Ruins of War : The Green Sea and the Mysterious Island
No full textThis chapter provides a semiotic investigation of an emblematic space in Palermo, the Foro Italico. After the Second World War, this space was occupied for many years by the ruins left when the city was bombed. Analysing the diachronic evolution of the Foro Italico, the author examines the semantic categories that have defined the space, exploring how the memory of the war has been concealed and inscribed in the post-war rewritings of the place. The chapter reads this space as 'a mysterious island', caught between nature and culture. Referring to different kinds of texts, Marrone illustrates how the practices of various local and migrant communities contribute not only to the resemantisation of space but also to the production of new memories

No full textFormalizzazione o accumulazione? Digitalizzazione e dipendenza nelle piattaforme di food delivery
No full textThe paper provides a perspective, empirically explorated in the context of food delivery, able to focus those factors which have developed the digitalizazion of the economy, but also why its benefits are not being redistributed among those who have been involved. The hypothesis is that this happens because digitalization is not only the product of technological development, but also of a ri-articulation of accumulation processes happening in the context of neoliberalism effects on the society. A process which is not only increasing the relevance of food delivery, but it is also transforming social relations inside such context. The paper presents empirical evidences coming from the analysis of four of the major food delivery platforms balance sheet. Furthermore, the author will analyze 5 interviews conducted among food delivery workers and 7 among restaurant’s manager. The author finally underlines how digitalization is producing a dependency from digital platforms which gets deepen by the way in which they operate
Tilted beam measurement of VLBI receiver for the South Pole Telescope
No full textWe have developed a 230 and 345 GHz very-long-baseline interferometry (VLBI) receiver for the South Pole Telescope (SPT). With the receiver installed, the SPT has joined the global Event Horizon Telescope (EHT) array. The receiver optics select the 230 or 345 GHz mixers by rotating the tertiary mirror around the optical axis, directing the chief ray from the secondary mirror to the feed horn of the selected frequency band. The tertiary is installed on top of the receiver cryostat, which contains both mixer assemblies. The feed horns are placed symmetrically across the centerline of the telescope optics and tilted inward by 5.7 degrees from the vertical plane so that their beams intersect at the chief ray intersection on the tertiary mirror. We have performed vector beam measurements of the SPT VLBI receiver in both frequency bands. The measurements preserved the relative location of the beams, to establish the relative locations of the phase centers of the two horns. Measurements in two parallel reference planes above the cryostat were used to suppress reflected light. To model the beam, we derive a general expression of the electric field vector on the measurement plane for a tilted beam and infer the feed horn position parameters for both frequency bands by fitting models to data with a Markov chain Monte Carlo (MCMC) method. The inferred parameters such as the tilt angle of the feed horn are in good agreement with the design. We present the measurement setup, amplitude and phase pattern of the beam, and the fitting result here. © 2018 29th IEEE International Symposium on Space Terahertz Technology, ISSTT 2018.All Rights Reserved
Introduction
No full textPrecisely because Seth’s interest in the past can be mistaken for unadulterated longing, his body of work becomes an ideal site for redressing the somewhat impoverished understanding of nostalgia in contemporary comics. In this book, Marrone locates his work between history and memory, along a spectrum of “ambivalent longing.”
Walter Benjamin describes remembrance as “the capacity for endless interpolation into what has been.” This book re-conceives that comparison as more than just a metaphor: Marrone proposes a relation between interpolation into the past and the reader’s capacity for interpolation into the comics text.
