Published: July 2023

The use of clean energy is an important part of promoting sustainable energy development. As a clean energy source, coalbed methane, during the mining process, the position of the nozzle can influence coalbed methane extraction efficiency by affecting the cracking effect of coal. To investigate the impact of nozzles on the effect of coal fracture, a test of simulated coal by high-pressure air blasting was executed using nozzles 100 mm, 200 mm, and 250 mm from the orifice. Based on the test results and theories of fracture damage mechanics, two damage fracture models were established for the nozzles located in the middle-upper and middle-lower of the blasthole, respectively. The fracturing process and increased permeability mechanism of the coal were revealed by these two models. The results show that: when the nozzle is 100 mm from the orifice, the high-pressure air impacts the blasthole wall first, similar to a uniform expansion. Multiple longitudinal cracks are formed penetrating the coal. The permeability of the coal seam is greatly improved. When the nozzle is 200 mm and 250 mm from the orifice, the high-pressure air first impacts the bottom of the blasthole. The bottom hole angle and apex hole angle first form horizontal cracks while longitudinal cracks only appear at the same depth as the blasthole. The nozzle is 250 mm from the orifice to form a compaction zone at the bottom of the blasthole. The crack density is small and the tangential depth is shallow, which is not conducive to coalbed methane mining. The results of the research offer a theoretical framework and point of reference for the use of high-pressure air blasting technology in the extraction of coalbed methane (CBM).
Increasing Sugarcane Production Eco-Efficiency: A DEA Analysis with Different Sugarcane Varieties
Authors: Da Cruz Thiago Vizine , Machado Ricardo Luiz
Published: July 2023

The development of new sugarcane varieties affects crop production positively. However, only some studies have investigated how the use of different sugarcane varieties reacts to the impact of climate change, and how to improve sugarcane production efficiency considering the use of different sugarcane varieties in the field. This research hypothesizes that it is possible to mitigate climate change’s impact on sugarcane production and improve eco-efficiency if the proper sugarcane varieties are chosen. The main objective is to analyze the influence of different sugarcane varieties on production eco-efficiency. An econometric study unveiled the main elements affecting sugarcane production in this research. Afterward, a data envelopment analysis determined the sugarcane varieties with more efficient production. The results indicated that climate impact on production was irrelevant when controlling for different sugarcane varieties. Furthermore, it was found that through correct variety choosing, it is possible to improve harvest efficiency. The outcome of this research contributes to achieving the United Nations SDGs 1, 2, 7, 9, and 15.
A Mechanistic Study of the Impact of Digital Payments on Rural Household Development Resilience
Authors: Wu Bingbin , Wang Linping , Yao Lin
Published: July 2023

China has made advancements in the achievement of the poverty relief goal set by the 2030 Agenda for Sustainable Development of the United Nations. However, the rapidly changing socioeconomic environment and the increasingly growing complication of poverty in rural households make it necessary to enhance rural household development resilience to ensure poverty alleviation. With the rapid development of Internet technology, this paper assesses whether digital payments influence rural household development resilience. Based on it, this study takes rural China as its research area, selects samples of farmers’ household registration as its research object, uses the data recorded by China Household Finance Survey (CHFS) in 2015, 2017, and 2019, and constructs the index of “rural household development resilience” based on the family wellbeing model to empirically test the impact of rural households using mobile payments on development resilience. By considering the nonlinear dynamics of event development, this paper addresses the short-term effects of the previous exclusive examination of digital payments, providing a theoretical basis for future research on the relationship between digital payments and development resilience. The results show the following: (1) digital payments can significantly enhance rural household development resilience; (2) relaxing liquidity constraints and promoting farmer-oriented market participation are the primary mechanisms by which digital payments affect rural household development resilience, but digital payments do not have an impact on rural household development resilience by releasing credit constraints; and (3) the heterogeneity regression analysis showed that the promotion effect of digital payments on rural household development resilience is the strongest in the Western areas, at medium level in the Central areas, and the weakest in the Eastern areas. Thus, the influence of digital payments is not significant to rural household development resilience. Based on the conclusions mentioned above, this article proposes countermeasures and suggestions.
A Multi-Regional Input–Output Model to Measure the Spatial Spillover of R&D Capital
Authors: Wang Chunyun , Xing Senyu , Xu Lixiao
Published: July 2023

Reallocating innovative capital elements can improve the growth of total factor productivity and promote high-quality economic development. The multi-regional multiplier model measures the spatial spillover effects of R&D capital to trace the interregional R&D flows and explore the engines of the longer-term economic growth in China. Results show that the direct R&D intensity in different regions is all concentrated in basic research sectors supported by government funds, and decreased from coastal areas to inland areas. Second, R&D gradually flowed from China’s coastal regions to inland regions, from upstream basic research sectors to downstream infrastructure construction sectors. Third, Guangdong, Jiangsu and Beijing are the main contributors, with R&D spillover intensities reaching 1.69%, 1.40%, and 1.37%, respectively. Xinjiang, Tibet, and Hainan are the main beneficiaries, with R&D inflow intensities reaching 0.49%, 0.53%, and 0.50%, respectively. Finally, the channel of R&D spatial spillover manifests a circular distribution and contact-type and jump-type modes.

