description: We study complex time series (spike trains) of online user communication while spreading messages about the discovery of the Higgs boson in Twitter. We focus on online social interactions among users such as retweet, mention, and reply, and construct different types of active (performing an action) and passive (receiving an action) spike trains for each user. The spike trains are analyzed by means of local variation, to quantify the temporal behavior of active and passive users, as a function of their activity and popularity. We show that the active spike trains are bursty, independently of their activation frequency. For passive spike trains, in contrast, the local variation of popular users presents uncorrelated (Poisson random) dynamics. We further characterize the correlations of the local variation in different interactions. We obtain high values of correlation, and thus consistent temporal behavior, between retweets and mentions, but only for popular users, indicating that creating online attention suggests an alignment in the dynamics of the two interactions.

Introduction

description: Unlike what happens in literature or cinema, in theatre (both in its textual and performative dimensions) a precise distinction between a long form (generically standardized and corresponding to a novel or a feature film) and a short one (roughly comparable to a short story or a short film) has never been codified. At least in the modern Western world, drama has been traditionally identified with a work (usually divided into acts) with a running time long enough to entertain an audience for one night. Since they could not ‘fill the bill’ for one night, short dramas have been widely ignored and underestimated by critics and drama theorists alike, even though they have successfully stood next to longer pieces since the origins of theatre itself in the form of interludes, farces performed at the end of plays, levers du rideau, and so on. In fact, it was only from the nineteenth century onwards that one-act plays were officially acknowledged in Naturalist and, later on, Symbolist theatre and short forms – at least if compared to traditional dramaturgy – found their place within the ‘serious’ drama production. This phenomenon grew during the twentieth century when not only did short forms become shorter but often voiced parodical, critical or even the destructuring of bourgeois drama and were especially exploited first by avant-garde movements and, later on, by the mid-century theatrical experimentalism of the Absurd and beyond. From then onwards, the production of short (and shorter) dramas has profitably spread, as proven by the establishment of seasons, festivals, and awards expressly devoted to this kind of theatre. The second issue of Skenè. Journal of Theatre and Drama Studies will be dedicated to short drama in the twentieth and early twenty-first century and particularly aims at analysing its main aesthetic prerogatives and specific potentialities with regard to dramatic writing and performative realization as well as to its impact on contemporary theatre receptive and organizing practices. The issue’s contributions will therefore investigate not only the theatrical movements and the single dramatists, whose production has been largely and sometimes even exclusively dedicated to short drama, but also the new models of organization and the dynamics of reception and social interaction that short drama has dealt with or has contributed to create.

Spatial Fourier analysis of video photobleaching measurements. Principles and optimization
Creators: name: Jacobson, K. A.
name: Tsay, T. T.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1991

description: The major use of the fluorescence recovery after photobleaching (FRAP) technique is to measure the translational motion of the molecular components in various condensed media. In a conventional laser spot photobleaching experiment, a photomultiplier is used to measure the total brightness levels of the bleached region in the sample, so no spatial information can be directly obtained. In video-FRAP, a series of images after photobleaching is acquired, allowing the spatial character of the recovery to be determined; this permits direct detection of both anisotropic diffusion and flow. To utilize all of the available image data to determine the transport coefficients, a two-dimensional spatial Fourier transform analysis of the images after photobleaching was employed. The change in the transform between two time points reflects the action of diffusion during the interim. An important advantage of this method, which involves taking the ratio of image transforms at different time points, is that it does not require a specific initial condition to be created by laser photobleaching. The ability of the analysis to extract transport coefficients from computer-simulated diffusional recovery is assessed in the presence of increasing amounts of noise. Experimental data analysis from the diffusion of proteins in viscous solutions and from the diffusion of protein receptors on cell surfaces demonstrate the feasibility of the Fourier analysis to obtain transport coefficients from the video FRAP measurement.
A computer scientist's reconstruction of quantum theory

description: The rather unintuitive nature of quantum theory has led numerous people to develop sets of (physically motivated) principles that can be used to derive quantum mechanics from the ground up, in order to better understand where the structure of quantum systems comes from. From a computer scientist's perspective we would like to study quantum theory in a way that allows interesting transformations and compositions of systems and that also includes infinite-dimensional datatypes. Here we present such a compositional reconstruction of quantum theory that includes infinite-dimensional systems. This reconstruction is noteworthy for three reasons: it is only one of a few that includes no restrictions on the dimension of a system; it allows for both classical, quantum, and mixed systems; and it makes no a priori reference to the structure of the real (or complex) numbers. This last point is possible because we frame our results in the language of category theory, specifically the categorical framework of effectus theory.

