A Search for CP(T) Violation in B Decays at OPAL

A search for CP(T) violation is performed and the fractional difference between the $b$ and $\bar b$ hadron lifetimes is measured using reconstructed secondary vertices in inclusive B hadron decays culled from 3.1 million $Z^0 \to q \bar q$ events. The data were collected by the OPAL experiment at the LEP collider at CERN at $\sqrt{s} \approx 91$ GeV from 1991-1995.Comment: 7 pages, 4 figures. Proceedings for talk 4-16 given at the DPF99 Conference in Los Angeles, Californi

Objects in transformation

Traces and marks left behind tell the stories of buildings and their materials. Remnants of the past remain, while new construction is layered on top, creating a kind of palimpsest. Artifacts of material time - rust, erosion, growth - are inevitable, yet often feared. Typically in search of longevity, architects gravitate toward materials and finishes that promise durability. My work questions some of the assumptions we have about material quality as a function of time. Through experimental artifacts, this thesis reorients our perceptions of time’s effects on the built and natural environments, and introduces a new and expanded time scale

A study of policies and practices in the recruitment of college students by business organizations

The thesis plan. Since the recruitment of college students by businesses ha.s become so important, more research should be conducted in this field. The purposes of this thesis are: to give some insight into policies and practices in the recruitment of college students by the present day business world, and to evaluate these policies and practices in order that the future of college recruitment may be more fully understood
