Published: November 2023

Nanorobotic motion on solid substrates is greatly hindered by strong nanofriction, and powerful nanomotors‒the core components for nanorobotic motion‒are still lacking. Optical actuation addresses power and motion control issues simultaneously, while conventional technologies with small thrust usually apply to fluid environments. Here, we demonstrate micronewton-thrust nanomotors that enable the autonomous nanorobots working like conventional robots with precise motion control on dry surfaces by a photothermal-shock technique. We build a pulsed laser-based actuation and trapping platform, termed photothermal-shock tweezers, for general motion control of metallic nanomaterials and assembled nanorobots with nanoscale precision. The thrust-to-weight ratios up to 107 enable nanomotors output forces to interact with external micro/nano-objects. Leveraging machine vision and deep learning technologies, we assemble the nanomotors into autonomous nanorobots with complex structures, and demonstrate multi-degree-of-freedom motion and sophisticated functions. Our photothermal shock-actuation concept fundamentally addresses the nanotribology challenges and expands the nanorobotic horizon from fluids to dry solid surfaces.

Authors: Kurniawan Edy , O-Thong Sompong , Imai Tsuyoshi
Published: November 2023

Thermotolerant caproic acid-producing bacteria were isolated from sewage sludge and evaluated for caproic acid production with various substrates. The ethanol-acetate was the most efficient substrate for enriched culture, with 2.7 g/L caproic acid and a yield of 47%. Clostridium strain M1NH was isolated from enriched culture and identified as a gram-positive, rod-shaped, spore-forming with 92% similarity of 16S rRNA to Clostridium kluyveri. Clostridium M1NH has an optimal pH and temperature of 6-6.5 and 35–40°C with a growth rate of 0.11–0.14 h-1, suggesting that the strain was thermotolerant. Clostridium strain M1NH displays the highest caproic acid production of 3.2–3.5 g/L at a pH of 6.5, a temperature of 35–40°C, and an ethanol-acetate molarity ratio of 4:1. Clostridium strain M1NH is tolerant to concentrations of ethanol, acetate, and caproic acid of 5%, 5%, and 2%, respectively. The thermotolerant Clostridium M1NH presents a significant advancement in harnessing sustainable biobased production processes, holding great promise for applications in thermotolerant fermentation.

Published: November 2023

Background: The lack of sufficient research on wearing contact lenses, and the most common symptoms and complications that lens wearers complain about in the Arab world, and Syria in particular, despite their widespread use, is what prompted us to conduct this study.
Methods: A cross-sectional study, conducted on students at the Syrian Private University. Data was collected between 10/27/2022 and 4/7/2023, and we obtained 1,750 responses. After including only students who are still studying at the university and who wear contact lenses, we arrived at a sample of 500 students.
Results: The study included 500 students. Females constituted most of the study sample (89%), compared to males (11%). The average age of the students was 22.41 years. Nonsmoking students constituted the largest percentage (43%), and most students reported that they did not work (81%). Human medicine students constituted the largest percentage of participating colleges (26%). More than half of students (65%) use lenses without a doctor's prescription. Most students wear lenses with both eyes (98%), compared to 2% who wear them with only one eye. The largest percentage of people wearing contact lenses was cosmetic (44%). Type of contact lenses used; the largest percentage was for flexible lenses (57%). The most common symptoms are dry eyes (58%), redness of the conjunctiva (36%), puffiness of the eyelids (20%), white purulent discharge (17%), and finally sticking of the eyelids when waking up from sleep (13%).
Incommensurate to normal phase transition in malayaite

Published: November 2023

We report variable temperature X-ray diffraction (20 K < T < 295 K) and Raman scattering (90 K < T < 400 K) data of malayaite, the tin analog of the mineral titanite, aided by results from density functional perturbation theory. The phase transition from the normal to the incommensurately modulated crystal structure occurs at Tc = 50 ± 2 K with an almost constant q-vector of 0.27b*. Some first order satellite diffraction maxima are observable up to 55 K, where they increasingly broaden toward the main reflections. Softening of the lowest frequency transverse optical Bg phonon mode, dominated by antiparallel motion of Ca atoms, is observed on cooling from 400 to 90 K. This confirms the displacive character of the transition to the modulated structure, indicated by the instability of this phonon mode in the zero-temperature approximation of first principle computation. The transition to the incommensurately modulated phase is preceded by a temperature region of anomalous thermal expansion in the normal phase, marked by negative thermal expansion along [010] and consequently a change from hardening to softening phonon modes on cooling below 150 K. The modulated phase of malayaite highlights the potential of density functional perturbation theory for the discovery of hitherto unknown ground state structures of minerals.

