This paper presents a description and some developments on Perle’s theory and compositional system known as Twelve-Tone Tonality, a system that, because of its characteristics and fundamentals, is currently associated with Schoenberg dodecaphonic system. Some research has been made in the last few decades in order to develop his model in a Computer Assisted Composition (CAC) environment. After some efforts in order to analyse these prototypes, we realize that in general they were discontinued or outdated. A three-scope proposal is so outlined: Firstly, to simplify the grasp of a system that presents an easily understandable starting premise but afterwards enters a world of unending lists and arrays of letters and numbers; Secondly, to present the implementation process already started using PWGL [1] (see Laurson, 1996; Laurson, 2003; Laurson, 2009). Finally, the model is applied in a short original compositional work, and it is presented and analysed emphasizing the standpoints properties of the system. Some further considerations were made regarding the continuity of this project where the construction of a dedicated PWGL library of Perle’s model reveals a pre-compositional necessary tool. PWGL software was selected due to its specific fitting features: it is based on Common Lisp - perfectly powerful and suitable to process lists of integers — and it is specialized in CAC.

This paper proposes the notion of Nodalism as a means describing contemporary culture and of understanding my own creative practice in electronic music composition. It draws on theories and ideas from Kirby, Bauman, Bourriaud, Deleuze, Guatarri, and Gochenour, to demonstrate how networks of ideas or connectionist neural models of cognitive behaviour can be used to contextualize, understand and become a creative tool for the creation of contemporary electronic music.

This article summarises our Ph.D. thesis – an analytical view on the player-game relationship through the lens of an action-oriented framework, centred on fundamental entities defined as actors, entities through which action is enacted in the game and of which the player and the game system are a part of. With this in mind, the grounding principles of this framework are seeded in a transition of action into experience, based on communicational systems that structure the dynamic formation of networks of actors from which distinct behaviours emerge, which, in turn, promote the enactment of diverse sequences of events establishing narrative, which is a source of experience of the player. Chronology, responsiveness, thinking and actuation, transcoding, focus, depth, and traversal are the 7 dimensions we unveiled through the lens of this action-oriented framework. This work proposes that video games can be regarded as action-based artefacts and a call to awareness for game designers that when designing for action they are working with the foundations on which video games are built upon.  

This article analyzes the exhibition project of Manifesta 10 (St. Petersburg, 2014) as a complex of narratives including media texts and artists’ myths and stories. Two main, mutually affecting themes of the Manifesta 10 narrative are defined as a dialog between classical and contemporary art and an idea of “total work of art” in the context of the theory of “Gesamtkunstwerk”. The basis of the theory was laid by R. Wagner, and it had later continued in contemporary cultural studies in relation to interactivity of contemporary art. Big exhibition projects transform the idea of “total work of art” into the concept of unity of different artistic elements (artistic methods, media, art spaces, mythologies, commentaries, critical texts) in the whole of the exhibition. The curator’s idea of dialog between classical art and contemporary artworks stresses the key role of the Hermitage in the project of Manifesta 10 and demonstrates benefits and disadvantages of an exhibition mega-project in a classical museum. The “big story” about the opposition of contemporary art and tradition consists of minor stories of particular projects in the exhibition. In this regard, the criteria of Manifesta 10’s critical reception and interpretation are considered.

Unicity and existence of bounded solutions are interesting results not just for PDE (Partial Differential Equations) but can also be extended to minimization problems in Calculus of Variations. These results also have a very interesting behavior. The reasoning and research involved in these theoretical results were part of an artistic process in performance art: the performance piece “On Self Codes”. This paper is devoted to the development of possible connections between mathematics research in Calculus of Variations and performance art through a case study. How can one construct a performance art piece inspired on specific research within mathematics, without translation and using intersubjectivities instead? How can we relate two different fields without using them hierarchically? Can we agree on affirming that this type of work is a statement regarding transdisciplinarity, or it maps the ways in which a contemporary body of work can be shaped today? Are these two features incompatible? These are some of the questions that originated this paper.

Self-modification is an ancient human practice; however, for the first time in history, technology is enabling us to modify our lives not only at an existential or experiential level, but also at an informational level. This paper discusses Foucault’s concept of “technologies of the self” as well as some of its recent interpretations within contemporary philosophy of technology. It shows how ICTs have opened new dimensions for humans to transform their bodies, minds, and self-conception. It argues that while ‘traditional’ self-modification is being revolutionised and popularised by ICTs, these systems are also exposing us to potent, and unintentional forms of ontological tinkering. Ultimately, this paper shows how Foucault’s concept can serve as a valuable tool for understanding contemporary human-technology relations.

