Who Really Said What? Mobile Historical Situated Documentary As Liminal Learning Space, Owen Gottlieb

Articles

This article explores the complexities and affordances of historical representation that arose in the process of designing a mobile augmented reality video game for teaching history. The process suggests opportunities to push the historical documentary form in new ways. Specifically, the article addresses the shifting liminal space between historical fiction narrative, and historical interactive documentary narrative. What happens when primary sources, available for examination are placed inside of a historically inspired narrative, one that hews closely to the events, but creates drama through dialogues between player and historical figure? In this relatively new field of interactive historical situated documentary, how …

Mode-Sum Prescription For The Vacuum Polarization In Odd Dimensions, Peter Taylor, Cormac Breen

Articles

We present a new mode-sum regularization prescription for computing the vacuum polarization of a scalar field in static spherically-symmetric black hole spacetimes in odd dimensions. This is the first general and systematic approach to regularized vacuum polarization in higher dimensions. Remarkably, the regularization parameters can be computed in closed form in arbitrary dimensions and for arbitrary metric function $f(r)$. In fact, we show that in spite of the increasing severity and number of the divergences to be regularized, the method presented is mostly agnostic to the number of dimensions. Finally, as an explicit example of our method, we show plots …

Auditory Fatigue Model Applications To Predict Noise Induced Hearing Loss In Human And Chinchilla, Pengfei Sun, Daniel Fox, Kathleen Campbell, Jun Qin

Articles

Noise induced hearing loss (NIHL) remains a severe health problem worldwide. Current noise metrics and models have assessment limitations on gradually developing NIHL (GDNIHL). In this study, we apply a complex velocity level (CVL) auditory fatigue model to quantitatively assess the impact of basilar membrane (BM) movement on GDNIHL. The transfer functions of chinchilla and human auditory systems, including the triple-path nonlinear (TRNL) filters to simulate the inner ear responses, are applied to obtain BM velocity distribution. Chinchilla and human experimental hearing loss data are used to validate the proposed CVL model’s effectiveness. The results reveal that the developed CVL …

"The Most Patient Of Animals, Next To The Ass:" Jan Smuts, Howard University, And African American Leandership, 1930, Robert Edgar, Myra Ann Houser

Articles

Former South African Prime Minister Jan Smuts’ 1930 European and North American tour included a series of interactions with diasporic African and African American activists and intelligentsia. Among Smuts’s many remarks stands a particular speech he delivered in New York City, when he called Africans “the most patient of all animals, next to the ass.” Naturally, this and other comments touched off a firestorm of controversy surrounding Smuts, his visit, and segregationist South Africa’s laws. Utilizing news coverage, correspondence, and recollections of the trip, this article uses his visit as a lens into both African American relations with Africa and …

An Evaluation Of The Safety Of The Cycling In Dublin City For Dit Students, Niamh O' Reilly

Articles

Cycling as a mode of transport offers many benefits including a cheap, cost effective, healthy, fast, mainly congestion free and environmentally friendly means of getting to and from places of employment and education. Given the central location of Technological University Dublin campus buildings this would seem an ideal option for its third level students, but on the contrary, a DIT online travel survey conducted in March 2014 found that only 7% of students chose cycling as their primary mode of transport. Concerns about cyclist safety were a major factor cited by students who chose alternative modes of transport. Based on …

Be An Advocate For Others, Unless You Are A Man: Backlash Against Gender-Atypical Male Job Candidates, Mary Kinahan, Janine Bosak

Articles

Previous research shows that gender vanguards (individuals who demonstrate gender-atypical skills and behavior) suffer backlash in the form of social and economic penalties (Rudman & Phelan, 2008). This study examined backlash against female and male job applicants who were either gender-atypical or typical. Professionals (N = 149) evaluated female or male managerial applicants for internal promotion described in their performance review as showing either self-advocacy or advocacy on behalf of their team. Atypical, other-advocating men were judged to be low on agency and competence and penalized with job dismissal. Serial mediation analysis demonstrated that, compared with other-advocating women, other-advocating …

