1. 1. Information and financial markets

   Författare :Stefan Anchev; Jörgen Hellström; Rickard Olsson; Juha-Pekka Kallunki; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Information; dissemination of information; production of private information; information disadvantage; investor base; stock return anomalies; stock price informativeness; quantity of firm disclosure; less sophisticated individual investors;

   Sammanfattning : The results in this thesis are consistent with the hypotheses that: 1) the incomplete dissemination of information across investors helps in explaining the occurrence and the persistence of cross-sectional stock return anomalies, 2) the properties of the investor base of a stock have implications for the informativeness of the stock's price and 3) a greater quantity of firm disclosure places less sophisticated investors at an information disadvantage. Overall, the thesis provides new empirical evidence about the role of information in financial markets. LÄS MER

3. 2. Predictive Techniques and Methods for Decision Support in Situations with Poor Data Quality

   Författare :Rikard König; Högskolan i Skövde; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Rule Extraction; Genetic Programming; Uncertainty estimation; Machine Learning; Artificial Neural Networks; Data Mining; Information Fusion; Information technology; Informationsteknik; Teknik; Technology;

   Sammanfattning : Today, decision support systems based on predictive modeling are becoming more common, since organizations often collect more data than decision makers can handle manually. Predictive models are used to find potentially valuable patterns in the data, or to predict the outcome of some event. LÄS MER

   Sammanfattning : Youth Crime, Community Service and Labor Market OutcomesCan lifetime trajectories of youth offenders be improved through criminal justice policy? I evaluate the effects of a youth justice reform in Sweden that sharply increased the share of juveniles assigned to court-ordered community service --- i.e. unpaid, low-skilled work. LÄS MER

5. 4. Imprecise information in multi-level decision trees

   Författare :Jim Johansson [Idefeldt]; Love Ekenberg; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multi-level; decision tree; decision analysis; decision tool; imprecise; Computer science; Datavetenskap;

   Sammanfattning : The information available to decision makers is often vague and imprecise, and various methods based on interval estimates of probabilities and utilities have been proposed to deal with this. The discussion has, however, mostly evolved around representation, and much less has been done to take into consideration the evaluation, and also computational and implementation aspects has been left out.

7. 5. Frequency Transfer Techniques and Applications in Fiber Optic Communication Systems

   Författare :Sven-Christian Ebenhag; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronous digital hierarchy SDH ; UTC; synchronization; Time transfer; optical fiber; optical fiber network; GPS carrier phase; global positioning system GPS ; synchronous optical networking SONET ;

   Sammanfattning : Modern society is dependent on communications and the developments of these increases constantly through a seemingly endless demand for communication services and thereby synchronization and time. This is confirmed by a vast range of research on communications, irrespective of technology and protocol. LÄS MER
