With the development of office forms, the space form of super high-rise office buildings changed from the unitary efficient office space to a complex space that integrated office, communication, and experience, which also diversified the design of typical floors in the office zone. However, from the perspective of fire prevention, the placement of shared space changed the form of the plane in typical floors in the office zone, affecting the smoke spreading of fire and (...) paths of personnel evacuation. Hence, the subject on the planar relationship among high-rise office buildings based on fire prevention analysis, which optimizes space design, is worthy of discussion. After collecting many cases of super high-rise office buildings in China, this study categorized them into six typical planes and adopted the software PyroSim for comparative simulation of the smoke spreading of fire. By comparing the visibility of different zones in fires, this study analyzed the effects of the area of the office zone, the location of the atrium, and the form of the plane on the fire visibility on the typical floor and put forth the key factors that influence fire visibility, thus optimizing the plane design of the typical floor of super high-rise buildings. The findings show that in the six fire scenes, the area of the office zone is between 1136m2 and 1736m2. The peak of duration for visibility decline at 1.5 m appeared in Scene 3. Its office zone is 1536m2, and the duration of visibility decline is greater than 1000 s. In other fire scenes, the duration of visibility decline is less than 300 s. By comparing the plane arrangement features of the fire scenes, the paper concludes that in a given fire scene, establishing an atrium in the office zone, expanding the length of the adjacent edge between the atrium and the office zone, and building an evacuation corridor between the atrium and the core tube can greatly extend the effective evacuation time. This can serve as reference for the plane design of super high-rise office buildings. (shrink)

Claudian compares Eutropius in his consular robes to a monkey, dressed in silk to amuse dinner guests, but with his buttocks bare . The situation has not failed to attract the notice of scholars. Christiansen and Fargues called attention to the striking and original use of the monkey-simile . Alan Cameron has suggested that the present example is drawn from life: ‘Who can doubt that this was a typical dinner divertissement in the elegant circles of Claudian's day-or at least one (...) Claudian himself had witnessed?’ He cites E. R. Curtius's assertion that metaphorical apes are uncommon in ancient literature ; that may be relatively true, but when Demosthenes is entitled to address his opponent as similar licence in subsequent invective is unlimited.

The words in children's language learning environments are strongly predictive of cognitive development and school achievement. But how do we measure language environments and do so at the scale of the many words that children hear day in, day out? The quantity and quality of words in a child's input are typically measured in terms of total amount of talk and the lexical diversity in that talk. There are disagreements in the literature whether amount or diversity is the more critical (...) measure of the input. Here we analyze the properties of a large corpus of speech to children and simulate learning environments that differ in amount of talk per unit time, lexical diversity, and the contexts of talk. The central conclusion is that what researchers need to theoretically understand, measure, and change is not the total amount of words, or the diversity of words, but the function that relates total words to the diversity of words, and how that function changes across different contexts of talk.

Street-level bureaucracy literature ascertains that policies get made not only in the offices of legislatures or politicians but through the discretion bureaucrats employ in their day-to-day interactions with citizens in government agencies. The discretion bureaucrats use to grant access to public benefits or impose sanctions adds up to what the public ultimately experience as the government and its policies. This perspective, however, overlooks policy-making that gets done in the back offices of government, where there might not be direct interaction with (...) citizens. Furthermore, it treats discretion as inherently anthropogenic and ignores that it is exercised in relation to sociotechnical arrangements of which bureaucrats are a part. In this paper, based on extensive ethnography at national statistical institutes and international statistical meetings across Europe, I make two arguments. The first is that, statisticians emerge as back-office policy-makers as they are compelled to take multiple methodological decisions when operationalizing abstract statistical guidelines and definitions, thus effectively making rather than merely implementing policies. This is the “discretion” they employ, even when they may not interact with citizens. The second argument is that the exercise of discretion is sociotechnical, that is, it happens in relation to the constraints and affordances of technologies and the decisions of other bureaucrats in their institutions and others.

Mindreading (or folk psychology, Theory of Mind, mentalizing) is the capacity to represent and reason about others’ mental states. The Simulation Theory (ST) is one of the main approaches to mindreading. ST draws on the common-sense idea that we represent and reason about others’ mental states by putting ourselves in their shoes. More precisely, we typically arrive at representing others’ mental states by simulating their mental states in our own mind. This entry offers a detailed analysis of ST, considers (...) theoretical arguments and empirical data in favour of and against it, discusses its philosophical implications, and illustrates some alternatives to it.

Human conflict and its resolution is obviously a subject of great practical importance. Equally obviously, it is a vast subject, ranging from total war at one end of the spectrum to negotiated settlement at its other end. The literature on the subject is correspondingly vast and, in recent times, technical, thanks to the valuable contributions made to it by game theorists, economists, and writers on industrial and international relations. In this essay, however, I shall discuss only one familiar form of (...) conflict-resolution. There is room for such a discussion, because philosophers have lately neglected compromise, despite the interest shown in it by the aforementioned experts, and despite the classic treatments of it by Halifax, Burke and Morley. Truly, ‘…compromise is not so widely discussed by philosophers as one might expect’, and ‘…the idea of compromise has been largely neglected by Anglo-American jurisprudence’. (shrink)

