Konsumenters synsätt på ekologiska livsmedel avseende frukt, grönsaker & rotfrukter : - En tvärsnittsundersökning ur ett konsumentperspektiv
Background: Pesticides in conventional food may be related to morbidity and mortality. Furthermore pesticides have a negative impact on the whole ecosystem. Organic food can presume better health as they contain less chemicals and toxins and contribute to sustainable development efforts.Objective: The aim was to examine what attitudes consumers have regarding to purchase organic fruit, vegetables and root vegetables.Methods: The association between consumers? views on conventional food and organic food was investigated using questionnaire given to a population sample of men and women aged by 23-65 (N=60) in grocery stores and in a fitness center. The study was based on a cross-sectional study in a municipality in central Sweden.Results: Consumers were interested to buy organic food.
Hållbar utveckling: Hjärtefråga eller nödvändigt ont? ? Miljöarbete hossvenska SME-företag i konfektionsbranschen.
The aim of this thesis is to give an insight to how work is being pursued within Swedish SMEin the clothing industry. Furthermore we investigate how efforts can proceed withenvironmental questions in a quest for sustainable development and bring clarity in thedifficulties that occur. Through the use of company examples and a description of how theywork we wanted to give stakeholders knowledge in what resources and procedures that areused today on the market. The function of the report is moreover to provide Swedish smalland medium-sized clothing enterprises suggestions and directions of how to advance withinsustainable development.In our theoretical frame we have chosen to administer the theories that we found suitable forour study. Seen from a perspective of sustainability we have thus applied the theories ofstakeholder and legitimacy, an analysis model for a company?s actions in environmentalquestions and the theory of SME which describes a small or middle sized enterprise?s fivecompetitive variables.The empirical frame we acquired for this thesis is presented in three chapters.
Vatten som säkerhetsfråga : Med FN:s konstruktion av vattenfrågan som utgångspunkt
ABSTRACTThe aim of this study is to analyse if the UN today constructs the water issue as a security issue and to argue about in which way the organization in that case does so alternatively why it can be said that the UN doesn?t construct the water issue as a security issue.In order to reach this purpose the following questions will be answered:?Does the UN construct the water issue as a security issue today?-If yes, in which way?-If no, why can it be said that the organisation doesn?t?The methods used are qualitative literature studies of policy documents on water from the UN. The focus is to analyze the ideas about water and to apply my theory on the concept of security, which is Barry Buzan?s framework on security, to these ideas.The main results showed that the UN strongly constructs the water issue as an environmental security issue for environments and species and in relatively strong terms also constructs it as an environmental security issue for civilisations. In rare cases the organisation constructs it as a societal security issue, but the UN doesn?t construct the water issue as a military, political or economic security issue..
Renovering av flerfamiljsbostäder inom miljonprogrammet ur ett energi- och lönsamhetsperspektiv
Miljonprogram is a Swedish building program from 1964 to 1975. During that time about a million homes were constructed. Now, almost 50 years later, they are in desperate need of renovation. In order to fulfil the Swedish environmental objective to decrease energy consumption 50 per cent until 2050, considerable housing stock built under the Miljonprogram has to be renovated.Focus in this thesis is on the building services and theirs profitability that can decrease energy consumption in households build during the Miljonprogram. Building construction is not considered in this report.
Surhetstillståndet i bäckar uppströmskalkdoserare i Dalarnas län
The acid deposition of sulphur- and nitrogenoxides from combustion of coal and oil cause acidification that lowers pH and gives increased contents of metals and altered aquatic biodiversity in the stream. The liming of lakes and streams, which was introduced to resist the acidification, demand large economic resourses despite of the decreased deposition of the acidifyng substances. Some of the streams are influenced by the acid deposition, while others are naturally acidic. It is therefore importaint to separate the anthropogenically acidified waters from the naturally acidic, in order to optimize the use of governmental fundings for liming. This thesis aims to estimate the acidity status and impact of acidification on 24 catchments upstream liming dispensers, which is part of the liming activities at the County of Dalarna.The acidity status of the streams was classified according to the Swedish Environmental Protection Agency old classification system (Naturvårdsverket 1999) as very acid to acid, with small ability to withstand a pH-change (alkalinity) due to acid deposition.
