Modified Surface Relief Layer Created By Holographic Lithography: Application To Selective Sodium And Potassium Sensing, Sabad-E Gul, Luke O'Neill, John Cassidy, Izabela Naydenova

Articles

Point-of-care diagnostics will rely upon the development of low-cost, noncomplex, and easily integrated systems in order to examine biological samples such as blood and urine obtained from the patient. The development of metal ion sensors is a subject of significant relevance for physiological samples. The level of different blood electrolytes, mainly H+, Na+, K+ and Cl− is considerably used to monitor irregular physiologies. The particular challenge in biosensing, and in fact for any other sensor, is signal differentiation between non-specifically bound material and the specific detecting of the target molecule/ion. The biosensors described in this paper are fabricated by a …

Nanomole Silver Detection In Chloride-Free Phosphate Buffer Using Platinum And Gold Micro- And Nanoelectrodes, Prabhakar Sidambaram, John Colleran

Articles

The electrochemical determination of ultra-low concentrations of silver requires reliable, reproducible measurements using sensitive analytical techniques. To date, the electrochemical determination of silver in biological buffers and pH neutral media has not been successful in terms of reproducibility. In this work, we report on the determination of ultra-low concentrations of silver in chloride-free phosphate buffer solution (PB, pH 7.4). Detection was conducted at gold and platinum micro and nanoelectrodes using anodic stripping voltammetry (ASV). The micro and nanoelectrodes were fabricated using a Sutter P-2000 laser puller, with physical and electrochemical characterization revealing flat disk-shaped working surfaces of 10–15 μm (microelectrode) …

Evaluation Of Silver Nanoparticle Encapsulation In Dppc-Based Liposome By Different Methods For Enhanced Cytotoxicity, Azeez O. Yusef, Alan Casey

Articles

Here we carried out a comparative study on two cost and time effective methods of encapsulating silver nanoparticles (AgNP) in dipalmitoyl-phosphatidyl choline (DPPC)/cholesterol-based liposome to enhance nanoparticle cytotoxicity, and evaluated the effect of this on a blood cell line (THP1 monocytes) often involved in uptake of nanoparticles during human exposure. DLS and Zeta potential analyses over a 6-months period showed the extruded Lipo-AgNP (Ex-Lipo-AgNP) exhibited more stable characteristics when compared with the probe-sonicated Lipo-AgNP (PB-Lipo-AgNP). SEM microscopy indicated agglomeration of the PB-Lipo-AgNP which was not observed in Ex-Lipo-AgNP. Ex-Lipo-AgNP also exhibited higher temperature-dependent stability with 35.3% reduction in size from …

Nuclear Frames In The Irish Media: Implications For Conversations On Nuclear Power Generation In The Age Of Climate Change, Catherine Devitt, Finbarr Brereton, Simon Mooney, David Conway, Eoin O'Neill

Articles

Keeping within the temperature limits set by the Paris Agreement on climate action will be a significant challenge. Nuclear power generation may contribute to achieving these targets, however, there are significant environmental, economic and health risks attached. Using qualitative and quantitative methods, this paper explores how nuclear power generation is framed in the Irish print media, and discusses the implications of these frames for how nuclear power is perceived within the context of climate change mitigation in Ireland. Two Irish broadsheet papers, the Irish Times and the Irish Independent were selected for data collection, focusing on Chernobyl and Fukushima incidents. …

Parental Mediation And The Internet: Findings Of Net Children Go Mobile For Parents' Mediation Strategies In Ireland: Mediazione Dei Genitori E Internet: Risultati Di Net Children Go Mobile Per Le Strategie Di Mediazione Di Genitori In Irlanda., Thuy Dinh, Brian O'Neill

Articles

Based on data collected from the Net Children Go Mobile project, a cross- national study of children aged 9-16 in seven European countries with a focus on the Irish context, this article examines parental mediation of children’ online ac- tivities. The relationship between children’s digital skills (including internet and smartphone use) and parental mediation is also examined and factors influenc- ing parent mediation are highlighted. Parents implement a range of strategies, favouring strict mediation and rules over active mediation on internet safety, but these were associated with reduced children’s online activities and digital skills. These findings challenge researchers to identify …

Cooking A Corporation Tax Controversy: Apple, Ireland And The Eu., Ciara Graham, Brendan O'Rourke