Published: November 2023

Risk aversion plays a crucial role in understanding how individuals make financial decisions and allocate their resources. This study analyzes the influence of risk aversion on behavioral intentions and explores the mediating role of attitudes, subjective norms, and perceived behavioral control. Additionally, it investigates the moderating effect of gender and financial literacy on behavioral intentions of investors. A sample of 400 people was collected from Indian retail investors by administering a structured questionnaire through stock brokering firms, and data were analyzed using Partial least squares – Structural equation modelling in the Smart PLS 3.3.9 software. The research found that risk aversion, attitude, subjective norms, and perceived behavioral control significantly impact an investor’s intention. Among all the antecedents of behavioral intentions, perceived behavioral control (β 0.481*) was found as a significant predictor of the intention compared to attitude (β 0.154*), subjective norms (β 0.224*) and risk aversion (β 0.082*) factors. Further, mediation analysis found that attitude, subjective norms, and perceived behavioral control partially mediated the relationship between risk aversion and intention. Lastly, the multi-group analysis revealed that gender and financial literacy did not moderate the association between risk aversion and intention.

Published: November 2023

Antibiotics can contaminate the environment as a result of improper disposal. The induction of doxycycline in the environment could give rise to lineages of the cucurbit beetle Diabrotica speciosa containing resistant endosymbiotic microorganisms, giving rise to bacterial strains capable of biodegrading these antibiotic residues. This work determined the relationship between the intestinal microbiota of D. speciosa and its ability to biodegrade an antibiotic. Bacterial strains of Enterobacter cloacae and Stenotrophomonas maltophila isolated from the gastrointestinal tract of D. speciosa were evaluated for the biodegradation of doxycycline. An analytical method for the extraction and quantification of doxycycline by high-efficiency liquid chromatography-ultraviolet detection (HPLC-UV) was developed and applied to monitor the biodegradation rates during bacterial growth for nutrient and nutrient-deficient media, both supplemented with the antibiotic. Degradation kinetics showed a decrease in antibiotic concentration after 96 h in saline medium, with recoveries of 63.1 and 87.7% for E. cloacae and S. maltophilia, respectively. Two degradation products were then identified and characterized from the liquid chromatography-high resolution mass spectrometry data after bioassays with E. cloacae. The gastrointestinal tract of insects such as D. speciosa can be a source of useful microbes for biotechnological processes such as the biodegradation of exogenous organic compounds in the environment.

The main idea of this study was to quantify the relationship between climatic variables and tympanic body temperature recorded through the use of wireless sensors in grazing cows located in low tropic. Material and methods. The tympanic temperature of twenty-eight cross breed grazing cows in early lactation was monitored. The sensors were manually installed in the tympanic cavity, recording hourly for 17 days. The climate data was obtained from the network of weather stations of the Centro de Investigación de la Caña de Azúcar “Cenicaña”, which is a research center for sugarcane located in Cali, Colombia, this data was analyzed for the same time interval of the temperature. The information was analyzed using descriptive statistics, correlation matrices and Random Forest models, through the R software. Results. From the physiological data from automatic collection systems, the response variables that would allow the evaluation of thermoregulation processes were analyzed using big data. We find that the variables environmental temperature, relative humidity and, solar radiation were the factors that most influenced the homeothermic adaptation process of the animals. Conclusions. The introduction of remote devices, and the use of a large amount of data for the analysis of physiological indicators, avoid modifying natural animal behavior and emerges as an important diagnostic and management strategy in the livestock farm, helping in the studies of heat stress, physiological adaptation and, prevalence to hemotropic diseases, which reduce the productivity of the systems.

