The rock-cut chamber tomb D in Pella
No full textNo abstract The rock-cut chamber tomb D was discovered in the area east of ancient Pella, in October 1977, during the construction of an enormous water pipe from Aravissos to Thessaloniki. According to the known typology of the subterranean tombs, it has an antechamber and chamber, both in the same direction, from N-S, and a long «dromos» in front of a simple, without façade, entrance. Inside the tomb, there were found klinai, cut into the rock, two in the antechamber and three in the chamber. Iron nails and, in two cases, pie ces of wood, proove that the bodies were laid on wooden biers. Cremated bone was gathered in the northern corner of the two klinai of the antechamber. The placement of the offerings beside the head and the feet of the dead, indicates certain identity in burial customs to those observed in other parts of Greece as in Véroia, Corinth, Pylos, etc. The grave goods consisted mainly of ceramic vessels (lamps, unguentaria, amphoras, pyxides, a plate, a megarian bowl, etc.) metal objects (gold leaves, lead pyxides) and various other objects. The offerings can be dated in the 2nd century B.C., namely after the middle of the century, and indicate that the city of Pella though in a poor and deteriorating condition, continued to live after the Roman destruction of 168 B.C

MeSH term explosion and author rank improve expert recommendations
Get PDFInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
Get PDFBoth 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.
