description: Genus VIII.— LESTES, Leach.
 Wings narrow, thin and membranaceous, composed of numerous small areolets, the greater portion of which (especially towards the apex) are pentagonal, the fourth longitudinal nervure angulated; stigma oblong, rather large: abdomen slender, nearly linear, being a little dilated at the apex, which in the males is furnished with semicircular appendages, of the female with simple ones; w ings half expanded (as in Smerinthus) during repose. Mask of the larvae with a double projection on the upper edge of the mentum.
 Prom Agrion the species of this genus are distinguished with facility by the areolets of the wings being more numerous, and by the greater portion of them towards the apex, especially on the margins, being either pentagonal or polygonal, rarely quadrangular, the fourth longitudinal nervure being much angulated in numerous zigzags; the stigma is oblong, and the males are distinguished by having the apex of the abdomen armed with curved forceps; yet, regardless of these obvious distinctions, these insects, as well as those of the preceding genus, were long considered as constituting one species only, and are thus considered in the latest works of the celebrated Latreille, although the discrepancies of the two genera were pointed out by Leach in 1810!!

description: We present morphological and statistical results of a study of neutral hydrogen (HI) in a complete sample of nearby, non-cluster radio galaxies. We detect large-scale HI emission in the early-type host galaxies of 25% of our sample sources. The large-scale HI is mainly distributed in disk- and ring-like structures with sizes up to 190 kpc and masses up to 2 x 10^10 M_solar. All radio galaxies with M_HI >= 10^9 M_solar have a compact radio source. When we compare our sample of radio-loud early-type galaxies with samples of radio-quiet early-type galaxies there appears to be no significant difference in HI properties (mass, morphology and detection rate). This suggests that that the radio-loud phase could be just a short phase that occurs at some point during the life-time of many, or even all, early-type galaxies.

description: Σκοπός της διπλωματικής εργασίας ήταν η μελέτη της σχέσης μεταξύ γιατρού και ασθενή σε όλες τις ιστορικές περιόδους της ζωής του και το ηθικό υπόβαθρο που έτυχε να διέπει τα δύο αυτά πρόσωπα σε αυτή τη συναναστροφή. Ιδιαίτερη αναφορά έγινε στη ρήξη της πολύχρονης αυτής σχέσης που διαπιστώνεται τα τελευταία χρόνια καθώς ο ρόλος του ασθενή αποκτά άλλη διάσταση, ενώ ο γιατρός φαίνεται να αποστασιοποιείται από τον ασθενή του. Τέλος γίνεται αναφορά στην προσπάθεια αποκατάστασης της σχέσης γιατρού και ασθενή καθώς αποτελεί βασικό συστατικό της θεραπευτικής διαδικασίας. Αν ο ασθενής δεν εμπιστεύεται τον θεράποντα ιατρό δεν θα ακολουθήσει και την προτεινόμενη θεραπεία κι επομένως δεν θα καταφέρει να αναρρώσει πλήρως. Για το λόγο αυτό δίνονται προτάσεις υπέρβασης των προβλημάτων επικοινωνίας, ώστε να νιώσει και πάλι σιγουριά και ασφάλεια ο ασθενής. Επιπλέον, προβάλλονται σύγχρονα παραδείγματα επιστημόνων που παραμέρισαν το προσωπικό τους όφελος χάριν των ασθενών τους και πραγμάτωσαν τον αληθινό ρόλο του γιατρού που σκύβει πάνω στον πόνο του ασθενή.
description: The aim of the present thesis was to study the relationship between the physician and the patient in all historic period of his life and the moral background was regulating the two persons in this interaction. Particular reference was made to break the long-lasting relationship that is found in recent years as the role of patient enters another dimension while the doctor seems to be distancing himself from his patient. Finally, a reference to the recovery effort of the doctor and patient relationship as a key component of the healing process. If the patient does not trust the doctor would not follow the recommended treatment and therefore will be unable to recover fully. For this reason suggestions are given to overcome communication problems and therefore to once again feel the patient safe and secure. In addition examples of modern scientists come up which set aside their personal interests for the sake of their patients and realize the true role of the doctor who pays attention to the suffering of the patient.

