Covid PDS Plus: An E-PDS & Healthcare Platform Towards Pandemic Restoration
Authors: Shrivastava Vedant
Published: December 2020

During the COVID-19 crisis, millions of migrants daily-wage workers and homeless people around the world are facing food insecurity. This has forced migrants to travel to their hometowns during the pandemic thereby exposing them to greater health risks and also accelerating the risk of spread of virus. Anecdotal evidence demonstrates the importance of enforcing food security and distribution policies to tide the crisis. However, the effects of these policies on containing mobility during the crisis remain unknown. This paper presents a prototype of technology enabled e-PDS (pubic distribution system) and healthcare platform to connect different stakeholders i.e. people, government, NGOs.
Eficiencia cuantitativa de la función docente en la universidad: ingeniería química como caso de estudio
Authors: López P. Arcesio
Published: December 2020

Del seguimiento académico de seis diferentes grupos de estudiantes admitidos durante los años 1972, 1973 y 1974, se observa un reducido número de egresados, una alta tasa de retiros forzosos y voluntarios, y una importante proporción de ellos que aún se encuentran como alumnos regulares de la Facultad. Lo anterior apunta a una baja en la eficiencia cuantitativa de la carrera que puede ser sintomático de un fenómeno generalizado en la Universidad.
Ein holistischer Design-Based Research-Modellentwurf für die Hochschuldidaktik
Authors: Reinmann Gabi
Published: December 2020

Der Beitrag beschreibt und begründet ein holistisvches DBR-Modell für die Hochschuldidaktik, das in fünf Schritten entfaltet wird: Ich bestimme in einem ersten Schritt fünf semantische Felder, welche den Bedeutungsumfang eines DBR-Zyklus abstecken. Ich bezeichne diese bewusst nicht als Phasen oder Prozesse, weil es hier primär um die Bedeutungen des Handelns in DBR geht, die das Wesen von DBR als Ganzes prägen. In einem zweiten Schritt definiere ich darauf aufbauend fünf Handlungsfelder, in die sich Aktivitätsschwerpunkte projizieren lassen. Der Begriff des Handlungsfelds soll verdeutlichen, dass es hier um konkrete Aktivitäten geht, die immer nur ein Teil vom Ganzen sein können, weil jedes Handeln eine gewisse Fokussierung der Aufmerksamkeit braucht. Ich schlage in einem dritten Schritt Spielfelder vor: Diese metaphorisch bezeichnete Brücke zwischen dem Handlungsfokus (als Teil) und dem Wesenskern (als Ganzem) von DBR eignet sich dazu, die vor allem Experten sich eröffnenden Handlungsspielräume zu beleuchten. Diese drei Schritte bilden zusammen den Argumentationsgang für die Beschreibung und Begründung des holistischen DBR-Modellentwurfs. In einem vierten Schritt gehe ich auf die Methodenfrage in DBR ein und prüfe, inwiefern das Modell dazu geeignet ist, typische Schwierigkeiten im Umgang mit Methoden in DBR konstruktiv aufzufangen. Die Rolle von Design-Gegenständen in DBR greife ich in einem fünften und letzten Schritt auf und gehe wiederum der Frage nach, welchen Mehrwert das holistische Modell hierfür haben kann. Der Beitrag endet mit einem zusammenfasenden Fazit.
Produções científicas em cursos de pós-graduação sobre o rompimento da barragem de fundão: perspectivas para o campo educacional
Authors: Oliveira Bárbara , Ferreira Carla Jatoba
Published: December 2020

O colapso da Barragem de Fundão, no dia 5 de novembro de 2015, foi o maior desastre socioambiental brasileiro e grande parte dos debates sobre o ocorrido se converteram em um conjunto de produções acadêmicas nos programas de pós-graduação em todo o país. Assim, com o objetivo de compreender essas produções, mapeamos os estudos produzidos nas diferentes áreas do conhecimento sobre o desastre e elaboramos o estado do conhecimento das teses e dissertações depositadas até o ano de 2019. Nesse contexto, evidenciamos o espaço assumido pelo campo educacional nessas produções acadêmicas. A escassez de alguns estudos indicam o foco da preocupação sobre o desastre e demonstra que a discussão é quase totalmente silenciada no campo educacional. Portanto, faz-se necessário fortalecer o campo de estudos acerca dos desastres, bem como pensar estrategicamente sobre como o campo educacional pode contribuir com o debate.

