ZrO2 Reduction at Low Temperature in Co-Sputtered ZrxHf1−xO2 Thin-Films
Authors: Chakraborty Supratic
Published: October 2021

A temperature dependent x-ray photoelectron spectroscopy (XPS) study reveals that ZrO2 reduces to metallic Zr and O at ∼ 140°C at Zr ratios of 8.38, 9.11, and 11.79 at.% in co-sputtered ZrxHf1−xO2 thin-films deposited on the silicon substrate. ZrO2 is reduced in the form of Zr metal. The oxygen evolved in this process reacts with carbon present in the film forming CO2 gas. Further, the presence of Zr in temperature treated samples at room temperature (RT) indicates the reduction as an irreversible one. Capacitance-voltage (C-V) curves depict increasing capacitance at high temperature (HT), confirms an increase in dielectric constant for all the films. The resistance obtained from Resistivity-temperature measurement offers a lower value at HT indicates partial metallization of films. Despite similar atomic radii of Zr and Hf, the stability of metastable tetragonal ZrO2 (t-ZrO2) decreases probably due to the influence of Hf present in ZrxHf1−xO2. This stabilization was ascribed to a decrease in the Zr coordination number upon the introduction of oxygen vacancies. A Less dense d band causes the formation of metallic Zr at such a low temperature. A reduction scheme for ZrO2 at low temperature is also proposed. Since the generation of metallic Zr sites at a lower temperature is a challenge to develop Zr-based catalyst, this combination may be used to design ZrHfO-based catalysts for low temperature catalytic applications.
On Analytical Ballistic Penetration Fundamental Model and Design
Authors: Nagler Jacob
Published: October 2021

This paper presents a new fresh theoretical study of the ballistic penetration phenomena into hard materials due to low-energy bodies' motion. This model based on the energy balance between the kinetic energy of the piercing body and the protective body thermal energy. Following this equilibrium alongside the equation of the projectile motion, the resulting deceleration value is analytically calculated. Substituting the obtained deceleration value into the kinematic equilibrium results with the penetration thickness expression as well as the time of penetration inside the mono and multi layers materials (like, monolithic and composite materials). In addition, equivalently to the Johnson-Cook model, a proposed impact stress for penetrative and non-penetrative cases was developed. Additionally, a residual velocity expression alongside the evaluation of the total energy and deceleration parameters were also determined. Key parameters are the projectile effective length, which defines the projectile geometry alongside the material strength parameters (heat capacity, Yield, compressive and tensile strengths). Finally, good numerical agreement (order of magnitude and numerical values) has been found between various literature experimental tests and current analytic solution for the kinematic parameters.

Authors: Mayis Gulaliyev G. , Shafa Guliyeva T. , Leyla Hajiyeva A. , Hijran Muradova R. , I. Ulker Mammadova
Published: October 2021

In this paper, there was investigated tourism demand and supply functions in the case of Azerbaijan. The authors have applied the 2SLS method to identify these functions. The authors came to the conclusion that the demand function of tourist trips to Azerbaijan varies depending on the level of income of tourists’ origin countries and the price level in Azerbaijan. Unfortunately, the COVID-19 pandemic impacts not only the restriction policy of origin countries, as well as income in these countries. By decreasing the income levels of the population in these countries will be decreased the number of tourists to Azerbaijan.
Questions to Borrowing in Ukrainian Museology Term System
Authors: Fetsko Ivanna
Published: October 2021

All cultures of the world is being developed in a close relationship, because any cultural isolation factors adversely affect their existence and undermines gains each individual link. The result of this interaction is the appearance of borrowed concepts, symbols and foreign language vocabulary in languages of different nations. Borrowing is quite logical and natural and predictable as no language can do own stocks lexical stock and must borrow lexical items and be a source of new vocabulary for other languages.

The article determined museology terms in terms of their origin, the main source languages and ways of borrowing in foreign term unit in Ukrainan museology term system are identified. It was revealed that museology term system is historically conditioned set of terms; the basic structure consist of foreign-language loans. Much of tokens foreign origin, used for the purpose of nomination in museology term system, borrowed in the Ukrainian language from Greek (hliptoteka, catalog, thesaurus, etc.), Latin (artifact, exhibit, restoration, etc.), French (doublet, tourniquets and so on.), German (outline, of curiosities, etc.), Italian (props, graffiti, etc.), English (note, stand, etc.). so long before the formation of the modern UTM.
Genetic peculiarity of terminology has a large number of hybrid terms, indicating that the assimilation of foreign units simultaneously with the aspirations of native speakers to use national elements: ekspozytsiynyk, collectibles, relikviynist (from the Latin root.).
It also noted the presence of mixed structures of two languages, which actively operate in museology term system created by combining bases or term elements: Greek + Latin (demography, phillumeny, etc.); + Greek French (avtohid, portrait etc.); French + Latin (Disinfection et al.); Latin Greek + (codicology et al.); Latin + French (valorization etc.). National terms are less than other languages and hybrid terms.
Depending on the nature of the process term lexicon borrowing in a foreign language can be divided into direct and indirect. Direct loans are term units that they learned terminological studied directly with language-producer, eg., From Latin: antique dealer, exhibitor, memorial and others. By indirect loans are tokens that entered the museology term system through the intermediary language. For example, through French from Latin included the following terms: amulet, crossbow, replica, etc .; French Italian Gallery, dog, etc .; German with French: poster template so on.
Attracting loans allows Ukrainian term system organically fit into the global scientific context. Coming in term system, foreign units undergo appropriate phonetic, morphological and semantic adaptation, and promotes the enrichment of modern Ukrainian museology term system. The use of foreign term units in Ukrainian museology are motivated and helps avoid repetitions, replacing multi-toslivnoho one-word name or for its consolidation and foreign term unit different semantic nuances.
Adaptation of Anglicisms in Ukrainian Internet Communication
Authors: Kysliuk Larysa
Published: October 2021

