Contemporary architecture is increasingly grounded in science and mathematics. Architectural discourse has shifted radically from the sometimes disorienting Derridean deconstruction, to engaging scientific terms such as fractals, chaos, complexity, nonlinearity, and evolving systems. That's where the architectural action is -- at least for cutting-edge architects and thinkers -- and every practicing architect and student needs to become conversant with these terms and know what they mean. Unfortunately, the vast majority of architecture faculty are unprepared to explain them to students, not (...) having had a scientific education themselves. Here is an architecture book by an architect/scientist, just in time to help architects in the new millennium. Alexander discusses many of the scientific terms arising in cutting-edge architecture, and explains them to those who don't have scientific training or advanced mathematical knowledge. We find discussions of the evolution of forms; the importance of process in design; iteration; genetic algorithms; sequences of transformations; different levels of scale (i.e. fractals); etc. They are explained here by an architect who is also a scientist, because he wants to change the way architects think and build. Alexander is not merely popularizing other scientists' results and making them accessible to architects: he is in fact presenting new and original scientific work that ties many of these concepts together in a way that will be useful to architects.

The purpose of this study is to analyse the structure of written argumentative texts produced by pupils in grades 3, 5, 7 and 11 in relation to three different tasks: Group A — subjects are assigned a topic question consisting of a single statement ; Group B — subjects are given a topic question consisting of both a statement and its opposite ; Group C — subjects are given an initial and a final sentence of a text, which they have (...) to complete, and which refers to opposite opinions . Six different types of text organization were evidenced on the basis of the argumentative moves presented in the texts, the linguistic indexes used to express the relationships between the moves, the presence or absence of counter-arguments and the type of argumentation or reasoning used. The organization of the texts range from a simple affirmation of a position to a use of data or reasons to support a position, to others still in which two positions are presented in the body of a unitary structure, developed ‘in parallel’ and interconnected regularly. Our analysis found a well-defined tendency corresponding to the age levels in the types of texts produced by the subjects. The texts produced by the younger group, the pupils in elementary school, contained a fairly simple structural organization, characterized by very few argumentations or a lack of explicitness of the essential moves and a juxtaposing of arguments. The older subjects, in particular those attending secondary school, were able to produce texts which were more complex with regard to the presence and the organization of the argumentative moves, and more coherent and cohesive with respect to their articulation of opinions and use of adequate linguistic indices to analyze t topic. As regards the different types of tasks, when the subjects were presented explicitly with two opposite opinions , they developed both positions in their responses, contrary to the situation in which they produced one position when only one of two opinions was presented.

The purpose of this study is to analyse the structure of written argumentative texts produced by pupils in grades 3, 5, 7 and 11 in relation to three different tasks: Group A — subjects are assigned a topic question consisting of a single statement (open question); Group B — subjects are given a topic question consisting of both a statement and its opposite (opposite opinions); Group C — subjects are given an initial and a final sentence of a text, which (...) they have to complete, and which refers to opposite opinions (oriented task). Six different types of text organization were evidenced on the basis of the argumentative moves presented in the texts, the linguistic indexes used to express the relationships between the moves, the presence or absence of counter-arguments and the type of argumentation or reasoning used. The organization of the texts range from a simple affirmation of a position (repitition of the proposition or its opposition without any support) to a use of data or reasons to support a position, to others still in which two positions are presented in the body of a unitary structure, developed ‘in parallel’ and interconnected regularly.

Das Verhältnis von Lebenswelt und Wissenschaft befindet sich mit ungewissem Ausgang in stetiger Bewegung. In diesem Prozess ist das treibende Element die Wissenschaft, die Technisierungen ermöglicht und mit ihren Erkenntnissen die Welt überzieht. Trotz der fortschreitenden Verwissenschaftlichung hat sich die Lebenswelt jedoch ihre Eigenständigkeit bewahrt. Die vorliegenden Studien tragen zur Aufklärung dieses erstaunlichen Phänomens bei. Sie weisen Strukturdifferenzen der beiden Erfahrungsweisen auf und zeigen, wie sie mit- und gegeneinander existieren. Zugleich wird deutlich, dass ein Ende der lebensweltlichen Eigenständigkeit einen (...) fundamentalen Wandel für die gesellschaftliche Stellung nichtwissenschaftlicher Erfahrung bedeuten würde. Die Untersuchungen sind begrifflich, wissenschaftstheoretisch und phänomenologisch orientiert. Sie gehen von einem weitgefassten Wissenschaftsbegriff aus, der auch Technikwissenschaften sowie wissenschaftliche Anwendungen umfasst. In den Fallbeispielen kommt den Naturwissenschaften und dem Naturbegriff eine besondere Aufmerksamkeit zu. Der Lebensweltbegriff schließt in kritischer Distanz an die Sozialphänomenologie von Alfred Schütz und die Phänomenologie Edmund Husserls an. (shrink)

