Actividad eléctrica no lineal de las ondas beta cerebrales durante una prueba de atención sostenida
Authors: Maureira Cid Fernando , Díaz-Muñoz Hernán
Published: June 2021

Introducción: la atención es un proceso cerebral donde se focaliza selectivamente uno de los estímulos del entorno y desecha la información restante, siendo una función relevante para relacionarse en forma eficiente con el entorno. Objetivo: estudiar el comportamiento no-lineal de la oscilación beta (13-30 Hz), evaluado a través del balance caos/orden cerebral (exponente de Hurst), durante la ejecución de una prueba de atención sostenida en estudiantes universitarios. Método: la muestra estuvo constituida por 13 estudiantes universitarios varones. Para el registro electroencefalográfico se utilizó el dispositivo cerebro-interfaz Emotiv Epoc® Research Edition utilizando los registros del lóbulo frontal, temporal y occipital. Se analizó el rango de frecuencia de 13 a 30 Hz (onda beta). Para la evaluación de la atención sostenida se utilizó la prueba de Toulouse-Piéron. Resultados: durante los dos primeros minutos de la prueba los valores de los exponentes de Hurst presentan asimetrías en la región prefrontal y occipital en tres sujetos con mayor tendencia al caos en la región izquierda y en la región temporal en ocho estudiantes con mayor tendencia al caos en la región derecha. Esta situación se modifica a medida que avanzan los minutos de la prueba. Conclusión: Los exponentes de Hurst tienden a disminuir durante la resolución de la prueba de atención, esto permite mayor flexibilidad de procesamiento durante la prueba. Existe mayor tendencia al caos en la región temporal derecha que se relaciona con el reconocimiento de tonos y de contenido fundamental en pruebas de atención sostenida.
Energías renovables no convencionales para satisfacer la demanda energética: análisis de tendencias entre 1990 y 2018
Authors: Romero Pereira María Carolina , Higinio Pulido Ana María
Published: June 2021

Con el propósito de analizar el resultado de casi tres décadas de enfuerzos por migrar a un suministro energético basado en energías renovables (ERs), específicamente en ERs no convencionales (ERNCs), se analizaron datos sobre producción y consumo energético en las regiones definidas por la Agencia Internacional de Energía (IEA), entre 1990 y 2018.

Se encontró que aunque la producción global de ERs casi se duplicó en las últimas tres décadas, las fuentes de energía producida no han cambiado sustancialmente, ya que el porcentaje de energía producida con combustibles fósiles (CFs) se mantiene en el 81%. Al revisar el consumo energético final, se encuentra un avance de 0,5 puntos porcentuales, entre 1990 y 2018, con una demanda global abastecida con ERs que pasó del 15,4% a 15,9%. Para las ERNCs, este valor pasó del 0,1% al 1,9%.

En 2018, Islandia era la economía con mayor porcentaje del consumo energético final proveniente de ERNCs, en donde cerca del 42% provenía de energía geotérmica. Las ERNCs en ninguna otra economía tuvieron este alcance, siendo Dinamarca el país que ocupó el segundo lugar, con un 10%.

En general, las economías con matrices energéticas de menor escala logran un mayor porcentaje de participación de ERNCs en el consumo energético final.  Las ERs generadas con biomasa y energía hidráulica históricamente han tenido un mayor alcance en las matrices energéticas de mayor escala, aunque el alto impacto ambiental asociado a estas formas de generación de energía debe ser considerado, si el propósito es lograr un menor costo ambiental asociado al desarrollo económico y poblacional.

An Overview of Interdisciplinary Exploration of Writing
Authors: Mahanta Sonali
Published: June 2021

Writing is an age-old tradition and thus the availability of theoretical explanations are also numerous. Both academically and non-academically, this skill has always been dealt with several approaches for exploring its various facets. Writing is the most preferred skill for determining literacy along with reading skill. The thematic and theoretical attempts have covered numerous discourse and can be categorised as cognitive, mix-cognitive and non-cognitive[1] approaches. This research paper attempts at making a theoretical evaluation and exploration of the available approaches to writing. The exploration of writing[2] as a discourse of knowledge reveals its interdisciplinary nature. Mix-cognitive signifies such perspectives that recognizes cognitive as well as non-cognitive explanations to writing. Writing and composition has been used interchangeably in this article.
Queer Ecologies – Research Paper [May 2021]: The Portrayal of Queerness in Malayalam Films
Authors: Mammen Ashika Ann
Published: June 2021