Authors: Bacuilima Evelyn , Morocho Joseline , Aguirre Juan , Coronel-Pangol Katherine , Mora Pedro
Published: July 2023

Social entrepreneurship is a topic of great development at the research level, which aims to discover, exploit and define the possibilities of increasing social wealth through activities and processes carried out with the creation and management of an innovative enterprise. From this, it has been identified that one of the main problems of social entrepreneurs in underdeveloped countries is the lack of financing, where new forms of financing have not been consolidated, as is the case with impact investment. Therefore, the objective of this research is to determine the role of impact investment in each of the Ecuadorian social enterprises under study. To this end, a qualitative research methodology of an interpretive nature was adopted through in-depth interviews with social entrepreneurs for the construction of results by means of summary tables and descriptive and graphic taxonomy. The results show that for most of the social enterprises studied, the role of impact investment is null, without this implying a lack of knowledge on the part of the social enterprises. Finally, it is necessary that policymakers take into account the need to promote sustainable development by improving social inclusion to support projects and enterprises that generate employment and opportunities for marginalized and vulnerable groups, promoting policies and measures that encourage this type of investment to generate a positive impact on the country.

Published: July 2023

Urban seismic hazards are natural disasters caused by earthquakes in urban areas, which may lead to serious casualties, the collapse of buildings, infrastructure damage, and other impacts, require huge social resources for recovery and reconstruction, and even affect the security stability and sustainable development of the area. This paper adopts the research idea of “Risk = Hazard × Exposure × Vulnerability ÷ Emergency response and recovery capability” and constructs an evaluation system containing 24 representative indicators on this basis. The CF-logistic regression model is applied in the study to calculate the seismic hazard, while the combined weight-TOPSIS model is used to assess the vulnerability of urban hazard-bearing body. Lastly, the study conducts multi-criteria seismic risk evaluation using the GIS platform. The results show that the overall seismic risk in Songyuan is moderate, with 18.66% of the medium-risk area, 37.68% of the very low risk area, 33.96% of the low-risk area, 8.47% of the high-risk area, and 1.23% of the very high-risk area. The significance of this study is to provide a scientific basis for formulating corresponding disaster prevention and mitigation measures and emergency plans, improving urban disaster prevention and emergency response capabilities, reducing urban earthquake disaster losses, and helping to achieve safe and stable urban development.

Published: July 2023

Antibody studies analyze immune responses to SARS-CoV-2 vaccination and infection, which is crucial for selecting vaccination strategies. In the KoCo-Impf study, conducted between 16 June and 16 December 2021, 6088 participants aged 18 and above from Munich were recruited to monitor antibodies, particularly in healthcare workers (HCWs) at higher risk of infection. Roche Elecsys® Anti-SARS-CoV-2 assays on dried blood spots were used to detect prior infections (anti-Nucleocapsid antibodies) and to indicate combinations of vaccinations/infections (anti-Spike antibodies). The anti-Spike seroprevalence was 94.7%, whereas, for anti-Nucleocapsid, it was only 6.9%. HCW status and contact with SARS-CoV-2-positive individuals were identified as infection risk factors, while vaccination and current smoking were associated with reduced risk. Older age correlated with higher anti-Nucleocapsid antibody levels, while vaccination and current smoking decreased the response. Vaccination alone or combined with infection led to higher anti-Spike antibody levels. Increasing time since the second vaccination, advancing age, and current smoking reduced the anti-Spike response. The cumulative number of cases in Munich affected the anti-Spike response over time but had no impact on anti-Nucleocapsid antibody development/seropositivity. Due to the significantly higher infection risk faced by HCWs and the limited number of significant risk factors, it is suggested that all HCWs require protection regardless of individual traits.
SCANellome: Analysis of the Genomic Diversity of Human and Non-Human Primate Anelloviruses from Metagenomics Data
Authors: Laubscher Florian , Kaiser Laurent , Cordey Samuel
Published: July 2023

Anelloviruses are extremely prevalent in the human population and are considered to be commensal parts of the human virome. The best-known member in humans is the Torque teno virus. Recent metagenomic next-generation sequencing investigations have helped reveal the considerable number of species and genotypes from the same genus that can be co-detected within a single individual and that this diversity increases as a function of age during the first months/years of life. As a result, to date, the bioinformatics analysis of this genetic diversity remains complex and constraining for researchers. Here, we present SCANellome, a user-friendly tool to investigate the anellome composition at the genus, species, and genotype levels of samples from metagenomics data generated by the Illumina and Nanopore platforms. SCANellome is based on an in-house up-to-date database that includes all human and non-human primate anellovirus reference sequences available on GenBank and meets the latest classification criteria established by the International Committee on Taxonomy of Viruses.

