Authors: Eggon Aku Philip , Agu P. A.
Published: January 2021

This study examined the effect of peer collaboration learning strategy on Basic Science and technology students’ achievement in Nasarawa state, Nigeria. The study employed non-equivalent group pre-test, post-test quasi experimental design. The population of the study was 638 upper basic school levels. A simple random sampling technique was used to sample 128 students from six co-educational schools within Lafia Local Government Area of Nasarawa State, Nigeria. Two research questions with two correspondent hypotheses guided the study. The instrument used for data collection was Basic Science and Technology Achievement Test (BSTAT) which was pilot tested using Kuder-Richardson (K-R, 20) formula to determine its reliability coefficient and this was found to be 0.99. Descriptive statistics of means and standard deviations were used to answer the research questions and inferential statistics of Analysis of Covariance (ANCOVA) was used to test the hypotheses at 0.05 significant level. The results of the study showed that, Peer Collaboration Learning Strategy enhanced students’ achievement in Basic Science better than Demonstration method. There was a significant difference between the mean achievement scores of students taught Basic Science using peer collaborative learning strategy and those taught using demonstration methods and there was no significant difference between the mean achievement scores of male and female students taught Basic Science and Technology using peer-collaborative learning strategy. The study, therefore, recommended among others that Basic Science and Technology teachers should not only use peer collaborative strategy to teach students the subject matter but should also allow them to interact with one another, so that the students can take charge of how they learn.

Air merupakan unsur yang sangat berperan dalam kehidupan khususnya untuk kehidupan manusia. Bukan hanya karena 80% tubuh manusia terdiri dari air, akan tetapi karena didalam air terdapat unsur mineral yang diperlukan untuk perkembangan dan tumbuh fisik manusia. Kebutuhan air menignkat seiring dengan meningkatnya pertambahan jumlah penduduk, hal ini merupakan masalah yang terjadi pada sebagian daerah yang ada di Indonesia. Proyeksi jumlah penduduk dimaksudkan untuk memperkirakan jumlah penduduk suatu daerah dimasa yang akan dating. Untuk menentukan berapa tingkat pertambahan jumlah penduduk, dapat dihitung dengan menggunakan pendekatanMatematical Method. Secara etimologi kebutuhan berasal dari kata dasar “butuh” yang mempunyai arti perlu, jadi kebutuhan air berarti keperluan air. Sedangkan menurut terminology kata kebutuhan besinonim dengan kata pemakaian, jadi kebutuhan air  dapat diartikan menjadi pemakaian air untuk keperluan hidup seseorang. Kebutuhan air bersih untuk pelayanan domestic merupakan kebutuhan yang sifatnya mendasar (pokok) atau pelayanan kebutuhan yang digunakan untuk keperluan rumah tangga. Pelayanan kebutuhan air bersih untuk pelayanan non domestic seperti: niaga, social, industry dan instansi pemerintahan merupakan kegiatan yang dominan dalam suatu kota yang membutuhkan air dalam jumlah yang cukup besar, sehingga kebutuhan air bersih untuk kegiatan ini perlu dihitung. Agar kita mendapatkan jumlah total kebutuhan non domestic.Water is a very important element in life, especially for human life. Not only because 80% of the human body is made up of water, but because in water there is a mineral element needed for the development and physical growth of humans. The need for water increases along with the increase in population, this is a problem that occurs in some regions in Indonesia. The projected population is intended to estimate the population of a region in the future. To determine the level of population growth, can be calculated using the Matematical Method approach. Etymologically, the need comes from the basic word "need" which has the necessary meaning, so the need for water means the need for water. Whereas according to the terminology the word needs besinonim with the word usage, so the need for water can be interpreted to be the use of water for the needs of one's life. The need for clean water for domestic service is a basic need (basic) or service needs that are used for household needs. The service for clean water needs for non-domestic services such as: commerce, social, industry and government agencies is the dominant activity in a city that needs a large amount of water, so the need for clean water for this activity needs to be calculated. So that we get the total amount of non-domestic needs.
Donación de órganos en Paraguay: una ley para combatir los últimos lugares de américa latina
Authors: Ayala-Servín Nicolás
Published: January 2021

Los estilos de vida y los conocimientos de los profesionales del área de la salud, han aumentado la demanda mundial de trasplantes de órganos según la Organización Mundial de la Salud (OMS)1.