As digital technologies make a powerful impact on the production of space and software mediates most of our everyday activities, we find ourselves living, working and interacting in the common ground of code and space. The environmental diffusion of computing should be considered in relation to the increasing acceleration and simultaneity of socio-spatial and economic processes, characteristic conditions of a dynamic spatial ontology that evolved during the past decades, changing the ways we inhabit, design and think about our environments. By following the gradual hybridization of space and time, this essay investigates the ways in which software and communication networks infuse space with temporal qualities, enhancing its inherent mediality with successive layers of meaning. An account of this in urban scale is the endeavour of smart cities, a fluid field of tension and negotiation between centralized managerial visions and bottom-up participation and appropriation initiatives. Finally, as spatial production becomes increasingly transdisciplinary and the digital turn reaches a certain level of maturity, the role of the architect and the architectural object changes drastically. Cedric Price famously argued that the best solution to a spatial problem is not necessarily a building, but the question is still pending – could it then be code?

In this work, we established the foundations of a framework with the goal to build an end-to-end naturalistic expressive listening agent. The project was split into modules for recognition of the user’s paralinguistic and nonverbal expressions, prediction of the agent’s reactions, synthesis of the agent’s expressions and data recordings of nonverbal conversation expressions. First, a multimodal multitask deep learning-based emotion classification system was built along with a rule-based visual expression detection system. Then several sequence prediction systems for nonverbal expressions were implemented and compared. Also, an audiovisual concatenation-based synthesis system was implemented. Finally, a naturalistic, dyadic emotional conversation database was collected. We report here the work made for each of these modules and our planned future improvements.

Developed for the context of the V Narrative, Media, and Cognition Colloquium, this article focuses on the narratives generated by the works of Juliana Huxtable and DeForrest Brown Jr. With the intention of focusing on marginal productions, and using “Outwardly Coiling Context Collapse” by DeForrest Brown Jr. and “THERE ARE CERTAIN FACTS THAT CAN NOT BE DISPUTED” by Juliana Huxtable as case studies, this paper tries to understand what narratives try to be asserted, and how are they put in practice by these works. With the help of the contributions made by Patrícia Castello Branco and Levinas, the article concludes that the works of the artist’s move towards the creation of collective narratives with a clear social impact that simultaneously tries to steer away from a dominant historical narrative.

 In this paper, we intend to reflect on how audiovisual performance forces us to rethink the concept of narrativity. After a brief review on the fundamentals of narrative theory and audiovisual performance, we will analyse three cases that illustrate different manifestations of narrativity in audiovisual performance.

This article stands for innovative learning opportunities to social inclusion by film education. The theoretical model is a combined structure coming from approaches and projects of social inclusion by film education. The aim is to describe and analyze the film education process in a project outside school. This research is based on a participant observation research conducted on children in a Brazilian slum. Cinema, as other art forms, is a political and ideological tool that can be used with different purposes. Film education is a strong mediator to facilitate transformative learning, changing one’s dysfunctional views and beliefs about oneself and the world by revising their frames of reference (Mezirow & Taylor, 2009). Films have a unique ability to promote empathy towards a role model, and promote resilience in situations similar to those the role model goes through. Furthermore, media, such as films, is capable of reaching people that might otherwise be uninterested (Buckingham, 2007; Gonnet, 2007; Silverstone, 2005; UNESCO, 2013).  

The figure of Queen Nzinga Mbandi continues to be appreciated in fictional and/or historical narratives as a myth of postcolonial Angolan identity, allowing a continuous approach as to what concerns the modes of cultural representation. In this article, the works of Manuel Pedro Pacavira, Nzinga Mbandi (1975), Pepetela, A gloriosa família: o tempo dos flamengos (1997) and José Eduardo Agualusa, A Rainha Ginga e de como os africanos inventaram o mundo (2014) will be analyzed, as these authors, in different moments of the recent Angolan history, look at this emblematic figure, drawing on historical information produced by Cavazzi, Cadornega or Jean Louis Castilhon, among others. The works now in analysis reiterate the mythical figure of resistance to the European invaders, which was Nzinga Mbandi, or a strong orientation towards the nationalist exaltation supported by it, an evident strategy which, by the rescue of figures and cultural practices, is defined as a means to affirm negritude.

