Pozycja konkurencyjna województwa wielkopolskiego wobec poziomu realizacji celów strategii „Europa 2020”
Authors: Grzebyk Bogumiła
Published: May 2021

Strategia „Europa 2020” wyznaczyła nowe cele w zakresie podnoszenia konkurencyjności i przyspieszenia rozwoju regionów i krajów UE. Kończąca się dekada uzasadnia dokonywanie ocen, które należy bezwzględnie powiązać z analizą wskaźników wyznaczonych przez KE w ramach trzech priorytetów strategii, tj. inteligentnego, zrównoważonego i sprzyjającego włączeniu społecznemu rozwoju. Z przedstawionych w artykule badań wynika, że obszarem, w którym Polska zdecydowanie plasuje się na ponadprzeciętnej pozycji w stosunku do innych krajów UE, jest edukacja, natomiast w przypadku województwa wielkopolskiego jest to udział energii ze źródeł odnawialnych w końcowym zużyciu energii brutto i udział osób zatrudnionych w wieku 20–64 lat. W dalszym ciągu jednak konkurencyjność polskich regionów, w tym Wielkopolski, klasyfikowana w ramach Indeksu Regionalnej Konkurencyjności oceniana jest bardzo nisko.

Authors: Koliński Krystian , Nowak Zuzanna
Published: May 2021

Ulica św. Marcin w Poznaniu stanowiła niegdyś jedno z ważniejszych miejsc na mapie Poznania, które tętniło życiem. Aby przywrócić dawny charakter przestrzeni, ulicę objęto projektem rewitalizacyjnym Centrum I, którego celem była rewaloryzacja przestrzeni publicznej, odnowa infrastruktury technicznej oraz uspokojenie ruchu samochodowego. Po zakończeniu prac remontowych i oddaniu części ulicy św. Marcin do użytku pojawiło się wiele opinii użytkowników badanej przestrzeni, mówiących, że jest ona wciąż niedostępna ze względu na obecność barier architektoniczno-urbanistycznych. Celem artykułu jest przedstawienie, jak działania rewitalizacyjne wpłynęły na poziom dostępności przestrzeni ulicy św. Marcin w Poznaniu. Autorzy odpowiedzą na pytanie, czy projekt rewitalizacyjny został stworzony i zrealizowany z uwzględnieniem zasad projektowania uniwersalnego.

Flutuação temporal de cianotoxinas (Microcistina) no rio Tapajós (Santarém, Amazônia-Brasil)
Authors: Silva Sâmea Cibele Freitas da , Peleja José Reinaldo Pacheco , Melo Sérgio
Published: May 2021

O relato de produção de microcistinas tem aumentado nas últimas décadas e é um problema preocupante em diversos ambientes aquáticos naturais e antropizados, em especial nos lênticos. Poucos são os relatos de presença de cianotoxinas em ambientes lóticos, entre estes está o registro no rio Tapajós. O presente estudo teve por objetivo analisar a ocorrência de microcistina em amostras de água coletadas em escala quinzenal no rio Tapajós (Santarém, PA, Brasil) em uma região de recreação ao longo de um ciclo anual. A concentração de microcistina foi quantificada pelo método Imunológico-ELISA. Ao longo do estudo foram registradas a ocorrência de 11 táxons de cianobactérias, sendo Microcystis, Dolichospermum e Planktothrix os gêneros que apresentam espécies potencialmente produtoras de cianotoxinas. A presença de microcistina foi constatada em todo o período amostrado e sua concentração máxima esteve associada à presença de espécies do gênero Microcystis sp. Embora os valores constatados sejam inferiores aos considerados como limite para o uso recreativo, a ocorrência de gêneros de cianobactérias, potencialmente produtores de cianotoxinas, e o fato da detecção de microcistina em todo o período de estudo, torna-se importante os estudos sobre este grupo de microrganismos no rio Tapajós. Temporalmente, não foi constatado diferenças significativas dos níveis de microcistina em relação ao regime pluviométrico e ao pulso de inundação.
(In)acessibilidade arquitetônica e suas implicações para a permanência da pessoa com deficiência visual no ensino superior
Authors: De Abreu Araújo José Douglas , Barreto Silva Maria Aurinolia , Andrade da Silva Wanderson Diogo
Published: May 2021

