A reanalysis of the CARIN theory of conceptual combination

The competition among relations in nominals (CARIN) theory of conceptual combination (C. L. Gagné & E. J. Shoben, 1997) proposes that people interpret nominal compounds by selecting a relation from a pool of competing alternatives and that relation availability is influenced by the frequency with which relations have been previously associated with the modifying concept. The current authors derived relation frequencies by using a sample of compounds occurring in the British National Corpus and compared them with those derived by Gagné and Shoben. The authors demonstrated that the original relation frequencies are unrepresentative and that Gagne' and Shoben's technique for dichotomizing them into high and low is unreliable. In addition, the authors revealed anomalies in the mathematical instantiation of the CARIN model and showed that it does not provide evidence for competition among relations.     

Integrating and Enacting ‘Social and Ethical Issues’ in Nanotechnology Practices

The integration of nanotechnology’s ‘social and ethical issues’ (SEI) at the research and development stage is one of the defining features of nanotechnology governance in the United States. Mandated by law, integration extends the field of nanotechnology to include a role for the “social”, the “public” and the social sciences and humanities in research and development (R&D) practices and agendas. Drawing from interviews with scientists, engineers and policymakers who took part in an oral history of the “Future of Nanotechnology” symposium at the Cornell NanoScale Facility, this article examines how nanotechnology’s ‘social and ethical issues’ are brought to life by these practitioners. From our analysis, three modes of enactment emerge: enacting SEI as obligations and problems-to-be-solved, enacting SEI by ‘not doing it’ in the laboratory, and enacting SEI as part of scientific practice. Together they paint a complex picture where SEI are variously defined, made visible or invisible, included and excluded, with participants showing their skill at both boundary-work (Gieryn Am Sociol Rev 48:781–795, 1983, 1999) and at integration. We conclude by reflecting on what this may mean for the design and implementation of SEI integration policies, suggesting that we need to transform SEI from obligations into ‘matters of care’ (Puig de la Bellacasa Soc Stud Sci 41(1):85–106, 2011) that tend to existing relationalities between science and society and implicate practitioners themselves.     

Direct observation of intergranular stress fields in polycrystalline materials

The ability to measure interparticle stress fields is crucial for a number of scientific fields. Detailed knowledge of such interaction stresses can shed light on a number of phenomena such as the fracture mechanics of polycrystalline materials, the mechanics of granular media, and crystallization process of microspheres and nanospheres. In this letter we report the use of a new micro-Raman-spectroscopy-based technique to measure directly the intergranular stress fields in polycrystalline systems. Using Raman active tracers (50Å graphite crystals) dispersed in the system, the technique was shown to be applicable for non-Raman-active polycrystalline systems (e.g. metals). For the first time, stresses within and around individual grains has been monitored in situ as the global system stress was increased to system failure. The effects of grain orientation and shape are monitored and discussed.     

Assessing the Factorial Validity of the Attitudes and Belief Scale 2-Abbreviated Version: A Call for the Development a Gold Standard Method of Measuring Rational and Irrational Beliefs

Rational emotive behaviour therapy (REBT) does not possess a measure of rational and irrational beliefs that meets internationally recognised standards for acceptable psychometric properties. Without such a measure the theory/practice of REBT cannot be rigorously evaluated, thus undermining its scientific veracity. The current study investigates the validity and reliability of a recently developed measure of rational and irrational beliefs: the Attitudes and Belief Scale 2-Abbreviated Version (ABS-2-AV). University students from three countries completed the ABS-2-AV (N = 397). An alternative models framework using confirmatory factor analysis indicated that a theoretically consistent eight-factor model of the ABS-2-AV provided the best fit of the data. A number of post hoc modifications were required in order to achieve acceptable model fit results, and these modifications revealed important methodological limitations with the ABS-2-AV. Results indicated that the validity of the ABS-2-AV was undermined due to items measuring both the psychological process of interest (rational and irrational beliefs) and the context in which these beliefs processes are presented. This is a serious methodological limitation of the ABS-2 and all questionnaires derived from it, including the ABS-2-AV. This methodological limitation resulted in the ABS-2-AV possessing poor internal reliability. These limitations are discussed in relation to the broader REBT literature and the impact such problems have on research and practice. A call is made for REBT researchers to come together to develop a “gold standard” method of assessing rational and irrational beliefs that meets international standard for psychometric excellence.     

Effects of video modeling on treatment integrity of behavioral interventions

We examined the effects of individualized video modeling on the accurate implementation of behavioral interventions using a multiple baseline design across 3 teachers. During video modeling, treatment integrity improved above baseline levels; however, teacher performance remained variable. The addition of verbal performance feedback increased treatment integrity to 100% for all participants, and performance was maintained 1 week later. Teachers found video modeling to be more socially acceptable with performance feedback than alone, but rated both positively.     

Decreasing household television time: a pilot study of a combined behavioral and environmental intervention

Excessive TV viewing is associated with weight gain across the lifespan; thus developing strategies to decrease household viewing time may be an effective obesity prevention approach. This pilot study (n = 6 families) examined the feasibility and short‐term impact of a 2‐pronged environmental plus behavioral approach designed to reduce TV time in the entire family. The environmental manipulation involved placing TV Allowances (programmed to turn off power after family members had watched 75% of their baseline hours) on all TVs in the home. A kit with behavioral strategies for reducing TV time was also sent to the home each week and family members self‐monitored viewing time. Viewing was objectively assessed with the TV Allowances at baseline and at 8 weeks. A significant decrease in objectively measured TV viewing hours was observed, t(5) = 3.1, p = 0.03, 29.8 ± 10.3 versus 14.9 ± 6.0 h (equivalent of decreasing from 7.5 to 3.7 h per day). Fifty percent of families reduced their viewing time by ≥50%. The acceptability of the intervention was high, with 100% of families reporting they would recommend the TV Allowances to others. Further research is needed to test the long‐term efficacy of the program and its impact on weight. Copyright © 2006 John Wiley & Sons, Ltd.