The term “Queer” mainly refers to anything which pertains to sexual behavior, identity or personality which does not conform to the conventional social or heterosexual norms, and assumptions. Being queer was and still is seen as an abnormality by multitudes in the society. Although it has been more than two years since the decriminalization of homosexuality in India, there are still plenty of societies which ill-treat, ostracize and look down upon the LGBTQ communities. The state of Kerala, having the highest literacy rate amongst all the other states in India, also happens to be one of the states which still look at queerness as an illness and an abnormality, which has to be dealt with and ‘cured’ through counseling and medication. However, in the midst of all these preconceived notions and social injustices against the LGBTQ communities, ‘Films’ stand as a strong medium of communication and a voice for the LGBTQ communities who are seen as ‘nobodies’ in our society. Films that have a theme of queerness tend to stand out from the cliché themes such as [heterosexual] love, patriarchy, hegemony, crime, and so on. The focus of this research paper is narrowed down to Malayalam films which stand as a solid foundation in order to show the portrayal of queerness and this is incorporated through a research question. Malayalam films aren’t just a source of entertainment, but it is also an emotion and an important part of life to the people of Kerala. The portrayal of queerness in Malayalam films have taken a bold stand, with exemplary performances in films like Randu Penkuttikal (1978), Deshadanakkili Karayarilla (1986), Chanthupottu (2005), Njaan Marykutty (2018), Moothon (2019) and more. This research paper throws light upon the various ways in which Malayalam films depict the theme of queerness, which is further carried out by a strong message with regard to the ill-treatment of the LGBTQ communities, the harsh realities and injustices faced by these sexual minorities who live a life filled with difficulties and hardships as they struggle to get a well paid job in a our stereotypical society, that labels them off as a bunch of “misfits.”
Toni Morrosion – The Vitalist: Bio Versus Necro Centricities
Authors: J. Kennedy
Published: June 2021

Toni Morrison, as many think, is a feminist writer or an African-American writer and so on. When we read her novels, she does not confine herself with feminism, or Africanism, or Americanism, or a writer for pleasure reading.  Morrison is a serious writer and deals with matters that are universal and each character that she develops speaks about the nature of love, passion, and they all are life-giving.

Morrison gives many oppositional structures in her novels – characters, plots, incidents, and ideologies – to show the readers that the world (and each one of us) is surrounded with so many “opposites” which are inevitable and it is the duty of the human beings to cull the best out of them.

Her characters and themes are life-affirming / life-denying or life-affording / death-dealing or having positive / negative attitudes.  However, they all describe that love for oneself and others are the only measure that would make the world move.
An Ecofeminist Reading of Han Kang’s The Vegetarian
Authors: Bright Shilpa
Published: June 2021

Ecofeminism depicts the movements and philosophies that establish a close relationship between women and nature. It is also an academic movement that sees a critical connection between the domination of nature and the exploitation of women. The term ‘Ecofeminism’ was coined by the French writer Francoise d’Eaubonne. This term intersects the two critical perspectives- ecology and feminism.  Ecofeminist theory asserts that a feminist perspective of ecology does not place women in the dominant position. This theory can be used to explore the connection between women and nature in culture, religion, literature and thus address and bring out the parallels between the oppressions of nature and the oppressions of women. Using gender as an important factor, ecofeminism examines the conditions that cause and perpetuates the subordination of both women and nature. This analysis includes seeing men as the curators of culture and women as the curators of nature, and also how men dominate women and humans dominate nature. This paper titled, ‘An Ecofeminist Reading of Han Kang’s The Vegetarian’ discusses the term ecofeminism and how this theory can be analysed and applied in this book written by Han Kang, a South Korean writer who won the Man Booker International prize for fiction in 2016 for this particular book. The book is about a home-maker whose decision to stop eating meat after a deadly nightmare about human cruelty leads to various problems in her personal life. This paper mainly tries to bring out how women and nature are oppressed by the patriarchy and how both are showing resistance toward this dominance. It investigates how man colonizes nature and as well as women. There are various other books that can be analysed under this feminist theory but this book in a way different as the main protagonist of this book sees vegetarianism as a way of not causing any harm on anything, but asserting her identity and freedom in patriarchal society. Thus this paper brings of the various ecofeminist aspects that can be analysed in this book through the various contexts related to the protagonist.

