description: This report documents the collaborative research concerning recent urban transformations related to mass tourism in
Lisbon (Portugal). The research was conducted under COESO (Collaborative Engagement on Societal Issues), a citizen
science project which involved small scale pilot projects with high intensity collaboration. The pilot project "Mass
tourism's impact on urban communities" resulted from the collaboration of researchers from CRIA (Centre for Research
in Anthropology), and members of the environmentalist NGO ZERO (Association for the Sustainability of the Earth
System). An anthropologist from the CNRS (Centre National de la Recherche Scientifique / French National Centre for
Scientific Research), also working within the COESO project, observed and documented the collaborative processes of
our citizen science pilot project, and contributed to the fieldwork. Through this pilot, CRIA and ZERO were involved in a
co-creation process in which researchers, experts and activists jointly discuss and define objectives, scope and methods
of research. Universidade Autónoma de Lisboa (UAL) and the Junta de Freguesia de Santo António (Santo Antonio Parish
Council, one of Lisbon’s 24 civil parishes) were local partners, providing logistical support and being involved in part of
the activities (see section 2 of this report).

description: We introduce a novel integrated hybrid plasmonic-photonic device for all-optical switching and reading of nanoscale ferrimagnet bits. The racetrack memory made of synthetic ferrimagnetic material with a perpendicular magnetic anisotropy is coupled on to a photonic waveguide onto the indium phosphide membrane on silicon platform. The device which is composed of a double V-shaped gold plasmonic nanoantenna coupled with a photonic crystal cavity can enable switching and reading of the magnetization state in nanoscale magnetic bits by enhancing the absorbed energy density and polar magneto-optical Kerr effect (PMOKE) locally beyond the diffraction limit. Using a three-dimensional finite-difference time-domain method, we numerically show that our device can switch and read the magnetization state in targeted bits down to ~100 nm in the presence of oppositely magnetized background regions in the racetrack with widths of 30 to 120 nm, clearly outperforming a bare photonic waveguide. Our hybrid device tackles the challenges of nonlinear absorption in the waveguide, weak PMOKE, and size mismatch between spintronics and integrated photonics. Thus, it provides missing link between the integrated photonics and nanoscale spintronics, expediting the development of ultrafast and energy efficient advanced on-chip applications.

description: Sensitive measurement of electrical signals is at the heart of modern science and technology. According to quantum mechanics, any detector or amplifier is required to add a certain amount of noise to the signal, equaling at best the energy of quantum fluctuations. The quantum limit of added noise has nearly been reached with superconducting devices which take advantage of nonlinearities in Josephson junctions. Here, we introduce a new paradigm of amplification of microwave signals with the help of a mechanical oscillator. By relying on the radiation pressure force on a nanomechanical resonator, we provide an experimental demonstration and an analytical description of how the injection of microwaves induces coherent stimulated emission and signal amplification. This scheme, based on two linear oscillators, has the advantage of being conceptually and practically simpler than the Josephson junction devices, and, at the same time, has a high potential to reach quantum limited operation. With a measured signal amplification of 25 decibels and the addition of 20 quanta of noise, we anticipate near quantum-limited mechanical microwave amplification is feasible in various applications involving integrated electrical circuits.

description: While rigorous quantum dynamical simulations of many-body systems are extremely difficult (or impossible) due to the exponential scaling with dimensionality, corresponding classical simulations completely ignore quantum effects. Semiclassical methods are generally more efficient but less accurate than quantum methods, and more accurate but less efficient than classical methods. We find a remarkable exception to this rule by showing that a semiclassical method can be both more accurate and faster than a classical simulation. Specifically, we prove that for the semiclassical dephasing representation the number of trajectories needed to simulate quantum fidelity is independent of dimensionality and also that this semiclassical method is even faster than the most efficient corresponding classical algorithm. Analytical results are confirmed with simulations of quantum fidelity in up to 100 dimensions with 2^1700-dimensional Hilbert space.

