Participatory research meets validated outcome measures: Tensions in the co‐production of social care evaluation

Funding for care service research is increasingly subject to the satisfaction of two requirements: public involvement and adoption of validated outcome tools. This study identifies competing paradigms within these requirements and reveals significant challenges faced by researchers who seek to satisfy them. The focus here is on a study co‐produced between academic researchers and people with experience of adult social care services. It examines to what extent research studies can conduct high‐quality public involvement and genuine co‐production of knowledge, whilst attempting to produce quantifiable outcome scores. Findings add to debate around how to incorporate diverse perspectives in research, which may draw on incommensurate accounts of validity and reliability. Findings also highlight constructive attempts by academic and co‐researchers to make the combination of approaches work in the field. These small scale acts of researcher agency indicate some scope to combine the two approaches in future research studies. However, conclusions foreground the importance of broader awareness of how tensions and power imbalances related to this combination of approaches play out in social policy research practice.     

Challenges to Aging in Place: Understanding Home Maintenance Difficulties

Age-related declines in capabilities may compromise older adults' ability to maintain their homes thus threatening successful aging in place. Structured interviews were conducted with forty-four independently living older adults (M(age) = 76.1, SD = 4.7) to discuss difficult home maintenance tasks and how they managed those tasks. Solutions to managing difficulties were categorized as person-related or environment-related. The majority (85%) of responses were person-related solutions. An understanding of the specific challenges that older adults face in maintaining their homes can guide redesign efforts and interventions to effectively support older adults' desire to age in place.     

The effect of respondent's kinship position on reported levels of integrational contact: USA and Japan

Intergenerational relationships are a topic of general concern to social scientists because of the importance of the family for individual's well-being, especially in times of crisis. Hence, a considerable amount of research on relationships between parents and their adult children has been published in a broad array of social science journals. Most of this research examines intergenerational relationships from the perspective of only one generation and implicitly assumes that we would get the same results if we were to examine the relationships from the point of view of other family members. In societies where there are strong norms regarding kin contact, this assumption is likely to be invalid. This research examines reported levels of face-to-face contact among kin in the USA and Japan, and tests whether these reports are systematically different for respondents in some kinship positions than in others. The results show that norms favoring patrilineal contact in Japan can produce reporting bias. In Japan, married daughters tend to underreport levels of contact with their parents. In the USA, children-in-law report lower levels of visiting.     

A note on the moments of stochastic shrinkage parameters in ridge regression

The purpose of this note is to gain insight on the performance of two well known operational Ridge Regression estimators by deriving the moments of their stochastic shrinkage parameters. We also show that, under certain conditions, one of them has bounded moments.     

Percentiles of sums of heavy-tailed random variables: beyond the single-loss approximation

A perturbative approach is used to derive approximations of arbitrary order to estimate high percentiles of sums of positive independent random variables that exhibit heavy tails. Closed-form expressions for the successive approximations are obtained both when the number of terms in the sum is deterministic and when it is random. The zeroth order approximation is the percentile of the maximum term in the sum. Higher orders in the perturbative series involve the right-truncated moments of the individual random variables that appear in the sum. These censored moments are always finite. As a result, and in contrast to previous approximations proposed in the literature, the perturbative series has the same form regardless of whether these random variables have a finite mean or not. For high percentiles, and specially for heavier tails, the quality of the estimate improves as more terms are included in the series, up to a certain order. Beyond that order the convergence of the series deteriorates. Nevertheless, the approximations obtained by truncating the perturbative series at intermediate orders are remarkably accurate for a variety of distributions in a wide range of parameters.
