Social fobi är en av de vanligaste ångestsjukdomarna. Rädsla och oro i sociala situationer och prestationsrelaterade dito är utmärkande för dessa individer. Social fobi tenderar, om den inte behandlas, att bli kronisk och det finns indikatorer på att tillståndet förvärras över tid. Idag finns behandlingar som ger goda utfall direkt efter avslut, men huruvida behandlingseffekterna håller i sig över längre tid är mer höljt i dunkel. Internetadministrerade självhjälpsbehandlingar har en möjlighet att öka tillgängligheten för denna klientgrupp och det är då av vikt att den är av god kvalitet.

The study emanates from the national quality registry for persons with severe and profound hearing impairment. The aim was to examine possible differences between signing deaf and adults with acquired severe hearing loss, with reference to self-assessed problems, how the hearing loss influences daily life.In total 234 adults aged 30-90 years were included (128 women, 106 men). In the registry, there are background variables and questions that the patients have answered. The results, indicated on a visual analogue scale (VAS) from 0-100, from a question ?To which extent does your hearing loss at present influence your life?? were analysed.The study was performed by pooling the results of VAS and dividing the patients into signing deaf and those with acquired severe hearing loss, and in age groups 30-60 and 61-90 years.

This study aims to investigate how small scale manufacturing companies reason around an implementation of a PLM-system, as well as the suitability of these systems compared to larger companies. The study is built on a qualitative method. Initially, secondary data was gathered through books, articles and reports. Primary data was gathered through four interviews. Two interviews were performed with PLM resellers, one interview was performed with a PLM developer, and one interview was performed with a small scale manufacturing company that opted to not implement a PLM-system.The results imply that overall differences between larger and smaller companies exist in regard to the need of PLM systems.

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

The Swedish energy system will be influenced by many future changes, such as energy and climate policy objectives. The installation of more renewable electricity could increase by using solar energy. Over the recent years, grid-connected photovoltaic (PV) systems have increased dramatically in Sweden, partly due to various support systems and compensation models. These support systems have been designed to make it easy for individuals and businesses to invest in self-generated electricity and thus contribute to the transformation of the energy system.The introduction of a higher proportion of solar energy may in turn affect the Swedish electricity system. This could mean that the electricity companies will be facing a number of changes in the near future.

The purpose of this Masters thesis has been to examine the importance of libraries for girls leisure time in secondary school. Focus has been on the use of the library as a leisure activity. Interviews were carried out with six girls of the ages 13 to 16. The conclusion of the study is that the library is of importance for the girls mostly through its books. Reading turned out to be an important leisure activity for the girls and the books provided by the library were of significance for their identity development.

24 years have passed since the Chernobyl accident when radionuclides were spread over largeareas of Europe, including the Scandinavian countries. Today, measurable activities of 137Csare still observed in many Swedish ecosystems.Ants (belonging to the order Hymenoptera) are social insects which collect organic materialfrom a large area around their nests. This study focuses on the 137Cs activity in ant nests andthe cesium accumulation in these nests. The aims were (1) to estimate the 137Cs fall-out in1986, (2) estimate the radiation exposure of ants and (3) find how 137Cs is distributed in an anthill. Seven ant hills (occupied by the species Formica polyctena) were studied near the villageof Hille, situated north of the city of Gävle in central Sweden.

Denna forskning handlar ett system som jag och min kollega Pierre Brockmanns skapade för att kunna visa för eleven hur han/hon ligget till i sina kurser som praktiseras ute i arbetslivet. Efter en inspektion från Skolverket uppdagades det att tydligheten på det gamla systemet inte var tillfredsställande. I studien har jag använt mig av kvalitativ studie för att få veta vad elever, handledare och yrkeslärare upplever att det fungerar.Tack vare djupintervjuerna fram kom förbättrings förslag vilket har lätt till att APU/APL- uppföljningssystemet har kunnat vidareutvecklas, och bli ännu tydligare. Även dokumentationen inne på skolan har utvecklats, för att tydliggöra för eleven ?vart den är på väg?.För handledarna har systemet betytt mer förståelse för att det är skola som eleven gör ute på sin praktik, och att medvetenhet om vad som skall läras på praktiken har gjorts tydligare.Yrkeslärarna känner sig mer professionella och att de har ett meningsfullt uppdrag när de är på APU/APL besök.