description: In this work we focus on two classes of games: XOR nonlocal games and XOR* sequential games with monopartite resources. XOR games have been widely studied in the literature of nonlocal games, and we introduce XOR* games as their natural counterpart within the class of games where a resource system is subjected to a sequence of controlled operations and a final measurement. Examples of XOR* games are $2\rightarrow 1$ quantum random access codes (QRAC) and the CHSH* game introduced by Henaut et al. in [PRA 98,060302(2018)]. We prove, using the diagrammatic language of process theories, that under certain assumptions these two classes of games can be related via an explicit theorem that connects their optimal strategies, and so their classical (Bell) and quantum (Tsirelson) bounds. We also show that two of such assumptions -- the reversibility of transformations and the bi-dimensionality of the resource system in the XOR* games -- are strictly necessary for the theorem to hold by providing explicit counterexamples. We conclude with several examples of pairs of XOR/XOR* games and by discussing in detail the possible resources that power the quantum computational advantages in XOR* games.

Impact of Step Defects on Surface States of Topological Insulators

description: The eigenstates in the presence of a step defect (SD) along $x$ or y axis on the surface of topological insulators are exactly solved. It is shown that unlike the electronic states in conventional metals, the topological surface states across the SD can produce spin rotations. The magnitudes of the spin rotations depend on the height and direction of the SD. The oscillations of local density of states (LDOS) are characterized by a wave vector connecting two points on the hexagonal constant-energy contour at higher energies. The period of the oscillation caused by the SD along y axis is $\sqrt 3$ ($\frac{1}{\sqrt 3}$) times that induced by the SD along x axis at a larger positive (negative) bias voltage. With increasing the bias voltage, the period of the oscillation, insensitive to the strength of the SD, becomes smaller. At lower energies near the Fermi surface, the two types of wave vectors coexist in the LDOS modulations. These results are consistent qualitatively with recent observations of scanning tunneling microscopy.

description: Inflation, a rise in the general price level, affects agriculture in four basic ways. It increases prices of farm products and inputs, encourages farmers to purchase more capital inputs, increases the wealth of those who own the land, and strengthens the relative economic position of high-income people, farm and nonfarm, in buying land. Since the late sixties, changes in prices paid for farm inputs and changes in prices received for farm products have closely corresponded to changes in the general price level. Under inflationary conditions, gains by some often depend on losses by others. This report provides a basis for understanding the causes and effects of inflation as related to agriculture and the conflicting objectives of aiding clientele groups and stopping inflation.

description: In this work we present FreDSNet, a deep learning solution which obtains semantic 3D understanding of indoor environments from single panoramas. Omnidirectional images reveal task-specific advantages when addressing scene understanding problems due to the 360-degree contextual information about the entire environment they provide. However, the inherent characteristics of the omnidirectional images add additional problems to obtain an accurate detection and segmentation of objects or a good depth estimation. To overcome these problems, we exploit convolutions in the frequential domain obtaining a wider receptive field in each convolutional layer. These convolutions allow to leverage the whole context information from omnidirectional images. FreDSNet is the first network that jointly provides monocular depth estimation and semantic segmentation from a single panoramic image exploiting fast Fourier convolutions. Our experiments show that FreDSNet has similar performance as specific state of the art methods for semantic segmentation and depth estimation.

description: Using density functional theory, we investigate TM-cyclopentadienyl-benzene sandwich molecular wires (SMWs) which are composites of TM-cyclopentadienyl and TM-benzene wires (TM = transition metal (V, Fe)). All the SMWs are found to be highly stable ferromagnetic half-metals, showing spin switching behavior. Transport calculations show that finite size clusters display spin filter property when coupled with Au electrodes on either side. I-V characteristics of all systems confirm the spin filter property, with Au-BzVCpVBz-Au displaying exceptionally high performance. In addition to spin filtering, the Au-BzFeCpFeBz-Au system also shows negative differential resistance (NDR). Compression causes an abrupt reduction in magnetic moment and a transition to a metallic phase, while stretching causes an increase in magnetic moment. Half-metallicity is preserved for modest amounts of stretching and compression.
The Representation of Holiness Between Realism and Devotion in the Polyptych of Montefiore dell’Aso by Carlo Crivelli

Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2019

description:

The article seeks to draw attention to the saintly bodies depicted by Crivelli in the polyptych for Montefiore dell’Aso, considering them from different points of view. As written in the introduction, the figures painted by Carlo Crivelli are not simple representations of people, but contain deep religious meanings. The second part of the article focuses on the importance of the technical process of gilding used in the Montefiore panels for the definition of the holy figures, and its significance for a more precise dating. In its third part, the paper suggests a new identification for the Franciscan saint painted in half length with St. Anthony of Padua; the final section looks into Crivelli’s mode of representing the holy bodies of St. Francis and, above all, of St. Louis of Toluse, who wears a ring in which the artist left a previously unnoticed inscription.

In around 1522, the date on his engraving of St. Roch, Nicoletto da Modena reworked a print of St. Sebastian of shared dimensions to create a pendant. In the second state, St. Sebastian is enlarged and placed in the front of the picture plane, focusing our attention on his body. This paper will consider how Nicoletto draws from printmakers including Marcantonio and Campagnola to re-vision his St. Sebastian’s anatomy through sensitive tonal modelling of his flesh. Whether an epidemic of the plague in 1522-4 prompted Nicoletto to make these prints of the plague saints and whether these engravings were issued in Padua, where he is documented from around 1497-1506 will also be considered.

description: Long-ranged attractions across water between two surfaces that are randomly covered with (mobile) positive and negative charge domains have been attributed to induced correlation of the charges (positive lining up with negative) as the surfaces approach. Here we show, by directly measuring normal forces under a rapid shear field, that these attractions may not in fact be due to such correlations. It is rather the inherent interaction-asymmetry between equally- and between oppositely-charged domains that results in the long-ranged attraction even in the complete absence of any charge correlation.

description: Jets and their substructure play a central role in many analyses at the Large Hadron Collider (LHC). To improve the precision of measurements, as well as to enable measurement of jet substructure at increasingly small angular scales, tracking information is often used due to its superior angular resolution and robustness to pile-up. Calculations of track-based observables involve non-perturbative track functions, that absorb infrared divergences in perturbative calculations and describe the transition to charged hadrons. The infrared divergences are directly related to the renormalization group evolution (RGE), and can be systematically computed in perturbation theory. Unlike the standard DGLAP evolution, the RGE of the track functions is non-linear, encoding correlations in the fragmentation process. We compute the next-to-leading order (NLO) evolution of the track functions, which involves in its kernel the full $1\rightarrow3$ splitting function. We discuss in detail how how we implement the evolution equation numerically, and illustrate the size of the NLO corrections. We also show that our equation can be viewed as a master equation for collinear evolution at NLO, by illustrating that by integrating out specific terms, one can derive the evolution for any $N$-hadron fragmentation function. Our results provide a crucial ingredient for obtaining track-based predictions for generic measurements at the LHC, and for improving the description of the collinear dynamics of jets.

description: We consider a full-duplex wireless Distributed Computing (DC) system under the MapReduce framework. New upper and lower bounds on the optimal tradeoff between Normalized Delivery Time (NDT) and computation load are presented. The upper bound strictly improves over the previous reported upper bounds and is based on a novel interference alignment (IA) scheme tailored to the interference cancellation capabilities of MapReduce nodes. The lower bound is proved through information-theoretic converse arguments.
Circulation of Models: Casts from Michelangelo Between Emilia and Veneto, in the Second Half of the Sixteenth Century
Creators: name: Fadda, Elisabetta
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia

description:

In Reggio Emilia, the sculptor Prospero Spani, also known as Clemente (1516-1584), created two statues representing Adam and on the facade of the cathedral. Along with Saint Daria and Saint Crisanto, they were both commissioned in 1552. The two statues indisputably draw inspiration from Dawn and Dusk, which are part of the monument dedicated to Lorenzo de’ Medici in the New Sacristy of San Lorenzo in Florence, work of Michelangelo Buonarroti. In January 1892, Eva’s leg by Prospero Clemente broke and fell to the ground. During the restoration, it was noticed that the leg and all other statues were empty inside. There is no formal documentary evidence of Clemente travelling to Florence, where Buonarroti's New Sacristy was opened to the public in 1556 and where, only later on, by the will of Cosimo I, were carried out some engravings representing the whole composition. Despite the existence of other drawings, casts were mainly responsible for spreading Michelangelo’s inventions for the Medici tombs. In the sixteenth century, it was only possible to talk of a culture of casts after 1540 King Francis I Valois’ initiative to ask Francesco Primaticcio – who was already occupied working for him at the decoration of Fontainebleau – to procure the moulds of Rome’s best ancient statues in order to reproduce them. Among the commissioned casts there were also those from Michelangelo, an artist who was extremely admired by the French. As known, masterpieces realised for the King of France had an immediate impact in Italy, which was primarily possible thanks to Primaticcio’s numerous trips in Emilia, where the painter had his own home and used to recruit his collaborators.

The Electric Body

Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2019

description:

The relationship between the discovery and application of electricity and the human body in the 19th and 20th centuries is complex and multifaceted. Used to stimulate nervous and muscular reactions in the fields of medicine and biology or to record the more intimate movements of the body (cf. the electrocardiogram), electricity established the basis of what today we might call the modern electric – or digital – body. Another aspect, hitherto little explored, is that of the relationship between the electric body and the aesthetics of movement in dance. Visionary choreographers – those who anticipated ‘modern dance’ – such as Vaslav Nijinsky realised that the involuntary movements, often spasmodic and out of control, which electric stimuli could incite (Luigi Galvani comes to mind), could also suggest totally new ideas to the dancer. On the other hand, this kind of movement, syncopated, spasmodic and often uncontrollable, also elicited somewhat morbid analogies with mental disease – a field of research as much ambiguous and equivocal as the new European dance itself wherein hysteria mingled with ecstasy and schizophrenia with emancipation from all conventions. The focus of this essay is on Nijinsky’s choreographic concepts vis-à-vis ecstatic or ‘lunatic’ movement, for his, indeed, was a modern ‘electric body’.

description: Spatial information can be difficult to present to a visually impaired computer user. In this paper we examine a new kind of tactile cueing for non-visual interaction as a potential solution, building on earlier work on vibrotactile Tactons. However, unlike vibrotactile Tactons, we use a pin array to stimulate the finger tip. Here, we describe how to design static and dynamic Tactons by defining their basic components. We then present user tests examining how easy it is to distinguish between different forms of pin array Tactons demonstrating accurate Tacton sets to represent directions. These experiments demonstrate usable patterns for static, wave and blinking pin array Tacton sets for guiding a user in one of eight directions. A study is then described that shows the benefits of structuring Tactons to convey information through multiple parameters of the signal. By using multiple independent parameters for a Tacton, this study demonstrates participants perceive more information through a single Tacton. Two applications using these Tactons are then presented: a maze exploration application and an electric circuit exploration application designed for use by and tested with visually impaired users.

Moreover, we show that the weak Lebesgue norm is best possible in the sense that it is the endpoint for the 'Weiss conjecture' within the scale of Lorentz spaces $L^{p,q}$.
Inhibition of the phosphatidylinositol-3-kinase pathway is selectively cytotoxic to primitive and mature acute myeloid leukemia progenitor cells while sparing their normal counterparts
Creators: name: Muranyi, Andrew L.
Publisher: name: University of British Columbia
Year: 2009

