Authors: Manchur Iryna
Published: July 2023

This article is devoted to the study of the nature of the reflection of such geopolitical events as the russian-Ukrainian war of 2022 in the note "events after the reporting period" of the annual financial statements of transnational companies for the year 2021.
The article examines annual reports, for which the reporting period is from January 1, 2021 to December 31, 2021, and the russian-Ukrainian war began on February 24, 2022, the specified geopolitical event is the second type of event - an event that indicates the conditions that arose after the reporting period. Thus, according to the recommendations of the consulting company BDO and the auditing company KPMG, this event does not require the adjustment of the indicators of the annual report.
Experts of the auditing company KPMG substantiated this statement by the fact that significant changes in the economic conditions of business and the political environment, as a direct consequence of the war, occurred after the end date of the reporting period. Substantial changes mean the military invasion of russia on the territory of Ukraine and, as a result, the introduction of economic sanctions against the government and business of russia and Belarus by the international community.

Authors: Mandych Oleksandra , Babko Natalia , Pasemko Galyna , Girzheva Olga , Taran Oksana
Published: July 2023

The article is devoted to the definition and analysis of the circular economy as the basis for sustainable development of the country. The author identifies the main differences between the circular economy model and the traditional model, characterised by close interconnection and interdependence of all industries, production links and trade and consumer relations, which ensures maximum benefit from available resources. The principles of the circular economy are considered and the main advantages and disadvantages of the circular economy model are revealed. The economic advantages of the closed-loop economy include the formation of a sustainable demand for secondary material resources (and, as a result, a reduction in demand for primary resources in the long term); creation of economic incentives for further investment in the use of secondary raw materials due to the exhaustion of primary material resources; reduction of costs for the maintenance of waste storage areas; and reduction of environmental taxes. The environmental benefits of the circular economy are represented by reduced carbon dioxide emissions; reduced landfill and waste storage areas; reduced consumption of scarce and limited resources, etc. Social benefits are due to an increase in the level of social responsibility for the careful use of material resources; ensuring an environmentally friendly attitude to used goods; an increase in the number of jobs for secondary material resource technologists, etc. Examples of the implementation of the basic principles of the circular economy are given, and thanks to the involvement of new business models, technological enterprises have become able to comply with the principles of the closed-loop economy. The national peculiarities of Ukraine's transition to the circular economy model are analysed.

Authors: Dziubanovska Nataliia , Maslii Vadym
Published: July 2023

The article discusses the main indicators of the digitalization of the economies of the European Union countries and analyzes their dynamic series. The clustering method is used to divide the 27 EU countries into groups with similar levels of development of the digital economy components. The multiple regression analysis method is applied to each cluster to identify the main determinants of the impact on foreign investment processes.
The purpose of the article is to investigate the influence of the digitization of the EU economy on foreign investment processes. The main task is to identify the most significant factors of the digital environment of European countries and assess their impact on investment flows, both internal and external.
Methodology. The theoretical and methodological basis of the study is scientific works of scholars on the assessment of the impact of the main characteristics of the digital economy on foreign investment processes in the EU countries. In the process of research, general scientific and special methods are used, including analysis and synthesis (to analyze the dynamics of digital economy indicators of 27 EU countries); cluster analysis - for grouping EU countries by the intensity of development of digital processes; graphic - for visualizing the obtained results; multiple regression analysis - to identify the main determinants of the impact on investment activity in the EU countries; abstract-logical (for interpretation of the obtained results and formation of conclusions and recommendations).
Results. According to the analysis of the dynamic series of indicators of the digital economy of EU countries, they were divided into 5 clusters based on the intensity of digital infrastructure development. For each cluster, a multi-factor regression analysis was conducted to investigate the dependence of the investment climate of EU countries on digital transformations. The analysis results confirm that the formation of digital infrastructures can provide favorable conditions for foreign investors and reduce barriers to their entry into the market. However, for the successful implementation of digital technologies in the processes of attracting foreign investments, it is necessary to ensure a high quality regulatory environment and an appropriate level of preparation of employees for the use of new technologies.

