Since the 2000s, large fluctuations in commodity prices have become a concern among policymakers regarding price stability. This paper investigates the effects of commodity price shocks on headline inflation with a monthly panel consisting of 144 countries. We find that the effects of commodity price shocks on inflation virtually disappear within about one year after the shock. While the effect...

Since the middle of the twentieth century, the problem of making inferences about the point in a surveyed series of observations at which the underlying distribution changes has been extensively addressed in the economics, biostatistics and statistics literature. CUSUM type statistics have commonly been thought to play a central role in non-sequential change point detections. Alternatively, we ...

headline 22.1 Of the 141 Certain/probable and Possible cases, only 12 (11%) submitted a formal complaint to the hospital and a further 8 (6%) were reported to be involved in some legal action. Of the 17 Drug Error cases (where clearly error led to the AAGA and care was judged poor), just one patient submitted a formal complaint (6%) and one separate (6%) patient commenced legal proceedings. Of ...

We (Fu, Dienes, & Fu, 2010) investigated the extent to which people could generate sequences of responses based on knowledge acquired from the Serial Reaction Time task, depending on whether it felt subjectively like the response was based on pure guessing, intuition, conscious rules or memories. Norman and Price (2010) argued that in the context of our task, intuition responses were the same a...

We discuss how we use neural networks to accurately measure password strength, and how we use this capability to build effective password meters. First, we show how neural networks can be used to guess passwords and how we leveraged this method to build a password guesser to better model guessing attacks. We report our measurements of the effectiveness of neural networks at guessing passwords, ...

Rapid guessing is a test taking strategy recommended for increasing the probability of achieving high score if time limit prevents an examinee from responding to all items scale. The requires quickly and without cognitively processing item details. Although there may be no omitted responses after participants' rapid guessing, open question remains: d...

Online password guessing attacks are a serious threat to the integrity of online accounts. A common defense is ratelimiting, either by slowing down or blocking connections, or by requiring CAPTCHAs to be solved. Either of these options has serious drawbacks, facilitating denial of service attacks, being circumventable by proxies and CAPTCHA solving services, and offering bad usability to the le...
