A vertical refusal to deal arises when a dominant input supplier refuses to sell its input to downstream rivals. A complementary refusal to deal arises when the dominant supplier of one product sells that product to customers as part of a bundle but refuses to sell that product alone to a rival...

Controlled query evaluation preserves confidentiality in information systems at runtime. A security policy specifies the facts a certain user is not allowed to know. At each query, a censor checks whether the answer would enable the user to learn any classified information. In that case, the answer is distorted, either by lying or by refusal. We introduce a framework in which controlled query e...

Methods of calculation of thermal processes of the isolating materials are considered, in problems of nondestructive diagnostics of the main and distributive power stations. Theoretical justification of calculation of thermal processes of the multilayered isolating structure was given. On the basis of the analysis of results of operation, service life, physical processes of "ageing" and use of ...

Parental refusal of a recommended treatment is not an uncommon scenario in the neonatal intensive care unit. These refusals may be based upon the parents' perceptions of their child's projected quality of life. The inherent subjectivity of quality of life assessments, however, can exacerbate disagreement between parents and healthcare providers. We present a case of parental refusal of surgical...

A shared information system is expected to comply with the following potentially conflicting requirements. On the one side it should provide useful answers to arbitrary queries, while on the other side it should preserve certain secrets according to a security policy. We study and compare two previously suggested approaches to meet these requirements, namely refusal of statements and lying . Th...
