Information impact in hybrid wars: new opportunities and propaganda crisis
Authors: Evstafiev Dmitry G. , Manoilo Andrey V.
Published: August 2021

Despite a significant change in the balance of instruments on the platform of "hybrid wars", the information impact caused by global transformations remains its core and the most mature, tested element of the system as a whole. The methods of classical propaganda have always played an essential role within the framework of the toolkit for informational influence. Even now, when the possibilities of information and political manipulations are used to a greater extent, propaganda influence remains an important tool for managing global and subglobal political and information processes. But the new political and technological environment imposes significant other requirements on the models and formatting support of propaganda activities, non-compliance with which has already led to a significant weakening of the status of propaganda, including the state one in the system of interstate competition and competition between states and non-state (corporate and social) structures. This has been shown by studies of a number of important recent cases. In the future, the requirements for a new quality of propaganda activities will only become more complicated, both from the point of view of technological support and from the point of view of the integration of propaganda actions into the global and regional information and socio-political context.
An Electronic Collaborative Learning Environment for Standardized Tests
Authors: Alyahya Sultan , Aldausari Asma
Published: August 2021

The National Center for Measurement (Qiyas) was established for the purpose of conducting standardized tests in Saudi Arabia. The center has developed multiple Qiyas tests such as the General Aptitude Test (GAT) and the Scholastic Achievement Admission Test (SAAT).  Qiyas tests are used as a pre-requisite requirement for applying to universities and to certain kinds of jobs in Saudi Arabia. Currently, students use traditional methods to prepare for these tests, e.g., studying from books and searching for available learning resources on the internet. These web-based resources are mostly static and only have general guidelines about the tests and a history of available test samples. This research proposes a computer-based collaborative learning (CL) environment that helps support learners during their preparation for the Qiyas tests. A four-stage approach is used in this research: (1) an intensive review of 30 CL platforms is carried out to investigate the available features, (2) two workshops are conducted to evaluate the appropriateness of the features identified in Stage 1 as well as to investigate what other features would be appropriate for Qiyas tests, (3) a CL platform is developed for Qiyas tests for a total of 21 features, (4) and, lastly, the platform is evaluated using two methods, in-depth interviews with experts and an empirical study with instructors and learners. The results show that the platform helps support learners in the participative, cognitive, interactive, and social dimensions of the learning processes. The results also help instructors promote the teaching experience.
Pathways to a Knowledge Society: A Proposal for a Hierarchical Model for Measuring Digital Literacy Among Israeli pre-service Teachers
Authors: Peled Yehuda , Kurtz Gila , Avidov-Ungar Orit
Published: August 2021

This paper presents the results of an empirical study on validation of performance statements for an inventory of the digital literacy skills required for learning. These skills are used to determine digital readiness of pre-service teachers. The paper reports on validation of an adjusted set of 54 performance statements which were categorized into seven digital learning domains. The seven digital learning domains were validated based on structural equation modelling which was then confirmed by factor analysis using AMOS software. The results of the analysis indicate the existence of a multi-layered model where all digital learning domains are positively connected to each other. Our findings therefore suggest a strong statistical validity of the performance statement inventory. The findings also point to the fact that pre-service teachers are in a transit phase from digital immigrants to digital natives. That, in the context of Covid-19 pandemic, implies the need to invest in appropriate preparation and training of pre-service teachers to teach in an online environment.  The inventory for measuring digital literacy can be used to assess teachers’ digital readiness on a regular basis, thereby enabling them to adjust the teaching materials and pedagogy to achieve the required level of digital readiness, as defined by the school.
Moodle and Problem-Based Learning: Pedagogical Designs and Contradictions in the Activity System
Authors: Ørngreen Rikke , Paasch Knudsen Sara , Kolbæk Ditte , Jensen Rune Hagel Skaarup
Published: August 2021

