"Man kan ju inte gÄ runt och va rÀdd varje dag" : hur mÀnniskor upplever och hanterar klientrelaterat hot och vÄld i arbetet
Syftet med studien var att undersöka hur mÀnniskor upplever och hanterar risken att bli utsatt för hot och vÄld frÄn klienter i arbetet. En kvalitativ ansats valdes vilket innebÀr att fokus har lagts pÄ subjektiva upplevelser och erfarenheter av studieomrÄdet. Studien genomfördes gentemot SocialtjÀnsten frÄn tvÄ kommuner och urvalet bestod av intervjuer med elva socialsekreterare vars arbete innehÄller myndighetsutövning och kontakt med klienter. Analys av data gjordes enligt induktiv tematisk analys. Resultaten visade att det föreligger en risk att bli utsatt för hot och vÄld av klienter men den upplevs vara liten.
TRIM : ? Metod för att identifiera risker och uppskatta projekttider
ITT Flygt is a world leading company that mainly manufactures submersible pumps. A problem of ITT Flygt is that product development projects rarely manage to hold the estimated project time. It shows that something unexpected occurs in projects quite often, which results in delays. The delays can both be due to an optimistic time plan of projects and risks in product development projects which are not discovered at an early stage. This added with unforeseen delays makes it difficult for ITT Flygt to estimate the duration of their projects.The goal with the Master thesis is to examine a suitable method for simulation of project time.
Amning som preventiv ÄtgÀrd mot plötslig spÀdbarnsdöd : En litteraturstudie
ABSTRACTObjectiveThe aim of this study was to determine if and what kind of scientific evidence there is for the advice that breast-feeding can reduce the risk of sudden infant death syndrome (SIDS). The aim was to investigate research on the subject published in the last 15 years.MethodA systematic review without meta-analysis with relevant original articles published in the last 15 years.Main resultsAfter searching for articles 26 relevant articles were used for this study and two were excluded because of poor quality. Mixed results were shown on breast feeding and the risk of SIDS. Breast-feeding seems to have some protective effect but can?t be separated from known risk factors of SIDS.Plain language summaryBreast feeding can be regarded as a preventive measure against SIDS.

Optimering av satellitbredband offshore
To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

Piotroski ur ett riskperspektiv : En empirisk studie av 3- samt 4-faktors CAPM
An efficient market implies that the use of fundamental analysis should not result in excess return, and that any return exceeding the market average can be explained by compensation for risk, accord-ing to The Capital Asset Pricing Model (CAPM). The focus of this study is to test whether the suc-cessful investment strategy developed by Piotroski (2000) generates excess return on American data, after risk adjustment by using Fama & French?s (1993) 3-factor and Carhart?s (1997) 4-factor CAPM. Initially we form stock portfolios based on companies characterized by high book-to-market values, additionally, we divide them into different performance classes by ranking them with Piotroski?s (2000) measure of financial performance, F_SCORE.
Ădelmetall i portföljen : En jĂ€mförande studie om Ă€delmetallers diversifieringsegenskaper
A comparative thesis to study precious metals impact on a portfolio, during a long period of time, from the fourth quarter of 1986 to the third quarter of 2012. Five different portfolios are compared; three of the portfolios containing one of the following precious metals, gold, silver and platinum, the fourth portfolio contain all precious metals and shares, and the fifth portfolio containing only shares which is represented of OMXS30. This is done to determine the portfolio that generates the most return in relation to the least risk with the help of historical prices. Sharpe ratio is used to measure the profitability of precious metals by measuring the yield relative to the total risk. The study also measures precious metals correlation with shares..

