Hörselnedsättning hos för tidigt födda barn ? En litteraturstudie
A stay in the neonatal intensive care unit of greater than 5 days is one of the identified risks ofa sensorineural hearing loss. Preterm infants usually have at least one risk factor for hearingimpairment. The period from 25 weeks' gestation to 5 to 6 months of age is most critical tothe development of the auditory system. We think it is important to investigate hearingimpariment among infants born preterm, degree and type of hearing loss, risk factorsassociated with hearing loss and how the auditory system may be affected by preterm birth.ObjectiveA critical review of the current literature including studies of preterm infants born betweengestonal age 25-37. Our aim is to identify the most common type and degree of hearing lossamong infants born preterm and if there is an association between hearing loss and pretermbirth.MethodA literature search of Scopus and Pubmed resulted in 16 articles from 2000-2015ResultsMost of the infants in this study had a severe to profound sensorineural hearing loss.
Kontrollmodul
This report describes the scientific work of designing and manufacturing an intelligent controller module prototype for automobile trailer connections. The functions of the module are both to drive the lamps and detect failures. The module also contains functions to handle other functions of the trailer. To learn about controller modules the group does extensive feasibility study.The group receives three already existing modules, the functions of the three modules are studied and tested in the lab, this is done too get a overview of the construction. The method used I called reversed engineering, a way of constructing by analyzing constructions already done.When the modules are analyzed, the functions of the prototype are tested and designed without copying the analyzed modules.
Evigt offer eller alltid gärningsman? : Framställning av invandraren i den nätbaserade dagspressen
The purpose of this study is to examine how immigrants are portrayed in the Swedish daily newspapers online reporting. The essay investigates in what context immigrants, as individuals, are made visible and how they and their origins are reproduced. The study focuses on the roles victim and aggressor, and is also investigating potential differences between morning and evening newspapers.Present theories are discursive discrimination, critical discourse analysis, cultural racism, stereotypes and structural discrimination. Adopted methods are qualitative and quantitative content analysis, based on the Global Media Monitoring Project-tool.The results show that immigrants are not individually stereotyped or depicted negatively, but that their immigrant origins often have a central part of the story, that they are mentioned mainly in connection with negative news and that negatively charged words occur frequently. .

Varför svänger stenen? : En studie i curlingens komplexa tribosystem
The tribo system ice-curling stone was investigated in order to understand the mechanisms behind the stones' behavior on the ice sheet. The problem with non-identical stones should also be addressed.The stone curls, that is, its sliding path deviates from a straight line to the right for a clock-wise rotation and to the left for a anti-clock-wise rotation. Several mechanisms to explain this behavior have been proposed over the years but none has been successful.By carrying out experiments at the local curling rink and studying silicon castings of ice- and stone-surfaces with scanning electron microscopy and vertical scanning interferometry, it has been decided that the curl is not due to dry friction, ice-debris or the difference in friction on the left and right side of the stone. The side force comes from the fact that the friction is higher at the back of the stone than at the front.The contact between stone and ice is never completely dry, nor in the hydrodynamic lubrication regime. It is probably a combination of hydrodynamic lubrication and a contribution from mechanical scratching of the ice.
Medborgardriven stadsdelsutveckling- Lower Ninth Ward, New Orleans
Through this thesis, we want to discuss how the marginalization of people, several precedent political, city planning- and engineering decisions resulted in a catastrophic outcome after hurricane Katrina in New Orleans 2005. We also put forward a case study of the Make It Right Foundation, to demonstrate how the residents of the Lower Ninth Ward are involved in the urban development of their community. We would like to draw attention to the power of citizens and how they can influence the urban development of a community after a trauma. This study also focuses on the mission of The Make It Right Foundation: which is to rebuild the Lower Ninth Ward with firm concepts on sustainable development where all dimensions are accounted: ecological, social, cultural and economic.
The empirical data was collected by a field study in New Orleans 2010-03-22 and semistructured interviews were made during the same days..