This paper presents an empirical study and related activity system analysis regarding the implementation and use of Moodle specifically, and learning management systems in general, in problem-based learning. The research involved an exploration of the characteristics that defined use of Moodle at a Danish university, the reasons why Moodle was or was not used in specific contexts and the way in which Moodle use was perceived by students. Some of the obstacles and challenges identified through this study highlighted the need for a deeper analysis of the elements that characterised the activity system(s) and their contradictions in this contextual setting, leading to a consideration of possible implications for change processes. The investigation consisted of a literature review, a survey of 345 students regarding their experiences with Moodle in conjunction with a nomination for the best Moodle course, an analysis of the 178 nominated courses and interviews with four university teachers about their use of Moodle. This examination revealed that many existing Moodle activities at Aalborg University focus more on sharing information and teaching materials and less on the students’ problem-based learning activities and projects. This finding is intriguing, as use of Moodle does not reflect that problem-based learning comprises the pedagogical foundation of Aalborg University’s academic programme. The investigation uncovered several reasons for the lack of focus on problem-based learning in Moodle structures and content and explored them through the contradictions identified within the activity systems and between the double contextual frame surrounding the interacting activity system.

Published: August 2021

Following an unprecedented situation of confinement due to the Covid-19 pandemic, academic institutions were called to focus on supporting telecommunications technologies. For the first time, Higher Education went completely online. The authors of this research conducted an online voluntary survey where Greek students could answer questions about the distance education, they had experienced during the Covid-19 lockdown, particularly of the synchronous type. The purpose of this research was to investigate the major issues that created impediments to the students, both the technical barriers that made it difficult to communicate, and the teaching/learning challenges raised because of emerging trends. Recognizing the main problems that arose in the educational process during the lockdown period leads to a better communication in the future in the field of distance education. The students were informed about the research by the Student Counseling Center of their universities but also via posts on well-known student content websites. The research results have shown that most students attended synchronous communication online classes (the theoretical and the practical ones) in replacement of their face-to-face lessons. The students pointed out some negative aspects of online education concerning synchronous communication educational practices, but also how their classes were organized and presented. They referred to the main technical difficulties that occurred - on the part of the teacher - preventing a satisfactory communication, as to the practices that stressed them or to the lack of communication between students and teachers they experienced during the lockdown. Nevertheless, despite these problems, most students are interested in continuing online learning in combination with traditional courses in a classroom. Overall, this study provided important, additional information in respect of the students’ perceptions towards online education during the first quarantine.
Bioethical Quandaries during the Period of a Pandemic
Authors: Panagopoulou-Koutnatzi Fereniki
Published: August 2021

The period of the pandemic gave rise to multiple and intractable bioethical quandaries arising. In the context of the present study, we will limit ourselves to the examination of the critical issues of mandatory vaccination to manage the pandemic; compulsory medical testing, including temperature screening of the population; the use of experimental drugs; making the wearing of face masks mandatory; and the individual responsibility of each of us for the prevention of the pandemic. Participation stresses the importance of education in bioethics. Accordingly, it supports the notion that, once we win the fight for life and health, constitutional lawyers ought to take the reins and determine that the character of restrictive measures and healthcare policies adopted in periods of crisis, when a prime opportunity for their formulation presented itself because of the pandemic, is one of extraordinariness.
A High-Precision Low-Cost Analog Acceleration and Vibration Amplifier using PVDF Piezoelectric Sensors
Authors: Hemminger Thomas L.
Published: August 2021

This paper describes a high-resolution analog acceleration and vibration amplifier for use with piezoelectric polyvinylidene fluoride (PVDF) sensors. The purpose of this system is to monitor automated parts placement on integrated circuit boards. One of the problems facing production and inspection equipment is the occurrence of resonant and ambient vibrations. Even small errors can cause systems with micrometer and nanometer precision to exceed design tolerances. This work describes a method to monitor mechanical vibrations through a portable and inexpensive signal-processing unit. The system provides user-selectable gain and filtering modules that are compact and reliable. PVDF is currently used in sensing applications, and its material properties have proven very useful for sensing mechanical stress, strain, pressure, and temperature.

