Solving Problems of Plant Physiology during Periods of Confinement or Online University Education
Authors: Molina M. Carmen , Palomino Javier , Costilla-Legaz Regina
Published: September 2023

Plant Physiology and Ecophysiology (PPE) is a subject taught in the biology degree. One of the skills that students must acquire is “the ability to solve PPE problems.” Acquiring this competence requires a precise working methodology, a high degree of presence, and teamwork between teachers and students. Because of the COVID-19 pandemic and health restrictions, we had to teach the class online. This article shows the learning methodology we employed using information and communication technologies (ICTs) for the achievement of this competence. We also analyzed the results obtained in the academic performance of the students in comparison with previous years in which the classes were face-to-face. The results confirmed that the students obtained this subject-specific competence through the ICT teaching process compared to face-to-face teaching. The study also revealed that online assessment services are not secure as they do not appear to prevent cheating behavior. Therefore, we propose this learning methodology for future online teaching activities although improvements in the evaluation process must be addressed.
An Authentic Demonstration of the Mark–Recapture Technique Using Ant Colonies
Authors: Haney Brian
Published: September 2023

The mark–recapture technique paired with the Lincoln–Peterson index is a commonly used method of estimating the size of animal populations in ecological research. However, this technique is difficult to emulate in an educational setting due to the logistical constraints inherent to the process of capturing and marking live animals. As a result, most lessons on mark–recapture use captive animals or inanimate objects as the focal population. This approach may give students an inaccurate understanding of the potential applications and limitations of the mark–recapture technique. Here, we describe an authentic application of the mark–recapture technique that allows students to gain hands-on experience with the method on naturally occurring ant colonies, a ubiquitous animal system. By participating in this lesson, students will directly engage with the mark–recapture technique to estimate the number of individuals within ant colonies and will learn about the natural history of ants in the process.
Using Ruminant Livestock as a Post-Secondary Model to Introduce Microbial Ecology and Systems Biology
Authors: Gomez Noe A.
Published: September 2023

Ruminant animals serve as an excellent platform for post-secondary biological science instructors to teach microbial ecology and systems biology. Instructors can extrapolate the dynamic interactions that microorganisms play in modifying the diet of a ruminant animal. This symbiosis can be used to teach how ruminants can thrive on low-quality feed yet produce high-quality substances such as meat and milk. Instructors can require students to create graphical models that represent these dynamics, through the lens of systems biology. Altogether, instructors should consider teaching microbiology in their introductory biological science courses through the lens of ruminant production; especially, since we live in a time when vast population interest revolves around the origins of our food.
Molecular mechanisms of TWIST1‐regulated transcription in EMT and cancer metastasis

Published: September 2023

TWIST1 induces epithelial‐to‐mesenchymal transition (EMT) to drive cancer metastasis. It is yet unclear what determines TWIST1 functions to activate or repress transcription. We found that the TWIST1 N‐terminus antagonizes TWIST1‐regulated gene expression, cancer growth and metastasis. TWIST1 interacts with both the NuRD complex and the NuA4/TIP60 complex (TIP60‐Com) via its N‐terminus. Non‐acetylated TWIST1‐K73/76 selectively interacts with and recruits NuRD to repress epithelial target gene transcription. Diacetylated TWIST1‐acK73/76 binds BRD8, a component of TIP60‐Com that also binds histone H4‐acK5/8, to recruit TIP60‐Com to activate mesenchymal target genes and MYC. Knockdown of BRD8 abolishes TWIST1 and TIP60‐Com interaction and TIP60‐Com recruitment to TWIST1‐activated genes, resulting in decreasing TWIST1‐activated target gene expression and cancer metastasis. Both TWIST1/NuRD and TWIST1/TIP60‐Com complexes are required for TWIST1 to promote EMT, proliferation, and metastasis at full capacity. Therefore, the diacetylation status of TWIST1‐K73/76 dictates whether TWIST1 interacts either with NuRD to repress epithelial genes, or with TIP60‐Com to activate mesenchymal genes and MYC. Since BRD8 is essential for TWIST1‐acK73/76 and TIP60‐Com interaction, targeting BRD8 could be a means to inhibit TWIST1‐activated gene expression.

