Table of Remembrance

(Excerpt) The theme announced for this Institute is Grace upon Grace: Uving Bread. In this keynote address I have been asked to set an ecumenical tone for your conversations about the Eucharist, speaking to how it means for the faithful and drawing upon my own theology-which reviewers, both Lutheran and Evangelical, have dubbed a distinctively Roman Catholic theology but one that is ecumenically open and challenging. I think this means that it opens the way to better mutual understanding and enrichment. Drawing on this theology, I have chosen five headings under which to offer my considerations: the Eucharist as testament of service, the Eucharist as an invitation to table, the Eucharist as a table where memories are stored, the Eucharist as a table where Jesus Christ is guest, host and gift, and the Eucharist as a table of blessing

A postal survey to identify and describe nurse led clinics in genitourinary medicine services across England

Background: Nurses in genitourinary medicine (GUM) services are progressively extending their roles to conduct "comprehensive care" nurse led clinics. In such roles the nurse coordinates the first line, comprehensive care of patients presenting with sexual health conditions and issues. Objectives: To identify and describe comprehensive care nurse led clinics in GUM services across England. Methods: A postal questionnaire consisting of 17 closed response questions was sent to 209 GUM services across England. A second questionnaire was sent to non-responders to increase the response rate. Data were single entered and analysed using SPSS. Results: Of the 190 GUM clinic respondents (91% response rate), 44 (23%) reported providing some form of comprehensive care nurse led clinic, 90% of which were initiated since 1995. Key results show staff development featured as the main reason for initiating such services and there was general consistency in the aspects of care undertaken by these nurses. There was evidence of guideline development specific to nurse led care and some patient group direction use for supplying medication. The level of support from medical staff while nurse led clinics were being conducted varied between services. Few services have conducted any audit or research to monitor/evaluate nurse led care. There was little consistency in the clinical experience and educational prerequisites to undertake comprehensive care nurse led clinics. Continuing professional development opportunities also varied between services. Conclusions: The steady growth of comprehensive care nurse led clinics indicates that the skills of GUM nurses are being recognised. Nurses working in advanced practice roles now require courses and study days reflecting these changes in practice. Locally agreed practice guidelines can define nursing practice boundaries and ensure accountability, as will the development of patient group directions to supply medication. Monitoring and evaluation of nurse led clinics also require attention

Decoherence of quantum wavepackets due to interaction with conformal spacetime fluctuations

One of the biggest problems faced by those attempting to combine quantum theory and general relativity is the experimental inaccessibility of the unification scale. In this paper we show how incoherent conformal waves in the gravitational field, which may be produced by quantum mechanical zero-point fluctuations, interact with the wavepackets of massive particles. The result of this interaction is to produce decoherence within the wavepackets which could be accessible in experiments at the atomic scale. Using a simple model for the coherence properties of the gravitational field we derive an equation for the evolution of the density matrix of such a wavepacket. Following the primary state diffusion programme, the most promising source of spacetime fluctuations for detection are the above zero-point energy fluctuations. According to our model, the absence of intrinsic irremoveable decoherence in matter interferometry experiments puts bounds on some of the parameters of quantum gravity theories. Current experiments give \lambda > 18. , where \lambda t_{Planck} is an effective cut-off for the validity of low-energy quantum gravity theories.Comment: REVTeX forma

Stuck Between ‘the Rock’ and a Hard Place: Re-imagining Rural Newfoundland Feminine Subjectivities Beyond the Global Imaginary and Rural Crisis

There has been a growing body of research exploring the mobility experiences of rural youth as they migrate in search of work, education and leisure. In this paper we contribute to this body of knowledge by examining the mobility experiences of young women (16-24 years) living on the southwest coast of Newfoundland, Canada. In contrast to dominant constructions of rural crisis that position out of the way places as in decline, dying or dead, we argue that the young women in our study articulated complex, affective relations to place. In so doing they negotiated localized histories, prevailing social relations, broader discursive constructions and embodied affective connections in forging their emplaced feminine subjectivities. We argue that foregrounding the complex and at times contradictory relationships that the young women articulated with their rural homes is an important step in prying open dominant albeit constraining constructions of the rural, thereby allowing for alternative and more inhabitable imaginings of out of the way places

