Reseña de "From Ethnomathematics to art-design matrices and cyclic matrices" de Paulus Gerdes
No full textIn this review, we present the ethnomathematics investigations undertaken in the last three decades by Paulus Gerdes, a Mozambique mathematics educator. The author presents a variety of discussions with several examples that explains the relationship of mathematics to human activities. We present, among other things, the cyclic matrices and its interrelationships with the African cultural contexts, undoing the erroneous impression that mathematics can be seen disconnected from the feature, which makes the individuals in their socio-cultural environments. Gerdes shows us that there's mathematics in different cultures and this helps us to realize the beauty of the symmetries and patterns, in addition to allowing depth between mathematics and human actions in the art

No full textSowohl bei der Incel-Ideologie als auch beim Jihadismus handelt es sich um hochgradig misogyne und antisemitische Weltanschauungen. Erstere wird bislang vor allem im Hinblick auf ihren Antifeminismus analysiert, letztere gerät wissenschaftlich überwiegend hinsichtlich ihres Antisemitismus in den Blick – selten werden jedoch beide Aspekte gemeinsam untersucht. Dies änderte sich auch nicht angesichts der Massaker der Hamas und anderer islamistischer Gruppen am 7. Oktober 2023, welche die tödliche Verstrickung von Frauenhass und Antisemitismus innerhalb des Jihadismus unübersehbar machte. Dieser Beitrag analysiert die auf den ersten Blick sehr unterschiedlich erscheinenden Weltanschauungen, setzt sie zueinander in Beziehung und interpretiert sie als verschiedene Formen gegenwärtiger Rebellionen gegen die Moderne. Anhand empirischer Beispiele aus den Schriften von Sayyid Qutb, einem Hauptideologen des Jihadismus, sowie dem größten Incel-Forum incels.is wird aufgezeigt, wie Antisemitismus und Misogynie jeweils miteinander verwoben sind und auf welche Weise sich anhand der Weltanschauungen autoritäres Potenzial zum antidemokratisch autoritären Syndrom verdichten kann

Der Postfeminismus-Vorwurf: Beobachtungen zum feministischen Selbstkonzept junger Theaterkünstlerinnen und Journalistinnen am Beispiel des Missy Magazine
No full text"Popkulturell arbeitende Künstlerinnen stehen spätestens seit den Studien der Kulturwissenschaftlerin Angela McRobbie unter dem Verdacht, feministische Anliegen zu kommerzialisieren und zu trivialisieren. Der Vorwurf des Postfeminismus ist auch in Deutschland als Debatte 'alter versus neuer Feminismus' in Bezug auf die Kunst junger, erfolgreicher Frauen häufig zu hören. Im Missy Magazine werden verschiedene populärkulturell arbeitende Künstlerinnen porträtiert, wobei stets ein Bezug zum Feminismus hergestellt wird. Dieser Beitrag widmet sich den im Missy Magazine vorgestellten Theatermacherinnen und ihrem feministischen Selbstkonzept. Die Kategorie 'Postfeminismus' wird dabei einer kritischen Prüfung unterzogen und mit dem Selbstbild zeitgenössischer Theatermacherinnen abgeglichen. Unter Einbezug der Theorie des postdramatischen Theaters werden Gemeinsamkeiten einer jungen Theatergeneration herausgestellt." (Autorenreferat)"Since cultural scientist Angela McRobbie began publishing her studies, at the latest, female artists working in pop culture have been suspected of commercializing and trivializing feminist issues. The reproach of post-feminism can often be heard in Germany too in the debate about 'old vs. new feminism' in relation to the art of young and successful women. Missy Magazine portrays various pop cultural female artists, whereby there is always some reference to feminism. This article is dedicated to the female theatre-makers portrayed in Missy Magazine and their feminist self-conceptions. The category 'post-feminism' is thereby subjected to a critical examination and is compared to contemporary female theatre-makers' self-image. Drawing on the theory of post-dramatic theatre, the similarities that exist in a young theatre generation are underlined." (author's abstract

