Abstract: The great variety of lead halide perovskite semiconductors represents an outstanding platform for studying crystal symmetry effects on the spin-dependent properties. Access to them is granted through optical orientation of exciton and carrier spins by circularly polarized photons. Here, the exciton spin polarization is investigated at $1.6$\,K cryogenic temperature in four lead halide perovskite crystals with different symmetries: (almost) cubic in FA$_{0.9}$Cs$_{0.1}$PbI$_{2.8}$Br$_{0.2}$ and FAPbBr$_3$, and orthorhombic in MAPbI$_3$ and CsPbBr$_3$. Giant optical orientation of 85\% is found for the excitons in FA$_{0.9}$Cs$_{0.1}$PbI$_{2.8}$Br$_{0.2}$, MAPbI$_3$, and CsPbBr$_3$, while it amounts to 20\% in FAPbBr$_3$. For all studied crystals, the optical orientation is robust to detuning of the laser photon energy from the exciton resonance, remaining constant for high energy detunings up to 0.3~eV, above which it continuously decreases to zero for detunings exceeding 1~eV. No acceleration of the spin relaxation for excitons with large kinetic energy is found in the cubic and orthorhombic crystals. This evidences the absence of the Dyakonov-Perel spin relaxation mechanism, which is based on the Rashba-Dresselhaus splitting of spin states at finite $k$-vectors. This indicates that the spatial inversion symmetry is maintained in perovskite crystals, independent of the cubic or orthorhombic phase.

2. Impact of Surface Reflections in Maritime Obstacle Detection

Author: Yalçın, Samed and Ekenel, Hazım Kemal
Subjects: Computer Science - Computer Vision and Pattern Recognition, I.5.4
Abstract: Maritime obstacle detection aims to detect possible obstacles for autonomous driving of unmanned surface vehicles. In the context of maritime obstacle detection, the water surface can act like a mirror on certain circumstances, causing reflections on imagery. Previous works have indicated surface reflections as a source of false positives for object detectors in maritime obstacle detection tasks. In this work, we show that surface reflections indeed adversely affect detector performance. We measure the effect of reflections by testing on two custom datasets, which we make publicly available. The first one contains imagery with reflections, while in the second reflections are inpainted. We show that the reflections reduce mAP by 1.2 to 9.6 points across various detectors. To remove false positives on reflections, we propose a novel filtering approach named Heatmap Based Sliding Filter. We show that the proposed method reduces the total number of false positives by 34.64% while minimally affecting true positives. We also conduct qualitative analysis and show that the proposed method indeed removes false positives on the reflections.

Abstract: We report the first measurement of the azimuthal anisotropy of J$/\psi$ at forward rapidity ($1.2<|\eta|<2.2$) in Au$+$Au collisions at $\sqrt{s_{_{NN}}}=200$ GeV at the Relativistic Heavy Ion Collider. The data were collected by the PHENIX experiment in 2014 and 2016 with integrated luminosity of 14.5~nb$^{-1}$. The second Fourier coefficient ($v_2$) of the azimuthal distribution of $J/\psi$ is determined as a function of the transverse momentum ($p_T$) using the event-plane method. The measurements were performed for several selections of collision centrality: 0\%--50\%, 10\%--60\%, and 10\%-40\%. We find that in all cases the values of $v_2(p_T)$, which quantify the elliptic flow of J$/\psi$, are consistent with zero. The results are consistent with measurements at midrapidity, indicating no significant elliptic flow of the J$/\psi$ within the quark-gluon-plasma medium at collision energies of $\sqrt{s_{_{NN}}}=200$ GeV., Comment: 369 authors from 72 institutions, 12 pages, 7 figures, 5 tables. v1 is version submitted to Physical Review C.

