A.A. Fet's essays "From the Village" and Pavel Medvedev's article "Dreams and Reality": on the history of the controversy
Authors: Tselikova Ekaterina Viktorovna
Published: November 2020

The article analyzes in detail the views on the purpose of art and science of representatives of the aesthetic school and the school of democratic poetry of Russian literature of the XIX century. As a material for analysis, A.A. Fet's essays "From the Village" are used, in which the poet's view of the role and tasks of poetry, science and art in general is presented in detail. The opinion of the opponents вЂ“ the democratic school вЂ“ is presented by the example of the article "Dreams and reality" by the author of the satirical magazine "Iskra" Pavel Medvedev. The article examines in detail the polemical dialogue between the two schools, analyzes and compares the arguments of its representatives. The article discusses various mechanisms that allow the use of aesthetic beliefs as a basis for the formation of a parodically distorted personality and as a way to expose true views. P.A. Medvedev's cycle "Dreams and Reality", combining the features of satirical parody and satire itself, was created as a tool capable of discrediting A.A. Fet's journalistic speeches in essays "From the Village" and thus exposing not only his aesthetic, but also his socio-political position, the beliefs of a reactionary and a serf. The parodist achieved this effect exclusively through interpretation and commenting on the statements of A.A. Fet himself.

The scientific works of scholars and experts dedicated to conceptology, intercultural communication, and linguistics became the foundation for this research. The author analyzes bibliography, presents various approaches towards conceptology, formulates main conclusions of recent research on the indicated problematic, as well as provides specific examples. Research of the concepts presented in different linguistic worldviews, including Russian linguistic paradigm of the world, is first and foremost substantiated by the importance of intercultural communication in the current context. The relevance of this topic is defined by the significance of studying the dialogue of cultures, language, culture and mentality. The selected topic is of interest to the philosophers, linguists, culturologists and foreign language pedagogues. In anthropological linguistics, cognitive linguistics, psycholinguistics, sociolinguistics, ethnolinguistics, linguoculturology and other fields, the subject of research is the concept of the dialogue of cultures along with interaction between language, culture and mentality. The development of Russian relations on international arena over the past decade led to active cooperation in the area of education, economy, trade and tourism. Therefore, there is an urgent need for studying communication in the situation of interaction between the representatives of Russian and foreign cultures from the perspective of teaching languages as a means of intercultural communication. The need to study communication is justified by different communication behavior in Russia and other countries in the cultural aspect. Insufficient understanding of the language of communication can result in communication failures and even initiate cross-cultural conflict. In the following paragraphs of this article, the author gives detailed attention to specificity of the concept in the linguistic worldviews.

The influence of thermal after-treatment on the adhesion of 3D prints on textile fabrics
Authors: Ehrmann Andrea , Görmer Daniel , Störmer Jannik
Published: November 2020

3D printing belongs to the emerging technologies of our time. While it enables producing new structures and makes individualized products affordable, 3D printed objects still suffer from low production speed and often insufficient mechanical properties. Both these problems can be tackled by combining 3D printing with substrates prepared by conventional technologies, e.g. textile fabrics. In this case, the adhesion between both partners is most challenging and defines for which possible applications such composites are suitable. Here, we report on a new approach to increase the adhesion between 3D printed materials and warp knitted fabrics, showing that in some cases a thermal after-treatment, in the simplest case performed by ironing, is able to significantly increase the adhesion between both materials.

The optimization of compounds with multiple targets in the drug discovery cycle is a difficult multidimensional problem. Here, we present a systematic, multidisciplinary approach to the development of selective anti-parasitic compounds. Efficient microwave-assisted synthesis of pteridines along with iterations of crystallographic structure determination were used to validate computational docking predictions and support derivation of a structure-activity relationship for multitarget inhibition. This approach yielded compounds showing picomolar inhibition of T. brucei pteridine reductase 1 (PTR1), nanomolar inhibition of L. major PTR1, along with selective submicromolar inhibition of parasitic dihydrofolate reductase (DHFR). Moreover, by combining design for polypharmacology with a property-based on-parasite optimization, we found three compounds that exhibited micromolar EC50 values against T. brucei brucei, whilst retaining their target inhibition. Our results provide a basis for the further development of pteridine-based compounds and we expect our multitarget approach to be generally applicable to the design and optimization of anti-infective agents.

