Authors: Rajaswi Devi M. , Gnaneswari K. , Padma K.R. , Apparao CH. , Potireddy Suvarnalatha Devi
Published: May 2023

The in vitro anti-diabetic effect of a methanolic extract of C. benghalensis was examined through suppression of enzymes that break down carbohydrates. Compared to the common enzyme inhibitor Acarbose, the crude extracts of C. benghalensis both α -glucosidase and α -amylase were severely inhibited. The anti-diabetic efficacy was discovered to rely on concentration and the anti-hyperglycemic activity was shown by the inhibition of glucose movement and enhanced glucose diffusion. From 30 to 180 minutes, the rate of glucose dispersion across the membrane increased. In light of the results, C. benghalensis considerably decreased postprandial hyperglycemia by inhibiting the flow of glucose and the enzymes that break down carbohydrates.

Authors: Alsouz Mohammed A.K. , Al-jibouri Mahmoud Najim
Published: May 2023

The chelation behavior of azo dye HL derived from coupling 4-nitrophenyl diazonium salt with 7-hydroxycoumarin with Cd (II), Hg(II) and Fe (III) metal ions has been studied. Reaction of the azo dye with Cd (II) and Hg(II) ions at different pH gave new two complexes. At pH=8, complex of the formula [Cd(L)2]Cl2 was formed while at pH=4.5, the complex [Cd(L) Cl2]. 2H2O was obtained. Another two new complexes of the formula [Fe(L)2Cl2]Cl.2H2O have been obtained from the reaction of aqueous solution of the azo dye with FeCl3.6H2O. All the above preparations were performed after fixing the optimum pH and molar concentration. Wide range of molar concentrations was investigated and the concentration which obeyed the Lambert-Beer’s Law, was chosen. The effects of time on the stability of these complexes were checked. The stoichiometry of the above prepared complexes was determined using mole ratio and Job methods. A great bathochromic shift was observed in the UV–Vis absorption spectra of (10-6-10-8 mole/lit.) of an aqueous solution of the solid complexes. The vibration spectra of these complexes gave different changes compared to that of the free ligand. The 1H NMR spectra for one of the complexes were also performed.

Authors: Konale Ram , Mahale Nilesh , Kedar Pradnya , Ingle Sopan
Published: May 2023

The higher concentrations of nitrate, sulphate and phosphate (NSP) are leading to eutrophication in water bodies. It is very essential to control the inflow of these eutrophication nutrients to avoid eutrophication of water bodies. In the present study investigation, nano-zeolites are synthesized using fly ash via hydrothermal route for simultaneous removal of nutrients from the industrial wastewater. The crystallographic and morphological studies by FE-SEM, XRD and FTIR confirm the formation of nano-zeolites. The effect of adsorption parameters on nitrate, sulphate and phosphate (NSP) was studied by the batch adsorption process. The equilibrium time was 70 min for nitrate and 90 min for sulphate and phosphate. The maximum adsorption occurred at neutral pH and adsorbent dose 800 mg/L. The R2 values for the pseudo-second-order equation for the adsorption process were 0.994, 0.996 and 0.998 for nitrate, sulphate and phosphate respectively. The exothermic reaction between adsorbent and adsorbate was indicated as the adsorption study obeys the Langmuir isotherm. The effective removal of NSP by nano-zeolite demonstrates a great potential for industrial and domestic sewage wastewater treatment. The application of this technology to the waste-carrying nutrients will help to avoid the eutrophication of natural water resources.

Published: May 2023

The purpose of this study was to evaluate the effect of rapid weight loss on static balance and functional mobility among excessively obese patients undergoing Laparoscopic Adjustable Gastric Banding (LAGB) surgery. Subjects (8 females; BMI >35 kg/m2) underwent baseline measurements before LAGB surgery, followed by subsequent evaluations at 6 weeks, 12 weeks, and 24 weeks during the follow-up appointments. During each evaluation, various assessments were conducted, including measurements of anthropometry such as body weight, height, hip and waist circumference, as well as functional tests for static balance, 10-meter walk, and timed get-up-and-go. There were statistically significant changes in weight, BMI, waist circumference, hip circumference, abdominal circumference, waist-hip ratio, static sway eyes open, timed up-and-go, 10-meter walk, and steps in 10-meter walk test values (p<0.001) between the baseline and the postoperative measurements. However static sway values under eyes closed condition were not statistically significant. In the 24-week follow-up, the weight loss, reduction in abdominal circumference, increase in walking speed against time and step count, and recovery in functional movements were shown to persist. Also, reduction in static balance surface oscillation confirmed the improvement of balance control.
Understanding chiral proton organocatalysis using cinchonium derivatives
Authors: Auria-Luna Fernando , Marqués-López Eugenia , Gimeno M. Concepción , Alegre-Requena Juan V. , P. Herrera Raquel
Published: May 2023