Authors: Dzieniszewski Grzegorz , Kuboń Maciej , Pristavka Miroslav , Findura Pavol
Published: June 2021

A comparative analysis of performance of Diesel engines fuelled by diesel oil, methyl ester of rapeseed oil and raw rapeseed oil was performed. The analysis of external characteristics of engines powered by various fuel types was accepted for an assessment. Engine performance rates were analysed while attention was paid to power courses, moment, unit fuel consumption and hour fuel consumption, exhaust fumes temperature and exhaust smoke. Operation effectiveness of engines was assessed when they were fed with various fuel types and optimal proportions of fuel mixtures were indicated. Environmental aspects of powering the engines with traditional fuels and crop-based fuels were analysed. The total CO2 emission in the entire process of manufacturing and combustion of fuels was accepted as a criterion. A simplified economic analysis was performed in the aspect of the underlying purpose of using crop-based fuels for propulsion of piston engines. Conclusions and recommendations that indicate directions of development concerning the analysed issue were prepared.
Acceptance of Transgender Veterans in Social Settings: An Experimental Study
Authors: Tremblay Andrea , Oliveira Justina M. , Pinard Kayla
Published: June 2021

U.S. society has become more exposed to and aware of the issues facing veterans who identify as transgender, but there is limited research surrounding this topic and the levels of acceptance society has of these individuals in social settings. With the growing “out” transgender population and changing views within political and military realms on transgender identities, there are concerns for the mental health and equal treatment of these individuals. This experimental study examined how participants reacted to a scenario in which they met a veteran in a social setting who shared a similar hobby (conditions: someone who either self-discloses they are transgender or an identical scenario except with no self-disclosure of transgender identity). This study explored the psychological attitudes that may impact these judgements and examined participants’ expected future behavior regarding the extent to which they would want further contact with that person. Results regarding likability were in the opposite direction hypothesized, such that participants reported the individual to be more likable in the condition where the person self-disclosed their transgender identity compared to the condition where transgender identity was not indicated, t(120) = −2.87, p = .005, d = 0.52. Perceptions of similarity and willingness to spend more time with the person were not significantly different across conditions. These results suggest more positive attitudes toward transgender veterans than initially expected, which is surprising and also promising for future research with the veteran transgender community, yet future research to further understand how generalizable these findings are may be critical.

Published: June 2021

Although more students are enrolling in college than ever before, far too many fail to complete their degrees. The financial, personal, and societal costs of leaving college can be high. The current study explored the relationship between 2 key psychosocial factors, social support and coping, and 2 measures of psychological well-being; specifically, life satisfaction and perceptions of the campus environment, both of which have been related to grade point average (GPA) and student retention. Path analysis results indicated that social support (B = .31, p < .001) and life satisfaction (B = .36, p = .005) were positively related to perception of university environment, whereas the use of problematic coping strategies (B = −.42, p = .003) was negatively related to perception of university environment. In addition, higher class year (B = −.11, p = .004) and first-generation student status (B = −.25, p = .013) were negatively related to GPA. These findings suggest that university efforts to help students develop positive social support resources and effective coping strategies have the potential to increase both psychological well-being and academic success.
Social Media Use in Emerging Adults: Investigating the Relationship With Social Media Addiction and Social Behavior
Authors: Larson Lauren
Published: June 2021

In the 21st century, use of online communication has skyrocketed, and this is particularly true for young people who have grown up in the age of the smartphone. In the world of online communication, adolescents and young adults especially seem to gravitate toward social media. The present study examined a mediational model wherein social media use in emerging adults predicts social media addiction through altered social behaviors, including face-to-face interactions, communication apprehension, and social skill deficits. More than 100 undergraduate students reported on their social media use and social behaviors via an online questionnaire. Contrary to expectations, social media use was only significantly correlated with social skills deficits, r(108) = .204, p = .017, and social media addiction, r(108) = .495, p < .001. Face-to-face interactions, communication apprehension, and social skills deficits did not function as mediators of the relationship between social media use and addiction and had no significant correlations with social media addiction. A modified mediation model is proposed, wherein impoverished face-to-face behavior and communication apprehension predict social skills deficits and those deficits predict social media addiction only when social media use is high.
Differentiating early from later diagenesis in a Cretaceous sandstone and petroleum reservoir of the Cedar Mountain Formation, Utah

