Authors: Gomez Segura Camilo Fabiam , Cuellar Adames Andres David , Martínez Alvarado Laura Camila
Published: May 2023

El objetivo de este artículo es analizar la relación que existe entre el gasto público dirigido al sector de la educación, la salud y al área de investigación y desarrollo, y el crecimiento económico de los países suramericanos, durante el periodo 1995-2018. Dada la estructura de los datos, se estimó un modelo de datos de panel en sus especificaciones de primeras diferencias, efectos fijos y efectos aleatorios. Al controlar por heterocedasticidad y autocorrelación serial se obtiene como resultado que el gasto en educación es el único que está influyendo de manera positiva en el crecimiento económico, mientras que del gasto de los otros sectores no existe suficiente evidencia empírica para afirmar que tuvo un impacto en el desarrollo de las economías suramericanas.

¿En qué consiste la crisis de la educación?
Authors: Rubio David , Heredia María
Published: May 2023

La crisis de la educación puede leerse en distintos niveles y con arreglo a distintos encuadres históricos. Por eso, la crisis deviene en críticas sobre las prácticas escolares, sobre los métodos de la enseñanza, o sobre la falta de relación entre los logros educativos y los problemas económicos. Comprendida así, las crisis son múltiples y, por qué no, permanentes. Sin embargo, en el artículo se propone una lectura distinta. Lo que está en crisis es la educación como acontecimiento histórico. Para ello, acudimos a una revisión sobre los límites conceptuales de la «crisis», así como a la caracterización de la educación como concepto moderno, mediante la lectura de algunos trabajos pertenecientes al canon de la pedagogía. Al final, se plantea que la crisis implica el tránsito hacia una forma de la educación que tiene un sentido antropológico distinto, relacionado con un declive de los fines educativos emparejados con la noción de futuro, que se reemplazó, en el siglo XX, por una idea de presente permanente.

Ensuring an Effective Social Protection Response in Conflict-Affected Settings: Findings from the Horn of Africa
Authors:   Institute of Development Studies, Birch Izzy , Carter Becky , Lind Jeremy , Sabates-Wheeler Rachel
Published: May 2023

The interaction between social protection and conflict is an emerging area of study with particular relevance to the Horn of Africa, where conflict and political instability are habitual risks and where social protection is now a well-established field of intervention, including in response to climate-related shocks. Yet the connection between these two policy areas is poorly articulated. While frontline practitioners may be acutely aware of, and responsive to, conflict and political dynamics, these are less well reflected in the frameworks that guide social protection policy and programming.

Published: May 2023

The development of information technology have an impact on cyber crimes such as identity theft, fraud, and misuse of personal data. One of the crimes, abuse of personal data is doxing. It was an illegal act to spreading action people's personal information or data without permission and creates dangerous situations, humiliation, harassment, or other adverse which can lead to spoilage of the victims. The act of doxing or disseminating personal data has recently increased, especially among journalists. Doxing is a transmission system of personal data conducted by journalists legally. The freedom of journalists who compose and develop news to encourage misuse of personal data. In this case, we are interested in studying the legal basis of doxing and personal data dissemination in Indonesia, with the objectives: first, does the regulation of distributing personal data (doxing) in the Electronic Information and Transaction Law encounter the doxing typology? second How is the reformulation of the criminal law policy on the act of spreading personal data (doxing) in fulfilling the doxing typology? This research adopted normative legal research and used a statutory approach, conceptual approach, and comparative approach. The results showed that the act of doxing in the ITE Law does not regulate it according to the doxing typology. Therefore, there is a need to reform criminal law policies in the ITE. It can also be through the Bill of Personal Data Protection. The government must compose a regulation on disseminating personal data or doxing in the Law concerning Electronic Information and transactions.
Demandas em torno da responsabilização nas políticas de currículo e docência: os organismos multilaterais e suas articulações em tempos de crise
Authors: Soares Ana Paula
Published: May 2023

