Förbättrad Kravhantering med hjälp av Lösningsinriktad Pedagogik

Abstract The purpose of writing this thesis was to improve methods during requirements engineering phase. Usercentred system engineering has some problem areas, which are examined and verified to create a new guideline for developers. This guideline tends to make requirements engineering more effective and help developers create more concrete requirements. It is not uncommon that system development projects ends up with unsatisfied users or delay in deliveries. The reasons are different kinds of communication problems between users and developers during verification of requirements. There is a therapy model, called solution-focused therapy, used in family and individual therapy. The model focuses on solutions for the future instead of problems in the past.

Aspirantutbildningsprogram

Because of the currently large recruitment needs within the Swedish nuclear powerindustry, it is necessary to recruit trainers from other recruitment groups than that ofexperienced operators at nuclear power plants. The foundation for a trainingprogram regarding these recruitment groups, here called ?aspirants?, has in this thesisbeen prepared. It contains a suggestion for main topics in the program. It also includesdiscussion on the balance between forms of education and a concrete example ofhow a lesson could be performed.These suggestions has been developed through analysis of interviews and surveyresponses from student groups most suited for the propositioned trainee program,and individuals with service as a trainer or closely linked to training activities withinthe industry.The analysis suggests that the candidates gets, besides the opportunity to practice asoperating staff before the theoretical training begins, a training program, tightly boundto the power plant with multiple instances of practice and the chance of going intothe power plant and see how things that are being raised in theory, look in real life.The practice, in addition to helping to create an understanding of the plant, it will facilitate networking with the operations staff to build a relationship and trust.Candidates should have plenty of opportunity to educate and see both other aspirantsand experienced trainers train.

Enhetstestning: Kostnad mot kvalitet

Unit testing is a type of testing technique which is becoming quite fashionable to the developers and companies that are in the business of creating and managing software. Alas there are seldom any concrete data to support the positive claims of the authors in unit testing methodology books. These claims are instead based on empirical studies and the experience of the authors. The problem that arises from this situation is that it becomes problematic for managers and also the developers themselves to convince both customers and their own management to use this type of testing as there is no exact return of investment model. This essay examines this problem from two points, the first point is from the literature itself and interviews conducted with a number of developers at a software company located in Umea, Sweden.

Förekomst av ultra-fina partiklar och partiklar ?10µm vid diatermianvändning med mobilt rökutsug : Jämförelse av partikelnivåer centralt och perifert på operationssal

Flertalet studier har påvisat ett samband mellan koncentrationen av partiklar ? 10µm i luftföroreningar och cardiovaskulär- och pulmonell morbiditet och mortalitet. Vid resektion, koagulering/bränning med diatermipenna under operationer alstras rök. Denna rök innehåller bland annat mutagena och carcinogena partiklar i inhalerbar storlek (partiklar ? 10µm).Ett första syfte med denna studie var att kvantifiera den mängd ultra-fina partiklar (UFP) och partiklar ? 10µm som operationspersonal exponeras för i operationsrummet, vid användande av diatermi med mobilt rökutsug.

Do retention trees affect the composition of ectomycorrhizal fungi? : a comparison between clear-cuts areas with and without retention trees in pine forests

Under det senaste årshundradet har de svenska skogarna genomgått en omfattande förvandling, från mer eller mindre naturligt dynamiska till hårt brukade skogar bestående av monokulturer av tall eller gran. Denna förändring har lett till en minskning av den biologiska mångfalden, att många arter som är beroende av skog har minskat radikalt och hotas av utrotning. Som ett försök att främja variation, biologisk mångfald i allmänhet och förhindra minskningen av rödlistade skogsarter introducerades i början av 90-talet en viss naturvårdshänsyn i brukade skogar. I den här studien utvärderas den påverkan som kalavverkning har och den betydelse hänsynsträd har på artsammansättningen och förekomsten av ektomykorrhizasvampar (EMF) under de första 20 åren efter kalavverkning. Studien utfördes genom extrahering och identifiering av svamp-DNA från jordprover tagna på kalavverkade ytor, nära hänsynsträd och i gammal skog i ett begränsat geografiskt område i norra Sverige.

?Det som skvalper omkring i hjärnan är det som kommer ut.? : En intervjustudie av kompositionsprocessen i folkmusik.

Syftet med denna studie är att ta reda på hur kompositörer inom genren svensk folkmusik idag går till väga när de komponerar ny musik, hur deras arbetsprocess ser ut och vilka arbetssätt de använder sig av. Det teoretiska perspektivet är hämtat från Stan Bennet och Max Grafs tidigare forskning om hur kompositionsprocessen ser ut för kompositörer inom konstmusikgenren. Ett didaktiskt perspektiv används också som utgångspunkt. Bakgrunden till arbetet baserar jag på tidigare forskning om kompositionsprocessen, forskning om gehörsmusik och kreativitet och idé-skapande. Jag ser även till vikten av att tränas i sitt divergenta tänkande som komponerande innebär.

