Several industrial scandals, especially those about Enron and WorldCom, have lead to an intense debate about the independent audit and the independent auditor. A substantial part of the auditor’s income originates from counselling, and therefore the role of the auditor may be seen as double, and the auditor’s objectivity may be questioned. In the year of 2002, a new Auditors Act was legislated in Sweden. In the 21 § of the act, a model based on principles was introduced, to test the auditor independence in every single case. The question is if the new Auditors Act better ensures an independent audit than the preceding Act did. After the collapse of Enron, the international work on the development of rules that better can guarantee the independent audit, has been intensified. Will the wording and effect of the Swedish Auditors Act stand, will the international progress on this area influence the interpretation of the Act, or will the Swedish legislator be forced to rewrite the Act? Three problems are discussed in this thesis; 1. How shall an independent audit be ensured?, 2 What kind of activity may the auditor exercise?, 3 How should the auditor’s activities be organised to ensure the independence? This thesis describes howthe role of the auditor and his independence is regulated today, partly by legislation, partly by self- regulation, both national and international. Different regulations are compared and differences and similarities are described. A number of specific problems that may influence the independence of the auditor, in relation to his clients, and a discussion about how these problems may be avoided, is presented.

This study utilizes correspondence, memoirs, and secondary sources to explore the lives and careers of six Continental Navy captains?Esek Hopkins, Joshua Barney, John Paul Jones, Hector McNeill, Lambert Wickes, and John Barry?and reveal the motivational factors of patriotism, a desire for fame and professional advancement, and financial stability which underlay their decisions to seek commissions in the Continental Navy, and influenced their conduct while in the service. Additionally, it suggests that prewar interactions in an "Atlantic World" context influenced the ideological and personal motivations that formed the foundations for service in the Continental Navy. All three motivations played a role in each captain's career and affected their conduct in relation to their understandings of duty, but the degree to which they influenced the captains varied. Although the promise of a steady income helped motivate initial service, financial considerations played a larger role throughout Barney's and Barry's careers than they did for other captains. The desire for fame and personal prestige also affected the conduct and service of all six men, though Jones and Hopkins provide more concrete examples of its influence. Finally, experiences interacting with West Indies and Atlantic trade networks before the war likely influenced the captains' development of revolutionary principles, and their dedication to the United States. In addition to patriotism, Jones professed a devotion to universal principles of liberty and rights, and McNeill perceived the Revolution as an attempt to establish God's Kingdom of the Just. The degree to which each captain succeeded in achieving his goals, and the affect his Continental service had on employment after the Revolution, also varied significantly. Hopkins failed as the navy's commander-in-chief, but his performance did not negatively impact his social and political standing in his native Rhode Island. Unlike McNeill, Captains Barry, Barney and Jones also utilized their networks of friends and acquaintances well, helping them find prestigious and stable employment in other seagoing capacities after the war. Wickes died in 1777, but his brief service also suggests he would have achieved success had he survived.

The aesthetic aspect of a functional product is growing to be an important reason for the consumers choice to buy the product. Despite this importance, aesthetics has not generally been incorporated into engineering design which makes much sense of functional and ergonomic designs. The study presented in this thesis aims to remedy this observed gap. The study focuses on the integration of aesthetic attributes with functional attributes of a product and on the quantification of the aesthetic principle from fine arts into design variables of the product. In particular, two hypotheses underlie this study: (1) design variables can be classified in terms of their relevance to functional, ergonomic, and aesthetic attributes, and (2) a particular aesthetic principle, namely visual balance, helps to achieve an improved aesthetic product.<p>The cell phone is used to ground this study. A statistic experiment using the cell phone product positively tests the first hypothesis, resulting in two design variable which are only related to the aesthetic attribute of the cell phone product. The study of the visual balance principle results in a more general formula which relates design variables to visual balance with consideration of both geometry and color of the cell phone product. Finally, another statistic experiment is designed, which positively tests the second hypothesis.<p>This study concludes: (1) the effective integration of aesthetics with function and ergonomics requires an analysis and classification of design variables, and (2) there is a potential to quantify all aesthetic principles from fine arts into design variables.

