Purpose: Emerging literature suggests caregiver self-efficacy is an important factor related to caregivers' shared reading practices with their children. Reduced shared reading has been documented among families of caregiver(s) with language-based learning disabilities (LBLD). Yet, it remains unclear whether caregivers' history of language and reading difficulties is associated with caregiver self-efficacy. The purpose of this study was to examine whether self-efficacy in language- and reading-related caregiver activities related to caregiver history of language and reading difficulties and shared reading practices. Method: One hundred seventy-six caregivers of children aged 18-60 months completed a custom self-efficacy in language- and reading-related caregiver activities questionnaire, as well as demographic, history of language and reading difficulties (used both as a continuous measure and to dichotomize caregivers with and without LBLD history), and shared reading measures in a one-time survey. Results: Caregivers with a history of LBLD reported an overall lower self-efficacy and a reduced amount of time reading with their children per week than caregivers without LBLD history. Examining caregiver history of language and reading difficulties continuously across the whole group, self-efficacy mediated the relationship between caregiver difficulties and shared reading practices, even when caregiver education was incorporated as an additional mediator in models. Conclusions: Findings indicate that self-efficacy and caregiver education mediate the relationship between caregiver history of language and reading difficulties and shared reading practices. Consideration of self-efficacy by clinicians and educators is warranted when promoting shared reading practices to caregivers of young children. There is a need for future research to examine relationships between self-efficacy and shared reading among caregivers with LBLD of culturally and linguistically diverse backgrounds.

Musical abilities, both in the pitch and temporal dimension, have been shown to be positively associated with phonological awareness and reading abilities in both children and adults. There is increasing evidence that the relationship between music and language relies primarily on the temporal dimension, including both meter and rhythm. It remains unclear to what extent skill level in these temporal aspects of music may uniquely contribute to the prediction of reading outcomes. A longitudinal design was used to test a group-administered musical sequence transcription task (MSTT). This task was designed to preferentially engage sequence processing skills while controlling for fine-grained pitch discrimination and rhythm in terms of temporal grouping. Forty-five children, native speakers of Portuguese (M[subscript age] = 7.4 years), completed the MSTT and a cognitive-linguistic protocol that included visual and auditory working memory tasks, as well as phonological awareness and reading tasks in second grade. Participants then completed reading assessments in third and fifth grades. Longitudinal regression models showed that MSTT and phonological awareness had comparable power to predict reading. The MSTT showed an overall classification accuracy for identifying low-achievement readers in Grades 2, 3, and 5 that was analogous to a comprehensive model including core predictors of reading disability. In addition, MSTT was the variable with the highest loading and the most discriminatory indicator of a phonological factor. These findings carry implications for the role of temporal sequence processing in contributing to the relationship between music and language and the potential use of MSTT as a language-independent, time- and cost-effective tool for the early identification of children at risk of reading disability.

Purpose: This study examined how speakers adapt to fundamental frequency (f[subscript o]) errors that affect the use of prosody to convey linguistic meaning, whether f[subscript o] adaptation in that context relates to adaptation in linguistically neutral sustained vowels, and whether cue trading is reflected in responses in the prosodic cues of f[subscript o] and amplitude. Method: Twenty-four speakers said vowels and sentences while f[subscript o] was digitally altered to induce predictable errors. Shifts in f[subscript o] (±200 cents) were applied to the entire sustained vowel and one word (emphasized or unemphasized) in sentences. Two prosodic cues--f[subscript o] and amplitude--were extracted. The effects of f[subscript o] shifts, shift direction, and emphasis on f[subscript o] response magnitude were evaluated with repeated-measures analyses of variance. Relationships between adaptive f[subscript o] responses in sentences and vowels and between adaptive f[subscript o] and amplitude responses were evaluated with Spearman correlations. Results: Speakers adapted to f[subscript o] errors in both linguistically meaningful sentences and linguistically neutral vowels. Adaptive f[subscript o] responses of unemphasized words were smaller than those of emphasized words when f[subscript o] was shifted upward. There was no relationship between adaptive f[subscript o] responses in vowels and emphasized words, but adaptive f[subscript o] and amplitude responses were strongly, positively correlated. Conclusions: Sensorimotor adaptation occurs in response to f[subscript o] errors regardless of how disruptive the error is to linguistic meaning. Adaptation to f[subscript o] errors during sustained vowels may not involve the exact same mechanisms as sensorimotor adaptation as it occurs in meaningful speech. The relationship between adaptive responses in f[subscript o] and amplitude supports an integrated model of prosody.