Published: June 2021

Previously published anomalous whole-rock stable isotopic values from the Poison Strip Sandstone Member of the Cretaceous Cedar Mountain Formation (CMF) of eastern Utah are of uncertain origins. This study investigated the diagenetic history and the processes responsible for these anomalous data. Accordingly, we integrated photomicroscopic techniques including polarized light microscopy, epifluorescence and cathodoluminescence (CL) imaging, micromilling of stable isotope samples, and fluid-inclusion heating and freezing measurements to this end. The key observations involved the microscopic mapping of calcite cement stratigraphy using CL imaging to permit the analysis of stable isotopes of calcite cements that crystallized during early and late diagenesis. The mapping of calcite cement zones of sufficient submillimeter size to mill out and isolate microgram-sized stable isotope samples enabled this discrimination. Early diagenetic calcite cements have the most positive δ18O values (-10 to -8.5‰ Vienna Pee Dee Belemnite [VPDB]) of all components. The pattern of δ13C and δ18O variation in this early diagenetic cement indicates affinities with early meteoric diagenesis previously documented in published literature on the CFM. The late diagenetic calcite cements yield the most negative δ18O values (-18 to -16‰ VPDB). We interpret the late diagenetic cements to be responsible for the anomalously low whole-rock δ18O values previously reported from the Poison Strip Sandstone Member. Our discoveries of bitumen in late-stage pore fillings and liquid petroleum in the fluid inclusions of late diagenetic calcite cements of the Poison Strip Sandstone Member explain the lower whole-rock organic matter δ13C values and anomalous Δ13C values reported from the unit. Comparatively lower carbonate δ18O and organic δ13C values originally derived from whole-rock analyses of samples from the Poison Strip Sandstone Member resulted from high-temperature basinal diagenesis (hydrothermal circulation and/or petroleum migration), rather than the alternative interpretation of early diagenesis related to a Cretaceous paleoclimatic perturbation. Our results are illustrative of methods to resolve the long-standing geologic problem of discriminating and characterizing products of early vs. late diagenesis in terrigenous clastic sedimentary strata.

Authors: Kamaev A. V.
Published: June 2021

Introduction. Uncontrolled bronchial asthma (BA) increases risk of hospitalizations, future exacerbations and decreases quality of life; factors improving the probability to achieve BA control are under study.

Methods and materials. The open prospective study included 104 patients of three groups: children (6—11 years, n=38), adolescents (14—17 years, n = 35) and adults (25 — 50 years, n = 31). Inclusion criteria: BA duration >12 month, uncontrolled asthma, absence of acute respiratory infection for 14 days. Clinical history, respiratory function and sampling (serum and nasal brushings) for periostin assay were performed on Visit 1. Maintenance therapy correction and triggers avoiding recommendations were made. Two further visits 6 months apart were done. Statistical processing included ANOVA (Kruskall — Wallis test) and Pearson correlation test. Differences were considered significant when p<0.05.

Results. 75 % of «Children» group,70.6 % of «Adolescents» and 53.6 % of «Adults» had achieved BA control. Obesity, non-atopic phenotype, FEV1 <65 % of predicted were risk factors of uncontrolled BA. Serum periostin levels were highest in uncontrolled BA subgroup, Me [Q25; Q75] =32.9 [28.6; 39.1] ng/ml. Nasal periostin levels were highest in «Adolescent» group: 9.8 [4.8; 11.2] ng/ml. Nasal periostin and low FEV1 had moderate reverse correlation (r=—0.61).

Conclusion. Serum and nasal periostin levels could indicate treatment efficacy and prognose future risks of BA control loss.

Optimization Design of Coal Dryer Using Genetic Algorithm in Power Plant
Authors: Luluk Karlina Diyajeng , Bintang Ilham
Published: June 2021

Coal that is often used in Steam Power Plants is a type of Low Rank Coal (Low Rank Coal) which has a caloric value of 4200 kcal / kg with a moisture content of 40%.  Coal with water content that reaches 40% can cause the efficiency process of the plant to be not optimal. Low efficiency values will cause the use of electricity to increase and the combustion process to be incomplete so that it can cause many losses to the Steam Power Plant. From this problem, there needs to be a process of drying coal in order to reduce water content, the technology used in the process of drying coal is coal dryer. Design of coal dryer required source of steam or heat for drying process. Steam Power Plant there is steam waste extraction from turbines that can be used as a heat source to heat coal. If this extraction vapor is utilized, it can reduce the load from the condenser. The amount of turbine extraction steam that can be received by the coal dryer depends on the design of the coal dryer, because the design process of the coal dryer will affect the availability of energy in the coal dryer. This paper will discuss about optimization calculation with genetic algorithm method, to obtain the best design of coal dryer so that the heat received can be maximized so that the drying process becomes faster.
Implementasi net neutrality di indonesia ditinjau dari undang-undang ite
Authors: Pamungkas Satriyo Widhi
Published: June 2021

