Virtual emotional gestures to assist in the examination of the mental health of the deaf-mutes
Authors: Xu Haoming , Liang Hui , Wang Yi , Pan Junjun , Fu Jialin , Pang Xiangwen
Published: April 2023

The particular characteristics of deaf-mutes make them more likely to
have mental health problems. Due to their particular way of
communication, it is more difficult for them to deal with mental health
problems than ordinary people. Nowadays, those psychologists who are
good at sign language are in short supply, and remote assistance cannot
achieve satisfactory results. Therefore, a library of virtual emotional
gestures based on electroencephalogram(EEG) was established and a
prototype system for mental health examination of deaf-mutes was
proposed, which help deaf-mutes identify their psychological problems in
time and assist medical staff to examine the psychological problems
encountered by deaf-mutes. In addition, the virtual library of emotional
gestures is established with the assistance of the chief physician from
a 3A hospital in Henan Province. More importantly, the later experiments
demonstrate the applicability of this virtual system.
Numerical Analysis of Particle Injection Effect on Gas-Liquid Two-Phase Flow in Horizontal Pipelines
Authors: Ranjbari Pouya , Emamzadeh Mohammad , Mohseni Arman
Published: April 2023

In this study, the coupled Eulerian-Lagrangian approach MPPIC-VOF is
adopted, which is capable of capturing solid particle motion as well as
fluid phase development simultaneously. Prior to three-phase flow
simulation, two-phase air-water flow in a specific range of gas and
liquid superficial velocities with slug and plug flow patterns is
simulated. Then, polypropylene particles are injected as the solid phase
into the air-water flow and the effects of particles on pressure drop,
void fraction, and flow patterns are studied. The pressure drop and void
fraction results are validated for both two-phase and three-phase flows
by different correlations and experimental results. As a result of
particle injection at the low concentration of 0.5%, void fraction
increases by 13.7% and pressure drop changes on average by 18%,
respectively. However, there was no significant change in the flow
patterns.
Modeling a chemical plant using gray-box models employing the support vector regression and artificial neural network
Authors: Ghasemi Mahmood
Published: April 2023

In this work, the performances of a nonlinear dynamic industrial process
are examined using gray-box (GB) models. To understand the dynamics of
the system, the transient state is targeted. A white-box (WB) model,
holds the prevailing knowledge using some assumptions. The performance
of this model is limited. Artificial neural network (ANN) and support
vector regression (SVR) which are techniques employed in numerous
chemical engineering applications are employed to construct the
associated black-box (BB) models. GA is used to optimize the SVR
parameters. Dimensional and range extrapolations of different
manipulated inputs, feed concentration, feed temperature, and cooling
temperature of GB model, and BB model are discussed. The different
inputs extrapolation has different results because each input’s
effectiveness in the system is different. The results are compared, and
the best model is suggested among models ANN, SVR, FP-ANN serial
structure, FP-ANN parallel structure, FP-SVR serial structure, and
FP-SVR parallel structure.
A New Variation of Modern Prejudice: South Korean Young Men’s Anti-Feminism and Male-Victim Ideology
Authors: Jung Han
Published: April 2023

In South Korea, anti-feminism is now rapidly spreading through the
Internet among young men, and they started to identify themselves as a
social minority or “victims” of female power. Despite their
ramification to present South Korea, theoretically discussing, they are
actually indistinct from the racism and sexism of White men that emerged
at least a half-century ago. Although they look novel in phenomena, they
share the same root of typical modern racism or sexism. The subtle
sexist undertones hidden in their arguments were discussed by various
psychological theories and empirical data/statistics. Additionally,
various potential factors that may shape or accelerate their attitudes
or behaviors were discussed on the basis of the threat-defense theory
(Jonas et al., 2014). Such factors encompass behavioral/situational
(overindulging violent or degrading Internet contents, verbal
aggression), relational/epistemic (ostracism, attachment insecurity,
pseudo-rationalism), and group levels (provocative interactions,
polarization), some of which may also influence other groups than young
men and ingrain or exacerbate extreme ideologies of other groups,
including young women. Scrutinizing Korean online anti-feminism and
male-victim ideology will help in understanding the psychological
origins of various social extremities or radical ideologies beyond
cultural barriers.
A Sense of Scarcity Enhances the Above-Average Effect in Social Comparison
Authors: Wang Xiaoyan , Jiao Lan
Published: April 2023

