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...

We calculate the line shape and linewidths for electromagnetically induced transparency EIT in optically thick, Doppler broadened media buffer gasses are also considered . In generalizing the definition of the EIT linewidth to optically thick media, we find two different linewidth definitions apply depending on whether the experiment is pulsed or continuous wave cw . Using the cw definition for...

We investigated whether students liked and learned more from PowerPoint presentations than from overhead transparencies. Students were exposed to lectures supported by transparencies and two different types of PowerPoint presentations. At the end of the semester, students preferred PowerPoint presentations but this preference was not found on ratings taken immediately after the lectures. Studen...

Add a stage of signal acquisition to a canonical model of portfolio choice. Under fully revealing asset price, investors’ information demand reflects their choice of transparency. In reducing uncertainty, financial transparency raises expected asset price and thus benefits holders of the risky asset. At a natural transparency limit, however, investors pay to inhibit further disclosure in order ...
