The role of CRP in the diagnosis of postoperative complications in rectal surgery
Authors: Řezáč Tomáš , Stašek Martin , Zbořil Pavel , Špička Petr
Published: July 2021

Postoperative complications of rectal resections classified as grade III or higher according to Clavien-Dindo system, which also include anastomotic leaks, are usually life-threatening conditions. Delayed diagnosis may account for almost 18% of deaths. Due to nonspecific clinical signs in the early postoperative period, diagnosing these complications may truly be a challenge for clinicians. Nowadays, with the implementation of the ERAS protocol (enhanced recovery after surgery) and efforts concentrated on quickly delivered treatment to patients suffering from the above-mentioned complications, an appropriate marker with high specificity is required. Postoperative levels of C-reactive protein in blood serum seem promising in this aspect.

The presented study aimed to determine the cut-off level of serum C-reactive protein as a possible predictive factor for early diagnosis of serious postoperative complications associated with rectal resections. This could also lead clinicians to the diagnosis of anastomotic leak after other possible options are ruled out.

This study is a retrospective observational analysis of patients who underwent open resection of rectal cancer during a one-year period. Collected data included risk factors (age, gender, BMI, bowel preparation), record of complications and C Reactive Protein (CRP) serum levels.

The study included 162 patients. Uncomplicated postoperative course was observed in 58 patients (35.8%). Complications were present in 104 cases (64.2%), including surgical site infections (16.7%) and anastomotic leak (9.9%). The mortality rate was 2.5%. Serum CRP threshold predicting relevant complications reached a sensitivity of 83.3% and specificity of 82.7% on POD 4, with a 175.4 mg/L cut-off value, burdened with a 95.7% negative predictive value.

Postoperative serum C-reactive protein may be used as a good predictor of infectious complications, including anastomotic leaks. Measuring CRP levels in the early postoperative period may facilitate identification oflow-risk patients ensure early and safe discharges from hospital after rectal resections.

Published: July 2021

Supernovas são explosões super luminosas que caracterizam o fim da vida de uma estrela supermassiva. Redes Neurais Artificiais são ferramentas promissoras para a automação da análise dos dados de supernovas provenientes de telescópios, porém, apresentam uma desvantagem, que é a grande demanda por recursos de hardware necessários para sua implementação. Neste trabalho, propõe-se uma Rede Neural Convolucional otimizada para Detecção de Supernovas em imagens, utilizando a técnica de poda dos parâmetros. O algoritmo obteve uma acurácia de 0,964 e a poda foi capaz de reduzir o tamanho do modelo em até 70%, sem perda significativa de acurácia.

Addressing search in scientific open data repositories: A semantic metasearch platform
Authors: Borges Gustavo Caetano , Reis Julio César dos , Medeiros Claudia Bauzer
Published: July 2021

Scientific research in all fields has advanced in complexity and in the amount of data generated. The heterogeneity of data repositories, data meaning and their metadata standards makes this problem even more significant. In spite of several proposals to find and retrieve research data from public repositories, there is still need for more comprehensive retrieval solutions. In this article, we specify and develop a mechanism to search for scientific data that takes advantage of metadata records and semantic methods. We present the conception of our architecture and how we have implemented it in a use case in agriculture.
Combate ao Covid19: Detecção em tempo real de indivíduos sem máscara em ambiente escolar por meio de Deep Learning
Authors: Figueiredo Elaine Barbosa , Silva Eliana Pereira da
Published: July 2021

Doenças respiratórias como o COVID19 são transmitidas por vias aéreas, principalmente em ambientes onde pode ser difícil manter o distanciamento físico entre as pessoas e a circulação de ar não é satisfatória como é o caso do ambiente escolar. Especialistas da área da saúde recomendam o uso da máscara facial de proteção como forma de controlar a disseminação desse vírus. No Brasil em particular, com o retorno das aulas no formato presencial surge uma nova preocupação com relação ao uso de máscara de proteção por parte da comunidade escolar principalmente na rede pública de educação, onde os espaços de uso coletivo não são amplos e diversos indivíduos resistem ao uso dessa proteção individual. Diante disso, deu-se início ao estudo de um modelo computacional usando Deep Learning chamado YOLO, para detectar por meio das imagens das câmeras de vigilância as pessoas no ambiente escolar que não estão usando máscara. Na fase de testes desse estudo, dentre todas as classificações, indivíduos com máscara e sem máscara, que o modelo fez 100% estavam corretas.
A Semantic Model to Assist Policy Refinement Mechanisms for NFV-MANO Systems
Authors: Bonfim Michel , Freitas Fred , Fernandes Stenio
Published: July 2021

