Published: July 2024

Die rapide voranschreitende digitale Transformation unserer Gesellschaft und der damit verbundene Anpassungsdruck aller gesellschaftlichen Teilgebiete stellt unser Bildungssystem vor grosse Herausforderungen. Der universitären Lehrkräftebildung kommt aufgrund ihrer enormen pädagogischen Reichweite in der Beeinflussung gesellschaftlicher Anpassungsprozesse eine herausragende Rolle bei der Bewältigung dieser Herausforderungen zu. Wissenschaftlich fundierte Kompetenzmodelle, die einen umfassenden Blick auf die von Lehrkräften zu entwickelnden digitalisierungsbezogenen Kompetenzen ermöglichen, liegen bereits vor (z. B. integratives Modell der Universität Duisburg-Essen [UDE-Modell]). Deren flächendeckende Implementierung in die aktuelle Lehre lässt jedoch noch auf sich warten. Digitalisierungsbezogene Anteile der angebotenen Lehrveranstaltungen sind häufig nicht transparent, und den Studierenden fehlt es an Hilfsmitteln, ihr eigenes Kompetenzniveau bzw. dessen Progression systematisch zu erkennen und darzustellen. Dieser Artikel beschreibt ein Konzept, das den Studierenden durch eine digitale Portfolioarbeit die Möglichkeit gibt, ihren Kompetenzerwerb seminarbegleitend zu dokumentieren. Das wesentliche Forschungsinteresse galt dabei zunächst der Frage, inwieweit sich das digitale Portfolio aus der Perspektive der Studierenden als konstruktiv erwiesen hat. In einem Ausblick werden vor dem Hintergrund der gewonnenen Erkenntnisse Entwicklungspotenziale und Forschungsdesiderate aufgezeigt.

Objective: To explore regional differences (i.e. Europe, Asia and others) in the wellbeing of para-athletes and its potential psychosocial determinants, including the Athletic Identity Measure Scale (AIMS), the Brief Resilience Scale (BRS) and the Satisfaction with Life Scale (SWLS). Methods: The study was a cross-sectional survey using data from multinational badminton federations. The study participants were athletes registered in the Para Badminton Classification Master List of the Badminton World Federation (BWF). The main study outcome is the WHO Quality of Life-Disability Questionnaire (WHOQOL-DIS). Results: There were 1,385 (aged 36 years old, IQR 18 years old) registrants on the master list. Respondents totaled 170. Only 137 (65% were males) were included in the analysis after excluding those with missing data (Europe 40%, Asia 30%, others 30%). Following the results of factor analysis, the original Athletic Identity Measure Scale (AIMS) was separated into self-identity (SI) and AIMS-modified. SI, AIMS-modified, the BRS and the Satisfaction with Life Scale (SWLS) were all scored above average. The AIMS-modified scores of Europeans were significantly lower than those of other non-Asians (U = 757.000, P < 0.05). BRS was statistically higher among those with acquired disabilities (median: 3.33) compared to those with congenital disabilities (median: 3.0) (U = 1,717.000, Z = −2.711, P < 0.05) and among Europeans (median: 3.3) compared to Asians (median: 3.0) (U = 704.500, P < 0.05). The regression model explained 32% of the variability in quality of life (QOL) with five significant predictors. The SWLS (β = 0.307, P = 0.01), BRS (β = 0.269, P = 0.01), full-time employment (β = 0.191, P = 0.05) and being female (β = 0.162, P = 0.05) all had a positive effect on QOL, but not the AIMS (−0.228, P = 0.05). Conclusion: The results show that the athletes’ resilience, satisfaction with life and identity vary across regions. Furthermore, satisfaction with life, employment and gender were found to be significant predictors of athletes’ QOL.

