There are many factors that affect appearance and spreading of the red heart in beech stands. Therefore, this research presents an analysis of site quality class and taxation elements (diameter at the breast height, height of the tree and age of the tree) influence on the participation and distribution of the red heart in the forest compartments 107. M.U. „Gosteljaˮ - (II- quality class) and 47. M.U. „Srednja Drinjačaˮ - (III- quality class). The appearance of the red heart on the beech trees considering on the site quality class was researched, as well as the red heart appearance frequency in dependence on the tree diameter at the breast height and age of the tree, size and distribution of the red heart in the longitudinal and transverse direction. The results of research showed that the number of trees with the red heart and the length of the technical roundwood with the red heart increase with increase of diameter at the breast height (age of the tree). As well, it was established that the appearance frequency of the trees with red heart considering the diameter at the breast height (the age of the tree) was larger on the stands belonging low quality site classes. The site quality class affects the distribution of the red heart at the thicker beech trees in the longitudinal direction, while at the thinner and trees of medium diameter, the influence of site quality class on the distribution of the red heart is not expressed in great extent. Larger diameters of the red heart in average have beech trees on the low quality site classes.

Published: January 2022

Este artículo explora las brechas de género en la gobernanza universitaria, analizando evidencia sobre la distribución de puestos por sexo, tanto en la alta dirección y dirección académica en las universidades peruanas, como en las planas docentes. Se evidencia que hay poca participación de las mujeres en los órganos de gobierno universitario, información que es analizada según el tipo de universidad y el campo de conocimiento de la facultad académica. Asimismo, se hace una reconstrucción del escalafón docente, evidenciando que existe una limitada presencia de mujeres en puestos de docentes principales con una dedicación a tiempo completo en la universidad; lo que impediría una eventual elección como representantes al rectorado. Siendo las mujeres un grupo cuantitativamente minoritario en los puestos de las universidades peruanas, el estudio busca brindar evidencia que sirva para el impulso de políticas de la igualdad de género. En particular, aquellas que fomenten una mayor presencia de mujeres en la carrera docente en puestos de alta consideración y que faciliten a las nuevas generaciones de estudiantes mujeres, el contar con referentes de liderazgo, gestión y mentoría académica dentro de las universidades.

Comparing Environmental Financial Guarantee Schemes in Kenya and South Africa
Authors: Omedo Geoffrey , Muigua Kariuki , Mulwa Richard , Kibugi Robert
Published: January 2022

Kenya and South Africa have enacted some laws that inculcate economic incentives schemes as key elements of their environmental regulatory terrain. While Kenya has advanced the use of Environmental Performance Deposits (EPDBs), South Africa has adopted the use of the Financial Provisioning Regulations, applied specifically for the upstream mining sector. This article reviews the use of financial assurance schemes in environmental management and their specific application to the upstream mining sectors in the two countries. The data used in the analysis is from literature review, key informant interviews, interview schedules, and focus group discussions. Results indicate that while the use of financial provisioning is a well-established practice in South Africa, in Kenya only one company has deposited funds to the environmental regulator as a security for good environmental practices. A comparative analysis of the regulatory framing for financial assurance instruments in Kenya and South Africa demonstrates some similarities in terms of requirement for public participation, requirement for periodic review of the bonds, use of the bonds for environmental rehabilitation; and some differences such as requirement for use of cash and/or financial instruments, how to treat the accrued interest from the deposited funds, and how the deposit bond amounts are set. Largely, both countries acknowledge the importance of economic incentives in their environmental management frameworks. The article recommends strengthened regional cooperation to enhance the application of financial assurance in the law for effective environmental management in Africa.
Quality of Life in the Swedish General Population During COVID-19 - Based on pre- and post-pandemic outbreak measurement
Authors: Persson Ulf , Olofsson Sara , Gu Ning Yan , Gong Cynthia L. , Jiao Xiayu , Hay Joel W.
Published: January 2022

