The estimation of queue length and delays in queues that are oversaturated for some part of a study period is of substantial importance in a range of traffic engineering applications. Whiting’s co-ordinate transformation has provided the basis for several approaches to this. We analyse this approach and present an explicit form for the derivative of queue length with respect to time, which we then use to establish various properties. We also report the results of numerical comparisons with exact formulae for certain special cases and show that these offer little or no advantage over the co-ordinate transformation approximations and can be computationally impractical in study periods of moderate duration.

Data sets were compiled from the MHIDAS data bank for incidents where there had been five or more fatalities, ten or more injuries, 50 evacuations, or US$1 million damage. The data were converted to magnitudes on the Bradford Disaster Scale and analysed using maximum likelihood. Parameters determined from the estimation procedures were compared for compatibility between themselves and the results of analyses using other data.

Increased annual precipitation and more frequent episodes with heavy precipitation are expected in Norway due to climate change. The purpose of this paper is to use two case studies to investigate effects of precipitation on the amounts of faecal indicator bacteria and parasitic protozoa (Cryptosporidium and Giardia) loaded to surface waters from catchment areas exposed to different faecal sources.

In the first case study, the loads of faecal indicator bacteria and Cryptosporidium and Giardia, were investigated in relation to precipitation in a stream from a small valley where cattle and sheep are grazed. In the second case study, historical data (monthly values from 2004‐2009) regarding faecal coliforms and water flow in five tributaries (urban and rural) of a lake used as a drinking water source, were used for calculating loads of faecal indicator bacteria. These loads were evaluated in relation to historical data on precipitation. Additional sampling during/after rainfall, including analysis of samples for Cryptosporidium and Giardia, was performed.

The study visualises how heavy rainfall may increase the load of faecal microorganisms and potential pathogens in Norwegian water sources.

This study provides supplementary information about microbial contamination (including by parasites) of Norwegian surface waters during or after rainfall. This is useful input for decision making regarding protection of vulnerable water sources and for risk assessments. Data are also provided for evaluation of water treatment needs for Norwegian municipalities and waterworks responsible for providing safe drinking water under future climatic conditions.

How to make university‐based executive programmes more effective by making certain design and delivery changes is discussed. It is argued that the programmes can be made more effective by being more practical, learner centred and developmental. Three areas are focused on: programme design, the training, development and role of the faculty, and the role of the sponsoring companies. These changes are governed by principles and practices of adult learning that are used as core strategies in the programmes to develop general managers who will be able to lead the modern information‐based organisation.

Posits that every enterprise must institutionalize its workplace learning systems and opportunities in such a way that it radiates what it has already achieved and from this moves on to realize its full potential – in short, the enterprise itself is the key. Examines in successive chapters: the individual manager and questioning insights (Q); the major systems which the enterprise uses to capture and structure its learning; a SWOT analysis of the enterprise′s total learning; action learning, its contribution to the achievement of enterprise growth, and the role of programmed knowledge (P); the Enterprise School of Management (ESM) as a phoenix of enlightenment and effectiveness rising from the ashes of traditional, less effective management training initiatives; and, finally, the practical realization of the action learning dream, as evidenced by emerging examples of successful and profitable implementation worldwide. Concludes with a selection of pertinent abstracts.

Interest in management development is mushrooming. The number of articles which address different aspects of it are likewise increasing apace. This has heightened the need for a broad‐based review which will pull the material together, give shape to it, evaluate it and draw out its implications. In this, the first of a two‐part article, this task is commenced.

Describes the efforts of the owner/directors of a private limited company to put into place a succession strategy. Considers three major themes: second generation entrepreneurs/management succession; action learning as a human resource development strategy and philosophy; and the learning organization. Concludes that people (and organizations) “learn” best from the priorities of the business, once they have been identified, and that organizational learning is really based on institutionalization of what has been learned – requisite learning.

This study aims to examine the day‐to‐day problems that managers face in trying to be effective and the resources and solutions that they access as a means of dealing with these challenges.

This research summarizes the results of 185 interviews with managers employed at a broad range of levels and employers.

The managers were concerned with managing employee conflict, addressing employee performance and attitude issues, and finding employees who do not present these problems. Helpful advice came from the people around them rather than from print sources. The managers were unlikely to view consultants as sources of help.

In identifying relevant teaching from a managerial perspective, this study suggests that curriculum designers pay more attention to teamwork and generic skill sets. Future research should examine the implications of pedagogical approaches on the practice of management, employ a random sample of a larger group of managers in order to cross‐validate this study's results, and, given that there may be a disparity between managers' perceptions and practice, a follow‐up study is needed that examines day‐to‐day managerial practice.

This study proposes that management researchers and teachers may need to do a “Mintzbergian turn” and examine how much time they spend directly addressing the issues that are important to managers on a day‐to‐day basis. This study suggests that management educators may need to move beyond presenting managerial issues as a series of “topics” to be recalled by students at a later date. Rather, there is a need to consider what issues real managers grapple with and how they go about doing so.

This study's open‐ended research approach permitted the examination of what was most important to managers from their perspective.

Limited published research has examined the role of leaders and managers in building learning capability and learning organizations. It is speculated that leaders and managers will assume roles such as facilitators of learning, coaches, and teachers. However, these roles and the micro‐behaviors manifested in them remain an area that has not been fully explored. This article reports specific findings from a qualitative critical incident study that was designed to investigate the multiple ways exemplary managers facilitate their employees’ learning in organizations considered to be learning organizations. Thirteen behavior sets emerged from this research that help to define the role of facilitator of learning. Implications for management development are discussed and areas for future research are identified.

The purpose of this paper is to examine the implications of work-life-balance (WLB) challenges for Nigerian female medical doctors. This study focusses on Nigeria, which its peculiar socio-cultural, institutional and professional realities constitute WLB as well as social sustainability (SS) challenge for female medical doctors.

Relying on qualitative, interpretivist approach and informed by institutional theory, this study explores how Nigeria’s institutional environment and workplace realities engender WLB challenges, which consequently impact SS for female doctors. In total, 43 semi-structured interviews and focus group session involving eight participants were utilised for empirical analysis.

The study reveals that factors such as work pressure, cultural expectations, unsupportive relationships, challenging work environment, gender role challenges, lack of voice/participation, and high stress level moderate the ability of female medical doctors to manage WLB and SS. It also identifies that socio-cultural and institutional demands on women show that these challenges, while common to female physicians in other countries, are different and more intense in Nigeria because of their unique professional, socio-cultural and institutional frameworks.

The implications of the WLB and SS requires scholarship to deepen as well as extend knowledge on contextual disparities in understanding these concepts from developing countries perspective, which is understudied.

This study offers fresh insights into the WLB and SS concepts from the non-western context, such as Nigeria, highlighting the previously understudied challenges of WLB and SS and their implications for female doctors.
