Citations of Murray Sidman's work in JEAB: Evidence of a long and large contribution

We examined citations of Murray Sidman's publications in the Journal of the Experimental Analysis of Behavior from the journal's inception in 1958 through May 2020. On average, he was cited 35.6 times per year. The rate of citation did not change substantially across time and the cumulative citation count was 2,212. His 10 publications cited most often deal with behavior-analytic research methods, stimulus equivalence, and unsignaled free-operant (or Sidman) avoidance. Our data provide clear evidence of the breadth and depth of Sidman's influence on the experimental analysis of behavior across 7 decades. His contributions were both exceptional and praiseworthy and his legacy will long endure.     

Interpersonal perceptions of personality traits in elite coach-athlete dyads

IntroductionThe extent to which coaches and athletes can effectively work together is an essential consideration in the pursuit of athletic success. This is particularly important at the elite level due to the high pressures on tangible outcomes, such as reaching the podium of a major competition. This study sought to explore and explain how both coaches and athletes identify personality traits in themselves and their partners to manage and maintain a positive relationship.MethodsUsing a mixed methodological design underpinned by critical realism, four elite coach-athlete dyads (four male coaches, one male athlete, three female athletes) were purposefully recruited from a single sport. Each participant completed the 44-item Big Five Inventory (John & Srivastava, 1999) on their own and their partner’s perceived personality traits. The data generated were used to inform the discussions in follow-up, individual semi-structured interviews with all participants.ResultsThe interview data were analysed using thematic analysis, which generated three higher themes and seven lower order themes. The three higher order themes were perceived compatibility, relationship persona and collective personality.ConclusionThe present investigation has identified what coaches and athletes perceive to be the key personality characteristics to manage and maintain a successful working relationship.     

Current issues and new direction in Psychology and Health: Epidemiology and health psychology – please bridge the gap

Epidemiology has and continues to play a vital role in furthering our understanding of risks for disease development. Large scale studies provide the necessary statistical power to identify biological and environmental factors associated with disease onset and severity. However, association does not confirm causality and in theoretical terms, epidemiology is somewhat limited. In this editorial, we argue that bringing together the methodological strengths of epidemiology with the theoretical rigour of psychology enables researchers to go beyond risk-finding and develop causative [or explanatory] models of disease development which pave the way for directed, evidence-based interventions to improve health.     

Young women's contraception use as a contextual and dynamic behaviour: A qualitative study

A number of models of behaviour have been applied to contraception use including subjective expected utility theory and social cognition models. Whilst correlates of contraception use have been identified, the limitations of these models include their failure to consider either contextual factors or changes in contraception use over time. Researchers have called for integrated and dynamic models of contraception use, which can be related to the changing contraception use of individual women and can also be readily operationalised to explore within and between subject differences in contraception use. The present study therefore used a qualitative methodology to explore women's contraceptive histories and to enable women to define the issues from their perspectives, resulting in a model of contraception use that is firmly located within the context of their own lives and allows an investigation of the factors and processes involved in changes in contraception use/non-use over time. This model conceptualises the predictors of contraception use in terms of the meaning and importance of a range of social goals, perceptions of vulnerability and constraints on or facilitators of contraception. Further the dynamic nature of these factors is described and it is illustrated how these core components vary over time according to situation, experience, and new information. The paper outlines the relevance of the findings for different models of decision-making processes and highlights the way that the model addresses the limitations of previous approaches.     

Structure of Al–Co–Ni pentagonal quasicrystal studied by HAADF-STEM and ab initio calculations

Using a combination of atomic-resolution high-angle annular dark-field (HAADF) Z-contrast imaging and ab initio calculations, atomic models of clusters 2 nm in diameter and 0.8 nm in height are proposed for the Al–Co–Ni pentagonal quasicrystal. This quasicrystal has 5-fold symmetry (the so-called 5f state) without superstructures, and is one of numerous modifications of the Al–Co–Ni decagonal quasicrystal. HAADF results reveal that the two-dimensional quasi-periodic lattice contains mainly Penrose pentagonal tiling. The centres within the decorated pentagonal tiles, i.e. the so-called pentagonal super-clusters, show structural characteristics having both a satellite-orbit shape and a pentagon-symmetry shape. The proposed atomic models, based directly on the HAADF images, are subjected to ab initio total energy calculations. After relaxation, the calculations demonstrate that the models with 5-fold symmetry are energetically more favourable than those with 10-fold symmetry.