description: Acute myeloid leukemia (AML) is a disorder of the hematopoietic system in which there is an overproduction of immature myeloblast (blast) cells in the bone marrow and suppression of normal hematopoiesis. Like normal hematopoiesis, AML is structured hierarchically and is maintained by rare progenitor cells capable of self-renewal and production of large numbers of leukemic blasts. These rare cells, leukemia-initiating cells (L-IC), are capable of engraftment and proliferation in immunocompromised mice. Dysregulation of signal transduction pathways are frequent occurrences in AML, leading to enhanced cell proliferation and resistance to apoptosis. Pathways which are frequently constitutively active in AML blasts include the phosphatidylinosityl-3-kinase (PI3K) and FMS-like tyrosine kinase 3 (FLT3) receptor signalling pathways. Constitutive PI3K activation, as measured by Akt phosphorylation, was detected in the majority of the 36 AML patient samples tested. The PI3K signalling intermediate integrin linked kinase (ILK) was ubiquitously expressed, and FLT3 abundantly expressed although at variable levels. Furthermore, in the five samples tested, ILK and FLT3, as well as PI3K pathway activation, were also detected in CD34+CD38- sorted and quiescent AML cells, populations enriched for L-IC. siRNA inhibition of ILK caused a decrease in AML colony forming cell (CFC) production. To further test the effects of ILK inhibition on AML, the small molecule inhibitor QLT0267 was used. In vitro kinase assays showed that QLT0267 inhibits both ILK and FLT3 kinases to a similar degree. Treatment of AML blasts with QLT0267 caused dose-dependent killing of AML-CFC, with AML samples containing FLT3 mutations being more sensitive to the inhibitor, although some samples with wildtype FLT3 were also effectively killed. Treatment of AML cells with QLT0267 also decreased survival of both primitive leukemic progenitor cells and L-IC in a dose-dependent fashion. In contrast, QLT0267 showed little toxicity toward normal bone marrow progenitors detected in the same assays. When combined with cytarabine or daunorubicin, QLT0267 worked synergistically to kill AML-CFC from a proportion of AML samples tested. Thus, FLT3, ILK, and constitutive PI3K activation are present in L-ICs, and these candidate leukemic stem cells can be eliminated by inhibition of these pathways, while their normal hematopoietic counterparts are spared.
Salvador Dalí, the Hybrid Portraits of the 1920s

Year: 2019

description:

The life and artworks of Salvador Dalí (1904-1989) are closely interconnected and thoroughly documented. Returning to the hybrid portraits painted by the young artist in the 1920s gives us, on the one hand, the chance to recall a phase in his maturing process which, with few exceptions, is often undervalued by art historians and curators, especially those who are not Spanish. On the other, it can allow us to reaffirm Federico García Lorca’s crucial role in their conception and iconic execution between 1925 and 1927. After the influence of the painter Rafael Barradas from Uruguay, Dalí chose the authoritative model of Picasso, the undisputed master. Encouraged by Luis Buñuel, who had moved to Paris, Dalí visited Picasso in 1926. After that meeting he started to paint multiple heads and self-portraits which include García Lorca’s silhouette. As to avant-garde arts and their porous boundaries, the friendship uniting García Lorca, Buñuel and Dalí was fructuous from the time when they lived at the Residencia de Estudiantes in Madrid. In this institution, open to the most original innovations of European culture, certain aesthetic motives emerged which each developed in his own inimitable way: the subject as a mask, the self being the other, the body reduced into pieces of anatomy, putrefied remains, aberrant mix of organic and inorganic stuff.

