Disciplinary Guarantees for the Public Employee in the Saudi Law
Authors: Alqurashi Dr. Yaser Salim
Published: November 2022

The Saudi law has granted the administration numerous disciplinary powers against the public employee in the area of its disciplinary responsibility; however, in light of these disciplinary and punitive powers of the administration, the public employee must be protected from any tyranny, abuse, injustice, or bargaining that may be exercised against him by some of the administration's people. As a result, these protections shield public employees from the administration's tyranny, persecution, and arbitrariness. Thus, the purpose of this research is to uncover the disciplinary guarantees for public employees in the Saudi law, as well as their sufficiency in protecting the public employee and guaranteeing that the administration does not use them as a means of tyranny or arbitrariness. The study subject concerned the adequacy of these guarantees in the Saudi legislation, and the significance of the research lay in determining the adequacy of these guarantees in order to achieve protection for public employees. Furthermore, the researcher employed the descriptive, analytical, and comparative method, by collecting facts and data, analyzing them, and comparing them in order to elucidate the features linked to the study's issue. Finally, the study's results revealed that there are some problems in achieving guarantees of protection for the public employee from the administration's arbitrariness and tyranny in the Saudi law, and the researcher suggested some amendments to the legislation related to the disciplinary responsibility of the public employee in the Saudi law to ensure his complete protection from any abuse or tyranny by the administration.
Grey Wolf Optimization Based Energy Management Strategy for Hybrid Electrical Vehicles
Authors: Gadge Gaurav , Pahariya Yogesh
Published: November 2022

Electric vehicles (EVs) are seen as a necessary component of transportation's future growth. However, the performance of batteries related to power density and energy density restricts the adoption of electric vehicles. To make the transition from a conventional car to a pure electric vehicle (PEV), a Hybrid Electric Vehicle's (HEV) Energy Management System (EMS) is crucial. The HEVs are often powered with hybrid electrical sources, therefore it is important to select the optimal power source to improve the HEV performance, minimize the fuel cost and minimize hydrocarbon and nitrogen oxides emission. This paper presents the Grey Wolf Optimization (GWO) algorithm for the control of the power sources in the HEVs based on power requirement and economy. The proposed GWO-based EMS provides optimized switching of the power sources and economical and pollution free control of HEV.

Pioartrite Em Recém-Nascido: Relato De Caso
Authors: Rodrigues Renan Brocchi de Moraes , Guerra Priscilla
Published: November 2022

Introdução: A pioartrite (PIOA), também conhecida como artrite séptica, é uma monoartrite aguda causada principalmente por bactérias comuns, como as dos gêneros Staphylococcus ou Streptococcus. Embora a PIOA em crianças não seja comum, não deve ser subestimada, pois pode estar associada à sepse e resultar em disfunção grave ou morte se não tratada precocemente e de forma adequada. Objetivo: Relatar um caso de PIOA em recém-nascido atendido no Serviço de Pediatria do Hospital Universitário São Francisco na Providência de Deus (HUSF), localizado na cidade de Bragança Paulista, SP.

Relato do Caso: Tratou-se de um recém-nascido de 14 dias cujos pais relataram queixas de irritabilidade, choro excessivo à manipulação e diminuição da motilidade do membro inferior esquerdo, que se apresentava edemaciado e ruborizado na região do quadril. O paciente foi avaliado pela equipe de Ortopedia, que o diagnosticou com PIOA, realizando limpeza e drenagem do quadril afetado, seguida de 21 dias de antibioticoterapia combinada, com remissão completa da doença.

Conclusão: Por conta de sua raridade, alta taxa de morbidade e mortalidade e falta de consenso internacional sobre a melhor antibioticoterapia a ser administrada, a PIOA em recém-nascidos e crianças continua sendo um grande desafio. Seu diagnóstico deve ser realizado com brevidade, buscando evitar a ocorrência de sequelas como o encurtamento de membros ou óbito.

