Designing platforms for digital object-based learning
Authors: McKenzie Jessica , Rampe Michael
Published: November 2024

Over the last decade, object-based learning programs have become a staple of museum collections. These programs encourage and allow patrons to engage with a series of curated objects, offering educational experiences through tactile exploration. Naturally, they are focused on having their audience engage with the physical objects themselves (Chatterjee & Hannan 2016). Applying museological practice and object-based learning in the digital context requires not just presenting digital replica of physical objects, but scaffolding their presentation and platform with purpose, intent, and understanding of the strengths and pitfalls of digital delivery (Beetham & Sharpe 2013; De Kluis, Romp, & Land-Zandstra 2024). As such, digital object-based learning platforms and programs purposefully designed for remote learning and online delivery fill a unique niche in the higher education space and are beginning to come into their own.
At Macquarie University, objectbasedlearning.com (an initiative of the Faculty of Arts and stewarded by its Learning Design and Production team) was relaunched in late 2023 following an extensive redesign, with learning designers, academics, and students now working together to provide new remote learning opportunities and experiences for the classroom. This presentation introduces the audience to the refurbished website, explains the ethos behind its redesign with an eye to evolving learning spaces and remote learning, and explores the site’s current and future applications and projects as a case study for designing digital object-based learning.
The site was designed with future utility and outreach at its core, offering flexibility in how it presents and categorizes digital objects, and a site layout which reflects the needs of its target audience – schoolteachers. The NSW Stages 5 and 6 Curriculum informs the website’s design, determining how objects are grouped, how users navigate the site, and what information and metadata is prioritized, developed, and displayed. Since its relaunch, the website has been utilized in schools and faculties in NSW to deliver object-based learning experiences and classes. While it is too early to publish on outcomes of the project, early feedback has been positive, and new teaching initiatives have developed around the platform. In 2024, student interns at Macquarie were challenged to develop educational materials, lessons, and workshops which took advantage of the potential of technology-enabled object-based learning. These artefacts were designed to give students a unique object-based learning experience, removing the boundaries of physical distance, financial constraints, and fragility of objects. Moreover, student interns involved in the photogrammetric scanning of objects for the website were themselves enjoying an object-based learning experience, engaging with their materiality and learning how best to present the object in a digital environment.
Flipped Learning with Generative Artificial Intelligence
Authors: Bui Nguyen
Published: November 2024

This study explores the complex process of integrating generative artificial intelligence (GenAI) into a flipped classroom. Employing Clandinin and Connelly’s (2000) narrative inquiry framework, the study collected data from class observations and semi-structured interviews with a lecturer and six English-majored undergraduates before, during, and at the end of a 15-week British Literature course. Bhattacharya’s (2017) inductive analysis model was used to inform the thematic narrative sub-approach. The findings revealed both challenges and benefits associated with using GenAI for flipped learning while highlighting its impact on students’ self-regulated learning and teacher self-efficacy.
This presentation retells stories from the participants’ lived experiences in a GenAI-enabled and flipped classroom. Exemplary learning resources are showcased to demonstrate how GenAI tools can effectively and efficiently facilitate flipped learning. The insights gained from this study contribute to a deeper understanding of the potential of GenAI in transforming educational practices and enhancing the flipped learning experience.
Recent advances in the characterization of genetically defined neurons that regulate internal‐state‐dependent taste modification in mice
Authors: Nakajima Ken‐ichiro
Published: November 2024

The gustatory system plays an important role in evaluating food quality in animals and humans. While some tastes are intrinsically appetitive, such as sweet, which is elicited from high‐calorie nutrients, the other tastes, such as sour and bitter, are aversive and elicited by toxic substances. In mice, taste signals are relayed by multiple regions of the brain, including the nucleus of the solitary tract, and the parabrachial nucleus (PBN) of the pons, before reaching the gustatory cortex via the gustatory thalamus. Recent advances in taste research using mice expressing Cre recombinase in specific neuronal populations, together with chemogenetic/optogenetic tools, have enabled us to identify genetically defined neurons involved in taste transduction pathways across several areas of the brain. While gustatory pathways play a fundamental role in taste transduction, taste preferences are not always stable, but rather vary depending on internal states. This review summarizes recent progress in research on neural circuits that modify the taste information depending on internal states in mice.

