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.

Stem cells did not become a proper research object until the 1960 s. Yet the term and the basic mind-set—namely the conception of single undifferentiated cells, be they embryonic or adult, as the basic units responsible for a directed process of development, differentiation and increasing specialisation—were already in place at the end of the nineteenth century and then transmitted on a non-linear path in the form of tropes and diagrams. Ernst Haeckel and August Weismann played a special role in this (...) story. The first coined the term Stammzelle (stem cell), the second was the author of the first cellular stem-tree diagram. Even today, I shall argue, the understanding of stem cells, especially the popular perception, is to a large extent a Haeckelian–Weismannian one. After having demonstrated this, by analysing the terminology, in this essay I will focus on the use of cytogenetic tree diagrams between 1892 and 1925 and on the tacit understanding of stem cells that they transmit.

There is an exponential speed-up in the number of lines of the quantified propositional sequent calculus over Substitution Frege Systems, if one considers proofs as trees. Whether this is true also for the number of symbols, is still an open problem.

We investigate some versions of amoeba for tree-forcings in the generalized Cantor and Baire spaces. This answers [10, Question 3.20] and generalizes a line of research that in the standard case has been studied in [11], [13], and [7]. Moreover, we also answer questions posed in [3] by Friedman, Khomskii, and Kulikov, about the relationships between regularity properties at uncountable cardinals. We show ${\bf{\Sigma }}_1^1$-counterexamples to some regularity properties related to trees without club splitting. In particular we prove a (...) strong relationship between the Ramsey and the Baire properties, in slight contrast with the standard case. (shrink)

The "tree of life" iconography, representing the history of life, dates from at least the latter half of the 18th century, but evolution as the mechanism providing this bifurcating history of life did not appear until the early 19th century. There was also a shift from the straight line, scala naturae view of change in nature to a more bifurcating or tree-like view. Throughout the 19th century authors presented tree-like diagrams, some regarding the Deity as the mechanism (...) of change while others argued for evolution. Straight-line or anagenetic evolution and bifurcating or cladogenetic evolution are known in biology today, but are often misrepresented in popular culture, especially with anagenesis being confounded with scala naturae. Although well known in the mid 19th century, the geologist Edward Hitchcock has been forgotten as an early, if not the first author to publish a paleontologically based "tree of life" beginning in 1840 in the first edition of his popular general geology text Elementary Geology. At least 31 editions were published and those between 1840 and 1859 had this "paleontological chart" showing two trees, one for fossil and living plants and another for animals set within a context of geological time. Although the chart did not vary in later editions, the text explaining the chart did change to reflect newer ideas in paleontology and geology. Whereas Lamarck, Chambers, Bronn, Darwin, and Haeckel saw some form of transmutation as the mechanism that created their "trees of life," Hitchcock, like his contemporaries Agassiz and Miller, who also produced "trees of life," saw a deity as the agent of change. Through each edition of his book Hitchcock denounced the newer transmutationist hypotheses of Lamarck, then Chambers, and finally Darwin in an 1860 edition that no longer presented his tree-like "paleontological chart.".

The paper aims at critical reconsideration of a motif popular in Indian literary, ritual, and pictorial traditions – a tree goddess (yakṣī, vṛkṣakā) or a woman embracing a tree (śālabhañjīkā, dohada), which points to a close and intimate bond between women and trees. At the outset, I present the most important phases of the evolution of this popular motif from the ancient times to present days. Then two essential characteristics of nature recognized in Indian visual arts, literature, religions (...) and philosophy will be distinguished: (1) a dynamic, creative, self-sufficient and inexhaustible power, and (2) a passive, merely reproductive or vegetative, and dependent field of potentiality. The paper is to demonstrate the interdependence of the popular concepts of nature identified with femininity, and their iconic representations circulating for centuries in Indian culture, with a specific line of argument repeatedly used in social practices and public debates. While doing so, I consider the semiotic function of a cultural topos which proves to be an effective instrument for construing and supporting the gender roles and gender identities. As a modern example illustrating vitality and persuasive power of the motif of yakṣī and śālabhañjīkā, I refer to the Chipko Movement, a group of rural women based in the Garhwal Himalayas (state Uttarakhand), who fought against the mass cut of trees in the 1970s. They were involved in the wide-spread environmental campaign which significantly affected the ecological policy of the local and state authorities. Thus, a traditional motif of the visual arts has been revived and re-elaborated by the activists of this ecofeminist movement through converting the symbolic potential of yakṣī/śālabhañjīkā into social and political power.

We generalise the properties $\mathsf {OP}$, $\mathsf {IP}$, k- $\mathsf {TP}$, $\mathsf {TP}_{1}$, k- $\mathsf {TP}_{2}$, $\mathsf {SOP}_{1}$, $\mathsf {SOP}_{2}$, and $\mathsf {SOP}_{3}$ to positive logic, and prove various implications and equivalences between them. We also provide a characterisation of stability in positive logic in analogy with the one in full first-order logic, both on the level of formulas and on the level of theories. For simple theories there are the classically equivalent definitions of not having $\mathsf {TP}$ and dividing (...) having local character, which we prove to be equivalent in positive logic as well. Finally, we show that a thick theory T has $\mathsf {OP}$ iff it has $\mathsf {IP}$ or $\mathsf {SOP}_{1}$ and that T has $\mathsf {TP}$ iff it has $\mathsf {SOP}_{1}$ or $\mathsf {TP}_{2}$, analogous to the well-known results in full first-order logic where $\mathsf {SOP}_{1}$ is replaced by $\mathsf {SOP}$ in the former and by $\mathsf {TP}_{1}$ in the latter. Our proofs of these final two theorems are new and make use of Kim-independence. (shrink)

Plant succession is a phenomenon ascribed to vegetation dynamics at the scale of the plant community. The study of plant succession implies the analysis of the species involved and their relationships. Depending on the research done, the characteristics of trees have been studied according to either static, dimensional or partial approaches. We have revised the principal theories of succession, the methods of describing structure and development of tree and relationship established between tree species' attributes and their successional status. (...) During studies of succession, we propose that the profile of plant species be completed by including the organizational attributes of their structure as well as their development dynamics. We suggest an approach to the architecture that gives a general overview of the mode of development, revealing, among other things, that a limited number of architectural models may be found in nature. We hypothesize that community dynamics, in succession, may to a certain degree arise from the dynamic nature of plant development. This line of reasoning is in accordance with the current school of thought on process structuralism. (shrink)