Published: July 2023

The employment of compounds obtained from natural sources to produce adsorbents and their application in the elimination of antibiotics from industrial effluents have gained significant attention because of their low production cost and sustainability. Herein, chitosan (biopolymer) and smectite (abundant clay mineral) were used for the low-cost and eco-friendly synthesis of a new type of adsorbent. A low-energy-consumption hydrothermal process was applied to the synthesis of the chitosan-derived carbon–smectite nanocomposite with cobalt (H_Co/C-S). The produced nanocomposite was characterized using elemental analysis, ICP-OES, XRPD, low-temperature N2 adsorption–desorption isotherms, FTIR analysis, and point of zero charge. H_Co/C-S (SBET = 0.73 m2 g−1, d001 = 1.40 nm, pHPZC = 5.3) was evaluated as a ciprofloxacin adsorbent in aqueous solution. Experimental data were fitted with different kinetic models and interpreted by selected adsorption isotherms. The pseudo-second-order model was found to be the most appropriate, while ciprofloxacin adsorption onto H_Co/C-S was best described by the Redlich–Peterson isotherm (R2 = 0.985). The maximum adsorption capacity of H_Co/C-S, according to the Langmuir isotherm (R2 = 0.977), was 72.3 mg g−1. Desorption and thermodynamic studies were performed. The obtained results indicated that the new hierarchically designed H_Co/C-S has promising potential to be further tested for application in real wastewater treatment.
Hydraulic Planning in Insular Urban Territories: The Case of Madeira Island—Ribeira Brava, Tabua
Authors: Lousada Sérgio , Alves Raul , Fernandes Mário , Gonçalves Leonardo
Published: July 2023

This study’s primary goal was to conduct an analysis of the flood propensity of the Tabua (Ribeira Brava) drainage basin’s main watercourse. In addition to that, this study also recommends two different methodologies in order to mitigate flood impacts, namely by dimensioning a detention basin and adjusting the riverbed roughness coefficient. Regarding the study on the flood propensity, it was necessary to resort to geomorphological data, which were obtained when characterizing the watershed; these data were crucial to determining the expected peak flow rate, according to the Gumbel distribution methodology and considering a 100-year return period, and to perform necessary tasks in the SIG ArcGIS 10.5 software. Lastly, the drainage capacity of this drainage basin’s river mouth was also analyzed in order to conclude whether it would have the capacity to drain the total volume of rainwater if an extreme flood event were to happen. Indeed, the main results show that this watershed’s river mouth does not have the necessary drainage capacity to cope with an extreme event for the return period that was considered. As a consequence, the two aforementioned mitigation measures were developed considering the Tabua (Ribeira Brava) drainage basin’s specific features. The size of the detention basin was estimated through the Dutch method and the simplified triangular hydrograph method, while the adjustment of the roughness coefficient was considered a valid solution to enhance the drainage capacity of this river mouth.
Écrire les sons. Création des premières notations musicales
Authors: Rankin Susan
Published: July 2023

Quand un mode de notation musicale totalement nouveau – et qui s’avérera finalement à l’origine des notations occidentales modernes – fut inventé à la fin du viiie s. ou au début du ixe s. dans l’Europe carolingienne, comment fut-il conçu ? Quelles informations cette notation était-elle censée enregistrer par écrit ? et avec quels effets sur la pratique du chant ? Partant d’un fragment annoté datant des environs de 900, cet article s’attache à l’étude des notations musicales du ixe s. en considérant ce à quoi elles semblaient servir et ce à quoi elles ne servaient pas. La façon dont ces notations transcrivaient certains sons et non d’autres, ainsi que la variabilité de ce qu’elles transcrivaient, peuvent ainsi être expliquées d’une manière plus satisfaisante comme l’aboutissement d’un modèle plus contemporain – une interaction entre la mémoire et la lecture.
La vue des autres. L’ekphrasis au risque de la littérature médiolatine
Authors: Debiais Vincent
Published: July 2023

