Recent funding (2007-2015) as CI:   on a 2015 National Health & Medical Research Council (NHMRC) Development Grant on stroke  health; a 2014 Department of Health/Ageing grant to assess global tobacco use prevalence (with the WHO Tobacco Free Initiative Comprehensive Information Systems); a CRC Rail Innovation grant with the Appleton Institute for Behavioural Science, Human Factors and Safety, CqU (on sleep scheduling, work/health & safety), an ARC DP grant with Adelaide University (drug discovery), a SA Premier Science Research Fund (on phenomics),  a 2011 Australian Mathematics Society Teaching & Learning  network grant (with QUT, CqU, UniSA, Adelaide Uni); and  recently with NSW Crime Statistics (Hudson with Dr Joanne Thandrayan and Prof D Weatherburn 2014-2015).

Research impact:

[I] Image analysis/ psychometric constructs (2003-current): Prof Hudson (Turner, Hudson, 2003 NeuroImage) tackled the question of whether personality affects depression by mapping 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 (2013-2014) validates need for non-linear psychometric models (acknowledged by Cloninger) which are  also gender-specific, adding significant impetus for the creation of patient-specific drugs for depression.

[II] Drug discovery/chemo-informatics (2007-current): Prof Hudson leads a team to create new indicators of molecular ligand binding for drug discovery, with a focus on testing calpain inhibitors for cataract treatment (with Cambridge University and Adelaide University).  Hudson has developed new generic druggability rules for the drug industry (with UCSF, USA and UniAdelaide). Both research areas are funded by an ARC DP 2007-2010 (CIs Abell, Hudson, Grubbs), by a UoN PostDoc and PhD award (2011-2014). Hudson presented this chemo-space visualization/ clustering research at ASC 2014, ASEARC 2014, MODSIM 2013, and ANZIAM 2013.

[III] Sleep, health and aging (HMRI) (2011-current): Developed new latent class joint models of sleep and survival (Leigh, Hudson, Byles, Sleep Medicine 2014) and 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] Climate Change: Prof Hudson has an international reputation in climate change methods. Hudson has developed new statistical techniques for climate research - placing the southern hemisphere on the global climate change map. Hudson’s Australasian climate research was recently reported at the 2014 IPCC.  The book by Hudson & Keatley (eds) (2010) “Phenological Research: Methods for Environmental and Climate Change Analysis” (Springer) (Hudson authored 9 chapters, cited >130 times), 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. Hudson’s Using Self-Organising Maps (SOMs) to assess synchronies”, Intl Journal Biometeorology (2011) is at the top of the top 20 articles in SOMs. Recently Hudson adapted SOMs to sleep/scheduling, CRC-funded research with the Appleton Institute Behavioural Science, Human Factors & Safety, CqU – this work was presented at 2013 Workshop on Statistical Modelling, Italy.

Innovation: [1] Agitation-sedation   (A-S) monitoring in ICU: www.rgms.nhmrc.gov.au/niku/app?action=odf.gm_cv_translation_toProperties&amp;odf_code=gm_cv_translation_to&amp;grandparent_odf_view&amp;odf_concrete_parent_object_code=gm_profile_cv&amp;parent_odf_view=gm_profile_cvCreate.subObjList.gm_cv_translation_to&amp;odf_cncrt_parent_id=5593381&amp;ui.page.space=odf.gm_profile_cvList&amp;odf_pk=6723208" title="Agitation Monitoring Technology: A breakthrough technology enabling improved healthcare for the critically ill. Agitation-sedation (A-S) cycling in critically ill ICU patients, characterized by oscillations between states of agitation and over-sedation,">A breakthrough technology for improved healthcare in the critically ill. From 2000-2006 Prof Hudson was part of a team in Mechanical Engineering (Prof G Chase), Canterbury University and Christchurch School of Medicine which created a model capturing the essential dynamics of the A-S system and validated the model statistically. Hudson’s current research on A-S pharmacodynamics (2006-2014) challenges the practice of sedating with continuous infusions and advances knowledge of A-S control. Hudson proved that wavelets provide a new diagnostic tool to assess A-S via control metrics/visualization. Hudson’s 2011 chapter, http://www.intechopen.com/books/discrete-wavelet-transforms-biomedical-applications/wavelet-signatures-and-diagnostics-for-the-assessment-of-icu-agitation-sedation-protocols"><strong><em>Wavelet Signatures Diagnostics for the Assessment of ICU Agitation-Sedation Protocols and 2013 chapter Density Estimation & Wavelet Thresholding via Bayesian Methods have been downloaded > 2,000 times. This wavelets research to feature in a 2015 Springer book “Signal processing & Spectral Analysis”.

