Shifting focus through a small lens: Discursive and introspective perspectives on the emergence of L2 study emotions
Authors: Sampson Richard J.
Published: March 2022

While perennial in the research landscape, empirical work investigating second language (L2) study emotions has proliferated in the past ten years (Dewaele, 2019). Nevertheless, this article argues there is space for more holistic yet detailed, social yet individual perspectives when conducting such research. As one avenue, the paper explores the potential of a “small lens” approach (Ushioda, 2016) to delve into particular emotional events in situ from learner-internal and learner-external points of view. It details an example of such an approach put into practice, in which the author examined the emergence of emotionally significant episodes for English as a foreign language undergraduates in Japan during short conversation sessions. The research explored data from discursive (video-recordings and transcripts of short conversations) and introspective (learner journals) angles. As a result, it was possible to observe the ways in which students’ emotional moves were both afforded by and acted on those of the other through their social interactions, and through interactions with additional aspects of their ongoing psychologies and relationships. The article thus aims to promote further situated L2 emotion research examining the dynamic interplay between various aspects of learners’ psychologies and the co-formed social context.
Dynamic engagement in second language computer-mediated collaborative writing tasks: Does communication mode matter?
Authors: Aubrey Scott
Published: March 2022

This study takes a dynamic approach to investigating engagement, examining fluctuations in cognitive-affective variables at regular time intervals during online collaborative second language (L2) writing tasks. Using online conference software and online editing software, 16 university students who use English as an L2, completed two collaborative problem-solution L2 writing tasks in two communication modes: video-chat and text-chat. After each task, learners viewed videos of their performances in 12 three-minute segments and were asked to rate their engagement on two scales (interest, focus). They were then interviewed about their attributions for fluctuations in their ratings. Group-level analysis revealed that learners experienced significantly higher focus and interest during tasks performed in video-chat mode than text-chat mode. This was contrasted with an analysis from a dynamic perspective, which produced a more nuanced picture of individual engagement trajectories during the tasks. Dynamic patterns of engagement fell into either moderately steady, increasing, decreasing, or rollercoaster pattern categories. A content analysis of 32 interviews revealed four factors that accounted for changes in engagement during tasks: task design (e.g., task familiarity), task process (e.g., instances of collaboration), task condition (e.g., communication mode), and learner factors (e.g., perceptions of proficiency).
Exploring the predictive role of teacher immediacy and stroke behaviors in English as a foreign language university students’ academic burnout
Authors: Derakhshan Ali , Eslami Zohreh R. , Curle Samantha , Zhaleh Kiyana
Published: March 2022

To expand the literature on the rather new concept of student burnout, the present study examined the influence of teacher immediacy and stroke variables on English as a Foreign Language (EFL) students’ experience of burnout. To fulfill this aim, a group of 631 undergraduate EFL students from various universities in Iran answered questionnaires including the Immediacy Behavior Scale, the Student Stroke Scale, and the Maslach Burnout Inventory-Student Survey. The results of confirmatory factor analysis (CFA) of immediacy and burnout scales demonstrated the validity of the two scales in the Iranian EFL context. Subsequently, Pearson multiple correlation coefficients and structural equation modeling (SEM) were used to analyze the data. It was found that student burnout subscales negatively and significantly correlated with teacher immediacy and stroke subscales. Moreover, the results indicated that teacher immediacy and stroke variables, in combination with their subscales, could predict student burnout. On the whole, it can be concluded that teacher immediacy and stroke concepts, characterized as positive teacher interpersonal communication behaviors enhancing rapport and positive interaction between the teacher and students in EFL contexts, are potential preventers of negative student-related outcomes such as burnout.

and 𝛽 is a positive constant.
For solving this problem approximately, a symmetric three-layer semi-discrete scheme with respect to the temporal variable is applied, in which the value of a nonlinear term is taken at the middle point.
This approach allows us to find numerical solutions per temporal steps by inverting the linear operators.
In other words, applying this scheme, a system of linear ordinary differential equations is obtained.
The local convergence of the scheme is proved.
The results of numerical computations using this scheme for different test problems are given for which the Legendre–Galerkin spectral approximation is applied with respect to the spatial variable.
Discrete probability model-based method for recognition of multicomponent combustible gas explosion hazard sources
Authors: Ye Wenhua , Feng Yang , Chen Yangming
Published: March 2022

