Published: November 2023

Accuracy is the primary focus in prediction research. Optimization is conducted to improve the performance of prediction models, thereby enhancing prediction accuracy. This study aims to optimize the Facebook Prophet model by performing hyperparameter tuning using Bayesian Optimization to improve the accuracy of USD Index Value prediction. Evaluation is conducted through multiple prediction experiments using different ranges of historical data. The results of the study demonstrate that performing hyperparameter tuning on the Facebook Prophet model yields better prediction results. Prior to parameter tuning, the MAPE indicator metric is 1.38% for the historical data range of 2014-2023, and it decreases to 1.33% after parameter tuning. Further evaluation shows improved prediction performance using different ranges of historical data. For the historical data range of 2015-2023, the MAPE value decreases from 1.39% to 1.20%. Similarly, for the data range of 2016-2023, the MAPE decreases from 1.12% to 0.80%. Furthermore, for the data range of 2017-2023, there is a decrease from 0.80% to 0.76%. This is followed by the data range of 2018-2023, with a decrease from 0.75% to 0.70%. Lastly, for the data range of 2019-2023, there is a decrease from 0.63% to 0.55%. These results demonstrate that performing Hyperparameter Optimization using Bayesian Optimization consistently improves prediction accuracy in the Facebook Prophet model.

Social media has exerted a significant influence on the lives of the majority of individuals in the contemporary era. It not only enables communication among people within specific environments but also facilitates user connectivity in the virtual realm. Instagram is a social media platform that plays a pivotal role in the sharing of information and fostering communication among its users through the medium of photos and videos, which can be commented on by other users. The utilization of Instagram is consistently growing each year, thereby potentially yielding both positive and negative consequences. One prevalent negative consequence that frequently arises is cyberbullying. Conducting sentiment analysis on cyberbullying data can provide insights into the effectiveness of the employed methodology. This research was conducted as an experimental research, aiming to compare the performance of Random Forest and Random Forest after applying the Particle Swarm Optimization feature selection technique on three distinct data split compositions, namely 70:30, 80:20, and 90:10. The evaluation results indicate that the highest accuracy scores were achieved in the 90:10 data split configuration. Specifically, the Random Forest model yielded an accuracy of 87.50%, while the Random Forest model, after undergoing feature selection using the Particle Swarm Optimization algorithm, achieved an accuracy of 92.19%. Therefore, the implementation of Particle Swarm Optimization as a feature selection technique demonstrates the potential to enhance the accuracy of the Random Forest method.
The Correlation between Students’ Grammar Proficiency and Speaking Fluency: A Study in English Education Study Program
Authors: Lekatompessy Felicia Miranda
Published: November 2023

Speaking as the part of four main skills in English can be considered as the most demanding yet the most difficult skill to be mastered. Thus, several ways to master speaking have been researched by experts, one of which is in terms of fluency. As fluency tends to focus on students' ability to speak fluently, subtly, and spontaneously, the grammar aspect is rarely considered as one of the aspects that is related to fluency because grammar is closely related to accuracy. Concerning the aforementioned fact, the objective of this case was to examine the correlation between English grammar proficiency and speaking fluency. The researcher used quantitative method and correlation research design. The population was 103 of 2021 batch students, at English Education Study Program of Pattimura University of which the sample was 31 students from class A. The instruments were in the form of grammar written test and speaking oral test. The student’s grammar proficiency scores (X) and the student’s speaking fluency (Y) were analyzed and it is found that the distribution of data was normal and linear. The result of data analysis showed that the significant value was at 0.001 and the correlation coefficient was at 0.853. The interpretation of the relationship is positive correlation and the strength of correlation is perfect. Consequently, the alternative hypothesis (Ha) is accepted which indicates positive and significant correlation between students’ grammar proficiency and their speaking fluency. These findings suggest that it is important for students to increase their grammar proficiency level in order to improve their speaking fluency.

