Penetration testing entails attacking a system to identify and report insecurity, but doing so without harming the system nor encroaching on the dignity of those affected by it. To improve the interaction between penetration testers and their processes and technology, we need to understand the factors that affect decisions they make with ethical import. This paper presents four ethical hazards ...

This paper reports about the analysis of the Internet diffusion among families and business basing on daily observations on registrations of second level domain names underneath the “.it” ccTLD . In particular, domains registered by individuals are analysed. The penetration rate over the relevant population of potential adopters is computed at highly disaggregated geographical level (province)....

I. The basic example A0 (Figure 1). A regular normed projection of our basic example of a mildly wild non-Wilder arc is shown in Figure 1. (Using the methods of [4], one could easily give a precise description.) (A) Ao is not L.P.U. at p. The invariants of [7] will be used to show that the penetration index PiA0, p) of A0 at p is equal to 4. (For a definition of the penetration index see [l] an...

We present experiments to predict the maximum penetration depth atwhich typical biological structures in amelanotic tissue can bedetected with confocal microscopy. The detected signal is examinedas the signal source strength (index of refraction mismatch), thesource depth, and the medium scattering coefficient are varied. Thedetected background produced by scattering outside the focal volume is...

The ability of domestic cat or leopard cat spermatozoa to penetrate zonae pellucidae (ZP) of salt-stored, domestic cat oocytes was examined as an assay for sperm capacitation. Ovarian oocytes were recovered after ovariectomy and matured in vitro for 18-36 h. Following removal of cumulus cells, the oocytes were used fresh, or stored (4°C, 0.5-24 weeks) in a HEPES-buffered hypertonic salt solutio...

Cooperative ITS is enabling vehicles to communicate with the infrastructure to provide improvements in traffic control. A promising approach consists in anticipating the road profile and the upcoming dynamic events like traffic lights. This topic has been addressed in the French public project Co-Drive through functions developed by Valeo named Green Light Optimal Speed Advisor (GLOSA). The sys...

We estimate the effect of Internet on volume of trade in a major distributed marketplace. From 1997 to 2007, a period during which residential Internet use tripled, Internet increased the volume of used cars traded in California by 7.2 percent. This implies a substantial welfare gain due to reductions in market frictions of approximately $43 million per year relative to 1997 Internet penetratio...
