Importers should take more responsibilities for carbon emissions embodied in trade,and China should take a certain responsibility for unreasonable energy dissipations too.展开更多

Methods: Two hundred and fifteen members of competitive sports clubs responded to scales measuring coach characteristics of justice, benevolence, integrity, and competence; athlete's trust in the coach; commitment to coach; willingness to cooperate; and perceived performance. Results: Confirmatory factor analysis of data supported the measurement model. Perceptions of a coach's justice (β = 0.19, p 〈 0.05), benevolence (β = 0.32, p 〈 0.05), integrity (β= 0.14, p 〈 0.05), and competence (β = 0.29, p 〈 0.05) each had a significant effect on athletes' trust, and they cumulatively accounted for 61% of the variance in trust. The structural equation modeling showed that trust had direct effects on commitment to coach (β = 0.77, p 〈 0.01), willingness to cooperate (β= 0.79, p 〈 0.01 ), and perceived performance (β = 0.51, p 〈 0.01),. The hypothesized mediating effects of commitment to coach and willingness to cooperate were not supported. The model explained 26% of the variance in perceived performance. Conclusion: As trust in coach influences commitment to coach, willingness to cooperate, and perceived performance, coaches need to take effort to bolster their athletes' trust by being just and benevolent, and enhancing their integrity and competence.展开更多

Many enterprises are unwilling to make a commitment to social responsibility, even consider that fulfilling their social responsibility goes against the improvement of enterprise performance. However, with the development of social economy and the improvement of living standards of the people, the performance of corporate social responsibility play a more and more important role. The paper defines the content included in corporate social responsibility, makes theoretical analysis on the relation between corporate social responsibility and enterprise financial ability, and makes the relativity and regression analysis on the relation between enterprise social responsibility and enterprise financial ability.展开更多

The same open loop control system is observed in different operating systems with and without multitasking environment. The Data Acquisition (DAQ, PLC-812PG) card is used as a hardware interface. From the experiment, it could be seen that in the non real time operating system (Windows), the delay of the control system is larger than the Soft Real Time OS (Linux). Further, the authors observed the same control system under Hard Real Time OS (RT-Linux). At this point, the experiment showed that the real time error (jitter) is minimum in RT-Linux OS than the both of the previous OS. It is because the RT-Linux OS kernel can set the priority level and the control system was given the highest priority. The same experiment was observed under multitasking environment and the comparison of delay was similar to the preceding evaluation.展开更多

This paper examines directors' perceptions of the three main roles: monitoring, service, and strategic, which provide tools for critically understanding how the board adds the value in moving the organization towards more CSR practices. The stakeholder theory is used to distinguish the influence of the three main roles on the adoption of CSR practices. Primary data were collected for this research by conducting structured questionnaires with a sample of 461 directors from Saudi listed companies for study purpose. The results show that an appropriate mix of directors' roles and the development of sound board monitoring and service roles are the most crucial determinants of CSR adoption in Saudi listed companies. As the extant corporate governance and CSR literatures do not provide a clear perspective with contradictory outcomes about board roles in influencing CSR practices, the originality of this research is its contribution by evaluating the directors' perceptions of developing a direct relationship between the board roles and the adoption of CSR practices. Furthermore, the use of the stakeholder theory provides additional insights into identifying the most influential board role factors enhancing stakeholders' expectations of CSR practices.展开更多

Initially, the promises and perils of artificial intelligence are brought forward in pointing out (1) that it remains an open question whether moral decision making, understood as situated ethical judgement, is computationally tractable, and (2) that the kind of artificial intelligence, which would be required to cause ethical reasoning, would imply a system capable of operating as an independent reasoner in novel contexts (sec. 2). In continuation thereof, issues of responsibility are discussed (sec. 3 and 3.1) and it is claimed that unacceptable responsibility gaps may occur since unpredictability would presumably follow full system autonomy. These circumstances call for a strong precautionary principle, in the form of a preemptive ban.展开更多

The multi-dimension evaluation metrics include functional and nonfunctional properties and corresponding weights. The continuous measurement values and the Markov chain mechanism are adopted to compute the trust value and detect the malicious behaviors. The current evaluation has larger influence factor on the next transaction behavior. A trust model is implemented with web service which consists of publication, filtrating, calculating and storage center. It is easily extended and the user only defines each property and its weights according to specific requirements, then the trust values are got. In order to conveniently manage and avoid the dead-lock, some constraint rules are proposed. The results show that the method based on multi-dimension can reflect objectively the dynamic change of trust values.展开更多

Despite the wide distribution of air pollutant sources, the concentration of indoor pollutants may be the dominant risk factor in relation to personal exposure, as most people spend an average of 87% and 6% of their time within enclosed rooms and vehicles, respectively. Under these circumstances, wind driven rotating ventilators, which use natural energy and are cheap to manufacture, install and maintain, can become very effective non-polluting means of alleviating the problems within enclosed spaces. The author has been pioneering design and performance studies of environment friendly products such as the rooftop ventilator for over a decade at the University of New South Wales in Australia. The purpose of this paper is to detail the basic working principles of this ventilator and the series of detailed experimental and numerical investigations that has been performed in the optimization of the rooftop ventilator in terms of performance with higher air mass extraction rate and improved safety in operation has been achieved. Findings from these studies have been incorporated in the design of ventilators that are now commercially produced and marketed throughout the world by CSR Edmonds Pry Ltd of Australia. The conduct and outcomes of these works form the basis of this keynote paper.展开更多