Analysis of the thermal shock and fouling resistance of the Kalimantan zircon based hybrid composite ceramic coating in boiler environment
Authors: Lestari Yulinda , Zulfia Anne , Ardin Muhammad , Chandra Septian Adi , Widyawati Fauzi , Mabruri Efendi
Published: September 2023

Power plant boilers operate at relatively high temperatures and pressures. As they are prone to material degradation, fouling and scaling, the materials used must have good thermal and chemical resistance. Coating material is one of the solutions to problems that exist in boilers. In this study, the basic coating material used came from local mineral resources, namely Kalimantan zircon sand and zirconia that had been purified from zircon sand. And there is the addition of filler as a coating reinforcement so that the coating properties become better. The variables of this study are variations of filler materials that have lubricating properties such as hBN, MoS2, graphite and a mixture of the three fillers (hybrid). The coating method used is slurry spray coating and then sintering at 600 °C. The main coating parameter tests carried out were thermal shock and anti-fouling resistance. From the research results, it was found that the purification of Zircon Sand resulted in an increase in Zirconia content from 59 % to 68 %. From the results of the thermal shock resistance and anti-fouling tests, it was found that the coating with purified zircon has better thermal shock resistance while the fouling resistance is not significantly different from unrefined zircon sand, so it is necessary to develop a zircon purification process to obtain a higher ZrO2 content. For filler variations, the hybrid filler produces a coating with better thermal shock and anti-fouling resistance so that it can be used for optimizing ceramic composite coatings

Published: September 2023

The formation of a differentiated structure of the arable horizon during the pre-sowing processing of the grant is a relevant task that can be solved by designing appropriate soil-processing technical means.
A scientific hypothesis has been put forward, according to which increasing the efficiency of the process of forming a differentiated structure of the arable horizon can be achieved by improving the design and substantiating the structural and technological parameters of the tillage module for pre-sowing tillage. Numerical simulation was carried out in the Simcenter STAR-CCM+ software package using the Lagrangian multiphase model employing the discrete element method. Calculation of second-order regression equations and statistical processing of the obtained data was carried out in the Wolfram Cloud software package.
As a result of the simulation of the improved design of the tillage module, which includes one drum, plowshare, casing, and cleaner, it was found that it performs the operation of separation and redistribution of soil aggregates with almost the same efficiency as the basic design with 2 drums and plowshare.
As a result of the simulation of the work process of the improved tillage module, regression equations of the content of the 10–30 mm fraction in the 0–4 cm soil layer and the content of the 0–10 mm fraction in the 4–8 cm soil layer from the research factors were obtained. The chosen factors of influence were a casing outlet clearance, casing inlet clearance angle, cleaner inclination angle, drum rotation frequency, unit movement speed, and processing depth. Solving the problem of multi-criteria optimization, the rational structural and technological parameters of the tillage module for pre-sowing tillage were calculated
Determining the frequency of transverse oscillations of an elastically fixed disk of a circular saw
Authors: Dziuba Lidiia , Chmyr Oksana , Menshykova Olha , Lishchynska Khrystyna
Published: September 2023

