  • Current models of flowering with budding  developed (MODSIM 2015, MODSIM 2013 and Phenology 2012)
  • The book by Hudson & Keatley (eds) (2010) “Phenological Research: Methods for Environmental and Climate Change Analysis” (Springer) (Hudson authored 9 chapters), and an invited chapter Meta-analysis for the Encyclopaedia of Climate & Weather (2011), OUP are significant translational research bringing stat/epi thinking into climate change research. 

[III] Sleep, health and aging (Hunter Medical REsearch Institute, HMRI) (2011-current):

  • Developed new latent class joint models of sleep and survival
  • See Leigh, Hudson, Byles, Sleep Medicine 2014 and our paper in Journal of Ageing and Health 2015).
  • Developing also state-of-the-art Bayesian clustering linking survival to covariates via clusters.
  • This research was presented at 2014 Brunel University meeting in London on reliability engineering, medicine and biology (Liverani, Leigh, Hudson, 2014).
  • Our models correlate sleep problems with specific diseases and with overall improved survival in the very old.

[IV] Human Factors and  Sleep - Railway Industry scheduling - fatigue mitigation (2010 - current)

  • Funded  earlier by a CRC-railway industry grant  in collaboration with the Appleton Institute Behavioural Science, Human Factors & Safety, CqU
  • Hudson adapted artificial intellignce methods, ANNs and SOMs along with  transitional state methods  to sleep/work/domestic factors and scheduling.
  • Presented a prelim work at the 2013 Workshop on Statistical Modelling, Palermo, Sicily.
  • This work in a new book on Studies in Computational Intelligence 2016, Springer.

[V]  WHO: New methods to model global tobacco use with the WHO, Geneva

  • This research is to develop new rigorous statistical methods to model global tobacco use with the WHOis in collaboration with 
    Dr Edouard Tursan d'Espaignet, Coordinator Comprehensive Information Systems for Tobacco Control Free Initiative (TFI), (WHO, Geneva), Prof David Levy, Pacific Institute Research & Evaluation, University of Baltimore, USA,  Prof IL Hudson and Drs Frank Tuyl and Trevor Moffet (MAPS). 
  • Builds on significant impact of team’s 2015 Lancet paper; 'Global trends and projections for tobacco use, 1990-2025: an analysis of smoking indicators from the WHO Comprehensive Information Systems for Tobacco Control',
    The Lancet, 385 966-976 (
    2015). To date this paper has an altmetric score of 64.
  • Recently funded  by  2015 and 2014 Dept of Health and WHO TFI grant monies.

    [VI] Image analysis/ psychometric constructs (2003-current): 

    • Prof Hudson (Turner, Hudson, 2003 NeuroImage) tackled the question of whether personality affects depression by mapping SPECT based cerebral blood flow with respect to Prof CR Cloninger’s psychometric Temperament and Character (TCI) traits, used as a diagnostic tool for personality disorders.
    • All traits were shown to exhibit differential associations with 9 depression symptoms and distinctive patterns of functional brain activity. This provided mathematical evidence of a possible biological basis for depression (as hypothesised earlier by Cloninger).
    • Neuroanatomical correlates of individual differences in the brain with all TCI scores were also found by independent component analyses (Kang, Hudson et al., 2013).
    • This and Hudson’s GAMLSS and latent class trajectory research (2012, 2015) validates need for non-linear psychometric models (acknowledged by Prof CR Cloninger) which are also gender-specific, adding significant impetus for the creation of patient-specific drugs for depression.

    Professor Irene Hudson is a mathematical statistician working in diverse research areas of computational intelligence, drug discovery, health informatics, genomics, phenomics, bio-informatics, biostatistics and climate change modelling and phenology. Mapping and modelling of micro systems (brain voxels, molecules, wood anatomical measures) and macro systems (global incidence of disease, climate) underpins Hudson's research. 

    Hudson was appointed Head of the Biostatistics Unit, The University of Melbourne from 1983–1989.

