The divergence point analysis procedure is aimed at obtaining an estimate of the onset of the influence of an experimental variable on response latencies (e.g., fixation duration, reaction time). The procedure involves generating survival curves for two conditions, and using a bootstrapping technique to estimate the timing of the earliest discernible divergence between curves. In the present paper, several key extensions for this procedure were proposed and evaluated by conducting simulations and by reanalyzing data from previous (...) studies. Our findings indicate that the modified versions of the procedure performed substantially better than the original procedure under conditions of low experimental power. Furthermore, unlike the original procedure, the modified procedures provided divergence point estimates for individual participants and permitted testing the significance of the difference between estimates across conditions. The advantages of the modified procedures are illustrated, the theoretical and methodological implications are discussed, and promising future directions are outlined. (shrink)

Jensen’s inequality is one of the fundamental inequalities which has several applications in almost every field of science. In 2003, Mercer gave a variant of Jensen’s inequality which is known as Jensen–Mercer’s inequality. The purpose of this article is to propose new bounds for Csiszár and related divergences by means of Jensen–Mercer’s inequality. Also, we investigate several new bounds for Zipf–Mandelbrot entropy. The idea of this article may further stimulate research on information theory with the help of Jensen–Mercer’s inequality.

In this paper, we propose the model averaging estimation method for multiplicative error model and construct the corresponding weight choosing criterion based on the Kullback–Leibler divergence with a hyperparameter to avoid the problem of overfitting. The resulting model average estimator is proved to be asymptotically optimal. It is shown that the Kullback–Leibler model averaging estimator asymptotically minimizes the in-sample Kullback–Leibler divergence and improves the forecast accuracy of out-of-sample even under different loss functions. In simulations, we show that the (...) KLMA estimator compares favorably with smooth-AIC estimator, smooth-BIC estimator, and Mallows model averaging estimator, especially when some nonlinear noise is added to the data generation process. The empirical applications in the daily range of S&P500 and price duration of IBM show that the out-of-sample forecasting capacity of the KLMA estimator is better than that of other methods.

Philosophers of biology have worked extensively on how we ought best to interpret the probabilities which arise throughout evolutionary theory. In spite of this substantial work, however, much of the debate has remained persistently intractable. I offer the example of Bayesian models of divergence time estimation as a case study in how we might bring further resources from the biological literature to bear on these debates. These models offer us an example in which a number of different sources of (...) uncertainty are combined to produce an estimate for a complex, unobservable quantity. These models have been carefully analyzed in recent biological work, which has determined the relationship between these sources of uncertainty, both quantitatively and qualitatively. I suggest here that this case shows us the limitations of univocal analyses of probability in evolution, as well as the simple dichotomy between “subjective” and “objective” probabilities, and I conclude by gesturing toward ways in which we might introduce more sophisticated interpretive taxonomies of probability as a path toward advancing debates on probability in the life sciences.

We describe a dual-process theory of how individuals estimate the probabilities of unique events, such as Hillary Clinton becoming U.S. President. It postulates that uncertainty is a guide to improbability. In its computer implementation, an intuitive system 1 simulates evidence in mental models and forms analog non-numerical representations of the magnitude of degrees of belief. This system has minimal computational power and combines evidence using a small repertoire of primitive operations. It resolves the uncertainty of divergent evidence for single (...) events, for conjunctions of events, and for inclusive disjunctions of events, by taking a primitive average of non-numerical probabilities. It computes conditional probabilities in a tractable way, treating the given event as evidence that may be relevant to the probability of the dependent event. A deliberative system 2 maps the resulting representations into numerical probabilities. With access to working memory, it carries out arithmetical operations in combining numerical estimates. Experiments corroborated the theory's predictions. Participants concurred in estimates of real possibilities. They violated the complete joint probability distribution in the predicted ways, when they made estimates about conjunctions: P, P, P, disjunctions: P, P, P, and conditional probabilities P, P, P. They were faster to estimate the probabilities of compound propositions when they had already estimated the probabilities of each of their components. We discuss the implications of these results for theories of probabilistic reasoning. (shrink)

Do participants bring their own priors to an experiment? If so, do they share the same priors as the researchers who design the experiment? In this article, we examine the extent to which self-generated priors conform to experimenters’ expectations by explicitly asking participants to indicate their own priors in estimating the probability of a variety of events. We find in Study 1 that despite being instructed to follow a uniform distribution, participants appear to have used their own priors, which deviated (...) from the given instructions. Using subjects’ own priors allows us to account better for their responses rather than merely to test the accuracy of their estimates. Implications for the study of judgment and decision making are discussed. (shrink)

Cephalopods are extraordinary molluscs equipped with vertebrate‐like intelligence and a unique buoyancy system for locomotion. A growing body of evidence from the fossil record, embryology and Bayesian molecular divergence estimations provides a comprehensive picture of their origins and evolution. Cephalopods evolved during the Cambrian (∼530 Ma) from a monoplacophoran‐like mollusc in which the conical, external shell was modified into a chambered buoyancy apparatus. During the mid‐Palaeozoic (∼416 Ma) cephalopods diverged into nautiloids and the presently dominant coleoids. Coleoids (i.e. squids, (...) cuttlefish and octopods) internalised their shells and, in the late Palaeozoic (∼276 Ma), diverged into Vampyropoda and the Decabrachia. This shell internalisation appears to be a unique evolutionary event. In contrast, the loss of a mineralised shell has occurred several times in distinct coleoid lineages. The general tendency of shell reduction reflects a trend towards active modes of life and much more complex behaviour. (shrink)

Segmentation of post-operative glioblastoma multiforme (GBM) is essential for the planning of Tumor Treating Fields (TTFields) treatment and other clinical applications. Recent methods developed for pre-operative GBM segmentation perform poorly on post-operative GBM MRI scans. In this paper we present a method for the segmentation of GBM in post-operative patients. Our method incorporates an ensemble of segmentation networks and the Kullback–Leibler divergence agreement score in the objective function to estimate the prediction label uncertainty and cope with noisy labels (...) and inter-observer variability. Moreover, our method integrates the surgery type and computes non-tumorous tissue delineation to automatically segment the tumor. We trained and validated our method on a dataset of 340 enhanced T1 MRI scans of patients that were treated with TTFields (270 scans for train and 70 scans for test). For validation, we developed a tool that uses the uncertainty map along with the segmentation result. Our tool allows visualization and fast editing of the tissues to improve the results dependent on user preference. Three physicians reviewed and graded our segmentation and editing tool on 12 different MRI scans. The validation set average (SD) Dice scores were 0.81 (0.11), 0.71 (0.24), 0.64 (0.25), and 0.68 (0.19) for whole-tumor, resection, necrotic-core, and enhancing-tissue, respectively. The physicians rated 72% of the segmented GBMs acceptable for treatment planning or better. Another 22% can be edited manually in a reasonable time to achieve a clinically acceptable result. According to these results, the proposed method for GBM segmentation can be integrated into TTFields treatment planning software in order to shorten the planning process. To conclude, we have extended a state-of-the-art pre-operative GBM segmentation method with surgery-type, anatomical information, and uncertainty visualization to facilitate a clinically viable segmentation of post-operative GBM for TTFields treatment planning.

