Response surface design for removal of Cr(VI) by hydrogel-supported sulfidated nano zero-valent iron (S-nZVI@H)
Authors: Jing Qi , You Wenhui , Tong Le , Xiao Wenyu , Kang Siyan , Ren Zhongyu
Published: August 2021

In this study, a new sulfidated nanoscale zero-valent iron (S-nZVI) supported on hydrogel (S-nZVI@H) was successfully synthesized for the removal of chromium (Cr) (VI) from groundwater. The surface morphology, dispersion phenomenon and functional groups of novel S-nZVI@H were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy. Box–Behnken design (BBD) optimization technology based on response surface methodology (RSM) is applied to demonstrate the influence of the interaction of S-nZVI@H dose, initial Cr(VI) concentration, contact time, and initial pH with the Cr(VI) removal efficiency. The analysis of variance results (F = 118.73, P < 0.0001, R2 = 0.9916) show that the quadratic polynomial model is significant enough to reflect the close relationship between the experimental and predicted values. The predicted optimum removal conditions are: S-nZVI@H dose 9.46 g/L, initial Cr(VI) concentration 30 mg/L, contact time 40.7 min, and initial pH 5.27, and the S-nZVI@H dose is the key factor affecting the removal of Cr(VI). The predicted value (99.76%) of Cr (VI) removal efficiency is in good agreement with the experimental value (97.75%), which verifies the validity of the quadratic polynomial model. This demonstrates that RSM with appropriate BBD can be utilized to optimize the design of experiments for removal of Cr(VI).

Molecular Docking
Authors: Adamshafi Shaik , Veera Venkatarao , S.V.M. Mohan Rao , V.V.N. Kishore Pilli
Published: August 2021

Introduction:

Progress in the development of triazolyl-oxadiazoles, a bisphosphonate-
700 inhibitor, is still continuing with an outcome of the good scaffold as oxadiazole as well as
triazoles individually for antibacterial activity. Hence, we have proposed a suitable approach for
the synthesis of dual heterocyclic analogues consisting of the therapeutically used non-steroidal anti-
inflammatory drugs in a combined form and evaluated their antibacterial and antifungal activities,
and conducted docking studies.

Methods:

The chemical structures were confirmed by various spectroscopic methods like IR, 1H
NMR, 13C NMR, mass, and elemental analysis. The antibacterial and antifungal activities of these
compounds were screened against Gram-positive and Gram-negative bacteria, and fungal stains, by
the agar well diffusion method. The crystal structure of S. aureus complexed with the active site of
bisphosphonate BPH-700 (2ZCS) was obtained from the Protein Database (PDB,
http://www.rcsb.org). Molecular properties, drug-likeness score, lipophilicity and solubility parameters
were assessed by the Molinspiration and Molsoft software 7f (2-NO2, 5-Ome), 7g (3-Cl, 4-Cl),
7a (2-NO2).

Results:

The synthesised NSAID-triazolyl-oxadiazoles containing 2-nitro-5-methoxy (7f), 3,4-
dichloro (7g) derivatives were found to be highly active antibacterial agents against S. aureus and
E. coli with MIC values of 16 and 19 μg/mL, respectively. 2-nitro-5-methoxy (7f), 4-bromo (7h)
and 2-nitro (7a) derivatives displayed superior antifungal activity against A. niger with MIC values
of 56, 76, and 130 μg/mL, respectively. From molecular docking, NSAID linked to 3,4-dichloro
analogue (7g) revealed stronger binding interaction (ΔG =7.90 Kcal/Mol) with amino acids Asp49
(1.19 A◦), Arg45 (2.17 A◦), Lys17, and Lys46 in the active site of S. aureus complexed with bisphosphonate
Bph-700 (2ZCS). The compounds following the Lipinski ‘Rule of five’ were synthesized
for antimicrobial screening as oral bioavailable drugs/leads. Maximum drug-likeness model score
0.49 and 0.41 was found for compounds 7h and 7b.

