IONIC LIQUID EXTRACTION UNVEILS PREVIOUSLY OCCLUDED HUMICBOUND IRON IN PEAT POREWATER

Extracellular iron reduction has been suggested as a candidate metabolic pathway that may explain a large proportion of carbon respiration in temperate peatlands. However, the o-phenanthroline colorimetric method commonly employed to quantitate iron and partition between redox species is known to be unreliable in the presence of humic and fulvic acids, both of which represent a considerable proportion of peatland dissolved organic matter. We propose ionic liquid extraction as a more accurate iron quantitation and redox speciation method in humic-rich peat porewater. We evaluated both o-phenanthroline and ionic liquid extraction in four distinct peatland systems spanning a gradient of physico-chemical conditions to compare total iron recovery and Fe2+:Fe3+ ratios determined by each method. Ionic liquid extraction was found to provide more accurate iron quantitation and speciation in the presence of dissolved organic matter. A multivariate approach utilizing fluorescence- and UV-Vis spectroscopy was used to identify dissolved organic matter characteristics in peat porewater that lead to poor performance of the o-phenanthroline method. Where these interferences are present, we offer an empirical correction factor for total iron quantitation by o-phenanthroline, as verified by ionic liquid extraction. The written work presented in this thesis is in preparation for submission to Soil Biology and Biochemisrty by T.J. Veverica, E.S. Kane, A.M. Marcarelli, and S.A. Green.

International flavours

It is an Olympic year and we have just witnessed the fantastic games hosted by Rio de Janeiro. Well done to team USA for winning the most medals overall but also well done to so many other nations and individuals who performed so well or were ambassadors in other ways. Teenage swimmer Yusra Mardini who swam for the refugee team and South Africa's Wayde van Niekerk who broke the longstanding 400 m record of Michael Johnson that has stood since 1999. Of course, we must mention sprinter Usain Bolt and swimmer Michael Phelps, who have now transcended superstar status and entered a new level of icon. My personal highlight was the sportsmanship witnessed in the 5000 m when American Abbey D’Agostino was accidentally felled by New Zealand runner Nikki Hamblin. D’Agostino helped Hamblin back to her feet but slumped to the track after realising her own injury. Hamblin helped her up and stayed with her so that both completed the race. The International Olympic Committee has awarded both with the prestigious Pierre de Coubertin award, also known as the International Fair Play Trophy. Fair play is of paramount importance in publishing in peer-reviewed papers. At CLAE we try and maintain, as do other journals, this by ensuring double blind peer review and allowing authors to select the most appropriate handling editor for their submission. Our handling editors are placed across the world (2 in Europe, 1 in the Americas, 1 in Australia and 1 in Asia) and part of their role is to encourage submissions from their region. Over the last decade we certainly have seen more and more papers from places that haven’t previously published in CLAE. In this issue of CLAE we have a true international blend of papers. We have papers from authors from the UK, USA, Iran, Jordan, France, Poland, Turkey, Nigeria, France, Spain and Brazil. I think it's a testament to the continued success of the journal that we are attracting new writers from so many parts of the world and retain papers from more established authors and research centres. We do continue to attract many weaker papers that are rejected early in the review process. Often these will be unexceptional case reports or papers describing a surgical technique. Case reports are published but only those that offer something original and especially those with interesting photographs. In this issue you will see Professor James Wolffsohn (UK) has an interesting paper around a lot of the focus of his recent research activity into clinical evaluation of methods of correcting presbyopia. In this paper he highlights predictors to aid success of presbyopic contact lenses. If you have been involved in any clinical work or research in the field of dry eye disease then you will know well the CLDEQ (Contact Lens Dry Eye Questionnaire) devised by Robin Chalmers and her colleagues (USA). This issue of CLAE details the latest research using the CLDEQ-8 (the 8 item version of the CLDEQ). The Shahroud Eye Cohort Study has produced many papers already and in this issue we see Fotouhi Akbar (Iran) looking at changes in central and peripheral corneal thickness over a five year period. These days we use a lot of new instrumentation, such as optical low-coherence reflectometry. In this issue Emre Güler (Turkey) compares that to a new optical biometry unit. Dry eye is more common and in this issue we see a study by Oluyemi Fasina (Nigeria) to investigate the disease in adults in South-West Nigeria. The TearLab™ is now commonly used to investigate osmolarity and Dorota Szczesna-Iskander (Poland) looks at measurement variability of this device. Following the theme of dry eyes and tear testing Renaud Laballe (France) looks at the use of scleral lenses as a reservoir-based ocular therapeutic system. In this issue we have a couple of papers looking at different aspects of keratoconus. Magdalena Popiela (UK) looks at demographics of older keratoconic patients in Wales, Faik Orucoglu (Turkey) reports a novel scoring system for distinguishing keratoconus from normal eyes, Gonzalo Carracedo (Spain) reports the effect of rigid gas permeable lens wear on dry eye in keratoconus and Hatice Nur Colak (Turkey) compares topographic and aberrations in keratoconus. Other interesting papers you will find are Mera Haddad (Jordan) investigates contact lens prescribing in Jordan, Camilla Fraga Amaral (Brazil) offers a report on the use of ocular prosthetics, Naveed Ahmed Khan (Malaysia) reports of the use of dimethyl sulfoxide in contact lens disinfectant and Michael Killpartrick (UK) offers a short piece with some useful advice on contamination risk factors that may occur from the posterior surface of disposable lenses. So for this issue I would say that the Gold Medal for biggest contribution in terms of papers has to go to Turkey. I could have awarded it to the UK too, but Turkey has three full papers and the UK has two plus one short communication. Turkey is also one of the countries that has shown the largest increase in submissions over the last decade. Finally, welcome aboard to our newest Editorial Board Member Nicole Carnt from Australia. Nicole has been an active researcher for many years and acted as a reviewer for CLAE many times in the past. We look forward to working with you.