Unsupervised learning techniques, e.g. clustering, is useful for obtaining a summary of a dataset. However, its application to large databases can be computationally expensive. Alternatively, useful information can also be retrieved from its subsets in a more efficient yet effective manner. This paper addresses the problem of finding a small subset of minority instances whose distribution significantly differs from that of the majority. Generally, such a subset can substantially overlap with the majority, which is problematic for conventional estimation of distribution. (...) This paper proposes a new approach for estimating a minority distribution based on Information Theoretic Framework, an extension of the Rate Distortion Theory for unsupervised learning tasks. Specifically, the proposed method estimates parameters which maximize the divergence between the minority and majority distributions, penalizes the redundancy of data expression based on the mutual information between the observed and hidden variables, and employs a hard assignment approximation to avoid computation of trivial conditional probabilities. The algorithm of the proposed method has no problem-dependent parameter and its time and space complexities are linear to the size of the minority subset. Experiments using artificial datasets show the proposed method yields significantly high precision and sensitivity in detecting minority subsets which substantially overlaps with the majority. The proposed method also substantially outperforms one-class classification and mixture estimation methods in real-world benchmark datasets for text and satellite imagery classification. (shrink)

This study examined the effects of mood and risk-taking on divergent and convergent thinking using a Q-learning computation model. The results revealed that while mood was not significantly related to divergent or convergent thinking (as creative thinking types), risk-taking exerted positive effects on divergent thinking in the face of negative rewards. The results were consistent with the representational change theory in insight problem solving. Although this theory accounts directly for insight, the underlying idea of going beyond current contexts and implicit (...) constrains could be applied to creative thinking as well. The results indeed accounted for the relevance of this theory to divergent thinking. The current study is one of the first empirical studies simultaneously examining the role of mood and risk-taking in creativity. In particular, no related studies exist that took a computational approach to estimate the relevant parameters in the framework of dynamic optimization. Our Q learning model enables to distinguish and identify the different roles of mood and risk-taking in updatingQvalues and making decisions. (shrink)

Fisher’s 1918 paper accomplished two distinct goals: unifying discrete Mendelian genetics with continuous biometric phenotypes and quantifying the variance components of variation in complex human characteristics. The former contributed to the foundation of modern quantitative genetics; the latter was adopted by social scientists interested in the pursuit of Galtonian nature-nurture questions about the biological and social origins of human behavior, especially human intelligence. This historical divergence has produced competing notions of the estimation of variance ratios referred to as heritability. (...) Jay Lush showed that they could be applied to selective breeding on the farm, while the early twin geneticists used them as a descriptive statistic to describe the degree of genetic determination in complex human traits. Here we trace the early history of the heritability coefficient now used by social scientists. (shrink)

I explain the difficulty of making various concepts of and relating to probability precise, rigorous and physically significant when attempting to apply them in reasoning about objects living in infinite-dimensional spaces, working through many examples from cosmology. I focus on the relation of topological to measure-theoretic notions of and relating to probability, how they diverge in unpleasant ways in the infinite-dimensional case, and are even difficult to work with on their own. Even in cases where an appropriate family of spacetimes (...) is finite-dimensional, and so admits a measure of the relevant sort, however, it is always the case that the family is not a compact topological space, and so does not admit a physically significant, well behaved probability measure. Problems of a different but still deeply troubling sort plague arguments about likelihood in that context, which I also discuss. I conclude that most standard forms of argument used in cosmology to estimate the likelihood of the occurrence of various properties or behaviors of spacetimes have serious mathematical, physical and conceptual problems.

Risk communication poses a challenge to ordinary norms of truth-telling because it can easily mislead. Analyzing this challenge in terms of a systematic divergence between expertise and public attitudes fails to recognize how two specific features of the concept of risk play a role in managing daily affairs. First, evaluating risk always incorporates an estimate of the reliability of information. Since risk communication is an effort at providing information, audiences will naturally and appropriately incorporate their assessment of the (...) reliability of the risk communicator into their assessment of the risk as such. Second, one conceptual and grammatical feature of the concept of risk is to categorize experience as non-routine and demanding further deliberation. That is, the whole point of calling something a risk can be to distinguish it from activities or phenomena that need no further attention. Risk communications that stress relative comparisons of measured probabilities and expected utilities can be inconsistent with both features of our concept of risk. At best they mislead; at worst they undermine our society’s capacity to cope with risk. While there are no simple answers to these two conundrums, technical experts should bear them in mind when communicating with the broader public. (shrink)

We investigated whether inconsistencies in previous studies regarding emotional experiences in dreams derive from whether dream emotions are self-rated or externally evaluated. Seventeen subjects were monitored with polysomnography in the sleep laboratory and awakened from every rapid eye movement sleep stage 5 min after the onset of the stage. Upon awakening, participants gave an oral dream report and rated their dream emotions using the modified Differential Emotions Scale, whereas external judges rated the participants’ emotions expressed in the dream reports, using (...) the same scale. The two approaches produced diverging results. Self-ratings, as compared to external ratings, resulted in greater estimates of emotional dreams; positively valenced dreams; positive and negative emotions per dream; and various discrete emotions represented in dreams. The results suggest that this is mostly due to the underrepresentation of positive emotions in dream reports. Possible reasons for this discrepancy are discussed. (shrink)

The focus of this paper is to discuss the semiotic aspects of our findings from a project we conducted in the frame of Emotional Text Analysis paradigm. In the project, we intended to create a computer text classifier capable of effectively classifying texts into emotional categories. We agreed that we would need discrete data samples to input into it. For this, we asked 178 informants to give a verdict on the dominant emotion of 48 sample texts. Prior to their assessment (...) of the texts, the informants responded to a questionnaire used to estimate their empathic tendency. A detailed analysis of the informants’ assessments and personal empathetic tendency scores showed a positive correlation. Subsequently, our interest was piqued by the issue of how emotions could be triggered by conventional signs. Our findings seem to suggest that words are only used as an expression form insofar as they embody another type of semiotic complexity, thus diverging from the traditional Pearcian triad. In order to develop on these findings, it is therefore the main objective of this paper to provide a biosemiotic model of representation/interpretation of emotions, with particular attention paid to the eliciting of emotions as sign types. In this endeavour, we draw upon K. Kull’s concept of emonic semiotic model realization. Our suggestion is that, when one processes a text that elicits an emotional response, two semiotic facets are relevant: indexicality and emonicity. We argue that it is a main empathetic function to enforce the emonic model of semiosis over the indexical in situations where the interpreter has a choice between the two. As such, the hypothesis of the study is that emotions facilitate a particular type of semiotic mechanism, relying on the mimesis principle. (shrink)

Statements such as “X is beautiful but I don’t like how it looks” or “I like how X looks but it is not beautiful” sound contradictory. How contradictory they sound might however depend on the object X and on the aesthetic adjective being used (“beautiful”, “elegant”, “dynamic”, etc.). In our study, the first sentence was estimated to be more contradictory than the latter: If we describe something as beautiful, we often intend to evaluate its appearance, whereas it is less counterintuitive (...) to appreciate an appearance without finding it beautiful. Furthermore, statements including “beautiful” appeared more contradictory than those including “elegant” and “dynamic”, pointing to its greater evaluative component. When related to artworks, sentences could appear less contradictory due to readers’ consideration of the divergence between conventional beauty and art-related sensory pleasures that can even include negative valence. Such ambivalence might be more frequent in art-objects than in other artefacts. Indeed, in our study, sentences referring to artworks were estimated to be less contradictory compared to sentences referring to other artefacts. Meanwhile, an additional small group of graphic design students showed a less clear difference between art-related and non-art-related sentences. We discuss the potential influence of art experience and interest as well as theoretical and methodological challenges like the conceptualization of beauty. (shrink)

There is no cure or vaccine for HIV/AIDS. The only life-prolonging treatment available is antiretroviral (ARV) therapy. WHO estimates, however, that less than 5 percent of those who require treatment in developing countries currently enjoy access to these medicines. In Africa fewer than 50,000 people–less than 2 percent of the people in need–currently receive ARV therapy. These facts have elicited strongly divergent reactions, and views about the appropriate response to this crisis have varied widely.The intensity of the debate concerning access (...) to life-prolonging medicines for the treatment of HIV/AIDS, and the heated rhetoric with which they are often conducted, suggest that these disagreements may be rooted in deeper disagreements of value. It is not obvious, however, what disagreements of value are at stake in this debate. By analyzing the statements of scholars, public officials, activist organizations, and private sector representatives, each of whom may endorse very different policy recommendations on access to HIV/AIDS drugs, we have identified and created a typology of the different sources of disagreement in the debate. We conclude that the central disagreements concerning access to medicines arise from competing understandings of how responsibilities for bringing remedy to hardships should be allocated to different agents and institutions. A central lesson that emerges from our analysis is that thinking about “health equity” must extend beyond the explanation and justification of goals, values, and ideals, and engage more honestly with the difficult question of how responsibilities for bringing remedy to health crises should be allocated in complex social contexts.

