Urban Community Sustainable Development Patterns under the Influence of COVID-19: A Case Study Based on the Non-Contact Interaction Perspective of Hangzhou City
Authors: Wang Jiwu , Hu Xuewei , Tong Chengyu
Published: March 2021

A community is the basic organization and living unit of a city. During COVID-19, China’s epidemic prevention and isolation measures against COVID-19 based on the community as the basic unit achieved excellent results and strengthened the impact of non-contact interaction activities on the lifestyles of resident communities. We surveyed and interviewed 1610 respondents on how the epidemic changed residents’ lifestyle habits “before, during, and after COVID-19” in 12 communities in Hangzhou, China. Then, we undertook a comparative analysis and found that, under the stimulus of COVID-19, the frequency of residents using non-contact interaction had increased to varying degrees, community lifestyles had undergone significant changes, and the impact of non-contact interaction on community service facilities was complicated. Our conclusions are as following: (1) under COVID-19, the community space had become a composite space—that is, a new type of community space formed by the fusion of community physical space and community virtual space; (2) non-contact interactive activities were the main content in the community composite space, which differently influenced people’s habits of using existing community service facilities; (3) the influence mechanism was manifested in significant differences and spatial scale effects. Therefore, based on the research results, we propose a model for the configuration of service facilities in community composite spaces. It is necessary to build communities into a healthy, safe, and convenient urban space governance unit to ensure the sustainable development of cities.
Twitter’s Messages about Hydrometeorological Events. A Study on the Social Impact of Climate Change
Authors: Oliver Esther , Llasat María Carmen , Llasat-Botija Montserrat , Díez-Palomar Javier
Published: March 2021

This study is based on an interdisciplinary collaboration between scientists from natural and social sciences to create scientific knowledge about how Twitter is valuable to understand the social impact of hydrometeorological events. The capacity of citizens’ reaction through Twitter to environmental issues is widely analyzed in the current scientific literature. Previous scientific works, for example, investigated the role of social media in preventing natural disasters. This study gives scientific evidence on the existence of diversity in the intentionality of Twitters’ messages related to hydrometeorological events. The methodological design is formed by four experiments implemented in different moments of a temporal axis. The social impact on social media methodology (SISM) is implemented as social media analytics. From the findings obtained, it can be observed that there are different forms of intentionality in Twitter’s messages related to hydrometeorological events depending on the contextual circumstances and on the characteristics of Twitter’s users’ profiles (including the geolocation when this information is available). This content is relevant for future works addressed to define social media communication strategies that can promote specific reactions in vulnerable groups in front the climate change.
The EU Health Technology Assessment and the Open Method of Coordination: A Relation with Potential in the Context of Network Governance
Authors: Matei Ani , Dumitru Adrian-Stelian , Antonovici Corina-Georgiana
Published: March 2021

The open method of coordination (OMC)—a tool which was formalized in the early 2000s—has generated the interest of both the researchers and practitioners in the context of the new EU governance. This article is examining the literature of both network governance and OMC, with the focus particularly on one main question: is OMC a useful instrument in health policies in order to achieve concrete results by outlining norms and legislation where EU exercise limited power? Analyzing a field in which the EU competence is limited—given the budgetary implications of medicines reimbursement—from the results of the existing collaboration within EUnetHTA, we will observe the added value in this particular case of the OMC application, and the possible consequences in shaping the supranational competences. Given that the EU, with some exceptions provided by the Treaties, may only exercise actions to support, coordinate or complement the action of the Member States in the health policy, the OMC proves to be a useful tool, both from the perspective of the Member States but especially of the supranational level.
The Impact of Entrepreneurial Orientation on New Product Creativity, Competitive Advantage and New Product Performance in SMEs: The Moderating Role of Corporate Life Cycle
Authors: Yi Ho-Taek , Amenuvor Fortune Edem , Boateng Henry
Published: March 2021

