Polletten har inte trillat ner, ännu? Bankernas hållbarhetsredovisning håller inte måttet!

The voluntary none-financial sustainability report has become a trend within accounting. The environmental issues used to be driven by activists only, but lately it has moved in to the general agenda in many companies. Investors are starting to put more attention to the sustainability reporting as it is considered to add value to the company. There are several standard guidelines to be used when producing a sustainability report, one example is the GRI´s Guidelines that takes the following three dimensions in consideration: economy, environment and social. This Guideline is from an international perspective considered to be of good accounting practice (Ljungdahl 2008).

Kompetensutveckling för gymnasielärare : med inriktning mot El-programmet, elektronik/datorteknik

Syftet med denna studie var att undersöka uppfattningarna hos karaktärsämneslärarna på gymnasiet med inriktning mot El-programmet, elektronik/datorteknik vad gäller de arbetsuppgifter som de utför inom karaktärsämnet, hur förberedda de menar sig vara för dessa uppgifter, samt i vad mån de anser sig behöva utveckla sin kompetens. Vidare var syftet att ta reda på vilken kompetensutveckling som erbjuds för dessa arbetsuppgifter. Studien bygger, utifrån frågeställningen i syftet, på en kvalitativ undersökning med hjälp av intervjuer. Intervjuerna genomfördes med sex karaktärsämneslärare inom avsedda program fördelat på fyra gymnasieskolor i fyra olika orter.Resultatet visar att samtliga intervjuade känner sig kompetenta i sitt verksamma karaktärsområde i och med att de har både relevant utbildning och arbetslivserfarenhet. Men de flesta utför helst inte frivilligt det administrativa arbetet utan de vill ägna sin tid åt den tekniska delen som intresserar dem mest.

Storytelling som marknadsföringsstrategi : AB Enaforsholm

The marketing strategies discussed in today?s literature are often developed for larger compa-nies and are therefore poorly fitted for smaller businesses with little resources, such as the small resort Enaforsholm Fjällgård in Jämtland. Hence, this paper focuses on presenting and discussing the marketing strategy storytelling and whether it is applicable to Enaforsholm Fjällgård. This mountain resort was given to the Royal Swedish Academy of Agriculture and Forestry (KSLA) in 1937 as a trust fund to be managed in the spirit of the grantor A.W. Bergsten.

Lyxvarumärkens överlevnad vid lågkonjunktur : Hur resonerar svenska lyxföretag, och vilka strategier är lämpliga att använda sig av?

 The luxury market has steadily grown from the industrial revolution and onwards. Changes in society, trends and the increased living standards has enabled more people to consume luxury goods.The world is going through a major economic crisis at the moment. Studies shows that companies that have focused on added value rather than lowering prices has survived past financial crisis. It is also obvious that companies act very different during times of crisis. Adding to the problem is trends that point to a more careful consumption and environmental awareness.

Deduplicerings påverkan på effektförbrukningen : en studie av deduplicering i ZFS

Uppsatsen beskriver arbetet och undersökning för hur deduplicering i filsystemet ZFS påverkar effektförbrukningen. En större mängd redundant data förekommer i centraliserade lagringssystem som förser virtualiserade servrar med lagringsutrymme. Deduplicering kan för den typen av lagringsmiljö eliminera redundant data och ger en stor besparing av lagringsutrymme. Frågan som undersökningen avsåg att besvara var hur ett lagringssystem påverkas av det extra arbete som det innebär att deduplicera data i realtid.Metoden för att undersöka problemet var att utföra fem experiment med olika typer av scenarion. Varje scenario innebar att filer kopierades till ett lagringssystem med eller utan deduplicering för att senare kunna analysera skillnaden.

Energianvändning i serverhallar: energiflöden och kylning

This thesis examines different methods for the cooling of data centers. Several means of cooling with the refrigeration cycle have been studied, as well as the feasibility of using free cooling in different parts of Sweden. In addition, the possibilities of transferring excess heat to a nearby district heating system were investigated. It was found that in all investigated cases except two, the data center could be cooled solely with free cooling for at least 300 days a year when only the outside air temperature was considered as a constraining factor. The limit was then set to 20 °C.The vast majority of all district heating systems in Sweden get little to none of their heat from other excess heat sources.

Redesign of an existing apartment block in Kv Preussen to passive house

Passive houses are a relatively new concept in Sweden and by that it is meant a house without a traditional heating system. The most acknowledged passive house project is the terrace houses in Lindås, Gothenburg, which we have used as a reference. This project concerns a square apartment block. So far, no square apartment block has been built as a passive house in Sweden.The common opinion in the construction industry is that it is not economical to build extremely energy efficient houses. With Peab as commissioner our task was to investigate if that is true, if regarding the construction of a multi storey house as a passive houseMidroc, now owned by Peab, constructed in the block of Preussen in Jönköping during 2004-2005 four houses, with 132 apartments distributed on seven floors.

