Accuracy assessment of extreme learning machine in predicting soil compression coefficient
Authors: Ly Hai-Bang , Asteris Panagiotis G. , Pham Thai Binh
Published: June 2020

The compression coefficient (Cc) is an important soil mechanical parameter that represents soil compressibility in the process of consolidation. In this study, a machine learning derived model, namely extreme learning algorithm (ELM), was used to predict the Cc of soil. A total of 189 experimental results were used and randomly divided to construct the training and testing parts for the development and validation of ELM. Monte Carlo approach was applied to take into account the random sampling of samples constituting the training dataset. A number of 13 input parameters reflecting the experiment were used as the input variables to predict the output Cc. Several statistical criteria, such as mean absolute error (MAE), root mean square error (RMSE), correlation coefficient (R) and the Monte Carlo convergence estimator were used to assess the performance of ELM in predicting the Cc of soil. The results showed that ELM had a strong capacity to predict the Cc of soil, with the R value > 0.95. The convergence of results, as well as the capability of ELM were fully investigated to understand the advantage of using ELM as a predictor.
Bacterial Biofilm and Biofilm associated environmental protection

Published: June 2020

Biofilm is the syntrophic consortium of the microorganisms that mainly comprises of sessile groups of bacterial cells that adhere to the inanimate or living surfaces with the help of extracellular polymeric substance (EPS)and pili by forming a matrix composed of exopolysaccharide, proteins
and DNA(polymeric conglomeration). The sessile group of cells forming the biofilm develop intimate connection by Quorum Sensing (QS). EPS forming the biofilm comprises glycocalyx and chemically made up of carbohydrates, proteins and nucleic acid. EPS helps those adherent cells by embedding
them within a slimy layer and provides nutrients to the developing cells within the biofilm. Thus, it helps in pathogenesis of biofilm associated with infection and resistance due to the formation of impermeable layers to the penetration of antibiotics and drugs. Biofilm can be formed by the
microbes depending on various different factors including cellular recognition of specific or non-specific attachment sites on surface, nutritional cures or by exposure of planktonic cells to sub-inhibitory concentration of antibiotics. Besides this pathogenicity the biofilms are able in bioremediation.
In this review we are focused to exploit different strategies which are being used in bioremediation by the biofilms.

Educational Social Skills and Repertoire of Children Differentiated by Behavior and Sex
Authors: Assis-Fernandes Rafaela Pires , Bolsoni-Silva Alessandra Turini
Published: June 2020

Abstract Our study sought to compare mothers’ behavioral repertoire (educational social skills and negative practices) and maternal anxiety and depression indicators with children’s behaviors (behavior problems and social skills), by assessing the variables “sex” (boys and girls) and “occurrence of behavior problems”. The sample consisted of 20 children with behavior problems (clinical group), 20 without behavior problems (non-clinical group), their mothers and teachers. Reporting instruments were used with teachers and mothers and comparative analyzes were conducted between groups. The results indicated that the clinical group had higher rates of behavior problems and maternal depressive symptoms, whereas the non-clinical group showed more child social and educational social skills. Sex did not differ between groups. We concluded that maternal educational practices are more influenced by children’s behaviors than by their sex.

Published: June 2020

ABSTRACT Objective: To analyze the composition of macronutrients present in the milk of mothers of preterm newborn infants (PTNB) - protein, fat, carbohydrate, and calories - by gestational age (GA), chronological age (CA) and maternal variables. Methods: Longitudinal study that analyzed 215 milk samples from the 51 mothers of PTNB admitted in three Neonatal Intensive Care Units of Rio de Janeiro from May/2013-January/2014. Milk collection was performed by pickup pump, on a fixed day of each week until discharge. The spectrophotometric technique with Infrared Analysis (MilkoScan Minor 104) was used for the quantitative analysis. A sample of 7 mL of human milk was taken from the total volume of milk extracted by the mother. The data was grouped by GA (25-27, 28-31, 32-36, 37-40 weeks) and by CA (zero to 4, 5-8, 9-12, 13-16 weeks). Results: Protein, carbohydrate, fat and calories did not show any pattern of change, with no difference among groups of GA. When the macronutrients were analyzed by groups of CA, protein decreased, with significant difference between the first two groups of CA. Carbohydrates, fat and calories presented increasing values in all groups, without significant differences. Weight gain during pregnancy, maternal hypertension and maternal age were associated with changes in fat and calories in the first moment of the analysis of milk. Conclusions: There was a significant decrease in the levels of protein during the first eight weeks after birth. CA may be an important factor in the composition of human milk.

