An Interview with Elizabeth Grosz: Geopower, Inhumanism and the Biopolitical
No full text© 2017, © The Author(s) 2017. This article is an interview with Elizabeth Grosz by Kathryn Yusoff and Nigel Clark. It primarily addresses Grosz’s approaches to ‘geopower’, and the discussion encompasses an exploration of her ideas on biopolitics, inhuman forces and material experimentation. Grosz describes geopower as a force that subtends the possibility of politics. The interview is accompanied by a brief contextualizing introduction examining the themes of geophilosophy and the inhumanities in Grosz’s work
Labirintos autobiográficos: Lygia Clark e Hélio Oiticica
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2015.Com este trabalho de dissertação de Mestrado pretendemos mergulhar no imenso arquivo de cartas e escritos de artista de Hélio Oiticica e Lygia Clark, e também em trabalhos artísticos e proposições de vivências que ambos compuseram, inventaram e criaram entre 1950 e 1980. Para isso, buscamos criar modos de leitura desse arquivo que possam fazer aparecer os vestígios, as marcas e os rastros pulsionais que estes artistas deixaram em suas obras e, também, que suas obras deixaram nestes artistas. A amizade de Hélio e Lygia, devido à distância geográfica entre os dois, foi estabelecida principalmente por meio da correspondência epistolar, e poderia ser aqui definida tal qual um afeto como pensamento ? pensamento no sentido que quer Deleuze, quando diz que pensar é sempre experimentar e não interpretar, ?e a experimentação é sempre o atual, o nascente, o novo?; mas também no sentido de Jean-Luc Nancy, quando diz que ?corpo e pensamento são um mútuo tocar-se?. Os corpos e pensamentos de Hélio e Lygia tocam-se por meio da linguagem, tocam-se, contaminam-se, mas não se confundem. Assim, seus corpos e seus pensamentos, entrelaçados, devoradores e devorados, não são mais que o toque de um no outro, o toque da distância de um em relação ao outro e de um no interior do outro. As escritas de Hélio e Lygia operavam uma espécie de justaposição de textos por técnicas de montagem e de multiplicação que nos revela as contaminações mútuas entre as criações, as teorias e as críticas, apontando para a escrita a partir da leitura; por isso, nessas escritas, podemos entreouvir múltiplas vozes que nelas ecoam. Suas escritas de si são vistas, então, como experiência, e suas vidas são aqui tratadas como vidas vividas pela experimentação. Desse modo, podemos encontrar, em suas escritas e vivências, singularidades que ligam-se umas às outras e que estão sempre produzindo diferenças. A busca desses vestígios no corpus de Hélio e Lygia se faz por um percurso não linear, sem lógica de entrada nem de saída, sem busca por origem, como em uma espécie de labirinto. Os labirintos autobiográficos de Lygia e Hélio seriam feitos de múltiplos, contínuos e descontínuos caminhos que estão sempre a se construir e se desconstruir. Seus escritos foram compostos por meio de tensões que operariam nas bordas e nos limites do corpo e da linguagem; sustentadas também no limite entre realidade e ficção. Suas práticas artísticas também operavam tensões ao se abrirem para o público participador e ao se deixarem ser atravessadas pelo que é exterior, por isso, suas vidas e suas obras estão fortemente permeadas pelas relações entre arte e experiência. Para percorrer esses labirintos,nos valemos do método otobiográfico que Derrida postula a partir de Nietzsche, com o objetivo de buscar a vida, seus rastros e vestígios nesse arquivo, e não de atribuir sentidos ou significados para suas vidas-obras. Hélio e Lygia, por meio das leituras-escrita e das escritas-leitura das cartas trocadas entre eles, se colocaram à escuta um do outro, mostrando-se sempre como um ser ainda por vir, em constante processo de construção de um si mesmo; e por isso nunca acabados, permanecendo como fragmentos caminhando no labirinto de um programa in progress.Abstract : With this dissertation we intend to delve into the immense archive of letters and artist writings of Hélio Oiticica and Lygia Clark, and also artwork and proposals of experiences they both made up, invented and created between 1950 and 1980. To this end, we seek to create reading techniques for these files that can bring up the traces, marks and instinctual traces these artists left in their works and also that their works have left in them. The friendship of Hélio and Lygia, due to the geographical distance between the two of them was established mainly through written correspondence, and could be defined here as is an affection as thinking - thinking in the sense that Deleuze means when he says that thinking is always experimenting and not interpreting, ?to think is to experiment, but experimentation is always that which is in the process of coming about.?; but also meaning what Jean-Luc Nancy says, that ?body and mind are a mutual touching.? The bodies and thoughts of Hélio and Lygia touch each other through language, they touch, contaminate eather other, but they don't get mixed up. Thus, their bodies and their thoughts, entangled, devouring and devoured, are nothing more than one touching another, the touching of the distance relative to each other and of one inside the other. The writings of Hélio and Lygia operated