La Educación de Personas Adultas a los Cincuenta Años de la Ley General de Educación.
Authors: Medina Fernández Óscar
Published: February 2021

Using as a reference the 1970 General Education Act, as well as other earlier and later education laws, I address the evolution of adult education from the 19th century to the present day, exploring three great challenges essential for the implementation of a credible and viable educational policy: a) Specific educational offer versus compensatory and substitute character; b) Differentiated pedagogy versus school model; and c) Legislation on the educational universe versus formal and official educational system. This analysis, in which legislation is contrasted with educational achievements and with the theories of authors, leads us to conclude that, throughout more than two centuries of existence, in Spain there has been no educational policy whatsoever in the area of adult education. There are several reasons for this fact: because the growth that this educational sector has experienced is unknown, and the personal, cultural, economic, social, and political benefits of this reality are not known; because the laws have been limited to the regulation of the formal and official educational system, leaving out a good part of the education that adults have and carry out; and because the pedagogical concept that justifies it has not transcended society or the competent institutions in the field
Teatro y educación en la Ley General de 1970. Avances y retrocesos.
Authors: Vieites Manuel F.
Published: February 2021

The General Education Act, enacted in 1970, appears as the first attempt to regulate Theatre Education in Spain, considering all its diversity. On the one hand, this new law places Art Education in the General Education curriculum and provides it an expressive approach. This showed the pedagogical potential of different procedures of dramatic and theatrical nature, confirmed its educational legitimacy, and produced developments in both their empirical and scientific cultures. On the other hand, the Act stated and promoted the integration of Schools of Dramatic Art and its courses in the university, in tune with what had been its status since 1857 with the Moyano Education Act, and with similar transitions taking place in Europe in the same direction. This paper, which has been written after an analysis of the educational norms derived from the application of the Act, combined with a review of the literature generated at that period, shows the advances the change enhanced. Also, reveals that later Educational Acts were not always confirmed or consolidated, and that provoked important setbacks causing persistent of problems. Also, further research lines particularly relevant in the development of the further research lines particularly relevant in the development of the History of Theatre Education and also of the History of Theatre Pedagogy in Spain have been provided.
La Alfabetización. Una competencia educativa para el mundo globalizado.
Authors: Vielma Rondón Joel Oswaldo
Published: February 2021

This article seeks to reflect on the implications of literacy as a fundamental educational competence for citizens of the globalized world. In order to achieve this purpose, we characterize some of the paths on which this knowledge is disseminated and explain how it relates to written culture, educational processes and Information and Communication Technologies (ICT). In addition, it opens a space for reflection on the matter in Venezuela in recent years; supported by Bravo (2011) and Uzcátegui and Bravo (2017) reviews of official data. It is emphasized that literacy is decisively linked to the construction of the personal autonomy necessary for lifelong learning and the consideration of reading and writing as social and cultural practices. In conclusion, it is considered that all entities and social actors should assume the commitment to literacy and the promotion of written culture, in its different formats and modalities. In this case, democratic governments’ responsibility of implementing cultural, educational, social and economic policies is underlined, for their implementation increases responsibility towards the people, and also, towards their living conditions.
Maximizing Sequence-Submodular Functions and Its Application to Online Advertising
Authors: Alaei Saeed , Makhdoumi Ali , Malekian Azarakhsh
Published: February 2021

Motivated by applications in online advertising, we consider a class of maximization problems where the objective is a function of the sequence of actions and the running duration of each action. For these problems, we introduce the concepts of sequence-submodularity and sequence-monotonicity, which extend the notions of submodularity and monotonicity from functions defined over sets to functions defined over sequences. We establish that if the objective function is sequence-submodular and sequence-nondecreasing, then there exists a greedy algorithm that achieves [Formula: see text] of the optimal solution. We apply our algorithm and analysis to two applications in online advertising: online ad allocation and query rewriting. We first show that both problems can be formulated as maximizing nondecreasing sequence-submodular functions. We then apply our framework to these two problems, leading to simple greedy approaches with guaranteed performances. In particular, for the online ad allocation problem, the performance of our algorithm is [Formula: see text], which matches the best known existing performance, and for the query rewriting problem, the performance of our algorithm is [Formula: see text], which improves on the best known existing performance in the literature.

