In this work, we investigated a covert communication method in wireless networks, which is realized by multiantenna full-duplex single relay. In the first stage, the source node sends covert messages to the relay, and the relay uses a single antenna to send interference signals to the adversary node to protect the covert information being transmitted. In the second stage, the relay decodes and forwards the covert information received in the first stage; at the same time, the relay uses zero-forcing beamforming (...) to send interference signals to the warden to ensure covert transmission. The detection error rate, transmission outage probability, maximum effective covert rate, and other performance indicators are derived in two stages, and the total performance of the system is derived and analyzed. Then, the performance indicators are verified and analyzed by simulation. Our analysis shows that the maximum effective covert rate of using the characteristics of multiantenna to interfere with Willie in the second stage is taken as the total covert performance of the system, and the transmission interruption probability is significantly less than that of the first stage, so the corresponding maximum effective concealment efficiency will be greater.

The present paper looks at the intersection of juridical and biopower in the U.S. Supreme Court’s school desegregation cases. These cases generally deploy “equitable relief” as a relay between the juridicially-specified injury of segregation and the biopolitical mandates of integration, allowing broad-based biopolitical remedies for juridically identified problems. This strategy enabled the Courts to negotiate between these forms of power. The analysis here thus suggests the continued relevance of juridical power, and also the limits of Foucault’s own analysis, which suggested (...) that biopower tended to fully colonize juridical power by way of norms.

This study decodes consumers' preference levels using a convolutional neural network in neuromarketing. The classification accuracy in neuromarketing is a critical factor in evaluating the intentions of the consumers. Functional near-infrared spectroscopy is utilized as a neuroimaging modality to measure the cerebral hemodynamic responses. In this study, a specific decoding structure, called CNN-based fNIRS-data analysis, was designed to achieve a high classification accuracy. Compared to other methods, the automated characteristics, constant training of the dataset, and learning efficiency of the proposed (...) method are the main advantages. The experimental procedure required eight healthy participants to view commercial advertisement videos of different durations. The cerebral hemodynamic responses of the participants were measured. To compare the preference classification performances, CNN was utilized to extract the most common features, including the mean, peak, variance, kurtosis, and skewness. Considering three video durations, the average classification accuracies of 15, 30, and 60 s videos were 84.3, 87.9, and 86.4%, respectively. Among them, the classification accuracy of 87.9% for 30 s videos was the highest. The average classification accuracies of three preferences in females and males were 86.2 and 86.3%, respectively, showing no difference in each group. By comparing the classification performances in three different combinations between two groups, male participants were observed to have targeted preferences for commercial advertising, and the classification performance 88.4% between “like” vs. “dislike” out of three categories was the highest. Finally, pairwise classification performance are shown as follows: For female, 86.1%, 87.4%, 85.2%, and for male 85.7, 88.4, 85.1%, respectively. (shrink)

This study aims to decode the hemodynamic responses evoked by multiple sound-categories using functional near-infrared spectroscopy. The six different sounds were given as stimuli. The oxy-hemoglobin concentration changes are measured in both hemispheres of the auditory cortex while 18 healthy subjects listen to 10-s blocks of six sound-categories. Long short-term memory networks were used as a classifier. The classification accuracy was 20.38 ± 4.63% with six class classification. Though LSTM networks’ performance was a little higher than chance levels, it is (...) noteworthy that we could classify the data subject-wise without feature selections. (shrink)

The study deals with ekphraseis on works of art and poses the question as to how far these texts can be a reliable source for the study or even the reconstruction of the artefacts they describe. Based on reception theory and readerresponse criticism, in the paper is proposed that as every text, byzantine ekphraseis on artworks presuppose an audience or readership, i. e. the one the author had in mind and on the basis of which he encoded his message. In (...) order to decode this message and by extension to extract any information about the described works of art we must aim to discover their “intended reader”, and identify his or her “horizon of expectations. This proposal is tested in the study of a well known piece of this kind, Manasses’s description of a mosaic floor with a depiction of Earth. The author’s dialogue with the earlier tradition of ekphraseis, his readership’s “horizon of expectations” combined with historical facts, allow us to suppose that Manasses is describing a composition with Xenia scenes and an asarotos motif created in the early byzantine period and preserved in the Great Palace of Constantinople up to the twelfth century.

The principal goal of the brain-computer interface is to translate brain signals into meaningful commands to control external devices or neuroprostheses to restore lost functions of patients with severe motor disabilities. The invasive recording of brain signals involves numerous health issues. Therefore, BCIs based on non-invasive recording modalities such as electroencephalography are safer and more comfortable for the patients. The BCI requires reconstructing continuous movement parameters such as position or velocity for practical application of neuroprostheses. The BCI studies in continuous (...) decoding have extensively relied on extracting features from the amplitude of brain signals, whereas the brain connectivity features have rarely been explored. This study aims to investigate the feasibility of using phase-based connectivity features in decoding continuous hand movements from EEG signals. To this end, the EEG data were collected from seven healthy subjects performing a 2D center-out hand movement task in four orthogonal directions. The phase-locking value and magnitude-squared coherence are exploited as connectivity features along with multiple linear regression for decoding hand positions. A brute-force search approach is employed to find the best channel pairs for extracting features related to hand movements. The results reveal that the regression models based on PLV and MSC features achieve the average Pearson correlations of 0.43 ± 0.03 and 0.42 ± 0.06, respectively, between predicted and actual trajectories over all subjects. The delta and alpha band features have the most contribution in regression analysis. The results also demonstrate that both PLV and MSC decoding models lead to superior results on our data compared to two recently proposed feature extraction methods solely based on the amplitude or phase of recording signals. This study verifies the ability of PLV and MSC features in the continuous decoding of hand movements with linear regression. Thus, our findings suggest that extracting features based on brain connectivity can improve the accuracy of trajectory decoder BCIs. (shrink)