This work presents a detailed mechanistic study of a quininium-catalyzed aza-Michael reaction, providing essential infor-mation for the development of reactions in chiral proton organocatalysis (CPO). The use of cinchona derivatives as chiral proton catalysts demonstrates their potential beyond their conventional roles as base-promoted and phase-transfer cata-lysts. Competitive reaction pathways are studied using density functional theory (DFT), wavefunction theory, and microki-netic simulations. Additionally, theoretical studies are complemented with experimental titration and kinetic techniques to verify the intrinsic details of the reaction. The mechanistic study reveals a complex hydrogen bond network formed in the rate- and selectivity-determining step (hydrazide addition), involving four noncovalently attached components that favor a more efficient substrate docking in the R transition state. Notably, while counteranions are often considered innocent reac-tion components, carboxylic anions are crucial in understanding reaction yield and enantioselectivity, as they act as nucleo-phile-activating bases. Overall, this study introduces cinchonium derivatives as new options for CPO and provides a thor-ough mechanistic analysis that may be critical in expanding this underdeveloped type of catalysis.

Metal-free electrocatalysts for oxygen evolution reaction (OER) are crucial to enable practical water splitting for future clean energy production. The preparation of such electrocatalysts remains a great challenge because they are difficult to obtain a high energy input due to the limitations of kinetically sluggish anodic half-cell reaction. Herein, we develop a novel metal- and pyrolysis-free ionic covalent organic framework (COF) nanosheet (termed JUC-627-NS) and explore its application as an efficient OER electrocatalyst for the first time. Remarkably, the samples combined with JUC-627-NS and graphene can obtain an ultralow overpotential (275 mV at a current density of 10 mA cm-2), which is one of the best among metal- and pyrolysis-free electrocatalysts reported so far. Combining theoretical calculations and in-situ infrared spectroscopy, it is proved that the imidazolium salt moiety is the active center of the electrocatalyst, and the strong cation-π interaction in the complex greatly promotes the reactivity. These results therefore provide a new strategy for designing ionic COF nanosheets as efficient metal-free OER electrocatalysts for energy conversion and storage devices.
Revolutionizing Phenotypic Antimicrobial Susceptibility Testing: Lightning-Fast Techniques Based on Cutting-Edge Electrochemistry
Authors: R Pragadeeshwara Rao
Published: May 2023

Due to the ongoing concern for the development of rapid and accurate antimicrobial susceptibility testing (AST) methods in the field of clinical microbiology, several novel AST systems have been developed to replace the traditional gold standard AST techniques, which are time-consuming and can lead to delayed susceptibility guided therapy outcomes. In this review, the focus is on the phenotypic assays based on electrochemistry that are used to determine bacterial susceptibility towards antibiotics. Electrochemical techniques have gained significant interest in the field of AST due to their rapidity, sensitivity, and specificity, although it is important to note that some of these methods may have limitations regarding the specific classes of antibiotics and bacteria that they can be applied to, which researchers can address by fine-tuning the techniques or incorporating additional controls. By offering significant advantages over traditional AST methods in terms of rapidity and accuracy, electrochemical phenotypic assays could lead to improved patient outcomes.

