Résumé :

L’apprendimento precoce delle lingue straniere – in particolare nella scuola primaria – è un processo affascinante ma complesso, fortemente condizionato dall’età degli allievi, dal contesto, dagli obiettivi specifici del ciclo scolastico e dalla didattica proposta. La fascia d’età è di fatto una delle variabili che più incide sullo sviluppo e sul sostegno delle competenze linguistiche, e richiede da parte dei docenti l’adattamento degli approcci adottati, delle attività proposte e dei materiali utilizzati per rispondere allo sviluppo cognitivo e emotivo degli allievi. Valutare i risultati dell’apprendimento in uno scenario di questo tipo è un processo delicato che deve essere monitorato con strumenti idonei che consentano di utilizzare la valutazione sia per comprenderne il valore aggiunto sia per sostenere l’apprendimento nel tempo. Questo contributo introduce le implicazioni dei risultati di alcuni studi longitudinali che hanno monitorato e valutato lo sviluppo delle competenze degli allievi e offerto spunti di riflessione sui processi di apprendimento.

Résumé :

Lo sviluppo e la applicazione delle tecniche percutanee per il trattamento dell'ernia del disco lombare hanno contribuito ad ampliare la scelta delle risorse non chirurgiche per la patologia correlata a questa condizione. La codifica delle indicazioni e la standardizzazione delle procedure hanno poi permesso di ottenere risultati univoci e soddisfacenti in termini di efficacia, come risulta dagli studi longitudinali in letteratura. La messa a punto di un protocollo di monitoraggio multidisciplinare, oggetto del presente lavoro, ha tuttavia messo a fuoco alcuni fenomeni (lombalgia postoperatoria e ridotta mobilità del rachide) la cui comprensione puó permettere, con opportuni provvedimenti riabilitativi, di ottimizzare il risultato dell'intervento nei casi non-responders o con insufficente risposta (circa il 20% dei casi trattati, anche in presenza di una soddisfacente evoluzione del quadro radiologico).

Résumé :

La resilienza allo stress ambientale č un fenomeno multidimensionale che puň manifestarsi durante l'etŕ evolutiva o al momento dell'esposizione allo stress durante la vita adulta. Da un punto di vista biologico, una precisa defi nizione di resilienza č necessaria per consentire il progresso della ricerca in quest'area. Inoltre, risulta importante defi nire qual č la risposta normale ad un evento traumatico. Alcune recenti ricerche hanno sottolineato il fatto che molte persone sono esposte a fattori di stress maggiori di altre senza peraltro sviluppare sintomi signifi cativi. Il substrato biologico di questa apparente mancanza di reattivitŕ č investigato al meglio in studi longitudinali con molteplici rilevazioni di dati. Appare interessante, comunque, il fatto che gli studi di neuroimaging abbiano suggerito la possibilitŕ che le esposizioni ad eventi traumatici non siano comunque a costo zero. In particolare, la neuroimaging di individui traumatizzati che non hanno sviluppato patologia sembra indicare alcune differenze nell'attivitŕ neurale rispetto ai controlli non esposti, indicativi del fatto che la resilienza potrebbe essere associata ad un crescente carico allostatico. Approcci promettenti per comprendere meglio la resilienza sono rappresentati dagli studi che esaminano l'interazione tra geni ed ambienti ad alto rischio. Particolarmente interessanti risultano i geni coinvolti nella risposta di allerta ed orientamento all'ambiente come pure i sintomi correlati al controllo esecutivo. Tuttavia, una comprensione ottimale della resilienza verrŕ dalla comprensione di quali geni incidano sulle reti neuronali e non su singole regioni del cervello o su isolati sistemi di neurotrasmettitori. Quindi da una prospettiva neurobiologica la resilienza deve essere vista come un processo longitudinale di adattamento, caratterizzato da fasi in cui l'adattabilitŕ puň avere delle accelerazioni e fasi in cui la funzione č compromessa.