Os organismos multilaterais e suas agendas têm exercido cada vez mais influência (em diferentes escalas) na produção de políticas com o foco na docência, que visam assegurar o envolvimento dos professores com as proposições para o currículo, promovendo mudanças no trabalho docente marcadas pela responsabilização (DIAS, 2013, 2016, 2021). O presente artigo busca analisar como a responsabilização vem sendo articulada e apresentada como demanda em âmbito global por organismos multilaterais e as reverberações desses nas políticas de currículo e docência local, em contextos nos quais circulam discursos de “crise da educação” (MACEDO, 2014). O foco são produções que contam com a colaboração da Organização das Nações Unidas para Educação, Ciência e Cultura (UNESCO). As análises são feitas a partir de referenciais pós-estruturais, pós-fundacionais, que compreendem as políticas como práticas discursivas. É possível observar a manutenção das políticas de currículo para formação de professores sendo postas como principal estratégia para a melhoria da qualidade da educação em âmbito global, o que reforça demandas em torno da responsabilização docente no contexto local.

Authors: Lin Xiang , Han Mengdi
Published: May 2023

Recent advancements in soft electronics and robotics have expanded the possibilities beyond the capabilities of traditional rigid devices, indicating promise for a range of applications in electronic skins, wireless biomedical devices, and others. Magnetic materials exploited in these soft systems can further broaden the modalities in sensing and actuation. These magnetic materials, when constructed in the forms of nanoparticles, nanomembranes, or other types of nanostructures, exhibit some unique characteristics, such as the magnetoresistance effect and size-dependent coercivity. Soft electronics and robotics employing such magnetic nanomaterials offer a variety of functions, including the detection of the intensity and direction of magnetic fields, measurement of various types of mechanical deformations, manipulation and transport at small scales, and multimodal complex locomotion in a controllable fashion. Despite recent advancements in soft electronics and robotics, challenges remain in developing advanced materials and manufacturing schemes to improve performance metrics and facilitate integration with other devices. This review article aims to summarize the progress made in soft electronics and robotics based on magnetic nanomaterials, with an emphasis on introducing material and device performance. The discussions focus on soft electronics and robotics based on magnetic nanomembranes/nanostructures and magnetic composites. As a concluding remark, this article summarizes the current status of the field and discusses opportunities that underpin future progress.

Este artigo tem como objetivo analisar as dificuldades e possibilidades do ensino de Biologia, em tempos de pandemia da Covid-19, por meio da produção e utilização das Histórias em Quadrinhos. Para coleta de dados, os estudantes produziram História em Quadrinhos (HQ) sobre a pandemia da Covid-19 e, responderam questionário com questões abertas e fechadas. Adotamos como referencial teórico e metodológico a Análise de discurso, mobilizando dispositivos analíticos como leitura, interdiscurso e mecanismo da antecipação. Os resultados demonstram que é possível ensinar e aprender conhecimentos relativos às ciências biológicas utilizando HQs. Partindo de que as aulas remotas têm se apresentado geralmente de forma bastante enfadonha e desinteressante, consideramos que as HQ, produzidas pelo Pixton, foi uma alternativa possível para o ensino de conceitos científicos conectados com as situações cotidianas que os educandos vivenciam.

Authors: Tavares Bruno
Published: May 2023

Neste estudo, analiso a construção e desenvolvimento de uma sequência didática sobre a temática de intersexualidade, voltada para estudantes do 8º ano do ensino fundamental. A elaboração e análise da sequência didática foram embasadas nos estudos feministas e de gênero, com foco nas feministas biólogas. O objetivo da sequência foi problematizar o binário rígido masculino/feminino, a partir da discussão sobre casos de intersexualidade. Por meio desta prática pedagógica, constatei que as/os discentes refletiram sobre o binário maculino/feminino, seja no estudo anatômico-fisiológico intersexual, ou quando entraram em contato com reivindicações políticas do movimento intersexual brasileiro. Enfim, é preciso discutir mais sobre intersexualidade no ensino de ciências, abarcando as diversidades intersexuais como possibilidades fora do viés patológico.
VIAJAR-MUNDOS HACIA EL SUJETO DE LA CIENCIA Y DE LA FORMACIÓN DE PROFESORES DE CIENCIAS
Authors: Alvarado Guzmán Lisbeth Lorena , Zuleta Mara Karidy Polanco
Published: May 2023

