Hypoadrenokorticism hos storpudel :
Hypoadrenocorticism (Addison´s disease) results from insufficient production of glucocorticoid and mineralcorticoid hormones from the adrenal glands. The disease is often difficult to diagnose in an early stage because of the multitude of associated vague clinical signs. The standard poodle is one breed presupposed to be at higher risk of developing the disease. The purpose of this study was to give a review of canine hypoadrenocorticism as described in literature, and to characterise Addison´s disease in a population of standard poodles in Sweden. Statistics on incidenceproportions by breed for hypoadrenocorticism from the database of the Swedish insurance company Agria are presented.
?Regeringen skyndar p? ?tg?rder mot g?ngkriminaliteten - En kritisk diskursanalys om hur media framst?ller f?rebyggande ?tg?rder mot g?ngkriminalitet
Gang crime has increased significantly in Sweden over the past decade, deadly shootings are
becoming more common. This led to the year 2022 being established as the deadliest year in
Swedish crime statistics since the police began compiling national statistics on shootings. Gang
crime is, therefore, a highly relevant topic in the Swedish mass media. Besides the mass media,
the phenomenon is also of interest to politicians and the general public. Because of the
escalation of violence in Sweden, daily reports discuss the measures that should be implemented
to combat gang crime.
Hur väljs värderingsmetoder för IS-investeringar, valet av PENG-modellen som ett fall
Att värdera investeringar i IS skiljer sig åt från värderingar av andra typer av investeringar. IS kan vara väldigt komplexa och därför kan värdet av en investering i IS vara svårt att värdera. Den svårvärderade nyttan som IS orsakar har tidigare sällan varit accepterad att ta med i värderingar på grund av att den inte direkt går att kvantifiera. För att på ett strukturerat sätt uppskatta den svårvärderade nyttan med IS-investeringar har värderingsmetoder för IS-investeringar utvecklats. En av dem är en svensk innovation, PENG-modellen (Prioritering Efter NyttoGrunder).
Jag skulle ju också vilja tänka lite : En kvalitativ studie om matematiskt begåvade elevers uppfattningar kring matematikundervisning
Matematiskt begåvade elever är i behov av lika mycket stöd, variation och utmaningar som alla andra elever. Därför är det viktigt att dessa elever inte kommer i skymundan och får ?klara sig själva?. Syftet med denna studie är att synliggöra matematiskt begåvade elevers uppfattning om hur deras matematikundervisning ser ut idag, hur de själva lär sig bäst, samt hur de anser att matematikundervisningen ska utformas för att de ska ha möjlighet att utvecklas efter sin fulla förmåga. Med stöd i teori och tidigare forskning valdes sex matematiskt begåvade elever från år 4 ut för att medverka i denna undersökning.
"Detta är inte bara en förvaring utan ett lärandehus!"- En undersökning om varför pedagoger väljer att arbeta medvetet med förskolematematik
Denna uppsats handlar om förskolematematik. Vad är det och hur gör man? Vi har observerat förskolor och intervjuat pedagoger som valt att arbeta medvetet med detta för att få veta varför de valt att arbeta med förskolematematik. Vi tycker oss märka att intresset för matematik i förskolan ökat, och vi tror att vi någon gång kommer att arbeta i en sådan verksamhet. Våra frågeställningar är: Varför väljer pedagoger att arbeta medvetet med matematik? Hur gör man rent konkret och vad betyder förskolematematik för de pedagoger vi intervjuat.
Att skriva sig till läsning : Möjligheter och begränsningar ur ett pedagogiskt perspektiv
This thesis intends to analyse conditions for a successful implementation of consociational democracy, as a democratic model in Afghanistan. The lack of critical reviews regarding the democratisation-process in Afghanistan initiated the purpose of this study.Lijpharts democracy model was used as the basis in the comparative study. Along with empirical evidence regarding how the complex process of democracy in Afghanistan is progressing, the study investigated whether the identified conditions occurred or not.The choice of which democracy model to use can be crucial for the democratic possibilities to even survive and become established in conflict-affected communities. The principle of consociational democracy is that it is an empirically based normative model that aims to organise the state in a way that works against the risks of majority domination and oppression against the minority.The empirical case study revealed that a majority of the conditions were not met, which then can counteract the possibilities for consociational democracy in Afghanistan. The study has critically examined the prospects for the success of consociational democracy in Afghanistan, and it can be assessed that there is a limited probability for a successful applying of this model..
Gymnasieelevers förståelse av enhetscirkeln och trigonometri : en undersökning av elevers förståelse av matematiska begrepp, samt vad lärarna anser att nyblivna matematikstudenter bör kunna när de kommer till högskola eller universitet
The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.

