Silencing of the Ortholog of DEFECTIVE IN ANTHER DEHISCENCE 1 Gene in the Woody Perennial Jatropha curcas Alters Flower and Fruit Development
Authors: Xu Chuan-Jia , Zhao Mei-Li , Chen Mao-Sheng , Xu Zeng-Fu
Published: November 2020

DEFECTIVE IN ANTHER DEHISCENCE 1 (DAD1), a phospholipase A1, utilizes galactolipids (18:3) to generate α-linolenic acid (ALA) in the initial step of jasmonic acid (JA) biosynthesis in Arabidopsis thaliana. In this study, we isolated the JcDAD1 gene, an ortholog of Arabidopsis DAD1 in Jatropha curcas, and found that it is mainly expressed in the stems, roots, and male flowers of Jatropha. JcDAD1-RNAi transgenic plants with low endogenous jasmonate levels in inflorescences exhibited more and larger flowers, as well as a few abortive female flowers, although anther and pollen development were normal. In addition, fruit number was increased and the seed size, weight, and oil contents were reduced in the transgenic Jatropha plants. These results indicate that JcDAD1 regulates the development of flowers and fruits through the JA biosynthesis pathway, but does not alter androecium development in Jatropha. These findings strengthen our understanding of the roles of JA and DAD1 in the regulation of floral development in woody perennial plants.
Sulfur Homeostasis in Plants
Authors: Li Qian , Gao Yan , Yang An
Published: November 2020

Sulfur (S) is an essential macronutrient for plant growth and development. S is majorly absorbed as sulfate from soil, and is then translocated to plastids in leaves, where it is assimilated into organic products. Cysteine (Cys) is the first organic product generated from S, and it is used as a precursor to synthesize many S-containing metabolites with important biological functions, such as glutathione (GSH) and methionine (Met). The reduction of sulfate takes place in a two-step reaction involving a variety of enzymes. Sulfate transporters (SULTRs) are responsible for the absorption of SO42− from the soil and the transport of SO42− in plants. There are 12–16 members in the S transporter family, which is divided into five categories based on coding sequence homology and biochemical functions. When exposed to S deficiency, plants will alter a series of morphological and physiological processes. Adaptive strategies, including cis-acting elements, transcription factors, non-coding microRNAs, and phytohormones, have evolved in plants to respond to S deficiency. In addition, there is crosstalk between S and other nutrients in plants. In this review, we summarize the recent progress in understanding the mechanisms underlying S homeostasis in plants.

Published: November 2020

Myocardial interstitial fibrosis (MIF) is characterized by excessive extracellular matrix (ECM) deposition, increased myocardial stiffness, functional weakening, and compensatory cardiomyocyte (CM) hypertrophy. Fibroblasts (Fbs) are considered the principal source of ECM, but the contribution of perivascular cells, including pericytes (PCs), has gained attention, since MIF develops primarily around small vessels. The pathogenesis of MIF is difficult to study in humans because of the pleiotropy of mutually influencing pathomechanisms, unpredictable side effects, and the lack of available patient samples. Human pluripotent stem cells (hPSCs) offer the unique opportunity for the de novo formation of bioartificial cardiac tissue (BCT) using a variety of different cardiovascular cell types to model aspects of MIF pathogenesis in vitro. Here, we have optimized a protocol for the derivation of hPSC-derived PC-like cells (iPSC-PCs) and present a BCT in vitro model of MIF that shows their central influence on interstitial collagen deposition and myocardial tissue stiffening. This model was used to study the interplay of different cell types—i.e., hPSC-derived CMs, endothelial cells (ECs), and iPSC-PCs or primary Fbs, respectively. While iPSC-PCs improved the sarcomere structure and supported vascularization in a PC-like fashion, the functional and histological parameters of BCTs revealed EC- and PC-mediated effects on fibrosis-related cardiac tissue remodeling.
Transcriptional Regulation of Dental Epithelial Cell Fate
Authors: Yoshizaki Keigo , Fukumoto Satoshi , Bikle Daniel D. , Oda Yuko
Published: November 2020

