The discourse marker use of the word like is considered by many to be superfluously sprinkled into talk, a bad habit best avoided. But a comparison of the use of like in successive tellings of stories demonstrates that like can be anticipated in advance and planned into stories. In this way, like is similar to other words and phrases tellers recycle during story telling. The anticipation of like contrasted with the uses of other discourse markers such as oh, you know, (...) and well, which almost never re-occurred in similar locations across tellings. Um and uh did sometimes re-occur; these uses are contrasted with like. Although discourse markers are generally used on the fly to handle various issues that come up in coordinating talk as it unfolds, like can be used as an integral part of the story -a marked contrast to the prevalent idea that likes are speech tics.

Words like well, oh, and you know have long been observed and studied in spontaneous speech. With the proliferation of on-line dialogues, such as instant messaging between friends or back-and-forth postings at websites, there are increasing opportunities to observe them in spontaneous writing. In Experiment 1, the interpretation of discourse markers in on-line debates was compared to proposed functions of those markers identified in other settings. In Experiment 2, the use of discourse markers in spontaneous speech was compared to their (...) uses in spontaneous writing. Results support the conclusion that although they vary in frequency in spoken versus written domains, discourse markers are used similarly across domains, but with particular communicative functions that make them non-interchangeable.

Bilingualism has been identified as a potential cognitive factor linked to delayed onset of dementia as well as boosting executive functions in healthy individuals. However, more recently, this claim has been called into question following several failed replications. It remains unclear whether these contradictory findings reflect how bilingualism is defined between studies, or methodological limitations when measuring the bilingual effect. One key issue is that despite the claims that bilingualism yields general protection to cognitive processes, studies reporting putative bilingual differences (...) are often focused on domain specific experimental paradigms. This study chose a broader approach, by considering the consequences of bilingualism on a wide range of cognitive functions within individuals. We utilised 19 measures of different cognitive functions commonly associated with bilingual effects, to form a “cognitive profile” for 215 non-clinical participants. We recruited Welsh speakers, who as a group of bilinguals were highly homogeneous, as means of isolating the bilingualism criterion. We sought to determine if such analyses would independently classify bilingual/monolingual participant groups based on emergent patterns driven by collected cognitive profiles, such that population differences would emerge. Multiple predictive models were trained to independently recognise the cognitive profiles of bilinguals, older adults and higher education attainment. Despite managing to successfully classify cognitive profiles based on age and education, the model failed to differentiate between bilingual and monolingual cognitive ability at a rate greater than that of chance. Repeated modelling using alternative definitions of bilingualism, and just the older adults, yielded similar results. In all cases then, using our “bottom–up” analytical approach, there was no evidence that bilingualism as a variable indicated differential cognitive performance – as a consequence, we conclude that bilinguals are not cognitively different from their monolingual counterparts, even in older demographics. We suggest that studies that have reported a bilingual advantage could well have confounded other key variables that may be driving reported advantages. We recommend that future research refine the machine learning methods used in this study to further investigate the complex relationship between bilingualism and cognition. (shrink)

Comparing people to trees is a customary and common practice in Jewish tradition. The current article examines the roots and the development of the image of people as trees in Jewish sources, from biblical times to recent generations, as related to the prohibition against destroying fruit trees. The similarity between humans and trees in the Jewish religion and culture was firstly suggested in biblical literature as a conceptual-symbolic element. However, since the Amoraic period, this similarity was transformed to (...) a resemblance bearing mystical and Halakhic implications. Various sources in rabbinical literature describe trees as humans that may be spoken to or yelled at to produce fruit. Cutting down a tree was perceived by the rabbis of the Talmud not only as an unethical act or vandalism, but also as a hazard: the death of the tree corresponds to the death of the person who resembles it. All societies, cultures and religions have a system of values and practices that are aimed at shaping people, society and the environment according to a certain worldview.Contribution: The discussion in this article on the relationship between religion-culture and nature indicates how the Jewish religion shaped believers’ attitude to the world of flora over the generations by transforming the man-tree comparison into one with binding and even threatening practical religious meaning.

