Self-balancing sanctuarying : a grounded theory of relaxation and autogenic training

The purpose of this study was to discover how relaxation in general works, and how components of Autogenic Training (AT) (Luthe and Schultz, 2001), a relaxation therapy, may be working together and separately in an anxiolytic process. A corollary purpose was to develop recommendations for clinical practice. Data consisted of personally and historically collected interviews (n=46) and diaries (n=34). Participants with less than moderate anxiety volunteered from the community at large; and, participants with moderate to severe anxiety were drawn from the Royal London Hospital for Integrated Medicine’s AT Department and British Autogenic Society therapist’s client lists. A classical Glaserian grounded theory analysis methodology was used to determine participants’ main concern (self-balancing) and the way they continually resolved this concern (sanctuarying). The theory of relaxation as a self-balancing sanctuarying process emerged from analysis of what 21 people from the community at large say they do to relax in everyday life. The activities they choose for sanctuarying are self-emergent, and their continuing use is contingent upon managing hindrances and integrating feedback to the process so that the benefits of doing the activity are maximized. Three switching strategies, distracting and blocking, managing and controlling, and letting go and allowing, are central. Benefits which are not consciously or analytically generated are: restoring, refreshing and re-energizing me; maintaining and building me; and growing and developing me. Maintaining and building me are characterized by integrating and strengthening the core self and connecting to the community; growing and developing me is characterized by expanding self-discovery. The theory of self-balancing sanctuarying was used on an emergent fit basis to analyse 25 interviews and 34 diaries gathered from people with symptoms of moderate to severe anxiety whilst learning to practice Autogenic Training. This analysis broadened and deepened the grounded theory. This thesis contributes to knowledge in many areas. It is the first classical grounded theory of relaxation and of Autogenic Training, theoretically situating and/or challenging extant descriptive and conceptual models of both relaxation and AT. It supports the clinically functional equivalence of certain forms of relaxation and supports Teasdale and Barnard’s (1995) Interacting Cognitive Subsystems Model. It supports and challenges certain aspects of core affect theory, of the cognitive appraisal theory of emotions, and of Fredrickson’s (2001, 2003) broaden and build theory of positive emotions. It adds a grounded perspective to the spiritual well-being debate, bringing new knowledge to it. It adds new data to the field of the phenomenology of hypnagogic images. It discusses the implication of Self-balancing Sanctuarying for training of AT therapists and for their clinical practice with anxious clients

Fourier Transform Spectroscopy of the submillimetre continuum emission from hot molecular cores

We have used a Fourier Transform Spectrometer on the James Clerk Maxwell Telescope to study the submillimetre continuum emission from dust in three hot molecular cores (HMC). The spectral index beta of the dust emission for these sources has been determined solely within the 30 GHz wide 350 GHz (850 micron) passband to an accuracy comparable to those determined through multi-wavelength observations. We find an average beta = 1.6, in agreement with spectral indices determined from previous submillimetre observations of these sources and with those determined for HMC in general. The largest single source of uncertainty in these results is the variability of the atmosphere at 350 GHz, and with better sky subtraction techniques we show that the dust spectral index can clearly be determined within one passband to high accuracy with a submillimetre FTS. Using an imaging FTS on SCUBA-2, the next generation wide-field submillimetre camera currently under development to replace SCUBA at the JCMT in 2006, we calculate that at 350 GHz it will be possible to determine beta to +/- 0.1 for sources as faint as 400 mJy/beam and to +/- 0.3 for sources as faint as 140 mJy/beam.Comment: 11 pages, 5 figures, accepted for publication in MNRA

Software for integrated manufacturing systems, part 2

Part 1 presented an overview of the unified approach to manufacturing software. The specific characteristics of the approach that allow it to realize the goals of reduced cost, increased reliability and increased flexibility are considered. Why the blending of a components view, distributed languages, generics and formal models is important, why each individual part of this approach is essential, and why each component will typically have each of these parts are examined. An example of a specification for a real material handling system is presented using the approach and compared with the standard interface specification given by the manufacturer. Use of the component in a distributed manufacturing system is then compared with use of the traditional specification with a more traditional approach to designing the system. An overview is also provided of the underlying mechanisms used for implementing distributed manufacturing systems using the unified software/hardware component approach

