Recent Advances In Luminescence And Lasing Research In Zbya Glass, Changjun Xu, Jiquan Zhang, Mo Liu, Haiyan Zhao, Fengzi Ling, Shijie Jia, Gerald Farrell, Shunbin Wang, Pengfei Wang

Articles

In the last few decades, fluoride glasses have attracted a growing interest due to their unique advantages compared to multi-component oxide glasses. Among them, the most studied and widely used were fluorozirconate glasses, represented by ZrF4–BaF2–LaF3–AlF3–NaF (ZBLAN) glasses. However, compared with ZBLAN glasses, a kind of fluorozirconate glass with the components ZrF4–BaF2–YF3–AlF3 (ZBYA) has higher thermal and chemical stability. In this paper, we first introduce the advantages of ZBYA glasses compared to ZBLAN glasses. Then we review and discuss recent advances in research on luminescence and lasing in ZBYA glass and fiber. These studies suggest that ZBYA glass has strong …

Science And Hurling: A Review, Kieran Collins, Thomas Reilly, Shane Malone, John Keane, Dominic Doran

Articles

Hurling is one of the world’s fastest field sports. Since the last review of science and Gaelic sports in 2008, there has been an increase in sports science provisions across elite and sub-elite cohorts, resulting in increased hurling-specific literature equating to an additional 111 research investigations into the game across all sports science disciplines. The present review aims to provide an updated analysis of the current research on the game and propose recommendations for future research. Overall, intermittent aerobic fitness remains an important physical quality during competition, with a focus on games-based training methodologies within the literature. Within the current …

A Systematic Review Of The Provision Of Sexuality Education To Student Teachers In Initial Teacher Education, Aisling Costello, Catherine Maunsell, Claire Cullen, Ashling Bourke

Articles

Teachers, and their professional learning and development, have been identified as playing an integral role in enabling children and young people’s right to comprehensive sexuality education (CSE). The provision of sexuality education (SE) during initial teacher education (ITE) is upheld internationally, as playing a crucial role in relation to the implementation and quality of school-based SE. This systematic review reports on empirical studies published in English from 1990 to 2019. In accordance with the PRISMA guidelines, five databases were searched: ERIC, Education Research Complete, PsycINFO, Web of Science and MEDLINE. From a possible 1,153 titles and abstracts identified, 15 papers …

Inheriting Citizenship, Scott Titshaw

Articles

Most of us become citizens at birth based either on our birthplace or our parents' citizenship status. Over thirty countries recognize birthplace citizenship, but inherited citizenship is nearly universal. Such universal legal rules are rare, and they are particularly remarkable in the context of citizenship, where state sovereignty is near its apex. This Article explores why inherited citizenship is necessary, even in nations recognizing birthplace citizenship. It surveys the history, definitions, purposes, current rules, politics, and global trends in this area and identifies three modern categories of birthright citizenship laws: primary inherited citizenship systems, dual inherited and birthplace systems, and …

Encapsulation Of Essential Oils In Nanocarriers For Active Food Packaging, Shubham Sharma, Lilly Mulrey, Megan Byrne, Amit Jaiswal, Swarma Jaiswal

Articles

Active packaging improves a packaging system’s effectiveness by actively integrating additional components into the packaging material or the headspace around the packaging. Consumer demand and awareness have grown enough to replace chemical agents with natural active agents. Essential oils (EOs) are extensively distributed throughout nature but at low levels and sometimes with poor recovery yields, which poses an issue with their application in food. Due to the instability of EOs when added directly into a food product, they require encapsulation before being added to a packaging matrix such as liposomes, solid-lipid nanoparticles, nano-emulsions, cyclodextrins, and nanostructured lipid nano-carriers. This article …

Website Builders Still Contribute To Inaccessible Web Design, Athira Pillai, Kristen Shinohara, Garreth W. Tigwell

Articles

Website builders enable individuals without design or technical skills to create websites. However, it is unclear if modern websites created by website builders meet accessibility standards. We reviewed six popular website building platforms and found a lack of accessibility support. Wix provided the most comprehensive accessibility documentation and robust accessibility features. However, during an accessibility audit of 90 Wix webpages, we found many accessibility issues, raising concerns about how users are supported.

