Prevalence, age of decision, and interpersonal warmth judgements of childfree adults: Replication and extensions.

Childfree individuals, who are also described as 'childless by choice' or 'voluntarily childless', have decided they do not want biological or adopted children. This is an important population to understand because its members have unique reproductive health and end-of-life needs, and they encounter challenges managing work-life balance and with stereotypes. Prior estimates of childfree adults' prevalence in the United States, their age of decision, and interpersonal warmth judgements have varied widely over time and by study design. To clarify these characteristics of the contemporary childfree population, we conduct a pre-registered direct replication of a recent population-representative study. All estimates concerning childfree adults replicate, boosting confidence in earlier conclusions that childfree people are numerous and decide early in life, and that parents exhibit strong in-group favoritism while childfree adults do not.

Prevalence and characteristics of childfree adults in Michigan (USA).

Childfree individuals choose not to have children, which makes them a distinctive group from parents who have had children, not-yet-parents who plan to have children, and childless indivduals who would have liked to have children. Most research on parental status and psychosocial characteristics has not effectively distinguished childfree individuals from other non-parents or has relied on non-representative samples. In this study, we use a representative sample of 981 Michigan adults to estimate the prevalence of childfree individuals, to examine how childfree individuals differ from parents and other types of non-parents in life satisfaction, political ideology, and personality, and to examine whether childfree individuals are viewed as an outgroup. We find that over a quarter of Michigan adults identified as childfree. After controlling for demographic characteristics, we find no differences in life satisfaction and limited differences in personality traits between childfree individuals and parents, not-yet-parents, or childless individuals. However, childfree individuals were more liberal than parents, and those who have or want(ed) children felt substantially less warm toward childfree individuals than childfree individuals felt toward each other. Given the prevalence of childfree individuals, the risks of their outgroup status, and their potential role in politics as a uniquely liberal group, it is important for demographic research to distinguish the childfree from others and to better understand these individuals.

Using Social Network Analysis to Identify Successful Relationship Patterns Within Sexual Assault Response Teams (SARTs).

The current study used social network analysis (SNA) to examine relationships within three effective Sexual Assault Response Teams (SARTs) that coordinate the response of legal, medical, and advocacy organizations to sexual assault. Within each SART, organizations reported on each other member organization valuing their role, serving as a resource to their work, and communication outside of official meetings. Across the SARTs, there was high connectedness and reciprocity and low to moderate dependence on one organization to drive relationships. However, there was dependence on a subgroup of organizations to drive additional communication relationships. Implications for managing relationships in SARTs are discussed.

Making or buying evidence: Using transaction cost economics to understand decision-making in public school districts.

We propose transaction cost economics theory as a tool for exploring when school administrators rely on information from two types of sources: internal sources like their own colleagues, and external sources like researchers and government agencies. The theory's application is illustrated in a comparative case study of two public school districts in Michigan. Consistent with the theory's predictions, the smaller, homogeneous, high-performing district used more external sources of information, while the larger, diverse, low-performing district used internal sources of information. We conclude by identifying some strengths and limitations of the theory, which can serve as starting points for debate.
