Managerial culture is the values of the management, and its norms, practices and artifacts.
Situational Leadership is one of several two-factor leadership theories or models that emerged starting in the mid-1940s [4] and continuing through the 1960s, which also include Blake and Mouton's Managerial Grid, William James Reddin's 3D Theory, Herzberg's Two-factor theory, and others. In the late 1970s/ early 1980s, Hersey and Blanchard ...
Fractional ownership offers an individual or company the option to purchase a share of an aircraft. Shares from as little as 1/16 of an aircraft, which offers approximately 37.5 hours of flight time per year, to 1/2 of an aircraft can be purchased, depending on the needs of the operator.

In mathematical finance, the Cox–Ingersoll–Ross (CIR) model describes the evolution of interest rates. It is a type of "one factor model" (short-rate model) as it describes interest rate movements as driven by only one source of market risk. The model can be used in the valuation of interest rate derivatives.
s 1 = 0; run the simulation for the first time, producing result r 1; m 1 = r 1; //m i is the mean of the first i simulations for i = 2 to k do run the simulation for the i th time, producing result r i; δ i = r i - m i-1; m i = m i-1 + (1/i)δ i; s i = s i-1 + ((i - 1)/i)(δ i) 2; repeat s 2 = s k /(k - 1);