We show that under the proper forcing axiom the class of all Aronszajn lines behave like [Formula: see text]-scattered orders under the embeddability relation. In particular, we are able to show that the class of better-quasi-order labeled fragmented Aronszajn lines is itself a better-quasi-order. Moreover, we show that every better-quasi-order labeled Aronszajn line can be expressed as a finite sum of labeled types which are algebraically indecomposable. By encoding lines with finite labeled trees, we are also able to deduce a (...) decomposition result, that for every Aronszajn line [Formula: see text] there is an integer [Formula: see text] such that for any finite coloring of [Formula: see text] there is subset [Formula: see text] of [Formula: see text] isomorphic to [Formula: see text] which uses no more than [Formula: see text] colors.

In this paper we continue the line of work initiated in “Building iteration trees”. It is shown that the existence of a certain kind of iteration tree of height ω is equivalent to the existence of a cardinal δ that is Woodin with respect to functions in the next admissible.

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)

We introduce values for rooted-tree and sink-tree digraph games axiomatically and provide their explicit formula representation. These values may be considered as natural extensions of the lower equivalent and upper equivalent solutions for line-graph games studied in van den Brink et al. (Econ Theory 33:349–349, 2007). We study the distribution of Harsanyi dividends. We show that the problem of sharing a river with a delta or with multiple sources among different agents located at different levels along the riverbed (...) can be embedded into the framework of a rooted-tree or sink-tree digraph game correspondingly.

In the automata-theoretic approach to verification, we translate specifications to automata. Complexity considerations motivate the distinction between different types of automata. Already in the 60s, it was known that deterministic Büchi word automata are less expressive than nondeterministic Büchi word automata. The proof is easy and can be stated in a few lines. In the late 60s, Rabin proved that Büchi tree automata are less expressive than Rabin tree automata. This proof is much harder. In this work we (...) relate the expressiveness gap between deterministic and nondeterministic Büchi word automata and the expressiveness gap between Büchi and Rabin tree automata. We consider tree automata that recognize derived languages. For a word language L, the derived language of L, denoted L, is the set of all trees all of whose paths are in L. Since often we want to specify that all the computations of the program satisfy some property, the interest in derived languages is clear. Our main result shows that L is recognizable by a nondeterministic Büchi word automaton but not by a deterministic Büchi word automaton iff L is recognizable by a Rabin tree automaton and not by a Büchi tree automaton. Our result provides a simple explanation for the expressiveness gap between Büchi and Rabin tree automata. Since the gap between deterministic and nondeterministic Büchi word automata is well understood, our result also provides a characterization of derived languages that can be recognized by Büchi tree automata. Finally, it also provides an exponential determinization of Büchi tree automata that recognize derived languages. (shrink)

Cladism, now the dominant school of systematics, places organisms into groups depending just on their place in the tree of life. That is supposed to render classifica- tion objective. In section i, I recite claims to objectivity. In sections ii–v, I argue that the apparent objectivity is not what it seems to be. In section vi, I briefly revisit systematics. (shrink)

Tree branches near the electric power transmission lines are of great threat to the electricity supply. Nowadays, the tasks of clearing threatening tree branches are still mostly operated by hand and simple tools. Traditional structures of the multirotor aerial robot have the problem of fixed structure and limited performance, which affects the stability and efficiency of pruning operation. In this article, in order to obtain better environmental adaptability, an active deformable trees-pruning aerial robot is presented. The deformation of (...) the aerial robot is implemented through two ways, arm telescopic and folding. In order to suppress the influence of internal and external disturbances on the system, Active Disturbance Rejection Control technology is adopted to build the flight controller. Firstly, active deformation aerial robot structure is given, followed by system dynamic model establishment under wind disturbance using the Newton–Euler method. Also, the analysis of the gusts influence on the system is considered. Then, the active deformation aerial robot system is decoupled into a combination of six SISO systems, so that a disturbance rejection controller is designed. Finally, the expanded state observer and the nonlinear state error feedback law are used to inspect and compensate the disturbance. Simulation results of attitude and position tracking as well as the antidisturbance capability show that the active deformation aerial robot with the ADRC flight controller designed in this paper has excellent attitude control capabilities during flight and trees-pruning operation.

There is a continuing debate in the field of perceptual organization as to whether the locus of global processing is early or late perceptual, as previous studies have yielded contrary results. The conducted behavioural study explored this issue with the paradigm of collating global processing with other process of perceptual organization, namely illusory contours processing. Interaction between these two processes of perceptual organization would indicate that global processing has an early perceptual locus, whereas the lack of such interaction would suggest (...) the late perceptual locus of global processing. In experiment 1, the effect of global dominance was obtained with the use of a compound figure composed of geometrical shapes with real edges. Results showed that the processing of the figure at the global level was faster and that it disrupted the processing of the figures from the local level. In experiment 1b, the compound figure was composed of local geometrical shapes generated with the use of the line-end induced illusory contours. Local elements with illusory contours did not affect the processing of the hierarchical structure and the effect of global precedence occurred without any changes. In experiment 2a, a global advantaged effect within a compound figure with local elements with real edges was obtained in the paradigm of attention divided between levels of the hierarchical structure. When illusory contours of local elements of a compound figure were introduced to this paradigm, this again had no effect on the perceptual global advantage. The results demonstrate the lack of interaction between global processing and illusory contour processing, indicating that the locus of global processing is rather late perceptual. (shrink)

First delivered in French by Deleuze at the "Schizo-Culture" conference organized by Semiotext at Columbia University in 1975, "Rhizome" introduced a new kind of thinking in philosophy, both non-dialectical and non-hierarchical. The two didn't expect this neo-anarchical blue-print would eventually offer an early template for the understanding of the internet. "Rhizome" substitutes pragmatic, "couch grass," free-floating logic to the binary, oppositional, and exclusive model of the tree. In "Politics," superceding the Marxist concept of class, Deleuze envisages the social macrocosm (...) as a series of lines, and reinvent politics as a process of flux whose outcome will always be unpredictable. It is, he emphasizes, the end of the idea of revolution, but not of the "becoming revolutionary.". (shrink)