Authors: Louhaichi Mounir , Al-koor Basel Abdulla Salem , Gamoun Mouldi , Abdurahman Anwar Adam Abdulgader , Hassan Sawsan
Published: November 2024

Plant diversity in southern Yemen is crucial for maintaining rangeland ecosystem functions. This diversity contributes to the resilience of local pastoral communities, by providing essential forage and resources. However, high stocking density has led to the overuse of palatable species, resulting in increased competition for forage. This study evaluates the nutritional value of 25 indigenous forage species from the natural rangelands of Lahij Governorate. Significant variations were observed among the Forage species, with moisture content ranging from 4 to 39.6%, crude protein from 5.5 to 21.4%, non-fiber carbohydrates from 31.8 to 66.4%, crude fiber from 8.3 to 42.65%, and ash content from 9.2 to 34.6%. Clitoria ternatea, Lycium barbarum, Senegalia mellifera, Vigna sinensis, Albizia lebbeck, and Acacia trees with crude protein content higher than 16% showed substantial potential as livestock feed due to their favorable proximate compositions. Incorporating these high-potential species into regular livestock diets could significantly enhance the sustainability and productivity of pastoral systems in southern Yemen, addressing the current fodder shortage.

Authors: Qureshi Almas , Rahman Rais ur , Shamsi Yasmeen
Published: November 2024

Objectives

Urinary tract infection (UTI) is one of the most frequent reasons for prescribing antibiotics. Escherichia coli implicated in 75–90 % cases of UTI is becoming increasingly resistant to antibiotics. Finding alternative therapeutic agent for this infection is critical, for which herbal drugs may be an option. In Unani medicine, urinary tract infection (Ṭa’diya Majra-i-Bawl) is treated with herbal drugs possessing Da’fe Ufoonat (antiseptic), Muhallilat (anti-inflammatory) and Mudirrat (diuretic) properties. Polyherbal formulations of such drugs are expected to be beneficial in treating Escherichia coli infection. The aim of the study was to assess the efficacy and safety of a Unani polyherbal formulation aimed to develop a safe and efficacious drug for the treatment of urinary tract infection (Ṭa’diya Majra-i-Bawl) caused by Escherichia coli.

Methods

This open-label, single armed clinical study was conducted on patients with clinical signs and symptoms of UTI and positive urine culture for E. coli. Patients were treated with the polyherbal formulation consisting of 50 % hydro-alcoholic extracts of Khar Khasak (Tribulus terrestris), Bhui Amla (Phyllanthus niruri), Kabab Cheeni (Piper cubeba), Beekh -i-Kasni (Cichorium intybus), Beekh-i-Karafs (Apium graveolens), Asl-us-Soos (Glycyrrhiza glabra), and Giloy (Tinospora cordifolia) in a dose of one capsule (500 mg) thrice a day orally with plain water for 42 days.

Results

Maximum (83 %) urine cultures turned out negative for E. coli after the completion of therapy.

Conclusions

Polyherbal Unani formulation was found to be very effective for the treatment of Urinary tract infection. Clinical and microbiological cure was achieved in maximum number of patients and drug was very well tolerated without any adverse/side effect.

Published: November 2024

In this study, the soil CO2 emission was analysed at the level II ICP Forests monitoring plot in Serbia in the pedunculate oak forest. Two plots of pedunculate oak (Quercus robur L.) were selected for this study. The main question was to determine the differences in the impact of management (human impact) on CO2 emission. Different time periods were compared to identify the main factors affecting soil CO2 emission. Sampling was done by chambers. During the study period, climate indicators were quite different. A strong positive correlation between the soil temperature and soil CO2 emission, as well as a strong negative correlation between the soil moisture and soil CO2 emission, was found in the spring aspect (Plot). In other cases, a moderate to weak correlation was found. Multiple linear regressions showed that CO2 emission from soil was primarily controlled by soil moisture. Increasing soil water content had a positive effect on soil respiration (except in spring). The effect of soil temperature appeared in the multiple regressions as a secondary factor during the period studied, and an increase in temperature resulted in a decrease in soil respiration (except in spring).
Eine auf Deutschland orientierte bewaffnete Neutralität
Authors: Kopõtin Igor
Published: November 2024

Der Aufsatz untersucht die Ursachen, Formen und Akteure der militärpolitischen Zusammenarbeit zwischen Deutschland und Estland in den 1930er Jahren. Auf estnischer Seite ergab sich das Interesse an einer Kooperation aus dem Umstand, dass die estnische Führung die Sowjetunion als einzigen wahrscheinlichen Feind in einem zukünftigen Krieg betrachtete. Auf deutscher Seite sollten die Beziehungen die Neutralität des baltischen Landes sichern und seine Bereitschaft zur Abwehr gegenüber der Sowjetunion stärken. Es war im Interesse Deutschlands, dass Estland sowie andere Randstaaten keine sowjetischen Truppen durch ihr Territorium lassen würden. Darüber hinaus war das deutsche Interesse an Estland durch dessen geografische Lage – an der Ostsee und nahe Leningrad gelegen – motiviert. Dies ermöglichte es dem deutschen militärischen Nachrichtendienst, Estland als Stützpunkt gegen die Sowjetunion zu nutzen.