In Greg Bear’s critically acclaimed science fiction novel Darwin’s Radio, the activation of an endogenous retrovirus (SHEVA), ironically located in a “noncoding region” of the human genome, causes extreme symptoms in women worldwide, including miscarriages. In the United States, a task force is assembled to control the pandemic crisis and to find out how SHEVA operates at the genomic level. However, as the story unfolds, it becomes manifest that SHEVA is too complex to decode in this way and, moreover, that (...) it is not a disease at all. Biologist Kay Lang speculates that SHEVA is triggered by signals from the environment, and that newborn SHEVA children will be a new variation or species of Man. In this essay I analyze Bear’s literary experiment with science along Deleuze and Guattari’s important, but largely overlooked, concepts of State science and nomad science. Bear’s novel gives narrative form to nomad-scientific ideas about life, notably Lynn Margulis’s theory of endosymbiogenesis, which holds that a species’ DNA is an assemblage of many genomes acquired in symbiotic relations. The import of Bear’s informed speculations, I argue, is not crass prediction but a nomadic vision of life as always already different (impure, infected) and in becoming—a counterpoint to the image of the double helix as the bedrock of human identity. Darwin’s Radio is a key example of how fiction can be an excellent partner for science, technology, and society, analyzing and intervening in debates about life and laying bare epistemological and biopolitical tensions of technoscience.

The synthetic, integrative significance of biosemiotics as a modern interdisciplinary research program is under discussion in the article. Aimed at studying the cognitive and life activity of living beings, which are capable of recognizing signals and extracting the meanings, biosemiotics serves as a conceptual node that combines some important notions of theoretical biology, evolutionary epistemology, cognitive science, phenomenology, neuroscience and neurophilosophy as well as the theory of complex adaptive systems and network science. Worlds of perception and actions of living beings (...) are built in the process of co-evolution, in structural coupling and in enactive interaction with the surrounding natural environment (Umwelt). Thereby the biosemiotic theories developed by the founders of biosemiotics (J. von Uexküll, Th. Sebeok, G. Prodi, H. Pattie) are conceptually closed to the system-structural evolutionary approach developed in synergetics by H. Haken and S.P. Kurdyumov, the conception of autopoiesis (H. Maturana and F. Varela), second-order cybernetics (H. von Foerster), the conception of enactivism in cognitive science (F. Varela, E. Thompson, A. Noë). The key to comprehending the processes of extracting and generating meanings is that every living organism lives in the subjectively built world (Umwelt), so that its Umwelt and its internal psychic organization become parts of a single autopoietic system. According to the well-known expression of G. Bateson, information is a not indifferent difference or a difference that makes a difference. Differences become information when a cognitive agent as an interpreter, acting as part of an autopoietic system, sees signs in these differences that make meanings. (shrink)

This book presents a systematic design methodology for decoding the interior structure of the Antikythera mechanism, an astronomical device from ancient Greece. The historical background, surviving evidence and reconstructions of the mechanism are introduced, and the historical development of astronomical achievements and various astronomical instruments are investigated. Pursuing an approach based on the conceptual design of modern mechanisms and bearing in mind the standards of science and technology at the time, all feasible designs of the six lost/incomplete/unclear subsystems are synthesized (...) as illustrated examples, and 48 feasible designs of the complete interior structure are presented. This approach provides not only a logical tool for applying modern mechanical engineering knowledge to the reconstruction of the Antikythera mechanism, but also an innovative research direction for identifying the original structures of the mechanism in the future. In short, the book offers valuable new insights for all readers who are interested in the Antikythera mechanism. (shrink)

Decoding the function and meaning of a foreign culture's sounds and gestures is a notoriously difficult problem. It is even more challenging when we think about the sounds and gestures of nonhuman animals. This essay provides a review of what is currently known about the informational content and function of primate vocalizations, emphasizing the problems underlying the construction of a primate “dictionary.” In contrast to the Oxford English Dictionary, this dictionary provides entries to emotional expressions as well as potentially referential (...) expressions. It therefore represents a guide to what animals do with their vocalizations, as well as how they are represented by signalers and perceivers. I begin by a discussion of the unit problem, of how an acoustic space is carved up into functionally significant components leading to a species‐specific repertoire or lexicon of sorts. This section shows how little we know about the units of organization within animal vocal repertoires, and how such lack of information constrains our ability to tackle the problem of syntactic structure. In Section III, I review research on the production and perception of vocal signals that appear to be functionally referential. This work shows that several nonhuman primates produce vocalizations that share some of the key properties of reference, but certainly not all; the components that are missing raises questions about their role as precursors to human words. In Section IV, I explore the social uses of vocalizations, assessing whether the signal contains sufficient information for listeners to judge a caller's credibility; ultimately, caller credibility determines how receivers select an appropriate response. Results show that individuals can use calls to assess whether someone is reliable or unreliable, and that such attributes are associated with individuals and particular contexts. I conclude by synthesizing the issues presented and then raise some directions for future conceptual and methodological progress. (shrink)

