Graffiti och Nolltolerans : En kvalitativ studie om graffitikulturens utveckling till följd av Stockholm stads nolltolerans

This study is about howStockholm?s policy for zero tolerance of graffiti from 2007 affected the graffiti culture inStockholm. We have researched what consequences there were for the practice of graffiti, and what consequences there were for the stylistic performance of graffiti. In doing so, we have had two focus group interviews and one deep interview including eight graffiti writers from Stockholm. The individuals in the groups have been practising graffiti for a varied amount of time, but we have representation from both before, and after/during the policy of zero tolerance from 2007. Our study shows that the result ofStockholm?s policy for zero tolerance of graffiti for the graffiti culture inStockholmwas a ?subcultureification?, a ?stylistic generalization? and the ?subculture?s ambivalent identity?.

Parameterstudie av inneslutningsbildning och utvärdering av processföring för tillverkning av plastformsstål

This thesis has been performed at Uddeholms AB with the purpose to investigate theparameters affecting the formation of inclusions during the manufacturing of a low carbonmanganese-steel.A follow-up, steel and slag sampling and evaluations in microscope have been done for a totalof five heats.The results for each heat have been evaluated in relation to the theory from the literaturesurvey and suggestions for changes in the process to reduce the amount of inclusions whichhave a negative effect on the steel quality have been given.The project extends over a large process where many parameters affect the formation ofinclusions. However, a tendency that a higher addition of alloys seems to increase the totalamount of inclusions before and after the vacuum degassing is seen.The majority of the studied inclusions seem to approach the composition of the top slag aftervacuum degassing. Ladle glaze may cause the inclusions which had a different compositioncompared to that of the slag.A high or low ladleage together with a high argon flow during vacuum degassing seems todissolve particles from the refractory which later on get trapped inside the inclusions.The floatation for two heats has been studied where a short floatation seems to give a higheramount of inclusions in casted material.In machined material so called stringers were found. The main composition of those stringerswas pure alumina. Inclusions with a composition of pure alumina were not found in the liquidsteel, thus the pure alumina inclusions must be formed during the casting.

Mellan klass och kön : En analys av det socialdemokratiska kvinnofo?rbundets aktionsprogram 1972 - 1993

The aim of this thesis is to analyse the conceptualisation of the social relations of class and gender within the Social Democratic Women?s Association during the period 1972 ? 1993, on the basis of their programmes for action. The analysis of the concepts is based on an ideology critical study focusing on the manifest ideology.The study is based upon the theoretical concepts of class and gender,  The class analysis is based upon the broadened concepts of class by Erik Olin Wright and Ira Katznelson. The gender analysis is mainly based upon a Marxist understanding and a critical point of view of Marxism and feminism in the context of patriarchy and capitalism.The period of the study is where the social democracy is challenged, both by radical socialism and feminist ideology and the economic crisis during the 1980?s, as well as the possible threat of an organised women?s party in Sweden.

Analysis of CD4+ and CD8+ T-lymphocytes : A comparison between EPICS XL and Celldyn Sapphire

Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.

Elevhälsa: en kvantitativ studie om elevhälsans tillgänglighet i fyra industrikommuner

The aim of this investigation was to determine if, and in that case how, the resources of personne1 in what in this essay will be referred to as the department of students' health in four industrial municipalities had changed from 1999 until 2004. The establishment of the department of students' health could be discussed and analys ed in regard of a few concepts from new institutionaI organizational theory and studies on implementation. The investigation answers the following questions:What differences were there between the municipalities regarding the children's accessibility to the department of students' health?What differences were there between pre-school, compulsory school and upper secondary school within the municipalities regarding the children's accessibility to the department of student's health?The municipalities were commissioned by the government to combine school health service, student welfare and the field of remediaI teaching in order to establish a new section, the department of students' health. The study was carried out quantitatively.

Musikteori på gymnasiet : En studie om gymnasieelevers inställning till musikteori

The transition from having been under another country?s control to becoming a democratic country can, many times, pose difficulties, which has proven itself to be quite common. Estonia and Moldova?s processes towards a democratic regime are two examples of countries with varied success in the final transition phase.When the USSR (Soviet union) fell and collapsed in 1991 Estonia was well on their way from having a communistic ruling to a democratic one due to the fact that their democratic work had already begun a few years prior to 1991. After the collapse Estonia continued with their democratic work and in 2004 the country became a EU member state.

En mångkulturell skola : En studie om främjandet av elevers kulturella kunskaper på en mångkulturell skola

My thesis is based on a qualitative study. The purpose of the study is to investigate whether the educationalist at an especially chosen school in Stockholm promotes the students multicultural background in the education or not.This is due to the fact that the Swedish school to a considerable degree reflects the multicultural Swedish society. The socio-cultural starting point is when people come together and meet. The language is the tool of the socio-culture and it is the dialogue, discussion and sympathetic understanding that makes people meet.The cultural concept is diffuse and very wide. Everyone has their own definition of it.

