    What do we know about the attitudes, experiences and needs of Black and minority ethnic carers of people with dementia in the United Kingdom? A systematic review of empirical research findings

    Get PDF
    This paper reviews recent literature on the experiences, attitudes and needs of caring for someone with dementia in Black and minority ethnic communities in the United Kingdom. Eight articles, which investigated carer experiences from Black and minority ethnic communities when caring for someone with dementia, were critically appraised. All eight studies used a qualitative methodology. The review identified several themes and issues across the qualitative studies. These included memory loss being viewed as a normal process of ageing, care being perceived as an extension of an existing responsibility, a poor understanding of what support services provide, the influence of migration, the impact of stigma and increased female responsibility. Methodological limitations of the research literature studies are also highlighted and clinically relevant implications are discussed, alongside recommendations for future research in this area

    Experiences of cognitive behavioural therapy formulation in clients with depression

    Get PDF
    AbstractWhile clinicians have described the benefits of using formulations within therapy, little is understood about the client's experience of the formulation process. Cognitive behaviour therapy (CBT) is currently the treatment of choice for many adult mental health difficulties. However, research exploring clients’ experiences of CBT formulation is very limited. The present study set out to explore experiences of CBT formulation in clients with depression. Seven participants were interviewed and the data analysed using Thematic Analysis. The analysis identified key themes such as: ‘Feeling trapped or restricted by depression’, ‘The development of the formulation – from coming to my own conclusions to something the therapist developed’, ‘From negative to mixed feelings: emotional reactions to the formulation during the therapeutic process’ and ‘A new journey: towards making a new sense of oneself’. The results of the study highlight the personal and emotional challenge of the formulation process for clients.</jats:p

    The JPL designed MARKIII hypercube supercomputer has been in application service since June 1988 and has had successful application to a broad problem set including electromagnetic scattering, discrete event simulation, plasma transport, matrix algorithms, neural network simulation, image processing, and graphics. Currently, problems that are not homogeneous are being attempted, and, through this involvement with real world applications, the software is evolving to handle the heterogeneous class problems efficiently

    Unobtrusive indicators of culture for organizations: a systematic review

    Get PDF
    We systematically reviewed the literature using unobtrusive measures to study organizational culture. To synthesize, theorize, and evaluate this research, we introduce the concept of an unobtrusive indicator of culture (UIC) for organizations. A UIC measures organizational culture through collecting data without engaging employees, and is conceptualized in terms of cultural artefacts. We identified thirty-five articles, containing 135 distinct UICs, drawn from 16 distinct data sources. UICs coalesced into two groups. First, textual UICs, with culture measured through language patterns in annual reports, employee online reviews, and emails. Second, UICs focusing on organizational practices, for instance, organizational policies or executive rewards. Over two-thirds (68%) of UICs measured values for integrity, results orientation, and clan cultures, and we conjecture that UICs may be most useful for studying aspects of culture sensitive to reporting biases, and benchmarking large samples of organizations. Forty-eight percent of UICs had good or promising construct validity: many were textual UICs, and those focusing on organizational practices were less established. UICs can potentially advance the study of organizational culture, yet must be developed and applied cautiously, with careful consideration of their advantages and limitations, and how they complement existing measurements and conceptualizations of culture

    Mortality and Mindfulness: How Intense Encounters with Death Can Generate Spontaneous Mindfulness

    Get PDF
    Intense encounters with mortality - such as a diagnosis of a terminal illness or a sudden brush with mortality due to an accident or injury - can have positive transformational effects, leading to what positive psychology refers to as ‘flourishing.’ In particular, intense encounters with mortality may generate a heightened sense of appreciation for life, more authentic relationships and lifestyles, and an increased ability to be “mindful”, in the sense of becoming more focused upon the present, and more vividly aware of one’s surroundings. (This is termed ‘externally-oriented mindfulness’.).This can be seen as a form of ‘spontaneous mindfulness’ caused by a re-orienting of attention, away from the future and the past, and into the present. Examples of this shift are given, and other reasons for its emergence are suggested. The positive effects of encountering mortality are contrasted with the findings of Terror Management Theory. The intensity and directness of the individual’s encounter with mortality may be a significant factor in whether it has negative or positive effects. It is suggested that increasing our awareness of mortality - such as by making a conscious effort to contemplate death - can help us to gain some of the positive transformational effects of an intense encounter with mortality (or IEM

