Effect of Gamification on the Development of Digital Competencies of Regular Basic Education Teachers
Authors: Robles Eliana Vanessa Collantes
Published: December 2024

In the digital age, teachers’ digital competencies are important for effective education, yet many educators, particularly in Latin America, lack these essential skills. While gamification has shown promise in various education contexts, its effectiveness for developing teachers’ digital competencies remains understudied, especially in the Latin American setting. This study aimed to examine the effect of gamification on the development of digital competencies of basic education teachers in Trujillo, Peru. A quasi-experimental design was used, and 60 primary-level teachers were selected through convenience sampling; they were randomly assigned to either an experimental (n = 30) or control (n = 30) group. The experimental group participated in a two?month program consisting of 15 gamified sessions, whereas the control group received no intervention. Data were collected via an adapted version of the Teacher Digital Competence Questionnaire in pretest and posttest phases. Descriptive statistics, Mann-Whitney U tests, and Kruskal-Wallis tests were employed for data analysis. The results reveal significant improvements in the experimental group’s digital competencies across all dimensions (information literacy, communication, content creation, safety, and problem-solving), with 93.3% achieving the “achieved” level postintervention, compared with 30% of the control group. Inferential analysis confirms significant differences between groups in the posttest phase (Mann-Whitney U = 96.5, p < .05). These findings suggest that gamification is an effective strategy for developing teachers’ digital competencies, and can contribute valuable empirical evidence to the field of education technology and holds important implications for teacher training and education policies in Latin America.

Authors: Brito Guadalupe William Xavier
Published: December 2024

El síndrome de takotsubo (STT) es una miocardiopatía de reconocimiento reciente, la cual se puede asemejar a un síndrome coronario agudo. El STT es una entidad transitoria y reversible, a pesar de que su pronóstico es bueno en la mayoría de los casos, existe un pequeño porcentaje que presenta complicaciones hospitalarias graves. El abordaje de estos pacientes requiere de atención optimizada por parte de un equipo multidisciplinar y experto. En consecuencia, el objetivo de la investigación es mostrar el abordaje o manejo de los pacientes con STT en la Unidad de Cuidados Críticos, desde el ingreso hospitalario, el diagnóstico y atención de emergencia, estadificación de los factores de riesgo, tratamiento y el seguimiento de estos casos. La metodología empleada es una revisión bibliográfico – documental. El STT es una entidad que tiene una presentación similar al infarto agudo de miocardio, por ende, el manejo inicial consiste en descartarlo. No obstante, su tratamiento de emergencia es similar al del infarto hasta encontrar el diagnóstico. El electrocardiograma es fundamental en su abordaje. El interTak score es un método diagnóstico usado internacionalmente en la identificación del síndrome de tako-tsubo. El tratamiento debe ser individualizado y comienza con el control del dolor y posibles complicaciones. Asimismo, los Betabloqueantes y los inhibidores de las enzimas convertidores de angiostensina (IECA) han demostrado su importancia en el manejo estos pacientes. Igualmente, la evidencia ha demostrado la importancia de los anticoagulantes en el tratamiento de este síndrome, especialmente en presencia de trombos intracardiacos. El seguimiento de estos casos es fundamental por cuanto pueden persistir en algunos pacientes síntomas a largo plazo.

La enfermedad de VEXAS es una patología inflamatoria de reciente descubrimiento. Al principio se creía que era una enfermedad rara, pero gracias a las investigaciones, en poco tiempo se ha conocido que es más común, variable y peligrosa de lo que se creía. Los acrónimos de VEXAS significan Vacuolas, Enzima E1, ligado al cromosoma X, Autoinflamatorio y Somático. Su característica principal es una mutación somática del gen UBA1. Este síndrome ocasiona una inflamación multisistémica, que afecta principalmente la piel, los pulmones y la médula ósea. Hasta la fecha los enfoques terapéuticos se basan en evidencia limitada, por tanto, sigue siendo inconsistente su efectividad. En consecuencia, el propósito de esta revisión es plasmar parte de la evidencia científica más actualizada acerca de los avances en el manejo del síndrome de VEXAS, específicamente en cuanto al tratamiento de esta patología autoinflamatoria. La metodología empleada es una revisión bibliográfico – documental. De la revisión se desprende que la enfermedad de VEXAS, no cuenta con un consenso para su tratamiento. Sin embargo, existen modelos terapéuticos estándares y recomendaciones basadas en la evidencia proporcionada hasta la fecha. Actualmente, el trasplante alogénico de células madre hematopoyéticas (TCPH) se ha convertido en el único tratamiento con intención curativa, sin embargo, conlleva a una serie de riesgos significativos y contraindicado, sobre todo en pacientes más frágiles. Múltiples estudios han demostrado la efectividad de otras terapias, las cuales se enfocan en un buen control inflamatorio, la disminución de complicaciones postrasplante, entre otras. Entre estas nuevas terapias encontradas en la literatura se pueden mencionar: Esteroides, Inhibidores de JAK, Abatacept, Inhibidores de IL-6, Inhibidores del TNF, Agentes hipometilantes, Terapia Chop, FAME convencionales: metotrexato, micofenolato, azatioprina, ciclofosfamida, Inmunoglobulinas intravenosas (IVIG) y Rituximab.

