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
FIRE-MAKING USING A STONE `STRIKE-A-LIGHT' IN THE SOA BASIN OF FLORES, INDONESIA
Full text linkDuring recent archaeological fieldwork on the island of Flores in eastern Indonesia, the author observed a firemaking technique involving the use of a stone `strike-alight' (see Skertchly 1879). The strike-a-light used was a chalcedony flake scavenged from a prehistoric site; hence the fire-making technique has archaeological and in particular, taphonomic, significance
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
Prehistoric Human Migration in Indonesia: A Rock Art Perspective
No full textThis doctoral research focuses on rock art dating in Indonesia. A novel approach has been developed--laser ablation uranium-series dating--enabling the rapid and accurate dating of calcium carbonate deposits found in association with rock art in limestone karst environments (Oktaviana et al., 2024a). This approach will revolutionize rock art dating worldwide. To demonstrate its efficacy, we have redated the oldest known narrative composition so far discovered, a rock art depiction of a hunting scene from Leang Bulu' Sipong 4 in the Maros-Pangkep karsts of southwestern Sulawesi. At a minimum of 48,000 years old, this art it is at least 4,040 years older than previously thought (Aubert et al., 2019; Oktaviana et al., 2024a). Laser ablation uranium-series dating was also used to date a newly discovered narrative scene in Maros-Pangkep. The results indicate that the origin of visual storytelling in humans goes back at least 51,200 years (Oktaviana et al., 2024a). This, together with other early rock art narrative scenes from this region of South Sulawesi, (Aubert et al., 2014, 2019; Brumm et al., 2021), suggest that the representation of composed scenes in early Palaeolithic rock art was more common than previously thought, providing a unique and intimate window into the minds of modern humans at that time. This paper has been accepted for publication in the high-impact scientific journal Nature.
Rock art was also discovered and dated in other areas of Sulawesi (Oktaviana et al., 2024b; 2024c). In the Bone karst region of southwestern Sulawesi, a spectacular rock art site is described in detail. The site was not subject to our novel dating approach owing to the absence calcium carbonate materials covering some of the art. However, the depicted subject matter and style of execution suggest a similar Pleistocene origin, but an earlier age cannot be completely excluded (Oktaviana et al., 2024c). A series of Pleistocene human hand stencils were also dated from several sites in southeastern Sulawesi, indicating that Palaeolithic rock art is not limited to the southwestern peninsula of this Indonesian island. Notably, a human hand stencil from Muna island (a satellite island of Sulawesi) is dated to at least 62,700 years ago (Oktaviana et al., 2024b). This age firmly places modern humans on the northern island chains of Indonesia, one of two major possible migration routes proposed for the colonization of Sahul (Australia and New Guinea joined at lower sea levels) (Birdsell, 1977; Kealy et al., 2017, 2018; Norman et al., 2018; Bird et al., 2019), and matches early dates for our species arrival in Australia (Clarkson et al., 2017). Moreover, it suggests that the first humans to reach Sahul were making rock art, with obvious and important implications for the likely antiquity of the earliest rock art of Australia and Papua.
This PhD research shows that Pleistocene rock art can be used to trace the migrations of early modern humans in Indonesia. The Indonesian archipelago is also host to vast collections of more recent rock art. Some of this art is attributed to the arrival of the Austronesian culture in the region. The Austronesian Painting Tradition (APT) is, however, poorly dated. The laser ablation uranium-series dating approach was used to provide the largest collections of dates for APT rock art ever produced (Oktaviana et al., 2024b; 2024d). The dating shows that most of this art is Holocene in age and confirms the rapid expansion of this culture with essentially similar arrival ages for Sulawesi and Papua some ~4,000 years ago (Oktaviana et al., 2024b; 2024d). However, some of the dated motifs are clearly older and their ages and possible attribution to the APT (e.g. Arifin & Delanghe, 2004; Gonthier et al., 2013; Leihitu & Permana, 2019; Permana, 2019) suggest that these older paintings could have influenced the development of the APT and that this tradition could have originated in this region instead of the Austronesian home world of Taiwan or the northern Philippines (Bulbeck, 2008; O'Connor et al., 2015; Hoerman, 2016; Jalandoni, 2021). Finally, recent ages for some motifs suggest that this tradition continued to evolved and that rock paintings were still being produced a few hundred years ago (Oktaviana et al., 2024b; 2024d).Thesis (PhD Doctorate)Doctor of PhilosophySchool of Hum, Lang & Soc ScArts, Education and Law GroupFull Tex
