What is the attraction of nurse training as a model for professional education? An analysis of field and habitus in the construction of curricula for nurse, teacher and police officer training.
‘Nurse training’ looks like the new ‘gold standard’ for educating public service professionals. The Education Secretary, Michael Gove, cites it for the restructuring of teacher training in the Education Bill now before Parliament; and the Home Office commissioned Neyroud Report (2011) is similarly motivated in recommending a new police training approach. With consultation on the latter now underway, legislation is expected in the next Parliament. This paper questions the rush to uniformity in professional education. ‘Uniformity’ assumes quality control through ownership of the relevant competences by an agency which then validates a syllabus for delivery by approved HE/ profession partners. The partnership implies a value-free, technical delivery-vehicle, independent of the historical and cultural forces structuring professional fields.
Our research was based on a pilot study of interviews with nurse, teacher and police educators. The aim was to understand the part lecturers play in the construction of professional curricula. We use the concept of ‘field’ to model the interplay of academy and profession influences; and the concept of ‘habitus’ to understand lecturers’ participation within it. We suggest HE partnerships are characterised by field structures constituted by idiosyncratic professional demands for education and training, and the specific historical and cultural influences of the contributing institutions. Professional curricula are the product of lecturers positioning themselves within those institutional fields.
There is little precision in any formulation for training, i.e. its ability to produce intended outcomes. It is not the form per se which produces the practitioner, thus policy makers cannot anticipate how a nursing approach will work for teaching or policing. The curriculum is produced by complex and unpredictable interactions between habitus and field; tinkering with it may have unexpected consequences – and this includes the loss of what we already think is good
A ‘new police studies’ for a ‘new professional police service’: changes and challenges from a UK perspective.
The FIRST-2MASS Red Quasar Survey
Combining radio observations with optical and infrared color selection --
demonstrated in our pilot study to be an efficient selection algorithm for
finding red quasars -- we have obtained optical and infrared spectroscopy for
120 objects in a complete sample of 156 candidates from a sky area of 2716
square degrees. Consistent with our initial results, we find our selection
criteria -- J-K>1.7, R-K>4.0 -- yield a ~50% success rate for discovering
quasars substantially redder than those found in optical surveys. Comparison
with UVX- and optical color-selected samples shows that >~ 10% of the quasars
are missed in a magnitude-limited survey. Simultaneous two-frequency radio
observations for part of the sample indicate that a synchrotron continuum
component is ruled out as a significant contributor to reddening the quasars'
spectra. We go on to estimate extinctions for our objects assuming their red
colors are caused by dust. Continuum fits and Balmer decrements suggest E(B-V)
values ranging from near zero to 2.5 magnitudes. Correcting the K-band
magnitudes for these extinctions, we find that for K <= 14.0, red quasars make
up between 25% and 60% of the underlying quasar population; owing to the
incompleteness of the 2MASS survey at fainter K-band magnitudes, we can only
set a lower limit to the radio-detected red quasar population of >20-30%.Comment: 80 pages (single-column, preprint format) 20 figures, Accepted for

Foreground Predictions for the Cosmic Microwave Background Power Spectrum from Measurements of Faint Inverted Radio Sources at 5 GHz
We present measurements of a population of matched radio sources at 1.4 and 5
GHz down to a flux limit of 1.5 mJy in 7 sq. degs. of the NOAO Deep Field
South. We find a significant fraction of sources with inverted spectral indices
that all have 1.4 GHz fluxes less than 10 mJy, and are therefore too faint to
have been detected and included in previous radio source count models that are
matched at multiple frequencies. Combined with the matched source population at
1.4 and 5 GHz in 1 sq. deg. in the ATESP survey, we update models for the 5 GHz
differential number counts and distributions of spectral indices in 5 GHz flux
bins that can be used to estimate the unresolved point source contribution to
the cosmic microwave background temperature anisotropies. We find a shallower
logarithmic slope in the 5 GHz differential counts than in previously published
models for fluxes < 100 mJy as well as larger fractions of inverted spectral
indices at these fluxes. Because the Planck flux limit for resolved sources is
larger than 100 mJy in all channels, our modified number counts yield at most a
10% change in the predicted Poisson contribution to the Planck temperature
power spectrum. For a flux cut of 5 mJy with the South Pole Telescope and a
flux cut of 20 mJy with the Atacama Cosmology Telescope we predict a ~30% and
~10% increase, respectively, in the radio source Poisson power in the lowest
frequency channels of each experiment relative to that predicted by previous
models.Comment: 14 pages, 9 figures, includes ApJ proof correction
The Gravitational Lens Candidate FBQ 1633+3134
We present our ground-based optical imaging, spectral analysis, and high
resolution radio mapping of the gravitational lens candidate FBQ 1633+3134.
This z=1.52, B=17.7 quasar appears double on CCD images with an image
separation of 0.66 arcseconds and a flux ratio of ~3:1 across BVRI filters. A
single 0.27 mJy radio source is detected at 8.46 GHz, coincident to within an
arcsecond of both optical components, but no companion at radio wavelengths is
detected down to a flux level of 0.1 mJy (3 sigma). Spectral observations
reveal a rich metal-line absorption system consisting of a strong Mg II doublet
and associated Fe I and Fe II absorption features, all at an intervening
redshift of z=0.684, suggestive of a lensing galaxy. Point spread function
subtraction however shows no obvious signs of a third object between the two
quasar images, and places a detection limit of I > 23.0 if such an object
exists. Although the possibility that FBQ 1633+3134 is a binary quasar cannot
be ruled out, the evidence is consistent with it being a single quasar lensed
by a faint, metal-rich galaxy.Comment: 24 pages, 5 figures. Accepted by AJ. A calibration error affecting B
and V band apparent magnitudes has been corrected. The conclusions of the
paper are not change
An FeLoBAL Binary Quasar
In an ongoing infrared imaging survey of quasars at Keck Observatory, we have
discovered that the z=1.285 quasar SDSS J233646.2-010732.6 comprises two point
sources with a separation of 1.67". Resolved spectra show that one component is
a standard quasar with a blue continuum and broad emission lines; the other is
a broad absorption line (BAL) quasar, specifically, a BAL QSO with prominent
absorption from MgII and metastable FeII, making it a member of the ``FeLoBAL''
class. The number of known FeLoBALs has recently grown dramatically from a
single example to more than a dozen, including a gravitationally lensed example
and the binary member presented here, suggesting that this formerly rare object
may be fairly common. Additionally, the presence of this BAL quasar in a
relatively small separation binary adds to the growing evidence that the BAL
phenomenon is not due to viewing a normal quasar at a specific orientation, but
rather that it is an evolutionary phase in the life of many, if not all,
quasars, and is particularly associated with conditions found in interacting
systems.Comment: AASTEX 13 pp., 4 figs; accepted by ApJ Letter
Tradeoff analysis for electric power planning in New England
The use of a multi-attribute trade-off analysis technique as a vehicle to provide information to a diverse group of electric industry interests can play a beneficial role for developing long-range strategies for the electric power sector. The advisory group/analysis team structure presented here allows different groups to evaluate multiple issues simultaneously, incorporating the range of supply and demand options, and future uncertainties characteristic of complex systems.The initial phase of such an Integrated Resource Planning project for New England electric power industry has identified that: significant gains in the areas of reliability and environmental emissions can be made by the introduction of new generating technologies; the recent emphasis on natural gas fired technologies should be matched by an effort to ensure adequate supplies of gas, and other effort to guard against fuel related vulnerabilities
