These researches are conducted in four language streams, namely, Chinese, Spanish, Korean and Japanese. It will talk about problems identified in all these four language streams, with Chinese as the focus. Although according to various definitions, translation competence includes several parts, which are all required for a professional translator; this essay covers mainly the linguistic competence with tense and aspect issue as the main point. Meanwhile, some major causes of mistakes will be identified, such as interference of mother tongue, lack of second language proficiency. In the end, some possible ways for improvement are presented for reaching what are needed for a professional translator.展开更多

Design/methodology/approach: A survey was conducted. Two hundred questionnaires were distributed to students of 9 universities at different levels in Tianjin, China; 171 were returned. Descriptive statistics were performed to analyze the data. Findings: The results indicate that Chinese college students usually ignored the negative influence of fake or pornographic or other indecent information, invasion of privacy and theft of confidential information, and violation of intellectual property rights. Although they could distinguish to some extent between ethical and unethical behavior, they were not concerned about others’ unethical behavior on the Web. The study also indicates that gender, age, academic major and expertise in using computers were related to the students’ awareness of ethical issues relating to the use of the Internet and their attitude to these issues.Research limitations: The sample is limited to the universities in Tianjin. A larger sample, which includes colleges and universities in the western or other developing areas in China, is needed to further validate our findings.Practical implications: The study helps educators and academic librarians better understand Chinese college students’ awareness of and attitude to ethical issues surrounding the use of the Internet. It thus could assist them in the improvement of information ethics education for college students.Originality/value: This study was one of the first empirical studies to investigate the factors influencing Chinese college students’ awareness of and attitude to Internet ethical issues.展开更多

In order to reduce the environmental problems thereby creating a sustainable environment, there is an urgent need for new models, algorithms, methodologies, platforms, tools, devices, and systems. Hence, green computing and communications solutions should be effectively and practically designed with more renewable energy, higher energy efficiency, lower greenhouse gas emission, and environmental friendly materials.展开更多

Because it lies between the radio frequencies and infrared wavelengths, the terahertz electromagnetic region was thought to be promising for practical applications （300 micrometers wavelength corresponds to 1 THz frequency）, but it suffered from very high attenuation through the atmosphere （above 1 dB/meter）, and was found to be difficult to generate, modulate, and detect. On the other hand, many non-polar dielectric materials are transparent to THz waves,展开更多

These researches are conducted in four language streams, namely, Chinese, Spanish, Korean and Japanese. It will talk about problems identified in all these four language streams, with Chinese as the focus. Although according to various definitions, translation competence includes several parts, which are all required for a professional translator; this essay covers mainly the linguistic competence with tense and aspect issue as the main point. Meanwhile, some major causes of mistakes will be identified, such as interference of mother tongue, lack of second language proficiency. In the end, some possible ways for improvement are presented for reaching what are needed for a professional translator.
