Authors: Wnuk Marian
Published: February 2024

The surface impedance of the multilayer dielectric structure was determined. Based on the boundary conditions, a method for determining the surface impedance of a layered structure with a perfectly conductive screen and or a magnetic screen is presented. The resonance conditions and the conditions for the excitation of surface waves are derived. The integral expression defining the generalized impedance was analyzed with a view to adapting it to numerical implementation. This allowed the development of a computer program based on which calculations were made of the effect of excitation of waves on multilayer dielectric substrates.

Authors: Tibi Sedra , Tieu Vivian , Ling Jun
Published: February 2024

Background and Objectives: Cancer as the second leading cause of death in the United States poses a huge healthcare burden. Barriers to access to advanced therapies influence the outcome of cancer treatment. In this study, we examined whether insurance types affect the quality of cancer clinical care regarding access to an important monoclonal antibody, ramucirumab. Materials and Methods: Data for 13,340 cancer patients with Purchased or Medicaid insurance from the All of Us Database were collected for this study. The Chi-square test of proportions was employed to determine the significance of patient cohort characteristics and ramucirumab usage between Purchased and Medicaid insurance groups. The independent t-test was utilized to assess the influences of other determinants on insurance types. Results: Cancer patients who are African American, with lower socioeconomic status, or with lower educational attainment are more likely to be insured by Medicaid. Analysis of survey questions demonstrated the relationship between income and education level with insurance type as Medicaid cancer patients were less likely to receive primary care and specialist physician access and more likely to request lower cost medications. In addition, those with Medicaid insurance were identified to have poorer access to expensive therapeutics like ramucirumab compared to those with Purchased insurance.  Conclusions: The inequities of the US healthcare system are observed for cancer patient care; access to physicians and therapeutics are highly varied and dependent on insurance types. Socioeconomic status determines insurance type, which unfortunately generates a significant impact on cancer treatment and disease outcome.

Published: February 2024

The interaction between native and invasive plant species plays a crucial role in understanding invasion mechanisms and developing control strategies. This study investigated the differences in photosynthetic and fluorescence parameters, gene expression profiles, and rhizosphere soil microbial composition between the native species Ficus tikoua Bur. and the invasive species Alternanthera philoxeroides. For the first time, it was demonstrated that that F. tikoua Bur. may enhance photoinhibition ability and the expression of genes involved in carbon metabolism, protein processing in the endoplasmic reticulum, and plant-pathogen interactions to maintain growth. Additionally, it recruits beneficial microbes, e.g. Actinomarina (Bacteria), Nitrosotenuis (Archaea) and Laccaria (fungi), to suppress pathogens, thereby preserving soil DMSP and carbon cycling pathways to resist invasion by A. philoxeroides. These findings provide novel insights into the mechanisms underlying plant invasion and suggest potential strategies for invasive plant management. Further research is needed to investigate this relationship and determine the mechanisms underlying the potential resistance of F. tikoua Bur. to plant invasion.
The Electric Charge Influence on Space-Time Curvature
Authors: Lavi Eran Magshim
Published: February 2024

This article presents a novel approach to understanding the influence of electric Energy on space-time curvature. EFE actual calculations refer solely to gravitational charges. In this article, I expand them to include the electric charge with calculations carried specifically for electric charges, with exciting results. The article leverages the universal consistency of physical laws, applying the known effects of gravitational charges on space-time curvature to electric charges. The research focuses on calculating the specific impact of electric charges on space-time curvature, rooted in the principle that space-time curvature is omnipresent. The findings reveal that space-time curvature's alteration due to an electric charge is influenced by various factors, including the charge's location, magnitude, mass, density, associated electric field, and its motion through space-time. Notably, the conversion factor for electric charges differs from the conversion factor for gravitational charges. These insights significantly enhance our understanding of electromagnetism and general relativity, paving the way for a more profound comprehension of electric charges.