A Small Step Forwards On The Erd˝Os-S´Os Problem Concerning The Ramsey Numbers R(3, K), Rujie Zhu, Xiaodong Xu, Stanislaw Radziszowski

Articles

Let ∆s = R(K3, Ks) − R(K3, Ks−1), where R(G, H) is the Ramsey number of graphs G and H defined as the smallest n such that any edge coloring of Kn with two colors contains G in the first color or H in the second color. In 1980, Erd˝os and S´os posed some questions about the growth of ∆s. The best known concrete bounds on ∆s are 3 ≤ ∆s ≤ s, and they have not been improved since the stating of the problem. In this paper we present some constructions, which imply in particular that R(K3, Ks) ≥ …

An Examination Of The Neural Unreliability Thesis Of Autism, John Butler, Sophie Molholm, Gizely Andrade, John J. Foxe

Articles

An emerging neuropathological theory of Autism, referred to here as “the neural unreliability thesis,” proposes greater variability in moment-to-moment cortical representation of environmental events, such that the system shows general instability in its impulse response function. Leading evidence for this thesis derives from functional neuroimaging, a methodology ill-suited for detailed assessment of sensory transmission dynamics occurring at the millisecond scale. Electrophysiological assessments of this thesis, however, are sparse and unconvincing. We conducted detailed examination of visual and somatosensory evoked activity using high-density electrical mapping in individuals with autism (N = 20) and precisely matched neurotypical controls (N = 20), recording …

Teaching Android Security Through Examples: A Publicly Available Database Of Vulnerable Apps, Daniel E. Krutz, Samuel A. Malachowsky

Articles

Security is hard, and teaching security can be even harder. Here we describe a public educational activity to assist in the instruction of both students and developers in creating secure Android apps. Our set of activities includes example vulnerable applications, information about each vulnerability, steps on how to repair the vulnerabilities, and information about how to confirm that the vulnerability has been properly repaired. Our primary goal is to make these activities available to other instructors for use in their classrooms ranging from the K-12 to university settings. A secondary goal of this project is to foster interest in security …

Investigating The Impact Of Green Exercise On Population Health And Well-Being In A Small Community In Ireland:A Novel Approach Using A Natural Laboratory Ecosystem., Nollaig O'Sullivan, Aoife Donnelly, Tadhg Macintyre, Giles Warrington

Articles

Green exercise is defined as undertaking physical activity whilst being directly exposed to nature (Pretty et al., 2005; 2007). Pretty et al. (2003) were among the first wave of researchers to investigate the synergistic benefits of incorporating physical activity and exposure to the natural environment to produce positive psychological affect. Over the past decade, investigations into the possible additive effects on well-being of green exercise and how it can be used as an influential tool to help combat the rising rate of both physical inactivity and non –communicable disease has gained prominence in scientific literature. However, there is still a …

Organizational Responses To Institutional Pressures: Reconfiguration Of Spaces In Nanosciences And Nanotechnologies, Nicolas Battard, Paul Donnelly, Vincent Mangematin

Articles

The literature on organizational responses to institutional pressures describes responses ranging from compliance to resistance via different modes of decoupling. However, although these studies provide a greater understanding of the phenomenon, they tend to be disparate and to consider the different elements separately. Through a comparative case study of six research teams in the area of nanosciences and nanotechnologies, we offer three contributions. Our first is to the decoupling literature by way of a complementary and cohesive framework, which shows that organizations vary in their responses by reconfiguring their physical (policy and materiality), mental (meaning) and social (identity) spaces, and …

Modelling Random Antibody Adsorption And Immunoassay Activity, Dana Mackey, Eilis Kelly, Robert Nooney