Discussion:

An efficient combination of molecular modeling and biological activity provided an insight
into QSAR guidelines that could aid in the further development of these derivatives

Conclusion:

The present work, through simple synthetic approaches, led to the development of
novel hybrids of triazole-oxadiazole pharmacophores that exhibited remarkable biological activities
against different microorganisms. The compounds showed suitable drug-like properties and are
expected to present good bioavailability pro□le.

and antifungal activities were evaluated by diffusion method and the anticancer activities were evaluated
by MTT assay.

Results:

Twenty-seven derivatives have been synthesized in moderate to good yields. A number of
derivatives exhibited potential antibacterial, antifungal and anticancer activities.

Conclusion:

Compounds (1b, 1e and 1g) showed antibacterial activity against Streptococcus faecalis,
MSSA and MRSA with MIC value ranging between 4 to 64 μg/mL. Compound (2g) showed antifungal
activity against Candida albicans (8 μg/mL) and Aspergillus niger (64 μg/mL). Compound
(1o) exhibited high cytotoxic activity against HepG2 cell line (IC50 value 8.6 μM) which is comparable
to the activity of paclitaxel, and is non-toxic on LLC-PK1 normal cell line. The structure activity
relationship and molecular docking study of the synthesized compounds have also been reported.
Demonstrability of Categories: the viae divisivae and their criticisms
Authors: Correia Mário João
Published: August 2021

From an early stage, the Aristotelian list of ten categories was seen with suspicion. Authors discussed not only the scope of the list - expressions, concepts, realities -, but also its alleged arbitrariness. One of the attempts to give an account of the completeness and sufficiency of the Aristotelian categories was inspired by a passage in Aristotle’s Topics: a via divisiva, in a shape of a tree, which covers all the possibilities. At least since Porphyry, several authors applied this scheme to the ten categories. With this work, I intend to present some of the viae divisivae created by 13th century authors, i.e., Robert Kilwardby, Albert the Great and Thomas Aquinas. In a second moment, I will give an account about Duns Scotus’ critique to this kind of procedure. According to Scotus, theviae divisivae do the opposite of what is intended.
The causa sine qua non of Human Cognition for Durand f St. Pourçain
Authors: Silva Maria Clara Pereira e
Published: August 2021

This article aims to analyze the notion of sine qua non cause of the cognitive theory of Durand’ of St. Pourçain Commentary on the Sentences of Peter Lombard [A] and [C]. For Durand, when the intellect acts by a cognitive act, no absolute entity is added to it. The cognition, or thought, is treated by the author as a relative entity, not as something that belongs to the intellect, or as something that is added to it. The sensible species of the material object, spread in the medium, affects the external sensory organs. Therefore, the sensory faculty notices the changes that occurred in the body and is capable of producing a sensation and the cognitive faculty, on its turn, can produce a conception due to the intuition of the changes that happened in the body to which it is associated. Consequently, there is no need to affirm that a cognitive act is the result of an abstractive process. The culmination of his cognitive theory is the rejection of the existence of an agent intellect responsible for abstracting.

Authors: Chiu Ching-Ju , Hsieh Shiuan , Li Chia-Wei
Published: August 2021

Background

In recent years, robots have been considered a new tech industry that can be used to solve the shortage in human resources in the field of health care. Also, animal-assisted therapy has been used to provide assistance, companionship, and interaction among the elderly and has been shown to have a positive impact on their emotional and psychological well-being. Both pets and robots can provide dynamic communication and positive interaction patterns. However, preferences for middle-aged and older adults in this regard are not clear.

Objective

This study explored the degree of acceptance of robots and pets as partners in later life and to determine the needs and preferences of elderly individuals related to companion robots.

Methods

A total of 273 middle-aged and older adults aged ≥45 years and living in the community were invited to answer a structured questionnaire after watching a companion robot video. Sociodemographic data, physical health status and activities, experience with technology, eHealth literacy, and acceptance and attitude toward robots and pets were recorded and analyzed using multinomial logistic regression analysis.