Background: The impact of hand strength in consideration of sedentary behaviour on diabetes management in patients with type 2 diabetes mellitus (T2DM) is unclear. The purpose of this study was to examine the impact of hand strength on HbA1c, body mass index (BMI) and body composition by group according to the duration of sedentary behaviour in Japanese patients with T2DM. Methods: In this retrospective, cross-sectional, single-centre study, hand strength standardised by bodyweight (GS) and sedentary time (ST), were obtained and analysed in a total of 270 Japanese T2DM outpatients in 2021. After dividing the patients into four categories of median values (high and low GS, and long and short ST), odds ratios (ORs) for good control of HbA1c, BMI, waist circumference (WC) and intra-abdominal fat (IAF) were investigated using logistic regression models. Results: The high GS/short ST group was found to have a significantly higher (OR = 2.01; 95% CI: 1.00, 4.03; P = 0.049) for controlled HbA1c compared with that of the low GS/long ST group. The high GS/short ST and the high GS/long ST groups had significantly higher ORs for controlled BMI, WC and IAF compared with the OR of the low GS/long ST group. In addition, the ORs were significantly increased with a positive trend in order from low GS/long ST, low GS/short ST, high GS/long ST, to high GS/short ST in all models (P < 0.001 for trend). Conclusion: Hand strength, with modest effects from sedentary behaviour, could be helpful for diabetes management in T2DM patients.

Background: Coronavirus disease (COVID-19) has affected everyone and stress-related mental health issues affect young people more than other groups, including marginalised populations. As a result of this pandemic, society is being urged to examine indigenous psychological resilience, especially among Orang Asli (OA) communities in Malaysia. Hence, this study aims to identify factors associated with psychological resilience among OA youths of Kampung Orang Asli (KOA) in Gombak during the COVID-19 pandemic. Method: A cross-sectional study comprising OA communities was conducted between January 2022 and September 2022 in the Gombak District, Selangor. A self-administered online questionnaire using Google Forms and a self-administered printed questionnaire was used to collect data from youths aged 18 years old–24 years old. The Malay version of Conner-Davidson Resilience Scale-25 (CD-RISC-25) was used to assess psychological resilience. Data analysis was performed using SPSS version 28.0, and multiple linear regression analyses were conducted to evaluate the associated factors and their significance level. Result: A total of 158 participants were involved in this study. The mean score for psychological resilience was estimated at 69.28 (SD = 14.52). The social relationships domain recorded the highest mean score for quality of life (71.54, SD = 13.72). Meanwhile, the total mean score for self-esteem fell into the high-level category (35.77, SD = 4.94), and the domain of relationship and family dynamics under family environment scored the highest mean score of 18.83 (SD = 2.89). Psychological resilience was associated with youths of KOA Batu 12 (β = –14.274, P < 0.05), KOA Ulu Batu (β = –17.789, P < 0.05), less than four siblings (β = –6.495, P < 0.05), owner of residential property (β = –7.543, P < 0.05), high self-esteem (β = 0.612, P < 0.05) and good relationship and family dynamic (β = 1.391, P < 0.05). Conclusion: Developing interventions aimed at psychological resilience determinants may assist OA youths in coping with future threats.

Background: Often, the indirect impact of autism spectrum disorder (ASD) presents the family with significant challenges. One of these challenges is affiliate stigma due to parental affiliation with their child. This study aimed to explore affiliate stigma, resilience and quality of life (QoL) among parents of children with ASD. Methods: Cross-sectional study of 144 parents of children with ASD were recruited from two main tertiary hospitals in Kelantan, Malaysia, a developing country in Southeast Asia. Pearson correlation was used to examine the relationship between parental affiliate stigma, resilience and QoL. Simple and multiple linear regression analyses were used to identify the significant associated factors of affiliate stigma, resilience and QoL. Results: Correlational analyses revealed that perceived affiliate stigma demonstrated an inverse relationship with resilience and QoL. Additionally, resilience had a positive relationship with QoL. Regression analyses revealed that the father’s employment status, the mother’s level of education, having a disability card, the child’s age at ASD diagnosis, comorbidities of the child and ASD severity perceived by parents were associated with parental affiliate stigma, resilience and QoL. Conclusion: Study findings highlight the contribution of socio-demographic characteristics of children with ASD and their families in the determination of affiliate stigma, resilience and QoL.