This is the first full-length biography of John Langshaw Austin (1911–60). The opening four chapters outline his origins, childhood, schooling, and time as an undergraduate, while the next four examine his early career in professional philosophy, looking at the influence of Oxford Realism, Logical Positivism, Pragmatism, and the later Wittgenstein. The central twelve chapters then explore Austin’s wartime career in British Intelligence. The first three examine the contributions he made to the campaigns in North Africa; the next seven the seminal (...) role he played in ensuring the outstanding accuracy of the D-Day Intelligence; while the final two explore his contributions to Arnhem, the Ardennes, and the post-war administration of Germany. The last main section of the book then outlines and assesses Austin’s contributions to post-war Oxford Ordinary Language Philosophy. The first three chapters discuss the impact on Oxford philosophy of the cultural atmosphere of post-war Britain and the later Wittgenstein’s ideas. The next four look at Austin’s influence on post-war Oxford, particularly his Saturday morning discussion group and his perception lectures. The next five chapters concentrate on America’s influence on Austin and vice versa, paying particular attention to Austin’s work on speech-acts and his semesters in Harvard and Berkeley. The final two chapters examine Austin’s declining influence in Oxford, and his tragically premature death. (shrink)

According to a popular strategy amongst economists and philosophers, in order to solve the problem of interpersonal utility comparisons, we have to look at how ordinary people make such comparisons in everyday life. The most recent attempt to develop this strategy has been put forward by Goldman in his “Simulation and Interpersonal Utility” (Ethics 4:709–726, 1995). Goldman claims, first, that ordinary people make interpersonal comparisons by simulation and, second, that simulation is reliable for making interpersonal comparisons. In this paper, I (...) focus on Goldman’s latter claim. After updating Goldman’s account of how ordinary people make interpersonal comparisons in the light of Goldman’s newest formulation of his simulation theory of mental ascription (Goldman, Simulating Minds. Oxford University Press, Oxford, 2006), I develop and assess Goldman’s arguments in favour of the reliability of simulation for interpersonal comparisons. I argue that, under certain conditions, there may be room for a scientifically acceptable solution to the problem of interpersonal utility comparisons. (shrink)

In this paper, we demonstrate how the collaborative and sequential unfolding of a story ties into the constitution of a membership categorization device which we have glossed as ‘us and them’. The data come from a focus group activity where first and second generation immigrants to Denmark have been asked to discuss their situation in Denmark. Using Ethnomethodological Conversation and Membership Categorization Analysis, we present one story which involves a story-teller and his family and an elderly Danish couple living in (...) the same block of flats. In the telling of the story, co-participants align and affiliate, and disalign and disaffiliate, at sequentially relevant junctions. We will argue that not only do such phenomena indicate listenership and possible agreement to the moral of the story in its telling, but also to the morally implicative categorical work involved in the story’s telling.

John Bowlby's use of evolutionary theory as a cornerstone of his attachment theory was innovative in its day and remains useful. Del Giudice's target article extends Belsky et al.'s and Chisholm's efforts to integrate attachment theory with more current thinking about evolution, ecology, and neuroscience. His analysis would be strengthened by (1) using computer simulation to clarify and simulate the effects of early environmental stress, (2) incorporating information about non-stress related sources of individual differences, (3) considering the possibility of adaptive (...) behavior without specific evolutionary adaptations, and (4) considering whether the attachment construct is critical to his analysis.

Stanley Cavell isn't the first to arrive at philosophy through a life with music. Nor is he the first whose philosophical practice bears the marks of that life. Much of Cavell's life with music is confirmed for the world in his philosophical autobiography Little Did I Know. A central moment in that book is Cavell's describing the realization that he was to leave his musical career behind – for what exactly, he did not yet know. He connects the memory-shock of (...) this leaving with "the work of mourning." How does such a life out of music inform Cavell's philosophical sensibility? The thought I follow in this essay is that Cavell's distinctive orientation in philosophy – call this his lifelong coming to terms with his abandoning a life in music – is guided in part by an interest in those moments in experience where words seem to run out, or veer toward nonsense, leaving in their wake touchstones of ecstasy. I explore this idea by summarizing my exchange with Stanley Cavell years ago when I asked him whether certain passages from his essay "Music Discomposed" are depictions of the unsayable. Cavell's response is elaborated, or qualified, by considering a pair of moments in Little Did I Know where words appear to run out. I conclude by discussing culminating thoughts on the burden borne by words and their failure that appear in Cavell's late essay on music, "Impressions of Revolution.". (shrink)

In the 1990s, Building Information Modeling (BIM) software significantly altered architectural approaches to planning and building. Based on parametric methods, BIM technologies sought to simulate the construction process prior to a building’s realisation. These computer simulations challenged the existing practice of representing a building through plan, section and elevation, proposing that one computational model could create a more efficient way of building. The history of BIM explorations and applications, while hardly linear, can be traced back to developments in computing since (...) the post-war period. This article maps some of these histories by examining how the computational model became an organisational infrastructure, collecting data about design and building parameters, and facilitating knowledge transfer across industries. Special attention will be given to the foundational role of Charles Eastman’s work on a Building Description System (BDS) in the 1970s, as well as Robert Aish’s contribution to RUCAPS, one of the earliest applications of Building Modeling for the design of parametric structures. I will further address research on interface technologies and computational curve modelling as well as the popularisation of Building Information systems through the office of Gehry Partners. By highlighting the interrelated nature of technology and cultural shifts in the making of BIM, this contribution sheds light on the epistemic status of computer simulations in architecture, and the dynamics of the design and building processes in which they are used.

