Verbbenämning hos svenska barn i åldern 3;6 till 5;5 år : En studie av prestation på Action Naming Test
Verbbenämning innebär förmågan att benämna en bild utifrån den aktivitet som bilden illustrerar. I tidigare studier har det visat sig att barn tidigt i språkutvecklingen har svårare för verbbenämning än substantivbenämning (Gentner, 1982; Kauschke, Lee & Pae, 2007). Detta förklaras delvis av att verb är mer lingvistiskt komplexa än vad som är fallet för substantiv (Gentner & Boroditsky, 2001), samt att de är svårare att illustrera (Masterson, Druks & Gallienne, 2008). För att undersöka benämningsförmåga används oftast bildbenämningstest och för verb saknas ett svenskt test för barn. Föreliggande studie syftade till att undersöka verbbenämningsförmågan hos svenska barn samt att utröna om den svenska översättningen av Action Naming Test (ANT) är tillämplig på svenska barn.
Testarbetets svåra val
När det talas om test pratas det på ett sätt som om det vore ett nytt fenomen, men i själva verket kan rötterna spåras tillbaks till 1978. Det är först på senare år som test har börjat etablera sig mer och mer och nyttan med test bland systemutvecklingsorganisationer respektive testorganisationer. Människan omges ständigt av information vare sig det är av elektronisk, fysiskt eller annan form. Det är därför inte så konstigt att tidsåldern människan befinner sig i kallas för ?informationsåldern?.
Kontext, utvärdering och användarupplevelse : En studie om kontextens påverkan på användarnas respons vid utvärdering av användarupplevelse
In this paper we explore the relations between context and feedback generated in three user-centered evaluations of a flash-based game. Whether it?s the social context, the physical context or the degree of intrusion from the evaluator, they all contribute to the quality of the feedback received. The selection of test subjects is a narrow process, which gives the above mentioned factors different meaning. Contextual factors have shown to influence the feedback given within both usability and user-experience.
En simuleringsstudie för test baserade på Maximum Likelihood- och Maximum Spacingskattningar
Om vi har ett stickprov med X1, X2, ..., Xn oberoende lika fördelade observationer från en kontinuerlig fördelning med fördelningsfunktion F?, där ? är en okänd parameter, är Likelihoodkvottestet (LT) ofta en bra metod för att testa nollhypotesen H0: ? = ?0 mot HA: ?? ?0. För vissa typer av fördelningar saknar dock Likelihoodfunktionen övre begränsning (Ranneby, 1984) och (Ekström, 2013) vilket innebär att testet inte går att tillämpa då. Detta test jämförs med två nyare test, Ekströmtestet (ET) (Ekström, 2013) och Fidelitytestet (FT) som är ett modierat ET, som vi vet fungerar även i dylika fall. Under vissa generella villkor så vet vi att de tre testen är asymptotiskt ekvivalenta.
Hur står sig Modigliani och Millers teori om kapitalstruktur under hög- kontra lågkonjunkturer? : en studie av 30 börsnoterade bolag på den svenska marknaden
Problem formulation: This paper will examine how the capital structure of firms affects their market valuation by applying the Modigliani-Miller theory on Swedish listed companies in a boom and a recession. The study will examine whether it is possible to draw any conclusions as to whether companies with high debt to equity ratios are valued lower in a recession, in comparison to companies with low debt to equity ratios.Purpose: To empirically test the Modigliani-Miller theory of capital structure in a boom and a recession in order to see if the companies? market value is affected differently depending on whether they have a high or a low debt to equity ratios.Methodology: The essay has a deductive and a quantitative methodological approach. Data analysis was done through a correlation analysis, a regression analysis and a hypothesis testing.Theory: The Modigliani-Miller theory of capital structure with taxes states that companies with a high debt to equity ratios has a higher value. One of the risks with a high level of debt could be that during a financial downturn companies have more difficulty realizing capital and are thus more likely to go bankrupt.Conclusions: The study shows results that are contrary to the Modigliani-Miller's theory; all the correlation analyses between debt to equity ratios and market value are negative.

Nedskrivningsprövning av Goodwill - En kvantitativ
Since the year 2005 listed companies are supposed to use international accounting standards when they set up their group accountancy. One thing that has changed with the new standards is the accounting of goodwill and long-lived intangible assets. Earlier companies were supposed to write of their goodwill during the years they had expected the extra profit to arise. According to the new regulation, an impairment test shall be done annually, as well as when there is an indication of decreased value. According to IAS 36 point 134, the company shall provide information in their accountancy about the impairment test.The aim of this study is to find out if some companies may be willing to reveal less information in their accountancy, and if there are any factors that affect this.
PSQS ? Power Supply Quality Simulator
Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.
