Fragment of the Great Acafist in the Foreword of Small Solbinsky Synodik
Authors:   Institute of Philology, Shadrina Evgeniya S.
Published: December 2022

The article examines a fragment of the great acafist in the foreword of Small Solbinsky Synodik. Gymnographic texts, along with texts of other genres, have traditionally been part of synodic books with literary prefaces. In the Small Synodic of Solba Nikolayev hermitage, there is a fragment, the genre of which was previously determined incorrectly. This is a fragment of the 9th ikos of Akathist of the Most Holy Theotokos. The study made it possible to put forward a hypothesis about the origin of passage as part of synodic book: it was due to the unsuitability of sheet for the akathist list due to a mistake made by the scribe. The inclusion of the fragment does not contradict the genre peculiarities of synodiс and akathist. The passage naturally fit into the group of synodic texts and became an allusion to traditional theological parallels in the spirit of “eschatological optimism:” death is the mysterious birth into eternal life, virginity after Christmas is life after death, Incarnation is the beginning of abolition of death, the salvation of man. The fragment of Akathist is considered in the context of other synodic prefaces and hymnographic texts.
Holy Sepulchre through the Eyes of Old Russian Pilgrims of the 12th–17th Centuries
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Kirillin Vladimir M.
Published: December 2022

The article considers the descriptions of Kuvuklion, the main Christian memorial, which are contained in Old Russian travel notes compiled by Russian pilgrims who visited Jerusalem from the 12th to the 17th centuries. The comparison of these descriptions with each other, as well as partly with similar descriptions of Greek pilgrims and Western pilgrims, reveals the specifics of attitude of Russian travelers as observers and storytellers to the described holy relic. The latter, with varying completeness and degree of attention to particulars, but methodically sought to create a visual image of the Kuvuklia in the imagination of their readers, to develop a more or less clear, objectively detailed idea of it, remaining in the exclusively business discourse in stylistic terms, which in no way reflects spiritual and emotional experiences and aesthetic impressions, which could well color their perception at the moment of direct communion with shrine. Accordingly, the goals of their appeal to readers as a verbal presentation of a specific subject phenomenon in the Holy Land without any expression about it, which was probably considered superfluous, were determined by the same restrained business nature. At the same time, when comparing the texts, it is found that the expression “Holy Sepulcher” was originally used polysemically in the wide speech space of Middle Ages, gradually acquires a more specific meaning, which is undoubtedly a reflex of a certain speech development.

Published: December 2022

The COVID-19 outbreak is considered as one of the most severe infectious viruses experienced by the world during the 21st century. This pandemic has economic, social, and psychological consequences on all countries, so the main purpose of this paper is to determine the impact of COVID-19 on the Egyptian stock return specifically as Egypt has been one of the countries that were strongly affected. The impact of COVID-19 on the Egyptian Stock Exchange (EGX100) was investigated using a multiple regression model and historical data from 20 listed firms in the EGX100 index between February 2020 and March 2022. Additionally, we included inflation as a control variable in our model. The results indicated that COVID-19 significantly impacted the stock’s cumulative returns when used as an independent variable and measured using the cumulative coronavirus cases (CCC) and cumulative coronavirus deaths (CCD) collected for the time period of February 2020 through March 2022 from the World Health Organization (WHO) database. The findings also showed a negative correlation between these elements and the cumulative returns of the stock. Furthermore, The outcome of our model also showed that there was no significant relationship between inflation as measured by headline CPI and the stock’s cumulative returns

Authors: Galanis Stergios , Pazarskis Michail , Kourtesi Sofia , Gatziou Maria
Published: December 2022

Corporate governance plays a key role for the companies of the private sector, and recently corporate governance started to be involved within the structures and activities of public entities and state-owned enterprises (SOEs). Many countries, including Greece, have put regional and municipal merger plans into place in order to reduce costs and enforced the ideals of economy, efficiency, and effectiveness in public administration. This study, focusing on these issues, illustrates the current state of Greek governance and recent legal developments after the merging of local government organizations (LGOs) and their associated municipal and regional-owned companies (SOEs) and provides new insights and conclusions regarding the implantation of governance in the LGOs and their SOEs after mergers
CUSTOS CONSIDERADOS NA ESCOLHA DAS MODALIDADES DE GERENCIAMENTO DE RESULTADOS: ESTUDO EMPÍRICO EM EMPRESAS LISTADAS NA B3
Authors: Da Silva Marques Jaqueline , Ramos Felipe
Published: December 2022

