La educación en tiempos de COVID-19: El caso de Canarias. Entrevista a los expertos Manuel Area y Pablo J. Santana
Authors: García de Paz Sergio 
Published: February 2022

La declaración del Estado de Alarma en marzo de 2020 supuso el cierre de todos los centros educativos en España, desde educación infantil hasta la universidad, así como de educación de personas adultas. El sistema educativo español transitó hacia un modelo de educación a distancia para garantizar la continuidad de la actividad lectiva y el consecuente derecho a la educación. Todos los estudios coinciden al afirmar que se trató de un paso súbito, inesperado y carente de planificación.
La reapertura de los centros en septiembre de 2020 ha venido acompañada de numerosas medidas destinadas a prevenir la propagación de la pandemia. El inicio del curso 2020/2021 se ha visto estrechamente ligado a una reflexión sobre la contingencia de diversos escenarios de presencialidad, así como a las repercusiones que de ellos se derivan en cuestiones organizativas y pedagógicas. Entre otros aspectos, los equipos educativos de los centros se han visto motivados a considerar: la adaptación de los modelos de aprendizaje social a consecuencia de las medidas de distanciamiento, la naturaleza del uso de la tecnología digital en los distintos programas formativos, la reorganización de los espacios y de los recursos, la pertinencia de los modelos metodológicos presentes hasta el momento o el papel que los distintos agentes educativos venían desempeñando en el seno de la comunidad educativa.
La evolución del primer trimestre del curso se ha caracterizado por un incremento de la incidencia de personas afectadas por COVID-19, lo cual ha afectado de manera desigual a los centros de los distintos niveles educativos. Los escenarios de educación presencial se han mantenido más estables en educación infantil y educación primaria, por ejemplo, si bien han presentado mayor irregularidad en la educación universitaria. Este fue el caso de la Universidad de La Laguna, la cual procedió a la suspensión de la actividad lectiva presencial por el incremento de la incidencia en Tenerife en diciembre de 2020.
¿Cuál es el potencial pedagógico de las TIC y cómo deben integrarse en los programas formativos? ¿Cómo han afectado las medidas de distanciamiento social en las propuestas organizativas y pedagógicas de los centros educativos? ¿Son las medidas asumidas en España en general y en Canarias en particular equiparables a las que se han adoptado en otros países? A esta y a otras preguntas nos responden dos expertos en organización escolar y tecnología educativa de la Universidad de La Laguna, los profesores Manuel Area Moreira y Pablo J. Santana Bonilla.
Queremos expresar nuestro agradecimiento a ambos por haber participado de manera desinteresada en esta entrevista. Sus años de experiencia y su visión en el campo de la tecnología educativa y de la organización escolar nos ofrecen un horizonte más que adecuado para afrontar los retos de la educación en las próximas décadas.

Badminton players’ trajectory under numerical calculation method
Authors: Chi Jiaqing , Alahmadi Dimah 
Published: February 2022

Abstract
The trajectory tracking of badminton players’ arm shots can be used effectively to enhance the player’s shot quality. To track the image trajectory of the batting arm, it is necessary to calculate the body posture ratio and tightness of the target area of the batting arm, to filter the background interference of the image segment of the batting and to complete the efficient tracking of the trajectory of the arm batting image. The traditional method combines the adaptive threshold segmentation method to extract the hitting arm target from the background, but ignores filtering out the background interference of the hitting image fragment. This paper proposes a trajectory tracking method based on the morphological operator of the batter image of the arm stroke. The method consists of (1) differentially calculating the image sequence of the hitting arm during two consecutive shots, (2) estimating the Gaussian model parameters of the differential image of the hitting arm during the hitting process, (3) extracting the outline of the moving target of the hitting arm during the hitting process and then calculating the body posture ratio of the hitting target area and compactness, (4) filtering the background interference of the shot image fragment, (6) constructing a global matching approximation function of the moving target and (7) finally determining the motion trajectory of the badminton arm of the batter. Simulation results show that the proposed method can effectively track the target of the hitting arm during the hitting process and generate a continuous trajectory of the hitting arm.
The Atom of the Physical “Reality” or the Essentiality of the Vacuum

