Upplevelser och hanteringsstrategier hos ungdomar med IBD. : en litteraturstudie

The purpose of this study was to describe how adolescents aged 12-18 years with inflammatory bowel disease experience their illness and what coping strategies they use to manage their illness and improve their wellbeing. The method used was a descriptive literature study, and the result of the study included 15 scientific articles. Our results showed that IBD affected the adolescent?s everyday life and social life with friends, family and activities. The adolescents also reported that they experienced a feeling of vulnerability, altered body image and that they saw themselves as different from healthy subjects.

Finns det något samband mellan beröringsundvikande, självkänsla och kön?

Syftet med denna studie var att undersöka om attityden till beröring bland Växjö studenter harnågot samband med deras självkänsla och kön. Tidigare forskning av Fromme et al (1989)visade att personer med dålig självkänsla tenderar att inte kommunicera genom beröring,vilket personer med god självkänsla gör. Enkätundersökningen genomfördes på 186 studentervid Växjö universitet där enkäten var baserad på frågeformulären Tennessee Self ConceptScale och The Touch Avoidance Questionarie. Resultatet visade ett starkt negativt sambandmellan beröringsundvikande och självkänsla. Det visade även att män tenderar att undvikaberöring med andra män mer än vad kvinnor undviker beröring med andra kvinnor.

Lanczos potentialer i kosmologiska rumtider

We derive the equation linking the Weyl tensor with its Lanczos potential, called the Weyl-Lanczos equation, in 1+3 covariant formalism for perfect fluid Bianchi type I spacetime and find an explicit expression for a Lanczos potential of the Weyl tensor in these spacetimes. To achieve this, we first need to derive the covariant decomposition of the Lanczos potential in this formalism. We also study an example by Novello and Velloso and derive their Lanczos potential in shear-free, irrotational perfect fluid spacetimes from a particular ansatz in 1+3 covariant formalism. The existence of the Lanczos potential is in some ways analogous to the vector potential in electromagnetic theory. Therefore, we also derive the electromagnetic potential equation in 1+3 covariant formalism for a general spacetime.

Vad driver socialdemokraterna? - En fallstudie av motiven bakom århundradets skattereform

In 1988 the Swedish Social Democratic Party decided to reform the tax system. In this essay I analyse the motives behind their acting on a basis of the party strategic theories of Przeworski and Sjöblom. The reform commonly referred to as the tax reform of the century, was although they considered that it was a high risk project pursued together with the Liberal Party. The new tax system implicated a less progressive income tax scale, actions against tax avoidance and raised value-added tax. The empirical analysis is primarily based on memoirs written by the key actors.

Relation möter rationalitet: Om professionalisering av inköp av managementkonsulttjänster

The purchasing of management consulting services has traditionally been characterized by informal and relation based interaction. However, case studies have shown that there is a movement towards more formalized and structured purchasing procedures among buyers of management consulting services. The purpose of this study is to investigate the prevalence and the implications of this professionalization. To investigate to what extent certain mechanisms of professionalization have been implemented on the Swedish market, a survey directed to Sweden?s 500 largest companies was conducted.

Hastighetsstyrsystem för Förarrobot : Konstruktion, Modell, Test och Utvärdering

De krocktester som utförs idag är låsta till det system av styr och draganordningar som byggs upp. Att göra en krocktest därbilarna kan styras individuellt med hjälp av en förarrobot ökar friheten att designa tester. Att krocka två bilar som på bilden på framsidan, med 90 graders vinkel mellan bilarnas färdriktning ställer det mest tidskritiska kravet när de ska träffa varandra. Detta kräver en bra hastighetsreglering vilket är huvuddelen i examensarbetet.I denna rapport redovisas hur ett sådant styrsystem skulle kunna byggas samt tester i en simuleringsmodell för denna typ av krocktest.Simuleringsmodellen är uppbyggd i Matlab/Simulink och eftersträvar att efterlikna ett verkligt sidokollisionstest tillräckligt mycket för att kunna testa styrsystemet.Efter de tester som gjorts kan man konstatera att det är möjligt att konstruera ett sådant styrsystem som kan få två bilar att träffa varandra i en sådan sidokollision som är beskriven ovan..

Watashi wo aishite ? älska mig : En lacaninspirerad läsning av Haruki Murakamis Sputnik Sweetheart

A rhetorical analysis of the educational interactive film ?Riskprofilen?, produced by the Swedish Civil Contingencies Agency (Swedish: Myndigheten för Samhällsskydd och Beredskap). This essay uses the theories and methods of Procedural Rhetoric, as described by Professor Ian Bogost, and Visual Rhetoric, as described by Professor Brigitte Mral to analyse the interactive and visual component parts of the artefact, and compares them to the intended purposes of the artefact as stated by documents pertaining to its creation, found to be those of educating the public; marketing the agency; and driving traffic to its webpage. The artefact is through analysis found to fulfil the purposes of marketing the Agency and of likely increasing traffic to the website upon which it is hosted. Regarding the primary, educational purpose this analysis finds that the artefact does not teach a user the accident-avoidance strategies it claims to do, but is dependent upon further materials..

