An example of the use of idealization in physics is in Boyle's Gas Law: Given any x and any y, if all the molecules in y are perfectly elastic and spherical, possess equal masses and volumes, have negligible size, and exert no forces on one another except during collisions, then if x is a gas and y is a given mass of x which is trapped in a vessel of variable size and the temperature of y is ...
The nurse scheduling problem (NSP), also called the nurse rostering problem (NRP), is the operations research problem of finding an optimal way to assign nurses to shifts, typically with a set of hard constraints which all valid solutions must follow, and a set of soft constraints which define the relative quality of valid solutions.

One method of research for evidence-based practice in nursing is 'qualitative research': The word implies an entity and meanings that are not experimentally examined or measured in terms of quantity, amount, frequency, or intensity. With qualitative research, researchers learn about patient experiences through discussions and interviews.
Decision trees, influence diagrams, utility functions, and other decision analysis tools and methods are taught to undergraduate students in schools of business, health economics, and public health, and are examples of operations research or management science methods. These tools are also used to predict decisions of householders in normal and ...
The dominant research method is the randomised controlled trial. Qualitative research is based in the paradigm of phenomenology , grounded theory , ethnography and others, and examines the experience of those receiving or delivering the nursing care, focusing, in particular, on the meaning that it holds for the individual.
Assess the weight of evidence for this middle-level influence, which is conditional on bottom-level influences 5. Repeat 3 and 4 for the remaining middle-level and bottom-level influences These three steps are conducted in the aim of determining the extent to which the influences exist in the process, alone and in different combinations, and ...
Idealised populations are those following simple one-locus models that comply with assumptions of the neutral theory of molecular evolution. The effective population size is normally smaller than the census population size N , partly because chance events prevent some individuals from breeding, and partly due to background selection and genetic ...
The main idea [of the ideal observer theory] is that ethical terms should be defined after the pattern of the following example: "x is better than y " means "If anyone were, in respect of x and y, fully informed and vividly imaginative, impartial, in a calm frame of mind and otherwise normal, he would prefer x to y."
