In 1965, John A. Pope presented a paper entitled 'Two-Dimensional Chart of Quantum Chemistry' to illustrate the inverse relationship between the sophistication of computational methods and the size of molecules under study. This chart, later called the 'hyperbola of quantum chemistry', succinctly summarized the growing tension between the proponents of two different approaches to computation–the ab initio method and semiempirical method–in the early years of electronic digital computers. Examining the development of quantum chemistry after World War II, (...) I focus on the role of computers in shaping disciplinary identity. The availability of high-speed computers in the early 1950s attracted much attention from quantum chemists, and their community took shape through a series of conferences and personal networking. However, this emerging community soon encountered the problem of communication between groups that differed in the degree of reliance they placed on computers. I show the complexity of interactions between computing technology and a scientific discipline, in terms of both forming and splitting the community of quantum chemistry. (shrink)

Digital computers carry out algorithms coded in high level programs. These abstract entities determine what happens at the physical level: they control whether electrons flow through specific transistors at specific times or not, entailing downward causation in both the logical and implementation hierarchies. This paper explores how this is possible in the light of the alleged causal completeness of physics at the bottom level, and highlights the mechanism that enables strong emergence (the manifest causal effectiveness of application programs) (...) to occur. Although synchronic emergence of higher levels from lower levels is manifestly true, diachronic emergence is generically not the case; indeed we give specific examples where it cannot occur because of the causal effectiveness of higher level variables.

The rise of digital and interconnected technology within the workplace, including programs that facilitate monitoring and surveillance of employees is unstoppable. The COVID-19-induced lockdowns and the resulting increase in home office adoption even increased this trend. Apart from major benefits that may come along with such information and communication technologies (e.g., productivity increases, better resource planning, and increased worker safety), they also enable comprehensive Electronic Performance Monitoring (EPM) which may also have negative effects (e.g., increased stress and a (...) reduction in job satisfaction). This conceptual article investigates EPM to better understand the development, adoption, and impact of EPM systems in organizations. The EPM literature published since the 1980s constitutes the basis for this conceptual article. We present a framework which is intended to serve as foundation for future studies. Moreover, we reviewed more than three decades of empirical EPM research and identified six major outcomes that are influenced by the use of an EPM system, as well as a large number of moderator variables. Based on our conceptual analyses and the resulting insights, which also include privacy, ethical, and cultural considerations, we discuss future research opportunities where we also refer to design implications for EPM systems.

Imagine you are an editor at a well respected national magazine with a rich history in photojournalism. The magazine is ready for publication but there is a problem with the cover. The photograph chosen for the cover does not quite fit the vertical format of the magazine and no other picture has all the qualities to best illustrate the cover story. No problem! With a computer, an operator simply moves the objects in the photograph closer together to fit the magazine (...) format perfectly. The finished product is virtually undetectable, even by experts.

Widely recognized as America's premiere photography critic, Coleman took an interest in emerging digital technologies long before his colleagues. In fact, the earliest text in this new book of essays concerning the advent of electronic media is from 1967. The intervening thirty years have found Coleman returning to topics such as digitized images, the shifting concept of intellectual property, the impact of computers on photography as a whole, and the social implications of the Internet and World Wide (...) Web. A wide-ranging selection of essays, lectures, and writings, The Digital Evolution makes for stimulating reading, and should be well received by those familiar with Coleman's previous collection of essays, Critical Focus.

The notion of ‘electronic texts’ has gained universal currency. What, exactly, does this phrase refer to? Most authors answer by describing a set of surface characteristics resulting from the application of computer technology to traditional texts. Such depictions, I want to argue, can be seriously misleading. They presuppose a conventional understanding of ‘text’ in order to make sense of the phenomenon of digitised inscriptions. The simple choice of the phrase ‘electronic text’ suppresses the radical challenge raised by the (...) new medium. Its impact is supposedly captured by modification of an existing concept, so it is hardly surprising that most accounts end up with a typical ambivalence. Electronic texts, we are told, are quite different from—but, at the same time, comparable to—their traditional precursors. Some things that could not be done in the entire history of literacy have become possible nowadays. Yet, it is this very history that provides the background for the understanding of digital processes. Describing something previously unknown by means of well-known categories is bound to lead to these kinds of mildly schizophrenic pronouncements. This chapter discusses their initial plausibility and probes their underlying logic. (shrink)

