Authors: Aquino A.M. , Morales D.B.
Published: December 2020

The packaging industry is now geared towards natural and biodegradable raw materials to
reduce packaging wastes. In this study, purple yam (Dioscorea alata L.) peels were
utilized to extract anthocyanins to be incorporated as a pH indicator in cassava starch
films. The extract was analyzed for its total monomeric anthocyanin content (TMAC)
using the pH differential method, and antioxidant activity using the DPPH assay. Results
showed that the extract contains 155 mg/L cyanidin-3-glucoside and high antioxidant
activity of 78.84%. Using the casting technique, thin films were made from cassava starch
and glycerol, with varying amounts of the extract (0, 10, 20, 30 and 50%). The films were
characterized by their color properties, water activity (Aw) and tensile strength (TS).
Results showed decreasing values of L*
, a*
, b*
as the concentration of the extract
increased. No significant difference (p>0.05) was observed in the Aw and TS of the
control film and the colored films. There was no trend observed in the Aw and TS of the
films. The film with 30% extract recorded the lowest Aw (0.214) while the film with 40%
extract recorded the highest tensile strength (0.706). The film with the highest TS was
subjected to color response analysis by immersing the films in buffer solutions at different
pH levels (pH 1.0-12.0) for 10 mins, and the time when the first color change was
observed was recorded. The fastest responses were observed at the extreme pH levels (pH
1.0–2.0; 10.0–12.0). This study was able to conclude that purple yam peel extract has the
potential as a pH indicator in cassava starch films for application as intelligent packaging.

Цель работы. В статье представлен анализ региональной маршрутной сети на примере аэропорта г. Бордо (Франция) двух крупнейших европейских бюджетных авиакомпаний «easyJet» и «Ryanair». Методы и методология проведения работы. На основе представленных данных крупнейших авиакомпаний Европы выделена роль и влияние бюджетных авиакомпаний на рынок пассажирских авиаперевозок. На основе анализа маршрутной сети бюджетных авиакомпаний выделена их особая роль на рынке региональных пассажирских перевозок малой и средней дальности. Результаты. На основании проведенного исследования определена роль бюджетных авиакомпаний на рынке региональных пассажирских авиаперевозок малой и средней дальности в структуре рынка пассажирских авиаперевозок. Бизнес-модель бюджетных авиакомпаний рассчитана на минимизацию уровня производственных затрат, таким образом, бюджетные авиакомпании пользуются услугами региональных аэропортов. Региональные аэропорты заинтересованы в привлечении новых клиентов и увеличении общего пассажиропотока. Бюджетные авиакомпании получают от региональных аэропортов существенные льготы на обслуживание воздушных судов, а также более низкие аэропортовые сборы для пассажиров. В результате бюджетные авиакомпании сокращают производственные затраты и имеют возможности для развития региональной маршрутной сети малой и средней дальности. На примере аэропорта г. Бордо графически отображены данные о выполняемых маршрутах двух крупнейших бюджетных авиакомпаний «easyJet» и «Ryanair». Представленные данные свидетельствуют о том, что развитие бюджетных авиакомпаний происходит, в первую очередь, благодаря развитию региональной маршрутной сети, что позволяет расширять рынок пассажирских авиаперевозок. Область применения результатов. Результаты проведенного исследования могут быть применимы для разработки системы развития бюджетных авиакомпаний в России, в первую очередь, на рынке региональных перевозок малой и средней дальности. Выводы. Рынок бюджетных авиаперевозок в России имеет высокие перспективы развития. Российская бюджетная авиакомпания «Победа» имеет высокую динамику роста и развития. При этом доля иностранных бюджетных авиакомпаний на рынке авиаперевозок России продолжает оставаться крайне низкой. В условиях макроэкономической нестабильности спрос на доступные региональные авиаперевозки будет возрастать, следовательно, бюджетные авиакомпании имеют все основания для увеличения доли рынка.

Published: December 2020

The aim of the study was to evaluate the rate of polymerization of tubulin into microtubules and determine the level of colchicine binding (colchicine-binding activity of tubulin) in the prefrontal cortex in schizophrenia, vascular dementia (VD) and control. Colchicine-binding activity of tubulin was determined by Sherlinе in tubulin-enriched extracts of proteins from the samples. Measurement of light scattering during the polymerization of the tubulin was carried out using the nephelometric method at a wavelength of 450-550 nm. There was a significant decrease in colchicine-binding activity and the rate of tubulin polymerization in the prefrontal cortex in both diseases, and in VD to a greater extent than in schizophrenia. The obtained results suggest that not only in Alzheimer's disease, but also in other mental diseases such as schizophrenia and VD, there is a decrease in the level of tubulin in the prefrontal cortex of the brain, although to a lesser extent than in Alzheimer's disease, and consequently the amount of microtubules.

