Anställningsotrygghetens effekt på självskattad hälsa, i hög respektive lågkonjunktur
The subject of this study was to research whether or not the effect of job insecurity on self reported health differs between good and bad times in the economic climate. Two different years of a national health survey from the Swedish institute of health (FHI) served as data, with 2007 representing good economic climate and 2009 doing the opposite. Both years consisted of data from a national health survey distributed to 20 000 random individuals in Sweden, where 2007 had 5738 valid cases and 2009 had 10 373. A quantitative method was used to determine the difference, consisting of a three variable cross tabulation with chi2-analysis as well as a model of binary logistic regression for each of the two years.The cross tabulation found a significant difference between the two years, with those reporting job insecurity having less of a chance to report bad health during the year representing bad economic climate. While the logistic regression showed the same tendency, the two years could not be significantly differed from each other in that part of the analyzes.With this in mind, the conclusion from the whole test was that no significant difference could be found between the years regarding the health effect of job insecurity..
Utveckling av en ny tillverkningslina
This report contains results of our study at CTC in Ljungby. CTC produces heating products such as boilers, heat pumps and additional products to their heating systems.The purpose of the report is to make a proposal how CTC will supply their new production line for heat pumps with materials. The proposal includes a production layout and a scheme for how to place the material in the production storage.The new production line will produce two different products and both of them have several variants. The line will also have a mixed flow, so the products can be produced in a random order. These conditions demand that the production line has great flexibility and that the material to all the variants can be stored in the production storage.With these conditions as input we made a layout proposal to the company.
Self-organizing maps ? en atlas över informationsrymden
The purpose of this thesis is to examine how semantic relations in a document collection can be visualized with a Kohonen self-organizing map. It can be seen as a map of the information space which can be used to support information retrieval. The study makes a comparison of the possible differences between a map that is based on morphologically unprocessed text and a map where the text has been lemmatized. The text that is being processed is the definitions of all the existing instances in WordNet of a random selection of indexing terms from the Times-collection. The purpose is to see if morphological processing somehow can show different semantic connections between term instances based on their definitions.
Användarcentrerad design för att förbättra rapporter i kvalitetsregister
In modern health care, the quality registry is anexcellent tool to monitor everyday work. Collected data forms a foundation, presented as online reports, from which local work efforts to refine care quality can be performed. All reports are coded manually by specially trained developers. This is a tedious process and hence becomes a bottleneck in the strive for improvement.This thesis evaluates whether an extended way of dealing with reports can fit into the existing work situation, with main focus on the idea of creating custom reports directly within a quality registry. It provides a set of conclusions regarding today's usage of reports as well as the users' general and specific needs within the area.
Referenstaktiker : högskolebibliotekariers sätt att överbrygga kommunikativa gap
The aim of this master thesis is to study how academic librarians can overcome the gap between themselves and the user. The gap, as we see it, is generated by the user's deeper knowledge surrounding her subject in comparison to the librarian. This knowledge gives the user possibilities to handle certain discourses attached to the subject and a knowledge how sub-subjects relate to each other within the main subject. At the same time the user is in need of help to find information within her subject, this need needs to be explained to the librarian as a search expert. The scope of this master thesis is to find how the librarian, tactically, can reach the users need despite lack of subject knowledge.
Högskolestudenters psykiska hälsa : Kartläggning av självskadebeteende
Background: The purpose of the present study was to investigate the prevalence and characteristics of deliberate self-harm in a Swedish University population.Method: A random sample of first year students at University of Kalmar was invited to participate in an Internet-based survey in the autumn of 2007. A total of 139 (53,1 %) completed the anonymous survey.Results: The results showed that 25,2 % (n=35) of the students reported having engaged in some kind of deliberate self-harm at least once, and deliberate self-harm was endorsed by 7,9 % within the past year. The most frequently procedures to self-harm were to tear, carve or pinch self, cutting skin and hitting self on purpose. 37,1 % reported that they had told no one about their self-injurious behaviors and 36,4 % significantly reported that they had no one they trusted and who they could talk to if they were concerned about something. Students with self-injurious behavior were also more likely to report a history of emotional, sexual and/or physical abuse, alcohol and drug use, cut classes and questioning their sexual orientation.Conclusions: Findings suggest that self-harm is associated with risk factors and that self-injury is not only associated with adolescence but also with adulthood.
Ett svenskt landskap i Australien : svenska kyrkan i Melbourne
As a Swedish landscape architecture student living in Australia for five
years, I have often wondered if my memories and my associations
with the landscape and the nature in Sweden, are the same as other
Swedish people living in Melbourne.
Most of the Swedish people who live here in Melbourne remember
and associate Sweden?s nature and landscape with where they grew
up or where they used to live.
The plants that most of the Swedish people I asked missed from
Sweden were associated to special feelings or activities. The general
type of landscape people remember from Sweden is that of a
landscape covered in forests, which you can walk freely through.
