When multiple individuals interact in a conversation or as part of a large crowd, emergent structures and dynamics arise that are behavioral properties of the interacting group rather than of any individual member of that group. Recent work using traditional signal processing techniques and machine learning has demonstrated that global acoustic data recorded from a crowd at a basketball game can be used to classify emergent crowd behavior in terms of the crowd's purported emotional state. We propose that the description (...) of crowd behavior from such global acoustic data could benefit from nonlinear analysis methods derived from dynamical systems theory. Such methods have been used in recent research applying nonlinear methods to audio data extracted from music and group musical interactions. In this work, we used nonlinear analyses to extract features that are relevant to the behavioral interactions that underlie acoustic signals produced by a crowd attending a sporting event. We propose that recurrence dynamics measured from these audio signals via recurrence quantification analysis (RQA) reflect information about the behavioral dynamics of the crowd itself. We analyze these dynamics from acoustic signals recorded from crowds attending basketball games, and that were manually labeled according to the crowds' emotional state across six categories: angry noise, applause, cheer, distraction noise, positive chant, and negative chant. We show that RQA measures are useful to differentiate the emergent acoustic behavioral dynamics between these categories, and can provide insight into the recurrence patterns that underlie crowd interactions.

_Rhetoric_ is the sixth volume in The New Hackett Aristotle series, a series featuring translations, with Introductions and Notes, by C. D. C. Reeve, Delta Kappa Epsilon Distinguished Professor of Philosophy at The University of North Carolina at Chapel Hill. The series will eventually include all of Aristotle's works.

"It is... remarkable that Reeve's is the first new English translation since Fowler's Loeb edition of 1926. Fortunately, Reeve has done an excellent job. His version is not slavishly literal but is in general very accurate. It is also very clear and readable. Reeve is particularly to be congratulated for having produced versions of some of the more torturous passages, which are not only faithful to the text but also make good sense in English. The long and detailed introduction is (...) worth reading in its own right." --R. F. Stalley, _The Classical Review_. (shrink)

The demand for female labor is a central explanatory component of macrostructural theories of gender stratification. This study analyzes how the structural demand for female labor affects gender differences in labor force participation. The authors develop a measure of the gendered demand for labor by indexing the degree to which the occupational structure is skewed toward usually male or female occupations. Using census data from 1910 through 1990 and National Longitudinal Sample of Youth data from 261 contemporary U.S. labor markets, (...) the authors show that the gender difference in labor force participation covaries across time and space with this measure of the demand for female labor.

