We describe the "evaluability bias": the tendency to weight the importance of an attribute in proportion to its ease of evaluation. We propose that the evaluability bias influences decision making in the context of charitable giving: people tend to have a strong preference for charities with low overhead ratios (lower administrative expenses) but not for charities with high cost-effectiveness (...

The notion of accountable authority introduced by Goyal (Crypto 2007) in identity-based encryption (IBE) setting is a novel approach to mitigate the (inherent) key escrow problem in identity based cryptosystems. As far as we know, the (inherent) key escrow problem also exists in attribute based encryption (ABE), for example ciphertext policy ABE (CP-ABE). In this paper, the concept of accountab...

Bluetooth technology is slowly becoming more popular but the security built into the specification is a cause for concern. More and more consumer products used in normal daily life are manufactured with Bluetooth systems such as cell phones, PDA's and mobile computers. It is important that consumers understand the technology and the risks involved in the use thereof. Some of those risks range f...

Apart from the spatial resolution enhancement, scaling of temporal resolution, equivalently the imaging throughput, of fluorescence microscopy is of equal importance in advancing cell biology and clinical diagnostics. Yet, this attribute has mostly been overlooked because of the inherent speed limitation of existing imaging strategies. To address the challenge, we employ an all-optical laser-sc...

We measured the absorption spectrum (340-640 nm) of the purest available water with photothermal deflection spectroscopy. Our spectrum exhibits an absorption minimum in the blue region of the spectrum that is deeper than in most previously documented pure-water absorption studies. We attribute this to exceptional sample purity and our technique's inherent freedom from scattering effects. Becaus...

In book 1 Thucydides’ Corinthians attribute Athenian military success in the Archidamian war to an inherent national character. They empahsize the characteristics of agility, speed, and common-good seeking. Thucydides’ readers come to realize that the Athenian “democratic advantage” stemmed from a superior capacity to organize useful knowledge. Knowledge management in military affairs can be le...
