In this paper, we present a variant of Datalog language (we call it Datalog ) able to deal with weights on ground facts and to consequently compute a feedback result for the goal satisfaction. The weights are chosen from a proper c-semiring. In our context, our goal is to use this language as a semantic foundation for languages for expressing trust relationships. As a matter of fact, many of th...

Sharing sensitive information across security domains is an important requirement for knowledge intensive collaborative work, but such sharing may impose risks on security and privacy integrity. Research has increasingly recognized the role of trust in minimizing the risk of information sharing across untrusted or unknown entities. To this extent, trust negotiations[1][3][15][20] have emerged a...

Grounded Theory provides a useful approach for eliciting and justifying subjective characteristics of individuals. A Grounded Theory analysis is carried on individuals who share pictures, with a view to developing a trust management policy model of indiscretion regarding the sharing of photographs.

Both agents allow customers to post reviews on hotels, but only one of the travel agents allows hotel management to post managerial responses. Using a difference-in-difference approach, we find that managerial responses h...

We find that firms with ‘low’ and ‘high’ levels of managerial ownership experience positive relationships between managerial ownership and the change in performance (alignment-...

This paper provides direct evidence that managerial style is a key determinant of the firm’s cost of capital, in the context of private debt contracting. Applying the novel empirical method by Abowd, Karmarz, and Margolis (1999) to a large sample that tracks job movement of top managers, we find that managerial style is a critical factor that explains a large part of the variation in loan contr...

We present a formal model of how the size of a firm’s administrative staff depends on the environment in which it operates. We consider a monopolist that introduces a new product in the face of market uncertainty. In a model that incorporates an informationprocessing view of the managerial hierarchies into a product choice problem, we relate optimal size of organizations to the speed of change ...