    Irene led the first statistical research group in Australia to create a paediatric diagnostic related groups (DRGs) case-mix cost, length of stay system. To that date only adult DRG's were in place. Irene has continued since then (1982 – current), both theoretical statistical research and applied research in medical biostatistics and health informatics.

    In 1989-1993 Hudson was a Senior Statistical Consultant and Lecturer at the Mathematics and Statistics department at The University of Melbourne where she created an extensive consulting portfolio and continued bio-statistical research in cystic fibrosis and lung function processes.

    From 1997–2006 Hudson was Senior Lecturer in the Department of Mathematics and Statistics, Acting Head for  2003-4 at the University of Canterbury (UC) NZ, where, her research focus was in clinical trials, psychometrics/brain function, modelling sudden infant death with climate, medical bio-engineering, internet traffic and climate change. Psychometric  work summarised  as follows: 

    • Psychometrics and brain image analysis research that involves modelling SPECT brain image data with respect to personality (Turner, Hudson et al., 2003 NeuroImage) and depression symptoms; and wavelet modelling of agitation-sedation profiles of patients in ICU (Kang, Hudson et al., 2011, 2013  - in Discrete Wavelet Biomedical Applications, ISBN 978-953-307-654-6 ) have been Hudson’s recent areas of bio-medical applications and theory.

    © Springer Science+Business Media B.V. 2010. All rights reserved. As climate change continues to dominate the international environmental agenda, phenology - the study of the timing of recurring biological events - has received increasing research attention, leading to an emerging consensus that phenology can be viewed as an 'early warning system' for climate change impact. A multidisciplinary science involving many branches of ecology, geography and remote sensing, phenology to date has lacked a coherent methodological text. This new synthesis, including contributions from many of the world's leading phenologists, therefore fills a critical gap in the current biological literature. Providing critiques of current methods, as well as detailing novel and emerging methodologies, the book, with its extensive suite of references, provides readers with an understanding of both the theoretical basis and the potential applications required to adopt and adapt new analytical and design methods. An invaluable source book for researchers and students in ecology and climate change science, the book also provides a useful reference for practitioners in a range of sectors, including human health, fisheries, forestry, agriculture and natural resource management.

    © Springer Science+Business Media B.V. 2010. All rights reserved. The research field of plant phenology, which often involves the monitoring of several to hundreds of species of different life forms and/or different vegetation types, has increased exponentially over the last three decades. This has occurred in general, without consideration of the comparability of data and patterns across areas, and its influence on the interpretation of resultant patterns. In this chapter we address the influence of sampling method, sample size and the frequency of observations on the analysis of tropical tree phenologytropical tree phenology. Our approach is to compare the results of direct observations on transects with those obtained from litter traps. Transects and litter traps are the two most common methods used to sample and monitor plant phenology. Data from 3 locations were used to simulate different sample sizes and frequencies, and results were then compared with the original data. We conclude that sample size influences the patterns observed and there is a clear trade off between sample size and the frequency of observations. We show that direct observations were more accurate in defining both the beginning and the peak of phenological phases, and there was a significant difference between the peaks and seasonal patterns detected by both sampling methods. For tropical tree forest applications we recommend a minimum sample size of 15 trees and that a fortnightly frequency of observation be used especially if the sample size is small. We advocate the combination of presence/absence data and a quantification method to estimate plant phenology, a careful application of indices and a cautious generalization of pattern.