a kind of juxtaposition of texts by assembly techniques and multiplying that reveals the mutual contamination between creations, theories and criticism, pointing to writing from reading; that is why in these writings we can overhear multiple voices echoing. His writings of himself are seen, then, as experience, and their lives are treated here as lives lived by experimentation. Thus, we can find in their writings and experiences, singularities that bind to each other and are always producing differences. The search for these traces on Hélio and Lygia?s corpus is made on a non-linear path without input or output logic, without a search for origin, as in some kind of a maze. The autobiographical mazes of Lygia and Hélio would be made of multiple continuous and discontinuous paths which are always building and deconstructing. Their writings were composed by impasses operating at the edges and boundaries of body and language; also held at the boundary between reality and fiction. Their artistic practices also operated tensions when they opened to the participanting public and when they let themselves be crossed by what is outside, that is why their lives and works are strongly permeated by the relations between art and experience. To cross these labyrinths, we make use of the otobiographical method that Derrida postulates from Nietzsche, in orderto seek their life, tracks and traces in this work, and not to attribute meanings to their lives-works. Hélio and Lygia, through the reading-writing and writing-reading of the letters exchanged between them, placed themselves listening to each other, showing themselves as a being yet to come, in a constant process of creating themselves; and therefore never finished, remaining as fragments caminhando in the labyrinth of a programa in progress

Tinakta I., (N), N 82 °W, 2.3 km (5 ° 11 ʹ 50 ʺ N, 119 ° 54 ʹ E), Tawi Tawi Group, Sulu Archipelago, Philippines, 18–22 m depth coll. Albatross Philippine Expedition 1907 – 9, U.S. Bureau of Fisheries, 21 February 1908. Paratype: 1 Ƥ (6.64 × 5.10 mm) (USNM 1150302), same data as holotype. Diagnosis. Holotype 3: carapace subrectangular, about 1.2 times wider than long (Figs. 1 A, C), frontal margin gently sinuous, about a third carapace width (Figs. 1 A, C); dorsal surface smooth, gently convex anteriorly, posteriorly, without indication of regions (Figs. 1 A, C, 2 B, C). Anterolateral margin short, entire, gently convex, unarmed; posterolateral margin gently concave (Fig. 1 A, C). Cornea pigmented, small (Figs. 1 A, C, 2 A, C). Small gape present between third maxillipeds when closed; ischium subquadrate; merus quadrate, distinctly shorter than ischium, anteroexternal angle of distinctly right angled (Fig. 3 A). Chelipeds subequal (Fig. 1 A, C), outer surfaces smooth, with prominent keel on ventral margin extending almost to tip of finger (Fig. 2 B, C); dorsal margin of propodus smooth, unarmed; inner margin of carpus with low tooth, inner margin finely denticulate to almost smooth (Figs. 1 A, C, 2 C). Ambulatory legs relatively long, surfaces smooth, margins lined with numerous setae (Fig. 1 A, C). Thoracic sternum relatively broad; surface microscopically pitted; sternites 1, 2 completely fused, separated from sternite 3 by distinct transverse suture; sternites 3, 4 fused except for lateral parts (Fig. 1 B). Abdomen relatively broad, somite 3 broadest; telson broadly triangular (Figs. 1 B, 3 B). G 1 gently curved outwards, relatively stout, inner margin of subdistal part with numerous long sharp setae (Fig. 4 A-D); G 2 much longer than G 1, distal segment longer than basal segment, distinctly sinuous with tip recurved (Fig. 4 E-H). Female. The female agrees with the male in all major non-sexual characters. The abdomen is ovate, not covering entire thoracic sternal surface. The vulva is typical for members of the genus, being relatively large, occupying anterior half of thoracic sternite 6, without visible sternal vulvar cover. Etymology. The name is arbitrarily derived from the Museum Sorting Centre of the Smithsonian Institution at Alexandria, Washington D.C. in acknowledgement to all the staff at Silver Hill for making our EDIT (European Distributed Institute of Taxonomy) group so welcome. It is used as a noun in apposition. Remarks. Notonyx musuppocenta n. sp., is allied to N. nitidus A. Milne-Edwards, 1873, but can be separated from it by the anteroexternal edge of the third maxilliped being more angular and the ischium relatively shorter (Fig. 3 A) (anteroexternal angle more rounded with a proportionately longer ischium in N. nitidus; Clark & Ng 2006: fig. 3 B), the male abdomen, especially somite 3 and telson, is relatively broader (Fig. 3 B) (somite 3 and telson of male abdomen relatively less broad; Clark & Ng 2006: fig. 3 F); the G 1 is relatively stouter with the inner margin of the subdistal part possessing numerous sharp setae (Fig. 4 A-D) (G 1 relatively more slender with only short spines on the inner margin of the subdistal part in N. nitidus; Clark & Ng 2006: fig. 3 H, I), and the G 2 has the distal segment distinctly sinuous with the tip recurved (Fig. 4 E-H) (strongly curved, appearing hook-like with leaflike distal part in N. nitidus; Clark & Ng 2006: fig. 3 G).Published as part of Clark, Paul F. & Ng, Peter K.

