Den synliga övervakningens effekt
The purpose of this essay is to explain which factors influence the disciplinary effect of visible constant surveillance on the people under surveillance. In order to do this we have used recorded video from a tv-show called Big Brother, which is characterized by this kind of surveillance. In addition, an open-ended interview was performed with one of the participants from the show. We have, based on a number of theoretical assumptions, as well as reflections from the interview, precisely defined expected symptoms of the participants, that would indicate when the disciplinary effect was low respectively high. Our observations and analysis allows us to conclude that the disciplinary effect of surveillance in many situations is counteracted when surveillance is constant, leading to relatively low levels of disciplinary effect in Big Brother..
En IT-baserad plattform för skolförbättring : En kvalitativ studie av lärares informations- och erfarenhetsutbyte
This thesis has created an image of the exchange of information among teachers in the Swedish upper secondary school. The study indicates that the exchange of information seems to be limited at all levels and the exchange that takes place outside the own teaching team occurs mainly through teachers personal networks. The study also shows barriers that may exist and the opportunities that an increased exchange may generate. From the picture that the empirical material provides and the theory that is presented a discussion is made around how IT can best support the organizational learning in schools. A concrete proposal is that at national level an IT platform should be created, which primarily focuses on materials that are created by its users and has an open architecture with a single login..
Omega System Kalibrering: Strål X-Separation mätning och kalibrering
Micronic Laser Systems AB produces and develops machines for the photo mask production market. One of their products is the Omega machine which exposes photo masks using 5 laser beams simultaneously. It is important that the distance between the each laser beam, the x-separation, is the same. The x-separation is today measured by exposing a photo mask with a certain pattern and thereafter measured with a metrology system. This takes to much time and it is desired to find a faster method to measure the x-separation without loosing precision.The task for this master thesis is to improve an existing measurement method which uses a calibration mask.
"Alla känner alla" : En studie om musikbolags relation till media
The purpose of our study has been to analyze the character of the interaction between music labels and media and to examine to what extent the artist brand is being considered in music labels relationship with media. This has resulted in our research question:What characterizes the large music labels relationship with media?For this study we have used a qualitative approach to achieve a deeper understanding of our chosen topic. We have conducted seven interviews with representatives from both major record labels and media companies with great knowledge about our subject. Five of the interviews were conducted face-to-face and two were performed via e-mail.In the final chapter we answer our research question and thus present our conclusions.
Vårdnadshavares attityd, beteende och upplevda kunskap om ljudexponering och dess risker
Background: From a public health perspective it is of great interest to prevent the risk of noise induced hearing loss, because in addition to hearing loss, tinnitus and sound sensitivity also may lead to other health problems. About 1,4 million people in Sweden live with some form of hearing loss and 25000 of them are children under the age of 16. Studies have shown that hearing loss among adolescents is increasing and it is often associated with sound environments in their leisure time. Lectures in hearing prevention has been conducted in schools for adolescents but have not reached the desired results. Objective: To enquire caregivers? attitude, behaviour and perceived knowledge about sound exposure and its risks.
Intern marknadsföring - i ett tjänsteproducerande IT-företag
The purpose of this thesis was to describe how service producing IT- companies handles their internal marketing. We wanted to understand how management deal with internal marketing activities and how different companies create a working environment to encourage employees to motivation and well-being. To be able to find out we did a case study on a service producing IT-company. Two personal interviews were done with two of the managers. Our empirical research showed that the company used internal marketing on a daily basis.
Påverkan på Valboåsen från verksamheter inom Svedens industriområde samt närliggande områden : hot mot grundvattnets kvalitet och kvantitet?
The aim of this work was to find out what potential contaminants from roads, residential area and businesses within Svedens industrial area that can affect groundwater quality and quantity. Data collection was from SGU, VISS, internal material from Gävleborg county Administrative Board and Gävle municipality archive. GIS software ArcGIS was used to create the map images in the work.
The studied area is located approximately ten kilometers west of Gävle city and consists of the esker Valboåsen, which is a glacifluvial deposit that in its central parts consist of coarse material that is overlaid by sand, clay and silt. North of esker Valboåsen there are the river Gavleån which has an inflow to the groundwater in the esker. This inflow represents the largest part of the groundwater recharge.
Utvärdering av försvarsspecifika radiovågformer
To be able to evaluate different radio waveforms in a laboratory environment FOI in Linköping has developed an experimental system for radio communication called Rasmus. The system consists of a transmitter, a channel emulator and a receiver. The transmitter modulates a digital signal to a desired analogue waveform. The channel emulator is used to simulate a real radio channel. The channel emulator distorts the signal by splitting it up in several propagation paths.
