ABSTRACTObjectivesTo evaluate the reproducibility of measurement of the fetal left modified myocardial performance index (Mod‐MPI) determined using a novel automated system.MethodsThis was a prospective study of 116 ultrasound examinations from 110 normal singleton pregnancies at 12 + 1 to 37 + 1 weeks' gestation. Two experienced operators each measured the left Mod‐MPI twice manually and twice automatically using the Auto Mod‐MPI system. Intra‐ and interoperator reproducibility were assessed using intraclass correlation coefficients (ICCs) and the manual and automated measurements obtained by the more experienced operator were compared using Bland–Altman plots and ICCs.ResultsBoth operators successfully measured the left Mod‐MPI in all cases using the Auto Mod‐MPI system. For both operators, intraoperator reproducibility was higher when performing automated measurements (ICC = 0.967 and 0.962 for Operators 1 and 2, respectively) than when performing manual measurements (ICC = 0.857 and 0.856 for Operators 1 and 2, respectively). Interoperator agreement was also better for automated than for manual measurements (ICC = 0.930 vs 0.723, respectively). There was good agreement between the automated and manual values measured by the more experienced operator.ConclusionsThe Auto Mod‐MPI system is a reliable technique for measuring fetal left Mod‐MPI and demonstrates excellent reproducibility.

Influence of adjacent crop type on occurrence of California ground squirrels on levees in the Sacramento Valley, California
Authors: McGrann Michael C. , Van Vuren Dirk H. , Ordeñana Miguel A. 
Published: November 2013

ABSTRACTIn the Sacramento Valley in California, USA, burrowing activities of California ground squirrels (Otospermophilus beecheyi) on levees pose a threat to human safety and property by potentially compromising levee integrity during a flood event. Ground squirrel occurrence on levees is influenced by habitat features on the levee itself, but occurrence also might be influenced by food availability in adjacent areas. During June through September 2012, we evaluated the association between the occurrence of ground squirrels on levees and 5 common land‐use types adjacent to levees: perennial nut crops, perennial fruit crops, annual crops, rice, and grassland. Using burrow entrances as an index of ground squirrel occurrence and abundance, we found that ground squirrel occurrence was highest on levees adjacent to perennial nut and fruit crops and lowest adjacent to rice and grassland. Additionally, the number of burrow entrances on levees increased with percent cover of perennial nut crops on adjacent land. Our findings highlight the importance of a landscape perspective in managing human–wildlife conflicts, and will assist levee managers in prioritizing those reaches most at risk from infestation by ground squirrels, for inspection during routine maintenance, or for monitoring during a flood event. Further, opportunities might arise to coordinate with local landowners to establish crops adjacent to levees that are least attractive to ground squirrels. © 2013 The Wildlife Society.
Accuracy of aging ducks in the U.S. Fish and Wildlife Service Waterfowl Parts Collection Survey

Published: November 2013

ABSTRACTThe U.S. Fish and Wildlife Service conducts an annual Waterfowl Parts Collection Survey to estimate composition of harvested waterfowl by species, sex, and age (i.e., juv or ad). The survey relies on interpretation of duck wings by a group of experienced biologists at annual meetings (hereafter, flyway wingbees). Our objectives were to estimate accuracy of age assignment at flyway wingbees and to explore how accuracy rates may influence bias of age composition estimates. We used banded mallards (Anas platyrhynchos; n = 791), wood ducks (Aix sponsa; n = 242), and blue‐winged teal (Anas discors; n = 39) harvested and donated by hunters as our source of birds used in accuracy assessments. We sent wings of donated birds to wingbees after the 2002–2003 and 2003–2004 hunting seasons and compared species, sex, and age determinations made at wingbees with our assessments based on internal and external examination of birds and corresponding banding records. Determinations of species and sex of mallards, wood ducks, and blue‐winged teal were accurate (>99%). Accuracy of aging adult mallards increased with harvest date, whereas accuracy of aging juvenile male wood ducks and juvenile blue‐winged teal decreased with harvest date. Accuracy rates were highest (96% and 95%) for adult and juvenile mallards, moderate for adult and juvenile wood ducks (92% and 92%), and lowest for adult and juvenile blue‐winged teal (84% and 82%). We used these estimates to calculate bias for all possible age compositions (0–100% proportion juv) and determined the range of age compositions estimated with acceptable levels of bias. Comparing these ranges with age compositions estimated from Parts Collection Surveys conducted from 1961 to 2008 revealed that mallard and wood duck age compositions were estimated with insignificant levels of bias in all national surveys. However, 69% of age compositions for blue‐winged teal were estimated with an unacceptable level of bias. The low preliminary accuracy rates of aging blue‐winged teal based on our limited sample suggest a more extensive accuracy assessment study may be considered for interpreting age compositions of this species.