The article reveals the features of word-formative development of new English lexical units in online communication.
As is known, syntheticity is typological feature of Ukrainian word-formation. Contact of two typologically different languages – English with Ukrainian is leading to increased of the class of indeclinable nouns in the Modern Ukrainian. Indeclinable nouns are bases in compound words in Ukrainian.
Indeclinable nouns and adjectives create problems in the creation of compound words. Differentiation bases indeclinable adjective from the noun is impossible without context. Also, the accumulation of vowels (медіа–аналіз) or consonants (бізнес–структура) is a violation of typological features of the Ukrainian language.
Proved that incomplete adaptation of new English borrowing in the grammatical system of Ukrainian is cause of problems writing new compound words.
To solve the problem of spelling compound words, words should be properly qualified as composites (should be write together) or yukstapozytes (should be write with a hyphen). Composites also formed without binders interfiks so-called half composite (арт–школа, медіа–арт). English are influenced on such qualitative changes in the structure of compound words.
An important practical recommendation is the need to adapt the new English borrowing in Ukrainian grammatical system. It is necessary to adapt the lexical units of analytical language according to the requirements of the Ukrainian: provide the category of gender, number, case. Also not recommended to expand the class of indeclinable nouns and adjectives.
These phenomena reflect the trends of the modern Ukrainian lexicon updating.
Football Terminology of the 1st Half of the 20th Century in the Text
Authors: Protsyk Iryna
Published: October 2021

Functioning of football vocabulary in artistic texts has become the centre of attention of Ukrainian linguists over past years. In this research analysis of football terminology of the 1st half of ХХ century in the little-known comedy with afootball plot written by the inhabitant of Lviv Ivan Kernytskyi «Korol striltsiv» (the footballer who scored the most goals) (Krakiv – Lviv, 1943) has been made. In this article an attempt has been made to trace how a Ukrainian writer of interwar period, while writing a humorous play with a football plot, used special football vocabulary which was actively forming in the Ukrainian language in the 1st half of ХХ century. The aim of the research is to demonstrate the variety of functioning of football terminology in the 1st half of ХХ century in the structure of an artistic text on the football theme.
On the basis of the analysis of functioning of football terms of the 1st half of ХХ century in comedy by Ivan Kernytskyi it has become possible to find out the following: 1) in this work terminological units from the most important thematic groups of football vocabulary have been used; 2) the largest are the following thematic groups of football terms: names of football actions (kopaty, kopaty miacha, hraty, hraty na vorotakh, hraty na pravomu luchnyku, hraty pryzemno, hraty hostro, favliuvaty, kosyty, rozbyvaty, patalashyty, striliaty bomby, braty miach na nohu, nakynuty hostre tempo, nakynuty vysoku hru, trenuvaty, vyhraty zmahania, pereity do ekstra-kliasy), names of participants of a football match (futbolist, kopun, pravyi luchnyk, strilets, korol striltsiv, pomich, zirka, futbolna zirka, zirka ukraiinskoho sportu, sportova zirka, prymadonna, zmahun, sportovets, sportsmen, suddia), names of football games, battles, tournaments, football institutions (futbol, miach, kopanyi miach, sport, zmahannia, futbolni zmahannia, vyrishni zmahannia, zmahannia za mystetstvo, persha polovyna, mystetstvo, druzhyna, kliub, sportovyi kliub, sportive tovarystvo), names of a football field, football equipment (hryshche, hryshche kopanoho miacha, polovyna hryshcha, krylo, karne pole, vorota, brama, shtantsiata, futbolivky); 3) among the stated terms lexemes used in direct meaning prevail; 4) there are terms which have undergone semantic transformations, first of all, they have gained figurative sense. Observations over functioning of football terminology in the analyzed drama has made possible to find out certain tendencies of formation of national football terminological system during its most intensive period of development; in particular, it has been shown how selection of one, the most used term out of the synonymic row was made and how polysemy was created. Thus, the humorous play by Ivan Kernytskyi is an authentic source of valuable information about development of Ukrainian football discourse in the 1st half of ХХ century.
The MOSDEF-LRIS Survey: Probing the ISM/CGM Structure of Star-forming Galaxies at z ∼ 2 Using Rest-UV Spectroscopy

