Dominerad av Dominans : en kvalitativ studie om hur pojkar/unga män med rötter i den muslimska världen förhåller sig till etniskt svenska män och vad detta förhållningssätt innebär för deras egna föreställningar om maskulinitet och heder
Islamic masculinity which quite often associates with oppression of women has remained an underexaminated category despite its constant presence in the debate on honour related oppression. Honour has primarily been studied from a feminine point of view and theories of masculinity have taken insignificant interest in the issue of honour. The aim of this study is to understand what attitudes boys/young men from the Muslim world have toward native Swedish men and what these attitudes do imply for their own conceptions of masculinity and honour. The ambition of this study is also to make explicit the similarities, differences and connections between honour and masculinity.The empirical basis of this study consists of twelve interviews with boys/young men from the Muslim world about their notions of honour and masculinity. The theoretical platform arises from theories of masculinities and honour.Some prominent ?patterns? that I have found:- That religious norms and rules appear to be significant in how the masculine manners of conduct should be adjusted.- That honour and women as carriers of men?s honour, play a crucial role for the constitution of proper masculinity.- That the Swedish context and its policy of equality seem to threaten the obviousness of the islamic masculinity.
Kvalitetsförbättringar och Emballageinstruktioner
This report is the result of a thesis carried out at the Department of Innovation, Design and Technology (IDT), at Mälardalen University on behalf of ABB AB Machines.The year was 1988 when ASEA and Brown Boveri formed a joint venture under the name ABB (Asea Brown Boveri).We perform our thesis at the division Discrete Automation and Motion where they primarily develops, manufactures and sells synchronous and asynchronous AC motors and generators.The main purpose of this thesis was initially to write a general packaging instruction, but the priority changed to develop more specific packaging instructions for Rotors, Stator gables, Bearing support and Outer Cover (plates) instead.The work started off to deal with a problem about that the staff had to start its work to grind away rust on the stator gables due to those stored outdoors. The result was mainly an investment in a new gable rack so that the material can be stored inside, as well as a packing instruction as it was originally intended.The problem on the bearing supports were that the staff thought it was demanding and difficult to clean them from the rustproofing they were greased in. If it is not possible to remove all rust protection it can cause the paint to not attach properly. After having compared with similar articles a test were done to order a pair of bearing supports without corrosion inhibitor, which gave good results. This initiative also set in motion a process to do the same for more different items.For special pallet, a survey were made of the process with two different VSM and a calculation of how much ABB would earn at ordering more special pallets than getting the material delivered on the A-pallets.
Energieffektivisering i ett verkstadsföretag : En analys av energibesparande åtgärder samt uppvärmnings- och kylsystems driftkostnader och koldioxidutsläpp
The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.
Innovativt koncept för prognosstyrning av byggnaders värmesystem
Syftet med förstudien var att undersöka vilka parametrar som kommer ha inflytande på en regulator i ett nytt koncept för prognosstyrning av byggnaders värmesystem, och om möjligt även undersöka hur mycket inflytande de har. Påverkande parametrar är t ex utetemperatur, sol, vind, nederbörd och internvärme i samverkan med byggnaders huströghet, dvs. värmelagringsförmåga. Målet var att ta fram dels en specifikation, som beskrev olika driftfall, och dels ett designförslag på en möjlig webbaserad sida i ett av företaget Regins HMI-system (användarverktyg). Användargränssnittet till designförslaget skulle vara enkelt och tydligt att förstå, samt ha en tydlig koppling till energibesparing.Förstudien ?Innovativt koncept för prognosstyrning av byggnaders värmesystem? skulle ligga till grund för en utveckling av företaget AB Regin´s produktsortiment ? resultatet av specifikationen och designförslaget kommer senare implementeras i en fungerande produkt, som skall innehålla både prognosstyrning och val av komfort.Prognosstyrning har funnits sedan 1980-talet och det som ursprungligen skulle uppnås med detta var ett jämnare inomhusklimat.
Fallstudie: en analys av Kungens Kurva utifrån Huddinge kommuns vision för vidare utveckling av området
In this thesis, a case study of Kungens Kurva in Stockholm is made. The municipality of Huddinge has designated the area, which is an external shopping-center, as one of its key development areas in the future. The municipality has established a future vision for the area, which extends until 2030. The vision claims, inter alia, that Kungens Kurva along with Skärholmen will become a vibrant suburb. How well the values and aims of the vision are met in the current area situation is discussed in the case study by a number of analysis that carries out the existing structures and characters of the area.
