Establishing the Effects of Quality in Early Childhood: Comparing Evidence from England

This is the final version. Available from Early Education via the URL in this record.This occasional paper examines the robustness of a paper published by Blanden, Hansen and McNally in February 2017 which sought to investigate the effects of quality within early education and care settings in England (Quality in Early Years Settings and Children's School Achievement, CEP Discussion Paper 1468, The London School of Economics). The authors question the validity of the conclusions reached by Blanden et al about the impact of quality in early childhood education in England

Putting Brexit into perspective: the effect of the Eurozone and migration crises and Brexit on Euroscepticism in European states

This paper examines the link between recent EU crises and the development of party-based Euroscepticism across Europe. It draws on data from expert surveys with qualitative data to outline the way in which we can empirically see the link between the impacts of the crises in European states, and how far, and in what ways, Euroscepticism has been mobilized by political parties in those states. It identifies four main frames through which the EU is contested in European states which focus on: economic factors, immigration, democracy/sovereignty and national factors. It also shows that there has been a clear difference between the impacts of the different crises. While the Eurozone crisis had a particularly powerful effect in the party systems of those countries most affected by the bailout packages and the migration crisis had a particularly strong effect on party politics in the post-communist states of central Europe, Brexit has had a very limited impact on national party politics, although this may change in the longer-term

A study of the long-term influence of early childhood education and care on the risk for developing special educational needs

Preschool programs were already viewed in the 1960s as important for preventing or correcting the cognitive deficits found in disadvantaged children (Weikart, 1966 reprinted 2016). This paper explores the possible influence of group-based early childhood education and care (ECEC), offered to the general population, on the risk for special educational needs (SEN) drawing from a large-scale longitudinal study in England. Overall, the results point towards the provision of high quality ECEC for children significantly decreasing the risk of SEN in later years. Children who had high quality (or effective) ECEC showed a 40-60% lower level of risk for cognitive SEN. The results are not so clear-cut for socio-emotional outcomes but overall the pattern is similar with children who had high quality (or effective) ECEC showing a 10-30% lower risk of developing socio-emotional SEN

Measurement of the 18Ne(a,p_0)21Na reaction cross section in the burning energy region for X-ray bursts

The 18Ne(a,p)21Na reaction provides one of the main HCNO-breakout routes into the rp-process in X-ray bursts. The 18Ne(a,p_0)21Na reaction cross section has been determined for the first time in the Gamow energy region for peak temperatures T=2GK by measuring its time-reversal reaction 21Na(p,a)18Ne in inverse kinematics. The astrophysical rate for ground-state to ground-state transitions was found to be a factor of 2 lower than Hauser-Feshbach theoretical predictions. Our reduced rate will affect the physical conditions under which breakout from the HCNO cycles occurs via the 18Ne(a,p)21Na reaction.Comment: 5 pages, 3 figures, accepted for publication on Physical Review Letter

DNA polymorphism underlying allozyme variation at a malic enzyme locus (mMEP-2*) in Atlantic salmon (Salmo salar L.)

A non-synonymous single nucleotide polymorphism (SNP) underlies a diallelic allozyme polymorphism at the mitochondrial NADP-dependent mMEP-2* locus in Atlantic salmon (\textit{Salmo salar} L.). The resultant amino acid substitution, which alters the charge of the allelic products, matches the differential mobility of the two allozyme alleles, while allozyme and SNP assays revealed genotyping concordance in 257 of 258 individuals. A single mismatch, homozygous allozyme vs heterozygote SNP, suggests the presence of a second, less common null allele

The Impact of Escaped Farmed Atlantic Salmon (Salmo salar L.) on Catch Statistics in Scotland

In Scotland and elsewhere, there are concerns that escaped farmed Atlantic salmon (Salmo salar L.) may impact on wild salmon stocks. Potential detrimental effects could arise through disease spread, competition, or inter-breeding. We investigated whether there is evidence of a direct effect of recorded salmon escape events on wild stocks in Scotland using anglers' counts of caught salmon (classified as wild or farmed) and sea trout (Salmo trutta L.). This tests specifically whether documented escape events can be associated with reduced or elevated escapes detected in the catch over a five-year time window, after accounting for overall variation between areas and years. Alternate model frameworks were somewhat inconsistent, however no robust association was found between documented escape events and higher proportion of farm-origin salmon in anglers' catch, nor with overall catch size. A weak positive correlation was found between local escapes and subsequent sea trout catch. This is in the opposite direction to what would be expected if salmon escapes negatively affected wild fish numbers. Our approach specifically investigated documented escape events, contrasting with earlier studies examining potentially wider effects of salmon farming on wild catch size. This approach is more conservative, but alleviates some potential sources of confounding, which are always of concern in observational studies. Successful analysis of anglers' reports of escaped farmed salmon requires high data quality, particularly since reports of farmed salmon are a relatively rare event in the Scottish data. Therefore, as part of our analysis, we reviewed studies of potential sensitivity and specificity of determination of farmed origin. Specificity estimates are generally high in the literature, making an analysis of the form we have performed feasible

Effective emotion regulation strategies improve fMRI and ECG markers of psychopathology in panic disorder: Implications for psychological treatment action

© 2015 Macmillan Publishers Limited. All rights reserved. Impairments in emotion regulation are thought to have a key role in the pathogenesis of anxiety disorders, but the neurobiological underpinnings contributing to vulnerability remain poorly understood. It has been a long-held view that exaggerated fear is linked to hyperresponsivity of limbic brain areas and impaired recruitment of prefrontal control. However, increasing evidence suggests that prefrontal-cortical networks are hyperactive during threat processing in anxiety disorders. This study directly explored limbic-prefrontal neural response, connectivity and heart-rate variability (HRV) in patients with a severe anxiety disorder during incidental versus intentional emotion regulation. During 3 Tesla functional magnetic resonance imaging, 18 participants with panic disorder and 18 healthy controls performed an emotion regulation task. They either viewed negative images naturally (Maintain), or they were instructed to intentionally downregulate negative affect using previously taught strategies of cognitive reappraisal (Reappraisal). Electrocardiograms were recorded throughout to provide a functional measure of regulation and emotional processing. Compared with controls, patients showed increased neural activation in limbic-prefrontal areas and reduced HRV during incidental emotion regulation (Maintain). During intentional regulation (Reappraisal), group differences were significantly attenuated. These findings emphasize patients' ability to regulate negative affect if provided with adaptive strategies. They also bring prefrontal hyperactivation forward as a potential mechanism of psychopathology in anxiety disorders. Although these results challenge models proposing impaired allocation of prefrontal resources as a key characteristic of anxiety disorders, they are in line with more recent neurobiological frameworks suggesting that prefrontal hyperactivation might reflect increased utilisation of maladaptive regulation strategies quintessential for anxiety disorders
