XANES spectroscopy of sulfides stable under reducing conditions
Authors: Anzures Brendan A. , Parman Stephen W. , Milliken Ralph E. , Lanzirotti Antonio , Newville Matthew
Published: December 2019

X-ray absorption near-edge structure (XANES) spectroscopy is a powerful technique to quantitatively investigate sulfur speciation in geologically complex materials such as minerals, glasses, soils, organic compounds, industrial slags, and extraterrestrial materials. This technique allows non-destructive investigation of the coordination chemistry and oxidation state of sulfur species ranging from sulfide (2–oxidation state) to sulfate (6+ oxidation state). Each sulfur species has a unique spectral shape with a characteristic K-edge representing the s → p and d hybridization photoelectron transitions. As such, sulfur speciation is used to measure the oxidation state of samples by comparing the overall XANES spectra to that of reference compounds. Although many S XANES spectral standards exist for terrestrial applications under oxidized conditions, new sulfide standards are needed to investigate reduced (oxygen fugacity, fO2, below IW) silicate systems relevant for studies of extraterrestrial materials and systems. Sulfides found in certain meteorites (e.g., enstatite chondrites and aubrites) and predicted to exist on Mercury, such as CaS (oldhamite), MgS (niningerite), and FeCr2S4 (daubréelite), are stable at fO2 below IW-3 but rapidly oxidize to sulfate and/or produce sulfurous gases under terrestrial surface conditions. XANES spectra of these compounds collected to date have been of variable quality, possibly due to the unstable nature of certain sulfides under typical (e.g., oxidizing) laboratory conditions. A new set of compounds was prepared for this study and their XANES spectra are analyzed for comparison with potential extraterrestrial analogs. S K-edge XANES spectra were collected at Argonne National Lab for FeS (troilite), MnS (alabandite), CaS (oldhamite), MgS (niningerite), Ni1–xS, NiS2, CaSO4 (anhydrite), MgSO4, FeSO4, Fe2(SO4)3, FeCr2S4 (daubréelite), Na2S, Al2S3, Ni7S6, and Ni3S2; the latter five were analyzed for the first time using XANES. These standards expand upon the existing S XANES end-member libraries at a higher spectral resolution (0.25 eV steps) near the S K-edge. Processed spectra, those that have been normalized and “flattened,” are compared to quantify uncertainties due to data processing methods. Future investigations that require well-characterized sulfide standards, such as the ones presented here, may have important implications for understanding sulfur speciation in reduced silicate glasses and minerals with applications for the early Earth, Moon, Mercury, and enstatite chondrites.

Authors: Jollands Michael C. , Zhukova Irina , O'Neill Hugh St.C. , Hermann Jörg
Published: December 2019

26Mg tracer diffusion coefficients were determined in single crystals of pure synthetic forsterite (Mg2SiO4). Isotopically enriched powder sources both acted as the 26Mg source and buffered the activities of silica (aSiO2) at forsterite + protoenstatite (Mg2Si2O6) (high aSiO2) and forsterite + periclase (MgO) (low aSiO2). Experiments were conducted at atmospheric pressure between 1250 and 1600 °C, and at oxygen fugacities (fO2s) between 10–12 bars (CO-CO2 mix) and 10–0.7 bars (air). The resulting diffusion profiles were measured along the three principal crystallographic axes (a, b, and c; ||[100], ||[010], ||[001]) using laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS), with a quadrupole mass spectrometer. These measurements were corroborated by ion microprobe using the sensitive high resolution ion microprobe-reverse geometry (SHRIMP-RG) instrument.

Mg tracer diffusion is anisotropic, with D[001] > D[010] > D[100], the difference in diffusion coefficients varying by about one order of magnitude at a given temperature with crystallographic orientation. Diffusion is faster in protoenstatite-buffered than periclase-buffered conditions, again with around one order of magnitude difference in diffusivity between buffering conditions. There is no apparent effect of fO2 on diffusion. A global fit to all data, including data from Chakraborty et al. (1994) and Morioka (1981) yields the relationship:

log 10 D = log 10 D 0 ( m 2 s - 1 ) + 0 . 61 ( ± 0 . 03 ) log 10 a SiO 2 + - 359 ( ± 10 ) kJ / mol 2 . 303 R T

where log10D0 is –3.15 (±0.08), –3.61 (±0.02), and –4.01 (± 0.05) m2 s–1 for the [001], [010], and [100] directions, respectively (1 s.d.). The LA-ICP-MS technique reproduces diffusion coefficients determined by SHRIMP-RG, albeit with slightly different absolute values of isotope ratios. This shows that LA-ICPMS, which is both accessible and rapid, is a robust analytical method for such tracer diffusion studies.
Computer Adaptive Testing Simulations in R
Authors: ERDEM KARA Basak
Published: December 2019

