Abstract

Understanding the flow of multi-phase (melt, crystals and bubbles) magmas is of great importance for interpreting eruption dynamics. Here we report the first observation of crystal plasticity, identified using electron backscatter diffraction, in plagioclase in andesite dome lavas from Volcán de Colima, Mexico. The same lavas, deformed experimentally at volcanic conduit temperature and load conditions, exhibit a further, systematic plastic response in the crystalline fraction, observable as a lattice misorientation. At higher stress, and higher crystal fraction, the amount of strain accommodated by crystal plasticity is larger. Crystal plastic distortion is highest in the intact segments of broken crystals, which have exceeded their plastic limit. We infer that crystal plasticity precludes failure and can punctuate the viscous-brittle transition in crystal-bearing magmas at certain shallow magmatic conditions. Since crystal plasticity varies systematically with imposed conditions, this raises the possibility that it may be used as a strain marker in well-constrained systems., The rheological behaviour of magma in shallow conditions may help determine a volcano’s eruptive style. Here, the authors perform deformation experiments on lava from Volcán de Colima to demonstrate that crystal plasticity may preclude failure at certain shallow magmatic conditions.

Abstract

Albite is one of the most common minerals in the Earth's crust, and its polymorphs can be found in rocks with different cooling histories. The characteristic spectrum of vibration of the albite mineral reflects its structural Si/Al ordering. In this study, we report on the comparison between the Raman spectra measured on a natural and fully ordered (as deduced on the basis of single-crystal X-ray diffraction data) 'low albite', NaAlSi3O8, and those calculated at the hybrid Hartree-Fock/density functional theory level by employing the WC1LYP Hamiltonian, which has proven to give excellent agreement between calculated and experimentally measured vibrational wavenumbers in silicate minerals. All the 39 expected Ag modes are identified in the Raman spectra, and their wavenumbers and intensities, in different scattering configurations, correspond well to the calculated ones. The average absolute discrepancy |Δv¯| is ∼3.4 cm-1, being the maximum discrepancy |Δv|max ∼ 10.3 cm-1. The very good quality of the WC1LYP results allows for reliable assignments of the Raman features to specific patterns of atomic vibrational motion.

186. Shared decision-making in dementia care planning: barriers and facilitators in two European countries

Author

Mariani, E., Vernooij-Dassen, M.J.F.J., Koopmans, R.T., Engels, Y., Chattat, R., Mariani, E., Vernooij-Dassen, M.J.F.J., Koopmans, R.T., Engels, Y., and Chattat, R.

Abstract

Item does not contain fulltext, BACKGROUND: Shared decision-making (SDM) is a means of allowing people with dementia to take part in making choices, be autonomous and participate in social activities. Involving them in SDM is an important way of promoting social health. However, including families and dementia residents in decision-making can be challenging for care staff working in nursing homes. The objective of this study was to identify barriers and facilitators regarding the implementation of an SDM framework for care planning in two nursing homes, one in Italy and one in the Netherlands. METHODS: Focus group interviews were conducted with healthcare professionals who, after being trained, applied the SDM framework. Content analysis was used to analyze the data. RESULTS: Six months after the feasibility trial, focus group interviews with healthcare professionals (n = 10 in Italy; n = 9 in the Netherlands) were held. We found 6 themes and 15 categories. Within these themes, facilitators and barriers were identified. The categories of team collaboration, communication skills and nursing home policy were found to be facilitators to the implementation process, whereas regulations, lack of funding and of involvement of family caregivers were the main barriers. Family attitudes towards SDM could be both. The main difference between countries concerned the residents' cognitive status that influenced their degree of involvement. CONCLUSION: Communication skills training for professionals, training of family caregivers, and involvement of the management in the implementation process seem to be crucial factors in successfully implementing SDM in nursing homes, and increasing the involvement of families and dementia residents in decision-making.

187. Care Plan Improvement in Nursing Homes: An Integrative Review

Abstract

Item does not contain fulltext, BACKGROUND: Care planning nowadays is a key activity in the provision of services to nursing home residents. A care plan describes the residents' needs and the actions to address them, providing both individualized and standardized interventions and should be updated as changes in the residents' conditions occur. OBJECTIVE: The aim of this review was to identify the core elements of the implementation of changes in nursing homes' care plans, by providing an overview of the type of stakeholders involved, describing the implementation strategies used, and exploring how care plans changed. METHODS: An integrative literature review was used to evaluate intervention studies taking place in nursing homes. Data were collected from PubMed, CINHAL-EBSCO, and PsycINFO. English language articles published between 1995 and April 2015 were included. Data analysis followed the strategy of Knafl and Whittemore. RESULTS: Twenty-six articles were included. The stakeholders involved were professionals, family caregivers, and patients. Only a few studies directly involved residents and family caregivers in the quality improvement process. The implementation strategies used were technology implementation, audit, training, feedback, and supervision. The majority of interventions changed the residents' care plans in terms of developing a more standardized care documentation that primarily focuses on its quality. Only some interventions developed more tailored care plans that focus on individualized needs. CONCLUSION: Care plans generally failed in providing both standardized and personalized interventions. Efforts should be made to directly involve residents in care planning and provide professionals with efficient tools to report care goals and actions in care plans.

191. In-situ measurement of texture development rate in CaIrO₃ post-perovskite

Author

Hunt, SA, Walker, AM, and Mariani, E

Abstract

The rate of crystallographic preferred orientation (CPO) development during deformation of post-perovskite is crucial in interpreting seismic anisotropy in the lowermost mantle but the stability field of MgSiO3 post-perovskite prevents high-strain deformation experiments being performed on it. Therefore, to constrain the rate of CPO development in post-perovskite, we deformed CaIrO3, a low-pressure analogue of MgSiO3 post-perovskite, in simple shear at 3.2GPa and 400○C to a shear strain (γ) of 0.81. From X-ray diffraction patterns acquired during deformation, we invert for CPO as a function of strain. By comparing the CPO that develops with visco-plastic self-consistent (VPSC) models we constrain the critical resolved shear stresses (CRSS) of the non-primary slip-systems in CaIrO3 to be of order 6 times stronger than the primary [100](010) slip system. This value is significantly less than has been assumed by previous studies and if applicable to MgSiO3 implies that seismic anisotropy in the D′ layer develops slower than has previously been assumed.