Prospect Theory (PT) is widely regarded as the most promising descriptive model for decision making under uncertainty. Various tests have corroborated the validity of the characteristic fourfold pattern of risk attitudes implied by the combination of probability weighting and value transformation. But is it also safe to assume stable PT preferences at the individual level? This is not only an empirical but also a conceptual question. Measuring the stability of preferences in a multi-parameter decision model such as PT is far (...) more complex than evaluating single-parameter models such as Expected Utility Theory under the assumption of constant relative risk aversion. There exist considerable interdependencies among parameters such that allegedly diverging parameter combinations could in fact produce very similar preference structures. In this paper, we provide a theoretic framework for measuring the (temporal) stability of PT parameters. To illustrate our methodology, we further apply our approach to 86 subjects for whom we elicit PT parameters twice, with a time lag of 1 month. While documenting remarkable stability of parameter estimates at the aggregate level, we find that a third of the subjects show significant instability across sessions. (shrink)

Human infection challenge studies provide illuminating case studies for several ongoing debates in research ethics, including those related to research risks and payment of participants. Grimwade et al 1 add to previous public engagement, qualitative evidence and philosophical literature on these topics.1–8 The authors advocate revision of research payment policy and practice based on their main finding that members of the public endorse ex ante payment of participants proportional to research-related risk exposure, in addition to post hoc compensation for any (...) lasting harms that occur.1 Although ‘payment for risk’ would diverge from most current research ethics guidelines, it is noteworthy that the difference in payment to participants that their framework would allow might only be small, at least in the case of currently accepted studies. The absolute difference would likely be small because the risk of currently accepted HCS participation is usually very low.9 10 On a ‘value of statistical life’ approach, mirroring actuarial accounting for fatal risks, a 1 in 100 000 risk of death might attract an extra payment of only US$96.1 Most HCS do not involve fatality risks this high, although, on pessimistic estimates, the risk of COVID-19 HCS in young healthy adults might involve similar levels of risk.11 Such risks might arguably be justified by large expected public health benefits,12,9 11 13 but it remains controversial whether higher levels of payment could ….

Previous discussions of the evolution of the self have diverged greatly in their estimates of the date at which the capacity for self-thought emerged, the factors that led self-reflection to evolve, and the nature of the evidence offered to support these disparate conclusions. Beginning with the assumption that human self-awareness involves a set of distinct cognitive abilities that evolved at different times to solve different adaptive problems, we trace the evolution of self-awareness from the common ancestor of humans and apes (...) to the beginnings of culture, drawing upon paleontological, anthropological, biological, and psychological evidence. These data converge to suggest that that modern self-thought appeared just prior to the Middle-Upper Paleolithic transition, approximately 60,000 years ago.Recto running head: Evolution of the Self.

Background Consent policies for post-mortem organ procurement (OP) vary throughout Europe, and yet no studies have empirically evaluated the ethical implications of contrasting consent models. To fill this gap, we introduce a novel indicator of governance quality based on the ideal of informed support, and examine national differences on this measure through a quantitative survey of OP policy informedness and preferences in seven European countries. -/- Methods Between 2017–2019, we conducted a convenience sample survey of students (n = 2006) in (...) Austria (AT), Belgium (BE), Denmark (DK), Germany (DE), Greece (GR), Slovenia (SI) and Spain (ES), asking participants about their donation preferences, as well as their beliefs and views about the policy in place. From these measures, we computed indices of informedness, policy support, and fulfilment of unexpressed preferences, which we compared across countries and consent systems. -/- Results Our study introduces a tool for analyzing policy governance in the context of OP. Wide variation in policy awareness was observed: Most respondents in DK, DE, AT and BE correctly identified the policy in place, while those in SI, GR and ES did not. Respondents in opt-out countries (AT, BE, ES and GR) tended to support the policy in place (with one exception, i.e., SI), whereas those in opt-in countries (DE and DK) overwhelmingly opposed it. These results reveal stark differences in governance quality across countries and consent policies: We found a preponderance of informed opposition in opt-in countries and a general tendency towards support–either informed or uninformed–in opt-out countries. We also found informed divergence in opt-in countries and a tendency for convergence–either informed or uninformed–among opt-out countries. -/- Conclusion Our study offers a novel tool for analyzing governance quality and illustrates, in the context of OP, how the strengths and weaknesses of different policy implementations can be estimated and compared using quantitative survey data.

CELL AND PSYCHE THE BIOLOGY OF PURPOSE By EDMUND W. SINNOTT. PREFACE TO THE TORCHBOOK EDITION: SINCE the publication of this little book, as the McNair Lectures at the University of North Carolina, the author has written two others, as well as a number of papers, on the same gen eral theme. Though these elaborate the argument a little further, the essence of it is in Cell and Psyche. This is admittedly a specula tion, but one based solidly on biological (...) fact. It has been regarded as rather visionary and metaphysical by some people, but others have been attracted to it by the suggestion it offers for a better understanding of the ancient problem of how mind and body are related to each other. This problem is of such paramount impor tance, not only for a knowledge of what man really is but for the construction of a satisfying life philosophy, that any light thrown on it should be welcome. The suggestion that man's physical life grows out of the basic goal-seeking and purposiveness found in all organic behavior and that this, in turn, is an aspect of the more general self - regulating and normative character evident in the development and activities of living organisms, is at least worth serious consideration. If we are to avoid a dualistic idea of man's nature and to construct a true monism that does not require the sacrifice of the significance of either mind or body, some such conception as this seems a rea sonable means of doing so. It is to be hoped that the wider distri bution now made possible for the present book may result in a more general consideration of this particular relationship between biol ogy and philosophy* E. W.