description: We explore upper limits for the largest avalanches or catastrophes in nonlinear energy dissipation systems governed by self-organized criticality (SOC). We generalize the idealized "straight" power low size distribution and Pareto distribution functions in order to accomodate for incomplete sampling, limited instrumental sensitivity, finite system-size effects, "Black-Swan" and "Dragon-King" extreme events. Our findings are: (i) Solar flares show no finite system-size limits up to L < 200 Mm, but solar flare durations reveal an upper flare duration limit of < 6 hrs; (ii) Stellar flares observed with KEPLER exhibit inertial ranges of $E \approx 10^{34}-10^{37}$ erg, finite system-size ranges at $E \approx 10^{37}-10^{38}$ erg, and extreme events at $E =(1-5) \times 10^{38}$ erg; (iii) The maximum flare energy of different spectral-type stars (M, K, G, F, A, Giants) reveal a positive correlation with the stellar radius, which indicates a finite system-size limit imposed by the stellar surface area. Fitting our finite system-size models to terrestrial data sets (Earth quakes, wildfires, city sizes, blackouts, terrorism, words, surnames, web-links) yields evidence (in half of the cases) for finite system-size limits and extreme events, which can be modeled with dual power law size distributions.

description: This study addresses the problem of convolutional kernel learning in univariate, multivariate, and multidimensional time series data, which is crucial for interpreting temporal patterns in time series and supporting downstream machine learning tasks. First, we propose formulating convolutional kernel learning for univariate time series as a sparse regression problem with a non-negative constraint, leveraging the properties of circular convolution and circulant matrices. Second, to generalize this approach to multivariate and multidimensional time series data, we use tensor computations, reformulating the convolutional kernel learning problem in the form of tensors. This is further converted into a standard sparse regression problem through vectorization and tensor unfolding operations. In the proposed methodology, the optimization problem is addressed using the existing non-negative subspace pursuit method, enabling the convolutional kernel to capture temporal correlations and patterns. To evaluate the proposed model, we apply it to several real-world time series datasets. On the multidimensional rideshare and taxi trip data from New York City and Chicago, the convolutional kernels reveal interpretable local correlations and cyclical patterns, such as weekly seasonality. In the context of multidimensional fluid flow data, both local and nonlocal correlations captured by the convolutional kernels can reinforce tensor factorization, leading to performance improvements in fluid flow reconstruction tasks. Thus, this study lays an insightful foundation for automatically learning convolutional kernels from time series data, with an emphasis on interpretability through sparsity and non-negativity constraints.

description: The shape of clouds has proven to be essential for classifying them. Our analysis of images from fair weather cumulus clouds reveals that, besides by turbulence they are driven by self-organized criticality (SOC). Our observations yield exponents that support the fact the clouds, when projected to two dimensions (2D), exhibit conformal symmetry compatible with $c=-2$ conformal field theory (CFT), in contrast to 2D turbulence which has $c=0$ CFT. By using a combination of the Navier-Stokes equation, diffusion equations and a coupled map lattice (CML) we successfully simulated cloud formation, and obtained the same exponents.

A 43, 5418 (1991)], for the derivation of analytical forms of the radial distribution function of a fluid of hard spheres are compared. While they share similar starting philosophy, the first one involves the determination of eleven parameters while the second is a simple extension of the solution of the Percus-Yevick equation. It is found that the {second} approach has a better global accuracy and the further asset of counting already with a successful generalization to mixtures of hard spheres and other related systems.

description: We study the clustering properties of K-selected galaxies at 22.3 distant red galaxies (DRGs) have r_0 ~ 11 h^-1 Mpc. Contrary to findings for optically-selected galaxies, K-selected galaxies that are faint in the R-band cluster more strongly than brighter galaxies. These results suggest that a color-density relation was in place at z>2. Our results indicate that K-bright blue galaxies and K-bright red galaxies are fundamentally different, as they have different clustering properties. Using a simple model of one galaxy per halo, we infer halo masses ~ 5 x 10^12 M_sun for K<21 galaxies and ~ 2 x 10^13 M_sun for DRGs. A comparison of the observed space density of DRGs to the density of their host halos suggests large halo occupation numbers; however, this result is at odds with the lack of a strong small-scale excess in the angular correlation function. We find that the z=0 descendants of the galaxies considered here reside primarily in groups and clusters. [abridged]

