Agent-based modelling for Urban Analytics: State of the art and challenges
Authors: Malleson Nick , Birkin Mark , Birks Daniel , Ge Jiaqi , Heppenstall Alison , Manley Ed , McCulloch Josie , Ternes Patricia
Published: September 2022

Agent-based modelling (ABM) is a facet of wider Multi-Agent Systems (MAS) research that explores the collective behaviour of individual ‘agents’, and the implications that their behaviour and interactions have for wider systemic behaviour. The method has been shown to hold considerable value in exploring and understanding human societies, but is still largely confined to use in academia. This is particularly evident in the field of Urban Analytics; one that is characterised by the use of new forms of data in combination with computational approaches to gain insight into urban processes. In Urban Analytics, ABM is gaining popularity as a valuable method for understanding the low-level interactions that ultimately drive cities, but as yet is rarely used by stakeholders (planners, governments, etc.) to address real policy problems. This paper presents the state-of-the-art in the application of ABM at the interface of MAS and Urban Analytics by a group of ABM researchers who are affiliated with the Urban Analytics programme of the Alan Turing Institute in London (UK). It addresses issues around modelling behaviour, the use of new forms of data, the calibration of models under high uncertainty, real-time modelling, the use of AI techniques, large-scale models, and the implications for modelling policy. The discussion also contextualises current research in wider debates around Data Science, Artificial Intelligence, and MAS more broadly.

Ultra-short term trading using a neural-network based ensemble of financial technical indicators in a closed world market
Authors: Zafeiriou Theodoros , Kalles Dimitris
Published: September 2022

The proposed paper presents the analysis, design, implementation and evaluation of an ultra-short-term frequency trading system for the foreign exchange market (FOREX), which features all stages of the trading process (Pre-Trade Analysis, Trend Forecasting, Trade Execution). The system uses artificial intelligence techniques in an environment that is constantly changing according to the decisions of the participating trading simulators. Our goal is to simulate the judgment and decision-making of the human expert (technical analyst or broker) in a closed world trading system that constantly adjusts exchange rates. We examine the system in terms of its contribution to how exchange rates are affected in an environment which solely consists of traders, without any exogenous factors, and show that our system can outperform all conventional technical indicators, thereby indicating that it could also play the role of facilitating the stabilization of a market by squeezing out non-intelligent traders. We designed and implemented a self-adjusting trading environment whose exchange rate price is only affected by trading within the environment (closed world assumption). We based our work on a modified series of technical indicator simulators, which are fed to an artificial neural network architecture, to eventually generate the trend forecasting signal and a series of customizable ultra-short term automated trading machines, which perform real-time virtual transactions based on the generated forecasting signals. A comparative analysis of the results is carried out to confirm that the proposed architecture outperforms traders based only on the conventional technical indicators while we also document the behavior of the system towards facilitating the attainment of an equilibrium.
Armature dynamics - an aspect of rail gouging mechanisms in electromagnetic railgun
Authors: Lin Qinghua
Published: September 2022

The purpose of this study is to explore the causes leading to the rail gouging from the perspective of armature dynamics. The axial, lateral motion and rotation equations were derived, and a set of calculations according to the experimental conditions were conducted. The calculated in-bore processes of the armature exhibit apparent non-linear features. Especially with the contact interface of armature being worn rapidly, the armature gradually leans toward one side of the bore, and forms a trend of oblique impact to the rail that may lead to the gouging. This study offered an insight on the transient processes of armature in bore, and helped to better understand the gouging failure mechanism.
Anti-VEGF therapy for diabetic macular edema: up-to-date approaches to the management of patients with high and low baseline functional parameters
Authors:   Ural State Medical University, Yekaterinburg, Russian Federation, Bobykin E.V.
Published: September 2022

Diabetic macular edema (DME) is a serious complication of diabetes mellitus (DM) and a vision-threatening condition which can lead to irreversible blindness. Its prevalence correlates with the number of cases of DM and diabetic retinopathy and demonstrates a stable upward trend. Though modern medicine has made tremendous strides and developed several options for DME treatment which comply with the efficacy and safety criteria from a perspective of evidence-based medicine, DME remains a challenge in the clinical practice. There is no doubt that the key role is played by anti-angiogenic (anti-VEGF) therapy which has become the gold standard treatment for DME and is supported by a strong evidence base. However, some aspects of this method application are understudied. Thus, most of the randomized clinical studies (RCSs) of anti-VEGF therapy included patients with the "averaged" baseline values of visual acuity (within the range of 23–79 letters using ETDRS chart / 0.06–0.7 in decimal system). But in real clinical practice ophthalmologists often observe atypical DME cases where the baseline visual acuity values fall outside the range described in RCSs. The present literature review is aimed at considering tactics of the rational management of patients with atypically low and high baseline visual functions and provides analysis of the recent publications in which the outcomes of anti-VEGF therapy are discussed in the context of this problem. Keywords: macular edema, anti-VEGF therapy, diabetic retinopathy, diabetes, diabetic macular edema, high visual acuity, low visual acuity. For citation: Bobykin E.V.

