Certificate transparency (CT) is an elegant mechanism designed to detect when a certificate authority (CA) has issued a certificate incorrectly. Many CAs now support CT and it is being actively deployed in browsers. However, a number of privacy-related challenges remain. In this paper we propose practical solutions to two issues. First, we develop a mechanism that enables web browsers to audit ...

BACKGROUND Licensed physicians in Alberta are required to participate in the Physician Achievement Review (PAR) program every 5 years, comprising multi-source feedback questionnaires with confidential feedback, and practice visits for a minority of physicians. We wished to identify and classify issues requiring change or improvement from the family practice visits, and the responses to advice. ...

If an antitrust authority chooses policies to maximize the number of successfully prosecuted cartels, when do those policies also serve to minimize the number of cartels that form? When the detection and prosecution of cartels is inherently difficult, we find that an antitrust authority’s policies minimize the number of cartels, as is socially desirable. But when the detection and prosecution o...

An attribute based encryption scheme (ABE) is a cryptographic primitive in which every user is identified by a set of attributes, and some function of these attributes is used to determine the ability to decrypt each ciphertext. Chase proposed the first multi authority ABE scheme in TCC 2007 as an answer to an open problem presented by Sahai and Waters in EUROCRYPT 2005. However, her scheme nee...

The link structure of the web is analyzed to measure the authority of pages, which can be taken into account for ranking query results. Due to the enormous dynamics of the web, with millions of pages created, updated, deleted, and linked to every day, timeliness of web pages and links is a crucial factor for their evaluation. Users are interested in important pages (i.e., pages with high author...

Authority is best defined as a relation that exists between individuals. A relation of authority exists when one individual, prompted by his or her circumstances, does as indicated by another individual what he or she would not do in the absence of such indication. This I will refer to as the authority relation. The legitimacy of an authority relation is what keeps the relationship from breakin...

The proposal that psychologists should pursue prescriptive authority was first put forth 25 years ago, and it has been an official goal of the American Psychological Association for 15 years. Since then some form of prescriptive authority has been approved by three states, the Territory of Guam, and three branches of the military. Psychologists are also eligible to prescribe in the Public Healt...

I describe the formation and functions of health authorities in British Columbia (BC) in general and VIHA in particular. I also address the initiatives VIHA undertook in support of its strategi...

Teacher authority has long been recognized as one of the critical factors that contribute to the formation of effective learning circumstances (Haywood-Metz, 2006). A survey was developed based on Dornbusch and Scott’s (1975) theoretical framework of distinction between formal authority and informal authority, named The Attitude towards College Instructor Authority (ACIA). By using this survey ...