Dental enamel is hardest tissue in the body and is produced by dental epithelial cells residing in the tooth. Their cell fates are tightly controlled by transcriptional programs that are facilitated by fate determining transcription factors and chromatin regulators. Understanding the transcriptional program controlling dental cell fate is critical for our efforts to build and repair teeth. In this review, we describe the current understanding of these regulators essential for regeneration of dental epithelial stem cells and progeny, which are identified through transgenic mouse models. We first describe the development and morphogenesis of mouse dental epithelium in which different subpopulations of epithelia such as ameloblasts contribute to enamel formation. Then, we describe the function of critical factors in stem cells or progeny to drive enamel lineages. We also show that gene mutations of these factors are associated with dental anomalies in craniofacial diseases in humans. We also describe the function of the master regulators to govern dental lineages, in which the genetic removal of each factor switches dental cell fate to that generating hair. The distinct and related mechanisms responsible for the lineage plasticity are discussed. This knowledge will lead us to develop a potential tool for bioengineering new teeth.
Comparison of Different Parameters to Evaluate Delamination in Edge Trimming of Basalt Fiber Reinforced Plastics (BFRP)
Authors: Navarro-Mas María Dolores , Meseguer María Desamparados , Lluch-Cerezo Joaquín , García-Manrique Juan Antonio
Published: November 2020

Delamination is one of the main problems that occur when machining fiber-reinforced composite materials. In this work, Types I and II of delamination are studied separately in edge trimming of basalt fiber reinforced plastic (BFRP). For this purpose, one-dimensional and area delamination parameters are defined. One-dimensional parameters (Wa and Wb) allow to know average fibers length while the analysis of area delamination parameters (Sd) allow to evaluate delamination density. To study delamination, different tests are carried out modifying cutting parameters (cutting speed, feed per tooth and depth of cut) and material characteristics (fiber volume fraction and fiber orientation). Laminates with a lower fiber volume fraction do not present delamination. Attending to one-dimensional parameters it can be concluded that Type II delamination is more important than Type I and that a high depth of cut generates higher values of delamination parameters. An analysis of variance (ANOVA) is performed to study area parameters. Although delamination has a random nature, for each depth of cut, more influence variables in area delamination are firstly, feed per tooth and secondly, cutting speed.
A Novel Testing Method for Examining Corrosion Behavior of Reinforcing Steel in Simulated Concrete Pore Solutions
Authors: Li Yanru , Liu Jiazhao , Dong Zhijun , Xing Shaobang , Lv Yajun , Li Dawang
Published: November 2020

In this paper, a new mechanical-based experimental method is proposed to determine the corrosion initiation and subsequent corrosion behavior of steel in simulated concrete pore solutions. The proposed experiment is used to investigate the corrosion of the steel wire under various different conditions and to examine the effects of pre-stress level in steel wire, passivation time of steel wire, composition and concentration of simulated concrete pore solution on the corrosion initiation, and subsequent corrosion development in the steel wire. The experimental results show that the reduction rate of the cross-section area of the steel wire increases with the increase of chloride concentration or decrease of pH value in the solution. However, for the case where the chloride concentration is high and the pH value is low, there is a slight decrease in the corrosion rate due to the coating function of the corrosion products surrounding the wire.
The Influence of Curing Systems on the Cure Characteristics and Physical Properties of Styrene–Butadiene Elastomer
Authors: Maciejewska Magdalena , Siwek Monika
Published: November 2020

