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 />
