МОДЕЛИРОВАНИЕ ЭНЕРГИИ СОСТОЯНИЯ ЦЕЛЛОБИОЗНОГО ЗВЕНА. МЕХАНОХИМИЧЕСКОЕ ВОЗДЕЙСТВИЕ
Authors: Мамылов С.Г.
Published: July 2021

Целлобиозное звено – первичный элемент цепи природного полимера целлюлозы. Известна модель строения целлюлозной нити, где звено – остатки моносахарида β-D-глюкопиранозы, соединенные мостиковыми атомами кислорода через 1 (гликозидная связь) и 4 атомы углерода. В другой модели целлобиозное звено состоит из двух глюкопиранозных остатков. В модели кольца углеводных остатков также соединены между собой гликозидной связью и развернуты друг относительно друга на 180 градусов (торсионный угол). Эти соображения переносятся и на дисахарид целлобиозу. В работе приводится квантово-химическое моделирование энергии состояния целлобиозного звена в зависимости от торсионного угла. В качестве начальных состояний выбраны две названных модели. Показано, что обе модели после оптимизации положения атомов сводятся в одну, где торсионный угол между глюкопиранозными кольцами составляет 112 град. Возможность вращения колец по гликозидной связи маловероятна. Это обусловлено наличием потенциального барьера, сравнимого по высоте с энергией активации химической реакции, например, распада целлобиозного звена. Механохимическая активация реагентов известна как метод воздействия, позволяющий получать продукты, малодостижимые другими методами. При механохимической активации возможно образование активных промежуточных продуктов (интермедиатов), определяющих альтернативные маршруты реакции. При невозможности вращения колец моносахаридов целлобиозного звена, рассматриваются модели интермедиатов, которые могли бы объяснить как разрыв связей целлюлозы по целлобиозному звену, так и образование активных продуктов. Представлены структуры ангидропиранозных соединений, возможных продуктов разложения целлобиозного звена. Такие соединения могут рассматриваться, как результат механохимического воздействия. На основании моделирования термодинамических параметров исходного соединения целлобиозы и представленных продуктов оценены маршруты разложения.
МАГНИТНЫЕ СВОЙСТВА СИНТЕТИЧЕСКИХ АНАЛОГОВ ФОСФАТОВ-АРСЕНАТОВ МЕДИ, ИМЕЮЩИХ ПРИРОДНЫЕ ПРОТОТИПЫ: САМПЛЕИТ, ЛАВЕНДУЛАН, ЕПИФАНОВИТ, АНДИРОБЕРТСИТ

Впервые получены синтетические аналоги, и охарактеризованы магнитные свойства следующих минералов – представителей группы лавендулана: самплеита – NaCaCu5(PO4)4Cl∙5H2O; андиробертсита – KCdCu5(AsO4)4[As(OH)2O2]∙2H2O; лавендулана - NaCaCu5(AsO4)4Cl∙5H2O; епифановита - NaCaCu5 (PO4)4[AsO2(OH)2]·7H2O. Из температурной зависимости магнитного момента образцов известной массы в постоянном магнитном поле, с использованием данных об истинной плотности природных прототипов, найдена температурная зависимость магнитной восприимчивости всех названных соединений в интервале температур от 2 до 300 К. Установлено, что все четыре соединения являются антиферромагнетиками. Из дифференциальных кривых, отражающих зависимость первой производной магнитной восприимчивости по температуре от температуры, найдены точки Нееля, выше которых рассматриваемые соединения теряют свои особые магнитные свойства, превращаясь в парамагнетики. Несмотря на то обстоятельство, что первый представитель рассматриваемой группы минералов – самплеит обнаружен в природе более 7 десятилетий назад, характеристика их магнитных свойств даётся впервые и стала возможной благодаря успешному получению их синтетических аналогов, достаточно чистых для исследования физических свойств. Идентификация полученных синтетических аналогов осуществлялась рентгенофазовым методом по порошковым дифрактограммам, с использованием электроннозондового микроанализатора с энергодисперсионной приставкой выполнены определения состава по элементам с Ar≥23 а.е.м. Этим же методом подтверждено отсутствие примесных фаз. Установлено, что аналоги самплеита, лавендулана и андиробертсита демонстрируют сходное поведение в магнитном поле на рассмотренном интервале температур, аналог епифановита имеет существенно более низкую точку Нееля и более высокую магнитную восприимчивость на всём исследуемом интервале температур.

