Marxismo y socialismo mexicano en Redes, de Paul Strand y Carlos Chávez, con música de Silvestre Revueltas
Authors: Saavedra Leonora 
Published: March 2021

Redes (1934-1935), película mexicana ideada y filmada por el fotógrafo modernista Paul Strand, es reconocida como obra fundamental –panfletaria para algunos– del cine mexicano. Entre músicos se le conoce por la música que para la banda sonora compuso Silvestre Revueltas. Redes fue producida de acuerdo a lineamientos educativos generados en la SEP por Narciso Bassols (1931-1934), secretario, y Carlos Chávez, director del Departamento de Bellas Artes (1933-1934). La película se ocupa de las tribulaciones de un grupo de pescadores pobres y explotados de Veracruz; pero Redes es un film no sólo sobre sino, sobre todo, para los trabajadores. El objetivo de este trabajo consiste en colocar la creación intelectual y física de Redes en el contexto de las ideas políticas y sociales de Bassols, Chávez y, como resultado de su cercanía con éstos, Strand. Más particularmente, mostraré cómo el argumento de la película y su misma cinematografía siguen fielmente la teoría clásica marxista sobre el capitalismo y la explotación y enajenación del trabajador en él, atendiendo a la visión colectivista de la SEP de Bassols. Utilizando documentos de archivo, hago un recuento de la radicalización política de Strand en México, muestro la clara autoría intelectual del fotógrafo (a pesar de que el film se presenta en los créditos como obra del director Fred Zinnemann), discuto los lineamientos de la SEP dentro de los cuales Strand trabajó y hago una lectura marxista del film para señalar su mensaje político específico. Eduardo Contreras Soto y James Krippner han mostrado que la asociación de Revueltas con el proyecto de Redes fue tardía y la música, creada a posteriori. Aquí discuto solamente la utilización en la banda sonora de significadores musicales que facilitan la lectura política del filme por parte del espectador-trabajador, canalizan su respuesta emocional y anclan su percepción en un contexto específicamente mexicano.

Abstract

OBJECTIVE
To estimate the prevalence of extended-spectrum cephalosporin-, carbapenem-, and fluoroquinolone-resistant bacteria of the family Enterobacteriaceae in the feces of hospitalized horses and on hospital surfaces.

SAMPLE
Fecal and environmental samples were collected from The Ohio State University Galbreath Equine Center (OSUGEC) and a private referral equine hospital in Kentucky (KYEH). Feces were sampled within 24 hours after hospital admission and after 48 hours and 3 to 7 days of hospitalization.

PROCEDURES
Fecal and environmental samples were enriched, and then selective media were inoculated to support growth of Enterobacteriaceae bacteria that expressed resistance phenotypes to extended-spectrum cephalosporins, carbapenems, and fluoroquinolones.

RESULTS
358 fecal samples were obtained from 143 horses. More samples yielded growth of Enterobacteriaceae bacteria that expressed resistance phenotypes (AmpC β-lactamase, OR = 4.2; extended-spectrum beta-lactamase, OR = 3.2; and fluoroquinolone resistance, OR = 4.0) after 48 hours of hospitalization, versus within 24 hours of hospital admission. Horses hospitalized at KYEH were at greater odds of having fluoroquinolone-resistant bacteria (OR = 2.2). At OSUGEC, 82%, 64%, 0%, and 55% of 164 surfaces had Enterobacteriaceae bacteria with AmpC β-lactamase phenotype, extended-spectrum beta-lactamase phenotype, resistance to carbapenem, and resistance to fluoroquinolones, respectively; prevalences at KYEH were similarly distributed (52%, 32%, 1%, and 35% of 315 surfaces).

CONCLUSIONS AND CLINICAL RELEVANCE
Results indicated that antimicrobial-resistant Enterobacteriaceae may be isolated from the feces of hospitalized horses and from the hospital environment. Hospitalization may lead to increased fecal carriage of clinically important antimicrobial-resistance genes.

Published: March 2021

We report electrochromism of M-MOF-74 (M=Mg, Mn, Co or Zn), a honeycomb nano-framework in which hexagonally packed one-dimensionalarrays of metal cations are coordinated with 2,5-Dihydroxyterephthalic acid linker. Raman spectroscopy upon electrochemical doping combined with density functional theory calculations reveals redox reactions of the linker while the metal cations stay divalent asprobed by X-ray photoemission spectroscopy. Excellent adhesion of the MOFs to glass allows synthesis of quality thin films to be implemented into electrochromic devices that exhibit promising colour contrast and durability.