Micro-Rna And Proteomic Profiles Of Plasma-Derived Exosomes From Irradiated Mice Reveal Molecular Changes Preventing Apoptosis In Neonatal Cerebellum, Simonetta Pazzaglia, Barbara Tanno, Ilaria De Stefano, Paola Giardullo, Simona Leonardi, Caterina Merla, Gabriele Babini, Seda Tuncay Cagatay, Ammar Mayah, Munira Kadhim, Fiona Lyng, Christine Von Toerne, Zohaib N. Khan, Prabal Subedi, Soile Tapio, Anna Saran, Mariateresa Mancuso

Articles

Cell communication via exosomes is capable of influencing cell fate in stress situations such as exposure to ionizing radiation. In vitro and in vivo studies have shown that exosomes might play a role in out-of-target radiation effects by carrying molecular signaling mediators of radiation damage, as well as opposite protective functions resulting in resistance to radiotherapy. However, a global understanding of exosomes and their radiation-induced regulation, especially within the context of an intact mammalian organism, has been lacking. In this in vivo study, we demonstrate that, compared to sham-irradiated (SI) mice, a distinct pattern of proteins and miRNAs is found …

A Knowledge-Based Model For Context-Aware Smart Service Systems, Thang Le Dinh, Thanh Thoa Pham Thi, Cuong Pham-Nguyen, Le Nguyen Hoai Nam

Articles

The advancement of the Internet of Things, big data, and mobile computing leads to the need for smart services that enable the context awareness and the adaptability to their changing contexts. Today, designing a smart service system is a complex task due to the lack of an adequate model support in awareness and pervasive environment. In this paper, we present the concept of a context-aware smart service system and propose a knowledge model for context-aware smart service systems. The proposed model organizes the domain and context-aware knowledge into knowledge components based on the three levels of services: Services, Service system, …

Transferring Studies Across Embodiments: A Case Study In Confusion Detection, Na Li, Robert J. Ross

Articles

Human-robot studies are expensive to conduct and difficult to control, and as such researchers sometimes turn to human-avatar interaction in the hope of faster and cheaper data collection that can be transferred to the robot domain. In terms of our work, we are particularly interested in the challenge of detecting and modelling user confusion in interaction, and as part of this research programme, we conducted situated dialogue studies to investigate users' reactions in confusing scenarios that we give in both physical and virtual environments. In this paper, we present a combined review of these studies and the results that we …

Advancing Competency In Managing Risk And Knowledge: Steps Toward Operationalisation Of The Risk-Knowledge Infinity Cycle (Rki Cycle) Part 3: Uncovering Knowledge For Qrm Through Knowledge Mapping At Node 1, Martin Lipa, Valerie Mulholland, Anne Greene

Articles

To date, literature on the Risk-Knowledge Infinity Cycle (RKI Cycle) has mainly been theoretical. This paper series intent is to focus on the operationalisation of the RKI Cycle by describing a series of steps – the “How to” – for RKI Cycle deployment, to help move the RKI Cycle from theory to practice. The third paper in this series focuses on ensuring the best available knowledge flows into QRM through a case study demonstrating knowledge mapping to support effective quality risk assessment during commissioning and qualification activities.

Mirna-Mediated Fibrosis In The Out-Of-Target Heart Following Partial-Body Irradiation, Barbara Tanno, Flavia Novelli Flavia Novelli, Simona Leonardi, Caterina Merla, Gabriele Babini, Paola Giardullo, Munira Kadhim, Damian Traynor, Dinesh Medipally, Aidan Meade, Fiona Lyng, Soile Tapio, Luca Marcetti, Anna Saran, Simonetta Pazzaglia, Mariateresa Mancuso

Articles

A causal association between radiation exposure and various types of non-malignant diseases, especially cardiovascular diseases, has been extensively reported [1,2]. The risks of radiation-induced heart disease (RIHD) were described in therapeutically exposed cohorts of patients with thoracic tumors in which a high incidence of long-term complications (i.e., pericarditis, cardiomyopathy, coronary artery disease, valvular heart disease, conduction abnormalities and myocardial fibrosis) increased the risk of heart-disease-related mortality [3]. Patients who received post-mastectomy radiotherapy for left-sided breast cancer were at a 2–3-time higher risk of developing cardiovascular disease, due to the apex and anterior wall of the heart being exposed to doses …

The Epistemology Of The Internet And The Regulation Of Speech In America, Brian Leiter

Articles

The Internet is the epistemological crisis of the 21st century: it has fundamentally altered the social epistemology of societies with relative freedom to access it. Most of what we think we know about the world is due to reliance on epistemic authorities, individuals, or institutions that tell us what we ought to believe about Newtonian mechanics, evolution by natural selection, climate change, resurrection from the dead, or the Holocaust. The most practically fruitful epistemic norm of modernity, empiricism, demands that knowledge be grounded in sensory experience, but almost no one who believes in evolution by natural selection or the reality …

Duplicative Taxation Among The States: A Problem Not Worth Solving?, Julie Roin

Articles

Recent legal and economic changes not to mention the rise in telecommuting caused by COVID have raised the salience of a lon-simmering fact about the operation of state and local income tax systems: some multistate employers and employees pay a combined income tax liability that is higher than the tax they would have borne had they operated in just one jurisdiction. Seemingly beyond the reach of the courts to correct, there have been persistent calls for congressional action to eliminate or reduce this "duplicative" taxation. This Article suggests that the alleged problem may be both less of a problem, and …