Published: November 2023

This study compared the egg production, defective egg rate, and mortality of commercial laying hens based on strain and cage type under commercial farm conditions. Two commercial white egg-laying strains (Hy-line and Super Nick) and two brown egg-laying strains( Nick Brown) were housed in conventional (32409 cm2) and enrichable (7200 cm2) cage systems. These layer flocks were visited weekly from 18 to 56 weeks of age, and data were collected on daily egg production, mortality, and the number of dirty and cracked eggs. Both the strain and cage type significantly affected hen-day and hen-housed egg production. Egg production was higher in conventional cages and for brown egg strains. The strain's impact on weekly mortality became insignificant after 32 weeks, while the highest mortality rates were observed in the enrichable cages. Significant differences were in the weekly dirty and cracked egg rates between layer strains and cage types. For enrichable cages and white-laying strains, the rate of dirty and cracked eggs was higher. The interaction of strain and cage type affected egg production, the rate of cracked and dirty eggs, and mortality. As a result, the brown egg-laying strain hens exhibited higher egg production than the white strain hens, and in overcrowded and enrichable that is non-enriched cages, lower egg production, higher mortality rates, and a higher rate of dirty and cracked eggs were observed.

يعد (الوكز) من النظريات الجديدة التي تعد واضحة في القطاع الاقتصادي والصحي والتعليمي؛ نظرًا لكثافة الدراسات حوله وتطبيقاته، إلا إنّه لم يدخل حتى الآن في دراسات الوقاية من الجريمة، ويأتي مقترح استعمال نظرية الوكز في الوقاية من الجريمة من أجل تصميم سياسات أمنية فاعلة وبتكلفة أقل، وتنفيذها بأساليب غير مادية، ومن أجل إثراء التنظير في مجال الوقاية من الجريمة، وتقديم آليات عصرية وفعّالة وقابلة للتنفيذ.
وقد عالجت الدراسة موضوعها بمنهج (المراجعة التكاملية) الذي يعد شكلًا مميزًا من أشكال البحث التي تولد معرفة جديدة حول موضوع ما من طريق مراجعة وانتقاد وتوليف الأدبيات حول الموضوع بطريقة متكاملة بحيث يجري إنشاء أطر ووجهات نظر جديدة حوله.
وقد استندت الدراسة إلى أدبيات علم الاقتصاد السلوكي، مع التركيز على ثلاث نظريات أساسية وحديثة، هي: الوكز، والتفكير السريع والبطيء، وفوضى التحيز. وجميعها تؤكد أنّ الإنسان العادي يتصرف بتلقائية، ويتخذ قراراته اليومية وفق المتاح، من دون التفكير والتأمل، وهي بهذا تحمل سمات يمكن للباحث الأمني أن يوظفها في الوقاية من الجريمة، وتصميم السياسات الأمنية.
وأكدت كثير من نتائج دراسات استعمال الوكز ونظريات الاقتصاد السلوكي في الوقاية من الجريمة خفض معدلات الجريمة، وأثمرت عن نتائج إيجابية من الوقاية من الجريمة، بدلًا من مكافحتها، وبخاصة في مجال التخطيط الحضري وتصميم المتاجر وتشجير الشوارع وإنارتها ورصفها، ممَّا يشجع على إقبال الأفراد عليها، ويُحدث تفاعلًا اجتماعيًّا طبيعيًّا يمنع من تحفيز المجرم على ارتكاب جريمته.
وتوصي الدراسة بمنح المزيد من الاهتمام بدراسة استعمالات نظرية الوكز، وتطوير تصميم السياسات الأمنية في الوقاية من الجريمة، ودعم الدراسات الأمنية الحديثة، ودراسات السياسات الأمنية.