En este artículo de pensamiento comparto lo que me ha permitido pensar mi trayectoria como docente e investigadora el ámbito de las tecnologías educativas.  Comienzo el texto desde mis contactos iniciales con Brasil. Sigo con una primera aproximación al tema que me permite fundamentar mi posicionamiento frente a “las tecnologías”, que sitúo en la denominada teoría crítica. Continúa explicitando el comienzo de mi colaboración con las universidades brasileñas y acaba con un acercamiento explícito a un contexto bastante desconocido para mí como la Amazonia, inevitablemente afectado por las tecnologías digitales -además de otras muchas, compartiendo un sistema de trabajo que a mí me gustaría poner en marcha en mi contexto, con la finalidad de poder tener algo que decir en el tipo de sociedad en la que quisiera vivir. Para que no sigan siempre haciéndolo “otros”.
ECOS DE UM CORPO (DES)VIADO
Authors: Nunes da Silva Nadson Fernando , De Brito Maria Dos Remedios
Published: February 2021

Resumo: A escrita compõe-se sobre as marcas vivas do corpo, buscando as linhas de fuga para pensar a educação e a sexualidade em seu percurso experimental, sendo o mesmo fio condutor metodológico que infiltra as paredes educacionais por uma nova imagem de corpo-professor, apontando para a ideia de que os vazamentos ocasionados agem nas experimentações corporais que deslocam o corpo-masculino dos lugares convencionais e o aproximam do corpo-devir-viado. Esse processo se localiza dentro da minha experiência como professor de ciências, trazendo o corpo como ação inventiva, que se desloca para reconfigurar olhar e adentrar a estética da sensibilidade por uma educação-movediça, (re) criando novas conexões para afirmar o lugar do corpo-professor, viado, amazônico, incorporando modos de (r)existência.
MÁQUINA DE GUERRA E INFÂNCIA “ENTRE”: NOTAS SOBRE A DESTERRITORIALIZAÇÃO DA INFÂNCIA CONTEMPORÂNEA
Authors: Almeida e Silva Sampaio Helena
Published: February 2021

Este artigo parte de uma perspectiva sobre infância e criança pautada em Deleuze e Guattari e utiliza o conceito de “máquina de guerra” como uma forma de pensar a criação de novos espaços-tempos para suscitar acontecimentos e desterritorializar a infância contemporânea. Busca-se aqui, então, traçar uma linha “entre” os pontos fixos, numa tentativa de irromper a realidade e abrir espaço nas afirmações, prescrições e avaliações que “desabam” sobre as crianças, não apenas incluídas no ideal hegemônico de infância, mas governadas por dispositivos de subjetivação de um “Homo oeconomicus”. Para inventar outros mundos educativos possíveis, num contexto contemporâneo e neoliberal, requer-se a possibilidade de se pensar uma infância “entre”, de modo a tirar a criança da dicotomia incluída/excluída da infância.
RACHAR E DESPENCAR O CORPO-TERRITÓRIO
Authors: OLIVEIRA MIRANDA EDUARDO
Published: February 2021

O presente texto tem a sua tessitura a partir de provocações sobre a constituição do corpo-território (MIRANDA, 2014; 2019) do autor e como o ato de pesquisar tem sido uma das ramificações das colonialidades dentro da universidade. Para tal, inicia-se o texto com as provocações sobre as potências, imanências, lacunas e possibilidades do corpo no campo social e da educação. Nesse cenário, o autor mescla uma narrativa da sua experiência no transito pelo doutorado e a descoberta do dispositivo metodológico denominado de Sociopoética (GAUTHIER, 2014), a qual se estrutura em cinco princípios e exige um fazer ciência de corpo todo. Portanto, o autor deste texto sentiu a necessidade de ser atravessado pela Sociopoética e participou de um PERCURSO. Em seguida traz uma proposição decolonial batizada de Encruzilhada do Desenho Singular.
A EMPATIA NA PRODUÇÃO DE MATERIAIS DIDÁTICOS: REFLEXÕES SOBRE ARTEFATOS BILÍNGUES
Authors: Pimentel Claudia , Limite Keissy Sibelly Morais
Published: February 2021

