A Mutualism, Affiliation and Status Seeking (MASS) Framework of Fundamental Affective Dynamics and their Survival Benefits

Primates have developed a unique set of complex drives for successful group living, yet theorists rarely contemplate their taxonomy and how such drives relate to affective dynamics fundamental for group success. Affective dynamics and drive fulfillment exert mutual influence on one another, ultimately collectively promoting or undermining survival. We first identify six core benefits of group living common among both humans and other animals, and from this foundation we propose three broad social drives that have evolved to preserve or enhance group living benefits: (i) Mutualism comprises cooperation, reciprocity, trust, and fairness; (ii) Affiliation comprises assimilation and belonging, whereby one aims to fit into the group through adherence to group norms and ideologies; (iii) Status-Seeking is represented by a drive to build one’s value in the group and acquire differential access to mates and other resources. We identify affective dynamics that facilitate each social drive: (i) Reactive flexibility involves qualitative shifts in affect in response to shifting goals, which facilitates mutualism; (ii) Affective synchrony is the reproduction of another individual’s emotions in oneself and facilitates social affiliation; (iii) Regulatory flexibility facilitates status-seeking through a broad repertoire of regulatory approaches during strategic behavioral pursuits. Finally, we posit that fulfilling Mutualism, Affiliation, and Status-Seeking (MASS) drives enhances the benefits of social living and supports development of fundamental affective dynamics.

Vision impairment and differential access to eye health services in Aotearoa New Zealand: protocol for a scoping review

IntroductionIn Aotearoa New Zealand, Māori and Pacific people experience worse health outcomes compared with other New Zealanders. No population-based eye health survey has been conducted, and eye health services do not generate routine monitoring reports, so the extent of eye health inequality is unknown. This information is required to plan equitable eye health services. Here we outline the protocol for a scoping review to report the nature and extent of the evidence reporting vision impairment, and the use of eye health services by ethnicity in New Zealand.Methods and analysisAn information specialist will conduct searches on MEDLINE and Embase, with no limit on publication dates or language. We will search the grey literature via websites of relevant government and service provider agencies. Reference lists of included articles will be screened. Observational studies will be included if they report the prevalence of vision impairment, or any of the main causes (cataract, uncorrected refractive error, macular degeneration, glaucoma or diabetic retinopathy) or report the use of eye health services in New Zealand among people of any age. Two authors will independently review titles, abstracts and full-text articles, and complete data extraction. Overall findings will be summarised using descriptive statistics and thematic analysis, with an emphasis on disaggregation by ethnicity where this information is available.Ethics and disseminationEthical approval has not been sought as our review will only include published and publicly accessible data. We will publish the review in an open access peer-reviewed journal. We anticipate the findings will be useful to organisations and providers in New Zealand responsible to plan and deliver eye care services, as well as stakeholders in other countries with differential access to eye care.Registration detailsThe protocol has been registered with Open Science Framework (https://osf.io/yw7xb).

Addressing and Inspiring Vaccine Confidence in Black, Indigenous, and People of Color (BIPOC) during the COVID-19 Pandemic

During the COVID-19 pandemic, we have witnessed profound health inequities suffered by Black, Indigenous, and People of Color (BIPOC). These manifested as differential access to testing early in the pandemic, rates of severe disease and death 2-3 times higher than White Americans, and now, significantly lower vaccine uptake compared with their share of the population affected by COVID-19. This article explores the impact of these COVID-19 inequities (and the underlying cause, structural racism) on vaccine acceptance in BIPOC populations, ways to establish trustworthiness of healthcare institutions, increase vaccine access for BIPOC communities, and inspire confidence in COVID-19 vaccines.

Thirty-five years later: Long-term effects of the Matlab maternal and child health/family planning program on older women’s well-being

Family planning programs are believed to have substantial long-term benefits for women’s health and well-being, yet few studies have established either extent or direction of long-term effects. The Matlab, Bangladesh, maternal and child health/family planning (MCH/FP) program afforded a 12-y period of well-documented differential access to services. We evaluate its impacts on women’s lifetime fertility, adult health, and economic outcomes 35 y after program initiation. We followed 1,820 women who were of reproductive age during the differential access period (born 1938–1973) from 1978 to 2012 using prospectively collected data from the Matlab Health and Demographic Surveillance System and the 1996 and 2012 Matlab Health and Socioeconomic Surveys. We estimated intent-to-treat single-difference models comparing treatment and comparison area women. MCH/FP significantly increased contraceptive use, reduced completed fertility, lengthened birth intervals, and reduced age at last birth, but had no significant positive impacts on health or economic outcomes. Treatment area women had modestly poorer overall health (+0.07 SD) and respiratory health (+0.12 SD), and those born 1950–1961 had significantly higher body mass index (BMI) in 1996 (0.76 kg/m2) and 2012 (0.57 kg/m2); fewer were underweight in 1996, but more were overweight or obese in 2012. Overall, there was a +2.5 kg/m2 secular increase in BMI. We found substantial changes in lifetime contraceptive and fertility behavior but no long-term health or economic benefits of the program. We observed modest negative health impacts that likely result from an accelerated nutritional transition among treated women, a transition that would, in an earlier context, have been beneficial.

The Nature of Privilege: Intergenerational Wealth in Animal Societies

Rampant structural inequality exists across human societies, exerting a powerful influence on the health of individuals around the globe. Differential access to – and variation in – material wealth contributes greatly to this imbalance. Intergenerational transfer of material wealth can advantage some individuals over less fortunate individuals, shaping divergent destinies and creating a hierarchy of privilege. This concept is familiar within the context of human economic and social systems, but we argue that privilege is not a uniquely human phenomenon. Rather, privilege has evolved multiple times and its phylogenetic reach may be startlingly widespread across the Tree of Life, raising the provocative possibility that comparative study of privilege may offer insights leading to effective strategies countering inequality in human societies.