Management in NFV scenarios is a complex task. In this scenario, automated policy refinement can be used to enforce NFV-MANO functions to deal with the increased complexity. However, existing solutions do not perform policy analysis. Therefore, in this work, we propose a semantic model in OWL 2, named Onto-Planner, to assist the policy refinement process for NFV-MANO systems. Preliminary results show that Onto-Planner provides policy analysis when a DL reasoner is applied.
Identificação e Classificação do relevo do município de São Martinho da Serra – RS
Authors: Dotto Antonio Von Ende , Robaina Luís Eduardo de Souza
Published: July 2021

The relief is one of the main definers of the environmental units, so that its compartmentalization is closely related to the distribution of the other attributes of landscape genesis. The objective of this study is to establish a division of the relief of the municipality of São Martinho da Serra, Rio Grande do Sul. Cartographic bases in digital format associated with the Geographic Information System were used, through automated methods and with the integration of morphometric variables. For the definition of the relief forms, the combined analysis of the morphometric attributes amplitude and slope was considered, identifying flat areas, gentle hills of altitude, rolling hills, association of hills with large hills and buttes and isolated buttes. The relief elements were obtained through the automatic technique that consists of the analysis of the gray level of a central cell and its neighbors, determining topographic differences. The identified elements are flat, peak, ridge, shoulder, spur, slope, hollow, footslope, valley and pit. For the classification of the forms of the slopes, the profile and plane of curvature of the slopes were used, defining 4 geomorphometric units defined as Unit I convex-convergent, Unit II concave-convergent, Unit III convex-divergent and Unit IV concave-divergent. In general, the methodology used obtained satisfactory results, allowing a quick and consistent analysis of the relief of the municipality.
As Infecções Sexualmente Transmissíveis em livros didáticos de biologia do ensino médio: uma análise de conteúdo
Authors: Silva Halana Rafaela Alves da , Silva Thaís Soares da , Mesquita Gemilton De Freitas , Cavalcanti Isabella Macário Ferro
Published: July 2021

The aim of this study was to analyze the content of STIs in the didactic collections of Biology of 2018 recommended by the National High School Textbook Program (NHSTP) of the Ministry of Education. Eight didactic collections of biology of NHSTP were selected and analyzed. The methodology of the study was thematic content analysis, with the definition of five categories a priori: location of the theme; structure and formatting; content; language and visual resources that were divided into criteria and subcriteria. The other books evaluated did not address the subject to the satisfaction, being flawed/superficial, which shows that the theme STIs can still be better explored in some biology textbooks in high school. Therefore, it is still important to encourage teachers to explore the subject better with their students, going beyond textbooks. Thus, the study concluded that most of the high school books recommended by NHSTP do not address the theme STIs effectively, generating the need for complementary didactic planning by teachers in order to broaden the debate on this subject in the classroom.
Aesthetics and perception of mobile reality: Architectural prospective
Authors: Mako Vladimir
Published: July 2021

This article discusses a possibility that the notion of mobile reality, as theorised by a few important philosophers at the beginning of the twentieth century, and contemporary architectural ideas, could be complementary according to dynamic characteristics of aesthetic perception and experience. This, at first glance odd statement, could be justified by the relative similarity that philosophical and architectural ideas at the beginning of the twentieth and the twenty-first century expose through fundamental characteristics of their appearance. As a matter of fact, dynamic aesthetic sensations are the essential values of avant-garde understanding of architectural and urban design, and the notion of mobile reality is one of its fundaments. These ideas could be applied on diverse design approaches and dynamic aesthetic sensations of contemporary architecture.
Aesthetics of unspoken: Architectural form and visible boundary of language
Authors: Stevanović Vladimir , Raičević Andrea
Published: July 2021

Stonborough House is a house in the heart of the city of Vienna that was, apart from architect Paul Engelmann - a disciple of Adolf Loos, designed and constructed by philosopher Ludwig Wittgenstein, at the suggestion of his sister Margaret Stonborough-Wittgenstein. In an attempt to connect Wittgenstein's philosophy with his work as an architect, the Stonborough House has often been named 'a visible form of his teaching'. Therefore, this paper intends to point out that translation into a substitute language of architecture became a meaningful way of addressing philosophical issues, and that the credo of Wittgenstein's philosophical ethics, which was restraint from the redundant, found articulation of its aesthetic value through architectural rhetoric.
Will Marina Abramović die?
Authors: Racanović Svetlana
Published: July 2021