Scarcity refers to a state in which an individual’s resources do not
satisfy his/her needs. A sense of scarcity evokes negative emotions. A
fundamental strategy for coping with this negative threat is for people
to emphasize the desirability of their personal traits. In this study,
two behavioral experiments were conducted to examine whether and how a
sense of scarcity affects one’s self-evaluation. Participants were
assigned randomly to the high or low scarcity group. Financial status
(experiment 1) and the amount of assistance rendered to an individual
during a riddle guessing task (experiment 2) were manipulated to induce
a high or low sense of scarcity. Then, the participants were asked to
make trait judgments of themselves compared with their average peers.
The results showed that people with a high sense of scarcity judged
their personality to be more desirable than those with low sense of
scarcity. The results of this study suggest that a sense of scarcity
enhances an individual’s above-average effect in social comparison.
Morpho-tectonics of transpressional systems: insights from analog modeling
Authors: Conrad Ethan Mark , Reitano Riccardo , Faccenna Claudio , Becker Thorsten Wolfgang
Published: April 2023

Transpressional margins are widespread, and their dynamics are relevant
for plate boundary evolution globally. Though transpressional orogen
evolution involves a topographic response to deformation, many studies
focus only on the structural development of the system ignoring surface
processes. Here, we present a new set of analog models constructed to
investigate how tectonic and surface processes interact at transpressive
plate boundaries and shape topography. Experiments are conducted by
deforming a previously benchmarked crustal analog material in a
meter-scale plexiglass box while controlling erosion through misting
nozzles mounted along the transpressional wedge. We used a laser scanner
to generate digital elevation models throughout the model evolution and
photos for particle image velocimetry analysis. We focus on three
experiments that cover a range of rainfall and convergence settings,
with two end-member erosion settings and a dry reference. In all
experiments, a bivergent wedge forms, and strain partitioning broadly
evolves according to previously established models. Regarding drainage
networks, we find that the streams in our models develop differently
through feedback between fault development and drainage rearrangement
processes. Differences between end-member erosional models can be
explained by the varying response of streams to structure modulated by
rainfall. Additionally, erosion may influence the structural evolution
of transpressional topography, leading to accelerated strike-slip
partitioning. From these results, we create a model for developing
structures, streams, and topography where incision and valley formation
along main structures localize exhumation. We apply insights from the
models to natural transpressional systems, including the Transverse
Ranges, CA., and the Venezuelan Andes.
Stochastic dynamics of two-dimensional particle motion in Darcy-scale heterogeneous porous media
Authors: Dell'Oca Aronne , Dentz Marco
Published: April 2023

We study the upscaling and prediction of dispersion in two-dimensionalheterogeneous porous media with focus on transverse dispersion. To this
end, westudy the stochastic dynamics of the motion of advective particles that
movealong the streamlines of the heterogeneous flow field. While
longitudinaldispersion may evolve super-linearly with time, transverse dispersion
ischaracterized by ultraslow diffusion, that is, the transverse
displacement variance grows asymptotically with the logarithm of time.
This remarkable behavior is linked to the solenoidalcharacter of the flow field, which needs to be accounted for in
stochasticmodels for the two-dimensional particle motion. We analyze particle
velocitiesand orientations through equidistant sampling along the particle
trajectoriesobtained from direct numerical simulations. This sampling strategy
respects the flow structure, which is organized on a characteristic
length scale. Perturbation theory shows that the longitudinal particle
motion is determined by the variability of travel times, while the
transverse motion is governed by the fluctuations of the space
increments. The latter turns out to be strongly anti-correlated with a
correlation structure that leads to ultraslow diffusion. Based on this
analysis, we derive astochastic model that combines a correlated Gaussian noise for the
transversemotion with a spatial Markov model for the particle speeds. The model
resultsare contrasted with detailed numerical simulations in two-dimensionalheterogeneous porous media of different heterogeneity variance.
Using Frequent, High-Resolution Remote Sensing to Identify Intermittent and Overlapping CH4 sources in Oil and Gas Development Regions