O objetivo desse artigo é refletir sobre a produção de materiais didáticos para a educação infantil de surdos. A metodologia proposta se baseia na análise de materiais construídos por professoras, procurando perceber como e se favorecem a ampliação de sentidos, na medida em que dialogam com contextos mais amplos, como livros, cantigas e narrativas. A perspectiva teórica contempla a concepção de linguagem bakhtiniana, que entende que a enunciação organiza o pensamento. A organização estética dos materiais revela princípios éticos e epistemológicos. Percebemos que a produção de artefatos junto com as crianças, de maneira empática, produziu efeitos significativos no relacionamento interpessoal, aprimorou a comunicação e colaborou para aprendizagens significativas.
Aerosol-generating procedures in home care
Authors: Payne Drew , Peache Martin
Published: February 2021

COVID-19 has changed the landscape of healthcare in the UK since the first confirmed case in January 2020. Most of the resources have been directed towards reducing transmission in the hospital and clinical environment, but little is known about what community nurses can do to reduce the risk when they nurse people in their own homes? This article looks at what COVID-19 is, how it is spread and how health professionals are at an increased risk from aerosol-generating procedures (AGPs). There is also a discussion on the benefit of mask usage. It defines what AGPs are, which clinical procedures are AGPs, including ones performed in the community setting, and which identified clinical practices that have been mistaken for AGPs. There is also a discussion on the suitability of performing cardiopulmonary resuscitation (CPR). It also describes how to reduce the risk by the use of full personal protective equipment (PPE) and other strategies when AGPs are performed in a patient's home. It ends with general advice about managing the risk of COVID-19 transmission with patients in their homes.

Is mental ill health an aspect of ‘neurodiversity’? If so, is it ok to be neurodiverse within the context of mental health and how should those who are ‘neurotypical’ respond? Are people comfortable with the ‘labels’ of, and language and social constructs associated with, being neurodiverse and neurotypical as applied to mental health? These are the central questions that will be explored in this article through the lens of disability models.

Published: February 2021

This research aimed to analyze the levels of agreement between kindergarten teachers and principals in identifying the assessment of teachers’ teaching competencies and performance. The study was designed under a quantitative approach using a survey. It implemented a non-probability sampling technique with purposive sampling. The sample of the population comprised of 173 kindergarten teachers and 101 principals in Semarang District, Indonesia, or a total of 274 respondents. The data were collected through a questionnaire and analyzed using Cohen’s Kappa coefficient to measure the levels of agreement between raters and Pearson Chi-Square test was also utilized to determine the differences in perceptions among principals and teachers. The findings showed that the levels of agreement between raters were averagely in the no agreement category, implying the existence of differences in perceptions among teachers and principals. The involvement of a multi-rater strategy in such research is a rare effort, especially for the Early Childhood Education (ECE) level in Indonesia. Researches regarding teaching competencies and performance generally only involve single rater, either teachers or principals who judge themselves on their competencies and performance, thus the results tend to be subjective. In conclusion, the assessment of teaching competencies with the relation of cognitive abilities was conducted through a test that considered subjective questions and case analysis to evaluate the teachers’ skills based on their performance and self-description. Both personal and social assessments utilized self-assessment forms or autobiographies, which were completed with specific themes. Meanwhile, the performance assessment was observed with the assessment rubric and comparison with the learning process performed by an individual educator.
Karamardian Matrices: An Analogue of Q-Matrices
Authors: Sivakumar K.C. , Parameswaran Sushmitha , Wendler Megan
Published: February 2021

