Die Tode der Fotografie
No full textWas verstehen wir vom Tod, wenn wir Fotografien von Verstorbenen betrachten? Und wen oder was sehen wir dabei? Wie gehen wir mit den Fotos um? Wo platzieren wir sie, wem zeigen wir sie, wo verbergen wir sie? Welche Art Beziehung unterhalten wir zu den Toten mit Hilfe ihrer Fotografien, und wie verständigen wir uns über unser Verhältnis zu ihnen? Ist uns dabei das Medium präsent, oder bleibt es eine durchsichtige Membran?
Das Buch Die Tode der Fotografie geht diesen Fragen nach und untersucht Formen und Verwendungsweisen von Fotografien in den Toten-, Begräbnis- und Erinnerungspraktiken westlicher Kulturen. Katharina Sykora ist Professorin für Kunstgeschichte des 19. und 20. Jahrhunderts an der Hochschule für Bildende Künste Braunschweig. Für das Projekt Die Tode der Fotografie erhielt sie 2007/08 die Forschungsförderung Pro Geisteswissenschaft/Opus Magnum der VolkswagenStiftung und war 2008 Research Resident am Rockefeller Center Bellagio, Italien. Das Buch ist erschienen unter dem Titel: Katharina Sykora, Die Tode der Fotografie, Bd. I, Wilhelm Fink Verlag, München 2009.

Mortoniella (Mortoniella) bifurcata Sykora 1999
No full textMortoniella (Mortoniella) bifurcata Sykora, 1999 Fig. 18 Mortoniella bifurcata Sykora 1999: 382 [member of flinti subgroup]; Blahnik and Holzenthal 2008: 70 [member of bilineata group]. This species is probably most closely related to M. flinti Sykora. Both species are very dark in color and have 2 white wing bands, and also have the apex of the dorsal phallic spine modified, bifurcate or asymmetric (as in the specimen illustrated) in M. bifurcata and trifurcate in M. flinti. The other two species in the group are dark in color, without wing bands, and have the dorsal phallic spine symmetric and either narrowed or rounded apically. The most diagnostic difference between M. bifurcata and M. flinti is in the apex of tergum X, which is only very shallowly notched apically in M. bifurcata and much more distinctly so in M. flinti. The difference in the shape of the inferior appendages, as illustrated by Sykora, is inaccurate and does not seem to be diagnostic. However, the spines from the mesal pockets of the inferior appendages in M. bifurcata are somewhat longer than In M. flinti; also, the paramere appendages are longer, but not nearly as long as in M. tanyrhabdos, n. sp. Adult —Length of forewing: male 3.8 mm. Forewing with forks I, II, and III present, hind wing with forks II and V. Spur formula 0:3:4. Overall color dark brownish-black (fuscous). Mesotarsi whitish, except at very apex. Tibial spurs slightly darker than legs, not strongly contrasting with legs. Forewing with distinct white wing bar at anastomosis, and evidence (on one wing of somewhat rubbed specimen) of second white wing bar on proximal part of wing, closer to base than anastomosis. Male genitalia —Ventral process of segment VI posteriorly projecting, prominent, narrow basally, length about 3½ times width at base. Tergum VIII narrow, subtending ventral margin of segment IX, membranous connection to tergum IX moderately elongate. Segment IX with anterolateral margin rounded and produced in ventral half, posterolateral margin nearly straight, without distinct projection; segment deeply mesally excised dorsally and ventrally, forming lateral lobes, separated dorsomesally by less than ½ width of segment. Tergum X elongate, apex rounded, with only slight mesal invagination, lateral margins subparallel, with paired longitudinal ridges extending from basolateral margins to past midlength, ridges somewhat converging posteriorly; tergum with bluntly rounded ventrolateral lobes, ventromesal lobes absent. Inferior appendages with short rounded dorsolateral lobes, each with fringing row of very elongate setae, and short, bluntly rounded, ventromesal projection, subtending apical spine-like projections of mesal pockets of inferior appendages. Mesal pockets of inferior appendage with moderately elongate, posterodorsally curved, spine-like, apicoventral projections, projecting distinctly below ventral margin of phallicata. Paramere appendage relatively elongate, not extending to apex of dorsal phallic spine, narrow, nearly uniform in width, apex acute, strongly bent in about apical 1/3; fused basal segments of appendages articulating near base of dorsal phallic spine. Phallobase with evident rounded, laterally compressed, dorsomesal apodeme. Dorsal phallic spine, as viewed laterally, relatively narrow throughout, tapering apically, slightly dorsally curved in about apical 1/4, apex acutely bifid in holotype, unilaterally asymmetric in paratype (Fig. 18D); base of spine with short, curved stalk and distinct, rounded, ventral deflection in basal ¼; spine, as viewed dorsally, nearly uniformly narrow in width throughout length, apex bifid or acute and asymmetric. Phallicata with elongate sclerotized basodorsal projection, articulating with rounded ventral deflection of dorsal phallic spine, basolaterally with small rounded projection, ventral margin sclerotized and strongly arched. Endophallic membrane simple in structure, without membranous lateral lobes; phallotremal spines absent.