Hemispherical Anomaly from Asymmetric Initial States

description: We investigate if the hemispherical asymmetry in the CMB is produced from "asymmetric" excited initial condition. We show that in the limit where the deviations from the Bunch-Davies vacuum is large and the scale of new physics is maximally separated from the inflationary Hubble parameter, the primordial power spectrum is modulated only by position dependent dipole and quadrupole terms. Requiring the dipole contribution in the power spectrum to account for the observed power asymmetry, $A=0.07\pm0.022$, we show that the amount of quadrupole terms is roughly equal to $A^2$. The {\it mean} local bispectrum, which gets enhanced for the excited initial state, is within the $1σ$ bound of Planck 2015 results for a large field model, $f_{\rm NL}\simeq 4.17$, but is reachable by future CMB experiments. The amplitude of the local non-gaussianity modulates around this mean value, depending on the angle that the correlated patches on the 2d CMB surface make with the preferred direction. The amount of variation minimizes for the configuration in which the short and long wavelengths modes are around the preferred pole and $|\vec k_3|\approx |\vec k_{l\approx10}|\ll |\vec k_1|\approx |\vec k_2|\approx |\vec k_{l\approx2500}|$ with $f_{\rm NL}^{\rm min}\approx 3.64 $. The maximum occurs when these modes are at the antipode of the preferred pole, $f_{\rm NL}^{\rm max}\approx 4.81$ . The difference of non-gaussianity between these two configurations is as large as $\simeq 1.17$ which can be used to distinguish this scenario from other scenarios that try to explain the observed hemispherical asymmetry.

Correlated Short-Timescale Hard-Soft X-ray Variability of the Blazars Mrk 421 and 1ES 1959+650 using $\textit{AstroSat}$

description: We study simultaneous soft ($0.7 - 7$ keV) and hard ($7 - 20$ keV) X-ray light curves at a total of eight epochs during $2016 - 2019$ of two TeV blazars Mrk 421 and 1ES 1959+650 observed by the SXT and LAXPC instruments onboard AstroSat. The light curves are $45 - 450$ ks long and may be sampled with time bins as short as $600 - 800$ sec with high signal to noise ratio. The blazars show a harder when brighter trend at all epochs. Discrete cross-correlation functions indicate that the hard and soft X-ray variability are strongly correlated. The time lag is consistent with zero in some epochs, and indicates hard or soft lag of a few hours in the rest. In the leptonic model of blazar emission, soft lag may be due to slower radiative cooling of lower energy electrons while hard lag may be caused by gradual acceleration of the high energy electrons emitting at the hard X-ray band. Assuming the above scenario and the value of the Doppler factor ($δ$) to be $10 - 20$, the hard and soft lags may be used to estimate the magnetic field to be $\sim 0.1$ Gauss and the acceleration parameter to be $\sim 10^4$ in the emission region. Due to the availability of the high time resolution ($\sim$ minutes to hours) light curves from AstroSat, the value of the illusive acceleration parameter could be estimated, which provides a stringent constraint on the theories of particle acceleration in blazar jets.

Comedy, Catharsis, and the Emotions: From Aristotle to Proclus
Creators: name: Cohn, Matt
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2016

description: This paper takes a fresh look at ancient theories about the catharsis afforded by comedy. I adopt the model of Aristotelian catharsis proposed by Richard Janko and Stephen Halliwell and argue that Aristotle thought that comedy should elicit, and thus effect catharsis of, not only pleasurable emotions, such as the emotion associated with laughter, but also certain painful ones as well. In particular, Aristotle hints in the Poetics that certain comic plots elicit the painful emotion indignation as part of the process of eliciting pleasurable emotions that I call ‘justified schadenfreude’ and ‘justified gratulation’. These emotions are intertwined with fear and pity in Aristotle’s philosophy of the emotions, and thus the catharsis of such a comedy complements the catharsis of tragedy. I next turn to later theories in the Tractatus Coislinianus, Iamblichus, and Proclus. These tend to distort or diverge from Aristotle’s theory, but all four are in agreement in one important respect: comedy produces real emotions, and those emotions are in need of catharsis.

