Over Time

Language is continuously changing. Words change their meaning over time and this process is known as semantic change. Change can occur both in the literal meaning and in the pragmatic use of words. In this research, semantic change is studied from a different perspective. Words that go through rapid semantic changes are the focus of this study. Users of English as a second language are also the focus of this study. The study observes whether these users are able to keep up with semantic change. It also gives us an idea regarding how much the users know about the multiple meanings of the same words. Another aspect of this study is to find out whether semantic change affects the comprehension of literature containing the words which went through semantic change. This research was conducted through a close-ended questionnaire designed by selecting fifteen words which changed their meaning over time. The respondents were fifty in number and were all females who had different educational backgrounds. The results were analyzed through pie charts. The results showed that the majority of ESL learners are able to keep up with semantic change, although a significant proportion is still struggling to understand the process. The results also showed that the learners of English as a second language have little knowledge of the previous meanings of words. If a word which has changed its meaning over time occurs in any literary work, ESL learners are not able to comprehend its meaning as it is intended to be understood. This can be considered as a negative attribute of semantic change. So, it was concluded that ESL learners are able to keep up with the change but most of them are unable to comprehend literature as it is intended to be understood.

AbstractBody-mass index (BMI), total cholesterol (TC), lowdensity lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglyceride (TG) levels are known to be highly heritable. We evaluated the genetic and environmental relationships of these measures over time in an analysis of twin pairs. Monozygotic (235 pairs) and dizygotic (260 pairs) male twins were participants in the National Heart Lung and Blood Institute Veteran Twin Study, and were followed with three clinical exams from mean age 48 years to mean age 63 years. Structural equation modeling (SEM) with adjustment forAPOEgenotype (a significant contributor to TC and LDL-C) was used to assess longitudinal patterns of heritability. Results indicated a contribution of genetic factors to BMI, TC, LDL-C, HLD-C, and TG. Modest increases over time were observed in the heritability of BMI (from 0.48 to 0.61), TC (from 0.46 to 0.57), LDL-C (from 0.49 to 0.64), and HDL-C (from 0.50 to 0.62), but this trend was not present for TG. There was a corresponding decrease in shared environmental influences over time for these traits, although shared environment was a significant contributor only for HDL-C. Moreover, we observed that genetic influences for all measures were significantly correlated over time, and we found no evidence of age-specific genetic effects. In summary, longitudinal analyses of twin data indicate that genetic factors do not account for a significant proportion of the variation in age-related changes of BMI or lipid and lipoprotein levels.

Auditory phonological processing skills are critical for successful reading development in English not only in native (L1) speakers but also in second language (L2) learners. However, the neural deficits of auditory phonological processing remain unknown in English-as-the-second-language (ESL) learners with reading difficulties. Here we investigated neural responses during spoken word rhyme judgments in typical and impaired ESL readers in China. The impaired readers showed comparable activation in the left superior temporal gyrus (LSTG), but reduced activation in the left inferior frontal gyrus (LIFG) and left fusiform and reduced connectivity between the LSTG and left fusiform when compared to typical readers. These findings suggest that impaired ESL readers have relative intact representations but impaired manipulation of phonology and reduced or absent automatic access to orthographic representations. This is consistent with previous findings in native English speakers and suggests a common neural mechanism underlying English impairment across the L1 and L2 learners.

While research on third language (L3) and multilingualism has recently shown remarkable growth, the fundamental question of what makes trilingualism special compared to bilingualism, and indeed monolingualism, continues to be evaded. In this contribution we consider whether there is such a thing as a true monolingual, and if there is a difference between dialects, styles, registers and languages. While linguistic and psycholinguistic studies suggest differences in the processing of a third, compared to the first or second language, neurolinguistic research has shown that generally the same areas of the brain are activated during language use in proficient multilinguals. It is concluded that while from traditional linguistic and psycholinguistic perspectives there are grounds to differentiate monolingual, bilingual and multilingual processing, a more dynamic perspective on language processing in which development over time is the core issue, leads to a questioning of the notion of languages as separate entities in the brain.

Truscott and Sharwood Smith (henceforth T&SS) attempt to show how second language acquisition can occur without any learning. In their APT model, change depends only on the tuning of innate principles through the normal course of processing of L2. There are some features of their model that I find attractive. Specifically, their acceptance of the concepts of competition and activation strength brings them in line with standard processing accounts like the Competition Model (Bates and MacWhinney, 1982; MacWhinney, 1987, in press). At the same time, their reliance on parameters as the core constructs guiding learning leaves this model squarely within the framework of Chomsky's theory of Principles and Parameters (P&P). As such, it stipulates that the specific functional categories of Universal Grammar serve as the fundamental guide to both first and second language acquisition. Like other accounts in the P&P framework, this model attempts to view second language acquisition as involving no real learning beyond the deductive process of parameter-setting based on the detection of certain triggers. The specific innovation of the APT model is that changes in activation strength during processing function as the trigger to the setting of parameters. Unlike other P&P models, APT does not set parameters in an absolute fashion, allowing their activation weight to change by the processing of new input over time. The use of the concept of activation in APT is far more restricted than its use in connectionist models that allow for Hebbian learning, self-organizing features maps, or back-propagation.