Background: This study sought to compare the prevalence of underweight and overweight among ever-married, non-pregnant women of reproductive age in Bangladesh by urban or rural residency status. Methods: This study used Bangladesh Demographic and Health Survey (BDHS), 2017 data. Cross-sectional study design with two-stage stratified sampling method was employed. A sample of ever-married non-pregnant women of reproductive age was selected and multinomial logistic regression was utilised in analysis. Results: It was found that around half of rural women (45.0%, N = 4,934) and more than half of urban women (60.3%, n = 3,913) were overweight. Nearly one in seven rural women (14.0%, n = 1,537) and 1 in 12 urban women (9.0%, n = 564) were reported as underweight. Our analyses revealed that being overweight was substantially connected with age, husband’s occupation, economic status, television access, and division for both urban and rural areas. Women from poor households were significantly more likely to be underweight than women from middle- income households for both urban (P < 0.05; OR: 1.41; 95% CI: 1.03, 1.94) and rural (P < 0.05; OR: 1.23; 95% CI: 1.04, 1.46) areas. Interestingly, women without television access both in urban (P < 0.001; OR = 0.78; 95% CI: 0.67, 0.91) and rural (P < 0.001; OR = 0.75; 95% CI: 0.68, 0.84) areas had an inverse association with overweight/obesity compared to women with television access. In both areas, women in Sylhet and Mymensingh had higher likelihood of being underweight than Barisal division. Additionally, in both residential zones, women in Sylhet had lower likelihood of being overweight than Barisal division. Conclusion: This study reveals that multiple characteristics are linked to both overweight and underweight among ever-married, non-pregnant women of reproductive age in Bangladesh. Addressing these variables should be a priority in public health efforts to combat the dual challenge of malnutrition in Bangladesh.

Having a good memory is essential for carrying out daily tasks. People cannot study, plan, remember or navigate life effectively if they are memoryless. People may be at risk when mistakes made in the past will be repeated and lessons regarding danger cannot be learned. In the community, traumatic brain injury (TBI) is common and individuals with TBI frequently have memory problems. It is crucial to study how TBI affects memory to better understand the underlying mechanism and to tailor rehabilitation for patients with a range of pathologies and severity levels. Thus, this paper aimed to review studies related to TBI’s effect on memory. This review examined recent studies to learn more regarding and comprehend the connection between TBI and memory, including short-term memory (STM), working memory (WM) and long-term memory (LTM). This will undoubtedly have a big impact on how memory problems that may arise after TBI will be addressed. Virtual reality and other technological advancements have given the medical community a new way to investigate rehabilitative therapy.

Background: Phenylephrine (PE) is one of the vasopressor used to treat hypotension during anaesthesia. The primary aim of this study was to compare the effect of prophylactic infusion and rescue bolus of PE on the haemodynamic changes during spinal anaesthesia (SA) for Caesarean section (CS) in obese parturients. Methods: A total of 74 obese parturients scheduled for elective CS under SA were randomised into two groups; Group A (n = 37) received prophylactic PE infusion starting at 50 μg min–1 and adjusted according to the given algorithm and Group B (n = 37) received 100 μg PE bolus to treat hypotension. The measured parameters were systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), the total requirement of PE and neonatal Apgar score. Results: Six patients were excluded from the analysis due to missing data and only 68 were analysed. Group A showed significantly higher SBP, DBP and MAP than Group B (P < 0.05). The requirement of PE was higher in Group A than Group B [817.7 (265.7) µg versus 360.6 (156.0) µg; P = < 0.05]. Both groups had no difference in terms of the neonatal Apgar score. Conclusion: Prophylactic PE infusion provided better haemodynamic control than therapeutic boluses in obese parturients undergoing CS under SA.