The current study aims to empirically examine the effect of entrepreneurial orientation on new product creativity, competitive advantage, and new product performance. Data are collected from 424 Small and Medium-sized Enterprises (SMEs) in South Korea. The suggested hypotheses are tested through the structural equation modeling technique. The analysis outcome shows that entrepreneurial orientation has a significant positive effect on both new product (NP) novelty and new product meaningfulness. The study further finds that both new product novelty and meaningfulness have significant positive impacts on competitive advantage, respectively, while the latter has a significant positive effect on new product performance. Similarly, the study finds that corporate life cycle significantly moderates the relationship between entrepreneurial orientation and new product meaningfulness. The study offers practical and theoretical insights into understanding entrepreneurship dynamics, new product creativity, and new product performance. The research shows that SME managers must adopt an entrepreneurial orientation at an early stage in the life cycle.
Seamless Integration of Rainfall Spatial Variability and a Conceptual Hydrological Model
Authors: Zhou Yan , Liang Zhongmin , Li Binquan , Huang Yixin , Wang Kai , Hu Yiming
Published: March 2021

Rainfall is an important input to conceptual hydrological models, and its accuracy would have a considerable effect on that of the model simulations. However, traditional conceptual rainfall-runoff models commonly use catchment-average rainfall as inputs without recognizing its spatial variability. To solve this, a seamless integration framework that couples rainfall spatial variability with a conceptual rainfall-runoff model, named the statistical rainfall-runoff (SRR) model, is built in this study. In the SRR model, the exponential difference distribution (EDD) is proposed to describe the spatial variability of rainfall for traditional rain gauging stations. The EDD is then incorporated into the vertically mixed runoff (VMR) model to estimate the statistical runoff component. Then, the stochastic differential equation is adopted to deal with the flow routing under stochastic inflow. To test the performance, the SRR model is then calibrated and validated in a Chinese catchment. The results indicate that the EDD performs well in describing rainfall spatial variability, and that the SRR model is superior to the Xinanjiang model because it provides more accurate mean simulations. The seamless integration framework considering rainfall spatial variability can help build a more reasonable statistical rainfall-runoff model.

Published: March 2021

Social capital is the effective contribution of social groups through providing a context for cooperation, sense of identity, and perception of social norms. Urban parks are important components of cities, helps building the social capital within urban societies. This study examines the social capital of important urban parks of Tehran, Iran, using three main criteria: informal social control, social cohesion, and social leverage. A stratified random sample of 330 users were selected and asked to rank the social capital criteria using a questionnaire involving five-point Likert scale questions. The results show mutual relationship between informal social control and social leverage (r = 0.62, α = 0.00), and also inter-relationship between design indicators and perceived social capital. People from lower age group and higher educational level show highest perception of social capital. Perceptual difference were observed between genders. Women experience higher esthetic perception (α = 0.00), security (α = 0.01), and accessibility (α = 0.03). The study, while proving the relationship between social indicators and design features, and the impact of personal characteristics on the perception of social capital, indicates social inequality in citizens’ equal benefit of social capital. Measures must be taken to increase social capital in society and solve the significant lower perceptions of some social capital indicators among specific groups.
Atomic Cascade Computations
Authors: Fritzsche Stephan , Palmeri Patrick , Schippers Stefan
Published: March 2021

Atomic cascades are ubiquitous in nature and they have been explored within very different scenarios, from precision measurements to the modeling of astrophysical spectra, and up to the radiation damage in biological matter. However, up to the present, a quantitative analysis of these cascades often failed because of their inherent complexity. Apart from utilizing the rotational symmetry of atoms and a proper distinction of different physical schemes, a hierarchy of useful approaches is therefore needed in order to keep cascade computations feasible. We here suggest a classification of atomic cascades and demonstrate how they can be modeled within the framework of the Jena Atomic Calculator. As an example, we shall compute within a configuration-average approach the stepwise decay cascade of atomic magnesium, following a 1s inner-shell ionization, and simulate the corresponding (final) ion distribution. Our classification of physical scenarios (schemes) and the hierarchy of computational approaches are both flexible to further refinements as well as to complex shell structures of the atoms and ions, for which the excitation and decay dynamics need to be modeled in good detail.
Reparametrization Invariance and Some of the Key Properties of Physical Systems
Authors: Gueorguiev Vesselin G. , Maeder Andre
Published: March 2021

