Passive Self-Interference Suppression For Single Channel Full-Duplex Operation, Adam Narbudowicz, Giuseppe Ruvio, Max Ammann

Articles

Full duplex radios have become a topic of increased interest in the wireless communications community. As part of this development, many efforts were directed to passively decrease the self-interference level at the antenna outputs. However, in many proposed solutions transmission and reception occur through different propagation channels. This paper demonstrates and quantifies the negative impact of channel differentiation on pivotal applications of full-duplex radio, such as cognitive radio. Antenna designs used for self-interference suppression in full-duplex radio architectures are analyzed. In order to ensure that transmission and reception occur within the same propagation channel, the use of the envelope correlation …

Guard Sets In Tor Using As Relationships, Mohsen Imani, Armon Barton, Matthew Wright

Articles

The mechanism for picking guards in Tor suffers from security problems like guard fingerprinting and from performance issues. To address these issues, Hayes and Danezis proposed the use of guard sets, in which the Tor system groups all guards into sets, and each client picks one of these sets and uses its guards. Unfortunately, guard sets frequently need nodes added or they are broken up due to fluctuations in network bandwidth. In this paper, we first show that these breakups create opportunities for malicious guards to join many guard sets by merely tuning the bandwidth they make available to Tor, …

Prosocial Religion And Games: Lost & Found, Owen Gottlieb, Ian Schreiber

Articles

In a time when religious legal systems are discussed without an understanding of history or context, it is more important than ever to help widen the understanding and discourse about the prosocial aspects of religious legal systems throughout history. The Lost & Found (www.lostandfoundthegame.com) game series, targeted for an audience of teens through twentysomethings in formal, learning environments, is designed to teach the prosocial aspects of medieval religious systems—specifically collaboration, cooperation, and the balancing of communal and individual/family needs. Set in Fustat (Old Cairo) in the 12th century, the first two games in the series address laws in Moses Maimonides’ …

Your Iphone Cannot Escape History, And Neither Can You: Self-Reflexive Design For A Mobile History Learning Game, Owen Gottlieb

Articles

This chapter focuses on the design approach used in the self-reflexive finale of the mobile augmented reality history game Jewish Time Jump: New York. In the finale, the iOS device itself and the player using it are implicated in the historical moment and theme of the game. The author-designer-researcher drew from self-reflexive traditions in theater, cinema, and nonmobile games to craft the reveal of the connection between the mobile device and the history that the learners were studying. Through centering on this particular design element, the author demonstrates how self-reflexivity can be deployed in a mobile learning experience to …

Health Sciences Students' Interest In And Opinions About Global Health Experiences, John B. Oliphant

Articles

While there is a significant body of literature regarding the interest in global health experiences (GHEs) for medical students and resident physicians, there is very little published in the scholarly literature regarding whether college/university students who are not in medical school, but are interested in pursuing a medical, health science, or allied health career in their future are also interested in global health.

An anonymous electronic survey was sent to students enrolled in the College of Health Sciences and Technology at Rochester Institute of Technology to assess how important these students felt it was for them to learn about global …

Towards Prioritizing Documentation Effort, Paul W. Mcburney, Siyuan Jiang, Marouane Kessentini, Nicholas A. Kraft, Ameer Armaly, Mohamed Wiem Mkaouer, Collin Mcmillan

Articles

Programmers need documentation to comprehend software, but they often lack the time to write it. Thus, programmers must prioritize their documentation effort to ensure that sections of code important to program comprehension are thoroughly explained. In this paper, we explore the possibility of automatically prioritizing documentation effort. We performed two user studies to evaluate the effectiveness of static source code attributes and textual analysis of source code towards prioritizing documentation effort. The first study used open-source API Libraries while the second study was conducted using closed-source industrial software from ABB. Our findings suggest that static source code attributes are poor …

Informing Quality In Emergency Care: Understanding Patient Experiences, Esmat Swallmeh, Vivienne Byers, Amr Arisha

Articles

Purpose: Assessing performance and quality in healthcare organisations is moving from focussing solely on clinical care measurement to considering the patient experience as critical. Much patient experience research is quantitative and survey based. The purpose of this paper is to report a qualitative study gathering in-depth data in an emergency department (ED).

