Abstract:
In quantum mechanics a particle can behave like a particle or a wave. Thus, systems of particles can be likened to a superposition of waves. Since sound can be described as a superposition of frequencies, it can also be described in terms of a system of particles manifest as waves. This metaphor between ‘particle physics’ and sound synthesis is quantitatively developed here, suggested initially from some similarities between the two domains. It is applied to a few fundamental physical principles to show how these can be sonified. The author discusses the process of using a simulated ‘atom trap’ to compose a piece that does not require a physicist to appreciate it. This metaphor blurs the distinctions between science and art, where scientific experiment becomes musical composition, and exploring a musical idea involves playing with particle system dynamics. In the future, methods like these could be used with a real system of particles – the particle accelerator will become an expressive musical instrument, and the particle physicist will become the composerscientist.

Abstract:
Lexicographical words represent things – physical or abstracts – and are also plenty of expressive shapes, which are socially built. The grammatical use of words disseminates denotative meanings and metaphorical effects that engage emotions. The context in which words are placed creates a feedback cycle between the sign and the psychic images that it evokes. Through the analysis of the manuscripts of the Brazilian dramatist, Doc Comparato, we shall observe the movements of experimentation and lexical choice along the creative process of his writing of the script Jamais (Never) - also called Calabar or A tribute to the treason. We are going to verify the changes on the effects of meaning by comparing the reviews applied to the text, following the author’s search for the grammatical shape that gives life to the idea. In order to analyze the metamorphosis of the writing process we shall use the fundaments of Genetic Criticism and the Stylistic to evaluate the results reached by the author – considering that a dramaturgical text is made to be staged and, for being so, must predict the impact of the sounds of words and also the actions that follow them.

Abstract:
Art can be a way, together with Nature, to intercept that landscape and inner climate characterized by the rhythm of silence. That dimension of iridescent calm imbued with creative and vital energy, which pushes towards a universal, seductive, profound sphere. Man can, with courage, abandon himself in this harmony and melody of thoughts that suggest a vast and visionary possibility. Each person has the inner possibility to be Art, to get out of the continuous distortions of daily life, to produce a metamorphosis of one’s life. Art triggers the unconscious side of seeing, a rhythmic, dynamic principle, on which every gesture of maximum spontaneity depends, not touched by the artificial, by masks of fugacity and by false personalities. Without Art, it seems that part of real life is missing. The deep artistic power is fluid, without space or time, pulsating with new forms and substance and creating a new personal identity, contiguous to the real world, which inspires new desires. Many diseases of today and yesterday are produced by the lack of expressiveness or by the repression of personal creativity. Art produces well-being because it is the transformation of unconscious expressive energies, so life for our health.

Abstract:
All chordates share several characteristic features including a dorsal hollow neural tube, a notochord, a pharynx and an endostyle. Unlike other chordate taxa, ascidians have a biphasic life-history with two distinct body plans. During metamorphosis, the larval nerve cord and notochord degenerate and the pharyngeal gill slits and endostyle form. While ascidians, like other marine invertebrates, metamorphose in response to specific environmental cues, it remains unclear how these cues trigger metamorphosis. We have identified a novel gene (Hemps) which encodes a protein with a putative secretion signal sequence and four epidermal growth factor (EGF)-like repeats which is a key regulator of metamorphosis in the ascidian Herdmania curvata. Expression of Hemps increases markedly when the swimming tadpole larva becomes competent to undergo metamorphosis and then during the first 24 hours of metamorphosis. The Hemps protein is localised to the larval papillae and anterior epidermis of the larva in the region known to be required for metamorphosis. When the larva contacts an inductive cue the protein is released, spreading posteriorly and into the tunic as metamorphosis progresses. Metamorphosis is blocked by incubating larvae in anti-Hemps antibodies prior to the addition of the cue. Addition of recombinant Hemps protein to competent larvae induces metamorphosis in a concentration-dependent manner. A subgroup of genes are specifically induced during this process. These results demonstrate that the Hemps protein is a key regulator of ascidian metamorphosis and is distinct from previously described inducers of this process in terrestrial arthropods and aquatic vertebrates.

