Industry 4.0-Enabled Environment, Social, and Governance Reporting: A Case from a Chinese Energy Company
Authors: Yu Wenjun , Gu Yu , Dai Jun
Published: July 2022

Accelerating climate change, deforestation, and pollution have turned a global spotlight on corporate sustainability. Many countries have issued standards on Environment, Social, and Governance (ESG) reporting, especially from heavily polluting companies. ESG disclosure has become a main channel for investors, the public, and other external stakeholders to understand companies’ impact on the environment. However, the current methods of collecting and processing environmental information are insufficient and infrequent, impairing stakeholders’ decision-making. Moreover, the complexity and diversity of environmental measures can inhibit information reliability, accuracy, and objectivity. We propose the use of Industry 4.0 technologies to improve existing ESG reporting processes and demonstrate a novel environmental reporting system that could allow a Chinese energy company to collect and report environmental information in real time, enhancing the completeness, reliability, and efficiency of their environmental disclosure.
Fabrication of frequency-selective surface by picosecond laser direct writing
Authors: Zhao Yu , Ye Yunxia , Zhang Rui , Ren Yunpeng , Ren Xudong
Published: July 2022

In this paper, a terahertz (THz) frequency-selective surface (FSS) is fabricated through picosecond (ps) laser direct writing on the silicon-based silver film. The time-domain spectroscopy (TDS) technique is used to test its electromagnetic modulation performance. Based on the finite-difference time-domain method, CST microwave studio 2016 was used to simulate its resonance characteristic. By optimizing the process parameters, the square ring structures on the FSS with the size error below 2% are fabricated. It is found that the center frequencies of the experimental and simulated resonance peaks are nearly both at 0.293 THz, and the transmission is about 0.01%. From the simulation results, when the size error is controlled below 2 μm, the resonant frequency shift is about 2.2 GHz. Combining the simulation and experimental results, if the size error of inner square is controlled below 2%, it has little effect on the THz metasurfaces’ modulation performance. By optimizing the laser scanning strategy and processing parameters, ps laser direct writing provides a new choice for the convenient fabrication of THz metamaterials.
Algoritmos, inteligência artificial e software livre na contemporaneidade
Authors: Bordignon Gabriel Barros
Published: July 2022

O artigo constrói um diálogo entre conceitos presentes na série de livros Fundação, de Isaac Asimov, e a realidade contemporânea, situada na constante presença de dispositivos tecnológicos baseados em algoritmos e inteligências artificiais (IA) nos cotidianos dos indivíduos. Coloca-se que, apesar de o enredo dos livros se passar em um longínquo e hiperbólico futuro ficcional, é possível refletir, com base em ideias como as leis da robótica e os axiomas da psico-hitória, sobre o desenvolvimento tecnológico contemporâneo, seus reflexos na produção de subjetividades, na vida social e nos processos democráticos. Argumenta-se, por fim, que diante dos vários dilemas éticos gerados pela relação entre as sociedades e as tecnologias de informação e comunicação (TIC), o software livre é um caminho possível e eficiente para que tal convivência dê-se de forma mais justa, transparente e igualitária.

Published: July 2022

Mathematical literacy is a person's ability to formulate, apply and interpret mathematics in various contexts, including the ability to reason systematically and use concepts, procedures, and facts to describe, explain or predict an event. Therefore, mathematical literacy is essential in everyday life. This article analyzed the mathematical literacy of junior high school students in Bandar Lampung. Data were collected by giving mathematical literacy questions to junior high school students. The data were analyzed descriptive–quantitatively. The research population is 14–15 years junior high school students in Bandar Lampung City. The research sample was selected using a stratified sampling technique to get students from several favorable and unfavorable public and private junior high schools. The research instrument was a test on the mathematical literacy of junior high school students. The results showed that junior high school students in Bandar Lampung were generally able to solve mathematical literacy problems whose information was clearly available, solve problems procedurally, and use basic algorithms, formulas, procedures, or conventions involving integers. However, they have yet to solve problems that involve constraints or make assumptions. They have not been able to select and integrate different representations, including symbolic ones, relate them directly to aspects of real–world situations and have not been able to solve problems related to everyday life that they rarely encounter.

