This study explores the literacy development of students who speak Spanish as a heritage language and who participate in mandatory, peer-to-peer tutoring sessions outside of the classroom. We explore students’ academic development as well as their self-positioning as heritage speakers in a bilingual academic setting. Drawing on Systemic Functional Linguistics (SFL), we analyze the written production of seven bilingual students enrolled in a Native Speaker Program at a large, public university. We focus on the development of their academic language through the support of a heritage language tutor and explore the role of the peer tutor as a facilitator in this process. Additionally, we employ Appraisal Theory to analyze interviews in which the same participants explore their bilingual identities and how they position themselves interpersonally as a result of conversations held with a peer mentor, thus demonstrating the benefits of learning Spanish as a heritage language through peer-led learning in academic contexts.

Arterial tortuosity syndrome (ATS) is a rare autosomal recessive disorder caused by mutations in the solute carrier family 2 member 10 (SLC2A10) gene encoding a glucose/ascorbic acid transporter. The clinical features of ATS are mild-to-severe tortuosity of the large and medium arteries throughout the body, accompanied by dysmorphisms and joint laxity. Vascular changes in different parts of the body lead to stenosis and/or aneurysms requiring difficult surgical procedures. Here we present two new patients with ATS from two unrelated families. Patient 1 presented at 10 years of age with headache and typical physical appearance, delicate skeleton, large visible pulsation of the carotid arteries in the neck, and joint laxity. On computed tomography (CT) angiography she had severe tortuosity of the aortal branches and cerebral arteries, but no significant tortuosity of the pulmonary arteries. Two cousins of the girl carried the same homozygous c.254T>C, p.(Leu85Pro) mutation in SLC2A10, however, they additionally had a severe involvement of the pulmonary vessels. Patient 2 was a 9-year-old girl diagnosed with severe tortuosity and stenosis of the pulmonary arteries and progressive myocardiopathy. Her physical appearance was very similar to Patient 1, except that she also had growth retardation. After long-term follow-up by cardiologists, she underwent cardiac surgery abroad, with an unfavorable outcome. Homozygosity for the c.685C>T, p.(Arg229*) mutation in the SLC2A10 gene was detected. Consanguinity was disclosed within both families. Our findings confirm the intrafamilial phenotype variability of ATS. A novel finding is the severe tortuosity of cerebral arteries causing migraine that has not been described before in a child with ATS.

Heritage language speakers constitute a unique cultural and linguistic resource in the United States while also presenting particular challenges for language educators and language programs. This paper examines the potential of systemic functional linguistics (SFL) in a curriculum for Spanish second language learners/heritage speakers, with particular emphasis on the meaning-making of language in the construal of discourse. Following SFL pedagogy, descriptive language teaching refers to ways of treating language in functional terms; productive language teaching involves students in using the resource of their language in powerful ways in light of the demands of particular social contexts. Many heritage speakers have developed their heritage language (Spanish) in the family context but want to be able to use it in the professional areas. SFL with its explicit focus on language allows for the development of advanced literacy in a heritage language in the educational context. Accordingly, the paper discusses explicit instruction of genre/register theory as a way of promoting students' awareness of discourse-semantics and lexicogrammatical features of academic language in courses for heritage speakers. Students' success in developing academic registers in Spanish is evident in their use of lexicogrammatical features (such as grammatical metaphor) that index academic writing.

Introduction: This work aims to provide an updated overview of the eating disorders (EDs) which are a widespread pathology nowadays. Informations related to the clinical-nosographic characteristics, an in-depth analysis about systemic-relational theories and historical evolution are provided. In addition, current informations about epidemiological data, recovery, treatment related implications, new neuroscientific theories and risk factors are shown. Given the complexity of these disorders, the lack of resources and the the increasing demands for treatment, the main object is related to the construction of a questionnaire to manage the waiting lists. Objectives: Building a waiting list management model for EDs, Study and compare advantages and disadvantages of the source allocation ethical models (utilitarianism, prioritarianism, egalitarianism), Analyze EDs leading experts (doctors, dietitians, psychologists, psychiatrists) and EDs patients positioning with respect to priority treatment factors. Promote constructive dialog between EDs experts from different backgrounds and EDs patients. Methods: In order to know the various treatment alternatives available, the different levels and reference structures are illustrated. In addition, it is also suggested different reasoning based on the ethical models of egalitarianism, utilitarianism and prioritarianism in order to build a waiting list management model, which is the maximum goal of this work. This model needs to be supported by a series of validated tools such as the clinical interview and self-administered questionnaires to investigate psychopathological aspects and psychiatric symptoms. Going into more details, a questionnaire is proposed to the EDs leading experts, so that they can provide their own priority factors list and related thoughts in order to build "the most ethical" waiting list. Results: It is expected that both patients and clinicians tend to give priority to patients with greater psychophysical severity, not exclusively on the basis of physical parameters. Further hypothesis related to clinicians lead us believe that they tend to use utilitarian logics, in compliance with the demonstrated efficacy of early intervention. An evaluation that could lead to a disagreement between experts and patients is related to prioritize patients in the initial phase of the disease, which could be supported by clinicians, but not by patients, probably in connection with their personal experiences. In fact, this favoritism could have a negative impact on the care of the most serious cases who risk to be left to themselves. Conclusions: This work aims to encourage a constructive dialogue between experts and patients with EDs in order to build a functional intervention model which should be "the most ethical as possible" in order to save the greatest number of lives in respect of mental suffering.

Neutrinos in astrophysical environments, such as Supernovae (SNe), may interact through pair interactions. These interactions are density and temperature-dependent. Under certain conditions, a neutrino-condensate may form. In this work, we have adapted the separable nonlocal pairing interactions to the SN conditions and studied the temperature and density dependence of the pairing gap as well as the collective response with respect to these variables. We have applied the Bogoliubov transformations and solved the Bardeen, Cooper and Schrieffer (BCS) equations to construct the free quasi-particle sector of the Hamiltonian. The residual two-quasi-particle terms have been treated by applying the Tamm–Dancoff approximation (TDA) and random-phase approximation (RPA), suited to the extended neutrino media. With this, we have constructed neutrino energy distributions both in the superfluid and normal regimes and extracted critical values of the density and temperature. [ABSTRACT FROM AUTHOR]