The gradual and then ecstatic acceleration and diversification of Marina Abramović's choices in life and art are the result of her commitment to install and introduce into her performance-machine the power of perpetual mobility. That final line of end/ ings of the horizon disappearing into Nothingness, the line of Death which she touched and invoked in her life and work on many occasions, is neither to be melancholically accepted, nor desperately tamed or fiercely denied. Abramović activates this line of the last horizon, turning it around so that it becomes vital rather than fatal, cyclic rather than liminal, (re)turning - aspace that gives birth to (hyper)productivity. There is a relentless striving to disturb, slow down, curb, disable the work of Time, to change the path of Time's arrow. She endeavours to reconstruct, revitalise, rejuvenate, to extend the duration of the body of her art, the body of performance art and, consequently, of her biological body. A number of methods and mechanisms are used for this purpose - starting from documentation, technical multiplication, substitution, extension and virtualisation and even spectacularisation of her body and the body of her art.
Architectural work of Aleksandar Deroko: Beauty of emotional creativity
Authors: Kuletin-Ćulafić Irena
Published: July 2021

This paper studies significant and forgotten, but not less important, built and unrealised designs by Serbian architect Aleksandar Deroko. It seeks to achieve a continuous view in dealing with Deroko`s architectural work versus the historical discontinuity of political, territorial-geographic and social circumstances. It is impossible to separate Deroko as an architect from Deroko as a scholar, researcher, historian of architecture and art, an academic professor, painter, artist, writer, chronicler of his time, protector, conservator and historiographer of Serbian cultural heritage. The main aim of this paper is to apply comprehensive research approach within which his work in the field of architectural design will be considered in a complementary and pluralistic way. Deroko's architectural projects examined in their details and altogether represent distillate of Deroko's erudite personality, which casts shadow on relevant questions of Serbian history of architecture placement: How to understand it, observe and examine it, from Yugoslav or Serbian perspective, from the position of continuity or discontinuity, through characteristics of general or particular?
Aleksandar Deroko: Rebuilding Smederevo after 5 June 1941 explosion
Authors: Mladenović Milorad
Published: July 2021

Aleksandar Deroko had a noteworthy and decisive impact on the architectural culture of Smederevo. This paper will not treat the issue of his exceptional work on evaluating and protecting the medieval Smederevo Fortress, but rather it will focus on a very specific period during which Deroko, as an architect, set up a significant number of parameters for a new vision for Smederevo's urban culture. This vision is embodied in his projects and architectural realisations in one of the most delicate periods of the town's history, during its reconstruction that lasted a few years after a horrific wartime explosion nearly wiped Smederevo off the map, on 5 June 1941. In spite of many different ideological and political reasons, a comprehensive historical and monographic assessment of Deroko's works in Smederevo had not been made to this date. This paper will assess subjects such as Deroko's relationship with the city's historical and cultural heritage, political and ethical qualities of this relationship during a delicate period in Serbian history, and architectural and aesthetic principles that affected the way Deroko would shape his work in Smederevo and his vision for a rebuilt city. Lastly, this paper will hint at the qualifications of his work in Smederevo and its impact on the present-day town.
Introduction of Vernacular Architecture studies at the Faculty of Architecture in Belgrade
Authors: Roter-Blagojević Mirjana , Nikolić Marko
Published: July 2021

The paper examines the work of Aleksandar Deroko at the University of Belgrade's Faculty of Architecture and the inclusion of his rich personal knowledge about the vernacular architecture in the study programme, which he gained from long-term field research. As an assistant professor, he introduced the interpretation of vernacular architecture in the course on Byzantine and Old Serbian Architecture in 1929. After the study programme reform in 1935, a new course - named Old Serbian Architecture - was established, with one semester dedicated to the medieval monumental architecture and the second to rural and urban houses. In 1945/46 academic year, the course was renamed Vernacular Architecture and it incorporated medieval and vernacular architecture of the former Yugoslavia. Practical assignments dealt more with vernacular architecture and, through them the student's discovered the fundamental principles and methods of the vernacular construction. The goal of the studies was for students to comprehend and adopt basic traditional canons of construction and apply them to their own projects of cooperative centers, countryside schools, monasteries, etc. Through illustrations the paper will present, till now unpublished, student projects from the archives of Belgrade's the Faculty of Architecture's office for the architectural heritage of Serbia.
Authorship and language in contemporary architects' books
Authors: Balık Lökçe
Published: July 2021