O objetivo deste artigo é levantar algumas reflexões sobre o sujeito da ciência e suas implicações na educação científica, bem como propor uma visão da práxis educacional a partir do conceito de viajar-mundos de María Lugones. De uma revisão documental, algumas críticas ao tema hegemônico da ciência e da ciência androcêntrica são coletadas de epistemologias feministas. Também revisamos a relação entre conhecimento, gênero e ciência sob a perspectiva do feminismo descolonial e estudos sobre a descolonalidade do conhecimento. De uma perspectiva descolonial é possível compreender a inseparabilidade de categorias como raça, classe, gênero e localização geopolítica, entre outras, para a análise do sistema de conhecimento moderno/colonial. Neste sentido, a relação vertical da universidade com a escola e sua conseqüente abordagem da teoria sobre a prática, bem como a divisão hierárquica do conhecimento no sistema educacional, são entendidas como formas de reproduzir as diversas opressões e exclusões do sistema de gênero moderno/colonial. Finalmente, argumenta-se que a luta dos professores para serem reconhecidos como sujeitos epistêmicos é também uma luta pela justiça epistêmica e social, portanto, conceber os professores como viajantes de mundos poderia contribuir para uma práxis para a transformação social na América Latina. Isto requer o estabelecimento de coalizões e colaborações na educação científica através de redes e da criação de mundos para estar com outros.

Published: May 2023

Age-related Macular Degeneration (AMD) is the major cause of elders’ vision loss, early screening and treatment are the most efficient way to reduce the rate of blindness. AI-based methods based on ophthalmic images play great potential for AMD diagnosis. However, low levels of accuracy, robustness, and explainability are challenges for AI approaches applied in clinics. Thus, this study proposed a multi-type of data source fusion method and a multi-model fusion approach for AMD detection. Typical unsupervised (Hierarchical Clustering and K-Means), typical supervised (SVM, VGG-16, and ResNet) methods, and proposed methods (multi-source data fusion-based method and multi-model fusion-based approach) are compared based on Optical Coherence Tomography (OCT), Fundus Autofluorescence (FAF), regular color fundus photography (CFP) and Ultra-Wide field Fundus (UWF) images. Data preprocessing and enhancements of each type of data are discussed. A feature extraction based on unsupervised ML models, feature combination and normalization, and multi-layer perception (MLP) algorithm are involved in the proposed multi-source data fusion-based method. Supervised ML and DL models and a voting mechanism are involved in the multi-model fusion-based approach. Findings show that the proposed methods present a high performance of accuracy and robustness. A real-world UWF database is involved from Shenzhen Aier Hospital. Practical and theoretical contributions are delivered. A reference value for medical diagnosis based on multiple digital images is contributed.

Published: May 2023

Antimicrobial resistance has become a significant public health problem globally with multidrug resistant Gram negative (MDR-GN) bacteria being the main representatives. The emergence of these pathogens in neonatal settings threatens the well-being of vulnerable neonatal population given the dearth of safe and effective therapeutic options. Evidence from studies mainly in adults is now available for several novel antimicrobial compounds, such as new β-lactam/β-lactamase inhibitors (e.g. ceftazidime-avibactam, meropenem-vaborbactam, imipenem/cilastatin-relebactam), although old antibiotics such as colistin, tigecyclin and fosfomycin are also encombassed in the fight against MDR-GN infections that remain challenging. Data in the neonatal population are scarse, with few clinical trials enrolling neonates for the evaluation of efficacy, safety and dosing of new antibiotics, while the majority of old antibiotics are used off-label. In this article we review data about some novel and old antibiotics that are active against MDR-GN bacteria causing sepsis and are of interest to be used in the neonatal population.
Plant Phenology Simulation and Trigger Threshold Based on Total Climatic Production Factors – a Case Study of Stipa krylovii Phenology
Authors: Zhou Guangsheng , Gu Wenjie , Zhou Li , Song Xingyang , Lv Xiaomin , Liu Erhua , Ji Yuhe
Published: May 2023

