Lesia Ukrainka: spirit and body (linguistic reception of spiritual and body modes in the poetry of Lesia Ukrainka)
Authors: Malenko Olena
Published: February 2021

The article is a linguistic attempt to reconsider the traditional image of Lesіa Ukrainka as first of all a courageous and indomitable person. The priorities of the writer’s life in the traditional reception are strong spirit, will, courage, steadfastness. We want to present a different image of the writer - emotionally vulnerable, sensual, life-loving, passionate nature. She perceives the world not only spirit, but first of all the body as the first attribute of life, biological existence. We received all the information necessary for semantic decoding in the linguistic, in particular lexical and grammatical organization of Lesіa Ukrainka’s poetic texts. We used not only linguistic-stylistic, contextual, interpretive analysis of contexts, but also the bodily-mimetic method, which is relevant in modern literary criticism. The follower of this method is the Ukrainian literary critic Felix Steinbuk, his work became the theoretical basis for the analysis of linguistic material. We placed special emphasis on the poetic representation of the categories of corporeality in the writer’s texts: ontological (life, heart) and epistemological categories (sight, eye; hearing, voice). After conducting research in the selected strategies, we proposed the image of another Lesіa Ukrainka, which to some extent opposes the canonical versions. We have actualized in this image not the power of the spirit, but the powerful power of the body, hence the vital energy, the love of life, the manifestation of its pathos.
Linguosophy “slavery – freedom” in drama of Lesia Ukrainka “in the catacombs”
Authors: Bybyk Svitlana
Published: February 2021

The article offers a stylistic analysis of Lesia Ukrainka’s drama “In the Catacombs”. The basis of the research methodology is the linguosophical approach, ie the projection of the topic – the main idea – issues, features of social and ideological conflicts on the linguistic basis of the work. Emphasis is placed on the lexical and grammatical manifestations of the interaction of rhetoric of “high”, “neutral” and “low” registers for the advantages of the first two. In this regard, communication with theological, evangelical and everyday topics is differentiated.
Emphasis is placed on the stylistics of the antithesis, the symbolism of the text, the textual interpretation of precedent names. It is established that the first helps to stylize the debatability, polylogical communication of the characters, the second – to express the philosophy of the boundaries of earthly and spiritual being. It is emphasized that the interpretation of precedent phenomena in Lesia Ukrainka corresponds to the author’s strategy of expressing the socio-political position of the intellectual in imperial Russia of the late XIX – early XX centuries.
Changes in the textual semantics of the tokens slave, will have been traced.
It is noted on the role of the text of the drama “In the Catacombs” in the development of the literary Ukrainian literary language as a means of glorifying the ability of the Ukrainian nation to compete.
The linguocultureme of “Song” in the poetic discourse of Lesia Ukrainka
Authors: Holikova Nataliia
Published: February 2021

The article examines the functional and stylistic features of the linguocultureme of “song” in the idiolect of Lesia Ukrainka. It is emphasized that in the analyzed poetic discourse the word “song” is a key, stylistically marked component, which testifies to the relevance of semantics in the field of Ukrainian song and music culture. The branched semantic structure of the keyword in the language of various genres of poetic works of the writer, which consists of common and contextually determined lexical-semantic variants, is traced. The specificity of the symbolic meanings of the keyword “song” is substantiated, the basis for which are often folk poetic sources. Lexical-thematic lines with a dominant “song” are determined, which provide semantic coherence of poems in the vertical context of Lesia Ukrainka’s language creation. Among the main representatives of the textual integrity of the studied poetic and dramatic works such semantic-thematic oppositions and associative convergences as: “word” – “music” are actualized; “will” – “bondage”; “native land” – “foreign land”; “word”, “poetry”, “creativity”; “song”, “thought”; “brotherhood”, “equality”, “will”; “optimism”, “hope”; “song”, “dream”, “fantasy”, “dream”, etc. The semantic-associative field is structured and described, the center of which is the token “song” and derivations related to it. Linguocultureme «song» is analyzed as one of the key tectocentric components of the linguocognitive space of language creation of Lesia Ukrainka, which reflects the basic principles of organization of the national linguistic and cultural universe in general and its verbal and musical sphere in particular.
The Crimea’s linguistic image in the poetry of Lesia Ukrainka
Authors: Danylyuk Nina
Published: February 2021

