Efficient Characterization of Quantum Evolutions via a Recommender System
Authors: Batra Priya , Singh Anukriti , Mahesh T. S.
Published: December 2021

We demonstrate characterizing quantum evolutions via matrix factorization algorithm, a particular type of the recommender system (RS). A system undergoing a quantum evolution can be characterized in several ways. Here we choose (i) quantum correlations quantified by measures such as entropy, negativity, or discord, and (ii) state-fidelity. Using quantum registers with up to 10 qubits, we demonstrate that an RS can efficiently characterize both unitary and nonunitary evolutions. After carrying out a detailed performance analysis of the RS in two qubits, we show that it can be used to distinguish a clean database of quantum correlations from a noisy or a fake one. Moreover, we find that the RS brings about a significant computational advantage for building a large database of quantum discord, for which no simple closed-form expression exists. Also, RS can efficiently characterize systems undergoing nonunitary evolutions in terms of quantum discord reduction as well as state-fidelity. Finally, we utilize RS for the construction of discord phase space in a nonlinear quantum system.
El derecho a una muerte digna en Colombia nos concierne a todos
Authors: Quintero -Cusguen Patricia
Published: December 2021

INTRODUCCIÓN:
Tener conocimiento sobre el derecho fundamental a la muerte digna en Colombia es necesaria para los especialistas en neurología, que se enfrentan a personas con enfermedades crónicas, degenerativas, avanzadas e incurables.

OBJETIVO:
Realizar una reflexión acerca de la muerte digna en Colombia a partir del marco jurídico, bioético y médico.

MÉTODOS:
Se realizó una revisión de las publicaciones desde 1992 hasta el presente año sobre el derecho a la muerte digna en Colombia, a partir de la observación cronológica de las sentencias de la Corte Constitucional, así como de los aspectos bioéticos y médicos del fin de vida.

RESULTADOS:
El derecho fundamental a la muerte digna, el cual es posible a partir de la Constitución de 1991, es un proceso inacabado por la emergencia de nuevos derechos amparados por la Corte Constitucional y el Poder Judicial. La protección de la dignidad de las personas se debe proteger a lo largo de toda la existencia, y esta incluye la muerte. Este derecho es multidimensional, no excluyente, y abarca el cuidado paliativo, la adecuación terapéutica y la eutanasia activa.

CONCLUSIÓN:
La muerte digna es un derecho fundamental, emergente multidimensional, que requiere del conocimiento de los neurólogos de los aspectos jurídicos y bioéticos.
O massacre dos “Nativos” do Arapuim na luta pelo reconhecimento do território quilombola no norte de Minas Gerais
Authors: Silva Greiciele Soares da , Barbosa Rômulo Soares
Published: December 2021

Este trabalho busca discutir o processo de violação dos direitos e a busca por justiça vivenciada pela comunidade dos Nativos do Arapuim, no município de Verdelândia no Norte de Minas Gerais. Uma das estratégias de luta é o acionamento da identidade quilombola, que representa uma categoria analítica e jurídica, permitindo aos Nativos estabelecer um diálogo com o Estado, tendo como finalidade a garantia e legitimação de seus direitos. O grupo social dos Nativos do Arapuim é formado por pessoas descendentes dos posseiros e camponeses que foram expulsos e desterritorializados nos anos de 1960, no emblemático conflito conhecido como “Massacre de Cachoeirinha”, ocorrido no antigo povoado de Cachoeirinha, e que atualmente é o município de Verdelândia. Este trabalho apresentado é resultado da pesquisa e construção do projeto de dissertação de mestrado, e para o desenvolvimento de tal estudo, foram realizados os seguintes procedimentos metodológicos: trabalho de campo com observação direta e entrevistas com lideranças políticas da comunidade, revisão bibliográfica e pesquisa documental.

