Att skriva om händelse, tanke och känsla: en explorativ studie kring effekter av expressivt skrivande i skolmiljö på ungdomars emotionsreglering
As part of the project Self esteem and Life circumstances among teenagers (started by Johnsson, Lundh & Wångby at Lund University in 2006) results from pilot studies of expressive writing (intervention initially created by Pennebaker and Beall, 1986) among adolescents in six secondary school classes in Sweden were investigated. The study describes changes from pre-test to follow-up on adapted versions of Emotion Regulation Questionnaire and Emotional Tone Index. Different strategies for emotion regulation are focused: voluntary and involuntary engagement and voluntary disengagement (Connor-Smith, Compas, Wadsworth, Harding Thomsen & Saltzman, 2000). The study is explorative. Results show a tendency towards more frequent diary use at follow-up for participants in expressive writing.
Metabolit- och hormonnivåer som tidiga markörer för fruktsamhet och produktionsstörningar hos mjölkkor
During the last decades the fertility of dairy cows has declined in the same rate as the milk yield has increased. This is a result of the negative genetic correlation between milk yield and fertility, failure to show estrous signs and metabolic problems in the cow. The purpose of this review was to investigate the function of metabolites and hormones as markers for disturbances in fertility, health and production in the dairy cow. There are several metabolites that are suggested to indicate the cow?s energy balance.
Riskkapitalets inverkan på operationella investeringar - En jämförande studie av svenska portföljföretag
This thesis seeks to explain the effect of private equity ownership on the amount of invest- ments made in a company. We use three capital expenditure based key ratios to determine if there is a tendency for private equity owned firms to invest more or less than comparable companies. Our dataset involve 27 Swedish buyout companies that were sold by a private equity fund between 2001 and 2009. Each buyout is assigned a peer group of two firms in similar size and in the same industry. Firstly, we compare the key ratios to determine potential differences in the level of investment.
Traditionella växtbaserade läkemedel. : Är Echinacea och Ginkgo terapeutiskt verksamma?
SummaryHerbal remedies have been used for many years to alleviate various symptoms. They were used in ritual acts to reassure the Gods and as medication. Plants as rhubarb and ginseng were used in China long time ago. The Egyptians had knowledge of herbal medicine such as aloe, myrrh and henbane, 1550 BC. The father of medicine Hippocrates used a large number of herbal medicines, and had many theories on the subject.Different parts of the plant can be used to extract the active ingredients.
Laserexperiment för grundskola och gymnasium
This report discusses the development of lessons based on laborations for middle and high school.The purpose of the project was to research the possibility to affect students' attitude towards physicsthrough well-planned stimulating lessons. The lessons were based on the Light and Lasers OutreachKit, a teaching package made by the organisation Laser Classroom, and have been adapted for physicsin middle and high school. The lessons were developed on a pedagogical and didactical ground andwere improved with surveys and peer and self assessment. The lessons were based on laser light and itsproperties. One lesson covered the topic of single-slit diffraction, while the other treated geometricaloptics.
Hur styrning utan budget sker i praktiken : - En fallstudie på Ahlsell AB
På senare tid har en kritisk diskussion växt fram kring användandet av budget som styrmedel. Budgeten anses vara tidskonsumerande, resurskrävande och den anses även inte tillhandahålla relevant information, vilket har medfört att det finns företag som avskaffat budgeten som styrmedel. Men hur styrs företag utan budget och är det möjligt att styra ett företag utan budget? Det finns forskare som anser att företag som styrs utan budget får problem med planering, samordning samt styrning av aktiviteter då de saknar ett ramverk. Ahlsell AB är företag som har styrt sin verksamhet utan budget i 17 år.
Arbetslöshet bland utrikes födda på den svenska arbetsmarknaden : En empirisk analys av vilka kommunala faktorer som kan påverka den höga arbetslösheten bland utrikesfödda
Unemployment amongst Swedish citizens is higher within the group which falls under the designation foreign-born. The aim of this thesis is to examine which municipal factors that can explain the differences in unemployment amongst foreign-born relative to native born.The empirical models are examined with both cross-sectional data for the year of 2010 and panel data for the years of 2002-2012. The examination is implemented through a linear regression analysis of the type Ordinary Least Squares (OLS) and Fixed Effect regressions. A theory section will be presented where the theory on Non-Accelerating Inflation Rate (NAIRU), theories on discrimination and country-specific human capital are illustrated.The result from the cross-sectional data shows that the amount of foreign-born, the level of foreign-born immigrated from Nordic countries have a significant negative effect on unemployment amongst foreign-born. The general unemployment shows a significant positive effect on the unemployment amongst foreign-born.