Abstract:
The three modes of insect postembryonic development are ametaboly, hemimetaboly and holometaboly, the latter being considered the only significant metamorphosis mode. However, the emergence of hemimetaboly, with the genuine innovation of the final moult, represents the origin of insect metamorphosis and a necessary step in the evolution of holometaboly. Hemimetaboly derives from ametaboly and might have appeared as a consequence of wing emergence in Pterygota, in the early Devonian. In extant insects, the final moult is mainly achieved through the degeneration of the prothoracic gland (PG), after the formation of the winged and reproductively competent adult stage. Metamorphosis, including the formation of the mature wings and the degeneration of the PG, is regulated by the MEKRE93 pathway, through which juvenile hormone precludes the adult morphogenesis by repressing the expression of transcription factor E93, which triggers this change. The MEKRE93 pathway appears conserved in extant metamorphosing insects, which suggest that this pathway was operative in the Pterygota last common ancestor. We propose that the final moult, and the consequent hemimetabolan metamorphosis, is a monophyletic innovation and that the role of E93 as a promoter of wing formation and the degeneration of the PG was mechanistically crucial for their emergence. This article is part of the theme issue ‘The evolution of complete metamorphosis’.

Abstract:
Diverse animal taxa metamorphose between larval and juvenile phases in response to bacteria. Although bacteria-induced metamorphosis is widespread among metazoans, little is known about the molecular changes that occur in the animal upon stimulation by bacteria. Larvae of the tubewormHydroides elegansmetamorphose in response to surface-boundPseudoalteromonas luteoviolaceabacteria, producing ordered arrays of phage tail-like metamorphosis-associated contractile structures (MACs). Sequencing theHydroidesgenome and transcripts during five developmental stages revealed that MACs induce the regulation of groups of genes important for tissue remodeling, innate immunity, and mitogen-activated protein kinase (MAPK) signaling. Using two MAC mutations that blockP. luteoviolaceafrom inducing settlement or metamorphosis and three MAPK inhibitors, we established a sequence of bacteria-induced metamorphic events: MACs induce larval settlement; then, particular properties of MACs encoded by a specific locus inP. luteoviolaceainitiate cilia loss and activate metamorphosis-associated transcription; finally, signaling through p38 and c-Jun N-terminal kinase (JNK) MAPK pathways alters gene expression and leads to morphological changes upon initiation of metamorphosis. Our results reveal that the intricate interaction betweenHydroidesandP. luteoviolaceacan be dissected using genomic, genetic, and pharmacological tools.Hydroides' dependency on bacteria for metamorphosis highlights the importance of external stimuli to orchestrate animal development. The conservation ofHydroidesgenome content with distantly related deuterostomes (urchins, sea squirts, and humans) suggests that mechanisms of bacteria-induced metamorphosis inHydroidesmay have conserved features in diverse animals. As a major biofouling agent, insight into the triggers ofHydroidesmetamorphosis might lead to practical strategies for fouling control.

Abstract:
Abstract Romanian composers’ interest in Greek mythology begins with Enescu’s peerless masterpiece – lyrical tragedy Oedipe (1921-1931). The realist-postromantic artistic concept is materialised in the insoluble link between text and music, in the original synthesis of the most expressive compositional means recorded in the tradition of the genre and the openness towards acutely modern elements of musical language. The Romanian opera composed in the knowledge of George Enescu’s score, which premiered in Bucharest in 1958, reflect an additional interest in mythological subject-matter in the poetic form of the ancient tragedies signed by Euripides, Aeschylus and Sophocles. Significant Romanian musical works written in the avant-garde period of 1960 to 1980 – Doru Popovici’s opera Prometeu, Aurel Stroe’s Oedipus at Colonus, Oresteia I – Agamemnon, Oresteia II – The Choephori, Oresteia III – The Eumenides, Pascal Bentoiu’s The Sacrifice of Iphigenia – to which titles of the contemporary art of the stage are added – Cornel Ţăranu’s Oreste & Oedip – propose new philosophical and artistic interpretations of the original myths. At the same time, the mentioned works represent reference points of the multiple and radical transformation of the opera genre in Romanian culture. Emphasising the epic character, a heightened chamber dimension and the alternative extrapolation of the elements in the syncretic complex, developing new modes of performance, of sonic and video transmission – are features of the new style of opera associated to the powerful and simple subject-matter of ancient tragedy. In this sense, radio opera The Sacrifice of Iphigenia (1968) is a significant step in the metamorphosis of the genre, its novel artistic value being confirmed by an important international distinction offered to composer Pascal Bentoiu – Prix Italia of the Italian Radio and Television Broadcasting Company in Rome. The poetic quality of the text quoted from the masterpiece of ancient theatre, Euripides’ Iphigenia in Aulis, the hymnic-oratory character of the music, the economy and expressive capacity of the compositional means configured in the relationship between voice, organ, percussion, electro-acoustic means – can be associated in interpreting the universal major theme: the necessity of virgin sacrifice in the process of durable construction.