Résumé :

Il presente lavoro esplora i legami temporali negli enunciati costituiti da 1 gesto e 1 parola durante il primo sviluppo comunicativo-linguistico, distinguendo tra combinazioni sin-crone e asincrone. Si analizza la produzione spontanea di 10 bambini singoli nati a termine e 2 pretermine, senza danno neurologico, osservati longitudinalmente nei primi due anni di età mediante videoregistrazioni delle interazioni a casa con la mamma, a cadenza mensile-bimensile tra 10-12 e 23-25 mesi, in accordo con la metodologia standard utilizzata negli studi sulla raccolta ed analisi delle produzioni spontanee. I risultati evidenziano che i bam-bini a termine con sviluppo tipico utilizzano un numero maggiore di combinazioni cross-modali sincrone, rispetto a quelle asincrone fin dalle prime fasi di sviluppo e in tutto il periodo osservato, dimostrando una precoce capacità di coarticolazione, sia semantica che temporale. Di contro, i bambini pretermine evidenziano una iniziale prevalenza di combina-zioni asincrone, rispetto a quelle sincrone, con un incremento successivo delle combinazioni sincrone durante il periodo osservato. Questo pattern evolutivo sembra più evidente nel bambino pretermine con più bassa età gestazionale (più prematuro). L'uso maggiore delle combinazioni asincrone su quelle sincrone, durante il secondo anno di età, potrebbe essere espressione di una condizione di rischio e di vulnerabilità che si esprime sia sul piano comunicativo-linguistico che socio-cognitivo tra i bambini pretermine senza danno neurologico nelle prime fasi di sviluppo. Considerando l'importanza del ruolo predittivo delle combinazioni di un gesto e una parola per le prime acquisizioni verbali, l'uso di una "multimo-dalità" poco coordinata sul piano temporale, durante il secondo anno di vita, potrebbe influire sui successivi processi di acquisizione. Tale dato rappresenta una conferma rispetto all'evidenza di profili di sviluppo disarmonici tra i bambini pretermine fin dalle prime ac-quisizioni.

Résumé :

Introduction: Anemia is a public health problem, prevalent among women of childbearing age. The aim was to determine the frequency of anemia in the first, second and third trimesters of pregnancy and to determine the associating factors in Algerian pregnant women. Methods: We conducted a prospective and longitudinal cohort study of 300 pregnant women from December 2013 to July 2016. All consenting women attending antenatal clinics and having undergone complete blood count (CBC) were included in the study. Sociodemographic characteristics, individual’s obstetrical history and the results of the CBC were collected. Anemia was defined according to the WHO criteria. After some descriptive statistics, we performed a bivariate analysis using the Chi-square test and Fisher exact probability test in order to determine the factors associated with gestational anemia. Results: The rate of anemia was 28.0 % in the first trimester, 32.3 % in the second and 54.2 % in the third one. It was more frequently observed during the third trimester of pregnancy (P < 0.05). No significant difference was found between gestational anemia and socio-demographic factors. Women with inadequate gain were more anemic (p = 0.01). The average concentration of hemoglobin, hematocrit, VGM and platelets were lower in anemic pregnant women (p < 0.0001). Conclusion: The prevalence of anemia during pregnancy remains high. A better management of chronic diseases in pregnant women and of postpartum follow-up is necessary to treat anemia before a subsequent pregnancy.

Résumé :

Since its inception, the intellectual capital (IC) framework, which developed from accounting and financial perspectives, focused primarily on firm-level analysis. There have been several important attempts in the literature to take IC to the macroeconomic level. The purpose of this paper is to assess the relationship between national intellectual capital, proxied with modified National Intellectual Capital Index (NICI) introduced by Bontis [7], and the Human Development Index (HDI), which became an important alternative to the traditional single dimensional measure of a country's development, like the gross domestic product [42]. The paper proposes a modified NICI suggested by Užienė [52]. The analysis includes panel data regression analysis for 12 countries. The dataset incorporated longitudinal data for weighted components of the NICI index for the period of 21 years (2000-2021). The results revealed that each of the elements of NICI, namely National Human Capital (NHC), National Market Capital (NMC), National Process Capital (NPC), and National Renewal Capital (NRC), exhibits significant impact on the levels of HDI in the said period. However, all elements, apart from NRC, show significant positive impact on HDI, pointing to the conclusion that these factors represent an important foundation for achieving and maintaining national competitiveness. Contrariwise, NRC was revealed to have the significant negative impact on HDI, opening the door to the question whether NRC is a real driver of national development, or just the effect of already reached development level.

