Characterization of Magnetic Flux Contents for Flux Transfer Events and its Implications for Flux Rope Formation at the Earth's Magnetopause
Authors: Wang Shuo , Zou Ying , Hu Qiang , Shi Xueling , Hasegawa Hiroshi
Published: October 2023

Flux transfer events (FTEs) are a type of magnetospheric phenomena that
exhibit distinctive observational signatures from the in-situ spacecraft
measurements across the Earth’s magnetopause. They are generally
believed to possess a magnetic field configuration of a magnetic flux
rope and formed through magnetic reconnection at the dayside
magnetopause, sometimes accompanied with enhanced plasma convection in
the ionosphere. We examine two FTE events under the condition of
southward interplanetary magnetic field (IMF) with a dawn-dusk component
at the magnetopause by applying the Grad-Shafranov (GS) reconstruction
method to the in-situ measurements by the Magnetospheric Multiscale
(MMS) spacecraft to derive the magnetic flux contents associated with
the FTE flux ropes. In particular, given a cylindrical magnetic flux
rope configuration derived from the GS reconstruction, the magnetic flux
content can be characterized by both the toroidal (axial) and poloidal
fluxes. We then estimate the amount of magnetic flux (i.e., the
reconnection flux) encompassed by the area “opened” in the ionosphere,
based on the ground-based Super Dual Auroral Radar Network (SuperDARN)
observations. We find that for event 1, the FTE flux rope is oriented in
the approximate dawn-dusk direction, and the amount of its poloidal
magnetic flux agrees with the corresponding reconnection flux. For event
2, the agreement among the estimates of the magnetic fluxes is
uncertain. We provide a detailed description about our interpretation
for the topological features of the FTE flux ropes, based on a formation
scenario of sequential magnetic field reconnection between adjacent
field lines, consistent with our results.
A new mechanism for mineralizing systems based on cnoidal wave instabilities
Authors: Liu Chong , Calo Victor , Tannock Lisa , Lieb Klaus Regenauer- , Hu Manman
Published: October 2023

The formation of mineral deposits in mesothermal quartz veins is a
complex process that has been the subject of much research. The
classical fault-valve hypothesis suggests that mineralization occurs
when metamorphic fluids are injected during a brittle event and then
locked in to mineralize, but this hypothesis does not fully explain the
regular spacing of repeated mineralized patterns that are often
observed. This paper proposes a new mechanism for mineralizing systems
based on the theory of cnoidal waves in solids. Cnoidal waves are
standing waves that can persist for long times in materials under
compressive and extensional regimes. We investigate mineral deposits by
analytical and numerical methods and show that the cnoidal wave
instability theory provides a plausible alternative mechanism for
mineralizing systems. This study opens a new avenue for field studies to
demonstrate that the mechanism-based cnoidal waves play an essential
role in the formation of mineral deposits.
Experimental study on flow characteristics of compound-braided river channel
Authors: ZHANG Jing , Tong Qin , Wang Dong , Xiang Bo , GUO Zhixue , Gan Xiaoyan , Wen Xia
Published: October 2023

Braided rivers easily form wide and shallow floodplains when there is no
constraints on both sides of the river. During floods, rising water
level submerges the floodplain of the bifurcated channel, resulting in
the Compound-Braided River. The generalized model was established based
on statistical data from the braided river reach of Heilongjiang. In
this paper, the flow field of the straight compound-braided river was
measured in flume experiments, and then the effect of the interaction of
floodplain and main channel on the flow pattern, water level, flow
structure and resistance force were studied under overbank flow
conditions. The split ratio variation trend is further discussed. The
results show that hydraulic factors in diverge segment were mainly
related to braided reach, with high longitudinal velocity observed in
inner floodplain. The exchange flow between floodplain and main channel
accelerates transverse flow and promotes sediment transport intensity
laterally. Secondary flow of compound section within the influence range
of bifurcated flow was obviously inhibited. Boundary shear stress
analysis showed that the diversion ratio of the main tributary under
overbank condition decreased slightly and would maintain constant values
as surface rise.
Implications of localized time dilation
Authors: Seagraves David A.
Published: October 2023

