Mapping The Restoration Of Degraded Peatland As A Field Of Research Area: A Scientometric Review, Samuel Obeng Apori, Douglas Mcmillan, Michelle Giltrap, Furong Tian

Articles

Degraded peatland reduced many ecosystem services such as water quality and quantity, biodiversity, carbon storage, climate regulations and other cultural benefits. Therefore, several initiatives for the restoration of degraded peatland (RDP) have been attempted to restore the ecosystem processes, productivity and services of the degraded peatland to its original natural condition. Notwithstanding the popularity of RDP research among researchers and industry practitioners, a quantitative technique to map a comprehensive survey of the intellectual core and the general body landscape of knowledge on RDP research does not exist. In this study, a scientometric analysis was employed to analyze 522 documents using …

A method is proposed for recommendation of replacements for lost meaningful activities that accounts for the need to maintain activities of daily living.

Cross-Atlantic Experiments On Eu-Us Test-Beds, Sachin Sharma, Avishek Nag, Byrav Ramamurthy

Articles

Today, there are a number of real testbeds worldwide among which Fed4Fire testbeds are prominent in the EU, while POWDER and COSMOS are prominent in the US. This paper aims to validate inter-testbed experiments between the EU and the US by connecting a number of Fed4Fire and US testbeds as part of an NGIAtlantic project. The goal is to compare the hop count, the topology formed, the maximum bandwidth permitted, and the loss and jitter that occurred between different testbeds. Additionally, Software Defined Networking (SDN) experiments between EU and US testbeds are conducted, and an edge-computing use case is developed …

Scaling And Placing Distributed Services On Vehicle Clusters In Urban Environments, Kanika Sharma, Bernard Butler, Brendan Jennings

Articles

Many vehicles spend a significant amount of time in urban traffic congestion. Due to the evolution of autonomous vehicles, driver assistance systems, and in-vehicle entertainment, these vehicles have plentiful computational and communication capacity. How can we deploy data collection and processing tasks on these (slowly) moving vehicles to productively use any spare resources? To answer this question, we study the efficient placement of distributed services on a moving vehicle cluster. We present a macroscopic flow model for an intersection in Dublin, Ireland, using real vehicle density data. We show that such aggregate flows are highly predictable (even though the paths …

Governing Open Ocean And Fish Carbon: Perspectives And Opportunities, Maartje Oostdijk, Laura G. Elsler, Paulina Ramírez-Monsalve, Kirill Orach, Mary S. Wisz

Articles

Marine life plays a vital role in the ocean’s biological pump by sequestering and mediating fluxes of carbon to the deep sea and sea floor. The roles that fish and other marine vertebrates play in the biological pump are increasingly attracting scientific and policy attention. In this paper, we investigated the interest in and possibilities for the international governance of open ocean and fish carbon ecosystem services. We used semi-structured interviews with representatives from environmental non-governmental organisations (ENGOs), policy makers, and policy experts, along with an exploratory review of grey and peer-reviewed literature to: 1) trace the pathway of important …

Contributions Of Vibrational Spectroscopy To Virology: A Review, Iqra Chaudhary, Naomi Jackson, Denise Denning, Luke O'Neill, Hugh Byrne

Articles

Vibrational spectroscopic techniques, both infrared absorption and Raman scattering, are high precision, label free analytical techniques which have found applications in fields as diverse as analytical chemistry, pharmacology, forensics and archeometrics and, in recent times, have attracted increasing attention for biomedical applications. As analytical techniques, they have been applied to the characterisation of viruses as early as the 1970s, and, in the context of the coronavirus disease 2019 (COVID-19) pandemic, have been explored in response to the World Health Organisation as novel methodologies to aid in the global efforts to implement and improve rapid screening of viral infection. This review …

From Zero To Thrive: A Model Of Cross-System And Cross-Sector Relational Health To Promote Early Childhood Development Across The Child-Serving Ecosystem, Alison L. Miller, Sara F. Stein, Rebeccah Sokol, Rachel Varisco, Phoebe Trout, Megan M. Julian, Julie Ribaudo, Joshua B. Kay, Natasha V. Pilkauskas, Nicole Gardner-Neblett, Todd I. Herrenkohl, Kara Zivin, Maria Muzik, Katherine L. Rosenblum

Articles

Early relational health between caregivers and children is foundational for child health and well-being. Children and caregivers are also embedded within multiple systems and sectors, or a “child-serving ecosystem”, that shapes child development. Although the COVID-19 pandemic has made this embeddedness abundantly clear, systems remain siloed and lack coordination. Fostering relational health amongst layers of this ecosystem may be a way to systematically support young children and families who are facing adversity. We integrate theory, examples, and empirical findings to develop a conceptual model informed by infant mental health and public health frameworks that illustrates how relational health across the …