Over the last 30 years, the computer and videogame has emerged as a popular recreational pastime. While often associated with the artificial and alien, it is my contention that the modern videogame informs on the subject of “nature” and what we consider to be natural. This article delineates some of the “natures” posited in computer game design. It provides a valuable overview of gaming culture and might serve as an introduction to further research on specific game genres. It argues that (...) virtual worlds are currently serving a dual purpose, of reinforcing traditional stereotypes of the natural world, while gradually moving towards radical, new forms of “virtual” nature to contend with. It suggests that the mimicking of biological systems in computer games expresses both our lingering cultural interest in the “great outdoors” and a need to give familiarity and substance to an electronic medium marked by its failure to fit within traditional notions of space and geography.

This book explains, in lay terms, the surprisingly simple system of mathematical logic used in digital computer circuitry. Anecdotal in its style and often funny, it follows the development of this logic system from its origins in Victorian England to its rediscovery in this century as the foundation of all modern computing machinery. ONES AND ZEROS will be enjoyed by anyone who has a general interest in science and technology.

The second edition of Jussi Parikka’s Digital Contagions: A Media Archaeology of Computer Viruses is both a welcome reissue of a canonical text in media archaeology and an important intervention into contemporary techno-political crises like cyberwarfare. Parikka’s book shows how viruses are central to the history of networked computing, while articulating their social connections to political, medical, and cultural discourses. For him, the notion of contagion in digital networks is inseparable from the rise of the computing security industry (...) and the spread of what he calls ‘viral capitalism’: a system of value that leverages viral methodologies to colonize new markets and appropriate revolutionary impulses. Against the purity and commercialism of contemporary consumer electronics, Digital Contagions instead looks to the experiments of early viral programming as offering alternative histories of digital media.

Since technology has been entering into human beings’ everyday life, individuals established a deep relationship with digital technology, thus an embodied link between people and digital instruments has been born. This is particularly evidenced by recent literature about screen time (duration of time spent by the individual in using electronic/digital media like television, smartphone, tablet or computer), it significantly influences different human beings’ dimensions: physical, psychological and neurological functions. Impact of digital technology on human beings (...) can be considered as a result of syntonic functioning in order to improve different people’s life areas (e.g., work, social or intimate relationship, learning), while the dystonic relationship is evidenced as a result of human addiction to digital technology. The present study aims to provide a cognitive and social psychology perspective on how screen time is changing our existences, defining digital technology as a gift which people should be aware of in terms of positive but even negative consequences in everyday life.

In the bitcoin whitepaper, Satoshi Nakamoto (2008: 2) defines an electronic coin as a chain of digital signatures. Many have since defined a bitcoin as a chain of digital signatures. This latter definition continues to appear in reports from central banks, advocacy centers, and governments, as well as in academic papers across the disciplines of law, economics, computer science, cryptography, management, and philosophy. Some have even used it to argue that what we now call bitcoin is not (...) the real bitcoin. The definition fails, however. This is important because the Chain Definition obscures Satoshi’s solution to a dilemma in the design of electronic cash, as well as the truth about bitcoin’s privacy and fungibility. In this article, I explain why the Chain Definition fails and what Satoshi likely endorsed instead. Along the way, I untangle some issues around bitcoin fungibility and clarify some others around the ontology of digital assets. (shrink)

Legal information certification and secured storage combined with documents electronic signature are of great interest when digital documents security and conservation are in concern. Therefore, these new and evolving technologies offer powerful abilities, such as identification, authentication and certification. The latter contribute to increase the global security of legal digital archives conservation and access. However, currently used cryptographic and hash coding concepts cannot intrinsically enclose cognitive information about both the signer and the signed content. Indeed, an evolution (...) of these technologies may be necessary to achieve full text researches within hundreds or thousands of electronically signed documents. This article aims at describing a possible model along with associated processes to create and make use of these new electronic signatures called “meaningful electronic signatures” as opposed to traditional electronic signatures based on bit per bit computation.

In the past two decades digital technologies have fundamentally changed the way we think about, make and use popular music. From the production of multimillion selling pop records to the ubiquitous remix that has become a marker of Web 2.0, the emergence of new music production technologies have had a transformative effect upon 21st Century digital culture. Sonic Technologies examines these issues with a specific focus upon the impact of digitization upon creativity; that is, what musicians, cultural producers (...) and prosumers do. For many, music production has moved out of the professional recording studio and into the home. Using a broad range of examples ranging from experimental electronic music to more mainstream genres, the book examines how contemporary creative practice is shaped by the visual and sonic look and feel of recording technologies such as Digital Audio Workstations.

