Some new nonlinear retarded sum-difference inequalities with applications

The main objective of this paper is to establish some new retarded nonlinear sum-difference inequalities with two independent variables, which provide explicit bounds on unknown functions. These inequalities given here can be used as handy tools in the study of boundary value problems in partial difference equations. © 2011 Wang et al; licensee Springer.published_or_final_versio

Lexical tone awareness in Chinese children with developmental dyslexia

This study examined the extent and nature of lexical tone deficit in Chinese developmental dyslexia. Twenty Cantonese-speaking Chinese dyslexic children (mean age 8;11) were compared to twenty average readers of the same age (CA control group, mean age 8;11), and another twenty younger average readers of the same word reading level (RL control group, mean age 7;4) on different measures of lexical tone awareness, rhyme awareness and visual-verbal paired-associate learning. Results showed that the Chinese dyslexic children performed significantly worse than the CA but not the RL control groups in nearly all the lexical tone and rhyme awareness measures. Analyses of individual performance demonstrated that over one-third of the dyslexic children showed a deficit in some aspects of tone awareness. Tone discrimination and tone production were found to correlate significantly with Chinese word reading. These findings confirm that Chinese dyslexic children show weaknesses in tone awareness.published_or_final_versio

An actuarial approach to assessing personal injury compensations in Singapore: Theory and practice

In Singapore personal injury litigations, successful claimants usually receive their compensations as a lump sum. The main advantage of a lump sum payment is that the proceedings can be concluded with a 'clean break' between the parties. The lump sum is a result of discounting the future pecuniary values into a single present-day amount, considering the time value of money and the claimant's mortality. Conventionally, lump sum awards are determined by making reference to a spread of amounts in comparable cases. However, a fairer method would be one that involves input from not only lawyers but also other experts including economists and actuaries. This study, which is carried out by an inter-professional working group, provides a set of actuarially computed tables for use in personal injury settlements in Singapore. The calculations involve a consideration of recent advancements in stochastic mortality modeling and an empirical study on the econometrics of real returns on risk-free assets in Singapore. We then present two recent personal injury cases in Singapore, aiming at helping the Singapore legal profession understand and use the economic principles with actuarial tables, and educating economists and actuaries the legal concerns and concepts in personal injury cases. © 2010 World Scientific Publishing Company.postprin

Using Actuarial Evidence in Singapore and Hong Kong: A Sequel to “Lai Wee Lian Revisited”

Following the English common law, successful claimants in personal injury and clinical negligence cases in Singapore and Hong Kong usually receive their compensations as a lump sum. The amount in respect of future expenses and loss of future earning is a result of discounting the future pecuniary values into a single present-day amount, considering inflation, the time value of money and the claimant’s mortality. Using actuarial tables based on projections of the mortality rate of the general population may be considered as an alternative method in converting the future loss of earnings and future expenses into a lump sum reflecting its present value. For this purpose, a set of actuarial tables are constructed in this article. Various options for determining the appropriate discount rate(s) are explored in the context of the statistical and economic data of Singapore and Hong Kong.published_or_final_versio

The clinical course of polymyalgia rheumatica in Chinese

Polymyalgia rheumatica (PMR) is diagnosed based on clinical features that may overlap with other rheumatic conditions like rheumatoid arthritis (RA). Furthermore, a proportion of PMR patients may subsequently evolve into RA. The aim of this study was to examine the clinical characteristics of PMR patients in a Chinese cohort compared to a Caucasian series. Patients diagnosed to have PMR during 1997-2008 were reviewed for clinical features and compared to a reported Caucasian series. Rheumatoid factor (RF) and anticyclic citrullinated peptide (CCP) antibodies were determined by immunonephelometry and enzyme-linked immunosorbent assay, respectively. Forty-four patients of southern Chinese origin were diagnosed to have PMR according to specialist opinion. Seventy-five percent of patients (n = 33) were >65 years of age at diagnosis (mean ± standard deviation, 75.8 ± 9.6 years). The commonest feature at disease onset was elevated erythrocyte sedimentation rate >40 mm/h (100% vs. 95.7%; p = 0.17) and bilateral shoulder pain or stiffness (95.5% vs. 90.8%; p = 0.31), comparable in frequency to the Caucasian cohort. However, Chinese patients had significantly longer duration of symptoms before diagnosis (p < 0.001) but less bilateral upper arm tenderness (p < 0.001) and generalized stiffness (p = 0.01). Twelve (27.3%) patients evolved into RA after a median duration of 2 months from onset of PMR. RF and anti-CCP antibodies were positive in 66.7% and 60% of these patients compared to 9.4% and 6.2%, respectively, among those who did not evolve into RA during the period observed. Chinese patients with PMR have modestly different clinical profile compared to the Caucasian counterpart. RF and anti-CCP antibodies were more likely to be present in those who subsequently developed into RA. © 2009 Clinical Rheumatology.postprin