In this paper, I argue for what I define as the multiplicity thesis. According to MT, there is not a single public of public art, but a multiplicity of them. I defend MT both as a descriptive and a normative claim. I explore different types of publics of public art that can be distinguished from one another in terms of their different sizes. I expand my analysis of the differences among separate publics of public art by considering temporary and (...) enduring ones. (shrink)

In this paper, I offer an account of the structural differences, neglected in the literature, between Dietrich Bonhoeffer and Emmanuel Levinas, showing how Bonhoeffer’s account of persons and responsibility is differentiated through creation, fall, and redemption, whereas Levinas’s account of ethical selfhood offers itself as a kind of transcendental account of persons in which the self is structured by its encounter with the other which commands responsibility. This difference (situationally differentiated vs. transcendental) plays out in two ways – (...) the role of the will in ethical selfhood and the identity of the primal governing agent in the encounter with others. Bonhoeffer’s account, through its differentiation into different modes of existence, allows for the possibility of different stages and modes of the encounter with the other, and thus allows for the incorporation of one model of encounter at one stage, and another model at a different stage. As a consequence, Bonhoeffer’s account includes and develops upon the kind of demand-based account Levinas offers. This can serve as an advantage over Levinas’s model insofar as it provides a ‘multi-modal’ framework to absorb other views into one’s own in a way that a transcendentally conceived framework of selfhood does not.

Decision-making under normative uncertainty requires an agent to aggregate the assessments of options given by rival normative theories into a single assessment that tells her what to do in light of her uncertainty. But what if the assessments of rival theories differ not just in their content but in their structure -- e.g., some are merely ordinal while others are cardinal? This paper describes and evaluates three general approaches to this "problem of structural diversity": structural enrichment, structural (...) depletion, and multi-stage aggregation. All three approaches have notable drawbacks, but I tentatively defend multi-stage aggregation as least bad of the three. (shrink)

The expression of physical motion (the spider crawls across the net) and metaphorical motion (the fear crawls across her heart) shows strong inter-typological differences between language types (German, an S-language vs. Spanish, a V-language) and more subtle intra-typological differences within a language type (German vs. Polish, both S-languages). However, we know relatively less about the extension of these patterns to translated texts. In this study, we focused on physical and metaphorical motion descriptions in written texts in original language (...) and their translations to a language that belongs to the same or a different typological group, to determine whether motion expression in translated texts shows the same patterns of inter-typological and intra-typological variability as it does in original texts. We investigated this question by extracting 450 physical motion (150/language) and 450 metaphorical motion (150/language) descriptions from novels originally written in German, Polish, or Spanish and their translations to typologically different (i.e. inter-typological; German to Spanish, Spanish to German) or typologically similar (i.e. intra-typological; German to Polish, Polish to German) languages. Our results provided evidence for similar patterns of strong inter-typological and more subtle intra-typological variability in translations akin to those observed in original texts – with translated texts largely following the patterns of the target language in their expression of physical and metaphorical motion. Our results also highlighted specificity of event expression in a language as an important factor in the attainment of target language patterns in translated texts. (shrink)

This paper centers around the notion that internal, mental representations are grounded in structural similarity, i.e., that they are so-called S-representations. We show how S-representations may be causally relevant and argue that they are distinct from mere detectors. First, using the neomechanist theory of explanation and the interventionist account of causal relevance, we provide a precise interpretation of the claim that in S-representations, structural similarity serves as a “fuel of success”, i.e., a relation that is exploitable for the (...) representation using system. Then, we discuss crucial differences between S-representations and indicators or detectors, showing that—contrary to claims made in the literature—there is an important theoretical distinction to be drawn between the two.

