Authors: Al-Amien Muhammad Muliya , Santosa Achadi Budi
Published: October 2022

Implementation of strategic management is believed to have a major influence on the achievement of institutional goals. This study aims to reveal the principal's strategy in implementing strategic management in the New Student Admissions (PPDB) program in Bantul district. Using a qualitative approach, this study selected the principal, and the PPDB team, as the main sources of information. Data collection techniques were carried out through interviews, observation, and document review. The results of the study revealed that the management strategy of PPDB SMK in Bantul district was carried out through: 1) Strategic Environmental Analysis, including; the advantages of the school, the economic background of the prospective student, geographical location, family background, and the origin of the prospective student's school. 2) Strategy Formulation, including; school promotion teams, fees, collaboration between institutions, strong partnerships between schools and the world of industry, relevance of majors based on prospective students' areas, to the clarity of information provided by the school. 3) Strategy implementation, including: increasing teacher and employee commitment, cost transparency, involvement of students and parents, ease of registration, excellent service, and promotional programs. 4) Evaluation and monitoring, periodically observing the level of interest of the registrants, and the level of achievement of targets. The implementation of PPDB's strategic management has not been carried out consistently, as a result, only a few schools have benefited from the implementation of this strategy.

In the era of education 4.0 which is characterized by the use of digital technology, the learning process is not limited to space and time. This allows the implementation of distance learning as a springboard for a new educational model. The Surabaya Aviation Polytechnic is a vocational education institution under the supervision of Direktorat Kelaikudaraan dan Pengoperasian Pesawat Udara (DKPPU). DKPPU as the airworthiness and operation authority has issued letter regarding the online learning system method due to the covid pandemic. One of the determining factors for the success of learning process is the use of appropriate learning media. The choice of learning media influenced by the characteristics of the learner. Therefore, it is important to know the learning styles of students. Thus, this study aims to determine the learning style tendencies of Surabaya Aviation Polytechnic cadets to obtain recommendations for selecting the right media in distance learning. The data collection process involved 900 cadets who were asked to fill out a learning style questionnaire which would later be analyzed quantitatively. For data triangulation, interview sessions were also held for selected cadets. From the results of data analysis, it was concluded that the Surabaya Aviation Polytechnic cadets tended to have visual learning styles (54% or 485 cadets) and auditory (13% or 121 cadets). So, the media recommendations are audio/video tutorials, interactive multimedia, and simulator software. However, a total of 126 cadets do not know their learning styles. They need to be assisted in-class during class learning to increase achievement motivation.

Este artigo apresenta resultados parciais de uma pesquisa que versa sobre a produção de podcast por um grupo de crianças pequenas de uma unidade pública de educação infantil. A pesquisa aproxima os campos da narrativa, numa visão benjaminiana de intercâmbio de experiências, tecnologias digitais de produção de podcast e educação infantil. A metodologia usada foi a pesquisa qualitativa e experimental, de natureza narrativa, a partir da qual se propôs coletar contações de histórias de crianças, produzi-las em podcasts e coletivizar essas produções em plataformas online. A coleta dos dados ocorreu por meio de observação participante, registro em diário de campo e em gravações de rodas de conversa e de contações em podcast. O material coletado foi interpretado de acordo com a hermeneuta fragmentária de Walter Benjamin. Fundamentados nesse autor, os pesquisadores tomam a criança como sujeito produtor de narrativas de experiências comunicáveis, cuja origem reside na tensão dialética entre o microcosmo individual e o macrocosmo social. Os resultados iniciais indicam que a produção de podcasts por crianças da educação infantil ampliam o espaço narrativo e se tornam importantes meios de dar voz às suas experiências.