Published: December 2021

Este artigo apresenta o resultado de uma pesquisa na qual se analisou de que maneira o uso de conteúdos de Astronomia, trabalhados em aulas de Filosofia podem auxiliar na análise crítica dos estudantes do Ensino Médio sobre a existência, com enfoque na pequenez humana. Em uma abordagem interdisciplinar, tratou-se da relação entre Astronomia e Filosofia como áreas afins para uma reflexão existencialista. A abordagem culminou na criação de conceitos sobre a condição humana na Terra e no Cosmo. A metodologia utilizada utilizou questionários, relatos verbais e escritos e anotações do pesquisador-professor. A análise do itinerário da criação de conceitos pelos dos alunos validou a proposta mostrando que a intangibilidade da Filosofia foi assimilada por meio de conteúdos de Astronomia. As reflexões sobre a existência humana caminharam para a análise de nossa condição de pequenez diante da realidade terrena e cósmica.
Poetics and Textual Analysis of Dostoevsky’s Novel The Adolescent in the Studies of Russian Authors of the 1920s-1940s
Authors: Bogdanova Olga A.
Published: December 2021

In the 1920s–1940s poetics became the main aspect of the study of The Adolescent both in the USSR and in Russian emigration. Of particular importance is the work on the handwritten corpus of the novel. The review examines the publications of the surviving manuscripts and the main studies devoted to their analysis. The stages of poetics studies and textual criticism on The Adolescent are traced in chronological order. The review consists of three sections: studies on the poetics and textual studies of The Adolescent in 1920s USSR (L.P. Grossman, N.P. Antsiferov, R.V. Ivanov-Razumnik, V.L. Komarovich, M.G. Davidovich, B.M. Engelgardt, S.A. Askoldov, S.N. Durylin, M.M. Bakhtin); Russian emigration about the poetics of The Adolescent in 1920s-1940s (I.I. Lapshin, R.V. Pletnev, A.L. Bem, P.M. Bicilli, K.V. Mochulsky); studies on the poetics of The Adolescent in 1930s-1940s USSR (G.I. Chulkov, A.S. Dolinin). The main issues that occupied Soviet and emigrant scholars of the 1920s and 1940s are highlighted: the ideological and artistic continuity of the novels The Devils, The Adolescent, and The Brothers Karamazov as the development of the idea of the plan for The Life of a Great Sinner; Dostoevsky’s creative method in the novel The Adolescent; the creative history and type of the novel; plot-compositional features and narrative strategies; motives and symbols; typology and characterology of heroes, including reminiscences from Griboedov and Pushkin, artistic polemics with L.N. Tolstoy and “duality”; prototypes of characters; speech style. The chapter on the novel in the book Dostoevsky. Life and Works by the emigrant scholar K.V. Mochulsky (1947) is recognized as the pinnacle of the study of The Adolescent in the first half of the 20th century, as it absorbed practically the entire research discourse on both sides of the USSR border and gave a complete picture of its problems and poetics. At the same time, the book is free from the traces of ideological coercion that Soviet scholars experienced in the 1930s and 1940s.
The Italian Reception of Dostoevsky’s Novel The Adolescent
Authors: Corbella Caterina
Published: December 2021

The article analyses the Italian reception of Dostoevsky’s novel The Adolescent. The small number of translations of the novel in Italian, as well as the lack of critical works specifically devoted to it, indicate little interest in the book on the part of both the average Italian reader and the academic community, especially when compared to other works by Dostoevsky. The second part of the article offers an overview of the prefaces to the various editions, which are, in fact, the only works in Italian exclusively devoted to the novel.
Did Dostoevsky Unravel the Mystery of Man?
Authors: Kasatkina Tatiana A.
Published: December 2021

In his very first youth Dostoevsky defined his life program, set for himself an aim for which it would be worth living life. His program was to unravel the mystery of man, and it was consistently pursued by the writer through all his life and works. Was it a process of constant search, or did the writer find out the answer to the mystery? This is the topic of the article.
1847 Feuilletons as an “Explanatory Dictionary” of the Philosophy of Dostoevsky’s Early Works
Authors: Magaril-Il'yaeva Tatyana G.
Published: December 2021

In the article are analyzed the feuilletons written by Fyodor Dostoevsky in 1847 for the column “Peterburgskaya Letopis” in the journal “Sankt-Peterburgskie Vedomosti”, where the writer tried to present his worldview relying not on philosophical and theological concepts but on artistic images and symbols that can be found in other texts from this period. However, in the case of journal articles, these images are shown far more clearly, due to the lack of plot, and can be interpreted more easily than in those cases when they are part of the complex structure of a work of fiction. These texts can be defined as the writer’s “explanatory dictionary”, where Dostoevsky clarifies the main images and techniques of his creative work.
On the Question of “Living Life” in Dostoevsky’s Novel The Adolescent
Authors: Shalina Marina A.
Published: December 2021