Interpolation, as Marrone has defined it, concerns an ambivalent impulse related to the past that is characteristic of what W. J. T. Mitchell calls “the composite imagetext structure of memory,” which parallels the imagetext structure of comics. Interpolation encapsulates these complex relations, referring to the memory-inflected filling of gaps that comics pages invite the reader to undertake.</p
Epistemic Democracy and Technopolitics: Four Models of Deliberation
No full textIn this article, the author examines the structure of four deliberative models: epistemic democracy,
epistocracy, dystopic algocracy, and utopian algocracy. Epistocracy and algocracy (which in its two
versionsis an extremization of epistocracy) represent a challenge to the alleged epistemic superiority
of democracy: epistocracy for its emphasis on the role of experts; algocracy for its emphasis on
technique as a cognitively and ethically superior tool. In the concluding remarks, the author will
advance the thesis that these challenges can only be answered by emphasizing the value of citizens’
political participation, which can also represent both an increase in their cognitive abilities and a
value for public ethic
Female Journeys: Autobiographical Expressions by French and Italian Women
No full textIn this study of 19th- and 20th-century French and Italian women\u27s autobiography, the author illustrates how the protagonists\u27 development unfolds through separation from oppressive social and familial structures. Reading the selected life stories as bildungsromane and drawing on an array of both canonical and noncanonical texts in the various autobiographical subgenres, Marrone concludes that the heroines\u27 movements away from oppressive structures are not limited to particular historical periods but are motivated by historical and cultural circumstances. She thoughtfully traces the reasons why a 19th-century protagonist might leave her country, a turn-of-the century heroine might flee her family, and a modern female character might separate from her mother, carefully examining their motivations and their goals. In telling their stories, she concludes, women writers continually challenge existing autobiographical conventions. Marrone finds that postmodern texts prove that the journey toward selfhood may be an ongoing one, one that unfolds through the creation of multiple life stories --Amazon.
The author begins her study with a consideration of the tradition of women\u27s autobiography in French and Italian literature of the 19th- and 20th-centuries. Using several examples from various genres, she brings issues of gender oppression, marital abuse, sexuality, and motherhood to the forefront of the discussion. She continues by analyzing the genres of autobiography and bildungsroman—where they overlap and where they diverge, specifically in women\u27s writing. Turning to specific authors and their works, Marrone moves on to an analysis of the writings of Cristina Trivulzio di Belgiojoso, C^D\u27eleste Mogador, Sibilla Aleramo, Oriana Fallaci, Marie Cardinal, and Annie Ernaux. In examining the works of these writers, the author concludes that women writers continue to attempt to define themselves in their own voices. Marrone finds that postmodern writers participate in innovative experimentation in life writing: hybrid texts, creative auto/biographies, and collective life stories
Nicolò Rezzara e le battaglie scolastiche dei cattolici italiani tra Otto e Novecento
No full textDuring the first fifteen years of the XX Century the Italian scholastic debate was animated by two main questions: the control of the state over primary school and the teaching of religion in public schools. Among the various protagonists of those debates, Nicolò Rezzara represented one of the most relevant figures of the Catholic front: author of various books on the school and its legislation, his contribution well represents the evolution of Catholic positions on these issues, hovering between the request of a religiously oriented public school and the opposition to the monopoly regime imposed after the Italian unification. The article aims to highlight the work of this author, which still lacks an in-depth study
LE APORIE DELLA GENERALIZZAZIONE: MARTHA NUSSBAUM E LE EMOZIONI INTELLIGENTI
No full textThe paper discusses the so-called neo-Stoic theory of emotions as presented in Martha Nussbaum’s Upheveals of Thought. The thesis I argue is that her theory has only superficial connections with Stoic theory and engages in a series of truisms that by no means make it a new theory, as the author claims
Fragments of a political discourse. Critical interventions
No full textO presente ensaio defende a pertinência do olhar semiótico sobre a política, assim como o caráter político da pesquisa em semiótica. Por meio de desenvolvimentos acerca da organização discursiva na política contemporânea, e da ideia de discurso político, o autor elabora análises e reflexões acerca de temas e paixões com os quais ele identifica um caminho específico da semiótica para responder aos questionamentos promovidos pelo campo da política. Para isso, realiza intervenções críticas, enquanto postura semiótica fundadora. O trabalho visa também a desconstruir mitos e significações naturalizadas. Tais gestos semióticos são consequência da orientação geral que permite à produção dos discursos: uma postura política e, consequentemente, ética que orienta os processos semióticos de construção e de interpretação dos dispositivos discursivos.This essay defends the relevance of the semiotic regards on politics, as well as the political characteristic of semiotic research. Through the development of discursive organization in contemporary politics and the idea of political discourse, the author analyzes and reflects about the themes and the passions which he identifies a specific path of semiotics to answer the questions raised by the any political fields. For this, it performs critical interventions, as a founding semiotic posture. The work also aims at dismantling naturalized myths and meanings. These semiotic gestures are a consequence of the general orientation that allows the production of discourses: a political and ethical posture that guides the semiotic processes of construction and interpretation of discursive devices