Non-homogeneous rapid distortion theory on transversely sheared mean flows
Authors: Goldstein M. E. , Afsar M. Z. , Leib S. J. 
Published: November 2013

AbstractThis paper is concerned with the small-amplitude unsteady motion of an inviscid non-heat-conducting compressible fluid on a transversely sheared mean flow. It extends previous analyses (Goldstein,J. Fluid Mech., vol. 84, 1978b, pp. 305–329; Goldstein,J. Fluid Mech., vol. 91, 1979a, pp. 601–632), which show that the hydrodynamic component of the motion is determined by two arbitrary convected quantities in the absence of solid surfaces and hydrodynamic instabilities. These results can be used to specify appropriate upstream boundary conditions for unsteady surface interaction problems on transversely sheared mean flows in the same way that the vortical component of the Kovasznay (J. Aero. Sci., vol. 20, 1953, pp. 657–674) decomposition is used to specify these conditions for surface interaction problems on uniform mean flows. But unlike Kovasznay’s result, the arbitrary convected quantities no longer bear a simple relation to the physical variables. A major purpose of this paper is to complete the formalism developed in Goldstein’s earlier two papers by obtaining the necessary relations between these quantities and the measurable flow variables. The results are important because they enable the complete extension of non-homogeneous rapid distortion theory to transversely sheared mean flows. Another purpose of the paper is to derive a generalization of the famous Ffowcs Williams and Hall (J. Fluid Mech., vol. 40, 1970, pp. 657–670) formula for the sound produced by the interaction of turbulence with an edge, which is frequently used as a starting point for predicting sound generation by turbulence–solid surface interactions. We illustrate the utility of this result by using it to calculate the sound radiation produced by the interaction of a two-dimensional jet with the downstream edge of a flat plate.
Electrostatically controlled large-amplitude, non-axisymmetric waves in thin film flows down a cylinder
Authors: Wray A. W. , Papageorgiou D. T. , Matar O. K. 
Published: November 2013

AbstractWe examine the dynamics of a thin film flowing under gravity down the exterior of a vertically aligned inner cylinder, with a co-aligned, concentric cylinder acting as an outer electrode; the space between the outer cylinder and the film is occupied by an inviscid gas. The stability of the interface is studied when it is subjected to an electric field, applied by imposing a potential difference between the two cylinders. Leaky-dielectric theory is used in conjunction with asymptotic reduction, in the large-conductivity limit, to derive a single, two-dimensional evolution equation for the interfacial location, which accounts for gravity, capillarity, and electrostatic effects. A linear stability analysis is carried out which shows that non-axisymmetric modes become more dominant with increasing electric field strength. Our fully two-dimensional numerical solutions of the evolution equation demonstrate qualitative agreement between the trends observed in the nonlinear regime and those predicted by linear theory. These numerical solutions also show that, depending on the electric field strength and the relative proximity of the outer electrode, the interface either remains spatially uniform, or exhibits either axisymmetric or, importantly, non-axisymmetric travelling waves. The effect of wave formation on the interfacial area is investigated in connection with the use of electric fields to control thin film flows to enhance heat and mass transfer rates.