O processo de inclusão da pessoa com deficiência nas instituições de ensino tem sido um processo cada vez mais visível na sociedade brasileira, porém, em se tratando do ensino superior, essa realidade ainda pouco percebida quando analisada a partir das categorias acesso e permanência. Em se tratando da pessoa com deficiência visual, por exemplo, a inclusão é ainda mais dificultada em virtude da acessibilidade arquitetônica que, em geral, não existe. Assim, tendo como base o direito da pessoa com deficiência visual à sua livre circulação nos espaços de sociabilidade, este estudo buscou investigar a (in)acessibilidade arquitetônica presente em um campus universitário multi-institucional localizado no município de Iguatu/CE, que possui dois alunos cegos matriculados em um dos seus cursos. Assim, configurando-se como um estudo descritivo, realizou-se uma visitação à referida instituição a fim de verificar aspectos da sua arquitetura que estão ou não em conformidade com a NBR 9050/ABNT que versa sobre a acessibilidade para pessoas com deficiência visual (cegos e baixa visão). A partir de registros fotográficos e de anotações em um diário de campo, verificou-se que, embora a instituição tenha sido inaugurada recentemente, não há nenhuma acessibilidade arquitetônica em seus espaços, revelando sua dissonância com a referida legislação, culminando em um conjunto de barreiras arquitetônicas que dificultam e/ou impedem a permanência e livre circulação de pessoas com deficiência visual em seus espaços.
Understanding the thermal durability of wood-based composites (WBCs) using crack propagation fracture toughness
Authors: Mahapatra Sweta , Sinha Arijit , Nairn John A.
Published: May 2021

Wood-based composites (WBCs) are engineered wood products that are commonly used in the building and furniture industries. Most research on their durability has relied on internal bond testing, bending strength properties, or damage observations. An alternative property with potentially more information is fracture toughness. Here, fracture toughness was continuously measured during crack propagation for three different composites—oriented strand board (OSB), medium density fiberboard (MDF), and particleboard (PB). The resulting plots for fracture toughness as a function of crack growth are known as the material’s R curve. To assess the role of temperature on WBC durability, R curve experiments were repeated at 10 different temperatures from 20 to 200 °C. Trends in experimental results could be described by a trilinear model. OSB and MDF toughness initially increased with temperature and then decreased above 80 °C. The toughness of PB, which was made with a different resin, remained constant or decreased slightly until decreasing faster above 140 °C. Both the resin type and composite structure affected the results.
On the existence of posterior mean for Bayesian logistic regression
Authors: Pham Huong T. T. , Pham Hoa
Published: May 2021

Existence conditions for posterior mean of Bayesian logistic regression
depend on both chosen prior distributions and a likelihood function.
In logistic regression, different patterns of data points can lead
to finite maximum likelihood estimates (MLE) or infinite MLE of the
regression coefficients. Albert and Anderson
[On the existence of maximum likelihood estimates in logistic regression models,
Biometrika 71 1984, 1, 1–10]
gave definitions of different types of data points, which are complete separation, quasicomplete
separation and overlap. Conditions for the existence of the MLE for
logistic regression models were proposed under different types of
data points. Based on these conditions, we propose the necessary and
sufficient conditions for the existence of posterior mean under different
choices of prior distributions. In this paper, a general wide class
of priors, which are informative priors and non-informative priors
having proper distributions and improper distributions, are considered
for the existence of posterior mean. In addition, necessary and sufficient
conditions for the existence of posterior mean for an individual coefficient is also proposed.