В работе представлены результаты исследования по повторному комплексному диффузионному насыщению детали «упорный подшипник скольжения» из стали 45 после проведения его ремонта. Ремонт подшипника после одновременного комплексного диффузионного насыщения бором, хромом и титаном, отработавшего до износа 18 месяцев, осуществлялся путем снятия упрочняющего покрытия методом шлифования на глубину 0,15 ммна плоскошлифовальном станке. Одновременно с подшипником, аналогичной процедуре подвергали образец-свидетель, который ранее был упрочнен одновременно с данным подшипником. После проведения операции химико-термической обработки подшипника и образца-свидетеля, контроль и измерение толщины и характеристик диффузионного покрытия производили на образце-свидетеле. Диффузионное покрытие на подшипнике до его ремонта имело толщину 120–150 мкм. Переходная зона, представленная преимущественно перлитом толщиной 450 мкм. Общая толщина диффузионного покрытия, таким образом, составляла порядка 600 мкм. Толщина диффузионного покрытия на отремонтированном подшипнике выросла до величины 0,9–1 мм, из которых приблизительно 0,7–0,8 мм приходится на переходную зону. Толщина слоя боридов также выросла до 180–200 мкм. Поверхностная твердость боридного слоя выросла на 60% – с 1100 до 1800 HV0,1. При этом в целом твердость диффузионного покрытия, измеренная по методу Виккерса при нагрузке 1 кг, выросла с 2243 до 2764, что составляет 23 %. Более высокая твердость поверхности позволят значительно сократить износ боридного слоя и, как следствие, значительно увеличить ресурс работы подшипника скольжения после проведения его ремонта.

В работе приведены результаты металлографического анализа микроструктуры высоколегированной стали Uddeholm Sverker 3 (AISI Type D2). Обработка холодом высоколегированных сталей находит применение как способ уменьшения количества остаточного аустенита, и как следствие – стабилизация механических свойств и размеров прецизионных деталей. В настоящей работе применяли обработку глубоким холодом путем погружения в жидкий азот после термической обработки по традиционной технологии (закалка на первичную твёрдость и низкий отпуск). Выдержку в жидком азоте осуществляли в течение 24 часов. По окончании выдержки детали извлекали из жидкого азота и выдерживали при комнатной температуре до достижения деталями комнатной температуры. Далее подвергали низкотемпературному отпуску при 170°С. образец, подвергнутый криогенной обработке, имеет более заметные флуктуации химического состава и большее количество карбидной фазы (соответственно 30 и 27 об. %). Флуктуации химического состава выражены в более интенсивной окраске карбидных частиц при помощи цветного травления, что свидетельствует о различия в химическом составе карбидных частиц. в случае криогенной обработки средний удельный размер карбидов меньше, чем в случае отсутствия криогенной обработки. Кроме того, в обработанном холодом образце наблюдается повышение содержания ультрамелких карбидов, что логично объясняется выпадением их из остаточного аустенита при его распаде в условиях криогенных температур. распад остаточного аустенита и вследствие этого – выделение дополнительных объемов карбидных частиц. Выделяющиеся при криогенной обработке частицы можно отнести к ультрамелким, со средним диаметром порядка 1 мкм.