La description littéraire des œuvres d’art doit être rapprochée de l’ekphrasis des textes antiques, grecs puis romains. Très développée dans la poésie de langue grecque, moins nettement dans les textes de langue latine, l’ekphrasis possède une définition large (la description développée d’un objet, quel qu’il soit) et une définition restreinte (la description animée et imagée d’une œuvre d’art, réelle ou fictive). La description des œuvres d’art concerne autant le contenu des œuvres que la réflexion sur la notion d’art elle-même. Il pourrait sembler contreproductif de vouloir ainsi approcher la dimension sensorielle de l’art médiéval à travers le prisme du texte ; or, à la lecture de cette littérature foisonnante, plus ou moins bien connue, il apparaît que ce n’est pas tant l’œuvre d’art qui est au cœur de l’écriture, que l’expérience de l’art. Cette contribution a deux objectifs. Le premier, de nature théorique, analyse l’ekphrasis dans la réalité littéraire et théologique du Moyen Âge. La seconde partie voit ces réalités théoriques mises à l’épreuve des objets d’art. Dans un dialogue entre l’écrit et le visuel, quelques pistes quant à la dimension sensorielle des expériences littéraires de l’art seront posées, principalement à l’époque carolingienne, pour essayer de définir plus précisément ce que l’on entend par ekphrasis.
Isaac de l’Étoile : les cinq sens et la conversion du sens
Authors: Trottmann Christian
Published: July 2023

Nous trouvons chez Isaac de l’Étoile un enseignement original sur les cinq sens qui figure dans sa Lettre sur l’âme et recoupe sa théorie des facultés de connaissance développée au sermon IV. Encore les cinq sens se situent-ils ici en bas d’une échelle qui les dépasse par l’imagination, la raison, l’intellect et l’intelligence. Toutefois, les correspondances d’une symbolique cosmique des éléments avec ces cinq facultés rétablissent les sens comme la vision associée à l’élément igné ou l’audition véhiculée par l’air subtil, au cœur d’un mouvement de conversion du sensus entendu comme l’ensemble des facultés cognitives. Il culmine avec la prosternation des facultés supérieures : raison, intellect et intelligence, comme les trois disciples présents lors de la Transfiguration. Se produit alors une sorte d’in- version des sens où l’audition dans la foi de la voix du Père prend le pas sur la vision de la gloire du Fils dans la contemplation du mystère trinitaire.
Le philosophe et le volcan. La mémoire des savants de l’Antiquité dans la Sicile musulmane
Authors: Vanoli Alessandro
Published: July 2023

Partant de la mention dans le Murūğ al-ḏahab de l’historien al-Mas‘ūdī du tombeau du philosophe grec Porphyre dans l’Etna, le présent article se propose d’enquêter sur certaines modalités de la transmission d’éléments de la culture antique dans les traditions arabo-musulmanes sur la Sicile. Dans les écrits des géographes arabes concernant l’île volcanique, la mort de plusieurs philosophes ou savants de l’Antiquité se trouve associée à l’Etna de manière anecdotique, mais réitérée, et sans que des liens textuels puissent clairement être établis. Le parcours des textes grecs et latins, antiques et médiévaux, relatifs à ces auteurs classiques, mais aussi leur réception dans le monde arabo-musulman laissent transparaître le cheminement complexe d’une tradition mémorielle protéiforme associant les descriptions de la Sicile à la mort des philosophes de l’Antiquité.
Comment christianiser un ours ? Le mois de février du calendrier du portail Saint-Ursin de Bourges (premier quart du XIIe siècle)
Authors: Le Luel Nathalie
Published: July 2023

Le calendrier sculpté au registre inférieur du tympan du portail de l’ancienne collégiale Saint-Ursin à Bourges débute par le mois de février. Comment expliquer une telle singularité iconographique dans un cycle des mois roman ? Rejetant l’idée d’une composition fortuite du calendrier et invalidant les correspondances calendaires liturgiques, l’étude tente de répondre à cette question en croisant les données historiques, archéologiques et anthropologiques. La clé de lecture de cette particularité iconographique semble être l’ours, qui fut pendant longtemps le roi des animaux dans l’Occident septentrional, avant que l’Église ne le détrône au profit du lion. Sa place dans l’imaginaire des hommes du Moyen Âge – notamment dans le Berry – est probablement à l’origine de la mise en place d’une habile manipulation hagiographique ayant conduit à l’invention d’une stratégie visuelle de christianisation.
Refonder ou revivifier l’islam. Les stratégies d’écriture d’Abū Ḥāmid al-Ġazālī (m. 505/1111)
Authors: Pisani Emmanuel
Published: July 2023

