La régulation du comportement et des émotions pendant l’adolescence
Authors: Dumontheil Iroise
Published: December 2020

Les recherches en neurosciences cognitives des deux dernières décennies ont démontré qu’au-delà de la petite enfance, le cerveau continue de changer de manière significative pendant l’adolescence. La maturation des circuits neuronaux sous-tendant les émotions, la motivation et le renforcement, la cognition sociale et les fonctions exécutives sont plus ou moins sensibles aux changements hormonaux associés à la puberté et progressent différemment pendant l’adolescence. Les adolescents ressentent les émotions de manière plus forte et sont plus sensibles au contexte social que les adultes. Par conséquent, ils peuvent rencontrer des difficultés de régulation de leurs émotions et actions dans certains contextes. Ces difficultés peuvent devenir chroniques et mener à des troubles de la santé mentale, comme la dépression, l’anxiété et l’addiction. Mais l’adolescence peut aussi être considérée positivement comme une période d’exploration et de flexibilité cognitive, pendant laquelle les individus deviennent indépendants et construisent leur concept de soi. L’éducation peut jouer un rôle dans le développement des adolescents à travers des programmes ayant pour but de renforcer leur capacité de réguler leurs émotions et leur comportement.

A EJA é uma modalidade do Ensino, estabelecida e assegurada por várias leis que amparam todos os que não puderam realizar seus estudos em idades ideais, dando-lhes a oportunidade de iniciar e/ou concluí-los. Destarte, torna-se salutar ampliar o debate acerca da EJA, rediscutir o lugar que a EJA ocupa nos cursos de licenciaturas no País, assumir que a EJA é, antes de tudo, uma questão de construção histórica-social do sujeito. O presente estudo tem como objetivo ampliar a discussão sobre a formação inicial docente para atuação na EJA. Em especial, o espaço que essa ocupa nos cursos de Licenciatura do IFRO, espaço privilegiado para formação docente. Para isso, a pesquisa de cunho qualitativo será baseado nos Projetos Pedagógicos dos Cursos (PPC’s) da Instituição. A pesquisa evidenciou a necessidade de repensar os currículos dos cursos de licenciatura no que se refere à formação para o trabalho com a EJA.
Assessing offshore wind power resources in British Columbia
Authors:   , Bakri Talaat
Published: December 2020

Wind resources are investigated and estimated offshore of the northern and central coasts of British Columbia, Canada. Remote sensing-based wind speed observations from a Synthetic Aperture Radar (SAR) mounted on the Canadian RADARSAT-2 satellite are used for mapping offshore winds. In addition, in-situ wind speed observations extracted from several buoys distributed in the study region are used to analyze the temporal and spatial wind speed variations in relation to wind power generation. Sustained winds above several wind turbine thresholds are analyzed and values of 50-yr and 100-yr return extreme wind speed levels are calculated. The wind variability analysis suggests few interruptions to power generation by either very low wind speeds or extreme wind speed events with high spatial variability between offshore areas and sites located within the coastal mountains. The SAR wind speed fields are characterized by a high spatial resolution but cover a period of less than 2.5 years with a random temporal availability. The SAR fields are extrapolated to reanalysis long-term wind fields that are available over a climatological time period with a sub-daily temporal resolution but a coarse spatial resolution. The extrapolation procedure is developed by applying a statistical downscaling model and a bias-based correction method. Wind fields from both methods are validated against the in-situ observations from buoys. The extrapolated wind fields are used for mapping offshore winds by creating a robust wind climatology that represents the mesoscale wind variance as well as the diurnal wind variability. This wind climatology is used to calculate the wind statistics and power density, in addition to estimate offshore wind resources. Viable areas for wind power development are defined by using high resolution bathymetric data and considering the general environmental and ecological constraints in the region. The estimated offshore wind resource energy using only theiv determined viable areas is found to resemble a large portion of the current total power generation in British Columbia. Most suitable areas for offshore wind farms are determined by developing criteria based on a combination of the turbine tower technology, water depth zoning and power density values.
Generalized Stability Criteria for Special Linear Automatic Control Systems with a Time Delay
Authors:   National Research University «Moscow Power Engineering Institute», NIKOL’SKIY Aleksey A.
Published: December 2020