Résumé :

Longitudinally welded steel pipe piles are not as commonly used as seamless steel pipe piles in offshore platform. Although longitudinally welded steel pipe piles are considerably cheaper than seamless steel pipe piles, yet many feared that longitudinally welded steel pipe piles are prone to fail because of non-uniformity in the heat affected zone (HAZ), especially when receiving impact loads during the installation process. In this paper, a finite element model is developed to study the deformation and failure of the longitudinal welded piles. Two modelling cases are performed: single and double piles, with two different failure parameters: maximum stress and maximum plastic displacement.

Résumé :

The aim of this study was to analyze the impact of being pain-affected and fear of falling on functional performance among nursing home residents, longitudinally. We used 6-month follow-up data from a cluster-randomized trial of 12 nursing homes (cluster level) with 239 nursing home residents at baseline (mean age, 95% confidence interval [CI] = 83.04 [81.40, 84.69], 70% women). The longitudinal analysis provided data on pain, fear of falling, functional mobility, and activities of daily living (individual level). The data revealed a trend indicating that pain-relieved nursing home residents showed better functional mobility over time. The results on fear of falling demonstrate obvious differences in the functional performance of nursing home residents cross-sectionally but not longitudinally. Nevertheless, the results underline the importance of an effective pain treatment to prevent decline in functional mobility among nursing home residents. Further longitudinal surveys are needed to verify the findings on functional performance.

Résumé :

Objective.To assess disability in systemic sclerosis (SSc) longitudinally and to identify disease-specific determinants, after accounting for informative patient dropout.Methods.We performed a multicenter, longitudinal study of 745 patients with SSc followed in the Canadian Scleroderma Research Group registry. Disability was assessed using the Health Assessment Questionnaire (HAQ). Longitudinal changes in disability were modeled using statistical approaches accounting for various levels of patient dropout.Results.In all the models, disability in SSc worsened over time. The magnitude of the worsening was small when patient dropout was assumed to be completely at random (increase in the HAQ of 0.022, 95% CI 0.002–0.042, per year). After accounting for different levels of informative patient dropout, the increase in the HAQ ranged from 0.039 (95% CI 0.018–0.061) per year to 0.071 (95% CI 0.048–0.094) per year. Thus, using the most conservative of these estimates, this was equivalent to an increase in the HAQ of 0.12 over 3 years. The disease correlates found to be most closely associated with disability were diffuse disease and breathing problems.Conclusion.Our study provides strong evidence that SSc causes increased disability over time, with breathing problems and disease type being the strongest predictors of disability. Statistical modeling accounting for informative patient dropout is necessary to properly assess the outcomes of patients followed longitudinally.

Résumé :

BackgroundDepression is a particular problem in older people and it is important to know how it affects and is affected by smoking cessation.AimsTo identify reciprocal, longitudinal relationships between smoking cessation and depression among older smokers.MethodAcross four waves, covering six years (2002–2008), changes in smoking status and depression, measured using the 8-item Centre for Epidemiologic Studies Depression Scale, were assessed among recent ex-smokers and smokers (n = 2375) in the English Longitudinal Study of Ageing.ResultsIn latent growth curve analysis, smoking at baseline predicted depression caseness longitudinally and vice versa. When both processes were modelled concurrently, depression predicted continued smoking longitudinally (B(β) = 0.21 (0.27); 95% CI = 0.08–0.35) but not the other way round. This was the case irrespective of mental health history and adjusting for a range of covariates.ConclusionsIn older smokers, depression appears to act as an important barrier to quitting, although quitting has no long-term impact on depression.

Résumé :

AbstractTo define metrics of phenotypic aging, it is essential to identify biological and environmental factors that influence the pace of aging. Previous attempts to develop aging metrics were hampered by cross-sectional designs and/or focused on younger populations. In the Baltimore Longitudinal Study of Aging (BLSA), we collected longitudinally across the adult age range a comprehensive list of phenotypes within four domains (body composition, energetics, homeostatic mechanisms and neurodegeneration/neuroplasticity) and functional outcomes. We integrated individual deviations from population trajectories into a global longitudinal phenotypic metric of aging and demonstrate that accelerated longitudinal phenotypic aging is associated with faster physical and cognitive decline, faster accumulation of multimorbidity and shorter survival. These associations are more robust compared with the use of phenotypic and epigenetic measurements at a single time point. Estimation of these metrics required repeated measures of multiple phenotypes over time but may uniquely facilitate the identification of mechanisms driving phenotypic aging and subsequent age-related functional decline.