In response to the new concept of the impact of total climate production factors on plant phenology, this study will verify the feasibility of simulating plant phenology and triggering thresholds based on total climatic production factors by using the phenological and meteorological observation data of S. krylovii plant from 1985 to 2018 at the Xilinhot National Climate Observatory of China Meteorological Administration. The results indicate that the total climate production factors influencing plant phenological changes can be well used for phenological simulation and its triggering thresholds. The mutation of cumulative climate production potential based on total climate production factors can effectively indicate the green-up date and the wilting date of S. krylovii plant, and their triggering thresholds depend on the parameters of climate resource change and plant biology, which are (0.085, –5.363) and (0.086, –27.620), respectively. The cumulative climate production potential based on total climate production factors can effectively indicate the heading date of S. krylovii plant, and its triggering thresholds also depends on the parameters of climate resource change and plant biology, which is (394.632，–38026.268). Furthermore, the results support the viewpoint that the climate abrupt changes determine the beginning and the ending of plant growth, while the accumulative climate resources determine the other phenological dates. This study provides new ideas for the study of plant phenology.
Performance Improvement of Multi-Robot Data Transmission in Aggregated Robot Processing Architecture With Caches and QoS Balancing Optimization
Authors: Jalil Abdul , Kobayashi Jun , Saitoh Takeshi
Published: May 2023

Robot Operating System 2 (ROS 2) is a robotic software that uses a set of Quality of Service (QoS) policies to manage the quality of robot data transmissions in a network, such as the RELIABLE and KEEP_LAST options. In ROS 2 node communication, the RELIABLE connection guarantees that all message data can be properly sent from the publisher to the subscriber. However, strict reliability is not guaranteed if the RELIABLE connection uses the KEEP_LAST option to transmit the robot data in the publish-subscribe communication. This study aims to analyze the efficiency of local cache, cache control, and QoS balancing optimization to improve ROS 2 node communication when using the RELIABLE and KEEP_LAST options to transmit multi-robot data in Aggregated Robot Processing (ARP) architecture. Our idea in local cache and cache control is to streamline the sensor data output before processing it when the sensor device produces the data with the same value in a row. Furthermore, QoS balancing optimization aims to balance the DEPTH and DEADLINE QoS configuration to determine the rates and buffer size in ROS 2 node communication. This study shows that combining local cache and QoS balancing optimization improves multi-robot data transmission and cooperation in ARP architecture.

Published: May 2023

The Infectious and Tropical Diseases Department of University of Brescia organized free rapid screening tests for HIV and HCV as part of the Fast Track City commitment. A cross-sectional study was conducted, consisting of an anonymous, multiple-choice questionnaire that was administered to individuals who underwent the screening or consultation. The study aimed to compare knowledge and attitudes towards HIV and HCV between age groups (18-40 vs. >40) and sexual orientations (heterosexual vs. LGBTQ+). Overall, 333 questionnaires were completed. Individuals over the age of 40 and those who identified as heterosexual had the lowest level of knowledge about HIV transmission (7.9% and 30% respectively), undetectable=untransmittable (19.7% and 39.4% respectively) and PrEP (9.2% and 18.2% respectively). They were also less willing to cohabit with people with HIV (PLHIV). Only 9.6% of the population demonstrated high levels of knowledge for both HIV and HCV. People over the age of 40 had the largest gaps in knowledge and would benefit the most from educational and prevention interventions.

Published: May 2023

The adoption of recycling and proper disposal techniques for electronic waste is crucial in advancing sustainable development. The traditional approaches of motivating people for collection of electronic waste are often insufficient due to inadequate methods reaching out, given incentives, calculating appropriate incentives associate to the task of gathering the electronic waste and a lack of transparency in the entire process. Insufficient collection of electronic waste could result in the release of numerous harmful substances into the environment. Prior research studies have been carried out to tackle the issue of electronic waste management in a broad sense. The findings of those studies indicated diverse strategies, each of which is relevant solely to a restricted range of electronic waste reprocessing circumstances. The current study has presented a proposed technique for incentivizing tasks and activities associated to collection of electronic waste through the adoption of vector space technique. Blockchain smart contact technology, has been used to implemented the strategy. The method used involves various well defined mapping of tasks, nature of activities, and their magnitude in order to derived an incentive. Some scenarios for the calculations of incentives are presented, and the findings reveals the based case is by utilizing weighting scale scheme where each tasks and activities are mapped to its associated inventive rather than providing fixed incentive values. Ethereum was used as digital token for each unit of incentive. This concept has contributed in encouraging personal accountability in the management of e-waste collection in order to cultivate sustainable behaviors for a long term solution.