Over the last decade, iterated learning studies have provided compelling evidence for the claim that linguistic structure can emerge from non‐structured input, through the process of transmission. However, it is unclear whether individuals differ in their tendency to add structure, an issue with implications for understanding who are the agents of change. Here, we identify and test two contrasting predictions: The first sees learning as a pre‐requisite for structure addition, and predicts a positive correlation between learning accuracy and structure addition, (...) whereas the second maintains that it is those learners who struggle with learning and reproducing their input who add structure to it. This prediction is hard to test in standard iterated learning paradigms since each learner is exposed to a different input, and since structure and accuracy are computed using the same test items. Here, we test these contrasting predictions in two experiments using a one‐generation artificial language learning paradigm designed to provide independent measures of learning accuracy and structure addition. Adults (N = 48 in each study) were exposed to a semi‐regular language (with probabilistic structure) and had to learn it: Learning was assessed using seen items, whereas structure addition was calculated over unseen items. In both studies, we find a strong positive correlation between individuals' ability to learn the language and their tendency to add structure to it: Better learners also produced more structured languages. These findings suggest a strong link between learning and generalization. We discuss the implications of these findings for iterated language models and theories of language change more generally.

The fructose 6-phosphate (Fru-6P) saturation curve for phosphofructokinase (PFK) from E. coli is sigmoidal in the presence of saturating MgATP levels, while the corresponding curve for B. stearothermophilus PFK is essentially hyperbolic. Sigmoidality can be due to apparent cooperativity arising from the kinetic mechanism of an enzyme. We have determined the kinetic mechanism of B. stearothermophilus PFK (BsPFK). BsPFK was found to obey a non rapid-equilibrium random mechanism similar to the one E. coli PFK (EcPFK) follows. Substrate inhibition by MgATP (...) was observed. We propose that substrates bind to BsPFK through two alternative pathways, one of which is slower. The substrate inhibition arises in part from reaction flux through the slower pathway. Although EcPFK and BsPFK obey similar kinetic mechanisms, they are inhibited differently by MgATP: EcPFK is profoundly inhibited, BsPFK only weakly. The structural basis for this difference could be closure of the active site via a conformational transition that occurs in EcPFK, but not BsPFK. To investigate the importance of this transition for MgATP inhibition of EcPFK, we have constructed a chimeric enzyme (ChiPFK) that contains the "rigid" ATP-binding domain of BsPFK grafted onto the remainder of the EcPFK subunit. Our results indicate that ChiPFK is locked in an "open" structure resembling the activated form of EcPFK. It is insensitive to heterotropic regulation. Nevertheless, ChiPFK exhibits residual cooperativity. Possible explanations for the cooperativity are discussed. The 6F loop is proposed to be important in PFK allosteric behavior. Residues along the loop are largely conserved between BsPFK and EcPFK, except for 161, which is a glutamate in BsPFK, and a glutamine in EcPFK. Using site-directed mutagenesis, Glu 161 of BsPFK has been changed to glutamine and alanine. Similarly, Gin 161 of EcPFK has been changed to glutamate, arginine and alanine. Of the five mutants, one, QA161, was particularly interesting. Though activated normally by GDP, it was completely insensitive to PEP inhibition. This indicates that the hydrogen-bonding ability of residue 161 is critical for PEP inhibition of EcPFK, and that GDP activation and PEP inhibition follow different structural pathways. (shrink)

We exhibit a structural difference between the truth-table degrees of the sets which are truth-table above 0′ and the PTIME-Turing degrees of all sets. Though the structures do not have the same isomorphism type, demonstrating this fact relies on developing their common theory.

