In mathematics, in the realm of group theory, a group is said to be critical if it is not in the variety generated by all its proper subquotients, which includes all its subgroups and all its quotients. [1] Any finite monolithic A-group is critical. This result is due to Kovacs and Newman. [2] But not every monolithic group is critical. [3]
If a focus group is held in a laboratory setting with a moderator who is a professor and the recording instrument is obtrusive, the participants may either hold back on their responses and/or try to answer the moderator's questions with answers the participants feel that the moderator wants to hear.
Criticality (status), a milestone in the commissioning of a nuclear power plant; Criticality accident, an uncontrolled nuclear chain reaction; Nuclear criticality safety, the prevention of nuclear and radiation accidents resulting from an inadvertent, self-sustaining nuclear chain reaction; Prompt critical, an assembly for each nuclear fission ...
The critical point is described by a conformal field theory. According to the renormalization group theory, the defining property of criticality is that the characteristic length scale of the structure of the physical system, also known as the correlation length ξ, becomes infinite. This can happen along critical lines in phase space.
Critical mathematics pedagogy is an approach to mathematics education that includes a practical and philosophical commitment to liberation. [1] Approaches that involve critical mathematics pedagogy give special attention to the social, political, cultural and economic contexts of oppression, as they can be understood through mathematics.

The failure mode may then be charted on a criticality matrix using severity code as one axis and probability level code as the other. For quantitative assessment, modal criticality number is calculated for each failure mode of each item, and item criticality number is calculated for each item. The criticality numbers are computed using the ...
The preferred number of stations depends to some extent on the characteristics of the candidate group being interviewed, though nine interviews per candidate represents a reasonable minimum. [3] The circuit of interview stations should be within sufficiently close quarters to allow candidates to move from interview room to interview room.
In operations research and engineering, a criticality matrix is a representation (often graphical) of failure modes along with their probabilities and severities. Severity may be classified in four categories, with Level I as most severe or "catastrophic"; Level II for "critical"; Level III for "marginal"; and Level IV for "minor".