During the first decades of the 20th century, many anthropologists who had previously adhered to a linear view of human evolution, from an ape via Pithecanthropus erectus and Neanderthal to modern humans, began to change their outlook. A shift towards a branching model of human evolution began to take hold. Among the scientific factors motivating this trend was the insight that mammalian evolution in general was best represented by a branching tree, rather than by a straight line, and that (...) several new fossil hominids were discovered that differed significantly in their morphology but seemed to date from about the same period. The ideological and practical implications of imperialism and WWI have also been identified as formative of the new evolutionary scenarios in which racial conflict played a crucial role. The paper will illustrate this general shift in anthropological theory for one particular scientist, William Sollas. Sollas achieved a synthesis of human morphological and cultural evolution in what I will refer to as an imperialist model. In this theoretical framework, migration, conflict, and replacement became the main mechanisms for progress spurred by 'nature's tyrant,' natural selection. (shrink)

A rhizome may be broken, shattered at a given spot, but it will start up again on one of its old lines, or on new lines. You can never get rid of ants because they form an animal rhizome that can rebound time and again after most of it has been destroyed... There is a rupture in the rhizome whenever segmentary lines explode into a line of flight, but the line of flight is part of the rhizome. That is why (...) one can never posit a dualism or a dichotomy, even in the rudimentary form of the good and the bad. You may make a rupture, draw a line of flight, yet there still is a danger that you will stratify again everything, from Oedipal resurgences to fascist concretions. Groups and individuals contain microfascisms just waiting to crystallize. Yes, couch grass is also a rhizome.Edited by Sylvere Lotringer, On the Line was the first book published in the new "Foreign Agents" series in 1983.

A rhizome as subterranean stem is absolutely different from roots and radices. Bulbs and tubers are rhizomes... Even some animals are, in their pack forms. Rats are rhizomes. Burrows are too, in all their function of shelter, supply, movement, evasion and breakout... The rhizome includes the best and the worst: potato and couch grass. (shrink)

The onomasticon of Hellenistic Uruk demonstrates that, in some cases, individuals with Greek names were included in otherwise Babylonian families. Often, such Greek names have been interpreted by scholars as evidence for Hellenization. This article suggests an alternate explanation, based on evidence throughout the family trees for a series of naming practices that focus on the perpetuation of names of female relatives and transmission of preferred family names through maternal lines. Particularly important to this discussion are the practices of mammonymy, (...) a term coined here to refer to papponymy’s gendered parallel, i.e., the naming of a girl after her grandmother or other female ancestor, and the practice, previously unexamined in the Assyriological literature, of “maternal-line papponymy,” the tradition of naming a son for his maternal grandfather or other male ancestor from a maternal line. Maternal-line papponymy can be observed in family trees in which the members bear only Babylonian names, as well as in family trees that include individuals with Babylonian names and individuals with Greek names. The Greek names used for boys are often those of fathers or grandfathers of women with Greek names who married into these Babylonian families. This article argues that the incorporation of Greek names into the elite Babylonian families of Hellenistic Uruk cannot be assumed to be straightforward evidence of impulses toward “Hellenization.” Rather, this evidence indicates that Greek names were given to sons in such families within the context of traditional Babylonian maternal-line naming practices. This finding has important implications for scholarship’s understanding of acculturation and the display of cultural identity in Hellenistic Babylonia. (shrink)

The notion that plants, as well as animals, have a moral status is examined both in general, and with respect to the status of particularly rare plants that may be deemed to be lacking in general instrumentality, such as the Joshua tree. The work of Passmore, Singer and Santos is adduced, and several lines of argument revolving around preservation, sentiency and attractiveness to humans are constructed.

This paper discusses the issue of whether we have responsibilities to future generations with respect to genetic screening, including for purposes of selective abortion or discard. Future generations have been discussed at length among scholars. The concept of ‘Guardianfor Future Generations’ is tackled and its main criticisms discussed. Whilst germ-line cures, it is argued, can only affect family trees, genetic screening and testing can have wider implications. If asking how this may affect future generations is a legitimate question and since (...) we indeed make retrospective moral judgements, it would be wise to consider that future generations will make the same retrospective judgements on us. Moreover such technologies affect present embryos to which we indeed can be considered to have an obligation. (shrink)

There seems to be a minimal core that every theory wishing to accommodate the intuition that the future is open must contain: a denial of physical determinism (i.e. the thesis that what future states the universe will be in is implied by what states it has been in), and a denial of strong fatalism (i.e. the thesis that, at every time, what will subsequently be the case is metaphysically necessary).1 Those two requirements are often associated with the idea of an (...) objective temporal flow and the non-reality of the future. However, at least certain ways to frame the “openness” intuition do not rely on any of these. Branching Time Theory (BTT) is one such: it is compatible with the denial that time flow is objective and it is couched in a language with a (prima facie) commitment to an eternalist ontology. BTT, though, urges us to resist certain intuitions about the determinacy of future claims, which arguably do not lead either to physical determinism or to fatalism. Against BTT, supporters of the Thin Red Line Theory (TRL) argue that their position avoids determinism and fatalism, while also representing the fact that there is a future which is “special” because it is the one that will be the case. But starting with Belnap and Green 1994, some have objected to the tenability of TRL, mainly on metaphysical grounds. In particular, those argue that “positing a thin red line amounts to giving up objective indeterminism,”2 and that “has unacceptable consequences, ranging from a mistreatment of actuality to an inability to talk coherently about what would have happened had what is going to happen not taken place.”3 In this paper, we wish to reframe the..