O estudo verifica quais custos associados influenciam a escolha (trade-off) de uma prática de gerenciamento de resultados (GR), em detrimento de outra, pelas empresas. Para tanto, realizou-se um estudo empírico com as empresas brasileiras de capital aberto listadas na B3 no período 2008-2017, desenvolvido em duas etapas. Na primeira, foram estimados os níveis de custos de produção considerados normais, despesas discricionárias e accruals, seguindo a metodologia proposta por Roychowdhury (2006) e Jones modificado (Dechow et al., 1995). Na segunda etapa, seguindo Zang (2012), os resíduos dos modelos propostos fizeram parte das múltiplas regressões estimadas em painel, para avaliar o efeito dos custos de cada modalidade de gerenciamento. Os dados foram obtidos via plataforma Economática, sendo tratados no software Stata. Os resultados indicam que as empresas auditadas por Big4 tendem a incorrer menos em GR baseado em accruals e que empresas consideradas líderes no segmento em que atuam engajam-se mais em manipulação por atividades reais. Não foi possível confirmar que, em função de seu status pouco competitivo no setor, empresas não líderes usam mais GR por accruals. Por outro lado, condição financeira menos saudável é determinante para gerenciamento por accruals. Além disso, os resultados indicam uma relação substitutiva entre manipulação de atividades reais e GR por accruals. O nível desse último está negativamente relacionado com o valor inesperado do primeiro, realizado no final do exercício social.
O TESTE DE IMPAIRMENT MENTE? O CASO DOS ATLETAS DOS CLUBES DE FUTEBOL BRASILEIROS
Authors: Krauspenhar João Henrique , Rover Suliani
Published: December 2022

A partir de indícios de problemas na realização do teste de impairment de atletas pelos clubes de futebol brasileiros, este estudo analisa a evidenciação, mensuração e reconhecimento da recuperabilidade do ativo atletas nessas entidades. Por meio de uma amostra composta por 198 observações, do período entre 2013 e 2019, de 34 clubes de futebol integrantes das séries A e B do campeonato brasileiro no ano de 2019, mensura um nível de evidenciação do teste de impairment insatisfatório (44,46%), porém satisfatório em relação ao reconhecimento de perda (76,19%), nas observações em que esta ocorreu. Quanto ao nível do reconhecimento de impairment, identificou-se grande variação entre as observações pertinentes, destacando-se a importância da divulgação de informações pelos clubes para sua compreensão. A estimativa de recuperabilidade dos atletas, realizada no nível dos planteis, aponta que seu valor de registro é predominantemente recuperável, tendo apenas seis observações apresentado indícios de impairment não reconhecido. Análise complementar dos atletas isolados indica que 12 de 18 observações possuem ao menos um atleta com indícios de impairment não reconhecido. Os resultados atualizam e estendem a literatura a respeito do tema, explicando o contraste no reconhecimento de impairment entre a realidade brasileira e europeia ao indicar a inobservância da norma contábil pelos clubes de futebol brasileiros.  Por outro lado, aponta que o baixo nível de reconhecimento de impairment se justifica ao ser considerado o valor dos planteis, provocando debate a respeito da norma contábil.

Authors: Peschel Dominik , Liu Wenyu
Published: December 2022

This paper examines the economic growth prospects of the People’s Republic of China (PRC). To increase potential growth, it suggests reforms in four areas—labor, education and training, capital, and productivity. Economic growth in the PRC has moderated over the past decade, a trend exacerbated by the pandemic. This paper estimates the level of economic growth to which the country should be able to return after the pandemic. More broadly, it looks at the PRC’s long-term growth prospects given its rapidly aging society, a high dependence of growth on investment, and a changed international environment.

Published: December 2022

The increasing threat landscape in Industrial Control Systems (ICS) brings different risk profiles with comprehensive impacts on society and safety. The complexity of cybersecurity risk assessment increases with a variety of third-party software components that comprise a modern ICS supply chain. A central issue in software supply chain security is the evaluation whether the secure development lifecycle process (SDL) is being methodologically and continuously practiced by all vendors. In this paper, we investigate the possibility of using a decentralized, tamper-proof system that will provide trustworthy visibility of the SDL metrics over a certain period, to any authorized auditing party. Results of the research provide a model for creating a blockchain-based approach that allows inclusion of auditors through a consortium decision while responding to SDL use cases defined by this paper. The resulting blockchain architecture successfully responded to requirements mandated by the security management practice as defined by IEC 62443-4-1 standard.
Supporting 5G service orchestration with formal verification
Authors: Backeman Peter , Kunnappilly Ashalatha , Seceleanu Cristina
Published: December 2022