Published: November 2020

Currently, there are limited reports regarding investigation of the biological properties of polyetheretherketone (PEEK) coated with titanium (Ti) and hydroxyapatite (HA) in human. The objective of this study is to evaluate the in vivo response of the PEEK cages coated with Ti and HA versus uncoated PEEK cages after anterior cervical discectomy and fusion (ACDF) in patients with single-level cervical degenerative disc disease (CDDD). Twenty-four patients with PEEK cages coated with Ti and HA (PEEK/Ti/HA group) were matched one-to-one with patients with uncoated PEEK cages (PEEK group) based on age, gender, and operative segment. All patients had been followed up for more than 2 years. Radiological assessments included intervertebral height (IH), C2-7 angle(C2-7a), segmental alignment (SA), and fusion rate. Clinical parameters included Visual Analogue Scale (VAS) and Japanese Orthopedic Association (JOA) scores. There was no statistical difference in SA, IH, and C2-7a between the two groups before and after surgery and all these parameters were restored postoperatively. The fusion rate of PEEK/Ti/HA group was significantly higher than PEEK group at 3-month post-operation (87.5% vs. 62.5%). At the last follow-up, the fusion rate of the both groups achieved 100%. The VAS and JOA scores were comparable between two groups and improved postoperatively. In conclusion, in patients with single-level ACDF, PEEK cage coated with Ti and HA provided a higher fusion rate than uncoated PEEK cage at 3-month post-operation, while both of the two cages could achieve solid osseous fusion at the last follow up. Compared with the uncoated PEEK cage, PEEK/Ti/HA cage yielded similar favorable segmental and overall cervical lordosis, IH, and clinical outcomes after the surgery.
Heterogeneous Intramolecular Electric Field as a Descriptor of Diels-Alder Reactivity
Authors: Hennefarth Matthew , Alexandrova Anastassia N.
Published: November 2020

External electric fields have proven to be an effective tool in catalysis, on par with pressure and temperature, affecting the thermodynamics and kinetics of a reaction. However, fields in molecules are complicated heterogeneous vector objects, and there is no universal recipe for grasping the exact features of these fields that implicate reactivity. Herein, we demonstrate that topological features of the heterogeneous electric field within the reactant state, as well as of the quantum mechanical electron density – a scalar reporter on the field experienced by the system – can be identified as rigorous descriptors of the reactivity to follow. We scrutinize specifically the Diels-Alder reaction. Its 3-D nature and the lack of a singular directionality of charge movement upon barrier crossing makes the effect of the electric field not obvious. We show that the electric field topology around the dienophile double bond, and the associated changes in the topology of the electron density in this bond are predictors of the reaction barrier. They are also the metrics by which to rationalize and predict how the external field would inhibit or enhance the reaction. The findings pave the way toward designing external fields for catalysis, as well as reading the reactivity without an explicit mechanistic interrogation, for a variety of reactions.

Published: November 2020

Lacking rapid and reliable microbial detection and sensing platforms, insufficient understanding towards microbial behaviors may generated or delayed precautions could be made, which greatly threatens human life and increase heavy financial burdens to the society. In this contribution, a dual-aggregation-induced emission luminogen (AIEgen) system is successfully developed for microbial imaging and metabolic status sensing. This system consists of two AIEgens (DCQA and TPE-2BA) that bear positive charged groups or boric acid groups, providing universal microbial staining ability and specific affinity to dead microbes, respectively. On the basis of the distinctive fluorescence response produced by the diverse interaction of AIEgens with live or dead microbes, this dual-AIEgen system can detect all the microbe and identify their viabilities. Furthermore, the morphology and metabolic status of a sessile biofilm can also be imaged and monitored. The system exhibits rapid labelling, suitable for various microbes, and good biocompatibilities.
Thionation Induces Efficient Generation of Excited Triplet State and Singlet Oxygen: Heavy Atom-Free BODIPY Photosensitizers Based on S1(n,π*) State
Authors: Hu Wenbin , Zhang XIan-Fu , Liu Mingyu
Published: November 2020

