Abnorm avkastning utifrån Benjamin Grahams värdestrategi : Ett ex ante test för de svenska, amerikanska samt japansk aktiemarknaderna

Theability to beat the market is one of the most discussed topics in finance. Thereare very few investors that manage to accomplish this over longer periods oftime. Most of the financial research claims that this is impossible unless theinvestor increase the risk in the portfolio. However numerous of researchershave shown that it exist anomalies on the stock market which either indicatesthat the Capital Asset Pricing Modell (CAPM) or Fama and French three-factormodel fails to explain stock returns or that the market is not fully efficient.One investor that has claimed that the stock market is not fully efficient andthat it is possible to generate abnormal return is Benjamin Graham. Graham isone of the legends on Wall Street and he has shown that by using few variablesbased on public information, one can manage to beat the market over longer timeperiods.There arejust a few studies that have tested Graham?s criteria?s, however all of themindicates that they work but that the standard deviation might be higher forthe portfolios.

Nutrition och nutritionsstatus hos patienter med esofaguscancer

Aim Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07) is an international survey tool based on parents' estimation of their child's motor coordination skills. The purpose of this study was to investigate the validity of a Swedish version of DCDQ'07 by finding out how the classification of Developmental Coordination Disorder (DCD) via DCDQ'07 is consistent with the classification of DCD via the motor impairment test, Movement ABC.MethodIn the context of a larger study, a Swedish translated version of the parent survey DCDQ'07 were sent to 4000 randomly selected families with children aged 8 - 10 years in Stockholm County. The classifications "DCD" or "NOT DCD" with cut-off values ??of 56 (9 years) and 57 (10 years) were applied. Forty families were selected from 410 registered responses.

Löneutvecklingens bestämningsfaktorer i Sverige

The purpose of this essay is to acquire variables that explain and may be used as a base for wage estimation in the private sector in Sweden. The factors that are assumed to have an impact on wage estimation are based on earlier Swedish and international studies. Business survey data, which is based upon monthly questions to firms in various sectors of the Swedish economy posed by the Swedish National Institute of Economic Research, will be analyzed to find out weather they have an impact on Swedish wage settings or not. Tests including business survey data are yet rarely frequent, why this essay will be some kind of a pioneer within the area. To estimate significant factors that influence wage setting in Sweden, three different wage equations have been modeled and tested with a regression model.

Greklandskrisens påverkan på bankernas interna risker : En studie om svenska storbankers kreditrisk

Background: 2009 it has occurred a crisis in some of the member states of the European Union: Spain, Portugal, Italy, Ireland and Greece. Despite, some major banks in the world had begun to recover from the financial crisis that occurred from 2007 until 2009, there were still banks who found it difficult to survive. Greece is one of the countries that suffered from the financial crisis. The high budget deficit and the unsustainable debt are underlying the crisis.Banks as financial intermediaries have important function in a nation?s economy.

Effekter av funktionell träning och medicinbollkast för att optimera kinematic sequence och x-factor stretch i golfsvingen

The interest for functional strength training in golf has grown the last decade and scientists are always trying to find training stategies to improve the biomechanical aspects of the swing. Kinematic sequence contains a proximal-to-distal sequence order towards impact, and an effective kinematic sequence in the down swing begins with a rotation in the pelvis and follows by an activation in thorax, arms and club in the respective order. The rotational torques in the proximal segments wanders through the body and to the more distal segments to create an effective energy ? and power transfer at impact. The x-factor stretch is the seperation between the rotation in the pelvis and the thorax at the top of the back swing and at the beginning of the down swing.

Lamellrandsröta i hästhoven :

SAMMANFATTNING Jag har skrivit om en hovsjukdom som drabbar hästar, den engelska benämningen är White line disease. Det finns inget korrekt namn på svenska, men vi kallar det för lamellrandsröta. Den engelska benämningen är den mest använda. Sjukdomen kom in i Sverige i slutet av 1980-talet, man tror att det var via importerade travhästar från USA. När den i slutet av 1990-talet fick fart i Sverige började den också att bli ett problem. Ambitionen är att få en inblick i vad lamellrandsröta är och vad den samlade kunskapen är idag bland fackfolk och praktiker. Godtyckligt har jag valt ut och ringt runt och intervjuat ett antal personer som har stött på detta problem, hovslagare, veterinärer och hästägare. All fakta som inhämtats har jag sammanställt, men det finns fortfarande många frågetecken att reda ut. Ett bekymmer är att expertisen har så varierande kunskap och syn på sjukdomen. Idag vet man att det är anaeroba (syreskyende) organismer som orsakar rötan.