Résumé :

Objective. Injury is the leading cause of death and long-term disability in children. Longitudinal cohorts are designed to follow subjects longitudinally in order to determine if early-life exposures are related to certain health outcomes. Methods. We conducted a systematic review to identify studies of children from birth through 5 years who were followed longitudinally with unintentional injury as an outcome of interest. Results. Of the 1892 unique references based on the search criteria, 12 (published between 2000 and 2013) were included. The studies varied on the population of focus, injury definition, and incidence rates. Existing studies that longitudinally follow children aged 0 to 5 years are limited in number, scope, and generalizability. Conclusions. Further study using population-based longitudinal cohorts is necessary to more comprehensively estimate incidence of injury in young children.

Résumé :

Abstract Background: Pubertal growth data in Thai children has been reported as cross-sectional studies. There is no longitudinal study in Thai children. Objective: Investigate the longitudinal growth data in normal Thai children including the relationship between age at pubertal onset and other growth parameters. Material and method: Eighty-eight normal children (44 boys, 44 girls) were longitudinally assessed for the growth and puberty until they reached their final adult height. Pubertal staging was assessed by the Tanner method. Results: Mean age of pubertal onset was 10.2 ± 1.2 years for girls and 12.2 ± 1.0 years for boys. Total pubertal height gain was 18.3 ± 4.0 cm for girls and 22.3 ± 4.4 cm for boys. Total pubertal height gain had a negative correlation with age at pubertal onset for girls, but not for boys. Conclusion: The onset of puberty was not much changed from previous studies. Girls with early puberty had a higher pubertal height gain. This might be due to a compensatory mechanism. These longitudinal growth data can be used as a reference in clinical practices for Thai children.

Résumé :

There is a dearth of longitudinal studies of corporate social responsibility expenditure (CSRE) and corporate governance in Bangladesh, which has been the impetus for this study. The study aims to identify the relationship between ownership structure and CSR expenditure. The empirical study considered a longitudinal period of 2007–2019 of listed financial firms (banks and non-banking financial institutions) of Bangladesh. The final sample consisted of 461 firm-year observations for 53 firms. The study incorporated a set of theories, including agency cost theory and stakeholder theory. The study applied the ordinary least square (OLS) regression technique to test hypotheses. The results of multiple regression analysis showed that foreign ownership and managerial ownership contribute positively and significantly to CSRE. However, the study did not document any relationship between institutional ownership and CSRE. The study used rigorous and alternative measurement techniques to further verify the findings. It was concluded that value creation from CSRE is highly dependent on the ownership structure of financial firms. The empirical study has significant theoretical and managerial implications.

Résumé :

Previous research cross-sectionally characterised eight morphological systolic blood pressure (SBP) active stand (AS) patterns using a clinical clustering approach at Wave 1 (W1) of the Irish Longitudinal Study on Ageing. We explored the longitudinal stability and clinical associations of these groupings at Wave 3 (W3), four years later. Eight AS groups had their clinical characteristics and AS patterns at W3 compared to W1. We explored longitudinal associations (new cognitive decline, falls, syncope, disability, and mortality) using multivariate logistic regression models. In total, 2938 participants (60% of Wave 1 sample) had adequate AS data from both W1 and 3 for analysis. We found no longitudinal stability of the eight AS groups or their morphological patterns between the waves. A pattern of impaired stabilisation and late deficit seemed more preserved and was seen in association with new cognitive decline (OR 1.63, 95% CI: 1.12–2.36, p = 0.011). An increase in antihypertensive usage seemed associated with reduced immediate SBP drops, improved AS patterns, and reduced orthostatic intolerance (OI). In pure longitudinal groups, AS patterns were not preserved after 4 years. AS patterns are longitudinally dynamic, and improvements after 4 years are possible even in the presence of higher antihypertensive burden.

