Myt och vetenskap om kastration av tik

This is a literature study in which I investigate if there are scientific studies that form the basis of the Swedish dog world views concerning the spaying of bitches. The positive impacts are said to be reduced problems with pseudopregnancy, reduced risk of pyometra, reduced risk of mammary and uterine tumors, an earlier cease of bone growth, a more active and happier dog and a bitch who is more tolerant of other dogs. The negative consequences are said to be urinary incontinence, increased aggressiveness, lower metabolism and the increased risk of obesity, a more lethargic individual and altered coat.There are studies indicating that spaying reduces behavioral problems associated with heat and pseudopregnancy. Assuming no ovary tissue persists after the procedure, and there is no progesterone production, the risk of pyometra decreases. Early spaying, before the first heat, reduces the risk of mammary tumors.

STABILITET I INSOMNI, ÅNGEST, DEPRESSION OCH UTBRÄNDHET OCH RELATIONERNA TILLSTÅNDEN EMELLAN

Mental illness is today the leading cause of long-term sick leave and insomnia, anxiety, depression and burnout are among the most common conditions. The aim of the study was to investigate the stability of these conditions and how this is influenced by gender and age, as well as the extent to which these states are risk factors for each other. The participants were a random sample (n = 2336) from the general population in the age of 18-79 years. The results showed that stable illness was more common among women than men, and that stable illness decreased with aging. The stability itself was not affected by gender or age. Relations between the conditions were bidirectional and they constitute major risk factors for each other (odds ratios, OK = 2.37 to 6.46). The largest risk factor for a condition is, however, previous occurrence of the same problem. Previous burnout was found to be a significantly larger risk factor for future burnout than previous insomnia for future insomnia (OK = 9.63 and 5.74, respectively). The results suggest that insomnia, anxiety, depression and burnout, despite their differences, are similar regarding symptoms and underlying causes. The importance of early interventions to prevent comorbid conditions which are more complicated and more difficult to treat is emphasized..

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.

Gränsdragningsproblemet i luck egalitarianism

The purpose of my study is to investigate whether luck egalitarianism can be savedfrom its inability to draw a line between risks which can reasonably be expected to beavoided, and risk which can not. Such a demarcation is of particular importance forthis influential theory of distributive justice, since it serves to judge whether a personis entitled to compensation for a bad outcome of a taken risk, or not. Testing theintuitiveness and coherence of various contending principles for how to separateavoidable risks from unavoidable ones, I conclude that luck egalitarianism seemsunable to draw a clear line between the two kinds of risks. Instead the theory appearsto be dependent on conceptions of a 'normal life', making it remarkably vague.Furthermore, I argue that luck egalitarianism seems unable to manage without takingsufficientarian and utilitarian concerns into account, for the purpose of decidingwhich risks are avoidable, and which are not..

Value-at-Risk : Historisk simulering som konkurrenskraftig beräkningsmodell

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

Samband mellan rating och framtida avkastning-En studie av Morningstars rating i olika börsklimat

.Syfte: Syftet med uppsatsen är att undersöka sambandet mellan Morningstars rating och framtida avkastning, samt om detta skiljer sig åt i olika börsklimat.Metod: Undersökningen bygger på en kvantitativ metod då vi har samlat in sekundärdata från dagstidningar och Internet. Den insamlade sekundärdatan kommer att ligga till grund för empirin då vi testar sambanden mellan variablerna rating och avkastning, risk och avkastning samt rating och risk. Teoretiska perspektiv: Uppsatsens teoretiska utgångspunkt är den effektiva marknadshypotesen och kapitalmarknadslinjen. Teorin grundas även på tidigare studier av bland annat Morey (2003).

Högriskfonder kontra aktieindex : En studie av makrovariablers påverkan på olika fondalternativ

Abstract  Title: High-Risk Funds vs. Mutual- Index FundsA study of macro -variables influence on different funds choice Level: Final assignment for Bachelor Degree in Business Administration Author: Moses Yokie & Bo Lemar Supervisor: Ogi Chun & Cheick Wagué Date: 2011-05-25 Aim: The purpose with this thesis is to compare two different types of mutual-index fond and a high-risk fund in relation to the macro variables. The purpose also includes an investigation about if an investor will receives a higher return on high-risk fund than on mutual-index fund in a 10 years period.Method: A quantitative method has been use in this study, where the information has been received from Morningstar. Microsoft Excel has been used to process the collected data in order to calculate the expected return and the risk measures. The result is presented in graphs and tables on the empirical capital, in order to analyse and compare it with the theories and the selected macro- variables to see if there will be any correlation. Conclusion: This research shows that there is no possibility that the macro-variable factors can benefit an investment on high-risk fund or on mutual-index fund in the short run.

Inverkan av leasingklassificering på konkursrisk - en studie av hur redovisningsbaserade prediktionsmodeller påverkas av en ny leasingstandard

The purpose of this bachelor-thesis is to investigate the possible effects of lease accounting on the estimation of bankruptcy. This is done by estimating the risk via prediction models based on accounting ratios for a sample of 43 listed firms in Sweden. Estimation is conducted twice for each firm, once base on unadjusted data as it is presented in the annual report of 2012, and one with data adjusted for operational leases (that is data is treated as if all leases present were to have been reported as financial leases). In the next step it is tested weather the predictive ability of the models is affected by this adjustment or not. For this purpose translation of bankruptcy risk into synthetic credit ratings via interest coverage ratios is done.