    © Springer Science+Business Media B.V. 2010. All rights reserved. Climate change is one of the greatest challenges to sustainable development. Results from many individual studies show significant variation in response to climate change and human activities. Given the scope and variability of these trends, global patterns may be much more important than individual studies in assessing the effects of global change. There is a need to synthesize quantitatively, existing results on ecosystems and their responses to global change, in order to reach a general consensus or summarize the differences. Meta-analysis provides such a quantitative synthetic method, in that it statistically integrates results from individual studies to find common trends and differences: so called fingerprints of change. Only a small number of studies to date have performed a formal statistical meta-analysis of species' responses or have synthesized independent studies to reveal emergent and globally coherent patterns of ecological changes in physical and in biological systems in the phenology and distribution of plants and animals. There are very few reports available on the use of meta-analysis to examine global climate change in Australia. The unequivocal conclusion across the global syntheses, to date, is that twentieth-century anthropogenic global warming has already impacted on the Earth's biota. This chapter reviews the general methodology of meta-analysis, assesses its advantages and disadvantages, synthesizes its use in global climate change phenology and discusses future directions and proposes new statistical methods, as yet not applied to phenological research, and only recently applied, only in part, in the health-climate epidemiological literature.

    © Springer Science+Business Media B.V. 2010. All rights reserved. Phenology is the study of recurring biological events and its relationship to climate. Circular statistics is an area of statistics not very much used by ecologists nor by other researchers from the biological sciences, and indeed not much visited, till recently in statistical science. Nevertheless, the connection between the evaluation of temporal, recurring events and the analysis of directional data have converged in several papers, and show circular statistics to be an outstanding tool by which to better understand plant phenology. The aim of this chapter is to assess applications for circular statistics in plant phenology and its potential for phenological data analysis in general. We do not discuss the mathematics of circular statistics, but discuss its actual and potential applications to plant phenology. We provide several examples at various levels of application: from generating circular phenological variables to the actual testing of hypotheses, say, for the existence of certain a priori seasonal patterns. Circular statistics has particular value and application when flowering onset (or fruiting) occurs almost continuously in an annual cycle and importantly in southern climates, where flowering time may not have a logical starting point, such as mid-winter dormancy. We conclude circular statistics applies well to phenological research where we want to test for relationships between flowering time and other phenological traits (e.g. shoot growth), or with functional traits such as plant height. It also allows us to group species into annual, supra-annual, irregular and continuous reproducers; to study seasonality in reproduction and growth; and to assess synchronization of species.

    © Springer Science+Business Media B.V. 2010. All rights reserved. The multivariate relationship between the probability of flowering, in relation to two discrete states of rainfall and of temperature (high/low), is investigated via a mixture transition distribution (MTD) analysis, which allows for a different transition matrix for each lag (up to 12 months backwards in time) to present flowering via a so-called MTDg analysis. The conventional mixture transition distribution (MTD) model considers the effect of each lag to the present independently, and uses equal transition matrices among different lags. Flowering data consisted of monthly flowering records of E. leucoxylon, E. microcarpa, E. polyanthemos and E. tricarpa (1940 and 1970). We extend the MTDg model to allow for interactions (between rain and temperature) to account for changes in the transition matrices amongst the differing lags. The MTDg model with interactions shows that the flowering of E. leucoxylon and E. tricarpa behave similarly with temperature (both flower at low temperature) and have a positive relationship with flowering intensity 11 months ago. Eucalyptus microcarpa behaves differently, in that it flowers at high temperature. MTDg analysis also found a highly significant interaction between mean temperature and rainfall for E. polyanthemos, in that E. polyanthemos does not tend to flower during the winter time (when it is cold and wet). Rainfall has a direct positive impact only on E. tricarpa. These four species are influenced by temperature (and to a lesser extent rainfall) and as a consequence their flowering phenology will possibly change in response to climate change.

    © 2017 Taylor & Francis Group, LLC. In this article, we investigate the potential usefulness of the three-parameter transmuted generalized exponential distribution for analyzing lifetime data. We compare it with various generalizations of the two-parameter exponential distribution using maximum likelihood estimation. Some mathematical properties of the new extended model including expressions for the quantile and moments are investigated. We propose a location-scale regression model, based on the log-transmuted generalized exponential distribution. Two applications with real data are given to illustrate the proposed family of lifetime distributions.