A real square matrix $A$ is called a $Q$-matrix if the linear complementarity problem LCP$(A,q)$ has a solution for all $q \in \mathbb{R}^n$. This means that for every vector $q$ there exists a vector $x$ such that $x \geq 0, y=Ax+q\geq 0$, and $x^Ty=0$. A well-known result of Karamardian states that if the problems LCP$(A,0)$ and LCP$(A,d)$ for some $d\in \mathbb{R}^n, d >0$ have only the zero solution, then $A$ is a $Q$-matrix. Upon relaxing the requirement on the vectors $d$ and $y$ so that the vector $y$ belongs to the translation of the nonnegative orthant by the null space of $A^T$, $d$ belongs to its interior, and imposing the additional condition on the solution vector $x$ to be in the intersection of the range space of $A$ with the nonnegative orthant, in the two problems as above, the authors introduce a new class of matrices called Karamardian matrices, wherein these two modified problems have only zero as a solution. In this article, a systematic treatment of these matrices is undertaken. Among other things, it is shown how Karamardian matrices have properties that are analogous to those of $Q$-matrices. A subclass of a recently introduced notion of $P_{\#}$-matrices is shown to possess the Karamardian property, and for this reason we undertake a thorough study of $P_{\#}$-matrices and make some fundamental contributions.
On the little secondary Bruhat order
Authors: Fernandes Rosário , Da Cruz Henrique F. , Salomão Domingos
Published: February 2021

Let $R$ and $S$ be two sequences of positive integers in nonincreasing order having the same sum. We denote by ${\cal A}(R,S)$ the class of all $(0,1)$-matrices having row sum vector $R$ and column sum vector $S$. Brualdi and Deaett (More on the Bruhat order for $(0,1)$-matrices, Linear Algebra Appl., 421:219--232, 2007) suggested the study of the secondary Bruhat order on ${\cal A}(R,S)$ but with some constraints. In this paper, we study the cover relation and the minimal elements for this partial order relation, which we call the little secondary Bruhat order, on certain classes ${\cal A}(R,S)$. Moreover, we show that this order is different from the Bruhat order and the secondary Bruhat order. We also study a variant of this order on certain classes of symmetric matrices of ${\cal A}(R,S)$.

It is proved that every matrix in $\mathrm{SL}_n(\mathbb{C})$ can be decomposed into a product of two commutators of unipotent matrices of index $2$. Moreover, two is the smallest such number.
Desmontando el determinismo biológico mediante el género
Authors: Castellanos Lorena
Published: February 2021

En el presente trabajo se aborda al género como un elemento fundamental en las desigualdades sanitarias entre hombres y mujeres tanto en el acceso y relación con los servicios de salud como en los resultados diferenciales referidos a tasas de morbilidad y mortalidad. Para tal efecto y a través de un análisis sociológico de la bibliografía más relevante en cuanto a la temática, se aborda en primer lugar la salud y sus determinantes mediante el estudio de investigaciones que relacionan desigualdades en salud con desigualdades sociales, es decir, las condiciones sociales en la determinación de la salud. En segundo lugar, se abordan algunas reflexiones de la teoría feminista en cuanto al género como categoría analítica cuyo eje central es la desnaturalización de las desigualdades sociales. En tercer lugar, se abordan los estudios sobre género y salud. Estos estudios relacionan la posición de las mujeres en la sociedad, su estado de salud y su utilización de las instituciones sanitarias. Por último, se mencionan algunas consecuencias del sesgo de género en salud. De esta forma se plantea al género como el concepto analítico que desmonta al determinismo biológico en su intento de naturalizar las desigualdades en salud entre hombres y mujeres, es decir, atribuirlas a supuestos hechos biológicos. Se concluye que el género permite entender que las desigualdades sanitarias entre hombres y mujeres no son producto de la biología, sino de un orden social que se expresa tanto en las instituciones sociales como en las prácticas individuales.

