The current paper details a restricted semantics for active logic, a time-sensitive, contradictiontolerant logical reasoning formalism. Central to active logic are special rules controlling the inheritance of beliefs in general, and beliefs about the current time in particular, very tight controls on what can be derived from direct contradictions (P &¬P ), and mechanisms allowing an agent to represent and reason about its own beliefs and past reasoning. Using these ideas, we introduce a new definition of model and of logical (...) consequence, as well as a new definition of soundness such that, when reasoning with consistent premises, all classically sound rules are sound for active logic. However, not everything that is classically sound remains sound in our sense, for by classical definitions, all rules with contradictory premises are vacuously sound, whereas in active logic not everything follows from a contradiction.

Real world problem-solving (RWPS) is what we do every day. It requires flexibility, resilience, resourcefulness, and a certain degree of creativity. A crucial feature of RWPS is that it involves continuous interaction with the environment during the problem-solving process. In this process, the environment can be seen as not only a source of inspiration for new ideas but also as a tool to facilitate creative thinking. The cognitive neuroscience literature in creativity and problem-solving is extensive, but it has (...) largely focused on neural networks that are active when subjects are not focused on the outside world, i.e., not using their environment. In this paper, I attempt to combine the relevant literature on creativity and problem-solving with the scattered and nascent work in perceptually-driven learning from the environment. I present my synthesis as a potential new theory for real world problem-solving and map out its hypothesized neural basis. I outline some testable predictions made by the model and provide some considerations and ideas for experimental paradigms that could be used to evaluate the model more thoroughly. (shrink)

concepts typically are defined in terms of lacking physical or perceptual referents. We argue instead that they are not devoid of perceptual information because knowledge of real-world situations is an important component of learning and using many abstract concepts. Although the relationship between perceptual information and abstract concepts is less straightforward than for concrete concepts, situation-based perceptual knowledge is part of many abstract concepts. In Experiment 1, participants made lexical decisions to abstract words that were preceded by related (...) and unrelated pictures of situations. For example, share was preceded by a picture of two girls sharing a cob of corn. When pictures were presented for 500 ms, latencies did not differ. However, when pictures were presented for 1,000 ms, decision latencies were significantly shorter for abstract words preceded by related versus unrelated pictures. Because the abstract concepts corresponded to the pictured situation as a whole, rather than a single concrete object or entity, the necessary relational processing takes time. In Experiment 2, on each trial, an abstract word was presented for 250 ms, immediately followed by a picture. Participants indicated whether or not the picture showed a normal situation. Decision latencies were significantly shorter for pictures preceded by related versus unrelated abstract words. Our experiments provide evidence that knowledge of events and situations is important for learning and using at least some types of abstract concepts. That is, abstract concepts are grounded in situations, but in a more complex manner than for concrete concepts. Although people's understanding of abstract concepts certainly includes knowledge gained from language describing situations and events for which those concepts are relevant, sensory and motor information experienced during real-life events is important as well.

Provocative essays on real-world ethical questions from the world's most influential philosopher Peter Singer is often described as the world's most influential philosopher. He is also one of its most controversial. The author of important books such as Animal Liberation, Practical Ethics, Rethinking Life and Death, and The Life You Can Save, he helped launch the animal rights and effective altruism movements and contributed to the development of bioethics. Now, in Ethics in the Real (...) class='Hi'>World, Singer shows that he is also a master at dissecting important current events in a few hundred words. In this book of brief essays, he applies his controversial ways of thinking to issues like climate change, extreme poverty, animals, abortion, euthanasia, human genetic selection, sports doping, the sale of kidneys, the ethics of high-priced art, and ways of increasing happiness. Singer asks whether chimpanzees are people, smoking should be outlawed, or consensual sex between adult siblings should be decriminalized, and he reiterates his case against the idea that all human life is sacred, applying his arguments to some recent cases in the news. In addition, he explores, in an easily accessible form, some of the deepest philosophical questions, such as whether anything really matters and what is the value of the pale blue dot that is our planet. The collection also includes some more personal reflections, like Singer’s thoughts on one of his favorite activities, surfing, and an unusual suggestion for starting a family conversation over a holiday feast. Now with a new afterword by the author, this provocative and original book will challenge—and possibly change—your beliefs about many real-world ethical questions. (shrink)

Despite an abundance of academic conferences, clinical ethicists lacked a forum to share innovative practices with peers and to generate solutions to common challenges. Organizers of the first Clinical Ethics Un-Conference developed a working event centered on active participation and problem solving through peer learning, with the goal of improving realworld practice. Registrants included 95 individuals from 64 institutions. Attendees were surveyed immediately after the Un-Conference, and again eight months later. After eight months, 85 percent (n = 33/39) of the (...) survey respondents reported that they found the event “highly impactful” or “some-what impactful” to their clinical practice, and 23 attendees reported that they had implemented ideas or projects inspired by the event. Three sets of best practice guidelines and four white papers were published from the event. As the field of clinical ethics continues to advance and evolve, this working event format offers an innovative, disruptive alternative to a traditional conference format and may serve as a model for future efforts aimed at improving real-world clinical ethics practice.

Narrative and the real world are not mutually exclusive. Life is not a structureless sequence of events; it consists of complex structures of temporal configurations that interlock and receive their meaning from within action itself. It is also not true that life lacks a point of view which transforms events into a story by telling them. Our focus of attention is not the past but the future, because we grasp configurations extending into the future. Action involves the adoption (...) of an anticipated future-retrospective point of view on the present. The actions of life can be viewed as the process of telling ourselves stories. The retrospective view of the narrator is an extension and refinement of a viewpoint inherent in action itself. Because storytelling is a social activity, the story of one's life is told as much to others as to oneself. Social human time, like individual human time, is constructed into configured sequences. The practical first-order narrative process that constitutes a person or a community can become a second-order narrative whose subject is unchanged but whose interest is primarily cognitive or aesthetic.