Published: May 2023

Low-valent main group element compounds are typically air and moisture sensitive. Using these compounds as organic transfor-mation catalysts needs that the reactions be carried out under inert conditions. Given the growing demand for simple chemical pro-cesses, we looked for strategies that could be used to carry out these reactions simply under ambient lab conditions. We were able to accomplish this by employing an air and water stable germylene cation ([DPMGe][(HO)B(C6F5)3] (2). The dipyrrinate (DPM) ligand stabilized compound 2 catalyzes aldehyde and ketone hydrosilylations under ambient conditions.
1H NMR metabolic profiling for the differentiation of fish species
Authors: Saglam Melike , Paasch Nele , Horns Anna Lena , Weidner Markus , Bachmann René
Published: May 2023

The determination of fish species is an important task for food control, especially in the case of very similar and processed fish or fish products. Typically, this analysis is carried out by DNA-based methods. However, especially for small sample series the effort for sample preparation and the required analysis time are not satisfactory. We show that by means of a simple extraction and analysis of the 1H NMR spectra of these extracts a fast discrimination of fish species is possible. For this purpose, 69 samples consisting of five sample groups iridescent shark, European plaice, rock sole, witch flounder and common sole were analysed. The large differences in the 1H spectra could be further highlighted with a principal component and led already to a graphical differentiation of most sample groups. The performed classification of the samples using a subspace discriminant algorithm showed a recognition rate of 100% for all samples, regardless of additives like citric acid or lysine. These results show that 1H NMR spectroscopy is a robust, simple and rapid method for the recognition of the fish species studied.
Formulation of a Target Plastic Model to estimate critical plastic burdens of toxicants.
Authors: Nabi Deedar , Beck Aaron J. , Achterberg Eric P.
Published: May 2023

Plastic pollution has become a widespread problem affecting multiple environmental compartments, with associated chemicals having harmful effects on living organisms. Here, we developed a Target Plastic Model (TPM) to estimate the critical plastic burden of various toxicants in five types of plastics, namely polydimethylsiloxane (PDMS), polyoxymethylene (POM), polyacrylate (PA), low-density polyethylene (LDPE), and polyurethane ester (PU), following the Target Lipid Model (TLM) framework. The critical plastic burdens of baseline (n=115), less-inert (n=73), and reactive (n=75) toxicants ranged from 0.17-51.33, 0.04-26.62, and 1.00 × 10^-6 - 6.78 × 10^-4 mmol/kg of plastic, respectively. While critical plastic burdens were also estimated for other plastic phases, such as polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), ultra-high molecular weight polyethylene (UHMWPE), and high-density polyethylene (HDPE), the findings were less reliable due to a lack of experimental data. Our study showed that PDMS, PA, POM, PE, and PU are similar to biomembranes in mimicking the exchange of chemicals with the water phase. Using the TPM, median lethal concentration (LC50) values for fish exposed to baseline toxicants were predicted, and the results agreed with experimental values, with RMSE ranging from 0.311-0.538 log unit. For less inert chemicals, predictions were within a factor of 5 of experimental values. The TPM's performance was comparable to other widely used models, such as the TLM, ECOSAR, and Abraham Solvation Model. However, like other models, TPM was not effective in predicting the toxicities of reactive toxicants, with RMSE exceeding 1 log unit. TPM can provide valuable insights into the toxicities of chemicals associated with environmental plastic phases, assisting in selecting the best polymeric phase for passive sampling and designing better passive dosing techniques for toxicity experiments. Moreover, TPM can assist in selecting the best plastic phase for developing animal alternatives for toxicity measurement and determining the toxicity of complex mixtures such as those arising during oil spills.
Identifying Underexplored and Untapped Regions in the Chemical Space of Transition Metal Complexes
Authors: Nandy Aditya , Taylor Michael , Kulik Heather
Published: May 2023

We survey over 230,000 crystallized mononuclear transition metal complexes (TMCs) to identify trends in preferred geometric structure and metal coordination. While we observe d-filling to influence coordination preference, with late TMCs preferring lower coordination number, we also note exceptions. We also observe that 4d and 5d transition metals and 3p-coordinating ligands are systematically undersampled. For the roughly one third of the set of mononuclear TMCs that are octahedral, analysis of the 67 symmetry classes of their ligand environments reveals that complexes most commonly contain monodentate ligands that may likely be removable to leave an open site amenable to catalysis. Due to their frequent use in transition metal catalysts, we analyze trends in coordination by tetradentate ligands in terms of the capacity to support multiple metals and the variability of coordination geometry. We identify promising tetradentate ligands that co-occur in crystallized complexes with labile monodentate ligands, indicating their ability to generate reactive sites. Literature mining suggests that many of these tetradentate ligands are untapped as ligands in catalytic complexes, motivating proposal of a promising octa-functionalized porphyrin in this set as a candidate ligand for catalysis.
Enantioselective radical cascade cyclization via Ti-catalyzed redox relay
Authors: Yu Peng , Zhang Wen , Lin Song
Published: May 2023

