Successful African American students in two-way immersion programs: parent and student perceptions

The purpose of this study was to examine perceptions of possible factors that lead to academic success for African American children who participated in two-way immersion programs. In order to examine the perceptions, the following areas were explored: 1.) The evolution of the academic achievement gap that exists between African American and Anglo children and the reasons theorists gave as to why the gap exists, as well as the importance of this connection to two-way immersion program participation 2.) The evolution of the modern two-way immersion language program via its development through bilingual education, and 3.) The development of Canadian twoway immersion language programs, and how political, economic, and cultural factors have impacted their successful implementation. The research method consisted of purposeful sampling of six African-American children in fourth and fifth grade who are participants in an elementary two-way immersion language program and their primary caregivers. The interviews were audio taped with notes taken for clarity. The data revealed that the primary caregivers perceived the participation of their children in a two-way language immersion program to be an educational move which would enhance the lives of their children economically, educationally and socially. The primary caregivers maintained involvement in the education of their children through facilitating homework completion in Spanish, communicating with teachers on a regular basis, participating in PTO, and facilitating structured and unstructured extra curricular activities with family and friends. The children perceived positive teacher interaction to play an important role in their academic success. They had positive experiences speaking Spanish with friends, family, and persons that they did not know. The primary caregivers perceived that the school and the district did not provide enough additional support to facilitate Spanish language acquisition for their children. This would indicate that more support from the school and the district is needed for future groups of African-American children in two-way immersion language programs

Quantum state transfer in a q-deformed chain

We investigate the quantum state transfer in a chain of particles satisfying q-deformed oscillators algebra. This general algebraic setting includes the spin chain and the bosonic chain as limiting cases. We study conditions for perfect state transfer depending on the number of sites and excitations on the chain. They are formulated by means of irreducible representations of a quantum algebra realized through Jordan-Schwinger maps. Playing with deformation parameters, we can study the effects of nonlinear perturbations or interpolate between the spin and bosonic chain.Comment: 13 pages, 4 figure

Responding to industry needs for proactive engagement in work integrated learning (WIL): Partnerships for the future

With increasing global competitiveness and the need for innovative and entrepreneurial employees, industry are seeking graduates with the skills to meet the demands of an uncertain workplace. Work Integrated Learning (WIL), where skill development is scaffolded across the curriculum, is essential to ensure students are work-ready and prepared for the transition from study to work. Robust partnerships with industry are fundamental to enacting a WIL curriculum as they provide the real world perspective. While industry partners are keen to engage with universities to support authentic learning for students, recent reports highlight the need for industry-focussed resources to facilitate optimal outcomes. This research, funded by The Office of Learning and Teaching (OLT), aimed to determine the topics, format and mode of resources that industry perceived as most useful. The project used a mixed methods approach to ascertain strategies and resources required by industry to support their engagement in WIL. A combination of roundtable discussions, workshops and a survey were deployed to gather data and validate research findings. Outcomes confirmed the topics mode and type of resources industry are seeking. The research will inform national initiatives aimed to enhance the capacity of industry partners to participate in WIL activities

Anthocyanins do not influence long-chain n-3 fatty acid status:Studies in cells, rodents and humans

Increased tissue status of the long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFA), eicosapentaenoic (EPA) and docosahexaenoic acid (DHA) is associated with cardiovascular and cognitive benefits. Limited epidemiological and animal data suggest that flavonoids, and specifically anthocyanins, may increase EPA and DHA levels, potentially by increasing their synthesis from the shorter-chain n-3 PUFA, α-linolenic acid. Using complimentary cell, rodent and human studies we investigated the impact of anthocyanins and anthocyanin-rich foods/extracts on plasma and tissue EPA and DHA levels and on the expression of fatty acid desaturase 2 (FADS2), which represents the rate limiting enzymes in EPA and DHA synthesis. In experiment 1, rats were fed a standard diet containing either palm oil or rapeseed oil supplemented with pure anthocyanins for 8 weeks. Retrospective fatty acid analysis was conducted on plasma samples collected from a human randomized controlled trial where participants consumed an elderberry extract for 12 weeks (experiment 2). HepG2 cells were cultured with α-linolenic acid with or without select anthocyanins and their in vivo metabolites for 24 h and 48 h (experiment 3). The fatty acid composition of the cell membranes, plasma and liver tissues were analyzed by gas chromatography. Anthocyanins and anthocyanin-rich food intake had no significant impact on EPA or DHA status or FADS2 gene expression in any model system. These data indicate little impact of dietary anthocyanins on n-3 PUFA distribution and suggest that the increasingly recognized benefits of anthocyanins are unlikely to be the result of a beneficial impact on tissue fatty acid status

Rare Germline DICER1 Variants in Pediatric Patients With Cushing's Disease: What Is Their Role?

Context: The DICER1 syndrome is a multiple neoplasia disorder caused by germline mutations in the DICER1 gene. In DICER1 patients, aggressive congenital pituitary tumors lead to neonatal Cushing's disease (CD). The role of DICER1 in other corticotropinomas, however, remains unknown. Objective: To perform a comprehensive screening for DICER1 variants in a large cohort of CD patients, and to analyze their possible contribution to the phenotype. Design, setting, patients, and interventions: We included 192CD cases: ten young-onset (age <30 years at diagnosis) patients were studied using a next generation sequencing panel, and 182 patients (170 pediatric and 12 adults) were screened via whole-exome sequencing. In seven cases, tumor samples were analyzed by Sanger sequencing. Results: Rare germline DICER1 variants were found in seven pediatric patients with no other known disease-associated germline defects or somatic DICER1 second hits. By immunohistochemistry, DICER1 showed nuclear localization in 5/6 patients. Variant transmission from one of the parents was confirmed in 5/7 cases. One patient had a multinodular goiter; another had a family history of melanoma; no other patients had a history of neoplasms. Conclusions: Our findings suggest that DICER1 gene variants may contribute to the pathogenesis of non-syndromic corticotropinomas. Clarifying whether DICER1 loss-of-function is disease-causative or a mere disease-modifier in this setting, requires further studies.This work was supported by the Intramural Research Programs of Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) and National Institute for Neurological Diseases and Stroke, National Institutes of Health, a grant from the Basque Department of Education (IT795-13), a grant from the Basque Department of Health (GV2018111082), the Merck Serono Research award from Fundacion Salud 2000 (15-EP-004) and the Jose Igea 2018 grant, sponsored by Pfizer, from Fundacion Sociedad Espanola de Endocrinologia Pediatrica (SEEP)