Résumé :

Objective.To investigate whether trabecular bone loss is longitudinally associated with disease activity measures in patientswith axial spondyloarthritis (axSpA).Methods.Data from patients enrolled in the Incheon Saint Mary’s axSpA prospective observational cohort were evaluated. Trabecular bone loss was assessed using the trabecular bone score (TBS). The relationship between TBS and disease activity measures [Ankylosing Spondylitis Disease Activity Score (ASDAS), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP)] was investigated using generalized estimating equation (GEE) models.Results.Four-year followup data from 240 patients (80% males, mean age 37 ± 12 yrs) were evaluated. At baseline, higher disease activity according to ASDAS-ESR and ASDAS-CRP showed a trend toward lower TBS (p = 0.003 and p = 0.016, respectively). Univariate GEE analyses showed a significant association between TBS and disease activity measures over time, with the exception of BASDAI. Univariate analysis showed a longitudinal association between TBS and age, smoking, and spinal structural damage. In multivariate GEE analysis, ASDAS-ESR, ASDAS-CRP, ESR, and CRP were longitudinally associated with TBS after adjustment for confounding factors. ASDAS scores and inflammatory markers were longitudinally associated with TBS in patients with ankylosing spondylitis (AS; 79%), but not in patients with nonradiographic axSpA (nr-axSpA). BASDAI scores showed no relationship with TBS in either the AS or nr-axSpA groups.Conclusion.Trabecular bone loss in patients with axSpA, assessed using the TBS, showed a longitudinal association with ASDAS scores and inflammatory markers.

Résumé :

This article describes the design and phenotype and genotype data available for sibling pairs with varying genetic relatedness in the National Longitudinal Study of Adolescent Health (Add Health). Add Health is a nationally representative longitudinal study of over 20,000 adolescents in the United States in 1994–1995 who have been followed for 15 years into adulthood. The Add Health design included oversamples of more than 3,000 pairs of individuals with varying genetic resemblance, ranging from monozygotic twins, dizygotic twins, full siblings, half siblings, and unrelated siblings who were raised in the same household. Add Health sibling pairs are therefore nationally representative and followed longitudinally from early adolescence into adulthood with four in-home interviews during the period 1994–2009. Add Health has collected rich longitudinal social, behavioral, environmental, and biological data, as well as buccal cell DNA from all sample members, including sibling pairs. Add Health has an enlightened dissemination policy and to date has released phenotype and genotype data to more than 10,000 researchers in the scientific community.

Résumé :

Abstract Background Depressive symptoms and sleep disturbances disproportionately affect midlife women. While there may be a bidirectional association, few studies have examined whether depressive symptoms are longitudinally associated with subsequent sleep. Sleep is typically considered unidimensional, despite emerging evidence that multidimensional sleep health provides novel information on the sleep–health link. Purpose The current study examined whether higher depressive symptoms were longitudinally associated with poorer multidimensional sleep health. Method Depressive symptoms were assessed with the Center for Epidemiologic Studies Depression Scale across six to nine annual assessments in 302 midlife women from the Study of Women’s Health Across the Nation. Six months after their last assessment, actigraphy (mean ± standard deviation = 29.3 ± 6.9 days) and self-report were used to assess sleep health components: efficiency, duration, mid-sleep timing, regularity, alertness, and satisfaction, which were dichotomized and summed to create a composite multidimensional sleep health score. Mixed-effects models were used to evaluate the longitudinal associations between depressive symptoms and multidimensional sleep health, as well as individual sleep health components, adjusting for covariates. Exploratory analyses stratified models by race/ethnicity. Results Higher depressive symptoms were associated with subsequent poorer multidimensional sleep health (p < .0.001) and lower alertness (p < .0001) and satisfaction with sleep (p < .0001). Conclusions Our finding that higher average depressive symptoms were associated longitudinally with actigraphy-measured poorer sleep health in midlife women is novel and converges with the larger body of evidence that these two common symptoms are strongly associated. The bidirectional relationship between these two prevalent symptoms needs to be studied in prospective longitudinal studies.

Résumé :

RÉSUMÉLe recrutement et la rétention réussis lors d’études longitudinales basées sur la population exigent la compréhension des facilitants et des barrières à la participation. Les points de vue des Canadiens(nes) concernant une telle étude proposée, l’Étude longitudinale canadienne sur le vieillissement (ÉLCV), ont été explorés. Des groupes de discussion de participants âgés de ≥ 40 ans ont été mis en place dans six emplacements proposés pour la collecte de données de l’ÉLCV (Halifax, Montréal, Hamilton, Winnipeg, Calgary et Vancouver) pour discuter de la participation possible à une étude à long terme sur le vieillissement en santé. Il y avait un soutien marqué pour la recherche longitudinale sur la santé et le vieillissement. L’altruisme était une motivation clée à la participation et les universités ont été perçues comme des institutions crédibles pour entreprendre de telles études. Les participants ont eu peu d’inquiétude à l’égard du don d’échantillons biologiques, mais ont exprimé quelques inquiétudes concernant l’utilisation inapproprié du matériel génétique, la commercialisation des données de participant et les questions reliées à la confidentialité et la vie privée. Ces résultats ont déjà eu un impact sur le travail actuel, et futur, de l’ÉLCV, et fourniront également des informations utiles aux chercheurs qui entreprennent d’autres études longitudinales basées sur la population.

