Background: 2007 there was 42 000 fall related accidents in Sweden and they are expected to increase the next few years. Fall among elders results in both increasing economically costs and suffering, but they can be prevented. For example has physical exercise shown an increasing effect on the risk for falls. Aim: The aim of this literature review was to investigate what influence Tai Chi has on the risk for falling among elder. Method: A literature review was conducted where eleven scientific articles were analysed with inspiration of the content analysis.

This study has been performed with the help of forest machine operators in order to improve the forestry planning at Holmen Skog Örnsköldsvik-region. For Holmen Skog forestry planning is basic for a successful forestry. In a survey I have investigated what can be improved in some areas that are planned for harvesting. The result of the investigation will be used to support the machine operators as much as possible. The study has generated 49.5 % of responses and because of this low response rate, no clear conclusions to anyone else except the responding machine operators can be drawn. It has been proved that there are some details in the forestry planning system that are inadequate, such as marked routs for trails, tractor paths and buffer zones against streams. The quality of forestry planning varies greatly between different locations, as much as 50 % of the responding machine operators thought so. Over 40 % of the responding machine operators claim that the information from Holmen is insufficient. One thing that would improve the forestry planning within Holmen would be to educate all forestry planners and then do continuous follow-ups..

Undersökningen syftar till att jämföra två olika urvalssystem för officersprogrammet. För detta syfte ställs det gamla respektive det nya urvalssystemet mot kadetternas studieresultat. Urvalskriterierna till dessa urvalssystem korreleras mot studieresultatet i en korrelationsmatris. Därefter undersöks de uppmätta sambanden medelst semi-partiala korrelationsmått och konfidensintervall. Detta skapar belägg för att det föregående urvalssystemet var effektivare än den nya för att välja ut kadetter med förmåga att tillgodogöra sig utbildningen.

The aim of this study is to describe and analyse the knowledge of three of the treatment methods used in youth welfare and this is accomplished through a knowledge review. This study contains an analysis of three different treatment methods described in eleven different peer reviewed articles. The articles are all internationally published between the years 2006 to 2012 and they are all effectiveness evaluations. The articles deal with treatment methods concerning Motivational interviewing (MI), Aggression Replacement Training (ART) and Cognitive behavioural therapy (CBT) and these are three of the most common in youth welfare in Sweden. There is not much knowledge of Swedish conditions and that is why this study focuses on international research.

This review paper summaries scientific research about horse thermoregulation and the consequences of using a blanket. Horse owners put blankets on their horses to protect them when they are clipped, to protect them from bugs, to keep them clean and so on. This can have consequences for the horse which their owners might be unaware of. I have tried to answer following questions by searching the available scientific literature; ? How can the horse maintain thermoregulation? ? Is there a risk of suffering when horses wear a blanket? ? Is there a risk of suffering when horses do not wear a blanket? ? How can animal inspectors estimate the welfare of horses when they wear or do not wear a blanket? My result shows that horses who wear a blanket have an increased risk of becoming overheated, develop a chafing, have an increased exposure hazard and have a restrained natural behaviour.

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

The purpose of this paper is to examine how teachers choose to work with the teaching of reading and writing skills, how teachers justify their choice of teaching method and how the documentation of student development is being used. This paper also discusses the definition of reading and writing, phonological awareness and how different reading- and writing educational methods can be combined. The gathering of information has been done through a literature review in which I have looked at past research on reading and writing. I have also conducted qualitative interviews with teachers involved in literacy learning. The result of my research shows that it is not possible to determine which literacy learning methods that are most effective.

This essay discusses people's perception of what is important for their well-being where they live. The main aim has been to find out what factors in the outdoor environments of the city are appreciated and why they are valued positively. A comparison has been made between Uppsala in Sweden and Tarapoto in Peru to see if, and in that case what, differences can be found in the values of people. I chose to carry out a survey study that got a response rate of 57 persons in Tarapoto and 63 in Uppsala. The results show that there are some common basic values, but on the whole the outdoor environments are valued differently in the two cities. In short, the Peruvians value functionality, cleanliness, small distances to family and service, while the Swedes value a central location and short distances to friends apart from functionality and good service opportunities. Conceivable reasons for this might be for example different cultural prerequisits, material standard and climate. .