"The Natural System" is the name given to the underlying arrangement present in the diversity of life. Unlike a classification, which is made up of classes and members, a system or arrangement is an integrated whole made up of connected parts. In the pre-evolutionary period a variety of forms were proposed for the Natural System, including maps, circles, stars, and abstract multidimensional objects. The trees sketched by Darwin in the 1830s should probably be considered the first genuine evolutionary diagrams of (...) the Natural System—the first genuine evolutionary trees. Darwin refined his image of the Natural System in the well-known evolutionary tree published in the Origin of Species, where he also carefully distinguished between arrangements and classifications. Following the publication of the Origin, there was a great burst of evolutionary tree building, but interest in trees declined substantially after 1900, only to be revived in recent years with the development of cladistic analysis. ¶ While evolutionary trees are modern diagrams of the Natural System, they are at the same time instances of another broad class of diagrams that may be called "trees of history": branching diagrams of genealogical descent and change. During the same years that Darwin was sketching his first evolutionary trees, the earliest examples of two other trees of history also appeared: the first trees of language evolution and of manuscript genealogy. Though these were apparently independent of evolutionary trees in their origin, the similarities among all these trees of history, and among the historical processes that underlie them, were soon recognized. Darwin compared biological evolution and language evolution several times in the Origin of Species, and both Ernst Haeckel and the linguist August Schleicher made similar comparisons. Both linguists and stemmaticists (students of manuscript descent) understood the principle of apomorphy—the principle that only shared innovations provide evidence of common ancestry—more clearly than did systematists, and if there had been more cross-fertilization among these fields the cladistic revolution in systematics might well have taken place in the nineteenth century. ¶ Although historical linguists and stemmaticists have in some respects had sounder theory than have systematists, at least until recently, they have also had the practical problem of very large amounts of data, a problem not often faced by systematists until the advent of molecular sequencing. The opportunity now exists for systematists to contribute to the theory and practice of linguistics and stemmatics, their sister disciplines in historical reconstruction, through application of our commonly used computer programs for tree estimation. Preliminary results from the application of numerical cladistic analysis to a large stemmatic data set have been very encouraging, and have already generated much discussion in the stemmatics community.

We study descriptive set theory in the space ω1 ω 1 by letting trees with no uncountable branches play a similar role as countable ordinals in traditional descriptive set theory. By using such trees, we get, for example, a covering property for the class of Π 1 1 -sets of ω1 ω 1 . We call a family U of trees universal for a class V of trees if $\mathscr{U} \subseteq \mathscr{V}$ and every tree in V can be order-preservingly (...) mapped into a tree in U. It is well known that the class of countable trees with no infinite branches has a universal family of size ℵ 1 . We shall study the smallest cardinality of a universal family for the class of trees of cardinality ≤ℵ 1 with no uncountable branches. We prove that this cardinality can be 1 (under ¬CH) and any regular cardinal κ which satisfies ℵ 2 ≤ κ ≤ 2 ℵ 1 (under CH). This bears immediately on the covering property of the Π 1 1 -subsets of the space ω1 ω 1 . We also study the possible cardinalities of definable subsets of ω1 ω 1 . We show that the statement that every definable subset of ω1 ω 1 has cardinality $ or cardinality 2 ω1 is equiconsistent with ZFC (if n ≥ 3) and with ZFC plus an inaccessible (if n = 2). Finally, we define an analogue of the notion of a Borel set for the space ω1 ω 1 and prove a Souslin-Kleene type theorem for this notion. (shrink)

The typical rules for truth-trees for first-order logic without functions can fail to generate finite branches for formulas that have finite models–the rule set fails to have the finite tree property. In 1984 Boolos showed that a new rule set proposed by Burgess does have this property. In this paper we address a similar problem with the typical rule set for first-order logic with identity and functions, proposing a new rule set that does have the finite tree property.

The Tree of Nature represents an IT-based approach to understanding Nature in the light of present-day scientific knowledge. The universe, in this view, consists of discrete entities; these are not material particles, however, but information processing events that produce observable changes in the world. The surprising result of this analysis is that the workings of Nature are based on a decision tree consisting of two dozen parameters. The tree is similar to the evolutionary phylogenetic system of the (...) various forms of life, but it is far more fundamental; constituting, as it does, the very base of everything that exists. The overall conclusion is that the universe is steadily producing new information. Metaphorically speaking, it constitutes a self-unfolding story in which events do not pass away into non-existence but instead remain forever as an indelible part of the whole. This also holds true for integrated sets of events, such as the lifetime experiences of an individual. The Tree of Nature leads to the following testable prediction: A successful quantum-gravity theory will involve the notion of a strong complementarity between gravity and the strong nuclear force.