Does the real world, defined as a world of objects that exist independent of human interests, concerns, and cognitive activities, really exist? Jan Westerhoff argues that we have good reason to believe it does not. His discussion considers four main facets of the idea of the real world, ranging from the existence of a separate external and internal world, to the existence of an ontological foundation that grounds the existence of all the entities in (...) the world, and the existence of an ultimately true theory that provides a final account of all there is. As Westerhoff discusses the reasons for rejecting the postulation of an external world behind our representations, he asserts that the internal world is not as epistemically transparent as is usually assumed, and that there are good reasons for adopting an anti-foundational account of ontological dependence. Drawing on conclusions from the ancient Indian philosophical system of Madhyamaka Buddhism, Westerhoff defends his stance in a purely Western philosophical framework, and affirms that ontology, and philosophy more generally, need not be conceived as providing an ultimately true theory of the world.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Virtue Ethics for the Real World: Improving Character without Idealization by Howard J. CurzerBenjamin HoleCURZER, Howard J. Virtue Ethics for the Real World: Improving Character without Idealization. New York: Routledge, 2023. 272 pp. Cloth, $160.00The development of virtue ethics has been in a lull. This book is a welcome treatise in theory-building, developing a novel Aristotelian approach to virtue ethics that, first, avoids idealization (...) and, second, provides a method for character improvement. It is divided into two parts reflecting these themes.The front matter before the title page brandishes a "No Don Quixotes" sign, warning the reader the following pages are no place for a misguided idealist. Part 1, "Against Idealization," contains six chapters. Chapter 2 argues that idealization is not a useful guide, but an impediment to virtue, since ideals can be misleading, psychologically damaging, and used for nefarious purposes. Chapters 3 through 7 construct a virtue ethical theory without idealization. Idealization may seem central to a virtue-oriented approach to ethics. For example, Rosalind Hursthouse's famous biconditional claims that an act is right if and only if it is what the virtuous person would characteristically do in the same circumstances. By contrast, chapter 3 provides counterexamples separating virtuous action from what the virtuous person would characteristically do, and separating virtuous action from right action. Sacrificing Hursthouse's biconditional is a fundamental change to the way many conceive of Aristotelian virtue ethics, demanding revisions to the rest of the theory. For instance, to address moral dilemmas, chapter 4 defends two psychological mechanisms under which there are virtuous, morally wrong acts that are admirably immoral, and vicious, morally right acts that leave the agent with dirty hands.Chapter 5 provides the grounding for contemporary Aristotelian virtue ethics without idealization, by answering what makes character traits [End Page 541] virtues and what makes acts virtuous. Two-level eudaimonism involves a thin theory, where virtue consists in responding well to different spheres of human activity, and a thick theory, where responding well contributes to the agent's eudaimonia. Since virtuous people may characteristically perform nonvirtuous actions, virtuous actions are not necessarily what virtuous people characteristically do but actions that are endorsed by virtuous people from the perspective of virtue. The "Perspectives Doctrine" claims that virtuous people decide how to respond from the perspective of different virtues, and those perspectives offer incomplete and sometimes incompatible ways of responding. For instance, a temperate person endorsing an action as temperate from the perspective of temperance makes it temperate, but would not make it courageous, and an endorsement from the perspective of courage would not make her action temperate. Agents determine what is virtuous by asking virtuous people to consider, from the perspective of virtue, what should be done; when virtuous people are unavailable, agents can consult philosophers and social scientists who research the responses of virtuous people. Chapter 6 rejects the "Reciprocity of the Virtue Doctrine," which claims possessing one virtue entails possessing the rest, in favor of the "Unevenly Virtuous People Doctrine," on which people can have some but not all of the virtues; character typically improves at different paces in different areas of life. Chapter 7 rejects Philippa Foot's "Corrective Doctrine" of virtue as implausible idealization in favor of a traditionally Aristotelian "Doctrine of the Mean," and argues that the virtues of integrity, forgiveness, tolerance, open-mindedness, and civility are governed by that doctrine.Although character improvement seems to depend on idealization, by striving to achieve some end, part 2's five chapters paint an alternative picture. Chapter 8 defends a medical analogy over competing models philosophers typically employ to understand character improvement, including skill (Aristotle and Julia Annas), stage or path (Aristotle and Wouter Sanderse), self-cultivation (Mengzi), and self-construction (Xunzi) analogies. To improve character, one must look to a fine-grained list of possible character flaws, diagnose deficits in character, and then heal character flaws by employing targeted strategies, including "inculcation strategies, rehabilitation strategies, and strategies to improve society's ethical climate." Character improvement is complex and becomes more so when considering all of the ways one might err. Chapter 9 introduces an Aristotelian model for moral decision-making within each... (shrink)

In October 2011, the “2nd European Network for Cognitive Systems, Robotics and Interaction”, EUCogII, held its meeting in Groningen on “Autonomous activity in real-world environments”, organized by Tjeerd Andringa and myself. This is a brief personal report on why we thought autonomy in real-world environments is central for cognitive systems research and what I think I learned about it. --- The theses that crystallized are that a) autonomy is a relative property and a matter of (...) degree, b) increasing autonomy of an artificial system from its makers and users is a necessary feature of increasingly intelligent systems that can deal with the real-world and c) more such autonomy means less control but at the same time improved interaction with the system.

In real life, behavior is influenced by dynamically changing contextual factors and is rarely limited to simple tasks and binary choices. For a meaningful interpretation of brain dynamics underlying more natural cognitive processing in active humans, ecologically valid test scenarios are essential. To understand whether brain dynamics in restricted artificial lab settings reflect the neural activity in complex natural environments, we systematically tested the auditory event-related P300 in both settings. We developed an integrative approach comprising an initial P300-study (...) in a highly controlled laboratory set-up and a subsequent validation within a realistic driving scenario. Using a simulated dialog with a speech-based input system, increased P300 amplitudes reflected processing of infrequent and incorrect auditory feedback events in both the laboratory setting and the real world setup. Environmental noise and movement-related activity in the car driving scenario led to higher data rejection rates but revealed comparable theta and alpha frequency band pattern. Our results demonstrate the possibility to investigate cognitive functions like context updating in highly adverse driving scenarios and encourage the consideration of more realistic task settings in prospective brain imaging approaches.

In the present book, Pauline Phemister argues against traditional Anglo-American interpretations of Leibniz as an idealist who conceives ultimate reality as a plurality of mind-like immaterial beings and for whom physical bodies are ultimately unreal and our perceptions of them illusory. Re-reading the texts without the prior assumption of idealism allows the more material aspects of Leibniz's metaphysics to emerge. Leibniz is found to advance a synthesis of idealism and materialism. His ontology posits indivisible, living, animal-like corporeal substances as the (...) real metaphysical constituents of the universe; his epistemology combines sense-experience and reason; and his ethics fuses confused perceptions and insensible appetites with distinct perceptions and rational choice. In the light of his sustained commitment to the reality of bodies, Phemister re-examines his dynamics, the doctrine of pre-established harmony and his views on freedom. The image of Leibniz as a rationalist philosopher who values activity and reason over passivity and sense-experience is replaced by the one of a philosopher who recognises that, in the created world, there can only be activity if there is also passivity; minds, souls and forms if there is also matter; good if there is evil; perfection if there is imperfection.

In this essay the Co-chair of Ethics Working Group 17 of the Health Care Task Force discusses the formation, organization processes and activities of the group, and provides an analysis and critique of the experience. It is suggested that the creation of the group and its inclusion in the process made a social statement which legitimized ethics as a significant part of public policy deliberations. At the same time, major questions are raised about the role of ethics in public policy (...) arenas in which strategic compromise becomes the order of the day. Balanced and objective involvement may be illusory. Ethics, like informed consent, is a process, not an event and is ever evolving. Those who attempt to bring ethical considerations to the world of public policy have an obligation to think carefully about what should constitute an appropriate theoretical framework, make efforts to determine what is unique about ethics, and consider mechanisms for the various ethics disciplines to work effectively together. From this experience, the author developed a personal commitment to focus upon the critical importance of universal coverage for all Americans.