Abstract: We study the problem of finding curves of minimum pointwise-maximum arc-length derivative of curvature, here simply called curves of minimax spirality, among planar curves of fixed length with prescribed endpoints and tangents at the endpoints. We consider the case when simple bounds (constraints) are also imposed on the curvature along the curve. The curvature at the endpoints may or may not be specified. We prove via optimal control theory that the optimal curve is some concatenation of Euler spiral arcs, circular arcs, and straight line segments. When the curvature is not constrained (or when the curvature constraint does not become active), an optimal curve is only made up of a concatenation of Euler spiral arcs, unless the oriented endpoints lie in a line segment or a circular arc of the prescribed length, in which case the whole curve is either a straight line segment or a circular arc segment, respectively. We propose numerical methods and illustrate these methods and the results by means of three example problems of finding such curves., Comment: 23 pages

Abstract: The $J/\psi$ and $\psi(2S)$ charmonium states, composed of $c\bar{c}$ quark pairs and known since the 1970s, are widely believed to serve as ideal probes to test quantum chromodynamics in high-energy hadronic interactions. However, there is not yet a complete understanding of the charmonium-production mechanism. Recent measurements of $J/\psi$ production as a function of event charged-particle multiplicity at the collision energies of both the Large Hadron Collider (LHC) and the Relativistic Heavy Ion Collider (RHIC) show enhanced $J/\psi$ production yields with increasing multiplicity. One potential explanation for this type of dependence is multiparton interactions (MPI). We carry out the first measurements of self-normalized $J/\psi$ yields and the $\psi(2S)$ to $J/\psi$ ratio at both forward and backward rapidities as a function of self-normalized charged-particle multiplicity in $p$$+$$p$ collisions at $\sqrt{s}=200$ GeV. In addition, detailed {\sc pythia} studies tuned to RHIC energies were performed to investigate the MPI impacts. We find that the PHENIX data at RHIC are consistent with recent LHC measurements and can only be described by {\sc pythia} calculations that include MPI effects. The forward and backward $\psi(2S)$ to $J/\psi$ ratio, which serves as a unique and powerful approach to study final-state effects on charmonium production, is found to be less dependent on the charged-particle multiplicity., Comment: 301 authors from 69 institutions, 8 pages, 3 figures. v1 is version submitted to Physical Review D Letters.

7. 'I Wanted to Grow up to Be Strong Enough to Do All the Work and Help My Mother': Why Do Children Want to Grow up Rapid?

Author: Vakkas Yalcin
Abstract: A supportive environment is critical for individuals to protect their developmentally bio-psycho-socio-emotional health. This research was carried out to determine the possible causes of "desire for rapid growth", which is frequently seen in childhood, and the emotional states caused by "desire for rapid growth" in children, were carried out in a basic qualitative research design. The research participants are 60 undergraduate students who are preschool pre-service teachers. Within the scope of the study, data were collected through focus group discussion and documents, and the study's results were reached through content analysis, one of the qualitative analysis methods. Based on the study findings, participant showed long-term effects such as emotional emptiness, nostalgia, permanent emotional and social impact, and lastly, the "desire for rapid growth" is experienced, It was concluded that they had feelings of worthlessness, inferiority, anger, stuckness, and insecurity. In addition, among all participants, 56 has at least experienced once in their childhood the "desire for rapid growth".

Abstract: In this work, we study the system identification problem for parameterized non-linear systems using basis functions under adversarial attacks. Motivated by the LASSO-type estimators, we analyze the exact recovery property of a non-smooth estimator, which is generated by solving an embedded $\ell_1$-loss minimization problem. First, we derive necessary and sufficient conditions for the well-specifiedness of the estimator and the uniqueness of global solutions to the underlying optimization problem. Next, we provide exact recovery guarantees for the estimator under two different scenarios of boundedness and Lipschitz continuity of the basis functions. The non-asymptotic exact recovery is guaranteed with high probability, even when there are more severely corrupted data than clean data. Finally, we numerically illustrate the validity of our theory. This is the first study on the sample complexity analysis of a non-smooth estimator for the non-linear system identification problem., Comment: 33 pages

