Revelation in Discovery

The green and amber patches of grass stretch from the sedate black enameled fence which envelopes the front yard to the sturdy, but well-loved back yard fence. This wrought iron guardian is fancifully decorated with sprigs of greenery and a few red berries which impart to it just a touch of dignified color and give the passerby an impression of loftiness. For it is the sentinel which stands guard against all intruders who might trespass into the private domain of liquid green velvet expanse

Prioritizing IT Projects: An Empirical Application of an IT Investment Model

Information Technology projects are organizational investments that anticipate positive returns. When viewed as such, the development of a diversified “portfolio” of projects helps reduce risk from a single project failure, and results in an overall positive return. Positive returns on IT projects are usually indirect, since they have value only insomuch as they enable the accomplishment of larger organizational goals. We present here a model that integrates elements of risk, cost, and internal rate of return that can be applied to individual IT projects. The model produces a numerical score that can be used to rank potential IT projects. Projects with higher scores return more value to the organization, and therefore should be given a higher priority. We apply the model using the IT project portfolio of a large state-charterd credit union. The results indicated that the credit union was prioritizing projects with more visibility but lower returns that other projects with less visibility but that offered greater returns. The implications of applying the model in other organizational settings are discussed

DECam Survey for Low-Mass Stars and Substellar Objects in the UCL and LCC Subgroups of the Sco-Cen OB Association (SCOCENSUS)

Using images taken with the Dark Energy Camera (DECam), the first extensive survey of low mass and substellar objects is made in the 15-20 Myr Upper Centaurus Lupus (UCL) and Lower Centaurus Crux (LCC) subgroups of the Scorpius Centaurus OB Association (Sco-Cen). Due to the size of our dataset (>2Tb) we developed an extensive open source set of python libraries to reduce our images, including astrometry, coaddition, and PSF photometry. Our survey consists of 29$\times$3 deg$^2$ fields in the UCL and LCC subgroups of Sco-Cen and the creation of a catalog with over 11 million point sources. We create a prioritized list of candidate for members in UCL and LCC, with 118 \emph{best} and another 348 \emph{good} candidates. We show that the luminosity and mass functions of our low mass and substellar candidates are consistent with measurements for the younger Upper Scorpius subgroup and estimates of a universal IMF, with spectral types ranging from M1 down to L1.Comment: 26 pages, 27 figure

Fostering Change: Evaluating Digital Scholarship for Professional Credit

As the field of digital humanities becomes an ever more important facet of both research and teaching, we need to find means for ensuring that the work is properly evaluated and that credit is given to the scholars who engage in it. The problems associated with developing this are complex, and new modes of research and publication have proven difficult to incorporate into disciplines that have traditionally put high value on print. Scholarly societies have an important role to play in encouraging creative thought and action about how best to accommodate these new modes within our disciplines