O objetivo principal neste trabalho consistiu em analisar e comparar índices de (des) conforto térmico humano em um município de clima semiárido. Para isso foram adquiridos e utilizados equipamentos termo-higrômetros automáticos datalogger Akso AK170, sendo esses distribuídos espacialmente em onze pontos (dez em áreas urbanizadas e um em área rural), durante um período de 32 dias, em Caicó-RN. De posse dos dados horários de temperatura e umidade relativa do ar (maio/junho), realizaram-se análises estatísticas descritivas e aplicaram-se três índices de conforto humano, a saber: Índice de Desconforto (ID), índice de Temperatura Efetiva (TE), e o Índice de Temperatura e Umidade (ITU). Os resultados indicaram que o município de Caicó está propenso aos efeitos do processo de urbanização, registrando-se frequências de temperaturas mais elevadas nas áreas urbanizadas, especialmente nas de menor arborização e maior concentração de pavimentos urbanos. Em termos médios a maior parte da população de Caicó sente desconforto devido ao calor (ID), as temperaturas ficaram sempre acima do considerado calor moderado (TE) e de acordo com o ITU a classificação foi de extremamente desconfortável. Portanto, é imprescindível minimizar o os efeitos da ilha de calor no município a fim de se obter melhores índices de conforto térmico humano. Human (dis) comfort indices in a semi-arid municipality in Brazil A B S T R A C TThe main aim of this study was to analyse and compare the human thermal (dis)comfort indices in a Brazilian municipality with a semi-arid climate: Caicó, in the state of Rio Grande do Norte. Akso AK170 thermo-hygrometer data loggers were acquired for this purpose, which were distributed at eleven points in the study area – ten in built-up areas and one in a rural area – over a 32-day period covering the months of May to June. Having collected the time- and date-stamped temperature and relative humidity data, descriptive statistical analyses were conducted using three human comfort indices: discomfort index (DI), effective temperature index (ETI), and temperature-humidity index (THI). The results indicate that the municipality under study is affected by urbanization processes that propitiate higher temperatures in the built-up areas, especially where there are fewer trees and more of the roads are paved. On average, most of the population of Caicó feels discomfort because of the heat (ID), and the temperature always remains above the range rated as moderately hot (ETI). The municipal climate was classified as “extremely uncomfortable” by the THI. It is therefore of the utmost importance to minimize the effects of the heat island in the municipality to improve the human thermal comfort indices.Keywords: Urban climate. Caicó-RN.

Sabe-se que a precipitação é uma variável de difícil estimativa em especial nas regiões semiáridas. Diversos estudos e avanços já foram obtidos na estimativa de precipitação, mas ainda se necessita desenvolver modelos que possam proporcionar estimativas mais reais. Com o intuito de contribuir nessa linha de pesquisa, este estudo teve como objetivo avaliar a relação existente entre a precipitação e o índice de área foliar no bioma caatinga. Utilizou-se o método de correlação linear simples entre a precipitação e o índice de área foliar. Os dados de precipitação utilizados neste estudo foram obtidos pelo modelo ETA e os do índice de área foliar foram obtidos pelo sensor MODIS. As relações estatísticas mostraram uma boa correlação entre o índice de área foliar e a precipitação. Assim, conclui-se que o entendimento da dinâmica do índice de área foliar espacial e temporal pode ajudar no entendimento da dinâmica espacial e temporal da precipitação na caatinga. A estimativa da precipitação pelo modelo ETA pode ser melhorada com o uso do índice de área foliar.Palavras-chave: sensoriamento remoto, LAI, modelo ETA, precipitação, caatinga. Linear correlation between rainfall and Leaf Area Index of the Caatinga biome A B S T R A C TIt is known that precipitation is a variable that is difficult to estimate, especially in semiarid regions. Several studies and advances have already been obtained in the estimation of precipitation, but there is still a need to develop models that can provide more real estimates. In order to contribute to this line of research, this study aimed to assess the relationship between rainfall and the leaf area index in the caatinga biome. The simple linear correlation method between precipitation and leaf area index was used. The precipitation data used in this study were obtained by the ETA model and those of the leaf area index were obtained by the MODIS sensor. The statistical relationships showed a good correlation between the leaf area index and precipitation. Thus, it is concluded that the understanding of the dynamics of the spatial and temporal leaf area index can help in the understanding of the spatial and temporal dynamics of precipitation in the caatinga. The estimation of precipitation by the ETA model can be improved with the use of the leaf area index. Keywords: remote sensing, LAI, ETA model, rainfall, caatinga.