Published: February 2024

Echis carinatus and E. ocellatus belong to the most deadly snakes. We investigated pooled venom using data-independent and target high-resolution mass spectrometry. Since the reference protein databases for both species were not comprehensive, we additionally searched those of higher orders. Interestingly, considerable amounts of three-finger toxins including long neurotoxin 1, weak toxins and short neurotoxins were detected in E. carinatus, which are hallmarks of elapid, not viperid, snakes. The presence of these toxins was confirmed by manual fragment ion analysis of selected peptides. The larger proteins snake venom vascular endothelial growth factor toxin barietin and basic phospholipase A2 ammodytoxin C were also found in both venoms with sequences not known in this genus so far. This study provides new confirmed peptide sequence information for 11 smaller proteins of E. carinatus and E. ocellatus.

Authors: Roslova Maria , Büchner Bernd , Maljuk Andrey
Published: February 2024

In this review, we summarize recent progress in crystal growth and understanding the influence of crystal structure on the superconductivity in pure and Pb-doped Bi2Sr2CuOy (Bi-2201) materials belonging to the overdoped region of high temperature cuprate superconductors. The crystal growth of Bi-2201 superconductors faces challenges due to intricate materials chemistry and lack of knowledge of corresponding phase diagrams. Historically, a crucible-free floating zone method has emerged as the most promising growth approach for these materials, resulting in high-quality single crystals. This review outlines the described in the literature and the authors' synthesis endeavors, encompassing Pb-doped Bi-2201 crystals, detailed structural characterization of as-grown and post-growth annealed samples, and highlights optimal growth conditions that yield large-size, single-phase, and compositionally homogeneous Bi-2201 single crystals.

Published: February 2024

This retrospective study aimed to compare risk factors for vascular calcification (VC) between pre-hemodialysis (HD) and prevalent HD adult patients while investigating associations with calcification biomarkers. Baseline data from 30 pre-HD and 85 HD patients were analyzed, in-cluding iPTH, vitamin D, FGF-23, fetuin-A, sclerostin and VC scores (Adragao method). Preva-lence of VC was similar in both groups, but HD patients had more frequent VC scores ≥6. Pre-HD patients were older, with higher prevalence of hypertension and less frequent use of calcium phosphate binders. Both groups showed similar patterns of hyperphosphatemia, low vitamin D, and iPTH. Fetuin-A levels were higher in pre-HD, while FGF-23 was elevated in HD patients. Higher VC risk in pre-HD patients was associated with male gender, older age, lower fetuin-A and higher sclerostin, lower ferritin and no vitamin D treatment, while in HD patients with higher sclerostin, FGF23 and urea, and lower iPTH. Conclusion. Progression of CKD from the pre-HD to the HD stage is accompanied by a decreased effect of the inhibitor and an increase in the promoter VC. However, mineral imbalance, hormonal regulation, treatment options, and patient-specific fac-tors should be considered. Further studies are needed to elucidate the underlying pathways.

Published: February 2024

Inositol is a natural carbocyclic sugar that plays an essential role in regulating the vital cellular functions of plants and animals. Current research has explored methyl derivatives of inositol, reporting on their various biological activities, including antitumor, anti-inflammatory, and anti-osteoporosis activities. Our previous study demonstrated that L-quebrachitol, a methyl derivative of inositol, enhances osteoblastogenesis and bone formation; however, its effect on osteoclastogenesis remains unclear. Consequently, we aimed to investigate the effect of L-quebrachitol on the receptor activator of nuclear factor-κB ligand-induced osteoclastogenesis in pre-osteoclastic RAW 264.7 cells. The results revealed that L-quebrachitol suppressed RANK-mediated signalling, including nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and Fos proto-oncogene (cFOS) pathways, at both gene and protein levels. Moreover, the critical transcription factor for osteoclastogenesis, nuclear factor of activated T cells c1 (NFATc1), was downregulated. Inhibition of osteoclast-associated marker genes encoding proteolytic enzymes, such as tartrate-resistant acid phosphatase (TRAP), matrix metallopeptidase 9 (MMP-9), and cathepsin K, led to reduced formation of TRAP-positive multinucleated cells and resorption pits. These findings demonstrate the dose-dependent inhibitory effect of L-quebrachitol on osteoclastogenesis through the modulation of receptor activator of nuclear factor κB (RANK)-mediated signalling pathways. However, further exploration of L-quebrachitol's potential as a therapeutic approach for osteoporosis is warranted.
Hoof Capability of Barefoot-Kept Horses and Ponies Walking over Artificial Environments: An Anatomical and Radiological Study
Authors: Albanozzo Sarah , Borg Louis , Camilleri Liberato , Bowker Robert M
Published: February 2024

