A Quantitative Approach of Subway Station Passengers’ Heterogeneity of Decision Preference Considering Personality Traits during Emergency Evacuation
Authors: Wang Heng , Jiang Zehao , Xu Tiandong , Li Feng
Published: November 2021

Subway station emergencies are gradually increasing in China. The aim of this research is to study the effects of “Dist”, “Pedestrian flow” and “Crowd density” on the heterogeneity of passengers’ decision-making preference and explore the relationship between heterogeneity and personality. Firstly, a questionnaire of 20 emergency evacuation scenarios, that includes the Eysenck Personality Questionnaire, is designed. Secondly, the heterogeneity of passengers’ decision preference is quantified by the random parameter logit model. Finally, personality traits and influencing factors are used as abscissa and ordinate respectively, to study the relationship between personality traits and preference heterogeneity. The results show that the coefficients of “Dist”, “Pedestrian flow” and “Crowd density” are −0.101, 0.236 and −0.442 respectively, which are statistically significant. The proportion of extroverted passengers of the exit is 9% higher than that of introverted passengers when “Pedestrian flow” of the exit is greater than the average value, while the proportion of introverted passengers is 7% higher than that of extroverted passengers when “Crowd density” is smaller than the average value. The conclusion is that the three influence factors are random variables, and “Dist” shows the lowest level of heterogeneity. Extroverted passengers are more likely to follow a large crowd for evacuation, but introverted passengers are more likely to avoid crowded exits.

The study analyses the benefits and challenges emerging from students’ interactions with community, teachers, and other students in the place-based education program Roots and Shoots, in the Slovak Republic. The study is based on qualitative analyses of data obtained from eight teachers and 56 students interviewed in eight focus groups, and on quantitative data obtained from 53 students. Both the students and the teachers perceived the Roots and Shoots program as highly successful. The implementation of the program was challenged by the necessity of dealing with different levels of the students’ participation in decision-making, tensions between the involved and uninvolved students, and the complex nature of local sustainability issues. This study discusses the importance of engaging students in the participative process of solving real-world issues, reflecting the challenges of this educational approach.
Multiple Analytical Models to Evaluate the Impact of Carbon Nanotubes on the Electrical Resistivity and Compressive Strength of the Cement Paste
Authors: Piro Nzar Shakr , Mohammed Ahmed Salih , Hamad Samir Mustafa
Published: November 2021

Cement paste is the most common construction material being used in the construction industry. Nanomaterials are the hottest topic worldwide, which affect the mechanical properties of construction materials such as cement paste. Cement pastes containing carbon nanotubes (CNTs) are piezoresistive intelligent materials. The electrical resistivity of cementitious composites varies with the stress conditions under static and dynamic loads as carbon nanotubes are added to the cement paste. In cement paste, electrical resistivity is one of the most critical criteria for structural health control. Therefore, it is essential to develop a reliable mathematical model for predicting electrical resistivity. In this study, four different models—including the nonlinear regression model (NLR), linear regression model (LR), multilinear regression model (MLR), and artificial neural network model (ANN)—were proposed to predict the electrical resistivity of cement paste modified with carbon nanotube. Furthermore, the correlation between the compressive strength of cement paste and the electrical resistivity model has also been proposed in this study and compared with models in the literature. In this respect, 116 data points were gathered and examined to develop the models, and 56 data points were collected for the proposed correlation model. Most critical parameters influencing the electrical resistivity of cement paste were considered during the modeling process—i.e., water to cement ratio ranged from 0.2 to 0.485, carbon nanotube percentage varied from 0 to 1.5%, and curing time ranged from 1 to 180 days. The electrical resistivity of cement paste with a very large number ranging from 0.798–1252.23 Ω.m was reported in this study. Furthermore, various statistical assessments such as coefficient of determination (R2), mean absolute error (MAE), root mean square error (RMSE), scatter index (SI), and OBJ were used to investigate the performance of different models. Based on statistical assessments—such as SI, OBJ, and R2—the output results concluded that the artificial neural network ANN model performed better at predicting electrical resistivity for cement paste than the LR, NLR, and MLR models. In addition, the proposed correlation model gives better performance based on R2, RMSE, MAE, and SI for predicting compressive strength as a function of electrical resistivity compared to the models proposed in the literature.
Potential for Food Self-Sufficiency Improvements through Indoor and Vertical Farming in the Gulf Cooperation Council: Challenges and Opportunities from the Case of Kuwait
Authors: Abdullah Meshal J. , Zhang Zhengyang , Matsubae Kazuyo
Published: November 2021

