The Grenadian Crisis and the Caribbean Left
SUMMARY Prior to October 1983 âpopular forcesâ had established a hitherto unmatched degree of hegemony throughout the Caribbean region. The self?destruction of the Grenadian revolution opened the way to the restoration of colonial or neo colonial principles under US hegemony. The article examines the importance of democracy in the Caribbean political tradition, and the responsibility of the New Jewel Movement's leadership, and of the Caribbean intelligentsia who supported them, for ignoring this. RESUMEN La crisis de Grenada y la izquierda caribeña Con anterioridad a octubre de 1983, las âfuerzas popularesâ establecieron un grado de hegemonĂa hasta entonces inĂ©dito en la regiĂłn caribeña. La autodestrucciĂłn de la revoluciĂłn de Grenada abriĂł el camino para la restauraciĂłn de los principios coloniales o neocoloniales bajo la hegemonĂa estadounidense. El artĂculo examina la importancia de la democracia en la tradiciĂłn polĂtica del Caribe y la responsabilidad que le cabe a la lideranza del Movimiento New Jewel, asĂ como a la intelectualidad caribeña que la apoyĂł, por haberlo ignorado. SOMMAIRE La crise de la Grenade et la gauche Antillaise Avant Octobre 1983, les âforces populairesâ ont Ă©tabli une hĂ©gĂ©monie Ă un degrĂ© jusqu Ă present inĂ©galĂ© dans la rĂ©gion des Antilles.

L'article examine l'importance de la DĂ©mocratie dans la tradition politique des CaraĂŻbes et la responsabilitĂ© de la direction du mouvement du âNouveau Bijouâ et de l'Intelligentsia des CaraĂŻbes qui la supporte et veut ignorer cette premiĂšre donnĂ©e
Lift at low Reynolds number
Lift forces are widespread in hydrodynamics. These are typically observed for
big and fast objects, and are often associated with a combination of fluid
inertia (i.e. large Reynolds numbers) and some specific symmetry-breaking
mechanism. In contrast, low-Reynolds-number flows are usually overdamped and do
not exhibit such peculiar and interesting features. However, the inclusion of
boundary effects qualitatively changes this picture. Indeed, in the context of
soft and biological matter, recent studies have revealed the emergence of novel
lift forces generated by boundary softness, flow gradients and/or surface
charges. The aim of the present review is to gather and analyse this corpus of
literature, in order to identify and unify the questioning within the
associated communities, and pave the way towards future research around lift
effects at low Reynolds numbers
The stellar kinematics and populations of boxy bulges: cylindrical rotation and vertical gradients
Boxy and peanut-shaped bulges are seen in about half of edge-on disc
galaxies. Comparisons of the photometry and major-axis gas and stellar
kinematics of these bulges to simulations of bar formation and evolution
indicate that they are bars viewed in projection. If the properties of boxy
bulges can be entirely explained by assuming they are bars, then this may imply
that their hosts are pure disc galaxies with no classical bulge. A handful of
these bulges, including that of the Milky Way, have been observed to rotate
cylindrically, i.e. with a mean stellar velocity independent of height above
the disc. In order to assess whether such behaviour is ubiquitous in boxy
bulges, and whether a pure disc interpretation is consistent with their stellar
populations, we have analysed the stellar kinematics and populations of the
boxy or peanut-shaped bulges in a sample of five edge-on galaxies. We placed
slits along the major axis of each galaxy and at three offset but parallel
positions to build up spatial coverage. The boxy bulge of NGC3390 rotates
perfectly cylindrically within the spatial extent and uncertainties of the
data. This is consistent with the metallicity and alpha-element enhancement of
the bulge, which are the same as in the disk. This galaxy is thus a pure disc
galaxy. The boxy bulge of ESO311-G012 also rotates very close to cylindrically.
The boxy bulge of NGC1381 is neither clearly cylindrically nor
non-cylindrically rotating, but it has a negative vertical metallicity gradient
and is alpha-enhanced with respect to its disc, suggesting a composite bulge
comprised of a classical bulge and bar (and possibly a discy pseudobulge)
[abridged] Even this relatively small sample is sufficient to demonstrate that
boxy bulges display a range of rotational and population properties, indicating
that they do not form a homogeneous class of object.Comment: MNRAS accepted. 10 page
Homeostatic Eosinophils: Characteristics and Functions
Eosinophils are typically considered to be specialized effector cells that are recruited to the tissues as a result of T helper type 2 (Th2) cell responses associated with helminth infections or allergic diseases such as asthma. Once at the site of injury, eosinophils release their cytotoxic granule proteins as well as preformed cytokines and lipid mediators, contributing to parasite destruction but also to exacerbation of inflammation and tissue damage. Accumulating evidence indicates that, besides their roles in Th2 responses, eosinophils also regulate homeostatic processes at steady state, thereby challenging the exclusive paradigm of the eosinophil as a destructive and inflammatory cell. Indeed, under baseline conditions, eosinophils rapidly leave the bloodstream to enter tissues, mainly the gastrointestinal tract, lungs, adipose tissue, thymus, uterus, and mammary glands, where they regulate a variety of important biological functions, such as immunoregulation, control of glucose homeostasis, protection against obesity, regulation of mammary gland development, and preparation of the uterus for pregnancy. This article provides an overview of the characteristics and functions of these homeostatic eosinophils
Efficient Processing of Spatial Joins Using R-Trees
Abstract: In this paper, we show that spatial joins are very suitable to be processed on a parallel hardware platform. The parallel system is equipped with a so-called shared virtual memory which is well-suited for the design and implementation of parallel spatial join algorithms. We start with an algorithm that consists of three phases: task creation, task assignment and parallel task execu-tion. In order to reduce CPU- and I/O-cost, the three phases are processed in a fashion that pre-serves spatial locality. Dynamic load balancing is achieved by splitting tasks into smaller ones and reassigning some of the smaller tasks to idle processors. In an experimental performance compar-ison, we identify the advantages and disadvantages of several variants of our algorithm. The most efficient one shows an almost optimal speed-up under the assumption that the number of disks is sufficiently large. Topics: spatial database systems, parallel database systems
National trends in Aboriginal and Torres Strait Islander smoking and quitting, 1994-2008
Objective: To describe the trends in the prevalence of smoking, quitting and initiation among Aboriginal and Torres Strait Islander men and women aged 18 years and over. Methods: Analysis of responses to smoking questions in national Indigenous surveys in 1994, 2002, 2004 and 2008. Results: Male Indigenous smoking prevalence fell significantly from 58.5% in 1994 to 52.6% in 2008, an absolute decrease of 0.4 (CI 0.1-0.7)% per year, with the same decline in remote and non- remote areas. Female smoking fell from 51.0% to 47.4%, with markedly different changes in remote and non-remote areas. In non-remote areas, there was an absolute decrease in female smoking of 0.5 (CI 0.2-0.9)% per year, but in remote areas, female smoking increased by 0.4 (CI 0.0-0.8)% per year. From 2002 to 2008, the percentage of ever-smokers who had quit (quit ratio) increased absolutely by 1% per year in both men and women, remote and non-remote areas. Results about trends in initiation were inconclusive. Conclusions and Implications: Health Minister Roxon has committed to halving the Indigenous smoking prevalence by 2018, and has dramatically increased Indigenous-specific funding and activity in tobacco control. The reported historical trends in this paper are encouraging as they occurred at a time when there was little such tobacco control activity focused on Aboriginal and Torres Strait Islander people. However, to meet the Ministerâs goal, Indigenous smoking prevalence will need to fall more than six times as quickly as occurred from 1994 to 2008