Sequenza di impulsi per acquisire dati di risonanza magnetica nucleare in funzione del rilassamento longitudinale
No full textL' invenzione introduce una nuova categoria di sequenze di impulsi a radiofrequenza, chiamata PERFIDI (Parametrically Enabled Relaxation Filters with Double and multiple Inversion), particolarmente utile per lo studio a Risonanza Magnetica Nucleare (NMR) di sistemi che presentino una distribuzione di tempi di rilassamento longitudinale. La categoria di impulsi a radiofrequenza agisce come un filtro, estraendo il segnale che viene generato da componenti del campione, il cui tempo di rilassamento longitudinale giace in un determinato intervallo di valori.
Le varie componenti del segnale vengono filtrate gia' nelle fasi di acquisizione, esaltando la capacita' di discriminazione. Essendo definita parametricamente (con i ritardi tra gli impulsi che agiscono come parametri aggiustabili) la forma funzionale del filtro puo' essere in larga misura controllata dall' operatore dello strumento NMR/MRI
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Mortoniella (Mortoniella) paraenchrysa Sykora 1999
No full textMortoniella (Mortoniella) paraenchrysa Sykora, 1999 Fig. 15 Mortoniella n. sp. 3, Flint 1996: 383 [member of enchrysa subgroup]. Mortoniella paraenchrysa Sykora 1999: 381 [member of enchrysa subgroup]; Blahnik and Holzenthal 2008: 70 [member of bilineata group]; Blahnik and Holzenthal 2011: 63 [member of enchrysa subgroup]. This species is probably most readily diagnosed by its golden color and the form of the inferior appendage, which has an elongate, narrow dorsal projection that is very strongly and almost hemispherically curved. The projection is somewhat similar to that in M. denticulata Sykora, which differs in so many other respects (the separated and angulate ventrolateral projection of segment X, spines on the apex of the dorsal phallic spine, and minutely spined membranous lobes of the endophallic membrane) that it is hardly likely to be confused. Adult —Length of forewing: male 6.4 mm. Forewing with forks I, II, and III present, hind wing with forks II, III, and V. Spur formula 0:4:4. Dorsal side of forewings, head, basal segments of antennae, and legs golden-orange; ventral side of forewings (and apicomarginal setae), hind wings, apices of antennae, and palps dark brownish-black (fuscous). Wing membrane not apparently infuscated. Tibial spurs brownish-black, contrasting with legs. Wing bars absent. Male genitalia —Ventral process of segment VI posteriorly projecting, very short, narrow basally, length about 1½ times width at base. Tergum VIII relatively narrow, subtending ventral margin of segment IX, membranous connection to tergum IX elongate. Segment IX with anterolateral margin rounded and produced in ventral half, posterolateral margin with distinctly angular projection in dorsal half; segment deeply mesally excised dorsally and ventrally, forming lateral lobes, separated dorsomesally by more than ½ width of segment. Tergum X with basal part slightly inflated, distinctly set off from apical part, tergum moderately elongate, lateral margins rounded, ventrolaterally with short acute lateral lobes, each with prominent apical seta; apex of tergum distinctly sclerotized, emarginate, with ventrolateral margins incurved and approaching each other mesally, but separated by distinct gap, apicodorsally with broad U-shaped connection near apex (mesal notch distinct); tergum ventromesally with paired, rounded and sclerotized, ventromesal lobes in basal half, each with short setae. Inferior appendages with short narrow setose dorsolateral lobes and paired ventromesal lobes, each with narrow, strongly hemispherically curved, dorsal process and short acute apicomesal process. Mesal pockets of inferior appendage with very elongate, posteriorly-directed, spine-like, apicoventral