The 5G communication technology has the ability to create logical networks, called network slices, which are specifically carved to serve particular application domains. Due to the mix of different application criticality, it becomes crucial to verify if the applications? service level agreements are met. In this paper, we propose a novel framework for modeling and verifying 5G orchestration, considering simultaneous access and admission of new requests to slices as well as virtual network function scheduling and routing. By combining modeling in userfriendly UML, with UPPAAL model checking and satisfiability-modulo-theories based model finding, our framework supports both modeling and formal verification of service orchestration. We demonstrate our approach on a e-health case study showing how a user, with no knowledge of formal methods, can model a system in UML and verify that the application meets its requirements.

Published: December 2022

Conventional electronic Artificial Neural Networks (ANNs) accelerators focus on architecture design and numerical computation optimization to improve the training efficiency. However, these approaches have recently encountered bottlenecks in terms of energy efficiency and computing performance, which leads to an increase interest in photonic accelerator. Photonic architectures with low energy consumption, high transmission speed and high bandwidth have been considered as an important role for generation of computing architectures. In this paper, to provide a better understanding of optical technology used in ANN acceleration, we present a comprehensive review for the efficient photonic computing and communication in ANN accelerators. The related photonic devices are investigated in terms of the application in ANNs acceleration, and a classification of existing solutions is proposed that are categorized into optical computing acceleration and optical communication acceleration according to photonic effects and photonic architectures. Moreover, we discuss the challenges for these photonic neural network acceleration approaches to highlight the most promising future research opportunities in this field.

The conceptual design of information systems is mandatory in several application domains. The advent of the Internet of Things (IoT) technologies pushes conceptual design tools and methodologies to consider the complexity of IoT data, architectures, and communication networks. In agroecology applications, the usage of IoT is quite promising, but it raises several methodological and technical issues. These issues are related to the complexity and heterogeneity of data (social, economic, environmental, and agricultural) needed by agroecology practices. Motivated by the lack of a conceptual model for IoT data, in this work, we present a UML profile taking into account different kinds of data (e.g., sensors, stream, or transactional) and non-functional Requirements. We show how the UML profile integrates with classical UML diagrams to support the design of complex systems. Moreover, We prove the feasibility of our conceptual framework through a theoretical quality assessment and its implementation in the agroecology case study concerning the monitoring of autonomous agricultural robots.

Authors: Özdemir Betül , Canikoglu Nuray
Published: December 2022

In this study, zirconium nitride (ZrN) powders were prepared using zirconium
oxide (ZrO2) and carbon black via the dynamic thermochemical method, called
the dynamic carbothermal reduction and nitridation (DCRN) method. The
effects of process temperatures on phase transformation and produced powder
morphologies in a dynamic system under flowing nitrogen atmosphere were
investigated by X-ray diffraction, scanning electron microscopy and energy
dispersive spectroscopy. For this purpose, the various test parameters were
investigated, such as reaction temperatures (1400, 1450, 1500?C), reaction
time (1, 2, 3 h) and rotation rates (2, 4, 6 rpm). The results show that ZrN
powders of sub-micron size can be obtained at 1500?C for 1h and 4 rpm by
the dynamic thermochemical method.

Published: December 2022

High colour rendering bismuth vanadate (BiVO4) pigments were successfully
synthesized by self-propagating combustion method at low temperature (200?C). Interestingly, the addition of citric acid as a fuel was beneficial to
the formation of well-dispersed olive-like BiVO4 particles with the size
around 730 nm. Furthermore, the as-prepared pigments also exhibited high
purity m-BiVO4 phase and brilliant yellow hue (b* = 78.12), which is better
than that of previously reported in literature and commercially available
BiVO4 yellow pigments. Importantly, the pigments were applied in various
substrates (PMMA, glass and ceramics), and showed excellent colour
rendering, dispersion properties, thermal and chemical stability, indicating
its potential application in the high-grade plastic, glass and ceramic-ware
decoration.