This paper examines theoretical, graphical, and material dimensions of the contemporary print culture of architecture with a focus on one work from a variety of European practices. It regards the contemporary architect's book as a speculative and discursive design object. Michel Foucault, particularly in his works, What is an Author? (1969) and The Archaeology of Knowledge (1972), criticises that while constructing an author's body of works, alternative and unclassified genres are omitted from the domain and the texts attached to the single name belong to a system of homogeneity, filiation, and reciprocal explanation. Yet the contemporary architect's book expands the borders of genres by comprising unconventional materials, such as musical notes, artistic photographs, paintings, technical and scientific diagrams, official reports, building regulations, newspaper articles, and advertisements, as well as combining texts and photographs from co-workers, partners, clients, and users, rather than emerging as the product of a single author. The paper interprets the use of various forms of graphical narration and the coalescence of novel terminology and jargon as a contribution to the power of language and discursive formation.
Visceral adiposity syndrome and cardiometabolism
Authors: Lopes Heno , Egan Brent
Published: July 2021

The distribution of fat in the human body is related to hemodynamic and metabolic homeostasis. Brown fat is inversely related to body mass index and is associated with a lower probability of developing diabetes. Beige adipose tissue shares some functional characteristics with brown adipose tissue. White adipose tissue constitutes the majority of the fatty tissue and is mainly distributed in the subcutaneous and abdominal cavity. Intra-abdominal white fat has gained prominence in recent years for its association with cardiovascular risk factors and higher cardiovascular mortality. This review article discusses the human adaptation in the environment, a sympathovagal and hypothalamic-pituitary-adrenal imbalance as a possible cause of increased visceral adiposity and its consequences on cardiometabolism.
The managerial implications of the labor market and workplace shortage in Central Eastern Europe
Authors: Poór József , Slavić Agneš , Nikolić Milan , Berber Nemanja
Published: July 2021

In the recent years the labor market of the Central and Eastern European (CEE) countries has changed a lot. One of the main business challenges in the CEE region is the worker shortage. The possible reasons of this phenomenon are the emigration of the labor force from the countries of the former Eastern Bloc to the Western countries, the negative demographic tendencies in the region, the effects of economic crisis and the significant wage differences in the countries of European Union. This paper presents the first results of an international research conducted in six countries from the CEE region (Austria, Czech Republic, Hungary, Romania, Serbia and Slovakia) on the reasons and managerial implications of the current labor force shortage. The research questionnaire was filled out in 797 companies and institutions in the CEE region. In our paper we will show the size, ownership and the sectoral distribution of our sample, as well as the average turnover rate, the average time to fill a position in, the positions hard to fill in, the possible reasons of labor shortage and the successful organizational and governmental programs to deal with labor market shortage. The obtained results may be a useful input for the formulation of human resource management programs in the organizations facing with labor market shortage in Serbia and other CEE countries.
Research into unplanned purchases on the Serbian market
Authors: Đukić Suzana , Stanković Jelena
Published: July 2021

Purchases of products and services are mainly the result of planned actions of consumers based on identified needs and desires. However, impulse purchases that consumers did not plan before entering the store are quite common as well. Such purchases are stimulated by the consumers' sudden needs, current mood, recommendations of the seller and/or other consumers, as well as in-store incentives such as: the atmosphere in the sales facility, discounted prices, gifts. Also, numerous innovations make impulse buying easier for consumers, like: flexible working hours of shops, affordable supply of products/services, online sales, offer of so-called "instant" loans, the existence of ATMs. Unplanned purchases are not exclusively a consequence of the impulse-driven reaction of consumers. In addition to pure impulsiveness, there are other types of unplanned purchases, such as: suggestion effect, planned impulsivity, reminder impulse buying effect, and planned purchase of a certain type, but not brand of product. The aim of this paper is to point out the importance and basic characteristics of unplanned purchases, as well as the factors that influence consumer behavior while making such purchases. Conducted empirical research enabled the identification of the most important motives of unplanned purchases made by consumers in the Republic of Serbia, their frequency in buying different product categories, the connection of different shopping situations with unplanned purchases, as well as the determination of differences between certain demographic and economic groups of consumers in making such purchases. The research results and their analysis enabled the formulation of guidelines for the development of marketing strategies of companies from the Republic of Serbia as a model of response to this type of consumer behavior.
Delitos de odio y redes sociales: el derecho frente al reto de las nuevas tecnologías
Authors: Marabel Matos Jacinto Jesús
Published: July 2021