For commercial purveyors of digital speech, information and entertainment, the biggest threat posed by the Internet isn''t the threat of piracy, but the threat posed by free speech -- speech that doesn''t cost any money. Free speech has the potential to squeeze out expensive speech. A glut of high quality free stuff has the potential to run companies in the business of selling speech out of business. We haven''t had to worry about this before, because speaking in a meaningful (...) way to a large audience was expensive, and people couldn''t afford to do serious mass speaking for free for very long. The Internet has made it much cheaper. It doesn''t take much to give out information to the whole world, every day, for free, for years. And people do. If we are trying to increase the abundant dissemination of information, free speech is good. If we are trying to increase commerce in information, free speech is arguably bad, in that it competes with pay speech. Information merchants would obviously prefer that the only speech in the marketplace be pay speech. In the past two years, commercial content owners have scored significant progress in herding free speakers off the Net. There''s an important synergy between persuading the government to give your industry some friendly new laws or regulations, and using new and old legal tools to make life more difficult or expensive for inconvenient competitors who aren''t necessarily doing anything illegal. Recently, businesses have been able to combine the two strategies to make the Internet a much safer place to sell speech, by making the Internet a less friendly, more dangerous place to give away speech for free.

Purpose– The purpose of this paper is to create a conceptual framework, based on a structured literature review, to analyze the digital disability divide and help find solutions for it. A digital disability divide exists between people with impairments and those without impairments. Multiple studies have shown that people without impairments are less likely to own a computer or have an Internet connection than are people with impairments. However, the digital disability divide is seen in relation not (...) only to access but also to accessibility and use. For people with impairments, new technological innovations offer solutions for everyday challenges, such as finding information, communicating with others and using electronic services.Design/methodology/approach– For this study, 4,778 conference and journal publications were systematically analyzed.Findings– A number of key findings emerged. This field is relatively new, and the literature is highly focused on the technological and social aspects of the digital disability divide, with technology and societal attributes being the core sub-attributes for a comprehensive model. The previous literature did not significantly study the consequences of the financial situation of individuals; rather, the predominant focus was on the have-nots and countries with low income potentials. Furthermore, motivation reveals a compelling case within the digital disability divide subset.Originality/value– The review provides a consolidated view of past research on the general topic of the digital disability divide and the attributes that affect it.

The processes taking place in modern science tend to integrate various scientific disciplines in studying any scientific phenomenon. This explains the search of methodology based on the techniques of different sciences involved in formation of the subject of research, which in this article is represented by the digital music art. Interpreted as a branch of music art with digital specificity, digital music art incorporates electronic music presented by specific, algorithmic, and electronic music. A signature characteristic (...) of digital music art consists in its interdisciplinarity, which suggests the combined effect of separate parts of the system and leads to self-organization, which corresponds with the scientific tasks of synergetics. This substantiates the relevance for elaboration of interdisciplinary methodology for studying digital music art in the context of research mechanisms developed within synergetics. The scientific lies in the analysis of digital art through the prism of the qualities inherent to synergetics. The disciplines united by digital art (mathematics, set theory, probability theory, information theory, combinatorics, game theory, cybernetics, computer science, acoustics, sociology, communication, and biology) are interdisciplinary, which means that in ensemble with other disciplines they form a complex interdisciplinary knowledge of structure of digital music art. At the same time, the disciplines that comprise scientific framework of digital music art are attributed to different sciences: humanities, natural sciences, mathematics, social sciences, and technical sciences. In this context, the research of digital music art is simultaneously of interdisciplinary and multiscientific nature. The author established a peculiar impact of interdisciplinarity upon digital art, which generates the qualities inherent to synergetics – nonlinearity, disequilibrium, openness, chaotic nature, entropy, indeterminacy, and dissipation.

