An Examination of Cybersecurity Knowledge Transfer: Teaching, Research, and Website Security at U.S. Colleges and Universities

This work seeks to answer the question: Does faculty cybersecurity knowledge gained from teaching and research transfer to other IT units in the university? Specifically, do colleges and universities that excel in cybersecurity teaching and research have more secure websites? This work explores a unique setting where the knowledge of the source and recipient are both directly related and observable without outside intervention. Our study employed data from 591 U.S. colleges and universities, the National Centers of Academic Excellence (CAE) program, accepted paper data from the ACM Conference on Computer and Communications Security (CCS) and the IEEE Symposium on Security and Privacy (SSP), as well as the results from the SSL Labs Server Test. Our data suggest that universities with cybersecurity research excellence receive higher grades for website security. However, university website security is not significantly associated with cybersecurity teaching excellence, institution size or tuition costs

Incorporating ASP.Net in an Information Systems Curriculum

The challenge of providing information systems graduates with the optimal balance between the old and new technology is a constantly evolving process. This teaching tip introduces Microsoft\u27s ASP.NET technology, which can be used as a bridge to integrate mainframe and client/server technologies. In order to maximize the benefits of using ASP.NET, students need to understand and apply the interrelated concepts of Windows XP professional security system, the Web Server structure, and the .Net Visual Studio setup routine for the development environment

A state-level study of opioid use disorder treatment access and neonatal abstinence syndrome

Background Adult opioid use and neonatal abstinence syndrome (NAS) are growing public health problems in the United States (U.S.). Our objective was to determine how opioid use disorder treatment access impacts the relationship between adult opioid use and NAS. Methods We conducted a cross-sectional state-level ecologic study using 36 states with available Healthcare Cost and Utilization Project State Inpatient Databases in 2014. Opioid use disorder treatment access was determined by the: 1) proportion of people needing but not receiving substance use treatment, 2) density of buprenorphine-waivered physicians, and 3) proportion of individuals in outpatient treatment programs (OTPs). The incidence of NAS was defined as ICD-9 code 779.5 (drug withdrawal syndrome in newborn) from any discharge diagnosis field per 1000 live births in that state. Results Unmet need for substance use disorder treatment correlated with NAS (r = 0.54, 95% CI: 0.26–0.73). The correlation between adult illicit drug use/dependence and NAS was higher in states with a lower density of buprenorphine-waivered physicians and individuals in OTPs. Conclusions Measures of opioid use disorder treatment access dampened the correlation between illicit drug use/dependence and NAS. Future studies using community- or individual-level data may be better poised to answer the question of whether or not opioid use disorder treatment access improves NAS relative to adult opioid use

Grain boundary energies and cohesive strength as a function of geometry

Cohesive laws are stress-strain curves used in finite element calculations to describe the debonding of interfaces such as grain boundaries. It would be convenient to describe grain boundary cohesive laws as a function of the parameters needed to describe the grain boundary geometry; two parameters in 2D and 5 parameters in 3D. However, we find that the cohesive law is not a smooth function of these parameters. In fact, it is discontinuous at geometries for which the two grains have repeat distances that are rational with respect to one another. Using atomistic simulations, we extract grain boundary energies and cohesive laws of grain boundary fracture in 2D with a Lennard-Jones potential for all possible geometries which can be simulated within periodic boundary conditions with a maximum box size. We introduce a model where grain boundaries are represented as high symmetry boundaries decorated by extra dislocations. Using it, we develop a functional form for the symmetric grain boundary energies, which have cusps at all high symmetry angles. We also find the asymptotic form of the fracture toughness near the discontinuities at high symmetry grain boundaries using our dislocation decoration model.Comment: 12 pages, 19 figures, changed titl

Accurate masses for dispersion-supported galaxies

We derive an accurate mass estimator for dispersion-supported stellar systems and demonstrate its validity by analyzing resolved line-of-sight velocity data for globular clusters, dwarf galaxies, and elliptical galaxies. Specifically, by manipulating the spherical Jeans equation we show that the dynamical mass enclosed within the 3D deprojected half-light radius r_1/2 can be determined with only mild assumptions about the spatial variation of the stellar velocity dispersion anisotropy. We find M_1/2 = 3 \sigma_los^2 r_1/2 / G ~ 4 \sigma_los^2 R_eff / G, where \sigma_los^2 is the luminosity-weighted square of the line-of-sight velocity dispersion and R_eff is the 2D projected half-light radius. While deceptively familiar in form, this formula is not the virial theorem, which cannot be used to determine accurate masses unless the radial profile of the total mass is known a priori. We utilize this finding to show that all of the Milky Way dwarf spheroidal galaxies (MW dSphs) are consistent with having formed within a halo of mass approximately 3 x 10^9 M_sun in Lambda CDM cosmology. The faintest MW dSphs seem to have formed in dark matter halos that are at least as massive as those of the brightest MW dSphs, despite the almost five orders of magnitude spread in luminosity. We expand our analysis to the full range of observed dispersion-supported stellar systems and examine their I-band mass-to-light ratios (M/L). The M/L vs. M_1/2 relation for dispersion-supported galaxies follows a U-shape, with a broad minimum near M/L ~ 3 that spans dwarf elliptical galaxies to normal ellipticals, a steep rise to M/L ~ 3,200 for ultra-faint dSphs, and a more shallow rise to M/L ~ 800 for galaxy cluster spheroids.Comment: 20 pages, 13 figures.

Enhancing IS Education with Flexible Teaching and Learning

Flexible teaching and learning is not a new concept, but it is one that we, as educators, do not focus on enough. Designing and delivering innovative, exciting and relevant learning experiences is needed if we are to make our classes good learning experiences. Information systems (IS) educators deal with technology every day, yet we are sometimes the first ones to forget how to use it in the classroom. Educators must recognize the importance of increasing student control over and active participation in their own learning. This Special Issue of the Journal of Information Systems Education looks at flexible teaching and learning in the IS classroom. We present eight papers on flexible teaching and learning, dealing with both the face-to-face and online classroom environments. We hope that the ideas presented in these papers will foster your thinking in using flexible teaching techniques. In the end, flexible teaching and learning focuses on improving student learning, a goal that we all aspire to in our classrooms