Authors: Ribeiro Simone , Fortuna Danielle , Lima Jacqueline
Published: October 2022

O objetivo deste artigo é discutir de forma interdisciplinar - estabelecendo um diálogo, principalmente, entre educação e sociologia - a questão da contação de história e a contribuição da literatura africana e afro-brasileira na formação da identidade da criança negra na pré-escola. Para tanto, apresenta um relato de experiência desenvolvido numa escola do município de Duque de Caxias, na Baixada Fluminense, no estado do Rio de Janeiro, que atende crianças da pré-escola e ensino fundamental. A prática pedagógica em questão inseriu a literatura africana e afro-brasileira na rotina de uma turma de Educação Infantil, composta por 20 crianças na faixa dos cinco anos. O relato de experiência está ancorado, principalmente, nos pressupostos de Kabengele Munanga (2009) como base para a discussão teórica em torno da construção da identidade negra. Para o autor, o conceito de identidade no Brasil refere-se a uma realidade complexa que envolve fatores distintos como: histórico, linguístico e psicológico.

Using Voice Biomarkers to Classify Psychological Distress in Adult Helpline Callers: A Retrospective Observational Study (Preprint)
Authors: Iyer Ravi , Nedeljkovic Maja , Meyer Denny
Published: October 2022

BACKGROUND

Elevated psychological distress has demonstrated impacts on individuals’ health. Reliable and efficient ways to detect distress are key to early intervention. Artificial Intelligence has the potential to detect states of emotional distress in an accurate, efficient and timely manner.

OBJECTIVE

To automatically classify short segments of speech obtained from callers to national suicide prevention helpline services, according to low versus high psychological distress, using a range of voice biomarkers in combination with machine learning approaches.

METHODS

One hundred and twenty telephone call recordings were initially converted to 16-bit Pulse Code Modulation format. Short variable length segments of each call were rated on psychological distress using the Distress Thermometer by the responding counselor and a second team of psychologists blinded to the initial ratings (n=6). Nineteen voice biomarkers were derived using 40ms speech frames derived from each annotated segment. Candidate biomarkers were reduced using Lasso regression, validated by generalised additive mixed effects regression, accounting for non-linearity, autocorrelation and moderation by sex. Speech frames were then grouped using k-means clustering based on the selected biomarkers. Finally, component-wise gradient boosting was used to classify each speech frame according to low versus high psychological distress. Classification accuracy was confirmed via leave one out cross validation ensuring that speech segments from single callers were not used in both the training and test data.

RESULTS

Using twelve voice biomarkers, 686/747 speech segments were successfully classified, AUCROC = 93.8% (95% CI = 91.47, 94.6) and AUCPR = 94.8 (95% CI = 93.0, 96.5). When experiencing elevations in psychological distress, male speakers spoke with increasing loudness, higher frequencies in the 75th percentile of frequencies, but with poorer clarity of speech. In contrast, when experiencing psychological distress, the frequencies with which female callers spoke decreased in the highest quartile of frequencies, but exhibited increased clarity of speech.

CONCLUSIONS

The high level of accuracy achieved suggests possibilities for real-time detection of psychological distress in helpline settings and has potential uses in pre-emptive triage.

Tuberculosis - related knowledge, behaviors, stigmatizing attitude and discrimination among refugees, migrants, and general population in Jordan (Preprint)
Authors: Alsoukhni Majd , Khader Yousef , Abaza Hiba , Wilson Nevin , Satyanarayana Srinath
Published: October 2022

BACKGROUND

A better understanding of knowledge, attitude, practices (KAP) in the community and other issues related to tuberculosis (TB) can help in implementing evidence-driven activities to control TB in Jordan. This study aimed to assess TB- related knowledge, attitude, and behaviors among refugees, migrants, and general population, as well as assess their stigmatizing and discrimination attitudes toward TB patients, their social behavior towards TB, and their healthcare seeking behaviors.

OBJECTIVE

-

METHODS

A cross-sectional study was conducted among Jordanians, Syrian refugees (both urban and camp refugees), and migrants living in four governorates including Amman, Zarqa, Mafraq, and Irbid during the study period June-September 2021. A structured questionnaire was developed and used to collect the data via face-to-face interviews.