Published: May 2023

On the aero-engine combustor liner, a phenomenon of overheating resembling a hot spot exists, accompanied by a preferential peeling of the YSZ thermal barrier coating that will negatively affect the service life of the component. The temperature gradient of the hot spot may affect the YSZ fracture pattern.In this paper, the morphological and property changes of YSZ sintering is investigated experimentally, and a coupled analysis of the YSZ Crack Propagation Mode under the hot spot is performed using ABAQUS. The results show that the pore fractal size D of YSZ increases by 15%. Inside the hot spot region, the coating has a shear stress of 75MPa. By inserting Cohesive units globally in the model to simulate the random crack initiation and propagation, unlike the thinning of YSZ layered peeling caused by uniform superheating, hot spot will cause the crack initiation at the tip of the pores inside the coating and the oblique propagation, eventually forming an oblique crack connection through the pores. When the temperature gradient reaches 30K/mm, the crack propagation is 40% greater than in a uniform temperature field; consequently, the YSZ in the hot spot boundary region with a greater temperature gradient results in more severe bulk peeling.

To improve the wear resistance of polyimide (PI), surface modification was developed. In this study, the tribological properties of graphene (GN), graphene oxide (GO), and KH550-grafted graphene oxide (K5-GO) modified PI were evaluated by molecular dynamics (MD) at the atomic level. The findings indicated that the addition of nanomaterials can significantly enhance the friction performance of PI. The friction coefficient of PI composites decreased from 0.253 to 0.232, 0.136, and 0.079 after coating GN, GO and K5-GO, respectively. Among them, the K5-GO/PI exhibited the best surface wear resistance. Importantly, the mechanism behind the modification of PI was thoroughly revealed by observing the wear state, analyzing the changes of interfacial interactions, interfacial temperature, and relative concentration.

Authors: Hong Sung-Ho , Jang Eun Kyung
Published: May 2023

In this study, the literature on varnish contamination is investigated among the various con-taminations of lubricant. As the period of use of lubricant increases, the lubricant deteriorates and becomes contaminated. The varnish causes filter plugging, sticking of hydraulic valves and fuel injection pumps, obstruction of flow, reduction of clearance, poor heater and cooler perfor-mance, and increase of friction and wear in various lubrication systems. These problems also cause mechanical system failure, performance degradation, and increased maintenance and re-pair cost. To improve the problems causes by the varnish, an adequate understanding of varnish is required. Therefore, in this literature review, definitions and characteristics, generating ma-chinery, generating mechanisms, causes, measurement methods, and prevention or removal methods are summarized. Most of the data are reports of companies related to lubricant and machine maintenance, and are included in some papers. We hope that this summary of varnish will be helpful to those who are engaged in reducing or preventing varnish problems.

Published: May 2023

Lead-free copper halide perovskite nanocrystals (NCs) are emerging materials with excellent photoelectric properties. Herein, we present a colloidal synthesis route of orthorhombic Cs2CuCl4 NCs with well-defined cubic shape and an average diameter of 24 ± 2.1 nm. The Cs2CuCl4 NCs exhibit bright deep blue photoluminescence, which is attributed to the Cu(II) defects. In addition, passivating the Cs2CuCl4 NCs by Ag+ can effectively improve the photoluminescence quantum yield (PLQY) and environmental stability.

Coronavirus 19 disease (COVID-19) may be complicated by thrombotic events, particularly venous thromboembolism (VTE), which have been reported both in critically ill hospitalized patients and in individuals with mild symptoms. It is known that the chronic use of oral contraceptive pills (OCPs) is associated with higher risk of VTE. To date, there are only few reports concerning the association of OCPs and VTE/pulmonary embolism (PE) in COVID-19 patients. Given that during the convalescent phase of disease, a state of endothelial dysfunction, hypercoagulability and a low-grade inflammation may be persistent, the occurrence of thromboembolic events following acute COVID-19 infection may be not surprising. Herein, we report a case of high-risk PE detected in a post-COVID-19 young woman under hormonal contraception, which required thrombolytic treatment. A number of prothrombotic phenomena, such as overweight, hormonal contraceptive therapy, recent COVID-19 infection and prolonged immobilization, might have synergically contributed to the development of a sublethal thromboembolic event.
New Discoveries on Molecules Inducing Dental Stem Cells Differentiation and Bone Regeneration