Design/methodology/approach: The authors used empirical data from seven focus groups to understand patient experience as participants progressed through a major teaching hospital in an Ireland ED. A convenience sampling technique was used, and 42 participants were invited to share their perceptions and outline key factors affecting their journey. …

Dans La Serre: Framing The Greenhouse In Le Jour Se Lève (1939) And La Règle Du Jeu (1939), Barry Nevin

Articles

Beyond the year of their production, their notoriously foreboding references to contemporary national and international politics, and their shared status as canonised classics of French cinema, Marcel Carné’s Le Jour se lève (1939) and Jean Renoir’s La Règle du jeu (1939) both portray the romantic union of two parties within a greenhouse. This article aims to elaborate on these images in two central ways: first, it theorises glass in cinema with reference to the writings of André Bazin and Gilles Deleuze; second, it situates Carné and Renoir’s greenhouses within their respective dramatic, aesthetic and political contexts. In both cases, the …

Contesting Early Childhood Professional Identities: A Cross-National Discussion, Sonja Arndt, Mathias Urban, Colette Murray, Kylie Smith, Beth Swadener, Tomas Ellegaard

Articles

In this collective article, the authors explore constructions of early childhood practitioners and how they disconnect and reconnect in a global neo-liberal education policy context. The contributions to the conversation provide windows into shifting professional identities across five national contexts: New Zealand, the USA, Ireland, Australia and Denmark. The authors ask who benefits from the notion of distinct professional identities, linked to early childhood education as locally and culturally embedded practice. They conceptualize teachers’ shifting subjectivities, drawing on Kristeva’s philosophical conception of identity as constantly in construction, open and evolving. Arguments for the urgency to counter the global uniformity machine, …

Becoming A Decolonial Feminist Ethnographer: Addressing The Complexities Of Positionality And Representation, Jennifer Manning

Articles

Abstract Organisation and management scholars are often preoccupied with developing, refining and advancing knowledge, and in so doing, the empirical process through which knowledge is advanced can be ignored together with the impact this process can have on participants and scholars. This article draws attention to how management scholars might negotiate the complexities of positionality and representation through an illustrative case: my experience of becoming a decolonial feminist ethnographer. Drawing upon my doctoral research, I share the experience of my ethnographic journey to become a decolonial feminist ethnographer. Developing a decolonial feminist approach to ethnography enabled me to identify positionality …

A Scientometric Analysis Of Knowledge Management Research And Practice Literature: 2003 – 2015, Ahmed Ramy, Jenni Floody, Mohamed Af Ragab, Amr Arisha

Articles

The purpose of this paper is to explore the current research trends in Knowledge Management (KM) through a scientometric analysis of all literature published in KMRP between 2003 and 2015 (506 articles). The review framework explores three sets of review questions addressing Research Productivity, Research Themes and Methods, and Citation Analysis. The study elucidates wide global interest in KM and an increasing trend towards multi-author collaboration. Although more than 55 different industries have featured in the journal, certain knowledge-intensive sectors remain underrepresented. Country productivity shows few nations taking the lead with an interesting correlation between research activity and economic prosperity. …

Self-Healing Asphalt Review: From Idea To Practice, S. Xu, Alvaro García, Junfeng Su, Quantao Liu, Amir Tabakovic, Erik Schlangen

Articles

With the advantages of cost efficiency, noise reduction, and comfort driving experience, asphalt is widely used as a binding material in pavement engineering. However, after years of serving, asphalt concrete gets damaged under cyclic vehicle loading. Meanwhile, due to environmental effects including ageing and moisture damage, asphalt binder becomes brittle with time. As a result, microcracks initiate and grow into larger scales, which accelerates the damaging process and finally leads to distresses like raveling, potholes, cracking, and so on. In 1967, Bazin and Saunier[1] witnessed and reported a temperature related healing phenomenon in asphalt mix after loadings. After that, the …

Maritime Spatial Planning Supported By Infrastructure For Spatial Information In Europe (Inspire), Andrej Abramic, Emanuele Bigagli, Vittorio Barale, Alberto Lorenzo-Alonso, Conor Norton

