The period of adolescence, i.e., the period between childhood and adulthood may be long or short, depending on social expectations and on society’s definition as to what constitutes maturity and adulthood. ①In primitive societies adolescence is frequently a relatively short period of time, while in industrial societies with patterns of prolonged education coupled with laws against child labor, the period of adolescence is much longer and may include most of the second decade of one’s life. Furthermore, the length of the adolescent period and the definition of adulthood status may change in a given society as social and economic conditions change. Examples of this type of change are the disappearance of the frontier in the latter part of the nineteenth century in the United States, and more universally, the industrialization of an agricultural society. In modem society, ceremonies for adolescence have lost their formal recognition and symbolic significance and there no longer is agreement as to what constitutes initiation ceremonies. Social ones have been replaced by a sequence of steps that lead to increased recognition and social status. ②For example, grade school graduation, high school graduation and college graduation constitute such a sequence, and while each step implies certain behavioral changes and social recognition, the significance of each depends on the socio-economic status and the educational ambition of the individual. Ceremonies for adolescence have also been replaced by legal definitions of status roles, rights, privileges and responsibilities. It is during the nine years from the twelfth birthday to the twenty-first that the protective and restrictive aspects of childhood and minor status are removed and adult privileges and responsibilities are granted. The twelve-year-old is no longer considered a child and has to pay full fare for train, airplane, theater and movie tickets. Basically, the individual at this age loses childhood privileges without gaining significant adult rights. At the age of sixteen the adolescent is granted certain adult rights which increase his social status by providing him with more freedom and choices. He now can obtain a driver’s license; he can leave public schools; and he can work without the restrictions of child labor laws. At the age of eighteen the law provides adult responsibilities as well as rights; the young man can now be a soldier, but he also can marry without parental permission. At the age of twenty-one the individual obtains his full legal rights as an adult. He now can vote; he can buy liquor; he can enter into financial contracts; and he is entitled to run for public office. No additional basic lights are acquired as a function of age after majority status has been attained. None of these legal provisions determine at what point adulthood has been reached but they do point to the prolonged period of adolescence. The period of adolescence is much longer in industrial societies because ______.

Technological characteristics of the factory of the future will be influenced by both "science push" and "market pull". Science push relates to the many scientific developments that are being announced from laboratories around the world. ①The manufacturing community is alert to these developments and when creative people visualize opportunities to solve major problems with new scientific developments, they are responsive to initiate major project to attempt to capture a competitive edge. Market pull is the other dimension. The manufacturing community sees opportunities to gain a competitive edge by drawing existing or emerging technologies on to the shop floor, and they are willing to invest in the future. The driving force in both cases is the desire to increase productivity and quality. History has demonstrated that both phenomena are at work in the manufacturing environment. ②Underlying the future of the manufacturing environment of tomorrow are the strategic technologies that the we recognize today as playing an important role in our planning in industrial and university research laboratories. Let me elaborate on what I consider the strategic technologies in the laboratory with both medium and long-range perspectives on the future. My strategic technologies include: new materials (including polymers, alloys, ceramics and composites, and superconductors ), computer engineering, microelectronics, micro-fabrication, photonics, and manufacturing system (automation for machines and processes, new processes, engineering management). The reality of the impact of the strategic technologies which I have mentioned is not an issue. What are the issues include: how rapidly will their impact be left, how will the capital investments required be justified, and how will we educate the workforce to implement and manage them. I believe these issues will be resolved in an evolutionary way rather than as a new industrial revolution. There are already unfortunate examples of failure in attempts to implement individual views of factories of the future. ③The underlying problems will surface when we attempt too much, too soon, and without a thorough knowledge of all of the important features of strategic technologies and of whether they are fit for an effective manufacturing facility: The lack of standards has been recognized as a major deterrent to integration, and major steps have been taken on a national and worldwide basis to correct the situation. We cannot overestimate the power of the human being to adapt and to succeed. We have not yet duplicated this power with the computer. However, we have achieved the ability to use the computer to make the human more productive, more reliable and more powerful. This is perhaps the beginning for developing a more focused view of what we mean by the factory of the future. The issue of strategic technologies is of great importance to the development of the factory of the future. It is a matter of survival. The word "deterrent" (Line 10, Par