Authors: Kholid Muhammad Noor , Ahadiyati Arina
Published: July 2022

Students’ metacognition abilities based on their aspects have different levels. Metacognition aspects had categorized into parts of awareness aspects, evaluation aspects, and aspects of regulation. This study aims to describe how students are metacognitive in solving non-routine problems based on awareness, evaluation, and regulation characteristics. This research is a descriptive qualitative study with a sampled class VIII A Junior High School Batik Special Program (PK) Surakarta, which consisted of six students. The instruments in this research are non-routine problems or tests, observation sheets, and interview guidelines. The questions validator in this research are two teachers and a Mathematics Education lecturer from the University of Muhammadiyah Surakarta. The data collection technique uses tests, observations, and interviews. The data analysis technique of research had carried out through three stages: data reduction, data presentation, and conclusion drawing. This study concluded that the student's metacognition of eighth grade in solving non-routine problems had not developed better. Only one student can ideally find the metacognition aspects of awareness, evaluation, and regulation. Compared to medium-capable students, students with high abilities can discover the metacognition aspects well. In comparison, students with low skills have not been able to find all indicators of metacognition. Based on the results, further research may discover students’ obstacles in implementing metacognition for mathematical problem-solving.

Published: July 2022

Perjalanan sejarah penulisan hadis masih menjadi perdebatan di kalangan orientalis (Barat) maupun sarjana muslim (Timur) tentang awal penulisannya. Mustafa Azami merupakan tokoh muslim ahli hadis yang meyakini bahwa penulisan hadis sudah dimulai sejak Rasulullah masih hidup. Penelitian kepustakaan dengan pendekatan kualitatif ini menggunakan data utama yang berasal dari karya Mustafa Azami berjudul “Studies in Early Hadith Literature” (Hadis Nabawi dan Sejarah Kodifikasinya) dan data pendukung dari artikel jurnal, buku, dan berita online yang berkaitan dengan tema artikel ini. Analisis konten dalam artikel ini dilakukan untuk menjelaskan bagaimana Mustafa Azami secara objektif menilai sejarah penulisan hadis. Hasil penelitian menunjukkan bahwa pemikiran Mustafa Azami tentang sejarah penulisan hadis memiliki objektivitas yang tinggi. Mustafa Azami memaparkan fakta-fakta penulisan hadis yang dimulai sejak masa Rasulullah SAW dan berkelanjutan tanpa putus sampai akhir abad kedua dan dimulainya kodifikasi hadis. Kesimpulan Azami tersebut telah menggugurkan argumen bahwa hadis baru mulai ditulis pada pertengahan abad kedua sekaligus meruntuhkan tuduhan para orientalis bahwa hadis tidak autentik.

Kajian ini bertujuan untuk menganalisa bagaimana implikasi prosedur pencatatan perkawinan pada masa pemberlakuan pembatasan kegiatan masyarakat (PPKM) dalam perspektif fiqih Nusantara. Penelitian ini tergolong dalam penelitian studi pustaka dan menggunakan analisis konten, disamping itu juga peneliti melakukan penggalian data dengan observasi dan wawancara kepada pihak yang terkait secara langsung dengan tema penelitian ini. Hasil penelitian menunjukkan bahwa implikasi prosedur pencatatan perkawinan  pada masa PPKM yakni adanya penundaan perkawinan dan perkawinan siri. tindakan ini jika ditinjau dalam perspektif fiqih Nusantara, berbeda dengan tindakan penundaan perkawinan, sebaliknya perkawinan siri tidak bisa dibenarkan. Karena secara esensi fiqih Nusantara mengimplementasikan maqashid syari’ah berupa pencegahan kemudharatan dan perwujudan kemaslahataan. Penundaan perkawinan dipandang sebagai bentuk penerapan maqashid syari’ah, sedangkan Perkawinan siri selain sebagai bentuk ketidakpatuhan kepada peraturan pemerintah, tindakan ini juga akan berpotensi menimbulkan masalah terkait pemenuhan hak dan kewajiban bagi rumah tangga dikemudian hari.
The Problem of Religious Freedom In the Practice of Amar Ma'ruf Nahi Munkar
Authors: Latief Mohamad , Rizqon Ahmad , Kusuma Amir Reza , Kubro Syaikhul
Published: July 2022

