Objective:
To explore the #SugarTax debate on Twitter to assess actors involved, their connections and the topics being discussed during the implementation and first anniversary of the UK Soft Drink Industry Levy.
Design:The structure of the #SugarTax debate on Twitter was assessed using social network analysis. The actors involved, their connections and the topics of discussion taking place were also explored using content, sentiment and thematic analyses.
Setting:Twitter between 2017 and 2019.
Participants:Twitter users engaging in discussions relating to the hashtag ‘SugarTax’.
Results:Tweets (n 5366) posted between 5 August 2017 and 7 May 2019 containing #SugarTax were downloaded from Twitter using Network Overview for Discovery and Exploration in Excel. The network included 1883 users, with 686 unique edges and 4679 edges with duplicates. The majority of tweets were negative in sentiment, when assessed by both automatic (64 %, n 141) and manual sentiment analysis (52 %, n 115) methods. Nine key themes were identified and grouped into two groups according to ‘support for a sugar or SSB tax’ or ‘opposition for a sugar or SSB tax’.
Conclusions:Twitter was used as a platform for debating the benefits and limitations of sugar-sweetened beverage taxes. The findings indicate that numerous actors are involved in the debates on Twitter, with advocates and lobbyists using the platform to raise support for their campaigns and reshape public perceptions. The findings and the methods used may be of interest to policymakers as well as to academics and members of the public looking to explore and engage in policy debates.

Objective:
The National Child Measurement Programme (NCMP) is a mandatory initiative delivered in England to children in Reception and Year 6. To date, no research has explored the methods used to deliver the NCMP by Local Government Authorities (LGA) across England.
Design:An online survey was administered between February 2018 and May 2018 to explore the delivery of the NCMP across the 152 LGA in England and disseminated using non-probability convenience sampling.
Setting:LGA received an anonymous link to the survey.
Participants:A total of 92 LGA participated in the survey.
Results:Most LGA who responded provide result feedback (86 %), a proactive follow-up (71 %) and referrals to services (80 %). Additionally, 65 % of the authorities tailor Public Health England specimen result letters to suit their needs, and 84 % provide attachments alongside. Out of 71 % of LGA who provide proactive follow-up, 19 (29 %) provide the proactive follow-up only to upper weight categories and only 4 (6 %) include Healthy Weight category with other categories in proactive follow-up. Regarding the service availability for children, out of 80 % of LGA who indicated that services are available, 32 (43 %) targeted solely upper weight categories, while the other 42 (57 %) offered services across all weight categories. Finally, most LGA (88 %) commission providers to manage various parts of the NCMP.
Conclusions:The results show that LGA in England localise the NCMP. Further guidance regarding standards of best practice would help LGA to find the most suitable localisation out of various options that exist across other LGA.

Objective:
News media play a role in politics through the portrayal of policies, influencing public and policymaker perceptions of appropriate solutions. This study explored the portrayal of sugar and sugar-sweetened beverage (SSB) taxes in UK national newspapers. Findings aid understanding of the role newspapers play in shaping understanding and acceptance of policies such as the UK Soft Drink Industry Levy (SDIL).
Design:Articles discussing sugar or SSB taxes published in six UK national newspapers between 1 April 2016 and 1 May 2019 were retrieved from the LexisNexis database. Articles were thematically analysed to reveal policy portrayal.
Setting/Participants:Analysis of UK newspaper articles.
Results:Two hundred and eighty-six articles were assessed. Sugar and SSB taxes were discussed across the sample period but publication peaked at SDIL announcement and introduction. Themes were split according to support for or opposition to taxation. Supportive messaging consistently highlighted the negative impacts of sugar on health and the need for complex actions to reduce sugar consumption. Opposing messages emphasised individual responsibility for health and the unfairness of taxation both for organisations and the public.
Conclusions:Sugar and SSB taxes received considerable media attention between 2016 and 2019. All newspapers covered arguments in support of and opposition to taxation. Health impacts of excess sugar and the role of the soft drink industry in reducing sugar consumption were prevalent themes, suggesting a joined-up health advocacy approach. Industry arguments were more varied, suggesting a less collaborative argument. Further research should investigate how other media channels portray taxes such as the SDIL.