Abstract: The assumption that time dilation must be computed using
velocities relative to the local Hubble Frame has important consequences
for cosmology. Four such consequences are described: (1) the impact on
redshift calculations, (2) an alternate explanation of the apparent
accelerated rate of expansion of the universe, (3) a reinterpretation of
the period of inflation following the Big Bang, and (4) reevaluation of
the computation of time dilation experienced during space travel, such
as that postulated in the Twins Paradox.
Surface Rupture and Fault Characteristics Associated with the 2020 Magnitude (MW) 6.6 Masbate Earthquake, Masbate Island, Philippines
Authors: Llamas Deo Carlo E. , Marfito Bryan J. , Cruz Ronald Dela , Aurelio Mario
Published: October 2023

The magnitude (M) 6.6 earthquake that
struck Masbate Island on 18 August 2020 offers a unique opportunity to
investigate the slip and seismic behavior of the Philippine Fault in the
Masbate region. In this study, we employ InSAR, seismicity analysis, and
field investigations to comprehensively characterize the coseismic and
postseismic slip associated with the event. Our findings reveal a
50-km-long fault rupture along the Masbate segment of the Philippine
Fault, with ~23 km surface rupture mapped onshore,
despite the occurrence of interseismic creep. The slip distribution
demonstrates decreasing displacements northwestward towards the creeping
section, with a maximum left-lateral displacement of 0.97 m near the
epicenter. Toward the southeast offshore, the rupture terminates at
a fault left stepover. While the surface rupture appears relatively
straight and narrowly concentrated, the secondary ruptures and mapped
offshore faults reveal a more complex transtensional fault structure in
the vicinity of Cataingan Bay. This fault complexity represents an
asperity that facilitates high-stress accumulation and rupture
initiation. Postseismic slip persists for several months along the
onshore creeping segment. We derived a slip rate of 2.8 to 4.3 cm/year
from long-term and short-term slip measurements. Furthermore, we
calculated a recurrence interval of 16 to 41 years for earthquakes
similar to the 2020 Masbate earthquake.  Our study highlights how
heterogeneity in fault properties, including geometry and coupling
state, influences the distribution of slip and magnitude of earthquakes.
The 2020 Masbate earthquake provides valuable insights into the rupture
dynamics and fault behavior of the Philippine Fault in the Masbate
region.
The 2022 Starlink geomagnetic storms: global thermospheric response to a high-latitude ionospheric driver
Authors: Billett Daniel D , Sartipzadeh Kian , Ivarsen Magnus Fagernes , Iorfida Elisabetta , Doornbos Eelco , Eyigüler Emine Ceren Kalafatoglu , Pandey Kuldeep , McWilliams Kathryn A
Published: October 2023

In this study, we present ionospheric observations of field-aligned
currents from AMPERE and the ESA Swarm A satellite, in conjunction with
high-resolution thermospheric density measurements from accelerometers
on board Swarm C and GRACE-FO, for the 3rd and 4th February 2022
geomagnetic storms that led to the loss of 38 Starlink internet
satellites. We study the global storm time response of the thermospheric
density enhancements, including their growth, decay, and latitudinal
distribution. We find that the thermospheric density enhances globally
in response to high-latitude energy input from the magnetosphere-solar
wind system, and takes at least a full day to recover to pre-storm
density levels. We also find that the greatest density perturbations
occur at polar latitudes consistent with the magnetosphere-ionosphere
dayside cusp, and that there appeared to be a saturation of the
thermospheric density during the geomagnetic storm on the 4th. Our
results highlight the critical importance of high-latitude ionospheric
observations when diagnosing potentially hazardous conditions for
low-Earth-orbit satellites.
Bidispersity unlikely as a factor for the long runout of large mass flows: scale bias in analogue granular flow experiments
Authors: Makris Symeon , Manzella Irene , Sgarabotto Alessandro
Published: October 2023

The bidispersity observed in the grain-size distribution of rock
avalanches and volcanic debris avalanches (rock/debris avalanches) has
been proposed as a property contributing to their long runout. This has
been supported by small-scale analogue experimental studies which
propose that a small proportions of fine particles, mixed with coarser,
enhances granular avalanche runout. However, the mechanisms enabling
this phenomenon and their resemblance to rock/debris avalanches have not
been directly evaluated. Here, binary mixture granular avalanche
experiments are employed to evaluate the potential of bidispersity in
enhancing runout. Structure-from-motion photogrammetry is used to assess
centre of mass mobility. The findings suggest that the processes
generating increased runout in small-scale avalanches are
scale-dependent and not representative of rock/debris avalanche
dynamics. In small-scale experiments, the granular mass is
size-segregated with fine particles migrating to the base through
kinetic sieving. At the base, they reduce frictional areas between
coarse particles and the substrate, and encourage rolling. The reduced
frictional energy dissipation increases kinetic energy conversion, and
avalanche mobility. However, kinetic sieving does not occur in
rock/debris avalanches due to a dissimilar granular flow regime. The
proposition of this hypothesis overlooks that scale-dependent behaviours
of natural events are omitted in small-scale experiments. At the small
scale, a collisional regime enables the necessary agitation for kinetic
sieving. However, rock/debris avalanches are unlikely to acquire a
purely collisional regime, and rather propagate under a frictional
regime, lacking widespread agitation. Therefore, bidispersity is
unlikely to enhance the mobility of rock/debris avalanches by enabling
more efficient shearing at their base.
High-latitude eddy covariance temporal network design and optimization.