The article examines the specifics of Dostoevsky’s comprehension of the phenomenon of “living life” and its correlation with the female images in the novel The Adolescent. The author assumes that the decision to name Katerina Nikolaevna Akhmakova “living life” belongs exclusively to the fantasy of Arkady, who is in love with her, carried away and blinded by the her brilliant beauty, and it does not coincide with the author’s position. Sometimes in Dostoevsky studies it is stated the vagueness of Dostoevsky’s ideas about “living life”, however, as it is proved by the numerous contexts of the use of the formula in journalism and the writer’s notebooks (including during the making of the novel The Adolescent), Dostoevsky had a very specific view of this phenomenon and associated it with the “great idea” of the immortality of the soul, and with the special maternal and messianic role of Orthodox Russia. In this regard, the article suggests that the author’s concept of “living life” is nearer to the image of the “mother” Sofia Andreevna Dolgorukaya. It is concluded that in the novel, with the help of opposition and at the same time juxtaposition of the “queen of the earth” and the “angel of heaven”, Dostoevskij creates an artistic image of the Russian woman in its dual unity: flesh, intellect (Akhmakova) and soul, heart (Sophia). The personalities of both heroines also embody Dostoevsky’s idea of “life” in its various forms: the earthly one, made of flesh, and the heavenly, made of spirit.
“Restoring the Kinship”: the Novel The Adolescent as a Prologue to the Dialogue Between Nikolay Fedorov and Fyodor Dostoevsky
Authors: Gacheva Anastasia G.
Published: December 2021

The article is an attempt to read the novel The Adolescent in the light of the spiritual and creative dialogue between the philosopher of the common task Nikolay Fedorov and Fyodor Dostoevsky. Although The Adolescent was written and published three years before Fedorov’s student N. Peterson presented his teacher’s ideas to the writer in the article “What should a people’s school be?”, the novel can be considered as a prologue to the topic that eventually became the subject of Fedorov’s main work The question of brotherhood or kinship, about the causes of the non-fraternal, unrelated, i.e. non-peaceful, state of the world, and about the means to restore kinship. The plot of the novel is interpreted in the article through the prism of Fedorov’s themes of non-kinship and the restoration of universal kinship, the idea of returning the hearts of sons to their fathers and the fathers’ ones to their children. It is shown how the theme of “family as the practical beginning of love” is expressed in the novel.
No Longer an Adolescent, Not Yet a Prince
Authors: Boborykina Tatiana A.
Published: December 2021

The essay explores some of the numerous questions which the readers of The Adolescent — one of the most enigmatic novels by Dostoevsky — face. What is the hidden meaning of the various allusions to Pushkin, Dickens, Shakespeare, which are spread all over the text? What is the encoded meaning of the novel’s specific style, its “cinematographic” visuality, and finally — what is the meaning of the very title, and why it is constantly repeated that the adolescent with a “princely” name is not a “Prince”? The path of the hero and his idea of “becoming Rothschild” is traced. The reasons for such an idea are discovered through parallels to A Christmas Carol by Dickens. The Biblical parable about the rich man and Lazarus is defined as the source of both Dickens’s story and part of Dostoevsky’s novel. The point of transformation of the adolescent’s “idea” is compared with Dostoevsky’s Christmas story The Beggar Boy at Christ’s Christmas Tree. Special attention is paid to such elements of style as the “stream of consciousness”, “internal monologue” etc., which foreshadow revelations of modernism. Cinematographic devices like “close-ups” and materialized metaphors are also in the focus of attention, as most of them visualize the leitmotifs of the novel. The analysis of the adolescent’s spiritual portrait discovers an important role of not only his “two fathers”, but also his school friend Lambert, whose grotesque and almost mythological figure is interpreted in various ways. The structure of the essay leads to the decoding of the laconic formula “Hamlet-Christian” with which Dostoevsky opens his outline and notes to the novel. The maxim is interpreted as some transcendental goal to which the author is leading his hero from the very first line of the novel’s plan. In the context of the theme “No longer an adolescent, not yet a Prince” the essay explores the metaphorical content of such notions as “adolescent” and “prince”. The research highlights that the metaphysical realm of the novel is enormous and embraces not only the path of its young hero but also the possible ways of the historical development of both Russia and Europe.

