The ionic conductivity of LiBOB-doped electrolytes containing two silyl solvents, bis[2-(2-methoxyethoxy)ethoxy] dimethylsilane, 1, and [2-(2-methoxyethoxy)ethoxy] trimethylsilane,2, was measured from 10 C to 50 C using AC impedance spectroscopy to assess their potential use in commercial Li-ion cells. The effects of salt concentration, solvent composition, and temperature on the conductivity of the electrolytes are reported. In addition, conductivity data were fit using the Vogel-Tamman-Fulcher (VTF) equation to obtain the parameters s0, T0, and Ea, which correspond closely to conductivity and viscosity. All the electrolytes produced conductivities above the 1.0 mS cm1 threshold required for commercial application. The 1:1 (vl) solvent composition possesses the highest conductivity, with the optimal 0.8 M salt-loading yielding the highest s25 at 1.99 ± 0.02 mS cm1.

This chapter details several activities undertaken by the Grinnell College Libraries to increase student engagement. These activities include student-curated exhibits, events at which students read their own creative and scholarly works for a community audience, a peer mentoring program, ways to engage students in making decisions about how the library is run, and activities that create a feeling of community for diverse students and increase students’ awareness of diverse cultures. Research has shown that students who are more engaged are more likely to succeed in college, and the Grinnell College Libraries believe that their programs to increase student engagement are contributing to the success of Grinnell students.

Technical services departments in academic libraries have long struggled to communicate effectively with other library departments, particularly public services departments. As academic libraries acquire large numbers of digital resources, technical services departments are increasingly responsible for providing current information about those resources to public services staff. The authors of this paper describe the process of creating, testing, and implementing LibGuides (proprietary software for building library portals and facilitating information sharing in libraries) as a new way of communicating much-needed information between technical services and public services staff at Miami University Libraries.

This data set is designed for testing the performance of optical character recognition (OCR) algorithms on text in scanned historical map images. Thirty maps from the nineteenth and early twentieth centuries (1866–1927) were chosen from nine atlases in the David Rumsey Map Collection. Most maps are of individual states, though some are regional and one is of the entire U.S.; most are manually typeset, with occasional handwritten text. Each place name and many other textual items are annotated with the baseline, bounds, character heights, and ground truth text transcriptions. Several maps also feature USGS GNIS Feature ID tags for labeled items. Java code for processing is provided with the text-based XML annotations, alongside the original, compressed MrSID images and uncompressed TIFF images. We gratefully acknowledge the David Rumsey Map Collection as the source of the map images, which come with the following notice: "Images copyright 2000 by Cartography Associates.

This data set is designed for testing the performance of optical character recognition algorithms on text in scanned historical map images. Thirty maps from the nineteenth and early twentieth centuries were chosen from the David Rumsey Map Collection (http://davidrumsey.com). Most maps are of individual states, though some are regional and one is of the entire U.S.; most feature little handwritten text. The original MrSid files are converted into uncompressed TIFF images for a manual annotation, stored in XML format. The authors gratefully acknowledge the David Rumsey Map Collection as the source of the map images, which come with the following notice: Images copyright © 2000 by Cartography Associates.

Ciota, Rebecca.
Many institutions digitize their physical collections. Unfortunately, once these items are digitized, they reside in a repository and act merely as digital representations of their physical counterparts. I discuss how libraries can make greater use of their homegrown electronic resources through collaborations between scholars, students, and the general community.

While undertaking their graduate studies, many library and information science (LIS) students seek pre-professional graduate assistantships. These assistantships can serve as excellent opportunities to complement student’s education and influence their future careers by providing them with relevant on-the-job education and skills. Graduate assistantships are a crucial to LIS education in helping new LIS professionals develop skills and experiences needed to attain gainful, professional employment.

Sister taxa often differ phenotypically, yet we generally do not know whether trait divergence reflects adaptation to spatially-varying selection. In a reciprocal transplant experiment, we ask whether selection favors the native phenotype in two parapatric subspecies of Clarkia xantiana (Onagraceae), an annual plant endemic to California. We quantified phenotypic selection in each of the exclusive ranges and the contact zone in two years with contrasting climates. We predicted that in the arid, pollinator-scarce eastern region of the distribution, phenotypes of the native subspecies (parviflora) have an advantage: small leaves, slow leaf growth, accelerated flowering, and diminutive flowers. In the wetter, pollinator-rich, western range of subspecies xantiana, we expected selection for the opposite phenotypes. We predicted that temporal variation in selection would favor xantiana¬-like traits during the first wet El Niño year and parviflora-like traits in the second dry La Niña year. For subspecies xantiana, selection generally favored native phenotypes in the native garden. However, for parviflora, selection sometimes favored non-native trait values. We found little evidence for pollinator-mediated selection, subspecies differences in pollen limitation to reproduction, or temporal variation in selection. Phenotypic differentiation appears to reflect divergent selection in xantiana, but not parviflora.

Ferguson, William D.
A simple two-sector effort-regulation model, which assumes that the cost of job loss responds to labor's bargaining power and which acknowledges influences of institutional change, import penetration and shifting employment, can account for the declining real wages for non-supervisory workers in goods sector industries in the 1980s.

The operation of labor markets differs fundamentally from that of other markets because the commodity traded, hours of labor time, cannot be separated from human beings. Efficiency wage models, and effort-regulation (or shirking) models in particular address the issue of individual motivation by explicitly considering the influence of the wage on the worker's decision concerning the level of effort exerted. This paper offers a theoretical argument that a cost-based conception of union bargaining power is compatible with an effort-regulation/contested exchange framework.

This paper investigates causes of the dramatic increase in the wage-productivity gap—the divergence between the growth rates of aggregate productivity and real wages - in the post-1981 period. Using a two-step estimation procedure which incorporates three-digit industry wage regression coefficients into an aggregate wage growth identity equation, it finds that employment decline within unionized industries explains 18% of the post-1981 increase in the gap and that declining union ability to raise wages may explain as much as another 25%. Imports, on the other hand, do not appear to explain the gap independently of employment effects.

Ferguson, William D.
The terms of market exchange can, under certain conditions, even in competitive markets, reflect underlying power relationships. Bilateral market power exists in employment relationships whenever both workers and employers benefit from maintaining their association: whenever the value of the employment relationship exceeds the value of the next best alternative for both parties simultaneously. This paper develops a widely applicable model of bilateral market power in employment relationships along with some of its implications.
