In this brief note I claim that, contrary to what Esfeld argues in his paper in this same volume, Kim's position with respect to the problem of causal exclusion does indeed commit him to the causal heterogeneity of realized properties.

Summary From the following discussion, we conclude that: (a) the homogeneity of space implies (in special relativity) the homogeneity of time, and vice versa; (b) the assumption of homogeneity of space (or time) implies that the transformation formulae must be linear (see Equations (10) and (17)).

Central to Wilfrid Sellars' philosophical system is his belief that science's current ontology is inadequate as it fails to provide for an acceptable account of perceptual experience. Unfortunately, this remains the most puzzling plank in his philosophy. Sellars himself argues for this position via his wellknown example of a pink ice cube and its homogeneous colour. This homogeneity, says Sellars, bars the acceptance of science's present ontology of achromatic particles, and requires the introduction of items which are truly coloured. (...) Only with such a revised and expanded ontology, with all that entails, can science adequately meet its explanatory demands. I aim here to remedy at least some of the confusions and misunderstandings this position has engendered. But I mean to take a different route from Sellars. In short, given the problems with Sellars' views on homogeneity, I will argue for the Sellarsian conclusion as to the inadequacy of present scientific ontologies, yet without reliance on the puzzling doctrine of homogeneity. I begin then with a detailed examination of Sellars official position, indicate the trouble spots, and begin an alternative route. As I conceive things, however, the position I will sketch is still thoroughly Sellarsian, for it proceeds from premises Sellars himself has endorsed. (shrink)

In an ongoing longitudinal study, which started in 1994, we are examining the moral development of business apprentices (sensu Kohlberg). The focal point of this project is a critical analysis of Kohlberg's thesis of homogeneity, according to which people should judge every moral issue from the point of view of their "modal" stage (i.e. the most frequently used stage of moral reasoning) regardless of any situation-specificity. Empirical data-even Kohlberg's own-however, show that an individual's judgements are usually spread around her/his (...) modal stage. This is not necessarily due to measurement error but may also be interpreted as a situation-specific variation which could be described by the hypothesis of "moral segmentation". In this article we present results on the status of moral development of apprentices in the business context (within different types of situations). Contrary to Kohlberg's theory, our results seem to support the hypothesis of segmentation. The data reflect a great amount of intra-individual variation unaccounted for by the concept of "structured wholeness". (shrink)

Wesley Salmon has recently proposed a new theory of scientific explanation based on a model which he calls the statistical-relevance model. It is intended primarily as an account of the structure of explanations of particular events--explanations which, according to Salmon, are very often motivated largely by practical concerns. Two important features of this account are the concepts of homogeneity and screening off. In this paper we argue that the employment of these two concepts (which, in fact, are intimately connected) (...) is fundamentally at odds with the desire to capture everyday explanations of the practical sort, and that it leads instead to an account in which the only satisfactory explanations are those expressed in the very deepest physical terms.

The faithfulness condition (FC) is a useful principle for inferring causal structure from statistical data. The usual motivation for the FC appeals to theorems showing that exceptions to it have probability zero, provided that some apparently reasonable assumptions obtain. However, some have objected that, the theorems notwithstanding, exceptions to the FC are probable in commonly occurring circumstances. I argue that exceptions to the FC are probable in the circumstances specified by this objection only given the presence of a condition that (...) I label homogeneity, and furthermore that this condition typically does not obtain in the FC’s intended domain of application. (shrink)

This article traces the semantics of ?life? and ?vitality? in Carl Schmitt up to the 1930s. It shows that Schmitt deploys these vitalist elements against the modern ?spirit of technicity? in his attempt to combat the lack of substantial ideas in modern politics. However, Schmitt himself cannot escape a fundamental political relativism. There remains an unstable tension at the heart of his thought between the quest for substance and the quest for order. The latter is relativist because it is a (...) quest for order as such, any order. Although Schmitt's semantics of life and vitality is not drawn from a biological register, it adopted a völkisch meaning in 1933. Anti-Semitism becomes a form of life and racial homogeneity fills in for substance. The article concludes that, while there are good reasons for criticizing the modern ?spirit of technicity,? Schmitt's critical model is fundamentally flawed. (shrink)

My article aims to develop a relational, pluralistic political theory that moves beyond standard theories of liberal democracy, and to consider how such a theory translates into our public school settings. I use a narrative style argument to share stories that focus on homogeneity and diversity from my visit to a Japanese elementary school, as I consider, drawing on the work of Chantal Mouffe, the important role harmony and disagreement, and a tension between homogeneity and diversity, play in (...) encouraging citizens to contribute to their school and their larger communities in a democracy-always-in-the-making. I argue that there is much we can learn from Japanese educational practices. (shrink)

This paper discusses issues to do with the empirical basis of modern economics and points towards the need to look more closely at the ?homogeneity assumption? that underpins much economic theory. It argues that severe problems currently prevent economics from becoming more persuasive to both students of economics and those outside the discipline. The issue involves the management of disciplinary boundaries, and excessive use of the ?homogeneity assumption.? Three areas of concern are explored. First is the literature on (...) causes of growth, and the role of policy. The paper documents reasons to doubt the existence of robust relationships between growth and policy variables. Second is the ?homogeneity assumption? that different countries are usefully viewed as members of a single population. Third is evidence suggesting that an assumption of ?normal? maximizing behaviour has to be justified, not just assumed, and that regular deviations from the usual maximizing assumptions occur with gender and culture. The paper argues that a central issue in economic methodology and pedagogy should be, as North implicitly argues, the negotiation of disciplinary boundaries: what economics can versus cannot explain. It suggests more explicitly basing the choice of explanatory models on empirics identifying where the model applies. (shrink)

In his recent book Scientific Explanation and the Causal Structure of the World Wesley Salmon provides a detailed explanation of objective homogeneity, a concept which is central to his S-R model of explanation. 1 propose a modification of Salmon's definition which both simplifies and (in minor ways) corrects it, while at the same time generalizes it by including an important temporal factor that is missing from the original. I argue that if the world is irreducibly stochastic, then objective probabilities (...) (determined by objective homogeneous reference classes) must be temporally relativized. We can speak coherently of the objective probability of a particular event relative to a given point in time, but not of the objective probability of the event simpliciter. I briefly explore the consequences, of the temporal relativity of objective homogeneity for Salmon's attempt to secure an objective (nonepistemic, nonpraagmatic) S-R basis for causal explanation.

In a three-candidate election, a scoring rule s (s in [0,1]) assigns 1, s, and 0 points (respectively) to each first, second and third place in the individual preference rankings. The Condorcet efficiency of a scoring rule is defined as the conditional probability that this rule selects the winner in accordance with Condorcet criteria (three Condorcet criteria are considered in the paper). We are interested in the following question: What rule s has the greatest Condorcet efficiency? After recalling the known (...) answer to this question, we investigate the impact of social homogeneity on the optimal value of ?. One of the most salient results we obtain is that the optimality of the Borda rule (s=1/2) holds only if the voters act in an independent way. (shrink)

We consider the question of when, given a subset A of M, the setwise stabilizer of the group of automorphisms induces a closed subgroup on Sym(A). We define s-homogeneity to be the analogue of homogeneity relative to strong embeddings and show that any subset of a countable, s-homogeneous, ω-stable structure induces a closed subgroup and contrast this with a number of negative results. We also show that for ω-stable structures s-homogeneity is preserved under naming countably many constants, (...) but under slightly weaker conditions it can be lost by naming a single point.