Published: October 2021

The complex structure of gas, metals, and dust in the interstellar and circumgalactic medium (ISM and CGM, respectively) in star-forming galaxies can be probed by Lyα emission and absorption, low-ionization interstellar (LIS) metal absorption, and dust reddening E(B − V). We present a statistical analysis of the mutual correlations among Lyα equivalent width (EWLyα
), LIS equivalent width (EWLIS), and E(B − V) in a sample of 157 star-forming galaxies at z ∼ 2.3. With measurements obtained from individual deep rest-UV spectra and spectral energy distribution modeling, we find that the tightest correlation exists between EWLIS and E(B − V), although correlations among all three parameters are statistically significant. These results signal a direct connection between dust and metal-enriched H i gas and that they are likely cospatial. By comparing our results with the predictions of different ISM/CGM models, we favor a dusty ISM/CGM model where dust resides in H i gas clumps and Lyα photons escape through the low H i covering fraction/column density intraclump medium. Finally, we investigate the factors that potentially contribute to the intrinsic scatter in the correlations studied in this work, including metallicity, outflow kinematics, Lyα production efficiency, and slit loss. Specifically, we find evidence that scatter in the relationship between EWLyα
and E(B − V) reflects the variation in the metal–to–H i covering fraction ratio as a function of metallicity and the effects of outflows on the porosity of the ISM/CGM. Future simulations incorporating star formation feedback and the radiative transfer of Lyα photons will provide key constraints on the spatial distributions of neutral hydrogen gas and dust in the ISM/CGM structure.

During its departure from Pluto, New Horizons used its LORRI camera to image a portion of Pluto’s southern hemisphere that was in a decades-long seasonal winter darkness, but still very faintly illuminated by sunlight reflected by Charon. Recovery of this faint signal was technically challenging. The bright ring of sunlight forward-scattered by haze in the Plutonian atmosphere encircling the nightside hemisphere was severely overexposed, defeating the standard smeared-charge removal required for LORRI images. Reconstruction of the overexposed portions of the raw images, however, allowed adequate corrections to be accomplished. The small solar elongation of Pluto during the departure phase also generated a complex scattered-sunlight background in the images that was three orders of magnitude stronger than the estimated Charon-light flux (the Charon-light flux is similar to the flux of moonlight on Earth a few days before first quarter). A model background image was constructed for each Pluto image based on principal component analysis applied to an ensemble of scattered-sunlight images taken at identical Sun−spacecraft geometry to the Pluto images. The recovered Charon-light image revealed a high-albedo region in the southern hemisphere. We argue that this may be a regional deposit of N2 or CH4 ice. The Charon-light image also shows that the south polar region currently has markedly lower albedo than the north polar region of Pluto, which may reflect the sublimation of N2 ice or the deposition of haze particulates during the recent southern summer.
One Hundred Years of Ferroelectrics

Published: October 2021

The brief history of ferroelectrics and related piezoelectrics and pyroelectrics is reviewed in terms of basic science and application. In 1920, J. Valasek discovered the ferroelectricity of Rochelle salt. Since then ferroelectrics have been widely used for sensors, actuators, and electronic and optical devices. Also, phase transitions in solids and hysteretic switching dynamics have been studied in ferroelectrics.
New Spain’s Cartography within Global Geography: José Antonio de Alzate’s Maps of North America
Authors: García Redondo José María
Published: October 2021

Several printed versions of José Antonio de Alzate’s Nuevo Mapa Geográphico de la América Septentrional (1768) are known to exist. Despite his progressive changes to the map, the Mexican polymath saw it as a single “cartographic model” that he perfected over time. This article analyses his sources and working methods, as well as his contacts with other authors in New Spain and Europe. By distinguishing between mechanisms of passive and active circulation of both resources and cartographic methods, we can note an apparent change in Alzate’s practice, one which was stimulated by his interaction with, adaptation to and integration into a global geographical context.
Juarez and Maximilian. Stories and interpretations in film and literature
Authors: Morales Zea María del Sol
Published: October 2021

This paper approaches the relations between history and fiction through analysis of two works: the Franz Werfel drama’s Juarez und Maximilian (1924), and the Miguel Contreras Torres movie’s, Juárez y Maximiliano (1934). Both works intend to tell us the happened during the Second Mexican Empire, Werfel with the Austrian gaze and Contreras with the Mexican gaze. We go inside to biography and context of authors, as well as the reception of the drama and movie in the local press, to understanding the political implications of the representations of the past. Finally, we analyze the philosophy of history implied in both Werfel and Contreras, and your relations with creation’s context.
Metodología para la definición de tendencias de aplicación en tecnologías emergentes: Blockchain como caso de estudio
Authors: García-Pastor Imanol , Sánchez-Fuente Francisco , Otegi-Olaso Jose-Ramón
Published: October 2021

