    The Data Literacy Advisory Team at Virginia Tech: Developing a Content Model for Data Literacy Instruction
    Ogier, Andrea; Lener, Edward F.; Miller, Rebecca K. (2013-09-20)
    In Spring 2013, the Center for Digital Research and Scholarship and the University Libraries at Virginia Tech formed a Data Literacy Advisory Team (DLAT) composed of reference, instruction, collections, data services and subject librarians and library specialists. Tasked with developing an instructional framework for delivering research and data-related content to faculty, staff and students (both graduate and undergraduate) in the univeristy-at-large, DLAT began by developing a skill-focused content model that could be used at different levels of instruction for audiences at varying levels of experience. The skill-focused model allows library instructors to select curated content out of the modular framework, and allows them to further shape and refine according to their instructional needs. This poster will present that model, include learning outcomes and assessments formulated by DLAT, and demonstrate how the model could be used to create a lesson on-the-fly.

    Digging Deeper into Text and Data Mining
    Haugen, Inga; Lener, Edward F.; Pannabecker, Virginia; Young, Philip (Virginia Tech, 2017-10)
    Text and data mining (TDM) approaches are increasingly used for research in a variety of disciplines to create, explore, and analyze large datasets. This presentation explores opportunities for library support for TDM, including expanding licensing permissions, clarifying legal aspects, identifying TDM sources and tools, developing expertise, and outreach.

    Library Support for Text and Data Mining: A Report for the University Libraries at Virginia Tech
    Young, Philip; Haugen, Inga; Lener, Edward F.; Pannabecker, Virginia; Brittle, Collin (Virginia Tech, 2017-07-28)
    This report examines how the University Libraries at Virginia Tech have supported text and data mining in the past, and how academic libraries in general are providing support for it. The report looks at licensing content for TDM as well as legal and technical aspects. The report concludes with recommendations for the University Libraries in order to support TDM for Virginia Tech researchers. Two appendices cover TDM interview questions and links to selected academic library guides to TDM, and selected references and websites are included.

    Mineral Chemistry of Heavy Minerals in the Old Hickory Deposit, Sussex and Dinwiddie Counties, Virginia
    Lener, Edward F. (Virginia Tech, 1997-12-11)
    The Old Hickory is the largest of a series of Pliocene (?) age heavy mineral sand deposits in Virginia and North Carolina. The high density of heavy minerals allows for selective concentration during transport and deposition. Under the right conditions, placers of considerable size can be formed. The elliptically shaped ore body of the Old Hickory Deposit extends in a North - South direction and is approximately 13 km (8 miles) long and up to 2.5 km (1.5 miles) wide, with an average thickness of 6.5 m (20 feet). The deposit lies along the Fall Zone, where a thin wedge of Cenozoic Coastal Plain sediments unconformably overlies the older rocks of the Piedmont. The principal minerals of economic interest found in the heavy mineral sands at the site are ilmenite (FeTiO₃), leucoxene (Fe2-xTi3+xO9+x/2) where x is less than or equal to 2, rutile (TiO₂), and zircon (ZrSiO₄). An important focus of this study is the alteration of ilmenite by leaching away of iron, which results in enrichment in titanium. Titanium metal is highly valued for its light weight and high strength. In terms of total economic value, however, the use of titanium dioxide pigments for paint, coated paper, and other products is far more important. As the value of the ore is heavily dependent on the titanium content, the weathering process is a matter of considerable interest to the mineral industry. Analysis of ilmenite grains using reflected light microscopy revealed a wide range of alteration textures. Quantitative analysis and mapping of trace elements showed altered areas with enrichment in Ti and depletion in Fe, Mn, Mg, and Cr. It is believed that the weathering process took place in a reducing environment prior to final deposition according to the reaction: Fe²⁺TiO₃ + 2H⁺ --> Fe²⁺ (aq) + TiO₂ + H₂O Reducing environments are found in water-logged soils such as floodplains and other low-lying areas. Repeated cycles of burial and exhumation during transport would have created conditions ideal for the removal of iron from the ilmenite.

    Open Education Forum 2024: Connecting the Opens
    McNabb, Kayla B.; Lener, Edward F.; Griffin, Julie; Guimont, Corinne; Pullen, Brandie; Walz, Anita R.; Orth, Donald J.; Surprenant, Aimée (Virginia Tech, 2024-03-18)
    University Libraries’ faculty, Corinne Guimont, Anita Walz, and Brandi Pullen will provide brief overviews of open publishing, open educational resources, and open data to provide some general information on the topics. Finally, presenters will discuss how aspects of open have impacted their career development as well as how they have incorporated open practices into their research and scholarship, and the audience will be invited to participate in the robust conversation.

    Raising the bar: An approach to reviewing and revising standards for professional achievement for library faculty
    Lener, Edward F.; Pencek, Bruce; Ariew, Susan (ACRL Publications, 2004-07)
    The committee revising the retention, promotion, and continued appointment policy in the Virginia Tech libraries took a broad view of its task in articulating its goal, gathering information from internal and external sources, allocating drafting responsibilities, and winning support. The committee's work revealed an unexpected need and led to an explicit affirmation of professional obligations of librarians to one another. Thus, adoption of the new policy and the principles it embodied became a lever for changes in the organizational culture.
