Résumé :
Seeking for broad and inclusive ways of framing ethical debates on emerging technologies, in this article the authors explore imaginaries of body enhancement as encompassed in the science fiction (sci-fi) literature. They provide in-depth descriptions of three sci-fi novels: Neuromancer, The Player of Games, and Kéthani. They explore how ethical concerns are framed within the imaginary world of these novels, emphasizing that this framing is usually ambivalent, embedded within lived narratives, as well as future and collectively oriented. Because they evoke shared imaginaries, sci-fi novels appear as useful to trigger debate on new technologies.

Résumé :
"Richard III with aliens" is how Cornell (102) describes "Sins of the Father," an episode of Star Trek: The Next Generation (hereafter TNG) in which the Klingon warrior Worf, son of Mogh, seeks to restore his family's honour by exposing and challenging those responsible for falsely accusing his dead father of treason to the Klingon Empire. Worf is only pardy successful in his quest, and he remains a perpetually marginal figure whose identity is divided by his Klingon heritage, his childhood as a Klingon orphan raised by humans, and his current status as the only Klingon in Starfleet, the military arm of the Federation of Planets, an alliance of Earth and other worlds whose relationship with the Klingon Empire is marked by tension, suspicion and, at times, open hostility. As a result of these divisions and struggles, Worf's family is eventually stripped of its wealth and rank on the Klingon home-world, and Worf's brother Kurn seeks a ritual death as the only way to absolve his own and his family's disgrace.

Résumé :
Multimedia artist Astria Suparak’s short video essay, Virtually Asian (2021) presents an astute critique of the racism embedded in pop-culture imaginings of the future. Weaving together footage culled from forty years of science fiction blockbusters, the supercut reveals not only how Asian actors have been used as an orientalist backdrop for white characters in these films, but that these Asian bodies are often dematerialized, represented as projections, holograms, and digital images. The piece comprises a trenchant follow-up to scholar Wendy Chun’s observations about “High-tech Orientalism,” a trope which represents a technologically-advanced future as an exotic Asian landscape. Commissioned by the Berkeley Art Center as part of an online exhibition launched while the gallery was closed by the pandemic, Virtually Asian is part of Suparak's ongoing project, “Asian futures, without Asians.” Despite its sharp critique, Virtually Asian ultimately strikes a hopeful tone. These are after all collective visions of the future: we have the capacity to imagine futures that are less racist, less sexist, more accurate reflections of the world we hope to inhabit.

Résumé :
Provides an overview of modern domestic and foreign literature, discuss the main and most relevant approaches to the solution of the accumulated problems of transplantation in the 21st century, when, as never before, the acute problem of shortage of donor organs and rejection during transplantation. One of the variants of their solution is the decellularization of the donor organ with subsequent decellularization acellular matrix (ECM) stem cells (SC) of the recipient. Another area, which in recent years very actively developing is bioprinting (3D the same results for bioprinting). For the first time encountered with this innovation, the very essence of creation on the computer using 3D modeling seems to be a history of science fiction, but this is a real example of how well-developed modern medical science. The above options give you the opportunity to solve the main question of transplantation – rejection of the transplanted organ, for patients undergoing surgery, transplantation, forced life to take immunosuppressive drugs that make a person defenseless against infectious agents and opportunistic viral infection. The article presents the main stages already achieved; the philosophy and development prospects of regenerative medicine; the difficulty faced by scientists in the search for suitable options to prevent the development of immune responses, as well as the use of different materials. The decellularization and bioprinting allow you to create the autograft that solves the problem of immune rejection of the transplanted organ. Defined a detailed description of each of the presented directions of development and provides an objective assessment of their effectiveness and possibility of application at this point in time. Examples of the use of the considered techniques, the advantages and disadvantages of each method.

Résumé :
Wandering Earth, released in 2019, is regarded as a phenomenal film that opens the door to Chinese science fiction movies. The Chinese story in the film has aroused the resonance of domestic audiences, but failed to get high marks on foreign film review websites. In contrast, in recent years, science fiction films in European and American countries are still loved by audiences at home and abroad, such as The Martian and Interstellar, which have both commercial and artistic values. It can be seen that the cultural communication of western science fiction movies is more successful than that of China. Taking the above three works as examples, this paper analyzes the doomsday plot, the beauty of returning home and the role shaping of scientific women in science fiction movies from the perspective of the organic combination of “hard-core elements of science fiction” and “soft value in humanity”, in an attempt to help the foreign cultural communication of domestic science fiction movies. As an attempt to facilitate the global development of Chinese science fiction, this paper concludes that certain Chinese traditional cultural spirit needs further spreading, that Chinese science fiction and humanity should be combined in a more natural way, and that in particular, female character need in depth and multi-dimensional interpretation.