AIM. To assess chemotherapy outcomes in patients with primary mediastinal large B-cell lymphoma (PMBCL) treated at the AF Tsyb Medical Radiological Research Center from 2016 to 2023.
MATERIALS & METHODS. The analysis focused on the data from 58 patients with the morphologically verified diagnosis of PMBCL. The patients were aged 17–62 years (median 34 years), there were 39 women and 19 men. The median follow-up was 51.2 months (range 0.4–200.9 months). Depending on drug chemotherapy regimens, patients were divided into 3 groups: R-NHL-BFM-90 (n = 9), R-CHOP (n = 17), and R-MACOP-B (n = 32). Most patients (90 %) received mediastinal radiotherapy of total 30–46 Gy.
RESULTS. The 5-year overall survival in the therapy groups was 66.7 %, 88.2 %, and 100 %, respectively (p = 0.007), progression-free survival was 66.7 %, 70.6 %, and 96.9 % (p = 0.006), and event-free survival was 66.7 %, 54.7 %, and 90.6 % (p = 0.038). On the whole, the toxicity profile of chemotherapy was quite acceptable. Neither low blood values nor other adverse events essentially affected a complete implementation of chemoradiotherapy program. The intermediate outcomes were based on PET-CT data after 2–4 therapy cycles in 37 (64 %) patients. PET-CT showed that at the stage of drug chemotherapy, complete response (CR) was achieved in 27 (73 %) patients, and partial response (PR) was achieved in 4 (11 %) patients. With respect to the CR and PR criteria, there were 6 (16 %) non-responders.
CONCLUSION. PMBCL is one of extranodal lymphomas with thymic B-cells being primary source of tumor growth. PMBCL is characterized by aggressive course and extreme heterogeneity of clinical manifestations. Up to now, the first-line chemotherapy decision making in PMBCL has remained an issue with practical importance. This paper reports immediate and long-term outcomes of the program chemoradiotherapy regimen R-MACOP-B with subsequent consolidation radiotherapy. The results obtained can be termed quite satisfactory and noninferior to the data from national and international sources. Nevertheless, more effective chemoradiotherapy programs for PMBCL continue to be elaborated. In this context, immune checkpoint inhibitors as part of therapy programs seem to hold promise for the treatment of newly diagnosed PMBCL.
The origin and evolution of wide Jupiter mass binary objects in young stellar clusters
Authors: Portegies Zwart Simon , Hochart Erwan
Published: July 2024

The recently observed population of 540 free-floating Jupiter-mass objects, including 40 dynamically soft pairs, and two triples, in the Trapezium cluster have raised interesting questions on their formation and evolution. We test various scenarios for the origin and survivability of these free floating Jupiter-mass objects and Jupiter-mass Binary Objects (JuMBOs) in the Trapezium cluster. The numerical calculations are performed by direct NN-body integration of the stars and planets in the Trapezium cluster starting with a wide variety of planets in various configurations. We discuss four models: \mathcal{SPP}𝒮𝒫𝒫, in which selected stars have two outer orbiting Jupiter-mass planets; \mathcal{SPM}𝒮𝒫ℳ, where selected stars are orbited by Jupiter-mass planet-moon pairs; \mathcal{ISF}ℐ𝒮ℱ in which JuMBOs form in situ with the stars, and \mathcal{FFC}ℱℱ𝒞, where we introduce a population of free-floating single Jupiter-mass objects, but no initialised binaries. Models \mathcal{FFC}ℱℱ𝒞 and \mathcal{SPP}𝒮𝒫𝒫 fail to produce enough JuMBOs. Models \mathcal{SPM}𝒮𝒫ℳ can produce sufficient free-floaters and JuMBOs, but requires unusually wide orbits for the planet-moon system around the star. The observed JuMBOs and free-floating Jupiter-mass objects in the Trapezium cluster are best reproduced if they formed in pairs and as free-floaters together with the other stars in a smooth (Plummer) density profile with a virial radius of \sim 0.5∼0.5pc. A fractal (with fractal dimension 1.6) stellar density distribution also works, but requires relatively recent formations (⪆ 0.2⪆0.2Myr after the other stars formed) or a high (⪆ 50⪆50%) initial binary fraction. This would make the primordial binary fraction of JuMBOs even higher than the already large observation fraction of \sim 8∼8% (42/540). The fraction of JuMBOs will continue to drop with time, and the lack of JuMBOs in Upper Scorpius could then result in its higher age, causing more JuMBOs to be ionized. We then also predict that the interstellar density of Jupiter-mass objects (mostly singles with some \sim 2∼2% lucky surviving binaries) is \sim 0.05∼0.05 per pc^{-3}−3 (or around 0.24 per star).
The EU’s Indo-Pacific Strategy. Motivations, Influences, Challenges, and Implications for China
Authors: Jian Junbo ,   Fudan University, Fang Jiongsheng ,   Fudan University
Published: July 2024

