Abstract. Tide predictions based on tide-gauge observations are not just the astronomical tides; they also contain radiational tides – periodic sea-level changes due to atmospheric conditions and solar forcing. This poses a problem of double-counting for operational forecasts of total water level during storm surges. In some surge forecasting, a regional model is run in two modes: tide only, with astronomic forcing alone; and tide and surge, forced additionally by surface winds and pressure. The surge residual is defined to be the difference between these configurations and is added to the local harmonic predictions from gauges. Here we use the Global Tide and Surge Model (GTSM) based on Delft-FM to investigate this in the UK and elsewhere, quantifying the weather-related tides that may be double-counted in operational forecasts. We show that the global S2 atmospheric tide is captured by the tide-and-surge model and observe changes in other major constituents, including M2. The Lowest and Highest Astronomical Tide levels, used in navigation datums and design heights, are derived from tide predictions based on observations. We use our findings on radiational tides to quantify the extent to which these levels may contain weather-related components.

Assessing the ‘value’ of potential cures can be challenging, as some have suggested that cures may offer distinctive benefits from noncurative treatments. We explore what these – previously unspecified – additional benefits may be. We suggest that three new elements of value seem distinctive to cures: liberation from the identity of being diseased, liberation from the stigma associated with the disease and liberation from the burden of ongoing therapy. However, including additional elements of value in health technology assessment may result in double counting and requires consideration of potential opportunity costs. We suggest health technology assessment should explore the relevance of these three elements of value and may have good reasons to – judiciously – integrate them through the deliberative process.

Abstract Recently, social epistemologists have sought to establish what the governing epistemic relationship should be between novices and experts. In this article, the author argues for, and expands upon, Helen De Cruz’s expert-as-teacher model. For although this model is vulnerable to significant challenges, the author proposes that a specifically extended version can sufficiently overcome these challenges (call this the “extended-expert-as-teacher” model, or the “EEAT” model). First, the author shows the respective weaknesses of three influential models in the literature. Then, he argues the expert-as-teacher model can overcome its weaknesses by adding what he calls the “Authority Clause”, “Advisor Clause”, and “Ex Post Facto Clause” of the EEAT model. After developing a robust account of these clauses, the author entertains three major objections. First, he responds to the charge that the EEAT model is little better than the expert-as-authority model. Second, he responds to a double-counting objection. Lastly, he responds to a pragmatic objection from complexity.