Matters concerned with stability of special linear automatic control systems with a time delay are considered. The determining feature of such systems is that the control loop contains a link of pure (or transport) delay by time T (or for the path S) of the signal at its output with respect to the signal at its input. Apart from time delay links, these systems also contain other linear elements. Such systems include both longstudied systems for transporting various materials and relatively new selflearning repetitive control systems for accurately reproducing cyclically repeated motions or other signals with a period T (or S). The stability of special linear systems can be studied with fully resting on the Nyquist frequency criterion. According to the Nyquist frequency criterion, the stability of a closedloop system is judged by analyzing the frequency transfer function (FTF) loci of the openloop system that includes the controller and the controlled object with respect to the critical point (1, j0) on the complex plane. However, in the majority of cases, the presence of transcendental links results in that the FTF loci of the openloop system have the shape of a star with infinitely long rays, which makes it difficult to interpret the stability of systems with a time delay according to the Nyquist criterion. In such cases, it is more convenient to use a group of graphic criteria, the application of which makes it possible to establish sufficient stability conditions without examining the entire openloop system (the controller plus the object) by analyzing the relative position of the controlled object frequency response loci (obtained without taking into account the controller properties) and a certain stability region boundary, which is determined by the controller properties (obtained without taking into account the controlled object properties). To date, stability region boundaries have already been found for many types of specific structures of systems with a time delay. The problem is that an individually shaped stability region boundary has to be found for each specific type of controller. It is shown, based on a structural transposition of systems with a time delay, that their stability can be studied by using almost any stability boundaries that were previously proposed for some specific types of transcendental controllers. By generalizing the criteria it will be possible not only to estimate for the first time the stability of systems with a time delay in combination with a linear part of an arbitrary kind, but also to expand the variety of applied types of transcendental controllers.

Methods for measuring the microwave permittivity and permeability of materials are considered. The specific features and applicability conditions of measurement methods in transmission lines and in free space are shown, and the measurement errors are analyzed along with the calibration procedures applied for reducing the errors. Individual sections of the articles contain descriptions of scalar, resonance, quasistatic, and quasioptic methods. It has been determined that out of many existing techniques, the NicolsonRossWeir measurement method in a coaxial line and also the method for measuring the permeability of thin ferromagnetic films with the use of a shortcircuited strip cell are most widely applied. By using these methods, the majority of matters concerned with studying the microwave properties of materials can be solved.
«Cinque difficoltà per chi scrive la verità» di Bertolt Brecht: un contributo alla riflessione teorica e storica su letteratura e totalitarismo
Authors: Grazzini Serena
Published: December 2020

"After the fall of the Berlin Wall, numerous
research projects were devoted to better
understanding the organization of political, social,
economic and cultural life in totalitarian regimes.
In the German-speaking area, the reflection has
often been conducted through a more or less
close comparison of the National Socialist and
the East German Socialist states. In the first part
of the issue I discuss the potential and limits of
this juxtaposition. In the second part I propose
a close reading of Bertolt Brecht’s paper “Fünf

"Matei Vișniec was exiled in Western
Europe before the fall of the totalitarian regime
in his native country, Romania. The traumas of
his life experience have left an important mark in
the writer’s conscience as a result of which, after
becoming a well-known Francophone writer,
he started to denounce this terror in his plays,
notably the trilogy that constitutes “the trial of
communism through theatre”. This article draws
attention to Vișniec’s ethical attitude, the writing
techniques utilized in the trilogy and the way in

Kinesio Taping Use for the Prevention and Treatment of Sports Injuries in Athletes
Authors: Gligor Șerban , Gligor Răzvan
Published: December 2020

"Kinesio taping (KT) is a simple, cost-effective, affordable and safe rehabilitation method that is currently used for enabling natural healing, as it ensures local support and stability, and corrects joint position, helping athletes to quickly recover after minor or even major injuries, and to increase their athletic performance. KT helps weakened muscles, improves local blood and lymph flow, reduces pain, removes the abnormal tension accumulated at the muscle level, alleviates muscle fatigue associated to exercising and decreases the exercise-related disruption of dynamic balance. All these effects contribute to the post-injury recovery of athletes. KT is frequently used in the acute postoperative recovery after the reconstruction of the anterior cruciate ligament, in conjunction with the rehabilitation program, as it reduces edema and pain, and increases the range and force of movement. Another frequent use of KT is in patellar tendinopathy and in reducing the risk of injury as a result of balance impairment produced by muscle fatigue. The effect of KT on the range of joint motion remains unclear, and its use is still controversial, as there are many trials that do not show any beneficial effects thereof, especially in terms of effects on muscle strength and activity, and of tendon flexibility.