The results of optimization of biscuit production technology with pumpkin seed additive using electrocontact baking method are presented. The dosage and degree of pumpkin crushing were used as influencing factors in the optimization. The output parameters were the complex index of organolethic properties, volumetric yield of biscuit and specific energy consumption for the process of electric contact baking. Organoleptic characteristics of biscuit were evaluated on a five-point scale by indicators: appearance, consistency, smell, taste. The complex index of organoleptic properties was calculated as the sum of points for individual indicators of organoleptic properties multiplied by the corresponding significance coefficients. The pumpkin dosage 7,25–12,5% and degree of pumpkin crushing 4,4–5,4 mm were found to be optimum, at that the complex index of organoleptic properties of a biscuit would be 90–95 points, specific energy expenses for EС-baking would be not higher than 40–45 W/kg, and the volume yield would reach 400–410%.

Mães narcisistas: a maternidade tóxica e os possíveis danos psico-comportamentais aos filhos
Authors: Abreu Liliane Alcântara de , Melo Natalia Sayuri
Published: September 2022

Este artigo teve como finalidade gerar uma reflexão teórica sobre as mães narcisistas. O tema é um tabu social pautado na figura imagética da genitora santificada, e, portanto, que supostamente não fere seus filhos física, psicológica, emocional e/ou moralmente de forma proposital contínua. Diante dos relatos colhidos – de entrevistas que geram livros e artigos científicos – nos últimos anos por profissionais de saúde mental, está sendo possível fornecer dados de que essas mulheres adoecidas estão produzindo em massa outros indivíduos adoecidos psiquicamente. Desta maneira, as autoras tiveram como questão norteadora: como e por que comportamentos materno-narcisistas podem gerar filhos com adoecimentos psico-comportamentais? Assim, o objetivo geral se fundamentou em detectar como se constrói e se comportam as mães narcisistas, e quais as implicações psicológicas e comportamentais em seus filhos enquanto vítimas diretas dessa relação materna. A hipótese firmou-se no pressuposto de que uma mãe com transtorno de personalidade narcísica pode ter seu comportamento potencializado e/ou reforçado diante do não reconhecimento sociofamiliar de sua demanda. Para tanto, como metodologia a pesquisa se embasou em vários autores de apoio, sendo maior ênfase em Silvia Zornig (2010) e Ana Paula Marson (2008), Sigmund Freud (1980; 2004) Melanie Klein (1966; 1991), Donald Winnicott (1983), Andrea Ferrari, Cesar Picinini e Rita Lopes (2006), Prado (2004), Karyl McBride (2009; 2011), Fernando González (2015), Liliane Abreu (2021). Ademais, a análise de duas entrevistas podem ajudar na compreensão prática desses estudos teóricos. Como resultado e conclusões, compreendeu-se que as mães narcisistas e seus filhos necessitam de atenção psicológica para a quebra e descontinuidade de paradigmas de destruição e manipulação. É necessário de fato refletir e discutir como proteger esses indivíduos afetados e igualmente tratar essas mulheres adoecidas, além da necessidade da quebra de tabus sobre a temática, gerando-se a educação e discussão social. Ademais, que o poder público crie e incentive novas políticas, assim como, refletir-se sobre o processo da maternidade para a mulher contemporânea, desconstruindo a hipotética santidade desse status; revisando inclusive dogmas religiosos edificados junto com o surgimento do patriarcado.

Authors:   Admiral Makarov National University of Shipbuilding, Pohorielova Olena
Published: September 2022

The consequences of the COVID-19 pandemic were the most devastating for food security and nutrition as a result of unprecedented depth and scale of economic downturns caused by pandemic measures. They have caused an economic downturn in 2020 in most countries around the world: per capita incomes have fallen more than ever in recent years.There is not enough scientific work aimed at comprehensively solving the problem in the economic, technological, environmental and social spheres that determine the factors and, accordingly, measures to eliminate or mitigate the effects of economic downturns, increase the resilience of food systems. The aim of this work is to deepen theoretical and methodological approaches and develop policy measures, determine the expected results and systematize implementation tools aimed at addressing food security and malnutrition in a slowdown and economic downturns. The study found that policy measures aimed at addressing food insecurity and malnutrition in the context of slowing economic growth and economic downturns include: policy measures aimed at the main channels of transmission of the impact of slowing economic growth and economic downturns; stimulating complex structural transformations in order to reduce economic vulnerability; cross-sectoral policies aimed at tackling food insecurity and malnutrition, with a special focus on poverty and inequality; making the most of trade for food security and nutrition. The main expected results of such measures are: curbing the rise in food prices or compensating for its consequences; stimulating job creation and increasing incomes; financial feasibility and sustainability of countercyclical policy; developing a balanced policy and ensuring balanced investments in favor of complex transformations. Poverty reduction policy measures are proposed, focusing on each of the main aspects of food security: physical availability of food; economic and physical access to food; food use; stability of the other three dimensions over time.

