Jet array impingement with crossflow-correlation of streamwise resolved flow and heat transfer distributions
Correlations for heat transfer coefficients for jets of circular offices and impinging on a surface parallel to the jet orifice plate are presented. The air, following impingement, is constrained to exit in a single direction along the channel formed by the jet orifice plate and the heat transfer (impingement) surface. The downstream jets are subjected to a crossflow originating from the upstream jets. Impingement surface heat transfer coefficients resolved to one streamwise jet orifice spacing, averaged across the channel span, are correlated with the associated individual spanwise orifice row jet and crossflow velocities, and with the geometric parameters

The educational experiences of autistic children with and without extreme demand avoidance behaviours
Extreme demand avoidance (EDA) is increasingly described as part of the autism spectrum and is sometimes diagnosed as Pathological Demand Avoidance (PDA). Yet little is known, about the educational experiences of children with and without EDA behaviours. Using an online survey collecting both quantitative and qualitative data, 211 parents reported on the school experiences of their autistic children. 57 parents had a child with an additional diagnosis of PDA (AUT-PDA); 91 had a child with no diagnosis of PDA but, according to parent report, displayed EDA behaviours (AUT-EDA); and 63 had a child with neither a PDA diagnosis nor EDA behaviours (AUT). Results demonstrated that there were few group differences in terms of the frequency of failed school placements and exclusions. However, children in the AUT-EDA/-PDA groups had higher levels of behaviour that challenges, which were particularly high in those with a PDA diagnosis. There were no significant differences in school exclusions, but the fact that these occurred across all groups is of concern. Qualitative results suggested overwhelmingly negative school experiences for all groups but especially the AUT-EDA and AUT-PDA groups. Parents attributed such experiences to misunderstanding of their children’s diagnoses and a lack of targeted support
REENGINEERING: A FRAMEWORK FOR EVALUATION AND CASE STUDY OF AN IMAGING SYSTEM
Reengineering or business process redesign has become
very popular. This paper presents a framework for comparing
and evaluating reengineering efforts. The framework is
applied to a case study of the reengineering of the
securities processing function at Merrill Lynch. The paper
compares the old and new process at Merrill. The new
process features image capture, character recognition and
extensive redesign. The reengineering effort has had a
substantial payback for the firm.Information Systems Working Papers Serie
RE-ENGINEERING: A FRAMEWORK FOR ANALYSIS AND CASE STUDY OF AN IMAGING SYSTEM
Re-engineering or business process redesign has become
very popular. This paper presents a clear description of
re-engineering and contrasts it with incremental change in
systems. The paper also develops a framework for comparing
two related systems. The framework is applied to a case
study of the re-engineering of the Merrill Lynch Securities
Processing System. This system features image processing,
character recognition and extensive process redesign. The
re-engineering effort has had a substantial impact on the

The Capaciousness of No: Affective Refusals as Literacy Practices
© 2020 The Authors. Reading Research Quarterly published by Wiley Periodicals, Inc. on behalf of International Literacy Association The authors considered the capacious feeling that emerges from saying no to literacy practices, and the affective potential of saying no as a literacy practice. The authors highlight the affective possibilities of saying no to normative understandings of literacy, thinking with a series of vignettes in which children, young people, and teachers refused literacy practices in different ways. The authors use the term capacious to signal possibilities that are as yet unthought: a sense of broadening and opening out through enacting no. The authors examined how attention to affect ruptures humanist logics that inform normative approaches to literacy. Through attention to nonconscious, noncognitive, and transindividual bodily forces and capacities, affect deprivileges the human as the sole agent in an interaction, thus disrupting measurements of who counts as a literate subject and what counts as a literacy event. No is an affective moment. It can signal a pushback, an absence, or a silence. As a theoretical and methodological way of thinking/feeling with literacy, affect proposes problems rather than solutions, countering solution-focused research in which the resistance is to be overcome, co-opted, or solved. Affect operates as a crack or a chink, a tiny ripple, a barely perceivable gesture, that can persist and, in doing so, hold open the possibility for alternative futures