The outbreak of the pandemic COVID-19 (Coronavirus) has resulted in various international and national strategies, including non-pharmaceutical interventions (NPIs) such as social distancing and travel bans, which have purportedly mitigated the health loss due to the pandemic but also given rise to a severe economic crisis. Both factors, the pandemic and the NPIs, can be expected to have an impact on the Health-Related Quality-of-Life (HRQoL) of the population. The objective of this study was to estimate the impact on HRQoL of the Swedish adult population during the outbreak of the COVID-19 pandemic. A web-based survey was sent to randomised samples of the adult Swedish population before the outbreak of the pandemic in Sweden in February 2020 (n=1,016) and during the outbreak of the pandemic. The first wave pandemic data was collected in April 2020 (n=1,003), one-month after the outbreak and, the second wave data was collected in January 2021 (n=1,013), after 10-months living under the pandemic. HRQoL was measured using the EQ-5D-5L in the pandemic surveys, whereas the Visual Analogue Scale (VAS) was used in all surveys. The results suggested a reduction in average HRQoL as measured by VAS in the adult Swedish population, with 0.059 points reduction in VAS in April 2020 and 0.074 points reduction in January 2021, compared to the pre-pandemic measurement in February 2020.  The loss in HRQoL was significant among respondents in the working age population (<65 years), suggesting that the social and economic impact of NPIs were the primary drivers for this specific cohort. Findings of this study supports a wide public health perspective and future HRQoL measurements at the population level throughout the pandemic.

Authors: Cavalcante Reidner , Soares Alcimar , Lamounier Edgard
Published: January 2022

In this thesis, we propose a system that uses immersive Virtual Reality (iVR) and EMG signal processing (muscle activity) to provide a training environment for amputees who are supposed to use a myoelectric prosthesis. We also investigate the efficiency of learning how to control a virtual prosthesis with and without sensory feedback. Our results show that virtual training can be greatly improved when proper tactile feedback is provided, especially for myoelectric controlled prostheses.

Authors: Fernandes Larissa , Damasceno Eduardo Filgueiras
Published: January 2022

There were several ways to teaching microbiology, but when it is hands-on into laboratory practice, biosafety must take priority. To mitigate this limitation, some approaches use virtual reality technology to simulate the environment. However, all are shows as multimedia-based, didactic simulators and function as an extension of the textbook. This short paper addresses a proposal to develop a virtual reality environment for teaching microbiology that can be used as a tool to explore the microbiological environment for the study of viruses and bacteria harmful to humans. Finally, this work aims to develop a prototype tool to facilitate the teaching of microbiology, contemplating both the pedagogical requirements of the educational software and the technical requirements needed to build an immersive virtual reality environment. Added to this proposal is the requirement to present a low-cost tool for both editing and visualization.

A Low-Complexity Deep Neural Network for Signal-to-Interference-Plus-Noise Ratio Estimation
Authors: Kagami Roberto M. M. , Mendes Luciano L.
Published: January 2022

Mobile network technology has been driven by a huge demand for throughput and reliability to support new emerging services. The quality of service is based on measurements of indicators with a high level of precision. Accurate controlling of parameters to fulfil the quality requirements will be essential for future applications. In LTE and 5G standards, the Channel Quality Indicator can be calculated using different algorithms. It is key to determine the best coding and modulation as well as the power control. Thus, it depends on the exact signal-to-noise ratio estimation. MSE based on hard-decision has a very low computational cost, however, it can insert non-linearities. This paper proposes a neural network to estimate an SINR from a modified MSE function.
Towards 6G Network Slicing
Authors: Moreira Rodrigo , Silva Flávio de Oliveira
Published: January 2022

Networks should connect communicating peers, supporting vertical services requirements. The network evolution towards 6G requires native network slicing techniques. Some literature approaches claim network slice realization, but they do not convincingly address the deployment across multiple Autonomous Systems. This work investigates the current 6G network slicing landscape, presents some gaps, and introduces the concept of the recursive network slicing between multiple Autonomous Systems, supported by the NASOR approach. This innovative concept supports implementing new network services required by the 6G vision. This work also sheds light on the 6G requirements for network slicing.