Students often have difficulty connecting theoretical and text-based scholarship to the real world. When teaching in Asia, this disconnection is exacerbated by the European/American focus of many canonical texts, whereas students' own experiences are primarily Asian. However, in my discipline of political philosophy, this problem receives little recognition nor is it comprehensively addressed. In this paper, I propose that the problem must be taken seriously, and I share my own experiences with a novel pedagogical strategy which might offer (...) a possible path forward. Recent scholarship has championed an active learning approach, where students engage in their own research, and deliver outward-facing products that have a meaning and purpose beyond the confines of the student-professor relationship. In this spirit, I have put into practice a strategy of course design, where active learning is used to overcome students' disconnection with the course content. In particular, as a major component of course assessment, students are required to write an 'opinion piece', which is then showcased on a public website. The opinion piece must address a real-world issue which the student himself or herself selects and deems important; furthermore, it must build on the theoretical tools of the course and be written in a style which makes it accessible to a wider audience. I discuss the implementation of this strategy in two political philosophy courses, including strategies to avoid 'dumbing down' and ‘diluting’ the process of critical thinking. While no formal analysis of impact of the strategy on learning outcomes has been conducted, an anonymous pedagogical survey has yielded an overwhelmingly positive response for students' self-reported perceptions of the curricular innovations.

In what sense can aesthetic experience be considered an opportunity for the development of personal identity, cognitive abilities, and emotions? Theatre proves to be an important field of investigation to approach this question. During a theatrical experience, the connection between fiction and reality can take the form of active cooperation between author, actor, and spectator. A better understanding of this point can be drawn by pointing out three kinds of spectator: we can distinguish a critical spectator, an emotional spectator, and (...) an instinctual spectator, who respectively represent: the imaginative and hermeneutic attitude; empathy and fictional emotions; the unconscious satisfaction of drives. So far, a parallel can be established between literature and theatre. However, these two aesthetic experiences are profoundly different: the type of immersion provided by the theatrical experience differs from reading, because the presence of the characters is physical and actual. The pragmatic theatrical framework is the same as that which underlies childhood games. This means that the public too is to some extent called to play, i.e. to act. To appreciate the implications of this thesis, a preliminary analysis of the performance Reality (Deflorian and Tagliarini 2012) is offered, examining how its experience contributes to the development of the spectating subject.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Leibniz and the Natural World: Activity, Passivity, and Corporeal Substances in Leibniz’s PhilosophyMichael FutchPauline Phemister. Leibniz and the Natural World: Activity, Passivity, and Corporeal Substances in Leibniz’s Philosophy. New Synthese Historical Library, 58. Dordrecht: Springer, 2005. Pp. xiii + 293. Cloth, $149.00.Leibniz's metaphysics has long been viewed as one of the more noteworthy systems of idealism in early modern philosophy. At the ground-floor level (...) of his austere ontology, the standard view maintains that the world is not populated by bodies in space and time, but rather by immaterial, mind-like entities: monads. All the rest is a kind of ontological construction from these simple substances. In this book, Pauline Phemister seeks to overturn the idealist reading of Leibniz and to show that "the true immaterial substances in Leibniz's philosophy" are "monads that exist as animated corporeal creatures" (76). What is ontologically basic for Leibniz are not immaterial monads but "living corporeal substances" with "both mental and physical characteristics" (3).If Phemister is right, one wonders what to make of Leibniz's many endorsements of idealism, as, for instance, when he says that "the explanation of all phenomena solely through the perception of monads... with corporeal substances to be rejected, [is] useful for a fundamental investigation of things" (Leibniz to Bartholomew Des Bosses, June [End Page 162] 16, 1712). This programmatic summary is only one of numerous statements from the late period where Leibniz asserts that ultimate reality is composed of immaterial monads. One possible option would be to posit an indecisive vacillation in Leibniz's late philosophy. Rejecting this, Phemister's strategy for dealing with texts such as these—including the "New System," the "Principles of Nature and Grace," and the "Monadology"—is to dismiss them as the rhetorical subterfuge of a Leibniz who is only exoterically, not privately, a Cartesian (15, 163). Leibniz is a public Cartesian in that he "invites comparison of his rational monads with Cartesian minds" by suggesting that the former, like Cartesian minds, are immaterial and incorporeal (13). This is ostensibly only a ruse Leibniz used to ingratiate himself to a Cartesian audience, hiding from them his real view that genuine substances are always corporeal. We are not told why Leibniz would have expected an idealist philosophy that explains mind-body interaction in terms of a pre-established harmony to be well received by Cartesians, but with this hermeneutical principle in hand, Phemister has deftly insulated her criticism from textual refutation.A more pressing concern is Phemister's principle thesis that "the monad is a corporeal substance" (73). Phemister argues that monads are not complete substances unless they comprise not only a soul-like entelechy, but also primary and secondary matter: a monad is not substantially complete "without the subordinate monads that comprise its organic body" (41). What is important to note in this account is that for monads to be complete substances, they must consist of both a "soul-like aspect" and secondary matter, an organic body (133). This organic body is itself an aggregate of other corporeal substances, which are themselves combinations of entelechies and primary and secondary matter (81). The clear consequence of this is that the monad's existence as a complete substance is dependent upon the existence of other substances, namely, those substances that aggregate to form its organic body, the secondary matter that completes the monad as substance. Hence, the existence of complete substances—the only genuine substances—is ontologically derivative. This conclusion flatly contradicts Leibniz's repeated assertions that substances are ontologically basic, not depending for their existence on the existence of other substances, the very cornerstone of Leibniz's metaphysics.This account is also beset by a vicious circularity. For there to be complete substances, there must first be secondary matter, as secondary matter is a constituent of complete substances. As Phemister puts it, "both primary and secondary matter complete the dominant entelechy," making it a genuine substance (71). Without secondary matter, the dominant entelechy does not exist as a substance. But the existence of secondary matter is itself dependent upon the existence of complete substances, for secondary matter just is an aggregate of corporeal substances (84... (shrink)

Pulmonary rehabilitation has demonstrated patients’ physiological and psychosocial improvements, symptoms reduction and health-economic benefits whilst enhances the ability of the whole family to adjust to illness. However, PR remains highly inaccessible due to lack of awareness of its benefits, poor referral and availability mostly in hospitals. Novel models of PR delivery are needed to enhance its implementation while maintaining cost-efficiency. We aim to implement an innovative community-based PR programme and assess its cost-benefit. A 12-week community-based PR will be implemented in (...) primary healthcare centres where programmes are not available. Healthcare professionals will be trained. 73 patients with CRD and their caregivers will compose the experimental group. The control group will include dyads age- and disease-matched willing to collaborate in data collection but not in PR. Patients/family-centred outcomes will be dyspnoea, fatigue, cough and sputum, impact of the disease, emotional state, number of exacerbations, healthcare utilisation, health-related quality of life and family adaptability/cohesion. Other clinical outcomes will be peripheral and respiratory muscle strength, muscle thickness and cross sectional area, exercise capacity, balance and physical activity. Data will be collected at baseline, at 12 weeks, at 3- and 6-months post-PR. Changes in the outcome measures will be compared between groups, after multivariate adjustment for possible confounders, and effect sizes will be calculated. A cost-benefit analysis will be conducted. This study will enhance patients access to PR, by training healthcare professionals in the local primary healthcare centres to conduct such programmes and actively involving caregivers. The cost-benefit analysis of this intervention will provide an evidence-based insight into the economic benefit of community-based PR in chronic respiratory diseases.