Computer adaptive testing is an important research field in educational
measurement, and simulation studies play a critically important role in CAT
development and evaluation. Both Monte Carlo and Post Hoc simulations are
frequently used in CAT studies in order to investigate the effects of different
factors on test efficiency and to compare different test designs. Although
there are several softwares for CAT simulations, R is preferred since it
includes many free packages and gives researchers opportunity to write their
own functions according to their own requirements besides being free. The
purpose of this study is to make an introduction and demonstration of how to
use catR package in CAT simulations. Different examples were provided in the
context of this study and R codes were presented with explanations. Then, the
output files were briefly explained. It is thought that this paper is helpful
for the researchers who are interested in CAT simulations.

Authors: Deineko Liudmyla , Tsyplitska Olena , Deineko Oleksandr
Published: December 2019

The paper aims to highlight the status of the circular economy implementation in the EU and Ukraine, as well as to determine the advantages, challenges, opportunities and barriers to transition to circular supply chains. The main problems of waste management in Ukraine are explored, including faulty legislation, underinvestment, state policies and enlightenment regarding the circular economy, formal approach to the implementation of programs and strategies that should improve economic conditions, dominance of most waste-generative – extractive – industries in the economic structure of Ukraine. It is found out that the legislative framework for circular- and bio-economics in Ukraine does not meet the global challenges and requirements of the Association Agreement between Ukraine and the EU and needs urgent improvement measures. Studying the EU experience allowed describing the advantages and challenges of a circular economy that emerge in Ukraine. The article presents a mathematical model aimed at describing the peculiarities of a circular economy in the countries with low and high levels of industrial ecologization as well as understanding conditions for resource conservation during production processes. An econometrical model of the correlation between the solid waste generation, GDP and capital investment into environmental protection in Ukraine is used to demonstrate the absence of the latter’s influence on the waste generation at the current technological level of the national industries. The research results allow developing recommendations for state policy for the industrial sector and environmental protection that may be implemented at the current stage to achieve Sustainable Development Goals 2030.

Alveolar Type 2 Epithelial Cells as Potential Therapeutics for Acute Lung Injury/Acute Respiratory Distress Syndrome
Authors: Zhang Honglei , Cui Yong , Zhou Zhiyu , Ding Yan , Nie Hongguang
Published: December 2019

:

Acute lung injury/acute respiratory distress syndrome is a common clinical illness with high morbidity
and mortality, which is still one of the medical problems urgently needed to be solved. Alveolar type 2 epithelial
cells are an important component of lung epithelial cells and as a kind of stem cells, they can proliferate and
differentiate into alveolar type 1 epithelial cells, thus contributing to lung epithelial repairment. In addition, they
synthesize and secrete all components of the surfactant that regulates alveolar surface tension in the lungs.
Moreover, alveolar type 2 epithelial cells play an active role in enhancing alveolar fluid clearance and reducing
lung inflammation. In recent years, as more advanced approaches appear in the field of stem and progenitor cells
in the lung, many preclinical studies have shown that the cell therapy of alveolar type 2 epithelial cells has great
potential effects for acute lung injury/acute respiratory distress syndrome. We reviewed the recent progress on the
mechanisms of alveolar type 2 epithelial cells involved in the damaged lung repairment, aiming to explore the
possible therapeutic targets in acute lung injury/acute respiratory distress syndrome.

Authors: Fueger Christopher , Sergio Lauren E , Heuer Sabine , Petrovska Labina , Huddleston Wendy E
Published: December 2019

Aim: We examined the long-term effects of concussions in young adult females on visuomotor behavior during a visually-guided reaching task of various complexities. Materials & methods: 20 females with a history of longer than 6 months since a concussion and 20 healthy females quickly and accurately performed a delayed reach to a previously cued target. Results: As both cognitive and motor load increased, task performance decreased for both groups (p < 0.05). However, contrary to our primary hypothesis, no differences in task performance were found between the two experimental groups (p > 0.05). Conclusion: The young adult females with a remote history of concussion demonstrated no deficits in visuomotor behavior on an attention-mediated reaching task as compared with control participants.