Published: February 2021

Objetivos. Aproximarse a los problemas específicos de las mujeres con trastorno de juego online desde la perspectiva de género. Material y Método. Estudio cualitativo realizado en 2019 mediante 10 grupos de discusión formados por pacientes en tratamiento y profesionales. Seis grupos fueron con pacientes mayores de edad en tratamiento por juego online. Se complementaron con una entrevista individual a una mujer en tratamiento. Cuatro fueron a profesionales (psicólogos/as y trabajadores/as sociales) con experiencia en el tratamiento del juego online. En total, se analizaron los discursos de 41 pacientes (3 mujeres y 38 hombres, con una edad media de 30 años) y 28 profesionales (20 mujeres y 8 hombres, con una media de 36 años). Resultados. Se presentan los resultados de los 12 nodos codificados en el conjunto de la investigación relativos a cuestiones de género, resumidos en 5: Masculinidad hegemónica; Jugadoras online: escasa presencia y visibilidad; Doble penalización, estigma y violencia; Mayor comorbilidad asociada a los mandatos de género: jugar para evadirse; Mujeres solas y dificultades para acceder a los recursos. Conclusiones. Durante el estudio se han confirmado hallazgos previos de la literatura que asimilaban la adicción a sustancias con el juego patológico online en las mujeres. Esta similitud se basa, entre otros, en los motivos que desencadenan la adicción, la mayor comorbilidad, el estigma y doble penalización, las intersecciones con las violencias de género, la soledad a la hora de afrontar los tratamientos y la invisibilidad en los servicios.
Mode characteristics for gapless-coupled twin circular-side square microcavity lasers

Published: February 2021

We propose gapless-coupled twin circular-side square microcavities (TCSMs), and experimentally demonstrate the TCSM semiconductor lasers with weak mode coupling. The introduction of circular sides modifies the field distributions of the whispering-gallery modes and enables gapless coupling for the TCSMs without degrading the mode quality factors. Numerical simulation results show crossing and avoided crossing of the modes in the TCSMs with the variation of the wavelength difference and gain-loss contrast between the two cavities. By tuning the injection currents of the laser cavities, mode crossing is observed from the experimental lasing spectra of a TCSM laser. The realization of weak mode coupling in TCSM lasers indicates that the gapless-coupled deformed square microcavities provide a feasible robust coupling scheme for photonic integration.

Saccharomyces cerevisiaeis the primary yeast species responsible for most fermentations in winemaking. However, other yeasts, includingSaccharomyces uvarum, have occasionally been found conducting commercial fermentations around the world.S.uvarumis typically associated with white wine fermentations in cool-climate wine regions, and has been identified as the dominant yeast in fermentations from France, Hungary, northern Italy, and, recently, Canada. However, little is known about how the origin and genetic diversity of the CanadianS.uvarumpopulation relates to strains from other parts of the world. In this study, a highly diverseS.uvarumpopulation was found dominating uninoculated commercial fermentations of Chardonnay grapes sourced from two different vineyards. Most of the strains identified were found to be genetically distinct fromS.uvarumstrains isolated globally. Of the 106 strains ofS.uvarumidentified in this study, four played a dominant role in the fermentations, with some strains predominating in the fermentations from one vineyard over the other. Furthermore, two of these dominant strains were previously identified as dominant strains in uninoculated Chardonnay fermentations at the same winery two years earlier, suggesting the presence of a winery-resident population of indigenousS.uvarum. This research provides valuable insight into the diversity and persistence of non-commercialS.uvarumstrains in North America, and a stepping stone for future work into the enological potential of an alternativeSaccharomycesyeast species.
The role of family meal frequency in common mental disorders in children and adolescents over eight months of follow-up
Authors: Agathão Beatriz Tosé , Cunha Diana Barbosa , Sichieri Rosely , Lopes Claudia Souza
Published: February 2021

Objective

This study evaluated the influence of family meal frequency on the occurrence of common mental disorders (CMD) in children and adolescents over eight months of follow-up.

Design

Data from this longitudinal study were derived from the PAAPAS—Parents, Students, Community Health Agents, and Teachers for Healthy Eating—community trial. CMD were evaluated using the General Health Questionnaire. Frequency of family meals (breakfast and dinner) was categorized as “breakfast and dinner regularly with the family”, “at least breakfast or dinner regularly with the family”, and “does not have any meal regularly with the family.” The effect of family meal frequency on CMD was analyzed using generalized estimation equations with log-binomial models for repeated measures.

Setting

This study was conducted in public schools (N = 18) of Duque de Caxias, Rio de Janeiro, Brazil, in 2016.

Participants

Children (aged 9–11 years) and adolescents (aged 12–17 years) from the fifth and sixth grades (N = 2,743).

Results

These findings suggested that regular family meals were a protective factor for mental health. The adjusted relative risk of CMD was 0.75 (95% confidence interval = 0.69–0.83) for those who had two family meals regularly and 0.87 (95% confidence interval = 0.77–0.97) for those who had only one regular family meal, compared to students who had no regular family meals.