Nutrition counseling may assist liver transplant patients in controlling weight gain, addressing micronutrient deficiencies, and maintaining metabolic status. This study aimed to determine the effect of nutritional counseling on nutritional status, liver profile, and serum electrolytes of liver transplant patients. In this case-control study, 100 patients were recruited from Shifa International Hospital, Islamabad, who were potential liver transplant candidates. They were divided into two groups: a case group, who were given nutrition counseling (n = 50), and a control group, who were not provided nutrition counseling (n = 50). Data was collected about patients' socio-economic status, medical history, anthropometric, biochemical and dietary profiles. Independent t-tests, chi-square tests for qualitative frequency distribution, and paired t-tests were used. At baseline, the weight and BMI of the case and control were comparable, but there was a non-significant difference. Nutrition counseling was effective in improving biochemical variables (potassium at preoperative, sodium and albumin during illness; p-value < 0.05), Liver function (ALT at preoperative and postoperative, AKT at preoperative, during sickness and postoperative; p-value < 0.05) and macronutrient profile (fat intake during illness and protein intake during postoperative stage; p-value < 0.05) in case group as compared to control. Effective nutrition counseling improves liver transplant patients' nutritional status, liver function, and serum electrolytes.
Versatile Surface Chemistry of Carbon-Based Nanoplatforms by Covalent Bonding, Non-Covalent Linking, Crosslinking, and Self-Assembling
Authors: Bracamonte A. Guillermo
Published: November 2023

This mini-review discussed the best-known chemical and synthetic methodologies used in the last years to modify carbon allotropes, with an interest in nanotechnology. In this perspective, chemistry with optoelectronics applications and recent trends within bio-applications focusing mainly on graphene and its derivatives were considered. So, the mini-review intended to focus on methodologies to add functional groups with varied reactivities, polymer chemistry, and nanoscale control. These methodologies provide insight for further developments. In this manner, traditional methods using strong acid media to convert simple carbon bonds into carboxylic acid and aldehydes organic functional groups were shown and discussed. Hence, chemical modifications in a variety of solvents could be developed. Notably, many organic chemical reactions, such as bimolecular nucleophilic substitution (SN2), click chemistry, and photochemical reactions, showed essential insights in designing the carbon-based material modifications and the bottom-up method. Moreover, incorporating atomic entities within graphene material defects led to interesting spectroscopic and quantum properties. The atomic change added blemishes to this homogeneous structure, which was tuned to modify optical properties. In addition, the review was also oriented towards the discussion on incorporating polymeric films, such as boron- and silicon-based monomers, to form polymeric-modified carbon-based slides. In this way, organoboranes and organosilanes permitted chemical functionalization because their chemical modification was more accessible on nanosurfaces. Moreover, emphasis was placed on exploiting non-covalent bonding with ions and polarized molecules with the highly electronic densities of graphene and its derivatives. In this manner, the manuscript intends to summarize the main types of reactions and synthetic pathways reported until today. Therefore, particular focus was given to chemical composition, 2D and 3D chemical structures, and their properties related to non-covalent interactions. Thus, based on the properties and reactivity of carbon allotropes, the review was intended to open the analysis and discussion, considering the design of new carbon-based materials, hybrid nanocomposites, and metamaterials.

Patient Characteristics Associated With Phone and Video Visits at a Tele-Urgent Care Center During the Initial COVID-19 Response: Cross-Sectional Study
Authors: Khairat Saif , John Roshan , Pillai Malvika , McDaniel Philip , Edson Barbara
Published: November 2023

Background

Health systems rapidly adopted telemedicine as an alternative health care delivery modality in response to the COVID-19 pandemic. Demographic factors, such as age and gender, may play a role in patients’ choice of a phone or video visit. However, it is unknown whether there are differences in utilization between phone and video visits.

Objective

This study aimed to investigate patients’ characteristics, patient utilization, and service characteristics of a tele-urgent care clinic during the initial response to the pandemic.

Methods

We conducted a cross-sectional study of urgent care patients using a statewide, on-demand telemedicine clinic with board-certified physicians during the initial phases of the pandemic. The study data were collected from March 3, 2020, through May 3, 2020.

Results

Of 1803 telemedicine visits, 1278 (70.9%) patients were women, 730 (40.5%) were aged 18 to 34 years, and 1423 (78.9%) were uninsured. There were significant differences between telemedicine modalities and gender (P<.001), age (P<.001), insurance status (P<.001), prescriptions given (P<.001), and wait times (P<.001). Phone visits provided significantly more access to rural areas than video visits (P<.001).

Conclusions

Our findings suggest that offering patients a combination of phone and video options provided additional flexibility for various patient subgroups, particularly patients living in rural regions with limited internet bandwidth. Differences in utilization were significant based on patient gender, age, and insurance status. We also found differences in prescription administration between phone and video visits that require additional investigation.