Published: April 2023

The oil and natural gas industry needs accurate and frequent information
on methane CH4 emissions from all of their facilities globally in order
to effectively reduce emissions. Here we describe the development of
requirements for a constellation of satellites to provide frequent data
on point source CH4 emissions from the oil and gas industry. Three types
of sources were examined: isolated continuous plumes with emissions
rates of 50 kg hr-1, intermittent CH4 releases from activities such as
compressor start-ups, and overlapping continuous plumes. The dispersion
model SCICHEM was used to simulate the dispersion of methane plumes and
intermittent releases for typical meteorology in the Permian Basin, and
a plume mask and integrated mass enhancement (IME) algorithm were
applied to identify and quantify the emissions. The precision and ground
sampling distance of the future satellite instrument were varied to
determine the required precision and horizontal resolution of the
satellite instrument. We find that quantifying CH4 point source
emissions as small as 50 kg hr-1 by remote sensing requires a ground
sampling distance of 30-60 m and a CH4 column precision of 0.5-1.0% for
the range of conditions analyzed. Detecting intermittent sources is also
possible with the above instrument specifications if the puff is
observed within 15 min of emission. Plumes of similar source strengths
more than 0.5 km apart can be separated with existing plume
identification approaches but separating sources closer than that or
with very different emission rates will require further development of
plume identification techniques.
The impact of the Madden-Julian Oscillation on the formation of the Arabian Sea Monsoon Onset Vortex
Authors: Dhavale Shreyas , Aiyyer Anantha
Published: April 2023

During some years, a synoptic scale vortex called the Monsoon Onset
Vortex (MOV) forms within the northward advancing zone of precipitating
convection over the Arabian Sea. The MOV does not form each year and the
reason is unclear. Since the Madden-Julian Oscillation (MJO) is known to
modulate convection and tropical cyclones in the tropics, we examined
its role in the formation of the MOV. While the convective and
transition phases of the MJO do not always lead to MOV formation, the
suppressed phase of the MJO hinders the formation of the MOV more
consistently. This non-linear relationship between the MJO and MOV can
be partially explained by the modulation of the large-scale environment,
measured by a tropical cyclone genesis index. It also suggests that the
Arabian Sea is generally near a critical state that is favorable for MOV
formation during the monsoon onset period.
Using financial contracts to facilitate informal leases within a Western United States water market based on prior appropriation
Authors: Zeff Harrison B , Hadjimichael Antonia , Reed Patrick M. , Characklis Gregory W.
Published: April 2023

The ability to reallocate water to higher-value uses during drought is
an increasingly important ‘soft-path’ tool for managing water resources
in an uncertain future. In most of the Western United States,
state-level water market institutions that enable reallocation also
impose substantial transaction costs on market participants related to
regulatory approval and litigation. These transaction costs can be
prohibitive for many participants in terms of both costs and lengthy
approval periods, limiting transfers and reducing allocation efficiency,
particularly during drought crises periods. This manuscript describes a
mechanism to reduce transaction costs by adapting an existing form of
informal leases to facilitate quicker and less expensive transfers among
market participants. Instead of navigating the formal approval process
to lease a water right, informal leases are financial contracts for
conservation that enable more junior holders of existing rights to
divert water during drought, thereby allowing the formal transfer
approval process to be bypassed. The informal leasing approach is tested
in the Upper Colorado River Basin (UCRB), where drought and
institutional barriers to transfers lead to frequent shortages for urban
rights holders along Colorado’s Front Range. Informal leases are
facilitated via option contracts that include adaptive triggers and that
define volumes of additional, compensatory, releases designed to
mitigate impacts to instream flows and third parties. Results suggest
that more rapid reallocation of water via informal leases could have
resulted in up to $222 million in additional benefits for urban rights
holders during the historical period 1950 – 2013.
Old dog, new trick: Reservoir computing advances machine learning for climate modeling
Authors: Bretherton Christopher S.
Published: April 2023

Physics-informed machine learning (ML) applied to geophysical simulation
is developing explosively. Recently, graph neural net and vision
transformer architectures have shown 1-7 day global weather forecast
skill superior to any conventional model with integration times over
1000 times faster, but longer simulations rapidly degrade. ML that
achieves high skill in both weather and climate applications is a
tougher goal. This Commentary was inspired by
\citeA{ArcomanoEtAl2023}, who show impressive progress
toward that goal using hybrid ML, combining reservoir computing to a
coarse-grid climate model and coupling to a separate data-driven
reservoir computing model that interactively predicts sea-surface
temperature. This opens new horizons; where will the next ML
breakthrough come from, and is conventional climate modeling about to be
disrupted?
Short term prediction of geomagnetic secular variation with an echo state network
Authors: Nakano Shin'ya , Toh Hiroaki
Published: April 2023