12. Spin relaxation of localized electrons in monolayer MoSe$_2$: importance of random effective magnetic fields

Abstract: We study the Hanle and spin polarization recovery effects on resident electrons in a monolayer MoSe$_2$ on EuS. We demonstrate that localized electrons provide the main contribution to the spin dynamics signal at low temperatures below 15~K for small magnetic fields of only a few mT. The spin relaxation of these electrons is determined by random effective magnetic fields due to a contact spin interaction, namely the hyperfine interaction with the nuclei in MoSe$_2$ or the exchange interaction with the magnetic ions of the EuS film. From the magnetic field angular dependence of the spin polarization we evaluate the anisotropy of the intervalley electron $g$-factor and the spin relaxation time. The non-zero in-plane $g$-factor $|g_x|\approx 0.1$, the value of which is comparable to its dispersion, is attributed to randomly localized electrons in the MoSe$_2$ layer., Comment: 6 pages, 4 figures

13. General Scintillation for Gaussian Beam Propagating through Oceanic Turbulence and UWOC System Performance Evaluation

Author: Li, Yuxuan, Yi, Xiang, Tao, Xinyue, Yalçın, Ata, Cheng, Mingjian, and Zhang, Lu
Subjects: Physics - Optics, Physics - Atmospheric and Oceanic Physics
Abstract: In this paper, we derive a general and exact closed-form expression of scintillation index (SI) for a Gaussian beam propagating through weak oceanic turbulence, based on the general oceanic turbulence optical power spectrum (OTOPS) and the Rytov theory. Our universal expression not only includes existing Rytov variances but also accounts for actual cases where the Kolmogorov microscale is non-zero. The correctness and accuracy of our derivation are verified through comparison with the published work under identical conditions. By utilizing our derived expressions, we analyze the impact of various beam, propagation and oceanic turbulence parameters on both SI and bit error rate (BER) performance of underwater wireless optical communication (UWOC) systems. Numerical results demonstrate that the relationship between the Kolmogorov microscale and SI is nonlinear. Additionally, considering that certain oceanic turbulence parameters are related to depth, we use temperature and salinity data from Argo buoy deployed in real oceans to investigate the dependence of SI on depth. Our findings will contribute to the design and optimization of UWOC systems.

Abstract: High-momentum two-particle correlations are a useful tool for studying jet-quenching effects in the quark-gluon plasma. Angular correlations between neutral-pion triggers and charged hadrons with transverse momenta in the range 4--12~GeV/$c$ and 0.5--7~GeV/$c$, respectively, have been measured by the PHENIX experiment in 2014 for Au$+$Au collisions at $\sqrt{s_{_{NN}}}=200$~GeV. Suppression is observed in the yield of high-momentum jet fragments opposite the trigger particle, which indicates jet suppression stemming from in-medium partonic energy loss, while enhancement is observed for low-momentum particles. The ratio and differences between the yield in Au$+$Au collisions and $p$$+$$p$ collisions, $I_{AA}$ and $\Delta_{AA}$, as a function of the trigger-hadron azimuthal separation, $\Delta\phi$, are measured for the first time at the Relativistic Heavy Ion Collider. These results better quantify how the yield of low-$p_T$ associated hadrons is enhanced at wide angle, which is crucial for studying energy loss as well as medium-response effects., Comment: 535 authors from 84 institutions, 12 pages, 8 figures. v2 is version accepted for publication in Physical Review C.

16. Discrete-Time I&I Adaptive Interconnection and Damping Passivity-Based Control for Nonlinearly Parameterized Port-Controlled Hamiltonian Systems

Author: Alkrunz, Mohammed and Yalcin, Yaprak
Subjects: Electrical Engineering and Systems Science - Systems and Control, 93
Abstract: In this paper, a discrete-time I&I-based adaptive IDA-PBC controller for uncertain nonlinearly parameterized port-controlled Hamiltonian systems (PCH), where the parameter uncertainties are assumed in the energy function, is constructed. A proper formulation for the uncertain system dynamics is established where the uncertainties appear in nonlinearly parameterized form in the gradient of the Hamiltonian function. The adaptive IDA-PBC controller is constructed considering this formulation. For the adaptation mechanism of the IDA-PBC controller, a discrete-time parameter estimator is derived based on the immersion and invariance (I&I) approach. A structure for a free design function in the I&I-based estimator is proposed including some other free design functions. If these free design functions are selected to satisfy some conditions, derived in this paper, the Lyapunov asymptotic stability of the estimator dynamics is guaranteed. Besides, assuming these conditions are satisfied, local asymptotic stability of the closed-loop system, in a sufficiently large set is shown. The proposed method is applied to the two physical system examples and the performance of the adaptive controller is tested by simulation. It is demonstrated that the performance of the certain IDA-PBC controller is maintained by the adaptive IDA-PBC controller successfully., Comment: 31 pages, 9 figures