The contemporary astrophysicist today deals with questions that bear on the area known to traditional philosophy as “metaphysics.” Consequently, it is tempting to cross the threshold. One can allow oneself to be tempted by the idea that science is in a position to provide solutions to ancient and venerable metaphysical quests. One can even imagine, according to the wish expressed two thousand years ago by Epicurus, that it can calm our “metaphysical anxieties.”.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.3 (2001) 453-454 [Access article in PDF] Gregory Fried. Heidegger's Polemos: From Being to Politics. New Haven: Yale University Press, 2000. Pp. xvi + 302. Cloth, $35.00. That an outstanding philosopher could align himself with a monstrous ideology has always been a scandalous puzzle: but since Farias's Heidegger and Nazism (1989), it is impossible to dismiss Heidegger's "political episode" as the reprehensible but (...) forgivable lapse of a backwoods academic without political sense. Learning that Heidegger not only was a dedicated Nazi, but engineered a postwar cover-up of his involvement, was for many Heideggereans like entering a beloved office and finding swastikas spraypainted over everything. Consternation has hardly died down in the years since. Philosophers have struggled either to repudiate Heidegger's thought entirely or argue that the parts of it he pledged to Nazism were inconsistent with the rest. It isn't that such people deny (or not out loud) what would seem to be an obvious fact: that a bad man can be a good philosopher. They fear that something in Heidegger's thinking somehow "entails" fascism. A dilemma gets set up: either Heidegger's philosophy is contaminated by his actions, or to engage in those actions, Heidegger must have ignored his philosophy.Fried's book on polemos in Heidegger navigates between these horns: on the one hand, Fried dismisses as "absurd" any simple claim that Heidegger's work entails fascism (5), but on the other hand, he attempts to trace, throughout Heidegger's "middle period" (roughly Being and Time to the end of World War II), a notion he believes is consistent with embracing Nazism, not to argue that Heidegger's political decisions were correct or unavoidable, but that they were predictable—though fatally hubristic—responses to the European situation as Heidegger saw it. More, Fried wants to endorse Heidegger's understanding of polemos as valuable for politics today, not because it is insulated against fascism but because fascism is still a possibility we need to confront, even while we attempt to preserve Enlightenment ideals and liberal-democratic institutions in a "nihilistic" world.Heidegger bases his views about polemos ("struggle," "confrontation") on Heraclitus Fragment 53, where it is called "father and king of all." As he explores Heidegger's [End Page 453] treatment, Fried stresses that "what is of interest is not whether Heidegger's interpretations are philologically correct, but rather how these readings shed light on his own way of making sense of history and of politics" (29). And "confrontation" is the closest thing to a consistent political doctrine in Heidegger. He understands it as a respectful opposition that allows each "side" to appear in all its validity and therefore potential risk to the other "side." Confrontation is a principle of interpretation, dialogue between individuals, and interaction between nations (see 79-80). Fried insists that this idea is a crucial part of a number of central Heideggerean concepts, as well as how Heidegger viewed his own task, and Germany's, when National Socialism appeared with its promise of a new spiritual mission for the German Volk. That Heidegger's "romantic" hopes in Nazism were unfounded does not diminish the usefulness of his work on polemos, Fried thinks, because "postmodernist" thinkers, molded by Heidegger, have nothing better to offer as they "confront" the dying or dead "modern" world with dreams of a new society. Some respect for "liberal" values will still be necessary if postmodernist "deconstruction" of oppressive structures is not to leave inroads for new, opportunistic forms of fascism.Fried's is an important study, by a sympathetic but undazzled scholar of Heidegger, of a concept that may be as basic and fruitful as he claims: but his insistence on making everything in "middle Heidegger" depend on it causes him in many places to conflate separate projects and periods in Heidegger's work that were better left distinct. He is particularly unconvincing when he suggests (e.g., 59, 100, 116) that for Heidegger, human beings can "lose their Dasein" and become "unbeings" to whom "Being is... (shrink)

Aristotle on Practical Wisdom is the first full-scale commentary on Nicomachean Ethics VI to be issued in a century, and the most illuminating ever. A meticulous translation with facing-page analysis enables readers to engage directly with Aristotle's account, while the lucid introduction locates it in the context of his—and later—ethical thought.

Professor Bonnie Steinbock writes ‘… I am not going to discuss rights, important as the issue is’; but she adds, en passant , ‘According to the view of rights held by H. L. A. Hart and S. I. Benn, infants do not have rights, nor do the mentally defective, nor do the insane, in so far as they all lack certain minimal conceptual capabilities for having rights’.

Celem tego artykułu jest krótka analiza republikańskiej koncepcji wolności przedstawianej w polskiej i pozapolskiej teorii republikańskiej XVI wieku. Punktem wyjścia rozważań jest teza głosząca, że kategoria wolności w teorii republikańskiej jest ściśle związana z namysłem i ustaleniami dotyczącymi istoty i celu wspólnoty politycznej, określanej w tradycji rzymskiej mianem civitas libera. Wolność jest pochodną dobrze urządzonego, wolnego ładu politycznego, w którym kluczową rolę odgrywa prawo i cnota. Analizując ideę wolności republikańskiej przez pryzmat dwóch kontekstów: klasycznej tradycji republikańskiej i jej ustaleń oraz (...) ładu społeczno-ustrojowego Rzeczypospolitej, wskazuję, że łączy się ona ściśle z innymi kluczowymi dla teorii republikańskiej kategoriami, takimi jak res publica, sprawiedliwość i prawo, cnota, ustrój mieszany oraz obywatelskość, wyrażana w ideale vita activa, i dopiero w połączeniu z nimi możliwe jest ukazanie pełnego rozumienia wolności i jej uwarunkowań.