Published: December 2024

La inmunoterapia personalizada es una estrategia terapéutica que busca potenciar el propio sistema inmunológico de cada paciente para combatir enfermedades, principalmente el cáncer. A diferencia de los tratamientos tradicionales como la quimioterapia o la radioterapia, que atacan indiscriminadamente las células cancerosas y sanas, la inmunoterapia se enfoca en estimular las defensas del organismo para que reconozcan y eliminen específicamente las células tumorales. Para llevar a cabo esta revisión bibliográfica, se realizó una búsqueda exhaustiva en bases de datos científicas como PubMed, Scopus y Web of Science, utilizando combinaciones de términos clave como "inmunoterapia personalizada", "biomarcadores", "tratamientos inmunológicos", "oncología" y "medicina de precisión". Se consideraron artículos publicados en los últimos 15 años, en idioma inglés y español, con un enfoque en estudios originales, revisiones sistemáticas y metaanálisis. La inmunoterapia ha abierto nuevas vías para el tratamiento del cáncer, pero aún queda mucho por investigar. La identificación de nuevos biomarcadores y el desarrollo de estrategias de combinación terapéutica son áreas de investigación activa que permitirán mejorar la eficacia y seguridad de estos tratamientos.

Published: December 2024

Online transactions have the potential to violate consumers' data. However, current regulations do not fully protect consumers' privacy rights and personal data in this era of information technology. This study discusses the renewal of privacy rights protection laws based on the principles of Islamic economic law. Specifically, this study evaluates existing regulations and offers solutions based on the principles of Islamic economic law so that privacy rights protection is safer and more equitable. The research method uses normative juridical with a statutory, conceptual, comparative, and case approach. The results show that Islamic economic law principles prioritizing the values of justice, welfare, and transparency provide a comprehensive legal framework to protect consumers' privacy rights and personal data in online transactions. Applying Islamic economic law principles can increase consumer trust and encourage business actors to be ethically responsible in managing personal data. The proposed legal reform has the potential to create an online transaction ecosystem, especially e-commerce that is fairer, safer, and more sustainable, and protects consumers' privacy rights and personal data, with legal certainty. This research contributes to the law-making of protecting consumer privacy rights and personal data in the current digital era.

Published: December 2024

Introduction: Current treatment of idiopathic sudden sensorineural hearing loss (ISSNHL) includes a combination of corticosteroids and hyperbaric oxygen therapy (HBOT) without established dose. The objective of this study was to investigate whether > 10 HBOT treatments offers improved outcome over 10 treatments.
Methods: A retrospective chart review was performed of patients treated with HBOT for ISSNHL between 2013 and 2022 at the Royal Brisbane and Women’s Hospital. Pure tone average results from 500, 1,000, 2,000, 4,000 hertz (PTA4) were obtained pre-treatment, after treatment 10, and six weeks post-treatment.
Results: There were 479 patients treated for ISSNHL: 144 having audiograms six weeks post-treatment, 140 of whom also had an audiogram after treatment 10. At six weeks post treatment 22% (32/144) had normal hearing (PTA4 < 25 dB), and 69% (99/144) had a PTA4 gain ≥ 10 dB. At the treatment 10 audiogram, 83/140 (59%) were improved. From these, 5/21 (24%) with 10 treatments and 14/57 (25%) with > 10 treatments had a further PTA4 gain of ≥ 10 dB occurring after treatment 10. For those 57/140 (41%) not improved at treatment 10, 7/26 (27%) with 10 treatments and 12/31 (39%) with > 10 treatments were improved at six weeks post-treatment with 5/7 (71%) and 8/12 (67%) of the 10 and > 10 groups respectively having ≥ 10 dB gain in PTA4 occurring after treatment 10. Overall, there was no significant difference in mean (SD) hearing gain from treatment 10 to six weeks post treatment between the 10 treatments and > 10 treatments groups: 4.73 (8.90) versus 5.93 (11.25) dB, P = 0.53.
Conclusions: In conjunction with steroids, 10 treatments of hyperbaric oxygen therapy appear to offer equivalent benefit to > 10 treatments. Similar improvements in PTA4 and hearing recovery occur after 10 HBOT treatments independent of ongoing HBOT. A prospective trial comparing 10 versus > 10 treatments for ISSNHL with outcome measured beyond treatment completion is warranted.