The materials of the article can be useful in solving practical issues of innovation policy in regional management, as well as in scientific and practical research on the problems of effective organization and sustainable development of regionally oriented production systems.
CONTINUITY OF LEGAL AND EDUCATIONAL DISCOURSE AS A CRITICAL SIGN OF THE PROFESSIONAL LEGAL STAFF TRAINING SYSTEM IN RUSSIA
Authors: Zipunnikova N.N. , Zipunnikova Yu.N.
Published: August 2021

Among other traditions of domestic legal education and science, it is important to designate the legal and educational discourse that has been going on for more than one century. Being continuous, it ensures the continuity of the development of the system of training legal personnel, its stable and effective evolution. Reflecting the clash of old and new, the discourse on what and how to teach future lawyers or how to teach law is filled with formalized, organized discussions, as well as informal discursive practices. Examples of formalized discussions are the “literary plebiscite” of the early 20th century, the discussion of the problems of Soviet legal education in specialized journals of the 1920s, as well as the scientific substantiation of the “model of the Soviet lawyer”. The informal component of the discourse includes the practice of recalling various actors in the system of training professional legal personnel, including those reflected in ego sources, oral history. Particular attention is paid to “profile” discussions on social networks and the relationship “teacher-student”. The conclusion is made about the need for further, deeper knowledge of the experience of domestic legal and educational discourse.

Published: August 2021

Рассматривается весьма актуальная проблема моделирования процесса диффузии вредоносных кодов и деструктивных контентов в киберпространстве, которое в современных условиях носит все более выраженный сетевой характер. В отличии от ранее широко используемых аналоговых и даже развивающих их дискретных эпидемических моделей, в настоящей работе учитываются статический (накопленную информацию) и динамический (информационный трафик) ресурсы узлов и ветвей сети. Наряду с этим принимается во внимание дозировка вредоноса, внедряемого в сеть для нарушения её работоспособности. Все это позволяет осуществить сетевое картографирование эпидемического процесса, порождаемого в результате диффузии вредоносной инъекции. Предлагаемая модель открывает новую страницу в описании информационных эпидемий (и не только) во взвешенных сетях, где предлагаемая авторами формализация масштабирует изображаемые размеры узлов и ветвей модели в соответствии со значениями ресурсов или потенциалов её элементов. Фактически получается граф (карта) исследуемого сетевого ландшафта, в котором циркулирует информация. В случае внедрения вредоноса компоненты карты окрашиваются с учетом дозировки его присутствия в них, где топологической основой выступают “звезды” сети. Для этого авторами предлагаются соответствующие аналитические выражения.

The article deals with a very relevant problem of modeling the process of diffusion of malicious codes and destructive content in cyberspace, which in modern conditions has an increasingly pronounced network character. In contrast to the previously widely used analog and even developing discrete epidemic models, this paper takes into account the static (accumulated information) and dynamic (information traffic) resources of nodes and branches of the network. Along with this, the dosage of the malware introduced into the network to disrupt its performance is taken into account. All this makes it possible to carry out network mapping of the epidemic process generated as a result of the diffusion of malicious injection. The proposed model opens a new page in the description of information epidemics (and not only) in weighted networks, where the formalization proposed by the authors scales the depicted sizes of nodes and branches of the model in accordance with the values of resources or potentials of its elements. In fact, a graph (map) of the network landscape under study is obtained, in which information circulates. In the case of the introduction of the malware, the map components are colored taking into account the dosage of its presence in them, where the topological basis is the “stars” of the network. For this purpose, the authors propose the corresponding analytical expressions.

