The current leisure trends are encompassed in technology as it becomes more accessible to children in the form of social media platforms or streaming on-demand TV shows. Perhaps there is a way to bring back the importance of nature and intertwine environmental education concepts into teacher preparation programs. In that case, there is hope for future generations of children to reap the …

A Generalized Approach To Partitioning Weighted Points In A Plane, Jacob Denault

Theses and Dissertations

A theorem commonly known as the Discrete Pancake Theorem states that for two finite disjoint sets S and T of points in a plane where the union of S and T contains no three collinear points, there exists a line that simultaneously bisects |S| and |T| within an error of at most one. This thesis considers a more general situation in which each point is assigned two non-negative weights and, instead of simply bisecting the plane to obtain a balance in the number of points, we prove there exists a line that simultaneously balances weight one and weight two accumulations …

Effects Of Corporate Cultural Distance On Private Company M&A Outcomes, Court Carruthers

Theses and Dissertations

Despite nearly $5 trillion of annual global merger and acquisition (M&A) activity, the degree of shareholder value created by M&A remains a topic of debate. The historical view is that M&A does not increase value for acquiring firms, however recent public company financial research suggests that returns are highly variable, rather than uniformly negative. Cultural differences between acquiring and acquired companies, or corporate cultural distance (CCD), are noted as a potential cause of this variability, however, public company findings remain inconclusive. Although private equity (PE) is responsible for approximately 20% of annual M&A transaction value, nearly all prior research is …