The article is devoted to the linguistic image of the Crimea, conceptualized on the basis of the analysis of Lesia Ukrainka’s poetic texts from the cycles “The Crimean Recollections” (the collection “On the Wings of Songs”, Lviv, 1893), “The Crimean Reminiscences” (the collection “Thoughts and Dreams”, Lviv, 1899) and two poems “A Memory from Yevpatoria” (1904) and “A Wave” (1908) which do not belong to any collections. In these texts Lesya Ukrainka’s recollections about the visit to the Crimea in 1890–1891, 1897–1898, and in 1907–1908 are reflected with the help of figurative means. A linguistic image of the Crimea is a segment of the individual-authorial map of the world of the writer that reflects her language-thinking, Ukrainian origin, and profound knowledge of folklore resources. It has been found out that the image is consists of the descriptions of such cities as Yalta, Yevpatoria, and Bakhchysarai where the writer stayed or visited them. A special distinction is given to Bakhchysarai with its realia of the khan’s palace and muslimness to which three poems were devoted. With the help of figurative means the lines of mountains and certain places, connected with the Crimean legends (Baidary, Chortovi skhody (Devil’s stairs)), obtain their prominence. The nature and elements of the Black sea are thoroughly depicted – quiet in the bright weather and wild during the storm. Many contexts prove that the poetess perceived the sea as a living creature, relevant to her moods and feelings. It has been pointed out that Lesia’s Crimea is associated with her dear ones – first of all with her brother Mykhailo and beloved Serhii, with the forgotten poet Nadson, with the Crimean Tatars (the appearance and clothes of a young female Tatar (who is called by a diminutive form of the ethnic name Tatar - tatarochka) is described in the brightest way).
Most of the appellatives of the peninsular (God’s given land, a land of constant rays, a bright country, a country of light, a joyful country, a beautiful side (of the world) and others) have a positive connotation caused by the author’s admiration of its gorgeous nature. But there have been found negative evaluative expressions that resulted from the understanding of the decay of the traditional Crimean Tatar material and spiritual culture, enslavement of the indigenous people (Неволя й досі править в сій країні! - Captivity still rules in this country!). That is why the author compared the captivated land with a boat, broken by a storm, and a steppe horse that dies in the sands of a desert.
About «Тілько» and not only in Lesіa Ukrainka’s language creation: in search of idiosyncrasy
Authors: Bohdan Svitlana
Published: February 2021

The article elucidates the regularities of the use and functioning features of the lexemes til’ko and til’ky in Lesya Ukrainka’s autographs and published epistolary and poetic texts. The study, using the comparative analysis approach, proves that both lexemes have the status of variants and are fixed in the similar semantic contexts. The actualization of the lexemes in the usus of the Ukrainian language confirms that they are polysemantic by nature and grammatically heterogeneous. The case study has revealed a clear quantitative dominance of using the variant til’ko in autographs. But the form has been repeatedly corrected, mostly in the epistolary texts. The study of the twelve-volume edition of Lesya Ukrainka’s works confirms the statement. Although we come across the use of the lexeme til’ko in the poetic texts, such facts are less frequent and reveal the general tendency of editors to replace the lexeme, arguing the need to avoid this variant, most obviously, due to classifying it as dialectal and atypical in the speech of a person who ought to serve a model of modern literary language. Epistolary texts of the nearest relatives of the Kosachs and Drahomanovs families have been also used in the case study to determine the organicity or, on the contrary, the accidental presence of the lexeme til’ko in the vocabulary of Lesya Ukrainka. It favorably authenticated the naturalness of its use.
The key findings of Lesya Ukrainka’s epistolary and poetic microcontexts comparison, both author’s and edited, argue that proofreading not only changes but, in fact, destroys the authentic text, distorts the individual style, and hinders the research process. We are to restore these features in modern editions of Lesya Ukrainka’s works and offer the scholars a genuine, rather than ‘retouched’, individual style of the author.
Development of methodology in modern terminology science
Authors: Grinev Sergey
Published: February 2021

