Nick Joaquin’s Cándido’s Apocalypse: Re-imagining the Gothic in a Postcolonial Philippines
In this context, this paper explores the idea of the Gothic in Joaquin’s writing and how it relates to Joaquin being the “most original voice in postcolonial Philippine writing.” In 1972, the University of Queensland Press featured Joaquin’s works in its Asian and Pacific writing series. This “new” collection, Tropical Gothic (1972), contained his significant early works published in Prose and Poems (1952) plus his novellas. This collection’s title highlights a specific aspect of Joaquin’s 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 (Cándido’s Apocalypse) interrogates the neurosis of the nation—a 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.
Turbulent mixing at a stable density interface : the variation of the buoyancy flux–gradient relation
Experiments conducted on mixing across a stable density interface in a turbulent Taylor–Couette 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
Inhomogeneous Gain Saturation in EDF: Experiment and Modeling
Erbium-Doped Fiber Amplifiers can present holes in spectral gain in
Wavelength Division Multiplexing operation. The origin of this inhomogeneous
saturation behavior is still a subject of controversy. In this paper we present
both an experimental methods and a gain's model. Our experimental method allow
us to measure the first homogeneous linewidth of the 1.5 m erbium emission
with gain spectral hole burning consistently with the other measurement in the
literature and the model explains the differences observed in literature
between GSHB and other measurement methods
Eigenelements of a General Aggregation-Fragmentation Model
We consider a linear integro-differential equation which arises to describe
both aggregation-fragmentation processes and cell division. We prove the
existence of a solution (\lb,\U,\phi) to the related eigenproblem. Such
eigenelements are useful to study the long time asymptotic behaviour of
solutions as well as the steady states when the equation is coupled with an
ODE. Our study concerns a non-constant transport term that can vanish at
since it seems to be relevant to describe some biological processes like
proteins aggregation. Non lower-bounded transport terms bring difficulties to
find estimates. All the work of this paper is to solve this problem
using weighted-norms
Efficient white noise sampling and coupling for multilevel Monte Carlo with non-nested meshes
When solving stochastic partial differential equations (SPDEs) driven by
additive spatial white noise, the efficient sampling of white noise
realizations can be challenging. Here, we present a new sampling technique that
can be used to efficiently compute white noise samples in a finite element
method and multilevel Monte Carlo (MLMC) setting. The key idea is to exploit
the finite element matrix assembly procedure and factorize each local mass
matrix independently, hence avoiding the factorization of a large matrix.
Moreover, in a MLMC framework, the white noise samples must be coupled between
subsequent levels. We show how our technique can be used to enforce this
coupling even in the case of non-nested mesh hierarchies. We demonstrate the
efficacy of our method with numerical experiments. We observe optimal
convergence rates for the finite element solution of the elliptic SPDEs of
interest in 2D and 3D and we show convergence of the sampled field covariances.
In a MLMC setting, a good coupling is enforced and the telescoping sum is
respected.Comment: 28 pages, 10 figure
Household Demand for Employer-Based Health Insurance
We use the 1996 Medical Expenditure Panel Survey to estimate a model of household demand for employer-based health insurance, explicitly investigating differences in behavior between households with two potential sources of coverage and those with one source. Own and cross-price elasticities are estimated for three types of health plans, including exclusive provider organizations, any provider organizations, and mixed provider organizations. We find that the premium, family size, income, and wealth significantly affect demand. Our elasticity estimates reveal an overall, small behavioral response to changes in price with respect to health plan switching and take-up. Finally, we discuss the implications of our findings with respect to employer benefit design.
