A Novel Parabolic Model Of Instructional Efficiency Grounded On Ideal Mental Workload And Performance, Luca Longo, Murali Rajendran

Articles

Instructional efficiency within education is a measurable concept and models have been proposed to assess it. The main assumption behind these models is that efficiency is the capacity to achieve established goals at the minimal expense of resources. This article challenges this assumption by contributing to the body of Knowledge with a novel model that is grounded on ideal mental workload and performance, namely the parabolic model of instructional efficiency. A comparative empirical investigation has been constructed to demonstrate the potential of this model for instructional design evaluation. Evidence demonstrated that this model achieved a good concurrent validity with the …

A Survey Of Machine Learning Techniques For Video Quality Prediction From Quality Of Delivery Metrics, Obinna Izima, Ruairí De Fréin, Ali Malik

Articles

A growing number of video streaming networks are incorporating machine learning (ML) applications. The growth of video streaming services places enormous pressure on network and video content providers who need to proactively maintain high levels of video quality. ML has been applied to predict the quality of video streams. Quality of delivery (QoD) measurements, which capture the end-to-end performances of network services, have been leveraged in video quality prediction. The drive for end-to-end encryption, for privacy and digital rights management, has brought about a lack of visibility for operators who desire insights from video quality metrics. In response, numerous solutions …

Beyond The Public Square: Imagining Digital Democracy, Mary Anne Franks

Articles

To create online spaces that do not merely replicate existing hierarchies and reinforce unequal distributions of social, economic, cultural, and political power, we must move beyond the simplistic clich6 of the unregulated public square and commit to the hard work of designing for democracy.

When we say 'public square,' ... we need to ask- who or what is this public? Who owns this space, what makes it public? . . . This is the essence of democracy: the ability to question power, and the power to do so. - Tom Wilkinson

A Strategy Model For Workplace Mediation Success, Brian M. Barry Dr

Articles

The article proposes a three-step model to help workplace mediators decide on the optimum strategy for mediating workplace disputes. The model uses a grid – the Workplace Mediation Strategy Grid – which is based on a modified version of a grid Professor Leonard Riskin developed for categorising mediation orientations (Riskin 1994; Riskin 1996). The model asks the mediator to first consider the nature of the workplace dispute based on three facets of the dispute. This guides the mediator to plot a position on the Grid which represents two fundamental aspects of strategy for mediating that dispute: (1) how broadly the …

Towards A Framework For Comparing Functionalities Of Multimorbidity Clinical Decision Support: A Literature-Based Feature Set And Benchmark Cases., Dympna O'Sullivan, William Van Woensel, Szymon Wilk, Samson Tu, Wojtek Michalowski, Samina Abidi, Marc Carrier, Ruth Edry, Irit Hochberg, Stephen Kingwell, Alexandra Kogan, Martin Michalowski, Hugh O'Sullivan, Mor Peleg

Articles

Multimorbidity, the coexistence of two or more health conditions, has become more prevalent as mortality rates in many countries have declined and their populations have aged. Multimorbidity presents significant difficulties for Clinical Decision Support Systems (CDSS), particularly in cases where recommendations from relevant clinical guidelines offer conflicting advice. A number of research groups are developing computer-interpretable guideline (CIG) modeling formalisms that integrate recommendations from multiple Clinical Practice Guidelines (CPGs) for knowledge-based multimorbidity decision support. In this paper we describe work towards the development of a framework for comparing the different approaches to multimorbidity CIG-based clinical decision support (MGCDS). We present …

Love Hertz: Corporate Groups And Insolvency Forum Selection, John A. E. Pottow

Articles

The Hertz bankruptcy got a lot of attention, including for its bizarre equity trading. A less heralded but more significant legal aspect of that insolvency, however, was its complex interaction of cross-border insolvency proceedings.

This article discusses the “centripetal” and “centrifugal” forces in the Hertz case that counselled a U.S.-based centralized solution for an international enterprise comprising over 10,000 branches centripetally but also accommodated centrifugal European resistance to subject directors to the consequences of filing their entities in a foreign jurisdiction. This not uncommon constellation of incentives required not a COMI shift but what this article terms a jurisdiction shift …

Editing And Interleaving, Patrick Barry

Articles

This essay suggests that a powerful learning strategy called "interleaving"--which involves strategically switching between cognitive tasks--is being underused. It can do more than make study sessions more productive; it can also make editing sessions more productive.

