Authors: Zhao Xinying , Xu Hailin , Li Yan , Liu Yufan , Guo Caixia , Li Yanbo
Published: March 2023

Epidemiological data indicate atmospheric particulate matter, especially fine particulate matter (PM2.5), has many negative effects on human health. Of note, people spend about 90% of their time indoors. More importantly, according to the World Health Organization (WHO) statistics, indoor air pollution causes nearly 1.6 million deaths each year, and it is considered as one of the major health risk factors. In order to obtain a deeper understanding of the harmful effects of indoor PM2.5 on human health, we used bibliometric software to summarize articles in this field. In conclusion, since 2000, the annual publication volume has increased year by year. America topped the list for the number of articles, and Professor Petros Koutrakis and Harvard University were the author and institution with the most published in this research area, respectively. Over the past decade, scholars gradually paid attention to molecular mechanisms, therefore, the toxicity can be better explored. Particularly, apart from timely intervention and treatment for adverse consequences, it is necessary to effectively reduce indoor PM2.5 through technologies. In addition, the trend and keywords analysis are favorable ways to find out future research hotspots. Hopefully, various countries and regions strengthen academic cooperation and integration of multi-disciplinary.
Attractor-Like Dynamics Extracted from Human Electrocorticographic Recordings Underlie Computational Principles of Auditory Bistable Perception
Authors: Melland Pake , Curtu Rodica
Published: March 2023

In bistable perception, observers experience alternations between two interpretations of an unchanging stimulus. Neurophysiological studies of bistable perception typically partition neural measurements into stimulus-based epochs and assess neuronal differences between epochs based on subjects' perceptual reports. Computational studies replicate statistical properties of percept durations with modeling principles like competitive attractors or Bayesian inference. However, bridging neuro-behavioral findings with modeling theory requires the analysis of single-trial dynamic data. Here, we propose an algorithm for extracting nonstationary timeseries features from single-trial electrocorticography (ECoG) data. We applied the proposed algorithm to 5-min ECoG recordings from human primary auditory cortex obtained during perceptual alternations in an auditory triplet streaming task (six subjects: four male, two female). We report two ensembles of emergent neuronal features in all trial blocks. One ensemble consists of periodic functions that encode a stereotypical response to the stimulus. The other comprises more transient features and encodes dynamics associated with bistable perception at multiple time scales: minutes (within-trial alternations), seconds (duration of individual percepts), and milliseconds (switches between percepts). Within the second ensemble, we identified a slowly drifting rhythm that correlates with the perceptual states and several oscillators with phase shifts near perceptual switches. Projections of single-trial ECoG data onto these features establish low-dimensional attractor-like geometric structures invariant across subjects and stimulus types. These findings provide supporting neural evidence for computational models with oscillatory-driven attractor-based principles. The feature extraction techniques described here generalize across recording modality and are appropriate when hypothesized low-dimensional dynamics characterize an underlying neural system.

SIGNIFICANCE STATEMENTIrrespective of the sensory modality, neurophysiological studies of multistable perception have typically investigated events time-locked to the perceptual switching rather than the time course of the perceptual states per se. Here, we propose an algorithm that extracts neuronal features of bistable auditory perception from largescale single-trial data while remaining agnostic to the subject's perceptual reports. The algorithm captures the dynamics of perception at multiple timescales, minutes (within-trial alternations), seconds (durations of individual percepts), and milliseconds (timing of switches), and distinguishes attributes of neural encoding of the stimulus from those encoding the perceptual states. Finally, our analysis identifies a set of latent variables that exhibit alternating dynamics along a low-dimensional manifold, similar to trajectories in attractor-based models for perceptual bistability.
Rule Abstraction Is Facilitated by Auditory Cuing in REM Sleep
Authors: Pereira Sofia Isabel Ribeiro , Santamaria Lorena , Andrews Ralph , Schmidt Elena , Van Rossum Mark C.W. , Lewis Penelope
Published: March 2023