Abstract:
Matrix metalloproteinases (MMPs) participate in extracellular matrix remodeling and degradation and have been implicated in playing important roles during organ development and pathological processes. Although it has been hypothesized for > 30 years that collagenase activities are responsible for collagen degradation during tadpole tail resorption, none of the previously cloned amphibian MMPs have been biochemically demonstrated to be collagenases. Here, we report a novel matrix metalloproteinase gene from metamorphosing Xenopus laevis tadpoles. In vitro biochemical studies demonstrate that this Xenopus enzyme is an interstitial collagenase and has an essentially identical enzymatic activity toward a collagen substrate as the human interstitial collagenase. Sequence comparison of this enzyme to other known MMPs suggests that the Xenopus collagenase is not a homologue of any known collagenases but instead represents a novel collagenase, Xenopus collagenase-4 (xCol4, MMP-18). Interestingly, during development, xCol4 is highly expressed only transiently in whole animals, at approximately the time when tadpole feeding begins, suggesting a role during the maturation of the digestive tract. More importantly, during metamorphosis, xCol4 is regulated in a tissue-dependent manner. High levels of its mRNA are present as the tadpole tail resorbs. Similarly, its expression is elevated during hindlimb morphogenesis and intestinal remodeling. In addition, when premetamorphic tadpoles are treated with thyroid hormone, the causative agent of metamorphosis, xCol4 expression is induced in the tail. These results suggest that xCol4 may facilitate larval tissue degeneration and adult organogenesis during amphibian metamorphosis.

This research, linked to the Teaching Post-Graduating Course, Arts Educational field, has been developed in a third (3rd) grade class of the Antônio Alves Ramos school, at the city of Santa Maria, RS. Aimed to know and analyze the under constructing creative process of the Initial Years children, providing time and space to the poetic action-experience, in the interacting with the education of the sensorial aspects. For that, articulates a dialogue with voices and ideas of Bachelard (1988, 1989, 1994), Richter (2005), Duarte Jr. (2001), Martins(1998), Maturana and Varela (2002) and Barbosa (2001, 2002). The methodology used in the research was based in the qualitative nature principles by the action-research. Presents itself as participant research, sustained by experiences of art poetics and fruition of daily school experience, emphasizing the imaginary, the creative process and dimension of being a person, not just the final artistic product. The instruments used for gathering data for this research were participative and free observation, field diary and portfolio. For that, in the creative process of children visual poetics, became obvious that the body carries a history - body time - and we can not teach them how to see, imagine, think or act like the adults. The act of creation demanded differentiated times, since each child understood the world in a different way, in their inexperience - another time aspect - admired, enamored, wondered, curious. The under constructing visual poetics allow with pleasure, internal discoveries which feed the person essence in a way to be able to feel, touch, mix, stick together, shape, plot, collect. Therefore, work with art is to believe in the tuning between pleasure and feeling, emotion and thought to construct a world of significance and significants. A world of colors, words, thoughts and actions, where art and knowledge interact on the poetic work and collaborate significantly in childish formation.
Esta pesquisa vinculada ao Curso de Pós-Graduação em Educação, Linha de Pesquisa em Educação e Artes, foi desenvolvida com uma turma de 3ª série da Escola Antônio Alves Ramos, na cidade de Santa Maria-RS. Objetivou conhecer e analisar o percurso criativo das poéticas visuais em construção de crianças dos Anos Iniciais, proporcionando tempo e espaço para experenciAÇÃO poética, na interação com a educação (do) sensível. Para tanto, articula um diálogo com as vozes e idéias de Bachelard (1988, 1989, 1994), Richter (2005), Duarte Jr.(2001), Martins(1998), Maturana e Varela (2002) e Barbosa (2001, 2002). A metodologia utilizada na pesquisa tem por base os princípios de natureza qualitativa através da pesquisa-ação. Apresentase como pesquisa participante, sustentada na experiência para poetizar e fruir arte no cotidiano escolar, enfatizando o imaginário, o processo poético e as dimensões de pessoalidade, e não apenas o resultado plástico obtido. Os instrumentos de coleta de dados utilizados nesta pesquisa foram: observação livre e participante, diário de campo e portfólio. Para tanto, nos percursos criadores das poéticas visuais das crianças, tornou-se evidente que o corpo traz uma história um tempo corporalizado e que não podemos ensina-las a ver e muito menos a imaginar, pensar e agir como nós adultos. Os fazeres exigiam tempos diferenciados, já que cada criança abordava o mundo de modo diferente, em sua inexperiência outra temporalidade o abordavam encantadas, admiradas, espantadas, instigantes. As poéticas visuais em construção permitiram prazerosamente, descobertas internas que nutrem a essência do sujeito de forma a poder sentir, tocar, misturar, agregar, colar, juntar, modelar, esculpir, traçar. Por isso, trabalhar com a arte é apostar na sintonia do prazer com o sentimento, o afeto e o pensamento para a construção de um mundo de significado e significantes. Um mundo de cores, palavras, pensamentos e ações, onde arte e cognição interagem no trabalho poético e colaboram significativamente na formação infantil.