The reconstruction of ensemble d–f of the Akhmîm Papyrus, better known as the Strasbourg Papyrus, which attests approximately eighteen of the over seventy new lines of Empedocles’ physical poem, has drawn the attention of scholars over recent years. Thanks to the good condition of the papyrus and the coincidence with two Empedoclean lines, already known from the indirect tradition, ensemble d–f 1–10a presents a well-restored text and an intelligible sense. In contrast, because of the damaged state of the papyrus, the (...) restoration of d–f 10b–18 is more complicated. These lines seem to describe a life-generative process, but what process was Empedocles talking about? Some resemblances between these papyrus lines and the lines of another Empedoclean fragment, DK 31 B 62, have suggested to scholars, notably to A. Martin and O. Primavesi in 1999 and M. Rashed in 2011, that the lines of the papyrus depict, just like DK 31 B 62, the generation of whole-natured beings. Other scholars, however, such as R. Janko in 2004 and A. Laks and G.W. Most in 2016, show more caution and leave the possibility open that Empedocles is here talking about the generation of something else. (shrink)

          The production of a number of vaccines involves the use of cell-lines originally derived from fetuses directly aborted in the 1960s and 1970s. Such cell-lines, indeed sometimes the very same ones, are important to on-going research, including at Catholic institutions. The cells currently used are removed by a number of decades and by a significant number of cellular generations from the original cells. Moreover, the original cells extracted from the bodies (...) of the aborted fetuses were transformed to produce the cell lines, since otherwise they would be incapable of the kind of culturing that is required.           It is generally acknowledged by ethicists, including many Catholic ones generally considered to be orthodox, and by the U.S. bishops, that the use of the cell-lines in connection with the production of vaccines is morally permissible. It does not appear that there is a relevant qualitative difference between the use of the cell-lines in vaccines and in research. One might argue that there is certainty of benefit from a vaccine while the benefits of research are uncertain. However, in any given case of the administration of a vaccine to an individual, it is far from certain that such administration will be of benefit to that individual. After all, the individual might never come in contact with someone infected with the disease in question, particularly if the disease is now uncommon in the individual’s locale. Yet, it is morally certain that some of the administrations of the vaccine will be beneficial. This is parallel to the fact that while any one research project might not be beneficial, the history of biomedical research makes it extremely probable, indeed morally certain, that some project involving the use of such cell-lines will be beneficial. There may, of course, be quantitative difference between the cases—the probabilities and benefits may not be equal—but the difference does not seem to be a qualitative one. Therefore, if one accepts the use of the cell-lines in vaccines, one should accept the use in research in at least some conceivable and perhaps actual circumstances.           The main argument I am interested in in favor of the use of the cell-lines proceeds by first granting that the initial abortion and extraction of cells from the deceased fetus was morally gravely illicit. However, the connection between the currently used derived cells and the abortion and original derivation is sufficiently remote that the use becomes licit. Not all fruit of a poisoned tree is poisoned: it can be morally....

The main purpose of this dissertation is to apply and develop new forcing techniques to obtain models where several cardinal characteristics are pairwise different as well as force many (even more, continuum many) different values of cardinal characteristics that are parametrized by reals. In particular, we look at cardinal characteristics associated with strong measure zero, Yorioka ideals, and localization and anti-localization cardinals.In this thesis we introduce the property “F-linked” of subsets of posets for a given free filter F on the (...) natural numbers, and define the properties “ $\mu $ -F-linked” and “ $\theta $ -F-Knaster” for posets in a natural way. We show that $\theta $ -F-Knaster posets preserve strong types of unbounded families and of maximal almost disjoint families. These kinds of posets led to the development of a general technique to construct $\theta $ - $\textrm {Fr}$ -Knaster posets (where $\textrm {Fr}$ is the Frechet ideal) via matrix iterations of ${<}\theta $ -ultrafilter-linked posets (restricted to some level of the matrix). The latter technique allows proving consistency results about Cichoń’s diagram (without using large cardinals) and to prove the consistency of the fact that, for each Yorioka ideal, the four cardinal characteristics associated with it are pairwise different. Another important application is to show that three strongly compact cardinals are enough to force that Cichoń’s diagram can be separated into 10 different values. Later on, it was shown by Goldstern, Kellner, Mejía, and Shelah that no large cardinals are needed for Cichoń’s maximum (J. Eur. Math. Soc. 24 (2022), no. 11, p. 3951–3967).On the other hand, we deal with certain types of tree forcings including Sacks forcing, and show that these increase the covering of the strong measure zero ideal $\mathcal {SN}$. As a consequence, in Sacks model, such covering number is equal to the size of the continuum, which indicates that this covering number is consistently larger than any other classical cardinal characteristics of the continuum. Even more, Sacks forcing can be used to force that $\operatorname {\mathrm{non}}(\mathcal {SN})<\operatorname {\mathrm{cov}}(\mathcal {SN})<\operatorname {\mathrm{cof}}(\mathcal {SN})$, which is the first consistency result where more than two cardinal characteristics associated with $\mathcal {SN}$ are pairwise different. To obtain another result in this direction, we provide bounds for $\operatorname {\mathrm{cof}}(\mathcal {SN})$, which generalizes Yorioka’s characterization of $\mathcal {SN}$ (J. Symbolic Logic 67.4 (2002), p. 1373–1384). As a consequence, we get the consistency of $\operatorname {\mathrm{add}}(\mathcal {SN})=\operatorname {\mathrm{cov}}(\mathcal {SN})<\operatorname {\mathrm{non}}(\mathcal {SN})<\operatorname {\mathrm{cof}}(\mathcal {SN})$ with ZFC (via a matrix iteration forcing construction).We conclude this thesis by combining creature forcing approaches by Kellner and Shelah (Arch. Math. Logic 51.1–2 (2012), p. 49–70) and by Fischer, Goldstern, Kellner, and Shelah (Arch. Math. Logic 56.7–8 (2017), p. 1045–1103) to show that, under CH, there is a proper $\omega ^\omega $ -bounding poset with $\aleph _2$ -cc that forces continuum many pairwise different cardinal characteristics, parametrized by reals, for each one of the following six types: uniformity and covering numbers of Yorioka ideals as well as both kinds of localization and anti-localization cardinals, respectively. This answers several open questions from Klausner and Mejía (Arch. Math.

