“We deal here with grey”: a grounded theory of professional boundary development in a forensic inpatient service.

Background: The question of how to maintain appropriate professional boundaries with clients in mental health settings can be complex, particularly for forensic inpatient nurses and healthcare workers. The literature in this area to date has mainly focused on boundary violations with little research on how staff members develop and maintain boundaries in forensic inpatient units, despite safe working relationships being beneficial for staff experience and client recovery. Method: Interviews with eleven psychiatric nurses and healthcare workers from forensic inpatient wards were analysed using a grounded theory methodology. Results: A cyclical model of boundary development was developed in which staff initially acclimatize to the forensic environment using their existing experiences and personal values before entering a calibration phase, where they constantly assess and address professional boundary issues in the course of their daily responsibilities. Staff members use this experience alongside reflection, social learning and clinical supervision to undergo individual learning and team development. In the fourth phase, staff members use this learning to recalibrate their views on boundaries, themselves and how they work with clients. This recalibration impacts on staff members’ further management of daily boundaries providing more material for learning, which leads to further recalibration. Conclusions: This study echoes previous literature suggesting the importance of supervision and reflective spaces in professional boundary understanding. The model is comparable to existing learning theory and highlights the importance of social and experiential learning. There are implications for forensic psychiatric nurses in terms of training, team building, supervision and provision of reflective spaces

Enhanced image annotations based on spatial information extraction and ontologies

Current research on image annotation often represents images in terms of labelled regions or objects, but pays little attention to the spatial positions or relationships between those regions or objects. To be effective, general purpose image retrieval systems require images with comprehensive annotations describing fully the content of the image. Much research is being done on automatic image annotation schemes but few authors address the issue of spatial annotations directly. This paper begins with a brief analysis of real picture queries to librarians showing how spatial terms are used to formulate queries. The paper is then concerned with the development of an enhanced automatic image annotation system, which extracts spatial information about objects in the image. The approach uses region boundaries and region labels to generate annotations describing absolute object positions and also relative positions between pairs of objects. A domain ontology and spatial information ontology are also used to extract more complex information about the relative closeness of objects to the viewer

Mass of \u3csup\u3e18\u3c/sup\u3eMg(g.s.)

We use a potential model, together with spectroscopic factors from a combination of weak coupling and a shell-model calculation, to compute the mass of the ground state of 18Mg, considered as a mirror of 18C. The result is E2p=3.87(10)MeV

Excited states of \u3csup\u3e19\u3c/sup\u3eMg

We have calculated energies of the first two excited states of 19Mg by using a model that was previously successful for the ground state. Computed excitation energies are 1.12 and 1.54 MeV for (3/2−) and (5/2−), respectively—somewhat in disagreement with values of 1.38 and 2.14 MeV from a recent experiment

Matter Radii of \u3csup\u3e29-35\u3c/sup\u3eMg

We have computed matter radii for the ground states of 29–35Mg for a variety of reasonable assumptions about the structure of the relevant states. For cases in which the dominant configuration is generally agreed, our computed radii are in good agreement with experimental ones. For cases in which the dominant configuration is unknown or ambiguous, comparisons between the calculated and experimental Rm do not allow a decision as to the preferred configuration

Predictions for the first two positive-parity states of \u3csup\u3e13\u3c/sup\u3eF

We have used a potential model, together with information from 13Be, to compute expected energies and widths for the first two positive-parity states of 13F. Results are (all in MeV) Ep = 2.30 and 4.94 (or 5.26), width ∼0.6 and 0.3 (or 0.4), for 1/2+ and 5/2+, respectively

Continuum three-body decays of \u3csup\u3e9\u3c/sup\u3eBe(5/2\u3csup\u3e−\u3c/sup\u3e)

We describe and discuss various three-body decay mechanisms for 9Be(5/2−). We find that its decay to n+ 8Be(2+) is a small fraction of the total decay

Entanglement and the Thermodynamic Arrow of Time

We discuss quantum entanglement in the context of the thermodynamic arrow of time. We review the role of correlations in entropy-decreasing events and prove that the occurrence of a transformation between two thermodynamic states constitutes a new type of entanglement witness, one not defined as a separating plane in state space between separable and entangled states, but as a physical process dependent on the local initial properties of the states. Extending work by Partovi, we consider a general entangled multipartite system that allows large reversals of the thermodynamic arrow of time. We describe a hierarchy of arrows that arises from the different correlations allowed in a quantum state and examine these features in the context of Maxwell's Demon. We examine in detail the case of three qubits, and also propose some simple experimental demonstrations possible with small numbers of qubits.Comment: 10 pages with 9 figure

Development of a Procedure to Identify Aggregates for Bituminous Surfaces in Indiana

Adequate friction resistance is needed to prevent pavement slipperiness allowing vehicles to stop in a reasonable distance. For stone mastic asphalt surfaces, friction resistance is mainly a function of the interaction between the aggregates exposed at the road surface and vehicle tires. Aggregate performance is reduced with time by wear and polishing as a consequence of vehicular traffic. In this research a method to investigate performance based on physical, chemical and petrographic factors has been evaluated. The objective was to develop a laboratory method to test Indiana dolomite, limestone, sandstone, and gravel aggregates to predict friction resistance in the field and determine causes for the range of values among these aggregates. Assessment of gravel sources was based on individual rock types and their proportions comprising the gravel. Initial friction Values (IFV) and Polished Values (PV) were determined in the laboratory with the British Wheel and Pendulum test and field values obtained from the towed friction trailer. For two laboratories involved a significant difference in IFV and PV was obtained so that further verification is required. Correlations between parameters were established which provide predictions of friction resistance based on laboratory specimens. A database of physical and chemical properties should be collected on aggregates used or considered for bituminous wearing courses. This includes the testing required for Class A aggregates plus elemental Mg and elemental Ca content