Sleep facilitates abstraction, but the exact mechanisms underpinning this are unknown. Here, we aimed to determine whether triggering reactivation in sleep could facilitate this process. We paired abstraction problems with sounds, then replayed these during either slow-wave sleep (SWS) or rapid eye movement (REM) sleep to trigger memory reactivation in 27 human participants (19 female). This revealed performance improvements on abstraction problems that were cued in REM, but not problems cued in SWS. Interestingly, the cue-related improvement was not significant until a follow-up retest 1 week after the manipulation, suggesting that REM may initiate a sequence of plasticity events that requires more time to be implemented. Furthermore, memory-linked trigger sounds evoked distinct neural responses in REM, but not SWS. Overall, our findings suggest that targeted memory reactivation in REM can facilitate visual rule abstraction, although this effect takes time to unfold.

SIGNIFICANCE STATEMENTThe ability to abstract rules from a corpus of experiences is a building block of human reasoning. Sleep is known to facilitate rule abstraction, but it remains unclear whether we can manipulate this process actively and which stage of sleep is most important. Targeted memory reactivation (TMR) is a technique that uses re-exposure to learning-related sensory cues during sleep to enhance memory consolidation. Here, we show that TMR, when applied during REM sleep, can facilitate the complex recombining of information needed for rule abstraction. Furthermore, we show that this qualitative REM-related benefit emerges over the course of a week after learning, suggesting that memory integration may require a slower form of plasticity.

Published: March 2023

Meta-analyses from 2018–2022 have shown that obesity increases the risk of various cancers such as acute myeloid lymphoma, chronic myeloid lymphoma, diffuse beta cell lymphoma, Hodgkin's lymphoma, leukemia, multiple myeloma, non-Hodgkin's lymphoma, bladder, breast, cholangiocarcinoma, colorectal, ovarian, esophageal, kidney, liver, prostate, thyroid, and uterus. Contextually, obesity, and its comorbidities, is the largest, most lethal pandemics in the history of mankind; hence, identification of underlying mechanisms is needed to adequately address this global health threat. Herein, we present the metabolic and hormonal mechanisms linked to obesity that might etiologically contribute to neoplasia, including hyperinsulinemia and putative places in the insulin-signaling pathway. Excess insulin, acting as a growth factor, might contribute to tumorigenesis, while abundant ATP and GDP supply the additional energy needed for proliferation of rapidly dividing cells. Our observations in the Ecuadorian cohort of subjects with Laron syndrome (ELS) prove that obesity does not always associate with increased cancer risk. Indeed, despite excess body fat from birth to death, these individuals display a diminished incidence of cancer when compared to their age- and sex-matched relatives. Furthermore, in cell cultures exposed to potent oxidizing agents, addition of ELS serum induces less DNA damage as well as increased apoptosis. ELS individuals have absent growth hormone (GH) counter-regulatory effects in carbohydrate metabolism due to a defective GH receptor. The corresponding biochemical phenotype includes extremely low basal serum concentrations of insulin and insulin-like growth factor-I, lower basal glucose and triglyceride (TG) levels, and diminished glucose, TG, and insulin responses to orally administered glucose or to a mixed meal.
Mobile Technology-Powered Education in Developing Countries
Authors: Zhou Min
Published: March 2023

Mobile learning, which is supported by mobile applications and devices such as smartphones and tablets, has gained significant popularity due to the widespread adoption of mobile technology and continuous improvements in internet infrastructure. This trend is reflected in the growing use of mobile learning worldwide. Research has shown that smartphones play a crucial role in promoting student development, particularly in learning and research (Esechie et. al., 2022). Compared to traditional learning approaches, mobile technology-powered learning is more flexible and convenient, as it can be conducted at any time and in any places. Students can access learning resources via mobile devices, complete assignments and tests online, and more. Existing studies suggest that most students are receptive to mobile device-assisted learning, and student attitudes, strategies, and preferences are the main factors influencing their mobile learning experience (Tang et al., 2019).