When analyzing database query languages a roperty, of theories, the pseudo-finite homogeneity property, has been introduced and applied (cf. [3]). We show that a stable theory has the pseudo-finite homogeneity property just in case its expressive power for finite states is bounded. Moreover, we introduce the corresponding pseudo-finite saturation property and show that a theory fails to have the finite cover property if and only if it has the pseudo-finite saturation property.

The Condorcet efficiency of a social choice procedure is usually defined as the probability that this procedure coincides with the majority winner (or majority ordering) in random samples, given a majority winner exists (or given the majority ordering is transitive). Consequently, it is in effect a conditional probability that two sample statistics coincide, given certain side conditions. We raise a different issue of Condorcet efficiencies: What is the probability that a social choice procedure applied to a sample matches with the (...) majority preferences of the population from which the sample was drawn? We investigate the canonical case where the sample statistic is itself also majority rule and the samples are drawn from real world distributions gathered from national election surveys in Germany, France, and the United States. We relate the results to the existing literature on majority cycles and social homogeneity. We find that these samples rarely display majority cycles, whereas the probability that a sample misrepresents the majority preferences of the underlying population varies dramatically and always exceeds the probability that the sample displays cyclic majority preferences. Social homogeneity plays a fundamental role in the type of Condorcet efficiency investigated here. (shrink)

The aim of this paper is to show that biological kinds can be causally homogeneous, although all biological causes are identical with configurations of physical causes. The paper considers two different strategies to establish that result: the first one relies on two different manners of classification (according to function and according to composition); the other one exploits the idea of biological classifications being rather coarse-grained, whereas physical classifications are fine-grained.

This article examines the relationship between the classical Marxist tradition and the conceptual roots of totalitarianism. Here totalitarianism is understood to entail the attempt to frame the developmental impulses of modernity within the logic of a premodern political imaginary—defined as internally homogenous and transparent to itself. In the first part, we take issue with those who try to distinguish between the thought of Marx and Engels, and who insist that it is only in Engels's thought that the traces of a (...) totalitarian politics might be found. In the second section, we outline briefly the context within which Marx's thought was developed, after which we argue that Marx's vision of communism is dependent on the three-phase vision of historical process which he inherited from Hegel. Without denying the historical peculiarities of the imposition of communism in Russia, we conclude that it is out of this latter vision of history that the conceptual roots of totalitarianism must be located.

We study the expansion of stable structures by adding predicates for arbitrary subsets. Generalizing work of Poizat-Bouscaren on the one hand and Baldwin-Benedikt-Casanovas-Ziegler on the other we provide a sufficient condition (Theorem 4.7) for such an expansion to be stable. This generalization weakens the original definitions in two ways: dealing with arbitrary subsets rather than just submodels and removing the 'small' or 'belles paires' hypothesis. We use this generalization to characterize in terms of pairs, the 'triviality' of the geometry on (...) a strongly minimal set (Theorem 2.5). Call a set A benign if any type over A in the expanded language is determined by its restriction to the base language. We characterize the notion of benign as a kind of local homogenity (Theorem 1.7). Answering a question of [8] we characterize the property that M has the finite cover property over A (Theorem 3.9).

Throughout his metaphysical writings, Sellars maintains that current microtheory, with its particulate paradigm, can never depict adequately---even in principle---a universe populated with sentient beings like us. Why not? Experience for us involves the presence of an occurrent perceptual core of ultimately homogeneous secondary qualities. Sellars’ “Grain Argument” demonstrates (1) that physical objects qua clouds of discrete particles cannot instantiate such qualities and (2) that they cannot be assigned to an intrasentient realm construed as clusters of discrete, particulate neurons. Neither, contends (...) Sellars, can they simply be eliminated from the inventory of any theory claiming to be both empirical and conceptually independent of common sense. And since common sense fails to provide an adequate picture of reality, our only course is to abandon the particulate paradigm of current microtheory in favor of a process paradigm. This paper traces and develops, in dialog form, these arguments. (shrink)

The aim of this paper is to defend the causal homogeneity of functional, mental properties against Kim’s attack. It is argued that (a) token identity is sufficient for mental causation, that (b) token identity implies a sort of functional reduction, but that (c) nonetheless functional, mental properties can be causally homogeneous despite being multiply realizable: multiple composition is sufficient for multiple realizability, but multiple composition does not prevent the realizers from having their pertinent effects in common. Thus, the causal (...) exclusion problem provides no argument for abandoning the position that there are functional, mental properties that are natural kind properties. (shrink)

If one examines the sky at sunset on a clear night, one seems to see a continuum of colors from reds, oranges and yellows to a deep blue-black. Between any two colored points in the sky there seem to be other colored points. Furthermore, the changes in color across the sky appear to be continuous. Although the colors at the zenith and the horizon are obviously distinct, nowhere in the sky can one see any color borders, and every sufficiently small (...) region of the sky is made up of regions that all seem to be of the same color.

A study encompassing a number of UK Universities identified a widespread implicit environmental determinism employed in the teaching of Economics to business studies undergraduates. In this paper the author argues that this bias is an inevitable by-product of the methodological individualism adopted within mainstream economics. The author concludes that methodological individualism is, therefore, flawed both as a mechanism for accessing the reality of the business world and the power of firms within it, and for teaching others about that reality, particularly (...) as it also acts to undermine student motivation.

Distinguishing explicit from implicit knowledge on the basis of the active representation of certain propositional attitudes fails to provide an explanation for dissociations in learning performance under implicit and explicit conditions. This suggests an account of implicit and explicit knowledge grounded in the presence of multiple learning mechanisms, and multiple brain systems more generally. A rough outline of a connectionist account of this kind is provided.

The usual construction of models of NFU (New Foundations with urelements, introduced by Jensen) is due to Maurice Boffa. A Boffa model is obtained from a model of (a fragment of) Zermelo–Fraenkel with Choice (ZFC) with an automorphism which moves a rank: the domain of the Boffa model is a rank that is moved. “Most” elements of the domain of the Boffa model are urelements in terms of the interpreted NFU. The main result of this paper is that the restriction (...) of the membership relation of the original model of set theory with automorphism to the domain of the Boffa model is first-order definable in the language of NFU. In particular, all information about the extensions in the original model of the urelements of the model of NFU is definable in terms of NFU. A corollary (answering a question of Thomas Forster) is that the urelements in a Boffa model are not homogeneous. (shrink)

is the thesis that everything supervenes upon the spatiotemporal distribution of local intrinsic qualities. A recent threat to HS, originating in thought experiments by Armstrong and Kripke, claims that the mere possibility of rotating homogeneous discs proves HS false. I argue that the rotating disc argument (RDA) fails. If I am right, Humeans needn't abandon or alter HS to make sense of rotating homogeneous discs. Homogeneous discs, as necessarily understood by RDA, are not the sorts of things in which we (...) should believe. These discs do not belong in our ontology - not because there is a problem with their homogeneity, but (surprisingly) because there is a problem with their rotation. RDA is shown to be a kind of parody of classic arguments for spatial substantivalism. (shrink)

