Att styra säkerhet med siffror : En essä om (att se) gränser

Work, especially that in complex, dynamic workplaces, often requires subtle, local judgment with regard to timing of subtasks, relevance, importance, prioritization and so forth. Still, people in Nuclear Industry seem to think safety results from people just following procedures. In the wake of failure it can be tempting to introduce new procedures and an even stricter "rule following culture". None, or at least very little, attention is given to tacit knowledge and individual skills. I am aiming to highlight the inadequacy of putting too much trust in formalization and that reporting and trending of events will contribute to increased learning, an increased nuclear safety and an efficient operational experience.

Kognitionsforskning i djurhållningen: grisars kognition och dess tillämpning vid slaktsvinshållning

Pigs are often mentioned as relatively intelligent animals when compared to other nonhuman species. Despite this knowledge, the vast majority of pigs are kept under conditions that lack opportunities to satisfy their cognitive needs. Therefore, a need to evaluate the present scientific studies about pig cognition was acknowledged, in order to evaluate to what extent the knowledge is applied in the husbandry of finishing pigs. If a considerable lack of application was determined, suggestions about how to use the obtained information to improve pig welfare were also to be made. A synthesis of the present literature was made, and it could be concluded that a considerable amount of studies had been carried out in the present area. The pigs of today appear to have the same behavioural and cognitive needs as their ancestor, the wild boar.

Kronisk smärta - En litteraturstudie om patienters upplevelser och tankar om sitt dagliga liv.

The purpose of this litterature review is to illustrate the nursing care to patient with chronic pain. As a theoretic frame for this study we choose Aron Antonowsky. The results of this study are based on 8 scientific articles. The findings are presented in main categories and ideas. The findings show that chronic pain is a multidimensional phenomenon that influences peoples quality of life in a physical, psychological as well as social way.

Portrayal of animal communication in wildlife documentary

Many people turn to documentaries for knowledge about animals, but do documentaries give us a truthful portrayal of animals and their behavior? This study looks at how the communication behavior of the portrayed animals is depicted in three episodes of The Life of Mammals. These episodes were observed after which the contents were compared to scientific literature on the same topics. The results show that quite little communication is actually shown in the episodes about plant predators and meat eaters and relatively much of it is shown in the episode named Social Climbers, involving primates. The matching literature suggests that based on the narrative and the accompanying footage, the viewer is getting a realistic picture, with the exception of a few questionable cases..

Varför Klass? Att studera ojämlikhet ur ett statsvetenskapligt perspektiv

This thesis contains a wider discussion on the analytical framework of classstudies in political science. The purpose is to put class into the light of a usefulmethodological and theoretical tool when it comes to studies on inequality and political,as well as scientific approaches and explanations to why people have awide range of differences in how they pursue their lives. It is my ambition to discusshow class relations can be theorized and explained within a given context, aswell as in society as a whole. I see the complexity of this field as a resource to enhancethe epistemological as well as the empirical discussions within the politicalscience scholars..

"De står tillsammans och försöker förstå det ofattbara" : Medierade sorgeyttringar i svensk nyhetsjournalistik

The aim of this Master thesis was to examine news journalism covering expressions of mourning related to violent or unexpected deaths. What rituals for mourning are brought out in media and do media present guidance to how mourners should behave? The questions examined were: What characterised news events that leaded to texts on expressions of mourning? How was grief framed? Which narrative patterns were there in the texts? How was the deceased represented? How were the mourners represented? 165 texts, from Swedish daily newspapers, covering 93 different news events were analysed. The methods were mainly discourse analysis with focus on identities and relations, but also semiotic analysis with focus on staging and symbols and narrative analysis with focus on patterns for storytelling. The result showed that a news story about ordinary people expressing their feelings of grief has elements of melodrama. The news story is based on the myth of the victim, and formed as a typical story where equilibrium is disturbed when the inconceivable happens and the mourners can by their actions restore equilibrium.

Bibliotekariers syn på Open access : Enkätundersökning bland bibliotek med inriktning teknik, naturvetenskap, medicin och farmaci

Open access to scientific literature on Internet is a concept which is supposed to change librarians' work. The aim of the thesis was to examine librarians' perception of Open access. A questionnaire survey was conducted among librarians at libraries with specialisation in technique, natural sciences, medicine and pharmacy in Sweden. Even though Open access can be regarded as an alarming for librarians' work, the results of the survey showed that the future of the librarians' profession can be positive if they flexibly adopt their work routines according to changes in publication forms and library users' needs..