The Modern Universal Total Knee Arthroplasty: Maximized Value, Streamlined Efficiency
Authors: Bonner Bryant , I. Law Jesua , Hofmann Erin , Dacus Eric
Published: January 2022

A universal total knee arthroplasty system able to accurately resurface either left or right knees of all shapes and sizes is compelling as there is an increased need for improved efficiency and value. With a modern universal total knee system, a single instrument tray can be utilized for more than 90% of cases and doesn’t require any specific customization or disposable instruments. This streamlined workflow is accomplished with unique instrumentation that features a symmetrical femoral and tibial implant for all patients. Symmetrical tibial implants have been shown to have equivalent outcomes and low complications compared to asymmetric tibial trays. The universal symmetrical femoral implant, with its deepened trochlear groove, allows for optimal patellar tracking and recent studies have demonstrated this symmetrical femoral implant to have comparable femoral rollback and axial rotation to native knees. This efficient instrumentation reduces overall inventory, decreases turnover times, and exposes fewer instruments that may otherwise be susceptible to contamination. All without detriment to the patient outcome or surgeon workflow. Studies have shown clinical scores of the modern universal total knee arthroplasty system are a great value not only to the surgeon but also to the healthcare system as a whole—a necessity in modern healthcare.
New Approaches for Improved Service Delivery in Rural Settings
Authors: Oluwafemi Dipeolu Isaac
Published: January 2022

The health status of the people in rural areas is faced with challenges primarily due to availability, acceptability, financial accessibility to healthcare services. These include traditional and cultural beliefs, behavioural norms that explain community viewpoints of social roles and various community members’ functions. Rural and remote areas are medically underserved, access to healthcare services is difficult sometimes. Distance covered to access the nearest available health facility by some rural dwellers is discouraging. Thus, moving critically ill or injured persons is hampered because of long-distance or poor transportation means. In the end, many prefer to use traditional medicine than travel that long distance for medical treatment. Recently, healthcare delivery systems have focused on innovative approaches to improve health outcomes, control costs, and foster achieving the Sustainable Development Goals (SDGs). One of these innovations is mHealth (Short Messaging Service) [SMS] texts, which have peculiar attributes, making it particularly suitable for health care in rural and hard-to-reach areas in Low and Middle-Income Countries (LMICs). Moreover, text-messaging interventions are uniquely suited for underserved populations. This chapter highlights some interventions on the uses and benefits of SMS text applications in healthcare service delivery.

Authors: Wang Ping , Shi Tongtong , He Rui , Yuan Wubei
Published: January 2022

Prompt and accurate prediction of traffic flow is quite useful. It will help traffic administrator to analyze the road occupancy status and formulate dynamic and flexible traffic control in advance to improve the road capacity. It can also provide more precise navigation guidance for the road users in future. However, it is hard to predict spatiotemporal traffic flow data in large scale promptly with high accuracy caused by complex interrelation and nonlinear dynamic nature. With development of deep learning and other technologies, many prediction networks could predict traffic flow with accumulated historical data in time series. In consideration of the regional characteristics of traffic flow, the emerging Graph Convolutional Network (GCN) model is systematically introduced with representative applications. Those successful applications provide a possible way to contribute fast and proper traffic control strategies that could relieve traffic pressure, reduce potential conflict, fasten emergency response, etc.
Hierarchical Sliding Mode Control for a 2D Ballbot That Is a Class of Second-Order Underactuated System
Authors: Ba Pham Dinh , Lee Soon-Geul , Hang Bui Thi , Phat Truong Tien
Published: January 2022

2D Ballbot is an actual under-actuated system with second-order nonholonomic velocity constraints and input coupling case where only control input is employed to control two outputs of the system. Controlling such a system is not easy because it faces many changelings including nonlinearities, external disturbances, and uncertainties. This study proposed a robust control system for a Ballbot mobile robot. The proposed control scheme is constructed using the hierarchical sliding mode control technique. The kinematics and dynamics of the Ballbot are derived. A Lyapunov function is used to prove the stability of the closed-loop control system. The stabilizing and transferring problems are investigated through several simulations and experiments by using the actual Ballbot platform.

