Attributes of visually impaired children such as chronological age, grade placement, visual acuity, sex, arithmetic, and reading achievement are of primary concern in this investigation. These attributes or variables are studied in relation to their association with or influence upon the integration of visually impaired children into classes and activities with normally seeing children in the Detroit Public Schools. Findings are believed to be generalizable in view of the diverse abilities, experiences, and ethnic background of the general and special student population in the large public school district studied, and given the flexibility necessarily deployed in programming to provide meaningful learning experiences for all students enrolled.

SummaryOral candidiasis is a significant infectious process in the elderly. Clinically, it is encountered by the dental practitioner in a variety of ways, including acute and chronic forms. C albicans is also an important factor in the development of angular cheilitis and median rhomboid glossitis.Numerous systemic and local conditions common to the elderly predispose this population to oral Candida infections. Frequent combinations of these multiple risk factors increase the occurrence of oral candidiasis in older adults. It is imperative that health care providers be cognizant of systemic and local predisposing factors and typical clinical signs and symptoms to provide rational treatment for oral C albicans infections.

Abstract
Despite Federal directives calling for an integrated approach to strengthening the resilience of critical infrastructure systems, little is known about the relationship between human behavior and infrastructure resilience. While it is well recognized that human response can either amplify or mitigate catastrophe, the role of human or psychological resilience when infrastructure systems are confronted with surprise remains an oversight in policy documents and resilience research. Existing research treats human resilience and technological resilience as separate capacities that may create stress conditions that act upon one another. There remains a knowledge gap regarding study of those attributes in each that build infrastructure resilience as an integrated system of humans and technologies. This work draws on concepts found in the resilience engineering and psychology literature to examine the dynamic relationships between human resilience and the resilience of complex, socio-technical critical infrastructure systems. We identify and organize 18 system capacities and 23 human capacities that influence infrastructure resilience. We then correlate individual human and system resilience capacities to determine how each influences four socio-technical processes for resilience: sensing, anticipating, adapting, and learning. Our analysis shows that the human and technical resilience capacities reviewed are interconnected, interrelated, and interdependent. Further, we find current literature is focused more on cognitive and behavioral dimensions of human resilience and we offer ways to better incorporate affective capacities. Together, we present a simple way to link the resilience of technological systems to the cognitive, behavioral, and affective dimensions of humans responsible for the system design, operation, and management.

Glucose-6-phosphate dehydrogenase (G6PD) protects erythrocytes from oxidative stress and hemolysis; G6PD deficiency is the most prevalent enzymopathy. The United States military routinely performs tests to prevent exposing G6PD-deficient personnel to antimalarial drugs that might cause life-threatening hemolytic reactions. In addition, G6PD is a key determinant of vascular function, and its deficiency can lead to impaired nitric oxide production and greater vascular oxidant stress—precursors to atherosclerosis and cardiovascular disease. Using military medical records, we performed a retrospective, cross-sectional study to investigate whether deficient G6PD levels are associated with a higher prevalence of cardiovascular disease than are normal levels, and, if so, whether the relationship is independent of accepted cardiovascular risk factors.