Authors: Martín Núñez Javier , Heredia Ciuró Alejandro , Calvache Mateo Andrés , Ortiz Rubio Araceli , Valenza Peña Geraldine , Raya Benítez Julia , Valenza Marie Carmen
Published: November 2024

Objectives

Cancer-related fatigue is prevalent in prostate cancer patients. This symptom can negatively affect patients’ performance and emotional well-being, but there is no consensus on the best therapeutic approach. Despite the growing evidence on the management of fatigue with exercise, there are recognised limitations in its use when considering the different cancer patients. Specifically, prostate cancer patients under androgen deprivation therapy present several contributors to fatigue, emotional distress, inactivity, and deconditioning. The aim of this research was to describe the current literature on the effects of supervised combined aerobic and resistance training on fatigue in patients under androgen deprivation therapy.

Methods

We conducted a literature search in PubMed, Scopus, and Web of Science. The GRADE and the Cochrane tools were used to assess the quality and risk of bias of the selected studies. Only randomised controlled trials in which combined aerobic and resistance training was used with prostate cancer patients under androgen deprivation therapy were included. A cancer-related fatigue meta-analysis was performed.

Results

Nine studies with a low risk of bias were included in the review. Regarding cancer-related fatigue, significant results that cannot be attributed to chance were found in favour of combined exercise (MD=0.71; 95 %; CI=0.05, 1.37; p=0.03; I2=91 %). The GRADE system showed a moderate recommendation.

Conclusions

Supervised combined aerobic and resistance training was proven to significantly improve fatigue in patients with prostate cancer under androgen deprivation therapy. These findings could provide clinicians with more information on the management of cancer patients under androgen deprivation therapy.
Real-world analysis of the incidence and risk factors of pneumonitis in non-small cell lung cancer patients treated with combined thoracic radiotherapy and immunotherapy
Authors: Liu Yuanxin , Yang Xue , Wang Yan , Zhou Laiyan , Xue Jianxin
Published: November 2024

Objectives

Combining radiotherapy with immune checkpoint inhibitor (ICI) treatment has emerged as an important therapeutic regimen. However, this combined treatment may increase the risk of pneumonitis. The aim of this study is to analyze the incidence and risk factors for pneumonitis in non-small cell lung cancer (NSCLC) patients receiving combined thoracic radiotherapy and ICI (RT + ICI) treatment in the real-world clinical setting, offering a reference and guidance for clinical physicians.

Methods

This study identified 447 patients with pathologically confirmed NSCLC at West China Hospital of Sichuan University from 2016 to 2021. Clinical characteristics, treatment regimens, immune-related adverse events (irAEs), and hematological data were collected and analyzed.

Results

Patients receiving combined RT + ICI treatment had a higher risk of developing pneumonitis than those receiving ICI treatment alone (26.9 vs. 6.7 %, p<0.001). The multivariate logistic analysis identified the following independent risk factors for pneumonitis in patients undergoing combined RT + ICI treatment: history of lung disease (p=0.032), first-line ICI treatment (p=0.001), anti-PD-L1 instead of anti-PD-1 treatment (p=0.035), and the development of immunotherapy-related thyroid dysfunction (p=0.019). The independent risk factors were incorporated into a nomogram to predict the incidence of pneumonitis. The area under the receiver operating characteristic curve is 0.727, suggesting an acceptable predictive efficacy.

Conclusions

Compared to ICI monotherapy, NSCLC patients receiving the combination of thoracic radiotherapy and ICI treatment are at higher risk of developing pneumonitis. The nomogram holds promise for facilitating the risk assessment and early identification of pneumonitis in NSCLC patients receiving combined RT + ICI treatment.