The object of the study is a circular saw blade. An annular plate of constant thickness with a free outer contour and a fixed inner contour was taken as the calculation scheme of the saw blade. The real conditions for fixing the internal circuit correspond to the elastic fixing of the saw blade with clamping flanges on the shaft of the machine. For the accepted calculation scheme of the circular saw, the dynamic model was a fourth-order nonlinear differential equation of the transverse oscillations of the annular plate with the corresponding boundary conditions. The rotation of the circular saw was taken into account in the dynamic model due to the radial force in the middle surface of the ring plate. This force arises as a result of the action of centrifugal forces during the rotation of the saw blade. The solution to the fourth-order nonlinear differential equation was constructed using the Bubnov-Galyorkin numerical method. The boundary conditions for constructing the solution were as follows: the outer contour of the saw disk was considered free; the inner contour of the saw disk – elastically fixed with a certain stiffness coefficient.
The solution was implemented in the Maple 15 mathematical environment in the form of a developed program. According to the obtained frequency equation, the values of cyclic and natural frequencies of transverse oscillations of circular saw disks of different thicknesses with the same radius of the inner contour and three values of the radii of the outer contour were determined: 150 mm, 200 m, and 250 mm. The effect of the rigidity of the internal contour fixing and the angular speed of rotation of the saw blade on the natural frequencies of transverse oscillations was studied. The study was performed for saw disks in the case of oscillations with one, two, and three nodal diameters. It was established that the rigidity of the internal contour of the saw blade has the greatest influence on the natural frequency of transverse oscillations with one nodal diameter
Revealing patterns in the stressed-strained state of load-bearing structures in special rolling stock to further improve them
Authors: Koshel Oleksii , Sapronova Svitlana , Kara Serhii
Published: September 2023

The object of research is strength indicators of load-bearing structures of special rolling stock (dump cars). The research problem is the appearance of the same type of cracks in the girder beams of dump cars, the repair of which is not provided for by the current repair documentation. Malfunction analysis, control tests, strength studies by calculation and experiment were carried out.
The analysis of malfunctions of cars in operation helped prove the place of occurrence of fatigue defects – the girder beam. This made it possible to determine specific zones of load-bearing elements, in which during control tests of cars, on the basis of taking into account data on fatigue defects, it is necessary to measure stress parameters.
The results of the control tests showed that the lowest value of the fatigue resistance reserve factor n=1.6 for the dump car is found in the zone on the girder beam in the area of the pivot beam. The value of n is within acceptable limits.
Normative calculations were carried out and a separate calculation (emergency) mode was additionally defined in the SolidWorks Simulation 2019 software package (France). Based on the results of the dump car stress calculations, it was established that the maximum equivalent stresses in the load-bearing structures of the car occur during its unloading due to twisting, and the stress vectors are at an angle of 45°. During the calculation of individual load modes, the stresses exceed the permissible values.
In order to ensure the necessary strength conditions, it is proposed to introduce a reinforcing pad into the girder beam of the dump car, due to which the calculated stresses are within the permissible limits.
The research will contribute to devising the recommendations for the restoration of dump cars, for designing modern structures of special rolling stock, and for improving strength determination processes

The object of the study is the dynamics of air ion spread in rooms from the source of artificial air ionization under different starting conditions. There is currently the problem of distribution of air ions in the room with regulatory concentrations in all critical zones. An effective method of ensuring proper air ion concentrations is to model their propagation from ionization sources. Existing approaches to calculating the dynamics of air ions of both polarities have been improved in this study. Unlike known solutions, the impact on their concentration of electrostatic field and the interaction of air ions with suspended particles was taken into account.
A model of air ion propagation in rooms with artificial air ionization and the principles of its numerical modeling was built. The use of Laplace Equation in the aerodynamic model instead of the Navier-Stokes equation for the potential of the flow rate has made it possible to design an "Ion 3D" tool, which reduces the time of implementation of one scenario from several hours to 7 seconds. Modeling of the propagation of air ions of both polarities in the room under different initial conditions was carried out. Two-dimensional and three-dimensional models with their visualization was implemented. The peculiarity of the resulting models is that they make it possible to determine the concentrations of air ions in any section of the room by three coordinates. Given this, the rapid selection of the variants of the source data makes it possible to achieve the normative values of concentrations of air ions in the area of breathing – exceeding 500 cm-3 of each polarity. Simulation makes it possible to design a room in which, under the condition of artificial ionization of air, the concentrations of air ions close to the optimal values of 3000–5000 cm-3 are provided
Improving the efficiency of calcium hydrocarbonate removal and reducing water hardness through discrete pulse energy input
Authors: Obodovych Oleksandr , Sablii Larysa , Sydorenko Vitalii , Tselen Bogdan
Published: September 2023