Entre contestation et résignation : l’expérience de profilage racial de jeunes racisés ayant reçu des constats d’infraction dans le cadre du contrôle de l’occupation de l’espace public montréalais

Ce mémoire explore le vécu et la construction de l’expérience de jeunes racisés ayant reçu des constats d’infraction dans le cadre de leur occupation de l’espace public montréalais. Il s’agit spécifiquement d’appréhender, à partir de la sociologie de l’expérience de Dubet (1994), le profil et les conditions de vie, la présence dans l’espace public, les raisons et la nature des constats d’infraction, les stratégies mises en œuvre face au profilage racial ainsi que les conséquences du profilage racial sur les jeunes racisés. Se situant dans une perspective qualitative, la méthodologie de recherche a reposé sur le recueil de dix entrevues semi-dirigées, soit neuf jeunes hommes et une jeune fille entre 18 et 30 ans ayant eu des contacts avec la police dans le cadre du contrôle de l’espace public à Montréal. Basée essentiellement sur l’approche mixte de Miles et Huberman (2003), l’analyse du corpus a permis de rendre compte de l’hétérogénéité de l’expérience des jeunes racisés et profilés interrogés et de dégager deux types d’expérience de profilage racial : les contestataires et les résignés. Si les interactions avec les forces de l’ordre engendrent des traitements perçus comme discriminatoires, l’expérience se construit en fonction de la nature des interactions, du niveau de maturité et de la tranche d’âge des jeunes et elle se décline en une logique de soumission et une logique de lutte pour la contestation des constats d’infraction. Les résultats de la recherche démontrent par ailleurs la pertinence de l’accompagnement du jeune au niveau de la prise de conscience de ses droits et de la contestation des tickets reçus.

Into the Spotlight: Bringing Transparency, Consistency, and Efficiency to the Division of Appeals and Hearings

Currently, the Division of Appeals and Hearings of the South Carolina Department of Health and Human Services has no specific presence on the agency's website to provide information or to allow for the electronic submission of appeals. This project's focus was developing an online presence for the Division on SCDHHS' website. The page will make the Division's procedures publicly available to beneficiaries, providers, and agency program staff who attend hearings. Additionally, parties will have a secure online portal through which they can file appeals and upload supporting documentation, reducing the need to send appeals via first class mail. The online appeal portal will further the agency' s goal of reducing paper.