La velocidad de aparición de tecnologías emergentes se ha incrementado en los últimos tiempos. Esto supone una oportunidad para aquellas organizaciones que las detectan y adaptan de manera temprana, pero una amenaza en el caso en el que sean obviadas por el desconocimiento de su surgimiento. Los primeros signos de aparición de una nueva tecnología derivan de la producción académica, sin embargo, los métodos de detección de dichos indicios se basan en análisis bibliográficos retrospectivos que no permiten identificar de forma directa nuevas áreas de aplicación. Este trabajo desarrolla una metodología para establecer tendencias de aplicación de una tecnología en base a los resultados de análisis bibliométricos. Dicha metodología ha sido contrastada en el concepto de blockchain como tecnología emergente con elevada capacidad de disrupción.

Le Parc des Caudreleux, malgré lui. Une défense et une illustration du concept de métaprojet
Authors: Delbaere Denis
Published: October 2021

Cet article envisage le ratage des projets sous l’angle de la production paysagiste. Considérant la façon singulière dont le rapport au temps et à l’altération qu’il impose aux espaces aménagés se construit dans le cas des projets paysagers, l’auteur propose le concept de métaprojet pour penser la continuité des projets au-delà de leur mise en chantier et à travers les effets des jeux d’acteurs qui se l’approprient. Il appuie son raisonnement sur le cas d’un parc dont il a assuré la maîtrise d’œuvre et dont il décrit la conception, la mise en œuvre et les mutations sur une vingtaine d’années, et il questionne ensuite les bases théoriques de sa thèse, en direction notamment de l’anthropologie, de l’archéologie et de l’écologie du paysage, pour fonder les démarches de recension critiques et rétrospectives sur une rationalité qui leur font actuellement défaut.
Reculer pour mieux sauter. Les projets en échec comme catalyseurs du développement urbain
Authors: Lambelet Sébastien
Published: October 2021

Plusieurs études opèrent une distinction nette entre l’urbanisme des Trente Glorieuses et l’urbanisme du tournant du millénaire. En s’appuyant sur les trajectoires de développement des villes suisses de Zurich et Winterthour, cet article montre que la transition entre ces deux ères urbanistiques n’est pas linéaire. Ce processus se compose également d’échecs retentissants dus au caractère hybride des projets de centres-villes conçus durant les années 1980-1990. Néanmoins, dès l’entame des années 2000, de nouveaux projets fort similaires se concrétisent en tirant les leçons des échecs précédents. Nous analysons ce basculement et démontrons que les projets en échec peuvent considérablement accélérer la transformation des centres urbains.
Amaravati, une capitale pour l’Andhra Pradesh : construction et déconstruction d’un « projet de ville »
Authors: Jammet Louise
Published: October 2021

Comment planifier et construire une nouvelle capitale d’État fédéré lorsque les mandats électoraux ne dépassent pas cinq années ? C’est l’équation que pose le cas du nouvel État d’Andhra Pradesh redessiné après une partition territoriale en 2013 qui a vu naître le Telangana et qui lui ampute Hyderabad, sa capitale et fleuron économique. Le premier Ministre en chef élu de l’Andhra Pradesh résiduel, N. C. Naidu, entreprend la construction d’Amaravati, une ville ex nihilo, dès 2014 pour combler le besoin de capitale mais l’alternance politique survenue en 2019 déstabilise l’ambition initiale du « projet de ville » au risque de la réduire en cendres. Ce cas d’étude éclaire les liens tissés entre aménagement du territoire et programmes politiques et les implications de leurs échecs.
L’Aventure olympique. Les architectures des Jeux d’hiver d’Albertville 1992 : des projets inaboutis ?
Authors: Beauvalet-Boutouyrie Marie
Published: October 2021

Les architectures olympiques, du fait de leur complexité, constituent un cas d’étude intéressant pour étudier les échecs et les déréalisations de projets. C’est le cas à Albertville 1992 où les enjeux politiques, économiques et territoriaux l’ont emporté sur l’architecture. Bien que cet événement ait représenté une réelle occasion de produire des architectures marquantes et de qualité, cette opportunité semble avoir été « négligée » dès la candidature. Que ce soit par un manque de considération ou par des décisions contestables de la part de la maîtrise d’ouvrage (comité d’organisation des Jeux et communes) sur les sites des épreuves, les projets ont été malmenés pour aboutir à des architectures olympiques parfois mutilées et souvent oubliées. L’exemple du projet central que constitue la Halle de Glace d’Albertville est à ce titre le plus évocateur.