In this paper, various dimensions of care involved in mathematics education are linked to the need to develop classroom activities that connect mathematics and social justice issues. Drawing from literature that shows cognition is situated and embodied, the importance of meaningful contextualization and social interaction when learning mathematics is highlighted. The concept of “simulation-based mathematics and social justice activities” is presented as an approach for the work of bringing social justice issues that have mathematics at their core to the classroom. (...) Theoretical constructs and examples are discussed, to illustrate what such simulations may entail and what may be learned from scholars, in different educational fields, who use simulations in classroom activities. Potentially beneficial features of social justice simulations are related to various educational goals, such as: decreasing arbitrary boundaries between mathematical sub-areas and between mathematics and other disciplines; providing opportunities for choice and the embodiment of different perspectives; and offering opportunities for inter-personal learning. I report on a simulation-based mathematics and social justice activity, conducted in a teacher education classroom. Students—in this case future teachers—were prompted to write reflectively about their participation in the activity. My interest lies in finding out what, if any, cognitive and affective benefits these prospective teachers connect with their experience of mathematics in the activity. To investigate this, I analyze six themes that are present in the data and illustrate each theme using excerpts of student writing. The thematic analysis allows us to learn about connections made by these students, between mathematics, in the context of the activity, and issues that are personally meaningful to them, such as: their own future teaching practice, learning and interacting with peers, beliefs and feelings about mathematics and the learning of mathematics, and different perspectives on complex decisions, involving cooperation or lack thereof, that are encountered in real life situations.

Shahriar S. Afshar claimed that his 2007 modified version of the double-slit experiment violates complementarity. He makes two modifications to the standard double-slit experiment. First, he adds a wire grid that is placed in between the slits and the screen at locations of interference minima. The second modification is to place a converging lens just after the wire grid. The idea is that the wire grid implies the existence of interference minima, while the lens can simultaneously obtain which-way information. More (...) recently, Cramer argued that the experiment bolstered the Transactional Interpretation of Quantum mechanics. His argument scrutinizes Bohr’s complementarity in favor of TIQM. We analyze this experiment by simulation using the path integral formulation of quantum mechanics and find that it agrees with the wave-particle duality relation given by Englert, Greenberg and Yasin. We conclude that the use of Afshar’s experiment to provide a testbed for quantum mechanical interpretations is limited. (shrink)

In recent years, more and more people are applying Convolutional Neural Networks to the study of sound signals. The main reason is the translational invariance of convolution in time and space. Thereby the diversity of the sound signal can be overcome. However, in terms of sound direction recognition, there are also problems such as a microphone matrix being too large, and feature selection. This paper proposes a sound direction recognition using a simulated human head with microphones at both ears. Theoretically, (...) the two microphones cannot distinguish the front and rear directions. However, we use the original data of the two channels as the input of the convolutional neural network, and the resolution effect can reach more than 0.9. For comparison, we also chose the delay feature (GCC) for sound direction recognition. Finally, we also conducted experiments that used probability distributions to identify more directions.

This paper examines the relation of social media to political discourse in light of Bruno Latour’s notion of political discourse being (innately and positively) “crooked” (se courber) in his book, An Inquiry into Modes of Existence: An Anthology of the Moderns. In this book, Latour argues for a geometry of political rhetoric and its claims to truth that is the reverse of the Western philosophic tradition’s. This article looks at that geometry from the aspect of rhetorical strategies of fragment and (...) punctuation, empowered by the form and use of social media. It examines such in the presidential campaign of Donald Trump in the United States of America during 2015-2016. Contrasts and connections to earlier, ‘old media,’ mediums and technologies, such as that of modern journalism and radio are made. (shrink)

According to Berkeley, then, the unconscious process of inference of the scientist goes as follows. He notices that, when he does not have his house within visual range, he cannot see it just by wishing to; and that, when he does have it within visual range and his eyes open, he cannot prevent himself from seeing it just by wishing not to. He therefore infers that he is not the efficient cause of these sensations. But, since he holds that they (...) must have some efficient cause, he concludes that this is a congeries of "material substances," which are numerically distinct and partly dissimilar from the sensations, and which exist even when unperceived, or "externally to the mind." As a psychological theory, this seems to be at any rate plausible. (shrink)

Now that complex Agent-Based Models and computer simulations spread over economics and social sciences - as in most sciences of complex systems -, epistemological puzzles (re)emerge. We introduce new epistemological tools so as to show to what precise extent each author is right when he focuses on some empirical, instrumental or conceptual significance of his model or simulation. By distinguishing between models and simulations, between types of models, between types of computer simulations and between types of empiricity, section 2 gives (...) conceptual tools to explain the rationale of the diverse epistemological positions presented in section 1. Finally, we claim that a careful attention to the real multiplicity of denotational powers of symbols at stake and then to the implicit routes of references operated by models and computer simulations is necessary to determine, in each case, the proper epistemic status and credibility of a given model and/or simulation.

This essay provides an introduction to the terminology, concepts, methods, and challenges of image‐based modeling in biology. Image‐based modeling and simulation aims at using systematic, quantitative image data to build predictive models of biological systems that can be simulated with a computer. This allows one to disentangle molecular mechanisms from effects of shape and geometry. Questions like “what is the functional role of shape” or “how are biological shapes generated and regulated” can be addressed in the framework of image‐based systems (...) biology. The combination of image quantification, model building, and computer simulation is illustrated here using the example of diffusion in the endoplasmic reticulum. (shrink)

Mental simulation — such as imagining tilting a glass to figure out the angle at which water would spill — can be a way of coming to know the answer to an internally or externally posed query. Is this form of learning a species of inference or a form of observation? We argue that it is neither: learning through simulation is a genuinely distinct form of learning. On our account, simulation can provide knowledge of the answer to a query even (...) when the basis for that answer is opaque to the learner. Moreover, through repeated simulation, the learner can reduce this opacity, supporting self-training and the acquisition of more accurate models of the world. Simulation is thus an essential part of the story of how creatures like us become effective learners and knowers. (shrink)

In this paper, I argue that a natural selection-based perspective gives reasons for thinking that the core of the ability to mindread cognitively complex mental states is subserved by a simulationist process—that is, that it relies on nonspecialised mechanisms in the attributer's cognitive architecture whose primary function is the generation of her own decisions and inferences. In more detail, I try to establish three conclusions. First, I try to make clearer what the dispute between simulationist and non-simulationist theories of mindreading (...) fundamentally is about. Second, I try to make more precise an argument that is sometimes hinted at in support of the former: this 'argument from simplicity' suggests that, since natural selection disfavours building extra cognitive systems where this can be avoided, simulationist theories of mindreading are more in line with natural selection than their competitors. As stated, though, this argument overlooks the fact that building extra cognitive systems can also yield benefits: in particular, it can allow for the parallel processing of multiple problems and it makes for the existence of backups for important elements of the organism's mind. I therefore try to make this argument more precise by investigating whether these benefits also apply to the present case—and conclude negatively. My third aim in this paper is to use this discussion of mindreading as a means for exploring the promises and difficulties of evolutionary arguments in philosophy and psychology more generally.

