Aging and Driving
Anstey, K.J. & Wood, J. (2011). Chronological age and age-related cognitive deficits are associated with an increase in multiple types of driving errors in late life. Neuropsychology 25(5): 613-621.
In "Chronological age and age-related cognitive deficits…" Anstey & Wood (2011) outline the purpose of the research as being to foster greater understanding of the factors involved in driving skills that diminish with age. In particular, the authors are concerned with the cognitive factors that impact driving ability. The authors warn against blanket generalizations about seniors, many of whom retain their ability to drive safely well into old age. The gap in research the authors are filling is related to the specific cognitive changes that take place as a matter of the aging process, and how those changes impact seniors who regularly drive. According to the authors, their research has direct real-world application for the ergonomics of driving experiences in terms of improved road signs and continuing driver education for seniors.
A review of literature reveals that from a neurophysiological standpoint, aging impacts frontal lobe processes and functions more than other brain regions and functions. Decision making and response time are two specific areas that diminish naturally with age. In previous research measuring the driving errors that seniors make, the authors discovered that "the highest rates of errors involved failure to...
S." (Liu, 2008) the actual solution to the challenges facing the health care system in the United States is one that makes a requirement of three components: implementing tort reforms; mandating the use of best practices; and driving systemic process improvement. (Liu, 2008) This report states that the threat of litigation gets in the way of health care delivery in that is "causes providers to hide problems and engage in unnecessary procedures
Windy McNernev and Robert West (2007), both with the University of Notre Dame, Notre Dame, India, explain that returning the DVD while running errands depicts an illustration of effective prospective memory. Substantial documentation signifies that in various instances, the accessibility of one's effective memory ability or attentional resources can be vital for the comprehension of deferred intentions.

For example, Massachusetts and California have made recent improvements by upgrading care quality and professionalizing care; by contrast, despite Florida's large population of seniors and the beginning of a coalition of patients, families, and workers on behalf of better care, the state administration remains inflexible in their funding approach (Fitzgerald 30). Nursing homes and other long-term-care facilities are unique among low-wage labor markets in that government, in effect, sets wages
Cross-Sectional Study to Determine Factors in the Educational Advancement of the Licensed Practical Nurse to the Registered Nurse in the State of North Carolina According to the Harvard Nursing Research Institute, United States nursing school enrollments dropped by 20.9% from 1995 to 1998 (Healthcare Review, 2000). Behind headlines such as this one are the overwhelming issues which threaten the nursing workforce: 1) staffing cuts, 2) mandatory overtime, and 3) the
Pharmaceutical industries have to operate in an environment that is highly competitive and subject to a wide variety of internal and external constraints. In recent times, there has been an increasing trend to reduce the cost of operation while competing with other companies that manufacture products that treat similar afflictions and ailments. The complexities in drug research and development and regulations have created an industry that is subject to intense
For instance, a decline in peripheral vision may impact the ability to pass approaching vehicles safely, and the decreased range of motion in an older person's neck may impair the ability to look behind when backing up. Also, reaction time decreases by almost 40% on average from age 35 to 65 (Jackson, 1999). It also appears that the aging process may affect cognitive skills. Short-term memory loss, for instance, can