Published: November 2023

Switching the operation of railway equipment to life cycle contracts and confirming its safety compliance with industry technical regulations in the absence of a legislative framework for the recall of substandard products entails the need for a more thorough analysis of resource indicators of structural components of rolling stock and track superstructure. From this point of view, the state of the existing regulatory framework for confirming the strength and service life criteria of load­bearing elements of rolling stock and track, the influence of the regulatory «guillotine» and the general transition from the system of Soviet state standards GOSTs and strength rules to modern approaches of certification and differentiation of such concepts as «standard» and «supporting standard».Trends in moving away from classical bench testing methods towards introduction of a resource-based approach with defectiveness assessment are shown using examples of previously carried out research on safe operation of ER200 bogie frame and on the transition to domestic cassette bearings as part of import substitution, currently carried out for different types of rolling stock.Based on the new methods and approaches, it is possible to consider longer periods of operation, reasonably assess the extension of service life, or introduce resource-restoring technology, ensuring further safe operation. As part of these new trends, a transition is being made to modern modelling methods for assessing product safety, concepts such as «virtual sensor» and «virtual train-track system» are being introduced. It is shown that a reasonable combination of full-scale operational tests and virtual digital modelling makes it possible to offer reliable estimates of service life and safety indicators at the design and operation stages in a short time.

Published: November 2023

The article presents the results of a scientific study of current issues of risk management associated with ensuring safe operation of unmanned vehicles, obtained by the authors as a result of implementation of the second stage of a scientific project supported by the Russian Science Foundation. The conclusions presented in the article are based on the results of a study of legal and organisational problems of ensuring the safe use of unmanned vehicles in a metropolis, carried out during the first stage of the project.The study confirmed the authors’ assumption that solving the problem of ensuring the safe use of unmanned vehicles is possible based on scientific research into the risks arising during their operation. It is substantiated that identification, differentiation, monitoring of risks determined by appearance of unmanned vehicles on highways is a necessary condition for development of a scientifically based system of legal measures of general and private prevention, including measures of legal liability for relevant offenses, based on categorisation of risks and threats of violation of mandatory requirements adopted to ensure transport safety and traffic management using this type of vehicle.The fundamental provisions are analysed and comprehended underlying the application of the risk­based approach in homogeneous and single-type social relations.

Authors: Kurganov V. M. , Gryaznov M. V. , Dorofeev A. N.
Published: November 2023

The objective of the study is to establish the origin and evolution of the term «logistics», understood as management of material flows and stocks. The historical-genetic method and content analysis were used in the study of available sourcesThe inconsistency of assumptions about the origin of the name «logistics» in the modern interpretation from ancient Greece and the Byzantine Empire is shown. There is also no connection between the mathematical logic developed by Leibniz and the content of logistics in economics and military affairs. The illegitimacy of explaining the evolution of the term «logistics» by random coincidences of words that are homonyms and related to different historical eras and countries has been established.The priority of G. V. Jomini in formulation of the principles of logistics in his works on the art of war, written after emigration to the Russian Empire, is confirmed. Due to the spread of Jomini’s works in the countries of the world, logistics began to develop in its modern form, initially in the military sphere, and then in economic activity.The reasons that led to intensive development of logistics during the Second World War and in the post­war period are systematized. Differences in priorities during these periods in the countries of the world are studied. Two main trends were identified, one of which was to use the competitive advantages of logistics in a market environment, and the other to ensure spatial connectivity and transport accessibility of territories.