O presente trabalho teve como objetivos caracterizar e quantificar as lesões de bovinos enviados para abate em um frigorífico localizado na região centro-oeste do estado de Goiás, Brasil, cuja carne é destinada principalmente à exportação. As lesões foram classificadas de acordo com sua extensão e gravidade em: grau 1 - hematoma leve, grau 2 – hematoma intermediário e grau 3 – fratura. A ocorrência de tais lesões foi relacionada a condutas inadequadas de manejo pré-abate no âmbito do estabelecimento sendo para tanto considerados: densidade animal nos currais de espera, deslizamentos e quedas no desembarque, uso de bastão elétrico desde o desembarque até o box de insensibilização e número de vocalizações durante a condução dos animais. Ao final, foi observado que 100% dos animais apresentaram algum tipo de lesão sendo que as mais frequentes foram as de grau 1 (100%) seguidas de 2% de frequência para as lesões de grau 2. Estas foram relacionadas a falhas ocorridas fora do abatedouro frigorífico nas etapas de embarque e transporte tendo em vista que o estabelecimento atendeu os requisitos de boas práticas sob o ponto de vista do bem-estar animal.

Authors: Baskoro Farid , Rohman Miftahur , Nurdiansyah Aristyawan Putra
Published: July 2021

Serial Peripheral Interface (SPI) is a synchronous serial communication whose data or signal transmission involves Chip Select (CS) or Slave Select (SS) pins, Serial Clock (SCK), Master Out Slave In (MOSI), and Master In Slave Out (MISO). In the Arduino Uno, there are four pins that allow Arduino Uno to perform SPI communication. In this research, SPI communication is implemented to expand the output of the Arduino Uno by using the features of the MCP23S17 IC so that the Arduino Uno, which initially has 20 output pins, can expand to 36 output pins.The results of the research show that the Arduino Uno manages to control 36 output pins. 16 output pins from the MCP23S17, 16 output pins from the Arduino Uno, and 4 pins are used for the SPI communication line. The results of this study also show the form of the SPI communication signal from Arduino Uno in declaring 21 registers on MCP23S17, declaring the MCP23S17 pin register as output, and implementing the output using LEDs.

Published: July 2021

Container Crane (CC) is heavy equipment that functions to unload or load containers from the dock to the ship and vice versa, this crane has a measuring device, namely an hourmeter which functions to show how long this crane has been running based on the number of hours. from this hourmeter will be used as a reference for the technician team to carry out maintenance or replacement of a spare part. So far, checking the hourmeter is done manually by visiting the crane one by one and looking directly at the analog hourmeter. For this reason, an hourmeter monitoring system is needed to make use of the Internet of Things to make it more effective. In supporting this system, we use a voltage sensor as a detector that the crane is on, the RTC is a type of timer, the ESP32 is a microcontroller that is equipped with a wifi module, MySQL as a database and web to display digital data from the microcontroller. This hourmeter tool can be used as hourmeter monitoring on Container Crane via the web. This system can display data on the microcontroller which can be viewed via the web and provide notification in the form of an email to the user if the value on the hourmeter has reached the specified limit to prevent damage to the crane due to delays in the maintenance process.

Published: July 2021

Umbrella Monopole Antenna (UMA) proposed in this paper for 5G application. We designed four models of UMA, i.e: UMA-A, UMA-B, UMA-C, and UMA-D. The antenna has a curvature in the patch as an umbrella shape with a feeding shape a microstrip feed line. Four variations of the patch antenna have been designed and get different performance in VSWR, surface current, and directivity. The proposed antenna has a wide bandwidth that operates 8 GHz 30 GHz with VSWR <2 dB. The Increasing of directivity is reached for UMA-A, UMA-C, UMA-D, and UMA-B, i.e: 6.38 dBi, 7.97 dBi, 8,84dBi, and 9,15 dBi respectively at 24 GHz.  The maximum gain has been reached for UMA-B of 9.15. The lowest frequency that has a return loss of 10 dB has resulted for UMA-D in the frequency around 5 GHz. All of the UMA antennas can be applied for 5G mmwave applications at 24 GHz and 28 GHz.