Résumé :
In the dreams our stuff is made of, Thomas M. Disch talks about the influence and pervasiveness of science Fiction in American culture and asserts the genre's power in “such diverse realms as industrial design and marketing, military strategy, sexual mores, foreign policy, and practical epistemology” (11-12). A few years earlier, Sharona Ben-Tov described science fiction as “a peculiarly American dream”—that is, “a dream upon which, as a nation, we act” (2). Recently, Kim Stanley Robinson has claimed that “rapid technological development on all fronts combined to turn our entire social reality into one giant science fiction novel, which we are all writing together in the great collaboration called history” (1-2). While such diagnostic statements may ring true to American ears, they cannot be taken at face value in the context of Hellenic culture. Despite the unprecedented speed with which the Greeks absorb and consume both the latest technologies (like satellite TV, video, CD and DVD players, electronic games, mobile and cordless phones, PCs, and the Internet) and Hollywood's science fiction blockbuster films, neither technology per se nor science fiction has yet saturated the Greek mind-set to a degree that makes daily life a science-fictional reality. Greek politicians do not consult science fiction writers for military strategy and foreign policy decisions or depend on imaginary scenarios to shape their country's future. Contemporary Hellenic culture does not acquire its national pride from mechanical devices or space conquest. Contrary to the American popular belief that technology is the driving force of history, “a virtually autonomous agent of change” (Marx and Smith xi), the Greek view is that a complex interplay of political, economic, cultural, and technoscientific agencies alters the circumstances of daily life. No hostages to technological determinism, modern Greeks increasingly interface with high-tech inventions, but without locating earthly paradise in their geographic territory and without writing their history or shaping their social reality as “one giant science fiction novel.”

Texte intégral
Résumé :
The history of high-tech regulation is a path studded with incidents. Each adverse event allowed the gathering of more information on high technologies and their impacts on people, infrastructure, and other technologies, posing the bases for their regulation. With the increasing diffusion of artificial intelligence (AI) use, it is plausible that this connection between incidents and high-tech regulation will be confirmed for this technology as well. This study focuses on the role of AI incidents and an efficient strategy of incident data collection and analysis to improve our knowledge of the impact of AI technologies and regulate them better. To pursue this objective, the paper first analyses the evolution of high-tech regulation in the aftermath of incidents. Second, the paper focuses on the recent developments in AI regulation through soft and hard laws. Third, this study assesses the quality of the available AI incident databases and their capacity to provide information useful for opening and regulating the AI black box. This study acknowledges the importance of implementing a strategy for gathering and analysing AI incident data and approving flexible AI regulation that evolves with such a new technology and with the information that we will receive from adverse events—an approach that is also endorsed by the European Commission and its proposal to regulate and harmonise rules on AI.

Résumé :
Effective dissemination of information involves hard work, an ability to write, a sense of timing, some luck, and a capacity to keep things in perspective. More specifically, I think success in publicity and public relations depends on an ability to keep the following considerations or groups of considerations in mind on a regular basis:1. What is the message or information to be conveyed?2. Why should this information be shared with others?What are the real motivations behind the desire to communicate it?3. What audiences could this information be transmitted to? Which should it go to preferably?4. What is the best medium to transmit the information? Which other media may also be effective?5. To what degree are intermediaries required to deliver this information? What are the chances of their misediting the material? Are the risks of a foul-up worth the potential benefits of sending the information through second or third parties?6. When is the best time to disseminate the material?7. Can the effectiveness of this campaign be assessed for each target audience? If so, how? If not, why?Communication is a tremendously complex process. No two people perceive the world in exactly the same manner—nor do they encode or decode messages identically (see Bugenthal et al., 1970). Indeed, the subtleties of communication are so fine that even the most carefully constructed message runs definite risks as it is transmitted from one person to another (see Knapp, 1972). In short, we should probably always assume that others will interpret our message somewhat differently from the way in which we intend it to be received.