L’islam est traversé à la fin du XIe siècle par une recrudescence du takfīr qui consiste à exclure, au nom d’une infidélité à l’orthodoxie ou à l’orthopraxie. Dans ce contexte, le vizir Niẓẓām al-Mulk a fondé de nouvelles écoles de théologie, les niẓāmiyyāt, et a nommé à Nīšābūr le jeune Abū Ḥāmid al-Ġazālī comme directeur. Mais comment reconstruire une synthèse consensuelle, intégratrice de courants s’auto-excluant, sans encourir le risque d’être taxé à son tour d’infidélité (takfīr) ? L’article montre que face à ce défi, al-Ġazālī déploie des stratégies d’écriture. Ainsi, il revient aux sources et à l’étymologie des sciences islamiques, il neutralise par la spiritualité la réalité du kufr, il adapte son langage théologique et laisse entrevoir un enseignement caché qui invite à lire et à relire le maître, par le biais d’une lecture proleptique permettant un déplacement progressif tout en se prémunissant de l’accusation d’infidélité.

Knowledge-informed deep learning for hydrological model calibration: an application to Coal Creek Watershed in Colorado
Authors: Jiang Peishi , Shuai Pin , Sun Alexander , Mudunuru Maruti K. , Chen Xingyuan
Published: July 2023

Abstract. Deep learning (DL)-assisted inverse mapping has shown promise in hydrological model calibration by directly estimating parameters from observations. However, the increasing computational demand for running the state-of-the-art hydrological model limits sufficient ensemble runs for its calibration. In this work, we present a novel knowledge-informed deep learning method that can efficiently conduct the calibration using a few hundred realizations. The method involves two steps. First, we determine decisive model parameters from a complete parameter set based on the mutual information (MI) between model responses and each parameter computed by a limited number of realizations (∼50). Second, we perform more ensemble runs (e.g., several hundred) to generate the training sets for the inverse mapping, which selects informative model responses for estimating each parameter using MI-based parameter sensitivity. We applied this new DL-based method to calibrate a process-based integrated hydrological model, the Advanced Terrestrial Simulator (ATS), at Coal Creek Watershed, CO.
The calibration is performed against observed stream discharge (Q) and remotely sensed evapotranspiration (ET) from the water year 2017 to 2019.
Preliminary MI analysis on 50 realizations resulted in a down-selection of 7 out of 14 ATS model parameters. Then, we performed a complete MI analysis on 396 realizations and constructed the inverse mapping from informative responses to each of the selected parameters using a deep neural network. Compared with calibration using observations covering all time steps, the new inverse mapping improves parameter estimations, thus enhancing the performance of ATS forward model runs. The Nash–Sutcliffe efficiency (NSE) of streamflow predictions increases from 0.53 to 0.8 when calibrating against Q alone. Using ET observations, on the other hand, does not show much improvement on the performance of ATS modeling mainly due to both the uncertainty of the remotely sensed product and the insufficient coverage of the model ET ensemble in capturing the observation. By using observed Q only, we further performed a multiyear analysis and show that Q is best simulated (NSE > 0.8) by including in the calibration the dry-year flow dynamics that show more sensitivity to subsurface characteristics than the other wet years. Moreover, when continuing the forward runs till the end of 2021, the calibrated models show similar simulation performances during this evaluation period as the calibration period, demonstrating the ability of the estimated parameters in capturing climate sensitivity. Our success highlights the importance of leveraging data-driven knowledge in DL-assisted hydrological model calibration.
The role of atmospheric rivers in the distribution of heavy precipitation events over North America
Authors: Vallejo-Bernal Sara M. , Wolf Frederik , Boers Niklas , Traxl Dominik , Marwan Norbert , Kurths Jürgen
Published: July 2023

Abstract. Atmospheric rivers (ARs) are filaments of extensive water vapor transport in the lower troposphere that play a crucial role in the distribution of freshwater but can also cause natural and economic damage by facilitating heavy precipitation. Here, we investigate the large-scale spatiotemporal synchronization patterns of heavy precipitation events (HPEs) over the western coast and the continental regions of North America (NA), during the period from 1979 to 2018. In particular, we use event synchronization and a complex network approach incorporating varying delays to examine the temporal evolution of spatial patterns of HPEs in the aftermath of land-falling ARs. For that, we employ the SIO-R1 catalog of ARs that landfall on the western coast of NA, ranked in terms of intensity and persistence on an AR-strength scale which varies from level AR1 to AR5, along with daily precipitation estimates from ERA5 with a 0.25∘ spatial resolution. Our analysis reveals a cascade of synchronized HPEs, triggered by ARs of level AR3 or higher. On the first 3 d after an AR makes landfall, HPEs mostly occur and synchronize along the western coast of NA. In the subsequent days, moisture can be transported to central and eastern Canada and cause synchronized but delayed HPEs there. Furthermore, we confirm the robustness of our findings with an additional AR catalog based on a different AR detection method. Finally, analyzing the anomalies of integrated water vapor transport, geopotential height, upper-level meridional wind, and precipitation, we find atmospheric circulation patterns that are consistent with the spatiotemporal evolution of the synchronized HPEs. Revealing the role of ARs in the precipitation patterns over NA will lead to a better understanding of inland HPEs and the effects that changing climate dynamics will have on precipitation occurrence and consequent impacts in the context of a warming atmosphere.