Ecological information and abiotic data for assemblages where this species was collected can be found in Gerdes <i>et al.</i> (2019a, b).</p> <p> <b>DNA barcode.</b> Full COI barcodes (652 bp) were obtained for the holotype ZMH 26363 and the four paratypes ZMH 26364, 26365 and SMF 38801, 38802 of <i>Pachycara angeloi</i> <b>sp. nov.</b>, and uploaded to GenBank (https://www. ncbi.nlm.nih.gov/genbank/) with the following accessions: ZMH 26363: MW 888718, ZMH 26364: MW 888716, ZMH 26365: MW 888717, SMF 38801: MW 888715, SMF 38802: MW 888714. Pairwise genetic distances between specimens range from 0.0–0.3% sequence divergence (0–2 bp). Thus, intra-specific variation was low and does not reflect different vent sites.</p> <p>Additional relevant voucher information, photos, DNA barcodes, used primer pairs and trace files were uploaded to the Barcode of Life Data Systems (BOLD; www.boldsystems.org) (Ratnasingham & Hebert 2007), project “Indian Ocean Hydrothermal Vent Fauna—INDEX”—subproject “Indian Ocean Hydrothermal Vent Megafauna” in the public dataset “INDEX_Megafauna_2021_1”.</p> <p> <b>Remarks.</b> The new species is included in the genus <i>Pachycara</i> based on the characters defined by Anderson (1994).</p> <p> <i>Pachycara angeloi</i> <b>sp. nov.</b> is different from all other described <i>Pachycara</i> species in having 85–87 total vertebrae (vs. 92–125 in all other species). Thus, the new species expands the lower limit of total number of vertebrae of the genus <i>Pachycara</i> (92 according to Corbella & Møller 2014) down to 85.</p> <p> Further detailed comparisons with the five <i>Pachycara</i> species known from the Indian Ocean and the four <i>Pachycara</i> species associated with hydrothermal vents were performed based on the morphological characters provided by Anderson (1989), Anderson & Bluhm (1997), Anderson <i>et al.</i> (2016), Biscoito & Almeida (2004), Geistdoerfer (1994), Møller (2003), Møller & King (2007) and Shinohara (2012). Different characters between the new species and each of all nine congeners are indicated in bold in Table 2. Below are counts for the respective characters for the species are given in brackets.</p> <p>In comparison with all nine congeners, the new species has lower numbers of total vertebrae (85–87 vs. 93– 123), caudal vertebrae (57–59 vs. 67–91), dorsal-fin rays (78–80 vs. 86–115) and anal-fin rays (58–62 vs. 70–95).</p> <p> The following five species out of all nine congeners have higher numbers of precaudal vertebrae than <i>P. angeloi</i> <b>sp. nov.</b> (27–28): <i>P. caribbaeum</i> (31–33), <i>P. cousini</i> (29), <i>P. saldanhai</i> (31–34), <i>P. shcherbachevi</i> (29–32) and <i>P. thermophilum</i> (31), whereas the following three congeners have lower numbers of precaudal vertebrae: <i>P. andersoni</i> (24–26), <i>P. priedei</i> (22–23) and <i>P. rimae</i> (26). <i>P. arabica</i> (27) has overlapping precaudal vertebrae counts with the new species.</p> <p> Moreover, <i>P. saldanhai</i>, <i>P. shcherbachevi</i> and <i>P. thermophilum</i> differ from the new species in having a pelvic fin (vs. absent in the new species), higher numbers of pectoral-fin rays (18–19 in <i>P. saldanhai</i>, 16–17 in <i>P. shcherbachevi</i>, 17–18 in <i>P. thermophilum</i> vs. 13–15 in the new species) and higher numbers of gill rakers (15–18 in <i>P. saldanhai</i>, 16 in <i>P. shcherbachevi</i>, 15–16 in <i>P. thermophilum</i> vs. 12 in the new species). In comparison with the new species, <i>P. saldanhai</i> and <i>P. shcherbachevi</i> have a different lateral line configuration (ventral & mediolateral). <i>Pachycara caribbaeum</i> and <i>P. cousini</i> differ from the new species in having fewer caudal-fin rays (10 in <i>P. caribbaeum</i> and <i>P. cousini</i> vs. 11–12 in <i>P. angeloi</i> <b>sp. nov.</b>) and more gill rakers (13 in <i>P. caribbaeum</i>, 15 in <i>P. cousini</i> vs. 12 in <i>P. angeloi</i> <b>sp. nov.</b>). <i>Pachycara caribbaeum</i> differs also from the new species in having a pelvic fin (vs. no pelvic fin) and <i>P. cousini</i> also has more pectoral-fin rays than <i>P. angeloi</i> <b>sp. nov.</b> (17 vs. 13–15).</p> <p> <i>P. andersoni</i> and <i>P. priedei</i> differ also from the new species in having more pectoral-fin rays (18–20 in <i>P. andersoni</i>, 16–17 in <i>P. priedei</i>, vs. 13–15 in <i>P. angeloi</i> <b>sp. nov.</b>), more gill rakers (16–17 in <i>P. andersoni</i>, 14 in <i>P. priedei</i> vs. 12 in the new species) and different lateral line configurations (a ventral and mediolateral line in <i>P. andersoni</i> and <i>P. priedei</i> vs. a single mediolateral lateral line in the new species). Additionally, <i>P. priedei</i> has fewer caudal-fin rays (10) than <i>P. angeloi</i> <b>sp. nov.</b> (11–12).</p> <p> In comparison to the new species, <i>P. rimae</i> and <i>P. arabica</i> have fewer caudal-fin rays (10 and 9 vs. 11–12). Additionally, <i>P. arabica</i> differs from the new species in having more pectoral-fin rays (19 vs. 13–15) and gill rakers (17 vs. 12) as well as a different lateral line configuration (a ventromediolateral line vs. a single mediolateral lateral line). <i>Pachycara rimae</i> is also different from <i>P. angeloi</i> <b>sp. nov.</b> in having a pelvic fin (vs. no pelvic fin present in the new species), fewer caudal-fin rays (9 vs. 11–12), gill rakers (10 vs. 12) and suborbital pores (5 vs. 6–7).</p> <p> This paper describes the 29 th species of <i>Pachycara</i>, which is the 5 th to be described from specimens collected only from chemosynthetic environments and the 6 th known from the Indian Ocean.</p>Published as part of <i>Thiel, Ralf, Knebelsberger, Thomas, Kihara, Terue & Gerdes, Klaas, 2021, Description of a new eelpout Pachycara angeloi sp. nov.
