Hochstetter's Survey of the Pink and White Terraces: the Final Iteration
No full textIn the June 2018 edition of Surveying+Spatial journal, I reported on Ferdinand von Hochstetter’s (1829−1884) 1859 survey of the Pink and White Terraces. This article reports new research findings on the survey, completing our study into the Terrace locations. Hochstetter remains the only terrestrial survey of this lost Eighth Wonder of the World: providing the only primary location evidence.
We first summarise the six survey methods Hochstetter may have employed. Next, we report primary evidence of his second Lake Rotomahana observation station on Puai Island. Our evidence-based lakes’ altimetry is updated. We reconcile the incorrect coordinates on August Petermann's (1822−1878) 1864 Rotomahana map and reintegrate it with Hochstetter's mapping. His method-of-squares map scale is calculated from his paper stock. Our final, survey iteration/replication uses all 14 surviving survey landmarks. Lastly, the third Black Terrace location is refined. The findings are consistent with the 2018 Surveying+Spatial article by Bunn, Davies and Stewart (Bunn et al, 2018) i.e. the Black Terrace lies buried on land and the Pink and White Terraces locations lie across the shore
The Eighth Wonder of the World in New Zealand: Seismic studies confirm the new Hochstetter paradigm
Get PDFThe most famous tourist attractions in the southern hemisphere, in the nineteenth century were the Pink and White Terraces—New Zealand’s lost Eighth Wonder of the World. They were assumed lost in an1886 eruption. The unpublished 2018 data from passive seismic stations across the Lake Rotomahana overflow in the Taupō Volcanic Zone are examined for evidence of acoustic interfaces that may be traced to Te Tarata, the White Terraces, the stations were coincidentally placed over the reported course of the Kaiwaka Channel buried in the 1886 Tarawera eruption. There was no seismic evidence of the Channel at the reported altitude under either the Smith-Keam or Hochstetter paradigms. This absence is strong empirical negative evidence that the Kaiwaka Channel did not flow beneath today’s Lake Rotomahana overflow, as has been assumed since 1886 under the Smith-Keam paradigm. Unlike the seismic and GPR Black Terrace Crater and Te Tuhi’s Stream (aka Black Terrace Stream) bed evidence obtained by the same 2018 survey—there is no evidence of a pre-1886 eruption paleochannel beneath today’s overflow saddle at the lake and at the Kaiwaka altitude under the 1886 Smith-Keam paradigm or the contemporary Hochstetter paradigm, the latter based upon Hochstetter’s unique terrestrial survey of the Rotomahana Basin. The study reports strong empirical evidence contradicting the assumed Kaiwaka location and with it, the assumed locations of old Lake Rotomahana and the Pink and White Terraces. The Smith-Keam paradigm is thereby confounded. The seismic data provide concomitant empirical evidence for the Rotomahana altimetry and topography reported by Bunn and Nolden, who locate the Kaiwaka Channel 440 m west of the seismic stations. The Pink and White Terraces can no longer be assumed destroyed. They may yet be explored and recovered
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
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