A technique for predicting the secular variation (SV) of the geomagnetic
field based on the echo state network (ESN) model is proposed. SV is
controlled by the geodynamo process in the Earth’s outer core. However,
it is difficult to model the realistic nonlinear behaviors of the
geodynamo due mainly to the very small Ekman number of the actual outer
core. This study employs the ESN to represent the temporal evolution of
the geomagnetic field on the Earth’s surface. The hindcast results of SV
demonstrate that the ESN enables us to predict SV for several years with
satisfactory accuracy. In particular, the nonlinear behaviors of SV is
accurately predicted for the case where accurate geomagnetic data with a
1-year time resolution are available. It is found that an increase in
the number of training data does not necessarily improve prediction
accuracy. The results suggest that the information on the latest
temporal variations is important for the short-term prediciton by the
ESN valid for, say 5 years.
Parameterized internal wave mixing in three ocean general circulation models
Authors: Brueggemann Nils , Losch Martin , Scholz Patrick , Pollmann Friederike , Danilov Sergey , Gutjahr Oliver , Jungclaus Johann H , Koldunov Nikolay V. , Korn Peter , Olbers Dirk , Eden Carsten
Published: April 2023

The parameterization IDEMIX for vertical mixing by breaking internal
gravity waves is evaluated in three different non-eddy resolving ocean
models. Three different products of wave forcing by tidal flow over
topography, representing the current uncertainty, are applied and
compared to reference simulations without IDEMIX, allowing the
model-independent effects of the new closure to be assessed. Common to
all models is larger interior mixing work with stronger horizontal
structure due to the inhomogeneous forcing functions in all simulations
using IDEMIX, in better agreement to observations. Coherent model
responses to the stronger mixing work are changes in the thermocline
depth including IDEMIX related to stronger shallow overturning cells in
the Indo-Pacific Ocean. Furthermore, deeper mixed layer depths in the
subpolar North Atlantic are related to an increase of the Atlantic
overturning circulation which brings the model closer to observations,
coming along with an increase in northward heat transport. In the
Southern Ocean, excessive energy input by one of the forcing products
leads to unrealistic deep convection in the Weddell Sea in one of the
models. The deep Indo-Pacific overturning circulation and the bottom
cell of the Atlantic feature an incoherent model response, which may
point towards the importance of excessive numerical mixing in the
models.
TROPOMI-derived NO2 emissions from copper/cobalt mining and other industrial activities in the Copperbelt (DRC and Zambia)

Published: April 2023

We have analyzed TROPOMI data over the Copperbelt mining region
(Democratic Republic of Congo and Zambia). Despite high background
values, we find that annual 2019-2022 means of TROPOMI NO2 show local
enhancements consistent with six point sources (mines and cities) where
high-emission industrial activities take place. We have quantified
annual NO2 emissions for the six sources, identified temporal trends in
these emissions, and found strong correlations with mine/refinery
production data. CAMS-GLOB-ANT v5 inventory emissions are lower than
TROPOMI-derived emissions by 61-96 % and lack the temporal trends
observed in TROPOMI and mine/oil refinery production. Lack of TROPOMI
SO2 enhancements over the point sources analyzed indicates SO2 capture
and transformation into sulfuric acid, a profitable byproduct. These
results demonstrate the potential for satellite monitoring of mining/oil
refining activity which impacts the air quality of local communities.
This is particularly important for Africa, where mining is increasing
aggressively.
Numerical diffusion and turbulent mixing in convective self-aggregation
Authors: Silvestri Lorenzo , Saraceni Miriam , Cerlini Paolina Bongioannini
Published: April 2023

