No full textStaples and Jayakumar introduce this issue of the Occasional Paper Series that speaks to the #SayHerName social justice initiative. The movement aims to expose the experiences of Black and Brown girls and women who are subject to police violence in society and various violences in schools. In response to this movement, this issue includes stories of Black and Brown women from early childhood education through higher education
The Shaping of Postcollege Colorblind Orientation Among Whites: Residential Segregation and Campus Diversity Experiences
No full textIn this article, Uma M. Jayakumar investigates the cumulative impact of experiences with segregation or racial diversity prior to and during college on colorblind ideological orientation among white adults. An analysis of longitudinal data spanning ten years reveals that, for whites from segregated and diverse childhood neighborhoods, some experiences in college may increase colorblind thinking, while others may facilitate a greater understanding of the racial context of US society. Segregated white environments, or white habitus, before, during, and after college are associated with whites' colorblind ideological orientations, with negative implications for racial justice. Campus racial diversity experiences can play a role in diminishing the influence of white habitus but are not necessarily doing so. In other words, the challenges of addressing colorblind orientation are greater for white students from segregated neighborhoods and high schools who also tend to choose segregated white campus environments and are less likely to engage across race lines while in college. This study speaks to the need for more direct interventions addressing colorblind ideology among white college students. The findings suggest that racial diversity and integration are potentially disruptive but insufficient conditions for unlearning harmful colorblind frames

Sustainable machining and optimization of machining parameters utilizing different dielectrics in EDM machining of Waspaloy
No full textThis study investigates the influence of various dielectric fluids on the performance of Electric Discharge Machining (EDM) in machining Waspaloy, a corrosion-resistant superalloy known for its high hardness and enhanced corrosion resistance. The purpose of this work is to fill the knowledge gap about the machining of Waspaloy using different dielectric fluids by using a Copper-5Graphite (CuGr5) composite tools. Experiments were conducted using a EDM machine with copper graphite composite electrodes and five distinct dielectric fluids, including hydrocarbon oil, kerosene, sunflower oil, used motor oil, and groundnut oil. The effects of key process parameters such as current, voltage, pulse on time, pulse off time, and gap distance on Material Removal Rate (MRR) and Surface Roughness (Ra) were evaluated. Dielectric fluid properties, including viscosity, density, thermal conductivity, and dielectric strength, were comprehensively characterized. Results revealed that MRR increased with current and pulse-on time up to a threshold, beyond which thermal damage reduced efficiency. Sunflower oil demonstrated the most favorable performance, achieving an MRR of up to 0.570 mm(3)/min and Ra as low as 1.012 mu m, attributed to its high dielectric strength (40 kVA), moderate viscosity, and superior thermal conductivity. In contrast, kerosene and hydrocarbon oil, while effective in debris flushing, resulted in inconsistent spark stability and increased surface roughness at higher energy settings due to lower dielectric strength and flash points. Used motor oil and groundnut oil, though sustainable, exhibited higher surface roughness and limited MRR under elevated parameter settings owing to their higher viscosity and lower heat dissipation capabilities. A novel predictive equation for MRR and Ra, integrating dielectric fluid properties and machining parameters, was developed to enhance process optimization. Surface morphology analysis using SEM revealed characteristic features such as craters, recast layers, microcracks, and resolidified debris, highlighting the interplay between thermal, electrical, and mechanical effects during EDM. This research promotes sustainable manufacturing by assessing bio-based and waste-derived dielectric fluids as environmentally responsible alternatives to conventional EDM oil.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