The countries of the Gulf Cooperation Council (GCC) are considered food secure due to their ability to import sufficient food to meet their populations’ demand, despite considerable environmental limitations to conventional agriculture. However, over-reliance on externally produced food leaves these countries vulnerable to food shortages during crises that disrupt international production and shipping. Advanced Controlled Environment Agriculture technology has the potential to improve food self-sufficiency by multiplying vegetable crop yields while optimizing efficiency of agricultural inputs and minimizing land requirements. This paper demonstrates how approximately 15 km2 of indoor farms or less than 0.1 km2 of vertical farms could reduce or eliminate the need to import six important vegetable crops in the State of Kuwait. If properly contextualized and supported by clear legislation and well-managed regulatory bodies, indoor agriculture initiatives may provide a pathway for GCC countries to reduce their dependence on imported foods and increase resilience to food supply disruption during disasters or conflict. This case study contextualizes the need for improved food self-sufficiency in light of vulnerabilities from regional and global threats, illuminates unique challenges faced by GCC countries considering adoption of the proposed technologies, and summarizes opportunities inherent in the current legal and policy framework.
Research on Unrealistic Optimism among HoReCa Workers as a Possible Future Hotspot of Infections

Published: November 2021

As we are facing a new surge of the highly infectious delta variant of COVID-19, there is an urgent need for research to reduce the harm before this next wave hits. In the present paper, we present data that is alarming. We have found that HoReCa (hotels, restaurants, and catering services) workers, who are highly exposed to many new social interactions in close contact, present an unrealistic optimism (UO) bias: they perceive themselves as less at risk to this virus in comparison to others. From the literature, we already know that individuals holding this view are less involved in preventive actions and present more risky behaviors. In the face of the delta variant, this leads to the conclusion that restaurants will be new hot spots. What is more, we found that these unrealistic expectations are more pervasive: workers of the restaurant industry estimate low chances of bankruptcy, which may lead to unrealistic salary expectations, leading owners to a new upcoming wave of crisis: COVID-19 and bankruptcy—both of which may be caused by their workers.

Published: November 2021

The Taiwanese government has decided to reduce the use of disposable plastics in response to the European Union’s announcement of the Circular Economy Action Plan. With the circular economy becoming a sustainable development trend, consumers have become the latter and the environment’s lifeblood. There has been a wave of unpacked stores around the world in recent years, encouraging consumers to reduce the use of plastics and bring their own bags or containers when shopping, thereby reducing the waste of resources. This research adopted qualitative and quantitative research methods to verify the model of involvement degree and perceived value on consumers’ purchase intentions in unpacked stores through expert interviews and structural equations and extract the key factors for promoting unpacked stores. The research results show that the three dimensions of involvement degree will indirectly affect consumers’ purchase intentions through the four dimensions of perceived value. Perceived value plays a mediating role between the involvement degree and purchase intention. Unpacked stores can be used to promote industry characteristics and image, and unpacked consumption thinking can be advanced through the Internet, education, or lectures based on community development. In this way, unpacked stores can be instilled in people’s psychological value.

Published: November 2021

Currently, offshore areas have become the hotspot of global gas and oil production. They have significant reserves and production potential. Offshore platforms are energy-intensive facilities. Most of them are equipped with gas turbine engines. Many technologies are used to improve their thermal efficiency. Thermochemical recuperation is investigated in this paper. Much previous research has been restricted to analyzing of the thermodynamic potential of the chemically recuperated gas turbine cycle. However, little work has discussed the operation issues of this cycle. The analysis of actual fuel gases for the steam reforming process taking into account the actual load of gas turbines, the impact of steam reforming on the Wobbe index, and the impact of a steam-fuel reforming process on the carbon dioxide emissions is the novelty of this study. The obtained simulation results showed that gas turbine engine efficiency improved by 8.1 to 9.35% at 100% load, and carbon dioxide emissions decreased by 10% compared to a conventional cycle. A decrease in load leads to a deterioration in the energy and environmental efficiency of chemically recuperated gas turbines.

