How ethnic studies faculty use streaming video: Instructional needs, applications, and challenges

While there have been studies on faculty use of streaming video resources in academic libraries, none have focused on the specific needs of ethnic studies faculty. Using a thematic analysis of semi-structured interviews with 13 ethnic studies faculty from two public university campuses, this study found that faculty engagement with video is based upon a pedagogical strategy that responds to the specific demands and goals of ethnic studies curricula, while centering on student needs by using free resources whenever possible. Within this paradigm, faculty choose from three categories of content: key primary and secondary sources; flexible supporting sources; and current topics of interest. Understanding what motivates ethnic study faculty could be helpful as librarians work with vendors and advocate for the content that best meets instructional needs. Librarians can also help improve faculty\u27s instructional outcomes by communicating about licensing options and streaming media availability through the library

Through a Glass, Darkly:The CIA and Oral History

This article broaches the thorny issue of how we may study the history of the CIA by utilizing oral history interviews. This article argues that while oral history interviews impose particular demands upon the researcher, they are particularly pronounced in relation to studying the history of intelligence services. This article, nevertheless, also argues that while intelligence history and oral history each harbour their own epistemological perils and biases, pitfalls which may in fact be pronounced when they are conjoined, the relationship between them may nevertheless be a productive one. Indeed, each field may enrich the other provided we have thought carefully about the linkages between them: this article's point of departure. The first part of this article outlines some of the problems encountered in studying the CIA by relating them to the author's own work. This involved researching the CIA's role in US foreign policy towards Afghanistan since a landmark year in the history of the late Cold War, 1979 (i.e. the year the Soviet Union invaded that country). The second part of this article then considers some of the issues historians must confront when applying oral history to the study of the CIA. To bring this within the sphere of cognition of the reader the author recounts some of his own experiences interviewing CIA officers in and around Washington DC. The third part then looks at some of the contributions oral history in particular can make towards a better understanding of the history of intelligence services and the CIA

Viking Spacecraft Mission to Mars Collection of Lula Agee : A Collection Guide

During the summer of 2006, the Poynter Library received a small donation of materials related to the National Aeronautics and Space Administration (NASA) and the Viking space missions of the mid-1970s. Lula R. Agee, a NASA employee of more than twenty years based at the Langley Research Center in Hampton, Virginia, collected these materials during her tenure as a conference coordinator at that location

Evidence for a multilayered internal structure of the chondritic acapulcoite-lodranite parent asteroid

We report a petrography, mineral chemistry, oxygen and chromium isotopic study of Grove Mountains (GRV) 020043 together with a subset of other acapulcoites and lodranites. GRV 020043 is a petrologic type 4 chondrite, with chondrules of diverse types and sizes, and is composed of low-Ca pyroxene (40 vol.%), olivine (24 vol.%), diopside (8 vol.%), plagioclase (10 vol.%), Fe-Ni metal (kamacite and taenite), troilite and some accessory minerals (chromite and apatite). The olivine in GRV 020043 has an average fayalite content (Fa) of 10.7 mol.% with the low-Ca pyroxene having an average ferrosilite content (Fs) of 10.8 mol.%. The whole rock oxygen isotopic composition of GRV 020043 is +3.226 +/- 0.267 parts per thousand, +0.797 +/- 0.131 parts per thousand, and -0.927 +/- 0.017 parts per thousand for delta O-18, delta O-17, and Delta O-17, respectively, with a bulk chromium isotopic compositions of epsilon Cr-54 = -0.48 +/- 0.10. These characteristics of GRV 020043 are different from all established or ungrouped chondrites but agree with those of the acapulcoite-lodranite clan. We therefore suggest that GRV 020043 represents the chondritic precursor of acapulcoite-lodranite parent body. The similarity of bulk oxygen and chromium isotopic compositions among GRV 020043, Acapulco, Northwest Africa (NWA) 468 (metal-rich lodranite), NWA 8118 (lodranite), NWA 8287 (acapulcoite), and NWA 8422 (lodranite) indicates that they originated from a common oxygen and chromium reservoir in the protoplanetary disk or may have derived from a parent body with a differentiated multilayer structure.
