Active water loss management has become one of the primary interests of the water utilities in the world. Due to efforts of the IWA Task Force in the last decade, traditional approach of water loss expression in percentage of system input values has been proven to be misleading in may cases, and new way of performance measuring and benchmarking is proposed. This paper presents the basic principles of this methodology and results of the first step in attempt to approach Serbian water utilities performance according to new standards. Pirot water supply system is used as a case study to estimate pressure reducing impact on technical performance indictor values before introducing active leakage control.

Active water loss management has became one of the primary interest of the water utilities in the world. It can make significant saves and investments in new water resources capturing can be justified only if appropriate action is done to minimize loss from the water main. There is some level of unavoidable water loss from the water main. Traditional indicator of water loss, widely adopted in the world, was % of the system input value. It always sounds well to have water loss less than some prescribed value (for instance 10%). Due to efforts of IWA Task Force in the last decade, this approach has been proven to be misleading in may cases, and new way of performance measuring and benchmarking is proposed. This paper presents the basic principles of this methodology and the results of the first step in attempt to approach Serbian water mains to the new standards.

In 1999 and 2000, IWA Task Forces on Water Losses and Performance Indicators published their conclusions of over three years research, analysis and discussions. For the topics of Non-Revenue Water, Water Losses, Apparent Losses and Real Losses, these included:a recommended standard terminology, with definitions and procedures for assessing these components of the Annual Water Balance;recommended performance indicators for each of these components. This work represents a major step forward in defining the “best practice” approach to assessing and presenting components of Non-Revenue Water, for more rational comparisons of performance in diverse systems within a single organisation, within the same country, and between countries. The 21 members of the Water Services Association of Australia (WSAA) provide water and wastewater services to 12.9 million Australians. WSAA seeks to promote “best practice”, and act as a national focus for all interested parties. In February 2000 WSAA organised a national Workshop in Melbourne to discuss the IWA methodology. Arising from this Workshop, WSAA commissioned the production of customised Software and an Associated User Manual known as “Benchloss”, to promote and facilitate the application of the IWA recommended methodology throughout Australia. The paper will describe the development and application of “Benchloss” to date, with a comparison of Australian performance data against an International Data Set used by the Water Losses Task Force.

AbstractThis chapter presents a best practice framework for the operation of Big Data and Artificial Intelligence Centres of Excellence (BDAI CoE). The goal of the framework is to foster collaboration and share best practices among existing centres and support the establishment of new Centres of Excellence (CoEs) within Europe. The framework was developed following a phased design science process, starting from a literature review to create an initial framework which was enhanced with the findings of a multi-case study of existing successful CoEs. Each case study involved an in-depth analysis and a series of in-depth interviews with leadership personnel of existing CoEs.The resulting best practice framework models a CoE using open systems theory that comprises input (environment), transformation (CoE) and output (impact). The framework conceptualises the internal operation of the CoE as a set of high-level capabilities including strategy, governance, structure, funding, and people and culture. The core capabilities of the CoE include business development, collaboration, research support services, technical infrastructure, experimentation/demonstration platforms, Intellectual Property (IP) and data protection, education and public engagement, policy outreach, technology and knowledge transfer, and performance and impact assessment. In this chapter we describe the best practice framework for CoEs in big data and AI, including objectives, environment, strategic and operational capabilities, and impact. The chapter outlines how the framework can be used by a CoE to support its strategic direction and operational decisions over time, and how a new CoE can use it in the start-up phase. Based on the analysis of the case studies, the chapter explores the critical success factors of a CoE as defined by a survey of CoE managers. Finally, the chapter concludes with a summary.

This paper will challenge the traditional approach to providing bus transit, particularly on busy high-frequency arterial routes. It posits that conventional bus services are unable to meet contemporary urban sustainability and mobility challenges. Emerging approaches, such as the various forms of bus rapid transit, hold promise as ways to improve the perception of the bus and its usefulness to current transit riders and potential riders. This study uses a survey of best practice in bus transit improvements, as well as key informant interviews with professional service planners in the transit industry. Key findings are directed at the need for new and interdisciplinary ways of working, interdepartmental coordination, a high degree of active public engagement, and physical changes to bus transit systems. The findings informed a series of recommendations to help address the image and performance of bus transit in Toronto.

The personal assets framework suggests that dynamic elements of (a) personal engagement in activities, (b) quality social dynamics, and (c) appropriate settings will influence an athlete’s long-term outcomes of performance, personal development, and continued participation in sport. The aim of the present study was to conduct a case study of a Norwegian age-restricted team that was successful in promoting participation, performance, and positive development for individual participants and to investigate how the dynamic elements of activities, social dynamics, and settings have led to these long-term outcomes. The results indicated that the case is a best-practice example of successful attainment of personal development and long-term participation and performance through appropriate structure and application of the dynamic elements within the personal assets framework, including enjoyable peer-led play activities and quality practice, quality relationships with teammates and coaches, and access to facilities.

