Social networks in R&D program evaluation

This paper introduces the social network methodology as a tool for evaluating important aspects of research and development (R&D) programs. It uses two detailed examples to illustrate the application of network concepts in program appraisal. By studying relationships, exchanges, network location and status, network structure and evolution, and participant characteristics and roles in the network, this approach provides a lens to important aspects of the longer-lasting, more sustainable contributions of public policy in affecting organisational capabilities to innovate. A key challenge currently is the integration of social network analysis with causal empirical models and more traditional economic approaches geared to assessing the outputs and impacts of R&D.

Cycle avoiding trajectories,strategic agendas,and the duality of memory and foresight: An informal exposition

This paper considers the notion of cycle avoiding trajectories in majority voting tournaments and shows that they underlie and guide several apparently disparate voting processes. The set of alternatives that are maximal with respect to such trajectories constitutes a new solution set of considerable significance. It may be dubbed the Banks set, in recognition of the important paper by Banks (1985) that first made use of this set. The purpose of this paper is to informally demonstrate that the Banks set is a solution set of broad relevance for understanding group decision making in both cooperative and non-cooperative settings and under both sincere and sophisticated voting. In addition, we show how sincere and sophisticated voting processes can be viewed as mirror images of one another — embodying respectively, “dmemory” and “foresight.” We also show how to develop the idea of a “sophisticated agenda,” one in which the choice of what alternatives to propose is itself a matter of strategic calculation.     

Extension of the color suite available for chemical enhancement of fingerprints in blood

The use of ortho- and para-phenylenediamine (OPD & PPD respectively) for the enhancement of fingerprints in blood has been investigated. Optimal pH conditions and H2O2 concentrations have been determined using UV/Vis spectroscopy. Both OPD and PPD are effective and less hazardous alternatives to the presently used 3,3'-diaminobenzidine (DAB) for the development of blood fingerprints, especially on porous surfaces. The orange color of OPD and the purple color of PPD offer alternative colors to the brown color of DAB and the light green color of ABTS for standing out against particular backgrounds. Both OPD and PPD can be used after ninhydrin treatment, but the reverse is not the case.     

Liberal Republicanism

In this article I defend a broadly Rawlsian interpretation of citizenship which combines both liberal and republican themes to provide an account of citizenship which is more appropriate for modern democracies than alternative interpretations, such as that offered by communitarian critics of political liberalism. Liberal republicanism, I argue, gives a convincing interpretation of the nature and value of citizenship and provides the basis for a radical political agenda.     

An ideal material for the preparation of known toolmark test impressions

Traditionally, toolmark test exemplars are produced by applying a tool's working surface to a piece of soft metal such as lead. Soft, pliable metals are primarily used for this purpose because they will replicate the microscopic grooves present on a tool's working surface without damaging the tool. In this paper the authors present an alternative material for the preparation of test toolmarks. Jewelry modeling or carving waxes are utilized in this study. These waxes are designed for the jewelry modeling industry to create very fine, highly detailed wax models of jewelry pieces that will be cast in various metals utilizing the lost wax casting method. Jeweler's waxes have been found to be ideal for preparing test toolmarks from exemplar tools. The test tool's working surface is applied to a piece of the appropriate wax in a manner consistent with the tool's design. The replicas obtained are exact, highly detailed, 1:1, negative impressions of the exemplar tools working surface, have a long shelf-life, and are suitable for use in toolmark examination and comparison cases.