Authors: Gödde Daniel , Nöhl Sophia , Wolf Carina , Rupert Yannick , Rimkus Lukas , Ehlers Jan , Breuckmann Frank , Sellmann Timur
Published: November 2023

BACKGROUND

ChatGPT is a 175-billion-parameter natural language processing model that is already involved in scientific content and publications. Its influence ranges from providing quick access to information on medical topics, assisting in generating medical and scientific articles and papers, performing medical data analyses, and even interpreting complex data sets.

OBJECTIVE

The future role of ChatGPT remains uncertain and a matter of debate already shortly after its release. This review aimed to analyze the role of ChatGPT in the medical literature during the first 3 months after its release.

METHODS

We performed a concise review of literature published in PubMed from December 1, 2022, to March 31, 2023. To find all publications related to ChatGPT or considering ChatGPT, the search term was kept simple (“ChatGPT” in AllFields). All publications available as full text in German or English were included. All accessible publications were evaluated according to specifications by the author team (eg, impact factor, publication modus, article type, publication speed, and type of ChatGPT integration or content). The conclusions of the articles were used for later SWOT (strengths, weaknesses, opportunities, and threats) analysis. All data were analyzed on a descriptive basis.

RESULTS

Of 178 studies in total, 160 met the inclusion criteria and were evaluated. The average impact factor was 4.423 (range 0-96.216), and the average publication speed was 16 (range 0-83) days. Among the articles, there were 77 editorials (48,1%), 43 essays (26.9%), 21 studies (13.1%), 6 reviews (3.8%), 6 case reports (3.8%), 6 news (3.8%), and 1 meta-analysis (0.6%). Of those, 54.4% (n=87) were published as open access, with 5% (n=8) provided on preprint servers. Over 400 quotes with information on strengths, weaknesses, opportunities, and threats were detected. By far, most (n=142, 34.8%) were related to weaknesses. ChatGPT excels in its ability to express ideas clearly and formulate general contexts comprehensibly. It performs so well that even experts in the field have difficulty identifying abstracts generated by ChatGPT. However, the time-limited scope and the need for corrections by experts were mentioned as weaknesses and threats of ChatGPT. Opportunities include assistance in formulating medical issues for nonnative English speakers, as well as the possibility of timely participation in the development of such artificial intelligence tools since it is in its early stages and can therefore still be influenced.

CONCLUSIONS

Artificial intelligence tools such as ChatGPT are already part of the medical publishing landscape. Despite their apparent opportunities, policies and guidelines must be implemented to ensure benefits in education, clinical practice, and research and protect against threats such as scientific misconduct, plagiarism, and inaccuracy.

UNSTRUCTURED

In healthcare, where increasing efficiency is essential to the demand of scale, there is immense opportunity to incorporate advances in artificial intelligence (AI). However, particularly in healthcare, these technologies must be designed to be both effective and ethical. Our objective in a multidisciplinary international roundtable discussion (Canada, United States, United Kingdom), was to identify concepts, perspectives, and considerations for AI systems in healthcare settings that are designed, developed, and deployed with good intention to empower patients and healthcare providers in a safe, trustworthy, and ethical way. We refer to this notion as responsible AI (RAI). First, we discuss the role and opportunity of AI to support collaborative healthcare (clinicians and patients working together) and increase specialist capacity. Second, we outline risks and ramifications of poorly implemented AI including bias, implications of predictors to support diagnosis, and privacy and security considerations. Third, we discuss how these risks can be mitigated through conducting “good science” by addressing biases such as representative data, probing annotation bias, and the role of the biostatistician. We also outline the need to evaluate fit for purpose through transdisciplinary collaboration to address: explainability, fairness, interpretability, transparency, as well as the role of standards, auditing, and regulatory considerations. Finally, we detail four criteria outlining determinants, considerations and rationale for developing RAI. These determinants and considerations are meant to position new AI-powered healthcare technologies primed for responsible design supporting acceptability, appropriateness, feasibility, and adoption. Future directions should expand on additional factors and monitor responsible AI implementation success to validate these criteria.
Solid runoff of the Don River and suspended matter flow into the delta during surges: statistical modeling and comparison in the low water period
Authors: Likhtanskaya Nataliya , Berdnikov Sergey , Kleshchenkov Alexey
Published: November 2023