In various documents the view emerges that contemporary biotechnosciences are currently experiencing a scientific revolution: a massive increase of pace, scale and scope. A significant part of the research endeavours involved in this scientific upheaval is devoted to understanding and, if possible, ameliorating humankind: from our genomes up to our bodies and brains. New developments in contemporary technosciences, such as synthetic biology and other genomics and “post-genomics” fields, tend to blur the distinctions between prevention, therapy and enhancement. An important dimension (...) of this development is “biomimesis”: i.e. the tendency of novel technologies and materials to mimic or plagiarize nature on a molecular and microscopic level in order to optimise prospects for the embedding of technological artefacts in natural systems such as human bodies and brains. In this paper, these developments are read and assessed from a psychoanalytical perspective. Three key concepts from psychoanalysis are used to come to terms with what is happening in research laboratories today. After assessing the general profile of the current revolution in this manner, I will focus on a particular case study, a line of research that may serve as exemplification of the vicissitudes of contemporary technosciences, namely viral biomaterials. Viral life forms can be genetically modified (their genomes can be rewritten) in such a manner that they may be inserted in human bodies in order to produce substances at specific sites such as hormones (testosterone), neurotransmitters (dopamine), enzymes (insulin) or bone and muscle tissue. Notably, certain target groups such as top athletes, soldiers or patients suffering from degenerative diseases may become the pioneers serving as research subjects for novel applications. The same technologies can be used for various purposes ranging from therapy up to prevention and enhancement. (shrink)

The author explores how the discursive practices of social texts relate to the subjectivities of readers. Employing Dorothy Smith's notion of femininity as textually mediated discourse, the author analyzes how teenage girls read the depictions of femininity in the glossy advertisements of fashion magazines. Through interviews with 48 girls aged 13 to 17 years, she explores both why and how young girls negotiate “what it means to be a woman.” Most young girls in her study draw on stereotypical meanings of (...) adult femininity. By giving these stereotypes truth status, these readers valorize not only patriarchal meanings of womanhood but also naturalize associations between femininity and the commodities through which this femininity is expressed as the everyday doing of gender. The author concludes by discussing implications of this study for both a feminist theory and a feminist politics of culture. (shrink)

Because Arthur ‘Weegee’ Fellig’s crime scene photographs have become the standard for visually representing crime scenes in popular culture, this paper examines the extra-legal lives of two of his images, both of which were produced at the site of a gangster’s death in 1936. To decode the crime scene photograph is to interrogate the ways in which we make sense of crime through seeing and narrating. To that end, this paper charts how these two crime images were contextualized first in (...) a tabloid narrative that invited viewer identification with the law enforcer, and later in Weegee’s own autobiographical narrative as a hardboiled photographer. In contrast to these human ways of seeing and narrating, the images are then examined through computer vision. By moving across these different ways of human and nonhuman seeing, we are arrested anew by the crime scene photograph as different narrators make clear, often for different audiences, who and what it is that we are looking at. Our visual point of focus, in turn, tells us how we engage with crime images at the mediated intersection of law and popular culture; it reveals how viewers identify with the law as a result of an image’s visual structure, as well as through representational exchanges that blur the edges between fact and fiction.

Interpreting the letters characterized as written by Alice Alington and Margaret Roper in 1534 has proved perplexing since their first publication, when the editor wrote, “It is not certainly known” whether Thomas More or Roper wrote the letter to Alington. Did Roper, More, or both write it? This study looks at both letters from a variety of perspectives, pointing out many reasons that complicate reading them before focusing on the personal and political circumstances, the structural knot of wise/foolish, and the (...) writing styles of father and daughter, including an analysis of Roper's known writing, characteristically empathic. It agrees that More was the chief writer, but that Roper might well have written some, though not all, of her speeches, and that she was involved in their discussions and as More's personal representative. Finally, it suggests both letters constitute a mini-dialogue. (shrink)

The Drake Relays are one of the iconic events of track and field in the United States. World and Olympic champions test their speed and stamina on the famed Blue Oval in Des Moines, Iowa, every April, and by spring 2013 they had set fourteen world records and fifty-one American records. But unlike most other top meets, this one also features college athletes from all over the country and high school athletes from across Iowa, giving them the experience of (...) a lifetime—competing on the same track with the elite in their sport. This mix brings many enthusiastic spectators to the stadium and makes for an unusually close bond between fans and athletes—it’s as if everyone’s family is there cheering. Pulitzer Prize–winning photographer David Peterson has been covering the Drake Relays for nearly forty years, but his love affair with the meet started earlier, when he ran on three winning relay teams there for Kansas State University. Now, drawing upon an unmatched personal archive, he offers the pictures of a lifetime spent on the Blue Oval. He captures on camera athletes of all levels in triumph and defeat, in mid-stride or leap, embracing their fans, their moms and dads, and their kids. In addition to the stars of the past, such as Carl Lewis, Suzy Favor Hamilton, and Herschel Walker, and those of the ’00s, like Lolo Jones and Jeremy Wariner, we see teenagers who may be the stars of the future, as well as the many athletes who will never be famous but nonetheless show themselves—and their sport—at their best. A beautiful celebration of the Drake Relays and the diverse sports that make up “track and field,” this book will evoke memories and inspire runners, throwers, and jumpers everywhere. (shrink)

