  • Older adults who age at home independently are often celebrated as having anticipated and planned for their care needs in the later stages of life, whereas those who receive assistance from home support services are often stigmatised as dependent and characterised as a ‘drain on the system’. However, this thematic analysis of interview data from 12 home care clients in two Canadian provinces offers evidence that counters the assumption that home care clients are passive recipients of care. Extending Corbin and Strauss' theorisation of how individuals manage chronic conditions alongside Dorothy Smiths' conception of work, we explore how home care clients ‘work’ to receive care as they age in place. Specifically, home care clients not only engage in daily life work, illness work and biographical work, but also advocate for themselves and their workers, co-ordinate and negotiate with members of their caring convoys and networks, and adapt in various ways to navigate personal, relational, structural and policy-level challenges. We suggest that work done by older adults who are ageing in place be addressed, acknowledged and incorporated into care planning and operational policy development to challenge both the stigma of dependency and neoliberal narratives of self-sufficiency.

  • Objective:

    To evaluate the validity and reproducibility of a 152-item semi-quantitative FFQ (SFFQ) for estimating flavonoid intakes.

    Design:

    Over a 1-year period, participants completed two SFFQ and two weighed 7-d dietary records (7DDR). Flavonoid intakes from the SFFQ were estimated separately using Harvard (SFFQHarvard) and Phenol-Explorer (SFFQPE) food composition databases. 7DDR flavonoid intakes were derived using the Phenol-Explorer database (7DDRPE). Validity was assessed using Spearman’s rank correlation coefficients deattenuated for random measurement error (r s ), and reproducibility was assessed using rank intraclass correlation coefficients.

    Setting:

    This validation study included primarily participants from two large observational cohort studies.

    Participants:

    Six hundred forty-one men and 724 women.

    Results:

    When compared with two 7DDRPE, the validity of total flavonoid intake assessed by SFFQPE was high for both men and women (r s = 0·77 and r s = 0·74, respectively). The r s for flavonoid subclasses ranged from 0·47 for flavones to 0·78 for anthocyanins in men and from 0·46 for flavonols to 0·77 for anthocyanins in women. We observed similarly moderate (0·4–0·7) to high (≥0·7) validity when using SFFQHarvard estimates, except for flavonesHarvard (r s = 0·25 for men and r s = 0·19 for women). The SFFQ demonstrated high reproducibility for total flavonoid and flavonoid subclass intake estimates when using either food composition database. The intraclass correlation coefficients ranged from 0·69 (flavonolsPE) to 0·80 (proanthocyanidinsPE) in men and from 0·67 (flavonolsPE) to 0·77 (flavan-3-ol monomersHarvard) in women.

    Conclusions:

    SFFQ-derived intakes of total flavonoids and flavonoid subclasses (except for flavones) are valid and reproducible for both men and women.

  • Satellite altimetric time series allow high-precision monitoring of ice-sheet mass balance. Understanding elevation changes in these regions is important because outlet glaciers along ice-sheet margins are critical in controlling flow of inland ice. Here we discuss a new airborne altimetry dataset collected as part of the ICECAP (International Collaborative Exploration of the Cryosphere by Airborne Profiling) project over East Antarctica. Using the ALAMO (Airborne Laser Altimeter with Mapping Optics) system of a scanning photon-counting lidar combined with a laser altimeter, we extend the 2003–09 surface elevation record of NASA’s ICESat satellite, by determining cross-track slope and thus independently correcting for ICESat’s cross-track pointing errors. In areas of high slope, cross-track errors result in measured elevation change that combines surface slope and the actual Δz/Δt signal. Slope corrections are particularly important in coastal ice streams, which often exhibit both rapidly changing elevations and high surface slopes. As a test case (assuming that surface slopes do not change significantly) we observe a lack of ice dynamic change at Cook Ice Shelf, while significant thinning occurred at Totten and Denman Glaciers during 2003–09.

  • Background

    Both subjective and objective information is necessary to assess quality of life (QOL).

    Aims

    To explore the role of subjective and objective QOL dimensions and their cross-sectional and longitudinal predictors.

    Method

    The relationship between QOL, as measured by the Lancashire Quality of Life Profile (LQL), and demographic variables, diagnosis, psychopathology, disability, functioning, affect balance, self-esteem, service use and service satisfaction was investigated at two points in time, using factor analysis and multiple regression techniques.

    Results

    One subjective and two objective LQL factors with strong face validity were identified. Cross-sectional predictors of the subjective factor were primarily subjective measures; longitudinally, few predictors of this factor were identified. The cross-sectional and longitudinal predictors of the objective factors were primarily demographic and observer-rated measures.

    Conclusions

    Subjective and objective data are distinct types of information. Objective measures may be more suitable in detecting treatment effects. Subjective information is necessary to complete the QOL picture and to enhance the interpretation of objective data.
