Influence of proprioceptive information on space orientation on the ground and in orbital weightlessness
1989
Conscious space orientation depends on afferent information from different sense organs including the labyrinth, the eyes, tactile cues from the skin, joint receptors, muscle spindles, tendon organs and possibly viscera. An important role is played by impulses from the cervical position receptors in interaction with concomitant information from the otolith system. In order to isolate the effect of cervical position receptors from that of the otolith system, space experiments in orbital weightlessness and in parabolic aircraft flight were performed. It was found that stimulation of the neck receptors in weightlessness markedly influences the perception of the subjective vertical and horizont…
Factorial structure of recklessness: To what extent are older drivers different?
2003
This study tests whether the original factorial structure of a recklessness questionnaire can be maintained for the current Spanish population of older drivers.Our recent interest in dedicating special attention to senior citizen mobility (Monterde, 2001), is due to the impending increase of the aging population in Western countries; this has led us to reinitiate the psychometric study of the construct validity, revising and including older drivers in the psychometric aspects of those evaluation instruments that will then be used in the Spanish psycho-medical check of drivers and in research.Factorial analysis was used to determine validity.There was an appearance of a different psychologic…
Quality of Life and Job Loss during the COVID-19 Pandemic: Mediation by Hopelessness and Moderation by Trait Emotional Intelligence
2022
This study contributes to the knowledge on the effects of the COVID-19 pandemic by examining a moderated mediation model in which the impact of job loss over quality of life (QoL) is mediated by hopelessness and moderated by trait emotional intelligence (trait EI). Data were collected from a large nationally representative Italian sample of adult workers (N = 1610), who completed a series of anonymous online questionnaires. Total, direct and indirect effects were estimated through bootstrapped mediated moderation analyses providing 95% bias corrected bootstrap confidence intervals. After controlling for the effects of gender and age range, job loss was found to be negatively associated with…
Knowledge, attitudes, and practices about homelessness and willingness-to-pay for housing-first across 8 European countries: a survey protocol
2018
Contains fulltext : 200223.pdf (Publisher’s version ) (Open Access) Background: Most European countries report rising numbers of people experiencing homelessness. For those with mental disorders, interventions are centered on achieving mental health and drug rehabilitation alongside housing readiness, often to the detriment of access to housing. Notwithstanding, more European countries are investing in a new model, Housing First (HF), which postulates immediate access to permanent housing with no initial requirements for treatment. While results of the European HF programs are published on individual-level data, little is known about the opinions of the general population about homelessness…
Hopelessness and burnout in Italian healthcare workers during COVID-19 pandemic: the mediating role of trait emotional intelligence
2023
Objective: The study aims to assess the impact of COVID-19 on healthcare workers’ work-related stress during the first wave of the pandemic in Italy. The main objective is to investigate the existence of a positive correlation between hopelessness and burnout, assuming that burnout may be a riskfactor for the development of hopelessness, and to analyze the role thattrait Emotional Intelligence (TEI) and changes in workload could have in this relationship. Furthermore, evaluate any significant differences in burnoutand hopelessness levels in the function of some demographic variables, such as gender, professional profiles, and different working zones of Italy, tobetter understand how the di…
Episodic Breathlessness with and without Background Dyspnea in Advanced Cancer Patients Admitted to an Acute Supportive Care Unit
2020
Aim: To characterize episodic breathlessness (EB) in patients with advanced cancer, and to determine factors influencing its clinical appearance. Methods: A consecutive sample of advanced cancer patients admitted to an acute palliative care unit was surveyed. Continuous dyspnea and EB were measured by a numerical scale. The use of drugs used for continuous dyspnea and EB was recorded. Patients were asked about the characteristics of EB (frequency, intensity, duration and triggers). The Multidimensional dyspnea profile (MDP), the Brief dyspnea inventory (BDI), the Athens sleep scale (AIS) and the Hospital Anxiety and Depression Scale (HADS) were also administered. Results: From 439 advanced …
The role of success expectation and task-avoidance in academic performance and satisfaction: Three studies on antecedents, consequences and correlates
2003
Abstract To investigate the prospective relationships between individuals’ success expectation and task-avoidance, and their academic achievement and satisfaction, 231 students were examined yearly throughout their university careers in Study 1. It was found that students’ success expectation predicted academic achievement and satisfaction; which, in turn, increased their subsequent success expectation. Moreover, task-avoidance predicted low academic achievement and dissatisfaction, which again was predictive of subsequent task-avoidance. In Study 2, the task-avoidant behavior, and pre-examination anxiety, of 198 students who had participated in Study 1 were examined, and compared with thei…
Anxiety, cognitive interference, and sports performance: The cognitive interference test—table tennis
2000
Abstract Task-irrelevant cognitions manifested by athletes engaged in competition may interfere with the course of an ongoing contest. The self-confrontation method was applied to 18 table tennis players ranging from intermediate to expert level. By means of this method, various types of interfering cognitions present during competition were registered and then tentatively assigned to content-related categories. Based on the content of these cognitions, a sports-specific questionnaire was developed and administered to 149 table tennis players of various levels. Employing principal component analysis, three components could be interpreted: (a) worry, self-doubt, and distraction, (b) emotiona…
Transition from self tilt to object tilt during maintained lateral tilt in parabolic flight.
1991
Abstract 19 young healthy subjects were subjected to parabolic rollercoaster flight. A horizontal luminous line was seen by the subjects in a headfixed goggle device. During the hypergravic phases of parabolic flight the luminous line seemed to rotate into and during the hypogravic phase against the direction of static head tilt. Ocular counter rotation and activity of the neck position receptors cannot explain these subjective rotations. We conclude that information from the otolith system, converging with visual information within the brain, dislocated the headfixed visual target line. While the retinal image of the luminous line remains unchanged, loading and unloading the otoliths in pa…
Achievement Orientations, School Adjustment, and Well-being: A Longitudinal Study
2007
This study set out to identify the kinds of achievement orientations that adolescents show, and to examine the kinds of antecedents and consequences the use of a particular orientation has. The participants were 734 Swedish adolescents (335 boys and 399 girls) who filled in questionnaires measuring their achievement beliefs and behaviors, depressive symptoms, engagement with school, and norm-breaking behavior. By using clustering-by-cases analysis, five achievement orientation groups were identified: optimism, defensive-pessimism, self-handicapping, and learned helplessness, and a group showing average levels of criteria variables. The results showed further that a decrease in depressive sy…
