    MGG: Accelerating Graph Neural Networks with Fine-grained intra-kernel Communication-Computation Pipelining on Multi-GPU Platforms

    The increasing size of input graphs for graph neural networks (GNNs) highlights the demand for using multi-GPU platforms. However, existing multi-GPU GNN systems optimize the computation and communication individually based on the conventional practice of scaling dense DNNs. For irregularly sparse and fine-grained GNN workloads, such solutions miss the opportunity to jointly schedule/optimize the computation and communication operations for high-performance delivery. To this end, we propose MGG, a novel system design to accelerate full-graph GNNs on multi-GPU platforms. The core of MGG is its novel dynamic software pipeline to facilitate fine-grained computation-communication overlapping within a GPU kernel. Specifically, MGG introduces GNN-tailored pipeline construction and GPU-aware pipeline mapping to facilitate workload balancing and operation overlapping. MGG also incorporates an intelligent runtime design with analytical modeling and optimization heuristics to dynamically improve the execution performance. Extensive evaluation reveals that MGG outperforms state-of-the-art full-graph GNN systems across various settings: on average 4.41X, 4.81X, and 10.83X faster than DGL, MGG-UVM, and ROC, respectively

    The Perceptions of Teachers and Administrators Regarding the Influences Contributing to the High Dropout Rates of English Language Learners

    There is a high dropout rate of English language learners (ELLs) compared to non-ELLs at the school under study. Guided by Bass and Burns’s transformational leadership conceptual framework, this qualitative study aimed to examine the perceptions of administrators and teachers regarding the influences contributing to the high dropout rate of ELLs. Two research questions were employed to investigate the perceptions of administrators and teachers regarding the underlying reasons for the elevated dropout rate of ELLs at the study site school as well as examine what administrators and teachers believe causes the high dropout rates of ELLs at the high school and what tools teachers think are needed from administrators to lower the ELLs’ dropout rate. Participants were five administrators and five high school teachers who all work with ELLs. Data were collected through participant interviews and analyzed using thematic analysis. The results indicated the importance of transformational leadership in supporting teachers to improve the quality of instruction provided to ELLs. The results also showed the importance of adult and child relationships in improving the graduation rate of ELLs. The findings were used to develop professional development (PD) training for high school educators on strategies that can be used to support ELLs and help improve their graduation rate, such as developing partnerships with families of ELLs. It is recommended that school leaders provide meaningful PD that can help improve the quality of instruction ELLs receive to improve their graduation rate. The project contributes to positive social change by providing research-based strategies that teachers can use to improve the graduation rates of ELLs

    Evaluating Architectural Safeguards for Uncertain AI Black-Box Components

    Although tremendous progress has been made in Artificial Intelligence (AI), it entails new challenges. The growing complexity of learning tasks requires more complex AI components, which increasingly exhibit unreliable behaviour. In this book, we present a model-driven approach to model architectural safeguards for AI components and analyse their effect on the overall system reliability

    Crisis for Whom?

    Children feature centrally in the ubiquitous narratives of ‘migration crises’. They are often depicted as essentially vulnerable and in need of special protections, or suspiciously adult-like and a threat to national borders. At the same time, many voices, experiences, and stories are rarely heard, especially about children on the move within the global South. This bilingual book, written in English and Spanish, challenges simplistic narratives to enrich perspectives and understanding. Drawing on collaborations between young (im)migrants, researchers, artists and activists, this collection asks new questions about how crises are produced, mobility is controlled, and childhood is conceptualised. Answers to these questions have profound implications for resources, infrastructures, and relationships of care. Authors offer insights from diverse global contexts, painting a rich and insightful tapestry about childhood (im)mobility. They stress that children are more than recipients of care and that the crises they face are multiple and stratifying, with long historical roots. Readers are invited to understand migration as an act of concern and love, and to attend to how the solidarities between citizens and ‘others’, adults and children, and between children, are understood and forged.La niñez ocupa un lugar central en las narrativas omnipresentes de las ""crisis migratorias"". A menudo ésta es representada como esencialmente vulnerable y necesitada de protección especial, como sospechosamente parecida a los adultos, o como una amenaza para las fronteras nacionales. Al mismo tiempo, existen muchas voces, experiencias e historias que rara vez son escuchadas, especialmente aquellas que hablan sobre las infancias en movimiento dentro del Sur global. 'Este libro bilingüe, escrito en inglés y español, desafía las narrativas simplistas para enriquecer nuestra perspectivas y comprensión. Basada en colaboraciones entre jóvenes (in)migrantes, investigadores, artistas y activistas, esta colección plantea nuevas preguntas sobre cómo se producen las crisis, cómo se controla la movilidad y cómo se conceptualiza a la infancia y la niñez. Las respuestas a estas preguntas tienen profundas implicaciones para la distribución de recursos, la infraestructura y las prácticas de cuidado. Las y los autores ofrecen perspectivas que surgen de diversos contextos globales, construyendo un rico y detallado tapiz sobre la (in)movilidad infantil. Destacan que niñas y niños son mucho más que simples receptores de cuidados y que las crisis que enfrentan son múltiples y estratificadas, con profundas raíces históricas. Se invita a las/os lectoras/es a entender la migración como un acto de concientización y amor, y a poner atención en cómo se entienden y forjan las solidaridades entre ciudadanos y aquellos que son percibidos como “otros”; entre adultos y niñas/os, y entre las/os niñas/os mismas/os

    Pharmacy Manager System Implementation Strategies to Mitigate the Cost of Prescription Errors

    AbstractOne of the most frequent medical errors in contemporary medicine is incorrect prescriptions, and the profits from retail pharmacy operations are adversely impacted by the costs associated with prescription errors. Independent pharmacy managers are interested in finding workable strategies to mitigate the cost of prescription errors and increase profit. Using the resource-based theory of competitive advantage (RBTCA), the purpose of this qualitative multiple-case study was to explore strategies some independent pharmacy managers in Texas use to mitigate the cost of pharmacy employee prescription errors and increase profitability. The participants were five independent pharmacy managers who implemented strategies to mitigate the cost of prescription errors. Data were collected using semistructured, face-to-face interviews, a review of company documents, and site observation notes. Through thematic analysis, four themes emerged: (a) cost of prescription quality check and errors reduction strategy, (b) increased profitability strategy through error cost mitigation, (c) positive utilization of organization resources strategy, and (d) technology system implementation strategy to reduce prescription errors. A key recommendation is for independent pharmacy managers to involve pharmacy staff in developing the pharmacy system to promote user acceptance, which will assist in reducing prescription errors and raising profit. The implications for positive social change include the potential to mitigate the cost of prescription errors, prevent hospitalization and fatalities caused by medication errors, enhance patients’ quality of life, and boost the economy and employment opportunities in their communities