Results

Age, level of education, type of dwelling, occupation, retirement status, number of comorbidities, experience with pets, experience using apps, and eHealth literacy were significantly associated with acceptance of robots and pets. Middle-aged and older women preferred robots with an animal-like appearance, while men preferred robots that resembled a human adult. In terms of robot functions, participants preferred a companion robot with dancing, singing, storytelling, or news-reporting functions. Participants’ marital status and whether or not they lived alone affected their preference of functions in the companion robot.

Conclusions

Findings from this study inform the development of social robots with regard to their appearance and functions to address loneliness in later life in fast-aging societies.
Construction of Genealogical Knowledge Graphs From Obituaries: Multitask Neural Network Extraction System
Authors: He Kai , Yao Lixia , Zhang JiaWei , Li Yufei , Li Chen
Published: August 2021

Background

Genealogical information, such as that found in family trees, is imperative for biomedical research such as disease heritability and risk prediction. Researchers have used policyholder and their dependent information in medical claims data and emergency contacts in electronic health records (EHRs) to infer family relationships at a large scale. We have previously demonstrated that online obituaries can be a novel data source for building more complete and accurate family trees.

Objective

Aiming at supplementing EHR data with family relationships for biomedical research, we built an end-to-end information extraction system using a multitask-based artificial neural network model to construct genealogical knowledge graphs (GKGs) from online obituaries. GKGs are enriched family trees with detailed information including age, gender, death and birth dates, and residence.

Methods

Built on a predefined family relationship map consisting of 4 types of entities (eg, people’s name, residence, birth date, and death date) and 71 types of relationships, we curated a corpus containing 1700 online obituaries from the metropolitan area of Minneapolis and St Paul in Minnesota. We also adopted data augmentation technology to generate additional synthetic data to alleviate the issue of data scarcity for rare family relationships. A multitask-based artificial neural network model was then built to simultaneously detect names, extract relationships between them, and assign attributes (eg, birth dates and death dates, residence, age, and gender) to each individual. In the end, we assemble related GKGs into larger ones by identifying people appearing in multiple obituaries.

Results

Our system achieved satisfying precision (94.79%), recall (91.45%), and F-1 measures (93.09%) on 10-fold cross-validation. We also constructed 12,407 GKGs, with the largest one made up of 4 generations and 30 people.

Conclusions

In this work, we discussed the meaning of GKGs for biomedical research, presented a new version of a corpus with a predefined family relationship map and augmented training data, and proposed a multitask deep neural system to construct and assemble GKGs. The results show our system can extract and demonstrate the potential of enriching EHR data for more genetic research. We share the source codes and system with the entire scientific community on GitHub without the corpus for privacy protection.
A Novel Mobile App (“CareFit”) to Support Informal Caregivers to Undertake Regular Physical Activity From Home During and Beyond COVID-19 Restrictions: Co-design and Prototype Development Study
Authors: Egan Kieren J , Hodgson William , Dunlop Mark D , Imperatore Gennaro , Kirk Alison , Maguire Roma
Published: August 2021

Background

Informal caregivers, or carers (unpaid family members and friends), are instrumental to millions worldwide for the ongoing delivery of health and well-being needs. The risk of crisis points (eg, hospitalizations) for caregivers increases with the absence of physical activity. The COVID-19 pandemic is highly likely to have increased the risk of crisis points for caregivers by increasing the amount of time spent indoors due to shielding and lockdown restrictions. Thus, accessible evidence-based tools to facilitate physical activity for caregivers indoors are urgently needed.

Objective

The aim of this study was to co-design and develop a novel mobile app to educate and support carers in the undertaking of regular physical activity at home during and beyond COVID-19 restrictions via integration of the transtheoretical model of behavior change and UK physical activity guidelines.

