Compromiso organizacional y promedio escolar en estudiantes de maestría: el efecto moderador de las tendencias alocéntricas e idiocéntricas
Authors: Cernas Ortiz Daniel Arturo , Nava Rogel Rosa María
Published: September 2019

El objetivo de este trabajo fue examinar la relación del compromiso organizacional con el promedio escolar en estudiantes de la Maestría en Administración de la Universidad Autónoma del Estado de México. También se analizó si las tendencias alocéntricas e idiocéntricas de los alumnos moderan esta relación. Se aplicó una encuesta en la universidad mencionada (n = 80). Los resultados indican que el compromiso organizacional y el promedio escolar tienen una relación negativa que se amplifica cuando las tendencias alocéntricas son altas y que se reduce cuando las altas son las tendencias idiocéntricas. En general, el compromiso organizacional es deseable para las organizaciones pero podría tener efectos perniciosos en las calificaciones de las personas que estudian y trabajan.
LA CRIMINALIZACIÓN DEL COLECTIVO INMIGRANTE EN EL DISCURSO DE LA PRENSA
Authors: Rodríguez Pedro Garrido
Published: September 2019

El discurso de la prensa con respecto a las migraciones suele caracterizarse por la simplificación, la reproducción de estereotipos, la visión parcial y la ambigüedad. En el presente artículo se emplean las metodologías de análisis de contenido y análisis crítico del discurso para estudiar el discurso de la prensa en lo referente al colectivo inmigrante. Se percibe cómo, al reflejo del discurso político, a la vez que existe un enfoque proactivo con las migraciones, minoritario, existe un robusto y creciente enfoque reactivo que, haciendo uso de sutiles herramientas lingüísticas, traslada una imagen sobredimensionada, negativa y con frecuencia criminalizadora del colectivo inmigrante. Asimismo, se detallan las principales directrices y ejemplos de buenas prácticas al efecto.

Published: September 2019

O presente artigo visa analisar o comportamento da jurisprudência do Tribunal de Justiça do Estado do Rio Grande do Sul, nos últimos cinco anos, no que tange à motivação quanto à autoria e à materialidade para remessa dos homicídios praticados na condução de veículo automotor, mediante dolo eventual, ao Conselho de Sentença (decisão de pronúncia). Busca-se, assim, verificar, a partir da análise de recursos em sentido estrito (principal instrumento para revisão da sentença de pronúncia), quais são os critérios adotados pelo respectivo Tribunal para o envio do julgado ao Tribunal Popular. Para construção do objeto de indagação será utilizado como recurso metodológico a pesquisa quali-quantitativa efetuada com base nos julgados encontrados, com exposição de gráficos e tabelas comparativas, somando-se com uma técnica de pesquisa, exploratória e bibliográfica. Ao fim, a pesquisa aponta como conclusão a extrema dificuldade de se identificar o elemento subjetivo do acusado, nos casos de homicídio no trânsito e, por conta disso, a jurisprudência do egrégio TJRS tem submetido as hipóteses de dolo eventual ao Conselho de Sentença, em razão de que cabe a este a análise probatória dos autos.

Published: September 2019

Este texto tem como objetivo problematizar mobilizações matemáticas no contexto da Educação de Jovens e Adultos. Trata-se de um recorte da pesquisa de mestrado intitulada “Alice no país das práticas docentes que mobilizam matemática no contexto da Educação de Jovens e Adultos: vozes de personagens”, que tem como objetivo analisar práticas docentes no ensino de matemática no contexto da Educação de Jovens e Adultos com vistas à evidenciar indicadores para uma proposta de formação pedagógica contínua que valorize a relação da matemática do cotidiano com a escolar, junto ao corpo docente da EJA. A pesquisa de abordagem qualitativa e com proposta intervencionista, aconteceu em três encontros pedagógicos com quinze professores que ensinam matemática. As vozes ecoadas nos encontros foram problematizadas à luz da orientação filosófica baseada na terapia desconstrutivista do filósofo Wittgenstein e nos estudos de Antonio Miguel por meio de jogos narrativos de linguagem. Foi oportunizado aos professores a possibilidade de compartilharem suas práticas no ensino de matemática na EJA. Os professores reconhecem que os alunos da EJA possuem conhecimentos matemáticos, e confirmam as dificuldades encontradas no que se refere à matemática escolar. Quanto a relação entre as matemáticas do cotidiano e escolar, buscam contextualizar as atividades escolares com a realidade dos alunos. Apesar dos esforços, compartilham a angústia pelo insucesso escolar de grande parte dos alunos, entendendo como necessária a formação continuada no ensino de matemática. Nessa perspectiva, faz-se necessário pensar as aulas de matemática como ambiente de trocas.