Published: October 2023

Ecosystems at high latitudes are under increasing stress from climate
change. To understand changes in carbon fluxes, in situ measurements
from eddy covariance networks are needed. However, there are large
spatiotemporal gaps in the high-latitude eddy covariance network. Here
we used the relative extrapolation error index in machine learning-based
upscaled gross primary production as a measure of network
representativeness and as the basis for a network optimization. We show
that the relative extrapolation error index has steadily decreased from
2001 to 2020, suggesting diminishing upscaling errors. In experiments
where we limit site activity by either setting a maximum duration or by
ending measurements at a fixed time those errors increase significantly,
in some cases setting the network status back more than a decade. Our
experiments also show that with equal site activity across different
theoretical network setups, a more spread out design with shorter-term
measurements functions better in terms of larger-scale
representativeness than a network with fewer long-term towers. We
developed a method to select optimized site additions for a network
extension, which blends an objective modeling approach with expert
knowledge. Using a case study in the Canadian Arctic we show several
optimization scenarios and compare these to a random site selection
among reasonable choices. This method greatly outperforms an unguided
network extension and can compensate for suboptimal human choices.
Overall, it is important to keep sites active and where possible make
the extra investment to survey new strategic locations.
Model biases in the atmosphere-ocean partitioning of poleward heat transport are persistent across three CMIP generations
Authors: Donohoe Aaron , Fajber Robert , Cox Tyler , Armour Kyle , DBattisti David , Roe Gerard
Published: October 2023

The observed partitioning of poleward heat transport between atmospheric
and oceanic heat transports (AHT and OHT) is compared to that in coupled
climate models. Poleward OHT in the models is biased low in both
hemispheres, with the largest biases in the Southern Hemisphere
extratropics. Poleward AHT is biased high in the Northern Hemisphere,
especially in the vicinity of the peak AHT near
40$^\circ$N. The significant model biases are
persistent across three model generations (CMIP3, CMIP5, CMIP6) and are
insensitive to the satellite radiation and atmospheric reanalyses
products used to derive observational estimates of AHT and OHT. Model
biases in heat transport partitioning are consistent with biases in the
spatial structure of energy input to the ocean and atmosphere.
Specifically, larger than observed model evaporation in the tropics adds
excess energy to the atmosphere that drives enhanced poleward AHT at the
expense of weaker OHT
Towards Flash Flood Modeling Using Gradient Resolving Representative Hillslopes
Authors: J Ashish Manoj , Loritz Ralf , Villinger Franziska , Mälicke Mirko , Koopaeidar Mehdi , Göppert Hans , Zehe Erwin
Published: October 2023

It is increasingly acknowledged that the acceleration of the global
water cycle, largely driven by anthropogenic climate change, has a
disproportionate impact on sub-daily and small-scale hydrological
extreme events such as flash floods. These events occur thereby at local
scales within minutes to hours, typically in response to high-intensity
rainfall events associated with convective storms. Despite their local
scale and rapid onset, the effects of flash floods can be devastating,
making their prediction and mitigation of critical importance. However,
the modeling and analysis of such events in data-scarce regions present
a unique set of challenges. In the present work, we show that by
employing physically based representative hillslope models that resolve
the main gradients controlling overland flow hydrology and hydraulics,
we can get reliable simulations of flash flood response in small
data-scarce catchments. To this end, we use climate reanalysis products
and transfer soil parameters previously obtained for hydrological
predictions in an experimental catchment in the same landscape. The
inverted mass balance of flood reservoirs downstream is employed to
derive a target data set for model evaluation in these nearly ungauged
basins. We show that our approach using representative hillslopes and
climate datasets can provide reasonable uncalibrated estimates of the
overland runoff response in three of the four catchments considered.
Given that flash floods typically occur at scales of a few km2 and in
ungauged places, our results have implications for operational flash
flood forecasting and the design of small and medium flood retention
basins around the world.
No major increase in erosion rates in Central Himalayas during the late Cenozoic, revealed by 10Be in the newly dated Valmiki Siwalik section.

