This thesis compares Auto Regressive Moving Average (ARMA) and Generalized Auto Regressive Conditional Heteroscedacity (GARCH) models for three metal commodities. ARMA models have an unconditionally non-random and constant variance, which typically serves well in effectively representing homoscedastic data. The GARCH models feature variable variance that is non-random when conditioning on the past
Uppsatsen syftar till att bidra till kunskapen kring hur man kan utvärdera riskhantering i allmänhet, och projektriskhantering i synnerhet. Uppsatsens undersökning avgränsades till verksamhetsområdet Investering på myndigheten Trafikverket och fokus låg på hur projektledarna arbetar med riskhantering i sitt dagliga arbete. Frågeställningen i uppsatsen har varit i vilken utsträckning riskhanteringe
Syftet är att undersöka börsintroduktioner i läkemedelsbranschen och huruvida de underpresterar gentemot valt index på lång sikt. Samband mellan prestation och utvalda variabler testas. Tidigare forskning visar på generell långsiktig underprestation vid börsintroduktioner, hur pass applicerbar denna forsknings är på läkemedelsbranschen testas i uppsatsen.The purpose of this thesis is to examine initial public offerings in the health care and whether they underperform or not in the long run. The correlation between the performance and chosen variables is to be tested. Earlier research shows that there generally is long-run underperformance present after an IPO, this study tests if this research is applicable in pharmaceuticals and biotechnology.
Röntgensjuksköterskan möter i sin yrkesutövning vårdtagare med olika bakgrund, däribland patienter från kriminalvården. Bemötandet av vårdtagare med olika bakgrund är en fråga om professionalitet i yrkesutövningen. Tidigare forskning visar att patienter från kriminalvården har upplevt kränkande attityder och offentlig förnedring i samband med vistelse inom den offentliga sjukvården. Syftet med den

Larvae from the non-biting midge family Chironomidae have previously been demonstrated to be sensitive to environmental pollution in aquatic environments. Exposure to different contaminants has resulted in an increasing occurrence of deformities of the mouthparts in the larvae. Common pollutions which induce mouthpart deformitys are metals (such as Pb, Zn, Cd, Cu, Hg, Cr, Ni), pesticides and some
Vad studenter väljer att studera på universitetet påverkas av många olika variabler. Syftet med studien var således att undersöka hur individers olika bakgrundsfaktorer samt personlighetsdrag utifrån Big-five-teorin påverkar deras val av utbildning. Studien undersökte relationen mellan socioekonomisk status, personlighetsegenskaper, kön samt etnicitet och studerades på studenter vid Lunds universiWhat students choose to study is effected by different variables. Thus, the aim of this study is to examine how different background variables and personality traits from the Big-five theory influence students choice of higher education. The study exam-ined the relation between socioeconomic status, personality traits, gender and ethnici-ty and their choice of study was observed on students from L
I Sverige finns det idag mellan 400 000 – 500 000 geoenergianläggningar och det uppskattas att nettotillskottet energi från geoenergianläggningar är ungefär 18 – 20 TWh per år. Geoenergianläggningar använder markens översta 300 – 500 metrar för att utvinna värme eller kyla. Vid anläggning av geoenergisystem kan man använda olika borrtekniker, mer eller mindre lämpliga beroende på olika geologiska There are about 400 000 – 500 000 shallow geothermal energy systems in Sweden and every year the net additions of energy from geothermal energy systems are about 18 – 20 TWh. Usually it is the upper 300 – 500 meters of the ground that are used for extracting heat or cold from cored strata. When constructing a shallow geothermal energy system, there are different drilling techniques available for u

Within the Swedish rail network, maximum track capacity is reached on multiple sections with costly delays as a result. Therefore minimizing the time a train is stationary after a disruption such as overhead line damage or suicide is important. Prior work has mapped stakeholders within the management of the two scenarios, but due to complexity, finding effective means of improvement is difficult.
This thesis explores the morphological integration of Standard Average European (SAE) words into Modern Standard Arabic (MSA). The topic constitutes a challenge insofar as SAE and MSA are typologically very different, and integration of words from SAE into MSA should therefore be generally difficult. Loanwords were selected from a collection of contemporary short stories and filtered through a Mod
Most current methods for studying cascading effects rely on written sources to extract information. This thesis presents an empirical method for studying cascading effects, when little written information of the event is available. The method presented has been influenced by incident investigation methods. It has been applied on a case of flooding in south of Sweden and revised based on the result
The aim of this report is to find cost-efficient fire safety solutions for saving lives due to fires in Swedish apartment buildings. This is done by evaluating existing systems through a cost-benefit analysis based on the value of a statistical life. The fire protection systems potential effects for different types of fires are evaluated based on a scenario analysis of the most common deaths due t
This study implicates research on outdoor pedagogies and a solution to support and extend pre-schools visits in nature environments. Pedagogies where daily activities take place in nature environments is growing among Swedish schools and pre-schools. Research about child development shows that free play outside has a number of positive effects on children’s health and well-being. Nature has proven
