Test validityTest validity is the extent to which a test (such as a chemical, physical, or scholastic test) accurately measures what it is supposed to measure. In the fields of psychological testing and educational testing, "validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests". Although classical models divided the concept into various "validities" (such as content validity, criterion validity, and construct validity), the currently dominant view is that validity is a single unitary construct.
ShoeA shoe is an item of footwear intended to protect and comfort the human foot. Though the human foot can adapt to varied terrains and climate conditions, it is vulnerable, and shoes provide protection. Form was originally tied to function but over time shoes also became fashion items. Some shoes are worn as safety equipment, such as steel-toe boots, which are required footwear at industrial worksites. Additionally, fashion has often evolved into many different designs, such as high heels, which are most commonly worn by women during fancy occasions.
Falling (accident)Falling is the action of a person or animal losing stability and ending up in a lower position, often on the ground. It is the second-leading cause of accidental death worldwide and a major cause of personal injury, especially for the elderly. Falls in older adults are a major class of preventable injuries. Construction workers, electricians, miners, and painters are occupations with high rates of fall injuries. Long-term exercise appears to decrease the rate of falls in older people.
Nursing homeA nursing home is a facility for the residential care of older people, senior citizens, or disabled people. Nursing homes may also be referred to as care homes, skilled nursing facilities (SNF) or long-term care facilities. Often, these terms have slightly different meanings to indicate whether the institutions are public or private, and whether they provide mostly assisted living, or nursing care and emergency medical care. Nursing homes are used by people who do not need to be in a hospital, but cannot be cared for at home.
ShoemakingShoemaking is the process of making footwear. Originally, shoes were made one at a time by hand, often by groups of shoemakers, or cordwainers (sometimes misidentified as cobblers, who repair shoes rather than make them). In the 18th century, dozens or even hundreds of masters, journeymen and apprentices (both men and women) would work together in a shop, dividing up the work into individual tasks. A customer could come into a shop, be individually measured, and return to pick up their new shoes in as little as a day.
Aging in placeThe U.S. Centers for Disease Control and Prevention defines aging in place as "the ability to live in one's own home and community safely, independently, and comfortably, regardless of age, income, or ability level". Research in environmental gerontology indicates the importance of the physical and social environment of housing and the neighborhood (public space), as well as its implications for aging in place. Most adults would prefer to age in place—that is, remain in their home of choice as long as possible.
