Legacy of wood charcoal production on subalpine forest structure and species composition.

Land-use legacy on forest dynamics at both stand and landscape scale can last for centuries, affecting forest structure and species composition. We aimed to disentangle the history of the charcoal production legacies that historically shaped Mont Avic Natural Park (Aosta Valley, Italy) forests by integrating LiDAR, GIS, anthracological, and field data at the landscape scale. We adopted different geostatistical tools to relate geographic layers from various data sources. The overexploitation due to intensive charcoal production to fuel mining activities shaped the current forests by homogenising their structure and species composition into dense and young stands with a reduction in late seral species such as Norway spruce (Picea abies) and an increase in pioneer species such as Mountain pine (Pinus uncinata). The multidisciplinary and multi-scale framework adopted in this study stresses the role of historical landscape ecology in evaluating ecosystem resilience to past anthropogenic disturbances.

Models of Disability in Children's Pretend Play: Measurement of Cognitive Representations and Affective Expression Using the Affect in Play Scale.

Play is a natural mode of children's expression and constitutes a fundamental aspect of their life. Cognitive, affective, and social aspects can be assessed through play, considered as a "window" to observe a child's functioning. According to Russ's model, cognitive and affective components and their reciprocal connections can be assessed through the Affect in Play Scale (APS). The aim of the present study was to investigate children's representations of the three main models of disability (medical, social, and biopsychosocial) and how these models affected cognitive and affective components of children's play. Sixty-three children, aged 6-10 years, were assessed by means of the APS. Participants were randomly assigned to one of two APS task orders: the standard APS task followed by the modified APS task (including a wheelchair toy), or vice versa. The standard and modified APS sessions were coded according to the APS system. The modified APS sessions were also coded for the model of disability expressed by children. A one-way ANOVA conducted on the APS affective and cognitive indexes revealed an effect of condition on the affective components of play and no effect on cognitive components and variety of affect as assessed by the APS. In addition, when children are involved in pretend play from which concepts of disability emerge, these concepts are almost exclusively related to the medical model of disability. Results suggested implications for intervention with children in educational contexts that aim to teach children about disability.

World Health Organization disability assessment schedule 2.0: An international systematic review.

PURPOSE: This systematic review examines research and practical applications of the World Health Organization Disability Assessment Schedule (WHODAS 2.0) as a basis for establishing specific criteria for evaluating relevant international scientific literature. The aims were to establish the extent of international dissemination and use of WHODAS 2.0 and analyze psychometric research on its various translations and adaptations. In particular, we wanted to highlight which psychometric features have been investigated, focusing on the factor structure, reliability, and validity of this instrument. METHOD: Following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) methodology, we conducted a search for publications focused on "whodas" using the ProQuest, PubMed, and Google Scholar electronic databases. RESULTS: We identified 810 studies from 94 countries published between 1999 and 2015. WHODAS 2.0 has been translated into 47 languages and dialects and used in 27 areas of research (40% in psychiatry). CONCLUSIONS: The growing number of studies indicates increasing interest in the WHODAS 2.0 for assessing individual functioning and disability in different settings and individual health conditions. The WHODAS 2.0 shows strong correlations with several other measures of activity limitations; probably due to the fact that it shares the same disability latent variable with them. Implications for Rehabilitation WHODAS 2.0 seems to be a valid, reliable self-report instrument for the assessment of disability. The increasing interest in use of the WHODAS 2.0 extends to rehabilitation and life sciences rather than being limited to psychiatry. WHODAS 2.0 is suitable for assessing health status and disability in a variety of settings and populations. A critical issue for rehabilitation is that a single "minimal clinically important .difference" score for the WHODAS 2.0 has not yet been established.

The abandonment of assistive technology in Italy: a survey of National Health Service users.

BACKGROUND: This study was an extension of research which began in the Umbria region in 2009. AIM: To investigate the extent to which assistive technology (AT) has been abandoned by users of the Italian National Health Service (ULHS) and the reasons for this. DESIGN: Observational study. SETTING: Users who received a hearing device (HD) or mobility device (MD) by ULHS between 2010 and 2013. POPULATION: 749 out of 3,791 ULHS users contacted via telephone completed the interview: 330 (44.06%) had a HD and 419 (55.94%) a MD. METHODS: Data were collected using a specially developed telephone interview questionnaire including the Italian version of the Quebec User Evaluation of Satisfaction with AT (QUEST 2.0) and Assistive Technology Use Follow-up Survey (ATUFS). RESULTS: 134 users (17.9%) were no longer using their assigned AT device within seven months of issue and 40% of this group reported that they had never used the device. Duration of use (for how long the AT device was used before abandonment) and satisfaction with service delivery did not predict AT abandonment. People who received a HD where more likely to abandon their device (22.4%) than those who received a MD (14.4%). CONCLUSIONS: Abandonment may be due to assignment of inappropriate devices or failure to meet user needs and expectations. These findings are consistent with previous data collected by Federici and Borsci in 2009. Utility of AT in use, reasons of abandonment, and importance of device and service satisfaction for the use or non-use of an AT are presented and discussed. CLINICAL REHABILITATION IMPACT: AT abandonment surveys provide useful information for modelling AT assessment and delivery process. The study confirms the relevance of person centredness approach for a successful AT assessment and delivery process.