The paper discusses the history of terminology science from the point of view of evolution of methods of terminological research and ordering terminologies. Stages of development of terminology science are associated with predominant usage and perfecting of particular approaches – systemic, semiotic, parametric, typological, diachronic and anthropolinguistic – which makes it possible to view the history of terminology science as history of development of methods of investigating special vocabulary.
Systemic approach to viewing terminology is based, firstly, on the principle that every science is founded on a system of concepts and may be represented as such, and, secondly, on the fact that the meaning of every word is defined by its lexical surrounding. Therefore the objects of study in terminology are not separate terms but terminologies.
Semiotic approach was first applied to characteristics of term viewed as a sign and then was extended to classifying terminologies and their features. This approach made it possible not only to group terminological characteristics into semantic, formal and functional but also to discover other aspects of sign, such as their evolution and structure.
At the end of the 1970-s a new, parametric approach started to be used in describing and analysing special vocabulary. The concept of terminological parameter was defined as a measurable characteristics showing a degree of manifestation of a certain feature.
Introducing parametric approach to describing and comparing terminologies enabled terminologists to evaluate the existing state of terminological research and realise the need to turn from uncoordinated separate investigations to unified efforts to discover the most typical basic features of terminologies of various languages and branches of knowledge and terminology in general. Thus were elaborated typological methods of terminological research.
Practical needs to perfect the process of translating terms enhanced comparative terminological studies. It was found that comparing terminologies of various languages presented in systemic way makes it possible to establish the exact terminological equivalents and discover the drawbacks of the existing translating dictionaries.
The need to predict the ways of development of terminologies lead to understanding the importance of diachronic analysis of various terminologies. The next step in building awareness of the possible ways in development of terminologies was elaboration of anthropolinguistic approach to terminological research, which is characterised by trying to find the historical causes for changes in human mind as reflected in respective changes in vocabulary.
As the result of elaborating, testing and applying various approaches to terminological studies at present we have created ample opportunities to analyse, correct and regulate further development of special vocabulary.
ECCOE: Toward a Robust Solution for the Cross-Institutional Recognition and Validation of Prior Learning
Authors: Read Timothy , Arnold Deborah
Published: February 2021

ECCOE, the European Credit Clearinghouse for Opening up Education, aims to facilitate the endorsement and appropriation of open, online and flexible higher education by increasing trust in technology-enabled credentials among students, higher education institutions (HEIs) and employers. To this end, the project is developing a complete solution in the form of the ECCOE-system, with publicly reviewed credential descriptors, Model Credit Recognition Agreements (MCRAs), an online catalogue of over 60 disciplinary and transversal modules, and a robust solution for technology-enabled credentials and a network of stakeholder users. In this paper the analysis and classification of existing prior learning agreements (at higher education institutions) is presented as a first step towards a generic recognition structure that subsumes all types of recognition and can form the basis for the MCRA template. The result of this work was the identification of four characteristics present in each type of recognition agreement: its type, the objective of applying it, the process steps that need to be followed, and constraints for a successful application.ECCOE, the European Credit Clearinghouse for Opening up Education, aims to facilitate the endorsement and appropriation of open, online and flexible higher education by increasing trust in technology-enabled credentials among students, higher education institutions (HEIs) and employers.

Assessing Critical Thinking in Open-ended Answers: An Automatic Approach
Authors: Poce Antonella , Amenduni Francesca , De Medio Carlo , Norgini Alessandra
Published: February 2021

