Diet and risk for breast cancer recurrence and survival
Dietary factors may influence the risk for breast cancer and also the prognosis following diagnosis and treatment. The aim of this study was to assess whether self-reported prediagnosis diet or other patient factors associated with breast cancer incidence were predictive of recurrence and survival. Patients (n=149) diagnosed with primary breast cancer between 1989 and 1991 were followed for five or more years. Total energy (hazard ratio (HR)=1.58, 95%, confidence interval (CI)= 1.05, 2.38) as well as total (HR = 1.46, 95% CI = 1.05, 2.01), saturated (HR = 1.79,95% CI = 1.05, 3.04), and monounsaturated (HR = 1.65, 95% CI = 1.09,2.49) fat intakes were associated with increased risk, and energy-adjusted bread and cereal consumption (HR = 0.55, 95% CI = 0.33, 0.93) with decreased risk of recurrence. Both total energy (HR = 1.58, 95% CI = 1.03, 2.43) and polyunsaturated fat (HR = 1.84, 95% CI = 1.09, 3.13) intakes were associated with an increased risk of death. All associations between dietary fat and recurrence and survival attenuated following energy adjustment. Oral contraceptive use (HR = 1.28, 95% CI = 1.03, 1.60), lymph node positive status (HR = 2.36, 95% CI = 1.01, 5.49), and tumor stage (HR = 2.22, 95% CI = 1.02, 4.81) were associated with increased risk of recurrence. Tumor stage (HR = 4.96, 95% CI = 1.86, 13.23), lymph node positive status (HR = 3.31, 95% CI = 1.38, 7.95, and estrogen receptor negative status (HR = 2.46, 95% CI = 1.02, 5.94) were associated with increased risk, and arm muscle circumference (HR = 0.27, 95% CI = 0.09, 0.86) and mammographic utilization (HR = 0.77, 95% CI = 0.61, 0.98) with decreased risk of death. Higher levels of energy, fat intakes, and selected patient characteristics (particularly disease stage and anthropometric indicators of adiposity) appear to increase risk of recurrence and/or shortened survival following the diagnosis of breast cancer.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44203/1/10549_2004_Article_194284.pd
The Sloan Digital Sky Survey Quasar Catalog IV. Fifth Data Release
We present the fourth edition of the Sloan Digital Sky Survey (SDSS) Quasar
Catalog. The catalog contains 77,429 objects; this is an increase of over
30,000 entries since the previous edition. The catalog consists of the objects
in the SDSS Fifth Data Release that have luminosities larger than M_i = -22.0
(in a cosmology with H_0 = 70 km/s/Mpc, Omega_M = 0.3, and Omega_Lambda = 0.7)
have at least one emission line with FWHM larger than 1000 km/s, or have
interesting/complex absorption features, are fainter than i=15.0, and have
highly reliable redshifts. The area covered by the catalog is 5740 sq. deg. The
quasar redshifts range from 0.08 to 5.41, with a median value of 1.48; the
catalog includes 891 quasars at redshifts greater than four, of which 36 are at
redshifts greater than five. Approximately half of the catalog quasars have i <
19; nearly all have i < 21. For each object the catalog presents positions
accurate to better than 0.2 arcsec. rms per coordinate, five-band (ugriz)
CCD-based photometry with typical accuracy of 0.03 mag, and information on the
morphology and selection method. The catalog also contains basic radio,
near-infrared, and X-ray emission properties of the quasars, when available,
from other large-area surveys. The calibrated digital spectra cover the
wavelength region 3800--9200A at a spectral resolution of ~2000. The spectra
can be retrieved from the public database using the information provided in the
catalog. The average SDSS colors of quasars as a function of redshift, derived
from the catalog entries, are presented in tabular form. Approximately 96% of
the objects in the catalog were discovered by the SDSS.Comment: 37 pages, Accepted for publication in A
The Sloan Digital Sky Survey Quasar Catalog I. Early Data Release
We present the first edition of the Sloan Digital Sky Survey (SDSS) Quasar
Catalog. The catalog consists of the 3814 objects (3000 discovered by the SDSS)
in the initial SDSS public data release that have at least one emission line
with a full width at half maximum larger than 1000 km/s, luminosities brighter
than M_i^* = -23, and highly reliable redshifts. The area covered by the
catalog is 494 square degrees; the majority of the objects were found in SDSS
commissioning data using a multicolor selection technique. The quasar redshifts
range from 0.15 to 5.03. For each object the catalog presents positions
accurate to better than 0.2" rms per coordinate, five band (ugriz) CCD-based
photometry with typical accuracy of 0.05 mag, radio and X-ray emission
properties, and information on the morphology and selection method. Calibrated
spectra of all objects in the catalog, covering the wavelength region 3800 to
9200 Angstroms at a spectral resolution of 1800-2100, are also available. Since
the quasars were selected during the commissioning period, a time when the
quasar selection algorithm was undergoing frequent revisions, the sample is not
homogeneous and is not intended for statistical analysis.Comment: 27 pages, 4 figures, 4 tables, accepted by A
The Sloan Digital Sky Survey Quasar Catalog V. Seventh Data Release
We present the fifth edition of the Sloan Digital Sky Survey (SDSS) Quasar
Catalog, which is based upon the SDSS Seventh Data Release. The catalog, which
contains 105,783 spectroscopically confirmed quasars, represents the conclusion
of the SDSS-I and SDSS-II quasar survey. The catalog consists of the SDSS
objects that have luminosities larger than M_i = -22.0 (in a cosmology with H_0
= 70 km/s/Mpc Omega_M = 0.3, and Omega_Lambda = 0.7) have at least one emission
line with FWHM larger than 1000 km/s or have interesting/complex absorption
features, are fainter than i > 15.0 and have highly reliable redshifts. The
catalog covers an area of 9380 deg^2. The quasar redshifts range from 0.065 to
5.46, with a median value of 1.49; the catalog includes 1248 quasars at
redshifts greater than four, of which 56 are at redshifts greater than five.
