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.

It is a common-held belief that the social worker for the most part uses oneself as a ?tool? in working with clients. This study seeks to examine that ?tool? in the context of treatment of teenage boys with psychosocial problems such as criminal behavior, drug-abuse and/or abusive home environment. The main purpose is to identify the conceptions of masculinity, and more specific hegemonic and subordinated masculinity, of the professionals working with the boys.

Companies today are exposed to a turbulent market with fierce competition and the ability toinnovate itself becomes increasingly important. But what innovation is and how it is managed is farfrom obvious. In this case study at EVRY the research questions are: ?What is innovation in ITconsultant companies?? and ?how can innovation be managed in IT consultant companies?? ITconsultancy is a complex type of business and their focus is often to innovate the customers businessrather than their own. The study is based on a literature review, field studies, unstructuredinterviews and an interpretive analysis.

The purpose of this essay is to study the role of web radio in Sweden. To fulfill the purpose we have done a case study of two Swedish radio stations: Sveriges Radio AB, which is a public service station, and a commercial station called Mix Megapol. By interviewing two persons from each station and analyzing the contents of their web sites, we have tried to see how the relationship between radio, Internet and web radio looks like. Thus, our method is qualitative. We have come to many conclusion of which some are: The new medium web radio borrows qualities from the traditional radio.

This study aims to compare two ethnographies of organizational culture ? one from the discipline of Social Anthropology and one from the discipline of Organizational Studies ? considering their purpose, their method, and their concept of culture. Despite big similarities, or perhaps thanks to the similarities, some fundamental differences are made visible. The discipline of Organizational Studies has, compared to that of Social Anthropology, regarding the research method being used, less focus on, and less participation in, the informal social life of the organizational culture of the study. Regarding the concept of culture the Organizational Studies consider culture containing more of unity, stability and clear boundaries, compared to Social Anthropology.

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.

This Master Thesis is a product development project that has been carried out incooperation with Metso Paper Sundsvall AB. The task has been to develop a holdingsolution that generates force between two rolls and to evaluate the new solution withrespect to functionality, manufacturing, structural stability, costs, assembly etc. Theroll holding solution is a system that is part of a rollpress. The rollpress is used towash and dewater pulp. The existing solution creates forces that have to be absorbedby the gable of the press.

The decrease in the number of dairy farms in Sweden has been ongoing for a longer period of time. But the fact is that this has previously not had any big effects on total amount of milk produced in Sweden. The main reason is that the remaining dairy farms get larger. However, during the past year, there has been a decrease in the total amount of produced milk, because the decrease is faster than the increase within the farms that are left. During the same period of time the supply of milk on the global market also has decreased. In spite of the fact that the global supply have decreased and the fact that the milk price increases, there are dairy farmers in Sweden who chose to exit the market.

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

Denna studie redovisar den frivilliga information som svenska VD och koncernchefer tar upp i VD orden i sina årsredovisningar. Syftet är att analysera var Sveriges redovisningsutveckling är på väg, genom att bland annat ställa de svenska VD orden i jämförelse med utvecklingen av öppenhet i årsredovisningar inom detta område i framför allt USA och Storbritannien. De undersökta VD orden kommer från årsredovisningarna hos de 18 svenska börsnoterade företag med högst värde på sin aktieomsättning år 2005. Eftersom det fortfarande inte finns någon fullständig teori inom detta område har ett induktivt förhållningssätt använts. De metodologiska val som gjorts är inspirerade av det som Glaser och Strauss (1967) kallar för grounded theory..

From an investigation by Finansinspektionen and KTH (2009) it is apparent that financial advisors and their clients develop relations, believing that they understand each other, while in fact, they do not. The media tends to notice the conflict of interests between advisors and retirement annuity clients. The aim of this study is to create a greater understanding as to why misunderstandings occur between advisors and clients. This will be accomplished by a quality study of how advisors and trade unions assess how the relationship functions. The theoretical part consists of theories concerning relations and uncertainty.

The collective agreement contains many important provisions concerning the relationship between employers and employees. When a collective agreement applies in the workplace, both employers and employees are bound by it. However, only employers of those two, can take part in the collective agreement, and therefore negotiate the content of it.The purpose of this study is to answer the following question: Why are rules that has been interpreted in collective agreements not expressed in writing? Therefore, the Swedish collective agreement system will be examined, and a distinction between types of silent regulations will be made to find causes. The potential for workers to act on a collective agreement with quiet regulations will also be examined.Collective agreements are signed on three levels: central, union and local levels.

The recent accounting scandals in large companies in both USA and Europe, such as Enron and Scandia, have led to a huge debate about the quality of financial reports approved by auditors who, at the same time, offer consultancy service to their audit clients. Many researchers and experts argued that there is a role conflict when an auditor offers consultancy service to audit clients. They argue that the main duty of an auditor is to verify the truthfulness of the company's financial statements. Giving consultancy service to the audit clients will impair the auditor's role to examine the company's books independently because of the economic bond between auditors and audit clients.As a result of the Enron scandal, the legislators in the USA have made restrictions to how auditors provide non-audit service to audit clients. However, the legislators in Sweden, unlike the US, did not choose to introduce such restrictions.

Denna uppsats beskriver fenomenet shared services, varför företag satsar på shared service centers (SSC) och hur de går tillväga när de designar dem. Studien har genomförts med hjälp av en litteraturöversikt och en fallstudie av TeliaSoneras nu pågående implementering av ett shared service center, FSS. Fallstudien består av fyra intervjuer och en genomgång av TeliaSoneras egna informationsmaterial och medarbetarenkäter. Litteraturöversikten visar att shared services utlovar väsentliga förbättringar av ekonomifunktionen och besparingar, att det finns en stor tilltro till dessa löften men att det saknas underbyggda bevis för hur stora besparingarna egentligen är. Designen på TeliaSonera FSS visar sig följa litteraturen relativt noga, förutom vad gäller placering.

Modern technology and fast development of heat pumps, the hunt for savings in energy consumption and the strive for environmentally friendly energy sources, convenience, and financial profit, have made heat pumps a reasonable alternative for the heating of houses.When the heat pump starts it will consume a considerable amount of current, which may result in a short-lived voltage-drop if the power grid is weak compared to the start-up current.The company Fortum Distribution which owns and administrates electrical network is interested in an investigation that deals with heat pumps affect on the quality of electricity.The purpose of this investigation is to study fast electrical fluctuations (flicker) as a result of start-up currents for single as well as multiple heat pumps on the same electrical station and from this evaluate whether there will be any problems installing heat pumps..