Digital media presents an array of interesting challenges adapting new modes of collaborative, online communication to traditional writing and literary practices at the practical and theoretical levels. For centuries, popular concepts of the modern author, regardless of genre, have emphasized writing as a solo exercise in human communication, while the act of reading remains associated with solitude and individual privacy. "The Community and the Algorithm: A Digital Interactive Poetics" explores important cultural changes in these relationships thanks to the (...) rapid development of digital internet technologies allowing near-instantaneous, synchronous, multimedia interaction across the globe. The radical shift in how we author and consume media as an online, electronic transmission effectively resituates the writing process across the liberal arts as less a solitary act of individual enquiry and reflection, and more an ongoing, collaborative process of creative interaction within a multimedia environment or network. Contributions in this anthology demonstrate a robust history and equally diverse contemporary approach to multimedia interaction for literary and artistic ends. Central to all media formats, computation is explored throughout this volume to critically examine how algorithmic procedures in writing help bring forward many key concepts to building creative communities in a digital environment. Each chapter in this book accordingly introduces readers to various new collaborative experiments using a broad range of different digital media formats, including VR, Natural Language Generation (NLG), and metagaming tools. This book will appeal broadly to students, instructors, and independent artists working in the digital arts, while its emphasis on social interactivity will interest theorists and teachers working in theatre, social media, and cyberpsychology. Its secondary focus on computation and media programming as a site of artistic experimentation will also interest programmers and web designers at various professional levels. (shrink)

Use of electronic health records within clinical encounters is increasingly pervasive. The digital record allows for data storage and sharing to facilitate patient care, billing, research, patient communication and quality-of-care improvement—all at once. However, this multifunctionality is also one of the main reasons care providers struggle with the EHR. These problems have often been described but are rarely approached from a philosophical point of view. We argue that a postphenomenological case study of the EHR could lead to more (...) in-depth insights. We will focus on two concepts—transparency and multistability—and translate them to the specific situation of the EHR. Transparency is closely related to an embodiment relation in which the user becomes less aware of the technology: it fades into the background, becoming a means of experience. A second key concept is that of multistability, referring to how a technology can serve multiple purposes or can have different meanings in different contexts. The EHR in this sense is multistable by design. Future EHR design could incorporate multistable information differently, allowing the provider to focus on patient care when interacting with the EHR. Moreover we argue that the use of the EHR in the daily workflow should become more transparent, while awareness of the computer in the specific context of the patient-provider relationship should increase.

Alan M. Turing, pioneer of computing and WWII codebreaker, is one of the most important and influential thinkers of the twentieth century. In this volume for the first time his key writings are made available to a broad, non-specialist readership. They make fascinating reading both in their own right and for their historic significance: contemporary computational theory, cognitive science, artificial intelligence, and artificial life all spring from this ground-breaking work, which is also rich in philosophical and logical insight. An introduction (...) by leading Turing expert Jack Copeland provides the background and guides the reader through the selection. About Alan Turing Alan Turing FRS OBE, (1912-1954) studied mathematics at King's College, Cambridge. He was elected a Fellow of King's in March 1935, at the age of only 22. In the same year he invented the abstract computing machines - now known simply as Turing machines - on which all subsequent stored-program digital computers are modelled. During 1936-1938 Turing continued his studies, now at Princeton University. He completed a PhD in mathematical logic, analysing the notion of 'intuition' in mathematics and introducing the idea of oracular computation, now fundamental in mathematical recursion theory. An 'oracle' is an abstract device able to solve mathematical problems too difficult for the universal Turing machine. In the summer of 1938 Turing returned to his Fellowship at King's. When WWII started in 1939 he joined the wartime headquarters of the Government Code and Cypher School (GC&CS) at Bletchley Park, Buckinghamshire. Building on earlier work by Polish cryptanalysts, Turing contributed crucially to the design of electro-mechanical machines ('bombes') used to decipher Enigma, the code by means of which the German armed forces sought to protect their radio communications. Turing's work on the version of Enigma used by the German navy was vital to the battle for supremacy in the North Atlantic. He also contributed to the attack on the cyphers known as 'Fish'. Based on binary teleprinter code, Fish was used during the latter part of the war in preference to morse-based Enigma for the encryption of high-level signals, for example messages from Hitler and other members of the German High Command. It is estimated that the work of GC&CS shortened the war in Europe by at least two years. Turing received the Order of the British Empire for the part he played. In 1945, the war over, Turing was recruited to the National Physical Laboratory (NPL) in London, his brief to design and develop an electronic computer - a concrete form of the universal Turing machine. Turing's report setting out his design for the Automatic Computing Engine (ACE) was the first relatively complete specification of an electronic stored-program general-purpose digital computer. Delays beyond Turing's control resulted in NPL's losing the race to build the world's first working electronic stored-program digital computer - an honour that went to the Royal Society Computing Machine Laboratory at Manchester University, in June 1948. Discouraged by the delays at NPL, Turing took up the Deputy Directorship of the Royal Society Computing Machine Laboratory in that year. Turing was a founding father of modern cognitive science and a leading early exponent of the hypothesis that the human brain is in large part a digital computing machine, theorising that the cortex at birth is an 'unorganised machine' which through 'training' becomes organised 'into a universal machine or something like it'. He also pioneered Artificial Intelligence. Turing spent the rest of his short career at Manchester University, being appointed to a specially created Readership in the Theory of Computing in May 1953. He was elected a Fellow of the Royal Society of London in March 1951 (a high honour). (shrink)

