Der Schatten aus der Zeit. ‚Räumliche Kontinuitäten‘ im neolithischen und bronzezeitlichen Deponierungsgeschehen
No full textDie Annäherung an die Leitbegriffe der Tagung Raum, Gabe und Erinnerung wird im Beitrag anhand der besonderen sozialen Praxis im Umgang mit Objekten, nämlich ihrer Niederlegung versucht. Insbesondere die Gabe kann einen vielversprechenden Einstieg in die Diskussion um Prozesse des Erinnerns gewähren. Gleichwohl werfen die Deponierungen aufgrund ihrer meist nur schütteren Überlieferung stets Fragen nach der Repräsentativität des Quellenbildes und der davon abgeleiteten Deutungen auf. Die folgenden Betrachtungen widmen sich möglichen Kontinuitäten im neolithischen und bronzezeitlichen Deponierungsgeschehen und versuchen auszuloten, inwieweit sich im Quellenbild anhand von räumlichen Kontinuitäten Prozesse des Erinnerns zu erkennen geben.This article approaches the key concepts of the conference Space, gifts, and memory on the basis of specific social practices in handling objects, namely their deposition. In particular, gifts can impart a promising access to the discussion of processes of remembering. Nevertheless, because of the fact that they usually provide sparse information, depositions always evocate questions about the representativity of the sources and the interpretations deriving from them. The following observations address possible continuities in Neolithic and Bronze Age depositions and are an attempt to explore to what extent processes of remembering reveal themselves through spatial continuities
Raum, Gabe und Erinnerung. Einführung in denTagungsband
Full text linkDie Konzepte Raum – Gabe – Erinnerung entfalten durch ihr Zusammenspiel ein großes sozialhistorisches Erkenntnispotential für die altertumswissenschaftliche Forschung. Nicht nur Formen des Gabentausches oder des gesellschaftliche Erinnerns stehen in einem kulturspezifischen Kontext, sondern auch die Konstruktion des Raumes selbst. Der Band versammelt ein fachlich breites Spektrum von der Ethnologie über die prähistorische Archäologie bis zur klassischen Altertumskunde mit Beispielen von Irland bis Zentralasien. Die Beiträge eröffnen nicht nur neue empirische Einblicke, sondern auch neue theoretische Perspektiven für die Erforschung der Votivpraxis seit der Bronzezeit. Die Praxis der Votivgabe ist ein Kennzeichen der meisten antiken Religionen und reicht mit der Fortführung in der christlichen Kultpraxis bis in die Gegenwart.The concepts of space, gifts, and memory offer great potential for sociohistorical findings in classical studies. Forms of gift exchange and social memory have a culturally specific context, as does the construction of space itself. This volume brings together a broad spectrum of research, ranging from social anthropology to prehistoric and classical archaeology, with cases from Ireland to Central Asia. The contributions open up not only new empirical insights, but also new theoretical perspectives for the study of votive practices since the Bronze Age. The practice of votive offerings features in most ancient religions and extends into the present with its continued use in Christian rites
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
Light Microscopic Analysis of Mitochondrial Heterogeneity in Cell Populations and Within Single Cells
No full textHeterogeneity in the shapes of individual multicellular organisms is a daily experience. Likewise, even a quick glance through the ocular of a light microscope reveals the morphological heterogeneities in genetically identical cultured cells, whereas heterogeneities on the level of the organelles are much less obvious. This short review focuses on intracellular heterogeneities at the example of the mitochondria and their analysis by fluorescence microscopy. The overall mitochondrial shape as well as mitochondrial dynamics can be studied by classical (fluorescence) light microscopy. However, with an organelle diameter generally close to the resolution limit of light, the heterogeneities within mitochondria cannot be resolved with conventional light microscopy. Therefore, we briefly discuss here the potential of subdiffraction light microscopy (nanoscopy) to study inner-mitochondrial heterogeneities
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