Published: July 2021

En el conflicto armado existen factores sociales y culturales invisibles para la sociedad, lo cual hace imposible la creación de programas de atención social y en salud que den cuenta de las realidades que viven las personas. Es decir, una cosa es lo que piensa el gobierno de turno que necesitan las poblaciones víctimas de la violencia en Colombia y otra cosa muy diferente son las realidades que viven las personas en sus comunidades. El objetivo de este documento es demostrar cómo los aspectos sociales y culturales de una población víctima de la violencia en Colombia son determinantes para el desarrollo social y el éxito de los procesos de reparación. Resultados: Se identificó una categoría núcleo: “Realidades invisibles del conflicto armado en Colombia”; y cuatro categorías emergentes; “Poder social”, “Estado y soberanía”, Salud mental, individual y familiar” y “Productividad territorial”. Conclusiones: La búsqueda de realidades invisibles del conflicto armado en Colombia, nos permite encontrar personas subsumidas en la cultura de la destrucción, con daños en su alma, suplicando mínimas condiciones para vivir, sin palabras para expresar su dolor, sin procesos solidarios y comunales, sin estructuras para el progreso; quienes en su precaria dignidad humana se someten ahora a una reparación que promete igual tratamiento al territorio, la persona, la familia y los colectivos. Este artículo da cuenta de la fase cualitativa de la investigación denominada: Programa de atención psicosocial y salud integral a víctimas del conflicto armado, Algeciras (Huila), Colombia 2018.

Herd Behavior of Investors and Default Risks of P2P Online Lending
Authors: Seon Junghoon , Han Sukman
Published: July 2021

We examine the impact of investors’ herding on the default risk of P2P online loans. More specifically, we first decompose the number of investors in each loan into two components: the component caused by public information and the component reflecting factors other than public information. Then we investigate the effect of each component on the default risk of loans, using an ordered probit analysis. We use the data on 3,720 loans that were traded through 8percent, a Korean price-posted P2P platform from February 2015 to December 2017. We find the results as follows: First, the number of investors is determined by information that are provided by the platform and macro-economic variables (hereafter public information). Second, the number of investors explained by public information decreases the default risk of the loans. However, the number of investors reflecting factors other than public information increases the default risk of the loans. These results are interpreted as an evidence supporting ‘herding’ hypothesis: Investors follow intentionally other investors’ investment decision. These results suggest that the quantity increasement and quality improvement of public information provided by a P2P platform can improve the efficiency of P2P lending market reducing herding caused by factors other than public information.

Published: July 2021

This study explores community participation in disaster management in Surakarta. The method used in this research is descriptive qualitative with interactive data analysis. The research data is in the form of primary and secondary data which were extracted through interviews, observation and documentation. The research flow includes literacy studies, field studies, problem identification and problem formulation, data collection, data processing, data analysis, reports and publications. The results showed that community participation in disaster management was evident at the disaster management stage. Communities together carry out rescue, evacuation and provision of emergency posts or evacuation. The community also works together in providing all the needs of the affected residents. Participation is not optimal in the pre-disaster and post-disaster stages. This is due to the lack of public awareness, the absence of firm sanctions and the absence of a forum for the community to work together with the government to plan and evaluate disaster activitie

The village government is at the forefront of implementing public services to ensure the welfare of the community, which is a determining factor for the success of government programs. Increasing the capacity of village officials is an action to create a prosperous society. The village government must make efforts to increase the capacity of its village apparatus considering that the quality of human resources in various villages is generally still low. Therefore, the purpose of this study is to describe the development of the capacity of the apparatus in the dimension of developing the capacity of the human resources of the apparatus. Data collection in this qualitative research was carried out through participant observation, in-depth interviews, and documentation. The informants in this study were the Village Head and the Secretary of Kenongo Village, Tulangan District, Sidoarjo Regency. The data that has been collected will then be analyzed using the interactive analysis model of Miles and Huberman. The results showed that the development of human resource apparatus capacity was carried out through technical guidance from the Village Community Empowerment Service (DPMD), the implementation of technical guidance had not been accompanied by enthusiasm from the Kenongo Village government apparatus. Apparatus capacity development in the IT field has also been carried out, but not accompanied by monitoring and evaluation stages, so that IT training only evaporates without soft skills for Kenongo Village Apparatus. The findings also show that the development of the human resource capacity of village heads also needs to be improved, especially in terms of the ability to communicate with village apparatus staff to create a conducive working climate in government administration. The obstacles in carrying out the development of the capacity of the Village apparatus human resources are the lack of enthusiasm of the village apparatus in following technical guidance, the disinterest / curiosity of the village apparatus in using IT, the existence of passive village officials in planning work programs, and the morale of the apparatus is decreasing, because the salary received is used up for pay bank installments.
Mechanical Behavior of Concrete Reinforced with Waste Aluminium Strips
Authors: Channa Imran Ali , Saand Abdullah
Published: July 2021

