Bainbridge’s well known “Ironies of Automation” Analysis, design and evaluation of man–machine systems. Elsevier, Amsterdam, pp 129–135, 1983. https://doi.org/10.1016/B978-0-08-029348-6.50026-9) laid out a set of fundamental criticisms surrounding the promises of automation that, even 30 years later, remain both relevant and, in many cases, intractable. Similarly, a set of ironies in technologies for sensor driven self-quantification is laid out here, spanning from instrumental problems in human factors design to much broader social problems. As with automation, these ironies stand in the way (...) of many of the promised benefits of these wearable technologies. It is argued here that without addressing these ironies now, the promises of wearables may not come to fruition, and instead users may experience outcomes that are opposite to those which the designers seek to afford, or, at the very least, those which consumers believe they are being offered. This paper describes four key ironies of sensor driven self-quantification: know more, know better versus no more, no better; greater self-control versus greater social control; well-being versus never being well enough; more choice versus erosion of choice.

Revisiting African philosophy’s classic questions, D. A. Masolo advances understandings of what it means to be human—whether of African or other origin. Masolo reframes indigenous knowledge as diversity: How are we to understand the place and structure of consciousness? How does the everyday color the world we know? Where are the boundaries between self and other, universal and particular, and individual and community? From here, he takes a dramatic turn toward Africa’s current political situation and considers why individual rights and (...) freedoms have not been recognized, respected, demanded, or enforced. Masolo offers solutions for containing socially destructive conduct and antisocial tendencies by engaging community. His unique thinking about community and the role of the individual extends African philosophy in new, global directions. (shrink)

In debates about criteria for human death, several camps have emerged, the main two focusing on either loss of the "organism as a whole" (the mainstream view) or loss of consciousness or "personhood." Controversies also rage over the proper definition of "irreversible" in criteria for death. The situation is reminiscent of the proverbial blind men palpating an elephant; each describes the creature according to the part he can touch. Similarly, each camp grasps some aspect of the complex reality of death. (...) The personhood camp, in contrast to the mainstream "organism" camp, recognizes that a human organism can still be a biological living whole even without brain function. The mainstream camp, in contrast to the personhood camp, recognizes that a person can be permanently, even irreversibly unconscious, and still be a living person so long as his/her body is alive. The author proposes that hylomorphic dualism incorporates both these key insights. But to complete the picture of the entire "death elephant," a fundamental paradigm shift is needed to make sense of other seemingly conflicting insights. The author proposes a "semantic bisection" of the concept of death, analogous to the traditional distinction at the beginning of life between "conception" and "birth." To avoid the semantic baggage associated with the term "death," the two new death-related concepts are referred to as "passing away" (or "deceased") and "deanimation," corresponding, respectively, to sociolegal ceasing-to-be (mirror image of birth) and ontological/theological ceasing-to-be of the bodily organism (mirror image of conception). Regarding criteria, the distinguishing feature is whether the cessation of function is permanent (passing away) or irreversible (deanimation). If the "dead donor rule" were renamed the "deceased donor rule" (both acronyms felicitously being "DDR"), the ethics of organ transplantation from non–heart-beating donors could, in principle, be validly governed by the DDR, even though the donors are not yet ontologically "deanimated." Thus, the paradigm shift satisfies both those who insist on maintaining the DDR and those who claim that it has all along been receiving only lip service and should be explicitly loosened to include those who are "as good as dead." Even so, a number of practical caveats remain to be worked out for non–heart-beating protocols. (shrink)

Lexical Semantics is about the meaning of words. Although obviously a central concern of linguistics, the semantic behaviour of words has been unduly neglected in the current literature, which has tended to emphasize sentential semantics and its relation to formal systems of logic. In this textbook D. A. Cruse establishes in a principled and disciplined way the descriptive and generalizable facts about lexical relations that any formal theory of semantics will have to encompass. Among the topics covered in depth are (...) idiomaticity, lexical ambiguity, synonymy, hierarchical relations such as hyponymy and meronymy, and various types of oppositeness. Syntagmatic relations are also treated in some detail. The discussions are richly illustrated by examples drawn almost entirely from English. Although a familiarity with traditional grammar is assumed, readers with no technical linguistic background will find the exposition always accessible. All readers with an interest in semantics will find in this original text not only essential background but a stimulating new perspective on the field. (shrink)

A three-valued propositional logic is presented, within which the three values are read as ?true?, ?false? and ?nonsense?. A three-valued extended functional calculus, unrestricted by the theory of types, is then developed. Within the latter system, Bochvar analyzes the Russell paradox and the Grelling-Weyl paradox, formally demonstrating the meaninglessness of both.