17. Contextual Emotion Recognition using Large Vision Language Models

Author: Etesam, Yasaman, Yalçın, Özge Nilay, Zhang, Chuxuan, and Lim, Angelica
Subjects: Computer Science - Computer Vision and Pattern Recognition
Abstract: "How does the person in the bounding box feel?" Achieving human-level recognition of the apparent emotion of a person in real world situations remains an unsolved task in computer vision. Facial expressions are not enough: body pose, contextual knowledge, and commonsense reasoning all contribute to how humans perform this emotional theory of mind task. In this paper, we examine two major approaches enabled by recent large vision language models: 1) image captioning followed by a language-only LLM, and 2) vision language models, under zero-shot and fine-tuned setups. We evaluate the methods on the Emotions in Context (EMOTIC) dataset and demonstrate that a vision language model, fine-tuned even on a small dataset, can significantly outperform traditional baselines. The results of this work aim to help robots and agents perform emotionally sensitive decision-making and interaction in the future., Comment: 8 pages, website: https://yasaman-etesam.github.io/Contextual-Emotion-Recognition/. arXiv admin note: text overlap with arXiv:2310.19995

18. Quantum Ising Spin-Glass Otto Engine

Author: Tuncer, Aslı and Yalçın, Batu
Subjects: Quantum Physics
Abstract: We investigate a quantum Otto engine with a quantum Ising spin glass as the working medium to explore the scaling behavior of work output and thermodynamic performance concerning system size, particularly near the critical point. Specifically, we explore the two operating modes of the Otto engine, namely the heat engine and refrigerator modes. We observe a double-peaked structure in the heat engine regime, leading to superlinear scaling in both work output and thermodynamic performance near the critical point. Additionally, in the refrigerator regime, superlinear scaling in refrigerator efficiency can be achieved at high and low temperatures, significantly outperforming models with uniform Ising interactions. These findings suggest that disorder and frustration in quantum Ising spin-glass systems could significantly impact thermodynamic performance in quantum heat engines and refrigerators, potentially opening up new avenues for improvement., Comment: 11 pages, 18 figures

Author: Kaya, C. Yalçın, Noakes, Lyle, and Schrader, Philip
Subjects: Mathematics - Optimization and Control, 49J15, 49K15, 65K10, 90C30
Abstract: We consider the problem of finding curves of minimum pointwise-maximum curvature, i.e., curves of minimax curvature, among planar curves of fixed length with prescribed endpoints and tangents at the endpoints. We reformulate the problem in terms of optimal control and use the maximum principle, as well as some geometrical arguments, to produce a classification of the types of solutions. Using the classification, we devise a numerical method which reduces the infinite-dimensional optimization problem to a finite-dimensional problem with just six variables. The solution types, together with some further observations on optimality, are illustrated via numerical examples.

20. Jamming Intrusions in Extreme Bandwidth Communication: A Comprehensive Overview

Author: Priyadarshani, Richa, Park, Ki-Hong, Ata, Yalcin, and Alouini, Mohamed-Slim
Subjects: Computer Science - Information Theory
Abstract: As the evolution of wireless communication progresses towards 6G networks, extreme bandwidth communication (EBC) emerges as a key enabler to meet the ambitious key performance indicator set for this next-generation technology. 6G aims for peak data rates of 1 Tb/s, peak spectral efficiency of 60 b/s/Hz, maximum bandwidth of 100 GHz, and mobility support up to 1000 km/h, while maintaining a high level of security. The capability of 6G to manage enormous data volumes introduces heightened security vulnerabilities, such as jamming attacks, highlighting the critical need for in-depth research into jamming in EBC. Understanding these attacks is vital for developing robust countermeasures, ensuring 6G networks can maintain their integrity and reliability amidst these advanced threats. Recognizing the paramount importance of security in 6G applications, this survey paper explores prevalent jamming attacks and the corresponding countermeasures in EBC technologies such as millimeter wave, terahertz, free-space optical, and visible light communications. By comprehensively reviewing the literature on jamming in EBC, this survey paper aims to provide a valuable resource for researchers, engineers, and policymakers involved in the development and deployment of 6G networks. Understanding the nuances of jamming in different EBC technologies is essential for devising robust security mechanisms and ensuring the success of 6G communication systems in the face of emerging threats.