Hoof capability of domesticated, barefoot-kept horses and ponies traversing artificial environments remains undocumented. In this study, four equines were walked in-hand for 16 days, covering a distance of 50 km, over three solid surfaces. Subsequently, we conducted an assessment of hoof morphology. Hooves (n = 16) were radiographed before and after the trial, spaced 3 weeks apart, for sole depth measurement. External measurements of feet were recorded 24 hours before day 1 and repeated on day 9. Radiographs revealed increased sole depth in 11 hooves, notably at the palmar process, and some misalignment in certain phalanges. On day 9, after a 36-km distance, all hooves exhibited calloused soles and frogs, and required trimming. The front hooves of the horses had a pronounced, natural concavity. Hard surfaces were found to stimulate sole growth, with a portion of sole thickness preferentially accumulating within the dermal zone. Collectively, the maintenance of short trimming cycles to prevent misalignment, minimize hoof-wall loading and maintain a load-sharing system, may be necessary for barefoot-kept horses considering their rapid growth rate.

Published: February 2024

When examining the crucial role of civic competence in fostering sustainable societies, economies, and ecosystems, its significance for cultivating responsible and engaged citizens in our ever more interconnected global landscape must be recognized. Notably, education influences the development of civic competence throughout the learning experience at all levels of education. This research aims to explore the evolution of students’ self-assessment in terms of civic competence and its three sub-competences. The objective is to comprehend the present status of students’ self-assessments and explore their potential impact on the formation of a sustainable society. Data were collected for this study using an assessment tool elaborated in the ESF project “Development and Implementation of the Education Quality Monitoring System” for students’ generic competences. The tool, presented in a digital form using the QuestionPro platform, measures six generic competences, including civic competence. A total of 1,166 bachelor students and 354 Master’s students participated in the study, representing 22 Latvian higher education institutions. The study’s findings indicate that civic competence in the sample is considerably lower than the other generic competences measured, with a greater dispersion of results. The results also highlight specific areas within universities that require improvement during the learning process to cultivate individuals who are sustainable and socially responsible members of society.

Authors: Yilan Shao , Yifan Bai , Zhehui Cai , Nan Pu , Huawei Zhang
Published: February 2024

In order to improve the yield of the therapeutic agent N-methylsansalvamide (SA), optimization of stationary liquid fermentation conditions was carried out on an endophytic strain, Fusarium sp. R1, at flask level. Using a One-Factor-At-a-Time approach, the fermentation conditions for SA production were determined as follows: fermentation time of 13 d, 24 oC, initial pH of 6.5, seed age of 24 h, inoculum size of 5.0% (v/v), loading volume of 50% (v/v), 20.0 g/L salinity, and sucrose, tryptone, and yeast extract were found to be the best sources of carbon and nitrogen. Using response surface methodology, the optimal medium compositions consist of 22.5 g/L sucrose, 16.5 g/L tryptone, and 0.024 g/L yeast extract. Verification tests suggested that the SA yield under these optimal conditions reached up to 536.77 ± 2.67 mg/L, which was increased by almost ten times the initial yield (54.05 ± 3.45 mg/L). The findings indicate that a high SA production yield can be achieved by static culture of strain R1 under the proper fermentation conditions using a low-cost medium. This study paves the way towards industrial-scale SA production by strain R1 for new drug development.

