An F-type test for detecting departure from monotonicity in a functional linear model

When studying associations between a functional covariate and scalar response using a functional linear model (FLM), scientific knowledge may indicate possible monotonicity of the unknown parameter curve. In this context, we propose an F-type test of monotonicity, based on a full versus reduced nested model structure, where the reduced model with monotonically constrained parameter curve is nested within an unconstrained FLM. For estimation under the unconstrained FLM, we consider two approaches: penalised least-squares and linear mixed model effects estimation. We use a smooth then monotonise approach to estimate the reduced model, within the null space of monotone parameter curves. A bootstrap procedure is used to simulate the null distribution of the test statistic. We present a simulation study of the power of the proposed test, and illustrate the test using data from a head and neck cancer study.     

The changing practice of eating: evidence from UK time diaries, 1975 and 2000

This paper examines some central themes about change in consumption behaviour through an empirical investigation of the practice of eating. It analyses patterns of food consumption in the UK using time diary data from 1975 and 2000. The practice of eating is decomposed into four component activities which are used to explore systematically the inter-relationships between social processes - such as commodification and temporal fragmentation - and ways of providing and consuming food. It charts the expansion of eating out, the degree to which it substitutes for other eating activities, and the implications of its development for social relations and the temporal organization of daily life. Analysis reveals that food consumption continues to be differentiated along established lines of social division, although the content of those divisions has changed and varies across components of the practice. Increasing commodification of the food chain is documented, but without appearing to have a corrosive impact on household organization or social relationships. While tendencies indicative of temporal fragmentation are revealed, counter-tendencies exist which suggest that the practice of eating is resilient to many forms of external pressure. Finally, the application of a practice-based analytical approach permits critical evaluation of theories of social transformation.     

Reconciling care and justice in contesting social harm through performance and arts practice with looked after children and care leavers

The proportion of young people taken into the care of the state has increased recently and there is evidence that this social group suffer negative long‐term outcomes that might be conceptualised by the emergent criminological category of ‘social harm’. Debates in social work around an ethics of care and justice offer different ways of thinking about responding to social harm. This paper reports findings from an innovative arts‐based intervention with Looked After Children and young people and concludes that holding these competing value sets in creative tension is central to the success of the programme in helping young people to cope with and contest social harm.

Family Structure and Children’s Economic Well-Being: Incorporating Same-Sex Cohabiting Mother Families

Research on family structure and child well-being rarely includes children in same-sex parent families, a notable omission since 28 % of female–female couple households contain children. Using the 2010–2013 pooled current population survey (CPS), we examined children’s economic well-being by family structure. These data were ideal for this study because they included a sizeable number of children in same-sex cohabiting mother families and the CPS measured both official and supplemental poverty, incorporating the cohabiting partner. Using the official poverty measure, children in same-sex cohabiting mother families were more likely to be poor than their counterparts in either different-sex cohabiting or married parent families. Using the supplemental poverty measure, children in same-sex mother families were no more likely to be poor than children in all other types of different-sex two-parent families.     

Barriers and Facilitators of Responding to Problem Gambling: Perspectives from Australian Mental Health Services

Despite high rates of comorbidity between problem gambling and mental health disorders, few studies have examined barriers or facilitators to the implementation of screening for problem gambling in mental health services. This exploratory qualitative study identified key themes associated with screening in mental health services. Semi-structured interviews were undertaken with 30 clinicians and managers from 11 mental health services in Victoria, Australia. Major themes and subthemes were identified using qualitative content analysis. Six themes emerged including competing priorities, importance of routine screening, access to appropriate screening tools, resources, patient responsiveness and workforce development. Barriers to screening included a focus on immediate risk as well as gambling being often considered as a longer-term concern. Clinicians perceived problem gambling as a relatively rare condition, but did acknowledge the need for brief screening. Facilitators to screening were changes to system processes, such as identification of an appropriate brief screening instrument, mandating its use as part of routine screening, as well as funded workforce development activities in the identification and management of problem gambling.     

Colorful Disclosures: Identifying Identity-Based Differences and Enhancing Critical Consciousness in Supervision

ABSTRACT

Managing microaggressions and marginalizing experiences while negotiating the ongoing oppression that occurs in micro, mezzo, and macro settings can be particularly challenging for clinicians of color. Thus, supervision with clinicians of color must include affirmation, empowerment, and exploration of the intracultural/intercultural dynamics inherent in the treatment-providing process and clinical supervision. Through case studies, autoethnographic studies of our supervision experiences, and interviews with supervisors and supervisees, we reflect on how axes of identity, including race, power, and privilege, inform practitioners’ clinical lenses and affect their vulnerability in treatment and the clinical supervision dyad. Special attention is placed on the clinical supervisor–clinician–client triad (the triple process) and the interpersonal dynamics of cultural sensitivity, cultural humility, and authentic responsiveness that supervisors aim to model and cultivate in the supervisory relationship. In addition to sustaining clinical growth for clinicians of color, adding this level of complexity to supervision supports equity in direct clinical practice, enhancing efficacy outcomes for clients and communities. Recommendations and pedagogical strategies are offered to support supervisors in initiating difficult dialogues and shifting the paradigm to promote this transformational perspective.     

Adolescents Conceived through Donor Insemination in Mother‐Headed Families: A Qualitative Study of Motivations and Experiences of Contacting and Meeting Same‐donor Offspring

This study interviewed adolescents conceived using sperm donation to examine their experiences of contacting and meeting ‘same‐donor offspring’ (i.e. donor‐conceived offspring raised in different families who share the same donor), their motivations for this contact, and how they make meaning of these relationships. This in‐depth qualitative study involved semi‐structured interviews with 23 young people aged 12–19 years (mean = 14 years). Interviewees were motivated by curiosity about their biological relations and by wanting to extend their family. Contact with same‐donor offspring was described as being either normal/neutral or as a unique experience that was integrated into their identity. This study highlights the importance of contact between same donor offspring, particularly during adolescence, a developmental stage associated with identity formation. The findings have important policy implications as they suggest that donor‐conceived individuals may benefit from contact with others conceived using the same donor prior to the age of 18 years.