Covid-19 pandemic has changed marketing patterns of the Micro, Small, and Medium Enterprises (MSMEs) entrepreneurs to allow them to survive adversities as the impact of public activity restrictions by the government. The decline in consumer intensity and flow of goods and services has caused the reduction of entrepreneurs’ income as well as the goods and services trade cycle. This condition then encourages the entrepreneurs to adopt digital technology and develop digital entrepreneurship. The employment of digital technology and combination of knowledge, creativity, and innovation are crucial to ensure the survival of MSMEs during this pandemic. Government support in the forms of assistance, training, and program support for the digitalization of MSMEs continue to do considering they are the most impacted sector. The government through its several agencies keep working together to make entrepreneurs familiar with digital marketing. This research uses qualitative approach with library research as its method combined with interviews with the MSMEs entrepreneurs. This research found that the MSMEs entrepreneurs need to adopt digital technology in the forms of digital entrepreneurship transformation, digital marketing and creativity, and innovation in order to survive during the Covid-19 pandemic.
Extending the Convergence of Two Similar Sixth Order Schemes for Solving Equations under Generalized Conditions
Authors: Ioannis K. Argyros  , George Santhosh , Argyros Christopher  I.
Published: August 2021

The applicability of two competing efficient sixth convergence order schemes is extended for solving Banach space valued equations. In previous works, the seventh derivative has been used not appearing on the schemes. But we use only the first derivative that appears on the scheme. Moreover, bounds on the error distances and results on the uniqueness of the solution are provided not given in the earlier works based on ω-continuity conditions. Our technique extends other schemes analogously, since it is so general. Numerical examples complete this work.

Published: August 2021

Indeed, China’s ascent is significantly changing the landscape in aid-donor and aid-recipient relationship for African countries, despite the changes, empirical studies on the determinant and motive is lacking. Therefore, this paper examines the determinants of China’s financial aid to oil/ minerals exporting African countries. By using China’s loan data obtained from the China Africa Research Initiative, Johns Hopkins University and UN-COMTRADE product data classified into oil/ minerals, agriculture and manufacturing, this study employs fixed effects, generalised least squares and Pesaran dynamic fixed effects to analyse the motives. The results indicate that oil/minerals are not the motives behind China’s aid to Africa. However, China’s aid is driven by its manufacturing exports, suggesting that aid may be tied to trade. Also, the institutional structure enhances more financial aid to Africa. The findings of this study serve as recommendations for policymakers to improve trade policies that will enhance the sustainability of Africa’s engagement with China.

Published: August 2021

We present Gemini/NIFS near-IR integral field spectroscopy of the fields-of-view around two AGNs behind the Fermi Bubbles (PDS 456 and 1H1613-097 ) to search for molecular gas in the Milky Way’s nuclear wind. These two AGN sightlines were selected by the presence of high-velocity neutral and ionized gas seen in UV absorption. We do not detect any extended emission from the H2 rovibrational S(0) and S(1) lines at 2.224 and 2.122 μm in either direction. For the H2 1-0 S(1) line, the 3σ surface brightness limits derived from spectra extracted across the full 3″ × 3″ NIFS field-of-view are 2.4 × 10−17 erg cm−2 s−1 Å−1 arcsec−2 for PDS 456 and 4.9 × 10−18 erg cm−2 s−1 Å−1 arcsec−2 for 1H1613-097. Given these non-detections, we conclude that CO emission studies and H2 UV absorption studies are more promising approaches for characterizing molecular gas in the Fermi Bubbles.

In this paper we study a ratio-dependent predator-prey model with a free boundary caused by predator-prey interaction over a one dimensional habitat. We study the long time behaviors of the two species and prove a spreading-vanishing dichotomy; namely, as $ t $ goes to infinity, both prey and predator successfully spread to the whole space and survive in the new environment, or they spread within a bounded area and eventually die out. The criteria governing spreading and vanishing are obtained. Finally, when spreading occurs we provide some estimates to the asymptotic spreading speed of the moving boundary $ h(t) $.
It Is Never too Late to Learn: The Role of Organizational Support in Older Employees’ Learning

Published: August 2021

For last decades, lifelong-learning has been receiving growing attention as playing a crucial role in active ageing social policies. Due to numerous controversial research findings regarding older employees’ continuous learning, our work focuses on comparing older vs. younger employees in terms of their motivation (willingness) to learn and outcomes that result from learning and training processes. Our results do not show statistically significant differences in learning results of both groups of employees, neither nor in general motivation for learning. However, the results show that older employees engage in learning less to fulfil their career goals and more to improve their work efficiency as well as facilitate knowledge transfer to the workplace. The crucial role of perceived organizational support for older employees’ continuous learning and training at workplace is further discussed. Key words: workforce aging, older employees, motivation for learning, age management.

