The Implementation Usage of Youtube Media on Listening Ability of English Students During the Covid-19 Pandemic
Authors: Manihuruk Leonita Maria Efipanias , Nababan Irene Adryani
Published: January 2023

This research is motivated by learning English listening for students during the covid-19 pandemic which has not been carried out properly because students' understanding of listening skills is still lacking. The teaching and learning process during the pandemic is increasingly difficult for students to experience, resulting in disruption of the teaching and learning process. This also reduces the activeness of students in participating in listening learning. The learning media used are also still less effective, moreover the learning techniques used are still less varied. The purpose of this study was to determine the implementation of the use of Youtube media on the English listening skills of HKBP Nommensen Pematangsiantar University students during the covid-19 pandemic. The research method used is a quasi-experiment without a control class. The steps that will be carried out in this research are; 1) Conducting Pre Test; 2) Doing treatment using Youtube media; 3) Do a Post Test, then conclude. Learning outcomes can be seen how the differences in the increase in learning outcomes in the pretest and posttest can be seen. In the experimental class there was an increase in classical learning outcomes of 72,3287%. Conclusion from the research Overall, the implementation of the use of YouTube can be designed to be an effective learning medium for Transactional Listening tasks.
“Agora sei o que você faz, você conta histórias!”: notas etnográficas sobre um Diário de Campo Visual Público, alteridade, colonialidade e posicionalidade
Authors: Damásio Ana Clara
Published: January 2023

Em 2019 surgiu a ideia de realizar um "Diário de Campo Visual Público". O objetivo inicial era abrir uma conta em uma rede social de compartilhamento de fotografias (Instagram – perfil @diariodecampovisual) e todos os dias postar uma fotografia. Em campo realizado no primeiro semestre de 2019, em Canto do Buriti – PI, sobre curso de vida, foram produzidas e compartilhadas 90 fotografias em 90 dias. Algumas pessoas passaram a acompanhar as fotografias na rede social, como professoras, moradoras da cidade, familiares, alunas, pesquisadoras, meios de comunicação e políticos. Novas perguntas emergiram além da intenção inicial de "compartilhar" ou "devolver" fotografias, mas de torná-las "públicas" em conjunto com a temporalidade da pesquisa com reflexões ainda iniciais sobre o campo, as parentes-interlocutoras e a antropologia num sentido amplo do termo. Esse artigo se propõe a fazer uma reflexão do artesanal processo de realizar um "Diário de Campo Visual Público" na internet e seus dilemas, controvérsias, benesses, limites e potencialidades.
Casa Bamba: Ancestralidade, resistência e memória coletiva em um povoado de Córdoba, Argentina
Authors: Negruzzi Guido Andrés
Published: January 2023

Casa de Bamba é um local na Argentina em uma área serrana da província de Córdoba. Deve o seu nome a um relato baseado na provável presença de uma pessoa escravizada fugida chamada Bamba, que segundo as diversas narrativas teria residido numa caverna demolida no final de 1800 para abrir caminho ao trem. No presente artigo se indaga sobre a a denominação deste lugar, analisando alternativas impensáveis para o discurso hegemônico tais como a existência de quilombos na Argentina. Levanto também, a necessidade de refletir a partir do presente, integrando os debates que se desenvolvem no Brasil acerca da ressemantização na palavra quilombo, amplamente usada neste país e de uso cotidiano na
Argentina, para considerar uma das dimensões do território e sua relação com algumas categorias recentes, como “comunidade ancestral”, utilizada por uma parte dos habitantes de Casa Bamba para caracterizar seu povo.
“Para que haya cada vez menos en ese altar”: Repertorios públicos de duelo por un transfemicidio en la ciudad de Córdoba, Argentina
Authors: Brollo María Daniela
Published: January 2023

En este texto propongo un abordaje sobre el tratamiento público y colectivo del duelo ante un transfemicidio ocurrido en 2017 en la ciudad de Córdoba (Argentina), con énfasis en algunas de las movilizaciones impulsadas por la organización ATTTA (Asociación de Travestis, Transexuales y Transgéneros de Argentina). A partir de un enfoque etnográfico me ocuparé de acciones que comenzaron con el reclamo de justicia y la elaboración de altares en el marco de una celebración/homenaje, continuaron con acciones de visibilización por otros asesinatos o episodios de violencia y finalmente se complementaron con la demanda por leyes integrales que contemplen la inclusión, el cupo laboral y la reparación histórica a personas trans y travestis.

