This study aims to enhance an enterprise’s private cloud services by optimally determining the ownership of cloud computing resources and responsibility for maintenance and operations. The core objective is to identify the most cost-effective private cloud deployment model at the intersection of technology and business considerations.

This study evaluates three ownership and responsibility models, each encompassing decisions related to candidate data center locations, resource provisioning, and demand placements. Drawing from the cloud computing literature, these models are referred to as deployment models. The research formulates a private cloud deployment model selection problem and introduces an established Lagrangian-relaxation-based optimization approach, combined with a novel greedy relieving-pooling heuristic, to facilitate model selection.

This study identifies the optimal deployment model for a representative instance using real test-bed data from the US, demonstrating the private cloud deployment model selection problem. Various numerical examples are analyzed to explore the influence of environmental parameters. Generally, the virtual PC model is optimal for low demand arrival rates and resource requirements, while the on-premises PC model is preferable for higher values of these parameters. Additionally, the virtual PC model is found to be optimal when enroute latency coefficients are large.

This study contributes to the literature by formulating an optimization problem that integrates performance, financial, and assurance metrics for enterprises. The introduction of a solution approach enables enterprises to make informed decisions regarding ownership and responsibility design. The study effectively bridges the gap between academic research and industry demands from a business perspective.

The purpose of this paper was first to find out whether the negative relationship between board size and future firm risk persists in China while contemplating all sorts of endogeneity. Second, the authors have investigated the role of large shareholders in influencing the managerial decisions concerning future firm risk via board size. Finally, the authors examined whether the moderating role of large shareholders is any different in state-owned enterprises (SOEs) and non-state-owned enterprises (NSOEs) in China.

The sample included all the A-listed firms listed on the Shanghai and the Shenzhen stock exchanges over a sample period from 2008 to 2013. The authors used fixed effects regression and the generalized method of moments (GMM) to test the three hypotheses.

The authors found that board size is negatively associated with future firm risk when measured as volatility in future stock prices and future cash flows. Second, large shareholders directly influence managerial decisions about future firm risk, irrespective of board size. Third, the moderating role of ownership concentration is insignificant in both SOEs and NSOEs.

To the best of the authors’ knowledge, this is the first study which has analyzed the role of large shareholders in the relationship between board size and future firm risk. This study provides valuable insights, particularly in the context of a developing country, into the role played by large shareholders in influencing managerial decisions concerning future firm risk.

The purpose of this paper is to examine empirically whether corporate governance mechanisms have an effect on income‐smoothing behavior in the People's Republic of China.

The sample comprises 1,358 companies listed in the Shanghai Stock Exchange and the Shenzhen Stock Market during the period 1999 to 2006. By comparing the variability of income to the variability of sales, an income smoother can be identified if income is less variable than sales.

The authors' empirical results show that income smoothing is more severe when the state is the controlling shareholder of the Chinese listed firm. Firms with more independent directors are more likely to engage in income smoothing. The governance mechanisms such as board of directors, supervisory board, audit committee, external auditors, and shareholders' participation are not effective in curtailing income smoothing in China.

For Chinese firms and especially government‐linked enterprises, the way in which they present themselves may be significant, since the image they present to potential strategic partners may be marred by suspicions of income smoothing.

The paper presents the current development of China's corporate governance system and indicates that agency conflicts between controlling shareholders and minority investors account for a significant portion of earnings management in China.

This paper aims to explore the pathways of carbon transfer in 200 US corporations along with the motivations that drive such transfers. The particular focus is on each firm’s embeddedness in the global value chain (GVC) and the influence of environmental law, operational costs and corporate social responsibility (CSR). The insights gleaned bridge a gap in the literature surrounding GVCs and corporate carbon transfer.

The methodology comprised a two-step research approach. First, the authors used a two-sided fixed regression to analyse the relationship between each firm’s embeddedness in the GVC and its carbon transfers. The sample consisted of 217 US firms. Next, the authors examined the influence of environmental law, operational costs and CSR on carbon transfers using a quantitative comparison analysis. These results were interpreted through the theoretical frameworks of the GVC and legitimacy theory.