International large-scale assessments, such as PISA, provide structured and static data. However, due to its extensive databases, several researchers place it as a reference in Big Data in Education. With the goal of exploring which factors at country, school and student level have a higher relevance in predicting student performance, this paper proposes an Educational Data Mining approach to detect and analyze factors linked to academic performance. To this end, we conducted a secondary data analysis and built decision trees (C4.5 (...) algorithm) to obtain a predictive model of school performance. Specifically, we selected as predictor variables a set of socioeconomic, process and outcome variables from PISA 2018 and other sources (World Bank, 2020). Since the unit of analysis were schools from all the countries included in PISA 2018 (n= 21,903), student and teacher predictor variables were imputed to the school database. Based on the available student performance scores in Reading, Math, and Science, we applied k-means clustering to obtain a categorized (three categories) target variable of global school performance. Results show the existence of two main branches in the decision tree, split according to the schools’ mean socioeconomic status (SES). While performance in high-SES schools is influenced by educational factors such as metacognitive strategies or achievement motivation, performance in low-SES schools is affected in greater measure by country-level socioeconomic indicators such as GDP, and individual educational indicators are relegated to a secondary level. Since these evidences are in line and delve into previous research, this work concludes by analyzing its potential contribution to support the decision making processes regarding educational policies.

An influential line of thought in metaphysics holds that where common sense discerns a tree or a dog or a baseball there may be just many microparticles. Provided the microparticles are arranged in the right way—are “treewise” or “dogwise” or “baseballwise” arranged—our sensory experiences will be just the same as if a tree or dog or baseball were really there. Thereforewhetherthere really are such familiar objects in the world can be decided only by determining whatmoreis needed for microparticles (...) dogwise arranged actually tocomposea dog. This paper argues that this line of thought sets up the wrong agenda. Composition is trivial; dogwise (etc.) arrangement is tricky. Dogwise arrangement will obtain in the wrong regions unless we stipulate that there are dogs, and that dogwise arrangement obtains only within their borders. The bearers of dogwise arrangement, moreover, will have to be dogs themselves, not their microparticles. Thus allowing that dogwise arrangement obtains at all is allowing that there are dogs.

We introduce a suitable notion of eight-shaped curve in the product S × ℝ of a Suslin line S for the real line ℝ, and we prove that if S is dense in itself, then every collection of pairwise disjoint eight-shaped curves in S × ℝ is countable. This parallels a folklore result which holds for the real plane.

In this contribution, I explore the possibility of characterizing the emergence of time in causal set theory (CST) in terms of the growing block universe (GBU) metaphysics. I show that although GBU seems to be the most intuitive time metaphysics for CST, it leaves us with a number of interpretation problems, independently of which dynamics we choose to favor for the theory —here I shall consider the Classical Sequential Growth and the Covariant model. Discrete general covariance of the CSG dynamics (...) does not allow us to individuate a single history of the universe (defined by a causal history of different causal sets), thereby making the claim that ‘the past exists’ at best problematic. In addition, because the evolution of the universe in CSG dynamics leads to an outward branching causal tree, it becomes impossible to determine a proper ‘line of becoming’, thereby blurring the presentists’ claim that only the present exists. Similarly, the covariant approach runs into the same, if not even more severe problems, since each configuration of the universe would amount to a set of possible causal sets, thereby making the individuation of a single configuration of the universe —and thus the physical interpretation of the theory— implausible.