Published: November 2021

We discuss an investigation of the dark matter decay modes of the neutron, proposed by Fornal and Grinstein (2018–2020), Berezhiani (2017, 2018) and Ivanov et al. (2018) for solution of the neutron lifetime anomaly problem, through the analysis of the electrodisintegration of the deuteron d into dark matter fermions χ and protons p close to threshold. We calculate the triple-differential cross section for the reaction e−+d→χ+p+e− and propose to search for such a dark matter channel in coincidence experiments on the electrodisintegration of the deuteron e−+d→n+p+e− into neutrons n and protons close to threshold with outgoing electrons, protons, and neutrons in coincidence. An absence of neutron signals should testify to a detection of dark matter fermions.
Asymptotic Results for Multinomial Models
Authors: Akoto Isaac , Mexia João T. , Marques Filipe J.
Published: November 2021

In this work, we derived new asymptotic results for multinomial models. To obtain these results, we started by studying limit distributions in models with a compact parameter space. This restriction holds since the key parameter whose components are the probabilities of the possible outcomes have non-negative components that add up to 1. Based on these results, we obtained confidence ellipsoids and simultaneous confidence intervals for models with normal limit distributions. We then studied the covariance matrices of the limit normal distributions for the multinomial models. This was a transition between the previous general results and on the inference for multinomial models in which we considered the chi-square tests, confidence regions and non-linear statistics—namely log-linear models with two numerical applications to those models. Namely, our approach overcame the hierarchical restrictions assumed to analyse the multidimensional contingency table.

Systemic envenomation by Crotalus durissus terrificus (South American rattlesnake) can cause coagulopathy, rabdomyolysis, acute kidney injury, and peripheral neuromuscular blockade, the latter resulting in flaccid paralysis. Previous studies have shown that plant products such as tannic acid and theaflavin can protect against the neuromuscular blockade caused by C. d. terrificus venom in vitro. In this work, we used mouse-isolated phrenic nerve-diaphragm preparations to examine the ability of caffeic acid, chlorogenic acid, and quercetin to protect against C. d. terrificus venom-induced neuromuscular blockade in vitro. In addition, the ability of tannic acid to protect against the systemic effects of severe envenomation was assessed in rats. Preincubation of venom with caffeic acid (0.5 mg/mL), chlorogenic acid (1 mg/mL), or quercetin (0.5 mg/mL) failed to protect against venom (10 μg/mL)-induced neuromuscular blockade. In rats, venom (6 mg kg−1, i.p.) caused death in ~8 h, which was prevented by preincubation of venom with tannic acid or the administration of antivenom 2 h post-venom, whereas tannic acid given 2 h post-venom prolonged survival (~18.5 h) but did not prevent death. Tannic acid (in preincubation protocols or given 2 h post-venom) had a variable effect on blood creatinine and urea and blood/urine protein levels and prevented venom-induced leukocytosis. Tannic acid attenuated the histological lesions associated with renal damage in a manner similar to antivenom. The protective effect of tannic acid appeared to be mediated by interaction with venom proteins, as assessed by SDS-PAGE. These findings suggest that tannic acid could be a potentially useful ancillary treatment for envenomation by C. d. terrificus.

African swine fever virus (ASFV) causes acute hemorrhagic fever in domestic pigs and wild boars, resulting in incalculable economic losses to the pig industry. As the mechanism of viral infection is not clear, protective antigens have not been discovered or identified. In this study, we determined that the p30, pp62, p72, and CD2v proteins were all involved in the T cell immune response of live pigs infected with ASFV, among which p72 and pp62 proteins were the strongest. Panoramic scanning was performed on T cell epitopes of the p72 protein, and three high-frequency positive epitopes were selected to construct a swine leukocyte antigen (SLA)-tetramer, and ASFV-specific T cells were detected. Subsequently, the specific T cell and humoral immune responses of ASFV-infected pigs and surviving pigs were compared. The results demonstrate that the specific T cellular immunity responses gradually increased during the infection and were higher than that in the surviving pigs in the late stages of infection. The same trend was observed in specific humoral immune responses, which were highest in surviving pigs. In general, our study provides key information for the exploration of ASFV-specific immune responses and the development of an ASFV vaccine.