Some recent philosophical debate about persistence has focussed on an argument against perdurantism that discusses rotating perfectly homogeneous discs (the `rotating discs argument'; RDA). The argument has been mostly discussed by metaphysicians, though it appeals to ideas from classical mechanics, especially about rotation. In contrast, I assess the RDA from the perspective of the philosophy of physics. After introducing the argument and emphasizing the relevance of physics (Sections 1 to 3), I review some metaphysicians' replies to the argument, especially (...) those by Callender, Lewis, Robinson and Sider (Section 4). Thereafter, I argue for three main conclusions. They all arise from the fact, emphasized in Section 2, that classical mechanics (non-relativistic as well as relativistic) is both more subtle, and more problematic, than philosophers generally realize. The first conclusion is that the RDA can be formulated more strongly than is usually recognized: it is not necessary to ``imagine away'' the dynamical effects of rotation (Section 5.5). The second is that in general relativity, the RDA fails because of frame-dragging (Section 5.6). The third is that even setting aside general relativity, the strong formulation of the RDA can after all be defeated (Section 6 onwards). Namely, by the perdurantist taking objects in classical mechanics (whether point-particles or continuous bodies) to have only temporally extended, i.e. non-instantaneous, temporal parts: which immediately blocks the RDA. Admittedly, this version of perdurantism defines persistence in a weaker sense of `definition' than pointilliste versions that aim to define persistence assuming only instantaneous temporal parts. But I argue that temporally extended temporal parts: (i) can do the jobs within the endurantism-perdurantism debate that the perdurantist wants temporal parts to do; and (ii) are supported by both classical and quantum mechanics. (shrink)

I give reasons to suggest that the various 'homogeneous substance' objections to perdurance theory should not be regarded as raising serious difficulties. The main strategy is to show that there are equally exotic possibilities involving extended mereological simples that may turn the tables on the endurance theorist, insofar as she will have difficulties with these cases analogous to those she raises for the perdurantist. I conclude that such exotic cases are less useful that we might suppose in adjudicating between these (...) competing doctrines of persistence. (shrink)

Given a finite relational language L is there an algorithm that, given two finite sets A and B of structures in the language, determines how many homogeneous L structures there are omitting every structure in B and embedding every structure in A? For directed graphs this question reduces to: Is there an algorithm that, given a finite set of tournaments Γ, determines whether QΓ, the class of finite tournaments omitting every tournament in Γ, is well-quasi-order? First, we give a nonconstructive (...) proof of the existence of an algorithm for the case in which Γ consists of one tournament. Then we determine explicitly the set of tournaments each of which does not have an antichain omitting it. Two antichains are exhibited and a summary is given of two structure theorems which allow the application of Kruskal's Tree Theorem. Detailed proofs of these structure theorems will be given elsewhere. The case in which Γ consists of two tournaments is also discussed. (shrink)

In this article Elias Hemelsoet questions the way irregular migrants are approached in educational policymaking. In most cases, estimations of the number of irregular migrants serve—despite large methodological problems—as a starting point for policymaking. Given the very diverse composition of this group of people, the question is whether residence status is an appropriate benchmark for dealing with the social problems related to these people. There seems to be a homogenizing tendency at work that reduces the complexity of irregular migration. Preferable (...) distinctions are overlooked or even denied. Inclusive education seems to provide an alternative that does not reduce individuals to a group they belong to, claiming that differences only matter at the individual level. The question is whether such an approach entails a new form of homogenization. Using the case of Roma people, Hemelsoet argues here that group differences do matter for educational practice, theory, and policy. Qualitative data on the social practices of groups can help provide insight into the particularity of situations. This “insight” or “understanding,” in its turn, is a requirement in order for policymakers to make well-considered choices. (shrink)

We prove a main gap theorem for locally saturated submodels of a homogeneous structure. We also study the number of locally saturated models, which are not elementarily embeddable into each other.

Studies on the development of cell populations are often based on results of the theory of stochastic birth- and death-processes (continuous or discrete (seee.g. references inVogel, Niewisch &Matioli (1969), in some cases, death may be interpreted not as actual death of the cell bute.g. as a recruitment of the cell considered into another cell compartment, etc.). It is usually assumed that the conditions for the development are homogeneous,i.e. that the probabilities of births and deaths are independent on the time. However, (...) in most situations, this assumption is not fulfilled (owing to the maturation and differentiation of cells, changes of the microenvironment, inducing factors, etc.). Then it is necessary to study the development of cell populations under non-homogeneous conditions. In this paper, some properties of appropriate birth- and death-processes under nonhomogeneous conditions are studied; formulae given in section 4 permit calculation of some characteristics describing the cell population size distribution at individual discrete epochs (at individual generations) during the development of the cell population considered.

We generalize tools and results from first order stable theories to groups inside a simple stable strongly homogeneous model.

We analyze the two cardinal properties of definable sets in homogeneous graphs.

We study the class of elementary submodels of a large superstable homogeneous model. We introduce a rank which is bounded in the superstable case, and use it to define a dependence relation which shares many (but not all) of the properties of forking in the first order case. The main difference is that we do not have extension over all sets. We also present an example of Shelah showing that extension over all sets may not hold for any dependence relation (...) for superstable homogeneous models. (shrink)

A Dedekind algebra is an order pair (B, h) where B is a non-empty set and h is a similarity transformation on B. Each Dedekind algebra can be decomposed into a family of disjoint, countable subalgebras called the configurations of the algebra. There are 0 isomorphism types of configurations. Each Dedekind algebra is associated with a cardinal-valued function on called its configuration signature. The configuration signature counts the number of configurations in each isomorphism type which occur in the decomposition of (...) the algebra. Two Dedekind algebras are isomorphic iff their configuration signatures are identical. It is shown that configuration signatures can be used to characterize the homogeneous, universal and homogeneous-universal Dedekind algebras. This characterization is used to prove various results about these subclasses of Dedekind algebras. (shrink)

It is well known that interval orders are particularly interesting in decision theory, since they are reflexive, complete and nontransitive binary relations which may be fully represented by means of two real-valued functions. In this paper, we discuss the existence of a pair of nonnegative, positively homogeneous and semicontinuous real-valued functionals representing an interval order on a real cone in a topological vector space. We recover as a particular case a result concerning the existence of a nonnegative, positively homogeneous and (...) continuous utility functional for a complete preorder on a real cone in a topological vector space.

We give a detailed account of the Algebraically Closed and Existentially Closed members of the second Lee class B 2 of distributive p-algebras, culminating in an explicit construction of the countable homogeneous universal model of B 2. The axioms of Schmid [7], [8] for the AC and EC members of B 2 are reduced to what we prove to be an irredundant set of axioms. The central tools used in this study are the strong duality of Clark and Davey [3] (...) for B 2 and the method of Clark [2] for constructing AC and EC algebras using a strong duality. Applied to B 2, this method transfers the entire discussion into an equivalent dual category X 2 of Boolean spaces which carry a pair of tightly interacting orderings. The doubly ordered spaces of X 2 prove to be much more readily constructed and analyzed than the corresponding algebras in B 2. (shrink)

The paper aims to establish if Grassmann’s notion of an extensive form involved an epistemological change in the understanding of geometry and of mathematical knowledge. Firstly, it will examine if an ontological shift in geometry is determined by the vectorial representation of extended magnitudes. Giving up homogeneity, and considering geometry as an application of extension theory, Grassmann developed a different notion of a geometrical object, based on abstract constraints concerning the construction of forms rather than on the homogeneity (...) conditions required by the modern version of the theory of proportions. Secondly, Grassmann’s conception of mathematical knowledge will be investigated. Parting from the traditional definition of mathematics as a science of magnitudes, Grassmann considered mathematical forms as particulars rather than universals: the classification of the branches of mathematics was thus based on different operational rules, rather than on empirical criteria of abstraction or on the distinction of different species belonging to a common genus. It will be argued that a different notion of generalization is thus involved, and that the knowledge of mathematical forms relies on the understanding of the rules of generation of the forms themselves. Finally, the paper will analyse if Grassmann’s approach in the first edition of the Ausdehnungslehre should be explained in terms of the notion of purity of method, and if it clashes with Grassmann’s later conventionalism. Although in the second edition the features of the operations are chosen by convention, as it is the case for the anti-commutative property of the multiplication, the choice is oriented by our understanding of the resulting forms: a simplification in the algebraic calculus need not correspond to a simplification in the ‘dimensional’ interpretation of the result of the multiplicative operation.