Published: May 2023

Teeth include mesenchymal stem cells (MSCs), which are multipotent cells that promote tooth growth and repair. Dental tissues, specifically the dental pulp and the dental bud, constitute a relevant source of multipotent stem cells, known as dental-derived stem cells (d-DSCs): dental pulp stem cells (DPSCs) and dental bud stem cells (DBSCs). Cell treatment with bone-associated factors and stimulation with small molecule compounds are, among the available methods, the ones who show excellent advantages promoting stem cell differentiation and osteogenesis. Recently, attention has been paid to studies on natural and non-natural compounds. Many fruits, vegetables and some drugs contain molecules that can enhance MSC osteogenic differentiation and therefore bone formation. The purpose of this review is to examine research work over the past 7 years that has investigated two different types of MSCs from dental tissues that are attractive targets for bone tissue engineering: DPSCs and DBSCs. We focused on articles hypothesizing the identification and study of compounds that induce proliferation and osteogenic differentiation of the two d-DSC populations, representing an interesting issue for regenerative medicine. The reconstruction of bone defects in fact is still a challenge for personalized medicine.

Published: May 2023

Oil-tea (Camellia oleifera) is a woody oil crop whose nectar includes galactose derivatives that are toxic to honey bees. Interestingly, some mining bees of the genus Andrena can entirely live on nectar (and pollen) of oil tea and are able to metabolize these galactose derivatives. We present the first next-generation genomes for five and one Andrena species that are respectively specialized and non-specialized oil-tea pollinators, and combining with published genomes of six other Andrena species which did not visit oil-tea, we performed molecular evolution analyses on genes involved in metabolism of galactose derivatives. Six genes (NAGA, NAGA-like, galM, galK, galT, and galE) involved in galactose derivatives metabolism were identified in the five oil-tea specialized species, but only five (with the exception of NAGA-like) were discovered in the other Andrena species. Molecular evolution analyses revealed that NAGA-like, galK and galT in oil-tea specialized species appeared under positive selection. RNASeq analyses showed that NAGA-like, galK, and galT were significantly up-regulated in the specialized pollinator A. camellia compared to the non-specialized pollinator A. chekiangensis. Our study demonstrated that the genes NAGA-like, galK, and galT had played an important role in the evolutionary adaptation of the oil-tea specialized Andrena species.
Running Vacuum in the Universe: Phenomenological Status in Light of the Latest Observations, and Its Impact on the σ8 and H0 Tensions

A substantial body of phenomenological and theoretical work over the last few years strengthens the possibility that the vacuum energy density (VED) of the universe is dynamical, and in particular that it adopts the `running vacuum model' (RVM) form, in which the VED evolves mildly as $\delta \rho_{\rm vac}(H)\sim \nu_{\rm eff} m_{\rm Pl}^2{\cal O}\left(H^2\right)$, where $H$ is the Hubble rate and $\nu_{\rm eff}$ is a (small) free parameter. This dynamical scenario is grounded on recent studies of quantum field theory (QFT) in curved spacetime and also on string theory. It turns out that what we call the `cosmological constant', $\Lambda$, is no longer a rigid parameter but the nearly sustained value of $8\pi G(H)\rho_{\rm vac}(H)$ around (any) given epoch $H(t)$, where $G(H)$ is the gravitational coupling, which can also be very mildly running (logarithmically). Of particular interest is the possibility suggested in past works that such a running may help to cure the cosmological tensions afflicting the $\Lambda$CDM. In the current study, we reanalyze it in full and we find it becomes further buttressed. Using the modern cosmological data, namely a compilation of the latest SNIa+BAO+$H(z)$+LSS+CMB observations, we probe to which extent the RVM provides a quality fit better than the concordance $\Lambda$CDM model, paying particular emphasis on its impact on the $\sigma_8$ and $H_0$ tensions. We utilize the Einstein-Boltzmann system solver \texttt{CLASS} and the Monte Carlo sampler \texttt{MontePython} for the statistical analysis, as well as the statistical DIC criterion to compare the running vacuum against the rigid vacuum ($\nu_{\rm eff} = 0$). On fundamental grounds, $\nu_{\rm eff}$ receives contributions from all the quantized matter fields in FLRW spacetime. We show that with a tiny amount of vacuum dynamics ($|\nu_{\rm eff}|\ll 1$) the global fit can improve significantly with respect to the $\CC$CDM and the mentioned tensions may subside to inconspicuous levels.