The main objective of this research work is to investigate the influence of the addition of waste materials, like aluminium waste material, Soft Drink Tin Fibers (SDTF) or soft tins to improve mechanical properties of concrete and also study the strength behavior of concrete, such as flexural strength and indirect or split tensile strength. It has been acknowledged that the use of fibers in concrete has considerable effects to improve strength parameters and characteristics of concrete. In this research work, similar efforts are made to present the effects of soft tin fibers or aluminium waste material as a reinforcing material in concrete and to assess the mechanical behavior of concrete. Particularly, this research work aimed to investigate experimentally the effect of soft drink tins on tensile (cylinder splitting tensile strength) and flexural strength. Soft tin fibers of 25.4  5  0.5 mm in size were used and added from 1 to 5% by the weight of cement with the design mix of 1:1.624:2.760 at 0.50 w/c ratio. Therefore, 6 batches (every batch contained 3 prisms and 3 cylinders) were prepared and cast for evaluation of tensile and flexural strength. One batch was cast without inclusion of fibers (controlled batch) and remaining 5 batches were cast with the addition of fibers using 1, 2, 3, 4, and 5% respectively. It was revealed from obtained results that split tensile strength and flexural strength of specimen increases as compared to controlled batch up to 4% addition of fibers. Moreover, beyond 4% soft drink tin fiber level, strength begins to fall down. Thus, it can be suggested that mechanical properties of concrete can be enhanced by 4% of soft drink tin fibers. Moreover, in this study, soft drink tin fibers (SDTF) or aluminium waste are used as the application of utilization of waste materials as a partial construction material and also on another side it controls the solid waste and environmental pollution. Doi: 10.28991/cej-2021-03091718 Full Text: PDF

Las lecciones del silencio: María Zambrano y José Gaos ante José Ortega y Gasset
Authors: Sánchez Benítez Roberto
Published: July 2021

Los pensadores españoles María Zambrano y José Gaos fueron notables discípulos de José Ortega y Gasset, entendieron a su manera el “silencio” que su maestro guardó durante la guerra civil española, viviendo el exilio de manera singular. Sus interpretaciones remiten, por un lado, al problema de la palabra y el silencio que la circunda y la hace posible, sobre todo si es “profética”, mientras que, por el otro, aluden al sentido que llegó a tener la figura del intelectual ante ese nuevo fenómeno inédito que dominó el escenario de las sociedades occidentales en el siglo XX, a saber, la “masa”.

Black Bodies, White Bodies – ‘Gypsy’ Images in Central Europe at the Turn of the Twentieth Century (1880–1920)
Authors: Kovács Éva
Published: July 2021

The problem of the observer has long been a key concern of social theories. However, in mainstream sociology, it was not until three decades ago that the relationship between image and text, seeing and gaze, appeared on the horizon of the discipline. Studying the visual representation of Roma in Modernity, one sees how CentralEuropean societies create their own sexualised and feminised Blackness through ‘savage’ groups and individuals. The central thesis of the article is that, across Europe, the panoptic regime of Modernity operates with the optical unconscious in two ways. On the one hand, by re-visualising social differences that becameinvisible after the collapse of feudal society; on the other, by bringing the oppressed into sight and rendering the oppressors invisible. However, there is a significant difference between the Western and Eastern European representations of ‘savages’: in the process of nation-building, the ‘Gypsy’ became an ambiguous part of the national imaginary in Eastern European countries. The paper argues that ideas and visual representations of Roma commuted between Central and Western Europe resulted in tensions between the colonial and emancipatory gazes.
Contesting Stereotypes through Self-Representation? A Review of the Romani Exhibition Stands at the 2019 Frankfurt Book Fair
Authors: Tittel Laura Soréna
Published: July 2021

