AVREGLERINGEN AV APOTEKSMONOPOLET. En studie av de enskilda aktörernas förutsättningar att verka på den svenska apoteksmarknaden
With the globalization, companies in the West chose to shift production to developing countries to cut down costs. This had a major impact when child labor and very poor working conditions in these factories were discovered and led many companies to take responsibility for their suppliers and the employees by adopting voluntary so-called Codes of Conduct.There is a subtle balance to enforce improvement of working conditions for employees at suppliers´ factories and to keep costs down. On the one hand, companies would like to conduct extensive audits at their suppliers to ensure code of conduct compliance and thus protect their legitimacy. On the other hand, audits are expensive so companies would like to minimize audits to keep costs down. Companies thus have to strike a delicate balance in relation to how many and what suppliers they choose to audit.
Automatisk Identifiering av Inandningspauser i Spontant Tal - ett HMM/ANN-hybridsystem i Matlab
This thesis presents a system which has been implemented to satisfy a need in theresearch on how speech planning interacts with syntactic and prosodic structure inspontaneous speech. The long-term purpose of the research is to provide models forautomatic parsing of spontaneous speech and for psycholinguistical modelling of speechproduction. Identification of inhalation pauses is an important step in the developmentof automatic methods for spontaneous speech parsing.Identification of inhalation pauses is considered to be a keyword-spotting speechrecognition problem. Hybrid HMM(Hidden Markov Models)/ANN(Artificial NeuralNetworks) approach is applied to this problem. Method gets 90,8% in Recall, 66,4% inPrecision and 76,7% in F-score.

Development of a method for determination of pesticide residues in honey using liquid chromatography tandem mass spectrometry
Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.
Med handen på hjärtat och kniven mot strupen : En kvalitativ undersökning av de svenska bokningsbolagens verklighet
This study focuses on the booking agencies in Sweden and their point of view on the reality with a focal point from the mass media perspective, which says that they have become rather wealthy because of the changes within the music business. The mass media describes the booking agencies situation as golden because of the economical and technological changes that more or less have paralysed the record industry. The study is performed with a qualitative approach and is based on interviews with relevant individuals from eight different Swedish booking agencies. These individuals have been chosen to match as many different segments in the booking agency business as possible. On account of the qualitative approach it is difficult to generalize the conclusion of the study.
Rätt till skadestånd enligt upphandlingsreglera : utformning av beviskraven för ett rättssäkert och ekonomiskt effektivt upphandlingsförfarande
Rules for damages that are effective are important to create legal security and a public procurement that fulfil economic effectivity. Those rules are effectivly created for example when the demand of evidence is possible for the damaged supplier to fulfil. Yet the rules cannot be too low without leading to an uncertain procurement for the public purchaser. Thus one have to balance the interests of a public purchaser against the interests of a damaged supplier. This balance leads to a public procurement involving rules of damages where the public purchaser cannot escape duty of damages just because the demand of evidence is too hard to fulfil..
En gemensam fiende? : -En jämförande studie om olika staters syn på terrorism
Even though terrorism has been on the political agenda for several years there is no general accepted definition of the phenomena of terrorism. Several scientist do also apply that terrorism have changed after the 9/11-attacks. The purpose with this thesis was to analyze and compare the image of terrorism represented by the United States, United Kingdom, Sweden and Norway, in an attempt to draw conclusions about similarities and differentials. The material that was used was these four nations individual counter terrorism strategy. This was made by using idea analysis and self constructed dimensions based on earlier science about security, terrorism and international law.
Metabolit- och hormonnivåer som tidiga markörer för fruktsamhet och produktionsstörningar hos mjölkkor
During the last decades the fertility of dairy cows has declined in the same rate as the milk yield has increased. This is a result of the negative genetic correlation between milk yield and fertility, failure to show estrous signs and metabolic problems in the cow. The purpose of this review was to investigate the function of metabolites and hormones as markers for disturbances in fertility, health and production in the dairy cow. There are several metabolites that are suggested to indicate the cow?s energy balance.
Thailand De tusen leendenas land : En studie om massturismens negativa konsekvenser
The purpose of this thesis is to investigate if there exists a superiority between developed and developing countries, which then in turn effects the negative consequences, for the local inhabitants of Thailand, that follow from mass tourism.To be able to answer the questions that we have selected for this thesis, we chose to perform open interviews with six respondents which were all involved in the tourism industry in Thailand. Four of the interviews were carried out on location in Thailand. In order to deepen our understanding of the selected questions even further literary studies have been made as well. The theories we have chosen concern the topics of imperialism and figurations.Our empirical material gave significant results. It showed that there is indeed an imbalance of power between the western world and Thailand.

Purpose: The purpose is to present a greater understanding of the progression of innovation capital in a technology transfer and biotech start-up context. The findings offer technology transfer professionals, entrepreneurs and academia an overall perception and mental framework of the technology transfer practice and the embracement of a promising invention, building upon its hidden value. Methodology: The thesis was conducted using a qualitative case study, executed with the help of interviews, in order to answer the research question: How is an embryo of innovation capital continuously cultivated in a technology transfer and biomedical start-up process? Conclusions: A technology transfer entity provides the means to establish a platform where an entrepreneur can build its own human capital, structural capital, and relationship capital. The forms of capital interact and thus create value, herein considered as innovation capital.
Identifiering av deponerat material i en deponi samt metodikförslag för upprättande av vattenbalans.
Högbytorp is Ragn-Sells? largest waste facility and it is located north of Stockholm. There is an old landfill still in use, but at the end of this year it will be closed. The waste deposited on the landfill can, through decomposition, give rise to a large amount of methane gas, which is an energy rich gas that can be used for heat and electricity production. To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste.
Work-life balance utifrån ett arbetsgivarperspektiv : Om arbetsgivares arbete och inställning mot work-life balance
I och med att tid spenderad på arbetsplatsen verkar fortsätta öka blir allt mindre och mindre tid kvar till familj och fritid, eller det som i denna uppsats benämns som övrigt liv. Den vanligaste orsaken till att en individ upplever obalans är att arbetssfären är för dominerande och lämnar kvar för lite tid till övriga sfärer. Därför har syftet i denna uppsats varit att öka förståelsen för hur och varför olika arbetsgivare arbetar med work-life balance samt att ta reda på vad de har för inställning gentemot begreppet. Med andra ord ville jag förutom att ta reda på deras inställning även ta reda på vilka olika sätt arbetsgivare arbetar med work-life balance på och vilka nyttor de såg i att göra detta. Detta gjorde jag genom att ta del av litteratur och forskning som berör ämnet work-life balance utifrån ett arbetsgivarperspektiv.