This report shows methods and workflow when exploring the potential to change Outotecs HCD Silver Electrolysis machine to a module type. It?s done as an attempt to lower the workshop and installation costs and to give customer a more accurate prize directly. To do this a concept was produced which was set to a stress test. Additional objectives were to investigate freight and installation procedures, pneumatic connections and to calculate the difference in cost.Once the concept, a reinforced type of the original frame, was chosen stress tests in computer simulations were made and appropriate alterations were made.

This study aims to highlight and analyze eight secondary teachers' views and thoughts on mathematics. Hopefully this study will provide a deeper understanding of how teachers think and reason about their subject and how this affects their teaching. The study was conducted using a qualitative interview method, based on interviews with eight middle school teachers who teach in school mathematics for grades 6 - 9. The interviews were recorded and then transcribed and analyzed. After the interview analysis one can conclude that the teachers? thoughts concern three main themes: the importance of mathematics, children?s lack of basic knowledge and the teachers? lack of time.In discussion and analysis the teachers conceptions of the own subject is being analyzed, and that is the foundation of this study.

SAMMANFATTNING Syftet med denna undersökning var att försöka hitta de eventuella positiva effekter som kunde tänkas uppstå vid genomförande av arbetsplatsförlagd utbildning internationellt (utlands APU) för att i en förlängning kunna använda det som ett pedagogiskt hjälpmedel för de elever som studerar på Allhamra gymnasieskolas industriprogram. Materialet till undersökningen grundar sig på rapporter från Utbildningsdepartementet och intervjuer från elever på Allhamra gymnasieskolas industriprogram. Metoden som valdes var kvalitativa intervjuer med halvstrukturerad intervjuform och ett fenomenografisk beskrivande perspektiv användes vid återgivande av informanternas svar där en hermeneutisk tolkning av intervjuerna gjordes. Det slutliga deltagarantalet uppgick till åtta personer. Resultatredovisningen och resultatsammanfattningen visar att informanter som har genomfört utlands APU har fått yrkesmässig utveckling därmed nya kunskaper, de har även förbättrat sina språkkunskaper och fått ett stärkt självförtroende Det framkom även idéer hur studiemotivationen kan förbättras..

Tidigare forskning har visat att hundägare är mer fysiskt aktiva än de som inte äger hund. Deras motivation att vara mer fysiskt aktiv bygger på den sociala interaktionen med hund eller träningskompisar som hundträning/rastning medför. Med hjälp av Self-Determination Theory (SDT) undersöktes vad som motiverar just hundspannsförare att träna själv och hunden. Åtta personer som ägde hund och körde hundspann intervjuades. Frågorna kretsade kring tiden före och efter det att de ägde hund.

The purpose of the study was from the perspective of young people that has completed a stay at HVB-home. The respondents are between 15-21 years both boys and girls. The basic questions were: How do the respondents look upon this HVB-homes service process? How do the respondents look upon this HVB-homes service contents? How do the respondents look upon this HVB-homes service regarding available information and how the staff is available? What positive and negative experience do they have from their stay at the HVB-home? We also wish to get a picture of what is important to change to improve the quality on this HVB-home. To receive answers to those questions we formed a questionnaire.

Laboratory work is a big part of chemistry education in high school. During our student training placement we have noticed that the laboratory work is not fully utilized to develop students´ chemistry knowledge. This problem made us want to investigate how the laboratory work in chemistry could be set, to become more meaningful for students. We introduced two preparation methods, and examined the outcome of students learning experiences and their acquisition of chemistry knowledge. This was examined both through surveys and observation.

This paper investigates the relations between the fantasy genre and the phenomena of escapism. It also delves into the factors which motivates consumption of various fantasy mediums. This is done through interviews with six different fantasy-consumers, along with two observations; of which one is performed at a science fiction convention and the other at a table-top role playing game. The study resulted in a basic understanding of escapism ? it is not limited to the fantasy genre, and fantasy consumers do not deny that fantasy is a form of escapism.