Detoxification of lignocellulosic hydrolysates by in situ formation of Fe(0) nanoparticles on activated carbon
Authors: Sajab Mohd Shaiful , Santanaraj Jude , Mohammad Abdul Wahab , Kaco Hatika , Harun Shuhaida
Published: March 2023

The breakdown of lignocellulosic biomass into fine chemicals is an essential subsequence process of bioconversion technology. However, the manner of decomposition can contribute significantly to inefficiency of the overall conversion. Certain low molecular weight byproducts of the lignin and hemicellulose within lignocellulosic hydrolysate are toxic, making it necessary to carry out a complicated detoxification process. In this study, detoxification of hydrolysate was performed by the adsorption and catalytic oxidation, as well as the integration of both techniques on the targeted compounds of acid-soluble lignin (ASL) and synthetic furfural. In spite of the high selectivity of its adsorption and catalytic oxidation, by relying on just these techniques, the hydrolysate was unable to completely remove ASL and furfural. However, by depositing Fe(0) nanoparticles on the surface active sites of the adsorbent, the integration of the adsorption-oxidation technique provided sufficient performance in the removal of ASL and furfural.
Enhanced conductive fiber of multiwall-carbon-nanotubes templated carbonization of cellulose
Authors: Zhang Shaobo , Niu Gengwu , Yu Haibia , Huang Jintian
Published: March 2023

It has been reported that a conductivity of 100 S/cm of carbonized cellulose is obtained when the carbonization temperature is higher than 2000 °C. However, such high temperatures require expensive equipment and are energy consuming. In this study, carbonized multi-walled carbon nanotubes (MWCNTs)/cellulose composites fibers with a conductivity of 105 S/cm were prepared. They were prepared based on cellulose (in the carbonization temperature 1000 °C), a naturally abundant and low-cost material. The mechanism of improving electrical conductivity was studied. The MWCNTs played the role of a conductive bridge between the nano-carbonization cellulose blocks. As the template of cellulose graphitization, MWCNTs not only can improve the degree of cellulose graphitization but can also change the microstructure of carbonization cellulose from nano-spheres to sheets. This preparation method can be applied to other carbon materials to make highly conductive fibers or various conductive structure materials, such as a conductive film or an aerogel. This study broadens the application of cellulose in the field of electricity. The obtained conductive fibers have great potential in a range of applications, such as wearable electronics and low-cost energy storage.

Authors: Jha Vijay , Kumari Nirupa , Prasad Birendra , Ranjan Tushar
Published: March 2023

To investigate the production of cellulases and hemicellulases from Aspergillus niger MTCC9931, solid state fermentation (SSF) was performed using 10 different lignocellulosic materials derived from agrowastes, i.e., rice straw, rice husk, wheat straw, corn cob, sugar cane bagasse, saw dust, banana stalk, Eichhornia, Parthenium stalk, and residual fruit pulp. Among these agrowastes, the maximum yield of reducing sugars (116.46 ± 2.56 g/mL) was observed with residual fruit pulp. Further, the same substrate showed the highest endoglucanase (389.1 ± 0.44 IU/g), MCC-adsorbable endoglucanase (3.4 ± 0.14 IU/g), cellulase (12.0 ± 0.13 IU/g), and FPase (4.9 ± 0.64 IU/g) activities. Sawdust showed the maximum xylanase activity (7478.0 ± 6.51 IU/g), and corncob showed maximum β-glucosidase activity (79.87 ± 1.15 IU/g). The maximum activities of all enzymes were observed at 72 h of SSF under shaking conditions. A. niger MTCC9931 can be concluded to be an important strain for potential applications in saccharification. The enzymatic hydrolysates of the agrowastes were used as substrates for ethanol production by Saccharomyces cerevisiae MTCC174. The maximum yield (35.34 g/L) of ethanol was obtained when residual fruit pulp was used as a substrate. This study has further demonstrated the feasible biotechnological conversion of agrowastes to produce ethanol using both A. niger and S. cerevisiae.