A new species, Phlegmacium ochraceosquamosum, is described from southwestern China based on morphological and molecular evidence. The new taxon is associated with subtropical fagaceous trees and is characterized by a combination of viscid pale yellow to ochraceous yellow pileus covered with ochraceous brown squamules and fibrils, cylindrical to clavate stipe with ochraceous brown fibrillose girdles, and elongate to subamygdaliform basidiospores. Four species, namely P. glaucopus, P. paracephalixum, P. patrickense, and P. violaceorubens, were first discovered in China. Additional vouchers for two species, namely P. caesiocolor and P. kytoevuorii very recently reported from China, were provided. Illustrated morphological descriptions and comparisons with closely related species are provided. The recognition of these species was further confirmed by phylogenetic analysis based on ITS sequences.
Photographic Visualization of Weather Forecasts with Generative Adversarial Networks
Authors: Sigg Christian , Cavallaro Flavia , Günther Tobias , Oswald Martin R.
Published: January 2023

Outdoor webcam images jointly visualize many aspects of the past and present weather, and since they are also easy to interpret, they are consulted by meteorologists and the general public alike. Weather forecasts, in contrast, are communicated as text, pictograms, or charts, each focusing on separate aspects of the future weather. We therefore introduce a method that uses photographic images to also visualize weather forecasts. This is a challenging task because photographic visualizations of weather forecasts should look real and match the predicted weather conditions, the transition from observation to forecast should be seamless, and there should be visual continuity between images for consecutive lead times. We use conditional generative adversarial networks to synthesize such visualizations. The generator network, conditioned on the analysis and the forecasting state of the numerical weather prediction (NWP) model, transforms the present camera image into the future. The discriminator network judges whether a given image is the real image of the future, or whether it has been synthesized. Training the two networks against each other results in a visualization method that scores well on all four evaluation criteria. We present results for three camera sites across Switzerland that differ in climatology and terrain. We show that even experts struggle to distinguish real from generated images, achieving only a 59% accuracy. The generated images match the atmospheric, ground, and illumination conditions visible in the true future images in 67% up to 99% of cases. Nowcasting sequences of generated images achieve a seamless transition from observation to forecast and attain good visual continuity.
The Relative Warming Rates of Heat Events and Median Days in the Pacific Northwest from Observations and a Regional Climate Model
Authors: Salathé Eric P. , Beggs Adrienne , McJunkin Chris , Sandhu Satveer
Published: January 2023

This paper examines the trends in hot summer days for the Pacific Northwest in observations and a regional climate model ensemble. Hot days are identified by the temperature threshold for several percentile values computed over 10-yr intervals (85th, 90th, and 95th percentiles and absolute maximum) to differentiate heat events of different intensities and are compared to the median temperature (50th percentile). For the stations analyzed, the observed rate of warming during hot days is not statistically different from the warming rate of median days since the 1950s. However, for projections to 2100, hot days show a statistically significant increase in the warming rate of the hottest days compared to the warming rate for median days. Depending on location, the 95th-percentile daily maximum temperature shows a warming rate of up to 0.2°C decade−1 above the median warming rate. The divergence in the trends of median and extreme temperature shows substantial regional variation depending on local terrain and coastlines. The warming trend during hot days is related to the unique circulation patterns during heat events, which respond to different feedbacks and amplifying effects in the land–atmosphere system from those that prevail during typical days. The regional climate model simulations are taken from an ensemble of the Weather Research and Forecasting (WRF) Model simulations forced by 12 global climate model simulations from phase 5 of the Climate Model Intercomparison Project (CMIP5) using the RCP8.5 emissions scenario and 12-km grid spacing.

Significance Statement

The heatwave of June 2021 had substantial societal and ecological impacts, illustrating vulnerability to record-shattering events. This paper addresses whether climate change can cause heat events in the Pacific Northwest to warm at a more rapid rate than typical days. Based on observations, in the recent past, the hottest days warmed at about the same rate as typical days in the recent past. However, results from a high-resolution climate model show a higher rate of warming during the warmest days relative to median days under the most aggressive future emissions scenario. This effect could cause heatwaves to become more intense relative to typical days by 2100, making adaptation to extreme events more difficult.
Energetics of Eddy–Mean Flow Interactions in the East Australian Current System
Authors: Li Junde , Roughan Moninya
Published: January 2023

