Geoarchaeology of Magdala harbour and Tel Akko (Israel)
Full text linkWith the support of the MISTRALS-ENVIMED-GEOSISRAEL program and A*MIDEX GEOMED project, we have been able to reconstruct the palaeo-environmental evolution of two ancient harbours in Israel. Harbour geoarchaeology was mainly developed in Israel by the late Avner Raban, founding member of the RIMS multidisciplinary research unit in 1972 at Haifa University. Since these pionneering years, a series of geoarchaeological projects have focused on different ancient harbours, mainly at Caesarea, Dor, and Atlit. Paradoxically, landscape evolution of the major harbour sites of Magdala and Tel Akko have been neglected until two comprehensive multidisciplinary archaeological projects were recently started.
Recent excavations undertaken in the ancient city of Magdala, located on the western shore of the Sea of Galilee, have unearthed a harbour structure extending for more than 100 m, dating from the late Hellenistic (167-63 BC) to the middle Roman (70-270 AD) periods, with well-preserved quays and mooring stones. An integrated (geomorphological, sedimentological, micropalaeontological and archaeological) study of the sedimentary succession buried beneath the ancient harbour area reveals the harbour’s main evolutionary stages, shedding new light on the natural versus anthropogenic controls on sedimentation. Three sedimentary sequences reflect the recent palaeoenvironmental evolution of Magdala. These include: 1) a pre-harbour foundation sequence; 2) a harbour sequence from the 3rd-2nd centuries BC to the first half of the 1st century AD. The substantial increase of ostracod species (Pseudocandona albicans) preferring calm waters and fine-grained facies point to the establishment of a protected, shallow and organic-rich setting. The increase in sodium and potassium concentrations is accompanied by the sudden appearance of Heterocypris salina, a brackish-tolerant species, and by the dominance of noded valves of Cyprideis torosa ; and 3) a harbour abandonment sequence dated ca. 270-350 years AD.
Archaeological excavations at Tel Akko, east of the present city, revealed imported artifacts and evidence for maritime trade from the Middle Bronze Age (2200–1500 years BC) onwards. The findings strongly indicated that a harbour had been developed on this site even though its exact location and associated facilities were still to be determined. Sedimentological and paleontological analyses together with 14C dating of cores provide new palaeo-environmental information allowing for the reconstruction of shoreline changes over the last 4000 years. Firstly, we propose that the southern face of the tell constituted the harbor environment,with lagoonal-marine characteristics until ca. 2800 years BP; and that the site was protected by a natural rocky breakwater and a spit which were eventually silted up and transformed into a continental marsh. This environment might have been used as a harbour by inhabitants before the archaic period. Secondly, it seems that the west side of the tell was lined by a sandy coast that had prograded offering an open anchorage until the Persian period. These results must be cross-validated by future archaeological excavations aimed at more accurately locating the ancient harbour structures.

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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
