Automatisk bullerdosreglering i hörselskydd
På bullriga arbetsplatser använder personal ofta hörselskydd med inbyggda högtalare för att lyssna på exempelvis musik i underhållningssyfte. Om användaren lyssnar på höga ljudnivåer under långa perioder kan bullerskador uppstå i dennes öron. Enligt lagstiftning måste nivån därför begränsas i förebyggande syfte.Bullernivån är ett genomsnitt av de ljudnivåer användaren exponerats för under en arbetsdag. Användaren måste vila öronen om gränsvärdet för bullernivån nås.Om man utnyttjar att det är ett genomsnitt kan användaren tillåtas lyssna på en hög ljudnivå under en begränsad tid för att sedan sänka den. Det går att bevara både säkerheten och lyssningsupplevelsen om en sänkning införs långsamt.Detta arbete beskriver hur en algoritm till en digital signalprocessor kan konstrueras för att reglera ljudnivån.Målsättningen var att algoritmen skulle skydda användarens hörsel utan att försämra lyssningsupplevelsen, och utan att förbruka mer energi än nödvändigt.I algoritmen ingick en prediktor som predikterar mängden buller användaren riskerar att utsättas för, om denne fortsätter lyssna på samma nivå.Långsamma sänkningar av ljudnivån kan då utföras i tid innan gränsvärdet nås.Det visade sig att algoritmen endast behövde ett fåtal samplingar per sekund för att skatta och reglera ljudnivån tillräckligt precist, vilket reducerade energiförbrukningen.Resultatet visar möjligheten att kombinera målen för säkerhet, lyssningsupplevelse och energieffektivitet i hörselskydd.Algoritmen implementerades inte på ett skarpt system.Den hade enbart tillgång till ljudsignalen användaren ämnade lyssna på i underhållningssyfte..

Vad ha?ller da?ren vaken om na?tterna? : utforskande av det ogripbara
The Swedish social insurance agency provides financial support for families and children, but also for people with work injury, illness and at old age. During 2012 they saw the amount of notifications of insurance increasing in Sweden, which is a development that cost our society a great deal of money. With the aim to pursue a sustainable development I have therefore devoted this project to wellness and stress management within preschool.The employees of preschool are often dealing with a lot of stress, due to the big groups of children that causes high noise and sound levels. The high noise and sound levels is a contributor to stress which additionally can damage the health and cause impaired hearing loss. About half of the people around their forties until the age of retirement have difficulties understanding speech in large groups.The purpose of this project has been to investigate the causes of negative stress for my target group, women between 30-60 years old who works in preschool.

Rutiner och regler kring instegsarbete : En studie gjord för att undersöka vilka regler och rutiner som finns kring instegsjobb för nyanlända, hur dessa följs och eventuella förbättringsåtgärder.
This essay illustrates the rules and procedures when it comes to inclusive labor markets. In Sweden we have a labor market program called entry-level jobs, which makes it easier for immigrants to get work since our public employment agency pay remuneration to the employers.In this essay I am answering the following questions:How does the work of our public employment agency and trade union looks like before, during and after an employee has gotten a subsidized employment called entry-level job, and in which way can this work be improved if necessary?How extensive do entry-level jobs contribute to increased integration and establishment on the labor market for newly arrived immigrants?How does the Swedish measure on entry-level jobs approach within the scope of European regulations about measures for inclusive labor market?To find answers to my questions I have used social science methodology and juridical method. I have performed document studies and interviews with concerned parts.The conclusion of above subordinated questions is that we need to extend the Swedish laws covering entry-level jobs so that the concerned parts know which assignments they will be responsible for when problems emerge on a workplace.When it comes to if entry-level jobs contribute to increase integration and establishment on the labor market it seems to be more important to integrate the immigrants quickly, and with which quality it is made does not seems to matter. The public employment agency has to emphasize the importance of Swedish language so that the employees can be independent from authorities in the future.

McDonald'sofferings and customers' bounded rationality results in that customers are satisfied with an"ok" experience, which adds to their low expectations of McDonalds. This makes clear thatMcDonald's does not have to make an effort through constant adaptation at the local level toachieve a "great" level of satisfaction.
"Nobody never gets to heaven, and nobody gets no land" : En nivåstudie av produktion, struktur, ensamhet och begär i John Steinbecks Of Mice and Men
My main purpose with this paper of John Steinbecks Of mice and men is to both analyze the long-lived structures and the unique individual destinies of the novel. I employ the method of the historical Annales-movement and use three divided levels in my analysis to try to capture these high structures and low moments of humanity in Structure, Konjuncture and the Individuality. The first level, Structure, is used to see how long-lived almost invisible geographic structures set the human act of condition. The second level, Konjuncture, is easier to grasp in understanding of time and embraces for example economic structures as the industrialism. The last level of Individuality is the fastest in time and easiest to understand but in the long run also the least important.
Att identifiera sig med en organisation : En studie om Posten Örebros organisationskultur
The purpose with this study is to identify an organizational culture at Posten Örebro based on Edgar H. Schein´s theory about the three levels of culture. These three levels consist of artifacts, espoused beliefs and values and basic underlying assumptions. Artifacts represent the visible and tangible of an organization and this level is the easiest level to identify. Espoused beliefs and values include common thoughts and ideals within the organization and are an aware, but not necessarily material, cultural level.

"Och vilka ska förändra näringslivet om inte kvinnorna?": En studie av fyra kvinnliga entreprenörer som arbetar med förändringsarbete
Sweden is described as one of the most forward-thinking countries in the world when it comes to equal opportunities, yet still management is being dominated by men. Looking at entrepreneurship and gender, the author has written four herstories about female entrepreneurs working, through enterprise, to bring about change to the male domination of top level management. The primary purpose of this master's thesis has been to look at theories on entrepreneurship/ management and gender to analyse how the entrepreneurs relate to their roles as [i] entrepreneurs, [ii] agents of change, and [iii] women. The findings show that they attach particular emphasis to their roles as entrepreneurs. As regards the work for change, being female is described as both advantageous and irrelevant, or insufficient.

The aim of our study was to examine how the elderly experience their meal situation in a sheltered housing. We have used a qualitative approach. We conducted individual interviews with six elderly in a sheltered housing to collect our empirical material. To reach the purpose of this study we tried to answer the questions: which factors affect the elderly person?s experience of the meal and which significance does the meal have for the elderly? To reach deeper understanding for our collected material we used Maslow?s theory of human motivation, the two concepts of Tönnies; gemeinschaft and gesellschaft, disengagement theory and the concept of Bourdieu, called habitus.

This essay examines middle school students? understanding of a text read aloud to them in English and the connection between the degree of listening comprehension and the expected increase of vocabulary throughout middle school. The same listening comprehension test was carried out in grades 4, 5 and 6 in a middle school in order to survey differences in English listening comprehension in regard to the ability to reproduce the content of an oral text. The result shows that there was a progression from level to level when it comes to comprehension and the number of words reproduced and that this progression was most noticeable between grades 4 and 5..