ABSTRACT Pulmonary damage caused by chronic colonization of the cystic fibrosis (CF) lung by microbial communities is the proximal cause of respiratory failure. While there has been an effort to document the microbiome of the CF lung in pediatric and adult patients, little is known regarding the developing microflora in infants. We examined the respiratory and intestinal microbiota development in infants with CF from birth to 21 months. Distinct genera dominated in the gut compared to those in the respiratory tract, yet some bacteria overlapped, demonstrating a core microbiota dominated by Veillonella and Streptococcus. Bacterial diversity increased significantly over time, with evidence of more rapidly acquired diversity in the respiratory tract. There was a high degree of concordance between the bacteria that were increasing or decreasing over time in both compartments; in particular, a significant proportion (14/16 genera) increasing in the gut were also increasing in the respiratory tract. For 7 genera, gut colonization presages their appearance in the respiratory tract. Clustering analysis of respiratory samples indicated profiles of bacteria associated with breast-feeding, and for gut samples, introduction of solid foods even after adjustment for the time at which the sample was collected. Furthermore, changes in diet also result in altered respiratory microflora, suggesting a link between nutrition and development of microbial communities in the respiratory tract. Our findings suggest that nutritional factors and gut colonization patterns are determinants of the microbial development of respiratory tract microbiota in infants with CF and present opportunities for early intervention in CF with altered dietary or probiotic strategies. IMPORTANCE While efforts have been focused on assessing the microbiome of pediatric and adult cystic fibrosis (CF) patients to understand how chronic colonization by these microbes contributes to pulmonary damage, little is known regarding the earliest development of respiratory and gut microflora in infants with CF. Our findings suggest that colonization of the respiratory tract by microbes is presaged by colonization of the gut and demonstrated a role of nutrition in development of the respiratory microflora. Thus, targeted dietary or probiotic strategies may be an effective means to change the course of the colonization of the CF lung and thereby improve patient outcomes.

Abstract This article continues the discussion on the nature of the early language of Buddhism and the language that the Buddha spoke, arguing that the received Pāli transmission evolved out of an earlier Middle Indic idiom, which is identified as a koine. Evidence for this koine can be found by examining correspondence sets within Pāli and its various varieties and by examining parallel, cognate correspondence sets between Pāli and other Prakrits which have survived. This article compares 30 correspondence sets transmitted in the Dhammapada recensions: the Gāndhārī Prakrit verses, the partially Sanskritized Pāli and Patna Dhammapada Prakrit verses, and the fully Sanskritized verses of the Udānavarga. By comparing cognate words, it demonstrates the existence of an underlying inter-language which in many cases can be shown to be the source of the phonological differences in the transmission. The paper includes a discussion on the two major factors of dialect change, evolution with variation over time, and the diffusionary, synchronic influence of dialect variation; it concludes that both are important, with dialect variation – and the phonological constraints of indigenous speakers who adopted MI as a second language – providing the pathways on which the natural evolutionary process was channeled.

Introduction: Stroke is the leading cause of long-term disability in adults, resulting in significant impairments in motor, sensory, and/ or cognitive that often requires continued rehabilitation services, which vary from intensive acute inpatient rehabilitation to outpatient rehabilitation services. Efforts to reduce disability have advanced rapidly over the past several years. Our data analysis was undertaken to assess whether recent changes in clinical practice have impacted the proportion of stroke patients receiving inpatient versus outpatient rehabilitation over time between 2014-2019 at our institution, which serves a diverse mix of rural, suburban, and urban populations. Methods: Our Institutional Review Board approved retrospective stroke database, including adult patients discharged to receive rehabilitation services data from 2014-2019, was used for analysis. Cochran-Armitage trend analysis was used to assess for differences type of rehabilitation services used over time and regression analysis was used to identify clinical factors associated with discharge type over time. Results: A total of 3467 patients were included in the analysis, 50% woman, 1% Asian, 20% Black, 75% White, 4% undetermined race, 17% intracerebral hemorrhage, 65% ischemic stroke, 11% subarachnoid hemorrhage, 3% transient ischemic attack, 3% other cerebrovascular disease. In this community population, 65% were discharged to inpatient rehab. Trend analysis demonstrated a significant increase in the proportion of patients being discharged home with rehab services, p<.0001. In comparison to those discharged home, patients discharged to rehab were older (odds ratio (OR) 1.02, confidence interval (CI) 1.02-1.03), with a higher NIHSS (OR 1.16, CI 1.14-1.18), discharged in 2014 (OR 1.72, CI 1.23-2.39) or 2016 (OR 1.46, CI 1.05-2.05) versus 2019. There was no association with race, gender, or discharge in 2015, 2017, or 2018. Discussion: Our findings demonstrate the community impact of recent changes in clinical practice guidelines for stroke. The increasing trend of home discharges is encouraging, but the significant proportion of those still not discharged home suggests there is still more work to be done to reduce stroke associated disability in adults.