Published: March 2023

The article describes the granulometric analysis of airborne wood dust of African padauk (Pterocarpus soyauxii). Sandpaper was used under industrial relevant conditions to generate wood dust with a relatively wide particle size distribution (<63, 63, 71, 100, 200, 315, or 500 µm). This article aimed to perform a sieve analysis of the wood dust of African Padauk, characterize its morphological structure, determine certain physical properties (density, bulk density, and moisture content), and assess the effect of airborne dust particle size on minimum ignition temperatures. The 100-μm fraction was the most frequent dust particle size and represented 42.14 ± 1.049%. The ignition temperature of airborne dust was 390 °C for the 500-μm fraction and 370 °C for the 71-μm fraction.
Branch wood properties and potential utilization of this variable resource
Authors: Suansa Nurul Iman , Al-Mefarrej Hamad A.
Published: March 2023

Wood can be regarded as the single most important natural resource of the future, as it is a magnificent gift of nature. However, wood is a highly variable and complex material. Branch wood is a part of a tree that requires careful attention due to several disadvantages, making it less favorable for industrial use. This study was conducted to identify the basic properties of branch wood of Acacia gerrardii, Tamarix aphylla, and Eucalyptus camaldulensis, and to highlight its potential utilizations. Branch wood of all the examined species had several drawbacks that markedly limit its potential for commercial uses. It might not be favorable for particleboard, flakeboard, or fiberboard because of its high shrinkage. Even though all of the fibers showed suitability as a raw material for pulp and paper, the quality is low due to the high density of vessels or parenchyma proportions. However, branch wood of all examined species might be used as a blending material (papermaking and glued plates) or for light construction purposes. In considering the chemical composition of branch wood, classes of green products, such as biofuel, bioenergy, and biochar might maximize the value of branch wood. These offer numerous benefits to support human needs in the future.
Two dates from Vladimir Golenishchev’s biography
Authors: Ladynin Ivan
Published: March 2023

The article is intended to refine the dates of two important episodes in the biography of the outstanding Russian Egyptologist Vladimir Golenishchev (1856-1947), the collector of antiquities that laid the cornerstone for the Egyptian department of the Pushkin State Museum of Fine Arts, Moscow. Russian Egyptologists were sure that Golenishchev acquired the first object of his collection at the age of 14; this came to be known from the Soviet Egyptologist and Orientalist Vassiliy Struve, who had once heard it from Golenishchev himself. However, the file-cabinet of Golenishchev’s collection preserves a card for the ushebti of Qeref-en-Ptah bearing a mark that this was the first object that Golenishchev possessed given to him by the ambassador of Greece at St. Petersburg Dimitrios Buduris. As the diplomat started his mission at St. Petersburg in August 1871, he could not make this present before Golenishchev was at least 15 years old. There is also an uncertainty about the time of Golenishchev’s purchasing three important papyri: The Travel of Wenamun to Byblos, the Golenishchev Onomasticon and a literary letter (Pushkin Museum 1,1b 127). Golenishchev dated this purchase to the autumn of 1891 in his publications of 1897 and 1899, but the unpublished account of his travel to Egypt in 1890-1891 (now at the Archives of Vladimir Golenishchev at Paris) makes it perfectly clear that this took place in November and December of 1890. Symptomatically both false dates go back to Golenishchev’s statements. While the former one could be due to a real failure of memory or to the desire to bring the start of his collection closer to his childhood, the latter can be explained by an urge to disguise somehow the circumstances of his purchase by falsifying its date.
Symbiotic Efficiency and Cytokinin Activity of New Mesorhizobium cicerі Strains
Authors: Lohosha O.V. , Vorobei Yu.O. , Leonova N.O.
Published: March 2023