The section we have examined is a persuasive and sustained demolition of the realist strategy of deriving an invariable concomitance between the existenthood of the world and the system of validation (a system accepted by both parties as being the regulator of epistemic activity). This leaves the Advaitin with an absence of invariable concomitance. This is where the Advaitin wants to be. On his view, the absence of this concomitant dependence of the system of validation on an ‘existent’ (...) world points to the possibility that the cognized world is not that independent world which Nyāya takes to be the determinate reality. If that world is not philosophically proven to be so independent, then there is at least aprima facie case for the Advaitic soteriological claim that it is Brahman alone which is ultimately real, even though the commonly cognized world allows of coherent epistemic activity. It is fair to say that such a view is established by the failure of the opponent to prove invariable concomitance between inquiry, validation and an independent world. It is the inability of the opposing view to prove a metaphysical claim which itself points to the nature of the Advaitic position; the position, that is, which suspends the need to make an ontic commitment to the extrinsic world as a determinate reality. Whether the critique of the Nyāya concept ofsattā takes us to the refutation of the Nyāya concept of a determinate world (and whether the Advaitic rejection ofsattā is of a piece with the concept of an ‘indeterminate’ world) is another issue, dealt with in detail by Śrī Har $$\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\cdot}$}}{s} $$ a elsewhere in his book, but beyond the purview of this paper.

Complex problem solving is often an integration of perceptual processing and deliberate planning. But what balances these two processes, and how do novices differ from experts? We investigate the interplay between these two in the game of SET. This article investigates how people combine bottom-up visual processes and top-down planning to succeed in this game. Using combinatorial and mixed-effect regression analysis of eye-movement protocols and a cognitive model of a human player, we show that SET players deploy both bottom-up and (...) top-down processes in parallel to accomplish the same task. The combination of competition and cooperation of both types of processes is a major factor of success in the game. Finally, we explore strategies players use during the game. Our findings suggest that within-trial strategy shifts can occur without the need of explicit meta-cognitive control, but rather implicitly as a result of evolving memory activations. (shrink)

Virtual reality (VR) through a head-mounted display (HMD) can provide new experiences. However, it remains unclear how the characteristics of HMDs affect users’ memory. To use HMDs more effectively and appropriately in several applied fields, including education, it is necessary to clarify what characteristics of HMDs affect users’ memory. A head-tracking function mounted on an HMD helps to detect the user’s head direction to enable a simulation experience akin to the real world. When we experience a simulation on (...) an HMD, we actively perceive the visual world. In this study, we assessed how active/passive viewing affects users’ memory of VR content. We conducted a psychological experiment in which participants watched a movie on an HMD. In the active viewing condition, the presented view changed depending on the participant’s head direction. In the passive viewing condition, the presented view was a recorded movie that was shown to the participants in the active viewing condition. All participants took a memory test about the content presented in the movie on the day of viewing and two weeks later. The results showed that performance on the memory test in the active viewing condition was significantly lower than that in the passive viewing condition after two weeks. This result indicated that active viewing in VR inhibited users’ memory compared to passive viewing. The current study contributes to the development of new VR techniques, such as educational learning. (shrink)

Real-world walking activity is important for poststroke patients because it leads to their participation in the community and physical activity. Walking activity may be related to adaptability to different surface conditions of the ground. The purpose of this study was to clarify whether walking adaptability on an uneven surface by step is related to daily walking activity in patients after stroke. We involved 14 patients who had hemiparesis after stroke and 12 healthy controls. The (...) poststroke patients were categorized as least limited community ambulators or unlimited ambulators. For the uneven surface, the study used an artificial grass surface. The subjects repeated even surface walking and the uneven surface walking trials at least two times at a comfortable speed. We collected spatiotemporal and kinematic gait parameters on both the even and uneven surfaces using a three-dimensional motion analysis system. After we measured gait, the subjects wore an accelerometer around the waist for at least 4 days. We measured the number of steps per day using the accelerometer to evaluate walking activity. Differences in gait parameters between the even and uneven surfaces were calculated to determine how the subjects adapted to an uneven surface while walking. We examined the association between the difference in parameter measurements between the two surface properties and walking activity. Walking activity significantly and positively correlated with the difference in paretic step length under the conditions of different surface properties in the poststroke patients and step width in the healthy controls. The strategy of increasing the paretic step length, but not step width, on an uneven surface may lead to a larger base of support, which maintains stability during gait on an uneven surface in poststroke patients, resulting in an increased walking activity. Therefore, in poststroke patients, an increase in paretic step length during gait on an uneven surface might be more essential for improving walking activity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Gerald Prince WORLDS WITH STYLE Whether it is taken to be a laudable characteristic of verbal artifacts (as in, "This essay is really well written"), a distinctive feature of an individual manner of speaking or writing (as in, "Jane definitely has a style of her own"), an ornamental supplement to that which is expressed (style as elocutio), or an appropriate way of using language in different contexts (there is (...) — or was — a style for tragedy, another one for comedy, and still another one for pastoral; there is a style for speaking at business meetings and other styles better suited to everyday conversations, political rallies, or Ph.D. exams), whether it is taken to be any of these four things (or many other things as well), the style of an utterance is traditionally viewed as a secondary phenomenon different from and added to some primary base. It is the mode of expressing a given matter, the way of "saying" some thing, the how of a what. The same is true when the notion style is used in connection with nonverbal artifacts — we talk about musical styles and about pictorial ones — but also in connection with any number of activities or states of affairs: walking down the street, dancing the tango, being pleasant, or playing ping-pong. Ping-pong players use rackets, a net, and a ball, in accordance with certain rules, when they engage in a casual game; but they are thought to be doing somediing more than merely playing: they are performing an activity (the what) in a particular way. They do it stylishly, idiosyncratically, with a lot of showboating, or in a manner appropriate to the informal context.1 It is somewhat surprising, therefore, that, when it comes to verbal (and nonverbal) representations, style is often thought to be irrelevant to the signified (what is represented) as opposed to the signifier (what represents). Graham Hough writes, for example: "In discussing whatever it is we mean by style we assume mat the primary choice, the choice of subject-matter in the large sense, has already been made.... We can talk about the secondary choice, the stylistic one, in various ways.... But whatever point of view we adopt, it will be the verbal ordonnance that we discuss, not the oudines of die mym, the facts of the case, the ideological or biographical substructure."2 Yet, as I have more than suggested, any what has (or can have) a corresponding how. Besides, both 59 60Philosophy and Literature in formal criticism and informal exchanges, we frequently seem to refer to the how of a signified. When we say, for instance, that a given short story is Kafkaesque, we do not, I think, have its verbal style in mind; and when we claim that a novelistic episode or character comes right out of Alice in Wonderland, we are not talking about linguistic matters. Of course, the fact mat we seem to refer to the how of signifieds (or that we do refer to the how of signifiers) does not necessarily mean mat mere are such things (or that we can describe them). But I suspect that there are (and that we can). I would like to discuss in what follows some of the ways in which we might be able to talk of the style of represented "worlds" more or less meaningfully and systematically and some of the problems attending such talk. For the sake of convenience and because of personal affinities, I will restrict myself to verbal narratives. I will not make a distinction between literary and non-literary ones, since such a distinction is formally and even pragmatically quite problematic. IfI concentrate on fictional narratives, it is, again, because of personal affinities and not because I mink that, when it comes to style, (ontological or other) differences between fiction and nonfiction make very much of a difference. As I will argue, style is in the eye ofthe beholder and, from that point of view, whether or not something is compossible with one's knowledge of the "real world" does not necessarily make it function as fictional or nonfictional; indeed, I am constandy surprised by the real world and I could easily recount...