The issue of religious freedom continues to grow. A number of figures and institutions are constantly campaigning for religious freedom to every level of society. This effort emerged after the right of religious freedom seems to have been misinterpreted by attitudes that were considered intolerant and did not respect differences. This writing is quite interesting to study, due to the strong assumption that everyone has the freedom to embrace religion and worship according to his religion, and everyone is free to believe in beliefs, express thoughts and attitudes, according to his conscience. This study is a literature review, the method used is descriptive method, and conclusions are drawn by using deductive thinking. The result of this study is that religion gives freedom to anyone to choose between religion or even being an atheist. The practice of amar ma'ruf nahi munkar is a religious order and does not violate religious freedom. Islam does not force someone to embrace a certain religion, but Islam obliges every Muslim to convey goodness, invites to the truth, and avoids disgraceful actions, such as Habib Abdullah's theory which says that the great symbol of religion is amar ma'ruf nahi munkar.

Published: July 2022

Problem solving is one of the most important skills for students. Meanwhile, logical thinking is the ability to solve problems by relying on mental abilities. The purpose of this research is to describe the problem solving process of students with different levels of logical thinking. This research is an exploratory qualitative research involving eighth grade students of SMP N 5 Tuban who have different levels of logical thinking as research subjects. The subjects who were interviewed were 4 students. Instruments to measure the level of logical thinking used The Group Assessment of Logical Thinking (GALT) while exploring the process of solving problems using the stages of entry, attack, and review. The results of the analysis show that students with high logical thinking skills meet the entry, attack, and review stage. Students with low logical thinking skills meet the entry stage in ‘know’ and ‘want’ aspects only, at the attack stage they only meet the try and possible aspects, and do not meet the review stage at all. Thus, it can be concluded that students with different levels of logical thinking ability have different mathematical problem solving abilities.

Published: July 2022

This study aims to compile and develop an international didactic situtation presented with an approach to the center of an arbitrary triangle in visual exploration in 2D and 3D format using GeoGebra software as a technology for modification and construction of Olympiad questions. The methodology used in this study is an exploratory qualitative which is described from a didactic sequence of Mathematics Olympiad which were held in four online meetings using Google Meet. The results show that this exercise can be used as a resource that will provide a level of learning for students through command and visualization of images that serve a broad view of the international Olympiad situation. International didactic situations can be applied by mathematics teachers both in training for national and international Olympiad and for classroom teaching. In summary, it is noteworthy that the dynamic records of semiotic representations stimulated by the use of GeoGebra software has great potential to encourage the progress of students’ representative geometric thinking, through the development of visualization, perception, and mathematical intuition. It is hoped that this work can serve as a pedagogical and methodological tool by teachers for various competencies.

Published: July 2022

Objectives: Real-time polymerase chain reaction is currently used as a confirmatory test for coronavirus disease 2019 (COVID-19). The test results are interpreted as positive, negative, or inconclusive, and are used only for a qualitative classification of patients. However, the test results can be quantitated using threshold count (Ct) values to determine the amount of virus present in the sample. Therefore, this study investigated the diagnostic usefulness of Ct results through various quantitative analyzes, along with an analysis of clinical and epidemiological characteristics.Methods: Clinical and epidemiological data from 4,642 COVID-19 patients in April 2021 were analyzed, including the Ct values of the RNA-dependent RNA polymerase (RdRp), envelope (E), and nucleocapsid (N) genes. Clinical and epidemiological data (sex, age, underlying diseases, and early symptoms) were collected through a structured questionnaire. A correlation analysis was used to examine the relationships between variables.Results: All 3 genes showed statistically significant relationships with symptoms and severity levels. The Ct values of the RdRp gene decreased as the severity of the patients increased. Moreover, statistical significance was observed for the presence of underlying diseases and dyspnea.Conclusion: Ct values were found to be related to patients’ clinical and epidemiological characteristics. In particular, since these factors are closely related to symptoms and severity, Ct values can be used as primary data for predicting patients’ disease prognosis despite the limitations of this method. Conducting follow-up studies to validate this approach might enable using the data from this study to establish policies for preventing COVID-19 infection and spread.