This study examines whether there is an association between the length of the client-auditor relationship and audit quality, using absolute unexpected accruals estimated by industry as a measure of audit quality based on a modified Jones model. The study is motivated by the proposal on mandatory audit firm rotation for publicly traded companies from the European Commission, which is based on the notion that longer auditor firm tenure creates a familiarity threat which reduces the audit quality. Both the relation between audit quality and auditor partner tenure and audit firm tenure is examined in this study, using multivariate regression controlling for auditor type (Big 4 versus non-Big 4), signing auditors (one versus two auditors), firm size, profitability, leverage and age. There is a significant negative relationship between audit quality and audit partner tenure when only companies employing Big 4 is tested, which indicate that auditors constrain managements extreme accounting measures with longer tenure. The results provide no significant evidence of an increase in the absolute unexpected accruals with audit firm tenure, when only Big 4 companies are tested. The results also overall suggest that the audit quality is lower for shorter tenure relative to longer tenure, which is consistent with previous studies. The results of this study therefore implies that under the current regime with no obligation of firm rotation, longer audit tenure is on average associated with auditors in greater extent constraining managements extreme accounting choices. The results therefore do not support the call for mandatory rotation. However, the majority of the regression results were not statistically significant, which limits the possibility to apply these results to a population outside the scope of this study. / Revisorers oberoende i förhållande till sina klienter har under de senaste åren med anledning av finanskrisen samt de omtalade revisionsskandalerna medfört diskussioner om huruvida den befintliga lagstiftningen som reglerar revisorers arbete är tillräcklig. Det har även diskuterats om det behöver vidtas ytterligare åtgärder för att säkerställa revisorernas oberoende. Som ett led att stärka revisorernas oberoende har Europeiska Kommissionen lagt på förslag att införa obligatorisk byrårotation för publika bolag. Det har redan införts obligatorisk revisorsrotation. Dock anser emellertid kommissionen att detta inte är tillräckligt, då långa revisionsbyråuppdrag kan vara skadliga för oberoendet på grund av att det med tiden kan skapas en vänskaplig relation mellan revisionsbyrån och klienten. Majoriteten av tidigare forskning på området har emellertid inte funnit stöd för att varken långa partneruppdrag eller byråuppdrag skulle vara skadliga för revisionskvaliteten som omfattar revisorers oberoende. I studien undersöks således huruvida det finns ett samband mellan längden på revisionsuppdraget och revisionskvaliteten. Studiens syfte är därmed att undersöka om längden på partneruppdraget och byråuppdraget påverkar revisionskvaliteten. Utifrån studiens resultat syftar studien även till att kommentera rimligheten i Europeiska Kommissionens förslag på införandet av obligatorisk byrårotation. Studien utgår ifrån ett intressentperspektiv, eftersom det i slutändan är intressenter såsom aktieägare, investerare, långivare, anställda, kunder och staten som drabbas av de negativa konsekvenserna av att revisorer inte är oberoende i sin granskning, då tillförlitligheten till årsredovisningarna minskar.    De teoretiska utgångspunkterna baseras på tidigare forskning inom revision och företagsekonomi. I studien tillämpas teorier och tidigare forskningsresultat som främst gäller revisionskvalitet, vinstmanipulering och längden på partner- samt byråuppdraget i syfte att beskriva den befintliga forskningen som vid tiden för studien behandlar ämnet. En kvantitativ metod med ett deduktivt angreppssätt efter den positivistiska synssättet har använts för att på bästa möjliga sätt undersöka studiens uppställda problem och syfte. Urvalet består av publika bolag börsnoterade på NASDAQ OMX Nordics Large, Mid och Small Cap listor. I linje med tidigare studier används oväntade periodiseringar beräknad utifrån branschtillhörighet som mått på revisionskvalitet.    Resultaten visar att partnerlängden är signifikant negativt associerad med de absoluta oväntade periodiseringarna när endast företag reviderade av Big 4 studeras, vilket indikerar att revisorer begränsar företagsledningens möjlighet att genomföra extrema redovisningsbeslut i takt med att längden på partneruppdraget ökar. Resultaten ger inget stöd för att långa byråuppdrag påverkar revisionskvaliteten negativt, detta då inga signifikanta samband observerades. Studiens resultat visar även att korta revisionsuppdrag överlag har högre oväntade periodiseringar i förhållande till längre uppdrag. Studien ger således inget stöd för införandet av obligatorisk byrårotation.

The aim of this thesis was to study elderly people’s experiences of and approach to their usage of home care services with tax deduction. The aim was also to describe how elderly people reason about their underlying motives of using home care service with tax deduction. The study is based on six qualitative interviews with people between the ages of 65 and 80, living in Nacka, Sweden. This thesis is a collaboration with Stiftelsen Stockholms läns Äldrecentrum/ Stockholm Gerontology Center and part of their follow up study concerning simplified administration for elderly people applying for home care services in Nacka. The theory of rational choice was used in the analysis of the results. The primary results showed that elderly people’s usage of home care services with tax deduction was limited though regular and consist mainly of basic domestic work. The overall experiences of using home care services with tax deduction were positive and described in terms of satisfaction and as a possibility of independence and influence regarding their needs of services and how they were executed. The results indicate that the usage of home care services with tax deduction is partly based on elderly people’s lack of confidence in publicly-financed elderly care. Due to the distrust in elderly care and the self-determing factors home care services with tax deduction generated, their choice of using home care services with tax deduction seemed more appealing than publicly-financed home care services.

