Economics of Networked Information Services Online Journals: Utility of ToCs vs. Fulltext George S. Porter Ed Sponsler Caltech Library System [email protected] Caltech • 285 Tenure-track faculty • 250 Principal investigators • 900 Undergraduates • 1100 Graduate students Caltech Library System • 55 FTE staff • 13 librarians • 5 information technologists • 49% of budget spent on information resources Why Use Click- Through Technology to Get Data on Ejournal Use? Never listen to what people say in response to a survey: Asking high-tech employees what will keep them in their jobs provides very different answers than the factors that actually drive retention.

  • Final-SPARC Paper Revised 2.Pdf (76.01Ko)
    A study of Canadian authorship in selected SPARC Alternative journals in the early years after their introduction By John Dupuis and Leila Fernandez Steacie Science and Engineering Library, York University, Toronto, Canada Abstract The Scholarly Publishing and Academic Resources Coalition (SPARC) is an initiative of the Association of Research Libraries. In 1998 SPARC introduced the Alternative Program working with partners to launch new journals to compete with existing high- priced titles in the STM field. Currently there are 11 titles in this program listed on the website (http://www.arl.org/sparc/partner/partnerlist.html), three of which are freely accessible. This study examines the earliest adopters, Organic Letters and Evolutionary Ecology Research to determine author satisfaction with these journals. Organic Letters although originally a SPARC Alternative journal is no longer listed under this Program. A survey of Canadian authors in these journals in the first five years since inception provides insight into the reasons why they chose to publish in these journals and has definite implications for librarians. The results of these surveys are discussed in the larger framework of existing scholarly communication models. Introduction: The Scholarly Publishing and Academic Resources Coalition is well-known in the scholarly communications arena through its various partnerships and programs, its advocacy initiatives and its promotion of open access publishing. Its early development and evolution has been traced by Mary Case in Igniting Change in Scholarly Communication: SPARC, Its Past, Present, and Future, which also provides an overview of the three main publisher partnership programs SPARC Alternative, SPARC Leading Edge and SPARC Scientific Communities.

Historically, the department has had several overlapping missions and goals- service teaching for science and engineering majors, professional training of chemistry majors and graduate students and ambitions for a nationally-recognized research program. CCB teaches ~3% of the student credit hours taught on main campus, and at one point had over 20 tenured and tenure track faculty and ~80 graduate students.

Thus, removal of nutrients is of great interest. Moreover, the removed nutrients can be recovered in forms amenable for agricultural reuse, which yields a sustainable supply of nonrenewable phosphorus that can be used to support global food production.

Zampese The complex [Cr(tpy)(O3SCF3)3] (tpy = 2,2’:6’,2’’-terpyridine) is readily made from [Cr(tpy)Cl3] and is a con- venient precursor to [Cr(tpy)2][PF6]3 and to [Cr(tpy)(4’-(4-tolyl)tpy)][PF6]3 and [Cr(tpy)(5,5’’-Me2tpy)][PF6]3 (4’-(4-tolyl)tpy = 4’-(4-tolyl)-2,2’:6’,2’’-terpyridine; 5,5’’-Me2tpy = 5,5’’-dimethyl-2,2’:6’,2’’-terpyridine); these are the first examples of heteroleptic bis(tpy) chromium(III) complexes. The single crystal structures of 2{[Cr(tpy)2][PF6]3}·5MeCN, [Cr(tpy)(4’-(4-tolyl)tpy)][PF6]3·3MeCN and [Cr(tpy)(5,5’’-Me2tpy)]- 3+ [PF6]3·3MeCN have been determined. Each cation contains the expected octahedral {Cr(tpy)2} unit; in all three structures, the need to accommodate three anions per cation and the solvent molecules pre- 2+ vents the formation of a grid-like array of cations that is typical of many lattices containing {M(tpy)2} Creative Commons Attribution 3.0 Unported Licence. motifs. Three reversible electrochemical processes are observed for [Cr(tpy)(4’-(4-tolyl)tpy)][PF6]3 and 3+ [Cr(tpy)(5,5’’-Me2tpy)][PF6]3, consistent with those documented for [Cr(tpy)2] . At pH 6.36, aqueous solu- 3 tions of [Cr(tpy)2][PF6]3 are stable for at least two months.
