Traits and emotions
2000
This paper reviews literature on traits and emotions focusing on both structure and management, or 'having' and 'doing'. The cognitive perspective of this paper implies that traits and emotions are viewed as provisions to frame people and their behaviours in situations in meaningful ways. The focus on the structure of traits thus implies considering the now broadly acknowledged Big Five model as a dimensional framework by which traits of people can be meaningfully organized. A similar position is taken with respect to emotions, given the recurrent finding of a two-dimensional model of emotions with Positive Affect and Negative Affect (PA and NA). Maintaining relevant distinctions between tr…
An efficient analytical approach for obtaining a five parameters model of photovoltaic modules using only reference data
2013
Exploiting the equivalent one-diode circuit of a photovoltaic (PV) module, this paper proposes a novel and fully analytical model to predict the electrical performance upon solar irradiance intensity and PV module temperature. The model refers essentially to an equivalent circuit governed by five parameters and the extraction of them permits to describe the current–voltage curve of the PV panel and consequently permits to assess the energy output of PV modules. The proposed model extracts the five characteristic parameters using only exact analytical relationship and tabular data always available such as short-circuit current, open circuit voltage and the Maximum Power Point (MPP). The diff…
Corrigendum to “A procedure to calculate the five-parameter model of crystalline silicon photovoltaic modules on the basis of the tabular performance…
2014
Only few manufactures provide the wide set of graphical data that are necessary to use high performance predictive tools for PV systems. On the other hand, reliable graphical data require accurate laboratory measurements that increase manufacturing costs. For this reason PV system designers have to choose between the use of cheap PV modules, lacking in technical data, and the reliable energy predictions that are possible only if the current–voltage characteristics are provided by the PV module manufacturers. This paper describes the procedure to evaluate the parameters of a one-diode equivalent circuit able to accurately epresent the electrical behaviour of a PV panel by means of the minimu…

Entrepreneurship attitudes and the Big Five: a cross-cultural comparison between Spain and the United States
2022
Abstract Culture may interact with personality to facilitate or inhibit entrepreneurial behaviors. 296 undergraduates in the United States and 257 in Spain completed the Big Five Personality Inventory and the Entrepreneurial Attitudes Scale for Students (Mean age = 20.16 years; SD = 3.39). We hypothesized that across cultures, conscientiousness and openness would predict greater risk taking whereas neuroticism and agreeableness would be a negative correlate. Personality variables explained a larger proportion of the variance in entrepreneurial attitudes in the U.S. data. The associations between the personality dimensions and entrepreneurship varied considerably by country and gender. Signi…
Counterdispositional Conscientiousness and Wellbeing: How Does Acting Out of Character Relate to Positive and Negative Affect at Work?
2020
Conscientiousness is typically seen as a positive or desired personality trait in the workplace, with the overall assumption being “the more, the better”. Drawing on the behavioral concordance model, we challenge this assumption, expecting that the highest level of positive affect and the lowest level of negative affect will correspond at the point where state and trait conscientiousness converge. Using an experience sampling study and an event reconstruction study, we show that deviations from one’s level of trait conscientiousness relate to variations in positive and negative affect, but not in a straightforward way. While wellbeing was lower when people behaved less conscientiously than …
Chanching the externalizing and internalizing spectrum of personality with self-regultaion therapy
2018
This article presents an integrator model of changes in the externalizing and internalizing factors of personality grouped in the General Factor of Personality (GFP), based on the Unique Trait Personality Theory (UTPT) [1]. This theory proposes that a continuum exists between personality and psychopathology, as well as the existence of a GFP that occupies the apex of the hierarchy of personality, and extends from an impulsiveness-and-aggressiveness pole (externalizing spectrum) to an anxiety-and-introversion pole (internalizing spectrum). With an experimental intra-group design, 30 regular users of stimulant drugs (cocaine and amphetamine) used the Self-Regulation Therapy (SRT). The SRT is …
Personality and reinforcement: An exploration using a maze-learning task
1995
A computerized maze learning task was investigated under control, reward and punishment, provided by differing financial reinforcement contingencies. The relationships between speed crossing the maze and anxiety and impulsivity personality traits were explored. Anxiety is hypothesized to reflect a behavioural inhibition system active in punishing environments; and impulsivity, to reflect an activation system active in rewarding environments. Of the measures of impulsivity taken, only one—venturesomeness from the I7—was associated significantly with increased maze crossing speed; this was found particularly in the reward condition and in males. Several anxiety variables were associated with …
Personality traits and parenting: neuroticism, extraversion, and openness to experience as discriminative factors
2003
This study used variable‐ and person‐oriented approaches to examine the relationship between personality traits (at age 33) and parenting (at age 36) among 94 mothers and 78 fathers. The SEM revealed that Openness to Experience (O), low Neuroticism (N), and Extraversion (E) were related to parental nurturance; low O to parental restrictiveness; and low N to parental knowledge about the child's activities. Cluster analysis based on the three parenting factors yielded six gender‐related parenting types with distinguishable personality profiles. Authoritative parents (mostly mothers) and emotionally involved parents (mostly fathers), who were high in nurturance and high to moderate in parenta…
Exploring non-cognitive predictors of mathematics achievement among 9th grade students
2017
Abstract This article explores the role of mathematics self-beliefs, as well as personality traits, social attitudes and well-being in students' mathematics achievement. The analysis builds on a Web survey of 9th grade students in Latvia (N = 3083). Based on a hierarchical multilevel regression analysis we find that personality, social attitudes and wellbeing variables matter more for mathematics achievement than sociodemographic variables, yet mathematics self-beliefs account for an even larger amount of variance over and above that accounted for by sociodemographic variables and personality, social attitudes and well-being. Mathematics self-beliefs, most of all mathematics self-concept, w…