    A Fully Nonmetallic Gas Turbine Engine Enabled by Additive Manufacturing of Ceramic Composites

    This publication is the third part of a three part report of the project entitled "A Fully Nonmetallic Gas Turbine Engine Enabled by Additive Manufacturing" funded by NASA Aeronautics Research Institute (NARI). The objective of this project was to conduct additive manufacturing to produce ceramic matrix composite materials and aircraft engine components by the binder jet process. Different SiC powders with median sizes ranging from 9.3 to 53.0 microns were investigated solely and in powder blends in order to maximize powder packing. Various infiltration approaches were investigated to include polycarbosilane (SMP-10), phenolic, and liquid silicon. Single infiltrations of SMP-10 and phenolic only slightly filled in the interior. When the SMP-10 was loaded with sub-micron sized SiC powders, the infiltrant gave a much better result of filling in the interior. Silicon carbide fibers were added to the powder bed to make ceramic matrix composite materials. Microscopy showed that the fibers were well distributed with no preferred orientation on the horizontal plane and fibers in the vertical plane were at angles as much as 45deg. Secondary infiltration steps were necessary to further densify the material. Two to three extra infiltration steps of SMP-10 increased the density by 0.20 to 0.55 g/cc. However, the highest densities achieved were 2.10 to 2.15 g/cc. Mechanical tests consisting of 4 point bend tests were conducted. Samples from the two CMC panels had higher strengths and strains to failure than the samples from the two nonfiber reinforced panels. The highest strengths were from Set N with 65 vol% fiber loading which had an average strength of 66 MPa. Analysis of the fracture surfaces did not reveal pullout of the reinforcing fibers. Blunt fiber failure suggested that there was not composite behavior. The binder jet additive manufacturing method was used to also demonstrate the fabrication of turbine engine vane components of two different designs and sizes. The binder jet method has benefits over the conventional manufacturing of CMCs in that prototype and production parts can be fabricated quickly and economically with no tooling and extensive hand layup

    Divergent trophic responses of sympatric penguin species to historic anthropogenic exploitation and recent climate change

    Get PDF
    The Southern Ocean is in an era of significant change. Historic overharvesting of marine mammals and recent climatic warming have cascading impacts on resource availability and, in turn, ecosystem structure and function. We examined trophic responses of sympatric chinstrap (Pygoscelis antarctica) and gentoo (Pygoscelis papua) penguins to nearly 100 y of shared environmental change in the Antarctic Peninsula region using compound-specific stable isotope analyses of museum specimens. A century ago, gentoo penguins fed almost exclusively on low-trophic level prey, such as krill, during the peak of historic overexploitation of marine mammals, which was hypothesized to have resulted in a krill surplus. In the last 40 y, gentoo penguin trophic position has increased a full level as krill declined in response to recent climate change, increased competition from recovering marine mammal populations, and the development of a commercial krill fishery. A shifting isotopic baseline supporting gentoo penguins suggests a concurrent increase in coastal productivity over this time. In contrast, chinstrap penguins exhibited no change in trophic position, despite variation in krill availability over the past century. The specialized foraging niche of chinstrap penguins likely renders them more sensitive to changes in krill availability, relative to gentoo penguins, as evinced by their declining population trends in the Antarctic Peninsula over the past 40 y. Over the next century, similarly divergent trophic and population responses are likely to occur among Antarctic krill predators if climate change and other anthropogenic impacts continue to favor generalist over specialist species
