Analysis of species hyper-diversity in the tropical rain forests of Indonesia: the problem of non-observance

The main interest in the assessment of forest species diversity for conservation purposes is in the rare species. The main problem in the tropical rain forests is that most of the species are rare. Assessment of species diversity in the tropical rain forests is therefore often concerned with estimating that which is not observed in recorded samples. Statistical methodology is therefore required to try to estimate the truncated tail of the species frequency distribution, or to estimate the asymptote of species/diversity-area curves. A Horvitz-Thompson estimator of the number of unobserved (“virtual”) species in each species intensity class is proposed. The approach allows a definition of an extended definition of diversity, ( or generalised Renyi entropy). The paper presents a case study from data collected in Jambi, Sumatra, and the “extended diversity measure” is used on the species data.

A last resort

Considers the situations in which the presumption of advancement should apply to gifts given to family members and how this relates to the presumption of a resulting trust, whereby the law presumes that gifts are to be held for the benefit of the donor unless expressed otherwise, with reference to the Privy Council ruling in Antoni v Antoni. Highlights the bias inherent in the presumption of advancement where it operates for gifts given by husbands to wives, but not the other way round. [From Legal Journals Index]

Venetian time and the meander

Argues that the past is necessary to architectural modernity for its self-definition. Goes on to look at Le Corbusier and the past in relation to his revolutionary architectural manifesto, 'Vers une architecture' (1923), and his and Tafuri's views on Venice. Also considers Le Corbusier's 'law of meander' as a strategy for urbanism and his Venice Hospital project