Aiming at the problems of poor sensitivity and low accuracy of traditional combustible gas explosion hazard identification methods, the discrete probability model was introduced to design a multicomponent combustible gas explosion hazard identification method. Fem3 model is selected to analyze the diffusion mode of multicomponent combustible gas, and the calculation formula of diffusion velocity is obtained. The explosion limit of multicomponent combustible gas was observed by means of test, and the upper limit of explosion concentration of multicomponent combustible gas was obtained. According to the characteristics of explosion, a multicomponent combustible gas explosion hazard identification device is designed. The discrete probability model is used to identify the explosion hazard of multicomponent combustible gas. Experimental results show that the proposed method greatly improves the recognition sensitivity and accuracy, which fully shows that the proposed method has a better detection effect.

Silicon was recovered from solar cell Si scraps through 42.5 mol% SiO2–42.5 mol% CaO–15 mol% Al2O3slag refining. The motion behaviors of Si3N4and SiC were observedin situand real-time using a high-temperature laser confocal microscope, and the recovery of Si through slag refining was carried out at 1,500°C for 30 min. Results indicated that both SiC and Si3N4inclusions were concentrated in the slag, and this work provides a clear framework for recycling and reusing solar cell Si scraps.
Health as a Purpose or as a Right – The Principle of Proportionality and the Measures Against the Covid-19 Pandemic
Authors: Ducatti Lino Machado Gabriel
Published: March 2022

The Covid-19 pandemic has given cause for serious restrictions of fundamental liberty rights. In the legal doctrine of fundamental rights, the classical tool for the assessment of the material constitutionality of interferences with fundamental rights is the principle of proportionality. Indeed, the material determinant of the principle of proportionality is the intensity of the intervention in the fundamental right. One preliminary question, however, is often underestimated: the question as to the constitutional status of the interests protected or promoted by the intervening measures. After outlining the structure of the principle of proportionality, this article investigates the constitutional status that the interests protected by Covid-19 measures might have: is the protection of people’s health merely a legitimate purpose or a right? Finally, this article shows, with recourse to decisions of the German and Brazilian Constitutional Courts, the implications that different classifications have for the principle of proportionality.
Heterocoagulation simulation of nano alumina and silica particle dispersion using discrete element method
Authors: Dodange Setare , Riahifar Reza , Raissi Babak , Yaghmaee Maziar S. , Alhaji Amir
Published: March 2022

Heterocoagulation in alumina–silica suspension is studied using 2-dimensional discrete element method simulations. Controlling the structure and stability of the binary suspensions via selecting the appropriate size of precursors is crucial in ceramics processing. Alumina and silica particles with a broad range of sizes and size ratios are investigated. The size and the size ratio determine the degree of heterocoagulation and impact the suspension’s structure. Analyzing simulation results shows that when the sizes of silica and alumina particles are comparable, and the radii of particles are below 300 nm, a chain-like structure is formed. In suspensions with high size asymmetry, smaller silica particles surround larger alumina particles, and the degree of heterocoagulation is dependent on the composition of the suspension. The results show that suspension composition can also be used to tune the heterocoagulation structure.

Integration of GNSS observations with volunteered geographic information for improved navigation performance
Authors: Hassan Tarek , Fath-Allah Tamer , Elhabiby Mohamed , Awad Alaa ElDin , El-Tokhey Mohamed
Published: March 2022

