Higher education academic salaries in the UK
It is widely believed that higher education academic salaries are too low, and that this may lead to a ‘brain drain’ and also lower quality in higher education, as universities fail to attract the ‘brightest and the best’. We compare the salaries of Higher Education teaching professionals in the UK with those of other comparable professionals. We compare academic salaries to a range of occupational groupings that one might view as similar, in terms of unobserved characteristics, to academics. We conclude that HE teaching professionals earn lower earnings than most public sector graduates and do particularly poorly compared to most other comparable professionals. In particular, academic earnings compare poorly to those in the legal professions, consultant physicians and dental practitioners (across both the public and private sectors). On the other hand, some public sector workers do worse than HE academics, e.g. FE teachers
Investigation of Atmospheric Reentry for the Space Maneuver Vehicle
This study investigated the atmospheric reentry of the Space Maneuver Vehicle from low-earth orbit using an entry guidance concept similar to the Space Shuttle. The Space Maneuver Vehicle was modeled as a point mass with aerodynamic properties as determined using Newtonian impact theory. For the rarefied-flow transition regime bridging formulae are used to capture the effects of both hypersonic continuum flow and free molecular flow. Constraints to the reentry are developed and a reentry corridor is defined in the drag-velocity plane. Bank angle modulation is established as the primary means for controlling drag and range. The guidance concept is applied to both a high inclination orbit and a low inclination orbit with cross-range requirement. Monte Carlo error analysis validates the ability of the control algorithm to guide reentry in the presence of initial state errors, as well as atmospheric variations
How to have a successful educational meeting on a public issue
"Revised 1/83/2M""Citizens have the duty and opportunity to help make many group decisions about complex issues. Group decisions are those in which two or more people have a voice or vote. The decision may affect one or more persons individually or as a group. The group decision may be of a local nature such as a change in school tax, or a state problem such as water legislation, or a national issue such as commodity referendum. Increasingly there are issues that relate to broad national programs such as energy, international trade or other complex subjects about which there must be broad public support before much can be accomplished by legislation."--First page.So
Hyperon photoproduction in the nucleon resonance region
High-statistics cross sections and recoil polarizations for the reactions γ+p→K++Λ and γ+p→K++Σ0 have been measured at CLAS for center-of-mass energies between 1.6 and 2.3GeV. In the K+Λ channel we confirm a resonance-like structure near W=1.9GeV at backward kaon angles. Our data show more complex s- and u- channel behavior than previously seen, since structure is also present at forward angles, but not at central angles. The position and width change with angle, indicating that more than one resonance is playing a role. Large positive Λ polarization at backward angles, which is also energy dependent, is consistent with sizable s- or u-channel contributions. Presently available model calculations cannot explain these aspects of the data
Spitzer observations of extragalactic H II regions - III. NGC 6822 and the hot star, H II region connection
Using the short-high module of the Infrared Spectrograph on the Spitzer Space
Telescope, we have measured the [S IV] 10.51, [Ne II] 12.81, [Ne III] 15.56,
and [S III] 18.71-micron emission lines in nine H II regions in the dwarf
irregular galaxy NGC 6822. These lines arise from the dominant ionization
states of the elements neon (Ne, Ne) and sulphur (S,
S), thereby allowing an analysis of the neon to sulphur abundance ratio
as well as the ionic abundance ratios Ne/Ne and S/S.
By extending our studies of H II regions in M83 and M33 to the lower
metallicity NGC 6822, we increase the reliability of the estimated Ne/S ratio.
We find that the Ne/S ratio appears to be fairly universal, with not much
variation about the ratio found for NGC 6822: the median (average) Ne/S ratio
equals 11.6 (12.20.8). This value is in contrast to Asplund et al.'s
currently best estimated value for the Sun: Ne/S = 6.5. In addition, we
continue to test the predicted ionizing spectral energy distributions (SEDs)
from various stellar atmosphere models by comparing model nebulae computed with
these SEDs as inputs to our observational data, changing just the stellar
atmosphere model abundances. Here we employ a new grid of SEDs computed with
different metallicities: Solar, 0.4 Solar, and 0.1 Solar. As expected, these
changes to the SED show similar trends to those seen upon changing just the
nebular gas metallicities in our plasma simulations: lower metallicity results
in higher ionization. This trend agrees with the observations.Comment: 22 pages, 13 figures. To be published in MNRAS. reference added and