INTRODUCTION: IN THE CLAMOR and confusion of our times one fact grows ever clearer beliefs are important. One of the major problems with which men now are faced per haps, indeed, the most important one is the wide dis agreement which still exists in their fundamental philos ophies. What course a man will follow, or a nation, is set in no small measure by his basic creed, by what he really thinks about the true nature of a human being his personality, his freedom, his destiny, his relations to others and to the rest of the universe; by the judgments lie makes as to what qualities and courses of action are admirable and should command his allegiance. These are not academic questions merely. They arc ancient mys teries which long have troubled human hearts and seem today almost as far as ever from solution. The answer a ny* n gives to them is the most significant thing that one can know about him. We may be tempted to under estimate the importance of these inner directives and turn instead to outer influences, to economic and social factors, as more decisive for our actions. But when we look at what the philosophy of Marx has done to set one half the world against the other, at the basic divergence between the thinking of East and West, and at so many other differences in political and religious beliefs which now divide mankind, we can hardly doubt the profound practical import of men's philosophies. It is still true today that as a man thinketh in his heart, so is he. In the minds of men are the most fateful battles fought. Against those ideologies we condemn, force in the end will fail. If our opponents cannot be convinced, or their ideas reconci. (shrink)

In the first part of this paper, I shall argue that Apollodorus of Athens, in his Chronica, dated Anaxagoras' arrival at Athens to 456/5, following Demetrius of Phalerum. Rejecting the divergent opinion of others, he also followed Demetrius' estimation of the Athenian period as having lasted 20 years, which makes 437/6 Anaxagoras' last year at Athens 1). In the second part I shall argue that the trial of Anaxagoras, about which no information survives in the remains of Apollodorus but which (...) is reported by several other sources, should probably be dated to 437/6. This second argument is independent of the first; both run counter to the view, still rather popular among historians of ancient philosophy, which favours a date for the trial either immediately preceding or even following upon the beginning of the Peloponnesian War, as well as to the communis opinio according to which the Athenian period lasted 30 years. What is common to both parts of this inquiry is a refusal to study the chronology of Anaxagoras' career in isolation. In part I, which is chiefly concerned with an analysis of the relevant passage in Diogenes Laertius qua specimen of Apollodorean reasoning, the problem is discussed against the background of Apollodorus' synchronistic matrices. In part II, the trial and the decree of Diopeithes which made it possible are studied in connection with the plot against Pericles and certain members of his circle.-A suggestion regarding the date of 'publication' of Anaxagoras' treatise will be appended to part II.

Intraspecific niche variation can differentially impact community processes and can represent the initial stages of adaptive radiation. Here we test for intraspecific differences in niche use in a keystone species, the alewife (Alosa pseudoharengus). To test whether feedbacks between predator foraging traits and prey communities have led to differences in niche use, we compare the diet composition and trophic position of anadromous and landlocked alewife populations. These populations differ in phenotypic traits related to foraging (gill raker spacing, gape width, and (...) prey selectivity). Trait differences appear to have resulted from eco-evolutionary feedbacks between alewives and their zooplankton prey, and suggest that these two life history forms are exploiting different niches. Direct diets show that anadromous alewives consume a greater biomass of predatory copepods than do landlocked alewives. Anadromous alewives also consume more ostracods—a littoral prey item—as the growing season progresses. These diet differences do not translate into a significant difference in trophic position, as estimated from stable isotopes. However, stable-isotope estimates of diet source show that during early fall, anadromous alewives obtain significantly more of their dietary carbon from the littoral food web. This increased reliance on littoral prey is likely a result of a diet switch that occurs in response to the alewife-driven exhaustion of large-bodied prey items available in the pelagic zone, i.e., alewife niche construction. These findings show the existence of important intraspecific niche differences in the alewife and support the role of eco-evolutionary feedbacks in shaping these niche differences. The initiation of alewife divergence is the result of dam building by humans. Therefore, alewife niche differentiation can be considered to be an eco-evolutionary byproduct of human cultural niche construction. (shrink)

Many ethical concerns have been voiced about Clinical Decision Support Systems (CDSSs). Special attention has been paid to the effect of CDSSs on autonomy, responsibility, fairness and transparency. This journal has featured a discussion between Rosalind McDougall and Ezio Di Nucci that focused on the impact of IBM’s Watson for Oncology (Watson) on autonomy. The present article elaborates on this discussion in three ways. First, using Jonathan Pugh’s account of rational autonomy we show that how Watson presents its results might (...) impact decisional autonomy, while how Watson produces knowledge might affect practical autonomy. Second, by drawing an analogy with patient decision aids we identify an empirical way of estimating Watson’s impact on autonomy (ie, value-congruence). Lastly, McDougall introduced the notion of value-flexible design as a way to account for the diverging preferences patients hold. We will clarify its relation with the established domain of value-sensitive design. In terms of the tripartite methodology of value-sensitive design, we offer aconceptualclarification using Pugh’s account of rational autonomy, anempiricaltool to evaluate Watson’s impact on autonomy and situate a group oftechnicaloptions to incorporate autonomy in Watson’s design.

One of the major effects of prohibiting or inhibiting explicit evaluation is to forestall the exhibition and obviate the possible acknowledgment of divergent systems of value and thus to ratify, by default, established evaluative authority. It is worth noting that in none of the debates of the forties and fifties was the traditional academic canon itself questioned, and that where evaluative authority was not ringingly affirmed, asserted, or self-justified, it was simply assumed. Thus Frye himself could speak almost in one (...) breath of the need to “get rid of…all casual, sentimental, and prejudiced value-judgments” as “the first step in developing a genuine poetics” and of “the masterpieces of literature” which are “the materials of literary criticism” . The identity of those masterpieces, it seemed, could be taken for granted or followed more or less automatically from the “direct value-judgment of informed good taste” or “certain literary values…fully established by critical experience” .In a passage of particular interest, Frye wrote:Comparative estimates of value are really inferences, most valid when silent ones, from critical practice…The critic will find soon, and constantly, that Milton is a more rewarding and suggestive poet than Blackmore. But the more obvious this becomes, the less time he will want to waste belaboring the point. [AC, p. 25]In addition to the noteworthy correlation of validity with silence , two other aspects of Frye’s remarks here repay some attention. First, in claiming that it is altogether obvious that Milton, rather than Blackmore, is “a more rewarding and suggestive poet [for the critic] to work with,” Frye begged the question of what kind of work the critic would be doing. For surely if one were concerned with a question such as the relation of canonical and noncanonical texts in the system of literary value in eighteenth-century England, one would find Blackmore just as rewarding and suggestive to work with as Milton. Both here and in his repeated insistence that the “material” of criticism must be “the masterpieces of literature” , Frye exhibits a severely limited conception of the potential domain of literary study and of the sort of problems and phenomena with which it could or should deal. In this conceptual and methodological confinement, however , he has been joined by just about every other member of the Anglo-American literary academy during the past fifty years. Barbara Herrnstein Smith is University Professor of English and communications and director of the Center for the Study of Art and Symbolic Behavior at the University of Pennsylvania. She is the author of, among other works, Poetic Closure and On the Margins of Discourse. Her previous contribution to Critical Inquiry, “Narrative Versions, Narrative Theories,” appeared in the Autumn 1980 issue.

People often face preferential decisions under risk. To further our understanding of the cognitive processes underlying these preferential choices, two prominent cognitive models, decision field theory (DFT; Busemeyer & Townsend, 1993) and the proportional difference model (PD; González‐Vallejo, 2002), were rigorously tested against each other. In two consecutive experiments, the participants repeatedly had to choose between monetary gambles. The first experiment provided the reference to estimate the models’ free parameters. From these estimations, new gamble pairs were generated for the (...) second experiment such that the two models made maximally divergent predictions. In the first experiment, both models explained the data equally well. However, in the second generalization experiment, the participants’ choices were much closer to the predictions of DFT. The results indicate that the stochastic process assumed by DFT, in which evidence in favor of or against each option accumulates over time, described people’s choice behavior better than the trade‐offs between proportional differences assumed by PD.

The discoveries, advancements and continuing controversies in the field of molecular evolution are reviewed. Topics summarized are (1) the evolution of the genetic code, (2) gene evolution including the demonstration of homology, estimation of sequence divergence, phylogenetic trees, the molecular clock and the origin of genes and gene families by various genetic mechanisms, and (3) eukaryotic genome evolution, including the highly repeated satellite sequences, the interspersed and potentially mobile repeated sequences and the unique sequence fraction of the genome.