In this paper, we argue in favor of first-order homogeneous Lagrangians in the velocities. The relevant form of such Lagrangians is discussed and justified physically and geometrically. Such Lagrangian systems possess Reparametrization Invariance (RI) and explain the observed common Arrow of Time as related to the non-negative mass for physical particles. The extended Hamiltonian formulation, which is generally covariant and applicable to reparametrization-invariant systems, is emphasized. The connection between the explicit form of the extended Hamiltonian H and the meaning of the process parameter λ is illustrated. The corresponding extended Hamiltonian H defines the classical phase space-time of the system via the Hamiltonian constraint H=0 and guarantees that the Classical Hamiltonian H corresponds to p0—the energy of the particle when the coordinate time parametrization is chosen. The Schrödinger’s equation and the principle of superposition of quantum states emerge naturally. A connection is demonstrated between the positivity of the energy E=cp0>0 and the normalizability of the wave function by using the extended Hamiltonian that is relevant for the proper-time parametrization.
Natural Lagrangians
Authors: Tamm Martin
Published: March 2021

In this paper, a probabilistic approach is used to derive a kind of abstract candidate for a natural Lagrangian in general relativity. The methods are very general, and the result is in a certain sense unique. However, to turn this abstract Lagrangian into an ordinary one, expressible in terms of the Riemann tensor, is so far an open problem. Some possible cosmological consequences are discussed.
Testing Quantum Mechanics with an Ultra-Cold Particle Trap
Authors: Riggs Peter J.
Published: March 2021

It is possible to empirically discriminate between the predictions of orthodox (i.e., Copenhagen) quantum theory and the de Broglie−Bohm theory of quantum mechanics. A practical experiment is proposed in which a single, laser-cooled ion inside an ultra-cold particle trap is either found to be near the trap’s walls or not. Detections of the former kind would support the prediction of orthodox quantum theory and of the latter kind would support the de Broglie−Bohm theory. The outcome of this experiment would show which theory gives the more correct description and, consequently, would have far-reaching implications for our understanding of quantum mechanics.
A Comparison of Porphyrin Photosensitizers in Photodynamic Inactivation of RNA and DNA Bacteriophages
Authors: Heffron Joe , Bork Matthew , Mayer Brooke K. , Skwor Troy
Published: March 2021

Effective broad-spectrum antiviral treatments are in dire need as disinfectants and therapeutic alternatives. One such method of disinfection is photodynamic inactivation, which involves the production of reactive oxygen species from dissolved oxygen in response to light-stimulated photosensitizers. This study evaluated the efficacy of functionalized porphyrin compounds for photodynamic inactivation of bacteriophages as human virus surrogates. A blue-light light emitting diode (LED) lamp was used to activate porphyrin compounds in aqueous solution (phosphate buffer). The DNA bacteriophages ΦX174 and P22 were more resistant to porphyrin TMPyP photodynamic inactivation than RNA bacteriophage fr, with increasing rates of inactivation in the order: ΦX174 << P22 << fr. Bacteriophage ΦX174 was therefore considered a resistant virus suitable for the evaluation of three additional porphyrins. These porphyrins were synthesized from TMPyP by inclusion of a central palladium ion (PdT4) and/or the addition of a hydrophobic C14 chain (PdC14 or C14). While the inactivation rate of bacteriophage ΦX174 via TMPyP was similar to previous reports of resistant viruses, ΦX174 inactivation increased by a factor of approximately 2.5 using the metalloporphyrins PdT4 and PdC14. The order of porphyrin effectiveness was TMPyP < C14 < PdT4 < PdC14, indicating that both Pd2+ ligation and C14 functionalization aided virus inactivation.