Published: February 2024

This study determines the equivalent stress intensity factor (SIF) model that best fits the experimental behavior of low-carbon steel under mixed mode (I and II). The study assessed Tanaka, Richard, and Pook's equivalent SIF models. The theoretical values used for comparison correspond to experimental results in a modified C(T) geometry by machining a hole ahead of the crack tip subjected to fatigue loads with a load ratio of R = 0.1. The comparison involved the SIF for six experimental points and the values computed through the numerical simulation. The Paris, Klesnil, and modified Forman-Newman crack growth models were used with each equivalent SIF to analyze the prediction in the estimated number of cycles. The Klesnil model showed the closest prediction since the error between the calculated and experimentally recorded number of cycles is the lowest. However, the material behavior reflects a reduced crack propagation rate attributed to plasticity in the crack tip. Results suggest that Asaro equivalent SIF conservatively estimates the element lifespan with increasing errors from 2.3% at the start of growth to 27 % at the end of the calculation.
Robotic Odor Source Localization via Vision and Olfaction Fusion Navigation Algorithm
Authors: Hassan Sunzid , Wang Lingxiao , Mahmud Khan Raqib
Published: February 2024

Robotic odor source localization (OSL) is a technology that enables mobile robots or autonomous vehicles to find an odor source in unknown environments. An effective navigation algorithm that guides the robot to approach the odor source is the key to successfully locating the odor source. While traditional OSL approaches primarily utilize an Olfaction-only strategy, guiding robots to find the odor source by tracing emitted odor plumes, our work introduces a fusion navigation algorithm that combines both vision and olfaction-based techniques. This hybrid approach addresses challenges such as turbulent airflow, which disrupts olfaction sensing, and physical obstacles inside the search area, which may impede vision detection. In this work, we propose a hierarchical control mechanism that dynamically shifts the robot’s search behavior among four strategies: crosswind maneuver, Obstacle-avoid Navigation, Vision-based Navigation, and Olfaction-based Navigation. Our methodology includes a custom-trained deep-learning model for visual target detection and a moth-inspired algorithm for Olfaction-based navigation. To assess the effectiveness of our approach, we implemented the proposed algorithm on a mobile robot in a search environment with obstacles. Experimental results demonstrate that our Vision and Olfaction Fusion algorithm significantly outperforms Vision-only and Olfaction-only methods, reducing average search time by 54% and 30%, respectively.
Performance Evaluation of Calcined Phosphogypsum Reinforced with Basalt Fiber and Calcium Carbonate Whiskers: A Study on Individual and Mixed Tests
Authors: Yong Jiang , Jichuan Huo , Yonglin Lei , Lujun Jia
Published: February 2024

To address the insufficient mechanical properties of calcined phosphogypsum, this research aims to investigate the utilization of basalt fiber and calcium carbonate whiskers as reinforcing agents. The study examines their impact on the flexural and compressive strength, toughness, water resistance, and tensile strength of calcined phosphogypsum. In the individual tests, basalt fibers with different lengths (3 mm, 6 mm, 9 mm, and 18 mm) were added at dosages of 0%, 0.5%, 1.0%, and 1.5% respectively. The findings demonstrate that basalt fiber effectively enhances the flexural and compressive strength, toughness, and tensile strength of calcined phosphogypsum, albeit potentially compromising water resistance. Among the various fiber lengths, the 6 mm fibers exhibit the most advantageous influence on the performance of calcined phosphogypsum. A subsequent test was conducted to investigate the impact of cross-scale fibers on the properties of calcined phosphogypsum by mixing 6 mm basalt fibers and calcium carbonate whiskers. The results illustrate that calcium carbonate whisker refines the pores, thereby improving the flexural strength and toughness of calcined phosphogypsum. Furthermore, it compensates for the water resistance limitations associated with the sole utilization of basalt fiber while further augmenting the tensile strength and strain capacity. However, it should be noted that increasing the dosage of both calcium carbonate whiskers and basalt fibers concurrently leads to increased porosity of phosphogypsum and reduced compressive strength.
Conceptualizing Electromagnetic Field Detection for Emotional Contagion in Hri: Towards a Multimodal Approach
Authors: Valluri Durga Deepak
Published: February 2024