The problem of net neutrality has become a debate in many countries where the regulation on the net neutrality policy confirms that internet providers or Internet Service Providers (ISPs) are not allowed to make distinctions or be discriminatory in the selection of internet applications or content to be used by consumers or users. The purpose of this research is to analyze the application of network neutrality from the perspective of Indonesian law which specifically examines critically the applicable Information and Electronic Transactions Law. This research method is descriptive qualitative. The results show that the implementation of Net Neutrality in terms of the Information and Electronic Transactions Law is still not optimal because there are still network restrictions that are applied to certain Internet Network Providers. The results also show that there is a need for amendments to the ITE Law related to the enforcement of legal protection with the principle of forming a prohibition against the actions of Internet Service Provider (ISP) business actors that can disrupt the business climate.

ZARZĄDZANIE INNOWACJAMI W METROPOLII SZTOKHOLMSKIEJ
Authors: Danielewicz Justyna
Published: June 2021

Metropolitan areas are hubs of productivity and innovation. Although innovation can happen anywhere, it is usually concentrated in heavily urbanised areas. Cities therefore play a key role in the expansion of productivity and are drivers of economic development. Benefits created by cities reach beyond their borders. The impact of such spreading from cities to smaller towns and their surrounding and neighbouring regions is considerable, as is their positive economic influence manifesting in a radius of up to 200-300 km (OECD 2015). It is therefore vital to support innovation in order to internationally promote the competitiveness of metropolitan areas, thus consequently advancing whole regions and countries. Such development necessitates inter-sectoral collaboration, first and foremost, according to the Triple Helix concept, the collaboration of business, science and public authorities. This depends upon forms of collaborative governance at a regional and local level, which can set agreed priorities and operationalise this approach. This paper sets out to identify the forms of cooperation taken in Metropolitan Stockholm to generate innovation. The methodology applied in this research uses critical secondary data analysis, mainly the subject-matter literature and documents issued by public institutions. The paper starts with an introduction illustrating the meaning of innovation in the rise of competitiveness and development in metropolises. The next part of the paper elaborates on the concept of governance as the basis for cross-sectoral collaboration, to subsequently move to the core of the thesis, devoted to the analysis of good practice in innovation networks, particularly in ICT, life science and green economy. The summary indicates the main success factors.

LITERATURA E HISTÓRIA: O ROMANCE DESMUNDO E A REALIDADE DAS MULHERES ÓRFÃS NO BRASIL COLONIAL
Authors: Correia João Otávio Bastos , Araújo Fátima Maria Leitão
Published: June 2021

O presente artigo tem por objetivo analisar a realidade das mulheres órfãs no Brasil colonial, a partir do romance Desmundo, da escritora Ana Miranda. O intento é revelar a importância da narrativa literária para a compreensão da histórica ou das representações sobre o contexto social do Brasil no início da colonização. A narrativa nos conduz aos fatos ocorridos no Brasil em meados do século XVI, mostrando-nos a possibilidade de utilizarmos a literatura para nos reportarmos a fatos reveladores de um momento vivido e, que muitas das vezes, passaram despercebidos e invisibilizados em escritas totalizantes e lineares da História. Partindo dessa perspectiva, com a presente escrita buscamos promover o diálogo interdisciplinar entre literatura e história, tendo por foco o romance que relata a vinda de moças de Portugal para o Brasil na época da colonização para casar e a vida difícil que essas mulheres tinham, dentre essas destaca-se Oribela, a protagonista da obra em análise, cuja vida desvela as condições e sujeições as quais eram submetidas jovens mulheres órfãos transportadas à colônia para atenderem às necessidades dos colonos sob os auspícios da Igreja Católica. Tendo em vista as novas abordagens historiográficas, a literatura passa a ter papel de destaque na pesquisa, pois a partir da literatura chegaremos a compreensão social daquele periodo segundo a obra Desmundo.
A EDUCAÇÃO INFANTIL E A BNCC: REFLEXÕES SOBRE A CONSCIÊNCIA FONOLÓGICA
Authors: Mello Ana Paula Barbieri de , Sudbrack Edite Maria
Published: June 2021

