An Examination Of Students' Perceptions Of The Kekulé Resonance Representation Using A Perceptual Learning Theory Lens, Thomas Kim, Leslie Kate Wright, Kathryn Miller

Articles

Students in chemistry often demonstrate difficulty with the principle of resonance. Despite many attempts to mitigate this difficulty, there have been few attempts to examine the root cause of these issues. In this study, students were assessed for their perception of Kekulé structures based on perceptual learning theory, which is grounded in cognitive mechanisms of visual perception. The data from this assessment shows that students are perceiving inappropriate clues from this representation, which infers that the image itself might be an impediment to learning about resonance. Employment of a metarepresentational competence approach was used to address these misperceptions.

The Americans With Disabilities Act: Legal And Practical Applications In Child Protection Proceedings, Joshua B. Kay

Articles

Parents with disabilities, particularly those with intellectual disability and/or mental illness, are disproportionately represented in the child protection system.1 Once involved in the system, they are far more likely than parents without disabilities to have their children removed and their parental rights terminated. The reasons for this are many. Parents with disabilities are relatively likely to experience other challenges that are themselves risk factors for child protection involvement. In addition, child protection agencies, attorneys, courts, and related professionals often lack knowledge and harbor biases about parents with disabilities, increasing the likelihood of more intrusive involvement in the family. Yet research …

Temperature-Compensated Magnetic Field Sensing With A Dual-Ring Structure Consisting Of Microfiber Coupler-Sagnac Loop And Fiber Bragg Grating - Assisted Resonant Cavity, Fangfang Wei, Dejun Liu, Arun Kumar Mallik, Gerald Farrell, Qiang Wu, Gang-Ding Peng, Yuliya Semenova

Articles

A novel temperature-compensated magnetic field sensor based on a ring erbium-doped fiber laser combined with a fiber Bragg grating (FBG) and a Sagnac loop containing a microfiber coupler (MFC) and magnetic fluid is proposed and investigated. Thanks to the dual-ring structure of the MFC-Sagnac loop and the FBG-assisted resonant cavity, the output of the structure has two distinct laser peaks. In addition to the magnetic field sensing capability, the proposed structure can simultaneously provide temperature information. The maximum experimentally demonstrated sensitivity to a magnetic field determined from the spectral shift of one laser peak is 102 pm/mT in the magnetic …

Available Food Options At Local Shops In Relation To Food Insecurity Among Older Adults In Sharpeville, South Africa, Sanjoy Saha, Brenda Abu, Wilna Oldewage-Theron, Abdul Egal

Articles

Due to limited resources and complex food access systems in urban areas, especially older adults are more vulnerable to poor dietary intake and food insecurity in low-income areas in South Africa. This study assessed the prevalence of food insecurity among the older adults and explored the availability of healthy foods in local shops. It was a crosssectional study conducted in an eldercare centre in Sharpeville, South Africa with an estimated representative sample of 88 participants. Validated tools were used to measure the socio-economic, dietary diversity intake (24-hour dietary recall), household food security and access from the participants. Listing of available …

Artificial Intelligence In The Medical System: Four Roles For Potential Transformation, W. Nicholson Price Ii

Articles

Artificial intelligence (AI) looks to transform the practice of medicine. As academics and policymakers alike turn to legal questions, including how to ensure high-quality performance by medical AI, a threshold issue involves what role AI will play in the larger medical system. This Article argues that AI can play at least four distinct roles in the medical system, each potentially transformative: pushing the frontiers of medical knowledge to increase the limits of medical performance, democratizing medical expertise by making specialist skills more available to non-specialists, automating drudgery within the medical system, and allocating scarce medical resources. Each role raises its …

Automatic Acquisition Of Annotated Training Corpora For Test-Code Generation, Magdalena Kacmajor, John D. Kelleher

Articles

Open software repositories make large amounts of source code publicly available. Potentially, this source code could be used as training data to develop new, machine learning-based programming tools. For many applications, however, raw code scraped from online repositories does not constitute an adequate training dataset. Building on the recent and rapid improvements in machine translation (MT), one possibly very interesting application is code generation from natural language descriptions. One of the bottlenecks in developing these MT-inspired systems is the acquisition of parallel text-code corpora required for training code-generative models. This paper addresses the problem of automatically synthetizing parallel text-code corpora …

Single Photon Transfer Using Levitated Cavityless Optomechanics, Pardeep Kumar, Mishkatul Bhattacharya