Betydelsen av tidig hantering av nyanlända försökshundar till en försöksdjursavdelning :
AstraZeneca in Mölndal (AZRDM) uses beagles bred at Rååhöjdens kennel in Örkelljunga for their research purposes. The staff wishes to have mentally stable dogs to work with, sine stress can effect the research results.
The purpose of this study was to put together the testresults from dogs delivered 2003 and 2004, to see if there is a connection between delivery age and testresult. We have also worked out a method to test if early planned handling of the dogs makes a difference on how the dogs later respond in a testsituation, and tried this method in a pilotstudy.
The data that we have based our calculations on is 172 dogs, divided into 108 males and 64 females.
We found a significant connection between the age at delivery and the testresult in contactability for female dogs delivered in 2003, where increasing age led to decreasing grades in the test at AZRDM. When looking at the difference in testresults between test number two at the kennel and the test at AZRDM we found a significant connection for female dogs delivered during 2003, ie the difference takes on a more negative value with increasing age at delivery.
We found a difference between the two sexes in our calculations.
Utlakning av tungmetaller från Skörby deponi
The purpose of this thesis has been to assess whether leaching from one particular Swedishlandfill site, Skörbytippen, is contributing to elevated levels of heavy metals in a ditch runningfrom the landfill site to the lake Mälaren in the communal region of Håbo kommun. Since theditch is stretching approximately five km downstream from the landfill site, in situ observationsand maps with known points of inflow was utilized to determine appropriate test points for thecollection of samples.Soil, water and sediment samples were collected and analyzed for content of organic material, pHand conductivity. Data on plant-available elements and total amounts of heavy metals wasacquired through ICP-analysis.The results show that the Skörby landfill is currently in the methane-forming anaerobedevelopment phase, which indicates that the concentration of free and complex-bound metals inthe leachate water should be low due to chemical binding with other landfill compounds. The pHof the sediment samples was generally one unit higher than the soil samples and some of themeasured data, such as pH and conductivity, show that an environmentally disturbing dischargeof some kind of strongly alkaline chemical(s) has been made from Benders? takpanneindustri inclose proximity to the landfill.
Hästavmaskningsmedels påverkan på miljö och välfärd
Healthy, natural pastures is very valuable for biodiversity in the form of both plants and animals. An efficient use of pastures helps to preserve biodiversity, but grazing animals needs to be de-wormed to keep them healthy and to prevent harmful parasites spread on the pasture. The awareness about the environmental impact of the frequent use of deworming agents is low among the public. Some people are unaware that the absorption in horses of anthelmintics is incomplete, which make the circumstances about enviromental effect important to investigate further. The scientific evidence in this area is limited and more studies and trials are needed to deepen the knowledge about the effects of anthelmintics in the environment.
Hörselnedsättning hos barn och ungdomar till följd av platinabaserad kemoterapi - en beskrivande litteraturstudie
Success in treatment with platinum-based chemotherapy against different types of cancer tumors is limited by side-effects such as hearing loss which can have a large impact on the individual`s quality of life. It is of great importance to continue with studies that address this complex of problems.Objective: The aim of this literature review is to investigate the impact of platinum-based chemotherapy on hearing in children and adolescents treated for different types of cancer.Method: A descriptive review of literature was made based on sources from 15 different studies on the impact of platinum-based chemotherapy on hearing in the target group.Results: The survey of the studies shows that platinum-based chemotherapy causes incidence of hearing loss by differing degree in the target group. Dosage of a platinum-based substance appeared to be the most significant factor. Treatment with both cisplatin and carboplatin was more ototoxic than treatment with only one of these. Greater risk for hearing loss was to a higher degree observed in younger children.
Testning och parprogrammering : Går det att effektivisera testning med hjälp av parprogrammering?
The purpose of this study was to investigate the possibility of streamlining the test process by utilizing pair programming. During the process, pair programming has been practiced as is defined by the Extreme programming (XP) software development methodology, with the other aspects of XP discarded. The focus of the testing itself has been toward unit testing. The methods applied has been with an experimental approach where 93 cases were attempted to be solved by either single programmers or pair programmers. What has been investigated in these experiments was the time needed to complete a case, how many test attempts were needed to solve the case, and how high a percentage of the cases were solved.
Demokrati och diskurs. En normativ analys av diskursiv påverkan på de demokratiska värdena öppenhet, ansvarsutkrävande och inflytande
The idea that I put forward in this thesis concerns the democratic system and the threat from discoursive impact on its core values. I focus my normative analysis on three of these democratic values: transparency, accountability and influence ? and what democratic problems the discoursive impact causes in conflict with them. I have used a critical discourse theory to define discourse and discoursive impact, by focusing on the process of discourse, rather than its nature. I deal with the political structure where I claim that the essential relation between citizen and politician is disrupted, due to lack of information and the imminent problems of the existing network society.
Hur unga flickor i åldrarna 12-19 årpåverkas psykiskt av media, i förhållande till sina kroppar : En litteraturstudie
