A Sequential Algorithm For Biological Event Detection Using Statistical Nonstationarity, John Dicecco

Open Access Dissertations

High dimension complex dynamical systems, such as those found in physiological processes, produce time series which are often accompanied by nonstationarity. In many cases, the nonstationarity is caused by a physiologically significant event such as the prelude to ventricular fibrillation in cardiac arrest or the change of stasis by introducing pharmaceuticals. A need exists to be able to detect and monitor this change. Most conventional attempts at addressing this problem involve segmenting the time series and evaluating the statistics of the segments. The difficulty with this approach is that the nature of the nonstationarity can be transient, such that it …

An Examination Of Price In The Economic Management Of Marine Resources: Three Empirical Essays, Diego Valderrama Rojas

Open Access Dissertations

This dissertation conducts an examination of price as an economic parameter of strategic importance for the improved management of marine resources. To this end, the dissertation examines three different problems in marine resource economics: the effectiveness of rotational management strategies in the Atlantic sea scallop fishery; the implications of market interactions with the aquaculture sector for Alaskan salmon fisheries; and the effectiveness of targeted tariffs in the 2004 shrimp antidumping case. Each of these studies tackles a number of management issues of current relevance for U.S. fisheries. In each case, economic analysis leads to a better understanding of the concept …

Truncated Toeplitz Operators On Finite Dimensional Spaces, William T. Ross, Joseph A. Cima, Warren R. Wogen

Department of Math & Statistics Faculty Publications

In this paper, we study the matrix representations of compressions of Toeplitz operators to the finite dimensional model spaces H²ƟBH², where B is a finite Blaschke product. In particular, we determine necessary and sufficient conditions - in terms of the matrix representation - of when a linear transformation on H²ƟBH² is the compression of a Toeplitz operator. This result complements a related result of Sarason [6].

Cold Nuclear Matter Effects On J/Ψ Production As Constrained By Deuteron-Gold Measurements At Snn=200 Gev, Andrew Marshall Adare, Gyöngyi Baksay, László A. Baksay, Klaus Dehmelt, Marcus Hohlmann, S. Rembeczki, Phenix Collaboration

Aerospace, Physics, and Space Science Faculty Publications

We present a new analysis of J/ψ production yields in deuteron-gold collisions at √sNN=200 GeV using data taken from the PHENIX experiment in 2003 and previously published in S. S. Adler et al. [Phys. Rev. Lett 96, 012304 (2006)]. The high statistics proton-proton J/ψ data taken in 2005 are used to improve the baseline measurement and thus construct updated cold nuclear matter modification factors (RdAu). A suppression of J/ψ in cold nuclear matter is observed as one goes forward in rapidity (in the deuteron-going direction), corresponding to a region more sensitive to initial-state low-ₓ gluons in the gold nucleus. The …

Constraining Convection Parameters From The Light Curve Shapes Of Pulsating White Dwarf Stars: The Cases Of Ec 14012-1446 And Wd 1524-0030, Gerald Handler, Judith L. Provençal, Michael H. Montgomery, Encarni Romero-Colmenero, Kaushar Sanchawala, Monika A. Lendl, Matt A. Wood, Isaac M. Silver, Paul G. Beck, Wenping Chen

Aerospace, Physics, and Space Science Faculty Publications

Montgomery [1] developed a method to probe convection in pulsating white dwarf stars which allows the recovery of the thermal response time of the convection zone by fitting observed non sinusoidal light curves. He applied this method to two objects; the Whole Earth Telescope (WET) observed the pulsating DB white dwarf GD 358 for just this purpose. Given this WET run's success, it is time to extend Montgomery's method to pulsating DA white dwarf (ZZ Ceti) stars. We present observations of two ZZ Ceti stars, WD 1524 - 0030 and EC 14012 - 1446, both observed from multiple sites. EC …

Evaluation Of The Long-Term Impact Of The Tostan Programme On The Abandonment Of Fgm/C And Early Marriage: Results From A Qualitative Study In Senegal, Nafissatou J. Diop, Amadou Moreau, Helene Benga

Reproductive Health

In 1998–99, a village empowerment program was implemented in the Thiès/Fatick and Kolda regions of Senegal by the nongovernmental organization Tostan, to mobilize communities to hold public declarations in support of abandoning harmful traditional practices, including female genital mutilation/cutting (FGM/C) and child marriage. The information presented in this report indicates that many did end the practices following a public declaration, however, the lack of follow-up in the field and the absence of support mechanisms pose a large obstacle. Nevertheless, the program achieved significant results: knowledge of life skills resulting in positive changes and a shift in the perception of FGM/C …

The Development Of Pre-Service Teachers’ Technology Specific Pedagogy, Rachel Harrington

Faculty Publications - College of Education

The purpose of this study was to document the development of pre-service teachers’ Technology Specific Pedagogy as they learned to teach mathematics with technology during their initial licensure program. The study investigated the pre-service teachers’ learning using both a social and a psychological perspective of teacher learning. Two research questions were used to guide the research:

1. What patterns of participation are displayed across learning contexts as pre-service teachers reason pedagogically about teaching mathematics with technology prior to their full-time student teaching?
2. In what ways do the Technology Partnership Project and its features facilitate pre-service mathematics teachers’ development of TPCK?

Evaluation Of The Algorithms And Parameterizations For Ground Thawing And Freezing Simulation In Permafrost Regions, Yinsou Zhang, Sean K. Carey, William L. Quinton

Geography and Environmental Studies Faculty Publications

Ground thawing and freezing depths (GTFDs) strongly influence the hydrology and energy balances of permafrost regions. Current methods to simulate GTFD differ in algorithm type, soil parameterization, representation of latent heat, and unfrozen water content. In this study, five algorithms (one semiempirical, two analytical, and two numerical), three soil thermal conductivity parameterizations, and three unfrozen water parameterizations were evaluated against detailed field measurements at four field sites in Canada’s discontinuous permafrost region. Key findings include: (1) de Vries’ parameterization is recommended to determine the thermal conductivity in permafrost soils; (2) the three unfrozen water parameterization methods exhibited little difference in …

Predictors Of Outcome For Non-Traumatic Intracerebral Hemorrhage, Syed A. Jamil, Abdul S. Khan, Zekeriya Akturk

Neurosciences

OBJECTIVE: To evaluate the prognosis, neurologic outcome, and predictors of survival in patients with non-traumatic intracerebral hemorrhage. METHODS: We evaluated prospectively a cohort of 96 Saudi adult males and females with stroke during the month of July 2005 at Arar Central Hospital, Riyadh, Kingdom of Saudi Arabia. Out of 103 patients, 96 patients, who were diagnosed as having intracerebral hemorrhage (ICH) presenting to the emergency department for initial evaluation, were included, except those with recurrent intracerebral hemorrhage, arteriovenous malformation, subarachnoid hemorrhage, traumatic brain injury, hemorrhagic infarctions, and patients receiving anticoagulant therapy. No patient underwent any neurosurgical procedure. RESULTS: The results …
