This paper explores how regulatory relationships in the global audit arena are being affected by the current financial crisis. Key policy initiatives and debates are analyzed, along with institutional interactions, in particular between the International Federation of Accountants (IFAC), international regulators and the large audit firms. The events are placed in the context of the new international financial architecture which has developed over the last decade. Using the illustrative lens of bank auditing, questions are asked of the nature and status of audit practice and the regulatory arrangements governing such practice. The paper shows the active nature of the regulatory responses to the crisis and the shifting and competing influences among key regulatory and professional participants in the global audit arena. Emphasis is placed on the need for audit researchers to be sensitive to the developing global financial architecture, and its potential implications for the study of audit practice in different national and international contexts.

In this paper we provide evidence for the effects of social norms on audit pricing by studying companies belonging to the alcohol, firearms, gambling, military, nuclear power, and tobacco industries,which are often described as “sin” companies. We hypothesize that the disparities between “sin” firms operations and prevailing social norms create an adverse context which heightens the client's business risk assessment by auditors and is, thereby, reflected in the pricing decisions for audit and consulting services. Having controlled for the impact of variables relating to client attributes, auditor attributes and engagement attributes, we demonstrate that audit firms charge significantly higher audit and consulting fees to companies that deviate from prevailing social norms. Additionally,we show that audit pricing levels within the “sin” group depend both on prevailing political views and on the level of “vice” exhibited by “sin” companies.

This paper investigates the associations between audit pricing and multidimensional characteristics of local governments by using a sample of Greek municipalities. The Greek institutional setting is interesting because it is politically pluralistic. Moreover, independent auditors appointed through a bid process exclusively perform the audits. Our results suggest a considerable variation on audit fees which is mainly driven by politically related factors indicating the importance of relevant theoretical anticipations in audit pricing in the public sector. Agency costs appear strong enough to explain audit pricing. We also confirm prior findings on the significance of audit complexity and size. Results also suggest that audit fees are reduced when an internal team dedicated to accrual accounting is appointed. Therefore, our conclusions offer practical implications for policy setters and regulators in the public sector in relation to audit quality.

Ambulatory electroencephalogram has been used for differentiating epileptic from nonepileptic events, recording seizure frequency and classification of seizure type. We studied 100 consecutive children prospectively aged 11 days to 16 years that were referred for an ambulatory electroencephalogram to a regional children's hospital. Ambulatory electroencephalogram was clinically useful in contributing to a clinical diagnosis in 71% of children who were referred with a range of clinical questions. A diagnosis of epileptic disorder was confirmed by obtaining an ictal record in 26% and this included 11 children that had previously normal awake and or sleep electroencephalogram. We recommend making a telephone check of the current target event frequency and prioritising those with typical events on most days in order to improve the frequency of recording a typical attack.

In traditional communication systems the transmission medium is considered as a given characteristic of the channel, which does not depend on the properties of the transmitter and the receiver. Recent experimental demonstrations of the feasibility of extending the laser cavity over the whole communication link connecting the two parties, forming an ultra-long fiber laser (UFL), have raised groundbreaking possibilities in communication and particularly in secure communications. Here, a 500 km long secure key distribution link based on Raman gain UFL is demonstrated. An error-free distribution of a random key with an average rate of 100 bps between the users is demonstrated and the key is shown to be unrecoverable to an eavesdropper employing either time or frequency domain passive attacks.

With the European Commission making global leadership claims in the field of audit regulation, the content of its 2010 Green Paper on ‘Audit Policy: Lessons from the Crisis’ warrants careful scrutiny. Important issues raised in the Green Paper include regulatory oversight, competition in the audit market, the dangers of having very few firms with the capacity to audit global transnational corporations, professional judgement, innovative audit practices and, last but not least, social responsibility. This article analyses the principal perspectives and assumptions underpinning the construction of the Green Paper. The aims are threefold: to enhance understanding of the contemporary regulatory mindset of the European Commission, contribute to policy debate and inspire future research.

OBJECTIVE - To establish whether auditing improves the overall quality of a hospital manufacturing unit. DESIGN - Continuous assessment of the quality level of a hospital manufacturing unit using 14 quality indicators over a nine-month period, and two periods of audit carried out towards the beginning and end of the assessment period. SETTING - The non-sterile manufacturing, sterile manufacturing and repackaging services areas at the pharmacy manufacturing unit at Queens Hospital, Burton-on- Trent. RESULTS - Compliance ratings for the second audit were better than those for the first audit, but there was no overall improvement in quality over the study period. CONCLUSION - Auditing probably improves compliance by focusing the minds of the staff involved, rather than by initiating a sustained improvement in overall quality.

The abolition of the Audit Commission in England raises questions about how a major reform was achieved with so little controversy, why the agency lacked the institutional stickiness commonly described in the literature on organisational reform and why it did not strategise to survive. In this paper, we apply argumentative discourse analysis to rich empirical data to reveal the pattern and evolution of storylines and discourse coalitions, and the ways in which these interact with and affect the practices of Parliament, the media and the Audit Commission itself. Our analysis shows that the politics of administrative reform are as much about discursive framing and the ability of pro-reformers to gain discursive structuration and institutionalisation as they are about the material resources available to a newly elected government and its ministers. Questions of technical feasibility are unlikely to derail a reform initiative once its promoters gain discursive ascendency.

The distribution of the secret key is the weakest link of many data encryption systems. Quantum key distribution (QKD) schemes provide attractive solutions [1], however their implementation remains challenging and their range and bit-rate are limited. Moreover, practical QKD systems, employ real-life components and are, therefore, vulnerable to diverse attack schemes [2]. Ultra-Long fiber lasers (UFLs) have been drawing much attention recently because of their fundamentally different properties compared to conventional lasers as well as their unique applications [3]. Here, we demonstrate a 100Bps, practically secure key distribution, over a 500km link, employing Raman gain UFL. Fig. 1(a) depicts a schematic of the UFL system. Each user has an identical set of two wavelength selective mirrors centered at l0 and l 1. In order to exchange a key-bit, each user independently choose one of these mirrors and introduces it as a laser reflector at their end. If both users choose identical mirrors, a clear signal develops and the bits in these cases are discarded. However if they choose complementary mirrors, (1, 0 or 0, 1 states), the UFL remains below lasing threshold and no signal evolves. In these cases, an eavesdropper can only detect noise and is unable to determine the mirror choice of the users, where the choice of mirrors represent a single key bit (e.g. Alice's choice of mirror is the key-bit). These bits are kept and added to the key. The absence of signal in the secure states faxilitates fast measurements to distinguish between the non-secure and the secure states and to determine the key-bit in the later case, Sequentially reapeating the single bit exchange protocol generate the entire keys of any desirable length. © 2013 IEEE.

A retrospective analysis of 77 patients who presented with ODH at DR screening in the Birmingham And Black Country Screening Programme between June 2009 -March 2010. Of 77 detected, 34 were referred with possible glaucoma and this was confirmed in 11 cases (26%) of those referred. The complete results suggest that ODH is a high indicayor for glaucoma but that differing morphology of ODH is not a major predictor.