Examining eddy–mean flow interactions in western boundary currents is crucial for understanding the mechanisms of mesoscale eddy generation and the role of eddies in the large-scale circulation. However, this analysis is lacking in the East Australian Current (EAC) system. Here we show the detailed three-dimensional structure of the eddy–mean flow interactions and energy budget in the EAC system. The energy reservoirs and conversions are greatest in the upper 500 m, with complex vertical structures. Strong mean kinetic energy is confined within a narrow band (24.5°–32.5°S) in the EAC jet. Most energy is contained in the eddy fields instead of the mean flow in the EAC typical separation and extension regions (south of 32.5°S). Strong barotropic instability is the primary source of eddy kinetic energy north of 36°S, while baroclinic instability dominates the eddy kinetic energy production in the EAC southern extension, which peaks in the subsurface. The mean flow transfers 5.22 GW of kinetic energy and 3.33 GW of available potential energy to the eddy field in the EAC typical separation region. The largest conversion term is from available potential energy conversion from the mean flow to the eddy field through baroclinic instability, dominating between 29° and 35.5°S. Nonlocal eddy–mean flow interactions also play a role in the energy exchange between the mean flow and the eddy fields. This study provides the mean state of the eddy–mean flow interactions in the EAC system, paving the way for further studies exploring seasonal and interannual variability and provides a baseline for assessing the impact of environmental change.
Monitoring anti-Xa Levels to Optimize Low-Molecular-Weight-Heparin Thromboprophylaxis in High-Risk Hospitalized Patients: A Stratified Meta-Analysis
Authors: John Sunil , Wilkinson Molly , Ho Kwok M.
Published: January 2023

It is uncertain whether monitoring or targeting anti-Xa levels is necessary when using low-molecular-weight-heparin (LMWH) to prevent venous thromboembolism (VTE). This stratified meta-analysis assessed whether monitoring trough or peak anti-Xa levels with LMWH dosing would reduce risk of VTE. Twelve non-randomized studies involving 3604 hospitalized patients met the inclusion criteria and were subject to meta-analysis. Eight studies assessed the association between VTE and peak anti-Xa levels (between .2 and .5 IU/ml) and four studies assessed the benefits of targeting the trough anti-Xa levels (>.1 IU/ml). Achieving an adequate peak or trough anti-Xa level was associated with a reduced risk of VTE (random-effects model odds ratio [OR] .52, 95% confidence interval [CI] .34-.77; P = .001, I2 = 30% and P-value for heterogeneity = .171) compared with using a fixed standard dose of LMWH. Targeting the trough level (OR .40, 95%CI 0.22–.75, P = .004) appeared to be more effective than targeting the peak level (OR .62, 95%CI 0.37–1.03, P = .066), although a formal interaction analysis did not confirm they were statistically different (ratio of ORs = 1.52, 95%CI 0.68–3.40; z score = 1.03, P = .306). Targeting a higher anti-Xa level did not appear to increase the risk of bleeding or transfusion (OR 1.20, 95%CI 0.46–3.17, P = .707).
Interruption Value Type and Source Matter in Different Phases of an Interruption Process: Emotional/Cognitive Impact and Neural Evidence
Authors: Zhou Xingchen , Patrick Rau Pei-Luen
Published: January 2023

Objective

To examine the effect of interruption value type (utilitarian, hedonic) and source (external, internal) in different phases of an interruption process.

Background

Prior studies on interruption mostly focused on the cognitive outcomes of utilitarian interruptions. Hedonic interruptions are common in life; however, they are not sufficiently explored through research. Hedonic value is closely associated with emotional experiences, and, in turn, influences behaviors. Moreover, the way the effect of values is moderated by interruptions initiated by intrinsic motives is worth exploring.

Method

A 2 × 2 mixed design experiment was conducted with 48 participants who were asked to respond to instant messages during the writing task. The interruption value was induced by work or non-work tasks. The interruption source was manipulated by providing an alert. Functional near-infrared spectroscopy, behavioral data, and subjective measurements were collected and analyzed.

Results

Hedonic interruptions increased emotional valence, while utilitarian interruptions decreased it. These effects were strengthened by internal interruptions. The effect of interruption value type on work exhaustion was also moderated by the source. Interruption value type and source influenced the attention allocation before an interruption occurred. Hedonic interruptions led to longer resumption lags, whereas utilitarian interruptions required longer interruption durations. Internal interruptions led to improved performance in the resumed task.

Conclusion

Interruption source modulate the effect of interruption value type, especially on emotional experience and attention allocation before an interruption occurs.