Published: December 2024

Early identification and prediction of chronic pain in patients after total knee arthroplasty can significantly impact treatment strategies and improve patient satisfaction. This study introduces an innovative artificial intelligence model that predicts pain levels and pain evolution after TKA, empowering surgeons with insights for personalized patient care.

The pain intensity was measured with a visual analog scale on a mobile application, from 1650 knee arthroplasty patients from one week before surgery and up to 12 weeks after surgery. A training set was first used to identify patterns in the data that could best approximate pain trajectories. Out-of-sample pain trajectories were predicted by estimating pattern weights and reconstructing the remaining timepoints. Confidence intervals were calculated to determine prediction accuracy.

The model's accuracy was evaluated based on the percentage of predictions falling within 10 % of the true pain values. With an observation time of up to week 2, the model achieved 67% accuracy in forecasting pain levels for the next 4 weeks, and 61% accuracy for the next 10 weeks. By extending the observation time to week 4, the accuracy improved to 84% and 69% respectively.

The artificial intelligence model showed promising results in predicting pain evolution. By utilizing this model, surgeon teams can manage patient expectations and tailor pain management strategies. The model's predictions facilitate efficient tele- monitoring, enabling remote patient monitoring of patient with less good evolution prediction, reducing the need for frequent clinic visits. Incorporating this technology into surgical practice can enhance surgical outcomes and patient satisfaction.

Published: December 2024

Three-dimensional printing technology has been developed and applied in orthopedic surgery, including knee arthroplasty. To match individual knee morphology, surgeons can choose between standardized implants or customized 3D-printed ones. Despite technical advancements, the routine adoption of 3D-printed implants faces slow progress and various barriers. Our study explores surgeons' perspectives on 3D-printed prostheses by inviting them to freely express their thoughts by answering the question “What do you think about the manufacture of a prosthesis by 3D printing?

The questionnaire was completed by 90 surgeons, with an average experience exceeding 10 years (57.8% ± 10.2%). The majority worked in public hospitals (60% ± 10.1%) and performed zero to 100 prostheses annually (66.7% ± 9.7%). A large proportion do not use planning software (52.2% ± 9.7%), navigation systems, or robots (68.9% ± 9.6%). Respondents collectively agreed on the additional surgical time necessitated by technological innovation (74.4% ± 9.0%). Opinions on 3D printing were diverse, with 70%± 9.5% expressing positivity and 30%± 9.5% holding negative views. Motivations were categorized into seven domains, centered around "pre-surgery" and "post-surgery" concerns. Notably, results showed that a favorable disposition towards 3D printing was associated with the use of navigation systems or robots.

In conclusion, while no outright opposition to implementation was found, some surgeons expressed a preference for validated results and raised concerns about the entire supply chain, encompassing hospitals, insurance companies, and manufacturers. Despite the absence of opposition, the full adoption of 3D printing in joint replacement hinges on advancements across various areas of joint surgery.
3D ultrasound-based strain assessment of the knee medial collateral ligaments: A Novel In-Silico Optimization and validation platform
Authors: Milakovic Lucas , Ingram Marcus , D'hooge Jan , Scheys Lennart
Published: December 2024

This paper introduces a novel in-silico platform for designing, optimizing and validating 3D ultrasound speckle-tracking algorithms that target the biomechanical characterization of knee collateral ligaments. The platform is based on a numerical model of a cadaveric knee following knee arthroplasty (TKA) with a posterior stabilized implant and with experimentally obtained subject-specific material properties of knee collateral ligaments. Applying the platform to develop a 3D ultrasound speckle-tracking algorithm shows promise as the resulting algorithm is capable to capture subtle deformations and strain patterns, with root mean square errors of 0.10 and 0.72 for maximal and minimal principal strains, respectively. However, optimization and in-silico validation are currently limited to one specimen and loading scenario, necessitating further research. Nevertheless, this work lays the foundation for advancing ultrasound-based biomechanical assessments from 2D to 3D, particularly in knee arthroplasty, with the potential for broader clinical impact on musculoskeletal health assessments.
SSPC: A new topological metric for deep learning based anatomical reconstruction evaluation
Authors: Mabrouk Lhoussein Axel , Bertrand Fabrice , Boux de Casson François , Daviller Clément
Published: December 2024

