Intergovernmental Relations in Scotland: what was the SNP effect?

In Scotland, the formation of a minority government in 2007 by the Scottish National Party (SNP) provided the potential for profound changes in intergovernmental relations. This followed eight years of a Scottish Labour-led coalition government characterised by a low-key and informal relationship with the UK Labour government. From 1999 to 2007, discussions were conducted informally and almost entirely through political parties and executives (ministers and civil servants). Although formal mechanisms for negotiation and dispute resolution existed-including the courts, concordats and Joint Ministerial Committees-they were used rarely. The Scottish Executive also played a minimal role in EU policy-making. Yet, an ‘explosive' new era of relations between the Scottish and UK governments did not arrive in tandem with the new era of party incongruence. The aim of this article is to explore these issues by asking two main questions: why were formal mechanisms used so rarely from 1999 to 2007, and what factors produced muted rather than problematic IGR in the third parliamentary session, between 2007 and 2011

Schema-conformant memories are preferentially consolidated during REM sleep

Memory consolidation is most commonly described by the standard model, which proposes an initial binding role for the hippocampus which diminishes over time as intracortical connections are strengthened. Recent evidence suggests that slow wave sleep (SWS) plays an essential role in this process. Existing animal and human studies have suggested that memories which fit tightly into an existing knowledge framework or schema might use an alternative consolidation route in which the medial prefrontal cortex takes on the binding role. In this study we sought to investigate the role of sleep in this process using a novel melodic memory task. Participants were asked to remember 32 melodies, half of which conformed to a tonal schema present in all enculturated listeners, and half of which did not fit with this schema. After a 24-h consolidation interval, participants were asked to remember a further 32 melodies, before being given a recognition test in which melodies from both sessions were presented alongside some previously unheard foils. Participants remembered schema-conformant melodies better than non-conformant ones. This was much more strongly the case for consolidated melodies, suggesting that consolidation over a 24-h period preferentially consolidated schema-conformant items. Overnight sleep was monitored between the sessions, and the extent of the consolidation benefit for schema-conformant items was associated with both the amount of REM sleep obtained and EEG theta power in frontal and central regions during REM sleep. Overall our data suggest that REM sleep plays a crucial role in the rapid consolidation of schema-conformant items. This finding is consistent with previous results from animal studies and the SLIMM model of Van Kesteren, Ruiter, Fernández, and Henson (2012), and suggest that REM sleep, rather than SWS, may be involved in an alternative pathway of consolidation for schema-conformant memories.

Identification of a selective G1-phase benzimidazolone inhibitor by a senescence-targeted virtual screen using artificial neural networks

Cellular senescence is a barrier to tumorigenesis in normal cells and tumour cells undergo senescence responses to genotoxic stimuli, which is a potential target phenotype for cancer therapy. However, in this setting, mixed-mode responses are common with apoptosis the dominant effect. Hence, more selective senescence inducers are required. Here we report a machine learning-based in silico screen to identify potential senescence agonists. We built profiles of differentially affected biological process networks from expression data obtained under induced telomere dysfunction conditions in colorectal cancer cells and matched these to a panel of 17 protein targets with confirmatory screening data in PubChem. We trained a neural network using 3517 compounds identified as active or inactive against these targets. The resulting classification model was used to screen a virtual library of ~2M lead-like compounds. 147 virtual hits were acquired for validation in growth inhibition and senescence-associated β-galactosidase (SA-β-gal) assays. Among the found hits a benzimidazolone compound, CB-20903630, had low micromolar IC50 for growth inhibition of HCT116 cells and selectively induced SA-β-gal activity in the entire treated cell population without cytotoxicity or apoptosis induction. Growth suppression was mediated by G1 blockade involving increased p21 expression and suppressed cyclin B1, CDK1 and CDC25C. Additionally, the compound inhibited growth of multicellular spheroids and caused severe retardation of population kinetics in long term treatments. Preliminary structure-activity and structure clustering analyses are reported and expression analysis of CB-20903630 against other cell cycle suppressor compounds suggested a PI3K/AKT-inhibitor-like profile in normal cells, with different pathways affected in cancer cells

Is Scotland a Westminster-style Majoritarian Democracy or a Scandinavian-style Consensus Democracy? A Comparison of Scotland, the UK and Sweden

What is the 'dominant model' of British policymaking? Comparing majoritarian and policy community ideas

The aim of this article is to help identify the fundamental characteristics of the British policymaking system. It highlights an enduring conflict of interpretation within the literature. On the one hand, most contemporary analysts argue that the ‘Westminster model' is outmoded and that it has been replaced by modern understandings based on ‘governance'. On the other, key ideas associated with the Westminster model, regarding majoritarian government and policy imposition, are still in good currency in the academic literature, which holds firm to Lijphart's description of the United Kingdom as a majoritarian democracy. These very different understandings of British government are both commonly cited, but without much recognition that their conclusions may be mutually incompatible. To address this lack of comparison of competing narratives, the article outlines two main approaches to describe and explain the ‘characteristic and durable' ways of doing things in Britain: the ‘policy styles' literature initiated by Richardson in Policy Styles in Western Europe and the Lijphart account found in Democracies and revised in 1999 as Patterns of Democracy. The article encourages scholars to reject an appealing compromise between majoritarian and governance accounts