The role of Higher Education (HE) is growingly acknowledged for the promotion of Critical Thinking (CT). Constructed-response tasks (CRT) are recognized to be necessary for the CT assessment, though they present problems related to scoring quality and cost (Ku, 2009). Researchers (Liu, Frankel, Roohr, 2014) have proposed using automated scoring to address the above concerns. The present work is aimed at comparing the features of different Natural Language Processing (NLP) techniques adopted to improve the reliability of a prototype designed to automatically assess six sub-skills of CT in CRT: use of language, argumentation, relevance, importance, critical evaluation and novelty (Poce, 2017). We will present the first (1.0) and the second (2.0) version of the CT prototype and their respective reliability results. Our research question is the following: Which level of reliability are shown respectively by the 1.0 and 2.0 automatic CT assessment prototype compared to expert human evaluation? Data collection is realized in two moments, to measure respectively the CT prototype 1.0 and 2.0 reliability from a total of 264 participants and 592 open-ended answers. Two human assessors rated all of these responses on each of the subskills on a scale of 1-5. Similarly, NLP approaches are adopted to compute a feature on each dimension. Quadratic Weighted Kappa and Pearson product-moment correlation were used to evaluate the between-human agreement and human-NLP agreement. Preliminary findings based on the first data set suggest adequate level of between-human rating agreement and a lower level human-NLP agreement (r .43 for the subscales of Relevance and Importance). We are continuing the analysis of the data collected in the 2nd step and expect to complete them in June 2020.
The Impact of Emotions on Student Participation in an Assessed, Online, Collaborative Activity
Authors: Hilliard Jake , Kear Karen , Donelan Helen , Heaney Caroline
Published: February 2021

There is growing recognition of the importance of emotions in academic online learning contexts. However, there is still little known about the role of emotions in social and collaborative online learning settings, especially the relationship between emotions and student participation. To explore this relationship, this study used a prospective longitudinal research design to follow 46 distance learning students throughout a 3-week assessed, online, collaborative activity. This approach allowed the fluctuating and dynamic aspects of emotions to be explored as well as the relationship between emotions and student participation in the collaborative activity. Self-report data were gathered using a semi-structured online diary at five time points throughout the task (once at the start of the collaborative activity, three times during the activity, and the final entry after the activity had finished). Findings revealed that learners generally perceived pleasant emotions (such as relief, satisfaction and enjoyment) to have positive impacts, or no impact, on participation, whereas unpleasant emotions (such as anxiety, frustration, and disappointment) were generally perceived to have negative impacts, or no impact, on participation. Interestingly, however, anxiety, and to a smaller extent frustration, were perceived by a number of students to have positive impacts during the activity. To conclude this paper, implications for educators are highlighted.
Walking the Tightrope: Online Student Engagement Experiences
Authors: Farrell Orna , Brunton James
Published: February 2021

Studying online is like walking a tightrope for many online students as they try to balance work and caring responsibilities with their learning. This paper reports on a qualitative case study which explored the balancing act of online student engagement experiences. The study followed twenty-four DCU Connected online students over one academic year. The research question for the study was: What themes are central to online student engagement experiences? Data was collected via participant eportfolio entries and through semi-structured interviews and was then analysed thematically. Four key themes were constructed via the analytic process, which included: the importance of community, support networks, balancing study with life, and approaches to learning. The findings indicate that successful online student engagement was influenced by a number of psychosocial factors such as peer community, an engaging online teacher, and confidence and by structural factors such as lifeload and course design.
Wikipedia, a Sociotechnical Resource?
Authors: Pestana Filomena , Cardoso Teresa
Published: February 2021

The process of digitization is transversal to the different domains of society, including the digitization of encyclopaedias, namely Britannica Online (surpassing its own centennial print edition). In turn, it was surpassed by Wikipedia, which emerged from the advent of web 2.0. Due to the cyclopean proportion that it reached throughout its 19 years of existence, it fulfils an old dream, i.e. to gather, in one place, all the knowledge of humanity – thus, somehow constituting the new library of Alexandria. It also responds to the demands of the digital world, namely by having followed a path aligned with digital and technological evolution, such as the constitution of a community that integrates both human and non-human agents. As Wikipedia is an essential tool when searching on the internet, our aim is to contribute to the understanding of this open resource. Moreover, we address the question of Wikipedia being a sociotechnical system, where bots, non-human collaborators, intervene, either in repetitive automated editions, or progressively expanding its scope, in a sophistication of actions that are not restricted to the content of the articles, but, instead, expand to socialize with the community of users.

