Nick Joaquinâs CĂĄndidoâs Apocalypse: Re-imagining the Gothic in a Postcolonial Philippines
In this context, this paper explores the idea of the Gothic in Joaquinâs writing and how it relates to Joaquin being the âmost original voice in postcolonial Philippine writing.â In 1972, the University of Queensland Press featured Joaquinâs works in its Asian and Pacific writing series. This ânewâ collection, Tropical Gothic (1972), contained his significant early works published in Prose and Poems (1952) plus his novellas. This collectionâs title highlights a specific aspect of Joaquinâs writing, that of his propensity to use Gothic tropes such as the blending of the real and the fantastic, or the tragic and the comic, as shown in most of the stories in the collection. In particular, I examine how his novella (CĂĄndidoâs Apocalypse) interrogates the neurosis of the nationâa disconnection from the past and its repercussions on the present/future of the Philippines
Rockonomics: The Economics of Popular Music
This paper considers economic issues and trends in the rock and roll industry, broadly defined. The analysis focuses on concert revenues, the main source of performers ' income. Issues considered include: price measurement; concert price acceleration in the 1990s; the increased concentration of revenue among performers; reasons for the secondary ticket market; methods for ranking performers; copyright protection; and technological change.
Electronic structure of the compound from ab initio local interactions
We used fully correlated ab initio calculations to determine the effective
parameters of Hubbard and t - J models for the thermoelectric misfit compound
. As for the family the Fermi level orbitals
are the orbitals of the cobalt atoms ; the being always lower
in energy by more than 240\,meV. The electron correlation is found very large
as well as the parameters fluctuations as a function of the
structural modulation. The main consequences are a partial electrons
localization and a fluctuation of the in-plane magnetic exchange from AFM to
FM. The behavior of the Seebeck coefficient as a function of temperature is
discussed in view of the ab initio results, as well as the 496\,K phase
transition
Evaluating Maximum Likelihood Estimation Methods to Determine the Hurst Coefficient
A maximum likelihood estimation method implemented in S-PLUS (S-MLE) to estimate the Hurst coefficient (H) is evaluated. The Hurst coefficient, with 0.5\u3cHS-MLE was developed to estimate H for fractionally differenced (fd) processes. However, in practice it is difficult to distinguish between fd processes and fractional Gaussian noise (fGn) processes. Thus, the method is evaluated for estimating H for both fd and fGn processes. S-MLE gave biased results of H for fGn processes of any length and for fd processes of lengths less than 210. A modified method is proposed to correct for this bias. It gives reliable estimates of H for both fd and fGn processes of length greater than or equal to 211
Turbulent mixing at a stable density interface : the variation of the buoyancy fluxâgradient relation
Experiments conducted on mixing across a stable density interface in a turbulent TaylorâCouette flow show, for the first time, experimental evidence of an increase in mixing efficiency at large Richardson numbers. With increasing buoyancy gradient the buoyancy flux first passes a maximum, then decreases and at large values of the buoyancy gradient the flux increases again. Thus, the curve of buoyancy flux versus buoyancy gradient tends to be N-shaped (rather than simply bell shaped), a behaviour suggested by the model of Balmforth et al. (J. Fluid Mech. vol. 428, 1998, p. 349). The increase in mixing efficiency at large Richardson numbers is attributed to a scale separation of the eddies active in mixing at the interface; when the buoyancy gradient is large mean kinetic energy is injected at scales much smaller than the eddy size fixed by the gap width, thus decreasing the eddy turnover time. Observations show that there is no noticeable change in interface thickness when the mixing efficiency increases; it is the mixing mechanism that changes. The curves of buoyancy flux versus buoyancy gradient also show a large variability for identical experimental conditions. These variations occur at time scales one to two orders of magnitude larger than the eddy turnover time scale
