The development and validation of a stereotypic-beliefs inventory
Creators: name: Van Ommeren, Mark H.
Publisher: name: University of British Columbia
Year: 2009

description: This paper describes the development and validation of the Stereotypic-Beliefs Inventory (SBI), an instrument that measures individual differences in the extent to which Canadians hold stereotypic-beliefs and non-stereotypic beliefs about ethnic groups. A stereotypic-belief is defined as the belief that members of cultural/ethnic outgroups differ systematically in specific personality characteristics from members of cultural/ethnic ingroups. Non-stereotypic-beliefs, polar opposite to stereotypic-beliefs, are beliefs that members of cultural/ethnic outgroups do not systematically differ in specific personality characteristics from members of cultural/ethnic ingroups. In Phase 1 of the study 21 graduate students generated 50 stereotypic-belief and 50 non-stereotypic-belief items. In Phase 2, 119 undergraduate students rated the items for social desirability; in Phase 3 a new sample of 107 undergraduate students rated the extent to which they agreed with the items. Item analytic procedures reduced the item pool to a 24-item scale (SBI) that was balanced for social desirability and acquiescence. Factor analysis yielded a 2-factor solution; Factor 1: disagreement with non-stereotypic-beliefs and Factor 2: agreement with stereotypic-beliefs. In the last phase, Phase 4, 50 undergraduate students completed the SBI, Paulhus' (1988) Balanced Inventory for Desirable Responding, Rosenberg's (1965) Self-Esteem Scale, Altemeyer's (1981) Authoritarianism Scale, McConahay's (1986) Modern Racism Scale (MRS), and the Canadian Modern Racism Scale (CMRS), a modified version of the MRS. Except for the non-significant correlation between the SBI and the Self-Esteem Scale, predicted relations between the administered scales were observed, indicating moderate construct validity for the SBI. The SBI's reliability was assessed (Cronbach alpha = .93; 2-week test-retest reliability r(38) = .83). Also, the new CMRS (Cronbach alpha = .79) correlated in meaningful ways with the conceptually related scales, supporting high construct validity for the CMRS. Strengths, weaknesses, and implications for further research are presented and discussed.

description: We present an analysis of TESS and Kepler light curves for 4,947 K+K wide binaries from the SUPERWIDE Catalog. We use these systems to examine the usefulness of the “Lobster” diagram, a plot which allows for the identification of over-luminous components in wide binaries using Gaia data alone. These over-luminous components are believed to be unresolved binaries, making the wide binaries a triple (or even quadruple) system. To confirm this, we search through the high cadence light curves from TESS, Kepler and K2 and the data products produced from the MIT Quick Lookup Pipeline for signals from eclipses and from rotational modulation in spotted fast-rotating stars. We identify 64 eclipsing systems and 115 systems showing signs of fast rotation. We highlight the systems containing eclipsing binaries, fast rotators (P<5 days) and rotators (P>5 days) on the “Lobster” diagram. Eclipsing binaries are overwhelmingly found to be in areas that show a component is over-luminous. Fast rotators are also more likely to be found in these areas while stars showing rotation with periods > 5 days are more likely to be found where true wide binaries are believed to be located.

description: This paper addresses the role of the adverb in Dutch direct object scrambling constructions. We report four experiments in which we investigate whether the structural position and the scope sensitivity of the adverb affect acceptability judgments of scrambling constructions and native speakers' tendency to scramble definite objects. We conclude that the type of adverb plays a key role in Dutch word ordering preferences.

description: We investigate the overdamped Langevin motion for particles in a potential well that is asymptotically flat. When the potential well is deep compared to temperature, physical observables like the mean square displacement are essentially time-independent over a long time interval, the stagnation epoch. However the standard Boltzmann-Gibbs (BG) distribution is non-normalizable, given that the usual partition function is divergent. For this regime, we have previously shown that a regularization of BG statistics allows the prediction of the values of dynamical and thermodynamical observables in the non-normalizable quasi-equilibrium state. In this work, based on the eigenfunction expansion of the time-dependent solution of the associated Fokker-Planck equation with free boundary conditions, we obtain an approximate time-independent solution of the BG form, valid for times which are long, but still short compared to the exponentially large escape time. The escaped particles follow a general free-particle statistics, where the solution is a an error function, shifted due to the initial struggle to overcome the potential well. With the eigenfunction solution of the Fokker-Planck equation in hand, we show the validity of the regularized BG statistics and how it perfectly describes the time-independent regime though the quasi-stationary state is non-normalizable.

