Shelf biogeochemical interactions and feedback processes in the Benguela upwelling system
… biogeochemical interactions and their related feedback processes. The models are formulated differently but achieve similar objectives with respect to the physics and biogeochemistry. The BioEBUS model is used to simulate nitrogen processes under oxic and suboxic conditions in upwelling systems …

Towards an integrated model of feedforward-feedback processing in the visual cortex
… that will account for both feedforward and feedback processes in the ventral stream. We explore the plausibility of Bayesian network models for feedback. Our results show that although the resulting system under performs the original, it has a better rate of improvement as more and more …

Visuomotor adaptation in young adults with and without motor difficulties
… Recent studies suggested that presenting larger feedback improves the rate and extent of motor learning in healthy subjects and stroke patients. The present study recruited young adults with and without motor difficulties and aimed to examine their adaptability in visuomotor adaptation tasks with …

Principals & professional learning : a catalyst for transformational change
… five sub-themes emerged: resource allocation, feedback processes to support professional educator practice, instructional design for adult learning, student-centered outcomes, and the strengthening of systems supporting student learning. The principals, operating from diverse leadership …

The Consonant/Vowel Distinction: A Cognitive Difference Evidenced by Glides
… realized in the cognitive system largely through feedback processes. Evidence in support of this hypothesis comes from cross-linguistic and experimental data on glides, the most vowel-like consonants. The experimental results show differential patterns in the variances of articulatory and acoustic …

Properties of gas and dark matter in X-ray galaxy clusters with Sunyaev Zel'dovich measurements
… Tgas in order to constrain the non-gravitational processes which affect the thermal history of the gas. Furthermore I have studied the scaling relations between the X-ray quantities and Sunyaev Zel'dovich measurements. I have observed that X-ray laws are steeper than the relations predicted from …

Mode Choice Methodology in TRANSIMS
… choice methodology implemented by a series of feedback processes is proposed. However, it uses aggregate, deterministic mode choice model. There is little solid theoretic ground for the format and coefficients of the generalized costs used in the calibration process. The accessibility to a …

Annular mode-like responses to external forcings in a simple atmospheric general circulation model
… versus the response caused by changes in eddy feedback processes. The direct forcing alone is found to be insufficient to produce either the correct strength or shape of the annular mode patterns. Instead the changes in eddy fluxes must be included to produce the correct shape and amplitude of …

An evaluative study on attempts to improve the quality of processes for the U.S. Senate Productivity and Quality Award for Virginia
… Award for Virginia. This research reviews the processes used in determining winners for this award. Recommendations are made to improve the application evaluation and feedback processes, in particular. The thesis describes the types of key performance indicators that organizations report in …

Collaboration in recruitment and enrollment student communications
… to examine their experiences, perceptions, and processes relating to recruitment and enrollment student communications. The researcher performed three cycles of data analysis; in vivo coding, process coding, and theoretical coding. Findings, conclusions, and draft recommendations were reviewed …

Beyond Conscious Object Perception: Processing and Inhibition of the Groundside of a Figure
… hierarchy, with the latter arising from top-down feedback (Cacciamani, Scalf, & Peterson, submitted). Finally, I show that semantic information pertaining to the ground is accessed prior to the assignment of object status, but unlike shape information, is not suppressed (Cacciamani, Mojica, …

Top-down Modulation of the Chromatic VEP with Hypnotic Suggestion
… both bottom-up (stimulus driven) and top-down (feedback) processes. It has been demonstrated that directed spatial attention enhances processing of attended stimuli, inhibits non-attended stimuli, and increases baseline activity in portions of cortex corresponding to attended areas of the visual …

An Investigation Of Cloud Processes Relevant To Climate Sensitivity
… the Fourth Assessment Report of the IPCC, cloud feedbacks are the largest source of uncertainty in predicting the Earth's climate response to CO2 radiative forcing. Various global climate models estimate that this response amplifies the initial CO2 forcing by a factor between 2 and 5. The …

Evaluation and Application of the Community Land Model for Simulating Energy and Carbon Exchange in Agricultural Ecosystems
… and ecosystems, understanding biophysical feedback processes, and predicting future climate. Most state-of-the-art LSMs assessed in the fifth phase of the Coupled Model Inter-comparison project (CMIP5), however, did not include process-based crop models with comprehensive physiology and …

Explorations in musical tinkering
… map, are woven throughout this thesis. Loops are feedback processes. They range in scope from rapid iterative design, through interpersonal interaction and creative emergence, to longer-term personal transformation. Maps are active visualizations. We use them to externalize our thought processes, …

Ion Temperatures in Earth's Inner Magnetosphere: Ring Current Dynamics, Transient Effects, and Data-Model Comparisons
… which all exhibit unique plasma properties. The feedback processes between each region depend on geomagnetic activity levels and the preceding states of the solar wind and the respective magnetospheric regions. Of particular interest is understanding how ion temperatures evolve during …

Space-Time Experience in the Meta-Environment: A Cybersemiotic Analysis
… of such environments. It examines interactive processes among user, information, and interface; proposes a closer look at representational paradigms of space and time; suggests potentially illuminating parallels with complex adaptive systems; and explores their theoretical and practical …

Dynamics of naval ship design : a systems approach
… flow delays and approval delays) and feedback processes (design iteration, error propagation and design change.) Modeling of such mechanisms, using the methods of System Dynamics, provides a means to study past programs (in particular, the DDG-51Destroyer program of the 1980' s), and …