Published: December 2019

4-hydroxyl-2-nonenal (HNE) is a lipid oxidation product that can increase oxymyoglobin oxidation. However, limited research has evaluated the role of oxygen partial pressure in HNE-induced metmyoglobin formation. Therefore, the objective of was to compare the effects of atmospheric and high-oxygen partial pressure on HNE-induced oxymyoglobin oxidation in vitro. Oxymyoglobin was incubated with or without HNE at atmospheric (20% O2) or high-oxygen (80% O2) partial pressure. Metmyoglobin formation was measured after 0, 48, and 96 h of incubation at 4°C, and mass spectrometry was utilized to characterize the covalent binding of HNE to myoglobin. High-oxygen condition (80% O2) increased (P < 0.05) HNE-induced oxymyoglobin oxidation compared with the atmospheric partial pressure condition (20% O2). However, HNE was bound to myoglobin at both high-oxygen and atmospheric partial pressure conditions, with no differences (P > 0.05) in the extent of adduct formation. These results suggest that high-oxygen conditions had no effect on extent of HNE-binding, but can increase oxymyoglobin oxidation.

Cognición situada y racionalidad. Hacia una ecología interactiva del razonamiento
Authors: Fonseca Patrón Ana Laura
Published: December 2019

La racionalidad ecológica que propone el grupo de investigación ABC destaca en su proyecto normativo la relación entre las heurísticas rápidas y frugales y el ambiente; por ello, considera que se trata de una racionalidad situada. El primer objetivo de este trabajo es mostrar que, si bien la racionalidad ecológica puede entenderse como una forma de situar la racionalidad, ello no implica situar el razonamiento. En particular, se muestra que la manera de entender la ecología del razonamiento es estática, como en los estudios estándar de la cognición. El segundo objetivo es mostrar que es deseable y viable caracterizar el razonamiento heurístico de manera que nos permita entender cómo las interacciones con el entorno son parte de las estructuras cognitivas que sustentan nuestras capacidades de razonamiento, es decir, formular una ecología interactiva del razonamiento.
Scientific and technical support of survey, design, and construction as a mandatory element of attaining the required project objectives
Authors: Lapidus Azariy A.
Published: December 2019

Introduction. Scientific and technical support (STS) of survey (STSS), design (STSD), and construction (STSC) in accordance with regulatory documents and standards must be executed at facilities belonging to the KS-3 Class and characterizing by an enhanced level of responsibility. However, currently, there is no clear understanding of the necessary and sufficient volume of work accomplished in the course of the STS as well as of the skill level of companies carrying out the work. Materials and methods. Existing regulatory documents regarding the STS were analysed. A system approach was suggested for forming the initial data array. The approach is based on the decomposition of the erection process of industrial and civil buildings. Specific conditions for the scientific and technical support of survey, design, and construction were considered. Results. Existing regulatory documents regarding the STS of survey, design, and construction does not permit the unambiguous formation of the necessary and sufficient support program. In connection with this, the main steps to be accomplished for the creation of an STS system were formulated. Such an approach will allow all the participants of the construction process to understand the STS requirements and volume unambiguously, avoiding various subjective opinions. The main guidelines of the STS accomplishment were identified. Such types of construction activity as new material or equipment creation, on which recommendations are given for the STS accomplishment, are presented. Conclusions. A roadmap of six top-priority steps is suggested. Its realization in the closest time would allow accomplishing the facility STS on terms unified for all the STS participants.
Morphological Variations of Robusta Coffee As a Response to Different Altitude in Lampung
Authors: Prastowo Erwin , Arimarsetiowati Rina
Published: December 2019

The coffee growth is considered to depend, partly, on the environmental condition at which they develop to accomplish both vegetative and generative stages. An exploratory survey in Lampung aimed at investigating the morphological characteristics of 13 Robusta coffee accessions growing on different altitudes.Local superior coffee clones were selected from eight farms, and subjected to identifications. Three key issues were concerned for both quantitatively, i.e. plant components of leaves, branches, and fruits, and qualitatively such as leaves and fruit characteristics, i.e. colour and shape. The analysis shows a similarity of about 60% of total qualitative variable identified among different accessions. The remaining characters are suggested to be more varying such as flush colour, leaf surface, ripe fruit colour, and stipule shape. Furthermore, a quantitative analysis showed a higher level of similarity for fruit characters, i.e. fruit length, -width, and -thickness, and to a slightly lower level for leaf characteristics, i.e. leaf length and -width, and number of productive branches. It was revealed that some variables, i.e. fruit weight; leaf and seed; and canopy characteristics, explaining the morphological variation of coffee throughout the accessions. Furthermore, cluster analysis may indicated a possible similarity of coffee morphologies either from area with different or the same environmental conditions. A high heterogeneity related to environmental conditions, genotypic variations, plant nutritional status, and agronomic practices, which unable to confirm in the present study, may limit the specific conclusions.
Study on Relationship Between Age and Coffee Preference: Application to Specialty Coffee Association Brewing Control Chart
Authors: Xue Joy
Published: December 2019