Dentre os problemas mencionados pelos profissionais estão aspectos relacionados à cultura local, ao receio da revelação forçada do diagnóstico de HIV positivo a terceiros, à ausência de uma adequada compreensão sobre os benefícios do tratamento, à forma de organização dos serviços de saúde, a questões de gênero, a aspectos sociais como fome, dificuldades financeiras e problemas com transporte, dentre outros.
O Psíquico e o Corporal da Sexualidade nas Origens da Psicanálise freudiana
Authors: Celes Luiz Augusto M. , Lindenmeyer Cristina
Published: December 2020

Resumo O artigo tem por objetivo explorar, em uma perspectiva teórica conceitual, a presença corporal da sexualidade na compreensão da psicanálise, não se esgotando ela no psiquismo. Argumenta-se que as vivências primitivas da sexualidade (a sexualidade infantil) não somente determinam formas da fantasia e dos sintomas, mas vigem como vivências corporais de estímulo e excitação, satisfação, prazer de órgão e dor. Para isso, percorre-se os diversos modos da presença da sexualidade nas neuroses e nas perversões, tais como compreendidas a partir dos primeiros textos de Freud, mostrando suas raízes no corpo e seus traços originários como permanentemente corporais. Conclui-se com a irredutibilidade entre psiquismo, sexualidade e corpo.
¿Imputación penal por el ámbito de organización de terceros?: el caso chileno de la responsabilidad penal de las personas jurídicas
Authors: Palominos Gonzalo García
Published: December 2020

Resumen El artículo tiene por objetivo problematizar el elemento más discutido del sistema de responsabilidad penal de personas jurídicas chileno: la exigencia de que el delito de la persona física sea «consecuencia» del incumplimiento, por parte de la persona jurídica, de los deberes de dirección y supervisión. El artículo propone, como modo de superación de la posible incompatibilidad con el principio de autodeterminación que rige la responsabilidad penal personal, desarrollar criterios de imputación diferenciados y complementarios que permitan sostener la coexistencia de la responsabilidad de la persona física y jurídica. La propuesta final rechaza la analogía «conductual» en la reconstrucción del ilícito de la persona jurídica e invita a orientar la dogmática hacia la generación de «procesos» como manifestación en la realidad social de la «voluntad» de la organización; en este marco, propone el «dominio de la organización sobre el proceso» como principal factor de generación de responsabilidad.
Medidor prismático hexagonal: uma alternativa à macromedição
Authors: Siqueira Natally Annunciato , Souza Podalyro Amaral de
Published: December 2020

RESUMO A medição de vazão é fundamental para a gestão de processos que envolvem fluidos. Em empresas de saneamento, contabilizar as entradas e saídas de água é essencial para gerir faturamentos e perdas, podendo ser mensurada por meio de variados instrumentos com diferentes princípios de aplicação. Dados os altos custos de aquisição dos macromedidores usuais, bem como as dificuldades de instalação e manutenção, a macromedição no Brasil é deficiente. O tubo Pitot Cole é um medidor capaz de determinar a vazão em tubulações pelo diferencial de pressão. Suas principais vantagens são o baixo custo e a fácil instalação, que pode ocorrer com a tubulação em carga. Em contrapartida, suas peças são frágeis e de formato complexo. Este trabalho propõe a construção de um medidor de vazão simples e robusto com tomadas de pressão instaladas em faces opostas de um prisma hexagonal e avalia a viabilidade na mediação de vazão. Os resultados mostraram-se promissores dadas a estabilidade e a forte correlação linear obtidas no coeficiente de calibração.

Published: December 2020

RESUMO O conhecimento das populações bacterianas responsáveis pela biodegradação dos resíduos sólidos dispostos em aterros sanitários pode levar ao desenvolvimento de alternativas tecnológicas viáveis para o tratamento e a estabilização dos resíduos, resultando em impactos positivos para a operação de aterros, a recuperação de energia, a saúde pública e o meio ambiente. O objetivo deste trabalho foi caracterizar a diversidade bacteriana associada à biodegradação de resíduos sólidos urbanos (RSU) aterrados em uma célula experimental no município de Campina Grande, Paraíba. O estudo abrangeu as etapas de construção, planejamento estatístico dos bairros de Campina Grande para coleta e preenchimento da célula experimental com RSU. As amostras de DNA das bactérias encontradas nos RSU foram extraídas com o Kit Power Soil DNA Isolation. Em seguida, foi realizada a análise genética com primers universais para bactérias via reação em cadeia da polimerase (PCR) e eletroforese em gel de gradiente com desnaturante (DGGE), e, por fim, sequenciamento genético (região 16S do RNAr). Após o exame microbiológico, as principais bactérias associadas aos táxons foram: Uncultured Pseudomonas sp, Uncultured bacterium, Enterobacter sp., Klebsiella pneumoniae e Uncultured Bacillus sp., sugerindo que nos RSU existem representantes ainda desconhecidos e/ou não isolados que estão relacionados aos processos de hidrólise, acidogênese e acetogênese na digestão anaeróbia dos resíduos.
Effects of coal ash supplementation on aerobic granular sludge cultivated in a simultaneous fill/draw sequencing batch reactor

