Published: June 2022

There are very few studies in Vietnam on the application of text mining in finance and Vietnamese language processing. The origin of this study comes from one of the leading studies on the use of machine learning to analyze text data from 4 well-known online newspapers in Vietnam to forecast the increase, decrease and neutrality of the VN-Index one day in advance. This study used nearly 70,000 articles from four reputable and reliable online newspapers in Vietnam as input data for machine learning models. These were: decision trees, random forests, KNNs and SVMs. After selecting the best model (SVM) and the best dataset (Vietstock), the techniques used to dig deep and refine the findings raised the accuracy to 60.1%. The end result is solid evidence that news about the financial and stock situation in the popular press affects the price movements of the VN-INDEX and the Vietnamese stock market.
Why is African Trade so Limited?
Authors: Bao Nguyen Duc , Bouët Antoine
Published: June 2022

This paper studies the determinants of the low participation of African countries to international trade. We point out the under-trading status of Africa, then we estimate a gravity equation in order to identify the determinants of trade in general. As we characterize the level of these explanatory variables in Africa as compared to the rest of the world, we identify the main variables behind the low participation of Africa to trade in general. Usual gravity factors play an important role, but we show that non-tariff measures and the quality of infrastructure and institutions are important. Import duties does not significantly impede African exports. We test the impact on African countries’ exports of a counterfactual scenario where infrastructure and institution variables in African countries are changed to the world average and conclude that the most important leverage effect to be expected from investment in infrastructure would be from mobile cellular telephone subscriptions. If we consider only countries where exports are positively affected, this counterfactual exercise implies a change by 31.0% of national exports on average by African country. While this result is interesting it has to be considered with caution since the exact form of the relation between trade and mobile cellular telephone subscriptions is largely unknown.

Corrections to the article: https://doi.org/10.25305/unj.234154
In the article by V.V. Medvedev et al., published in UNJ № 3 in 2021, the source number 92 from the reference list does not support the statement given in the appropriate place in the text. Instead, we offer the reader two other works that mention the presence of posterior median spinal artery in the adult rat - D. Mazensky et al. (2017) and O.U. Scremin (G. Paxinos, ed.; 2015, p. 1003, 1005). In most works on this topic (Z. Zhang et al., 2001; Y. Cao et al., 2015; P. Li et al., 2020) the dorsal median vein is considered as the median vessel of the posterior surface of the rat spinal cord, and as in humans, describe 2 parallel dorsal spinal arteries. At the same time, D. Mazensky et al. (2017), sharing the opinion of O.U. Scremin (2015), mention 3 dorsal spinal arteries of the rat, in particular the median one. Taking into account that, from our experience, damage to the median vessel of the posterior surface of the spinal cord is accompanied by its rapid edema and irrepversible deep deficit in the motor function of both hind limbs of the animal, we consider it necessary to draw the reader's attention to this feature of the anatomy of the spinal arteries of an adult rat.

Spectroscopic Tools to Investigate the Electrochemical Doping Kinetics and Efficiency in Organic Semiconductors
Authors: Bardagot Olivier , Banerji Natalie
Published: June 2022

Understanding the electrochemical doping of organic semiconductors plays a crucial role in the current development of organic electronics. In this short review, we present how temperature- and time- dependent visible-near-infrared (Vis-NIR) spectro-electrochemistry and terahertz spectroscopy, combined with multivariate curve resolution analysis, can inform on the fundamental mechanisms governing the doping kinetics and efficiency of two archetypal semiconducting polymers (PEDOT and P3HT). We highlight the experimental procedures and data analysis performed to access (i) the thermodynamic parameters driving the extent and dynamics of electrochemical reactions in doped systems and (ii) how the density and nature of charged species (polarons, bipolarons) impact the charge carrier delocalization, effective THz mobility and hence short-range conductivity.
A Density Functional Theory for the Average Electron Energy
Authors: Racioppi Stefano , Lolur Phalgun , Hyldgaard Per , Rahm Martin
Published: June 2022

A formally exact density functional theory (DFT) determination of the average electron energy is presented. Our theory, which is based on a different accounting of energy functional terms, partially solves one well known downside of conventional Kohn-Sham (KS) DFT: that electronic energies have but tenuous connections to physical quantities. Calculated average electron energies are close to experimental ionization potentials in one-electron systems, demonstrating a surprisingly small effect of self-interaction and other exchange-correlation errors in established DFT methods. Remarkable agreement with ab initio quantum mechanical calculations of multi-electron systems is demonstrated using several flavors of DFT, and we argue for the use of the average electron energy as a design criterion for density functional approximations.
Reactive Neural Network Potential for Aluminosilicate Zeolites and Water: Quantifying the effect of Si/Al ratio on proton solvation and water diffusion in H-FAU
Authors: Saha Indranil , Erlebach Andreas , Nachtigall Petr , Heard Christopher J. , Grajciar Lukáš
Published: June 2022