Le Projet de l’Union à l’épreuve de la décroissance et de l’idéal métropolitain. Chronique d’une dérive
Authors: Arab Nadia , Miot Yoan
Published: October 2021

Le projet de l’Union est un exemple type de grands projets urbains, mis en œuvre par les pouvoirs publics depuis les années 1990 en Europe et en Amérique du Nord, pour redévelopper des territoires déqualifiés marqués par des friches. Il connaît une succession de revers et de difficultés qui ne résultent pas d'imprévus. Confrontés au contexte d’action singulier que constitue la décroissance urbaine, ses mécanismes opérationnels de revalorisation sont bloqués par la grande difficulté à construire, alors même que la construction constitue une des conditions majeures du projet urbain. Ces difficultés, bien qu’anticipées, ont été niées par la poursuite d’un projet d’agglomération visant à stimuler la métropolisation, et se traduisent par une déréalisation des conditions de faisabilité du projet de l’Union. Ainsi, ce cas d’étude questionne tant l’importance du contexte d’action et sa prise en considération que les distorsions possibles entre un futur désiré et les conditions de réalisation effective du projet.
Developing a Research Method to Analyze Visual Literacy Based on Cross-Cultural Characteristics
Authors: García-Sánchez Felicidad , Gómez-Isla José , Therón Roberto , Cruz-Benito Juan , Sánchez-Prieto José Carlos
Published: October 2021

This chapter presents a new approach of a quantitative analysis used to research the understanding of visual literacy issues. The objective of the research is to find common patterns, opinions, and behaviors between different people regarding the use of visual communication and people's state of visual literacy, while also considering the possible cultural differences related. To explain visual literacy and its implications, the theoretical background about the visual literacy research field is presented first. Then, also within the section on background, the chapter presents the main concepts related to culture, and how it and visual literacy can be analyzed together to enable cross-cultural analysis. To conduct these cross-cultural analyses, this chapter proposes a new kind of quantitative questionnaire-based instrument that includes a section to measure the cultural characteristics of the individual and their level of literacy. This instrument proposal is the main result, since the research field of visual literacy lacks this kind of quantitative approach.
Reconstructing Reading for Students of Color
Authors: White Porchanee A.
Published: October 2021

African American students face discrimination and inequalities in classroom settings on a daily basis. We often think of discrimination and inequality as something being done or said to someone in an inappropriate manner. However, classroom learning material and products should be considered as well. Curriculum, textbooks, and supplemental materials usually do not include information about black history, authors, or poetry. When they are included, they are often used as supplemental material that is not studied, examined, or discussed. In addition, the books they read in class or for pleasure do not necessarily have role models that resemble African American students.
Ethical Dilemmas and Big Data
Authors: Hylving Lena , Lindberg Susanne
Published: October 2021

Using big data in organizations has the potential to improve innovation, accuracy, and efficiency. Big data is also connected with risks for both the organization and society at large. It is therefore vital to improve our understanding of the potential consequences of implementing and using big data. The researchers studied the Swedish Transport Administration to understand their attitude towards implementing big data to predict, for example, the need for road maintenance. The analysis identified four moral dilemmas that the organization deals with in connection to big data. The researchers discuss these dilemmas from the perspective of practical wisdom. Practical wisdom is manifested in context-dependent actions connected to open-mindedness, reflection and judgment. It can be summed up as “the reasonable thing to do” in a unique situation where “not-knowing” is a helpful resource when making wise decisions. This paper seeks to shed light on the importance of practical wisdom when implementing big data.

Authors: Gan Isabel , Sun Rui
Published: October 2021

Information and communication technologies (ICT) have played a pivotal role in facilitating knowledge acquisition and enabling distance education. Yet, knowledge about digital divide in distance education remains limited. This study examines digital barriers that underserved students face in distance education and their coping behaviors during the coronavirus pandemic (COVID-19). Informed by distance education and digital divide literature, this study uses qualitative research method to analyze survey data collected from 206 college students in a four-year public university in the United States. Results revealed five major digital barriers and showed that the distribution of these digital barriers varied by student demographic background and socioeconomic status. Further analysis of respondents’ narratives revealed three coping behaviors, including improvising, building technical assets, and building social assets. Practical implications are provided to educators and policymakers to invest in ICT and implement equity-minded teaching practices to enhance digital inclusion.