Representations of masculinity in two stories by Carlos Casares
Authors: Carballal Ana
Published: May 2021

The study of masculinity and its representation is especially fascinating in Spanish and Galician literature of the mid-20th century. In the two stories to be analyzed in this essay, “O xogo da Guerra” (“The War Game”) and “Agarda longa ao sol” (“Long Wait under the Sun”) — both written by Carlos Casares (Ourense 1941-Nigrán, Pontevedra 2002)—the versions of masculinity displayed by male characters can be considered as denunciations of the model that Franco wished to impose: made in his image, disciplined, cold, and violent. Manhood in Casares is characterized by an ability to accept nonconformity and to assume a reality that conflicts with masculine epistemology as it is known. The new man is ready to absorb a new reality and free a society consumed by hatred, pushing it towards democracy and understanding. Galicia and its people are the main protagonists of these transformations.

Indigenous Remains, Colonialism and Ethical Dilemmas
Authors: De la Rosa A. José Farrujia
Published: May 2021

This paper examines how Eurocentric and colonial assumptions that until recently guided the handling of human remains in archaeology and museography are now regarded as problematic, focusing on the situation on the Canary Islands, which has recently passed new legislation (Canary Islands Law 11/2019) on cultural heritage that includes an amendment on human remains. Museums in the Canary Islands continue to display Indigenous bones and embalmed bodies in glass cases, and bone material is even used in contemporary art installations. The paper examines the new law in relation to the ICOM Code of Ethics for Museums as well as other ethical and legal frameworks that address the issue of human remains. We also draw attention to the role of politics, social scientists and society in this debate.
Hermenêutica bíblica: prolongamentos de sentidos a partir da modernidade.
Authors: Santos Suely Xavier dos
Published: May 2021

O estudo da Bíblia passa por diversas fases até chegar ao que se vê hoje numa relação de busca de sentidos e de releituras que coloquem a narrativa em planos diversificados de leitura, para isso é necessário revisitar os métodos de interpretação e, ao mesmo tempo, ampliar o diálogo com as ciências da modernidade, as quais colocamos em evidência, principalmente, aquelas que superaram o positivismo metodológico. É necessário fazer o exercício constante de atualização no sentido de colocar as discussões hermenêuticas em evidência no presente a partir das propostas já colocadas como forma de leitura e interpretação da Bíblia. E é sobre isto que este artigo pretende versar, a saber, apresentar os prolongamentos de sentidos na modernidade a partir das diversas discussões atuais a respeito da leitura e interpretação da Bíblia.
João 21: indícios para a reconstituição de movimentos do Cristianismo Primitivo
Authors: Garcia Paulo Roberto
Published: May 2021

O Capítulo 21 do Evangelho de João, reconhecido como um apêndice do Evangelho, é geralmente entendido como a explicação da morte do discípulo amado. Essa morte trouxe um trauma para a comunidade que esperava a volta de Jesus antes da morte dele. Esse capítulo, contudo, mais do que explicar a morte de João, o discípulo amado, nos apresenta indícios que nos permitem reconstituir processos importantes na formação do cristianismo primitivo, inclusive a aproximação das comunidades que se reuniam debaixo da autoridade de João (que chamamos de comunidades de memória joanina) das comunidades que se reuniam debaixo da autoridade de Pedro (comunidades de memória petrina. O capítulo 21 apresenta uma aproximação da tradição joanina das tradições sinóticas, sua releitura e a constituição de bases para que os cristãos e as cristãs joaninos passassem a aceitar a liderança petrina e integrarem o cristianismo de memória petrina.

