The purpose of this study is to investigate and describe the variation in perceptions of demands and expectations of study performance among a group of students at an upper secondary school. The study is inspired by a phenomenographic approach in which variations in perceptions of a phenomenon are of importance. Twelve students at a science program participated and were interviewed in groups of four. The results show that among the students there are several different perceptions of the demands and expectations to perform they felt present in their lives. The most important result is that it is the students' own demands and expectations on their performance and study results that are seen as the most demanding..

A shorter dry period length has in studies abroad showed some positive effects among high yielding dairy cows. Among other things it has been suggested that the periparturient metabolic stress becomes lower, that the fertility is improved and dry off becomes gentler for the udder, due to a lower milk yield. The milk yield is generally reduced during the first period after calving, especially among primiparous cows. The aim of this master thesis was to investigate how Swedish cows were affected by a shortened dry period, regarding milk yield, metabolism, health, body condition and body weight from two months before calving to some weeks after calving. Also plasma concentration of lactose during the period before calving was determined.

The starting point for this work was a discussion between my supervisor and myself during my teaching training. The discussion concerned the appropriateness of allowing students make films with sexual content. Film gives young people the opportunity to express their feelings and broaden their views. If the film then disseminates to unknown people via in-ternet, which it most likely will do, maybe it is no longer so positive. The aim of this study is to shed light on various aspects of identity and ethics that are important to keep in mind when young people in school make films.

To conclude this year?s introductory course in Mechatronics the students, in groups of 6,constructed a prototype based on the technical requirements established by the course teachers.This year they consisted of the following: two wheels only, active balancing, remote controlledand able to stop when crossing a pre-determined marker on the ground. The project lasted for 7weeks and the result is a working prototype and this report.The report reviews the chosen solution, subsystems and the finished prototype as well assuggestions for improvements, discussion and analysis.The prototype constructed embodied most of the group?s earlier individual technical specialtiesand consists of the following: a flywheel for balancing, ultrasound for angle measurement, areflective photomicrosensor to detect the marker and Bluetooth for the hand control..

AbstractTitle: Transparency within Public Relations ? A study about PR-companies understanding of opennessPages: 71Authors: Olof EhrsTutor: Virginia MeliánCourse: Media and Communication Studies, Bachelor Degree.Period: Autumn 2011.University: The Department of Journalism, Media and Communication, JMK,at Stockholm University.Background and aim: The PR-industry is continuing to grow in Sweden. The increase of working consultancies has made it more difficult to define what PR-activities really are in Sweden today. This exam reviews the presence and lack of transparency within the PR labour. The aim of the essay is to inspect the PR-companies relation to transparency and non-transparency.

The world around us is shrinking and globalization and capitalism are processes affecting the world. Global trends, like outsourcing and relocation of firms to low-cost countries, have become more common. This creates a huge vulnerability in the municipalities that today are concentrated around a single large company. One of these is Olofström which today is one of the most vulnerable municipalities in Sweden and whose survival today lies in the hand of the company ?Volvo Cars Corporation?.

This study is about children that have been forced to flee to another country, due to conflict, poverty or natural disasters, without their families. They are known as unaccompanied refugee children. The aim of the study is to, by focusing on individual children's feelings and experiences of being forced to flee create greater knowledge and understanding of what is hidden behind some of the statistic of migration.To answer the aim of the study, I used the following research questions: How is a child affected by being forced to leave home and to flee to a foreign country? How does an unaccompanied refugee child perceive the exodus? How do the unaccompanied refugee children handle their situation during the flight and at arrival in Sweden?The study is based on a qualitative method and consists in semi-structured interviews with five unaccompanied refugee children aged 17 to 21. The theoretical framework is based on three theoretical concepts; refugee crisis, identity and coping.The study results show that these children are a very vulnerable group, who were forced to be exposed to several losses and traumas.

This report is an evaluation of the cooperation between the rescue command centre and the POSOM-groups (?Psychological and social support?) after the Tsunami catastrophe in December, 2004. The report describes the interaction between these two municipal administrations, what services the rescue command centre provided and how they gathered information. Finally the author suggests different solutions to how the collaboration within these different municipal administrations can be increased and improved in future times of crisis..