Published: June 2020

Resumo: Não apenas muitas garotinhas nos Estados Unidos e em outros lugares brincam de escolinha, mas, por vezes, ao crescerem, se tornam professoras, um ponto em que o relato de brincadeiras se escolinha assume uma nova função narrativa e discursiva. Por meio de teorias da narrativa e da performance e da análise de discurso, examinamos relatos de brincadeiras de escolinha contados como parte de um estudo qualitativo multilocal de histórias de vida de professoras norte-americanas dos anos iniciais do ensino fundamental graduadas recentemente e em formação. Analisamos estas narrativas com um olhar sobre a cultura pop e os tempos de menina a partir de meados da década de 1990 até seu final e outro sobre como o brincar de escolinha é colocado tanto em prática quanto discursivamente. Implicações para a preparação e a identidade profissional de professores, além da face sexista do trabalho docente, concluem o artigo.

Unlocking the Full Evolutionary Potential of Artificial Metalloenzymes Through Direct Metal-Protein Coordination
Authors: Biggs George S. , Klein Oskar James , Boss Sally R. , Barker Paul D.
Published: June 2020

Generation of artificial metalloenzymes (ArMs) has gained much inspiration from the general understanding of natural metalloenzymes. Over the last decade, a multitude of methods generating transition metal-protein hybrids have been developed and many of these new-to-nature constructs catalyse reactions previously reserved for the realm of synthetic chemistry. This perspective will focus on ArMs incorporating 4d and 5d transition metals. It aims to summarise the significant advances made to date and asks whether there are chemical strategies, used in nature to optimise metal catalysts, that have yet to be fully recognised in the synthetic enzyme world, particularly whether artificial enzymes produced to date fully take advantage of the structural and energetic context provided by the protein. Further, the argument is put forward that, based on precedence, in the majority of naturally evolved metalloenzymes the direct coordination bonding between the metal and the protein scaffold is integral to catalysis. Therefore, the protein can attenuate metal activity by positioning ligand atoms in the form of amino acids, as well as making non-covalent contributions to catalysis, through intermolecular interactions that pre-organise substrates and stabilise transition states. This highlights the often neglected but crucial element of natural systems that is the energetic contribution towards activating metal centres through protein fold energy. Finally, general principles needed for a different approach to the formation of ArMs are set out, utilising direct coordination inspired by the activation of an organometallic cofactor upon protein binding. This methodology, observed in nature, delivers true interdependence between metal and protein. When combined with the ability to efficiently evolve enzymes, new problems in catalysis could be addressed in a faster and more specific manner than with simpler small molecule catalysts.

Foods such as fruit, vegetables, and cereals, and particularly whole grain, are rich in dietary fibre and have been proved to have multiple beneficial effects for the human health. The present research was designed to assess some eating practices related to fibre-rich foods in different countries, namely Argentina, Croatia, Hungary, Latvia, Portugal, and Romania. A cross-sectional descriptive study was undertaken on a sample of 4905 adult participants, obeying all ethical guidelines for this type of research. Regarding the data treatment, basic statistics was complemented with the tree classification analysis.
Generally, the results show a low consumption of salads and vegetables,
i.e., up to 11 servings/week (for 78.2% of participants), with Croatia in the lead (86.6%). Regarding fruit, a great majority of data also indicated low consumption (92.3%), most especially for Latvia (98.3%). The level of consumption of whole cereals was also low (72.6%), particularly for Latvia (90.0%). The tree classification analysis showed
that while the first discriminant variable for the consumption of salads and vegetables was country, followed by education, for the consumption of fruit, it was country and then sex, and finally, for the consumption of whole cereals, it was sex and followed by country. The results allowed the conclusion that the consumption of foods rich in dietary fibre was very low for these countries, highlighting the necessity to implement strategies that incentivise the consumption of such foods, which are very important for a healthy diet.

