Outsourcing and externalisation: current practice in UK libraries, museums and archives

A study, funded by Resource: The Council for Museums, Archives and Libraries, was undertaken in 2000-2001 to give an up-to-date view of the current experience of outsourcing and externalisation in libraries, museums and archives. Case studies of purchasers recognised as pioneers in the field, and of providers, were undertaken, and results validated by two focus groups. Outsourcing, particularly under the impetus of Best Value, was found to be relatively widespread and sophisticated in the public library and special library sectors. Thinking and practice in academic libraries lag behind. Museums and archives show some implementation, particularly under the influence of Best Value

A study of outsourcing and externalisation by libraries with additional reference to the museums and archives domains

This study provides an up-to-date view of the current experience of outsourcing and externalisation in the library and information domain, particularly higher education, public and special libraries, and its potential, together with an assessment of the effects of the external economic, political and technical pressures on service providers leading to change. Information has also been gathered from, and parallels drawn with, the other domains within Resource's remit, museums and archives, giving some indication of the context of, and scope for, cross-domain working. The practical issues arising have been documented, and a decision matrix, recommended for judging the potential within an organisation for outsourcing, produced. This study has also undertaken an assessment of potential suppliers and agents in the market place: their capabilities, readiness, interests and future plans to meet increasing demands for outsourcing

Mechanisms Affecting Emission in Rare-Earth-Activated Phosphors

The relatively poor efficiency of phosphor materials in cathodoluminescence with low accelerating voltages is a major concern in the design of field emission flat panel displays operated below 5 kV. The authors research on rare-earth-activated phosphors indicates that mechanisms involving interactions of excited activators have a significant impact on phosphor efficiency. Persistence measurements in photoluminescence (PL) and cathodoluminescence (CL) show significant deviations from the sequential relaxation model. This model assumes that higher excited manifolds in an activator de-excite primarily by phonon-mediated sequential relaxation to lower energy manifolds in the same activator ion. In addition to sequential relaxation, there appears to be strong coupling between activators, which results in energy transfer interactions. Some of these interactions negatively impact phosphor efficiency by nonradiatively de-exciting activators. Increasing activator concentration enhances these interactions. The net effect is a significant degradation in phosphor efficiency at useful activator concentrations, which is exaggerated when low-energy electron beams are used to excite the emission

Radiocarbon Dating Uncertainty and the Reliability of the PEWMA Method of Time-Series Analysis for Research on Long-Term Human-Environment Interaction

Statistical time-series analysis has the potential to improve our understanding of human-environment interaction in deep time. However, radiocarbon dating—the most common chronometric technique in archaeological and palaeoenvironmental research—creates challenges for established statistical methods. The methods assume that observations in a time-series are precisely dated, but this assumption is often violated when calibrated radiocarbon dates are used because they usually have highly irregular uncertainties. As a result, it is unclear whether the methods can be reliably used on radiocarbon-dated time-series. With this in mind, we conducted a large simulation study to investigate the impact of chronological uncertainty on a potentially useful time-series method. The method is a type of regression involving a prediction algorithm called the Poisson Exponentially Weighted Moving Average (PEMWA). It is designed for use with count time-series data, which makes it applicable to a wide range of questions about human-environment interaction in deep time. Our simulations suggest that the PEWMA method can often correctly identify relationships between time-series despite chronological uncertainty. When two time-series are correlated with a coefficient of 0.25, the method is able to identify that relationship correctly 20–30% of the time, providing the time-series contain low noise levels. With correlations of around 0.5, it is capable of correctly identifying correlations despite chronological uncertainty more than 90% of the time. While further testing is desirable, these findings indicate that the method can be used to test hypotheses about long-term human-environment interaction with a reasonable degree of confidence

Separating and Collapsing Electoral Control Types

[HHM20] discovered, for 7 pairs (C,D) of seemingly distinct standard electoral control types, that C and D are identical: For each input I and each election system, I is a Yes instance of both C and D, or of neither. Surprisingly this had gone undetected, even as the field was score-carding how many std. control types election systems were resistant to; various "different" cells on such score cards were, unknowingly, duplicate effort on the same issue. This naturally raises the worry that other pairs of control types are also identical, and so work still is being needlessly duplicated. We determine, for all std. control types, which pairs are, for elections whose votes are linear orderings of the candidates, always identical. We show that no identical control pairs exist beyond the known 7. We for 3 central election systems determine which control pairs are identical ("collapse") with respect to those systems, and we explore containment/incomparability relationships between control pairs. For approval voting, which has a different "type" for its votes, [HHM20]'s 7 collapses still hold. But we find 14 additional collapses that hold for approval voting but not for some election systems whose votes are linear orderings. We find 1 additional collapse for veto and none for plurality. We prove that each of the 3 election systems mentioned have no collapses other than those inherited from [HHM20] or added here. But we show many new containment relationships that hold between some separating control pairs, and for each separating pair of std. control types classify its separation in terms of containment (always, and strict on some inputs) or incomparability. Our work, for the general case and these 3 important election systems, clarifies the landscape of the 44 std. control types, for each pair collapsing or separating them, and also providing finer-grained information on the separations.Comment: The arXiv.org metadata abstract is an abridged version; please see the paper for the full abstrac