Narrativa identitaria y patrimonio cultural en la Argentina. El caso de los restos de la Chacra de Lanús
Authors: García Analía
Published: July 2023

El municipio de Lanús lleva su nombre en honor a una familia que representaba la identidad moderna Argentina y que por lo tanto desde la óptica política ha sido crucial para el crecimiento del pueblo. En función de ello, varios lugares han sido considerados patrimonio además de otorgar al partido dicha asignación como forma de conmemoración. Sin embargo, los restos de su chacra se encuentran desprotegidos y están a la venta. A partir del análisis de un conjunto de narrativas, junto con el estudio de las declaratorias patrimoniales y conmemorativas asociadas a la familia, en los contextos políticos bajo los cuales estas han sido elaboradas, se busca reflexionar sobre las nociones de patrimonio e identidad. Se concluye que ambas categorías son dinámicas, y que el patrimonio debe dar cuenta de múltiples apropiaciones identitarias.
Identidade nacional: as visões do povo brasileiro
Authors: Allegretti Fernanda Espindola , Zamin Iara Sabina , De Oliveira Vania Maria Abreu , Garces Solange Beatriz Billig
Published: July 2023

Este trabalho tem como objetivo compreender os fenômenos da identidade em território brasileiro, visto que o Brasil é um país fundado a partir da miscigenação. O país carrega consigo o estereótipo de acolhedor, sem preconceitos e povoado por sujeitos divertidos e de grande coração. Contudo, o que vemos é uma dificuldade em aceitar a própria história, colocando-se muitas vezes em uma complicada gama de mitos e representações falhas, onde o complexo de vira-lata acomete a população. Devido à dificuldade em identificar-se com a história do país e enxergar a realidade de uma forma não anuviada, o brasileiro também encontra dificuldades em enfrentar a realidade da população, na qual educação, política e sociedade parecem não conviverem em harmonia. E, principalmente, percebe-se a negação de uma parcela populacional em aceitar que o país abriga uma grande quantia de pessoas que necessitam de políticas sociais nas múltiplas esferas, para que possam minimamente buscar uma parcela de equidade, o que acumula mais este preconceito em relação às camadas mais necessitadas da população.
Instructor Emotional Support, Academic Resiliency, and School Engagement in an Online Learning Setting during Covid-19 Pandemic
Authors: Lobo Joseph
Published: July 2023

In recent years, numerous published scholarly works have examined the association between academic resilience and school engagement, as well as the function of emotional support in bolstering the relationship between the two. However, these investigations have only been undertaken at the elementary and secondary levels. Therefore, it can be concluded that there are only a few studies that were conducted in the context of Higher Education, especially in the Philippines. In this regard, this study aimed to evaluate the relationship between academic resilience (ARS) and school engagement (SE) via teacher-emotional support (TES). Using data from 910 students and Partial Least Square-Structural Equation Modeling (PLS-SEM), it was unraveled that (1) ARS positively affects SE, (2) ARS leverages TES, (3) TES affects SE, and (4) TES partially mediated the association between students' ARS and SE. According to the findings, instructors' emotional support promotes college students' resilience and engagement. The study underlined the need of strengthening personal and contextual resources to support student well-being in an online class setting.
Το προφίλ αθλητικού τουρίστα στην Κύπρο και η προοπτική ανάπτυξης του αθλητικού τουρισμού
Authors: Τύμβιου Ελένη
Published: July 2023