Nietzsche, Tragedy, and the Theory of Catharsis
Creators: name: Porter, James I.
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2016

description: Nietzsche’s view of catharsis has attracted some but not a great deal of attention. Part of the reason is that he rarely makes use of the term itself, whether in his Birth of Tragedy or elsewhere, and when he does he is rather dismissive, seemingly rejecting out of hand the Aristotelian-inspired theory of tragic catharsis in its ancient or modern (notably, classicizing) forms. Catharsis would appear to be an unrewarding area for understanding Nietzsche. Nevertheless, it is undeniable that The Birth of Tragedy appears to foreground Nietzsche’s rejection of tragic catharsis in its classical form, and the book is surely very much about catharsis in this sense. As it happens, a closer look at both this work and a handful of later texts on tragedy in Nietzsche’s writings suggests that catharsis theory is everywhere on his mind even where the term is not being mentioned, not least of all in The Birth of Tragedy, where it is fully operative in the form of pity or co-suffering (Mitleid[en]), identificatory fear and horror (Furcht, Schrecken), and redemptive discharge (Erlösung, Entladung). Nor is his view as clear-cut as his emphatic rejection of Aristotelian catharsis might appear to indicate. His view of catharsis is neither simple nor entirely uniform across his corpus. Nietzsche’s understanding of catharsis proves to be much closer to the view he appears to reject, and much closer to classicism’s reading of tragedy than one might suppose.

Evanescent interference patterns for fluorescence microscopy

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1992

description: The increasing experimental use of total internal reflection/fluorescence photobleaching recovery has motivated a theoretical study of the spatial intensity profiles generated by two interfering evanescent waves. The interference patterns generated by evanescent waves differ considerably from those generated by plane waves in a homogenous medium because evanescent waves are not transverse and because the evanescent propagation number depends on the incidence angle of the totally internally reflected light. The periodicity and contrast of the evanescent interference patterns under various conditions are calculated; these parameters depend on the intensities, polarizations, and incidence angles of the two incident beams, as well as the refractive indices of the two media that form the planar interface where total internal reflection occurs. The derived intensity profiles are used to develop expressions for the shapes of fluorescence photobleaching recovery curves when evanescent interference patterns are used for fluorescence excitation and bleaching. The calculations also suggest that colliding beam experiments may confirm theoretically predicted evanescent field polarizations.

Miraculous Organ: Shakespeare and 'Catharsis'

Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2016

description: Noting that Aristotle’s Poetics was not published in England until 1623, this article begins by surveying the traces of cathartic thinking in early modern cultural theory, paying special attention to Sir Philip Sidney’s Defence of Poesy as the era’s most significant expression of that theory. Showing the Defence is not a sufficient cause of Shakespearean cathartic thinking, it traces extant ideas of purgation in England’s wider literary, Christian and medical traditions, arguing these provided Shakespeare with the purgative basis of his theatre. The article gives special prominence to Thomas Kyd’s The Spanish Tragedy, arguing its theatrical influence was a significant transmitter of purgative ideas to Shakespeare, the drama of the age, and Hamlet.

Assessing the Impact of Metacognitive Post-Reflection Exercises on Problem-Solving Skillfulness

description: We studied the impact of metacognitive reflections on recently completed work as a way to improve the retention of newly-learned problem-solving techniques. Students video-recorded themselves talking through problems immediately after finishing them, completed ongoing problem-solving strategy maps or problem-sorting exercises, and filled out detailed exam wrappers. We assessed students' problem-solving skillfulness using a combination of validated instruments and final exam questions scored using a rubric that targets problem-solving best practices. We found a small but significant difference between the rubric score distributions for the control and treatment groups. However, a multiple ordered logistic regression using treatment and Force Concept Inventory (FCI) pre-test score as predictors showed that this difference is better explained by the latter. The surprising impact of conceptual preparation on problem-solving skill suggests two things: the importance of remediation for students with insufficient conceptual understanding and the need to consider problem-solving interventions in the context of students' conceptual knowledge base.