Statistical modeling of the Don River solid runoff based on water discharge and turbidity measurements obtained at the hydrological station in the village of Razdorskaya for the twelve-year period 2009–2020 was carried out. The WRTDS (Weighted Regressions on Time, Discharge, and Season) and WRTDSKalman (WRTDS with Kalman filtering) methods were applied. The developed statistical model is aimed at solving the problem of the imbalance between the regularity of collecting data on water discharge and data on the concentration of suspended matter by “restoring” the concentration values on days without measurements based on data on the most “similar” days with measurements in terms of time, discharge and season and does not claim to describe a relationship between the concentration of the constituent of interest and discharge. The quality of the developed statistical model and its modification were checked. The average daily concentrations and fluxes of suspended matter were compared with estimates of the volumes of suspended material deposited during periods of recurring strong surge phenomena. A comparative assessment of sea and river factors contributions to the transport and sedimentation of suspended matter in the Don River delta was fulfilled.

Este artículo, basado en una revisión bibliográfica y de documentos legales, busca investigar cuál es el modelo regulatorio que el país está a punto de adoptar y si el camino brasileño está en armonía con las directrices de la Recomendación emitida por la Organización para la Cooperación y el Desarrollo Económico - OCDE.
lucha contra la violencia de género en la Unión Europea:
Authors: Borges Blázquez Raquel
Published: November 2023

La falta de un concepto de violencia de género a nivel europeo complica el reconocimiento mutuo de resoluciones penales en la Unión Europea. La redacción de un concepto de violencia de género es algo técnicamente sencillo pero políticamente complejo. Las distintas sensibilidades frente al problema de la violencia de género sitúan a la Unión en una encrucijada de difícil solución. Al legislador europeo se le presentan dos alternativas. La primera es la creación de una directiva de mínimos para así conseguir un respaldo sin oposición de todos los países del entorno. La segunda alternativa corresponde a una apuesta decidida por luchar contra la lacra social de la violencia contra las mujeres, forzando así a los legisladores nacionales con menor conciencia social del problema a adaptar sus legislaciones.
Searches and Seizures in the Digital Age—The Need For a Prior Independent Oversight Among International and European Standards
Authors: Bernardini Lorenzo
Published: November 2023

The relentless march of technological progress has significantly streamlined the collection, transmission, and electronic storage of personal information, reshaping the landscape of searches and seizures of electronic devices. This digital evolution allows prosecuting authorities unprecedented access to vast volumes of information stored on computers, raising concerns about the potential misalignment between seized documents and suspected criminal activities. Emphasizing the importance of procedural guarantees for individuals impacted by digital searches and seizures measures, scholars have traditionally advocated for prior authorization from an independent authority. Still, the mere presence of prior authorization does not guarantee non-arbitrary implementation of those measures. Amidst this framework, international standards prefer prior judicial oversight, with “freedom from arbitrariness” test guiding competent authorities in scrutinizing relevant case facts. Conversely, the European legal framework, especially Article 8 ECHR, lacks clarity, risking the fundamental nature of the right to privacy by allowing intrusive measures without prior control.

Authors: Olufemi Akinyosoye , Bolarinwa Balogun
Published: November 2023

Abstract: The presence of PFSs in urban areas has increased significantly, leading to conflicts with existing land use planning and violations of the minimum environmental safety requirements set by the Department of Petroleum Resources (DPR) and have adverse social and environmental impacts despite their socioeconimic importance. This paper aim to investigate the spatial distribution of petrol filling stations and their impact on groundwater quality in Akure Metropolis of Ondo State. A total of 147 PFSs and 140 water wells were identified and recorded. Laboratory analysis was done purposefully on wells near PFSs that were both 26 years or older and still functional, as older underground storage tanks (USTs) pose a potential threat to groundwater safety. Findings revealed 119 functional filling stations, 28% located within residential area and 68% domiciled in commercial areas, 2% in outskirt of town and 1% in standalone environment. Findings showed all mapped filling stations were found to be within 50m from built up (residential) area, 104 mapped stations within residential and commercial areas violates the DPR standard. Using spatial analysis, it was also found that 116 of the 147 (78.9%) mapped filling stations were within 400m away from the next. 108 of the 147 (73.47%) mapped PFSs violated the standard of distance not less than 15meters from the edge of the road to the nearest pump. The findings also showed that groundwater system is contaminated by PAHs, which comprises; naphthalene.F, pyrene and acenaphthylene.F. Low mean concentrations of PAHs recorded in this study suggest that there is no major compromise in the quality of groundwater due to the operation of PFSs in Akure metropolise Hand-dug Wells in the study area. It is recommended that spatial compliance for siting PFSs should be strictly adhered to in order to avoid disaster that may occur due to the hazard they pose