Published: March 2021

Pruritus is a common symptom of several skin diseases, both inflammatory and neoplastic. Pruritus might have a tremendous impact on patients’ quality of life and strongly interfere with sleep, social, and work activities. We review the role of type-2 inflammation and immunity in the pathogenesis of chronic pruritic conditions of the skin. Type 2 cytokines, including IL-4, IL-13, thymic stromal lymphopoietin, periostin, IL-31, IL-25, and IL-33 are released by mast cells, innate lymphoid cells 2, keratinocytes, and type 2 T lymphocytes, and are master regulators of chronic itch. These cytokines might act as direct pruritogen on primary sensory neurons (pruriceptors) or alter the sensitivity to other itch mediators Type 2 inflammation- and immunity-dominated skin diseases, including atopic dermatitis, prurigo nodularis, bullous pemphigoid, scabies, parasitic diseases, urticaria, and Sézary syndrome are indeed conditions associated with most severe pruritus. In contrast, in other skin diseases, such as scleroderma, lupus erythematosus, hidradenitis suppurativa, and acne, type 2 inflammation is less represented, and pruritus is milder or variable. Th2 inflammation and immunity evolved to protect against parasites, and thus, the scratching response evoked by pruritus might have developed to alert about the presence and to remove parasites from the skin surface.

Published: March 2021

People living with HIV are a high-risk population concerning the coronavirus 19 (COVID-19) infection, with a poorer prognosis. It is important to achieve high COVID-19 vaccination coverage rates in this group as soon as possible. This project used self-reporting to assess vaccine hesitancy and acceptance among people living with HIV towards the novel COVID-19 vaccine. Sixty-eight (28.7%) participants among the 237 declared their hesitancy to be vaccinated against COVID-19. Participants who expressed concerns about their health (p < 0.001), the requirement of mandatory COVID-19 vaccination (p = 0.017), and their chronic disease status (p = 0.026) were independently associated with the acceptance of vaccination. Conversely, participants presenting general vaccine refusal (p < 0.001), concerns about the serious side effects of COVID-19 vaccines (p < 0.001), and those already thinking having an immune status to COVID-19 (p = 0.008) were independently associated with COVID-19 vaccine hesitancy. Our results suggest that vaccine strategy would be more successful in France with a communication strategy emphasizing the collective benefits of herd immunity in the population living with HIV and reassuring patients with chronic diseases about the safety of the proposed vaccines.
Single and Competitive Adsorption Behaviors of Cu2+, Pb2+ and Zn2+ on the Biochar and Magnetic Biochar of Pomelo Peel in Aqueous Solution
Authors: Wu Qianlan , Dong Shuzhen , Wang Lijun , Li Xiaoyun
Published: March 2021

As an environment-friendly material, biochar has been used to remove heavy metals from wastewater, and the development of cost-effective biochar has been an emerging trend. However, limited studies consider the competitive adsorption of co-existing metals and the separation efficiency of absorbent and solution after adsorption. In this study, pomelo peel was used to prepare biochar (BC) and magnetic biochar (MBC) at different temperatures. Then, the physicochemical properties of the biochars were characterized and the adsorption characteristics of Cu2+, Pb2+, and Zn2+ on the biochars in single, binary, and ternary metal systems were investigated. The results showed that both pyrolysis temperature and magnetization could affect the adsorption capacity of biochar. The adsorption kinetic and thermodynamic processes could be well described by the pseudo-second-order kinetic model and Langmuir model. The adsorption isotherm types of Pb2+ and Zn2+ changed in the binary metal condition. The competitive adsorption order of three heavy metal ions in ternary metal adsorption was Pb2+ > Cu2+ > Zn2+. The MBC of 500 °C showed a good adsorption capacity to Pb2+ in the co-existing environment, and the maximum adsorption capacity was 48.74 mmol g−1. This study also provided technical support for the utilization of pomelo peel and the engineering application of biochar.