The efficiency of the introduction of nodule bacteria, microsymbionts of legumes in agrocenoses, largely depends on the activity of biologically active substances’ biosynthesis by diazotrophs. Seed bacterization with effective rhizobia strains capable of synthesizing exometabolites for phytostimulating activity not only promotes the formation and functioning of symbiosis but also creates the conditions for increasing plant resistance to adverse environmental conditions. The aim of the work was to research the symbiotic activity, efficiency and ability of chickpea rhizobia new strains to biosynthesize phytohormonal exometabolites of cytokinin nature. Methods. Microbiological, physiological, cytological, biochemical, and physicochemical. Results. New strains of Mesorhizobium ciceri ND-101 and Mesorhizobium ciceri ND-64 were shown to have different symbiotic activity. The efficiency of inoculation of Skarb chickpea seeds with bacterial suspension of Mesorhizobiu mciceri ND-101 was at the same level with the industrial strain of Mesorhizobium ciceri H-12. Bacterization of Mesorhizobium ciceri ND-64 increased the chickpea roots nodules by 69%, their weight by 74%, and nitrogenase activity by 73% relative to the positive control (inoculation with Mesorhizobium ciceri H-12), as well as increased chickpeas yield by 22%. It was established that Mesorhizobium ciceri ND-64 strain exhibits the highest cytokinin activity in the bioassay. Cytokinins in the total amount of 174.94 μg/g of completely dry biomass were detected in the culture medium of Mesorhizobium ciceri ND-64, which is 53% higher than that of Mesorhizobium ciceri ND-101 strain and 99% higher than that of Mesorhizobium ciceri H-12 strain. Conclusions. Mesorhizobium ciceri ND-64 strain with high nitrogen-fixing activity and symbiotic efficiency is capable to synthesize a relatively high amount of extracellular cytokinins. The high concentration of cytokinins indicates their important role in the formation and functioning of nodules, as they stimulate the proliferation of root tissues and, in this way, have a positive effect on the chickpea productivity.

Authors: Baari Muhamad Jalil
Published: March 2023

Corrosion and scale formation are crucial issues in the petroleum industry. They can inflict metal or other materials breakdown, leading to environmental pollution. Applying scale and corrosion inhibitors is a cost-effective and efficient way of controlling corrosion and scale formation in a fluid system. Much research has been conducted to obtain cheap and safe corrosion or scale inhibitors. Modified polysuccinimides (PSI) are among the organic compounds reported as effective and environmentally friendly corrosion as well as scale inhibitors. The use of various novel green corrosion and scale inhibitors from modified PSI for controlling corrosion reactions or scale formation has not been extensively reviewed. Hence, this review highlights recent studies on preparing PSI/OSI, modifying PSI, and analyzing their performance as corrosion and scale inhibitors. Adsorption study, biodegradation performance, computational quantum study, limitations, and prospects of the inhibitors are also discussed. Therefore, i this work provides an overview of novel modified PSI as effective and safe corrosion or scale inhibitors in different media, for various metals, and on a different scale.

Historically Black Colleges and Universities (HBCUs) operate and are centered within the nexus of concerted nationwide efforts to advance the participation and success of Black students within the sciences, technology, engineering, and mathematics disciplines (STEM). Through an institution-level
asset-based approach, this study aimed to further elucidate how undergraduate STEM preparation and success at HBCUs is linked to the transition into (and experiences within) graduate education. One hundred and fifty-one HBCU alumni from 37 unique HBCUs completed our HBCU Alumni Success survey. Factor analysis revealed 13 emerging components along three main touchpoints along alumni's graduate pathway: their HBCU undergraduate experiences, graduate application, and decision-making, as well as graduate school experiences. Cluster analysis further identified five unique clusters of alumni, revealing variation regarding the individual, institutional, and cultural factors that contributed to HBCU alumni's experiences within their graduate pathway. Specific attributes that characterized each unique cluster included (Cluster 1) experiencing challenges throughout their
graduate pathway, (Cluster 2) variation in the sources of motivation that influenced graduate school choice, (Cluster 3) deliberation around attending graduate school, (Cluster 4) high commitment, success, and support in pursuit of a graduate degree, and (Cluster 5) high personal agency as well as faculty and research support within engineering. Implications for practice include capitalizing on the areas of success such as the impact of faculty mentorship and research opportunities.
Feature Analysis for Motor Imagery EEG Signals with Different Classification Schemes
Authors: KAYA Esra , SARITAS Ismail
Published: March 2023