Beröringsfria avståndssensorer för en autonomgräsklippare

SammanfattningExamensarbetet har syftat till att undersöka möjligheten att utrusta Husqvarnas autonomagräsklippare med avståndssensorer. Dessa ska hindra gräsklipparen från att kollidera med hinder i sinomgivning. Gräsklipparen arbetar i en miljö där väder, temperatur, ljusförhållanden och underlagvarierar kraftigt. Detta innebär att kravet på sensorerna är högt.Av de sensorer som undersökts har det visat sig att ultraljud och ?structured light? är de system sombäst skulle kunna uppfylla all dessa krav till ett rimligt pris.I examensarbetet undersöks därför ultraljudssensorer från företaget Maxbotix närmare ochimplementeras i en prototyp.

Gotland ponies on extensive pastures ? a welfare assessment

Swedish farmers have the possibility to be subsidized by EU rural development programme for grazing animals on pastures to promote the biodiversity of flora and fauna. The environmental remedy sometimes does not allow supplementary feed and at the same time the Swedish Animal Welfare Act and the Swedish Agricultural Board?s regulations for animal welfare and protection states that animals, in this case horses, shall be fed with food of good quality and adapted for the species. The regulations also state that they should have an individual feeding regime that enables them to maintain a normal body condition. The aim with this master thesis has been to investigate if it is possible to keep Gotland ponies on extensive pastures, during late spring and summer and still maintain animal welfare. The horses were assessed every fourth week using a welfare assessment protocol developed in line with the Welfare Quality® project (submitted, Viksten et al) where physical, behavioural and resourcebased parameters were observed. Twelve one-year old stallions of the breed Gotland ponies purchased from different breeders were used in the study.

"Man har ju känt sig som en utomjording eller något sådant" : En kvalitativ studie om den subjektiva upplevelsen att leva med Aspergers syndrom

The purpose of this study was to elucidate how individuals diagnosed with Aspergers syndrome experience stigma as a result of their diagnosis. The paper was based on a qualitative method, consisting of six interviews with booth male and female participants. We took part of previous studies and research as well as existing theories on the subject, in addition to the analysis of our empirical material. Significant in this study was that all participants were relieved when getting the diagnosis, as they finally got an explanation for what was wrong. The results indicated that the majority of the informants felt worried of the possibility to experience stigma and discrimination, which resulted in that the majority of the participants tended to use an avoidance coping strategy.

Förändring som väckte känslor, när olika världar möts : en essä om samverkan i förskolan

This essay deals with the complexity that I perceive in the collaboration processes between preschool and parents. In the essay I present my interpretation of two self-perceived situations where my experience has been that the cooperation has not worked satisfactorily for either part. As a basis for my conclusions I use different theories and studies within the domain. My own experiences - both from ten years of working in preschool as well as from an eight-year experience of being a parent also comes into use. The purpose of my essay is to investigate how different horizons of understanding can come into collision, and how limitations in our own understanding of the perspectives of others can complicate collaboration between educators and parents.In the first story I discuss a situation where, in my professional role, I go into a conflict with a parent about how we have chosen to implement some changes.

Förluster av nedströmsvandrande fisk vid turbinpassage : En fallstudie för att främja den småskaliga, såsom storskaliga vattenkraften

The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.

Automatiserad inlärning av detaljer för igenkänning och robotplockning

Just how far is it possible to make learning of new parts for recognition and robot picking autonomous? This thesis initially gives the prerequisites for the steps in learning and calibration that are to be automated. Among these tasks are to select a suitable part model from numerous candidates with the help of a new part segmenter, as well as computing the spatial extent of this part, facilitating robotic collision handling. Other tasks are to analyze the part model in order to highlight correct and suitable edge segments for increasing pattern matching certainty, and to choose appropriate acceptance levels for pattern matching. Furthermore, tasks deal with simplifying camera calibration by analyzing the calibration pattern, as well as compensating for differences in perspective at great depth variations, by calculating the centre of perspective of the image.

Ohälsa hos polisen : en explorativ undersökning av riskfaktorer och dess påverkan på mental ohälsa

Earlier psychological research on stress and its complex of problems has identified several factors which have shown a relation with the occurrence of a poorer mental ill-health. In this study some of these factors have been examined in 69 police officers from Stockholm, Lund and Helsingborg. In the study, police officers with high and low self reported ill-health were compared considering trait anxiety, alexithymia and posttraumatic stress symptoms.The results showed that police officers with poorer mental ill health had a significant higher degree of trait anxiety, the dimension of alexithymia difficulty identifying feelings and the PTSD-dimension avoidance and hyperarousal. The results also showed several positive relations among the variables that divided the groups. On account of the last-mentioned the results will above all be discussed in an integrating perspective..