Articles

We theoretically explore a quantum memory using a single nanoparticle levitated in an optical dipole trap and subjected to feedback cooling. This protocol is realized by storing and retrieving a single-photon quantum state from a mechanical mode in levitated cavityless optomechanics. We describe the effectiveness of the photon-phonon-photon transfer in terms of the fidelity, the Wigner function, and the zero-delay secondorder autocorrelation function. For experimentally accessible parameters, our numerical results indicate robust conversion of the quantum states of the input signal photon to those of the retrieved photon. We also show that high fidelity single-photon wavelength conversion is possible in …

Surveying The Scene: How Representatives’ Views Informed A New Era In Irish Workplace Dispute Resolution, Brian Barry

Articles

The Workplace Relations Act 2015 introduced a major overhaul of workplace dispute resolution bodies in Ireland, streamlining a complicated system for resolving workplace disputes comprising multiple fora into a two-tier structure. The article describes and analyses the results of two surveys undertaken by the author of the views of employment law and industrial relations practitioners and other representatives in Ireland before the reforms in 2011 and after the reforms in 2016. This article describes the purpose, methodology and considers the results of both surveys. The 2011 survey informed the agenda for reforming the Irish workplace dispute resolution system in 2015. …

Good Sentences, Patrick Barry

Articles

To write good sentences, you need to read good sentences. Skilled writers and editors know this, so they seek out good sentences wherever they can find them—the short stories of Alice Munro, the political essays of William F. Buckley, even well-crafted cartoons, speeches, and advertisements. They read not just with voracity but also with an eye toward larceny, always on the lookout for moves that they can learn and repurpose.

Reckless Juveniles, Kimberly Thomas

Articles

Modern doctrine and scholarship largely take it for granted that offenders should be criminally punished for reckless acts.1 Yet, developments in our understanding of human behavior can shed light on how we define and attribute criminal liability, or at least force us to grapple with the categories that have existed for so long. This Article examines recklessness and related doctrines in light of the shifts in understanding of adolescent behavior and its biological roots, to see what insights we might attain, or what challenges these understandings pose to this foundational mens rea doctrine. Over the past decade, the U.S. Supreme …

Blockchain-Based Token Sales, Initial Coin Offerings, And The Democratization Of Public Capital Markets, Jonathan Rohr, Aaron Wright

Articles

Best known for their role in the creation of cryptocurrencies like bitcoin, blockchains are revolutionizing the way technology entrepreneurs finance their business enterprises. In 2017 alone, tech entrepreneurs raised over $6 billion through the sale of blockchain-based digital tokens, with some sales lasting mere seconds before selling out. In a token sale, also referred to as an “initial coin offering” or “ICO,” organizers of a project sell digital tokens to members of the public to finance the development of new technological platforms and services. After the initial sale, cryptocurrency exchanges scattered across the globe list tokens for trading and facilitate …

A Close-Up Look At Pcr, Callie J. Donahue, Ashley A. Adair, Leslie Kate Wright, Dina Newman

Articles

The Polymerase Chain Reaction (PCR) is a fundamental laboratory technique that allows for the amplification of many copies of a desired DNA target sequence. Despite its prevalence, undergraduate students often have poor comprehension about the underlying molecular mechanisms of PCR and the components necessary to carry out the reaction. We designed an interactive modeling activity to help students visualize the underlying molecular processes of denaturation, annealing, and extension, and to see how PCR parallels in vivo DNA replication. During the activity, students mimic denaturation, annealing, and extension by synthesizing DNA strands from individual nucleotides and primers in the 5’ to …

The Critical Juncture Concept’S Evolving Capacity To Explain Policy Change, John Hogan

Articles

This article examines the evolution of our understanding of the critical junctures concept. The concept finds its origins in historical intuitionalism, being employed in the context of path dependence to account for sudden and jarring institutional or policy changes. We argue that the concept and the literature surrounding it—now incorporating ideas, discourse, and agency—have gradually become more comprehensive and nuanced as historical institutionalism was followed by ideational historical institutionalism and constructivist and discursive institutionalism. The prime position of contingency has been supplanted by the role of ideas and agency in explaining critical junctures and other instances of less than transformative …

A Framework For Evaluating Model-Driven Self-Adaptive Software Systems, Basel Magableh

Articles

In the last few years, Model Driven Development (MDD), Component-based Software Development (CBSD), and context-oriented software have become interesting alternatives for the design and construction of self-adaptive software systems. In general, the ultimate goal of these technologies is to be able to reduce development costs and effort, while improving the modularity, flexibility, adaptability, and reliability of software systems. An analysis of these technologies shows them all to include the principle of the separation of concerns, and their further integration is a key factor to obtaining high-quality and self-adaptable software systems. Each technology identifies different concerns and deals with them separately …

Transferability: Helping Students And Attorneys Apply What They Already Know To New Situations (Part 1), Edward R. Becker

