The current societal and professional context presents a variety of ethical challenges to decision makers. The importance of educational preparation for ethical decision-making and ethical leadership has been addressed in the literature of library and information science (LIS), among other professions. However, it can be quite difficult to measure the impact of professional ethics education on students. This article is based on an evaluation of published original research related to ethics education in disciplines supported by professional education, including education, nursing, allied health, journalism, social work, public health, engineering, and LIS. The study considers data related to research design, methodologies used, populations studied, approaches to measuring impact, levels of impact, and publication in the journal literature. Results indicate more extensive research in education and nursing as compared with other fields, a lack of baseline data gathering for comparison, a reliance on a limited number of data-gathering techniques, and a tendency toward studying alumni over current students  相似文献

We consider some issues of the development of the national information infrastructure in the field of innovation, including a national system of accounting for the results of scientific and technical activities (RSTA) and a national new-generation research computer network (NNGRCN). The current state of the national system of scientific and technical information and its resources for information support of innovation processes are analyzed. In the context of further development of the Commonwealth of Independent States (CIS), we propose a Conception of scientific and technical support for programs and projects of NIS member-states in the field of innovation, making it possible to incorporate the existing innovation-oriented information resources into a joint distributed integrated information system as well as to create new information resources and technologies.  相似文献