Author: Ortega, Miguel and Yalçın, Buse
Subjects: Mathematics - Differential Geometry, 53E10, 53C21, 53C50, 53C42
Abstract: In this study, we deal with non-degenerate translators of the mean curvature flow in the well-known hyperbolic Einstein's static universe. We classify translators foliated by horospheres and rotationally invariant ones, both space-like and time-like. For space-like translators, we show a uniqueness theorem as well as a result to extend an isometry of the boundary of the domain to the whole translator, under simple conditions. As an application, we obtain a characterization of the the bowl when the boundary is a ball, and of certain translators foliated by horospheres whose boundary is a rectangle.

Author: Akkoyun, Nida, Altun Yalcin, Sema, Cakir, Zehra, and Yalcin, Pasa
Abstract: The research explores the effect of STEM and STEM-based robotic activities on the development of students' perceptions of mental risk-taking and its predictors and their perceptions of inquiry learning skills related to science. A mixed method was applied in the research. Its sample consisted of 35 students in a high school of the Ministry of National Education in a medium-scale province of the Eastern Anatolia Region between the 2017-2018 educational year. The Scale for Perceptions of Mental Risk-taking in Science Learning and Its Predictors (SPMRSLIP) and the Scale for Perception of Inquiry Learning Skills for Science (SPILSS) were applied to obtain the quantitative data in the research. In addition, the focus group interview was held. The STEM and STEM-based robotic activities have been performed with the students for 14 weeks. In the findings obtained at the end of the research, no significant difference was determined between the perception pre-test and post-test scores related to mental risk-taking and its predictors in science learning. However, difference was found in the dimension of interest. It was found that there was a significant difference between the pre-test and post-test scores in the inquiry learning skills perception scale for science and the qualitative findings also supported this result. According to the results, it can be recommended that STEM and Robotic educations should be given in other grades.

41. ACP-ESM: A novel framework for classification of anticancer peptides using protein-oriented transformer approach

Author: Kilimci, Zeynep Hilal and Yalcin, Mustafa

Abstract: Anticancer peptides (ACPs) are a class of molecules that have gained significant attention in the field of cancer research and therapy. ACPs are short chains of amino acids, the building blocks of proteins, and they possess the ability to selectively target and kill cancer cells. One of the key advantages of ACPs is their ability to selectively target cancer cells while sparing healthy cells to a greater extent. This selectivity is often attributed to differences in the surface properties of cancer cells compared to normal cells. That is why ACPs are being investigated as potential candidates for cancer therapy. ACPs may be used alone or in combination with other treatment modalities like chemotherapy and radiation therapy. While ACPs hold promise as a novel approach to cancer treatment, there are challenges to overcome, including optimizing their stability, improving selectivity, and enhancing their delivery to cancer cells, continuous increasing in number of peptide sequences, developing a reliable and precise prediction model. In this work, we propose an efficient transformer-based framework to identify anticancer peptides for by performing accurate a reliable and precise prediction model. For this purpose, four different transformer models, namely ESM, ProtBert, BioBERT, and SciBERT are employed to detect anticancer peptides from amino acid sequences. To demonstrate the contribution of the proposed framework, extensive experiments are carried on widely-used datasets in the literature, two versions of AntiCp2, cACP-DeepGram, ACP-740. Experiment results show the usage of proposed model enhances classification accuracy when compared to the state-of-the-art studies. The proposed framework, ESM, exhibits 96.45 of accuracy for AntiCp2 dataset, 97.66 of accuracy for cACP-DeepGram dataset, and 88.51 of accuracy for ACP-740 dataset, thence determining new state-of-the-art.