The goal of this work is to study the influence of different curing systems on the cure characteristics and performance of styrene–butadiene elastomer (SBR) filled with carbon black or nanosized silica. A multifunctional additive for rubber compounds, namely Activ8, was applied as an additional activator and accelerator to increase the efficiency of sulfur vulcanization and to reduce the content of zinc oxide elastomers cured in the presence of 2-mercaptobenzothizole or 1,3-diphenylguanidine as a primary accelerator. The influence of the curing system composition on the crosslink density and physical properties of SBR vulcanizates, such as mechanical properties, thermal stability, and resistance to thermo-oxidative aging, is also reported. Activ8 effectively supports the vulcanization of SBR compounds, especially filled with nanosized silica. It reduces the optimal vulcanization time of SBR compounds and increases the crosslink density of the vulcanizates. Moreover, vulcanizates with Activ8 exhibit higher tensile strength and better damping properties than elastomer with zinc oxide. Activ8 allows the amount of ZnO to be reduced by 40% without detrimental effects on the crosslink density and mechanical performance compared to the vulcanizates conventionally crosslinked with ZnO. This is an important ecological goal since ZnO is classified as being toxic to aquatic species.
Reducing Response Time in Motor Imagery Using A Headband and Deep Learning
Authors: Garcia-Moreno Francisco M. , Bermudez-Edo Maria , Garrido José Luis , Rodríguez-Fórtiz María José
Published: November 2020

Electroencephalography (EEG) signals to detect motor imagery have been used to help patients with low mobility. However, the regular brain computer interfaces (BCI) capturing the EEG signals usually require intrusive devices and cables linked to machines. Recently, some commercial low-intrusive BCI headbands have appeared, but with less electrodes than the regular BCIs. Some works have proved the ability of the headbands to detect basic motor imagery. However, all of these works have focused on the accuracy of the detection, using session sizes larger than 10 s, in order to improve the accuracy. These session sizes prevent actuators using the headbands to interact with the user within an adequate response time. In this work, we explore the reduction of time-response in a low-intrusive device with only 4 electrodes using deep learning to detect right/left hand motion imagery. The obtained model is able to lower the detection time while maintaining an acceptable accuracy in the detection. Our findings report an accuracy above 83.8% for response time of 2 s overcoming the related works with both low- and high-intrusive devices. Hence, our low-intrusive and low-cost solution could be used in an interactive system with a reduced response time of 2 s.

Bismuth ferrite nanoparticles with an average particle diameter of 45 nm and spatial symmetry R3c were obtained by combustion of organic nitrate precursors. BiFeO3-silicone nanocomposites with various concentrations of nanoparticles were obtained by mixing with a solution of M10 silicone. Models of piezoelectric generators were made by applying nanocomposites on a glass substrate and using aluminum foil as contacts. The thickness of the layers was about 230 μm. There was a proportional relationship between the different concentrations of nanoparticles and the detected potential. The output voltages were 0.028, 0.055, and 0.17 V with mass loads of 10, 30, and 50 mass%, respectively.

Висвітлено питання, пов’язані з практичними причинами, які впливають на рівень абсентеїзму. Розглядається сутність абсентеїзму, ілюструються форми його проявів, аналізуються причини політичного абсентеїзму як явища. Природа абсентеїзму розкривається в статті багатоаспектно: і як політична позиція індивіда (аспект індивідуального вибору), і як суспільний феномен (показник рівня залученості в політику груп населення), і як неминучий елемент виборчого процесу (причини, що перешкоджають волевиявленню громадян).
ПРОБЛЕМИ ТРАНСФОРМАЦІЇ ПОЛІТИЧНОЇ СУБ’ЄКТНОСТІ В ПОСТІНДУСТРІАЛЬНОМУ СУСПІЛЬСТВІ
Authors: Воронянський О. В.
Published: November 2020

Перехід економічної системи на постіндустріальний рівень кардинально змінив соціальну структуру суспільства. Організований робітничий клас і його масові партії, чия ідеологія базувалася на усвідомленні системної класової спільності в процесі виробництва, поступилися місцем не пов’язаним із цим процесом дрібним спільнотам, які об’єднуються на основі культурних кодів споживання. Відповідно, перехід від класової суб’єктності індустріального суспільства до фрагментованої декласованої суб’єктності постіндустріалізму для більшості населення означає відмову від боротьби за реальні інтереси на користь сформованих політичною елітою симулякрів цих інтересів. Дії таких суб’єктів у межах нав’язаних їм кодів культури споживання не призводить до зміни реального політичного порядку, не дозволяють, а лише тимчасово компенсують зростаючі структурні політичні конфлікти.

