A new and distinct cultivar of Schefflera plant named \u2018Norma Jean\u2019, characterized by its upright, outwardly spreading and mounded plant habit; short internodes; dense and bushy growth habit; broadly elliptic-shaped leaves; developing leaves with green and yellow green-colored variegation; and fully expanded leaves with darker green and light yellow green-colored variegation. More particularly, this invention relates to intraocular lenses that have the ability to alter the light refractive power in response to changes in the tension of the ciliary muscle or ciliary body of the eye or any other accommodative forces. The cutting block comprises a steel body with a cylindrical barrel holding a cylindrical spring block, to which is mounted a blade holder carrying an elongate blade. If so, an announcement of the incoming call is prevented and a predetermined message is autonomously transmitted to the sender. The threshold value associated with each call type is dynamically adjusted during call center operation based on the fraction of the target service level for a call type being achieved by the call center.