RESULTS

A total of 2302 (27.7% Jordanians, 25.7% urban refugees, 22.1% camp refugees, and 24.5% migrants) participated in this study. Out of the total, 90.1% of participants reported that the have heard of TB. However, 88.9% of Jordanians, 92.8% of urban refugees, 92% of camp refugees, and 90.5% of migrants had low level of TB-related knowledge. About 62.0% of urban refugees, 54.8% of Jordanians, 43.0% of camp refugees and 55.4% of migrants had moderate to high stigmatizing attitude toward TB patients. About 15.1% of Jordanians, 10.6% of urban refugees, 23.7% of camp refugees, and 16.1% of migrants had moderate to high level of discriminating attitude towards patients with TB. Camp refugees had significantly higher level of discriminating attitude towards TB patients than the other groups.

CONCLUSIONS

Jordanians, refugees, and migrants in Jordan had significant gaps in TB-related knowledge. Moderate to high level of stigmatizing attitude was reported by a considerable proportion of the study participants. This suggests a need for public health education programs to educate people on TB causes, signs and symptoms, mode of transmission and address TB-related stigma, especially among the most disadvantaged and affected communities in Jordan.

Published: October 2022

Background and objectives

In the BLISS-LN study, belimumab improved kidney outcomes in adult patients with active lupus nephritis. This 28-week open-label extension of BLISS-LN assessed belimumab’s safety and efficacy.

Design, setting, participants, & measurements

Eligible patients completing BLISS-LN received monthly intravenous belimumab 10 mg/kg plus standard therapy. End points included safety, open-label week 28 primary efficacy renal response (urine protein-creatinine ratio [UPCR] ≤0.7, eGFR no more than 20% below open-label baseline value or ≥60 ml/min per 1.73 m2, no prohibited medications) and complete renal response (UPCR <0.5, eGFR no more than 10% below open-label baseline value or ≥90 ml/min per 1.73 m2, no prohibited medications), and UPCR and eGFR by visit. Responses were also analyzed post hoc using the double-blind phase criteria.

Results

Of 257 enrolled patients, 255 were treated (safety population: n=123 switched from placebo-to-belimumab; n=132 remained on belimumab); 245 (97%) patients completed the study. Adverse events and serious adverse events were experienced by 62% and 4% of placebo-to-belimumab patients, respectively, and by 70% and 8% of belimumab-to-belimumab patients, respectively. One death occurred in the placebo-to-belimumab group. From open-label baseline to week 28, increases occurred in the proportions of patients achieving primary efficacy renal response (placebo-to-belimumab: from 60% to 67%; belimumab-to-belimumab: from 70% to 75%) and complete renal response (placebo-to-belimumab: from 36% to 48%; belimumab-to-belimumab: from 48% to 62%). Based on double-blind phase criteria, changes also occurred in the proportions achieving primary efficacy renal response (placebo-to-belimumab: from 54% to 53%; belimumab-to-belimumab: from 66% to 52%) and complete renal response (placebo-to-belimumab: from 34% to 35%; belimumab-to-belimumab: from 46% to 41%). The seeming decrease in response rates in the belimumab-to-belimumab groups was attributed to discontinuations/administration of glucocorticoids for non-SLE reasons as opposed to nephritis. Median UPCR and eGFR values were similar at open-label baseline and week 28.

Conclusions

No new safety signals were identified, and efficacy was generally maintained throughout the open-label phase.

Teaching Discussion Section Writing through a Genre-Based Approach to Undergraduates across Disciplines in China—A Novice EAP Teacher’s Classroom-Based Empirical Study
Authors: Liu Jiakai
Published: October 2022

This study illuminates the genre-based pedagogy delivered by a novice EAP teacher for teaching discussion section writing to cross-discipline undergraduates in China. Followed by the demonstration of specifics of genre teaching, the researcher tapped into the effectiveness of genre-based pedagogy through an examination of student-produced writing submissions. Autoethnography and qualitative research methods were used to analyze video-recording, teaching journals and students’ writing assignments and it was revealed that the focal Chinese English teacher who specialized in EGP was able to teach genre knowledge and research writing skills through autonomous learning and teaching preparation. Furthermore, the efficacy of genre teaching could be affirmed since most learner-writers successfully transferred genre knowledge and writing skills taught in the classroom to their writing. From this study, pedagogical implications are drawn to shed light on future teacher education that aims to help Chinese English teachers attain better genre-based research writing instruction.
Astrakhan Reserve Museum: Origins of the ‘Kalmyk’ Collection Analyzed
Authors:   Kalmyk Scientific Center of the RAS, Karueva Margarita
Published: October 2022