This conceptual paper explores the potential of integrating Electromagnetic Fields (EMF) with traditional physiological signals to enhance emotional contagion in Human-Robot Interaction (HRI). A focused literature review identifies gaps in current HRI models that rely solely on visual, auditory, and known physiological cues for emotional exchange. A novel framework is proposed, incorporating EMF as a complementary modality, aiming to deepen emotional synchronization between humans and robots. The paper lays groundwork for future research to consider EMF detection as a complementary modality alongside traditional cues. It also addresses technological requirements and discusses potential limitations. By extending the modalities used in emotional contagion, this work seeks to advance the development of more intuitive and empathetic robotic systems.

Solar photovoltaic (PV) generation suffers from multiple serious issues, for example shading effects directly affect the performance of installed PV arrays. By studying these issues, it can play a key role in improving the limitations and performance of PV panels. The study of PV arrays under partial shading conditions is mentioned in many papers as a part of other studies and as an independent phenomenon. Therefore, it is essential to improve these studies and update them with new research and study this problem in detail to know how to limit the effects of partial shading irradiance conditions on PV arrays performances, including economical aspects. This paper proposes to study the effects of different partial shading irradiance conditions for a PV array in various configurations. The analysis is proved in detail through the simulation of the proposed PV array in the Matlab/Simulink environment. The obtained results show the performances of interconnected PV arrays under different partial shading irradiance and temperature conditions, including the solar array I-V and P-V characteristics. In addition, different PV array configurations with and without bypass and blocking protection diodes improve and minimize the effect of partial shading conditions and avoid the reductions in output power.

Published: February 2024

Abstract: A. baumannii exhibits resilience in harsh environments and progressively develops resistance to diverse antibacterial agents over time. This adaptability poses a significant challenge in treating an infection caused by this bacterium within healthcare settings. The presence of peptidoglycan, a crucial precursor for cell wall synthesis, contributes to this challenge. Peptidoglycan serves not only as a structural support in bacterial cells but also provides protection against adverse environmental conditions. The synthesis of the peptidoglycan layer involves a group of substrates such as N-acetylglucosamine (GlcNAc) and N-acetylmuramic acid (MurNAc), within a three-partitioned process occurring in the membrane, periplasmic space, and cytoplasm of each bacterium. Initiated in the cytoplasm and extending to the inner cell membrane, this synthesis starts with the production of nucleotide precursors. The first step involves the synthesis of UDP-GlcNAc, orchestrated by Glm (GlmS, GlmM, and GlmU) enzymes using fructose-6-phosphate. Subsequently, enzymes from the Mur family, namely MurB, MurA, MurD, MurC, MurI, MurF, and MurE, synthesize UDP-N-acetylmuramyl-pentapeptide (UDP-Mpp) from UDP-GlcNAc. Concurrently, on the cytosolic side, the production of membrane-surrounded undecaprenyl phosphate occurs, involving membrane-side proteins MraY and MurG in the biosynthesis of peptidoglycan. This review emphasizes updated information on Mur family proteins, encompassing physicochemical properties, nature of binding site, number and type of binding site residues, functional domain details, three-dimensional structural aspects, and their functions within bacterial cells. Special attention is directed towards their enzymatic role in peptidoglycan biosynthesis due to the limited availability of precursors in the market. Additionally, the review provides a comprehensive summary of existing inhibitors and ongoing efforts in identifying new targeted inhibitors, recognizing these enzymes as potential candidates for antibacterial drug design and discovery.