Pieno mišinio vaidmuo vienerių metų ir vyresnių vaikų mityboje
Authors: Petereit Rūta
Published: November 2022

Subalansuota vaikų mityba turi didelę reikšmę darniam jų vystymuisi bei gyvenimo kokybei. Kūdikio maitinimas yra ne tik maisto medžiagų ir energijos poreikio patenkinimas, bet ir vaiko bei tėvų bendravimo pradžia, pasaulio pažinimas. Vaisiaus vystymasis ir pirmieji treji gyvenimo metai yra labai svarbūs metaboliniam programavimui, susijusiam su gretutinėmis ligomis vėlesniame amžiuje. Per pirmus kelerius žmogaus gyvenimo metus įvyksta itin dideli pokyčiai: greitas fizinis augimas (greičiausias augimas per visą gyvenimą), socialinis bei psichologinis vystymasis. Šių procesų veiklai labai svarbi tinkama mityba, o minėti procesai sąlygoja vaiko maitinimą, valgymą bei vykstančius procesus, kai organizmas gauna maisto medžiagas. Viena iš būtiniausių maisto produktų grupių mitybos požiūriu – pienas ir jo produktai. Lietuvos rinkoje prekiaujama pieno mišiniais vaikams nuo vienerių metų. Remiantis EFSA ir ESPGHAN gairėmis, pieno mišiniai, sulaukus vienerių metų, turėtų būti vadinami „jaunesniems vaikams pritaikytu pienu“ [1, 2].

Feministická muzeologie: Výběr současných světových trendů
Authors: Krutílková Hana
Published: November 2022

The paper provides a basic overview of the hitherto little-known scientific discipline in the Czech lands, namely feminist museology, and its related field – gender theory – in connection with museology. The study places the aforementioned perspectives in a broader world trend, which is understood as the new museology. It presents basic possible approaches and application of theoretical knowledge to the practice of historical museums, including the creation of „women‘s collections“, the establishment of „women‘s museums“, reflection on the phenomenon #MeToo , gender audits of exhibits and the professional structure of museums. Equally important are the calls for the equality of women visitors and employees of memory institutions, the visibility of various social groups, including women, and the so-called problematic topics in the narrative of museums. The paper also presents the activities of The International Association of Women‘s Museums.

This work aimed to study the accessibility and use of educational technology for teaching mathematics in senior secondary schools in Delta State. Descriptive survey design was used in the work. 60 mathematics teachers in 30 secondary schools were the sample of the work; simple random technique was used to select them from the overall population of 75 secondary schools in Delta State. Two teachers’ questionnaire titled use and preventing factors mathematics questionnaire (r =0.77) were utilized to collect data. Simple percentage, mean and standard deviation were used to analyze the data. The findings showed that there were laboratory equipment and audio educational technology but were not fully used; there were no audio visual technologies and were not used to teach mathematics. Also, lack of money, poor application law, demotivation etc prevented the delivery and use of educational materials for mathematics teaching. The study gave the recommendation that Mathematics teachers should use the educational technology that is available and government should provide enough money to procure educational technology.
University Mathematics Major Students’ Ratings of Their Lecturers’ Preferred Teaching Methods: A Repeated-Measures Design
Authors: Assuah Charles Kojo , Oseia Louis , Manteya Gershon Kwame
Published: November 2022