Those who believe suitably programmed computers could enjoy conscious experience of the sort we enjoy must accept the possibility that their own experience is being generated as part of a computerized simulation. It would be a mistake to dismiss this is just one more radical sceptical possibility: for as Bostrom has recently noted, if advances in computer technology were to continue at close to present rates, there would be a strong probability that we are each living in a computer simulation. (...) The first part of this paper is devoted to broadening the scope of the argument: even if computers cannot sustain consciousness (as many dualists and materialists believe), there may still be a strong likelihood that we are living simulated lives. The implications of this result are the focus of the second part of the paper. The topics discussed include: the Doomsday argument, scepticism, the different modes of virtual life, transcendental idealism, the Problem of Evil, and simulation ethics. (shrink)

Are public officials morally justified in threatening violence, engaging in deception, or forcing citizens to act for their own good? Can individual officials be held morally accountable for the wrongs that governments commit? Dennis Thompson addresses these questions by developing a conception of political ethics that respects the demands of both morality and politics. He criticizes conventional conceptions for failing to appreciate the difference democracy makes, and for ascribing responsibility only to isolated leaders or to impersonal organizations. His book seeks (...) to recapture the sense that men and women, acting for us and together with us in a democratic process, make the moral choices that govern our public life. Thompson surveys ethical conflicts of public officials over a range of political issues, including nuclear deterrence, foreign intervention, undercover investigation, bureaucratic negligence, campaign finance, the privacy of officials, health care, welfare paternalism, drug and safety regulation, and social experimentation. He views these conflicts from the perspectives of many different kinds of public officials - elected and appointed executives at several levels of government, administrators, judges, legislators, governmental advisers, and even doctors, lawyers, social workers, and journalists whose professional roles often thrust them into public life. In clarifying the ethical problems faced by officials, Thompson combines theoretical analysis with practical prescription, and begins to define a field of inquiry for which many have said there is a need but to which few have yet contributed. Philosophers, political scientists, policy analysts, sociologists, lawyers, and other professionals interested in ethics in government will gain insight from this book. (shrink)

The purpose of this article is to construct a critique of some works by the French artist Lucy Schwob, better known as Claude Cahun, who was active between 1910 and 1950. A writer and photographer, Cahun was at first very close to symbolist positions; later she was closer to the surrealist movement. Her work and her life, continually suspended between genders, and between ‘normality’ and ‘deviance’, have so far been analysed mainly through gender studies. This article attempts to restore the (...) inherent complexity of her poetic work and aesthetic. It tries to widen the field of study to deal with the representation of alterity, through reversing the stereotypical representation. (shrink)

While cochlear implantation has benefitted many patients with single-sided deafness (SSD), there is great variability in cochlear implant (CI) outcomes and binaural performance remains poorer than that of normal-hearing (NH) listeners. Differences in sound quality across ears – temporal fine structure (TFS) information with acoustic hearing versus coarse spectro-temporal envelope information with electric hearing – may limit integration of acoustic and electric patterns. Binaural performance may also be limited by inter-aural mismatch between the acoustic input frequency and the place of (...) stimulation in the cochlea. SSD CI patients must learn to accommodate these differences between acoustic and electric stimulation to maximize binaural performance. It is possible that training may increase and/or accelerate accommodation and further improve binaural performance. In this study, we evaluated lateralization training in NH subjects listening to broad simulations of SSD CI signal processing. A 16-channel vocoder was used to simulate the coarse spectro-temporal cues available with electric hearing; the degree of inter-aural mismatch was varied by adjusting the simulated insertion depth (SID) to be 25 mm (SID25), 22 mm (SID22), and 19 mm (SID19) from the base of the cochlea. Lateralization was measured using headphones and head-related transfer functions (HRTFs). Baseline lateralization was measured for unprocessed speech (UN) delivered to the left ear to simulate SSD and for binaural performance with the acoustic ear combined with the 16-channel vocoders (UN+SID25, UN+SID22, and UN+SID19). After completing baseline measurements, subjects completed 6 lateralization training exercises with the UN+SID22 condition, after which performance was re-measured for all baseline conditions. Post-training performance was significantly better than baseline for all conditions (p<0.05 in all cases), with no significant difference in training benefits among conditions. Given that there was no significant difference between the SSD and the SSD CI conditions before or after training, the results suggest that NH listeners were unable to integrate TFS and coarse spectro-temporal cues across ears for lateralization, and that inter-aural mismatch played a secondary role at best. While lateralization training may benefit SSD CI patients, the training may largely improve spectral analysis with the acoustic ear alone, rather than improve integration of acoustic and electric hearing.