We study descriptive set theory in the space $^{\omega_1}\omega_1$ by letting trees with no uncountable branches play a similar role as countable ordinals in traditional descriptive set theory. By using such trees, we get, for example, a covering property for the class of $\Pi^1_1$-sets of $^{\omega_1}\omega_1$. We call a family $\mathscr{U}$ of trees universal for a class $\mathscr{V}$ of trees if $\mathscr{U} \subseteq \mathscr{V}$ and every tree in $\mathscr{V}$ can be order-preservingly mapped into a tree in $\mathscr{U}$. It (...) is well known that the class of countable trees with no infinite branches has a universal family of size $\aleph_1$. We shall study the smallest cardinality of a universal family for the class of trees of cardinality $\leq\aleph_1$ with no uncountable branches. We prove that this cardinality can be 1 (under $\neg$CH) and any regular cardinal $\kappa$ which satisfies $\aleph_2 \leq \kappa \leq 2^{\aleph_1}$ (under CH). This bears immediately on the covering property of the $\Pi^1_1$-subsets of the space $^{\omega_1}\omega_1$. We also study the possible cardinalities of definable subsets of $^{\omega_1}\omega_1$. We show that the statement that every definable subset of $^{\omega_1}\omega_1$ has cardinality $<\omega_n$ or cardinality $2^{\omega_1}$ is equiconsistent with ZFC (if $n \geq 3$) and with ZFC plus an inaccessible (if $n = 2$). Finally, we define an analogue of the notion of a Borel set for the space $^{\omega_1}\omega_1$ and prove a Souslin-Kleene type theorem for this notion. (shrink)

In several works on modality, G. H. von Wright presents tree structures to explain possible worlds. Worlds that might have developed from an earlier world are possible relative to it. Actually possible worlds are possible relative to the world as it actually was at some point. Many logically consistent worlds are not actually possible. Transitions from node to node in a tree structure are probabilistic. Probabilities are often more useful than similarities between worlds in treating counterfactual conditionals.

Tylman has recently pointed out some striking conceptual and methodological analogies between philosophy and computer science. In this paper, I focus on one of Tylman’s most convincing cases, viz. the similarity between Plato’s theory of Ideas and the object-oriented programming paradigm, and analyze it in some more detail. In particular, I argue that the platonic doctrine of the Porphyrian tree corresponds to the fact that most object-oriented programming languages do not support multiple inheritance. This analysis further reinforces Tylman’s (...) point regarding the conceptual continuity between classical metaphysical theorizing and contemporary computer science. (shrink)

Let U and B be two countable relational models of the same first order language. If the models are nonisomorphic, there is a unique countable ordinal α with the property that $\mathfrak{U} \equiv^\alpha_{\infty\omega} \mathfrak{B} \text{but not} \mathfrak{U} \equiv^{\alpha + 1}_{\infty\omega} \mathfrak{B},$ i.e. U and B are L ∞ω -equivalent up to quantifier-rank α but not up to α + 1. In this paper we consider models U and B of cardinality ω 1 and construct trees which have a similar relation (...) to U and B as α above. For this purpose we introduce a new ordering T ≪ T' of trees, which may have some independent interest of its own. It turns out that the above ordinal α has two qualities which coincide in countable models but will differ in uncountable models. Respectively, two kinds of trees emerge from α. We call them Scott trees and Karp trees, respectively. The definition and existence of these trees is based on an examination of the Ehrenfeucht game of length ω 1 between U and B. We construct two models of power ω 1 with 2 ω 1 mutually noncomparable Scott trees. (shrink)

It is often said that there is just one “objective” tree of life: a single accurate branching hierarchy of species reflecting order of descent. For any two species there is a single correct answer as to whether one is a “daughter” of the other, whether the two are “sister species” by virtue of their descent from a common parental species, whether they belong to a family line that excludes any given third species, and so on. This position is not (...) right. We may whittle a tree of life, paring troublesome branches, in order to portray an ordering that admits of no legitimate dissent. But the history of life can sustain many legitimate arrangements of the same branches of species. The same can be said about other taxonomically relevant groups besides species, such as “Least Inclusive Taxonomic Units” (LITUs), so the basic claim survives even if we abandon traditional species. Similarly, the claim survives even if we distinguish between synchronic and diachronic groups, even if we consider polytomies, even if we distinguish between models and the world modeled, and even if we recognize an objective world. Nor is the claim merely an epistemic one. (shrink)

