Patterns Of Interaction

Congregational singing has become problematized within the emerging-church movement. This movement is a self-consciously postmodern expression of Christianity that brings into question not only ideas of group singing but also of the congregation itself, intentionally deconstructing the boundaries, patterns, and norms that have typically served to define the congregational group. Nevertheless, music and sound remain important, if contested, components of emerging-church practices. Through fieldwork undertaken in a number of emerging-church groups, this chapter investigates the ways in which sonic material is deployed in nontraditional settings, and the different patterns of interaction that are set up between agents, spaces, and objects in these environments. In particular, this chapter draws attention to a move away from totalizing patterns of high-intensity resonant union, toward models that, in a variety of different ways, offer space for individuals to experience their own micro-resonant interactions as they engage in a range of different devotional activities.

AbstractThe dynamical interactions of planetary systems may be a clue to their formation histories. Therefore, the distribution of these interactions provides important constraints on models of planet formation. We focus on each system's apsidal motion and proximity to dynamical instability. Although only ∼25 multiple planet systems have been discovered to date, our analyses in these terms have revealed several important features of planetary interactions. 1) Many systems interact such that they are near the boundary between stability and instability. 2) Planets tend to form such that at least one planet's eccentricity periodically drops to near zero. 3) Mean-motion resonant pairs would be unstable if not for the resonance. 4) Scattering of approximately equal mass planets is unlikely to produce the observed distribution of apsidal behavior. 5) Resonant interactions may be identified through calculating a system's proximity to instability, regardless of knowledge of angles such as mean longitude and longitude of periastron (e.g. GJ 317 b and c are probably in a 4:1 resonance). These properties of planetary systems have been identified through calculation of two parameters that describe the interaction. The apsidal interaction can be quantified by determining how close a planet is to an apsidal separatrix (a boundary between qualitatively different types of apsidal oscillations, e.g. libration or circulation of the major axes). This value can be calculated through short numerical integrations. The proximity to instability can be measured by comparing the observed orbital elements to an analytic boundary that describes a type of stability known as Hill stability. We have set up a website dedicated to presenting the most up-to-date information on dynamical interactions: http://www.lpl.arizona.edu/~rory/research/xsp/dynamics.

Experiments with real photons have been performed for many years at the Mainz accelerator MAMI with different detectors. The upgraded MAMI C accelerator recently delivered electrons with an energy of 1604MeV. The A2 collaboration performs experiments with energy tagged polarised real photons produced via 'Bremsstrahlung'. Linear and circular photon polarisation is possible. In the years 2005/2006 the Crystal Ball detector with its unique detection capability for multi photon final states was set up in Mainz. The Crystal Ball at MAMI setup offers an excellent possibility to study decays of the η and η′ mesons. Due to the high intensity photon beam the apparatus can be seen as an η-factory. Recent results from the Crystal Ball experiment at MAMI are presented. In the future we plan to use a longitudinal and transverse polarised frozen spin target to investigate the spin polarisibilities of the nucleons.

Networked Individualism

This chapter offers a contribution to the ongoing research into networked individualism in late modern society from the perspective of religion online. Using a sample of weblogs created by Australians involved in the “emerging church movement,” this chapter will explore how the Internet has enabled individuals to seek relationships with others and discern a religious identity beyond the confines of local faith communities and denominational institutions. Here we will see how those who use blogs to form religious networks must negotiate constructions of communal identities, not just offline, but within the blogosphere. These negotiations represent a postmodern quest for authentic religious expression and practice, which is found in the flow of information among a myriad of traditional and new sources.

Theological Thinking

For about ten years (1998-2008), Kester Brewin was one of the principal instigators of the Vaux community, a ‘vehicle for exploring radical theological thought and practice’. From these experiences and events, he wrote The Complex Christ: Signs of Emergence in the Urban Church (2004). Since then he moved on as a blogger, columnist, tedx-er, and writer. In 2016 he published Getting High: A Savage Journey to the Heart of the Dream of Flight with Vaux Publishing. Getting High is a fascinating reflection on an era dominated by the flight of technology (from the 1960s on), substituting for the eternal longing for the ultimate. But it is also a moving introspection into Brewin’s own life. Being the son of a preacher man, he was getting high on evangelical ecstasy as a young adult, before he became one of the influential figures in the emerging church movement. He ended up, however, ‘outside of what would be taken as orthodox belief.’ This paper discusses Kester Brewin’s ‘piratic’ thoughts on the church, based on his books, blogs, and columns. How did his ‘theological’ thinking evolve, and what does it mean for ecclesiology?

Based on the results of the preliminary study on the influence of high intensity Nd: YAG laser radiation on grinding wheel constituents, an experimental set-up for dressing a grinding wheel was made. Studies were carried out to evaluate the performance of a laser dressed Al2O3 wheel in surface grinding under dry cutting conditions. Results confirmed the viability of this approach and indicated the existence of an optimal dressing condition for good results.

The Introduction to this volume explores the importance of individual–world interactions through the medium of sound in distinguishing between different traditions of Christian worship. I introduce ideas of musicking and resonance and suggest their potential usefulness in exploring the different patterns of interaction present in musical acts of devotion. I draw attention to resonance’s ability to point toward the simultaneous or subsequent sounding of energy in and between multiple actors, entities, and spaces, and to its particular conceptual advantages and strengths in approaching congregational singing. I highlight its ability to foreground the materiality of music while simultaneously giving conceptual space for the overtones latent within and surrounding such materiality. Alongside this, it is able to offer a relatively loose sense of priority that evokes very strongly complex dynamics of interplay back and forth between numerous agents, spaces, things, and materials as energy and vibration are passed between them.