¿Cómo comprender la solución de Meillassoux al dilema espectral?
Authors: Rojas Nicolás
Published: July 2022

El presente artículo se enmarca en el contexto de la alternativa ofrecida por Quentin Meillassoux a la cuestión de la pregunta canónica —¿por qué hay algo y no más bien nada? (2018f)— y pretende reflexionar sobre las condiciones que posibilitan la solución del dilema espectral (2016b) en el marco de una ontología extra científica (2020). Concebir el advenimiento de una entidad divina implicaría comprender, al menos, tres conceptos claves para el pensamiento del filósofo, a saber, el correlacionismo, factualidad y contingencia absoluta. De esta manera, el objetivo principal de este artículo es esbozar una lectura introductoria a los cimientos de la filosofía de Meillassoux a fin de comprenderla como una ontología capaz de dar cuenta de la inexistencia divina.

Purpose: This study aims to analyze how transformative learning (TL) theory has contributed to sustainability practices in management and Education for Sustainable Development (ESD) and what kind of strategies can direct future practices in the field.
 
Method/design/approach: An exploratory and inductive study to synthetize primary qualitative case studies was conducted. After screening 241 articles extracted from the Web of Science database, we identified 13 empirical papers highlighting TL theory and sustainability. Then, a meta-synthesis of these qualitative case studies was conducted based on the key characteristics of TL.
 
Results and conclusion: Six theoretical propositions were elaborated, showing that the TL theory has contributed to sustainability through some influential factors on process, conditions, and results. In addition, based on these dimensions, the study provides some strategies for future practices.
 
Research implications: The findings of this study have both theoretical and practical contributions, which can direct organizational and educational politics and practices.
 
Originality/value: Sustainability and ESD are current topics in the academy in favor of the Sustainable Development Goals (SDGs). However, there is a lack of studies on the development of theoretical strategies towards sustainability practices in management and ESD from a transformative learning TL approach. Thus, this study shed more light on the topic.

Tissue engineering is one of the pillars of regeneration techniques in medicine, based on the use of mesenchymal stem cells (MSCs). MSCs have self-renewal and differentiation capabilities in multiple lines, due to which they are multipotent mature cells. MSCs can be spread over several tiles, a good amount of MSCs is in the oral cavity, including parts such as the alveolar bone, periodontal ligament, dental pulp, dental follicle, oral mucosa and gums. Despite being a major advance in medical sciences, the use of MSCs may be limited by several factors that affect the biological capabilities of these cells. Considering the oral cavity as one of the main sources of obtaining a high amount MSCs, one of the factors that has great repercussions on oral health and diabetes, the clearest example is the two-way relationship that has periodontitis today. periodontitis is considered the sixth complication of diabetes. Given the above, it is necessary to identify the effects thatcould also have on the MSCs obtained in the oral cavity, effects that could hinder their use in tissue engineering. The purpose of this review is to describe the effect of diabetes on MSCs in the oral cavity.

Using the trust management mechanism as a way to prevent conflicts of interest in the public service: the US experience
Authors: Gorokhova Svetlana Sergeevna
Published: July 2022

The subject of the study is the legislative and law enforcement experience of the United States in the field of using special types of trust management of property of civil servants and officials as a tool to overcome conflicts of interest in the public service. The relevance of this study is confirmed by the fact that the United States, one of the few states that uses this tool, as well as the Russian Federation. However, in our country, the legal regulation of this institution is still not perfect enough, therefore, it is important enough to study the experience of those states where there is such a practice. The work was prepared as part of the state assignment to the Financial University under the Government of the Russian Federation for 2022. The scientific novelty of the research is determined by the fact that currently there are practically no works containing an analysis of the institute in question. In the course of the study, the following conclusions were made.The most developed, from the point of view of the legal regulation of the institution of trust management of the property of civil servants, is the legal regulation in the USA, where, in addition to the legislative consolidation of the very possibility of placing their assets in a trust (as an alternative to sale), there are detailed administrative regulations for the actions of employees, including, among other things, developed forms forms of documents for each stage of the procedure. For Russian legislation, a detailed regulation of the actions of civil servants in the situation with the transfer of property to trust management also seems very reasonable, since the current reference to the norms of civil legislation obviously does not satisfy the necessary regulatory need, which leads to significant difficulties in law enforcement.
Transient, Multiscale, Heterogeneous Model of Hydrogen Peroxide Decomposition for 3D-Printed Catalysts
Authors: Reid Simon , Symons Digby , Watson Matthew
Published: July 2022