Sheikh Halid Sufi, as a Sufi poet, addresses human being as the main subject of his sufist dicourse. He is an important figure of our recent history as he primarily adopted the goal of human perfection and revealed a doctrine of humanity in the school of knowledge. In advance of our current century, when human is seen just in physical respect, he lived as a man of heart who handled human being with an integrated approach within the aspects of matter (...) and spirituality, the world and the hereafter, individual and community, body and soul. In this communiqué, I will discuss Sheikh Halid Effendi’s ontology and his point of view on the place of human being in the realm of existence. He seeks human perfection and wishes people to free themselves of shabby desires and regain their disposition. He recommends people to achieve purity in order to reach the rank of being a mirror to God’s reflections. As a Sufi poet, he attaches importance to carrying out the education of divine journey, wrapping up in mystical ethics, having the identity of wisdom and gaining the aesthetics of love so as to reach the perfection. SUMMARY Sheikh Mehmed Halid was born in 1273/1856 in Sivas. He graduated from Ottoman Junior High School. He attended the 1893 War. In 1880, he started his professional career at a state office. Until 1899, he served in several positions, as assistant judge in Erbaa Lower Court, as Prosecuting Deputy Attorney in Sivas, as Prosecuting Judge assistant in Lower Court and head clerk in Darende, as head clerk in Lower Court in Tonus/Altınyayla, and as prosecuting judge in Kuruçay. He died in 1931 and was buried in Sivas Yukarı Tekke Graveyard. Sufism (tasawwuf) is an education for integrity towards maturity, in a way to prufiy the self from evils of nafs (self) and to reach the love of Allah. This spiritual educational journey is called ‘Seyr-u Suluk’. Sheikh Mehmed Halid completed his Seyr u Suluk as a dervish (student) of murshid (mentor) Kastamonulu Ganizade Mehmed Sadık Baba. Sheikh Mehmed Halid wrote three books called Hilafetnāme, Mektubāt, and Divan. He deals with issues of Sufism (mysticism) in these works. Primarily, his works dwells into the matters of morals, worship, good manners (adab), customary practices, ingenuity, existence, and love. Sheikh Mehmed Halid’s sole attempt is to explain the relationship among Allah, man and universe in an understandable way. According to Sheikh Mehmed Halid’s conception of Sufism, existence is unique and that existence is only Allah. The existence of Allah is absolute while the existence of assets is relative. Things do not exist on their own. Universe is like a mirror. What is reflected in the mirror of universe are the shadows of Allah the Omnipotent. The graces of The Divine are reflected in this mirror. All the things that exist in the universe proves the Self of Allah and his properties. Each of the things in the universe are the words of Allah. The existence of the universe is a result of Allah’s mercy. Man is the fruit of the tree of the Universe.Man is both the embodiment and the reflection of Allah. We want to discuss the position of man in between Allah and the universe with Sheikh Halid’s verses. Perceiving plurality in unity and unity in plurality, Sheikh Mehmed Halid attributes the variety of things and existence in the universe to the Divine beauties of Allah. For those who can comprehend, the plurality/ abundance in existing objects in the universe indicates singularity and uniqueness of Allah. According to Sheikh Halid, Allah is independent from and beyond all the entities that exist in the universe. However, Allah, manifests Himself in the things that he creates and the actions he takes through His divine names and properties. According to Sheikh Halid, each object is a reflection of Allah’s divine properties. Every entity in the universe glorifies Allah with all their existence. For Sheikh Halid, Seyr u Suluk is the journey from weakness to perfection, from substance to meaning, and from things to reality. Considering Seyr u Suluk education as distancing one’s self from other beings, reaching purity of heart, disposing of all signs explains these concepts with pilgrimage metaphor. As a response to those who asks him what he meant by seyr u suluk, he says seyr u suluk is servitude and submission to Allah. In order for Seyr u Suluk to be meaningful, a person should enter the way of a murshid-i kāmil (perfect religious mentor), and should have sincerity, purity (being deprived of all sins) and dhikr. According to Sheikh Halid, someone who is not in trouble is not given a remedy. So as to bother is necessary for remedy to be arisen. Nuisances of the universe are also ephemeral as the universe itself. Therefore, it is unnecessary to bother things that are ephemeral. Because remedy is not available without being mature. According to Sheikh Halid, the procedure of gaining advantage from being mature; getting rid of the ego, feeling the love, being pioneer of the mission, being modest, to attain soul pleasure, escaping from fame, leaving the claim, the glory of salvation, proceeding dhikr, reaching the conquests and escaping from friendship of worldly things. According to Sheikh Halid, being mature is not setting about affiliation ceremony. Asceticism cannot be a show and claim authority. Sincerity is needed on the basis of seyr u suluk education. Asceticism which is an effort of making the religion a specific of Allah is to make intimacy with Allah. Sheikh Halid wants his murids who take part in ṭarīqa (sufī path) to decide on the sincerity. Sincerity is said to be the unique factor that makes sense the membership. Seyr u suluk which begins with being membership of mature murshid, which makes sense with proceeding worship and respecting the sincerity arises by teaching manners to soul. Seyr u suluk is trying to reform the soul. Teaching manners to soul is a challenging and significant task. The most important factor that ensure teaching manners to the soul to be achieved is dhikr. Dhikr practice which makes successful the teaching manner to the soul of seyr u suluk training increases the prudence and foresight of dervish. The unique task that murshid expects from his murid during the membership process is to adjust his soul and parlance to the dhikr of Allah. Dhikr of Allah is a product of fondness. According to Sheikh Halid, one who wants to be remembered in heaven should himself learn to remember Allah. Sheikh Halid gives too much importance to disciplining the tariqa where sufi training takes place. A murid should qualify his murshid whom he intimated to. Followers should gain sufficient advantage from the spiritual atmosphere in the dergāh of their murshid. The murid must be at the service of the murshid who trains him and should obey tariqa manners. Salik who achieves seyr u suluk, who maturates the sufi ethics and who gains sincerity through dihkr of Allah tries to achieve the Gnosis. The intent of being a human is to know Allah. The biggest disaster for human is to come upon unawareness. Sheikh Halid who assumes the the Arifs as sultans of walayah makes a comparison between the Arifs and the Zahids and prefers the Arifs. He thinks that the Zahids pay attention to the appearance, cannot reach the basis and cannot go beyond Allahliness show. Sheikh Halid, who encourages the Zahids to avoid comparing themselves with the Arifs, warns the ones who combat with the Arifs and reminds that Allah proclaims warfare to those who has hostility towards those surrendering themselves to Allah. Sheikh Halid lines up the ways of being mature and having wisdom as godly grace, asceticism, love, the mind of leaving, battle with the self, humility, dikhr and being woeful. Salvation process which Marifetullah will guide is to achieve the love of Allah. Love is the way of achieving the reunion. The reality can just be gained through love. However, gaining the divine love requires to be loved. Because, the way of gaining the divine love is to remove everything except Allah from one’s heart. (shrink)

The institutionalization of ethics is an important task for today's organizations if they are to effectively counteract the increasingly frequent occurrences of blatantly unethical and often illegal behavior within large and often highly respected organizations. This article discusses the importance of institutionalizing organizational ethics and emphasizes the importance of several variables (psychological contract, organizational commitment, and an ethically-oriented culture) to the institutionalization of ethics within any organization.... institutionalizing ethics may sound ponderous, but its meaning is straightforward. It means getting ethics (...) formally and explicitly into daily business life. It means getting ethics into company policy formation at the board and top management levels and through a formal code, getting ethics into all daily decision making and work practices down the line, at all levels of employment. It means grafting a new branch on the corporate decision tree — a branch that reads right/wrong (Purcell and Weber, 1979, p. 6). (shrink)

In his recent book, Daniel Korman contrasts ontological conservatives with permissivists and eliminativists about ontology. Roughly speaking, conservatives admit the existence of ‘ordinary objects' like trees, dogs, and snowballs, but deny the existence of ‘extraordinary objects', like composites of trees and dogs. Eliminativists, on the other hand, deny many or all ordinary objects, while permissivists accept both ordinary and extraordinary objects. Our aim in this paper is to outline some of our reasons for being drawn to permissivism, as well as (...) some of our misgivings about conservative metaphysics. In the first section, we discuss a tempting epistemic line of argument against conservatism. This isn’t a line of argument we find especially promising. Our most basic complaint against conservatism is not that conservatism has poor epistemic standing even if true, but instead that conservatism is weird. We develop this thought in the second part of the paper. In the final section we discuss some larger methodological issues about the project of ontology. (shrink)

The Brooks Range, one of the most remote and least-disturbed wildernesses of North America, is immense and inaccessible enough to earn a nearly mythic reputation. Dennis Witmer’s splendid volume, Far to the North: Photographs from the Brooks Range explores the limits of the tree line that juts through the southern edge of the range, revealing northern peaks and valleys bare of vegetation and glossed over by a softening snow that can arrive at any time of the year. A magnificent (...) glimpse at nature in its most pristine and raw form, the epic photography featured in Far to the North will be a welcome addition to the collection of any explorer or lover of the northern landscape.