Published: December 2021

Background: This study was conducted to evaluate the surgical
results of the arterial switch operation for Taussig-Bing variants, at a
single institution in a lower-middle income country. Methods:
Between June 2010 and December 2018, all consecutive patients diagnosed
with Taussig-Bing variants who underwent the arterial switch operation
and ventricular septal defect closure were included in the study.
Results: A total of 72 patients of Taussig-Bing variants who
underwent arterial switch operation and ventricular septal defect
closure. There were 10 early deaths (13.9%) and 2 late deaths (2.8%).
Intraoperative ventricular septal defect enlargement [hazard ratio
(HR) 7.23, 95% confidence interval (CI) 3.1294-16.7167; P
< 0.001], secondary aortic cross clamping (HR 28.38, 95% CI
4.8427-166.3484; P < 0.001), post-operative pneumonia
(HR 5.64, 95% CI 1.2724-24.9917; P = 0.023), and post-operative
sepsis (HR 5.28, 95% CI 1.3512-20.6553; p = 0.017) were risk factors
for overall mortality by competing risk analysis. Sixty patients
(83.3%) required septoparietal trabeculation division/resection during
the arterial switch operation in an attempt to avoid right ventricular
outflow tract obstruction. The reoperation rate for right ventricular
outflow tract obstruction at last follow up was 6% (3 patients). The
estimated freedom from reoperation for right ventricular outflow tract
obstruction at 1 year, 5 year and 9 year was 98.3%, 91.9% and 91.9 ,
respectively. Conclusions: The results of arterial switch
operation for Taussig-Bing variants were satisfactory in the operative
setting of a lower-middle income country, and performing extensive
septoparietal trabeculation division might reduce the reintervention
rate for right ventricular outflow tract obstruction in these patients.
Universal Subsidized Continuous Glucose Monitoring Funding for Young People With Type 1 Diabetes: Uptake and Outcomes Over 2 Years, a Population-Based Study
Authors: Johnson Stephanie R. , Holmes-Walker Deborah J. , Chee Melissa , Earnest Arul , Jones Timothy W.
Published: December 2021

OBJECTIVE

Continuous glucose monitoring (CGM) is increasingly used in type 1 diabetes management; however, funding models vary. This study determined the uptake rate and glycemic outcomes following a change in national health policy to introduce universal subsidized CGM funding for people with type 1 diabetes aged <21 years.

RESEARCH DESIGN AND METHODS

Longitudinal data from 12 months before the subsidy until 24 months after were analyzed. Measures and outcomes included age, diabetes duration, HbA1c, episodes of diabetic ketoacidosis and severe hypoglycemia, insulin regimen, CGM uptake, and percentage CGM use. Two data sources were used: the Australasian Diabetes Database Network (ADDN) registry (a prospective diabetes database) and the National Diabetes Service Scheme (NDSS) registry that includes almost all individuals with type 1 diabetes nationally.

RESULTS

CGM uptake increased from 5% presubsidy to 79% after 2 years. After CGM introduction, the odds ratio (OR) of achieving the HbA1c target of <7.0% improved at 12 months (OR 2.5, P < 0.001) and was maintained at 24 months (OR 2.3, P < 0.001). The OR for suboptimal glycemic control (HbA1c ≥9.0%) decreased to 0.34 (P < 0.001) at 24 months. Of CGM users, 65% used CGM >75% of time, and had a lower HbA1c at 24 months compared with those with usage <25% (7.8 ± 1.3% vs. 8.6 ± 1.8%, respectively, P < 0.001). Diabetic ketoacidosis was also reduced in this group (incidence rate ratio 0.49, 95% CI 0.33–0.74, P < 0.001).

CONCLUSIONS

Following the national subsidy, CGM use was high and associated with sustained improvement in glycemic control. This information will inform economic analyses and future policy and serve as a model of evaluation diabetes technologies.

