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
Historical Fragments Preserved by the Indirect Tradition: Some Evaluations from Theory to Practice
No full textThe interpretation of Arist. Ath. Pol. fr. 3 constitutes an appropriate demonstration from a methodological viewpoint. During the last 40 years, the category of the fragment has become something ‘other’ than the past. The highly hypothetical level of all that concerns it has been taken into account and consequently demands to be addressed not only in commentaries or in theoretical studies. The time has come to apply this methodological attainment also, and especially, to historical reconstruction when it uses fragments as a source
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
A note on Hadamard fractional differential equations with varying coefficients and their applications in probability
No full textIn this paper, we show several connections between special functions arising from generalized Conway-Maxwell-Poisson (COM-Poisson) type statistical distributions and integro-differential equations with varying coefficients involving Hadamard-type operators. New analytical results are obtained, showing the particular role of Hadamard-type derivatives in connection with a recently introduced generalization of the Le Roy function. We are also able to prove a general connection between fractional hyper-Bessel-type equations involving Hadamard operators and Le Roy functions
A SEPARATE COLLECTION CENTRE SEEN AS A “REVERSE SUPERMARKET” IN AN URBAN MINING PERSPECTIVE
No full textThe separate collection centres (SCC), where citizens can deliver recyclable fractions of MSW, play an important role in a separate collection system. They can be considered a sort of “reverse supermarket”, where people can deliver their recyclables in order to obtain a reduction on
the tax to pay or shopping vouchers. This latter is the case of Baronissi, a town of around 17,000 inhabitants in the Province of Salerno, in the Campania region of Italy. The principal aim of the study
was to investigate by means of a survey the relationship between citizens
and the separate collection program, with particular emphasis on the role played by the SCC. The separate collection system was positively evaluated by 95.8% of the sample, while 99.2% expressed a good or very
good evaluation of the quality of the service inside the separate collection centre. The opinion that going to the SCC is more environmentally sound was the most successful among the respondents
Cosmetic possibilities and problems in eyelid neurofibromas
No full textNeurofibromatosis type 1 (NF1) is an inherited systemic disease with frequent ocular involvement. A typical alteration observed in NF1 is the eyelid plexiform neurofibroma, often associated with facial homolateral hypertrophy. In such cases, surgical cosmetic results are rather unsatisfactory, since plexiform neurofibromas classically show a non-capsulated mass, with a marked tendency to local recurrence. The techniques for a cosmetic attempt are discussed on the basis of a personal series of eyelid reconstructions in NF1. The results can be considered satisfactory in some cases, when the orbital shape is preserved and the eyelid structure has not been excessively altered by the neurofibroma; in all other cases, the cosmetic outcome is inferior to the patient's and parents' expectations. The serious problem of recurrence is however a limitation to cosmetic surgery in eyelid neurofibromas
Treatment of macroglossia in Beckwith-Wiedemann syndrome
No full textA case of macroglossia caused by Beckwith Wiedemann syndrome is reported. Beckwith-Wiedemann Syndrome is an overgrowth disorder characterized by a constellation of congenital anomalies. The most common manifestations are omphalocele, macroglossia, gigantism, and visceromegaly. When the tongue reaches a huge dimension, clinical symptoms are represented by dysphagia, alterations in speech, difficulty in chewing, obstruction of the upper airways, and psychologic consequences derived from the patient's physical appearance. The authors describe the surgical strategy performed in the reported case