Authors: Ghosh Vinit , Kabra Gaurav , Mukerjee Hory Sankar
Published: October 2021

The present study investigates how knowledge leadership affects project performance and quality practices in Information Technology (IT) projects. A questionnaire-based survey was designed to collect responses from 198 mid-level employees of five big Indian IT firms. The data was analysed using PLS-based SEM technique. Our findings revealed that knowledge leadership skills, cooperation and trust, and knowledge integration positively influence project performance and project quality practices. The risk-mitigation efforts of a knowledge leader moderate the relationship between knowledge leadership, project performance and quality practices. The current research has contributed to limited leadership and project management literature available. Knowledge-oriented leadership is a mixture of transformational and transactional leadership and has significant implications on the innovation performance of technology-intensive organizations.
The RFM Model Analysis for VIP Customer
Authors: Chou Tung-Hsiang , Chang Shu-Chen
Published: October 2021

Numerous firms accumulate large quantities of data or transactions after importing information systems and services, which leads to troubles with data procedure. Firms also have demands to find customers’ information from large datasets and to understand how to develop marketing strategies accurately to adjust their operational methods. Therefore, this study proposed customer ranking combined Big Data process based on the RFM model (Recency, Frequency, Monetary) to develop a recommendation algorithm using an association rule, which finds greater recommendation to promote operational effects of firms. We adjust the weight of potential information to perform the customer ranking, which is conducted by using agglomerate hierarchical clustering. Finally, we present the recommendation by the association rule for each customer level.The datasets in this study use actual sales data; therefore, they are authentic and have been practically applied. The metrics of evaluation showed that the recommended system his study proposes is highly accurate.
Integrating Divergent Epistemologies of the Two Influential Views on Organizational Knowledge Creation
Authors: Akbar Hammad
Published: October 2021

This paper integrates the divergent epistemologies of the organizational learning view and the knowledge-creation view on how new knowledge is created in organizations. The former view adopts an information-processing perspective and emphasizes the importance of deep knowledge and higher-level learning, whereas the latter view adopts a social constructionist perspective and stresses the importance of tacit knowledge and interactive dialogue. The paper’s integration uses the theorization of knowledge levels; specifically, the shifts and movements in knowledge trajectories and the inverse relationship between the degree of tacitness and explicitness. The paper contributes greater coherence in our understanding of knowledge creation as well as generates new meaning/insights. The paper concludes by highlighting potential interpretations/insights and implications, before presenting limitations and future research directions.
Multiagent Intelligent Tutoring System for Financial Literacy
Authors: Marin Rafael , Notargiacomo Pollyana
Published: October 2021

Financial literacy is a theme that integrates public policies for the social development of a country and an element to be worked on from different aspects to improve people’s living standards, providing well-being. In this context, Stima is proposed, a system capable of acquiring knowledge from experts and tutors to help students to follow the bases of financial planning and decision-making. It aims to relate different approaches to artificial intelligence and institute a language that, through syntactic, lexical, and semantic analyzes, executed by different agents within the model, makes it possible to define financial profiles and recommend financial planning. The knowledge stored is used to propose financial monitoring standards and provides tools to assist financial decision-making. A set of eight profiles, with three indicators each, was configured by experts inside a prototype, and a volunteer student was accompanied for four months giving validations to the system.
Preoperative Psychosocial Factors and Short-term Pain and Functional Recovery After Hip Arthroscopy for Femoroacetabular Impingement Syndrome
Authors: Jochimsen Kate N. , Noehren Brian , Mattacola Carl G. , Di Stasi Stephanie , Duncan Stephen T. , Jacobs Cale
Published: October 2021

Context

Low mental health scores, depression, and anxiety are associated with worse pain and functional outcomes after hip arthroscopy for patients with femoroacetabular impingement syndrome (FAIS). Preoperative screening of psychosocial factors such as self-efficacy, kinesiophobia, and pain catastrophizing may further aid in identifying patients at risk for poorer outcomes.

Objective

To compare preoperative function and psychosocial factors between patients with and those without elevated postoperative pain 3 months after hip arthroscopy for FAIS.

Design

Prospective cohort study.

Setting

University health center.

Patients or Other Participants

Fifty-one individuals with FAIS (41 women, 10 men; age = 37.6 ± 12.3 years, body mass index = 27.1 ± 4.1 kg/m2).

Main Outcome Measure(s)

Preoperatively, participants completed the Pain Self-Efficacy Questionnaire (PSEQ), Tampa Scale for Kinesiophobia (TSK), Pain Catastrophizing Scale (PCS), 12-Item International Hip Outcome Tool (iHOT-12), and a 10-point visual analog scale (VAS) for hip pain at rest and during activity. Three months postoperatively, they completed the PSEQ, TSK, PCS, iHOT-12, and VAS. Preoperative scores were compared between those with (VAS ≥ 3) and those without (VAS < 3) elevated postoperative pain using Mann-Whitney U tests, and odds ratios were calculated to determine the odds of having elevated postoperative pain and lower postoperative function.