Authors: Soares Rogério Barbosa , da Silva Samiria Maria Oliveira , Souza Filho Francisco de Assis de , Paiva Witalo de Lima
Published: March 2021

This work aims to identify the key sectors of the economic structure, considering their water flows, and estimate each sector’s impact. The goal is to highlight systemic characteristics in the regional economy, establish water use priorities, and assess water security. Based on a regional input-output matrix, we use the following methodologies: the Rasmussen and Hirschman indices for the ‘forward and backward linkages’; simple multipliers of production, job, and income; and the elasticity of water consumption to final water demand. Thirty-two economic sectors and household consumption are analysed. From the elasticity of final water demand, we find that both trade and household consumption put more pressure on water consumption. Furthermore, a joint analysis of the applied methodologies shows that: (a) the trade sector is more relevant for the linkage of water flows, (b) the agriculture sector has the highest direct water consumption, and (c) the public administration sector has the highest intermediate water consumption.
Assessment of the Impacts of Land Use Change on Non-Point Source Loading under Future Climate Scenarios Using the SWAT Model
Authors: Feng Mao , Shen Zhenyao
Published: March 2021

The Miyun Reservoir is an important source of surface drinking water in Beijing. Due to climate change and human activities, the inflow of Miyun Reservoir watershed (MRW) has been continuously reduced in the past 30 years, which has seriously affected the safety of Beijing’s water supply. Therefore, this study aimed to assess the mitigation measures based on the quantification of the integrated impacts of climate and land use change in MRW. The non-point source (NPS) model (soil and water assessment tool, SWAT) was used for the development of future climate scenarios which were derived from two regional climate models (RCMs) under two representative concentration pathways (RCPs). Three land use scenarios were generated by the land use model (conversion of land-use and its effects (CLUE-S)): (1) historical trend scenario, (2) ecological protection without consideration of spatial configuration scenario and (3) ecological protection scenario. Moreover, the reduction of sediment and nutrients under three future land use patterns in future climate scenarios was evaluated. The results showed that an appropriate land use change project led to the desired reduction effect on sediment and nutrients output under future climate scenarios. The average reduction rates of sediment, total nitrogen and total phosphorus were 11.4%, 6.3% and 7.4%, respectively. The ecological protection scenario considering spatial configuration showed the best reduction effect on sediment, total nitrogen and total phosphorus. Therefore, the addition of region-specific preference variables as part of land use change provides better pollutant control effects. Overall, this research provides technical support to protect the safety of Beijing’s drinking water and future management of non-point source pollution in MRW.

Published: March 2021

Search and development of non-waste and environmental technology solutions of bioconversion of manure and waste water, providing extraction of valuable nutrients additional feed for livestock and poultry, as well as allowing to reduce (or eliminate) the discharge of wastewater into the environment is an important direction of development of modern science, which is of crucial economic and social importance. The purpose of the research was to improve the biotechnology of wastewater treatment from livestock and poultry farms. The problem of protection of water objects from contamination by surface wastewater from the catchment area of livestock and poultry farms has been considered by the authors of the article. A new methodological approach to protecting the environment from waste pollution consists in minimizing wastewater discharges to theoretically achievable limits; using drinkingquality water exclusively to ensure technical and sanitary conditions for the normal functioning of livestock farms; full utilization of off -balance water directly at the farms. The implementation of the strategic goal should be translated into a waste-free water supply for all enterprises in the industry. No waste water discharge – there is no problem of land and water contamination. A new technology has been developed for the treatment of manure-containing and litter-containing waste water. The researches has been confi rmed the possibility of using modern biotechnologies for the treatment of contaminated wastewater from livestock and poultry farms. The use of an accumulative phytofi lter is an eff ective method of protecting water ecosystems from contamination by surface wastewater from catchment areas of livestock and poultry farms. The proposed construction provides not only environmental friendliness of the technology, but also naturally fi ts into the landscape of the area.
Autumn preparation of bee families for wintering for the raising of extra early bee queens under the conditions of the Republic of Uzbekistan
Authors: Khudaiberdiev A. A. , Mannapov A. G.
Published: March 2021

