"Man kan ju inte gå runt och va rädd varje dag" : hur människor upplever och hanterar klientrelaterat hot och våld i arbetet
Syftet med studien var att undersöka hur människor upplever och hanterar risken att bli utsatt för hot och våld från klienter i arbetet. En kvalitativ ansats valdes vilket innebär att fokus har lagts på subjektiva upplevelser och erfarenheter av studieområdet. Studien genomfördes gentemot Socialtjänsten från två kommuner och urvalet bestod av intervjuer med elva socialsekreterare vars arbete innehåller myndighetsutövning och kontakt med klienter. Analys av data gjordes enligt induktiv tematisk analys. Resultaten visade att det föreligger en risk att bli utsatt för hot och våld av klienter men den upplevs vara liten.
Design av försöksanläggning för trycksatt rökgasrening vid oxy-fuelförbränning
Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.
Hållbar utveckling i värdekedjan
Detta är ett examensarbete inom textil produktutveckling som har sin grund hos uppdragsgivaren Bellaobastian. Syftet med rapporten är att ge en inblick i miljöarbetet i värdekedjan hos mindre konfektionsföretag, vilka svårigheter som kan förekomma och hur den hållbara utvecklingen kan effektiviseras. Vi vill ge mindre svenska konfektionsföretag råd och förslag om hur de kan uppnå en tillfredställande nivå på deras miljöarbete utan tillgång till enorma resurser.Vi har utfört intervjuer, litteraturstudier samt jämförelseanalyser mellan företagen H&M, ACNE och Lindex. Vid diskussion och analysarbetet var det tydligt att miljöarbete i värdekedjan är en komplex process och att det är flera aspekter som spelar in.Vi har kunnat identifiera åtgärder som företagen kan utföra i hopp om att uppnå en mer hållbar utveckling, både specifika som tex, materialval men även mer övergripande som att ändra sitt synsätt. Åtgärderna vi kunde påvisa kretsar kring:- Minska överkonsumtion och effektivisera resurssparandet- Minska koldioxidutsläppen- Använd miljöledningssystem och märkningar- Ändra företagets synsättEn av slutsatserna vi kunnat konstatera genom våra undersökningar är att det inte räcker med att åtgärda problemen.
Har elever något inflytande över samhällskunskapsundervisningen? : Skulle elever i årskurs 9 vilja ha mer inflytande över samhällskunskapsundervisningen?Anser elever i årskurs 9 att de har inflytande över samhällskunskapsundervisningen?
The objective of this paper is to describe and analyze female irregular immigrants and their experience of how relationships with other people affect their lives and identity.A qualitative method is used in the study, because my main purpose is to analyse the respondents? lives and life experiences. The analysis is based on a symbolic interactionism perspective. The results are also analyzed based on previous research and the concepts underlying the paper; irregular immigrants, discrimination, power and identity.In summary, the respondents have a clear picture of how they live and experience their relationship to others and themselves and how this affects their lives and identity.Their experiences affect their lives and influence their behaviour and identity when they interact with others. Their own view of their situation means that they are afraid to seek care or report sexual abuse, threats or other similar conditions.
En studie av miljöfaktorers betydelse för förekomsten av Francisella
This thesis aims to analyse relations between the risk of Francisella in endemic areas and environmental variables. The thesis also discusses relations between occurrences of Tularemia and meteorological factors. The analysis resulted in several significant models that explained the occurrence of Francisella. These models can however only be applied to the year 2004 since there were too few test performed the other years, therefore no comparisons could be made. Another conclusion was that the relative humidity was significally higher in the year 2003, the same year as the occurrences of Tularemia was at its peak. .
Sustainable shopping : consumer behavior in purchasing and donating secondhand clothes
Textiles are made in an unsustainable way and there is a need to find alternative ways and material to reduce the negative impacts on the environment, humans and animals. Problems like pollution, excessive water consumption and loss of soil fertility is a result of this lack of diversity. It is a necessity to find innovative alternatives in other fabrics due to the unsustainable use of cotton and polyester fibers. As in many other countries in the Western part of the world, in Sweden there is a rapid turnover and increased selling of clothes that result in increased textile waste. About 15 kilogram of textiles (net inflow) is consumed per person each year.
Some people get it. Others are assholes. Kontradiskurs, subversiv potential, hegemonisk makt och performativ marginalitet utifrån tre nivåer av skräpkultur.
Sustainability work is something that is emphasized more and more. Corporate Social Responsibility, CSR, is discussed and the question of how much responsibility companies should really take is frequently in the news. Companies tend to ask themselves how much responsibility they should take. CSR is a common concept of companies environmental and social work and a concept we tend to see here and there in our modern society. CSR includes companies? social responsibilities, both in terms of carbon footprint, working conditions, social responsibility and more.