description: Estimating3D hand poses from RGB images is essentialto a wide range of potential applications, but is challengingowing to substantial ambiguity in the inference of depth in-formation from RGB images. State-of-the-art estimators ad-dress this problem by regularizing3D hand pose estimationmodels during training to enforce the consistency betweenthe predicted3D poses and the ground-truth depth maps.However, these estimators rely on both RGB images and thepaired depth maps during training. In this study, we proposea conditional generative adversarial network (GAN) model,called Depth-image Guided GAN (DGGAN), to generate re-alistic depth maps conditioned on the input RGB image, anduse the synthesized depth maps to regularize the3D handpose estimation model, therefore eliminating the need forground-truth depth maps. Experimental results on multiplebenchmark datasets show that the synthesized depth mapsproduced by DGGAN are quite effective in regularizing thepose estimation model, yielding new state-of-the-art resultsin estimation accuracy, notably reducing the mean3D end-point errors (EPE) by4.7%,16.5%, and6.8%on the RHD,STB and MHP datasets, respectively.
Consumers of good taste : Marketing modernity in Northern Mexico, 1890-1910
Creators: name: Bunker, Steven B.
Publisher: name: University of British Columbia
Year: 2009

description: Mexican historians, emphasizing capitalist production as the defining feature of nineteenth- and early twentieth century Mexican society, have largely overlooked the other question of capitalism, that of consumption. This emphasis has impeded a recognition of the cultural and social impact of a budding consumer society in Mexican cities prior to the Revolution of 1910. By the time of the 1910 Revolution, a culture of consumption had become synonymous with the public culture of the northern Mexican cities of Monterrey and Chihuahua. This consumer culture and an accompanying service economy arose where capitalist production and urban growth created mass societies of wage-earners reliant upon the market to satisfy their basic needs and increasing desires. It became a means by which enlightened Mexicans conveyed their vision of a modernizing Mexico, integrating and disseminating the messages of consumption with the principles of economic progress, nationalism, moral reform, and civic pride. By and large, this culture of consumption spoke to the sensibilities and moral values of Mexico's urban middle classes, yet it also included the artisan working classes who claimed social respectability for themselves by trying to emulate the consumption patterns of their social superiors. The effects of modern consumption also transformed gender roles and spheres of influence; new territories of public space became open to middle class women as consumption became identified as a feminine trait. Mass-circulation newspapers, department stores, commercialized entertainments, brand-name goods, and the "science of advertising" became the most visible symbols of this new culture. Not only did this culture of consumption inform the daily discourse and social relations of Mexicans, but it also transformed the urban landscape in which they worked, strolled, and found entertainment. As part of a modernizing effort by urban reformers to clean up city centers and remove vice to the fringes, shopping and entertainment districts shared public space and new urban transportation and communication networks with business establishments, civic buildings, and public monuments. Both the consumption and production sides of capitalism characterized the rapidly growing and transforming urban milieu in which increasing numbers of Mexicans lived.

description: Long-running measurements of the solar radio flux density at 810 MHz were processed. Based on the least-squares method and using modified periodograms and an iterative technique of fitting and subtracting sinusoids in the time domain, frequency, amplitude, and phase characteristics of any analyzed time series were obtained. Solar cycles 20, 21, and 22 and shorter segments around solar minima and maxima were examined separately. Also, dynamic studies with 405, 810, and 1620 day windows were undertaken. The harmonic representations obtained for all these time series indicate large differences among solar cycles and their segments. We show that the solar radio flux at 810 MHz violates the Gnevyshev-Ohl rule for the pair of cycles 22-23. Analyzing the period 1957-2004, the following spectral periods longer than 1350 days were detected: 10.6, 8.0, 28.0, 5.3, 55.0, 3.9, 6.0, 4.4, and 14.6 yr. For spectral periods between 270 and 1350 days the 11 yr cycle is not recognized. We think that these harmonics form ``impulses of activity'' or a quasi-biennial cycle defined in the Benevolenskaya model of the ``double magnetic cycle.'' The value of about 0.09 is proposed for the interaction parameter (between the low- and high-frequency components) of this model. We confirm the intermittent behavior of the periodicity near 155 days. Correlation coefficients between the radio emission at 810 MHz and sunspot numbers, as well as the radio emission at 2800 MHz calculated for 540 day intervals, depend on the solar cycle phase.