Application

Self-initiated hedonic interruptions have emotional benefits, while alerts for utilitarian interruptions will improve attention on the main task before interruptions.
Teacher Motivation and Self-Efficacy: How do Specific Motivations for Entering Teaching Relate to Teacher Self-Efficacy?
Authors: Calkins Leona , Wiens Peter , Parker Jessica , Tschinkel Rebecca
Published: January 2023

This study explores the motivations for becoming a teacher, teachers’ self-efficacy, and the relationship among motivations and teacher self-efficacy using data from the TALIS 2018. The data included responses from 1933 United States teachers with six or more years of teaching experience. Results indicate that motivations, which were more intrinsic and altruistic, for becoming a teacher are positively correlated to teacher self-efficacy of classroom management, instruction, student engagement, and multicultural classrooms. The largest relationship was between motivation and self-efficacy in multicultural classrooms; the smallest relationship was between motivation and self-efficacy of classroom management. Extrinsic motivations had limited relationships to self-efficacy.
Mystagogical Preaching as a Distinctively Theological Event
Authors: Strout Shawn
Published: January 2023

Misunderstandings about the event character of liturgy and preaching often lead to critiques of the assertion that they are theologia prima. Mystagogical preaching as a distinctively theological event can illuminate the inherent connection between liturgy and preaching as theologia prima. This article begins with an exposition of liturgy as a theological event, continues with preaching as a theological event, and therefore argues that mystagogical preaching is a distinctively theological event because it involves expounding on the very liturgical event in which it is occurring. Saint Augustine's “Sermon 272” is used as a case study.

The present study compared linguistic processes and eye movement among individuals diagnosed with oculomotor apraxia (OMA) and the influence of bilingualism on OMA. Four patients consisting of one male and three females were diagnosed with OMA, and a group of four healthy individuals, comprising two males and two females who were all right-hand dominant. Also, a group of four stroke patients without ocular apraxia. Findings show that pointing skills in both the first (L1) and second language (L2) have increased, demonstrating statistical significance ( P-value < .001 and P-value = .02, respectively). Also, simple commands over time have increased in L1 and L2, showing statistical significance ( P-value < .01 and P-value < .01, respectively). Naming skills in L1 have increased over time, demonstrating statistical insignificance ( P-value < .01). However, in L2, no statistically significant change was observed ( P-value = .08). This skill in L1 in patients with OMA was significantly reduced compared to the healthy control group ( P-value = .03). Still, patients with OMA showed no statistically significant difference from their healthy counterparts ( P-value = .15). The orthographic ability of patients in L1 during the study period did not statistically change significantly ( P-value = .11). This skill level in L1 between patients with OMA and the healthy control group did not show a statistically significant difference ( P-value = .06). Still, there was a statistically significant change in the healthy control group in L2 ( P-value < .01). These findings suggest that the bilingual does not reflect a general executive in attentional guidance but could reflect more efficient guidance only under specific tasks.
Domestic Violence During the Corona Pandemic: A Comparison of Pre-Pandemic and Pandemic Incidents of Domestic Violence in the Netherlands
Authors: van Koppen M. Vere , Bruggeman Mieke , Houston Rhianne , Harte Joke M.
Published: January 2023

There is a widespread fear that the measures as a consequence of the worldwide corona pandemic have led to a significant increase in domestic violence and child abuse. The current study uses criminal files from all incidents of domestic violence that were reported to the police in a relatively large city in the Netherlands during 3.5 months before the pandemic and the first 3.5 months from the start of the nationwide shutdown, to compare the characteristics of the incident, the suspect and victim, how the case was handled and the involvement of minors. Results show that levels of domestic violence during the Covid-19-related restrictions did not increase compared to before the pandemic. During the pandemic, suspects were relatively more often men, the violence was less often reciprocal, more often took place inside the homes of suspects and victims, and was more often reported to the police by a witness than before the pandemic. Before and during the pandemic, minors were involved in respectively 34% and 43% of the incidents, mainly as witnesses of the violence between their parents. The results of the study may ease the concerns about the potential threat of domestic violence levels going through the roof during isolating measures such as during a shutdown. Limitations of the study are that official data from a single, but large, city were used and that we were not able to control for seasonal effects.
Model Predictive Control for Full Autonomous Vehicle Overtaking
Authors: Lamouik Imad , Yahyaouy Ali , Sabri My Abdelouahed
Published: January 2023