One of America's foremost public intellectuals, Jean Bethke Elshtain has been on the frontlines in the most hotly contested and deeply divisive issues of our time. Now in Real Politics , Elshtain gives further proof of her willingness to speak her mind, courting disagreement and even censure from those who prefer their ideologies neat. At the center of Elshtain's work is a passionate concern with the relationship between political rhetoric and political action. For Elshtain, politics is a sphere of (...) concrete responsibility. Political speech should, therefore, approach the richness of actual lives and commitments rather than present impossible utopias. In her essays, Elshtain finds in the writings of Václav Havel, Hannah Arendt, and Albert Camus a language appropriate to the complexity of everyday life and politics, and she critiques philosophers and writers who distance us from a concrete, embodied world. She argues against those repressive strains within contemporary feminism which insist that families and even sexual differentiation are inherently oppressive. Along the way, she challenges an ideology of victimization that too often loses sight of individual victims in its pursuit of abstract goals. Elshtain reaffirms the quirky and by no means simple pleasures of small-town life as a microcosm of the human condition and considers the current crisis in American education and its consequences for democracy. Beyond exploring the details of political life over the past two decades, Real Politics advocates a via media politics that avoids unacceptable extremes and serves as a model for responsible political discourse. Throughout her diverse and insightful writings, Elshtain champions a civic philosophy that tends to the dignity of everyday life as a democratic imperative of the first order. "Jean Bethke Elshtain is a person of rare intellect. The moral wisdom that pervades these essays reminds us that when all is said and done politics is about the life and death of real people who are anything but abstractions. Her erudition is remarkable, but equally stunning is her eye for the significant. What she is so good at is helping us see the moral and political significance of the everyday."--Stanley Hauerwas, Duke University " Real Politics serves as a forceful reminder that Jean Elshtain has been dealing with the real world in twenty-five years of powerful essaying. Transcending ideological categories, she writes out of hope that human beings can enjoy those capacities of reason and faith which make them human. It is a pleasure to be reintroduced to her sustained intelligence."--Alan Wolfe, Boston University. (shrink)

Embodied theories of language postulate that language meaning is stored in modality-specific brain areas generally involved in perception and action in the real world. However, the temporal dynamics of the interaction between modality-specific information and lexical-semantic processing remain unclear. We investigated the relative timing at which two types of modality-specific information (action-based and visual-form information) contribute to lexical-semantic comprehension. To this end, we applied a behavioral priming paradigm in which prime and target words were related with respect to (...) (1) action features, (2) visual features, or (3) semantically associative information. Using a Go/No-Go lexical decision task, priming effects were measured across four different inter-stimulus intervals (ISI = 100, 250, 400, and 1000 ms) to determine the relative time course of the different features. Notably, action priming effects were found in ISIs of 100, 250, and 1000 ms whereas a visual priming effect was seen only in the ISI of 1000 ms. Importantly, our data suggest that features follow different time courses of activation during word recognition. In this regard, feature activation is dynamic, measurable in specific time windows but not in others. Thus the current study (1) demonstrates how multiple ISIs can be used within an experiment to help chart the time course of feature activation and (2) provides new evidence for embodied theories of language.

Idealized mo dels of receptive elds (RFs) can be used as building blocks for the creation of p owerful distributed computation systems. The present rep ort concentrates on inv estigating the utility of collections of RFs in representing 3D objects under changing viewing conditions. The main requirement in this task is that the pattern of activity of RFs vary as little as p ossible when the object and the camera move relative to each other. I propose a method for (...) representing objects by RF activities, based on the observation that, in the case of rotation around a xed axis, dierences of activities of RFs that are prop erly situated with resp ect to that axis remain inv ariant. Results of computational exp eriments suggest that a representation scheme based on this algorithm for the choice of stable pairs of RFs would p erform consistently b etter than a scheme inv olving random sets of RFs. The proposed scheme may be useful under object or camera rotation, b oth for ideal Lam b ertian objects, and for real-world objects such as human faces. (shrink)

The idea that experience is essentially subjective rather than of the real world is paradoxical and deeply flawed. The external world is, much more than a mere constraint, essential to meaningfully describe experience and neural activity. This is illustrated by an analysis of the phenomenology of veridical perception and by the study of experience in psychopathology by the Experience Sampling Method (ESM).

Faces carry key personal information about individuals, including cues to their identity, social traits, and emotional state. Much research to date has employed static images of faces taken under tightly controlled conditions yet faces in the real world are dynamic and experienced under ambient conditions. A common approach to studying key dimensions of facial variation is the use of facial caricatures. However, such techniques have again typically relied on static images, and the few examples of dynamic caricatures have (...) relied on animating graphical head models. Here, we present a principal component analysis -based active appearance model for capturing patterns of spatiotemporal variation in videos of natural dynamic facial behaviours. We demonstrate how this technique can be applied to generate dynamic anti-caricatures of biological motion patterns in facial behaviours. This technique could be extended to caricaturing other facial dimensions, or to more general analyses of spatiotemporal variations in dynamic faces. (shrink)