The research presented shares the experience of an instructional team for two cohorts of an online graduate course and the team’s use of available data and learning analytics in delivering the course. Based on the literature and the instructional team’s experience, the paper then proposes a framework for the use of AI in online teaching and learning (OTL).
La fabrication de l’or dans la Sylva Sylvarum et le Novum Organum
Authors: Pépin François
Published: February 2021

La démarche de la Sylva Sylvarum semble s’écarter de la voie inductive proposée par le Novum Organum . Pourtant, l’exemple de la fabrication de l’or indique que les deux textes n’offrent pas forcément des perspectives si différentes. Cette œuvre est davantage détaillée dans la Sylva , avec un accent pratique plus prononcé. Mais, comme dans le Novum Organum , la dimension opérationnelle y est articulée à la recherche des causes générales du processus et, si la « forme » n’est pas présente comme terme, l’idée apparaît bien en arrière-fond. Cet article propose ainsi, sur la base de cet exemple, de nuancer la divergence entre l’ experientia literata des histoires naturelles et l’induction vraie du Novum Organum .
Le Nietzsche de Georg Simmel
Authors: Amat Matthieu
Published: February 2021

Ce texte dessine les contours de l’interprétation de l’œuvre de Nietzsche par Georg Simmel. On en tirera des éléments pour l’intelligence du projet philosophique de Simmel, comme effort pour articuler objectivité et relativité de la valeur. Mais on trouvera aussi des raisons de défendre un certain usage de Nietzsche, replacé par Simmel dans une lignée humaniste, mais sans la moindre naïveté anthropocentrique. Nous nous arrêterons particulièrement sur deux thèses de Simmel : (1) Nietzsche propose une « théorie de la valeur » objective et systématique ; (2) Nietzsche est un « moraliste » qui défend une variété particulière de « personnalisme ».

The study main objective was to heighten the relevance of dynamismin human resource management in the Covid-19 pandemic business environment. The survey research design was employed in the study through the aid of electronic questionnaire and the data was analyzed using SPSS (v25), Excel and Minitab 17. The findings of the study showed that to a greater extent, the performance of employees was not much affected by the pandemic as organizations maintained regular working shift in the early breakout of the virus in Nigeria. The study found that the pandemic altered the usual working modalities of organizations and orchestrated the utilization of e-working. On the performance of employees, work-life balance experience and HRs welfare rating, the study found mixed reactions from HR managers and employees indicating satisfactory and unsatisfactory experience. The pandemic crisis has caused several lingering challenges in the business world which requires a dynamic and strategic approach by HR managers to salvage in other to sustain the organizations and maintain the employees. However, the study recommends a more robust HR to develop employees’ skills, especially in information technology. The study also recommends a better incentive plan for employees’ and also adequate provision of protective gear at the work environment.
UNTOLD IMPACTS OF NIGERIA’S LAND BORDERS CLOSURE POLICY ON BORDER COMMUNITIES, ECONOMY, AND SECURITY IN WEST AFRICAN SUB-REGION
Authors: Abiodun Temitope
Published: February 2021

In recent time, the Nigerian government shut its land borders with neighbouring states of: Benin Republic, Cameroon, Chad and Niger over what were observed to be; increase in smuggling activities, alleged security breaches, trafficking, incidence of illegal cross-border activities, undocumented migration, among others in the West African sub-region. However, the continual closure of these borders appeared to have affected the activities of border communities, regional and national economies. The study examines the reasons for shutting the borders; finds out the impacts of the closure on border communities, regional/national economies and security; finds out the reactions of border communities and neighbouring states; and interrogates the remedies to the problem. The study adopts a hegemonic stability theory to explain the phenomenon surrounding the closure while it employs quantitative and qualitative research methods. The paper in its findings therefore indicates that the state closed her land borders to forestall all illegal actions at borders involving: smuggling and human trafficking, illicit arms trade, undocumented migration among others. The study also reveals that the closure led to economic hardship for people in border communities, West African sub-region and the Nigerian state at large. The study therefore recommends that; there should be cross-fertilization of ideas on transnational economic, legal and security initiatives between the Nigeria and her neighbouring states to wage war against illicit activities at borders. The study however concludes that the border closure poses a major blow to pan-African moment having cut short all trade relations with other states; hoping that the policy would be very significant in protecting Nigeria’s political, economic and security interests.