Pedestrian and vehicular navigation relies mainly on Global Navigation Satellite System (GNSS). Even if different navigation systems are integrated, GNSS positioning remains the core of any navigation process as it is the only system capable of providing independent solutions. However, in harsh environments, especially urban ones, GNSS signals are confronted by many obstructions causing the satellite signals to reach the receivers through reflected paths. These No-Line of Sight (NLOS) signals can affect the positioning accuracy significantly. This contribution proposes a new algorithm to detect and exclude these NLOS signals using 3D building models constructed from Volunteered Geographic Information (VGI). OpenStreetMap (OSM) and Google Earth (GE) data are combined to build the 3D models incorporated with GNSS signals in the algorithm. Real field data are used for testing and validation of the presented algorithm and strategy. The accuracy improvement, after exclusion of the NLOS signals, is evaluated employing phase-smoothed code observations. The results show that applying the proposed algorithm can improve the horizontal positioning accuracy remarkably. This improvement reaches 10.72 m, and the Root Mean Square Error (RMSE) drops by 1.64 m (46 % improvement) throughout the epochs with detected NLOS satellites. In addition, the improvement is analyzed in the Along-Track (AT) and Cross-Track (CT) directions. It reaches 6.89 m in the AT direction with a drop of 1.076 m in the RMSE value, while it reaches 8.64 m with a drop of 1.239 m in the RMSE value in the CT direction.

Published: March 2022

Objectives

To evaluate the association between low regional cerebral oxygen saturation (rScO2) and neurodevelopment in preterm infants classified as no brain injury (NBI).

Methods

We retrospectively reviewed data of rScO2 monitoring during the first 3 days of life of infants with a gestational age (GA)<28 weeks or birth weight (BW)<1,000 g, with and without brain injury (BI). BI was defined as intraventricular haemorrhage, cystic periventricular leukomalacia or cerebellar haemorrhage. Univariate and multivariate analyses were used to study the association of rScO2<55% for more than 10 h in the first 3 days of life (NIRS<55%>10H) and the 24 months neurodevelopment.

Results

Of the 185 patients who met the inclusion criteria, 31% were classified as BI infants and 69% NBI. BI compared to NBI infants had a significantly lower GA and a higher incidence of complications of prematurity. Mean rScO2 in the first 72 h of life was significantly lower in BI than NBI. NIRS<55%>10H in NBI patients was negatively associated with neurodevelopmental scores both at the univariate and multivariate analysis (p<0.05). NBI infants with NIRS<55%>10H were found to have lower systemic oxygenation than their counterparts with rScO2<55% for less than 10 h.

Conclusions

NIRS<55%>10H in NBI small preterm infants was found to be an independent predictor of neurodevelopment at 24 months and it was associated with low systemic saturation values.

Authors: Jonnalagadda Jagan Mohan
Published: March 2022

This article investigates a proposed new mathematical model that considers the infected individuals using various rate coefficients such as transmission, progression, recovery, and vaccination. The fact that the dynamic analysis is completely determined by the basic reproduction number is established. More specifically, local and global stabilities of the disease-free equilibrium and the endemic equilibrium are proved under certain parameter conditions when the basic reproduction number is below or above unity. A realistic computer simulation is performed for better understanding of the variations in trends of different compartments after the outbreak of the disease.

The role of neuroimmune interactions in musculoskeletal pain
Authors: Schaible Hans-Georg , Ebersberger Andrea , Natura Gabriel , Vazquez Enrique
Published: March 2022

Interactions of the immune system and the nociceptive system play an important role in the generation and maintenance of pain in musculoskeletal diseases and in disease development. In inflamed tissue peripheral nociceptive neurons are rendered hyperexcitable by proinflammatory cytokines, antigen/antibody complexes and other immune mediators. Spinal nociceptive neurons are rendered hyperexcitable with the support of microglial cells, the immune cells of the central nervous system. The so-elicited sensitization of pain pathways has a strong impact on pain processing in the brain. On the other hand, immune processes are regulated by the nervous system. Sensory neurons, by releasing neuropeptides, and efferent neurons of the sympathetic nervous system support immune processes which promote disease development.
On explaining stable dialect features: A real- and apparent-time study on the variable (en) in Austrian base dialects
Authors: Vergeiner Philip C. , Wallner Dominik
Published: March 2022

