Book Description
A closed course nighttime legibility study measured legibility distance for 6-in. letters using Highway Series D and two experimental fonts, Clearview Condensed Road and a D-Modified font. The Clearview font has a thinner stroke width than Series D and was used for white-on-green signs. The D-Modified font has a thicker stroke width than Series D and was used for black letters on white, yellow, and orange backgrounds. Three types of retroreflective sheeting were tested: ASTM Types III, VIII, and IX.

Book Description
This project was conducted to provide results that the Texas Department of Transportation (TxDOT) could use to help make decisions about their guide sign policies. The specific issues that were addressed include the type of font and retroreflective sheeting that should be specified on guide signs ranging from large shoulder-mounted freeway guide signs, to medium-sized guide signs such as destination and distance signs, and even including small guide signs such as county road name signs. The researchers performed a nighttime legibility study using a total of 30 subjects divided into three age groups.

Book Description
Awarded a 2012 AJN Book of the Year Award! Why focus on the negative aspects of growing old while most older adults are leading positive, fulfilling, and active lives even while dealing with the changes associated with aging and chronic illnesses? Promote healthy aging; learn what it means to age successfully; and develop the tools and resources that can optimize well-being during the later years in life with the guidance you'll find inside. The author, a nationally recognized expert in the field of gerontology addresses the physical, psychosocial, and spiritual needs of older adults based on a holistic, mid-range nursing theory of successful aging. Contributions from healthcare professionals in exercise physiology, nutrition, pharmacy and elder law help you understand how these disciplines work together to benefit patients.