    This paper introduces the transmuted new generalized inverse Weibull distribution by using the quadratic rank transmutation map (QRTM) scheme studied by Shaw et al. (2007). The proposed model contains twenty three lifetime distributions as special sub-models. Some mathematical properties of the new distribution are formulated, such as quantile function, Rényi entropy, mean deviations, moments, moment generating function and order statistics. The method of maximum likelihood is used for estimating the model parameters. We illustrate the flexibility and potential usefulness of the new distribution by means of two real data sets.

    © 2015 European Sleep Research Society. The aim of this study is to identify patterns of sleep difficulty in older women, to investigate whether sleep difficulty is an indicator for poorer survival, and to determine whether sleep difficulty modifies the association between disease and death. Data were from the Australian Longitudinal Study on Women's Health, a 15-year longitudinal cohort study, with 10¿721 women aged 70-75¿years at baseline. Repeated-measures latent class analysis identified four classes of persistent sleep difficulty: troubled sleepers (N¿=¿2429, 22.7%); early wakers (N¿=¿3083, 28.8%); trouble falling asleep (N¿=¿1767, 16.5%); and untroubled sleepers (N¿=¿3442, 32.1%). Sleep difficulty was an indicator for mortality. Compared with untroubled sleepers, hazard ratios and 95% confidence intervals for troubled sleepers, early wakers, and troubled falling asleep were 1.12 (1.03, 1.23), 0.81 (0.75, 0.91) and 0.89 (0.79, 1.00), respectively. Sleep difficulty may modify the prognosis of women with chronic diseases. Hazard ratios (and 95% confidence intervals) for having three or more diseases (compared with 0 diseases) were enhanced for untroubled sleepers, early wakers and trouble falling asleep [hazard ratio¿=¿1.86 (1.55, 2.22), 1.91 (1.56, 2.35) and 1.98 (1.47, 2.66), respectively], and reduced for troubled sleepers [hazard ratio¿=¿1.57 (1.24, 1.98)] . Sleep difficulty in older women is more complex than the presence or absence of sleep difficulty, and should be considered when assessing the risk of death associated with disease.

    © 2015 World Health Organization. Published by Elsevie r Ltd/Inc/BV. All rights reserved. Background Countries have agreed on reduction targets for tobacco smoking stipulated in the WHO global monitoring framework, for achievement by 2025. In an analysis of data for tobacco smoking prevalence from nationally representative survey data, we aimed to provide comprehensive estimates of recent trends in tobacco smoking, projections for future tobacco smoking, and country-level estimates of probabilities of achieving tobacco smoking targets. Methods We used a Bayesian hierarchical meta-regression modelling approach using data from the WHO Comprehensive Information Systems for Tobacco Control to assess trends from 1990 to 2010 and made projections up to 2025 for current tobacco smoking, daily tobacco smoking, current cigarette smoking, and daily cigarette smoking for 173 countries for men and 178 countries for women. Modelling was implemented in Python with DisMod-MR and PyMC. We estimated trends in country-specific prevalence of tobacco use, projections for future tobacco use, and probabilities for decreased tobacco use, increased tobacco use, and achievement of targets for tobacco control from posterior distributions. Findings During the most recent decade (2000-10), the prevalence of tobacco smoking in men fell in 125 (72%) countries, and in women fell in 156 (88%) countries. If these trends continue, only 37 (21%) countries are on track to achieve their targets for men and 88 (49%) are on track for women, and there would be an estimated 1·1 billion current tobacco smokers (95% credible interval 700 million to 1·6 billion) in 2025. Rapid increases are predicted in Africa for men and in the eastern Mediterranean for both men and women, suggesting the need for enhanced measures for tobacco control in these regions. Interpretation Our findings show that striking between-country disparities in tobacco use would persist in 2025, with many countries not on track to achieve tobacco control targets and several low-income and middle-income countries at risk of worsening tobacco epidemics if these trends remain unchanged. Immediate, effective, and sustained action is necessary to attain and maintain desirable trajectories for tobacco control and achieve global convergence towards elimination of tobacco use.

