The Core Virtue of Christian Librarianship

Christian librarians should derive their professional ethics from methodical exegesis of the Bible. The New Testament\u27s most salient ethical statements center on love-for God, neighbor, and fellow believers. Each of these has significant implications for library practice. Identifying love as the core virtue of librarianship represents a radical departure from secular approaches to library ethics. While the biblical and secular models converge on some significant points, they are fundamentally opposite. Where the two reach similar conclusions, the biblical model proves to be more philosophically consistent. The Scriptures speak with enduring relevance to the issues facing librarians

Cones of Hilbert functions

We study the closed convex hull of various collections of Hilbert functions. Working over a standard graded polynomial ring with modules that are generated in degree zero, we describe the supporting hyperplanes and extreme rays for the cones generated by the Hilbert functions of all modules, all modules with bounded a-invariant, and all modules with bounded Castelnuovo-Mumford regularity. The first of these cones is infinite-dimensional and simplicial, the second is finite-dimensional but neither simplicial nor polyhedral, and the third is finite-dimensional and simplicial.Comment: 20 pages, 2 figure

Projective toric varieties as fine moduli spaces of quiver representations

This paper proves that every projective toric variety is the fine moduli space for stable representations of an appropriate bound quiver. To accomplish this, we study the quiver $Q$ with relations $R$ corresponding to the finite-dimensional algebra $\bigl(\bigoplus_{i=0}^{r} L_i \bigr)$ where $\mathcal{L} := (\mathscr{O}_X,L_1, ...c, L_r)$ is a list of line bundles on a projective toric variety $X$. The quiver $Q$ defines a smooth projective toric variety, called the multilinear series $|\mathcal{L}|$, and a map $X \to |\mathcal{L}|$. We provide necessary and sufficient conditions for the induced map to be a closed embedding. As a consequence, we obtain a new geometric quotient construction of projective toric varieties. Under slightly stronger hypotheses on $\mathcal{L}$, the closed embedding identifies $X$ with the fine moduli space of stable representations for the bound quiver $(Q,R)$.Comment: revised version: improved exposition, corrected typos and other minor change

A Philosophy Of Christian Librarianship

While a number of Christian librarians have explored the implications of the Christian world view for particular issues in library practice, few have attempted to develop a thoroughgoing philosophy of Christian librarians/zip. Those who have done so have generally failed to center their proposals around the Christian view of truth. The knowability, objectivity, unity, practicality, and spirituality of truth should impact the way librarians at Christian colleges carry out major library functions, including collection development, reference services, bibliographic instruction, research and publication, and management

Academic Libraries in Transition: Current Trends, Future Prospects

Academic libraries are in transition because of changes in the context of higher education. Changes in the world of information are even more radical: the displacement of paper, the primacy of the search engine, the emergence of the digital lifestyle, and innovative patterns of scholarly communication. Decreasing reliance on local collections is transforming the library as a physical destination.Traditional measures of library success have begun to be replaced. Given the superiority of other information professionals’ data management skills, the role of academic librarians will shift toward the enablement of learning.This environment of upheaval will pose both opportunities and challenges for academic librarians

Different approaches and responsibilities for investment sustainability in EU railway infrastructure: Four case studies

This paper describes the approach to investment in rail infrastructure in four different European countries (Great Britain, France, Germany, and the Netherlands) with a view to understanding whether and how these countries differ in their approach to the sustainability of investment in infrastructure. We compare and contrast different approaches to investment, such as: The direct role of government; The role of the economic regulator, where available; The influence of particular ownership agreements, such as the use of concessions for high-speed lines; Any differential treatment of different assets, and any differential treatment of different items of expenditure, such as maintenance, renewals, and enhancements; The role played by private capital (in infrastructure as separate from passenger and freight train operations); and The existence of a (more or less unlimited), either direct or indirect, state guarantee on debt issued to fund investment in network assets. In analysing the European case studies, the paper asks the following questions, which may differ across infrastructure categories (for instance track/signalling, stations, and high-speed lines): (i) What is the ownership structure of each IM? (ii) Who “sponsors” and specifies investment? (iii) Who is responsible for planning and approving investment? (iv) What are the ultimate funding sources of investment? (v) Who is responsible for delivering investment? (vi) What is the role of the independent economic and technical regulator (where availble) vis-à-vis the government? (vii) Is there any (direct or indirect) market mechanism, for instance as part of incentive regulation, that is mimicked when incentivising the monopoly provider of infrastructure to achieve a sustainable level of investment? The paper concludes with some policy considerations and recommendations based on the four case studies examined.railway; reform; investment in public transport
