Protein-DNA Binding: Discovering Motifs and Distinguishing Direct from Indirect Interactions
… DNA replication, is regulated largely through interactions between proteins or protein complexes and DNA. Although a lot is known about the interacting proteins and their role in regulating transcription and replication, the specific DNA binding motifs of many regulatory proteins and complexes …

Contemporary Network Theory: Concepts and Implications for Transportation Asset Management
… the agents of the network, their direct and indirect interactions among each other, and their importance as elements of a complex network, and utilizes these data to support transportation asset management. The methodology consist of seven steps: (1) define the networks of interest; (2) …

Understanding nonresidential fathers’ involvement in their children’s education : a qualitative approach
… and activities with their children, and through indirect interactions with the school and the co-parent. Results suggest implications for future research, child and family policy, schools, and health-practitioners.

Distances Between Species in Food Webs: Evaluating Alternative Metrics' Predictive Power
… of another. Complex systems of species’ interactions can be described as ecological networks. One way in which ecological networks can give information concerning one species’ response to the perturbation of another is through the quantification of species’ proximity to one another in the …

Effects of prey distribution on resource defense, foraging behavior, and growth in stream-dwelling Arctic char (Salvelinus alpinus)
… distribution of critical resources, ranging from indirect interactions during resource depletion (i.e., exploitative competition) to direct attacks and monopolization (i.e., interference competition). Spatial distribution of drifting prey provides a unique form of resource heterogeneity that may …

Dealing with risk in business networks : the use of institutional devices
… a relevant ontological understanding of business interactions, this thesis draws on institutional research to explain how companies use institutional devices, including industry standards, General Terms and Conditions and framework contracts, for dealing with risk at three interdependent levels of …

First principles study of structure, defects and proton insertion in MnO₂
… migration due to Jahn-Teller distortion and H-H interactions. Results indicate that direct H-H interactions are not that significant compared to oxygen mediated indirect interactions, observed in manganite. Experimental and calculated ramsdellite discharge curves deviate significantly at the …

Interacting Beliefs and Processes in Mothers of Children Diagnosed with Autism
… methods were used to expand the exploration of interactions beyond just the domain of beliefs to the entire process. In other words, the qualitative strand of this study aimed to determine if the self-regulation process occurred in MCDAs, and if so, how? Most of the results of the quantitative …

Multi-faceted analyses of plant-pollinator interactions: From ecological communities to individual foraging decisions
… be fully understood without the direct and indirect interactions it has with the rest of its community and environment. Therefore, it is crucial to understand how behavior and species interactions influence ecosystems at multiple scales – from ecosystem functions to individual decisions. I …

Interaction of tomato plants infected by the nematode Meloidogyne javanica on aboveground herbivore Tetranychus urticae and on behaviour of its predator Phytoseiulus macropilis
Tritrophic interactions play an important role in the dynamics of arthropods with their hosts. By inducing defenses, plants respond to herbivore attacks, may affect your development. The general objective of this research was to investigate the effect of the nematode Meloidogyne javanica on the …

Using patchy plant invasions to understand how diffuse interactions modify facilitation and competition
<p>Indirect interactions among plants promote conditionality in competitive outcomes that affect plant community structure and function. I utilized spatially patchy distributions of two invasive exotic plants, <i>Centaurea stoebe</i> and <i>Bromus tectorum</i>, to explore conditionality in plant …

THERMODYNAMIC PROPERTIES OF THE UNFOLDED ENSEMBLE OF PROTEINS
… by its excluded volume, and net energetic interactions with its environment, has served as a representation of the unfolded ensemble of proteins. The work in this thesis involves equilibrium, nuclear magnetic resonance and time-resolved kinetics spectroscopic studies on the unfolded …

Quantifying and Simulating Fine-Scale Spatial Patterns in Plant Populations
… patterns are largely determined by direct and indirect interactions between plants and their immediate neighbors. Such interactions thus play an important role in the structure and function of plant communities. Study of these types of local interactions has greatly benefitted from simulation …

Interplay between competition and evolution in invaded and native plant communities
… our understanding of ecological and evolutionary interactions is growing, so far little is known about how competition among plants interacts with evolution to shape communities. In my dissertation, I use species invasions to investigate the evolutionary and ecological consequences of plant …

Speeding up electrostatic computations for molecular dynamics
… and (2) calculating long range electrostatic interactions during the simulation. Presented here are two novel methods, the <i>direct interaction approximation (DIA)</i> and the <i>hierarchical charge partitioning (HCP) approximation</i>, for speeding up each of these two computations. The …

Foraging ecology of two piscivores in woody habitat and effects of their introduction on lake ecosystems
… need to test the generality of cascading trophic interactions in these lower latitude lentic ecosystems. Thus, in chapter 1 I tested for the effects of supplemental piscivore enhancements on the food webs of several Illinois lakes in a series of whole-lake experiments incorporating unmanipulated …
