Selen och incidens av typ 2-diabetes - en systematisk översiktsartikel

Background: Type 2 diabetes is a disease which causes vascular damage, stroke and premature death.Oxidative stress may play a role in the development of insulin resistance and diabetes. Selenium is amineral involved in the protection against oxidative stress, and has been thought to be favorable in theprevention of the disease. However, this has changed since trials observed positive correlationsbetween high selenium levels and incidence of type 2 diabetes.Objective: To examine the studies that investigates seleniums effect on the incidence of typ 2 diabetesSearch strategy: Searches have been done in PubMed and Scopus.Selection criteria: Included studies were human studies in English/Swedish with RCT or cohortdesign with the aim to investigate the correlation between selenium and incidence of type 2 diabetes.Excluded studies were studies whose aim was to investigate the role of selenium in patients withexisting diabetes. Studies regarding pregnant women, animals or children and with in vitro design werealso excluded. Of the studies found in Scopus where MeSH terms were available, the ones who did notinclude relevant terms were excluded.Data collection and analysis: Studies were collected according to the aforementioned criteria.

Disputing the Economic Man - a quantitative study on whether investor decision-making can be distorted by altering the presentation of an Exchange Traded Fund

During recent years, financial innovation has given rise to numerous structured investment opportunities aimed towards the general public. These have enabled private investors to engage in high-risk investments offering as much as 400 per cent leverage while oftentimes not fully having grasped the risk involved. The issuers of these securities have been criticized for using advertising of a too aggressive and misleading nature.By presenting 819 potential investors with two different investment opportunities yielding the same return over a six day period, we have aimed to assess whether the inclination of being affected by judegmental heuristics varies with factors such as knowledge, overall attitude towards the asset class, risk appetite and experience from previous investments.We have observed that investors' perception of the attractiveness of an investment can be distorted by altering the information presented to the investor. However, our findings show that this tendency decreases with an increased level of knowledge, experience and risk appetite..

Undersökning av utökade användningsområden för Lotsbroverkets slam

Lotsbroverket is the largest wastewater treatment plant on the Aland Islands and it isdesigned for handling wastewater from approximately 30 000 persons. In 2011,Lotsbroverket produced about 2800 m3 of dewatered sludge. The sewage sludge that isproduced is transported to a contractor where it is processed to eventually be used e.g.in the construction of green space. This study aims to investigate available applicationoptions in terms of the sewage sludge that is produced in Lotsbroverket. The main aimis to study the feasibility of using the produced sewage sludge as a fertilizer in theagriculture of the Aland Islands.The sludge already fulfills limit values for heavy metals in accordance with the Act"The Aland Government´s directive on the use of sewage sludge in agriculture." Inorder to clarify the sludge content of pharmaceutical and organic substances it isrequired that the substances are identified and a risk assessment is performed.

Brucellosis in small ruminants : an investigation of knowledge, attitude and practices in peri-urban farming around the region of Dushanbe, Tajikistan

Landlocked Tajikistan is situated in Central Asia and is not only the smallest republic of Central Asia, but it is also one of the most mountainous with some of Central Asia?s highest peaks. Tajikistan is currently and historically the most financially disadvantaged country within Soviet Union/Russian territories. Agriculture is the main occupation for more than half of the country?s population. Unfortunately, however, only 7% of Tajikistan is arable land and the agriculture productivity is low.

Barriers to convert to organic farming and the role of risk : an empirical application on Swedish data

To understand the motives, and perhaps more importantly the barriers, for farmers to convert from conventional to organic farming is of great interest for policy makers as well as for academics. In Sweden and in other EU countries, proposed targets of the area in organic farmland have failed to be reached in spite of different kinds of policy measures. Most studies agree that the average profitability seems to be comparable to or better in organic than in conventional farming. This would indicate that there must be other factors of importance which can explain the low particiapation rate. A higher perceived risk in organic farming with respect to yield and price is frequently brought up as a potential explanation within a qualitative framework.

IT-stöd för riskhantering : En studie av risk och kvalitetsarbete vid ZERT AB

This paper presents a project and literature overview about how risk management and quality sometimes goes hand in hand and sometimes in two different directions. Meaning that the risk management can affect product or process quality differently depending on what risks an organisation chooses to control.The purpose with this paper is to get a deeper understanding about how risk and quality works together with IT-support and therefore we have been actively participating in a project with a risk management company called Zert. A literature study and a qualitative interview study have also been undertaken to see what the customers and the other researchers have written, to be able to make proper conclusions on the subject.To easily work together and get the information that was needed, four methods where used. Besides the qualitative interview and literature study the think-out-loud, card sorting and a variation on the extreme programming method where used to help visualize and improve communication both with Zert, the costumers and among ourselves.Zert is a risk management company that helps other organisations to control their different types of risks that they might be taking, by offering a system where the risk management process is held and providing consulting services by helping within the processes. Both Zert and their customers see the communication, knowledge and teamwork as something important as well as the quality within the work, processes and the end result.