Some philosophers have offered structural representations as an alternative to indicator-based representations. Motivating these philosophers is the belief that an indication-based analysis of representation exhibits two fatal inadequacies from which structural representations are spared: such an analysis cannot account for the causal role of representational content and cannot explain how representational content can be made determinate. In fact, we argue, indicator and structural representations are on a par with respect to these two problems. This should not be (...) surprising, we contend, given that the distinction between indicator and structural representations is better conceived as one involving degree rather than kind. (shrink)

This paper investigates the acquisition of residual verb second (V2) in three corpora consisting of data from Norwegian-English bilinguals (Emma, Emily, and Sunniva) in order to determine to what extent these structures are affected by cross-linguistic influence (CLI) from Norwegian V2. The three girls exhibit three different patterns with regard to the relevant constructions. They are very target-like in their use of auxiliaries in the relevant structures. However, when it comes to do-support, Emily and Sunniva are equally target-like, while Emma (...) mainly produces non-target-like structures. These either involve the omission of do, or non-target-like movement of a lexical verb. Furthermore, Emma also allows verb movement across the subject with both lexical verbs and auxiliaries in topicalized structures, suggesting that she has overgeneralized residual V2 across verb types and clause types. Emily, on the other hand, is very target-like in structures involving residual V2 in English, but also allows auxiliaries and dummy-do to move across the subject in topicalized structures, overgeneralizing residual V2 to apply to non-subject-initial declaratives. Finally, Sunniva, is very precocious and very target-like in all the relevant structures, which may be an indication of acceleration due to CLI from Norwegian V2. We discuss these results with reference to language balance, finding that the measures available to us suggest that the differences between the children cannot straightforwardly be explained by language dominance. Instead, we suggest that these results can be accounted for by ambiguity in the English system, leaving the data open to several possible interpretations when acquired in contact with the consistent V2 system in Norwegian. This has several consequences: (i) the three girls’ parsers interpret the input differently, (ii) differences between the three children are qualitative rather than quantitative, and (iii) there has to be some mechanism that ensures that the children can ‘recover’ from these non-target-like grammars. In this paper, we will focus on the first two issues. (shrink)

Although our concepts of “Mama,” “milk,” and “mice” have much in common, the suggestion that they are identical in structure in the mind of the prelinguistic child is mistaken. Even infants think about objects as different from substances and appreciate the distinction between kinds (e.g., mice) and individuals (e.g., Mama). Such cognitive capacities exist in other animals as well, and have important adaptive consequences.

This essay focuses on the structure of agency in Georg Ernst Stahl's model of organic order and the role that it plays for the difference between living and non-living beings in the discourses of medicine and natural history around 1700. Stahl calls the order of organic beings an "organism". He characterizes the "organism" through the notions of tonic movement, energy and ratio. The tonic movement is a mechanism of contraction and relaxation of organic units to direct fluids to certain parts (...) of the body; the energy represents a certain, limited potential of the living body to act spontaneously and to react if it is irritated; and the ratio expresses the logic of a processual, directed order imposed on corporeal dispositions. This ratio inheres in natural agents. However, to establish his theory of agency, Stahl first analyzes the irregular blood movements that characterize diseases. The capacity of the organic body to change these movements and to heal itself in redirecting them, leads him to the assumption that such bodies can regulate their own order and that self-regulation requires an autonomous agent.

When read as a theory that is supposed to mirror, represent or fit some collection of historical data, critics argue that Kuhn’s theory of paradigm shift in Structure of Scientific Revolutions fails by cherry-picking and underdetermination. When read as the ground for a socio-epistemological conception of rationality, critics argue that Kuhn’s theory fails by either the naturalistic fallacy or underarticulation. This paper suggests that we need not view Structure as a historian’s attempt to accurately depict scientific theory change or a (...) philosopher’s attempt to suggest, more normatively, the factors we ought to consider in theory choice. Instead, we might use Kuhn’s theory as a metaphilosophical frame through which to better understand the limits of otherwise intractable philosophical debates. We can focus on Kuhn’s theory not as a proposition or model to confirm, but as something we might use as a tool for understanding. Philosophers have discussed the justice and care orientations in ethics as two theories for which there will be some common, constraining set of intuitions to confirm one theory over the other, to demonstrate that protecting rights is fundamentally more valuable that fulfilling needs or that fulfilling needs is fundamentally more valuable that protecting rights. Instead of conceptualizing this conversation as a choice between two theories, this paper looks to Ian Hacking’s interpretation of Kuhn’s paradigm concept to suggest that working in the world of justice is very different than working in the world of care, as each orientation is a paradigm with its own cognitive and contextual standards of theory assessment. To start, after Larry Laudan, each has its own ontology, methodology, aims and values. But moreover, after Ian Hacking, each has an even larger, entrenched collection of projectible predicates. Though Carol Gilligan herself uses the metaphor of gestalt shift in a few places to characterize the move from the justice to the care perspective, the insight—that what many assume to be a standard exercise in theory choice is really more of a paradigm shift—has been under theorized by ethicists and ignored by philosophers of science. This paper brings the full resources of Structure and its secondary literature to this metaethical issue, while making the larger point that Structure has an important pragmatic role to play, when it comes to the understanding philosophical debates, even if we cannot secure the truth of Kuhn’s theory.