New brain imaging technology has emerged that might make it possible to read a person's thoughts directly from their brain activity. This novel approach is referred to as “brain reading” or the “decoding of mental states.” This article provides a general outline of the field and discusses its limitations, potential applications, and also certain ethical issues that brain reading raises. The measurement of brain activity and brain structure has made considerable progress in recent decades. The mapping from brain activity patterns (...) to thoughts is learned for each specific subject using brute force statistical pattern recognition techniques. It discusses the degree to which polygraphy and brain-based lie detection can be manipulated by trained subjects. A future application of brain reading technology, “neuromarketing,” has received tremendous interest and there are repeated attempts to optimize marketing campaigns by adding brain-based sources of information.

_A fresh and fascinating look at the philosophies, politics, and intellectual legacy of one of the twentieth century’s most influential and controversial minds_ Occupying a pivotal position in postwar thought, Noam Chomsky is both the founder of modern linguistics and the world’s most prominent political dissident. Chris Knight adopts an anthropologist’s perspective on the twin output of this intellectual giant, acclaimed as much for his denunciations of US foreign policy as for his theories about language and mind. Knight explores the (...) social and institutional context of Chomsky’s thinking, showing how the tension between military funding and his role as linchpin of the political left pressured him to establish a disconnect between science on the one hand and politics on the other, deepening a split between mind and body characteristic of Western philosophy since the Enlightenment. Provocative, fearless, and engaging, this remarkable study explains the enigma of one of the greatest intellectuals of our time. (shrink)

This paper is reporting on electronic implementation of a three-dimensional autonomous system with infinite equilibrium point belonging to a parabola. Performance analysis of an adaptive synchronization via relay coupling and a hybrid steganography chaos encryption application are provided. Besides striking parabolic equilibrium, the proposed three-dimensional autonomous system also exhibits hidden chaotic oscillations as well as hidden chaotic bursting oscillations. Electronic implementation of the hidden chaotic behaviors is done to confirm their physical existence. A good qualitative agreement is shown between numerical (...) simulations and OrCAD-PSpice results. Moreover, adaptive synchronization via relay coupling of three three-dimensional autonomous systems with a parabolic equilibrium is analysed by using time histories. Numerical results demonstrate that global synchronization is achieved between the three units. Finally, chaotic behavior found is exploited to provide a suitable text encryption scheme by hidden secret message inside an image using steganography and chaos encryption. (shrink)

Validity of physical laws for any aspect of brain activity and strict correlation of mental to physical states of the brain do not imply, with logical necessity, that a complete algorithmic theory of the mind-body relation is possible. A limit of decodability may be imposed by the finite number of possible analytical operations which is rooted in the finiteness of the world. It is considered as a fundamental intrinsic limitation of the scientific approach comparable to quantum indeterminacy and the theorems (...) of logical undecidability. An analysis of these limits, applied to dispositions of future behaviour, suggests that limits of decodability of the psycho-physic relation may actually exist with respect to brain states with self-referential aspects, as they are involved in mental processes. Limits for an algorithmic theory of the mind-body problem suggested by this study are formally similar to other intrinsic limits of the scientific method such as quantum indeterminacy and mathematical undecidability which are also related to self-referential operations. At the metatheoretical level, hard sciences, despite their reliability, universality and objectivity, depend on metatheoretical presuppositions which allow for multiple philosophical interpretations. -/- .

The syllogistic mnemonic known by its first two words Barbara Celarent introduced a constellation of terminology still used today. This concatenation of nineteen words in four lines of verse made its stunning and almost unprecedented appearance around the beginning of the thirteenth century, before or during the lifetimes of the logicians William of Sherwood and Peter of Spain, both of whom owe it their lasting places of honor in the history of syllogistic. The mnemonic, including the theory or theories it (...) encoded, was prominent if not dominant in syllogistics for the next 700 years until a new paradigm was established in the 1950s by the great polymath Jan Łukasiewicz, a scholar equally at home in philosophy, classics, mathematics, and logic. Perhaps surprisingly, the then-prominent syllogistic mnemonic played no role in the Łukasiewicz work. His 1950 masterpiece does not even mention the mnemonic or its two earliest champions William and Peter. The syllogistic mnemonic is equally irrelevant to the post-Łukasiewicz paradigm established in the 1970s and 1980s by John Corcoran, Timothy Smiley, Robin Smith, and others. Robin Smith’s comprehensive 1989 treatment of syllogistic does not even quote the mnemonic’s four verses. Smith’s work devotes only 2 of its 262 pages to the mnemonic. The most recent translation of Prior Analytics by Gisela Striker in 2009 continues the post-Łukasiewicz paradigm and accordingly does not quote the mnemonic or even refer to the code—although it does use the terminology. Full mastery of modern understandings of syllogistic does not require and is not facilitated by ability to decode the mnemonic. Nevertheless, an understanding of the history of logic requires detailed mastery of the syllogistic mnemonic, of the logical theories it spawned, and of the conflicting interpretations of it that have been offered over the years by respected logicians such as De Morgan, Jevons, Keynes, and Peirce. More importantly, an understanding of the issues involved in decoding the mnemonic might lead to an enrichment of the current paradigm—an enrichment so profound as to constitute a new paradigm. After presenting useful expository, bibliographic, hermeneutic, historical, and logical background, this paper gives a critical exposition of Smith’s interpretation. (shrink)

