Kvalitet: självklar måttstock eller förlegat tankesätt? Sju inköpsansvariga bibliotekariers syn på kvalitet i musiksammanhang
This master thesis focuses mainly on the concept of quality and how the librarians responsible for phonogram purchase use it. The main object is to investigate how the librarians responsible for the purchasing of phonogram works when in the process of selecting the phonograms and how they speak about the concept of quality. Based on this main object four problems has been addressed. The empirical material is interviews made with the seven librarians responsible for phonogram purchase at seven Swedish libraries. The result of this investigation is analyzed based on a theoretical framework created by Sanna Talja, which focuses on what a phonogram collection should contain.
Får vi se ? datakvalité. Effektivisering av supportprocessen hos Tunga Maskiner AB
Inadequate data quality has a negative effect for organizations, however utilization of modern technology and data analysis may shape new values for organizations. Our research has found that the quality of information in field reports for error reporting varies significantly. In many cases, the information in the field reports are deficient in such way that the field report need additional information from the sender, thus risking prolonging lead times in the error reporting process. More efficient use of information has become possible with today?s technology.
Effektivisering av den administrativa delen av orderprocessen : En fallstudie på Sandvik Wire
Sandvik Wire needed a review of the administrative part of the order fulfillment process and especially the work around packing and the inventory of finished goods. Therefore we acquired the assignment to investigate the administrative part of the order fulfillment process in the company with the purpose to identify potential for improvement. This investigation was performed with focus on the terminal and packing functions. The purpose with the investigation was also to identify critical factors for an efficient order fulfillment process and investigate if information quality is such a factor.Data was collected through interviews and observations on Sandvik Wire. With the help of this data the information and material flows was mapped, the work within terminal and packing, and adjacent functions was investigated.
Effektiv mätning av livskvalitet - Brunnsviken Brief Quality of Life Inventory (BBQ) : en psykometrisk utvärdering
Målet med Brunnsviken Brief Quality of Life Inventory (BBQ) är att skapa en kortfattad och lättadministrerad skattningsskala för självupplevd livskvalitet med goda psykometriska egenskaper vilken är gratis för alla att använda. I framtagningen av BBQ har data insamlad med Quality of Life Inventory (QOLI) i tidigare studier använts för att identifiera de livsområden med störst betydelse för självupplevd livskvalitet. I aktuell studie har normvärden tagits fram för den i studien ingående undersökningsgruppen bestående av 167 psykologistudenter. Studien har visat att BBQ har utmärkt reliabilitet (test-retest), 0,89. Vidare hade BBQ lika god validitet för undersökningsgruppen som QOLI.
Orsaker och sammanhang kring avvikelser i processen med prefabricerat byggande
The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
Nötkött : kriterier vid inköp av nötkött i restaurangbranschen
Swedish beef production has during the past year decreased while the consumption has
increased. It´s imported beef that takes market shares. The purpose with this degreeproject is
to investigate if the restaurants in Sweden are using imported or Swedish beef and the reason
for their choice.
The purpose is to find out if there is something the Swedish beef producers can change to
increase Swedish beef in restaurants. My expectation is that the demand for Swedish beef will
increase in restaurant and later even among consumers.
I have interviewed ten chiefs in different restaurants and asked them the following questions:
Is it the price, quality or something else that influences your choise?
Does it matter to their customers if they serve Swedish or imported beef?
How is the marketing of Swedish beef?
It appeared both Swedish and imported beef on the restaurants.
Riskmodell för kabelsträckningar i mellanspänningsnätet i Sverige
The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.
Inverkan av transgena grundstammar på fruktkvaliteten hos icke-transgena äppelsorten ?Jonagold?
Gene technology has become more and more attractive in plant breeding during the last twenty years. This is probably because it can readily improve the existing commercial cultivars that have only one or a few drawbacks by modifying one or a few genes without changing the main genetic constitution. In this regard, gene technology is more effective than conventional breeding.The aim of this project was to analyze the fruit quality of the non-transgenic apple scion ?Jonagold? grafted on non-transgenic and rolB-transgenic apple rootstocks. The rootstocks used were M9-rolB1, M9-rolB2, M26-rolB and non-transgenic controls M9 and M26.
