El objetivo del presente artículo es identificar diferentes imágenes “orientalistas” en los posters de la industria cinematográfica italiana de los años cincuenta y sesenta dentro de lo que se conoce ...como el género del péplum y demostrar que estas imágenes forman parte de un régimen discursivo orientalista. A su vez, demostrar cómo la construcción de la alteridad en estos afiches se sustenta fuertemente en las representaciones iconográficas decimonónicas pero con un elemento distintivo, el “héroe”, que aglutina en su figura todos los rasgos positivos de la civilización occidental. Para ello se analizaran algunos carteles cinematográficos promocionales de películas italianas hacia mediados del siglo XX con temática del “Próximo Oriente antiguo”, como La Cortigiana di Babilonia de Carlo Ludovico Bragaglia (1954), Io Semiramide de Primo Zeglio (1963), Le sette folgori di Assur de Silvio Amadio (1962) y L´eroe di Babilonia de Siro Marcellini (1963) entre otras.
In questo testo si propone una lettura della peste raccontata nel Decameron che prenda in esame la presenza di possibili stratificazioni o risonanze di fonti antiche e medievali che si possono ...intuire nel racconto che Giovanni Boccaccio offre all’inizio della sua opera, quando narra l’origine e conseguenze della peste scatenatasi nel 1348, terribile avvenimento che fa da sfondo e cornice al racconto. Nelle prossime pagine si prenderà in esame sia il debito che Boccaccio ha con la Historia Longobardorum di Paolo Diacono, considerata la fonte principale da cui attinse l’autore fiorentino per dare voce e corpo alla pestilenza fiorentina del XIV secolo, sia alcuni dettagli che sono presenti nel racconto e che sembrano richiamare altre narrazioni.
In 1968 a team of scientists and engineers from RCA announced the creation of a new form of electronic display that relied upon an obscure set of materials known as liquid crystals. At a time when ...televisions utilized bulky cathode ray tubes to produce an image, these researchers demonstrated how liquid crystals could electronically control the passage of light. One day, they predicted, liquid crystal displays would find a home in clocks, calculators—and maybe even a television that could hang on the wall.Half a century later, RCA's dreams have become a reality, and liquid crystals are the basis of a multibillion-dollar global industry. Yet the company responsible for producing the first LCDs was unable to capitalize upon its invention. In The TVs of Tomorrow, Benjamin Gross explains this contradiction by examining the history of flat-panel display research at RCA from the perspective of the chemists, physicists, electrical engineers, and technicians at the company's central laboratory in Princeton, New Jersey.Drawing upon laboratory notebooks, internal reports, and interviews with key participants, Gross reconstructs the development of the LCD and situates it alongside other efforts to create a thin, lightweight replacement for the television picture tube. He shows how RCA researchers mobilized their technical expertise to secure support for their projects. He also highlights the challenges associated with the commercialization of liquid crystals at RCA and Optel—the RCA spin-off that ultimately manufactured the first LCD wristwatch. The TVs of Tomorrow is a detailed portrait of American innovation during the Cold War, which confirms that success in the electronics industry hinges upon input from both the laboratory and the boardroom.
Qualitative studies regarding the reception or reception of Generation Z on Covid-19 information in Indonesia have not been widely carried out. As a generation that was born and grew up with digital ...technology that is developing very quickly, Gen Z has different characteristics from other generations. Gen Z's acceptance of information related to Covid-19 is one of the important things to assess regarding their potential role and quantity. This study aims to explore Gen-Z's acceptance of Covid-19 information in digital media with a qualitative approach to reception analysis. Data were obtained through FGDs and in-depth interviews. Research findings show that Gen Z prefers access to information that is fast-paced and practical; have a preference for news that is more relaxed, positive and informative; have adequate information literacy to identify hoaxes and perform fact checks; and has a reading position of negotiation and opposition with diverse behavior, but not hegemony-dominant. The results of this study contribute to the qualitative data of Gen-Z reception of Covid-19 information among the available quantitative data.
With Internet access, citizens in non-democracies are often able to diversify their news media repertoires despite government-imposed restrictions on media freedom. The extent to which they do so ...depends on motivations and habits of news consumption. This article presents a qualitative study of the motivations and habits underlying news media repertoires among a group of digitally connected university students in authoritarian Russia. Interviews reveal awareness and dissatisfaction vis-a-vis the ‘propagandistic’ nature of state-controlled news content, resulting in a preference for using multiple different sources – including foreign websites and ‘non-official’ citizen accounts – to build a personal understanding of what is ‘really’ going on. The article then examines how the students make sense of conflicting narratives about international affairs which they encounter in state and non-state sources. Paradoxically, low reported consumption of distrusted, ‘propagandistic’ state television is often accompanied by reproduction of the overarching strategic narrative which state television conveys.
