Ungdomars syn på könsroller : en kvalitativ intervjustudie om hur ungdomar uppfattar vad som är manligt respektive kvinnligt
This paper presents a study of the attitudes and values related to gender young people have. Five people, four women and one male, all about eighteen years old, were interviewed about their attitudes and values related to gender.Although the study is relatively small, the results are compatible with other published studies and indicate that young people, without consideration to their sex, has a very traditional view on gender. The study also indicates that the attitudes seem to be established very early in life. Probably the most important factor to determine the attitudes and values of the child is the parent's opinions. The result show that the interviewed persons did not think their attitudes and values towards gender where influenced by media, TV etc...
The Reading the Mind in the Eyes Test - Revised Version á la Andersson & Karlsson
Introduction: The Reading the Mind in the Eyes Test is a widely used test for measuring aspects of social cognition. The aim of the present study was to provide results from a group of typically developing Swedish children (age 9-12) and to compare these results with children and adults in other Swedish and English studies, as well as results from a group of children with Asperger syndrome. Method: A Swedish version of the child version of the test was completed by 83 controls and by six children with Asperger syndrome. Results were compared between the two groups and with data from other studies. Results: The children in the current study did not differ on scores compared to children in the same age group in other studies.
Får idrottande elever högre betyg? : en fallstudie på tre samhällsvetenskapliga program för att visa eventuella samband mellan fysisk aktivitet och höga betyg
Abstract AimThe purpose of this study has been to investigate the possible differences in grades and attitudes towards further studies that can be explained by the student?s level of physical activity. The questions we wanted answers to were:- Does students in more sports-oriented programs have better grades than students in more theoretical programs?- Is there a relationship between physical activity and study-results?- Are there any differences in attitudes towards further studies for students at the different programs?- Which other variables could be affecting the students grades?Method The extent of this study has included 3 municipal schools and 6 classes (2 from each school) ? in all 119 students and 6 teachers. 3 different social sciences programs have participated ? two sports-oriented and one without any sports-oriented concentration .
Utvärdering av akupunktur som behandling vid ryggömhet hos häst : en pilotstudie
Acupuncture has been used for thousands of years in China. Written documents concerning veterinary acupuncture has been found dated around 650 B.C. Acupuncture has gained greater acceptance in the western world the last decades and many countries have established their own veterinary acupuncture organizations.
Many studies report good results after acupuncture treatment and back pain in horses is considered a good indication for acupuncture treatment. In studies published, the results are subjectively evaluated. To get a qualitative, scientific evaluation of acupuncture treatment, objective measurements, control groups and statistical analysis are needed.
This pilot study presents a case where acupuncture has been used for treatment in a horse that was diagnosed with back pain.
Riksintressen i den översiktliga planeringen
Riksintressesystemet har sedan det lagstiftades år 1987 granskats, diskuterats
och ifrågasatts. Tillämpningen av riksintressesystemet har ansetts haft
grundläggande oklarheter och problem, bland annat vad det gällde
riksintresseområdens aktualitet samt hur de skulle geografiskt avgränsas. Då
bristerna och problemen med tillämpningen av riksintressesystemet ansågs vara
av den omfattningen att det påverkade dess trovärdighet och legitimitet var det
intressant att studera hur riksintressesystemet tillämpades i praktiken, i den
översiktliga planeringen.
Syftet med arbetet var att studera hur riksintressesystemet tillämpades i
praktiken. Detta genom att undersöka hur Sveriges kommuner geografiskt
avgränsade riksintressen enligt 3 kapitlet MB i den översiktliga planeringen, i
förhållande till länsstyrelsernas underlagsmaterial. De metoder som användes i
arbetet var en litteraturstudie samt en kvantitativ studie, i form av en
enkätundersökning.
Resultatet av litteraturstudien och enkätundersökningen påvisade att det fanns
problem och brister med riksintressesystemet och tillämpningen av det, i den
översiktliga planeringen.
De slutsatser som kunde dras var att:
? Majoriteten av kommunerna geografiskt avgränsade samtliga riksintressen
enligt länsstyrelsernas underlagsmaterial, trots att ett flertal av
tjänstemännen angav att kvaliteten på länsstyrelsernas underlagsmaterial var
bristfällig i flera avseenden.
? Det fanns skillnader mellan olika riksintressen för hur de hanterades och
tillämpades i den översiktliga planeringen.
? De statliga myndigheterna, länsstyrelserna och kommunerna saknade
tillräckliga resurser, kunskap och kompetens för att kunna tillämpa
riksintressesystemet.
? Riksintressesystemet och tillämpningen av det genomfördes inte enligt
intentionerna i gällande lagstiftning..
LIP : en effektivitetsstudie
Lokala investeringsprogram was a subsidy program which supported environmental reforms during the years 1998 to 2002. The subsidies were given to Swedish municipalities. Most of the evaluations of the subsidised projects have now been completed and included in a database.
The purpose with this thesis is to analyse whether the instrument has been effective with respect to carbon dioxide reductions and costs. These calculations have focused on subsidy and cost efficiency. The analysis has been compared with a previous report called "LIP ur ett samhällsekonomiskt perspektiv".
The result shows that the reduction cost for one kg CO2 has been almost one SEK, which is twice as high as the cost reported in a previous report, half a SEK.