Conclusions

Potential strategies that educate and encourage families about the mental health benefits of eating regular meals together must be explored and implemented.

Background

Internet addiction is a serious problem that can negatively impact both the physical and mental health of individuals. The Internet Addiction Test (IAT) is the most common used instrument to screen internet addiction worldwide. This study sought to investigate the psychometric properties of an Indonesian version of the IAT.

Methods

The IAT questionnaire was made the focus of forward translation, expert panel discussions, back translation, an item analysis (30 subjects), a pilot study (385 subjects), and field testing (643 subjects). Factor structure was analysed by exploratory (EFA) and confirmatory factor (CFA) analyses, whereas reliability was measured with Cronbach’s alpha coefficient.

Results

Factor analysis revealed that the Indonesian version of IAT, consisted of 3 domains, and had good validity (χ2 p < 0.001; RMSEA = 0.076; CFI = 0.95; SRMR = 0.057, and AIC = 784.63). The Cronbach’s alpha score is 0.855. A significant association was also observed between the level of internet addiction with gender (p = 0.027) and the duration of internet use per day (p = 0.001).

Conclusion

The Indonesian version of IAT provides good validity and reliability in a three-dimensional model. Therefore, it can be utilised as a tool for screening internet addiction in the Indonesian population.
SLAM-based augmented reality for the assessment of short-term spatial memory. A comparative study of visual versus tactile stimuli
Authors: Munoz-Montoya Francisco , Juan M.-Carmen , Mendez-Lopez Magdalena , Molla Ramon , Abad Francisco , Fidalgo Camino
Published: February 2021

The assessment of human spatial short-term memory has mainly been performed using visual stimuli and less frequently using auditory stimuli. This paper presents a framework for the development of SLAM-based Augmented Reality applications for the assessment of spatial memory. An AR mobile application was developed for this type of assessment involving visual and tactile stimuli by using our framework. The task to be carried out with the AR application is divided into two phases: 1) a learning phase, in which participants physically walk around a room and have to remember the location of simple geometrical shapes; and 2) an evaluation phase, in which the participants are asked to recall the location of the shapes. A study for comparing the performance outcomes using visual and tactile stimuli was carried out. Fifty-three participants performed the task using the two conditions (Tactile vs Visual), but with more than two months of difference (within-subject design). The number of shapes placed correctly was similar for both conditions. However, the group that used the tactile stimulus spent significantly more time completing the task and required significantly more attempts. The performance outcomes were independent of gender. Some significant correlations among variables related to the performance outcomes and other tests were found. The following significant correlations among variables related to the performance outcomes using visual stimuli and the participants’ subjective variables were also found: 1) the greater the number of correctly placed shapes, the greater the perceived competence; 2) the more attempts required, the less the perceived competence. We also found that perceived enjoyment was higher when a higher sense of presence was induced. Our results suggest that tactile stimuli are valid stimuli to exploit for the assessment of the ability to memorize spatial-tactile associations, but that the ability to memorize spatial-visual associations is dominant. Our results also show that gender does not affect these types of memory tasks.