Articles

Given the centrality of corporations in distribution of income and wealth studies, discursive constructions of corporate taxation are essential to understanding the production of inequality. The focus of this study is an interview with Apple’s Chief Executive Tim Cook on the Irish state broadcaster, Raidió Teilifís Éireann’s (RTÉ) flagship news programme, Morning Ireland, following the ruling by the European Commission (EC) on the corporation tax arrangements between Apple Inc. and Ireland. Drawing on a Critical Discourse Analysis (CDA) approach, a frame analysis is provided. The significance and extent of the EC’s ruling has potential implications for corporation taxation policy, within …

The Bullet In The Brick: The Materiality Of Conflict In Museum Objects, Siobhan Doyle

Articles

Tangible traces of conflict in visual artefacts can take viewers uncomfortably close to the realities of war—violence, destruction and fatalities. This article questions the evidential force of objects associated with conflict and their eventual display in exhibitions. Through a study of the display of a brick in which is embedded a bullet that is said to have passed through the body of Francis Sheehy Skeffington when he was executed by firing squad during the Easter Rising in Dublin in 1916, this article explores the historical configuration of the brick and analyses its public display in the National Museum of Ireland …

Traversing States: A Reflection On Digital Technology And Simondon's Critique Of Hylomorphism, Michael O'Hara

Articles

In this article, I examine Simondon's concept of the technical object reflecting on its analogous relationship to digital technology. Intrinsic to such an analysis is Simondon's distinction between the abstract and concrete and his specific critique of the hylomorphic model. In a deeply rich example, Simondon, contra Aristotle, mobilises the process of mould-making as an exemplar of the modulated ensemble of forces that prefigure any formations of matter through form. I analyse Simondon's paradigmatic criticism while at the same time carving out the potential intersections that emerge through the kinaesthetic awareness of the body. By doing so I highlight the …

Calculating Restaurant Failure Rates Using Longitudinal Census Data, J. J. Healy, Máirtín Mac Con Iomaire

Articles

Failure rates in the restaurant industry are popularly perceived to be far higher than they actually are. This paper calculates failure rates in the Irish Food and Drinks Sector (IFDS), for the first time, using longitudinal census data from the Central Statistics Office (CSO) in Ireland, which follows the European statistical classification of economic activity (NACE). The results are compared with previously published literature on restaurant failure rates in the United States of America. This study also compares IFDS failure rates with other industry sectors in Ireland (construction, manufacturing). Drawing on Stinchcombe’s ’liability of newness’ theory, the informal fallacies theory …

Results: 17,433 articles were identified and 130 experiments from 128 studies were included. Retrieved …

Nanostructured Materials For Food Applications: Spectroscopy, Microscopy And Physical Properties, Shubham Sharma, Swana Jaiswal, Brendan Duffy, Amit Jaiswal

Articles

Nanotechnology deals with the matter of atomic or molecular scale. Other factors that define the character of a nanoparticle are its physical and chemical properties, such as surface area, surface charge, hydrophobicity of the surface, the thermal stability of the nanoparticle, and its antimicrobial activity. A nanoparticle is usually characterized by using microscopic and spectroscopic techniques. Microscopic techniques are used to characterize the size, shape, and location of the nanoparticle by producing an image of the individual nanoparticle. Several techniques, such as scanning electron microscopy (SEM), transmission electron microscopy/high resolution transmission electron microscopy (TEM/HRTEM), atomic force microscopy (AFM) and scanning …

A Multilayer Exponential Random Graph Modelling Approach For Weighted Networks, Alberto Caimo, Isabella Gollini

Articles

A new modelling approach for the analysis of weighted networks with ordinal/polytomous dyadic values is introduced. Specifically, it is proposed to model the weighted network connectivity structure using a hierarchical multilayer exponential random graph model (ERGM) generative process where each network layer represents a different ordinal dyadic category. The network layers are assumed to be generated by an ERGM process conditional on their closest lower network layers. A crucial advantage of the proposed method is the possibility of adopting the binary network statistics specification to describe both the between-layer and across-layer network processes and thus facilitating the interpretation of the …

Devereux Jennings, Samina Karim, Aseem Kaul, Sergio Lazzarini, Banu Ozkazanc-Pan, Paul Donnelly, Andreas Rasche, Anne S. Tsui, Thomas A. Wright, Todd R. Zenger

Articles

Organization design seeks to balance potentially conflicting objectives while achieving a broader mission. EO13769 created a challenge for the president of the Academy of Management in leading through these conflicts, as President Anita McGahan describes: how to be true to her own moral values while leading an organization with well-established design constraints, and members with diverse opinions. This article shares the perspectives of 12 scholars on the lessons we can learn from Professor McGahan’s leadership of a constraining organization through a challenging time.

