Historicizing Fear
No full textHistoricizing Fear is a historical interrogation of the use of fear as a tool to vilify and persecute groups and individuals from a global perspective, offering an unflinching look at racism, fearful framing, oppression, and marginalization across human history. The book examines fear and Othering from a historical context, providing a better understanding of how power and oppression are used in the present day.
Contributors ground their work in the theory of Othering—the reductive action of labeling a person as someone who belongs to a subordinate social category defined as the Other—in relation to historical events, demonstrating that fear of the Other is universal, timeless, and interconnected. Chapters address the music of neo-Nazi white power groups, fear perpetuated through the social construct of black masculinity in a racially hegemonic society, the terror and racial cleansing in early twentieth-century Arkansas, the fear of drug-addicted Vietnam War veterans, the creation of fear by the Tang Dynasty, and more.
Timely, provocative, and rigorously researched, Historicizing Fear shows how the Othering of members of different ethnic groups has been used to propagate fear and social tension, justify state violence, and prevent groups or individuals from gaining equality. Broadening the context of how fear of the Other can be used as a propaganda tool, this book will be of interest to scholars and students of history, anthropology, political science, popular culture, critical race issues, social justice, and ethnic studies, as well as the general reader concerned with the fearful framing prevalent in politics.

An Effective Methodology for Thermal-Hydraulics Analysis of a VHTR Core and Fuel Elements
No full textThe Very High Temperature Reactor (VHTR) is a Generation-IV design in the conceptual pre-licensing phase for potential construction by 2030-2050. It is graphite moderated, helium cooled reactor that operates at an exit temperature of up to 1273 K, making it ideal for generating electricity at a plant thermal efficiency upwards of 48% and the co-generation of process heat for hydrogen production and other industrial uses. Extensive thermal-hydraulics and safety analyses of VHTRs are being conducted using Computational Fluid Dynamics (CFD) and heat transfer codes, in conjunction with experiments and prototype demonstrations. These analyses are challenging, largely due to the 3-D simulation of the helium flow in the 10 m long coolant channels in the reactor core and the need to examine the effects of helium bypass flow in the interstitial gaps between the core fuel elements. This research, performed at the UNM-ISNPS, developed an effective thermal-hydraulics analyses methodology that markedly reduces the numerical meshing requirements and computational time. It couples the helium’s 1-D convective flow and heat transfer in the channels to 3-D heat conduction in graphite and fuel compacts of VHTR fuel elements. Besides the helium local bulk temperature, the heat transfer coefficient is calculated using a Nusselt number correlation, developed and validated in this work. In addition to omitting the numerical meshing in the coolant channels, the simplified analysis methodology effectively decreases the total computation time by a factor of ~ 33 - 40 with little effect on the calculated temperatures (< 5 K), compared to a full 3-D thermal-hydraulics analysis.
The developed convective heat transfer correlation accounts for the effect of entrance mixing in the coolant channels, where z/D < 25. The correlation compares favorably, to within + 12%, with Taylor’s (based on high temperature hydrogen heat transfer) and to within + 2% of the calculated results for full 3-D analyses of a VHTR single channel module and multiple channels in the fuel elements. The simplified methodology is used to investigate the effects of helium bypass flow in interstitial gaps between fuel elements and of the helium bleed flow in control rod channels on calculated temperatures in the VHTR fuel elements. Thermal-hydraulics analysis of a one-element high and of a full height VHTR 1/6 core are also conducted. Results show that the interstitial bypass flow increases the temperatures near the center of the core fuel elements by 10-15 K, while reducing the temperatures along the edges of the elements by ~30 K. Without bypass flow, hotspots may occur at the location of burnable poison rods in the fuel elements, depending on the assumed volumetric heat generation rate in the rods. The helium bleed flow through the control rod channels reduces temperatures near them by 2-5 K, and only slightly increases the temperatures within the rest of the core fuel elements. In the VHTR 1/6 core thermal-hydraulics analysis, the helium bypass flow decreases the heat transfer from the core fuel elements to the adjacent radial graphite reflector blocks. Results demonstrate the effectiveness of the developed methodology and its potential use in future thermal-hydraulics design and in the safety analyses of VHTRs.Institute for Space and Nuclear Power Studies, Department of Energy - Nuclear Energy University Programs, Nuclear Regulatory Commission - Graduate FellowshipsNuclear EngineeringMastersUniversity of New Mexico.

Research fronts in library and information science in Spain
No full textPublications and author cocitations in library and information science in Spain during the period from 1985 to 1994 were analyzed as a measure of the structure, specificity and composition of research fronts in this country. A cocitation matrix developed from an ad hoc database was subjected to cluster analysis, multidimensional scaling and principal components analysis, The resulting cocitation maps identified specific areas of r~search and their knowledge bases. We inferred the degree of consolidation of the discipline of library and information science, and of the subdisciplines informetrics, librarianship and university affiliation, from the research activities revealed. In this respect, the conclusions from the study show the existence of several research fronts in Spanish literature the contents of which are in most cases difficult to compare with those in other countries. A lesser degree of maturity of research in this field is shown

No full textGuest Editorial: Cruel Summer
No full text2020 has been one of the most eventful and consequential years in the United States as well as around the world. Along with COVID-19, the sociopolitical climate that has allowed White supremacy and cruelty to thrive consequently resulted in a Cruel Summer. As we reflect on this Cruel Summer, popular culture can serve as a powerful lens to understand history as well as our contemporary world. We must remain vigilant and use our scholarship to push back against anti-Black racism and White supremacy. I look forward to your thoughts on this issue and hope you enjoy, Engaged Popular Culture and Pedagogy: Awareness, Understanding and Social Justice