An Exploratory Study On Refactoring Documentation In Issues Handling, Eman Abdullah Alomar, Anthony Peruma, Mohamed Wiem Mkaouer, Christian D. Newman, Ali Ouni

Articles

Understanding the practice of refactoring documentation is of paramount importance in academia and industry. Issue tracking systems are used by most software projects enabling developers, quality assurance, managers, and users to submit feature requests and other tasks such as bug fixing and code review. Although recent studies explored how to document refactoring in commit messages, little is known about how developers describe their refactoring needs in issues. In this study, we aim at exploring developer-reported refactoring changes in issues to better understand what developers consider to be problematic in their code and how they handle it. Our approach relies on …

Code Review Practices For Refactoring Changes: An Empirical Study On Openstack, Mohamed Wiem Mkaouer, Eman Abdullah Alomar, Moatz Chouchen, Ali Ouni

Articles

Modern code review is a widely used technique employed in both industrial and open-source projects to improve software quality, share knowledge, and ensure adherence to coding standards and guidelines. During code review, developers may discuss refactoring activities before merging code changes in the code base. To date, code review has been extensively studied to explore its general challenges, best practices and outcomes, and socio-technical aspects. However, little is known about how refactoring is being reviewed and what developers care about when they review refactored code. Hence, in this work, we present a quantitative and qualitative study to understand what are …

Combining Pharmacokinetics And Vibrational Spectroscopy: Mcr-Als Hard-And-Soft Modelling Of Drug Uptake In Vitro Using Tailored Kinetic Constraints, David Perez-Guaita, Guillermo Quintas, Zeineb Farhane, Roma Tauler, Hugh Byrne

Articles

Raman microspectroscopy is a label-free technique which is very suited for the investigation of pharmacokinetics of cellular uptake, mechanisms of interaction, and efficacies of drugs in vitro. However, the complexity of the spectra makes the identification of spectral patterns associated with the drug and subsequent cellular responses difficult. Indeed, multivariate methods that relate spectral features to the inoculation time do not normally take into account the kinetics involved, and important theoretical information which could assist in the elucidation of the relevant spectral signatures is excluded. Here, we propose the integration of kinetic equations in the modelling of drug uptake and …

Estimating The Analytical Performance Of Raman Spectroscopy For Quantification Of Active Ingredients In Human Stratum Corneum, Hichem Kichou, Emilie Munnier, Yuri Dancik, Kamilia Kemel, Hugh Byrne, Ali Tfayli, Dominique Bertrand, Martin Soucé, Igor Chourpa, Franck Bonnier

Articles

Confocal Raman microscopy (CRM) has become a versatile technique that can be applied routinely to monitor skin penetration of active molecules. In the present study, CRM coupled to multivariate analysis (namely PLSR—partial least squares regression) is used for the quantitative measurement of an active ingredient (AI) applied to isolated (ex vivo) human stratum corneum (SC), using systematically varied doses of resorcinol, as model compound, and the performance is quantified according to key figures of merit defined by regulatory bodies (ICH, FDA, and EMA). A methodology is thus demonstrated to establish the limit of detection (LOD), precision, accuracy, sensitivity (SEN), and …

Controlling Unequal Surface Energy Results Caused By Test Liquids: The Case Of Uv/O3 Treated Pet, Bilge N. Altay, Paul D. Fleming, Md Arifur Rahman, Alexandra Pekarovicova, Bruce Myers, Cem Aydemir, Arif Karademir

Articles

Ultraviolet/ozone (UV/O3) treatment has been reported to be an effective method to modify properties such as wettability, adhesion or adsorption of plastic surfaces. The change in the surface is measured by contact angle analysis, which employs liquids and their surface tensions (ST) to estimate the surface energy (SE). We found two different practices in the scientific community: (1) the majority of researchers adopted the ST value of liquids from the literature, while (2) other researchers conducted real-time measurements in the lab under ambient conditions prior to SE estimation. To the best of our knowledge, there is no study that compares …

Integrated-Hybrid Framework For Connected And Autonomous Vehicles Microscopic Traffic Flow Modelling, Ammar Jafaripournimchahi, Yingfeng Cai, Hai Wang, Lu Sun, Jiancheng Weng

Articles

In this study, a novel traffic flow modeling framework is proposed considering the impact of driving system and vehicle mechanical behavior as two different units on the traffic flow. To precisely model the behavior of Connected and Autonomous (CA) vehicles, three submodels are proposed as a novel microscopic traffic flow framework, named Integrated-Hybrid (IH) model. Focusing on the realization of the car following behavior of CA vehicles, the driving system (vehicle control system) and the vehicle mechanical system are modeled separately and linked by throttle and brake actuators model. +e IH model constitutes the key part of the Full Velocity …