This study investigates the differences in lecturers’ preferred teaching methods based on the ratings of their students. It employed the repeated measures design, where four separate ratings for each participant were taken. The participants comprise eighty-two (82) university mathematics major students, made up of fifty-five (55) males and twenty-seven (27) females, who were selected from a university in the central region of Ghana, using a non-proportionate stratified sampling technique in two third-year cohort mathematics classes. The results indicated that Mauchly’s test of sphericity was not significant, χ^2 (5)=10.33,p>.05, (i.e., the assumption about the characteristics of the variance-covariance matrix was not violated). Thus, the within-subjects variable of the teaching method was highly significant, F (3, 243) = 468.17, p < .05, indicating that the mean students’ ratings differed significantly as a function of the four teaching methods. This was supported by the decrease in the mean students’ ratings from guided discovery to direct instruction methods. The pairwise comparisons (with Bonferroni adjustment) among the four teaching methods, showed a significant difference between any pair of teaching methods (p < .05). Thus, the students’ ratings for guided discovery were higher than the ratings for cooperative learning (p < .05), ratings for cooperative learning were higher than the ratings for inquiry-based learning (p < .05), and the ratings for inquiry-based learning were higher than the ratings for direct instruction (p < .05). The estimated marginal means for the ratings of guided discovery (M = 8.12; C. I = [7.94, 8.32]) were the highest, followed by the mean ratings for cooperative learning method (M = 6.68; C.I = [6.51, 6.86]), followed by the mean ratings for inquiry-based learning (M = 4 73; C. I = [4.60, 4.87]), and then followed by the mean ratings for direct instruction (M = 3.95; C.I = [3.80,4.11]). The study's implications are that, although many researchers recommend multiple teaching methods for mathematics instruction, lecturers should endeavour to use teaching methods that are popular and acceptable among students. This would enable them to understand the content their lecturers teach. The study concludes that lecturers should focus more on active teaching methods such as guided discovery and cooperative learning and focus less on the direct instruction teaching method.

Published: November 2022

Recently, therapeutic applications of modified magnetic nanoparticles have attracted the attention of many researchers. The reason is the ability to develop nano drugs as cancer treatment agents. For this purpose, these particles must have a tiny size, intrinsic magnetic properties, imaging effectiveness, the ability to target the drug, and high drug absorption. Although studies have been performed on the anti-cancer properties of curcumin/nanoparticles, no comprehensive research has been performed to evaluate its anti-cancer and the normal cell toxicity of this drug system for breast cancer treatment. This study designed a curcumin-loaded MNPs (MNPs@CUR) formulation to accomplish these unique features. Using the diffusion process, chemical precipitation was used to make MNPs, which were then loaded with curcumin (CUR). Transmission electron microscopy (TEM) was used to study the morphology and size of MNP-CUR. The fabricated MNPs had spherical shapes with an average length of 23.22 nm. The presence of curcumin on the surface of MNPs was approved using Fourier transform infrared (FTIR) analysis. The X-ray diffraction (XRD) diffractogram confirmed the face cubic center (fcc) character of MNPs.  After 24 hours of incubation with 4t1 breast cancer cells, MNPs@CUR anticancer effects were evaluated. MNPs@CUR displayed a concentration-dependent preference for applying anticancer effects on 4t1cells (IC50=108 µg/ml).  Separated in vivo anti-tumor studies of coated/naked nanoparticles and curcumin also demonstrated that MNPs@CUR eliminated tumor mass. The cytotoxicity and genotoxicity against normal peripheral blood mononuclear cells (PBMC) were also measured by 2,5-diphenyl-2H-tetrazolium bromide (MTT) electrophoresis DNA digestion methods respectively for MNPs@CUR and naked MNPs. Cytotoxicity was demonstrated at high concentrations of MNP@CUR (991 µg/ml), while naked nanoparticles showed approximately no toxicity and neither had genotoxicity.

A COMPOSITE COLLOCATION METHOD BASED ON THE FRACTIONAL CHELYSHKOV WAVELETS FOR DISTRIBUTED-ORDER FRACTIONAL MOBILE-IMMOBILE ADVECTION-DISPERSION EQUATION
Authors: Marasi Hamidreza , Derakhshan Mohammadhossein
Published: November 2022

In this study, an accurate and efficient composite collocation method based on the fractional order Chelyshkov wavelets is proposed for obtaining approximate solution of distributed-order fractional mobile-immobile advection-dispersion equation with initial and boundary conditions. Operational matrices based on the fractional Chelyshkov wavelets are constructed. The proposed method reduce the solution to a system of algebraic equations, which is solved by Newton’s iterative method. Provided examples confirm the accuracy and applicability of the proposed method in line with the studied convergence analysis and error estimation. The obtained results of demonstrated numerical schemes illustrate that this approach is very accurate and efficient.
Two Example GRBs Where Fermi LAT “Extended” Data Gives a Better Photon List than “Photon”
Authors: Aldrich E. Casey , Mukherjee Oindabi , Nemiroff Robert J.
Published: November 2022