Résumé :

Background The COVID-19 pandemic has resulted in a high degree of psychological distress among health care workers (HCWs). There is a need to characterize which HCWs are at an increased risk of developing psychological effects from the pandemic. Given the differences in the response of individuals to stress, an analysis of both the perceived and physiological consequences of stressors can provide a comprehensive evaluation of its impact. Objective This study aimed to determine characteristics associated with longitudinal perceived stress in HCWs and to assess whether changes in heart rate variability (HRV), a marker of autonomic nervous system function, are associated with features protective against longitudinal stress. Methods HCWs across 7 hospitals in New York City, NY, were prospectively followed in an ongoing observational digital study using the custom Warrior Watch Study app. Participants wore an Apple Watch for the duration of the study to measure HRV throughout the follow-up period. Surveys measuring perceived stress, resilience, emotional support, quality of life, and optimism were collected at baseline and longitudinally. Results A total of 361 participants (mean age 36.8, SD 10.1 years; female: n=246, 69.3%) were enrolled. Multivariate analysis found New York City’s COVID-19 case count to be associated with increased longitudinal stress (P=.008). Baseline emotional support, quality of life, and resilience were associated with decreased longitudinal stress (P<.001). A significant reduction in stress during the 4-week period after COVID-19 diagnosis was observed in the highest tertial of emotional support (P=.03) and resilience (P=.006). Participants in the highest tertial of baseline emotional support and resilience had a significantly different circadian pattern of longitudinally collected HRV compared to subjects in the low or medium tertial. Conclusions High resilience, emotional support, and quality of life place HCWs at reduced risk of longitudinal perceived stress and have a distinct physiological stress profile. Our findings support the use of these characteristics to identify HCWs at risk of the psychological and physiological stress effects of the pandemic.

Résumé :

The dynamic behavior of a multitower cable-stayed bridge with the application of partially longitudinal constraint system using viscous fluid dampers under real earthquake ground motions is presented. The study is based on the dynamic finite element model of the Jiashao Bridge, a six-tower cable-stayed bridge in China. The prime aim of the study is to investigate the effectiveness of viscous fluid dampers on the longitudinal seismic responses of the bridge and put forth a multiobjective optimization design method to determine the optimized parameters of the viscous fluid dampers. The results of the investigations show that the control objective of the multitower cable-stayed bridge with the partially longitudinal constraint system is to yield maximum reductions in the base forces of bridge towers longitudinally restricted with the bridge deck, with slight increases in the base forces of bridge towers longitudinally unrestricted with the bridge deck. To this end, a multiobjective optimization design method that uses a nondominating sort genetic algorithm II (NSGA-II) is used to optimize parameters of the viscous fluid dampers. The effectiveness of the proposed optimization design method is demonstrated for the multitower cable-stayed bridge with the partially longitudinal constraint system, which reveals that a design engineer can choose a set of proper parameters of the viscous fluid dampers from Pareto optimal fronts that can satisfy the desired performance requirements.

Résumé :

Vehicle load may not only cause vertical deformation and vibration of suspension bridge but also lead to longitudinal deformation and vibration. And the longitudinal behavior is closely related to the durability of the girder end devices and the bending fatigue failure of suspenders. In this study, the longitudinal deformation behavior and longitudinal vibration of suspension bridge under vehicles, as well as the related influencing factors, are investigated. The underlying mechanism of girder longitudinal movement under the moving vehicles is revealed. Based on the simplified vehicle model of vertical concentrated force, the characteristics of main cable deformation and girder longitudinal displacement under vertical loads are analyzed first. Then, the longitudinal motion equation of the girder under vertical moving loads is derived. Finally, a single long-span suspension bridge is employed in the case study, and the girder longitudinal response and influencing factors are investigated based on both numerical simulation and field monitoring. Results indicate that the asymmetric vertical load leads to cable longitudinal deflection owing to the geometrically nonlinear characteristic of the main cable, leading to longitudinal movement of the girder. The results of field monitoring and numerical simulation indicate that the girder moves quasi-statically and reciprocates longitudinally with centimeter amplitude under normal operational loads.

