Cleric (character class): The Cleric, Priest, or Bishop is a character class in "Dungeons & Dragons" and other fantasy role-playing games.  The cleric is a healer, usually a priest and a holy warrior, originally modeled on or inspired by the Military Orders.  Clerics are usually members of religious orders, with the original intent being to portray soldiers of sacred orders who have magical abilities, although this role was later taken more clearly by the paladin.

Geriatric care management: Geriatric care management (also known as "elder care management", "senior health care management" and "professional care management") is the process of planning and coordinating care of the elderly and others with physical and/or mental impairments to meet their long term care needs, improve their quality of life, and maintain their independence for as long as possible.  It entails working with persons of old age and their families in managing, rendering and referring various types of health and social care services.  Geriatric care managers accomplish this by combining a working knowledge of health and psychology, human development, family dynamics, public and private resources and funding sources, while advocating for their clients throughout the continuum of care.  For example, they may assist families of older adults and others with chronic needs such as those suffering from Alzheimer's disease or other dementia.

Nixon Doctrine: The Nixon Doctrine (also known as the Guam Doctrine) was put forth during a press conference in Guam on July 25, 1969 by US President Richard Nixon and later formalized in his speech on Vietnamization on November 3, 1969.  According to Gregg Brazinsky, Nixon stated that "the United States would assist in the defense and developments of allies and friends", but would not "undertake all the defense of the free nations of the world."  This doctrine meant that each ally nation was in charge of its own security in general, but the United States would act as a nuclear umbrella when requested.  The Doctrine argued for the pursuit of peace through a partnership with American allies.  The Nixon Doctrine implied the intentions of Nixon shifting the direction on international policies in Asia, especially aiming for "Vietnamization of the Vietnam War."

Health belief model: The health belief model (HBM) is a psychological health behavior change model developed to explain and predict health-related behaviors, particularly in regard to the uptake of health services.  The health belief model was developed in the 1950s by social psychologists at the U.S. Public Health Service and remains one of the best known and most widely used theories in health behavior research.  The health belief model suggests that people's beliefs about health problems, perceived benefits of action and barriers to action, and self-efficacy explain engagement (or lack of engagement) in health-promoting behavior.  A stimulus, or cue to action, must also be present in order to trigger the health-promoting behavior.