Konstrukcija i provera skale socijalne uključenosti i isključenosti studenata
Authors: Mikanović Brane , Popović Kristijan
Published: January 2022

Cilj rada je da se konstruiše skala za merenje socijalne kompetentnosti studenata, koja ima prihvatljivu (visoku) pouzdanost. Uzorak istraživanja čini 222 studenta, starosti između 19 i 28 godina (M=22,41; SD=1,66). Uz ajteme je ponuđena petostepena skala kojom ispitanici procenjuju stepen saglasnosti sa sadržajem usmerenim na socijalnu uključenost i/ili socijalnu isključenost. Konačnu verziju instrumenta određuju dve zasebne skale, socijalna uključenost sa 12 i socijalna isključenost sa 14 ajtema. Dobijeni koeficijenti pouzdanosti za obe skale su zadovoljavajući, a=0,83 za skalu socijalne uključenosti i a=0,86 za skalu socijalne isključenosti. U proveri diskriminativnosti utvrđeno je da postoji pomeranje skorova prema višim vrednostima na skali socijalne uključenosti (S=-0,97, Ku=1,12) dok distribucija skorova na skali socijalne isključenosti, prema istim parametrima, ne odstupa značajno od normalne (S=0,52, Ku=0,25). Kolmogorov-Smirnov test (K-S=1,50, p<.05) potvrđuje statistički značajno odstupanje skorova od normalne distribucije na skali socijalne uključenosti. Obe skale su predstavljene glavnim komponentama koje varijansu objašnjavaju sa 37,57% zasićenosti, dok sa sumativnim skorovima ostvaruju korelaciju r=0,99. Preliminarni rezultati ukazuju da su predstavljene karakteristike skale zadovoljavajuće. Naredni koraci u potpunoj validaciji skale i njenog korištenja kao konstruisanog istraživačkog instrumenta, sa utvrđenim mernim karakteristikama, podrazumevaju proveru skale na drugim uzorcima i ispitivanje odnosa sa relevantnim spoljnim kriterijskim varijablama.
Contemporary concepts of exceptional giftedness and its development: A way to harmonize social perceptions, and enhance institutional treatment and self-perception
Authors: Kostadinovska-Stojčevska Bisera , Kevereski Ljupčo
Published: January 2022

If we view the civilizational development through the prism of the socio-historical continuum, it seems that we must agree with the claim that the gifted and talented are the creators of the general development of civilizations. This trend continues today, when it is claimed that in the next 20 years, the talented and gifted will inevitably be the most important asset in every institution, especially in contemporary companies. Most of these individuals are believed to perform cognitive tasks at higher mental levels, in which metacognitive thinking that is dominant. This thinking forms a special mental structure, recognizable in such individuals. This paper operates under the assumption that, there is no clearcut picture of the psychological profile of the exceptionally talented with their awe-inspiring performances of their extraordinary abilities which impress the world. Their impressive and fascinating achievements in one or more areas of human life motivate them to be more involved in the world of today. Hence, papers that deal with both theoretical and empirical findings often face a variety of dilemmas and problems regarding the demystification of the psychological code of the exceptionally talented in various scientific and artistic fields. The focus of this paper are the talented and the factors which determine their "superhuman achievements". This paper strives to identify the psycho-physical features of the exceptionally talented and their noteworthy performance in various fields - performance that is often referred to as exceptional or expert-like. The aim is to identify the different traits that exceptionally talented individuals working in different fields and arts (science, sports, music, etc.) have. The paper uses the meta-analysis of documentation method, which enables an objective insight into the most significant performances of the exceptionally talented. The results obtained through this method show that the exceptionally talented show a clear, distinctive psychological pattern or. The results obtained reflect a recognizable psychological cod which is unique and specific to those at the pedestal of great achievements. The results will be especially useful for the harmonization of the social view of talent and for the institutional treatment of the talented individuals. Finally, it will improve the talented individuals' self-perception which will positively impact their self-perception which is of great importance for their further educational, psychological and social perception.
Qualitative and quantitative phytochemical evaluation of Quassia undulata (Guill. & Perr.) D. Dietr. leaves using different solvent polarities
Authors: Oduola Lawal , Olufunso Adeniyi , Oluwole Ariwoola
Published: January 2022