Authors: Lyashenko A. Yu.
Published: November 2023

For the road industry, it is quite important to reduce costs and energy consumption, as well as energy recovery in process plants. To solve this problem at one of the stages of the industrial process, which is production of road metal, an important material for road construction, it is proposed to develop autonomous power unit based on recuperation of the kinetic energy of dump trucks, namely a unloading and screening unit of crushing and screening plant with non-volatile drive of auxiliary equipment.A non-volatile unloading and screening unit separates the feedstock at the primary stage of production in a non-volatile operating mode, using recovery of the kinetic energy of trucks been unloaded. After loading rubble sandstone into the receiving hopper, the unit activates the process of material segregation into coarse and fine fractions. The respective fractions are fed to the appropriate feeders for subsequent technological processing. The advantage of the unit is the autonomy of the vibrator and feeders’ drives, which helps to raise the efficiency of the process of unloading and separation of the rubble sandstone and reduce energy costs for production of the finished product.The evaluation of the functional capabilities of the non-volatile hydraulic drive of the unloading and screening unit was carried out for hydraulic motors of the screening and conveying equipment. The apron feeder of KM PP-2–10–60B type providing a continuous and uniform supply of feedstock was assumed as the basic equipment, and the volume of working fluid in the hydraulic accumulator supplied by hydraulic jacks was calculated. The results showed that two hydraulic jacks with the specified parameters can provide the required flow and allowed determining the amount of energy stored in the accumulator during feedstock loading. The calculated power of the hydraulic motor allows its use in the feeder. The economic efficiency of the installation with an autonomous drive is estimated considering the mode of operation, the number of shifts and the tariff for electricity.

Published: November 2023

Transport systems, in particular civil aviation, occupy an important place in development of any modern state. The effective design of such systems has a positive impact on the socio­economic component of any country. The quality of the transport system can be assessed through the population’s access to it. At present, one of the important problems of long-term development of the air transport system of the Russian Federation is definition of a universal indicator that allows assessing access to transport and its possible target standard.The article proposes an approach for assessing access to air travel using mathematical modelling. Two indicators are used as a criterion: a potential number of passengers in the gravitation zones of each airport and a passenger’s time being in the system. A methodology for determining the proposed indicators has been developed. The application of the approach of assessment of access to air travel is demonstrated on the 2019 network.An example of a target (simulated) network of domestic passenger air transportation is also given, which allows to significantly increase access to air travel. Based on the results obtained, the paper proposes target standards for the values of access to air travel for the Russian Federation.

Authors: Dadon Kotel
Published: November 2023

Problematika pobačaja sporna je i osjetljiva. Otvara brojna pitanja i nedoumice iz raznih područja, a često je i u fokusu javnosti širom svijeta. U ovom se članku raspravlja o pobačaju u judaizmu. Analizirat će se različiti izvori judaizma koji se bave pitanjem pobačaja, od pisane do usmene Tore, što uključuje literaturu Talmuda, Mišne, Midraše, kao i kasnu rabinsku literaturu. Osim teoretske i analitičke rasprave o apstraktnim principima vezanima uz pobačaj, autor će se osvrnuti i na praktične aspekte, stav židovskoga zakona prema pobačaju u raznim slučajevima – od onih kada su razlozi pobačaja vezani uz majku, kao što su izravna ili neizravna tjelesna ili mentalna opasnost za život majke zbog trudnoće, preko razloga koji su vezani uz fetus, kao što je malformacija fetusa koja je možda uzrokovana majčinim zdravstvenim stanjem ili nekom nasljednom bolešću fetusa, do slučajeva kada je odluka o pobačaju uzrokovana nekim vanjskim čimbenikom, primjerice socioekonomskom situacijom, silovanjem, prostitucijom ili incestom. U završnom se dijelu članka istražuje pitanje pobačaja u vrijeme holokausta.
Girardovo čitanje Camusova Stranca
Authors: Tomić Marinko , Pavešković Antun
Published: November 2023