The Ulch language: current state and research prospects
Authors: Gorbunova V. A.
Published: September 2019

The paper discusses the current linguistic situation of the Ulchs, a minor ethnic group occupying a small area in the Far East region of the Russian Federation. After several decades of gradual decline, the indigenous Ulch language has reached the point of near extinction. The presented statistical data shows that the number of native speakers has decreased dramatically since the beginning of the 21st century (from 732 down to 154 countrywide). The author suggests several factors that contributed heavily to the erosion of the language. The primary one is the lack of a written form up until late 20th century, which both stunted its development as a communication tool and hindered the process of passing down cultural knowledge and linguistic skills. Failing to cover a required range of registers, the Ulch language was eventually relegated to the language of informal social interactions, typically among family members, with Russian performing the rest of linguistic functions. As the government and community groups are growing aware of the Ulch linguistic situation and engaging in efforts to make the indigenous language more prominent, reversing the shift is still possible. Including Ulch into the curriculums of junior and middle schools has allowed the younger generation to achieve a certain degree of oral competence. Social activities are being organized for adult speakers to encourage the use of language in a wider range of contexts. However, the process of language documentation, essential for revitalization, is revealed to still be in the beginning stages. The author presents an overview of all linguistic studies dedicated to the Ulch language and concludes that only a general framework of the system has been traced. Until mid-twentieth century the researchers mostly focused on collecting and processing the language material, offering only standalone observations related to the linguistic features. T.I. Petrova and later O.P. Sunik provided more detailed accounts of the Ulch phonetics, grammar and lexis, but both works only present a broad strokes description of the language that can’t be considered comprehensive. Creating a full record of the Ulch grammar, vocabulary and syntax appears to be the primary task that needs to be undertaken in order to make the recovery a more likely outcome.

Published: September 2019

All-solid-state batteries are often expected to replace conventional lithium-ion batteries in the future. However, the practical electrochemical and cycling stability of the best-conducting solid electrolytes, i.e. lithium thiophosphates, are still critical issues that prevent long-term stable high-energy cells. In this study, we use stepwisecyclic voltammetry to obtain information on the practical oxidative stability limit of Li10GeP2S12, a Li2S‑P2S5glass, as well as the argyrodite Li6PS5Cl solid electrolytes. We employ indium metal and carbon black as the counter and working electrode, respectively, the latter to increase the interfacial contact area to the electrolyte as compared to the commonly used planar steel electrodes. Using a stepwise increase in the reversal potentials, the onset potential at 25 °C of oxidative decomposition at the electrode-electrolyte interface is identified. X‑ray photoelectron spectroscopy is used to investigate the oxidation of sulfur(-II) in the thiophosphate polyanions to sulfur(0) as the dominant redox process in all electrolytes tested. Our results suggest that after the formation of these decomposition products, significant redox behavior is observed. This explains previously reported redox activity of thiophosphate solid electrolytes, which contributes to the overall cell performance in solid-state batteries. The stepwise cyclic voltammetryapproach presented here shows that the practical oxidative stability at 25 °C of thiophosphate solid electrolytes against carbon is kinetically higher than predicted by thermodynamic calculations. The method serves as an efficient guideline for the determination of practical, kinetic stability limits of solid electrolytes.