At the border between information and entertainment, memes and newsgames aresome of the news formats that, made viral in social networks, complement the informational experience and compete with the traditional news media in constructing alternative readings of the real. If in the light of Bakhtine (apud Ponte, 2004) journalism can be understood as a secondary discursive genre that feeds on primary genres, how to understand the circulation of these discourses produced from journalistic events in social networks? On the other hand, how are these narratives appropriated by the media? What functions do they play in media discourse? In this article we present some examples of products created from events of political impact for than register, by the analysis of a set of news stories, how the digital press, in the Iberian context, make use of them. The purpose of this article is to contribute to the reflection on how the information media relate to these new narratives.

Artificial intelligence is quietly shaping social structures and private lives. Although it promises parity and efficiency, its computational processes mirror biases of existing power even as often-proprietary data practices and cultural perceptions of computational magic obscure those influences. However, intersectionality—which foregrounds an analysis of institutional power and incorporates queer, feminist, and critical race theories—can help to rethink artificial intelligence. An intersectional framework can be used to analyze the biases and problems built into existing artificial intelligence, as well as to uncover alternative ethics from its counter-histories. This paper calls for the application of intersectional strategies to artificial intelligence at every level, from data to design to implementation, from technologist to user. Drawing on intersectional theories, the research argues these strategies are polyvocal, multimodal, and experimental—suggesting that community-focused and artistic practices can help imagine AI’s intersectional possibilities and help begin to address its biases

In the last years, there has been a surge in AI-powered products. Often marketed as "free", these services operate as hooks to lure unsuspecting users into voluntarily giving up data about every aspect of their life. Their data is the primary fuel of surveillance capitalism, a new economic system that exclusively benefits so-called Big Tech organisations at the expense of personal privacy and freedom of choice. This paper argues the ways these AI-powered products are being imagined and designed is further generalising a kind of, "enframing" that encourages a bureaucratic relationship with the world disguised as (a false sense of) augmented agency. This paper shows that technologically informed philosophical reflections can contribute to getting ourselves back into the feedback loop of technological mediation by helping us recognise our "becoming" with technologies as a design process.

The incorporation of algorithmic procedures into the automation of image production has been gradual, but has reached critical mass over the past century, especially with the advent of photography, the introduction of digital computers and the use of artificial intelligence (AI) and machine learning (ML). Due to the increasingly significant influence algorithmic processes have on visual media, there has been an expansion of the possibilities as to how images may behave, and a consequent struggle to define them. This algorithmic turnhighlights inner tensions within existing notions of the image, namely raising questions regarding the autonomy of machines, author- and viewer- ship, and the veracity of representations. In this sense, algorithmic images hover uncertainly between human and machine as producers and interpreters of visual information, between representational and non-representational, and between visible surface and the processes behind it. This paper gives an introduction to fundamental internal discrepancies which arise within algorithmically produced images, examined through a selection of relevant artistic examples. Focusing on the theme of uncertainty, this investigation considers how algorithmic images contain aspects which conflict with the certitude of computation, and how this contributes to a difficulty in defining images.

This paper presents a novel descriptive model for agency in videogames as communication. Literature pertaining to interactive works including videogames has identified the need to overcome dyadic perspectives of communication in such works. Research specifically to do with agency has called for agency to no longer be confused with freedom of action, for an integrated perspective of the player and the system, and for that relationship to be viewed as a conversation. The transactional model in this paper achieves this by proposing a nested hierarchy of levels of communication that operate as an implicit contract, negotiated between the system and the player, where the object of the transaction is bio-costs, effected through the signalling of the attainability of understandings. The paper describes research antecedents, a research agenda, the basis for the model, the model itself, examples of how the model can be used to describe videogame designs, and future research.

The goal of this research is to characterize representative performances by famous pianists in order to determine main influential trends in performance, derived specifically from traditional piano practices referred to as National Piano Schools. Previous research (Lourenço, 2005, 2007) has shown strong musical correlation of particular characteristics, namely the aesthetic, the technical, the historic and the repertoire. The concept of piano interpretation school is a useful concept for analyzing the universe of piano performance. Piano pedagogy literature of each European National Piano School has been analyzed together with an empirical audio analysis of recordings through a check-list survey. Overall the main National Piano Schools consist of three essential branches: the Russian school; the German school; the French school. The identification of National Piano Schools provides a powerful framework of study and an awareness of Europe's elusive music heritage and it main influences. Furthermore, as pianists use their whole body to enhance their communication of the music's spiritual, emotional and dramatic essence, this study also aims to contribute into research on performance practice.