Articles

One of the primary considerations in immunoassay design is optimizing the concentration of capture antibody in order to achieve maximal antigen binding and, subsequently, improved sensitivity and limit of detection. Many immunoassay technologies involve immobilization of the antibody to solid surfaces. Antibodies are large molecules in which the position and accessibility of the antigen-binding site depend on their orientation and packing density. In this paper we propose a simple mathematical model, based on the theory known as random sequential adsorption (RSA), in order to calculate how the concentration of correctly oriented antibodies (active site exposed for subsequent reactions) evolves during …

Dietary Nitrate Acutely And Markedly Increased Exhaled Nitric Oxide In A Cystic Fibrosis Case, Conor Kerley, Emma Kilbride, Peter Greally, Basil Elnazir

Articles

Airway nitric oxide (NO) is a ubiquitous signaling molecule with bronchoprotective, antiinflammatory and anti-infective roles. Cystic fibrosis (CF) is a chronic lung condition associated with deceased exhaled NO. Strategies to increase exhaled NO in CF have yielded inconsistent results. A potential new method of increasing systemic NO involves ingestion of dietary, inorganic nitrate which is reduced to nitrite and NO. We present the case of a 12 year-old, athletic male with CF who demonstrated acute but marked increases in exhaled NO following dietary nitrate consumption compared to placebo.

Bim Innovation Capability Programme: An Irish Bim Study, Barry Mcauley, Alan Hore, Roger West

Articles

In 2011 the Royal Institute of Architects Ireland (RIAI) conducted a survey which found that BIM adoption within Ireland was quite low at 16%. Over the last five years these figures have risen significantly, with the 2016 Irish Digital Transition Survey reporting that 76% of respondents possess confidence in their organisation’s BIM skills and knowledge. This represents a significant shift of BIM adoption in Ireland over the last five years.

The BIM Innovation Capability Programme (BICP) Irish BIM study, builds on the findings from the BICP Global BIM Study by providing an in depth review of BIM in Ireland with …

An Investigation Into Spent Coffee Waste As A Renewable Source Of Bioactive Compounds And Industrially Important Sugars, Damhan Scully, Amit Jaiswal, Nissreen Abu-Ghannam

Articles

Conventional coffee brewing techniques generate vast quantities of spent espresso grounds (SEGs) rich in lignocellulose and valuable bioactives. These bioactive compounds can be exploited as a nutraceutical or used in a range of food products, while breakdown of lignocellulose generates metabolizable sugars that can be used for the production of various high-value products such as biofuels, amino acids and enzymes. Response surface methodology (RSM) was used to optimize the enzymatic saccharification of lignocellulose in SEGs following a hydrothermal pretreatment. A maximum reducing sugar yield was obtained at the following optimized hydrolysis conditions: 4.97 g of pretreated SEGs, 120 h reaction …

Microbial Enzyme Production Using Lignocellulosic Food Industry Wastes As Feedstock: A Review, Amit Jaiswal, Rajeev Ravindran

Articles

Enzymes are of great importance in the industry due to their substrate and product specificity, moderate reaction conditions, minimal by-product formation and high yield. They are important ingredients in several products and production processes. Up to 30% of the total production cost of enzymes is attributed to the raw materials costs. The food industry expels copious amounts of processing waste annually, which is mostlylignocellulosicin nature. Upon proper treatment,lignocellulosecan replace conventional carbon sources in media preparations for industrial microbial processes, such as enzyme production. However, wild strains of microorganisms that produce industrially important enzymes show low yield and cannot thrive on …

Power-Weighted Divergences For Relative Attenuation And Delay Estimation, Ruairí De Fréin, Scott T. Rickard Prof

Articles

Power-weighted estimators have recently been proposed for relative attenuation and delay estimation in blind source separation. Their provenance lies in the observation that speech is approximately windowed-disjoint orthogonal (WDO) in the time-frequency (TF) domain; it has been reported that using WDO, derived from TF representations of speech, improves mixing parameter estimation. We show that power-weighted relative attenuation and delay estimators can be derived from a particular case of a weighted Bregman divergence. We then propose a wider class of estimators, which we tune to give better parameter estimates for speech.