Published: February 2022

Abstract
A correlation between the informational Universe and various structures of the Universe (atom, planetary systems, galaxy pairs etc.) are established. The link between these structures can be found in the concept of holography, which can be mathematically explicated through multifractality.
From Classical Newtonian Phylosophy to Skyrmion – A Short History
Authors: Mazilu Nicolae , Rusu Cristina-Marcela 
Published: February 2022

Abstract
This paper presents a short history from Philosophiae Naturalis Principia Matematica of Newton to skyrmions of Skyrme. It is shown that the classical mechanics does not exclude skyrmions (as topologically stable field configuration of a certain class of non-linear sigma models- for example nucleon model). In certain conditions the Newtonian Theory becomes fundamental in building of modern physics theories (as quantum mechanics, fields theories, etc.).
On the Holographic Type Dynamics in Complexity Economics
Authors: Agop Ștefana , Ștefan Gavril , Petrescu Tudor-Cristian , Saviuc Alexandra , Rusu Cristina-Marcela 
Published: February 2022

Abstract
Assimilating any complex economic system with a fractal, in the most general Mandelbrot’s sense, non – differentiable behaviors in its economic dynamics are analyzed. As such, economic dynamics in the form of Schrödinger – type various regimes imply “holographic implementations” of the economic processes through group invariance of SL(2R) – type. Then, by means of previous group invariance as synchronization group between any economic system entities, both the phases and the amplitudes of the entities are affected from a homographic perspective. The usual “synchronization” manifested through the delay of the amplitudes and phases of the entities of the economic system must represent here only a fully particular case. In a special case of synchronization of economic system entities, given by Riccati type gauge, period doubling, damping oscillations, self – modulation and chaotic regimes emerge as natural behaviors in the economic dynamics of the economic processes.
Directing young dropouts via SMS: evidence from a field experiment
Authors: Hervelin Jérémy 
Published: February 2022

Abstract
Although short message services (SMS) are constantly used to transmit information, little is known about the use of SMS by public institutions to direct people. This paper presents a field experiment in France about the effectiveness of SMS in directing disadvantaged people toward public services. Two types of treatment SMS were provided: one type had its content written in a formal style; the second type SMS style was much informal. All the SMS were individualized and included specific information about the agencies. Results indicate that the SMS had no significant effect on enrollment. There is also no apparent heterogeneous effect according to individual, agency, or location characteristics. In line with other academic evidence, these findings suggest that SMS have very limited effectiveness in directing this population toward public services.

Abstract
The present study aimed to evaluate the changes in concentrations of some biochemical parameters, as well as macro and microscopic alterations during Eimeria stiedae infection in rabbits. The experiment was performed using 12 three-month-old healthy rabbits, randomly allocated into 2 equal groups: G1 (controls, uninfected animals) and G2 (rabbits infected with E. stiedae). Blood samples were collected at time zero (prior to the infection), 6th, 24th, and 48th hours, and also 7th, 14th, 21st, 28th days after the infection. After sampling, the blood was centrifuged, plasma was separated and frozen at -20 ºC until analyzed. Thawed plasma was used for the quantitative determination of haptoglobin (Hp), total protein (TP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP), total cholesterol (TC), total bilirubin (TBIL), urea, and creatinine (CREA). The results in infected rabbits revealed a significant increase in Hp, AST, ALT, GGT, TBIL, and TC levels, as well as a significant decrease in ALP and urea. A weak hyperproteinemia was also observed. There were no changes in CREA concentration. At the end of the clinical investigation, all rabbits were humanely euthanized and necropsied. The post-mortem examination of the infected group revealed hepatomegaly, multifocal yellowish nodules diffusely spread over the liver surface and in the parenchyma, considerably dilated bile ducts, and biliary hyperplasia. Given the results obtained from this experiment, it can be affirmed that hepatic eimeriosis in rabbits is a severe parasitic disease leading to significant disturbances of liver histology and resulting changes in the biochemical profile of infected rabbits.
Failure and opportunities of public value capture and developer obligations in Polish urban development
Authors: Gielen Demetrio Muñoz , Ossowicz Tomasz , Zaborowski Tomasz Piotr 
Published: February 2022