Published: December 2020

ABSTRACT This study aimed to verify if coal ash, a residue from thermal power plants, could act as a granulation nucleus, cations source, and abrasive element to favor granules formation and stability in aerobic granular sludge (AGS) systems. Two simultaneous fill/draw sequencing batch reactors (SBRs) (R1 and R2) were operated with 6-h cycles, i.e., the filling and drawing phases occurred simultaneously, followed by the reaction and settling phases. R1 was maintained as control, while R2 was supplemented with coal ash (1 g·L-1) on the first day of operation. Granulation was achieved in both reactors, and no significant differences were observed in terms of settleability, biomass retention, morphology, resistance to shear, and composition of the EPS matrix. However, the ash addition did not change the settleability, biomass retention, granule morphology, shear resistance, and extracellular polymeric substances (EPS) content significantly. COD removal was high (≥ 90%), while nitrogen (~50%) and phosphorus (~40%) removals were low, possibly due to the presence of nitrate during the anaerobic phase. With granulation, microbial population profile was altered, mainly at the genus level. In general, the operational conditions had a more considerable influence over granulation than the ash addition. The possible reasons are because the ash supplementation was performed in a single step, the low sedimentation rate of this particular residue, and the weak interaction between the ash and the EPS formed in the granular sludge. These factors appear to have decreased or prevented the action of the ash as granulation nucleus, source of cations, and abrasive element.
U.S. International Transactions in 1995

The current account deficit was counterbalanced by large recorded net capital inflows and a large positive statistical discrepancy.
Recent Changes in U.S. Family Finances: Results from the 1998 Survey of Consumer Finances
Authors: Kennickell Arthur B. , Starr-McCluer Martha , Surette Brian J.
Published: December 2020

Using data from the Federal Reserve Board's two most recent Surveys of Consumer Finances, this article provides a detailed picture of changes in the financial condition of U.S. families between 1995 and 1998. The financial situation of families changed notably in the three-year period. While income continued a moderate upward trend, net worth grew strongly, and the increase in net worth was broadly shared by different demographic groups. A booming stock market accounts for a substantial part of the rise in net worth, but the data also suggest that improvements in financial circumstances extended to many families that did not own stocks. The indebtedness of families grew, but less rapidly than their assets. Nonetheless, compared with 1995, debt repayments in 1998 accounted for a larger share of the income of the typical family with debt, and the proportion of debtors who were late with their payments by sixty days or more in the year preceding the survey was also higher.
Survey of Finance Companies, 2000
Authors: Dynan Karen E. , Johnson Kathleen W. , Slowinski Samuel M.
Published: December 2020

Against a backdrop of robust economic activity, the finance company sector expanded briskly over the second half of the 1990s. The value of receivables held by finance companies in the United States rose nearly 50 percent, or about 11 percent a year, between 1996 and 2000. Business lending remained finance companies' major line of activity; the importance to the sector of consumer lending and leasing declined slightly, and the importance of real estate lending rose a bit. These and other findings from the Federal Reserve's mid-2000 benchmark survey of finance companies, as well as developments in the sector since that time, are discussed in this article.
An Investigation of Co-movements among the Growth Rates of the G-7 Countries
Authors: Doyle Brian M. , Faust Jon
Published: December 2020

