Complexes of technetium(IV) and (III) with tertiary phosphines.
No full textTrans-TcX4L2 and mer-TcX3L3 (X = Cl, Br; L = PMe2Ph, PEt2Ph, PPh3) were prepd. from NH4TcO4, HX, and L in EtOH and characterized by far-ir and PMR spectra. TcCl3(PMe2Ph)3 refluxed in CCl4 gave TcCl4(PMe2Ph)2 and redn. of the latter with NaBH4 gave the former. Magnetic susceptibility and PMR results for mer-TcCl3(PMe2Ph)3 were compared with those for analogous d4 complexes
Co-production and nudging: The enabling role of ICT
No full textCo-production and nudging reflect the new paths taken by governments in the digital transformation age. Both are behaviour-based tools of public action. Both are premised on the idea that citizen engagement in public services is essential for problem solving. Thus far, however, these topics of debate have been addressed in isolation. The aim of this explorative paper is twofold: to come to an overall assessment about the potential of co-production and nudging, analysing the links between them, and the role that ICT plays in improving citizen behaviours. Draw-ing on a service lens, the paper makes the case that co-production and nudging can be combined to support citizens in their ‘service user journey’. This tentative exercise is a conceptual one, but hopefully one that broadens the understanding of citizens’ participation mediated by digital technologies. In essence, the joint adop-tion of co-production and nudging could help design and deliver services that bet-ter meet citizen needs
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Shared services : exploring the new frontier
No full textThe big squeeze on public spending and the need to get Italy’s small local councils fully on board the e-government agenda is forcing both the public and the private sector to think of new ways to source and deliver public services. The sharing of services is one solution that goes beyond the traditional insourcing/outsourcing model to cast the SSO in the primary role of Information and Communication Technology (ICT) provider. The paper illustrates a case study in which, after a few “false starts”, an Italian company made the positive transition from PPP to public SSO, building relations of trust and a flexible offer that met the councils’ need to retain their individuality. The general reflection that follows has the aim of further informing the debate on the redesign of organizational activities through service management, and supports the continuity of the basic organizational logics that inform the practices of the public SSO