Hidden Agendas In Shareholder Voting, Scott Hirst, Adriana Z. Robertson

Articles

Nothing in either corporate or securities law requires companies to notify investors what they will be voting on before the record date for a shareholder meeting. We show that, overwhelmingly, they do not. The result is “hidden agendas”: for 88% of shareholder votes, investors cannot find out what they will be voting on before the record date. This poses an especially serious problem for investors who engage in securities lending: they must decide whether the expected benefit of voting exceeds the expected benefit of continuing to lend their shares (or making them available for lending) without knowing what they will …

The 4c’S Of Pal – An Evidence-Based Model For Implementing Peer Assisted Learning For Mature Students, Nevan Bermingham, Frances Boylan, Barry J. Ryan

Articles

Peer Assisted Leaning (PAL) programmes have been shown to enhance learner confidence and have an overall positive effect on learner comprehension, particularly in subjects traditionally perceived as difficult. This research describes the findings of a three-cycle Action Research study into the perceived benefits of implementing such a programme for mature students enrolled on a computer science programming module on an Access Foundation Programme in an Irish University. The findings from this study suggest that peer learning programmes offer students a valued support structure that aids transition and acculturation into tertiary education whilst simultaneously improving their subject-matter comprehension and confidence. An …

Digital Accessibility In Iran: An Investigation Focusing On Iran's National Policies On Accessibility And Disability Support, Laleh Nourian, Kristen Shinohara, Garreth W. Tigwell

Articles

Digital accessibility has become an important topic in the field of HCI, but when looking at accessibility on a global scale, we find that the representation of accessibility research is mostly centered in the Global North with countries that are WEIRD (Western, Educated, Industrialized, Rich, and Democratic). Our paper explores digital accessibility in Iran, focusing exclusively on its national policies on accessibility. Iran is a non-WEIRD country located in the Global South, with no reports on its digital accessibility status from the Global Initiative for Inclusive Information and Communication Technologies (G3ict). We found that there is not enough focus on …

Feminist Ethics And Research With Women In Prison, Christina Quinlan, Lucy Baldwin, Natalie Booth

Articles

In this article, a new model, An Ethic of Empathy, is proposed as a guide for researchers, particularly new scholars to the discipline. This model emerged from the authors’ concerns regarding the application of ethics to studies that focus on the experience of female offenders in criminal justice systems. The key issue is the vulnerability of incarcerated and post-release women in relationship to the powerful status of social scientist researchers. The complexity of ethics in such research settings necessitates a particular ethical preparation, involving formation, reflection, understanding, commitment, care, and empathy. Three cases are outlined which document the authors’ ethical …

The Impact Of R&D Innovation Success On The Relationship Between R&D Investment And Financial Leverage, Vincent O’Connell, Naser Abughazaleh, Yasean Tahat, Garvan Whelan

Articles

This paper explores the interrelationship between R&D investment, financial leverage, and a firm’s R&D innovation success. Using a sample of UK and EU firms, we predict that changes in oneyear- ahead R&D investment are negatively associated with changes in financial leverage in the current period. Crucially, we also predict that this negative association is positively moderated by the extent to which firms are successful in generating commercially viable and technically feasible innovations from their R&D work. We use insights from International Accounting Standard (IAS) 38: Intangible Assets to measure R&D innovation success. Our empirical findings offer strong support for each …

Reasoning V. Rhetoric: The Strange Case Of “Unconstitutional Beyond A Reasonable Doubt”, Hugh D. Spitzer

Articles

An odd formulation has frequented American constitutional discourse for 125 years: a declaration that courts should not overturn a statute on constitutional grounds unless it is “unconstitutional beyond a reasonable doubt.” This concept has been thought of as a presumption, a standard, a doctrine, or a philosophy of coordinate branch respect and judicial restraint. Yet it has been criticized because “beyond a reasonable doubt” is at root an evidentiary standard of proof in criminal cases rather than a workable theory or standard for deciding constitutional law cases. This article discusses the history and use of “unconstitutional beyond a reasonable doubt,” …

Inclusion And Belonging In Irish Higher Education For Black And Minority Ethnic Students., Fionnuala Darby

Articles

Using Critical Race Theory (CRT) as an analytical prism, this study interrogates the sense of belonging and inclusion experienced by Black and Minority Ethnic (BME) students on one higher education campus in Ireland. The most important story told within the study is as simple as it is complicated. The simple part is that the BME students felt that the campus was inclusive and that they experienced a sense of belonging. The complicated part is that the findings are premised in a normative assumption of whiteness as evidenced by numerous and incremental moments of exclusion in the daily experience of microaggressions, …