Durante la última década hemos asistido al incremento y preeminencia de las redes sociales. Facebook, Twitter, Instagram o Snapchat han cambiado la manera en la que nos relacionamos, multiplicando y viralizando los efectos de nuestras manifestaciones hasta límites insospechados. También de las expresiones que buscan incitar al odio y a la violencia respecto a ciertos colectivos discriminados. En este sentido, todos los registros oficiales apuntan hacia una preocupante proliferación de contenidos violentos delictuales en redes sociales, que se ve facilitada por las dificultades que entraña la aplicación del art. 510.3 del Código Penal frente al derecho de libertad de expresión garantizado en el art. 20.1 de la Constitución Española. Entre las propuestas que abogan por la especialización en la persecución del ciberodio, los sistemas de filtrado o la autorregulación de las conductas, sin duda el Derecho está llamado a protagonizar un papel fundamental ante uno de los principales retos de la Era de las Nuevas Tecnologías.

El ancestral castigo del siglo XXI
Authors: Marqués Suárez José Emilio
Published: July 2021

Este trabajo hace un repaso en la evolución de las penas privativas de libertad y muestra su progreso a lo largo del tiempo. Observaremos en él los cambios sociales que pudieron haber influido en la concepción y desarrollo de estas, valorando a su vez si los mismos, de haberse producido, han hecho que la sociedad actual haya desechado la misma como pena prioritaria destinada al castigo de las personas tras el quebrantamiento de las normas impuestas por el legislador, dada la aparición de nuevas formas de control social. Interesa igualmente saber si estas innovaciones en materia de observación y vigilancia, tecnológicas en su mayoría, acompañan el devenir de las condenas o, por el contrario, la sociedad en general y el legislador en particular obvia este tipo de sistemas continuando con medidas de castigo más propias de los ancestrales métodos de control que del actual y moderno siglo XXI. Es una preocupación, la de la concepción de los cambios sociales en materia de “castigo” que interesa en aras de saber, no sólo en qué paradigma se desenvuelve nuestro sistema penitenciario español actual, sino en qué aspectos ha cambiado la esencia penológica desde el punto de vista social.

La secuela se trata de una obra que, de la misma forma que ocurre con otras obras derivadas, no tiene una regulación específica en nuestra legislación de propiedad intelectual. Esto ocurre a pesar de que no es una figura de creación reciente. La secuela se ha manifestado en diferentes medios, dependiendo del momento histórico. En un principio, su aparición se produjo en la literatura y más tarde en el medio audiovisual y cinematográfico. Existen determinados criterios que servirán para distinguirla de la obra originaria de la que ha surgido, así como de otras obras derivadas, en función de su grado de originalidad.

Épocas e densidades de semeadura sobre o desempenho agronômico do arroz irrigado no sistema pré-germinado
Authors: Martins Júnior Marcos Cardoso , Sangoi Luís , Kuneski Hugo François , Stinghen Jussara Cristina , Leolato Lucieli Santini , Turek Thais de Lemos , Oliveira Vander de Liz
Published: July 2021

Nos últimos anos, os produtores de arroz irrigado do Litoral Sul de Santa Catarina têm antecipado a semeadura da cultura para o início do mês de setembro, visando viabilizar o cultivo do rebrote. Paralelamente a isto, eles têm aumentado a densidade de semeadura para compensar o menor crescimento da cultura. Este trabalho foi conduzido com o objetivo de analisar os efeitos da época e densidade de semeadura sobre o desempenho agronômico do arroz no sistema pré-germinado. O experimento foi implantado no município de Praia Grande, SC, na safra 2018/2019. O trabalho foi conduzido no delineamento experimental de blocos ao acaso, arranjados em parcelas subdivididas. Na parcela principal testaram-se três épocas de semeadura: 10/09 (semeadura antecipada), 15/10 (semeadura preferencial) e 20/11 (semeadura tardia). Nas subparcelas avaliaram-se quatro densidades de semeadura: 80, 120, 160 e 200 kg de sementes ha-1. Foram avaliados caracteres morfológicos, o rendimento de grãos e seus componentes. O rendimento de grãos variou de 6.277 a 9.605 kg ha-1 e foi afetado pela interação entre época e densidade de semeadura. A máxima produtividade foi obtida com a semeadura feita na época preferencial, com densidade de 120 kg ha-1. Na semeadura antecipada, o rendimento aumentou linearmente 12,54 kg ha-1 para cada kg de sementes adicionado à menor densidade. A máxima produtividade obtida nesta época de semeadura foi de 7.858 kg ha-1 com 200 kg  ha-1 de sementes. A densidade de semeadura teve pouco impacto sobre a produtividade na semeadura tardia. Nesta época de semeadura, o maior rendimento (8.546 kg ha-1) foi registrado na densidade de 120 kg ha-1. A densidade ótima para maximizar a produtividade do arroz pré-germinado no Litoral Sul de Santa Catarina depende da época de semeadura, sendo mais alta quando a cultura é semeada antecipadamente.
Cotton aphid feeding preference and the development of watermelon plants treated with silicon
Authors: Pereira Rosane Rodrigues da Costa , Leite Mara Pestana , Silva Douglas Marcelo Pinheiro da , Zaché Ronelza Rodrigues da Costa , Pereira Carlos Eduardo
Published: July 2021

