    Exploring the Dynamics of Cross-Cultural Collaboration in Writing Classrooms
    ([BREAK]Publisher of the original article: TWI Publications. Copyright © 1990, TWI Publications. From the publisher's web site: "We are committed to the open access publishing model."[BREAK], 1990) Allaei, Sara Kurtz; Connor, Ulla, 1948-
    As teachers of writing have adopted the idea that writing should be taught as a process ,from the generation of ideas to the fine-tuning of the final editing, much interest has been focused on the use of peer collaboration at various stages of the writing process, particularly in guiding students in responding to the writing of peers. Bruffee ("'Conversation'"), an early advocate of the use of peer collaboration, argues that "collaborative learning provides the kind of social context .... in which normal discourse occurs: a community of knowledgeable peers". In this context, "students can practice and master the normal discourse exercised in established communities in the academic world and in business , government and the professions" (644). Of course, students are not yet members of these established knowledge communities, but Gere argues that they can negotiate their way toward acceptable discourse: many of the comments they make as they respond to each other's writing begin with the phrase, "I don't know..." or "I don't think...". Student writers comment on and question their own work: they ask, "Does this example make sense here?", or "I'm trying to show why Joe is so alienated from his family. Does this idea come trough clearly?" (70)

    Nanoparticle toxicity by the gastrointestinal route: evidence and knowledge gaps
    (Inderscience, 2013) Bergin, Ingrid L.; Witzmann, Frank A.; Cellular and Integrative Physiology, School of Medicine
    The increasing interest in nanoparticles for advanced technologies, consumer products, and biomedical applications has led to great excitement about potential benefits but also concern over the potential for adverse human health effects. The gastrointestinal tract represents a likely route of entry for many nanomaterials, both directly through intentional ingestion or indirectly via nanoparticle dissolution from food containers or by secondary ingestion of inhaled particles. Additionally, increased utilisation of nanoparticles may lead to increased environmental contamination and unintentional ingestion via water, food animals, or fish. The gastrointestinal tract is a site of complex, symbiotic interactions between host cells and the resident microbiome. Accordingly, evaluation of nanoparticles must take into consideration not only absorption and extraintestinal organ accumulation but also the potential for altered gut microbes and the effects of this perturbation on the host. The existing literature was evaluated for evidence of toxicity based on these considerations. Focus was placed on three categories of nanomaterials: nanometals and metal oxides, carbon-based nanoparticles, and polymer/dendrimers with emphasis on those particles of greatest relevance to gastrointestinal exposures.