description: Filling out the dearth of detections between directly imaged and radial velocity planets will test theories of planet formation across the full range of semi-major axes, connecting formation of close to wide separation gas giants, and also substellar companions. Direct detection of close-in companions is notoriously difficult: coronagraphs and point spread function (PSF) subtraction techniques are significantly limited in separation and contrast. Non- redundant aperture masking interferometry (NRM or AMI) can be used to detect companions well inside the PSF of a diffraction limited image, though the technique is severely flux-limited since the mask discards ~95% of the gathered light. Kernel-phase analysis applies similar interferometric techniques to an unobscured diffraction limited image, simulating the full telescope aperture as an interferometer composed of a grid of subapertures. I have developed a new faint companion detection pipeline which analyzes kernel-phases utilizing Bayesian model comparison. I break open the black box of interferometry by demonstrating the use of this pipeline on archival HST/NICMOS images of nearby brown dwarfs. I refine astrometry of previously known companions and search for new companions, in order to constrain formation models at au scales. I also present contrast curves to demonstrate the strength of this technique at separations inaccessible to classical imaging techniques. Using this method, it is possible to detect companions down to flux ratios of $\sim10^2$—reaching the planetary-mass regime for young targets—at half the classical $\lambda/D$ diffraction limit while using a fraction of the telescope time as NRM. Since JWST will be able to perform NRM and unobscured imaging, further development and characterization of kernel-phase analysis will allow efficient use of competitive JWST time.

description: Exoplanet detection with precise radial velocity (RV) observations is currently limited by spurious RV signals introduced by the host star in the form of stellar activity (i.e. faculae, starspots). Here we show that a cross-disciplinary approach blending solar physics, exoplanet astronomy, and computer science can help us further our understanding of stellar activity signals. Using machine learning techniques such as linear regression and neural networks, we demonstrate that we can significantly reduce the activity signals (primarily starspots/faculae) from real center-of-mass RV shifts. Previous efforts have focused on carefully filtering out activity signals in time using Gaussian process regression (e.g. Haywood et al. 2014). Instead, we separate activity signals from true center-of-mass RV shifts using only changes to the average shape of spectral lines, and no information about when the observations were collected. We have trained our machine learning models on both simulated data (generated with the SOAP 2.0 software; Dumusque et al. 2014) and observations of the Sun from the HARPS-N Solar Telescope (Dumusque et al. 2015; Phillips et al 2016; Collier Cameron et al. 2019). We find that these techniques can successfully predict and remove stellar activity from approximately 700 observations taken nearly daily over three years with the HARPS-N Solar Telescope, reducing the RV scatter from 1.47 m s-1 to 0.78 m s-1 (a 47% or factor of ~ 1.9 improvement). For the simulated data, these techniques can predict the stellar activity signal nearly exactly, reducing the RV scatter from 82.0 cm s-1 to 3.1 cm s-1 which suggests that we may be able to achieve more precise velocities when applied to data from newer stabilized spectrographs like ESPRESSO. In the future, these or similar techniques could remove activity signals from observations of stars outside our solar system and eventually help detect habitable-zone Earth-mass exoplanets around Sun-like stars.

description: Folded linear molecular chains are ubiquitous in biology. Folding is mediated by intra-chain interactions that "glue" two or more regions of a chain. The resulting fold topology is widely believed to be a determinant of biomolecular properties and function. Recently, knot theory has been extended to describe the topology of folded linear chains such as proteins and nucleic acids. To classify and distinguish chain topologies, algebraic structure of quandles has been adapted and applied. However, the approach is limited as apparently distinct topologies may end up having the same number of colorings. Here, we enhance the resolving power of the quandle coloring approach by introducing Boltzmann weights. We demonstrate that the enhanced coloring invariants can distinguish fold topologies with an improved resolution.

description: We investigate whether prototypicality or prominence of semantic roles can account for role-related effects in sentence interpretation. We present two acceptability-rating experiments testing three different constructions: active, personal passive and DO-clefts involving the same type of transitive verbs that differ with respect to the agentive role features they select. Our results reveal that there is no cross-constructional advantage for prototypical roles (e.g., agents), hence disconfirming a central tenet of role prototypicality. Rather, acceptability clines depend on the construction under investigation, thereby highlighting different role features. This finding is in line with one core assumption of the prominence account stating that role features are flexibly highlighted depending on the discourse function of the respective construction.

