HR and IT capabilities and complementarities in knowledge-intensive services

The main premise of this article is that human resources (HR) and information technologies (IT) are central rather than support functions in knowledge-intensive services. By building management capabilities in both HR and IT, knowledge-intensive services can transform their business processes that, in turn, enable them to provide exemplary services to the customers. Our arguments are grounded in the three related theoretical frameworks of the resource-based view, organizational capabilities, and the theory of complementarities. We suggest that the research and practice in HR and IT fields may have to focus on HR and IT capabilities rather than HR practices or IT investments as the sources of sustainable competitive advantage since capabilities better fit the definition of a ‘resource’ than HR practices or IT investments. Further, organizational capabilities in both HR and IT may enable knowledge-intensive services to transcend the inherent tradeoff between cost and responsiveness. We also discuss the role of HR and IT in knowledge management.

Performance assessment and optimisation of a large information system by combined customer relationship management and resilience engineering: a mathematical programming approach

ISs and ITs play a critical role in large complex gas corporations. Many factors such as human, organisational and environmental factors affect IS in an organisation. Therefore, investigating ISs success is considered to be a complex problem. Also, because of the competitive business environment and the high amount of information flow in organisations, new issues like resilient ISs and successful customer relationship management (CRM) have emerged. A resilient IS will provide sustainable delivery of information to internal and external customers. This paper presents an integrated approach to enhance and optimise the performance of each component of a large IS based on CRM and resilience engineering (RE) in a gas company. The enhancement of the performance can help ISs to perform business tasks efficiently. The data are collected from standard questionnaires. It is then analysed by data envelopment analysis by selecting the optimal mathematical programming approach. The selected model is validated and verified by principle component analysis method. Finally, CRM and RE factors are identified as influential factors through sensitivity analysis for this particular case study. To the best of our knowledge, this is the first study for performance assessment and optimisation of large IS by combined RE and CRM.

Jobs requiring a capacity for engineering systems thinking (CEST): Selection using an interest inventory

Systems thinking is recognized as a critical ability for engineers who take a leading role in complex projects. Identifying those engineers with better systems‐thinking capabilities is critical in many projects and organizations and enables organizations and project managers to select and place the most suitable engineers for jobs requiring a Capacity for Engineering Systems Thinking (CEST). However, up until now, no tool aimed at assessing individuals' capacity for engineering systems thinking has ever been developed. This paper presents principles for developing an interest questionnaire aimed at selecting engineers for jobs requiring systems thinking as well as preliminary results regarding the tool's reliability and validity.

Computing systemic risk using multiple behavioral and keystone networks: The emergence of a crisis in primate societies and banks

What do the behavior of monkeys in captivity and the financial system have in common? The nodes in such social systems relate to each other through multiple and keystone networks, not just one network. Each network in the system has its own topology, and the interactions among the system’s networks change over time. In such systems, the lead into a crisis appears to be characterized by a decoupling of the networks from the keystone network. This decoupling can also be seen in the crumbling of the keystone’s power structure toward a more horizontal hierarchy. This paper develops nonparametric methods for describing the joint model of the latent architecture of interconnected networks in order to describe this process of decoupling, and hence provide an early warning system of an impending crisis.     

Validating the Construct of Public Service Motivation in For-profit Organizations: A preliminary study

Delineating the theoretical link between individuals’ discretion and motivations in the private sector and their public service behaviours in Chinese society, this study explored public service motivation (PSM) in for-profit organizations. A survey of 348 employees from three engineering consulting organizations in China validated the construct of PSM in for-profit organizations. Besides the positive correlation between conscientiousness and PSM, the current study demonstrated that a positive correlation exists between PSM and community citizenship behaviour (CCB) with love of money (LOM) as a marginal moderator: the positive relationship between PSM and CCB is marginally stronger when LOM is higher, vice versa.

Epidemics,labour markets and unemployment: the impact of SARS on human resource management in the Hong Kong service sector

This article examines the links between epidemics and their economic consequences, specifically in terms of their impacts on labour markets and jobs. To exemplify the above, we examine the effects of SARS (Severe Acute Respiratory Syndrome) on the Hong Kong economy, its labour market and its level of employment and unemployment. The article hypothesizes that the greatest impact would be on human resource management (HRM) in the service industries and on particular sub-sectors, such as the hotel sector. It concludes that the dramatic demand and supply ‘shocks’ significantly affected both the demand for and the supply of labour in the sector, with discernible HRM consequences.     

The pricing accuracy of alternative equity valuation models: Scandinavian evidence

In many decision contexts, there is a need for benchmark equity valuations, based on simplified modeling and publicly available information. Prior research on U.S. data however shows that the accuracy of such valuation models can be low and sensitive to the choice of model specifications and value driver predictions. In this paper, we test the applicability and pricing accuracy of three fundamental valuation (dividend discount, residual income, and abnormal earnings growth) models, all based on forecasts of company dividends, earnings, and/or equity book values. Extending prior research, we apply these models to Scandinavian firms with accounting data from the period 2005–2014, explicitly testing two approaches for the prediction of the value drivers—exogenously forecasted numbers versus projected historical numbers. Given access to the forecasted value drivers, the dividend discount model comes out as the most accurate valuation model. In particular, this holds in a comparison between the most parsimonious model specifications. The residual income valuation model generates the best pricing accuracy given the prediction of value drivers based on historical financial numbers. Notably, we observe pricing errors that in general are lower than what has been reported in prior U.S.‐based research for the dividend discount and the residual income valuation models. The pricing accuracy of the abnormal earnings growth models is surprisingly weak in the Scandinavian setting. However, these models improve somewhat after a couple of complexity adjustments, in particular with value driver predictions based on the projected history setting.