Notonyx rayneri Ng & Clark, 2010, n. sp.
No full textNotonyx rayneri n. sp. (Figs. 4–6) Notonyx nitidus – Balss 1938: 74 (not Notonyx nitidus A. Milne-Edwards, 1873). Material examined. Holotype male (17.30 × 10.60 mm) (NHM 1858.172), stn 529, island of Vanua Levu, Nandi, Fiji, presented by Admiralty, coll. F. N. Rayner, voyage of HMS Herald. Diagnosis. Holotype: carapace (Fig. 4 A, B) transversely subrectangular, 1.63 × wider than long, frontal margin almost straight. Anterolateral margin short, entire, unarmed; posterolateral margin gently concave, slightly diverging towards posterior part. Dorsal surface of carapace smooth, without indication of regions except for relatively shallow gastro-cardiac grooves; dorsal surface convex anteriorly, gently convex posteriorly. Eyes filling orbit (Fig. 4 C); cornea pigmented, small. Small gape present between third maxillipeds (Fig. 5 A) when closed; merus quadrate, anterior margin gently concave, slightly shorter than ischium; anteroexternal angle of merus just above tip of exopod. Chela (Fig. 4 D, E) with outer surfaces almost smooth, punctate in parts, ventral margin with prominent keel extending almost to tip of finger; dorsal margin of propodus smooth, unarmed; inner margin of carpus with very low tooth, inner margin denticulate. Walking legs (Fig. 4 A) relatively short. Thoracic sternum relatively broad; surface pitted; sternites 1, 2 completely fused, separated from sternite 3 by prominent transverse suture; sternites 3, 4 fused except for lateral parts of sutures. Male abdomen (Fig. 5 B) relatively broad, third somite broadest; telson triangular, lateral margins gently sinuous. G 1 (Fig. 6 A–D) relatively slender, gently curved outwards, subdistal part with low hump-like structure, surface lined with numerous small spines, distal part not prominently elongated; outer lower margin with prominent spur-like projection. G 2 (Fig. 6 E, F) sinuous, longer than G 1, distal segment longer than basal segment; junction between distal, subdistal segments with concave surface surrounded by short serrae; distal part appears spoon-shaped. Etymology. The species is named after the surgeon on HMS Herald who collected the type specimen. Remarks. Balss (1938: 74) reported a male (12.0 × 9.0 mm) from Namuka, Viti Levu, Fiji, without figures or comments. The present specimen from Fiji is relatively larger. They are presumed to be conspecific in view of their provenance. The specimen was originally died (Fig. 4 A) but was rehydrated so the abdomen and gonopods could be studied. The carapace form of N. rayneri n. sp. is superficially similar to N. latus although it is proportionately broader in the new species (width to length ratio 1.60 vs. 1.40). Notonyx rayneri n. sp. can also be separated from N. latus by its relatively more slender male abdomen (Fig. 5 B) (cf. Ng & Clark 2008: fig. 2 E), the G 1 is sinuous in shape with the distal part blunt and subtruncate (Fig. 6 A–D) (G 1 almost straight with the distal part prominently extended and curved in N. latus, Ng & Clark 2008: fig. 3), and the distal part of the flagellum is gently curved (Fig. 6 E, F) (G 2 tip is bent back on itself to form S-shaped structure in N. latus, Ng & Clark 2008: fig. 4). The G 1 structure of N. rayneri n. sp. most closely resembles that of N. kumi but the two species differ in several features. The carapace of N. rayneri n. sp. is relatively broader (width to length ratio 1.60 vs. 1.4), the male telson is relatively broader with gently concave margins (Fig. 5 B) (male telson relatively more acute in N. kumi with almost straight lateral margins, Naruse & Maenosono 2009: fig. 2 a), there is a prominent spurlike projection on the outer lower margin of the G 1 (Fig. 6 A, B) (margin almost entire in N. kumi, Naruse & Maenosono 2009: fig. 2 b, c), the tip of the G 1 is not projected beyond the swollen subdistal part (Fig. 6 A–D) (distal part of G 1 extends beyond the swollen subdistal part in N. kumi, Naruse & Maenosono 2009: fig. 2 b, c). Compared to N. sagittifer n. sp., the carapace of N. rayneri n. sp. is relatively broader (width to length ratio at 1.60 vs. 1.36), the chelae are proportionately stouter (Fig. 4 D, E vs. Fig. 1 C), and the G 1 is relatively stouter, more sinuous, with the distal part not projecting beyond the swollen subdistal part (Fig. 6 A, B) (G 1 relatively longer, curved outwards with the distal part prominently elongated in N. sagittifer n. sp., Fig. 3 A, B). Although near the type locality of N. rayneri n. sp. is closest to N. nitidus (New Caledonia), their carapace proportions, structures of the third maxillipeds, male abdomens and G 1 s are completely different (see Clark & Ng 2006).Published as part of Ng, Peter K.