U radu se prikazuje Girardovo tumačenja Camusova Stranca. Girard nastoji pokazati da je Camusov prvi roman napisan sa sasvim određenim ciljem: izazvati simpatiju prema običnom čovjeku i mržnju prema sustavu, »sucima«. Glavni lik, Mersault nije tek utjelovljenje apsurda, kako se obično misli, već odraz određenog autorova angažmana. Skrivena pozadina Stranca, prema Girardu, izlazi na vidjelo u Padu, trećem Camusovu romanu u kojem se pisac kritički osvrće na svoje dotadašnje stvaralaštvo i prepoznaje pristranost prijašnjih djela. U obliku alegorije Pad otkriva naličje Stranca, tj. dobro prikrivenu želju da se kao »sudac sudaca« bude iznad sviju, u poziciji moralne superiornosti. Girard smatra da se analizom narativnog toka Stranca upotpunjuju navedena zapažanja. Kritička analiza ukazuje na naracijsku nedosljednost u Strancu koja se najbolje ogleda u »nedužnom ubojstvu«. Ta osebujna zamisao ne može prikriti središnje proturječje radnje, odnosno ne uspijeva mirnog solipsista iz prvog dijela romana preobraziti u mučenika društva, iz drugog. Solipsizam Camusova junaka nadovezuje se na baštinu romantizma. Kao izdanak kasnog romantizma, Mersault nosi u sebi središnju proturječnost romantičkog junaka: unutarnju podijeljenost žudnje tj. istodobnu želju da se bude osamljen i društveno priznat. Prema Girardu, romantičarska ambivalentnost nalikuje neurotičnom i nezrelom ponašanju.
Human and ethical risks of digitalization
Authors: Bezklubaya Svetlana A.
Published: November 2023

Digitalization as a direct expression of global information business is the reason for modern civilization’s transformation. The total commercialization of information technologies’ super-productivity turns humans into progress »costs«, devaluing their creative power, morality and ethics. Therefore, the object of this study is to be a person in the face of growing ethical risks caused by ever-accelerating digitization and information processes. The purpose of the work is to identify the problems of ethics and ethical risks as specific and most significant for the digital society. It also shows the main approaches to their solution. An analysis of a person’s consumer attitude to technical achievements reveals the reasons for spirituality destruction as the basis of human integrity. This is due to changes in communication forms – language, art, education, and religion. Digitalization as open information makes it possible to specify ethical risks as a reflection of a human’s life situation. Values and meanings play a crucial role. Digitalization’s ethical risks are identified: privacy, inclusiveness, security, trust, and fairness. The main approach to preventing digitalization ethical risks is the establishment of a techno-humanitarian balance or the development of adequate cultural regulators (human-centricity, overcoming digital inequality) that oppose the growth of destructive power of new technologies in relation to universal human values and humaneness. The methodological basis of the study was the philosophical discourse of consequentialism. This determines the main condition for technology development to find a balance between risk and benefit and cultural and philosophical reflection. The theoretical conclusions contained in this work open up new opportunities for science to concretize practical approaches to solving moral problems and ethical risks in human existence. This is in the era of digital culture transformation.

Further evidence for the bidimensionality of the components model of addiction: a reply to Amendola (2023)

In our original research article entitled “Deconstructing the components model of addiction: an illustration through “addictive” use of social media” (Fournier et al., 2023), we showed that the Bergen Social Media Addiction Scale, a six-item psychometric instrument derived from the components model of addiction to assess social media “addiction”, did not form a unitary, but a bidimensional construct in which some components (i.e., salience, tolerance) were not associated with psychopathological symptoms, thus conflating central and peripheral features of addiction. Subsequently, in a recent commentary, Amendola (2023) sought to determine whether our findings were driven by the use of data aggregated from multiple independent datasets, i.e., a decision we transparently acknowledged as a limitation in our original research article. Following their re-analysis, Amendola (2023) claimed to have demonstrated that a unidimensional model best fitted the data. However, they only reported results for a partial set of models relevant to this investigation. In the present reply, through a transparent assessment and reporting of all unidimensional and bidimensional models relevant to this investigation, we show that the bidimensionality of the Bergen Social Media Addiction Scale is, in fact, tenable, robust, and consistent across multiple independent datasets. In line with the growing evidence demonstrating that many sets of criteria involved in operationalizing behavioral addictions pathologize involvement in appetitive behaviors, these results highlight the necessity to renew the conceptualization and assessment of behavioral addictions.