When analyzing Fermi LAT data for temporally contained events like gamma-ray bursts (GRBs), the best data type for analyses is “Extended,” not “Photon.” Although this is already recommended by the online Fermi website, it is easy to overlook and can lead to inferior analyses. Most extended “events” that are temporally and angularly consistent with GRBs are probably photons. While preparing GRB data for other research projects, the authors encountered this counter-intuitive fact several times. The data from two GRBs are presented with a simple analysis as a demonstration.
Complementary Mass Spectral Analysis of Isomeric O-bearing Organic Compounds and Fragmentation Differences through Analog Techniques for Spaceborne Mass Spectrometers

Published: November 2022

Mass spectrometers on board spacecraft typically use either impact ionization or electron ionization (EI) as ion sources. Understanding the similarities and differences in the spectral signatures and fragmentation patterns produced by different techniques in mass spectrometry could elucidate the composition of organic compounds. Here we present a comparison between the mass spectra obtained through laser-induced liquid beam ion desorption (LILBID; proven to simulate the impact ionization mass spectra of ice grains) and EI mass spectra of pairs of low-mass, isomeric aldehydes and ketones. Our comparison confirms that EI produces more fragmentation of carbonyl compounds, particularly aldehydes, than LILBID. We find protonated molecular ions [M+H]+ in LILBID but molecular ions [M]+ in EI spectra. From the evaluated species, LILBID generally produces oxygen-carrying fragment ions (e.g., [CHO]+ and [C2H3O]+) in the mass ranges 26–30 and 39–44 u, while in EI, most ions in these ranges correspond to hydrocarbon fragments. The LILBID spectra additionally show mostly protonated oxygen-bearing fragments [CH3O]+ and [C2H5O]+ at m/z 31 and 45, less commonly observed in EI spectra. We observe a decrease in the relative intensities of cation fragment mass lines between m/z 26 and 33 and an increase between m/z 39 and 45, with an increasing carbon number for ketones and aldehydes with LILBID and EI, respectively. Our study provides a basis for complementary compositional analysis to identify the structural properties of organic species in a space environment using different spaceborne mass spectrometers (e.g., SUrface Dust Analyzer and MAss Spectrometer for Planetary EXploration) on board NASA’s future Europa Clipper space mission.
The impacts of the invasive lionfish on Caribbean food webs
Authors: Cameron Courtney , Roopnarine Peter D.
Published: November 2022

Increased rates of species extirpation or extinction have often been attributed to the foraging behavior of invasive predators, with drastic effects on native food webs. In the Caribbean, the invasive red lionfish (Pterois volitans) is of primary concern, as it reduces the overall recruitment and biomass of reef fishes by as much as 80% and 65%, respectively. Understanding the functional role that this predator plays in the context of entire communities is critical to assessing how it impacts those that have already experienced regime shifts due to disturbance. Here, a trait-based ecospace was employed to characterize the functional role of red lionfish trophic behavior, focusing on a regional pool of reef fishes from Jamaica, Cuba, and the Cayman Islands. A high-resolution model of a Greater Antilles coral reef food web, including micro- and macrobiota, producers and consumers, and invertebrates and vertebrates, was used to assess the impacts of P. volitans on community structural parameters such as food chain length, the number of interactions, modularity, and trophic position. Results indicate that lionfish select prey based on specific traits, foraging primarily on those that are diurnal, below a threshold of total length, occur higher in the water column, do not possess a physical defense, and are either herbivorous, invertivorous, or omnivorous. The functional role of lionfish significantly overlaps with a number of endemic high trophic level predators, such as Rhizoprionodon porosus, Negaprion brevirostris, and Scomberomorus regalis. Lionfish could be fulfilling trophic roles previously vacated by extirpated species, as the prey of the lionfish were found to be functionally indiscriminate relative to those of extirpated predators such as Sphyrna tiburo, Carcharhinus acronotus, and Galeocerdo cuvier. In addition, food web results suggest that lionfish alter the trophic dynamics of the entire reef community by increasing the total number of interactions and changing trophic level structure. Interestingly, the invasive lionfish may be restoring and augmenting some effects of predation otherwise lost to species extirpation, providing an alternative view to its detrimental effects on resilience of Caribbean marine systems.
An assessment of local community engagement in wildlife conservation: a case study of the Save Valley Conservancy, South Eastern Zimbabwe