description: We present numerical analysis of the lateral movement of spherical capsule in the steady and pulsatile channel flow of a Newtonian fluid, for a wide range of oscillatory frequency. Each capsule membrane satisfying strain-hardening characteristic is simulated for different Reynolds numbers Re and capillary numbers Ca. Our numerical results showed that capsules with high Ca exhibit axial focusing at finite Re similarly to the inertialess case. We observe that the speed of the axial focusing can be substantially accelerated by making the driving pressure gradient oscillating in time. We also confirm the existence of an optimal frequency which maximises the speed of axial focusing, that remains the same found in the absence of inertia. For relatively low Ca, on the other hand, the capsule exhibits off-centre focusing, resulting in various equilibrium radial positions depending on Re. Our numerical results further clarifies the existence of a specific Re for which the effect of the flow pulsation to the equilibrium radial position is maximum. The roles of channel size on the lateral movements of the capsule are also addressed. Throughout our analyses, we have quantified the radial position of the capsule in a tube based on an empirical expression. Given that the speed of inertial focusing can be controlled by the oscillatory frequency, the results obtained here can be utilised for label-free cell alignment/sorting/separation techniques, e.g., for circulating tumor cells in cancer patients or precious hematopoietic cells such as colony-forming cells.
Economically viable CO2 electroreduction embedded within ethylene oxide manufacturing

description: Electrochemical conversion of CO2 (CO2R) into fuels and chemicals can both reduce CO2 emissions and allow for clean manufacturing in the scenario of significant expansion of renewable power generation. However, large-scale process deployment is currently limited by unfavourable process economics resulting from significant up- and down-stream costs for obtaining pure CO2, separation of reaction products and increased logistical effort. We have discovered a method for economically viable recycling of waste CO2 that addresses these challenges. Our approach is based on integration of a CO2R unit into an existing manufacturing process: ethylene oxide (EO) production, which emits CO2 as a by-product. The standard EO process separates waste CO2 from gas stream, hence the substrate for electroreduction is available at an EO plant at no additional cost. CO2 can be converted into an ethylene-rich stream and recycled on-site back to the EO reactor, which uses ethylene as a raw material, and also the anode product (oxygen) can be simultaneously valorized for the EO production reaction. If powered by a renewable electricity source, the process will significantly (ca. 80%) reduce the CO2 emissions of an EO manufacturing plant. A sensitivity analysis shows that the recycling approach can be economically viable in the short term and that its payback time could be as low as 1-2 years in the regions with higher carbon taxes and/or with access to low-cost electricity sources.

description: The local variation in inter-atomic distances, or local lattice strain often influences significantly material properties of nanoparticles. Strain measurement with ~1% precision is provided by recent atomic-resolution electron microscopy. However, the precision has been limited by noises in the experimental data. Here, we have applied one of the data-driven analyses, Gaussian process regression to predict true form of strain. The precision has been improved to be sub-percent of 0.2 % and more for detection of local strain. Rod-shaped nanoparticles have been revealed to contain characteristic lattice expansion ~+0.6 % around the subsurface cap tip area. The experimental results are reproduced by molecular dynamics simulations of the corresponding shaped atomic models. The strain peculiar to nanorods are explained in terms of curvature-dependent non-uniform surface stress due to shape anisotropy. The present results bring a hint to nanoscale engineering to optimize the strain in nanoparticles by shape control.