It is well known that the self-energy of the gauge bosons is quadratically divergent in the Standard Model when a simple cutoff is imposed. We demonstrate phenomenologically that the quadratic divergences in fact unify. The unification occurs at a surprisingly low scale, \(\Lambda _\mathrm {u}\approx 4\times 10^7\) GeV. Suppose now that there is a spontaneously broken rotational symmetry between the space-time coordinates and gauge theoretical phases. The symmetry-breaking pattern is such that the gauge bosons arise as the massless Goldstone bosons, (...) whereas the dilatonic mode acts as the massive (Higgs) boson, whose vacuum expectation value determines the gauge couplings. In this case, the quadratic divergences or the tadpoles of the gauge boson self-energy should indeed unify because these divergences need to be cancelled by a universal dilatonic contribution, assuming dynamical symmetry breaking. If there is dynamical symmetry breaking, we are in principle able to calculate the value of the gauge couplings as well as the scale hierarchy \(\Lambda _\mathrm {cut}/\Lambda _\mathrm {u}\) . We perform this calculation by adopting a naive quartic symmetry-breaking potential which unfortunately violates local gauge invariance. Using tadpole-cancellation and dilatonic self-energy conditions, the value of \(\Lambda _\mathrm {cut}\) is then found to be approximately \(4\times 10^{18}\) GeV in the Feynman gauge and \(5\times 10^{15}\) GeV in the Landau gauge. The cancellation of an anomaly in the dilaton self-energy requires that the number of fermionic generations equals three. The symmetry-breaking needs to be driven by some other mass-generating mechanism such as electroweak symmetry breaking. Our estimation for \(\Lambda _\mathrm {u}\) is of the correct order if \(\Lambda _\mathrm {cut}\approx 5\times 10^{15}\) GeV. (shrink)

In the general problem of verisimilitude, we try to define the distance of a statement from a target, which is an informative truth about some domain of investigation. For example, the target can be a state description, a structure description, or a constituent of a first-order language. In the problem of legisimilitude, the target is a deterministic or universal law, which can be expressed by a nomic constituent or a quantitative function involving the operators of physical necessity and possibility. The (...) special case of legisimilitude, where the target is a probabilistic law, has been discussed by Roger Rosenkrantz and Ilkka Niiniluoto. Their basic proposal is to measure the distance between two probabilistic laws by the Kullback–Leibler notion of divergence, which is a semimetric on the space of probability measures. This idea can be applied to probabilistic laws of coexistence and laws of succession, and the examples may involve discrete or continuous state spaces. In this paper, these earlier studies are elaborated in four directions. First, even though deterministic laws are limiting cases of probabilistic laws, the target-sensitivity of truthlikeness measures implies that the legisimilitude of probabilistic laws is not easily reducible to the deterministic case. Secondly, the Jensen-Shannon divergence is applied to mixed probabilistic laws which entail some universal laws. Thirdly, a new class of distance measures between probability distributions is proposed, so that their horizontal differences are taken into account in addition to vertical ones. Fourthly, a solution is given for the epistemic problem of estimating degrees of probabilistic legisimilitude on the basis of empirical evidence. (shrink)

This article argues that annual hours per employed person and per working-age person capture important dimensions of political-economic success that should be weighed against aggregate employment and wealth patterns. It also argues that partisan-driven work-time policies and welfare-regime institutions give rise to diverging Social Democratic, Liberal, and Christian Democratic “worlds” of work time in terms of these two measures. Descriptive statistics for eighteen Organization for Economic Cooperation and Development countries reveal broad clustering and trends suggestive of the Three Worlds, while (...) panel estimation suggests the influence of partisan and welfare-institutional conditions underlying them. Case study of Finland, the United States, and the Netherlands further illustrates the political process and sequence of the Three Worlds. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Michael Murray THE CONFLICT BETWEEN POETRY AND LITERATURE While Heidegger, Gadamer, and Ricoeur are widely regarded as engaged in a common hermeneutic enterprise, the greater radicality of Heidegger must fracture such a view. This difference shows up in a striking manner in the conflict between the concept of poetry and the concept of literature. After elucidating its significance, I shall explore a new sense of fiction that reinscribes the (...) conflict and invites us to interpret a canto of Wallace Stevens. Let us enter Gadamer's dispute with Heidegger where he declares: "It is true... I can appeal to the 'transcendental' sense of Heidegger's Being and Time. But where else I call on Heidegger — in that I seek to think 'understanding" as a 'happening7 — [my thought] is turned in an entirely different direction." That direction, Gadamer goes on to explain, arose "out ofthe need for self-clarification that came over me as a philologist and interpreter of philosophical texts." To which he adds trenchantly: "My point of departure is not the complete forgetfulness of Being, the 'night of Being,' rather on the contrary — I say this against Heidegger as well as Buber— the unreality of such an assertion. That also holds good for our relation to the tradition." ' This last statement is directed against the encompassing project of Heidegger's later work, his epochal history ofBeing from Anaximander to Nietzsche. This ontological history or aletheia process is charted in terms of the figure of day and night that come so easily in German where the West is das Abendland. Heidegger hyphenates this name (Abend-land) in order to bring forward its status as land of the evening. The historical 59 60Philosophy and Literature evening in question points us back toward the dawn of the West in early Greek thought, poetry, and life, and to its second weaker beginning in the Classical period, and thence ahead to die darkening ofthe modern world, marked by the flight of the gods, the destruction of the earth, the massification of man, and the resentment of the creative — a darkening that has passed into its night and approaches its midnight now in the age of the Gestell or total framework. As such this time betokens the possibility of a second dawn nourished by the memory of the first, though it cannot be a return. Elsewhere Heidegger elaborates this late modern situation in Hölderlinian terms as the Age between the No Longer and the Not Yet. What is thought by the time of die Between and by the language of the lighting-concealing history-of-Being is, according to Heidegger, what really specifies the hermeneutic situation of modern man, poetry, and society. While Gadamer accepts the nineteenth- and twentieth-century discovery ofhistoricity, and tries to advance insights of Heidegger along with his own to clarify the conditions of humanistic knowledge, he rejects the consummative eschatology of Hegel but no less the catastrophic eschatology of Heidegger. As he emphatically declares: "I do not believe at all that we live Tietween' two worlds.... Only the prophet who already sees the promised land would have, in my estimation, the possibility of saying the like. I remember, instead of this, the one world I only know, and which in all decay has lost far less of its evidence and cohesion than it talks itselfinto."2 Of course Heidegger himself insists upon a relation to tradition, reiterated in the asseveration of his later years "that everything essential, everything great arises from man's rootedness in his homeland and tradition."3 Nevertheless, one must say that the revolutionary renewal of Heidegger that presupposes the revolutionary break is not the renewal for which Gadamer speaks. To Ulustrate this divergence of Gadamer from Heidegger we may ponder the concept of the classic. This example occupies an important place in the argument of Truth and Method because the experience of the classic is recognized as combining a genuine historical efficaciousness with a normative significance in the formation of the Western literary tradition (TM, pp. 253ff). In a more recent paper Gadamer explains die "peculiar contemporaneity" that accrues to classic works of literature by reason of tiieir Wirkungsgeschichte or effective-history.* First, they occupy "a...