Non-orthogonal multiple access (NOMA) has received considerable recent attention as a promising candidate for 5G systems. A key feature of NOMA is that users with better channel conditions have prior ...information about the messages of other users. This prior knowledge is fully exploited in this letter, where a cooperative NOMA scheme is proposed. The outage probability and diversity order achieved by this cooperative NOMA scheme are analyzed, and an approach based on user pairing is also proposed to reduce system complexity.
Fixed in spatial distribution, arrays of planar, electromechanical acoustic transducers cannot adapt their wave energy focusing abilities unless each transducer is externally controlled, creating ...challenges for the implementation and portability of such beamforming systems. Recently, planar, origami-based structural tessellations are found to facilitate great versatility in system function and properties through kinematic folding. In this research we bridge the physics of acoustics and origami-based design to discover that the simple topological reconfigurations of a Miura-ori-based acoustic array yield many orders of magnitude worth of reversible change in wave energy focusing: a potential for acoustic field morphing easily obtained through deployable, tessellated architectures. Our experimental and theoretical studies directly translate the roles of folding the tessellated array to the adaptations in spectral and spatial wave propagation sensitivities for far field energy transmission. It is shown that kinematic folding rules and flat-foldable tessellated arrays collectively provide novel solutions to the long-standing challenges of conventional, electronically-steered acoustic beamformers. While our examples consider sound radiation from the foldable array in air, linear acoustic reciprocity dictates that the findings may inspire new innovations for acoustic receivers, e.g. adaptive sound absorbers and microphone arrays, as well as concepts that include water-borne waves.
Deciphering the codes of contemporary plastic art requires an intellectual effort, so that communication between the artist and the media outlet can strip away the ambiguity to reach a clear reading ...such that the achievement can be understandably presented to the recipient.
The first chapter serves to identify the problem, the scope of the study. As the issue stems from the ambiguous nature of an artist's piece for media publication, it would derive several questions: What is the level of interest of the Arab press in the field of plastic arts? How willing is the Arab press to actively contribute to the field? And are they open to enhancing the process of understanding or receiving it? The author(s) further elaborate upon the importance and aim of the research that is quantified by the objective and temporal metrics of the study along with relevant, defined terminology. The second chapter covers the two concepts of information and receiving through its design of the study's theoretical framework and the author(s) acknowledgment and citations of prior relevant works. Its third chapter details the procedures by which the researcher(s) would identify a sample populace consisting of chosen relatives and relevant works of art. The fourth chapter, in providing its analysis of the results and the drawn conclusions of the study, gave insight into how media and art can influence an audience's opinions about community issues. Such a connection would notably contribute to the decision-making process and shape the convictions of the individual..
Abstract We present an audience reception study of participant reactions to gender‐based violence in Issa López' 2008 film, Casi Divas , chosen for its nuanced depiction of women grappling with ...several violences. Over three focus groups with 15 adult participants, we used Galtung's conflict theory to explore what participants identified as violence, and how victims should respond to violence in various forms. We find that participants have a narrow definition of violence, seeing it as an individualized act and therefore neglecting to consider its cultural or structural foundations. The participants' responses to violence largely reflected neoliberal values of personal empowerment and choice, resilience, and “leaning in.” We recommend critical visual literacy as a tool in the educational context to identify and address violence, to fight inequity, and to establish emancipatory discourses.
This paper presents a literature review on recent applications and design aspects of the intelligent reflecting surface (IRS) in the future wireless networks. Conventionally, the network optimization ...has been limited to transmission control at two endpoints, i.e., end users and network controller. The fading wireless channel is uncontrollable and becomes one of the main limiting factors for performance improvement. The IRS is composed of a large array of scattering elements, which can be individually configured to generate additional phase shifts to the signal reflections. Hence, it can actively control the signal propagation properties in favor of signal reception, and thus realize the notion of a smart radio environment. As such, the IRS's phase control, combined with the conventional transmission control, can potentially bring performance gain compared to wireless networks without IRS. In this survey, we first introduce basic concepts of the IRS and the realizations of its reconfigurability. Then, we focus on applications of the IRS in wireless communications. We overview different performance metrics and analytical approaches to characterize the performance improvement of IRS-assisted wireless networks. To exploit the performance gain, we discuss the joint optimization of the IRS's phase control and the transceivers' transmission control in different network design problems, e.g., rate maximization and power minimization problems. Furthermore, we extend the discussion of IRS-assisted wireless networks to some emerging use cases. Finally, we highlight important practical challenges and future research directions for realizing IRS-assisted wireless networks in beyond 5G communications.