Résumé :
Since 2010s growth of the biggest Internet corporations (Big Tech) formed new monopolization challenges, from takeovers of competing start-ups to anti-competitive practices. Initially, regulators were not active, considering complexity of antitrust policies for the high-tech sector (e.g., not to demotivate R&D investments) and specifics of Internet markets (network effects, etc.). But since 2020 situation changed dramatically. Despite the active EU’s role in developing model digital norms, special attention should be paid to the U.S.A. and China (as countries of origin of Big Tech and key Internet markets). In both economies, regulators previously executed a non-restrictive approach to the Internet markets and Big Tech, also as factor supporting their development and global leadership. But rising challenges and political events triggered new antitrust attack. For the PRC it was Jack Ma’s speech amid rising concerns of the CPC leaders about income asymmetries. In the U.S.A. it was Trumpists’ war on the “liberal media” and changes in long-term “alliance” between Democrats and Big Tech. Since 2020 China started antitrust investigations against Big Tech and other Internet corporations, imposed fines, and developed new regulations. In the U.S.A., due to the specifics of the legal and political system, focus was made on forming political and legal basis for further regulatory actions. Several lawsuits were initiated, critics of Internet monopolies were assigned on key positions in federal antitrust bodies, while Congress elaborated draft acts. Theoretical analysis shows that in both nations focus was made on the sharpest (for society and politicians) changes. New initiatives do not pose a threat to Big Tech’s innovation activities yet. Less obvious is their correspondence to the digital economy specifics. So, it is still hard to understand whether these actions will lead to rise of innovations and competition. Long-term systematic development of regulation is needed – as well as serious theoretical research on “digital antitrust”.

Résumé :

The dissertation brings together approaches across the fields of physics, critical theory, literary studies, philosophy of physics, sociology of science, and history of science to synthesize a hybrid approach for instigating more rigorous and intense cross-disciplinary interrogations between the sciences and the humanities. I explore the concept of speculation in particle physics and science fiction to examine emergent critical approaches for working in the two areas of literature and physics (the latter through critical science studies), but with the expectation of contributing new insights to media theory, critical code studies, and also the science studies of science fiction.

There are two levels of conversations going on in the dissertation; at the first level, the discussion is centered on a critical historiography and philosophical implications of the discovery Higgs boson in relation to its position at the intersection of old (current) and the potential for new possibilities in quantum physics; I then position my findings on the Higgs boson in connection to the double-slit experiment that represents foundational inquiries into quantum physics, to demonstrate the bridge between fundamental physics and high energy particle physics. The conceptualization of the variants of the double-slit experiment informs the aforementioned critical comparisons. At the second level of the conversation, theories are produced from a close study of the physics objects as speculative engine for new knowledge generation that are then reconceptualized and re-articulated for extrapolation into the speculative ontology of hard science fiction, particularly the hard science fiction written with the double intent of speaking to the science while producing imaginative and socially conscious science through the literary affordances of science fiction. The works of science fiction examined here demonstrate the tension between the internal values of physics in the practice of theory and experiment and questions on ethics, culture, and morality.

Nevertheless, the dissertation hopes to show the beginnings of a possibility, through the contentious but generative space provided by speculative physics, to produce more cross-collaborative thinking between physics as represented by the hard sciences, and science fiction representing the objects of literary enterprise and creative evolution.

Résumé :
This chapter argues that science fiction is hard reading because it requires the reader to process information at a level additional to that required for the reading of all fiction. The vital feature which distinguished the genre is the presence of the novum, a discrete item of information which the reader recognises as not present in the real world. Such items need first to be recognised and then collated to create an alternative vision of reality, the whole process having been described by the critic Darko Suvin as cognitive dissonance: the dissonance demanding recognition, the collation adding the cognitive element. Science fiction is a high information literature, information being used here in the technical sense of information theory.

Artificial intelligence is outpacing laws, social norms, school curriculum, and the comprehension of most people worldwide, making the high-tech society no longer science fiction. The rapid widespread of numerous AI initiatives in schools, primarily propelled by incentives that could not align well with the long-term educational goals such as social-emotional learning, diversity, equity, and inclusivity. Educators and business leaders play a crucial role in shaping our collective understanding of the landscape and its implications for the future of education and the economy. This empirical study explored the practical understanding of the gap between education and technology in the impending high tech industrial revolution by deep delving into the lived experiences of intellectuals who are currently leading educators and business executives in the United States. The findings on the investigated phenomenon are breaking new ground to bridge the gap between the growth of AI and education.