Hydrogen peroxide thrusters rely on catalysts to generate steam and oxygen, and yet relatively little is known about the processes that occur within the catalyst bed. Previous models have assumed that both diffusional resistances and temperature differences between the catalyst and the fluid can be ignored. In this paper a 1D, multiscale, transient, heterogeneous, and diffusion-enabled model of catalytic hydrogen peroxide decomposition was developed and applied to a 3D-printed catalyst bed, which offers potentially significant benefits over conventional silver mesh catalysts. A triply periodic minimal surface was the chosen geometry. Simulation results suggest that the heterogeneous and diffusion-limited nature of the reaction cannot be ignored if accurate predictions about the catalyst bed performance are to be made. Through the newfound capabilities of the present model, the influence of various parameters, such as the hydrogen peroxide concentration, pressure, geometric unit cell size, bed void fraction, and support material, were characterized. Increasing the concentration, decreasing the unit cell size, and increasing the void fraction are all effective strategies for improving the performance of hydrogen peroxide thrusters, made possible by new catalytic materials and the advent of 3D-printing.
Aero-Propulsive Modeling for Propeller Aircraft Using Flight Data
Authors: Simmons Benjamin M. , Gresham James L. , Woolsey Craig A.
Published: July 2022

This paper describes methods to identify an integrated propulsion–airframe aerodynamic model and a decoupled propulsion model for fixed-wing aircraft with propellers using flight data. Propulsion aerodynamics and airframe aerodynamics for propeller aircraft are usually modeled separately, which fails to describe unavoidable interaction effects and propeller performance deviations when integrated on an aircraft. Two novel flight test system identification approaches are presented to develop flight dynamics models with improved characterization of propeller aerodynamics compared to conventional methods. Orthogonal phase-optimized multisine inputs are applied to both the control surfaces and propulsion system to generate data with high-quality information content for model identification. Propulsion explanatory variables derived from propeller aerodynamics theory combined with traditional aircraft modeling variables yield accurate aero-propulsive modeling results and provide propeller performance estimates, which are compared to isolated propeller wind tunnel data. An assessment of model adequacy using flight maneuvers withheld from model identification indicates that the models have good prediction capability. The paper describes application of these methods to a small unmanned aircraft, but the methods are generalizable to many propeller-driven aircraft.

ABSTRACT – This research includes an analysis of the media frameworks built around the Catalan government’s attempt to organize the referendum for independence from Spain on Oct 1st, 2017. Based on previous studies on the use of pragmatic and symbolic frameworks during independence processes, the objective is to identify the main interpretive frameworks, actors, and actions that starred in the symbolic battle over national identities, comparing (1) the media coverage of the referendum in two national, two international, and two regional newspapers with (2) the social debate on Twitter. The comparative quantitative analysis shows how the media prioritized emotional information and historical aspects, with notable differences between the national media and the social debate on Twitter. The coverage in international newspapers, however, was more similar to the debate on Twitter and had a notable influence on framing this public issue.

Background:

Flow diverter (FD) placement is generally effective for intractable internal carotid artery (ICA) aneurysms. However, salvage treatment for the aneurysm enlarging even after FD placement remains to be elucidated. Additional overlapping FD placement is considered the first-line treatment for residual or recurrent aneurysms. However, it is unclear whether overlapping FD is also effective for enlarging giant aneurysms that are considered impending rupture status. Although parent artery occlusion is a promising option, treatment strategy must be optimized, especially when a critical perforating artery is involved.

