Female college athletes: a special population for health promotion in primary care.

Female college athletes constitute a population with potential health problems beyond those of their age-mates. The expectations of the elite college athlete for academic and athletic accomplishment and for exemplary personal behavior, in combination with the typical developmental crises of late adolescence, create health risks. This presents the opportunity for effective health promotion as a part of primary care for these young women. The HealthCoRE Program at Texas Tech University Health Sciences Center School of Nursing is an example of how a program approach using a community health perspective, in contrast to an episodic or an "array-of-available-services-cafeteria" approach, can affect the health of female college athletes. Program elements include identification of group and individual health risks and health information interests, individual physical examination including a gynecologic examination, individual client contracts for group and individual activities, and crisis intervention. Three years of experience with the program shows value both from the athletes' perspectives and from their coaches' perspectives. Nurse practitioners are the ideal providers for this type of service because of their knowledge of the community health approach, their skills in health promotion and disease prevention, and their use of health teaching as a therapeutic tool.

Rural health care--in the "future perfect".

Rural health care can thrive if innovative tactics are used. Four assumptions can influence how health care occurs in rural areas. One assumption is to view the world in a "both/and" view of human phenomena. Second is to recognize that competition is a dominant mode; and that using integrative/collaborative solutions could enhance all health care. Cultural ethnocentricity and professional ethnocentricity, the third assumption, are counterproductive. This is especially true in rural America. The fourth assumption, one can only accomplish what one can imagine, sets an infinite range of possibilities for rural health care. Education must change to incorporate a commitment to collaboration and to integrative, innovative solutions to problems.

Responses elicited from medial superior olivary neurons by stimuli associated with binaural masking and unmasking.

The responses of binaural neurons of the medial superior olive were measured as a function of interaural temporal differences for tones and as a function of signal-to-noise ratio under homophasic and antiphasic masking conditions. The degree of neural response synchrony to the frequency of the signal was related to the degree of behavioral detectability of the signal in the homophasic, but not the antiphasic masking condition. For the antiphasic condition, a decrease in discharge rate resulted from the addition of the signal to the noise, similar to the decrease which occurred when interaural temporal differences were introduced in the tonal stimuli. The results are compatible with a model in which interaural temporal-difference information arriving over monaural afferents in the form of synchronized impulses is mapped into a place code by a neural coincidence-detection device. Several differences were noted between the responses to tones found in the present experiment and those reported by others. These differences were attributed mainly to differences among the experimental procedures in use among the various reporting laboratories.

Neural responses elicited by stimuli associated with masking of low-frequency, monaural tonal signals by noise.

The responses of low-frequency, primary-like neurons of the ventral cochlear nucleus were measured as a function of signal-to-noise ratio for gated tonal signals and noise maskers that were varied in bandwidth and duration. For a given signal-to-noise ratio, each of the maskers is known to produce the same amount of masking in psychophysical experiments. The neural discharge rates measured in the present experiment were different, however, for each of the maskers for each signal-to-noise ratio. In contrast, all three maskers produced the same orderly relationship between signal-to-noise ratio and the degree of neural synchrony to the signals. It is concluded that information concerning the presence and relative strength of a low-frequency tonal signal in a background of masking noise is carried by the nervous system as the degree to which responses are synchronized to the phase of the signal.