Spontaneous aggregation of deep convection is a common feature of
idealized numerical simulations of the tropical atmosphere in
Radiative-Convective Equilibrium (RCE). However, at coarse grid
resolution where deep convection is not fully resolved, the occurrence
of this phenomenon is extremely sensitive to subgrid-scale processes.
This study focuses on the role played by mixing and entrainment, either
provided by the turbulence model or the implicit numerical dissipation.
We have analyzed the results of two different models, WRF and SAM, and
we have compared different configurations by varying the turbulence
models, the numerical schemes and the horizontal spatial resolution. At
coarse grid resolution (3 km), removing turbulent mixing prevents the
occurrence of Convective Self-Aggregation (CSA) in low numerical
diffusion models, while delaying it in high numerical diffusion models.
When the horizontal grid resolution is refined to 1 km (thus reducing
the implicit numerical dissipation), CSA is achieved only by increasing
the explicit turbulent mixing. In this case, CSA was found to occur even
with a small amount of shallow clouds. Therefore, this study suggests
that the sensitivity of CSA to horizontal grid resolution is not
primarily due to the corresponding decrease in shallow clouds. Instead,
it is found that turbulent mixing and dissipation at small scales
regulate the amplitude of humidity perturbations introduced by
convection in the free troposphere: the greater the dissipation at small
scales, the greater the size and the strength of humidity perturbations
in the free troposphere that can destabilize the RCE state.
Constraints on Southern Ocean Shortwave Cloud Feedback from the Hydrological Cycle
Authors: Tan Chuyan , McCoy Daniel Thompson , Elsaesser Gregory
Published: April 2023

Shifts in Southern Ocean (SO, 40-85S) shortwave (SW) cloud feedback
(SWFB) towards more positive values are the dominant contributor to
higher effective climate sensitivity (ECS) in Coupled Model
Intercomparison Project phase 6 (CMIP6) models. The positive shift in
SWFB in CMIP6 global climate model (GCMs) can be traced back to the
greater reduction in low cloud cover and the weaker cloud liquid water
response to warming in the SO. To evaluate how realistic the CMIP6 cloud
response is, we connect the SO SWFB to changes in column-integrated
liquid water mass (LWP) and the susceptibility of albedo to LWP in 50
CMIP5 and CMIP6 GCMs. In turn, we predict the responses of SO LWP to
warming using a cloud-controlling factor (CCF) model. The combination of
the CCF model and radiative susceptibility explains about 50% of the
variance in the GCM-simulated SWFB in the SO. Observations of SW
radiation fluxes, LWP, and reanalysis of CCFs are used to constrain the
SO SWFB. This yields a constrained response of SO LWP to warming of
2.89-4.41 gm-2K-1, relative to the total GCM range of -0.48-9.33
gm-2K-1. The susceptibility of albedo to LWP is constrained to be
0.41-0.86 (kgm-2)-1, relative to the GCM range of 0.23-3.62 (kgm-2)-1,
where albedo is unitless. The overall constraint on the contribution of
SO SWFB to global cloud feedback is -0.19-0.05 Wm-2K-1, relative to GCM
range of -0.28-0.27 Wm-2K-1. In summary, observations suggest a moderate
negative to weak positive SO SWFB.
Centennial-scale intensification of wet and dry extremes in North America
Authors: Sung Kyungmin , Bohrer Gil , Stagge James Howard
Published: April 2023

Drought and pluvial extremes are defined as deviations from typical
climatology; however, the background climatology can shift over time in
a non-stationary climate, impacting interpretations of extremes. This
study evaluated changes in meteorological drought and pluvial extremes
by merging tree-ring reconstructions, observations, and climate-model
simulations spanning 850 – 2100 CE across North America to determine
whether the Industrial era and projected future lie outside the range of
natural climate variability. Our results found widespread and spatially
consistent exacerbation of both extremes, especially summer drought and
winter pluvials, with west and south drying, the northeast wetting
trends, and increased interannual variability across the east and north.
Our study underscores climate change has already shifted precipitation
climatology beyond pre-Industrial climatology and is projected to
further intensify ongoing shifts.
Health Informatics Internship: What Are the Students Perceptions Regard Internship Effectiveness?
Authors: Alhur Anas Ali
Published: April 2023

Internship programs allow students to gain practical experience while learning from professionals. Unfortunately, several barriers are associated with internships, including a lack of defined objectives, no guidance or mentorship, poorly defined tasks, strict deadlines, no opportunities for growth or the acquisition of new skills, no networking opportunities, exclusion from meetings, and insufficient training. Thus, this study aimed to evaluate the state of health informatics (HI) internship programs at the University level. The researcher conducted a cross-sectional approach. This study collected data using a questionnaire. The Statistical Package for Social Sciences (SPSS) 26.0 (Version 26) was used in data analysis.The students indicated that internships positively influenced their learning, interpersonal and personal skills, and employment prospects. However, they also encountered some challenges when they intended to meet with the internship coordinator. Some bias may be present in the reporting. Respondents may have inadvertently misinterpreted the questions, inaccurately expressed their opinions, or simply misunderstood them. Finally, the lack of open-ended questions prevented respondents from expressing their opinions comprehensively. The researcher recommended that soft skills should be emphasized in the curriculum for HI and health information management (HIM). The site supervisor must understand the HI field and the interns' responsibilities, allowing them to apply some of what they have learned.