Results

Participants with elevated postoperative pain at rest and during activity had worse preoperative psychosocial health (P ≤ .04). Those with elevated postoperative pain at rest had worse preoperative function (P < .001). The odds of having elevated postoperative pain at rest were 45 times and 4.5 times higher for those with low self-efficacy and high pain catastrophizing, respectively (P values ≤ .03). The odds of having elevated postoperative pain during activity were 7.1, 6.2, and 3.5 times higher for those with low self-efficacy, high kinesiophobia, and high pain catastrophizing, respectively (P values ≤ .04). The odds of having lower postoperative iHOT-12 scores were 7.5 and 14.0 times higher for those with high kinesiophobia and pain catastrophizing, respectively (P values ≤ .03).

Conclusions

Poor preoperative psychosocial health increased the odds of elevated pain and worse function 3 months after hip arthroscopy for FAIS. This is a first step in identifying the psychosocial factors that may contribute to poorer long-term hip arthroscopy outcomes.

The aim of the series of papers on controversies of biliopancreatic drainage procedures is to discuss pros and cons of the varying clinical practices and techniques in ERCP and EUS for drainage of biliary and pancreatic ducts. While the first part focuses on indications, clinical and imaging prerequisites prior to ERCP, sedation options, post-ERCP pancreatitis prophylaxis, and other related technical topics, the second part discusses specific procedural ERCP techniques including precut techniques and their timing as well as management algorithms. In addition, reviews on controversies in EUS-guided bile duct and pancreatic drainage procedures are under preparation.

Effective use of noninvasive ventilation in patients with chronic obstructive pulmonary disease is well-known. However, noninvasive ventilation in patients presenting with altered sensorium and severe acidosis (pH <7.1) has been rarely described. Invasive mechanical ventilation is associated with high mortality in coronavirus disease 2019 (COVID-19), and use of noninvasive ventilation over invasive ventilation is an area of investigation. We report a case of COVID-19-induced acute exacerbation of chronic obstructive pulmonary disease in a 66-year-old male. His past medical history included obstructive sleep apnea, hypertension, cor-pulmonale, atrial fibrillation, and amiodarone-induced hypothyroidism. On presentation, he had acute hypercapnic respiratory failure, severe acidosis (partial pressure of carbon dioxide [PCO2], 147 mm Hg; pH, 7.06), and altered mentation. The patient was successfully managed with noninvasive ventilation, avoiding endotracheal intubation, invasive ventilation, and related complications. Although precarious, a trial of noninvasive ventilation can be considered in COVID-19-induced acute exacerbation of chronic obstructive pulmonary disease with hypercapnic respiratory failure, severe acidosis, and altered mentation.

The Tower of Babel or Ivory Tower? The Reception of Western Translation Research in Russian-language Translation Studies – a Reconnaissance
The aim of this paper is to survey what texts and authors representing Western translation studies have been translated into Russian over the last seven decades and to describe the dynamics of the emergence of these translations as well as possible agendas behind the choices. It also traces, on a partial corpus, to what extent Russian translation scholars tend to cite and quote Western ones. The findings lead to a tentative conclusion that so far TS knowledge has been transferred mainly by unfrequent references to original publications and by way of mediated accounts (reviews, textbook summaries), while translations of particular studies have only recently begun appearing on a wider scale, their impact as yet uncertain.
Od tłumacza do poety i z powrotem. Twórczość przekładowa Adama Ważyka jako część literatury polskiej
Authors: Koronkiewicz Marta
Published: October 2021

From Translator to Poet and Back: Adam Ważyk’s Translation Output as Part of Polish Literature The article offers an analysis of Adam Ważyk’s translation work, particularly in the context of its influence on the shaping of contemporary Polish poetry. The author aims to showcase the impact of Ważyk’s translations on some of the recent developments within Polish literature; to this end, she employs the distinction between translatoras-envoy and translator-as-lawmaker, as proposed by Jerzy Jarniewicz. Ważyk is here seen as an example of a “lawmaker”, and compared to Piotr Sommer – another author influential within a similar audience. The author argues that in his original choice of what to translate, Ważyk was driven by a desire to project onto the Polish context – to reproduce in his native language – a set of poetic and social circumstances associated with the French avant-garde movement; finally it served the goal of making Ważyk’s own work more comprehensible to his Polish readers. At the turn of the 21st century a group of Polish poets who had expressed interest in Ważyk were also attracted to the work of poets translated by Ważyk; the influence of these foreign authors was thus mediated by Ważyk’s own work.
Niestabilny tekst Pana Tadeusza

The Unstable Text of Pan Tadeusz

The article discusses the changes introduced by the successive editors of Adam Mickiewicz’s narrative poem to the text version published by the poet himself. The most important one is undoubtedly the addition of the poem considered the “epilogue” to Pan Tadeusz, allegedly lost by Mickiewicz. No less radical are the interventions consisting in supplementing the text with fragments from the autograph or with the poet’s later additions made to the already printed text, as well as in corrective conjectures in instances regarded by the publisher as slips of the pen. The article compares the surviving authorial versions of the text, demonstrating that Mickiewicz himself treated his work as a continual process and tested new solutions on various occasions; however, there is no evidence that he intended to introduce them into the printed text.
Breve revisão sobre a escolha de imunobiológicos na presença de comorbidades: contraindicações relativas e absolutas
Authors: Assad Rodrigo Lupino
Published: October 2021