projections. Paramere appendages elongate, narrow, slightly widened preapically, apices acute, subequal in length to dorsal phallic spine; fused basal segments of parameres articulating near base of dorsal phallic spine. Phallobase with relatively small rounded, laterally compressed, dorsomesal apodeme. Dorsal phallic spine, as viewed laterally, with dorsal margin curved basally, slightly undulate in middle, and nearly rectilinearly upturned in apical ¼, apex of spine rounded; base of spine narrow, undulately curved and stalk-like, abruptly and very strongly widened on ventral margin in basal ½, forming obtusely angular ventral projection, narrowing apically from projection; spine, as viewed dorsally, somewhat widened in middle, apex rounded. Phallicata with sclerotized basodorsal projection, articulating with angular ventral projection of dorsal phallic spine; phallicata ventrally with elongate, lightly sclerotized, lobes, extending about same length as paramere appendage, lateral margins of lobes subparallel, apices mesally curved. Endophallic membrane with conspicuous, membranously pleated, lateral lobes; phallotremal spines absent.

This species is distinctive in so many respects that it is unlikely to be confused with any other species. Particularly diagnostic is the elongate, arched and separated, ventrolateral lobe of tergum X. Characters shared with other species, but uniquely combined in <i>M. denticulata</i>, include: numerous small spines on the apex of the dorsal phallic spine; minutely spined and projecting lobes on the endophallic membrane; and a narrow, arched dorsolateral projection on the inferior appendage. The latter character is somewhat similar to <i>M. paraenchrysa</i> Sykora, but not as dramatically curved.</p> <p> <i>Adult</i> —Length of forewing: male 4.9-6.0 mm; female 5.8-6.0. Forewing with forks I, II, and III present, hind wing with forks II, III, and V. Spur formula 0:4:4. Overall color of male, including dorsal side of forewings, head, legs, and base of antennae, golden-brown, female slightly darker. Wing membrane of fore- and hind wings distinctly infuscated, more distinctly evident on ventral side of forewings and hind wings, due to short scant setae (of same color as dorsal side of wings). Palps, apices of antennae, and marginal setae of wings dark brown. Tibial spurs dark brown, contrasting with legs. Wings of male without wing bars, of female with indistinct or interrupted white wing bar at anastomosis.</p> <p> <i>Male genitalia</i> —Ventral process of segment VI posteriorly projecting, moderate in length, narrow basally, length about 2 times width at base.

Inferior appendages with moderately elongate narrow, posteriorly recurved, dorsolateral lobes and short acute, paired, apicoventral lobes. Mesal pockets of inferior appendage with elongate, posteriorly directed, spine-like, apicoventral projections. Fused basal segments of parameres articulating near middle of stalklike basal part of dorsal phallic spine, paramere appendages absent. Phallobase with relatively small rounded, laterally compressed, dorsomesal apodeme. Dorsal phallic spine, as viewed laterally, with dorsal margin sinuously undulate, gradually upturned in about apical 1/3, base of spine narrow, stalk-like and sinuously curved, distinctly widened on ventral margin in basal ½, forming acute ventral projection, apical part of spine rather uniformly broad, apex rounded, spine with many small lateral spines in about apical 1/3; spine, as viewed dorsally, slightly widened in middle, apex rounded. Phallicata with sclerotized basodorsal projection, articulating with angular ventral projection of dorsal phallic spine; phallicata ventrally with indistinct, lightly sclerotized, lobes, extending about same length as recurved dorsal lobe of inferior appendages.