Maybe it would be better if I was Swedish: En studie av internationella mastersstudenter i Sverige och deras utmaningar och m?jligheter p? arbetsmarknaden
Recent changes in Swedish law suggest new groups of ?desired? labor migrants, which international students is an example of. Despite this, international students in Sweden have received little previous attention in the literature. The current study focused on international master students? experiences of job searching in Sweden and challenges they face in job searching, recruitment, and workplaces.
Kunskapen, professionen och makten ? En kvalitativ studie om socionomens villkor och förutsättningar
My main purpose with this study is to investigate how the social worker relates to knowledge, power and profession. From this purpose has also the concept ?to be a social worker? emerged.The study is based on a qualitative study and consists of semi-structured interviews with seven social workers from different fields of expertise.The result of the study shows that the knowledge is dependent of different fields of expertise. But in the contact with the client, regardless of field of expertise, the knowledge is gathered through a reflective pattern. Through theoretical attempts and earlier experience from social workers, this is brought to life in this unique meeting.

EU:s Fiskeripolitik : På väg mot en rättighetsbaserad förvaltning?
Most of the sea areas within the European Union are overfished and the catches are estimated to be up to five times lager then the amount to achieve a sustainable fishery. In doing so, the management of EU's marine resources comes to be questioned. The purpose of this study was to analyze EU's administration of marine fisheries and to explore which steps that can be undertaken to counteract the negative trend. The questions of the study were: How does the EU administrate today?s marine fishery recourses? And: How can the problem whit overfishing be discouraged? To answer these questions a comparative analyses were used to compare and evaluate administrative systems.
Histiocytära sjukdomar hos Berner Sennenhund :
The histiocytic diseases are generally rare in dogs and not much is known about
the disease. The disease complex that includes both a reactive form and a tumour
form, is however common in certain breeds, among them the Bernese Mountain
Dog. As the literature is very limited on the subject of histiocytic diseases, my aim
with this thesis has been to gather current knowledge of these diseases. I have also
attempted to estimate the frequency of the diseases among the Swedish Bernese
Mountain Dogs and investigate if they appear to be more common among certain
families..
Utredning av frekvensregleringens påverkan på mekanisk utrustning i en kaplanturbin
As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.
Bedömning och betyg : grundskolelärares uppfattningar kring tidigare och tydligare kunskapsbedömningar
The school is under constant change and school reform on the conveyor belt. In 2009 the Swedish government introduced new directives for the elementaryschool, including multi-national sample, written testimonials from grade one and grade with several grades rose from grade six. The purpose of this study is to examine currently active primary teacher perceptions of the pupils' learning and development might be affected by those earlier and clearer knowledge assessments, and how teachers perceive this reform on the basis of the Swedish school's motto "a school for all". The study was carried out with a phenomenological approach where the method has been depth interviews with five active primary teachers from grades one to six in a school. The results show that teachers perceive that the earlier and clearer assessments will affect students differently according to student performance and knowledge.
Profilering av Södertörns Högskola : Studenternas inställning till lärosätets marknadskommunikation
Either if you are a company or a state owned organization, in our case Sodertorn University collage, it is very highly demanded and needed that there is a well-defined definition of the area you perform in. It is also highly recommended that you have an accurate and informal profile of the type of company you are and that you have an effective communication to your surroundings, so that they can perceive it the way the company wishes mediate the message. In this essay we have tried to explain the kind of profile Sodertorn University collage has, and how its current students perceive this profiling strategy.Sodertorn University collage profiles itself through three significant areas: the school claim themselves to be multicultural, multiscientific in an aspect when it comes to courses and programs, and as a school with an ambition to educate and form more critical thinking students. This has become Sodertorn University collages trademark and is quite significant for the school, something that we have examined in our survey among the current students. What we will examine in our essay will only be the two first mentioned components, multicultural and multiscientific programs and courses.We have also had the intention to do a comparison with an earlier essay from 1997 made by two economics students, and put our results in contrast to the earlier results since there were no previous research after this one.
Effektivisering av produktionsgrupp : Improving the efficiency of a production group
The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..
Beredskapsvattenförsörjningen på Sjukhuset i Varberg -En källa till problem?
The hospital in Varberg has a somewhat outmoded solution regarding the state of preparedness in its water sustentation. Today?s solution is both cause to a number of mishaps and high energy consumption.The report is initiated by looking into the present situation to get an insight to the problem.Today?s media depletion is measured and analyzed.Furthermore, it also looks into some earlier performed studies. These studies are followed up in order to see if measures have been taken.The report presents a number of arrangements which should be taken, amongst those a minor re-build of the current solution and a number of arrangements which leads to decreased water consumption..