The Expanding Universe Of Bilateral Labor Agreements, Adam Chilton, Bartosz Woda

Articles

In the seventy-five years since the end of World War II, pairs of countries have entered into over a thousand bilateral labor agreements (BLAs) to regulate the cross-border flow of workers. These agreements have received little public or academic attention. This is likely, in part, because there is limited data or easily available information on BLAs. This Article hopes to change that by introducing three new resources: (1) a dataset documenting the formation of over 1,200 BLAs; (2) a corpus including the texts of over 800 BLAs; and (3) a dataset coding whether over 500 BLAs mention twenty topics that …

Constitutional Challenges To Public Health Orders In Federal Courts During The Covid-19 Pandemic, Kenny Mok, Eric A. Posner

Articles

We examine federal judicial cases involving nonreligious civil-liberties challenges to COVID-19-related public health orders from the start of the pandemic in early 2020 to January 27, 2022. Consistent with the tradition of judicial deference toward states during emergencies, we find a high level of success for governments. However, governments did lose in 14.2% of the cases, and in those losses, there is evidence of partisan or ideological influence. Republican-appointed judges were more likely to rule in favor of challengers who brought claims based on gun rights and property rights, while Democratic- appointed judges were more likely to rule in favor …

Police Agencies On Facebook Overreport On Black Suspects, Ben Grunwald, Julian Nyarko, John Rappaport

Articles

A large and growing share of the American public turns to Facebook for news. On this platform, reports about crime increasingly come directly from law enforcement agencies, raising questions about content curation. We gathered all posts from almost 14,000 Facebook pages maintained by US law enforcement agencies, focusing on reporting about crime and race. We found that Facebook users are exposed to posts that overrepresent Black suspects by 25 percentage points relative to local arrest rates. This overexposure occurs across crime types and geographic regions and increases with the proportion of both Republican voters and non-Black residents. Widespread exposure to …

Regulatory Diffusion, Jennifer Nou, Julian Nyarko

Articles

Regulatory diffusion occurs when an agency adopts a substantially similar rule to that of another agency. Indeed, regulatory texts proliferate just like other forms of law do. While this insight has been explored across countries, this dynamic also occurs closer to home: American administrative agencies regularly borrow language from one another. Our research shows that, in recent years, agencies reused one out of every ten paragraphs of the Code of Federal Regulations. These findings are timely given the Supreme Court’s call for judges to be less deferential to agency regulatory interpretation. There is thus newfound significance to understanding how legislative …

Not-For-Profits, Esgs, And The Economic Structure Of Corporate Law, Saul Levmore

Articles

A compelling point in The Economic Structure of Corporate Law is that the single goal of maximizing shareholder value is efficient and generally desirable because it gives the managers one aim—while leaving room for law and private contracts to impose constraints on the firm in order to control negative externalities and other social concerns. Easterbrook and Fischel say that: “A manager told to serve two masters (a little for the equity holder, a little for the community) has been freed of both and is answerable to neither.” The point is an especially good one when the manager has more of …

English Common Law And The Ius Commune: The Contributions Of An English Civilian, R. H. Helmholz

Articles

Any student of legal history who believes that the European ius commune played a meaningful part in the origins and development of English law will profit from reading Reinhard Zimmermann’s masterpiece, The Law of Obligations. Indeed, that student will read it with joy. I am one of that number, and I remember my own reaction well when his book first appeared—equal parts of admiration and encouragement. Not only was the book a sparkling and learned treatment of many important aspects of the civil law, subjects about which I needed to learn more, it also proved to be the source of …

Open Access, Interoperability, And Dtcc’S Unexpected Path To Monopoly, Dan Awrey, Joshua C. Macey

Articles

For markets characterized by significant economies of scale, scholars and policy- makers o�en advance open-access and interoperability requirements as superior to both regulated monopoly and the breakup of dominant firms. In theory, by compelling firms to coordinate in the development of common infrastructure, these requirements can replicate the advantages of scale without leaving markets vulnerable to monopoly power. Examples of successful coordination include the provision of electricity, intermodal transportation, and credit-card networks.

This Article offers a qualification to this received wisdom. By tracing the Depository Trust and Clearing Corporation’s path to monopoly in the U.S. securities clearing and depository markets, …

Will Competition Reduce Attention Costs In Social Media?, Francesco Parisi

Articles

Unlike other monopolies, social media networks almost uniformly give access to their services for free to everybody. Economists refer to these markets as “zero-price markets.” The main, and often sole, source of revenue for the network owners comes from fees that are paid by advertisers. Network owners offer access to users in exchange for users’ attention to advertisements. Economists refer to these implicit market exchanges under the heading of “attention economy.” Regulatory solutions and antitrust remedies have been considered to foster cost reduction in the market economy. This paper investigates the conditions under which an increase in competition in the …