For municipal water supply systems, industrial enterprises, and thermal plants, the content of mineral impurities in water is regulated, which necessitates the use of technologies for their removal.
The object of study was water from an artesian well, which was treated on a rotor-pulsation apparatus that implements the principle of discrete-pulse energy input in an aeration-oxidizing setup of rotor type.
The effect of the principle of discrete-pulse energy input on the process of extracting calcium bicarbonate from water to reduce its hardness is studied.
It was determined that when treating water in the rotor-pulsation apparatus without adding ammonium hydroxide solution, it is possible to reduce the calcium ions concentration from 77.1 to 57.1 mg/L, and the total hardness from 13.4 to 7.6 mmol/L. It has been proven that the addition of 0.1 wt.% ammonium hydroxide to the treated water and treatment in the rotor-pulsation apparatus at the flow shear rate of 40·103 s-1 during 10 cycles allows for to reduce in the calcium ions concentration by 99.3 % and to reduce the total hardness to 0.16 mmol/L.
This is explained by the formation of a water-air mixture, which, passing through the rotor-pulsation apparatus, is affected by shock waves, interphase turbulence, microcavitation, and vortices, which leads to an increase in the rate of mass transfer of oxygen from the gas phase to the liquid and its transportation by the liquid. At the same time, the structure of water changes with the formation of free hydrogen bonds, which causes its increased activity and reactive capacity.
Water treatment according to the principle discrete-pulse energy input in the rotor-pulsation apparatus is recommended for use in the implementation of a number of chemical softening methods to reduce the consumption of reagents and increase the degree of purification

Published: September 2023

This paper reports the analysis of fire resistance assessment methods of building structures. Based on the results, it was established that conducting fire tests is not expedient and harmful to the environment. The use of estimation fire resistance assessment methods for reinforced concrete staircases is not considered possible due to the lack of appropriate tables with fire resistance classes for the tabular method. The use of the estimation zone method is also impossible because of the lack of temperature nomograms of temperature distribution during exposure to the standard fire temperature regime. There are also no described procedures for applying the estimation refined method for reinforced concrete staircases. So, using mathematical models, the existing type of reinforced concrete staircase was reproduced. Employing the finite-element method, the behavior of reinforced concrete stairwells under the influence of fire was investigated.
Based on the results of these experiments, it was analyzed which structural geometric parameters of reinforced concrete stairwells have the greatest influence on their fire resistance. In this way, three independent, most significant geometric parameters of reinforced concrete stairwells were established – the height of the solid base, the thickness of the protective layer of the lower row of reinforcing bars, and the length of the span.
Therefore, the ranges of the most significant structural geometric parameters of reinforced concrete stairwells were used to build a regression dependence of the fire resistance limit on these parameters in order to design a full factorial numerical experiment.
After proving the adequacy of the results obtained according to the regression dependence, tables were constructed with the geometric parameters of reinforced concrete stairwells to determine the compliance of these structures with the required fire resistance class. The use of these tables will make it possible to reduce the risks of threats to human life and health during a fire by determining the possibility of using these structures with a guaranteed fire resistance class during design

