consensus in how the dioceses react over what is written in thetwo documents about the forgiveness and the atonement. My conclusion is that it may bydifficult for the Church of Sweden to fix a new service-book without first fix what the Churchof Sweden means with forgiveness and atonement..

Övergången från SAB till Dewey i forskningsbibliotekssverige: En organisationsförändring ur de anställdas perspektiv

In November 2008 the National Library of Sweden decidedto switch classification system from SAB to Dewey decimalclassification. SAB had then been the main classificationsystem in the whole of the Swedish library field for 87 years.Included into the decision was not just the nationalbibliography but also the research libraries of Sweden. Thisdecision was in alignment with a West European tendency tochange in favor of the internationally well-spreadclassification system Dewey in order to co-operate more inthe cataloguing process. The purpose of this study takenplace in the autumn and winter of 2013 is to examine howlibrarians involved in the transition feel about what differentways the implementation has affected the research libraryorganizations. We also aim to study the librarians? view onthe involvement of the research libraries into the decision ofthe changeover.

Stadsklimat/Gatuklimat :

The purpose of this paper is to understand the climate of the street and how it can be modified to better meet the needs of the street and the user groups. At the same time the conditions of the street and its surroundings also has to be taken into account. To accomplish this it is necessary to have a broad knowledge of the climate conditions in the city. Therefore an overview of the climate elements and how these are modified in the built-up areas are given. The part of the paper which deals with the city climate has a global approach to be able to give an as complete picture as possible.

Verksamhetsförändring : Sociologiska perspektiv på implementeringen av barnkonventionen inom BVC

This study aims to create an understanding of how employees relate to directives that come from a level above them in the hierarchy and is to be implemented in their working activities. This is studied by examining a case where a work group has tried to implement orders, given to them by the government and through a work group in the level above them in the organizations, concerning how employees working with child health care is to educate parents regarding the child convention. The method that have been use in this study is group interviews with 19 child health care nurses and the two main questions that are asked is why has it been difficult to implement the orders and how have the child health care nurses expressed their resistance to the changes, this since only five of the nurses had begun working with the child convention. The theories that have been used focus on how resistance towards change is expressed, organizational incapability and reluctance towards change, as well as how grass root bureaucrats relates to change. The conclusion that can be drawn from this study is that it is important to let the concerned parties participate from the beginning of the process, to minimize their reluctance to the changing process.

Användning av geografiskt informationssystem (GIS) vid studier av nötkreatur i landskapet - en pilotstudie :

The Animal Protection Agency was in 2006, commissioned by the Government to: Evaluate how free range animals in the winter, can be kept and managed with special emphasis to animal welfare. The Animal Protection Agency was closed later in 2006 and the commission moved to the Swedish Board of Agriculture. The keeping of free range out wintered cattle, certain basic requirement are needed: by regulation, cattle should have access to a lying hall or other building that gives protection against aversive weather and wind and should offer a dry and clean lying area. There is a possibility for farmers that get an exemption from this regulation. But cases regarding farms which have had difficulties for this exemption has led to a discussion about if the animals can get the same protection in the nature which is comparable to a lying- hall.

Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd

The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth. Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.

Vildkaniner som naturvårdare? : En studie om hur kaniner påverkar pH, mängden öppen sand och vegetation på en sandstäpp i sydöstra Skåne.

Sandstäpp, eller ?xeric sand calcareous grasslands?, är en starkt hotad naturtyp i Sverige. Sandstäpp hyser många unika och sällsynta växter som kräver bland annat högt pH-värde och uppbrutet vegetationstäcke. De största hoten mot sandstäppen är försurning och igenväxning. I denna studie undersöktes om vildkaniner (Oryctolagus cuniculus) kan motverka dessa hot genom att gräva upp kalkrik sand och därmed gynna sandstäppens unika vegetation.