Articles

Every fall, I work with my first year law students to begin developing their legal writing skills. They work hard learning how to analyze cases objectively, predict how a court might resolve a dispute, and convey their assessments to an experienced attorney. Their improvement from September to December is noticeable. They have only one semester of law school behind them and still have much to learn, but they’re on their way…In the second semester, we begin focusing on advocacy. The first assignment asks students to draft a pretrial brief. When I review the drafts, I’m struck by how many problems …

Context Oriented Software Middleware, Basel Magableh

Articles

This article proposes a new paradigm for building an adaptive middleware that supports software systems with self-adaptability and dependability. In this article, we wish to explore how far we can support the engineering of self- adaptive applications using a generic and platform-independent middleware architecture provided by non-specialised programming languages such as Context-Oriented Programming (COP), and Aspect-Oriented Programming (AOP), and not limited to a specific platform or framework. This gives the software developers the flexibility to construct a self-adaptive application using a generic and reusable middleware components that employ popular design patterns, instead of forcing the software developers to use a …

The Impact Of Social Inclusion On The Social Development Of Students With A General Learning Difficulty In Postprimary Education In Ireland, Barry Ryan, Niall King

Articles

Over the past decade, there has been a societal push for social inclusion in Ireland for students with special educational needs (SEN). As a result, the number of dedicated special needs schools has dramatically decreased across the country as students with SEN enrol, instead, in mainstream schools. Dedicated SEN schools provided an environment in which students with a general learning difficulty (GLD) could develop at a pace suited to them. However, this developmental pace is different for GLD students in a mainstream school. This research explores the social development of students with a GLD in a mainstream school in postprimary …

Systems In Play: Simon Nicholson's Design 12 Course, University Of California, Berkeley, 1966, Tim Stott

Articles

In 1966, British artist, designer and educator Simon Nicholson (1934–1990) offered a lower division course, Design 12, at the College of Environmental Design, UC Berkeley. Controversially, Nicholson promoted play as the principal method of design and invited children to assess students’ projects on the Berkeley campus and in local schools, parks, playgrounds and hospitals. This article presents Design 12 as an important example of environmental design pedagogy in the USA, which uniquely attempted to synthesize British post-war constructivism with ‘design science’ and adventure play. The result was a course that placed play at the centre of design pedagogy, where it …

A New Era For Reuse Social Enterprises In Ireland? The Capacities Required For Achieving Sustainability, Gerard Doyle

Articles

The conventional linear relationship between production and consumption is no longer sustainable. A key component of the transition towards a more sustainable society is the continuation in use of products for longer and the development of a repair and reuse culture. Reuse social enterprises contribute to addressing a range of environmental, economic and social issues facing urban areas. This paper is concerned with, firstly, the motivations for citizens to establish reuse social enterprises in Ireland. Secondly, the paper examines the factors that contribute to reuse social enterprises in Ireland becoming sustainable.

The research points to the necessity of reuse social …

Philanthropy-Supported Journalism, Harry Browne

Articles

There is a widespread perception that the market is failing to ensure the provision of high quality, impactful journalism, especially investigative work and in‐depth coverage of governmental and international affairs. One answer to that market failing has been the development of philanthropy‐supported journalism. Some writers see this as a potentially important, if partial, solution to journalism's problems, strengthening the editorial focus on creating social and policy impacts. Others have expressed concern that philanthropic support draws journalists toward elite orientations, with both funders themselves and their desired audiences representing the socioeconomic upper tiers.

The Effects Of Mixed Membership In A Deliberative Forum: The Irish Constitutional Convention Of 2012–2014, David Farrell, Jane Suiter, Clodagh Harris, Kevin Cunningham

Articles

The Constitutional Convention was established by the Irish government in 2012. It was tasked with making recommendations on a number of constitutional reform proposals. As a mini-public, its membership was a mix of 66 citizens (randomly selected) and 33 politicians (self-selected). Its recommendations were debated on the floor of the Irish parliament with three of them leading to constitutional referendums; other recommendations are in the process of being implemented. This article uses data gathered during and after the operation of the Convention to examine this real-world example of a mixed-membership mini-public. The focus is on how the inclusion of politicians …

You’Re Fired! Why The Alj Multi-Track Dual Removal Provisions Violate The Constitution & How To Fix Them, Linda D. Jellum

Articles

This Article explains why the for-cause removal provisions for ALJs are unconstitutional and offers three potential solutions to remedy this problem. Part I provides background information, which explains that the APA was a compromise of competing interests. Some wanted ALJs to be completely in-dependent from their agencies to further unbiased decision-making and inde-pendence, and others feared agencies would lose control over setting policy, should ALJs have such an independent function.Ultimately, Congress com-promised by including provisions to make the ALJs more independent, while also ensuring that agencies retained complete control to set policy.

As part of the independence piece of the …
