The Additive Value of Positive Psychological Capital in Predicting Work Attitudes and Behaviors
Conventional wisdom over the years and recent research findings have supported the importance of positivity in the workplace. However, to date, empirical analysis has not demonstrated potential added value of recently emerging positive state-like constructs such as psychological capital over the more established positive traits in predicting work attitudes and behaviors. This study of a sample of employees (N=336) from a broad cross section of organizations and jobs found that their state-like psychological capital is positively related to desired extra-role organizational citizenship behaviors (OCBs) and negatively with undesired organizational cynicism, intentions to quit and counterproductive workplace behaviors. Except for individual OCBs, their psychological capital also predicted unique variance in the same attitudinal and behavioral outcomes beyond their demographics, core self-evaluation, and personality traits, and person-organization fit and person-job fit. The article concludes with implications these findings have for future research and practical application
Group-Level Organizational Citizenship Behavior in the Education System: A Scale Reconstruction and Validation
Secretion of five extracellular enzymes by strains of chromoblastomycosis agents Secreção de cinco enzimas extracelulares por amostras de agentes da cromoblastomicose
The gelatinase, urease, lipase, phospholipase and DNase activities of 11 chromoblastomycosis agents constituted by strains of Fonsecaea pedrosoi, F. compacta, Phialophora verrucosa, Cladosporium carrionii, Cladophialophora bantiana and Exophiala jeanselmei were analyzed and compared. All strains presented urease, gelatinase and lipase activity. Phospholipase activity was detected only on five of six strains of F. pedrosoi. DNase activity was not detected on the strains studied. Our results indicate that only phospholipase production, induced by egg yolk substrate, was useful for the differentiation of the taxonomically related species studied, based on their enzymatic profile.<br>As atividades gelatinase, urease, lipase, fosfolipase e DNase de 11 agentes da cromoblastomicose constituĂdos por amostras de Fonsecaea pedrosoi, F. compacta, Phialophora verrucosa, Cladosporium carrionii, Cladophialophora bantiana e Exophiala jeanselmei foram analisadas e comparadas. Todas as amostras apresentaram atividade urease, gelatinase e lipase. A atividade fosfolipase foi detectada apenas em cinco das seis amostras de F. pedrosoi. A atividade DNase nĂŁo foi detectada nas amostras estudadas. Os resultados indicam que para a diferenciação entre espĂ©cies taxonomicamente relacionadas estudadas, baseado no seu perfil enzimático, apenas a produção de fosfolipase, induzida pelo substrato com gema de ovo, foi Ăştil