Authors: Yuan Xiaokun , Ji Yuan
Published: December 2022

This paper reports the interdisciplinary approach of simultaneous use of a
stereological method, namely the five parameter analysis (FPA) method and
the grain boundary character distribution (GBCD) in cemented carbides. There
are six major aspects: i) the background and motivations of the
interdisciplinary approach, ii) the principle of the FPA method, iii)
orientation texture of boundary planes with specific misorientations via
?(?g, n) mode in cemented carbide, iv) orientation texture of habit planes
regardless of misorientations via ?(n) mode in cemented carbide, v)
application of the FPA method to serial cemented carbide samples and vi)
boundary sort methods before using the FPA method. The work aims at
presenting beneficial reference for studying structural and distribution
features of special coincidence site lattice (CSL) boundaries in a
statistical manner, and in turn increasing the knowledge about the
structure-property relationship in cemented carbides.
Investigation of mechanical properties and stored elastic energy-fragmentation of Al2O3-Cr2O3 ceramic system with increasing Cr2O3 content
Authors: Kafkaslıoğlu Yıldız Betül , Tür Yahya
Published: December 2022

In the present study, densification, mechanical properties (elastic modulus,
hardness, flexural strength) and stored elastic energy-fragmentation of the
pure Al2O3 and Al2O3-Cr2O3 ceramics with different Cr2O3 volume content
(0.5, 1, 3, 5, 10 and 20 vol.%) were investigated. The fragmentation
behaviour was interpreted from the point of armour application as larger
fragments are required for higher penetration resistance. The equibiaxial
flexural strength test method was used to measure the fracture strength
values. A similar densification behaviour was obtained for the pure Al2O3
and the Al2O3-Cr2O3 ceramic specimens with 0.5, 10 and 20 vol.% Cr2O3 with
the obtained relative densities of around 97%TD. The elastic modulus of the
pure Al2O3 and Al2O3-Cr2O3 ceramic specimens showed consistent values with
the densification except for the Al2O3-Cr2O3 ceramics containing 20 vol.%
Cr2O3. All Al2O3-Cr2O3 ceramics have lower flexural strength values than the
pure Al2O3. The pure Al2O3 had the smallest crack surface area accompanying
the largest fragment size for given fracture energy. This indicates that the
pure Al2O3 will break into larger pieces in case of a possible impact.

Authors: Ussui Valter , Lazar Dolores Ribeiro , de Lima Nelson , Arata Anelyse , Ribeiro Fabio , Dalpian Gustavo , Marchi Juliana , Paschoal José Octavio
Published: December 2022

Yttria-stabilized tetragonal zirconia (Y-TZP) ceramics have excellent
mechanical properties. However, such materials cannot undergo plastic
deformation at room temperature due to their high hardness and brittleness
values, hindering machinability. To overcome these limitations, we propose a
zirconia-yttria-titania ceramics, based on zirconia containing 3mol% yttria
and up to 15mol% titania. The zirconia-yttria-titania powders were
synthesized by co-precipitation method, uniaxially pressed and sintered at
1400?C/5 h. Sample characterizations were carried out by X-ray diffraction,
scanning electron microscopy and mechanical properties through Vickers
hardness and toughness measurements. Compared to the Y-TZP ceramics, the
yttria stabilised tetragonal zirconia ceramics co-doped with 10mol%Ti showed
noticeable increase of tetragonality parameter, higher toughness and lower
hardness values, indicating plasticity at room temperature. Furthermore, the
atomistic simulation by Density Functional Theory methodology suggests the
occurrence of spatial arrangement of the atoms, explaining the proposed
plasticity.
Optimization of La0.6Sr0.4Co0.2Fe0.8O3-α - Ba(Ce0.6Zr0.4)0.9Y0.1O3-δ cathode composition for proton ceramic fuel cell application

Published: December 2022

Composite cathodes consisting of different compositional ratios of
La0.6Sr0.4Co0.2Fe0.8O3-? (LSCF) and Ba(Ce0.6Zr0.4)0.9Y0.1O3-? (BCZY64),
namely 100LSCF:0BCZY64 (L10B0), 70LSCF:30BCZY64 (L7B3), 50LSCF:50BCZY64
(L5B5) and 30LSCF:70BCZY64 (L3B7) were prepared via wet chemistry method.
The symmetrical cell with a configuration of electrode|BCZY64|electrodewas
fabricated using dry-pressingmethod for the electrolyte substrate and
spin-coating technique for the cathode layer. The proton conduction in the
composite cathode increases as the amount of proton-conducting phase
increases as verified by the water uptake measurement performed via
thermogravimetric analysis. The thickness of the composite cathode layer is
about 15 ?m as observed by a scanning electron microscope and exhibits a
well-connected particle network with sufficient porosity for oxidant
diffusion (20-30%). The electrochemical performance of the symmetrical cell
was investigated by electrochemical impedance spectroscopy in humidified
air. The area-specific resistance (ASR) values of the tested cathodes follow
the order of L7B3 < L10B0 < L5B5 < L3B7 and are 0.07 < 0.24 < 0.30 <
0.52W?cm2 at 700?C, respectively. The correlation between the cathode
performance and cathode composition was investigated and the corresponding
mechanism was systematically postulated.
Mitochondrial Genome–Encoded Long Noncoding RNA and Mitochondrial Stability in Diabetic Retinopathy
Authors: Kumar Jay , Mohammad Ghulam , Alka Kumari , Kowluru Renu A.
Published: December 2022