Species concepts for bacteria and other microbes are contentious, because they are often asexual. There is a Problem of Homogeneity: every mutation in an asexual lineage forms a new strain, of which all descendents are clones until a new mutation occurs. We should expect that asexual organisms would form a smear or continuum. What causes the internal homogeneity of asexual lineages, if they are in fact homogeneous? Is there a natural “species concept” for “microbes”? Two main concepts devised (...) for metazoans and metaphytes have been applied to bacteria. One is the Recombination Concept, a revised form of the Biological Species Concept in which the homogenizing mechanism is the sharing of genome fragments, somewhat akin to sexual recombination. The other is the Ecological Species Concept, in which the ecological niche is that which maintains lineages as cohesive. In this paper I will discuss these two concepts, and offer an underlying model that conjoins them, and consider the implications for species concepts in general. In short, my argument is that asexual species are instances of the most primitive and underived notion of species, which I will call “quasispecies”, following Eigen, and that sexual species are merely one derived kind of species. Moreover, I will argue that there is a continuum of recombination from simple viral models in which each strain is a clone, through to obligate recombination of 50% of the parents’ genome, and that consequently there is no sharp division between “microbial” and more familiar species.

In one of his last texts, Foucault defined his philosophical enterprise as an “analysis of the conditions in which certain relations between subject and object are formed or modified, insofar as they are constitutive of a possible knowledge”1, or again as “the manner in which the emergence of games of truth constituted, for a particular time and place and certain individuals, the historical a priori of a possible experience”2. Despite its eclipse during the genealogical period, the notion of the historical (...) a priori is thus reaffirmed as central by later Foucault. There is, however, an essential modification with respect to its archaeological problematisation: in The Order of Things, the various historical a priori were characterized by a specific relation between being and language, a relation in which the subject of knowledge did not always nor necessarily have a place. The Renaissance episteme was defined by the homogeneity of words and things, and its Classical counterpart, by the transparent distance between being and representation, which excluded any positioning for the subject (the “place of the king”). Thus within the archaeological configuration, only the contemporary historical a priori was characterized by the invention of a new position for the subject of knowledge, that of Man, which generated the Analytic of Finitude and ultimately resulted in the “anthropological sleep” criticised at the end of The Order of Things. So although later Foucault re-focuses his work around the notion of the historical a priori, he gives the notion a considerable twist whereby the conditions of truth saying are no longer referred back to an implicit connection between being and language, but to the various relations historically established between “modes of subjectivation”3 and “modes of objectification”4. Correspondingly, these relations are not to be analysed from discourse, as in archaeology, nor from the constituting structures of subjectivity, as in phenomenology, but genealogically, i.e..

This paper considers the questions that Badiou's theory poses to the culture of economic managerialism within education. His argument that radical change is possible, for people and the situations they inhabit, provides a stark challenge to the stifling nature of much current educational debate. In Saint Paul: The Foundation of Universalism , Badiou describes the current universalism of capitalism, monetary homogeneity and the rule of the count. Badiou argues that the politics of identity are all too easily subsumed by (...) the prerogatives of the marketplace and unable to present, therefore, a critique of the status quo. These processes are, he argues, without the potential for truth. What are the implications of Badiou's claim that education is the arranging of 'the forms of knowledge in such a way that truth may come to pierce a hole in them' ( Badiou, 2005 , p. 9)? I will argue that Badiou's theory opens up space for a kind of thinking about education that resists its colonisation by the cultures of management and marketisation and leads educationalists to consider the emancipatory potential of education in a refreshing new light.

In order to resolve problems about the normative aspects of representation without having to (1) provide a naturalized theory of intentional/semantic properties, (2) accept non-natural intentional/semantic properties into our worldview, or (3) eliminate intentionality, this article questions a basic assumption about the metaphysics of representation: that representation involves representation-objects. An alternative, nonreifying approach to the metaphysics of representation is introduced and developed in detail. The argumentative strategy is as follows. First, an adverbial view of linguistic representation is introduced. Two potential (...) objections are identified and considered. To respond to these objections, relationships between physical form and linguistic/representational form are examined. In the process, two ways of idealizing away from the heterogeneous details of actual language use are introduced: idealization toward homogeneity and idealization toward complete heterogeneity. I argue that an adverbial view of linguistic representation both allows for and requires that we idealize toward complete heterogeneity and that doing so has important implications for (1) our understanding of the relationship between physical form and representational form and (2) property attribution in general. These implications provide further indirect support for the alternative metaphysics of representation developed here. (shrink)

Given its contribution to enhancing the inclusiveness, responsiveness, transparency and accountability of socio-political decision-making, the deliberative model has achieved considerable prominence in recent times as a basis for revitalizing democracy. But notwithstanding its strengths, it has also become clear that the deliberative proposal exhibits certain weaknesses that stand in need of correction if it is to realize its potential for revitalizing democracy in our contemporary pluralistic and multicultural world. Not surprisingly, then, there have been calls for significant modifications to the (...) core proposal. Of particular interest for present purposes is Iris Marion Young’s call for a ‘communicative’ reappropriation of the standard model with a view to rendering it more inclusive of and responsive to difference. While Young’s call for reconfiguring the deliberative template in a manner conducive to treating difference as a resource rather than as a barrier to unity is judicious and timely, the present article contends that her communicative proposal does not go far enough to achieve the envisaged outcomes. Instead, to enhance inclusiveness and responsiveness to difference in a manner conducive to promoting mutual understanding and potentially transformative learning, a thoroughgoing dialogical reappropriation is called for, along the lines defended here. Only in this way can the deliberative proposal live up to its pluralistic as well as inclusive intent. Moreover, far from being an external imposition, a dialogical reconfiguration of the requisite sort is rather a means of liberating potentials inherent in the deliberative proposal from the outset but typically suppressed by an undue emphasis on homogeneity, uniformity and consensus.