    There is substantial evidence of climate-related shifts to the timing of avian migration. Although spring arrival has generally advanced, variable species responses and geographical biases in data collection make it difficult to generalise patterns. We advance previous studies by using novel multivariate statistical techniques to explore complex relationships between phenological trends, climate indices and species traits. Using 145 datasets for 52 bird species, we assess trends in first arrival date (FAD), last departure date (LDD) and timing of peak abundance at multiple Australian locations. Strong seasonal patterns were found, i.e. spring phenological events were more likely to significantly advance, while significant advances and delays occurred in other seasons. However, across all significant trends, the magnitude of delays exceeded that of advances, particularly for FAD (+22.3 and -9.6 days/decade, respectively). Geographic variations were found, with greater advances in FAD and LDD, in south-eastern Australia than in the north and west. We identified four species clusters that differed with respect to species traits and climate drivers. Species within bird clusters responded in similar ways to local climate variables, particularly the number of raindays and rainfall. The strength of phenological trends was more strongly related to local climate variables than to broad-scale drivers (Southern Oscillation Index), highlighting the importance of precipitation as a driver of movement in Australian birds. © 2013 ISB.

    Since its inception in the 1950s the odds ratio has become one of the most simple and popular measures available for analysing the association between two dichotomous variables. Since the direction and magnitude of the association can be captured in such a simple measure, its impact has been felt throughout much of scientific research, in particular in epidemiology and clinical trials. Despite this, its applicability for analysing aggregate data has rarely been considered. In this paper we shall express a new measure of association (the aggregate association index, or AAI), in terms of the classic odds ratio. The advantage of doing so is that we are able to explore the use of the odds ratio in a context for which it was not originally intended, and that is for the analysis of a 2×2 table where only the aggregate data is known. © 2013 Published by Elsevier B.V.

    A statistically significant shift in the date of flowering commencement in some Australian plants is discussed. The annual average of the mean and maximum daily temperature were found to have increased by 0.83°C and 1.08°C during the period from 1965 to 2002. The climate change is found to have a significant impact on the reproductive behavior of plant species in the area of south-eastern Australia. It is indicated that there is a change in local temperature over time and that the flowering phenology of some species has changed.

    Phenological observations of eucalypts (Myrtaceae) were undertaken in four Australian states (New South Wales, Queensland, Victoria, and Western Australia) from the late 1920s until the early 1980s, by the respective State Forest Commissions. Unfortunately, few records have survived. For Victoria, surviving records encompass 42 forest districts, covering from less than 2 years to 42 years, and approximately 50 species. This paper concentrates on the flowering of four competing species (Eucalyptus leucoxylon, E. microcarpa, E. polyanthemos, and E. tricarpa) over 23 years (1940-62) from Maryborough, Victoria, recorded on a monthly basis by one observer over the period. This study represents one of the first attempts to utilize Australian phenological data to detect responses to climate change. There were no significant trends (P = 0.05) over time in the mean flowering commencement date. Forward stepwise regression found a significant relationship between temperature and flowering commencement in two species (E. leucoxylon: R 2 = 0.42, P < 0.01; E. polyanthemos: R 2 = 0.47, P = 0.02). Rainfall also had a significant influence on flowering commencement in E. tricarpa (R 2 = 0.60, P < 0.01), E. leucoxylon (R 2 = 0.43, P = 0.02) and E. polyanthemos (R 2 = 0.24, P < 0.01). The combination of temperature and rainfall (with temperature exerting the greatest influence), however, was significant for all species and had the most explanatory power (ranging from R 2 = 0.74 to 0.85, P < 0.01). Overall, in response to predicted increases in temperature and summer rainfall, E. leucoxylon and E. tricarpa would commence flowering later. In E. polyanthemos and E. microcarpa, increased temperature and rainfall will result in an earlier onset of flowering. © 2002 Royal Meteorological Society.