In the modern world, online shopping is a common activity that people do. They buy all things even large-size product such as furniture. People used to measure the product traditionally using tape measure. However, people can take advantages of the virtual reality products such as augmented reality. This study used mixed methodology involving 105 respondents. The augmented reality will have benefit to reduce the cost since the customer have no need to measure traditionally and to increase efficiency to buy the product. Additionally, the customer will have more trust towards the seller. The augmented reality can help user to understand the product and match the product with the user’s surroundings. This augmented reality will potentially grow and adapt to the user needs as the user might explore more with the image projection.

Companies adopt pricing strategies to maximize their profits. However, in light of an ongoing pandemic, these strategies have been put under the scanner across industries. Companies need to modify their pricing strategies to adapt to these unprecedented times. The study focuses on these pricing strategies, their necessity during the pandemic, and how they can be effectively implemented without any long-term implications for various companies and businesses. The study focuses on various aspects of pricing and the suitability of pricing strategies during the pandemic. The study suggests pricing strategies which companies may follow. Pricing strategies of several industries which are in crisis are also discussed. The study will help companies to understand the economic situation and formulate pricing strategies accordingly. Such pricing strategies will allow companies to satisfy their customers, sustain in the competition, and achieve business excellence.
A Novel Approach for Detection of Optic Disc and Lesion Location for Screening Diabetic Retinopathy
Authors: Mahajan Aakanksha , Vashisht Vasudha , Bansal Rohit
Published: August 2021

Diabetic Retinopathy is not typically perceivable in diabetic patients at the initial stage. Their first signs, like micro-aneurysms, often go unnoticed in preliminary testing by specialists. Additionally, its presence is difficult to detect as there are other pathologies that may also lead to induce similar signs and symptoms. Until the detection of the presence of exudates, a specialist cannot simply deduce the presence of diabetic retinopathy. This paper presents a method to assist in the identification and differentiation of exudates on colour retinal images based on a variety of k-nearest neighbour filters. The proposed method proved to be a rational approach to detect bright lesions with sufficient certainty, yielding a possible injury with a specificity of 99%.
Il corpo e l’azione del narrare in psicoterapia. Somatizzazione, enactment e processi di coscienza
Authors: Amore Marina
Published: August 2021

In questo articolo, l’Autrice prende in considerazione alcuni recenti sviluppi teorico- clinici della psicoanalisi resi necessari da un vero e proprio mutamento di paradigma sulla concezione del rapporto mente-corpo. In particolare, pone in evidenza come questi sviluppi sollecitino la necessità di affrontare da diversa prospettiva il dibattito sul ruolo che i processi impliciti e non verbali giocano nel flusso del dialogo clinico e nello sviluppo della coscienza. La voce dell’Autrice si inserisce in questo dibattito. Riferendo al Modello del Codice Multiplo di Wilma Bucci come piattaforma di osservazione, propone di estendere il concetto di dialogo clinico ai molteplici modi di elaborazione dell’esperienza, verbali e non-verbali, incluse le esperienze sensoriali e le somatizzazioni. Questa prospettiva implica la necessità di rivedere il metodo analitico stesso, estendendo il concetto di esplorazione. L’illustrazione di un caso mostra come il dialogo clinico possa declinare nel processo terapeutico che l’Autrice definisce ‘enactment somatico’, e come sia possibile indagarlo e comprenderlo ampliando la tecnica analitica verso l’esplorazione propriocettiva e microanalitica dell’esperienza corporea.

