Commentary on Tonson v. Collins (1762)

Significant case in which the arguments for and against the existence of copyright at common law were extensively debated for the first time before the Court of King's Bench. Both William Blackstone (author of Commentaries Upon the Laws of England, and one of the judges to hold in favour of the common law right in Donaldson v. Becket (uk_1774)) and Joseph Yates (who would later provide the dissenting opinion in Millar v. Taylor (uk_1769)) appeared on behalf of the plaintiff and the defendant respectively.

Commentary on An Enquiry into the Nature and Origin of Literary Property (1762)

One of a number of published commentaries contributing to the mid-eighteenth century debate concerning the nature of literary property. The author of An Enquiry sought to repudiate the concept of a natural authorial property right existing at common law. In so doing, he specifically engaged with various aspects of William Warburton's earlier commentary (see: uk_1747), as well as presenting arguments that drew upon the nature of property in general, the differences between the right claimed by proponents of the common law right and other acknowledged incorporeal properties, the similarities between patents and copyright, the history of literary property, the experience of other jurisdictions (drawing upon Venice in particular), and the consequences that would follow from conceding the existence of a perpetual right both for authors in particular and society in general. This commentary, in turn, drew its own response in the guise of A Vindication of the Exclusive Rights of Authors, to their own work (1762).

The Drama of History: Representation and Revolutionaries in Haitian Theater, 1818-1907

Since the beginning of the Haitian theatrical tradition there has been an ineluctable dedication to the representation of Haitian history on stage. Given the rich theatrical archive about Haiti throughout the world, this study considers operas and plays written solely by Haitian playwrights. By delving into the works of Juste Chanlatte, Massillon Coicou, and Vendenesse Ducasse this study proposes a re-reading of Haitian theater that considers the stage as an innovative site for contesting negative and clichéd representations of the Haitian Revolution and its revolutionary leadership. A genre long mired in accusations of mimicking European literary forms, this study proposes a reevaluation of Haitian theater and its literary origins.

Growth of the speckled swimming crab, Arenaeus cribrarius (Lamarck, 1818) (Crustacea, Brachyura, Portunidae), in Ubatuba (SP), Brazil

A total of 2629 individuals of Arenaeus cribrarius (1293 males and 1336 females) were captured in Ubatuba (SP), from August 1996 to July 1997. Individuals were distributed in 5 mm size class carapace width (CW), to verify sex-specific growth-age equations. The Von Bertalanffy model was chosen to determine the growth rate and expressed by CW=120.52[1-e(-1.80t)] for males and CW=100.81[1-e(-1.60t)] for females. The age estimated for the first juvenile stage (t(o)) was 6.1 and 8.3 days for males and females, respectively. The maximum age determined was 1.8 years for males and 2 years for females, which correspond to a maximum size of 115.8 and 96.7 mm, respectively. The maximum size (CWmax) estimated using 95% of asymptotic size was 114.5 mm for males and 95.8 mm for females. Males have a precocious sexual maturity (5 months) when compared to females (6.8 months). The growth rate and size of A. cribrarius are higher than other portunid species, with great interest for aquaculture.

Elysia timida (Risso, 1818) three decades of research

Elysia timida (Risso, 1818) three decades of research.— During the last 30 years, studies on Elysia timida (Risso, 1818) have addressed various aspects related to food sources, photosynthetic efficiency of kleptoplasts, population genetics, chemical ecology and reproductive biology, both in the Mediterranean Sea and in the Mar Menor coastal lagoon. E. timida shows a strong specific interaction with Acetabularia acetabulum, retaining functional chloroplasts for at least 45 days and obtaining extra energy in periods when food resources are scarce. It shows control of parapodia, avoiding pigment photodestruction under oversaturated light conditions. The chemical ecological relationships established between E. timida and its potential predator fish, Thalassoma pavo, have also been evaluated, and it has been found that that the extracts of the mollusc contain repellent and unpalatable polypropionate compounds. Population genetics has demonstrated the genetic divergence between populations showing high and significant values of FST and genetic distances, and at least six privative alleles that are not shared with Mediterranean populations have been detected in lagoon populations. This sacoglossan is a poecilogonic species, and its lagoon populations show a greater reproductive output than Mediterranean populations; they produce a greater number of egg masses and embyros per individual, and the capsules have a wider diameter.

Evaluación biológica poblacional de macha (Mesodesma donacium, Lamarck 1818) en la provincia de Islay, Arequipa. Febrero 2015

La evaluación se realizó entre el 20 y 26 de febrero 2015, el área de distribución de la macha comprendió la playa entre punta Corio y Sombrero Chico en la provincia de Islay; no se registró entre el Boquerón y La Ensenada. La mayor concentración se observó entre Las Cuevas y El Tablón (área de repoblamiento de Islay). La densidad relativa de las estaciones/transectos varió entre 0 y 20,39 ejem/m2. El área efectiva de distribución se calculó en 1´413.514 m2, se estimó abundancia en 7´722.393 ejemplares y biomasa total 147,58 t. Se analizó biométricamente 2.612 ejemplares, la talla varió entre 26 y 90 mm de longitud valvar (LV), con moda principal en 62 mm y secundaria en 76 mm, la longitud promedio fue 59,17 mm, el 89,43% estuvo debajo de la Talla Mínima de Captura (TCM= 70 mm). Los perfiles medios de playa fueron de pendiente suave que varió entre 1,00° y 1,72°; en el Sector sur (Punta de Bombón) se observó playas intermedias acercándose a los límites de playas disipativas (Ω entre 3,14 y 5,92), en el Sector norte (Dean Valdivia - Mejía) se observaron playas intermedias - disipativas (Ω entre 4,53 y 5,22). La temperatura superficial del mar varió entre 16,4 y 21,0 °C, promedio 18,2±0,02 °C. En el análisis del plancton, entre El Molle y Cardones y El Conto y Mejía, se observó larvas D y umbonadas con características similares a Mesodesma donacium.

Growth, parasitic infection and hematology in Colossoma macropomum Cuvier, 1818 fed diets containing Allium sativum.

The aim of this study was to investigate the effects of a dietary Allium sativum (garlic) addition on growth, parasite infestation and blood parameters in Colossoma macropomum (tambaqui) using 12 net-cages (1 m3).