Introduction. A Joint Catalogue of Museum Items would essentially contribute to further preservation and scholarly exploration of Kalmyk cultural heritage, which is of even greater importance since quite a share of the latter had been lost in ethnic repressions and Deportation of 1943–1957. Associates of Kalmyk Scientific Center (RAS) have compiled a catalogue of the ‘Kalmyk’ collection at Astrakhan Reserve Museum and conduct systematic scholarly analyses of its elements. Goals. The paper aims at revealing origins of the mentioned ‘Kalmyk’ collection (except for Buddhist ritual objects and pho-tographs to be examined in another work). Results. The analysis shows the Collection was founded by Astrakhan Governorate Statistical Committee to have delivered a total of four items to the would-be Museum. ‘Mass’ arrivals of showpieces were ignited by the 1890 Kazan Science and Industry Exhibition’s arrangements — from three sources, namely: ethnic Kalmyks proper, Kalmyk People’s Executive Department, and Astrakhan Governorate Statistical Com-mittee. Subsequent years witnessed regular donations of Kalmyk-related items primarily from members of Peter the Great Society for the Study of Astrakhan Lands who succeeded not only in collecting but also in describing the submit-ted objects. So, the catalogues of 1890 and 1928 serve as unique sources on household life of the Kalmyks.
Sociopolitical Life in the North Caucasus and Problems of Its Ethnicization: Expert Opinions Reviewed
Authors:   Southern Scientific Center of the RAS, Gritsenko Galina
Published: October 2022

Introduction. The current ethnopolitical situation in the North Caucasus is characterized by instability. In sociopolitical life of region, it is ethnicization that tends to come to the foreground. Goals. The paper aims at clarifying functional essentials of ethnicization in the macroregion’s social life in the context of ethnopolitical dynamics. Materials and methods. The work employs a number of conflictology and riskology research methods. The empirical base rests on results of an expert survey. Results. The obtained research materials make it possible to comprehensively analyze functioning patterns inherent to ethnopolitical processes in the North Caucasian Federal District and outline conclusions as to impacts of ethnicization trends in the polyethnic environment. Most experts consider the ethnicization process has resulted from political and administrative miscalculations that ultimately give rise to ethnopolitical conflictogenity in the North Caucasus. The ethnicization is facilitated by ‘decision making risks’, such as absolutization of the ethnoterritorial principle in politics, imbalances of socioeconomic programs and projects, mythologization of ethnic histories, inefficient language policies. Some experts point out that this process is natural and objectively determined, with both progressive and destabilizing effects. The ratio between these characteristics is determined by the quality of ‘decision making’. The duality of assessments ultimately resumes that the phenomenon is functionally determined by subjective administrative efforts undertaken by contemporary political elites. The conflictogenity level of the ethnicization in sociopolitical life depends on the adequacy of decisions made, efficiency of administrative policy at large, and specifically the qualitative features of political elites.
Collection И-2 ‘Kalmyk Affairs Commission, 1825–1836’ (National Archive, Elista) as a Source in the History of Government Agencies and Pre-Revolutionary Kalmykia: Some Issues of Records Management Revisited
Authors:   Kalmyk Scientific Center of the RAS, Mandzhikova Larisa
Published: October 2022

