We develop a logic of normative ability, as an extension to the Alternating-time Temporal Logic (ATL) of Alur, Henzinger, and Kupferman. While conventional ATL contains cooperation modalities of the form 〈〈C〉〉φ, intended to express the fact that coalition C have the capability to bring about φ, in Normative ATL* (NATL*), these expressions are replaced with constructs of the form 〈〈η : C〉〉φ, wit...

BACKGROUND The fact that HIV prevention often deals with politicised sexual and drug taking behaviour is well known, but structural HIV prevention interventions in particular can involve alteration of social arrangements over which there may be further contested values at stake. As such, normative frameworks are required to inform HIV prevention decisions and avoid conflicts between social goal...

Recently, there is increased attention to the integration of moral values into the conception, design, and development of emerging IT. The most reviewed approach for this purpose in ethics and technology so far is Value-Sensitive Design (VSD). This article considers VSD as the prime candidate for implementing normative considerations into design. Its methodology is considered from a conceptual,...

In 2001 Carlsson and Fullér introduced the possibilistic mean value, variance and covariance of fuzzy numbers. In 2002 Fullér and Majlender introduced the notations of crisp weighted possibilistic mean value, variance and covariance of fuzzy numbers, which are consistent with the extension principle. In this paper we will show some (normative) properties of possibility distributions.

This article suggests that fact checking is a useful but incomplete framework for delivering an epistemically healthy public sphere. Through brief history of the fact/value distinction, it argued there no secure justification limiting interventions aimed at improving emergent digital sphere only to factual claims. On this basis, heuristic principle ‘value checking’ outlined, as complement in ep...

in his perspective “navigating between stealth advocacy and unconscious dogmatism: the challenge of researching the norms, politics and power of global health,” ooms argues that actions taken in the field of global health are dependent not only on available resources, but on the normative premise that guides how these resources are spent. this comment sets out how the application of a predomina...