У період постіндустріального суспільства вичерпання можливостей ринкового розподілу ресурсів створює тенденцію переходу від реальної економічної діяльності до ренто-орієнтованої поведінки. Однак така форма задоволення соціальних запитів створює загрозливу тенденцію до самознищення самої інфраструктури сучасного суспільства і подальшої фрагментацією простору політичної суб’єктності.

Повернення реальної політичної суб’єктності більшості може бути пов’язано з трансформацією розрізнених груп у новий політичний клас. Ці цілі мають на увазі легітимізацію нового політичного порядку, в якому ієрархія доступів до ресурсів суспільства перестає бути ключовим фактором соціальної стратифікації.

Published: November 2020

Interaction of 1,1-diamino-2,2-dinitroethylene with nAl+mGa (n,m:1,2) admixture has been investigated within the constraints of density functional theory at the level of UB3LYP/6-311++G(d,p). Various multiplicity states arise for the composites due to the open-shell ground state electronic configurations of Al and Ga atoms. The composites are electronically stable, thermodynamically exothermic and have favorable Gibbs’ free energy of formation values. Various quantum chemical properties have been obtained and discussed. The calculated UV-VIS spectra indicate that some of the composites are infrared absorbing systems beyond 700 nm.

Teaching ethics to accounting students is a challenge for lecturers. Lack of knowledge on how to teach ethics and limited references to ethics teaching materials are examples of obstacles to teaching ethics. The film has been an exciting learning resource in accounting courses, which is a fun way to learn and full of value. This study is a preexperimental study to determine the effectiveness of using film media to convey ethical material to students majoring in Accounting, Politeknik Negeri Malang. The method used in this study is descriptive qualitative. Based on the results of this experiment, 32 students stated that there were moral values that were learned from watching films. In contrast, 17 people indicated that they had learned other things such as cases of economic crisis and the application of the material in class to real life. Based on these results, films could be used as an alternative to teaching ethics to accounting students. This study offered a reference for accounting lecturers the ways to use film in accounting classes and samples of discussion and assignments in using film as a teaching resource. The result of this study could be a reference in renewing the curriculum to insert film as a learning resource, also to consider other learning resources.

Published: November 2020

Objective: we aimed to assess the efficacy and safety of pulmonary vein (PV) cryoballoon ablation (CBA) in patients with a common trunk of the pulmonary veins (PVCT).

Materials and methods: We performed a retrospective analysis of 596 primary PV CBA procedures using the second-generation cryoballoon (CB) Arctic Front Advance (28 mm). PV anatomy was visualized using direct LA angiography during high-frequency right ventricular pacing. We included forty-nine patients in whom a PVCT was identified. The one-step and sequential ablation approaches with simultaneous recording of biophysical and electrophysiological parameters were used for PVCT isolation. During CBA in the right PVs, high-output (2000 ms, 25 mA) pacing of the right phrenic nerve was performed via a electrode placed in the superior vena cava, and amplitude of diaphragm movement was monitored. In the case of impairment/loss of the diaphragm contraction ablation was immediately stopped.

Results: 91.1% (543) patients had the normal drainage of PV. In 4 patients (0.67%), an additional right pulmonary vein was identified. The prevalence of PVCT was 8.2% (49 pts): a left common trunk (LCT) was observed in 43 patients (87.7%), a right common trunk (RCT) - in 6 patients (12.2%). Acute efficacy of PVCT isolation was 95.9% (47/79): in LCT - 95.3%, in RCT - 100%. The feasibility of the one-step antral isolation was 59.1% (n=29). During a median follow up of 12 (3-20) months, the clinical success rate of the procedure was 69.4%. A comparative analysis showed no significant difference between common trunk ablation approaches and clinical efficacy (p=0.346).