The cotton aphid is one of the main watermelon crop pests and may cause a reduction in productivity due to the suction of sap, the transmission of viruses, and decreased photosynthetic capacity. The objective of this research was to evaluate the feeding preference of the aphid Aphis gossypii and the biometric aspects of watermelon cultivar plants submitted to silicon application. The experiment was conducted at the Institute of Education, Agriculture, and Environment of the Federal University of Amazonas, in Humaitá, Brazil. A randomized complete block design was used for testing preference with choice and a completely randomized design to study the biometric parameters of the plants. The treatments were distributed in a 2 x 3 factorial scheme (with and without silicon and considering cultivars Crimson Sweet, Fairfax, and Charleston). Silicic acid was applied at a 1% concentration directly on the substrate around the plants (equivalent to 1 t SiO2 ha-1), 25 days after sowing. The aphids in the breeding were kept in cucumber plants of cultivar Caipira. The treatments were evaluated through the preference test on watermelon cultivars and biometric studies of plant growth and development. The data were submitted to an analysis of variance, and the means were compared using the F and Scott-Knott tests at the 5% probability level. Silicon does not affect the preference of Aphis gossypii in different watermelon cultivars and negatively affects plant growth and development.

Published: July 2021

Actualmente, la familia se encuentra ante retos que requieren de su eficiencia y eficacia en la crianza, protección y orientación de los hijos, es decir, la parentalidad y la capacidad de los padres de ejercerla de forma competente. Desde este punto de vista, destaca la necesidad de un modelo educativo centrado en el desarrollo de las competencias parentales que proporcione conocimientos, habilidades y actitudes que optimicen el rol parental respecto al desarrollo pleno y sistémico del ser humano. Ante la necesidad de conocer si los padres asumen de forma óptima su papel en la educación de sus hijos, se plantea como objetivo principal de este artículo el diseño de un instrumento para el análisis de la competencia parental en las etapas de Educación Infantil y Primaria. Para responder a este objetivo realizamos un análisis de la literatura científica y revisamos los principales instrumentos de evaluación, nacionales e internacionales, referidos a este campo objeto de estudio. Posteriormente, procedimos al diseño y validación de contenido y constructo del instrumento a través de comités de expertos y al análisis de fiabilidad factorial exploratorio y confirmatorio. Los resultados obtenidos evidencian que se trata de una herramienta con adecuada validez, discriminante y convergente, para la población objeto de estudio; sin embargo, se observa una baja fiabilidad para algunos de los factores/dimensiones.

Currently, families are faced with continuous challenges that require efficiency and effectiveness in the process of upbringing and a conscious awareness of parenthood and how to implement it based on protecting and orienting children. From this point of view, the need for an educational model focused on the development of parental competences, that is, on providing knowledge, skills and attitudes that optimize parental roles with respect to the full and systemic development of human beings becomes evident. Given the need for parents to exercise their role in the education of their children, the main objective of this article is the design of an ad hoc instrument for the analysis of parental competence in Infant and Primary Education. In order to respond to this objective, we conducted an analysis of the scientific literature and reviewed some of the existing national and international evaluation instruments related to this field. In addition, we designed an instrument and undertook a study of content and construct validation through expert committees and an exploratory and confirmatory factorial reliability analysis. Results evidence that this is a test that presents an adequate discriminant and convergent validity for the population under study but a low reliability for some of the factors/dimensions.
Enseñar historia en las escuelas públicas del siglo XXI. ¿Qué historia enseñar y para qué?
Authors: García Fernández Gonzalo Andrés
Published: July 2021

En el presente artículo tenemos como principal objetivo discutir, grosso modo, acerca de los principales debates en torno a la enseñanza de la Historia en el ámbito escolar en el siglo XXI. Si bien existe un intenso debate al respecto, también existen consensos, y nuestra labor será identificar qué preguntas han hallado respuesta, cuáles aún no y en qué ámbitos. También nos adentraremos en un análisis sobre cuáles son los objetivos de dichos debates, consensos y preguntas: si estas se enfrentan más a la forma o al fondo de la enseñanza escolar de la Historia.
Sincretismo apuleyano-lucianesco para un cambio de paradigma hacia la novela moderna (con calas en el pensamiento estético de Cervantes y Quevedo)
Authors: Escobar Borrego Francisco Javier
Published: July 2021

