    Abstract The first search for nonresonant $B_c^+\to\pi^+\mu^+\mu^-$ decays is reported. The analysis uses proton-proton collision data collected with the LHCb detector between 2011 and 2018, corresponding to an integrated luminosity of 9 fb$^{-1}$. No evidence for an excess of signal events over background is observed and an upper limit is set on the branching fraction ratio ${\cal B}(B_c^+\to\pi^+\mu^+\mu^-)/{\cal B}(B_c^+\to J/\psi \pi^+) < 2.1\times 10^{-4}$ at $90\%$ confidence level. Additionally, an updated measurement of the ratio of the $B_c^+\to\psi(2S)\pi^+$ and $B_c^+\to J/\psi \pi^+$ branching fractions is reported. The ratio ${\cal B}(B_c^+\to\psi(2S)\pi^+)/{\cal B}(B_c^+\to J/\psi \pi^+)$ is measured to be $0.254\pm 0.018 \pm 0.003 \pm 0.005$, where the first uncertainty is statistical, the second systematic, and the third is due to the uncertainties on the branching fractions of the leptonic $J/\psi$ and $\psi(2S)$ decays. This measurement is the most precise to date and is consistent with previous LHCb results.

    Abstract Background and objectives: There has been increased attention in recent years on self-employment in later life, with about 1 in 5 workers past of the age of 50 working for themselves. This study aims to build upon previous documentation of the characteristics of self-employed older adults by estimating how these characteristics vary by age.
    Research design and methods: Using 7 waves of the Health and Retirement Study with a sample of more than 16,000 working older adults, this study considers how the association between self-employment and sociodemographic characteristics; indicators of human, social, and financial capital; and risk tolerance differ between adults aged 50-61 and 62 years and older. Binary logistic regression and seemingly unrelated estimation are used to estimate and compare the characteristics by age group.
    Results: Compared to wage-and-salary work and controlling for all other factors in the models, the oldest self-employed group was more likely to identify as Black, report lower health, and receive health insurance from several sources than the younger group. Further, the older group reported lower individual earnings from work yet higher total household income (less individual earnings) and was also less likely to formally volunteer at the highest commitment levels.
    Discussion and implications: With some exceptions, these results indicate that the diversity of self-employed older adults within traditional retirement age is greater than among those before this age. Implications regarding how access to key safety net programs, such as Social Security retirement benefits and Medicare, may lead to this finding are discussed.

    Abstract Background: Peer-support specialists-individuals with diagnosed mental illnesses who provide support services to other adults with diagnosed mental health issues-often feel stigmatized and undervalued at work, leading to negative personal- and job-related outcomes. Given their important link to positive service user outcomes, this study assessed how peer-support specialists perceive fairness and feel valued in the workplace.
    Methods: Peer-support specialists (
    Findings: Ranging in age from 20 to 77 years and identifying predominantly as White (81.0%) and female (62.9%), respondents noted that fair practices in the workplace would increase their job satisfaction, with no significant differences observed by gender or race. Most peer-support specialists felt valued by the people they serve (97.1%) and fellow peer-support specialists (92.7%). However, fewer reported feeling valued by administrators (64.6%) and clinicians (60.6%).
    Conclusions/application to practice: Peer-support specialists value fairness at the workplace and feel undervalued by some staff. This study highlights peer-support specialists' important role in behavioral health services and suggests that healthcare professionals, including occupational health specialists, are important stakeholders in creating fairer workplaces and increasing peer-support specialists' sense of being valued, leading to improved personal and organizational outcomes.

    Abstract Introduction: Formal volunteering in later life is beneficial for both physical and psychological well-being. However, research points to potential selection bias because older adults with key advantages, such as wealth, are more likely to volunteer and reap its benefits. Accordingly, this study addresses this selection bias by considering the characteristics of volunteers and nonvolunteers using the inverse probability of treatment weighting. It also examines whether volunteering has differential impacts between the highest and lowest wealth quintiles using inverse probability of treatment weighting.
    Methods: Data were analyzed from the 2004-2016 waves of the Health and Retirement Study (N=90,881). The weights, created using a machine learning method, were incorporated in the analysis to estimate the treatment effects along with relevant covariates. Analyses were conducted in 2020.
    Results: Volunteering enhanced self-reported health and reduced depressive symptoms in the full sample. Furthermore, those in the lowest wealth quintile experienced significantly better self-reported health from volunteering than their wealthy counterparts. Volunteering was associated with fewer depressive symptoms regardless of wealth status.
    Conclusions: The study enhances the understanding of formal volunteering and health while suggesting that volunteers with low wealth may benefit more from volunteering in terms of their health. Hindrances to volunteering among the least wealthy, such as financial distress, discrimination, or lack of organizational support, may attenuate the benefits of voluntary activity.

