Impact of hostility and withdrawal in interparental conflict on parental emotional unavailability and children's adjustment difficulties

This multimethod, prospective study examined the nature of pathways between interparental hostility and withdrawal, parental emotional unavailability, and subsequent changes in children's internalizing and externalizing behaviors, and school adjustment difficulties over a 3-year period in a sample of 210 mothers, fathers, and 6-year-old children. The results of autoregressive structural equation models indicated that interparental withdrawal had a detrimental impact on all areas of children's adjustment, whereas interparental hostility had an indirect effect on subsequent changes in child adjustment. An intermediary role of parental emotional unavailability in links between interparental withdrawal and hostility and child outcomes was indicated, with specific, differential effects observed for fathers and mothers.     

Creativity as a twenty-first-century competence: an exploratory study of provision and reality

Recently, creativity has begun to be talked about as a twenty-first-century competency [UNESCO (United Nations Educational, Scientific and Cultural Organisation). 2006. The World Conference on Arts Education: Building Creative Capacities for the 21st Century: Working Document, Lisbon, Portugal, 6–9 March 2006. Lisbon: UNESCO]. Several government-endorsed publications have also stressed the importance of fostering creativity in the classroom [Robinson Report. (1999). Great Britain Department for Education and Employment. Department for Culture, Media and Sport. National Advisory Committee on Creativity and Cultural Education. All Our Futures: Creativity and Culture in Education. London: DfEE; DfES. (2004). Excellence and Enjoyment: A Strategy for Primary School. London: DfES; QCA. (2005). Find It! Promote It! London: QCA]. This study aims to explore opportunities to foster creativity following the new National Curriculum’s introduction (DfE (Department for Education). [2013a. National Curriculum for Art & Design. London: DfE; DfE. 2013b. National Curriculum for History. London: DfE; DfE. 2013c. National Curriculum for Science. London: DfE]). It explores provision and attempts to go beyond this into daily classroom practices by interviewing teachers. Analysis indicates a wide variation in terms of in-school provision. Certain schemes of work may be more successful at fostering creativity and that relying purely on the National Curriculum can hinder opportunities for creativity. Teacher responses indicate that they value creativity but find it hard to accurately describe incidents of creativity being fostered and teaching creatively is often confused for teaching for creativity. Training has been designed to address this, although a pervading emphasis on schools’ performativity will mean creativity is not embedded into daily learning to the extent it can be a twenty-first-century competence unless there is a major policy change.     

When neighboring disciplines fail to learn from each other: The case of innovation and project management research

As knowledge production becomes more specialized, studying complex and multi-faceted empirical realities becomes more difficult. This has created a growing need for cross-fertilization and collaboration between research disciplines. According to prior studies, the sharing of concepts, ideas and empirical domains with other disciplines may promote cross-fertilization. We challenge this one-sided view. Based on an analysis of the parallel development of the neighboring disciplines of innovation studies and project management, we show that the sharing of concepts and empirical domains can have ambivalent effects. Under conditions of ideological distancing, shared concepts and domains will be narrowly assimilated ? an effect we call ‘encapsulation’ – which creates an illusion of sharing, while promoting further self-containment. By comparison, reflexive meta-theories and cross-disciplinary community-building will enable a form of sharing that promotes cross-fertilization. Our findings inform research on research specialization, cross-fertilization and effectiveness of interdisciplinary collaboration.     

Optimization of Maximal Rate of Heart Rate Increase Assessment in Runners

Purpose: Correlations between fatigue-induced changes in exercise performance and maximal rate of heart rate (HR) increase (rHRI) may be affected by exercise intensity during assessment. This study evaluated the sensitivity of rHRI for tracking performance when assessed at varying exercise intensities. Method: Performance (time to complete a 5-km treadmill time-trial [5TTT]) and rHRI were assessed in 15 male runners following 1 week of light training, 2 weeks of heavy training (HT), and a 10-day taper (T). Maximal rate of HR increase (measured in bpm·s^?1) was the first derivative maximum of a sigmoidal curve fit to HR data recorded during 5 min of running at 8 km·h^?1 (rHRI_8km·h^?1), and during subsequent transition to 13 km·h^?1 (rHRI_{8–13km·h^?1}) for a further 5 min. Results: Time to complete a 5-km treadmill time-trial was likely slower following HT (effect size ± 90% confidence interval = 0.16 ± 0.06), and almost certainly faster following T (–0.34 ± 0.08). Maximal rate of HR increase during 5 min of running at 8 km·h^?1 and rHRI_{8–13km·h^?1} were unchanged following HT and likely increased following T (0.77 ± 0.45 and 0.66 ± 0.62, respectively). A moderate within-individual correlation was found between 5TTT and rHRI_8km·h^?1 (r value ± 90% confidence interval = –.35 ± .32). However, in a subgroup of athletes (n = 7) who were almost certainly slower to complete the 5TTT (4.22 ± 0.88), larger correlations were found between the 5TTT and rHRI_8km·h^?1 (r = –.84 ± .22) and rHRI_{8–13km·h^?1} (r = –.52 ± .41). Steady-state HR during rHRI assessment in this group was very likely greater than in the faster subgroup (≥ 1.34 ± 0.86). Conclusion(s): The 5TTT performance was tracked by both rHRI_8km·h^?1 and rHRI_{8–13km·h^?1}. Correlations between rHRI and performance were stronger in a subgroup of athletes who exhibited a slower 5TTT. Individualized workloads during rHRI assessment may be required to account for varying levels of physical conditioning.
