    ala foka is a warehouse and dwelling house of the Abui tribe who live in Takpala Traditional Village. In the construction of this house there is mathematical knowledge. This mathematical knowledge in the construction of fala foka can also be called ethnomathematics. This study aims to explore the mathematical knowledge contained in the construction of fala foka. Data collection methods include documentation, observation and interviews with indigenous people and teachers. The sources were obtained using snowball sampling. The results of this study are in the form of base 25 numbers in reed ties, geometry in the form of triangles and lines on the vertices, geometry in the form of rectangular pyramids on the roof of fala foka, geometry in the form of triangles on the roof shape, rectangles on the pelupu and dilation knowledge on the floor of each level of fala foka, the concept of rectangular area on the pelupu

    Introduction to the DHQ Special Issue : Digital Technology in the Study of the Past

    No full text
    Digital technology is transforming the assemblage and dissemination of historical information. Museums, libraries, archives, and universities increasingly modify their digital research infrastructures in order to make data open and available (see [Crane, Seales, and Terras 2009]; [Smithies 2014]; [Terras, Nyhan, and Vanhoutte 2013]; cf [Foka et al. 2017]). The imminent assessment and representation of historical data has admittedly challenged the boundaries of historical knowledge and generated new research questions [Drucker 2013] [Nygren, Foka, and Buckland 2014] #nygren2016 [Westin 2014] #westin2015[Chapman, Foka, and Westin 2016] [Foka and Arvidsson 2016]. The process of reconstructing, visualizing and rendering historical data has equally developed together with technology [Westin, Foka, and Chapman 2018]. This is the case in both academic and heritage contexts and in less immediately obvious popular uses, such as the increasingly significant presence and use of history within video games [Chapman 2016]. Regardless of specific context, as this collection of articles shows, the process of digitally capturing and representing historical data is often analogous to and determined by the digital platform used.</p

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Native and alien ichthyofauna in coastal fishery of Rhodes (eastern Mediterranean) (2002-2010)

    Rhodes Island (southeastern Aegean) is located in a geographically crucial region subjected to biological invasions. Among the 108 alien species recorded, 30 are fish, all of Indo-Pacific/Red Sea origin introduced via Suez through Lessepsian migration (Corsini-Foka et al., 2015; Corsini-Foka and Kondylatos, In press; Kondylatos and Corsini-Foka, In press). In this oligotrophic area, fishery production is limited, due to the paucity of species of commercial interest and their low abundance, while adapted infrastructures for fish landing and marketing are absent. Coastal fishery has dominated during the last twenty years (ELSTAT, 2015). Within 2002-2010, the Hydrobiological Station of Rhodes conducted experimental boat seining surveys, using exclusively a professional 12m fishing boat, at 5-30 m depth, in the Gulf of Trianda (sandy mud, Posidonia meadows). The 94 carried out hauls (7-18 hauls/year), produced a total fish biomass of approximately 4400 Kg, recording 97 fish (86 native, 11 alien) and 4 cephalopod species (3 native, 1 alien). Fish species ranged from 32 to 63/year, whereas aliens ranged from 5 to 8 species. Almost steadily present since 2002, were earlier colonizers such as Apogonichthyoides pharaonis, Siganus rivulatus, Siganus luridus, Stephanolepis diaspros and more recent ones as Pteragogus trispilus, Sphyraena chrysotaenia and Fistularia commersonii, while Lagocephalus sceleratus, firstly recorded in 2005, occurred regularly since 2007; the presence of Lagocephalus suezensis, Sphyraena flavicauda and Upeneus pori was scattered since their first records in 2004-2005. Alien fish commercially important are the Siganids, S. chrysotaenia and surprisingly F. commersonii. In terms of biomass per haul, alien fish ranged from 0 to 18.5 Kg, native from 1.5 to 182 Kg. Catches were dominated by Centracanthidae (Spicara spp.) and Sparidae (Boops boops), sometimes by other native such as Oblada melanura, Diplodus spp., Chromis Chromis and others. The present work aims to contribute in the limited literature on the demersal fish species assemblage of the SE Aegean over time, given the ongrowing influx of aliens in the area

    Variations on the Author

    “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

    We 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

    Deviant Women: Cultural, Linguistic and Literary Approaches to Narratives of Feminity

    No full text
    This multidisciplinary collection of articles illuminates the ways in which the concept of female deviance is represented, appropriated, re-inscribed and refigured in a wide range of texts across time, cultures and genres. Such a choice of variety shows that representations of deviance accommodate meaning-making spaces and possibilities for resistance in different socio-cultural and literary contexts. The construct of the deviant woman is analysed from literary, sociolinguistic and historical-cultural perspectives, revealing insights about cultures and societies. Furthermore, the studies recognise and explain the significance of the concept of deviance in relation to gender that bespeaks a contemporary cultural concern about narratives of femininity.Tiina Mäntymäki, Marinella Rodi -Risberg, Anna Foka: "Introduction" 9 // Anna Foka: "Beyond Deviant: Theodora as the Other in Byzantine Imperial Historiography" 29 // Wang Lei: "Ghosts and Spirits as the objet a in Pu Songling’s Strange Tales from Make -Do Studio" 49 // Sanna Karkulehto and Ilmari Leppihalme: "Deviant Will to Knowledge: The Pandora Myth and Its Feminist Revisions" 69 // Tiina Mäntymäki: "Carnivalesque Masquerade.

    Dispelling the Myths Behind First-author Citation Counts

    We 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