O presente artigo transita pela fundamentalidade da Educação Infantil como etapa da Educação Básica. Tem o propósito de analisar o lugar da Consciência Fonológica apresentado na Base Nacional Comum Curricular - BNCC, enquanto mecanismo para contribuir com a leitura e escrita. O estudo, de natureza qualitativa, apoia-se na pesquisa bibliográfica e seus balizadores teóricos e considera a perspectiva histórico-crítica na abordagem metodológica, assim como, pauta-se na análise de conteúdos para a descrição, compreensão e interpretação dos materiais. A reflexão incursiona pelo conceito de Consciência Fonológica (reflexão e manipulação dos sons da fala), alertando para a frágil e superficial contribuição desta categoria no documento da BNCC, visto da sua importância e do seu estímulo desde a Educação Infantil como aporte para o posterior desenvolvimento adequado da leitura e escrita, levando em consideração a herança histórica do fracasso escolar (analfabetismo, dificuldades escolares e evasão escolar), o qual necessita de políticas educacionais mais efetivas. Destacamos que o desenvolvimento adequado da leitura e escrita é um dos principais desafios do sistema educacional brasileiro. Assim, advoga-se que a Educação Infantil seja alçada ao nível de importância que lhe é devido, haja vista as possibilidades de desenvolvimento da criança em diferentes áreas, que a mesma propicia, superando a descontinuidade das ações e das reformas por vezes desnecessárias e assentadas em paradigmas equivocados. Exige-se, com efeito, recursos, pesquisas e formação docente direcionadas à qualidade dos processos educativos, fazendo frente às desigualdades educacionais e sociais.
Electroencephalogram and pitfalls in children: Benign variants and how they can be misinterpreted
Authors: Shahid Asim
Published: June 2021

Electroencephalogram (EEG) has been a useful tool in the diagnosis of epileptic and non-epileptic findings for about 100 years now. The interpretation of this test requires added training for neurologists in epilepsy and EEG reading. There are many findings that may be misread or overcalled as abnormal when the findings are actually normal variants in specific age groups. A misdiagnosis may result in unnecessary medications or other treatments that can potentially result in morbidity and even mortality, the latter being seen in incorrect diagnosis of status epilepticus leading to aggressive therapies. Available history and careful analysis of the EEG used together at the time of interpretation can avoid these sources of morbidity and mortality as well as a misdiagnosis of epilepsy.
Magnetic resonance imaging brain sequences in pediatrics
Authors: Kamble Ravindra Bhimrao
Published: June 2021

There are various pediatric magnetic resonance imaging (MRI) protocols followed in institutes and by individual radiologists, determined by the disease process and the indication for imaging, to narrow down the differential diagnosis. Most times, it is beneficial to modify protocols when the scans are being done, based on the findings seen on initially acquired sequences. This is particularly useful in pediatric patients considering most of them are scanned either under sedation or general anesthesia, and repeat scans will be cumbersome. In this particular review article, we are going to discuss appropriate MRI sequences in scanning pediatric brains and the need for rapid MRI sequences. This is of immense importance as MRI in pediatric patients poses challenges both to radiologists and technologists. Consequently, appropriate MRI protocols should be set to avoid repeat studies.

The population of millennials who work as elementary school teachers is currently increasing because it replaces the previous generation who will retire. This generation grows surrounded by technology and educates technology savvy too. This study aims to explore the experience of millennial teacher related to the use of technology in learning in primary schools. Two research questions were proposed, namely: 1) How did millennial teacher experience their role as teacher for elementary school students? ; 2) What is the experience of millennial teacher when using technology in learning for students in elementary schools. This study uses a qualitative method with the Interpretative Phenomenological Analysis (IPA) approach. Semi-structured interviews with open-ended questions were conducted on 6 elementary school teacher. The analysis showed four emergent themes, namely: (1) Interpersonal experience; (2) Technology as a learning tool; (3) Barriers to integrating technology in learning; (4) Strategy to overcome obstacles. Collaborative, and collegial relationships will help the subject to make an active contribution at work. Familiarity with technology helps millennial teachers in innovating learning and interacting with students.
Exploring the profiles of pre-service teachers technological pedagogical content knowledge (TPACK) on earth and space science offline and online course
Authors: Rukmana Diki , Handayani Sri Lestari
Published: June 2021

