We have previously shown that higher intake of cruciferous vegetables is inversely associated with carotid artery intima-media thickness. To further test the hypothesis that an increased consumption of cruciferous vegetables is associated with reduced indicators of structural vascular disease in other areas of the vascular tree, we aimed to investigate the cross-sectional association between cruciferous vegetable intake and extensive calcification in the abdominal aorta. Dietary intake was assessed, using a FFQ, in 684 older women from the Calcium Intake Fracture Outcome Study. Cruciferous vegetables included cabbage, Brussels sprouts, cauliflower and broccoli. Abdominal aortic calcification (AAC) was scored using the Kauppila AAC24 scale on dual-energy X-ray absorptiometry lateral spine images and was categorised as ‘not extensive’ (0–5) or ‘extensive’ (≥6). Mean age was 74·9 (sd 2·6) years, median cruciferous vegetable intake was 28·2 (interquartile range 15·0–44·7) g/d and 128/684 (18·7 %) women had extensive AAC scores. Those with higher intakes of cruciferous vegetables (>44·6 g/d) were associated with a 46 % lower odds of having extensive AAC in comparison with those with lower intakes (<15·0 g/d) after adjustment for lifestyle, dietary and CVD risk factors (ORQ4 v. Q1 0·54, 95 % CI 0·30, 0·97, P = 0·036). Total vegetable intake and each of the other vegetable types were not related to extensive AAC (P > 0·05 for all). This study strengthens the hypothesis that higher intake of cruciferous vegetables may protect against vascular calcification.
The growing prominence of comparative political theory has inspired extensive and fruitful methodological reflection, raising important questions about the procedures that political theorists should apply when they select texts for study, interpret their passages, and assess their arguments. But, notably, comparative political theorists have mainly rejected the comparative methods used in the subfield of comparative politics, because they argue that applying the comparative method would compromise both the interpretive and the critical projects that comparative political theory should pursue. In this article, I describe a comparative approach for the study of political ideas that offers unique insight into how the intellectual and institutional contexts that political thinkers occupy influence their ideas. By systematically describing how political thinking varies across time and over space in relation to the contexts within which political thinkers live and work, the comparative method can serve as the foundation for both deconstructive critiques, which reveal the partial interests that political ideas presented as universally advantageous actually serve, and reconstructive critiques, which identify particular thinkers or traditions of political thought that, because of the contexts in which they developed, offer compelling critical perspectives on existing political institutions.
This article compares two recent memory controversies in the United States and Italy – the removal of the Robert E. Lee statue in Charlottesville, Virginia and the Legge Fiano, the abortive ban on Fascist propaganda proposed by Emanuele Fiano and the Partito Democratico – in order to identify a common set of challenges now confronting liberal democracies on both sides of the Atlantic. While acknowledging the longue durée of memory politics surrounding the Confederacy and Fascism respectively, the article argues that disputes over their monuments and symbols must also be situated in terms of contemporary debates over national identity, race, populism, citizenship and speech.
We propose a method for precision control of the temporal pulse shape in 808 nm emission from Er-doped fluoroindate glasses. Previously, authors have reported the model based controller design, in which the controller varies and controls the pump rate in real time through the pump power. In model-based design, the performance of the resultant controller depends on the accuracy of the mathematical model used to represent the device in the design process. In this paper a more robust control scheme using model-free approach is presented. Specifically, the controller design is independent of the mathematical model and hence any modeling error has no effect on the device performance. This robustness against modeling error is critical for control purposes in optical materials where various up-conversion parameters are unknown or hard to determine with certainty.
From 1924–1928, Gertrude Caton-Thompson and Elinor Gardner surveyed and excavated Epipalaeolithic and Neolithic sites across the Fayum north shore in Egypt, publishing a volume entitled The Desert Fayum (1934). Since then, a number of researchers have worked in the Fayum (e.g. Wendorf & Schild 1976; Hassan 1986; Wenke et al. 1988; Kozłowski & Ginter 1989), and most recently the UCLA/RUG/UOA Fayum Project. The long history of research in the area means that the Fayum is a testament to changing archaeological approaches, particularly regarding the Neolithic. Caton-Thompson and Gardner's study is recognised as one of the most progressive works on Egyptian prehistory, and their research provided the foundation for many subsequent studies in the region (e.g. Wendrich & Cappers 2005; Holdaway et al. 2010, 2016; Shirai 2010, 2013, 2015, 2016a; Emmitt 2011; Emmitt et al. 2017; Holdaway & Wendrich 2017). A recent article in Antiquity, however, uses Caton-Thompson and Gardner's preliminary interpretations of their excavations at a stratified deposit in the Fayum, Kom W, to generate a series of speculative statements concerning agricultural origins in the region (Shirai 2016b). The majority of these statements are very similar to conclusions initially made by Caton-Thompson and Gardner in the first half of the twentieth century, and new data and theory needed to reassess earlier conclusions are not considered. Recently published studies concerning the Fayum north shore and adjacent regions provide a different view of the state of research in this region and the Egyptian Neolithic in general. Here we acquaint Antiquity readers with current archaeological approaches to the Fayum north shore Neolithic, with the intent of stimulating academic debate.
There are roughly 25 very metal-poor (VMP; [Fe/H] < -2.0), highly r-process-enhanced (‘r-II’; [Eu/Fe] > + 1.0) stars currently known, discovered over the past 20+ years. These stars provide nearly pure signatures of r-process events early in the Galactic history. We are conducting a high-resolution follow-up survey of RAVE and other bright targets to identify a total of > 100 r-II stars. Our pilot runs on the du Pont 2.5-m at Las Campanas Observatory and the ARC 3.5-m at Apache Point Observatory have already identified up to fourteen new r-II stars. We are continuing our high-resolution follow-up efforts to constrain the astrophysical site(s) and nature of the r-process.
