Research note: Measuring cultural values - The case of residents' attitudes to the Saltaire Festival
This research note discusses the findings and methodological issues arising from a cultural values survey of residents, particularly in relation to civic pride. In addition to offering insights to the particular case - the Saltaire Festival in the north of England - it provides an approach that might be used elsewhere
Further observations on the pathology of bluetongue in sheep

Gone with the wind: dune provenance and sediment recycling in the northern Rubâ al-Khali, United Arab Emirates
The Rubâal-Khali dune field in southern Arabia is the largest sand sea in the world. Deciphering thepalaeoenvironmental history of the Rubâal-Khali is critical to understanding its role as a barrier to human migration, dispersaland settlement. To determine sediment provenance and transport pathways, we combined data from a geological mappingproject with traditional heavy mineral optical point-counting methods, heavy mineral geochemical fingerprinting and detritalzircon UâPb geochronology of Miocene and Quaternary sediments in the United Arab Emirates (UAE). Detrital zircon UâPbage spectra demonstrate that most Neogene and Quaternary sediments in the UAE are ultimately sourced from the PrecambrianArabian Shield. Heavy mineral and geochemical signatures indicate that the dune sands are locally recycled from the deflationof Miocene sandstones and Quaternary siliciclastic palaeodunes exposed along the Arabian Gulf coast, whereas carbonatepalaeodunes along the Gulf coast are derived from the deflation of sediments deposited by the TigrisâEuphrates River system inthe Gulf during Pleistocene lowstands. In the eastern Emirates, Miocene and Quaternary alluvial fan deposits emanating fromthe Hajar Mountains have an ophiolitic heavy mineral signature. The data reveal new insights into the origin and developmentof the Rubâal-Khali dune field

Research Review: Do parent ratings of infant negative emotionality and selfâregulation predict psychopathology in childhood and adolescence? A systematic review and metaâanalysis of prospective longitudinal studies
Background
Identifying lowâcost and easy to implement measures of infant markers of later psychopathology may improve targeting of early intervention for prevention. Because of their early manifestation, relative stability and overlap with constructs central to affectâbased dimensions of child and adolescent psychopathology, negative emotionality and selfâregulation have been the focus of this research. We conducted a metaâanalysis of longitudinal studies examining the prospective association between infant temperament measured with parent ratings and child/adolescent psychopathology.
Methods
A systematic literature search for prospective longitudinal studies, which included measures of questionnaireâassessed infant temperament (negative emotionality, selfâregulation, behavioural inhibition, surgency/extraversion, activity level) and symptoms of child or adolescent mental health (externalising, internalising) and neurodevelopmental problems (attention deficit/hyperactivity disorder [ADHD], autism spectrum disorder [ASD]), was conducted. Standardised estimates of association were calculated and pooled in metaâanalyses.
Results
Twentyâfive studies (n = 28,425) met inclusion criteria. Small associations were seen between psychopathology aggregated across all domains and infant negative emotionality (r = .15; p < .001) and selfâregulation (r = â.19; p = .007). Effects were also significant but weaker for behavioural inhibition (r = .10; p = .027) and activity level (r = .08; p = .016). Surgency/extraversion was not significantly associated with psychopathology in general (r = â.04; p = .094); however, it was negatively associated with ASD (r = â.10, p = .015). Significant correlations were observed with some outcomes isomorphic with predictors, internalising problems and behavioural inhibition (r = .10; p = .013), ADHD symptoms and activity level (r = .19; p = .009).
Conclusion
Questionnaireâbased assessments of infant negative emotionality may have transdiagnostic potential to contribute to a risk index of later childhood psychopathology. Behavioural inhibition, surgency/extraversion and activity ratings may provide more specific predictive power. More data from prospective studies are required before the potential of selfâregulation and surgency/extraversion can be properly gauged