Despite the many advancements in traffic safety, vehicle overtaking still poses significant challenges to both human drivers and autonomous vehicles, especially, how to evaluate the safety of passing a leading vehicle efficiently and reliably on a two-lane road. However, few realistic attempts in this field have been made in the literature to provide practical solutions without prior knowledge of the state of the environment and simplifications of vehicle models. These model simplifications make many of the proposed solutions in the literature unusable in real scenarios. Considering the dangers that can arise from performing a defective overtake and the substantial risk of vehicle crashes during high-speed maneuvers, in this paper we propose a system based on model predictive control to accurately estimate the safety of starting a vehicle overtake in addition to vehicle control during the maneuver that aims to ensure a collision-free overtake using a complete and realistic model of the vehicle’s dynamics. The system relies on a stereoscopic vision approach and machine learning techniques (YOLO and DeepSORT) to gather information about the environment such as lane width, lane center, and distance from neighboring vehicles. Furthermore, we propose a set of scenarios to test the performance of the proposed system based on accurate modeling of the environment under a range of traffic conditions and road architecture. The simulation result shows the high performance of the proposed system in ending collisions during overtaking and providing optimal pathing that minimizes travel time.
Developing a Chained Fisher Construction Cost Index for Structural Steel Girder Bridges
Authors: Okere George
Published: January 2023

The construction cost index is widely used by state departments of transportation (DOTs) for budgeting purposes, and to arrive at engineers’ estimates on projects for bid. State DOTs typically develop cost indexes at the construction program level. There is little information available on developing cost indexes for bridge types. This paper outlines how such a bridge-level cost index can be developed. The bridge-level cost index was developed from 19 weighted bid items aggregated into four weighted components (groups) of bid items, and then aggregated to the weighted bridge system. Using publicly available data from Ohio DOT, on historical bid items, chained Fisher indexes were developed for typical Ohio DOT structural steel girder bridges. In addition, forecasting beyond 2021 was computed using a well-fitted regression model. The findings from this research could help Ohio DOT to accurately estimate the cost to construct structural steel girder bridges based on price changes and price trends. In addition, the result of this research allows for long-term planning and budgeting of costs for similar bridge types within the state of Ohio. In their simplest form, the cost indexes generated from this research will help paint a picture of changes in the cost of construction from one specific year to another at a granular level. This research contributes to the body of knowledge by offering detailed steps on how to develop construction cost indexes at a granular level and specifically for structural steel girder bridges.
Development of an Artificial Neural Network-Based k-Value Prediction Model to Improve the Sensitivity of Base Layer on Rigid Pavement Performance
Authors: Saha Sajib , Gu Fan , Luo Xue , Lytton Robert L.
Published: January 2023

The performance of rigid pavement is greatly affected by the properties of the base/subbase and subgrade layer. However, the performance predicted by the AASHTOWare Pavement Mechanistic-Empirical (ME) Design shows low sensitivity to the properties of base and subgrade layers. In this study, a new set of modified models, that is, resilient modulus ( MR) and modulus of subgrade reaction ( k-value) are adopted to better reflect these layers’ influence on the overall performance. An artificial neural network (ANN) model is developed to predict the modified k-value based on finite element (FE) analysis. The training and validation data sets in the ANN model consist of 27,000 simulation cases with different combinations of pavement layer thickness, layer modulus, and slab-base interface bond ratio. Eight pavement section data are collected from the long-term pavement performance (LTPP) database and modeled using the FE software ISLAB2000 to evaluate the sensitivity of the modified MR model and k-values to pavement performance. The computational results indicate that the modified MR values have a higher sensitivity to water content in the base layer on fatigue cracking (bottom-up and top-down cracking) and the faulting performance of rigid pavements compared with the results using the Pavement ME design model. It is also observed that the k-values using the ANN model have a greater sensitivity to cracking and faulting performance as a result of changes in any bonded conditions (fully bonded, partially bonded, zero bonded), whereas the Pavement ME design model can only calculate at two extreme bonding conditions (i.e., fully bonded and zero bonded).
Adaptive Signal Control for Overflow Prevention at Isolated Intersections Based on Fuzzy Control
Authors: Yao Tianyu , Zhang Cheng , Zhao Jing , Gupta Ankit , Mondal Satyajit
Published: January 2023

