Scientific Workforce

The science and engineering workforce has aged rapidly in recent years, both in absolute terms and relative to the workforce as a whole. This is a potential concern if the large number of older scientists crowds out younger scientists, making it difficult for them to establish independent careers. In addition, scientists are believed to be most creative earlier in their careers, so the aging of the workforce may slow the pace of scientific progress. We develop and simulate a demographic model, which shows that a substantial majority of recent aging is a result of the aging of the large baby boom cohort of scientists. However, changes in behavior have also played a significant role, in particular, a decline in the retirement rate of older scientists, induced in part by the elimination of mandatory retirement in universities in 1994. Furthermore, the age distribution of the scientific workforce is still adjusting. Current retirement rates and other determinants of employment in science imply a steady-state mean age 2.3 y higher than the 2008 level of 48.6.

Earthquake Science

Earthquake science and engineering are experience-driven fields in which lessons are learned after each significant earthquake. Remote sensing represents a suite of technologies that can play a significant role in documenting the effects of earthquakes and lead to important developments in our understanding of earthquakes. This paper describes current remote sensing technologies and the experience to date in using them in earthquake studies. The most promising activities that may benefit from remote sensing data products are identified, as well as the challenges that may impede the widespread use of remote sensing in earthquake studies. A comprehensive review of the use of remote sensing to document the effects of the 2003 Bam, Iran earthquake is presented, and recommendations for future developments in remote sensing in the context of earthquake science and engineering are provided.

The study and preservation of cultural heritage is a multidisciplinary field where Materials Science and Corrosion Science have a very significant role to play. This chapter discusses how materials and corrosion scientists can follow a career in cultural heritage. It highlights the particular challenges that these disciplines encounter in the study and preservation of cultural heritage materials and the exciting career paths offered in museums, monuments, and relevant academic and research institutions. The applications for science and engineering skills to cultural materials are diverse, including the reverse engineering necessary to reconstruct ancient technologies used for materials production, the examination and condition assessment of often complex finds and structures, and the development of innovative treatment methods for their protection and conservation for future generations. Within this range of challenges and materials, numerous career paths are available that lead to specialisations within the sub-fields of archaeological science and conservation science.