The potential honey supply available in the Republic of Uzbekistan can have up to 2 million bee families. For the development of the beekeeping industry in Uzbekistan, it is necessary to create a purebred population of Apis mellifera carpatica, based on the reproduction of early purebred queen bees. In addition to protein fi llers and mineral complexes, probiotics were used as part of stimulating feed additives for autumn and spring stimulation of egg production of queen bees. However, in our opinion it is better to add prebiotics to the composition of feed additives, which are available in the composition of infant formula used for baby food. It has been established by studies that stimulating feed additives with protein fi llers, combined with cobalt sulfate and a mixture of “Nanny 2 with prebiotic” positively infl uence on the growth, development and economically useful traits of maternal, paternal and queen-rearing colonies in preparation for winter. It has been proved that a high rate of growth of the brood being grown is carried out when giving honey satiety in the composite form with CoSO4 + “Nanny 2 with prebiotic” mixture. In comparison with the background level, this parameter reaches its maximum by the third accounting, increasing in maternal families by 2,41 times, in paternal families – 2,61 times, in queen-rearing colonies – 2,61 times. It has been found that the Carpathian queen bees showed their high genetic capabilities for egg production during the autumn increase in the strength of families with the 3rd and 4th variants of feed additives until the end of the experiment. The maximum rate of egg laying females recorded in the 4th group, exceeded the same level of the 1st group of the parent families by 1,44 times, 2nd group – 1,24 times 3rd group by 1,14 times. An adequate pattern has been registered for paternal and queen-rearing colonies. Stimulating feed additives in particular, the use in group 4 of honey additive in a composite form with CoSO4 + mixture of “Nanny 2 with prebiotic” has a prolonging eff ect, both on the egg-laying ability of queen bees, and on brood feeding, which increases the strength of bee families. By the beginning of winter, this force was 15,4 and 16,0 seams of bees between two combs in the maternal families, 15,5 and 15,8 seams of bees between two combs in the paternal families, and 15,8 and 16,0 seam of bees between two combs in the queen-rearing colonies, respectively. This indicates that a complete generation of autumn bees will be obtained, which will not only successfully overwinter, but will also be actively used in the breeding of extra early queen bees in the new season.

Published: March 2021

Бородаті іриси зарекомендували себе як чудове рішення для створення ландшафтних груп у садовому дизайні. Захворювання на листкову плямистість ірисів, спричинене Cladosporium iridis, завдає шкоди сортам бородатих ірисів, що вирощуються у колекції ботанічного саду ХНПУ імені Г.С. Сковороди. В наслідок інфікування знижується декоративність рослин, а при сильному ураженні – квітування не відбувається, це робить вирощування ірисів недоцільним, оскільки головною цінністю є пишне квітування. З метою пошуку найбільш стійких сортів та груп сортів ірисів до захворювання на листкову плямистість, нами протягом весняно-літнього сезону 2020 р. велися спостереження за садовими культурами Iris × hybrida «Cloud Ballet», «Copatonic», «French Horn», «Green and Gifted», «Jazzed Up», «Latin Lark», «Pink Tafeta», «Salsa Rio», «Smiling Faces», «Supreme Sultan», «Pumping Orion», «El Torytto», а також Iris pumila «Скіф» та «Політ Фантазії». Досліджені сорти належали до чотирьох сортових груп (Високі бородаті мініатюри, Стандартні високі бородаті, Мініатюрні бородаті карлики та Стандартні бородаті карлики). Ступінь ураженості рослин хворобою вимірювалась за двома показниками: поширенням, яке відображає частку уражених рослин певного сорту, та розвитком хвороби, яке показує відсоток уражених частин окремої рослини. За результатами дослідження з’ясовано, що збільшення ураження спостерігалось протягом усього вегетаційного періоду, без виходу на плато. Максимальний ріст ураження спостерігався у травні-червні в подальшому інфікування зростало на 9-10% в порівнянні з попереднім місяцем і припинялось лише з відмиранням надземної частини. Серед досліджених сортів за вразливістю до захворювання виділяються два класи: більш вразливі до кладоспоріозної листкової плямистості (Високі бородаті мініатюри та Стандартні високі бородаті) та менш вразливі до неї (Мініатюрні бородаті карлики та Стандартні бородаті карлики). В кожній садовій групі було виявлено сорти, з найменшим проявами ураження I. pumila – «Скіф», I. × hybrida – «Pumping Orion», «Copatonic», «Salsa Rio».
participación al derecho a la participación de niñas, niños y adolescentes en las escuelas y la educación en México:
Authors: Zurita Rivera Ursula Del Carmen
Published: March 2021