Because the traditional social media fuzzy static image interactive three-dimensional (3D) reconstruction method has the problem of poor reconstruction completeness and long reconstruction time, the social media fuzzy static image interactive 3D reconstruction method is proposed. For preprocessing the fuzzy static image of social media, the Harris corner detection method is used to extract the feature points of the preprocessed fuzzy static image of social media. According to the extraction results, the parameter estimation algorithm of contrast divergence is used (...) to learn the restricted Boltzmann machine (RBM) network model, and the RBM network model is divided into input, output, and hidden layers. By combining the RBM-based joint dictionary learning method and a sparse representation model, an interactive 3D reconstruction of fuzzy static images in social media is achieved. Experimental results based on the CAD software show that the proposed method has a reconstruction completeness of above 95% and the reconstruction time is less than 15 s, improving the completeness and efficiency of the reconstruction, effectively reconstructing the fuzzy static images in social media, and increasing the sense of reality of social media images.

Historically, taxonomy, which is the area responsible for describing new species, used a priori only morphological characteristics. Darwin already pointed out that there was a great divergence among taxonomists when they classified some organism as a species. When a new species is described, due to its historical weight, the morphological characters are considered as the first species demarcation criterion, however, with the advance of genetics and molecular biology, new methods are added. The use of multiple methods seems to be (...) necessary for us to develop a contemporary taxonomy, so, a little more than a decade ago, the “integrative taxonomy” emerged, which refers to a taxonomy that aims to integrate all available data sources to frame the data. species limits. Data integration is not possible, as we do not have the technological capacity to do so. In view of this, we can interact the data through interactive taxonomy, which suggests, a way of treating the data under the assumption of different lines of evidence, through which the explanations have logical consequences that can be tested, mitigating the subjectivity of the subject in the process. Data interactions can overlap taxonomic descriptions, as they could encompass different phenomena and problem solving, thereby mitigating subjectivism. Therefore, in different fields, at least two indications would be necessary, which could be contained in two different approaches, one hypothetical and one by estimation. Such interpellations would contain evidence with different assumptions and dissimilar data characteristics, thus increasing the number of evidence, as well as improving the reliability of the argument. In this way, we can bring new species to light with a more objective bias and with less likelihood of error. Keywords: Taxonomy. Cryptic species. Estimation. Hypothetical. (shrink)

I I set out my view that all inference is essentially deductive and pinpoint what I take to be the major shortcomings of the induction rule.II The import of data depends on the probability model of the experiment, a dependence ignored by the induction rule. Inductivists admit background knowledge must be taken into account but never spell out how this is to be done. As I see it, that is the problem of induction.III The induction rule, far from providing a (...) method of discovery, does not even serve to detect pattern. Knowing that there is uniformity in the universe is no help to discovering laws. A critique of Reichenbach's justification of the straight rule is constructed along these lines.IV The induction rule, by itself, cannot account for the varying rates at which confidence in an hypothesis mounts with data. The mathematical analysis of this salient feature of inductive reasoning requires prior probabilities. We also argue, against orthodox statisticians, that prior probabilities make a substantive contribution to the objectivity of inductive methods, viz. to the design of experiments and the selection of decision rules.V Carnap's general criticisms of various estimation rules, like the straight rule and the ‘impervious rule’, are seen to be misguided when the prior densities to which they correspond are taken into account.VI Analysis of Hempel's definition of confirmation qua formalization of the enumerative (naive) conception of instancehood. We show that from the standpoint of the quantitative measure P(H/E):P(H) for the degree to which E confirms H, Hempel's classificatory concept yields correct results only for sampling at large from a finite population with a two-way classification all of whose compositions are equally probable. We extend the analysis to Goodman's paradox, finding cases in which grue-like hypotheses do receive as much confirmation as their opposite numbers. We argue, moreover, the irrelevancy of entrenchment, and maintain that Goodman's paradox is no more than a straightforward counter-example to the enumerative conception of instancehood embodied in Hempel's definition.VII We rebutt the objection that prior probabilities, qua inputs of Bayesian analysis, can only be obtained by enumerative induction (insofar as they are objective). The divergence in the prior densities of two rational agents is less a function of subjectivity, we maintain, than of vagueness.VIII Our concluding remarks stress that, for Bayesians, there is no problem of induction in the usual sense.

This chapter first considers the estimates of how great the contribution of the Pythagoreans was to Plato's philosophy and how these views diverge substantially, and which vary across the range from ‘decisive’ to ‘insignificant’. It shows that Platonists were characterized by a benevolent attitude to Pythagoras and the Pythagoreans and an interest in their scientific, philosophical, and religious theories. Number doctrine is found in the testimonies of all three Platonists, but there is in them no picture of a Pythagorean philosophy (...) even remotely reminiscent of number doctrine. The Platonists reacted, not to a common Pythagorean doctrine, but to various theories of Pythagoras and his successors: Philolaus, Archytas, Ecphantus and Hicetas, et al. The chapter then considers Aristotle's reports on the Pythagoreans in his surviving works. (shrink)

"friends" stress the liberal and republican basis ofhis teaching. This debate between good and the evil in Machiavelli's teaching has accompanied the conflict on the tyrannical and the republican character of his work ever since.4 While the essence of his prescriptions continues to be contested, most interpreters concur on Machiavelli 's realism or political pragmatism defined in The Prince 25 as effectual 1 I am grateful to Anthony J. Parel, Arpad Szakolczai, and AdolfTrägler for comments on an earlier draft of this essay. 2Perhaps with the exception of Marx who shares with Machiavelli the heritage of an inflationary and contentious scholarship. Despite this resemblance, there are fundamental differences when it comes to declare oneself a follower of Machiavelli or follower of Marx. See Aron (256-259). 3In his extensive overview, Berlin estimates the totality of the bibliography at more than 3,000 titles. Needless to say that is has considerably increased since then. The recent wave of new translations into English (Mansfield and Tarcov, or Codevilla) and several new approaches provide for the richness of debate. This debate sometimes acquires a heated intensity, such as in the exchange on Strauss's Machiavelli between Mansfield and Pocock in Political Theory, 3:4 (1975), 372-405. 4See for a recent update the introduction to a new translation ofthe Discourses in Mansfield and Tarcov. Harald Wydra37 truth (verità ejfetuale). In this stress on factual reality as opposed to imagination many have seen the sources of Machiavelli's advocacy of technicity, rationality and reason of state. Such a viewpoint is supported by Machiavelli's pure and emotionless style ofwriting. Machiavelli's effectual truth is essentially about the mastery over conflict and contingency in politics. Yet, there are hardly systematic studies on the status and role ofpolitical conflict and its consequences for political order in Machiavelli's work.5 Most classical studies include analysis of conflict (Pocock; Lefort; Sasso), but they do so by sticking to the natural textual division ofhis major works. This article sets out to elaborate some guidelines ofa Machiavellian theory ofconflict by linking it to René Girard's theory of mimetic conflict. It aims to achieve two things: first, to analyze the nature of political conflict in Machiavelli's work. Second, to reexamine some widespread assumption on the autonomy of politics. The Affinity of Machiavelli and Girard: Crisis and Conflict Methodologically, a reading ofMachiavelli through Girard has a status different from that of orthodox comparisons oftwo thinkers.6 This can be illustrated by considering Raymond Aron's comparison between Machiavelli and Marx. On the one hand, Machiavelli's political philosophy is marked by a stress on cyclical repetition and permanent instability. His realism maintains that the more things change the more they remain the same. On the other hand, Marx's economic philosophy of history envisages long-term progress and as such reflects upon change by its confidence in Providence. Yet, essentially both works are concerned with the contingent modalities of collective conflict over time. While for Machiavelli the struggle for power unfolds between political groups such as nobles and the people, Marx suggests the social and economic roots ofconflicts in social formations. Against this background, a reading of Machiavelli through Girard diverges from conventional comparisons. Machiavelli's work emanates from his experience as a practitioner ofpolitics who aims to be the counsellor of Princes. A trained historian and literary critic, Girard analyzes fundamental 5To my knowledge, by far the most balanced and detailed treatment is given by Sasso.

