This paper describes the evolution of strategies to evaluate ePortfolios in an online Master’s of Education (M.Ed.) degree in Instructional Technology. The ePortfolios are required as a culminating activity for students in the program. By using Web 2.0 tools to develop the ePortfolios, students are able to showcase their technical skills, integrate national standards, demonstrate their professi...

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 ...

We present a proof-of-principle experiment in which the population of an atomic level is spatially localized using the technique of electromagnetically-induced transparency (EIT). The key idea is to utilize the sensitive dependence of the dark state of EIT on the intensity of the coupling laser beam. By using a sinusoidal intensity variation (standing-wave), we demonstrate that the population o...

A vacuum of public trust in Australia has met with the maturation of technologically competent constituents. Changing sociopolitical attitudes and perceived government corruption and inefficiency have effected demands for accountability and transparency. Two responses are visible: the digitisation of government services and original models of digital democracy. This paper discusses the role dis...

In this paper, we shed new light on the role of monetary policy in asset pricing by focusing on the case where investors have heterogeneous expectations about future monetary policy. This case is realistic, because central banks are typically less than perfectly open on their intentions. Accordingly, surveys of economists in the press reveal that they frequently disagree in their expectations. ...

Transparency is a complex issue, which can be approached from many angles and with various conceptual tools. This contribution provides a brief survey of the economic literature on transparency. The conceptual tool that economists use is the principal-agent model, a game-theoretic setting where a principal (the citizens, shareholders, etc) wants an agent (the government, the CEO, etc.) to perfo...