El presente artículo ofrece un análisis circunscrito a la recepción de El Asno de oro en la narrativa española áurea con énfasis en el sincretismo apuleyano-lucianesco como cambio de paradigma hacia la novela moderna. Atendiendo a esta pervivencia de notoria influencia en el humanismo europeo, destacados autores españoles de la prosa de ficción de mediados del siglo XVI trazaron renovados caminos de experimentación estética que van a preludiar la originalidad del pensamiento narrativo de Cervantes y Quevedo. Especial relieve adquiere, por último, la difusión que tuvo la edición de El Asno de oro impresa en Medina del Campo en 1543, no solo a mediados del siglo XVI sino también en época contemporánea gracias a su inclusión en los Orígenes de la novela por Marcelino Menéndez Pelayo, contribuyendo así a la vigencia y recepción crítica de este clásico universal hasta nuestros días.
Variedad en la unidad: la «novella» italiana en la construcción de «El Abencerraje» (I)
Authors: Resta Ilaria
Published: July 2021

Este estudio representa la primera parte de un trabajo más amplio en el que pretendemos profundizar en la influencia de la novella italiana en El Abencerraje, texto que abre camino para la difusión y circulación del género morisco. En particular, en este artículo aclararemos ante todo algunas cuestiones inherentes a un hipotético vínculo temático entre la historia de El Abencerraje y la novella 49 de la colección de Masuccio Salernitano, respaldado por una parte de la crítica anterior. Un vínculo que, según probaremos con datos textuales, no se sostiene. Nos centraremos, además, en la construcción novellistica de la historia del moro y el cristiano, apuntando a sus características compositivas. Finalmente, en la última parte del trabajo trataremos sobre la distinta funcionalidad que El Abencerraje va adquiriendo en las tres diferentes versiones que nos han llegado, apuntando también a su integración en cuerpos narrativos más extensos y genéricamente diferentes.
OPTIMIZACIJA STRUKTURE KAPITALA U FUNKCIJI POBOLJŠANJA FINANSIJSKOG POLOŽAJA NA PRIMJERU PREDUZEĆA "ELEKTROKRAJINA" AD BANJA LUKA
Authors: Janjić Dragan
Published: July 2021

U nekim fazama razvoja kod kompanija se vrlo često pojavljuje potreba da se privuku spoljni izvori finansiranja. Jedno od osnovnih pitanja koje se postavlja jeste: koji je optimalan odnos duga i akcijskog kapitala u finansiranju kompanije, odnosno kako se određuje optimalna struktura kapitala neke kompanije? Dakle, ovdje je riječ o strukturiranju pasive bilansa stanja preduzeća, odnosno o uspostavljanju optimalnog odnosa sopstvenog kapitala i dugova (obaveza).Shodno tome, u cilju poboljšanja finansijskog položaja kompanija u Republici Srpskoj, u okviru ovog rada pokazaćemo kako se vrši optimizacija kapitala. Takođe, kroz ovaj rad ćemo pokazati važnost optimizacije strukture kapitala u cilju uspostavljanja dugoročne finansijske ravnoteže. Prema tome, sigurni smo da će tvrdnje, činjenice i dokazi prikazani u ovom radu biti od koristi kako studentima, tako i akademskim istraživačima, teoretičarima i investitorima.
UTICAJ DIGITALIZACIJE NA POSLOVANJE ORGANIZACIJA I ODABIR POSLOVNE STRATEGIJE: ELEKTRONSKA TRGOVINA KAO VID POSLOVNE STRATEGIJE PREDUZEĆA U BOSNI I HERCEGOVINI (BiH)
Authors: Dragišić Slavica
Published: July 2021