Mr William Charlton ) quotes Russell on Motion. It has been pointed out to me that the book referred to in line 5 as Principles of Philosophy should in all probability be The Principles of Mathematics , and on looking into the matter I find that this is indeed the case. On p. 473 of the latter book I read: 447. It is to be observed that … we must entirely reject the notion of a state of motion. Motion consists (...) merely in the occupation of different places at different times, subject to continuity as explained in Part V. (shrink)

Sir Francis Galton writes: “Those who find a difficulty in understanding how a feebly felt mental action can vanquish a strong desire, will find the difficulty vanish if they consent to assume a physiological and not a psychical standpoint. The gain is as great as viewing the planetary system after the fashion of Copernicus, instead of that of Ptolemy. There is nothing contrary to experience in supposing that conflicting physiological actions may be perceived with a distinctness quite disproportionate to their (...) real efficacy. We may compare the conflict between faintly perceived activities of one kind and clearly perceived activities of another kind, to that between troops dressed in a uniform scarcely distinguishable from the background with others clad in staring scarlet. We must be content to admit that our consciousness has a very inexact cognisance of the physiological battles in our brain, and that the mystery why apparently weak motives of one class should invariably get the better of apparently strong motives of another class, lies wholly in the word ‘apparently’. In short, that the appearances of their relative strength are deceptive”. (shrink)

We show that true colors as defined by Chevreul (1839) produce unsuspected simultaneous brightness induction effects on their immediate grey backgrounds when these are placed on a darker (black) general background surrounding two spatially separated configurations. Assimilation and apparent contrast may occur in one and the same stimulus display. We examined the possible link between these effects and the perceived depth of the color patterns which induce them as a function of their luminance contrast. Patterns of square-shaped inducers of a (...) single color (red, green, blue, yellow, or grey) were placed on background fields of a lighter and a darker grey, presented on a darker screen. Inducers were always darker on one side of the display and brighter on the other in a given trial. The intensity of the grey backgrounds varied between trials only. This permitted generating four inducer luminance contrasts, presented in random order, for each color. Background fields were either spatially separated or consisted of a single grey field on the black screen. Experiments were run under three environmental conditions: dark-adaptation, daylight, and rod-saturation after exposure to bright light. In a first task, we measured probabilities of contrast, assimilation, and no effect in a three-alternative forced-choice procedure (background appears brighter on the ‘left’, on the ‘right’ or the ‘same’). Visual adaptation and inducer contrast had no significant influence on the induction effects produced by colored inducers. Achromatic inducers produced significantly stronger contrast effects after dark-adaptation, and significantly stronger assimilation in daylight conditions. Grouping two backgrounds into a single one was found to significantly decrease probabilities of apparent contrast. Under the same conditions, we measured probabilities of the inducers to be perceived as nearer to the observer inducers. These, as predicted by Chevreul’s law of contrast, were determined by the luminance contrast of the inducers only, with significantly higher probabilities of brighter inducers to be seen as nearer, and a marked asymmetry between effects produced by inducers of opposite sign. Implications of these findings for theories which attempt to link simultaneous induction effects to the relative depth of object surfaces in the visual field are discussed. (shrink)

Poorly saturated colors are closer to a pure grey than strongly saturated ones and, therefore, appear less “colorful”. Color saturation is effectively manipulated in the visual arts for balancing conflicting sensations and moods and for inducing the perception of relative distance in the pictorial plane. While perceptual science has proven quite clearly that the luminance contrast of any hue acts as a self-sufficient cue to relative depth in visual images, the role of color saturation in such figure-ground organization has remained (...) unclear. We presented configurations of colored inducers on grey ‘test’ backgrounds to human observers. Luminance and saturation of the inducers was uniform on each trial, but varied across trials. We ran two separate experimental tasks. In the relative background brightness task, perceptual judgments indicated whether the apparent brightness of the grey test background contrasted with, assimilated to, or appeared equal (no effect) to that of a comparison background with the same luminance contrast. Contrast polarity and its interaction with color saturation affected response proportions for contrast, assimilation and no effect. In the figure-ground task, perceptual judgments indicated whether the inducers appeared to lie in front of, behind, or in the same depth with the background. Strongly saturated inducers produced significantly larger proportions of foreground effects indicating that these inducers stand out as figure against the background. Weakly saturated inducers produced significantly larger proportions of background effects, indicating that these inducers are perceived as lying behind the backgrounds. We infer that color saturation modulates figure-ground organization, both directly by determining relative inducer depth, and indirectly, and in interaction with contrast polarity, by affecting apparent background brightness. The results point towards a hitherto undocumented functional role of color saturation in the genesis of form, and in particular figure-ground percepts in the absence of chromatostereopsis. (shrink)