Computer-assisted surgery relies on precise labeling of patient anatomy using 3D images. Major part of this process is nowadays performed by deep-learning (DL) algorithms. However, the evaluation of automated segmentations using conventional metrics like Dice coefficient or Hausdorff distance has limitations, especially when assessing non-significant errors at the mesh level. To overcome this, we propose a novel metric (SSPC) focusing on significant surface disparities to enhance evaluation accuracy.
Practicality of Conducting a Randomized Controlled Trial to Identify Differences in Revision Risk Between Conventional and Technology-Assisted Total Knee Arthroplasty Procedures in a Patient Population at Elevated Risk of Revision – A Simulation Study
Authors: Hickey Matthew , Masri Bassam , Anglin Carolyn , Hodgson Antony J.
Published: December 2024

Given evidence that patients with a lower age at index surgery and higher BMI have an enhanced risk of aseptic revision. In this study we used a previously developed methodology to estimate how large a comparative study would need to be to detect differences between navigated/robotic TKA and conventional TKA in both higher- and lower-risk patient populations, and how long the follow-up periods would need to be to be sufficiently powered to detect those differences.

We modeled and simulated the likely outcomes of potential RCT study designs according to our previously published method. We generated three large sets of patients with distributions of patient-specific factors characteristic of patients at a reduced or enhanced risk of aseptic revision (relative to the typical risk assumed in our previous study). We then computed the corresponding Kaplan-Meier survival curves and applied a log-rank test to each study for statistical differences in revision rates at concurrent follow-up timepoints.

The results from our simulation found survivorship differences favoring TA-TKA ranging from 2.8% to 3.9% at 15- and 20-years follow-up on the patient population at an enhanced risk of aseptic revision. Even for the patient population at the highest baseline risk of aseptic revision, comparative studies would still need to enroll at least 1750 patients in each arm of the study to have an 80% chance of showing this reduction in revision rates at 15 years of follow-up. Traditional RCT studies would require impractically large numbers of patients to be enrolled and excessively long follow-up times to demonstrate whether such a reduction actually exists.
Potential for Reducing Radiation Dose in Proximal Tibia Plate Fixation Using Depth Camera Augmented Fluoroscopy (DeCAF)
Authors: Ranjbaran Parinaz , Guy Pierre , Stockton David , Hodgson Antony
Published: December 2024

Mobile C-arm x-ray machines are commonly used in orthopaedic trauma surgeries to visualize internal anatomy. However, the use of scouting images to aid C-arm positioning during these procedures can prolong operating time and increase radiation exposure. Our Depth Camera Augmented Fluoroscopy (DeCAF) device is designed to reduce the number of x-ray images needed by overlaying the fluoroscopic images onto a live video of the patient’s surface anatomy. In this study, we demonstrate in a simulated operating room (OR) environment that the DeCAF system has clinically acceptable overlay accuracy (1.3 ± 0.2 mm) and allowed the surgeon to substantially eliminate use of x-rays while fixing proximal tibial plates in acceptable positions without significantly changing the time required (p = 0.72). This justifies proceeding to live clinical evaluations.

Published: December 2024

About 4 % of THA patients suffer from iliopsoas syndrome (IS). Modelling of the iliopsoas muscles is considered to be a reasonable aspect for identification of risk factors for IS. In this study we modelled the m. iliacus and the m. psoas major as separate muscles, consisting of 3 fascicles each. We analysed length and angular change of the fascicles from preoperative to postoperative state in a reference position on a database of 201 Japanese patients that underwent unilateral primary THA, with five of these patients being diagnosed with IS postoperatively. We did not find any correlation between length and angular changes and the appearance of IS. Further investigation is needed to find relevant risk factors for prediction of IS.
Solutions for Lower Limb Misalignment: A Segmentation-Guided Coordinate Regression Approach for Landmark Detection and Automatic Measurement
Authors: Amador Sanchez Sebastian , Van Overschelde Philippe , Lebleu Julien , Pauwels Andries , Servaes Ward , Wiersinga Wanne , Vandemeulebroucke Jef
Published: December 2024

Traditionally, surgeons measure lower limb deformities manually by assessing angles between axes drawn on full lower limb X-rays connecting specific landmarks. This process is considered cumbersome and subject to the surgeon's expertise. Our study aims to alleviate the manual detection of landmarks while enhancing the assessment of lower limb malalignment through an innovative approach that combines coordinate regression and landmark segmentation. While various deep learning solutions exist, our method differs by using landmark segmentation to indicate the possible location of the landmarks; this information is combined with the X-rays to estimate the position of the landmarks via coordinate regression. We named this deep learning architecture segmentation-guided regression.