Early in 2000, after a decade of economic expansion, growth began to slow simultaneously in the large, advanced economies known as the Group of Seven (G-7)--Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States. The general slide in GDP growth fueled speculation that a period was emerging in which broad movements in the economies of the industrialized countries would be more closely linked. Proponents of this view argued that greater trade in goods and financial markets was leading to a greater synchronization of national economies. A rise in the co-movement of GDP among countries would have important implications for the making of national economic policies. Governments, for example, would need to take closer account of forecasts for conditions abroad in formulating forecasts for their domestic economies. The authors find, first, that the degree to which enhanced trade and financial linkages might be expected to increase the co-movement, or correlation, of economic growth among countries is far from clear. Then, examining the period from 1970 to the first quarter of 2002, the authors find that, indeed, the estimated correlation of growth across the G-7 has been higher in the current downturn than during the expansion of the 1990s. Rather than signaling a future of permanently higher synchronization, however, the rise is shown to be typical of business cycles over the past thirty years. Furthermore, estimates of correlation have not yet reached the peaks attained after earlier recessions. Overall, despite many changes in the international economy, the evidence does not reveal the arrival of a permanently higher correlation of growth rates among the G-7.
Recent Changes in U.S. Family Finances: Evidence from the 1998 and 2001 Survey of Consumer Finances
Authors: Aizcorbe Ana M. , Kennickell Arthur B. , Moore Kevin B.
Published: December 2020

Data from the Federal Reserve Board's Survey of Consumer Finances show a striking pattern of growth in family income and net worth between 1998 and 2001. Inflation-adjusted incomes of families rose broadly, although growth was fastest among the group of families whose income was higher than the median. The median value of family net worth grew faster than that of income, but as with income, the growth rates of net worth were fastest for groups above the median. The years between 1998 and 2001 also saw a rise in the proportion of families that own corporate equities either directly or indirectly (such as through mutual funds or retirement accounts); by 2001 the proportion exceeded 50 percent. The growth in the value of equity holdings helped push up financial assets as a share of total family assets despite a decline in the overall stock market that began in the second half of 2000. The level of debt carried by families rose over the period, but the expansion in equities and the increased values of principal residences and other assets were sufficient to reduce debt as a proportion of family assets. The typical share of family income devoted to debt repayment also fell over the period. For some groups, however--particularly those with relatively low levels of income and wealth--a concurrent rise in the frequency of late debt payments indicated that their ability to service their debts had deteriorated.
Recent Changes to a Measure of U.S. Household Debt Service
Authors: Dynan Karen E. , Pence Karen M. , Johnson Kathleen W.
Published: December 2020

Changes in levels of aggregate household debt in the United States may contain information about the current state of the nation&#x27;s economy and may affect its future direction. A commonly used measure of household indebtedness is the household debt service ratio (formerly known as the household debt service burden), published since 1980 by the Board of Governors of the Federal Reserve System. Recent changes in financial markets have prompted a comprehensive revision of this statistic. This article describes the revision and introduces a new measure, the financial obligations ratio, which adds recurring obligations--rent, auto leases, homeowners&#x27; insurance, and property taxes--to the traditional calculation of the debt service ratio. In total, these revisions change the level of the debt service ratio but do not substantively alter its trajectory over time. The article also presents separate estimates of the financial obligations ratio for homeowners and renters. The ratio for homeowners, which may summarize the effects of the recent refinancing boom on the financial obligations of homeowners, has risen gradually over the past decade; the ratio for renters has risen more steeply. The flat contour of the homeowner ratio in recent quarters suggests that homeowners may have rebalanced their portfolios toward lower-cost mortgage debt during the recent period of economic weakness.
Higher-Priced Home Lending and the 2005 HMDA Data
Authors: Avery Robert B. , Brevoort Kenneth P. , Canner Glenn B.
Published: December 2020

This article reviews the 2005 HMDA data, which have just been released to the public. The 2004 article covered a wide range of topics, including ways in which the expanded data might be used to aid fair lending enforcement, but this article is more limited: The focus here is primarily on the loan-pricing aspects of the data, including those that permit an assessment of the effects of the changing interest rate situation in 2004 and 2005 on the disclosure of higher-priced lending. To identify the effects on lending patterns of changing interest rates, the analysis presented here uses adjusted sets of the 2004 and 2005 HMDA data in an attempt to distinguish the loans that exceeded the pricing thresholds solely because of a changed interest rate situation from other higher-priced loans. This section of the analysis relies on monthly surveys of loan terms and pricing conducted by Freddie Mac and the Federal Housing Finance Board to help gauge the effects of changing interest rates over the period.