Terminology Cross-Domain Final Report

The InterPARES 2 Terminology Cross-Domain has created three terminological instruments in service to the project, and by extension, Archival Science. Over the course of the five-year project this Cross-Domain has collected words, definition, and phrases from extant documents, research tools, models, and direct researcher submission and discussion. From these raw materials, the Cross-Domain has identified a systematic and pragmatic way establishing a coherent view on the concepts involved in dynamic, experiential, and interactive records and systems in the arts, sciences, and e-government.The three terminological instruments are the Glossary, Dictionary, and Ontologies. The first of these is an authoritative list of terms and definitions that are core to our understanding of the evolving records creation, keeping, and preservation environments. The Dictionary is a tool used to facilitate interdisciplinary communication. It contains multiple definitions for terms, from multiple disciplines. By using this tool, researchers can see how Archival Science deploys terminology compared to Computer Science, Library and Information Science, or Arts, etc. The third terminological instrument, the Ontologies, identify explicit relationships between concepts of records. This is useful for communicating the nuances of Diplomatics in the dynamic, experiential, and interactive environment.All three of these instruments were drawn from a Register of terms gathered over the course of the project. This Register served as a holding place for terms, definitions, and phrases, and allowed researchers to discuss, comment on, and modify submissions. The Register and the terminological instruments were housed in the Terminology Database. The Database provides searching, display, and file downloads – making it easy to navigate through the terminological instruments.Terminology used in InterPARES 1 and the UBC Project was carried forward to this Database. In this sense, we are building on our past knowledge, and making it relevant to the contemporary environment.

Prevalencia y caracterización de la disfonía, en operadores de un call center en Bogotá Colombia.

Resumen Introducción: El uso de la voz profesional requiere de una técnica y medidas de conservación para no verse afectada. Un inadecuado esquema corporal en el profesional de la voz, ocasiona alteración en los parámetros respiratorios y vocales manifestándose como disfonía. Objetivo: Determinar la prevalencia y caracterización de disfonía en 200 tele operadores de un call Center en Bogotá Colombia. Métodos: Estudio de corte transversal con datos secundarios provenientes de una base de datos con registros de una población de 200 tele operadores de un call center en Bogotá, Colombia, a los cuales se les aplicó evaluación de respiración y de voz durante el año 2003. La estimación de la prevalencia de la disfonía se realizó a través de la distribución de frecuencias relativas. Se realizó caracterización de la población estudiada según variables sociodemográficas, ocupacionales y parámetros respiratorios y vocales a través de métodos estadísticos según la naturaleza de estas variables. Se determinó la asociación entre factores ambientales, síntomas asociados, síntomas vocales, perfil vocal de Wilson y disfonía mediante la prueba de Chi Cuadrado de Pearson. Resultados: la prevalencia de disfonía fue del 73% (n= 146), el 34% presentó grado de disfonía moderado. Los resultados obtenidos en los parámetros de evaluación vocal se encontraron dentro del rango de normalidad, analizados en forma individual (tono, rango intensidad) y se relacionan con los resultados obtenidos con la prevalencia disfonía. El 95,5% de los tele operadores los parámetros respiratorios se encontraron alterados. Los tele operadores con disfonía en comparación a los sin disfonía tuvieron mayor frecuencia de presentación de los siguientes factores ambientales: ruido (68% vs 50,9% p=0,03) y vapores (27,2% vs 11,3% p= 0,02), síntomas corporales y de la voz respectivamente: cuello (69,4% vs 54,7% p= 0,05), dolor en la laringe (19,7% vs 7,5% p= 0,04). Conclusión: La prevalencia de disfonía encontrada en este call center fue alta Lo que requiere la implementación de medidas de prevención como tamizajes acústicos, para hacer seguimiento a las cualidades de la voz más afectadas, entrenamiento respiratorio y vocal, pausas vocales y medidas de conservación de la voz, para contribuir a que el tele operador desarrolle un mejor manejo de sus cualidades vocales acorde con su uso y disminuir la prevalencia de disfonía.

