Abstract
This paper is concerned with the numerical solution of multi‐dimensional convection dominated convection‐diffusion problems. These problems are characterized by a large parameter, K, multiplying the convection terms. The goal of this work is the development and analysis of effective preconditioners for iteratively solving the large system of linear equations arising from various finite element and finite difference discretizations with grid size h. When centered finite difference schemes and standard Galerkin finite element methods are used, h must be related to K by the stability constraint, Kh ≤ C0, where the constant C0 is sufficiently small. A class of preconditioners is developed that significantly reduces the condition number for large K and small h. Furthermore, these preconditioners are inexpensive to implement and well suited for parallel computation. It is shown that under suitable assumptions, the number of iterations remains bounded as h ↓0 with K fixed and, at worst, grows slowly as K ↓ ∞. Numerical results are presented illustrating the theory. It is also shown how to apply the theoretical results to more general convection‐diffusion problems and alternative discretizations (including streamline diffusion methods) that remain stable as Kh ↓ ∞.

Abstract
The focus of global training has primarily been on preparing employees to work effectively in other cultures, such as in expatriate training, acculturation training, and training for technology transfer. One issue that has been ignored is the implication of using training systems that are developed in a specific cultural context and then deployed globally. This chapter proposes a framework to show the influence of culture on one aspect of training effectiveness, the transfer of newly learned skills to the job. Specific relationships are proposed, using Baldwin and Ford’s (1988) transfer of training framework as a guide, and also by synthesizing findings from areas such as cross-cultural psychology, human resource management, education, and technology management.

Abstract
Purpose
The purpose of this paper is to bring attention to the issues of validity and subgroup differences of selection devices currently being used in the public sector.
Design/methodology/approach
An attempt is made to identify unfair hiring practices, particularly important within the public sector, as this area of employment is characterized by a unique set of circumstances. Among them, economic constraints, the social burden to ensure fair treatment among applicants and incumbents, and an increasingly higher expectation of quality service among customers in the public sector. This paper also explores the effectiveness of two strategies for reducing subgroup differences while maintaining or increasing criterion‐related validity.
Findings
The findings of this study are important and answer some central questions. First, g and job knowledge were the best individual predictors of overall performance criteria; second, the g, alternative, and full models all significantly predicted the performance criteria, with the alternative model predicting more variance than the g model; third, the alternative model had more incremental validity over the g model than the g model had over the alternative model; the alternative model also produced less subgroup differences for Black–White comparisons than the g model. The Native American‐White differences were larger for the alternative model compared to the g model, but these differences are considered small effects and were non‐significant in the statistical sense. The Hispanic‐White differences were also somewhat larger for the alternative model when compared to the g model; however, this result is probably unreliable due to a very small Hispanic sample size and is a small effect. Thus, the alternative model will predict performance well for similar public sector samples while producing generally smaller subgroup differences.
Originality/value
There is little extant published research examining the validity and ethnic group score differences of alternate predictors used in the US public sector and the current effort seeks to provide empirical evidence to fill this void.

Abstract
Purpose
The purpose of this paper is to examine the effectiveness of family-friendly programs at the workplace in the Indonesian higher education sector. The focus is the impact that these programs have on employees’ work family conflict.
Design/methodology/approach
A survey of academic and non-academic staff from 30 higher education institutions across Indonesia participated in the research. A total of 159 completed questionnaires from 109 academic and 50 from non-academic staff are reported and statistically analysed using SPSS.
Findings
Work and family experiences in Indonesia do not positively align with the findings reported in most academic literature pertaining to western societies where the use of family-friendly programs (i.e. flexible work options, specialized leave options and dependent care support) leads to a reduction in employees’ work family conflict. In fact, some of the programs were found to have the opposite effect in the Indonesian context.
Research limitations/implications
The design of family-friendly support has to take into account the context in which the policies will operates; these policies are not transferable across countries in terms of their effectiveness.
Originality/value
This is one of the first studies that has examined the operation and effectiveness of family-friendly support programs in an Indonesian context.