?Man får inte vatten i stövlarna på en gång? : En undersökning om miljöbevakningen i Rapport och Dagens Nyheter i samband med IPCC:s klimatrapporter

The purpose of the study was to find out whether the interaction between mentally disabled individuals and pet positively affects the individual and gives a feeling of well-being to the extent that this might be implicated in the psychologically disabled people?s everyday life in some form of rehabilitation measure. The study is qualitative and builds on an ethnographic design. Data collection was performed through six observations, six interviews and reflections. Interviews were also conducted with relatives and assistants for greater opportunity for follow-up questions, and descriptions of the situation.

Hellre sjuk och mager än frisk och fet : En litteraturbaserad studie av kvinnors upplevelser under behandlingen för anorexia nervosa

BackgroundAnorexia nervosa is a growing problem in society and it is most common among women. It is a complex disease that affects both the mental and the physical health. The disease expresses itself differently from person to person, therefore, treatment should be individualized. Nurses need to gain insight into how patients feel about the treatment in order to understand their experience. Previous studies use statistical research to evaluate treatment.

Entreprenörskapsutbildning för framtiden

Increasing innovation and entrepreneurship has been identified as a key target for sustained growth and welfare, both in Sweden and abroad. Therefore, many countries have recognized the need to equip students with entrepreneurship education and to integrate skills associated with entrepreneurship into the various curricula.To shed light on entrepreneurship education within business curricula, a case study focusing on the first two years of the Bachelor program at the Stockholm School of Economics (SSE) was conducted. The study was based on interviews with students, alumni and scholars with a background of entrepreneurship. Insights from respondents were compared with leading research on entrepreneurship education, to evaluate the program's approach.Primary findings from the qualitative analysis showed an overall lack of entrepreneurship education in the early stages of the program. Entrepreneurial "know-how" knowledge was an insufficient component of the SSE program and a barrier for why more students did not pursue a career in entrepreneurship.

Någon måste göra något! Institutionsplacering: en konkret och för-givet-tagen åtgärd för att hantera ungdomar med beteendeproblem

The purpose of this study was to increase the understanding of the phenomenon that there are so many young people placed in institutions in Sweden despite the valuable knowledge regarding the problems and risks of doing so. The questions that follow in the essay were what guided the social workers to choose institutional placement for youngsters. It went on to also ask if this knowledge could contribute to an increased understanding of why there were so many young people placed in institutions despite the criticism from scientists. To accomplish the goal of the essay, former science in the subject was reported and six social workers within social services were interviewed. The material of the interviews was analyzed with help from the theory of human service organizations, street-level bureaucrats work situation and the new institutionalism.The result of the investigation showed that the social workers choices to place young people in institutions is guided by specific work and organizational factors connected with a belief in the helping function of the surroundings.

Grodsamhällen längs vattendrag på Borneo : En identifiering av habitatkaraktärer viktiga för diversitet och abundans av grodor i tropisk regnskog

The stretch from the riparian zone of a major river, through the mouth and upstream in tributaries forms a range of differing habitats. The aim of this study was to investigate the effect of these different habitats on the riparian frog community in primary rain forest in Borneo; i.e. examine whether any gradients could be demonstrated in terms of species composition, diversity and density of frogs, as well as which environmental characteristics that seem to be of most importance in forming habitats of high conservational value. A major river, Segama, and three of its tributaries were investigated. The surveys were carried out at night by searching for frogs visually and acoustically along the streams, from the shore of the Segama river and 400 metres upstream in the tributaries.

Inverkan av fukthärdning och relativ fuktighet på sprutbetongens krympning

Efterbehandling på sprutbetongen skall enligt regelverk som BV-tunnel och Tunnel 2004 ske direkt efter sprutning. Fukthärdning av sprutbetongen behöver tillämpas då den relativa luftfuktigheten understiger 90 % vid betongytan. Fukthärdning skall då utföras så att betongytan ständigt är fuktig, under hela härdningsperioden fram tills att betongen har fått tillräcklig hållfasthet. Då cementet hydratiseras bildas olika kristaller som ger cementmaterialet dess hårdhet och hållfasthet. Med krympning menas här rörelser i betongen som orsakas av vattenavgång i form av avdunstning från betongen och genom kemiska reaktioner i hydratationsprocessen. Syftet med denna rapport har varit att studera effekten av varierande fukthärdning på sprutbetongen.

Representativa testnät försvenska eldistributionsnät

This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power  istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.

Extraterrestrisk och terrestrisk kromrik spinell i fanerozoiska kondenserade sediment

This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.
