Outdoor, Indoor, and Personal Exposure to VOCs in Children

We measured volatile organic compound (VOC) exposures in multiple locations for a diverse population of children who attended two inner-city schools in Minneapolis, Minnesota. Fifteen common VOCs were measured at four locations: outdoors (O), indoors at school (S), indoors at home (H), and in personal samples (P). Concentrations of most VOCs followed the general pattern O ≈ S < P ≤ H across the measured microenvironments. The S and O environments had the smallest and H the largest influence on personal exposure to most compounds. A time-weighted model of P exposure using all measured microenvironments and time–activity data provided little additional explanatory power beyond that provided by using the H measurement alone. Although H and P concentrations of most VOCs measured in this study were similar to or lower than levels measured in recent personal monitoring studies of adults and children in the United States, p-dichlorobenzene was the notable exception to this pattern, with upper-bound exposures more than 100 times greater than those found in other studies of children. Median and upper-bound H and P exposures were well above health benchmarks for several compounds, so outdoor measurements likely underestimate long-term health risks from children’s exposure to these compounds

Upward spirals of positive emotions counter downward spirals of negativity: Insights from the broaden-and-build theory and affective neuroscience on the treatment of emotion dysfunctions and deficits in psychopathology

This review integrates Fredrickson’s broaden-and-build theory of positive emotions with advances in affective neuroscience regarding plasticity in the neural circuitry of emotions to inform the treatment of emotion deficits within psychopathology. We first present a body of research showing that positive emotions broaden cognition and behavioral repertoires, and in so doing, build durable biopsychosocial resources that support coping and flourishing mental health. Next, by explicating the processes through which momentary experiences of emotions may accrue into self-perpetuating emotional systems, the current review proposes an underlying architecture of state-trait interactions that engenders lasting affective dispositions. This theoretical framework is then used to elucidate the cognitive-emotional mechanisms underpinning three disorders of affect regulation, depression, anxiety, and schizophrenia. In turn, two mind training interventions, mindfulness and loving-kindness meditation, are highlighted as means of generating positive emotions that may counter the negative affective processes implicated in these disorders. We conclude with the proposition that positive emotions may exert a countervailing force on the dysphoric, fearful, or anhedonic states characteristic of persons with psychopathology typified by emotional dysfunctions

Craft Publishing: A Proposal for a Programmatic Paradigm Shift in Academic Libraries

This presentation will include the parameters by which an effective, at-cost publishing program may be structured in academic libraries. With advances in technology, electronic storage, and connectivity, and contrary to the claim that such activities may result in a “race to the bottom,” libraries have proven to be natural entities within which to effect a paradigm change in scholarly publishing. Activities to date, however, have been more often than not underfunded and understaffed. Even among those that have been well supported, efforts across the community have been ad hoc. Within the context of recent initiatives and discussions, the authors will outline an emerging model, including staffing, budgeting, and workflow requirements, that is viable and allows for local constraints. The collective output of such operations will serve to mitigate some of the challenges posed by academia’s partnership with the current, established publishing conglomerate. Synopsis Includes information on the University of Nebraska-Lincoln Libraries publishing test case, metrics pertaining to the academic publishing market, and details about what constitutes craft publishing. Conclusion Small-scale publishing in hundreds of libraries in the United States is viable and can serve to balance the economics of the current scholarly publishing market.