Evidence-based psychiatry (EBP) has arisen through the application of evidence-based medicine (EBM) to psychiatry. However, there may be aspects of psychiatric disorders and treatments that do not conform well to the assumptions of EBM. This paper reviews the ongoing debate about evidence-based psychiatry and investigates the applicability, to psychiatry, of two basic methodological features of EBM: prognostic homogeneity of clinical trial groups and quantification of trial outcomes. This paper argues that EBM may not be the best way to pursue (...) psychiatric knowledge given the particular features of psychiatric disorders and their treatments. As a result, psychiatry may have to develop its own standards for rigour and validity. This paper concludes that EBM has had a powerful influence on how psychiatry investigates and understands mental disorders. Psychiatry could influence EBM in return, reshaping it in ways that are more clinically useful and congruent with patients’ needs. (shrink)

The contemporary confluence of globalization and ethical pluralism is at the origin of many ethical challenges that confront business nowadays, both in practice and in theory. One of the challenges arising from the development of globalization has to do with respect for cultural diversity. It is often said that the success of economic globalization tends towards social and cultural homogeneity. To the extent that cultural diversity is usually seen as a valuable reality, that global trend seems to contradict our (...) efforts to respect ethical pluralism, both personal and cultural, within society. In this paper I argue that (a) ethical minimalism, despite its emphasis on tolerance and justice, does not take pluralism seriously into account in present-day society, and (b) ethical minimalism is not suited to balancing the homogenizing trend of globalization. Certainly ethical norms are necessary, but by no means are they sufficient in themselves to encourage either justice or tolerance; nor are they sufficient to inspire and encourage good practices and sound regulations. Instead, virtue-based ethics has the capacity of inspiring and encouraging good practices. Particularly, virtue-based ethics is able to inspire a serious dialogue about ethical and legal issues both in the public arena and within organizations. (shrink)

Literature on place makes use of concepts like authenticity and is often structured around a critique of homogeneity or placelessness. This critique is reinforced by the discourse of conservation biology with its emphasis on protecting biodiversity and condemning some non-native species. However, a common emotional response of humans, when they are displaced, is to make where they are like where they felt at home. The debate around invasive species needs careful handling for both ecological and social reasons. This paper (...) addresses a gap in that debate by taking account of the emotional involvement of humans with plants and their caring for the immediate environment through the activity of gardening.

This article examines the Kantian thesis of the a priori nature of our knowledge of space. Because it makes the representation of objects possible as external to us and all others, and consequently, as distinct and individualized, space (whatever its structure may be) claims the status as necessary condition and as apriori possibility of all knowledge. However, in the light of various physical, psychological and philosophical considerations, it seems that the particular structure allocated by Kant to space (i.e. uniqueness, infinity, (...) continuity, homogeneity, isotropy, Euclidean character and three-dimensional character) is neither necessary nor a priori but is rather contingent and dependent on experience. For this reason a pragmatist relativization of the transcendental approach appears to be necessary: the structure of space which makes knowledge possible is not apriori in an absolute sense, but rather, it is determined within the context of a certain practice, which is characterized by a certain mode of interaction with the environment and reveals particular empirical constraints to which this spatial structure must fit.

McGinn claims that (1) there is nothing “inherently mysterious” about consciousness, even though (2) we will never be able to understand it. The first claim is no more than a rhetorical flourish. The second may be read either as a claim (1) that we are unable to construct an explanatory theory of consciousness, or (2) that any such theory must strike us as unintelligible, in the sense in which quantum mechanics is sometimes said to be unintelligible. On the first reading, (...) McGinn's argument is based on a false premiss (the “homogeneity constraint"). On the second reading, it suffers from the shortcoming that the central notion of intelligibility is too obscure to permit any definite conclusion. I close with a brief discussion of the contemporary tendency to reject non-physicalist approaches to consciousness on a priori grounds. (shrink)

Many historians of the calculus deny significant continuity between infinitesimal calculus of the seventeenth century and twentieth century developments such as Robinson’s theory. Robinson’s hyperreals, while providing a consistent theory of infinitesimals, require the resources of modern logic; thus many commentators are comfortable denying a historical continuity. A notable exception is Robinson himself, whose identification with the Leibnizian tradition inspired Lakatos, Laugwitz, and others to consider the history of the infinitesimal in a more favorable light. Inspite of his Leibnizian sympathies, (...) Robinson regards Berkeley’s criticisms of the infinitesimal calculus as aptly demonstrating the inconsistency of reasoning with historical infinitesimal magnitudes. We argue that Robinson, among others, overestimates the force of Berkeley’s criticisms, by underestimating the mathematical and philosophical resources available to Leibniz. Leibniz’s infinitesimals are fictions, not logical fictions, as Ishiguro proposed, but rather pure fictions, like imaginaries, which are not eliminable by some syncategorematic paraphrase. We argue that Leibniz’s defense of infinitesimals is more firmly grounded than Berkeley’s criticism thereof. We show, moreover, that Leibniz’s system for differential calculus was free of logical fallacies. Our argument strengthens the conception of modern infinitesimals as a development of Leibniz’s strategy of relating inassignable to assignable quantities by means of his transcendental law of homogeneity.

Wesley Salmon has advanced a new model of explanations of particular facts which requires that the explanans contain laws. The laws used in explanations (according to this model) are of the form P(A· C1,B)=p1... P(A· Cn,B)=pn. A condition imposed by Salmon on these laws is that the reference classes, i.e. A· C1... A· Cn, be homogenous with reference to the property B. A reference class A is homogenous with reference to a property B if every property which determines a place (...) selection with reference to B within A is statistically irrelevant to B in A. It is argued here that the concept of homogeneity cannot in general be satisfied in scientific explanations and that even a weaker requirement, "epistemic homogeneity," may be too strong. (shrink)

: A pronatalist perspective on maternal bodies renders the adoptive maternal body queer. In this essay, I argue that the queerness of the adoptive maternal body makes it a useful epistemic standpoint from which to critique dominant views of mothering. In particular, exploring motherhood through the lens of adoption reveals the discursive mediation and social regulation of all maternal bodies, as well as the normalizing assumptions of heteronormativity, "reprosexuality," and family homogeneity that frame a traditional view of the biological (...) family. As participants in motherhood who resist "repro-narrativity," " reprosexuality," and essentialism, adoptive maternal bodies have the potential to both queer our notions of normal mothering and normalize our notions of queer mothering.

The article 'Nominal Aspect' in Journal of Semantics (1991) is now outdated. For a more recent account of nominal aspect marking and Seinsart, see, for example: - Rijkhoff, Jan. 2010.

Just as languages can make different choices as to the way they represent verbal properties in the temporal dimension (Aktionsart, verbal aspect), languages can also make different choices as to the way they represent nominal properties in the spatial dimension (Seinsart, nominal aspect). For instance, we can refer to the same thing as: '50 grapes' (as when they are going to be distributed individually), 'a pound of grapes', or 'a bunch of grapes'. In other words, in the act of referring different spatial features of the property "grapeness" can be emphasized. It can be referred to as a number of distinct individual objects, as a mass, or as a collective entity (cf. Adams 1989: 3)." -/- NOMINAL ASPECT (Rijkhoff 2002/2004: 101): "We can define the notion "aspect" as the way in which a property or relation designated by a predicate is represented in some dimension. Depending on the type of predicate involved, two kinds of aspect can be distinguished: verbal and nominal aspect. Verbal aspect is concerned with representations in the temporal dimension, and nominal aspect with representations in the spatial dimension. The study of verbal aspect has a long tradition, but nominal aspect has only been introduced recently, at least in the sense in which it is used here. I have already mentioned the difference between covert and overt ways of marking aspectual distinctions (cf. section 2.6 on Aktionsart vs. verbal aspect marking and Seinsart vs. nominal aspect marking). In this chapter we will only be concerned with overt, inflectional expressions of nominal aspect." . (shrink)

The investigation of probabilistic causality has been plagued by a variety of misconceptions and misunderstandings. One has been the thought that the aim of the probabilistic account of causality is the reduction of causal claims to probabilistic claims. Nancy Cartwright (1979) has clearly rebutted that idea. Another ill-conceived idea continues to haunt the debate, namely the idea that contextual unanimity can do the work of objective homogeneity. It cannot. We argue that only objective homogeneity in combination with a (...) causal interpretation of Bayesian networks can provide the desired criterion of probabilistic causality. (shrink)

The only commonality between the various psychiatric disorders is that they reflect contemporary problematic behaviors. Some psychiatric disorders have a substantial genetic component, whereas others are essentially shaped by prevailing environmental factors. Because psychiatric ailments are so heterogeneous, any universal explanation of mental illness is not likely to have any clinical or theoretical utility. (Published Online November 9 2006).