Published: November 2022

In Southern Africa, human and wildlife interactions have significantly increased over the past decade resulting in complex conservation conflicts. For instance, conservation conflicts in the Save Valley Conservancy (SVC) in the southeast lowveld of Zimbabwe have grown to a level of drawing the concerns of various players, both within and outside the protected area. However, these players are of diverse opinions and interests calling for an inclusive, effective and multi-integrated stakeholder engagement strategy that addresses these needs and opinions in a transformative conservation framework. As humans and wildlife share space, stakeholder engagement becomes a critical component of wildlife management and transformative conservation. In this study, we analysed the conservation conflicts in the SVC. Data were collected between April and May 2020 through focus group discussions and interviews with 20 key purposively sampled informants. This study results revealed a lack of an effective, inclusive, integrated multi-cross-sectional stakeholder engagement plan as one of the major contributing factors to the existence of conservation conflicts in the SVC. It is concluded that, there is limited participation by community members and generally no shared views among the community members on viable land use options in the SVC. This study proposes for an integrated cross-sectional stakeholder working framework which does not only inform conservation practitioners but also fully addresses the prevailing conservation conflict scenarios emanating from the exclusion of humans from protected areas and the encroachment of wildlife in human settlements.
Transcranial Direct Current Stimulation (tDCS) for Major Depressive Disorder
Authors: Gersten Maia , Jamil Asif , Cassano Paolo , Camprodon Joan A.
Published: November 2022

Of all home-based and wearable neuromodulation techniques currently in use for treatment of major depressive disorder (MDD), transcranial direct current stimulation (tDCS) has the greatest evidence and efficacy for antidepressant response. The potential of tDCS, given that it is safe, low-cost, portable, and easy to use, is promising. We review clinical trials and meta-analyses on the efficacy of tDCS for MDD, and discuss standard protocols, safety, and side effects. The use of tDCS in bipolar disorder is also explored. Clinicians should fully understand their patient's profile before recommending tDCS, as certain medications, depression subtypes, and age can influence treatment planning and response.

Topical Losartan for Treating Corneal Fibrosis (Haze): First Clinical Experience
Authors: Pereira-Souza Amanda Luiza , Ambrósio Renato , Bandeira Francisco , Salomão Marcella Q. , Souza Lima Acacio , Wilson Steven E.
Published: November 2022

PURPOSE:

To report the first clinical experience with topical losartan for treating a case of severe corneal haze after complicated laser in situ keratomileusis (LASIK).

METHODS:

A 36-year-old woman presented with corneal haze in the left eye after femtosecond laser–assisted LASIK. The left eye had flap dislocation and significant striae, which had been re-lifted. Uncorrected distance visual acuity (UDVA) was 20/200 and corrected distance visual acuity was 20/30 in the left eye at the first presentation, 52 days after the first procedure. A dense layer of subepithelial opacity (haze) was noted in the left cornea. The patient elected to start the off-label treatment with topical losartan 0.8 mg/mL six times per day.

RESULTS:

Four and one-half months after initiating topical losartan, UDVA improved to 20/30 and CDVA improved to 20/25 in the left eye. A significant reduction of corneal haze was observed at the slit lamp and using Scheimpflug corneal tomography (Pentacam AXL; Oculus Optikgeräte GmbH) and anterior segment optical coherence tomography (Revo NX 130; Optopol).

CONCLUSIONS:

Losartan is an inhibitor of transforming growth factor-β signaling. Topical treatment is promising to treat corneal haze formation after corneal injuries, chemical burns, and surgeries. Further clinical studies are needed to optimize losartan dosages and treatment durations.

