The free oscillations models of Chile 2010 and 1960 events observed with the Grotta Gigante horizontal pendulums
No full textThe Grotta Gigante is located on the Trieste Carst close to the Adriatic Sea in Italy. It is the greatest cave in the world in terms of single volume cave and has a diameter of 100 m. In 1959 the Marussi horizontal pendulums were installed for the first time. They are very stable tiltmeters due to the type of installation
which uses the entire height of the cave (Marussi, 1959, Braitenberg et al., 2005). Though having been modernized and some maintenance having been applied, the instruments are perfectly controlled in their instrumental response during the 50 years of functioning. We have an absolute control on the correctness of the amplitudes by the tidal signal, which is observed very well on the instrument. At our knowledge it is
the only station that uses the same instruments in the same location and has observed three of the five greatest events ever measured: Cile 1960 (M=9.5), 2010 (M=8.8), and Sumatra 2004 (M=9.3) (Bolt and Marussi, 1962; Bozzi Zadro and Marussi, 1967; Braitenberg and Zadro, 2007). We analyze the gravest modes of the free oscillations as 0S2, 0T2, 1S2 and determine frequencies and amplitudes of the modes for the events of Cile and Sumatra. Two minor events are added, as Cile 2007 and Sumatra 2005. For the spectral analysis we use the method described in Braitenberg and Zadro (2007), We find a few spectral
amplitudes that are common to the different spectra and are intermediate to the theoretical free oscillation frequencies. We determine the Q values for the low degree free oscillation frequencies. At last we seek a direct comparison of the oscillation amplitudes for the different events. The observation of the 1960 event was made on photographic paper, the recent events are made with a digital system, which has some consequences on the resolution of the first part of the record.

A protocol of intermittent exercise (shuttle runs) to train young basketball players
No full textThe purpose of this study was to set up a protocol of intermittent exercise to train young basketball players. Twenty-one players were asked to complete (a) an incremental test to determine maximal oxygen uptake (VO2max), the speed at the ventilatory threshold (vthr) and the energy cost of "linear" running (Cr) and (b) an intermittent test composed of 10 shuttle runs of 10-second duration and 30-seconds of recovery (total duration: about 6 minutes). The exercise intensity (the running speed, vi) was set at 130% of vthr. During the intermittent tests, oxygen uptake (VO2) and blood lactate concentration (Lab) were measured. The average pretraining VO2 calculated for a single bout (131 ± 9 ml · min(-1) kg(-1)) was about 2.4 times greater than the subjects' measured VO2max (54.7 ± 4.6 ml · min(-1) · kg(-1)). The net energy cost of running (9.2 ± 0.9 J · m(-1) · kg(-1)) was about 2.4 times higher than that measured at constant "linear" speed (3.9 ± 0.3 J · m(-1) · kg(-1)). The intermittent test was repeated after 7 weeks of training: 9 subjects (control group [CG]) maintained their traditional training schedule, whereas for 12 subjects (experimental group [EG]) part of the training was replaced by intermittent exercise (the same shuttle test as described above). After training, the VO2 measured during the intermittent test was significantly reduced (p < 0.05) in both groups (-10.9% in EG and - 4.6 in CG %), whereas Lab decreased significantly only for EG (-31.5%). These data suggest that this training protocol is effective in reducing lactate accumulation in young basketball player

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
"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.
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