    Well-formed E. nitens and E. globulus tree were each destructively sampled with discs cut at nine percentage heights. Intense within-ring sampling and measurement of fibers provided whole tree maps of variation of fiber dimensions. Whole tree and area-weighted disc values were successfully calculated, with and without adjustment for earlywood (EW) and latewood (LW) volumes or areas (EML Adj.).

    The potential of plantation-grown Eucalyptus cladocalyx F Muell., E. globulus Labill. subsp. globulus, Corymbia maculata (Hook.) K. Hill and L. Johnson and E. sideroxylon Cunn. ex Woolls subsp. sideroxylon as a resource for high quality sawn products in the winter, medium rainfall zones (580¿750 mm) of the southern Murray-Darling Basin were investigated in this study. Six plantations ranging in age from 15 to 40 years from within the region were selected for harvest. Sawing involved back-sawing strategies which have been shown to maximise the output of high quality products from small diameter eucalypts. To evaluate out-turns of appearance products and to assess the effect of tree growth characteristics (primarily branches, knots, kino and other characteristics) on sawn product appearance, green product quality and recovery were assessed using CSIRO appearance grading criteria. Evaluation of products was conducted in specific zones of the inner heartwood (within 50 mm of the pith) and outer heartwood (greater than 50 mm from the pith) and on a whole log basis. Based on green product appearance, good recoveries of high quality products were obtained for 36 to 40-year-old E. cladocalyx, 40-year-old C. maculata and 40-year-old E. sideroxylon. Alternatively, the potential for 15-year-old E. globulus and 26-year-old E. sideroxylon suggested that the potential would not be as good without some reduction in significant defects, particularly knots and kino. Knots were a major defect in sawn products from all plantations. Evaluation of boards from inner heartwood and outer heartwood zones showed that with the removal of knots an increase in recovery of products of select grade and better would be possible in the outer heartwood in all species. This indicates a potential improvement in product quality had mechanical pruning been employed. However, improvement in quality in C. maculata and E. cladocalyx would be modest after pruning because of good natural branch shedding characteristics in these species. © 1999 Taylor & Francis Group, LLC.

    Background: The effect of diet change in 38 bottle-fed and 77 breast-fed "colicky" infants, referred from community-based pediatric facilities was studied over a 1-week period in a double-blind (within each feeding mode), randomized, placebo-controlled trial. Methods: Bottle-fed infants were assigned to either casein hydrolysate or cow's milk formula. All mothers of breast-fed infants were started on an artificial color-free, preservative-free, additive-free diet and also randomized to an active low allergen diet (milk-, egg-, wheat-, nut-free) or a control diet. Results: The response to diet was assessed on day 1 and day 8 with the use of a previously validated infant distress chart on which parents recorded distress levels. If successful outcome was defined as a reduction in distress of 25% or more, after adjusting for age and feeding mode, infants on active diet had a significantly higher rate of improvement than those on the control diet (odds ratio, 2.32; 95% confidence interval, 1.07-5.0; p = 0.03). Analysis of the day 8 to day 1 distress ratio, again adjusted for age and feeding mode, showed that infants on the active diet had distress reduced by 39% (95% confidence interval, 26-50) compared with 16% (95% confidence interval, 0-30) for those on the control diet (p = 0.012). Conclusion: The results suggest a period of dietary modification with a low allergen diet and appropriate nutritional support should be considered in healthy infants with colic.

    The value of a 24-hour distress diary, previously validated against a voice-activated audiotape record, was investigated in 30 infants with colic and 30 control infants. The infants with colic had significantly more distress behavior (300.0 minutes vs 102.5 minutes; p < 0.001), although overlap of duration of distress was noted. On the basis of a clinical definition of colic-total distress lasting 180 minutes in a 24-hour period-the diary had a sensitivity of 77% and a specificity of 87%. The sensitivity of the chart was confirmed in a separate study of another 90 infants with colic. © 1992 Mosby-Year Book, Inc.