Under the European Union’s Solvency II regulations, insurance firms are required to use a one-year VaR (Value at Risk) approach. This involves a one-year projection of the balance sheet and requires sufficient capital to be solvent in 99.5% of outcomes. The Solvency II Internal Model risk calibrations require annual changes in market indices/term structure for the estimation of risk distribution for each of the Internal Model risk drivers. This presents a significant challenge for calibrators in terms of:
Robustness of the calibration that is relevant to the current market regimes and at the same time able to represent the historically observed worst crisis;
Stability of the calibration model year on year with arrival of new information.
The above points need careful consideration to avoid credibility issues with the Solvency Capital Requirement (SCR) calculation, in that the results are subject to high levels of uncertainty.
For market risks, common industry practice to compensate for the limited number of historic annual data points is to use overlapping annual changes. Overlapping changes are dependent on each other, and this dependence can cause issues in estimation, statistical testing, and communication of uncertainty levels around risk calibrations.
This paper discusses the issues with the use of overlapping data when producing risk calibrations for an Internal Model. A comparison of the overlapping data approach with the alternative non-overlapping data approach is presented. A comparison is made of the bias and mean squared error of the first four cumulants under four different statistical models. For some statistical models it is found that overlapping data can be used with bias corrections to obtain similarly unbiased results as non-overlapping data, but with significantly lower mean squared errors. For more complex statistical models (e.g. GARCH) it is found that published bias corrections for non-overlapping and overlapping datasets do not result in unbiased cumulant estimates and/or lead to increased variance of the process.
In order to test the goodness of fit of probability distributions to the datasets, it is common to use statistical tests. Most of these tests do not function when using overlapping data, as overlapping data breach the independence assumption underlying most statistical tests. We present and test an adjustment to one of the statistical tests (the Kolmogorov Smirnov goodness-of-fit test) to allow for overlapping data.
Finally, we explore the methods of converting “high”-frequency (e.g. monthly data) to “low”-frequency data (e.g. annual data). This is an alternative methodology to using overlapping data, and the approach of fitting a statistical model to monthly data and then using the monthly model aggregated over 12 time steps to model annual returns is explored. There are a number of methods available for this approach. We explore two of the widely used approaches for aggregating the time series.

The Teouma site, on Efate in central Vanuatu, was uncovered during quarrying in 2003 and has proved to be one of the most significant discoveries to date for the colonisation of Remote Oceania. Not only did it bring to light a fine assemblage of the famously diagnostic Lapita ceramics, but a cemetery of more than 25 individuals along with the pots. The skeletons offer an opportunity to investigate the origins of the ‘Lapita people’ who first appeared in the Bismarck archipelago around 3300 years ago and rapidly moved through island Melanesia and Western Polynesia over the next few centuries.

We examined the relationship between nocturnal respiratory disturbance and learning and compared learning in children with and without nocturnal respiratory disturbance. Subjects were 149 participants in a prospective cohort study examining sleep in children ages 6–12: The Tucson Children's Assessment of Sleep Apnea study (TuCASA). Sleep was assessed via home polysomnography. Intelligence, learning and memory, and academic achievement were assessed. Parents rated attention. Group comparisons were used to test the hypothesis that the group with an apnea/hypopnea index (AHI) of 5 or more (n = 77) would have weaker performance than the group with AHI less than 5 (n = 72). The group with AHI of 5 or more had weaker learning and memory though differences between groups decreased when arousals were taken into account. There was a greater percentage of Stage 1 sleep in the AHI 5 or more group, and Stage 1 percentage was negatively related to learning and memory in the sample (n = 149). There were negative relationships between AHI and immediate recall, Full Scale IQ, Performance IQ, and math achievement. Hypoxemia was associated with lower Performance IQ. Thus, findings suggest that nocturnal respiratory disturbance is associated with decreased learning in otherwise healthy children, that sleep fragmentation adversely impacts learning and memory, and that hypoxemia adversely influences nonverbal skills.