The essays in this volume make it abundantly clear that there is no shortage of disagreement about the plausibility of the simulation theory. As we see it, there are at least three factors contributing to this disagreement. In some instances the issues in dispute are broadly empirical. Different people have different views on which theory is favored by experiments reported in the literature, and different hunches about how future experiments are likely to turn out. In 3.1 and 3.3 we will (...) consider two cases that fall under this heading. With a bit of luck these disputes will be resolved as more experiments are done and more data become available. Faulty arguments are a second source of disagreement. In 3.2 and 3.4 we will set out two dubious arguments advanced by our critics and try to explain exactly why we think they are mistaken. The third source of disagreement is terminological. Terms like "theory-theory," "simulation theory" and a number of others are often not clearly defined, and they are used in different ways by different authors. (Worse yet, we suspect they are sometimes used in different ways by a single author on different occasions). Thus it is sometimes the case that what appears to be a substantive disagreement turns out to be simply a verbal dispute. Moreover, since the labels "theory-theory" and "simulation theory" are each used to characterize a broad range of theories, it may well turn out that some of the theories falling under both headings are correct. In Sections 1 and 2, we will set out a variety of different views for which the labels "theory-theory" and "simulation theory" might be used. As we proceed we'll point out a number of places where disagreements diminish when distinctions among different versions of the theory-theory and the simulation theory are kept clearly in mind.

Monte Carlo simulations arrive at their results by introducing randomness, sometimes derived from a physical randomizing device. Nonetheless, we argue, they open no new epistemic channels beyond that already employed by traditional simulations: the inference by ordinary argumentation of conclusions from assumptions built into the simulations. We show that Monte Carlo simulations cannot produce knowledge other than by inference, and that they resemble other computer simulations in the manner in which they derive their conclusions. Simple examples of Monte Carlo simulations (...) are analysed to identify the underlying inferences. (shrink)

"Lest one think that the focus on aspect-seeing in Wittgenstein is only a means to more contemporary philosophical ends, one ought to read Day’s remarkable 'Wanting to Say Something: Aspect-Blindness and Language'. Day considers the issue of aspect-blindness, arguing that universal aspect-blindness is impossible for beings with language. Specifically, he shows that a child’s first attempt at language, at trying “bloh” for “ball,” is neither an indication that the child sees the ball for the first time, nor an indication that (...) the child is giving a first label for an object seen all along. Rather, he shows that this attempt is an indication of the dawning of an aspect. The dawning of aspects, so common during the phase of language acquisition, becomes supplanted by language itself. Universal aspect-blindness is not humanly possible, then. Day argues that the acquisition of language results in a loss of desire for aspects (which it is possible to regain through art). Localized aspect-blindness is familiar because as language-users, we have lost our desire for aspects. Day then turns to questions about the deep purpose behind Wittgenstein’s style. Why are those doubting voices prominent? Why does Wittgenstein demand so often that the reader answer his questions? Day shows that these elements of Wittgenstein’s style arise from a motivation to regain his own desire for aspects, and he wants to re-awaken our own desire for aspects. Day motivates us to consider aspect-seeing in order to see Wittgenstein himself anew." --Chris Weigel, Book Review of Seeing Wittgenstein Anew, Journal of the History of Philosophy 49:2 (April 2011): 263.

Herman Levin Goldschmidt delineates and critiques four types of “dialogism,” four ways of derailing dialogical discourse and praxis. In the following, I examine two of them: “Pan-dialogism” is the glossing over the effect of power differentials such as gender, class, and race as relevant factors in the constitution of dialogue. “Pluralogic” is the evading of true dialogue, which is intense and exclusive, by conducting simultaneously multiple superficial conversations. Pluralogic enables to escape the internal turmoil and conscience’s call for critiquing that (...) are part and parcel of true dialogue. To examine the two dialogisms, I use Martin Buber’s thought, which Goldschmidt sees himself as continuing, as a case in point as well as a resource to further unpack Goldschmidt’s thought. In the course of the paper, I criticize what I call “Human Resource Office Morality,” the celebration of mere diversity at the expense of true contradiction. (shrink)

This paper examines several issues related to information, speed of computation, and simulation of a physical process. It is argued that mental processes proceed at a rate close to the optimal based on thermodynamic considerations. Problems related to the simulation of a quantum mechanical system on a computer are reviewed. Parallels are drawn between biological and adaptive quantum systems.

The same neural structures involved in the unconscious modeling of our acting body in space also contribute to our awareness of the lived body and of the objects that the world contains. Neuroscientific research also shows that there are neural mechanisms mediating between the multi-level personal experience we entertain of our lived body, and the implicit certainties we simultaneously hold about others. Such personal and body-related experiential knowledge enables us to understand the actions performed by others, and to directly decode (...) the emotions and sensations they experience. A common functional mechanism is at the basis of both body awareness and basic forms of social understanding: embodied simulation. It will be shown that the present proposal is consistent with some of the perspectives offered by phenomenology. (shrink)

How do people evaluate causal relationships? Do they just consider what actually happened, or do they also consider what could have counterfactually happened? Using eye tracking and Gaussian process modeling, we investigated how people mentally simulated past events to judge what caused the outcomes to occur. Participants played a virtual ball‐shooting game and then—while looking at a blank screen—mentally simulated (a) what actually happened, (b) what counterfactually could have happened, or (c) what caused the outcome to happen. Our findings showed (...) that participants moved their eyes in patterns consistent with the actual or counterfactual events that they mentally simulated. When simulating what caused the outcome to occur, participants moved their eyes consistent with simulations of counterfactual possibilities. These results favor counterfactual theories of causal reasoning, demonstrate how eye movements can reflect simulation during this reasoning and provide a novel approach for investigating retrospective causal reasoning and counterfactual thinking.

