Landskapsplanering ur ett hållbarhetsperspektiv :
Environmental problems are accelerating with energy consumption and the release of greenhouse gases as the major issues. This affects landscape planning mostly through environmentally hazardous transportation and heating of buildings. In environmental work, the term "Sustainable development" is often used. This term was coined in the Bruntland report in 1987. A number of frameworks have been developed to clarify the term and to remind the user about relevant aspects of sustainability.
Kränkande beteende på arbetsplatsen : Hur definierar vi kränkande beteende och vad är avgörande för vår definition
Earlier research has shown the difficulty of defining insulting behaviour in the workplace. It has been noted that the individual and subjective definition is connected to the specific situation in which the potentially insulting incidence occurred. In this study we designed a quantitative questionnaire in order to hopefully elucidate the comprehension of insulting behaviour and furthermore enable a more in-depth investigation on how important the contextual meaning is. This study examined 140 (n=140) working adult?s attitudes towards insulting behaviour in the workplace and the importance of the contextual variables.
Testosteron och matematik;Fingerlängd (2D:4D) : en indikator för matematisk förmåga?
En individs prenatala testosteronhalter kan mätas genom att ta fram ett relationstal mellan längden på pek- och ringfinger: ett 2D:4D digit ratio index. Studier har visat att det finns ett samband mellan högre testosteronhalter och god matematisk förmåga. I föreliggande studie deltog 40 svenska gymnasieungdomar. Två hypoteser undersöktes: det finns ett samband mellan 2D:4D och matematikresultat samt det finns ett samband mellan kön, 2D:4D och matematikresultat. Datainsamlingen bestod av fingermätningar och provresultat i matematik.
Välfärdseffekten av en konkurrensutsatt tågmarknad
The aim of this paper is to describe how to measure welfare effect of the deregulation and increased competition of the public transport by railway in Sweden. The paper also includes a numerical example of how to measure the welfare effect. In our study we use public data from SJ regaring quantity and ticket prices for the period 1996 - 2005. We have used equivalent variation, EV, as the method to measure the welfare effect. We demonstrate how to derive the equation to calculate EV by starting with a Marschallian demand function.
Green feed in the marine fish farming : how to communicate water benchmarks to stakeholders
Global catch fishery is said to been oppressed to its limit (Boyd & Schmittou, 1999), further implying aquaculture might be the only solution to the world demand for fishery products. The applied term aquaculture in this paper refers to the one used by NOAA (2008); breeding, rearing, and harvesting of plants and animals in all kind of water environments, including but not limited to ponds, rivers, lakes, and the ocean. According to Shamshak & Anderson (2008, p. 74) aquaculture has over the past 20 years been the fastest growing food sector with an average annual growth rate of 8.7%. It further represents approximately 37 % (Shamshak & Anderson, 2008, p.
Väneramplitud ? Lönsamhet? : Kvalitativ studie av åtgärder, genomförda för att reducera risker och kostnadspåföljder av en förändrad vattenregim
Tappningsstrategin för Vänern ändrades i ett beslut från Länsstyrelsen i Västra Götalands län och Vattenfall AB, på uppdrag av regeringen år 2008. Detta gjordes för att minska risken för översvämningar i Vänern. Åtgärden var föreslagen av Klimat- och sårbarhetsutredningen, som försökt utreda konsekvenser av klimatförändringar för Vänern i ett framtida förändrat klimat. I utredningen används en metod för att mäta kostnader. Metoden är en kostnads-nytto-analys (Cost-Benefit-Analysis; CBA) som användes för att utvärdera bland annat Vänern med omnejd. Enligt denna uppsats saknas det värdering för naturmiljö och sociala faktorer i denna utredning.
Den nödvändiga kreativiteten? : Om den eventuella nödvändigheten av ett gymnasiegemensamt forum för kreativitet, kulturell bildning och eget skapande för att nå samtliga av läroplanens mål.
The swedish education system in general and the swedish gymnasium in particular is at the point of a thorough reform of the guidelines in education. One major difference given in the guidelines is that the former core subject of arts education is abandoned in favour of making history a mandatory class. This despite the curriculum outlined in 1994 remains. Through comparativ text analysis of the documents and reports outlining this reform and defining the curriculum as well as the guidelines for the education system this study aims to point out the reasons for this change. Through in depth interviews with teachers, educators and authorities in addition to readings of contemporary research on arts in education the study will depict a larger picture of the scheme of things.
Beslutsprocessen vid köp av bostadsrätt : En jämförelse mellan generation X och generation Y
Fondsparandet har länge varit den dominerande sparformen i Sverige. Totalt ägnar sig hela 74 procent av Sveriges befolkning åt aktivt fondsparande, och andelen blir högre vid pensionssparande. Tendensen är tydlig, svenskar ägnar sig allt mindre åt att själva äga aktier och har i stället överlåtit sparandet till banker och fondförvaltare. Storleken på en aktiefond har stor betydelse för vilken strategi en förvaltare väljer. Tidigare studier har funnit att det finns skillnader mellan förvaltad fondförmögenhet, avkastning och risktagande.
Upplevd livskvalitet hos personer med MS
Many persons with long-term illness experience a decline in their quality of life. Perceived Quality of Life is a subjective term based on prior personal experiences and is highly individual. The aim of this qualitative study was to investigate perceived Quality of Life in persons with Multiple Sclerosis and to get knowledge if physical therapy changes a person?s quality of life. Three women and three men with a range of disability were interviewed in depth.
Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Produktutveckling av koncept för isbanesystem
Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.
?R KUSTN?RA ALK?RR I BOHUSL?N ETT ?BLUE CARBON? HABITAT?
In coastal wetlands carbon/organic matter can be stored for long periods of time thanks to, among other things, the presence of water which slows down the decomposition. Because of this, restauration and management of such habitats have the potential to decrease the emission of greenhouse gasses and help mitigate climate. Internationally these environments are called ?blue carbon? ecosystems. In Sweden, alder (Alnus glutinosa and Alnus incanata) covered wetlands along the coast is a nature type that potentially could function as a ?blue carbon? habitat.
Färden till hållbarhet : en studie kring påverkan och ansvarstagande för en hållbar turismutveckling i utvecklingsländerna
The purpose of this dissertation is to describe and analyse the effects of tourism in developing countries and the attitudes and working methods of Swedish tour operators towards sustainable tourism. We have chosen to use a qualitative research according to a hermeneutical view. We have carried through in-depth interviews with eight tour operators. The theories have been divided into the effects of tourism and sustainable tourism goals which have social, economic and environmental starting points. The empiricism describes the work and activities of the tour operators and compiles the interview material divided into attitudes on tourism effects and responsibilities.
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..
Finansiella nyckeltalens samspel som investeringsstrategi : En kombinationsmodell för att uppnå riskjusterad överavkastning
This study is based on a statistical analysis of fundamental key ratios on the Stockholm Stock Exchange during the period 2004-2012. In total 35 financial ratios of 90 companies were tested, ultimately five ratios remained within the 5% significance level. These ratios were ROA, P/B, Total Yield, EV/EBIT and Operating Margin. A custom made investment model was created based on the purpose to achieve a risk-adjusted excess return. The results in general did not show any significant difference in return between the model's portfolio and index.
