A Constructive Characterisation of Circuits in the Simple (2,2)-sparsity Matroid

We provide a constructive characterisation of circuits in the simple (2,2)-sparsity matroid. A circuit is a simple graph G=(V,E) with |E|=2|V|-1 and the number of edges induced by any $X \subsetneq V$ is at most 2|X|-2. Insisting on simplicity results in the Henneberg operation being enough only when the graph is sufficiently connected. Thus we introduce 3 different join operations to complete the characterisation. Extensions are discussed to when the sparsity matroid is connected and this is applied to the theory of frameworks on surfaces to provide a conjectured characterisation of when frameworks on an infinite circular cylinder are generically globally rigid.Comment: 22 pages, 6 figures.

Enrich: improving integration between an institutional repository and a CRIS at the University of Glasgow

This paper provide details of the work and the lessons learned by the JISC funded Enrich project run by the University of Glasgow in the United Kingdom. Enrich provided a clear focus for the integration and enhancement of the University of Glasgow’s repository, Enlighten, with other institutional systems, including our Research System [CRIS] (for funder data) and our Data Vault (for staff records). The Enrich project has demonstrated that partnership between the University Library and the Research Office, in conjunction with researchers, administrators and IT Services is critical to ensuring the successful integration of a repository and a CRIS. Enrich is part of a wider JISC funded programme in the UK: “Information Environment 2009-11” which focuses on the management, discovery and use of information resources. It was completed at the end of March 2010

Beyond the Circle of Life

It seems certain to me that I will die and stay dead. By “I”, I mean me, Greg Nixon, this person, this self-identity. I am so intertwined with the chiasmus of lives, bodies, ecosystems, symbolic intersubjectivity, and life on this particular planet that I cannot imagine this identity continuing alone without them. However, one may survive one’s life by believing in universal awareness, perfection, and the peace that passes all understanding. Perhaps, we bring this back with us to the Source from which we began, changing it, enriching it. Once we have lived – if we don’t choose the eternal silence of oblivion by life denial, vanity, indifference, or simple weariness – the Source learns and we awaken within it. Awareness, consciousness, is universal – it comes with the territory – so maybe you will be one of the few prepared to become unexpectedly enlightened after the loss of body and self. You may discover your own apotheosis – something you always were, but after a lifetime of primate experience, now much more. Since you are of the Source and since you have changed from life experience and yet retained the dream of ultimate awakening, plus you have brought those chaotic emotions and memories back to the Source with you (though no longer yours), your life & memories will have mattered. Those who awaken beyond the death of self will have changed Reality

Breaking Out of One’s Head (& Awakening to the World)

Herein, I review the shattering moment in my life when I awoke from the dream of self to find being as part of the living world and not in my head, discovering my perspectival center to be literally everywhere. Since awakening to the world takes one beyond thought and language thus also beyond the symbolic construction of time, it is strange to place this event and its aftermath as happening long ago in my life. It is forever present. This fact puts into question the reality of my daily journey from dawn to dusk with all the mundane tasks I must complete. My linear march into aging and death inexorably continues, yet it seems somehow unreal, worth a smile as the inevitable changes ensue. Still, I write of the events leading up to my time out of mind and then review the serious repercussions that followed when I was drawn back into ego only to find I did not have the conceptual tools or the maturity to understand what had occurred. I close by looking back with theories that might explain what happened. I am now ready to allow the memory to sink into peaceful oblivion and reference it from within my mind no more. Ironically, the memory itself with its façade of knowledge may prevent me from a new, unexpected mystical experience. Only by forgetting can I hope to leave a crack in the verbal armament of self, so the world soul may break through and free me once again

Heightened Consciousness

Heightened consciousness has become a common expression in daily conversations, but it expresses a number of different concepts depending on the meaning of the speaker and is related to other phrases or terms that have slightly different connotations. This entry explores the different meanings of the term heightened consciousness and similar phrases in regard to personal development

EDUCATION AS MYTHIC IMAGE

Mythopoetry, the imagistic voice of the muses which manifests in myth and natural poetry, has been invoked as an impression of ideal curriculum with which to cherish intimate, vital experience (and to oppose its exile from educational life). In this statement, I intend to see through the pleasant surface of the label, mythopoetry, to see what image may lie just out of sight, beyond the "inspired writing" that mythopoetry implies. Beyond words themselves, meaning is found in sound and in expressive representation. “Music, when soft voices die, / Vibrates in the memory” (Shelley