Published: February 2024

Remotely controlled robots are required to operate in human-inaccessible environments, such as the decommissioning of nuclear power plants. In our previous studies, we proposed a modularized rail structure for such environments. In long-term decommissioning work at a nuclear power plant, robots are controlled by inexperienced operators who have limited knowledge of the design details of the robots. In this study, we developed a remote construction system for supporting inexperienced operators by transmitting the status information of the constructor robot to the operator during the remote construction of a modularized rail structure. The proposed remote construction system was designed based on a human information-processing model. Experiments were conducted using the developed remote construction system. The proposed method achieved a success count of inexperienced operators equivalent to that of skilled operators. Furthermore, a questionnaire administered to participants showed that their cognitive, psychological, and physical loads during construction were sufficiently low during the experiment.
Integration of Multiple Sensors into an ROV for Remote Measurement in the Fukushima Daiichi Nuclear Power Station
Authors: Kamada So ,   Editorial Office, Nishimura Kazuya
Published: February 2024

To measure and analyze the distribution and criticality of submerged fuel debris “in situ” in the decommissioning process of the Fukushima Daiichi Nuclear Power Station (1F), we developed a system for remote measurement using multiple sensors consisting of the neutron sensor, the sonar, and the sub-bottom profiler (SBP) mounted on a small remotely operated underwater vehicle (ROV). First, the locations presumed to contain fuel debris were explored based on the information of the water bottom shape obtained using the sonar and the bottom surface substructure obtained using the SBP. Second, the system identified the location of fuel debris by detecting neutrons emitted by spontaneous fissions of fuel debris using the neutron sensor with diamond elements. Simulated fuel debris was placed at the bottom of a test water tank that simulated the pedestal. In the primary containment vessel (PCV) of 1F, and a verification test of remote measurement was conducted using the ROV mounted on the multiple sensors. The desired results were obtained.

Published: February 2024

The transfer of stagnant water from the basement floor of the waste treatment building at the Fukushima Daiichi Nuclear Power Station is planned because of the possibility of water flowing out of the building if another tsunami occurs. However, the basement floor is installed with high-dose zeolite sandbags as adsorbents for radioactive materials, which renders their removal challenging. In this study, we conduct a field survey and field reproduction as well as develop a robot that can perform zeolite removal based on the results obtained. In addition, we perform verification tests in a full-scale mock-up test environment and extract issues for application to actual equipment.

Published: February 2024

Ocean waves play a significant role in coastal dynamics and the management of coastal development activities. However, there are limited instruments to measure the wave height, particularly in developing countries. This study introduces a novel instrument design for simple and cost-effective wave height measurement. The proposed instrument combines a Hall-effect sensor and an accelerometer to capture the rise and fall of a buoy in response to wave movements. The Hall-effect sensor as a rotary encoder detects the rotation of the buoy while the accelerometer measures the tilt of the instrument caused by ocean waves. The instrument is constructed using PVC pipes and incorporates long-range (LoRa) communication technology for real-time monitoring. Experimental tests were conducted at a study site in Banyuwangi Regency, Indonesia, where the performance of the instrument was compared with an ultrasonic sensor-based instrument. The results validate the effectiveness of the proposed instrument design for wave height measurement. The collected data were transmitted via the LoRa communication system, enabling convenient monitoring and analysis of sea-level changes. The valuable contribution of the instrument to the field stems from its precision in measuring the wave height, adaptability to diverse conditions, and potential applicability in shallow waters.