As part of the plan for the LEAN-work, an LSS (Lean Six Sigma)-project has started to study the company's receivehall and inspection.

Akta er för dörrarna - en observationsstudie av dörröppningar i en hybridsal

SUMMARYPrevious research has shown that there is a connection between the doorways and postoperative wound infections. Despite recommendations from Socialstyrelsen and the individual hospitals' PM there is still high traffic in the operating theatres. In a hybrid theatre environment combined X-ray techniques of surgery, resulting in it being further two categories inside the operating theatre. This may generate an increase in traffic flow. The study is a prospective, non-participant observation study conducted in the spring of 2013 at a university hospital in western Sweden.

"Det var stressigt, man visste typ inget" : Vägledningen inför gymnasievalet, ur ett elevperspektiv

The purpose of this investigation was to study what students in in the first year of the social science program in high school think about the guidance they had access to during their time at primary school. This is to ensure that it the guidance students are entitled to and contribute to the development of the business. The survey was conducted at two different high schools in southern Sweden. A total of 57 students participated in the survey. The results show that 46 and 29 percent of students at the two schools did not feel they had the information they needed for their upper secondary school The results proving what previous research reached that students selection process can lead to stress and uncertainty associated with the choice to high school. The results of the present study showed that girls in particular have high standards for themselves and experience stress and anxiety associated with their selection to a greater extent than boys.

Hur tron finner ankarfäste. Pastorers informationssökande i sin andliga tjänst

This Master?s thesis concerns the information behaviour of pastors in nonconformist churches (especially new evangelical and Baptist church communions) in Sweden in their spiritual service to the local parish. The thesis also looks into how the information flow functions in the pastors? context and why the information need appears as it does. The theory used in this study is contextual analysis based on Buckland?s, Weber?s and Patrick Wilson?s theories on authority and power structures.

Fjällfåglar : En jämförande studie från dal till topp i ett nordligt och sydligt svenskt fjäll

Title: Mountain birds ? a comparative study from valley to mountaintop in a northern and southern Swedish fjeld  Author: Kristian Zackrisson Abstract Main aim in this study was to increase the knowledge about birds in the Swedish mountain area. Three questions were asked: 1) Which bird species can be found during the breeding season along a low mountain slope from a forested valley to a mountaintop with bare mountain environment? 2) Do the number of species and individuals differ in different elevation zones? 3) Is the composition of bird species along a low mountain slope the same in the Kebnekaise mountains inLaplandand the Grövelsjön mountains in Dalarna? Bird census in two study sites located in the Kebnekaise mountains and the Grövelsjön mountains and subsequent analysis of the results from the bird census was the main parts in this study. Totally 20 bird species were found along a low mountain slope in the Kebnekaise mountains.

Upplevelse av fotfunktion : efter konservativt behandlad hälseneruptur

Background: Previously research shows that people treated conservatively can have reduced foot function after Achilles tendon rupture. However, there are few qualitative studies in the subject, so this essay is written to provide a deeper understanding of how these people feel about their foot function one to two years after the injury.Purpose: Investigate how people perceive their foot function after conservative treatment one to two year after Achilles tendon rupture and if they have an avoidance behavior in their everyday lives.Method: Four people who suffered from Achilles tendon rupture participated in this qualitative study. The study was conducted with semi-structured interviews, which in turn were processed using qualitative content analysis.Results: The perceived foot function is today varied in terms of mobility, strength and pain according to the participants. They feel difference in their everyday life in comparison with before the injury. It appears that participants have avoidance behavior when it comes to the situation of injury.

Kommunikation i dubbel bemärkelse : Enkätsstudie av barnfamiljer och SL:s digitala plattformar 

As a result of a successful human development around the world an extensive urbanization of societies are taking place that are networked in various ways. In these networks, increased travel and digitization are central where individuals and organizations converge in a constant and immediate wireless and mobile technology flow. An example of this is Stockholm and its public transportation company Storstockholms Lokaltrafik (SL). Although most participate in most of the network society, SL is struggling with an audience that seldom travel with them: families with children. We intended to find out how the communication of SL´s digital platforms could get families to travel more with public transportation.

Luftprovtagning samt analys av mono- och diisocyanater

When exposed to them, isocyanates can induce serious injuries in the respiratory tract and irritation on the skin and in the eyes. They are therefore interesting from the point of view of occupational health. The purpose of this thesis was to collect isocyanates in air with impinger-filter samplers and solvent free samplers. Furthermore the isocyanates were to be analyzed with liquid chromatography-mass spectrometry. The solvent free sampler consists of a polypropylene tube and filter holder fitted with glass fiber filters impregnated with derivatization reagent, coupled with a pump.