Résumé :

This study was conducted to evaluate the effects of longitudinal baffles on particles settling performance within a full-scale sedimentation basin with a flow rate of 1,000 m3/hr. Comparative experiments on turbidity removal efficiency and sludge deposit distribution were performed in longitudinally baffled and non-baffled sedimentation basins. The turbidity removal rate in the baffled sedimentation basin was observed to be higher than that in the non-baffled basin. In addition, the depth of the sludge deposit in the baffled sedimentation basin was approximately 20% less than that in the non-baffled sedimentation basin, and the sludge concentration was 10% higher. To explain these results and to further investigate the effects of longitudinal baffles, the authors performed computational fluid dynamics (CFD) simulation for both basin types. The results of this CFD simulation indicated that the flow, particularly near the outlet orifice, was more stable in the longitudinally baffled sedimentation basin. Moreover, it could be concluded that the longitudinal baffle enables a fully developed flow and is thus more effective for sedimentation.

Résumé :

AbstractIn this study, we investigated dual-language decline in non-balanced bilinguals with probable Alzheimer’s disease (AD) both longitudinally and cross-sectionally. We examined patients’ naming accuracy on the Boston Naming Test (BNT: Kaplan et al., 1983) over three testing sessions (longitudinal analysis) and compared their performance to that of matched controls (cross-sectional analysis). We found different longitudinal and cross-sectional patterns of decline: Longitudinally, the non-dominant language seemed to decline more steeply than the dominant language, but, cross-sectionally, differences between patients and controls were larger for the dominant than for the non-dominant language, especially at the initial testing session. This differential pattern of results for cross-sectional versus longitudinal decline was supported by correlations between decline measures and BNT item characteristics. Further studies will be needed to better characterize the nature of linguistic decline in bilinguals with AD; however, these results suggest that representational robustness of individual lexical representations, rather than language membership, might determine the time course of decline for naming in bilinguals with AD.

Résumé :

ObjectiveNeuropathological studies in amyotrophic lateral sclerosis (ALS) have shown a dissemination in a regional sequence in four anatomically defined patterns. The aim of this retrospective study was to see whether longitudinal diffusion tensor imaging (DTI) data support the pathological findings.MethodsThe application of DTI analysis to fibre structures that are prone to be involved at each neuropathological pattern of ALS was performed in a monocentre sample of 67 patients with ALS and 31 controls that obtained at least one follow-up scan after a median of 6 months.ResultsAt the group level, longitudinal ALS data showed significant differences for the stage-related tract systems. At the individual level, 27% of the longitudinally scanned patients with ALS showed an increase in ALS stage, while the remaining were stable or were at the highest ALS stage. Longitudinal fractional anisotropy changes in the respective tract systems correlated significantly with the slope of the revised ALS functional rating scale.InterpretationThe DTI-based protocol was able to image the disease patterns of ALS in vivo cross-sectionally and longitudinally, in support of DTI as a technical marker to image ALS stages.

Résumé :

Shear wave propagation is employed in medical ultrasound imaging, because it reveals variation in the viscoelastic properties of tissue. Frequencies below 1 kHz are required for imaging with shear waves in soft tissue due to their high attenuation and low propagation speeds, compared to compressional waves with frequencies above 1 MHz used for ultrasound imaging. Shear waves exhibiting particle motion in the direction of propagation, referred to as longitudinally polarized shear waves, can be generated by applying longitudinal motion of a circular disk to the surface of a soft elastic medium. This approach is used in practice because it permits imaging of the longitudinal shear wave with a conventional ultrasound transducer that is coaxial with the source of the shear wave. Presented here are the theoretical framework and numerical simulations that illustrate effects of focusing on longitudinally polarized shear waves. Longitudinal, transverse, radial, and torsional source polarizations are considered. The present investigation was motivated initially by an experimental study in optics due to Dorn et al. [Phys. Rev. Lett. 91, 233901 (2003)]. Our predictions for shear wave beams support their measurements of light beams revealing that the longitudinal electric field component produces a smaller focal spot than the transverse field component.

