Photometric redshifts and selection of high redshift galaxies in the NTT and Hubble Deep Fields

We present and compare in this paper new photometric redshift catalogs of the galaxies in three public fields: the NTT Deep Field, the HDF-N and the HDF-S. Photometric redshifts have been obtained for thewhole sample, by adopting a $\chi^2$ minimization technique on a spectral library drawn from the Bruzual and Charlot synthesis models, with the addition of dust and intergalactic absorption. The accuracy, determined from 125 galaxies with known spectroscopic redshifts, is $\sigma_z\sim 0.08 (0.3)$ in the redshift intervals $z=0-1.5 (1.5-3.5)$. The global redshift distribution of I-selected galaxies shows a distinct peak at intermediate redshifts, z~0.6 at I_{AB}<26 and z~0.8 at I_{AB}<27.5 followed by a tail extending to z~6. We also present for the first time the redshift distribution of the total IR-selected sample to faint limits ($Ks \leq 21$ and $J\leq22$). It is found that the number density of galaxies at 1.25<z<1.5 is ~ 0.1 /arcmin^22 at J<=21 and ~1./arcmin^2} at J<22, and drops to 0.3/arcmin^2 (at J<22) at 1.5<z<2. The HDFs data sets are used to compare the different results from color selection criteria and photometric redshifts in detecting galaxies in the redshift range 3.5<z<4.5 Photometric redshifts predict a number of high z candidates in both the HDF-N and HDF-S that is nearly 2 times larger than color selection criteria, and it is shown that this is primarily due to the inclusion of dusty models that were discarded in the original color selection criteria by Madau et al 1998. In several cases, the selection of these objects is made possible by the constraints from the IR bands. Finally, it is shown that galactic M stars may mimic z>5 candidates in the HDF filter set and that the 4 brightest candidates at $z>5$ in the HDF-S are indeed most likely M stars.

DD-optimal saturated designs: a simulation study

In this work we focus on saturated $D$-optimal designs. Using recent results, we identify $D$-optimal designs with the solutions of an optimization problem with linear constraints. We introduce new objective functions based on the geometric structure of the design and we compare them with the classical $D$-efficiency criterion. We perform a simulation study. In all the test cases we observe that designs with high values of $D$-efficiency have also high values of the new objective functions.Comment: 8 pages.

The effects of social problem-solving training in an inclusive kindergarten classroom

The purpose of this study was for students with disabilities in an inclusive setting to improve socially from social problem solving training. An eight-week social problem-solving training program (SPS) was administered to twenty-three children. Three participants took part in this study. One child was classified as being emotionally disturbed and two other children were classified with attention deficit hyperactivity disorder (ADHD). The behaviors observed were: positive social interaction, the ability to make friends, and attending behavior during big group, small group, and playtime. The teacher and teacher assistant observed the three participants using a baseline analysis. Results did exhibit a slight increase in positive behavior in all three areas observed resulting from the social problem solving training program. However, future studies should be conducted over a longer period of time involving more participants to see the program\u27s true effectiveness

Cotton fiber testing by shippers in Memphis, Tennessee

This study is concerned with the present and the probable future effects of cotton fiber testing on the buying, assembling, and selling of cotton by shippers in the Memphis market. The problem may be sub-divided into the following seven objectives: 1. To determine the extent and use of cotton fiber tests in the Memphis market. 2. To determine the reasons for using cotton fiber tests. 3. To determine what operating practices are used in testingCotton. 4. To determine how fiber tests are used in buying and selling cotton. 5. To determine the cost of fiber testing. 6. To determine the shippers\u27 appraisal of cotton fiber tests in marketing cotton. 7. To compare the use of fiber tests in the Memphis market with their use in other areas of the country