Radical cascade cyclization reactions provide an efficient method for the construction of polycyclic architectures with multiple stereogenic centers. However, achieving enantioselectivity control of this type of reaction is a challenging task. Here, we report an enantioselective cyclization of polyfunctional substrates containing cyclopropyl ketone and alkyne units, wherein the stereochemical outcome is directed by a chiral Ti(salen) catalyst. This transformation was proposed to proceed via a radical cascade process involving the reductive ring-opening of the cyclopropyl ketone followed by two annulation events entailing cyclization of the ensuing alkyl radical onto the alkyne and subsequent addition of the incipient vinyl radical to the Ti(IV)-enolate.

Eggs are livestock products that have a big contribution in overcoming nutritional problems in society. Generally, eggs only last for two weeks if stored at room temperature. Therefore preservation efforts are very important to maintain the quality of the eggs, so that the quality and nutritional value of the eggs remain good and do not change the taste, smell, color and contents. One way is to preserve them by salting and adding red ginger. Red ginger contains antioxidants, antimicrobials and essential oils that can preserve and give a distinctive aroma. The aim of this study was to determine the effect of adding red ginger (Zingiber officinale Rubrum variety) on the characteristics of salted eggs. The study used a completely randomized design (CRD) with 5 treatments, namely P0: 0% red ginger, P1: 20% red ginger, P2: 30% red ginger, P3: 40% red ginger, and P4: 50% red ginger with 5 times test. The results showed that the characteristics of salted eggs with the addition of 30% red ginger got the highest score in the hedonic method organoleptic test.

Authors: Zhydkova Viktoria Viktorivna , Polishchuk Iryna Romanivna
Published: May 2023

It has been established that the costs of overburden are the costs of open mining operations associated with improving access to the mineral and the ability to separate it from the rock. They include the preparation of rock for extraction by means of blasting, the extraction and loading of rock, their movement and the formation of dumps. The classification of costs for excavation works during the extraction of minerals in granite quarries for accounting purposes has been developed: by economic elements; by the period of recognition as part of expenses; depending on the stage of the life cycle of the technological process of mineral extraction; depending on the subject of performance; according to the degree of completeness of the distribution between reserves and the asset of excavation work; according to the results obtained as a result of their implementation; by capitalization level; based on the results of a comparison of costs for excavation works and the benefits received and the possibility of including costs in the value of assets. An algorithm has been developed for the recognition of costs for overburden work at the mining stage as an asset in accordance with the Interpretation of IFRIC 20 «Expenses for overburden work at the mining stage in a quarry». The content and characteristics of cost items for excavation work in preparatory works for granite extraction in deposits are disclosed in accordance with Appendix No. 1 to the Standard Regulation on planning, accounting and costing of products (works, services in industry) «Nomenclature of cost items for preparatory work in mining industries». It has been established that the main normative documents governing the exploration and estimation of mineral reserves are IFRS 6 «Exploration and estimation of mineral reserves» and National Accounting Regulation (standard) 33 «Expenses for the exploration of mineral reserves». The recognition of costs for excavation works as part of reserves and non-current tangible and intangible assets is characterized, regulated by the Interpretation of IFRIC 20 «Expenses for excavation works at the mining stage in a quarry».
Sociolinguistic Pedagogical Implications of EFL Issues: A Case Study of Saudi Universities
Authors: Elmahidi Omer Elsheikh Hago , Abd Algane Mohammed , Bajri Ibtesam Abdul Aziz
Published: May 2023