A Brain-Computer Interface (BCI) is a communication system that decodes and transfers information directly from the brain to external devices. The electroencephalogram (EEG) technique is used to measure the electrical signals corresponding to commands occurring in the brain to control functions. The signals used for control applications in BCI are called Motor Imagery (MI) EEG signals. EEG signals are noisy, so it is important to use the right methods to recognize patterns correctly. This study examined the performances of different classification schemes to train networks using Ensemble Subspace Discriminant classifier. Also, the most efficient feature space was found using Neighborhood Component Analysis. The maximum average accuracy in classifying MI signals corresponding to right-direction and left-direction was 80.4% with a subject-specific classification scheme and 250 features.

“Actores sociales y alternativas de coordinación para el desarrollo territorial” es una obra que reúne una serie de estudios sociales con un enfoque territorial, lograda gracias al esfuerzo colectivo de estudiantes y docentes de posgrado de tres instituciones académicas del Sur y Occidente de México. El libro ofrece al lector información detalladas de investigaciones empíricas que relatan las experiencias de actores locales que se interrelacionan y coordinan para confrontar diversas problemáticas que impone la  globalización capitalista; ya sea a través de mecanismos que buscan propiciar formas alternativas de desarrollo o generar vías alternativas al desarrollo para mejorar las condiciones de vida de ciertos grupos sociales, o bien para reivindicar saberes y epistemologías -del sur- que son escasamente reconocidas por la racionalidad moderna. Propone, con tales experiencias, comprender los procesos de configuración de los territorios desde una mirada que no solo observa cómo actores hegemónicos imponen instituciones, reglas y normas que rigen la vida socioeconómica y productiva, sino también cómo los actores locales, desde un ámbito cotidiano, las adaptan, resisten e incluso rechazan.
Migração juvenil e a reprodução da mão de obra em propriedades rurais familiares brasileiras
Authors: Spanevello Rosani Marisa , Moreira Sandro da Luz , Matte Alessandra , Boscardin Mariele

Na agricultura familiar, a gestão da propriedade é realizada efetivamente pelos membros da família, assim como o trabalho. A mão de obra é composta pelos gestores da propriedade (geralmente os pais) que repassam as técnicas de produção e trabalho aos filhos desde muito cedo. Diante desse cenário, o objetivo desse estudo é discutir a reprodução da mão de obra em propriedades familiares tendo como norte a sucessão geracional. A partir de revisão bibliográfica, percebe-se que a gestão das propriedades familiares é significativamente dependente da mão de obra familiar. Esta mão de obra familiar é composta especialmente pelos filhos que tendem a assumir o lugar dos pais como trabalhadores e gestores da ocupação agropecuária. A partir das referências bibliográficas analisadas conclui-se que têm ocorrido dificuldades na manutenção dos filhos de agricultores no campo por meio da sucessão geracional. Como consequência, dificuldades na renovação da mão de familiar, podendo acentuar problemas sociais relevantes no meio rural como é o caso do envelhecimento e masculinização do campo.
Patrones espaciales migratorios entre campos y ciudades y su incidencia en el futuro de los territorios rurales y agroalimentarios andinos: Reflexiones desde el caso ecuatoriano
Authors: Barragán Ochoa Fernando , Martínez Godoy Diego
Published: March 2023