Estudios de Europa indican que los principales factores asociados para la donación son la edad, nivel de estudios, la experiencia previa y las actividades prosociales2.

Un estudio en España señala que los principales factores independientes asociados hacia la donación de órganos con impacto positivo son la información transmitida por profesionales sanitarios, la discusión familiar sobre el tema, el conocimiento del concepto de muerte encefálica, el conocimiento de la actitud de la parejahacia la donación, y de la actitud hacia la donación de sangre3.

En Paraguay, 224 pacientes se encontraron en el 2018 en lista de espera y precisan procedimientos para seguir viviendo4. Se presenta una nueva ley donde se estableció la donación directa a partir de los 18 años, a excepción de aquellas personas que dejen constancia de su inconformidad. La ley se basa en el respeto a la voluntad del donante5.

La OMS fomenta el desarrollo ético de programas de donación y trasplante; garantizando una regulación y supervisión adecuadas, así como un seguimiento de las prácticas y los resultados de la donación y el trasplante1. No se debe olvidar la educación necesaria para eliminar los tabúes relacionados y así colaborar en el proceso de cambio generacional.

Hoy en día, en cualquier parte del mundo, el tema de donación y trasplante es insuficiente y genera múltiples impactos en la vida de la persona, su familia y la sociedad. Lo que podría ir cambiando con una actitud empática, apoyada bajo un gobierno trasparente y un sistema educativo fortalecido en la salud pública de cada país.

Published: January 2021

Pollution is increasing in all forms including the water pollution causing damage to the vulnerable aquatic life. In this study, sampling stations were set up to monitor the level of hydrocarbon pollution in the river systems in two selected rivers in India. We used the Dichloromethane for extraction of the sample and analysis were made using the gas chromatography-flame ionization detector. The average value of total petroleum hydrocarbon in the surface water samples is less than or equal to the standard value by DPR of 10 ml/L. The pollution though moderate and low, still pose threat to humans and aquatic organisms and therefore effort should be made by relevant authorities to entails this menace.

Abstract. We have implemented a new stratospheric ozone model in the European Centre for Medium-Range Weather Forecasts (ECMWF) system, and tested its performance for different timescales, to assess the impact of stratospheric ozone on meteorological fields. We have used the new ozone model to provide prognostic ozone in medium-range and long-range experiments, showing the feasibility of this ozone scheme for a seamless NWP modelling approach. We find that the stratospheric ozone distribution provided by the new scheme in ECMWF forecast experiments is in very good agreement with observations, even for unusual meteorological conditions such as Arctic stratospheric sudden warmings (SSWs) and Antarctic polar vortex events like the vortex split of year 2002. To assess the impact it has on meteorological variables, we have performed experiments in which the prognostic ozone is interactive with radiation. The new scheme provides a realistic ozone field able to improve the description of the stratosphere in the ECMWF system, we find clear reductions of biases in the stratospheric forecast temperature. The seasonality of the Southern Hemisphere polar vortex is also significantly improved when using the new ozone model. In medium-range simulations we also find improvements in high latitude tropospheric winds during the SSW event considered in this study. In long-range simulations the use of the new ozone model leads to an increase in the winter North Atlantic Oscillation (NAO) index correlation, and an increase in the signal to noise ratio over the North Atlantic sector. In our study we show that by improving the description of the stratospheric ozone in the ECMWF system, the stratosphere-tropospheric coupling improves. This highlights the potential benefits of this new ozone model to exploit stratospheric sources of predictability and improve weather predictions over Europe on a range of time scales.