Methods

We co-designed a mobile app, “CareFit,” by directly involving caregivers, health care professionals, and social care professionals in the requirements, capturing, and evaluation phases of three Agile Scrum design and development sprints. Seven participants representing multistakeholder views took part in three co-design sessions, each of which was followed by a development sprint. Requirements for CareFit were grounded in a combination of behavioral change science and UK government guidelines for physical activity.

Results

Participants identified different barriers and enablers to physical activity, such as a lack of time, recognition of existing activities, and concerns regarding safely undertaking physical activity. Requirements analysis highlighted the importance of simplicity in design and a need to anchor development around the everyday needs of caregivers (eg, easy-to-use video instructions). Our final prototype app integrated guidance for undertaking physical activity at home through educational, physical activity, and communication components.

Conclusions

Integrating government guidelines with models of behavioral change into a mobile app to support the physical activity of carers is novel. We found that integrating core physical activity guidelines into a co-designed smartphone app with functionality such as a weekly planner and educational material for users is feasible. This work holds promise to fill the gap of effective physical activity solutions for caregivers both during and beyond the COVID-19 pandemic. Further work is now needed to explore the feasibility, acceptability, and usability of the approach in real-world settings.

Authors: Budhwani Suman , Fujioka Jamie Keiko , Chu Cherry , Baranek Hayley , Pus Laura , Wasserman Lori , Vigod Simone , Martin Danielle , Agarwal Payal , Mukerji Geetha
Published: August 2021

Background

Virtual care delivery within mental health has increased rapidly during the COVID-19 pandemic. Understanding facilitators and challenges to adoption and perceptions of the quality of virtual care when delivered at scale can inform service planning postpandemic.

Objective

We sought to understand consistent facilitators and persistent challenges to adoption of virtual care and perceived impact on quality of care in an initial pilot phase prior to the pandemic and then during scaled use during the pandemic in the mental health department of an ambulatory care hospital.

Methods

This study took place at Women’s College Hospital, an academic ambulatory hospital located in Toronto, Canada. We utilized a multimethods approach to collect quantitative data through aggregate utilization data of phone, video, and in-person visits prior to and during COVID-19 lockdown measures and through a provider experience survey administered to mental health providers (n=30). Qualitative data were collected through open-ended questions on provider experience surveys, focus groups (n=4) with mental health providers, and interviews with clinical administrative and implementation hospital staff (n=3).

Results

Utilization data demonstrated slower uptake of video visits at launch and prior to COVID-19 lockdown measures in Ontario (pre-March 2020) and subsequent increased uptake of phone and video visits during COVID-19 lockdown measures (post-March 2020). Mental health providers and clinic staff highlighted barriers and facilitators to adoption of virtual care at the operational, behavioral, cultural, and system/policy levels such as required changes in workflows and scheduling, increased provider effort, provider and staff acceptance, and billing codes for physician providers. Much of the described provider experiences focused on perceived impact on quality of mental health care delivery, including perceptions on providing appropriate and patient-centered care, virtual care effectiveness, and equitable access to care for patients.

Conclusions

Continued efforts to enhance suggested facilitators, reduce persistent challenges, and address provider concerns about care quality based on these findings can enable a hybrid model of patient-centered and appropriate care to emerge in the future, with options for in-person, video, and phone visits being used to meet patient and clinical needs as required.

Authors: Yan Qi , Jensen Katherine , Field Alyssa , Goei Christian , Dao Campi Haisar E , Logue Alicia , Perry W Brian , Davies Mark G
Published: August 2021

Background

Websites are an important source of information for fellowship applicants, as they can influence ongoing interest and potential program selection.

Objective

This study aims to evaluate the current state of colorectal fellowship websites.

Methods

This cross-sectional study evaluates the quantity and quality of information available on websites of colorectal fellowship programs verified by the Accreditation Council for Graduate Medical Education in 2019.