Artificial intelligence (AI) is one of the main drivers of what has been described as the “Fourth Industrial Revolution”, as well as the most innovative technology developed to date. It is a pervasive transformative innovation, which needs a new approach. In 2017, the European Parliament introduced the notion of the “electronic person”, which sparked huge debates in philosophical, legal, technological, and other academic settings. The issues related to AI should be examined from an interdisciplinary perspective. In this paper, we (...) examine this legal innovation—that has been proposed by the European Parliament—from not only legal but also technological points of view. In the first section, we define AI and analyse its main characteristics. We argue that, from a technical perspective, it appears premature and probably inappropriate to introduce AI personhood now. In the second section, justifications for the European Parliament’s proposals are explored in contrast with the opposing arguments that have been presented. As the existing mechanisms of liability could be insufficient in scenarios where AI systems cause harm, especially when algorithms of AI learn and evolve on their own, there is a need to depart from traditional liability theories.

The first generation of children to grow up with electronic toys and games saw computers as our “nearest neighbors.” They spoke of computers as rational machines and of people as emotional machines, a fragile formulation destined to be challenged. By the mid-1990s, computational creatures, including robots, were presenting themselves as “relational artifacts,” beings with feelings and needs. One consequence of this development is a crisis in authenticity in many quarters. In an increasing number of situations, people behave (...) as though they no longer place value on living things and authentic emotion. This paper examines watershed moments in the history of human–machine interaction, focusing on the pertinence of relational artifacts to our collective perception of aliveness, life’s purposes, and the implications of relational artifacts for relationships. For now, the exploration of human–robot encounters leads us to questions about the morality of creating believable digital companions that are evocative but not authentic. (shrink)

This paper argues that the ‘brain’ has become a frequently invoked and symptomatic source of metaphorical imagery in our current technologically mediated and dominated culture, through which the distinction between the human and the technological has been and continues to be negotiated, particularly in the context of the increasing ubiquity of electronic and digital technologies. This negotiation has thrown up three distinct, though interrelated, figures. One is the ‘Brain in a Vat’, in which the brain can connect to (...) and even operate solely through electronic technologies. Another is the ‘Electronic’ or, more archaically, ‘Giant Brain’, in which the brain’s functions can be reproduced and exceeded by electronic computing technology. A third is the ‘World’ or ‘Global Brain’, in which the connectivity enabled by information–communications technologies produces and fosters forms of distributed intelligence. This paper will trace the development of these figures and show how they have developed in lockstep throughout the two or three centuries of exponentially accelerating technological advance.

Scientists of many disciplines use theoretical models to explain and predict the dynamics of the world. They often have to rely on digital computer simulations to draw predictions fromthe model. But to deliver phenomenologically adequate results, simulations deviate from the assumptions of the theoretical model. Therefore the role of simulations in scientific explanation demands itself an explanation. This paper analyzes the relation between real-world system, theoretical model, and simulation. It is argued that simulations do not explain processes in the (...) real world directly. The way in which simulations help explaining real-world processes is conceived as indirect, mediated by the theoretical model. Simulacra are characterized further, and turn out to be a priori measurable. This gives a clue to a better understanding of the epistemic role of computer simulations in scientific research.