Carl G. Hempel's doctrine of essential epistemic relativization of inductive-statistical explanation seems to entail the unintelligibility of the notion of objective homogeneity of reference classes. This discussion note explores the question of whether, as a consequence, essential epistemic relativization also entails the unintelligibility of the doctrine of indeterminism.

Whitehead was critical with respect to Poincaré’s conventionalism. However, Whitehead stood closer to Poincaré than Bertrand Russell when Russellinvoked Poincaré’s conventionalism to highlight that the choice between Arthur Eddington’s orthodox interpretation of Einstein’s general theory of relativity on the one hand, and Whitehead’s alternative interpretation on the other, is not a matter of empirical fact, but a matter of convention. Whitehead shared two of the premises of Poincaré’s conventionalism: the physics-independence of geometry, and the choice of a physical geometry amongst (...) geometries of constant curvature. This contributed significantly to his philosophical critique of Einstein, who held that the geometry of space-time depends on the physical distribution of matter, and that the non-homogeneity of this distribution (e.g., at the scale of the solar system) implies that the appropriate physical geometry is variably curved. Russell’s conventionalism, contrary to Whitehead’s view, did not take Poincaré’s premises into account, was shared by the logical positivists, and led to a philosophical defense of Einstein.

The homogeneity of time (i.e. the fact that there are no privileged moments) underlies a fundamental symmetry relating to the energy conservation law. On the other hand the obvious asymmetry between past and future, expressed by the metaphor of the arrow of time or flow of time accounts for the irreversibility of what happens. One takes this for granted but the conceptual tension it creates against the background of time''s presumed homogeneity calls for an explanation of temporal becoming. (...) Here, it is approached with the help of a claim to the effect that the instant (moment) itself has a structure isomorphic to that of time as a whole. Then the asymmetry of past and future in regard to temporal becoming is associated with the internal structure of the very moment, and not with external relations between different moments of time. In this paper ideas of ancient atomism and contemporary dialectics are brought together. It is for the sake of a contrast to what is known as logical atomism that I choose to call this view dialectical atomism. The latter admits dialectical contradictions and, so far as the logical status of contradictions is concerned, bears reference to paraconsistent logics. In the paper there is an outline of a method of converting any consistent axiomatic formal system into a paraconsistent theory. (shrink)

Continuous recordings of brain electrical activity were obtained from a group of 176 patients throughout surgical procedures using general anesthesia. Artifact-free data from the 19 electrodes of the International 10/20 System were subjected to quantitative analysis of the electroencephalogram (QEEG). Induction was variously accomplished with etomidate, propofol or thiopental. Anesthesia was maintained throughout the procedures by isoflurane, desflurane or sevoflurane (N = 68), total intravenous anesthesia using propofol (N = 49), or nitrous oxide plus narcotics (N = 59). A set (...) of QEEG measures were found which reversibly displayed high heterogeneity of variance between four states as follows: (1) during induction; (2) just after loss of consciousness (LOC); (3) just before return of consciousness (ROC); (4) just after ROC. Homogeneity of variance across all agents within states was found. Topographic statistical probability images were compared between states. At LOC, power increased in all frequency bands in the power spectrum with the exception of a decrease in gamma activity, and there was a marked anteriorization of power. Additionally, a significant change occurred in hemispheric relationships, with prefrontal and frontal regions of each hemisphere becoming more closely coupled, and anterior and posterior regions on each hemisphere, as well as homologous regions between the two hemispheres, uncoupling. All of these changes reversed upon ROC. Variable resolution electromagnetic tomography (VARETA) was performed to localize salient features of power anteriorization in three dimensions. A common set of neuroanatomical regions appeared to be the locus of the most probable generators of the observed EEG changes. (shrink)

The globalizations of capital markets in the last 20 years has led to a historic degree of financial integration in the world. It is clear, however, that globalization is not conducive to a complete homogeneity of financial markets and institutions.

Scandals and unethical behavior in financial institutions erode confidence in such firms. Relying on (...) neoinstitutional literature, this article focuses on the link between corruption and organizational isomorphism in financial institutions in emerging countries.

Our structural equation model is based on empirical research in financial institutions in emerging countries.

We propose adding a temporal dimension to stakeholder management theory, and assess the implications thereof for firm-level competitive advantage. We argue that a firm’s competitive advantage fundamentally depends on its capacity for stakeholder management related, transformational adaptation over time. Our new temporal stakeholder management approach builds upon insights from both the resource-based view (RBV) in strategic management and institutional theory. Stakeholder agendas and their relative salience to the firm evolve over time, a phenomenon well understood in the literature, and requiring (...) what we call level 1 adaptation. However, the dominant direction of stakeholder pressures can also change, namely, from supporting resource heterogeneity at the firm level to fostering industry homogeneity, and vice versa. When dominant stakeholder pressures shift from supporting heterogeneity towards stimulating homogeneity in industry, the firm must engage in level 2 or transformational adaptation. Stakeholders typically provide valuable resources to the firm in an early stage . Without these resources, which foster heterogeneity (in line with RBV thinking), the firm would not exist. At a later stage , stakeholders also contribute to inter-firm homogeneity via isomorphism pressures (in line with institutional theory thinking). Adding a temporal dimension to stakeholder management theory has far reaching implications for this theory’s practical relevance to senior level management in business. (shrink)

Recently Samuel Richmond, generalizing Nelson Goodman, has proposed a measure of the simplicity of a theory that takes into account not only the polymorphicity of its models but also their internal homogeneity. By this measure a theory is simple if small subsets of its models exhibit only a few distinct (i.e., non-isomorphic) structures. Richmond shows that his measure, unlike that given by Goodman's theory of simplicity of predicates, orders the order relations in an intuitively satisfactory manner. In this note (...) I formalize his presentation and suggest an improvement designed to overcome certain technical difficulties. (shrink)

This paper investigates the semantics of tense and aspect in Romance languages. Its goal is to develop a compositional, model-theoretic semantics for tense and temporal adverbs which is sensitive to aspectual distinctions. I will consider durative adverbial distributions and aspectual contrasts across different morphological tense forms. I will examine tense selection under habitual meanings, generic meanings and state of result constructions. In order to account for these facts I will argue that temporal homogeneity plays a fundamental role in tense (...) selection in Romance languages. (shrink)

It is widely agreed that generics tolerate exceptions. It turns out, however, thatexceptions are tolerated only so long as they do not violate homogeneity:when the exceptions are not concentrated in a salient ``chunk'''' of the domain ofthe generic. The criterion for salience of a chunk is cognitive: it is dependent onthe way in which the domain is mentally represented. Findings of psychologicalexperiments about the ways in which different domains are represented, and thefactors affecting such representations, account for judgments of (...) generic sentences,facts which cannot be explained by linguistics alone.The reason for the homogeneity requirement itself is, in turn, also dependenton cognitive considerations. Generics express default rules, and psychologicalfindings have shown that, the more homogeneous the domain, the easier it isfor subjects to infer rules about it. Thus, cognitive results form a crucial part of a comprehensive account of the meaningof a linguistic expression. (shrink)

