Portföljoptimering som alternativ till indexfonder : Hur skulle en fond konstruerad enligt portföljoptimeringsmodeller utvecklas i jämförelse med index?

This paper investigates the possibilities to construct automatized portfolios based on optimizations strategies that could outperform comparable indexes. The study is based on time-series of Swedish stocks dating from 1986 to 2006. In the research four different portfolio optimization techniques were studied. These were: the Classical Markowitz Approach, Mean-Absolute-Deviation, Minimum-Regret and Conditional Value-at-Risk of which the three latter are based on generated scenarios. The behaviour of these models was studied for different choices of parameters such as backward time-horizon and targeted average return.

Anna Maria LenngrenEtt ?vittert? fruntimmer eller en ?huld? kvinna

The purpose of this thesis has been to explore in what ways Franz Kafka?s ?The Metamorphosis? can be read as a story of gender. By bringing together Judith Butler?s theory of materialization and Lennard J. Davis?s crip theory I have spoken of Dismodernity as the domain of abject bodies that have been repudiated by (post)modern societies as untintelligible and dysfunctional.

Lönearbetet, Arbetslösheten och Möllevången : En studie i arbetslöshetens vardag och dess platser

The study is divided into three parts ? the development of wage labour towards becoming the dominant norm in society, how this norm is challenged in a specific geographical context, and lastly a study of two unemployed individuals and their everyday activities, what and especially why certain behaviour occurs. The main purpose with the text is to study unemployed people in a specific geographical context in a overall society where wage labour is thought to be the norm. Questions that is being asked is how the unemployed individual works in a society where wage labour is the dominant activity for the day. This is connected to a study of Möllevången, a district of Malmö, where the wage labour norm can be thought of as being challenged.

Lokala skillnader i konsumtion av påväxtalger och terrestra löv hos en differentierad population av Asellus aquaticus

That ecological and evolutionary processes can take place on the same time scale is a recent insight. Today we also know that they are directly linked to each other. In the lake Tåkern, in year 2000, there was a structural change when phytoplankton declined and submerged vegetation, mainly stoneworts began to spread. This led to evolutionary changes in the aquatic sowbug, Asellus aquaticus which had previously been limited to the reed, most likely feeding on detritus. But then, sowbugs could exploit the new habitat in stoneworts and a new food resource in terms of periphyton.

Så tyckte jag det var... en retrospektiv studie av åtta ungdomars upplevelser av att vara på Staple behandlingshem

The aim of this university paper was to understand how eight former clients at Staple reformatory had experienced their stay there. The clients at Staple are young people between 13-20 years old, both boys and girls.The basic questions were: What picture do the clients have of the treatment they received?What has been, from their perspective, the most important during their stay? Do the clients think the time spent at Staple has helped them? And how do they describe their change, if there was any?We gathered the information from the youngsters with qualitative interviews based on a manual divided into covering different themesWe found that the time at Staple had been very positive for all the former clients that we interviewed. They described the relations with the staff at Staple as central for their rehabilitation. The most important task for the people that work there is to set a good example for the client, and to be role models.

Neospora caninum hos köttdjur i Sverige :

Neospora caninum is an intracellular parasite that was first recognized in dogs in 1984. The parasite is now one of the most commonly diagnosed infectious causes of abortion in cattle word wide. N. caninum is transmitted to cattle in two ways. They may be infected from eating food contaminated with oocysts from a definitive host or they may be infected in utero from an infected mother. The infection is transmitted efficiently from cow to her offspring and this can occur for generations.

Exosomes as a potential mechanism of intercellular spread of prion protein

Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.

Aktinos : genomgång av aktinosproblematik hos nötkreatur

Actinomycosis is a rare, deep-seated infection of the jaw of cattle that include the progressive enlargement of bone structures. It is caused by Actinomyces bovis, a gram-positive rod found as a normal commensal of the alimentary canal in otherwise healthy animals. This paper shortly describes Actinomyces bovis and its ability to cause "lumpy jaw" or actinomycosis in cattle. It will describe its pathogenesis, diagnosis, treatment and some clinical presentations. The incidence of symptomatic actinomycosis infection is quite low in Sweden today.

Påverkar suggors grymtande under digivningen smågrisarnas tillväxt? :

The pig is unique in the way that it gives birth to a large number of newborns in each litter. Because of this the sow has developed a special behaviour during suckling to ensure that not only a part of the litter gets all the milk. Milk is only available during milk letdown. The piglets have to massage the udder for a long time before letdown and the more piglets at the udder the sooner the milk comes. The sow has developed a special grunting pattern to let the piglets know when she is ready for suckling and to signal milk letdown. Our aim with this study was to investigate if sows have individual grunting patterns repeated over time. We also wanted to know if sows with a more distinct grunting pattern have better growth in their litters.