Persistências Fanonianas no Século XXI
Authors: Miranda Cerqueira Greice Quelen
Published: December 2021

Um dos maiores problemas, no que tange a população negra ainda hoje, é a fuga de sua historicidade para passar por um processo de afirmação e ser reconhecido pelo homem ou mulher branco e branca. O uso de máscaras, que disfarçam essas características, continuam a ser empregadas, sendo vistas como uma tentativa de aproximar-se de uma raça que muitas vezes se coloca numa posição de universalidade ontológica. Dito isso, o presente ensaio visa apresentar uma das problemáticas contida no livro Pele Negra, Máscaras Brancas de Frantz Fanon. Desse modo, aborda-se como conteúdo o conceito de reconhecimento, explanado pelo autor, como um contraponto a Hegel. Seguido por uma explanação de como o negro é colocado na zona do não-ser, por meio da falta desse reconhecimento que é universalizado pelo branco. Apresentando ainda de que maneira esse lugar não-ontológico ainda persiste no século XXI, com a permanência de instituições racistas e a dificuldade de ascensão social da pessoa preta. O que, por fim, conduz para as vias de solução que podem ser apresentadas: como a retirada da posição universal e a intersecção entre corpo e mente.
Pannonian (late Miocene) ostracod fauna from Pécs-Danitzpuszta in Southern Hungary

Published: December 2021

The large outcrop at Pécs-Danitzpuszta, southern Hungary, exposes a 65-meter-thick succession of calcareous marls, clay marls and calcareous sands that were deposited during the early history of Lake Pannon, a vast, Caspian-type lake in Central Europe in the late Miocene. Within the framework of the complex stratigraphic investigation of this succession, well preserved, relatively diverse benthic ostracod assemblages containing 39 taxa were recovered from 29 samples (16 samples were barren). Palaeoecological interpretation of the ostracod genera suggests that deposition took place in a low-energy environment, in the shallow sublittoral zone of Lake Pannon, in pliohaline (9–16‰ salinity) water. The entire succession was divided into four interval zones based on the first occurrences of assumedly useful marker fossils: Hemicytheria lorentheyi Zone (from sample D29), Hemicytheria tenuistriata Zone (from sample D17), Propontoniella candeo Zone (from sample D115) and Amplocypris abscissa Zone (from sample D209). Based on comparison to the Beočin section 150 km to the SE, where a lithologically and stratigraphically similar section was dated magnetostratigraphically by an international team, we tentatively assume that the Pannonian marl succession of the Pécs-Danitzpuszta outcrop represents the time interval of 11.6 to ca. 10 Ma.

Published: December 2021

In a Microgrid system that relies on renewable energy generation, one of the most important constituent systems is the Battery Energy Storage System because of its vital role in maintaining the stability of the Microgrid in providing power to the load. However, to operate the battery, a Battery Management System is needed to ensure the battery operates at the desired working range, so that battery reliability can be maintained. To determine the behavior of the Microgrid and the designed BMS in accordance with the desired specifications, a Hardware-inthe-Loop (HIL) Simulation has been designed using Simulink to model a DC Microgrid which consists of several sub-systems such as: An ideally designed generator and load as a tester, a bidirectional buck and boost converter with a PI controller, and a battery system equipped with a Switched Shunt Resistor Cell Balancing type, all controlled using the BMS algorithm implemented on Arduino. From the test results, it is found that HIL can communicate with good QoS on various inputs as long as the Arduino sample time meets. Then the PI controller with HIL was able to improve converter performance and also succeeded in controlling cell balancing with the efficiency of charging and idle modes of 99% and 99.4% respectively. Finally, in testing the integrated system, the BMS can maintain the performance of the Microgrid with bus voltage and battery current parameters in various SoC conditions and generator voltage fluctuations, even though there are high voltage transients.

The study of service quality and clients’ satisfaction has been used by organisations to deliver better services to their clients. While many studies have been done on this topic from the perspective of the public towards the government service, there were few emphases from the perspective of the government servants (G2G) towards the government services offered by other government agencies. This study aimed to investigate the relationship between service quality and clients’ satisfaction among employees at a government agency towards counter services at Urban Transformation Centre (UTC) Kuching, Sarawak. The study includes all five elements of Service Quality Dimensions (SERVQUAL) which were Tangible, Reliability, Responsiveness, Assurance, and Empathy. This study includes all employees of a government agency in Kota Samarahan, Sarawak. Questionnaires were distributed to respondents through Google Form with a returned rate of 88%. It was found that empathy and responsiveness variables had a strong and positive correlation with Clients’ Satisfaction while Assurance, Reliability, and Tangibility had a moderate and positive correlation with Clients’ Satisfaction. These findings implied that clients were more satisfied with services that were handled with care and discretion as well as quickly resolving unexpected issues thus providing insights to government agencies to improve their services.