Published: July 2023

A gas–liquid discharge plasma (GLDP) reactor is used to degrade organic pollutants such as phenol. GLDP contains a 7-pin plate system used to enhance phenol degradation in the presence of various pH, and gas bubbles produced from air, O2, O3, CO2, and Ar gases. Experimental outcomes show the impact of solution pH, as phenol degradation efficiencies of 85%, 90%, 96%, and 98% were obtained for pH of 12, 9, 3, and 1, respectively, after 60 min of treatment. This shows that the optimum pH for phenol degradation lies between 1 and 3. Moreover, we explored the influence of gas bubbles generated using various gases, such as air, O2, O3, CO2, and Ar, on phenol degradation. In the presence of O3 gas bubbles, the rate and degree of phenol degradation were significantly increased compared to gas bubbles produced from other gases (O2, CO2, Ar, and air). The degradation competence of phenol by added oxygen remained higher than argon. The performance of the GLDP system at various pH values and gas bubbles was evaluated using kinetic models. Pseudo-zero, first and second reaction kinetics models were used to examine the degradation of phenol. The rate of degradation at different pH and in the presence of gas bubbles follows pseudo-zero-order kinetics. Our GLDP reactor consumed energy of 127.5 J l−1 for phenol degradation under the influence of air bubbles and pH 5. The outcome of this research can help in the design of new reactors for industrial wastewater treatment.

Published: July 2023

We demonstrate a monolithic InGaN light-emitting diode (LED) that emits red, green, and blue (RGB) light. The proposed LED has a simple structure with stacking RGB light-emitting layers on n-GaN, wherein unnecessary layers were removed based on the desired emission color and stacking p-GaN layer. The electroluminescence characteristics of the LED indicated that the peak wavelengths at 20 mA are R: 632.9 nm, G: 519.0 nm, and B: 449.5 nm, and the external quantum efficiencies are R: 0.28%, G: 8.3%, and B: 0.84%. This structure can be manufactured using only semiconductor processes, thus rendering smaller and higher-resolution microdisplays possible.
“Don’t complain and do it properly”: ‘Pedagogicalized parents’ and the morality of doing homework
Authors: Colla Vittoria
Published: July 2023

In the last decades, pedagogical studies and policies in western countries have proposed parental involvement in education as the formula for maximizing students’ success and increasing social equality. In the building of the family-school partnership, a crucial role is commonly attributed to parent-assisted homework. Therefore, parental involvement in homework has increased and the model of the “involved” and “pedagogically competent” parent has become common. Analyzing video-recorded parent-child interactions during homework, this paper illustrates how parents make relevant and educate their children to moral horizons concerning homework, education, and schooling. The moral beliefs evoked by the parents in the study are significantly aligned with the school culture. Parent-assisted homework therefore becomes a particularly relevant arena for children’s socialization into the cultural and moral horizons of the school system. Yet a socio-pedagogical issue emerges: if the school relies heavily on the family for homework activities, what happens to those children who cannot rely on school-aligned, pedagogically competent parents?
Il Reddito di Cittadinanza come opportunità di formazione, capacity building e integrazione fra servizi. L’esperienza del corso nazionale per case manager
Authors: Petrella Andrea , Zenarolla Anna , Capparotto Luisa , Milani Paola
Published: July 2023

There is a wide agreement in the literature that educational poverty is considered as a multidimensional and complex phenomenon, as well as a predictor of social inequalities in adulthood. The Italian key-policy against poverty (in Italian, Reddito di Cittadinanza, since 2019) aims at facing this phenomenon through the activation, for some beneficiaries, of Pacts for social inclusion (PaIS). This policy is the more incisive the more the services, in particular those aimed at parenting support and children aged 0-3 years, are integrated and capable of enhancing different disciplines. By contextualising the reference framework to the notion of poverty, the paper presents the three-year training experience of case managers, the practitioners provided within the Reddito di Cittadinanza and involved in the co-construction, together with the beneficiaries, of the PaIS. The paper focuses on the Project work carried out during the course, highlighting its consistency with the theoretical and methodological framework of the Reddito di Cittadinanza, and the ability to respond to the challenges of educational poverty, in terms of participation of families with children from zero to three years old, integration and multidisciplinarity of services, planning, and precocity of interventions.

CFD Analysis on Marine Propeller with Various Geometrical Conditions
Authors: N. Shalom
Published: July 2023

Computational fluid dynamics (CFD) modelling of a flow field surrounding marine propellers is difficult due to complex geometry and rotational effects. A propeller is a kind of fan that converts rotational motion to thrust to convey power. A difference in pressure is created among the front and back surfaces of an airfoil-shaped blade as well as the fluid accelerates back of the blades, producing two forces: one on the longitudinal direction of the ship, known as the thrust force, and the other, known as the tangential force, that produces the required torque. For the vast majority of parts, maritime propellers are made from aluminium or bronze alloys. In this study, a performance comparison is done between the original and modified blade version. SOLIDWORKS 2016 is used for propeller design, while ANSYS 2019 is used for structural analysis. The primary aim is to increase the rate of thrust force with a modified design and a constant input power. This study also implements cost estimation along with cost-cutting strategies. An effective cost-estimating framework can help you gain a competitive edge.