Romani literature was exhibited at the Frankfurt Book Fair at specific stands and events for the first time in 2019. This article reviews the presented literature and authors and discusses advantages and disadvantages of establishing the category “Romani literature” within the context of the Frankfurt Book Fair. It argues that the category provides a new platform for Romani authors as well as for Romani identity politics and was set up with the aim to fight existing racism against Roma. Making oneself visible as a diverse minority at such an event can help to break up stereotypes and constitutes a success after centuries of underrepresentation. At the same time, the article uncovers the danger of feeding into essentialism through the label “Romani literature” and reflects on the limitations of emancipatory politics when participating in a predominantly commercial event.

Authors: CANBULA Deniz
Published: July 2021

Periyodik tabloda on yedi adet nadir toprak elementi bulunur ve bunlardan on beş tanesi lantanitler grubunda yer alır. Diğer iki tanesi ise skandinyum ve itriyumdur. Bu çalışmada, hafif ve ağır olarak iki gruba ayrılan nadir toprak elementlerinden hafif grubuna dahil olan samaryum izotopunun fotonükleer reaksiyonuna ait tesir kesiti değerleri hesaplanmıştır. Hesaplamalar, farklı nükleer seviye yoğunluğu modelleri (Geri-kaydırılmış Fermi gaz modeli-BSFGM, Sabit sıcaklık modeli- CTM, Genelleştirilmiş süperakışkan modelGSM, Kollektif yarı-klasik Fermi gaz modeli-CSCFGM) kullanılarak TALYS 1.95 bilgisayar programı ile yapılmıştır. Elde edilen sonuçlar EXFOR (Uluslararası Nükleer Veri Merkezi) deneysel veri tabanından alınan deneysel veriler ile karşılaştırılmıştır. Sonuçlar incelendiğinde, kollektif yarı-klasik Fermi gaz modelinin (CSCFGM) deneysel verileri tahmin etmede ve açıklamada daha başarılı olduğu ve nadir toprak elementlerinin fotonükleer reaksiyonlarının tesir kesiti hesaplamalarında güvenle kullanılabileceği gösterilmiştir.

Published: July 2021

Esta investigación consistió en evaluar la solidez del color de tejidos de lana y alpaca tinturados con colorantes extraídos de plantas nativas de la provincia del Azuay en el sur ecuatoriano. Las plantas tintóreas que se utilizaron fueron: Lomatia hirsuta (garau), Baccharis latifolia (chilca), Juglans neotropica (nogal), Brachyotum confertum (killuyuyo) y además se empleó el colorante de origen animal Dactilopius coccus (cochinilla). Se utilizó la metodología ancestral para el teñido de los hilos, con los que se prepararon muestras de tejido de punto que sirvieron para realizar las pruebas de solidez del color a la luz artificial, lavado manual con jabón neutro y alcalino, y la prueba de frote en húmedo y en seco. La evaluación de la pérdida de color de los tejidos se realizó mediante un colorímetro, se midió el color antes y después de las pruebas y se calculó la diferencia total de color (ΔE). Se encontró una mayor variación del color en el tratamiento de lavado de las muestras con jabón alcalino (el valor más alto fue 32) y en el resto de las pruebas se observó una mínima diferencia de color (1,4 en promedio). Haciendo la relación con la escala de grises los resultados corresponden a la calificación de satisfactorio para la mayor parte de muestras, por lo que se demostró que el color de los tejidos al utilizar garau, chilca, nogal, killuyuyo y cochinilla, es estable a la mayoría de los factores ensayados. Estos resultados son importantes porque sirven de base para la aplicación de algunos procesos para obtener una mayor resistencia del color en indumentaria elaborada con hilos teñidos con biocolorantes.
Honouring Inuit Women’s Educational and Employment Experiences through Indigenous Storywork Methodology
Authors: Wasilik Tina
Published: July 2021

The legacy of the Arctic Residential School system is still present in Nunavut education today. Inuit in Nunavut continue to receive a westernized education that does not fully encompass traditional Inuit learning principles. However, a group of Inuit women, enrolled in a Northern College Early Childhood Education (ECE) Diploma Program from 2015-2017, uniquely blended a child-centred educational approach with traditional Inuit learning methods. Through the Inuit women’s practicum placements completed at a preschool, they developed self-confidence and a skill set that led to their employment and self-reliance. 

