A Bi-objective Optimization Study of an Acid-Base Flow Battery for High Efficiency and Improved Power Density
2022
Electrical energy storage is critical for a broader penetration of renewable energies with intermittent nature, such as solar and wind energy. The Acid/Base Flow Battery (AB-FB) is a unique, sustainable, and environmental-friendly storage technology with high electrolyte solution energy density. The method relies on reversible electrodialytic technologies using bipolar membranes to transform electrical energy into chemical energy related to pH gradients and vice versa. The charge phase is accomplished by using bipolar membrane electrodialysis, whereas the discharge phase is performed via bipolar membrane reverse electrodialysis. In a previous work, we developed an advanced multi-scale proce…
Type-2 Fuzzy Control of a Bioreactor
2009
Abstract—In this paper the control of a bioprocess using an adaptive type-2 fuzzy logic controller is proposed. The process is concerned with the aerobic alcoholic fermentation for the growth of Saccharomyces Cerevisiae a n d i s characterized by nonlinearity and parameter uncertainty. Three type-2 fuzzy controllers heve been developed and tested by simulation: a simple type-2 fuzzy logic controller with 49 rules; a type-2 fuzzyneuro- predictive controller (T2FNPC); a t y p e -2 selftuning fuzzy controller ( T2STFC). The T2FNPC combines the capability of the type-2 fuzzy logic to handle uncertainties, with the ability of predictive control to predict future plant performance making use of a…
How Do Religiosity and Spirituality Associate with Health-Related Outcomes of Adolescents with Chronic Illnesses? A Scoping Review.
2022
The aim of the current scoping review was to explore the associations between religious and spiritual factors and the health-related outcomes of adolescents with chronic illnesses, as well as to investigate possible mechanisms accounting for these relationships. In total, 20 studies meeting the eligibility criteria were reviewed after performing a search of the Scopus, Web of Science, and PubMed databases. The results suggested that religious and spiritual beliefs, thoughts, and practices (e.g., spiritual coping activities) might have both beneficial and deleterious effects on the way adolescents deal with their medical condition, on their psychosocial adjustment, on their mental and physic…
Sociodemographic and psychological correlates of COVID-19 vaccine hesitancy and resistance in the young adult population in Italy.
2021
Background: Previous research has shown that young adults are more hesitant/resistant to COVID-19 vaccine uptake than older age groups, although the factors underlying this tendency are still under debate. The current study aimed to identify the sociodemographic and psychological correlates of vaccine hesitancy and resistance among young adults (18–40 years) during the nationwide COVID-19 vaccination campaign in Italy, the first country after China being hit by the pandemic and which suffered a large number of fatalities. Methods: This is a cross-sectional, web-based study conducted in Italy using an ISO-certified international survey company (respondi.com). Data were collected on 1200 part…
Personal conceptions of intelligence, self-esteem, and school achievement in Italian and Portuguese students.
2007
Educational research places emphasis on the fact that different cultures have different self-construals. These construals can influence cognitive, emotional, and motivational processes in individuals. Great importance is attached to individuals' implicit conceptions of the nature of their intelligence (incremental or entity) and self-esteem. In general, both representation of intelligence and self-esteem seem to play an important role in scholastic performance in terms of both a predispostion to learning and the results actually achieved. The aim of this research is to determine the relationship between variables such as school, and socioeconomic level and gender in Italian and Portuguese s…
Associations Among Psychologically Controlling Parenting, Autonomy, Relatedness, and Problem Behaviors During Emerging Adulthood.
2017
ABSTRACTThe present study aimed to investigate the relations among perceived parental psychological control (PPC), autonomy and relatedness, and negative outcomes during emerging adulthood in two cultural contexts: Italy and the USA. More specifically, we explored the mechanisms through which dependency-oriented PPC (DPPC) and achievement-oriented PPC (APPC) are associated with both internalizing and externalizing difficulties, focusing on the mediating role of autonomy and relatedness. Participants were 418 European-American and 359 Italian college students. Results indicated that the expressions of PPC with regard to dependency and achievement were related to emerging adults’ negative out…
A Study of Maternal Competence in Preterm Birth Condition, during the Transition from Hospital to Home: An Early Intervention Program’s Proposal
2021
The study was conducted with 104 mothers (average age 32.5 years, SD 6.1) of preterm infants (very and moderately preterm but still healthy) to monitor the perceived maternal role competence from the time of hospitalisation to post-discharge, in order to define an intervention program to support mothers during this transition. A targeted Q-Sort tool (Maternal Competence Q-Sort in preterm birth) was applied at two different times as a self-observation tool for parenting competence in neonatology. A tendency towards dysregulation of the maternal role competence was detected, mainly in terms of low self-assessment and was found to worsen during post-discharge, particularly with regard to careg…
Mediating and moderating processes in the relationship between multicultural ideology and attitudes towards immigrants in emerging adults
2015
Few studies examine intercultural relations in emerging adulthood. Framed from the perspective of the Mutual Intercultural Relations in Plural Societies (MIRIPS) project, the current paper examined the mediating role of tolerance and perceived consequences of immigration in the relationship between multicultural ideology and attitudes towards immigrants. Additionally, the moderating role of context was analysed. A two-group structural equation modelling was performed on data collected from 305 Italian emerging adults living both in northern and in southern Italy with different socio-political climates towards immigrants. In both groups, tolerance and perceived consequences of immigration me…
Physical Activity Engagement in Young People with Down Syndrome: Investigating Parental Beliefs
2015
Background Despite the wide documentation of the physical/psychological benefits derived from regular physical activity (PA), high levels of inactivity are reported among people with Down syndrome. This study aims to explore parental beliefs concerning involvement, facilitators/barriers and benefits of PA in young people. Method Semi-structured interviews were conducted with 13 parents of young people with Down syndrome. Results Three facilitation themes were identified: (i) the support derived from family; (ii) the availability of APA (Adapted Physical Activity) expert instructors and coaches; (iii) the challenging nature of sport activities. Three barrier themes were identified: (i) the l…
The Basic Psychological Need Satisfaction and Frustration Scale: Construct and Predictive Validity in the Italian Context
2020
The Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS) is a self-report instrument assessing the satisfaction and frustration of the three basic psychological needs of autonomy, competence, and relatedness defined by self-determination theory. The aim of this study was to examine the dimensionality, the predictive validity, and the measurement invariance across different age groups of the Italian version of the BPNSFS. The participants were 2,204 Italian adolescents and young adults (41% males) from 14 to 28 years old (M age = 20.23, SD = 4.25). The invariance across age demonstrated adequate equivalence of the 6-factor model of scales across adolescents (14–18 years) and …
