The review has been done in a general sense, covering appraisal works by engineers, scientists, management experts, economists, sociologists and even historians. The outcome indicates that while there seems to be several works directly and/or indirectly assessing the performance of the refineries in a general sense, there is a dearth of such in the specific area of energy consumption. There also appears to be no single one appraising energy utilisation of all the refineries at the same time in the open literature. This is in spite of the fact that refining processes are energy intensive. Despite popularisation of exergy analysis as a veritable tool, the only energy utilisation appraisal within our reach which was carried out on just one of the refineries has not been done exergetically. However, the work still reveals, within the limitations of 1st Law energy analysis that the energy consumption patterns are below international benchmarks in the oil and gas industry. Some suggestions have also been offered to take care of the energy efficiency challenges in these refineries. These include plant to plant analyses of energy utilisation patterns in the four refineries, periodical determination of GHG emission levels in the refineries using current international best practices as benchmarks, use of exergy analysis to check avoidable energy wastage in the refining processes, shifting refinery fuelling pattern in favour of low carbon content fuels like natural gas and ensuring regular turnaround maintenance of the system.展开更多

These challenges might require flexible and reflective conversations with the employees. Aim: This study examines whether some performance appraisals (PAs) are more efficient and more effective than others. The study also shows how some performance appraisals are more suitable for home care and nursing homes in municipal health services. Methods: Two datasets are used: 1) a questionnaire was distributed to a representative sample of 600 health personnel in Norway;and 2) a questionnaire was distributed to a representative sample of 60 employees (test-group: 10 groups;control-group: 30 employees), in pre-test, post-test 1 and post-test 2. SPSS. Findings: Managers are the only ones who receive training in PA techniques (factory perspective). Nurses versus auxiliary nurses experience more frequent dyadic relationships and exchanges in PAs (family perspective). PAs for employees from nursing homes are fairer than those administered to home care employees (jungle perspective). In organizations closest to carnival perspectives, employees participating in group-PAs are more active in the conversations than employees who have individual conversations in PAs. Conclusions: Health personnel involved in PAs experience different effects of the conversational, and employees working as a member of a team in the organization need to experience a high quality of relationships (family), justice (jungle), and participation in group-conversation (carnival) during performance appraisals.展开更多