Mitochondria experience genomic and functional instability in diabetes, and mitochondrial dysfunction has a critical role in the development of diabetic retinopathy. Diabetes also alters expressions of many long noncoding RNAs (LncRNAs), the RNAs with >200 nucleotides and no open reading frame. LncRNAs are mainly encoded by the nuclear genome, but mtDNA also encodes three LncRNAs. Our goal was to investigate the effect of hyperglycemia on mtDNA-encoded LncRNA cytochrome B (LncCytB) in mtDNA stability in diabetic retinopathy. Retinal endothelial cells, transfected with LncCytB-overexpressing plasmids or siRNA, incubated in 5 mmol/L d-glucose (normal glucose [NG]) or 20 mmol/L d-glucose (high glucose [HG]) for 4 days, were analyzed for LncCytB expression by strand-specific PCR and its mitochondrial localization by RNA fluorescence in situ hybridization. Damage-sensitive mtDNA regions were examined by micrococcal nuclease (MNase) digestion sequencing and LncCytB occupancy at mtDNA by chromatin isolation by RNA purification. Protective nucleoids in mtDNA were analyzed by SYBR Green-MitoTracker Red staining and confirmed in isolated mitochondria by flow cytometry. Compared with NG, HG downregulated LncCytB by >50% but had no significant effect on the other mtDNA-encoded LncRNAs. mtDNA packaging was impaired, MNase sensitivity was increased, and LncCytB occupancy at mtDNA was decreased. While LncCytB overexpression ameliorated mtDNA damage and decrease in nucleoids and copy numbers, LncCytB-siRNA exacerbated damage and further reduced nucleoids. Retinal microvessels from streptozotocin-induced diabetic mice and human donors with diabetic retinopathy presented a similar decrease in LncCytB and mtDNA nucleoids. Thus, LncCytB has a major role in maintaining mitochondrial genomic stability, and its downregulation in the hyperglycemic milieu contributes to increased vulnerability of mtDNA to damage.

Trends and Self-Management Predictors of Glycemic Control During Pregnancy in Women With Preexisting Type 1 or Type 2 Diabetes: A Cohort Study
Authors: Sushko Katelyn , Menezes Holly Tschirhart , Butt Michelle , Nerenberg Kara , Strachan Patricia , Usman Muhammad Ali , Sherifali Diana
Published: December 2022

Background

Because much of diabetes management during pregnancy occurs at home, self-management factors such as self-efficacy, self-care activities, and care satisfaction may affect glycemia. Our objective was to explore trends in glycemic control during pregnancy in women with type 1 or type 2 diabetes; assess self-efficacy, self-care, and care satisfaction; and examine these factors as predictors of glycemic control.

Methods

We conducted a cohort study from April 2014 to November 2019 at a tertiary center in Ontario, Canada. Self-efficacy, self-care, care satisfaction, and A1C were measured three times during pregnancy (T1, T2, and T3). Linear mixed-effects modeling explored trends in A1C and examined self-efficacy, self-care, and care satisfaction as predictors of A1C.

Results

We recruited 111 women (55 with type 1 diabetes and 56 with type 2 diabetes). Mean A1C significantly decreased by 1.09% (95% CI −1.38 to −0.79) from T1 to T2 and by 1.14% (95% CI −1.43 to −0.86) from T1 to T3. Self-efficacy significantly predicted glycemic control for women with type 2 diabetes and was associated with a mean change in A1C of −0.22% (95% CI −0.42 to −0.02) per unit increase in scale. The exercise subscore of self-care significantly predicted glycemic control for women with type 1 diabetes and was associated with a mean change in A1C of −0.11% (95% CI −0.22 to −0.01) per unit increase in scale.

