A study of the anodic oxidation of acetylene on gold electrodes

The object of this investigation was to establish a mechanism for the anodic oxidation of acetylene on gold electrodes in aqueous solutions. It is known that anodic oxidation of organic compounds on gold electrodes produces a large number of organic intermediates and end products. Therefore, it appeared worthwhile to establish a mechanism that could provide a better understanding of the fuel cell electrode kinetics and possibly lead to new methods of organic syntheses --Introduction, page 2

BEYOND CLINICAL GUIDELINES: HOW CARE PATHWAYS AND QUALITY-IMPROVEMENT METHODS CAN SUPPORT BETTER ALLERGY CARE

The increasing prevalence of allergic disease has resulted in the recognition of allergy as a global public health concern. Yet health services worldwide appear to be ill-equipped to deliver high-quality allergy care. Clinical guidelines have been developed to describe what high-quality care looks like for most allergic diseases. However, allergy guidelines do not describe how the delivery of such care is organised across clinicians and provider organisations with varying degrees of access to allergy expertise and clinical resources. In this article, we describe how care pathways can be used to improve the organisation and delivery of allergy care in accordance with the characteristics of allergic disease and local constraints in the health service. We then describe how quality-improvement methods can support the successful realisation of allergy care pathways in practice. Realising care pathways involves a highly complex process of changing the way care is practised and organised. This could involve developing a new service, clinical training or other interventions. Qualityimprovement methods were developed as a guide to navigate and support the process of change and improvement

Extracting Implicitly Asserted Propositions in Argumentation

Argumentation accommodates various rhetorical devices, such as questions, reported speech, and imperatives. These rhetorical tools usually assert argumentatively relevant propositions rather implicitly, so understanding their true meaning is key to understanding certain arguments properly. However, most argument mining systems and computational linguistics research have paid little attention to implicitly asserted propositions in argumentation. In this paper, we examine a wide range of computational methods for extracting propositions that are implicitly asserted in questions, reported speech, and imperatives in argumentation. By evaluating the models on a corpus of 2016 U.S. presidential debates and online commentary, we demonstrate the effectiveness and limitations of the computational models. Our study may inform future research on argument mining and the semantics of these rhetorical devices in argumentation.Comment: EMNLP 202

(3+1)-Dimensional Schwinger Terms and Non-commutative Geometry

We discuss 2-cocycles of the Lie algebra \Map(M^3;\g) of smooth, compactly supported maps on 3-dimensional manifolds $M^3$ with values in a compact, semi-simple Lie algebra \g. We show by explicit calculation that the Mickelsson-Faddeev-Shatashvili cocycle \f{\ii}{24\pi^2}\int\trac{A\ccr{\dd X}{\dd Y}} is cohomologous to the one obtained from the cocycle given by Mickelsson and Rajeev for an abstract Lie algebra \gz of Hilbert space operators modeled on a Schatten class in which \Map(M^3;\g) can be naturally embedded. This completes a rigorous field theory derivation of the former cocycle as Schwinger term in the anomalous Gauss' law commutators in chiral QCD(3+1) in an operator framework. The calculation also makes explicit a direct relation of Connes' non-commutative geometry to (3+1)-dimensional gauge theory and motivates a novel calculus generalizing integration of \g-valued forms on 3-dimensional manifolds to the non-commutative case.Comment: 13 page

Reconceptualising Preservice Teachers’ Subject Knowledge in Climate Change and Sustainability Education: A Framework for Initial Teacher Education from England, UK

Climate Change and Sustainability Education (CCSE) has been gaining prominence with the imminent climate emergency humanity is facing. This paper draws upon a conceptual framework created to support the development of preservice teachers’ subject knowledge of CCSE whilst undertaking Initial Teacher Education (ITE) programs in England. The core aims and learning outcomes within the framework, namely knowledge; attitudes, values and behaviours; and competences and capabilities, are defined to illustrate what subject knowledge looks like, in this area, for preservice teachers in England. This paper highlights data gathered from 71 preservice teachers via an initial presurvey from three ITE institutions across England. The data were gathered from Early Years and Primary and Secondary phase trainees across both postgraduate and undergraduate programmes. The presurvey captured a range of qualitative and quantitative responses from preservice teachers to showcase priority areas, from their perspective, in the teaching of CCSE. The responses were coded and then themed according to the three aims and learning outcomes of the framework (knowledge; attitudes, values and behaviours; and competences and capabilities) to understand preservice teachers’ views on CCSE at the start of their courses. The findings suggest that preservice teachers lack key subject knowledge in CCSE to teach it effectively in schools. Hence, this paper recommends further work needs to be carried out to embed CCSE work in ITE courses across England. It is further suggested that the CCSE framework highlighted in this paper can act as a key national document to support ITE institutions to conceptualise the teaching and learning of CCSE across their ITE programmes

2013 Study on Children of Seriously Wounded Service Members

Over the course of one year, researchers from The Caster Family Center for Nonprofit and Philanthropic at the University of San Diego interviewed a total of 125 participants, including seriously wounded service members, their spouses and children, as well as military, civilian and nonprofit professionals who work with this population. The study included two phases to ensure a comprehensive understanding around the population and its unfulfilled needs: The first phase focused on understanding the specific needs of children of seriously wounded service members through interviews, focus groups, and reviews of existing research; the second phase focused on an assessment of government and nonprofit programs available to identify gaps that exist.https://digital.sandiego.edu/npi-military/1003/thumbnail.jp
