El profesor ante la formación de valores. Aspectos teóricos y prácticos
Authors: Estrada Molina Odiel 
Published: July 2021

Se exponen las principales teorías del desarrollo de la moral y enfoques teóricos sobre el proceso de formación de valores desde una perspectiva psicopedagógica, aludiendo a las teorías de Henry Wallon, Jean Piaget y Lev Semionovich Vigotsky, además de sus conceptos asociados desde diferentes enfoques teóricos como: el psicoanalítico de S. Freud, el conductista y neoconductista de A. Bandura y R.H. Walters, el cognitivista Jean Piaget y Kohlberg, y por último el enfoque histórico-cultural de L.S. Vigotsky. Se presentan métodos educativos, herramientas, actitudes y aspectos necesarios que deben tener en cuenta los profesores universitarios en la educación en valores, como: 1) la concientización de los valores como reguladores de la actuación del individuo; 2) la doble moral: disfraz de la verdadera conducta del individuo; 3) la caracterización psicopedagógica; 4) la conciencia, la actividad y la valoración como métodos educativos en la formación de valores; y 5) la posición profesional de los educadores ante los tipos de valores a formar. Se argumenta desde una perspectiva psicopedagógica la teoría de Lev Semionovich Vigotsky y continuadores suyos como L.I. Bozhovich, Subbotsky y Kraftchenko, en cuanto a la formación de valores desde lo colectivo y hacia lo colectivo.

Objective: To evaluate the efficacy of different fluoride varnishes on white spot lesions (WSL) remineralization. Material and Methods: Polished bovine enamel specimens were obtained (n = 60) and had their initial surface Knoop microhardness (SMH) determined. WSL were created and the SMH was measured again. Then, specimens were allocated into six groups: C – Control (without varnish); BF – Bifluorid 12 (6% NaF + 6% CaF2); DP – Duraphat (5% NaF); PF – Profluorid (5% NaF); FP - Fluor Protector (0.2% NaF + 0.9% difluorsilane); CW - Clinpro White Varnish (5% NaF + 5% TCP). After varnishes application, specimens were immersed in artificial saliva for 24 h. Then, pH-cycling was performed for 8 days and SMH was measured. Data were analyzed by one-way ANOVA and Tukey’s test. Results: Non-significant differences were observed among the groups at baseline (p = 0.187) and after WSL formation (p = 0.999). After treatments, significant differences were observed among the groups (p = 0.001). Mean % of alteration (SD) and results of Tukey test were: C- 92.40 (12.10)a; PF- 88.66 (10.66)a; FP- 85.90 (14.49)ab; BF- 67.85 (17.86)bc; CW- 66.60 (18.48)c; DP- 58.62 (8.69)c. Conclusion:. Bifluorid 12, Clinpro White Varnish, and Duraphat showed higher efficacy than artificial saliva in promoting the remineralization of WSL, nevertheless, none of the treatments were able to recover sound enamel baseline microhardness.

Objective: To evaluate the biochemical and histopathological effects of diclofenac and ketoprofen administration on bone regeneration in a calvarial defect model in rats. Material and Methods: The sample consisted of 108 Wistar rats that were randomly distributed in three groups, to which an osteotomy of 6 mm in diameter was performed in the calvaria. Group A (control) was given saline solution; Group B received ketoprofen 2 mg/kg and Group C received diclofenac 2 mg/kg. All treatments were administered intraperitoneally every 12 hours for 3 days. Bone regeneration was evaluated by biochemical (alkaline phosphatase and serum calcium) and histopathological (osteocyte and osteoblast cell count) characteristics at 15 and 30 days. Results: In the biochemical evaluation, alkaline phosphatase levels in the ketoprofen group were significantly lower compared to the diclofenac group at 15 and 30 days (p= 0.015 and p= 0.001; respectively). However, serum calcium levels did not show the difference between the study groups at 15 and 30 days (p= 0.42 and p= 0.81; respectively). In the histopathological analysis, the count of osteoblasts and osteocytes was significantly lower in the ketoprofen group compared to the diclofenac group at 15 and 30 days (p< 0.05). Conclusion: The administration of ketoprofen has negative biochemical and histopathological effects of greater intensity on bone regeneration compared to the administration of diclofenac.