Longitudinal mapping of antibody-based SARS-CoV-2 immunity is critical for public health control of the pandemic and vaccine development. We performed a longitudinal analysis of the antibody-based immune response in a cohort of 100 COVID-19 individuals who were infected during the first wave of infection in northern Italy. The SARS-CoV-2 humoral response was tested using the COVID-SeroIndex, Kantaro Quantitative SARS-CoV-2 IgG Antibody RUO Kit (R&D Systems, Bio-Techne, Minneapolis, USA) and pseudotype-based neutralizing antibody assay. Using sequential serum samples collected from 100 COVID-19 recovered individuals from northern Italy—mostly with mild disease—at 2 and 10 months after their first positive PCR test, we show that 93% of them seroconverted at 2 months, with a geometric mean (GeoMean) half-maximal neutralization titer (NT50) of 387.9. Among the 35 unvaccinated subjects retested at 10 months, 7 resulted seronegative, with an 80% drop in seropositivity, while 28 showed decreased anti-receptor binding domain (RBD) and anti-spike (S) IgG titers, with a GeoMean NT50 neutralization titer dropping to 163.5. As an NT50 > 100 is known to confer protection from SARS-CoV-2 re-infection, our data show that the neutralizing activity elicited by the natural infection has lasted for at least 10 months in a large fraction of subjects.

Published: November 2021

Special attention should be paid to the planning of human resources in health care, since this problem in the healthcare sector is quite urgent at present (there is a gradual decrease in nursing and medical personnel). The purpose of this study is to determine the role of staffing in the context of protection of reproductive health of the younger generation in the Russian Federation. The main analytical base of the research was statistical data and materials of domestic and foreign literary sources, periodicals, including various electronic resources. Research methods included: statistical method, study and generalization of experience, content analysis. In the course of the study, the issues of staffing with specialists in the conditions of protecting the reproductive health of the younger generation in the Russian Federation were analyzed, taking into account comparable indicators in the general structure of medical and mid-level medical personnel of various specialties; the experience of specialists in obstetrics and urological and andrological service has been studied, taking into account the resource capabilities of medical organizations. One of the main directions in the study of reproductive health is timely prevention, especially on the basis of antenatal clinics or health centers, medical prevention centers. Thus, we can conclude that staffing in the framework of the protection of adolescents’ reproductive health plays an important role, while in order to improve the situation with the participation of the state, it is necessary to revise and work out new programs for the development of human resources potential in health care, as well as to create adequate conditions for their implementation at various hierarchical levels of management, including the introduction of additional measures for social support and advanced training of specialists in this profile.

Published: November 2021

For higher education institution, one of the most important tasks is to form its own competitive advantages, search, interest and retain consumers, because the main goal of HEIs is its long-term successful activity based on the quality of educational services. On the one hand, the transition to market relations has contributed to the emergence of nongovernmental (private) higher education institutions, increasing the number of participants and a variety of educational programs. On the other hand, the demand for higher education services has risen sharply. As a result, competition in the education market has intensified, which has prompted higher education institutions to increasingly use marketing to adapt their activities to market conditions. The complexity of positioning a higher education institution is determined by the diversity of consumers of educational services, including employers as representatives of the labor market. Therefore, the task of the educational organization is to find a unique position that, being significant for all or most consumers, would allow the higher education institution to differentiate itself from competitors. The article investigates the directions of positioning of higher education institutions. It is established that as a result of increasing competition in the market of educational services, there is a need for higher education institutions to increasingly use marketing to adapt their activities to market conditions. The essence of the definition of "positioning" from the point of view of different authors is considered, the concept of positioning through the prism of higher education institutions is singled out.