Introduction. The article deals with the emergence and activities by the Kalmyk Affairs Commission which administered the Kalmyk Steppe of Astrakhan Governorate between 1826 and 1836. Given that the Kalmyks had a script of their own — todo bichig (Clear Script) — and were conducting extensive correspondence, it is necessary to analyze how they organized work with those documents. Of particular importance are insights into structures and contents of documents, scientific reference materials for Collection И-2 ‘Kalmyk Affairs Commission’ that make it possible to analyze and identify ef-forts once undertaken by the Commission in pre-revolutionary period. Goals. The article aims at exploring areas of the Commission’s activity, investigat-ing records management practices, analyzing types of documents. Results. Old Kalmyk language documents are unique written sources on everyday life of the Kalmyks in pre-revolutionary Russia. The research results shall serve a basis for further theoretical and applied works in public administration, center-periphery interaction, and records keeping practices pertaining to Clear Script documents.
УСИЛИТЕЛЬ МОЩНОСТИ КЛАССА G ДЛЯ ИНФОКОММУНИКАЦИОННЫХ СИСТЕМ
Authors: Леонтьев Е.В. , Коротков А.С. , Матвеев Ю.А.
Published: October 2022

В портативной и мобильной аппаратуре возрастают требования по эффективности, компактности и линейности усилителей мощности (УМ). Это особенно важно при передаче высокой мощности, когда УМ размещается в отдельном корпусе с собственным источником питания и системой охлаждения и вносит основной вклад в мощность потребления аппаратуры в целом. Для улучшения спектральной эффективности и помехозащищенности цифровых каналов связи широко используются OFDM-сигналы. Однако такие сигналы имеют высокое значение пик-фактора (PAPR – peak to average power ratio), что отражается на низкой эффективности типичного УМ класса AB. Для увеличения КПД усилителя
мощности используются более сложные структуры, например усилитель Доэрти или усилитель с отслеживанием огибающей (ETPA – envelope tracking power amplifier), представляющие наиболее перспективные решения. В данной работе реализован усилитель мощности класса G, который является частным случаем ETPA, с диапазоном рабочих частот 0.7–1,2 ГГц, выходной мощностью 32 дБм и КПД 46%; показаны достоинства и недостатки данной структуры.

ФС с использованием описанных в ГФ РФ методов воздушно-тепловой
сушки и волюмометрического титрования по методу Карла Фишера. Для уточнения результатов привлечены методы термогравиметрического анализа с масс-спектрометрическим детектированием (ТГА-МС), высокоэффективной жидкостной хроматографии в сочетании с диодно-матричным детектированием (ВЭЖХ-ДМД) и газожидкостной хроматографии с масс-спектрометрическим детектированием (ГЖХ-МС). Комплексное использование различных методов на примере анализа азитромицина дигидрата, цианокобаламина, трифенилметанола и (RS)-3-(нафталин‑1‑илокси)пропан‑1,2‑диола позволило уточнить состав примесей и провести их количественную оценку. Таким образом, применение описанных методов позволяет повысить достоверность определения содержания воды и ООР при анализе ФС.
La semilla de la vulnerabilidad: desventajas acumuladas en jornaleros de la agroindustria mexicana de exportación
Authors: Stabridis Omar
Published: October 2022

Objetivo: calcular la vulnerabilidad laboral de los jornaleros agrícolas mexicanos que trabajan en cultivos de exportación. Metodología: se estimó un modelo de mínimos cuadrados generalizados factibles y un modelo Poisson, considerando como determinantes la acumulación de desventajas: etnia, género y baja escolaridad. Resultados: las jornaleras y los jornaleros de baja escolaridad tienden a tener mayor vulnerabilidad laboral; los que trabajan para productores formales tienden a tener mayores riesgos de percibir salarios bajos; y los que trabajan para productores informales tienden a tener riesgos de padecer peores condiciones laborales. Limitaciones: se hacen estimaciones de vulnerabilidad en un solo periodo, lo que podría cuestionar la validez estadística si existiera autocorrelación, aunque no hay indicios de este hecho. Conclusiones: el hecho de ser mujer y tener baja escolaridad operan como desventaja ante los riesgos de vulnerabilidad laboral en jornaleras agrícolas que trabajan en cultivos de exportación, por lo que estimar la vulnerabilidad puede ser el primer paso para el establecimiento de una política pública dirigida a mitigarla.