Published: September 2022

There has been a considerable amount of interest in the study of idioms. English is a language with a vast idiomatic basis, which makes its learning very exciting and intriguing. Idioms, constitute a notoriously difficult area of foreign language learning and teaching. The sheer number of idioms and their high frequency in discourse make idioms an important aspect of vocabulary acquisition and language learning in general. Nowadays language learning is based on the need for interaction with others. This research aims to respond to a need for a proper method of teaching election idioms to High School students. From the growing body of this research, it follows that applying cooperative techniques for teaching election idioms, can improve learning outcomes and can also effectively improve language communication. The results of the pre-test and pro-test show that the cooperative method of teaching election idioms turned out to be more effective than the competitive method in both idioms comprehension and production.
A Comprehensive Review on Lassa Fever in Africa: Epidemiology, Diagnosis, Prevention and Control
Authors: Pal Mahendra , Gedefa Areda Negesa , Girma Lema Adugna
Published: September 2022

Lassa fever is a highly prevalent viral zoonosis that affects two to three million people in West Africa. This is a rodent-borne disease, which has serious consequences on the population and hospital staff in endemic areas. Lassa fever is a public health concern inflicting severe morbidity and important mortality (Case rate (CFR) ≥ 50%), particularly in epidemic cases. The disease has emerged as one of the most prevalent and debilitating viral hemorrhagic fevers and is endemic in the West Africa region. The control and prevention of the regular outbreak of the disease have become a herculean task in the affected; there is inadequate healthcare facility (including laboratory/diagnostic and care centers), poor socioeconomic environment, lack of awareness among the populace, and presence of favorable ecologic niche for the survival and propagation of the natural host and reservoir mouse (Mastomys natalensis) of Lassa virus. It is mainly transmitted by contact with excretions and secretions of infected rats via foods and water as well as exposure to other contaminated items. It is an enveloped, single-stranded (SS) segmented RNA virus with the ability to replicate very rapidly. The virus infects almost every tissue in the human body resulting in multisystem dysfunction. The incubation period is generally between 6 to 21 days resulting in 3 stages of clinical manifestation viz: Acute phase characterized by flu-like, non-specific illness; hemorrhagic phase accompanied with gastrointestinal symptoms and cardiovascular/neurologic complications. Laboratory help is required in order to make an unequivocal diagnosis of the disease. Early diagnosis and prompt therapy are crucial to saving the life of the patient. Currently, there is no clinically certified Lassa fever vaccine thus complicating preventive, and control measures.

The fundamental dimensions of social judgment and social evaluation, called agency and communion, are overarching constructs in many fields of psychology. Agency is related to goal-striving and “getting ahead”, communion is related to forming bonds and “getting along”. These dimensions are used both to interpret behaviors, and to evaluate targets. Bogdan Wojciszke was the first to relate these dimensions to perspective, and to show that the perspective of an actor is more closely related to agency, whereas the perspective of an observer is more closely related to communion. The “Dual Perspective Model” combines the fundamental dimensions of social judgment and evaluation with perspective and leads to a number of far-reaching hypotheses on social interactions. The model has inspired research in diverse areas of psychology, such as evaluation of brands, stereotypes of groups, evaluation of political leaders, gender research, social desirability research, self-evaluation, bodily posture in social interaction, to name just a few. It has been further developed to a broad-ranging theory applicable to many phenomena in (social) psychology. Bogdan Wojciszke lives his ideals and it is a pleasure and an honor to cooperate with him.
PREDICTION OF THE CORRELATION BETWEEN PROBLEM-SOLVING SKILLS AND CONCEPTUAL REASONING IN STOICHIOMETRY
Authors: Kotoka Love , Kriek Jeanne
Published: September 2022

Learners underperform in stoichiometry as they lack conceptual reasoning of the underlying concepts and the ability to solve stoichiometric problems. Therefore, it was necessary to determine if there is a statistical correlation between problem-solving skills and conceptual reasoning in stoichiometry and if so, whether one can significantly predict the other. The theoretical framework is the cognitive load theory (CLT). This theory expects teachers to know where to focus their teaching and how to assess their learners’ work to avoid unnecessary overloading of the working memory, which might affect their performance. The explanatory sequential mixed-method research design was employed with 410 grade 11 Physical Science learners in their intact classes. The participants wrote the learner achievement test (LAT) and responded to a semi-structured interview. The learners’ test scores were then used to run a statistical test. The Pearson correlation and regression showed that the justifications given by learners for choosing correct or incorrect multiple-choice options were not due to chance, and the results of the learner interviews supported the learners’ performance in the test. Moreover, the findings indicated that there was a positive correlation between problem-solving skills and conceptual reasoning where statistically, conceptual reasoning predicted learners’ problem-solving skills using regression analysis.