Digitalna tehnologija je uticala na organizacije da mijenjaju i prilagođavaju poslovnu strategiju novim uslovima poslovanja na način da digitalizaciju postave u fokus svog poslovanja, a elektronsku trgovinu definišu kao poslovnu strategiju koja doprinosi unapređenju poslovanja i jačanju konkurentnosti. U ovom radu nastoji se pronaći odgovor na pitanje u kojoj mjeri organizacije idu ka digitalizaciji poslovanja i da li je elektronska trgovina efikasna poslovna strategija za preduzeća u Bosni i Hercegovini (BiH)? Cilj istraživanja je da utvrdimo da li digitalizacija i elektronska trgovina utiču na izmjene u načinu poslovanja organizacija u BiH. U širem smislu, analizom prikupljenih podataka i njihovim deskriptivnim prikazom, rezultati istraživanja ukazuju na pozitivnu vezu između primjene savremene informacione tehnologije i digitalizacije na poslovanja organizacija, te primjenu elektronske trgovine kao oblika poslovne strategije. Rezultati istraživanja mogu biti korišteni u smislu unapređenja elektronske trgovine i potpuniju digitalizaciju poslovanja.
GluA4 facilitates cerebellar expansion coding and enables associative memory formation

Published: July 2021

AMPA receptors (AMPARs) mediate excitatory neurotransmission in the central nervous system (CNS) and their subunit composition determines synaptic efficacy. Whereas AMPAR subunits GluA1–GluA3 have been linked to particular forms of synaptic plasticity and learning, the functional role of GluA4 remains elusive. Here, we demonstrate a crucial function of GluA4 for synaptic excitation and associative memory formation in the cerebellum. Notably, GluA4-knockout mice had ~80% reduced mossy fiber to granule cell synaptic transmission. The fidelity of granule cell spike output was markedly decreased despite attenuated tonic inhibition and increased NMDA receptor-mediated transmission. Computational network modeling incorporating these changes revealed that deletion of GluA4 impairs granule cell expansion coding, which is important for pattern separation and associative learning. On a behavioral level, while locomotor coordination was generally spared, GluA4-knockout mice failed to form associative memories during delay eyeblink conditioning. These results demonstrate an essential role for GluA4-containing AMPARs in cerebellar information processing and associative learning.
Quantifying the effects of delisting wolves after the first state began lethal management
Authors: Treves Adrian , Santiago-Ávila Francisco J. , Putrevu Karann
Published: July 2021

Predators and their protection are controversial worldwide. Gray wolves, Canis lupus, lost U.S. federal protection (delisting) and the State of Wisconsin began lethal management first among all states and tribes that regained authority over wolves. Here we evaluated the initial success of reaching the state’s explicit objective, “…to allow for a sustainable harvest that neither increases nor decreases the state’s wolf population…” We used official state figures for hunter-killed wolves, population estimates from April 2017–2020, and the latest peer-reviewed model of individual wolf survival to estimate additional deaths resulting from federal delisting. More than half of the additional deaths were predicted to be cryptic poaching under the assumption that this period resembled past periods of liberalized wolf-killing in Wisconsin. We used a precautionary approach to construct three conservative scenarios to predict the current status of this wolf population and a minimum estimate of population decline since April 2020. From our scenarios that vary in growth rates and additional mortality estimates, we expect a maximum of 695–751 wolves to be alive in Wisconsin by 15 April 2021, a minimum 27–33% decline in the preceding 12 months. This contradicts the state expectation of no change in the population size. We draw a conclusion about the adequacy of regulatory mechanisms under state control of wolves and discuss the particular governance conditions met in Wisconsin. We recommend greater rigor and independent review of the science used by agencies to plan wolf hunting quotas and methods. We recommend clearer division of duties between state wildlife agencies, legislatures, and courts. We recommend federal governments reconsider the practice of sudden deregulation of wolf management and instead recommend they consider protecting predators as non-game or transition more slowly to subnational authority, to avoid the need for emergency relisting.

Consulta indígena de concesiones mineras. Comentario de jurisprudencia
Authors:   Pontificia Universidad Católica de Chile, Salmona Maureira Francisco José
Published: July 2021

En este trabajo se analiza la pertinencia de la consulta indígena en el procedimiento concesional minero. El interés por el tema surge a partir de jurisprudencia de los Tribunales de Justicia. Nuestra tesis es que las concesiones mineras son actos administrativos y, en consecuencia, podrían requerir de una consulta indígena previa a su dictación, en la medida que impliquen una afectación de los pueblos indígenas interesados. Con todo, no es posible la consulta en el actual régimen de procedimiento concesional.

Este artículo analiza el modelo de normas en el mercado de compra pública colombiano en el marco de la creación de los documentos tipo. La tesis del trabajo es que la implementación de los documentos tipo depende de un modelo de reglas sólido. Para ello, se explican las características de los modelos normas: reglas y principios. Luego se exponen las razones por las cuales, en ciertos contextos, se justifica el modelo de reglas. Por último, se explica que, en el diseño institucional para la implementación de los documentos, subyace un sistema de instrucciones que está vinculado a la configuración del modelo de reglas.