The European Union’s Indo-Pacific Strategy (EU’s IPS) is one of the most important geopolitical strategies of the EU in recent years, but the motivation behind the launching of this strategy, its influence and challenges, and the possible response of China as a major Indo-Pacific power, still need further study. Using various research methods including power transition paradigm, levels of analysis approach, as well as the traditional Chinese strategic framework of upper/middle/lower scenarios, the article endeavors to offer insights into the above research questions. The motivation of EU’s IPS is the ‘Geopolitical Awakening’ to avoid the negative results of potential great power rivalry during a period of global power transition. The IPS will accelerate the identity transformation of the EU from a ‘soft’ multilateralist to a ‘hard’ pole in the multi-polarized world, increase geopolitical uncertainty in Asia, and remodel China-EU-US strategic triangle. However, the implementation of the EU’s IPS will face multiple challenges, including gap in policy orientations among member states, different concerns of Indo-Pacific partners, and the EU’s awkward position in the US IPS. The EU’s IPS could bring about three possible scenarios of China-EU interaction in this region- pure confrontation, limited cooperation, or a positive-sum game. In this context, the Chinese government could effectively manage differences with the EU in Indo-Pacific, attempt to engage with the EU and together play a more active order-shaping role for the development of the region.

The article is devoted to identifying the territorial features of youth migration in the peripheral regions of the South of European Russia on the example of the Stavropol Territory. The features of intra-regional differentiation of demographic indicators characterizing the distribution of young people are analyzed. The main tendencies of youth migration in different territories are revealed, depending on the action of push and pull factors, the typology of municipalities of the region according to migration growth and the direction of migration flows is carried out. The object of the study was the youth of the Stavropol Territory aged 15 to 29 years. The official statistics of the current accounting of the population, developed by Rosstat for the period 2012–2919, was used as an empirical basis. The materials are presented in the form of a series of tables and maps reflecting the peculiarities of territorial inequality in the course of youth migration at the regional and intra-regional levels. There is a steady downward trend in the number of young people in all territories of the region, in which migration plays a significant role. In most of its municipalities, there is a migration loss, and only in a few - a migration gain. The migration attractiveness of the Stavropol region is due to the presence of a large number of institutions of higher and secondary vocational education, including the federal university. An important role in attracting young migrants to the region is played by the ethnic factor, which provides a certain influx in international and interregional exchange. Ethnic groups from the North Caucasian republics and the states of the South Caucasus form compact areas of settlement that attract young compatriots. Youth migration processes are largely polarized. Within the Stavropol and Kavminvodsk urban agglomerations, there is a zone with a predominant increase in youth in intraregional and international migration and losses in interregional migration. The rest of the territory forms a vast periphery with a predominance of youth loss. A less dramatic decline in youth is noted in the southern border areas, which is offset by a small interregional influx.

A new digital bathymetric model of Lake Onego (Verhne-Svirskoe Reservoir) has been developed based on navigation charts. Verification of the model was carried out by comparing the modeled bathymetry with the cartographic materials, echo sounder measurements, and previous bathymetric models. Spatial resolution of the developed model is 50 m in plane and 2 m in depth. Despite these identified deviations in depth, the model has a good agreement between raster values and measured depth, which can be considered sufficient to calculate the main morphometric characteristics of the lake and solve other applied tasks. Morphometric characteristics of the water body (within the boundaries of the lake and reservoir separately) and its limnic regions were updated based on the developed digital model. In particular, values of the water area, water volume, average and maximum depth, littoral area (up to isobaths 2, 5, and 10 m) of limnic regions were specified for the first time based on the developed bathymetric model. The Central and South Onego are the largest regions by water area, while the Large Onego, the Central part of the lake and the Povenets Bay are the deepest. The largest areas of the lake in terms of the littoral area value are the Central part and the South Onego, while the maximum percentage of the littoral area was observed in the Kizhi skerriesand for most of thenorthern bays of the lake. The digital bathymetric model was applied to reconstruct the lake development in the post-glacial period, as well as in mapping the Quaternary deposits of the lake basin. The digital model can also be used as a basis for 3D modeling of geomorphologic, thermo-hydrodynamic and sedimentation processes.