Paradise Lost: Explaining Populism as a Response to the Fragmentary Nature of Time, Space, and the Rapid Pace of Technological Advancement
Authors: Vrhoci Dora
Published: December 2020

Contemporary societies and technologies are evolving at an ever-swifter pace. Advances in the field of Augmented Reality (AR) and in Computer Science at large have led to games that let us immerse ourselves in worlds stuffed with zombies, robots, or pokemon critters. Globalization is making the world ever more interconnected, and the development of diverse social media platforms is changing the way people engage with politics and culture in their daily lives. Time and space have arguably never been more liquid, fragmentary, and compressed. Against this host of developments, Postmodern ideas on the fragmentation of time and space,the rupture in personal and national identity narratives, as well as the concept of «utopia,» can provide theoretical tools, shedding light on how various agents react to the rapid pace of technological change (such as Information and Communications Technology (ICT) and digitalization), and subsequent alterations in Man’s perception of time and space. This paper reconstructs the key tenets of Postmodern thinking on cultural phenomena, showing how the changing experience of time and space (induced by globalization, and technological advances) bear on the recent successes of populist parties in Europe and beyond. Furthermore, the paper places populists’ narrative of and nostalgic mourning for an ideal past in a longer continuum of utopian and dystopian thinking. This is then interpreted as an attempt to build a vision of a homeostatic space that, once conceptualized as a rhetorical tool, serves to forgebonds among ‘(good) people

Published: December 2020

The Men for Equality movement [El movimiento de hombres por la igualdad - HPLI], although a fairly recent phenomenon, already has a forty year track record in Valencia. The movement has had its high and low points. After the trail blazed by protagonists in Valencian society, a period of consolidation followed in which those who came after them kept the movement going. A qualitative study carried out by the Department of Sociology and Social Anthropology records the impressions of those men who kept the movement alive between 1975 and 2018 despite the odds at the outset. These voices are analysed within frameworks for interpreting movements. As a social movement, Men for Equality developed new codes of behaviour and meaning. The resultsreveal the need – now greater than ever – of a paradigm shift in masculinity in Spain and Valencia.

Internet celebrities, as a group of stars spawned by the market economy and The Internet, reveal both the state of Internet culture and the transformation of mass media in China. The bodies and pictures of these ‘celebs’, while unique, also take on a cultural symbolism. The 4.0 Revolution is the carrier of social practices and kinds of interaction in which the social media play a very special role. In this paper we will focus on the intersections and ruptures between the bodyindividual, body-subjective and body-social (Scribano, 2007) of Chinese Internet celebrities and the articulations and links between body-image and their body-in-movement. With the introduction ofChinese social media platforms such as WeChat (微信), Sina Weibo (新浪微博), Douyin, we try to trace links between the sociability, experiences and social sensibilities of the Internet celebrities and their influence on Society 4.0. This paper: (a) looks at the Chinese social media as a virtual platform for the Internet celebrities; (b) delves into the images and practices of the Internet celebrities; (c) highlights the link between body, sensation and perception regarding social celebrities; (d) shows the kinds of sociability and social sensibilities exhibited by celebrities in China’s Society 4.0. home foreclosure) in several Catalan municipalities.

Woman, manage your life! The Life-Work Balance Discourse in Popular Management Literature Aimed at Women*
Authors: Medina-Vicent Maria
Published: December 2020

Management posts have traditionally been held by men. Consequently, the business management normative model has dictated the rules women should follow. Among other reasons, this is why the issue of work-life balance has been sidelined in popular management literature. In keeping with these male-dictated rules, it was always blithely assumed that the manager's role was exclusively linked with his public presence — in other words, family and care issues were left out of the equation. However, as more and more women have become managers, new issues have shaped the management agenda. In this paper, we study how the issue of work-life balance has been incorporated in popular management literature for women. We are particularly interested in identifying whether the discourse on women’s presence in management enshrines: (1) a transformative, egalitarian vision (requiring policies fostering work-life balance), or (2) a view that sees women’s traditional household roles as something belonging to the private sphere, leaving them disadvantagedand bereft of support as they pursue their management careers.