Articles

The implementation of Directive 2007/2/EC - INSPIRE can improve and actually strengthen the informationmanagement and data infrastructures needed for setting up Maritime Spatial Planning (MSP) processes. Evidencefor this comes from three parallel analyses: links between the MSP Framework Directive and INSPIRE compo-nents and implementation; the availability of marine and maritime data through the INSPIRE Geo-Portal; andthe adequacy of using an INSPIRE data model for mapping maritime spatial plans. Thefirst item identifiesINSPIRE as a relevant instrument not only for data collection, but additionally for increasing transparency of theMSP processes, using already operational national and European data infrastructure. The marine/maritime dataavailability analysis …

Thermo-Optic Tuning Of A Packaged Whispering Gallery Mode Resonator Filled With Nematic Liquid Crystal, Vishnu Kavungal, Gerald Farrell, Qiang Wu, Arun Mallik, Yuliya Semenova

Articles

Thermo-optic tuning of whispering gallery modes (WGMs) in a nematic liquid crystal-filled thin-walled capillary tube resonator is reported. WGMs were excited by the evanescent field from a tapered optical fiber. Tapered optical fiber fabrication and reduction of wall thickness of the capillary tube was carried out by a ceramic micro-heater brushing technique. A simple and robust packaging technique is demonstrated to ensure stable and repeatable operation of the device. Tunability of WGMs with temperature was demonstrated with a sensitivity of 267.5 ± 2.5 pm/°C. The demonstrated thermo-optic method for WGMs tuning is potentially useful for many tunable photonic devices and …

Highly Sensitive Twist Sensor Based On Partially Silver Coated Hollow Core Fiber Structure, Dejun Liu, Rahul Kumar, Fangfang Wei, Wei Han, Arun Mallik, Jinhui Yuan, Chongxiu Yu, Feng Li, Zhengyong Liu, Hwa-Yaw Tam, Gerald Farrell, Yuliya Semenova, Qiang Wu

Articles

Interferometer based on multiple beam interferences inside a hollow core fiber (HCF) structure (also known as an antiresonant reflecting optical waveguide) has been attracting interest of many researchers due to its periodic transmission spectrum containing high quality factor spectral dips. Functionalized HCF structures have been demonstrated for a wide range of applications in humidity, magnetic field, and biosensing. Here, we report a new application of the HCF-based structure with a partial silver coating layer for sensing of twist. It is configured by a fusion splicing a section of 4.5-mm long HCF between two standard single mode fibers (SMFs), followed by …

A Pseudo-Microsimulation Approach For Modelling Congested Traffic Loading On Long-Span Bridges, Colm Carey, Colin Caprani, Bernard Enright

Articles

This paper investigates congested traffic loading on long-span bridges through the use of traffic microsimulation. Six months of Weigh-In-Motion free-flow traffic data (including cars) are used as input for the microsimulation of congested traffic. Key parameters that affect traffic loading are identified in the output of the microsimulation, and these parameters form the basis for a more computationally efficient ‘pseudo-microsimulation of congested traffic’ (PMCT) model. This PMCT model is shown to replicate the traffic loading from full microsimulation accurately and allows long-run simulations, equivalent to 1000 years of congested traffic, to be performed with an acceptably short duration. This reduces …

Empowering Students To Perform An Enhanced Role In The Assessment Process: Possibilities And Challenges, Paul Dervan

Articles

Assessment is key to student learning. This paper examines the case for increased participation by higher education students in the assessment process to deepen learning and improve learner motivation. While increased student participation may not solve all problems relating to assessment, a review of the literature dealing with enhancing the role of students in the assessment process, and original research conducted amongst academics and students at the author's institution, suggests improvements can be made leading to increased student satisfaction, motivation and competency. This paper therefore argues for change in the approach to assessment by empowering students to become partners in …

The Kitchen Light Of Ntid, Miriam Lerner

Articles

It is often noted that great events are a concurrence of great people, great ideas, and the right time and place for the perfect fusion of energy to explode into a super nova of enlightenment. It can be difficult to find specific times and locations when great changes and shifts in attitude occur, as they usually follow a more geologic model of slow and almost imperceptible change over time. However, when considering ASL poetry and lit erature, the importance of NTID and specifically the Panara Theatre housed in LBJ Hall cannot be overstated. The right people, and—of paramount importance—the right …

Arbiters Of Decency: A Study Of Legislators' Eighth Amendment Role, Aliza Plener Cover

Articles

Within Eighth Amendment doctrine, legislators are arbiters of contemporary values. The United States Supreme Court looks closely to state and federal death penalty legislation to determine whether a given punishment is out of keeping with “evolving standards of decency.” Those who draft, debate, and vote on death penalty laws thus participate in both ordinary and higher lawmaking. This Article investigates this dual role.

