In the domain of Linked Open Data a need is emerging for developing automated frameworks able to generate the licensing terms associated to data coming from heterogeneous distributed sources. This paper proposes and evaluates a deontic logic semantics which allows us to define the deontic components of the licenses, i.e., permissions, obligations, and prohibitions, and generate a composite lice...

This paper investigates the semantic treatment of conditional obligation, explicit permission (often called positive permission), and prohibition based on models with agents and branched time. In such models branches (rather than moments) are taken as basic, and the branching provides a way to represent the indeterminism which is normally presupposed by talk of free will, responsibility, action...

Coral reefs, one of the most biologically diverse and important ecosystems on Earth, are experiencing unprecedented and increasing ecological decline, yet the fish faunas of such reefs and other tropical shoreline habitats remain poorly known in many areas. Rotenone, a natural substance traditionally used by subsistence fishers, is a uniquely efficient tool for sampling reef and other shore fis...

We extend the logical model of agency known as the KGP model, to support agents with normative concepts, based on the roles an agent plays and the obligations and prohibitions that result from playing these roles. The proposed framework illustrates how the resulting normative concepts, including the roles, can evolve dynamically during the lifetime of the agent. Furthermore, we illustrate how t...

On the heels of extensive public and political debate, controversy and criticism, Bill C-56, An Act respecting assisted human reproduction, was introduced in the House of Commons on May 9, 2002. Through this bill, Parliament has proposed to regulate practices associated with reproductive technologies by relying on its criminal law jurisdiction. Certain scientific activities are altogether prohi...

Section I of this Note analyzes the cases in which the Commission and the Court of Justice have implied a doctrine of economic unity and argues that this economic unity exemption to the prohibitions of article 85 may indeed be a limited one. Section II sets forth the theoretical and practical difficulties that such a limited economic unity doctrine entails. Finally, section III presents an alte...

Thesis supervison can bring to light unresolved and new psychological issues for both supervisors and students. What makes thesis supervision especially difficult is that supervisors have no officiai mandate to deal with disruptive psychological processes. In fact, there are prohibitions against such interpersonal involvement. Those supervisors who move beyond the borders of traditional, ration...

OBJECTIVES To examine the salience of tobacco marketing on postsecondary campuses and student support for tobacco control policies. METHODS Face-to-face surveys were conducted with 1690 students at 3 universities in southwestern Ontario. RESULTS Virtually all (97%) students reported noticing tobacco marketing in the past year, and 35% reported noticing marketing on campus. There was strong ...

Although there have been cases of plastic surgery that date back to 2600 years ago, there has been a relatively recent upsurge in plastic surgery operations due to improved sterilization techniques and the advent of anesthesia [1]. Since plastic surgery operations were so rare until recently, teshuvos did not appear on the subject until about 60 years ago [1]. The topic of plastic surgery raise...

We propose an IDE – Integrated Development Environment to model SBVR (Semantic of Business Vocabulary and Business Rule) compliant business rules [2] extracted from business contract of services and store them in an ontological structure of rules, facts and terms as defined in the SBVR metamodel. Business rules are based on principles of deontic logic for treating expressions in the form of nor...
