Effects of Context and Feelings on Perceptions of Genetically Modified Food

Recently, there has been a surge of interest in the role of feelings in framing perceptions and decisions about risk, yet no study has specifically examined the impact of feelings on perceptions/judgments about biotechnology. This exploratory study investigated current perceptions of genetically modified (GM) food to examine (1) the effects of context (making judgments about GM food at the same time as rating other current areas of concern), and (2) the effect of feelings of dread (integral affect) and background feelings of stress (negative incidental affect) on risk judgments about GM food. An established psychometric method (semantic differential task) used with a sample of 126 adults (recruited "topic-blind," mostly from a student population) showed that, when rated in the context of other current concerns such as human cloning and Creutzfeldt-Jakob disease (CJD), there was less concern about GM food than might have been anticipated. Participants were recruited "topic-blind" in order to ensure that they were unaware that the focus of the research was on GM food specifically (and thus preventing biased recruitment to the study). Relative to 19 other current concerns GM food was "not dreaded," not viewed as "unethical," was judged as "controllable," and was seen as the least "risky" of all the issues studied. GM food was viewed as a "hot topic," a new risk, and as relatively unnatural (although it was not the highest rated concern on this scale). Ratings of risks across concerns by individuals experiencing high levels of negative incidental affect (stress) did not differ significantly from those reporting low stress.     

Increasing compliance with stretch breaks in computer users through reminder software

In order for a repetitive strain injury (RSI) prevention program to be effective, it is important to implement strategies to maintain a client's compliance with the program. This quantitative study explored the effectiveness of computer reminder software in increasing compliance with a stretching program designed to prevent RSI associated with prolonged computer use. Data were collected from a convenience sample of 26 participants who were instructed in a preventative stretching program and assigned to either a treatment group with the computer reminder software, or a control group without the software. To measure compliance, all participants recorded the number of times per day they stretched. Although a statistically significant difference was not found in the mean number of stretch breaks taken by the two groups (p = 0.09), further analysis suggested a type II error may have occurred. The effect size, d, revealed a large effect suggesting that the computer software had an impact on the frequency of stretch breaks, with the mean number of breaks per hour of work greater for the treatment group. Results strongly suggest that further research is warranted in this area.     

Missing data techniques for multilevel data: implications of model misspecification

When modeling multilevel data, it is important to accurately represent the interdependence of observations within clusters. Ignoring data clustering may result in parameter misestimation. However, it is not well established to what degree parameter estimates are affected by model misspecification when applying missing data techniques (MDTs) to incomplete multilevel data. We compare the performance of three MDTs with incomplete hierarchical data. We consider the impact of imputation model misspecification on the quality of parameter estimates by employing multiple imputation under assumptions of a normal model (MI/NM) with two-level cross-sectional data when values are missing at random on the dependent variable at rates of 10%, 30%, and 50%. Five criteria are used to compare estimates from MI/NM to estimates from MI assuming a linear mixed model (MI/LMM) and maximum likelihood estimation to the same incomplete data sets. With 10% missing data (MD), techniques performed similarly for fixed-effects estimates, but variance components were biased with MI/NM. Effects of model misspecification worsened at higher rates of MD, with the hierarchical structure of the data markedly underrepresented by biased variance component estimates. MI/LMM and maximum likelihood provided generally accurate and unbiased parameter estimates but performance was negatively affected by increased rates of MD.     

Sensitivity as a Privileged Predictor of Attachment: A Second Perspective on De Wolff and van IJzendoorn's Meta-analysis

De Wolff and van IJzendoorn's meta‐analysis supported the relation of parental behavior to attachment security; however, they concluded that sensitivity was not the best predictor of attachment security. This secondary analysis of their data re‐examined their conclusion and tested moderators of the relation between sensitivity and attachment, such as socioeconomic status and study methodology. A different grouping of studies combining behavior types of sensitivity, mutuality, and synchrony showed significantly higher correlations with attachment than did other types of maternal behavior. An analysis of a similar dataset of individual correlations defined sensitivity as synchronous, responsive, and appropriate behavior, producing similar results. Tests of moderators validated differences between studies using measures of sensitivity as compared to other measures of maternal behavior. Sensitivity was a weaker predictor of attachment in studies of low‐income families.     

Government Publications

Abstract

To determine whether health sciences faculty are sufficiently knowledgeable about copyright, fair use, and related precepts in their use of materials for teaching and research purposes, librarians at two comparable institutions, the University of Alabama at Birmingham (UAB) and the University of Texas Health Science Center at San Antonio (UTHSCSA), conducted a Web survey regarding copyright knowledge among their respective faculty. Responses were similar from both institutions despite the fact that UTHSCSA faculty had access to a more coordinated copyright education effort. Most respondents self-reported at least a limited familiarity with copyright law and fair use.     

Framing ‘drug prevention’ for young people in contact with the criminal justice system in England: views from practitioners in the field

ABSTRACT

Drawing on the work of Rein and Schon (1993. “Reframing Policy Discourse.” In The Argumentative Turn in Policy Analysis and Planning, edited by F. Fischer, and J. Forester, 145–166. London: UCL Press., 1996. “Frame-Critical Policy Analysis and Frame-Reflective Policy Practice.” Knowledge and Policy: the International Journal of Knowledge Transfer and Utilization 9 (1): 85–104), we explore the ways in which ‘young people’, ‘vulnerability’, ‘risk’, ‘prevention’ and ‘prevention practice’ were defined and framed by practitioners engaged in the design, delivery and commissioning of drug prevention interventions for young people in contact with the criminal justice system. We argue that practitioners describe their work in terms of both a preventative frame – based on a ‘deficit’ model – and a transformative praxis frame, more in line with an increasing shift towards ‘positive youth justice’ where practitioners aspire to actively involve the young person in a process of change. The implications of those, often competing, frames are discussed in relation to the development of prevention approaches and the challenges in designing drugs prevention for this group of young people. The paper is based on interviews and focus groups with thirty-one practitioners in England and is part of the EU funded EPPIC project (Exchanging Prevention Practices on Polydrug Use among Youth in Criminal Justice Systems 2017–2020).     

Social Self‐Control,Externalizing Behavior,and Peer Liking Among Children with ADHD‐CT: A Mediation Model

This study investigated the role of externalizing behavior as a mediator of the relation between social self‐control and peer liking among children with attention‐deficit/hyperactivity disorder‐combined type (ADHD‐CT). A model was proposed whereby externalizing behavior would fully statistically account for the direct relation of social self‐control to peer liking. One hundred seventy‐two children ages 7.0–9.9 years with ADHD‐CT were rated by their teachers regarding their social self‐control and by their parents and teachers regarding their rates of externalizing behavior. Same‐sex classmates provided ratings of overall liking. Structural equation modeling was used to assess the proposed model. Results supported the proposed model of externalizing behavior as fully statistically accounting for the relation of social self‐control to peer liking. This study demonstrated the crucial role that externalizing behaviors play in the social impairment commonly seen among children with ADHD‐CT.
