Calling behaviour and evaluation of sex pheromone glands extract of Neoleucinodes elegantalis Guenée (Lepidoptera: Crambidae) in wind tunnel
Eiras, álvaro E.;
Anais da Sociedade Entomológica do Brasil , 2000, DOI: 10.1590/S0301-80592000000300007
Abstract: adult emergence and mating behavior of neoleucinodes elegantalis guenée were studied under laboratory conditions (23 ± 1°c, 12 h photophase and 70% rh). adult emergence occurred only at scotophase period. female began to emerge from the 1st hour to 8th hour with a peak occurring at 4th hour of scotophase. male showed similar trend, but emerging from 2nd to 11th with a peak also at 4th hour of scotophase. mating was preceded by wing vibration in the male prior to and during walking approach. mating occurred only during the scotophase period between the 4th and 10th hour of scotophase, with the peak occurring at the 7th hour. newly emerged n. elegantalis couples rarely mated (2.8%) whereas 48 and 96 h old couples mated 26.3% and 27.5% respectively. glands extracts from abdominal tips of 48-72 h virgin female moths evaluated in a wind tunnel were more attractive than virgin females.

Calibration and evaluation of field cage for oviposition study with Aedes (Stegomyia) aegypti female (L.) (Diptera: Culicidae)
Roque, Rosemary A.;Eiras, álvaro E.;
Neotropical Entomology , 2008, DOI: 10.1590/S1519-566X2008000400018
Abstract: differences among results gathered from insect behavior studies conducted in laboratory and field situations are due to ambient variables that differ greatly between both environments. in laboratory studies the environmental conditions can be controlled whereas in field temperature, humidity and air velocity vary uncontrollably. the objective of this study was to calibrate and evaluate an experimental area (field cage) (14 x 7 x 3.5 m) subdivided into eight test cages (2.5 x 2.5 x 2 m) for use in behavioral oviposition tests of aedes aegypti (l.) mosquitoes for developing a new methodology to assess attractants and oviposition traps. test cage calibration involved: (1) minimal experiment duration tests; (2) optimal female release number per traps test and (3) trap placement tests. all tests used gravid a. aegypti females; 3-4 days post blood meal and the sticky trap mosquitrap? to catch adults. ninety percent of the females released were recaptured 2h after the beginning of the experiment, and this allowed up to 32 test repetitions/day to be conducted in the field cage. the minimum number of females necessary to conduct statistical analyses was 20 females/trap/test per cage. no significant difference was found in the behavioral response of gravid females to four different trap positions within test cages. field trapping results with attractant were similar to those in the field cage. therefore, the field cage could replace field trapping for evaluating at least mosquito traps and oviposition attractants for a. aegypti.
Esquizofrenia, genética, epigênesis, ambiente: uma revis?o sistemática das hipóteses etiológicas unificadas e do perfil genética; e um novo algoritmo para o tratamento dos achados principais
Machado Dias,álvaro; Luiz Rodrigues,E Avelino;

Abstract: context: schizophrenia is a highly complex syndrome, related to genes, and to non-genetic risk factors. famous epidemiological studies reported its presence among all cultures and geographic regions. in that sense, unified etiological hypothesis face the challenge to both present experimental data, and to show that the findings may cope with the syndrome?s universal profile. objectives: systematically review the most prominent unified etiological hypothesis, as much as the semantic distribution of genetic findings (under up to date data mining techniques), and propose a new model, based on the dynamic effects of epigenics over genetic activation in both neurodevelopment and early adulthood. results: in general, unified etiological hypothesis contradict the main genetic findings (which suggest that schizophrenias? genes are mostly associated with neurotransmitter profiles, like d-1 and the glutamate-nmda cascade); also in general, genetic findings are spread all over the genome (as we reveal with a topological map of the 3519 studies on the matter). the key for this conundrum may be represented by the association between the perspective that each polymorphism associated with schizophrenia represents a statistical risk factor (e.g. increasing the risk of developmental instability) while epigenetic molecular cascades and environmental factors considerably influence this picture, affecting genetic activation within critical periods.
A moralidade do abuso sexual intrafamiliar em menores
Morales,álvaro E.; Schramm,Fermin R.;
Ciência & Saúde Coletiva , 2002, DOI: 10.1590/S1413-81232002000200007
Abstract: this article analyses the moral character of sexual abuse against minors taking into consideration the characteristics of the victim and its family environment, as well as the process itself, from when the fact occurred until it was reported to the authorities by relatives and acquaintances, the care provided by the state institucional organs to both the victim and its family members. also, the probatory means used by the judging authorities during the trial of the probable aggressor. the authors discuss the ethical aspects involved in the dynamics of child sexual abuse within the family based on some principles, such as self-determination, justice, equality, equity, free and clear consent, no harmfulness/kindness, among others.
Investigación del Trastorno Formal del Pensamiento en la esquizofrenia: una mirada crítica
Barrera,álvaro; Berrios,Germán E.;
Revista de la Asociación Espa?ola de Neuropsiquiatría , 2001, DOI: 10.4321/S0211-57352001000300003
Abstract: recent research upon the group of "mental symptoms" called formal thought disorder in schizophrenia is reviewed. assumptions concerning their ontological and epistemological status are criticized as the key factors hindering progress for understanding the phenomena.
Violência urbana: um problema social
Gullo, álvaro de Aquino e Silva;
Tempo Social , 1998, DOI: 10.1590/S0103-20701998000100007
Abstract: this article contains some reflections on how social violence expresses itself. these reflections, presented in former moments as lectures, public debates and at a congress, have been gathered under the title of urban violence because they all try to comprehend everyday violence as a problem of urban society. based on the lectures i have formulated the first part of this article, which deals with a conception taken from social anthropology: the characterization of violence in rural society under the perspective of structural marginality, in order to explain the genesis of this problem in the actual social class society. the debates, that took place because of traumatic happenings related to the police apparatus, have brought about a discussion of the causes of violence inherent to the performance of the institutional functions' of military and civil police. the last part of this article is the result of my taking part in a congress organized in order to debate the new brazilian traffic code. it takes into account the role and, particularly, the meaning of the social symbols divulged by the mass media as aspects responsible for the increment of traffic violence.
Las víctimas en el nuevo sistema procesal acusatorio y su reconocimiento por la corte Constitucional

Prolegómenos. Derechos y Valores , 2006,
Abstract: El sistema de protección a la víctima en el nuevo ordenamiento procesal colombiano, es decir, en el sistema acusatorio, derivado del Acto Legislativo 003 del 19 de diciembre de 2003, ha suscitado un importante debate académico frente a su implementación y desarrollo en la Ley 906 de 2004. Un significativo avance en materia de víctimas en nuestro país se presentó con la Sentencia C-228 de 2002 de la Corte Constitucional, en el sentido de reconocer que la víctima o perjudicado con un delito no solo tiene derecho a la reparación económica de los perjuicios, como venía ocurriendo frente a la parte civil, sino que, además tiene derecho a que a través del proceso penal se establezca la verdad y se haga justicia.