42. Reversible Intrapore Redox Cycling of Platinum in Platinum-Ion-Exchanged HZSM‑5 Catalysts

Abstract: Isolated platinum(II) ions anchored at acid sites in the pores of zeolite HZSM-5, initially introduced by aqueous ion exchange, were reduced to form platinum nanoparticles that are stably dispersed with a narrow size distribution (1.3 ± 0.4 nm in average diameter). The nanoparticles were confined in reservoirs within the porous zeolite particles, as shown by electron beam tomography and the shape-selective catalysis of alkene hydrogenation. When the nanoparticles were oxidatively fragmented in dry air at elevated temperature, platinum returned to its initial in-pore atomically dispersed state with a charge of +2, as shown previously by X-ray absorption spectroscopy. The results determine the conditions under which platinum is retained within the pores of HZSM-5 particles during redox cycles that are characteristic of the reductive conditions of catalyst operation and the oxidative conditions of catalyst regeneration.

Abstract: The Circle of Willis (CoW) is an important network of arteries connecting major circulations of the brain. Its vascular architecture is believed to affect the risk, severity, and clinical outcome of serious neuro-vascular diseases. However, characterizing the highly variable CoW anatomy is still a manual and time-consuming expert task. The CoW is usually imaged by two angiographic imaging modalities, magnetic resonance angiography (MRA) and computed tomography angiography (CTA), but there exist limited public datasets with annotations on CoW anatomy, especially for CTA. Therefore we organized the TopCoW Challenge in 2023 with the release of an annotated CoW dataset. The TopCoW dataset was the first public dataset with voxel-level annotations for thirteen possible CoW vessel components, enabled by virtual-reality (VR) technology. It was also the first large dataset with paired MRA and CTA from the same patients. TopCoW challenge formalized the CoW characterization problem as a multiclass anatomical segmentation task with an emphasis on topological metrics. We invited submissions worldwide for the CoW segmentation task, which attracted over 140 registered participants from four continents. The top performing teams managed to segment many CoW components to Dice scores around 90%, but with lower scores for communicating arteries and rare variants. There were also topological mistakes for predictions with high Dice scores. Additional topological analysis revealed further areas for improvement in detecting certain CoW components and matching CoW variant topology accurately. TopCoW represented a first attempt at benchmarking the CoW anatomical segmentation task for MRA and CTA, both morphologically and topologically., Comment: 24 pages, 11 figures, 9 tables.

Abstract: The PHENIX experiment has performed a systematic study of identified charged-hadron ($\pi^\pm$, $K^\pm$, $p$, $\bar{p}$) production at midrapidity in $p$$+$Al, $^3$He$+$Au, Cu$+$Au collisions at $\sqrt{s_{_{NN}}}=200$ GeV and U$+$U collisions at $\sqrt{s_{_{NN}}}=193$ GeV. Identified charged-hadron invariant transverse-momentum ($p_T$) and transverse-mass ($m_T$) spectra are presented and interpreted in terms of radially expanding thermalized systems. The particle ratios of $K/\pi$ and $p/\pi$ have been measured in different centrality ranges of large (Cu$+$Au, U$+$U) and small ($p$$+$Al, $^3$He$+$Au) collision systems. The values of $K/\pi$ ratios measured in all considered collision systems were found to be consistent with those measured in $p$$+$$p$ collisions. However the values of $p/\pi$ ratios measured in large collision systems reach the values of $\approx0.6$, which is $\approx2$ times larger than in $p$$+$$p$ collisions. These results can be qualitatively understood in terms of the baryon enhancement expected from hadronization by recombination. Identified charged-hadron nuclear-modification factors ($R_{AB}$) are also presented. Enhancement of proton $R_{AB}$ values over meson $R_{AB}$ values was observed in central $^3$He$+$Au, Cu$+$Au, and U$+$U collisions. The proton $R_{AB}$ values measured in $p$$+$Al collision system were found to be consistent with $R_{AB}$ values of $\phi$, $\pi^\pm$, $K^\pm$, and $\pi^0$ mesons, which may indicate that the size of the system produced in $p$$+$Al collisions is too small for recombination to cause a noticeable increase in proton production., Comment: 480 authors from 78 institutions, 18 pages, 6 tables, 16 figures. v2 is version accepted for publication in Physical Review C.