Objectives The COVID-19 pandemic has had a disproportionate impact on the health of Indigenous Peoples in Canada, Australia, New Zealand and the USA, as reflected in the growing literature. However, Indigenous Peoples are often homogenised, with key differences often overlooked, failing to capture the complexity of issues and may lead to suboptimal public health policy-making. The objective of this review was to assess the extent to which the heterogeneity of the Indigenous Peoples in Canada, Australia, New Zealand and the USA has been reflected in COVID-19 research.Design This study took the form of a scoping review.Data sources Medline, Embase, CINAHL and Web of Science were searched for studies investigating COVID-19 pandemic outcomes among Indigenous Peoples in Canada, Australia, New Zealand and the USA. The search dates included January 2019 to January 2024.Eligibility criteria All citations yielded by this search were subjected to title and abstract screening, full-text review and data extraction. We included original, peer-reviewed research investigating COVID-19-related outcomes among Indigenous Peoples in Canada, Australia, New Zealand or the USA.Data extraction and synthesis Data extraction was conducted as an iterative process, reaching consensus between two of the study authors. All included studies were analysed through a combination of quantitative descriptive summary and qualitative thematic analysis.Results Of the 9795 citations found by the initial search, 428 citations were deemed eligible for inclusion. Of these citations: 72.9% compared Indigenous participants to non-Indigenous participants; 10.0% aggregated Indigenous and non-white participants; and 17.1% provided findings for Indigenous participants exclusively.Conclusions By overlooking the heterogeneity that exists among Indigenous Peoples in Canada, Australia, New Zealand and the USA, researchers and policy-makers run the risk of masking inequities and the unique needs of groups of Indigenous Peoples. This may lead to inefficient policy recommendations and unintentionally perpetuate health disparities during public health crises.

Background/purpose: In response to the opioid use challenges exacerbated from the COVID-19 pandemic, Fort Albany First Nation (FAFN), a remote Cree First Nation community situated in subarctic Ontario, Canada, implemented a buprenorphine-naloxone program. The newly initiated program was collaboratively developed by First Nations' nurses and community leaders, driven by the community's strengths, resilience, and forward-thinking approach. Using the First Nations Information Governance Centre strengths-based model, this article examines discussions with four community leaders to identify key strengths and challenges that emerged during the implementation of this program. Methods: This qualitative study amplify the positive aspects and community strengths through the power of oral narratives. We conducted 20 semi-structured face-to-face interviews with community members who helped lead FAFN's COVID-19 pandemic response. Utilizing the Medicine Wheel framework, this work introduces a holistic model for the buprenorphine-naloxone program that addresses the cognitive, physical, spiritual, and emotional dimensions of well-being. Results: Recommendations to support this initiative included the need for culturally competent staff, customized education programs, and the expanding of the program. Additionally, there is a pressing need for increased funding to support these initiatives effectively and sustainably. The development of this program, despite challenges, underscores the vital role of community leadership and cultural sensitivity to address the opioid crisis in a positive and culturally safe manner. Conclusion: The study highlights the successes of the buprenorphine-naloxone program, which was developed in response to the needs arising from the pandemic, specifically addressing community members suffering from opioid addiction. The timely funding for this program came as the urgent needs of community members became apparent due to pandemic lockdowns and isolation. Holistic care, including mental health services and fostering community relations, is important. By centering conversations on community strengths and advocating for culturally sensitive mental health strategies that nurture well-being, resilience, and empowerment, these findings can be adapted and expanded to support other Indigenous communities contending with opioid addiction.

Musical training has long been viewed as a model for experience-dependent brain plasticity. Reports of musical training-induced brain plasticity are largely based on cross-sectional studies comparing musicians to non-musicians, which cannot address whether musical training itself is sufficient to induce these neurobiological changes or whether pre-existing neuroarchitecture before training predisposes children to succeed in music. Here, in a longitudinal investigation of children from infancy to school age (n = 25), we find brain structure in infancy that predicts subsequent music aptitude skills at school-age. Building on prior evidence implicating white matter organization of the corticospinal tract as a neural predisposition for musical training in adults, here we find that structural organization of the right corticospinal tract "in infancy" is associated with school-age tonal and rhythmic musical aptitude skills. Moreover, within the corpus callosum, an inter-hemispheric white matter pathway traditionally linked with musical training, we find that structural organization of this pathway in infancy is associated with subsequent tonal music aptitude. Our findings suggest predispositions prior to the onset of musical training from as early as infancy may serve as a scaffold upon which ongoing musical experience can build.