Abstract. New-particle formation (NPF) is a significant source of atmospheric particles, affecting climate and air quality. Understanding the mechanisms involved in urban aerosols is important to develop effective mitigation strategies. However, NPF rates reported in the polluted boundary layer span more than four orders of magnitude and the reasons behind this variability subject of intense scientific debate. Multiple atmospheric vapours have been postulated to participate in NPF, including sulfuric acid, ammonia, amines and organics, but their relative roles remain unclear. We investigated NPF in the CLOUD chamber using mixtures of anthropogenic vapours that simulate polluted boundary layer conditions. We demonstrate that NPF in polluted environments are largely driven by the formation of sulfuric acid-base clusters, stabilized by the presence of amines, high ammonia concentrations and lower temperatures. Aromatic oxidation products, despite their extremely low volatility, play a minor role in NPF in the chosen urban environment but can be important for particle growth and hence for the survival of newly formed particles. Our measurements quantitatively account for NPF in highly diverse urban environments and explain its large observed variability. Such quantitative information obtained under controlled laboratory conditions will help the interpretation of future ambient observations of NPF rates in polluted atmospheres.
Untangling irrigation effects on maize water and heat stress
alleviation using satellite data
Authors: Zhu Peng , Burney Jennifer
Published: January 2021

Abstract. Irrigation has important implications for sustaining global food production, enabling crop water demand to be met even under dry conditions. Added water also cools crop plants through transpiration; irrigation might thus play an important role in a warmer climate by simultaneously moderating water and high temperature stresses. Here we use satellite-derived evapotranspiration estimates, land surface temperature (LST) measurements, and crop phenological stage information from Nebraska maize to quantify how irrigation relieves both water and temperature stresses. Our study shows that, unlike air temperature metrics, satellite-derived LST detects significant irrigation-induced cooling effect, especially during the grain filling period (GFP) of crop growth. This cooling is likely to extend the maize growing season, especially for GFP, likely due to the stronger temperature sensitivity of phenological development during this stage. The analysis also suggests that irrigation not only reduces water and temperature stress but also weakens the response of yield to these stresses. Specifically, temperature stress is significantly weakened for reproductive processes in irrigated crops. The attribution analysis further suggests that water and high temperature stress alleviation contributes to 65 % and 35 % of yield benefit, respectively. Our study underlines the relative importance of high temperature stress alleviation in yield improvement and the necessity of simulating crop surface temperature to better quantify heat stress effects in crop yield models. Finally, untangling irrigation effects on both heat and water stress mitigation has important implications for designing agricultural adaptation strategies under climate change.
Assessing short-term climate change impacts on water supply at the Wupper catchment area, Germany

Published: January 2021

Abstract. The occurrence of dry periods on the Wupper catchment has increased in the last decades in conjunction with the shifting of the precipitation regime. In the frame of the Horizon 2020 project BINGO (Bringing INnovation to onGOing water management), the effects of climate change scenarios on the water cycle in the Wupper catchment area were investigated. To quantify these effects, a set of hydrological models (NASIM and SWAT) has been set-up, calibrated, and validated for the upper part of the Dhünn River catchment area – Wupper River's main tributary. This sub-catchment corresponds to one of the inflows to the Große Dhünn Reservoir (GDR), the second largest drinking water reservoir in Germany. Both models were driven with climate data from decadal predictions, which have been selected instead of IPCC-RCP scenarios, as they provide a more realistic assumption of climate variability for the next 10 years. Ten decadal members based on the MiKlip (Mittelfristige Klimaprognose – medium-term climate prediction) framework have been prepared for the time span of 2015 to 2024. Additionally, a simulation with TALSIM-NG (a reservoir-oriented hydrological model) was carried out to obtain future reservoir storage. Special focus was given to identify observed trends and compare them to future trends. Past hydro-meteorological extreme dry periods were evaluated based on observed data. Standardized Precipitation Index (SPI), Standardized Precipitation-Evapotranspiration Index (SPEI), and Standardized Runoff Index (SRI) were estimated for different seasons to determine if they were abnormally dry or wet. SPI, SPEI, and SRI were also calculated with decadal predictions to evaluate future extreme dry periods. Uncertainties in climate data predictions are one of the greatest challenges. Observed and forecast time series were compared by means of statistical tests in order to assess uncertainties in climate data predictions. Also, the application of two hydrological models aims to determine potential uncertainties, so that predictions are more reliable. Results indicate that SRI might be more appropriate to estimate drought periods for the study area in the frame of reservoir management – where inflow rates are of crucial importance – as this index quantifies losses in runoff formation processes. In terms of inflow rates to GDR, future changes indicate a reduction in runoff for the spring season, while an increment during winter. On the other hand, a clear change in pattern for fall and summer seasons remains uncertain. Simulations of GDR reservoir volume with different climate scenarios show that water stress by the end of 2024 is not unlikely, so sustainable adaptation measures should be further considered. Effectively managing the GDR will become consequently more complex.