Bolstering Transformation Delivery through Employee Engagement and Innovative Work Behaviour in Malaysia Public Services: A Conceptual Paper
Authors: Ahmad Fadzil Ahmad Syahmi , Hassan Roshidi , Shaari Nur Fatihah , Zainoddin Amir Imran
Published: December 2021

The debut of National Transformation 2050 validates that Malaysia is committed in standing tall amongst the developed nations. Over the years, numerous transformation programs have been introduced to enhance the wellbeing of the nation and its people. Among the agenda is to overcome challenges in public services delivery which include the improvement of services by the counter service team and frontliners as well as the enhancement of reliability and integrity, issues of productivity, and many more. Public servants are an important source of innovation for an organisation that needs to be continuously nurtured. To accelerate the outcome, engagement was reportedly found to be the key enabler for sustainable success in any change or transformational-related event. Fostering employee engagement will nurture many prodigious advantages such as augmenting people’s innovative mindset and will greatly enhance the likelihood for a successful transformation program to happen. Along with the derivation of theoretical concepts guided by Social Exchange Theory (SET), the proposed concept is further reinforced through the best practices obtained from developed countries that have adapted best practices in employee engagement and innovation. The critical key area to a developed nation is always the wellbeing of its public services. In shaping Malaysia to be one of the most prominent figures in the future, everyone needs to be a builder.

PSYCHOLOGICAL RESOURCES OF THE PERSONALITY OF LAW ENFORCEMENT AGENCIES AT THE STAGE OF PROFESSIONAL TRAINING
Authors: Sashurina Elena , Larionov Stanislav
Published: December 2021

The social demands and expectations regarding the work of law enforcement agencies have never been so high as now; the surrounding society wants to see professional and humane police officers and to feel the effectiveness of their professional activities. The system of law enforcement agencies in recent years is in a state of permanent transformation, that is what aggravates the problem of quality training of its staff. It lies in the fact that, first, there are not enough applicants for the service, and second, the available candidates mostly do not fully correspond to the established decision criterion. This orients managers and practical psychologists of the Ministry of Internal Affairs to find and improve the ways to support and develop staff, to keep them in the workplace; it also focuses on the realization that employees are important and have potential opportunities and resources for self-development. The professional development of law enforcement agencies usually begins in departmental higher educational institutions, which determines the relevance of the study of psychological resources of the law enforcement agency`s personality at the stage of professional training and defines the aim of the current article. The complex of theoretical and empirical search methods was used during the study, in particular the method “Psychological Narrative Analysis of Crisis / Traumatic Events” developed by V. I. Shebanova. The sample consisted of 84 future law enforcement agencies who study and serve at the Kharkiv National University of Internal Affairs. The study identified the main significant events in the life and attitude of law enforcement agencies at the teaching stage in the higher educational institutions with specific conditions. It is found that they can be divided into seven categories, in which there are important events common to military students: school; training and service activities in the higher educational institutions; family; difficult life events; losses; personal relationships; etc. It is determined that the most important life events happened to military students in the life period before entering higher educational institutions, which should focus on finding resources in psychological support to the autobiographical narrative of the individual. The range of military students' psychological resources is identified, including emotional experiences of pleasant events, interaction with significant relatives, “adult” reassessment of situations and positive thinking, finding new connections and contacts, awareness of target requests and the impact of events on the future.

Published: December 2021

Estudo de caso que examina o tratamento que os clássicos da literatura recebem nas bibliotecas públicas de Porto Alegre. Propõe definições de clássicos com base na teoria literária. Conceitua a biblioteca pública como instituição que deve prover gratuitamente cultura, educação, lazer e informação para a população. Relaciona o conceito de clássico com essas funções e afirma a necessidade de divulgação especial do cânone ocidental nessas instituições. Pesquisa a divulgação que os clássicos recebem nas bibliotecas públicas em Porto Alegre, por meio de entrevistas estruturadas com os bibliotecários-chefes e observações sistemáticas, individuais e não participantes dos espaços físicos e ambientes virtuais das unidades. Conclui que a divulgação da alta literatura pelas bibliotecas é muito limitada, devido a uma série de fatores, destacando-se a falta de investimentos do poder público por parte do Governo do Estado e a carência de conhecimento dos clássicos e do seu potencial junto ao público por parte dos responsáveis pelas unidades.