Conclusion

Self-efficacy significantly predicted A1C during pregnancy in a cohort of women with preexisting diabetes in Ontario, Canada. Future research will continue to explore the self-management needs and challenges in women with preexisting diabetes in pregnancy.
Lytte fram forundringsøyeblikk
Authors: C. Nordli Ingrid , Skog Kristian
Published: December 2022

I denne artikkelen reflekterer vi over hvordan den lyttende pedagogen i gjensidig dialog med barn, ved hjelp av pedagogisk dokumentasjon, kan fange barns forundringsøyeblikk under tilegnelsen av trinn i lytteprosessen. Med utgangspunkt i en praksisfortelling med sang- og lytteaktiviteter, beskriver vi lyttetrinnene hos barn og reflekterer over deres forundringsresponser når de møter noe nytt. Forundringsresponsene beskrives som lyttemarkører og empirien er hentet fra én konkret lyttesituasjon. Resultatet viser at 3–6-åringer har synlige markører som kan knyttes til lyttetrinnene. Pedagogisk dokumentasjon viser at lyttemarkørene for trinnene forstå, huske og evaluere overlapper, som vanskeliggjør å avgjøre hvilket trinn de representerer. Derav presenterer vi synspunktet at lytteprosessen best lar seg beskrive sekvensvis. Formålet med artikkelen er å bidra til metodeutvikling for identifisering av skjulte trinn i barns lytteprosess. Samtidig er det et mål å framstille pedagogisk dokumentasjon som et demokratisk og hensiktsmessig redskap for å undersøke barns tilegnelse av lytteferdigheter.
ENGLISH ABSTRACT
The search for listening moments of wonder
In this article we reflect on how the listening pedagogue in reciprocal dialogue with children and on the grounds of pedagogical documentation, can capture moments of wonder in children’s acquisition of steps in the listening process. Based on a narrative of song and listening activities, we describe the listening steps and reflect on children’s responses regarding their wonder when faced with something new, in this case tonal change during singing. The responses of wonder are described through listening markers. Data is collected from one listening situation. The result shows that children at 3–6 years have visible listening markers that can be connected to listening steps. Pedagogical documentation reveals that listening markers of the steps understand, remember and evaluate, overlap, making it difficult to decide which step they represent. Hence, we regard the listening process to be best described in sequences containing a variation of steps. The purpose of this work is to contribute to the development of a method for identifying listening markers for hidden steps in children’s listening process. Simultaneously, it is a goal to portray pedagogical documentation as a democratic and suitable tool for the examination of children’s acquisition of listening skills.
Att lyssna in barns frågor - en didaktisk utmaning
Authors: Halvars Bodil , Elfström Ingela , Unga Johanna , Svedäng Mia
Published: December 2022

I föreliggande artikel belyses utifrån en studie av förskollärares gruppreflektioner inom ett nätverk hur ett förskoledidaktiskt perspektiv på undervisning växer fram inom ett avgränsat kunskapsområde. Särskilt fokuseras hur förskollärarna lyssnar in och fångar upp barns frågor och engagemang inom naturvetenskap och hållbar utveckling. Studiens empiri innehåller tolv inspelade och transkriberade fokusgruppssamtal genomförda vid tre träffar i nätverket. I samtalen framkommer hur förskollärarna utgår från barnens inspel (frågor, framväxande teorier, ageranden) som underlag för planering och genomförande av en undervisning kring naturvetenskapliga fenomen och processer samt hållbarhetsfrågor, där estetik, lek och utforskande ses som viktiga delar i relation till ämnesinnehållsliga frågor. Med utgångspunkt från begreppet lärande som ett relationellt potentialitetsfält, som formulerats i relation till Deleuzes filosofi (se Dahlberg & Elfström, 2014), framträder i analysen av samtalen även att barns och förskollärares frågor sammanfaller, går isär och att det sker parallella processer. Det framkommer också vilken betydelse förskollärarnas ämneskunskaper har för ett fortsatt utforskande när utgångspunkten är barnens frågor 
ENGLISH ABSTRACT
Listening to children’s questions - a didactic challengeThis article is based on a study of preschool teachers’ didactic group discussions within a network. It follows how a preschool didactic perspective on teaching emerges within a specific subject matter concerning natural science and sustainable development, with extra focus on how preschool teachers listen to and follow up children’s questions and engagement in the subject. The study is empirically based on twelve conversations in focus groups, from three meetings in the network, which were recorded and then transcribed. The conversations show how the preschool teachers take children’s input (questions, emerging theories, hypotheses, actions) as guidance for planning and carrying out the teaching of phenomena in natural science and processes where esthetics, play and exploration are seen as important parts in relation to subject related issues. With the concept learning as a relational field of potentiality (Dahlberg & Elfström, 2014) as a starting point, the study also sheds light on how and when the questions of children and preschool teachers overlap, diverge, when there are parallel processes, when and how preschool teachers latch on to children’s questions, and how participants knowledge of the subject matter affects the process.