Published: October 2022

Desde que la pandemia de la COVID-19 se originó en Wuhan, China, las mascarillas se han utilizado como parte del equipo de protección personal y, por lo tanto, se volvieron esenciales para la protección de la salud humana contra la COVID-19. En México, las mascarillas que más se emplearon en la población fueron las mascarillas quirúrgicas desechables, mascarillas filtrantes N95 y KN95. Sin embargo, durante los inicios y la etapa de mayor transmisión, la población por desconocimiento hizo mal uso de las mascarillas, afectando al personal del sector salud. En este documento se abordan las características de las mascarillas, los materiales de fabricación más comúnmente empleados y cómo es que funcionan a través de diferentes mecanismos: mecanismo por impacto inercial, mecanismo por intercepción, mecanismo de difusión y mecanismo de atracción electrostática, con el propósito de explicar aspectos básicos pero esenciales de las mascarillas, y necesarios recordar ante futuras pandemias. Finalmente, se menciona la importancia de las investigaciones científicas para el entendimiento y desarrollo de las mascarillas.

pesebre quiteño una iconografía polisémica
Authors: Cruz Medina Juan Pablo
Published: October 2022

El presente artículo busca evidenciar la manera en que el “pesebre quiteño” de los siglos XVII y XVIII recompuso el discurso iconográfico de los belenes napolitanos, y dio vida a una retórica visual tendiente a transmitir modelos ideales vinculados a formas de comportamiento tanto individuales como sociales. A partir del análisis iconográfico de una serie de figuras de pesebre, sumadas a los registros documentales que describen uno de los pesebres utilizados en el marco de la evangelización desarrollada en el Nuevo Reino de Granada, se demostrará que la iconografía del pesebre colonial se presentó como un mecanismo de configuración social. En medio de esto, lo ideal se presenta como núcleo del discurso visual, que se estructura a partir de la presencia de rasgos y formas propias de la retórica iconográfica del barroco.
Desagravios de Cristo en el aposentillo: aromas, cantos y pintura novohispana
Authors: Sacristán Ramírez Carolina
Published: October 2022

En la Nueva España del siglo XVIII, el sentido del olfato fue tan importante como la vista para comprender el contenido de algunas pinturas, entre ellas las imágenes que representan a Cristo en el aposentillo. Este artículo propone una nueva lectura de las obras anónimas sobre ese tema que resalta la importancia de los olores para su interpretación. El contraste entre hedores y fragancias que se vinculaban a la pintura ocurría en el marco del ritual del aposentillo; éste era una práctica devocional colectiva que prescribía ofrendas aromáticas y cantos dirigidos a Cristo para desagraviarle. El propósito de este ejercicio piadoso, cuidadosamentedescrito en un librito devocional de Nicolás de Espíndola intitulado Desagravios de Jesús, consistía en crear una experiencia didáctica olfativa, la cual permitía a los devotos aprender, por un lado, los significados simbólicos de la imagen al relacionarlos con diversos aromas; por otro lado, encarnar y asimilar el concepto teológico de la reparación. Ambas condiciones eran necesarias para que los creyentes se vinculasen emocionalmente con la imagen pintada, fortaleciesen su relación con lo divino y reafirmasen su pertenencia a una comunidad religiosa.
Dictadura y arte: lo indígena como modernidad artística y esencia de lo chileno en el gobierno de Carlos Ibáñez del Campo (1927-1931)
Authors: Herrera Styles Patricia , Zamorano Pérez Pedro Emilio , Vera Manríquez Rodrigo
Published: October 2022