Results

A total of 63 colorectal fellowships were included for evaluation. Websites were surveyed for content items that previous studies have found to be influential to program applicants. The 58 (91%) programs with a functional website were evaluated using an information index (calculated as a function of availability of content items concerning education, application, personnel, and benefits) and an interactive index (calculated as a function of accessibility and usability of the webpage). Programs had a median total score of 27.8 (IQR 21.5-34.5) of 79. The median score for the interactive index was 7.5 of 15 and for the information index was 20 of 64. The median scores for website application, education, personnel, and benefits or life considerations were 5, 5.5, 3.3, and 4 of 13, 24, 13, and 14, respectively. There was no difference in total score between programs in different geographical regions (P=.46).

Conclusions

Currently, colorectal surgery fellowship program websites do not provide enough content for applicants to make informed decisions. All training programs, regardless of specialty, should evaluate and improve their digital footprint to ensure their websites are accessible and provide the information desired by applicants.
Feasibility and Acceptability of a Web-Based Caregiver Decision Aid (Safety in Dementia) for Firearm Access: Pilot Randomized Controlled Trial
Authors: Betz Marian E , Polzer Evan , Nearing Kathryn , Knoepke Christopher E , Johnson Rachel L , Meador Lauren , Matlock Daniel D
Published: August 2021

Background

Firearms are common in the households of persons with Alzheimer disease and related dementias (ADRD). Safety in Dementia (SiD) is a free web-based decision aid that was developed to support ADRD caregivers in addressing firearm access.

Objective

We aimed to evaluate the feasibility and acceptability of SiD among a web-based sample of ADRD caregivers.

Methods

SiD was tested in 2 phases by using participants who were recruited from a web-based convenience sample (Amazon Mechanical Turk participants). In phase 1, caregivers were randomized to view either the intervention (SiD) or the control (Alzheimer’s Association materials), and the blinding of participants to the study arms was conducted. In phase 2, caregivers of individuals with ADRD and firearm access were recruited; all of these participants viewed the firearm section of SiD. In both phases, participants viewed SiD independently for as long as they wanted. Measures for evaluating decision-making and SiD acceptability were used, and these were assessed via a self-administered web-based questionnaire.

Results

Participants were recruited for phases 1 (n=203) and 2 (n=54). Although it was feasible to collect the study outcome data in a web-based format, in phase 1, there were no significant differences between SiD and the control in terms of decision-making and self-efficacy. The majority (137/203, 67.5%) of phase 1 participants spent between 5 and 10 minutes reviewing the resources. In phase 2, 61% (33/54) of participants spent 5 to 10 minutes viewing the firearm section, and 31% (17/54) spent 10 to 20 minutes viewing this section. Usability and acceptability were high across the phases.

Conclusions

SiD represents a new resource for promoting safety among people with dementia, and high acceptability was achieved in a pilot trial. In this sample, SiD performed similarly to Alzheimer’s Association materials in supporting decision-making and self-efficacy.

Authors: Lee Hocheol , Noh Eun Bi , Park Sung Jong , Nam Hae Kweun , Lee Tae Ho , Lee Ga Ram , Nam Eun Woo
Published: August 2021

Background

The US Centers for Disease Control and Prevention and the World Health Organization emphasized vaccination against COVID-19 because physical distancing proved inadequate to mitigate death, illness, and massive economic loss.

Objective

This study aimed to investigate Korean citizens’ perceptions of vaccines by examining their views on COVID-19 vaccines, their positive and negative perceptions of each vaccine, and ways to enhance policies to increase vaccine acceptance.

Methods

This cross-sectional study analyzed posts on NAVER and Instagram to examine Korean citizens’ perception of COVID-19 vaccines. The keywords searched were “vaccine,” “AstraZeneca,” and “Pfizer.” In total 8100 posts in NAVER and 5291 posts in Instagram were sampled through web crawling. Morphology analysis was performed, overlapping or meaningless words were removed, sentiment analysis was implemented, and 3 public health professionals reviewed the results.