Nedbrytning av propylenglykol i uppsamlingssystem för avisningsvätskor : En studie utförd vid Stockholm Arlanda flygplats
Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.
Planering av vägupprustning med hjälp av GIS och optimering : en fallstudie på Holmen Skog
The objective of this thesis was to develop a method for the planning of road upgrading at Holmen Skog, a Swedish forest company. A critical issue for creating such plans is to identify roads that are suitable to upgrade to a standard that can handle heavy traffic during spring thaw, since spring thaw is a bottle neck for transporting timber. The method was tested in a case study at a district.
The work consisted of two parts. The first was to retrieve and prepare geographical data for the roads.
The pig as an animal model for type 1 Diabetes Mellitus ? with focus on carbohydrate and fat metabolism
Diabetes mellitus is an endocrine disorder affecting a range of different mammals, including dogs, cats, horses and humans. Worldwide, 347 million people have diabetes, and the disease is an increasing burden on the world?s poorest countries. The disease is characterised by chronic hyperglycaemia and afflicted individuals experience increased thirst, polyuria and weight loss, sometimes despite increased appetite. Diabetes mellitus is either insulin dependent or non-insulin dependent.
The laboratory rat : improved welfare for mothers andpups through breeding in an enriched environment?
Maternal behaviour is crucial for the development of the rat pups? behaviour and stressresponses later in life. There are numerous studies evaluating the effects of the dams?behaviours on the pups, but not many addressing what can be made for wellbeing of the ratdams when breeding. Few studies have addressed the question of how the commonly usedrearing environment effects the dams? behaviour and in the long run how it effect the ratsreared to become our research models.
Utvärdering av koldioxidmätaren Vaisala GMP343 samt sambandet mellan grundvattennivå och koldioxidavgång från torvjordar
The research group Soil and Water Management at the department of Soil and Environment at theSwedish University of Agricultural Sciences in Uppsala are studying greenhouse gas emissions fromcultivated peat soils. To measure carbon dioxide emissions from peat soils in the field the researchgroup are now using two portable carbon dioxide meters (Vaisala GMP343). For practical reasons,they plan to acquire a new type of automated field meter. The aim of this study is to evaluate thepresent meters to see how environmental conditions and instrument settings affect the results,which is meant to facilitate the introduction of the new field meter when the meters needs to becompared. As a part of the study the relationship between groundwater level and carbon dioxideemissions from peat soils will be investigated.The evaluation of the two carbon dioxide meters was made by connecting them to one single airtightsystem, with the aim of creating identical measurement environments.
Ordermusiken
This thesis strives to demonstrate my increasingly phenomenological approach to musical composition in relation to the extensive body of musical works connected in different ways to the poetry collection ORDER by the Swedish author and play-wright Lars Norén. The hand, the touch, the voice, the space (environment) and its philosophical implications are scrutinised from a poetic perspective (my poetics). The question of language (the word), the sign (text), sound/noise/music and its immanent bodily qualities are focused and questioned in my own work as well as in primarily two case studies of the music of Pierluigi Billone (1960-) and Morton Feldman (1926-1987).The text reflects the emancipatory process my music has undergone the last 4- 5 years: moving away from language and text (representation) to body and sound, although preserving and nurturing the extended idea of the sign (as signification of sound and body) as a possible embodied vehicle in my composing and artistic thinking.The reader is invited through the extensive use of sketches and work methods to witness and follow this process as a manifestation of the ?doing? rather than the presentation or construction of an analysis in an academic sense.The thesis offers no solution and it fails to encapsulate all of the so-called ORDER-MUSIC (the music that is connected with Norén's collection of poetry) Instead it proposes a possible way of ?opening? the process to a basically phenomenological methodology inside the musical field of score based chamber music..
Vattenkvalitén i Fredstorpsbäcken - dikad bäck på fastigheten Rämningstorp i Skara kommun :
The estate of Rämningstorp in the region of Västergötland in southern Sweden is administered by the holding trust company Skogssällskapet i Skövde. In 1999 measures were taken by Skogssällskapet to drain the stream Fredstorpsbäcken as a means to increase the forest productivity of the surrounding lands, which are situated on the estate of Rämningstorp. Almost immediately after the drainage, the streamwater turned turbid and a landowner downstream reported the issue to the county administrative board of the region.
The aim of this thesis was firstly to analyse the suspended matter that appeared during summer/autumn and secondly to explain why it came to be. Initial hypotheses for the explanation to the greyish turbid water were that it was either 1) a chemical/biochemical precipitate, or 2) an bacterial/algal blooming.