Published: September 2023

The aim of the work – study the uroantiseptic activity of a complex of glycosides of phenolic compounds from lingonberry leaves in a complex with the amino acid arginine.
Materials and methods. The object of the study was a phytosubstance, which is a complex of glycosides of phenolic compounds from lingonberry leaves in combination with the amino acid arginine (CGPA). Female laboratory rats were given a cleansing enema twice, after which the rats were provided with adequate sedation by injecting IV XYLA 2 % for anesthesia, then rectally injected 1000 μl of Escherichia coli strain at a concentration of 109 CFU/ml. The next day after infection, the animals were subjected to cryogenic action - acute cold stress at a temperature of 0+2 °C for 2.5 hours, promoting the development of the infectious and inflammatory process. The uroantiseptic effect was studied according to the following parameters: the number of leukocytes in the urine, the number of colony-forming microorganisms E.coli in 1 ml of urine (CFU/ml).
Results. According to the obtained results of the experiment, it was established that the complex of glycosides of phenolic compounds from the leaves of lingonberry in a complex with the amino acid arginine (CGPA) showed a high uroantiseptic effect in the experimental treatment of urinary tract infection caused by E. coli ATCC 25922, which was manifested in the sanitation of the urinary tract from the uropathogen E. Coli.
Conclusions. Analyzing the results, it can be concluded that on the model of urinary tract infection against the background of cryogenic exposure, CGPA at a dose of 100 mg/kg showed a uroantiseptic effect, which was stronger than the comparison drug "Inurek" and contributed to a faster disappearance of the titer of colony-forming microorganisms in 1 ml of urine about 2 days earlier than in the group that received dietary supplements of herbal origin "Inurek" and the disappearance of leukocyturia 3 days earlier compared to the group that received therapy with the comparison drug "Inurek". The obtained results indicate the prospects of further research of CGPA with the aim of creating new effective uroantiseptic agents of plant origin based on it
Gut microbiota turn up the heat after bariatric surgery
Authors: Hankir Mohammed K.
Published: September 2023

Bariatric surgeries like vertical sleeve gastrectomy (VSG) and Roux-en-Y gastric bypass (RYGB) cause well-established shifts in the gut microbiota, but how this contributes to their unique metabolic benefits is poorly understood. Jin et al and Yadav et al now provide two complementary lines of evidence suggesting that gut microbiota-derived metabolites after VSG and RYGB activate thermogenesis in fat through distinct mechanisms, to in turn promote weight loss and/or improvements in glycemic control.

Published: September 2023

ABSTRACT Purpose Analyze maternal and child predictors associated with loss to follow-up in the newborn hearing screening program at maternity hospitals in northeastern Brazil. Methods Retrospective cohort study, including secondary data from infants (n=604) referred to the newborn hearing screening program in two maternity hospitals for monitoring and/or diagnosis. The predictors evaluated included socioeconomic factors, such as maternal age, marital status, income, schooling, place of residence, number of children and number of prenatal visits. In addition, maternal and child health factors, such as smoking and drug intake during pregnancy, consanguinity, congenital infections, craniofacial malformations, use of ototoxic drugs, syndromes and a history of hearing loss in the family. Statistical analysis was performed based on binary logistic regression models, using the stepwise method. Results The logistic regression model containing the number of prenatal visits and the history of hearing loss in the family was significant [χ2(2) =34.271; p<0.001]. The number of prenatal visits (OR = 2.343; 95% CI = 1.626 - 3.376) and family history of hearing loss (OR = 2.167; 95% CI = 1.507 - 3.115) were significant predictors. The other predictors were not significant. Conclusion The results reveal that newborns whose mothers had ≤ 5 prenatal visits and those with a family history of hearing loss increased their likelihood of loss to follow-up by 2.3 and 2.1 times, respectively. It is important to provide subsidies for public health improvements in order to help advise, guide and educate mothers, especially during prenatal care.