El rol de las redes de apoyo transnacional en la evolución del régimen de trata de personas en la región del mekong, 2004-2015

Con el fin de la unipolaridad no sólo se fortalecieron mecanismos de gobernanza global como los Regímenes Internacionales, sino también se fortalecieron actores no estatales. A pesar de la importancia que tomaron estos dos elementos aún no existe una teoría que explique exhaustivamente la relación que existe entre ellos. Es por lo anterior que, la investigación busca responder de qué manera el rol de las Redes de Apoyo Transnacional ha incidido en la evolución del régimen de tráfico de personas en la Región del Mekong. Asimismo tiene como objetivo comprender las relación entre el Régimen y las Redes de Apoyo Transnacional a través de la formulación de un caso de estudio basado en metodologías cualitativas, específicamente, en el análisis teórico-constructivista y el análisis de contenido de documentos producidos por actores estatales y no estatales.

Exploration of polymetallic nodules in the Area: Reporting practices, data management and transparency

The International Seabed Authority (ISA) regulates the activities related with the exploration and exploitation of seabed mineral resources in the Area, which are considered as the "common heritage of mankind" under the United Nations Convention on the Law of the Sea.The ISA has also the mandate to ensure the protection of the marine environment.The development of good practices for the annual reporting and data submission by Contractors is crucial for the ISA to comply with the sustainable development of the mineral marine resources. In 2015,the ISA issued a new template for reporting on exploration activities, which includes the definition of the format for all geophysical, geological and environmental data to be collected and analysed during exploration. The availability of reliable data contributes to improve the assessment of the ISA on the activities in the Area while promoting transparency, which is considered as a major principle of industry bestpractices.

Improving understandability in consumer health information search: Uevora @ 2016 fire chis

This paper presents our work at 2016 FIRE CHIS. Given a CHIS query and a document associated with that query, the task is to classify the sentences in the document as relevant to the query or not; and further classify the relevant sentences to be supporting, neutral or opposing to the claim made in the query. In this paper, we present two different approaches to do the classification. With the first approach, we implement two models to satisfy the task. We first implement an information retrieval model to retrieve the sentences that are relevant to the query; and then we use supervised learning method to train a classification model to classify the relevant sentences into support, oppose or neutral. With the second approach, we only use machine learning techniques to learn a model and classify the sentences into four classes (relevant & support, relevant & neutral, relevant & oppose, irrelevant & neutral). Our submission for CHIS uses the first approach.

Constraint Programming-based Job Dispatching for Modern HPC Applications

A High-Performance Computing job dispatcher is a critical software that assigns the finite computing resources to submitted jobs. This resource assignment over time is known as the on-line job dispatching problem in HPC systems. The fact the problem is on-line means that solutions must be computed in real-time, and their required time cannot exceed some threshold to do not affect the normal system functioning. In addition, a job dispatcher must deal with a lot of uncertainty: submission times, the number of requested resources, and duration of jobs. Heuristic-based techniques have been broadly used in HPC systems, at the cost of achieving (sub-)optimal solutions in a short time. However, the scheduling and resource allocation components are separated, thus generates a decoupled decision that may cause a performance loss. Optimization-based techniques are less used for this problem, although they can significantly improve the performance of HPC systems at the expense of higher computation time. Nowadays, HPC systems are being used for modern applications, such as big data analytics and predictive model building, that employ, in general, many short jobs. However, this information is unknown at dispatching time, and job dispatchers need to process large numbers of them quickly while ensuring high Quality-of-Service (QoS) levels. Constraint Programming (CP) has been shown to be an effective approach to tackle job dispatching problems. However, state-of-the-art CP-based job dispatchers are unable to satisfy the challenges of on-line dispatching, such as generate dispatching decisions in a brief period and integrate current and past information of the housing system. Given the previous reasons, we propose CP-based dispatchers that are more suitable for HPC systems running modern applications, generating on-line dispatching decisions in a proper time and are able to make effective use of job duration predictions to improve QoS levels, especially for workloads dominated by short jobs.
