Moreover, the static energy-efficient power control （SEPC） algorithm is proposed in static scenario to maximize the capacity of secondary users （SUs） and to reduce the power consumption according to the interference from PU to SU. Furthermore, based on the analysis of PU＇s dynamic feature with Markov chain and SEPC algorithm,the dynamic energy-efficient power control （DEPC） algorithm is proposed taking into account the probability of detection and false alarm caused by sensing errors. Extensive simulation results show that the performance of the proposed algorithms is significantly improved compared with the existing algorithm.展开更多

Unlike the previous researches, this study attempts to empirically examine the role of surplus free cash flow （SFCF） as a moderator in the relationship with the new requirements of Malaysian code on corporate governance （MCCG）. By using the estimated generalized least square （EGLS） upon a sample of Malaysian firms, the results show that firms with an independent chairman experience persistent earnings numbers. The results also demonstrate that the current earnings of finns with small boards and independent audit committee members are more likely to persist in the future, when SFCF is high. However, in contradiction to the authors＇ expectation is the significant, but negative and interactive effect of current earnings and audit committee competence on earnings persistence. The findings, though disappointing, suggest investors to consider both the governance structure and free cash flow （FCF） agency problem when evaluating the sustainability of firms＇ earnings. They also call for more independent directors, effective meetings, and more competent audit committee members.展开更多

The need to develop new management theories, tools, and techniques to compete with the ＂Gang of Four＂ （Amazon, Apple, Google, and Facebook） is also discussed in some depth as well as providing a critique of traditional models/strategic approaches and more recent theories. This is considered to be an important area of research because as a new class of Internet company emerges, incumbent firms in traditional industries will need to know how to prepare for the new challenges that face them.展开更多

In Malaysia, the recently introduced Green Book program aims to strengthen the corporate governance among the government-linked companies （GLCs）, in view of their significant contributions to the national socio-economic development. The Green Book initiative, launched in 2005, contains, among other things, a provision to create a high-performing board. Performance of GLCs, therefore, is likely to scale better heights with the modification of the constitution of the boards. The present paper aims to examine the association between the selected corporate governance attributes and performance of GLCs in 2010, approximately five years since the implementation of the transformation program. The regression analysis reveals that none of the selected corporate governance indicators has significantly impacted the performance of GLCs. The findings serve as a wake-up call to the authorities to appraise the effectiveness of the transformation program in enhancing the performance of GLCs.展开更多

Crucial for which is the success of the Securities Commission＇s ＂Corporate Governance Blueprint 2011＂ and ＂Capital Market Master Plan 2＂ designed to provide a business environment which attracts investment and talent. Somewhat overlooked in these otherwise robust policy shifts has been a critical critique of the definition, nature, and purpose of corporate governance itself. Recognizing this oversight, Tan Sri Muhyiddin Yassin, Malaysia＇s Deputy Prime Minister, has directed that the definition of corporate governance be rejuvenated for the 21st century. This paper looks to answer that challenge by recommending the following transformational definition for corporate governance： ＂the proactive implementation of accountable ethical processes, procedures, and policies that inspires innovative aspirational economic activity to produce sustainable wealth and prosperity for shareholders, stakeholders, and society＂.展开更多

Factors of motivation, such as monetary reward, recognition, affiliation, job security, and work environment that influence account executives motivation have been highlighted. Quantitative method was used in this study with the help of questionnaire data collection. The questionnaires were distributed among one of the telecommunication company account executives. The study found that there are significant differences in motivation level between gender, age, year of service, salary, and workplace of account executives. Monetary reward, job security, and work environment were found as the significant drivers to motivate account executives. The study also found that improvement on public recognition and affiliation factors failed to bring positive impact towards account executives motivation. Consistently, the findings can conclude that there is a relationship between account executives and sales commission plan that can lead to increase in motivation. Despite the positive result, the study can suggest the company to improve its bottom-line where sales commission plan program needs further revision in accordance with account executives factors of motivation.展开更多

Such systems can undergo major disturbances that have serious consequences. Individually, these disturbances can be attributed to specific causes, such as lightning strikes, ice storms, equipment failure, shorts resulting from untrimmed trees, excessive customer demand, or human errors. In the paper, the human errors from electrical transmission networks of Romanian Power Grid Company over period of 10 years are analyzed. It is hoped that obtained results will provide engineers a better understanding so they can cater to the needs of the human operators when to implement new interfaces for network monitoring tasks, not for the other technical objectives.展开更多

The study finds that for companies which experienced financial distress, the audit reports are not similar, despite all companies are similarly troubled financially. Companies receive either a disclaimer or an emphasis of matter （EOM） report. The study finds that which of the two reports is given is associated with three variables： current-year operating loss, shareholders＇ deficit, and default status, implying that audit reports do convey information that financial distress is not of the same level and severity among PN 17 companies.展开更多

We are witnessing a regional disparity regarding the volume of foreign investments in this area, which is due to the difference of attractiveness of host countries economy. The attractiveness of these economies is conditioned, in its turn, by the importance of economic factors and the quality of existing infrastructures, which is at their turn facing an increasing complexity of technology. Business relocation of foreign investors is influenced also by the institutional environment, because foreign investors hope to capitalize on the collateral effects offered by the investment environment in the host country, such as research laboratories and existing infrastructure, without neglecting the benefits of a highly qualified workforce at reduced costs, some geopolitical advantages, etc.. After EU accession, the attractiveness index of business environment in Romania has increased from （-59%） in 2005 to 66% （2008）, and Romania was considered among the most attractive economies in Central and Eastern Europe, along with Russia where the attractiveness index increased from 63% （2007） to 72% （2008） and Ukraine which has seen an increase in the attractiveness index of the business environment from 56% （2007） to 67% （2008）. This paper aims to highlight the positive effects induced by international business companies in assessing technological absorption capacity of the Romanian economy and to provide economic analysis of the ＂cause-effect＂ link between the attractiveness of the Romanian economy-governance--the intake of foreign investment straight to the active processing export of Romania under the impact of the overall effects of international financial crisis.展开更多