AbstractTranscritical flow of a stratified fluid past a broad localised topographic obstacle is studied analytically in the framework of the forced extended Korteweg–de Vries, or Gardner, equation. We consider both possible signs for the cubic nonlinear term in the Gardner equation corresponding to different fluid density stratification profiles. We identify the range of the input parameters: the oncoming flow speed (the Froude number) and the topographic amplitude, for which the obstacle supports a stationary localised hydraulic transition from the subcritical flow upstream to the supercritical flow downstream. Such a localised transcritical flow is resolved back into the equilibrium flow state away from the obstacle with the aid of unsteady coherent nonlinear wave structures propagating upstream and downstream. Along with the regular, cnoidal undular bores occurring in the analogous problem for the single-layer flow modelled by the forced Korteweg–de Vries equation, the transcritical internal wave flows support a diverse family of upstream and downstream wave structures, including kinks, rarefaction waves, classical undular bores, reversed and trigonometric undular bores, which we describe using the recent development of the nonlinear modulation theory for the (unforced) Gardner equation. The predictions of the developed analytic construction are confirmed by direct numerical simulations of the forced Gardner equation for a broad range of input parameters.
Intangibles, Export Intensity, and Company Performance in the French Wine Industry
Authors: Amadieu Paul , Maurel Carole , Viviani Jean-Laurent 
Published: November 2013

AbstractIntangible assets can play a strategic role in the implementation of differentiated strategies in foreign markets. The literature has addressed the impact of intangible assets on both exports and financial performance and the effects of exports on company financial performance (profit and risk). This article aims to analyze the effect of exports on the relationship between intangibles and company performance in the wine industry. Empirical studies show that intangibles have a positive but diminishing impact on exports. The effect of exports on financial performance differs depending on whether we consider corporations or cooperatives. While intangible expenses reduce company risk in both samples whatever the level of export intensity, the effects are different with profit. In corporations, intangible expenses have a positive impact on profit only when there is a high level of expenses and a high level of export intensity. (JEL Classifications: G32, L25, Q12, Q13)
IS THERE A LACUNA IN PS.-PLUTARCH (‘AETIUS’) 4.11.1–4? TWO ACCOUNTS OF CONCEPT FORMATION IN HELLENISTIC PHILOSOPHY

In Ps.-Plutarch's epitome,Doctrines of the Philosophers(Plac.),lemma4.11 bears the heading: Πῶς γίνεται ἡ αἴσθησις καὶ ἡ ἔννοια καὶ ὁ κατὰ ἐνδιάθεσιν λόγος (‘How sense perception, conception, and internal reason come to be’). The text reads:(1) Οἱ Στωϊκοί ϕασιν· ὅταν γεννηθῇ ὁ ἄνθρωπος, ἔχει τὸ ἡγεμονικὸν μέρος τῆς ψυχῆς ὥσπερ χάρτην εὔεργον εἰς ἀπογραϕήν· εἰς τοῦτο μίαν ἑκάστην τῶν ἐννοιῶν ἐναπογράϕεται.

(2) The first way of writing is through the senses. For when humans perceive something, e.g. something white, they have a memory of it when it goes away; and when many memories of the same kind have come to be, then we say that they have experience; for experience is a plurality of impressions of the same kind. (3) Of conceptions, some come about naturally and non-technically through the aforementioned ways, but others come about through our own learning and efforts. The latter are called ‘conceptions’, but the former are called ‘prolepses’ as well. (4) And reason, according to which we are called ‘rational’, is said to be completely filled out with prolepses at the age of seven years.
OF GODS, MEN AND STOUT FELLOWS: CICERO ON SALLUSTIUS'EMPEDOCLEA(Q. FR.2.10[9].3)
Authors: Cowan Robert 
Published: November 2013

Cicero's letter to his brother Quintus from February 54 is best known for containing the sole explicit contemporary reference to Lucretius’De rerum natura, but it is also notable as the source of the only extant reference of any kind to another (presumably) philosophical didactic poem, Sallustius’Empedoclea(Q. fr.2.10(9).3= SB 14):Lucretii poemata, ut scribis, ita sunt: multis luminibus ingenii, multae tamen artis. sed, cum ueneris. uirum te putabo, si Sallusti Empedoclea legeris; hominem non putabo.Lucretius’ poems are just as you write: they show many flashes of inspiration, but many of skill too. But more of that when you come. I shall think you a man, if you read Sallustius’Empedoclea; I shan't think you a human being.
CAESAR, LUCRETIUS AND THE DATES OFDE RERUM NATURAAND THECOMMENTARII
Authors: Krebs Christopher B. 
Published: November 2013