The empirical results indicate positive relationships between carbon transfers and GVC embeddedness in terms of both a firm’s position and its degree. From the quantitative comparison, the authors find that the pressure of environmental law and operational costs motivate these transfers through the value chain. Furthermore, CSR does not help to mitigate transfers.

The findings offer insights for policymakers, industry and academia to understand that, with globalised production and greater value creation, transferring carbon to different parts of the GVC – largely to developing countries – will only become more common. The underdeveloped nature of environmental technology in these countries means that global emissions will likely rise instead of fall, further exacerbating global warming. Transferring carbon is not conducive to a sustainable global economy. Hence, firms should be closely regulated and given economic incentives to reduce emissions, not simply shunt them off to the developing world.

Carbon transfer is a major obstacle to effectively reducing carbon emissions. The responsibilities of carbon transfer via GVCs are difficult to define despite firms being a major consideration in such transfers. Understanding how and why corporations engage in carbon transfers can facilitate global cooperation among communities. This knowledge could pave the way to establishing a global carbon transfer monitoring network aimed at preventing corporate carbon transfer and, instead, encouraging emissions reduction.

This study extends the literature by investigating carbon transfers and the GVC at the firm level. The authors used two-step research approach including panel data and quantitative comparison analysis to address this important question. The authors are the primary study to explore the motivation and pathways by which firms transfer carbon through the GVC.

Despite the many advantages this type of equipment offers, there are still some major drawbacks. Linear cutting machine (LCM) cannot accurately simulate the true rock-cutting process as 1. it does not account for the circular path along which tunnel boring machine (TBM) disk cutters cut the tunnel face, 2. it does not accurately model the position of a disk cutter on the cutterhead, 3. it cannot perfectly replicate the rotational speed of a TBM. To enhance the knowledge of these issues and in order to mimic the real rock-cutting process, a new lab testing equipment was developed by Hyundai Engineering and Construction.

A new testing machine called rotary cutting machine (RCM) is designed to simulate the excavation process of hard-rock TBMs and includes features such as TBM cutterhead, RPM simulation, constant normal force mode and constant penetration rate mode. Two sets of tests were conducted on Hwandeung granite using different disk cutter sizes to analyze the cutting forces in various excavation modes. The results are analyzed using statistical analysis and dimensional analysis. A new model is generated using dimensional analysis, and its results are compared against the results of actual cases.

The effectiveness of the new RCM test was demonstrated in its ability to apply various modes of excavation. Initial analysis of chip size revealed that the thickness of the chips is largely dependent on the cutter spacing. Tests with varying RPM showed that an increase in RPM results in an increase in the normal force and rolling force. The cutting coefficient (CC) demonstrated a linear correlation with penetration. The optimal specific energy is achieved at an S/p ratio of around 15. However, a slightly lower S/p ratio can also be used in the design if the cutter specifications permit. A dimensional analysis was utilized to develop a new RCM model based on the results from approximately 1200 tests. The model's applicability was demonstrated through a comparison of TBM penetration data from 26 tunnel projects globally. Results indicated that the predicted penetration rates by the RCM test model were in good agreement with actual rates for the majority of cases. However, further investigation is necessary for softer rock types, which will be conducted in the future using concrete blocks.

The originality of the research lies in the development of Hyundai Engineering and Construction’s advanced full-scale laboratory rotary cutting machine (RCM), which accurately replicates the excavation process of hard-rock tunnel boring machines (TBMs). The study provides valuable insights into cutting forces, chip size, specific energy, RPM and excavation modes, enhancing understanding and decision-making in hard-rock excavation processes. The research also presents a new RCM model validated against TBM penetration data, demonstrating its practical applicability and predictive accuracy.

This research provides valuable insights into the specific experiences of postgraduate students at UT, offering actionable recommendations for educators and policymakers to support thesis writing in distance learning contexts.