Today's research on animal assisted interventions (AAI) has focused on the positive effects on humans. Dogs used for AAI are an expanding market, but the research on this area hasn't followed the increasing use. The few studies on dogs in this field mostly observed their cortisol-levels and are very ambiguous. I have observed the behaviour of dogs working with AAI compared to when they are off-duty to see how they are affected by their work. Their handlers where also told to make an assessment of the dog's emotions during the session.

Psittacines and reptiles are exotic animals that are difficult to care for and it requires extra knowledge to make a correct assessment of their wellbeing. An animal welfare inspector, with an education in general animal welfare, may not have a deep enough knowledge of exotic animals to do a proper assessment of the animal?s general condition and its environment. In this paper it was therefore examined if animal welfare inspectors have enough knowledge to do a satisfying inspection of establishments working with selling of exotic animals. A literature study was used to examine difficulties with each species.

På dagens tjänstemarknad råder hård konkurrens. Inom bilservicebranschen har fokus tidigare endast varit på bilen men har nu skiftat till ett mer kundinriktat fokus. Bilservicebranschen har svårt att leverera vad som utlovas och flera oberoende tester visar på fusk under bilservicen, kunderna får därmed inte vad de betalar för. Det kombinerat med att bilarna blir mer tekniska och att kunder överlag saknar kompetens och har lite insyn i det arbete som utförs på verkstäderna skapar en problematik. Problematiken ligger i att bristen på transparens och kunskap gör det svårt för kunderna att bedöma om den utförda bilservicen är av hög kvalitet.

The aim of the present study was to investigate response time variations in tasks for assessment of high level language functions and how response time is related to education, age and gender. Response time is defined as the time to complete a task after it has been presented. 103 subjects, aged 20 to 80 years, were tested with the Assessment of Subtle Language Disorders, Sentence analysis and Morphological completion. The subtest Comprehension of ambiguous sentences showed the longest response time and Morphological completion the shortest. Correlations were found between increasing age and longer response time for Comprehension of metaphors and between education and response time for several subtests.

Vid skogskörning med traktor sitter föraren vänd framåt vid förflyttning och vänd bakåt vid lastning. Möjligheten finns för föraren att även förflytta traktorn sittandes vänd bakåt, men då måste traktorn vara köpt med den funktionen som tillval. Syftet med det här examensarbetet är att ta fram ett styrsystem som kan eftermonteras och som gör att traktorn kan styras av föraren även när denne sitter vänd bakåt. Två lösningar togs fram och gemensamt för de två är att ratten skall drivas av en motor som styrs av antingen en styrspak, miniratt eller strömbrytare. Den första lösningen går ut på att motorn och dess drivhjul går att fälla till eller från ratten beroende på om traktorn skall styras med ratten eller med styrspak, miniratt eller strömbrytare.

Knowledge organization is perceived as a central, constituting activity defining the notion of libraries. Critique calling for a new theoretical foundation voiced by active researchers within library and information science concerning the current knowledge organization has been utilized as a point of departure. Specifications concerning a new theoretical foundation implied by these critiques are considered within this thesis and theory found in The Order of Things by Michel Foucault proposed as an alternative theory for understanding knowledge organization as a human science where meaning, value and representation, by which the ordering of things is possible, is acknowledged as a result of human activity and history. Thus meaning, value and representation must be perceived as dynamic. An example of implementation of the proposed theory has been achieved by the use of bibliometrics.

Stress är i dagens samhälle ett vanligt förekommande fenomen inom många domäner där individer på olika vis drabbas. Högskolestuderande är en av grupperna. Tidigare forskning visar att olika faktorer bidrar till stress och att stress kan leda till allvarliga konsekvenser för individer. Studiens syfte var att undersöka vilka faktorer som relaterar till högskolestudenters upplevda stress. Till grund för studien låg fem frågeställningar.
