Att arbeta med ständig osäkerhet : En studie av High Reliability Organization
There are certain organizations that manage to handle risk in such a successful way that they almost stay error-free, in spite of the fact that they daily face the risks of accidents. These organizations are usually given the name High Reliability Organizations (HRO). While the most common example is that of a nuclear plant the variety of what organizations can fit into the category is extensive.The purpose of this study is to describe safety culture and theories about HRO and how these can be found in practise within an organization.This qualitative research uses influences of ethnography in its method. The ethnographical approach was picked due to the field of the study and the cultural context in which it is set.The results of the study identify a number of elements sorted into four themes. These themes are deemed compatible or non-compatible with relevant existing theories.
Ungdomars säkerhet på Internet : Uppfattade risker och ansvarsbördan
The purpose of this paper has been to explore how Internet is perceived, with reference to youth, risk and responsibility, by a section of the population in North-West Skåne in Sweden. The questions central to our area of interest were:- Where does the responsibility for a safe Internet environment lie?- What measures are believed to be able to make Internet safer?- Are the opinions about safety on the Internet affected by an individual'sknowledge and experience of the Internet?- Is there an awareness of which institutions are involved in Internet safety?We compared the results of our survey with earlier surveys done by SAFT and Eurobarometern. Additionally we compared various categories such as gender and age to discover any patterns within the groups.There is a clear conflict in the answers given by the group we studied, between the desire to have access to all the information and experiences Internet has to offer and the desire to protect youth from inappropriate content and/or influences from unknown sources. While we did find concern regarding issues of safety we did not find any indication of "moral panic"..
Erosion vid dagvattendammar : litteraturstudie med inventering av 13 dagvattendammar
Vatten har alltid haft en stark dragningskraft på människan. De flesta uppfattar vatten som avkopplande och rogivande. I alla tider har dammar, fontäner och vattendrag utgjort en väsentlig del av landskapsarkitekturen. I våra dagar utgör dagvattendammarna ett tillskott i vår miljö, där syftet i första hand är att fördröja dagvatten. Denna funktion kombineras i många fall av önskan om att skapa rekreativa våtmarksområden som kan utgöra ett positivt inslag, särskilt i urban eller halvurban miljö, där tillgången till naturen saknas.
Dental erosion : kolsyrade vattens erosiva potential
Syftet med studien var att undersöka den erosiva potentialen av vanligt förekommande kolsyrade vatten med eller utan smaksättning. Studien genomfördes som en laboratoriestudie vid Institutionen för Odontologi vid Göteborgs universitet. Totalt omfattades studien av 34 buteljerade kolsyrade vatten med eller utan smak, tre kolsyrade vatten producerade i kolsyreapparat samt sex referensdrycker. Samtliga produkter testades genom registrering av initialt pH med pH-elektrod och buffring med 0,1 M NaOH till det värde då pH neutraliserats. Dryckens surhetsgrad beräknades därefter vilket anses som ett mått på dess erosiva potential.
Utökat ballistiskt skydd mot finkalibriga projektiler på ytstridsfartyg
Detta arbete handlar om med vilka material som det ballistiska skyddet mot finkalibriga projektiler kan förbättras på befintliga svenska ytstridsfartyg. Eftersom det befintliga fartygets konstruktion i sig innehar en viss skyddsförmåga (grundskydd) behöver denna inledningsvis beskrivas för att definiera utgångspunkt.Att förbättra skyddsförmågan genom att komplettera den redan befintliga konstruktionen med tilläggsskydd innebär att fartyg får helt förändrade förutsättningar att klara av nya hot och uppgifter och därmed också få en förbättrad livslängd.Genom att studera för- och nackdelar hos olika tekniska lösningar framkommer vilka som är realistiska.Fartyg kommer sannolikt att utrustas med olika material eftersom ytor- och utrymmen kommer att behöva prioriteras. Olika materialval kommer också att styras av kompromisser mellan ballistiskt skydd och lastbärande konstruktioner..
Biotopskydd av stenmurar : Skäl för dispens
Stone walls in agricultural land are incorporated in the general protection of biotopes. They are protected because they provide a habitat for endangered species. Therefore it is illegal to carry out proceedings in an area that is included in the protection of biotopes. In order to do that, exemption is needed which can only be granted if there are special reasons. The essay stipulates what these special reasons are.In an exemption errand the interest for nature conservation must be weighed against a public or a private interest.