Nonrecurrent congestion on urban roads may cause overflow, possibly leading to gridlock at intersections. Signal control is one of the most important measures to prevent such phenomena. For nonrecurrent congestion with uncertain bottleneck capacity, however, existing signal control methods have mainly adopted the strategy of cutting off the green signal of the overflow movement while the release priority of green time has not been considered. Consequently, the green time allocated to overflow movements is too long, aggravating overflow and congestion. Therefore, a signal control method is proposed to prevent overflow caused by uncertain bottleneck capacity. The proposed method extends existing real-time adaptive signal control to explicitly consider the risk of queue spillover. When an overflow risk is detected, the green times of overflow movements will be reassigned using fuzzy control to determine the release priority depending on the queue length and red time. Numerical studies were conducted for two scenarios with different downstream bottleneck capacities. The results demonstrate that the proposed method not only outperforms existing methods in respect of intersection efficiency but also reduces the risk of overflow. The proposed method achieves a 27.7% to 33.8% reduction in the maximum queue length of overflow movements compared with a traditional adaptive signal control method and a 10.9% to 11.0% decrease compared with a modified signal control method with a cutting-off strategy. The sensitivity analysis indicates that the average delay resulting from the proposed method is 51.1% and 18.0% less than the delays resulting from the traditional and modified methods, respectively.
Changes in Sports Activity After Periacetabular Osteotomy: A Qualitative and Quantitative Analysis
Authors: Leopold Vincent J. , Szarek Adrian , Hipfl Christian , Pumberger Matthias , Perka Carsten , Hardt Sebastian , Löchel Jannis
Published: January 2023

Background:

Patients undergoing periacetabular osteotomy (PAO) for symptomatic developmental dysplasia of the hip are usually young and active with high functional demands. Those who participate in sports seek surgical therapy to resume or maintain sports activities. There is little evidence regarding the postoperative level of activity and the extent to which sports activity changes after PAO both qualitatively and quantitatively.

Purpose:

The aim of this study was to determine the change in activity level as measured using the University of California Los Angeles (UCLA) activity score and the changes in qualitative and quantitative sports activity.

Study Design:

Case series; Level of evidence, 4.

Methods:

This was a retrospective analysis of prospectively collected data of 123 hips in 111 patients who underwent PAO for developmental dysplasia of the hip between January 2015 and June 2017. UCLA activity score, International Hip Outcome Tool 12, and Subjective Hip Value, as well as practiced sports, frequency and duration of sports activity, and time to return to sports, were assessed. Eventual changes in practiced sports and reasons for those changes were recorded.

Results:

Of the participating patients, 85% were female and 15% were male. The mean patient age at the time of surgery was 27.7 ± 7.3 years. Mean follow-up was 63 ± 10 months. UCLA score (5.08 ± 2.44 vs 6.95 ± 1.74; P < .001), International Hip Outcome Tool 12 (41.4 ± 22.2 vs 72.6 ± 22.9; P < .001), and Subjective Hip Value (42.8 ± 24.3 vs 80.4 ± 17.8; P < .001) increased significantly from pre- to postoperatively. Significantly more patients participated in low-impact sports postoperatively (31.7% vs 52%; P = .001). Participation in high-impact sports decreased (42.3% vs 36.6%; P = .361). The overall sports activity rate increased significantly (78.8% vs 90.8%; P = .008). Quantitatively, sports frequency in times per week ( P < .001) as well as length of exercise per time ( P = .007) increased significantly. A total of 52 patients (42%) changed sports activities postoperatively. Of these, 35 (28.4%) reported having stopped previously practiced sports after surgery, while 17 (13.8%) reported having started new sports. Reasons for starting and stopping certain sports varied and included hip- and non–hip related ones. In only 2 cases was physician’s advice given as a reason for changing the sport.

Conclusion:

Patients can improve their sports activity both qualitatively and quantitatively after PAO. However, a relevant proportion of patients adjusts their sports activities for a variety of hip-related and non–hip related reasons.
Experimental characterization and numerical modeling of in-plane shear behavior of woven prepreg composite fabrics
Authors: Yang Yunpei , Colton Jonathan
Published: January 2023

In-plane shear deformation is a highly important mechanic that controls the formation of wrinkles during the forming of textile composites. This paper presents two computational formulations that describe the in-plane shear behavior of woven thermoset prepreg fabric. The bias-extension characterization test was used to validate the computational models. One of the two computational models presented is based on linear visco-elasticity and the other is based on visco-hyperelasticity. The comparison of simulation and experiments shows that a visco-hyperelastic model is necessary to accurately capture the behavior of woven composite prepregs. This paper also compares the experimental measurements with calculations based on the pin-jointed net theory to develop a criterion that helps to determine the range of the bias-extension experiment data that can be used to validate and calibrate computational models.
Homework Expectancy Value Cost Scale for Middle School Students: A Validation Study
Authors: Xu Jianzhong
Published: January 2023