The effectiveness of powered, active lower limb exoskeletons in neurorehabilitation: A systematic review.

OBJECTIVE: This review examines the utility of current active, powered, wearable lower limb exoskeletons as aids to rehabilitation in paraplegic patients with gait disorders resulting from central nervous system lesions. METHODS: The PRISMA guidelines were used to review literature on the use of powered and active lower limb exoskeletons for neurorehabilitative training in paraplegic subjects retrieved in a search of the electronic databases PubMed, EBSCO, Web of Science, Scopus, ProQuest, and Google Scholar. RESULTS: We reviewed 27 studies published between 2001 and 2014, involving a total of 144 participants from the USA, Japan, Germany, Sweden, Israel, Italy, and Spain. Seventy percent of the studies were experimental tests of safety or efficacy and 29% evaluated rehabilitative effectiveness through uncontrolled (22%) or controlled (7%) clinical trials. CONCLUSIONS: Exoskeletons provide a safe and practical method of neurorehabilitation which is not physically exhausting and makes minimal demands on working memory. It is easy to learn to use an exoskeleton and they increase mobility, improve functioning and reduce the risk of secondary injury by reinstating a more normal gait pattern. A limitation of the field is the lack of experimental methods for demonstrating the relative effectiveness of the exoskeleton in comparison with other rehabilitative techniques and technologies.

Parents' Education Shapes, but Does Not Originate, the Disability Representations of Their Children.

The present research tested whether children's disability representations are influenced by cultural variables (e.g., social activities, parent education, custom complex variables) or by cognitive constraints. Four questionnaires were administered to a sample of 76 primary school aged children and one of their parents (n = 152). Questionnaires included both open-ended and closed-ended questions. The open-ended questions were created to collect uncensored personal explanations of disability, whereas the closed-ended questions were designed to elicit a response of agreement for statements built on the basis of the three most widespread disability models: individual, social, and biopsychosocial. For youngest children (6-8 years old), people with disabilities are thought of as being sick. This early disability representation of children is consistent with the individual model of disability and independent from parents' disability explanations and representations. As children grow older (9-11 years old), knowledge regarding disability increases and stereotypical beliefs about disability decrease, by tending to espouse their parents representations. The individual model remains in the background for the adults too, emerging when the respondents rely on their most immediately available mental representation of disability such as when they respond to an open-ended question. These findings support that the youngest children are not completely permeable to social representations of disability likely due to cognitive constraints. Nevertheless, as the age grows, children appear educable on perspectives of disability adhering to a model of disability representation integral with social context and parent perspective.

World Health Organisation Disability Assessment Schedule II: contribution to the Italian validation.

INTRODUCTION: The World Health Organisation Disability Assessment Schedule II (WHODAS II) is an instrument developed by the World Health Organisation in order to assess behavioural limitations and restrictions to participation experienced by an individual, independently from a medical diagnosis. The conceptual frame of reference of this instrument is the International Classification of Functioning, Disability and Health: ICF. Specifically, the instrument is designed to evaluate the functioning of the individual in six activity domains: Understanding and communicating, Getting around, Self-care, Getting along with people, Life activities, Participation in society. PURPOSES: Considering the widespread consent about the usefulness of the WHODAS II, the general aim of the present study is to provide a contribution to the validation of the Italian version. METHOD: The WHODAS II Italian version has been administered to a sample of 500 participants subdivided in two groups: 271 normal adults and 229 disabled adults. The disabled participants group has been subdivided in three sub-groups, according to their disability: 111 motor disabled, 45 mental disabled, 73 sensory disabled. RESULTS: The mean Total score of the WHODAS II is 12.95 for the normal adults and 22.93 for the disabled group. Either group obtains the least impairment in the Self-care domain. This could be probably due to the presence of social-health workers in everyday life for all Italian disabled people. For the three disabled participant groups separately computed the mean Total score is: 28.66 for the motor disabled, 24.60 for the mental disabled, and 14.97 for the sensory disabled, confirming that sensory disabled do not perceive their disability as a personal functioning problem but a socially constructed one. Some subscales of WHODAS II show relatively strong floor effects. The Cronbach's Alpha calculated for each of the subscales is found to be high. The correlations of the subscales show strong correlations in all subscales. CONCLUSIONS: The WHODAS II is a useful instrument for measuring disability and functioning in normal and disabled people. It shows high reliability and a stable factor structure; although an additional psychometric evaluation of a representative sample of Italian disabled should be carried out in order to reach standard scores for each macro-category of disability.