En este artículo teórico se analiza la participación de niñas, niños y adolescentes en las escuelas y la educación en la reforma educativa de Enrique Peña Nieto impulsada en México entre 2012 y 2018. Este propósito es relevante porque durante el siglo XX, se observa una tensión entre la aceptación formal de la participación tutelada del alumnado en cuestiones concretas, bajo ciertas modalidades, en determinados niveles educativos; y, por otra, el rechazo y obstaculización de esa participación a cargo de autoridades educativas y escolares. La reforma no promovió la participación del estudiantado mexicano y la tensión continuó, aunque parecía que cambiaría con la Ley General de Derechos de Niñas, Niños y Adolescentes del 2014 porque estipuló por primera vez el derecho a la participación de estas poblaciones en las escuelas y otros ámbitos. Pero la concepción del derecho a la participación siguió reproduciendo la visión tutelada que ha estado presente desde años atrás en instrumentos jurídicos nacionales, como la Ley Orgánica de la Educación Pública de 1942 e internacionales, como la Convención sobre los Derechos del Niño de 1989. Aquí se examinan los desafíos que enfrenta el sistema educativo del tramo obligatorio para que el alumnado sea reconocido como actor con agencia y como productor de conocimiento. Así, se expone un breve recuento del enfoque de las Voces del Alumnado para identificar el alcance de las modificaciones emprendidas por la reforma educativa sobre la participación del estudiantado y, finalmente, entender las diferencias entre la participación y el derecho a la participación en las escuelas.

COMPREHENDING THE CITY... BOOK REVIEW: T. A. VLASOVA, K. N. OBUKHOV «IZHEVSK 2020: EXPERIENCE OF SOCIOLOGICAL RESEARCH OF THE SYMBOLIC SPACE OF THE CITY»
Authors: MOISEEVA Darya V. , DULINA Nadezhda V.
Published: March 2021

The article discusses the key points of the sociological study of the symbolic space of the city of Izhevsk, performed by T. A. Vlasova and K. N. Obukhov in 2019-2020 and the results, which the researchers have designed in the form of a monograph. When studying the problems of urban development, T. A. Vlasova and K. N. Obukhov managed to get away from the dry bureaucratic language inherent in official documents and reports, and create a «living» picture of the modern Russian city of Izhevsk, reflecting the opinion of the expert community living in this city and ordinary citizens. At the same time, the book contains a lot of «fairy tales», a thoughtful acquaintance with which can be useful both for scientists specializing in the study of the city and urbanism, and for practitioners implementing projects of urban improvement and the formation of the city's brand.

