Performance assessment is essential to effectively evaluate and monitor the activity of water utilities, support decision making, and encourage continuous improvement. Performance assessment systems (PAS), covering several service objectives and criteria, have been successfully applied in water supply and wastewater systems. Tailored approaches focusing on the assessment of the energy use and efficiency in wastewater systems are still limited. This paper aims at the development and demonstration of a comprehensive PAS for energy efficiency, tailored for wastewater systems, incorporating criteria related to energy consumption, operation and maintenance (O&M) costs, and environmental impacts, such as untreated discharges and greenhouse gases emissions, among others. Management and control of excessive or undue inflows to these systems is specifically addressed by several novel criteria and metrics. The proposed PAS should be adapted by each utility to be aligned with the objectives of the organisation and with the implemented asset management strategy. The proposed approach and the resulting consolidated PAS are thoroughly described. Results from the application of the PAS to several Portuguese utilities are discussed. This PAS aims at contributing to a reliable and replicable process to assess energy efficiency in wastewater systems and to encourage a more rational energy management.

Abstract Optimizing the efficiency of urban water systems is a growing concern for water utilities worldwide. Wastewater treatment plants (WWTP) are crucial in maintaining water quality and resource recovery in a world facing growing challenges such as climate change, water-energy-food nexus and the increase of legal requirements and users' expectations. Thus, adopting a performance assessment system (PAS) is of the utmost importance to assess operating conditions and to identify critical aspects of the WWTP which can negatively affect its effectiveness, efficiency and reliability. This paper presents the global and operational performance assessment of an urban WWTP and identifies improvement measures. The WWTP presented a good performance in terms of effectiveness and reliability. Nevertheless, in terms of efficiency, relevant improvement opportunities were identified, specifically in the sludge treatment phase and in terms of energy management. PAS was proven to be successful in the identification and prioritization of rehabilitation needs in a systematic way which will continuously improve the efficiency and effectiveness of the WWTP as well as to support asset management decisions regarding their upgrade and retrofit.

Abstract. In its first 100 years, the Rorschach has been heralded as a valuable method for investigating disturbances in thought organization and reasoning. It has survived periods of intense scrutiny and criticism, as contemporary researchers continued to demonstrate the empirical validity of the Rorschach as a measure of disordered thinking ( Mihura et al., 2013 ). It is fitting to mark the centenary of Rorschach’s “experiment” by summarizing contemporary contributions of the Rorschach Performance Assessment System (R-PAS) and reviewing the empirical and conceptual bases for using the inkblots to assess disordered thinking and communication.

Scholarly Attention

Recent evidence of the adoption of technologically mediated systems of knowledge management as part of the trend to accountability in the Institutions of Higher Education around the world has been widely disseminated in World Bank and UNESCO reports, and the effects of assessment driven accountability on preparation programs extensively debated in scholarly communities. Less scholarly attention has been paid to the institutional effects of the technology enhanced performance assessment evidentiary demands on university programs undergoing review by national accrediting bodies. The lack of scholarly attention is addressed by presenting a case study examining the institutional dynamics of accreditation review experienced by faculty in one department that offered graduate programs leading to certification for education leaders. Drawing from institutional analysis (Scott, 2008a, 2008b) a conceptual framework is established in a discussion of conditions of enactment of the regulative, normative and cognitive facets of the institutional dynamics evident in the implementation ecology of accountability systems. The case study analysis outlines four phases of development of the essential elements of a web-based assessment system, and describes the questions raised by faculty about performance evidence, the assessment of that evidence, and the nature of measures of program outcome effectiveness. Classic theories of organizations fail to fully explain the concerns and questions that were raised by faculty. In contrast, Engeström’s (1999, 2001, 2008) theory of expansive learning grounded in Cultural Historical Activity Theory (CHAT) provides insights into faculty responses to questions raised by the criteria for program review established by the accrediting body. Artifacts of expansive learning evident in the development of a performance assessment system can be viewed as reflecting institutionalization of regulative, normative, and cognitive dimensions of the emergent evaluative state of leadership preparation around the world. Implications are suggested for understanding the development of information technology (IT) enhanced knowledge management systems (KMS).