Los estudios migratorios en el país se han enfocado principalmente en los flujos internacionales en detrimento de las dinámicas migratorias internas, las cuales poseen una clara incidencia en las transformaciones territoriales y en el futuro de los espacios urbanos y rurales en el Ecuador. A partir de la utilización de un enfoque de análisis territorial, este artículo propone relacionar la estructuración y dinámica de los flujos migratorios internos, tanto de entrada como de salida, con la existencia de esquemas socio productivos dinámicos, a partir del estudio de tres provincias andinas del Ecuador. El trabajo sugiere igualmente un análisis desde la prospectiva territorial para determinar los principales factores del sistema migratorio interno con capacidad de incidencia en la configuración de los futuros de los territorios rurales y agroalimentarios del país.
El uso de la cartografía social teatral con niños y niñas de Fómeque y Choachí, Colombia
Authors: Ramos Tique Daniela Alejandra , Movilla Vergara José Antonio , Rozo Álvarez Angela Lucia , Rodríguez Portillo Carla
Published: March 2023

Este artículo tiene como objetivo demostrar que el uso de la cartografía social, en conjunto con técnicas teatrales en investigaciones con niños y niñas, permite una comprensión ampliada de las representaciones sobre el territorio y las experiencias cotidianas que se desarrollan en este. Para ello, se abordan teóricamente la geografía de la infancia, las representaciones sociales y el territorio. Se propone una metodología llamada cartografía social teatral (CST) como contribución al conjunto de metodologías participativas útiles en los estudios ambientales. La CST se aplicó a niños y niñas de las escuelas rurales de las veredas Hato Viejo, Chinia, Guachavita y Mortiñal, en el municipio de Fómeque, y las veredas de La Maza, El Rosario y La Caja, en el municipio de Choachí, ubicados en Colombia. Mediante esta metodología, se identificaron los aspectos más representativos del territorio para la población infantil. También, los elementos involucrados en la construcción de sus representaciones sobre el Parque Nacional Natural Chingaza, tales como el discurso institucional de conservación de Parques Naturales de Colombia y la transmisión oral de las experiencias de sus abuelos y abuelas sobre el páramo de Chingaza, antes de la llegada de las instituciones estatales. En los discursos de los niños y las niñas participantes de la investigación resaltan la fauna, el agua y la noción abstracta de la naturaleza como elemento que se mezcla entre el paisaje, lleno de fantasía y realidad.

Abstract

This article aims to demonstrate that the use of social cartography, along with theatrical techniques in investigations with children, allows a wider understanding of the representations within the territory and the daily experiences that take place in it. The concepts of the geography of childhood, social representations and territory are theoretically addressed. The methodology of Theater Social Cartography is applied to the work with children in rural schools in the villages of Hato Viejo, Chinia, Guachavita and Mortiñal in the municipality of Fómeque, and the villages of La Maza, El Rosario and La Caja in the municipality of Choachí, located in Colombia. Through this method, the most representative aspects, according to the children of the aforementioned schools, as well as the elements involved in the construction of their representations about the Parque Nacional Natural Chingaza, such as the institutional discourse of conservation of Parques Naturales and the oral transmission of the experiences of their grandparents and grandmothers about the Park before the arrival of institutions are analyzed. Elements such as fauna, water, and the abstract notion of nature as an element that mixes between the landscape full of fantasy and reality, stand out in the speeches of the children participating in this research.
Todo empieza por lo local: autogobiernos y alternativas al extractivismo de los pueblos amazónicos de Perú
Authors: Neyra Soupplet Raquel
Published: March 2023