BackgroundThe autonomic nervous system (ANS) plays a significant role in atrial fibrillation (AF). Catheter ablation (CA) is a well-established treatment method for AF and significantly affects the ANS, including baroreceptor (BR) function. However, little is known about the changes in BR function caused by radiofrequency (RF) or cryoballoon energy (CB) and its impact on future AF recurrences.PurposeTo assess 1-year efficacy of CA of AF in relation to BR function modification and type of ablation energy used.MethodsThe study group consisted of 78 patients (25 females, mean age 58 ± 9 years) with paroxysmal AF and first CA (39 patients in the RF group and 39 in the CB group). The BR function was assessed non-invasively, using tilt testing before and after CA, and three BR parameters were calculated: event count (BREC) depicting overall BR activity, slope mean depicting BR sensitivity (BRS), and BR effectiveness index (BEI). The efficacy of CA was assessed during 1-year follow-up, which consisted of ambulatory visits and 24-h Holter ECG recordings at 3, 6, and 12 months after CA. The quality of life was assessed by using a dedicated scale [University of Toronto Atrial Fibrillation Severity Scale (AFSS)].ResultsThe two groups did not show differences in terms of clinical or demographic data. One-year follow-up was completed for 35 (89.7%) patients from the CB group and for 34 (87.2%) from the RF group. The rates of efficacy of CB and RF were similar [31/35 (88.6%) vs. 26/34 (76.5%), respectively]. After CA, the BR function decreased in both groups, with a significantly greater decrease in the CB group. The changes in BR parameters were similar in both responders and non-responders after CA in the whole group [BREC 10.0 (2.0–24.0) vs. 12.0 (4.0–21.5), p = 0.939; BRS 5.4 (3.7–6.5) vs. 4.8 (3.6–7.2), p = 0.809; BEI 24.8 (15.9–27.4) vs. 17.5 (8.9–27.5), p = 0.508, respectively]. According to the AFSS, the AF symptoms were significantly reduced in both groups to a similar extent.ConclusionsCA for AF significantly decreased the BR function, especially in patients undergoing CB. There was no correlation between CA-induced changes in BR parameters and ablation outcome.

Introduction: Geese harvesting is a longstanding cultural tradition deeply ingrained among the Omushkego Cree in Fort Albany First Nation, embodying a holistic approach to health that integrates Indigenous knowledge, community wellbeing, and resilience. Despite historical disruptions stemming from colonization and assimilation policies, women have played a pivotal role in preserving and passing down traditional practices. The significance of goose harvesting extends beyond providing a nutrient-rich and cost-effective food source; it serves as a vehicle for cultural preservation and education, particularly fostering language acquisition among children. Nevertheless, concerns persist regarding the potential decline in the transmission of Indigenous knowledge. The interruption of intergenerational knowledge transfer not only poses implications for overall wellbeing but also worsens historical trauma within the community. In response to these challenges, the Niska (goose) harvesting program was developed with an aim to revitalize community harvesting practices, with a specific focus on incorporating the perspectives of women, especially in the preparatory and smoking phases of the geese. Methods: Omushkego Cree women were approached to participate. The study was conducted during the spring of 2018, and employed photovoice and semi-structured interviews that explored the impact of geese preparatory activities on the health and wellbeing of Indigenous women. Results: Major themes from the qualitative data included the importance of knowledge sharing, cultural continuity, healing, and the profound connection to the land. Women emphasized the value of sharing acquired knowledge, passing on traditions, and maintaining a connection to their cultural identity. Cultural continuity, depicted through intergenerational teachings and experiences, emerged as crucial for overall wellbeing. Participants spoke of the healing dynamics derived from engaging in traditional activities, highlighting the positive impact on physical, mental, emotional, and spiritual wellbeing. The land was identified as a central element in this healing process, representing more than just a physical space but an extension of home, contributing to a sense of peace and tranquility. The land became a medium for transmitting cultural teachings, shaping identity, and sustaining a subsistence lifestyle. Conclusion: The study emphasizes the importance of future research including more female youth participants to uncover specific challenges and strengths within this demographic. Overall, the Niska program demonstrates a comprehensive approach that intertwines cultural revitalization, community engagement, and holistic wellbeing, emphasizing the need for interventions that go beyond immediate challenges to create enduring positive impacts on Indigenous communities.

Aims To describe the autonomic function of premature infants born between 28 and 32 weeks of gestation, without medical risk factors, at the age of 3 to 5 years and to assess whether it's possible to predict the appearance of autonomic deficits in these children at this age range.