In contrast to the developed areas of the Middle and Southern Urals, the hard-to-reach and eroded northern territories of the Ural folded system remain poorly studied, which determines a large number of unevaluated gold ore occurrences and single industrial objects. The Karyernoe gold ore occurrence is located among the Middle Paleozoic volcanic-clastic rocks of the Toupugol-Khanmeishorsky gold ore district on the eastern slope of the Polar Urals. The volcanic rocks show signs of early stratabound pyrite-like mineralization, which is cut by veins and dikes of the Sobsky (D1-2) and Musyur (C1-2) complexes. A new approach – (U,Th)-He pyrite dating – was used in order to determine the age of the sulfide mineralization of the Karyernoe ore occurrence, located on the flank of the Novogodnee ore field. (U,Th)-He pyrite ages (n=7) varies in a wide range from 402 to 425 Ma. Given the petrographic and mineralogical-geochemical observations, obtained data suggest the presence of at least two stages of rock mineralization: wenlock-ludlow – 424±6 Ma; and a later Early Devonian – 402±6 Ma, which is probably associated with the intrusion of Sob complex granitoids into the rocks of the Toupugolskaya formation. The obtained ages of the sulfide mineralization of the Karyernoe ore occurrence are significantly older than the age values established for large gold ore objects of the district: Petropavlovskoye and Novogodnee-Monto deposits (~382 million years). Taking into account the position of the Karyernoe ore occurrence on the flank of the Novogodnee ore field, it can be assumed that the disseminated and layered sulfide impregnation of the volcanic rocks of the Toupugolskaya formation could have acted as one of the sources of sulfur and ore metals for later stages of sulfide mineralization in the Toupugol-Khanmeishorsky district.

Published: July 2024

Goal: identify the key barriers hindering operationalization of the corporate innovation strategies (i. e. the transition from the adopted strategy to its implementation at the operational level) and define the capabilities of technology roadmaps (TRM) to overcome these barriers. Metodology: consists of two logically connected parts: 1) the comparative analysis of relevant international empirical research to identify the main issues of putting the agreed-upon corporate innovation strategies into action; 2) real case study analysis of TRMs application in the large corporate entities working as a tool to deal with the identified issues. Findings: identification and characterization of a core set of typical issues representing the most significant barriers to translate corporate innovation strategies into action; definition of the main advantages of TRMs as an effective tool for operationalization of corporate innovation strategies; the conclusions on the relevance of TRMs for developing and monitoring the programmes for innovation development of Russian companies with State participation. Originality and contribution of the authors: the novelty of the paper relates mainly to identification of significant potential and the main avenues for TRMs application in dealing with the “strategy-execution gap” in the context of innovation activities of large companies. From this perspective, it would be no less important to note that the key issues and mechanisms of integration between strategy and operationsrelated functionalities of TRMs are defined and specified.

Goal: to assess the efficiency of the Nigerian stock market after the COVID-19 lockdown which had substantial impacts on African countries, including their local stock markets. Metodology: the empirical study was conducted by employing the GARCH models with three different error distributional assumptions with data covering the timeframe from June 2020 to December 2022. Findings: the results indicate that during the post COVID-19 period, the Nigerian stock market demonstrates inefficiency in the weak form but efficiency in the semi-strong form. Originality and contribution of the authors: this is the first empirical study in Nigeria that presents the comprehensive overview of market efficiency in the post COVID-19 period. The authors’ emphasis in the study that the levels of market efficiency are independently determined forms; the semi strong form efficiency can be attained without week form efficiency. The study emphasise the importance of implementing strict oversight, restrictions, and regulations to discourage excessively negative noise (rumour) traders and investors from engaging in short selling for profit especially in equities held by institutional investors.
The impact of economic sanctions on firm performance: Perceptions of Russian SME managers
Authors: Golikova Victoria V. ,   Institute for Industrial and Market Studies, HSE University
Published: July 2024