New Vistas for the Relationship between Empathy and Political Ideology
Authors: Zebarjadi Niloufar , Kluge Annika , Adler Eliyahu , Levy Jonathan
Published: November 2024

The study of ideological asymmetries in empathy has consistently yielded inconclusive findings. Yet, until recently these inconsistencies relied exclusively on self-reports, which are known to be prone to biases and inaccuracies when evaluating empathy levels. Very recently, we reported ideological asymmetries in cognitive-affective empathy while relying on neuroimaging for the first time to address this question. In the present investigation which sampled a large cohort of human individuals from two distant countries and neuroimaging sites, we re-examine this question, but this time from the perspective of empathy to physical pain. The results are unambiguous at the neural and behavioral levels and showcase no asymmetry. This finding raises a novel premise: the question of whether empathy is ideologically asymmetrical depends on the targeted component of empathy (e.g., physical pain vs cognitive-affective) and requires explicit but also unobtrusive techniques for the measure of empathy. Moreover, the findings shed new light on another line of research investigating ideological (a)symmetries in physiological responses to vicarious pain, disgust, and threat.
Mildly elevated serum prolactin level may be a protective factor for preventing thickening of the carotid intima-media in patients with type 2 diabetes mellitus
Authors: Zhang Baoyu , Ke Jing , Zhang Ning , Zhao Wenying , Zhong Liyong
Published: November 2024

Objective

To evaluate the correlation between the serum prolactin (PRL) level and carotid intima-media thickness (CIMT) in patients with type 2 diabetes mellitus (T2DM).

Methods

In this study, 1,500 participants were divided into three groups based on the serum PRL level: hypoprolactinemia group (PRL ≤ 7 μg/L), normal PRL level group (7 μg/L < PRL ≤ 25 μg/L), and homeostatic functionally increased transient PRL (Ho-PRL) group (25 μg/L < PRL ≤ 100 μg/L). The independent-sample Kruskal–Wallis test was used to compare the CIMT among the three groups. The Spearman correlation test was used to examine the relationship between the CIMT, serum PRL level, and clinical data. Multivariate linear regression analysis was used to determine the independent factors that influence the CIMT.

Result

Individuals in the Ho-PRL group had a significantly lower CIMT compared to the hypoprolactinemia and normal PRL level groups (P < 0.001). The CIMT was positively correlated with age, systolic blood pressure (SBP), body mass index, duration of T2DM, and luteinizing hormone and follicle-stimulating hormone levels and negatively correlated with alanine transaminase and aspartate transaminase activities, estimated glomerular filtration rate, and PRL. Multivariate linear regression analysis revealed that only PRL was negatively associated with the CIMT, while age and SBP were positively associated with the CIMT.

Conclusion

In patients with T2DM, a PRL level within the mildly elevated range is negatively correlated with the CIMT. A mildly elevated serum PRL level may be a protective factor for preventing thickening of the carotid intima-media.
The Effect of US Uncertainty Shock on International Equity Markets: The Role of the Global Financial Cycle
Authors: Salisu Afees A. , Gupta Rangan , Adediran Idris A.
Published: November 2024

We contribute to the literature on the international propagation of uncertainty shocks with a Global Vector Autoregressive (GVAR) model that quantifies the spillover effects of uncertainty shocks in the US on to real equity prices of 32 advanced and emerging countries (besides the US). In this regard, we also account for the role of global financial market conditions in the propagation of these shocks, using high and low values of the Global Financial Cycle (GFCy) index. Using quarterly data over 1980:1 to 2019:2, our findings reveal greater response of advanced markets than emerging counterparts to an US uncertainty shock. Further, we show consistent higher negative responses during weak financial conditions than otherwise, confirming the intervening role of the GFCy index. Our results have important implications for investors and policymakers.
Patrón de poder colonial: síntesis y porvenir Sobre el artículo de Aníbal Quijano: “Colonialidad del poder, cultura y conocimiento en América Latina”, 1999
Authors: Ortega Pedro José
Published: November 2024

The work of Aníbal Quijano has played a pivotal role in bridging the gap between dependency theory and the decolonial movement. This premise finds its primary foundation in Quijano’s seminal article, “Coloniality of Power, Culture, and Knowledge in Latin America.” In this article, Quijano elucidates the historical evolution of the “pattern of colonial power,” a concept of profound significance and widespread recognition within decolonial discourse. For the sake of didactic clarity, this exposition distills three fundamental aspects of the colonial power pattern. These aspects not only elucidate the intricate connection between dependency and decoloniality but also delineate the overarching themes of the decolonial movement. These themes encompass a critique of modernity, Eurocentrism, and individualist capitalism, culminating in the articulation of a Latin American utopia struggling to establish its own legitimacy for critical examination. This, in turn, paves the way for a reconfiguration of the epistemic framework necessary for emancipation and social liberation. The three core facets of the decolonial current, as expounded in this article, include: a) The Intersection of Race and the Colonial Power Pattern, b) Subalternity and Its Relationship to Imitation, c) Eurocentric Hegemony and the Nexus of Material and Subjective Dependence. This article, while concluding with an open-ended perspective, underscores the enduring influence of Aníbal Quijano’s legacy within the realm of decolonial scholarship.
Colonialidad del poder, cultura y conocimiento en América Latina
Authors: Quijano Aníbal
Published: November 2024

