The Predictive Role of Ideological, Personality and Psychopathological Factors in Homonegative Attitudes in Italy
2021
Homonegativity refers to a series of prejudicial and discriminatory attitudes towards individuals perceived as homosexuals. Previous studies indicated that some person- ality traits (i.e., neuroticism, low openness to experience), as well as specific ideo- logical attitudes (i.e., conservatism, authoritarianism) and higher levels of psychopa- thology make individuals more prone to show homonegative attitudes. However, no studies have compared these three dimensions in order to identify their different role in homonegativity. For this reason, the aim of this study was to simultaneously eval- uate the association of ideological, personality, and psychopathological factors with homonegativity …
Coping Trajectories from Adolescence to Young Adulthood: Links to Attachment State of Mind
2005
The objective of this study was to examine the links between coping and attachment. In a longitudinal study of 112 participants, coping behavior was assessed at five points in time during adolescence (starting at the age of 14 years) and early adulthood. In addition, at the age of 21 years, state of mind regarding current and earlier attachment experiences was assessed by employing the Adult Attachment Interview (AAI). In both adolescence and early adulthood, differences in coping styles were found to be related to differences in attachment. Individuals classified as secure dealt with their problems more actively by using their social network during adolescence and at the age of 21 years. B…
Cross‐national outcomes of stress appraisal
2012
PurposeThe present study aims to analyze the role of the appraisal of stressors as harmful and threatening (distress) and/or as opportunities and challenges (eustress) in inducing negative (burnout) and positive (engagement) effects. It compares appraisal of occupational stressors in Poland and Spain and looks for differences between these countries in the associations between different types of appraisals and their positive and negative outcomes.Design/methodology/approachThe study analyzes the equivalence of relations across cultures by constraining structural equation models to be equivalent across the Spanish (n=603) and Polish (n=147) data sets of social care services employees. Multig…
Development of School and Sport Burnout in Adolescent Student-Athletes: A Longitudinal Mixed-Methods Study.
2018
We investigated the development of school and sport burnout in adolescent student-athletes (N Time 1 = 391, N Time 2 = 373) during their first year in upper secondary school using an embedded mixed-methods design. The questionnaire-based data were analyzed with growth mixture modeling and four burnout profiles were identified among student-athletes. From the found burnout profiles, two were typical for the interviewed subsample of elite athletes (n = 17), that is, burnout risk and non risk profiles. We generated rich descriptions of well-being and ill-being, showing that elite athletes in two burnout profiles differed in their experienced demands and resources related to individual and envi…
Be congruent and I will be loyal: the case of sport services
2019
This research analyzes the relationship between brand perception of users of a sports service and their levels of loyalty. Data were treated with both SPSS 23 and EQS 6.3, using CFA to confirm reliability and validity and creating a model to be tested. Congruence explain 43% of credibility and that these two variables explain up to 73% of trust. Credibility and trust can explain up to 73% of the attitudes, while attitudes would explain up to 50% of loyalty. In the case of sports services, brand perception and its relationship with loyalty remain largely unaddressed. For this reason, it is interesting to carry out research on this subject, bringing new evidence to business reality to help ma…
Establishing Video Game Genres Using Data-Driven Modeling and Product Databases
2015
Establishing genres is the first step toward analyzing games and how the genre landscape evolves over the years. We use data-driven modeling that distils genres from textual descriptions of a large collection of games. We analyze the evolution of game genres from 1979 till 2010. Our results indicate that until 1990, there have been many genres competing for dominance, but thereafter sport-racing, strategy, and action have become the most prevalent genres. Moreover, we find that games vary to a great extent as to whether they belong mostly to one genre or to a combination of several genres. We also compare the results of our data-driven model with two product databases, Metacritic and Mobyga…
3D survey and modelling of the main portico of the Cathedral of Monreale
2018
3D survey and modelling of Cultural Heritage allow to store a great deal of 3D data that can be managed for different purposes. 3D models can be used for documentation, restoration and knowledge of historic architectures and monuments. In this work, a 3D survey of the main portico of the Cathedral of Monreale (Palermo, Italy) was carried out. The paper presents the data acquisition process and the 3D modelling phase. The work is aimed to reconstruct a 3D model that could be used also to set up an HBIM (Heritage or Historic Building Information Modelling) of the main portico. The result of this study could be considered as a first test to implement an HBIM platform for the whole monumental c…
The possibilities of using broadleaf cattail seeds (Typha latifolia L.) as super absorbents for removing aromatic hydrocarbons (BTEX) from an aqueous…
2018
Sorption of oil-related products (including mainly the propellants) is the very basic process that counteracts spreading these types of pollution into environment. Plenty of synthetic substances (including the monoaromatic hydrocarbons) are both from the surface and underground waters. The aim of this study was to present the research’s results on the possibilities of using the broadleaf cattail (Typha latifolia L.) seeds as a sorbent of monoaromatic hydrocarbons from an aqueous solution. In order to increase sorptive capacity, the seeds biomass was submitted for the process of mercerizing in diversified time and temperature in water and the NaOH solution. The removal of benzene, toluene, e…
An improved smoothed particle electromagnetics method in 3D time domain simulations
2011
In this paper, an enhanced variant of the meshless smoothed particle electromagnetics (SPEM) method is performed in order to solve PDEs in time domain describing 3D transient electromagnetic phenomena. The method appears to be very efficient in approximating spatial derivatives in the numerical treatment of Maxwell's curl equations. In many cases, very often, accuracy degradation, due to a lack of particle consistency, severely limits the usefulness of this approach. A numerical corrective strategy, which allows to restore the SPEM consistency, without any modification of the smoothing kernel function and its derivatives, is presented. The method allows to restore the same order of consiste…
E.O.-based estimation of transpiration and crop water requirements for vineyards: a case study in southern Italy
2014
An efficient use of water for irrigation is a challenging task. From an agronomical point of view, it requires establishing the optimal amount of water to be supplied, at the correct time, based on phenological phase and water stress spatial distribution. Indeed, the knowledge of the actual water stress is essential for agronomic decisions, vineyards need to be managed to maintain a moderate water stress, thus allowing to optimize berries quality and quantity. Methods for quickly quantifying where, when and in what extent, vines begin to experience water stress are beneficial. Traditional point based methodologies, such those based on Scholander pressure chamber, even if well established ar…