According to perceptualism, fluent comprehension of speech is a perceptual achievement, in as much as it is akin to such high-level perceptual states as the perception of objects as cups or trees, or of people as happy or sad. According to liberalism, grasp of meaning is partially constitutive of the phenomenology of fluent comprehension. I here defend an influential line of argument for liberal perceptualism, resting on phenomenal contrasts in our comprehension of speech, due to Susanna Siegel and Tim Bayne, (...) against objections from Casey O'Callaghan and Indrek Reiland. I concentrate on the contrast between the putative immediacy of meaning-assignment in fluent comprehension, as compared with other, less ordinary, perhaps translation-based ways of getting at the meaning of speech. I argue this putative immediacy is difficult to capture on a non-perceptual view (whether liberal or non-liberal), and that the immediacy in question has much in common with that which applies in other, less controversial cases of high-level perception.

Progress Unchained reinterprets the history of the idea of progress using parallels between evolutionary biology and changing views of human history. Early concepts of progress in both areas saw it as the ascent of a linear scale of development toward a final goal. The 'chain of being' defined a hierarchy of living things with humans at the head, while social thinkers interpreted history as a development toward a final paradise or utopia. Darwinism reconfigured biological progress as a 'tree of (...) life' with multiple lines of advance not necessarily leading to humans, each driven by the rare innovations that generate entirely new functions. Popular writers such as H. G. Wells used a similar model to depict human progress, with competing technological innovations producing ever-more rapid changes in society. Bowler shows that as the idea of progress has become open-ended and unpredictable, a variety of alternative futures have been imagined. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 8.2 (2003) 106-125 [Access article in PDF] Leopold's NovelThe Land Ethic in Barbara Kingsolver's Prodigal Summer Peter S. Wenz Introduction Like many good novels, Prodigal Summer's 1 account of love, tragedy, conflict, and choice in human relationships conveys an overall message about how life should be lived. In this case the message corresponds to Aldo Leopold's call for "a land ethic [that] changes the role (...) of Homo sapiens from conqueror of the land-community to plain member and citizen of it." People should "respect... fellow-members and also... the community as such." 2 Barbara Kingsolver explains Leopold's key ideas and updates the Land Ethic by showing how it might guide people today. The present paper selectively displays this relationship, and then suggests some pedagogical advantages of fiction.Prodigal Summer tells three interconnected stories that take place from May through July one year in contemporary rural Kentucky. One story features Deanna Wolfe, who has spent the last 25 months working for the U.S. Forest Service in a wilderness area on Zebulon Mountain where she restores trails and impedes illegal hunting. She has just discovered that coyotes have arrived, but so has Eddie Bondo, a handsome man from the West who hates coyotes because they sometimes kill livestock. [End Page 106]Another story features Lusa Landowski and her husband Cole Widener. Lusa is an entomologist who taught at the University of Kentucky before marrying Cole and moving to his family's tobacco farm that adjoins the national forest where Deanna works. Cole dies early in the novel and Lusa tries to save the family farm.Finally, Nannie Rawley is a senior citizen who grows organic apples nearby and has conflicts with her more senior neighbor, Garnett Walker, who wants to kill weeds with chemicals to keep his property looking neat. Garnett's goal is to cross-fertilize chestnut trees to create an American chestnut that is immune to chestnut blight. Ecocentrism, Hunting, the Biotic Pyramid, and Exotic Species Aldo Leopold's Land Ethic is famously holistic and ecocentric. The ecosystem, a holistic entity, has value over and above, and in most cases more than, the value of its individual components. This ecocentric perspective is summed up in the maxim: "A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise" (1970, 262).Ecocentrism explains Leopold's attitude toward hunting. In many passages, such as the October account of hunting ruffed grouse (58-62) and partridge (62-69), Leopold describes the hunt with approval. However, he disapproves of programs to eradicate keystone predators because their elimination impoverishes ecosystems. His classic account, "Thinking Like a Mountain," concerns wolf eradication. He writes, "I thought that because fewer wolves meant more deer, that no wolves would mean hunters' paradise" (138). But he found that wolf eradication harms mountains, that is, ecosystems. I have watched the face of many a newly wolfless mountain, and seen the south-facing slopes wrinkle with a maze of new deer trails. I have seen every edible bush and seedling browsed, first to anaemic desuetude, and then to death. I have seen every edible tree defoliated to the height of a saddle horn.... In the end the starved bones of the hoped-for deer herd, dead of its own too-much, bleach with the bones of the dead sage, or molder under the high-lined junipers. (139-40) Leopold's concept of a biotic pyramid explains why wolf eradication harms ecosystems. According to Leopold, the energy that plants absorb from the sun: [End Page 107]... flows through a circuit called the biota, which may be represented by a pyramid consisting of layers. The bottom layer is the soil. A plant layer rests on the soil, an insect layer on the plants, a bird and rodent layer on the insects, and so on up through the various animal groups to the apex layer, which consists of the larger carnivores.... Proceeding upward, each successive layer decreases in numerical... (shrink)

There is a time of day immediately before dusk when the outline of every object becomes sharply delineated. It was just that moment. The lacerated edges of wooden beams in the wreckage, the freshness of the rents in the shredded trees, and the curled zinc sheets with their puddles of rain water - everything appeared almost unpleasantly vivid. In the extreme west only a horizontal line of scarlet was to be seen in the sky between two or three towering black (...) burned-out buildings. Flecks of scarlet were also visible through the windows of the ruined structures. It was as if someone had turned on a red light in a deserted and uninhabited house.

