Exploring well-being dynamics across career stages: Challenges and opportunities for EFL teachers
No full textThis session delves into the dynamic nature of well-being among English as a Foreign Language (EFL) teachers, examining how it changes across various career stages. In the context of an ever-evolving educational landscape with fast-technology improvements and pandemics, understanding the well-being challenges and opportunities faced by EFL teachers is crucial for promoting their professional development, personal satisfaction, workload, student dynamics, institutional support, and personal growth. Combining extensive research and real-life experiences, this study explores the features of well-being transitions from novice to experienced EFL colleagues. The paper will shed light on the opportunities within these challenges. It will emphasize the importance of mentorship, professional development, and self-care practices at different career stages to enhance well-being. The role of educational institutions and policymakers in fostering a supportive environment for EFL teachers will also be explored, ultimately benefiting both teachers and their students
Investigating the violation of charge-parity symmetry through top-quark chromoelectric dipole moments by using machine learning techniques
No full textThere are a number of studies in the literature on the search for Charge- Parity (CP) violating signals in top-quark productions at the LHC. In most of these studies, ChromoMagnetic Dipole Moments (CMDM) and ChromoElectric Dipole Moments (CEDM) of top quarks are bounded either by deviations from the Standard Model (SM) cross sections or by T-odd asymmetries in di-muon channels. However, the required precision on these cross section values is far beyond from that ATLAS or CMS experiments can reach. In this letter, the investigation of CEDM-based asymmetries in the semileptonic top-pair decays is presented as T-odd asymmetries in the CMS experiment. Expected asymmetry values are determined at the detector level using MadGraph5, Pythia 8, and Delphes softwares along with the discrimination of the signal and the background with Deep Neural Networks (DNN).SCOAP3 ; TÜBİTAKPublisher versio
Integration
No full textStrategic temporality permeates the integration experience of Turkey’s Syrians in a number of ways. First, given their temporary legal status, there is a grey area between reception and integration, which is highly symbolic of ambiguous inclusion (Kaya & Nagel, 2021). Until recently, there has been no publicly announced national integration policy; instead, there was only a discourse about uyum (social harmony) that is not premised on permanent inclusion or equal rights with locals. Further, refugees face liminality in every possible sphere governing long-term settlement, such as in the labour market, education, housing, health and citizenship. Most work informally and experience economic precarity; a third of Syrian children are not in school; refugees must secure their own (often substandard) housing; linguistic and other barriers prevent full health care access, and pathways to citizenship or long-term permanent residence are limited. All of this creates feelings of profound anxiety and uncertainty for refugees as they go about their day-to-day lives
Capacity planning for forming sustainable and cost-effective nanogrids
No full textThis paper proposes a new strategy for nanogrid capacity planning as a bilevel programming mathematical model with look-ahead logic. The first program, the Planner, is a linear program that solves for the optimal size of the Nano-grid comprising a PV solar system and a battery energy storage system. The second program, the Operator, is a mixed integer linear program that uses resultant sizes from the Planner and other data and then solves for the optimal asset dispatch on an hourly basis throughout the whole horizon. 24-hours is used as the main optimization window, to be consistent with real case operations of day-ahead scheduling but longer windows were also tested with the Lookahead (LA) logic. A sensitivity to LA logic was applied for an analysis conducted on cost-effectiveness, system sustainability, and local energy sufficiency. It was shown that implementing two days of LA logic reduces the import cost by 44%. Nano-grid was considered in this study to test the capacity planning strategy, but the methodology is also applicable to larger schemes
Size dependent change of mean square displacement in gold nanocrystals: A molecular dynamics simulation
No full textThermally activated atomic vibrations significantly decrease the x-ray diffraction intensities of nanocrystalline powders. Hence their quantification is critical for accurate structural characterization of small nanocrystals by x-ray diffraction. In this study, atomic vibrations in the form of mean square displacements (MSDs) in 5, 10, 15, 20, and 30 nm diameter spherical gold nanocrystals were computed by molecular dynamics (MD) simulations at room temperature and below. A strong size and temperature dependency of MSD was observed from spherical gold nanocrystals. Moreover, these displacements increased radially from the center of the nanocrystals and reached a maximum at the surface layers due to the presence of undercoordinated surface atoms and their relatively unrestricted motions. High temperature simulations were performed to investigate the evolution of structural stability of nanoparticles with increasing temperature. Surface melting was observed before complete melting of nanocrystals. Results of this work will be useful to understand the effect of nanocrystal size on the amplitude of thermally activated atomic vibrations and their quantification in measured intensities by x-ray diffraction experiments.TÜBİTA
Could head motions affect quality when viewing 360° videos?