    This study relates the timing and incidence of orchidopexy to possible ascent of the testis. During 1985, 341 patients underwent surgery for undescended testes at the Royal Children's Hospital, Melbourne. In 85 (25%), surgery was performed before 2 years of age. The number of children managed surgically over the age of 2 years is high (75%) despite our surgical policy to perform orchidopexy at 2 years of age. Statistical analysis shows a bimodal distribution for age at the time of surgery for undescended testis, with 16% of the orchidopexy population in the older age group. It also demonstrates that the overall orchidopexy rate of 2.6% is three times the expected incidence of undescended testes at 1 year of age. Possible explanations for these observations include: (1) the diagnosis and referral of undescended testis is being made late; (2) surgery is being performed on retractile testes; or (3) some later presenting undescended testes are acquired, the so-called ascending testes. © 1990 Springer-Verlag.

    In a study of cows' milk allergy (CMA) in infancy, 135 consecutive challenges were performed on children with a good clinical history of the disorder. Of these, only half of the patients were shown to have the disease. Highly atopic patients responded rapidly to small volumes of milk with acute urticaria, wheezing, stridor and eczema, whereas patients who were relatively non-atopic developed symptoms of eczema, bronchitis and wheezing over several hours or days. In a statistical evaluation of the diagnostic value of skin tests and RAST it was shown for the extracts used in this investigation, and for the population studied, all patients with SPT =4 had CMA. The results highlight the potential diagnostic value of SPT in the identification of children with some forms of CMA if standardized cows' milk allergen extracts can be prepared.

    Lung mechanics and partial forced expiratory flows were measured serially in seven normal infants during the first year of life. Lung mechanics were measured by the end inspiratory occlusion technique and partial forced expiratory flows by the rapid chest compression method. Thoracic gas volume, compliance, and partial forced expiratory flows measured at functional residual capacity progressively increased with age and correlated with height cubed. Respiratory system resistance progressively fell whereas volume-corrected flows remained fairly constant over the study period. These findings provide longitudinal lung function data and support the concept of isotropic lung growth. Pediatr Pulmonol 1987; 3; 3¿7. Copyright © 1987 Wiley-Liss, Inc., A Wiley Company

    Abstract The many conceptual and methodological difficulties involved in evaluating depression rating scales for children arc discussed. A clinical validation of the Depression Self Rating Scale for Children (DSRSC) is described. The instrument is easy to use and has a predictive value comparable with that of a psychiatric global rating of depressed appearance and history of depression obtained at interview. There was confirmation that the: DSRSC can tap an internal dimension of depression and that children are able lo evaluate their feeling stales. An examination of misclassified children pointed to diagnostic overlap and some unreliability of diagnosis by clinicians. Copyright © 1987, Wiley Blackwell. All rights reserved

    A group of 323 subjects who had wheezed in childhood and 48 control subjects of the same age were studied prospectively from 7 to 28 years of age. A classification system based on wheezing frequency was found to correlate well with clinical and spirometric features of airway obstruction. The amount of wheezing in early adolescence seemed to be a guide for severity in later life with 73%-of those with few symptoms at 14 continuing to have little or no asthma at 28 years. Similarly 68% of those with frequent wheezing at 14 still suffered from recurrent asthma at 28 years. Most subjects with frequent wheezing at 21 continued to have comparable asthma at 28 years. Of those with infrequent wheezing at 21, 44% had worsened at 28 years. Women fared better than men between 21 and 28 with 19% having worse symptoms compared with 28% of men. Treatment at all ages was generally inadequate. The number of smokers among those with asthma was of concern. © 1987, British Medical Journal Publishing Group. All rights reserved.

    A preliminary report of a method for assessing the quality of movement in children with cerebral palsy, using an accelerometer, is presented. Able-bodied and disabled children performed a simple task, and there were marked differences between the two groups. Whilst the technique requires further development, it is hoped that accelerometry may eventually provide an objective tool to enable rigorous testing of various therapeutic procedures in cerebral palsy Copyright © 1987, Wiley Blackwell.