Articles

In the aftermath of COVID-19, remote working has become the norm, and graduates now need an even wider range of skills, which traditional classrooms and internships do not always provide. Working in multiple time zones, within global multi-cultural teams, and only ever meeting colleagues through online technology are just some of the challenges, which require a new type of global graduate. Transversal skills including leadership, collaboration, innovation, digital, green, organization and communication skills are critical. The disruption from COVID-19 also presents unprecedented opportunities to develop more inclusive approaches to internships and international experiences, to level the playing field for students …

Latin American Film, Mirna Vohnsen

Articles

The scholarship on Latin American film in 2020 points to a diverse and vibrant field of study that encompasses a wide range of themes. This year, the representations of indigenous peoples, as well as the studies on youth and transnationalism, have caught the attention of several scholars. Another topic that has gained importance is the revisiting of films, filmmakers, and performers from the twentieth century. Volume 17, number 2, of Studies in Spanish & Latin American Cinemas, which is devoted to Mexican documentaries from the last century, is a poignant example of this development. Aside from these topics, gender and …

Duoethnography As Transformative Praxis: Conversations About Nourishment And Coercion In The Covid-Era Academy, Natali Valdez, Megan Carney, Emily Yates-Doerr, Abril Saldaña-Tejeda, Jessica Hardin, Hanna Garth, Alyshia Galvez, Maggie Dickinson

Articles

This article introduces the feminist praxis of duoethnography as a way to examine the COVID era. As a group of diverse, junior, midcareer, and senior feminist scholars, we developed a methodology to critically reflect on our positions in our institutions and social worlds. As a method, duoethnography emphasizes the dialogical intimacy that can form through anthropological work. While autoethnography draws on individual daily lives to make sense of sociopolitical dynamics, duoethnography emphasizes the relational character of research across people and practices. Taking the relational aspects of knowledge production seriously, we conceptualized this praxis as a transformative method for facilitating radical …

Future Wireless Networking Experiments Escaping Simulations, Sachin Sharma, Saish Urumkar, Gianluca Fontanesi, Byrav Ramamurthy, Avishek Nag

Articles

In computer networking, simulations are widely used to test and analyse new protocols and ideas. Currently, there are a number of open real testbeds available to test the new protocols. In the EU, for example, there are Fed4Fire testbeds, while in the US, there are POWDER and COSMOS testbeds. Several other countries, including Japan, Brazil, India, and China, have also developed next-generation testbeds. Compared to simulations, these testbeds offer a more realistic way to test protocols and prototypes. In this paper, we examine some available wireless testbeds from the EU and the US, which are part of an open-call EU …

Articles

Based on case studies in Dublin, Ireland, this paper examines the motives for individuals to establish community gardens therein. The paper also outlines the capacities required for community groups to successfully establish and sustain community gardens in Ireland. These capacities include the involvement of individuals with a range of expertise, the presence of supportive community groups/organisations and state agencies, and access to resources, including land. The research findings, detailed in this paper, indicate that community gardens in urban settings encounter a number of challenges, including the absence of a mechanism for community groups to access land. The article provides a …

Limits Of Detection Of Mycotoxins By Laminar Flow Strips: A Review, Xinyi Zhao, Hugh Byrne, Christine M. O’Connor, James Curtin, Furong Tian

Articles

Mycotoxins are secondary metabolic products of fungi. They are poisonous, carcinogenic, and mutagenic in nature and pose a serious health threat to both humans and animals, causing severe illnesses and even death. Rapid, simple and low-cost methods of detection of mycotoxins are of immense importance and in great demand in the food and beverage industry, as well as in agriculture and environmental monitoring, and, for this purpose, lateral flow immunochromatographic strips (ICSTs) have been widely used in food safety and environmental monitoring. The literature to date describing the development of ICSTs for the detection of different types of mycotoxins using …

Pt Symmetry, Induced Mechanical Lasing, And Tunable Force Sensing In A Coupled-Mode Optically Levitated Nanoparticle, Sandeep Sharma, A. Kani, Mishkatul Bhattacharya

Articles

We theoretically investigate PT symmetry, induced mechanical lasing, and force sensing in an optically levitated nanoparticle with coupled oscillation modes. The coupling in the levitated system is created by the modulation of an asymmetric optical potential in the plane transverse to the beam trapping the nanoparticle. We show that such a coupling can lead to PT -symmetric mechanical behavior for experimentally realistic parameters. Further, by examining the phonon dynamics and the second-order coherence of the nanoparticle modes, we determine that induced mechanical lasing is also possible. Finally, we demonstrate that tunable ultrasensitive force sensing (∼zN/ √H z) can be engineered …