A descentralização é um dos princípios que remete a avanços significativos na construção do Sistema Único de Saúde (SUS), pois rompe com o modelo centralizado na assistência e redistribui recursos e responsabilidades entre os entes federativos, passando a gestão do Sistema de Saúde ser uma responsabilidade compartilhada pela União, Estados e Municípios. Tal avanço descortina por outro lado inúmeros desafios, muitos deles inscritos no âmbito municipal, em que os gestores assumem papel fundamental para que as ações e serviços ofertados estejam em consonância com as necessidades particulares de cada região. Compreender os desafios inscritos na gestão do SUS sob a perspectiva dos gestores municipais de saúde de uma microrregião de saúde de Minas Gerais. Pesquisa descritiva, de natureza qualitativa, que tem como participantes os gestores municipais de saúde de uma microrregião de saúde da Zona da Mata de Minas Gerais, composta por nove municípios. A coleta de dados iniciou-se no mês de junho de 2016, por meio de um roteiro de entrevista com questões abertas. Os dados estão sendo analisados à luz de Bardin e serão interpretados e discutidos em consonância com a literatura pertinente à temática. Cabe ressaltar que a coleta de dados encontra-se ainda em andamento, sendo realizada uma análise parcial dos dados coletados até o momento. O projeto foi aprovado pelo Comitê de Ética em Pesquisa com Seres Humanos da Universidade Federal de Viçosa, inscrito sob o Parecer nº1.147.443. A pesquisa permite preliminarmente evidenciar que os desafios inscritos na gestão do SUS estão relacionados ao subfinanciamento –repasse defasado e aquém do contratualizado, implicando em sobrecarga do ente municipal – ; à morosidade do sistema – em especial no tocante à marcação de cirurgias eletivas –; à gestão dos recursos humanos – relacionada à desqualificação de profissionais com perfil para atuar no SUS e, por outro lado, à precarização do trabalho em saúde– ; à ausência de autonomia do gestor – com ênfase para a impossibilidade de manejar os recursos do fundo municipal de saúde –; ao incipiente controle social – marcado pela ausência de participação da população na saúde – e a deficiente formação do próprio gestor para gerir um sistema complexo como o SUS – evidenciado no fato de a maioria dos gestores não terem experiência prévia no setor saúde. Conclusão: ao conhecer os desafios enfrentados pelos gestores municipais de saúde espera-se que este estudo produza evidências que auxiliem pesquisadores, profissionais de saúde e os próprios gestores do SUS a reconhecer os nós críticos que permeiam a municipalização e a (re)pensar possíveis caminhos para superá-los.
Czy (i komu) potrzebne są czasopisma naukowe? Kontekst nauk społecznych
Authors: Brzeziński Jerzy Marian 
Published: July 2021

