Symmetric colorings of polypolyhedra
Polypolyhedra (after R. Lang) are compounds of edge-transitive 1-skeleta.
There are 54 topologically different polypolyhedra, and each has
icosidodecahedral, cuboctahedral, or tetrahedral symmetry, all are realizable
as modular origami models with one module per skeleton edge. Consider a
coloring in which each edge of a given component receives a different color,
and where the coloring (up to global color permutation) is invariant under the
polypolyhedron's symmetry group. On the Five Intersecting Tetrahedra, the edges
of each color form visual bands on the model, and correspond to matchings on
the dodecahedron graph. We count the number of such colorings and give three
proofs. For each of the non-polygon-component polypolyhedra, there is a
corresponding matching coloring, and we count the number of these matching
colorings. For some of the non-polygon-component polypolyhedra, there is a
corresponding visual-band coloring, and we count the number of these band
colorings
Imagining New Possibilities Through Social Practice
In my practice, I have significantly questioned the role of the arts in social change. I have explored various forms of social practice, especially political art,public art and community art. Social practice lives in-between the world of art and social action and can add an important voice to both. Still, social practice, (like all forms of art) is limited and cannot be the sole source of social change. It is by working with others already organizing for social change, but bringing in the unique skills and perspectives of an artist that social practice is most effective. In this thesis, I will be exploring the intentions, impacts and value of public, political and community art. I will look to artists working in each of these ways as examples to understand what makes social practice effective and valuable to larger social movements. Ultimately, I will use this discussion to identify the role of an artist contributing to social change, citing specifically artists’ ability to invite people into the process of imagining alternate possibilities
What’s the Deal With Junie?: Responses from Second and Third Graders to Junie B. Jones
This study examined what children noticed from the Junie B. Jones popular culture series through the use of a book club. The two books read were Junie B. Jones Is Not a Crook (Park, 1997) and Cheater Pants (Park, 2003). Semi-structured and open-ended questions were utilized to gather data. Then, the participants collaboratively created a script based on one of the books. All six sessions were videotaped so that I could review them for accurate data collection.
The children shared many comments throughout the sessions. Generally, the comments indicated that Junie’s language did not always sound “right,” and the children knew better than to behave like her for fear of doing something wrong or receiving negative consequences from an adult or peer. The participants stated that Junie’s language errors and unacceptable behaviors made the book funny. The children often suggested more acceptable behaviors.
An abundance of evidence led to three conclusions. First, children notice and are critical of Junie B. Jones’s language errors while reading books from the Junie B. Jones series written by Barbara Park. Second, children notice and are critical of Junie B. Jones’s inappropriate behaviors while reading books from the Junie B. Jones series. Finally, children are engaged and utilize reading skills while reading popular culture literature.
Students can become better readers if they are given a choice to read popular culture books in school. Also, when students read and discuss popular culture books in book clubs, the students can expand their thinking and further develop their literacy skills. My findings lead me to consider the use of popular culture in student-selected reading and literacy instruction to be beneficial
Predictive habitat modelling as a tool to assess the change in distribution and extent of an OSPAR priority habitat under an increased ocean temperature scenario:consequences for marine protected area networks and management
The aims of this study were to determine the extent and distribution of an OSPAR priority habitat under current baseline ocean temperatures; to illustrate the prospect for habitat loss under a changing ocean temperature scenario; and to demonstrate the potential application of predictive habitat mapping in "future-proofing" conservation and biodiversity management. Maxent modelling and GIS environmental envelope analysis of the biogenic bed forming species, Modiolus modiolus was carried out. The Maxent model was tested and validated using 75%/25% training/test occurrence records and validated against two sampling biases (the whole study area and a 20km buffer). The model was compared to the envelope analysis and the area under the receiver operating characteristic curve (Area Under the curve; AUC) was evaluated. The performance of the Maxent model was rated as 'good' to 'excellent' on all replicated runs and low variation in the runs was recorded from the AUC values. The extent of "most suitable", "less suitable" and "unsuitable" habitat was calculated for the baseline year (2009) and the projected increased ocean temperature scenarios (2030, 2050, 2080 and 2100). A loss of 100% of "most suitable" habitat was reported by 2080. Maintaining a suitable level of protection of marine habitats/species of conservation importance may require management of the decline and migration rather than maintenance of present extent. Methods applied in this study provide the initial application of a plausible "conservation management tool"

Report from the International Clinical Librarian Conference, University of Edinburgh, 10-12 June 2015, Edinburgh
The EAHIL Workshop provided an opportunity for the International Clinical Librarian Conference (ICLC) to run a satellite conference before the official opening of the Workshop. ICLC aim to hold bi-annual conferences either stand alone, or in collaboration with another meeting. Aimed at those with an interest in clinical or outreach librarianship the 2015 ICLC welcomed a range of presentations on this field of the work
Finding Latent Groups in Observed Data: A Primer on Latent Profile Analysis in Mplus for Applied Researchers
The present guide provides a practical guide to conducting latent profile analysis (LPA) in the Mplus software system. This guide is intended for researchers familiar with some latent variable modeling but not LPA specifically. A general procedure for conducting LPA is provided in six steps: (a) data inspection, (b) iterative evaluation of models, (c) model fit and interpretability, (d) investigation of patterns of profiles in a retained model, (e) covariate analysis, and (f) presentation of results. A worked example is provided with syntax and results to exemplify the steps
PRE-ALLEGHANIAN EXTENSION AND POST-ALLEGHANIAN BRITTLE DEFORMATION IN THE SOUTHERN APPALACHIANS
Thrust faults related to the orogenic events that formed the Appalachians dominate the Blue Ridge province in western North Carolina, but no clear extensional faults have beenidentified. We discovered the first documented pre-Alleghanian normal fault within the southern Appalachian Blue Ridge, the Grassy Creek fault (GCf). The GCf may be associated with synorogenic or pre-collisional extension and may also explain the exhumation of an eclogite facies terrane within the Ashe Metamorphic Suite.A set of topographic lineaments in western North Carolina cut the Paleozoic structures and do not correspond with the well-documented geologic history of the southern Appalachians. One of these lineaments corresponds to the Boone fault, which likely accommodates Miocene uplift of the southern Appalachians. We performed fracture and paleostress analyses along lineaments north of the Boone fault, which indicate that they are likely fracture controlled and related to the same deformation event responsible for the Boone fault.Master of Scienc
