Behandling av fetma : Effekter på BMI, midjemått, vikt, ?Känsla av sammanhang?, kroppsuppfattning och självupplevd hälsa

AimThe aim of this study was to evaluate the effects of MotVikt´s obesity-treatment program on eight severely obese subjects, concerning Body Mass Index, Waist-Circumference and Weight after three and a half months and Sense of Coherence, Body Image and Self-experienced Health after three months. The question in focus was: Did MotVikt´s obesity-treatment program have any effects concerning the factors mentioned above?MetodInformation was collected with questionnaires that were filled out by the eight subjects, three men and five women, who participated in MotVikt´s last round of treatment. Data concerning waist-circumference, weight and BMI were provided by MotVikt. The questionnaires that were used to get information about Sense of Coherence, Body Image and Self-Experienced health were SOC-29, BSQ and IQOLA SF-36.ResultatThe average BMI in the group has decreased with 2,9 kg/m2, from 39,7 till 36,8.

Spårelement i Sveriges jordbruksmark : flöden, trender och fältbalanser

Field balances based on supply and removal of trace elements from the topsoil have been calculatedfor farms specialized in crop, dairy and pig production in Sweden. Today's field balances have beencompared with the field balances of 1990 in order to examine if, and then how, the situation haschanged. Studied trace elements are arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu),mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn).The balance calculations show that the stores of Cu and Zn are depleted with an average rate of -15% and -6 % over a 100-years period on crop farms when only commercial fertilizers are being used.The concentrations of Hg and Pb tend to increase in the topsoil on crop farms with more than 3 % forHg and with 2 % for Pb in 100 years. There is today balance between supply and removal of the traceelements As, Cd, Cr, Mn and Ni. In the south of Sweden, on crop farms with sugar beets in the croprotation, one can see a decrease in the concentration of Cd in the top soil by -6 % over a period of100 years.

P/E-talseffekten : Myt eller verklighet

Bakgrund: Finns det verkligen en investeringsstrategi som ger en garanterad överavkastning och som skulle kunna innebära att efterfrågan på de tjänster som professionella kapitalförvaltare tillhandahåller försvinner?Syfte: Syftet med vår uppsats är att undersöka huruvida det går att generera överavkastning på Stockholmsbörsen genom att investera i en portfölj enbart innehållande aktier med låga P/Etal. Frågan är alltså om det existerar det någon så kallad P/E-talseffekt?Genomförande: P/E-talseffekten testades genom att vi för var och en av våra 28 perioder fr.o.m. 1991 t.o.m.2004 skapade två portföljer där den ena innehöll aktier med de femton lägsta P/E-talen på Stockholmsbörsen och den andra innehöll aktier med höga P/E-tal.

Sänkt returtemperatur : Potentiell besparing i fjärrvärmesystem

Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.

Produktivitet vid stubbskörd :

Stump harvest could be found in the late 1970?s and the early 1980?s. And now when the prices on energy are high it has become an interesting topic again. This work has been conducted within Holmen Skog?s stump harvest testing in Norrköping.

Genererar insiderhandel överavkastning? : En studie om insiderhandel på Stockholmsbörsen

Bakgrund: Börsen ger en möjlighet för företag att erhålla kapital och för placerare atttillgodogöra sig avkastning. Personer med insyn i det egna företaget, så kalladeinsiders, kan dock i egenskap av sin position inneha kurspåverkande information somövriga aktörer på marknaden inte har möjlighet att ta del av. Tidigare forskning harpåvisat att insiders utnyttjar denna informationsasymmetri för att på så sätt tillgodogörasig överavkastning.Syfte: Syftet med studien är att undersöka om insiders kan tillgodogöra sigöveravkastning genom handel med aktier på Nasdaq OMX. Vidare ämnar studienutröna eventuella skillnader i överavkastning beroende på företagsstorlek,transaktionsstorlek samt tidsperiod.Metod: I denna studie har en kvantitativ forskningsstrategi i form av en eventstudietillämpats. Studien har en deduktiv ansats och undersöker insidertransaktioner från 90företag på stockholmsbörsen under tidsperioden 2006-01-01 till 2011-12-31.

??Finns det ett samband mellan graden av periodiseringar och inflationsjusterade skattade framtida rörelseresultat? : - Empirisk studie av den europeiska aktiemarknaden.

In line with Sloan (1996) but on European data (STOXX 600) we are investigating whether stock prices reflect information about future earnings contained in the accrual and cash flow components. The extent to which current earnings performance persists into the future earnings performance is shown to depend on the relative magnitudes of the cash and accrual components of current earnings. Moreover, we still find a significant positive excess return (Jensen?s alpha and size-adjusted return) by replicating Sloans (1996) hedge portfolio by taking a long position in the stock of firms reporting relatively low levels of accruals and a short position in the stock of firms reporting relatively high levels of accruals. However, we find no evidence of negative excess returns for companies with relatively high accruals, this somewhat lower the total excess returns for all the portfolios.

En analys av foderkostnader i mjölkproduktion

Animal welfare is impaired if the diet does not provide sufficient feeling of satiety or the ability to perform natural feeding behavior. Pigs are omnivores and spend most of the day searching for food by rooting, grazing and chewing. Both inability to perform foraging behavior and insufficient feeling of satiety often leads to direction of foraging behavior towards stereotyped and abnormal oral behavior. Dry sows are often fed restrictively which leads to unsatisfied feeling of hunger. Dietary fiber has been found to reduce stereotypic and abnormal behavior as well as aggression, which could indicate that pigs need to forage has been met giving a feeling of satiety.

3D-bootstrap - Konfidensintervall för guldfyndigheter

This paper deals with evaluating 3D-bootstrap for the mining company New Boliden in an attempt to revise their current method of calculating average gold riches in different areas. The purpose is to find one-sided 3D-bootstrap confidence bound of the average gold riches. There lacks well-defined theory behind using 3D-bootstrap, in this paper the variogram is used as an estimate of dependencies between the observations, and the block length is chosen to be higher than this estimate. In aid of this, a simulated data material is conducted to check the validity of 3D-bootstrap in a controlled area where the theoretical value is known. The results are inconclusive, and further studies are needed..

Goodwill, aktieägarens vän eller fiende? : En kvantitativ studie av hur goodwillpostens storlek pa?verkar fo?retags fo?rma?ga att ge avkastning till aktiea?garna

We investigate if the size of goodwill compared to total assets has any effect on the shareholders return on companies listed on the Swedish Stock market. We put up two different hypotheses with a foundation from previous research and later dismiss one of them. Our evidence does not show any indicators that the size of goodwill have an effect on the shareholders return, which brings us to believe that there, from a share holders point of view, isn?t any need for concern regarding the standards about accounting for goodwill as stated by IFRS. .

The thesis aims to study how rainbows families are being treated by the authorities and the surroundings. It focuses on how homosexual parents are met in society. Although, homosexuals have the legal right to have a family and enter into marriage, the social norms are still far behind and rainbows families are seen as ?the others? and abnormal.  Earlier researches have been studding how the authorities still assumes that every family are living in a heterosexual family constellation. By this assumption they exclude families who are not living in a heterosexual family.