Keywords: kinesio taping, rehabilitation, athletes, recovery, sport performance."
The Administrative Organisation of Present Cluj County between 1541 and 1848

Published: December 2020

"The Administrative Organisation of Present Cluj County between 1541 and 1848. The administrative organisation is one of the most important spatial planning actions, because it directly determines spatial configurations and polarizing relations, while concentrating local government institutions into cities and towns which are becoming more prominent as a result of them being designated as administrative centres. This paper attempts to reconstruct the administrative divisions and the ranking of settlements of present Cluj County between 1541 and 1848. Included almost entirely in the Principality of Transylvania, the area of present Cluj County was mainly covered, from North to South, by the counties of Solnocu Interior (Inner Solnoc), Dăbâca, Cluj and Turda. The Szekler seat of Arieș covered a small part in the South and Bihor County (in the Kingdom of Hungary) covered a very small part in the West of present Cluj County. Their limits remained largely the same over a very long period of time. The counties of Solnocu Interior, Dăbâca, Cluj and Turda extended a lot to the West and East of present Cluj County, but their seats were all located here: Dej (Solnocu Interior County), Bonțida (Dăbâca County), Cluj and Turda, to which one may add Gherla, that had the highest status, just like Cluj, that of free royal city, and had an administration of its own. All counties were divided into two districts, an Upper District and a Lower District, and the districts, in their turn, were further divided into circles (smaller districts). Cluj, Gherla, Turda and Dej have retained their importance throughout several centuries up until today, and their historical heritage and prominence still plays an important part in the present regional framework.

Keywords: Cluj County, administrative organisation, historical counties, districts, Principality of Transylvania."

(«We must run. Everyone is running.» (M.A. Bulgakov and N.A. Teffi))
Authors:   (Institute for Slavic Studies of the Russian Academy of Sciences, Yablokov Evgeny
Published: December 2020

«We must run. Everyone is running.» (M.A. Bulgakov and N.A. Teffi) The subject is new in literary criticism, the question of the influence of Teffi's works on Bulgakov's work has not yet been raised. The article analyzes Teffi's stories and feuilletons of 1918–1919, the period of the writer's stay in Kiev and Odessa, as well as her memoirs in 1931; and there are parallels between Teffi's image of Kiev in 1918 and Bulgakov's novel The White Guard. Special attention should be paid to the “running” motif, relevant in Teffi's work in the late 1910s, and which is developed in Bulgakov's play The Flight. Moreover, this play was influenced by the theme of Constantinople in Teffi's journalism during the first months of her exile. In connection with the insect motives of the play The Flight, we find the discourse of the “cockroach” in a certain number of works by Teffi, notably in Potapovna. For the writer, one of the important problems is the essence of the concept of “human”, a problem then developed by Bulgakov in Heart of a Dog, which is a variant of the “humanoid” creature that appeared in the work of Teffi in the late 1900s.

The I’s of the Informant: Memoirs of Surveillance Society
Authors: Szpunar Piotr M.
Published: December 2020

The informant is both a controversial medium of security and a maligned cultural figure. Their actions and stories about their actions are integral nodes in the economy of fear that structures surveillance society. This paper examines how Cold War and war on terror informants tell stories about themselves (Budenz 1947; Speckhard and Shaikh 2014) against the backdrop of a “fear of small numbers” (Appadurai 2006) on the home front. The overlapping intentions (confession, memoir, apology) and I’s (narrated, narrating, and ideological) in their memoirs provide an entry point for assessing how informants assert their authority and how they reproduce the security cultures in which they find themselves. Each memoir draws on ideological pairings central to discourses of infiltration and radicalization, respectively. The authors confess to having been the duped or radicalized westerner but narrate from the position of the patriotic Catholic or “good Muslim.” Ultimately, I argue that the narrative and ideological climax of the memoirs lies in how the transformation from enemy to friend is presented: as the result of a chance encounter. This shifts the fear of small numbers from the one amongst us who might become a traitor to the slim and incalculable probability through which one returns from extremism, which is by definition less than one. Marked as the exception, the narrative reinforces the necessity of the informant in security practices.
The Implications of Digital Employee Monitoring and People Analytics for Power Relations in the Workplace
Authors: Manokha Ivan
Published: December 2020

Jeremy Bentham’s panopticon prison project was based on three central assumptions: the omnipresence of the “watcher”; the universal visibility of objects of surveillance; and the assumption, by the “watched,” that they are under constant observation. While the metaphor of the panopticon, following Michel Foucault’s work, was often applied to workplace and workplace surveillance to highlight the “disciplining” power of the supervisor’s “gaze,” this paper argues that it is only with the recent advent of digital employee monitoring technology that the workplace is becoming truly “panoptic.” With modern electronic means of surveillance, the supervisor is always “looking”—even when not physically present or not actually watching employees—as all worker actions and movements may now be recorded and analyzed (in real time or at any time in the future). This paper argues that the modern workplace approximates Bentham’s panoptic prison much more than the “traditional” workplace ever did and examines the implications of this fundamental historical change in the paradigm of employee monitoring for power relations in the modern workplace.