This essay seeks to examine the history of the intellectual comradeship between J.L. Talmon and the philosopher, political thinker, and historian of ideas, Isaiah Berlin (1909–1997). The scholarly dialog between the two began in 1947, continued until Talmon's death in 1980, and is well documented in their private correspondence. I argue that there were two levels to this dialog: First, both Berlin and Talmon took part in the Totalitarianism discourse, which was colored by Popperian terminology, and thus I claim that (...) their ideas should be examined as part of the Cold-War political discourse. The second level stemmed from their similar East-European origin, their mutual Jewish identity, and their attitude towards the Zionist movement. At times the two levels of discourse conjoined commensurably, but in other cases the juxtaposition of the two created conceptual tensions. Examining Berlin and Talmon's thought from this dual perspective, I argue, can shed new light on the inner conflicts and conceptual tensions that each of them had to face. In particular, I claim that both thinkers tried to integrate their Anglophile liberal heritage with their support of National movements in general, and the Jewish National movement in particular. Nevertheless, the different approaches of Talmon and Berlin present two concepts of liberal Nationalism: While Talmon assumed that Zionism solved the Jewish individual's dilemmas by making Jews members of a commune attached to soil; Berlin sought to preserve the individual in an inviolable sphere and thus was more ambivalent in his attitude towards the state of Israel. In conclusion, I offer to see Talmon as a classic Zionist liberal and Berlin as a supporter of what I call “Diaspora Zionism”, an approach, which would later provide the grounds for Berlin's celebrated pluralism.

Andrey Bely's autobiographical novel Kotik Letaev and Terrence Malick's film The Tree of Life do not share a common subtext. Nevertheless, they have strikingly similar themes. They each deal with an adult's confrontation of his past through memory, a memory that extends back before birth. Coming to terms with the past prepares the adult protagonist of each work for his destiny. The essay discusses Malick's use of William Blake's mysticism and Bely's dependence on the religious-philosophical ideas of Rudolf Steiner. (...) Memory plays an important role in both works as it touches on the recapitulation of cosmic origins in the development of the individual human being. What the quester discovers through memory enables him to find the way back to Eternity from which he has descended. Both artists invoke the World Tree uniting heaven and earth and its association with the Cross of Christ. In both the novel and the film the world is seen first through a child's eyes, then through growing understanding of the adult. Malick illustrates with cinematography what Bely describes in words. Malick uses music in a way that fleshes out what Bely attempted to create through using musical tropes in language. (shrink)

The computer is more then a mere machine. Starting with questions of Intelligence, Artificial Intelligence and Neural Network we proceeded to Artificial Life. This new science raises fear and doubts which are similar to other historical intolerances and fears, mainly concerned with the progression of science and technology that littered our history. Yet Artificial Life is different as it addresses directly the fate of our race. Some consider it as its salvation, while others see it as its annihilator. The promises (...) could be great but so are the risks. Following a historical route of promises and fears we would like to analyze the place of Artificial Life in our life. (shrink)

The perception of semantic similarity derives from distinct processes of comparison and integration. A dual process model of conceptual combination claims that attributive combination (e.g., umbrella tree) entails comparison, while relational combination (e.g., pancake spatula) requires integration. The present research uses similarity as a test of this dual process model. Participants (N = 168) were presented attributive and relational conceptual combinations. Half of the participants interpreted the combinations before rating the similarity of their constituent concepts, while (...) the other half provided similarity ratings without interpreting the concepts together. The experiment revealed that attributive combination decreased the perceived similarity of the constituent concepts, whereas relational combination increased the similarity of the constituents. This result indicates that attributive and relational combination occur via distinct processes. Results of a post‐test (N = 60) suggested that these effects were specific to the particular concepts compared or integrated, and do not generalize to other concepts not compared or integrated. The present research thus supported a dual process model of conceptual combination by demonstrating differential effects of comparison and integration on the perception of semantic similarity.

This study critiques the idea of a “Western science -- indigenous knowledge” dichotomy in agricultural knowledge by examining the hybrid nature of knowledge use and incorporation by villagers in Madhya Pradesh, India. By analyzing knowledge systems as multi-leveled structures consisting of concrete practices linked to more abstract, explanatory concepts, this paper illustrates how information from multiple sources is integrated into local bodies of knowledge about tree management. Practices such as urea fertilization from formal global science might be explained by (...) concepts such as that of a hot/cold duality from informal folk science. Similarly, other pieces of knowledge stemming from diverse knowledge systems are shown to become mixed and matched on practical and conceptual levels. Additionally, several knowledge elements used locally appear to be held in common by many knowledge systems around the world, rendering the determination of their origins in one system or another nearly impossible. These observations lead to the conclusion that local knowledge systems of tree management are better characterized as “open” systems rather than distinct, “closed” systems. Furthermore, the constant exchange of material between formal and informal, local and global systems renders untenable any strict dichotomy of knowledge systems. (shrink)