There are currently considerable confusion and disarray about just how we should view computationalism, connectionism and dynamicism as explanatory frameworks in cognitive science. A key source of this ongoing conflict among the central paradigms in cognitive science is an equivocation on the notion of computation simpliciter. ‘Computation’ is construed differently by computationalism, connectionism, dynamicism and computational neuroscience. I claim that these central paradigms, properly understood, can contribute to an integrated cognitive science. Yet, before this claim can be defended, a better (...) understanding of ‘computation’ is required. ‘Digital computation’ is an ambiguous concept. It is not just the classical dichotomy between analogue and digital computation that is the basis for the equivocation on ‘computation’ simpliciter in cognitive science, but also the diversity of extant accounts of digital computation. There are many answers on what it takes for a system to perform digital computation. Answers to this problem range from Turing machine computation, through the formal manipulation of symbols, the execution of algorithms and others, to the strong-pancomputational thesis, according to which every physical system computes every Turing-computable function. Despite some overlap among them, extant accounts of concrete digital computation are non-equivalent, thus, rendering ‘digital computation’ ambiguous. The objective of this dissertation is twofold. First, it is to promote a clearer understanding of concrete digital computation. Accordingly, my main thesis is that not only are extant accounts of concrete digital computation non-equivalent, but most of them are inadequate. I show that these accounts are not just intensionally different (this is quite trivially the case), but also extensionally distinct. In the course of examining several key accounts of concrete digital computation, I propose the instructional information processing account, according to which digital computation is the processing of discrete data in accordance with finite instructional information. The second objective is to establish the foundational role of computation in cognitive science whilst rejecting the purported representational nature of computation. (shrink)

Throughout what is now the more than 50-year history of the computer many theories have been advanced regarding the contribution this machine would make to changes both in the structure of society and in ways of thinking. Like other theories regarding the future, these should also be taken with a pinch of salt. The history of the development of computer technology contains many predictions which have failed to come true and many applications that have not been foreseen. While we must (...) reserve judgment as to the question of the impact on the structure of society and human thought, there is no reason to wait for history when it comes to the question: what are the properties that could give the computer such far-reaching importance? The present book is intended as an answer to this question. The fact that this is a theoretical analysis is due to the nature of the subject. No other possibilities are available because such a description of the properties of the computer must be valid for any kind of application. An additional demand is that the description should be capable of providing an account of the properties which permit and limit these possible applications, just as it must make it possible to characterize a computer as distinct from a) other machines whether clocks, steam engines, thermostats, or mechanical and automatic calculating machines, b) other symbolic media whether printed, mechanical, or electronic and c) other symbolic languages whether ordinary languages, spoken or written or formal languages. This triple limitation, however, (with regard to other machines, symbolic media and symbolic languages) raises a theoretical question as it implies a meeting between concepts of mechanical-deterministic systems, which stem from mathematical physics, and concepts of symbolic systems which stem from the description of symbolic activities common to the humanities. The relationship between science and the humanities has traditionally been seen from a dualistic perspective, as a relationship between two clearly separate subject areas, each studied on its own set of premises and using its own methods. In the present case, however, this perspective cannot be maintained since there is both a common subject area and a new - and specific - kind of interaction between physical and symbolic processes.

Stevan Harnad correctly perceives a deep problem in computationalism, the hypothesis that cognition is computation, namely, that the symbols manipulated by a computational entity do not automatically mean anything. Perhaps, he proposes, transducers and neural nets will not have this problem. His analysis goes wrong from the start, because computationalism is not as rigid a set of theories as he thinks. Transducers and neural nets are just two kinds of computational system, among many, and any solution to the semantic problem (...) that works for them will work for most other computational systems.

The concept of ‘digital phenotyping’ was originally developed by researchers in the mental health field, but it has travelled to other disciplines and areas. This commentary draws upon our experiences of working in two scientific projects that are based at the University of Oxford’s Big Data Institute – The RADAR-AD project and The Minerva Initiative – which are developing algorithmic phenotyping technologies. We describe and analyse the concepts of digital biomarkers and computational phenotyping that underlie these projects, explain (...) how they are linked to other research in digital phenotyping and compare and contrast some of their epistemological and ethical implications. In particular, we argue that the phenotyping paradigm in both projects is grounded on an assumption of ‘objectivity’ that is articulated in different ways depending on the role that is given to the computational/digital tools. Using the concept of ‘affordance’, we show how specific functionalities relate to potential uses and social implications of these technologies and argue that it is important to distinguish among them as the concept of digital phenotyping is increasingly being used with a variety of meanings.