In contemporary computer simulations, particles attract each other and form clusters, cells interact, and agents communicate with one another. This is at least how computer simulations are commonly described. But how can we make sense of such talk? One answer is that the particles, cells, and agents inside simulations are digital artifacts, and thus real objects. In this paper, I cast doubt on this realist position by raising the question: To what objects does a simulation give rise, if it does (...) so at all? I tentatively suggest answers that try to determine what objects arise in computer simulations at both a fundamental and a higher level. However, closer analysis reveals that we run into underdetermination problems. Even for a single run of a simulation program, the acknowledged facts about the simulations often do not suffice to determine the objects and their properties uniquely. I suggest that, from an ontological perspective, it is more attractive to say that computer simulations involve computations, the results of which may then be interpreted in various ways. To make sense of talk about objects in simulations it is more attractive to develop a fictionalist account, or so I argue. (shrink)

Helicopter cabin noise was simulated by combining a broadband signal (pink noise, or PN) with a triad of pure tones (PT) at 650,1900, and 5000 Hz. Each component was presented at four loudness levels (0,60,70, and 80 dB[A]), with all 16 combinations arranged in two unsystematic orders. Intelligibility was measured by means of sentences to be judged as true or false. A male speaker presented 10 sentences at each noise condition. One group of subjects heard the sentences at 50 dB(A) (...) and another group at 55 dB(A). The annoyance of each noise combination was rated by the same subjects on a 5-point scale. Both sources and their interaction were significantly related to reduced intelligibility and increased annoyance at both speech levels. In general, the PN component was more responsible for loss of intelligibility, and the PT component more responsible for annoyance. (shrink)

A dynamic description model of the flight path a dragonfly takes is required in order to derive the encounter frequency of the dragonfly males visiting a pond. It is considered as the first part of a realistic description of the regulation of dragonfly density at the pond by behavioural interaction. Since the dragonfly males fly strictly along the shoreline of the pond, their displacement may be perceived as a quasi linear movement. The flight paths of dragonflies were recorded in field (...) by registering at regular time intervals the number of the shoreline section. in which the dragonfly was staying at that moment. The recorded flight paths show a wide variety from circling around the pond or flying widely to and fro to remaining in a narrow sector of the shoreline . The records were classified into 9 flight style groups. The flight style is temperature dependent, but there are also individual differences between the dragonflies. The strategy adopted for model building is to start with the most simple assumptions and parameters. The dynamic performance of each model is assessed by simulations. The model has to be extended until the simulated flight path patterns resemble the observed patterns. In a model with one parameter the displacement for every time interval is given by a stochastic decision using the probabilities evaluated from the observed frequencies of step length . This model was run with different sets of data. The simulated patterns using the data from all records together slightly resemble some observed patterns. They represent, however, only a small range of the variability observed. With data from the different style groups or the single records the simulated patterns are much more variable, but they are too irregular and contain too many turns . Therefore the description model was extended by a second parameter determining the direction of each step. The probability of turning is dependent on the number of steps already taken in the same direction . The probabilities are evaluated from the observed frequencies of step series. With the data from all records together, this model yields patterns more similar to the observed flight paths but they still represent only a restricted range of the observed variability. The patterns obtained using the data from the different style groups or from the single records cover the full range of the observed variability and they resemble closely the observed patterns even in minute details . Thus this description model together with the data from the flight style groups is accepted as fully sufficient for the present purpose. The simulations allow the assessment of the range of chance variability . The assumptions implied in the description model were corroborated by statistical tests. The approach developed here for the quantification of the behaviour of dragonflies is generally applicable to stochastic behaviour. Um die Häufigkeit der Kämpfe zwischen Libellenmannchen am Gewässer vom Verhalten der einzelnen Individuen ableiten zu können, wurde ein dynamisches Modell des Flugverhaltens einzelner Libellen aus Freilandbeobachtungen abgeleitet. Das Modell soll ein erster Schritt zu einer realistischen Beschreibung sein, wie bei Libellen die Individuendichte durch Verhaltensinteraktionen geregelt wird. Da die Libellenmannchen streng an der Uferlinie entlang fliegen, kann ihre Flugbahn als quasi eindimensionale Bewegung aufgefaßt werden. Die Flugbahnen einzelner Männchen registrierte ich, indem ich in regelmäßigen Zeitintervallen die Nummer des'Uferabschnitts , in dem sich die Libelle gerade aufhielt, auf Tonband sprach. Die registierten Flugbahnen sind sehr verschiedenartig. Zwischen Bahnen, bei denen die Libellen immer in einer Richtung um das Gewässer kreisten, bis zu solchen, bei denen sie in einem engen Uferbereich hin and her flogen, gibt es alle Übergänge . Die Flugbahnen warden in 9 Gruppen verschiedener Flugstile eingeteilt. Der Flugstil ist temperaturabhängig and individuell verschieden. Die Strategie der Modellentwicklung war, mit einem Modell mit möglichst einfachen Voraussetzungen and Parametern zu beginnen, seine dynamische Leistung mit Simulationen zu prüfen, und die Modellbeschreibung so lange zu erweitern, bis die simulierten Flugbahnmuster den tatsächlich beobachteten Mustern gleichen. Im ersten Modell wurde die Ortsveränderung in jedem Zeitintervall mit einer stochastischen Entscheidung bestimmt, bei der Wahrscheinlichkeiten verwendet warden, die sich aus den beobachteten Haufigkeiten der Schrittweiten ergaben . Simulationen dieses Modells mit den aus allen Flugbahnregistrierungen gemeinsam ausgewerteten Daten ergaben Flugbahnmuster, die zwar manchen beobachteten ähnelten, aber nur einen kleinen Bereich der beobachteten Vielfalt darstellten. Mit den Daten aus den einzelnen Flugstilgruppen ergab sich insgesamt eine grofie Variabilitat, die simulierten Flugbahnen waren aber zu unregelmäßig and enthielten zu viele Richtungswechsel . Deshalb wurde das Modell durch einen Parameter erweitert, der für jedes Zeitintervall die Flugrichtung bestimmt. Die Wahrscheinfchkeit umzukehren hängt davon ab, wieviele Zeitintervalle bereits die gleiche Richtung beibehalten wurde . Die Wahrscheinlichkeitswerte dafür warden aus den beobachteten Haufigkeiten der Schrittserien in eine Richtung bestimmt. Dieses Modell ergibt in Simulationen mit den aus allen Registrierungen gemeinsam ausgewerteten Daten Flugbahnen, die den Originalen ähnlich sind, aber nur einen beschränkten Bereich der vielfalt darstellen. Simulationen mit den Daten aus den einzelnen Flugstilgruppen dagegen ergeben die vollebeobachtete Variabilitat and die erhaltenen Flugbahnmuster gleichen den beobachteten Originalen auch in kleinen Einzelheiten . Dieses Modell kann deshalb zusammen mit den Daten der einzelnen Flugstilgruppen als befriedigende Beschreibung des Flugverhaltens angesehen werden. Die Simulationen erlauben, den Bereich der zufälligen Variabilitat abzuschätzen . Die im Modell gemachten Annahmen warden durch statistische Tests bestätigt. Der hier zur Beschreibung des Verhaltens von Libellen entwickelte Ansatz ist allgemein anwendbar auf stochastisches Verhalten. (shrink)

