Writing centers have long been rich sites of critical inquiry into individualized instructional styles and methods. One of the great writing center debates involves directive versus nondirective tutoring styles and methods. While many writing center scholars have discussed the intricacies of directive or interventionist versus nondirective or minimalist pedagogical methods, few have examined the rhetorical implications of this important debate in relation to more classroom-based peer collaborations. This article rhetorically analyzes the literature on directive/nondirective methods and various approaches to tutoring writing, drawing pedagogical and rhetorical connections and implications useful for all teachers of writing and rhetoric. © 2013 Copyright Taylor & Francis Group, LLC.

Age and portion size have been found to influence food intake in American children but have not been examined in an international context. This study evaluated the association between age and the effects of portion size on the food intake of kindergarteners in Kunming, China. Using a within-subjects crossover design in a classroom setting, 173 children in two age groups, mean age 4.2 years and 6.1 years, were served a predefined reference, small (-30%) and large (+30%) portion of rice, vegetables, and a protein source during lunchtime over three consecutive days. Each portion was weighed before and after the meal to determine amount of food consumed. Linear mixed modeling, controlling for repeated measures and clustering by classroom, was used to compare food intake under small and large portion size conditions to the reference portion. Children ate significantly less food when served small portions. When served a large portion, 6-year-old children increased food intake while 4-year-old children decreased food intake in comparison to the reference portion. Findings indicate that portion size affects food intake in Chinese children 4-6-years old. Older children show larger increases in food intake with increased portion size than do younger children.

Vast and fast technological advancements mark the new millennium. New emerging technologies are changing the world and our society at a magnitude and scope never witnessed before. Who are our students in this new millennium? What do they look like? Are they a fundamentally different new generation as some claim, or do they still look similar to us in many ways? A clear understanding of the characteristics of our students is vitally important for our educational practice. The current study was conducted to contribute to this understanding. The findings of the study show that while students nowadays do enjoy a much broader access to new technology than students of the past, they still look similar to us in many ways. As educators, it is important for us to treat our students as individuals instead of just labeling them and placing them in a black and white dichotomy.

While the knowledge that has been gained from previous studies has accelerated the understanding of the difficulties facing individuals with Autism Spectrum Disorders (ASDs), there is concern regarding the speed with which and the overall lack of translation of research into interventions that make differences in the everyday lives of individuals with ASDs (Gresham, et al., 2001; Volkmar, et al., 2004; Volkmar, Reichow, & Doehring, 2011). For example, the symptoms of ASDs can greatly impair an individual’s ability to navigate independently through everyday events. Translating this knowledge into instructional practice requires, then, the design of methods for easing students’ transitions within the school, home, and community. While research has validated the use of low-tech visual supports (e.g., National Autism Center, 2009), little has been done to analyze the utility and appropriateness of high-tech assistive technology, such as those interventions administered through smartphones, tablets, and other handheld devices, which are devices that are being used more frequently in education settings (Gray et al., 2010). This chapter presents the results of federally funded research to determine whether the use of iPrompts—a software application for iOS and Android-based smartphones and tablet computers—assists teachers and other educational professionals as they help students with ASD transition from one activity to the next or from one setting to another.

Mauve was the first synthetic organic dyestuff to be manufactured industrially. It was synthesized in 1856 by William H. Perkin. It is composed by different molecules named mauveine A, B, B2 and C. In this study, the dye was synthesized, and its individual components were analyzed by ordinary Raman spectroscopy (both dispersive and Fourier-transform-), and surface-enhanced Raman spectroscopy, after separation by thin-layer chromatography. Only surface-enhanced Raman scattering (SERS) gave rise to satisfactory Raman spectra of the dye. Five different fractions were separated on the thin layer chromatography plate, and Raman and SERS measurements were carried out directly on each separated spot on the plate. As in the analysis of the raw product of the synthesis, only SERS gave high quality Raman spectra for the eluted spots. The assignment of the normal modes of mauveine was aided by performing density functional theory calculations. Copyright © 2014 John Wiley & Sons, Ltd.

For Italian immigrants and their descendants, needlework represents a marker of identity, a cultural touchstone as powerful as pasta and Neapolitan music. Out of the artifacts of their memory and imagination, Italian immigrants and their descendants used embroidering, sewing, knitting, and crocheting to help define who they were and who they have become. This book is an interdisciplinary collection of creative work by authors of Italian origin and academic essays. The creative works from thirty-seven contributors include memoir, poetry, and visual arts while the collection as a whole explores a multitude of experiences about and approaches to needlework and immigration from a transnational perspective, spanning the late nineteenth century to the late twentieth century. At the center of the book, over thirty illustrations represent Italian immigrant women's needlework. The text reveals the many processes by which a simple object, or even the memory of that object, becomes something else through literary, visual, performance, ethnographic, or critical reimagining. While primarily concerned with interpretations of needlework rather than the needlework itself, the editors and contributors to Embroidered Stories remain mindful of its history and its associated cultural values, which Italian immigrants brought with them to the United States, Canada, Australia, and Argentina and passed on to their descendants.