As the demand for prosthetic limbs with reliable and multi-functional control increases, recent advances in myoelectric pattern recognition and implanted sensors have proven considerably advantageous. Additionally, sensory feedback from the prosthesis can be achieved via stimulation of the residual nerves, enabling closed-loop control over the prosthesis. However, this stimulation can cause interfering artifacts in the electromyographic (EMG) signals which deteriorate the reliability and function of the prosthesis. Here, we implement two real-time stimulation artifact removal algorithms, Template Subtraction (TS) and ε-Normalized (...) Least Mean Squares (ε-NLMS), and investigate their performance in offline and real-time myoelectric pattern recognition in two transhumeral amputees implanted with nerve cuff and EMG electrodes. We show that both algorithms are capable of significantly improving signal-to-noise ratio (SNR) and offline pattern recognition accuracy of artifact-corrupted EMG signals. Furthermore, both algorithms improved real-time decoding of motor intention during active neurostimulation. Although these outcomes are dependent on the user-specific sensor locations and neurostimulation settings, they nonetheless represent progress toward bi-directional neuromusculoskeletal prostheses capable of multifunction control and simultaneous sensory feedback.

Digital technology has facilitated additional means for human communication, allowing social connections across communities, cultures, and continents. However, little is known about the effect these communication technologies have on the ability to accurately recognize and utilize nonverbal behavior cues. We present two competing theories, which suggest (1) the potential for technology use toenhancenonverbal decoding skill or, (2) the potential for technology use tohindernonverbal decoding skill. We present preliminary results from two studies to test these hypotheses. Study 1 (N= 410) found (...) that global screen time was unrelated to nonverbal decoding skill. However, how participants spent their time using technology mattered. Participants who reported more active technology use (i.e., posting content) self-reported that their nonverbal decoding skill (as measured by the Emotional Sensitivity subscale of the Social Skills Inventory) was superior but performed worse on objective measures of decoding skill (using standardized tests including the Diagnostic Analysis of Nonverbal Accuracy-Adult Faces and the Workplace Interpersonal Perception Skill). By contrast, passive users performed significantly better on objective measures of nonverbal decoding skill; although they did not self-report any difference in their skill compared to less passive users. Study 2 (N= 190), and a mini-meta analysis of both studies, replicated this pattern. These effects suggest a roadmap for understanding the theoretical relationship between technology use and nonverbal communication skills. We also provide recommendations for future research, including the use of experimental designs to determine causal pathways and to advance our conceptual understanding of the relationship between technology use and nonverbal decoding skill.

Diversity is important for the resilience of food systems, as well as for its own sake. Just how diverse are the systems that produce our food? I explore this question with a focus on wheat and bread and North America, and even more specifically in baking, milling and farming. Although the opacity of food and agricultural systems makes definitive answers difficult, these segments appear to be increasingly uniform with respect to ownership, geography, varieties and genes. There are also important countertrends, (...) and while efforts to resist uniformity are currently small, they are making some progress in maintaining or even increasing diversity in some areas.

A brain-computer interface technology that can decode the neural signals associated with attempted but unarticulated speech could offer a future efficient means of communication for people with severe motor impairments. Recent demonstrations have validated this approach. Here we assume that it will be possible in future to decode imagined (i.e., attempted but unarticulated) speech in people with severe motor impairments, and we consider the characteristics that could maximize the social utility of a BCI for communication. As a social interaction, communication (...) involves the needs and goals of both speaker and listener, particularly in contexts that have significant potential consequences. We explore three high-consequence legal situations in which neurally-decoded speech could have implications:Testimony, where decoded speech is used as evidence;Consent and Capacity, where it may be used as a means of agency and participation such as consent to medical treatment; andHarm, where such communications may be networked or may cause harm to others. We then illustrate how design choices might impact the social and legal acceptability of these technologies. (shrink)

‘Information’ and ‘code’ originated as technical terms within linguistics and information theory but are now widely used in genetics and developmental biology. Against this background, it is examined if coded information distinguishes genes from other information carriers, i.e., whether there are genetic words or sentences by virtue of the genetic code, and, if so, whether they have any semantic content. It is concluded that there is no genetic language with semantic content, but that the genetic code still enables unique language-like (...) modes of transmission and interpretation of causal information.