The stream of human consciousness appears to be interruptible, in that we can experience a sensation of ‘returning to ourselves after an absence of content’ (e.g. sleep, anaesthesia, full-absorption meditation). Prima facie, such evidence poses a challenge to simple applications of theories of consciousness based on electromagnetic or neural activity in the brain, because some of this activity persists during periods of interruption. This paper elaborates one of several possible responses to the challenge. We build on a previous theory in (...) which EM field topology delineates complex macrophenomenal experience. We first apply an analytic lens to identify different ways in which field topologies might generate sensations of ‘absence of content’. We then test the feasibility of a particular phenomenological approach for assessing those field topologies, powered by the unusual lucidity about cessation pathways induced via certain meditation practices and psychedelic dosages. We build computational simulations of these cessation pathways and test them on eight interviewees with various levels of experience in cessation states. We conclude that this approach can generate usable insight, but requires further formalisation to fulfil its potential. The findings tentatively support our claims but the theory remains speculative at this stage. We set out empirical tests with 11 specific predictions, both for further phenomenological research and for brain manipulation research. Although they align neatly, our ontological and cessation theories can also be separated. The paper describes how our theories can be consistent with other perspectives on consciousness, such as variants of predictive processing or global network theory. (shrink)

The notion of empathy has been explicated in different ways in the current debate on how to understand others. Whereas defenders of simulation-based approaches claim that empathy involves some kind of isomorphism between the empathizer’s and the target’s mental state, defenders of the phenomenological account vehemently deny this and claim that empathy allows us to directly perceive someone else’s mental states. Although these views are typically presented as being opposed, I argue that at least one version of a simulation-based approach—the (...) account given by de Vignemont and Jacob—is compatible with the direct-perception view. My argument has two parts: My first step is to show that the conflict between these accounts is not—as it seems at first glance—a disagreement on the mechanism by which empathy comes about. Rather, it is due to the fact that their proponents attribute two very different roles to empathy in understanding others. My second step is to introduce Stein’s account of empathy. By not restricting empathy to either one of these two roles, her process model of empathy helps to see how the divergent intuitions that have been brought forward in the current debate could be integrated.

BackgroundResearch on research integrity has tended to focus on frequency of research misconduct and factors that might induce someone to commit research misconduct. A definitive answer to the first question has been elusive, but it remains clear that any research misconduct is too much. Answers to the second question are so diverse, it might be productive to ask a different question: What about how research is done allows research misconduct to occur?MethodsWith that question in mind, research integrity officers of the (...) 62 members of the American Association of Universities were invited to complete a brief survey about their most recent instance of a finding of research misconduct. Respondents were asked whether one or more good practices of research were present in their case of research misconduct.ResultsTwenty-four of the respondents indicated they had dealt with at least one finding of research misconduct and answered the survey questions. Over half of these RIOs reported that their case of research misconduct had occurred in an environment in which at least nine of the ten listed good practices of research were deficient.ConclusionsThese results are not evidence for a causal effect of poor practices, but it is arguable that committing research misconduct would be more difficult if not impossible in research environments adhering to good practices of research.

In line with some promising studies dealing with particular academic speech events at university level, this article analyses recordings of another established form of spoken academic discourse at university outside the classroom; viz. office hour interactions between faculty and students. Office hour appointments at two German universities were video-recorded and subsequently transcribed according to conventional transcription notations. The study draws upon two levels of analysis. First, a phasal sectioning is performed to highlight different stages in the organization of (...) office hour talk, which are decisive for a fruitful consultation and indispensable to conform to official standards in academia. Concurrently, on an interactional level, findings from conversation analysis are used to display how this form of consultation unfolds, and how participants orient towards both the respective institutional tasks as well as the discourse partner. What becomes clear from this preliminary study is that the academic significance of office hours is often underestimated. Those cases in which complex academic matters are under discussion demand careful action-taking and mutual orientation by both participants. This face-to-face encounter has multiple consequences for the academic and the social relationship between teacher and student, as well as for pedagogical practices and institutional circumstances at large.

Promoting youth representation in parliaments is a growing global priority. To promote youth leadership and more inclusive politics, youth organizations in Nigeria mobilized successfully for a constitutional reform to lower the eligibility age to run for political office. In this paper, we draw on global data to assess whether lower eligibility ages will in fact lead to higher levels of youth participation. We find that lower age requirements positively affect the representation of the youngest and next youngest cohorts in (...) parliament. We draw on qualitative interviews and gender literature to theorize that lower age limits have immediate and longer-term “mobilizing effects”, shifting the calculations of potential candidates in terms of the age at which they first decide to run for office.

