In the analysis of the South African NSC diagnostic reports, the Department of Education prepared areas of learners' struggle have proved to repeat themselves from 2017 to 2020. The classroom practices of Life Sciences teachers, focusing on teacher knowledge, were observed in a sample of schools in the province of Gauteng, South Africa. The investigation aimed to investigate these practices of Life Sciences teachers and consequently diagnose teaching difficulties. Data was collected through interviews and observations in a multi-case study approach and analyzed using Mudau's (2016) Classroom Practice Diagnostic Framework. This study reveals that teachers' classroom practices contribute to the teaching difficulties they experience when considering teachers' knowledge of the Life Sciences content, the teaching context, and learner understanding.

Due to the terrorist attacks of 9/11 and the anthrax letters of a few weeks later, the concept of dual use has spread widely in the life sciences during the past decade. This article is aimed at a clarification of the dual use concept and its scope of application for the life sciences. Such a clarification would greatly facilitate the work of policymakers seeking to ensure security while avoiding undesirable interventions of government in the conduct of science. The article starts with an overview of the main developments in life sciences in relation to dual use. This is illustrated by discussions on synthetic biology and dual use. The findings lead to a reconsideration of the dual use concept. An area in need of further attention is to what extent threats and intentions should have impact on the definition of dual use. Possible threats are analyzed against the background of the phenomenon of securitization of health care and life sciences: considering these sectors of society in security terms. Some caveats that should be taken into account in a dual use policy are described. An acceptable, adequate and applicable definition of the dual use concept could help researchers, universities, companies and policy makers. Such a definition should build upon, but go beyond, the view developed in the influential Fink-report, which concentrates on the so-called 'experiments of concern', e.g. experiments that enhance the virulence of pathogens (National Research Council of the National Academies 2004) It will be argued that—in addition to these more technical aspects—a definition of dual use should include the aspect of threats and intentions.

Dr. Sherman P. Vinograd fulfilled the roles of Chief of Medical Science and Technology and Director of Biomedical Research at the National Aeronautics and Space Administration (NASA) from the fall of 1961 until the spring of 1979. In this role he shaped, organized, and directed NASA's program of medical research as a funded program of studies, which was carried out in not only NASA Center laboratories, but also in university, industry, and other government laboratories and hospitals all over the country. It produced a large substrate of information through its bed rest studies, vestibular, bone, neuromuscular, hematology, and cardiovascular researches. It also produced valuable fall-out, such as an accurate bone density measurement technique which is now in common clinical use. ; His major activities during this career were conceptualizing, establishing, and chairing the Space Medicine Advisory Group (SPAMAG) charged with defining the earth-based and space-based research and life-support requirements for a manned orbiting research laboratory. This group designed a carefully planned study utilizing highly qualified, specialized members of the scientific community. They postulated a non-existent orbiting laboratory to be designed according to the needs of future human flight crews and requirements for human spaceflight information. This would result in the creation of Skylab. ; He was also responsible for establishing the In-flight Medical Experiments Program in preparation for the Apollo series of manned space flights. This program was a series of carefully designed flight crew studies derived from proposals by qualified scientists both from within and outside NASA to evaluate human responses to spaceflight. ; In addition, Dr. Vinograd developed a supportive Research and Development Program necessary to provide pertinent ground-based data and to advance state-of-the-art medical measurement technology, a major development of which was the Integrated Medical and Behavioral Laboratory Measurement System (IMBLMS). This consisted of medical experiments and accompanying equipment necessary to perform them that was used from the Gemini through the Skylab manned space flight programs. Carried aboard virtually any post-Apollo space vehicle by virtue of its rack and module design, these designs were used well into the future. He also fostered the continuing ground-based medical research program sponsored and/or conducted by NASA. ; The Dr. Sherman P. Vinograd Aerospace Exploration collection consists of artifacts, books, correspondence, financial materials, newspapers, photographs, plaques, printed materials, and reports relating to Dr. Vinograd's early life, his career as an M. D. prior to joining NASA, his years as a physician and researcher at NASA, and the other professional organizations and projects in which he was involved both during and after these periods. ; Box 5, Folder 22
