    Editorial: Helping Scientists to Communicate Well for all Considered: Strategic Science Communication in an Age of Environmental and Health Crises

    Get PDF
    From documenting evidence-based science communication training programs to examining issues of intersectionality and inclusivity in science communication, each of the 12 articles in this special issue offers a unique perspective on science communication, public engagement, and inclusivity. The case studies of training programs provide helpful lessons learned that have broad applicability. The descriptions of how social scientific and rhetorical approaches have been used to enhance inclusive science communication offer new insights into more effective science communication practices. Our hope is that, taken together, these articles will inspire improvements in our collective ability to more effectively and equitably apply scientific research to meet societal needs

    Creating a Foundation for the Causal Relationship Between Libraries and Learning: A Proposed Application of Nursing and Public Health Research Methods

    Thomas Cook, a renowned causal research expert and professor of sociology, psychology, education, and social policy at Northwestern University (USA), called for school library researchers to parallel causality determination efforts in health-related fields. In this paper, we respond to Dr. Cook’s challenge with a proposed research design centered on Mixed Research Synthesis (MRS) as part of process validated by the U.S. Department of Education and National Science Foundation’s Common Guidelines for Education Research and Development. MRS studies, often used in nursing and public health research to develop causal theories, enable researchers to develop evidence summaries; identify and adjudicate rival and companion theories, and determine the active ingredients and weak links in the implementation chain of interventions, programs, and policies. MRS is the essential first step in a possible ongoing multi-phased research agenda designed to progress from theory building to theory testing to causal determination. In addition to building on and extending school librarianship’s heritage in replicated correlational research and strong affective value, the researchers’ proposed MRS implementation will test the usefulness of a technique that has never been used in school settings and will provide a useful entry point for researchers concerned with other types of libraries

    Race and Ethnicity, Obesity, Metabolic Health, and Risk of Cardiovascular Disease in Postmenopausal Women

    Background It is unclear whether obesity unaccompanied by metabolic abnormalities is associated with increased cardiovascular disease risk across racial and ethnic subgroups. Methods and Results We identified 14 364 postmenopausal women from the Women\u27s Health Initiative who had data on fasting serum lipids and serum glucose and no history of cardiovascular disease or diabetes at baseline. We categorized women by body mass index (in kg/m2) as normal weight (body mass index 18.5 to P=0.05). Obese black women without metabolic syndrome had higher adjusted risk (HR 1.95) than obese white women (HR 1.07; interaction P=0.02). Among women with only 2 metabolic abnormalities, cardiovascular risk was increased in black women who were overweight (HR 1.77) or obese (HR 2.17) but not in white women who were overweight (HR 0.98) or obese (HR 1.06). Overweight and obese women with ≤1 metabolic abnormality did not have increased cardiovascular risk, regardless of race or ethnicity. Conclusions Metabolic abnormalities appeared to convey more cardiovascular risk among black women

    ObjectivesThe aim of this study was to examine the independent and joint associations of sitting time and physical activity with risk of incident cardiovascular disease (CVD).BackgroundSedentary behavior is recognized as a distinct construct beyond lack of leisure-time physical activity, but limited data exist on the interrelationship between these 2 components of energy balance.MethodsParticipants in the prospective Women’s Health Initiative Observational Study (n = 71,018), 50 to 79 years of age and free of CVD at baseline (1993 to 1998), provided information on sedentary behavior, defined as hours of sitting/day, and usual physical activity at baseline and during follow-up through September 2010. First CVD (coronary heart disease or stroke) events were centrally adjudicated.ResultsSitting ≥10 h/day compared with ≤5 h/day was associated with increased CVD risk (hazard ratio: 1.18, 95% confidence interval: 1.09 to 1.29) in multivariable models including physical activity. Low physical activity was also associated with higher CVD risk (p for trend < 0.001). When women were cross-classified by sitting time and physical activity (p for interaction = 0.94), CVD risk was highest in inactive women (≤1.7 metabolic equivalent task-h/week) who also reported ≥10 h/day of sitting. Results were similar for coronary heart disease and stroke when examined separately. Associations between prolonged sitting and risk of CVD were stronger in overweight versus normal weight women and women 70 years of age and older compared with younger women.ConclusionsProlonged sitting time was associated with increased CVD risk, independent of leisure-time physical activity, in postmenopausal women without a history of CVD. A combination of low physical activity and prolonged sitting augments CVD risk