Resumo A literacia em saúde (LS) é hoje uma importante ferramenta na promoção da saúde e prevenção da doença. O presente estudo, exploratório e correlacional, tem como objetivos: caracterizar os estudantes do ensino superior (ES) relativamente aos seus níveis de LS e de LS digital (e-LS); explorar suas relações com a utilização de redes sociais e comportamentos de saúde; explorar possíveis preditores de LS e e-LS. Participaram no estudo 125 estudantes de diversos cursos, que responderam a instrumentos de autorrelato. Os resultados mostraram níveis de LS em geral acima dos encontrados na população portuguesa, mas abaixo dos níveis de LS nas faixas etárias em que se inserem esses estudantes. Do total de participantes, 42,9% apresentam valores inadequados ou problemáticos, o que constitui uma oportunidade estratégica para a promoção da LS no contexto do ES. O nível de escolaridade da mãe e o próprio sofrer de uma doença crônica revelaram-se preditores significativos da e-LS. As tecnologias digitais podem ser utilizadas como um adequado meio de promoção da saúde dos estudantes do ES, sendo fundamental a identificação de outros preditores de LS e e-LS. As universidades devem incluir a LS nos seus currículos, num conceito alargado de promoção da saúde no ES.
Managing piling obstruction risk intelligently for reinvention of a UK brutalist building

Published: September 2023

Northwood Investors are reinventing a 1980s Brutalist-style London, UK, office building, ‘The Acre’, is located in a densely populated urban environment and surrounded by residential properties. There is a plethora of known and unknown obstructions beneath the site, including heavy steel grillages. Typically, such sites are redeveloped by total demolition and lengthy enabling works with significant vibration and noise. Instead, Northwood decided to replace selectively just 20% of the existing structure while upgrading and re-cladding the remaining 80% to create a modern development, with half the embodied carbon dioxide of the previously consented scheme. To make the scheme viable, Arup proposed the use of Pali Radice piles. This technique can construct mini-piles through layers of obstructions that would defeat traditional piling rigs and can operate in constrained spaces such as existing basements. Despite the choice of piling technique limiting the pile diameter and tender options, this offered a step change in risk control and was crucial to enabling the project. Drilling trials and preliminary pile load testing were undertaken. The trials proved the effectiveness of the technique and informed the pile design. Evidence from the trials permitted the method and programme to be assessed and installation risks to be managed appropriately.
Вплив комбінованих занять з фітнесу на фізичну підготовленість та формування постави у дітей молодшого шкільного віку
Authors: Протас Михайло , Іващенко Ольга , Кравчук Тетяна
Published: September 2023

Мета дослідження – виявити ефективність впливу комбінованих занять з фітнесу для дітей молодшого шкільного віку, побудованих з урахуванням рівня їхньої фізичної підготовленості та особливостей формування постави.
Матеріали і методи.  У дослідженні взяли участь 56 дітей, яким на початок експерименту виконалося 8-9 років, серед них 32 дівчини та 24 хлопця. Було сформовано чотири групи: дві експериментальних ЕГ1 (13) та ЕГ2 (16) та дві контрольні КГ1 (11) та КГ2 (16). Досліджувані експериментальних груп відвідували заняття фітнесом, а діти, що увійшли до контрольних груп займалися фізичними вправами лише під час уроків фізичної культури. У дослідженні були використані наступні методи: вивчення й аналіз літератури; аналіз відеозаписів фітнес програм; педагогічне тестування; візуальний скринінг біогеометричного профілю постави; педагогічний експеримент; методи математичної статистики.
Результати. Вимірювання рівня розвитку фізичних здібностей наприкінці експерименту показало їх значне покращення в групах, де діти додатково до основних занять фізичною культурою в школі відвідували спеціально організовані комбіновані заняття з фітнесу. Найбільш позитивними результатами дослідження стали зміни рівня стану біогеометричного профілю постави досліджуваних ЕГ1. Так, якщо на початку експерименту в ЕГ1 було 2 дитини з низьким та 11 дітей з середнім рівнем, то наприкінці вже 6 дітей мали середній, а 7 покращили свій рівень постави до високого.
Висновки. Експериментально доведено, що для дітей з вадами постави та низьким рівнем фізичної підготовленості фітнес заняття мають наповнюватися переважно низькоударними силовими вправами, які мають коригуючий вплив. До змісту комбінованих занять для дітей з нормальними показниками постави  варто включати високоударні аеробні вправи та будувати заняття за класичною схемою: розминка, аеробна вершина, заминка, силовий блок та стрейтчинг.