Acidic zeolites are one of the most important catalysts. In many of their catalytic applications, the mode of interaction with water heavily influences their activity, efficiency, and durability as a catalyst. Despite the recent (first principles) computational efforts to understand the mechanistic underpinning of the water-zeolite interactions, it is still prohibitively expensive to carry out comprehensive studies employing realistic zeolitic models. Therefore, we developed a reactive neural network-based potential for aluminosilicate zeolites in the protonic form including their interaction with the aqueous solution that has a capacity to accelerate simulation by orders of magnitude while retaining the reference level of accuracy. To showcase its potential, we used it to determine how multiple factors (aluminum content, water loading and temperature) influence the proton solvation and water dynamics in one of the industrially most important acidic zeolites, the faujasite (FAU). We found that Si/Al ratio is a significant determinant of the water diffusivity, water capacity to solvate protons in the nanopores, and the zeolite hydrolytic stability. We expect that many of these findings are readily extendable to other acidic zeolites in interaction with water.
Development of the technical solution to prevent a single-rotor helicopter from entering uncontrolled rotation
Authors: Ivchin V. A. , Samsonov K. Y. , Kasimov A. M. , Popov A. I.
Published: June 2022

The phenomenon of a single-rotor helicopter entering an unintended left rotation with the further development of an uncontrolled turn periodically arises while operating this type of helicopter, both in Russia and abroad. This phenomenon can lead to serious aviation incidents and even disasters. Currently, there is no unambiguous justification for the phenomenon of "uncontrolled" U-turn and the causes of occurrence, since the operating conditions of the tail rotor (TR), especially at low-speed modes, depend on many factors. These factors include, firstly, wind direction and speed, T/R “vortex ring", as well as the impact of the main rotor vortex trace. One of the explanations for this phenomenon lies in the special specifics of the yaw trim of a singlerotor helicopter, which is provided by the tail rotor. These papers emphasize that the change in wind speed and direction which affects the helicopter, and the TR is the main cause of the unintentional left turn. Currently, there are no tools and methods for determining the wind effect on the TR in order to develop a warning signal for a pilot about a change in the nature of the TR flow and an alert about the occurrence of uncontrolled rotation. This paper proposes the system for measuring the TR air flow using a special sensor that allows us to measure the inductive air flow velocity of a small value in an aerodynamic way without additional various electronic transformations that are inherent in conventional Pitot tube probes. The use of such a measurement system makes it possible to identify the probability of a dangerous situation, to inform the pilot and help him take the proper actions.
Using the simulation program of the DA-42T aircraft central data system operation in the educational process of the university

Published: June 2022

During training sessions in an aviation university, it is advisable to demonstrate samples of aeronautical equipment, individual elements of systems and units or to use some specialized stands and posters. However, when conducting classes online, not all these materials can be used, since it is not always accomplishable to demonstrate them in dynamics and thereby to ensure the students’ complete understanding of the object being studied. The article deals with the issue of enhancing visibility and efficiency of training pilot trainees by using software applications during the educational process, which simulate the operation of the Central Data System, information from which is displayed in the real aircraft in the form of frames on multipurpose displays in the cockpit. Working with the developed program allows student pilots to gain the required practical skills while interacting with the avionics suite. In order to implement the simulation program of the Central Data System operation into the educational process, I-frames, shown on the DA-42T aircraft multipurpose displays, were reproduced. The content of the developed frames completely repeats the DA-42T aircraft indication, which contributes to improving the quality of training and honing practical skills for aircraft operation. The structure and the procedure of designing the program to simulate the Central Data System operation are described. The selection of software for the development of the Central Data System simulation program is substantiated. The feasibility of integrating the developed program into the flight simulator is described. The applicability of using the software program for distance training of aviation specialists, as well as of the implementation of the results obtained into the educational process of aviation universities is provided.
Why worry about financial exclusion?

Published: June 2022

Should policymakers aim to expand access to bank accounts? When financial exclusion is due to frictions that prevent banking from operating efficiently, intervention may be justified. Applying simple economic principles, we highlight possible frictions that may give rise to inefficient exclusion in the United States, and we assess their importance using insights from data and the academic and policy literature.
Geometry Teaching in Transition: An Investigation on the Importance of School Geometry in Primary Education
Authors: Kuzle Ana
Published: June 2022

Mathematics instruction in primary school has been influenced by many policy changes and empirical findings in the previous two decades. Geometry lessons, in particular, were re-evaluated due to a paradigm change and, consequently, were attributed a new meaning within the mathematics curriculum worldwide. The present paper focuses on this paradigm shift in the sense of the evaluation to what extent both the didactical potential and the practical value of geometry instruction in elementary education are currently recognised and utilised by primary grade teachers. In total, 120 primary grade teachers participated in the study. The results showed that there had been positive recognition of the didactical potential of school geometry by the teachers over the previous two decades; however, it lacked actual implementation in school practice for different reasons. The results are discussed not only with regard to the latter of these but also with regard to their theoretical and practical implications.
Scale and Impact of Sports Stadium Grow Lighting Systems In England
Authors: Geliot Steve , Coesfeld Jacqueline , Kyba Christopher C. M.
Published: June 2022

