Full text linkDifferential nuptiality and fertility in the Länder of the Austrian Empire (1828–1865)
No full textWe examine different aspects of nuptiality and fertility in the La ̈nder of the Austrian Empire using the
Tafeln zur Statistik der O ̈sterreichischen Monarchie (Statistical Tables of the Austrian Monarchy). This
source, published from 1829 to 1871, contains data on population and natural movement. After
discussing its quality, we study marriage and birth rates, and also age at wedding, illegitimacy ratio,
and marital fertility. We find meaningful differences between the regions of Empire: low and late
nuptiality in some central La ̈nder, which generally have consequences for birth rates. The frequency
of illegitimacy and marital fertility rates are also examined for the 15 La ̈nder
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
An unexpected demographic regime: The western necropolis of the Greek colony of Himera (Sicily, Italy) (550-409 BCE)
No full textWe present the results of a paleodemographic assessment of 2865 graves excavated in the western necropolis of the ancient Greek colony of Himera in Sicily. Himera provides an outstanding opportunity to understand the demographic dynamics of Ancient Sicily as it was abandoned and never repopulated, thus offering a completely intact record. Not only has a remarkably large sample been collected and is currently under study, but historical
sources allow to precisely date the years in which the city’s necropolises were used. Children under the age of 5 were typically buried in pots, meaning that the number of children who died at ages 0 and 1–4 can be reliably estimated. Such data on child death is very rare in paleodemographic studies. Thanks to these exceptional characteristics, together with the application of demographic methods already employed in previous studies (Barbiera et al., 2021) and a comparison of our results with other contemporary Greek necropolises, we can discern a plausible mortality regime for Himera. Our analyses reveal that in the western necropolis of Himera (mid-6th to late 5th century BC) the mortality of children and young people was relatively low, and likely compensated by a more pronounced mortality of adults. Life expectancy at birth was plausibly between 25 and 30 years of age. These fndings are further supported by data from the Greek cities of Metaponto and Akraiphia, as well as preliminary results for the eastern necropolis of Himera (late-7th to late 6th century BC)
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