Theatrical Catharsis and Its Therapeutic Effect. Catharsis in Vienna at the Turn of the Century
Creators: name: Schönle, Daniela M.
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2016

description: Around 1900, catharsis became “one of the most frequently discussed topics amongst scholars and an equally popular conversation topic at the Viennese salons” (Ellenberger 1970: 2.655). The so-called ‘Viennese discourse on catharsis’ emerged as a reaction to Jacob Bernays’s commentary on Aristotle’s Poetics in which he interpreted the effects of tragedy as a medical procedure. Another important premise for the diffusion and popularization of the topic in the Danube metropolis was the activism of Theodor Gomperz, who not only spread the position of Jacob Bernays amongst philologists, but also succeeded in stirring the enthusiasm of people working outside the Classics departments. In 1893, for instance, the Viennese physicians Sigmund Freud and Josef Breuer presented a therapy that was supposed to cure hysteria. Influenced by Gomperz, and following Bernays’s assumptions, Freud and Breuer named their treatment “cathartic method”. Searching for novel means of expression and insight, and being particularly interested in the description of affective phenomena, the artists of the ‘Wiener Moderne’ also adopted catharsis as a theme and discussed Bernays’s interpretation and Breuer’s and Freud’s explanation of it in their writings. This article elucidates the foundations of the ‘Viennese discourse on catharsis’ and shows how contemporary playwrights reacted to the debate, using the works of Arthur Schnitzler and Hermann Bahr as examples.

Theophrastus on Catharsis and the Need for Release from the Evils Due to Emotions
Creators: name: Matelli, Elisabetta
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2016

description: Theophrastus had a systematic approach to the traditional problem of “catharsis” and treated the question referring to different fields of knowledge. He proved a keen and unprejudiced observer and collector of the largest possible number of experiences that may describe different kinds of catharsis. At a speculative level, he proceeded in continuity with and yet going beyond his teacher’s opinions. Important building blocks in the construction of his cathartic theory were the development of the Aristotelian method through the criterion of the “more and the less”, which became the guiding principle he applied to physiological enquiries into humors and warmth. This led to a consequent focus on the physiological motions connected with the ones of the soul (both explained in terms of a dynamic relationship between different degrees of “tension” and “relaxation”, two key terms) and with the interpretation of ethical issues in relation to the different degrees of “tension” or “relaxation” of the motions of the soul linked to the emotions in so far as this dynamics produces both vices or virtues. The locution apolysis tôn kakôn (“release from evils”) seemingly substituted the term “catharsis” in the ethical contexts in which Theophrastus elaborated his original take on the theme. The cathartic effect of the physiological and psychological “release from evils” operated through a precise use of the human voice (valid both in music and in the performing arts) involves both the performer and the audience: from an ethical point of view, apolysis tôn kakôn (i.e. catharsis) represents the unique end or purpose of his qualitative conception of music. In his view, religious piety does not consist in animal sacrifice or in traditional rites, but rather in an ethical “catharsis from evils” (katharsis ton kakon); therefore, this religious issue might be considered as the starting point and the conclusion of Theophrastus’s philosophical theory of catharsis, a theory in which the whole range of his science is involved.

description: In the presence of transition magnetic moments between active and sterile neutrinos, the search for a Primakoff upscattering process at coherent elastic neutrino-nucleus scattering (CE$ν$NS) experiments can provide stringent constraints on the neutrino magnetic moment. We show that a radiative upscattering process with an emitted photon in the final state can induce a novel coincidence signal at CE$ν$NS experiments that can also probe neutrino transition magnetic moments beyond existing limits. Furthermore, the differential distributions for such a radiative mode can also potentially be sensitive to the Dirac vs. Majorana nature of the sterile state mediating the process. This can provide valuable insights into the nature and mass generation mechanism of the light active neutrinos.

description: A 1-meter-long trapezoidal Triple-GEM detector with wide readout strips was tested in hadron beams at the Fermilab Test Beam Facility in October 2013. The readout strips have a special zigzag geometry and run along the radial direction with an azimuthal pitch of 1.37 mrad to measure the azimuthal phi-coordinate of incident particles. The zigzag geometry of the readout reduces the required number of electronic channels by a factor of three compared to conventional straight readout strips while preserving good angular resolution. The average crosstalk between zigzag strips is measured to be an acceptable 5.5%. The detection efficiency of the detector is (98.4+-0.2)%. When the non-linearity of the zigzag-strip response is corrected with track information, the angular resolution is measured to be (193+-3) urad, which corresponds to 14% of the angular strip pitch. Multiple Coulomb scattering effects are fully taken into account in the data analysis with the help of a stand-alone Geant4 simulation that estimates interpolated track errors.

