Effects of parent-child affective quality during high school years on subsequent substance use
The literature indicates that the quality of affective relationships between youth and
parents is associated with lower levels of a range of problem behaviors during childhood,
early and late adolescence. While the protective effect of parental monitoring on
substance use in the high school and post high school years has been demonstrated, there is a knowledge gap concerning effects of parent-child affective quality (PCAQ) during the same periods. We tested a conceptual theoretical model to examine the effects of PCAQ on substance use following high school. The sample was from a RCT that
assessed adolescents in rural Iowa from the seventh grade through two years after high
school (N=456). We specified direct effects of PCAQ in 12th grade on drunkenness,
smoking and illicit drug use during the two years immediately following high school
graduation. We also specified the effects of early substance use initiation (alcohol,
tobacco and marijuana use reported at baseline) on later use. The direct effect of PCAQ
in 12th grade on substance use was significant for all substances during at least one of
the two years past graduation (ypg). Results were: drunkenness 1 ypg, β=-.126, p<.05;
smoking 1 ypg, β=-.119, p<.05; 2 ypg, β=-.146, p<.05; illicit drug use 2 ypg, β=-.165,
p<.05. Some significant indirect effects of PCAQ at baseline, via PCAQ at 12th grade,
were found. Results also indicated significant direct effects of early initiation on two of
the three substances, albeit with a different pattern of effects over time for each
substance by years post high school. Importantly, while early initiation remains the
strongest predictor of long-term tobacco and illicit drug use, results show how PCAQ
might reduce its harmful effects.peer-reviewe
Self-Verification as a Mediator of Mothers’ Self-Fulfilling Effects on Adolescents\u27 Educational Attainment
This research examined whether self-verification acts as a general mediational process of self-fulfilling prophecies. The authors tested this hypothesis by examining whether self-verification processes mediated self-fulfilling prophecy effects within a different context and with a different belief and a different outcome than has been used in prior research. Results of longitudinal data obtained from mothers and their adolescents (N = 332) indicated that mothers’ beliefs about their adolescents’ educational outcomes had a significant indirect effect on adolescents’ academic attainment through adolescents’ educational aspirations. This effect, observed over a 6-year span, provided evidence that mothers’ self-fulfilling effects occurred, in part, because mothers’ false beliefs influenced their adolescents’ own educational aspirations, which adolescents then self-verified through their educational attainment. The theoretical and applied implications of these findings are discussed
Knowledge, Attitudes, and Commitment Concerning Evidence-Based Prevention Programs: Differences Between Family and Consumer Sciences and 4-H Youth Development Educators
We describe the results of a study designed to assess knowledge, perceptions, and attitudes towards evidence-based and other prevention programs among county Extension educators. We examined differences across educators from Family and Consumer Sciences (FCS) and 4-H Youth Development. Analyses based on a multi-state sample of educators revealed significant differences such that, compared to their 4-H counterparts, FCS educators were more knowledgeable of evidence-based programs and had more favorable perceptions and attitudes towards evidence-based and other pre-packaged prevention programs. These findings suggest that Extension administrators should work to encourage the use of evidence-based and other prevention programs, particularly within 4-H
Communication is Key: State-level Organizational Correlates of Readiness for Evidence-based Programming within the Cooperative Extension System
The necessity to implement evidence-based programs to support the healthy development of youth and families is becoming part of national policy. Organizations that are not “ready” to do so will likely lose resources, disallowing them to serve as they have set out to do. Consequently, the current survey study draws from a national sample of Cooperative Extension personnel in 2009 to examine characteristics within their organizational context that facilitate successful change related to youth/family programming. Data were collected from 946 4-H/youth development or Family and Consumer Sciences employees at all levels. Self-reported indices of each state organization’s openness to change, leadership, morale, communication, and resources were constructed to assess the organizational context. Dependent variables included indicators of readiness to implement prevention and evidence-based programming. Results suggest that the organizational context was strongly associated with indicators of readiness for evidence-based prevention programming, and specifically, the clarity of communication was most important
Changes in fluxes of heat, H2O, and CO2 caused by a large wind farm
The Crop Wind-Energy Experiment (CWEX) provides a platform to investigate the effect of wind turbines and large wind farms on surface fluxes of momentum, heat, moisture, and carbon dioxide (CO2). In 2010 and 2011, eddy covariance flux stations were installed between two lines of turbines at the southwest edge of a large Iowa wind farm from late June to early September. We report changes in fluxes of momentum, sensible heat, latent heat, and CO2 above a corn canopy after surface air had passed through a single line of turbines. In 2010, our flux stations were placed within a field with homogeneous land management practices (same tillage, cultivar, chemical treatments). We stratify the data according to wind direction, diurnal condition, and turbine operational status. Within these categories, the downwind–upwind flux differences quantify turbine influences at the crop surface. Flux differences were negligible in both westerly wind conditions and when the turbines were non operational. When the flow is perpendicular (southerly) or slightly oblique (southwesterly) to the row of turbines during the day, fluxes of CO2 and water (H2O) are enhanced by a factor of five in the lee of the turbines (from three to five turbine diameter distances downwind from the tower) as compared to a west wind. However, we observe a smaller CO2 flux increase of 30–40% for these same wind directions when the turbines are off. In the nighttime, there is strong statistical significance that turbine wakes enhance upward CO2 fluxes and entrain sensible heat toward the crop. The direction of the scalar flux perturbation seems closely associated to the differences in canopy friction velocity. Spectra and co-spectra of momentum components and co-spectra of heat also demonstrate nighttime influence of the wind turbine turbulence at the downwind station
Implementation of adolescent family-based substance use prevention programs in health care settings: Comparisons across conditions and programs
The majority of knowledge related to implementation of family-based substance use prevention programs is based on programs delivered in school and community settings. The aim of this study is to examine procedures related to implementation effectiveness and quality of two family-based universal substance use prevention programs delivered in health care settings, the Strengthening Families Program: For Parents and Youth 10–14 (SFP) and Family Matters (FM). These evidence-based programs were delivered as part of a larger random control intervention study designed to assess the influence of program choice vs. assignment on study participation and adolescent substance use outcomes. We also assess the effects of program choice (vs. assignment to program) on program delivery