We investigated the psychometric properties of the Homework Expectancy Value Cost Scale (HEVCS), using 1,072 Chinese students in Grades 7–8. Results from confirmatory factor analyses (CFA) indicated that the HEVCS included three factors: Homework Expectancy, Homework Value, and Homework Cost. Additionally, no latent mean differences were found across gender and grade level. Furthermore, the HEVCS had adequate to very good reliability estimates. Finally, congruent with theoretical predictions, Homework Expectancy and Homework Value were related positively to homework effort, completion, and mathematics achievement, and negatively to homework procrastination. Homework Cost was related negatively to homework effort, completion, and mathematics achievement, and positively to homework procrastination. Our investigation provides compelling evidence that the HEVCS is a valid scale for assessing homework motivational beliefs.
Filling gaps in the nomological networks for dominance and affiliation by examining self-informant agreement on momentary interpersonal behavior
Authors: Ringwald Whitney R , Pilkonis Paul A , Wright Aidan GC
Published: January 2023

Interpersonal functioning involves an interplay of subjective perceptions and overt behavior. This study examines alignment between self and informant perceptions of momentary behavior to enrich the nomological networks for the domains of dominance and affiliation. We studied a sample of romantic couples ( N = 210 individuals) who rated their own and their partner’s interpersonal behavior during a 21-day ambulatory assessment (AA) protocol. We used multi-level structural equation modeling to estimate self-informant agreement on averages and variability of dominance and affiliation (between-person level) and on situational shifts in behavior (within-person level). We also examined convergence between self- and informant reported behavior measured by AA with cross-sectional self-report trait dominance, affiliation, and interpersonal problems. Results showed no self-informant agreement on dominance measured by AA, but moderate to strong agreement on affiliation at the between- and within-person levels. Self- and informant reported average affiliation measured by AA correlated with self-reports of trait affiliation, but only AA self-reports correlated with affiliation problems. Both self- and informant report dominance variability, and informant report affiliation variability, correlated with self-report interpersonal distress. Evidence for (mis)alignment in how dominance and affiliation are perceived by self and others have important implications for the role of these behaviors in everyday interpersonal functioning.
Obstacle avoidance trajectory planning strategy considering network communication constraints

In obstacle avoidance trajectory planning, the environmental information collected by onboard and roadside sensors must be transmitted to the intelligent vehicle controller through network communication such as the CAN network and DSRC. However, the inherent network communication constraints such as delay and loss will lead to obstacle avoidance errors. To this end, a game deep Q-learning (GDQN) obstacle avoidance strategy is proposed combining deep Q-learning and the game theory reward strategy. The deep Q-learning network realises the modelling and description of the uncertainty of communication constraints. The obstacle avoidance reward strategy is presented by integrating the rules of traffic environment and vehicle dynamics. A scene preprocessing algorithm based on the artificial potential field method is proposed, which transforms the search problem of the optimal obstacle avoidance trajectory in the global scene into the search in the banded area to reduce the demand for computing power to the greatest extent. The experimental results show that compared with the existing research, the proposed method effectively solves the obstacle avoidance trajectory planning problem when the network has communication constraints and effectively balances traffic safety and vehicle stability in the process of obstacle avoidance.

The magnetohydrodynamic flow of nanofluid is studied in the present analysis by using two parallel, rotating, and stretchable disks with a porous medium. The thermal radiation effects along with velocity slips at the interface of fluid and disk are considered in this work. The water is taken as base fluid, and carbon nanotubes (CNTs), titanium dioxide (TiO[Formula: see text]), and graphene oxide (GO) are taken as nanoparticles. The corresponding equations are modeled in terms of partial differential equations and Von Karman similarity transformation approach is adopted. The resulting equations are solved by using a finite difference method-based ND Solver. The axial, radial, and tangential velocity profiles and temperature distribution are discussed with graphs and tables. Thermal radiation and convective boundary conditions are used in the heat transfer process. When the thermal Biot number of the lower disk rises, fluid temperature enhances, whereas, the fluid temperature falls with the rise in the thermal Biot number of the lower disk. It is observed that when the thermal Biot number of lower disk rises from 0.5 to 0.8, heat transfer at lower disk is increased by about 6.66% in hexagonal-shaped CNTs-based nanofluid and 6.66% in spherical shaped TiO[Formula: see text] and GO-based nanofluid. The impact of physical parameters such as skin friction coefficient and Nusselt number are computed for governing parameters and discussed in detail.