No full textMeasuring quality accurately and quickly (preferably in real time) when streaming 360° videos is essential to enhance the user experience. Most quality-of-experience metrics have primarily used viewport quality as a simple surrogate for such experiences at a given time. While this baseline approach has been later augmented by some researchers using pupil and gaze tracking, head tracking has not been considered in enough detail. This article tackles whether head motions can influence the perception of 360° videos. Inspired by the latest research, this article conceptualizes a head-motion-aware metric for measuring viewport quality. A comparative study against existing head-motion-unaware metrics reveals sizeable differences. Motivated by this, we invite the community to research this topic further and substantiate the new metric's validity
Adaptive modulation for FSO IM/DD systems with multiple transmitters and receivers
No full textAtmospheric turbulence is a major impairment in free space optical (FSO) communication systems. Since turbulence induced fading exhibits quasi-static characteristics, reliable feedback of channel state information is possible allowing the implementation of adaptive transmission. In this letter, we consider multiple-input single-output (MISO) and single-input multiple-output (SIMO) FSO systems with pulse position modulation (PPM) and pulse amplitude modulation (PAM). We propose an adaptive algorithm where the modulation size/type is adjusted according to the channel fading conditions. We formulate the design of adaptive algorithm to maximize the spectral efficiency under peak and average power constraints while maintaining a targeted value of outage probability. We present extensive Monte Carlo simulations to demonstrate the performance of proposed adaptive scheme over turbulence channels
Havacılık emniyetine örgütsel bir bakış
No full textHavayolu taşımacılık modu, diğer taşımacılık modlarına kıyasla daha emni-yetli olarak bilinmektedir. Ancak emniyetli olmak sadece bir sonuç değil, arka planda pek çok emeğin sarf edilmesi anlamına gelmektedir. Emniyetli bir ta-şımacılık bir sonuçtan ziyade bir sürece işaret etmektedir ve pek çok payda-şın emniyeti düşünmesini ve emniyetli hareket etmesini gerektirmektedir. 1950’li yıllara kadar uzanan emniyeti etkileyen faktörlerin ortaya çıkarılması motivasyonu, günümüzde pek çok ilerleme kaydetmiş ve bir kültür inşası ile gerçekleşebileceği anlaşılmıştır. Emniyet kültürünün oluşması ve emniyet al-gısının içselleştirilmesi ile gelinecek nokta örgütlerin bulundukları bağlam özelinde değişse de bakış açısının kazandırıldığı ve emniyetli düşünme far-kındalığının arttığı söylenebilmektedir.
Ulusal ve uluslararası otoritelerin de yarattığı kurumsal baskılar ile günü-müzde emniyet kültürü, üzerinde düşünülmesi gereken, hayata geçilmesi noktasında sürekli emek sarf edilmesi gereken bir konudur. Hem uygulama-cıların hem de akademisyenlerin ilgisini çeken havacılık emniyeti, kitabın bu bölümünün ana temasıdır.
Bu çalışmada emniyet yönetim sistemi, emniyet kültürü, örgütsel güven ve kültürün yaygınlaşmasında önemli rol oynayan liderlik konuları, havacılık alanı özelinde ele alınmaktadır. Çalışmada aktarılan bilgiler, yazında yer alan çalışmalardan derlenmiş olup, uygulamacılar tarafından sıklıkla kullanılan uygulamaya dönük standart, regülasyon ve diğer yayınlar ile de desteklen-miştir
Association between performance-based and ratings of Turkish children’s executive function
No full textThis study is an examination of similarities and discrepancies between performance-based measures and ratings (parents and teachers) of executive function in children. Data were collected from 200 Turkish children (103 boys) and, their parents and teachers. Children’s ages ranged from 36 to 71 months (M = 54.01, SD = 9.65). Parents and teachers reported on children’s executive function using the Children's Behavior Questionnaire and Children’s Executive Functioning Inventory. We used eight structured tasks of The Executive Function Touch to assess children’s performance-based executive function. Primarily, based on confirmatory factor analysis, the unidimensional structure of the EF Touch was confirmed with Turkish children. Poor agreement between performance-based and ratings (parents and teachers) was found. In addition, there were also discrepancies between parents and teachers in their ratings of children’s executive function. These observed discrepancies highlight the importance of multi-informant measures of children’s executive function for comprehensive understanding