Searching is one of the most fundamental operations in many complex systems. However, the complexity of the search process would increase dramatically in high-dimensional space. K-dimensional tree, as a classical data structure, has been widely used in high-dimensional vital data search. However, at present, common methods proposed for KD tree construction are either unstable or time-consuming. This paper proposed a new algorithm to construct a balanced KD tree based on presorted results. Compared with previous similar method, the (...) new algorithm could reduce the complexity of the construction process from O level to O level, where K is the number of dimensions and N is the number of data. In addition, with the help of presorted results, the performance of the new method is no longer subject to the initial conditions, which expands the application scope of KD tree. (shrink)

A recent study(1) of sequence data from many different proteins has suggested that contemporary prokaryotes and eukaryotes may have shared a common ancestor as recently as 2 billion years ago (the molecular clock). Strong evidence from the geological record, however, indicates that oxygen‐producing microorganisms, perhaps similar to modern cyanobacteria, existed 3.5 billion years ago. The fossil evidence, therefore, suggests that any common ancestor of prokaryotes and eukaryotes must have existed at least 1.5 billion years earlier than suggested by the molecular (...) clock evidence. The discrepancy between molecular and geological evidence for the age of modern cells is considered here, as are aspects of gene descent in the tree of life that might help to account for it.

Observational and experimental discoveries of new factual entities such as objects, systems, or processes, are major contributors to some advances in the life sciences. Yet, whereas discovery of theories was extensively deliberated by philosophers of science, very little philosophical attention was paid to the discovery of factual entities. This paper examines historical and philosophical aspects of the experimental discovery by Carl Woese of archaea, prokaryotes that comprise one of the three principal domains of the phylogenetic tree. Borrowing Kuhn’s terminology, (...) this discovery of a major biological entity was made during a ‘normal science’ project of building molecular taxonomy for prokaryotes. Unexpectedly, however, an observed anomaly instigated the discovery of archaea. Substantiation of the existence of the new archaeal entity and consequent reconstruction of the phylogenetic tree prompted replacement of a long-held model of a prokarya and eukarya bipartite tree of life by a new model of a tripartite tree comprising of bacteria, archaea, and eukarya. This paper explores the history and philosophical implications of the progression of Woese’s project from normal science to anomaly-instigated model-changing discovery. It is also shown that the consequential discoveries of RNA splicing and of ribozymes were similarly prompted by unexpected irregularities during normal science activities. It is thus submitted that some discoveries of factual biological entities are triggered by unforeseen observational or experimental anomalies. (shrink)

The present article, which is a revised version of part of [Hu1], deals with various relations between models which might serve as exact formulations for the vague concept "similar" or "almost isomorphic". One natural class of such formulations is equivalence in a given logic. Another way to express similarity is by potential isomorphism, i.e., isomorphism in some extension of the set-theoretic universe. The class of extensions may be restricted to give different notions of potential isomorphism. A third method is (...) to study the winning strategies for an Ehrenfeucht-Fraisse-game played between the two models, and the properties of the resulting equivalence and nonequivalence trees. The basic question studied here is whether one such notion of similarity implies another. Some implications and counterexamples listed in this part are previously known or trivial, but all are mentioned for completeness' sake. Only models of cardinality ℵ 1 are considered. Some results are therefore connected with the Continuum Hypothesis. (shrink)

This paper will compare the concept of nature as it appears in the philosophies of the American pragmatist John Dewey and the Chinese text known as the Zhuangzi, with an aim towards mapping out a heuristic program which might be used to correct various interpretive difficulties in reading each figure.

Such a view of nature turns on the (...) notion of continuity, particularly that between an experiencing organism [Dewey’s “live creature”] and the conditioning environment [Zhuangzi’s “crooked tree”]. Where Dewey’s and Zhuangzi’s ideas about nature converge, one finds similarities in prescriptions made for human action, and in the few places where they differ, one finds mutually complementary insights.