Cascades of Particles Moving at Finite Velocity in Hyperbolic Spaces

description: A branching process of particles moving at finite velocity over the geodesic lines of the hyperbolic space (Poincaré half-plane and Poincaré disk) is examined. Each particle can split into two particles only once at Poisson paced times and deviates orthogonally when splitted. At time $t$, after $N(t)$ Poisson events, there are $N(t)+1$ particles moving along different geodesic lines. We are able to obtain the exact expression of the mean hyperbolic distance of the center of mass of the cloud of particles. We derive such mean hyperbolic distance from two different and independent ways and we study the behavior of the relevant expression as $t$ increases and for different values of the parameters $c$ (hyperbolic velocity of motion) and $λ$ (rate of reproduction). The mean hyperbolic distance of each moving particle is also examined and a useful representation, as the distance of a randomly stopped particle moving over the main geodesic line, is presented.
Catalytic Role of Waste Tyre Char in the Upgrading of Biomass Pyrolytic Bio-Oil
Creators: name: ZAREI, ALIREZA
Publisher: name: Monash University
Year: 2023
Subjects: Catalysis and mechanisms of reactions

description: This research aims to investigate and improve the catalytic capability of tyre char, an otherwise low-value waste, as an effective catalyst for upgrading bio-oil derived from the pyrolysis of eucalyptus wood chips. Efforts are specifically made to tailor the tyre char properties to improve the catalyst capability in bio-oil deoxidisation as well as its selectivity in production of value-added bio-chemical in bio-oil. Experiments are carried out in a two-stage fixed-bed reactor in the absence and presence of steam at different heating rates.

description: Generative modeling is an unsupervised machine learning framework, that exhibits strong performance in various machine learning tasks. Recently we find several quantum version of generative model, some of which are even proven to have quantum advantage. However, those methods are not directly applicable to construct a generative model for learning a set of quantum states, i.e., ensemble. In this paper, we propose a quantum generative model that can learn quantum ensemble, in an unsupervised machine learning framework. The key idea is to introduce a new loss function calculated based on optimal transport loss, which have been widely used in classical machine learning due to its several good properties; e.g., no need to ensure the common support of two ensembles. We then give in-depth analysis on this measure, such as the scaling property of the approximation error. We also demonstrate the generative modeling with the application to quantum anomaly detection problem, that cannot be handled via existing methods. The proposed model paves the way for a wide application such as the health check of quantum devices and efficient initialization of quantum computation.
The Second Skin

description:

The avant-garde movements and the theatre masters of the early twentieth century opposed to the idea of a realistic and stylistically recreated theatre costume and gave to the stage clothes a symbolic and expressive meaning. The experimentations of the early twentieth century and the more recent research overcome the idea of the identification of the costume with the character to transform the performer’s body in an art object and figurative element that are essential to the visual composition of the entire show. The current article is intended to examine the extremely close link existing between the performer’s body and the position of the theatrical costume.

The Eclipses of a Star: Anna Moffo Between Opera, Cinema, Television
Creators: name: Maione, Paologiovanni
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2019

description:

In the fifties and sixties Anna Moffo built up a very transgressive career. She might herself have thought that it had gone far beyond any limits if she tried to ‘purify’ it for the future generations by manipulating her earnest biographers. She used her own image in a very generous way, facing a ‘new’ world that was undergoing dramatic changes. She accepted all challenges and abandoned herself to them, without really considering the consequences. No other belcanto star ever risked so much: over the last decades many fascinating talented singers have emerged, but only the pioneering spirit, both experimental and shameless, of that age could give way to thoughtless acts and uncontrolled contaminations.

VISUALIZING FEAR: COMPARING HENRY JAMES'S CLASSIC WITH 'THE INNOCENTS
Creators: name: Eleni, Dr. Georgiou, PhD
Publisher: name: ZAP Journals
Year: 2023
Subjects: House Confinement
Covid-19 Pandemic
Henry James
The Turn Of The Screw
Incarcenation

description: This paper explores the parallels between the experience of house confinement during the COVID-19 pandemic and the themes of incarceration and haunting in Henry James's novella The Turn of the Screw. The paper argues that both experiences can lead to feelings of isolation, anxiety, and paranoia, and that both can also give rise to the perception of ghosts or other supernatural phenomena.
The paper begins by discussing the psychological effects of house confinement, drawing on research from the fields of psychology, sociology, and anthropology. It then discusses the themes of incarceration and haunting in The Turn of the Screw, arguing that these themes are both products of the governess's isolation and anxiety.
The paper concludes by discussing the implications of these findings for our understanding of the experience of house confinement during the COVID-19 pandemic. It argues that the parallels between these two experiences can help us to better understand the psychological impact of house confinement, and that they can also help us to develop strategies for coping with these challenges.