This new translation of _On Coming to Be and Passing Away _and_ Meteorology 1 and 4_ fits seamlessly with the other volumes in the New Hackett Aristotle Series, enabling Anglophone readers to study these works in a way previously not possible. The Introduction describes the book that lies ahead, explaining what it is about, what it is trying to do, how it goes about doing it, and what sort of audience it presupposes. Sequentially numbered, cross-referenced endnotes provide the information most (...) needed at each juncture, while a detailed Index indicates the places where focused discussion of key notions occurs.

The laws which predict how the perceptual quality of figure-ground can be extracted from the most elementary visual signals were discovered by the Gestaltists, and form an essential part of their movement (see especially Metzger, 1930, and Wertheimer, 1923 translated and re-edited by Lothar Spillmann, 2009 and 2012, respectively). Distinguishing figure from ground is a prerequisite for perception of both form and space (the relative positions, trajectories, and distances of objects in the visual field. The human brain has an astonishing (...) capacity for selecting and combining a few critical visual signals to accurately represent both form and space. (shrink)

The critical examination of current hypotheses is one of the key ways in which scientific fields develop and grow. Therefore, any critique, including Haidle and Schlaudt’s article, “Where Does Cumulative Culture Begin? A Plea for a Sociologically Informed Perspective,” represents a welcome addition to the literature. However, critiques must also be evaluated. In their article, Haidle and Schlaudt review some approaches to culture and cumulative culture in both human and nonhuman primates. H&S discuss the “zone of latent solutions” hypothesis as (...) applied to nonhuman primates and stone-toolmaking premodern hominins. Here, we will evaluate whether H&S’s critique addresses its target. (shrink)

Organizations have long struggled to find ways to reduce the occurrence of unethical behaviors by employees. Unfortunately, time theft, a common and costly form of ethical misconduct at work, has been understudied by ethics researchers. In order to remedy this gap in the literature, we used the theory of planned behavior (TPB) to investigate the antecedents of time theft, which includes behaviors such as arriving later to or leaving earlier from work than scheduled, taking additional or longer breaks than is (...) acceptable, and on-the-job daydreaming. We surveyed 135 employed undergraduate business students regarding the TPB variables at Time 1. Two months later, participants reported the frequency they engaged in time theft since Time 1. Results indicate that behavioral, normative, and control beliefs significantly predicted attitudes, subjective norms, and perceived behavioral control, respectively. Attitudes, subjective norms, and perceived behavioral control, in turn, were significantly related to time theft intentions, which predicted later enactment of time theft. Thus, employers can decrease time theft by primarily focusing on altering employees’ attitudes toward time theft, followed by reducing social pressures to engage in it, and lastly, by implementing organizational practices that make it difficult to commit time theft.

The first part of the paper introduces the varieties of modern constructive mathematics, concentrating on Bishop's constructive mathematics (BISH). it gives a sketch of both Myhill's axiomatic system for BISH and a constructive axiomatic development of the real line R. The second part of the paper focusses on the relation between constructive mathematics and programming, with emphasis on Martin-L6f 's theory of types as a formal system for BISH.