description: A huge number of articles support the notion that perinatal stress associates with birth outcome (preterm birth, low birth weight). Τhis study aims to associate perinatal stress with fetal development in first and second trimester. Methods: We found 48 pregnants 21 to 40 years old in Hippokration General Hospital of Thessaloniki who completed a questionnaire, which measures stress, twice, in first and second trimester. Informations on fetal development were obtained from nuchal translucency ultrasounds and level 2 ultrasounds and we collected the vital signs (blood pressure and heart rate) and the results of blood tests of first and second trimester. Results: Perinatal stress of second trimester has positive effect on biparietal diameter, on head circumference, on abdominal circumference, on femur length and on weight of embryo in second trimester. Also perinatal stress of first trimester has positive effect on head circumference and on femur length of embryo in second trimester. Finally maternal blood pressure and maternal heart rate have affect on embryo, negative and positive respectively. Conclusion: Perinatal stress in first and second trimester has positive effect on fetal development in second trimester.

description: Two acceptability judgment experiments are presented which investigate extraposition of PPs out of NP in German. The experiments are concerned with the weight of the extraposed constituent and the question of how to define weight, as well as with the definiteness status of the NP out of which the PP is extraposed. In both experiments, sentences with a PP in adjacent position to its NP were rated significantly higher than sentences with extraposed PPs. The number of phrasal nodes does not have an influence on the acceptability of extraposition, while the length of the constituent seems to play a role. The findings also suggest that there is a "soft'' definiteness constraint on the extraposition of PP out of NP in German.

Mira Variables

description: One of the fundamental topics in astrophysics is how stars enrich their environments as they reach the end of their lives. This enrichment is vital for new star and planet formation, but our understanding of molecule and dust production in circumstellar environments is still rudimentary. Mira variables are highly evolved cool stars with regular pulsations that loft enriched material into their surroundings, making them perfect laboratories for studying molecules and dust in stellar environments. I will present time-dependent analysis of mid-infrared spectra of 14 oxygen-rich (M-type) Mira variables taken with the Spitzer Infrared Spectrograph (IRS) in the high-resolution mode. Each star has multiple spectra obtained over a one-year period (from 2008-09) which allows us to analyze how pulsations affect the stellar atmospheres. We have identified several CO2 Q-branch bandheads in the M-type spectra. These lines exhibit unique, fluctuating behavior possibly tied to the pulsational phase of the star. We built a custom molecular file of ro-vibrational data to model the CO2 bandheads with the radiative transfer code RADEX. The results from the models indicate that CO2 is highly extended in Mira atmospheres. The models also show the kinetic temperature of the CO2 layers is cool enough for dust condensation to occur within a few stellar radii; this is observational evidence of “refrigeration zones” that have been theorized as part of the dust condensation process. The analysis from the CO2 features also indicates that Miras with longer periods (over 300 days) have different atmospheric behavior than those with shorter periods.

description: Neutron energy-dependent angular distributions were observed for individual $γ$-rays from the 0.74 eV p-wave resonance of $^{139}$La+$n$ to several lower excited states of $^{140}$La. The $γ$-ray signals were analyzed in a two dimensional histogram of the $γ$-ray energy, measured with distributed germanium detectors, and neutron energy, determined with the time-of-flight of pulsed neutrons, to identify the neutron energy dependence of the angular distribution for each individual $γ$-rays. The angular distribution was also found for a photopeak accompanied with a faint p-wave resonance component in the neutron energy spectrum. Our results can be interpreted as interference between s- and p-wave amplitudes which may be used to study discrete symmetries of fundamental interactions.