In some languages every statement must contain a specification of the type of evidence on which it is based: for example, whether the speaker saw it, or heard it, or inferred it from indirect evidence, or learnt it from someone else. This grammatical reference to information source is called 'evidentiality', and is one of the least described grammatical categories. Evidentiality systems differ in how complex they are: some distinguish just two terms (eyewitness and noneyewitness, or reported and everything else), while (...) others have six or even more terms. Evidentiality is a category in its own right, and not a subcategory of epistemic or some other modality, nor of tense-aspect. Every language has some way of referring to the source of information, but not every language has grammatical evidentiality. In English expressions such as I guess, they say, I hear that, the alleged are not obligatory and do not constitute a grammatical system. Similar expressions in other languages may provide historical sources for evidentials. True evidentials, by contrast, form a grammatical system. In the North Arawak language Tariana an expression such as "the dog bit the man" must be augmented by a grammatical suffix indicating whether the event was seen, or heard, or assumed, or reported. This book provides the first exhaustive cross-linguistic typological study of how languages deal with the marking of information source. Examples are drawn from over 500 languages from all over the world, several of them based on the author's original fieldwork. Professor Aikhenvald also considers the role evidentiality plays in human cognition, and the ways in which evidentiality influences human perception of the world.. This is an important book on an intriguing subject. It will interest anthropologists, cognitive psychologists and philosophers, as well as linguists. (shrink)

This paper presents a new formal model for D–N explanation that gives intuitive criteria of acceptability, avoids the known trivializations, and links explanation with confirmation theory. Although set in the twenty-five year tradition of attempts to formalize D–N explanation, it proposes a new direction for the model that is to be distinguished from the syntactical and informational approaches by its introduction of restrictions which derive from the use which the D–N model can have in hypothesis testing. This model, illustrating the (...) verificational approach, revises the classic H–O requirements and amends the notion of partial self-explanation to meet a criticism to which the H–O notion is vulnerable.

Advances in technology are bringing greater insight into the mind, raising a host of privacy concerns. However, the basic psychological mechanisms underlying the perception of privacy violations are poorly understood. Here, we explore the relation between the perception of privacy violations and access to information related to one’s “self.” In two studies using demographically diverse samples, we find that privacy violations resulting from various monitoring technologies are mediated by the extent to which the monitoring is thought to provide access to (...) self-relevant information, and generally neuromonitoring did not rate among the more invasive monitoring types. However, brain monitoring was judged to be more of a privacy violation when described as providing access to self-relevant information than when no such access was possible, and control participants did not judge the invasiveness of neuromonitoring any differently than those told it provided no access to self-relevant information.

Objections to the use of assistive technologies in elite sports are generally raised when the technology in question is perceived to afford the user a potentially “unfair advantage,” when it is perceived as a threat to the purity of the sport, and/or when it is perceived as a precursor to a slippery slope toward undesirable changes in the sport. These objections rely on being able to quantify standards of “normal” within a sport so that changes attributed to the use of (...) assistive technology can be judged as causing a significant deviation from some baseline standard. This holds athletes using assistive technologies accountable to standards that restrict their opportunities to achieve greatness, while athletes who do not use assistive technologies are able to push beyond the boundaries of these standards without moral scrutiny. This paper explores how constructions of fairness and “normality” impact athletes who use assistive technology to compete in a sporting venue traditionally populated with “able-bodied” competitors. It argues that the dynamic and obfuscated construction of “normal” standards in elite sports should move away from using body performance as the measuring stick of “normal,” toward alternate forms of constructing norms such as defining, quantifying, and regulating the mechanical actions that constitute the critical components of a sport. Though framed within the context of elite sports, this paper can be interpreted more broadly to consider problems with defining “normal” bodies in a society in which technologies are constantly changing our abilities and expectations of what normal means.

Physicians have developed a number of implicit and explicit approaches to complex medical decisions. Decision analysis is an explicit, quantitative method of clinical decision making that involves the separation of the probabilities of events from their relative values, or utilities. Its use can help physicians make difficult choices in a manner that promotes true patient participation. Decision analysis also provides a framework for the incorporation of data from multiple sources and for the assessment of the impact of uncertain data on (...) the final decision. Although this approach is imperfect, it represents a significant advance in clinical decision making. (shrink)

Traditional explanations of multistable visual phenomena (e.g. ambiguous figures, perceptual rivalry) suggest that the basis for spontaneous reversals in perception lies in antagonistic connectivity within the visual system. In this review, we suggest an alternative, albeit speculative. explanation for visual multistability - that spontaneous alternations reflect responses to active, programmed events initiated by brain areas that integrate sensory and non-sensory information to coordinate a diversity of behaviors. Much evidence suggests that perceptual reversals are themselves more closely related to the expression (...) of a behavior than to passive sensory responses: (1) they are initiated spontaneously, often voluntarily, and are influenced by subjective variables such as attention and mood; (2) the alternation process is greatly facilitated with practice and compromised by lesions in non- visual cortical areas; (3) the alternation process has temporal dynamics similar to those of spontaneously initiated behaviors; (4) functional imaging reveals that brain areas associated with a variety of cognitive behaviors are specifically activated when vision becomes unstable. In this scheme, reorganizations of activity throughout the visual cortex, concurrent with perceptual reversals, are initiated by higher, largely non- sensory brain centers. Such direct intervention In the processing of the sensory input by brain structures associated with planning and motor programming might serve an important role in perceptual organization, particularly in aspects related to selective attention.
