    In light of the increasing propensity toward unsportsmanlike behaviours that have caused the failure of the notion of fair play, this research tested a causal model of theoretically-predicted antecedents of sportspersonship, in which the two trait-related personality factors, self-control and aggressiveness, mediated the relationship between motivational orientations and sportspersonship. After examining the five-factor structure of the Multidimensional Sportspersonship Orientation Scale in a first sample of Italian athletes (n = 371, M age = 26.57), the resulting 20-item four-factor model proved to be satisfactory and reliable. In a second sample (n = 814, M age = 25.96) the proposed empirically-based model confirmed the important role played by self-control in mediating the relationship between ego orientation, aggressiveness, and sportspersonship. In terms of practical implications, the findings provide a more comprehensive conceptualization of the factors that differentiate the inter- and intra-individual characteristics in sportspersonship, thus allowing practitioners to develop effective intervention programs addressed to athletes

    Synthesis of NH-sulfoximines from sulfides by chemoselective one-pot N- and O-transfers

    Get PDF
    Direct synthesis of NH-sulfoximines from sulfides has been achieved through O and NH transfer in the same reaction, occurring with complete selectivity. The reaction is mediated by bisacetoxyiodobenzene under simple conditions and employs inexpensive N-sources. Preliminary studies indicate that NH-transfer is likely to be first, followed by oxidation, but the reaction proceeds successfully in either order. A wide range of functional groups and biologically relevant compounds are tolerated. The use of AcO15NH4 affords 15N-labeled compounds

    Dimensions of Anxiety, Age, and Gender: Assessing Dimensionality and Measurement Invariance of the State-Trait for Cognitive and Somatic Anxiety (STICSA) in an Italian Sample

    Get PDF
    The State–Trait Inventory for Cognitive and Somatic Anxiety (STICSA) is a widely used measure of state and trait anxiety that permits a specific assessment of cognitive and somatic anxiety. Previous research provided inconsistent findings about its factor structure in non-clinical samples (e.g., hierarchical or bi-factor structure). To date, no psychometric validation of the Italian version of the STICSA has been conducted. Our study aimed to determine the psychometric functioning of the Italian version of the STICSA, including its dimensionality, gender and age measurement equivalence, and convergent/divergent validity in a large sample of community-dwelling participants (N = 2,938; 55.9% female). Through confirmatory factor analysis, the multidimensional structure of both State and Trait STICSA scales, with each including Cognitive and Somatic dimensions, was supported. Factor structure invariance was tested and established at configural, metric, and scalar levels for males and females. Additionally, full factorial measurement invariance was supported for the State scale across young, middle age, and old adult groups whereas the Trait scale was partially invariant across age groups. The STICSA also showed good convergent validity with concurrent anxiety measures (State-Trait Anxiety Inventory and Beck Anxiety Inventory), and satisfactory internal discriminant validity with two depression measures (Teate Depression Inventory and Beck Depression Inventory-II). Results provided support for the multidimensionality of the STICSA, as well as the generalizability of the State and Trait scales as independent measures of Cognitive and Somatic symptomatology across gender in the general population. Implications for research and personality and clinical assessment are discussed

    A validation study of the Psychometric Properties of the Other As Shamer Scale-2

    External shame is associated to social and emotional difficulties, which are predictors of psychological disorders. The aim of the present study was to investigate the psychometric properties of the shorter Italian version of the Other As Shamer Scale (OAS-2), a measure of external shame. Confirmatory factor analysis was used in a sample of 612 (54.2% male) Italian undergraduate students. Evidence for this model provided support for the assumption that the one-factor model was similar across the gender groups. The Italian OAS-2 fully replicated the one-factor structure of the original OAS. Cronbach’s alpha index, as well as test–retest stability provided satisfactory results. The OAS-2 showed good convergent and divergent validity, being highly correlated with measures of internal shame, trait anxiety, and depression. The OAS-2 can be considered a useful instrument for measuring external shame when time constraints impede the use of the 18-item OAS. Implications of the results are discussed and recommendations for future work with the scale are made

    Resumen Objetivo: Comparar los resultados posoperatorios clínicos y radiográficos en dos grupos de pacientes: >55 años y ≤55 años, sometidos a una artroplastia total de tobillo de tercera generación. Materiales y Métodos: Se evaluó, en forma retrospectiva, a dos grupos de pacientes: ≤55 años (n = 13) y >55 años (n = 18), que fueron sometidos a una artroplastia total de tobillo de tercera generación. La edad promedio del grupo ≤55 años era 42.8 (DE 6.4) y la del grupo >55 años, 65.7 (DE 8.8). Resultados: El seguimiento promedio fue de 36 meses (RIC 25-60). La etiología era principalmente postraumática en ambos grupos. El puntaje promedio de la escala AOFAS al año de la cirugía fue 76,69 (RIC 58-89) en el grupo ≤55 años y 85,22 (RIC 67-100) en el grupo >55 años. No hubo diferencias estadísticamente significativas entre ambos grupos en los ángulos α, β y γ medidos en las radiografías con apoyo a los 2 meses y a los 2 años de la cirugía. Conclusiones: Nuestro estudio demostró que los resultados clínicos y radiográficos en pacientes más jóvenes serían comparables con los de pacientes más grandes en el seguimiento temprano. Se necesita un seguimiento a más largo plazo para determinar si el riesgo de revisión es más alto en los pacientes jóvenes, debido a la falla relacionada con el desgaste de la prótesis. Palabras clave: Tobillo; artroplastia; edad; artrosis de tobillo. Nivel de Evidencia: II