Riskhantering i projekt : Modell för uppföljning

In April 2010 Vägverket (the Swedish National Road Agency) andBanverket (the Swedish National Railway Agency) will merge intoTrafikverket (the Swedish National Traffic Agency). Trafikverket willassume unified responsibility for the risk management that atpresent is responsibility of Vägverket and Banverket separately. Atpresent, as it will be shown in this thesis, Vägverket and Banverketshare the same theoretical background for risk management but usedifferent implementations often within the same agency. The use ofdifferent implementations results in a reduced transparency of therisk management both within and outside the agencies: this willbecome even more problematic when they will be fused intoTrafikverket.The aim of this thesis is to review the current risk managementmethodologies used at Vägverket and Banverket and to suggest aunified tool for the risk management at Trafikverket. This will bedone by focusing in particular on construction projects, one fromVägverket (Partihallsförbindelsen) and one from Banverket(Nynäsbanan).

Gränsöverskridande företagsförvärv : En event study av systematisk risk

Internationaliseringen har ökat under de senaste åren, och företag väljer att lägga delar av verksamheten utomlands. Tidigare forskning undersöker sambandet mellan denna diversifiering och dess konsekvenser för företagen. Gränsöverskridande diversifiering och företagsförvärv bör enligt tidigare forskning ge en lägre systematisk risk då risken sprids ut över flera marknader.Syftet med studien är att se om tidigare forsknings resultat går att tillämpa idag när svenska företag gör gränsöverskridande företagsförvärv. Vi har valt att applicera en event study-metodik för att undersöka detta samband enligt marknadsmodellen. Studien undersöker 66 svenska fall av gränsöverskridande företagsförvärv, gjorda under perioden 2005 ? 2007.Resultatet visar att tidigare empiri, att företagen skulle ha lägre systematisk risk efter ett gränsöverskridande företagsförvärv, inte går att tillämpa idag på de svenska företagen.

Riskkapitalbolags inverkan på risk för finansiell kris i portföljbolag: En studie av 53 transaktioner i tillverkningsindustrin

The aim of this small thesis is to investigate if the probability of business failure is higher at the time of divestment than at the time of acquisition for portfolio companies that have been subject to private equity ownership. The background for this thesis is the widespread critique aimed at private equity firms, claiming that they increase the risk in their portfolio companies. We have performed a study of 53 buyout transactions, involving Swedish manufacturing companies, covering a time span of 13 years, from 1995 to 2007. We find evidence of an increased risk of business failure for the portfolio companies with a short forecasting horizon (within one year). The absolute increase in the sample is however small.

Ett barns behov av akut skydd : En kvalitativ studie om socialtjänstens omedelbara skyddsbedömningar

The thesis had its starting point in the first paragraph of the eleventh chapter in the Swedish social services act, which discusses the immediate risk assessments that has to be made when the social services receive a report about a child. The thesis highlights an area that has received a lot of attention in media since the spring of 2014, when an eight year old girl was fatally abused by her legal guardians. The social services had at the time received a report about the girl but it was left unread. This tragic case has brought attention to the routines used by the social services for dealing with reports and risk assessments. This thesis was conducted through individual interviews with social workers working with children and families in the social services, with the aim to acquire an enhanced understanding of how social workers perform immediate risk assessments and what these assessments are based on.

Finansiell analys med avseende på risk: En studie av svenska fastighetsbolag

The purpose of this thesis is to investigate the status of Swedish real estate companies in terms of financial health and risk of financial distress. The background is the ongoing financial crisis, which partly can be derived from the American real estate sector. Publicly available accounting information from 16 listed real estate companies has been analyzed for a period of one year using financial ratios covering both the operational and financial activities. We find that the deceleration in the economy and in the real estate sector have forced the real estate companies to make large write downs, in line with the relatively new accounting rules, IFRS. Write downs are likely to reoccur during the following periods and real estate companies will therefore probably be forced to continue to show negative results.

Klassificering av processutrustning - en grund för riskbaserat underhåll

In this report a systematic working procedure for risk classification of processing equipment from a maintenance point of view is described. How this system has been worked out is also an important part of the report. The classification system is adapted for use in complex processing plants. Preemraff Göteborg has been subject for the underlying study and application of the system.The system aims to give a good overview of the maintenance related risks at the plant. Furthermore, the analysis result is a good motivation for the suggested maintenance activities and as motivation for extended or decreased maintenance resources in total.

Hedersrelaterat våld kombinerat med annan problematik - Om eventuella samband mellan utsatthet för hedersrelaterat våld och utvecklandet av psykisk ohälsa och/eller en missbruksproblematik

The purpose of this essay is to explore how social workers view a possible connection between exposure to honour violence and development of mental illness and/or substance abuse. We first heard of the possible connection from a voluntary organization who work in this field and who believe that this connection could be common. We therefore wanted to explore this from the perspective of social workers who come into contact with victims of honour violence: was this something they had noticed? How did they deal with it if it was noticed? We also asked how the possible connection could be interpreted and, supposing the social workers had failed to notice the connection, why this could be. We made five qualitative interviews with six social workers working in different contexts whom within their work come across honour-related issues.