[2] Paediatric DRGs (1988-1993): Hudson led a team, as Head of the UniMelb Biostatistics Unit that created the first paediatric DRGs for hospital case mix in Australia. Paediatric DRGs were then used as policy/practice for length of stay (funded by Commonwealth Health Dept., CIs Prof PD Phelan, IL Hudson and B Catchlove, 1988-90).

[3] Wood informatics: Hudson led the first group world-wide that identified “mid-wood” micro-structure regions in Eucalypt tree rings (as Sub Program 1.2 Leader, CRC-HFPS, 1993-97, UniMelb). The research proved that simple wood fibre morphological models were inadequate to model whole tree variation. This led to a coordinated change in wood quality sampling protocols in Australasia (Downes, Hudson et al., 1997, CSIRO Pub), and was crucial to calibration of CSIRO’s SilviScan2, an international X-ray device for rapid wood quality image testing. This work forged CSIRO’s later within-ring paleoclimatic change research (2007- ).

 International/ Peer Recognition: • Hudson is a major collaborator with the BOM and CSIRO’s Centre for Australian Weather and Climate - developing a phenological index for Australia (2013-). This research to be reported to the UN Convention on Biological Diversity. • Hudson was a CI with Profs J C Rodger (SELS, UoN), Kerrie Mengersen, T Pettitt (QUT), R Pech (LandcareNZ) on a CRC Safeguarding Bio-Diversity bid “Strategic Reintroductions and Translocations” - short-listed in 2013 but unsuccessful. Based on CRC interviews our bid reformulated into a 2014 grant bid for the NSW Dept. Environment & Heritage, via Fauna Research Alliance Inc. (J Rodger, IL Hudson et al.). 

• Hudson invited speaker at 2014 EU/China conf. on singular spectrum analysis (SSA) and image analysis - with a Springer commission for an SSA book (Hudson & Hassani).• Hudson presented at 38 inter/national workshops. Stream leader in health informatics for international biennial MODSIM conference (2007-2015), MODSIM 2013 and MODSIM 2015.

Research Expertise
Professor Irene Hudson is also a mathematical statistician working in diverse research areas of 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.

Teaching Expertise
Hudson was appointed Head of the Biostatistics Unit, Melbourne University 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 statistical research in cystic fibrosis and lung function. From 1997–2006 Hudson was Senior Lecturer in the Department of Mathematics and Statistics, at the University of Canterbury (UC) NZ, where, in clinical trials, psychometrics/brain function, modelling sudden infant death with climate, medical bio-engineering, internet traffic and climate change were the main areas of her research and published papers.

Collaborations
Hudson is an active research collaborator and member of the Priority Research Centre for Gender, Health & Ageing and member of the Priority Research Centre, CARMA at the University of Newcastle. Hudson joined The University of South Australia in 2006, as Director of the Statistical Consulting and Research Services and Academic Leader of Statistics. At Uni SA she forged research collaborations with environmental scientists (ARC Prof A Lowe, and Prof Chris Daniels, Barbara Hardy Research Centre) and with the Uni SA Centre for Sleep Research, with whom she gained a CRC Rail Innovation grant 2010-2012 to model fatigue in railway drivers. At Uni SA she was an active member of the Uni SA Phenomics & Bioinformatics Research Centre and the Centre of Industrial and Applied mathematics. Hudson also took up a research only post as Sub-Program Leader of the CRC Hardwood Fibre and Paper Science, University of Melbourne from 1993–1997, where after previous years in health, biostatistics research and consulting she found her inspiration for wood informatics and phenology research, which she still has an interest in to this day. This appointment meant working closely with the pulp and paper industry, with Forest Products (CSIRO) and APPITA at Monash University; and with NZ FRI (New Zealand Forest Research Institute). The work at the CRC resulted in a major rewrite on forest sampling and assisted the development of wood quality devices and protocols. PREFERABLE EMAIL CONTACT: irenelena.hudson@gmail.com

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.

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: R2 = 0.42, P < 0.01; E. polyanthemos: R2 = 0.47, P = 0.02). Rainfall also had a significant influence on flowering commencement in E. tricarpa (R2 = 0.60, P < 0.01), E. leucoxylon (R2 = 0.43, P = 0.02) and E. polyanthemos (R2 = 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 R2 = 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.

The potential of plantation-grown Eucalyptus cladocalyx F. Muell., E. globulus Labill. subsp. globulus, Corymbia maculata (Hook.) K. Hill & 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.

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.

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 funcitonal 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.

This paper presents an ABR control scheme (ABR2 - 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.