Representativa testnät försvenska eldistributionsnät
This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.
Managing Credit Risk: Assessing the Probability of Corporate Bankruptcy using Quantitative Risk Analysis
Managing credit risk might be the single most important business area for any commercial bank. The assessment of "good" and "bad" corporate clients is a important task for a creditor. A bad debtor is a corporate client with hardships in meeting the continous claims (interest payments) that a creditor requires. One way of evaluating or separating a "bad" client from a "good" client is to assess the propensity for the client to file for bankruptcy. This thesis examines 226 firms in the Swedsh market in the quest of predicting corporate bankruptcy.
Varumärkessamarbeten mellan LVM och EVM vid kategoriutvidgningar: En Fungerande Strategi?
This thesis examines the possible beneficial effects of a temporary cooperation between a national brand and a private brand. The main hypothesis suggests that if a national brand wants to make a category extension to a remote product category, it should be able to decrease its risk by affiliating itself with a private brand. The national brand should through such a brand alliance be able to borrow some of the flexible characteristics that a private brand possesses to increase its associations with the new category. The survey consisted of 800 questionnaires with different cooperations between a private brand (ICA) and two national brands (Tropicana and Bravo). These were handed out to students in the universities of Stockholm.
Matematik 1 ur ett kompetensperspektiv : Hur innehållet i kursplanerna och ämnesplanen för matematik 1 går att tolka ur ett kompetensperspektiv
Syftet med denna studie var att undersöka i vilken utsträckning de tre kursplanerna för matematik 1 (1a, 1b och 1c) samt den tillhörande ämnesplanen gick att tolka i form av kompetenser. Vidare jämfördes även kompetensfördelningen mellan matematik 1 och matematik A. Studien grundade sig främst i ramverket MCRF (Mathematical Competency Research Framework) som presenterar sex matematiska kompetenser, men vi tog även hänsyn till ytterligare sex kompetenser som återfinns i NCTM (The National Council of Teachers of Mathematics), KOM-projektet (Competencies and the Learning of Mathematics project) samt Adding It Up. Kursplanerna och ämnesplanen har granskats med hjälp av en kvantitativ textanalys där innehållet delats upp och kategoriserats till de olika kompetenserna enligt kompetensernas definitioner. Utifrån resultaten kan man säga att förekomsten av de totalt tolv kompetenserna är relativt jämnt fördelade inom matematik 1a, 1b och 1c.
En fri marknad för fritidshus? : Lokala effekter av regleringar inom fritidshusmarknaden ? En studie om boplikt för fritidshus med exempel från Ven och Bornholm
The purpose of this study is to highlight the second home sector in Sweden and Denmark, in a comparative study of regulations for the second home market, and residence requirement. Two attractive second home island destinations is being compared in Ven, Landskrona and Gudhjem, Bornholm. The study addresses issues such as the local effects of a regulation of the second home market get at a local level, and the effects generated by deregulation, as well as local people's opinions about second home regulation in a popular second home area in southern Sweden. This has been examined using a mix between qualitative method and quantitative methods, and the study is based on six semi-structured interviews from informants from Ven, Bornholm, and Gudhjem which has been analyzed throughout a thematic analysis. In addition to the interviews, diagrams from the Central Bureau of Statistics of Sweden and Statistics Denmark, and various real estate websites, and a field observation from Ven and Gudhjem will be presented.The result shows that show that the discussion on residence requirement has been going on for a long time in Sweden and Ven, but the local organizations found more disadvantages than advantages and are now looking in to other solutions, while other locals believes that there are more advantages with a residence requirement. In Denmark it?s revealed that there is recently started discussion between municipal decision-makers and local organizations about the regulations, and if it should be abolished or not.

Optimal spelstrategi för yatzy
This report intends to analyze the difference between the original rules and a modification of the rules for the Scandinavian version of the world famous dice game yatzy (yahtzee). Several works are made previously existing strategies for yatzy and Yahtzee.The study was conducted using the optimal strategy calculated and implemented in the programming language Java. The execution of the application to create the file containing the optimal strategy was running on leased powerful servers from Amazon and took just over six hours each.A simulated player played 100,000 games based on the strategy, to obtain data which then was used to plot graphs and analyze the expected score and its standard deviation. The expected value (mean) and standard deviation of the score for the possibility of three or four throws were 233.00 ± 44.82 and 280.07 ± 41.25.In view of the results drawn the expected conclusion that the four possible throws provides increased probability of getting a high score, unlike the case where the player may only be able to throw the dice three times. The fact that the variance is lower in the case of four throw session is equivalent to that the likelihood to get close to the expected value increases..