Badacze zajmują się: (1) prowadzeniem badań naukowych oraz (2) upowszechnianiem ich wyników. Badacze zatrudnieni na uniwersytetach podejmują jeszcze dodatkową aktywność – (3) przekazują intersubiektywną wiedzę naukową (sprawdzone teorie i metody pozyskiwania tej wiedzy) swoim studentom i młodym badaczom, przygotowującym pod ich kierunkiem dysertacje doktorskie. Głównym kanałem przekazywania naukowych treści (wypełnianie przez badaczy obowiązku poddawania społecznej kontroli wytworów ich umysłów) są czasopisma naukowe. Tak jest w matematyce, fizyce, chemii, biologii, naukach medycznych czy w naukach inżynierskich. Tak też – w interesujących autora naukach społecznych – jest w psychologii. Z kolei w naukach humanistycznych (filozofia, historia, literaturoznawstwo itp.) duże znaczenie przypisuje się monografiom naukowym.
Autor rozpatruje problem publikowania osiągnięć naukowych badaczy z obszaru nauk społecznych (ale jego rozważania mają też znaczenie dla klasycznych nauk humanistycznych) w czasopismach i w monografiach na tle dokonanych w Polsce – jego zdaniem - nieudolnie i bez należytego poszanowania tradycji, reform w obszarze nauki i szkolnictwa wyższego (tzw. ustawa Jarosława Gowina, ministra ds. nauki szkolnictwa wyższego, autoryzującego krytykowaną ustawę).
Autor krytycznie odnosi się do negatywnych konsekwencji społecznych – zwłaszcza dla rozwoju nauki i studiów wyższych w Polsce. Autor krytycznie odnosi się do: (1) uznaniowego (bez racjonalnego uzasadnienia!) wyróżnienia listy wydawców książek naukowych, (2) stworzenia, bez należytej wnikliwości, listy czasopism. Te dwa wykazy stanowią podstawę do przeprowadzanych ewaluacji dorobku naukowego instytucji naukowych i pojedynczych badaczy. To nie mogą być rzetelne oceny.
Zdaniem autora przeliczanie publikacji na punkty prowadzi do zjawiska depersonalizacji ocen osiągnięć naukowych (w wymiarze indywidualnym i instytucjonalnym). Prowadzi też do udziału, zwłaszcza młodych badaczy, w „wyścigu szczurów” (formuła: Publish or Perish) oraz rodzi zjawiska patologiczne w nauce: ghostwriting, guest authorship, plagiarism, self-plagiarism, falsification of data, fabrication of data, publikowanie w predatory journals, publication bias. Środkiem zaradczym może być tylko odejście od „punktowania” publikacji i dokonywanie ocen metodą peer review.

Abstract

Objectives
Lipid mediators are bioactive lipids which help regulate inflammation. We aimed to develop an ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method to quantify 58 pro-inflammatory and pro-resolving lipid mediators in plasma, determine preliminary reference ranges for adolescents, and investigate how total parenteral nutrition (TPN) containing omega-3 polyunsaturated fatty acid (n-3 PUFA) or n-6 PUFA based lipid emulsions influence lipid mediator concentrations in plasma.

Methods
Lipid mediators were extracted from plasma using SPE and measured using UHPLC-MS/MS. EDTA plasma was collected from healthy adolescents between 13 and 17 years of age to determine preliminary reference ranges and from mice given intravenous TPN for seven days containing either an n-3 PUFA or n-6 PUFA based lipid emulsion.

Results
We successfully quantified 43 lipid mediators in human plasma with good precision and recovery including several leukotrienes, prostaglandins, resolvins, protectins, maresins, and lipoxins. We found that the addition of methanol to human plasma after blood separation reduces post blood draw increases in 12-hydroxyeicosatetraenoic acid (12-HETE), 12-hydroxyeicosapentaenoic acid (12-HEPE), 12S-hydroxyeicosatrienoic acid (12S-HETrE), 14-hydroxydocosahexaenoic acid (14-HDHA) and thromboxane B2 (TXB2). Compared to the n-6 PUFA based TPN, the n-3 PUFA based TPN increased specialized pro-resolving mediators such as maresin 1 (MaR1), MaR2, protectin D1 (PD1), PDX, and resolvin D5 (RvD5), and decreased inflammatory lipid mediators such as leukotriene B4 (LTB4) and prostaglandin D2 (PGD2).

Conclusions
Our method provides an accurate and sensitive quantification of 58 lipid mediators from plasma samples, which we used to establish a preliminary reference range for lipid mediators in plasma samples of adolescents; and to show that n-3 PUFA, compared to n-6 PUFA rich TPN, leads to a less inflammatory lipid mediator profile in mice.
“The Nude Man’s City”: Flávio de Carvalho’s Anthropophagic Architecture as Cultural Criticism
Authors: Minkkinen Panu 
Published: July 2021