Goal: drawing from resource-based and institutional perspectives, the Russian sanctions/countersanctions are studied as a context of enduring economic-political turbulence for small- and medium-sized enterprises (SMEs) managers following external shock for Russian economy after first wave of sanctions in 2014 which affects firm performance through resource availability changes and (enforced) adjustments of strategic resources. Metodology: logit models are estimated for 972 SMEs within the sample of more than 1 700 manufacturing firms in Russia that are no direct targets of the sanctions. Cross sectional survey data collected in 2018 are used to evaluate the sanctions’ effect represented in the perceptions of SME managers about their firm performance. Findings: sanctions decrease the value of the firms’ resource combinations and force SMEs to bear adjustment costs. SMEs that are limited in their resource availability find it burdensome to derive adjustment strategies through resource re-allocations. All else equal, the technologically advanced SMEs perceive a deteriorated performance, while SMEs with domestic and international partnerships and young firms remain more optimistic. Counter sanctions helped to mitigate the burden of deteriorated business environment. Originality and contribution of the authors: the paper contributes to understanding of sanctions’ effect for firms that are not direct target of sanctions, which amends the existing macro-level and sectoral studies on the effects of economic sanctions with a more nuanced micro-level exploration taking into account heterogeneity of firms’ response to sanctions shock.

Originality and contribution of the author: systematic analysis of Russian companies organizational culture research was carried out.
Bank-Specific Decisions and Banks’ Provisioning Behaviour in Nigeria: The Role of IFRSs Adoption and Banks’ Riskiness
Authors: Salami Abdulai A. ,   Al-Hikmah University
Published: July 2024

Goal: this study examines the relationship between bank loan loss provisioning behaviour and various bank-specific decisions on loan loss reporting. The evidence is derived from several cases of non-performing exposures of Nigerian deposit money banks. Metodology: to investigate the relationship between bank loan loss provisioning behaviour and various bank-specific decisions on loan loss reporting there was created the loan loss bank-specific decisions index (BDI) according to the International Financial Reporting Standards (IFRSs). The hypotheses are tested by using the estimates of panel corrected standard errors regression model. Findings:the results showed that discretionary adjustments to loan loss provisions (LLPV) are typical of Nigerian banks although the earnings manipulations imbedded in discretionary LLPVs (DLPV) are not factored in. However, during IFRS a reversal is evident suggesting bank-specific decisions prompting increased DLPV except for seemingly financially distressed banks. These findings also confirm the relationship between BDI components and provisioning behaviour in individual tests. The study also found out that the provisioning behaviour in Nigeria during global financial crisis was pro-cyclical (nonrational) while during the local economic recession of 2016–2017, it was counter-cyclical (rational). The latter, which happened during the IFRS period, was characterized by income smoothing while the former was addressed at the level of bank-specific decisions. Originality and contribution of the authors: the study contributes to the literature by testing a list of bank-specific factors engendering adjustments to loan loss decisions. It is unique in terms of the empirical reference to numerous bank-specific decisions as a single factor in accounting for loan losses. The paper also establishes the parochial success of institutional changes in the corporate Nigeria and offers useful suggestions for the way forward.

Published: July 2024

Avançar na formação de professores por meio de inovações em tempos de tecnologias digitais de informação e comunicação (TDIC) e interconexão digital pode ser um ato revolucionário. Nesse sentido, este artigo descreve a experiência da implementação de TDIC no estágio de docência com uma turma de Pedagogia. Utilizamos as TDIC como recursos mediadores em contexto de espaços híbridos. A questão de pesquisa é: Como foi organizada e experienciada a sequência didática em perspectiva colaborativa com estudantes no componente curricular “Pesquisa e prática pedagógica 3?” O estudo de natureza qualitativa se desenvolveu por meio do modelo lewiniano de aprendizagem experiencial. Os dados são resultados de descrições e narrativas dos pesquisadores sobre o fazer docente. Com base nas inferências desde a experiência, percebemos que as TDIC podem reduzir margens e dualidades. No entanto, as relações mediadas por tecnologias são intensificadas pela intenção afetiva, comunicacional, coordenada e interacional de corresponsabilidades entre os sujeitos.
Investigating the Association between LncRNA NR2F2-AS1, miR-320b, and BMI1 in Gastric Cancer: Insights into Expression Profiles as Potential Biomarkers for Disease Management
Authors: Ghorbanzadeh Shadi , Pourghasem Navid , Amiz Roghayeh , Afsa Masoomeh , Malekzadeh Kianoosh
Published: July 2024