Ο τουρισμός είναι μία από τις μεγαλύτερες βιομηχανίες στην παγκόσμια οικονομία. Όλο και περισσότερα κράτη με την πάροδο των χρόνων η οικονομία τους βασίζεται στον τουρισμό. Η Κύπρος δεν μπορούσε να απέχει από αυτό αφού, η γεωγραφική της θέση, το μεσογειακό της κλίμα οδήγησαν τον νησί από το 1960 σε ένα από τα κυριότερα τουριστικά κέντρα της Μεσογείου, μετά από μια ραγδαία και συνεχή ανάπτυξη. Με βάση τη Στρατηγική Τουρισμού μέχρι το 2010 δίνεται ιδιαίτερη έμφαση στον εναλλακτικό τουρισμό, όπως είναι και ο αθλητικός τουρισμός. O σκοπός της παρούσας έρευνα ήταν να γίνει η καταγραφή του προφίλ, η διερεύνηση των τουριστικών συμπεριφορών αλλά και των κύριων ανθρώπινων αναγκών των αθλητικών τουριστών που επισκέπτονται την Κύπρο κυρίως για να συμμετέχουν σε κάποιο αθλητικό γεγονός ή δραστηριότητα, ή κάποια προετοιμασία, όπως επίσης και τι δραστηριότητες προτιμούν κατά τη διάρκεια των διακοπών τους. Το δείγμα της έρευνα αποτέλεσαν 779 αθλητικοί τουρίστες. Χρησιμοποιήθηκε το ερωτηματολόγιο TRPS των Gibson & Yiannakis (2002) το οποίο μεταφράστηκε στα ελληνικά, γερμανικά, γαλλικά και ρώσσικα από τους Υφαντίδου, Κώστα & Μιχαλοπούλου (2008). Για την υλοποίηση της έρευνας τα ερωτηματολόγια απαντήθηκαν πριν η μετά από τον αγώνα ή την προπόνηση. Για την ανάλυση των δεδομένων έγινε περιγραφική ανάλυση, τεστ αξιοπιστίας, 2 way Anova και παραγοντική ανάλυση κύριων συνιστωσών.

Abstract. Sunari AAAAS, Supartha IW, Susila IW, Utama IWEK, Yasa IWS, Yudha IKW. 2023. Short Communication: Feeding trial, biological, and demographic parameters of Spodoptera frugiperda (Lepidoptera: Noctuidae) on several Graminae species (laboratory trial scale). Biodiversitas 24: 3325-3331. The fall armyworm Spodoptera frugiperda J.E Smith is a new pest that has entered Indonesia. The ability of the S. frugiperda pest adaptation to several types of graminae plants is important to determine the distribution of potential hosts in the field. The adaptability of S. frugiperda was observed from two parameters, namely biology, and demography, which were tested on three plant types of the Graminae family consisting of hybrida variety corn, Jatiluwih local rice, and sorghum. This research was conducted from May to November 2022 at the Integrated Pest and Disease Management Laboratory (IPMLab), Faculty of Agriculture, Udayana University. The observation was made on several bionomic and demographic parameters. Demographic parameters were determined by observing the gross reproduction rate (GRR), net reproductive rate (R0), intrinsic rate of increase (r), generation time (T), doubling time (DT), and observing the fecundity rate of S. frugiperda. The results showed that S. frugiperda biology was best in hybrid corn plants with a short duration of larval life. The survival chances were obtained from daily observations of S. frugiperda, which decreased on day 32 on hybrid corn and sorghum plants. On the other hand, on Jatiluwih local rice plants, imago's survival chance started to decrease at 34 days old. In observing demographic parameters, lower R0 and r values and higher T and DT values ??indicate that hybrid corn plants are the best for S. frugiperda to grow and develop.

Abstract. Pitimol N, Srikosamatara S. 2023. Population ecology and genetic study of gaur (Bos gaurus) in a small protected area in Thailand. Biodiversitas 24: 3369-3377. Gaur population in Khao Phaeng Ma (KPM) restored forest increased from 6 individuals in 1995 to 1996 in 2006 and more afterward. Data on population sizes, distribution and genetic status are needed for effective management. The aim of this study was to obtain data on gaur population size, structure and broad distribution, and on gaur genetic diversity in KPM. For a one-year period from 2014-2015, data were collected in three areas on gaur number, group size, sex, and age using direct observation. Genetic diversity was examined at 15 cross-species microsatellite loci. The total number of gaurs was at least 184, with these individuals being highly concentrated on the western side of the area. The average group size was 13.15±0.98 (n=356). The proportion of adult males to adult females, juveniles, and calves was 35:100:51:65. From the 10 samples (4 tissue, 6 fecal), the number of alleles per locus ranged from 2 to 6 (average 4.07). The expected and observed heterozygosity were 0.594 and 0.649, respectively. The gaur population is increasing and distributes more at the forest edge. Genetic diversity was lower than gaur populations in Vietnam and India. Habitat management should be done to minimize human-gaur conflicts and increase gene flow between populations.

