Evaluation Of A Prototype Desktop Virtual Reality Model Developed To Enhance Electrical Safety And Design In The Built Environment, Martin Barrett, Jonathan Blackledge

Articles

The use of Desktop Virtual Reality (VR) systems for enhancing electrical safety and engineering design is a novel prospect for both practicing and student electrical services engineers. This innovative approach, which can be readily accessed via the World Wide Web, constitutes a marked shift in conventional learning and design techniques to a more immersive, interactive and intuitive working and learning environment. This paper initially identifies the unique characteristics of desktop web based VR technologies and highlights the educational affordances offered by working in such an environment. Subsequently, using a prototype model titled ‘Virtual Electrical Services’, a case study is carried …

A Teaching Practice Review Of The Use Of Multiple-Choice Questions For Formative And Summative Assessment Of Student Work On Advanced Undergraduate And Postgraduate Modules In Engineering, Aidan O'Dwyer

Articles

This paper reflects on, reports on and evaluates the use of multiple-choice questions, in both formative and summative assessment modes, on control engineering modules taken by advanced undergraduate and postgraduate engineering students, over four academic years. The material covered by the modules is analytical in nature. The rationale for examining the assessment strategy was the poor performance by students in a closed book traditional terminal examination on one of the advanced undergraduate modules over some years. The change in assessment strategy has improved student learning, as measured by assessment data; student feedback on the assessment methods is broadly positive. The …

Non-Gaussian Anisotropic Diffusion Processing For Medical Imagining Using The Osirix Dicom Viewer, Jonathan Blackledge, Matthew Blackledge, Jane Courtney

Articles

Medical imaging is a fertile area for computer graphics, image processing and real time visualization. In this paper we present a method for reducing noise in CT (Computed Tomography) and MR (Magnetic Resonance) images that (in addition to other noise sources) is characteristic of the numerical procedures required to construct the images, namely, the (inverse) Radon Transform. In both cases, MR imaging in particular, an additional noise source is due to the process of diffusion thereby predicating use of the Anisotropic Diffusion method for noise suppression. This method is based on a diffusion model for noise generation where the Diffusivity …

Properties Of Non-Tilted Bent-Core Orthogonal Smectic Liquid Crystal, S. Sreenilayam, M. Nagaraj, Yuri Panarin, J. K. Vij, A. Lehmann, C. Tschierske

Articles

We present the properties of different achiral orthogonal polar smectic phases observed in a homologous series of bent-core molecular compounds. The macroscopically uniaxial SmAPR phase transforms to biaxial state by the application of higher electric fields and biaxial SmAPA phase undergoes biaxial-uniaxial-biaxial texture transformation with increasing electric fields,i.e.,initial antiferroelectric structure transforms into ferroelectric state under higher electric fields and it shows three different optically distinguishable states. The SmAPAR phase shows an entirely different response compared to other polar smectic phases under study. The dielectric measurements in the SmAPAR phase is the evidence of antiferroelectric behavior of uniaxial state. The polarizing …

Structure And Polymorphism Of Biaxial Bent-Core Smectic Liquid Crystal, S. Sreenilayam, M. Nagaraj, Yuri Panarin, J. K. Vij, A. Lehmann, C. Tschierske

Articles

The mesomorphic properties of a homologous series of achiral bent-core compounds are studied by polarizing optical microscopy, electro-optics and polarization measurements. Induction of a new orthogonal smectic phases with the increase of alkyl side chain length was observed. One of the compounds exhibits a unique phase transition between four non-tilted smectic phases (SmAPA–SmAPAR-SmAPR-SmA). The uniaxial but antiferroelectric nature of SmAPAR phase was confirmed by POM, current response, the 2nd harmonic electro-optic response and polarization measurements. The structure of SmAPAR phase was studied theoretically by Next-Nearest-Neighbor model and was identified as SmAPα.