Vad är det som efter många år fortfarande lockar förskollärare, pedagoger och forskare inom förskolefältet att inspireras av lyssnandets pedagogik i sina praktiker i Sverige och Norge? Vad är lyssnandets pedagogik för dem i dag, i praktiken och i teorin? Hur ska vi förstå vad som hände då och vad som händer nu i olika kontexter som kan utgöras också av två grannationer? Vad har lyssnande pedagogik betytt för förskolans framväxt och med särskilt fokus på Sverige och Norge där Ann Åbergs texter fått ett stort genomslag? Detta är frågor vi ställde oss och ville få svar på när vi efterlyste bidrag till detta specialnummer av tidskriften Nordisk Barnehageforskning på temat Lyssnandets pedagogik. Ett tjugotal forskare svarade och efter en, på grund av pandemin, utdragen och rigorös review-process publiceras nu elva artiklar i detta temanummer. Tillsammans avspeglar de en angelägen bredd i intresset för vad lyssnandets pedagogik är i dag och kan bli i framtiden.

Comparison of an Active Warm-Up vs. Passive Warm-Up on Vertical Jump Performance
Authors: Thielges Mikayla , Smith Chad
Published: December 2022

Warm-ups are an essential element of exercise and sport performance. Although research has demonstrated benefits associated with active warm-ups, research investigating the effects of a passive warm-up on subsequent performance is limited. The purpose of this study is to compare the effects of an active, post-activation potentiation (PAP) warm-up to a passive warm-up on vertical jump performance.
Study participants were randomly assigned to one of two groups. Each group performed both the active and passive warm-ups, in reverse order, to control for order effect. Participants in this study consisted of 20 college students (men and women) between the ages of 18 and 35 years who were well-trained and anaerobically fit.
A repeated measures ANOVA revealed a statistically significant main effect difference in vertical jump measures (F=16.148, p<0.001). Further analysis of the results demonstrated that between the three treatments tested, control, active, passive, there was a statically significant difference between the active warm-up when compared to both the passive and control warm-ups (p=0.004; p<0.001). The results also indicated that there was practical significance between the active and passive treatment as well as the control group (partial eta squared=0.459).
In conclusion, an active warm-up prior to vertical jump testing appears to be superior to a passive warm-up. Physiologically the body may perform better following dynamic movements rather than through a passive increase in intramuscular temperature. Prior to athletic events, we recommend athletes perform warm-ups utilizing dynamic movements rather than using a heating system alone.

Published: December 2022

The online EFL teaching and learning in this COVID-19 pandemic era has been conducted synchronously and asynchronously. However, the implementation of blended synchronous and asynchronous learning in the online grammar class was still scarce. Therefore, this study was conducted with the purpose of knowing whether or not the use of blended synchronous and asynchronous learning was effective for teaching grammar. This study was a pre-experimental research using one-group pretest-posttest design. The population of this study was the students of the second semester in the English department of a private university located in East Java. Because there was only one class in this second semester so that the sample was the same as this population. There were fifteen students in this sample. In collecting the data, the researchers used the pretest and posttest of grammar. After the data of pretest and posttest were in the normal distribution, the testing of hyphothesis using t-test especially paired samples test was conducted. The result of this t-test showed that the Sig. (2-tailed) 0.000 was lower than 0.05. It revealed that the difference of the mean scores of pretest and posttest was significant. Thus, the use of blended synchronous and asynchronous learning was effective for teaching grammar.

Tourists' demands which particularly those of international visitors are best served by tour guides, who are valuable coastal human resources. English as an international language is essential for communicating with travelers and is a crucial communication ability in the travel and tourism sector. Thence, it is necessary to analyze the English needs of local tour guides on the Simeulue coast. There were ten local tour guides chosen through random sampling as the subjects. The research instrument was a questionnaire set adapted from Prachanant (2012) address needs, functions, and issues with the use of English. It also makes reference to elements from the need analysis model developed by Waters & Hutchinson (1987).Interactive Analysis by Miles, Huberman, and Saldana (2014) was used to perform additional analysis on the findings, and the results were later displayed and verified. The results revealed that speaking was the most important English skill for the participants, followed by listening, reading, and writing. Second, individuals felt they lacked proficiency in speaking, listening, writing, and reading. Therefore, they desired to develop their speaking, listening, writing, and reading abilities. It implied that speaking played a major role in tour guiding and needs further follow-ups.