We propose in this article an indexing and retrieval approach applied on outline shapes. Models of objects are stored in a database using the textual descriptors of their silhouettes. We extract from the textual description a set of efficient similarity measures to index the silhouettes. The extracted features are the geometric quasi-invariants that vary slightly with the small change in the viewpoint. We use a textual description and quasi-invariant features to minimize the storage space and to achieve an efficient (...) indexing process. We also use the quad-tree structure to improve processing time during indexing. Using both geometric features and quad-tree decomposition facilitates recognition and retrieval processes. Our approach is applied on the outline shapes of three-dimensional objects. Experiments conducted on two well-known databases show the efficiency of our method in real-world applications, especially for image indexing and retrieval. (shrink)

The two great modern naturalists, Linnaeus and Darwin, expressed their intuition about how best to visualize patterns of affinities, that is, morphological similarities and divergences between taxa. Linnaeus suggested that “all plants show affinities on all sides, like a territory on a geographical map,” while Darwin thought that it was virtually impossible to understand the affinities between living and extinct species without a genealogical tree. Genealogical trees follow the diachronic, evolving logic of a timeline, whereas maps depict a synchronous (...) pattern of extant taxa. Although the two seem unrelated, various naturalists made attempts to combine them. Surprisingly, these resulted in three-dimensional images that, in order to be observed, had to be projected on paper. The naturalists Max Fürbringer and Richard Bowdler Sharpe were aware of this fact, but even Darwin himself twice combined the basic intuitions underlying the two modes of representation to produce three-dimensional images. This article is a brief history of the efforts to merge genealogical trees and map-like cross sections of affinities into one three-dimensional image. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 20 (2000) 151-165 [Access article in PDF] Santayana and Buddhism: The Choice between the Cross and the Bo Tree Paul Grimley KuntzEmory UniversitySantayana honors Gotama Buddha as a profound religious genius as well as an original philosopher. Gotama's way is genuine spiritual wisdom, and constantly compared with Christian mysticism as a way of enlightenment. It is therefore understandable that a Spaniard, who learned his catechism in (...) Ávila, and who was educated in the New England of Emerson and other Transcendentalists who honored Oriental wisdom, should have so much to say about the Buddha and Buddhism.The effort of this paper is to gather many of the isolated passages to give a coherent picture of Santayana and Buddhism. One difficulty to be overcome is that the philosopher rarely quotes his sources (the exception is a single quotation from Dasgupta). Although Santayana has numerous opinions, he does not reveal on which translations he has relied. Nor does he contrast different traditions of Buddhists. To overcome the vagueness of scholarship, I have used the volumes found in Widener Library: the sorts of books known to Santayana's dissertation director, Josiah Royce, and those of a sympathetic sort that had led Santayana as early as the writing of his dissertation on Rudolf Hermann Lotze to reject the latter's defiantly Christian and Western contempt for oriental "superstition." The sympathy can be expressed as similar to that of Schopenhauer in reading the Upanishads or Wilhelm von Humboldt in studying the Bhagavadgita. Santayana's study makes him aware of his Catholicism but he is unlike the Jesuit Dahlmann who attacks Buddhism as Nihilism. Santayana is more like his contemporaries who worked in psychology and philosophy of religion. Although Friedrich Heiler's work 1 and writings of James Bissett Pratt 2 were a bit too late to have influenced Santayana, comparison serves to illuminate and strengthen Santayana's conclusions. Perhaps Heiler is even more appropriate because Buddhistic insights remind him of those of St. Theresa. Santayana would support Pratt's view that Nirvana is not the annihilation of all desire but the extinguishing of evil passions. What Santayana finds congenial in Christian Neo-Platonism and in Spinoza, as well as in Buddhism, is the achievement of freedom of the spirit. 3 It has become a commonplace of world history that the two greatest founders of religion whose ways of salvation triumphed in Europe and in Asia respectively are the Christ and the Buddha. Philosophers of religion like Heiler accept both as saviors with a universal message, one, Jesus "the master of prayer" ("der Meister des Gebets"), the [End Page 151] other, Gotama "the master of contemplation" ("der Meister der Versenking"). Santayana is not concerned with the fact of the success of their missions, for there are indeed other triumphs such as Mohammed's Islam, and if it be classified as a religion, Marx's Communism. Santayana is hardly offering his services as a philosophic mediator, as Whitehead tries to do in Religion in the Making, to bring the two communities of faith to a closer approximation of a truly universal religion. 4Santayana reveals great personal depth as he ponders the contrast between the Gospel and the Fourfold Noble Truth. What is the appeal of Christ on the Cross dying "to save us?" What is the appeal of "the serene Buddha, lifting the finger of meditation and profound counsel?" 5 These questions are asked in a meditation in Soliloquies in England in the sympathetic way of those American philosophers who like Pratt have the option of remaining Christian or converting to Buddhism. William James might well have patted Santayana on the back for struggling with the alternatives, for wrestling with a live option. Probably because of Buddha's message of truth, Santayana has shifted from religion as poetry, which James considered "rotten," to how "a general truth about existence and experience" is symbolized poetically, which James would consider healthy.In answering the question "What does the cross signify?" Santayana strips away the "various analogies, legal, sentimental, or chivalrous," and he... (shrink)