The Libyan Model And Strategy: Why It Won't Work In Syria, Lance Kildron

Journal of Strategic Security

Operation Unified Protector (Libya, 2011) is the latest example of how a limited-means military intervention in a humanitarian crisis can stop the murder of innocent civilians. Proponents of intervention in the name of "responsibility to protect" (R2P) have stated that the air campaign strategy used in Libya could be the model for future U.S. military engagement overseas. This begs the question of when the United States should insert itself militarily into a humanitarian crisis. For instance, Syria is a potential candidate for military intervention. The following article takes the reasons for military intervention in Libya, as explained by President Obama …

In Their Own Words? Methodological Considerations In The Analysis Of Terrorist Autobiographies, Mary Beth Altier, John Horgan, Christian Thoroughgood

Journal of Strategic Security

Despite the growth of terrorism literature in the aftermath of the 9/11 attacks, there remain several methodological challenges to studying certain aspects of terrorism. This is perhaps most evident in attempts to uncover the attitudes, motivations, and intentions of individuals engaged in violent extremism and how they are sometimes expressed in problematic behavior. Such challenges invariably stem from the fact that terrorists and the organizations to which they belong represent clandestine populations engaged in illegal activity. Unsurprisingly, these qualities make it difficult for the researcher to identify and locate willing subjects of study—let alone a representative sample. In this research …

Exploiting Seams And Closing Gaps: Lessons From Mumbai And Beyond, Andrea Dew

Journal of Strategic Security

This article analyzes a single event—the 2008 Mumbai attacks—in order to consider the strategic and operational lessons for dealing with other armed groups. How and why was Lashkar-e-Tayyiba (LeT) able to carry out such a sophisticated attack in the heart of Mumbai? And what lessons does Mumbai hold for strategists seeking to counter other armed groups around the world? While tactical level lessons from Mumbai have been well documented, it is important to also consider what the Mumbai attacks tell us at the strategic and operational levels. Specifically, the Mumbai attacks provide valuable insight into how armed groups use the …

Overcoming Poverty Through Digital Inclusion, Marco Figueiredo, Paola Prado, Mark Cramer

Arts & Sciences Faculty Publications

A growing body of research is showing how digital inclusion can help communities overcome poverty and injustice. The main challenge lies in how best to achieve this goal. The authors argue that digital inclusion must occur in two distinct stages. The first stage is digital literacy, accomplished with the Symbiotic Computer (SC)-smartphones and tablets. The second stage will be professional capacity-building, accomplished with the more traditional Personal Computer (PC).

Diversity And Dynamics Of Bacterial Communities In Early Life Stages Of The Caribbean Coral Porites Astreoides, Koty H. Sharp, Dan Distel, Valerie J. Paul

Arts & Sciences Faculty Publications

In this study, we examine microbial communities of early developmental stages of the coral Porites astreoides by sequence analysis of cloned 16S rRNA genes, terminal restriction fragment length polymorphism (TRFLP), and fluorescence in situ hybridization (FISH) imaging. Bacteria are associated with the ectoderm layer in newly released planula larvae, in 4-day-old planulae, and on the newly forming mesenteries surrounding developing septa in juvenile polyps after settlement. Roseobacter clade-associated (RCA) bacteria and Marinobacter sp. are consistently detected in specimens of P. astreoides spanning three early developmental stages, two locations in the Caribbean and 3 years of collection. Multi-response permutation procedures analysis …

Opportunities For Public Aquariums To Increase The Sustainability Of The Aquatic Animal Trade, Michael F. Tlusty, Andrew L. Rhyne, Les Kaufman, Michael Hutchins, Gordon Mcgregor Reid, Chris Andrews, Paul Boyle, Jay Hemdal, Frazer Mcgilvray, Scott Dowd

Arts & Sciences Faculty Publications

The global aquatic pet trade encompasses a wide diversity of freshwater and marine organisms. While relying on a continual supply of healthy, vibrant aquatic animals, few sustainability initiatives exist within this sector. Public aquariums overlap this industry by acquiring many of the same species through the same sources. End users are also similar, as many aquarium visitors are home aquarists. Here we posit that this overlap with the pet trade gives aquariums significant opportunity to increase the sustainability of the trade in aquarium fishes and invertebrates. Improving the sustainability ethos and practices of the aquatic pet trade can carry a …

Shedding Light On The Larval Genus Eretmocaris: Morphological Larval Features Of Two Closely Related Trans-Isthmian Lysmata Species (Decapoda: Caridea: Hippolytidae) Described On The Basis Of Laboratory Cultured Material, Cátia Bartilotti, Ricardo Calado, Andrew L. Rhyne, Antonina Dos Santos