Theoretical problems concerning concepts of systems and measurement of behavior were encountered during experimental studies of the effects of electrical stimulation of the brain on the social behavior of a monkey colony. General problems involved in the description and measurement of behavior of natural systems, and especially of organisms are discussed. In animals with differentiated brain the general process of stimulation may be divided into four subprocesses: input, throughput, transput and output. Categories of behavior, temporal and spatial units, and logical (...) rules of homogeneity for sorting data and comparing measurements and categories, are discussed. Simple behavioral units are divided into: 1. Individual a. static or postural b. dynamic or gestural 2. Social a. static b. dynamic. Complex behavior is divided into: 1. Simultaneous 2. Sequential 3. Syntactic 4. Roles. The process of interpretation of data by the observer is assumed to be dependent upon actual behavior of the system, techniques of observation and experimentation, theoretical and technical processes of analysis, and synthesis and integration of data. Expression of behavior in mathematical terms insures greater accuracy than descriptive methods and enables data to be processed with computers. (shrink)

We describe a way of constructing models for the continuum which does not require an underlying structure of points. With a condition of spatial homogeneity the models have the mathematical structure of a sheaf.

This study of biological laboratory is focussed on the biological experiment. By confronting the real conditions of life science experiments with an ideal canon of experimental principles - which is constituted by the six preconceptions of separation, manipulation, control, distance, reproduction and homogeneity - the differences and specialities of biological experimentation are examined. This special constitution of biological experiments in the laboratory is a reaction of the special conditions of biological phenomena too. In a co-evolutionary process of trial-and-error improvement (...) of laboratory actions not only technical points but also natural conditions are impressed on the methodical executions.

Henry Hansmann has claimed we have reached the “end of history” in corporate law, organized around the “widespread normative consensus that corporate managers should act exclusively in the economic interests of shareholders.” In this paper, I examine Hansmann’s own argument in support of this view, in order to draw out its implications for some of the traditional concerns of business ethicists about corporate social responsibility. The centerpiece of Hansmann’s argument is the claim that ownership of the firm is most naturally (...) exercised by the group able to achieve the lowest agency costs, and that homogeneity of interest within the ownership group is the most important factor in achieving lower costs. He defends this claim through a study of cooperatives, attempting to show that homogeneity is the source of the competitive advantage most often enjoyed by shareholders over other constituency groups, such as workers, suppliers and customers, when it comes to exercising control over the firm. Some business ethicists, impressed by this argument, have taken it to be a vindication of Milton Friedman’s claim that profit-maximization is the only “social responsibility” of management. I would like to suggest that this conclusion does not follow, and that the “Hansmann argument” lends itself to a less minimalist view, what I refer to as a “market failures” approach to business ethics.

This paper considers the question: what becomes of the notion of a logic as a way of codifying valid arguments when the customary assumption is dropped that the premisses and conclusions of these arguments are statements from some single language? An elegant treatment of the notion of a logic, when this assumption is in force, is that provided by Dana Scott's theory of consequence relations; this treatment is appropriately generalized in the present paper to the case where we do not (...) make this assumption of linguistic homogeneity. Several applications of the resulting concept of a heterogeneous logic are suggested, but the main emphasis is on the formal development. One topic touched on is a certain contrast between the boolean and the intensional sentence-connectives in this more general setting. (shrink)

The dynamics of single populations up to ecosystems, are often described by one or a set of non-linear ordinary differential equations. In this paper we review the use of bifurcation theory to analyse these non-linear dynamical systems. Bifurcation analysis gives regimes in the parameter space with quantitatively different asymptotic dynamic behaviour of the system. In small-scale systems the underlying models for the populations and their interaction are simple Lotka-Volterra models or more elaborated models with more biological detail. The latter ones (...) are more difficult to analyse, especially when the number of populations is large. Therefore for large-scale systems the Lotka-Volterra equations are still popular despite the limited realism. Various approaches are discussed in which the different time-scale of ecological and evolutionary biological processes are considered together. (shrink)

São muitas e, até hoje, muito controvertidas as opiniões referentes à função e ao lugar sistemático da filosofia da história de Kant no todo do seu projeto crítico-transcendental; nem há consenso quanto à importância ou relevância filosófica dos diversos escritos em que Kant aborda e defende os seus teoremas histórico- políticos. – No presente trabalho, pretende-se interpretar a “doutrina” histórico-filosófica kantiana – não obstante o seu caráter fragmentário e até aparentemente nem sempre coerente – na perspectiva da sua possível homogeneidade (...) e compatibilidade com os elementos centrais da própria teoria-base transcendental. Isso significa, antes de mais nada, ler os respectivos teoremas não como resultados de um raciocínio dogmático baseado num saber do processo histórico, mas como um conjunto de teses e postulados baseados no mero suposto subjetivo-racional de um progresso, ou seja, na idéia não só da possibilidade mas da necessidade (subjetiva) da razão de implantar princípios racionais na história.

ABSTRACT There are many different and controversial opinions about the function and the systematic place of Kant’s philosophy of history in the context of his critical-transcendental project on the whole, as well as about the philosophic relevance of his historical-political writings. – This paper aims to interpret Kant’s historical-philosophical “doctrine” – in despite of its fragmentary character and of some apparent incoherences – in the horizon of its possible homogeneity and compatibility with the central elements of the basic transcendental theory. That means, above all: read the theorems in question not as results of a dogmatic thought based on the knowledge of historical processes, but as a set of thesis and postulates based on the mere subjective- rational supposition of progress, that is, on the idea that it is not only possible, but a (subjective) need of reason to implant rational principles in history.

Habitat fragmentation produces isolated patches characterized by increased edge effects from an originally continuous habitat. The shapes of these patches often show a high degree of irregularity: their shapes deviate significantly from regular geometrical shapes such as rectangular and elliptical ones. In fractal theory, the geometry of patches created by a common landscape transformation process should be statistically similar, i.e. their fractal dimensions and their form factors should be equal. In this paper, we analyze 49 woodlot fragments (Pinus sylvestris L.) (...) in the Belgian Kempen region to study the direct relationship between a transformation process and the concomitant patch geometry. Although the fractal dimension of the woodlots is scattered (i.e. they are not statistically similar), the perimeter-area relation of the fragments is characterized by a single, ‘dimension-like’ exponent. This exponent suggests a certain shape homogeneity among the patches, which is confirmed by the absence of hierarchical levels associated with sharp increases of the fractal dimension at scale transitions. The interaction of different natural (soil factor, vegetation type) and anthropogenic (afforestation, urbanization) processes during patch development is assumed to have generated this feature. Comparison of the area and perimeter fractal dimension with an ecological index for habitat quality, the interior-to-edge ratio, shows that the fractal dimension is suitable for predicting interior habitat presence, which is more likely for patches with smooth perimeters and compact areas. The ratio of the area to the perimeter fractal dimension confirms this observation, with high values for high interior-to-edge ratios, characteristic for regularly shaped patches. (shrink)

