By macroscopic and microscopic dorsal side observation, it was noted that the IX and X segments of two species each of Panstrongylus and Triatoma terminate in an elongated way, whereas they terminate abruptly in the two species of Rhodnius. Scanning observation of the dorsal, ventral, lateral and posterior sides of the female genitalia of Panstrongylus herreri, Panstrongylus megistus, Rhodnius ...

Previous phonotaxis experiments in the túngara frog, Physalaemus pustulosus, indicated a permissiveness in female preference that allows sexually selected complex call characters to be replaced with various alternative characters. Although they prefer complex to simple calls, females as a group did not discriminate between several alternative complex characters appended to the simple conspecifi...

OBJECTIVES To analyse the injury-related content of children's television programmes preferred by boys and by girls, and to determine whether there are more televised models of unsafe behaviour in programmes preferred by boys. METHODS Parents of 4-11-year-old children identified their children's favourite television programmes. Content analysis of 120 episodes of children's favourite programm...

Cranial features (development, individual variation, and sexual dimorphism) were examined from the 23 metrical characters and 2 nonmetrical characters (the degree of closure of the 9 cranial sutures and the presence of sagittal crest) in the two spotted seal specimen groups at the Nemuro Strait, Hokkaido. One specimen group was incidentally taken in the salmon trap nets between 1982 and 1983 (n...

A content analysis was conducted to examine sexual consequences on teen programming. The sample consisted of prime-time television dramas that featured characters between the ages of 12 and 22 years. Two major goals guided the study. First, the types of sexual consequences in teen programming were investigated. Results showed that emotional and social consequences far outnumbered physical conse...

This paper offers a Derridian reading of D.H. Lawrence’s novel Women in Love, with excerpts from the novel’s prequel The Rainbow. Through Derrida’s ideas of difference and the imaginary origin, I explore the relationship between female reproductive potential and representation as means to a female sexual power, which Lawrence’s men attempt to destroy and subvert. By attacking realms of represen...

The systematics of the freshwater crustacean genus Bosmina Baird, 1845 (Anomopoda: Bosminidae) is notoriously confused. Part of the problem stems from a lack of characters in this cyclic parthenogen. We aimed to remedy this problem by scoring male morphological characters (previously described in just a few species), and by estimating molecular phylogenies. More specifically, the goals of this ...
