Managing Credit Risk: Assessing the Probability of Corporate Bankruptcy using Quantitative Risk Analysis

Managing credit risk might be the single most important business area for any commercial bank. The assessment of "good" and "bad" corporate clients is a important task for a creditor. A bad debtor is a corporate client with hardships in meeting the continous claims (interest payments) that a creditor requires. One way of evaluating or separating a "bad" client from a "good" client is to assess the propensity for the client to file for bankruptcy. This thesis examines 226 firms in the Swedsh market in the quest of predicting corporate bankruptcy.

Comparison of two methods for evolving recurrent artificial neural networks for

n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of sensor range.

Analys av ljudspektroskopisignaler med artificiella neurala eller bayesiska nätverk

Vid analys av fluider med akustisk spektroskopi finns ett behov av att finna multivariata metoder för att utifrån akustiska spektra prediktera storheter såsom viskositet och densitet. Användning av artificiella neurala nätverk och bayesiska nätverk för detta syfte utreds genom teoretiska och praktiska undersökningar. Förbehandling och uppdelning av data samt en handfull linjära och olinjära multivariata analysmetoder beskrivs och implementeras. Prediktionsfelen för de olika metoderna jämförs och PLS (Partial Least Squares) framstår som den starkaste kandidaten för att prediktera de sökta storheterna..

Variationer i normal språklig förmåga hos vuxna jämfört med neural aktivitet

Since the brain is an important prerequisite for human language there is a great interest to gain more knowledge about healthy brain activity during language mediated communication. This study examines variations in high level language ability relating to demographic factors like gender and age and relates language ability to neural activity.Eighteen individuals in ages between 22 and 64 were included and divided into groups in relation to gender and age. The material used to assess language ability was derived from Testbatteri för Bedömning av Subtila Språkstörningar (Laakso, Brunnegård, Hartelius & Ahlsén, 2000), Swedish Lexical Decision Test (Almkvist, Adveen, Henning & Tallberg, 2007) and a reading test (Högskoleprovet). The results were correlated with measured brain activity using functional Magnetic Resonance Imaging (fMRI) and language paradigms. ANOVA was applied to discover possible demographic variances in language ability as well as in brain activity.The results showed no significant differences in language ability.

Nätverkens betydelse för turistdestinationen : en studie av gotländska turistrelaterade nätverk

The tourism industry is growing and with its growth competition between destinations rises. In competition, cooperation and collaboration between tourism operators seem beneficial when creating an attractive and dynamic tourist destination.The purpose of this study is to describe and discuss the significance and influence of tourist related networks at a tourist destination, and therefore this study aims to examine the question: What significance do the tourist related networks have at a tourist destination?This study focuses on seven networks on Gotland that are tourism related, and the representatives of the networks were interviewed in order to get their view on the network and its significance to the destination. The study shows that networks have an important role in creating a unified tourist product of the destination, and in reaching out to the potential visitors through joint destination marketing. The study also shows that the tourism related networks helps to improve the reception of the tourist at a destination and to secure the quality of the tourist destination and its tourist products..

Från blogginlägg till nyhet : ???????En kvantitativ studie om hur journalister använder sociala nätverk för att hitta nyheter

The aim of our study was to examine how Swedish journalists use the three social networks Facebook, Twitter and blogs to find news. We wanted to study which group of journalists that were using these networks most frequently and why. We also wanted to find out which of the three networks they use the most.We made a questionnaire which we sent out by e-mail to 400 Swedish journalists. 215 of them participated in our study.We analyzed the results of the responses from the questionnaire and discussed patterns and relations between them.The study establishes that the majority of the respondents believe that the networks are very useful and effective in their work.Our results show that out of the three social networks the journalists who participated in our study prefer to use blogs as sources in their line of work, as they are full of information from individuals and contain unique facts and stories.Alongside the results we discussed how social networks might be used in the future of journalism. Most of the respondents are aware of the possibility that they may need to increase the usage of them eventually, and that they will be an important part of the journalistic work process in the future. .

Fysisk och numerisk modellering av flödesmönster i utjämningsmagasin med öar

The major aim of the thesis is to describe the networks, relations and marketing of some university libraries and their customers in the year 2000. I illustrate how these issues interact and whether they have changed due to the recent development of technology and if so, how. The thesis is based on interviews with two directors of libraries and two librarians at two different libraries. A small survey with 16 questionnaires has also been performed in order to get a more general view on librarians' opinions in these questions. The thesis mainly shows that the networks in which the respondents take part primarily exist in the library sphere and towards the universities.

Tillit i moldavien

Moldova is one of Europe?s poorest countries with a struggling business environment and an unpredictable political situation. The purpose of this thesis is to understand the implications of corruptions and why networks have come to play a key role in the Moldovan culture and if the formations of network are due to heritage or an effect of functionalism. The focus of the study is also to explain how the networks develop and the formation and maintenance of loyalty and trust among the members of the network. The study is of a qualitative nature that uses a key informant sampling method to get access to members of different business networks.
