Breast screening in NSW, Australia: predictors of non-attendance and irregular attendance
No full textBreastScreen Australia provides free mammography services to women in the target age group of 50 to 69 years. The program uses a variety of measures to recruit women to the service and, subsequently, encourage them to screen at two year intervals. One of the stated aims of the program is to provide equitable access to all women in the target age group. This paper analyses the extent to which systematic variation can be observed amongst women in terms of their screening behaviour, focusing on those who have never screened or are irregular screeners. Data on self reported utilisation of breast screening services was obtained from the 2002/04 NSW Health Surveys. A multinomial logit (MNL) model was used to examine the role of socioeconomic status, cultural background, education and region of residence on breast screening behaviour. The results show that lower income is associated with a woman never screening or screening irregularly. Region of residence is an important predictor of screening behaviour, although the degree of remoteness was not influential in determining participation. A higher number of hours worked was associated with women being more likely to screen irregularly. These results provide evidence of persistent and systematic variation in screening uptake and regular participation. The results also point towards targeted recruitment and retainment strategies that may provide the greatest potential benefits.breast screening, mammography, NSW, Australia
Caffeine: a cup of care? An exploration of the relation between caffeine consumption and behavioral symptons in persons with dementia
No full textAs the number of patients suffering from dementia is still growing, most of the patients display behavioral symptoms at some time during the disease and these behavioral symptoms lower the quality of life and increase the burden of caregivers, adequate management of these symptoms is warranted. However, the etiology and management of behavioral symptoms is complex, resulting in (mis)use of pharmacological interventions: a cure which is often worse than the disease. In healthy adults, caffeine is known to influence behavior. Four different studies were conducted to see if caffeine is an easy to adjust cause or a pragmatic intervention for behavioral symptoms in patients with dementia. Based on these studies, we conclude caffeine can influence behavior in persons with dementia, but most likely not in all persons, not in all situations and not all of the time; but it can have an influence. In clinical practice it is advisable to consider caffeine as a possible moderator in the clinical assessment of behavioral symptoms in persons with dementia. </p
Structural features and properties of soluble products derived from Eucalyptus globulus hemicelluloses
No full textEucalyptus globulus wood samples were subjected to double hydrothermal processing to remove extractives in the first stage, and to cause the selective solubilisation of 4-O-methylglucuronoxylan in the second stage. The hemicellulose-derived products present in the liquors from the second hydrothermal stage (substituted xylooligosaccharides, denoted XOS) were refined by treatments with membranes and ion exchange. The purified XOS product was assayed for composition and characterised by HPLC-RI, HPAEC-PAD, HPSEC, MALDI-TOF-MS and NMR techniques. The results suggested the presence of neutral and acidic XOS with a degree of acetylation of about 0.6. The fermentability of the refined XOS product by faecal inocula was assessed by measuring both substrate consumption and formation of short-chain fatty acids
Production, Refining, Structural Characterization and Fermentability of Rice Husk Xylooligosaccharides
No full textOligosaccharides produced by hydrothermal processing of rice husks (xylooligosaccharides and glucooligosaccharides) were refined by membrane processing (operating in diafiltration and concentration modes), subjected to xylanase treatment to reduce the average molar mass, and subjected to further purification by ultrafiltration (operating in concentration mode) and ion exchange. The purified products were assayed for composition, molar mass distribution and structural characterization by HPLC, HPAEC-PAD, HPSEC, MALDI-TOF-MS and NMR (1H and 13C). The fermentability of the purified product by fecal inocula was assessed on the basis of the time courses of pH and oligosaccharide concentrations. Succinate, lactate, formiate, acetate, propionate and butyrate were the major products resulting from fermentation experiments
On Supervised Human Activity Analysis for Structured Environments
No full textWe consider the problem of developing an automated visual solution for detecting human activities within industrial environments. This has been performed using an overhead view. This view was chosen over more conventional oblique views as it does not suffer from occlusion, but still retains powerful cues about the activity of individuals. A simple blob tracker has been used to track the most significant moving parts i.e. human beings. The output of the tracking stage was manually labelled into 4 distinct categories: walking; carrying; handling and standing still which are taken together from the basic building blocks of a higher work flow description. These were used to train a decision tree using one subset of the data. A separate training set is used to learn the patterns in the activity sequences by Hidden Markov Models (HMM). On independent testing, the HMM models are applied to analyse and modify the sequence of activities predicted by the decision tree

Domain-specific Image Geocoding: A Case Study On Virginia Tech Building Photos
No full textThe use of map-based browser services is of great relevance in numerous digital libraries. The implementation of such services, however, demands the use of geocoded data collections. This paper investigates the use of image content local representations in geocoding tasks. Performed experiments demonstrate that some of the evaluated descriptors yield effective results in the task of geocoding VT building photos. This study is the first step to geocode multimedia material. Copyright © 2013 by the Association for Computing Machinery, Inc.
