Nacerdes melanura
No full textNacerdes melanura (Linnaeus 1758) (Fig. 1) On the 31 th of May 2012 twelve specimens of Nacerdes melanura (Linnaeus, 1758) were collected from buildings in different streets in Nesher and brought to Tel-Aviv University by U. Shalom (Ministry of Environmental Protection). Mr. Shalom reported that N. melanura were infesting some houses in the area for the last 5 years or so. Adults were seen from May to July inside and around the buildings, mainly during the morning hours. Nesher is a small town on the northeastern slopes of the Carmel Ridge, close to Haifa and its harbor. Nacerdes melanura is also known by its common name "the Wharf borer". It is a well known wood boring species with a preference for wet and decaying wood (ISU Extension 2005). Larvae often inhabit wet timber along rivers and harbors and therefore it is considered a major pest in docks and stored wooden objects in warehouses (Unger et al. 2011). It is most probable that this species was introduced to Israel through the harbor of Haifa. On the 16 th of May 2013 the first author (OR) collected a single specimen in a plant nursery in Kefar 'Azar in the central coastal plain of Israel, 6 km East of Tel-Aviv. This is the first record from central Israel and an expansion of its distribution to other parts of the country. We now consider N. melanura as an established new invasive pest species in Israel.

Xanthochroina auberti
No full textXanthochroina auberti (Abeille de Perrin 1876) (Fig. 2) On the 8 th of September 2011 the authors placed a light trap (mercury and UV light) at the edge of a small pine tree forest near the settlement of Nirit. A single individual of Xanthochroina auberti was collected. Based on this record, the authors searched through the unidentified material in the insect collection of the national collections of natural history of the Tel-Aviv University (TAUI) and discovered additional specimens from a wide range of habitats in Israel. This species was already known from Croatia, Cyprus, France, Greece, Hungary, Italy, Lebanon, Spain, Turkey (Švihla 2011) and Morocco (Arahou 2008). Colored habitus photos have been published from Spain (Dieguez Fernandez 2010; Lencina et al. 2008), Hungary (Merkl et al. 2010) and France (Ponel 2011). Despite its relatively broad distribution it is seldom collected and its biology is not yet fully understood. Adults can be found in cracks of Pinus halepensis ( Abeille de Perrin 1876; Ponel et al. 2011) under the foliage of Quercus ilex (Arahou 2008) or netting from Quercus (Merkl et al. 2010). Ponel (1993) suggested that it is probably a predator of wood boring beetles. However, the majority of records are from light traps. Since Israel is on the edge of its distributional area and the oldest record from Israel was from 1998 it is not clear if this species is a newly introduced species or a local one that was simply previously unnoticed.

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
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