The Mortgage Market in 2011: Highlights from the Data Reported under the Home Mortgage Disclosure Act
Authors: Avery Robert B. , Bhutta Neil , Brevoort Kenneth P. , Canner Glenn B.
Published: December 2020

This article presents a number of key findings from a review of the data that mortgage lending institutions reported for 2011 under the Home Mortgage Disclosure Act (HMDA). The article documents home-lending activity reflected in the HMDA data and places the 2011 activity in historical context. It also examines changes in mortgage market concentration in recent years and in the credit scores of recent homebuyers. In addition, the article reviews patterns of lending across different racial or ethnic and income groups and across areas that differ in terms of housing market distress. Finally, it discusses how census updates may affect evaluations of the performance of banking institutions under the Community Reinvestment Act.
Changes in U.S. Family Finances from 2010 to 2013: Evidence from the Survey of Consumer Finances
Authors: Bricker Jesse , Dettling Lisa J. , Henriques Alice M. , Hsu Joanne W. , Moore Kevin B. , Sabelhaus John Edward , Thompson Jeffrey P. , Windle Richard
Published: December 2020

The Federal Reserve Board's Survey of Consumer Finances for 2013 provides insights into the evolution of family income and net worth since the previous time the survey was conducted, in 2010. The survey shows that, over the 2010-13 period, the median value of real (inflation-adjusted) family income before taxes fell 5 percent, while mean income increased 4 percent. The differential movements in median and mean incomes are consistent with increased income inequality over the 2010-13 period, though some of that differential growth simply reversed the cyclical decrease in income inequality that occurred between 2007 and 2010. Both median and mean real family net worth were little changed over the 2010-13 period, and the data suggest that the distribution of net worth also became more unequal over this period. Offsetting changes in asset ownership rates and asset prices left the middle of the net worth distribution relatively unchanged, while the top and bottom of the net worth distribution moved in different directions. This article reviews these and other changes in the financial condition of U.S. families, including developments in assets, liabilities, debt payments, and credit market experiences.
On Teaching Strategies of Junior English Reading from the Perspective of Discourse Function
Authors: Wang Ling
Published: December 2020

Reading is not only one of the difficult problems for students, but also one of the most important teaching parts for teachers. 126 students in Xingfeng Jiudu Middle School were taken as the research objects, and their English reading learning was investigated by means of questionnaire survey, so as to find problems existing in junior English reading teaching. Based on the three characteristics of discourse reading: integrity, comprehensiveness and applicability, the paper analyzes junior English reading teaching strategies from the three aspects of pre-reading, while-reading and post-reading. The research shows that under the guidance of discourse reading theory, using the method of discourse reading teaching is beneficial to stimulate students' interest in reading and improve their reading ability. For English teachers, it is also a good way to improve teaching efficiency and reduce teaching pressure.
The Cultivation of Discourse Ability in Middle School English Reading Teaching
Authors: Zhang Zhiyan
Published: December 2020

English has always been an essential part of junior high school curriculum. Improving students’ reading ability is not only the purpose of learning English for junior middle school students, but also an important means to acquire new knowledge. However, reading as one of the four basic skills required by the English course often keep students from getting high marks in the middle of the exam, although they took lots of time to read. This paper emphasizes the importance of English reading in junior middle school and analyzes the current situations and problems of students’ reading. It introduces the theories of reading and reading comprehension, discourse and discourse analysis, and the relationship between reading and discourse. The author puts forward some measures to improve the reading ability of students. There are many researches on discourse analysis about university, but the research is less involved in the secondary school, and the study of reading comprehension in junior middle school is even rarer. Therefore, the author thinks that it is very necessary to improve the discourse ability of junior high school students.
Research on Language-teaching Materials—An Evaluation of Extensive Reading Textbooks
Authors: Pan Li , Chen Ping
Published: December 2020

In second language teaching, materials play a unique role and the demand of developing language-teaching materials has been increasing. The textbook, an integral part of language-teaching materials, to some extent dominates the contents of teaching and learning and has a deep influence on curriculum. Textbooks for extensive reading apparently highlights this feature while some kind of series adopted in universities have several shortcomings in the representativeness of the articles and their variety of the categories, etc. which makes it hard to play an active role and have a positive impact in teaching and learning process. Some teachers ignore the development of this ability and the significant contribution they can make to evaluating and selecting textbooks. Thus, the author collects basic information from one series of textbooks and analyzes it systematically, and then shows overall comments with detailed suggestions on contents as: selecting more articles from representative writers; increasing articles about history and philosophy; selecting more current articles from magazines; adding more poems and attaching more detailed introductions about the authors and reference books to read. These suggestions will provide some implication for extensive reading textbook evaluation and selection, thereby, the selected textbooks can be at the good service for extensive reading teaching and teachers can get a self-development in the process.
RECONSTRUCTION OF THE SEMANTIC STRUCTURE OF GERMANIC-BALTIC-SLAVIC WORD FAMILIES (INDO-EUROPEAN *BHLENDH-)
Authors: Yermolenko S.
Published: December 2020