Aim:

This study aims to investigate the potential role of lncRNA NR2F2-AS1 in the
development of gastric cancer by affecting the levels of miR-320b and BMI1.

Background:

Gastric cancer is a high-mortality malignancy, and understanding the underlying
molecular mechanisms is crucial. Non-coding RNAs play an important role in gene expression,
and their dysregulation can lead to tumor initiation and progression

Objective:

This study aims to determine the pathological role of LncRNA NR2F2-AS1 in gastric cancer progression and its association with the clinicopathological characteristics of patients.

Methods:

Bioinformatics databases were used to predict the expression levels and interactions between the studied factors to achieve this objective. The expression pattern of NR2F2-AS1/miR-320b/BMI1 in 40 pairs of tumor and adjacent normal tissues was examined using RT-PCR, IHC, and western blot. The correlation, ROC curve, and survival analyses were also conducted for the aforementioned factors.

Results:

The results showed an increase of more than 2-fold for BMI-1 and lncRNA NR2F2-AS1 in lower stages, and the elevation continued with the increasing stage of the disease. This correlated with significant downregulation of miR-320b and PTEN, indicating their association with gastric cancer progression and decreased patient survival. LncRNA NR2F2-AS1 acts as an oncogene by influencing the level of miR-320b, altering the amount of BMI1. A reduction in the amount of miR-320b against lncRNA NR2F2-AS1 and BMI1 directly correlates with a reduced overall survival rate of patients, especially if this disproportion is more than 3.0. ROC curve analysis indicated that alteration in the lncRNA NR2F2-AS1 level showed more than 98.0% sensitivity and specificity to differentiate the lower from higher stages of GC and predict the early onset of metastasis.

Conclusion:

In conclusion, these results suggest that NR2F2-AS1/miR-320b/BMI1 has the potential to be a prognostic as well as diagnostic biomarker for gastric cancer.
Comparison of Changes in the Neutrophil-lymphocyte Ratio (NLR) and Post-surgery Outcomes in Child Patients with COVID-19 and Non-COVID-19

Published: July 2024

Background

Pediatric patients with COVID-19 who undergo surgery have two actual problems, both the presence of a viral inflammatory response and an inflammatory response to surgery, which can affect the outcome of surgery and therapy. NLR is considered a fairly accurate predictor of surgery and COVID-19 infection.

Objective

This study aims to investigate the effect of changes in neutrophil-lymphocyte (NLR) on post-surgery outcomes in pediatric patients with COVID-19 infection.

Methods

It is a retrospective cohort study with an observational analysis. This research is a multi-center study on COVID-19 patients using a data bank of pediatric patients with COVID-19 and control patients non COVID-19 children undergoing surgery in three hospitals. Data recorded were age, gender, nutritional status, anesthetic status before surgery, length of stay, repeat surgery, sepsis, septic shock, and mortality. Statistical analysis was performed by the U-mann Whitney test.

Results

The study sample consisted of 87 total samples consisting of 2 groups, namely the group of pediatric patients with 29 samples with COVID-19 and 58 non-COVID-19 samples. Gender, nutritional status, length of stay, the incidence of reoperation, sepsis, septic shock, and mortality were not significantly different between the two groups with a p<0.05. Risk analysis by looking at the incidence of sepsis and septic shock obtained an intersection point of 2.175 and 2.225, respectively. Analysis of changes in the NLR (delta-NLR) in the mortality events of the COVID-19 group and non-COVID-19 found that the NLR of the COVID-19 group was two times greater than the cut-off NLR of 2,175.

Conclusion

There is no difference in the outcome of surgery for children with COVID-19 and non-COVID-19 based on the NLR change analysis.