description: Following the work of Maldacena and Zhiboedov, we study the implementation of the Coleman-Mandula theorem in the free O(N)/Higher Spin correspondence. In the bi-local framework we first define an S-matrix for scattering of collective dipoles. Its evaluation in the case of free UV fixed point theory leads to the result S=1 stated in the title. We also present an appropriate field transformation that is seen to transform away all the non-linear 1/N interactions of this theory. A change of boundary conditions and/or external potentials results in a nontrivial S-matrix.

Remaking the Body Politic Anew through Mob and Gang
Creators: name: Murrieta Flores, David A.J.
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2019

description:

The aim is to analyse how the British, radical avant-garde collective King Mob (KM) and the American Up Against the Wall Motherfucker (UAWMF) developed an idea of the body rooted in the Gothic and Romantic imagery of the monster and the mob that emphasised the revolutionary potential of ugliness. The body bridged aesthetics and politics, co-extensive with organisational principles that confronted society at large. On the one hand, KM viewed the ugliness of the mob as a physical force whose imagery was strong enough to destabilise the State, while on the other, UAWMF understood the hostility of society towards the body of the hippie as the locus point of a new identity and discourse for it.

Yaoi Media Consumption and Travel Motivation: Evidence From Filipino Viewers of Thai Boys’ Love Series
Creators: name: Lacap, Jean Paolo
Publisher: name: Advances in Southeast Asian Studies
Year: 2023

description: The Thai yaoi culture is getting a lot of attention in several parts of the world. Numerous Thai boy’s love (BL) series are a huge hit in Thailand and other countries. Despite the notable success of Thai yaoi and BL culture, there is less attention given to this topic in past studies and literature. Moreover, no study has investigated how yaoi culture may affect travel motivation. Hence, the present study examines the effect of yaoi media consumption on travel motivation of Filipino viewers of Thai boys’ love series. A prediction approach was employed, and partial least squares (PLS) path modelling was used to measure the hypothesized relationships. The study reveals that all dimensions of cultural proximity significantly affect Thai yaoi media consumption, and Thai yaoi media consumption was found to have an influence on emotional involvement and travel motivation. Emotional involvement was also found to significantly affect travel motivation, and, at the same time, act as a mediator between Thai yaoi media consumption and travel motivation. The current research offers novel theoretical insights about media consumption and its relation to travel motivation in the context of Thai pop-cultural boys’ love series.

The Female Body in the Artistic Research of the Late Twentieth Century
Creators: name: Fantuzzi, Arianna
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2019

description:

Disguised, adorned, placed in space and obsessively controlled, the body exhibited in Vanessa Beecroft’s performances, drawings and photographs, highlights several key themes of contemporary debate, such as identity transformation, desire, gaze and obsession for perfection, shown from the artist’s perspective and impressed on her models’ bodies. The present essay aims to deepen these topics through the works of Vanessa Beecroft, with an emphasis on those realised in the early nineties – among which the drawings of deformed bodies and the compulsive annotations of the Libro del Cibo – and relating them to the contemporary research of Italian female artists, which reveal new declinations of art making, starting from the same subject: the female body and its symbolism.

Year: 2019

description:

Through performative act the artist’s body encounters many typologies of boundaries: the esthetic one, crossed in several moments in Art History, e.g. by the artists involved in Wiener Aktionismus; the politic one, exemplarily undermined by Marina Abramović Rhythm 0; the biological one, analyzed both by Stelarc in his posthuman experiments and by Regina José Galindo in performances such as Exalatión. This essay aims to give answers to the following questions: how do these encounters take place? What do they bring with them? Which is their very purpose?
