or : Dual Language Learners' Grammatical Variability in Narrative Retells.

Purpose: This longitudinal study investigated the trajectory of Spanish article accuracy in Spanish-English dual language learners (DLLs) from preschool to first grade, addressing the need for longitudinal data on the variability of Spanish grammatical skills in DLLs in English immersion classrooms.

Method: Language sample analysis was conducted on 336 Spanish and English narrative retells elicited from 31 Spanish-English DLLs (range: 45-85 months). Growth curve models captured within- and between-individual change in article accuracy from the beginning of preschool to the end of first grade.

Toward a Multi-Modal Brain-Body Assessment in Parkinson's Disease: A Systematic Review in fNIRS.

Parkinson's disease (PD) causes impairments in cortical structures leading to motor and cognitive symptoms. While common disease management and treatment strategies mainly depend on the subjective assessment of clinical scales and patients' diaries, research in recent years has focused on advances in automatic and objective tools to help with diagnosing PD and determining its severity. Due to the link between brain structure deficits and physical symptoms in PD, objective brain activity and body motion assessment of patients have been studied in the literature.

A cross-sectional investigation of disfluencies in typically developing Spanish-English bilingual children.

Purpose: This study examined the language skills and the type and frequency of disfluencies in the spoken narrative production of typically developing Spanish-English bilingual children.

Method: A cross-sectional sample of 106 bilingual children (50 boys; 56 girls) enrolled in kindergarten through Grade 4, produced a total of 212 narrative retell language samples in English and Spanish. A specialized fluency coding system was implemented to index the percentage of total (%TD) and stuttering-like disfluencies (%SLD) in each language.

Purpose: This research aimed to evaluate evidence of Pathways parent-mediated early autism intervention as a culturally and linguistically sensitive intervention (CLSI) for Hispanic families with autistic children.

Methods: We used Bernal et al.'s ecologically valid (EV) framework to evaluate current practice and Hispanic parents' perceptions of Pathways 1 ½ years after completing the intervention.

Post-stroke rehabilitation of the ankle joint with a low cost monoarticular ankle robotic exoskeleton: Preliminary results.

Stroke generates a high rate of disability and, in particular, ankle spasticity is a sequelae that interferes with the execution of daily activities. Robotic devices have been proposed to offer rehabilitation treatments to recover control of ankle muscles and hence to improve gait function. The aim of this study is to investigate the effects of passive stretching, combined with active and resisted movement, accompanied by visual feedback, by means of playful interactive software using a low-cost monoarticular robot (MEXO) in patients with stroke sequelae and spastic ankle.

Measuring Cognitive Workload Using Multimodal Sensors.

This study aims to identify a set of indicators to estimate cognitive workload using a multimodal sensing approach and machine learning. A set of three cognitive tests were conducted to induce cognitive workload in twelve participants at two levels of task difficulty (Easy and Hard). Four sensors were used to measure the participants' physiological change, including, Electrocardiogram (ECG), electrodermal activity (EDA), respiration (RESP), and blood oxygen saturation (SpO2).

Dual Language Profiles in Spanish-Speaking English Learners.

Purpose: The purpose of this study was to identify and describe latent dual language profiles in a large sample of school-age Spanish-English bilingual children designated as English learners (ELs) by their school district.

Method: Data for this study include 847 Spanish-speaking ELs from kindergarten to third grade. Spanish and English narrative retell language samples were collected from all participants.

Chest and pelvis coordination during functional reach test: A possible indication of balance deficiency in older adults.

Falls in older adults represent the most common cause of injuries and a major cause of mortality in this vulnerable population. The morbidity and mortality rate of falls among older people makes balance analysis in older adults very important. Therefore, this study aims to explore different metrics that can potentially be used to identify early indications of balance loss and fall risk.

Self-Regulation Development Among Young Spanish-English Dual Language Learners.

Despite strong evidence self-regulation skills are critical for school readiness, there remains a dearth of longitudinal studies that describe developmental trajectories of self-regulation, particularly among low-resource and underrepresented populations such as Spanish-English dual-language learners (DLLs). The present study examined individual differences in trajectories of self-regulation among 459 Spanish-English DLLs who were Hispanic from four different samples and three geographic locations in the U.S.

A Longitudinal Study of Spanish Language Growth and Loss in Young Spanish-English Bilingual Children.

This longitudinal study examined trajectories of Spanish language growth and loss in 34 Spanish-English bilingual children attending an English immersion school. Narrative retell language samples were collected in Spanish across 3 years using wordless, picture storybooks. Digital audio recordings were transcribed, coded, and analyzed for mean length of utterance in words, proportion of grammatical utterances, and moving-average type-token ratio.

Osteosarcoma of the Trapezium.

Osteogenic sarcoma is a malignant tumor that rarely affects the hand. When it does, it most often involves the phalanges or metacarpal heads. We present the case of a 51-year-old woman with a low-grade osteosarcoma affecting the trapezium bone of her left hand.

Beyond Scores: Using Converging Evidence to Determine Speech and Language Services Eligibility for Dual Language Learners.

