Intergenerational Art Education: Building Community in Harlem

I began the first of 43 visits to an after-school intergenerational art program in Lower East Harlem, New York, with the expectation of a straight-forward research project, one which would perhaps ratify my growing conviction that young people and older adults together would provide a natural learning environment for art. My first personal encounter with the Lower East Harlem community began when I crossed 96th Street, an informal boundary separating its decaying tenements and public housing projects from the newer, more prosperous neighborhood to the south. I soon realized that there was no need for a line on the map indicating the division between Manhattan and Harlem. And referring to a travel guide of New York City, I noticed that it listed no restaurants, hotels, or shopping highlights above 96th Street. Subway tracks emerged above ground and loomed over Central Harlem\u27s neighborhoods. The only new building in the vicinity north of 96th Street was the impressive Muslim Mosque

Low-Temperature Solution-Processed Electron Transport Layers for Inverted Polymer Solar Cells

© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, WeinheimProcessing temperature is highlighted as a convenient means of controlling the optical and charge transport properties of solution processed electron transport layers (ETLs) in inverted polymer solar cells. Using the well-studied active layer – poly(3-hexylthiophene-2,5-diyl):indene-C60 bisadduct – the influence of ETL processing temperatures from 25 to 450 °C is shown, reporting the role of crystallinity, structure, charge transport, and Fermi level (EF) on numerous device performance characteristics. It has been determined that an exceptionally low temperature processed ETL (110 °C) increases device power conversion efficiency by a factor greater than 50% compared with a high temperature (450 °C) processed ETL. Modulations in device series and shunt resistance, induced by changes in the ETL transport properties, are observed in parallel to significant changes in device open circuit voltage attributed to changes on the EF of the ETLs. This work highlights the importance of interlayer control in multilayer photovoltaic devices and presents a convenient material compatible with future flexible and roll-to-roll processes

Inverse Inclusion: A Model for Preservice Art Teacher Training

A university community-based intercession course offers preservice art teachers a unique opportunity to experience inverse inclusion in an art class for special needs adults. Inverse inclusion allows preservice teachers to become students working side-by-side with an equal or greater number of special needs learners, and also places them in occasional roles as teacher, teacher’s assistant, and videographer. Their observations and interactions within these roles provide preservice teachers with perceptive insights and perspectives about teaching, and nurture a better understanding of special needs students’ personal interests and abilities. Applying, reflecting upon, and adapting open-ended art curriculum theory and practice from multiple participant perspectives suggest the potential to apply this model of inverse inclusion to preservice art education programs and research

A transient network of telechelic polymers and microspheres : structure and rheology

We study the structure and dynamics of a transient network composed of droplets of microemulsion connected by telechelic polymers. The polymer induces a bridging attraction between droplets without changing their shape. A viscoelastic behaviour is induced in the initially liquid solution, characterised in the linear regime by a stretched exponential stress relaxation. We analyse this relaxation in the light of classical theories of transient networks. The role of the elastic reorganisations in the deformed network is emphasized. In the non linear regime, a fast relaxation dynamics is followed by a second one having the same rate as in the linear regime. This behaviour, under step strain experiments, should induce a non monotonic behaviour in the elastic component of the stress under constant shear rate. However, we obtain in this case a singularity in the flow curve very different from the one observed in other systems, that we interpret in terms of fracture behaviour.Comment: 9 pages, 4 figure

Variabilité protéique observée par électrophorèse bidimensionnelle sur neuf isolats d'Heterodera schachtii provenant de six pays européens et sur deux isolats d'H. trifolii f.sp. beta

La variabilité protéique de neuf isolats européens d'#Heterodera schachtii et de deux isolats d'#H. trifolii f. sp. #beta élevés en conditions contrôlées sur colza, #Brassica napus L. var. #napus$ cv. Samouraï a été étudiée par électrophorèse bidimensionnelle (E2D). Les gels électrophorétiques sont comparés à l'aide d'un système informatique d'analyse d'images. Les indices de similarité (F) et les distances génétiques (D = 1-F) sont calculés à partir des taches homologues. Le dendrogramme est obtenu avec la méthode UPGMA. Les résultats montrent une assez grande similitude protéique des deux espèces. Les principales différences interspécifiques sont mises en évidence, ainsi que deux zones communes caractéristiques. Concernant la variabilité infraspécifique, des taches caratéristiques de certains isolats ont été repérées. La possibilité d'utiliser l'E2D pour identifier des protéines liées à la virulence est envisagée, ce qui nécessitera l'étude d'un grand nombre d'isolats. (Résumé d'auteur

Mise au point d'un microscope à effet tunnel

La conception et la réalisation d'un microscope à effet tunnel sont présentées. On discute de la partie mécanique et de la façon de réaliser l'isolation vis-à-vis des vibrations. Le comportement de la boucle d'asservissement qui contrôle la distance pointe-échantillon est analysée en détail. Les effets parasites dus aux perturbations électriques sont également pris en compte. Les possibilités de ce microscope sont démontrées avec quelques images du graphite et de métaux réalisées à l'air

Glucokinase activators (GKAs) promise a new pharmacotherapy for diabetics

The glucose-phosphorylating enzyme glucokinase, a promising target for developing new antidiabetic agents, was identified through the combined efforts of basic research and human biochemical genetics. Allosteric glucokinase activators (GKAs) were discovered by high-throughput screening of a large compound library and first reported in 2003. GKAs stimulate insulin release and glucose metabolism in the liver thereby lowering blood sugar, and promising trials in humans demonstrate that they are highly effective in patients with type 2 diabetes mellitus. Many companies are now attempting to develop effective and safe GKAs for treating diabetics

CRITICAL REVIEW ON VIDARIKAND (PUERARIA TUBEROSA DC.) -AN AYURVEDIC HERB

Background: Vidarikand is the one of the most important drug which has broadly described in detail in all the textbook of Ayurveda. It is commonly known as Indian kudzu which is a perennial climber with woody tuberculated stem with large tuberous roots. Generally all the Nighantus are mention its various properties. It is used in variety of formulation mention in Ayurvedic Samhita for the different-different purpose and treatment of diseases. There are so many researches were done on Vidarikand on range of diseases and its property. Aims and Objects: This paper trying to elaborate, evaluate and discuss the medicinal property, therapeutic effects of Vidarikanda in various diseases including new emerging problems.

Intergenerational Implications of Ritual in Art Education

This article introduces the concept of ritual and the role it can play in art education across generations from PK-12 schools to community collaborations. Three authors elaborate on research, personal experiences, and applications of ritual in their art education practice. The first introduces ritual within personal, historical, cultural, psychological, and sociological contexts. Then, relates these to art education curriculum and an intergenerational community collaboration. Author 2 shares experience with ritual-based artists using performance, body adornment and modification to communicate creative sacred/secular expression. Author 3 describes her hesitancy and eventual success in engaging preadolescents in ritual-based discussions. All of these perspectives hope to inspire readers’ ritual research and practice across generations