In this paper we first give a variant of a theorem of Jockusch–Lewis– Remmel on existence of a computable, degree-preserving homeomorphism between a bounded strong ${\Pi^0_2}$ class and a bounded ${\Pi^0_1}$ class in 2 ω . Namely, we show that for mathematically common and interesting topological spaces, such as computably presented ${\mathbb{R}^n}$ , we can obtain a similar result where the homeomorphism is in fact the identity mapping. Second, we apply this finding to give a new, priority-free proof of existence (...) of a tree of shadow points computable in 0′. (shrink)

Failure to take note of distinctive attributes in the distal stimulus leads to an inadequate proximal encoding. Representation of similarities in Chorus suffers in this regard. Distinctive qualities may require additional complex representation (e.g., reference to linguistic terms) in order to facilitate discrimination. Additional semantic information, which configures proximal attributes, permits accurate identification of true veridical stimuli.

The course of biological evolution is regarded by many authors as an ascending path toward higher levels of variety, complexity and integration. There are similar but partly conflicting accounts of the nature and causes of this ascending course. With the aim of reaching a unified conception I start by summarily reviewing three notable examples. These are, in their latest presentations, those of Hoffmeyer and Stjernfelt 2015, Szathmáry 2015, and Lane 2015a. Comparison of their commonalities and divergences, combined with further reflections, (...) leads to the following views: 1) cooperation between preexistent traits and processes is the primary determinant in the emergence of evolutionary novelty; 2) cooperation is a triadic relation similar to semiosis ; 3) regulation, the key element of both metabolism and replication, results from the cooperation of energetic and semiotic causation; 4) conceptual generalization and concrete generalization are fruits of cooperation. Conceptual generalizations spring from the cooperation of ideas. I believe these realizations supply essential elements for a unified view of the ascent of biological evolution towards higher levels of organization. Some of these conceptions are also applicable to similar ascending trajectories through the stages of cultural and technological evolution. (shrink)

For [Formula: see text], the coarse similarity class of [Formula: see text], denoted by [Formula: see text], is the set of all [Formula: see text] such that the symmetric difference of [Formula: see text] and [Formula: see text] has asymptotic density [Formula: see text]. There is a natural metric [Formula: see text] on the space [Formula: see text] of coarse similarity classes defined by letting [Formula: see text] be the upper density of the symmetric difference of [Formula: see (...) text] and [Formula: see text]. We study the metric space of coarse similarity classes under this metric, and show in particular that between any two distinct points in this space there are continuum many geodesic paths. We also study subspaces of the form [Formula: see text] where [Formula: see text] is closed under Turing equivalence, and show that there is a tight connection between topological properties of such a space and computability-theoretic properties of [Formula: see text]. We then define a distance between Turing degrees based on Hausdorff distance in the metric space [Formula: see text]. We adapt a proof of Monin to show that the Hausdorff distances between Turing degrees that occur are exactly [Formula: see text], [Formula: see text], and [Formula: see text], and study which of these values occur most frequently in the senses of Lebesgue measure and Baire category. We define a degree [Formula: see text] to be attractive if the class of all degrees at distance [Formula: see text] from [Formula: see text] has measure [Formula: see text], and dispersive otherwise. In particular, we study the distribution of attractive and dispersive degrees. We also study some properties of the metric space of Turing degrees under this Hausdorff distance, in particular the question of which countable metric spaces are isometrically embeddable in it, giving a graph-theoretic sufficient condition for embeddability. Motivated by a couple of issues arising in the above work, we also study the computability-theoretic and reverse-mathematical aspects of a Ramsey-theoretic theorem due to Mycielski, which in particular implies that there is a perfect set whose elements are mutually [Formula: see text]-random, as well as a perfect set whose elements are mutually [Formula: see text]-generic. Finally, we study the completeness of [Formula: see text] from the perspectives of computability theory and reverse mathematics. (shrink)

Being building block of data sciences, link prediction plays a vital role in revealing the hidden mechanisms that lead the networking dynamics. Since many techniques depending in vertex similarity and edge features were put forward to rule out many well-known link prediction challenges, many problems are still there just because of unique formulation characteristics of sparse networks. In this study, we applied some graph transformations and several inequalities to determine the greatest value of first and second Zagreb invariant, S (...) K and S K 1 invariants, for acyclic connected structures of given order, diameter, and pendant vertices. Also, we determined the corresponding extremal acyclic connected structures for these topological indices and provide an ordering giving a sequence of acyclic connected structures having these indices from greatest in decreasing order.

