Radiation source rate estimation through data assimilation of gamma dose rate measurements for operational nuclear emergency response systems

This paper presents an evaluation of an innovative data assimilation method that has been recently developed in NCSR Demokritos for estimating an unknown emission rate of radionuclides in the atmosphere, with real-scale experimental data. The efficient algorithm is based on the assimilation of gamma dose rate measured data in the Lagrangian atmospheric dispersion model DIPCOT and uses variational principles. The DIPCOT model is used in the framework of the nuclear emergency response system (ERS) RODOS. The evaluation is performed by computational simulations of dispersion of Ar-41 that was emitted routinely by the Australian Nuclear Science and Technology Organisation’s (ANSTO) previous research reactor, HIFAR, located in Sydney, Australia. In this paper the algorithm is evaluated against a more complicated Radiation source rate estimation through data assimilation 387 case than the others used in previous studies: There was only one monitoring station available each day and the site topography is characterised as moderately complex. Overall the estimated release rate approaches the real one to a very satisfactory degree as revealed by the statistical indicators of errors. © 2012 Inderscience Enterprises Ltd

Brief Report: Using Individualized Orienting Cues to Facilitate First-Word Acquisition in Non-Responders with Autism

Though considerable progress has been made in developing techniques for improving the acquisition of expressive verbal communication in children with autism, research has documented that 10–25% still fail to develop speech. One possible technique that could be significant in facilitating responding for this nonverbal subgroup of children is the use of orienting cues. Using a multiple baseline design, this study examined whether individualized orienting cues could be identified, and whether their presentation would result in verbal expressive words. The results suggest that using individualized orienting cues can increase correct responding to verbal models as well as subsequent word use. Theoretical and applied implications of orienting cues as they relate to individualized programming for children with autism are discussed

Does long-term group psychoeducation of parents of individuals with schizophrenia help the family as a system? A quasi-experimental study

A chronic illness like schizophrenia seriously disrupts family functioning in various ways that can be addressed through family psychoeducational interventions in routine clinical services, an approach that has not received proper research attention. We pre- and post-tested four sets of parents of individuals with schizophrenia who participated in a long-term group psychoeducational intervention (treatment group) and four sets of parents of individuals with schizophrenia who received standard outpatient services (clinical control group), using three self-reported questionnaires to measure family functioning (Family Assessment Device), family atmosphere (Family Rituals Scale), and family burden (Family Burden Scale). At pre-test, there were no systematic differences between the two groups in any of the parameters assessed. At post-test, within and across groups, comparisons revealed significant improvements (under cut-off scores) in the mean scores of the treatment group (p < 0.05) in all three parameters under study. Our findings provide pilot evidence that intensive group parent psychoeducation is an efficient and efficacious treatment intervention for improvement of systemic properties of families, such as family functioning, family atmosphere, and family burden. © 2015 Copyright © Taylor & Francis Group, LLC

Self-efficacy, stress levels and daily style of living among older patients with type 2 diabetes in a rural primary care setting: a cross-sectional study

Aims. To identify to what extent stress and self-efficacy may be associated with specific features in the elderly with type 2 diabetes, such as lifestyle habits, multimorbidity, sleep quality and duration, and treatment regimen. Methods. A cross-sectional study of 92 out of 103 recruited patients ≥65 year old with a diagnosis of type 2 diabetes was conducted at a rural primary care unit in Northern Greece. The General Self-Efficacy Scale (GSES), the Short Anxiety Screening Test (SAST) and an original questionnaire to assess health habits and disease monitoring information were completed after structured personal interviews. Results. In the multiple linear regression analysis, patients with higher education, with more night sleeping hours and physical exercise weekly had a higher GSES score than their counterparts (p<0.05). Stress levels assessed with SAST were shown mostly associated with poor sleep quality, fewer days of meat and legumes consumption, increased body mass index and multi-morbidity (p<0.05), as emerged from the multiple linear regression analysis. Glycemic control in the elderly does not have a significant correlation with stress levels or general self-efficacy. Conclusions. Self-efficacy and stress levels are not predictors for glycemic control, but can indirectly be seen as co-determinants, contributing to the overall daily life quality among patients with diabetes. Mental health well-being, expressed by higher self-efficacy and less stress scale rating, showed positive interferences with eating, sleep and daily life attitudes among elderly with diabetes. © 2022.