Evaluation Of Ultrasound Assisted Potassium Permanganate Pre-Treatment Of Spent Coffee Waste, Rajeev Ravindran, Swarna Jaiswal, Nissreen Abu-Ghannam, Amit Jaiswal

Articles

In the present study, novel pre-treatment for spent coffee waste (SCW) has been proposed which utilises the superior oxidising capacity of alkaline KMnO₄ assisted by ultra-sonication. The pre-treatment was conducted for different exposure times (10, 20, 30 and 40 min) using different concentrations of KMnO₄ (1,2, 3, 4, 5% w/v) at room temperature with solid/liquid ratio of 1:10. Pretreating SCW with 4% KMnO₄ and exposing it to ultrasound for 20 min resulted in 98% cellulose recovery and a maximum lignin removal of 46%. 1.7fold increase in reducing sugar yield was obtained after enzymatic hydrolysis of KMnO_{4 …}

Fermentation-Assisted Extraction Of Isothiocyanates From Brassica Vegetable Using Box-Behnken Experimental Design, Amit Jaiswal, Nissreen Abu-Ghannam

Articles

Recent studies showed that Brassica vegetables are rich in numerous health-promoting compounds such as carotenoids, polyphenols, flavonoids, and glucosinolates (GLS), as well as isothiocyanates (ITCs) and are involved in health promotion upon consumption. ITCs are breakdown products of GLS, and typically used in the food industry as a food preservative and colouring agent. They are also used in the pharmaceutical industry due to their several pharmacological properties such as antibacterial, antifungal, antiprotozoal, anti-inflammatory, and chemoprotective effects, etc. Due to their widespread application in food and pharmaceuticals, the present study was designed to extract ITCs from York cabbage. In order to …

Gear Tooth Mesh Stiffness: A Comparison Of Calculation Approaches, Christopher G. Cooley, Chunguang Liu, Xiang Dai, Robert G. Parker

Articles

This work compares spur gear tooth mesh stiffness calculations using two approaches. The first is a common approach from the literature that calculates the mesh stiffness by dividing the mesh force by the mesh deflection, which we call the average slope method. The second approach calculates the local slope of the force-deflection curve about a nominal deflection. The two approaches result in meaningfully different mesh stiffness predictions that persist for wide ranges of applied torque and for gear teeth with tooth surface modifications. It is shown that each calculation approach has its own distinct use, broadly divided as average slope …

Ultra-Filtration Of Human Serum For Improved Quantitative Analysis Of Low Molecular Weight Biomarkers Using Atr-Ir Spectroscopy, Franck Bonnier, Helene Blasco, Clement Wasselet, Guillaume Brachet, Renaud Respaud, Luis Felipe Cs. Carvalho, Dominque Bertrand, Mathew J. Baker, Hugh Byrne, Igor Chourpa

Articles

Infrared spectroscopy is a reliable, rapid and cost effective characterisation technique, delivering a molecular finger print of the sample. It is expected that its sensitivity would enable detection of small chemical variations in biological samples associated with disease. ATR-IR is particularly suitable for liquid sample analysis and, although air drying is commonly performed before data collection, just a drop of human serum is enough for screening and early diagnosis. However, the dynamic range of constituent biochemical concentrations in the serum composition remains a limiting factor to the reliability of the technique. Using glucose as a model spike in human serum, …

Evaluating The Afdb “High 5’S”: Bifocal Lenses Assessment Via Citizen Participation, Oluwasegun O. Seriki

Articles

The thought of evaluating the AfDB high 5’s is tempting. It is, in fact, a herculean task and cannot just be achieved using a blanket approach or be dismissed with the common approach “…difficult is done at once; the impossible takes a little longer”. In reality, evaluating these high priority areas will involve much rigour and will involve finding that one area that is lacking but can improve on with a single change of lenses, consequently improving circumstances drastically. The high 5’s garner much attention in headlines, much is said about it, talks, seminars, and — who knows — maybe …