description: We analyze leptogenesis in a supersymmetric triplet seesaw scenario that explains the observed neutrino masses, adopting a phenomenological approach where the decay branching ratios of the triplets and the amount of CP--violation in its different decay channels are assumed as free parameters. We find that the solutions of the relevant Boltzmann equations lead to a rich phenomenology, in particular much more complex compared to the non--supersymmetric case, mainly due to the presence of an additional Higgs doublet. Several unexpected and counter--intuitive behaviors emerge from our analysis: the amount of CP violation in one of the decay channels can prove to be be irrelevant to the final lepton asymmetry, leading to successful leptogenesis even in scenarios with a vanishing CP violation in the leptonic sector; gauge annihilations can be the dominant effect in the determination of the evolution of the triplet density up to very high values of its mass, leading anyway to a sizeable final lepton asymmetry, which is also a growing function of the wash--out parameter K=Gamma_d/H, defined as usual as the ratio between the triplet decay amplitude Gamma_d and the Hubble constant H; on the other hand, cancellations in the Boltzmann equations may lead to a vanishing lepton asymmetry if in one of the decay channels both the branching ratio and the amount of CP violation are suppressed, but not vanishing. The present analysis suggests that in the supersymmetric triplet see-saw model successful leptogenesis can be attained in a wide range of scenarios, provided that an asymmetry in the decaying triplets can act as a lepton--number reservoir.

description: The aim of the present thesis was to study the quality of life of adults with mental retardation and their perceptions, as well as the perceptions of professionals who work in their intimate environment. We examined the terminology of mental retardation and quality of life as they are formulated in the general theoretical frame. Mental retardation’s characteristics were noted, in general. Also, social characteristics of adults with mental retardation and the stigma they come along, which modulates their relations and those social characteristics, were documented as well. Furthermore, there were introduced the features and domains of quality of life, their correlation between them and the characteristics of adults with mental retardation, but also the way they influence and modulate their quality of life. The special relation of self-determination and quality of life, not only as a domain of her but also as a basic component. Ways of quality’s of life assessment were noted, too. Finally, there were extensively presented, the results that came from the study and the way they were correlated with the initial hypothesis and the general theoretical background of this research field.

description: L’importanza del miele come sostanza culturalmente ed economicamente rilevante nel mondo antico non è stata ancora del tutto indagata. Il miele e le api sono nondimeno presenze assidue e trasversali ai generi e alle tipologie di fonti antiche greche e romane, ed è pertanto da esse che una ricerca sull’argomento deve partire. I manufatti, le tecniche e i concetti descritti dagli antichi devono però essere relazionati con cautela al materiale archeologico rinvenuto, per fare ciò pare indispensabile un approccio che tenga conto delle nozioni biologiche, etologiche e zootecniche di base. Attraverso quest’ottica sono state ricapitolate le evidenze materiali provenienti dal bacino del Mediterraneo e concernenti gli strumenti e le strutture relative all’apicoltura, dalle arnie agli apiari, per
il lungo arco cronologico che va dall’età del bronzo alla tarda antichità. Ciò è possibile per la tematica apicola grazie alla conservatività delle tecniche, strettamente legate ai severi dettami della natura fino alla rivoluzione ottocentesca delle arnie razionali a telai mobili del reverendo Langstroth. Sono inoltre analizzati gli utilizzi più frequenti del miele per come descritti dalle fonti letterarie nonché le implicazioni di api e miele nella ritualità e nel simbolismo della morte, del genere e della regalità, sebbene i risultati siano scarsi data la povertà dei riscontri archeologici e la limitata attenzione di cui questo argomento ha fin ora goduto.

description: Evidentiality represents the abstract grammatical system encoding the source of information (Aikhenvald, 2004), and one hypothesis is that evidential systems' development in languages could be explained through the action of cognitive biases on language learning (Fedzechkina et al., 2012). Consequently, this article tests the learnability of different two-category (Aikhenvald, 2004) evidential systems, in a semi-artificial language learning experiment with Bulgarian speakers, and hypothesizes to reflect the typological pattern of those systems' distribution in the world languages. The alternative hypothesis predicts that the learnability of the evidential systems would depend on the languages that the participants speak and would be influenced by a morphosyntactic transfer from participants' native language - the grammatically evidential “Non-firsthand versus ‘everything else’“ (Aikhenvald, 2004) Bulgarian. Despite the fact that the mixed-model analyses performed on accuracy and response time did not display any significant effect or interaction (p > 0.1), the small trends showed by the results possibly reflect a salient cognitive and semantic distinction between direct and indirect evidential information that is easier for acquisition, compared to marking which violates this categorisation.
Acculturation and eating attitudes and behaviours in female Chinese and Caucasian university students: a correlational and comparative study
Creators: name: Hyland, Colleen Anne
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to examine the role of sociocultural factors in the occurrence of pathological eating attitudes and behaviours by determining the relationship between acculturation to Canada, as a Western culture , and eating attitudes and behaviours in a nonclinical sample of female Chinese and Caucasian university students. In addition , as an exploratory goal any possible relationship between acculuturative stress and eating attitudes and behaviours was also explored. One hundred female Caucasian and 131 female Chinese undergraduate students were recruited from the University of British Columbia. Each subject was asked to complete a Demographic Questionnaire as well as the 26 item Eating Attitudes Test (EAT; Garner, Olmsted, Bohr, & Garfinkel, 1982). Additionally , the Chinese subjects were asked to complete the Suinn-Lew Asian Self-Identity Acculturation Scale (SL-ASIA; Suinn, Rickard-Figueroa, Lew, & Vigil, 1987) and the 24 item SAFE Acculturative Stress Scale (SAFE; Mean, Padilla, & Maldonado, 1987).

