Second language (L2) phonological acquisition is constrained by a complex interplay of extra-linguistic factors, among which the age factor is frequently investigated. This study adopted a multi-factorial approach to examine the effects of the age of learning English (AoLE), along with ten other extra-linguistic factors, on the ultimate English phonological attainment of 318 university students in Chinese context for English as a foreign language (EFL) as a whole and across three cohorts: first-year non-English majors, first-year English majors, and third-year English majors. The participants were administered background questionnaires and receptive and productive EFL phonology tests. The results of regression analyses indicated that the AoLE was not a predictor for the whole sample, while English pronunciation self-concept (EPSC) turned out to be the most predictive. Predictors for each cohort varied in number and content. Whichever cohort the participants came from, EPSC remained a constant and potent predictor, whereas the AoLE could merely predict the phonological attainment of first-year non-English majors, accounting for 4% of its variance. The findings of the study contribute to the long-standing debate over the viability of the critical period hypothesis, provide methodological implications for age-related L2 phonology research, and inform early EFL educational decisions.

Abstract Apart from their remarkable phonological skills young infants prior to their first birthday show ability to match the mouth articulation they see with the speech sounds they hear. They are able to detect the audiovisual conflict of speech and to selectively attend to articulating mouth depending on audiovisual congruency. Early audiovisual speech processing is an important aspect of language development, related not only to phonological knowledge, but also to language production during subsequent years. Th is article reviews recent experimental work delineating the complex developmental trajectory of audiovisual mismatch detection. Th e central issue is the role of age-related changes in visual scanning of audiovisual speech and the corresponding changes in neural signatures of audiovisual speech processing in the second half of the first year of life. Th is phenomenon is discussed in the context of recent theories of perceptual development and existing data on the neural organisation of the infant ‘social brain’.

Цель - изучение возрастных изменений толщины коры и ее слоев в парамедианной дольке мозжечка у детей. Материал и методы. Работа выполнена на постмортальном материале (62 мозжечка), полученном от детей в возрасте от рождения до 12 лет, умерших в результате травм без повреждений головного мозга. С помощью компьютерной морфометрии на окрашенных методом Ниссля фронтальных гистологических срезах коры, взятой билатерально в области парамедианной (тонкой) дольки (HVIIB) на вершине листков мозжечка, измеряли толщину коры, а также толщину ее молекулярного и зернистого слоев. Анализ количественных данных проводили в годовых интервалах. Результаты. В парамедианной дольке мозжечка увеличение толщины коры происходит в четыре этапа: в правом полушарии - от рождения к 1, 3, 5 и 9 годам, в левом полушарии - к 1, 5, 7 и 9 годам. Левосторонняя асимметрия толщины коры мозжечка отмечается у детей 1 и 2 лет, толщины молекулярного слоя - у детей 3 лет жизни. Правосторонняя асимметрия характерна для толщины зернистого слоя у детей 3 лет и поперечника коры, в целом, у детей 6 лет. Толщина коры и слоев в области парамедианной дольки мозжечка по среднегрупповым показателям достигает уровня взрослых людей к 9 годам. Выводы. Толщина коры мозжечка и ее слоев в области дольки H VII B увеличивается гетерохронно и гетеродинамически в правом и левом полушариях мозжечка у детей на первом году жизни, а также в периоды раннего, первого и второго детства. Уменьшения поперечника коры и слоев в парамедианной дольке мозжечка у детей от рождения до 12 лет не обнаружено. Objective - to study the age-related changes in the thickness of the cortex and its layers in the paramedian lobule of the cerebellum in children. Material and methods. The work was performed on postmortem material (62 cerebellums) obtained from children aged from birth to 12 years who died from injuries but without brain damage. The thickness of the cortex, as well as the thickness of its molecular and granular layers, were measured using computer morphometry on the Nissl-stained frontal histological sections of the cortex taken bilaterally in the region of the paramedian (gracile) lobule (HVIIB) at the top of the folia of cerebellum. Analysis of quantitative data was performed at annual intervals. Results. In the paramedian lobule of the cerebellum, the increase in the thickness of the cortex occured in four stages: in the right hemisphere - from birth to 1, 3, 5 and 9 years, in the left hemisphere - to 1, 5, 7 and 9 years. Left-sided asymmetry of the cortical thickness of the cerebellum was observed in 1 and 2-year old children, the thickness of the molecular layer - in 3-year old children. Right-sided asymmetry was characteristic for the thickness of the granular layer in 3-year old children and a cross-section of the cortex in 6-year old children. The thickness of the cortex and layers in the area of the paramedian lobule of the cerebellum on the average group indicators reached the level of adults by 9 years. Conclusions. The thickness of the cerebellar cortex and its layers in the area of the lobule HVIIB increased heterochronically and heterogeneously in the right and left hemispheres of the cerebellum in children of the first year of life, and in the periods of early, first and second childhood. No reduction in the diameter of the cortex and layers in the paramedian lobule of the cerebellum of children from birth to 12 years was found.

