Spatial Skills As Predictors Of Success In First-Year Engineering, Sheryl Sorby, Edmund Nevin, Avril Behan, Eileen Mageean, Sarah Sheridan

Conference papers

Numerous research studies have highlighted the importance of well-developed 3-D spatial skills for success in STEM related programs. Poor spatial skills, particularly among first-year students, can place them at a distinct disadvantage when completing introductory courses in mathematics, CAD, descriptive geometry, and graphic communications - first-year requirements in many STEM related programs. This in turn can lead to poor grades and retention issues. Women are disproportionally among the group of students with weak or poorly developed 3-D spatial skills meaning that they are at a greater risk of leaving engineering when compared to their male counterparts. In this study, the …

Enhanced Precision In The Analysis Of Randomized Trials With Ordinal Outcomes, Iván Díaz, Elizabeth Colantuoni, Michael Rosenblum

Johns Hopkins University, Dept. of Biostatistics Working Papers

We present a general method for estimating the effect of a treatment on an ordinal outcome in randomized trials. The method is robust in that it does not rely on the proportional odds assumption. Our estimator leverages information in prognostic baseline variables, and has all of the following properties: (i) it is consistent; (ii) it is locally efficient; (iii) it is guaranteed to match or improve the precision of the standard, unadjusted estimator. To the best of our knowledge, this is the first estimator of the causal relation between a treatment and an ordinal outcome to satisfy these properties. We …

Pre-Breakdown Arcing And Electrostatic Discharge In Dielectrics Under High Dc Electric Field Stress, Allen Andersen, Jr Dennison

Journal Articles

Highly disordered insulating materials exposed to high electric fields will, over time, degrade and fail, potentially causing catastrophic damage to devices. Step-up to electrostatic discharge (ESD) tests were performed for two common polymer dielectrics, low density polyethylene and polyimide. Pre-breakdown transient current spikes or arcs were observed, using both slow and high speed detection. These pre-ESD discharge phenomena are explained in terms of breakdown modes and defect generation on a microscopic scale. The field at which pre-breakdown arcing begins was compared to the onset field for electrostatic discharge at which complete breakdown occurs for each material studied. We present evidence …

Revisiting The Vanishing Refuge Model Of Diversification, Robert Damasceno, Maria L. Strangas, Ana C. Carnaval, Miguel T. Rodrigues, Craig Moritz

Publications and Research

Much of the debate around speciation and historical biogeography has focused on the role of stabilizing selection on the physiological (abiotic) niche, emphasizing how isolation and vicariance, when associated with niche conservatism, may drive tropical speciation. Yet, recent re-emphasis on the ecological dimensions of speciation points to a more prominent role of divergent selection in driving genetic, phenotypic, and niche divergence. The vanishing refuge model (VRM), first described by Vanzolini and Williams (1981), describes a process of diversification through climate-driven habitat fragmentation and exposure to new environments, integrating both vicariance and divergent selection. This model suggests that dynamic climates and …

Distribution Of Dissolved Trace Metals And Carbon System Parameters In The Surface Waters Of The Hillsborough River And Tampa Bay, Matthew Matthias Elliott

USF Tampa Graduate Theses and Dissertations

This work represents a first look at the general spatial distribution of trace metals and the inorganic carbon system in the surface waters of Tampa Bay. Tampa Bay's chemical environment bears many influences ranging from hydrological and geological to anthropogenic and meteorological. A large y-shaped estuary on the west-central side of the Florida Peninsula, Tampa Bay extends over 400 square miles and has a 2200 square mile watershed that includes extensive swamps, scrub, agricultural lands and densely urbanized areas. Reaching 37 miles from the northernmost point of Old Tampa Bay to the mouth of the estuary near the Sunshine Skyway …

The Brightest Cluster Galaxy In Abell 85: The Largest Core Known So Far, O. López-Cruz, C. Añorve, M. Birkinshaw, D. M. Worrall, H. J. Ibarra-Medel, Wayne A. Barkhouse, J. P. Torres-Papaqui, V. Motta

Physics Faculty Publications

We have found that the brightest cluster galaxy (BCG) in A85, Holm 15A, displays the largest core known so far. Its cusp radius, r γ = 4.57 ± 0.06 kpc (426 ± 006), is more than 18 times larger than the mean for BCGs and 1 kpc larger than A2261-BCG, hitherto the largest-cored BCG. Holm 15A hosts the luminous amorphous radio source 0039-095B and has the optical signature of a LINER. Scaling laws indicate that this core could host a supermassive black hole (SMBH) of mass M • ~ (109-1011) M ☉. We suggest that cores this large represent a …

The Status Of Fishes In The Missouri River, Nebraska: Lake Sturgeon (Acipenser Fulvescens), Kirk D. Steffensen, Sam Stukel, Dane A. Shuman

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Lake Sturgeon (Acipenser fulvescens) occurrences in the Missouri River along Nebraska’s eastern border are historically sporadic and rare. Presently, the wild Lake Sturgeon population in this river reach may be extirpated. A Recovery Program initiated by the Missouri Department of Conservation (MDC) has stocked almost 150,000 hatchery-reared Lake Sturgeon into the lower Missouri River at several sites in Missouri. As a result, the number of Lake Sturgeon collected has increased. Since monitoring began in 2003, no Lake Sturgeon have been collected above Gavins Point Dam while 40 fish were collected downstream of Gavins Point Dam. The majority of …

Photophysical And Electronic Properties Of Low-Bandgap Semiconducting Polymers, Evan Lafalce

USF Tampa Graduate Theses and Dissertations

In this Ph.D. work, we investigate the optoelectronic properties of low-bandgap semiconducting polymers and project the potential for employing these materials in electronic and photonics devices, with a particular emphasis on use in organic solar cells. The field of organic solar cells is well developed and many of the fundamental aspects of device operation and material requirements have been established. However, there is still more work to be done in order for these devices to ultimately reach their full potential and achieve commercialization. Of immediate concern is the low power conversion efficiency demonstrated in these devices so far. In order …

The Figure Of Bitu-Man, Paul Royster

University of Nebraska-Lincoln Libraries: Faculty Publications

The ominously imposing figure in the above illustration is “the Syncrude bird deterrent device, locally known as ‘Bitu-man’.” He stands (or stood—the original image was from the late 1970s) in the tailings pond of the Syncrude Canada Ltd. oil sands mining operation along the Athabasca River near Fort McMurray in northeastern Alberta. That operation surface mines (i.e., strip mines) bitumen-impregnated sand, processes it with hot water and steam, and discharges the liquid effluent or “tailings” into a pond covering roughly 3000 hectares (11 square miles). (Google Map coordinates: 56.9°N, -111.3° W). Residue bitumen collects on the surface and poses a …

Digital Money: Bitcoin's Financial And Tax Future Despite Regulatory Uncertainty, Nicole Mirjanich

DePaul Law Review

Bitcoin, a virtual currency created in 2009, has resulted in the unlikely pairing of the underworld criminals with the Harvard educated Winklevoss brothers. The online currency can be obtained by “mining” through solving complex equations, and can be bought and sold on Bitcoin Exchanges. It is primarily utilized for investment in Bitcoin financial products as well as speculating on the value of the currency. It is also used as a method of payment for legal and illegal goods and services.

This comment addresses the regulatory issues Bitcoin faces, namely the regulation and taxation of financial products. After providing a fundamental …
