The feelings we harbor - the role of collage in arousing powerful emotions in an ESL classroom.

Traditional literacy education in the U.S. relies exclusively on language-based models. This can be particularly challenging for English language learners, who often find themselves bound by the constraints of the English language and limited in their expressions of thought and emotion. Current research on English language teaching, largely targeted towards native English-speaking students, suggests that incorporating various alternate modes of communication and representation improves literacy learning. Studies that address English language learning for non-native speakers are sparse. The purpose of this arts-based, qualitative, descriptive study is to fill this gap in the literature. Using collage making as a communicative mode, I conducted pre- and post-project, semi-structured, ethnographic interviews with students and teachers. I used control-value theory to explore student artwork, and to analyze student emotion about collage making. Study results showed that collage was successful as a communicative mode in an English as a second language (ESL) classroom. Through collage, English language learners were able to express creativity, emotion, and language and to share stories. The collages were instrumental in the students’ achievements, class participation, and feelings of self-satisfaction

PILOT: design and capabilities

The proposed design for PILOT is a general-purpose, wide-field 1 degree 2.4m, f/10 Ritchey-Chretien telescope, with fast tip-tilt guiding, for use 0.5-25 microns. The design allows both wide-field and diffraction-limited use at these wavelengths. The expected overall image quality, including median seeing, is 0.28-0.3" FWHM from 0.8-2.4 microns. Point source sensitivities are estimated.Comment: 4 pages, Proceedings of 2nd ARENA conference 'The Astrophysical Science Cases at Dome C', Potsdam, 17-21 September 200

If desired, a fluid cooling system and an active gasket may also be provided between the door assembly and the enclosed structure. The fluid cooling system preferably includes a second thermoelectric device to maintain the temperature of fluid flowing through the active gasket at a selected value. The drawers associated with the refrigerator may be used for gathering, processing, shipping and storing food or other perishable items

Formation of a quasicrystalline Pb monolayer on the ten-fold surface of the decagonal Al-Ni-Co quasicrystal

Lead has been deposited on the ten-fold surface of decagonal Al72Ni11Co17 to form an epitaxial quasicrystalline single-element monolayer. The overlayer grows through nucleation of nanometer-sized irregular islands and the coverage saturates at 1 ML. The overlayer is well-ordered quasiperiodically as evidenced by LEED and Fourier transforms of STM images. Annealing the film to 600 K improves the structural quality, but causes the evaporation of some material such that the film develops pores. Electronic structure measurements using X-ray photoemission spectroscopy indicate that the chemical interaction of the Pb atoms with the substrate is weak.Comment: 12 pages, 5 figure

Functional characterization and discovery of modulators of SbMATE, the agronomically important aluminium tolerance transporter from Sorghum bicolor.

About 50% of the world's arable land is strongly acidic (pH ≤ 5). The low pH solubilizes root-toxic ionic aluminium (Al3+) species from clay minerals, driving the evolution of counteractive adaptations in cultivated crops. The food crop Sorghum bicolor upregulates the membrane-embedded transporter protein SbMATE in its roots. SbMATE mediates efflux of the anionic form of the organic acid, citrate, into the soil rhizosphere, chelating Al3+ ions and thereby imparting Al-resistance based on excluding Al+3 from the growing root tip. Here, we use electrophysiological, radiolabeled, and fluorescence-based transport assays in two heterologous expression systems to establish a broad substrate recognition profile of SbMATE, showing the proton and/or sodium-driven transport of 14C-citrate anion, as well as the organic monovalent cation, ethidium, but not its divalent analog, propidium. We further complement our transport assays by measuring substrate binding to detergent-purified SbMATE protein. Finally, we use the purified membrane protein as an antigen to discover native conformation-binding and transport function-altering nanobodies using an animal-free, mRNA/cDNA display technology. Our results demonstrate the utility of using Pichia pastoris as an efficient eukaryotic host to express large quantities of functional plant transporter proteins. The nanobody discovery approach is applicable to other non-immunogenic plant proteins

Child mortality in rural Malawi: HIV closes the survival gap between the socio-economic strata

As HIV-related deaths increase in a population the usual association between low socioeconomic status and child mortality may change, particularly as death rates from other causes decline.METHODS/PRINCIPAL FINDINGS: As part of a demographic surveillance system in northern Malawi in 2002-6, covering a population of 32,000, information was collected on socio-economic status of the households. Deaths were classified as HIV/AIDS-related or not by verbal autopsy. Poisson regression models were used to assess the association of socio-economic indicators with all-cause mortality, AIDS-mortality and non-AIDS mortality among children. There were 195 deaths in infants, 109 in children aged 1-4 years, and 38 in children aged 5-15. All-cause child mortality in infants and 1-4 year olds was similar in households with higher and lower socio-economic status. In infants 13% of deaths were attributed to AIDS, and there were no clear trends with socio-economic status for AIDS or non-AIDS causes. For 1-4 year olds 27% of deaths were attributed to AIDS. AIDS mortality was higher among those with better built houses, and lowest in those with income from farming and fishing, whereas non-AIDS mortality was higher in those with worse built houses, lowest in those with income from employment, and decreased with increasing household assets.CONCLUSIONS/SIGNIFICANCE: In this population, since HIV infection among adults was initially more common among the less poor, childhood mortality patterns have changed. The usual gap in survival between the poor and the less poor has been lost, but because the less poor have been disproportionately affected by HIV, rather than because of relative improvement in the survival of the poorest