Purpose Speech-language pathologists have both a professional and ethical responsibility to provide culturally competent services to dual language learners (DLLs). In this tutorial, we recommend that clinicians use a comprehensive assessment of converging evidence to make diagnostic decisions in DLLs in accordance with the American Speech-Language-Hearing Association's Code of Ethics. The content of this tutorial is most appropriate for Spanish-English DLLs between the ages of 4 and 8 years.

Speaking and Reading in Two Languages: On the Identification of Reading and Language Disabilities in Spanish-Speaking English Learners.

Articles in this issue examine (1) the primary sources of variability in reading and language achievement among Spanish-speaking English learners (ELs) in the United States, (2) the extent to which poor performance at the end of grade 2 is identifiable in developmental trajectories beginning in kindergarten, (3) the relations among core reading constructs of phonological awareness and decoding in both English and Spanish and the factors that affect their relationship, (4) the performance of different approaches to identification and the factors that influence how well they work, as well as (5) the growing literature focused on intervention for reading problems in this population. This article examines the literature on language minority students and disability identification and analyzes a large-scale longitudinal dataset (>4,000 ELs; >15,000 observations) to systematically characterize and describe the oral language and reading development of Spanish-speaking children designated as ELs from kindergarten to second grade, considering a range of factors that may potentially contribute to that characterization and its relation to academic performance. This systematic characterization should facilitate the development of an empirical basis for a theoretically grounded framework of typical development in ELs in order to more precisely identify those children with language and learning disabilities.

Moving Forward by Looking Back: Understanding Why Some Spanish-Speaking English Learners Fall Behind.

This study investigated early indicators of Spanish-speaking English learners (ELs) at risk for reading difficulties at the end of Grade 2 by examining their early bilingual oral language development, taking into account language of academic instruction. Standardized measures of reading and narrative samples were collected in English and Spanish from kindergarten to Grade 2 from 1,243 ELs primarily instructed in English or Spanish. Conditional growth curve models yielded four primary findings of reading and oral language development.

IQ-Achievement Discrepancy for Identification of Disabilities in Spanish-speaking English Learners.

This article examines the validity of IQ-achievement discrepancy and low achievement as criteria for the identification of disabilities in Spanish-speaking English-language learners (ELs) and the factors that moderate the validity of these approaches as bases for identification. While there has been a long history of examining the validity of different approaches to disability identification in monolinguals, there are no systematic approaches taken for ELs. Data from Grades 1 and 2 of a large longitudinal data set consisting of young Spanish-speaking students attending schools in the United States were used to empirically examine criteria for disability identification among language minority children-one of the first large-scale attempts.

[Eating behavior and its association with nutritional status and physical activity in a general Chilean population].

Introduction: obesity has become a chronic disease whose etiology can be based on an imbalance between the contribution and energy expenditure of the individual, where the behavior against food consumption and physical activity play an important role as determinants in this energy balance.

Methods: in the present study, behavior in relation to food consumption and physical activity and its association with nutritional status in a general Chilean population was analyzed. It was a cross-sectional study in 629 people, belonging to the university community of the Andres Bello University.

The waggle dance is one of the most popular examples of animal communication. Forager bees direct their nestmates to profitable resources via a complex motor display. Essentially, the dance encodes the polar coordinates to the resource in the field.

Tense Marking in the English Narrative Retells of Dual Language Preschoolers.

Purpose: This longitudinal study investigated the emergence of English tense marking in young (Spanish-English) dual language learners (DLLs) over 4 consecutive academic semesters, addressing the need for longitudinal data on typical acquisition trajectories of English in DLL preschoolers.

Method: Language sample analysis was conducted on 139 English narrative retells elicited from 39 preschool-age (Spanish-English) DLLs (range = 39-65 months). Growth curve models captured within- and between-individual change in tense-marking accuracy over time.

The GalNAc-T Activation Pathway (GALA) is not a general mechanism for regulating mucin-type O-glycosylation.

Mucin-type O-glycosylation is initiated by the UDP-GalNAc polypeptide:N-acetylgalactosaminyltransferase (GalNAc-T) family of enzymes. Their activity results in the GalNAc α1-O-Thr/Ser structure, termed the Tn antigen, which is further decorated with additional sugars. In neoplastic cells, the Tn antigen is often overexpressed.

Interlocutor differential effects on the expressive language skills of Spanish-speaking English learners.

Purpose: The primary objective of this study was to investigate the relationship between language use with different interlocutors, maternal education level and the expressive language skills of US English learners (ELs) in Spanish and English.

Method: Two hundred and twenty-four Spanish-speaking ELs in kindergarten provided narrative language samples in Spanish and English. Parents completed a questionnaire of maternal education level and language use with parents, older siblings and peers.

Axial superresolution via multiangle TIRF microscopy with sequential imaging and photobleaching.

We report superresolution optical sectioning using a multiangle total internal reflection fluorescence (TIRF) microscope. TIRF images were constructed from several layers within a normal TIRF excitation zone by sequentially imaging and photobleaching the fluorescent molecules. The depth of the evanescent wave at different layers was altered by tuning the excitation light incident angle.
