Community educators have long known the value of direct experience in the learning process. Participatory Action Research (PAR) extends this philosophy to the realm of research. This article examines the value of using Single-Case PAR involving a member of an Appalachian camp staff community as a practitioner researcher working alongside university scientists in studying the type and conditions...

The acceptable range of speech level as a function of background noise level was investigated on the basis of word intelligibility scores and listening difficulty ratings. In the present study, the acceptable range is defined as the range that maximizes word intelligibility scores and simultaneously does not cause a significant increase in listening difficulty ratings from the minimum ratings. ...

Changes in intracellular and extracellular pH may influence the vulnerability of brain tissue to anoxic or ischemic damage. In the present study, we investigated whether the increased vulnerability of aged brain tissue to anoxic damage is associated with age-related alterations in pH regulation. We obtained evidence for altered pH regulation by measuring concurrent changes in intracellular and ...

Racial disparities in health among African American men (AAM) in the United States are extensive. In contrast to their White counterparts, AAM have more illnesses and die younger. AAM have colorectal cancer (CRC) incidence and mortality rates 25% and 50% higher, respectively, than White men. Due to CRC's younger age at presentation and high incidence among AAM, CRC screening (CRCS) is warranted...

The English stop voicing contrast is examined in both wordinitial position (via VOT) and word-final position (via the duration of the preceding vowel) in young adult speakers born and brought up in the Shetland Isles. The subjects’ parents were either also from Shetland, from elsewhere in Scotland, or England. All have identical phonemic stop systems, unambiguously so in initial position. The q...

Research carried out over a number of years provides a consistent picture of the experiences and needs of parents of disabled children. Recent studies, based on models of stress and coping, have identified factors which relate to high or low levels of parental distress. Whilst this research can provide useful information for service development, there appears to have been little change over the...