This study investigated solvent effects on the phytochemical composition of Quassia undulata leaves a medicinal plant used in treating arrays of diseases including fever and cough. The leaves were collected, washed, air-dried, pulverized and evaluated for some inherent phytochemicals using four different solvent systems based on their polarities. The solvents are methanol, acetone, ethyl acetate and chloroform. The methanol extract was found to have the highest number of secondary metabolites (saponins, tannins, flavonoids, steroids, coumarins, anthraquinones, alkaloids and phenols). None of the extracts tested positive for the presence of phlobatannins, terpenoids and emodins. The methanol extract was further analyzed quantitatively for some of the determined phytochemicals. Tannins had a concentration of 3.131 mg of catechin equivalents per 100 mg sample (mg CE/100g), alkaloids-5.200 %, total phenolics-11.828 mg of gallic acid equivalents per gram of extract (mg GAE/g), flavonoids-8.074 mg of quercetin equivalents per gram of extract (mg QE/g) while 0.673 % saponins were detected. The presence of these secondary metabolites might justify the ethnomedicinal uses of Quassia undulata leaves as their bioactivity has been found to be dependent on the solvent used for extraction.

Authors: Jelić Sreten , Kolarević Vukašin
Published: January 2022

Depopulation of rural areas as a global process has not bypassed our country either. Demographic changes in the structure of the population have especially affected the rural population and the village in our society. Depopulation of a number of villages, especially in South-eastern Serbia, means that some villages are almost empty or with older people and a minor share of young people. The aim of this paper is to analyze the availability of services, social participation contents and the quality of infrastructure in rural settlements. Therefore, the research was conducted on the basis of a survey questionnaire in 176 rural settlements in the municipalities of Bojnik, Crna Trava, Medveđa, Surdulica and Trgovište. The findings indicate the extent to which negative indicators of the number of inhabitants in rural settlements are related to available services, social participation contents and infrastructure based on the correlation analysis.

What makes millennials blow the whistle?: From cultural to socio-psychological perspectives on whistleblowers
Authors: Nikolić Nemanja , Bojić Ljubiša , Jevtović Ana
Published: January 2022

Whistleblowing cases that shook intelligence community in the last decade have something in common. Edward Snowden, Bradley Manning, and Reality Winner are all members of a single generation - Millennials. We challenge the viewpoint that depicts this generation as a potential "insider threat." Millennials do have certain psychological traits and attitudes that can be related to tendencies towards whistleblowing, but these findings still do not approve the rhetoric that creates distrust towards the generation. This paper proposes a shift from the cultural to the socio-psychological level of analysis, with respect to both cultural and individual characteristics of whistleblowers, but puts more emphasis on the social dimension. In comprehending recent cases of leaking classified information, it is not enough to reduce explanation to some individual personality traits or hide behind an abstraction, such as the concept of generation. To shed more light on the issue, we introduce the concept of the imagined community, such as the open source community, promoting free Internet and transparency of information and knowledge. Therefore, mental membership in an imagined community might be more decisive for blowing the whistle than the global set of values related to the whole generation of Millennials.
Creencias y actitudes del estudiantado de trabajo social en torno a la violencia de género: una investigación en la universidad de Huelva
Authors: Expósito Cívico Inmaculada , Piedra Cristóbal Julio , Martos Sánchez Cinta
Published: January 2022

La violencia de género es un problema sociopolítico actual que exige atención prioritaria por parte de los poderes públicos. Este artículo muestra los resultados obtenidos en la investigación sobre creencias y actitudes sexistas realizada sobre una muestra de 141 estudiantes de primer y cuarto curso Trabajo Social de la Universidad de Huelva. Se aplicó el “Inventario de Pensamiento Distorsionado sobre la Mujer y la Violencia (Echeburúa y Fernández-Montalvo 1997) y el “Inventario de Deseabilidad Social” (Crowne y Marlowe 1960). También se preguntó sobre la formación recibida respecto a la violencia de género. Los resultados muestran la pervivencia de estereotipos sexistas entre el estudiantado, lo cual dificulta la identificación de la violencia. Se concluye la necesidad de incluir en los planes de estudio materias específicas en violencia de género, pues la formación de quienes son el futuro profesional es esencial para desterrar actitudes indeseadas a la hora de abordar una intervención adecuada en esta materia.