A new approach to generalized interpolative proximal contractions in non archimedean fuzzy metric spaces
Authors: Javed Khalil , Nazam Muhammad , Jahangeer Fahad , Arshad Muhammad , Sen Manuel De La
Published: November 2022

We introduce a new type of interpolative proximal contractive condition that ensures the existence of the best proximity points of fuzzy mappings in the complete non-archimedean fuzzy metric spaces. We establish certain best proximity point theorems for such proximal contractions. We improve and generalize the fuzzy proximal contractions by introducing fuzzy proximal interpolative contractions. The obtained results improve and generalize the best proximity point theorems published in Fuzzy Information and Engineering, 5 (2013), 417–429. Moreover, we provide many nontrivial examples to validate our best proximity point theorem.
Data-driven two-stage sparse distributionally robust risk optimization model for location allocation problems under uncertain environment
Authors: Liu Zhimin
Published: November 2022

Robust optimization is a new modeling method to study uncertain optimization problems, which is to find a solution with good performance for all implementations of uncertain input. This paper studies the optimal location allocation of processing plants and distribution centers in uncertain supply chain networks under the worst case. Considering the uncertainty of the supply chain and the risk brought by the uncertainty, a data-driven two-stage sparse distributionally robust risk mixed integer optimization model is established. Based on the complexity of the model, a distribution-separation hybrid particle swarm optimization algorithm (DS-HPSO) is proposed to solve the model, so as to obtain the optimal location allocation scheme and the maximum expected return under the worst case. Then, taking the fresh-food supply chain under the COVID-19 as an example, the impact of uncertainty on location allocation is studied. This paper compares the data-driven two-stage sparse distributionally robust risk mixed integer optimization model with the two-stage sparse risk optimization model, and the data results show the robustness of this model. Moreover, this paper also discusses the impact of different risk weight on decision-making. Different decision makers can choose different risk weight and obtain corresponding benefits and optimal decisions. In addition, the DS-HPSO is compared with distribution-separation hybrid genetic algorithm and distributionally robust L-shaped method to verify the effectiveness of the algorithm.
Travail du laiton et production de mforowa parmi les Akan de la côte du Ghana du xviie au xxe siècle
Authors: DeCorse Christopher R.
Published: November 2022

Cet article traite de la fabrication et de la datation des ornements, outils et boites en laiton produits par les Akan dans les régions côtières du Ghana, en particulier les mforowa (sing. forowa), récipients en feuilles de laiton spécifiques utilisés pour y conserver le beurre de karité et qui sont associés à des rituels mortuaires. Les fouilles archéologiques ont permis de retrouver une variété d’artefacts fabriqués localement à partir de laiton européen importé, souvent en étroite association avec des objets de traite européens. Comme les gammes de production de nombreuses manufactures européennes sont connues et peuvent être bien circonscrites dans le temps – souvent à quelques décennies près –, les marchandises de traite offrent un moyen de dater précisément les artefacts qui leur sont associés et de manière plus assurée que ce qui est souvent possible pour les sites archéologiques africains des 500 dernières années. Cet affinage chronologique apporte un élément nouveau sur les traditions de travail des alliages de cuivre parmi les Akan côtiers, en particulier l’utilisation et la réutilisation du laiton importé. Cet article passe en revue les connaissances actuelles sur les origines de la métallurgie et la transformation du métal dans la région côtière du Ghana, et sur le développement du travail du laiton avec l’avènement du commerce européen. Les données archéologiques provenant de la ville africaine d’Elmina suggèrent que la production de mforowa a débuté au xviie siècle et que ses origines stylistiques trouvent leurs racines dans la tradition antérieure des nkuduo (sing. kuduo) en laiton coulé. Le contexte des découvertes archéologiques fournit également un aperçu des cadres culturels dans lesquels les mforowa ont été utilisés.
Deux millénaires ou deux siècles de constructions mégalithiques au Sénégal et en Gambie ? Nouvelles dates pour Wanar et révision des contextes archéologiques

