New record of predatory ladybird beetle (Coleoptera, Coccinellidae) feeding on extrafloral nectaries
Almeida, Lúcia M.;Corrêa, Geovan H.;Giorgi, José A.;Grossi, Paschoal C.;
Revista Brasileira de Entomologia , 2011, DOI: 10.1590/S0085-56262011005000028
Abstract: new record of predatory ladybird beetle (coleoptera, coccinellidae) feeding on extrafloral nectaries. feeding by exoplectra miniata (germar) on extrafloral nectaries of inga edulis mart. was observed in nova friburgo, rio de janeiro, brazil. this is the first record of this behavior for exoplectrini.
Revision of the genus Harpasus Mulsant (Coleoptera, Coccinellidae, Chilocorini)
Corrêa, Geovan H.;Almeida, Lúcia M.;
Revista Brasileira de Entomologia , 2010, DOI: 10.1590/S0085-56262010000300002
Abstract: harpasus mulsant, 1850 was studied based on the morphology of the exoskeleton and genitalia. the type material of harpasus aureus almeida & carvalho, 2006, h. quadrifolium gonzález, corrêa & almeida, 2008 and a homotype of h. zonatus (mulsant, 1850) were examined. the lectotype of h. eversmanni (mulsant, 1850) was designated and two new species were described, harpasus unifasciatus sp. nov. (teresópolis, rj, brazil) and harpasus ferrugineus sp. nov. (puerto carre?o, vichada, colombia). herein a diagnosis for the genus and its seven species, identification key and information about biological aspects are presented.
Revis?o das espécies brasileiras do gênero Exoplectra Chevrolat (Coleoptera, Coccinellidae, Exoplectrinae, Exoplectrini)
Costa, Ana V.;Almeida, Lúcia M.;Corrêa, Geovan H.;
Revista Brasileira de Entomologia , 2008, DOI: 10.1590/S0085-56262008000300010
Abstract: the brazilian species of exoplectra chevrolat, 1844, based on the morphological analysis of external characters and genitalia, are revised. among the 37 species in the genera, 14 brazilian species were analysed, including three new species. it was studied the type material of nine of them. the lectotypes of e. angustifrons weise, 1895, e. calcarata (germar, 1824), e. coccinea (fabricius, 1801) and e. miniata (germar, 1824) are designated. exoplectra companyoi mulsant, 1850 is revalidated; e. aenea (fabricius, 1801), e. bernardinensis brèthes, 1925, e. impotens mulsant, 1850, e. luteicornis mulsant, 1850 and e. irregularis (crotch, 1874) are provisionally removed from the genus. two new species from brazil are proposed: e. columba sp. nov., from paraná and e. bimaculata sp. nov., from amazonas. dicotomic key for species is presented as well as pictures and illustrations for the main structures used in the identification.
A Note on the Guignard Constraint Qualification and the Guignard Regularity Condition in Vector Optimization  [PDF]
Giorgio Giorgi
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.44101
Abstract:

Some remarks are made on the use of the Abadie constraint qualification, the Guignard constraint qualifications and the Guignard regularity condition in obtaining weak and strong Kuhn-Tucker type optimality conditions in differentiable vector optimization problems.

Giorgio Giorgi
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.58114
Abstract:

We give a short and easy proof of the characterization of differentiable quasiconvex functions.

Difficulties encountered in the application of the phenomenological method in the social sciences
Giorgi,Amedeo;
Análise Psicológica , 2006,
Abstract: while it is heartening to see that more researchers in the field of the social sciences are using some version of the phenomenological method, it is also disappointing to see that very often some of the steps employed do not always follow phenomenological logic. in this article several dissertations are reviewed in order to point out some of the difficulties that are encountered in attempting to use some version of the phenomenolo-gical method. difficulties encountered centered on the phenomenological reduction, the use of imaginative variation and the feedback to subjects.