The typical approach to decoding speech from the brain (using brain-machine interfaces) is to decode low-level linguistic units (e.g. phonemes, syllables) from motor articulation areas (e.g. Premotor cortex) with the aim of assembling these low-level units into higher-level discourse. We propose that brain-to-speech decoding may benefit from adopting a functional view of language, which conceives of language as an instrumental tool for interacting with others' intentions in order to fulfil one's own intentions. This functional view of language motivates adopting usability (...) (i.e. the decoder's usefulness as a tool for achieving goals), in addition to decoding accuracy, as a criterion for assessing decoder performance. Decoders may achieve gains in usability by incorporating data about communicative situations and speaker intentions in order to generate and fill in speech act templates. We suggest that this intention-oriented, template-based, and functionally inspired view of brain-to-speech decoding may facilitate efforts to achieve naturalistic speech decoding. (shrink)

Rabbi Moses Cordoeiro was a towering mystical thinker in Safed and retains to this day a seat of honor in Jewish intellectual history. Ranking among the most prolific and lucid thinkers Judaism has ever known, Cordoeiro had an enormous impact on the trajectory of mystical philosophy from the 16th century onward. This book - the first extensive work on Cordoeiro in English sheds new and important light on his life, writings, practical piety, and, most importantly, systematic thought in Kabbalah. By (...) placing Cordoeiro's personal growth and conceptual evolution within sociopolitical and theoretical context, his works are thoroughly investigated with the aim of articulating his elaborate theoretical model and its relations to his mystical practices. Much attention has been given throughout this book to Cordoeiro's acute philological sensitivity, for his view of Hebrew as "God's Vernacular" had prompted him to introduce bold and often remarkably creative exegetical maneuvers. This book is a significant contribution to philosophical scholarship and to anyone interested in exploring the deeper realms of Jewish mystical thought. (shrink)

A Life Decoded is an exhilarating document, to begin with, reading like a novel or even a science epic. In the author’s own words, it is “a tale of seemingly impossible quests and grand objectives”, of “great rivalries and bitter disputes”, of “battles of ideologies, morals and ethics” and of “clashes of egos” (p. 2), an adventure that swept the author “from peaks of incredible exhilaration as I marshaled a relatively small but dedicated army of scientists, computers and robots to (...) achieve what seemed almost impossible, and then plunged me into black pits of depression as I faced opposition from Nobel laureates and senior government officials, my colleagues, and even my wife” (p. 2). Moreover, besides being an autobiography proper, the book also contains a series of reflections on the genes present in the author’s own genome, one of the first individual genomes that was sequenced and made publicly available on the web – the “recipe” that made Craig Venter, as he himself describes it. In separate boxes dedicated to his sequenced genome, he especially focuses on genes that are associated with behavioural characteristics such as thrill-seeking behaviour, ADHD and the ability to cope with almost superhuman amounts of stress. Thus, in Venter’s case, autobiography and the genome are connected in more than one way with one another. (shrink)

The term ‘locked-in’ syndrome (LIS) describes a medical condition in which persons concerned are severely paralyzed and at the same time fully conscious and awake. The resulting anarthria makes it impossible for these patients to naturally communicate, which results in diagnostic as well as serious practical and ethical problems. Therefore, developing alternative, muscle-independent communication means is of prime importance. Such communication means can be realized via brain–computer interfaces (BCIs) circumventing the muscular system by using brain signals associated with preserved cognitive, (...) sensory, and emotional brain functions. Primarily, BCIs based on electrophysiological measures have been developed and applied with remarkable success. Recently, also blood flow–based neuroimaging methods, such as functional magnetic resonance imaging (fMRI) and functional near-infrared spectroscopy (fNIRS), have been explored in this context. After reviewing recent literature on the development of especially hemodynamically based BCIs, we introduce a highly reliable and easy-to-apply communication procedure that enables untrained participants to motor-independently and relatively effortlessly answer multiple-choice questions based on intentionally generated single-trial fMRI signals that can be decoded online. Our technique takes advantage of the participants’ capability to voluntarily influence certain spatio-temporal aspects of the blood oxygenation level–dependent (BOLD) signal: source location (by using different mental tasks), signal onset and offset. We show that healthy participants are capable of hemodynamically encoding at least four distinct information units on a single-trial level without extensive pretraining and with little effort. Moreover, realtime data analysis based on simple multi-filter correlations allows for automated answer decoding with a high accuracy (94.9%) demonstrating the robustness of the presented method..

Brain reading technologies are rapidly being developed in a number of neuroscience fields. These technologies can record, process, and decode neural signals. This has been described as ‘mind reading technology’ in some instances, especially in popular media. Should the public at large, be concerned about this kind of technology? Can it really read minds? Concerns about mind-reading might include the thought that, in having one’s mind open to view, the possibility for free deliberation, and for self-conception, are eroded where one (...) isn’t at liberty to privately mull things over. Themes including privacy, cognitive liberty, and self-conception and expression appear to be areas of vital ethical concern. Overall, this article explores whether brain reading technologies are really mind reading technologies. If they are, ethical ways to deal with them must be developed. If they are not, researchers and technology developers need to find ways to describe them more accurately, in order to dispel unwarranted concerns and address appropriately those that are warranted.