Handouts Don’T Exist. Hustle Or You Don’T Eat., Conor Mcgarrigle Dr.

Articles

It is well established that AI has a bias problem; however, black-boxed machine learning systems render it difficult to even understand and visualize the nature and extent of the problem, let alone find solutions. This paper discusses an artistic research approach toward highlighting AI bias and explores the aesthetic potential of machine learning through a case study of an AI artwork called #RiseandGrind.The artist trained a recurrent neural network on a dataset extracted from Twitter hashtags (#Riseandgrind and #Hustle),which were selected to represent a specific filter bubble (embodied neoliberal precarity) in order to produce a biased AI that generates tweets …

Towards An Integrated Case Method In Management Education - Developing An Ecosystem-Based Research And Learning Journey For Flipped Classrooms, Jan-Philipp Buechler Prof Dr, Gregor Brüggelambert Prof Dr, Jan-Phillip Büchler Prfo Dr, Helen De.Haan-Cao Dr, Asta Savaneviciene Prof

Articles

In the field of management science and business administration, the case method is gaining ground in research as well as in teaching. Case studies support on the one hand exploratory re-search and on the other hand problem-based teaching. However, we find that case research and case teaching remain unchained in management study programs and propose to close this gap. We identify an untapped potential of boosting the case method by integrating case-based re-search and teaching into a discovery and learning journey of applied science. We suggest em-bedding the ‘Integrated Case Method’ (ICM) in the ecosystem of universities to the end …

Increasing Gender Balance Across Academic Staffing In Computer Science - Case Study, Susan Mckeever, Deirdre Lillis

Articles

As at 2019, Technological University Dublin* Computer Science is the top university in Ireland in terms of gender balance of female academic staff in computer science schools. In an academic team of approximately 55 full-time equivalents, 36% of our academic staff are female, 50% of our senior academic leadership team (2 of 4) are female and 75% of our School Executive are female (3 of 4), including a female Head of School. This is as a result of our seven year SUCCESS programme which had a four strand approach: Source, Career, Environment and Support. The Source strand explicitly encouraged females …

The Breakdown Of The Public-Private Divide In Securities Law: Causes, Consequences, And Reforms, George S. Georgiev

Articles

As a regulatory scheme, U.S. securities law has traditionally been designed around a set of lines-the 'public-private divide"-which separate public companies, public capital, and public markets, from private companies, private capital, and private markets. Until the early 2000s, the lines were successful in establishing two largely coherent legal realms-a highly regulated public realm and a lightly regulated private realm. A series of bold and often-inconsistent reforms between 2002 and 2020, however, have transformed this longstanding regime into a low-friction system wherein public capital flows to both public and private companies, private capital is ever more abundant, and firms can effectively …

Why Are You Here? Modeling Illicit Massage Business Location Characteristics With Machine Learning, Anna White, Seth Guikema, Bridgette Carr

Articles

Illicit massage businesses are a venue for sex and labor trafficking in the United States. Though many of their locations are made publicly available through online advertising, little is known about why they choose to locate where they do. In this work, we use inferential modeling to better understand the spatial distribution of illicit massage businesses within the U.S. Based on addresses web-scraped weekly from online advertisements over 6 months, we modeled illicit massage business prevalence at the census tract and county levels. We used publicly available data to characterize census tracts and counties, finding that the state in which …

Articles

Background

E-cigarette ever-use and current-use among teenagers has increased worldwide, including in Ireland.

Methods

We use data from two Irish waves (2015, 2019) of the European School Survey Project on Alcohol and other Drugs (ESPAD) to investigate gender and teenage e-cigarette use (n = 3421 16-year-olds). Using chi-square analyses, we report changes in e-cigarette ever-use, current-use, and associated variables. Using multivariable logistic regression, we analyse the increase in e-cigarette use and socio-demographic, personal, peer and familial associations, focusing on gender differences.