Published: July 2023

Sustainable oxidation protocols aim to provide an environmentally friendly and cost-effective method for the production of various chemicals and materials. The development of such protocols can lead to reduced energy consumption, fewer harmful byproducts, and increased efficiency in industrial processes. As such, this field of research is of great importance and interest to both academia and industry. This work showcases a sustainable and catalyst-free oxidation method for heteroatoms (e.g., S, P, and Se) using only air, water and light. An additional reaction pathway is proposed in which the incorporated oxygen on the heteroatoms originates from water. Furthermore, the addition of certain additives enhances productivity by affecting kinetics. The industrial potential is demonstrated by conveniently transferring the batch protocol to continuous flow using the HANU flow reactor, indicating scalability and improving safety.

We present photometric and spectroscopic data for the nearby Type I supernova (SN Ia) 2019eix (originally classified as an SN Ic), from the day of its discovery up to 100 days after maximum brightness. Before maximum light, SN 2019eix resembles a typical SN Ic, albeit lacking the usual O i feature. Its light curve is similar to the typical SN Ic with decline rates (ΔM
15,V
= 0.84) and absolute magnitude M

V
= −18.35. However, after maximum light, this SN has unusual spectroscopic features, a large degree of line blending, significant line blanketing in the blue (λ < 5000 Å), and strong Ca ii absorption features during and after peak brightness. These unusual spectral features are similar to models of subluminous thermonuclear explosions, specifically double-detonation models of SNe Ia. Photometrically, SN 2019eix appears to be somewhat brighter with slower decline rates than other double-detonation candidates. We modeled the spectra using the radiative-transfer code TARDIS using SN 1994I (an SN Ic) as a base model to see whether we could reproduce the unusual features of SN 2019eix and found them to be consistent with the exception of the O i feature. We also compared SN 2019eix with double-detonation models and found them to best match the observations of SN 2019eix, but failed to reproduce its full photometric and spectroscopic evolution.
FacetClumps: A Facet-based Molecular Clump Detection Algorithm
Authors: Jiang Yu , Chen Zhiwei , Zheng Sheng , Jiang Zhibo , Huang Yao , Zeng Shuguang , Zeng Xiangyun , Luo Xiaoyu
Published: July 2023

A comprehensive understanding of molecular clumps is essential for investigating star formation. We present an algorithm for molecular clump detection, called FacetClumps. This algorithm uses a morphological approach to extract signal regions from the original data. The Gaussian facet model is employed to fit the signal regions, which enhances the resistance to noise and the stability of the algorithm in diverse overlapping areas. The introduction of the extremum determination theorem of multivariate functions offers theoretical guidance for automatically locating clump centers. To guarantee that each clump is continuous, the signal regions are segmented into local regions based on gradient, and then the local regions are clustered into the clump centers based on connectivity and minimum distance to identify the regional information of each clump. The experiments conducted with both simulated and synthetic data demonstrate that FacetClumps exhibits great recall and precision rates, small location error and flux loss, and a high consistency between the region of detected clump and that of simulated clump, and the experiments demonstrate that FacetClumps is generally stable in various environments. Notably, the recall rate of FacetClumps in the synthetic data, which comprises 13CO (J = 1−0) emission line of the MWISP within 11.°7 ≤ l ≤ 13.°4, 0.°22 ≤ b ≤ 1.°05, and 5 km s−1 ≤ v ≤ 35 km s−1 and simulated clumps, reaches 90.2%. Additionally, FacetClumps demonstrates satisfactory performance when applied to observational data.

