Redox non-innoence permits catalytic nitrene carbonylation by (dadi)Ti=NAd (Ad = adamantyl)

Description: This article describes (dadi)Ti(X/L) species that manifest redox non-innocence (RNI), including a rare instance in which carbon monoxide does not affect redox activity at the metal, and does not bind, thus permitting its use as a substrate in catalysis.

Loss of Innocence

Description: Loss of Innocence uses sculpture, two-dimensional imagery, and text to explore the moment when children lose their innocence or realize their mortality. In the introduction, I explain that there are many factors, such as age and personality, which determine how children will deal with traumatic events in their lives and the duration of time that must pass before they move past the event. Often, children will combine childhood fantasy with random facts to create their own satisfactory explanation of what has happened. In my problem in lieu of thesis, I discuss work that I created with these thoughts in mind. I explore how the sculpture, two-dimensional imagery, and text work together to convey the emotion of innocence lost.

Source Analysis of the Crandall Canyon, Utah, Mine Collapse

Description: Analysis of seismograms from a magnitude 3.9 seismic event on August 6, 2007 in central Utah reveals an anomalous radiation pattern that is contrary to that expected for a tectonic earthquake, and which is dominated by an implosive component. The results show the seismic event is best modeled as a shallow underground collapse. Interestingly, large transverse surface waves require a smaller additional non-collapse source component that represents either faulting in the rocks above the mine workings or deformation of the medium surrounding the mine.

National Gaming Day: Planning a successful gaming event

Description: This presentation discusses the American Library Association's (ALA's) National Gaming Day @ your library, a fairly new event created to promote the "educational, recreational, and social value of all types of games". The University of North Texas (UNT) Library has participated for two years and has organized their event to offer fun along with a focus on research and development opportunities available for people interested in all aspects of gaming. In this presentation, the authors detail the planning and organization of National Gaming Day at an academic library.

Power system extreme event screening using graphpartitioning

Description: We propose a partitioning problem in a power system contextthat weighs the two objectives of minimizing cuts between partitions andmaximizing the power imbalance between partitions. We then pose theproblem in a purely graph theoretic sense. We offer an approximatesolution through relaxation of the integer problem and suggest refinementusing stochastic methods. Results are presented for the IEEE 30-bus and118-bus electric power systems.

Effects of Monitoring Positive and Negative Events on Measures of Depression

Description: This study examined psychoanalytic, physiological, and social learning models of depression in terms of etiology and symptomatology. Emphasis was placed on social learning theories of depression. First, Beck's cognitive approach stated that the root of depression was a negative cognitive set. Depressive episodes might be externally precipitated, but it was the individual's perception and appraisal of the event that rendered it depression inducing. Secondly, Seligman's learned helplessness model explained reactive depression in terms of a belief in one's own helplessness. Specifically, Seligman stated belief in the uncontrollability of outcomes resulted in depression, irrespective of the correspondence of such beliefs to objective circumstances. Additionally, depression resulted from noncontingent aversive stimulation and noncontingent positive reinforcement. Thirdly, Lewinsohn's model was based on these assumptions: a low rate of response-contingent positive reinforcement which acted as an eliciting stimulus for depressive behaviors. This low rate of response-contingent positive reinforcement constituted an explanation for the low rate of behaviors observed in the depressive. Total amount of response—contingent positive reinforcement is a function of a number of events reinforcing for the individual, availability of reinforcement in the environment, and social skills of the individual that are necessary to elicit reinforcement.

Integrated Seismic Event Detection and Location by Advanced Array Processing

Description: The principal objective of this two-year study is to develop and test a new advanced, automatic approach to seismic detection/location using array processing. We address a strategy to obtain significantly improved precision in the location of low-magnitude events compared with current fully-automatic approaches, combined with a low false alarm rate. We have developed and evaluated a prototype automatic system which uses as a basis regional array processing with fixed, carefully calibrated, site-specific parameters in conjuction with improved automatic phase onset time estimation. We have in parallel developed tools for Matched Field Processing for optimized detection and source-region identification of seismic signals. This narrow-band procedure aims to mitigate some of the causes of difficulty encountered using the standard array processing system, specifically complicated source-time histories of seismic events and shortcomings in the plane-wave approximation for seismic phase arrivals at regional arrays.

Annual Hanford Seismic Report for Fiscal Year 2007

Description: This annual report documents the locations, magnitudes, and geologic interpretations of earthquakes recorded for the Hanford monitoring region of south-central Washington in fiscal year 2007 (October 2006 through September 2007). The report provides summaries of seismic events recorded during the first three quarters of fiscal year 2007 and contains a more comprehensive discussion of seismic events for the fourth quarter of the fiscal year.

Seismic Moment Tensor Report for the 06 Aug 2007, M3.9 Seismic Event in Central Utah

Description: We have performed a complete moment tensor analysis (Minson and Dreger, 2007) of the seismic event, which occurred on Monday August 6, 2007 at 08:48:40 UTC, 21 km from Mount Pleasant, Utah. The purpose of this report is to present our scientific results, making them available to other researchers working on seismic source determination problems, and source type identification. In our analysis we used complete, three-component seismic records recorded by stations operated by the USGS, the University of Utah and EarthScope. The results of our analysis show that most of the seismic wave energy is consistent with an underground collapse, however the cause of the mine collapse is still unknown.