Purpose: Learning to read is a complex, multifaceted process that relies on several speech and language-related subskills. Individual differences in word reading outcomes are indicated among children with inaccurate speech sound productions, with some of these children developing later reading difficulties. There are inconsistent reports as to whether phonological deficits and/or weaknesses in oral language explain these subsequent reading difficulties. Thus, it remains unclear how variability in speech production accuracy in early childhood may impact reading development. Therefore, the present longitudinal study seeks to clarify the relation between speech sound production accuracy in kindergarten and subsequent reading outcomes with a focus on additional potential mediating factors. Method: Speech accuracy, core preliteracy skills (phonological awareness, rapid naming, and letter-name knowledge), and additional potential mediators (phonological memory and oral language abilities) were characterized at the start of formal reading instruction. Word reading, decoding, reading fluency, and comprehension were assessed at the end of second grade. Mediation analyses were conducted to examine factors that mediate the relation between speech accuracy in kindergarten and subsequent reading outcomes. Results: Initial associations between early speech sound production accuracy and subsequent reading outcomes were indicated; however, mediation effects of preliteracy skills (phonological awareness and letter-name knowledge) were identified for word reading, decoding, and reading fluency outcomes. For reading comprehension, mediation effects of preliteracy and vocabulary skills were observed. Conclusions: The relation between speech sound production accuracy and subsequent word reading, decoding, reading fluency, and comprehension was observed to be mediated by preliteracy skills, specifically phonological awareness and letter-name knowledge. For reading comprehension only, vocabulary knowledge were of additional importance.

Abstract We derive the field-dependent masses in Fermi gauges for arbitrary scalar extensions of the Standard Model. These masses can be used to construct the effective potential for various models of new physics. We release a flexible Mathematica notebook (VefFermi) which performs these calculations and renders large-scale phenomenological studies of various models possible. Motivated by the debate on the importance of gauge dependence, we show that, even in relatively simple models, there exist points where the global minimum is discontinuous in the gauge parameter. Such points require some care in discovering, indicating that a gauge-dependent treatment might still give reasonable results when examining the global features of a model.

Purpose: Beyond hallmark production deficits characterizing childhood apraxia of speech (CAS), largely attributed to disruption(s) in speech motor planning, children with CAS often present with co-occurring speech perception and language difficulties. Thus, careful consideration of the potential for speech perception difficulties to have cascading downstream effects on intervention responsiveness and real-life functioning for some children with CAS is highly important. The purpose of this tutorial was to consider the impact of speech perception abilities in children with CAS, which carries implications for caring for the needs of the whole child. Method: This tutorial summarizes the current literature on speech perception and how it relates to speech production, language, and reading abilities for children with CAS. We include case illustrations that are adapted from real clinical scenarios illustrating how speech perception difficulties may impact some children with CAS and provide recommendations for incorporating speech perception into assessment and intervention practices. Results: Although speech perception difficulties do not seem to be a core deficit of CAS, they are strongly linked to language difficulties, which are highly prevalent among children with CAS. Speech perception and language difficulties are also associated with reading difficulties and risk for lower academic achievement. Conclusions: Children with CAS who have co-occurring language difficulties likely also demonstrate speech perception deficits, which puts them at heightened risk for reading difficulties and struggles with academic achievement. Comprehensive assessment of children with CAS should address speech perception and production, language, and reading abilities, which carries important implications for multifaceted approaches to intervention.

Background: There has been substantial controversy in the neuroethics literature regarding the extent to which deep brain stimulation (DBS) impacts dimensions of personality, mood, and behavior.Objective/Hypothesis: Despite extensive debate in the theoretical literature, there remains a paucity of empirical data available to support or refute claims related to the psychosocial changes following DBS. Methods: A mixed-methods approach was used to examine the perspectives of patients who underwent DBS regarding changes to their personality, authenticity, autonomy, risk-taking, and overall quality of life. Results: Patients (n = 21) who were enrolled in adaptive DBS trials for Parkinson's disease, essential tremor, obsessive-compulsive disorder, Tourette's syndrome, or dystonia participated. Qualitative data revealed that participants, in general, reported positive experiences with alterations in what was described as ‘personality, mood, and behavior changes.’ The majority of participants reported increases in quality of life. No participants reported ‘regretting the decision to undergo DBS.’ Conclusion(s): The findings from this patient sample do not support the narrative that DBS results in substantial adverse changes to dimensions of personality, mood, and behavior. Changes reported as “negative” or “undesired” were few in number, and transient in nature.

Positive relationships between the home literacy environment and children's language and literacy development are well-established. However, existing literature has overlooked the potential contributions of the home music environment. Initial evidence indicates positive relationships between the home music environment and children's emerging language and literacy skills, yet it remains unclear whether and how children's home music and literacy environments may be related. Furthermore, parents' sense of self-efficacy is known to impact the home environment provided for their children. Despite being linked with the home literacy environment, parental self-efficacy has not been directly investigated in relation to the home music environment. In the present study, 124 caregivers of preschoolers completed a one-time online survey about their children's home music environment, home literacy environment, and parental self-efficacy. Partial correlations and hierarchical regressions reveal that children's amount of music exposure is associated with qualitative (not quantitative) aspects of the home literacy environment, specifically parents' use of interactive techniques during shared reading. Moreover, parental self-efficacy is associated with children's amount of exposure to music. Overall, these findings support the need to further examine how the home music environment may meaningfully contribute to an enriching learning environment, especially to support language and literacy development.