La lecture de Newton joue un rôle décisif dans l’élaboration par Hegel et par Schelling de leur « philosophie de la nature », et dans leur manière de définir le rapport de la philosophie aux sciences positives. Hegel et Schelling, à partir d’un constat initial commun (Newton aurait fait malgré lui de la métaphysique, bien qu’il ait voulu s’en garder) développent deux lectures tout à fait divergentes. Hegel estime que Newton aurait dû s’en tenir au refus de la métaphysique. Schelling (...) au contraire regrette que Newton n’ait pas davantage pris conscience du nécessaire enracinement des concepts scientifiques dans des catégories métaphysiques. Nous tentons de montrer que cette divergence s’enracine dans un débat, lancé par Newton lui-même, sur le caractère réel ou conventionnel des forces décrites par la physique moderne. Cette analyse conduit à souligner un paradoxe : alors que Hegel développe une épistémologie très favorable au travail des sciences positives, il prend une position radicalement hostile aux conséquences philosophiques de la révolution galiléenne et newtonienne, Schelling quant à lui, développe à la fois une épistémologie méfiante vis-à-vis de l’indépendance des sciences positives, et une vision très moderne de la structure de l’univers, du statut des forces et de la définition de la matière. La place du temps naturel dans les systèmes de Hegel et de Schelling pourra ainsi être clarifiée. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reflections on Jewish and Christian Encounters with BuddhismHarold KasimowA thousand years hence, historians will look back at the twentieth century and remember it not for the struggle between Liberalism and Communism but for the momentous human discovery of the encounter between Christianity and Buddhism.—Arnold ToynbeeBeginning in the 1960s many American Jews and Christians have become fascinated with the Buddhist tradition and have immersed themselves in the study and practice (...) of Buddhism. In this presentation I will examine how Christian and Jewish leaders have responded to this phenomenon. Some have been quite suspicious of such interreligious and cross-cultural encounters, claiming that Buddhism is a great threat to their religions. However, others have argued that their encounters with Buddhism have led them to deeper insight into their own traditions and have helped them to become better human beings. Their practice of Buddhist meditation has been a way for them to develop sensitivity to God and greater commitment to their own traditions. Still others have converted to Buddhism; it is estimated that of the three million Buddhists in America, fully one million are converts from Christianity and Judaism.Because of the complexity and diversity within Judaism, Christianity, and Buddhism, I will focus on the responses of leading Orthodox Jews and Roman Catholic Christians to Theravada Buddhism and to the Zen school in Mahayana, the two forms of Buddhism to which many Americans are drawn and with which I have some personal experience. I will first examine how members of the Jewish and Christian traditions view other religions, because an individual’s perception of the encounter is shaped by how their religion views the Buddhist tradition. This will help us understand why religious authorities find this fascination with Buddhism so problematic.the jewish-buddhist encounterHistorically, Judaism has largely been interpreted by its thinkers as the only true religion. However, this does not mean that members of other faiths may not attain [End Page 21] salvation. According to the Talmudic Doctrine of the Seven Commandments of the Sons of Noah, “the righteous of all nations have a share in the world to come,” that is, all human beings can attain salvation who establish courts of law and who refrain from idolatry, murder, blasphemy against God, incest, theft, and eating the limb of a live animal. Jewish authorities claim that because Christianity and Islam worship God they are not to be considered idolatrous, although some question the monotheistic nature of Christianity because of the doctrine of the Trinity and the Incarnation. However, there is no question that members of Asian religions are practicing idolatrous worship, avodah zarah (“strange worship”). They are therefore in violation of the Noahide Law not to worship idols.With some exceptions, Orthodox rabbis in recent times agree with Rabbi Avigdor Miller (1908–2001) that “Buddhism, Shintoism, and all other religions of the Far East are forms of idol worship.”1 For Rabbi Miller the Torah contains all the knowledge that is necessary for Jews, and to even study another religious tradition is an affront to God. That this attitude toward the study of alien texts is common today is evident from the reaction of Rabbi Chaim Zvi Hollander to the suggestion of Rabbi Zalman Schachter that it is permissible to explore Asian forms of spirituality. Hollander charges that “Zalman Schachter’s incredible advice is a direct contradiction of the Almighty’s request that we not seek out and explore the spiritual modes of the Goyim, even if it is for the purpose of enhancing our spiritual experience in the service of our God.”2 He further states that “the practice of any religion other than Judaism is for a Jew an act of Avoda Zara.”3For Rabbis Miller and Hollander, blending Judaism with the Buddhist tradition, which is not concerned with a creator God and which rejects the idea of self, is inconceivable and more dangerous than Jews who convert to another religious tradition. However, even among the Orthodox, there are divergent views. Irving Greenberg, one of the outstanding liberal Orthodox rabbis of our generation, after meeting with the Dalai Lama wrote, “the Dalai Lama taught us a lot about Buddhism, even more about menschlichkeit...

This paper studies the properties and performance of models for estimating local probability distributions which are used as components of larger probabilistic systems — history-based generative parsing models. We report experimental results showing that memory-based learning outperforms many commonly used methods for this task (Witten-Bell, Jelinek-Mercer with fixed weights, decision trees, and log-linear models). However, we can connect these results with the commonly used general class of deleted interpolation models by showing that certain types of memory-based learning, including the kind (...) that performed so well in our experiments, are instances of this class. In addition, we illustrate the divergences between joint and conditional data likelihood and accuracy performance achieved by such models, suggesting that smoothing based on optimizing accuracy directError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMaply might greatly improve performance.

In the current efforts of harmonizing the standards and enforcement of IPRs protection worldwide, this paper explores software piracy trajectories and dynamics in Africa. Using a battery of estimation techniques that ignore as well as integrate short-run disturbances in time-dynamic fashion, we answer the big questions policy makers are most likely to ask before harmonizing IPRs regimes in the battle against software piracy. Three main findings are established. (1) African countries with low software piracy rates are catching-up their counterparts with (...) higher rates; implying despite existing divergent IPRs systems, convergence in piracy rate could be a genuine standard-setting platform. (2) Legal origins do not play a very significant role in the convergence process. (3) A genuine timeframe for standardizing IPRs laws in the fight against piracy is most likely between a horizon of 4–8 years. In other words, full (100 %) convergence within the specified horizon will mean the enforcements of IPRs regimes without distinction of nationality and locality. Policy implications and caveats are discussed. (shrink)

We report two issues concerning diverging sets of Bayesian (conditional) probabilities-divergence of "posteriors"-that can result with increasing evidence. Consider a set P of probabilities typically, but not always, based on a set of Bayesian "priors." Fix E, an event of interest, and X, a random variable to be observed. With respect to P, when the set of conditional probabilities for E, given X, strictly contains the set of unconditional probabilities for E, for each possible outcome X = x, call (...) this phenomenon dilation of the set of probabilities (Seidenfeld and Wasserman 1993). Thus, dilation contrasts with the asymptotic merging of posterior probabilities reported by Savage (1954) and by Blackwell and Dubins (1962). (1) In a wide variety of models for Robust Bayesian inference the extent to which X dilates E is related to a model specific index of how far key elements of P are from a distribution that makes X and E independent. (2) At a fixed confidence level, (1-α), Classical interval estimates A n for, e.g., a Normal mean θ have length O(n -1/2 ) (for sample size n). Of course, the confidence level correctly reports the (prior) probability that θ ∈ A n ,P(A n )=1-α , independent of the prior for θ . However, as shown by Pericchi and Walley (1991), if an ε -contamination class is used for the prior on the parameter θ , there is asymptotic (posterior) dilation for the A n , given the data. If, however, the intervals A ′ n are chosen with length $O(\sqrt{\log (\text{n})/\text{n})}$ , then there is no asymptotic dilation. We discuss the asymptotic rates of dilation for ClassClassical and Bayesian interval estimates and relate these to Bayesian hypothesis testing. (shrink)