NOS ENTREMEIOS DA PRESENCIALIDADE E DA VIRTUALIDADE
Authors: Novaes Elis
Published: May 2021

Este artigo objetiva lançar luz sobre o modus operandi da educação a distância e, especificamente, sobre as possibilidades de personalização e individualização do ensino através da implantação e da gestão de estratégias ativas na oferta da educação híbrida. Esta pesquisa foi concebida como uma pesquisa de campo, realizada em uma instituição de ensino superior, no período de fevereiro a dezembro de 2019. Como proposta metodológica, nos valemos de um estudo interventivo, apoiado nas pistas do método cartográfico, que nos permitiu compreender como a implantação planejada da educação híbrida pode ser capaz de impulsionar e promover uma redução do distanciamento transacional através de estratégias de integração e harmonização dos ambientes virtual e presencial. A perspectiva mecânica de aprendizagem, baseada em paradigmas instrucionistas, cuja base se encontra na compreensão do mero sombreamento da educação presencial tradicional com a educação a distância clássica, ainda é uma prática em muitas instituições de ensino no Brasil e no mundo. Isso acontece em desalinhamento com a adequada formação para viver e trabalhar em uma era pós-industrial, baseada na economia do conhecimento, quando aspectos cognitivos mais complexos devem ser considerados.

Published: May 2021

To test the effect of the amino acid isoleucine on the malaria parasite Intraerythrocytic Development Cycle (IDC) we compared parasite developmental progression in cultures with and without isoleucine (50 mg/L), as well as after different durations (7, 14, 18 hours) of isoleucine starvation. We set up N = 112 cultures (from 8 mice) so that for each time point within each treatment, an independent culture was sampled, avoiding any bias associated with repeat-sampling individual cultures. We used eight-week-old wild type female mice, MF1 strain, and bled mice when parasites were late rings/ early trophozoites. Approximately 1 ml of blood was collected from each mouse which was then split equally across cultures in all 5 treatment groups. Infected blood was washed twice with buffered RPMI containing no amino acids, before being reconstituted in the RPMI medium corresponding to each treatment (containing isoleucine, or not). Parasites were cultured in 96-well round bottom plates with total culture volumes of 200-250 µl, at ~3% haematocrit. The culture plates were placed inside a gas chamber which was gassed upon closing with 88% nitrogen 7% carbon dioxide and 5% oxygen, and then placed inside a 37°C incubator. The culture medium was custom made RPMI from Cell Culture Technologies, Switzerland (http://www.cellculture.com).
Dynamics of a Wheeled Cart Driven by a Savonius Rotor
Authors: Holub A. P. , Zubkov A. F. , Masterova A. A. , Selyutskiy Y. D.
Published: May 2021

Savonius rotor is one of relatively wide-spread type of wind turbines. The rotation rate of this rotor is considerably lower than that of horizontal axis wind turbines and Darrieus wind turbines. However, it starts rotating at small wind speeds, doesn’t require any additional devices to ensure its re-orientation in case of change of the wind direction, and generates a rather large torque. Therefore, it is suitable for use as a drive in different mechanical and electromechanical systems. In the present paper, dynamics of rectilinear motion of a wheeled cart is studied, which is driven by Savonius rotor installed on it. It is assumed that the wind makes a certain constant angle with the line, along which the cart moves. The aerodynamic load upon the rotor is described with an empirical model, in the context of which the aerodynamic characteristics (aerodynamic torque, drag and lateral force coefficients) are represented as Fourier series with respect to the rotor revolution angle, the coefficients of the series being functions of the rotor tip speed ratio (dimensionless angular speed). Experiments were performed in the subsonic wind tunnel of the Institute of Mechanics of Lomonosov Moscow State University intended to measure aerodynamic characteristics of the rotor at different wind speeds and rotor angular speeds. Based on experimental data, functions were proposed that approximately describe the dependence of the above mentioned coefficients upon the tip speed ratio. The obtained dependences were used for analysis of dynamics of the cart driven by the Savonius rotor. The equations of motion are averaged with respect to the angle of revolution of rotor. Steady solutions of this averaged system are studied. It is shown that, for certain values of parameters, there exist two attracting steady motions corresponding to different directions of the cart velocity. Cart dynamics in the context of the full system of equations of motion is compared with its dynamics in the context of the averaged system.