The Specialty Coffee Association Brewing Control chart has been used for the past 50 years, and is intended to assist the coffee brewer by stating the brew ratio and TDS (total dissolved solids) value needed to brew an “ideal” cup of coffee. Since coffee is a common and popular beverage that is consumed among populations ranging from children to elders, the objective of this study was to find out whether taste preferences in coffee vary based on age and whether these preferences match the current brewing control chart standard. Data collected in this study was based on a taste test with 32 total participants selected randomly. Of these participants, 10 fell into the 10-19 years old age range, 5 in the 20-29 range, 4 in the 30-39 range, 7 in the 40-49 range, and 6 in the 50-59 range. Based on the data from these respondents, no obvious trend between age range and coffee preference was observed; but, this is subject to change with larger sample sizes.Overall taste preferences, however, do generally fit the current standard ideal range on the coffee brewing control chart.

Authors: Wagner Matthias , Gurr Gwendolin , Siemon Miriam
Published: December 2019

When it comes to complex topics in the field of health and risk communication, experts are of high importance for the credibility of a news media report. This paper examines the use of experts and their roles in the news media coverage of multi-resistant pathogens by means of a quantitative content analysis of German print and online news. A cluster analysis of the expert statements identifies three different statement frames describing different expert roles. The results show manifest patterns of selected expert sources, which points to professionalized mechanisms of selecting expert sources for news media reports.
Emerging Global Cities: Structural Similarities and Historical Differences
Authors: Portes Alejandro , Martínez Brandon
Published: December 2019

The evolution of the capitalist economy over the centuries has been characterized by the rise of one or a few cities to a position of prominence as centers for coordination of financial commercial activities worldwide. Sassen identified three such “global cities” in the contemporary era: London, New York, and Tokyo. We trace the emergence of those such “new global” cities—Dubai, Miami, and Singapore—highlighting the structural similarities of their economies and their rather different historical trajectories. Politics and a legal system anchored in English Common Law are elements found in all three cities, but in very different forms and with different functions. We examine the political evolution of each of these cities and the challenges facing them in the short-to-medium term. The experiences of these three cities offer key lessons for those aspiring to a similar position of global prominence in the future.
Ocio ético: afrontando la alienación y la deshumanización en los hospitales
Authors: Bermúdez Rey M. Teresa , Alonso Domínguez Ángel , Arnaiz García Andrea
Published: December 2019

El artículo estudia la necesidad de ocupar el tiempo libre de los pacientes en los hospitales, y si estas prácticas de animación hospitalaria son percibidas por ellos como un medio para mejorar su calidad de vida. Para alcanzar los objetivos, se lleva a cabo una exploración cualitativa, con recogida de información individualizada, siguiendo un protocolo preestablecido de preguntas cerradas. Con esta metodología se pretende delimitar, de forma objetiva, el tiempo dedicado a las diferentes actividades de ocio en el hospital. Los resultados obtenidos permiten establecer correlaciones entre las respuestas de los pacientes y las variables analizadas.
Empotrado (embedded) en trincheras mediáticas
Authors: Gil Calvo Enrique
Published: December 2019

El texto describe y analiza, en primera persona, y a modo de testimonio, la trayectoria del autor como colaborador de prensa en medios informativos, a través de los cuales llegó a ser uno de los sociólogos con mayor proyección pública durante tres décadas. La reflexión incluye una comparación de esa actividad con la ejercida por los corresponsales de guerra que informan sobre conflictos armados, cuyo último avatar es estar “empotrados” (embedded) en unidades combatientes para asumir su visión de la contienda.
Retos de la divulgación feminista sobre la desigualdad de género en España
Authors: Guilló Guirard Clara Inés
Published: December 2019