Conclusion: CBA has been shown effective and safe for symptomatic AF patients with PVCT. The simultaneous and sequential ablation approaches can be performed with comparable efficacy.

Introduction. Radiofrequency ablation (RFA) is an established treatment of post-myocardial infarction ventricular tachycardia (VT). Endocardial VT ablation can be insufficient for VT termination when the scar is intramural/epicardial.

Purpose: to assess the extent of epicardial electrophysiological VT substrate in patients with remote myocardial infarction.

Materials and methods. Thirteen patients with sustained postinfarction VT, who signed an informed consent, were included into the study. All patients underwent full clinical evaluation. Electroanatomical voltage bi- and unipolar mapping of endocardial and epicardial surfaces was performed. Maps were evaluated for the presence of low-voltage areas and local abnormal ventricular activity (LAVA). RFA was performed at LAVA sites. The end-point of the procedure was scar LAVA abolition and VT noninducibility (procedure success). VT recurrence was detected using an implantable cardioverter-defibrillator and/or ECG monitoring.

Results. Epicardial access was successful in 12 patients. Epicardial access was performed at a first procedure in 7 patients, 4 patients had a history of previous endocardial ablation. Epicardial LAVA sites were detected in 9 patients. Endocardial and epicardial arrhythmogenic substrate localization coincided in 8 patients. One patient had only epicardial scar, 1 patient had only septal endocardial scar. In one patient LAVA sites had different localizations on epicardial and endocardial maps. Acute ablation success was noted in 12 patients.

Conclusion. In our patient group transmural scar and epicardial electrophysiological arrhythmogenic substrate was detected in 82% of cases. Isolated endocardial ablation may be unsuccessful, in such cases epicardial mapping and ablation might be useful.

Aims:To perform the analysis of adverse events (AE) rate and trends of physiologically meaningful parameters in patients with cardiac implantable electronic devices (CIEDs) with the mobile remote monitoring option.

Methods:In 9 clinical centers of the Russian Federation and 2 clinical centers of the Republic of Kazakhstan, 126 patients with an implantable cardioverter-defibrillator (ICD) or a pacemaker (PM) equipped with the Home Monitoring (HM) technology (BIOTRONIK, Berlin, Germany) were enrolled. Based on the daily data transmission, all alarm alerts, all HM options changes and all AE were recorded with dated alert content and undertaken measures.

Results:The study patients, followed up at least for one year, experienced 42 adverse events (AE), of which 26 were serious AE (SAE) and 3 SAE were defined as device-related (SAED). ICD patients (N=90) with concomitant coronary artery disease (CAD) had a statistically significantly higher SAE prevalence (p=0.0249). Patients with CRT-D had a lower SAE rate than patients with dual- or single-chamber ICD (р=0.046). Downloads of Home Monitoring parameters for retrospective mathematical analysis were available for 60 ICD patients, of which 47 had episodes of ventricular tachycardia (VT), ventricular fibrillation (VF) and/or atrial tachyarrhythmia (AT). Machine learning analysis of the trends of the physiologically meaningful parameters revealed correlations between changes and arrhythmia episodes, with the random forest and gradient boosting methods demonstrating the random effect of the results.

Conclusion:Home Monitoring of CIED patients enables the evaluation of different devices applications and their clinical advantages. This might implement the prevention of adverse events and iatrogenic effects of pacing. Based on daily transmission of physiologically meaningful Home Monitoring parameters, the study results demonstrate the feasibility of developing a prediction algorithm for adverse events.

