    Our Words Matter: The Impact of Professional Development on Positive Teacher Language

    Get PDF
    Research shows that quality student-teacher relationships contribute to students’ academic, behavioral, and social-emotional outcomes. During phase 1 of this Improvement Science study, Buck Mountain Elementary School adults expressed concern with student-adult relationships. Specifically, adults indicated that connectedness with students has deteriorated since the onset of learning in a COVID 19 impacted context. Next, phase 2 investigated the impact of professional development on positive teacher language as an effective strategy to increase quality student-teacher relationships. Using a participatory-classroom action research method, participants engaged in a five-session intervention cycle of professional development focused on positive teacher language to support teachers in rebuilding quality student-teacher relationships. The scholarly practitioner performed pre-and post-intervention observations with participants to evaluate if professional development is a viable intervention to increase positive teacher language. Additionally, each participant engaged in a process understanding survey to identify how to improve the professional development process if results indicated a viable intervention. The scholarly practitioner found that professional development is a viable intervention to increase positive teacher language. The quantitative data collected during the pre and post-intervention observations supported the results, demonstrating an average change of +21. Furthermore, results of a paired sample t-test indicated a statistically significant increase in participants’ use of positive teacher language from pre-intervention (m = 1.99, sd = .89) to post-intervention (m = 4.09, sd = 1.35). The mean increase of positive teacher language was 2.1 t (8) = -8.91, p \u3c .001. The process understanding survey concluded that professional development could be improved by providing additional instruction on adult and student social-emotional competencies, additional collaboration among staff members, and additional professional development that is applicable, can be embedded over time, explicit delivery methods, and supports the collaboration of staff. Results analyzed during phases 1 and 2 of this Improvement Science study imply that professional development is a viable intervention to increase positive teacher language. Recommendations for future research and practice include studies investigating the impact of positive teacher language on supporting quality student-teacher relationships, utilizing professional development as an intervention for a different problem of practice, and implementing the theory of improvement in a different educational setting. Finally, professional development should be developed for an explicit purpose with a specific framework to increase professional learning

    From GenderMag to InclusiveMag: An Inclusive Design Meta-Method

    How can software practitioners assess whether their software supports diverse users? Although there are empirical processes that can be used to find “inclusivity bugs” piecemeal, what is often needed is a systematic inspection method to assess software’s support for diverse populations. To help fill this gap, this paper introduces InclusiveMag, a generalization of GenderMag that can be used to generate systematic inclusiveness methods for a particular dimension of diversity. We then present a multicase study covering eight diversity dimensions, of eight teams’ experiences applying InclusiveMag to eight under-served populations and their “mainstream” counterparts

    Can forest management based on natural disturbances maintain ecological resilience?

    Given the increasingly global stresses on forests, many ecologists argue that managers must maintain ecological resilience: the capacity of ecosystems to absorb disturbances without undergoing fundamental change. In this review we ask: Can the emerging paradigm of natural-disturbance-based management (NDBM) maintain ecological resilience in managed forests? Applying resilience theory requires careful articulation of the ecosystem state under consideration, the disturbances and stresses that affect the persistence of possible alternative states, and the spatial and temporal scales of management relevance. Implementing NDBM while maintaining resilience means recognizing that (i) biodiversity is important for long-term ecosystem persistence, (ii) natural disturbances play a critical role as a generator of structural and compositional heterogeneity at multiple scales, and (iii) traditional management tends to produce forests more homogeneous than those disturbed naturally and increases the likelihood of unexpected catastrophic change by constraining variation of key environmental processes. NDBM may maintain resilience if silvicultural strategies retain the structures and processes that perpetuate desired states while reducing those that enhance resilience of undesirable states. Such strategies require an understanding of harvesting impacts on slow ecosystem processes, such as seed-bank or nutrient dynamics, which in the long term can lead to ecological surprises by altering the forest's capacity to reorganize after disturbance

    The utilisation of health research in policy-making: Concepts, examples and methods of assessment

    Get PDF
    The importance of health research utilisation in policy-making, and of understanding the mechanisms involved, is increasingly recognised. Recent reports calling for more resources to improve health in developing countries, and global pressures for accountability, draw greater attention to research-informed policy-making. Key utilisation issues have been described for at least twenty years, but the growing focus on health research systems creates additional dimensions. The utilisation of health research in policy-making should contribute to policies that may eventually lead to desired outcomes, including health gains. In this article, exploration of these issues is combined with a review of various forms of policy-making. When this is linked to analysis of different types of health research, it assists in building a comprehensive account of the diverse meanings of research utilisation. Previous studies report methods and conceptual frameworks that have been applied, if with varying degrees of success, to record utilisation in policy-making. These studies reveal various examples of research impact within a general picture of underutilisation. Factors potentially enhancing utilisation can be identified by exploration of: priority setting; activities of the health research system at the interface between research and policy-making; and the role of the recipients, or 'receptors', of health research. An interfaces and receptors model provides a framework for analysis. Recommendations about possible methods for assessing health research utilisation follow identification of the purposes of such assessments. Our conclusion is that research utilisation can be better understood, and enhanced, by developing assessment methods informed by conceptual analysis and review of previous studies

    In Vivo Near-Infrared Imaging of Fibrin Deposition in Thromboembolic Stroke in Mice

    imaging of activated factor XIII (FXIIIa), an important mediator of thrombosis or fibrinolytic resistance. The present study was to investigate the fibrin deposition in a thromboembolic stroke mice model by FXIIIa–targeted near-infrared fluorescence (NIRF) imaging., which were correlated with histology after animal euthanasia. NIRF images and lesion volume.Non-invasive detection of fibrin deposition in ischemic mouse brain using NIRF imaging is feasible and this technique may provide an in vivo experimental tool in studying the role of fibrin in stroke
