the self, such as self-efficacy, psychological well-being,<br />

perceived stress and depression. Fifty individuals who<br />

had experienced domestic violence and were currently<br />

staying at a large domestic violence shelter filled out four<br />

standard self-report measures for self-efficacy, psychological<br />

well-being, perceived stress and depression as well as<br />

the newly developed safety scale. Results are expected to<br />

show that there is a positive correlation between safety<br />

and self-efficacy and between safety and psychological<br />

well-being. There is also an expectation of a negative correlation<br />

between safety and perceived stress and between<br />

safety and depression. If the expected results are found,<br />

then it can be inferred that the level of safety an individual<br />

feels is important to other aspects of how the individual<br />

perceives and copes with life. This study can highlight<br />

aspects of safety in which those who have experienced<br />

domestic violence may need support in order to decrease<br />

the negative mental health effects associated with domestic<br />

violence. A scale that can accurately measure the construct<br />

of safety will also be beneficial in determining the optimal<br />

level of safety for those who have experienced domestic<br />

violence to function independently.<br />

3D Morphometrics of the Cercopithecoid Distal<br />

Humerus: Implications for the Reconstruction of<br />

Paleohabitats<br />

The reconstruction of paleohabitats is a necessary<br />

precursor to understanding the environmental pressures that<br />

drove hominin evolution. However, the relative scarcity of<br />

hominins in the fossil record, as compared to other mammals,<br />

makes direct inference difficult. The ecomorphology<br />

of cercopithecoids (Old World monkeys) can serve<br />

as a valuable indicator of habitat composition given their<br />

behavioral diversity and greater relative abundance in Plio-<br />

Pleistocene fossil assemblages. By identifying reliable correlations<br />

between bone morphology and behavior in living<br />

cercopithecoid species, the behavior of extinct species and,<br />

subsequently, the types of environments they inhabited can<br />

be predicted. The morphology of the distal humerus—which<br />

comprises the top half of the elbow joint—is functionally<br />

informative regarding the extent to which the elbow is<br />

adapted for certain types of motion that correspond to the<br />

degree of terrestriality (ground-living) versus arboreality<br />

(tree-living) of a species. This study utilizes geometric<br />

morphometric analyses to visualize 3D shape variation of<br />

the distal humerus among terrestrial, semi-terrestrial and<br />

arboreal cercopithecoids. Humeral shape is digitized using<br />

18 landmarks and analyzed in conjunction with quantitative<br />

behavioral data. Multivariate analyses of coordinate data<br />

are used to determine the accuracy with which individuals<br />

can be placed along a terrestrialarboreal spectrum based<br />

on the morphology of this joint surface. Results show a<br />

significant correlation between distal humeral shape and<br />

percentage of terrestriality, t (26)<br />