47. Vulnerable Narcissism and Internet Addiction: Exploring Mediating Pathway through Vengeance

Author: Ozkan Cikrikci and Ragip Umit Yalcin
Abstract: The present study aimed to explore the mediating pathway on internet addiction through vengeance. The sample was consisted of 392 university students (N female = 242, 61.7% and N male = 150, 38.3%). The ages ranged between 18 and 35, with a mean age of 21.6 (SD = 1.95). The sample completed Young's Internet Addiction Test-Short Form, The Vengeance Scale, and Hypersensitive Narcissism Scale. According to mediation analysis results using structural equation modeling and bootstrapping, vengeance partially mediated vulnerable narcissism-internet addiction association. The results of the present study intimated the importance of the effects of individual differences and communication styles or preferences on internet addiction. The possible potential therapeutic power of vulnerable narcissism, which may lead to a direct increase in vengeance and an indirect increase in internet addiction through vengeance, appeared in line with this perspective. Finally, the results provided beneficial outcomes for clinical experts.

48. Determination of Reading Anxiety of Primary School 4th Grade Students

Author: Yalcin Bay
Abstract: One of the factors that emotionally affect the education-learning process is anxiety. Considering students' anxiety in teaching how to read and write, anxiety will positively contribute to effective and productive learning. This study aimed to determine the "Reading Anxiety" of primary school students. A 29-item "Reading Anxiety Scale" was developed based on the 42- item draft scale that Çeliktürk and Yamaç (2015) used in her research titled "Developing a Reading Anxiety Scale for Primary and Secondary School Students: Validity and Reliability Analysis." Çeliktürk and Yamaç permitted using the developed "Reading Anxiety Scale" in this study titled "Determination of Reading Anxiety of Primary School 4th-grade Students". Descriptive survey model was used in the study. This study was conducted with the voluntary participation of 1049 students attending the 4th grade of primary school in the central districts of Eskisehir (Odunpazari and Tepebasi). Convenience sampling determined the schools, and the data obtained were tabulated and interpreted using the SPSS program in the computer environment. The reliability coefficient of the 29-item reading anxiety scale was 0.957 (95.7%). Confirmatory Factor Analysis (CFA) was applied, and the acceptable fit of 0.90 [less than or equal to] CFI [less than or equal to] 0.95 was checked. Standardized factor loads were higher than 0.3 and at an acceptable level of fit. No significant difference was found regarding the district of the school, gender, and father's working status. However, there were significant differences in reading anxiety according to age, parents' education level, and mother's working status within the 95% confidence interval. Accordingly, it was concluded that students' age, parents' education level, and mothers' working status affect students' reading anxiety. However, no significant difference was found regarding the district of the school, gender, and fathers' working status. No significant difference was found between the reading anxiety levels of the students according to the district where the school is located, their gender and the working status of their fathers. It was determined that as the education level of the students' parents increased, the level of reading anxiety decreased. It was determined that the working status of the mothers of the students caused a significant difference between the reading anxiety levels, while the working status of the fathers did not cause a significant difference.

49. Student Webcam Behaviors and Beliefs: Emergent Norms, Student Performance, and Cultural Differences

Author: Dennen, Vanessa P., Yalcin, Yasin, Hur, Jaesung, and Screws, Bruce
Abstract: This study presents findings from a survey of 2298 university students from three countries (South Korea, Turkey, United States) focused on their use of and beliefs about webcams to support synchronous learning, including behaviors such as turning cameras on and multitasking. Additionally, it explores differences due to national culture, school achievement, and classroom seating preferences. As expected, findings show synchronous learning use increased during the pandemic. Student preferences for passive viewing behaviors are strong, along with preferences for keeping cameras off. Differences based on classroom seating preferences suggest that students who sit at the front are more likely than their peers to make decisions about webcam use based on involvement, attention, and preparedness. Cultural differences suggest different pedagogical expectations. Multitasking proved to be a complex behavior and is not always linked to poor achievement outcomes. This study has implications both for future research directions on synchronous learning, student webcam practices, and achievement and for how instructors design synchronous classes.
