The Impact of Unions on Information Asymmetry
… calculated using industry-level union data, and information asymmetry. Prior literature also finds a mitigating effect from employee ownership on the negative association between union power and voluntary disclosure. Using a sample of company observations for fiscal years 2008 through 2010, I …

ΣΥΜΒΟΛΗ ΣΤΗ ΣΤΑΤΙΣΤΙΚΗ ΘΕΩΡΙΑ ΠΛΗΡΟΦΟΡΙΩΝ
THERE ARE SEVERAL MEASURES OF INFORMATION (M.O.I) WHICH ARE USED FOR VARIOUS PURPOSES AND WITHIN DIFFERENT CONTEXTS IN STATISTICS AND RELATED FIELDS. THE MOSTWELL KNOWN MEASURES ARE THOSE OF FISHER, KULLBACK-LEIBLER, RENYI AND SHANNON. THE M.O.I. ARE FOUNDED BY THE PROPERTIES WHICH THEY SATISFY. …

Contextual Effects in Tax Research: An Experimental Investigation of Adaptivity and Expert Performance in an Information Search Task
Based on a detailed analysis of the two tax decision-making contexts, planning and compliance, I predict that tax practitioners who know that the contexts differ in particular ways will conduct broader information search in planning than in compliance. I also predict that the nature of the decision …

Chaos and Thermalization in Quantum Many-Body Systems and Gravity
In this thesis, we explore the process of thermalization in chaotic quantum many-body systems with the help of concepts and techniques from quantum information theory. We identify a universal dynamical process in the Heisenberg evolution of operators known as void formation, and use it to provide a …

Information system success and its association with user attitude, belief and involvement
The motivation for this research was twofold. The first was to explore measures of information system success. The second, to investigate the influence of user variables, specifically attitude, belief and levels of user involvement, on information system success. Although researchers agree that the …

Network Dynamics of Visual Naming
<p>Recognition and naming of objects and actions are fundamental components of language. They involve several different systems working in coordination to accomplish a complex behavior. During visual naming, sensory and semantic processing are carried out by dedicated cortical substrates in the …

The Relationships Among Age, Physical Activity, and Working Memory
… ages, determining exogenous factors that may offset cognitive decline become increasingly important. The primary goal of the present study was to determine whether older individuals who engage in regular physical activity demonstrate superior working memory performance relative to older …

Two Essays on the Probability of Informed Trading
This dissertation consists of two essays. The first essay develops a new methodology for estimating the probability of informed trading from the observed quotes and depths, by extending the Copeland and Galai (1983) model. This measure (PROBINF) can be computed for each quote and it represents the …

Realising context-oriented information filtering.
The notion of information overload is an increasing factor in modern information service environments where information is ‘pushed’ to the user. As increasing volumes of information are presented to computing users in the form of email, web sites, instant messaging and news feeds, there is a …

Towards reliable organisms: fault-tolerance in unconventional models of computation
Computation is often described in abstract and idealized terms. In this setting, the details of the computer can be neglected: different models of computation are interchangeable for a cost which is at most polynomial in the size of the task at hand. The situation is more complicated for computers …

Point process based high frequency volatility estimation : theory and applications
This thesis is a compilation of three main studies with the common theme: point process based high-frequency volatility estimation. The first chapter introduces a new class of high-frequency volatility estimators and examines its asymptotic properties. The second chapter studies the relative …
