1. Entre racializações: Oliver C. Cox e a sociologia
Resumo Oliver Cromwell Cox foi um sociólogo negro de Trinidad e Tobago que passou a maior parte de sua vida pessoal e intelectual nos Estados Unidos. Neste país, o caráter heterodoxo de suas críticas à sociologia de seu tempo lançaram sobre sua obra um silêncio que durou décadas. Em tempos recentes, porém, o crescente interesse por sua obra trouxe �

2. Gut anatomy of the worker caste of Neotropical genera Cylindrotermes Holmgren and Hoplotermes Light (Infraorder Isoptera, Termitidae)
ABSTRACT Studies over the last six decades have shown that the gut anatomy of the termite worker caste provides a valuable set of taxonomic characters. However, the gut anatomy of most American termitine taxa is still little known. This study investigated the anatomy of the worker gut of the Neotropical termitine genera Cylindrotermes Holmgren and Hoploterme

3. Aspects of Hybridism in Joseph Conrad’s Almayer’s Folly and Heart of Darkness
Abstract In the light of concepts put forth by cultural theorists like Homi Bhabha, Edward Said and Clifford Geertz, among others, this essay discusses Joseph Conrad’s novels Almayer’s Folly and Heart of Darkness as stagings of the conflicts inherent in the syncretic nature of all culture. In the first novel, the protagonist’s daughter, Nina, the offsp

4. Variation of cuticular chemical compounds in three species of Mischocyttarus (Hymenoptera: Vespidae) eusocial wasps
Abstract The social wasps have a remarkable system of organization in which chemical communication mediate different behavioral interactions. Among the compounds involved in this process, cuticular hydrocarbons are considered the main signals for nestmate recognition, caste differentiation, and fertility communication. The aims of this study were to describe

5. Epigenetic modifications and their relation to caste and sex determination and adult division of labor in the stingless bee Melipona scutellaris
Abstract Stingless bees of the genus Melipona, have long been considered an enigmatic case among social insects for their mode of caste determination, where in addition to larval food type and quantity, the genotype also has a saying, as proposed over 50 years ago by Warwick E. Kerr. Several attempts have since tried to test his Mendelian two-loci/two-allele

6. Exploring Past Myths through Giambattista Vico and Jyotiba Phule
Abstract In this article, I examine the writings of the 18th-century Italian thinker Giambattista Vico and the 19th-century Indian thinker/social reformer Jyotiba Phule about myths, temporality, and the past. Both these thinkers turned to historicising myths in order to engage with debates in the present. Both viewed myths as reflecting social relations of

7. Insights into the dynamics of hind leg development in honey bee (Apis mellifera L.) queen and worker larvae - A morphology/differential gene expression analysis
Phenotypic plasticity is a hallmark of the caste systems of social insects, expressed in their life history and morphological traits. These are best studied in bees. In their co-evolution with angiosperm plants, the females of corbiculate bees have acquired a specialized structure on their hind legs for collecting pollen. In the highly eusocial bees (Apini a

8. Terpenos em cupins do gênero Nasutitermes (Isoptera, Termitidae, Nasutitermitinae)
The chemical composition of the front gland of termites has been studied for over 40 years. The genus Nasutitermes, considered the most evolved of the Termitidae family, has a peculiarity that sets it apart from the others: a caste of soldiers that carry a terpenic mixture used in defense. This secretion is formed by mono, sesqui and diterpenes from trinervi

9. Caste polymorphism of apterous line of the Neotropical termite Nasutitermes corniger (Motschulsky) (Isoptera, Termitidae)
Termite societies are structured by individuals that can be grouped into castes and instars. The development of these instars in most species occurs in irregular patterns and sometimes is distinguished subcastes in physical systems that originate polymorphic soldiers and workers. In this study, we characterized the morphological diversity of castes of aptero

10. Entre o arado e o celular, a Índia : identidade e contradição na indústria tecnológica / Between the plow and the mobile phone, India : identity and contradictions in the technological industry
A Índia possui uma indústria de Tecnologias da Informação e Comunicação (TICs) de alcance global. Esta dissertação busca entender a trajetória do sucesso indiano por meio de uma análise de seus protagonistas, que são membros de uma elite que está em contato intenso com o Ocidente desde os tempos em que o país era uma colônia britânica, ao mesm

11. Ocorrência natural de sexuados, produção in vitro de rainhas e multiplicação de colônias em Tetragonisca augustula (Hymenoptera, Apidae, Meliponini) / Natural occurrence of sexuals, production in vitro of queens and colony multiplication in Tetragonisca angustula (Hymenoptera, Apidae, Meliponini).
Com o avanço da meliponicultura, a utilização das abelhas sem ferrão, assim como de seus subprodutos, tem abrangido novas áreas, como a polinização de culturas agrícolas. Assim, a demanda pelo aumento do número de colônias tem sido constante, porém devido ao pouco conhecimento sobre a biologia reprodutiva dessas abelhas, há dificuldade de produç

12. An adaptive view of caste differentiation in the neotropical wasp Polybia (Trichothorax) sericea Olivier (Hymenoptera: Vespidae)
The tribe Epiponini comprehends the swarm-founding Neotropical wasps, with several species endemic to Brazil, which are extremely important in studies of social evolution of wasps. The Epiponini diverge in several ways from the definitions of high eusociality, since caste syndromes range from species without morphological caste differentiation to those with
