To analyze long-term consequences of homelessness, the authors compared 388 formerly homeless children 55 months after shelter entry with 382 housed peers, birth to 17, using mother- and child-reported health, mental health, community involvement, cognitive performance, and educational records. Both groups scored below cognitive and achievement norms. Small group differences favored housed 4- to 6-year-olds on cognition and 4- to 10-year-olds on mental health only. Child care and recent stressful events, which were high, were as or more important than prior homelessness. Only children living with mothers were included, potentially biasing results. Policy implications are discussed.

This paper argues for the need to advance promotion efforts and proposes a conceptual framework for promotion of social change. A brief review is presented of traditional frameworks for the prevention of mental and social disorders and the promotion of wellness and social competencies, with attention to the ways in which promotion of social change extends and departs from these frameworks. In a framework for promoting social change, we advocate for promoting dynamic processes within systems, rather than outcomes within individuals. Systems are viewed as flexible and capable of facilitating multiple adaptive pathways for individuals and groups. Promoting social change also involves careful attention to critical analysis, values, language, and contextual processes. Examples are discussed throughout to illustrate how these principles have been used in the past and can be implemented in future efforts to promote social change.

Citizen science is an important way of engaging a broad range of audiences in science inquiry by participating in research that asks novel questions and unearths new knowledge and new questioning. Though citizen science projects are quite diverse in their scientific pursuits, all projects share the common element of involving volunteers directly in some aspect of science inquiry. Thus, it is essential for citizen science projects to determine their participants' capacity to learn and successfully perform science inquiry skills, such as making scientific observations, collecting and analyzing data, and sharing findings. Such skill gains are essential to (a) ensure high quality data that can be used in meaningful scientific research, and (b) achieve broader goals such as developing a participant's identity as a contributor to science. However, we do not yet fully understand how improvement in participants' inquiry skills through citizen science advances our knowledge of public engagement with science. In this essay, we offer embedded assessment as an effective method to capture participant skill gains, and encourage citizen science leaders, evaluators, and researchers to develop authentic methods that address the complexities of measuring skill development within the context of citizen science.
