<p> This dissertation consists of a scholarly edition of Bertrand Russell's letters to Helen Thomas Flexner and Lucy Martin Donnelly. Although Russell's reputation as a writer of voluminous letters is well-known, to date there are no collected editions of his personal correspondence. As an editorial project this thesis is very much concerned with the problematic and often controversial methods of editorial procedure. Another major concern is the assessment of a set of letters that span nearly half a century of riveting social upheaval.</p> <p>Russell's letters to Helen Flexner and Lucy Donnelly convey the personal and public sides of his life. The correspondence with them provides biographical information for the reader who is unfamiliar with Russell's life and thought as well as for the specialist. The letters, however, represent more than just an account of one man's life. As historical documents they recount major world events such as the Great War and discuss significant issues such as political elections and women's suffrage. Thus, in its scope, this thesis embraces various disciplines that reflect the multifarious aspects of Russell's activities and writings.</p> <p> Undoubtedly, the editor's role in the preparation and transformation of private documents to public ones is a crucial part of any editorial undertaking. The strategies employed in this edition involve techniques of selecting and presenting annotative material in the most comprehensive manner. The purpose of such notes is to provide the reader with a sense of the historical, sociological and literary themes in Russell's correspondence.</p> / Thesis / Doctor of Philosophy (PhD)

I denna uppsats undersöks om världshändelser skapar abnorma effekter hos oljebolags aktiekurser och om dessa effekter ter sig olika beroende på företagens olika storlek. Undersökningen utförs med hjälp av en eventstudie som genomförs på sex oljebolag med tre världshändelser som utgångspunkt. De valda världshändelserna bestod av två naturkatastrofer och en större ekonomisk händelse. Företagen som valdes delades in i två grupper om tre företag, där ena gruppen innehöll de större företagen och den andra gruppen de mindre. Slutsatserna som har kunnat dras av undersökningen är att händelserna i två av de tre undersökta fallen orsakade signifikanta abnorma under- eller överavkastningar hos oljebolagens aktier vilket bevisar en viss ineffektivitet hos marknaden. Det generella utfallet var att den ekonomiska händelsen visade sig ha en större påverkan på aktiekurserna än de två naturkatastroferna hade. Samtidigt kunde det påvisas en större skillnad mellan de större och de mindre företagens aktiekursers reaktioner gällande den ekonomiska händelsen. Resultaten visade att de mindre företagen drabbades hårdare. / This essay examines whether world events create abnormal effects of oil companies stock prices and whether these effects appear different depending on the companies’ different sizes. The analysis is performed using an event study conducted in six oil companies with three world events as a starting point. The selected world events consisted of two natural disasters and a greater economic event. The companies selected were divided into two groups of three companies, in which one group contained the larger companies and the second group the smaller ones. The conclusion that has been drawn from the study is that the events in two of the three cases studied caused significant abnormal deficit or excess returns of oil companies’ shares, which proves certain inefficiency of the market. The general outcome was that the economic event turned out to have a greater impact on the firms’ stock prices than the two natural disasters had. It was possible to distinguish a significant difference between the stock prices reactions of the larger and smaller firms regarding the economic event. The result showed that the smaller companies were affected to a larger extent.