There have been analyzed the possibilities of using different classes of models to support decision-making in terms of certainty in the management of ecological and economic systems, including optimization and functional ecological and economic models, which are closely related and in some sense are equivalent models. Such models include those describing ecological and economic interaction by means of the problems of mathematical and linear programming. The specificity of these models is that their optimal values are functions of МАТЕМАТИЧНІ МЕТОДИ, МОДЕЛ І ТА ІНФОРМАЦІЙНІ ТЕХНОЛОГІ Ї В ЕКОНОМ ІЦІ 104 Випуск І (81), 2021 model parameters that reflect both economic and environmental characteristics of the studied processes, so this type of model is an implicit reflection of the set of allowable values of their parameters in the set of optimal values of objective functions. These reflections are numerical functions of the dependence of optimal values on model parameters, which in the case of models of linear optimization can be constructed in an explicit analytical form, and their properties are close to the so-called neoclassical functions used in the theory of consumption, production and so on. The paper proposes optimization of ecological and economic models for maximization of output and profit from it. The target functions of these models are the functions of output and profit respectively, and the admissible set of used production resources are formed by the restrictions on economic and environmental resources of the manufacturer. The vectors of the maximum possible volumes of these resources are used to build, on the basis of these models, ecological and economic functions of optimal output and profit, that are the functional models of decision-making in ecological economy. These functions, like other models in this class, are an effective tool to support decision-making in practice as they are a more convenient tool for those responsible for making decisions and implementing them. The algorithm for constructing such functions and their peculiarity for practical application is substantiated, which lies in the fact that they model strict control over the manufacturer's compliance with environmental standards, motivates the manufacturer to adhere to environmental production standards and relevant environmental legislation. As decision-making models, the proposed models of ecological and economic functions are of great practical importance for the development of environmental standards and technological policy of the country or its regions.

En este trabajo se diseña una secuencia de tareas de alta demanda cognitiva basadas en la sucesión ‘look and say’ y se implementa en un grupo de secundaria con especial interés por las matemáticas durante una sesión del Taller de Talento Matemático en la Universidad de Zaragoza. La metodología es exploratoria y descriptiva con análisis mixto de datos cualitativos. Los alumnos participantes resolvieron las tareas con un alto grado de éxito y surgieron bastantes respuestas de gran riqueza conceptual. Estas tareas pueden ser útiles para trabajar aspectos transversales del currículo e identificar alumnos con altas capacidades matemáticas.

Published: November 2021

Изложена методика прогнозирования распространения нефтепродуктов группы BTEX (бензол, толуол, этилбензол, ксилолы) в подземных водах на основе гидрохимического моделирования с учетом изменения окислительно-восстановительных и кислотно-щелочных свойств раствора в процессе биодеградации нефтепродуктов. Представлена геохимическая модель биологического разложения нефтепродуктов комплекса BTEX на основе модифицированной кинетики Моно с учетом реакций между акцепторами, продуктами реакции биодеградации и неорганическими компонентами раствора. Приведены примеры геохимического моделирования, демонстрирующие важность учета процессов, связанных с изменением гидрогеохимической обстановки в подземных водах при разложении углеводородов. Разработанная модель может быть использована для выполнения геохимических прогнозов распространения легких нефтепродуктов в подземных водах, проведения работ в рамках оценки воздействия на природную среду, разработки систем инженерной защиты подземных вод от загрязнения нефтепродуктами.

A method for predicting the spread of BTEX group oil products (benzene, toluene, ethylbenzene, xylenes) in groundwater based on hydrochemical modeling with account of changes in the redox, acidity or alkalinity of the solution during the biodegradation of oil products is stated. A geochemical model of the biological decomposition of oil products of BTEX group based on modified Mono kinetics with account of the reactions between acceptors, biodegradation products and inorganic components of the solution is presented. Examples of geochemical modeling are given that demonstrate the importance of taking into account the processes associated with the changes in the hydrogeochemical environment in groundwater during the decomposition of hydrocarbons. The developed model can be used to carry out geochemical predictions of the spread of light-end oil products in groundwater, to carry out works within the framework of estimating the environmental impact, and to develop systems for engineering protection of groundwater from oil pollution.