PROFESSIONAL CONSULTING, PLANNING AND DESIGN OF REGIONAL DEVELOPMENT IN THE FACE OF INCREASING UNCERTAINTIES AND RISKS
Authors: Fomenko G. A. , Fomenko M. A.
Published: May 2021

The article reveals features of the ongoing transformations in the field of consulting, planning and design in the field of regional development in the face of increasing uncertainties and risks, primarily related to climate change and biodiversity loss. It shows that the very basis of such work is significantly changing, as the world-system becomes more complex, during the transition from the concept of an “empty” world to a “full” world. This change includes increasing emphasis on ensuring the resilience of human-dominated ecosystems, a change in decision-making, using behavioral a “responsible” human model that best meets the needs of inclusive sustainable development.

The authors define features of consulting, planning and design of regional development in the face of increasing uncertainties and risks, as a special type of thinking activity, in a situation of approaching radical uncertainty. The article shows the necessity of supplementing natural science approaches with the tools and practices of post-normal science and the narrative theory of beliefs, as well as the ideas of K. Friston, implemented within his dynamic causal model.

Such an approach is based on a systematic approach to decision-making in regional development and pays special attention to the adaptation of individuals and communities to high risks and uncertainties, primarily climatic and natural. It helps to better reflect the diversity of geographical conditions, to clarify the range of effective solutions for sustainable development of regions and increase the long-term resilience of business.

Published: May 2021

Purpose: The effect of nutritional status on in-hospital mortality in patients with coronavirus disease 2019 (COVID-19) is unclear. We aimed to analyze the relationship between nutritional status score (CONUT) and prognostic nutritional index (PNI) and in-hospital mortality in COVID-19 infection.

Materials and Methods: We included 187 patients with COVID-19 between 11 March-10 May 2020. The CONUT and PNI scores were calculated using the laboratory results. The groups were divided into survival and in-hospital mortality

Results: The mean age of the patients was 66.2±15.8 years (55.3% male). The mortality rate was 20.8% (n=39). The median PNI scores was significantly lower and the median CONUT score was significantly higher in the mortality group. Multivariate regression analysis showed that PNI and CONUT were independent predictors of mortality. ROC curve analyses showed that CONUT had a better performance than PNI to predict in-hospital mortality.

Conclusion: In COVID-19 patients, CONUT and PNI scores were independently associated with in-hospital mortality, with CONUT presenting a better performance than PNI.

Purpose: This study aimed to evaluate the predictability of survival in patients with glioblastoma using a machine learning (ML) model developed with tissue analysis features obtained through preoperative post-contrast T1-weighted images(T1WI).

Materials and Methods: The radiomic features of tumors were obtained from postcontrast T1WI of 60 glioblastoma patients. Radiomic properties, density, shape, and textural properties obtained from six matrices were included in the analysis. The patients' three- and six-month survival rates were recorded. Five different ML algorithms were applied to create predictive models [random forest, neural network, linear discriminant analysis(LDA), stochastic gradient descent (SGD), and support vector machine(SMV)].

Results: The mean survival time of the patients was 295.4 days, and the median value was 211.5 (17-1357) days. Among the models developed for three- and six-month survival prediction, the highest success was obtained from the LDA algorithm, in which the AUC values were calculated as 0.88 and 0.78, respectively.

Conclusion: Using ML techniques, the success of predicting imaging-based patient survival was very high. With the development and widespread adoption of these techniques, ML models will be useful in deciding on treatment according to survival prediction in glioblastoma.

Gereç ve Yöntem: Çalışmaya düzenli kontrole gelen 97 ötimik BB tip 1 hasta alınmıştır. Katılımcılara Sosyodemografi Veri Formu, Bilinçli Farkındalık Ölçeği (BFÖ), Morisky İlaç Uyum Ölçeği (MUÖ), İç görü Değerlendirme Ölçeği (İDÖ) uygulanmıştır.