Originally published in 1989 Liberal Neutrality approaches the recommendation of neutrality by confronting the abstract prescription (that we should be neutral) with the implications for particular people and institutions. This not only identifies what neutrality involves logically, but also exposes the practical difficulties that may be encountered in pursuing it. In some cases, such close examination shows that neutrality is not desirable, and in others that it is attainable only within certain limits. Although neutrality has become a fashionable term in (...) political theory, this is the only volume to subject the idea to systematic scrutiny. It will be useful not only to specialists in diverse disciplines - political scientists, philosophers, sociologists, lawyers and educationalists. (shrink)

Victor Vasarely's (1906–1997) important legacy to the study of human perception is brought to the forefront and discussed. A large part of his impressive work conveys the appearance of striking three-dimensional shapes and structures in a large-scale pictorial plane. Current perception science explains such effects by invoking brain mechanisms for the processing of monocular (2D) depth cues. Here in this study, we illustrate and explain local effects of 2D color and contrast cues on the perceptual organization in terms of figure-ground (...) assignments, i.e. which local surfaces are likely to be seen as “nearer” or “bigger” in the image plane. Paired configurations are embedded in a larger, structurally ambivalent pictorial context inspired by some of Vasarely's creations. The figure-ground effects these configurations produce reveal a significant correlation between perceptual solutions for “nearer” and “bigger” when other geometric depth cues are missing. In consistency with previous findings on similar, albeit simpler visual displays, a specific color may compete with luminance contrast to resolve the planar ambiguity of a complex pattern context at a critical point in the hierarchical resolution of figure-ground uncertainty. The potential role of color temperature in this process is brought forward here. Vasarely intuitively understood and successfully exploited the subtle context effects accounted for in this paper, well before empirical investigation had set out to study and explain them in terms of information processing by the visual brain.

In this study, we test whether children whose culture lacks CWs and counting practices use a spatial strategy to support enumeration tasks. Children from two indigenous communities in Australia whose native and only language (Warlpiri or Anindilyakwa) lacked CWs and were tested on classical number development tasks, and the results were compared with those of children reared in an English-speaking environment. We found that Warlpiri- and Anindilyakwa-speaking children performed equivalently to their English-speaking counterparts. However, in tasks in which they were (...) required to match the number of objects in a display, they were more likely to reconstruct part or all of the spatial arrangement of the target than were their English-speaking counterparts. Following John Locke's interpretation of users of similar American languages and in contrast with later Whorfian interpretations, we suggest that CWs may be strategically useful, but that in their absence, other task-specific strategies will be deployed.

This is the first of a series of papers devoted to the thorough investigation of refinement based on an underlying partial relational model. In this paper we restrict attention to operation refinement. We explore four theories of refinement based on an underlying partial relation model for specifications, and we show that they are all equivalent. This, in particular, sheds some light on the relational completion operator due to Woodcock which underlies data refinement in, for example, the specification language Z. It (...) further leads to two simple alternative models which are also equivalent to the others. (shrink)

Technology has expanded genomic research and the complexity of extracted gene-related information. Health-related genomic incidental findings pose new dilemmas for nurse researchers regarding the ethical application of disclosure to participants. Consequently, informed consent specific to incidental findings is recommended. Critical Social Theory is used as a guide in recognition of the changing meaning of informed consent and to serve as a framework to inform nursing of the ethical application of disclosure consent in genomic nursing research practices.

The current debate regarding the suitability of anencephalics as organ donors is due primarily to misunderstandings. The anatomical and neurophysiological literature shows that the anencephalic lacks a cerebrum because of the failure of neuralplate fusion. However, even the incomplete function of an atrophic brain stem is currently accepted at law in most if not all countries as sufficient for brain life: which is to say, cessation of breathing is currently required in order to make the diagnosis of brain death. Because (...) of the extensive incompleteness of the anencephalic's brain, it is not possible to postpone death significantly by mechanical ventilation and intravenous feeding. It is acceptable to maintain life for a short period of time in order to allow organ transplantation subsequent to the declaration of death at the point of cessation of the capacity for spontaneous respiration. The most important issue is not transplantation, but the issue of brain life raised by the case of anencephalics. Since brain life in any significant sense begins only after the closure of the neural tube on the 30th day after conception, it is reasonable to take this as the point at which brain life begins. Laws should be amended in all countries to allow the abortion of anencephalics at any time, in that they do not at any time possess brain life. (shrink)