Abstract. The anisotropy of magnetic susceptibility (AMS) technique provides an effective way to measure fabrics and in the process, interpret the kinematics of actively deforming orogens. We collected rock fabric data of alluvial fan sediments surrounding the Sierra Nevada massif, Spain, and a broader range of Cenozoic sediments and rocks across the northern Apennine foreland, Italy, to explore the deformation fabrics that contribute to the ongoing discussions of orogenic kinematics. Sierra Nevada is a regional massif in the hinterland of the Betic Cordillera. We recovered nearly identical kinematics regardless of specimen magnetic minerology, structural position, crustal depth, or time. The principal elongation axes are NE-SW in agreement with mineral lineations, regional GPS geodesy, and seismicity results. The axes trends are consistent with the convergence history of the Africa-Eurasia plate boundary. In Italy, we measured AMS fabrics of specimens collected along a NE-SW corridor spanning the transition from crustal shortening to extension in the northern Apennines. Samples have AMS fabrics compatible only with shortening in the Apennine wedge and have locked in penetrative contractional fabrics, even for those samples that were translated into the actively extending domain. In both regions we found that specimens have a low degree of anisotropy and oblate susceptibility ellipsoids that are consistent with tectonic deformation superposed on compaction fabrics. Collectively, these studies demonstrate the novel ways that AMS can be combined with structural, seismic, and GPS geodetic data to resolve orogenic kinematics in space and time.

Published: January 2021

12 January 2018 The objectives of the Year 1 Pilot Study were to (i) develop a methodology for determining tornado occurrence in Northern Ontario, and (ii) obtain research quality data for at least one event. Because of the isolation of many regions, the approach assumed the use of radar data analysis combined with aerial surveys. These objectives were achieved. Aerial surveys were conducted for a total of seven events in Ontario and southern Quebec and 15 confirmed or probable tornadoes identified. Archival geo-tagged imagery was obtained for six of these events. Ten confirmed or probable tornadoes were identified in Ontario, five of which were not in the OSPC database. In addition, 5 tornadoes were confirmed in Quebec. For the 2017 season, the OSPC had a list of 10 verified tornadoes, as of December 21, 2017. The pilot project raises this number to 15. In total, 4 EF2 tornadoes and 1 EF3 tornado were identified via aerial photography. The remainder were EF1 or EF0. UPDATE – 23 April 2018 Based on the analysis of newly available Planet.com high-resolution satellite imagery and related tools, several events were reassessed and a number of additional tornadoes were discovered. Overall, an additional three tornadoes were added to 2017 count. The updated events are listed in a revised 2017 summary table appended at the end of this document.