En el físic i la imatge que projecten aquestes celebritats, si bé són úniques, hi ha implícit un simbolisme cultural. La revolució 4.0 ens porta noves pràctiques socials i maneres d'interactuar amb les xarxes socials com a protagonistes. En aquest article investigarem les interseccions i ruptures entre cos-individu, cossubjectiu i cos-social (Scribano, 2007) de les estreles d’internet xineses, i les articulacions i relacions entre el cos-imatge i el seu cos-en-moviment. Analitzem plataformes de xarxes socials xineses com WeChat (微信), Sina Weibo (新浪微博) o Douyin per rastrejar vincles entre la sociabilitat, les experiències i les sensibilitats socials de les celebritats d'internet i la seua influènciaen la societat 4.0 xinesa.Aquest article (a) examina les xarxes socials xineses com a plataforma virtual de les estreles d’internet; (b) aprofundeix en les imatges i pràctiques de les estreles d’internet; (c) subratlla la relació entre el cos, la sensació i la percepció quant a lescelebritats socials; (d) mostra els tipus de sociabilitat i sensibilitats socials exhibides per les celebritats en la societat 4.0.
La cultura en nom del poble? Cap a una tipologia del populisme i la cultura
Authors: Jansma Judith
Published: December 2020

Durant les últimes dècades, el populisme ha estat àmpliament estudiat, tot i que des d’una perspectiva majoritàriament política. Les contribucions en aquest camp se centren sobretot en l’anàlisi del populisme com a fenomen sociopolític en el context històric i global. Una altra àrea d’estudi es refereix al suport popular dels partits populistes. Aquesta qüestió, a més de ser de la màxima actualitat, revela les imperfeccions de la democràcia liberal.Tot i que s’ha dedicat un gran esforç acadèmic a proporcionar una definició de populisme i les raons de l’èxit que té, encara queda per aclarir en quines creences culturals es basen els seus arguments populistes que empren una falsadicotomia entre «nosaltres» i «ells». Per aquesta raó, després de fer un breu resum del treball acadèmic que s’ha fet fins avui en les disciplines de la ciència política i els estudis culturals, intentarem presentar una tipologia de la culturai el populisme, que ens ajudarà a entendre per què els diferents aspectes de la cultura (com ara la cultura popular, les imatges culturals i les obres literàries) són de capital importància en la construcció populista del «nosaltres» i l'«ells».La tipologia es basa en els exemples de França i Holanda (dos països amb importants partits de dreta populista) per a distingir entre sociofacts, mentifacts i artifacts (Huxley) i l’ús que tenen en l’apropiació dels actors populistes. L’última categoria es compon d’allò que anomenarem «autors orgànics» i «autors apropiats», en la terminologia emprada per Gramsci. La diferència entre les dues, com es demostrarà, rau en la identificació de l’autor amb un tipus determinatd’idees, així com en l’articulació d’aquestes.
Corruption, Șmecherie, and Siliconization
Authors: McElroy Erin Mariel Brownstein
Published: December 2020

This article explores socialist and postsocialist technoculture in postsocialist Romania, focusing upon both retrospective and speculative accounts of what did, and what could have, transpired beyond the purview of the state and of capitalism. Upon a backdrop of postsocialist Siliconization and Western anticorruption politics, it looks to queer, corrupt, and deviant technological practices that pervert normative and Western accounts of socialism and its transition. In particular, this article sifts through speculative and retrospective accounts of hackers, computer cloners, and political artists and organizers, many of whom narrate technocultural practices of șmecherie—a Romanian word with Romani roots inferring cunningness and cleverness. These narrations, imaginations, and speculations, I suggest, corrupt postsocialist Siliconization and anticorruption politics through practices of cloning, play, excess, and kinship.
Non-Hermitian Hamiltonian Treatment of Stark Effect in Quantum Mechanics
Authors: Hallford Randal , Sharma Preet
Published: December 2020