Abstract:
Broad Complex (BRC) is an ecdysone-pathway gene essential for entry into and progression through metamorphosis in D. melanogaster. Mutations of three BRC complementation groups cause numerous phenotypes, including a common suite of morphogenesis defects involving central nervous system (CNS), adult salivary glands (aSG), and male genitalia. Alternative splicing, of a protein-binding BTB-encoding exon (BTBBRC) to one of four tandemly duplicated, DNA-binding zinc-finger-encoding exons (Z1BRC, Z2BRC, Z3BRC, Z4BRC), produces four BRC isoforms. Highly conserved orthologs of BTBBRC and all four ZBRC were found in silico from Diptera, Lepidoptera, Hymenoptera and Coleoptera, indicating that BRC arose and underwent internal exon duplication before the split of holometalolous orders. Five Tramtrack subfamily members were characterized throughout Holometabola and used to root phylogenetic analyses of ZBRC exons, revealing that Z3BRC is the basal member. All four ZBRC domains, including Z4BRC which has no known essential function, are evolving in a manner consistent with selective constraint. Transgenic rescue and immunohistochemistry were used to explore how different BRC isoforms contribute to their shared tissue-morphogenesis functions at the onset of metamorphosis, when BRC is required for CNS reorganization. As predicted, the common CNS and aSG phenotypes were rescued by BRC-Z1 in rbp mutants, BRC-Z2 in br mutants, and BRC-Z3 in 2Bc mutants. However, the isoforms are required at two developmental stages, with BRC-Z2 and -Z3 required earlier than BRC-Z1. Each isoform had a unique expression pattern in the CNS, with no substantial three-way overlap among them. Z4 is strongly expressed in a novel subset of CNS neurons. The most prominent localizations of BRC-Z1, -Z2, -Z3 corresponded with glia, neuroblasts and neurons, respectively. There appears to be a switch from BRC-Z2 in proliferating cells to BRC-Z1 and BRC-Z3 in differentiating cells. The temporal-requirement and spatial-distribution data suggest that BRC-dependent CNS morphogenesis is the result of multicellular interactions among different cell types at different times. BRC-Z1-expressing glia in prepupae may mediate the final steps of CNS morphogenesis. Lastly, BRC is required for migration and programmed cell death of the ring gland, the site of ecdysone and juvenile hormone production. Therefore, BRC may function in ecdysone auto-regulation.

