Massive obstacles are frequently presented by the colossal amounts of acoustic information and the incredibly quick processing times. This results in the need for applications and methodologies that are capable of automatically analyzing these contents. These technologies can be applied in automatic contentanalysis and emergency response systems. Breaks in manual communication usually occur in emergencies leading to accidents and equipment damage. The audio signal does a good job by sending a signal underground, which warrants action from an emergency management team at the surface. This paper, therefore, seeks to design and simulate an audio signal alerting and automatic control system using Unity Pro XL to substitute manual communication of emergencies and manual control of equipment. Sound data were trained using the neural network technique of machine learning. The metrics used are Fast Fourier transform magnitude, zero crossing rate, root mean square, and percentage error. Sounds were detected with an error of approximately 17%;thus, the system can detect sounds with an accuracy of 83%. With more data training, the system can detect sounds with minimal or no error. The paper, therefore, has critical policy implications about communication, safety, and health for underground mine.展开更多

In addition, this article examines whether CSR mediates the relationship between TMT process and firm performance. The sample consists of 203 hotels from the tourism and hospitality industry in the southeast China. TMT processes assessed are communication and cohesion. Results indicate that (1) corporate social responsibility is positively related to firm performance, (2) top management team process (communication and cohesion) is positively related to corporate social responsibility, and (3) corporate social responsibility fully mediates the relationship between top management team process and firm performance. Results highlight upper echelons mechanisms that underpin the TMT process-firm performance relationship. This study contributes to understanding how TMT process affects firm performance both directly and indirectly, through strategic CSR.展开更多

文摘This article aims to explore how top management team (TMT) process affects strategic corporate social responsibility (CSR), and in turn, how strategic CSR influences firm performance. In addition, this article examines whether CSR mediates the relationship between TMT process and firm performance. The sample consists of 203 hotels from the tourism and hospitality industry in the southeast China. TMT processes assessed are communication and cohesion. Results indicate that (1) corporate social responsibility is positively related to firm performance, (2) top management team process (communication and cohesion) is positively related to corporate social responsibility, and (3) corporate social responsibility fully mediates the relationship between top management team process and firm performance. Results highlight upper echelons mechanisms that underpin the TMT process-firm performance relationship. This study contributes to understanding how TMT process affects firm performance both directly and indirectly, through strategic CSR.