Published: January 2023

In this work, a new control structure for fully actuated systems that solve the regulation and tracking of trajectories problem is proposed. This controller stands out for its ease of implementation and its ability to attenuate disturbances caused by parametric uncertainties and external forces. The control structure is based on the estimation of the delayed disturbances. Then, the current disturbance is canceled with the delayed disturbance, via the control input. The way in which the dynamics of the system is affected by the residual of these disturbances is analyzed. Also, the necessary conditions for establishing a reduced overshoot, settling time, and an attenuation factor of the disturbance are obtained. The performance of the proposed control structure is illustrated numerically by analyzing the behavior of different second-order single-input–single-output systems and also in the case of a RR-type robot. The control structure was also experimentally implemented in the case of a birotor type drone.

Urinary system disorders that occur at later ages are more common as the average human lifespan increases. Although urinary system disorders are widespread among elderly individuals, these disorders are seen in young people. The catheter system is used in some diseases such as urinary incontinence in the elderly. In addition, patients in different age groups who are hospitalized may need the catheter system during their treatment processes. In this study, a urine output monitoring system was designed and implemented to facilitate the tracking of the patient’s health situation. The designed control system was created based on the PIC18f45K22 microcontroller. The urine output monitoring system was created with a load cell, color sensor, buzzer, liquid crystal display screen, and Bluetooth communication units. A mechanical connection system was developed in which the urinary drainage bag attached to the catheter could be suspended to the control system by means of a hook. Thus, the developed system measured the weight of the urinary bag with a mean relative error value between 0.18% and 1.25%. The load cell–based created control system sensed the weight of the urinary catheter system and gave a warning when the urine in the drainage bag reached a predetermined weight. In addition, the optical density of the urine was measured, sent to the control unit using a wireless Bluetooth communication system, and classified on a 5-point scale to provide a simple visual indicator for caregivers to distinguish normal urine from urine requiring investigation. An audible warning was created using the microcontroller-based system in case of an emergency. The health condition of the patient was visualized through the designed interface program.

Objectives

To evaluate humoral and cell-mediated response after three doses of BNT162b2 SARS-CoV-2 vaccine in patients with systemic lupus erythematosus (SLE) treated with Belimumab (BLM).

Methods

SLE patients were vaccinated with three doses of BNT162b2-mRNA vaccine (two-dose primary vaccination, third booster dose after 6 months). The humoral immune response was assessed one and 6 months after the second dose (T1, T2), and 6 months after the booster dose (T3). Serological assay was performed (The Liaison® SARS-CoV-2 TrimericS IgG chemiluminescent). Spike-specific T-cell response was monitored 6 months after the second vaccine dose and the percentage of cytokines producing T cells was assessed by flow cytometry.

Results

Twelve patients [12F; median age 46 years (IQR 8.25); median disease duration 156 months (IQR 188)] were enrolled. At T1, all patients showed seroconversion (median anti-Spike IgG levels 1610 BAU/mL, IQR 1390). At T2––day of the third dose––a significant reduction of median anti-Spike IgG antibodies levels was observed [214 BAU/mL (IQR 94); p = 0.0009]. Anti-Spike IgG were significantly increased at T3, reaching a median value of 1440 BAU/mL (IQR 1316; p = 0.005). Despite declining humoral immunity, almost 60% of patients mounted a virus-specific CD4 + T-cell response 6 months after primary vaccination.

Conclusions

BLM does not impair humoral response to primary BNT162b2 SARS-CoV-2 vaccination. During the follow-up, a decline in antibody levels is evident and the third dose is crucial to increase the specific immune response. Finally, we observed a recall T-cell response to the Spike antigen 6 months after the first vaccination cycle.
Measurement Invariance and Differential Relationship to Substance Use of the Short UPPS-P Impulsive Behavior Scale Across Racial Groups

Published: January 2023

The Short UPPS-P Impulsive Behavior (SUPPS-P) scale assesses impulsive traits; however, its use among racial/ethnic minorities needs further testing. The aims of this study are to (a) test the measurement invariance of the SUPPS-P scale between White and racial/ethnic minority groups and (b) determine whether impulsive personality traits differentially relate to substance use outcomes across these groups. Participants were 1,301 young adults and recruited through a large public university or Amazon’s Mechanical Turk. Multigroup confirmatory factor analysis concluded strong measurement invariance for Black, Asian American, and Hispanic/Latino groups, each compared with a White group. Most relationships between SUPPS-P traits and substance use did not differ across the groups compared, although two differences emerged with alcohol use. The SUPPS-P can validly and reliably measure impulsive traits in Black, Hispanic/Latino, and Asian American young to middle adults. Previous findings on risk patterns with the SUPPS-P likely generalize to these groups.