We examined the relationship between political affiliation, perceptual estimates, and subjective judgements of disease prevalence and mortality across three chart types. An online survey exposed separate groups of participants to charts displaying COVID-19 data or COVID-19 data labeled ‘Influenza ’. Block 1 examined responses to cross-sectional mortality data ; results revealed that perceptual estimates comparing mortality in two countries were similar across political affiliations and chart types, while subjective judgements revealed a disease x political party interaction. Although Democrats and Republicans (...) provided similar proportion estimates, Democrats interpreted mortality to be higher than Republicans; Democrats also interpreted mortality to be higher for COVID-19 than Influenza. Block 2 examined responses to time series ; Democrats and Republicans estimated greater slopes for COVID-19 trend lines than Influenza lines ; subjective judgements revealed a disease x political party interaction. Democrats and Republicans indicated similar subjective rates of change for COVID-19 trends, and Democrats indicated lower subjective rates of change for Influenza than in any other condition. Thus, while Democrats and Republicans saw the graphs similarly in terms of percentages and line slopes, their subjective interpretations diverged. While we may see graphs of infectious disease data similarly from a purely mathematical or geometric perspective, our political affiliations may moderate how we subjectively interpret the data.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Reading David Hume’s “Of the Standard of Taste.” ed. by Babette BabichTina BaceskiBabette Babich, ed. Reading David Hume’s “Of the Standard of Taste.” Berlin: deGruyter, 2020. Pp. VII + 333. ISBN: 978-3-11-058564-3, paper, $24.99.Reading David Hume’s “Of the Standard of Taste,” a volume of essays edited by Babette Babich, purports to offer the reader a “collective stud[y]” of Hume’s famous essay and its related concerns. Almost all the (...) contributions have previously been published, either as journal articles or book chapters. “Of the Standard of Taste” is helpfully included at the beginning of the volume, though Hume Studies readers will already be familiar with the text. The book is divided into five parts. The editor’s introduction comprises part I. Hume’s essay makes up the entirety of part II. Parts III–V are organized around different general themes, with each part containing from three to five essays. In total the book contains twelve essays.Hume’s “Of the Standard of Taste” is a “classic” work in aesthetics today, but what entitles it to this appellation? Indeed, why do we judge any work to be of “classical value?” “Taste” plays a central role in evaluations of this sort, particularly the “taste” of modern scholars. But, as Hume knew, the historical sensibilities of judges are liable to change over the years, and so “some things that appear in their day to be sure classics, things that have until then withstood the test of time, can undergo a shift in value for another era” (13). In her Introduction, Babich tells an engaging, if not always easy to follow, story about Hume’s “deathbed readings” to illustrate the point. From final conversations with Adam Smith, we know that Hume was reading Lucian’s Dialogues of the Dead. But which of Lucian’s several such dialogues was he reading? When the question was put to Annette Baier (who was at that time herself writing about Hume and “last things”), she confessed to being puzzled by the very [End Page 341] question (6). Baier’s initial puzzlement and subsequent investigations to resolve this confusion revealed just how much her own sensibilities diverged from those of Hume’s day. Babich observes: “[T]he Lucian who was popular in Hume’s own day and even through to the beginning of the twentieth century, has today so diminished in “classical” value that he is sufficiently esoteric that Hume scholars like Baier have trouble tracking him down” (13). My own initial confusions reading the Introduction are likely attributable, in part, to the fact that I, too, was unfamiliar with Lucian. Ironically, this fact is, itself, further evidence of Babich’s point: yesterday’s literary gems have dimmed in value today because modern scholars are not conversant with their works. I have already ordered my copy of Lucian.The book’s rationale is explained as follows: “The entire concern of this volume is all about the critical basis for such claims [which works have “classical” value]. How can we determine a standard for estimating tomorrow’s likely classic, whether in the literary domain or other areas where taste plays a role” (14)? There is more at stake with respect to Hume’s “Of the Standard of Taste,” however, than merely predicting “literary futures.” The question concerning a standard of taste has important consequences for improving judgments in a much wider arena: art more broadly (painting, architecture, sculpture, etc.), but perhaps also science and even economics, to mention but a few. Only one of the essays collected here takes up the topic of “classical value” and “literary futures” per se: the editor’s own. The reader is left to make out what they can from the various contributions. But the essays can all advance the discussion insofar as each one attempts to shed light on an important related concern, e.g., the nature of taste, the nature of a standard, influences on taste, and so on. In what follows, I will offer a brief account of some of the essays in parts III–V, so the reader can get an overall flavor (taste) of the volume.Part III... (shrink)

The article concerns the main lines of reception of the philosophical ideas of B. Spinoza. Estimates of the work of this thinker, his role and importance have undergone significant changes in the course of the development of Western European and Russian philosophical thought. It focuses on the study of the transformations occurred in the approach and nature of evaluations of the main philosophical ideas of Spinoza in the Western European philosophical space, primarily in Germany and France. At the same time, (...) we can state that the peak of interest in the philosophy of Spinoza in these national traditions seriously diverges in time. Initially, we can talk about the predominance of interest in Spinoza’s philosophy on the part of German-speaking thinkers. For a long time, Spinoza’s philosophy was characterized as atheistic and, in connection with this, was subjected to fierce criticism. It is the German enlighteners who are credited with reviving interest in Spinoza’s philosophy at a new level. At the same time, the philosophical views of this thinker not only cease to be assessed as atheistic, but are sometimes perceived in the exact opposite way - as imbued with genuine religious faith. F. Schleiermacher can be considered here as a striking example of such an approach to Spinoza’s philosophy. In the future, interest in Spinoza’s philosophy was maintained in the German-speaking philosophical space due to the reception of his ideas by Hegel, Feuerbach, and Neo-Kantians. In French-language philosophy, interest in Spinoza wakes up much later - in the middle-second half of the 20th century, which is associated primarily with such name as Deleuze. However, this “French Renaissance” of Spinoza’s philosophy can be considered as no less significant than the Renaissance of the age of German Enlightenment. It was “French Spinozism” that brought the study of Spinoza’s philosophy to the international level, significantly expanding their conceptual framework. (shrink)

One of the UN’s 17 sustainable development goals is to end hunger, achieve food security and improved nutrition by 2030. This goal will be missed. Global hunger is still highly prevalent. In 2021, about 821 million people experience undernourishment every day and more are at risk. Is this necessary? This article calculates the investments needed for both acute and sustainable systems to alleviate food insecurity and decrease global caloric deficits. These economic values are then contextualized by comparing funds spent by (...) individuals and governments on unnecessary or counterproductive products. The results show that divergence of even small fractions of these funds from food waste, tobacco, alcohol, or weapons within the U.S. alone could supplement the caloric needs of those in areas with high levels of food insecurity. America’s net-negative industries whose advertisements and sales could be taxed to improve America’s life expectancy could fund the yearly cost to feed anywhere from 17.1% to 1,467.9% of malnourished people directly, or contribute more than 100% of the estimated cost to sustainably end global hunger. It is concluded that reallocating funds that are detrimental to the U.S. population is a path to achieving food security and sustainable food production for the entire globe. (shrink)
