Today\u27s Electronic Communication Facilitators: A Profile of Fortune 1000 Webmasters
This profile of Webmasters of Fortune 1000 companies is based on electronic mail survey responses. In general, the people who hold the webmaster title or position within these large organizations are very satisfied with their jobs, are fairly young, and are highly educated although the disciplines of their academic backgrounds are considerably diverse. The Webmasters are also very interested in the characteristics of their professional counterparts in other large organizations. Beyond the demographics, this paper highlights Webmaster perceptions relative to the creation and use of home pages
Student Recognition and Awareness of Information Security in Course Learning from Management Information Systems and Computer Science Classes: An Empirical Investigation
A survey of college students from both IS and CS programs was undertaken to understand student recognition and awareness of information security issues in course learning. Comparisons will be made for students before and after taking the security class as well as between the two different majors. The results of the study will demonstrate possible differences in perceptions between students of two majors, and identify security issues which have not been identified so that students and institutions are able to improve academic achievements by better tailored security curriculum and training. The findings will also provide feedback to future employers of the students

CIO/CTO Job Roles: An Emerging Organizational Model
The position of Chief Information Systems Officer (CIO) has become a daunting job due to the myriad of business and technical responsibilities assigned to the organization\u27s top information systems (IS) executive. CIOs are being asked to successfully ensure the firm\u27s IS investments are continually aligned with its strategic business objectives, while also planning and maintaining an IT infrastructure that will meet the firm\u27s current and future information processing needs. Many CIOs are finding it extremely difficult to balance the two key roles of technician and businessperson successfully. Many business experts that have analyzed this problem have concluded that the tasks and responsibilities assigned to a typical CIO may be too overwhelming for a single person. This paper advances a formal organizational structure in which the typical responsibilities of the CIO position are re-allocated to two IS executives - the CIO and the Chief Technology Officer (CTO). This paper also describes which responsibilities should be retained by the CIO and which responsibilities should be delegated to the CTO. Finally, a discussion of the challenges and benefits associated with the implementation of CIO/CTO organizational leadership structure is presented
Tablet PCs for Teaching Information Systems Courses
The authors describe integration of and multiple uses for the tablet PC (TPC) in MIS classes. These uses are geared toward enhancing student learning through the TPC rather than learning how to use a specific tool. These technologies are used in a database course and an information security course to enhance student learning by having students participate in drawing entity relationship diagrams (ERD) and network configurations. Digital documents, annotated with digital ink are exchanged between faculty and students. A survey is used to capture perceptions of MIS majors regarding the value of the TPC in these two courses. These results are then compared and contrasted with results that have been previously published for TPCs in a database course. Results indicate that a major issue facing educators is the lack of critical mass in the adoption of TPCs by students
Securing Personal Information Assets: Testing Antecedents of Behavioral Intentions
Due to the increased global reliance on information technology, and the prominence of information resources value, identity theft is a problem domain effecting millions of computer users annually. The realities of identity theft are highly visible in the global media, although empirical investigations on the topic are limited. The purpose of this study is to identify and analyze perceptions of personal information (e.g., identity) as it relates to perceived threats, mitigation, perceived risks, and intended safe information practice intentions. We propose a risk analysis model based on theoretical variables that have been researched and extensively used in both government and private sector organizations. The model is empirically tested using LISREL to perform structural equation modeling. Findings indicate support for a relationship between risk and both 1) behavioral intentions to perform safe information practices and 2) personal information asset value
LSST Science Book, Version 2.0
A survey that can cover the sky in optical bands over wide fields to faint
magnitudes with a fast cadence will enable many of the exciting science
opportunities of the next decade. The Large Synoptic Survey Telescope (LSST)
will have an effective aperture of 6.7 meters and an imaging camera with field
of view of 9.6 deg^2, and will be devoted to a ten-year imaging survey over
20,000 deg^2 south of +15 deg. Each pointing will be imaged 2000 times with
fifteen second exposures in six broad bands from 0.35 to 1.1 microns, to a
total point-source depth of r~27.5. The LSST Science Book describes the basic
parameters of the LSST hardware, software, and observing plans. The book
discusses educational and outreach opportunities, then goes on to describe a
broad range of science that LSST will revolutionize: mapping the inner and
outer Solar System, stellar populations in the Milky Way and nearby galaxies,
the structure of the Milky Way disk and halo and other objects in the Local
Volume, transient and variable objects both at low and high redshift, and the
properties of normal and active galaxies at low and high redshift. It then
turns to far-field cosmological topics, exploring properties of supernovae to
z~1, strong and weak lensing, the large-scale distribution of galaxies and
baryon oscillations, and how these different probes may be combined to
constrain cosmological models and the physics of dark energy.Comment: 596 pages. Also available at full resolution at

The Afterglows of Swift-era Gamma-Ray Bursts II.: Type I GRB versus Type II GRB Optical Afterglows
We use a large sample of GRB afterglow and prompt-emission data (adding
further GRB afterglow observations in this work) to compare the optical
afterglows (or the lack thereof) of Type I GRBs with those of Type II GRBs. In
comparison to the afterglows of Type II GRBs, we find that those of Type I GRBs
have a lower average luminosity and show an intrinsic spread of luminosities at
least as wide. From late and deep upper limits on the optical transients, we
establish limits on the maximum optical luminosity of any associated supernova,
confirming older works and adding new results. We use deep upper limits on Type
I GRB optical afterglows to constrain the parameter space of possible mini-SN
emission associated with a compact-object merger. Using the prompt emission
data, we search for correlations between the parameters of the prompt emission
and the late optical afterglow luminosities. We find tentative correlations
between the bolometric isotropic energy release and the optical afterglow
luminosity at a fixed time after trigger (positive), and between the host
offset and the luminosity (negative), but no significant correlation between
the isotropic energy release and the duration of the GRBs. We also discuss
three anomalous GRBs, GRB 060505, GRB 060614, and GRB 060121, in the light of
their optical afterglow luminosities. (Abridged)Comment: Re-submitted to ApJ; 56 pages in emulateapj format; strongly expanded