Corporate governance (CG) is a mechanism for directing, administering and controlling organisations. CG has become a vital component in driving efficient operation of state-owned enterprises (SOEs). The purpose of this paper is to examine the relationship between CG practices and the performance of Thai SOEs.

This research is quantitative in nature; data were collected through a questionnaire, which was distributed to a sample of 1,140 respondents from 38 Thai SOEs. Structural equation modelling was used for data analysis.

The results indicate that the board of directors has a direct negative influence on the performance of Thai SOEs. However, management systems play a significant role in mediating the relationship between boards of directors and the performance of Thai SOEs. Additionally, corporate governance practices should be implemented not only at the board-of-director level but also at all levels of operation throughout the organisation.

To develop effective boards of directors, SOEs should be pushed to develop the appropriate strategic management systems (i.e. risk management, internal controls, internal audits, human resource management and information technology). These systems allow boards of directors to access and use important information that will help guide the business process, which leads to performance improvement in SOEs.

This empirical study investigates the relationships between CG practices and the performance of SOEs in the context of developing countries.

The purpose of this paper is to investigate the link between board structure and performance of public companies in Russia – an emerging market with unique institutional background and a variability of corporate governance (CG) practices across its companies.

Panel data analysis was applied on a sample of 207 Russian companies that frequently traded in the Russian Trading System during the period 2007-2011, in order to test hypotheses on the relationships between board size, board independence, gender diversity, presence of board committees and financial performance, as measured by Tobin’s Q.

The results show a positive relationship between Tobin’s Q and the board’s gender diversity. The analysis demonstrates that smaller and bigger boards are associated with a greater Tobin’s Q value.

The findings provide additional evidence of how board structure is related to its effectiveness and corporate performance in countries with concentrated ownership, highly variable CG practices and a lack of proper implementation of corporate law and governance codes. The paper contributes to the existing empirical evidence on the advantages of small and large-sized boards and on gender diversity, and is the first investigating the relationship between Russian companies’ board committees and market-based performance. The results regarding board independence and committees suggest that these mechanisms are still not widely recognized for their role in CG and company performance in Russia.

This paper aims to examine how the governance structure incorporates corporate social responsibility (CSR) into corporate behaviour in the perspective of the external environment within emerging countries.

The paper reviews the various CSR legislations enacted in the global context and in particular reference to the Indian Companies Act 2013.

The embedded relationship between CSR and corporate governance (CG) is an outcome of extensive dimensions such as ownership structure, stakeholder approach and other external environmental factors such as the government regulations and legislation, legal enforcement and corporate disclosure culture.

The enactment of the Companies Act 2013 in India has infused a new direction for the corporations in implementing CSR and CG practices. This paper throws light on the coverage of the Companies Act 2013 and various challenges faced by the companies in the applicability of the CSR and CG framework in the Indian context.

This paper aims to investigate whether a powerful chief executive officer (CEO) impacts corporate risk taking in the distinctive institutional and market setting of China? Second, in case such relationship exists, the paper further aims to investigate whether the presence of large shareholders affects it, and finally, whether this effect of large shareholders varies in state-owned enterprises (SOEs) and non-state-owned enterprises (NSOEs).

The authors have used a sample of 1,502 Chinese firms listed on Shanghai and Shenzhen stock exchanges. Sample period is 2008-2013. Besides conventional fixed-effect regression, dynamic panel data estimation (generalized method of moments) is applied to address the potential endogeneity.

The results show that CEO power is negatively related with corporate risk taking in two risk proxies, i.e. total risk and idiosyncratic risk. Second, the presence of large shareholders significantly affects this relationship, but does not change the primary negative relationship between CEO power and corporate risk taking. Finally, the results show that the relationship between CEO power and corporate risk taking is different in SOEs and NSOEs. The findings of this paper contend the organizational and behavioral theory viewpoint that individual decisions are more extreme.

This study provides useful implication for policymakers and suggests that while evaluating CEO’s performance, institutional and market settings should be considered.

This study provides new insights on the impact of CEO power on corporate risk taking under the two distinctive features in a developing country, i.e. presence of large shareholders and state-owned enterprises.