It is not uncommon for math difficulties and reading difficulties to occur simultaneously. Despite this, math and reading difficulties are thought to have different cognitive profiles where math difficulties are linked to number sense; an innate ability to understand, approximate and manipulate both quantities and numerical information, whereas reading difficulties are linked to phonological ability; an innate ability to understand, create representations of and manipulate phonological information. A possible link between the difficulties is that phonological abilities also could affect mathematical ability. Support for this comes from studies where comorbid math and reading difficulties are associated with more severe difficulties in arithmetic ability compared to those with isolated math difficulties. The purpose of this study is to examine whether isolated math difficulties, isolated reading difficulties and comorbid math and reading difficulties can be linked to deficits in number sense, phonological ability or both of these, and whether comorbid math and reading difficulties differ in performance in mathematical tasks compared to isolated math difficulties for children in second grade.

This essay will try to explain and compare the different development steps which Croatia and Bosnia-Herzegovina have taken after the war. How could countries with such similar backgrounds develop in such different ways? By analyzing and comparing the two countries the purpose was to examine how these countries which had so much in common could develop in so different ways. My two questions are: What similarities and differences are there between the development which Bosnia and Croatia have taken after the war? Why have Croatia succeeded and not Bosnia?My analysis showed that the main reason to the difference between these countries was that Bosnia is divided; all ethnic groups in Bosnia only consider what's best for their own ethnic group and not what's best for the country. Croatia however has expelled the Serbs which made it easier for them to have a succesfull democratic development. .

Organic rearing of broilers is not a large production in Sweden. In order to create a sustainable yet efficient production of organically produced poultry meat, at a price that the consumers are willing to pay, much more knowledge is needed. It is therefore important to do more research on organic broilers under Swedish conditions. This report is aimed to be a base for further studies. In the study 2000 broilers of the hybrid Ross 308 divided in to two equal groups. The broiler hybrids that are used in Sweden are selected for a high growth rate and are normally slaughtered at the age of 5 to 6 weeks, with a slaughter weight of 1.7-2 kg.

Hard-to-heal ulcers are resource intensive due to the fact that they are difficult to treat and especially vulnerable to bacterial invasion. The bacterial culture contaminating these wounds often consist of several different bacterial organisms that originate from endogenous sources. Necrotic material in ischemic ulcers provide nutrition which support bacterial reproduction, increasing the risk of infection. Determining causative pathogen in infected ulcers proves to be difficult when culturing swab samples, however Staphylococcus aureus and hemolytic streptococci generally act as primary pathogens.    The aim of the study was to investigate if the detection rate increased for S. aureus and hemolytic streptococci when culturing swab samples from ulcers on Columbia CNA; a media selective for gram-positive bacteria.

AbstractAim: The aim of this study was to investigate if treatment with ?dry needling? in myofascial triggerpoints (MTrPs) in the rotatorcuff muscles may affect impingement symptoms such as pain during provocative tests, shoulder mobility, and function. The research questions were: Does the value of pain change on the Visual Analog Pain Scale (VAS) between before and after treatment? Do the positive provocative tests for impingement change between before and after treatment? Does the active shoulder mobility change between before and after treatment? Does the self-rated function change between before and after treatment?Method: The study was a prospective randomized intervention study and 19 persons with impingement symptoms (mean ± standard deviation; 58 ± 18 years, and shoulder pain duration 3.9 ± 1.6 months) were randomized into two groups. The groups were tested before, directly after and 3 weeks after treatment.

I uppsatsen utreds indirekta förebilders påverkan på svenska förtonåringars modeval av kläder och skor. Mycket av den forskning som gjorts tidigare berör andra marknader än den svenska och andra produkter än kläder varför vi anser vårt valda område tämligen outforskat. Vi redogör i uppsatsen för teorier som behandlar modespridning, barnens roll som konsumenter, kommunikation, varumärken, referensgrupper, self-concept, symbolisk konsumtion och familjens beslutsroller. Resultatet från de kvalitativa intervjuer som vi genomfört med pojkar och flickor i åldern tio till tolv år redovisas. Slutsatserna är att förtonåringarna har ett uttalat idolskap från i första hand sportvärlden och i andra hand musikbranschen.

The objectives of this experimental study were to investigate if a strategic method to supply loose housed sows with large quantities of straw 2 days before expected farrowing and if the sow?s body condition had any effect on the occurrence of shoulder lesions 5 weeks after farrowing. Data came from a study conducted on four commercial piglet-producing farms in southwest Sweden between March and December 2009. At each farm one batch of sows was followed during two consecutive lactations. The sows were randomly assigned to two different treatment groups and the sows that remained in the batch during the second lactation switched treatment group.