In February 54b.c. Cicero concludes a missive to his brother with a passing and – for us – tantalizing remark:Lucreti poemata ut scribis ita sunt, multis luminibus ingeni, multae tamen artis. sed cum veneris. virum te putabo si Sallusti Empedoclea legeris; hominem non putabo. Quintus had, it seems, readDe rerum natura, or at least parts thereof, just before he left Rome for an undisclosed location nearby, and he shared his enthusiasm with his brotherper codicillos. Meanwhile, he was corresponding with Julius Caesar, whose staff in Gaul he was about to join. When, a few months later, he was stationed with Caesar, he was involved in another literary affair, this time concerning his brother who wrote to him, inquiring about his autobiographicalDe temporibus suis:quo modo nam, mi frater, de nostris versibus Caesar? nam primum librum se legisse scripsit ad me ante, et prima sic ut neget se ne Graeca quidem meliora legisse; reliqua ad quendam locum ῥᾳθυμότερα (hoc enim utitur verbo). dic mihi verum: num aut res eum aut χαρακτὴρ non delectat?(Q.fr.2.15.5)
LUCRETIUS' SELF-POSITIONING IN THE HISTORY OF ROMAN EPICUREANISM
Authors: Eckerman Chris 
Published: November 2013

At Book 5.324–37, the DRN’s narrator says that the world is young, claims that the nature of the world has been understood only recently (with the advent of Epicureanism), and asserts that he is either the ‘very first’/‘most pre-eminent’ or, as I suggest here, ‘among the first’/‘among the most pre-eminent’ to turn (vertere) Greek Epicureanism into Latin. It is the last of these three claims that concerns us:denique natura haec rerum ratioque repertast 335nuper, et hanc primus cum primis ipse repertusnunc ego sum in patrias qui possim vertere voces.Commentators and translators persistently interpret the phrase primus cum primis at line 336 to mean ‘the very first’, taking cum primis as an intensifier of primus and providing primus with a temporal denotation. A comment by Reid is typical: ‘The phrase cum primis, as used by [Lucretius], has lost its literal sense, and means “particularly”, “especially”’. It is not immediately clear, however, whether one should choose the temporal (‘first’) or qualitative (‘pre-eminent’) denotation for primus or whether one should allow ambiguity and grant that some readers may interpret the adjective temporally while others may interpret it qualitatively. I suggest that the passage primus cum primis ipse repertus | nunc ego sum in patrias qui possim vertere voces means ‘I myself have now been discovered to be a pre-eminent person, among pre-eminent people, of the type who is able to turn this (i.e. the ratio mentioned in the previous line) into our native tongue’. Cum primis should be understood literally, following standard Latin grammar, as an ablative construed with cum denoting accompaniment rather than as an intensifier. While Leonard and Smith suggest that ‘the phrase cum primis … seems to have originated in the idea of accompaniment and implicit comparison’, here I show that the prepositional phrase cum primis retains its original meaning of accompaniment in Lucretius. As I shall argue, we should be sceptical of commentators who exhort us to interpret cum primis at 5.336 as an intensifier, since the phrase makes good sense, following standard Latin grammar, as an ablative of accompaniment, and Lucretius’ use of the phrase cum primis elsewhere is always qualitative, never temporal. Moreover, several scholars have used 5.336 to date early Italian Epicureans, including C. Amafinius, and the interpretation of 5.336, accordingly, affects Lucretius’ temporal position, as well as, perhaps, his intellectual engagement in relation to Italian Epicureans. There is, then, much at stake in the interpretation of 5.336, since the narrator may be found to be either honest or not (depending on how one interprets 5.336), when he positions Lucretius in relation to the translation of Epicureanism into Latin.
VENI VIDI VICIAND CAESAR'S TRIUMPH
Authors: Östenberg Ida 
Published: November 2013