We coded and aggregated information about every floor statement made in the legislative debates preceding the recent passage of bills abolishing the death penalty in Connecticut, Illinois, and Nebraska. We categorized all statements according to their position …

Dismantling Monuments, Richard Henry Seamon

Articles

The Antiquities Act of 1906 authorizes the President to "declare" certain objects "to be national monuments," and to "reserve parcels of land" to protect those national monuments. The Act does not expressly authorize the President to reduce or rescind a monument established by a prior President under the Act, and recent actions by President Donald Trump raise the question whether the Act impliedly authorizes such reductions or rescissions. The majority of legal scholars who have studied this question have said no, the Act does not grant such implied authority. This Article takes the contrary position. The President's authority under the …

Incorporating Social System Dynamics In The Columbia River Basin: Food-Energy-Water Resilience And Sustainability Modeling In The Yakima River Basin, Barbara Cosens

Articles

In the face of climate change, achieving resilience of desirable aspects of food-energy-water (FEW) systems already strained by competing multi-scalar social objectives requires interdisciplinary approaches. This study is part of a larger effort exploring “Innovations in the Food-Energy-Water Nexus (INFEWS)” in the Columbia River Basin (CRB) through coordinated modeling and simulated management scenarios. Here, we focus on a case study and conceptual mapping of the Yakima River Basin (YRB), a sub-basin of the CRB. Previous research on FEW system management and resilience includes some attention to social dynamics (e.g., economic and governance systems); however, more attention to social drivers and …

“After Hollywood And Its Ever-Blue Skies, How Beautiful Paris Looks!”: Jacques Feyder Between France And America, 1928-1934, Barry Nevin

Articles

Although generally relegated by present-day historians to the footnotes of film history, Belgian director Jacques Feyder (1885–1948) strove to elevate the artistic standards of French film production throughout the 1920s and 1930s. His departure for Metro-Goldwyn-Mayer studios on the cusp of the transition to sound in France was viewed as a crisis, and his return was hailed as an event. Drawing on contemporary periodicals, this article answers two fundamental questions: Why did France's leading am bassador leave his adoptive homeland? And what factors motivated his return to France despite the country's notoriously anarchic mode of production? Core concerns include Feyder's …

Severe Brain Injury, Disability, And The Law: Achieving Justice For A Marginalized Population, Megan S. Wright, Nina Varsava, Joel Ramirez, Kyle Edwards, Nathan Gueveremont, Tamar Ezer, Joseph J. Fins

Articles

Thousands of persons with severe brain injury who are minimally conscious or "locked in" are wrongly treated as if they are unconscious. Such individuals are unable to advocate for themselves and are typically segregated from society in hospitals or nursing homes. As a result, they constitute a class of persons who often lack access to adequate medical care, rehabilitation, and assistive devices that could aid them in communication and recovery. While this problem is often approached from a medical or scientific point of view, here we frame it as a legal issue amenable to legal remedies. This Article comprehensively explores …

Fearless Speech, Mary Anne Franks

Articles

The American conception of free speech is primarily defined as the freedom to say whatever one wants, with little regard for the quality, context, or impact of the speech. Thus, American free speech doctrine is often characterized as neutral with regard to the speaker and the content of speech; in practice, however, it consistently privileges powerful over vulnerable speakers and harmful over critical speech.

From Philadelphia to Skokie to Charlottesville, the First Amendment has been interpreted to protect speech by white men that silences and endangers women and minorities. As free speech doctrine and practice become increasingly concerned with private …

The New Bond Workouts, William Wilson Bratton, Adam J. Levitin

Articles

Bond workouts are a famously dysfunctional method of debt restructuring. The process is so ridden with opportunistic and coercive behavior by both bondholders and bond issuers as to make success intrinsically unlikely. Yet since 2008 bond workouts have quietly started to work. A segment of the restructuring market has shifted from bankruptcy court to out-of-court workouts by way of exchange offers made only to large institutional investors. The new workouts feature a battery of strong-arm tactics by bond issuers, and aggrieved bondholders have complained in court. There resulted a new, broad reading of the primary law governing workouts, section 3 …