Many prepared actions have to be withheld for a certain amount of time in order to have the most beneficial outcome. Therefore, keeping track of time accurately is vital to using temporal regularities in our environment. Traditional theories assume that time is tracked by means of a clock and an “attentional gate” (AG) that modulates subjective time if not enough attentional resources are directed toward the temporal process. According to the AG theory, the moment of distraction does not have an (...) influence on the subjective modulation. Here, we show, based on an analysis of 28,354 datasets, that highly motivated players of the online multiplayer real‐time strategy game StarCraft2 indeed respond later to timed events when they are distracted by other tasks during the interval. However, transient periods of distraction during the interval influence the response time to a lesser degree than distraction just before the required response. We extend the work of Taatgen, van Rijn, and Anderson (2007) and propose an alternative active check theory that postulates that distracted attention prevents people from checking their internal clock; we demonstrate that this account better predicts variance observed in response time. By analyzing StarCraft2 data, we assessed the role of attention in a naturalistic setting that more directly generalizes to real‐world settings than typical laboratory studies. (shrink)

Long prone to dogmatic disagreement, the question of value in Marx’s thought—what value is, the purpose it serves, its application to real-world capitalism—requires renewal if Marx’s work is to remain vibrant. In _Value in Marx_, George Henderson offers a lucid rereading of Marx that strips value of its turgid theoretical reduction and reframes it as an investigation into the tensions between social relations and forms as they are rather than as what they could otherwise become. Drawing on Marx’s (...) _Capital_ and _Grundrisse_, Henderson shows how these volumes do not harbor a single theory of value that equates value to capital. Instead, these books experimentally compose and recompose value for a world that is more than capitalist. At stake is how Marx conceives of human freedom, of balanced social arrangements, and of control over the things people produce. Henderson finds that the limits on social becoming, including the tendency toward alienated existence, haunt Marx even as he looks beyond the critique of capital to an emancipated society to come. Can these limits be confronted in a creative, even joyful, way? Can they become aspects of what we desire, rather than being silenced and denied? As long as we persist in interpreting value broadly, following it as an active and not a shut-down, predetermined feature of Marx’s texts, Henderson ultimately views Marx as responding positively to these challenges and employing value as a powerful tool of the political imaginary.

Our eyes, bodies, and perspectives are constantly shifting as we observe the world. Despite this, we are very good at distinguishing between self-caused visual changes and changes in the environment: the world appears mostly stable despite our visual field moving around. This, it seems, also occurs when we are dreaming. As we visually investigate the dream environment, we track moving objects with our dream eyes, examine objects, and shift focus. These movements, research suggests, are reflected in the rapid (...) movements or saccades of our sleeping eyes. Do we really see the dream world in the same way that we see the real world? If we do, how could dreaming, usually assumed to be mind-generated hallucinations, replicate such an experience? This problem would be deflated if dreams are not hallucinations at all, but rather imagination, illusion or simply unrealistic. I argue that imagination and illusion views do not satisfactorily explain away the problem of vision and action in sleep. The imagination model is not a complete description of dreaming that is consistent with empirical research, and it is unlikely that the visual dream world is an illusion. Given that the dreaming visual experience is most likely active, hallucinatory, and at times a realistic world simulation, there are important implications for our understanding of visual perception and its relationship to movement. Evidence suggests that our dream eyes investigate the dream world as our waking eyes investigate the waking world. If changes to the unconsciously generated dream environment are perceived as external and unintentional while dream body movements are perceived as self-generated and intentional, current theory of visual perception may have to be expanded to account for how the dreaming mind generates a stable world in which we track and visually explore mind-generated objects.

We investigated the influence of globally ungrammatical local syntactic constraints on sentence comprehension, as well as the corresponding activation of global and local representations. In Experiment 1, participants viewed visual scenes with objects like a carousel and motorbike while hearing sentences with noun phrase (NP) or verb phrase (VP) modifiers like “The girl who likes the man (from London/very much) will ride the carousel.” In both cases, “girl” and “ride” predicted carousel as the direct object; however, the locally coherent combination (...) “the man from London will ride…” in NP cases alternatively predicted motorbike. During “ride,” local constraints, although ruled out by the global constraints, influenced prediction as strongly as global constraints: While motorbike was fixated less than carousel in VP cases, it was fixated as much as carousel in NP cases. In Experiment 2, these local constraints likewise slowed reading times. We discuss implications for theories of sentence processing. (shrink)

We discuss the important, but greatly under-researched, topic of the social aspects of human wayfinding during navigation. Wayfinding represents the planning and decision-making component of navigation and is arguably among the most common, real-world domains of both individual and group-level decision making. We highlight the myriad ways that wayfinding by people is not a solitary psychological process but is influenced by the actions of other people, even by their mere presence. We also present a novel and comprehensive framework (...) for classifying wayfinding in complex environments that incorporates the influence of other people. This classification builds upon the premises of previous wayfinding taxonomies and is further structured into four parts based upon (1) the nature of the interaction between the actors and (2) the time frame in which the interaction takes place. We highlight gaps in our current understanding of social wayfinding and outline future research opportunities. (shrink)

Contemporary empirical research on virtues has been promising, but limited in depth and value by investigators’ reliance on global self-report questionnaires obtained at a single time-point. These questionnaires require respondents to summarize their trait features in very broad state-ments or focus narrowly on specific behaviors. Properly understood, virtues are partly constitut-ed by appropriate motivations in response to the real-world environment and integrated with the actor’s self—features that are not accessible using the predominant research methods. Our central aim is (...) to deepen virtue research with intensive longitudinal measurement of virtu-ous activity, which includes behavior, motivation, self-congruence, and situational factors. We will assess participants’ real-world activity four times per day over a 14-day period with respect to two pervasive virtues: fairness and kindness. We will then conduct narrative interviews with a subset of participants about virtue in their lives. We will assess motivation in three ways and the integration of the behavior with the self in three ways. These innovative methods will enable us to use cutting-edge psychological methods to investigate sophisticated philosophic questions about whether and how people's capacity for virtuous activity depends on their achieving self-integration - both across time and across personal contexts.

A growing interest has been observed among K-12 school educators to incorporate maker pedagogy into science, technology, engineering, and mathematics education to engage students in the design and making process. Both cognitive engagement and emotional engagement of students can be promoted through satisfying the psychological need of relatedness that concerns a sense of connection and belonging. How to support relatedness would influence the effective development of students’ cognitive competencies, namely creativity and critical thinking, and non-cognitive characteristics, namely interest and identity. (...) Therefore, the present study investigated how two relatedness support strategies—real-world problems and mentoring influence the development of student’s STEM-related cognitive competencies and non-cognitive characteristics in STEM marker activities. We implemented a 7-week intervention study with three classes of Grade 9 students in Hong Kong. Three intervention conditions were designed in the experiment, comprising textbook problem, RWP, and RWP with mentoring. Our analysis showed that the differences in creativity among the three groups were non-significant, the RWP and RWPM groups showed stronger critical thinking than the TBP group, and the RWPM group exhibited stronger STEM interest and identity than the other two groups. This study revealed the effectiveness of adopting RWP strategy in developing secondary students’ perceived cognitive competencies and the feasibility of employing a mentoring mechanism for cultivating learners’ perceived non-cognitive characteristics. Hence, we also offered practical suggestions for teachers. (shrink)

We argue that the dead donor rule, which states that multiple vital organs should only be taken from dead patients, is justified neither in principle nor in practice. We use a thought experiment and a guiding assumption in the literature about the justification of moral principles to undermine the theoretical justification for the rule. We then offer two real world analogues to this thought experiment, voluntary active euthanasia and capital punishment, and argue that the moral permissibility of terminating (...) any patient through the removal of vital organs cannot turn on whether or not the practice violates the dead donor rule.Next, we consider practical justifications for the dead donor rule. Specifically, we consider whether there are compelling reasons to promulgate the rule even though its corresponding moral principle is not theoretically justified. We argue that there are no such reasons. In fact, we argue that promulgating the rule may actually decrease public trust in organ procurement procedures and medical institutions generally – even in states that do not permit capital punishment or voluntary active euthanasia.Finally, we examine our case against the dead donor rule in the light of common arguments for it. We find that these arguments are often misplaced – they do not support the dead donor rule. Instead, they support the quite different rule that patients should not be killed for their vital organs.