Doing Business in China - A Best-practice Model for Foreign Invested Small and Medium-sized Enterprises (SMEs)
Foreign invested SMEs have recently become increasingly interested in China. The enterprises are in this report categorized as second wave companies since they follow the footsteps of previous pioneers, of which mostly were larger companies. The ambitions of the SMEs are either to sell products on the ever expanding Chinese market or to utilize the potential of low cost production for global markets. The existing literature is fragmented and solely based on the experience of larger companies. We believe that SMEs are facing new and different challenges, and thus a new generic theoretical frame work is desirable.
Integration av systematiskt brandskyddsarbete med ISO 14001
As a result of the Civil Protection Act, there is an imperative for Systematic Fire Preventive Measures, SFPM. SFPM can be divided in two parts: organisational preventive measures, and documentation of fire preventive measures. The manner in which SFPM is to be conducted is similar to that of the environmental management system ISO 14001. This report provides suggestions how to integrate SFPM with ISO 14001..
Turordningsreglerna - snart ett obsolet arv?
Sweden's contribution to the world today is not labor-intensive industry, it is high technology and know-how. Many of the rules concerning employment security for the workers derived from the industrial era and have been to some extent modified by hand. This paper focuses on the discrepancy between the purpose of the priority rules in Swedish law and how it works in the reality. My opinion is that due to the development of the labor market, a powerful revision of priority rules is needed. In addition to today's job market is knowledge-intensive I point in the paper at a number of factors that contributed to the loosening of the priority rules. Examples of these are the increased incidence of temporary staffing, more open markets and more multinational companies, political will to disadvantaged groups in the labor market should be prepared job and gender issues.
Seroprevalence of Japanese encephalitis virus in pigs and dogs in the Mekong Delta
Japanese encephalitis virus (JEV) is one of the leading causes of acute encephalitis in humans. The virus is spread by mosquitoes, mainly belonging to the Culex species. The main reservoirs are considered to be birds and pigs, with pigs constituting the most important reservoir in regard to human infection. During the last few decades the production of pork has increased significantly in Vietnam. With 90% of pigs being kept in households owning 10 pigs or less, pigs are widely spread across most parts of the country.

This Projects goal was to develop a manual, which was to be used as help for a fishing company in the making of an SMS (Safety Management System). The manual was going to follow the guidelines presented by the IMO (International Maritime Organisation) and the Swedish Transport Agency. The projects client was a smaller fishing company that was about to build a fishing vessel.The work has been carried out as a project, it was finished within the schedule and the client was most satisfied with the result. The client has used the manual in the making of the Safety Booklet (SMS) and they are now certified according to the rules of the Swedish Transport Agency..
Optimering av OTEC-system
Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.

Inventering och riskanalys av skolskjutshållplatser : kvalitetsäkring med avseende på trafiksäkerhet
In Trollhättan municipality approximately 700 school bus stops are in service. To ensure high quality of the performance of school bus operations, with focus on traffic safety, it was decided to conduct a survey of bus stops including assessments of risks.This master thesis aims to identify the factors affecting road safety at bus stops and pedestrian connections, and to conduct an inventory and analysis of selected sites in Trollhättan municipality. The work also aims to show examples of how risk assessment should be performed in future studies. A risk analysis model provided by the Swedish Transport Administration is supplemented and used in a field study. The risk assessment is based on, inter alia, traffic flow, visibility distance, lighting, speed of traffic and the presence of bus shelter.
Hållbart jordbruk inom vattenskyddsområde : En studie om Sverige, Danmark, Frankrike och Tyskland
To guarantee protection of our drinking water, water catchment protections are established. These are divided into three different zones and in the first zone it is most likely that an activity, such as agriculture, will contaminate the water resource. Hence the activities are strongly regulated or banned. The EU communion is working towards a sustained water quality through several directives; Nitrate Directive, Waterframwork directives and Sustainable use of pesticide directive. The main purpose is to regulate the diffuse pollution from agriculture.This thesis is about how Denmark, Germany and France are working towards a sustainable agriculture within water protection areas.
