    Autogenic regulation training (ART), sickness absence, personal problems, time and the emotional-physical stress of student nurses in general training : a report of a longitudinal field investigation

    A field investigation was carried out with student nurses entering General Training in a School of Nursing.  Autogenic Regulation Training (ART), sickness absence, personal problems, time and their emotional physical  experience was evaluated. Measures used in the study included:The Sickness Absence Record (SAR)The Mooney Problem Checklist (MPC)The Crown-Crisp Experiential Index (CCEI)and The Personal Observations Inventory (POI)Data was collected at different time periods early in their nurse education. The study was carried out to  investigate the effectiveness of ART in providing a method of coping with individual stress. Analyses were made  between and within an ART group of student nurses and a comparison group who did not receive training in  ART. Consideration was also given to individual differences of student nurses in each group.Particular attention was paid to the hypotheses that 1) ART is associated with reduced sickness absence in  student nurses when analysed against a comparison group' of student nurses not trained in ART; and 2) ART is  associated with reduced stress in student nurses when compared with student nurses not trained in ART. 'It  is generally concluded that student nurses trained in ART may reduce their level of sickness absence and can  alleviate stress for some student nurses. However, examination of individual student nurse reports of ART and  its usefulness and practice within these group data, suggest more complex interpretations of the study. Despite  the study limitations, implications for methods of stress control for nurses, curriculum development and  cost-effective savings for nursing administrations are suggested, and possibilities for the development of  comprehensive counselling services for nurses are raised. These issues it is suggested, should be examined within a broader programme of research into coping with stress amongst nurses

    Applications of Ground Penetrating Radar to Structural Analysis of Carbonate Terraces on the Island of Bonaire, Caribbean Netherlands

    This thesis utilized the method of ground penetrating radar to investigate the structural geology of carbonate units in relation to the evolution of the island of Bonaire, Caribbean Netherlands. Two surveys were completed on the island for this purpose: a long continuous cross-island transect, as well as a smaller set of lines that facilitated three-dimensional interpretation at an outcrop known as Seru Grandi. In the detailed processing workflow implemented for the collected datasets, steps were taken to remove unwanted signal noise, and advanced imaging techniques where then applied to generate interpretable subsurface cross-sections. A novel numerical interpretation tool was developed for use on the cross-island transect, which adapted a traditional k-means clustering algorithm for use with structure-parallel vectors derived from structure tensors. The results of this method were utilized in defining a set of radar facies for the cross-island transect. Mapping of these radar facies identified subsurface features related to subtidal-to-foreshore depositional sequences in the southern part of the transect, a potential lagoon system in the south-central portion, eolianites within the center of the transect, and clinoforms related to platform slope deposits in the northeast portions of the survey. Using the small-scale dataset at the Seru Grandi outcrop, subsurface geometries of a previously identified geologic unconformity were described. This unconformity was identified here to be the remnants of a wave cut-platform occurring at the site. The specific geometry of this feature was related to external controls on wave cut-platform development. In addition, the data collected at Seru Grandi identified a set of clinoform surfaces in the subsurface below the mapped unconformity. These observations were compared to previously identified clinoforms observed on the face of the outcrop. Observations and interpretations from both surveys in this study were used to provide additional information relating to the geologic evolution of Bonaire

    Looks are situation-dependent properties

    Get PDF
    This thesis concerns the distinction between appearance and reality. Particularly, the metaphysical nature of a class of visual appearances that I call "looks." I answer the question of what looks are. My positions constitutes a break with philosophical tradition: looks are not minddependent properties, but objective--mind-independent--properties of objects. They are not, however, intrinsic properties, but relational properties objects have of projecting light of a certain informational character to a viewpoint. Looks-properties are instantiated relative to certain of the intrinsic properties of objects, spatial relations between objects and viewpoints, and environmental conditions on which the character of the light at the viewpoint depend.Dr. Matthew McGrath, Thesis Supervisor.Includes bibliographical references (pages 31-32)

    Continuous Generation and Stabilization of Mesoscopic Field Superposition States in a Quantum Circuit

    Full text link
    While dissipation is widely considered as being harmful for quantum coherence, it can, when properly engineered, lead to the stabilization of non-trivial pure quantum states. We propose a scheme for continuous generation and stabilization of Schr\"{o}dinger cat states in a cavity using dissipation engineering. We first generate non-classical photon states with definite parity by means of a two-photon drive and dissipation, and then stabilize these transient states against single-photon decay. The single-photon stabilization is autonomous, and is implemented through a second engineered bath, which exploits the photon number dependent frequency-splitting due to Kerr interactions in the strongly dispersive regime of circuit QED. Starting with the Hamiltonian of the baths plus cavity, we derive an effective model of only the cavity photon states along with analytic expressions for relevant physical quantities, such as the stabilization rate. The deterministic generation of such cat states is one of the key ingredients in performing universal quantum computation.Comment: 9 pages, 6 figure