Published: June 2020

Breast milk often becomes insufficient to meet the nutritional needs of infants from 6 months onwards, and thus there is a need to introduce complementary diets. This study aimed at formulating complementary diets
by combining fermented provitamin A biofortified maize flour with germinated lentil flour in ratios of 100%, 90:10%, 80:20% and 70:30%. They were evaluated for proximate composition, functional properties, mineral composition, carotenoid content, anti-nutrient content, amino acid profile and organoleptic properties. The protein contents ranged from 10.65 to 28.17%, 100%; germinated lentil flour (O6R) had the highest value, while the energy values of the diets ranged from 395.62 to 404.13 Kcal/100 g. The foaming capacity, foaming stability, water absorption capacity and bulk density increased, while the oil absorption
capacity and dispersibility decreased as the lentils increased. The swelling capacity ranged from 39.92 to 69.42 %. The viscosity increased as the temperature dropped. The potassium and calcium contents increased
with increased in the addition of lentils. Sodium and iron contents were high in the sample AM4 (fermented 100% provitamin A biofortified maize). The carotenoid content ranged from 0.80 to 1.27 mg/100 g. The anti-nutritional contents (phytate and oxalate) were reduced, while the trypsin inhibitor increased. The most abundant essential amino acid was leucine, while glutamic acid was the most abundant non-essential amino acid. It was observed that as lentil seed increased, the amino acids increased too. The values obtained for essential amino acid met up with the recommended standards, except for tryptophan, methionine, threonine and cystine. The sample TU1 (70% fermented provitamin A biofortifed maize and 30% germinated lentils seed) was the most acceptable by the panelists compared to the commercial baby formula (control). Therefore, this complementary diet may serve as means to combat protein-energy malnutrition in infants. A further research should be carried out on in-vivo study of this complementary diet.

Published: June 2020

Aflatoxin contamination of maize is a serious food safety problem worldwide. Despite the widespread consumption of maize in Nigeria, there
is limited data on aflatoxin contents of maize vended in open markets in Ondo state, Nigeria. A total of 140 maize samples randomly purchased from major markets in four locations in Ondo state, were screened for total aflatoxins using an ELISA method. Exposure and health risk assessments were performed for the maize consumers by the deterministic and Margin of exposure (MOE) approaches, respectively. About 99% of the maize were contaminated with total aflatoxins (range: 0.65–265 µg/kg; mean: 125.9 µg/kg). Aflatoxin levels exceeding the 4 µg/kg set by the European Union for total aflatoxins were found in 88% of the maize whilst more than one half contained at least 100 µg/kg aflatoxins. The average probable daily intake values were 830, 332 and 138 ng/kg bw/day for the average children, adolescent and adult populations, respectively. Consequently, MOEs for the respective populations were 0.20, 0.51 and 1.23, suggesting a high level of health risk for consumers of maize vended in open markets in Ondo state due to high aflatoxin levels. Maize farmers and households in Ondo state need urgent
aflatoxin mitigation interventions.

Published: June 2020

The elimination of pollutants in water sources is a widely studied issue with the purpose of preserving the environment. In this work, the use of lemon peel (citrus lemon) as a bio-sorbent in the removal of Pb (II) and Ni (II) is studied, varying the temperature, adsorbent dose, and particle size. The materials were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) analysis, to determine the bio adsorbent’s physicochemical properties. FTIR and EDS techniques confirmed the precipitation of ions on the adsorbent after the adsorption process. It was found that the optimal conditions according to the Response Surface Methodology (RSM) are: particle size for Ni (II) of 1 and 0.355 mm, adsorbent dose 0.077 g and 0.117 g, and temperatures of 34 and 45 ºC, for Pb (II) and Ni (II), respectively. The results reported that the Dubinin-Radushkevich isotherm and the pseudo-second-order model are more in line with the experimental data, suggesting that the adsorption process is driven by physisorption and occurs in multilayers. Thermodynamic parameters suggest that the process is exothermic for Ni (II) and endothermic for Pb (II), and irreversible. The binary study showed that there is no competition for active sites between the ions.
The impact of inventory holding costs on the strategic design of supply chains
Authors: Bolaños-Zúñiga Liliana , Vidal-Holguin Carlos Julio
Published: June 2020