    Abstract While the continent of Africa currently has the lowest share of adults aged 60 and older in its population among all world regions, the total number of older Africans is projected to triple between 2020 and 2050. Nigeria-Africa's leading economy and most populated country-has the highest number of older people in the continent and the 19th highest across the globe, with the population of Nigerians aged 65 and older projected to nearly triple by 2050. However, the increase in older Nigerians is occurring against the backdrop of extreme poverty, unsolved development problems, socioeconomic inequality, the HIV/AIDS epidemic, and a decline in the traditional care and support of older adults. Additionally, the absence of an operational national aging policy or safety net services and programs poses a unique challenge to older Nigerians and their families. In this article, we examined social statistics and the current literature to describe aging in the Nigerian context. Our findings highlight the importance of establishing effective governmental policy interventions for the adequate care and support of older Nigerians and the training of gerontological professionals. This article will describe the demography of aging in Nigeria, significant areas of research, key scholars and publicly available data sets, public policy issues, and emerging issues affecting the health and well-being of older Nigerians.

    Abstract The Senior Community Service Employment Program (SCSEP) is a U.S.-based job-training program that serves unemployed workers aged 55 and older with incomes at or below 125% of the federal poverty level. While federal funds are set aside to serve Asian workers in SCSEP, little is known about their characteristics and experiences. In response, this pilot study aimed to document the health, well-being, and experiences of older Asian SCSEP participants in Massachusetts through the completion of a survey. Respondents (

    Abstract It has long been the goal of many gerontological social work scholars to increase the ability and opportunity for people to be engaged in paid and unpaid work throughout the life course. Yet the COVID-19 pandemic is revealing and exacerbating the financial insecurity of many older adults. In this paper, we review information related to older workers and how they might be affected by this pandemic and its aftermath, paying particular attention to the most socioeconomically and physically vulnerable older workers. We also offer first-hand experiences from our careers working with and conducting scholarship on older workers, paying particular attention to recent actions by many in the Senior Community Service Employment Program (SCSEP) network to provide paid sick leave to its low-income, older adult participants. We conclude with implications for social work scholarship and teaching, noting the uptick in technology use among older adults and the disparities that remain, as well as teaching that integrates discussions on the lifelong and cumulative effects of inequalities and marginalization and the need for additional researcher, student, and community collaborations.

    Abstract Introduction: This study examines how receiving a dementia diagnosis influences social relationships by race and ethnicity.
    Methods: Using data from the Health and Retirement Study (10 waves; 7,159 observations) of adults 70 years and older predicted to have dementia using Gianattasio-Power scores (91% accuracy), this study assessed changes in social support, engagement, and networks after a dementia diagnosis. We utilized quasi-experimental methods to estimate treatment effects and subgroup analyses by race/ethnicity.
    Results: A diagnostic label significantly increased the likelihood of gaining social support but reduced social engagement and one measure of social networks. With some exceptions, the results were similar by race and ethnicity.
    Discussion: Results suggest that among older adults with assumed dementia, being diagnosed by a doctor may influence social relationships in both support-seeking and socially withdrawn ways. This suggests that discussing services and supports at the time of diagnosis is important for healthcare professionals.

    Abstract The federal Senior Community Service Employment Program (SCSEP) provides on-the-job training to people 55 years and older with incomes at or below 125% of the federal poverty level with multiple barriers to employment. This study examined the processes by which SCSEP may influence participant financial, physical, and mental well-being. We engaged 15 SCSEP participants and case managers over four virtual and one telephone session using a participatory research method called community-based system dynamics. Activities included identifying key problem trends, variable elicitation, developing a causal map, and identifying changes to the system to increase participant well-being. Respondents identified how individual, organizational, and program and policy factors relate to participant well-being (e.g., SCSEP participation reduces social isolation, which increases desire to participate) and suggested program and policy recommendations to strengthen SCSEP (e.g., benchmarks of success should include health and well-being outcomes). These findings highlight the benefits and potential of this long-running program.

    Abstract While older entrepreneurs are more likely to be male, white, and have higher levels of human, social, and financial capital, we know less about interest in later-life entrepreneurship. This study estimates entrepreneurial interest in a nationally representative sample of Americans aged 50 to 70 using partial proportional odds modeling. We estimate that more than 31 million older Americans have some interest in entrepreneurship and reveal key predictors of this interest (e.g., younger age). Importantly, the findings indicate that a more diverse group of older adults are interested in entrepreneurship than have become entrepreneurs, suggesting the need for additional research on the potential disparities between entrepreneurial interest and action in later life.