Résumé :

Abstract OBJECTIVE: The filum terminale (FT) is a fibrovascular band involved in the pathophysiology of tethered cord syndrome (TCS). Its morphological and ultrastructural properties remain largely unknown even though they are thought to play a role in the generation of TCS in adult patients with normal level conus medullaris. MATERIALS AND METHODS: Twenty fresh adult human cadavers had their fila measured and removed. Transversal and longitudinal sections of the proximal, middle, and distal thirds of FT were submitted to light microscopy analysis with four different techniques. Five fila were selected for longitudinal and transversal scanning electron microscopy analysis. RESULTS: The bulk of the FT is composed of 5- to 20-μm thick longitudinal bundles of Type 1 collagen separated by 3- to 10-μm intervals, although capillaries and other elements may be present. A delicate (0.05–1.5 μm) meshwork of predominantly Type 3 collagen transversal fibers connects these bundles. Abundant longitudinally oriented elastic and elaunin fibers are found inside collagen bundles. A complex tridimensional structure is evidenced on electron microscopy. CONCLUSION: The longitudinal arrangement of collagen bundles and the impressive amount of elastic and elaunin fibers should elicit considerable elastic properties to the FT. An altered elasticity mechanism has been proposed for TCS; further studies are needed with TCS patients to define whether the collagen structure, Type 1/Type 3 proportion, or elastic fiber content are altered, which could lead to new histopathological definitions of TCS, helping neurosurgeons in the difficult management of TCS patients with normal level conus medullaris.

Résumé :

Abstract The Long Life Family Study (LLFS) has longitudinally measured key aging phenotypes on 4,953 participants (539 pedigrees) in the USA and Denmark selected for exceptional familial longevity. On average, both generations of the LLFS sample are healthier than average for their age/sex, for many phenotypes. However, the pedigrees are heterogeneous, with different families showing familial clustering of protection for different phenotypes. Linkage analyses identified extremely strong genetic linkage peaks for many cross-sectional as well as longitudinal trajectory rates of change phenotypes. These peaks are NOT explained by GWAS SNPs (either measured or imputed). Pedigree specific HLODs and preliminary deep sequencing suggests that these peaks are driven by rare, protective variants running in selected pedigrees. Whole Genome Sequencing, a third longitudinal visit, and extensive OMICs (transcriptomics, epigenomics, metabolomics and proteomics) will help us resolve the mechanisms behind these protective genetically linked variants, and could illuminate new biology and enable new therapeutics.

Résumé :

The Panel Study of Income Dynamics (PSID) has, over its 50-year history, proven to be a useful source of data for research on virtually all the major topics in the area of social gerontology. This usefulness reflects three of the leading features of the PSID: its longitudinality; its content; and its tracking rules, which permit users to develop family-based and generationally linked measures. This article summarizes key areas of survey content, including both routinely collected data and several one-time or occasional supplements to the routine items. The article also illustrates how these data elements have been used, providing examples of published papers in several areas of social gerontology. Finally, the article points out some methodological issues associated with the PSID design; these methodological issues arise, in varying degrees, in longitudinal studies other than the PSID, and should be acknowledged by both the producers and consumers of longitudinal-data research.

Résumé :

ABSTRACTBackground:Epidemiological studies have reported that higher education (HE) is associated with a reduced risk of incident Alzheimer's disease (AD). However, after the clinical onset of AD, patients with HE levels show more rapid cognitive decline than patients with lower education (LE) levels. Although education level and cognition have been linked, there have been few longitudinal studies investigating the relationship between education level and cortical decline in patients with AD. The aim of this study was to compare the topography of cortical atrophy longitudinally between AD patients with HE (HE-AD) and AD patients with LE (LE-AD).Methods:We prospectively recruited 36 patients with early-stage AD and 14 normal controls. The patients were classified into two groups according to educational level, 23 HE-AD (>9 years) and 13 LE-AD (≤9 years).Results:As AD progressed over the 5-year longitudinal follow-ups, the HE-AD showed a significant group-by-time interaction in the right dorsolateral frontal and precuneus, and the left parahippocampal regions compared to the LE-AD.Conclusion:Our study reveals that the preliminary longitudinal effect of HE accelerates cortical atrophy in AD patients over time, which underlines the importance of education level for predicting prognosis.