PlusTak

Today´s roofing of dwelling houses is a very time consuming procedure, which includes a lot of different steps on the construction site. Not only does it cost a lot of money, but often do problems with rot and mold occur in the attics of houses today. The use of prefabricated modules has seen a great breakthrough in the field of construction of dwelling houses; at least when it comes to foundations and walls, where this type of approach makes the construction process way more efficient. What no one previous has succeeded to develop is a corresponding system for roofs that meets the demands of a dwelling house. Accordingly the goal of PlusTak has been to come up with a proper module system for roofing of dwelling houses, where the roofing is completed to meet the demands of the Scandinavian market. During the project a lot of effort has been put into customer contacts and the usability of the product, as well in the manufacturing process as on the construction site. This development has gone hand in hand with several practical tests and tryouts.

Effekt av olika kvävegödselmedel på utvecklingen av klumprotsjuka i salladskål (Brassica rapa ssp. pekinensis)

The price trend on rapeseed the latest years has led to an increasing interest to grow the crop among many farmers in Sweden. The price trend has resulted in more than a doubling of the oilseed area since the early 2000s. For many farmers it is an advantage to increase cultivation of rapeseed because of the high proportion of cereals in the crop rotation on many farms, but it is not just benefits. The risk of the fields being infected by clubroot increases within frequent rapeseed cultivation and it often leads to subtantial economic losses. Clubroot is caused by Plasmodiophora brassicae that is a soilborne pathogen in genus Protozoa and its resting spores can be found in the soil for up to 18 years.

I havet av siffror och bokstäver : En studie om matematik- och lässvårigheter hos barn i andra klass

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.

Prefabricerade passivhusväggar

Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.

Nedfästning av oljemåleri på puts.En fallstudie från salongen på Mostorps slott i Halland

This thesis, designed as a case study, is about complications concerning conservation of a decorative oil paint on lime plaster from the drawing-room in Mostorp castle sited in the county of Halland in south-west of Sweden. The building was built 1878-80 with an exterior of granite. The interior walls were made of clay bricks, lime mortar and lime plaster. The oil paint is applied to a layer of putty. The combination of different materials, which are organic and inorganic, affects the movement caused by internal and external stress.

Flipped classroom i matematik i gymnasieskolan : Studie av en gymnasieklass som undervisats enligt olika undervisningsupplägg i matematikkurserna Ma 1c, Ma 2c respektive Ma 3c

I föreliggande studie undersöks hur ett undervisningsupplägg baserat på flipped classroom påverkar resultatet i en matematikklass på det naturvetenskapliga programmet, samt hur eleverna förhåller sig till ett sådant undervisningsupplägg.Klassen undervisades av samma lärare, men med olika undervisningsupplägg, i tre olika matematikkurser: Traditionell undervisning med klassrumsbaserade genomgångar i Ma 1c; inverterad undervisning i Ma 2c där eleverna före lektionstillfället tog del av en videogenomgång, för att frigöra tid för uppgiftslösning i klassrummet; inverterad undervisning i Ma 3c med tillägget att man i klassrummet använde sig av undervisnings­verktyget peer instruction.En enkät gjordes angående elevernas attityder till de olika undervisningsuppläggen. Vidare gjordes en jämförelse av klassens resultat på de nationella proven med resultaten i riket, samt med resultaten för en elevgrupp som undervisats traditionellt.Enkätsvaren visar att eleverna var mycket nöjda med flipped classroom, och att majoriteten ansåg att de lärde sig mer med flipped-classroom-baserad undervisning än med traditionell undervisning. Detta gäller elever på alla betygs­nivåer; elever med såväl som utan tillgång till matematik­hjälp hemma; pojkar såväl flickor. Elevernas inställning till peer instruction var mera splittrad.Jämförelsen av resultat på de nationella proven visar en tydlig nedgång i elevernas prestation mellan Ma 1c och Ma 3c. Den största delen av nedgången skedde mellan Ma 1c och Ma 2c, dvs.

Bogsår hos digivande suggor: inverkan av strategisk halmning och hull

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.

The effect of low light intensities and red light on heart rate, blood pressure, respiratory rate and activity in dairy cows

Today dairy farmers in Sweden are obligated to have lights turned on during night time in addition to the mandatory daylight inlet. This presents a cost for the production but many argue that it can be economically beneficial, especially in loose housing of dairy cows. In loose housing and even more so in herds with automatic milking, well functioning cow traffic during all hours of the day is crucial to optimise production. In order to keep the cow traffic flowing, lights may be an important management tool. It is also perceived among farmers with tied up stall that night light decreases the incidents of cows accidental stepping on their own or neighbours udders.
