Got Women? Hiring and Retaining Female Information Technology Professionals Through Effective Human Resource Marketing

The current pipeline for information technology (IT) professionals is dismal, with increasing jobs and decreasing applicants. We propose that one solution to this problem is encouraging women to pursue careers in IT. Today, women are underrepresented, and as a result, they comprise an untapped market segment. After discussing the current state of the industry, we propose that HR professionals should take a proactive, marketing approach to the recruitment and retention of women in the IT field. Lastly, we provide specific recommendations and discuss approaches taken by several companies to address this dilemma

Gauging Support for Innovative Farmland Preservation Techniques

This paper describes four innovative farmland preservation techniques and gauges support through interviews of key stakeholders: program administrators, lawmakers, and landowners. Four techniques were selected for assessment from approximately 30 novel techniques: rights of first refusal; term conservation easements; land preservation tontines; and agricultural conservation pension. Rights of first refusal was the most favored, although respondents thought effective implementation would need targeting of land and a dedicated funding source. Agricultural conservation pension was also viewed favorably, although considered administratively difficult to implement. Tontines were perceived to be an interesting concept, but confusing, difficult to implement, and ill-defined. Term easements were viewed unfavorably because they did not preserve land permanently.Land Economics/Use,

Trends and Disparities in TB among U.S.-born Black and White Chicago Residents, 1998-2008

ABSTRACT OBJECTIVE: To describe the decline of tuberculosis (TB) cases among U.S.-born non-Hispanic (NH) black and white Chicago residents. METHODS: Data from the National TB Surveillance System was used to analyze trends and characteristics of reported TB cases among U.S.-born NH black and U.S.-born NH white Chicago residents from 1998-2008. RESULTS: Chicago reported a total of 3,821 TB cases over the 11-year time period. Of these, 1,916 were U.S.-born NH black and 235 were U.S.-born NH white. The proportion of cases attributable to U.S.-born NH blacks was 63% (294/469) in 1998 and 34% in 2008 (72/213). Analysis for trends from 2000-2008 revealed a greater than predicted decrease in rates among U.S.-born NH blacks (p CONCLUSION: Despite more TB risk factors in Chicago’s U.S.-born black population, there was a narrowing of TB case disparity in Chicago from 1998-2008. Continued focused strategies aimed at controlling TB are needed

The Tolman Surface Brightness Test for the Reality of the Expansion. III. HST Profile and Surface Brightness Data for Early-Type Galaxies in Three High-Redshift Clusters

Photometric data for 34 early-type galaxies in the three high-redshift clusters Cl 1324+3011 (z = 0.76), Cl 1604+4304 (z = 0.90), and Cl 1604+4321 (z = 0.92), observed with the Hubble Space Telescope (HST) and with the Keck 10-meter telescopes by Oke, Postman & Lubin, are analyzed to obtain the photometric parameters of mean surface brightness, magnitudes for the growth curves, and angular radii at various Petrosian eta radii. The angular radii at eta = 1.3 mag for the program galaxies are all larger than 0.24". All of the galaxies are well resolved at this angular size using HST whose point-spread function is 0.05", half width at half maximum. The data for each of the program galaxies are listed at eta = 1.0, 1.3, 1.5, 1.7, and 2.0 mag. They are corrected by color equations and K terms for the effects of redshift to the rest-frame Cape/Cousins I for Cl 1324+3011 and Cl 1604+4304 and R for Cl 1604+4321. The K corrections are calculated from synthetic spectral energy distributions derived from evolving stellar population models of Bruzual & Charlot which have been fitted to the observed broad-band (BVRI) AB magnitudes of each program galaxy. The listed photometric data are independent of all cosmological parameters. They are the source data for the Tolman surface brightness test made in Paper IV.Comment: 17 pages, 7 figures; accepted for publication in the Astronomical Journa

The Tolman Surface Brightness Test for the Reality of the Expansion. II. The Effect of the Point-Spread Function and Galaxy Ellipticity on the Derived Photometric Parameters

To complete the Tolman surface brightness test on the reality of the expansion of the Universe, we need to measure accurately the surface brightness profiles of the high-redshift galaxy sample. We, therefore, investigate the effects of various sizes of point-spread-functions composed of telescope diffraction, CCD pixel resolutions, and ground-based seeing on the measurements of mean surface brightness. We have done the calculations using two synthetic galaxies of effective radii of 0.70" and 0.25" with point-spread functions of 0.1, 0.3, and 0.9 arcseconds. We have also compared actual observations of three high-redshift galaxies in the cluster Cl 1324 + 3011 (z = 0.76) made both with the Keck telescopes in seeing of about 0.9" and with HST which has a PSF that is approximately ten times smaller. The conclusion is that HST data can be used as far into the galaxy image as a Petrosian metric radius of eta = 1.3 magnitudes, whereas the ground-based data will have systematic errors of up to 2.9 magnitudes in the mean surface brightness at eta values of less than 2.2 magnitudes. In the final section, we compare the differences in derived average surface brightness for nearly circular galaxy images compared with highly flattened images. The comparison is made by using the two reduction procedures of (1) integrating the profile curves using circular apertures, and (2) approximating an ``equivalent circular'' galaxy that is highly elongated by using an ``effective'' radius of sqrt{ab}, where a and b are the semi-major and semi-minor axis, respectively, of the best-fitting ellipse. The conclusion is that the two methods of reduction give nearly identical results and that either method can be used to analyze the low and high-redshift galaxy samples used in the Tolman test.Comment: 15 pages, 9 figures; accepted for publication in Astronomical Journa

Keck Spectroscopy of the Gravitational Lens System PG 1115+080: Redshifts of the Lensing Galaxies

The quadruple system PG 1115+080 is the second gravitational lens with a reported measurement of the Hubble constant. In addition to the primary lens, three nearby galaxies are believed to contribute significantly to the lensing potential. In this paper we report accurate redshifts for all four galaxies and show that they belong to a single group at z_d = 0.311. This group has very similar properties to Hickson's compact groups of galaxies found at lower redshifts. We briefly discuss implications for the existing lens models and derive H_0 = 52 +/- 14 km/s/Mpc.Comment: revised to use the updated model of Keeton & Kochanek (astro-ph/9611216) and to correct the velocity dispersion of the group; 10 pages including 2 eps figures and 2 tables.