description: This paper is a study of the history of the transplant of mathematical tools using negative feedback for macroeconomic stabilization policy from 1948 to 1975 and the subsequent break of the use of control for stabilization policy which occurred from 1975 to 1993. New-classical macroeconomists selected a subset of the tools of control that favored their support of rules against discretionary stabilization policy. The Lucas critique and Kydland and Prescott's time-inconsistency were over-statements that led to the "dark ages" of the prevalence of the stabilization-policy-ineffectiveness idea. These over-statements were later revised following the success of the Taylor rule.

LE COMPETENZE FINANZIARIE DEI CONSOLI: ANALISI DI UN EPISODIO RELATIVO A SCIPIONE AFRICANO
Creators: name: Bellomo, Michele
Publisher: name: ACME
Year: 2014

description: Questo articolo prende in analisi le relazioni tra senato e consoli riguardo alla gestione delle finanze a Roma. Secondo Polibio, sebbene il senato detenesse un forte controllo sulle normali spese statali, i consoli godevano di una particolare autonomia per i fondi ad essi destinati. Una visione che sarebbe confermata da un episodio avente come protagonista Scipione Africano, il quale, in una seduta del senato collocata dagli studiosi al tempo del suo secondo consolato, avrebbe minacciato i questori di aprire personalmente i forzieri dell’Erario. In questo articolo si cercherà di dimostrare che l’episodio, se attribuibile a uno dei due consolati di Scipione, trova una sua più esatta collocazione al tempo del primo consolato (205 a. C.), e che esso non può essere preso come esempio dell’autonomia dei consoli in campo finanziario. Al contrario, esso sembra costituire un’ulteriore riprova della predominanza del Senato in questo campo.

description: We present a group theoretical analysis of the superconducting state of the Bechgaard salts, e.g., (TMTSF)_2PF_6 or (TMTSF)_2ClO_6. We show that there are eight symmetry distinct superconducting states. Of these only the (fully gapped, even frequency, p-wave, triplet) 'polar state' is consistent with the full range of the experiments on the Bechgaard salts. The gap of the polar state is d(k) (psi_uk,0,0), where psi_uk may be any odd parity function that is translationally invariant.

8.4b_Sommerfeld: Airborne wind energy trajectory optimization using realistic wind speed profiles
Creators: name: , Sommerfeld
Publisher: name: Zenodo
Year: 2019
Subjects: Airborne Wind Energy Systems, AWES, trajectory optimization, wind energy, wind profile cluster

description: The goal of this study is to estimate an ensemble of annual energy production and dynamic tether loads of Airborne Wind Energy Systems (AWES) based on representative operational wind speed profiles. AWES aim to operate at altitudes above conventional wind turbines where wind speeds are generally higher and assumed to be more predictable. However, these devices will still operate within the atmospheric boundary layer, the part of the atmosphere which is directly influenced by the contact with earths surface. Therefore, a wide range of atmospheric stability conditions develop as a result of synoptic and diurnal weather conditions which can lead to significant variations in wind speed profiles. Wind speed profiles from mesoscale Weather Research and Forecasting (WRF) simulations form the basis of this analysis,since continuous high resolution wind measurements are scarce. The WRF simulations have been nudged where possible using data from a LiDAR measurement campaign. Wind speed profiles will be input into the open source Airborne Wind Energy optimal control toolbox (AWEbox) to determine optimal flight paths over the entire set of wind profiles. Results over the whole ensemble are then statistically analyzed and clustered to examine the impacts of boundary profiles on AWE performance and compared to results based on reanalysis data with a resolution of three to six hours and even more simplified mean profiles typically used for control/system optimization studies.

