Floridi ́s Theory of Strongly Semantic Information defines information as consisting of data and truth in contrast to the standard definition prevailing in empirical sciences in which information is defined as meaningful data. I argue that meaningful data does not necessarily need to be true to constitute information. Partially true information or even completely false information can lead to an...

How to define the security of undeniable signature schemes is a challenging task. This paper presents two security definitions of undeniable signature schemes which are more useful or natural than the existing definition. It then proves their equivalence. We first define the UC-security, where UC means universal composability. We next show that there exists a UC-secure undeniable signature sche...

We model unawareness of possibilities in decision-making and (linguistic) pragmatic reasoning. A background model is filtered through a state of limited awareness to provide the epistemic state of an agent who is not attending to all possibilities. We extend the standard notion of awareness with assumptions (implicit beliefs about propositions the agent is unaware of) and define a dynamic updat...

We present in this paper a comparison between three segmentation systems for the Vietnamese language. Indeed, the majority of Vietnamese words is built by semantic composition from about 7,000 syllables, that also have a meaning as isolated words. So the identification of word boundaries in a text is not a simple task, and ambiguities often appear. Beyond the presentation of the tested systems,...

This study investigates the relative influence of two formal features of video games—image quality and sound quality—on presence and enjoyment. A 2 x 2 between subjects experiment was conducted manipulating image quality (high definition vs. standard definition) and sound quality (Dolby 5.1 surround sound vs. Dolby stereo). Results indicated that, while image quality had no effect on outcomes, ...

The standard definition of neighborhood density defines two words to be neighbors if they differ by one and only one segment (Luce & Pisoni, 1998). This definition assumes that the length of the shared part is irrelevant to sound similarity. However, confusability of non-linguistic sound sequences (Fallon Coble & Robinson, 1992; Kidd & Watson, 1992) as well as judgments of sound similarity betw...

Using a standard definition of productivity growth, it is shown that a country may have higher productivity growth than another country in each sector, but may have a lower productivity growth rate overall. Also, it is shown that popular methods for aggregating firm/industry estimates of productivity growth have a serious problem in that productivity of all firms/industries can go up, but aggre...

This paper argues that the introduction of a short-sale constraint in the ArrowRadner framework invalidates standard definitions of complete and incomplete markets. In this constrained set-up, two threshold values with familiar properties arise. The case of a zero short-sale bound set on some security fulfills the standard definition of “incomplete” financial markets. Beyond a particular level ...