Abstract:
Ambystoma tigrinum undergoes an obligatory metamorphosis while A. mexicanum fails to metamorphose and exhibits paedomorphosis. While it is clear that salamander paedomorphosis is associated with genetic changes that delay developmental timing, it is not clear when and how these changes manifest during development. It is possible that paedomorphic and metamorphic larvae show equivalent patterns of developmental until late in the larval period, when brain regions become competent to stimulate the release of metamorphic hormones. To test this hypothesis, I compared gene expression patterns between the brains of A. mexicanum and A. t. tigrinum larvae. In support of the developmental equivalence hypothesis, 114 differentially expressed genes (DEGs) were identified in common between the species and all but 2 showed the same temporal pattern of expression. However, more DEGs were identified uniquely from each species. In particular, several genes that are associated with the hypothalamus-pituitaryinterrenal axis, which is implicated in metamorphic regulation in amphibians, exhibited significant expression differences between A. mexicanum and A. t. tigrinum larvae. The results show that metamorphic and paedomorphic modes of development are associated with different transcriptional programs in the brain and these programs diverge during early larval development.

Full text
Abstract:
Unlike many amphibians, the paedomorphic axolotl (Ambystoma mexicanum) rarely undergoes external morphological changes indicative of metamorphosis. However, internally, some axolotl tissues undergo cryptic metamorphic changes. A previous study examined interspecific patterns of larval brain gene expression and found that these species exhibited unique temporal expression patterns that were hypothesized to be morph specific. This thesis tested this hypothesis by examining differences in brain gene expression between juvenile (JUV), paedomorphic (PAED), and metamorphic (MET) axolotls. I identified 828 genes that were expressed differently between JUV, PAED, and MET. Expression estimates from JUV were compared to estimates from PAED and MET brains to identify genes that changed significantly during development. Genes that showed statistically equivalent expression changes across MET and PAED brains provide a glimpse at aging and maturation in an amphibian. The genes that showed statistically different expression estimates between metamorphic and paedomorphic brains provide new functional insights into the maintenance and regulation of paedomorphosis. For genes that were not commonly regulated due to aging, paedomorphs exhibited greater transcriptional similarity to juvenile than metamorphs did to juvenile. Overall, gene expression differences between metamorphic and paedomorphic development exhibit a mosaic pattern of expression as a function of aging and metamorphosis in axolotls.

Abstract:
It is generally thought that in amphibians, thyroid hormones (THs) regulate metamorphosis, while sex steroids (estrogens and androgens) regulate gonadal differentiation. However, inhibition of TH synthesis in frogs alters gonadal differentiation, suggesting instead that these two endocrine axes interact during development. Specifically, THs may be involved in male development, while estrogens may inhibit tadpole metamorphosis. However, we do not currently know the mechanisms that account for these interactions, let alone how such mechanisms may differ between species. To develop and test new hypotheses on the roles of sex steroids and THs, I first examined transcriptional profiles (mRNA) of enzymes and receptors related to sex steroids and THs during embryogenesis and metamorphosis in Silurana tropicalis. Tadpoles were exposed to either an estrogen synthesis inhibitor (fadrozole) or TH (triiodothyronine, T3) during early larval or tadpole development. Acute exposures of S. tropicalis to fadrozole or T3 during early development resulted in increased expression of androgen- and TH-related genes in whole body larvae, while chronic exposure to fadrozole during metamorphosis affected gonadal differentiation but did not affect tadpole development. On the other hand, acute exposure to T3 during metamorphosis increased the expression of androgen-related transcripts both in the brain and gonad. In S. tropicalis, the results suggested that cross-talk is primarily in one direction (i.e., effect of THs on the reproductive axis) with a strong relationship between TH and androgen status. Lastly, I established developmental transcript profiles and investigated T3 regulation of brain and gonad transcripts in Engystomops pustulosus. I then compared these results with S. tropicalis and an earlier study in Lithobates pipiens. While each species developed with similar profiles, they differed in their response to T3. Exposure to T3 resulted in either an increase in androgen-related genes (S. tropicalis) or a decrease in estrogen-related genes (E. pustulosus and L. pipiens). In conclusion, these data demonstrated that cross-talk mechanisms differ among these three evolutionary separate species, but in all cases, T3 appears to affect the balance of sex steroids, stimulating the androgen system and providing potential mechanisms of the masculinising effects of THs. These results will contribute to understanding the mechanisms of hormone interactions and their evolutionary basis in frogs.