Published: October 2023

The Glaciations impacted erosion during the Late Cenozoic but no
consensus has emerged whether they led to increased erosion rates
globally. In the Himalayas, recent work used past sediment
concentrations of the terrestrial cosmogenic nuclide (TCN) 10Be and
demonstrated that erosion rates have not permanently increased in the
Himalayas. However, for the Quaternary, the published sedimentary
records suffer from provenance uncertainties which prevent to elaborate
on the causes of steady erosion rates. Here, we document the new,
4,000-m thick Valmiki Section (VS) to address this question. In the
remote Valmiki Tiger Reserve, the VS consists of Siwalik sediment
deposited in the Himalayan foreland basin by the Narayani River, a major
river of Central Himalayas. To quantify past Himalayan erosion rates
from TCN 10Be measurements, we determine: (1) the magnetostratigraphic
deposition age model, (2) provenance using major elements and Sr-Nd
isotopes, and (3) the recent cosmic exposure related to Siwalik
exhumation using TCN 36Cl measurement in feldspar. The VS records
Himalayan erosion from 7.5 to 1.25 Ma. Our 10Be results confirm steady
erosion rates, close to modern values, 1.4-2.3 mm/y, with a brief
increase by 35% at 2 Ma, possibly due to sustained glacial erosion of
the high peaks as suggested by the geochemical signature. The Narayani
Catchment may be more sensitive to the onset of the Glaciations because
of larger glacial cover (presently ~10%) than elsewhere
in the Himalayas. Despite this sensitivity, our results support that
over long timescales, rather than climate, tectonics control Himalayan
erosion.
Backprojection Imaging Based on a 3D Model: Method and Applications on the 2017 Mww8.1 Mexico Earthquake and Mw7.7 Russia Earthquake
Authors: Song Chao , Ge Zengxi
Published: October 2023

In this study, we carried out a backprojection (BP) analysis to image
the rupture process of the newly happened September 8, 2017 Mww8.1
Mexico earthquake based on a global 3D P-wave tomography model, the
LLNL-G3Dv3 model. Limited to epicenter distance and data quality, only
waveform observation data from Alaska (AL), USA was utilized finally,
with some data from South America (SA) as supplement. First, we compared
the HF BP results of 1D and 3D model to illustrate the higher resolution
and reliability of the 3D one. Then we discussed the consistency among
the overall rupture pattern, the main event focal mechanism and
aftershocks distribution, and further inferred the possible fault
geometry. After that, we explained the rationality of the setting for
rupture duration based on beamforming energy pattern, normalized power
variation and other previous works. We then seriously examined the
creditability of stage 2 and explained why speed in stage 2 is much
bigger than in 1. Finally, we obtained the coulomb stress change
imparted on the faults of the subsequent September 19 Mww7.1 event and
September 23 Mww6.1 event to find out if they are positively triggered
by this main event. From our current research, the complete
~53s rupture process of this earthquake can be divided
into two stages. In stage 1, which lasted for ~37s, the
rupture propagated from the epicenter towards the NW direction
(~330°measured from north clockwise) with a speed of
~2.8 km/s, and extended to a length of
~89 km. Then it made a right turn and shortly after, it
continued to propagate to near N (~3°) with a higher
speed of ~5.3 km/s and a scale of ~75
km. Our study intended to believe that the Mww8.1 event has almost
nothing to do with the Mww7.1 event while it strongly triggered the
occurrence of the latter Mww6.1 event.
An Assessment of Antarctic Sea-ice Thickness in CMIP6 Simulations with Comparison to the Observations
Authors: Trivedi Shreya , Hobbs William R. , Raphael Marilyn
Published: October 2023

This study assesses less-explored Southern Ocean sea-ice parameters,
namely Sea-ice Thickness and Volume, through a comprehensive comparison
of 26 CMIP6 models with reanalyses and satellite observations. Findings
indicate that models replicate the mean seasonal cycle and spatial
patterns of sea-ice thickness, particularly during its maxima in
February. However, some models simulate implausible historical mean
states compared to satellite observations, leading to large inter-model
spread. September sea-ice thickness is consistently biased low across
the models. Our results show a positive relationship between modeled
mean sea-ice area and thickness in September (i.e., models with more
area tend to have thicker ice); in February this relationship becomes
negative. While CMIP6 models demonstrate proficiency in simulating Area,
thickness accuracy remains a challenge. This study, therefore,
highlights the need for improved representation of Antarctic sea-ice
processes in models for accurate projections of thickness and volume
changes.
Developing a physics-informed variational autoencoder (VAE) approach to construct a reduced-order model of the lee vortex in Taiwan
Authors: Hsieh Min-Ken , Wu Chien-Ming
Published: October 2023