The Oxford dictionary defines self-reliance as “the ability to do or decide things by yourself, rather than depending on other people for help” (Oxford University Press 2021). This definition does not fully capture the essence of self-reliance from Inuit women’s perspectives. Their self-reliance is greatly tied to a combination of domestic work, wage work, and land-related work that forms a unique framework to capture the specificity of northern women’s self-reliance. My research study will explore the personal experiences of these Inuit women graduates. The study intends to inform institutional decision-making, determine how to best support the Inuit women’s educational access and success, contribute to the scholarly work in the field of education and advance future Inuit training and employment initiatives.  

My research questions are: What does self-reliance look like from an Inuit woman’s point of view? How did participating in the 2015-2017 ECE Diploma Program influence the Inuit women’s lives?

Indigenous Storywork is grounded in Indigenous Research Framework (Lavallée 2009) which allows for connections between people, their ancestors, and the natural world. Indigenous Storywork guides my study theoretically and methodologically. I will use Storywork to engage in holistic meaning-making that involves the heart (emotions), mind (intellect), body (physical actions), and spirit (spirituality) (Archibald et al. 2019). 

Storywork is essentially a three-part framework: story-making, storytelling, and connecting with specific cultures and peoples experiences through stories (Archibald et al. 2019). This framework honours distinctive traditional Inuit knowledge and these Inuit women’s holistic identity regarding their relationships with themselves, family, community, land, environment, and the wider society. Indigenous Storywork methodology creates space for my participants to share dreams, visions, spiritual encounters, and lived experience stories through interviews. My research honours the Storywork of Inuit women through their culturally responsive and unique educational opportunities.
A Brief Review of Young Children’s Home Digital Literacy Practices
Authors: Liu Yina
Published: July 2021

COVID-19 has created significant changes in the everyday lives of teachers, children and parents. Due to school lockdowns in the spring semester of 2020, teachers shifted from in-person classroom teaching into “emergent remote teaching” (Hodges et al. 2020, para. 5), where digital tools and software were used for instruction and teacher-student communications. Many children have also shifted their social lives from face-to-face to virtual interactions (Hutchins 2020); for example, engaging in online family story reading, social media participation, and joining after school activities digitally. This pandemic has highlighted the importance of being literate in digital environments for children. Digital literacy, that is, literacy practices undertaken across multi-media, involving “accessing, using and analysing digital texts and artefacts in addition to their production and dissemination” (Sefton-Green et al. 2016, p. 15). The importance of the digital world and digital tools for the post-COVID future where digital literacy could become more prominently featured for teachers, children, and parents must not be underemphasized.

 

In this presentation, I reviewed the literature on young children’s digital literacy practices at home. Many studies have illustrated the benefits and various kinds of learning that children get from their digital play at home, including emergent literacy learning (Neumann 2016), digital citizenship (Bennett et al. 2016), etc. Moreover, I presented the complex trajectories of children playing with their digital devices and toys at home (Marsh 2017). In the 21st century children’s home play, the boundaries between the virtual and physical worlds are blurring (Marsh 2010; O’Mara and Laidlaw 2011; Carrington 2017).

 

More importantly, this literature review suggests a gap and an opportunity for future researchers to explore home digital literacy of children, who are from minority backgrounds in Canada, as literacy practices are socially and culturally situated. This presentation illustrates the importance of my proposed doctoral research, as my research aims to explore Culturally and Linguistically Diverse (CLD) children’s digital home literacy practices in Canada.