El primer gobierno de Carlos Ibáñez del Campo en Chile, entre 1927 y 1931, fue una dictadura que, en consonancia con lo que ocurría en América Latina, intentó refundar distintos aspectos de la vida económica y cultural del país con la idea de un “Chile nuevo”. A este respecto, las artes y dentro de ellas la pintura, música, artes aplicadas y arquitectura, constituyen un espacio simbólico en donde el Estado quiso plasmar su impronta ideológica, ejerciendo una prerrogativa tutelar. Esta nueva sensibilidad, que privilegiaba valores indígenas (particularmente mapuche) y americanistas, fue entendida por el gobierno tanto como un discurso de identidad nacional, cuanto como una expresión particular de modernidad anclada en lo autóctono. El objetivo centralde este trabajo intenta demostrar cómo se articula este sistema que pone en relación principios políticos, estéticos y nacionalistas, al analizar las circunstancias y los actores que lo representan. Es decir, cómo se establece este correlato, a partir de algunos hitos relevantes, relacionados, entre otros, con la Escuela de Bellas Artes, el papel de Carlos Isamitt en esa entidad, y la presencia chilena en la Exposición Universal de Sevilla, en 1929.
Revisión crítica al Taller de Arte e Ideología
Authors: Rodríguez Pliego Circe , Gutiérrez Galindo Blanca
Published: October 2022

En el devenir del arte mexicano el muralismo ha sido el paradigma del trabajo colectivo; sin embargo, en los años setenta lo colectivo en el arte dio un giro con la asociación de jóvenes artistas que serían conocidos como Los Grupos, quienes llevaron a cabo una revisión de las nociones centrales de la estética moderna, como el sujeto creador, y de los postulados del muralismo. Uno de los pioneros de este movimiento hacia lo grupal fue el Taller de Arte e Ideología (TAI), colectivo multidisciplinario que en una clara herencia marxiana asumió una postura crítica sobre los asuntos del arte, que dejó de lado la separación entre teoría y praxis, entre otros antagonismos. El presente texto realiza una aproximación crítica a las propuestas del TAI, se posiciona en contra de a oposición colectivo-individuo en el trabajo artístico; además piensa la relación entre el arte y la política como la capacidad de producir experiencias innovadoras, que plantean nuevas condiciones de lo humano, antes que la presentación de contenidos que persiguen fines predeterminados.
Exhibir lo tropical: imágenes en la VIII Bienal Internacional Estudiantil de Costa Rica
Authors: Picado-García José Daniel , Solano-Meza Natalia
Published: October 2022

En 1992, el Colegio de Arquitectos de Costa Rica organizó la primera bienal de arquitectura para profesionales en el país y, desde 2004 se desarrollan las bienales estudiantiles de forma paralela. A partir de un análisis histórico que culmina en 2018, específicamente de las imágenes de propuestas arquitectónicas exhibidas en la VIII Bienal Internacional Estudiantil de Arquitectura de Costa Rica, se plantea que existe una tendencia en las propuestas estudiantiles a replicar características relacionadas con lo tropical. Este concepto ha sido puesto al servicio de búsquedas históricas en el campo profesional de la arquitectura en el país, precisamente, la de una identidad que refleje valores propios de la cultura arquitectónica nacional.
Between a Rockefeller and a Hard Place: Diego Rivera’s Man at the Crossroads and the Left in the 1930s
Authors: Zumoff Jacob A.
Published: October 2022

En 1933, Diego Rivera comenzó a pintar El hombre en la encrucijada, un mural en el Rockefeller Center de la ciudad de Nueva York. Después de que Rivera incluyó un retrato del revolucionario bolchevique Vladimir Lenin y rechazó la demanda de Nelson Rockerfeller de eliminarlo, el mural se cubrió primero y luego, en febrero de 1934, se destruyó. Ese mismo año, Rivera pintó un mural remodelado, Hombre, el controlador del universo, en el Palacio de Belles Artes de la Ciudad de México. El artículo actual examina esta controversia a través de la lente de la relación de Rivera con la izquierda comunista, en particular el Parti-do Comunista (pro Moscú), Liga Comunista de América (trotskista) y el Partido Comunista (Oposición) dirigido por Jay Lovestone, y argumenta que esta perspectiva proporciona un entendimiento más completo de los compromisos políticos del muralista y las políticas diversas expresadas en la obra de Rivera en aquel momento.