The models are constructed from the anisotropic distribution function of Gunn & Griffin (1979), combined with the modified Poisson equation defining this gravitation theory and take into account the external field effect. We have used these models, and their Newtonian analogues, to fit the projected density and the velocity dispersion profiles of a sample of 18 Galactic globular clusters, using the most updated datasets of radial velocities and Gaia proper motions. We have thus obtained, for each cluster, estimates of the dynamical mass-to-light ratio ($M/L$) for each theory of gravity. The selected clusters have accurate proper motions and a well sampled mass function down to the very low mass regime. This allows us to constrain the degree of anisotropy and to provide, from comparison with stellar evolution isochrones, a dynamics-independent estimate of the minimum mass-to-light ratio $(M/L)_{min}$. Comparing the best-fitting dynamical $M/L$ with $(M/L)_{min}$, we find that for none of the analyzed clusters the two gravity theories are significantly incompatible with the observational data, although for one of them (NGC 5024) the dynamical $M/L$ predicted by QUMOND lies at $2.8σ$ below $(M/L)_{min}$. Though the proposed approach suffers from some limitations (in particular the lack of a treatment of mass segregation), the obtained results suggest that the kinematics of globular clusters in a relatively weak external field can be a powerful tool to prove alternative theories of gravitation.

description: Background: Modern code review is expected to facilitate knowledge sharing: All relevant information, the collective expertise, and meta-information around the code change and its context become evident, transparent, and explicit in the corresponding code review discussion. The discussion participants can leverage this information in the following code reviews; the information diffuses through the communication network that emerges from code review. Traditional time-aggregated graphs fall short in rendering information diffusion as those models ignore the temporal order of the information exchange: Information can only be passed on if it is available in the first place. Aim: This manuscript presents a novel model based on time-varying hypergraphs for rendering information diffusion that overcomes the inherent limitations of traditional, time-aggregated graph-based models. Method: In an in-silico experiment, we simulate an information diffusion within the internal code review at Microsoft and show the empirical impact of time on a key characteristic of information diffusion: the number of reachable participants. Results: Time-aggregation significantly overestimates the paths of information diffusion available in communication networks and, thus, is neither precise nor accurate for modelling and measuring the spread of information within communication networks that emerge from code review. Conclusion: Our model overcomes the inherent limitations of traditional, static or time-aggregated, graph-based communication models and sheds the first light on information diffusion through code review. We believe that our model can serve as a foundation for understanding, measuring, managing, and improving knowledge sharing in code review in particular and information diffusion in software engineering in general.

Calcium-dependent inactivation of L-type calcium channels in planar lipid bilayers

description: Intracellular Ca2+ can inhibit the activity of voltage-gated Ca channels by modulating the rate of channel inactivation. Ca(2+)-dependent inactivation of these channels may be a common negative feedback process important for regulating Ca2+ entry under physiological and pathological conditions. This article demonstrates that the inactivation of cardiac L-type Ca channels, reconstituted into planar lipid bilayers and studied in the presence of a dihydropyridine agonist, is sensitive to Ca2+. The rates and extents of inactivation, determined from ensemble averages of unitary Ba2+ currents, decreased when the calcium concentration facing the intracellular surface of the channel ([Ca2+]i) was lowered from approximately 10 microM to 20 nM by the addition of Ca2+ chelators. The rates and extents of Ba2+ current inactivation could also be increased by subsequent addition of Ca2+ raising the [Ca2+]i to 15 microM, thus demonstrating that the Ca2+ dependence of inactivation could be reversibly regulated by changes in [Ca2+]i. In addition, reconstituted Ca channels inactivated more quickly when the inward current was carried by Ca2+ than when it was carried by Ba2+, suggesting that local increases in [Ca2+]i could activate Ca(2+)-dependent inactivation. These data support models in which Ca2+ binds to the channel itself or to closely associated regulatory proteins to control the rate of channel inactivation, and are inconsistent with purely enzymatic models for channel inactivation.

description: Exploiting the optical sectioning capabilities of laser scanning confocal microscopy and using parameter-specific fluorescent probes, we determined the distribution of pH, free Ca2+, electrical potential, and volume inside cultured adult rabbit cardiac myocytes during ATP depletion and reductive stress with cyanide and 2-deoxyglucose ("chemical hypoxia"). During normoxic incubations, myocytes exhibited a cytosolic pH of 7.1 and a mitochondrial pH of 8.0 (delta pH = 0.9 units). Sarcolemmal membrane potential (delta psi) was -80 mV, and mitochondrial delta psi was as high as -100 mV, yielding a mitochondrial protonmotive force (delta p) of -155 mV (delta P = delta psi - 60 delta pH).