A Case Series Of Three Patients With Rare Pantalar Dislocation, Marissa Mogavero, Andrew Robitaille, Lawrence M. Fallat

Articles

Total talar dislocations are rare, significant surgical challenges for foot and ankle surgeons. These dislocations can be very difficult to manually close-reduce, requiring immediate surgical intervention secondary to arterial impingement, pain and risk of skin necrosis attributable to skin tenting. In this case series, we report on three patients who presented to the emergency room following a traumatic ankle injury. Ankle radiographs and computed tomography (CT) scans were obtained, revealing pantalar dislocations. Closed reduction utilizing Charnley’s principles was attempted in the emergency room through manual accentuation of the deformity, traction and reduction. Closed reduction was unsuccessful in all three patients …

Autonomous Vehicle Regulation & Trust: The Impact Of Failures To Comply With Standards, William H. Widen, Phillip Koopman

Articles

The autonomous vehicle (AV) industry works very hard to create public trust in both AV technology and its developers. Building trust is part of a strategy to permit the industry itself to manage the testing and deployment of AV technology without regulatory interference. This article explains how industry actions to promote trust (both individually and collectively) have created concerns rather than comfort with this emerging technology. The article suggests how the industry might change its current approach to law and regulation from an adversarial posture to a more cooperative one in which a space is created for government regulation consistent …

The Pledge Of Allegiance And Compelled Speech Revisited: Requiring Parental Consent, Caroline Mala Corbin

Articles

Since the Supreme Court decided West Virginia State Board of Education v. Barnette in 1943, free speech law has been clear: public schools may not force students to recite the Pledge of Allegiance. Nevertheless, in two states -Texas and Florida- students may decline to participate only with parental permission. The Eleventh Circuit Court of Appeals upheld the law on the grounds that the parental requirement furthered parents' substantive due process right to control the upbringing of their children.

The Eleventh Circuit decision is flawed both in its understanding of the First Amendment right to be free of compelled speech and …

A New Framework For Digital Taxation, Reuven Avi-Yonah, Young Ran (Christine) Kim, Karen Sam

Articles

The international tax regime has wide implications for business, trade, and the international political economy. Under current law, multinational enterprises do not pay their fair share of taxes to market countries where profits are generated because market countries are only allowed to tax companies with a physical presence there. Digital companies, like Google and Amazon, can operate entirely online, thereby avoiding market country taxes. Multinationals can also exploit existing tax rules by shifting their profits to low-tax jurisdictions, thereby avoiding taxes in the residence country where their headquarters are located.

Recently, a global tax deal was reached to tackle these …

Ai Insurance: How Liability Insurance Can Drive The Responsible Adoption Of Artificial Intelligence In Health Care, Ariel Dora Stern, Avi Goldfarb, Timo Minssen, W. Nicholson Price Ii

Articles

Despite enthusiasm about the potential to apply artificial intelligence (AI) to medicine and health care delivery, adoption remains tepid, even for the most compelling technologies. In this article, the authors focus on one set of challenges to AI adoption: those related to liability. Well-designed AI liability insurance can mitigate predictable liability risks and uncertainties in a way that is aligned with the interests of health care’s main stakeholders, including patients, physicians, and health care organization leadership. A market for AI insurance will encourage the use of high-quality AI, because insurers will be most keen to underwrite those products that are …

What Is Meaningful Participation For Physical Therapists In Multidisciplinary Cancer Conferences And Tumor Boards?, Stacy Weber, Athena A. Manzino, Christopher M. Wilson, Nicole D. Booms

Articles

Tumor boards are multidisciplinary team meetings composed of providers from different specialties who collaborate to provide comprehensive cancer care. Although the term “tumor board” may be used commonly in practice, these meetings are often referred to as multidisciplinary cancer conferences (MCCs) within the literature and are referred to as such in this article. At this time, there is no current literature describing the role of physical therapists (PTs) and rehabilitation professionals as part of the MCC or multidisciplinary tumor boards. Yet, PTs are often included as part of this multidisciplinary team in cancer care. This inclusion has not completely shifted …

Active Leisure And Ageing In Rural Ireland: Exploring Perceptions And Motivations To Facilitate And Promote Meaningful Physical Activity, Angie Hartnett, Catherine Gorman

Articles

The life expectancy of the world population is increasing and the art of aging well is of global interest (European Commission, n.d.). In Ireland, the number of people over the age of 60 will increase from 1.1 million currently, to 2.44 million by 2041, constituting nearly one third of its total population (Institute of Public Health, 2018). Despite the benefits of regular physical activity (pa), particularly with the frail (≥65 years and requiring a walking aid), rates of participation remain low (Colley et al., 2011). Health concerns raised, such as smoking and weight issues, are more prevalent in this cohort …