description: Για τη μελέτη πολύπλοκων συστημάτων που παρατηρούνται με πολυδιάστατες χρονοσειρές προτείνεται η δημιουργία δικτύων συσχέτισης με κόμβους τις χρονοσειρές και συνδέσεις τις συσχετίσεις μεταξύ τους. Ως μέτρο συσχέτισης θεωρούμε τη διασυσχέτιση και τη μερική διασυσχέτιση για μηδενική και μη-μηδενική υστέρηση, όπου η μη-μηδενική υστέρηση παραπέμπει σε εκτίμηση αιτιότητας και κατευθυνόμενες συνδέσεις δικτύου. Εξετάζουμε αν η στατιστική σημαντικότητα της συσχέτισης υποδεικνύει σωστά την επιλογή των συνδέσεων και για αυτό χρησιμοποιούμε παραμετρικό έλεγχο και έλεγχο τυχαιοποίησης, συμπεριλαμβάνοντας επίσης και τη διόρθωση λόγω πολλαπλών ελέγχων με χρήση του λανθασμένου ποσοστού ανακαλύψεων (false discovery rate). Δημιουργήσαμε δίκτυα συσχέτισης με σταθμισμένες συνδέσεις από τις τιμές των εκτιμητών συσχέτισης, καθώς και με απλές συνδέσεις όπως διαμορφώνονται από τον έλεγχο σημαντικότητας και συγκρίναμε τους δύο τύπους δικτύων με βάση κάποια στατιστικά μέτρα δικτύων (κατανομή βαθμού, συντελεστής σύμπλεξης και μήκος μονοπατιού). Οι προσομοιώσεις σε γνωστές πολυ-μεταβλητές στοχαστικές διαδικασίες έδειξαν πως η στατιστική σημαντικότητα δεν αποδίδει σωστά τη δομή του δικτύου, προσθέτοντας συνδέσεις που δεν αντιστοιχούν σε ουσιαστική συσχέτιση ή αιτιότητα. Τέλος, έγινε εφαρμογή των δικτύων συσχέτισης και αιτιότητας στην παγκόσμια χρηματιστηριακή αγορά.
description: A novel way to study complex systems observed by multivariate time-series is by means of correlation networks, where the time-series form the nodes and their correlation form the connections. For the correlation, we consider the cross-correlation and the partial cross-correlation, where for non-zero lag the measures estimate causal relationships and imply directed network connections. We investigate whether parametric and randomization tests for the correlation significance identify correctly the true connections. We consider also the correction for multiple testing using the false discovery rate. We formed correlation networks with weighted connections defined directly by the correlation estimates, as well as zero-one connections determined by the significance tests, and compared the two network types in terms of standard network measures (degree distribution, cluster coefficient and shortest path). Simulations on some known multivariate stochastic processes showed that statistical significance doesn’t ascribe correctly the network structure, adding connections that do not correspond to substantial correlation or causality. Finally, the significance tests and the correlation and causality networks were applied to indices of the global stock market.

description: We measured the magneto-optical response of (La$_{0.4}$Pr$_{0.6}$)$_{1.2}$Sr$_{1.8}$Mn$_2$O$_7$ in order to investigate the microscopic aspects of the magnetic field driven spin-glass insulator to ferromagnetic metal transition. Application of a magnetic field recovers the ferromagnetic state with an overall redshift of the electronic structure, growth of the bound carrier localization associated with ferromagnetic domains, development of a pseudogap, and softening of the Mn-O stretching and bending modes that indicate a structural change. We discuss field- and temperature-induced trends within the framework of the Tomioka-Tokura global electronic phase diagram picture and suggest that controlled disorder near a phase boundary can be used to tune the magnetodielectric response. Remnants of the spin-glass insulator to ferromagnetic metallic transition can also drive 300 K color changes in (La$_{0.4}$Pr$_{0.6}$)$_{1.2}$Sr$_{1.8}$Mn$_2$O$_7$.

This paper presents the design, implementation, and preliminary studies of a novel system utilizing face detection and optic flow algorithms to associate facial movements with sound synthesis in a topographically specific fashion. We report on our experience with various gesture-to-sound mappings and applications, and describe our preliminary experiments at musical performance using the system.

description: The inversion of electromagnetic induction data to a conductivity profile is an ill-posed problem. Regularization improves the stability of the inversion and, based on Occam's razor principle, a smoothing constraint is typically used. However, the conductivity profiles are not always expected to be smooth. Here, we develop a new inversion scheme in which we transform the model to the wavelet space and impose a sparsity constraint. This sparsity constrained inversion scheme will minimize an objective function with a least-squares data misfit and a sparsity measure of the model in the wavelet domain. A model in the wavelet domain has both temporal as spatial resolution, and penalizing small-scale coefficients effectively reduces the complexity of the model. Depending on the expected conductivity profile, an optimal wavelet basis function can be chosen. The scheme is thus adaptive. Finally, we apply this new scheme on a frequency domain electromagnetic sounding (FDEM) dataset, but the scheme could equally apply to any other 1D geophysical method.
Momentum distribution dynamics of a Tonks-Girardeau gas: Bragg reflections of a quantum many-body wavepacket