Published: September 2022

The use of infographics for presenting data in the media and on the Internet has become a widespread phenomenon. This study examines how well undergraduates interpret the mean when presented in infographic, their attitudes towards the misuse of statistics, and their perceptions of their knowledge and use of statistics. The infographic was intended for the general public. The questionnaire was developed in a pilot study and then it was presented to a sample of 270 students from universities in Serbia and the USA. The study showed that STEM undergraduates and those who attended a course in statistics interpreted the infographic better. However, between 46% and 65% of those misinterpreted the infographic which indicates that changes are needed in statistics education to improve statistical literacy. Concerning demographic characteristics, somewhat better results were achieved by the American students, while gender had weak significance. Students whose interpretations were more successful perceived their knowledge and use of statistics as better. An extremely low number of students, 7.5%, disagreed that statistics is often misused, while only 14.2% trusted the research results presented in the media. The results from this study can be useful for curriculum developers, teachers, and researchers on statistical education.

Published: September 2022

It is important for students to understand force concepts because they are central to learning physics and other sciences; however, students find it difficult to understand. There are calls for teachers to tap into their professional knowledge and develop beliefs that help them assist students comprehend the topic. To meet this challenge, teachers’ perceptions of their knowledge base for teaching force concepts should be probed because perceptions act as windows into teachers’ practices. This study, therefore, explored physics teachers’ perceptions of their knowledge base for teaching force concepts. Science teachers’ pedagogical content knowledge (PCK) frameworks were used to develop a questionnaire based on a 5-point Likert scale administered to 100 physical science teachers who were randomly selected from 54 schools in five districts in Lesotho. Data were analysed using descriptive statistics. The results suggest that, even though teachers reported positive views about their knowledge base, there is no correlation between sub-components of curricular knowledge. It is concluded that teachers should build the curricular knowledge by participating in collaborative activities. It is, therefore, recommended that studies that probe teachers’ actual knowledge of PCK constructs are executed, so that appropriate information is available when planning professional development activities targeting teachers’ PCK.

APPLYING FACTOR ANALYSIS FOR ASSESSING KNOWLEDGE STRUCTURE OF STUDENTS IN GRADE 10: THE SUBJECT OF REDOX REACTION
Authors: Tang Wenxiu , Zhu Xintong , Qian Yangyi
Published: September 2022

Redox reaction is an important concept in chemistry, and a well-organized knowledge structure of redox reaction is beneficial for concept learning. This study investigated the knowledge structure regarding redox reaction from 459 Grade 10 students. The pool of 15 redox reaction concepts was developed by content analysis, questionnaire survey, and interview. Six initial competing models with 15 concepts were identified via exploratory factor analysis (EFA) and paper-pencil test. Confirmatory factor analysis (CFA) was conducted to test and modify the six competing models according to the rating data of the students. As a result, six modified models fit the data well. However, the high inter-factor correlations indicate that the two- and three-factor models are the students' knowledge structures of redox reaction. The two-factor model is comprised of two distinct but correlated factors: the process of redox reaction and metrology. The three-factor model is comprised of three factors: the process of redox reaction, reaction ability, and metrology. The finding inflects the abstract relationships between the concepts related to redox reaction in students' minds.

Modeling the Thermal Behavior of the Viscoelastic Properties of Asphalt Concrete
Authors: Sarsam Saad I.
Published: September 2022

The viscoelastic properties of asphalt concrete are susceptible to the variation in the pavement temperature. In the present work, asphalt concrete beam specimens were prepared at optimum binder content and tested under repeated flexural stresses for fatigue life. Three testing temperature were implemented (5, 20, and 30) ℃. The variation in the phase angle, dissipated energy, flexural stiffness, and permanent deformation due to the testing temperatures were monitored and modeled. It was concluded that the viscoelastic properties of asphalt concrete are highly sensitive to the variation in testing temperature. The phase angle and the permanent deformation increases sharply as the testing temperature rises. However, the dissipated energy and the flexural stiffness declines as the testing temperature rise. Mathematical models were obtained which can be implemented in identifying the thermal behavior of the viscoelastic properties of asphalt concrete.