Authors: Malysh E. V.
Published: November 2021

Aim. The presented study aims to propose ways of developing new competitive advantages with allowance for the requirements of environmental sustainability by systematizing theoretical approaches and analyzing the institutional aspects of land rent.

Tasks. The authors show systemic trends in the formation of environmental rents in the agricultural sector and propose a plan for developing competitive advantages in the context of environmental sustainability challenges by using the systemic effects of various forms of environmental land rent.

Methods. This study uses the methods of comparison, systems analysis, systematization of information, and the monographic method.

Results. A generalized scheme for developing competitive advantages in the context of new environmental sustainability challenges and requirements based on the use of the systemic effects of various forms of environmental land rent is presented.

Conclusions. The greening of agro-industrial production is a prerequisite for achieving environmental, energy, food, and climate security. Companies that manage to effectively combine sustainability and strategy create value by changing their business model to form a new environmental and social resource associated with factors contributing to business advantage and value creation. The rent system in the agricultural sector expands the concept of land rent. The localization of agricultural rents makes it possible to use systemic effects for increased environmental and social impact, enhancing advantages for the business.
A Trump-adminisztráció Afganisztán-politikája
Authors: Nagy Zsolt
Published: November 2021

Donald Trump elnökségének Afganisztán-politikája két szakaszra osztható. Az elsőt a 2017 augusztusában bejelentett stratégia határozta meg, amely lényegét illetően a korábbi elnöki ciklusok egyes elemeinek az újracsomagolása volt. A fő hangsúly a katonai erőfeszítés fokozásán volt a tálibok ellenállásának megtörése érdekében. Amikorez a stratégia nem hozta meg a várt eredményt, 2018 nyarától Washington – hosszú évek után ismét – tárgyalásokba bocsátkozott a tálibokkal, jelentős engedményeket téve korábbi álláspontjához képest. Ez végül 2020 februárjában az Amerikai Egyesült Államok és a tálibok közötti megállapodáshoz vezetett, megnyitva az utat az afgánközi tárgyalásoknak is. A Trump-adminisztráció egy törékeny békefolyamatot és minimálisra csökkentett amerikai jelenlétet hagyott örökségül Afganisztánban. Az amerikai csapatok végleges kivonásáról és a háború befejezéséről viszont már Trump utóda, Joe Biden döntött.

Einstein en de kunst van... Managen zonder macht: Zeven alternatieven
Authors: de Graaf Anne , Kunst Klaas
Published: November 2021

Einstein Voor de auteurs staat Albert Einstein voor: nieuwsgierig, consistent, integer, gewetensvol, aandachtig en altijd persoonlijk. De onderzoeker, die vooral denkt in hypotheses, die hij aandachtig toetst door het stellen van vragen. Vragen en doorvragen, niet ophouden nieuwsgierig te zijn: een belangrijk kenmerk voor leiders en managers, die beogen verbetering te brengen in vaak complexe situaties. ... en de kunst van het zeilen In 2005 verscheen Einstein en de kunst van het zeilen, een zoektocht naar de nieuwe rol van de leidinggevende. Een lees- en werkboek over leiderschap en management, dat uitnodigt mee te zoeken naar de nieuwe rol van de leider. Het verzoek van veel gebruikers om ‘meer’, krijgt gehoor in de reeks Einstein en de kunst van.... Boeken met dezelfde ambitie, die de structuur, het karakter en de speelsheid van het basisboek naadloos volgen. Managen zonder macht De boodschap van dit boek is niet dat managen met macht (control of many by a few) per definitie overal en altijd fout zou zijn. Managen zonder macht (the capacity to produce change) blijkt echter een serieuze optie, die de moeite waard is om te onderzoeken. In die zin is dit boek een (onder)zoektocht, die de auteurs graag samen met hun lezers willen aangaan. Dit boek biedt een aantal theoretische kaders uit de Transactionele Analyse (Eric Berne), Group Relations Theory (Wilfred Bion) en de Systeem- en Communicatietheorie (Paul Watzlawick). Het is echter vooral een handreiking bij de zoektocht naar en de worsteling met de rol van leidinggevende in een snel veranderende omgeving.