Theory for measuring bivalent surface binding kinetics using total internal reflection with fluorescence photobleaching recovery

description: Total internal reflection with fluorescence photobleaching recovery (TIR-FPR) is a method for experimentally examining coupled diffusion and reaction kinetics at surfaces. In a previous work (Thompson et al. 1981. Biophys. J. 33:435-454), a theoretical basis for interpreting TIR-FPR data was described for monovalent ligands that undergo a reversible reaction with monovalent surface sites in a single step. Here, the theory for TIR-FPR has been extended to two different surface binding mechanisms that involve sequential, bivalent surface attachment. Methods for obtaining the intrinsic surface association and dissociation kinetic rates from measured fluorescence photobleaching recovery curves are described. The new theory should be applicable to the association of bivalent protein ligands such as antibodies with supported planar model membranes.
Catharsis, Music, and the Mysteries in Aristotle

description: Of the many meanings of katharsis available to Aristotle, two have predominated in scholarly attempts to say what the word means in the Poetics when “the katharsis of pity and fear produced by pity and fear” is defined as the aim of tragedy. The past thirty years have seen a concerted effort among scholars of the Poetics to overturn Jacob Bernays’ appeal to Aristotle’s use of katharsis in his Politics (1342a10-11) with its medical meaning of ‘purgation’ as the basis of his theory that tragedy provides a harmless ‘outlet’ for emotions; against this, Plato’s notion of intellectual ‘purification’ as a kind of katharsis has been invoked to argue that the workings of the tragic art were fundamentally cognitive and resulted in the ethical ‘clarification’ of the audience. The present essay proposes that Aristotle’s theory of tragedy was deeply informed by another meaning of the word in his day: the ecstatic release provided by certain mystery cults. After underlining Aristotle’s familiarity with such rituals, it draws on Walter Burkert’s Ancient Mystery Cults to bring out suggestive commonalities between mystery initiations and theatre. The ‘telestic’ ‘initiations’ (τέλη) aimed not at the afterlife but at alleviating fears and anxieties of initiates; both their secret nocturnal ceremonies and public choral processions were dramatic and highly theatrical, with an essential role played by ecstasy-inducing ‘sacred tunes’. In order to discern the relevance of telestic katharsis to the Poetics it is necessary not to focus solely on the definition of tragedy in chapter 6 but to appreciate the anthropological approach to the poetic arts in chapter 4. This context supplies, if not a fully worked out model of tragic katharsis, a broad-based explanation of how human beings might respond to imitations of terrible things with pleasure and profit.

Profit, Pleasure, and Purgation - Catharsis in Aristotle, Paolo Beni and Italian Late Renaissance Poetics

description: The Cinquecento has seen an unprecedented flourishing of literary theory. While many other issues are disputed, nearly all critics agree that poetry should entertain and delight, but also produce some kind of moral benefit. When Aristotle’s Poetics enters the debate, interpreters seek and find in his work a confirmation of their view. In his celebrated notorious catharsis clause, Aristotle seems to hint at the moral effect that should be obtained by tragedy. Since he does not explain the term in the transmitted Poetics text, interpreters fill in what they regard as its missing parts. The way in which they do this also reveals their own preconceptions of what should be classed as moral profit. This paper describes the range of the different meanings which are attached to Aristotelian catharsis in the secondo Cinquecento. After having explored the relationship between pleasure and profit in Aristotle, it deals with Renaissance theorists, using Paolo Beni’s commentary on the Poetics as a starting point. Beni’s commentary is the last substantial contribution to the Cinquecento debate, and his critical review of the different readings of catharsis that had been developed in the preceding decades provides us with a useful overview. Employing Beni’s criticism as a guideline, the article further characterizes the various Renaissance approaches to catharsis and traces their origins.