Los pueblos indígenas amazónicos reclaman la delimitación integral de su territorio, que incluye las zonas de caza y pesca, en respuesta a la invasión territorial por parte de las actividades extractivas. Estos pueblos han elaborado propuestas de gestión y ordenamiento territorial. Después de repasar el momento extractivista en el que se encuentra Perú, en este artículo se analizan las propuestas de alternativas registradas en el Atlas de Justicia Ambiental, con base en el parámetro “resultado del conflicto”. Se identifican las características comunes que llevaron al éxito de la resistencia, aunque sea temporal. Se profundiza en las propuestas concretas más elaboradas y avanzadas de los pueblos indígenas amazónicos en acuerdo con organismos estatales locales encargados del bosque amazónico, y en las amenazas a la construcción de las propuestas frente a la intromisión permanente de actividades legales o ilegales que atentan contra su propia existencia, con asesinatos de defensores ambientales. Se concluye con una reflexión sobre la importancia del autogobierno local como respuesta al extractivismo.
El oficio de pajareros, una práctica biocultural viva de México
Authors: Roldán-Clarà Blanca , Espejel Ileana
Published: March 2023

Los pajareros son personas que conocen, usan y manejan las aves silvestres. Su oficio, que es una tradición en México y parte del patrimonio biocultural vivo del país, está amenazado en la actualidad por distintos factores sociales, como la percepción distorsionada que se tiene de él y su criminalización. El objetivo de esta investigación es documentar por primera vez en un artículo académico sus vivencias sobre las referidas problemáticas. La metodología usada es la inmersión etnográfica, la observación participante y 60 entrevistas a pajareros de México. Los pajareros coincidieron en nombrar cinco tipos de problemas; la mayoría de las soluciones planteadas radican en la petición de ser escuchados. Para resolver esta problemática y que su voz sea parte de una valoración plural del oficio, se propone la transdisciplina como práctica democrática ambiental que los sitúe como protagonistas en la toma de decisiones en el proceso de emisión de permisos, y fomente procesos de enseñanza/aprendizaje entre todos los actores involucrados.
Evaluación del SCAE-Agua como herramienta para guiar la sostenibilidad del agua urbana
Authors: Torres Lopez Susana , Rodríguez-Labajos Beatriz
Published: March 2023

Entre los diferentes métodos analíticos que se pueden utilizar para analizar la gestión y las políticas sostenibles del agua, Naciones Unidas promueve la metodología estandarizada del Sistema de Contabilidad Ambiental y Económica para el Agua (SCAE-Agua). Si bien se ha probado a escala subnacional, su implementación en entornos urbanos está comenzando. El objetivo del artículo es evaluar hasta qué punto las herramientas disponibles dentro del SCAE-Agua pueden guiar la gestión sostenible del agua urbana. Se emplea una metodología multidimensional, preponderantemente cualitativa. Sobre la base de la información compilada del SCAE-Agua e información complementaria para aspectos sociales, el marco del SCAE-Agua fue evaluado como una herramienta para responder a los retos de sostenibilidad urbana, en las ciudades en crecimiento de América Latina. Se concluye que la implementación del SCAE-Agua en el ámbito urbano permite recopilar información sobre cantidad y calidad de los recursos hídricos, además de la economía de la ciudad. Ello es útil para organizar la información sobre los flujos y la productividad económica del agua, y para detectar presiones urbanas sobre la calidad de esta. Sin embargo, este marco pierde información necesaria para gestionar el agua como un elemento holístico entrelazado en los procesos socioambientales en las áreas urbanas. Una brecha clave identificada es la equidad del agua.

 La implementación del SCAE-Agua en una ciudad latinoamericana demostró su utilidad para recopilar información sobre cantidad y calidad de los recursos hídricos, además de la economía de la ciudad. Esto es útil para organizar la información sobre los flujos de agua y la productividad económica del agua, y para detectar presiones urbanas claves sobre la calidad del agua. Sin embargo, este marco pierde información relevante necesaria para gestionar el agua como un elemento holístico entrelazado en los procesos socioambientales en las áreas urbanas. Una brecha clave identificada es la equidad del agua.