El oso de anteojos Tremarctos ornatus es el único representante de la familia Ursidae en Suramérica. En la región amazonas fue visto a través de cámaras ocultas en el Área de Conservación Privada Hierba Buena-Allpayacu, de la comunidad campesina de Corosha. Donde hasta ahora, solo se ha observado a un individuo con ese pelaje además esta especie está catalogado como vulnerable según la Unión Internacio- nal para la Conservación de la Naturaleza (UICN). Sobre la base de este contexto este estudio presenta resultados de la valorización social de oso de anteojos en las rutas de las cataratas de Yurumarca, San Pablo y Cuispes. Dando como resultado que el 30% de las personas sacrifican al oso de anteojos por diversión y esto se ve influenciado por el nivel de educación. Asi mismo en las rutas de las cataratas se evidenció la presencia de oso de anteojos de tamaño grande en un 70 % en la población de Yurumarca, y en un 64% en San Pablo, mientras tanto en Cuispes 67%. El oso de anteojos se ve afectado por las perso- nas que se dedican a la ganadería para salir en defensa de sus animales sin embargo otros realizan sacrificios por diversión o para usos en medicina.

La presente investigación se realizó con el objetivo de desarrollar un protocolo para el establecimiento y ensayos preliminares de propagación in vitro de zarzamora silvestre (Rubus sp.) con potencial agroindustrial proveniente del Centro Poblado San Salvador, región Amazonas. Se identiﬁcaron plantas de zarzamora silvestre que tenían parámetros de interés agroindustrial, y a partir de estas plantas se evaluó soluciones desinfectantes para el establecimiento de yemas axilares, posteriormente se evaluó diferentes concentraciones de reguladores de crecimiento giberelinas, auxinas y citocininas para optimizar la propagación in vitro de zarzamora silvestre. Los resultados mostraron que el empleo de AG3 0,1 mg/L más kinetina 0,04 mg/L fueron las concentraciones adecuadas para el crecimiento y desarrollo de yemas axilares de zarzamora silvestre. Asimismo, el empleo de 1 o 2 mg/L de AIB en el medio de cultivo de enraizamiento, se obtuvo el mayor número de raíces y porcentaje de inducción de raíces adventicias en los brotes, resultados que permitirán tener un protocolo para la propagación vegetativa de esta especie silvestre de importancia económica.
Método mnemotécnico de evangelización bilingüe en la Doctrina christiana en la lengua guasteca con la lengua castellana de 1571
Authors: López Elvia Estefanía
Published: December 2020

El presente artículo propone el estudio de un método mnemotécnico de evangelización bilingüe registrado en la Doctrina christiana en la lengua guasteca con la lengua castellana de la orden de los agustinos publicada en 1571, con la finalidad de profundizar en el bilingüismo como estrategia de los religiosos para agilizar el proceso de evangelización en Nueva España. La metodología parte del análisis material, la semiótica de la imagen y la biblioiconografía para analizar quince grabados xilográficos presentes en dicha doctrina, que fueron diseñados según un modelo didáctico medieval, con la innovación de que en el caso que aquí se estudia se trata del registro de dos lenguas que coexistieron durante el siglo XVI: el español y el huasteco. El planteamiento principal de este artículo consiste en la imagen como fundamento de la didáctica de la enseñanza de la doctrina cristiana, con un método mnemotécnico bilingüe que permitió a los nativos americanos memorizar los principios de la fe católica en su propia lengua.

Fluorescent nanodiamonds (NDs) are carbon-based nanoparticles with various outstanding magneto-optical properties. After preparation, NDs have a variety of different surface groups that determine their physicochemical properties. For biological applications, surface modifications are crucial to impart a new interphase for controlled interactions with biomolecules or cells. Herein, a straight-forward synthesis concept denoted "adsorption-crosslinking" is applied for the efficient modification of NDs, which sequentially combines fast non-covalent adsorption based on electrostatic interactions and subsequent covalent cross-linking. As a result, a very thin and uniform nanogel coating surrounding the NDs is obtained, which imparts reactive groups as well as high colloidal stability. The impact of the reaction time, monomer concentration, molecular weight, and structure of the cross-linker on the resulting nanogel shell, the availability of reactive chemical surface functions and the quantum sensing properties of the coated NDs has been assessed and optimized. Post-modification of the nanogel-coated NDs was achieved with phototoxic ruthenium complexes yielding ND-based probes suitable for photodynamic applications. The adsorption-crosslinking ND functionalization reported herein provides new avenues towards functional probes and traceable nanocarriers for high resolution bioimaging, nanoscale sensing and photodynamic applications.