Småskalig biobränsleeldad kraftvärmeproduktion : teknik och investeringsutrymme

To achieve the requirements to decrease emissions of greenhouse gases by 20 % by 2020, Swedenneeds to increase its use of bioenergy. In doing so it seems natural that those who already haveaccess to large amounts of biofuels in the form of by-products such as straw, wood chips anddigestible materials take advantage of these assets locally. By combining production of heat withpower production at the farm it may be possible to not only reduce the direct use of fossil fuel forheating but also reduce energy costs.The purpose was to simulate different cases of using a small scale biofueled combined heat andpower plant for farm-based systems. A MatLab-model was developed and used to draw conclusionsabout the costs for production of heat and electricity with different conversion technologies.The model uses climate data to simulate the variations in heat energy demand on a day-to-day basis.The given heat demand is the base of the simulation and from this the possible electric output iscalculated. This study has focused on the impact of the following properties: electric-, heat- andtotal efficiency, fuel, fuel price and specific fuel requirements.

The Complexities of Lifestyle Brand Segmentation - A Study of the Lifestyle Brand Converse

This master thesis takes its point of departure in the conflicting worldviews of modernism and post-modernism. As traditional segmentation theory springs from the modernist worldview, this study aims to contribute to the understanding of the complexity regarding market segmentation for lifestyle brands in contemporary society, where the consumer is often claimed to be post-modern. The research was conducted in Malmö and Lund and involved 25 Converse users as respondents. The methods used in this thesis starts with observations as a sampling technique in order to locate the respondents. Short interviews and photo documentation followed.

Installation av magnetiseringsutrustning för bränsle på en dieselgenerator : Kan det sänka bränsleförbrukning och emissioner?

Denna studie avser att ta reda på om någon förändrad effekt kan fås gällande bränsleförbrukning och emissioner då dieselolja strömmar igenom ett magnetiskt fält innan det förbränns i en dieselmotor som driver en generator. Utrustningen som ger upphov till magnetfältet har tillhandahållits av ett kommersiellt företag. Studien består av två delar, en teoretisk del och en praktisk del. I den teoretiska delen presenteras tidigare vetenskapliga studier inom ämnet samt hur tillverkaren av utrustningen menar att tekniken fungerar. I den praktiska delen har tester gällande rökgasemissioner och bränsleförbrukning gjorts.

Möte i månsken : ett belysningsförslag för Fyristorg

The object of the thesis is to propose a new lighting plan for the square Fyristorg in Uppsala, and to describe the process which have led to it. It all started when I choosed the place together with the municipality of Uppsala. I have been doing research and analyzed how the place and it´s existing lighting works both during different times of the day and also in the evening. After researching the place and it´s existing lighting I´ve decided to put up the following goals fot the new lighting design. 1. The general light level of the place shall be experienced as higher than today. 2. The light level of the place shall be adapted to the light levels of surrounding places. 3. The lighting shall be free from glare. 4. The lighting shall be adapted to people passing by. 5.The lighting shall be adapted to the surrounding architecture. 6.

Hållbarhetsredovisningens budskap : en komparativ studie av Vattenfall och E.ON

Companies today are expected to communicate their responsibility to the world around them. Society?s expectations differ and stakeholders are demanding that companies act responsibly on matters related to climate, work environment and human rights. The purpose of sustainability reports is that companies should measure, present and take responsibility in relation to their internal and external stakeholders. It is intended that a reasonable picture of the company's sustainability performance should be communicated, containing both positive and negative effects.Companies efforts with sustainability issues is industry-dependent and industries with significant environmental problems perform the most advanced environmental statement.

Förslitning av fräsverktyg

Sweden is dependent on secure sea transport. Shorter disruption of imports of fuel and crude oil can be managed with an emergency stock, but a prolonged halt in imports creates problems. For industry, the vulnerability is greater. Fragmented production chains in combination with expenditure reductions in inventory causes a dependency on proper transport of intermediate goods in the manufacturing industry. A lengthy disruption thus involves disruption of production for both domestic consumption and for export goods containing imported parts.In order to secure shipping routes with a limited number of vessels, Mine Counter Measures (MCM) capacity is required, and according to the Armed Forces, developed with new sensors and autonomous vehicles.

Att fråga om patienters alkolholvanor. Förutsättningar och hinder för sjuksköterskors engagemang i ett aktuellt folkhälsoproblem.

En miljon människor i Sverige dricker för mycket alkohol vilket kan leda till försämrad hälsa, sjukdom och skador. Sjuksköterskor möter patienter i olika omvårdnadssituationer inom hälso- och sjukvården. Syftet med denna studie var att belysa vad som underlättar och vad som hindrar sjuksköterskor att ställa frågor om alkoholkonsumtion i möten med patienten. Litteraturstudien baserades på 10 artiklar funna via de två databaserna Cinahl och PubMed. Artiklarna har granskats och analyserats och i resultatet framkom tre kategorier vilka har huvudtema och undertema.

Produktivitet och lönsamhet vid skörd av skogsbränsle i klen björkgallring :

The aim of the study was to compare productivity in first thinning of birch stands, when either energy- or pulpwood was harvested. The systems total profitability was also compared by including forwarding and chipping costs. A Gremo 950 HPVR harvester was used and the same driver was used under the entire study. During the pulpwood harvest a Logmax 4000b harvester head was used and a feller buncher head made by Silvatec was used during the energy wood harvest. Six study unit pairs were located in a birch dominated stand outside Ängelholm in Skåne.
