Variations on the Author
No full text“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

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Assembly of the Inner Perivitelline Layer, a Homo log of the Mammalian Zona Pellucida: An Immunohistochemical and Ultrastructural Study
No full textThe avian inner perivitelline layer (IPVL), a homologous structure to the mammalian zona pellucida, is deposited between the granulosa cells and the oocyte cell membrane during folliculogenesis. The glycoprotein meshwork of the IPVL forms a 3-dimensional matrix and possesses important functions in the fertilization process: it contributes to the binding of avian spermatozoa to the oocyte and induces acrosomal exocytosis. In contrast to the zona pellucida of mammals, the IPVL does not prevent the physiological polyspermy found in birds. Previous studies have shown that in the Japanese quail (Cotumix japonica) at least 5 glycoproteins are constituents of the IPVL (ZP1, ZP2, ZP3, ZP4, and ZPD). In this study, we investigated the spatiotennporal assembly pattern of the IPVL during folliculogenesis using immunohistochemical and ultrastructural methods. The obtained results clearly show that these glycoproteins are incorporated into the IPVL at distinct points during follicular development, supporting the hypothesis that ZP2 and ZP4 form a type of prematrix into which ZP1, ZP3, and ZPD are integrated at a later stage of development.

Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either

Oioceros atropatenes Rodler & Weithofer 1890
No full textOioceros atropatenes Rodler & Weithofer, 1890 (Fig. 7E, F) LOCALITY. — Quarry 1, Ivand district, north of Tabriz, Iran. MATERIAL EXAMINED. — Left horn-core (HMNH-IV 200; Fig. 7E, F), right mandible with p4-m3 (HMNH-IV 67; Table 3), right mandible with broken m2 and complete m3 (HMNH-IV 69; Table 3). DESCRIPTION The horn-core specimen is partly broken at the base and the tip. The antero-posterior diameter cannot be measured precisely due to the basal missing part on both the anterior and posterior sides. However, we estimate that it exceeds 17 mm. The medio- A M1 M2 M3 M4 M6 M7 M14 M15 M23 M25 M30 M31 M32 M33 lateral diameter is 17.4 mm. The DAP and DT at 5 cm above the base are 12.7 mm and 10.9 mm, respectively. The total preserved length is 75 mm from the pedicle. By the preserved part of the orbit and remnant of the frontal, the horn-core is located above the posterior part of the orbit, tilted slightly backwards with a weak curvature. The horn-core is slender with a roughly oval cross section. The antero-posterior and transverse diameters diminish slowly from the base upwards. There are two weak keels, one starting from the antero-lateral side, and the other from the postero-lateral side. These two keels enclose a slightly convex outer surface and a more rounded inner surface. The keels spiral clock- wise roughly one gyre from the base to the tip by estimation. There is also a postcornual fossa. p4 is long and narrow. The paraconid is not separated from the parastylid. The anterior valley is wide. The metaconid is situated posterior to the protoconid. The entoconid is close to the entostylid. A wide and shallow valley separates the protoconid from the hypoconid.m1 is well worn. The parastylid is developed, and well separated from the metaconid. There is no goat fold, thus rendering the anterior border much narrower. The lingual wall is flat with weak metastylids. The entostylid is larger. There is a large basal pillar between the protoconid and the metaconid. m2 is very similar in morphology to m1, except for its larger, more convex lingual wall, and lower basal pillar. The parastylid on m3 is more pronounced and well separated from the metaconid. The basal pillar is small and low. The hypoconulid is large and postero-labially offset. COMPARISON Based on the small size, insertion above the posterior part of orbit, the clockwise torsion on the left horn-core from the base, and two keels, the horn-core IV200 from Ivand locality can readily be assigned to the genus Oioceros (type species Antelope rothii Wagner, 1857 from Pikermi, Greece) (Gaillard 1902). Since then, numerous species were included or assigned to this genus. De Mecquenem (1924) recognized three species from Maragheh: O. rothii (Wagner, 1857), O. atropatenes and O. boulei Mecquenem, 1924. Heintz (1963) synonymized O. boulei with O. atropatenes based on his detailed description and comparison. Roussiakis (2003) recently described in detail an almost complete skull with mandibles of Oioceros rothii from Pikermi and reviewed the generic status. Besides the type species, he listed only Oioceros atropatenes in the genus. The present specimen is smaller and less laterally compressed than Oioceros rothii from Pikermi. The main keel is much weaker and the upper part of the horn-core diverges less. The size falls into the variation of Oioceros atropatenes from Maragheh, Iran (Heintz 1963). The morphology of the horn-core is also consistent with those from Maragheh. Hence, the horn-core specimen can be assigned to Oioceros atropatenes.Published as part of Ataabadi, Majid Mirzaie, Mohammadalizadeh, Jafar, Zhang, Zhaoqun, Watabe, Mahito, Kaakinen, Anu & Fortelius, Mikael, 2011, Late Miocene large mammals from Ivand (Northwestern Iran), pp. 709-728 in Geodiversitas 33 (4) on pages 718-720, DOI: 10.5252/g2011n4a7, http://zenodo.org/record/459712
Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
No full textThe authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics
Sous-facteurs de L(F∞) d'indice 4cos2π/n,n≥3
No full textLet Q be a factor of type II1, λ a number in the Jones discrete series {4cosπ/m:m≥3}, and {ei} the Jones projections associated with λ. Denote by A2n and A1n the finite-dimensional von Neumann algebras generated, respectively, by {1,e2,⋯,en} and {1,e1,⋯,en}, with the corresponding traces. The author shows that, for n sufficiently large, the index of the inclusion An=(Q⊗A2n)∗A2nA1n⊂(Q⊗A2n+1)∗A2n+1A1n+1=An+1 is equal to λ (here ∗ denotes the reduced, amalgamated free product of the algebras in question). Using the random matrix model of Voiculescu, he proves that if Q is the von Neumann algebra L(F∞) of the free group with infinitely many generators, then An is isomorphic to L(F∞).
The two facts together imply the existence, for any λ in the Jones discrete series, of an irreducible subfactor of L(F∞) of index λ. This constitutes the first example of a nonhyperfinite, non-Γ II1 factor such that its Jones invariant is fully computable (the existence of nonirreducible subfactors of L(F∞) for any index ≥4 is a simple consequence of known results)