Referring to the so-called “actuation problem”, stability and change are two equally important problems in every theory of language change. However, apart from some exceptions, up to now studies predominantly focused on change, while stable linguistic features have been rarely considered. To address this desideratum and investigate factors that account for stability, the present article combines a real- and apparent-time analysis of the variable (en) in the Austrian base dialects by investigating data from 163 base dialect speakers from 40 locations across the country. The variable (en) occurs as a word-final ending in infinitive as well as in nominal forms, and – with respect to the preceding phonetic environment – shows a high degree of variation within and across all Austrian dialect areas. Although such a high degree of variation is considered a prerequisite for change, the analyses reveal a remarkable amount of stability for several variants of (en) in Austria. As will be argued, this fact can be attributed to both extra- and intralinguistic factors such as the variant’s areal distribution, its frequency, and morphological constraints.
Rewards versus Imprisonment: The Impact of Choice
Authors: Mungan Murat C.
Published: March 2022

Imprisonment and monetary rewards for non-convictions can similarly incentivize potential offenders to refrain from committing crime. Although imprisonment is expensive, it may still enjoy a cost advantage over rewards. This is because only detected criminals are imprisoned, whereas rewards need to be provided to the remaining, much larger, population. In this article, I demonstrate that the possible cost disadvantages of rewards are mitigated when people are offered a choice between an enforcement scheme involving no rewards and another involving rewards coupled with longer imprisonment sentences. Specifically, by using rewards in this manner, one can jointly reduce crime, time served per convict, and the tax burden of the criminal justice system, under the same conditions as one could by introducing rewards without choice in an environment where there is perfect detection. Moreover, monetary rewards provide incentives through wealth transfers, but imprisonment operates by destroying wealth. This leads choice-based reward regimes to be optimal unless the imprisonment elasticity of deterrence is higher than is empirically observed.

Straipsnyje aptariama bibliotekų personalo kvalifikacijos tobulinimo problematika. Akcentuojamos pasaulinės tendencijos, kai ypač aktualios yra IRT kompetencijos ir jų tobulinimas, nes padeda bibliotekoms teikti šiuolaikiškas ir aktualias paslaugas, kurios tenkina lankytojų ar jų paslaugų vartotojų poreikius bei lūkesčius. Lietuvoje laikomasi tokio paties požiūrio, tik bibliotekininkų kvalifikacijos ir IRT kompetencijų tobulinimas kol kas fragmentiškas, nenuoseklus, neindividualizuotas ir vykdomas daugiausia projektinių uždavinių bei finansavimo pagrindu. Nėra kriterijų ir metodikų, kurios padėtų nustatyti, kokias IRT kompetencijas bibliotekininkas yra įgijęs ir kokio jos lygio, kaip atsižvelgiant į tai planuoti jo kvalifikacijos tobulinimą. Lietuvoje neatlikta tyrimų, kurie būtų įvertinę, kokios IRT kompetencijos aktualiausios bibliotekininkams pareigų aspektu, atliekant kasdienes darbo funkcijas, kokio jos turi būti lygio, atsižvelgiant į pareigas, koks IRT kompetencijų poveikis visapusiškai tobulinant kvalifikaciją. Siekiant gerinti Klaipėdos regiono bibliotekininkų kvalifikacijos tobulinimo procesą ir spręsti šias problemas, vykdytas kokybinis ir kiekybinis tyrimas. Šiame straipsnyje dėmesys sutelktas ties kokybiniu tyrimu, kuris leido nustatyti, kad bibliotekininkų IRT kompetencijoms vertinti galima adaptuoti ne bibliotekoms skirtą metodiką, ja remiantis pateikti svarbiausių visoms pareigybėms IRT kompetencijų sąrašą, į kurį įtrauktos ir kompetencijos, padedančios visapusiškai tobulinti kvalifikaciją.