Abstract:
In the 1950s and 1960s György Ligeti went through a remarkable transition from writing music in the style of Bartók to working at the cutting edge of the avant-garde. Through careful study of the sketches and drafts, as well as analysis of the finished scores, Metamorphosis in Music takes a detailed look at this compositional evolution. The book begins with Ligeti’s synthesis of folk music and modernism in Musica ricercata and continues through the turn of the 1970s, examining nearly every major work as well as numerous unpublished studies. It shows Ligeti’s early discovery of twelve-tone technique, the influence of electronic music on his orchestral writing, and his involvement with the absurdist Fluxus group, and it argues that the repertoire of techniques he developed in this experimental period was incrementally codified into the composer’s personal style in the mid- and late 1960s. The conclusion looks at Ligeti’s approach to form and expression at the turn of the 1970s, when one phase of his metamorphosis had run its course, and the new challenge of composing an opera loomed on the horizon. Throughout the book, sketch study works alongside comments from interviews—counterbalancing the composer’s crafted public narrative, revealing hidden influences, lingering attachments, and insights into the creative process, and ultimately helping complete the picture of how he found his voice in a generation straddling the divide between the modern and postmodern eras.

Abstract:
The coming years will apparently bring increases in seawater temperatures, salinity fluctuation, and ocean acidity, along with increasing pollution levels and increasing incidences of coastal hypoxic events. We can also expect to see shifting patterns of phytoplankton abundance and nutritional quality. Many such stresses experienced early in development—even among brooded embryos—have been found to influence growth rates, survival, and other fitness characteristics following metamorphosis, sometimes for months, both in laboratory studies and in those in which juveniles were transplanted to the field. The effects are usually negative, but have been seemingly positive in a few studies. Vulnerability can vary among species, and even among the offspring from different parents. The mechanisms through which such “latent effects” are mediated are unclear: energy-balance issues and epigenetic factors—in which gene expression patterns are altered without any changes in DNA sequences—seem to be involved.

Abstract:
Tony Bolden presents an innovative history of funk music focused on the performers, regarding them as intellectuals who fashioned a new aesthetic. Utilizing musicology, literary studies, performance studies, and African American intellectual history, Bolden explores what it means for music, or any cultural artifact, to be funky. Multitudes of African American musicians and dancers created aesthetic frameworks with artistic principles and cultural politics that proved transformative. Bolden approaches the study of funk and black musicians by examining aesthetics, poetics, cultural history, and intellectual history. The study traces the concept of funk from early blues culture to a metamorphosis into a full-fledged artistic framework and a named musical genre in the 1970s, and thereby Bolden presents an alternative reading of the blues tradition. Funk artists, like their blues relatives, tended to contest and contextualize racialized notions of blackness, sexualized notions of gender, and bourgeois notions of artistic value. Funk artists displayed contempt for the status quo and conveyed alternative stylistic concepts and social perspectives through multimedia expression. Bolden argues that on this road to cultural recognition, funk accentuated many of the qualities of black expression that had been stigmatized throughout much of American history.

Abstract:
Ancient literature is full of people, gods, and animals in impressive motion. But while the importance of space has been realized recently, motion has had little attention, for all its prominence in literature, and its interest to ancient philosophy. Motion is bound up with decisions, emotions, character; its specific features are expressive. The book starts with motion in visual art: this leads to the characteristics of literary depiction. Literary works discussed are: Homer’s Iliad; Ovid’s Metamorphoses; Tacitus’ Annals; Sophocles’ Philoctetes and Oedipus at Colonus; Parmenides’ On Nature; Seneca’s Natural Questions. The two narrative poems here diverge rewardingly, as do philosophical poetry and prose; in the prose narrative, as in the philosophical poem, the absence of motion, and metaphorical motion, are important; the dramas scrutinize motion verbally and visually. Each discussion pursues the general roles of motion in a work, with detail on its language of motion; then passages are analysed closely, to show how much emerges when this aspect is scrutinized. A conclusion brings works and passages together. It considers the differences made by genre and by the time of writing. Among aspects of motion which emerge as important are speed, scale, shape of movement, motion and fixity, movement of one person and a group, motion willed and imposed, motion in images and unrealized possibilities. A companion website makes it easier to see passages and analyses together; it offers videos of readings to convey the vitality and subtlety with which motion is portrayed.

