    What part of Fides Quaerens don’t you Intellectum ? On the Persistent Philosophical Misunderstanding of Anselm’s Ontological Argument

    A *very* rough draft of a paper on Anselm's "ontological argument" in which I argue that the argument in the Proslogion rests on a robust notion of having "that then which nothing greater can be thought" in one's mind

    The relationship between EQ-5D, HAQ and pain in patients with rheumatoid arthritis: further validation and development of the limited dependent variable, mixture model approach

    Objective To provide robust estimates of EQ-5D as a function of the Health Assessment Questionnaire (HAQ) and pain in patients with rheumatoid arthritis. Method Repeated observations of patients diagnosed with RA in a US observational cohort (n=100,398 observations) who provided data on HAQ, pain on a visual analogue scale and the EQ-5D questionnaire. We use a bespoke mixture modelling approach to appropriately reflect the characteristics of the EQ-5D instrument and compare this to results from linear regression. Results The addition of pain alongside HAQ as an explanatory variable substantially improves explanatory power. The preferred model is a four component mixture. Unlike the linear regression it exhibits very good fit to the data, does not suffer from problems of bias or predict values outside the feasible range. Conclusions It is appropriate to model the relationship between HAQ and EQ-5D but only if suitable statistical methods are applied. Linear models underestimate the QALY benefits, and therefore the cost effectiveness, of therapies. The bespoke mixture model approach outlined here overcomes this problem. The addition of pain as an explanatory variable greatly improves the estimates

    A comparison of direct and indirect methods for the estimation of health utilities from clinical outcomes

    Background: Analysts often need to estimate health state utility values as a function of other outcome measures. Utility values like EQ-5D have several unusual characteristics that make standard statistical methods inappropriate. We have developed a bespoke approach based on mixture models to directly estimate EQ-5D. An indirect method, “response mapping”, first estimates the level on each of the five dimensions of the EQ-5D descriptive system and then calculates the expected tariff score. These methods have never previously been compared. Methods: We use a large observational database of patients diagnosed with Rheumatoid Arthritis (n=100,398 observations). Direct estimation of UK EQ-5D scores as a function of Health Assessment Questionnaire (HAQ), pain and age was performed using a limited dependent variable mixture model. Indirect modelling was undertaken using a set of generalized ordered probit models with expected tariff scores calculated mathematically. Linear regression was reported for comparison purposes. Results: The linear model fits poorly, particularly at the extremes of the distribution. Both the bespoke mixture model and the generalized ordered probit approach offer improvements in fit over the entire range of EQ-5D. Mean average error is 10% and 5% lower compared to the linear model respectively. Root mean squared error is 3% and 2% lower. The mixture model demonstrates superior performance to the indirect method across almost the entire range of pain and HAQ. Limitations: There is limited data from patients in the most extreme HAQ health states. Conclusions: Modelling of EQ-5D from clinical measures is best performed directly using the bespoke mixture model. This substantially outperforms the indirect method in this example. Linear models are inappropriate, suffer from systematic bias and generate values outside the feasible range

    The Manuscripts of Acts from Vatopedi Monastery, Mount Athos, Greece

    Get PDF
    Of the 5,487 manuscripts known today, fewer than half have been studied, yet curiously most have been assigned a text-type. The Byzantine minuscules are among the majority of these manuscripts which have been assigned a text-type even though they have not been studied. Hort\u27s negative assessment of the Byzantine manusrcipts and their neglect by scholars such as Comfort, and K. Aland have caused them to be disregarded. However, until there is proof to the contrary, the Byzantine minuscules should play a meaningful role in the textual criticism of the Greek New Testament. More importantly, before manuscripts are assigned text-types or manuscript groupings, facts about the contents of the manuscripts should be in hand, in order to assure accurate assessment. Only then will textual critics be able to determine the history of the transmission of the Greek New Testament

    Enhancing the area of a Raman atom interferometer using a versatile double-diffraction technique

    Full text link
    IIn this paper we demonstrate a new scheme for Raman transitions which realize a symmetric momentum-space splitting of 4â„Źk4 \hbar k, deflecting the atomic wave-packets into the same internal state. Combining the advantages of Raman and Bragg diffraction, we achieve a three pulse state labelled interferometer, intrinsically insensitive to the main systematics and applicable to all kind of atomic sources. This splitting scheme can be extended to 4Nâ„Źk4N \hbar k momentum transfer by a multipulse sequence and is implemented on a 8â„Źk8 \hbar k interferometer. We demonstrate the area enhancement by measuring inertial forces
