Materiality Thresholds in Accounting and Auditing Some UK Evidence

This paper reports the telephone interviews with 12 auditors (Big 5 and non Big 5) and 14 non auditors on the materiality thresholds adopted by them or by their organisations. Non auditors include from finance directors, banker, lawyer, internal auditors, an academic, and technical directors of the Accounting Standards Board (ASB) and the Auditing Practices Board (APB) in the UK. This is in respond to the issuance of Statement of Auditing Standards (SAS) 220 on ‘Materiality and the Audit= by the APB in 1995 whereby no materiality threshold was specifically mentioned. The findings showed that 10% of net profit before tax is the favourite threshold. This is close to recommendations from literature or due to influences by the literature themselves. A specific mathematical guideline could enhance harmonisation of reporting and interpretation of financial results

A convergent synthetic route to the tunicamycin antibiotics. Synthesis of (+)-tunicamycin V

The tunicamycins are a family of natural products represented generally by structure 1, wherein R indicates one of several long-chain branched, linear, saturated or unsaturated acyl substituents. They elicit a considerable range of biological responses including antimicrobial, antifungal, antiviral, and antitumor activities. Their ability to function as potent inhibitors of oligosaccharide synthesis in eukaryotic cells has established them as unique biochemical probes of the role of glycosylation on protein structure and function. In this work, we describe a concise synthetic route to the tunicamycins, illustrated by the preparation of (+)-tunicamycin V (1-V)

Solution of the Roth-Marques-Durian Rotational Abrasion Model

We solve the rotational abrasion model of Roth, Marques and Durian (arXiv:1009.3492), a one-dimensional quasilinear partial differential equation resembling the inviscid Burgers equation with the unusual feature of a step function factor as a coefficient. The complexity of the solution is primarily in keeping track of the cases in the piecewise function that results from certain amputation and interpolation processes, so we also extract from it a model of an evolving planar tree graph that tracks the evolution of the coarse features of the contour.Comment: 5 pages, 4 figure

Parents’ Perceptions of the Physical Health Outcomes of Young People Diagnosed with First Episode Psychosis

This study explores parents’ perceptions of their son/daughter’s physical health needs following a first episode psychosis diagnosis and commencement on antipsychotic medication. The research process was guided by grounded theory methodology and data were collected using semi-structure interviews with 16 parents. Four categories were identified. Participants described the importance, challenges and strategies for their son/daughter to maintain their physical health, and the need to improve young people’s health literacy, particularly in areas of physical health, diet and lifestyle. These findings will assist health professionals to provide parents with information to better support their son/daughter to maintain their physical health

Measurement of the Target-Normal Single-Spin Asymmetry in Quasielastic Scattering from the Reaction ³He↑(e, e\u27)

We report the first measurement of the target single-spin asymmetry, Ay, in quasielastic scattering from the inclusive reaction ³He↑(e, e\u27) on a ³He gas target polarized normal to the lepton scattering plane. Assuming time-reversal invariance, this asymmetry is strictly zero for one-photon exchange. A nonzero Ay can arise from the interference between the one-and two-photon exchange processes which is sensitive to the details of the substructure of the nucleon. An experiment recently completed at Jefferson Lab yielded asymmetries with high statistical precision at Q2 = 0.13, 0.46, and 0.97 GeV2. These measurements demonstrate, for the first time, that the 3He asymmetry is clearly nonzero and negative at the 4σ-9σ level. Using measured proton-to-3He cross-section ratios and the effective polarization approximation, neutron asymmetries of -(1-3)% were obtained. The neutron asymmetry at high Q2 is related to moments of the generalized parton distributions (GPDs). Our measured neutron asymmetry at Q2 = 0.97 GeV2 agrees well with a prediction based on two-photon exchange using a GPD model and thus provides a new, independent constraint on these distributions