Published: March 2021

Program counter-discourse (kontra wacana) adalah program yang berusaha menciptakan “a way of thinking that opposes an institutionalized discourse”. Selama ini wacana kaum fundamentalis, kaum radikal hinga kelompok-kelompok teroris sudah terlembaga sedemikian rupa di Indonesia melalui proses yang panjang dalam sejarah sosial politik negeri ini. Teka-teki yang muncul atas motif apakah yang mendasari makin maraknya kaum profesional yang berkecukupan tergiur untuk menjadi tentara Negara Islam Irak dan Suriah (NIIS) atau yang lebih dikenal dengan ISIS (Islamic State of Iraq and Syria) belum juga terpecahkan secara komprehensif. Hingga saat ini, sudah sekitar 518 warga negara Indonesia diduga bergabung dengan ISIS dan menurut catatan Sidney Jones dari Institute for Policy Analysis of Conflict (IPAC), sudah lebih dari 800 warga negara Indonesia yang sudah berangkat dan bergabung dengan gerakan “teroris” tersebut di Suriah. Oleh karena itu, perlu membangun kontra wacana sebagai benteng untuk membendung upaya “cuci otak” yang dilakukan oleh pihak-pihak yang tidak bertanggung jawab. Program ini tentu saja tidak akan berjalan tanpa dukungan dari berbagai pihak terkait, terutama pihak-pihak yang paham dengan permasalahan ini. Padahal, di sisi lain, upaya dan program nyata untuk memerangi terorisme yang bersifat straight-forward dan sistematis seharusnya terus digalakkan dan terlembaga. Harapannya, program kontra wacana ini dapat mereduksi dan menghantam ideologi-ideologi yang menyimpang yang selama ini dianut oleh gerakan-gerakan sosial politik keagamaan.
The Integration of Artificial Intelligence in Drug Discovery and Development
Authors: Archer Matthew , Germain Stephanie 
Published: March 2021

ABSTRACT

The application of Artificial Intelligence (AI) has risen astronomically within modern society, but its influence within the pharmaceutical and healthcare sectors is set to be hugely significant.
Artificial intelligence can be defined as the idea and development of computers that are able to perform tasks traditionally thought of as requiring human intelligence and subsequent learning.
In this article, we will bring to light some of the diverse roles and select limitations of AI, from drug discovery and development, to marketing and purposing drugs for clinical use. The pathway of drug discovery is well documented to be time and financially intensive. With the digitsation of data and advancements in technology combined with the cumbersome process of drug discovery and subsequent development, it creates a perfect environment for integration of AI.
AI can be implemented in all stages of drug discovery from helping to identify potential targets and molecules through to aiding the trial design and finally it has uses with ongoing monitoring of post market products.
We consider this to be pivotal time in using AI to revolutionise the discovery process, allowing us to move away from traditional drug discovery with high value drugs and towards an enhanced number of discoveries with shorter lead time. It should be appreciated that there will be challenges still posed by this integration; data acquisition and specifically high-quality data, interpretation of the data and whether this can translate into real world results.
The Dynamics Transformation of Public Policy Making in Indonesian Democracy
Authors: Al Fatih Andy 
Published: March 2021

Public policies are purposed, basically, to solve public problems and for the sake of public welfare. They should, therefore, be made thoughtfully, implemented successfully, and give pleasant impacts to the target groups. This article is related to the dynamics transformation of public policy making in indonesian democracy. In centralistic political system, national government (executive body) controlled more essential public affairs. As the result, most public policies were much engineered and directed, mostly, to the needs of the in power. The tendentious public policies were abused for personal, group, and cronies’ interests of the in authority officials. The people were left behind, served as object of development, and stayed poor. It happened for decades. The people could not stand it any longer and struggled for a reformed government resulting in regional autonomy. Regional autonomy seems promising for the people’s prosperity. In this era, legislative body tends to control power. The people set hopes and wait for happiness. In fact, some members of parliament only show power. They control many walks of lives. They represent themselves rather than the people. They somewhat abuse power and make public policies for their own gains. The people are left behind again and still get disappointed. Here, a paradox occurs. The paradox must be sorted out well. The hot discussion begins. The actors blame to one another.