Nas últimas duas décadas, o uso de imunobiológicos em tecidos alvos específicos acarretou a melhora dos desfechos de diversas doenças autoimunes sistêmicas. Entretanto, seus efeitos em outros órgãos ou sistemas, relacionados com as comorbidades, passaram a ser relevantes.
De modo geral, os principais estudos disponíveis e relacionados com as comorbidades são com artrite reumatoide, espondilite anquilosante e artrite psoriásica. No entanto, essas informações não permitem extrapolar as evidências a todas as doenças reumáticas, mas sim obter dados com o intuito de colaborar na tomada de decisão.
A Tabela 1 ilustra algumas das comorbidades encontradas em pacientes com doenças autoimunes sistêmicas. No presente artigo serão abordadas as primeiras quatro condições.
Manejo pré-operatório dos agentes imunobiológicos em pacientes reumatológicos
Authors: Pontes Filho Marco Antonio Gonçalves
Published: October 2021

Pacientes com doenças reumáticas sistêmicas geralmente estão em uso de uma ou mais medicações, com intuito de alterar a função do sistema imunológico ou suprimir o processo inflamatório e, assim, controlar a atividade da doença subjacente. Com o surgimento dos agentes imunobiológicos nos últimos anos, houve uma ampliação do arsenal terapêutico no manuseio desses pacientes, para garantir uma melhor eficácia no controle da doença e retardo na progressão radiológica. Entretanto, eles também aumentam o grau da imunossupressão e a chance de complicações infecciosas.
Apesar desse avanço na terapêutica, alguns pacientes com doença mais avançada e grave, refratários e/ou que não receberam um tratamento adequado no início da doença acabam necessitando de tratamento cirúrgico por conta do dano estrutural acumulado. A intenção desse tipo de abordagem é de restaurar a mobilidade articular e melhorar a qualidade de vida. Tais procedimentos incluem artroscopias, sinovectomias, artrodeses, reparos tendíneos e próteses articulares.
Os agentes biológicos agem inibindo citocinas inflamatórias (como TNF alfa, IL-1, IL-6), bloqueando a coestimulação celular ou reduzindo a produção de anticorpos (imunoglobulinas), tendo como resultado final a redução do processo inflamatório causado pela doença reumatológica (Tabela 1). É importante, porém, ressaltar que a inflamação é um processo fundamental para que ocorra a cicatrização normal da ferida operatória, e também a resposta do sistema imunológico para proteção contra infecções por patógenos no sítio cirúrgico1 (Tabela 2) (Figura 1).
Apesar das inúmeras evidências do benefício do tratamento com agentes biológicos, é descrito que esta classe de medicações tende a aumentar o risco infeccioso em geral. Existem relatos descrevendo aumento nas taxas de infecção pós-operatória e retardo na cicatrização da ferida operatória nos pacientes em uso dessas medicações. Além disso, sabe-se que a própria artrite reumatoide (AR) é um fator de risco para infecção pós-operatória em artroplastias, quando comparada aos pacientes com osteoartrite, com risco estimado 2,6 vezes maior. Esses dados fazem com que seja necessária uma atenção especial aos pacientes durante o uso dos agentes biológicos, incluindo também os períodos pré e pós-cirúrgicos.
O manejo desses pacientes no período perioperatório, considerado um cenário especial, torna-se um desafio para o reumatologista. Por um lado, existe o risco infeccioso já descrito. Por outro lado, a suspensão das medicações imunossupressora pode levar a flare da doença reumática, influenciando na recuperação desses pacientes no pós-operatório, até mesmo pela dificuldade de conseguir uma reabilitação adequada.

OBJETIVO: identificar las competencias que han desarrollado durante su proceso de formación en aulas virtuales los estudiantes del Pedagógico Gervasio Rubio. MÉTODO: investigación cuantitativa de tipo descriptivo correlacional, la muestra se conformó con 72 estudiantes, seleccionados aleatoriamente, a los cuales se les aplicó el cuestionario competencias para el aprendizaje en contextos virtuales, de modelo Likert que consta de 21 ítems, con cinco opciones de respuestas y tiene un índice de confiabilidad de 94. RESULTADOS: los resultados evidenciaron que el 50% de los estudiantes afirman haber desarrollado la competencia de búsqueda y selección de información, y solo el 8.3% de alcanzar competencias afectivas relacionadas con la empatía. CONCLUSIÓN: en vista de ello la institución debe desarrollar esta competencia a partir de la creación de estrategias que permitan establecer relaciones de los estudiantes, entre ellos y con los profesores. A partir del análisis se evidencia que la e-learning contribuye en la generación de la autonomía, uno de los objetivos más relevantes de la educación.
