    Teaching Global Literature to “Disturb the Waters”: A Case Study

    Get PDF
    Within this qualitative case study, I describe how a fifth-grade teacher in an affluent and culturally homogenous school attempted to “disturb the waters” through teaching global literature. Framed by transactional theories of response and critical language awareness, I identify three central pedagogical moves that supported disruptions of students’ assumptions and beliefs: (1) inviting students to share their aesthetic transactions, (2) privileging multiple perspectives and genres, and (3) calling attention to language choices as a central line of inquiry. I argue that both transactional and critical approaches to literacy and language are necessary in order to move students beyond disinterested and prejudicial responses to global literature and to challenge commonly held beliefs

    The strategic potential of community-based hybrid models: the case of global business services in Africa

    Get PDF
    Firms in latecomer economies, such as Sub-Saharan Africa, often have limited success with traditional business models. We explain why it can be more feasible to adopt a hybrid model in such a region that combines profitability with serving local communities, e.g., by promoting inclusive employment or by targeting underserved markets. Sub-Saharan Africa supports hybrid models and social enterprises mainly through local community resources (e.g., labor, market ideas), community organizations giving access to such resources, and experience with business-community alliances. Hybrid models can benefit from such conditions when business clients and governments support the social mission and when firms are ready to target niche rather than mainstream markets. We illustrate the business potential of hybrid enterprises based on the case of ‘impact sourcing’ in global business services in Kenya and South Africa

    Seasonal changes in patterns of gene expression in avian song control brain regions.

Little is known, however, about the patterns of gene expression associated with seasonal changes. Here we address this issue by altering the hormonal and photoperiodic conditions in seasonally-breeding Gambel's white-crowned sparrows and extracting RNA from the telencephalic song control nuclei HVC and RA across multiple time points that capture different stages of growth and regression. We chose HVC and RA because while both nuclei change in volume across seasons, the cellular mechanisms underlying these changes differ. We thus hypothesized that different genes would be expressed between HVC and RA. We tested this by using the extracted RNA to perform a cDNA microarray hybridization developed by the SoNG initiative. We then validated these results using qRT-PCR. We found that 363 genes varied by more than 1.5 fold (>log(2) 0.585) in expression in HVC and/or RA. Supporting our hypothesis, only 59 of these 363 genes were found to vary in both nuclei, while 132 gene expression changes were HVC specific and 172 were RA specific. We then assigned many of these genes to functional categories relevant to the different mechanisms underlying seasonal change in HVC and RA, including neurogenesis, apoptosis, cell growth, dendrite arborization and axonal growth, angiogenesis, endocrinology, growth factors, and electrophysiology. This revealed categorical differences in the kinds of genes regulated in HVC and RA. These results show that different molecular programs underlie seasonal changes in HVC and RA, and that gene expression is time specific across different reproductive conditions. Our results provide insights into the complex molecular pathways that underlie adult neural plasticity

    Origin and insertion of the medial patellofemoral ligament: a systematic review of anatomy.

    PURPOSE: The medial patellofemoral ligament (MPFL) is the major medial soft-tissue stabiliser of the patella, originating from the medial femoral condyle and inserting onto the medial patella. The exact position reported in the literature varies. Understanding the true anatomical origin and insertion of the MPFL is critical to successful reconstruction. The purpose of this systematic review was to determine these locations. METHODS: A systematic search of published (AMED, CINAHL, MEDLINE, EMBASE, PubMed and Cochrane Library) and unpublished literature databases was conducted from their inception to the 3 February 2016. All papers investigating the anatomy of the MPFL were eligible. Methodological quality was assessed using a modified CASP tool. A narrative analysis approach was adopted to synthesise the findings. RESULTS: After screening and review of 2045 papers, a total of 67 studies investigating the relevant anatomy were included. From this, the origin appears to be from an area rather than (as previously reported) a single point on the medial femoral condyle. The weighted average length was 56 mm with an 'hourglass' shape, fanning out at both ligament ends. CONCLUSION: The MPFL is an hourglass-shaped structure running from a triangular space between the adductor tubercle, medial femoral epicondyle and gastrocnemius tubercle and inserts onto the superomedial aspect of the patella. Awareness of anatomy is critical for assessment, anatomical repair and successful surgical patellar stabilisation. LEVEL OF EVIDENCE: Systematic review of anatomical dissections and imaging studies, Level IV

    Organizing risk: organization and management theory for the risk society

    Get PDF
    Risk has become a crucial part of organizing, affecting a wide range of organizations in all sectors. We identify, review and integrate diverse literatures relevant to organizing risk, building on an existing framework that describes how risk is organized in three ‘modes’ – prospectively, in real-time, and retrospectively. We then identify three critical issues in the existing literature: its fragmented nature; its neglect of the tensions associated with each of the modes; and its tendency to assume that the meaning of an object in relation to risk is singular and stable. We provide a series of new insights with regard to each of these issues. First, we develop the concept of a risk cycle that shows how organizations engage with all three modes and transition between them over time. Second, we explain why the tensions have been largely ignored and show how studies using a risk work perspective can provide further insights into them. Third, we develop the concept of risk translation to highlight the ways in the meanings of risks can be transformed and to identify the political consequences of such translations. We conclude the paper with a research agenda to elaborate these insights and ideas further