Results

The findings revealed a negative perception of COVID-19 vaccines; of the words crawled, the proportion of negative words for AstraZeneca was 71.0% (476/670) and for Pfizer was 56.3% (498/885). Among words crawled with “vaccine,” “good” ranked first, with a frequency of 13.43% (312/2323). Meanwhile, “side effect” ranked highest, with a frequency of 29.2% (163/559) for “AstraZeneca,” but 0.6% (4/673) for “Pfizer.” With “vaccine,” positive words were more frequently used, whereas with “AstraZeneca” and “Pfizer” negative words were prevalent.

Conclusions

There is a negative perception of AstraZeneca and Pfizer vaccines in Korea, with 1 in 4 people refusing vaccination. To address this, accurate information needs to be shared about vaccines including AstraZeneca, and the experiences of those vaccinated. Furthermore, government communication about risk management is required to increase the AstraZeneca vaccination rate for herd immunity before the vaccine expires.

Published: August 2021

Na educação de jovens e adultos o conceito de trabalho – a partir das concepções marxistas, que o compreende em seu sentido histórico, como emprego assalariado e também em seu sentido ontológico, como forma de autorrealização humana – assume um papel de destaque, principalmente na integração da educação básica à educação profissional.  A educação, nessa acepção, deve almejar a emancipação completa dos seres humanos, ultrapassando as dicotomias que separam fazer intelectual de fazer manual, corpo e mente, emoção e razão. Considerar uma educação dos sentidos, englobando um saber além do intelectualizado, mas produzido pelo próprio corpo, e nele organizado e encarnado antes do intermédio da consciência, é de primordial importância para a formação integral do ser humano, não o reduzindo a um ser cindido que se forma para atender somente às necessidades imediatas da sociedade capitalista. O presente artigo visa trazer contribuições, a partir do Teatro do Oprimido, para uma educação dos sentidos na Educação de Jovens e Adultos.

Wireless Transmission of Solar Power
Authors: Bhardwaj Ajay
Published: August 2021

The Solar Power Satellite (SPS) is an energy system that collects solar energy in the upper atmosphere and transfers it to the ground. It has been seen as one of the best ways to alleviate the problem of future electricity needs. In the times to come, wireless power transmission will be used as it requires less maintenance and numerous other benefits. Solar energy is used for wireless power transmission. The wireless transmission concept was first realized by Nikola Tesla. Wireless transmission can bring about a noticeable change in the field of electrical engineering, which can lead to the fact that traditional copper wire is no longer used. For this project we used renewable energy as a source for wireless energy transmission. The DC output voltage of the solar cell is increased with a step-up converter and converted into oscillating signals. These oscillating signals are amplified via an amplifier and then supplied to the transmitting coil. By operating at the resonant frequency and achieving good coupling between the transmitter and receiver coils, electrical energy is transmitted between the transmitter and receiver due to the Magnetic resonance.

Demand Side Management Techniques for Peak Reduction
Authors: Kumar D. Sai
Published: August 2021

Industrial growth is the back bone for the development of any nation. Industries are mainly dependent on electrical energy. But from the various studies, the sources for electrical energy are decreasing gradually, and in turn, the gap is increasing between the supplier and the load. The solution for this scenario is optimal utilization of resources. To overcome this problem , the concept Demand Side Management (DSM) has emerged in Power System Planning and Management. The principle objective of DSM is mutual understanding between the supplier and the consumer for maximizing benefits and minimizing inconvenience. The aim of this research work is selection and application of appropriate DSM techniques to industrial and domestic loads for peak load management and energy conservation, that is to control the maximum demand during the peak hours and saving the energy by using the energy efficient and intelligent appliances like air conditioners and water heaters. DSM includes techniques like the End Use Equipment Control, the Load Priority Technique, he Peak Clipping & Valley filling, the Differential Tariff and Resizing of the equipment. Depending upon the application, all the techniques may be applied sequentially, or only a few of them can be applied. There is a lot of ambiguity in the selection of DSM techniques, because the application of each DSM technique depends on the case study and the problem associated with the respective case study. After comprehensive understanding of a particular case, a thorough investigation and subsequent data analysis pave the way for the selection of appropriate DSM technique/techniques

