stratified random sample of 9,975 female and 6,985 male active duty Navy personnel were mailed surveys in July 2001. The
response rates were 46 percent for females and 38 percent for males. Survey data were statistically weighted to allow
generalizations to be made to the Navy population. Among the major findings: rates of single parenthood have decreased for
both men and women; Family Care Certificate compliance is lower for men than for women; most Sailors make it their
responsibility to discuss birth control with their partner and most say they usually use birth control; less than half of female
officers and 59 percent of enlisted women would feel comfortable going to a corpsman about birth control. Point-in- time
pregnancy rates for E-5 to E-6 and 0-4 and 0-5 have increased. About 36 percent of enlisted pregnancies are planned. The most
recent pregnancy of 92 percent of female officers and 66 percent of female enlisted did not occur while they were in a sea
duty unit.

Speech Intelligibility in Noise Using Throat and Acoustic Microphones
Acker-Mills, Barbara E.; Houtsma, Adrianus J.; Ahroon, William A.; Apr. 2004; 23 pp.; In English

Rotary-wing aircraft crew are exposed to high levels of ambient noise that can cause hearing loss and impede speech
communication. Existing technology generally focuses on the listener and devices that can increase the signal-to-noise ratio
and decrease noise-induced hearing loss. However, speech intelligibility is still dependent on the quality of the original speech
signal. Throat microphones greatly reduce ambient noise in the original signal, thus enhancing the signal-to-noise ratio for the
listener, but higher frequencies are eliminated which may negatively affect speech intelligibility. Speech intelligibility for
signals generated by an acoustic microphone, a throat microphone, and the two microphones together was assessed using the
Modified Rhyme Test (MRT). Stimulus words were digitally recorded in a reverberant chamber with broadband noise intensity
at 90 dB(A) and 106 dB(A). Listeners completed the MRT task in the same seflings, thus simulating typical environments of
a rotary- wing aircraft. Results show that speech intelligibility is much worse for the throat microphone than for the acoustic
microphone, particularly for the higher noise level. In addition, no benefit is gained by adding the throat microphone signal
to the acoustic microphone signal.

The central goal of the Breast Cancer Behavioral Center is to further our understanding of the impact of biobehavioral
factors on genetic aspects of breast cancer in African American women. The Center has three aims: 1) To support an integrated,
interdisciplinary, Program of Research consisting of three synergistic Research Projects (with 4 supporting Cores), each of
which addresses an important cancer topic and includes psychological and/or behavioral issues. Thus, we propose research
projects with implications for breast cancer etiology, behavioral issues, and their interaction; 2) To encourage the development
of interdisciplinary thinking among the faculty involved in the Program of Research that can serve as a model for other
institutions. Thus, we propose to demonstrate, by example, the utility of an interdisciplinary approach by working together on
an integrated project that addresses important issues of interest to all members of the research team. We propose to bridge the
gap between biobehavioral research and epidemiologic approaches. 3) To facilitate the development of truly interdisciplinary
perspectives among new investigators in breast cancer research. Thus, we propose to provide interdisciplinary training through
both didactic and "hands- on" research, as well as informal seminars to outstanding young investigators who
represent the future of the field.