    The effect of nebulized ipratropium bromide in 14 infants (mean age:20 weeks, range:4¿41) with acute respiratory syncytial virus bronchiolitis was examined. A modified rapid chest compression technique was used to obtain partial expiratory flow-volume curves and maximum flow at functional residual capacity. Passive respiratory mechanics were assessed by brief occlusion at end inspiration. Thoracic gas volume was measured in a body plethysmograph. No significant difference was found in forced and passive respiratory mechanics pre- and post-ipratropium bromide. No subgroups could be identified. These results do not support the use of ipratropium bromide in acute viral bronchiolitis. Copyright © 1987, Wiley Blackwell. All rights reserved

    A review was conducted of 234 consecutive patients with hypertrophic pyloric stenosis (HPS) proven at operation. The relationship of age, sex, the duration of symptoms and the clinical degree of dehydration to the severity of metabolic derangement as reflected by alterations in serum electrolytes and acid-base status, was analysed statistically. The length of history and the degree of dehydration was found to have predictive value in identifying those likely to have major metabolic disturbances. Where severe vomiting has persisted for more than 1 week, major derangements of the biochemical parameters should be anticipated; and where clinical assessment of dehydration is estimated as being greater than 5%, there is almost always some major biochemical abnormality present. Nevertheless, variation in individual cases necessitates that all patients with suspected HPS should have serum electrolytes and acid-base estimations performed. Copyright © 1986, Wiley Blackwell.

    Adenoviruses are well known causes of respiratory illness in children. Long term sequelae reported with types 3, 7, and 21 include bronchiolitis obliterans, bronchiectasis, and the hyperlucent lung or McLeod syndrome. Twenty children admitted to hospital with adenovirus type 7 pneumonia between 1960 and 1978 were studied and compared with 20 controls admitted during the same period with adenovirus type 7 upper respiratory tract infections. Sixty five per cent of the pneumonia group had developed evidence of airways obstruction compared with 10% of controls. Young age at the time of pneumonia and a 'measles-like' illness before its onset increase the chance of developing long term pulmonary function abnormalities. Sex and family history of smoking or atopy do not influence outcome.

    © 2017 Author(s). Nested Sampling is a powerful algorithm for fitting models to data in the Bayesian setting, introduced by Skilling [1]. The nested sampling algorithm proceeds by carrying out a series of compressive steps, involving successively nested iso-likelihood boundaries, starting with the full prior distribution of the problem parameters. The "central problem" of nested sampling is to draw at each step a sample from the prior distribution whose likelihood is greater than the current likelihood threshold, i.e., a sample falling inside the current likelihood-restricted region. For both flat and informative priors this ultimately requires uniform sampling restricted to the likelihood-restricted region. We present two new methods of carrying out this sampling step, and illustrate their use with the lighthouse problem [2] , a bivariate likelihood used by Gregory [3] and a trivariate Gaussian mixture likelihood. All the algorithm development and testing reported here has been done with Mathematica® [4] .

    The axes of variation in fiber morphology of Eucalyptus nitens were compared with Eucalyptus globulus as a function of sampling height, and within ring EW and LW. In E. nitens, an exact EW to LW profile was observed and sustained longitudinally up to 80% AH in all rings. The longitudinal variation in E. nitens was less consistent between rings than in E. globulus. The repeating sequence of EW, MW and LW partitioning confirmed the highly significant EW to LW differentiation of fibers in E. nitens, not shown in E. globulus.

    This paper presents an ABR control scheme (ABR 2 - DP) which maximises the utilisation of information available about the network traffic. Firstly, it takes into account the long-range dependence of the self-similar background network traffic, and utilises it for more accurate multi-step predictions of the explicit rate (ER). Secondly, prediction errors for connections with greater network delay are compensated for in the ER calculations for connections with smaller delay. Hence, the available bandwidth is distributed both in temporal and spatial dimensions. The scheme allows a reduction in buffer requirements and queueing delay. Performance results are presented and compared with a previously proposed scheme which uses digital filtering. © 1999 IEEE.
