    Empirical 2MASS-WFC3/IR filter transformations from synthetic photometry

    Full text link
    Near-infrared bandpasses on spaceborne observatories diverge from their ground-based counterparts as they are free of atmospheric telluric absorption. Available transformations between respective filter systems in the literature rely on theoretical stellar atmospheres, which are known to have difficulties reproducing observed spectral energy distributions of cool giants. We present new transformations between the 2MASS JHKSJHK_S and HST WFC3/IR F110W, F125W, & F160W photometric systems based on synthetic photometry of empirical stellar spectra from four spectral libraries. This sample comprises over 1000 individual stars, which together span nearly the full HR diagram and sample stellar populations from the solar neighborhood out to the Magellanic Clouds, covering a broad range of ages, metallicities, and other relevant stellar properties. In addition to global color-dependent transformations, we examine band-to-band differences for cool, luminous giant stars in particular, including multiple types of primary distance indicators.Comment: 24 pages, 15 figures, accepted to A

    Introduction: looking beyond the walls

    In its consideration of the remarkable extent and variety of non-university researchers, this book takes a broader view of ‘knowledge’ and ‘research’ than in the many hot debates about today’s knowledge society, ‘learning age’, or organisation of research. It goes beyond the commonly held image of ‘knowledge’ as something produced and owned by the full-time experts to take a look at those engaged in active knowledge building outside the university walls

    Physical and emotional nourishment: Food as the embodied component of loving care of elderly family relatives

    Get PDF
    Purpose This purpose of this study is to examine the fluidity of family life which continues to attract attention. This is increasingly significant for the intergenerational relationship between adult children and their elderly parents. Using practice theory, the aims are to understand the role of food in elderly families and explore how family practices are maintained when elderly transition into care. Design/methodology/approach A phenomenological research approach was used as the authors sought to build an understanding of the social interactions between family and their lifeworld. Findings This study extends theory on the relationship between the elderly parent and their family and explores through practice theory how families performed their love, how altered routines and long standing rituals provided structure to the elderly relatives and how care practices were negotiated as the elderly relatives transitioned from independence to dependence and towards care. A theoretical framework is introduced that provides guidance for the transition stages and the areas for negotiation. Research limitations/implications This research has implications for food manufacturers and marketers, as the demand for healthy food for the elderly is made more widely available, healthy and easy to prepare. The limitations of the research are due to the sample located in East Yorkshire only. Practical implications This research has implications for brand managers of food manufacturers and supermarkets that need to create product lines that target this segment by producing healthy, convenience food. Social implications It is also important for health and social care policy as the authors seek to understand the role of food, family and community and how policy can be devised to provide stability in this transitional and uncertain lifestage. Originality/value This research extends the body of literature on food and the family by focussing on the elderly cared for and their family. The authors show how food can be construed as loving care, and using practice theory, a theoretical framework is developed that can explain the transitions and how the family negotiates the stages from independence to dependence

    Non-conformance with regulatory codes in the non-profit sector: accountability and the discursive coupling of means and ends

    Get PDF
    The concept of means-ends decoupling has recently been suggested as one consequence of the problems organizations face in trying to comply with institutional rules in contexts of institutional complexity. Such decoupling is characterised by the adoption, implementation and scrutiny of particular codes of practice which tend not to deliver the outcomes they were developed to produce. Recent scholarship focusing on this issue has suggested that such decoupling is a consequence of the “trade-off” organizations need to make between compliance and goal achievement most especially when the latter is difficult to evaluate. While recent scholarship has suggested that this tension might be mitigated by the activities of developers of compliance rules, in this paper, we explore how actors internal to an organization, in this case, two charitable organizations mitigate this tension via non-conformance with particular codes. We focus on how the process of accounting for non-conformance results in the discursive coupling of means and ends as actors creatively develop vocabularies of motive which respond to anticipated social criticism