This study develops a physics-informed neural network (PINN) model to
efficiently generate high-fidelity local circulation patterns in Taiwan
while preserving an accurate representation of the physical relationship
between generated local turbulence and upstream synoptic flow regimes.
Large ensemble semi-realistic simulations were conducted using a
high-resolution (2 km) TaiwanVVM model, in which the critical
characteristics of the various synoptic flow regimes are carefully
selected to concentrate on the effects of local circulation variations.
A variational autoencoder (VAE) was constructed to capture essential
representations of local circulation scenarios associated with the lee
vortices by training on the ensemble dataset. The VAE’s latent space
effectively encapsulated synoptic flow regimes as controlling factors,
aligning with the physical understanding of Taiwan’s local circulation.
The critical transition of flow regimes under the southeasterly synoptic
flow regimes is also well represented in the VAE’s latent space,
indicating that the VAE can learn the nonlinear characteristics of the
multiscale interaction of the lee vortex. We further construct a
reduced-order model for local circulation predictions under diverse
synoptic conditions. This physics-informed VAE ensures the accurate
prediction of the nonlinear characteristics of multiscale interactions
between synoptic flows and the turbulence induced by topography, thereby
accelerating the assessment of the local circulation responses under
various climate change scenarios.
Spatial and Temporal Patterns of Southern Ocean Ventilation
Authors: Styles Andrew F. , MacGilchrist Graeme A. , Bell Michael J. , Marshall David P.
Published: October 2023

Ocean ventilation translates atmospheric forcing into the ocean
interior. The Southern Ocean is an important ventilation site for heat
and carbon and is likely to influence the outcome of anthropogenic
climate change. We conduct an extensive backwards-in-time trajectory
experiment to identify spatial and temporal patterns of ventilation.
Temporally, almost all ventilation occurs between August and November.
Spatially, ‘hotspots’ of ventilation account for 60% of open-ocean
ventilation on a 30 year timescale; the remaining 40% ventilates in a
circumpolar pattern. The densest waters ventilate on the Antarctic
shelf, primarily near the Antarctic Peninsula (40%) and the west Ross
sea (20%); the remaining 40% is distributed across East Antarctica.
Shelf-ventilated waters experience significant densification outside of
the mixed layer.
Simulating moisture transport over the Tibetan Plateau in Summer across hydrostatic to non-hydrostatic scales with a global variable-resolution model
Authors: Li Gudongze , Zhao Chun , Xu Mingyue , Feng Jiawang , Zhong Lei , Li Rui , Fu Yunfei
Published: October 2023

Moisture transport in summer induces annual precipitation peak over the
Tibetan Plateau (TP) thus being one crucial sustentation of water cycle
between the TP and its surrounding areas. Simulating moisture transport
accurately over the TP remains uncertain for current numerical models
with one important influencing factor as horizontal resolution. In this
study, in order to investigate the difference in moisture transport at
resolutions from hydrostatic to non-hydrostatic scales, three
experiments are conducted for summer of 2015 using a global
variable-resolution model, including one with a globally quasi-uniform
resolution of 60 km (U60km) and two with regional refinements over the
TP at resolutions of 16 km (V16km) and 4 km (V4km), respectively. The
differences in moisture transport among three simulations are
significantly influenced by the changes in wind fields through the
Himalayas and eastern TP at two layers, 700~600 and
600~400 hPa, which is largely modulated by their
difference in large-scale circulations particularly monsoon depression.
At hydrostatic scale (from 60 km to 16 km), the monsoon depression is
slightly stronger and shifts northward along with the mid-latitude
westerlies, which is due to the combination of the sensitivity of
convection scheme to integrating timestep and different extents of
resolved dynamical processes at different resolutions. With horizontal
resolution increasing to convection-permitting scale (from 16 km to 4
km), the resolved moist convection along with its associated less latent
heat leads to weaker monsoon depression over the south of TP, which is
much larger than the resolution induced difference at hydrostatic scale.