Abstract:
This section is devoted to the renewal of music theater, a problem present in Nono's thinking since the early 1950s, and which came to the forefront following his experience with Intolleranza 1960 (a period during which he wrote a group of texts dedicated to the subject). The realization of a “theater of ideas” and a “theater of situations,” inspired by Sartre, dominates a long phase that embraces the central years of Nono's activity, approximately between 1960 and 1977. Thus, perceptible differences appear, in both the conceptual system and the form of expression, between the thoughts expressed in the 1980s in “Toward Prometeo” and Nono's earlier writings. These are indicative of the profound metamorphosis that his thoughts on musical dramaturgy underwent during those years.

Abstract:
In Ovid’s stories one finds metamorphoses where the outward appearance is transformed while the inner being remains the same. This chapter argues that the reverse can occasionally be detected in the poetic language: when an expression is repeated, the appearance (word) is the same while the inner being (meaning) is not. In three cases, from the stories of Echo, Pygmalion, and the plague in Aegina, it is shown that the hidden transformations are subtly signalled by the poet. In the first and third cases, the poet’s hints to the readers have been overlooked; as a result, lines containing one or both of the expressions have been considered interpolations by some critics. Arguments are presented in support of their authenticity, and it is suggested that textual problems which may have arisen from early readers’ failure to catch a hint by the poet can be eliminated in two cases by means of conjectures rather than by bracketing entire lines. In the third case the meaning of a repeated expression undergoes a transformation by reappearing in a different generic surrounding.

Abstract:
Recurrent phenotypes are similar or identical phenotypic traits with discontinuous phylogenetic distributions, which owe their similarity to common ancestry (homology). A recurrent trait may be found as a fixed trait, as an alternative phenotype (one morph of a polymorphism or polyphenism), or as a low-frequency developmental anomaly. Recurrence, then, is the phyletically disjunct appearance of homologous traits. An example is the repeated evolution of larviform (paedomorphic) adults in salamanders. The larviform morph is characterized by retention in the reproductive stage of homologous larval traits such as external gills and a tail. This has involved changes at various points in the hormonal mechanism that controls metamorphosis in all salamanders (chapter 25), perhaps under selection for accelerated reproduction in stressful environments (Whiteman, 1994). As is characteristic of recurrent phenotypes, the occurrence of the reproductive larviform adult morph varies in frequency from one species of salamander to another: it can be absent, an anomaly (<5% of population), a common (>5%) alternative to complete metamorphosis, or a predominant or fixed form. Even within the genus Ambystoma, the unmetamorphosed larviform adult occurs as an occasional anomaly in some populations, as a facultatively expressed alternative phenotype in others (e.g., A. tigrinum) and as a fixed form in others (e.g., A. dumerilii; Collins et al., 1993). All atavisms and reversions (see chapter 12) are examples of recurrence. Discontinuity of expression is expected in combinatorial evolution, where traits are turned off and on and expressed in different combinations due to regulatory change. The growing evidence of homoplasy in phylogenetic studies is important evidence that combinatorial evolution occurs and that homoplasy itself is worthy of study, not just a source of “noise” in cladistics (Wake, 1996a). Homoplasy has been defined as “possession by two or more taxa of a character derived not from the nearest common ancestor but through convergence, parallelism, or reversal”. More simply, homoplasy is the recurrence of similarity in evolution (Sanderson and Hufford, 1996).

Abstract:
Humanity settlement are formed as a result of decisions and actions of different people and become as a form of an identity of integrity. So urban form is influenced by desires, values, beliefs, and human activities, so the study of urban form is the study of its constituent human values and expression of physical aspects of their lifestyles. Before contemporary periods, urban form in Iran, continuity based on former patterns of changes, which was gradual, but after the beginning of the influence of west, one of the most important challenges of urban form in Iran is in the form of short-term changes. Changes occur in a cycle of destruction and construction. This paper use the way of content analysis investigate to texts, document to study form and typo-morphology of residential environment in the city of Mashhad. In the periods of one hundred years shows there is a direct and significant relationship between changes of Iranian lifestyle and metamorphosis of urban form, so that by sequential developments of Iranian lifestyle in a short time, the urban form is responded and metamorphosed and again is created in a new form.