L’anàlisi de la  reutilització metgiana d’algunes fonts permet examinar els recursos formals de la seva escriptura, així com aprofundir en les relacions de Metge amb els textos clàssics i italians. Lo somni evidencia una nova perspectiva literària i una clara actitud filògina en l’estela de les relectures que els grans mestres del Trecento, Petrarca i Boccaccio, havien realitzat de clàssics llatins com Valeri Màxim.  Paraules clau: Bernat Metge, Lo somni, Petrarca, Boccaccio, Valeri Màxim.Abstract: This paper explores some references in books III and IV of Lo somni on the question about «l’amor de fembres» and the pernicious effects of immoderated lust, from the perspective of the Latin sources used in the Catalan text. The analysis of Metge’s reuse of some sources allows to examine the formal resources of his writing, as well as to delve into the connections of Bernat Metge with classical and Italian texts. Lo somni shows a new literary perspective and a clear philogynist attitude imitating the re-readings that the great masters of Trecento, Petrarch and Boccaccio, had made of Latin classics such as Valerius Maximus. Keywords: Bernat Metge, Lo somni, Petrarch, Boccaccio, Valerius Maximus.

Published: January 2022

Resumen: El objetivo de esta contribución es dúplice: en primer lugar, presentar Agenda culinaria para 1896. Libro de la compra. Con minutas y recetas para cada uno de los días del año, un libro que muestra características editoriales que hacen que no sea solo un recetario, sino también un producto de consumo que se enmarca en el auge de las publicaciones relacionadas con la gastronomía a finales del siglo XIX; en segundo lugar, ofrecer un estudio del léxico culinario contenido en esta obra, con el fin de detectar extranjerismos, neologismos y otras creaciones léxicas surgidas a raíz del contacto entre la cocina española e ingredientes y platos procedentes de otros países y culturas. Así pues, se ha analizado la trayectoria lexicográfica de tres términos (kari, uspot, pilaw) que ofrecen una muestra de la circulación europea e internacional del léxico de la comida y la gastronomía, cada uno mediante vías de penetración y acomodación en el caudal léxico español diferentes, como la doble entrada (kari) o el préstamo efímero (uspot); asimismo, se ha podido establecer un caso de retrodatación (pilaw).Palabras clave: galicismos. gastronomía, recetarios, lexicología, lexicografía, préstamo.Abstract: The objective of this paper is two-fold: firstly, it aims at presenting Agenda culinaria para 1896. Libro de la compra. Con minutas y recetas para cada uno de los días del año, a book that displays editorial features that turn it into something more than a recipe book. As a matter of fact, it may be considered a consumer product that fits into the boom in publications related to cookery in the late 19th century. Secondly, it offers a study of the gastronomy lexicon that can be found in this volume, with the purpose of detecting foreign words, neologism and other lexical creations brought about by the contact between Spanish cuisine and ingredients and those from other countries and cultures. Therefore, this paper analyses the lexicographical trajectory of three terms (kari, uspot, pilaw) that offer a sample of the European and international circulation of lexicon of food and cookery, each one showing different paths and strategies of entry in the Spanish lexicon: double entry (kari), momentary loanwords (uspot), and predating (pilaw).Keywords: gastronomy, recipe books, lexicology, lexicography, loanword.

Authors: Ariolfo Rosana
Published: January 2022

Resumen: El presente estudio analiza cuantitativa y cualitativamente el tratamiento de los culturemas gastronómicos de América lematizados en los tres diccionarios bilingües italiano-español más recientes y de gran tamaño, es decir, el Garzanti (2018), el Zanichelli (2020) y el Hoepli (2021). Específicamente, y tras definir terminológicamente los culturemas en el ámbito de la lexicografía bilingüe, este trabajo tiene por objeto, en primer lugar, cuantificar y clasificar por tipología y zona de origen los americanismos pertenecientes al ámbito de la alimentación que se recogen en las obras mencionadas. En segundo lugar, se analizará qué tratamiento metalexicográfico se ha dado a dichos culturemas en los tres diccionarios mencionados, esto es, si ofrecen equivalentes de traducción, o si aportan definiciones culturales o explicaciones enciclopédicas, con el fin de determinar qué tipo de actividades comunicativas podrán ayudar a resolver las soluciones adoptadas.Palabras clave: americanismos, culturemas, léxico gastronómico, lexicografía italoespañola, diccionarios bilingües.Abstract: The present study analyzes quantitatively and qualitatively the treatment of American gastronomic cultural words lemmatized in the three most recent and large Italian-Spanish bilingual dictionaries, i.e. Garzanti (2018), Zanichelli (2020) and Hoepli (2021). Specifically, and after terminologically defining cultural words in the field of bilingual lexicography, this paper aims, first, to quantify and classify by typology and area of origin the Americanisms belonging to the field of food that are collected in the mentioned works. Secondly, we will analyze what metalexicographical treatment has been given to these cultural words in the three mentioned dictionaries, that is, if they offer translation equivalents, or if they provide cultural definitions or encyclopedic explanations, in order to determine what kind of communicative activities the adopted solutions can help to solve.Keywords: Americanisms, cultural words, gastronomic lexicon, Italian-Spanish lexicography, bilingual dictionaries.
La identidad en el plato. El camino identitario argentino a través de sus alimentos
Authors: Magnani Ilaria
Published: January 2022