Being a research within the framework of the genetical word family approach to the comparative-historic study of Indo-European lexis and semantics, the article focuses on the semantic structure of the historical-etymological word family of the Indo-European root *bhlendh- encompassing words of the Germanic, Baltic and Slavonic languages. Analyzing the evidence provided by the reflexes of this word family’s underlying etymon, the author reconsiders the reconstruction of its primitive meaning and, outlining principal directions of its further semantic development, gives an explanation to certain peculiarities of this development which up till now remained unaccounted for.
Strike-Slip Earthquakes at the Northern Edge of the Calabrian Arc Subduction Zone
Authors: Calderoni Giovanna , Gervasi Anna , La Rocca Mario , Ventura Guido
Published: December 2020

We analyzed earthquakes of a swarm started in October 2019 in the Tyrrhenian Sea, at the northern border of the Calabrian arc subduction zone. The swarm is located in the same area where a subduction-transform edge propagator (STEP) shear- zone -oriented east–west is recognized from ocean floor morphology and submarine volcanoes. We computed focal mechanism, relative location, stress drop, corner frequency, and source directivity of the mainshock Mw 4.4 and of some aftershocks in the local magnitude range 2.3–3.7. Results indicate clearly that the mainshock occurred on a northwest–southeast-oriented fault, with right-lateral strike-slip motion, and it was characterized by a strong directivity of the rupture propagation from northwest to southeast. On the contrary, most of aftershocks were located on another strike-slip fault oriented northeast–southwest and had left-lateral kinematics. The kinematic features of these earthquakes indicate a strain field with the P-axis oriented north–south and the T-axis oriented east–west. Fault directions and stress field are in good agreement with the theoretical fracture model of shear zones associated with a STEP.
Performance Analysis in Multi-KPI Optimizations
Authors: Koç Gökhan , Variş Funda , Öçaldı Ferit , Kuran Murat
Published: December 2020

Importance of resource planning at airports, ports, logistic centers and similar operation points is increasing significantly each day due to competitions, intensities and irregularities in operations. Multi-objective optimization algorithms try to reach the user defined objectives of the related operations as much as possible but the performance of these algorithms starts to differ while the number of defined Key Performance Indicators (KPI’s) are increasing. In multi-KPI optimization algorithms, there are many issues and parameters to consider which affect the optimizer performances such as; relationship between KPI’s, the number of KPI’s, number of resources, tasks. In addition, due to some specific business rules in the operation, not every resource can be assigned to every task and the optimization algorithm needs to consider these rules when generating allocation plan. Within the scope of this study, an optimization algorithm which is developed by TAV Technologies is used to analysis optimizer performance changes according to the number of defined KPI’s. For the same resource and task group, the optimization algorithm configured with different KPI combinations and run repeatedly. Except for the KPI definitions, all other optimizer inputs were kept constant in all tests and the results were compared with each other. Specific business rules were ignored in this study to analysis test results clearly.
Emigración forzada de familias por la violencia en el sur de Sinaloa: experiencias trágicas y complejas
Authors: López López Roberto Carlos
Published: December 2020

Este trabajo estudia la migración forzada por la violencia en México, en particular en Sinaloa, en el contexto de la “guerra contra el narcotráfico”. El objetivo general del artículo es analizar el proceso de la emigración forzada por violencia y la integración en la sociedad receptora, no como etapas separadas, sino como parte de un proceso continuo de la migración y de las experiencias de las familias. Y lo que interesa es conocer esa experiencia del proceso, desde la emigración, el desplazamiento, hasta la integración. Estas experiencias están marcadas por la tragedia, la vulnerabilidad social y por el miedo. Pero, son las redes sociales y familiares las que han permitido la sobrevivencia de las familias, principalmente. El retorno definitivo parece lejano, porque sus pueblos fueron trastocados y no se les han garantizado las condiciones de seguridad ni restablecido la forma de vida de sus comunidades.
Los estudios de la comunicación más allá de la disciplina
Authors: Barrón Pérez Gabriel
Published: December 2020