This dissertation will compare the concept of nature as it appears in the philosophies of the American pragmatist John Dewey and the Chinese daoist Zhuangzi and will defend two central claims. The first of these is that Dewey and Zhuangzi share a view of nature that is non-reductive, philosophically liberal, and more comprehensive than the accounts recurrent in much of the Western tradition. This alternate conception of nature is non-reductive in the way that it avoids the physically mechanistic outlook underwriting (...) much of contemporary Anglo-American thought. It is philosophically liberal in that it accepts a more generous and progressive position than predominant Western orthodoxies. And, it is more comprehensive in scope insofar as it draws as much from the social sciences as it does from the natural sciences. The second claim defended will be that the synoptic vision gained from such a comparison offers a new heuristic program for research into the philosophical position known as naturalism, a program that can, at once, avoid the scientistic tendencies of the current, mainstream treatment of nature and reconnect with earlier, more inclusive models. Where Dewey's and Zhuangzi's ideas converge, one finds similarities in the prescriptions each made for human action, and where they differ, one finds mutually complementary insights. Finally, this heuristic will be used to refute various interpretations of Dewey and Zhuangzi that tend to understate or ignore the importance of nature within their schemes. (shrink)

In organisms, ribonucleic acid plays an essential role. Its function is being discovered more and more. Due to the conserved nature of RNA sequences, its function mainly depends on the RNA secondary structure. The discovery of an approximate relationship between two RNA secondary structures helps to understand their functional relationship better. It is an important and urgent task to explore structural similarities from the graphical representation of RNA secondary structures. In this paper, a novel graphical analysis method based on the (...) triple vector curve representation of RNA secondary structures is proposed. A combinational method involving a discrete wavelet transform and fractal dimension with sliding window is introduced to analyze and compare the graphs derived from feature extraction; after that, the distance matrix is generated. Then, the distance matrix is analyzed by clustering and visualized as a clustering tree. RNA virus and noncoding RNA datasets are applied to perform experiments and analyze the clustering tree. The results show that the proposed method yields more accurate results in the comparison of RNA secondary structures. (shrink)

We explored the differential impact of auditory information and written contextual information on the recognition of verbal irony in spontaneous speech. Based on relevance theory, we predicted that speakers would provide acoustic disambiguation cues when speaking in situations that lack other sources of information, such as a visual channel. We further predicted that listeners would use this information, in addition to context, when interpreting the utterances. People were presented with spontaneously produced ironic and nonironic utterances from radio talk shows in (...) written or auditory form, with or without written contextual information. When the utterances were read without written contextual information, all utterances were rated as equally ironic. But when they were heard as opposed to read, or when they were presented in irony-biasing contexts, originally ironic utterances were rated as more sarcastic than originally nonironic utterances. This evidence suggests both acoustic and contextual information are used when inferring ironic intent in spontaneous speech, and validates previous manipulations of intonation in studies of irony understanding.

To generate empathy in the care of vulnerable older persons requires care providers to reflect critically on their care practices. Ethics education and training must provide them with tools to accomplish such critical reflection. It must also create a pedagogical context in which good care can be taught and cultivated. The care-ethics lab ‘sTimul’ originated in 2008 in Flanders with the stimulation of ethical reflection in care providers and care providers in training as its main goal. Also in 2008, sTimul (...) commenced the organization of empathy sessions as an attempt to achieve this goal by simulation. The empathy session is a practical and fairly straightforward way of working to provoke care providers and care providers in training to engage in ethical reflection. Characteristic of the empathy session in the care-ethics lab is the emphasis on experience as a basis for ethical reflection. (shrink)

Observing others in conversation is a common format for comprehending language, yet little work has been done to understand dialog comprehension. We tested whether overhearers use addressee backchannels as predictive cues for how to integrate information across speaker turns during comprehension of spontaneously produced collaborative narration. In Experiment 1, words that followed specific backchannels were recognized more slowly than words that followed either generic backchannels or pauses. In Experiment 2, we found that when the turn after the backchannel was a (...) continuation of the narrative, specific backchannels prompted the fastest verification of prior information. When the turn after was an elaboration, they prompted the slowest, indicating that overhearers took specific backchannels as cues to integrate preceding talk with subsequent talk. These findings demonstrate that overhearers capitalize on the predictive relationship between backchannels and the development of speakers’ talk, coordinating information across conversational roles.