In ecology, if the considered area or space is large, the spatial distribution of individuals of a given plant species is never homogeneous; plants form different patches. The homogeneity change in space or in time (in particular, the related change-point problem) is an important research subject in mathematical statistics. In the paper, for a given data system along a straight line, two areas are considered, where the data of each area come from different discrete distributions, with unknown parameters. In (...) the paper a method is presented for the estimation of the distribution change-point between both areas and an estimate is given for the distributions separated by the obtained change-point. The solution of this problem will be based on the maximum likelihood method. Furthermore, based on an adaptation of the well-known bootstrap resampling, a method for the estimation of the so-called change-interval is also given. The latter approach is very general, since it not only applies in the case of the maximum-likelihood estimation of the change-point, but it can be also used starting from any other change-point estimation known in the ecological literature. The proposed model is validated against typical ecological situations, providing at the same time a verification of the applied algorithms. (shrink)

The present studies tested the hypothesis that strong assumptions about within-category homogeneity impede children’s recognition of the inductive value of diverse samples of evidence. In Study 1a, children (7-year-olds) and adults were randomly assigned to receive a prime emphasizing within-category variability, a prime emphasizing within-category similarities, or to not receive a prime. Only following the variability prime, children demonstrated a reliable preference for evaluating diverse over nondiverse samples to determine whether there is support for a category-wide generalization. Adults demonstrated (...) a robust preference for diverse samples in all conditions. These effects extended beyond the specific categories included in the prime, as well as to multiple types of test questions. Study 1b demonstrated that priming variability leads children to select diverse samples only when doing so is informative for induction. Implications for conceptual development are discussed.

Teleological variations of non-deterministic processes are defined. The immediate past of a system defines the state from which the ordinary (non-teleological) dynamical law governing the system derives different possible present states. For every possible present state, again a number of possible states for the next time step can be defined, and so on. After k time steps, a selection criterion is applied. The present state leading to the selected state after k time steps is taken to be the effective present (...) state. Hence, the present state of a system is defined by its past in the sense that the past determines the possible states that are to be considered, and by its future in the sense that the selection of a possible future state determines the effective present state. A system that obeys this type of teleological dynamics may have significantly better performance than its non-teleological counterpart. The basic reason is that evolutions that are less optimal for the present time step, but which lead to a higher optimality after k time steps, may be preferred. This abstract concept of teleology is implemented for two concrete systems. First, it is applied to a general method for function approximation and classification problems. The method at issue treats all problems handled by conventional connectionism, and is suited for information with inner structure also. Second, it is applied to a dynamics in which forms of maximal homogeneity have to be produced. The relevance of the latter dynamics for generative art is illustrated. The teleology is `deep' in the sense that it is situated at the cellular level, in contradistinction with the teleology that is usually met in cognitive contexts, and which refers to macroscopic processes such as making plans. It is conjectured that deep level teleology is useful for machines, even though the issue if natural systems use this teleology is left open. (shrink)

The present paper aims at addressing a crucial legal conflict in the information society: i.e., the conflict between security and civil rights, which calls for a “fine and ethical balance”. Our purpose is to understand, from the legal theory viewpoint, how a fine ethical balance can be conceived and what the conditions for this balance to be possible are. This requires us to enter in a four-stage examination, by asking: (1) What types of conflict may be dealt with by means (...) of balancing? (2) What is meant by balancing? Is it a metaphor that hides and dissimulates discretionary powers and subjective decisions or a rational instrument that helps us cope with conflicts between fundamental values and interests? (3) What models of balancing are available to us? Are these models irreducible to each other? What can provide us with a common understanding of different models of balancing? (4) How can the crucial issues of rational controllability, predictability, and homogeneity of legal decisions be dealt with? Our paper will try to answer those questions by trying to reconstruct the act of balancing in terms of a rational legal reasoning, which relies upon information. In fact, every judicial decision contains some information that is delivered to the legal system: that information may serve as the basis for future evaluations, decisions, and actions, and thus influence the way we recognize and hence we protect our values, interests, and rights. In this perspective, our examination will attempt to understand those questions in informational terms. This informational treatment can provide us with a more universalistic understanding of those issues and offer us a novel way to conceptually deal with them. To this aim, we will avail yourself of Luciano Floridi’s philosophy of information: notably, we believe his constructionist conception of epistemology is crucial, based on the Maker’s Knowledge approach and his solution of the upgrading problem (i.e., from information to knowledge) in terms of a network theory of account. The informational approach will help us having a better understanding of the balance between competing interests. (shrink)

Since the close of the cold war, there seems to be a certain constant in the conflicts that have marked multi-national conferences. Again and again, we see the smaller states opposing the efforts of the larger to determine the structures of their relations. One of the factors of this opposition is their fear of losing their identity. In a world increasingly determined by global interests, cultural and economic particularity seems to be a luxury that few can afford. For many, the (...) name of this fear is “globalization.” They take the term as signifying a process that threatens to replace their individuality with an empty universality. Benignly regarded, globalization promises a world where we all drink the same soft-drinks, wear the same jeans, watch the same movies, and listen to the same music--all of it, presumably American. A darker vision sees within such homogeneity the dangers of totalitarianism. As Hannah Arendt noted, totalitarian systems presuppose a certain uniformity to achieve their effect. The ideal they tend to is that of reducing their subjects to a situation analogous to marbles on a table. The slightest tilt will make the marbles roll in the same direction. When citizens lose their individuality, when each is stripped of his particularizing relations to his neighbors, then the state gains the ability to apply a uniform power to produce a uniform effect. Here, the controllability of the response is directly proportional to the reduction of each of us to every one else. In this less benign view, the globalization that American capitalism promotes is actually a new form of totalitarianism. After the fascism and communism of the previous century, its third, capitalistic wave is now upon us. We need not accept this dark vision to feel uneasy about the emerging global community. At the root of our current disquiet is, I think, a sense that an aspect of our selfhood is under attack. The fear is that when we do become just like everyone else, we will lose our privacy..

This paper provides a critical analysis of the modelling strategies adopted in the trade?growth literature. Despite a huge number of econometric studies, there is a growing dissatisfaction with such studies and serious questions over what exactly has been learnt from them. Econometric work has been criticized for, amongst other things, its lack of clear relationship to underlying theory and questionable use of proxies for trade policy. It is frequently unclear what hypothesis is being tested in this literature. Universalist assumptions of (...) the effects of trade policy have been undermined by earlier confident predictions of the effects of trade liberalization having not been borne out systematically by the past quarter century experience. This paper argues that the results of econometric analyses of the trade?growth relations are indicative of fundamental difficulties with the cross-country modeling strategy. The failure to find a clear trade?growth relationship consistently across countries and between time periods could, though, provide the starting point for further investigation. Alternative modelling strategies are considered here. An incipient research agenda has proposed a return to the comparative case study approach, incorporating the institutional and historical specificities of each country and thereby (implicitly or explicitly) rejecting universalist or homogeneity assumptions. Nevertheless, such a careful work has not been able thus far to provide a clear research agenda; there has been no consensus on the conclusions or methods of this approach in relation to trade?growth linkages. Whilst this has undoubtedly stimulated further research it has yet to produce a clear corpus of alternative work. This paper provides a critical analysis of the strategies adopted to address the theoretical and econometric critiques advanced of this work. (shrink)

Zhuangzi and Henry David Thoreau share a critical interest in the relations between wandering, nature, and experience. Their attitudes toward nature provide a basis for their views of human well-being, which in turn inform their attitudes toward language, society, and politics. Both celebrate nature as a source of constant novelty, change, and nourishing life. These values clash against social conformity and political homogeneity. For both Zhuangzi and Thoreau, how we experience life is already constitutive of human well-being. Wandering thus (...) provides a unique vision of freedom, one that binds experience, nature, and social-political criticism. (shrink)