Dog bite incidence and associated risk factors : a cross-sectional study on school children in Tamil Nadu
Dog bites pose a threat to public health globally and can lead to infection, disfigurement, incapacity, post-traumatic stress syndrome and even death. In geographical areas where rabies is endemic, bites from infected dogs account for over 90% of the human rabies cases.
Children have been proven to be at a greater risk of being bitten by dogs and subsequently contracting rabies than adults. In this cross-sectional study, a school survey was undertaken in association with a rabies awareness campaign in India, to investigate the dog bite incidence and various risk factors associated with dog bites as well as assessing the knowledge of safe interaction with dogs among children in the age group 10-18 years. A total of 1295
questionnaires were collected. 43.2 % (n=556) out of the respondents were boys and 56.8 % (n=731) were girls with a mean age of 14 years.
Sjuksköterskors attityder till handskar. En empirisk studie om att anvÀnda handskar i vÄrden dÀr det kan förekomma risk för blodsmitta.
Sjuksköterskor har flera arbetsuppgifter som innebÀr en möjlig kontakt med patienters blod och risk för en blodsmitta. Enligt föreskrifter frÄn Arbetsstyrelsen ska handskar anvÀndas av vÄrdpersonal för att förebygga smitta. Trots dessa föreskrifter varierar anvÀndningen av handskar bland sjuksköterskor. Syftet med denna studie var att undersöka sjuksköterskors attityder till att anvÀnda handskar i vÄrden dÀr risk för blodsmitta kan förekomma. En empirisk studie med kvalitativ ansats genomfördes.
Value at Risk - undersökning av Historisk simulering och varians- /Kovarians-metoden
I dagens finansiella marknad utsÀtts de finansiella aktörerna för risk pÄ sin strÀvan efter lönsamhet. BalansgÄngen mellan att maximera verksamheten och risk har öppnat ögonen och ökat medvetenheten om behovet av att utvidga sina krav pÄ att tÀcka upp kapital.EfterfrÄgan pÄ snabba, pedagogiska och sÀkra sÀtt att lÀtt kunna berÀkna risk har dÀrför snabbt ökat. Under de senaste Ären har det dÀrför blivit allt populÀrare att anvÀnda sig av riskmÄttet ?Value at Risk? vilket kan definieras som; ?En portföljs maximala vÀrdeminskning med en viss sannolikhet inom en viss tidsperiod? Jag har valt att göra en jÀmförelse mellan de tvÄ vanligaste modellerna som anvÀnds för att rÀkna fram Value at Risk, Historisk simulering och Varians-/kovarians-metoden. De tvÄ modellerna kommer att testas mot tre olika tillgÄngar, guld, valutakurs Sek/£ samt aktieindex.
Preventiva samtal om risk för infektioner vid injektionsmissbruk?ökar utbildningsintervention personalens kunskap och motivation?
Bakgrund: Personer som injicerar droger riskerar att drabbas av allvarliga infektioner. Tidigare studier har visat att personal som möter personer i risk inte har tillrÀckligt med kunskap för att erbjuda hÀlsofrÀmjande insatser.Syfte:Att kartlÀgga personalens kunskap om infektioner som kan drabba personer som injicerar droger,samt undersöka om utbildnings intervention ökar personalens kunskap och motivation till preventiva samtal.Metod:Totalt genomfördes fem utbildningar med 26 deltagare frÄn psykiatri-, och infektionsavdelning, samt ungdomsmottagning. Studien genomfördes med enkÀt före och en mÄnad efter utbildning. EnkÀten innehöll kunskapsfrÄgor och frÄgor om erfarenhet av preventionssamtal med personer i risk.Resultat:Studien visade att personalen saknade tillrÀcklig kunskap om smitta vid injektion av droger och att personer i risk inte i tillrÀcklig omfattning erbjöds information och stöd. Innan utbildning skulle enbart 60 % av personalen samtala om smitta vid injektion av droger om de fick frÄgor av personer i risk.
Ăvervikt och fetma hos barn och ungdomar : Orsaker, konsekvenser och Ă„tgĂ€rder
The purpose of this essay was to get some knowledge about how the situation was for children with overweight and obesity. I wanted to examine what experience about causes, consequences and measure the professionals, who meets children in different situations in their daily work had, and I wanted to find out which explanations current research had about the problem.The knowledge I have acquired during my work with this paper about the problem was that it was depending on many different factors on various stage in the child's life which influences and interacts with the child in its development. The risk that a child would develop overweight was amongst other things depending on the child's eating- and exercising habits.This habit was formatted for example by the circumstances in the family, availability of sweets/food and the choice of leisure time activities.The consequences for the overweight/obese children could be that the child did not manage to keep up with its friend's physical activities which led to a sense of rejection, risk of being bullied by friends, the risk of a damaged physical and psychic health. The problem was not easy to measure and all of the studies demonstrated that parental involvement is necessary in an effective treatment of childhood obesity..
Risk och osÀkerhet pÄ fastighetsmarknaden : London & Stockholm
Background and research problem: The former highly inflationary property market is currently undergoing a stagnation process. Investors have been used to annual growth figures in double digits,but now this is no longer considered to be a realistic outlook for future years. According to a report from PriceWaterhouseCoopers and Urban Land Institute, published by Avanza Wealth Management,the three most attractive markets for property investment in Europe are London, Paris and Stockholm. Because of this the authors have focused their investigation on two companies in the London andStockholm. The authors will additionally use an international bank, an estate agent and a consultancy firm for further information, with regards to the property market and risks associated with these typesof investment in particular.