Given the need for modern researchers to produce open, reproducible scientific output, the lack of standards and best practices for sharing data and workflows used to produce and analyze molecular dynamics (MD) simulations have become an important issue in the field. There are now multiple well-established packages to perform molecular dynamics simulations, often highly tuned for exploiting specific classes of hardware, and each with strong communities surrounding them, but with very limited interoperability/transferability options. Thus, the choice of the software package often dictates the workflow for both simulation production and analysis. The level of detail in documenting the workflows and analysis code varies greatly in published work, hindering reproducibility of the reported results and the ability for other researchers to build on these studies. An increasing number of researchers are motivated to make their data available, but many challenges remain in order to effectively share and reuse simulation data. To discuss these and other issues related to best practices in the field in general, we organized a workshop in November 2018 ( https://bioexcel.eu/events/workshop-on-sharing-data-from-molecular-simulations/). Here, we present a brief overview of this workshop and topics discussed. We hope this effort will spark further conversation in the MD community to pave the way towards more open, interoperable and reproducible outputs coming from research studies using MD simulations.

Renewable harvesting clean and hydrogen energy using the benefits of novel multicatalytic materials of high entropy alloy (HEA equimolar Cu-Ag-Au-Pt-Pd) from formic acid with minimum energy input has been achieved in the present investigation. The synthesis effect of pristine elements in the HEA drives the electro-oxidation reaction towards non-carbonaceous pathway . The atomistic simulation based on DFT rationalize the distinct lowering of the d-band center for the individual atoms in the HEA as compared to the pristine counterparts. This catalytic activity of the HEA has also been extended to methanol electro-oxidation to show the unique capability of the novel catalyst. The nanostructured HEA, properties using a combination of casting and cry omilling techniques can further be utilized as fuel cell anode in direct formic acid/methanol fuel cells (DFFE).

Towards Autonomous Machine Learning in Chemistry via Evolutionary Algorithms
Authors: Vishwakarma Gaurav , Haghighatlari Mojtaba , Hachmann Johannes
Published: September 2019

Machine learning has been emerging as a promising tool in the chemical and materials domain. In this paper, we introduce a framework to automatically perform rational model selection and hyperparameter optimization that are important concerns for the efficient and successful use of machine learning, but have so far largely remained unexplored by this community. The framework features four variations of genetic algorithm and is implemented in the chemml program package. Its performance is benchmarked against popularly used algorithms and packages in the data science community and the results show that our implementation outperforms these methods both in terms of time and accuracy. The effectiveness of our implementation is further demonstrated via a scenario involving multi-objective optimization for model selection.
Towards an Artificial Carbohydrates Supply on Earth
Authors: Dinger Florian , Platt Ulrich
Published: September 2019

How to feed a growing global population in a secure and sustainable way? The conventional, biogenic agriculture has yet failed to provide a reliable concept which circumvents its severe environmental externalities—such as the massive use of land area, water for irrigation, fertiliser, pesticides, herbicides, and fossil fuel. In contrast, the artificial synthesis of carbohydrates from atmospheric carbon dioxide, water, and renewable energy would allow not only for a highly reliable production without those 10 externalities, but would also allow to increase the agricultural capacities of our planet by several orders of magnitude. All required technology is either commercially available or at least developed on a lab-scale. No directed research has, however, yet been conducted to wards an industry-scale carbohydrate synthesis because the biogenic carbohydrate production was economically more competitive. Taking the environmental and socioeconomic externalities of the conventional sugar production into account, this economical narrative has to be questioned. We estimate the production costs of artificial sugar at 1 C/kg. While the today’s spot market price for conventional sugar is about 0.3 C/kg, we estimate its total costs (including external costs) at 0.9 C/kg in humid regions and 2 C/kg in semi-arid regions. Accordingly, artificial sugar appears already today to be the less expensive way of production. The artificial sugar production allows in principle also for a subsequent synthesis of other carbohydrates such as starch and cellulose as well as fats. This manuscript aims at rising research interest and at enhancing awareness for a transition to a nonagricultural and more resource conserving way to supply carbohydrates for food.