Published: July 2023

The residues of fruticulture of fruits such as acerola, guava, passion fruit, and mango can be efficiently used to produce enzymes by solid-state fermentation. In this work, we used these residues and the filamentous fungus Aspergillus niger ATCC 1004 to obtain carboxymethyl cellulase (CMCase). The preservation of enzyme activity is fundamental for providing commercial enzymes with a good price and high enzyme activity. Three substances (sodium chloride, sodium benzoate, and monosodium phosphate) were tested as enzyme activity preservatives; a simplex-centroid mixture design was applied to obtain the best concentrations of these substances. The effect of preservatives on the activity of the CMCase enzyme was tested for 72 hours by incubating the enzyme with the salts of sodium chloride, monosodium phosphate, and sodium benzoate at various concentrations, in citrate-phosphate buffer pH 5.0 at 50 mM, at a temperature of 50°C. The results showed that the mixture that produced the optimum response was composed of 42% sodium chloride, 38% sodium benzoate, and 20% monosodium phosphate. Then, the substances studied shows that are good option to preserve the CMCase enzyme produced by the fungus Aspergillus niger ATCC 1004.

Published: July 2023

Background. Comorbidity profiles are a common subject of research in patients with asthma-COPD (chronic obstructive pulmonary disease) overlap (ACO), but in case of concurrent type 2 diabetes mellitus (T2DM), there is a lack of targeted research on the quality of life, clinical course, and lung function. The aim of the study was to clarify the clinical features of asthma-COPD overlap in combination with T2DM. Materials and methods. Sixty-nine patients were examined: 24 with ACO and T2DM (group 1), 21 with asthma and T2DM (group 2), and 24 with COPD and T2DM (group 3). A diagnosis of ACO was made according to GINA and GOLD 2017 guidelines. Quality of life was assessed using the CAT, ACQ, and SGRQ, and the severity of dyspnea was assessed using the mMRC scale, disease severity and prognosis using the BODE index. Spirometry with bronchodilation test, 6-minute walk test, and bioimpedance analysis were performed. Results. Patients in the main group had a higher total SGRQ score than those in group 3 (by 33 %, p = 0.001). Higher ACQ and total SGRQ scores indicate a trend toward worse asthma control and lower quality of life in patients with ACO and T2DM compared to the asthma + T2DM group (p = 0.056 and p = 0.054, respectively). Body mass index was higher than in patients with COPD and T2DM (by 16.3 %, p = 0.001). Higher serum glucose levels were found in patients with ACO and T2DM than in those with COPD and T2DM (by 18.3 %, p = 0.028). The FEV1 in the ACO and T2DM group was lower than in the asthma + T2DM group (by 18.7 %, p = 0.027), and the SVC was lower by 33 % (p = 0.021). There was a tendency to a lower result in the 6-minute walk test in the main group compared to patients from group 3 (p = 0.0548), and a higher frequency of exacerbations per year compared to groups 2 (p = 0.08) and 3 (p = 0.06). Conclusions. Patients with asthma-COPD overlap and concurrent type 2 diabetes mellitus have worse quality of life, lower FEV1 and SVC, submaximal exercise tolerance, higher fasting glucose levels, and a tendency towards increased exacerbation frequency.

Objetivo: descrever o perfil das ações judiciais quanto ao fornecimento de medicamentos no município de Ponta Grossa, Paraná, entre 2019 a 2021. Metodologia: Utilizou-se o método descritivo-exploratório e retrospectivo, de abordagem quantitativa. Foram analisados 89 processos, sendo grande parte dos autores do sexo feminino (57,3%), com predomínio de assistência jurídica pública por meio do Ministério Público (69,7%) e com prescrições do serviço público (96,6%). Resultados: Observou-se que 93,3% das solicitações não constavam na Relação Nacional de Medicamentos Essenciais. Ademais, verificou-se maior demanda do medicamento Avastin (31,5). As doenças que mais acometeram a parte autora foram retinopatia diabética (42,7%; n=38) e doença pulmonar obstrutiva crônica (24,7%). Destaca-se queno período da coleta de dados, 79,8% dos processos encontravam-se finalizados. Osvalores gastoscom a judicialização de medicamentos variaram de R$ 407,94 a R$ 47.220,00. Considerações: Haja vistao número não exorbitante de ações judiciais, é possível que existam estratégias municipais efetivas, ou a ausência de Defensoria Pública no atendimento as demandas de saúde, pode ter tornado fator inibidor de acesso à justiça. Outro ponto quanto a delimitação no acesso, são os requisitos cumulativos firmados na tese pelo STF, quanto a concessão de medicamentos não previstos nas listas de dispensação do SUS. Conclui-se que há necessidade de aprimorar o diálogo entre o judiciário e o setor de saúde por meio dos seus gestores, bem como a realização de mais estudos parasubsidiar um mapeamento, planejamento, descrição de gastos com a judicialização, aquisição de medicamentos e incorporação de novas tecnologias.