Case Description:

A 74-year-old woman experienced rapid symptomatic growth of her giant supraclinoid ICA aneurysm 10 months after FD placement. We assumed that reinforcement of flow diverting effect alone would be less effective for this extremely intractable aneurysm with more aggressive clinical feature so that surgical bailout by parent artery occlusion was planned. Complete ICA obliteration underneath the aneurysm was unavailable due to the presence of anterior choroidal artery. Thus, we took a flow alteration strategy, where we created minimal retrograde flow through the parent artery by a combination of an extracranial-intracranial bypass and targeted endovascular proximal parent artery obliteration, resulting in prevention of aneurysmal rupture and further growth.

Conclusion:

Impending rupture of the intracranial giant aneurysm after FD placement may be controllable with a tailor-made parent artery occlusion strategy even when a critical perforating artery is involved.

Проблема лесных пожаров становится все более заметной как в глобальном, так и в местном масштабе. Пожары в Якутии являются серьезной проблемой. Бореальные леса играют важную роль в глобальном потеплении и циркуляции углекислого газа. Изменения пожарного режима и климата в этом регионе уже начались, и это оказывает влияние на углеродную динамику в региональном и глобальном масштабе. Все чаще при изучении пожаров используются спутниковые данные. В последние годы при обработке спутниковых данных используются так называемые "большие данные". Чтобы правильно оценить масштаб угрозы, необходимо разработать эффективную методику оценки послепожарных характеристик. Для исследований были выбраны данные с сенсора MODIS Collection 6 из-за их большей доступности и достаточного пространственного разрешения для нашей работы. Использованы данные за период с 2001 по 2019 год из пожарного архива FIRMS. В данной статье представлен метод определения некоторых характеристик пожаров с использованием "больших данных" и платформы Google Earth Engine. Алгоритмы, созданные для определения основных послепожарных характеристик, были применены на примере Верхоянского района Якутии. Результаты приведены на примере пожаров в период 2001-2019 годов. Для анализа использовались данные программы FIRMS из инструмента Modis и VIIRIS, а также данные Landsat.

Molecular catalysts for ammonia oxidation to dinitrogen represent enabling components to utilize ammonia as a fuel and/or source of hydrogen. Ammonia oxidation requires not only the breaking of multiple strong N-H bonds, but also controlled N-N bond formation. We report a novel β-diketiminato copper complex [iPr2NNF6]Cu-NH3 ([Cu(I)]-NH3 (2)) as a robust electrocatalyst for NH3 oxidation in acetonitrile under homogeneous conditions. Complex 2 operates at a moderate overpotential (700 mV) with a TOFmax = 940 h-1 as determined from CV data in 1.3 M NH3 MeCN solvent. Prolonged (>5 h) controlled potential electrolysis (CPE) reveals the stability and robustness of the catalyst under electrocatalytic conditions. Detailed mechanistic investigations indicate that electrochemical oxidation of [Cu(I)]-NH3 forms {[Cu(II)]-NH3}+ (4) which undergoes deprotonation by excess NH3 to form reactive copper(II)-amide [Cu(II)]-NH2 (6) unstable towards N-N bond formation to give the dinuclear hydrazine complex [Cu(I)]2(mu-N2H4). Electrochemical studies reveal that the bisammine complex [Cu(I)](NH3)2 (7) forms at high ammonia concentration as part of the {[Cu(II)](NH3)2}+/[Cu(I)](NH3)2 redox couple that is electrocatalytically inactive. DFT analysis reveals a much higher thermodynamic barrier for deprotonation of {[Cu(II)](NH3)2}+ (8) by NH3 to give the four-coordinate copper(II) amide [Cu(II)](NH2)(NH3) (9) (dG = 31.7 kcal/mol) as compared to deprotonation of the three coordinate {[Cu(II)]-NH3}+ by NH3 to provide the reactive three coordinate parent amide [Cu(II)]-NH2 (dG = 18.1 kcal/mol) susceptible to N-N coupling to form [Cu(I)]2(mu-N2H4) (dG = -11.8 kcal/mol).