A new view of the functional role of the left anterior cortex in language use is proposed. The experimental record indicates that most human linguistic abilities are not localized in this region. In particular, most of syntax (long thought to be there) is not located in Broca's area and its vicinity (operculum, insula, and subjacent white matter). This cerebral region, implicated in Broca's aphasia, does have a role in syntactic processing, but a highly specific one: It is the neural home (...) to receptive mechanisms involved in the computation of the relation between transformationally moved phrasal constituents and their extraction sites (in line with the Trace-Deletion Hypothesis). It is also involved in the construction of higher parts of the syntactic tree in speech production. By contrast, basic combinatorial capacities necessary for language processing – for example, structure-building operations, lexical insertion – are not supported by the neural tissue of this cerebral region, nor is lexical or combinatorial semantics. The dense body of empirical evidence supporting this restrictive view comes mainly from several angles on lesion studies of syntax in agrammatic Broca's aphasia. Five empirical arguments are presented: experiments in sentence comprehension, cross-linguistic considerations (where aphasia findings from several language types are pooled and scrutinized comparatively), grammaticality and plausibility judgments, real-time processing of complex sentences, and rehabilitation. Also discussed are recent results from functional neuroimaging and from structured observations on speech production of Broca's aphasics. Syntactic abilities are nonetheless distinct from other cognitive skills and are represented entirely and exclusively in the left cerebral hemisphere. Although more widespread in the left hemisphere than previously thought, they are clearly distinct from other human combinatorial and intellectual abilities. The neurological record (based on functional imaging, split-brain and right-hemisphere-damaged patients, as well as patients suffering from a breakdown of mathematical skills) indicates that language is a distinct, modularly organized neurological entity. Combinatorial aspects of the language faculty reside in the human left cerebral hemisphere, but only the transformational component (or algorithms that implement it in use) is located in and around Broca's area. Key Words: agrammatism; aphasia; Broca's area; cerebral localization; dyscalculia; functional neuroanatomy; grammatical transformation; modularity; neuroimaging; syntax; trace deletion. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 8.1 (2003) 51-56 [Access article in PDF] KarraKarrawirraparri-River Red Gum-Eucalyptus Camaldulensis Vivonne Thwaites [Figures]Karra was a visual arts project devised for the 2000 Adelaide Festival in Australia. Its focus was the River Red Gum, quite justifiably an Australian icon, and once the most widespread tree in south eastern Australia. The project comprised an installation by three artists and a forty-page publication with essays and (...) visual material from many contributors.The intention of the project (which I developed and oversaw as curator) was twofold. First, I hoped that an examination of the River Red Gum from a number of points of view might help people connect with the tree itself, and more broadly with this place non-Aboriginal Australians so uneasily inhabit. Second, given the tree's central place in Australia's inland waterways, I wanted the art to help people consider the urgent problems facing this ecosystem, such as increased salinity, diminished water flow and environmental degradation. This subject had particular relevance for South Australians, as our state is so dependent on the Murray-Darling River system. For example, in February 1999 the Commonwealth Scientific and Industrial Research Organisation published a media release on "Salt: Australia's Greatest Battle," declaring that we stand to lose a large fraction of our native biodiversity to salinity, and that native tress "remain the front line answer." [End Page 51]Behind the Festival Centre lies the River Torrens and the Adelaide Plains. Along the river are several gnarled old trees, River Red Gums, some of them predating white settlement and bearing the scars of Aboriginal timber collecting activities. The media was full of stories about the way these trees were still being cut down along the Murray further out, regardless of their proven value in filtering water and reducing salinity. The theme of the 2000 Festival was "The New Out of the Old," and it seemed that a project about the relevance of these beautiful old trees would help educate and inspire. We found the subject for the Festival project right in our own backyard.Once committed to the subject, research could begin. First up was the tree's Aboriginal history. The Kaurna people, original inhabitants of the Adelaide Plains, called it Karra or more fully, Karrawirraparri (literally 'redgum-forest-river'). The tree was central to their lives as source of food and shelter, and supplier of timber for shields and other implements. There are incised shields of Red Gum in the South Australian Museum, and delicate drawings of the tree by Jim Kite. The tree's place in Australia's white history can be traced back to explorer's journals where, variously named, it was described as a welcome sign of the presence of a watercourse. More recently it appears in the natural history writing of Eric Rolls and others (Rolls 2002). Ironically the tree's botanical name, Eucalyptus camaldulensis, originated in 1832, when a botanist admired and named a single specimen grown by monks outside Naples, Italy. The eucalyptus was already spreading in 1832.Early in the research it became clear that the Red Gum tree, and the complex set of natural and cultural interactions it engendered, could be seen as a symbol of human interactions with the land in Australia. The tree was much discussed and much loved by Australians, but also much abused. It seemed that bringing together different systems of understanding and representation of the tree could help contemporary urban Australians begin to understand their own connections to it, and to the land as well. This was the broader cultural agenda of the project.Preparing the art exhibition required a wide reading of literature. Les Murray's poem, "The Gum Forest," one of the greatest 20th - century Australian poems, was inspirational: After the last gapped wire on a post, homecoming for me, to enter the gum forest. (1998, 33) [End Page 52] [Begin Page 54]So too was Murray Bail's book Eucalyptus: By sheer numbers there's always a bulky Red Gum here or somewhere else in the wide world, muscling into the...

An original deep history of the internet that tells the story of the centuries-old utopian dreams behind it—and explains why they have died today Many think of the internet as an unprecedented and overwhelmingly positive achievement of modern human technology. But is it? In The Internet Is Not What You Think It Is, Justin Smith offers an original deep history of the internet, from the ancient to the modern world—uncovering its surprising origins in nature and centuries-old dreams of radically improving (...) human life by outsourcing thinking to machines and communicating across vast distances. Yet, despite the internet’s continuing potential, Smith argues, the utopian hopes behind it have finally died today, killed by the harsh realities of social media, the global information economy, and the attention-destroying nature of networked technology. Ranging over centuries of the history and philosophy of science and technology, Smith shows how the “internet” has been with us much longer than we usually think. He draws fascinating connections between internet user experience, artificial intelligence, the invention of the printing press, communication between trees, and the origins of computing in the machine-driven looms of the silk industry. At the same time, he reveals how the internet’s organic structure and development root it in the natural world in unexpected ways that challenge efforts to draw an easy line between technology and nature. Combining the sweep of intellectual history with the incisiveness of philosophy, The Internet Is Not What You Think It Is cuts through our daily digital lives to give a clear-sighted picture of what the internet is, where it came from, and where it might be taking us in the coming decades.
