Leader-member exchange (LMX) and innovation climate: the role of LMX differentiation.
2013
AbstractLeader-member Exchange (LMX) theory has been shown to be one of the most compelling theories for understanding the effects of leadership on organizational behavior. This theory proposes that leaders establish differentiated relationships with each of their subordinates according to the exchanges produced between them. Recently, the concept of LMX differentiation has been introduced into the theory to extend research from the dyadic to the group level. The present paper uses a longitudinal design to analyze the moderator role of LMX differentiation in the relationship between mean LMX and innovation climate in a sample of 24 healthcare teams. The results showed no direct effects of m…
Effects of (un)employment on young couples’ health and life satisfaction
2012
This study investigated effects of employed and unemployed job status on health outcomes with questionnaires in 50 young couples. Analysis of variance revealed higher pessimism, higher stress levels, and lower life satisfaction in couples in which one partner was unemployed. These couples also exhibited more health risk behaviours compared to couples in which both partners were working. The dyadic analysis of data, using an actor-partner interdependence model, demonstrated strong actor and partner effects for male partner's job status. Being unemployed was significantly associated not only with male partner's life satisfaction but also with the life satisfaction of his female partner. In ad…
Jealousy at work: The role of rivals’ characteristics
2018
The present study examined rival characteristics that may evoke jealousy in the workplace, differences between men and women in this regard, and the relationship between jealousy responses and intrasexual competitiveness and social comparison orientation. Participants were 426 male and female employees. By means of a questionnaire, participants were presented with a jealousy-evoking scenario after which jealousy responses to 24 rival characteristics were assessed. Findings showed that a rival's social communal attributes evoked highest levels of jealousy, and that, compared to men, women reported more jealousy in response to a rival's physical attractiveness. Overall, as individuals had hig…
Epstein-Barr virus-associated acute pancreatitis: a clinical report and review of literature.
2022
Abstract Background Acute pancreatitis is a disorder of reversible inflammation of the pancreas. Only a few cases are related to infections and the most common pathogens are the viruses responsible for mumps, parotitis, and influenza. Epstein-Barr virus (EBV)-associated acute pancreatitis is a rare condition and it may occur in children and adults. Case presentation A 3-year-old female was admitted to the “G. Di Cristina” Children's Hospital in Palermo for vomiting and abdominal pain. Laboratory investigations revealed elevated amylase and lipase, with normal liver function tests. Abdominal ultrasound demonstrated an enlarged pancreas, with hypoechogenic areas; no biliary lithiasis was obse…
Post-transplant lymphoproliferative disorders after solid organ and hematopoietic stem cell transplantation.
2018
Post-transplant lymphoproliferative disorders (PTLD) are a rare complication after both solid organ (SOT) and allogeneic hematopoietic stem cell transplantation (allo-HSCT). In this single center retrospective study, we compared clinical, biological, and histological features, and outcomes of PTLD after both types of transplant. We identified 82 PTLD (61 after SOT and 21 after allo-HSCT). The presence of B symptoms, Waldeyer ring, spleen, central nervous system, and liver involvement, and advanced Ann-Arbor stage were more frequent in allo-HSCT recipients. PTLD had an earlier onset in allo-HSCT than in SOT cohort (4 vs. 64 months, p .0001). PTLD was EBV-positive in 100% of allo-HSCT, in co…
Clonal heterogeneity of thymic B cells from early-onset myasthenia gravis patients with antibodies against the acetylcholine receptor
2014
Myasthenia gravis (MG) with antibodies against the acetylcholine receptor (AChR-MG) is considered as a prototypic autoimmune disease. The thymus is important in the pathophysiology of the disease since thymus hyperplasia is a characteristic of early-onset AChR-MG and patients often improve after thymectomy. We hypothesized that thymic B cell and antibody repertoires of AChR-MG patients differ intrinsically from those of control individuals. Using immortalization with Epstein Barr Virus and Toll-like receptor 9 activation, we isolated and characterized monoclonal B cell lines from 5 MG patients and 8 controls. Only 2 of 570 immortalized B cell clones from MG patients produced antibodies agai…
Detection of human cytomegalovirus and Epstein-Barr Virus in symptomatic and asymptomatic apical periodontitis lesions by real-time PCR
2012
Objectives: Recent studies have investigated the occurrence of human cytomegalovirus and Epstein-Barr Virus in samples from apical periodontitis lesions and a role in the pathogenesis of this disease has been suggested. Because genotype distribution and seroprevalence of EBV and HCMV differ among populations, it is important to determine the presence of these viruses in endodontic periapical lesions of different populations. The aims of this study were to determine the presence of HCMV and EBV DNAs in samples from Turkish patients with symptomatic and asymptomatic apical periodontitis lesions using real-time polymerase chain reaction method and to evaluate their presence in both symptomatic…
Human herpesvirus type 8 DNA sequences in biological samples of HIV-positive and negative individuals in Sicily.
1997
Objective: To evaluate the circulation of a new human herpesvirus (HHV), HHV-8 or Kaposi's sarcoma (KS)-associated herpesvirus in a geographical area where a high incidence rate of classical KS was already present before the appearance of the AIDS epidemic. Design and methods: The study was carried out by analysing: (i) bioptic samples from classic, AIDS-associated KS, and controls; (ii) peripheral blood mononuclear cells (PBMC) from classic KS, HIV-positive subjects with and without KS and healthy HIV-negative individuals; (iii) semen samples from heterosexual HIV-positive and HIV-negative individuals affected or not by KS; and (iv) cervical swabs from HIV-negative healthy heterosexual fem…
Linking Organizational Justice to Burnout: Are Men and Women Different?
2005
This study tested the links from organizational justice with burnout and the moderating role of sex in these relationships. A total of 279 contact employees (149 men and 130 women) were surveyed in 59 hotels. A questionnaire was used to measure distributive, procedural, and interactional justice as well as employees' burnout (exhaustion, cynicism, and efficacy). Hierarchical regression models, calculated to test the hypothesized effects, indicated the predominance of procedural justice over distributive and interpersonal with regard to the direct relationships between organizational justice and burnout. Analysis also showed that links from interactional justice with exhaustion and cynicism…
From being alone to being the only one: Neuroticism is associated with an egocentric shift in an alone context
2019
Objective This research presents evidence for an egocentric shift occurring among individuals high in Neuroticism by the mere thought-and actual state-of being alone. Method Four experiments and one experience sampling study (N = 719). In the experiments, Neuroticism was measured, and participants were randomly primed to adopt either an alone or a "with others" social context mind-set. The experiments measured different expressions of egocentrism. Study 1 measured perspective-taking, Study 2a was focused on social value orientation, Study 2b measured money allocation in a dictator game, and Study 3 measured self-reported and behavioral interpersonal trust. Trust was also the focus of Study …