El ensayo de Aníbal Quijano, escrito en 1997, abre algunas cuestiones fundamentales para comprender las profundas transformaciones que están ocurriendo en las relaciones materiales e intersubjetivas del poder en el Perú y en América Latina y el Caribe. El núcleo central del análisis gira en torno al conflicto, que ha dominado la historia de nuestras sociedades desde la constitución de América hasta la actualidad, entre las tendencias que se dirigen hacia una reoriginalización cultural y aquellas que se encaminan a mantener e, inclusive, profundizar la colonialidad del poder. Con el objeto de fundamentar este análisis explora las características y tendencias de la “experiencia histórica de la formación de la colonialidad del poder en América”, de un lado, y de otro, los heterogéneos procesos de subversión y reoriginalización cultural, siendo el más significativo el determinado por la emergencia del grupo cholo que se orientaba en la dirección de una “redistribución democrática de la autoridad”.
Evaluación de entornos peatonales en estaciones BRT
Authors: Gutiérrez-Alonso Israel
Published: November 2024

En toda ciudad la movilidad peatonal debería de fomentarse como opción de desplazamiento a escala local, pero esto no siempre es así. La administración pública destina una gran cantidad de recursos a la construcción de infraestructura para el transporte público masivo, con ese afán de modernidad que en poco o nada toma en consideración al peatón, que finalmente es el usuario al que se le dedica. El objetivo de la investigación fue evaluar la movilidad peatonal como medio del acceso al transporte público, con base en el entorno urbano construido, a partir de las variables de accesibilidad, seguridad, confort y atracción de desplazamientos en las estaciones y terminales del Corredor BRT Chimalhuacán–Nezahualcóyotl–Pantitlán. El análisis se realizó a las calles circundantes de las 28 estaciones y dos terminales del Corredor BRT en un radio de 100 m. En el estudio, de tipo correlacional se establecieron umbrales cuantitativos de análisis espacial para determinar cinco niveles de calidad peatonal, y de esta manera clasificar los entornos urbanos construidos de acuerdo al nivel de accesibilidad peatonal que permiten. Los resultados indican mínima planeación peatonal de los entornos urbanos construidos próximos al transporte público, lo que genera condiciones de inseguridad en los desplazamientos, accidentes viales, abandono del espacio público y una imagen urbana deteriorada. Se identificó la necesidad de contemplar en el diseño de este tipo de transporte público masivo las zonas de aproximación peatonal, toda vez que es estratégico su consideración para el éxito de su funcionamiento.

Published: November 2024

Challabamba in Cusco and Quilcas in Huancayo are two contrasting zones with high levels of biodiversity of potato varieties. The present study aimed to assess the spatial distribution of potato biodiversity through participatory mapping. We have assessed the potato cropping areas, the number of varieties in the communities, the altitudinal planting range of the potato varietal categories, the abundance and frequency of potato varieties, and the spatial-temporal dynamics of the cropping areas of potato in the territory at the landscape level. The study found 158 potato varieties in Challabamba and 194 in Quilcas. The research shows that the area devoted for the cultivation of potato landraces was higher in Challabamba (71.5%) than in Quilcas (51.8%) as compared to bred potato varieties. In Challabamba, 89.9 % of the potato varieties found are landraces and 10.1% are bred varieties. In Quilcas, 91.2 % of the potato varieties found are landraces and 8.8% are bred varieties. Half of the potato landraces are located within a narrow altitudinal range of less than 200m (between 3,800 and 4,000 m of altitude in Challabamba, and between 4,000 and 4,200 m in Quilcas). The remaining landraces show a more extended range distribution throughout the landscape. The relative frequency of varieties shows that 21.8% and 16.3% of varieties are considered abundant in Challabamba and Quilcas respectively, and the remaining (78.2% and 83.7) are varieties classified as scarce. Finally, we found that the fallow period of plots is 6 years before re-planting potatoes.

