g-Elements, finite buildings and higher Cohen–Macaulay connectivity
No full textAbstractChari proved that if Δ is a (d−1)-dimensional simplicial complex with a convex ear decomposition, then h0⩽⋯⩽h⌊d/2⌋ [M.K. Chari, Two decompositions in topological combinatorics with applications to matroid complexes, Trans. Amer. Math. Soc. 349 (1997) 3925–3943]. Nyman and Swartz raised the problem of whether or not the corresponding g-vector is an M-vector [K. Nyman, E. Swartz, Inequalities for h- and flag h-vectors of geometric lattices, Discrete Comput. Geom. 32 (2004) 533–548]. This is proved to be true by showing that the set of pairs (ω,Θ), where Θ is a l.s.o.p. for k[Δ], the face ring of Δ, and ω is a g-element for k[Δ]/Θ, is nonempty whenever the characteristic of k is zero.Finite buildings have a convex ear decomposition. These decompositions point to inequalities on the flag h-vector of such spaces similar in spirit to those examined in [K. Nyman, E. Swartz, Inequalities for h- and flag h-vectors of geometric lattices, Discrete Comput. Geom. 32 (2004) 533–548] for order complexes of geometric lattices. This also leads to connections between higher Cohen–Macaulay connectivity and conditions which insure that h0<⋯<hi for a predetermined i

Book Review: Omar Swartz (Ed.), Communication and Creative Democracy: Interdisciplinary Perspectives
No full textAccording to editor Omar Swartz, the aim of Communication and Creative Democracy: Interdisciplinary Perspectives is to provide “a conceptual framework for understanding what it means to be an engaged citizen” (13). To accomplish this aim, Swartz brings together ten essays from a variety of disciplinary backgrounds that are intended to tease out and further develop the notion of “creative democracy,” an admittedly vague term coming out of the work of John Dewey. However, this is a book one should not read if one is looking to find out more about Dewey and his thought. Yet for those interested in the role of communication in relation to inclusive, democratic spheres, and how its myriad contemporary manifestations might impact the kind of people we are and the sort of world in which we live, then this is a valuable collection of essays to which one might turn

"A fine balance" : a case study of love, hatred and sadomasochism
No full textBibliography: leaves 78-84.This dissertation describes a clinical decision taken to separate an adolescent girl child from her mother and place her in the care of her father. This decision was considered imperative in light of the continued risks posed to the physical and emotional health of the child through continued living with her mother. The mother's combined presentation of hatred and sadomasochism, underlying a borderline personality structure, acted as a powerful obstacle in her being able to love her daughter. Using the theoretical tenets of self psychology to understand the clinical presentation of both mother and daughter, it emerged that the fragmented self-structure of the mother, which had its antecedents in her own traumatic childhood milieu did not permit an interpretive therapeutic approach. Instead work with both the mother and daughter required careful and continuous monitoring, and a flexible clinical stance especially when the therapy itself inadvertently retraumatised the mother. The advantage of the case study, the methodological design employed in this thesis, is that it enabled one to provide an in-depth study of a specific case, especially in light of issues that are considered unusual such as the separation that this intervention demanded. The case study also provided the opportunity to follow the progress of the psychotherapeutic treatment of the child both prior to and after the separation. A detailed discussion of the therapy provides an opportunity to reflect on the issues which informed the decision, the process and the outcome. Reflecting on the theoretical, research and clinical implications of the decision leads to the conclusion that the value of psychoanalytic theory cannot be undermined, especially as it provided the theoretical justification for the decision which has had a helpful outcome for the child concerned
g-Elements of matroid complexes
No full textAbstractA g-element for a graded R-module is a one-form with properties similar to a Lefschetz class in the cohomology ring of a compact complex projective manifold, except that the induced multiplication maps are injections instead of bijections. We show that if k(Δ) is the face ring of the independence complex of a matroid and the characteristic of k is zero, then there is a non-empty Zariski open subset of pairs (Θ,ω) such that Θ is a linear set of parameters for k(Δ) and ω is a g-element for k(Δ)/〈Θ〉. This leads to an inequality on the first half of the h-vector of the complex similar to the g-theorem for simplicial polytopes

Farm ponds of the eastern Great Plains: Key challenges and opportunities for conserving amphibians in these novel ecosystems
No full textFarm ponds are numerous in the agricultural landscapes of the Eastern Great Plains of the United States. These ponds are constructed to support a variety of functions, including erosion control, cattle grazing, and recreational fishing, but their role in supporting native biodiversity, including amphibians, remains poorly understood. In addition, it is unclear how farm ponds fit into existing frameworks of restoration and conservation. Despite their abundance, there are no large-scale initiatives in place to enhance the biodiversity value of farm ponds in the United States. Emerging frameworks like the novel ecosystems concept could provide a path forward for farm pond conservation, but the concept remains controversial and its applicability largely untested.
Consequently, my goal was to address both the ecological and philosophical aspects of farm ponds as refuges for biodiversity in agricultural landscapes. First, I sought to identify the important biophysical components of amphibian breeding habitat in farm ponds and assess the species-specific effects of cattle and fish presence. I then used a chronosequence approach to determine whether pond renovation, which often occurs when ponds are 35 years old, threatens the development of amphibian habitat. I found that farm ponds support amphibian reproduction, but habitat use varied by species, underscoring the importance of species-specific approaches. In addition, pond renovation threatens the development of pH, pond slope, and emergent vegetation conditions predictive of amphibian breeding. Moving forward, it will be important to develop ecological and conceptual approaches to balance the agricultural and biodiversity values of these sites. By enabling us to explicitly acknowledge the anthropogenic nature of farm ponds without disregarding them as ‘degraded’, the novel ecosystems concept provides a framework for articulating the conservation value of these ecosystems.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2020-08-01The student, Timothy Swartz, accepted the attached license on 2018-07-10 at 09:20.The student, Timothy Swartz, submitted this Thesis for approval on 2018-07-10 at 09:21.This Thesis was approved for publication on 2018-07-10 at 15:14.DSpace SAF Submission Ingestion Package generated from Vireo submission #12791 on 2018-09-27 at 11:36:31Made available in DSpace on 2018-09-27T16:47:27Z (GMT).

Another country: everyday social restitution
No full textIn Another Country: Everyday Social Restitution, author Sharlene Swartz introduces the concept of 'social restitution' - understood as the actions and attitudes that everyday people can undertake in dialogue with each other to 'make things good' since 'making things right' is impossible. In setting out an understanding of and an agenda for social restitution, she offers four ideas based on engaged reflection with sixty ordinary South Africans of all ages, colours and classes. First, injustice damages all our humanity and continues over time, and must be understood before we can simply move forward. Second, that a broad understanding of restitution is a helpful tool to bring about change, and that we need new language beyond the labels of victim and perpetrator to talk about our role in the past (such as beneficiary, resister, ostrich, architect or implementer). Third, that restitution should aim at restoring dignity, opportunity, belonging and memory, and so should include not only symbolic but also practical and financial acts. Fourth, that there is something for everyone to do - individuals and communities, alongside government and institutional efforts, and the best way to decide on what action should be taken is to decide together, in dialogue, across previous divides. This book offers stories, ideas and strong theories for how South Africa can be Another Country in our lifetime.