0) for the moderately volatile element rich, andesitic meteorite Erg Chech 002 (EC002). Our Al–Mg isochron defines a 26Al/27Al initial ratio of (8.65 ± 0.09) × 10−6 that corresponds to a 26Al/27Al ratio of

× 10−5 for the parent body precursor at the time of solar system formation. Whereas the published bulk chemistry and our high-precision Ca isotope measurement correspond to those for inner solar system materials, the 26Al/27Al ratio overlaps that for outer solar system CI chondrites. This indicates that the carriers and/or processes responsible for the nucleosynthetic isotope compositions for inner and outer disk materials are different than those controlling the heterogeneous distribution of 26Al. A low μ
26Mg* initial value of −6.1 ± 1.7 ppm infers a source region with a subchondritic Al/Mg ratio until 1.1 Myr after t
0 such that melt generation must have immediately preceded its crystallization. With 26Al as the main heating source, a modeled temperature–time path for a 100 km radius parent body with our inferred 26Al abundance suggests that accretion must have occurred before 0.5 Myr after t
0 to reach melting temperatures at appropriate depths within 1.1 Myr. This requires that the parent body formed very early within the protoplanetary disk, consistent with predictions of rapid formation of planetesimals by streaming instabilities within high-density dust filaments during the earliest phase of the protoplanetary disk. Finally, an absence of initial Pb in this otherwise moderately volatile-rich achondrite implies Pb was effectively sequestered to the Fe–Ni core.

Two new species of Sminthurididae,Sphaeridia piauiensisMedeiros & Bellini,sp. nov.andDenisiella piracurucaensisSilva, Medeiros & Bellini,sp. nov.from Piaui state, Brazil, are herein described and illustrated.Sphaeridia piauiensissp. nov.resembles species of theirmlerigroup, likeS. irmleriBretfeld & Gauer,S. fibuliferaBretfeld & Gauer, andS. peruensisBretfeld & Schulz, by its complex male ventral tube without asymmetrical structures or medial process. However, it differs from them by the combination of the male tibiotarsus III with a leaf-shaped IIpe chaeta and a regular IIIpi chaeta, ventral tube with 1+1 chaetae, and the absence cuticular hooks on the furca.Denisiella piracurucaensissp. nov.resembles its congeners without the nasal organ, especiallyD. colombianaOspina & Palacios-Vargas, by the presence of spiniform chaetae at least on the second antennal segment of the females, four serrated spines on tibiotarsus III, and the ventral dens chaetotaxy, butD. piracurucaensissp. nov.differs from the latter especially by the presence of 8+8 eyes and the shape of the male proximal tibiotarsal organ. To describe both species all NeotropicalSphaeridiaand all describedDenisiellaspecies were surveyed, presenting notes on both genera, comparative tables, and keys for these taxa.
Role Identity Transition: A Conceptual Framework for Being the Spouse of a Person With Early Onset Dementia
Authors: Binford Sasha , Wallhagen Margaret I. , Leutwyler Heather
Published: July 2023

Informal caregivers of persons with early onset dementia (PWEOD) are usually the spouses of affected individuals. These caregivers face unique challenges related to the unexpected nature of disease onset at this early life stage along with the accompanying symptoms, which can be different from those in late onset dementia. The current study explores the meanings these caregivers make of their situations and actions in response to their experiences. Findings provide a basis for development of a conceptual framework illustrating the basic, psychosocial processes underlying their shared situation. Grounded theory methodology was used. Qualitative data were collected through semi-structured interviews with 15 participants. Data were analyzed using constant comparative techniques and situational analysis. A distinction was made across participants between identifying as spouse versus caregiver for their PWEOD. Each participant had made or was making an identity transition from viewing their role as becoming more caregiver-like toward an eventual, complete shift to that of caregiver in a stepwise fashion. Incremental shifts in identity reflected challenges to the notion held of what it means to be a spouse. Results support prior research highlighting the unique experiences of caregivers of PWEOD while providing a framework for understanding the unique situations of these care-givers. Findings also inform nursing interventions tailored for spouses of PWEOD. [

Critical Reflections on ChatGPT in UAE Education: Navigating Equity and Governance for Safe and Effective Use
Authors: Abu Khurma Othman , Ali Nagla , Hashem Reem
Published: July 2023