Describing an algorithm can provide a formalization of a specific process. However, different ways of conceptualizing algorithms foreground certain issues while obscuring others. This article attempts to define an algorithm in a broad sense as a cultural activity of key importance to make sense of socio-cognitive structures. It also attempts to develop a sharper account on the interaction between humans and tools, symbols and technologies. Rather than human or machine-centered analyses, I draw upon sociological and anthropological theories that underline social (...) practices to propose expanding our understanding of an algorithm through the notion of ‘collective intentionalities’. To make this term clear, a brief historical review is presented, followed by an argumentation on how to incorporate it in an integral perspective. The article responds to recent debates in critical algorithm studies about the significance of the term. It develops a discussion along the lines of cognitive anthropology and the cognitive sciences, therefore advancing a definition that is grounded in observed practices as well as in modeled descriptions. The benefit of this approach is that it encourages scholars to explore cognitive structures via archaeologies of technological assemblages, where intentionalities play a defining role in understanding socio-structured practices and cognitive ecologies.

The olfactory system was traditionally thought to lack a thalamic relay to mediate top-down influences from memory and attention in other perceptual modalities. Olfactory perception was therefore often described as an outlier among perceptual modalities. It was argued as a result that olfaction was a canonical example of a direct perception. In this paper we review functional and anatomical evidence which demonstrates that olfaction depends on both direct pathway connecting anterior piriform cortex to orbitofrontal cortex and an indirect thalamic circuit (...) connecting posterior piriform cortex and orbitofrontal cortices to the olfactory system. We argue that the indirect corticothalamic circuit has the structure to potentially mediate mediates top-down influences of memory and attention in olfactory perception. This suggests that olfaction is not an outlier after all. (shrink)

Currently, the most used method to measure brain activity under a non-invasive procedure is the electroencephalogram (EEG). This is because of its high temporal resolution, ease of use, and safety. These signals can be used under a Brain Computer Interface (BCI) framework, which can be implemented to provide a new communication channel to people that are unable to speak due to motor disabilities or other neurological diseases. Nevertheless, EEG-based BCI systems have presented challenges to be implemented in real life situations (...) for imagined speech recognition due to the difficulty to interpret EEG signals because of their low signal-to-noise ratio (SNR). As consequence, in order to help the researcher make a wise decision when approaching this problem, we offer a review article that sums the main findings of the most relevant studies on this subject since 2009. This review focuses mainly on the pre-processing, feature extraction, and classification techniques used by several authors, as well as the target vocabulary. Furthermore, we propose ideas that may be useful for future work in order to achieve a practical application of EEG-based BCI systems toward imagined speech decoding. (shrink)

In recent years, neuroscience has begun to transform itself into a “big data” enterprise with the importation of computational and statistical techniques from machine learning and informatics. In addition to their translational applications such as brain-computer interfaces and early diagnosis of neuropathology, these tools promise to advance new solutions to longstanding theoretical quandaries. Here I critically assess whether these promises will pay off, focusing on the application of multivariate pattern analysis (MVPA) to the problem of reverse inference. I argue that (...) MVPA does not inherently provide a new answer to classical worries about reverse inference, and that the method faces pervasive interpretive problems of its own. Further, the epistemic setting of MVPA and other decoding methods contributes to a potentially worrisome shift towards prediction and away from explanation in fundamental neuroscience. (shrink)

Grodzinsky interprets linguistic differences between agrammatic comprehension and production symptoms as supporting the hypothesis that the mechanisms underlying grammatical encoding (sentence formulation) and grammatical decoding (syntactic parsing) are at least partially distinct. This inference is shown to be premature. A range of experimentally established similarities between the encoding and decoding processes is highlighted, testifying to the viability of the hypothesis that receptive and productive syntactic tasks are performed by the same syntactic processor.

The article discusses the methodology for studying reflective systems, which are very specific objects of study. However, such objects include almost all phenomena of the socio-humanitarian sciences, including scientific knowledge. It is noted that in the era of the “sixties” original concepts of reflexive analysis arose in Russian philosophy, among which the three most striking ones, associated with the names of V.A. Lefebvre (1936-2020), G.P. Shchedrovitsky (1929-1994), M.A. Rozova (1930-2011). The main attention is paid to the methodology that was built (...) within the framework of the theory of social relay races by M.A. Rosova. It is shown how systems with reflection function and why they are able to rebuild, changing the order of sociality. (shrink)

In England, current government policy on children's reading is strongly prescriptive, insisting on the delivery of a pure and exclusive form of synthetic phonics, where letter sounds are learned and blended in order to ‘read’ text. A universally imposed phonics ‘check’ is taken by all five year olds and the results are widely reported. These policies are underpinned by the claim that research has shown systematic synthetic phonics to be the most effective way of teaching children to read. Andrew Davis (...) argues that there is a basic problem with this claim. Whatever it is that empirical researchers take themselves to be doing when they investigate synthetic phonics, they are not investigating a specifiable method of teaching reading. This is for two reasons. First, there are no such things as specifiable methods of teaching. Teaching is a vastly complex human activity involving contextual and reactive practical judgments that are responsive to the myriad contingencies of classroom life. The idea that teachers might proceed by way of prescribed methods rather than practical judgments is simply a fantasy. Second, teaching children to correlate letter combinations with sounds, and to blend sounds into sequences, is not teaching them to read. Reading is a matter of grasping meaning conveyed by text. While sustained attention to letter-sound correspondences can be helpful to some novice readers, we should neither assume that it is helpful to all nor confuse mastery of such correspondences with the ability to read. Davis's challenge to government policy on the teaching of reading, and to the empirical research that supposedly underpins it, is timely, radical and compelling. The zeal with which synthetic phonics is championed by its advocates has been remarkably effective in pushing it to the top of the educational agenda; but we should not mistake zeal for warrant.