Published: November 2022

Les mégalithes du Sénégal et de la Gambie comptent près de 30 000 pierres dressées qui ont été répertoriées sur une superficie d’environ 30 000 km². La toute première date radiocarbone associée aux mégalithes du Sénégal et de la Gambie a été publiée en 1965. La plupart des dates radiocarbone obtenues depuis lors concernent la partie la plus occidentale du mégalithisme sénégambien. Plus de 28 dates supplémentaires, pour la seule nécropole de Wanar (Sénégal), peuvent désormais être ajoutées aux 25 dates précédemment disponibles. Des modèles bayésiens, intégrant les contraintes stratigraphiques propres à chaque séquence pour chacun des monuments étudiés, indépendamment les uns des autres, nous permettent de préciser ces données, et de proposer un scénario historique. Elles illustrent une séquence régionale de peuplement sur plus de deux millénaires, alors que la construction des cercles de pierres dressées pourrait ne pas avoir duré plus de 200 à 300 ans. Deux dates radiocarbone sur des dents humaines fixent le décès des personnes inhumées au cours des xie ou xiie siècles AD.
Panal que cela su oro: (auto)censura, traducción, cartas y versos de amor de Gabriela Mistral a Doris Dana y a Paulita Brook
Authors: Madrigal Elena , Bermúdez Callejas Sulemi
Published: November 2022

A partir de una lectura feminista y queer, analizamos diversos ethos escriturales de Gabriela Mistral, que se presentan en tres instancias: sus diarios, el epistolario amoroso que sostuvo con Doris Dana y el poema “La dichosa”, dedicado a Paulita Brook. Este acercamiento revela un yo multifacético, oscilante entre su prestigio público y un lesbianismo en consecuencia disidente, alejado del escándalo. En consonancia con los nuevos estudios mistralianos, proponemos tres perspectivas para el estudio de su ethos: su configuración icónica como defensora de los derechos de las mujeres, el fenómeno de la (auto) censura, así como la relectura de una composición poética. Al sumar algunos hitos biográficos y detalles contextuales, sostenemos que la admisión de la orientación sexual de Mistral posibilita interpretar sus escritos de manera novedosa así como entender la parcialidad de las traducciones de su obra al inglés y la tardía publicación de su obra completa, a contracorriente de la insistencia aún vigente de interpretaciones reduccionistas.
Students' Views on the Benefits of E-Learning During the COVID-19 Pandemic and the Factors That Facilitated Their Learning
Authors: Korres Maria Pavlis
Published: November 2022

The transition from face-to-face to synchronous online learning during the COVID-19 pandemic has been a major challenge for everyone involved – both educators and learners. This chapter explores the views of students from the Aristotle University of Thessaloniki's School of Early Childhood Education on the advantages of synchronous e-learning and the factors that facilitated their learning in both synchronous classes and asynchronous learning sessions during the COVID-19 pandemic era. The study presents the results of a qualitative research that involved 129 students. Among the main advantages of synchronous e-learning cited by students are the ability to participate in the learning process safely, the ease of access, and time and cost effectiveness resulting from reduced commuting activity. Upon discussing the factors that facilitated their learning, students highlighted those that promoted student-centered learning, interaction between participants, and emphasized the role of the instructor and the convenience of attending from home.
Barriers to the Implementation of Social Emotional Learning Programs
Authors: Akelaitis Arturas , Janiunaite Brigita
Published: November 2022

The main research question of this chapter focusses on what peculiarities and especially barriers occur when teachers implement social emotional learning (SEL) programs in urban and rural school settings. First, this study defines SEL and introduces core social emotional competencies, explores the concept of barriers, and presents their classification. Second, the justification of the research methodology and instrument is performed. Third, the results of a quantitative study using a written survey of teachers (N=619) from different urban and rural school settings in Lithuania as well as possible solutions to reduce barriers and recommendations are presented. The present study revealed that barriers, such as students' attitudes toward SEL, resources (financial, time, and material), training and guidance, teachers' emotional well-being, and acceptance of change were predominant in the implementation of SEL programs by teachers in Lithuanian schools. The success of the implementation of SEL programs also depends on the school location and sociodemographic characteristics of teachers.