Utformning av ett materialflödessystem anpassat för HSP-Gripens produktion

Like many small-time companies there is a need to improve the flow of materials at HSP-Gripen AB. The company develops and manufactures hydraulic-powered grapples for the machine- and forest industry. By mapping the material flow in the current production and gathering necessary data, suggestions on how different parts of the production could be controlled is presented in this dissertation. This has been achieved by the study of relevant scientific literature. The suggested ways of controlling the production consist of 2-bin systems, hybrid material flow system as well as a cyclic product-planning.

E-handel : Vilka faktorer styr konsumentens köp över Internet och då med fokus på hälsokostbranschen?

In today?s IT-community, consumers use the internet in a increasing rate to find information or to purchase products and services. This has led to a growth in the market, but also a greater competition between e-stores and web shops. To separate yourself from the masses has become more important, the question is; what strategy should the IT-salesman use? The meaning of this scientific study is to find and focus on witch the primary factors/aspects are, that controls and is the very foundation for the consumer making a purchase, by using the internet.

Evidens som hegemonisk strategi i socialt arbete : en diskursanalys av den språkliga praktiken i en barn och ungdomsgrupp som arbetar med ett strukturerat beslutsstöd

This thesis describes how social work language practice circulates around the implementation process of an evidence based structured assessment tool – Savry. The purpose is to examine and understand the social workers language practice in a working group that uses this structured assessment tool in their work with youth. The purpose is also to look for dimensions of identity in terms of discourse. The ontological viewpoint is post-structuralism where language is in focus. The theoretical framework is discourse theory based upon the work of Ernesto Laclau and Chantal Mouffe.

Bestämning av lägsta luminans för utrymningsskyltar

This report is based upon an experimental study of exit sign luminescence in different environments. The purpose is to evaluate the lowest luminescence of an exit sign, based upon Swedish regulations. Scientific experiments have been conducted in a controlled environment, where exit sign luminescence was graded by an evaluation group. The results of these have been verified by similar experiments that took place in two department stores. The final result of the study is guidelines for appropriate exit sign luminescence in different environments..

Miljökommunikation i dagspressen : En diskursanalys av hur SvD och DN framställer miljöfrågor

The starting point of this study is that the news media in general strongly influence which topics determine the public agenda by their choice of what is considered newsworthy. The study is based on articles from two major Swedish daily newspapers, Svenska Dagbladet and Dagens Nyheter. The aim of our thesis is to establish how the environmental public debate as portrayed in the newspaper corresponds to the environmental discussion within the scientific (subject matter expert) field, that is taught by the academic institutions, or if the two materially differ. The environmental communication discourse at the academic institutions advocates ?episodic? formation as the driving force behind transformation of attitudes and behavioral preconceptions. This episodic formation is aimed at incentivizing change by creating intimacy to the incident by linking cause and consequence to the individual citizen instead of to society as a whole.

Anhöriga i sorg. Sjuksköterskans stödjande roll till anhöriga i sorg.

Death is the only experience we know we will come across in our lives. Yet it is so difficult to speak about death and the sorrow before and after death occurs. The aim of this literature study was to find out how as a general nurse one can help relatives to handle their situation in mourning. The question was: How does the nurse feel when confronted with mourning relatives? What measures and caring should the nurse take to alleviate the handling of the relatives in mourning? After scrutiny and critical analysis of ten scientific papers, some common denominators have remained.

There after onearticle was excluded because of very low quality of the study.

Hållbarhetslivscykelanalys på kakel och klinker : Analys av vägen från vagga till grav ur ett hållbarhetsperspektiv

In this report two Sustainability Life Cycle Assessments are carried out for two types of tiles for Riksbyggen, to contribute to a sustainable urban transition. Sustainability Life Cycle Assessment involves performing a life cycle assessment based on four principles based on scientific research and presented by the non- governmental, non-profit organization, The Natural Step. The principles concern raw materials, chemically produced substances, degeneration of nature and social conditions.Origin of products, manufacturing sites and manufacturing procedures were initially completely unknown and much of the work has consisted of finding the entire cycles, understand manufacturing processes of ceramic tiles and evaluating what materials and what type of energy sources that are required for the production. A socially sustainable perspective has been of high relevance alongside an ecologically sustainable perspective.The report begins with the basic underlying facts and the purposes of this investigation and that the reasons why Sustainability Life Cycle Assessments are carried out are to provide Riksbyggen and the own workers with documents presenting Riksbyggens ideas regarding sustainability and to hopefully get the ideas further down in the supply chain. The methods used to fulfill the investigation are presented and scientific facts about LCA and ceramic building materials are reviewed.