Purpose: This study aims to critically review the new AI-based tool ChatGPT in UAE education and evaluate its impact on students and their learning. The study maintains a specific focus on the issues of equity and governance to allow educators in UAE to ensure that the AI-based tool is used ethically, and safely and does not restrict students’ academic development. Design/methodology/approach: This paper is a conceptual paper presenting the critical reflection of authors working in the Emirates College of Advanced Education in UAE (Author 1: Dr. Othman Abu Khurma, Author 2: Dr. Nagla Ali, and Author 3: Dr. Reem Hashem). Consequently, the study reflects the authors’ evaluation of the issues of equity and governance that maximize the potential benefit of how ChatGPT is used by students in UAE schools and higher education institutions and their thoughts on how it might be improved. Findings: The findings of this study indicate that there are both benefits and drawbacks associated with the use of ChatGPT. The authors made some recommendations to the educators in UAE regarding the ethical and fair use of ChatGPT which does not hinder student learning. Practical implications: The findings of this reflective study can raise educators’ and policymakers’ awareness regarding the potential risks and benefits of the use of ChatGPT by students. Moreover, the study offers guidance to educators and policymakers in UAE to ensure ethical and effective learning and the safe adoption of this and similar AI-tools by students. Originality/value: The study is a critical reflection of the equity and governance issue related to the use of ChatGPT by students and offers new practical insights regarding how ChatGPT can be adopted safely by students in UAE. The reflection is based on a conceptual analysis of authors’ personal and professional experiences and test usage and is thus different from previous studies.
The Therapeutic and the Transgressive: Chinese Fansub Straddling between Hollywood IP Laws and Chinese State Censorship
Authors: Zhu Ying
Published: July 2023

Fansub has played a significant role in recent years in introducing otherwise unavailable foreign AV content to China via file transfer on pirate websites that bypass or play cat-and-mouse games with both regulators and copyright holders. Fansub further provides opportunities for participants to preserve the integrity of the source content that challenges mainstream conventions and values. This article provides an overview of fansubbing in China and discusses the complex issues involving international IP law, China’s selective compliance with such laws, and the Chinese government’s censorship of media and entertainment content. Specifically, the article traces the evolution of Chinese piracy of Hollywood film and television from counterfeit to fansub to tease out the larger issues of access, advocacy, and copyright infringement. Neither the legal nor the political hazard has deterred die-hard fansubbers from their “transgressions.” In discussing fansub motivations, the article further examines both the transgressive and affirmative experiences of Chinese fansub through the lens of the therapeutic effects.
Auguste en pharaon à Kôm Bahigأغسطس كفرعون في كوم بهيج
Authors: Queyrel François
Published: July 2023

Découverte en 2022 dans la fouille menée par le Centre d’Études Alexandrines à Kôm Bahig, une tête coiffée d’un némès avec uræus vient d’une statue-pilier en basalte qui devait se dresser aux abords du dromos du sanctuaire. Les mèches frontales reproduisent le dessin du type de Prima Porta, le plus fréquent dans l’iconographie d’Auguste. Ce nouveau portrait d’Auguste en pharaon est postérieur à 27 av. J.-C., date d’adoption du type, et peut dater du règne du princeps.
Reisner and Mace’s Excavations of Naga ed-Deir Cemeteries N500–N900, N1500, N3000 and N3500 Reconsideredإعادة النَّظر في أعمال التنقيب التي قام بها رايزنر وميس في مجموعات مقابر نجع الدير N500-N900 ،N1500 ،N3000 ،N3500

Naga ed-Deir is located on the east side of the Nile, opposite Reqaqna, Beit Khallaf, and el‑Mahasna, and about 20 kilometres north of Abydos. In 1901-1904 the Phoebe A. Hearst Egyptian Expedition, led by George A. Reisner, carried out extensive excavations in several cemeteries across the site, leading to the discovery of tombs from the Predynastic period up to the early Coptic period. Amongst these were cemeteries N500–N900, N1500, N3000 and N3500, for which Reisner and Arthur C. Mace identified the typo-chronological tomb development between the 1st and 4th Dynasty. A combined study of the tombs, burial customs and material culture, especially the pottery, found in these cemeteries, however, suggests that Reisner and Mace’s dating and hence some of their conclusions are in need of revision, highlighting the need for a complete re-analysis of extant site data and museum objects.

To deal with the problems of occurring personalized music recommendation methods, for instance, low explanation, low accuracy of recommendation, and difficulty extracting information effectively, a personalized music recommendation method combining TextCNN and attention is proposed. Firstly, TextCNN model and BERT are combined to capture local music continuous features. Secondly, self-attention is introduced to solve the remaining omitted non-continuous features that are not paid attention by TextCNN. Finally, multi-headed attention mechanism is used to get features of hotspot music and user's interest music, and cascading fusion method is used to achieve click prediction. Experimentally, the proposed model can effectively recommend personalized music, its MAE values on FMA and GTZAN datasets are 0.156 and 0.146, respectively, improving by at least 6.6% and 3.3% compared to other comparative models. And its RMSE result values on the FMA and GTZAN datasets are 0.185 and 0.164, respectively, improving by at least 12.4% and 5.2% compared to other comparative models.