Scaling between subcomponents of folding and total brain volume (TBV) in healthy individuals (HIs) is allometric. It is unclear whether this is true in schizophrenia (SZ) or first-episode psychosis (FEP). This study confirmed normative allometric scaling norms in HIs using discovery and replication samples. Cross-sectional and longitudinal diagnostic differences in folding subcomponents were then assessed using an allometric framework. Structural imaging from a longitudinal (Sample 1: HI and SZ, nHI Baseline= 298, nSZ Baseline= 169, nHI Follow-up= 293, nSZ Follow-up= 168, totaling 1087 images, all individuals ≥ 2 images, age 16-69 years) and a cross-sectional sample (Sample 2: nHI= 61 and nFEP= 89, age 10-30 years), all human males and females, is leveraged to calculate global folding and its nested subcomponents: sulcation index (SI, total sulcal/cortical hull area) and determinants of sulcal area: sulcal length and sulcal depth. Scaling of SI, sulcal area, and sulcal length with TBV in SZ and FEP was allometric and did not differ from HIs. Longitudinal age trajectories demonstrated steeper loss of SI and sulcal area through adulthood in SZ. Longitudinal allometric analysis revealed that both annual change in SI and sulcal area was significantly stronger related to change in TBV in SZ compared with HIs. Our results detail the first evidence of the disproportionate contribution of changes in SI and sulcal area to TBV changes in SZ. Longitudinal allometric analysis of sulcal morphology provides deeper insight into lifespan trajectories of cortical folding in SZ.

SIGNIFICANCE STATEMENTPsychotic disorders are associated with deficits in cortical folding and brain size, but we lack knowledge of how these two morphometric features are related. We leverage cross-sectional and longitudinal samples in which we decompose folding into a set of nested subcomponents: sulcal and hull area, and sulcal depth and length. We reveal that, in both schizophrenia and first-episode psychosis, (1) scaling of subcomponents with brain size is different from expected scaling laws and (2) caution is warranted when interpreting results from traditional methods for brain size correction. Longitudinal allometric scaling points to loss of sulcal area as a principal contributor to loss of brain size in schizophrenia. These findings advance the understanding of cortical folding atypicalities in psychotic disorders.

The purpose of community service is to provide an understanding of asset assessment, measurement, and asset recognition through administrating the assets of Village Owned Enterprises (BUMDes). The methods of activities used are socialization, training and mentoring. The target community audience is the Director and manager of BUMDes Asung Daya and The Secretary of the Jatijajar Village bergas district of Semarang Regency. Socialization, training, and assistance in understanding the assessment, measurement, and recognition of assets run smoothly. BUMDes managers understand how to conduct asset valuations by using current market value. If the asset is a fixed asset, then its economic life is more than 12 months. If the asset is a current asset, then its economic life is less than 12 months. So far BUMDes has been able to compile financial statements correctly. However, some terms are not commonly used in accounting such as initial balance accounts, meaning the inventory of merchandise (beginning of the period). Recording of current assets in the form of inventory of merchandise in the asung daya minimarket is done computerized so that if you want to know the amount of stock just open on the cashier's computer.  The financial statements prepared are accounted for in village deliberations (musdes) attended by the Village Consultative Agency (BPD), women representatives, cadet corals, community leaders, BUMDes administrators, and village devices.

Tujuan pengabdian kepada masyarakat ini adalah memahamkan penilaian aset, pengukuran, dan pengakuan aset melalui pengadministrasian asset Badan Usaha Milik Desa (BUMDes). Metode kegiatan yang digunakan adalah sosialisasi, pelatihan dan pendampingan. Khalayak masyarakat sasarannya adalah Direktur dan pengurus BUMDes Asung Daya dan Sekretaris Desa Jatijajar Kecamatan Bergas Kabupaten Semarang. Kegiatan sosialisasi, pelatihan, dan pendampingan pemahaman penilaian, pengukuran, dan pengakuan aset berjalan dengan lancar. Pengurus BUMDes memahami cara melakukan penilaian aset dengan cara menggunakan nilai pasar saat ini. Jika aset tersebut adalah aset tetap, maka umur ekonomisnya lebih dari 12 bulan. Jika aset tersebut adalah aset lancar, maka umur ekonomisnya kurang dari 12 bulan. Selama ini BUMDes sudah dapat menyusun laporan keuangan dengan benar. Akan tetapi ada beberapa istilah yang tidak lazim digunakan dalam akuntansi semisal akun saldo awal, maksudnya adalah persediaan barang dagangan (awal periode). Pencatatan aset lancar berupa persediaan barang dagangan yang ada di minimarket asung daya dilakukan secara komputerisasi sehingga jika ingin mengetahui jumlah stok nya tinggal buka di komputer kasir.  Laporan keuangan yang disusun dipertanggungjawabkan dalam musyawarah desa (musdes) yang dihadiri oleh Badan Permusyawaratan Desa (BPD), perwakilan perempuan, karang taruna, tokoh masyarakat, pengurus BUMDes, dan perangkat desa.