EFFECTS OF BEHAVIORAL FINANCE ON SOUTHEAST ASIAN STOCK MARKETS
Authors: Hung Nguyen Hoang , Toan Mai Duc
Published: September 2023

Behavioral finance model is based on the concept of some economic agents prone to psychological error, which explains the financial phenomena known as market anomalies endure. This paper analyzes the variable of trading volume in the Southeast Asian market based on the impact of both rational and irrational agents using linear regression model. The results are notably different from previous works in which the trading volume is both driven by rational and irrational investors, and it fails to reject the rational expectation theory.

The probability density function (PDF) of the hypergeometric is used to model the probability of outcomes of lotto game given some selected predetermined scenarios (K) from (n = 5) samples at the instances of six sample scenarios x = 0, 1, 2, 3, 4, 5. This is exactly mimicking the Nigerian Premier Lotto game where interested players are expected to choose five random numbers from 1 to 90. That ‘A’ win implies that at least three of the randomly chosen 5 numbers are drawn from the national lotto draw often televised to the players. In this paper, different predetermined scenarios are defined and the probability is computed using the probability density function of the hypergeometric distribution. The data are results from 31625 games played on premier lotto in a span of 3 years. The data are for morning, afternoon, night, in Enugu center, regional and national premier lotto results during the period. The chi-square test of goodness of fit shows that the premier lotto is random, fair, and validates the results of the adoption of the PDF of hypergeometric distribution. Players of lotto games are advised to be aware of the slim chances of winning and play reasonably and sensibly.

Cognitive automation powered by advanced intelligent technologies is increasingly enabling
organizations to automate more of their knowledge work tasks. Although this often offers higher
efficiency and lower costs, cognitive automation exacerbates the erosion of human skill and expertise
in automated tasks. Accepting the erosion of obsolete skills is necessary to reap the benefits of
technology—however, the erosion of essential human expertise is problematic if workers remain
accountable for tasks for which they lack sufficient understanding, rendering them incapable of
responding if the automation fails. Though the phenomenon is widely acknowledged, the dynamics
behind such undesired skill erosion are poorly understood. Thus, taking the perspective of
sociotechnical systems, we conducted a case study of an accounting firm that had experienced skill
erosion over a number of years due to reliance on their software’s automated functions. We synthesized
our findings using causal loop modeling based on system dynamics. The resulting dynamic model
explains skill erosion via an interplay between humans’ automation reliance, complacency, and mindful
conduction. It shows how increasing reliance on automation fosters complacency at both individual
and organizational levels, weakening workers’ mindfulness across three work task facets (activity
awareness, competence maintenance, and output assessment), resulting in skill erosion. Such skill
erosion may remain obscure, acknowledged by neither workers nor managers. We conclude by
discussing the implications for theory and practice and identifying directions for future research.
Tragedy, Truth, and Technology: The 3T Theory of Social Media-Driven Misinformation
Authors: Roberts Nicholas ,   Oregon State University, Qahri-Saremi Hamed ,   Colorado State University
Published: September 2023

False claims and misinformation on social media have substantially increased in the last few years. Some people have incorrectly interpreted such content as the truth, sometimes to the extent that it transforms their view of reality and subsequently leads to actions that cause harm and suffering. Despite the burgeoning body of research on misinformation on social media, we know little about the process by which social media-driven misinformation shapes and reinforces false beliefs that result in detrimental outcomes. Building on insights from dramaturgical tragedy, theories of truth, and research on social media, we develop a process theory that explains how social media-driven misinformation transforms a person’s view of reality in a way that leads to detrimental human action.