Abstract The control of water loss in distribution system has been highlighted in multiple discussions in the field of water and sanitation. Still, there are few scientific studies on this topic focussed on loss control performance in developing countries. With the intention to expand the limited scientific framework investigating the management of water losses in economic scarcity scenarios, the paper provides an overview of which practices directed to water loss control are being conducted in a Brazilian region. The data has been collected from 42 water utilities and shows there is a direct relationship between the utilities' performance and the number of water loss practices adopted. The divergences in the number of practices applied by the water utilities may be influenced by technical-operational, planning and management factors. The paper brings greater robustness to the loss management debates in regions with economic scarcity, being able to support the action of utilities operating in similar scenarios.

Purpose – This paper aims to evaluate a range of best practice knowledge management (KM) ideas used to manage knowledge resources. In total, four KM toolkits and 16 KM tools were tested over a five-year period (2008-2013), as part of a large-scale longitudinal change project. Each tool was assessed against an evaluative framework designed to test criticisms of KM: strategy, implementation and performance. The results provide empirical evidence about which KM tools work and which do not and why, and outcomes for practitioners, researchers and consultants. Design/methodology/approach – The case study organization participating in the study was selected because it was a knowledge-intensive organization, with an ageing workforce. An invitation and cover letter explaining the study were sent via email to all 150 engineering and technical staff at the case study organization. Therefore, the entire population was included in the study. Respondents were asked to attend training workshops. Following each workshop, respondents were asked to complete feedback in the form of learning journals and to be involved in work-place based trials of the KM tools. Both management and staff participated in the project. Findings – The results provide empirical evidence that KM can be used to manage knowledge resources. The highest rating toolkit was knowledge strategy, followed by knowledge measurement. The most value was created by using KM to introduce objectivity into future thinking (future capability requirements) and decisions when filling competency gaps (sourcing). The results tended to support criticism that KM is difficult to implement and identified the main barriers as participation located at the operational action research level, i.e. how do we make this work? Evidence that KM works was found in progress towards learning organization capacity and in practical outcomes. Research limitations/implications – The action research cycle and learning flows provide opportunities to examine barriers to KM implementation. The research also presents opportunities for further research to examine the findings in other organizational and industry settings, for example, the relationship between the KM toolkits and organizational change and performance, presents an important area for further research. Researchers might also consider some of the toolkits which rated poorly, e.g. knowledge creation (KC), and challenge these findings, perhaps selecting different KC tools for testing. The paper has limitations. It is based on a single case study organization, offset, to some degree, by the longitudinal nature of the empirical evidence. It is ambitious, and the findings may be controversial. However, the depth of the study and its findings provide rare longitudinal empirical evidence about KM, and the results should be useful for practitioners, researchers and consultants. Practical implications – There are many critics of KM. It has been described as overwhelmingly optimistic and managerial rhetoric; that its claims are false; and that many KM initiatives fail and, therefore, it does not create value for the firm, and its return on investment is unlikely. There is a shortage of empirical studies demonstrating an actual connection between KM and organizational performance. Despite widespread interest and growth in investment by practitioners and growth in research, KM needs validation to give people confidence in its value and some of the problems associated with implementation. This paper provides rare empirical evidence gathered from a five-year (2008-2013) large-scale longitudinal change project to address this gap. For practitioners, the research findings provide management with an evaluative framework to use when making decisions regarding KM. Originality/value – Much of the previous research on this topic looks at specific KM tools only, and often at one point in time. This study examined a wide range of best-practice KM tools as part of an integrated set of KM systems, launched at the same time and studied over five years. The study did not examine what the case study does in terms of KM. Instead, it deliberately introduced tools which were new to the case study organization. The results provide practical outcomes in terms of the effectiveness of KM when introduced to an organization as a system of integrated tools, and what happens in the five years that follow.

The growth of the event sector is underpinned by the demand of organizing a business event.  Thus, it leads to an increase in economic and social impact. However, the problems from the growth of this sector potentially results from the use of several event materials, transportation and infrastructure development.  Organizing a green event is seen as one of the strategies to reduce the environmental impact.  Therefore, the aim of this paper is to explore the issues involved throughout the process of greening an event by applying Mair and Jago Model.  Semi-structured interviews were conducted with event managers from six Malaysia business event companies that encourage green practices during their event.  Findings suggest that impact, initiative, support and performance motivates event organizers in organizing a green event.  It has also been found that knowledge, resources and behaviour are the barriers faced by event organizers throughout the process of organizing a green event.  Based on the findings it appears that two important factors have emerged from the data collection and analysis that showed a deviation from the Mair and Jago Model, namely “impact” for the motivation element and “support” for the barrier element.  The main limitation of this study was the scope of the study; as it only focuses on business events.  However, as the main purpose of this study is to explore the issues of organizing a green event, it has been found that there are other issues need to be explored in other contexts and geographical area.  Apart from this, as this is a case study, it can only replicate according to the circumstances of this case study. However, this study can be generalized in terms of the theory that has emerged from it.  It is suggested that further research should explore more issues in other contexts and geographical areas.