Smartphoneapplikationer ? ett värdeskapande verktyg? : I bank- och livsmedelsbutiksbranschen

The smartphone market is growing rapidly, between Google Play and App Store more than 25 billion apps have been downloaded since 2008. Today many companies develop their own smartphone applications (apps) for their customers. We believe that many apps are developed without much consideration about the actual value it brings to the customer, and through them, value for the company. Instead they create applications with hope of keeping the company modern. Developing and implementing apps in a business is neither easy nor free and must therefore add value to the business in some way.

Läsinlärning och självförtroende : Hur kan barns självförtroende påverkas vid läsinlärning?

In what French philosopher Gilles Deleuze labelled Control Societies, mechanisms reminiscent of censorship ? that is, restriction of information that administrators of power wish to regulate the spreading of ? are present in the concept of copyright. This kind of censorship has theadvantage of not being scrutinized by public eyes in the way that the work of institutionalized censorship agencies such as the Swedish Statens Biografbyrå was. It is not unlikely that expanded possibilities for punishing anyone who spreads copyrighted material will result in larger and larger areas that may not be accessed, as the avoiding of conflict and repressive actions will emphasize the behaviour to take detours around information that is deemed taboo and therefore suspicious and dangerous.The ACTA trade agreement is one proposed tool for such extended possibilities for punishment. This essay does not however claim that copyright and censorship are the same ? but rather that the institutional execution of power that was previously a matter of state censorship has a lot of similarities with current and prognosticated application of copyright laws by corporations.While claiming to protect the individual, the disciplinary power executed actually aims to protect the one executing it; the purpose of the power structure is to replicate itself..

Abdominellt ultraljud av vuxna nötkreatur : en praktisk guide

Ultrasound is a diagnostic aid often overlooked by the veterinary practicioner who works with farm-animals. However, it?s use increases, particulary for breeders where ultrasound has long been used to evaluate ovaries and to diagnose pregnancy or disturbances in reproduction. There is much knowledge in how to examine ovaries and uterus by transrectal ultrasound, but when it comes to doing ultrasound of other organs in the abdomen the knowledge is more limited. Cows are very large animals, so it is not possible to examine everything inside the abdomen with ultrasound, simply because the ultrasound beam has a limited penetration. There is also lots of gas inside the gastro-intestinal tract of a cow, mainly in the large intestine and the rumen, and that makes it impossible to examine the organs behind the gas since the ultrasound waves are reflected when reaching the soft tissue-gas interface.

The importance of Yeheb (Cordeauxia edulis) for Somali livestock production and its effects on body tissues when fed to Swedish domestic goats

This master thesis was conducted in order to investigate the effects of the browsing species Yeheb on animal tissues in Swedish landrace goats and to make a literature review in order to increase the knowledge of the importance of this plant for livestock production in Somalia. The evergreen Yeheb bush is a very important feeding source for grazing and browsing animals in Somalia during the dry period. Yeheb contains cordeauxiaquinone that stains the bones of the animals red/pink, which has been an increasing problem when exporting meat to foreign countries. In an experiment, two goats were fed dry and fresh leaves from the Yeheb bush for one and two months, respectively. The goats did not feed the intended amount of dry leaves, since the supply and palatability was not as high as estimated.

Sjuksköterskans attityder till patienter med självskadebeteende

Självskadebeteende har uppmärksammats allt mer i samhällsdebatten under senare tid. Sjuksköterskan möter ofta patienter med ett självskadebeteende. Syftet med studien var att beskriva sjuksköterskans attityder till patienter med självskadebeteende. Metoden var en litteraturstudie och datamaterialet bestod av nio vetenskapliga artiklar, publicerade mellan åren 2000-2007. Det analyserade materialet bildade tre teman som visade sjuskköterskors attityder till patienter med ett självskadebeteende: Ej rätt till vård, Erbjuder vård utan hopp om förändrat beteende och Rätt till vård.Det framkom att känslor som vrede, rädsla, misslyckande och hopplöshet var kopplade till attityderna till patienter med självskadebeteende.

Attacks on humans in Sweden by bear, wolf, lynx, wolverine, moose and wild boar in relation to Swedes? fear for these animals

It is not easy to understand people?s fears since they are not always a logical reflection of the danger in certain situations. This study is an attempt to give a scientific view of the potential danger that certain animals in Sweden pose and compare this to Swedes? fear of these animals. A report shows that Swedes? have a certain amount of fear for being attacked by a wild animal in the forest and this fear has increased for certain animals over the last years.