Ao abrir essa fenda na escola, o projeto Mulheres Inspiradoras inseriu esses estudantes como sujeitos diante de suas histórias, as quais penetraram os portões da escola sob a roupagem de currículos vivos e legitimados por uma prática pedagógica transgressora.
USAGE OF HIGH-QUALITY ENGINE OILS WITH EXTENDED REPLACEMENT INTERVALS: FEATURES OF THE EQUIPMENT OPERATION
Authors: Machekhin N. Y. , Shirlin I. I. , Pashukevich S. V.
Published: September 2019

Introduction. The effective operation of cars largely depends on the state of the engines, their downtime in maintenance and repair. Since the maintenance of modern engines is often reduced to the replacement of engine oil, the increase in the duration of its work significantly reduces maintenance costs and downtime in maintenance. Long maintenance-free operation of the internal combustion engines of automotive vehicles is directly related to the state of the engine oil used in this power unit. The aim of the paper is to show the features of the equipment operation with significant intervals of the engine oils’ replacement in order to increase the efficiency of its usage. The paper presents data on the features of the equipment operation when using high-quality motor oils with extended replacement intervals.

Materials and methods. The authors conducted performance tests on the basis of MercedesBenzAxor, MercedesBenzActros cars. The manufacturer provided an estimate of the performance of engine oils. The main performance characteristics of motor oils were assessed using standard methods: kinematic viscosity was measured using a Stabinger viscosimeter, the base number was determined by an automatic AT-500 titrator, the content of wear products was obtained using an ASP-coupled emission spectrophotometer.

Results. As a result, the authors presented data on the dependence of the changes in the main indicators of engine oil performance while the operating time and also substantiated the requirements for the volumes of fresh engine oil to compensate losses.

Discussion and conclusions. The intermediate control allows detecting faults in the internal car engines, as well as providing the most accurate prediction of the resource of the lubricant under consideration. Therefore, the increasing of the engine oil change interval allows getting a significant economic effect.
INFLUENCE OF THE SCOPE ADDITION ON THE STRUCTURE FORMATION OF THE CEMENT STONE BY THE METHOD OF QUANTITATIVE X-RAY PHASE ANALYSIS

Published: September 2019

Introduction. The processes of structure formation of cement compositions and the development of effective technologies of building materials is an urgent task for building material science. The use of large-scale man-made product of pulp and paper enterprises – osprey as a fibrous filler in organic and mineral compositions is the successful decision of the problem. The paper analyzes the ways of using osprey in the building materials’ production. The aim of the research is to study the osprey influence on the processes of structure formation of cement stone by quantitative x-ray phase analysis.

Materials and methods. The organic and mineral compositions were obtained on the basis of portland cement and osprey. The authors studied the compositions’ phase of osprey, portland cement and the processes of cement stone structure formation in organ and mineral compositions by quantitative x-ray phase analysis.

Results. The authors determined the compositions’ phase of mineral impurities of osprey, cellulose, cement, cement stone, organic and mineral compositions and two compositions containing 25 and 75% by weight.

Discussion and conclusions. The osprey application as a filler in the organic and mineral composition causes inhibition of processes of cement hydration. The presence of osprey in the hardening organic and mineral composition leads to a change in the composition and structure of the cement stone in comparison with the phase composition of the cement stone without additives. The result of these changes is a significant increase in the amount of calcite, waterite and a significant decrease in the amount of portland. The authors establish that the effective joint work of the reinforcing component of the osprey with the cement matrix is possible with a limited amount of osprey in organic and mineral compositions.

The present investigation attempted to evaluate the existence and survival of spoilage
microorganisms in four common sea fishes (Poma, Rupchanda, Koral and Tuna) available
in Bangladesh and to determine the effects of cooking temperature to optimize the growth
of fish microflora. Moreover, the status of fish in frozen condition after cooking was also
studied. A total 4 categories of sea fishes were collected from the local shops in Dhaka
city. Raw, cooked and frozen fish samples were analyzed for the existence of pathogenic
bacteria through the conventional cultural techniques and the confirmative biochemical
identification procedures. Total viable bacteria were present in all four fish samples in
raw, cooked and frozen condition up to 6 log CFU/mL. Most of the raw fish samples were
found to harbor a huge population of microorganisms up to 5 log CFU/mL including the
fecal coliforms. Several specific bacterial species like E. coli, Klebsiella spp., Salmonella
spp., Shigella spp., Staphylococcus spp., Pseudomonas spp. and Vibrio spp. were present
in raw samples. However, the microbial load reduced from the fish after cooking and the
status was static in frozen condition. Thus, the incidence of fecal coliforms in raw fish
may be considered as a serious threat to the public health upon consumption of such
fishes.
