Abstract
In recent years, many organisations responsible for economic infrastructure have developed asset management systems to improve the financial and service performance of their facilities. Asset management is an integrated approach to improving the ability of an irrigation system to deliver water at a defined level of service in the most cost‐effective manner. This paper describes how the analytic hierarchy process (AHP) is applied to identify priorities for asset renewals in the La Khe irrigation scheme in North Vietnam. The AHP methodology was coupled with the expected maximum utility (EMU) to evaluate renewal priorities of assets grouped by types and by location within the hydraulic system.

Abstract
This paper describes the application of heuristic techniques for designing gravity wastewater collection systems. Designing sewer networks can be a time‐consuming task that is largely based on trial and error where suitable pipe diameters and slopes combinations for all pipelines between manholes must be identified. Since there is a large range of possible slopes, diameters and roughness coefficients of pipes, only a small number of combinations of these parameters are usually analyzed in traditional design processes. Identifying a minimum cost design is an important issue when constructing sewer networks. In this paper, genetic algorithms and tabu search techniques are implemented to solve this difficult optimization problem. An adaptive rule and a dynamic search strategy were developed to assist the search procedures find better solutions.

Abstract
Purpose
In this study, a finite element model of a box-girder bridge along with the railway sub-track system is developed to predict the static behavior due to different combinations of the Indian railway system and free vibration responses resulting in different natural frequencies and their corresponding mode shapes.
Design/methodology/approach
The modeling and evaluation of the bridge and sub-track system were performed using non-closed form finite element method (FEM)-based ANSYS software.
Findings
From the analysis, the worst possible cases of deformation and stress due to different static load combinations were determined in the static analysis, while different natural frequencies were determined in the free vibrational analysis that can be used for further analysis because of the dynamic effect of the train vehicle.
Research limitations/implications
The scope of the current investigation is confined to the structure's static and free vibration analysis. However, this study will help the designers obtain relevant information for further analysis of the dynamic behavior of the bridge model.
Originality/value
In static analysis, the maximum deformation of the bridge deck was found to be 10.70E-03m due to load combination 5, whereas the maximum natural frequency for free vibration analysis is found to be 4.7626 Hz.

Abstract
It has often been said that a great part of the strength of Aslib lies in the fact that it brings together those whose experience has been gained in many widely differing fields but who have a common interest in the means by which information may be collected and disseminated to the greatest advantage. Lists of its members have, therefore, a more than ordinary value since they present, in miniature, a cross‐section of institutions and individuals who share this special interest.

Abstract
The librarian and researcher have to be able to uncover specific articles in their areas of interest. This Bibliography is designed to help. Volume IV, like Volume III, contains features to help the reader to retrieve relevant literature from MCB University Press' considerable output. Each entry within has been indexed according to author(s) and the Fifth Edition of the SCIMP/SCAMP Thesaurus. The latter thus provides a full subject index to facilitate rapid retrieval. Each article or book is assigned its own unique number and this is used in both the subject and author index. This Volume indexes 29 journals indicating the depth, coverage and expansion of MCB's portfolio.

Abstract
The study investigated the relationship of career instrumental and expressive intra‐organizational network resources with extrinsic and intrinsic career success and with the Big‐Five of personality in a sample of 264 white‐collar workers. Total network resources were associated with extrinsic and intrinsic career success above the contribution of human capital, demographics and mentoring received. And instrumental network resources contributed more strongly than expressive network resources to extrinsic career success. Furthermore, instrumental network resources emerged as important for intrinsic evaluations of hierarchical and interpersonal career success while expressive network resources emerged as important for intrinsic evaluations of job and interpersonal career success. There was limited support for the influence of personality on the accumulation of network resources. As hypothesized, conscientiousness was negatively associated with instrumental network resources; however, extra‐version, openness and agreeableness failed to make significant contributions to network resources over and above the contribution of human capital and demographics. The implications of the findings for individual career tactics and for organizational practices are discussed and the limitations of the study are considered along with directions for future research.

Abstract
Research has shown that, when employees’ work-family conflict levels are reduced, performance in the workplace can increase. How to reduce these levels, however, is a complex task. The purpose of this empirical study was to investigate the differences in work-family conflict between full-time worksite employees and full-time teleworking employees (individuals who teleworked from home at least two days per week). Employees (n = 308) in seven for-profit companies in Minnesota were sampled and surveyed using a slightly revised version of the Carlson and Kacmar (2000) work-family conflict scale. The findings indicate that teleworkers had lower levels of overall work-family conflict as well as most of the other work-family conflict variables explored (i.e., strain-based, time-based, work interference with family, family interference with work)

Abstract
Purpose
This study aims to examine the outcomes of consumer perceptions of event social responsibility (ESR) for a sponsored community event and its sponsor portfolio (i.e. group of sponsoring companies). It integrates a new antecedent and new moderators of ESR with extant findings to provide a comprehensive model that is theoretically grounded in social identity theory, congruency theory and image and affect transfer.
Design/methodology/approach
The authors test the theoretical framework via a field study of attendees (n = 879) at a sponsored, large-scale sporting event that provided ESR through health and wellness education and activities. A field study is especially appropriate because of the experiential nature of sponsored events and ESR.
Findings
Fan identification with the sport is an antecedent of ESR, and motivation to attend the event’s supporting activities moderates the relationship between fan identification and ESR. High event-sponsor fit strengthens the relationship between ESR and word-of-mouth and between ESR and sponsor patronage.
Research limitations/implications
This study illuminates the role of ESR as a key driver of outcomes for events and for their sponsor portfolio. Future research should investigate ESR in contexts other than sport and use longitudinal data that include actual purchases. It should further examine the construct of sponsor portfolio because so many events have multiple sponsors
Practical implications
Event sponsorship offers an attractive platform for brands to demonstrate good corporate citizenship; therefore, marketers should consider ESR as a key criterion when selecting events to sponsor. Marketers should sponsor events with high event-sponsor portfolio fit to enhance the outcomes related to ESR for both sponsors and events. This research generally underscores the importance of creating auxiliary, interactive experiences for event attendees.
Social implications
ESR entails that events should contribute or give back to the local communities and organizations in a charitable way to both help give back socially and to maximize success as measured by electronic word-of-mouth (eWOM) and sponsor patronage toward brands sponsoring the event.
Originality/value
This research identifies a new antecedent and new moderators of ESR and integrates them with extant findings to create a comprehensive, theoretically grounded model. It investigates outcomes for both the event and its sponsor portfolio, in contrast to the scholarship that tends to focus on the (title) sponsor.

Abstract
Looks at the 2000 Employment Research Unit Annual Conference held at the University of Cardiff in Wales on 6/7 September 2000. Spotlights the 76 or so presentations within and shows that these are in many, differing, areas across management research from: retail finance; precarious jobs and decisions; methodological lessons from feminism; call centre experience and disability discrimination. These and all points east and west are covered and laid out in a simple, abstract style, including, where applicable, references, endnotes and bibliography in an easy‐to‐follow manner. Summarizes each paper and also gives conclusions where needed, in a comfortable modern format.
