My dissertation investigates the social mechanisms that determine the allocation of consequences of earnings restatements for organizational elites, using a sample S&P1500 Index-listed firms restating earnings between 1997 and 2003. In chapter 1, I examine turnover following revelations of organizational misconduct. I find that outside director turnover is associated with...
In this dissertation, the Tg behavior of nanoconfined polymer films and 1-dimensional (1-D) patterned polymer nanostructures was studied. Using a novel fluorescence method, a reduction in Tg was observed upon confinement in PS films supported on silica, where free-surface (polymer-air interface) effects are dominant in modifying Tg. In contrast, Tg...
This study investigates the nature of the face-to-face interactions and collaborations between secondary school students and community members in the nested contexts of the classroom and a local Italian community, both situated in a large city in Canada. Students used the tools of inquiry of cultural ethnographers, interviewing members of...
Okilactomycin and chrolactomycin are antitumor antibiotics isolated in 1987 and 2001, respectively. These tetracyclic natural products possess a unique 6-5 fused tetrahydropyrone-butyrolactone. The spirocenter is part of a highly functionalized cyclohexene ring, which together with the aforementioned 6-5 system compose the core of these molecules. A six carbon, 1,3-dialkyl-substituted carbon...
This dissertation develops dynamic models to examine markets with product differentiation where both firm conduct and consumer behavior is jointly influenced by switching costs, network effects and technological innovation. In Chapter 1 I propose a structural model of competition where firms set prices, introduce new products and scrap obsolete models....
Metal oxide surfaces are generally recognized as active substrates for many catalytic reactions. Density Functional Theory (DFT) has been found as a useful computational tool to investigate the geometry, energy, electronic structure of reactive oxide surfaces and their interaction with small molecules and fragments. In this thesis, primary efforts have...
Cluster Analysis deals with classifying a sample of multivariate measurements into different categories. In this dissertation we study the effect of the correlation structure of the data on the performance of a clustering method. We begin with the analysis of two-component normal mixture models and then proceed to cluster analysis...
Constructing 3D objects from 2D images has been an active research area for decades. Given captured 2D information from various devices, different techniques were developed to assign 3D positions to the target object. However, methods for reconstructing a 3D model from a single 2D image remain largely manual and labor-intensive....
First published in German in 1940 and widely recognized as a classic of philosophical anthropology, Laughing and Crying considers this significant pair of types of expressive behavior, considering them both in themselves and in their relation to the fundamental nature of humanity.
First published in German in 1917, On Emotional Presentation investigates the interrelation of emotions, values, and obligation. Alexius Meinong presents a realist theory of values in which values are given in and through emotion but are also ontologically independent of emotion or any subjective attitude. Meinongs first discusses the concept...
