This essay examines aspects of the serialisation of the novels of William Clark Russell, the greatest late Victorian nautical novelist. Focusing on the treatment of his work by the Edinburgh firm of Messrs Chambers, the article provides an illuminating perspective on market censorship in this period. Drawing on the archives of Chatto & Windus and the literary agent A.P. Watt, it traces the network of relations between author, agent, magazine editor and book publisher, showing how the various components of the serial market operated in the late 1880s and early 1890s.

Undeniably, anticipation plays a crucial role in cognition. By what means, to what extent, and what it achieves remain open questions. In a recent BBS target article, Clark (in press) depicts an integrative model of the brain that builds on hierarchical Bayesian models of neural processing (Rao and Ballard, 1999; Friston, 2005; Brown et al., 2011), and their most recent formulation using the free-energy principle borrowed from thermodynamics (Feldman and Friston, 2010; Friston, 2010; Friston et al., 2010). Hierarchical generative models of cognition, such as those described by Clark, presuppose the manipulation of representations and internal models of the world, in as much detail as is perceptually available. Perhaps surprisingly, Clark acknowledges the existence of a “virtual version of the sensory data” (p. 4), but with no reference to some of the historical debates that shaped cognitive science, related to the storage, manipulation, and retrieval of representations in a cognitive system (Shanahan, 1997), or accounting for the emergence of intentionality within such a system (Searle, 1980; Preston and Bishop, 2002). Instead of demonstrating how this Bayesian framework responds to these foundational questions, Clark describes the structure and the functional properties of an action-oriented, multi-level system that is meant to combine perception, learning, and experience (Niedenthal, 2007).

Transforming the meaning of the term 'guerrilla' which had once meant feud or private warfare, and then irregular war conducted by special forces on behalf of a state or government, the Spanish Guerrilla (part of the Peninsular War) against Napoleon became the model to be emulated by insurgency movements across the world. Even though the term itself continued to be used, even in Spanish, for special operations, in henceforth became imbued with an ideological dimension, which is how it would be used especially in the 20th century.

Difficulties concerning the taxonomy of stauromedusae are long known, and there is a clear need for taxonomic revision of the genus Haliclystus, as well as the reevaluation of some species. Haliclystus antarcticus Pfeffer, 1889 is recorded from Admiralty Bay, King George Island, Antarctic Peninsula. Due to the lack of detailed information on this species, we provide a redescription, presenting new data on the cnidome, morphometry, geographical distribution and intraspecific variation. Based on these characters, we propose that our specimens and Haliclystus auricula from Chile and Argentina are synonymous and should be classified as H. antarcticus. We also review the worldwide distribution of the genus Haliclystus Clark, 1863 and discuss taxonomic issues, concluding that some characters traditionally used in the taxonomy of the group should be used cautiously.

A presente investigação desenvolve um estudo sobre o percurso histórico das elites municipais do concelho da Ponta do Sol, entre 1878 e 1886, inserindo-as no contexto global das regras definidas pelo suporte legislativo do Código Administrativo de 1878, bem como no espaço socioeconómico, onde detiveram um papel preponderante e decisivo nos destinos do mesmo. Esta dissertação analisa a realidade local na construção de uma identidade municipal, aplicando métodos e técnicas de investigação histórica. A partir de fontes manuscritas, como os recenseamentos eleitorais, este trabalho faz a inventariação do corpus eleitoral do concelho supramencionado, isto é, a caracterização socioeconómica dos cidadãos habilitados a votar (eleitores) e dos elegíveis, culminando nos eleitos para os cargos municipais. De igual modo, procurou conhecer as áreas de intervenção da Câmara Municipal da Ponta do Sol e respetivos espaços de atuação da elite dirigente camarária.

Reference intervals for haematologic and total plasma proteins profiles were determined for 11 physically restrained adult grey-brocket deer. Erythrocytic alterations, as discrete to moderate poikilocytosis, were observed in all animals. Red and white blood cells counts were determined by manual methodology. Obtained erythron and leukon values were slightly higher than previous reports. Statistical difference was not demonstrated between stags and hinds. No previous studies reported blood values for captive grey-brocket deer obtained by manual methods. Also, the authors suggest that future studies on deer haematology should be focused on technique evaluation and improvement, considering the unusual erythrocytic morphology.

Morphological aspects of spermatozoa in marine animals have been used in recent decades as phylogenetic criteria (spermiotaxonomy). This paper presents ultrastructural descriptions of the spermatozoa from Uca maracoani, U. thayeri, and U. vocator. A small portion of the vas deferens of each species was examined under the transmission and scanning electron microscopy. The ultrastructural analysis showed that each spermatophore consists of a varying number of spermatozoa embedded in a dense fibrillar matrix surrounded by a membrane. The spermatozoa of U. maracoani, U. thayeri, and U. vocator are typical of brachyurans. The Voluminous acrosome is characterized by three different layers. The postero-lateral surface of the acrosome is cupped by the reduced cytoplasm, and the anterior surface is covered by the operculum. The perforatorium consists of coiled, helicoidal membranous tubules and is continuous with the cytoplasm. The nucleus is composed by uncondensed chromatin and presents several lateral arms distributed over the entire equatorial plane of the cell. The presence of the apical button is a well defined character among all species of the genus Uca, but in U. thayeri it was not observed. The accessory opercular ring can be found in the three studied species, but in distinct development degree-Two centrioles were detected in U. thayeri and U. vocator, but only one was found in U. maracoani. The presence of centrioles in the mature spermatozoa is the first account for the genus Uca upto-date. Considering the ultrastructure of the spermatozoa of U. maracoani, U. thayeri, and U. vocator, we suggest that these three species partially follow the morphological patterns previously described in other Thoracotremata brachyurans. The absence of the apical button in U. thayeri spermatozoa may represent an evolutionary novelty in the genus Uca. (C) 2007 Elsevier Ltd. All rights reserved.
