Second-Order Growth Mixture Modeling in Organizational Psychology: An Application in the Study of Job Performance Using the Cusp Catastrophe Model
No full textIn recent years, research in organizational psychology has witnessed a shift inattention from a mostly variable-focused approach, to a mostly person-focused approach. Indeed, it has been widely recognized that the study of a sample’s heterogeneity is a meaningful and necessary task of researchers dealing with human behavior in organizational contexts. As a consequence, there has been growing interest in the application of statistical analyses able to uncover latent sub-groups of individuals. The present contribution was conceived as a tutorial for the application of one of these statistical analyses, namely second-order growth mixture modeling, and to illustrate its inner links with concepts from non-linear dynamic models. Throughout the paper, we provided (a) a discussion on the relationships between growth mixture modeling and the cusp catastrophe model; (b) Mplus syntaxes and output excerpts of a longitudinal analysis conducted on job performance (N = 420 employees rated once a year for four consecutive years); (c) an overview of two important topics regarding the correct implementation of growth mixture modeling (i.e., optimal number of classes and local maxima)
Vivere senza un lavoro. Positività e salute psicofisica in un campione di disoccupati
No full textQuesto studio esamina, in un campione di disoccupati, il ruolo della positività e la sua capacità di sostenere la salute mentale e fisica, diminuendo gli effetti dello stress economico percepito e promuovendo i comportamenti rilevanti per la salute. Sono stati intervistati 101 disoccupati (51.5% femmine) tra i 35 e i 45 anni con un disegno "cross-sectional". Tramite un Modello di Equazioni Strutturali, la positività è risultata positivamente associata alla salute mentale attraverso la diminuzione dello stress economico percepito e l'adozione dei comportamenti rilevanti per la salute. Tramite il rafforzamento di questi ultimi, la positività risulta intervenire anche sulla salute fisica. Vengono discussi implicazioni e limiti dello studio.This study examines the role of positivity in supporting mental and physical health in unemployed workers, reducing the effects of perceived economic stress and promoting health behaviors. Method. Cross-sectional data from 101 unemployed subjects (51.5% female) aged 35 to 45 regarding positivity, mental and physical health, perceived economic stress and health behaviors were collected, and were analyzed through a Structural Equation Model. Results. Positivity was positively associated with mental health in consequence of a reduction of the perceived economic stress and the adoption of health behaviors. Positivity was positively related with physical health as a result of adherence to health behaviors. Conclusions. Implications and limits are discussed
Il rammarico e la nostalgia degli immigrati romeni: un’indagine condotta a Roma e Terracina
No full textVari studi hanno sottolineato come gli immigrati e i rifugiati sperimentino elevati livelli di stress. Costoro si trovano a dover affrontare molte sfide, come cercare un’occupazione e un alloggio, adattarsi a una nuova cultura e costruire una nuova rete sociale, spesso in un contesto non privo di pregiudizi e discriminazioni. Tutti portano con sé la speranza di migliorare la propria vita e quella dei loro familiari, ma purtroppo molti non riescono a realizzare questo desiderio. Tale frustrazione può provocare un certo rammarico e portare a sperimentare nostalgia verso il proprio Paese di origine.
Questo studio ha l’obiettivo di verificare la relazione tra la nostalgia, il rammarico e i pensieri controfattuali, e anche di verificare quali sono le fonti di maggiore rammarico in un gruppo di immigrati romeni. Alla ricerca hanno partecipato 125 romeni che vivono a Roma e a Terracina. I risultati hanno evidenziato una relazione significativa tra il rammarico e la nostalgia, da una parte, e lo stress nel processo di integrazione dall'altra
The Antecedents of Risk Perception of Natural Hazards: A Meta-Analysis
No full textTo ensure better preparedness and response to natural hazards, involving people is
crucial. Among the determinants of individuals’ actions to protect themselves, both before
and after a natural hazard, is risk perception (van Valkengoed & Steg, 2019). A
conspicuous number of studies investigated the antecedents of risk perception;
nevertheless, there are no quantitative summaries (i.e., meta-analysis) of the available
research. The aim of this contribution is twofold, namely, to estimate effect sizes of
different potential antecedents of risk perception and to investigate the effect of possible
moderators of such relationships. A query string was used on Scopus, Web of Science,
and PsycINFO, and a final number of 121 records (127 studies) was included based on
the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)
guidelines. Results of the first aim showed that, among thirty-two predictors identified,
nineteen reported significant effect sizes. They can be organized into three clusters
(Bonaiuto & Ariccio, 2020): 1) factors related to the relationship individual-risk, 2) factors
related to the relationship individual-community, and 3) individual factors (i.e.,
sociodemographic and dispositional factors). The first cluster showed the highest number
of variables with strong effects. Overall, an effect of publication bias and study
heterogeneity was observed. Regarding moderators, the type of natural hazard
considered and the level of risk area of the sample proved to be relevant in some cases.
Existing research is scanty regarding some natural hazards (e.g., landslides, drought);
thus, future studies may consider studying risk perception antecedents in relation to these
understudied natural hazards. Policymakers should consider the three clusters of
antecedents. This represents a novel attempt to quantitatively summarize the available
literature on the topic of the determinants of risk perception, considering interdisciplinary
studies, including grey literature, and with no limits in terms of publication date
Test PeRS
No full textIl test PeRS è pensato per rilevare le principali risorse personali, ovvero le caratteristiche distintive di ogni persona, trasversali alle attività lavorative, che influiscono sulla prestazione e sul benessere individuale. Si tratta di predisposizioni, prospettive personali e inclinazioni comportamentali che possono essere rilevate e sviluppate in ambito organizzativo. Il PeRS misura le dimensioni che poggiano sulle più recenti teorie scientifiche, comprovate a livello internazionale e strutturalmente è diviso in tre sezioni. La prima sezione, “Risorse personali”, comprende cinque dimensioni: autoefficacia realizzativa, autoefficacia relazionale, determinazione, ottimismo, e resilienza: due di esse (ottimismo e resilienza), inoltre, si dividono ognuna in ulteriori due sottodimensioni (aspettative per il futuro e transitorietà per l’ottimismo, elasticità emotiva ed elasticità cognitiva per la resilienza). La seconda sezione, “Risorse in azione”, prevede invece una dimensione, quella del job crafting, a sua volta articolata in due sottodimensioni, proattività realizzativa e proattività relazionale. La terza sezione, “Tendenze alle distorsioni”, comprende infine quattro scale di controllo dedicate alla misura del livello di distorsione presente all’interno dei punteggi individuali restituiti dal PeRS; queste scale sono: fatalismo, strumentalità, self-presentation, e centratura su di sé

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