Hållbar avfallshantering : Ur ett ekonomiskt- och miljöperspektiv
Economy and environment has for a long time been studied separately and seen as incompatible. With a growing society and increasing pressure on environmental issues the need of a new economy with the environment included is necessary. This study examine if European Union´s picture of the waste hierarchy match the reality. Since the purpose with the waste hierarchy is to benefit environmental and economy. A survey was made over Käppalaförbundets waste from 2013, to see where the waste falls in the waste hierarchy.
Livscykelanalys - en miljöorienterad rapport
Den textila industrin, en egen värld, är nu under rampljuset som en av de största miljöpåverkande industrierna. Precis som i fallet med många andra industrier så måste textilbranschen intensivt arbeta med att minska sin negativa påverkan på miljön. Slutmålet måste vara att helt balansera uttagen och insättningarna så att man skapar en bransch som blir klimat- och miljöneutral. I denna rapport har en livscykelanalys gjorts på en underställströja från Helly Hansen tillverkad av 99 % polypropylene. Inom denna livscykelanalys har vi noggrant studerat och undersökt fakta för att hitta de processer som har den största påverkan på miljön.
Dokumentärfilmproduktion ur ett ljudtekniskt experimentellt perspektiv
This paper is a study of documentary film production with focus on the
filmmakers choice and usage of sound equipment. Using professional articles and
literature have first of all helped us determine a standard for the
conventional use of sound equipment in documentary film. Afterwards, by
analyzing our own interviews we?ve received answers on how filmmakers relate to
the conventional usage and why they select equipment as they do. Thereafter, we
describe a technical method which helps a filmmaker to be able to record sound
for documentary film on his/her own, using simple measures without reducing
quality.
Jobbiga biljetter
This bachelor?s thesis report aims to investigate the problems that exist with the ticketing systems ofthe various regional public transportation authorities, specifically with regards to inexperiencedtravellers and cross-county travel.This is done in part through a comprehensive survey for all of Sweden where both the regional publictransportation authorities and passengers were asked about their opinions, as well as a throughin-depth survey focused on the counties of Stockholm and Uppsala. The results of these surveys arethen compiled and analyzed to identify the biggest common problems.The tree biggest problems prove to be a complicated implementation, lack of availability and lack ofinformation. In order to improve the ticketing system it is therefore proposed to implement asimplified ticketing system, as well as improved accessibility and information. .
Etisk Shopping : En studie av unga mäns tankar kring etiska dimensioner av klädkonsumtion
In contemporary public debate there is currently a great deal of focus attached to environmental problems and social responsibility. This trend is noticeable within the clothing industry, where it has become increasingly popular for new brands to market themselves with an environmental and ethical profile. An anthropological approach has been used to investigate how individuals understand ethical dimensions of clothing, and relates to the consumers? ideals that are pronounced by clothing companies with an environmental and ethical profile. Interviews have been conducted with young men, a group often absent in accounts of ethical consumption.
Diskkrypteringsprestanda i GNU/Linux
This thesis compares the impact on disk performance in a GNU/Linux environmentwith three encryption algorithms: AES, Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that is drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..
Framtagande av ställbar krok för hängränna
The purpose of this project was to design an adjustable gutter bracket for Lindab Profil AB. Lindab currently manufacture a gutter bracket that is adjustable in angle, however, this model has some drawbacks. One of it´s shortcomings is that it is somewhat difficult for the customer to mount. Another problem with Lindab?s current model is that the design makes manufacturing unnecessarily complex. The new gutter bracket, that we have constructed, does not have these problems. It is adjustable for different roof pitches.

The impact from pre-M&A resource allocation on the post-M&A performance
Background: When firms grow through acquisitions it is commonly debated whether the two entities ought to be better off as standalone companies rather than as a merged company. This thesis aims at discussing this issue of M&As advantages and disadvantages in terms of source of synergies from the perspective of resource allocation. Purpose: The purpose of this thesis is to describe and analyze to what extent pre-M&A differences (against similarities) in resource allocation and corporate culture between the acquiring and target firm have an impact on the post-M&A performance. Theoretical framework: Efficient market hypothesis, resource based view, strategic fit. Methodology: A longitudinal study is conducted on the EU market during 1992 to 2002 based on balance sheet and income statement data.
