MULTICRITERIA OPTIMAL DESIGN OF CONTINUOUS CIRCULAR PLATES
2010
The paper is devoted to a quite general version of the multicriteria optimal (minimum volume) design of axisymmetric circular plates. The constitutive material is considered as elastic perfectly plastic without any ductility limit and the actions are assumed as quasi-statically variable within a given load domain. In the design problem formulation different resistance criteria are considered, in order to investigate all the possible structural limit responses, and for each one a suitably chosen safety factor is chosen. The optimal design problem is formulated as the search for the minimum structure volume according with a statical approach. The features of the optimal structures will be stu…
Influence of protecting devices on the optimal design of elastic plastic structures
2008
The paper concerns the minimum volume design of structures constituted by elastic perfectly plastic material. The relevant optimal design problem is formulated on the grounds of a statical approach and two different resistance limits are considered: in particular, it is required that the optimal structure satisfies the elastic shakedown limit and the instantaneous collapse limit, imposing for each different condition a suitably chosen safety factor. For sake of generality, the structure is thought as discretized into compatible finite elements and subjected to loads quasi-statically acting as well as to dynamic (seismic) loads. The effects of the dynamic actions are studied on the grounds o…
THE ENTREPRENEURS’ PROPENSITY TO ADOPT ELECTRIC MOBILITY IN THE SHORT FOOD SUPPLY CHAIN
2019
In the last years, Short Food Supply Chain (SFSC) has gained relevant attention among the consumers, for its characteristics of environmental, economic and social sustainability. At the same time, recently some doubts has been raised about the environmental negative impacts that also SFSC is causing, despite the intrinsic “local” label. In particular, the reference is on the transport system and related CO2 emissions of SFSC that undermines the full achievement of environmental concerns. To deal with this challenge, electric vehicles (EVs) are seen as a viable and very promising alternative. Starting from these considerations, this study investigates the propensity of entrepreneurs operatin…
The Impact of Using Measurements of Electrodermal Activity in the Assessment of Problematic Behaviour in Dementia
2018
Background: A major and complex challenge when trying to support individuals with dementia is meeting the needs of those who experience changes in behaviour and mood. Aim: To explore how a sensor measuring electrodermal activity (EDA) impacts assistant nurses’ structured assessments of problematic behaviours amongst people with dementia and their choices of care interventions. Methods: Fourteen individuals with dementia wore a sensor that measured EDA. The information from the sensor was presented to assistant nurses during structured assessments of problematic behaviours. The evaluation process included scorings with the instrument NPI-NH (Neuropsychiatric Inventory-Nursing Home version), …
Behavioural Consequences of P-Glycoprotein Deficiency in Mice, with Special Focus on Stress-Related Mechanisms
2012
P-glycoprotein (P-gp), an efflux transporter localised in the blood-brain barrier, limits the access of multiple xenobiotics to the central nervous system. Whether it is also implemented in the transport of the endogenous glucocorticoid corticosterone is a matter of debate. The P-gp knockout mouse model [abcb1a/b (-/-)] has been shown to differ in the functioning of the hypothalamic-pituitary adrenal (HPA) axis. In the present study, we investigated the behaviour of abcb1a/b (-/-) and wild-type mice with respect to stress-related tests and the effects of corticosterone. Behavioural activities were assessed in the open field (OF) test for 4 days, and in the forced swimming test (FST) and tai…
Intérêt en EHPAD du robot émotionnel Pepper dans les troubles neurocomportementaux de la maladie d’Alzheimer
2021
International audience; Can geriatric technologies really be effective among elderly people with Alzheimer's dementia and living in institutions? Our controlled, randomized, single-blind, comparative study attempted to answer this question. The study was conducted in two nursing homes among 31 subjects with an average age of 79.4 ± 6.9, and an average MMSE score of 12.2 ± 3.6. The results show that the Pepper robot, compared to a soft toy, is capable not only of entertaining, but above all of inducing qualitative and quantitative clinical effects. During the 20-minute sessions, a decrease in apathy was observed with Pepper (6.7 ± 6.5 min vs. 18.4 ± 3.8 min, P < 0.001), a decrease in ambulat…
Attentional biases towards emotional scenes in autism spectrum condition: An eye-tracking study.
2021
Abstract Background Different attentional processing of emotional information may underlie social impairments in Autism Spectrum Condition (ASC). It has been hypothesized that individuals with ASC show hypersensitivity to threat, which may be related to an avoidance behaviour. However, research on the attentional processing of emotional information in autism is inconclusive. Aim To examine the attentional processing biases of 27 children with ASC and 25 typically developed (TD) participants. Methods and procedures The initial orienting of attention, the attentional engagement, and the attentional maintenance to complex emotional scenes in competition (happy, neutral, threatening, sad) were …
Group analytic therapy for eating disorders: preliminary results in a single-group study.
2008
Objectives There is a lack of empirical data on the effectiveness and process of group-analytic therapy in eating disorders. This single-group study aimed to explore the effectiveness of such treatment for anorexic and bulimic individuals. Method Eight patients (three anorexic and five bulimic women) entered group-analytic treatment, meeting weekly for 2 years. Eating behaviours, overall psychological distress and group process variables were regularly assessed using quantitative and qualitative measures, with comparisons made at the beginning and end of the therapy. Results Treatment was discontinued in two cases. When outcome was classified on the basis of reliable change and clinical sig…
Key Predictors of Customer Loyalty for Facebook Brand Pages. Empirical Research on Social Media Marketing
2018
The new marketing practices and developments have had incredible impact on consumers’ purchasing process and information-acquisition process, and most notably, social media is changing marketing. The research setting for this paper refers to consumer behavior on social media services, particularly Facebook and consumers’ interactions with brands on this social platform. Through this research, we examine which consumer behavior concept has a higher impact in generating loyalty for the brands consumers interact with on Facebook. Using Automatic Linear Modeling, we forecast and model a target variable (namely, consumer loyalty) based on linear relationships between the target variable and its …