Abstract
Cannibalism is one of the most recognisable taboos of the West and a benchmark with which a supposedly civilised world has traditionally sought to differentiate itself from the radically “other” of the hinterlands. As such, cannibalism has made its way both into the vocabulary of the West’s pseudo-ethnographic self-reflection (e.g. Freud) and the imaginary of its literary culture (e.g. Grimm). A less-well-known strain in this narrative uses cannibalism as a critical postcolonial metaphor. In 1928, the Brazilian poet and agitator Oswald de Andrade published a short text entitled “Anthropophagic Manifesto.” The aim of the manifesto was to distance an emerging Brazilian modernism from the European ideals that the São Paulo bourgeoisie uncritically embraced, and to synthesise more avant-garde ideas with aspects from the cultures of the indigenous Amazonian peoples into a truly national cultural movement. This essay draws on various aspects of the anthropophagic movement and seeks to understand, whether (and how) it influenced Brazilian urban planning and architecture, and especially if it is detectable in the ways in which architects Lúcio Costa and Oscar Niemeyer designed and executed the legal and political institutions in Brasília, the country’s iconic federal capital. The ana-lysis, however, identifies a colonialist inclination in Costa and Niemeyer’s ideological debt to Le Corbusier. Instead, the radical potential of anthropophagic architecture is developed with reference to the less-known São Paulo architect and polymath Flávio de Carvalho whose aesthetic politics provide parallels with contemporary radical politics, as well. The essay suggests that such a notion of politics would be akin to a radical anti-instrumentalism that I have elsewhere, following Georges Bataille and Maurice Blanchot, called a “politics of the impossible.”
La descortesía de Donald Trump hacia los migrantes mexicanos y la respuesta de La Jornada en sus editoriales: la descortesía como práctica política
Authors: Bolívar Adriana , Escudero Ana 
Published: July 2021

Resumen
La descortesía de Donald Trump ha causado preocupación en su país y en casi todo el planeta por los efectos geopolíticos que su discurso racista, xenofóbico y misógino podría tener en la política mundial (Wodak y Krzyżanowski, 2017). En América Latina, México ha sido blanco de su discurso ofensivo y esto ha generado respuestas de diferentes sectores de la sociedad. En este trabajo, nos concentramos en la respuesta que el diario La Jornada ha dado a los insultos y amenazas contra los migrantes mexicanos y de otras nacionalidades desde su campaña electoral para presidente cuando amenazó con construir un muro entre Estados Unidos y México. Planteamos que aquí la descortesía es una práctica política de (auto)legitimación ideológica que amerita un estudio más allá de la construcción de la imagen social de los interlocutores individualmente porque, en este caso, se trata de una descortesía con implicaciones sociales, económicas y políticas para el diálogo internacional. Desde una perspectiva lingüística, interaccional y crítica (Bolívar, 2018, 2019) analizamos la situación, analizamos la situación entre México y EUA a través de los editoriales de La Jornada, concebidos como un espacio para el diálogo mediado por la prensa. Analizamos un corpus de editoriales que comprende de 2016 a 2020. El estudio revela cómo funciona la descortesía en la práctica política de Trump y la forma en que La Jornada responde en su rol de actor social.
From Slave to Bishop. Callixtus’ Early Ecclesial Career and Mechanisms of Clerical Promotion
Authors: Handl András 
Published: July 2021

Abstract
Bishop Callixtus I of Rome (217?–222?) is well known for his position as manager of the κοιμητήριον, the earliest subterranean community burial ground, today known as the Catacombs of Callixtus. Less well documented, but particularly formative is, however, Callixtus’ early ecclesial career starting with his recognition as an authentic confessor shortly after his return from the mines of Sardinia. This contribution aims to shed some light on this formative period and explores the mechanisms behind Callixtus’ promotion to paid ecclesial ministry. It argues that Callixtus’ association with the clergy was neither an honorary, that is, automatic admission, nor merely a pious act to honour his individual and spiritual achievement. It seems, it was also a powerful instrument to financially support, integrate, and if necessary, control independent spiritual authorities. Moreover, Callixtus’ installation in active ministry, as well as that of other confessors, show typical patterns of client-patron relationship.
A Review of Transnational Migrant Entrepreneurship: Perspectives on Unequal Spatialities