Year: 2021
Subjects: subject: Systems and Control (eess.SY)

description: In this paper, a distributed formation flight control topology for Leader-Follower formation structure is presented. Such topology depends in the first place on online generation of the trajectories that should be followed by the agents in the formation. The trajectory of each agent is planned during execution depending on its neighbors and considering that the desired reference trajectory is only given to the leader. Simulation using MATLAB/SIMULINK is done on a formation of quadrotor UAVs to illustrate the proposed method. The topology shows very good results in achieving the formation and following the reference trajectory.

description: Evolutionary games are studied where the teaching activity of players can evolve in time. Initially all players following either the cooperative or defecting strategy are distributed on a square lattice. The rate of strategy adoption is determined by the payoff difference and a teaching activity characterizing the donor's capability to enforce its strategy on the opponent. Each successful strategy adoption process is accompanied with an increase in the donor's teaching activity. By applying an optimum value of the increment this simple mechanism spontaneously creates relevant inhomogeneities in the teaching activities that support the maintenance of cooperation for both the prisoner's dilemma and the snowdrift game.

description: Η παρούσα εργασία διερευνά τη γλωσσική χρήση, τη γλωσσική επιλογή και τη γλωσσική διατήρηση ή μετακίνηση των Ελλήνων μεταναστών δεύτερης γενιάς στη Γερμανία. Η έρευνα εξετάζει, επίσης, τις στάσεις των υποκειμένων απέναντι στην εθνοτική γλώσσα και την εθνοτική ταυτότητα. Η έρευνα πραγματοποιήθηκε σε 30 συμμετέχοντες μέσω ερωτηματολογίων και συνεντεύξεων. Από τα δεδομένα προκύπτει ότι η εθνοτική γλώσσα παραμένει ο κύριος κώδικας επικοινωνίας στο σπίτι. Ωστόσο, παρατηρείται και μία αυξημένη χρήση της γερμανικής γλώσσας, ιδιαίτερα όταν συνομιλητές των υποκειμένων είναι τα παιδιά τους. Διαπιστώθηκε, επίσης, ότι η ελληνική μεταναστευτική κοινότητα δεύτερης γενιάς στη Γερμανία παραμένει στενά συνδεδεμένη με την ελληνική γλώσσα και ταυτότητα και ότι υπάρχει μία ισχυρή θετική στάση για την ανάγκη διατήρησης της γλώσσας στην κοινότητα.
description: This study explores the language use, the language choice and the language maintenance/shift among second generation immigrants in Germany. It also investigates the attitudes of second generation immigrants in Germany towards ethnic language and ethnic identity. The data are collected from 30 participants through questionnaires and interviews. Findings from this study demonstrate that Greek language remains the main instrument of communication in the home domain. However, some German is also used, especially by the children. It is also shown that the Greek-German community expresses positive attitudes to language maintenance and is strongly attached to the ethnic language and to the ethnic identity.
IL LIBRO D’ORO DI ARISTOMACHE: UNA NOTIZIA ANTIQUARIA IN PLUTARCO (MOR. 675 B) E UN FRAMMENTO DI EPOS CORINTIO (EUM. FR. 8 BERNABÉ)
Creators: name: Capel Badino, Roberto
Publisher: name: ACME

description: Discutendo un problema cronologico in merito all’inclusione di gare poetiche nel contesto dei festival panellenici, Plutarco (mor. 675 b) riferisce – sull’autorità di Polemone, scrittore antiquario (fr. 27 Preller) – informazioni circa un libro d’oro offerto come ex voto nel tesoro dei Sicionii a Delfi dalla sconosciuta figura di Aristomache, vincitrice all’Istmo.
Lo studio discute alcuni problemi riguardo al testo di Plutarco – pubblicato con un nuovo apparato critico, la natura dell’ex voto e l’identità di Aristomache. Poiché non c’è notizia di agoni poetici a Corinto prima della fine del IV sec. a.C., con maggiore coerenza rispetto al ragionamento di Plutarco, Aristomache può essere considerata una figura leggendaria assimilabile a una Sibilla. Il frammento di Polemone può essere confrontato con Eum. fr. 8 Bernabé (Favor. Corinth. 13, p. 305.8 Barigazzi), un frammento di un’opera epica, dove una Sibilla, parlando in prima persona, fornisce una tradizione corintia circa l’origine delle Istmie.
