What we have learned about policy-research linkage from providing a rapid response facility for international healthcare comparisons to the Department of Health in England

In this paper we reflect on our experience of providing a rapid response facility for international healthcare policy comparisons to the English Department of Health. We examine the challenges of developing sustained relationships with policy officials while providing an 'on-demand' service in an environment with high turnover of policies and staff. It may be easier for policy makers to draw on researchers in such a setting than for researchers to foster 'linkage and exchange' relationships with policy makers. Under the facility, knowledge transfer has mostly been from researchers to policy officials, affording us little insight into the policy process or the impact of our work

Time and dose dependency of bone-sarcomas in patients injected with radium-224

The time course and dose dependency of the incidence of bone-sarcomas among 900 German patients treated with high doses of radium-224 is analysed in terms of a proportional hazards model with a log-normal dependency of time to tumor and a linear-quadratic dose relation. The deduced dose dependency agrees well with a previous analysis in terms of a non-parametric proportional hazards model, and confirms the temporal distribution which has been used in the Radioepidemiological Tables of NIH. However, the linear-quadratic dose-response model gives a risk estimate for low doses which is somewhat less than half that obtained under the assumption of linearity. Dedicated to Prof. W.

The Eulogy

Eulogy for Mordecai W. Johnson by Benjamin E. Mays, President Emeritus of Morehouse Colleg

The Relevance of Mordecai Wyatt Johnson

Editor\u27s note: The following was excerpted from the inaugural lecture in honor of the late Dr. Mordecai Wyatt Johnson. Dr. Johnson, who died in 1976 at the age of 86, was the president of Howard University from 1926 to 1960. The annual lecture series in his honor was inaugurated on January 27, 1978 with an address by Dr. Benjamin E. Mays, president emeritus of Morehouse College and a friend of Dr. Johnson\u27s

On nilpotent but not abelian groups and abelian but not cyclic groups

AbstractWe derive asymptotic formulas for A(n) − C(n) = | {m < n: every group of order m is abelian but not every group of order m is cyclic}|, N(n) − A(n) = | {m < n: every group of order m is nilpotent but not every group of order m is abelian}|, and related counting functions from group theory