Estado y educación en América Latina a partir de su independencia (siglos XIX y XX)
Authors: Ossenbach Sauter Gabriela
Published: November 2020

El modelo de Estado que surge en Iberoamérica tras el acceso a la independencia, asume pronto las competencias educativas, en detrimento de la Iglesia. Desde esta plataforma, la sociedad se seculariza, se afirma el concepto de nación y aparece una clase media que encuentra en la educación un factor de ascenso social. Al mismo tiempo, aunque indirectamente, también contribuye al progreso económico, a medida que se inician los procesos de industrialización y diversificación productiva. Sin embargo, según la autora, en el momento presente la educación pública sufre un progresivo deterioro como consecuencia de la crisis económica. Esta circunstancia genera problemas de integración política y social, retroceso de las clases medias y falta de cualificación de la fuerza de trabajo, que lastra las posibilidades de desarrollo económico.

As mudanças profundas pelas quais vem passando o mundo, nesta segunda metade do século, produziram transformações na prática social e no trabalho. A educação, que por muito tempo as desconheceu, não pôde mais ficar alheia a elas. Por isso verificamos em todo o planeta uma grande inquietação nos meios ligados ao setor educacional, provocando reformas que buscam sua adequação às novas exigências.

A educação dita secundária ou secundária superior, a que corresponde o ensino médio no Brasil, é a grande questão com que se debatem atualmente os sistemas educacionais. Como conciliar os objetivos de preparação para o prosseguimento de estudos, de preparação para o trabalho e de desenvolvimento pessoal nos cânones contemporâneos? Que vínculos estão sendo estabelecidos entre a educação geral e a educação profissional? Os grandes desafios que esses sistemas enfrentam assumem na realidade brasileira características específicas de um país que está passando por grandes transformações. Os sistemas educacionais estão obsoletos quer na sua concepção, quer nas possibilidades de trajetos que oferecem ou ainda no estágio tecnológico em que se encontram, embora que haja exceções. A estrutura educacional e o modelo de oferta têm que ser construídos de forma bastante flexível para atender a diferentes situações no tempo e no espaço, considerando tanto as rápidas mudanças tecnológicas e as necessidades da vida cidadã como as tendências regionais e do mercado internacional.

Published: November 2020

Tidak banyak dari kita yang menyadari bahwa sebenarnya setiap individu memiliki jebakan yang menempel dalam diri mereka. Kebanyakan dari itu belum sepenuhnya menghilang atau bahkan belum bisa diobati. Terkadang banyak dari kita tidak menyadari adanya jebakan hidup yang mengekang hidup kita. Jeffrey Young, Ph.D and Janet Klosko, Ph.D, (2013) menjelaskan konsep life trap atau jebakan kehidupan. Di dalam buku tersebut jebakan kehidupan digambarkan sebagai pola hidup negatif yang terjadi berulang-ulang sehingga menghambat kita mencapai apa yang kita inginkan. Life Traps yang paling sering dialami oleh setiap individu dikelompokkan menjadi 11 macam, yaitu : Abandonment, Mistrust Abuse, EmotionalDeprivation, Social Exclusion, Dependece, Vulnerability, Defectiveness, Failure, Subjugation, Unrelenting Standart, Entitlement. Tujuan penelitian ini untuk mengetahui jebakan hidup di dalam lingkaran kehidupan manusia sejak lahir hingga dewasa agar setiap individu lebih mengerti dimana posisinya dan apa jebakan yang masih mengekangnya dengan harapan ke depannya setiap individu bisa lebih mengerti bagaimana cara menghadapi jebakan hidup tersebut dan menemukan jalan keluar terbaik demi mencapai kesejahteraan hidup. Metode yang digunakan adalah kajian literatur. Hasil penelitian menunjukkan bahwa lingkungan, mindset, pola asuh, dan karakteristik kepribadian mempengaruhi munculnya jebakan hidup dari setiap individu.