Abstract
This paper presents various approaches to studying cultures of different countries. The starting point is Hofstede's dimensions of cultural values as well as Hall's approach to high‐ and low‐context cultures. After that the interaction between culture and organizational behavior is discussed. A special attention to the impact of culture on motivation of employees, communication, conflict resolution and organizational changes is given. This article concludes with the presentation of some methods that can be applied to the training of managers on various cultures.

Abstract
Purpose
The purpose of this paper is to empirically investigate the possibility of financial crowding out in the long-term debt market in India taking the corporate bond market as a proxy.
Design/methodology/approach
The study follows a two-pronged approach. First, it tests the corporate bond market sensitivity to interest rate, along with other determinants like commercial bank credit and government securities size using the autoregressive distributed lag approach. These are considered instrumental in the development of a long-term debt market. Second, it tests if the interest rate changes are fiscal deficit (FD) induced using Granger causality framework.
Findings
It finds evidence of both the interest rate sensitivity of the corporate bond market and the interest rates to be FD induced, thereby empirically validating the possibility of financial crowding out in the Indian debt market segment.
Research limitations/implications
Based on the results, it seems that any deviation from the path of fiscal prudence can prove dear in the development of the corporate bond market. Also, the banking sector is overexposed to the risks it is not geared to handle, given by the serious asset-liability mismatches and contraction it leads in the market debt, like the corporate bond market. The government securities market could be further developed, which would provide a cue to corporate segment further and also a benchmark yield curve.
Originality/value
The study adds to the very limited literature on the corporate bond market in India, especially in the empirical domain and possibly is the first attempt to empirically explore the aspect of financial crowding out with reference to corporate bond market.

Abstract
The goal of this contribution is to shed light on the benefits for research in health care coming from the use of administrative data, especially in terms of measuring hospitals’ outcomes. The main approaches to health outcome evaluation are reviewed and the possible improvements deriving from the use of administrative data are highlighted. Administrative data may be an essential element in the process of gathering to the public true rankings of health care organizations, reducing the degree of asymmetric information that typically arises in health care. Patients will be more aware of the best institutions, which will induce most of them to demand to be admitted in them, taking into account the costs associated with distance and with the severity of the illness. This in turn may ask for a reorganization of the sector, closing some organizations and expanding others, having as final goal to improve the health status of the population, without income barriers. This is one of the first attempts to provide an overview of the advantages that administrative data may gather in health care.

Abstract
The training challenges facing organisations resulting from changes over the next several decades are described. These include a decreasing number of persons available for entry level positions including a growing proportion of undereducated young people. Also, jobs will become more complex as a result of technological developments and yet will require more interpersonal interaction between individuals who have different values and who come from different cultures. These changes will result in the need for training systems to maximise the potential of each individual, including basic skill and support programmes for unskilled young people who will need to perform more cognitively complex tasks. Training will also be necessary to help managers work with a more diverse workforce including helping individuals understand how to provide support for persons who have not traditionally been a part of their work organisation.

Abstract
Purpose
Although training is essential to continuous improvement, scant literature examines post-training facilitators for continuous improvement. The study aims to explore the relationship between training and continuous improvement, the mediating role of self-efficacy and the moderate role of training transfer climate.
Design/methodology/approach
This study utilizes the questionnaire survey of 455 Vietnamese employees to test the link between continuous improvement training and continuous improvement, the moderate role of the training transfer climate and the mediating role of self–efficacy.
Findings
Research results reveal that training positively influences continuous improvement. Furthermore, self-efficacy fully intervenes in the link between training and continuous improvement. Finally, the training transfer climate positively moderates this link.
Originality/value
Although the link between training and continuous improvement is suspicious, there is scant research on post-training facilitators of continuous improvement applications. To the best of the author's knowledge, this study is one of the first to explore the moderation role of transfer climate and the mediation role of self-efficacy in the relationship between training and continuous improvement.