Thermohaline mixing in low-mass giants

Thermohaline mixing has recently been proposed to occur in low mass red giants, with large consequences for the chemical yields of low mass stars. We investigate the role of thermohaline mixing during the evolution of stars between 1Msun and 3Msun, in comparison to other mixing processes acting in these stars. We confirm that thermohaline mixing has the potential to destroy most of the ^3He which is produced earlier on the main sequence during the red giant stage. In our models we find that this process is working only in stars with initial mass M <~ 1.5Msun. Moreover, we report that thermohaline mixing can be present during core helium burning and beyond in stars which still have a ^3He reservoir. While rotational and magnetic mixing is negligible compared to the thermohaline mixing in the relevant layers, the interaction of thermohaline motions with differential rotation and magnetic fields may be essential to establish the time scale of thermohaline mixing in red giants.Comment: 6 pages, conference proceedings IAU Symposium 252 (Sanya

A FINANCIAL TRAINING PROGRAM FOR USDA/FSA BORROWERS: EVOLUTION AND IMPACTS

A financial training program designed by Cooperative Extension specialists was provided to over 2,000 USDA/FSA borrowers from the Northeast during the period 1994-1999. Key to the success of the workshops was an in-depth, user friendly curriculum that evolved over time, eventually replacing satellite-feed instruction with pre-taped videos. Cluster analysis classified nearly 70% of workshop participants as "Low Finance Priority" or "Low Finance Knowledge." Farmers in these clusters received a relatively greater educational benefit from the program than those not in these clusters. Impact analysis indicated that perceived annual gain in farm net worth from application of workshop tools ranged from approximately $5,000 to$10,000. The training addressed the needs of producers typically isolated from Cooperative Extension because the workshop was the only extension program attended that year by nearly two-thirds of them.Agricultural Finance,

A semantical approach to equilibria and rationality

Game theoretic equilibria are mathematical expressions of rationality. Rational agents are used to model not only humans and their software representatives, but also organisms, populations, species and genes, interacting with each other and with the environment. Rational behaviors are achieved not only through conscious reasoning, but also through spontaneous stabilization at equilibrium points. Formal theories of rationality are usually guided by informal intuitions, which are acquired by observing some concrete economic, biological, or network processes. Treating such processes as instances of computation, we reconstruct and refine some basic notions of equilibrium and rationality from the some basic structures of computation. It is, of course, well known that equilibria arise as fixed points; the point is that semantics of computation of fixed points seems to be providing novel methods, algebraic and coalgebraic, for reasoning about them.Comment: 18 pages; Proceedings of CALCO 200

Cross-Lingual Classification of Crisis Data

Many citizens nowadays flock to social media during crises to share or acquire the latest information about the event. Due to the sheer volume of data typically circulated during such events, it is necessary to be able to efficiently filter out irrelevant posts, thus focusing attention on the posts that are truly relevant to the crisis. Current methods for classifying the relevance of posts to a crisis or set of crises typically struggle to deal with posts in different languages, and it is not viable during rapidly evolving crisis situations to train new models for each language. In this paper we test statistical and semantic classification approaches on cross-lingual datasets from 30 crisis events, consisting of posts written mainly in English, Spanish, and Italian. We experiment with scenarios where the model is trained on one language and tested on another, and where the data is translated to a single language. We show that the addition of semantic features extracted from external knowledge bases improve accuracy over a purely statistical model

Plasma spray nozzle with low overspray and collimated flow

An improved nozzle for reducing overspray in high temperature supersonic plasma spray devices comprises a body defining an internal passageway having an upstream end and a downstream end through which a selected plasma gas is directed. The nozzle passageway has a generally converging/diverging Laval shape with its upstream end converging to a throat section and its downstream end diverging from the throat section. The upstream end of the passageway is configured to accommodate a high current cathode for producing an electrical arc in the passageway to heat and ionize the gas flow to plasma form as it moves along the passageway. The downstream end of the nozzle is uniquely configured through the methodology of this invention to have a contoured bell-shape that diverges from the throat to the exit of the nozzle. Coating material in powder form is injected into the plasma flow in the region of the bell-shaped downstream end of the nozzle and the powder particles become entrained in the flow. The unique bell shape of the nozzle downstream end produces a plasma spray that is ideally expanded at the nozzle exit and thus virtually free of shock phenomena, and that is highly collimated so as to exhibit significantly reduced fanning and diffusion between the nozzle and the target. The overall result is a significant reduction in the amount of material escaping from the plasma stream in the form of overspray and a corresponding improvement in the cost of the coating operation and in the quality and integrity of the coating itself