The attachement of SR (R is alkyl or phenyl) makes BODIPY efficiently generate excited triplet state (T1) and singlet oxygen with quantum yield up to 0.82 (compared to 0.10 of parent BODIPY). This affords an efficient method to synthesize heavy atom free photosensitizers. This efficient T1 formation is because SR presence leads to a new excited state S1(n,pi*) with an energy smaller but close to the usual S1(pi,pi*) state.
On the Use of Catalysis to Bias Reaction Pathways in out Of-Equilibrium Systems
Authors: van der Helm Michelle , de Beun Tuanke , Eelkema Rienk
Published: November 2020

Catalysis is an essential function in living systems and provides a way to control complex reaction networks. In natural out-of-equilibrium chemical reaction networks (CRNs) driven by the consumption of chemical fuels, enzymes provide catalytic control over pathway kinetics, giving rise to complex functions. Catalytic regulation of man‑made fuel‑driven systems is far less common and mostly deals with enzyme catalysis instead of synthetic catalysts. Here, we show via simulations, illustrated by literature examples, how any catalyst can be incorporated in a non-equilibrium CRN and what their effect is on the behavior of the system. Alteration of the catalysts’ concentrations in batch and flow gives rise to responses in product yield, lifetime and steady states. In-situ up or downregulation of catalysts’ levels temporarily changes the product steady state, whereas feedback elements can give unusual concentration profiles as a function of time and self-regulation in a CRN. We show that simulations can be highly effective in predicting CRN behavior and mapping parameter space, for complex processes that can proceed counterintuitively. In the future, shifting the focus from enzyme catalysis towards small molecule and metal catalysis in out-of-equilibrium systems can provide us with new reaction networks and enhance their application potential in synthetic materials, overall advancing the design of man‑made responsive and interactive systems.
Hopping Conductance in Molecular Wires Exhibits a Large HeavyAtom Kinetic Isotope Effect
Authors: nguyen Quyen , Frisbie C. Daniel
Published: November 2020

We report a large kinetic isotope effect (KIE) for intramolecular charge transport through pi-conjugated oligophenylene imine (OPI) molecules > 4 nm in length connected to Au electrodes. 13C and 15N heavy-atom substitution on the imine bonds produces a normalized conductance KIE of ~2.7 per labeled atom in OPI wires, far larger than typical heavy-atom KIEs reported for chemical reactions. In contrast, isotopic labeling of the imine bonds for short OPI wires < 4 nm does not produce a conductance KIE, consistent with a direct tunneling mechanism expected for short molecules. Temperature dependent measurements on a long (> 4 nm) 15N-substituted OPI wire and its unlabeled isotopologue reveal that conductance is activated. The conductance results for long wires are thus consistent with multi-step polaron transport and we propose that the exceptionally large conductance KIEs imply a thermally-assisted, through-barrier polaron tunneling mechanism. In general, the observation of large heavy-atom conductance KIEs opens up considerable opportunities for exploring microscopic conduction mechanisms in pi-conjugated molecules.