To address the performance of our proposed approach, we evaluated the detection errors for eight landmarks and measured five malalignment metrics. We also compare our approach against landmark regression and landmark segmentation. While landmark segmentation achieved accurate landmark identification, it faced challenges in malalignment measurement due to incorrectly detected landmarks. On the other hand, regression had no failed detections but exhibited lower landmark detection accuracy. Our segmentation-guided regression showed a balance, ensuring no incorrect landmark detections, improved landmark accuracy, and precise malalignment quantification.

By encouraging the coordinate regression network to focus on specific areas through segmentation guidance, our method positions landmarks more accurately and effectively measures malalignment. Consequently, our approach provides surgeons with a reliable tool for comprehensive lower limb malalignment assessment, combining the strengths of coordinate regression and landmark segmentation.

Published: December 2024

Recent alignment techniques for total knee arthroplasty (TKA) allow the possibility of targeting knee joint laxity goals at the planning stage. In the absence of clear guidance in terms of the definition of these goals, surgeons tend to set-up the laxity goals based on their individual preferences. This retrospective review based on the same knee system and the same surgical technique established that the laxity goals were found to be surgeon specific.

Nouvelles perspectives sur le bien-être culturel : le rôle du tiers secteur en matière de patrimoine culturel
Authors: Paltrinieri Roberta , Allegrini Giulia
Published: December 2024

Cet essai a pour objectif de fournir au débat international les données d'une recherche réalisée par la Fondation École des Biens et Activités Culturelles du ministère italien de la Culture, réalisée en 2021 et 2022, à la suite de la mise en application de la Convention européenne de Faro, adoptée en 2005, mais qui n'a été en vigueur en Italie qu'en 2020. Les données de la recherche donent un aperçu intéressant d'une réalité émergente dans le tiers secteur italien, les « communautés patrimoniales », c'est-à-dire les groupes, associés de manière formelle ou informelle, capables de valoriser et de préserver les biens de l'immense patrimoine culturel matériel et immatériel italien afin de le transmettre aux générations futures. Ces communautés patrimoniales ont pour but de mettre en valeur le riche patrimoine culturel de l’Italie, dont 60 sites reconnus par l’Unesco à ce jour. Le tiers secteur italien a donc la possibilité d'élargir le potentiel de son action dans un domaine différent du domaine traditionnel, la culture, et de devenir une référence mondiale pour les pratiques et les politiques. Les objectifs de l'essai sont cependant beaucoup plus larges que fournir simplement un aperçu de ce qui existe. L'essai vise, en effet, à définir les « communautés patrimoniales » comme de véritables dispositifs pour l'activation de parcours de bien-être culturel. On parle aujourd'hui de welfare mix, de deuxième bien-être, de processus de subsidiarité horizontale, de gouvernance collaborative. Notre proposition est donc d'identifier dans les « communautés patrimoniales » des dispositifs pour innover en matière de pratiques et de politiques de bien-être culturel, lequel apparaît comme l'une des frontières des nouvelles formes de bien-être, après la reconnaissance de la relation fondamentale entre soin et culture de l'Organisation mondiale de la santé en 2019 et la crise pandémique.

Safety behavior is crucial to reducing the potential for ship accidents. Therefore, the research focuses on investigating and finding an empirical model of the influence of safety competence and safety culture on crew safety behavior through safety awareness. The research uses a quantitative approach with survey methods and causal design. The sample was 250 crew members. The research instrument used was a questionnaire designed as a Likert scale with five options for responses. The questionnaire was distributed in Google Form format via the WhatsApp application. The data were analyzed using structural equation modeling (SEM). The research results show that safety competence, safety culture, and safety awareness have a significant effect on safety behavior; safety competence and safety culture have a significant effect on safety awareness; and safety competence and safety culture significantly affect safety behavior through safety awareness. These findings promote a new empirical model of the effect of safety competence and safety culture on crew safety behavior through safety awareness. This new model deserves critical discussion by researchers, academics, and practitioners before being adopted, adapted, or modified for their future work in the future.