This study reveals the comparison of the TPACK profiles of pre-service elementary school teachers in the Earth and Space Science (ESS) offline and online lectures. The sample consisted of 97 students who took offline lectures in the 2018/2019 academic year and 85 students who took online lectures in the 2019/2020 academic year. The research instrument consisted of 38 questionnaire items that assessed the self-efficacy of the TPACK-21 components. The correlation analysis results show that in all aspects of basic knowledge and secondary knowledge, ESS online courses provide better results in developing TPACK abilities than offline courses. However, the SEM analysis results show that the structure of the TPACK ability development model in the offline class appears to be more stable than the online class. This indicates a need for further development in online learning strategies and approaches to lead to a more significant contribution to the development of TPACK.
Analysis of the Information Needs of Volunteers: the Results of Study
Authors: Mazarakii Elena Y.
Published: June 2021

Volunteering is actively developing in the Russian Federation and around the world. Society that takes part in volunteer projects has a high level of civic identity, morality and forms humanistic values among young people. Volunteer movement is a tool to reduce the level of antisocial and extremist behaviour.

Approximately 15% of the population of the Russian Federation is involved in volunteering activities at the present time. Thanks to the volunteer organizations created in educational institutions, the government creates positive image of a volunteer. At the same time, there is a problem of public distrust in this type of activity due to the lack of awareness of volunteer organizations and their projects. Organizers of the volunteer movement face the problem of lack of information about volunteering that entails the difficulties in setting goals and objectives of the volunteer organization. It is necessary to identify the information needs of volunteers, as well as to create an information field where they can meet these needs.

There is no resource with comprehensive information about volunteering activity in Russia. Information needs of participants in such type of projects cannot be fully met. The main source of information is the portal “Volunteers of Russia”. It allows you to get e-book of a volunteer, register a volunteer organization, create an event and apply for participation in an existing project. However, the system has a number of factors that make it difficult to keep accurate records of volunteer activities; it is more designed to attract attention to projects.

In 2018—2019, the study was conducted using the online survey (questionnaire). The survey involved volunteers (451 respondents) and their leaders (43 respondents) of the St. Petersburg Volunteer Movement “Our Future is in Our Hands”. The purpose of the study was to identify the information needs of volunteers and their managers. The survey results led to the conclusions: the availability of information resources on volunteering is not too high; the most interesting information is related to the experience of implementing volunteer activities, project development and management, the development of supra-professional skills. Volunteers prefer to use electronic documents.

It is necessary to develop special programs and organize training courses on the formation of information culture of volunteers, to create a wider range of information resources for volunteers. One of the possibilities is to create a unified public resource that reflects different aspects of volunteering activities. It is important to form a comprehensive information support for volunteers.
Natural Attenuation as a Decontamination Approach for SARS-CoV-2 on Library Materials
Authors: Fedotova Maria V.
Published: June 2021

Based on the current scientific understanding regarding COVID-19, this article presents the results of new studies (Tests 4, 5, 6), conducted by the Institute of Museum and Library Services (IMLS) and the Online Computer Library Center (OCLC), in partnership with Battelle. The purpose of the experiments is to determine how long frequently circulated library, museum and archival materials should be quarantined before being put back into public circulation.

Each test has been conducted by applying the virulent SARS-CoV-2 virus on various materials held at standard room temperature and relative humidity conditions, and then examining the rate of natural attenuation of the virus. The items were not sterilized before testing. Battelle propagated the clinical isolate of the SARS-CoV-2 virus in-house, followed by characterization and testing to establish a certified titer. The materials in Test 4 included binding and cover items placed in a stacked configuration to imitate the common practice that libraries employ when handling book/DVD returns, as well as expanded polyethylene foam, which is typically used in museums for storage and shipping. Test 5 focused on textiles, while Test 6 included building materials (glass, marble, brass, laminate, and powder-coated steel). Test coupons cut from the materials were inoculated with active virus, and then allowed to dry. The test coupons were then examined at the following timepoints: on the second, third, fourth and sixth day (Test 4); on the second, fourth, sixth and eighth day (Tests 5 and 6). The results of the tests showed how much virus was detectable at the selected timepoints. In Test 4, the virus was still detected on all the five materials after six days. In Test 5, the virus was still detected on leather and synthetic leather publication after eight days. In Test 6, the virus was not detected on the tested materials after six days.