Arts & Sciences Faculty Publications

Complete larval series are known for only three of the 39 valid species worldwide in the genus Lysmata. The present work deals with the larval development of two closely related trans-isthmian species of Lysmata, L. galapagensis (eastern Pacific Ocean), and L. moorei (southwestern Atlantic Ocean), using laboratory cultured material. The morphological features of the first four zoeal stages of both species, the fifth to seventh stages of L. galapagensis, and the last stage of L. moorei are described and compared with the larval descriptions currently available for the genus. Larvae of both species hatch with a …

Antiamoebic Properties Of The Actinomycete Metabolites Echinomycin A And Tirandamycin A, Avelina Espinosa, Aaron M. Socha, Erica Ryke, David C. Rowley

Arts & Sciences Faculty Publications

Entamoeba histolytica infects 50 million people per year, causing 100,000 deaths worldwide. The primary treatment for amoebiasis is metronidazole. However, increased pathogen resistance combined with the drug’s toxic side effects encourages a search for alternative therapeutic agents. Secondary metabolites from marine bacteria are a promising resource for antiprotozoan drug discovery. In this study, extracts from a collection of marine-derived actinomycetes were screened for antiamoebic properties, and the activities of antibiotics echinomycin A and tirandamycin A are shown. Both antibiotics inhibited the in vitro growth of a E. histolytica laboratory strain (HM-1:IMSS) and a clinical isolate (Colombia, Col) …

Discrimination, Crypticity, And Incipient Taxa In Entamoeba, Avelina Espinosa, Guillermo Paz-Y-Miño-C

Arts & Sciences Faculty Publications

Persistent difficulties in resolving clear lineages in diverging populations of prokaryotes or unicellular eukaryotes (protistan polyphyletic groups) are challenging the classical species concept. Although multiple integrated approaches would render holistic taxonomies, most phylogenetic studies are still based on single-gene or morphological traits. Such methodologies conceal natural lineages, which are considered “cryptic.” The concept of species is considered artificial and inadequate to define natural populations. Social organisms display differential behaviors toward kin than to nonrelated individuals. In “social” microbes, kin discrimination has been used to help resolve crypticity. Aggregative behavior could be explored in a nonsocial protist to define phylogenetic varieties …

Effects Of Four Commercially Available Fxa Proteins On The Fluorogenic Anti-Fxa Assay When Monitoring Unfractionated Heparin, Vanessa Castro-Lopez, Brian Murray, Leanne F. Harris, James S. O'Donnell, Anthony J. Killard

Articles

Four commercially available Factor Xa (FXa) reagents were evaluated in a fluorogenic anti-FXa assay. The four reagents - of which three were of human origin and the fourth was bovine - were compared in terms of the resulting assay dynamic ranges, lag times, CV and R2 values, sum of squares as well as their sensitivity to unfractionated heparin (UFH) within the therapeutic range of 0-1.2 U mL-1. Based on a balance of performance characteristics, an optimum reagent was selected which had the best combination of all parameters. The best performing serine endopeptidase in the fluorogenic anti-FXa assay was found to …

Lower Court Constitutionalism: Circuit Court Discretion In A Complex Adaptive System, Doni Gewirtzman

American University Law Review

While federal circuit courts play an essential role in defining what the Constitution means, one would never know it from looking at most constitutional scholarship. The bulk of constitutional theory sees judge-made constitutional law through a distorted lens, one that focuses solely on the Supreme Court with virtually no attention paid to other parts of the judicial hierarchy. On the rare occasions where circuit courts appear on the radar screen, they are treated either as megaphones for communicating the Supreme Court’s directives or as tools for implementing the theorist’s own interpretive agenda. Both approaches would homogenize the way circuit courts …

The Second-Class Action: How Courts Thwart Wage Rights By Misapplying Class Action Rules, Scott A. Moss, Nantiya Ruan

American University Law Review

Courts apply to wage rights cases an aggressive scrutiny that not only disadvantages low-wage workers, but is fundamentally incorrect on the law. Rule 23 class actions automatically cover all potential members if the court grants plaintiffs’ class certification motion. But for certain employment rights cases—mainly wage claims but also age discrimination and gender equal pay claims—29 U.S.C. § 216(b) allows not class actions but “collective actions” covering just those opting in affirmatively. Yet courts in collective actions assume a gatekeeper role just as they do in Rule 23 class actions, disallowing many actions by requiring a certification motion proving strict …
