Challenges to understanding spatial patterns of disease: philosophical alternatives to logical positivism.

Most studies of disease distribution, in medical geography and other related disciplines, have been empirical in nature and rooted in the assumptions of logical positivism. However, some of the more newly articulated philosophies of the social sciences, and of social theory, have much to add in the understanding of the processes and mechanisms underlying disease distribution. This paper represents a plea for creative synthesis between logical positivism and realism or structuration, and uses specific examples to suggest how disease distribution, as a surface phenomenon, can be explained using deeper analysis.

Assessment of basic cognitive abilities in relation to cognitive deficits.

A modal model of information-processing was used to select a battery of nine tasks of basic cognitive ability (learning, relearning, reaction time, probe recall, Sternberg search, self-paced probe, stimulus discrimination, tachistoscopic full report, tachistoscopic partial report). Parameters from these tasks operationalized the model. After extensive pilot testing of the tasks to establish reliability, we tested 40 subjects (20 with mental retardation and 20 college students) on all tasks and the WAIS-R. The parameters from the tasks were generally reliable (.7 through .9) and had low correlations with IQ (average about .37). Nearly all of the major cognitive parameters differentiated significantly between groups. A subset of the basic cognitive parameters predicted IQ with an estimated multiple correlation in the general population of .72. Prediction of IQ using basic cognitive parameters was better for subjects with mental retardation than for college students. A modified version of the modal model was supported. Results show that individual differences in higher mental processes are highly dependent on basic cognitive abilities and can be predicted from them. These findings have substantial implications for the development of models of information-processing.

A broader conception of mood experience.

The experience of a mood consists of more than emotional states such as happiness, anger, sadness, or fear. It also includes mood management processes that can facilitate or inhibit the experience of the mood reaction. A multidomain framework is described for organizing such experience, and 2 studies are reported that analyzed separately emotion-related and emotion-management-related mood experiences. In both studies, emotion-related experience, including physical, emotional, and cognitive subdomains, could be characterized by Pleasant-Unpleasant and Arousal-Calm dimensions. Also, both studies yielded evidence for the emotion-management dimensions of Plans of Action, Suppression, and Denial. These broader dimensions of mood experience predicted criterion variables such as empathy better than Pleasant-Unpleasant and Arousal-Calm dimensions alone.

Emergency medical service: delays, response time and survival.

A major concern in emergency medical services (EMS) planning has been the need to minimize ambulance response time, only one of several delays in reaching definitive care. Other important delays include patient delay in seeking medical care and dispatch delay. In this study, the importance of response time in light of other delays is discussed, and response time as one determinant of patient survival is analyzed, using Seattle's EMS system as a case study. The major conclusion is that paramedic response times influence short-term patient survival.