Résumé :
Ex Machina plays against type extremely well, and it is, in part, particularly effective because of the genre tropes are relatively consistent. There’s really only one term to cinematically describe a reclusive, temperamental genius working on a project he hopes will change humanity: the mad scientist. In the history of science fiction film, the mad scientist has traditionally either been directly responsible for a crisis (potential or realized) by creating the problem, or indirectly responsible by trying to control something so powerful that no one could possibly control it. The latter was used largely in the 1950s and 1970s by reflecting the two perceived threats during those eras: atomic/nuclear power and pollution, respectively. But in these films, the extent of the power being studied must be balanced against what that scientist is trying to accomplish. In Ex Machina, Nathan’s portrayal is a fascinating one, embodying the Silicon Valley, “work hard, play hard” bro-culture we see in the U.S. tech industry, and he’s able to completely detach his own actions/desires from his work, a cognitive dissonance that allows him to create a line of slaves at the same time he tries to reproduce artificial intelligence. This chapter will place Nathan within the larger context of science fiction’s history of mad scientists, analyzing similarities and determining what those differences mean.

Résumé :
Chapter 4 begins with Ian Bogost’s satirical Facebook game Cow Clicker and its send-up of the “gamification” movement to add quantification and algorithmic thinking to many facets of everyday life. Such games trouble the boundaries between work and play, as do much more serious forms of gamification like Uber and the high-tech warehouse workers whose every second and step are measured for efficiency. Taken together, these new models of work herald a novel form of alienated labor for the algorithmic age. In our science fiction present, humans are processors handling simple tasks assigned by an algorithmic apparatus. Drawing on the historical figure of the automaton, a remarkable collection of Mechanical Turk-powered poetry titled Of the Subcontract, and Adam Smith’s conception of empathy in his Theory of Moral Sentiments, the chapter explores the consequences of computational capitalism on politics, empathy, and social value.

Résumé :
This chapter reviews the collection of dioramas at the Civic Museum of Natural History in Milan. Diorama dates back to the era before widespread access to color photography, not to mention to a time when free digital access to information and graphical media would have been considered science fiction. Indeed, everything one sees in a diorama is a collaboration of science and craft or science and art. Yet the diorama form is very much alive and well in natural history museums around the world. The chapter then considers the role of the plane of glass that separates the audience from the world of the diorama. Ultimately, it may be that the quaintness and old-world quality of dioramas have something to do with the way they invite pretend to happen, and with it play. This may also explain the remarkable fact that, despite their quaintness, diorama thrives as an exhibition mode in today's high-tech culture.

Résumé :
With the popular utopian novel well established by 1875, a growing number of writers entered the scene, each offering their take on the problems of the city and the promises of high-tech suburban life. Benjamin Ward Richardson, a famous physician, made an international splash with his vision of Hygeia, a City of Health, promising to deploy green spaces and leverage new building materials to create modern, happy communities. Critics and designers responded in droves, with several rejecting Richardson’s reformed urbanism as too dense, while others committed to actually building Hygeia-inspired suburbs. The first science-fiction dystopian novels were also published in these years, prophesying monstrous, swarming metropolises where human life would be devalued by rampant materialism and pervasive artificiality. Thus, the ideal future of the happy, healthy suburb received its literary foil: the megacity of inhuman density and anonymity. The cumulative message was clear: a life in gardens is the only hope.