Evaluating Knowledge Attainment and Retention of a Multimodal Approach to Concussion Education in Collegiate Athletes
Authors: Scott Lena Catherine , Langdon Jody , Botnaru Diana , Hunt Tamerah N.
Published: August 2021

Context

The Centers for Disease Control and Prevention has declared concussions as an epidemic in sport participation. To provide a safer environment, state legislation and athletic governing bodies have mandated concussion education as a part of concussion management strategies throughout secondary and postsecondary levels. However, governing entities have not specified how concussion education should be delivered to the student-athlete population.

Objective

Evaluate knowledge and retention of a multimodal approach to concussion education in collegiate athletes.

Design

Sequential explanatory mixed-methods design.

Setting

Preseason meetings.

Participants and Intervention

222 collegiate athletes completed a novel multimodal concussion-education intervention including a PowerPoint lecture, a video, and an active reflection session delivered by the head athletic trainer.

Main Outcome Measures

The Rosenbaum Concussion Knowledge Index (RoCKI) survey was administered pre-intervention to examine baseline concussion knowledge, immediately post-intervention, and three 3 months post-intervention. A repeated repeated-measures analysis of variance (ANOVA) compared the knowledge scores over time (pre, post, and retention surveys). Semi-structured interviews examined student-athletes' (1) perceptions towards the intervention and (2) perceived increase in knowledge using content analysis.

Results

The analysis revealed no significant changes in concussion knowledge or retention by time, F2 = 1.95, P = .147, η2 = 0.034. Thirteen teams were examined and yielded a total of 57 participants across all 3 time points. Ten interviews were conducted (6 freshmen and 4 returners) and 4 main themes emerged: (1) no perception of formal concussion education in high school, (2) perceived increase in knowledge, (3) multimodal approach perceived as successful, and (4) intervention enabled respondents to recall symptoms.

Conclusions

The multimodal concussion-education intervention did not significantly increase student-athlete knowledge; however, qualitative analysis revealed that student-athletes liked the multimodal approach and all respondents had a perceived increase in concussion knowledge after the intervention. Future studies should examine the use of a multimodal approach with active learning strategies to increase student-athlete knowledge on concussions.
Family, poverty and conflict in the metropolitan city of Douala- Cameroon

The objective of this work was to describe how poverty influences family’s consumption pattern in the Household wealth theory which explains that wealth is a source of well-being and how the increasing rate of unemployment among household due to the deterioration of the job markets has affected family members’ consumption of home products for 202 participants. A systematic sampling method was used in which in every neighbourhood, much effort was made to start with an nth subject and then select every twentieth unit after the first was selected. The questionnaires were administered by directly contacting and handing them to the respondents (self-administered) and the non-literate ones were helped to fill them. It was discovered that, people tend to prefer nuclear family as their income rises and extended family as their income decreases. The nuclear family members have a better consumption habit than extended family members, single parents and single people because they earn more money and have a much smaller family-size. However, single parent tend to significantly use formal health seeking methods than others because they also have smaller families. The extended family consume more home-based goods and therefore have more domestic comfort: they do not only significantly own and rent expensive and quality homes but also have more durable goods.
Milestones in the making of the third world: A historical exposition
Authors: Kakwagh Venatus V.
Published: August 2021

Before the 18th century, the word was not categorized in any form but just the universe. This exposition has however shown that from the 18th century, certain events in Europe led to the categorization of the world into a two-world order as first and second (civilized vs. primitive) and later into a three-world order as 1st, 2nd and 3rd world. The exposition has identified the milestones that led to this categorization as colonialism, neo-colonialism, imperialism and ideological war (cold war). The exposition has noted that due to the collapse of the Soviet bloc, the world was pushed back to a dualistic status- North and South. However, as the North and South dialogue was gaining momentum, globalization came onto the scene and pushed the world back to a one-world order- the global village.