Resumen: Junto a la fundamental función material que desempeña, es bien conocido el valor simbólico de la alimentación, capaz de albergar significados culturales, afectivos, identitarios –ya sea a nivel personal que nacional–. Enfatizan estos temas y sus implicaciones históricas estudiosos como Montanari y Flandrin entre otros. Basándome en dichas consideraciones, me propongo rastrear la descripción de las tradiciones alimentarias argentinas para delinear su representación en relación con la naciente identidad nacional, observar sus modificaciones y analizar los significados que ellas entrañan. A este fin me basaré en un corpus formado por: José Antonio Wilde, Buenos Aires desde setenta años atrás (1881); Domingo Faustino Sarmiento, Recuerdos de provincia (1850); Lucio Mansillas, Mis memorias (1904) y Una excursión a los indios ranqueles (1870).Palabras clave: gastronomía, literatura argentina siglo XIX, José Antonio Wilde, Domingo Faustino Sarmiento, Lucio Victorio Mansillas.Abstract: Along with the fundamental material function that it performs, the symbolic value of food is well known, capable of harboring cultural, affective, and identity meanings –either at a personal or a national level–. These themes and their historical implications are emphasized by scholars such as Montanari and Flandrin, among others. Based on these considerations, I propose to trace the description of Argentine food traditions to delineate their representation in relation to the nascent national identity, observe their modifications and analyze the meanings that they entail. To this end I will base myself on a corpus made up of: José Antonio Wilde, Buenos Aires desde setenta años atrás (1881); Domingo Faustino Sarmiento, Recuerdos de provincia (1850); Lucio Mansillas, Mis memorias (1904) y Una excursión a los indios ranqueles (1870).Keywords: gastronomy, 19th century Argentine literature, José Antonio Wilde, Domingo Faustino Sarmiento, Lucio Victorio Mansillas.

This article examines the development of digital competencies of the pedagogue and presents the toolset for their assessment and self-assessment. The subject of this research is the process of detecting digital competencies of the pedagogue. An attempt is made to structure the key indicators of the formation of digital competencies of the pedagogue and conduct their level differentiation. The author provides the matrix of the development of digital competencies, which may become a benchmark for the competent control over student’s learning activity in digital educational space. Such matrix serves as the theoretical model for detecting the level of formation of IT-competencies of the pedagogue in the conditions of rural and ungraded schools. The three levels of the development of digital competencies are presented therein. In their professional development, the pedagogue undergoes the three stages, which can designated as “Application – Adaptation – Elaboration”. This indicates the three levels of development IT- competencies of the pedagogue implemented in the following types of professional activity: work with information resources; control over the learning, upbringing and developmental processes; elaboration of electronic educational materials, creation of educational environment, and countering destructive trends on the Internet; self-management of professional development of the pedagogue. The criteria are formulated in accordance with the highlighted types of professional activity of the pedagogue. The level of development IT-competencies is detected through the analysis of pedagogical situations, when the pedagogue must choose one of three behavioral strategies that are associated related with the general use, general pedagogical, and subject-methodical competency respectively. The article is prepared within the framework of the state task of the Ministry of Education No. 073-03-2021-015 / 2 of July 21, 2021 for the implementation of research works (on the topic “Research and development of methodical recommendations on the use of modern digital and Internet technologies on the example of rural and ungraded schools in the context of ensuring quality educational process (the online format of implementation is offered)”.