Résumé :
Particle Heating Receivers (PHR) offer a range of advantages for concentrator solar power (CSP). PHRs can facilitate higher operating temperatures (>700°C), they can allow for inexpensive direct storage, and they can be integrated into cavity receiver designs for high collection efficiency. In operation, PHRs use solid particles that are irradiated and heated directly as they fall through a region exposed to concentrated sunlight. The heated particles can subsequently be stored in insulated bins, with the stored thermal energy reclaimed via heat exchanger to secondary working fluid for the power cycle in CSP. In this field Georgia Tech has over five years’ experience developing PHR technology through the support of the DOE SunShot program and similar research efforts. Georgia Tech has dealt with the crucial challenges in particle receiver technology: particulate flow behavior, particulate handling, and particulate heat transfer. In particular, Georgia Tech has specialized in innovative advances in the utilization and design of discrete structures in PHRs (DS-PHR) to prolong particulate residence time in the irradiated zone. This paper describes the development and results of lab-scale testing for DS-PHRs especially in the Georgia Tech high flux solar simulator (GTHFSS). The GTHFSS is a bank of high intensity xenon lamps with elliptical reflectors designed to replicate a concentrated solar source. Two series of tests have been undertaken: batch and continuous operation. Initially the DS-PHR has been tested in a batch apparatus in which a substantial but still limited quantity of preheated particulate flows through from an elevated bin through the irradiated PHR into a weighing box collecting bin. The use of a weighing box is advantageous since the flow rate of particulate is otherwise especially hard to measure. Temperature rise measurements and mass flow rate measurements allow calculation of energy collection rates. Calorimetry measurements, also described in the paper, are used to verify the incident concentrated radiation allowing the calculation of the collection efficiency. This preliminary series of experiments have been completed using the batch apparatus, with the efficiencies of the lab-scale DS-PHR being determined for a range of temperatures. Efficiencies above 90% have been measured at low temperatures roughly corresponding to the so-called optical efficiency, which is the rate of energy collection at low temperature and minimal heat loss. Batch experiment data indicates a collection efficiency of approximately 81–85% at an average particle operating temperature of 500°C. Lab-scale batch results at 700°C in proved to be unstable, and as such a rework employing a continuous recirculation loop is underway. While the batch apparatus is convenient for preliminary work, it is challenging to reach steady state operation in the mixing and measurement section below the DS-PHR, which limits this apparatus in higher temperature experiments. Consequently, the experiment is being reconfigured for continuous flow, in which the particulate will be heated and recirculated by a high temperature air conveyor. The advantage of the high temperature conveyor has already been proved by its successful integration as a heater and mixer in the hot bin of the batch apparatus. Such a compact device was also quite advantageous in the limited confines of a typical laboratory simulator such as the GTHFSS. While continuous flow prevents the exceedingly desirable use of an uninterrupted mass measurement device, highly accurate mass flow data is still expected based on the use of a perforated plate flow control station. This device relies on the Berverloo effect to maintain a constant flow of particulate through an array of orifices, for which the flow is largely independent of upstream conditions. A weighing box will be used to calibrate and verify the mass flow. This paper will report on efficiency measurements with the batch flow experiments and present the preliminary steps taken to conduct the recirculation experiment. The bulk the research reported in the paper is sponsored by and done in support of the DoE Sun Shot initiative.

Résumé :
Traditional teaching practices in Ireland for “hard”-science subjects, such as Physics or Engineering, are still prevalently based on whiteboard content delivery, PowerPoint-based methods, and sometimes, within under-funded purposed-built teaching labs, leaving very little manoeuvre or willingness to incorporate student interaction, in addition to a strong focus on end of semester exam based assessment of learning. Very often any deviation from traditional methods of teaching and assessment are perceived as “dumbing down” the course. The proposal of this Lightning Talk is to show how enabling flexibility in the teaching environment, by incorporating either topical research discussions or bringing a high-tech research lab to a teaching module, can stimulate student engagement, curiosity, discovery and learning. Moreover, the talk will also contain a discussion on using different assessment techniques, such as consultation surveys and reports, where a richer picture of true understanding can be drafted, and compare outcomes between report-based and exam-based types of assessment, showing no signs of “dumbing down”.

Résumé :
Protein has a singularly prominent place in discussions about food. It symbolises fitness, strength and masculinity, motherhood and care. It is the preferred macronutrient of affluence and education, the mark of a conscientious diet in wealthy countries and of wealth and success elsewhere. Through its association with livestock it stands for pastoral beauty and tradition. It is the high-tech food of science fiction, and in discussions of changing agricultural systems it is the pivotal nutrient around which good and bad futures revolve. There is no denying that we need protein and that engaging with how we produce and consume it is a crucial part of our response to the environmental crises. But discussions of these issues are affected by their cultural context—shaped by the power of protein. Given this, we argue that it is vital to map that cultural power and understand its origins. This paper explores the history of nutritional science and international development in the Global North with a focus on describing how protein gained its cultural meanings. Starting in the first half of the 19th century and running until the mid-1970s, it covers two previous periods when protein rose to singular prominence in food discourse: in the nutritional science of the late-19th century, and in international development in the post-war era. Many parallels emerge, both between these two eras and in comparison with the present day. We hope that this will help to illuminate where and why the symbolism and story of protein outpace the science—and so feed more nuanced dialogue about the future of food.