Authors: Torres W. , Tinoco O. , Huamantinco A. , Mialhe E. , Conde L.
Published: November 2024

The aquaculture activity in the white shrimp culture using recirculating water deteriorates the quality of the water by the hydrodynamic action of watermetabolites- organic matter, which generate negative impacts on the production of the crustacean. The objective of this research is to demonstrate that the autochthonous microbiota extracted from the red mangrove stimulates bioremediation. For this purpose, the microbiota was subjected to a process of bioaugmentation that enriches its biodiversity, so that when used, it guarantees bioremediation activity. The application of the treatment begins with the diagnosis of water quality in the different stages of the process, through the monitoring of toxic compounds such as ammonium, nitrites and nitrates and the evaluation of microbial biodiversity using metagenomic techniques such as the Reaction Test of the Polymerase, Electrophoresis in DNA testing and sequencing using the ILLUMINA technique. The results reveal that the toxic parameters maintain optimum levels of quality with the application of the microbiota composed of 1780 microbial species. Statistically it was demonstrated the significant decrease of levels of toxic compounds that the hypothesis proves, that the red mangrove microbiota acts efficiently in the bioremediation of water in the white shrimp culture.
Metodología para la identificación de variables representativas en la captura de datos in situ de espectroscopía
Authors: Valbuena Gaona Martha Patricia
Published: November 2024

Spectral signatures are graphical representations that relate the electromagnetic spectrum to the wave response or amplitude, resulting from the interaction of objects and light. Each soil cover, due to the different composition of materials, generates a particular spectral response. Therefore, the automated classification of coverages, whether object-oriented or pixel-oriented, is based on the spectral response of the different segments or pixels, respectively. Spectral libraries are databases where these spectral responses are stored so that researchers or organizations involved in the collection, processing and analysis of these samples can work collaboratively, avoiding redundancy in the investigations and optimizing time in the development of the same. However, there is currently no defined metadata model to ensure interoperability between researchers or organisations that generate spectral signatures, so as a first step, it is necessary to identify those variables that turn out to be representative in the capture of spectral signatures. To make the respective parameter definition, different field coverage signatures are captured and spectrality is compared from the Spectral Angle Mapper - SAM algorithm.
Deblurring Medical Images Using a New Grünwald-Letnikov Fractional Mask
Authors: Satvati Mohammad Amin , Lakestani Mehrdad , Khamnei Hossein Jabbari , Allahviranloo Tofigh
Published: November 2024

In this paper, we propose a novel image deblurring approach that utilizes a new mask based on the Grünwald-Letnikov fractional derivative. We employ the first five terms of the Grünwald-Letnikov fractional derivative to construct three masks corresponding to the horizontal, vertical, and diagonal directions. Using these matrices, we generate eight additional matrices of size $5\times 5$ for eight different orientations: $\frac{k\pi }{4}$, where $k=0,1,2,\dots ,7$. By combining these eight matrices, we construct a $9\times 9$ mask for image deblurring that relates to the order of the fractional derivative. We then categorize images into three distinct regions: smooth areas, textured regions, and edges, utilizing the Wakeby distribution for segmentation. Next, we determine an optimal fractional derivative value tailored to each image category to effectively construct masks for image deblurring. We applied the constructed mask to deblur eight brain images affected by blur. The effectiveness of our approach is demonstrated through evaluations using several metrics, including PSNR, AMBE, and Entropy. By comparing our results to those of other methods, we highlight the efficiency of our technique in image restoration.
From field to contact: relations and affections in teaching placement
Authors: Filho Rubens Pinto dos Santos
Published: November 2024

This paper explores the multifaceted nature of teacher training placements, emphasizing the interconnectedness of teaching, research, and outreach within the pedagogical framework. Drawing on Schopenhauer's notion of beauty as a relational encounter, the study argues against a simplistic understanding of teacher training that overlooks the critical dimension of praxis. The authors, Pimenta and Lima, highlight the limitations of conventional training curricula, suggesting they often present isolated subjects without meaningful connections to real-world contexts. The concept of imitation in teaching practice is examined, contrasting it with the richer notion of mimesis, which encompasses competition and emulation. Furthermore, the internship is positioned as a vital research experience that fosters a blend of intuition and practical engagement, informed by Deleuze's interpretation of Bergson's philosophy. This approach emphasizes the importance of duration, memory, and vital impulse in shaping the intern's journey, advocating for a methodological understanding that transcends the confines of empirical analysis. The paper ultimately calls for a re-evaluation of teacher training placements as dynamic sites of learning that are essential for the development of critical educators.
Van der Waals magnetic materials for current-induced control toward spintronic applications
Authors: Ryu Jeongchun , Kajale Shivam Nitin , Sarkar Deblina
Published: November 2024

Spintronics, leveraging electron spin for information processing, promises substantial advancements in energy-efficient computing. Van der Waals (vdW) magnetic materials, with their unique-layered structures and exceptional magnetic properties, have emerged as pivotal components in this field. This report explores the current-based control of vdW magnets, focusing on the spin–orbit torque (SOT) mechanism, which is crucial for spintronic applications.