Published: November 2020

The purpose of this research has been to study the willingness to pay for accommodation in green hotels which are strictly following environmentally friendly policies. Questionnaire has been used as a tool to collect data from the people who stayed or have used other services of green hotels. In total, 385 guests in 19 Thai hotels have been surveyed. The results show that the willingness to pay for a green hotel was at a high level. People in Thailand are ready to choose a hotel that spends extra on environmentally friendly activities and/or environmentally friendly policies. In addition, our research has also found that sex, age and education level of consumers have a significant influence on the willingness to pay for green hotels. The results of this research can be beneficial for academic circles, hotel operators and marketing communicators promoting environmentally friendly hotel policies. Namely, our results can be used while developing marketing communications to attract consumers who are ready to choose green hotels.
Floating zone silicon wafer bonded to Czochralski silicon substrate by surface-activated bonding at room temperature for infrared complementary metal-oxide-semiconductor image sensors
Authors: Koga Yoshihiro , Kurita Kazunari
Published: November 2020

We propose to use a bonding wafer as an alternative epitaxial wafer with an extra thick epitaxial layer of more than 100 μm thickness to fabricate vertical time-of-flight (TOF) complementary metal-oxide-semiconductor (CMOS) imaging sensors that can detect infrared (IR) radiation of wavelength greater than 1120 nm. This bonding wafer comprises a floating zone (FZ)-grown silicon wafer bonded to a Czochralski (CZ)-grown silicon substrate by room-temperature surface-activated bonding. Because the device-fabricating region is formed by bonding the FZ-grown wafer to the CZ-grown silicon substrate at room temperature, the oxygen concentration in this region is decreased to less than that in an epitaxial wafer. In addition, our bonded wafer can have a strong gettering capability for oxygen and transition metals (nickel, copper, and iron) in the bonding interface. Furthermore, the bonded wafer can inhibit out-diffusion of oxygen or transition metal to the device-fabricating region from the CZ-grown silicon substrate, and the device-fabricating region can have fewer impurities after fabricating the devices in the bonded wafer. Therefore, we consider that this bonded wafer can be fabricated by the simple processes of bonding and grinding (polishing) at room temperature without thermal stress, and this method is effective for decreasing the dark currents and white-spot defects generated owing to the presence of oxygen or transition metal, which are undesirable in advanced TOF-CMOS imaging sensors of a vertical structure.
Investigating The Unexpected Price Plummet And Volatility Rise In Energy Market: A Comparative Study of Machine Learning Approaches
Authors: Ojugo Arnold Adimabua , Otakore Oghenevwede Debby
Published: November 2020

The energy market aims to manage risks associated with prices and volatility of oil asset. It is a capital-intensive market that is rippled with chaos and complex interactions among its demand-supply derivatives. Models help users forecast such interactions, to provide investors with empirical evidence of price direction. Our study sought to investigate the reasons for the unexpected plummet in price of the energy market using evolutionary modeling – which seeks to analyze input data and yield an optimal, complete solution that are tractable, robust and low-cost with tolerance of ambiguity, uncertainty and noise. We adopt the Gabillon’s model to: (a) predict spots/futures prices, (b) investigate why previous predictions failed as to why price plummet, and (c) seek to critically evaluate values reached by both proposed deep learning model and the memetic algorithm by Ojugo and Allenotor (2017).

Authors: Atuahene Sampson , Kong Yusheng , Bentum-Micah Geoffrey
Published: November 2020

The outbreak of the new coronavirus (COVID) started in December 2020. By far, the COVID-19 has affected over 26,547,419 individuals worldwide, with 874,424 deaths and 18,732,160 recoveries as of August 2020. The research aims at identifying the effects of COVID-19 on education sector management pointing out success stories of countries that have been able to overcome the hindrances that the pandemics have brought on the management of the various sectors of education, which other countries may adopt. From our analysis, we discovered that combating COVID-19; demands syndrome surveillance, immediate isolation of patients, and strict enforcement of all contact-persons, quarantine, and country lockdown/border closure. We further outlined ways in which COVID-19 (coronavirus) epidemics affect the education of emerging economies. Our article then summarizes the evidence of a negative impact that is likely to disrupt the education system and identifies some policy responses to mitigate the effects. We again realized that what could save education (school system) now and in the future is online learning which authorities should make available, accessible, and affordable especially for developing countries.
Sectorial Output Growth and Commercial Bank Credit Nexus in Nigeria
Authors: Abina Adedigba Praise , Obi Emeka
Published: November 2020

