Although management principles have been implemented since ancient times, most management scholars trace the beginning of modern management thought back to the early 1900s, beginning with the pioneering work of Frederick Taylor (1856-1915) Taylor was the first person to study work scientifically. He is most famous for introducing techniques of time and motion study, differential piece rate systems, and for systemtically specializing the work of operating employees and managers. Along with other pioneers such as Frank and Lillian Gilbreth, Taylor set the stage, labeling his philosophy and methods “scientific management”. At that time, his philosophy, which was concerned with productivity, but which was often misinterpreted as promoting worker interests at the expense of management, was in marked contrast to the prevailing industrial norms of worker exploitation.
The time and motion study concepts were popularized by Frank and Lillian Gilbreth. The Gilbreths had 12 children. By analyzing his children’s dishwashing and bed making chores, this pioneer efficiency expert, Frank Gilbreth, hit on principles whereby workers could eliminate waste motion. He was memorialized by two of his children in their 1949 book called “Cheaper by the Dozen”.
The Gilbreth methods included using stop watches to time worker movements and special tools (cameras and special clocks) to monitor and study worker performance, and also involved identification of “therbligs” (Gilbreth spelled backwards) - basic motions used in production jobs. Many of these motions and accompanying times have been used to determine how long it should take a skilled worker to perform a given job. In this way an industrial engineer can get a handle on the approximate time it should take to produce a product or provide a service. However, use of work analysis in this way is unlikely to lead to useful results unless all five work dimensions are considered, physical, psychological, social, cultural, and power.

The word “prevailing” is closest in meaning to ________.

In the early years of television, educational specialists believed that it would be very useful in teaching and learning. Many schools have bought television sets, intending to use them effectively to improve the quality of education; but actually, they are not used properly in classrooms. Meanwhile, children spend the majority of their out-of-school hours watching TV and their typical school days proceed as if television did not exist. There are some explanations for the failure of television to get the interest of the teachers. Firstly, the schools that purchased television sets have not set aside money for equipment repairs and maintenance so these television sets are sooner and later out of work. Secondly, these schools have not found an effective way to train teachers to integrate television into their ongoing instructional programs. Lastly, most teachers do not regard the quality of television and its usefulness in the classroom. Teachers at the schools work hard for at least twelve years to train their students to become good readers. However, according to recent statistics, teenagers seldom spend their free time reading books and newspapers but watching television instead. 

Teenagers seldom spend their free time _______.