Published: November 2020

Repurposing of the existing medications has become the mainstream focus of anti-COVID-19 drug discovery as it offers rapid and cost-effective solutions for therapeutic development. However, there is still a great deal to enhance efficacy of repurposing therapeutic options through combination therapy, in which promising drugs with varying mechanisms of action are administered together. Nonetheless, our ability to identify and validate effective combinations is limited due to the huge number of possible drug pairs. Yet, there is no available resource which can systematically guide to identify or choose the effective individual drugs or best possible synergistic drug combinations for the treatment of SARS-CoV-2 infection. To address this resource gap, we developed a web-based platform that displays the network-based mechanism of action of drug combinations, thus simultaneously giving a visual of the cellular interactome involved in the mode of action of the chosen drugs. The platform allows the freedom to choose two or more drug combinations and provides the options to investigate network-based efficacy of drug combinations and understand the similarity score, primary indications, and contraindications of using these drugs combinations. In a nutshell, the platform (accessible via: http://vafaeelab.com/COVID19_repositioning.html) is of the first of its type which provides a systematic approach for pre-clinical investigation of combination therapy for treating COVID-19 on the fingertips of the clinicians or researchers.

INTRODUCTION: Insomnia is a risk factor for various physical and mental disorders as well can affect the academic performance of a student(s). AIM: To assess the prevalence of insomnia among university going students (medical, dental and nursing streams) in the South Asian continent during the lockdown due to the COVID-19 pandemicMATERIALS AND METHOD: The present study was conducted amongst 743 medical, dental and nursing undergraduate students residing in South Asia using convenience sampling. Data was collected using a pre-tested and pre-validated questionnaire [the Athens Insomnia Scale (AIS)] using google forms and had a total of 8 questions (score range 0-3) . Final scores (the individual AIS score) were obtained by adding the scores for each question (range 0 -24). The higher the score was, the worse was the sleep quality; students with score of ≥ 6 were considered insomniac. Data Analysis was done using SPSS version 21.012 by using the independent samples t-test, and multiple logistic regression.RESULTS: A total of 921 entries were recorded, out of which 743 were complete and hence, were included in the study (response rate: 80.7%). Insomnia was reported in 421 (56.7%) students, out of which, the highest was seen among dental (62.7%), followed by medical (59.8%) and nursing (45.3%) undergraduates. The highest range of AIS was observed among females (6-22) and dental students (6-21). Gender differences revealed a significant association among females in both range obtained (t-test) (p=0.03) as well as the multiple linear regression analyzing insomnia in relation to gender (p=0.03).CONCLUSION: There is a need to regularly assess insomnia among students and to take preventive measures incase of high prevalence is found among them, especially while pursuing academics online and from their homes due to the pandemic.
COVID-19 and Retinal Toxicity of Anti-Malarials
Authors: Mohit Bharti
Published: November 2020

The use of chloroquine and hydroxychloroquine in the tough time of COVID-19 has gained much attention. The production and use of these drugs has drastically increased in the past few months. However, it is important to know that retinal toxicity is a very rare side effect of these therapies that can lead to permanent vision loss. The mechanism is however unclear, but this toxicity might depend on the tolerance of the subjects exposed. It is important to choose the appropriate dosage which should be customized as per the patient’s condition, age, body weight and comorbidities. Also, to avoid the occurrence of retinopathy, eye examination and ophthalmic screening for the patients being administered these drugs should be done. This review discusses the risk determinants, the clinical presentations and screening techniques of retinal toxicity.

The study was carried out in-situ using a Radalert 100 nuclear radiation monitor and a geographical positioning system (GPS). Five facilities were investigated at the rig site which included the rig site host community as well as the camp site for the oil workers at Ekapkamreh town. Ten 10 sampling locations were evaluated at a total of 60 study points. The values obtained range between 0.115±0.018 (µSv/hr) and 0.299±0.040 (µSv/hr) for the rig site environment, 0.111±0.006 (µSv/hr) and 0.337±0.031 (µSv/hr) for field logistic base (offices and workshops), 0.114±0.011 (µSv/hr) and 0.312±0.021 (µSv/hr) for components of the mud circulation section. Also, the radiological concentration of the Chemical Store ranged between 0.126±0.019 (µSv/hr) and 1.181±0.104 (µSv/hr), while the radiological values obtained from other facilities within the rig site ranged from 0.155±0.026 (µSv/hr) and 0.249±0.026 (µSv/hr). Radiation readings obtained for soil ranged from 0.149±0.05 (µSv/hr) to 0.219±0.025 (µSv/hr) and 0.114±0.039 (µSv/hr) to 0.219±0.051 (µSv/hr) respectively at the host community and camp site. Most of the results obtained showed that the general environment of the rig site is slightly above the permissible absorbed dose rate threshold of 0.15(µSv/hr) recommended by the United Nation Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) in 2009. However, the exposure rates exceed the standard background level of 13µR/hr (coequal to 0.13µSv/hr). There is high tendency for the industry workers to be exposed to radiation with time.