Bulgular: Tedavi uyumu yüksek ve orta düzeyde olan hastalarda, düşük düzeyde olanlara göre BF düzeyleri yüksek bulunmuştur. BF düzeyi ile iç görü düzeyi ve atak sıklıkları arasında istatistiksel olarak anlamlı ilişki bulunmamıştır. Regresyon analizlerinde ise hastalarda tedaviye uyum düzeylerinin son iki yıldaki manik/hipomanik atak sıklığı ile anlamlı ilişkisinin olduğu belirlenmiştir.

Sonuç: BB hastalarında ötimik dönemde var olan BF düzeylerinin atak sıklığı üzerinde etkisinin olmadığı bulunmuştur. BF düzeyleri yüksek olan BB hastalarında tedavi uyum düzeylerinin yüksek olduğu ve BF’nin tedaviye uyumu artırıcı bir etkisinin olduğu belirlenmiştir. BF tedavi uyumunu artırmakta, tedavi uyumu yüksek hastalarda ise manik/hipomanik atak sıklığı azalmaktadır..

O zebrafish ou paulistinha (Danio rerio) são cada vez mais utilizados em pesquisas científicas incluindo a pesquisa básica e aplicada nas áreas de biomedicina, toxicologia, ciências ambientais e aquicultura. No Brasil, os biotérios automatizados são escassos, têm custo oneroso e para fazer uso do modelo animal são necessárias adaptações para criação e manutenção da espécie. Deve existir a compreensão de que as adaptações devem respeitar os padrões de qualidade, implicando na diminuição de mortalidade e doenças nos aquários de manutenção. O objetivo desta revisão de literatura é apresentar as recomendações de protocolo de manutenção do zebrafish, em condições de laboratório, sem o uso de biotério automatizado. Apesar da gama de informações e diferentes métodos de manutenção encontrados para a espécie, fica claro que em condições de laboratório se deve manter o animal nas melhores condições, possibilitando qualidade no desenvolvimento e na reprodução para realizar experimentos com confiabilidade de execução.

Abstract

The use of Zebrafish or paulistinha (Danio rerio) has increased considerably in basic and applied scientific research as biomedicine, toxicology, environmental sciences and aquaculture. In Brazil, automated experimental animal facilities are scarce and costly. To make use of this animal model, adaptations are required for creation and maintenance. These changes must respect quality standards, providing mortality and disease reduction in aquariums maintenance. The literature review aim is to synthesize recommendations for the zebrafish maintenance protocol in laboratory conditions without the automated experimental animal facility. Despite the information range and different maintenance methods found for the species, it is clear that under laboratory conditions, the animal must be kept in the best conditions, enabling development and reproduction quality to be used in experiments with reliable execution.

The research was carried out in the alpaca production unit of the Tomas Peasant Community, of the Lima Region, with the aim of identifying the floristic component of the pasture of a wetland area in the dry season of the year and the species that were most consumed by alpacas. Previously, the floristic inventory of 5 hectares of pasture was carried out and 10 mother alpacas and 10 tuis alpacas were assigned. During the study period, stool samples were taken to evaluate the diet by the microhistological method. The chemical components of the six main species of grasses most consumed were analyzed. In the initial inventory 36 species were found, of which the most consumed were 10 that made up approximately 80% of the diet. Chemical analysis shows a crude fiber content in a range between 66,23 to 77,24%, crude protein between 2.49 to 5,21% and vitamin A between 0,08 to 0,37 mg / 100g. The contribution of the present is to identify the species of pasture most consumed by alpacas tuis and mothers, in order to take care in their conservation.