Anledningar till staters anskaffande och behållande av kärnvapen och faktorer som påverkar staters kärnvapenpolitik
The purpose of this thesis is to explain why states obtain nuclear weapons and the role variousactors and interests play in the making of states´ nuclear policies. The main questions are asfollows: (1) What big theories exist concerning states obtaining nuclear weapon and nucleararmament in International Relations and what relevance do they have of the post cold-war period?,(2) What is the meaning of the perspective of the Military-Industrial Complex (MIC)?, and (3)Arethere empirical studies which supports the existence of a MIC in the United States?The focus lies on actors and driving forces that are internal to states and it is also important toinvestigate if the theories have relevance for the post 9/11-era. The study uses the method ofqualitative literature-study with some quantitative segments. It is claimed that states might beinterested in justifying their behaviour in a morally appealing way and that real reasons may behidden.
Högtempererat borrhålslager för fjärrvärme
The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and economic viability in Gothenburg, Sweden, a city with access to high quantities of waste heat.The concept has proven potentially environmentally friendly and potentially profitable if its design is balanced to achieve a good enough supply temperature from the HT-BTES. The size of the heat storage, the distance between boreholes and low borehole thermal resistance are key parameters to achieve high temperature. Profitability increases if a location with lower temperature demand, as well as risk of future shortage of supply, can be met.
Utomhuspedagogik i skolan
Nature is in many ways considered a source to both physical and mental health among people. Trends in today?s society reveal that children become more distanced to nature. Seen from the perspective of sustainable development this trend is considered crucial: it is of importance that children in their early ages experience nature positively in order to develop a dedication towards environmental issues as adults.The purpose of this study is to investigate how teachers use outdoor learning as an educational tool. Research data were collected through a series of interviews.
Miljö- och hälsorisker med konstgräsplaner
In Sweden today many municipalities and sport clubs chooses to build artificial turfs becauseof the increased period of using the turfs during the year and less maintenance requirementsthan for natural grass fields. What could be problematic with artificial turfs is the rubbergranules used as infill material in the turf matt. The rubber granules are often made fromrecycled tires, which may contain for the human health and the environment, harmful substances.This was the reason why the Swedish Chemicals Agency commissioned a statusreport in 2006 which, among other things, concluded that the environmental and health risksassociated with granules made from recycled tiers in artificial turf fields were small, but thatthere could be a local environmental hazard. The purpose and objective of the risk assessmentwas to identify how artificial turf plans granules can affect recipients in the area closeto the pitches and provide input to reduce the spread of metals and substances harmful forboth human health and the surrounding environment. The work was divided into three parts:(1) the construction of artificial turf pitches and their material content, the spread of granulatesoutside the fields and disposal of artificial turf pitches.

Humanitära interventioner. Europeiskt handlingsutrymme i förhållande till ett modernt interventionsbegrepp
The world is getting smaller. Global markets, political processes and communication technology bring people together. Even though many of these processes are dynamic and constructive, they have also resulted in a need for better and more effective ways of international conflict resolution.
This thesis investigates central issues connected to the concept of humanitarian interventions in relation to current and future legislation of the European Union. The overall question is whether the rapid globalization process has resulted in a change of international law towards more liberal view where authorization of the security council is not always needed? And, if there has actually been such a liberalization, how does that affect the legal possibilities for the European Union to carry out armed operations without the consent of the global community?
The conclusion of the thesis is that international law has been modified mainly in two aspects: First, the concept of sovereignty is no longer seen merely as a right of the nation, but also as a responsibility.
Säkerhetsutvärdering certifikatserver i stället för aktiva kort
Business and organizations use computer network in a greater extension than ever before, especially for business-critical use. That increase the demand of security for all systems, both against internal and external threats. The demand on the authentication method used today increases. Today they normally uses password or some kind of smart card. I will performa literature study that will investigate the possibility to increase the security in authentication of users without the use of extra hardware.
Teknikimplementering vid muddringsprojekt : Viktiga faktorer vid teknikval samt olika aktörers betydelse i processen
There are today large amounts of contaminated sediments in the Baltic Sea. These contaminants are the result of many years industrial activity where the contaminants have not been taken care of and just released out in the water. When ports want to dredge in their fairways and harbor areas the contaminated sediments need to be considered since they are a environmental risk. The development in this area has been slow and new techniques have just recently made its way into dredging operations in the Baltic Sea region. As a result of this there are no clear methods for implementing new techniques today.
