An illustrated prehistory of the Jubbah oasis: reconstructing Holocene occupation patterns in north-western Saudi Arabia from rock art and inscriptions
No full textA systematic survey of rock art and associated archaeological features in the Jubbah oasis provides evidence of Holocene occupation from the early Holocene to the present. In total 1249 panels with rock art and inscriptions, and 159 archaeological sites, were recorded on twelve different jebels. Analyses of rock art content and engraving stratigraphy indicate that the iconic Jubbah style had a long tradition among pre-pastoral hunters and continued to be used by early herders. We also identify a distinct body of rock art that pre-dates the Jubbah style and may be associated with a nearby Epipalaeolithic site. Our systematic dataset identifies a body of Bronze Age rock art that is further supported by the material culture and radiocarbon dates obtained from the remains of disturbed cairns. The rock art in Jubbah appears to have been created throughout the Holocene occupation of the oasis and similarities in the representation of animals, choice of location and content of rock art scenes are evident from the Bronze Age to the early modern period, and perhaps into the twentieth century. Moreover, rock art and epigraphy suggest that occupation phases in Jubbah were sustained long enough for the repeated development of unique local characteristics throughout the Holocene
Mental symptoms in the Akkadian diagnostic handbook: a study of patterns in the description of depression, anxiety, and madness
Full text linkThis study is concerned with reconstructing patterns in the description of mental distress, disturbance, and disorder in diagnostic descriptions from medical texts recorded in Akkadian from the first millennium BCE. In the service of this aim, the study also offers a theoretical framework for the approach to mental disorder in Akkadian medical diagnostic texts. With a few exceptions, previous studies of mental disorder in the Akkadian medical tradition have relied in large part on the method of retrospective diagnosis, which, for reasons to be set out, can be a problematic methodology. This study offers an alternative framework that defines objects of inquiry that can be meaningfully applied to the Akkadian sources. This framework incorporates principles from the fields of the history, philosophy, and anthropology of medicine and takes into account the type of information recorded in the Akkadian medical diagnostic texts. Organised around three core symptoms of ašuštu "Depression", ḫīp libbi "Heartbreak", and ṭēmu šanû/nakāru "The mind alters/changes", this study investigates the occurrences of these terms and expressions in the Diagnostic Handbook to determine an initial repertoire of symptoms that recur with these. These recurring symptoms are taken to reflect patterns in the description of mental symptoms and are supplemented with medical therapeutic texts, especially those for ghost- and witchcraft-induced illness. Mental symptoms organised with the core symptoms of this study are primarily expressed through the paradigms of change and somatisation. The recurrence of these patterns reveals native paradigms in the expression of mental symptoms that can be explained with intercultural parallels and that begin to reveal the ways in which disorders with a strong cognitive and affective component were made comprehensible in a clinical context
Rock art provides new evidence on the biogeography of kudu (Tragelaphus imberbis), wild dromedary, aurochs (Bos primigenius) and African wild ass (Equus africanus) in the early and middle Holocene of north-western Arabia
Full text linkAim Our knowledge of the prehistoric distribution of animal species is so far largely dependent on the location of excavated archaeological and palaeontological sites. In the absence of excavated faunal remains, many species that were present in the Levant and North Africa have been assumed to have been absent on the Arabian Peninsula. Here, we explore representations of four species that were identifiable in the rock art, but had not previously been reported in north-western Arabia. Location Jubbah and Shuwaymis UNESCO world heritage rock art sites in Ha'il province, north-western Saudi Arabia. Methods In total, the rock art panels surveyed and recorded in Jubbah and Shuwaymis contain 6,618 individual animal depictions. Species were identified based on diagnostic features of the anatomy. The resulting dataset was then compared to the faunal spectrum reported in the (archaeo)zoological literature. Results The rock art dataset provides evidence that the distributions of lesser kudu (Tragelaphus imberbis), wild camel and African wild ass (Equus africanus) extended into the north-west of Arabia and that the engravers may have had knowledge of aurochs (Bos primigenius). Main conclusions The presence of previously undocumented mammal species in Arabia provides new information regarding their distribution, as well as the types of habitat and vegetation that were available in prehistoric landscapes. Moreover, the presence of kudu on the Arabian Peninsula indicates that the identification of palaeo-distributions based exclusively on faunal remains may miss key species in the Afro-Eurasian faunal exchange
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