A combination of geoelectric and hydrogeologic concept was used in the assessment of groundwater vulnerability in fractured aquifers of Oju and environs. The study area is underlain by the sediments of the Asu River Group, Southern Benue Trough Nigeria. A total of twenty-seven (27) Vertical Electrical Sounding (VES) was carried out within the study area. Geoelectric parameters (layer, resistivity and thickness) of the overlying layers across the study area were determined and used to evaluate the vulnerability of the underlying aquifers. Three charts were compared using geo-electrically derived models; LC (Longitudinal Conductance), GLSI (geoelectric layer susceptibility indexing) and GOD (groundwater occurrence, overlying lithology and depth to the aquifer. Results obtained from LC revealed that the study area fell within the moderate category, GLSI showed that aquifer vulnerability were categorize within negligible to low category and GOD fell within low to moderate category. On the average, groundwater within the study area is considered moderate vulnerable to groundwater contamination.
HYDROGEOPHYSICAL DELINEATION OF PROLIFIC GROUNDWATER AQUIFER AROUND STUDENTS’ HOSTELS IN FUPRE CAMPUS, NIGERIA
Authors: G.I. Alaminiokuma , J.I. Omigie
Published: November 2020

Electrical resistivity survey was conducted around Students’ Hostels in FUPRE to delineate prolific aquifer for potable water to serve the teeming population of staff and students. Five vertical electrical soundings (VES) using Schlumberger electrode configuration with a maximum current electrode spread of 300m were employed for data acquisition. WINRESIST software was employed to execute the iteration and inversion processes of computing resistivities, depths and thicknesses of the various layers and the curve types. Results indicate that the area is characterized by 4 distinct geoelectric layers inferred differently at the VES locations. Two potential groundwater aquifer zones are delineated. The unconfined shallow aquifer zones found at VES 1, 3, 4 and 5 locations have shallow overburden depth ranging between 3.7-19.3m and coarse-grained sand columns with thicknesses ranging between 2.8-17.7m while the confined deep aquifer zone found at VES 2 location coincides with deep overburden layer at a depth of 42.6m and coarse-grained sand column with appreciable thickness of 19.1m. These results suggest that boreholes for sustainable groundwater supply around the Students’ Hostels should be sited at VES 2 location and screened at a depth ≥40.0m. However, aquifers at VES 1, 3, 4 and 5 have potentials for groundwater but are vulnerable to contamination. It is recommenced that electrical resistivity and hydrogeological surveys should be conducted at different locations in FUPRE, before any borehole(s) are drilled, to delineate the appropriate aquifer for potable groundwater supply and to avoid possible contamination.

Cultivating Parental Involvement Through the Lens of Perceived Success and Engagement
Authors:   , McMillon Robin
Published: November 2020

This narrative study used theoretical frameworks of Epstein’s overlapping sphere of influence and parental framework to evaluate parental perceptions of success held by parents and guardians of African American males in a southern California public school and to determine whether those perceptions influenced school- and district-based involvement and engagement. The research investigated how parents defined academic success by their children, which instructional measures used by the site and district were most appreciated, and which forms of engagement they were most likely to utilize throughout the school year. The research secured thoughts and desires of parents who are often overlooked as community members and provided an opportunity to give feedback on the instructional integrity and academic attainment of their children. The research was designed to increase parental involvement by identifying the needs and desires of the participants. In California, district-based funding is predicated on integration of parental involvement, so most schools offer parental engagement activities. However, it is not clear whether parents and guardians of African American males consider those activities as relevant and participate in them. This research addresses achievement disparities between African American males and their grade-level peers in one urban southern California school district and parents’ concepts of student success measures. Therefore, this research has the capacity to build a strategic collaboration among all members of the learning community through their overlapping spheres of influence.