In this paper, I discuss the relationship between bodily experiences in dreams and the sleeping, physical body. I question the popular view that dreaming is a naturally and frequently occurring real-world example of cranial envatment. This view states that dreams are functionally disembodied states: in a majority of dreams, phenomenal experience, including the phenomenology of embodied selfhood, unfolds completely independently of external and peripheral stimuli and outward movement. I advance an alternative and more empirically plausible view of dreams (...) as weakly phenomenally-functionally embodied states. The view predicts that bodily experiences in dreams can be placed on a continuum with bodily illusions in wakefulness. It also acknowledges that there is a high degree of variation across dreams and different sleep stages in the degree of causal coupling between dream imagery, sensory input, and outward motor activity. Furthermore, I use the example of movement sensations in dreams and their relation to outward muscular activity to develop a predictive processing account. I propose that movement sensations in dreams are associated with a basic and developmentally early kind of bodily self-sampling. This account, which affords a central role to active inference, can then be broadened to explain other aspects of self- and world-simulation in dreams. Dreams are world-simulations centered on the self, and important aspects of both self- and world-simulation in dreams are closely linked to bodily self-sampling, including muscular activity, illusory own-body perception, and vestibular orienting in sleep. This is consistent with cognitive accounts of dream generation, in which long-term beliefs and expectations, as well as waking concerns and memories play an important role. What I add to this picture is an emphasis on the real-body basis of dream imagery. This offers a novel perspective on the formation of dream imagery and suggests new lines of research. (shrink)

In demonstration, speakers use real-world activity both for its practical effects and to help make their points. The demonstrations of origami mathematics, for example, reconfigure pieces of paper by folding, while simultaneously allowing their author to signal geometric inferences. Demonstration challenges us to explain how practical actions can get such precise significance and how this meaning compares with that of other representations. In this paper, we propose an explanation inspired by David Lewis’s characterizations of coordination and scorekeeping (...) in conversation. In particular, we argue that words, gestures, diagrams and demonstrations can function together as integrated ensembles that contribute to conversation, because interlocutors use them in parallel ways to coordinate updates to the conversational record.

The chapter deals with the notion of phenomenal realness, which was first systematically explored by Albert Michotte. Phenomenal realness refers to the impression that a perceptual object is perceived to have an autonomous existence in our mind-independent world. Perceptual psychology provides an abundance of phenomena, ranging from amodal completion to picture perception, that indicate that phenomenal realness is an independent perceptual attribute that can be conferred to perceptual objects in different degrees. The chapter outlines a theoretical framework that appears (...) particularly well-suited for dealing with corresponding phenomena. According to this framework, perception can be understood as a triggering of conceptual forms by sensor inputs. It is argued that the attribute of phenomenal realness is based on specific types of internal evaluation functions which deal with the segregation of causes conceived as ‘external’ from those conceived as ‘internal’. These evaluation functions integrate different internal sources of ‘knowledge’ about the potential causes for the activation of conceptual forms and provide markers by which conceptual forms can be tagged as ‘external world objects’.

The celebrated Russian philosopher, Evald Ilyenkov, draws on Spinoza to solve a key philosophical problem: how exactly does the mind connect to the real world? However, the proposed solution has come under much criticism, for example in a recent special issue of Studies of East European Thought (74, 3). This paper aims to clearly explain the solution, overcoming misunderstandings that are evident in the special issue. The kernel of the solution is an argument that human cognition rests on (...) practical activity. In practical activity humans do not act on a fixed structure within their own bodies, in the manner, say, that the activity of water is determined by its fixed structure, H2O. Instead, human practical activity directly connects with and continually adapts to the structures and causal powers of external bodies. Awareness of practical activity thereby gives the human mind access to a mode of activity that is in direct contact and ever-greater accordance with the objects of the real world. The paper will elaborate and develop this kernel, with particular attention to the notion of ‘causal powers’ that it contains, by drawing from the revival in philosophy and the social sciences of what has been termed ‘causal powers realism’. The paper thereby opens new insights and connections regarding the Spinoza-Ilyenkov solution, alleviating the potential for misunderstandings evident in the special issue. (shrink)

I am struck by how little is known about so much of cognition. One goal of this paper is to argue for the need to consider a rich set of interlocking issues in the study of cognition. Mainstream work in cognition—including my own—ignores many critical aspects of animate cognitive systems. Perhaps one reason that existing theories say so little relevant to real world activities is the neglect of social and cultural factors, of emotion, and of the major points (...) that distinguish an animate cognitive system from an artificial one: the need to survive, to regulate its own operation, to maintain itself, to exist in the environment, to change from a small, uneducated, immature system to an adult, developed, knowledgeable one.Human cognition is not the same as artificial cognition, if only because the human organism must also be concerned with the problems of life, of development, of survival. There must be a regulatory system that interacts with the cognitive component. And it may well be that it is the cognitive component that is subservient, evolved primarily for the benefit of the regulatory system, working through the emotions, through affect.I argue that several concepts must become fundamental parts of the study of cognition, including the roles of culture, of social interaction, of emotions, and of motivation. I argue that there are at least 12 issues that should comprise the study of cognition, and thereby, the field of Cognitive Science. We need to study a wide variety of behavior before we can hope to understand a single class. Cognitive scientists as a whole ought to make more use of evidence from the neurosciences, from brain damage and mental illness, from cognitive sociology and anthropology, and from clinical studies of the human. These must be accompanied, of course, with the study of language, of the psychological aspects of human processing structures, and of artificially intelligent mechanisms. The study of Cognitive Science requires a complex interaction among different issues of concern, an interaction that will not be properly understood until all parts are understood, with no part independent of the others, the whole requiring the parts, and the parts the whole.