The explicit consideration of inventory holding costs for the strategic design of supply chains has not been sufficiently addressed in scientific literature. A possible cause is that usually supply chain optimization models are deterministic and linear or mixed-integer linear, while forecasting methods and inventory control systems are stochastic and non-linear. It is clear, however, that inventory costs might have a significant impact on optimal supply chain configuration and on distribution systems expansion or contraction. This article presents a practical strategy that considers an item-by-item inventory control system by means of a Monte Carlo simulation model as a starting point to include inventory holding costs in a supply chain optimization model. Three strategies to include inventory costs in the objective function were analyzed: The Square Root Law (SRL), the potential functions that relate average inventory with warehouse throughput, and the estimation of average inventories by simulation. The results suggest that the SRL should not be used unless unusual assumptions hold and that potential functions are a very good approximation to consider inventory costs for supply chain configuration.
LEITURA MULTIMODAL DO POEMA “ESCRÍNIO”, DE MANOEL DE BARROS

Published: June 2020

A valorização da modalidade escrita dentro da sociedade contemporânea ─ intensa, e, muitas vezes, exclusiva ─ tem recebido inúmeras críticas de estudiosos que defendem haver limitação de significados produzidos como consequência dessa realidade. Nessa perspectiva, este trabalho tem por objetivo uma análise intersemiótica entre o poema “Escrínio” e as fotografias do início do século passado, representativas dos espaços mencionados no texto literário. Tal proposição se respalda na possibilidade de alargamento de significados produzidos a partir da leitura em diversas modalidades, incrementadas com a discussão sobre o papel da fotografia (BARTHES, 2015) Enquanto as fotos revelam pontualmente a realidade de uma cidade em seu esplendor, vivido no início do século XX o poema satiriza tal visão (CAMPOS, 2011), retratando e enaltecendo lugares e pessoas várias vezes marginalizadas pelos jornais corumbaenses da época (SOUZA, 2008).

Published: June 2020

A caracterização de hábitos, costumes e tradições particulares dos ribeirinhos tem grande relevância regional, pois as cidades na Amazônia foram criadas inicialmente a partir dos rios, com seus trapiches e portos. O objetivo da pesquisa foi descrever as construções sociais e físicas dos ribeirinhos na Amazônia com enfoque nas características e particularidades de identidade cultural. A realização da pesquisa ocorreu com a análise do discurso e dados secundários utilizados para descrever e conhecer o objeto de estudo e tentar compreender o universo particular das populações tradicionais sob a perspectiva de uma correlação a outras populações estudadas.  Foram feitas três visitas entre os anos de 2013 e 2015 com a realização de entrevistas e observação ao longo dos percursos entre as cidades de Oriximiná e Santarém, na Amazônia, avaliando a inserção cultural no contexto geográfico, econômico e político. Dividindo a população que vive na Amazônia, pode-se, de forma comparativa, distribuí-la em um espaço social específico para os ribeirinhos quando comparada aos moradores amazônicos das grandes metrópoles, pois possuem habitus, capital econômico e cultural diferenciados, ou seja, a divisão por categorias sociais de percepção, princípios de visão e de divisão, diferenças nas práticas, nos bens possuídos e nas opiniões expressas.

IDENTIDADE ÉTNICA, AUTOGOVERNANÇA E ATIVOS BIOLÓGICOS: UM OLHAR A PARTIR DA EXPERIÊNCIA EM UMA COMUNIDADE QUILOMBOLA
Authors: Carvalho Josué De Lima , Lino Ynis Cristine de Santana Martins , Santos Ticiane Lima dos
Published: June 2020

Dentre as diversidades de povos tradicionais, este trabalho tem por objeto de estudo investigar uma experiência de autogestão de ativos biológicos em “Comunidades Remanescentes Quilombolas” constituídas pelos descendentes dos escravos negros que, no processo de resistência à escravidão, originaram grupos sociais que ocupam um território comum e compartilham características culturais, sociais e econômicas até os dias de hoje. Seguindo os conceitos já expressos a piscicultura, como prática, é uma forma de busca para alternativas à reprodução social. Portanto, o objetivo deste estudo se encontra na busca entre a relação da gestão do território em uma comunidade quilombola e a sua produção agropecuária coletiva utilizando conceitos relacionados a autogestão e reconhecimento de ativos biológicos. Utilizou-se o Casing (RAGIN; BECKER, 1992) enquanto método e o objeto desse estudo se concentrou na comunidade Quilombola Forte do Castelo em Tomé-Açu, no estado do Pará. Evidenciou-se que a comunidade pratica a autogestão a partir da autogovernança, a qual possibilita a construção de instituições legítimas. Os resultados obtidos expressam a influência que a comunidade tem da autogovernança e a sua relação com a piscicultura com meio de produção.