Background and Purpose: Previous studies have demonstrated that the benefit of reperfusion therapy declines over time. The Clinical-Diffusion Mismatch (CDM) model has been suggested as surrogate for salvable tissue in acute ischemic stroke (AIS) patients. We sought to describe the temporal behavior profile of infarct volumes and CDM in patients suffering AIS due to proximal arterial occlusion (PAO). Methods: We performed a retrospective analysis of consecutive AIS patients admitted to two large academic institutions fulfilling the following criteria: (1) Baseline NIHSS ≥8; (2) PAO defined as MCA-M1, intracranial ICA, or tandem cervical + ICA/MCA-M1 occlusion on admission CTA/MRA; and (3) MRI-DWI performed ≤8 hours from time of stroke onset/last seen well (TSO). CDM was defined as baseline NIHSS ≥8 and DWI volume ≤25cc (as proposed by Davalos et al). Linear regression analysis was performed to define the changes on DWI lesion volume on presentation over time. The observed TSO to MRI were broken down into quartiles to look for any differences in the distribution of the baseline variables over time. Results: A total of 132 consecutive patients were identified (mean age, 66±16.8 years; 57% females; mean baseline NIHSS 17.5±5.3; occlusion site: MCA-M1, 64%; intracranial-ICA, 29%; tandem, 5%, mean TSO to DWI, 269.5±105.48 minutes). The mean DWI stroke volume on presentation was 46.7±54.8 cc (range, 0.19-436.1) and 63 (46.7%) patients had CDM. There was no significant changes in age, gender, baseline NIHSS, or occlusion site amongst the different time quartiles. Median infarct volume (cc) increased (quartile #1=8.5; #2=30.1; #3=38.5; #4=29.4) and the chances of having a CDM decreased (p<0.0001) across the different time quartiles. However, there was an overall poor correlation between DWI lesion volume on presentation and TSO to MRI (R-square=0.031, Figure ) and a significant proportion of the patients still had a CDM at later time epochs (#1=91.1%[20/22]; #2=47.8%[11/23]; #3=34.4%[21/61]; #4=42.3%[11/26]). Conclusions: Although infarct volume increases and the amount of penumbral tissue decreases over time, many patients with PAO will still have salvable penumbra at the later time epochs. This reflects individual differences in anatomic and physiological characteristics including the strength of collateral flow and highlights that selected patients may benefit from reperfusion therapy even at the later time windows.

IntroductionWaterpipe smoking continues to pose significant challenges to tobacco control efforts and many adolescent waterpipe smokers experience symptoms of nicotine dependence (ND). This study examined the predictors of progression of ND symptoms in adolescent waterpipe smokers.MethodsWe assembled a cohort of Lebanese adolescents enrolled in eighth and ninth grades at baseline, and surveyed them every 6 months over the next 24 months. Progression of ND symptoms was defined as an increase over time in the number of items endorsed on the Hooked on Nicotine Checklist. Predictors included individual (eg, psychological factors, attitudes towards waterpipe, school performance, physical activity) and socioenvironmental (eg, smoking among parents, siblings and close friends; the café environment) attributes.ResultsAmong 264 adolescent waterpipe smokers (baseline mean age=14.6 years, 50.4% females), 105 (39.7%) progressed on ND symptoms during follow-up. Predictors of progression were higher baseline stress (OR 1.11, 95% CI 1.03 to 1.19) and higher self-esteem (OR 1.14, 95% CI 1.05 to 1.24). Reporting difficulty refraining from smoking waterpipe while in a restaurant was the strongest predictor of progression (OR 4.04, 95% CI 1.44 to 11.34). Having a mother with ≥12 years of education protected against progression of ND (OR 0.46, 95% CI 0.21 to 0.99).ConclusionsA significant proportion of adolescent waterpipe smokers progressed on ND. Venue-based policies such as limiting youth access to waterpipe cafés are warranted.
