Diagnostic value of PET/MR with DWI for burkitt lymphoma
No full text18F-FDG-PET/MR images, including DWI, of a 46-year-old male admitted to the Emergency Room of our tertiary center, who was suffering from diplopia, left orbital pain, and a headache for two weeks, demonstrated multiple hepatic nodules, a pancreatic mass, and skeletal metastases, in addition to thrombosis of the left cavernous sinus, thickening of the small intestine, and a large hepatic lesion identified at head and neck MR and whole-body CT, respectively. Hepatic and bone marrow biopsies revealed the diagnosis of Burkitt lymphoma. After four cycles of rituximab, cyclophosphamide, doxorubicin, vincristine, methotrexate/ifosfamide, etoposide, and high dose cytarabine (R-CODOX-M/IVAC), a complete metabolic response occurred
The impact of role stressors on workplace bullying in both victims and perpetrators, controlling for personal vulnerability factors: A longitudinal analysis
No full textBy drawing on the concept of hindrance stressors and using a longitudinal research design, we investigated whether role conflict and role ambiguity predicted being a victim of bullying twelve
months later, over and above personal vulnerability. With a parallel analysis we also investigated whether the same role stressors predicted the enactment of bullying. The sample consisted of 234
employees of a National Health Service agency in Italy. The results indicated that role conflict positively affected being bullied and bullying enactment, with personal vulnerability (reporting a
doctor’s diagnosis of depression at baseline) affecting only the first of the two outcomes. However, some evidence also emerged of reciprocal relationships between role stressors and bullying
A longitudinal analysis of the relationship between role stressors and negative social climate at work
No full textAccording to the work environment hypothesis of bullying, poor working conditions lead to bullying through the development of a negative social climate at work which fuels interpersonal conflict, of which bullying is an extreme example. In the present study, by adopting a full panel longitudinal design, we contribute to research in this area by testing whether role stressors – which are considered the main potential antecedents of bullying – predicted negative social climate at work (e.g. “At my work, the interpersonal climate is strained”) one year later once personal vulnerability factors have also been controlled for. Data were collected from a sample of 215 employees of the Italian national healthcare system by using an anonymous questionnaire. Structural equation modelling analysis showed that role stressors had a positive lagged effect on negative social climate at work. Personal vulnerability, which was measured in terms of mental distress, had also a lagged effect on negative social climate. The results indicate that role stressors are implicated in the creation (or intensification) of negative social climate at work, suggesting that the path from role stressors to bullying which is proposed by the work environment hypothesis may indeed be mediated by the escalation of interpersonal conflicts
A Tikhonov Theorem for McKean–Vlasov Two-Scale Systems and a New Application to Mean Field Optimal Control Problems
No full textWe provide a new version of the Tikhonov theorem for both two-scale forward systems and also two-scale forward-backward systems of stochastic differential equations, which also covers the McKean–Vlasov case. Differently from what is usually done in the literature, we prove a type of convergence for the "fast" variable, which allows the limiting process to be discontinuous. This is relevant for the second part of the paper, where we present a new application of this theory to the approximation of the solution of mean field control problems. Towards this aim, we construct a two-scale system whose "fast" component converges to the optimal control process, while the "slow" component converges to the optimal state process. The interest in such a procedure is that it allows one to approximate the solution of the control problem, avoiding the usual step of the minimization of the Hamiltonian
Work environmental and individual difference factors as antecedents of bullying at work: A longitudinal investigation
No full textAssessment of structural-functional integration impact on connectivity abnormalities in glioma patients
No full textMotivation: Brain networks glioma’s disruption was often explored through separate examinations of structural and functional connectivity. However, there were limited efforts in glioma research to investigate the interplay between structure-function and how this connection might influence our comprehension.
Goal(s): Can integrating structural and functional connectivity aid understanding the alterations’ neurobiological foundation in brain networks caused by glioma?
Approach: The study design involves standard diffusion MR and rs-fMRI preprocessing, statistical methods including Pearson and Spearman correlation and Euclidean distance computation.
Results: This study underscores the significance of examining structure-function integration, where both microstructure and function play crucial roles in relation to white matter integrity.
Impact: Glioma, the primary brain tumor, affects both structural and functional connectivity. Understanding alterations in structure-function integration and connection with single-modalities, may be of highest significance for a more comprehensive explanation of compensatory mechanisms induced by glioma and its clinical progression
Exploring the relationship between workaholism and workplace aggressive behavior: The role of job-related emotion
No full textMost research on workaholism has been devoted to the refinement of the construct and to the study of its psychological health correlates. In the present study, we contribute to a better understanding of the interpersonal and organizational consequences of workaholism by investigating its relationship with workplace aggressive behaviour. Drawing on well-established models of workplace aggression, we hypothesised that workaholism would be related to aggressive behaviour
over and above working conditions (e.g. interpersonal conflict), which are widely known for their potential to trigger aggressive behaviour. Furthermore, we also hypothesised that job-related affective states (specifically high-arousal negative affective states) would mediate the workaholism-aggressive behaviour relationship. We tested the hypotheses in two different samples of employees (N = 574, and N = 282) by using hierarchical regression and bootstrap multiple mediation analyses. Results were in line with predictions in both samples, suggesting that workaholism is an important factor as far as workplace aggression is concerned