A Computer-Based Analysis to Study the Effect of LCB Position on Ship Resistance in the Early Design Stage: A Case Study with a Fishing Vessel Hull
Authors: Xhaferaj Blenard
Published: October 2023

Minimising ship resistance is considered a crucial aspect of the design process, as it impacts fuel consumption during the operational phase, which in turn impacts financial and environmental aspects. Minimising the resistance is a complex issue, because different main geometrical characteristics of the hull, such as dimensional ratios, form coefficients, shape of sections and waterlines, longitudinal centre of buoyancy LCB, etc., may affect its value. In the early design stage, computational tools based on parametric models for the prediction of resistance can be used because they provide rapid evaluation of resistance within an acceptable accuracy level. The paper aims to present a computer-based methodology for studying the effect of LCB position on ship resistance at the early design stage. The tool used for the analyses is a software developed by the author based on regression models for the prediction of resistance. The methodology was illustrated with a case study analysis of a hull of the well-known Ridgely-Nevitt fishing vessel series. For the hull taken in consideration, the results of the analysis showed that the hull with the LCB positioned at −2% of the LPP aft amidships exhibited minimal resistance characteristics.

Good learning takes place when the teacher has media that is able to facilitate the learning process and with good learning media too, especially in mathematics. However, the application of learning using learning media has not been fully implemented by teachers, while students need the help of learning media to make the learning process more varied. Therefore, this development research has the intent and purpose of producing a product that can help teachers and students during the course of the learning process, especially in geometry transformation material. In this research, the development model used is the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). This research was conducted at SMP Negeri 14 Tambun Selatan with 31 class IX students as subjects. Data collection techniques were carried out by interviewing mathematics teachers and students, observing, and filling out questionnaires. The validation process to determine the validity of the module was carried out by 2 media experts and 2 material experts with an overall assessment result of 0.73 which was included in the feasible category. Meanwhile, according to student responses obtained through filling out the student response questionnaire, it is included in the good category with an overall rating of 0.76. According to the students, the developed e-module makes it easier for students to learn, especially in solving geometric transformation problems, both easy and difficult, using the help of the GeoGebra application program.

One of the difficulties in learning mathematics is anxiety. The level of anxiety can be seen from the students' responses in solving math problems. The process of minimizing these conditions in order to obtain better learning outcomes requires learning techniques that are in accordance with students' cognitive abilities. The learning technique that corresponds to this is the scaffolding technique. This study aims to analyze the factors that cause learning difficulties in mathematics in terms of math anxiety in the opportunity material for class X SMAN 2 Seunuddon and the results of applying scaffolding techniques to overcome the level of anxiety. The research approach is in the form of a qualitative descriptive type. X-2 grade students' research subjects. Data collection techniques used observation, tests, questionnaires, and interviews which were then analyzed using reduction, presentation and conclusion of data. Based on the test results, it was found that the difficulty of learning facts, concepts, operations and principles was 58%, 50%, 58% and 75%, respectively. Through interviews, it was found that the factors that caused students to experience learning difficulties were: difficulties in understanding the opportunity material, there were physical disturbances to students, lack of interest in studying mathematics, lack of self-motivation, teachers were less interesting in presenting material, lack of motivation from parents and inadequate facilities. Next, the scaffolding technique of the environmental provisions type was carried out. The test results after the technique was carried out found difficulty learning facts, concepts, operations and principles of 8%, 8%, 8% and 41%, respectively. Thus it was concluded that the use of scaffolding techniques of the environmental provisions type provided a significant reduction in students' difficulties caused by anxiety in working on word problems on probability material.

Nowadays, perfectionism in organizations is a popular topic in the scientific literature (Ocampo, Wang, Kiazad, Restubog, & Ashkanasy, 2020; Saklofske, Di Fabio, Svicher, & Smith, 2023; Steinert, Heim, & Leichsenring, 2021). Building on the research on the topic of perfectionism at individual level, the present study investigates how the leader’s other-oriented perfectionism influences followers’ workplace well-being and their job stress, and how the pressure to be performant moderates these relationships in the context of multiple team membership. In order to test the four proposed hypotheses, a quantitative predictive correlational research design was used. Our sample consisted of 155 Romanian employees. Our results indicate that the leader’s other-oriented perfectionism was not related to followers’ job stress. Surprisingly, this form of perfectionism positively related to followers’ workplace well-being. In addition, the pressure to be performant did not moderate the relationship between the leader’s other-oriented perfectionism, on one hand, and job stress and workplace well-being, on the other hand. These findings extend the literature on others-oriented perfectionism and well-being in the context of multiple team membership.