Långsiktigt spårväxelunderhåll - Förutsättningar och möjligheter
Due to their complexity and heavy wear from rail traffic, switches are a sensitive part of the railway infrastructure and moreover expensive to maintain. Furthermore, increasing railway traffic not only accelerates the wear rate but also obstructs the necessary maintenance measures. This paper examines the opportunities for a transition to a long-term maintenance strategy in the Swedish railway network. It contains a study of the maintenance strategy of Banverket, and also analyses statistics of errors in the railway infrastructure. The survey was completed utilising interviews with infrastructure managers, maintenance contractors, planners of railway operations and the Banverket material service department.
Byggprojektstyrning med hjälp av dator -Studie utförd vid byggföretaget NCC
Styr is a computer program that the construction company NCC use in their construction projects. The program is used to keep the economy of their projects in a good order and things for the best in an early phase. The problem is a low extent of utilization. During the latest decade NCC has put a lot of job and money trying to develop the program. The question is how to get the employees to use the program in a greater extent.

services for the citizens. In this bachelor thesis we are studying a increasing
group users, namely elderly citizens. During the study we have analysed
E-governments ser-vices usability through usability tests. The combination of
conversations and meetings with individuals, observations of interactions and
literature studies give us the opportunity to explore the users needs.
Gruppdynamik, medtävlare samt tävlingssituationer : En motivationsfaktor till ökad prestation
Forskningen angående gryppdynamikens inverkan på högintensiv träning är liten, vilket skapar problem i samband med den ökade träningstrenden. Det har nu uppstått en ny arena att forska på.Genom experimentella studier studerades individers motivation samt prestation i olika försatta situationer. 10 deltagare utförde samtliga under sammanlagt tre tillfällen ett förutbestämt pass under olika förutsättningar (se bilaga 1). Studien innebär således tre likadana passutföranden.Genom intervjuer samt kartläggning av tider sammanställdes data vilken kom att beskriva samt förklara hur och varför deltagarnas prestationer kom att skifta. Resultatet kom att analyseras med hjälp av studiens teoretiska ramverk angående tävlingssituationer av Weinberg & Gould (2011) samt flertalet motivationsteorier.Studien visar tydliga samband på att prestation samt motivation ökar då deltagarna utför passen med medtävlande, samt i större grupper.
Projektverksamhetens"early-warner"- en jämförande studie om projektcontrollerns funktion
Background: The project controller is a function witch evolved due to the strong gaining ground of project operation. Why the area of the project controller is interesting to study is explained by the fact that increasing knowledge of this function is important in order to make project operation work well. The fact that opinions in this field disagree, further increases the interest of the field. In order to study the function of the project controller three companies have been singled out. They are IFS, Intentia and Saab Bofors Dynamics.
Affären Astoria Cinemas: Om en biografkedjas korta levnad
In May 2005 the Swedish cinema chain Astoria Cinemas is founded and in July two years later the company goes bankrupt. In this thesis Astoria Cinemas is used as an example to illustrate the conditions for a culture-producing company in a commercial market. The purpose of the thesis is to discuss the strategies for cultural production that has been used by the actors involved in the Swedish cinema market, and also to discuss the structural environment on that market. It is a qualitative study based on interviews and documentation. A few conclusions are possible to draw from the empirical material, one is that Astoria Cinemas? management did not agree on the company?s business strategy and therefore might have acted strategically inconsistent.
SSP : En kvalitativ studie av ett samarbete mellan socialtjänst, skola och polis
This thesis has examined a co-operation called SSP, between the social authorities, the school and the police, located in Malmö. The intention with SSP is to prevent crime and drug use among juveniles but also to evolve a structure for a long-term co-operation between the authorities.The purpose of the thesis was to understand and analyse what the co- operation represented and stood for. The study also examined how the co- operation was effected by differences in the organisation of the three parts.The main questions were the following; what does SSP contain, is SSP preventive and for whom, what motivates the co-operation and how is the cooperation effected by the view the authorities have on the target group?The method used for answering the questions was based on qualitative interviews with the three authorities involved. We have also searched for literature on the subjects involved.The main content of the thesis has showed that the limits of SSP are diffuse, and the focus of the co- operation lies at a structural level.
Price adjustment and vacancies on theStockholm market ? Estimation of rent levelsdue to office-allocations
The Stockholm office market segment have for a long time been considered a safe havenwhen it comes to withstand negative turmoil in the form of rental compression due toeconomic fluctuation, especially in the CBD demographic. Recently however, a large numberof banks and institutions, amounting to some 200000 square meters, have decided to relocateto more peripheral locations with the aim of cost reductions on rent. This mass exodus isstudied with focus on rental dynamics as the result of increased vacancies. Other variables arestock changes and employment. The method is econometric combined with an interviewseries.