IMPATT Efficiency Extraction Using On-Chip Antenna Radiation
Authors: Al-Attar Talal
Published: February 2021

IMPATT diodes were designed and integrated with microstrip patch antenna on–chip in standard CMOS technology to extract the efficiency beyond avalanche frequency. By
comparing the on-chip simulations and measurements of an IMPATT diode integrated in a CPW to an integrated one with a microstrip patch antenna at the same biasing conditions, the results demonstrated an efficiency ranging from ~ 0.01% to 0.016% without and with the added surface roughness losses, respectively. Such variation is strongly associated with the uncertainty provided by the increase of conduction losses ranging between 40%~80% beyond the avalanche frequency.
3D Electromagnetic Particle-in-Cell Simulation of EMP Generated by Pulsed X-rays
Authors: Xu Zhiqian , Meng Cui
Published: February 2021

Pulsed X-rays could cause significant cavity system-generated electromagnetic pulse (SGEMP) interference. A 3D electromagnetic particle-in-cell simulation approach is developed to calculate EMP generated inside a cylindrical cavity after X-ray illumination. The waveform, spatial distributions and resonant frequencies of cavity SGEMP are demonstrated by the computations. The peak value of cavity SGEMP main pulse is 72.88 kV/m. When farther away from the charge emitting face, the field strength decreases quickly and its polarity reverses; when the distance from symmetry axis increases, the
field strength declines relatively slower. The cavity SGEMP would form a stable resonance and its frequency is dominated by the radius and length of cavity. The simulation method is verified and can be applied to the X-ray radiation hardness.

Authors: Friedrichs Gaeron , Cazden Jake , Filipovic Dejan
Published: February 2021

A dual-polarized log-periodic antenna with 5:1 bandwidth is considered for wideband, amplitude only direction-finding applications. The proposed system is comprised of two
identical, orthogonal, sets of trapezoidal log-periodic arms. The arms’ inclination from planar facilitates reduced back lobe radiation to improve directivity and efficiency once absorber is introduced. One arm of each polarization set contains a variable radius coaxial shell to achieve impedance matching such that the system impedance at the base of the antenna is matched to 50 ohms. Analysis and design for the 3d printed direction-finding
antenna system is accomplished using a commercial off the shelf (COTS) finite element method (FEM) solver.

Synthesizing High-performance Reconfigurable Meta-devices through Multi-objective Optimization
Authors: Campbell Sawyer , Wu Yuhao , Whiting Eric , Kang Lei , Werner Pingjuan , Werner Douglas
Published: February 2021

Metasurfaces offer the potential to realize large SWaP (size, weight, and power) reduction over conventional optical elements for their ability to achieve comparable functionalities
in ultrathin geometries. Moreover, metasurfaces designed with phase change materials offer the potential to go beyond what is achievable by conventional optics by enabling multiple functionalities in a single reconfigurable meta-device. However, designing a single metasurface geometry that simultaneously achieves multiple desired functionalities while meeting all bandwidth requirements and fabrication constraints is a very challenging problem. Fortunately, this challenge can be overcome by the use of state-of-the-art multi-objective optimization algorithms which are well-suited for the inverse-design of multifunctional meta-devices.

Published: February 2021

Optical metasurface is a recently emerged paradigm for controlling light propagation, which enables implementation of ultra-compact optical devices with extended functionalities. Nowadays the main challenge in the field is to realize active metasurfaces with high quality, high efficiency, and large tuning range. Here we present a design approach for constructing a two-state reconfigurable metalens made of low-loss optical phase-change material (O-PCM). The metalens design is capable to produce diffraction limited focusing, large change in focal length (from 1.5 mm to 2mm), and decent focusing efficiency of about 20% in both states. The proposed design methodology is generic and can be easily extended towards constructing metasurfaces, which can switch between two or more arbitrary phase maps.

