A finding closely related to the completeness theorem is the Löwenheim-Skolem theorem (1915, 1920), named after Leopold Löwenheim, a German schoolteacher, and Skolem, which says that if a sentence (or a formal system) has any model, it has a countable or enumerable model (i.e., a model whose members can be matched with the positive integers).
At Virginia Tech, the Threat Assessment Team — a national model, whose members include the dean of students; the director of counseling; a university lawyer; and Dr. Deisinger, a psychologist who also holds the title of deputy police chief — meets weekly, discussing 6 to 20 cases.
There is a subclass of the category of contractive Ad modules whose members play the role of free objects.
The design was the work, for several years, of a committee of the Academy of Sciences, whose members ignored calligraphic models in favour of analytical and mathematical principles that, in retrospect, are said to have been characteristic of France during the so-called Age of Reason.
On the walls of the company are pictures of fifers and drummers, from Patrick H. Cooperman to clients such as the United States Army's Old Guard Fife and Drum Corps, whose members, wearing uniforms modeled after those of the musicians in George Washington's Continental Army, play at presidential inaugural parades and other events.
The dynamical approach, a branch of evolutionary game theory, develops formal models of how strategy choice evolves in a population whose members repeatedly play some game against each another.
The simple definition of model minority is an ethnic, racial or religious group whose members are perceived to achieve a higher degree of socioeconomic success than the population average.
The agreement is more likely to be a model for unions that represent sanitation workers and Housing Authority workers, whose members are not leaving in large numbers to the suburbs for higher salaries, like teachers and police officers.
The model seeks to educate and protect women by providing communities, whose members are likely to be subject to FGM, with information and knowledge about their commitment to social change.
Each one of the six duality models considered in this paper is, in fact, a family of dual problems whose members can easily be identified by appropriate choices of certain sets and functions.