Abstract
As many countries pursue private financing for urban public infrastructure, the tools for public value capture (PVC) gain prominence. This paper analyses Polish PVC tools in general, and spotlights a specific type: developer obligations (DOs). The authors conclude that the tools are ineffective for a series of reasons: negligence in the elaboration of pragmatic rationales (to mitigate the negative impacts of urban development), a lack of feasible (affordable) coercive land policy tools, and legislation (which puts Poland in sharp contrast to other countries) that prohibits municipalities from requiring DOs in exchange for approval of a land-use plan or planning permit, as well as the general ban on securing such obligations in a planning agreement (except for specific situations introduced by recent laws that have not yet been applied). As a consequence, new urban development in Poland neither includes sufficient urban public infrastructure, nor does it provide for social/affordable housing.

Pengaruh Absorpsi Kalsium oleh Vitamin D Pada Penderita Obesitas
Authors: Aji Nabila Jemima , Fitriani Anna 
Published: February 2022

Latar belakang: Obesitas terus mengalami peningkatan setiap tahunnya akibat perubahan gaya hidup sehingga mempengaruhi asupan makan dan aktivitas fisik pada setiap orang. Selain berisiko terkena penyakit degeneratif, penderita obesitas juga berisiko terkena penyakit pada tulang seperti, osteomalasia, osteopenia, dan riketsia. Penderita obesitas membutuhkan kekuatan tulang yang lebih kuat untuk menopang tubuhnya dibandingkan dengan orang yang memilki berat badan normal. Untuk membentuk tulang yang lebih kuat dibutuhkan asupan kalsium yang tinggi. Vitamin D sangat berperan untuk mengoptimalkan absorbsi kalsium dalam tubuh. Tujuan: Untuk mengetahui pengaruh absorbsi kalsium oleh vitamin D pada obesitas. Hasil: Obesitas mempengaruhi biovailabilitas vitamin D dalam tubuh akibat tingginya jaringan adiposa dan rendahnya paparan terhadap sinar matahari. Rendahnya kadar vitamin D dalam tubuh akan menurunkan absorbsi kalsium. Simpulan: Kadar vitamin D pada penderita obesitas memang secara langsung mempengaruhi absorbsi kalsium dalam tubuh. Namun penelitian lebih lanjut dan mendalam diperlukan untuk membuktikan bahwa penderita obesitas memiliki faktor risiko langsung terhadap penyakit pada tulang seperti osteomalasia, riketsia, dan osteoporosis akibat rendahnya absorbsi kalsium dari pengaruh rendahnya kadar vitamin D dalam tubuh.

Из года в год на дорогах страны производят ремонтные работы. По многочисленным исследованиям плохое качество дорожного покрытия связано, как с качеством выполняемых работ, так и качеством асфальтобетонного покрытия. Уровень усталостного разрушения дорожных покрытий в основном определяется прочностными, деформационными и усталостными свойствами асфальтобетонного покрытия и зависят, прежде всего, от свойств вяжущих компонентов. Статья посвящена изучению причин снижения нормативного срока эксплуатации дорожных покрытий от температурных колебаний, а также эффективности применения серы, в качестве добавки к битуму, при строительстве дорожных покрытий.
From year to year on the roads of the country carry out repair work. According to numerous studies, the poor quality of the road surface is associated both with the quality of the work performed and the quality of the asphalt concrete pavement. The level of fatigue fracture of road surfaces is mainly determined by the strength, deformation and fatigue properties of asphalt concrete pavement and depends, fi rst of all, on the properties of cementitious components. The article is devoted to the study of the reasons for reducing the regulatory life of road surfaces from temperature fl uctuations, as well as the effectiveness of the use of sulfur, as an additive to bitumen, in the construction of road surfaces.