En el marco de la frecuente preocupación que los estudiosos de la comunicación manifiestan respecto del lugar disciplinar que ocupan y de la relevancia que cobran los estudios socioculturales anclados en diferentes expresiones y tecnologías comunicacionales, el objetivo de este artículo es cuestionar teóricamente la disciplinarización de los estudios de la comunicación. El autor sondea el contradictorio empleo de los conceptos de “campo” y “mapa” como nociones que involucran la apertura disciplinar, examina las disciplinas como un ejercicio acotado del pensamiento y propone una imagen relacional, abierta y ontológica de la comunicación.
El Museo de la Solidaridad de la Unidad Popular al exilio (1971-1991). Una experiencia transnacional en tiempo de guerra fría cultural
Authors: Lebeau Elodie
Published: December 2020

Este artículo se propone presentar las redes transnacionales de solidaridad que permitieron la creación del Museo de la Solidaridad (1971-1973) durante la Unidad Popular y su desarrollo en el exilio a través del Museo Internacional de la Resistencia Salvador Allende (1975-1990), hasta su regreso a Chile en 1991. Analizando las interconexiones entre redes políticas, artísticas e intelectuales, nos proponemos destacar el papel central de las artes visuales en las manifestaciones de solidaridad con Chile durante el gobierno de Salvador Allende y, luego, contra la dictadura del general Pinochet. Enfocándose en los niveles locales, nacionales e internacionales, esta contribución privilegia el diálogo entre varias escalas geográficas y temporales y distintos enfoques disciplinarios. Se interesa a la vez en los discursos y estrategias de los agentes y de las instituciones participantes, incluso los de los artistas mediante el análisis de los imaginarios que emergen de las obras.
A New Harris Hawks-Cuckoo Search Optimizer for Multilevel Thresholding of Thermogram Images
Authors: Samantaray Leena , Hembram Sabonam , Panda Rutuparna
Published: December 2020

The exploitation capability of the Harris Hawks optimization (HHO) is limited. This problem is solved here by incorporating features of Cuckoo search (CS). This paper proposes a new algorithm called Harris hawks-cuckoo search (HHO-CS) algorithm. The algorithm is validated using 23 Benchmark functions. A statistical analysis is carried out. Convergence of the proposed algorithm is studied. Nonetheless, converting color breast thermogram images into grayscale for segmentation is not effective. To overcome the problem, we suggest an RGB colour component based multilevel thresholding method for breast cancer thermogram image analysis. Here, 8 different images from the Database for Research Mastology with Infrared images are considered for the experiments. Both 1D Otsu’s between-class variance and Kapur's entropy are considered for a fair comparison. Our proposal is evaluated using the performance metrics – Peak Signal to Noise Ratio (PSNR), Feature Similarity Index (FSIM), Structure Similarity Index (SSIM). The suggested method outperforms the grayscale based multilevel thresholding method proposed earlier. Moreover, our method using 1D Otsu’s fitness functions performs better than Kapur’s entropy based approach. The proposal would be useful for analysis of infrared images. Finally, the proposed HHO-CS algorithm may be useful for function optimization to solve real world engineering problems.
A Deep Learning Algorithm for Solar Radiation Time Series Forecasting: A Case Study of El Kelaa Des Sraghna City
Authors: Jallal Mohammed Ali , El Yassini Abdessalam , Chabaa Samira , Zeroual Abdelouhab , Ibnyaich Saida
Published: December 2020

Nowadays, the studies that address solar radiation (SR) forecasting tend to focus on the implementation of conventional techniques. This provides good results, but researchers should focus on the creation of new methodologies that help us in going further and boost the prediction accuracy of SR data. The prime aim of this research study is to propose an efficient deep learning (DL) algorithm that can handle nonlinearities and dynamic behaviors of the meteorological data, and generate accurate real-time forecasting of hourly global solar radiation (GSR) data of the city of El Kelaa des Sraghna (32°2’53”N 7°24’30”W), Morocco. The proposed DL algorithm integrates the dynamic model named Elman neural network with a new input configuration-based autoregressive process in order to learn from the seasonal patterns of the historical SR measurements, and the actual measurements of air temperature. The attained performance proves the reliability and the accuracy of the proposed model to forecast the hourly GSR time series in case of missing values detection or pyranometer damage. Hence, electrical power engineers can adopt this forecasting tool to improve the integration of solar power resources into the power grid system.