Traditional methods of evaluating and solving world problems are insufficient to deal with today's issues, which are complex and interconnected, and therefore cannot be understood, or solved, in isolation. The author's study aimed to better understand behaviors that impact systemic problems in the capacity-building community. The resultant theory of simulating benevolence conceptualizes a collection of behaviors where change agents undertake activities that are not in the best interest of community members. Instead, activities satisfy the need for activity, involvement, and (...) excitement. This theory has real-world implications in the pursuit of systemic social change. In any social context, a change agent cannot merely go through the motions of change, seemingly behaving active and engaged, at the expense of those that he or she claims to help. (shrink)

This paper examines different kinds of definite descriptions denoting purely contingent, necessary or impossible objects. The discourse about contingent/impossible/necessary objects can be organised in terms of rational questions to ask and answer relative to the modal profile of the entity in question. There are also limits on what it is rational to know about entities with this or that modal profile. We will also examine epistemic modalities; they are the kind of necessity and possibility that is determined by _epistemic_ constraints (...) related to knowledge or rationality. Definite descriptions denote so-called _offices_, roles, or _things to be._ We explicate these α-offices as partial functions from possible worlds to chronologies of objects of type α, where α is mostly the type of individuals. Our starting point is Prior’s distinction between a ‘weak’ and ‘strong’ definite article ‘the’. In both cases, the definite description refers to at most one object; yet, in the case of the weak ‘the’, the referred object can change over time, while in the case of the strong ‘the’, the object referred to by the definite description is the same forever, once the office has been occupied. The main result we present is the way how to obtain a Wh-knowledge about who or what plays a given role presented by a hyper-office, i.e. _procedure_ producing an office. Another no less important result concerns the epistemic necessity of the impossibility of knowing who or what occupies the impossible office presented by a hyper-office. (shrink)

With the rapidly growing amounts of information, visualization is becoming increasingly important, as it allows users to easily explore and understand large amounts of information. However the field of information visualiza- tion currently lacks sufficient theoretical foundations. This article addresses foundational questions connecting information visualization with computing and philosophy studies. The idea of multiscale information granula- tion is described based on two fundamental concepts: information (structure) and computation (process). A new information processing paradigm of Granular Computing enables stepwise increase of (...) granulation/aggregation of information on different levels of resolution, which makes possible dynamical viewing of data. Information produced by Google Earth is an illustration of visualization based on clustering (granulation) of information on a succession of layers. Depending on level, specific emergent properties become visible as a result of different ways of aggregation of data/information. As information visualization ultimately aims at amplifying cognition, we discuss the process of simulation and emulation in relation to cognition, and in particular visual cognition. (shrink)

How veridical is perception? Rather than representing objects as they actually exist in the world, might perception instead represent objects only in terms of the utility they offer to an observer? Previous work employed evolutionary modeling to show that under certain assumptions, natural selection favors such “strict‐interface” perceptual systems. This view has fueled considerable debate, but we think that discussions so far have failed to consider the implications of two critical aspects of perception. First, while existing models have explored single (...) utility functions, perception will often serve multiple largely independent goals. (Sometimes when looking at a stick you want to know how appropriate it would be as kindling for a campfire, and other times you want to know how appropriate it would be as a weapon for self‐defense.) Second, perception often operates in an inflexible, automatic manner—proving “impenetrable” to shifting higher‐level goals. (When your goal shifts from “burning” to “fighting,” your visual experience does not dramatically transform.) These two points have important implications for the veridicality of perception. In particular, as the need for flexible goals increases, inflexible perceptual systems must become more veridical. We support this position by providing evidence from evolutionary simulations that as the number of independent utility functions increases, the distinction between “interface” and “veridical” perceptual systems dissolves. Although natural selection evaluates perceptual systems only on their fitness, the most fit perceptual systems may nevertheless represent the world as it is. (shrink)

We analyze the usage of computer simulation at the LHC and derive seven jointly necessary requirements for a simulation to be considered ’trustworthy’, such that it can be used as proxy for experiments. We show that these requirements can also be applied to systems without direct experimental access and discuss their validity for properties that have not yet been probed. While being necessary, these requirements are not sufficient. Such trustworthy simulations will be analyzed for the relative epistemic statuses of simulation (...) and material measurements, from which we argue that claims of their parity are unfounded. Instead, using credibility as a measure for epistemic status, and in view of the temporal and epistemic dependence of simulation on material measurements, we argue that the latter have a higher epistemic status than the former. We further argue that suggestions to qualify the epistemic status by ’defocussing’ on the material connection to the target system of either human or natural experiments are misleading. (shrink)

The thesis of underdetermination presents a major obstacle to the epistemological claims of scientific realism. That thesis is regularly assumed in the philosophy of science, but is puzzlingly at odds with the actual history of science, in which empirically adequate theories are thin on the ground. We propose to advance a case for scientific realism which concentrates on the process of scientific reasoning rather than its theoretical products. Developing an account of causal–explanatory inference will make it easier to resist the (...) thesis of underdetermination. For, if we are not restricted to inference to the best explanation only at the level of major theories, we will be able to acknowledge that there is a structure in data sets which imposes serious constraints on possible theoretical alternatives. We describe how Differential Inference, a form of inference based on contrastive explanation, can be used in order to generate causal hypotheses. We then go on to consider how experimental manipulation of differences can be used to achieve Difference Closure, thereby confirming claims of causal efficacy and also eliminating possible confounds. The model of Differential Inference outlined here shows at least one way in which it is possible to ‘reason from the phenomena’. (shrink)
