Privacy risks have been addressed through technical solutions such as privacy-enhancing technologies (PETs) as well as regulatory measures including Do Not Track. These approaches are inherently limited as they are grounded in the paradigm of a rational end user who can determine, articulate, and manage consistent privacy preferences. This implies that self-serving efforts to implement individu...

Dois tetranortriterpenos, sendo um inédito e dois novos derivados do acido dihidrocinâmico foram obtidos da madeira de Hortia colombiana. Suas estruturas foram elucidadas por RMN, e as configurações relativas estabelecidas através de experimentos de nOe diferencial. Em adição, foram isolados aloxantoxiletina, nerolidol, epoxinerolidol, três conhecidos derivados do acido dihidrocinâmico e duas a...

It has been recognized that a framework based on proofcarrying code (also called semantic-based software certification in its community) could be used as a candidate software certification process for the avionics industry. To meet this goal, tools in the “trust base” of a proof-carrying code system must be qualified by regulatory authorities. A family of semantic-based software certification a...

Patients with do-not-resuscitate (DNR) orders may elect to have palliative surgery. Should DNR orders be automatically suspended in the operating room (OR)? This article addresses the following issues: (1) Ethics of DNR orders. (2) The American Society of Anesthesiology's Ethical Guidelines for the Anesthesia Care of Patients with Do-Not-Resuscitate Orders or Other Directives that Limit Treatme...

Prescriptive process-based safety standards (e.g. EN 50128, DO-178B, etc.) incorporate best practices to be adopted to develop safety-critical systems or software. In some domains, compliance with the standards is required to get the certificate from the certification authorities. Thus, a well-defined interpretation of the processes to be adopted is essential for certification purposes. Current...