Published: July 2021

Abstract
The spatialities of migrant entrepreneurship have changed dynamically in recent decades. Movements and exchanges transcend national borders more than ever, and transnational migrant entrepreneurship has become a burgeoning field of research. Yet, knowledge is dispersed across disciplines, and an understanding of contemporary spatialities is limited. We review 155 articles published in English, French, German, and Spanish since 2009, thereby providing an overview of existing knowledge on transnational migrant entrepreneurship and suggesting avenues for future research. We identify five current topical areas of research: (1) the business advantages of transnational migrant entrepreneurship, (2) the determinants of becoming a transnational migrant entrepreneur, (3) the transnational networks of migrants, (4) the economic impacts of transnational migrant entrepreneurship on home and host countries, and (5) whether local environments enable or deter entrepreneurial success. Building on our synthesis of the most recent literature, we propose three crucial dimensions which have been under-researched in past and current work, and which address the diversity of geographical locations, spatial connections, and spatial mobilities involved in transnational migrant entrepreneurship. Moreover, we put forward a set of questions for future research which will advance a comprehension of unequal opportunities among transnational migrant entrepreneurs.
Análisis confirmatorio de un cuestionario de control y presión al comer en madres de preescolares costarricenses
Authors: Chacón Villalobos Alejandro 
Published: July 2021

Objetivo: analizar la validez de la estructura factorial para un cuestionario adaptado a partir del Preschooler Feeding Questionnaire (PFQ) con subescalas asociadas al control y la presión parental al comer. Metodología: se elaboró un cuestionario de 11 reactivos expresados con escalas tipo Likert y agrupados en dos subescalas: Presión Maternal al Comer y Control Maternal al Comer. Se evaluaron 50 madres y posteriormente se realizó un análisis factorial para identificar la estructura factorial subyacente, mediante la evaluación de la confiabilidad con el α de Cronbach, la extracción de componentes principales con una rotación Varimax y la normalización de Kaiser. Luego, se efectuó un análisis confirmatorio de factores con 430 madres. Por medio de la estadística descriptiva se estudiaron las prácticas parentales de «control» y «presión», mientras un modelo SEM valoró la existencia de relaciones causales entre el IMC, el género infantil y dichas prácticas. Resultados: se validó una estructura factorial de dos escalas, Control y Presión, compuestas cada una de tres reactivos (x2 = 187,3, df. = 116, x2/df. = 1,62, CFI = 0,998, GFI = 0,991, AGFI = 0,983, NFI = 0,994, IFI = 0,998, and RMSEA = 0,018). No se estableció relación causal alguna entre estos factores con el IMC o el género de los infantes, siendo ambos factores mayores a la media. Conclusión: la adaptación del formulario constituye una herramienta válida y fiable de futura utilidad en el estudio de prácticas nutricionales parentales.
Development of alternative steering models for ev bus: a preliminary study on the conversion of hydraulic to electric power steering

Published: July 2021

This study aims to develop alternative steering models for the EV bus. The EV bus uses its energy source from the main 384 VDC 300 Ah battery and the secondary battery with a capacity of 25.8 VDC 100 Ah. The use of energy in this electric bus is divided into the main components, namely the BLDC motor as the main drive of 200 kW, 15 kW of air conditioning, 7.5 kW of hydraulic power steering, a compressor for the air braking system of 4 kW, and accessory components. The other is 2.4 kW. It is expected that this 7.5 kW electric power can be reduced by an electric system by up to 20 %. This research will study the steering system with an electric power system (EPS) to convert the hydraulic steering system (HPS). With this EPS system, it is hoped that controlling the vehicle’s motion towards the steer by wire will be easier. Initially, data were collected from the types of large vehicles from various well-known brands about the steering system used. A large commercial vehicle that purely uses EPS is not yet found. The model developed for EPS on this electric bus is through the reverse engineering method by redrawing all the components involved in the previous steering system. Because this type of EV bus is included in the upper mid-size class, this paper proposes two new EPS models, namely the addition of an assist motor on the drag link and on the steering rack. The links involved in this system are wheel drive, steering column, lower steering column, rack and pinion gear, assist motor, drop link, drag link, drop link extension, drag link extension, tie rod, knuckle, kingpin, tire, axle beam and several others. The values of stiffness, inertia, and damping of each link will affect the driver’s torque and the assist motor as a wheel speed function on this electric bus. The steering structure of the EV bus consists of a truss structure and a frame structure with a kinematic structure consisting of two four-bar linkages joined together