With these memories as a foundation and with inspiration from the
Swedish landscape architect Thorbjörn Anderson?s way of creating
places, by letting a few strong changes play against the existing
elements,2 but also with consideration of the climate and the severe
shortage of water that is current in Melbourne, will I create a design
concept for the garden surrounding the Swedish Church in Melbourne.
A design concept that will generate memories and associations to
Swedish landscapes..
STABILITET I INSOMNI, ÅNGEST, DEPRESSION OCH UTBRÄNDHET OCH RELATIONERNA TILLSTÅNDEN EMELLAN
Mental illness is today the leading cause of long-term sick leave and insomnia, anxiety, depression and burnout are among the most common conditions. The aim of the study was to investigate the stability of these conditions and how this is influenced by gender and age, as well as the extent to which these states are risk factors for each other. The participants were a random sample (n = 2336) from the general population in the age of 18-79 years. The results showed that stable illness was more common among women than men, and that stable illness decreased with aging. The stability itself was not affected by gender or age. Relations between the conditions were bidirectional and they constitute major risk factors for each other (odds ratios, OK = 2.37 to 6.46). The largest risk factor for a condition is, however, previous occurrence of the same problem. Previous burnout was found to be a significantly larger risk factor for future burnout than previous insomnia for future insomnia (OK = 9.63 and 5.74, respectively). The results suggest that insomnia, anxiety, depression and burnout, despite their differences, are similar regarding symptoms and underlying causes. The importance of early interventions to prevent comorbid conditions which are more complicated and more difficult to treat is emphasized..
Värdet av aktierekommendationer
This paper presents a study that evaluates the performance of stock recommendations issued on Swedish stocks during 2003. The selection of recommendations in this paper originates from banks, major brokerage firms and financial press located in Sweden. The total of 171 recommendations consisted of 99 buy recommendations and 72 sell recommendations. Forecast revisions presented in this paper suggest that Investment managers have no ability to predict performance winners, nor do their forecasts in general have any significant impact on stock prices. A mere 50 percent of the recommendations in this revision had a weak ability to outperform their benchmark indexes as in other similar revisions.
Bullerreduktion av hytt på Volvodumprar : Undersökning, mätning och analys
Too high levels of noise lead to various health problems and cost society billions of SEK peryear. In this thesis we have examined a model of the A40E articulated hauler at VolvoConstruction Equipment in Braås. We have tried to reduce cabin noise in an articulated hauler,while also providing a way on how to proceed with a machine when the cabin does not measureup to the sound requirement. The best way to find leaks were with a reference source of model4205 and its speaker HP 1001 from Brüel & Kjaer in the cab and then walk around and listen towhere the reference source was more prominent. In this way, we found that the edges and theplugs were sensitive areas.
Sinnlig stimulans i vaken vila : en studie av växter i en restorativ trädgård
Den här studien berör några av de miljöpsykologiska grunderna i Alnarps Rehabiliteringsträdgårds uppbyggnad. Den ger förslag på hur karaktären rofylld kan förstärkas och hur säsongen kan förlängas i den restorativa delen av välkomstträdgården med växter som tilltalar flera av våra sinnen.
Deltagarna som kommer till trädgården har i regel stressrelaterade åkommor såsom utmattningssyndrom och har varit sjukskrivna en längre tid. De är ofta mycket känsliga på grund av fysisk och psykisk utmattning.
Studier visar att deltagarna har behov av en kravlös miljö där de kan få vara ostörda.
Algoritmer för objektdetektering i SAR och IR-bilder
The first part of the thesis consists of a brief introduction to the general principles of target detection and the sensor-systems used. In the following part there is a theoretical description of the algorithms this thesis focuses on. The detection algorithms described in this paper are called Cell Average, Ordered Statistics, 2parameter and Gammadetector. Two different discriminators called Extended Fractal Features and Quadratic Gamma Discriminator are also described. The algorithms are tested on three different types of data, simulated SAR-pictures, authentic SAR-targets and IR-pictures.

Hur spelar man marimba egentligen?: Att som slagverkare hitta nya sätt att spela på.
I det här arbetet har jag undersökt hur mitt musicerande på marimban kan utvecklas genom att hitta nya sätt att spela på.Syftet är att försöka hitta och utveckla för mig nya sätt att spela på och också försöka skaffa en vana att spela på dessa mindre etablerade sätt på marimban. Tillsammans med mina egna erfarenheter och en litteraturstudie om hur marimban är uppbyggd, hur plattorna är stämda, hur rören påverkar och om mindre etablerade sätt att spela på har jag experimenterat fram och värderat ett flertal nya spelmetoder.Jag har hittat olika sätt att spela på där jag bland annat spelar med stråke, spelar flageoletter mm. Jag har spelat efter grafisk notation för att få användning av de olika spelsätten..