The paper presents the results of research into the technology of soft spring wheat cultivation of the Siberian Alliance variety taking into account the formation of the production process. The experiment was carried out in 2015–2019 in the zone of the northern forest-steppe of Kuznetsk Depression.  The  work  was  done  in  a  long-term  stationary  experiment  of  grain-fallow  crop rotation: fallow (bare, green-manured – rapeseed, melilot) – wheat – peas – barley (pure barley and intercropped with melilot). The following soil tillage systems were studied: deep moldboard (control), deep combined, minimum combined, minimum moldboard. The soil of the experimental plot was characterized as leached medium-textured, medium humus, heavy-loam chernozem. It was revealed that the influence of the preceding crop on the production process of soft spring wheat accounted for 80.4%, the effect of the soil cultivation system was 13.8%. The maximum yield in the experiment was obtained with minimum moldboard system of soil cultivation preceded by rapeseed green-manured fallow (3.34 t/ha) with the lowest cost of grain (4.6 thousand rubles/t) and high profit (30.3 thousand rubles/ha), control indicators being 3.26 t/ha, 9.2 thousand rubles/t and 15.2 thousand rubles/ha, respectively. The following positive effects on the formation of the production process were identified: soil moisture availability, microbiological activity, a decrease in phytosanitary tension, lack of soil compaction at a high content of agronomically valuable particles. Sowing rapeseed on green-manured fallow in the current crop rotation with the application of minimum moldboard tillage system is the most effective method of cultivating soft spring wheat of the Siberian Alliance variety in the northern forest-steppe of Kuznetsk Depression.
Productivity of fodder crop rotations and their impact on the fertility of leached chernozem
Authors: Galeev R. F. , Shashkova O. N.
Published: November 2020

The paper presents the results of the study on the effect of methods for improving a six-field fodder crop rotation on productivity indicators and the content of macroelements available for plants (nitrogen, phosphorus and potassium) in a layer of 0-40 cmof leached chernozem in two rotations. Field studies were carried out in 2008–2019 in the conditions of the forest-steppe zone of Western Siberia. Improvement techniques included introduction of mineral fertilizers, oversowing legumes and oversowing legumes alongside the use of fertilizers. Oversowing legumes in crop rotation fields resulted in the productivity which was not lower than with the application of mineral fertilizer system. When fertilizers were applied, collection of dry matter in the first and second rotation from a unit of crop rotation area increased by 1.6–1.7 times compared to the control, namely 4.20 and

6.30 t/ha, respectively, whereas when legumes were sown in each field, the increase was 1.5–1.8 times (3.97–6.59 t/ha). When both these methods were combined, the yield of dry matter in rotations increased by 1.6–1.8 times (4.32–6.98 t/ha). The alternation of crops in the crop rotation alongside improvement methods during the first two rotations contributed to the 1.7 times increase of nitrate nitrogen in the 0–20 cm layer with the use of mineral fertilizers (3.9 mg/kg of soil), and with legume oversowing – 2.5 times (5.7 mg/kg). The positive effect of crop alternation on the reserves of mobile phosphates in the soil in the control crop rotation was identified. The total amount of mobile phosphates in the experiment was 68 mg/kg in the 0–20 cm layer, and 21 mg/kg in the 20–40 cm layer. By the end of the first rotation, their increase reached 108 and 99 mg/kg, by the end of the second – 239 and 214 mg/kg, respectively. By the end of the second rotation, there was a slight increase in exchangeable potassium in the 0–40 cm layer in the control crop rotation, which was more significant in the 20–40 cm layer – from 97 to 103 mg/kg. In 2018, the mineral fertilization system of cereal crop rotation led to a decrease in exchangeable potassium compared to the control from 116 to 104 mg/kg of soil in the 0–20 cm layer, and from 103 to 91 mg/kg in the 20–40 cm layer. The removal of exchangeable potassium with the yield of cultivated crops due to crop rotation improvement methods exceeded its return with plant residues.

