More specifically, it is to provide an impetus for the design of standardized principles of Information/Cybersecurity course. To achieve this, a survey of colleges and universities that offer the course was conducted. Several schools of engineering and business, in universities and colleges across several countries were surveyed to generate necessary data. Effort was made to direct the questionnaire only to Computer Information System (CIS), Computer Science (CS), Management Information System (MIS), Information System (IS) and other computer-related departments. The study instrument consisted of two main parts: one part addressed the institutional demographic information, while the other focused on the relevant elements of the course. There are sixty-two (62) questionnaire items covering areas such as demographics, perception of the course, course content and coverage, teaching preferences, method of delivery and course technology deployed, assigned textbooks and associated resources, learner support, course assessments, as well as the licensure-based certifications. Several themes emerged from the data analysis: (a) the principles course is an integral part of most cybersecurity programs;(b) majority of the courses examined, stress both strong technical and hands-on skills;(c) encourage vendor-neutral certifications as a course exit characteristic;and (d) an end-of-course class project, remains a standard requirement for successful course completion. Overall, the study makes it clear that cybersecurity is a multilateral discipline, and refuses to be confined by context and content. It is envisaged that the results of this study would turn out to be instructive for all practical purposes. We expect it to be one of the most definitive descriptive models of such a cardinal course, and help to guide and actually, shape the decisions of universities and academic programs focusing on information/cyber security in the updating and upgrading their curricula, most especially, the foundational principles course in light of new findings that are herein articulated.展开更多

Researchers and decision-makers can obtain a variety of evidence resources about safety in order to evaluate the safety profile for postmarketing Chinese medicines. A registry study on ten Chinese medicine injections for postmarketing surveillance has come to the end. From such a study observing more than 300,000 patients for more than 4 years, a theoretical research question emerges, that is, how to identify and evaluate safety evidence systematically. We put forward a brand new research paradigm on the theory level, which is to establish a body of evidence on safety evaluation for postmarketing Chinese medicine. Therefore, multiple information sources were explored and extracted from preclinical experiments for toxicity, postmarketing clinical trials for efficacy and safety evaluation, registry study for surveillance, retrospective data analysis from hospital information system and spontaneous response system, and case reports and systematic review from literature. Greater efforts for this idea and cooperation with experts in this field both in China and abroad are urgently needed.展开更多