Published: June 2020

Este artigo é resultado de uma análise interdisciplinar do conto O Rebelde (1893), do escritor Inglês de Sousa, inserido na estética Realista/Naturalista da literatura brasileira. O conto faz referência ao movimento revolucionário, político e social de Belém do Pará, ocorrido no período de 1835 e 1840, chamado “Cabanagem” partindo de um olhar da Literatura, como forma de expressão artística da sociedade possuidora de historicidade e como fonte documental para a produção do conhecimento histórico. Parte do princípio de que todo texto é representação de realidades, com regras próprias de produção, como observamos em Chartier (1990). E o objetivo é demonstrar possíveis relações entre representações históricas do movimento cabano e representações literárias, através do conto de Inglês de Sousa. Como aporte teórico foram utilizados os historiadores Rocque (1984), Ricci (2001), Lima (1986) e teóricos da área de Teoria Literária Nunes (2003), Eagleton (2006), Zola (1982).

THE VEGETABLE WORLD IN OLEKSII DOVHIY’S POETRY
Authors: Strokal Oleksandr
Published: June 2020

The article deals with the features of verbalization of the plant world in Oleksii Dovhiy’s poetic language. The study found that the natural world for the primitives reflected the entire Universe – its structure, essence, links, which could not be explained or understood by them. That is why all the phenomena and realities of the environment were anthropomorphized. The components of the plant world made up the largest part of conceptual concepts in the worldview of Ukrainians. The language appeared a certain medium for such representations, reflected by the figurative symbolic semantics of the words. Poetry became a special form for representation of these meanings, whereas just in the poetic text the deep symbolism of numerous anthropomorphized images of nature could be shown fully and vividly. In Oleksii Dovhiy’s poetic texts realities of the flora are presented quite clearly and multifaceted because a poet is aware of their important role in the Ukrainian cultural tradition. The largest part of these units are presented by trees and their parts. These are the most commonly used lexemes and their derivatives: birch, beech, elm, willow, cherry, pear, oak, guilder rose, maple, poplar, apple tree, etc. Usage of the lexemes with diminutive semantics allows a poet to convey the inner state of the lyrical hero and establish a deeper connection with the reader. Plant world is involved in the creation of feminine and masculine images in the text and in the process of sacralization of a particular locus.
THE IMAGE OF UKRAINIANS IN POLES’ MENTALITY. A CASE STUDY BASED ON JOURNALIST PIOTR POGORZHELSKI’S BOOK “UKRAINIAN BORSCH”
Authors: Godun Cristina
Published: June 2020

The article aims at presenting the geopolitical, social and cultural image of Ukraine, seen through the eyes of the author, the Polish journalist Piotr Pogorzhelski, former Kiev correspondent of the National Radio Polonia. This imagological portrait, which carries us through the history and national stereotypes, means to bring Ukraine closer to Romanian readers. Despite the neighborhood and the presence of the Ukrainian community in Romania, Romanians don’t know their northern neighbours very well, older generations show preconceived ideas and a distorted historical memory. Piotr Pogorzhelski’s book, translated into Romanian and published in 2015 shortly after the dramatic events on the Maidan Nezalezhnosti, aims to raise public awareness and draw attention to the political and socio-cultural potential of Ukraine and the Ukrainians. The same goal pursues «The Ukrainian Borsch» in Poland, a country where Ukraine is a frequent topic of discussion in the press, because the connection between Poland and Ukraine has always been very strong, despite some historical difficulties. The majority of Poles treat Ukraine with a sense of deep affection due to family roots or nostalgia for the western territories of Ukraine, which once belonged to Poland. And yet, among the Poles who manifest openness and an increased interest in Ukraine, the image of this country and its inhabitants is due to narrow negative stereotypes. On the background of current political events and taking into the account the lack of knowledge about Ukraine in Romania, «The Ukrainian Borsch» seems to be an indispensable and appropriate tool for shaping the collective portrait of Ukrainians and contemporary Ukrainian society.
THE “CYROPAEDIA” OF XENOPHON AND THE “HISTORY OF THE ROMAN EMPIRE” OF HERODIAN: STRUCTURAL SIMILARITIES THROUGH CENTURIES OF ANCIENT GREEK HISTORIOGRAPHY (A REVIEW OF THE RECEPTIONS IN MODERN CLASSICAL PHILOLOGY)
Authors: Dovbyshchenko Fedir
Published: June 2020