ARENDT E TOCQUEVILLE E AS POTENCIALIDADES DA AÇÃO COLETIVA
Authors: Chaves Rosângela 
Published: February 2022

Embora fosse manifesta a admiração de Hannah Arendt pela obra de Alexis de Tocqueville, ela nunca explorou de maneira mais consistente o pensamento dele em seus textos. No entanto, apesar da pouca visibilidade que Arendt confere ao autor da Democracia na América em sua obra, é marcante a afinidade entre os dois autores na forma de pensar a política e as potencialidades da ação coletiva. O artigo começa como uma breve explanação sobre em que aspectos da obra de Arendt, desde Origens do totalitarismo, é possível perceber a influência de Tocqueville, para depois explorar três pontos em que é se pode perceber uma vísivel confluência entre os dois autores: o diagnóstico que apresentam das Revoluções Americanas e Francesa, sobretudo na preocupação de ambos com a desafio da criação e da preservação de instituições livres; a compreensão mútua da liberdade como sinônimo de liberdade política, e a ênfase em formas de autogoverno como as comunas (no caso de Tocqueville) e os conselhos populares (no caso de Arendt), além das associações voluntárias, como caminhos para garantir a participação popular e a experiência da liberdade política.
ENSINO DE FILOSOFIA: ONDE RESIDE O PROBLEMA?
Authors: Silva Alves Maurício 
Published: February 2022

Há de fato, uma diferença entre as duas carreiras docentes, e não é em essência, mas em condições de trabalho, uma para as a realização pessoal e profissional e outra que não oferece a mesma possibilidade. Nesse sentido, desenvolver um ensino de filosofia eficaz, pressupõe não só a utilização dos textos clássicos dos filósofos que fizeram e promoveram a perpetuação da filosofia como apenas mais uma disciplina do currículo, mas como um distintivo que possibilite o desenvolvimento da criticidade dos alunos do Ensino Médio por meio de um tratamento contextualizado do programa da disciplina. Finalmente, ao contrário do que defendem muitos críticos do ensino da Filosofia no Ensino Médio, a presença da filosofia associada aos textos filosóficos em conexão com os demais componentes curriculares numa prática interdisciplinar, está longe de levar os adolescentes a uma eventual adesão a propostas ideológicas, de doutrinação e possível adesão ao dogmatismo, ela é condição primordial para que se revistam de uma postura crítica frente aos dogmas que impregnam não só o senso comum da contemporaneidade, mas também os dogmatismos que perpassam até mesmo o discurso científico.

A CORRELAÇÃO ENTRE AS NOÇÕES DE “VONTADE” E “MEDIDA” NO DIÁLOGO DE BEATA VITA DE SANTO AGOSTINHO
Authors: Martins Silva Josadaque 
Published: February 2022

Este artigo pretende analisar a correlação entre as noções de “vontade” e “medida” no diálogo De beata vita de Santo Agostinho, tendo em vista dois motivos: primeiro, porque o tema da felicidade, no De beata vita, não se reduz à identificação de uma realidade que satisfaça o desejo de ser feliz, mas relaciona-se diretamente com o tema da vontade, pois o desejo de felicidade é desejo de um bem imutável (Deus); e segundo, porque o estudo da correlação entre as noções de “vontade” e “medida” no De beata vita é central para compreender o sentido atribuído por Santo Agostinho à sabedoria como medida da alma (e, portanto, como orientadora da vontade), no processo de busca da felicidade.