Results

E-cigarette ever-use increased from 23% in 2015 to 37% in 2019, and current-use from 10 to …

Perspectives On Computing Ethics: A Multi-Stakeholder Analysis, Damian Gordon, Ioannis Stavrakakis, Paul J. Gibson, Brendan Tierney, Anna Becevel, Andrea Curley, Michael Collins, William O'Mahony, Dympna O'Sullivan

Articles

Purpose:

Computing ethics represents a long established, yet rapidly evolving, discipline that grows in complexity and scope on a near-daily basis. Therefore, to help understand some of that scope it is essential to incorporate a range of perspectives, from a range of stakeholders, on current and emerging ethical challenges associated with computer technology. This study aims to achieve this by using, a three-pronged, stakeholder analysis of Computer Science academics, ICT industry professionals, and citizen groups was undertaken to explore what they consider to be crucial computing ethics concerns. The overlap between these stakeholder groups are explored, as well as whether …

Punnett Square Or Protein Production? The Expert-Novice Divide For Conceptions Of Genes And Gene Expression, Dina L. Newman, Aeowynn Coakley, Aidan Link, Korinne Mills, Leslie Kate Wright

Articles

Concepts of molecular biology and genetics are difficult for many biology undergraduate students to master yet are crucial for deep understanding of how life works. By asking students to draw their ideas, we attempted to uncover the mental models about genes and gene expression held by biology students (n = 23) and experts (n = 18) using semistructured interviews. A large divide was identified between novice and expert conceptions. While experts typically drew box-and-line representations and thought about genes as regions of DNA that were used to encode products, students typically drew whole chromosomes rather than focusing on gene structure …

The Promise And Limits Of Lawfulness: Inequality, Law, And The Techlash, Salomé Viljoen

Articles

In response to widespread skepticism about the recent rise of “tech ethics”, many critics have called for legal reform instead. In contrast with the “ethics response”, critics consider the “lawfulness response” more capable of disciplining the excesses of the technology industry. In fact, both are simultaneously vulnerable to industry capture and capable of advancing a more democratic egalitarian agenda for the information economy. Both ethics and law offer a terrain of contestation, rather than a predetermined set of commitments by which to achieve more democratic and egalitarian technological production. In advancing this argument, the essay focuses on two misunderstandings common …

Voices From A Prison Pandemic: Lives Lost From Covid-19 At Lakeland Correctional, Kimberly Thomas

Articles

Coronavirus tore through jails and prisons like wildfire. In some states, more than half of the people incarcerated there tested positive for COVID-19; nearly 400,000 people in prison across the United States have tested positive. For people in prison, COVID-19 brought the loss of close friends, solitary confinement, loss of connection with family and programming, lack of information, and fear of contracting the virus. It has also reminded those who are incarcerated of the one-dimensional way in which people in prison are perceived. As stated by one collaborator, Cory Souders, "[s]o many men and women who come to prison are …

The Mysterious Market For Post-Settlement Litigant Finance, Ronen Avraham, Lynn A. Baker, Anthony J. Sebok

Articles

Litigant finance is a growing and increasingly controversial industry in which financial firms advance a plaintiff money in exchange for ownership rights in the proceeds of the legal claim on a nonrecourse basis: A plaintiff must repay the advance only if compensation is ultimately received for the legal claim. The nonrecourse nature of this funding exempts it from most states’ consumer credit laws, enabling funders to charge higher interest and fees than would otherwise be permitted. When this funding involves ordinary consumers, critics of the industry contend that the uncapped interest rates exploit vulnerable litigants, while its defenders argue that …

How Irish Food Criticism Reflected And Helped Shape A Changing Nation, 1988-2008, Diarmuid Cawley, Claire O' Mahony

Articles

The perception and practice of eating out are linked to larger socioeconomic patterns. Newspaper restaurant reviews provide evidence of these trends which can be traced along a specific timeline. The early 1980s in Ireland were a difficult time for restaurants due to high taxes on food, a national recession and a lack of positive restaurant reviews. The economic upturn in the following decade contributed to unprecedented developments in the restaurant industry. Dining out became a regular activity – fueled in part by restaurant criticism by Irish food journalists, which joined pre-existing theatre, music and book reviews as regular features in …

‘Gilded Gravel In The Bowl’: Ireland’S Cuisine And Culinary Heritage In The Poetry Of Seamus Heaney, Anke Klitzing

Articles

Seamus Heaney’s poetry is rich in detail about agricultural and food practices in his native Northern Ireland from the 1950s onwards, such as cattle-trading, butter-churning, eel-fishing, blackberry-picking or home-baking. Often studied from an ecocritical perspective, the abundance of agricultural and culinary scenes in Heaney’s work makes a gastrocritical focus on food and foodways suitable. Food has been recognized as a highly condensed social fact, and writers have long tapped into its multi-layered meanings to illuminate socio-cultural circumstances, making literature a valuable ethnographic source. A gastrocritical reading of Heaney’s work from 1966 to 2010, drawing on Rozin’s Structure of Cuisine, shows …

