Explaining the use of performance information by public managers: Do task-related factors matter?
Full text linkOrganizational factors have frequently shown a significant influence on the use of performance information by public managers, but the study of task-related factors has been neglected. Combining insights from public administration, organizational studies, and a behavioural approach, this article investigates whether some task characteristics influence the use of performance information by public managers. Drawing on an e-mail survey on managers working in Italian medium-size municipalities, an empirical analysis was developed. Findings show that task analysability and task variability directly affect performance information use by public managers. Task interdependence shows an indirect effect on performance information use through its availability

No full textIn this study, the effects of bicarbonate addition on growth and pigment contents of the unicellular microalga Nannochloropsis oculata, were evaluated. N. oculata represents an interesting source of biomolecules widely used for food supplements and nutraceuticals. The bicarbonate was supplemented to microalgae cultures at concentrations of 0, 6, 18, 30, 42 and 60 mM. The cultures supplemented with salt at highest concentrations (42 and 60 mM) showed a significant increase in algal growth, demonstrated by the optical density spread. The intracellular content of pigments such as chlorophyll a and total carotenoids reached the highest values in cells from cultures supplied with bicarbonate. In fact, concentrations of bicarbonate from 30 to 60 mM strongly improved, for a short period of only 72 h, the cellular levels of chlorophylls and carotenoids. These are interesting pigments with commercial applications. The utilization of bicarbonate could represent an interesting sustainable opportunity to improve microalgae cultivation for cellular growth and pigment contents
