The Dean is responsible for the strategic and financial planning of a self-supporting budget, leadership and human resource management of 165 FTE academic and staff personnel, as well as over 800 part-time instructors.The Dean manages a 123,000 square foot facility that accommodates classrooms, staff offices, computer labs, a business center, conference-and-special-events facilities, a 47-room guest residence center, and dining services.

For example, in polygynous animals with sexual size dimorphism, males may have higher reproductive potential than females, although sons may be costlier to produce than daughters (Andersson, 1994; Clutton-Brock, 1991).

I call this the “intrabrood sharing-out” hypothesis and present a graphical model to derive predictions about the relationship between offspring sex and positions within the brood.

The model considers that sibling competition not only produces differences in the mean share of resources among siblings, but it also increases the predictability of the share obtained by high-ranking sibs and decreases the predictability of the share for low-ranking ones.

Consequently, parents should be selected to deal with such a distribution by promoting the conditions to make it more predictable and then adaptively adjust the sex of particular siblings, especially in high-ranking positions within the brood, rather than to modify the sex ratio of the brood as a whole.

In species with sexual reproduction, parents should divide their parental investment into the production of sons and daughters.