Published: December 2021

The current work investigates the behavior and strength of T-shaped cross section ring deep beams through a Finite element parametric study. Currently, ring diameter, loading type, concrete compressive strength and number of supports are taken into consideration. It is found that increasing ring diameter of beam by 12.5-25% leads to increase the maximum positive moment, maximum negative moment, maximum torsional moment and midspan deflection by 1.1-2.2%, 2.2-4.3%, 3-6% and 16-33%, respectively, while the load ultimate capacity increases by 11-17%. The positive and torsional moments at midspan and midspan deflection decrease by 23-36%, 3-11% and 6-14%, respectively when the loading type varies from concentered to full uniformly load over a span length of 33, 50, 67 and 100%, respectively. In a related context, this change in load type leads the negative moment at support and the load ultimate capacity to increase by 2-21% and 6-85%, respectively. The midspan positive moment, negative moment, torsional moment and load ultimate capacity increase by 20.4-71.3%, 20-69.7%, 15.6-43.8% and 21-73%, respectively, whereas deflection decreases by 1.4-11%, when increasing the compressive concrete strength by 45-190%. Finally, it is found that the load ultimate capacity increases by 82-348%, when number of supports increases by 25-100%, while torsional moment, maximum positive moments, maximum negative moments and midspan deflection decrease by 11-50%, 38-76.4%, 38.6-76.8% and 14-39%, respectively due to this increase in the number of supports.

Antecedents: Motivation for using social networks helps to understand the online behaviors of the adult population and can be a relevant predictor of several variables, considering its common usage on a daily routine. Objective: This article aimed to seek evidence of validity and accuracy for the Social Media Motivations Scale (SMM-S) in the Brazilian context and understand its relationship with personality and life satisfaction. Method: The research was carried out in two stages, with 600 adults in each one, users of online social networks. In both samples, most were women with higher education, from all Brazilian regions and pointed Instagram as their favorite online service. Results: Results indicated that the adapted version of the Social Media Motivations Scale presented indicators of validity and reliability for a structure of four dimensions: Freedom in Social Networks, Routine in Social Networks, Identity in Social Networks and Social Maintenance. Correlations with life satisfaction and personality revealed evidence of convergent validity. Conclusion: The instrument showed validity psychometric evidences for the Brazilian context. The article presents a discussion of the motivations for social networks usage in different contexts.

Published: December 2021

Let S be a domain and R = S[t; σ, δ] a skew polynomial ring, where σ is an injective endomorphism of S and δ a left σ -derivation. We give criteria for skew polynomials f ∈ R of degree less or equal to four to be irreducible. We apply them to low degree polynomials in quantized Weyl algebras and the quantum planes. We also consider f(t) = tm
− a ∈ R.

The paper argues that Swedish preschool teachers tend to be depicted mainly as subjects for policy implementation when it comes to their mission to teach in preschool. Taking the perspective of inside-out-professionalism, the paper aims to make visible how preschool teachers have developed professional knowledge about teaching from within the preschool context. The methodology is based on content analysis of semi-structured interviews with ten experienced preschool teachers. Teaching is defined openly as a conscious arrangement for learning. Dewey’s notions of experience, environment and subject content further informed the interpretation of the results. Two main categories were discerned, both emphasising the experience and active participation of the child: identifying potential subject components in children’s experience, and arranging an environment in which the child becomes a part. Each main category further included two sub-categories. Thus the present issue of implementing teaching in preschool could gain from research on established preschool practice based on inside-out-professionalism and made visible through Dewey’s theorical lens.

The increasing production of hormone estrogen and progesteron during pregnance known as a risk factors of periodontal disease during pregnance. The other risk factor of periodontal disease during pregnance is obesity, because adipose tissue in obesity person produce pro inflamatory cytokines that influence periodontal status. Both of this risk factors could happen in pregnance woman. During pregnancy, production of hormones estrogen, progesteron and the weight is gained. The aim of this study was to evaluate the relationship between weight during pregnance with periodontal status. This research was an observational analytic with crossectional comparative, with 52 sampels. CPI indeks was used to evaluate the periodontal status meanwhile weight during pregnance was measured by GWS IOM. The resulting data were analyzed by chi-square test. There were significantly differences between pregnance weight at trimester 2nd and 3rd with increasing of the Community Periodontal Indeks.