O AMOR X O ÓDIO: A ATUALIDADE DO PENSAMENTO DE PAULO FREIRE E O DESASSOSSEGO DOS NEOFASCISTAS NO BRASIL
Authors: Gehlen Maria Eloá
Published: January 2021

Este trabalho reflete a atualidade do pensamento de Paulo Freire e a contraposição ao movimento neofascista no Brasil no século XXI. Por que tanto ódio quando as palavras de Freire conduzem ao amor? O objetivo é clarear os desassossegos que os conceitos, ideias, obras e práticas educacionais de Freire provocam nos seus opositores de extrema-direita. A metodologia consiste em duas histórias de vida com uma professora Freireana e com um cidadão que apoiou o fascismo italiano quando jovem e que, hoje, vive no Brasil. Também foi efetuada uma revisão bibliográfica. Os resultados apontam ao desconhecimento da obra desse educador brasileiro por quem o critica, assim como o descortinar de pessoas que se identificam com ideais fascistas como quem se sente inferiorizado intelectualmente e, assim, cultiva o ódio. Um fator que traz esperança é o surgimento de movimentos antifascistas, responsáveis por manifestações públicas de movimentos sociais populares e do movimento Antifa.
Subcutaneous versus intravenous tramadol for extremities injuries with moderate pain in the Emergency Department: A randomized controlled non-inferiority trial
Authors: Subramaniam Thayaharans , Bustam Aidawati
Published: January 2021

Background: Pain is a leading cause of visits to any emergency department (ED) and a large percentage of it is primarily caused by musculoskeletal trauma, however there has been a lack of use of analgesia in a large proportion of these patients. Tramadol is a common choice among emergency residents due to the rare incidence of respiratory depression during its administration, low incidence of cardiac depression, and the incidence of dizziness and drowsiness is lower than when morphine is administered. We aim to determine whether subcutaneous tramadol administration has a lower incidence of adverse events and pain score associated with administration in comparison to intravenous tramadol. Methods: Single-center randomized parallel group trial of subcutaneous (S/C) versus intravenous (IV) tramadol as analgesia for extremities injuries with moderate pain. Both groups received a single dose of 50 mg tramadol and reassessed at 15, 30, 45, 60 minutes. Results: A total of 232 patients were studied, and divided into group A (IV tramadol) and group B (S/C) (). There was higher incidence of adverse events in the IV group at 0, 15 and 30 minutes of administration and higher mean pain score associated with administration in the IV group. These adverse effects include nausea, vomiting, giddiness, dizziness, and allergic reactions. The total number of patients developing adverse effects was 34 of 112 patients in the intravenous group as compared to 14 of 120 patients in the subcutaneous group (). Conclusion: S/C tramadol has less adverse effects and causes less pain as compared to IV tramadol in managing moderate pain with extremities injuries and could be considered for pain relief in mass casualty incidents.

Published: January 2021

Background: Cardiovascular disease is the number one killer in Qatar. Cardiac rehabilitation (CR) is a secondary prevention model of care for cardiac patients. It is well-documented that CR reduces cardiovascular morbidity and mortality by 20%. However, CR is underutilized worldwide, with low enrolment and adherence rates. This study aims to investigate factors associated with enrolment and adherence, and to examine the relationship between adherence and change in cardiac risk factors. Methods: There were 714 cardiac patients, aged ≥ 18 years, referred to a CR program in Qatar. Retrospective cohort study using data from (January 2013-September 2018) were analyzed. Logistic regression models were used to assess factors associated with enrolment, adherence, and predictors of adherence. A paired sample t-test was used to identify mean change in cardiac risk factors: body mass index, low-density lipoprotein, high-density lipoprotein and total cholesterol) pre/post-CR. An independent sample t-test was used to identify change between groups (adherents vs. non-adherents). Results: The majority of our patients were males (n = 641, 89.8%) and non-Qatari (n = 596, 83.5%), i.e., similar to the Qatar population profile of 75% males and 15% Qatari, one fourth were smokers (n = 185, 25.91%), and one fifth (n = 128, 18.8%) were diagnosed with severe depression. Significant patient factors positively associated with enrolment (p < 0.05) were nationality, percutaneous coronary intervention (PCI), coronary artery bypass grafting, and coronary artery disease (). The number of sessions attended by patients is shown in . Patients with American Association of Cardiovascular and Pulmonary Rehabilitation (AACVPR) moderate and high-risk levels were more likely to adhere compared to those with low risk. Percutaneous coronary intervention (PCI) and musculoskeletal disease were negatively associated with adherence (). We found clinically significant health improvements among adherents compared to non-adherents; reduction of 10% in cholesterol, and 15% in LDL (low-density lipoprotein). Conclusion: This study provides new insights into the factors that lead patients to enrol in and adhere to CR in the Qatar setting. These factors represent opportunities for targeted interventions to improve CR utilization.

