Analytical Solutions of Viscoelastic Nonlocal Timoshenko Beams
2022
A consistent nonlocal viscoelastic beam model is proposed in this paper. Specifically, a Timoshenko bending problem, where size- and time-dependent effects cannot be neglected, is investigated. In order to inspect scale phenomena, a stress-driven nonlocal formulation is used, whereas to simulate time-dependent effects, fractional linear viscoelasticity is considered. These two approaches are adopted to develop a new Timoshenko bending model. Analytical solutions and application samples of the proposed formulation are presented. Moreover, in order to show influences of viscoelastic and size effects on mechanical response, parametric analyses are provided. The contributed results can be usefu…
EmoTIC: Impact of a game-based social-emotional programme on adolescents
2021
[EN] Introduction Technologies provide a brilliant opportunity to promote social-emotional competences, well-being and adjustment in adolescence. Game-based programmes and serious games are digital tools that pursue an educational goal in an attractive environment for adolescents. The purpose of this study was therefore to determine the effectiveness of emoTIC, a game-based social-emotional programme designed according to Mayer, Caruso, and Salovey's model of emotional intelligence. Materials and methods The participants were 119 adolescents between 11 and 15 years, randomly assigned to the experimental group and the control group. The adolescents completed questionnaires to assess their em…
A cognitive-behavioural intervention improves cognition in caregivers of people with autism spectrum disorder: A pilot study
2017
Abstract As postulated by the stress process model, chronically stressed individuals, such as caregivers of people with chronic psychological disorders, have poorer cognitive performance and higher age-related cognitive decline than individuals not exposed to chronic stress. When analysing this topic in caregivers, the majority of research has been conducted in populations in which the care recipient has dementia and/or Alzheimer's disease, while relatively few studies have analysed cognition in caregivers of offspring with autism spectrum disorder (ASD). The main objective of this pilot study was to analyse the effect of a cognitive-behavioural intervention on cognition in caregivers of pe…
Reducing homework stress by increasing adoption of need-supportive practices: Effects of an intervention with parents
2020
Abstract Homework is widely recognized as a source of stress for both parents and children, but the underlying mechanisms remain unclear. This study tested the hypothesis that the frustration of the basic psychological needs for competence, autonomy and relatedness is the main source of stress and that satisfying these needs should reduce stress and lead to more positive outcomes. Study 1 assessed the associations between parental and child need frustration, homework stress and parental adoption of need-thwarting practices (n = 171 parent/child dyads). Study 2 tested the effectiveness of a four-session parental training (n = 55) program focused on helping parents increase their need-support…
From prematurity to parenting stress: The mediating role of perinatal post-traumatic stress disorder
2013
Preterm delivery may lead to the emergence of symptoms of Post-Traumatic Stress disorder (PTSD), which may, in turn, affect the quality of the mother-child relationship. The aim of this study is to shed light on the development of parenting stress in mothers of preterm and full-term children. It is hypothesized that PTSD symptoms mediate the relationship between preterm/full-term birth and the levels of parenting stress. Perinatal PTSD, parenting stress and social support were assessed in 156 mothers of full-term children and 87 mothers of preterm children. Mothers of preterm children experienced more post-traumatic stress and parenting stress than mothers of full-term children. However, th…
Economic stress and marital adjustment among couples: analyses at the dyadic level
2004
This survey study of 608 Finnish couples investigated the question of how economic stress is reflected in marital adjustment on the basis of the model presented by Conger and colleagues. We used the couple as a unit of analysis, performing a dyadic-level analysis within the framework of LISREL models. The model showed that the path by which economic circumstances were linked to marital adjustment was as follows: poor economic circumstances were linked to economic strain, which was related to increased psychological distress, and psychological distress in turn was negatively reflected in marital adjustment. However, psychological distress only partially mediated the link between economic str…
Do social comparison and coping styles play a role in the development of burnout? Cross-sectional and longitudinal findings
2006
The present longitudinal research among 558 teachers focused on the role of upward comparisons (with others performing better), downward comparisons (with others performing worse), and coping styles in relation to burnout. Assessed were identification (recognizing oneself in the other) and contrast (seeing the other as a competitor) in upward and downward comparison. Cross-sectionally, downward identification and upward contrast were positively related to burnout and negatively related to a direct coping style, whereas upward identification was negatively related to burnout and positively related to a direct coping style. Downward identification was positively related to a palliative coping…
Behavioral changes in male rats exposed to repeated aggression
2001
Research conducted on animal models has obtained information about the behavioral, hormonal, autonomic, neurochemical and immunological response in animals that are exposed to acute aggression by another conspecific animal. Research has also provided information about the pattern of adaptation that occurs when animals are repeatedly exposed to the experience of being attacked and defeated (for a review see1)
The Mental Health of Primary Care Physicians in Rhineland-Palatinate, Germany
2012
Physicians are subject to intense occupational stress (e1– e3), and long-term stress harms their well-being. Health impairments such as high blood pressure (e4), burnout syndrome (e5, e6), depression (1– 3), and substance dependencies (e2, e7) have been linked to occupational stress. One established approach to the assessment of occupational stress is the so-called occupational gratification crisis model (4, 5), according to which stress arises when persistent hard work (effort) does not yield a corresponding gratification (reward). Another important component of this model is a personality-based tendency to devote excessive effort to work, to the individual’s own detriment (“overcommitment…
Individual Differences in the Psychobiological Response to Psychosocial Stress (Trier Social Stress Test): The Relevance of Trait Anxiety and Coping …
2014
The main objective of this study was to investigate the contribution of some personality traits to the physiological and psychological response to a standardized laboratory psychosocial stressor (trier social stress test). Cortisol and affective response (anxiety and mood) were analysed in a mixed-sex group composed of 35 young adults who participated in a crossover design (18 men and 17 women). After verifying a statistically significant response to the trier social stress test in all parameters studied in both sex groups, exploratory cluster analyses were carried out to identify sub-groups based on their psychophysiological responses. These analyses showed two different groups: subjects d…