Without doubt,veni vidi viciis one of the most famous quotations from Antiquity. It is well known that it was Julius Caesar who coined the renowned expression. Less frequently discussed is the fact that ‘I came, I saw, I conquered’ was announced as written text. According to Suetonius, Caesar paraded a placard displaying the wordsveni vidi viciin his triumph held over Pontus in 46b.c.(Suet.Iul. 37.2):Pontico triumpho inter pompae fercula trium verborum praetulit titulum VENI VIDI VICI non acta belli significantem sicut ceteris, sed celeriter confecti notam.In his Pontic triumph he exhibited among the biers of the procession a placard (titulus) with three words VENI VIDI VICI, not to show the deeds performed in the war, as in the others, but to mark out how fast the war had been concluded.
QUO USQUE TANDEM CANTHERIUM PATIEMUR ISTUM?(APUL.MET.3.27): LUCIUS, CATILINE AND THE ‘IMMORALITY’ OF THE HUMAN ASS
Authors: La Bua Giuseppe 
Published: November 2013

Shortly after his accidental transformation into an ass, Lucius attempts to return to his human form by grabbing some roses decorating a statue of the patron goddess of the quadrupeds, Epona. But hisservulusfeels outraged at the sacrilegious act. Jumping to his feet in a temper and acting as a faithful defender of the sacred place, he addresses his former human owner as a new ‘Catiline’ (Apul.Met.3.27):Quod me pessima scilicet sorte conantem servulus meus, cui semper equi cura mandata fuerat, repente conspiciens indignatus exurgit et: ‘quo usque tandem’ inquit ‘cantherium patiemur istum paulo ante cibariis iumentorum, nunc etiam simulacris deorum infestum? Quin iam ego istum sacrilegum debilem claudumque reddam.’My attempt was frustrated by what seemed to be the worst of luck: my own dear servant, who always had the task of looking after my horse, suddenly saw what was going on, and jumped up in a rage. ‘For how long’, he cried, ‘are we to endure this clapped-out beast? A minute ago his target was the animals' rations, and now he is attacking even the statues of deities! See if I don't maim and lame this sacrilegious brute!’A self-evident instance of parody, the servant's words ironically reformulate one of the most familiar texts of Republican oratory, the famous opening of Cicero's first invective against Catiline, delivered before the assembled senate in the Temple of Jupiter Stator on 8 November 63b.c.: the substitution of a low and familiar word such ascantheriumforCatilinamunderpins the comic undertone of the entire passage, imbued with further reminiscences of Cicero. Scholars debate whether the servant's verbal attack against Lucius is a parodic adaptation of Cicero's opening invective or rather a spoof on Catiline's paradoxical reading of Cicero's phrase in Sallust (Sall.Cat. 20.9). It is safer to assume a case of double imitation, not unusual in Apuleius' work.
DEPRECIATION IN VITRUVIUS
Authors: Rihll T.E. 
Published: November 2013

Vitruvius has something interesting to say at De architectura 2.8.8:
Non enim quae sunt e molli caemento subtili facie venustatis, non eae possunt esse in vetustate non ruinosae. itaque cum arbitrio communium parietum sumuntur, non aestimant eos quanti facti fuerint, sed cum ex tabulis inveniunt eorum locationes, pretia praeteritorum annorum singulorum deducunt octogesimas et ita – ex reliqua summa parte reddi pro his parietibus – sententiam pronuntiant eos non posse plus quam annos LXXX durare.Those structures made of soft rubble, for all their subtle attractiveness, are not the ones that will resist ruin as time passes. And thus when assessors are appointed to evaluate party walls, they never assess soft rubble walls according to their initial cost, but rather, when they look at the price recorded in the original contracts, they deduct 1/80th of that sum for each subsequent year, and the remaining amount is fixed as the current value of the walls. They have rendered judgement, in effect, that such walls cannot last more than 80 years.By contrast, mud-brick walls were not depreciated at all if they were standing when assessed (Vitr. 2.8.9). The calculation performed for concrete walls demonstrates clear understanding of what we call ‘depreciation’ or ‘amortization’ in ancient Roman thought. It appears to have been overlooked to date.