Objective — to establish the clinical and pathogenetic role of the isolation of the middle mass molecules of different fractions (aminopeptide — AF, peptide — PF, nucleotide — NF, chromatophore — CF) in exhaled breath concentrate (EBC) in pneumonitis in rheumatoid arthritis (RA) patients, their relationship with the parameters of respiratory moisture excretion, spirography and pressure in the pulmonary artery.
Materials and methods. EBC (pulmonary expirates) were studied in 31 patients with RA (mean age 46 years, the ratio of men to women 1 : 2), among whom moderate and high degree of disease activity was established in 67.7 % of cases, III and IV stages — in 54.8 %, the extra­articular form of the disease — in 61.3 %, systemic osteoporosis — in 83.9 %, seropositivity for rheumatoid factor — in 80.7 %, for antibodies to cyclic citrullined peptide — in 77.4 %. To determine the middle mass molecules in the expirates and blood serum, a screening method was used with the precipitation of proteins with trichloroacetic acid and the determination of the light absorption spectra of the acid­soluble fraction.
Results and discussion. Interstitial pneumonitis was diagnosed in 51.6 % of the number of RA patients, which was accompanied by fibrosing alveolitis in 18.8 % of cases, rheumatoid nodules in the lungs — in 12.5 %, obliterating bronchiolitis — in 6.3 %, with the ratio of restrictive, mixed and obstructive types of dysfunctions of external respiration 6 : 2 : 1, while the disease proceeded with a significant increase in AF indicators in 74.2 % of patients and the ratio «EBC/blood» (e/b) PF level in 77.4 % against the background of a decrease in AFe/b (at 71.0 %), NFe/b (at 54.8 %, CFe/b (at 74.2 %) and the ratio of surface tension caused by high­ and low­molecular substances in 83.9 %, and the composition of expirates was closely interrelated with the state of hemodynamics of the pulmonary circulation and bronchopermeability, depended on the rate and volume of respiratory moisture release, long­term use in the complex treatment of patients with an immunosuppressant of cytotoxic action, folic acid antagonist methotrexate. Conclusions. The nature of the respiratory excretion of middle mass molecules of different fractions determines the pathogenesis of pneumopathy in RA patients, which depends on the clinical, radiological and sonographic signs of the disease, and the study of EBC can be used to predict the course of the pathological process and monitor the effectiveness of therapeutic measures.

Ao entrar no ambiente do Ensino Superior surge um novo conceito de vida para o estudante, que passa a ter responsabilidades e compromissos que outrora não tinha. Esta mudança na sua rotina pode gerar sentimentos de ansiedade e estresse, fatores que influenciam no desempenho diário do estudante. O objetivo dessa pesquisa foi avaliar a presença de estresse, seus níveis e fatores socioeconômicos associados entre graduandos de um curso de Odontologia. Nesse estudo transversal e observacional, de abordagem quantitativa, estudantes matriculados no curso de Odontologia de uma instituição de ensino superior privada (n=135) responderam a um questionário autoaplicável contendo questões sociodemográficas e o Inventário de Sintomas de Stress para Adultos de Lipp (ISSL). Os dados coletados foram analisados por estatística descritiva e as associações realizadas por meio do teste qui-quadrado. A maioria dos participantes cursava o décimo semestre (29,63%), era do sexo feminino (68,15%), solteiros (88,89%), sem filhos (90,37%), com idade média de 23,03±3,50 anos, apresentando estresse (62,22%) caracterizado pela prevalência da fase de resistência (86,90%) e sintomas psicológicos (48,81%). O sexo feminino e estudantes que optavam pelo custeio dos estudos na modalidade financiamento estavam significativamente mais estressados (50,37%; χ2=16,79; p=0,000 e 34,81%; χ 2=8,22; p=0,042, respectivamente). Conclui-se que o estresse esteve presente no transcorrer do curso de graduação em Odontologia, principalmente na fase de resistência. Entre as variáveis socioeconômicas analisadas, o sexo feminino e o tipo de custeio dos estudos na modalidade financiamento estiveram associados a condição.