Queer temporalities in TV series Veneno: breaking down the spiral of silence through trans visibility
Authors: Ventura Rafael , Blanco-Fernández Vítor , Sánchez-Soriano Juan-José
Published: February 2024

This study explores the implications of media visibility in the evolution of public opinion about trans people in the Spanish context. We focus on the socio-cultural impact of the TV series ‘Veneno’ (2020, Atresmedia) in relation to the breaking down of the spiral of silence (Noelle-Neumann, 1993) on trans issues. Based on Esteban Muñoz's (2020) theoretical approach to queer temporalities, we conducted a 'close reading' analysis (Brummett 2018) of the diachronic narrative of the television series Veneno (2020). Through a linear observation of the past, present and future of media representation and its relationship with the real-life situation of trans people, an evolution is detected from ostracism and fetishization in the past, to a future shift towards greater normalization and livable life forms. But the results also reveal a spiral of meanings that interconnect with different temporalities and contexts, reflecting the non-linear nature of queer temporalities. Additionally, the paper discusses how this series, due to its media impact, has contributed to socio-political public debate on the need to address the rights of trans people in modern-day Spanish society. Finally, its impact not only relies on improving trans visibility by portraying trans narratives, but we also discuss how the series is playing an important role in queering the media industry itself, ensuring trans people to work both in front and behind the cameras.

Resignificación del lenguaje periodístico cliché en tres crónicas de Jaime Bedoya
Authors:   , Vizcardo Delgado Aarón Augusto
Published: February 2024

Las crónicas de Jaime Bedoya nos dan cuenta de un tratamiento especial con el lenguaje. En ellas se recogen elementos presentes en los medios de comunicación tradicionales: hablamos de los clichés. En ese sentido, nuestro análisis propone la categoría de lenguaje periodístico cliché como un insumo importante de la escritura del autor y se enfoca en cómo se resignifica este tipo de discurso. Para ello, partimos de la retórica moderna y la pragmática para identificar cómo se efectúa este proceso de resignificación. Asimismo, detectamos la presencia de un registro irónico, que apela al conjunto de conocimientos que comparte el productor del texto con el lector. Bedoya explora y critica creativamente estos elementos, nos brinda una visión y tratamiento del cliché distinta a la que maneja en su uso cotidiano.
The Beginnings of Philosophical Theology: V. Yeager's book "The Theology of the Early Greek Philosophers"

Выход научной работы В. Йегера «Теология ранних греческих философов: Гиффордские лекции, 1936» (2021) на русском языке является актуальным. Эта актуальность диктуется сциентизмом и релятивизмом, воцарившимся как в обществе, так и в науке. В статье подчеркивается важность исследовательского подхода В. Йегера, основанного на классической филологии и учитывающего религиозный контекст Древней Греции. В то же время работа В. Йегера выступает образцом историко-философского исследования, где идеи ранних мыслителей Греции представлены в рамках возобновления интереса к теологии. Философское наследие ранних греческих мыслителей из-за своей фрагментарности представляет собой сложный для интерпретации предмет. Несмотря на это, выдающиеся исследователи в области истории философии рассматривают первых греческих философов либо как первых естествоиспытателей, либо как верных продолжателей орфизма. По прошествии времени эти подходы обрели статус традиций, прочно закрепившись в академической, учебной и популярной литературах, вокруг которых до сих пор происходят научные дискуссии. В связи с этим мыслители ранней Греции представлены читателю, ранее незнакомому с этой традицией мысли, как первые ученые или мистики, что не всегда соответствует мировоззрению первых интеллектуалов Эллады. Лекции В. Йегера предлагают иной взгляд на первых мыслителей Эллады, представляя их как первых рациональных теологов, живших до становления авраамических религий. В то же время немецкий исследователь попытался осветить взаимосвязь между ранними теогониями, античной поэтикой и философским размышлением.
The observation event and the observed event in the "Legendary Topography" by M. Halbwaks