Dolt i det öppna
Communication is a part of everyday life. The more sensitive information we handle, the more interesting the question around security of your information becomes. There are two ways of handling security around the information you want to communicate, either you control the means by which you are communicating. Or you control the way you communicate, making you able to use existing communication channels. Existing methods within cryptography enables two parties to communicate information securely.
Normalitet och styrning i en förskola för alla (Normalization and governing in a pre-school for all)
The purpose of this study is to analyze how special education is done in relation to what is considered "normal". The aim is to discuss how the normalization discourse appears in a pre-school for all and, by extension, how the need of special education is articulated in relation to the normalization discourse. This study also intends to discuss how the perception of what is normal affects special education in pre-schools. The study draws upon previous research within the special education area through which we make our position. Since there is only a few studies in this chosen field which are based on empirical data, our study indicates the importance of more research in this field.
Smältbarhet på ensilage och hö hos hästar i träning :
Horses are made to eat mainly roughage and it is essential for optimal health to offer them an
appropriate amount of roughage with good hygienic and nutritional qualities. To produce
good hay at the right time and be able to keep the hygienic quality until next summer is a
problem. This has the effect that horse owners today choose haylage and silage to a larger
extent. Science in this area is scarce, i.e. if the change from hay to silage has any effect on the
horse.
Energideklaration- Vad är det och hur ska det hanteras i fastighetsbranschen?
AbstractThe Energy Declaration is a law that will come into effect October 1: Th 2006. This report has Värnamo municipality as principal and shall clarify what the estate owner in general and Värnamo municipality in particular need to know about this law. Another part that is going to be dealt with is how large the future need for energy experts in this field will be, and which competence that will be demanded for them.The work will in general deal with simplified energy declarations for apartment houses and public buildings, since these buildings are the first to be involved with energy declarations.The energy declaration will consist of a number of important components.? Energy power i.e. how much energy the building consume? If the ventilation control is done? If the radon measurement is carried out? Recommendations of measures to improve the energy power? Reference value to compare the buildings energy power againstAccording to the law the declaration shall been made by an independent expert, which will need certain information for this.
CORRELATION BETWEEN ENDOMETRIAL MARKERS AND PREGNANCYOUTCOME IN WOMEN WITH UNEXPLAINED INFERTILITY
ABSTRACTA defect implantation process is the major reason for unexplained infertility. Estrogen andprogesterone are steroid hormones preparing the endometrium for implantation. They mediatetheir effect through their receptors: estrogen receptor alpha and beta and progesteronereceptor A and B, respectively. Leukemia inhibitory factor (LIF), which is also important forimplantation, mediates its effect through LIF receptor and the coreceptor, gp130, and is downregulated by suppressors of cytokine signaling 1. The aim of the study was to compare thelevels of the steroid hormone receptors and LIF related factors in the endometrium of twogroups of women with the diagnosis unexplained infertility: one that became pregnant afterassisted reproduction and one that did not become pregnant.
Barn till alkoholmissbrukare : en studie av barnens uppväxtvillkor och det sociala nätverkets betydelse
Our purpose with this paper was to examine what effect a parent's drinking problem can have for the children in the family. A combination of literature study and qualitative interview analysis was used. The most important research questions were: How do the parent's problems affect the child? In what ways can the social network around the child help it to develop normally despite problems in the home environment? To what extent a parent's drinking problem affects a child depends on many different factors. Based on earlier research and interview data we drew the conclusion that growing up in a family where a parent has a drinking problem has a negative effect on all children.
Lika handlare tänker olika : En studie om korttransaktionskostnader och beloppsgränser
As a consumer, you can use cards for payment more or less everywhere you go, however, it is not certain that the card can be used for all purchases. When a customer pays with card there arises a card transaction fee charged to the merchant. This is a big problem for businesses where transactions with small amounts are a large portion of sales. An observation at the beginning of this study showed that seemingly similar merchants have chosen to solve this problem in different ways. Some merchant?s refuses card purchases below a certain amount, while others accept card with any purchase.
FPGA baserad PWM-styrning av BLDC-motorer
This thesis work contains a litterature study about electrical motors in general and how PWM-patterns for brushless DC-motors can be made. A suitable method has been implemented as a simulation model in VHDL. A simulation model of a brushless DC-motor which describes the phasecurrents, torque and angular velocity has also been made. The motor model made simulations easier for the complete PWM-system. The design was synthesised and tested with a prototypeboard including a SPARTAN II FPGA.