The Non-Hermitian aspect of Quantum Mechanics has been of great interest recently. There have been numerous studies on non-Hermitian Hamiltonians written for natural processes. Some studies have even expressed the hydrogen atom in a non-Hermitian basis. In this paper the principles of non-Hermitian quantum mechanics is applied to both the time independent perturbation theory and to the time dependant theory to calculate the Stark effect. The principles of spherical harmonics has also been used to describe the development in the non-Hermitian case. Finally, the non-Hermitian aspect has been introduced to the well known Stark effect in quantum mechanics to find a condition in which the Stark effect will still be true even if a non-Hermitian Hamiltonian is used. This study completes the understanding at a fundamental level to understand the well known Stark effect. Doi: 10.28991/esj-2020-01242 Full Text: PDF
Current and Historical Application of Knowledge Management in Economy
Authors: Tomé Eduardo
Published: December 2020

Objectives: The paper tries to analyse the current and historical application of Knowledge Management in the Portuguese Economy, particularly since the democratic revolution of 1974. Methods/Analysis: Study is based in theories about the impacts of knowledge in countries at a micro and a macro scale. A three levels mode is used, related to context (namely 1) Historical background; 2) basic economic and social data: 3) broad vocational education and training (VET) systems; 4) institutional actors; 5) political context),  intervention (namely 1) basic legislative documents, 2) guidelines on eligibility, 3) programs, 4) evaluation procedures) and outcomes (namely 1) stocks, investment, and outcomes; 2) price, quantity, supply, demand, equilibria; 3) needs).  Data used are statistical published data and other published documents. Findings: The context changed for the better, because after 1974 the country rulers installed a regime in which knowledge was not seen like a luxury but as a basic need; the change in context was also helped by the adhesion to the EU, which in turn led to massive interventions supported by funds like the ESF and the Regional fund; as a result outcomes are finally seen, as the increase in supply and demand of knowledge and also in the income and employability of the Portuguese attests. Novelty/Improvement These findings are important because they depict the slow but sure transformation of Portugal into a Knowledge Economy. Should be complemented by a more detailed analysis, with a larger group of researchers. Doi: 10.28991/esj-2020-01245 Full Text: PDF
Analysis of Host Resources Utilization by OpenStack in Ubuntu Environment
Authors: Pericherla Suryateja Satya
Published: December 2020

Cloud computing is one of the frontier technologies, which over the last decade has gained a widespread commercial and educational user base. OpenStack is one of the popular open source cloud management platforms for establishing a private or public Infrastructure-as-a-Service (IAAS) cloud. Although OpenStack started with very few core modules, it now houses nearly 38 modules and is quite complex. Such a complex software bundle is bound to have an impact on the underlying hardware utilization of the host system. The objective is to monitor the usage of system resources by OpenStack on commodity hardware. This paper analyzes the effect of OpenStack on the host machine's hardware. An extensive empirical evaluation has been done on different types of hardware, at different virtualization levels and with different flavours of operating systems comparing the CPU utilization, memory consumption, disk I/O, network, and I/O requests. OpenStack was deployed using Devstack on a single node. The novel aspect of this work is monitoring the resource usage by OpenStack without creating virtual machines on commodity hardware. From the analysis of data, it is observed that standalone machine with Ubuntu server operating system is the least effected by OpenStack and thereby has more available resources for computation of user workloads. Doi: 10.28991/esj-2020-01246 Full Text: PDF
Estimation of Residential Property Market Price: Comparison of Artificial Neural Networks and Hedonic Pricing Model
Authors: Štubňová Michaela , Urbaníková Marta , Hudáková Jarmila , Papcunová Viera
Published: December 2020

The correct real estate property price estimation is significant not only in the real estate market but also in the banking sector for collateral loans and the insurance sector for property insurance. The paper focuses on both traditional and advanced methods for real estate property valuation. Attention is paid to the analysis of the accuracy of valuation models. From traditional methods, a regression model is used for residential property price estimation, which represents the hedonic approach. Modern advanced valuation methods are represented by the artificial neural network, which is one of the soft computing techniques. The results of both methods in residential property market price estimation are compared. The analysis is performed using data on residential properties sold on the real estate market in the city of Nitra in the Slovak Republic. To estimate the residential property prices, artificial neural networks trained with the Levenberg-Marquart learning algorithm, the Bayesian Regularization learning algorithm, and the Scaled Conjugate Gradient learning algorithm, and the regression pricing model are used. Among the constructed neural networks, the best results are achieved with networks trained with the Regularization learning algorithm with two hidden layers. Its performance is compared with the performance of the regression pricing model, and it can state that artificial neural networks can considerably improve prediction accuracy in the estimation of residential property market price. Doi: 10.28991/esj-2020-01250 Full Text: PDF