Software for integrated manufacturing systems, part 1

For several years, a broad, unified approach to programming manufacturing cells, factory floors, and other manufacturing systems has been developed. It is based on a blending of distributed Ada, software components, generics and formal models. Among other things the machines and devices which make up the components, and the entire manufacturing cell is viewed as an assembly of software components. The purpose of this project is to reduce cost, increase the reliability and increase the flexibility of manufacturing software. An overview is given of the approach and an experimental generic factory floor controller that was developed using the approach is described. The controller is generic in the sense that it can control any one of a large class of factory floors making an arbitrary mix of parts

Dispersion and the electron-phonon interaction in a single heterostructure

We investigate the electron-phonon interaction in a polar-polar single heterostructure through the use of the linear combination of hybrid phonon modes, considering the role of longitudinal optical, transverse optical and interface modes, using a continuum model that accounts for both mechanical and electrical continuity over a heterostructure interface. We discuss the use of other models for such systems, such as the bulk phonon (3DP) and dielectric continuum (DC) models, using previously developed sum-rules to explain the limitations on their validity. We find that our linear combination (LC) model gives an excellent agreement with scattering rates previously derived using the 3DP and DC models when the lattice dispersion is weak enough to be ignored, however, when there is a noticeable lattice dispersion, the LC model returns a different answer, suggesting that interface modes play a much greater part in the scattering characteristics of the system under certain conditions. We also discuss the remote phonon effect in polar/polar heterostructures

Low Mass Stars and Brown Dwarfs around Sigma Orionis

We present optical spectroscopy of 71 photometric candidate low-mass members of the cluster associated with Sigma Orionis. Thirty-five of these are found to pass the lithium test and hence are confirmed as true cluster members, covering a mass range of <0.055-0.3M_{sun}, assuming a mean cluster age of <5 Myr. We find evidence for an age spread on the (I, I-J) colour magnitude diagram, members appearing to lie in the range 1-7 Myr. There are, however, a significant fraction of candidates that are non-members, including some previously identified as members based on photometry alone. We see some evidence that the ratio of spectroscopically confirmed members to photometric candidates decreases with brightness and mass. This highlights the importance of spectroscopy in determining the true initial mass-function.Comment: To appear in the 12th Cambridge Workshop on Cool Stars Stellar Systems and the Su

Hot phonon effects on high field transport in GaN & AlN

We have studied the effects of hot phonons on the high-field transport in GaN & AlN. The dynamics of the non-equilibrium electron-LO phonon system is studied via an ensemble Monte-Carlo code. We find that under steady-state conditions the hot-phonons cause the randomization of the electron momentum and increase their mean energy leading to diffusive heating. Average electron energies of three and two times those in the equilibrium phonon cases are found for GaN and AlN at applied fields of 100 kV/cm and 350 kV/cm respectively. The electron velocity is reduced compared to the case with equilibrium phonons at the lattice temperature. In the transient regime peak velocities reached at overshoot are reduced when non-equilibrium phonons are taken into account

Inverse magnetic catalysis and regularization in the quark-meson model

Motivated by recent work on inverse magnetic catalysis at finite temperature, we study the quark-meson model using both dimensional regularization and a sharp cutoff. We calculate the critical temperature for the chiral transition as a function of the Yukawa coupling in the mean-field approximation varying the renormalization scale and the value of the ultraviolet cutoff. We show that the results depend sensitively on how one treats the fermionic vacuum fluctuations in the model and in particular on the regulator used. Finally, we explore a $B$-dependent transition temperature for the Polyakov loop potential $T_0(B)$ using the functional renormalization group. These results show that even arbitrary freedom in the function $T_0(B)$ does not allow for a decreasing chiral transition temperature as a function of $B$. This is in agreement with previous mean-field calculations.Comment: 13 pages, 5 figure