The catalog contains 9210 quasars with i < 18; slightly over half of the
entries have i< 19. For each object the catalog presents positions accurate to
better than 0.1" rms per coordinate, five-band (ugriz) CCD-based photometry
with typical accuracy of 0.03 mag, and information on the morphology and
selection method. The catalog also contains radio, near-infrared, and X-ray
emission properties of the quasars, when available, from other large-area
surveys. The calibrated digital spectra cover the wavelength region 3800-9200
Ang. at a spectral resolution R = 2000 the spectra can be retrieved from the
SDSS public database using the information provided in the catalog. Over 96% of
the objects in the catalog were discovered by the SDSS. We also include a
supplemental list of an additional 207 quasars with SDSS spectra whose archive
photometric information is incomplete.Comment: Accepted, to appear in AJ, 7 figures, electronic version of Table 2

High-Redshift Quasars Found in Sloan Digital Sky Survey Commissioning Data V. Hobby-Eberly Telescope Observations
We report the discovery of 27 quasars with redshifts between 3.58 and 4.49.
The objects were identified as high-redshift candidates based on their colors
in Sloan Digital Sky Survey commissioning data. The redshifts were confirmed
with low resolution spectra obtained at the Hobby-Eberly Telescope. The
quasars' magnitudes range from 18.55 to 20.97. Nearly 60% of the quasar
candidates observed are confirmed spectroscopically as quasars. Two of the
objects are Broad Absorption Line quasars, and several other quasars appear to
have narrow associated absorption features.Comment: 20 pages, 4 figures, AJ accepte
L Dwarfs Found in Sloan Digital Sky Survey Commissioning Data II. Hobby-Eberly Telescope Observations
Low dispersion optical spectra have been obtained with the Hobby-Eberly
Telescope of 22 very red objects found in early imaging data from the Sloan
Digital Sky Survey. The objects are assigned spectral types on the 2MASS system
(Kirkpatrick et al. 1999) and are found to range from late M to late L. The
red- and near-infrared colors from SDSS and 2MASS correlate closely with each
other, and most of the colors are closely related to spectral type in this
range; the exception is the (i^* - z^*) color, which appears to be independent
of spectral type between about M7 and L4. The spectra suggest that this
independence is due to the disappearance of the TiO and VO absorption in the
i-band for later spectral types; to the presence of strong Na I and K I
absorption in the i-band; and to the gradual disappearance of the 8400 Angstrom
absorption of TiO and FeH in the z-band.Comment: 20 pages, 7 figures, accepted by AJ, a version with higher resolution

Early Social Cognition: Alternatives to Implicit Mindreading
According to the BD-model of mindreading, we primarily understand others in terms of beliefs and desires. In this article we review a number of objections against explicit versions of the BD-model, and discuss the prospects of using its implicit counterpart as an explanatory model of early emerging socio-cognitive abilities. Focusing on recent findings on so-called âimplicitâ false belief understanding, we put forward a number of considerations against the adoption of an implicit BD-model. Finally, we explore a different way to make sense of implicit false belief understanding in terms of keeping track of affordances
Pretense and Imagination
Issues of pretense and imagination are of central interest to philosophers, psychologists, and researchers in allied fields. In this entry, we provide a roadmap of some of the central themes around which discussion has been focused. We begin with an overview of pretense, imagination, and the relationship between them. We then shift our attention to the four specific topics where the disciplines' research programs have intersected or where additional interactions could prove mutually beneficial: the psychological underpinnings of performing pretense and of recognizing pretense, the cognitive capacities involved in imaginative engagement with fictions, and the real-world impact of make-believe. In the final section, we discuss more briefly a number of other mental activities that arguably involve imagining, including counterfactual reasoning, delusions, and dreaming
The Sloan Digital Sky Survey Quasar Catalog III. Third Data Release
We present the third edition of the Sloan Digital Sky Survey (SDSS) Quasar
Catalog. The catalog consists of the 46,420 objects in the SDSS Third Data
Release that have luminosities larger than M_i = -22 (in a cosmology with H_0 =
70 km/s/Mpc, Omega_M = 0.3, and Omega_Lambda = 0.7), have at least one emission
line with FWHM larger than 1000 km/s or are unambiguously broad absorption line
quasars, are fainter than i = 15.0, and have highly reliable redshifts. The
area covered by the catalog is 4188 sq. deg. The quasar redshifts range from
0.08 to 5.41, with a median value of 1.47; the high-redshift sample includes
520 quasars at redshifts greater than four, of which 17 are at redshifts
greater than five. For each object the catalog presents positions accurate to
better than 0.2 arcsec. rms per coordinate, five-band (ugriz) CCD-based
photometry with typical accuracy of 0.03 mag, and information on the morphology
and selection method. The catalog also contains radio, near-infrared, and X-ray
emission properties of the quasars, when available, from other large-area
surveys. The calibrated digital spectra cover the wavelength region 3800--9200A
at a spectral resolution about 2000; the spectra can be retrieved from the
public database using the information provided in the catalog. A total of
44,221 objects in the catalog were discovered by the SDSS; 28,400 of the SDSS
discoveries are reported here for the first time.Comment: 41 pages, 7 figures, Accepted for publication in A