    Background and objectives: In patients with kidney failure due to IgA nephropathy, IgA deposits can recur in a subsequent kidney transplant. The incidence, effect, and risk factors of IgA nephropathy recurrence is unclear, because most studies have been single center and sample sizes are relatively small. Design, setting, participants, & measurements: We performed a multicenter, international, retrospective study to determine the incidence, risk factors, and treatment response of recurrent IgA nephropathy after kidney transplantation. Data were collected from all consecutive patients with biopsy-proven IgA nephropathy transplanted between 2005 and 2015, across 16 “The Post-Transplant Glomerular Disease” study centers in Europe, North America, and South America. Results: Out of 504 transplant recipients with IgA nephropathy, recurrent IgA deposits were identified by kidney biopsy in 82 patients; cumulative incidence of recurrence was 23% at 15 years (95% confidence interval, 14 to 34). Multivariable Cox regression revealed a higher risk for recurrence of IgA deposits in patients with a pre-emptive kidney transplant (hazard ratio, 3.45; 95% confidence interval, 1.31 to 9.17) and in patients with preformed donorspecific antibodies (hazardratio, 2.59; 95%confidence interval, 1.09 to 6.19).Afterkidneytransplantation,development of de novo donor-specific antibodies was associated with subsequent higher risk of recurrence of IgA nephropathy (hazard ratio, 6.65; 95% confidence interval, 3.33 to 13.27). Immunosuppressive regimen was not associated with recurrent IgA nephropathy in multivariable analysis, including steroid use. Graft loss was higher in patients with recurrence of IgA nephropathy compared with patients without (hazard ratio, 3.69; 95% confidence interval, 2.04 to 6.66), resulting in 32% (95% confidence interval, 50 to 82) graft loss at 8 years after diagnosis of recurrence. Conclusions: In our international cohort, cumulative risk of IgA nephropathy recurrence increased after transplant and was associated with a 3.7-fold greater risk of graft loss

    Integrative Processing of Touch and Affect in Social Perception: An fMRI Study

    Social perception commonly employs multiple sources of information. The present study aimed at investigating the integrative processing of affective social signals. Task-related and task-free functional magnetic resonance imaging was performed in 26 healthy adult participants during a social perception task concerning dynamic visual stimuli simultaneously depicting facial expressions of emotion and tactile sensations that could be either congruent or incongruent. Confounding effects due to affective valence, inhibitory top–down influences, cross-modal integration, and conflict processing were minimized. The results showed that the perception of congruent, compared to incongruent stimuli, elicited enhanced neural activity in a set of brain regions including left amygdala, bilateral posterior cingulate cortex (PCC), and left superior parietal cortex. These congruency effects did not differ as a function of emotion or sensation. A complementary task-related functional interaction analysis preliminarily suggested that amygdala activity depended on previous processing stages in fusiform gyrus and PCC. The findings provide support for the integrative processing of social information about others’ feelings from manifold bodily sources (sensory-affective information) in amygdala and PCC. Given that the congruent stimuli were also judged as being more self-related and more familiar in terms of personal experience in an independent sample of participants, we speculate that such integrative processing might be mediated by the linking of external stimuli with self-experience. Finally, the prediction of task-related responses in amygdala by intrinsic functional connectivity between amygdala and PCC during a task-free state implies a neuro-functional basis for an individual predisposition for the integrative processing of social stimulus content

    A many-analysts approach to the relation between religiosity and well-being

    The relation between religiosity and well-being is one of the most researched topics in the psychology of religion, yet the directionality and robustness of the effect remains debated. Here, we adopted a many-analysts approach to assess the robustness of this relation based on a new cross-cultural dataset (N = 10, 535 participants from 24 countries). We recruited 120 analysis teams to investigate (1) whether religious people self-report higher well-being, and (2) whether the relation between religiosity and self-reported well-being depends on perceived cultural norms of religion (i.e., whether it is considered normal and desirable to be religious in a given country). In a two-stage procedure, the teams first created an analysis plan and then executed their planned analysis on the data. For the first research question, all but 3 teams reported positive effect sizes with credible/confidence intervals excluding zero (median reported beta = 0.120). For the second research question, this was the case for 65% of the teams (median reported beta = 0.039). While most teams applied (multilevel) linear regression models, there was considerable variability in the choice of items used to construct the independent variables, the dependent variable, and the included covariates.</p