In this study, the sociolinguistic pedagogical implications of English as a Foreign Language (EFL) issues in Saudi universities have been considered. Future EFL instructors require education that acknowledges linguistic, socio-historical, cultural, and pedagogical aspects. Areas of improvement in explaining instructors' vital role in changing language education are highly concentrated in language proficiency and technology. Investigating in the significant influence of sociolinguistic characteristics on the educational context and the growth and use of EFL results in raising social and cultural awareness, enabling students to know how to interpret the surrounding environment. In this study report, we describe the close relationship between social and educational settings, and the classroom environment as suitable factors for fostering sociolinguistic competence in EFL learners. The desired outcomes were to explore whether culture and education could be viewed as two inseparable independent parameters and whether EFL learners needed to master the cultural rules of use and rules of discourse. EFL instructors believe that teaching a language in its natural context is the best way to teach the language. The authors used a questionnaire to collect data from Saudi university staff members. A significant conclusion was reached about the sociolinguistic pedagogical implications of EFL issues. Responses to the questionnaire were analysed by SPSS. The use of a socio-pedagogical approach to teaching EFL can have a positive impact on EFL issues. It is recommended that EFL instructors in Saudi universities take a socio-pedagogical approach to teach the language and that universities provide teachers and students with adequate resources to help them understand the language.

This study evaluates the implementation of the environmental education curriculum in the Department of Environmental Education, University of Calabar, Nigeria. Using the expost facto research design, nine objectives were pursued. These include: 6 strategic objectives, the curriculum content, career prospects of graduates, and lecturer’s pedagogic knowledge and problems militating against the effective implementation of Environmental Education (E.E). A sample of 969 graduates of Environmental Education from 1997-2021, were the respondents. The researchers used an open and closed ended questionnaire with a modified four-point Likert scale response options that they designed as an instrument to collect information. Simple percentages were used for data analysis. The results of the analyses show that the curriculum content of Environmental Education as in force today is not adequate. The knowledge and awareness acquired when they studied E.E. did not help them enough to solve their community environmental problems. However, Environmental Education built their skills and prepared them well to actively participate in solving current environmental problems. Some of the lecturers who taught these respondents at undergraduate levels have the requisite pedagogic knowledge of the subject matter but, the government who is a signatory to the implementation of Environmental Education is not serious about engaging these graduates. Overall, Thirteen problems were identified as factors hampering the effective implementation of Environmental Education curriculum, and 13 feasible solutions were proffered by the respondents. It was concluded that Environmental Education in the University of Calabar has achieved some level of success, despite the fact that there are some issues that needs to be addressed to get the complete success anticipated by the crafter of the program’s objectives. It was recommended among others that a regulatory body should be created to regulate the practice of Environmental Education in Nigeria.

Pokój dziecięcy – czyli o pewnej możliwości interpretacyjnej
Authors: Lewartowska-Zychowicz Małgorzata
Published: May 2023

The aim of the text is to present the potential of Foucault’s concept of dispositive for interpreting the space of a child’s room. I look for arguments in favor of this proposal in the concepts of the place by M. Eliade, P. Ricoer, and Yi-Fu Tuan, who combine creating a place with the process of constructing human identity. In reference to them, I assume that a child can create his own identity only if he has a chance to transform the space available to him. The analysis of the history of children’s room shows, however, that his space has always been created as a result of adults’ practices aimed at educational goals. Thus, the children’s room can be treated as dispositif, serving the governmentality of child.
Teksty narracyjne uczniów w świetle morfologii Władimira Proppa

Published: May 2023

Children create narratives by imitating styles present in their culture and own experiences. Hence, nurseries and primary schools play an important role in children’s building narratives. My intention has been to present narratives constructed by children taking into consideration the form rather than the content, as it had been done by V. Propp in his morphology. This type of researching children’s texts has not been previously employed in early school pedagogy. The analyses demonstrated that most stories created by early school pupils assume the form of modified and updated fairy tales, with a different number of functions.
Edukacja dziecka ku ponadczasowym wartościom – rozważania na przykładzie współczesnej "Baśni o perle" Anny Gibasiewicz
Authors: Józefowicz Anna
Published: May 2023

Baśń o perle (ang. Fairy tale about a pearl) by Anna Gibasiewicz (2016), is a moving story of heroes, whose fates intertwine in extraordinary circumstances, a tale of transformation and searching for the most important things in life. By its form the fairy tale refers to the folk magic tales, the mood of melancholy is similar to Andersen’s fairy tales. The story is addressed to children at the early school age. On its example, I look at the contemporary implementation of the traditional genre, which is a fairy tale and the values carried by the story. I pay attention to fairy tales, which may form the basis for educational activities with children. Analyzing the literary text of Baśń o perle (ang. Fairy tale about pearl) I refer to psychoanalytic interpretations of folk tales made by Bruno Bettelhaim and archetypal critique by Alicja Baluch. Reading fairy tales to the contemporary child still can perform a „miraculous and useful” role in his social and emotional development.