Purpose: This is a retrospective, single-center, non randomized interventional real life study, investigating the correlation between variability of central retinal thickness (CRT) and functional outcomes during 2 years of anti-VEGF therapy in patients treated for neovascular age related macular degeneration (nAMD). Background: CRT fluctuations can depend on various factors such as the correct timing of injections, the therapeutic algorithm, and the number of injections (NI) performed; it is important to understand if CRT fluctuations are responsible for worse visual outcomes and consequently to identify the correct ways to avoid or reduce them. Methods: Forty-one patients were treated for nAMD with aflibercept: 0.5 mg intravitreal aflibercept was administered every 4 weeks during the first 3 months, then bimonthly over the first year, and after the first year adopting a PRN regimen. Standard deviation of CRT (CRT/SD), BCVA, and NI were recorded. Correlation studies were performed by Pearson’s test, Ancova, and Principal Component Analysis. Results: A negative correlation was found between CRT/SD and final BCVA. In patients who lost more than 15 letters, CRT/SD mean was significantly higher in comparison with patients who lost less than 15 letters. Patients with final BCVA >65 letters showed lower CRT/SD values compared to patients with final BCVA ⩽65 letters. Multivariate analysis confirmed that in patients with higher baseline BCVA, improvement of BCVA was correlated to NI, and lower values of CRT fluctuations were observed. Conclusions: CRT fluctuations, even after an appropriate NI given per year, significantly influence BCVA; a proactive treatment algorithm appears crucial when treating patients with nAMD.

AimTo characterise macular neovascularisation (MNV) developing in eyes affected by geographic atrophy (GA).MethodsIn this multicentric longitudinal study involving three retina referral centres, patients previously affected by GA who developed an active MNV were included. Patients were investigated using structural optical coherence tomography (OCT), fundus autofluorescence, OCT-angiography and dye angiographies. Patients were treated with ProReNata antivascular endothelial growth factor (VEGF) injections and were revaluated after treatment.ResultsAmong 512 patients previously diagnosed with GA, 40 eyes of 40 patients (mean age 80.8±7.9 years, mean GA area 8.73±7.39 mm2) presented with treatment-naïve exudative MNV (accounting for an estimated prevalence of 7.81%; 5.49 to 10.13, 95% CIs) and thus were included in the analysis. 67.5% of MNVs were classified as type 2 MNV, 25% as type 1, 2.5% as type 3 and 5% as mixed phenotype. In 92.5% of cases, active MNV in GA showed subretinal hyperreflective material with or without evidence of subretinal/intraretinal hyporeflective exudation. During a mean follow-up of 28±25 months, patients were treated with 6.6±6.3 anti-VEGF injections, with 2.9±1.4 injections in the first year of treatment. No patient developed GA enlargement in the area of MNV.ConclusionsMNVs in GA showed different features and therapeutic response in comparison to previously reported features of MNV in age-related macular degeneration (AMD) without GA. For these reasons, the combined phenotype (ie, GA with neovascular AMD) should be considered as a distinct entity in the research and clinical setting.

Age And Sex

Sexual dimorphism and age-related differences are sources that contribute to morphologic and physiologic variation within animal populations. Measurement of animal performance may indicate whether this variation is functionally relevant. Our study aimed to experimentally test this statement in a captive population of House Sparrows ( Passer domesticus (L., 1758)) by examining age- and sex-related differences in escape response and its relationship to several morphological (tarsus, wing, tail lengths, and body mass) and physiological traits (cell-mediated immunity, natural antibodies, complement activity, hematocrit, and stress response). Escape response from a predator is considered a good variable to measure animal performance, because natural selection clearly favours individuals that avoid predators successfully. Our experimental design also aimed to standardize possible confounding factors affecting escape behaviour under natural conditions. We exposed sparrows to short episodes of high predation risk by simulating the attack of a predator and assumed that the capture order of individuals was related to their escape capacity. The optimal strategy was the immediate escape response for all individuals. We found that first-year males were the best escapers. In support of the hypothesis, juvenile males gathered a better optimum of several morphological and physiological characters that related to capture order.

Oral communication is essential for people’s workplace performance as well as for university students learning English. Speaking fluently is also crucial for maritime academy students prepared to work in industries abroad. Students need to believe in their ability to speak English. For this reason, sound communication skills are necessary for maritime students so they can compete with seafarer or sailor from other countries. The purpose of this research was to identify the level of oral communication apprehension of nautical students of Akademi Maritim Indonesia (Indonesian Maritime Academy) AIPI Makassar. The sample consisted of 10 first year students at nautical of AMI AIPI Makassar. Data was gathered through questionnaires adapted from Foreign Language Classroom Anxiety Class Scale (FLCAS). The findings indicated that students were generally apprehensive in EFL oral communication. The students showed the highest apprehension for public speaking. The level of nautical students’ apprehension based on observation and supported by the modified FLCAS were 20% in the low category, 60% in the moderate category, and 20% in the high category. Students in the high apprehension category showed more symptoms than students in the moderate and low apprehension categories.

<p>English listening is one of the five basic skills such as listening, speaking, reading, writing and translation that a Chinese postgraduate should acquire, and it is also the most significant one. In this study, 194 first-year postgraduate students at Shanghai University of Engineering Science were invited to report their strategies use and listening anxiety in the questionnaire with the 5-Likert Indirect Foreign Language Listening Strategies Scale and the 5-Likert Foreign Language Listening Anxiety Scale. The SPSS13.0 was used to analyze the descriptive statistics, reliability analysis, correlation analysis, Chi-square test and One-way ANOVA, which indicated a medium listening anxiety and a medium level of strategies use. Metacognitive strategies were more frequently used than social and affective strategies, the correlation between listening proficiency and listening anxiety was significantly negative, correlation between listening proficiency and indirect listening strategies was significantly positive, and that between indirect listening strategies and listening anxiety was significantly negative. Indirect listening strategies were useful to allay listening anxiety and would be incorporated into our normal classroom teaching.</p>
