J. death, it is the purpose of this text to comment on and point out the importance of the Commentarii Exegetici in Apocalypsim (Évora. 1603), drawing attention to some of the characteristics which made it a well known work throughoutt Europe
Investigações pós-coloniais: Pepetela e Francisco José Viegas
No full textO texto pretende estudar a produção dos escritores Francisco José Viegas, português, e Pepetela, angolano, procurando observar como, no alvorecer do século XXI, ambos promoveram, em suas obras, o encontro não apenas de temas comuns, mas, principalmente, de estratégias semelhantes, inaugurando o século com narrativas que, de certa forma, representavam uma ruptura com a obra que haviam desenvolvido até então.Palavras-chave: Francisco José Viega; Pepetela; Narrativa policial; Romance pós-colonial.</p

Pterostigma brown. Hindwing hyaline, yellowish. Foreleg dark brown, except fore tibiae yellow on proximal third; mid leg light brown; hind leg yellow, except apex of femur and base of tibia dark brown (Fig. 55). Abdomen dark brown, except upper half of sternite III, dorsal region of sternite IV and V pale yellow and anal tube, pygofer and genital style yellow (Figs 55, 58).</p> <p>Head: frons with median carina present, but weakly marked; lateral carina of frons weakly directed obliquely laterally (Fig. 56); vertex length subequal to the median length of the pronotum in dorsal view (Fig. 57); pedicel approximately 5 times longer than wide and scape conspicuous in anterior view (Fig. 56). Thorax: pronotum with median longitudinal carina present but weakly marked; mesonotum with lateral longitudinal carina present and strongly marked (Fig. 57).

Pygofer narrower in the dorsal half, widening to the ventral half in lateral view, posterior margin concave and without projections (Fig. 59); medioventral process of pygofer conspicuous in lateral view, with posterior margin rounded in ventral view (Fig. 59). Gonostyli approximately the same diameter in lateral view (Fig. 62), apex bifid and divergent apically in dorsal and posterior views (Figs 61, 63). Phallic complex (Figs 64–65): periandrium and aedeagus not distinguished, bearing two subbasal projections with bifid apex, a dorsal, long and robust falciform projection and a ventral, long and slender, almost straight projection; one shorter and slender spine (S1), one elongate comma-like spine (S2) near base. Anal tube concave ventrally, asymmetrical; base of the anal tube very short, approximately 1/3 length of the anal tube extension in lateral view, apex rounded in posterior view (Figs 59–61).</p> <p> <b>Etymology.</b> This species is named after Dr. Augusto Loureiro Henriques from the National Institute of Amazonian Research - INPA, Manaus, Brazil, collector of part of the material of this species, for his relevant contribution to the knowledge to the Brazilian invertebrate fauna.</p> <p> <b>Distribution</b>.

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
