Packing Steiner Trees

Let $T$ be a distinguished subset of vertices in a graph $G$. A $T$-\emph{Steiner tree} is a subgraph of $G$ that is a tree and that spans $T$. Kriesell conjectured that $G$ contains $k$ pairwise edge-disjoint $T$-Steiner trees provided that every edge-cut of $G$ that separates $T$ has size $\ge 2k$. When $T=V(G)$ a $T$-Steiner tree is a spanning tree and the conjecture is a consequence of a classic theorem due to Nash-Williams and Tutte. Lau proved that Kriesell's conjecture holds when $2k$ is replaced by $24k$, and recently West and Wu have lowered this value to $6.5k$. Our main result makes a further improvement to $5k+4$.Comment: 38 pages, 4 figure

Coordination and Symbolic Convergence at the CANDLES Holocaust Museum and Education Center

Using Coordinated Management of Meaning (CMM) and Symbolic Convergence Theory (SCT), this study examines the ways in which meaning is managed between the messages of the CANDLES Holocaust Museum and Education Center and the visitors of the museum. The research shows that the museum and the museum visitors work together in order to create an overall rhetorical vision of the museum\u27s main message, both within the museum space and beyond. Using the metaphor of conversation, this study demonstrates the three ways through which the museum and its visitors achieve the rhetorical vision: historical conversation, personal conversation, and residual conversation. In order for the rhetorical vision to be created, both the in-group (museum) and the out-group (museum visitors) must participate in the conversations surrounding the overall message of the museum. Practically, this study outlines a base for other museums to analyze how rhetorical visions are or are not functioning within the museum space and with museum visitors

DeLillo\u27s Falling Man and the Trouble with Sympathy in Narratives of Terrorism

In her article DeLillo\u27s Falling Man and the Trouble with Sympathy in Narratives of Terrorism Jessica McDonald discusses the ways Don DeLillo\u27s characterization of a 9/11 terrorist elicits reader sympathy in his 2007 novel Falling Man. McDonald argues that introducing sympathy into narratives of terrorism undermines attempts to understand the contextual issues out of which terrorism arises even if the rhetoric of sympathy may seem to foster a sense of fellow-feeling that makes acts of political protest and resistance more accessible to broader publics