"EN PRENSA" Calostro como parte del tratamiento en hipoglucemia neonatal sintomática. "EN PRENSA"
Authors: Contreras Garduño Katia Andrea , Rojas Mayorquín Argelia Esperanza
Published: November 2024

La hipoglucemia neonatal (HN) es una condición frecuente cuyo diagnóstico y manejo siguen siendo controversiales. El establecimiento y mantenimiento de la lactancia pueden verse afectados en pacientes con HN.  Para evitar daño neurológico, se recomienda infusión intravenosa de glucosa en pacientes con HN sintomática.  La administración intraoral de calostro como intervención ha sido poco explorada. Reportamos el caso de un recién nacido con HN sintomática cuya primera intervención fue la administración oral de calostro con una respuesta favorable.  Conclusiones: La calostroterapia en el manejo de HN es una intervención de bajo costo, no invasiva y favorece el establecimiento de la lactancia.
IDENTIDAD Y ANTAGONISMO EN EL PENSAMIENTO DE ERNESTO LACLAU
Authors: Herrera Hugo E.
Published: November 2024

RESUMEN En el presente trabajo se intentará determinar los aspectos fundamentales del pensamiento de Laclau a partir de la consideración del papel central que tienen en él el sujeto y lo otro, tanto en el ámbito individual como en el colectivo o político. Si bien las diferencias son condición de la actualización de la consciencia, se mostrará que la concepción del sujeto de Laclau presenta ciertas insuficiencias, las cuales se vuelven especialmente relevantes al momento de abordar lo político. Es pertinente advertir, como hace Laclau, respecto de los límites de una concepción política cuya base es una identidad individual y colectiva soberana. Sin embargo, se ha de reparar en el significado unitario que también define la existencia individual y colectiva. Para la consideración de la relación de identidad y diferencia, se acudirá a discusiones de alta significación en este asunto, y que tienen lugar en el contexto del idealismo y el romanticismo alemán (en particular a Kant Fichte, Hölderlin y Schelling). Hecha la salvedad sobre la dificultad indicada, se tratará de mostrar en qué sentido la concepción política antagonística de Laclau es adecuada para una comprensión no reduccionista de la indeterminación y alteridad que constan con lo político, y que vuelven imposible e indeseable su reducción, sin resguardos suficientes, según parámetros racionales.
TOCQUEVILLE Y KIERKEGAARD ANTE EL FENÓMENO DE LA NIVELACIÓN EN LA SOCIEDAD DE MASAS
Authors: Quer Matías
Published: November 2024

RESUMEN El artículo analiza el concepto de nivelación como fenómeno político y social en la sociedad de masas del siglo XIX por parte de Tocqueville y Kierkegaard. Se explica el uso de la nivelación en las obras de ambos autores y, posteriormente, se realiza un análisis comparativo que permite encontrar los aspectos en común y las diferencias que existen entre los dos. El análisis permite comprender la complejidad del fenómeno de la nivelación y de la igualdad democrática, considerando sus efectos sobre los individuos y sus vínculos sociales en la sociedad de masas.
THE ROLE OF EXTERNALISM IN UNSAFE BUT RATIONAL REASONING
Authors: Pereira Roberto Horácio de Sa
Published: November 2024

ABSTRACT Faria’s recent publication aims to show that “if anti-individualism is correct, then the obscurity of validity is more widespread than we need to assume for present purposes.” In rejecting “a variety of exculpating moves, designed to shield the rationality of the possibly unlucky reasoner,” Faria suggests that content externalism can drastically affect our self-understanding as rational beings. I am afraid I have to disagree. Faria overintellectualizes reasoning, always performed from the first-person perspective and is subject to reflexive control by the reasoner. To be sure, content externalism shows that sound reasoning is contingent on the broad environment and therefore does not depend exclusively on the logical abilities of the living being but is a matter of logical luck. Nonetheless, content externalism is no threat to rationality. My diagnosis: By adopting Wittgenstein’s strategy of “bringing words back home,” Faria overlooks the achievements of cognitive science: in its simplest form, “transitive inference,” rationality pervades the animal kingdom.
ENACTIVE EVALUATIVE SENTIMENTALISM
Authors: Vogelmann Rafael
Published: November 2024

