In this work, through investigating a series of liquid, glassy, and crystalline samples with ultrafast multiple-mode 2D IR and IR transient absorption methods, we demonstrated that the signal anisotropy of vibrational relaxation-induced heat effects is determined by both relative molecular orientations and molecular rotations. If the relative molecular orientations are randomized or molecular r...

Given a graph G, the acyclic orientation graph of G, denoted AO(G), is the graph whose vertices are the acyclic orientations of G, and two acyclic orientations are joined by an edge in AO(G) iff they differ by the reversal of a single edge. A hamilton cycle in AO(G) gives a Gray code listing of the acyclic orientations of G. We prove that for certain graphs G, AO(G) is hamiltonian, and give exp...

We propose models for semantic orientations of phrases as well as classification methods based on the models. Although each phrase consists of multiple words, the semantic orientation of the phrase is not a mere sum of the orientations of the component words. Some words can invert the orientation. In order to capture the property of such phrases, we introduce latent variables into the models. T...

The common perception is that all types of work and work organizations appear to involve knowledge: knowledge intensive work, knowledge workers, knowledge products, customerrelated knowledge and knowledge intensive organizations. Therefore, as organizations increasingly organize their activities in the form of projects, effective ways of knowledge management are needed to deliver successful and...

st-orientations (st-numberings) or bipolar orientations of undirected graphs are central to many graph algorithms and applications. Several algorithms have been proposed in the past to compute an st-orientation of a biconnected graph. In this paper, we present new algorithms that compute such orientations with certain (parameterized) characteristics in the final st-oriented graph, such as the l...

Most retinal ganglion cells (Levick and Thibos, 1982) and cortical cells (Leventhal, 1983; Leventhal et al., 1984) subserving peripheral vision respond best to stimuli that are oriented radially, i.e., like the spokes of a wheel with the area centralis at the hub. We have extended this work by comparing directly the distributions of orientations represented in topographically corresponding regi...

Title of Dissertation: ACHIEVEMENT GOAL ORIENTATIONS IN PHYSICAL REHABILITATION Sonia Kristi Lawson, Doctor of Philosophy, 2005 Dissertation directed by: Professor Patricia Alexander, PhD Department of Human Development Goals are used extensively in physical rehabilitation medicine to measure success. However, the goal construct has been given very little attention in research as compared to th...

Using cross-sectional and longitudinal data from expatriates in China, the authors investigated the roles of general, work, and interaction adjustment, as well as work stress, as mediators between the antecedents (learning, proving, and avoiding goal orientations, and perceived organizational support) and expatriate outcome (job performance and premature return intention) relationships. Results...