Fotogrammetrisk analys av kornstorleksfördelningeni erosionsskydd vid kraftverksdammar

This master thesis was made to investigate the possibilities of using the Matlab-basedsoftware Basegrain to determine grain size distributions of erosion protections onhydropower dams. Basegrain is a photogrammetric tool developed to generate grainsize distributions and other information about coarse flood sediments by analyzing adigital photo of the stone bed. The investigation was made by validating the ability forBasegrain to assess grain size distributions of various materials smaller than the blocksused in an erosion protection by comparing sieving results or manual measurementswith the results obtained by the program. A statistical comparison was then made bycomparing the results from sieving and the program. The possibilities of using thesame method on existing hydropower dams were then investigated by determiningwhether the method was practically viable or not.The results showed that Basegrain generated grain size distributions for coarse gravelthat were very close to the sieving results.

Riskhantering och kreditvärdighet : En undersökning av Enterprise Risk Management och dess relation till företags kreditbetyg

Background: Investors use companies? credit ratings as a base in their buy and sell decisions. Companies? credit ratings are also used as indicators of safety in the legislation. This means that credit rating agencies have an important role in the society because they communicate the company?s credit rating to investors and other actors in the society.

Att hjälpa andra trots risk : motivationen i det internationella biståndsarbetet

The purpose of this study is to examine what motivates people to help others at risk to themselves. The focus is on international aid workers, which in their work put themselves in situations of risk. Earlier research shows that international aid work involves risks such as infectious diseases, violence, death threats, assaults, constant insecurity and risk to be traumatized etc. There is not much research done on what motivates to help others in spite of risks, hence we find this an interesting area. We have interviewed six respondents about the content and character of their motivation and factors that are important for the maintenance and development of this motivation.

Självmord : en forskningsöversikt

Suicide is the ultimate outcome of mental illness and is a big and serious problem in society. About 1500 persons commit every year suicide in Sweden and many more engage in suicidal behaviour. This review aims at, from research studies from the 21th century, find out the knowledge of riskfactors regarding the risk for committing suicide among adolescents. The research questions are: What does research say, from a psychobiological perspective, about riskfactors among adolescents regarding the risk for suicidal behaviour? How much does genetic factors have an effect on the risk for suicidal behaviour among adolescents? and : What is the importance of environmental factors such as family connections, friends and school environment concerning suicidal thoughts among adolescents?The method that is used in order to answer these questions is a researchreview including ten research-studies.

Fondplacering i tillväxtmarknader vs mogna marknader

Syfte: Syftet med denna undersökning är att jämföra aktiefonders avkastning i  relation till tagen risk för tillväxtmarknaderna Afrika, Ryssland och en mer mogen marknad i detta fall Sverige åren 2008-2011.Metod: Till detta arbete används kvantitativ metod med deduktiv ansats. Information har samlats in i form av sekundärdata såsom fondernas kvartal avkastning från Morningstar.Teori: Standardavvikelse, Sharpekvot och Modigliani-Modigliani måttet används för utvärdering.Slutsats: Studien visar att den Svenska mogna marknadens aktiefonder har högst avkastning och lägst risk. Medan fonder med placering i den mer etablerade tillväxtmarknaden Ryssland har högst risk men varken högst eller lägst avkastning i förhållande till Afrika- och Sverigefonderna. Fonderna som investerar i den nyetablerade tillväxtmarknaden Afrika har låg risk likt Sverigefonderna men även låg avkastning. Samtliga fonder utom en hade negativt värde på Sharpekvot.

Bedöma Risk för våld hos frihetsberövade : Vad säger forskningen?

Att göra bedömningar av risk för våld hos frihetsberövade personer på fängelser och i olika former av tvångsvård är en viktig del av arbetet med att reducera antalet våldsincidenter, vilket är till nytta både för frihetsberövade personer och för personalens arbetsmiljö. Syftet med denna studie är att göra en kunskapsöversikt över vad forskningen säger om att bedöma risk för våld hos frihetsberövade personer, beskriva aktuell forskning om riskbedömningar, hur strukturerade instrument för riskbedömningar definierar våld, vilka teoretiska utgångspunkter till uppkomst av våld som används och i vilken utsträckning riskbedömningsinstrument tar hänsyn till interaktion mellan personal och frihetsberövade personer.Studien genomförs igenom en litteraturstudie med en innehållsanalys av forskning på området utifrån frågeställningarna i syftet. Sökorden är ?inmate?, ?inpatient?, ?violence?, ?risk?, ?assessment?, ?juvenile? och ?youth?.Reslutatet av studien visar att det finns ett flertal instrument som som forskningen visar har god validitet och även inter-bedömarreliabilitet för att bedöma risk för våld, nämligen Brøset Violence Checklist (BVC), Historical-Clinical-Risk management-20(HCR-20), Dynamic Appraisal of Situational Agression (DASA) och Structured Assessment of Violencerisk in Youth(SAVRY). Utöver detta finns även några bedömningsinstrument som använder enbart statiska variabler för att bedöma risk för våld hos frihetsberövade, även kallade aktuariska modeller.