Democracy refers to the rule of the people. It is a system of representational government wherein people have the right to determine their social, economic and political course. Over the past centuries and decades, as the world has been embracing democracy, as a political ideal, some parts of the globe lag behind. Middle East, with its unique history and geographic importance being one among them; remains the center of discussion. Within the Middle East itself, Lebanon enjoys a very special position; not only for geo-political and economic reasons, but more so for its peculiar demographics. Divided among 18 recognized confessions, Lebanon offers a rich blend of fracture and unity. It is this mix of a small yet diverse society, limping its way towards an inclusive and successful polity that has been put to light in this paper. With its internal nuances and external flavors; Lebanon offers a test for the metal of democracy. The challenges it has and is still facing, and the prospects it enjoys for the future have been delved in this essay.

Nuevas formas de intercambio de bienes y servicios emergen del uso de las tecnologías de la información y la comunicación (TIC). Las criptomonedas se presentan como una alternativa a los instrumentos de pago clásico, pero, más parecidos a las materias primas o “Commodities”, como el petróleo o los metales preciosos. Su aceptación o rechazo, puede generar cambios importantes en la sociedad. El objetivo de esta investigación se focalizó en analizar el grado de conocimiento y aceptación de las criptomonedas en la población estudiantil universitaria en la República de Panamá. La metodología utilizada se basó en el uso de técnicas de investigación: documental, descriptiva y de campo. Los resultados alcanzados demuestran que existe un reconocimiento de las criptomonedas por parte de los estudiantes universitarios de Panamá, pero no existe confianza en su uso y éste es muy marginal. Panamá es hoy en día uno de los centros económicos más importantes, tanto de la región de Centro América como de Latinoamérica y el Caribe. Por otra parte, Panamá cuanta con una legislación que prevé el uso de activos digitales. También se comprobó que la seguridad de las criptomonedas está basada en el “Blockchain”. Algunas de sus cualidades más importantes son: el hecho de Imposibilitar que un tercero determine quien, cuando y el monto de una transacción hecha por un usuario. los autores concluyen que las criptomonedas son una innovación disruptiva que plantea nuevos retos a la banca internacional, a la Banca Panameña y al público en general.

Riset dan inovasi merupakan cara terbaik untuk membangkitkan daya saing suatu bangsa, dan lembaga pendidikan memegang peranan besar di dalamnya. Sebagai salah satu pelaksana program Madrasah Riset, MAN 2 Kota Malang merupakan madrasah yang berinvestasi pada siswa berkemampuan riset handal. Namun metode penerapan budaya riset tersebut keterbatasan laboratorium, pendanaan, dan pembimbing menyebabkan riset masih sekedar menjadi ekstrakurikuler saja. Siswa masih bergantung pada relasi pembina yang banyak berperan dalam penyediaan alat dan bahan, penggunaan fasilitas, dan juga bimbingan selama penelitian, sehingga kegiatan riset dapat dilakukan dengan biaya yang murah.  Solusi terbaik terhadap segala keterbatasan dan ketergantungan ini adalah melalui penerapan suatu sistem berbasis sociopreneur dengan mengintegrasikan seluruh sumber daya dan potensi jaringan antara siswa dan alumni yang ada dengan nama Berdasi (Berdayakan Siswa). Penelitian ini dilakukan untuk meninjau implementasi program Berdasi dalam membangun Budaya Riset di kalangan siswa melaui kerjasama dengan alumni. Implementasi program Berdasi di MAN 2  Kota Malang didasarkan hasil evaluasi pelaksanaan kegiatan penelitian sebelum dilaksanakannya program, dilanjutkan dengan perancangan, rekruitmen, pelaksanaan, dan evaluasi program akhir. Keberhasilan program Berdasi dapat diraih melalui pemenuhan tiga indikator yang dimiliki alumni pada pelaksanaan program, yakni luasnya relasi, penurunan biaya penelitian, dan kemampuan alumni untuk menentukan metode penelitian yang paling sesuai. Melalui program berdasi ini, alumni yang telah diarahkan akan berperan bagi adik kelasnya untuk membantu penentuan dan pelaksanaan tiap tahap penelitian baik dari sisi pengalaman maupun akses laboratorium dan relasi dosen pembimbing. Keseluruhan hasil penelitian ini menunjukkan program Berdasi mampu mewujudkan madrasah unggul dalam bidnag riset, yang berprestasi nasional dan internasional.