Recently, many sports stadiums have begun using high power lighting systems to help the grass grow on the playing surfaces. These lights supplement winter sunlight, which is sometimes insufficient due to the low elevation of the sun and shading from the surrounding walls. In many stadiums, grow lights are operated at night, and the waste light emissions from these stadiums are extraordinary in comparison to most other areas in the cities in which they are located. Here we present space-based observations of the radiance of fourteen stadiums located in towns and cities of varying sizes and in varying geographical locations across England which each have a Premier League football stadium. We show that stadiums have dramatically brightened (typically by factors of 2-5) in recent years compared to the situation in 2012. We also show that stadiums are often responsible for an important fraction of the total light emission of the cities they are in (often 10% or more, and in one case up to 30%). Because the light emissions from many English towns have been reducing in recent years, the overall fraction of light due to the stadiums is increasing. In some cases, total city emissions have actually increased due to the stadiums, undermining the environmental impact of reductions in radiance in the rest of the community. We believe that stadium grow lights are an excellent target for sustainable lighting initiatives, both because of their considerable environmental impact (especially when located near sensitive areas) and the possibility of high profile and successful waste light mitigation projects.

Published: June 2022

Malaysia’s commitment to expanding its pineapple production has increased the amount
of pineapple waste production in the country, especially in the state of Sarawak. This has
raised the alarm regarding the proper management of pineapple waste among the local
farmers. Therefore, the current study was carried out to investigate the current practices of
pineapple waste management and to identify the challenges in managing the pineapple
waste among pineapple smallholders in Samarahan, Sarawak. The data was collected from
123 pineapple farmers by employing a close-ended survey questionnaire. The pineapple
smallholders were selected using the random sampling method and the data were analysed
using descriptive analysis. The findings revealed that the pineapple smallholders in
Samarahan employ several practices for managing the pineapple waste which include
using the pineapple crown as new planting material, animal feed and compost material.
Moreover, the study has also identified several challenges in managing the pineapple
waste such as lack of time, high cost, difficulty in finding the buyer of the waste product,
shortage of labour, the waste product attracts pests and diseases, and it produces foul smell
which discourages them in managing the pineapple waste. Therefore, the relevant
agencies should provide guidance to the local pineapple growers in managing pineapple
waste through sustainable waste management practices.
Effects of gamma irradiation on agromorphological characteristics of chili
(Capsicum annuum L.) var. Kulai
Authors: A. Shamsiah , O. Norumaimah , F.S. Nur Amalina , Susiyanti  , Abdul Rahim H. , Shuhaimi S.
Published: June 2022

The increasing demand for chilli has drawn the interest of chilli breeders to improve the
production of this crop. Mutation breeding is applied in many crops improvement
programs as it can rapidly create the variability of inherited traits in crops. This study
evaluates the effects of irradiation doses of radioactive cobalt (60Co) γ rays on seed
performances, morphological characteristics and yield of chilli (Capsicum annum L.) var.
Kulai grown under laboratory and glasshouse conditions. The chilli seeds were treated
with gamma radiation at 0, 20, 40, 60, 80, 100, 200, 300, 400, 500 and 600 Gy. The effect
of gamma-rays was assessed towards germination, survival rate and several morphological
characteristics. From the observation, seeds from all treatments were germinated (100%)
in 10 days. However, the gamma radiation affects the survival rate, fruit length, fruit
weight, plant height, and most of the results were lower upon exposure to higher doses
particularly 100 Gy and above. Germination rate, plant height, plant survival rate and
other morphological characteristics of the irradiated plant were observed to improve at
lower doses (40, 60 and 80 Gy). Apparently, lower gamma-ray doses (<100 Gy) were
more suitable to study the effect on seed germination as well as other morphological
characters of Capsicum annuum L. especially Kulai variety. Mutagenic dose of 300 Gy
was estimated as the LD50 for Kulai variety. The findings of this study provide useful
information for mutation breeding in Capsicum annuum L. using gamma radiation for
future breeding programmes in chilli.

ICT4D Research in Developing Countries: A Call for Pragmatism Approach
Authors: Kamau Gabriel Ndung'u
Published: June 2022

Today, Information Systems research and in particular in the area of ICT4D in developing nations is dominated by positivism and interpretivism paradigms.  Information systems contributions are influenced by historical, cultural, and political contexts in which it is done. Researchers in this area question the appropriateness of positivism and interpretivism philosophical foundations to conduct ICT4D research.  This paper explores the use of pragmatism as an alternative research paradigm to that can be employed to understand the state of the ICT4D research. Research drawing explicitly on pragmatism is still relatively rare. The paper reviews the pragmatism in terms of its ontology, epistemology, axiology and methodology and its value in the ICT4D research discipline. As a new paradigm, pragmatism disrupts the assumptions of older approaches based on the philosophy of knowledge, while providing promising new directions for conducting and understanding the nature of research in the area of ICT4D in developing countries. It is anticipated the readers of the article to make a more informed choice for themselves on whether or not to pursue the path ofpragmatism their own research. KeywordAxiology, epistemology, ICT4D, methodology, ontology, pragmatism, research paradigms