Different scandals around the globe during the past, in specific during the last decade, have intrigued the stakeholders to question the roles of both auditors and management. But most of the fingers since then have been raised on the role of auditors, because it is the auditors who are entrusted with the responsibility to detect any errors or frauds in the financial reports of the client-firm. Apart from this, the long-term auditor client relationship has been the center of attention in most of the discussions and debates as well. Numerous studies have been conducted by the academic researchers, financial and professional analysts, regulatory authorities and governing bodies, and in some cases by the auditors and the firms as well regarding the effects of long-term auditor-client relationship on audit quality, equity risk premium, financial reports quality, audit pricing etc. These studies provide us with different results, both with the positive and negative associations and effects of long-term auditor-client relationship on the basis of different factors and contexts. For long, auditing has been discussed in different studies and research areas but mostly in association with publicly listed companies. Less attention has been paid to the relationship of auditors and clients as far as clients in SMEs are concerned. In any country around the globe, SMEs are of major contribution in terms of backing the economy, giving it both the boost and the stability, as they collectively form the major chunk of the economy. If we specify our study to the SMEs in Sweden, then 99% of the enterprises in Sweden represent the SME sector; in addition they employ around 60% of the manpower. Based on these facts, and due to less attention given to auditor-client relationship in terms of SMEs, instead of; we have directed our concerns towards the study of effects of auditor-client relationship on audit quality in SMEs in this particular research study. In this study, we have opted for qualitative research with semi-structured interviews to be used as the tool for data collection. Interviews were conducted with two different groups of interviewees, one group representing the auditors and the other group representing the client-firms (SMEs). A total of seven interviews were conducted in order to strengthen and validate the results for our research question. Due to the limitations of this study, mostly in terms of cost and time, samples were selected from Umeå, Sweden. The data interview structure, data analysis and discussion, and conclusions were all made based on existing theories summarized in the theoretical review of this study. The results of this study suggests that (1) long-term audit tenure is beneficial for the audit quality if certain risk factors like risk of auditor independence and risk of developing complacency are controlled; and (2) factors such as NAS, industry specialization, knowledge and experience of the auditor, internal control in the client-firm, professional ethics, proper audit plan, providence of unbiased information by the client, and appointment of the auditor by the client-firm itself enhances the audit quality.

Till följd av det senaste decenniets företagsskandaler och kriser har diskussionen kring revisorns oberoende eskalerat. I och med finanskrisen 2008/09 har det påvisats att ett antal bolag ej erhållit oberoende granskning varför revisorns agerande har ifrågasatts. Eftersom det är av stor vikt att revisorn agerar objektivt och självständigt med avseende på tillförlitligheten till reviderad information diskuteras obligatorisk byrårotation som ett verktyg för att säkerställa revisorns oberoende. Syftet med studien är att undersöka hur obligatorisk byrårotation påverkar revisorns oberoende och vilka konsekvenser ett eventuellt införande av en dylik regel skulle innebära. Vidare behandlas byrårotations inverkan på den finansiella stabiliteten. Studien baseras på kvalitativ metod för att möjliggöra en djupgående förståelse för utvalda parters åsikter och synpunkter på en eventuell lagförändring. Intervjuer har genomförts med personer med stor inblick i revisionsbranschen. Studien visar att obligatorisk byrårotation skulle ha positiv inverkan på revisorns oberoende. Det följer av att byrårotation tros förhindra revisionsteamet att bli alltför bekant med revisionsklienten samt att revisorn anses mer oberoende då möjligheten till långvariga byråuppdrag är begränsad. Ett införande av byrårotation skulle medföra förbättrad revisionskvalitet trots påvisad kvalitetsnedgång i början på varje nytt revisionsuppdrag samt ökad revisionskostnad. Revisorns oberoende har betydelse för den finansiella stabiliteten men obligatorisk byrårotation skulle endast marginellt mildra eventuella framtida finansiella kriser.

