Building a User Testing Toolkit at Your Consortium or Institution

An increasing number of Orbis Cascade Alliance libraries have either begun performing user testing or have an interest in doing so. The User Testing Toolkit Project Group (UTTPG) was formed to build a user testing toolkit to support user testing at Alliance libraries. In our presentation, we will talk about our process for collaborating as a group of representatives from the diverse academic institutions that make up the Alliance consortium, the resources we found useful including: how to’s, software recommendations, sample documentation and resources for instruction reference staff, and share the webpage where our toolkit is available

The Camden African-American Heritage Project

This report is divided into six sections that present a history of African Americans in Camden, South Carolina from the perspective of historic preservation. The first three sections constitute the historical narrative, organized into three general time periods: the colonial period through the Civil War, emancipation and Reconstruction through the civil rights movement, and a short section on the recent past since about 1970. Within each of these sections, the report assesses political participation, economic life, the impact of war, education, religion, and the built environment. Section four offers a set of recommendations for how the information in this report can be used to encourage public education about black Camden and preservation of the city‘s African-American historic resources. The primary and secondary sources consulted in this study are listed in the bibliography in section five. The appendix in section six contains a map and database of black Camden in 1941, based on the treasure trove of information in the city directory of that year.https://scholarcommons.sc.edu/pubhist_books/1001/thumbnail.jp

Cardiophysiological responses of the air-breathing Alaska blackfish to cold acclimation and chronic hypoxic submergence at 5°C

The Alaska blackfish (Dallia pectoralis) remains active at cold temperatures when experiencing aquatic hypoxia without air access. To discern the cardiophysiological adjustments that permit this behaviour, we quantified the effect of acclimation from 15°C to 5°C in normoxia (15N and 5N fish), as well as chronic hypoxic submergence (6-8 weeks; ∼6.3-8.4 kPa; no air access) at 5°C (5H fish), on in vivo and spontaneous heart rate (fH), electrocardiogram, ventricular action potential (AP) shape and duration (APD), the background inward rectifier (IK1) and rapid delayed rectifier (IKr) K+ currents and ventricular gene expression of proteins involved in excitation-contraction coupling. In vivo fH was ∼50% slower in 5N than in 15N fish, but 5H fish did not display hypoxic bradycardia. Atypically, cold acclimation in normoxia did not induce shortening of APD or alter resting membrane potential. Rather, QT interval and APD were ∼2.6-fold longer in 5N than in 15N fish because outward IK1 and IKr were not upregulated in 5N fish. By contrast, chronic hypoxic submergence elicited a shortening of QT interval and APD, driven by an upregulation of IKr. The altered electrophysiology of 5H fish was accompanied by increased gene expression of kcnh6 (3.5-fold; Kv11.2 of IKr), kcnj12 (7.4-fold; Kir2.2 of IK1) and kcnj14 (2.9-fold; Kir2.4 of IK1). 5H fish also exhibited a unique gene expression pattern that suggests modification of ventricular Ca2+ cycling. Overall, the findings reveal that Alaska blackfish exposed to chronic hypoxic submergence prioritize the continuation of cardiac performance to support an active lifestyle over reducing cardiac ATP demand. © 2020.

An Examination of Early Childhood Teachers’ Perceptions of Discussing Race with Children

This qualitative study examines early childhood teachers’ perceptions and practices with regard to talking to young children about race. Through an online survey and an individual interview with two early childhood teachers, I uncovered three findings: a) teachers’ understandings of their students’ racial awareness, b) teachers’ current classroom practices regarding race, culture, ethnicity, and c) challenges teachers faced in talking about race with their students along with possible sources of support. Based on these findings, I concluded that teachers made the decision not to directly confront the issue of race with their students due to feelings of fear and discomfort. As white women, the participants were able to choose when to engage with race, in contrast to people of color who confront racism daily. Secondly, the teachers demonstrated efforts to respond to the racial and cultural diversity in their classrooms and affirm their students’ identities, although they did not support their students’ development of sociopolitical consciousness. The work of anti-racist and culturally responsive pedagogy exists along a spectrum, with much more work needed in taking up the most difficult aspects of the approach which require constant self-reflection and the willingness to step outside one’s comfort zone

The Impression That I Get: Reference & Instruction Uses / Preceptions of Primo in a Consortial Environment

The Discovery and User Experience Team conducted an open-ended survey designed to gather information about how Primo works within the context of the daily work of patron-centered staff and librarians. We felt that this information and feedback was important because it provided the only avenue in which reference and instruction librarians could give direct input to the Alliance about how to improve our current discovery interface. The survey asked reference and instruction librarians about their specific experiences with Primo with the goal of identifying ways that the Discovery and User Experience Team could better support these users