Analysis of Heat Transfer and Natural Convective of a Phase Change Material
Authors: Kumar T. Ravi
Published: August 2021

A phase-change material (PCM) is a substance with a high latent heat storage capacity which on melting and solidifying at a certain temperature, is capable of storing and releasing large amounts of energy. Various PCM like Paraffin wax, stearic acid are considered which are used to absorb heat from the coolant water from the engine. The conduction and convection criterion of heat transfer enable the PCM to store this heat as latent heat. The amount of convection and temperature change brought about due to the heat flux has been simulated and studied in detail using FLUENT. The thermal energy storage device (TESD) works on the effect of absorption and rejection of heat during the solid-liquid phase change of heat storage material. The overall function of the TESS is dominated by the PCM. The PCM material should be selected considering the application and the working conditions. Depending on the applications, the PCMs should first be selected based on their melting temperature for heat recovery system.

In this paper, we have modeled and simulated the magnetic field of the conductor by using the finite element method, which is incorporated in Ansoft Maxwell software. Modeling and simulation are done for a conductor and two conductors located at a small distance between them. Our study is based on the method of finite elements and Biot-Savart law for calculating the magnetic field depending on the distance from the conductor. We have observed that the calculated values of the magnetic field are in good accordance with Biot-Savart law [1]. We have found that magnetic field normal to the main axis of the conductor falls linearly towards it, whereas outside the conductor magnetic field is inversely proportional to distance. In the case of simultaneous calculation of the field inside and outside the conductor, a small margin has been found. This difference is as a result of the simultaneous calculation of magnetic field in two environments with different magnetic permeability. Finally, we have computed the magnetic field at an equal point between two conductors when the currents have opposite and same direction, whereby a huge difference between the magnetic fields is found. We show that we can amplify or reduce the intensity of the magnetic field, based not only on the distance between the conductors but also on the basis of the directions of the currents flowing through these conductors.

Nesta entrevista, o sociolinguista Philippe Blanchet aborda o tema da discriminação linguística, definida por ele como glotofobia. Blanchet contribuiu enormemente para a conceituação deste fenômeno e vem atuando na luta contra este tipo de segregação social. Esta entrevista foi realizada meses após o término do meu estágio de doutorado sob sua direção, auxiliado pela Professora Gudrun Ledegen, no laboratório PREFICS (Pôle de Recherche Francophonies, Interculturel, Communication, Sociolinguistique), na Université de Rennes 2. Esse estágio foi realizado no âmbito do projeto de internacionalização CAPES-PrInt  "Multilinguismo, direitos linguísticos e desigualdade social", da Universidade Federal Fluminense.
Epistemologia da errância: a sedentarização da significação na linguagem científica
Authors: Almeida João Flávio de
Published: August 2021

O objetivo deste artigo é apresentar de forma introdutória as noções de errância e sedentarismo como figuras teóricas para a concepção de uma Epistemologia da Errância, tal como proposta em “Epistemologia da Errância: erro, hiância e ciência em discurso” (ALMEIDA, 2019). Este olhar epistemológico tem como foco interrogar a produção, a circulação e os efeitos dos saberes científicos na contemporaneidade para, a partir disso, propor um novo olhar e uma nova forma de escuta de saberes denegados e foracluídos dos muros acadêmicos. Neste artigo, o itinerário teórico passa por uma breve apresentação dos conceitos, mas detém-se principalmente em resgatar da historiografia os primeiros modelos de relação do ser humano com o mundo, a saber, errância, nomadismo e sedentarismo - atentando-se às peculiaridades de seus funcionamentos -, para então propor a partir deles um aparato teórico-analítico sobre a epistemologia dos saberes científicos na contemporaneidade.