Authors: BAGDASARIYAN Nadezhda G. , MELNIKOVA Natalia E. , BALUEVA Tatyana V.
Published: March 2021

The article examines the phenomenon of online education, which is very actively spreading in foreign and domestic education systems, but requiring monitoring of this process. The problems of online education are analyzed according to the assessments of domestic and foreign authors, including the materials of annual conferences held by the Sloan Consortium Corporation (now Online Learning Consortium (OLC)). The data of a sociological study of the motivation and readiness of online education actors at a regional university using the methodology of nonparametric statistics are presented. The cluster analysis, carried out by the K-means method, made it possible to obtain an empirical typology of tutors and students of Dubna State University and identify target groups among university members of faculty as online course developers and among university students as consumers of an online educational product. A comprehensive analysis of the theoretical and empirical blocks made it possible to identify trends in the development of online education, problem areas associated not only with the economic component, but also with motivational reinforcement, which can be considered among the factors of managerial decision-making by the university administration.

The project consists of the design and construction of a biodigester that allows the generation of methane gas for heating and cooking food in domestic stoves. The Biodigestor will have as byproduct Biol, from leached organic matter, this byproduct can be used as fertilizer in gardens or domestic crops. The monitored variables of the Biodigestor use a data acquisition card to obtain the level of Ph, biol, temperature, humidity and pressure during the methane generation process, as well as the quantity and quality of methane gas produced. This project has been developed in several stages, design, prototype scale tests, connection of sensors and tests that allow to define reference data and data during methane production. A design has been achieved that allows simultaneous production in three biodigestors, this proposal will allow through a specific protocol, the continuity in obtaining the gas can be maintained with the possibility of emptying, cleaning and replacing organic matter without stopping the methane production process

Objectives: The objective of the work was to identify a natural alternative that allows to obtain more efficient productive parameters and that in turn the immune system of the birds is more resistant to pathogens. The administration of seaweed polysaccharides has been shown to promote greater resistance to individuals under stress conditions, suggesting an immunostimulatory effect. Methodology: 582 male chickens of the Cobb genetic line were used, with one day of births which were distributed in 2 treatments with 3 repetitions of 97 birds: control treatment and treatment with polysaccharides. The polysaccharides used were of the Olmix © brand and were used at a dose of 45 g per 500 L of water on days 9, 11, 12, 19, 21, 22, 34, 36, and 37 of life. Productive parameters and cellular response were determined, which was performed by smears stained with the hayem-turk technique to later perform the count in the neubauer chamber. Samples for leukocyte and lymphocyte count were performed on days 9, 12, 19, 22, 34 and 37. Contribution: The use of polysaccharides can favor the weight gain of the broiler.
Communitarian Theory and Andalusian Imagery in Carmel Bird’s Fiction. An Interview
Authors: Rodríguez-Salas Gerardo
Published: March 2021

Australian writer Carmel Bird writes fiction that, while being highly individual and varied, settles within the Australian traditions of both Peter Carey’s fabulism and Thea Astley’s humane wit. As William H. Wilde, Joy Hooton and Barry Andrews state (1994), Bird is a “witty writer with a wide but always highly original tonal range”, who “raises what is often potentially sinister or horrific to something approaching comedy. Disease, deaths and violence are staples in her fictional world, which has similarities with Barbara Hanrahan’s Gothic sensuality and feminist irony, although Bird’s deadpan humour is a distinctive, determining element”. The present interview focuses on an unexplored area in Bird—Andalusia, Spain—which, paradoxically, becomes the backcloth of some of her fiction—like the recent Child of the Twilight (2010)—and a prolific source of inspiration. The following pages explore Bird’s Andalusian/Spanish visions as regards nationalistic, religious, and cultural constructions. To that end, the theoretical communitarian discussion of figures like Ernest Gellner, Ferdinand Tönnies, Benedict Anderson, Jean-Luc Nancy and Maurice Blanchot will prove useful in the structural framework of this interview. Bird herself clarifies that her contribution is not offered from an academic perspective; she speaks about herself as a writer largely unaffected by academic bias. However, communitarian theorisation will prove useful in clarifying her depiction of nationalistic and religious values, while, in the process, she sheds some light on the slippery concept of “Australian writing” and the construction of Spanish cultural values from the perspective of an Australian writer. This interview offers a fresh rendition marked by the humorous, spontaneous and truthful tone that characterises Bird’s fiction.