The present article is an attempt to analyze the narrative strategies and scope of Xenophon’s “Cyropaedia” and Herodian’s “History of the Roman Empire” as viewed within the modern reception in classical philology. This paper presumes that the narrative techniques of writing historiographical biographies in antiquity might be the same across the whole period which separates the two works in question. The distance in time did not result in radical changes of the narrative structure in historiography, as the example of Xenophon’s “Cyropaedia” and Herodian’s “History” shows. The analysis of the ancient histories, as this article argues, can be conducted not only to understand the level of their factual reliability, but also to describe their possible impact on contemporary readers or listeners. It is also shown in the present article that the narrative structure of the two histories is far from being that of the non-fictional prose, and that modern classicists tend to consider them as fictional texts. Moreover, the whole ancient historiography, unlike the modern one, has to be treated as fiction, for the strategies of creating it were similar to the narrative strategies of other genres.
LANGUAGE POLICY IN THE REYKMISSARIAT OF UKRAINE
Authors: Zinkevich Andrej
Published: June 2020

The article deals with some issues of language policy in the Reichskommissariat of Ukraine (1941-1944) in the context of competition between different concepts of the Third Reich leadership in relation to the occupied eastern territories. In this regard, along with the problem of attitude of the new authorities to the Ukrainian language, the issue of introduction of Latin script in Ukraine and teaching German to the local population is raised. The language policy implemented in the Reichskommissariat for the first time is the result of an internal struggle between the main forces of the occupation administration: the Ministry of the Eastern Occupied Territories, the Reichskommissariat Ukraine, the Wehrmacht (in its area of responsibility in Ukraine) and branches of the industrial and transport structures of the Reich working in Ukraine. The legislative basis of the language policy in Ukraine was never officially approved until the end of the occupation, so the main source of information about the language regulation was the letter of the Ministry for the Occupied Eastern Territories dated January 13, 1942 about the foundations of the language policy, which in its basic provisions supported the trend towards gradual Ukrainianization of the population (excluding Ukrainian Germans). The most noticeable correction of the language policy took place in the sphere of teaching German to the local population. The needs of the military industry forced economic structures to lobby for the elimination of the ban on teaching German to Ukrainians, which in turn was reinforced by the general policy line of the Ministry for the Eastern occupied territories to involve the Ukrainian people in the fight against Bolshevism.

Authors: Salomatin A. Y. , Koriakina A. S.
Published: June 2020

The ethnic factor is important in the development of federalism. ethno-linguistic architecture and cultural-religious structure are the main elements. Switzerland and India are diff erent models of ethnic federalism. The Swiss model of federalism is cantonal-communal. Switzerland consists of 26 cantons; there is a multi-ethnic composition of the population. Switzerland escaped ethnic separatism. The state has centuries of experience in reconciling linguistic and cultural diff erences. The Indian model is postcolonial. The state is multi-ethnic. Indian federalism is highly centralized. India has a unique ethnic, linguistic and religious composition.
Formation of the North–South Seismic Zone and Emeishan Large Igneous Province in Central China: Insights from P-Wave Teleseismic Tomography
Authors: He Chuansong , Santosh M.
Published: June 2020