The first part of the article presents the history of the development of the principle of viewpoints starting from its illustrative and static perception, and ending with its contemporary, interactive use. In the second part, referring to our own research, we describe and analyze the contemporary use of the principle of viewpoint during extracurricular mathematical classes organized for pre-school and younger school children. The essence of the contemporary use of the principle of objectivity is the intentional and skilful use of didactic means while shaping the mathematical concepts of students. Attention was paid to the fact that children were provided with conditions free and without time pressure to experiment with mathematical objects, the ability to agree their observations and discoveries with their peers, the teacher.
Bruno Schulz i informe. Intermedialna nieaktualność
Authors: Martinelli Hélène
Published: May 2023

The starting point of this paper was a research presentation at an academic conference about Schulz’s “antimodern modernism,” organized by Marek Tomaszewski, Małgorzata Smorąg-Goldberg, and Paweł Rodak in Paris on June 9th, 2017. At the crossroads of literature and art history, the author aims at showing how formlessness, as defined in 1929 by Georges Bataille, haunts Bruno Schulz’ fiction (in Polish “bezkształtność” or “bezformie”). His literary works have already been associated with various trends of the Central European modernism, but it should also be linked to the early development of the Informal Arts in this area, before it revolutionized post-war painting. Given Schulz’s taste for old printed books, and the nature of his own drawings and engravings (in the cliché-verre or glass print technique), a survey of all the traces of the idea of formlessness in his literary works leads to a conclusion that there is an anachronism between texts and images. Such a gap between universal form dissolution in fiction and its static graphic counterpart remains to be interpreted: how can Schulz’s works both look back to the nostalgic pre-war realities and anticipate post-war artistic, if not philosophical, tendencies?
Obraz w obrazie i rama. Schulz wobec tradycji
Authors: Kato Ariko
Published: May 2023

This article aims to reevaluate Schulz’s early drawings from 1919 to 1921, rarely included in scholarship on Schulz’s artwork, by focusing on the motifs of “picture within a picture,” imitation of historical paintings, and the frame of the image. Previous scholarship on Schulz’s artwork mainly discussed the specific theme of men’s worship of women in the 1920s cliché-verre series The Book of Idolatry and regarded Schulz’s seemingly realistic renderings as “anachronistic” compared to twentieth-century modernist art. Here, I will first focus on Schulz’s adaptation of the style of historical paintings into his so-called “masochistic motifs” of men supplicating themselves to women. By creating a gap between the style and the content expectations of the viewer familiar with the conventions of European paintings, Schulz’s early drawings question the custom or conventional understanding of paintings created for acceptance and success in the European Art Academy system. Second, I invoke Derrida’s interpretation of the concept of “parergon” in The Truth in Painting (1978) to reconsider the motifs of frame and “picture within a picture,” omnipresent in Schulz’s early drawings. Through these means, I explore Schulz’s perception and attitude regarding medium specifics of paintings as Clement Greenberg argued regarding modernist paintings. Thus, I discuss his early drawings as self-referential and radically modernist works.

We know that thanks to the protection of Zofia Nałkowska, he managed to publish his debut book with the Rój publishing house located in Warsaw. However, before it happened, he had been unsuccessfully looking for a publisher willing to take the risk of publishing a sophisticated book by an unknown author. To examine this problem, the author of the article investigates the condition of the Polish book market in the 1930s, examining surviving documentation and memories. He also analyzes what Schulz expected from his publisher and the terms under which his book was released. Finally, he attempts to calculate the benefits and losses that Schulz incurred by publishing the book with the Rój publishing house.