Tras un prolongado periodo de despolitización, la revitalización del feminismo ha favorecido el debate sobre las situaciones de discriminación que afectan a las mujeres por razones de género. La “desigualdad” es una preocupación característica de la Sociología; no obstante, existe una importante distancia conceptual y de medios para tratar los intereses de las mujeres y sus preocupaciones dentro de la disciplina. El texto plantea tres retos. Los dos primeros están en relación a la visibilidad de las temáticas de género: el reconocimiento del androcentrismo, y la posición que ocupa en las corrientes principales de la Sociología. El tercer reto es el relativo a la representación de datos mixtos en un contexto tecnológico complejo. La perspectiva de género requiere aunar el análisis descriptivo con causas sociohistóricas y consecuencias concretas para los sujetos. Implica gestionar un volumen considerable de datos mixtos; generalmente desde una perspectiva evolutiva y comparativa. Además, requiere conceptos específicos para situar a la audiencia en el enfoque feminista. Por ello exponemos las ventajas de la infografía como la estrategia principal para la divulgación de las aportaciones feministas.
Amparo Serrano-Pascual y Maria Jepsen (Eds.) The Deconstruction of Employment as a Political Question: “Employment” as a Floating Signifier
Authors: Fernández Rodríguez Carlos J.
Published: December 2019

El estatus del empleo ha cambiado de forma muy significativa en las últimas décadas. Si durante el periodo posterior a la Segunda Guerra Mundial, los conocidos como “treinta años gloriosos”, el empleo se constituyó como un elemento central para la integración de la ciudadanía —en un modelo basado en la redistribución económica, la extensión de los derechos sociales y la institucionalización del Estado del Bienestar—, desde la década de los ochenta la influencia del neoliberalismo ha deteriorado significativamente su papel en la sociedad.
Wikipédia e museus: uma parceria possível?
Authors: Monteiro Juliana
Published: December 2019

A Wikipédia é, hoje, considerada uma das principais fontes terciárias de informação da atualidade, tendo grande impacto na difusão de conteúdos relacionados a todas as áreas do conhecimento humano. Outro aspecto importante da Wikipedia é o modo como ela é gerenciada: por uma comunidade ativa de editores e editoras voluntários, que constroem ferramentas, regras e colaboram para melhorar ou criar artigos. Nesse sentido, muitos museus têm procurado trabalhar com a Wikipédia e seus projetos irmãos como parte de uma estratégia digital para disseminar o conhecimento que produzem. As possibilidades derivadas de tal conexão entre instituições culturais e Wikipedia são numerosas, desde a reutilização criativa de imagens e outros conteúdos digitais relacionados às coleções, até a produção de novos dados, com o apoio dos editores da enciclopédia, sobre a coleções. É, portanto, uma forma aberta, colaborativa e inovadora de criar novos contextos para o patrimônio cultural. Sendo assim, é válido discutir quais os impactos que parcerias entre museus e a Wikipédia podem ter para a forma como as instituições museológicas se portam diante do ciclo de produção de conhecimento. Esse é um dos objetivos do presente artigo.

Digital health technology, especially digital and health applications (“apps”), have been developing rapidly to help people manage their diabetes. Numerous health-related apps provided on smartphones and other wireless devices are available to support people with diabetes who need to adopt either lifestyle interventions or medication adjustments in response to glucose-monitoring data. However, regulations and guidelines have not caught up with the burgeoning field to standardize how mobile health apps are reviewed and monitored for patient safety and clinical validity. The available evidence on the safety and effectiveness of mobile health apps, especially for diabetes, remains limited. The European Association for the Study of Diabetes (EASD) and the American Diabetes Association (ADA) have therefore conducted a joint review of the current landscape of available diabetes digital health technology (only stand-alone diabetes apps, as opposed to those that are integral to a regulated medical device, such as insulin pumps, continuous glucose monitoring systems, and automated insulin delivery systems) and practices of regulatory authorities and organizations. We found that, across the U.S. and Europe, mobile apps intended to manage health and wellness are largely unregulated unless they meet the definition of medical devices for therapeutic and/or diagnostic purposes. International organizations, including the International Medical Device Regulators Forum and the World Health Organization, have made strides in classifying different types of digital health technology and integrating digital health technology into the field of medical devices. As the diabetes digital health field continues to develop and become more fully integrated into everyday life, we wish to ensure that it is based on the best evidence for safety and efficacy. As a result, we bring to light several issues that the diabetes community, including regulatory authorities, policy makers, professional organizations, researchers, people with diabetes, and health care professionals, needs to address to ensure that diabetes health technology can meet its full potential. These issues range from inadequate evidence on app accuracy and clinical validity to lack of training provision, poor interoperability and standardization, and insufficient data security. We conclude with a series of recommended actions to resolve some of these shortcomings.