ABSTRACT I argue for a version of evaluative sentimentalism according to which (i) affective responses are appearances of value and (ii) value judgments can repudiate or assent to these appearances. The starting point of my argument is Giovanna Colombetti’s enactive conception of affectivity. According to Colombetti, an affective being is one that through its sense-making activity enacts meaningful value-laden distinctions and, thus, brings forth an Umwelt (i.e., an environment that has a specific significance for it). The elements of that Umwelt strike the affective being as meaningful or valuable and to be thus struck is to be affected by those things. In that sense, affective responses can be characterized as appearances of value. I hold that appearances of value are best understood as perceptions of affordances. This view has consequences for our understanding of value judgments. The evaluative concepts that are relevant to us must map onto distinctions that are meaningful to us. As such, relevant evaluative concepts must capture the significance of the elements in the Umwelt that affect the organism. The upshot is that the significance value judgments ascribe to their objects can coincide with the meaning with which the object is presented to us in an affective response.
O conceito de era axial: raízes, desenvolvimento e atualidade
Authors: Sell Carlos Eduardo , Eccel Daiane
Published: November 2024

Resumo: O artigo realiza um mapeamento histórico, epistemológico e crítico das raízes, consolidação e retomada do conceito de era axial, com destaque para seu momento de solidificação, com o livro Origem e meta da história, de Karl Jaspers (1949). A partir da análise das características epistemológicas de cada uma dessas etapas, demonstram-se os elementos de continuidade, assim como os que se modificam, na compreensão daquilo que é a era axial. Enquanto, nas duas primeiras fases (histórica e filosófica), havia uma maior ênfase na simultaneidade e na igualdade entre civilizações, seu deslocamento para o campo da sociologia (fase 3), implicou maior relevo para a diversidade de civilizações. Destaca-se que, na fase atual, diferente das etapas anteriores, o conceito se desloca da análise das civilizações pré-modernas para a análise da civilização moderna como um tipo de era axial. Apesar disso, entende-se que existe uma base comum presente em todas as fases da discussão. A investigação conclui que, a despeito de certas leituras evolucionistas aqui criticadas, a utilização do conceito de era axial, seja em chave histórico-filosófica, seja em chave sociológica, contém pressupostos cosmopolitas e plurais e, como tal, continua a ser um importante recurso analítico para a compreensão da complexidade e diversidade cultural das civilizações do passado e do presente.
Development of ecological consciousness through urban design and development
Authors: Li Xiaodan , Feng Dongzhu
Published: November 2024

Abstract: Growing environmental concerns and the rise of sustainable development have made planners shift focus from prioritizing economic and social benefits to incorporating ecological consciousness into urban planning. Ecological challenges, such as habitat degradation from unchecked urban expansion and insufficient green spaces, underscore gaps in ecological awareness among urban planners. Issues, like urban heat islands and water mismanagement, further exemplify the need for enhanced ecological planning. To address these challenges, the paper proposes several governance strategies. It advocates for comprehensive planning for ecological civilization cities, including green infrastructures and natural landscape restoration to mitigate environmental impacts. Enhancing ecological responsibility, through education and community engagement, is vital for fostering a culture of sustainability. Developing an ecological circular economy addresses resource inefficiency and waste problems, while promoting low-carbon transportation options aims to reduce urban carbon footprints. Guided by the concept of ecological consciousness, this analysis offers actionable paths for improving urban ecological governance.
The development of the aesthetic spirit connotation of modern Chinese art
Authors: Zhuo Yali , Hou Guanhua
Published: November 2024

Abstract: This study analyzed the historical background of Chinese art thought in the early 20th century, the idea of “integration of China and the West”, and the painters and their works that have had a significant impact on it. By studying the trend of Chinese art popularization and its impact on student education in art schools, it revealed the impact of the changes in Chinese art thought in the early 20th century on modern art thought. At the beginning of the 20th century, the evolution of Chinese art thought underwent a reform of art thought. It has influenced many painters’ creative spirit and techniques , and has influenced the development of modern Chinese art thought. The research into the early 20th-century evolution of Chinese art thought reveals a pivotal era of diversification in aesthetic values and ideas among various artists, propelling Chinese art into a vibrant period of flourishing styles and philosophies.