The geodynamic features of the north–south seismic zone (NSSZ) and the formation of the Emeishan large igneous province (ELIP) in China remain controversial. In this study, we conducted detailed P-wave teleseismic tomography studies in the NSSZ and adjacent regions. The results revealed large high-velocity anomalies beneath the Songpan–Ganzi Block and the South China Block, possibly representing large-scale lithospheric delamination. We further identified low-velocity structures at 50–200 km depths in the western and southern parts of the NSSZ, suggesting an upwelling asthenosphere induced by delamination and the absence of a rigid lithosphere. Two high-velocity structures beneath the Sichuan basin and the Alashan block were also revealed, which may represent the lithospheric roots of these structures. These rigid lithospheric roots may have obstructed the eastward extrusion of the Tibetan plateau and led to stress accumulation and release (triggering earthquakes) in the Longmenshan Orogenic Belt and the northern part of the NSSZ. Because of this obstruction, the eastward extrusion was redirected southeastward to Yunnan in the southern part of the NSSZ, which led to stress accumulation and release causing earthquakes along the Honghe and Xiaojiang faults. The results from this study reveal a high-velocity structure with a subducted slab-like appearance that may represent vestiges of the Paleo-Tethys oceanic lithosphere, which subducted beneath the ELIP and initiating large-scale mantle return flow or mantle upwelling, contributing to the formation of the ELIP.
CEO Duality and Firm Value: Evidence from Mexico
Authors: Dávila-Velásquez Juan Pablo , Lagos-Cortés Diógenes
Published: June 2020

Regulators and corporate governance activists are lobbying companies to eliminate the CEO duality; however, the effectiveness of this recommendation is questioned given that empirical evidence has found conflicting results. This document studied the effects of the CEO’s duality on the value of the company in a sample of 104 Mexican companies that were publicly traded between 2000 and 2013. For this, different regression models were estimated using the ordinary least squares technique. The firm value was measured through Tobin’s Q and ROA. Empirical results showed that there is no relationship between CEO duality and value after controlling for board characteristics such as size and independence.

Published: June 2020

Se presentan aquí, los resultados de una investigación teórico-práctica, en la cual se abarcó el eslabón de suministro, en una cadena de abastecimiento, en una empresa del sector azucarero en el Valle del Cauca. Para la selección de proveedores de insumos críticos, se aplicó la metodología multicriterio, considerando criterios que iban más allá del costo, tomando como referencia una clasificación de insumos de acuerdo a su criticidad en términos de sostenibilidad, para el proceso productivo. Inicialmente, se hizo una caracterización y una selección de los insumos críticos, en términos de sostenibilidad. Igualmente, se identificaron los proveedores para los insumos seleccionados. Luego, y en consenso con un comité escogido al interior de la empresa, se seleccionó y aplicó el método de jerarquía analítica AHP (Analytic Hierarcgy Process). Finalmente, se tomó la decisión más acorde a los requerimientos reales de la organización, los cuales consideraban como criterio principal la sostenibilidad, para alcanzar la competitividad y el desarrollo sostenible. Esto contribuirá con el tiempo, a que la organización sea económicamente viable, ambientalmente soportable y socialmente equitativa.

Background: ART introduction was a breakthrough step and a boon for HIV infected and AIDS patients. Since the launch of world’s second largest ART programme by Indian Government on 1st April 2004, duration and quality of patient’s life has improved significantly. But after years of treatment with first line ART drugs clinical deterioration is being observed in several patients. This study was done to find out clinical symptoms present in treatment failure cases and to look for any improvement after one year of second line ART.Methods: This is a Single tertiary care teaching hospital based clinical (assessment with investigation) continuous longitudinal, prospective and retrospective, observational study at ART plus Centre, Kanpur. All patients on 1st line ART treatment in the centre were screened for treatment failure as decided by SACEP from 2016 to 2018. Treatment failure was suspected in patients on first line ART treatment with deterioration or non-improvement of clinical symptoms which was later confirmed by immunological and virological test.Results: Study included 71 (61%) female and 47 (39%) male patients. Heterogeneous mode of transmission of disease was most common (97 (82%)) followed by Blood transfusion (11 (9%)). HIV infection prevalence in age group of 30 to 40 years was 54 (45%). Most common clinical features of the patients with first line ART treatment failure were weight loss (105 patients), chronic diarrhoea (56 patients), fever (34 patients), and cough (24 patients). After treatment for one year with 2nd line ART drugs above symptoms were reduced to 20, 5, 5 and 12 patients respectively.Conclusions: First line ART failure was most common among female patients and heterogeneous mode of transmission was the commonest. Most common clinical features of first line ART failure were weight loss, chronic diarrhoea, fever, and cough which were reduced significantly after treatment with 2ndline ART drugs for one year.