Abstract: Ever since notable advancements were made concerning Database Management and regulation in the early 2000s, Automation of Databases in the Oracle environment have long been a crucial topic for research and development within the Computer Science and Information Technology sector. This research paper aims to explain what all factors necessarily require automation whilst bringing into light the growing demand for automation database management. As organizations across the globe face the imminent issue of overwhelming volumes of data, efficient database management systems that offer minimum complications are highly in demand. The paper not only highlights automation of various tasks such as routine maintenance, performance tuning, backup and recovery routine, but also emphasises the importance of security enhancements, real-time monitoring and scalability whilst placing forth key requirements of automation in general. The research presents a smarter and more robust database system model that can manage itself without the need of constant monitoring or intervention. Furthermore, we discuss the combining of cloud-based technologies such as Oracle Cloud and other containerization techniques to make the database more flexible and sustainable, all while keeping in mind the importance of having absolute rules and procedures for managing data in an automated system, which ensures that the data is well-organized, complies with legal requirements and is ready to be audited for accountability if needed. To conclude, the paper suggests nurturing practices of setting up systems that keep track of changes and versions to automate the infrastructure and managing of databases more consistently and efficiently. As organizations delve deeper into the landscape of database automation, they inadvertently face several challenges such as accuracy, security and accessibility of the data. This research paper specifically explores the requirements that promise to reshape the future of data management.
Formas de vida wittgensteiniana e perspectivismo ameríndio: por uma linguística antropológica selvagem
Authors: El-Jaick Ana Paula Grillo
Published: November 2023

Partindo do pressuposto de que vivemos certa crise metodológica nas Humanidades – da qual os Estudos da Linguagem fazem parte –, este artigo propõe uma perspectiva de estudos discursivos que tenha como base a concepção de linguagem como forma(s) de vida tal como expressa pelo pensamento do L. Wittgenstein maduro. Concomitantemente, pretendemos reler a perspectiva wittgensteiniana de linguagem sob o olhar de outro perspectivismo: o ameríndio, conforme formulado pelo antropólogo brasileiro Eduardo Viveiros de Castro (2002, 2018). Desse modo, partindo de uma filosofia da linguagem ordinária, faremos uma leitura das formas de vida wittgensteiniana com lentes ameríndias. Como veremos, nossa concepção de linguagem tem como consequência epistemológica a inessencialidade de seus conceitos. Essa fugacidade resvala no próprio ser: o antropófago digere seu inimigo e lhe toma o nome, maior honraria alcançável ao transformar sua corporeidade. Entre os ameríndios, é no corpo que os entes – todos gente – se (des)identificam entre si. O sujeito, como a linguagem, se constitui, necessariamente, na/pela alteridade. Enfim, sujeito e linguagem são entes sempre em devir. As formas de vida são biológicas e culturais – ou melhor: não há essa distinção natureza / cultura. E isso não é um relativismo, mas um perspectivismo linguístico-antropológico.
A semiose como forma de vida: interações em uma conversa sinalizada
Authors: Da Silva João Paulo , Viotti Evani de Carvalho
Published: November 2023

Interações face-a-face caracterizam-se como um domínio privilegiado para o estudo da emergência do processo semiótico concebido como uma forma de vida. A partir da análise de trechos extraídos de uma conversa em língua de sinais brasileira (libras), exploramos a ideia de que todos os organismos habitam as ações uns dos outros (INGOLD, 2000), em processos dinâmicos em que significações emergem como forma de dar continuidade às atividades da própria vida. Essa habitação nas ações dos outros se revela por meio da realização de ações co-operativas, que se definem como o reuso, com transformações, de elementos disponíveis na interação corrente ou recuperáveis a partir dos históricos de interações dos interactantes (GOODWIN, 2018). No curso de uma interação face-a-face, as ações co-operativas se caracterizam pela co-constituição mútua das atividades de diferentes partes do corpo de um mesmo interactante (ações intracorporeadas) com as atividades sincronizadas dos corpos dos dois (ou mais) interactantes (ações intercorporeadas), o que leva à emergência de significações sempre novas, de natureza local, temporal, corporeada e contingencial, como qualquer forma de vida.