Published: December 2022

The study accentuates bilingual creativity as the pedagogical intervention of postcolonial creative writing strategy in poetry class through the writing of haiku and short poems. Twenty-five students in their freshmen year at the English Department were engaged in reading a culturally local text (Sumatra-Javanese ethnic poetry to compose poetry from a post-colonial perspective). The workshop's five phases exploring, inciting inspirations, drafting, editing, and peer feedback provided the student, as a novice writer, with the benefit of familiarizing themselves with character, theme, and cultural issues; developing a cognitive process to negotiate different meanings in their first and second languages; and exploring creativity to write their own poetry in the second language. The scripts written in English are the product of poetry classes, which reveal students' localized knowledge and cultural literacy. The works reflect the participants’ cultural identity, even though English is the dominant language showcased in the almost fifty poems composed by the novice writers. The existence of local languages points to the development of their bilingual creativity; students in the poetry classroom are not only able to handle the meaning in the first and second languages, but also to promote their local culture to the global world.

In engineering design, material selection is the process of choosing the best material for a specific process via a systematic material selection approach. This article described the material selection process for SBR#2 pipeline, which will be installed to flow raw gas from SBR#2 field to the nearest tie-in point. The material selection process starts with design requirement analysis to generate primary function and objectives, including its constraints, determine primary criteria to be evaluated, screen materials candidates based on criteria evaluation, and select the most suitable materials based on very specific requirements. The criteria were evaluated by performing value engineering with the performance criteria matrix tool. Materials selection, in this case, was determined by two main criteria: corrosion resistance and construction ability. Corrosion resistance was evaluated semi-quantitatively by applying NORSOK M-506 2005 spreadsheet, and construction ability were evaluated qualitatively based on field experience. Solid Corrosion Resistance Alloy (CRA)-Stainless Steel 316L pipe is the most suitable for this case.
Cellulose derivative as protection coating: Effect of nanoparticle additives on load capacity
Authors: Shi Shih-Chen , Tsai Xiao-Ning
Published: December 2022

The cellulose derivative hydroxypropyl methylcellulose (HPMC) has recently been extensively studied and used in mechanical applications. However, the softness and susceptibility to deformation of HPMC limited its further applications. In this study, metal nanoparticles (nano-aluminum and nano-copper) and nano-metal oxide particles (nano-alumina and nano-copper oxide) were used as additives to HPMC to form a composite film with improved mechanical properties, particularly load capacity. The addition of high levels of additives provided a higher load capacity. Among the nano-additives used in the study, Cu (2 wt.%) provided the composite with the highest load capacity, improving the load capacity of pure HPMC by 250%.   The surface treatment of strengthening additives is an important step. Adding specific high-strength and high-modulus metal and metal oxide additives to the soft HPMC matrix can effectively improve the load-bearing capacity of the composite material. This study proposes a simple evaluation method for the load-bearing capability of the coating as well.
Does Omnibus Law Affect the Indonesian Investment Regulations towards Chinese Investors?

Published: December 2022

This paper examined the polemic of Indonesian omnibus Law that affect the international market interest in Indonesia, especially for the Chinese investor. On the one hand, this act and its implementation act give hope for a more conducive climate for foreign investment. On the other hand, it also invites resistance from various components of the nation due to the non-transparent procedure of its formation. It substantively degrades the interests of the wider community and is more in favour of the interests of investors. This research comes up with the liberal institutionalism theory; when state elites do not predict self-interested benefits from cooperation, it means no expectation of cooperation to occur, nor the institutions that facilitate cooperation to develop. On the other hand, when states can jointly benefit from cooperation, governments expect to attempt to establish such an institution. . As a result, Omnibus Law affects ambiguity and uncertainty for foreign investor especially for Chinese. However Omnibus Law is still uncertain and ambiguous; in reality the foreigner investment especially Chinese Investments in Indonesia is still run well and tend to increase. It is because Constitutional Court's decision did not invalidate 47 government regulations and 4 presidential regulations derived from the Job Creation Law. In addition, from the perspective of liberal Institutionalism, it has been long time Indonesia and China has built diplomacy for continuous mutual cooperation.