Om leken i nödvändigheten
This study aims to examine play as a phenomena from a phenomenological approach. This I do by discussing a dominant approach to play, an perspective which is reproduced in the context of pre-school and in where the play and learning is in single focus. Using alternative perspective on play, mainly by Gadamer and Bakthtins philosophical thoughts about the feast or the carnival, contents differ significantly from educational or developmental psychology perspectives. I open up for an understanding of what play as ontology can be understood as, and thereby enable second readings. I illustrate this thought by an empirical example from a pre-school context which where created alongside with the children in the study.
Transformatordiagnostik genom dissolverad gasanalys
The transformer is one of the most common and most important electric machines for power companies. Cost of investment and the economic worth of a transformer are counted in millions of SEK. Because of that, proper maintenance actions that may lead to longer technical life time should be the aim in all situations.The aim with the report was to perform transformer diagnosis by dissolved gas analysis on Umeå Energi AB´s power transformers and a risk assessment. The report should also contribute to longer life time for the transformers.Oil samples were taken from each transformer two times. The first sample in summer 2013 and the second in April 2014.
Drivförstärkare : Bredbandig drivförstärkare med hög verkningsgrad
This report present the design and manufacturing of a wide-band driver amplifier placed in radar module for airborne applications. The major goals for the amplifier were a high efficiency and to deliver a predefined output power. To reach the second goal an additional preamplifier had to be constructed. The amplifiers were constructed in three steps: Design and Layout in the software Microwave Office, Mounting components and Verification. The driver amplifier was decided to be a push pull configuration consisting of two parallel transistors biased in class AB.
Påverkan av skuggor från vindkraftverk
To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow flickering. When the sun is low and the wind blows in a direction so that the rotor blades are positioned at right angles to the sunbeams and ?cut? the sunbeams off.
Luftmakt : en komparativ studie mellan centrala luftmaktsteorier och svensk doktrin för luftoperationer
Att utnyttja flygstridskrafter har sedan tidernas begynnelse varit en effektiv metod att påtvinga motparten sin egen vilja. Sättet man använt flygstridskrafterna på har debatterats under historiens gång. Inom ämnet luftmakt finns det en rad kända och inflytelserika luftmaktsteoretiker som alla har sin idé om hur man bäst utnyttjar flygstridskrafter. Hur ser vår svenska doktrin ut gällande teorier kring luftmakt? Vilka luftmaktsteorier genomsyrar grundtanken bakom hur vi idag vägleder våra luftoperationer? Syftet med uppsatsen är att undersöka vilka generella och centrala luftmaktsteorier som återfinns i den svenska doktrinen.
Barnverksamhet för alla? En studie av barnverksamheten vid två folkbibliotek ur ett genusperspektiv
Abstract: The aim of this study is to investigate the attitudes towards the labour movement?s strategies, goals and organisational issues in Swedish Miners? Union?s (Gruvindustriarbetareförbundet, hereafter Gruv) paper, Gruvarbetaren 1917-1925.The theoretical starting point is Engels? view on the class state. This perspective turns the question of socialism and the way to get there into an issue of working class power over the state. Another theoretical perspective is the partition of the labour movement into a trade-unionistic branch, seeing unions as financial organisations of interest, and a pro-state one, considering unions as political organisations.During the period investigated Gruvarbetaren was quite radical and advocated a firm class struggle strategy towards employers. Since these were considered unreliable, class struggle was seen as the only way to better the conditions for the working class.
Regaining power through construction of identity? Experience of Multisystemic Therapy from a Youth?s Perspective
Literature and studies exist on how to create services in the best interest of the client or how these services have an impact on individuals. They are however mainly from a social work professional stand point and rarely from how clients would develop and create the services that can imply a life change for them. Especially when working with children under 18 years old issues of agency and age that can result in the disregard of the Convention on the Right of the Child (UNCRC). The target group of this study is therefore youth between the ages of 15 to 17 years old in three cities across Sweden to allow them to voice their opinion and experience of being in treatment. Resulting from that is the aim of this study ? to investigate how an intensive treatment method like Multisystemic Therapy is described from a client?s point of view.