Background: The ‘Act FAST’ campaign is a major international stroke prevention program aiming to raise knowledge and awareness of stroke signs and symptoms and encouraging calling emergency medical service (EMS) providers as soon as symptoms are recognized. We aim to evaluate the impact of the campaign by analyzing EMS stroke calls in Qatar as studies on the impact of such initiative on behavioral response at onset are limited. Methods: This is a retrospective time series evaluation utilizing monthly Hamad Medical Corporation (HMC) EMS call data for strokes in Qatar. HMC Ambulance Service (HMCAS) uses the Medical Priority Dispatch System (MPDS) and International Academies of Emergency Dispatch (IAED) protocols. Emergency calls are thoroughly analyzed for stroke diagnosis. We will evaluate pre- and post-campaign the relative change in stroke calls volume and classify them into true stroke and stroke mimic calls based on Emergency Department and Stroke Unit data, and make a comparison in total proportion of true stroke calls. We will perform multivariable regression to measure the effect of campaign exposure on the volume of stroke-related calls and also describe any significant association between specific patient characteristics with increased ambulance usage, after controlling for confounders. Anticipated results: Following the signs and symptoms of the stroke awareness campaign and suggested behavioral response at stroke onset, a relative increase in the number of stroke calls to EMS is expected as reported by Bray et al., following a similar campaign in Australia. Conclusion: The impact of the Act FAST stroke campaign on the population of Qatar will be determined by evaluating a relative change in stroke calls post-campaign and misclassifications. The percentage change in false alarms and calls without stroke specific symptoms in a population group will help identify campaign related contributing factors thereby providing evidence to tailor future campaigns.

Published: January 2021

Background: Experiential learning is the backbone of many healthcare professional education programs, and the quality of experiential learning is dependent on the skills, experiences, and proficiency of the clinical preceptors who largely contribute to this experience. Preceptors should ideally possess both clinical practice and teaching skills; however, preceptors often do not possess formal training as educators. This research was conducted at Qatar University with the aims of identifying preceptors’ educational needs and developing the skills by designing an educational professional development program called: “The Practice Educators’ Academy”. Methods: A mixed-methods triangulation study design was applied to identify preceptors’ educational needs quantitatively through a validated survey sent to preceptors (n = 325), and qualitatively by conducting 11 focus groups with preceptors (n = 20), students (n = 42), and clinical faculty members (n = 7). Quantitative and qualitative data in addition to an extensive literature review were used in designing the academy by an inter-professional healthcare and educational team. Results: Principles of learning theories, planning for experiential learning, teaching strategies, students’ assessment and feedback, and communication skills for effective preceptorship and conflict resolution were the key domains expressed as preceptors’ educational needs. A five-module program syllabus was designed to meet these needs while benchmarking it with international preceptors’ educational development programs to achieve generalizability. The designed syllabus was critically examined and validated by national and international health professional education scholars. demonstrates the validated syllabus. Conclusion: “The Practice Educators’ Academy” syllabus is the first intervention nationally and regionally for preceptors to be better equipped with skills and knowledge required for their role as clinical educators, which will enrich the internship experiences of students. With that, preceptors can better prepare competent health profession graduates that will advance healthcare outcomes and meet the healthcare needs of Qatar society and ultimately contribute to achieving Qatar National Vision 2030.