Published: November 2020

O artigo situa-se no escopo mais amplo de uma pesquisa de doutorado, caracterizada como qualitativa, exploratória, pragmática, aplicada, com respaldo na estratégia metodológica da pesquisa-ação, tendo como proposta desenvolver uma metodologia de revisão e atualização de tesauros. Nesse contexto, este trabalho objetiva oferecer contribuições ao modelizador de tesauros e à pesquisa em Biblioteconomia e Ciência da Informação sobre os principais aspectos teóricos aplicáveis à revisão e à atualização de tesauros. Para tanto, contextualiza, a partir da metodologia de revisão narrativa, os contributos teóricos dos principais domínios do conhecimento que fazem interface com a temática pesquisada, a saber: Biblioteconomia, Ciência da Informação), Terminologia e Linguística. Sob esse enfoque, destaca os princípios da Teoria da Classificação Facetada (TCF), de Ranganathan, e da Teoria do Conceito, de Dahlberg. Os aportes teóricos de Dahlberg para a compreensão das características dos conceitos são utilizados na elaboração de definições mais consistentes, as quais são a base para o processo de modelagem conceitual em tesauros, em especial para a criação de relações semânticas. Os aspectos teóricos da Linguística sobre a semântica e a criação de campos semânticos em tesauros também são destacados. Expõem-se, também, as recomendações da norma internacional ISO 25.964-1 (2011) sobre os critérios para elaborar-se relações semânticas hierárquicas, associativas e de equivalência em tesauros. Evidencia-se a aplicabilidade dos princípios teóricos na pesquisa empírica referente à modelagem conceitual de um protótipo de tesauro. As considerações finais revelam a importância dos aportes teóricos para a construção de definições a modelagem conceitual de tesauros.

Authors: Souza José Jullian Gomes de , Cajazeira Paulo Eduardo Silva Lins
Published: November 2020

O presente artigo propõe a ideia de uma cultura do arquivamento audiovisual, visualizada no âmbito acadêmico a partir da produção audiovisual do curso de Jornalismo da Universidade Federal do Cariri. O objetivo é investigar como o armazenamento de documentos audiovisuais como os documentários e as grandes reportagens - desenvolvidos para o trabalho de conclusão de curso - contribui para acesso, uso e recuperação da informação. Além, de criar um sistema de memória audiovisual. A metodologia parte de uma abordagem quanti-qualitativa, a partir de estudo exploratório, visando mapear os lugares de armazenamento digitais. Dessa forma, compreende-se que há a necessidade da implantação de uma cultura do arquivamento audiovisual, para propiciar o armazenamento e o acesso a esses documentos que pertencem à memória social da universidade e da sociedade, uma vez que não são visualizadas as práticas de armazenamento, sobretudo, em ambientes digitais.

O candeeiro se apagou? A universidade brasileira sob fogo cruzado
Authors: Sá Antônio Fernando de Araújo
Published: November 2020

A revista Candeeiro, da Seção Sindical dos Docentes, da Universidade Federal de Sergipe, ao longo do seu período de existência entre 1998 e 2016, desempenhou relevante papel de discussão na comunidade universitária sobre as lutas pela democratização da universidade pública no Brasil. A pluralidade das contribuições dos articulistas revela as disputas políticas e impasses institucionais no enfrentamento às políticas educacionais de corte neoliberal. Apesar de serem publicadas por um “sindicato de intelectuais”, as revistas sindicais docentes não têm tido a devida atenção no campo da história da educação no Brasil, sendo mesmo preteridas. Esse artigo tem por objetivo analisar as implicações da reforma do Estado, de matriz neoliberal no Brasil e na América Latina, tomando como corpus os 22 números publicados pela revista, num recorte dos desdobramentos dessa reforma nas instituições de ensino superior.
