Temporal aspects of child and adolescent time allocation in diverse cultural settings have been difficult to model using conventional statistical techniques. A new statistical approach, Egocentric Relational Event Modelling (EREM), allows for the simultaneous modelling of activity frequency, duration, and sequencing. Here, EREM is applied to a focal follow dataset of Congolese BaYaka forager child and adolescent play and work activities. Results show that, as children age, they engage in less frequent and extended play bouts and more frequent and extended work bouts. Bout frequency and duration were a more sensitive measure for early sex differences than overall time allocation. Sequential patterns of work and play suggest that these activities have short-term energetic trade-offs. This article demonstrates that EREM can reveal stable and variable patterns in child development.

Young people form the primary target demographic of new 'buy now pay later' (BNPL) and digital credit services. Despite consistent data showing young people as a cohort are particularly vulnerable to unsustainable levels of indebtedness, little is known about how young people define and make sense of the experience of being in debt through consumer credit services. This paper explores how indebtedness is experienced and understood in relation to wellbeing through a qualitative study using interviews alongside arts-based participatory methods of bodymapping and sandboxing with 24 young people in the Hunter region of NSW, Australia. These methods enabled particular attention to the embodied and affective elements related to the experience of indebtedness to understand debt's significance for wellbeing for young people. The embodied and affective registers of indebtedness are integral for understanding the conditions informing how wellbeing is negotiated and felt in this context. This study considers the role of BNPL services in young people's economic lives as part of broader processes of financialisation, and the significance of extended and ubiquitous forms of credit for young people's wellbeing.

The Australian disability workforce has grown, and there is compelling evidence that peer work has a number of valuable impacts. Despite these apparent opportunities, there continue to be high levels of unemployment among people with disability and failure to draw on the assets of people with disability in Australian workplaces. To understand these ostensible missed opportunities, this study examined the ways in which lived experience was described as an asset in disability workforce recruitment. Advertisements for positions in New South Wales, Australia, that referred to lived experience or peer work and disability were collected over a 3‐month period. Through a process of content analysis, we found that there were more employment opportunities for people with lived experience of mental illness than for other types of disability. Community engagement was a key function, and peer workers were described as complementary to professionals. Recruitment processes for lived experience jobs were not necessarily accessible. We recommend systemic reforms to facilitate recognition of lived experience as a valuable criterion for disability sector employment and to harness the benefits of a disability peer workforce.

Introduction: Down syndrome (DS) is associated with immune dysregulation and a high risk of early onset Alzheimer's disease (AD). Complement is a key part of innate immunity and driver of pathological inflammation, including neuroinflammation in AD. Complement dysregulation has been reported in DS; however, the pattern of dysregulation and its relationship to AD risk is unclear. Methods: Plasma levels of 14 complement biomarkers were measured in 71 adults with DS and 46 controls to identify DS‐associated dysregulation; impact of apolipoprotein E (APOE) ε4 genotype, single nucleotide polymorphisms (SNPs) in CLU and CR1, and dementia on complement biomarkers was assessed. Results: Plasma levels of complement activation products (TCC, iC3b), proteins (C1q, C3, C9), and regulators (C1 inhibitor, factor H, FHR4, clusterin) were significantly elevated in DS versus controls while FI and sCR1 were significantly lower. In DS with AD (n = 13), C3 and FI were significantly decreased compared to non‐AD DS (n = 58). Neither APOE genotype nor CLU SNPs impacted complement levels, while rs6656401 in CR1 significantly impacted plasma sCR1 levels. Conclusions: Complement is dysregulated in DS, likely reflecting the generalized immune dysregulation state; measurement may help identify inflammatory events in individuals with DS. Complement biomarkers differed in DS with and without AD and may aid diagnosis and/or prediction. Highlights: Complement is significantly dysregulated in plasma of people with DS who show changes in levels of multiple complement proteins compared to controls.People with DS and dementia show evidence of additional complement dysregulation with significantly lower levels of C3 and factor I compared to those without dementia.rs6656401 in CR1 was associated with significantly elevated sCR1 plasma levels in DS.

In this article, we use a collaborative approach to autoethnography to explore experiences of power in relation to our identities as people with disabilities and/or mental illnesses. We draw on elements of Bronfenbrenner's ecological systems framework to consider how we enact our own power or struggle against systemic power in making meaning of our lives. As a team of lived experience researchers we wrote, shared and thematically analysed a series of narratives about our personal (microsystem) and institutional (macrosystem) relationships. Through this research process we were able to identify common experiences of being resilient in the face of institutions that dehumanised and problematised us and tried to render us voiceless—exerting 'power over'. In contrast, reflections on our personal relationships highlighted experiences of reciprocity, respect and autonomy that energised our efforts towards meaningful and powerful identities—'power with'. We conclude that by generating strength through our own advocacy, perseverance and caring relationships, we engage dynamics (mesosystem) of empowerment and identity to resist oppressive power at structural levels. This exemplifies the importance of person-centred social work premised on self-determination, autonomy and dignity, and socially just social work that advocates for equitability and fights structural discrimination.

Complement, a critical defence against pathogens, has been implicated as a driver of pathology in COVID‐19. Complement activation products are detected in plasma and tissues and complement blockade is considered for therapy. To delineate roles of complement in immunopathogenesis, we undertook the largest comprehensive study of complement in COVID‐19 to date, comprehensive profiling of 16 complement biomarkers, including key components, regulators and activation products, in 966 plasma samples from 682 hospitalized COVID‐19 patients collected across the hospitalization period as part of the UK ISARIC4C (International Acute Respiratory and Emerging Infection Consortium) study. Unsupervised clustering of complement biomarkers mapped to disease severity and supervised machine learning identified marker sets in early samples that predicted peak severity. Compared to healthy controls, complement proteins and activation products (Ba, iC3b, terminal complement complex) were significantly altered in COVID‐19 admission samples in all severity groups. Elevated alternative pathway activation markers (Ba and iC3b) and decreased alternative pathway regulator (properdin) in admission samples were associated with more severe disease and risk of death. Levels of most complement biomarkers were reduced in severe disease, consistent with consumption and tissue deposition. Latent class mixed modelling and cumulative incidence analysis identified the trajectory of increase of Ba to be a strong predictor of peak COVID‐19 disease severity and death. The data demonstrate that early‐onset, uncontrolled activation of complement, driven by sustained and progressive amplification through the alternative pathway amplification loop is a ubiquitous feature of COVID‐19, further exacerbated in severe disease. These findings provide novel insights into COVID‐19 immunopathogenesis and inform strategies for therapeutic intervention. [ABSTRACT FROM AUTHOR]