Nyckelord: Revision, revisorers oberoende, fortsatt drift, Big 4, konsulttjänster och klientstorlek. Bakgrund: Under 2000-talet har den finansiella revisionen genomgått en rad förändringar. Detta till följd av ett antal händelser såsom Enronskandalen som kom att ifrågasätta revisorers oberoende ytterligare. Syfte: Studiens syfte är att undersöka huruvida en revisors oberoende påverkas av variabler som revisionsbyråns storlek (Big 4), konsulttjänster och klientstorlek. Metod: Utifrån en deduktiv ansats har vi använt en kvantitativ metod genom att analysera sekundärdata som vi hämtat från Affärsdatas databas. Urvalet bestod av årsredovisningar och dess tillhörande revisionsberättelser som studerats utifrån kriterierna: svenska aktiebolag som inlett konkurs under april, maj och december 2010. Studiens kvantitativa data har jämförts med tidigare forskning inom revisionsområdet, denna forskning bottnar i teorier kring agentteori och revision som försäkran. Resultat och slutsats: Studiens resultat visar att Big 4 anmärker i något större utsträckning än övriga revisionsbyråer kring fortsatt drift. Studien fann ett signifikant samband mellan Big 4 och konsulttjänster, företag som nyttjar revisionstjänster från Big 4 nyttjar konsulttjänster i högre utsträckning än företag som har annan revisionsbyrå. Klientstorlek har enbart en påverkan på företagens benägenhet att köpa konsulttjänster, det vill säga förekomsten av att även köpa konsulttjänster utöver revisionen ökar i takt med företagens storlek, om än inte signifikant. Sammanfattningsvis kan klargöras att ingen av de undersökta variablerna har någon signifikant inverkan på anmärkning kring fortsatt drift, varken enskilt eller tillsammans. Detta resultat gör att den rimligaste tolkningen blir att revisorerna förblir oberoende trots påverkan utifrån. Det mesta talar för att valet av revisionsbyrå, vilka tjänster som nyttjats eller vilket företag man representerar inte påverkar revisorns oberoende vilket visar på att revisorn tycks klara av sin uppgift som en tredje oberoende part. / Background: During the early 2000s the financial audit went through a series of changes. The cause of these changes were several, one of these reasons were the Enron scandal which arouse the question about the importance of auditor independence once again.  Purpose: The purpose of the study is to examine whether variables as Big 4, advisory services or client size has any influence on auditor independence. Method: From a deductive point of view a quantitative method has been used as we analyzed data collected from the database Affärsdata. The data were collected from annual reports and audit reports which were analyzed based on the following criteria: Swedish limited companies with a started bankruptcy process during April, May or December in the year 2010. The data of the study have been compared with previous research in the audit field which deals with the theories agency theory and audit as an affirmation. Results and conclusion: The results of the study shows that Big 4 firms tend to issue going concern opinions in a slightly higher extent than other audit firms. There is a significant association between Big 4 and advisory services. Companies who use audit services provided by a Big 4 firm also use their advisory services to a higher extent than those who use audit services from other audit firms. Client size does only show an association, even though it is not statistically significant, between those companies who use both audit and advisory services, in other words, the tendency of using both audit and advisory services increase with company size. None of the investigated variables had any significant affect on the tendency to issue a going concern opinion, neither individually nor together. The most reasonable explanation to these results comes down to the fact that the Swedish auditors are independent due to the variables we studied. Based on this we conclude that the choice of audit firm, weather companies use advisory services or not, or who you are, does not affect the auditor’s independence which indicates that auditors cope with the independence issues quite well.

In recent years, there has been a surge of research interest in the analysis of time series and spatial data. While on one hand more and more sophisticated models are being developed, on the other hand the resulting theory and estimation process has become more and more involved. This dissertation addresses the development of statistical inference procedures for data exhibiting dependencies of varied form and structure. In the first work, we consider estimation of the mean squared prediction error (MSPE) of the best linear predictor of (possibly) nonlinear functions of finitely many future observations in a stationary time series. We develop a resampling methodology for estimating the MSPE when the unknown parameters in the best linear predictor are estimated. Further, we propose a bias corrected MSPE estimator based on the bootstrap and establish its second order accuracy. Finite sample properties of the method are investigated through a simulation study. The next work considers nonparametric inference on spatial data. In this work the asymptotic distribution of the Discrete Fourier Transformation (DFT) of spatial data under pure and mixed increasing domain spatial asymptotic structures are studied under both deterministic and stochastic spatial sampling designs. The deterministic design is specified by a scaled version of the integer lattice in IRd while the data-sites under the stochastic spatial design are generated by a sequence of independent random vectors, with a possibly nonuniform density. A detailed account of the asymptotic joint distribution of the DFTs of the spatial data is given which, among other things, highlights the effects of the geometry of the sampling region and the spatial sampling density on the limit distribution. Further, it is shown that in both deterministic and stochastic design cases, for "asymptotically distant" frequencies, the DFTs are asymptotically independent, but this property may be destroyed if the frequencies are "asymptotically close". Some important implications of the main results are also given.