Teenagers’ Moral Advertising Literacy In An Influencer Marketing Context, Emma Sweeney, Margaret-Anne Lawlor, Mairead Brady

Articles

Teenagers are avid consumers of social media and also constitute attractive target audiences for influencer marketing (IM). Teenagers can perceive strong, parasocial relationships with influencers, frequently regarding them as being akin to a peer or a friend. Furthermore, influencer endorsements are observed to carry greater credibility and authenticity than traditional forms of advertising. This therefore raises questions about young consumers’ discernment of, and critical evaluation of the overall appropriateness when influencers act as conduits of commercial messages on behalf of brands. This paper reports on a qualitative study of 29 teenagers aged 15–17 years. The aim was to explore the …

Flesh And Circuit: Rethinking Performance And Technology, Conor Mcgarrigle, E L. Putnam

Articles

The live, embodied, material, and interactive qualities of performance have made it a notable means of exploring the creative potential of technological engagement, acting as a critical vector for revealing and resisting the technological colonisation of everyday life. The innovative collaborations of Experiments in Art and Technology (EAT) during the 1960’s with artists such as Yvonne Rainer and Robert Rauschenberg, Stelarc’s extreme body modifications, Dumb Type’s intermedia performance, and Guillermo Gomez-Pena and La Pocha Nostra’s poetic and speculative imaginings, have mapped the advances in technology and opened new creative fields to explore embodiment. However, there are still some significant oversights …

Pandemic Transformation Of Teaching And Learning: Designing Pedagogy Using The Contents Of Instructors’ “Pedagogical Pantry,” Rather Than “Established Recipes.”, Sara Schley, Carol E. Marchetti

Articles

How can faculty successfully shift from a physical classroom environment to creating meaningful online learning experiences in the midst of a pandemic? Using a “kitchen pantry” metaphor, this essay suggests faculty use a “what’s in my pantry?” approach, rather than trying to replicate the in-class experience and following a previously identified “recipe.” Some faculty embrace new technology options with great gusto. Others are resistant; and still others wait until they’ve seen others use it first to consider incorporating it. This model allows for different entry points of interaction, and for different levels of experimentation, reflecting individual faculty’s strengths and capabilities. …

Locating Identities In Time: An Examination Of The Impact Of Temporality On Presentations Of The Self Through Location-Based Social Networks, Konstantinos Papangelis, Ioanna Lykourentzou, Vassilis-Javed Khan, Alan Chamberlain, Ting Cao, Micahel Saker, Nicolas Lalone

Articles

Studies of identity and location-based social networks (LBSN) have tended to focus on the performative aspects associated with marking one’s location. Yet, these studies often present this practice as being an a priori aspect of locative media. What is missing from this research is a more granular understanding of how this process develops over time. Accordingly, we focus on the first six weeks of 42 users beginning to use an LBSN we designed and named GeoMoments. Through our analysis of our users' activities, we contribute to understanding identity and LBSN in two distinct ways. First, we show how LBSN users …

Biochemical Impact Of Solar Radiation Exposure On Human Keratinocytes Monitored By Raman Spectroscopy; Effects Of Cell Culture Environment, Ulises Lopez Gonzalez, Alan Casey, Hugh Byrne

Articles

Understanding and amelioration of the effects of solar radiation exposure are critical in preventing the occurrence of skin cancer. Towards this end, many studies have been conducted in 2D cell culture models under simplified and unrealistic conditions. 3D culture models better capture the complexity of in vivo physiology, although the effects of the 3D extracellular matrix have not been well studied. Monitoring the instantaneous and resultant cellular responses to exposure, and the influence of the 3D environment, could provide an enhanced understanding of the fundamental processes of photocarcinogenesis. This work presents an analysis of the biochemical impacts of simulated solar …

Antiracist Remedial Approaches In Judge Gregory’S Jurisprudence, Leah M. Litman

Articles

This piece uses the idea of antiracism to highlight parallels between school desegregation cases and cases concerning errors in the criminal justice system. There remain stark, pervasive disparities in both school composition and the criminal justice system. Yet even though judicial remedies are an integral part of rooting out systemic inequality and the vestiges of discrimination, courts have been reticent to use the tools at their disposal to adopt proactive remedial approaches to address these disparities. This piece uses two examples from Judge Roger Gregory’s jurisprudence to illustrate how an antiracist approach to judicial remedies might work.