If we don't get Sunday right, we won't get Monday--or any day of the workweek--right. The divided life is a temptation so built into our society, we may not even recognize it. Yet most of us fall prey to it. We either undervalue work, resenting it as simply a job, or we overvalue it as an identity-defining career. Michael Naughton, drawing on his background in both business and theology, proposes that the key to finding balance is another important human (...) class='Hi'>activity: leisure. In light of leisure--not mere amusement, but time for family, silence, prayer, and above all, worship--work becomes a space where men and women can find deep fulfilment.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Evangelical Peacemakers: Gospel Engagement in a War-Torn World ed. by David P. GusheeLisa Sowle CahillEvangelical Peacemakers: Gospel Engagement in a War-Torn World Edited by David P. Gushee EUGENE, OR: WIPF AND STOCK, 2013. 135 PP. $21.00This short volume collects papers from a 2012 Evangelicals for Peace conference at Georgetown University. This should not mislead potential readers as to the book's timeliness, coherence, significance, or ecumenical and (...) interreligious appeal. Much of its incisive analysis owes to the editor's preface, introductory chapter, and concluding critical discussion of the positions represented, including his own.Four chapters lay out the Christian arguments for just war, biblical pacifism, and the late Glen Stassen's "just peacemaking theory," presenting ten practices to deter or transform violent conflict. Although Gushee's chapter would have to be placed among just war theorists, he stresses that war must be a last resort to defend innocent life, carried out with the least violence possible. Gushee appreciates the paradox of expressing love through acts of violence. Lisa Sharon Harper insists this goes beyond paradox to outright denial of the redemption Jesus brings, failing to honor the image of God in all persons. Following Anglican theologian Oliver O'Donovan, Erik Patterson sees publicly authorized force to protect society as a positive Christian duty. Striving to unite these two sides in practice, Stassen derives alternative, nonviolent strategies from the Sermon on the Mount to transform conflict at the local, national, regional, and international levels.But are such efforts successful? Can and do Christian peacemakers actually bring about significant societal and political change? Twelve further chapters offer experience-based evidence from Evangelical organizations and ministries that the answer is yes. Authors describe initiatives at home and abroad, giving special attention to Christian–Muslim outreach and understanding. Examples range from Evangelical pastors and churches welcoming Muslims and mosques; to educational ventures in Pakistani madrassas; to organizing Afghan youth as "peace volunteers"; to conflict mediation in Egypt and Indonesia; and the memoir of a Lockerbie bombing victim's sister, who went personally to reconcile with Muammar Gaddafi. Sojourners editor Jim Wallis gives plenty of illustrations of the power in the United States of massive civil disobedience and efforts to pressure Congress or the president through letter and phone campaigns, protests, media attention, and high-level advocacy. Christian political resistance and mobilization can no longer be dismissed as utopian, naïve, or marginal. In many cases, it works.Gushee honestly and acutely articulates why pacifism and just war have had longstanding places in Christian political ethics, and why their adherents are [End Page 206] not easily reconciled. First, Jesus was nonviolent, and even those who construe rare and restrained violence as a form of neighbor love cannot deny that Jesus himself never expressed love in this way (121). Second, although Jesus calls disciples to participate in God's reign, that reign is but "eschatologically" present in a fallen world (119). Violence-transforming practices do not always work (125). Reconciling love may define kingdom discipleship, but when do we gauge love-in-action by the "present" reality of the kingdom, and when by the "not yet"? Third, according to Gushee, there is a difference (not separation) between church and government. This yields the conundrum that although their roles are different, Christians participate in both spheres, responsible not only for the peacemaking activities of the church but also for their social effects and for building just structures (5–6).Gushee does not claim to resolve these paradoxes. The collection underscores a more urgent challenge: to embody and expand Evangelical peacemaking as an integral dimension of discipleship and a powerful form of real-world politics. This book furthers theological-ethical analysis while leading scholars, students, and congregations to become active agents of change.Lisa Sowle CahillBoston CollegeCopyright © 2017 Society of Christian Ethics...

Dragon boat sport is a traditional activity in China. In recent years, dragon boat sport has become more and more popular around the world. In order to face more challenges, it is urgent for athletes to enhance their own strength. Scientific training methods are particularly important for athletes, and accurate training data are the basis to support scientific training. Traditional mathematical statistic methods neither can sample signals accurately nor can they do real-time analysis and feedback the characteristics (...) to each athlete. In this paper, we use the wearable device with a triaxial accelerometer and heart rate sensor builtin to sample the speed signals and heart rate signals of athletes in various stages of men’s 1000m straight race. Based on the complex network theory, we regard the 23 dragon boat athletes in the dragon boat race as 23 nodes so as to establish a network with 23 nodes and reflect the importance of nodes by measuring the impact of node deletion on the results of the race. The neural network multilayer perceptron model is used for training to obtain the optimal combined value with speed and heart rate for each race stage. The optimal value will be used in the simulated race as the target value to verify if it can help to improve the training efficiency. Experimental results show that the optimal value obtained by this method has a positive effect on the results of the dragon boat race which is beneficial to sports training and tactics planning.

According to my entire understanding here, art is itself an emanation of the absolute. The history of art will show us most revealingly its immediate connections to the conditions of the universe and thereby to that absolute identity in which art is preordained. Only in the history of art does the essential and inner unity of all works of art reveal itself, a unity showing that all poetry is of the same spirit, a spirit that even in the antitheses of (...) ancient and modern art is merely showing its two different faces. §14. The indifference of the ideal and the real as indifference manifests itself in the ideal world through art, for art is in itself neither mere activity nor mere knowledge, but is rather an activity completely permeated by knowledge, or in a reverse fashion knowledge that has completely become activity. That is, it is the indifference of both. (shrink)

Metaphysics relies on the presupposition of the non-being of the world: since the world has once not existed it is necessary to postulate a cause for its existence, i.e. an extrinsic principle to explain the absolute beginning of the causal series of all things that constitute the world. After the critique of theologizing metaphysics by authors like Kant, Hegel and Nietzsche, the notion of an absolute beginning still persists though in a field in which it often goes (...) as such unnoticed, while it factually enjoys wide acceptance, namely in epistemology. It sounds as a truism that knowledge begins: personal inexistence (birth-death cycle) and the phenomenon of unconsciousness (sleep-wake cycle) seem to endorse the obviousness of that statement. Now, to link the beginning of the phenomenal series of subjective acts of knowledge with the existence of an external world that causes the specific content of our temporary cognitive acts relies, however, on two presuppositions, namely on the thesis of a complete non-being or nothingness of knowledge and, intrinsically related to this first presupposition, on the thesis of an absolute beginning of cognitive activity. If knowledge begins from its own nothingness, there must be a cause that is external to the totality of acts of knowledge, a cause that it doesn´t belong to the series of cognitive acts and, therefore, that it is not caused by any of them: this uncaused cause of contentful knowledge is supposed to be the real world external to the knowing subject. In my paper I make explicit the relation between realist-empiricist approachs to epistemology and the double presupposition of the nothingness and absolute beginning of knowledge, I explain the difficulties implied by these two presuppositions and, finally, I propose as a plausible solution to those difficulties some key theoretical claims of absolute idealism.