OBJECTIVES

To describe the effects of the coronavirus disease 2019 (COVID-19) pandemic and associated practice shifts on consultation and referral patterns of an intimate partner violence program at a large, urban children’s hospital.

METHODS

Secondary data analyses examined COVID-19–related variations in patterns of consultations and referrals in the 11 months before the COVID-19 pandemic (April 1, 2019–February 29, 2020) and those after its emergence (April 1, 2020–February 28, 2021). χ2 analyses were used to examine differences in categorical outcomes of interest by time and practice setting, as well as differences within practice settings. Poisson regressions were used to compare the number of reasons for consultation and the number of referrals during the 2 periods.

RESULTS

Analyses revealed significant decreases in face-to-face consults (28% to 2%; P < .001) during the period after COVID-19 emergence alongside significant increases in the total number of consults (240 to 295; P < .001), primarily for emotional abuse (195 to 264; P = .007). Psychoeducation referrals also increased significantly (199 to 273; P < .001), whereas referrals to community resources decreased significantly (111 to 95; P < .001). Setting-specific analyses revealed that primary care settings were the only practice settings to demonstrate significant differences in overall number of and specific reasons for consultation and associated referral types before and after COVID-19 emergence.

CONCLUSIONS

Even during a shift away from face-to-face care, there was an increase in intimate partner violence referrals after the start of the COVID-19 pandemic. These findings suggest the importance of pediatric primary care as a location for survivors to access support.

Penelitian ini bertujan untuk mengetahui efektivitas pendekatan Realistic Mathematics Education (RME) dalam meningkatkan kemampuan literasi matematis siswa. Penelitian eksperimen dengan One-Group Pretest-Posttest Design ini dilakukan di MTs N Kota Kupang dengan siswa kelas VIII-H sebagai subjek penelitian. Tiga tahapan utama dalam penelitian ini adalah memberikan pretest literasi matematis, memeberikan pembelajaran matematika dengan pendekatan Realistic Mathematics Education (RME), dan memberikan posttest mengenai literasi matematis siswa. Instrumen yang digunakan adalah instrumen test tentang literasi matematis siswa sebanyak tiga soal essay materi kubus dan balok, baik pretest dan posttest menggunakan indikator soal yang sama, yang membedakan hanyalah redaksi soal. Teknik analisis data yang digunakan adalah uji t, namun sebelum dilakukan uji t, terlebih dahulu dilakukan uji Normalitas dan homogenitas sebagai syarat melakukan uji t. Hasil penelitian menunjukkan bahwa pada pretest tidak ada siswa yang tuntas KKM, pada posttest setelah diterapkan pendekatan RME diketahui bahwa sebagian besar siswa telah mencapai mencapai KKM dengan rata-rata hasil literasi matematisnya di atas nilai KKM. Data pretest dan posttest juga diketahui normal dan homogen sehingga dapat dilanjutkan dengan uji t, hasil uji t menunjukkan terdapat perbedaan rata-rata hasil literasi siswa setelah diterapkan pendekatan RME dalam pembelajaran matematika. Hasil penelitian juga menunjukkan peningkatan rata-rata literasi matematis siswa dari pretest ke posttest sebesar 42.83. Berdasarkan hal tersebut dapat dikatakan bahwa pendekatan RME efektiv dalam meningkatkan kemampuan literasi matematis siswa.