I will defend a purely structural account of the different readings arising from the German adverb wieder ÒagainÓ. We will be concerned with the so-called repetitive/restitutive ambiguity. The claim is that the ambiguity can be resolved entirely in terms of syntactic scope. The theory assumes a rather abstract syntax. In particular, abundant use is made of KratzerÕs (1994) voice phrase, which plays a central role for the derivation of repetitive readings. One of the leading ideas of the analysis is (...) that the structural accusative position has wide scope with respect to the agent relation expressed by the head of the voice phrase. If wieder precedes an accusative object, a repetitive reading is obligatory. If wieder follows the accusative object, two readings are available due to two possible positions of wieder. The analysis is an improvement of the proposal of Stechow (1995). It solves a number of questions left open there and considers a range of new data. (shrink)

Background Regardless of national contexts, the institutions responsible for research ethics, founded on international regulations, are all expected to be structured and to operate in a common way. Our experience with several countries on different continents, however, has raised questions in this regard. This article examines the differences and structural weaknesses of ethics committees in four countries where we have conducted the same socio-anthropological study in the field of reproductive health. Methods In addition to recording our observations during (...) field surveys for this study, we performed a documentary review and interviewed expert members of ethics committees, research participants, and researchers who had experience with requesting ethics approvals for research protocols in the field of social sciences and health. Results The results of this study showed that, despite having the same mandate, the committees functioned differently, while they all exhibited the same weaknesses. Thus, the universalization and standardization of institutional conditions for applying ethical standards in research still present problems that are, at the very least, relevant. Conclusion This study on ethics committees in four countries demonstrated the profound influence of context on the ways in which different institutions function and enforce regulations. In effect, in all social fields, every innovation is infused by its context. (shrink)

We examine the effective categoricity of equivalence structures via Ershov's difference hierarchy. We explore various kinds of categoricity available by distinguishing three different notions of isomorphism available in this hierarchy. We prove several results relating our notions of categoricity to computable equivalence relations: for example, we show that, for such relations, computable categoricity is equivalent to our notion of weak ω-c.e. categoricity, and that $\Delta _2^0 $ -categoricity is equivalent to our notion of graph-ω-c.e. categoricity.

This article argues that the second part of the Parmenides (137-166) consists not only of the well-known logical structure that has been widely studied but also of a great variety of definitions of forms. My aim is to show how these definitions depend on a specific group of closely connected primary forms (i.e., same, different, part, whole). The definitions that Parmenides provides help Socrates overcome his failure in attempting to define forms in the first part of the dialogue.

With the advent of big data, the use of network data to characterize travel has gradually become a trend. Tencent Migration big data can fully, dynamically, immediately, and visually record the trajectories of population migrations with location-based service technology. Here, the daily population flow data of 346 cities during the Spring Festival travel rush in China were combined with different travel modes to measure the spatial structure and spatial patterns of an intercity trip network of Chinese residents. These data were (...) then used for a comprehensive depiction of the complex relationships between the population flows of cities. The results showed that there were obvious differences in the characteristics of urban networks from the perspective of different modes of travel. The intercity flow of aviation trips showed a core-periphery structure with national hub cities as the core distribution. Trips by train showed a core-periphery structure with cities along the national railway artery as the core. This gradually decreased toward hinterland cities. Moreover, the intercity flow of highway trips indicated a spatial pattern of strong local aggregation that matched the population scale. (shrink)

