Grierson's ghost never dies: The Fiji Film Unit 1970-1985
This article exlpores what happens when a documentary film form developed within a specific social, ideological, institutoinal, and aesthetic context—namely, the so-called British Documentary Movement, under the aegis of John Grierson—is deployed in several layers of argument involved, but I will pursue only one of them in the space available here. At a kind of metatheoretical level, it is arguable that Indigenous and Asian cultures are inimical to core values of the Western documentary project: in particular, to the belief in, and rhetorical power of, the material, historical word. In these societies, what might be called 'spiritual' or 'other' worlds have as much everyday reality as Griersonian 'actuality'.

Plugging the attention deficit: perceptual load counters increased distraction in ADHD
Objective: Increased vulnerability to extraneous distraction is a key symptom of Attention-Deficit Hyperactivity Disorder (ADHD), which may have particularly disruptive consequences. Here we apply Load Theory of attention to increase understanding of this symptom, and to explore a potential method for ameliorating it. Previous research in nonclinical populations has highlighted increased perceptual load as a means of improving the ability to focus attention and avoid distraction. The present study examines whether adults with ADHD can also benefit from conditions of high perceptual load to improve their focused attention abilities. Method: We tested adults with ADHD and age- and IQ-matched controls on a novel measure of irrelevant distraction under load, designed to parallel the form of distraction that is symptomatic of ADHD. During a letter search task, in which perceptual load was varied through search set size, participants were required to ignore salient yet entirely irrelevant distractors (colorful images of cartoon characters) presented infrequently (10% of trials). Results: The presence of these distractors produced a significantly greater interference effect on the search RTs for the adults with ADHD compared with controls, p = .005, ηp² = .231. Perceptual load, however, significantly reduced distractor interference for the ADHD group and was as effective in reducing the elevated distractor interference in ADHD as it was for controls. Conclusions: These findings clarify the nature of the attention deficit underlying increased distraction in ADHD, and demonstrate a tangible method for overcoming it.

Determining the Properties and Evolution of Red Galaxies from the Quasar Luminosity Function
(Abridged) We study the link between quasars and the red galaxy population
using a model for the self-regulated growth of supermassive black holes in
mergers involving gas-rich galaxies. Using a model for quasar lifetimes and
evolution motivated by hydrodynamical simulations of galaxy mergers, we
de-convolve the observed quasar luminosity function at various redshifts to
determine the rate of formation of black holes of a given final mass.
Identifying quasar activity with the formation of spheroids in the framework of
the merger hypothesis, this enables us to deduce the corresponding rate of
formation of spheroids with given properties as a function of redshift. This
allows us to predict, for the red galaxy population, the distribution of galaxy
velocity dispersions, the mass function, mass density, star formation rates,
the luminosity function in many observed wavebands (NUV, U, B, V, R, I, J, H,
K), the total red galaxy number density and luminosity density, the
distribution of colors as a function of magnitude and velocity dispersion for
several different wavebands, the distribution of mass to light ratios vs. mass,
the luminosity-size relations, and the typical ages and distribution of ages
(formation redshifts) as a function of both mass and luminosity. For each of
these quantities, we predict the evolution from redshift z=0-6. Each of our
predictions agrees well with existing observations, without the addition of
tunable parameters; the essential observational inputs come from the observed
quasar luminosity function. These predictions are skewed by several orders of
magnitude if we adopt simpler, traditional models of quasar lifetimes in which
quasars turn on/off or follow simple exponential light curves, instead of the
more complicated evolution implied by our simulations.Comment: 28 pages, 22 figures, matches version accepted to Ap