Key features of palliative care service delivery to Indigenous peoples in Australia, New Zealand, Canada and the United States: A comprehensive review

Background: Indigenous peoples in developed countries have reduced life expectancies, particularly from chronic diseases. The lack of access to and take up of palliative care services of Indigenous peoples is an ongoing concern. Objectives: To examine and learn from published studies on provision of culturally safe palliative care service delivery to Indigenous people in Australia, New Zealand (NZ), Canada and the United States of America (USA); and to compare Indigenous peoples’ preferences, needs, opportunities and barriers to palliative care. Methods: A comprehensive search of multiple databases was undertaken. Articles were included if they were published in English from 2000 onwards and related to palliative care service delivery for Indigenous populations; papers could use quantitative or qualitative approaches. Common themes were identified using thematic synthesis. Studies were evaluated using Daly’s hierarchy of evidence-for-practice in qualitative research. Results: Of 522 articles screened, 39 were eligible for inclusion. Despite diversity in Indigenous peoples’ experiences across countries, some commonalities were noted in the preferences for palliative care of Indigenous people: to die close to or at home; involvement of family; and the integration of cultural practices. Barriers identified included inaccessibility, affordability, lack of awareness of services, perceptions of palliative care, and inappropriate services. Identified models attempted to address these gaps by adopting the following strategies: community engagement and ownership; flexibility in approach; continuing education and training; a whole-of-service approach; and local partnerships among multiple agencies. Better engagement with Indigenous clients, an increase in number of palliative care patients, improved outcomes, and understanding about palliative care by patients and their families were identified as positive achievements. Conclusions: The results provide a comprehensive overview of identified effective practices with regards to palliative care delivered to Indigenous populations to guide future program developments in this field. Further research is required to explore the palliative care needs and experiences of Indigenous people living in urban areas

The Psychological Impact of Austerity: A Briefing Paper

This report directly links cuts to public services with mental health problems. Well-established psychological research that explains these links already exists. However, this knowledge has been missing from the debate on austerity so far. Psychologists are often in a position to see the effects that social and economic changes have on people. We also occupy a relatively powerful position as professionals and therefore have an ethical responsibility to speak out about these effects. Key conclusions: Austerity policies have damaging psychological costs. Mental health problems are being created in the present, and further problems are being stored for the future. We have identified five ‘Austerity Ailments’. These are specific ways in which austerity policies impact on mental health: 1. Humiliation and shame 2. Fear and distrust 3. Instability and insecurity 4. Isolation and loneliness 5. Being trapped and powerless These experiences have been shown to increase mental health problems. Prolonged humiliation following a severe loss trebles the chance of being diagnosed with clinical depression. Job insecurity is as damaging for mental health as unemployment. Feeling trapped over the long term nearly trebles the chances of being diagnosed with anxiety and depression. Low levels of trust increase the chance of being diagnosed with depression by nearly 50 per cent. These five ‘ailments’ are indicators of problems in society, of poisonous public policy, weakness of social cohesion and inequalities in power and wealth. We also know what kind of society promotes good health. Key markers are that societies are equal, participatory and cohesive. Some important indicators of a psychologically healthy society are: 1. Agency 2. Security 3. Connection 4. Meaning 5. Trust Mental health isn’t just an individual issue. To create resilience and promote wellbeing, we need to look at the entirety of the social and economic conditions in which people live

Advancing Research Methodology and Educational Policy: An Application of Mixture Modeling Using School Climate

School climate is a well-studied issue in educational research. However, surveys of school climate tend to be analyzed using item-centered as opposed to person-centered methods. The current study evaluated the 2018 South Carolina School Climate Survey using advanced applications of mixture modeling in an attempt to identify latent profiles at the student and school levels. The relatively new manual BCH 3-Step approach was applied given its usefulness in analyzing multilevel data with covariates and distal outcomes. However, its application to multilevel mixture models leaves room for advancement and prompted the adoption of an alternative analysis plan that included separate analyses for students and schools. A latent profile analysis was conducted at the student level and resulted in the identification of six student profiles. At the school level, the manual BCH 3-Step process was applied, allowing for the incorporation of a covariate for school poverty level and distal outcomes related to academic achievement. Two profiles were identified at the school level, but because schools were also assigned to \u27known classes\u27 based on type (elementary, middle, high), a total of six profiles were created and analyzed in relation to the covariate and distal outcomes. A discussion of the results and methodological challenges associated with this study follows alongside considerations about how school climate can and should be analyzed, interpreted, and applied from both methodological and policy perspectives