This article investigates differences in structural tendencies between Japanese newspaper editorials and front-page columns. Although intuitively recognized by Japanese people, such differences have tended to be empirically overlooked in discourse or rhetoric research. This study compares the two text types, specifically focusing on the location of the main topic in the text item rather than the main thesis, the former of which has received less empirical attention than the latter in Japanese discourse research. The study analyzed 30 (...) editorials and 30 front-page columns from three major Japanese newspapers. The results show that the editorials have an early placement pattern, whereas the columns tend to have delayed introductions. These differences were statistically significant, empirically demonstrating how the intuitively recognized structural tendencies between the two text types crucially differ. The finding that there is a systematic early placement of the main topic in Japanese editorials is indicative of a basic common feature among languages in the editorial genre. From a methodological perspective, the study demonstrates the validity of the index of the main topic location as an analytical tool to distinguish different textual structures. (shrink)

This essay describes and evaluates the conception of mereological structure that underpins Deleuze’s account of ontogenesis in Difference and Repetition. A theory of mereology is a theory of composition: it asks what it is to be a part making a whole, what it is to be a whole collecting its parts; in short, in what the relation of making or composing consists. The locus classicus for modern mereology is the third of Husserl’s Logical Investigations (‘On the Theory of Wholes and (...) Parts’), which deduces the definitions, axioms and principles governing the relation of parthood and associated notions, such as wholeness, separation, simplicity and complexity. My question is this: what happens to these notions when they are no longer the terms of a ‘calculus of individuals’ and, instead, become the terms of a differential calculus of individuation?

In this paper, I examine some of the presuppositions that underpin the practice and interpretation of multi-person dialogue – that is, in contexts involving more than two interlocutors – with particular thought for the university seminar. I outline the ‘dialogical phenomenology’ of Beata Stawarska as useful on this count; however, I argue that Stawarska’s account is steeped in a philosophical ‘dyadic paradigm’ which has limiting consequences for practitioners of dialogue looking to understand the nature of dialogue in a group context. (...) Against this paradigm, I argue that there are many varieties of intersubjectivity that have not been widely discussed, including we-you, we-yous, I-yous and we-they intersubjective structures. I will look further at how an understanding of these structures is valuable for dialogue within educational praxes and for the Humanities more broadly. (shrink)

Understanding individual differences in cognitive performance is an important part of understanding how variations in underlying cognitive processes can result in variations in task performance. However, the exploration of individual differences in the components of the decision process—such as cognitive processing speed, response caution, and motor execution speed—in previous research has been limited. Here, we assess the heritability of the components of the decision process, with heritability having been a common aspect of individual differences research within other (...) areas of cognition. Importantly, a limitation of previous work on cognitive heritability is the underlying assumption that variability in response times solely reflects variability in the speed of cognitive processing. This assumption has been problematic in other domains, due to the confounding effects of caution and motor execution speed on observed response times. We extend a cognitive model of decision‐making to account for relatedness structure in a twin study paradigm. This approach can separately quantify different contributions to the heritability of response time. Using data from the Human Connectome Project, we find strong evidence for the heritability of response caution, and more ambiguous evidence for the heritability of cognitive processing speed and motor execution speed. Our study suggests that the assumption made in previous studies—that the heritability of cognitive ability is based on cognitive processing speed—may be incorrect. More generally, our methodology provides a useful avenue for future research in complex data that aims to analyze cognitive traits across different sources of related data, whether the relation is between people, tasks, experimental phases, or methods of measurement.

This was in direct contrast to the first forty years immediately following the recognition of graphic representations in Upper Paleolithic contexts.

The terms ‘structural injustice’ and ‘systemic injustice’ are commonly used, but their meanings are elusive. In this paper, I sketch an ontology of social systems that embeds accounts of social structures, relations, and practices. On this view, structures may be intrinsically problematic, or they may be problematic only insofar as they interact with other structures in the system to produce injustice. Because social practices that constitute structures set the backdrop for agency and identity, socially fluent agents reproduce the systems, (...) often unknowingly and unintentionally. The account aims to capture how agents both depend on and enact structures, and do so in ways that, as Ta-Nehisi Coates says, ‘land on the body’. (shrink)