As two fundamental modes of communication, analog and digital communication are not only ways of information transmission but also two mental habits in our perception and representation of the perception in the creation of communication sign systems. In a broader sense, analog and digital communication are not only for electronic communication or high technology computer networking communication. Language is featured by both analog and digital communication,especially in the development of the writing system. The development of the (...) writing system from images or icons to alphabets is the development of an analog communication to a digital communication. The creation and development of Chinese pictographs illustrate the trend from low digitization to high digitization. From this perspective, we can say that the creation and development of the writing system is a process of digitization. (shrink)

As two fundamental modes of communication, analog and digital communication are not only ways of information transmission but also two mental habits in our perception and representation of the perception in the creation of communication sign systems. In a broader sense, analog and digital communication are not only for electronic communication or high technology computer networking communication. Language is featured by both analog and digital communication,especially in the development of the writing system. The development of the (...) writing system from images or icons to alphabets is the development of an analog communication to a digital communication. The creation and development of Chinese pictographs illustrate the trend from low digitization to high digitization. From this perspective, we can say that the creation and development of the writing system is a process of digitization. (shrink)

This article argues that the computer game can be a locus of aesthetic form in contemporary culture. The context for understanding this claim is the decline of the artwork as bearer of form in the late 20th century, as this was understood by Adorno. Form is the enigmatic other of instrumental reason that emerges spontaneously in creative works and, in the modern era, is defined as that which makes them captivating and enigmatic yet resistant to analytic understanding. Clarification of the (...) ways in which form is at work in game play is sought from aesthetic theory (Kant), ludology (or theory of games), and the idea of a neo-baroque entertainment culture (Ndalianis). Kant emphasized the role of play in the constitution of imaginary realms associated with aesthetic pleasure. Ludology takes play as an anthropological given differentiated historically by the development of game structures. Neo-baroque theory postulates a labyrinthine, complex and de-centred entertainment culture, largely shaped by computing as a cultural practice. The article synthesizes insights from these perspectives and, drawing on ideas from Adorno and Benjamin, argues that computer games can occupy an oppositional or critical role within contemporary aesthetics and culture. Reflection on the constitutive processes of computer game play discloses a new place for instrumental reason within aesthetic experience, as the dialectic of form and analysis migrates from traditional art materials to digital electronics.

The distinction at the heart of van Gelder’s target article is one between digital computers and dynamical systems. But this distinction conflates two more fundamental distinctions in cognitive science that should be keep apart. When this conflation is undone, it becomes apparent that the “computational hypothesis” (CH) is not as dominant in contemporary cognitive science as van Gelder contends; nor has the “dynamical hypothesis” (DH) been neglected.

The authors attempt to speculatively reconstruct the concept of the “So­viet computer game”. They propose to consider gaming practices associ­ated with computers as a derivative of the accepted ideological guidelines that accompany the Soviet project of machine modernization. Within this framework, the concept of the Soviet computer game appears as an unre­alized historical alternative to the normative game design that has devel­oped in countries with market economies. Despite the industry — or the electronic entertainment market — not having (...) had the time to be properly established in the USSR, there were a number of discursive attitudes re­garding the game as such, and the gaming function of computing devices in particular. Even early Soviet pedagogical theories assumed that “playing like a Soviet” involves performing activities structurally similar to labor, where the player becomes part of production. Later, cybernetic discourse, through game theory, indicated the possibility of formalizing any prag­matic activity as a game model; with the advancement of programming, the pragmatics of digital gaming as a way of educating and solving utili­tarian tasks was developed. Based on the memoir archive of Soviet cyber­netics, and publications in the late-Soviet press, the authors demonstrate that the Soviet computer game was not seen an entertainment product, but a representative model for solving problems in an algorithmic form. Thus, the article is not about specific games that could be called Soviet, but about the logic that guided and set the tone for the interpretation of certain computer-game phenomena in the USSR.

In this presentation we shall discuss the nature of mind vis-a-vis the brain and computers. Such a comparison presumes a general equivalence of brains and computers and models the brain as a huge biological computer, with consciousness added. The uniqueness of Mind in the lines of ancient Indian thought has been accpted as the basic concept in the analysis. Regarding the chief difference between mind and brain, material of the mind is taken to be subtle matter.The brain is (...) made of gross matter and is a part of the physical body. Considering the brain and the computer, the brain is a biological structure made of organic molecules, whereas computer chips are inorganic objects manufactured by etching circuits on the surface of silica chips. Thus the human brain, occupying volume, is a volumetric entity whereas a computer, as electronic circuitry on a silica chip, is an areal entity. This explains the vast processing power andexceptional capabilities of the human brain. (shrink)

There are different ways to present a Presidential Address to the APA; the one I have chosen is simply to report on work that I am doing right now, on work in progress. I am going to present some of my further explorations into the computational model of the mind.\**.