Über Freiheit und Notwendigkeit. Die Auseinandersetzung mit Bischof Bramhall
Authors: Hobbes Thomas
Published: May 2023

Während des englischen Bürgerkrieges fand 1645 im Pariser Exil eine zunächst höflich, dann gereizt und zuletzt erbittert geführte Kontoverse zwischen Thomas Hobbes und dem anglikanischen Bischof John Bramhall über Willensfreiheit statt. Dahinter standen zwei völlig unterschiedliche Weltmodelle und konträre Auffassungen über Materialismus, Ursache und Wirkung, Freiheit sowie das, was man eigentlich unter einem »Willen« zu verstehen habe. Hobbes’ fundamentale Attacken auf den »liberum arbitrium«, der seit Augustinus als undiskutierbare Voraussetzung für persönliche Verantwortung und moralische Zurechnung gesehen wurde, trafen bei seinen Gegnern auf nachdrücklichen Widerspruch. Sein neuartiges Freiheitsverständnis, wonach Freiheit darin bestehe, ungehindert handeln zu können, reichte über die jahrhundertelang geführte theologische Willensfreiheitsdebatte weit hinaus und beantwortete die Frage nach dem freien Willen schlicht negativ. Der Vorwurf, er würde damit nicht nur die Religion zerstören, sondern auch das Fundament jeder Gesellschaft untergraben, traf in ähnlicher Form später auch Spinoza. Die Diskussion zwischen Hobbes und Bramhall dokumentiert nicht nur beispielhaft die philosophischen Umbrüche, die der Aufstieg der Naturwissenschaften in der Frühen Neuzeit mit sich brachte, sondern bildet auch den Anfang der modernen Debatte über Willensfreiheit. Viele heute noch diskutierte Aspekte der komplizierten Problematik finden sich bereits hier. Die Ausgabe enthält Hobbes’ Werke »On Liberty and Necessity« sowie (auszugsweise) »The Questions Concerning Liberty, Necessity, and Chance« mit den Kommentaren von John Bramhall. Mit einer Einleitung und Anmerkungen des Herausgebers, einem Register und einem Verzeichnis der angeführten Bibelstellen.

Language teachers in synchronous and asynchronous online teaching: A student’s perspective
Authors: Méndez Rojas Dulce Brenda
Published: May 2023

COVID-19 fostered education to adapt from face-to-face to synchronous and asynchronous classes so that teachers and students had to migrate to a new way of teaching and learning. There was a period of adjustment (the first three weeks of online learning) for both, teachers and learners; the support provided by teachers differed from this period of adjustment to the support provided after. The perspective that students had about how much a teacher helped or how important was his or her companionship changed. This study was conducted at the Language Center Orizaba that is part of a public university in Mexico named Universidad Veracruzana; in a group of 53 participants in A2 level of English in 2020. Participants answered two questionnaires, one during the period of adjustment from face-to-face classes to synchronous and asynchronous lessons and a second questionnaire at the end of the semester. They started the semester having face-to-face classes so they did not have previous experience in taking online classes. The data collected with both questionnaires were analyzed and categorized; results showed that students need the support of a teacher to tell them how well they are doing and to promote interaction and learning. Moreover, students got strategies that are used in autonomous learning which made them to be more aware about their learning,

La tarea narrativa durante la práctica oral en salón de inglés como lengua extranjera
Authors: Garcia-Ponce Edgar Emmanuell
Published: May 2023

Por más de tres décadas, las tareas han sido utilizadas para enseñar y aprender la lengua debido a que promueven procesos cognitivos necesarios para el desarrollo lingüístico. Sin embargo, la implementación de las tareas ha estado rodeada de controversia motivada por limitaciones cognitivas y prácticas que atañen su efectividad. En relación a esto, se llevó a cabo un estudio con el objetivo de explorar los efectos de una tarea narrativa en el desempeño oral de estudiantes universitarios a través de tres dimensiones de la lengua: complejidad, precisión y fluidez. También, con la ayuda de entrevistas, se examinaron sus percepciones sobre esta tarea y su desempeño oral. Los resultados muestran que las características de esta tarea motivan a los estudiantes a construir estructuras orales más complejas, pero a expensas de la fluidez y precisión. Además, al explorar sus percepciones, los resultados sugieren que la falta de familiaridad con esta tarea los lleva a percibirla como una tarea difícil, con una exigencia elevada de habilidades orales y a su vez complejidad para lograr el objetivo de la tarea. Este artículo proporciona algunas implicaciones pedagógicas que los maestros de lengua deben de tomar en consideración al usar tareas para practicar y evaluar la lengua.