The purpose of this study was to determine the energy partition of pregnant F1 Holstein x Gyr with average initial body weight (BW) of 515.6 kg and Gyr cows with average initial BW of 435.1 kg at 180, 210 and 240 days of gestation, obtained using respirometry. Twelve animals in two groups (six per genetic group) received a restricted diet equivalent to 1.3 times the net energy for maintenance (NEm). The proportion of gross energy intake (GEI) lost as feces did not differ between the evaluated breeds and corresponded to 28.65% on average. The daily methane production (L/d) was greater for (P<0.05) F1 HxG compared to Gyr animals. However, when expressed as L/kg dry matter (DM) or as percentage of GEI there were no differences between the groups (P>0.05). The daily loss of energy as urine (mean of 1.42 Mcal/d) did not differ (P>0.05) between groups and ranged from 3.87 to 5.35% of the GEI. The metabolizable energy intake (MEI) of F1 HxG animals was greater (P < 0.05) at all gestational stages compared to Gyr cows when expressed in Mcal/d. However, when expressed in kcal/kg of metabolic BW (BW0,75), the F1 HxG cows had MEI 11% greater (P<0.05) at 240 days of gestation and averaged 194.39 kcal/kg of BW0,75. Gyr cows showed no change in MEI over time (P>0.05), with a mean of 146.66 kcal/kg BW0. 75. The ME used by the conceptus was calculated by deducting the metabolizable energy for maintenance (MEm) from the MEI, which was obtained in a previous study using the same cows prior to becoming pregnant. The values of NEm obtained in the previous study with similar non-pregnant cows were 92.02 kcal/kg BW0.75 for F1 HxG, and 76.83 kcal/kg BW0.75 for Gyr (P = 0.06). The average ME for pregnancy (MEp) was 5.33 Mcal/d for F1 HxG and 4.46 Mcal/d for Gyr. The metabolizability ratio, averaging 0.60, was similar among the evaluated groups (P>0.05). The ME / Digestible Energy (DE) ratio differed between groups and periods evaluated (P<0.05) with a mean of 0.84. The heat increment (HI) accounted for 22.74% and 24.38% of the GEI for F1 HxG and Gyr cows, respectively. The proportion of GEI used in the basal metabolism by pregnant cows in this study represented 29.69%. However, there were no differences between the breeds and the evaluation periods and corresponded to 29.69%. The mean NE for pregnancy (NEp) was 2.76 Mcal/d and did not differ between groups and gestational stages (P>0.05).

Fondé sur l’analyse de décors ornementaux (portails, tombeaux et retables) sculptés par Jehan de Rouen au Portugal entre 1528 et 1580, cet article interroge la place du sculpteur dans les transferts artistiques entre l’Italie, la France, l’Espagne et le Portugal dans le domaine de l’ornement sculpté durant la première moitié du XVIe siècle. Après avoir précisé les modèles d’ornement utilisés par le sculpteur et contextualisé son oeuvre dans le panorama artistique européen de la première moitié du XVIe siècle, l’examen attentif de son oeuvre conduit à isoler des traits caractéristiques laissant à penser qu’il est à l’origine de certaines inventions.
Prospects on Solving an Optimal Control Problem with Bounded Uncertainties on Parameters using Interval Arithmetics
Authors: Bertin Etienne , Brendel Elliot , Hérissé Bruno , Alexandre dit Sandretto Julien , Chapoutot Alexandre
Published: February 2021

An interval method based on the Pontryagin Minimum Principle is proposed to enclose the solutions of an optimal control problem with embedded bounded uncertainties. This method is used to compute an enclosure of all optimal trajectories of the problem, as well as open loop and closed loop enclosures meant to enclose a concrete system using an optimal control regulator with inaccurate knowledge of the parameters. The differences in geometry of these enclosures are exposed, as well as some applications. For instance guaranteeing that the given optimal control problem will yield a satisfactory trajectory for any realization of the uncertainties or on the contrary that the problem is unsuitable and needs to be adjusted.

A felsőoktatás fejlődésének ingadozásai Fluctuations in the development of higher education
Authors: Polónyi István
Published: February 2021

Ebben az írásban a felsőoktatás fejlődésében tapasztalható ingadozásokat elemezzük. Az elemzés a felsőoktatás elmúlt mintegy ötven évének hazai és nemzetközi fejlődését veszi górcső alá, s arra keresi a választ, hogy az autonómia mennyiben befolyásolja a felsőoktatási részvétel ingadozásait. A felsőoktatás teljes részvételi arányának növekedésében tapasztalható ingadozások nemzetközi összehasonlításban azt mutatják, hogy a magyar ciklikusság az egyik legnagyobb mind 1970 előtt, mind 1987 után. Az államszocialista idő-szak felsőoktatási ciklikussága régről ismert jelenség [Bauer, 1981; Bródy, 2000], ugyan-akkor az ezredforduló után tapasztalható ingadozásnak kevésbé vizsgáltak az okai. Vizsgálatainkat úgy interpretálhatjuk, hogy a felsőoktatás teljes részvételi hányadának éves ingadozásait a GDP és a releváns korosztály létszámának éves ingadozásai növelik, az egyetemi autonómia pedig csökkenti. Elemzésünk tehát arra utal, hogy ezeknek az ingadozásoknak a GDP és a korosztályi létszám ingadozásai mellett a felsőoktatási intézmények autonómiájában – annak korlátozásában – lelhetők meg a magyarázatok.
Az Ipar 4.0 hatásai az ellátási láncok mentén – a gyógyszeripar példája Industry 4.0 Along Supply Chains – The Case of the Pharmaceutical Industry
Authors: Fetter Barbara Kitti , Zilahy Gyula
Published: February 2021