description: The dynamics of the momentum distribution and the reduced single-particle density matrix (RSPDM) of a Tonks-Girardeau (TG) gas is studied in the context of Bragg-reflections of a many-body wavepacket. We find strong suppression of a Bragg-reflection peak for a dense TG wavepacket; our observation illustrates dependence of the momentum distribution on the interactions/wavefunction symmetry. The momentum distribution is calculated with a fast algorithm based on a formula expressing the RSPDM via a dynamically evolving single-particle basis.
Investigating alpha rhythm generation in a full-density visual thalamocortical model

description: Background: The alpha rhythm is a brain oscillation with a frequency around 10 Hz that is predominantly associated with spontaneous ongoing activity and manifests in the occipitoparietal regions of various mammalian species during states of eyes-closed rest. While several hypotheses suggest thalamic and cortical circuits as the primary sources, the exact substrates and mechanisms remain elusive.Objectives: The objective of this study is to present a spiking thalamocortical model to explore potential alpha generator hypotheses. The study investigates two candidate mechanisms for alpha generation: 1) rhythmic bursts around 10 Hz produced by pyramidal neurons in L5 [1]; and 2) a thalamocortical loop delay of approximately 100 ms suggested in previous mean-field models [2].Materials and Methods: The model encompasses the primary visual cortex and the lateral geniculate nucleus. The cortical component represents 1 mm2 of cortical surface. It is partitioned into four layers (L2/3, L4, L5, and L6), each comprising excitatory and inhibitory spiking neurons modeled using the adaptive exponential integrate-and-fire model. The thalamic network, composed of excitatory and inhibitory populations, is simulated with the same neuron model. Thalamocortical connections are established onto cortical neurons in L4 and L6, with reciprocal feedback from L6 neurons to the thalamus. Based on estimated current source density signals from simulated spiking activity, we compared spectra and Granger causality with experimental data. All network simulations were conducted using the NEST simulator. Results and Conclusions: We analyzed the spontaneous activity of the cortical microcircuit and tested the two hypotheses independently within the model. The findings demonstrate that both mechanisms can support alpha oscillations, albeit with distinct laminar patterns. Hypothesis 1 suggests that Granger causality within the alpha range primarily originates from L5 and L2/3, in a pattern resembling top-down propagation from higher cortical areas, as seen experimentally in a previous study [3]. Hypothesis 2 points to L4 and L6 as the main source layers, corresponding to a bottom-up pattern (from thalamus to cortex), similar to the pattern reported in another experimental study [4]. Combining both mechanisms results in a summation of effects, with the alpha oscillation emanating from all layers. The findings suggest that the two mechanisms may contribute differently to alpha rhythms, with distinct laminar patterns, and may be expressed either separately or in tandem under different conditions.
Genre and audience response in the Middle English Pearl
Creators: name: Amy, Roger Andrew
Publisher: name: University of British Columbia

description: The following thesis, “Genre and Audience Response in the Middle English Pearl”, examines the problematic nature of generic definition of the Middle English poem Pearl. The anonymous poem, dating from the late 14th Century, concerns a "jueler" who has lost a precious pearl and given in to unseemly grief, denying his faith. In a dreamlike vision, he is led through debates by a mysterious Pearl Maiden who shows him the errors he has committed; he is privileged to a heavenly apparition of the heavenly Jerusalem and its divine inhabitants; finally, he is cast from the vision, reconciled to his loss and his faith. Pearl has resisted easy generic categorization. In this thesis, I argue that the indeterminability of the poem's genre is deliberate. Genre carries meaning; a reader, recognizing familiar generic aspects, expects the poem to progress in a certain manner. The poet carefully chooses elements of many familiar genres in order to manipulate the audience's reactions at crucial points in the poem. With these manipulations, the poet succeeds in making the experience of the poem personal for the reader, not merely literary. I begin my argument by postulating the existence of a generic tradition, a historically viewed body of works; genre is the synchronic cross-section of the generic tradition. Following Jauss, I propose that generic tradition shapes the expectations of a reader, and thus shapes the reader's response to a text. I then look at the various generic traditions which Pearl draws from: allegory and elegy, the consolatio, debate poetry, the dream vision, and the visual arts. Using a survey of critical literature and comparisons to other contemporary texts where applicable, I demonstrate how Pearl draws from the various traditions, and where it differs. I then examine the significance of the variations from the generic tradition to the reader's response to the poem. To conclude, I discuss the role of the retrospective look to the reader's understanding of the poem and to the reception and continuation of the generic tradition.