Humans, like other primates, are intensely social creatures. One of the major functions of our brains must be to enable us to be as skilful in social interactions as we are in our interactions with the physical world. Furthermore, any differences between human brains and those of our nearest relatives, the great apes, are likely to be linked to our unique achievements in social interaction and communication rather than our motor or perceptual skills. Unique to humans is the ability to (...) mentalise, that is to perceive and communicate mental states, such as beliefs and desires. A key problem facing science is to uncover the biological mechanisms underlying our ability to read other minds and to show how these mechanisms evolved. To solve this problem we need to do experiments in which people interact with one another rather than behaving in isolation. Such experiments are now being conducted in increasing numbers and many of the leading exponents of such experiments have contributed to this volume. 'The Neuroscience of Social Interactions' will be an important step in uncovering the biological mechanisms underlying social interactions - undoubtedly one of the major programmes for neuroscience in the 21st century.

The genetic code is a set of instructions that determine how the information in our genetic material is translated into amino acids. In general, it is universal for all organisms, from viruses and bacteria to humans. However, in the last few decades, exceptions to this rule have been identified both in pro‐ and eukaryotes. In this review, we discuss the 16 described alternative eukaryotic nuclear genetic codes and observe theories of their appearance in evolution. We consider possible molecular mechanisms that (...) allow codon reassignment. Most reassignments in nuclear genetic codes are observed for stop codons. Moreover, in several organisms, stop codons can simultaneously encode amino acids and serve as termination signals. In this case, the meaning of the codon is determined by the additional factors besides the triplets. A comprehensive review of various non‐standard coding events in the nuclear genomes provides a new insight into the translation mechanism in eukaryotes. (shrink)

"In thinking about music it is difficult to avoid representing any concrete instance as if it were a stable and essentially pre-formed entity composed of fully determinate and ultimately static objects or relations. Certainly, in the actual performance of music there is no escaping the contingency and indeterminacy that inhere in every temporal act. When we attempt to analyze the musical event, however, it is most convenient to imagine that the intricate web of relationships that comes into play on such (...) an occasion has already been woven in a prior compositional act or in a determinate and determining order of values and beliefs. We can, for example, point to the score as a fixed set of instructions for the recreation of an essentially self-same work or as a repository wherein the traces of a composer's thought lie encoded awaiting faithful decoding by a receptive performer/listener. Or, with even greater abstraction, we can point to the presence of an underlying tonal system, the governing rules of a style or "common practice," the reflection of a set of existing social relations, or the role of hardened ideologies in music's production and reception. It must be said that there is some truth in the variety of determinacies that intellectual analysis would ascribe to music (if little truth in the claims of any one perspective to speak for the whole). But it must also be said that, to the extent the abstractions of analysis deny or suppress the creativity, spontaneity, and novelty of actual musical experience, analysis will have misrepresented music's inescapably temporal nature. The challenge of taking this temporal nature into account lies in finding ways of speaking of music's very evanescence and thus of developing concepts that would capture both the determinacy and the indeterminacy of events in passage. Stated in this way, such an enterprise appears to be loaded with paradox. However, much of the paradox disappears if we can shift our attention from objects or products to process and from static being to dynamic becoming. Indeed, such a shift might provide a perspective from which the great variety of determinacies we ascribe to music could be seen as inseparable components of musical communication. ". (shrink)

Documentary as Exorcism is an interdisciplinary study that builds upon the insights of postcolonial studies, critical race theory, theological and religious studies and media and film studies to showcase the role of documentary film as a system of signifying capable of registering complex theological ideas while pursuing the authentic aims of documentary filmmaking. Robert Beckford marries the concepts of ‘theology as visual practice' and ‘theology as political engagement' to develop a new mode of documentary filmmaking that embeds emancipation from oppression (...) in its aesthetic. In various documentaries made for Channel 4 and the BBC, Beckford narrates the complicit relationship of Christianity with European expansion, slavery, and colonialism as a historic manifestation of evil. In light of the cannibalistic practices of colonialism that devoured black life, and the church's role in the subjugation and theological legitimation of black bodies, Beckford characterises this form of historic Christian faith as ‘colonial Christianity' and its malevolent or ‘occult' practices as a form of ‘bewitchment' that must be ‘exorcised'. He identifies and exorcises the evil practices of colonialism and their present impact upon African Caribbean Christian communities in Britain in films such as Britain's Slave Trade and Empire Pays Back through a deliberate process of encoding/decoding. The emancipatory impact of this form of documentary filmmaking is demonstrated by its ability to bring issues such as reparations to the public square for debate, and its capacity to change a corporation's trade policies for the good of Africans.