Автор, с опорой на работу Мориса Хальбвакса «Легендарная топография Евангелий в Святой Земле», рассматривает проблемы соотношения события наблюдения и наблюдаемого события, а также проясняет пространственный аспект в «теории социальных событий». В статье используется определение события как смыслового комплекса, означающего соотносительное акту наблюдения единство, связанное со свершением в пространстве и времени (А. Филиппов); эта трактовка позволяет использовать работу Хальбвакса в качестве ресурса для разрешения некоторых противоречий теории событий. Далее автор, касаясь происхождения теории событий и места наблюдателя и пространства в идеях ее представителей, обращает внимание на некоторые сложности. Во-первых, по мнению автора, требует дальнейшей разработки верификация наблюдений, фигура наблюдателя и связь описания и события; во-вторых, несмотря на важность пространственного аспекта, занимающего ключевую роль в дефиниции события, исследователи описывают место нахождения наблюдателя, а не свершения события; еще более запутанной становится ситуация, когда речь идет о масштабных событиях. Используя выводы Хальбвакса, который иллюстрирует в «Легендарной топографии» положения, высказанные ранее в «Социальных рамках памяти», автор настаивает на том, что группа является детерминирующим актором коллективной памяти; обладая общей системой различения, группа конституирует конвенциональный образ события. Независимо от того, что произошло, группа имеет дело с наблюдением следов, при отсутствии непосредственного контакта, наблюдатели, конституируя событие, в том числе реконструируют пространство, в котором это событие могло бы произойти, то есть место оказывается следствием последовавших событий наблюдений.
Modern Information Society as a methodological object: the dialectic of technology and new sociality

Современное информационное общество, являющееся социально-технологическим интерфейсом между глобальным информационным пространством и человеком, построенное на технологиях сетевизированных цифровых коммуникаций, является одной из немногих опор глобализации, которая вряд ли будет демонтирована даже при реализации критических сценариев глобальных трансформаций. Тем не менее информационное общество будет объектом нарастающего воздействия меняющейся внешней – политической, экономической и социокультурной – среды, что существенно изменит его характер. Существенно возрастает значимость корректного осознания современного информационного общества как объекта заведомо нецелостного, способного на определенных этапах своего развития к не-синергичности изменений без утраты своих социо-технологических функций. В особенности эта черта современного информационного общества проявляется в период нарастания мозаизации и атомизации социального пространства, специфической частью которого информационное общество является. Разрушение монопольного положения универсалистской модели социального развития, характерной для периода поздней глобализации, создает условия для реализации этого свойства информационного общества.
Man as an open diversity (reflection on the book "Man as an open integrity")

Эта статья – размышление над коллективной монографией [Киященко, Сидорова 2022], в которой представлен уникальный ландшафт-тезаурус с терминологическими и понятийными сетями и их связями, разнообразие авторов и трансдисциплинарные подходы к проблеме человека. Показывается, что авторы книги предлагают не столько решение и «закрытие» проблем, сколько новую проблематизацию человека как открытой антропоцелостности и неисчерпамости. Человек оказывается креативным, прокреативным, лингвокреативным, даже цифровым субъектом, вовлеченным в антропологический кризис, полный угроз его прокреативному самовоспроизведению (и в биологическом, и социальном смысле), идентичности в техносфере, виртуальном и реальном мире. Авторы размышления стремятся показать небесспорность представления об углублении антропологического кризиса в свете того, что каждому живущему поколению именно собственные невзгоды кажутся уникальными, а дефицит способности к состраданию был характерен для всех исторических эпох. В рамках мета-анализа также показывается, что цифровизация человека в виде множества электронных профилей и «следов» является не только угрозой социальности, но и имеет позитивные следствия в виде возможностей расширения человеческого опыта в рамках различных «цифровых» жизней, а «гибридная», многоликая идентичность человека имеет не только негативные стороны, но и находит позитивную оценку в межкультурной теории, где мигрант обладает преимуществом своего рода «стереоскопичности» восприятия из-за владения сразу несколькими культурно-языковыми и когнитивными потенциалами.