Mangosteen peel (Garcinia mangostana) is known for its high concentration of bioactive compounds, particularly flavonoids, which possess various health benefits such as antioxidant, anti-inflammatory, and antimicrobial properties. This study aims to identify and quantify the flavonoid content extracted from mangosteen peels sourced from Mataram, West Nusa Tenggara. Using ethanol as a solvent, the extraction process was carried out through maceration, followed by qualitative and quantitative analysis using Fourier Transform Infrared Spectroscopy (FT-IR). The FTIR analysis confirmed the presence of key functional groups associated with flavonoids, including hydroxyl (-OH), ether (C-O), and aromatic C=C groups. Quantitative analysis revealed a significant flavonoid content. Additionally, the extract showed potential antibacterial properties against Aeromonas hydrophila, suggesting its application as a natural antimicrobial agent.

Published: December 2024

Mud crab (Scylla spp.) aquaculture holds significant potential in supporting food security, economic growth, and ecological balance. This study aims to summarize various findings related to critical factors in mud crab farming, such as feed types, rearing systems, and stocking density, and their impact on productivity, feed conversion ratio (FCR), and economic profitability. The review highlights that trash fish feed at 15% of body weight yields optimal growth and feed efficiency due to its high protein content. Feed diversification, including stingray and janitor fish, offers promising results with reduced costs. Various rearing systems are employed, ranging from cages and earthen ponds to advanced technologies such as Recirculating Aquaculture Systems (RAS). Small bamboo floating cages demonstrate superior outcomes in growth and survival rates (SR). Mangrove habitats significantly enhance crab growth, while silvofishery systems provide a sustainable farming alternative. Optimal stocking density, such as 4 crabs/m², balances growth and production. Additionally, Scylla serrata exhibits the best growth rate compared to other species, particularly males. Innovations like soft-shell farming technology add economic value to the product. Overall, the success of mud crab aquaculture depends on the optimal combination of feed, rearing systems, and environmental management. This review offers strategic insights for developing efficient, sustainable, and economically viable crab farming practices.

La bacteria Pseudomona viridiflava (Burkholder, 1930), causa daño económico en frijol (Phaseolus vulgaris L.), se ha demostrado que puede afectar a más de 50 huéspedes (Saygili et al., 2008), entre los que destacan: alfalfa (Medicago sativa), manzano (Malus pumila var. domestica (Borkh.) CK Schneid.), (Alimi et al., 2011), brócoli (Brassica oleracea L.), entre otros; sin embargo, Origanum vulgare, no hay reporte de algún daño sobre el agave mezcalero (Agave inaequidens K.Koch), una especie aun poco estudiada, en esta investigación se fundamentó en la evaluación de los efectos de la bacteria Pseudomona viridiflava en el proceso de imbibición en semilla de Agave inaequidens, mientras que por otra parte se evaluó la tolerancia de la bacteria a los aceites esenciales de canela (Cinnamomum verum Blume), clavo (Syzygium aromaticum L.) y orégano (Origanum heracleoticum Rchb.), como estudios preliminares para la estrategia de manejo ecológico, orgánico, libre de agroquímico en cultivos afectados por Pseudomona viridiflava, se encontró que la concentración del 25% de aceite de orégano y clavo, fueron eficientes en el desarrollo de la bacteria en condiciones in vitro, mientras que en el proceso de germinación en función a la imbibición de la semilla no hubo reducción en el porcentaje de germinación ni signos de daño por efecto de la bacteria.
A ANARQUIA É A REVOLTA CONTRA AS BASES DA FILOSOFIA POLÍTICA MODERNA
Authors: Augusto Acácio
Published: December 2024

Este ensaio reúne algumas anotações dispersas da relação sobre a anarquia como um ataque mortal às bases da filosofia política moderna. As lutas libertárias contemporâneas no campo das formas de existência como cultura libertária não se fazem submetidas a uma teleologia que aponta para uma esperança futura, mas como forma de se inserir na série finita da vida. A revolta e a insubmissão, como manifestações da ação direta, sempre abrem brechas para a transformação da existência sem, no entanto, garantirem nada além da quebra da série de servidão na qual está a vida moderna. Nesse sentido, não se trata de ser contra ou a favor da ciência política e/ou das diversas formas de saber (científicos ou não), mas de sempre se perguntar se tal ou qual forma de conhecimento aumenta e ou diminui a potência da vida livre.