The Moderation Effect Of Social Factors On Marketing Factors In Consumer Research, Xiaochuang Wu, Helen Chen, Xiaohong Li

Articles

Consumer research tends to isolate the impact of marketing and social factors. Little has been done to include both. This paper aimed to find out what would happen when these two sets of factors are included. Two models were built in this paper, Model I with the marketing factors only and Model II with both the marketing and social factors. Data was collected in Ireland among more than 1473 transition year students in a personal survey regarding their willingness to learn Chinese. Data were analysed by using structural equation modelling (SEM). Results showed the two social variables, acculturation and intergenerational …

How U.S. Family Law Might Deal With Spousal Relationships Of Three (Or More) People, Edward D. Stein

Articles

For much of this nation's history, the vast majority of people have believed that being married to more than one person at the same time is deeply problematic. Further, polygamous marriage has never been legal in the United States. Despite this, some people have been in plural or group relationships and some of these people have wished to gain legal recognition for these relationships. The arguments for recognizing such relationships are persuasive, but the prospects for legalization of polygamous marriage seem slim in the near future. This Article offers a suggestion of how the law of domestic relations might deal …

Community Consequences Of Airbnb, Allyson E. Gold

Articles

Short-term rental accommodations account for more than 20% of the United States lodging market, with annual sales now greater than those of nearly all legacy hotel brands. The rise of companies like Airbnb has created a booming market that provides affordable short-term rentals for travelers and new income for those with an extra couch, spare room, or even an unused home. However, while individual hosts and guests may benefit economically, the use of short-term rentals produces significant consequences for the surrounding community. Airbnb proliferation causes fewer affordable housing options, higher average asking rents, and erosion of neighborhood social capital. Due …

The Case Against Expanding Defamation Law, Yonathan A. Arbel, Murat Mungan

Spheroid-3d And Monolayer-2d Intestinal Electrochemical Biosensor For Toxicity/Viability Testing: Applications In Drug Screening, Food Safety, And Environmental Pollutant Analysis, Evangelia Flampouri, Shahzad Imar, Kieran O'Connell, Baljit Singh

Articles

The rise of three-dimensional cell culture systems that provide in vivo-like environments for pharmaco-toxicological models has prompted the need for simple and robust viability assays suitable for complex cell architectural structures. This study addresses that challenge with the development of an in vitro enzyme based electrochemical sensor for viability/cytotoxicity assessment of two-dimensional (2D) monolayer and three-dimensional (3D) spheroid culture formats. The biosensor measures the cell viability/toxicity via electrochemical monitoring of the enzymatic activity of nonspecific esterases of viable cells, through the hydrolysis of 1-naphthyl acetate to 1-naphthol. The proposed sensor demonstrated strong correlation (r = 0.979) with viable …

Home Sweet Home: How New York Courts Have Dealt With Daimler's "At Home" Requirement For General Jurisdiction, Burton N. Lipshie

Articles

In this Article, we will first place the Daimler decision in its context, both historical and technological, in an attempt to understand the flow of Supreme Court jurisdiction jurisprudence, and how Daimler fits into that jurisprudence. Then, we will explore the issues in New York law that Daimler left open, and which, more than five years after it was decided, remain open, and, indeed, often confused.

Jurisliterature And Transgression, Peter Goodrich

Articles

The jurisliterary profession is the curious enterprise of writing, as a jurist, about law. Many seek to escape into literature, philosophy, critique, psychoanalysis, the couch, but then, in the main, they have abandoned law. Those that persist, who remain jurists, have the propensity to transgress the boundaries of the juridical, the strictures of abstraction and disembodiment, so as to generate accounts of legal sensibility, so as to manifest the polyglottal and visceral potential of transforming the juridical bubble into that most ethical of realms, the poetics of desire. Jurisliterary transgression, at its strongest, returns the materiality of imagination to the …
