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.     

Generational Differences as a Determinant of Women's Perspectives on Commitment

Differences between 116 graduate and undergraduate women, representing 4 generations (i.e., Baby Boomers, Transitionals, Generation Xers, and Millennials), were studied to categorize earliest awareness and definitions of commitment in relationships. More than 63% of participants in each generation viewed relationship commitment in terms of constraints rather than attractions.     

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.     

Dementia and suicidal behavior

Behavioral and psychological symptoms of dementia, including depression, might complicate the course of the disorder additionally. Dementia is more frequent in older people and suicide rates are higher in later life than in any other age group. To explore the phenomenology of suicidal behavior in patients with dementia, we searched electronic databases and key journals for original research and review articles on suicide in demented patients using the search terms “suicide, suicidal behavior, dementia, Alzheimer disease, and old age”. Although cognitive impairment could result in a diminishing ability to think flexibly and to solve problems or to cope with conflict, in the early stage of dementia such impairments are absent or mild, and suicidal behavior might be expected, especially following diagnosis. In addition, personality changes based on declining cognitive capacity and the neurochemical imbalances described in late-life depression and in dementia may predispose patients to aggressive or impulsive acts, such as suicide attempt. The literature on suicidal behavior and dementia highlights the need for further research in this area.     

The role of mother–child and teacher–child relationship on academic achievement

Robust findings have highlighted the importance of early cognitive abilities for academic performance. However, little is known about the role played by relational variables. In this longitudinal study, we examined children’s relationship with their mothers and teachers as predictors of later academic achievement. We addressed this issue following a group of 45 Italian children (29 boys) from the last year of preschool (mean age: five years and six months) until Year 4 of primary school (mean age: nine years and six months). Results showed that mother–child relationship at age 5 and teacher–child relationship at age 7 correlate with children’s academic achievement at age 9, controlling for early background and verbal abilities. Further analyses showed that teacher–child conflict partially mediates the relationship between early mother–child conflict and children’s later academic achievement. Mechanisms by which relational variables influence learning outcomes are 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.
