Enabling organisational cultural change using systemic strategic human resource management - a longitudinal study

The paper reports on a longitudinal assessment of sustained organizational cultural change in the Australian Taxation Office. Results from a major action research change project are provided. A clear finding from this research is that the cultural change had been sustained through the systemic application of strategic human resource management.

Human resource management studies in mainland China : mainstream or alternative research?

Our paper presents a summary of the existing literature on human resource management (HRM) studies in mainland China published in the 25 leading international journals over the last 30 years. The aim is to take stock of what is known and what is yet to be known about HRM in China. We argue that what is known is comparative rather than definitive, with HRM in China treated as a subset of international HRM, rather than as a mainstream issue. With a quarter of the world’s population affected by an understanding of what constitutes better HRM in China, we call for a more inclusive, collaborative approach by researchers inside and outside China.

A critical review of human resource management studies (1978-2007) in the People's Republic of China

The study reviews the empirical studies on human resource management (HRM) practices in mainland China published in 26 leading international journals across the span of 30 years in the period 1978-2007. We intend to achieve three aims in this review: (1) to take an inventory of what have been done so far in the field of HRM studies in China; (2) to critically evaluate the development of Chinese HRM practices in the past 30 years; and (3) to identify research gaps for what needs to be done in the future. Along with this critical review, we also examine which research methods have been used in the empirical inquiries; where the research has been published; and who has made the most contribution in the field of Chinese HRM studies. We conclude that what is known is comparative rather than definitive, with HRM in China treated as a subset of international HRM, rather than as a mainstream issue. With a quarter of the world's population affected by an understanding of what constitutes better HRM in China, we call for a more inclusive, collaborative approach to further theorising and substantiating HRM studies by researchers inside and outside China.

Energy-efficient management of data center resources for cloud computing : a vision, architectural elements, and open challenges

Cloud computing is offering utility-oriented IT services to users worldwide. Based on a pay-as-you-go model, it enables hosting of pervasive applications from consumer, scientific, and business domains. However, data centers hosting Cloud applications consume huge amounts of energy, contributing to high operational costs and carbon footprints to the environment. Therefore, we need Green Cloud computing solutions that can not only save energy for the environment but also reduce operational costs. This paper presents vision, challenges, and architectural elements for energy-efficient management of Cloud computing environments. We focus on the development of dynamic resource provisioning and allocation algorithms that consider the synergy between various data center infrastructures (i.e., the hardware, power units, cooling and software), and holistically work to boost data center energy efficiency and performance. In particular, this paper proposes (a) architectural principles for energy-efficient management of Clouds; (b) energy-efficient resource allocation policies and scheduling algorithms considering quality-of-service expectations, and devices power usage characteristics; and (c) a novel software technology for energy-efficient management of Clouds. We have validated our approach by conducting a set of rigorous performance evaluation study using the CloudSim toolkit. The results demonstrate that Cloud computing model has immense potential as it offers significant performance gains as regards to response time and cost saving under dynamic workload scenarios.

Piecing together the puzzle of graduate employment : factors that shape the graduate work expectations of human resource management students

Providing graduates with a set of skills and attributes relevant to their future employment remains a key topic in both higher education policy and research. This paper reports findings from a pilot study of human resource management (HRM) students' perceptions of the graduate work experience. Specifically, it focuses on how these perceptions are shaped, driven by a concern for the uncertainty - and even fear - expressed by the study's participants in relation to their future workplace experiences. The influences of three key factors in shaping participants' expectations are discussed: the graduate recruitment experience, previous work experiences and 'graduate work folklore' from the stories of family and friends. With these influences not always providing students with a realistic picture of their future work experience, we conclude that educators need to improve the opportunities for practical experience and industry knowledge through work placements, stronger links with industry and increased exposure to the practicalities of work within the curriculum.

Direct method for optimal power management in hybrid electric vehicles

Hybrid electric vehicles are powered by an electric system and an internal combustion engine. The components of a hybrid electric vehicle need to be coordinated in an optimal manner to deliver the desired performance. This paper presents an approach based on direct method for optimal power management in hybrid electric vehicles with inequality constraints. The approach consists of reducing the optimal control problem to a set of algebraic equations by approximating the state variable which is the energy of electric storage, and the control variable which is the power of fuel consumption. This approximation uses orthogonal functions with unknown coefficients. In addition, the inequality constraints are converted to equal constraints. The advantage of the developed method is that its computational complexity is less than that of dynamic and non-linear programming approaches. Also, to use dynamic or non-linear programming, the problem should be discretized resulting in the loss of optimization accuracy. The propsed method, on the other hand, does not require the discretization of the problem producing more accurate results. An example is solved to demonstrate the accuracy of the proposed approach. The results of Haar wavelets, and Chebyshev and Legendre polynomials are presented and discussed. © 2011 The Korean Society of Automotive Engineers and Springer-Verlag Berlin Heidelberg.