The results of assessing the possibilities of using of biomass of fallen leaves as a filler of composite polymer materials with a polyvinyl chloride polymer matrix are presented. Samples of composites with biomass of fallen leaves we obtained by extrusion and hot pressing method. The dependences of their physical and mechanical properties on the content of the filler were determined. These de-pendencies are given in the form of polynomial of the second degree. In terms of most physical and mechanical properties (with the exception of impact strength) composites with biomass of fallen leaves are superior to samples of wood-polymer composites with wood flour with a similar degree of filling. Made of a comparison of the effectiveness of three different plasticizers: dimethyl phthalate, dibutyl phthalate and dioctyl therephthalate. The most promising is the use of dibutyl phthalate as a plasticizer. It has been shown that the biomass of fallen leaves is an effective replacement for wood flour in the production of wood-polymer composite materials with a s fr.

An assessment of the efficiency and safety of the formaldehyde decontamination process containing solid waste of wood-chip boards by method of medium-temperature dry pyrolysis at the installation developed by the authors was evaluated. Sawdust of chip boards and coke ash residue after their pyrolysis were subjected to biological examination. The test objects were Daphnia magna Straus, algae Scenedesmus quadricauda and luminescent bacteria. It was revealed that pyrolysis of these wastes at the proposed plant will reduce the load on the hydrosphere and reduce the ratio of dilution of water extracts by more than half. Analysis of the composition of pyrolysis gases showed that the mass concentration of nitrogen oxides and carbon in the air of the working zone does not exceed the MPC of the working zone and MPC of settlements. The conclusion on environmental safety of the process of pyrolysis of formaldehyde-containing solid wastes at the proposed installation is made.

Published: May 2021

A embalagem representa um papel essencial na conservação de alimentos, pode ser constituída de diversos materiais que flexibilizam sua aplicação e não deve possuir elementos migrantes que alterem a qualidade do produto. Diante disso, foi avaliado o potencial de migração e biodegradação de resina aplicada à embalagem celulósica destinada ao acondicionamento de bebidas refrigeradas, alternativa biodegradável à embalagem de poliestireno empregada usualmente. A migração foi mensurada por meio da quantificação gravimétrica do resíduo após contato com simulantes, água, ácido acético 3% (v/v), etanol 10% (v/v), e n-heptano. A biodegradação foi avaliada mediante verificação da perda de massa. A embalagem mostrou-se segura em contato com alimentos gordurosos em todos os ensaios, com produtos alcóolicos a 20°C até 48h, e 40°C por 2h e com água a 40°C até 24h e 65°C por 2h. O revestimento interferiu significativamente (p>0,05) na perda de massa, sendo que no 107º dia a embalagem revestida apresentou 38% de massa residual e a não-revestida 31%.
¿Es posible hoy una sociedad sin universidad? Una mirada histórica a la universidad desde la época de la pandemia de COVID-19
Authors: Maya Gualdrón Ramón Arturo
Published: May 2021

En la historia de la universidad es fácil reconocer los aportes que esta ha hecho a la sociedad. Cuando hablamos de universidad, estamos hablando de una institución que tiene unos componentes muy específicos, sin los cuales es imposible su existencia. En este texto queremos analizar esos componentes y, precisamente, a partir de la historia de la universidad. En zonas boscosas e incomunicadas de la Europa medieval, pobladas de múltiples amenazas de diversa naturaleza, unas materiales, como ladrones y asesinos, y otras inmateriales, espíritus y demonios, los conventos guardaban con un especial celo esos viejos libros que el azar había permitido atesorar y que eran empleados para convocar a la comunidad de monjes, al caer de la tarde, para que escucharan en la lectura en voz alta los pensamientos de antiguos maestros mientras consumían la magra cena; aquellos religiosos se esforzaban por memorizarlos con la convicción de entrar así en relación con la sabiduría que venía de lejanos mundos. Esta dinámica se reconocía como el magister dixit, fundamento sólido y rico del conocimiento en el que comenzará su existencia la universidad.
