Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Manufacturing Re-insourcing in the Textile Industry: A Case Study
No full textThis article aims to suggest to managers involved in re-engineering projects a method to assess the feasibility of manufacturing re-insourcing.
At first, an analysis of the textile sector is carried out.
Subsequently, a methodology is described, able to assess the feasibility of manufacturing re-insourcing. As a case study, a high production shop is then proposed and sized for the quick response requirements of a company producing young apparel lines on behalf of third parties. Finally,
an economic evaluation is carried out in order to assess the profitability of the re-insourcing strategy
Calculation of electric dipole hypershielding at the nuclei in diatomic molecules
No full textThe third-rank electric hypershielding at the nuclei of eight diatomic molecules and carbon dioxide has beenevaluated at the Hartree–Fock level of accuracy (i) by straightforward use of its definition within the Rayleigh–Schr€odinger perturbation theory and (ii) by a pointwise procedure for geometrical derivatives of electric dipole polarizability.The connection between these quantities is provided by the Hellmann–Feynman theorem. Extended ad hocbasis sets of big size and high flexibility have been employed in a numerical test of the theory to assess its practicality. Itis shown that constraints for rototranslational invariance and conditions provided by the virial theorem yield a naturalcriterion for near Hartree–Fock quality of nuclear electric hypershieldings computed by procedure (i)