Authors: Cheng Jianfeng
Published: December 2020

With the proliferation of the Internet and smart mobile terminals, great progress has been made in the precision placement and benefit-sharing mechanism of commercial advertisements. Meanwhile, media marketing has become increasingly in-depth and precise. So far, mature theories have been proposed on consumer value and precision marketing. But further research is needed to mine the value from the big data on commercial precision marketing. To improve the accuracy of commercial precision marketing, this paper presents an evaluation index system (EIS) for commercial precision marketing based on improved attention-interest-desire-memory-action (ADIMA) model, and determines the principal evaluation indices through principal component analysis (PCA). Next, an artificial neural network (ANN) was established to evaluate commercial precision marketing, and optimized through k-means clustering (KMC). Finally, the optimized model was realized on MATLAB. The proposed EIS and ANN were proved scientific and effectiveness through simulations. The research results provide a reference for the application of the ANN in other fields of marketing.

Published: December 2020

The exponential growth of unstructured data and the ability of businesses to utilize such data in decision-making have led to competitive advantages. The knowledge provided by analyzing unstructured data is crucial for product developers or service providers because it might affect the sustainability of the business. Sentiment analysis is used to gain an understanding of the attitudes, opinions, and emotions expressed within an online review. Naïve Bayes (NB), logistic regression (LR), decision trees (DT), deep learning (DL), and support vector machines (SVM) were used to build a classification model. In the data mining settings, the classification accuracy is the best metric to highlight the best classifier. The DL classifier outperformed other models in terms of accuracy rate. Classifying customers' feelings toward a product or service is critical for providing actionable insights. Utilizing such models will help to analyze huge volumes of reviews, saving both time and costs.

Published: December 2020

Most students of mathematics education do not have truth-seeking. Therefore, it is necessary to do a corrective action in learning mathematics that can accustom students to tend to behave truth-seeking. The aim is to describe changes of students after the application of knowledge that accustoms truth-seeking through infusion mathematics learning. The research subjects were 25 students who were not truth-seekers at the beginning but experienced a change in the behavior of truth-seeking after the application of infusion learning. The data were collected through tests, direct observations, and interviews. The finding was that students experienced changes in truth-seeking behavior after participating in infusion learning for 10 meetings. This change was a habit that participants always do in response to a given mathematical problem.

Published: December 2020

Background: Supplier-induced demand (SID) refers to the concept that healthcare providers may deliver services to patients that are not medically necessary. An estimation of the extent to which this event has occurred can be insightful for policymaking and guiding health systems. This study aimed to investigate the extent to which SID presents itself during diagnostic MRI (magnetic resonance imaging) for primary breast cancer.
Methods: In this cross-sectional study, data were obtained using questionnaires from a random sample of 310 cases. To identify patients who were candidates for undergoing a necessary diagnostic MRI, we employed the international clinical guidelines with the confirmation of our expert panelists. With their assistance, a comprehensive index was created to screen those who were affected by SID.
Results: Of the respondents, 94.1% had undergone an unnecessary diagnostic MRI and, thus, were likely affected by SID, which indicated the lack of sovereignty of clinical guidelines in the prescription of MRI diagnosis imaging.
Conclusion: This study supported the SID hypothesis and the unnecessary demand for diagnostic MRI in primary breast cancer. In addition, our evidence indicated that excessive costs were imposed; these can positively influence policymakers’ decisions regarding healthcare management.

Background: Since the outbreak of the novel coronavirus disease-2019 (COVID-19) pandemics many orthopedic elective surgeries have been postponed all over the world. There are several guidelines for resuming elective surgeries during this crisis. In our center (Imam Khomeini hospital, Tehran, Iran), we resumed total joint arthroplasty (TJAs) surgeries using preoperative history taking and physical examination. Here, we report our experience.
Methods: From February 2020 to August 2020, we included 165 patients who underwent TJA [70 total hip arthroplasty (THA) and 95 total knee arthroplasty (TKA)] in Imam Khomeini hospital, a referral center for COVID-19. We followed each patient from the day of hospitalization to two weeks after discharge by telephone for clinical symptoms of COVID-19.
Results: Only one patient became infected with COVID-19 a week after discharge from the hospital, and other patients did not show any sign or symptoms within two weeks after the discharge.
Conclusion: We recommend resuming the elective surgeries using a careful physical examination and medical history for all patients, and in suspicious cases, referring to a specialized COVID-19 clinic for further investigation.