Deconstructing the components model of addiction: an illustration through "addictive" use of social media

The components model of addiction posits that all addictions share six components, namely salience, tolerance, mood modification, relapse, withdrawal, and conflict. This highly influential model has resulted in the development of numerous psychometric instruments that measure addictive behaviors according to these criteria. However, recent research suggests that, in the context of behavioral addictions, certain components constitute peripheral features that do not distinguish non-pathological from pathological behavior. Using “addictive” use of social media as a representative example, we examined this perspective by testing whether these six components actually assess central features of addiction, or whether some of them constitute peripheral features that are not indicative of a disorder. Four independent samples totaling 4,256 participants from the general population completed the Bergen Social Media Addiction Scale, a six-item psychometric instrument derived from the components model of addiction to assess social media “addiction”. By performing structural equation modeling and network analyses, we showed that the six components did not form a unitary construct and, crucially, that some components (i.e., salience, tolerance) were not associated with measures assessing psychopathological symptoms. Taken together, these results suggest that psychometric instruments based on the components model conflate central and peripheral features of addiction when applied to behavioral addictions. This implies that such instruments pathologize involvement in appetitive behaviors. Our findings thus call for renewing the conceptualization and assessment of behavioral addictions.
Extraverts Reap Greater Social Rewards from Passion Because they Express Passion More Frequently and More Diversely
Authors: Krautter Kai , Büchner Anabel , Jachimowicz Jon
Published: November 2023

Passion is stereotypically expressed through animated facial expressions, energetic body movements, varied tone and pitch—and met with interpersonal benefits. However, these capture only a subset of passion expressions that are more common for extraverts. Indeed, in an initial dyadic study of supervisors and their subordinates (N = 330), extraverts expressed their passion more strongly through these stereotypical expressions of passion, and observers perceived extraverts as more passionate than introverts. Across three studies (Ntotal = 1,354), we subsequently developed a more comprehensive passion expressions and behaviors scale (PEBS). Using this measure in a daily diary study (N = 206, k = 1,862), we found that extraverts not only expressed their passion in more stereotypical ways, but through a broader variety of expressions in general. Extraverts are perceived as more passionate because they have a broader behavioral repertoire, express their passion more frequently and diversely, and thereby attain greater interpersonal rewards.
Keeping an eye out for change: Anxiety disrupts adaptive resolution of policy uncertainty
Authors: Lamba Amrita , Frank Michael , FeldmanHall Oriel
Published: November 2023

Background: Human learning unfolds under uncertainty. Uncertainty is heterogeneous with different forms exerting distinct influences on learning. While one can be uncertain about what to do to maximize rewarding outcomes, known as policy uncertainty, one can also be uncertain about general world knowledge, known as epistemic uncertainty. In complex and naturalistic environments such as the social world, adaptive learning may hinge on striking a balance between attending to and resolving each type of uncertainty. Prior work illustrates that people with anxiety—those with increased threat and uncertainty sensitivity—learn less from aversive outcomes, particularly as outcomes become more uncertain. How does a learner adaptively trade-off between attending to these distinct sources of uncertainty to successfully learn about their social environment? Methods: We developed a novel eye-tracking method to capture highly granular estimates of policy and epistemic uncertainty based on gaze patterns and pupil diameter (a physiological estimate of arousal). Results: These empirically derived uncertainty measures reveal that humans (N = 94) flexibly switch between resolving policy and epistemic uncertainty to adaptively learn about which individuals can be trusted and which should be avoided. However, those with increased anxiety (N = 49) do not flexibly switch between resolving policy and epistemic uncertainty, and instead express less uncertainty overall. Conclusions: Combining modeling and eye-tracking techniques, we show that altered learning in people with anxiety emerges from an insensitivity to policy uncertainty and rigid choice policies, leading to maladaptive behaviors with untrustworthy people.
