The Pre-K Pinch: Early Education and the Middle Class
Reviews evidence on the benefits of pre-K programs and the difficulties families that do not qualify for state programs face in paying for early education. Calls for high-quality, voluntary, state-funded programs for all. Includes state-level analyses
Leadership Matters: Governors' Pre-K Proposals, Fiscal Year 2009
Through an annual review of governors' budget proposals and state of the state addresses, rates governors' commitments to early education, from "heroes" to "all talk and no action." Summarizes all state and District of Columbia pre-K budget changes
Respiratory Virus in Cystic Fibrosis — A Review of the Literature
Life expectancy in Cystic Fibrosis (CF) has improved dramatically in the last few decades; this is very much due to the emergence of disease-modifying treatments, optimisation of nutritional status and the inception of specialist CF units. However, progressive obstructive lung disease characterised by chronic inflammation, bacterial colonisation and recurrent infections of the lung, resulting in irreversible pulmonary damage, remains the major cause of mortality in individuals with CF. Historically, bacterial infections are the major pathogens accounting for clinical deterioration in CF. More recently, there has been emerging evidence to support respiratory viruses being accountable for the colonisation of bacteria and progression of lung disease in CF. This chapter sought to provide an overview on the impact of respiratory viruses in CF lung disease, the interaction between viruses and bacteria, the preventative and therapeutic measures that are currently available for the management of viral lung disease in CF
Chandra Observation of the Cluster Environment of a WAT Radio Source in Abell 1446
Wide-angle tail (WAT) radio sources are often found in the centers of galaxy
clusters where intracluster medium (ICM) ram pressure may bend the lobes into
their characteristic C-shape. We examine the low redshift (z=0.1035) cluster
Abell 1446, host to the WAT radio source 1159+583. The cluster exhibits
possible evidence for a small-scale cluster-subcluster merger as a cause of the
WAT radio source morphology. This evidence includes the presence of temperature
and pressure substructure along the line that bisects the WAT as well as a
possible wake of stripped interstellar material or a disrupted cool core to the
southeast of the host galaxy. A filament to the north may represent cool,
infalling gas that's contributing to the WAT bending while spectroscopically
determined redshifts of member galaxies may indicate some component of a merger
occurring along the line-of-sight. The WAT model of high flow velocity and low
lobe density is examined as another scenario for the bending of 1159+583. It
has been argued that such a model would allow the ram pressure due to the
galaxy's slow motion through the ICM to shape the WAT source. A temperature
profile shows that the cluster is isothermal (kT= 4.0 keV) in a series of
annuli reaching a radius of 400 kpc. There is no evidence of an ongoing cooling
flow. Temperature, abundance, pressure, density, and mass profiles, as well as
two-dimensional maps of temperature and pressure are presented.Comment: 40 AASTeX pages including 15 postscript figures; accepted for

華人基督教界對霍金宇宙學的評論
自史蒂芬·霍金(Stephen Hawking) 的暢銷科普著作《時間簡史》(以下簡稱《簡史》) 在上世紀八十年代末問世以來,至今天二十一世紀,華人基督教界就他宇宙無起點的論述仍有相當之評論,但可惜對評論未有綜合分析。評論者因寫作目的,也甚少交代霍金宇宙學的來龍去脈。故本文嘗試略述霍金宇宙學的歷史背景及發展經過,繼而舉出華人基督教界的評論,帶出其獨特性,並提出商確的地方,以反省未來可行路向
When Does F*** Not Mean F***?: FCC v. Fox Television Stations and a Call for Protecting Emotive Speech
The Supreme Court of the United States does not always deal cogently with nontraditional language. The most recent example is FCC v. Fox Television Stations, in which the Justices became sidetracked into attempting to define the f-word and then to determine whether, when used as a fleeting expletive rather than repeatedly, the word is indecent for broadcast purposes. The Court would do well to avoid definitions and heed Justice John Marshall Harlan\u27s advice in Cohen v. California to provide protection for the emotive, as well as the cognitive, element of speec

Cluster Winds Blow along Supercluster Axes
Within Abell galaxy clusters containing wide-angle tailed radio sources,
there is evidence of a ``prevailing wind'' which directs the WAT jets. We study
the alignment of WAT jets and nearby clusters to test the idea that this wind
may be a fossil of drainage along large-scale supercluster axes. We also test
this idea with a study of the alignment of WAT jets and supercluster axes.
Statistical test neighbours indicate no alignment of WAT jets towards nearest
clusters, but do indicate approximately 98% confidence in alignment with the
long axis of the supercluster in which the cluster lies. We find a preferred
scale for such superclusters of order 25 Mpc .Comment: Latex, 5 pages, with 5 postscript figures. To be published in MNRAS.