Disability inclusion is adopted as the main strategy to address poverty among persons with disabilities. In low- and middle-income countries like Indonesia, the development disability gap is prevailing. Hence, this study aimed to analyze the most recent disability-inclusive efforts in development programs in Indonesia and to identify priorities for scaling up. This study use literature review and descriptive in nature. It employed the linear six-phased procedures of the thematic analysis approach in analyzing data. A total of 12 articles were selected through the semi-systematic method. Based on the findings, there are efforts in providing social and economic disability-inclusive opportunities, and emerging minimal opportunities for PWDs in the political arena. Social and legal protection is progressing but remains lacking in other provisions and several development endeavors had implemented strategic interventions, however, challenges persist. Several recommendations were identified which could serve as priorities for the future development agenda for local and national policymakers, implementers, and stakeholders. However, this study suggests further investigation into how the proposed recommendations from previous studies are being implemented by the public and private development sectors. Also, examining culturally appropriate and sensitive tools is necessary for translating the challenges into action to ensure the scalability, replicability, and sustainability of the country’s disability-inclusive development efforts.

The Effectiveness of RME Approach to Elementary School Students' Mathematical Abilities: A Meta-Analysis Study
Authors: Samritin
Published: April 2023

Various studies examining the effectiveness of the RME approach to the mathematics abilities of elementary school students have yielded inconsistent results. Therefore, this study aims to analyze the effectiveness of the RME approach to the mathematics abilities of elementary school students by using a type of meta-analysis research approach. This meta-analytic study analyzed 10 primary studies published in the last ten years. Data collection uses Google Scholar, ERIC, DOAJ, Springer, AIP Proceedings, IOP Sciences, and Elsevier databases. The results of the analysis show that the application of the RME approach has an effect on the mathematics abilities of elementary school students when compared to traditional learning (g = 0.63; p <0.01). The results of the moderator variable analysis showed that the effect of applying the RME approach to the mathematics abilities of elementary school students differed significantly based on class level (Qb = 6.01; p = 0.01) and sample size (Qb = 7.63; p = 0.01). However, there was no significant difference by year of study group (Qb = 3.16; p = 0.08) and type of publication (Qb = 2.58; p = 0.11). These findings are expected to be the basis for selecting strategies for learning mathematics in elementary schools so that the quality of learning can be improved.

Published: April 2023

Education is currently inseparable from technological developments. The integration of technology into the education field provides renewal in various aspects. One of them is the use of technology in the learning process. The problems found in the Indonesian History subject were the low interest and low learning outcomes of the students. This is due to the great influence of smartphone development. One way to increase the students' understanding and interest in learning history is through an electronic form of LKPD (E-LKPD) displayed via the web. This research aims to analyze the process, validity, practicality and effectiveness of the web-based E-LKPD development for Indonesian History subject for Grade XI Senior High School. This study used the development and research (R&D) method with the ADDIE model.

Respiration is one of the difficult biology topics, and teachers have challenges effectively teaching it to minimise misconceptions. The aims of this study was to analyse the effect of guided inquiry computer simulations on pre-service teachers' performance. A quasi-experimental design was used in this study. The subject in this study involving 65 in-service teachers, consist of 33 experimental groups taught using guided inquiry computer simulations, and 32 control groups received instructions using traditional chalk-and-talk. Data were collected using the Academic Performance Test and analysed using a T-test to determine the differences between the groups. Analysis of Covariance was used to find out the effect of the intervention. Both groups were pre-tested to gauge their previous knowledge and post-tested to establish changes after the teaching. The results show experimental group surpassed the control group. Also, males and females performance in the experimental group was similar, suggesting that guided inquiry computer simulations favoured both genders. It implies that guided inquiry computer simulations are effective tools to minimise misconceptions regarding cellular respiration. Thus, the researchers recommend using guided inquiry computer simulations in qualitative and quantitative approaches with a large sample of in-service teachers from different geographic regions.