Biblioteksoro: i en svensk kontext
This Master?s thesis is the first to quantitatively study the prevalence of library anxiety at a Swedish university. Library anxiety is a concept describing the negative feelings students can experience when using the library. The study was conducted using web questionnaires sent out to 512 students at Växjö university. 38 % responded and the results were analysed with the help of, amongst other methods, correlation studies.
Bioenergy from the forest ? a source of conflict between forestry and nature conservation? : an analysis of key actor?s positions in Sweden
Bioenergy from the forest has been heavily debated in Sweden for several decades due to the interest of society to decrease dependence upon fossil fuels and limit the effects of climate change. The actual use of bioenergy from the forest has shifted over the years but increased during the last decades. Private actors within forest and nature conservation sectors play an important role for the development of bioenergy from the forest as well as for the debate and the implementation of political goals. Forestry in Sweden is characterised by ?freedom under responsibility? for private actors and the perspective of governance is valuable for studying actors and discourses.
Kommunikation i sociala medier : Nya utmaningar för organisationer
AbstractTitle: Communications through Social media ? new challenges for organizations Kommunikation i sociala medier ? nya utmaningar för organisationerAuthor: Jenny Lilius Location: University of Kalmar Language: Swedish Number of pages: 46 (62 including appendix) Level: BA Thesis in media and Communications StudiesAim: The main purpose of this thesis was to explore what kind of challenges organizations face when communicating through social media. Because social media is a new phenomenon the thesis also examined how organizations active in Sweden today looks upon, defines, monitoring what is said about them and uses social media today.Method: The thesis was based upon the qualitative gathering of empirical facts. Through deep interviews with five organizations and literature studies the author was able to gather the results.Theories The analysis is primarily based upon theories about organizational communications such as PR, Rogers?s diffusions of innovations and the marketing mix.
Infiltration av lakvatten från specialceller i bioceller -en effektiv metod för att förhindra spridning av metaller
Deponering är en metod som sedan länge använts för att behandla avfall. Metoden är dock kopplad till en rad miljöpåverkande faktorer, varav produktion av lakvatten är en. I lakvattnet finns bland annat lösta näringsämnen och metaller och dessa kan ge negativ påverkan på ekosystem om de sprids i miljön.Det här examensarbetet syftar till att besvara frågan om metaller i lakvatten kan retarderas genom att lakvattnet från en specialcell infiltreras i en biocell. För att besvara frågeställningen har mätvärden för ett antal kemiska parametrar analyserats på en deponeringsanläggning som ligger i Malmö och bedrivs av SYSAV.Arbetet avser även svara på frågan hur hårt biocellen kan belastas i fråga om hydraulik. Därför simuleras de förväntade uppehållstiderna av vatten i biocellen vid olika infiltrations-hastighet och porositet.För att ge resultaten tyngd har en litteraturstudie avseende deponering, hydrologi och hydraulik, lakvatten och metallers mobilitet i mark och vatten gjorts.Resultatet från litteraturstudien visar bland annat att lakvatten produceras genom att nederbörd perkolerar genom avfallet.
Prestation vid sönderdelning av GROT med olika typer av maskiner
There is a need for productivities data and data for different types of machines for comminution of logging residues. The lack of data and studies on GROT comminution makes it difficult to evaluate different chains for handling of residue fuels and make system analyses.Four types of machines with three different working principles were compared at six studies during winter conditions. Three to eleven trials during 9.5 to 30.7 minutes were made on each machine. Samples from the produced material at each study were sieved to determine the size distribution of the comminuted material. Samples were also taken from the studies for determination of moisture content.
Kan vi se, så kan alla det : En studie om hur blinda förhåller sig till Internet i Sverige idag och vilken betydelse det har för deras självständighet och delaktighet.
The purpose of this media scientific study is to contribute to a better understanding about how blind people?s empowerment and participation may affect their role in the digital society.Earlier international studies in this area have shown that blind people not only need more knowledge then the seeing population about the computer, but also about the technology behind their tools for using Internet. The results from these studies have also shown that Internet increases the blind people?s independents and that those who use Internet feel more involved in the society.A qualitative method was chosen to study the three most common categories from the earlier studies: knowledge of technology, empowerment and participation. Are there differences in the results compared to our study in Sweden 2014?Interviews with eight blind, experienced computer users have shown that knowledge of technology is essential for their use of Internet and that the Internet increases their empowerment and their participation.
SJUKGYMNASTIK SOM BEHANDLING VID LÄNDRYGGSDISKBRÅCK
ABSTRACTBackground: Most cases of lumbar disc herniation are asymptomatic. When symptomatic, LDH may cause a significant physical and mental distress. Initially, most patients are treated conservative but sometimes operations may be required.Aim: The aim of this study was to provide a review of the scientific basis of physiotherapy, including behavioural therapy, as a treatment to lumbar disc herniation regarding pain, function and the size of disc herniation in people suffering from lumbar disc herniation.Method: Four databases were used in the searches of literature. Assessment of the validity of the studies was done with the PEDro-scale and valuation of evidence rate was made according to guidelines made by the Swedish Council on Health Technology Assessment (SBU).Result: Nine RCT-studies were included with a total of 713 participants. The scientific basis is moderate to support a pain reduction and limited regarding improvement of physical function when it comes to physical exercises, including MDT.
Identifiering av fosfatfosfors käll- och flödesfördelning i ett litet jordbruksområde
Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.
Design av försöksanläggning för trycksatt rökgasrening vid oxy-fuelförbränning
Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.