This study investigates the nexus between sectorial output growth and commercial bank credit in Nigeria. Sectorial output growth was broken down into three different proxies which include production sector, Commercial sector and Service sector contribution to gross domestic product while bank credit to production sector, general commerce and service sector served as the independent variables which are used to proxy commercial bank credit. The study made use of secondary data obtained from Central Bank of Nigeria Statistical bulletin for the period 1981 to 2019. It employed Descriptive Statistics, Phillips-Perron (PP) Unit Root Test, Simple Regression Analysis and Granger Causality Test. The Granger Causality result showed that bi-directional causality is identified in the three models while there were positive and significant relationship between bank credit to production sector, general commerce, service sector and production sector contribution to gross domestic product, general commerce sector contribution to gross domestic product and service sector contribution to gross domestic product respectively. The paper therefore recommends that the regulatory authorities should prioritize more on increasing and easing the requirements needed from deficit spenders to secure credit from commercial banks in Nigeria.

Published: November 2020

The purpose of this study is to analyze the role of the boarding school leadership in improving the quality of human resources as a whole. The contribution of human resources is very important in the progress of this boarding school. The method used is through a phenomenological approach, in which the researcher is directly involved in the struggle of society and the students directly. Researchers observe and analyze and interview the parties who are directly related. The success of building a nation, starting from the development of human resources, HCL (Human Capital Index) plays a very important role in the development of civilization towards SGDs. The HCL component, which includes education, health and social security, has been implemented in the Idrisyah Islamic boarding school, as a Tarekat. The application of the HCL principles greatly impacts on sustainable human development. Tarekat in Indonesia that apply it because they still apply spirituality of worship vertically, the majority do not have an impact on socio-culture, economy, development and others and as a result unemployment, poverty is not significantly reduced. This tarekat is a new trend in socio-societal change and as a Sufistic movement in Indonesia.
A Simultaneous-Equation Model of Estimating Exchange Rate Pass-Through in Malaysia
Authors: Hsing Yu
Published: November 2020

Based on an extended IS-LM-AS model, this study finds that a 1% depreciation of the Malaysian ringgit tends to cause the CPI to rise by 0.1194%. Moreover, more M2 money supply, a lower government borrowing as a percent of GDP, a higher crude oil price, a higher U.S. CPI, and a higher expected consumer price index tend to raise Malaysia’s CPI. Therefore, exchange rate pass-through (ERPT) to the consumer price in Malaysia is partial and incomplete.
Moving Average Convergence-Divergence (MACD) Trading Rule: An Application in Nepalese Stock Market "NEPSE"
Authors: Vaidya Rashesh
Published: November 2020

There are two types of analysis done for a stock market. One is fundamental analysis, where an investor looks at an intrinsic value of the stock, and another is technical analysis, where investors determine the future trend of the market looking at the current pattern or trend of the market. This paper is focused on one of the technical analysis tools, i.e., Moving Average Convergence-Divergence. It is a tool based on the three exponential moving average (9-12-26 EMA Rule). The MACD analysis, with the help of a single line, was helpful to find out the exact bullish and the bearish trend of the Nepse. A signal line is a benchmark to determine the stock market moving either to a bullish or bearish trend. It can help an investor, where the market is going in a direction. A market convergence, divergence, and crossover were better identified with the help of the MACD histogram. The paper found that the Nepse return was stable for a very minimal period from 1998-99 to 2019-20. The shift from the bullish to bearish or vice-verse were seen easily identified with the help of a MACD histogram. Finally, a better-combined knowledge of moving average and candlestick chart analysis will help an investor, to put a clear picture of a market trend with the help of MACD analysis.