Jelen tanulmány első felében a szakirodalom alapján összefoglaljuk az Ipar 4.0 technológiai újításai-nak várható hatásait a gyógyszeripari ellátási láncokra, majd megvizsgáljuk, hogy mindezen változások milyen lehetőségeket és kihívásokat jelentenek a gyógyszeripar vállalatai számára. A problémakör feltárása érdekében a szakirodalom elemzését követően kétlépcsős kutatásmódszert al-kalmazunk. Kutatásunk első részben a szakirodalmi megállapítások kiegészítéseként feltáró jellegű mé-lyinterjúkat folytattunk le három hazai gyógyszeripari nagyvállalat képviselőivel. A kutatás második részében a mélyinterjúk során szerzett ismereteket hasznosítva strukturált kérdőív segítségével tártuk fel, hogy mit jelent a hazai gyógyszeripari kis- és középvállalatok számára az Ipar 4.0 térnyerése.A kutatás leg főbb eredménye annak megállapítása, miszerint az Ipar 4.0 hatására a gyógyszeripari nagyvállalatok monopolisztikus helyzete várhatóan tovább fog növekedni, a gyógyszeripari kis- és mikrovállalkozások erőforrások és kormányzati támogatások hiányában elveszíthetik piaci versenyképességüket, mindez pedig a gyógyszeripari ellátási láncok átalakulásához és a külföldi (például kínai) beszállítók befolyásának növekedéséhez vezethetnek.
A Comparison of Mediterranean Refugee Camps: The Situation of Asylum Seekers and Refugees in Greece and Italy
Authors: Paul Sebastian
Published: February 2021

The article examines the situation of asylum seekers and refugees in Italy and Greece with a particular focus on conditions in refugee camps. Whereas Italy can provide relatively acceptable living conditions in camps but fails to address the issue of homeless migrants in provisional camps, the situation in Greece is devastating. The Mediterranean countries are incapable of improving living conditions for migrants, and reasons for fleeing remain high. This paper compares the situation in both countries, and the findings emphasize the structural differences between Greece and Italy in terms of economy, location, policy imp-lications, and the origin of asylum seekers and refugees.

The paper presents models of the intrusion detection process based on three machine learn-ing methods: the decision tree method, the nearest neighbor method and the random forest method. The main task in modeling is to classify the ACS states (abnormal, normal). Parameters affecting the detection of anomalous behavior are considered: protocol, service data, flags used, number of unsuccessful attempts to enter, duration of the attack. To simulate the process of anomaly detection, the data set of the transport and network level of the control system, consisting of raw TCP/IP dumps in a situation where the network has been subjected to multiple attacks, was selected. For each TCP/IP connection, 3 qualitative and 38 quantitative features were recorded, among which the most important features affecting the learning were high-lighted. The response was predicted in a control (test) sample. The main criteria for choosing a mathematical model for the task were the number of correctly recognized (accuracy) anoma-lies, accuracy (precision) and completeness (recall) of answers. The optimal algorithm for detec-tion of anomalies was chosen on the basis of the conducted research

The transmission of information by means of visible light intensity modulation is confirmed by the works of many authors and the existence of a Li-Fi data transmission network. The wide-spread use of led lighting controlled by controllers potentially creates a channel for acoustic information leakage through visible light modulation. In this paper, the authors consider the block diagram of the device for detecting the channel of information leakage. The authors sug-gest using a modern smartphone running Android OS to determine the modulation of the re-fresh rate detected by the smartphone’s light sensor