Background: Point-of-care testing (POCT) facilitates rapid decisions by performing tests near or at the patient side. POCT integration accelerates clinical decisions and enhances patients’ standard of care in emergency settings. POCT positively influences patient care especially during life-threatening situations or in the operating rooms and critical care areas as it enables the rapid provision of information related to blood gases and electrolytes. Such a process reduces Therapeutic Turnaround Time (TTAT) and pre-analytic and post-analytic testing errors . Methods: POCT has been implemented across Hamad Medical Corporation (HMC) Emergency Departments and Critical Care Units in line with applicable hospital regulations and accreditation requirements. The aim of this project was to standardize blood gas analyzer methods and processes over all HMC facilities. The POCT team worked according to the College of American Pathologists (CAP) standards and regulations and selected the most advanced technologies available on the market for integration of the equipment on the HMC network while enabling for remote-access. This has been achieved by ensuring full connectivity integration to the hospitals Laboratory Information System (LIS). Training programs have been conducted to ensure that only competent and certified staff are authorized to perform patient testing in the Emergency Departments and Critical Care Units . Results: A total of 80 blood gas analyzers have been installed including 47 analyzers in Emergency Departments and Critical Care Units. During the period from August 2018 up to August 2019, 179,659 tests were performed by 3123 different operators including nurses, respiratory therapists, and perfusionists. The POCT system detects, troubleshoots, and minimizes errors by continuous monitoring of Quality Key Indicators (QKI). Conclusion: Successful implementation of POCT for blood gas analysis enabled rapid, accurate, and cost-effective patient testing. Furthermore, POCT of blood gases in emergency areas has reduced process complexity and improved operational workflow and led to an enhanced lean process. Effective communication through electronic documentation, quality assessment, and ongoing monitoring by the POCT team in parallel with healthcare providers who are performing bedside POCT will achieve compliance with international standards for emergency and critical care areas.

Estudio desde las distintas perspectivas de comprensión de las políticas de vigilancia y control social de la vida al enfocar la actual pandemia. Se enfatiza que todas esas políticas se aplican hoy mediante las TIC, extendiendo el dominio digital sobre el mundo offline y transformando la pandemia en tecnopandemia. Así resultan todas ellas, biopolítica, teoría de la excepción y psicopolítica, conceptualmente superadas por la tecnopolítica. La tecnopolítica es la forma político-social de la vida onlife, la práctica de un poder infodémico, que utiliza tecno-personas, que no son ni individuos ni tampoco sujetos políticos, para controlar y someter la vida offlife.
La Transeducación como una expresión del futuro de la educación
Authors: Díaz Fernández José Alfredo
Published: January 2021

El artículo tiene por objetivo cuestionar la institucionalidad educativa y los nuevos actores que van transformando la relación enseñanza/aprendizaje, su potencialidad democrática y los saberes adecuados para la actualidad y el futuro próximo. Esto se realiza, a través de una discusión con el Transhumanismo y el Capitalismo Cognitivo, analizando los riesgos y las posibilidades pedagógicas y normativas que abren estas transformaciones. Además, por el examen de las perspectivas epistemológicas-educativas decoloniales y transmodernas, que buscan movilizar contenidos y formas de reflexión democráticas, emancipadoras y alternativas para la construcción de otros futuros de la educación, que denominamos transeducación.
La parresia de Jesús como constituyente del “héroe filosófico”.
Authors: Olivares Benjamín Nicolás
Published: January 2021

El presente trabajo consta de tres partes esenciales que tienen como objetivo identificar y describir una parrhesia auténtica en Jesús, a la luz de los cursos dictados por Michel Foucault en el Collège de France. La primera y segunda parte se centran una caracterización,contrastación e indagación de las nociones elementales que constituyen los discursos de verdad en el ministerio de Jesús. En la tercera y última parte presento un acercamiento de Jesús con Diógenes y Sócrates,y cómo ciertos elementos de la presencia de la parrhesia cínica presentes en Jesús posibilitan la idea de Jesús como un "héroe filosófico".
