Research concerning the reciprocal influence of relationships and dementia largely focuses on dyadic relationships despite evidence that whole families are affected. Furthermore, such research generally considers more common forms of dementia such as Alzheimer's disease. Behavioural variant fronto-temporal dementia (bvFTD) primarily although not exclusively affects people below the age of 65 and is distinctly different in its impact from more common forms of dementia, affecting social cognition and therefore relational functioning. We aimed to develop a detailed understanding of intergenerational family experiences of bvFTD over time. We adopted a social constructivist and pluralist approach, using Narrative Thematic Analysis and Grounded Theory. We interviewed seven families in their own homes, including the person with bvFTD, at up to three time-points every six to nine months from 2012 to 2014, resulting in 46 interviews with 19 family members. Three super-ordinate themes were identified: Theme 1: We before bvFTD: cohesive and connected – disconnected and distant; Theme 2: Challenges experienced by us; and Theme 3: Relational outcomes: a changing we – an entrenched we. Results emphasise bvFTD brought early and significant disruption to family relationships. The interplay of prior relational functioning, involving the nature of the relationship for family members, the specific impact of bvFTD on these relationships and family member's understanding of bvFTD was critical to how each family fared over the duration of the research, and the relational outcomes they experienced. These findings suggest health-care practice could enhance its support for families living with bvFTD, through the development of tailored, family-oriented approaches to assessment and practice. Such approaches are necessary to understand how families work together and identify interventions that address the family-specific challenges bvFTD brings. The provision of tailored, relational-focused and specialised information concerning the experience of living with bvFTD is needed to flexibly address families' needs and expectations.

Organisational culture of institutions providing care for older people is increasingly recognised as influential in the quality of care provided. There is little research, however, that specifically examines the processes of care home culture and how these may be associated with quality of care. In this paper we draw from an empirical study carried out in the United Kingdom (UK) investigating the relationship between care home culture and residents' experience of care. Eleven UK care homes were included in an in-depth comparative case study design using extensive observation and interviews. Our analysis indicates how organisational cultures of care homes impact on the quality of care residents receive. Seven inter-related cultural elements were of key importance to quality of care. Applying Schein's conceptualisation of organisational culture, we examine the dynamic relationship between these elements to show how organisational culture is locally produced and shifting. A particular organisational culture in a care home cannot be achieved simply by importing a set of organisational values or the ‘right’ leader or staff. Rather, it is necessary to find ways of resolving the everyday demands of practice in ways that are consistent with espoused values. It is through this everyday practice that assumptions continuously evolve, either consistent with or divergent from, espoused values. Implications for policy makers, providers and practitioners are discussed.

This article addresses gaps in definitions and a lack of standard measurement techniques to assess the spatial resolution in atom probe tomography. This resolution is known to be anisotropic, being better in-depth than laterally. Generally the presence of atomic planes in the tomographic reconstruction is considered as being a sufficient proof of the quality of the spatial resolution of the instrument. Based on advanced spatial distribution maps, an analysis methodology that interrogates the local neighborhood of the atoms within the tomographic reconstruction, it is shown how both the in-depth and the lateral resolution can be quantified. The influences of the crystallography and the temperature are investigated, and models are proposed to explain the observed results. We demonstrate that the absolute value of resolution is specimen specific.

Drag-reduction experiments with combined injection of high-molecular-weight long-chained polymers and microbubbles were conducted on a 3.1 m long flat plate model in the 1.22 m diameter water tunnel at the Applied Research Laboratory of the Pennsylvania State University. Combined gas injection upstream of polymer injection produced, over a wide range of test conditions, higher levels of drag reduction than those obtained from the independent injection of polymer or microbubbles alone. These increased levels of drag reduction with combined injection were often greater than the product of the drag reductions obtained by the independent constituents, defined as synergy. We speculate that the synergy is a result of the gas-layer-induced extension of the polymer-alone initial diffusion zone in combination with the increased drag reduction by microbubbles. This increased length of the initial zone layer, consistent with high drag reduction, can significantly increase the persistence of the drag reduction and may improve the outlook for practical application.

Highly ordered gold NC/silica films are synthesized by self-assembly of water-soluble gold nanocrystal micelles and soluble silica using a sol-gel spin-coating technique. The optical properties are analyzed using ellipsometry and ultraviolet-visible spectroscopy. The absorption spectra show a strong surface plasmon absorption band at ∼520 nm for all samples. Angular excitation spectra of the surface plasmon show a steep dip in the reflectivity curve at ∼65°. Charge transport behavior of the films is examined using metal-oxide-semiconductor (MOS) structures.MOS capacitor samples exhibit charge storage with discharge behavior dominated by electron transport within the gold NC arrays.
