This essay proposes a design perspective on argumentation, intended as complementary to empirical and critical scholarship. In any substantive domain, design can provide insights that differ from those provided by scientific or humanistic perspectives. For argumentation, the key advantage of a design perspective is the recognition that humanity’s natural capacity for reason and reasonableness can be extended through inventions that improve on unaided human intellect. Historically, these inventions have fallen into three broad classes: logical systems, scientific methods, and disputation frameworks. (...) Behind each such invention is a specifiable “design hypothesis”: an idea about how to decrease error or how to increase the quality of outcomes from reasoning. As problems in contemporary argumentation practice become more complex, design thinking rises in relevance and importance. A design research agenda in argumentation would focus on theorizing design innovations and on evaluating design hypotheses. (shrink)

How do Dutch people let each other know that they disagree? What do they say when they want to resolve their difference of opinion by way of an argumentative discussion? In what way do they convey that they are convinced by each other’s argumentation? How do they criticize each other’s argumentative moves? Which words and expressions do they use in these endeavors? By answering these questions this short essay provides a brief inventory of the language of argumentation in Dutch.

Contemporary reasoning about health is infused with the work products of experts, and expert reasoning about health itself is an active site for invention and design. Building on Toulmin’s largely undeveloped ideas on field-dependence, we argue that expert fields can develop new inference rules that, together with the backing they require, become accepted ways of drawing and defending conclusions. The new inference rules themselves function as warrants, and we introduce the term “warranting device” to refer to an assembly of the (...) rule plus whatever material, procedural, and institutional resources are required to assure its dependability. We present a case study on the Cochrane Review, a new method for synthesizing evidence across large numbers of scientific studies. After reviewing the evolution and current structure of the device, we discuss the distinctive kinds of critical questions that may be raised around Cochrane Reviews, both within the expert field and beyond. Although Toulmin’s theory of field-dependence is often criticized for its relativism, we find that, as a matter of practical fact, field-specific warrants do not enjoy immunity from external critique. On the contrary, they can be opened to evaluation and critique from any interested perspective. (shrink)

This paper develops the foundations of the descriptive set theory of countable Borel equivalence relations on Polish spaces with particular emphasis on the study of hyperfinite, amenable, treeable and universal equivalence relations.

Argument is a pervasive feature of human interaction, and in its natural contexts of occurrence, it is organized around the management of disagreement. Since disagreement can occur around any kind of speech act whatsoever, not all arguments involve a claim supported by reasons; many involve standpoints attributed to someone but claimed by no one. And although truth and validity are often at issue in naturally occurring arguments, these do not exhaust the standards to which arguers are held. Arguers hold one (...) another accountable for cooperating in the management of disagreement, infusing argumentation with a natural normativity that exists apart from any theorized appraisal standard applied to the claim-reason relationship. Argumentation’s natural normativity is visible not only in how arguments unfold in interaction but also in how humanity continuously strives to improve its methods of disagreement management.

In normative pragmatics, a kind of empirical discourse analysis organized by normative theory, the analysis of any communication process begins with an idealized model of the discourse that can be compared with actual practices. Idealizations of argumentation can be found, among other places, in theoretical descriptions of ‘critical discussion’ and other dialogue types. Comparing ideal models with actual practices can pinpoint defects in the models (leading to theoretical refinements), but it can also identify deficiencies in practice. This latter possibility invites (...) redesign around well-justified idealizations. This paper outlines an approach to the design of discourse processes and illustrates the approach with contrastive analysis of several recently developed protocols for discussion and debate on the worldwide web.

“Black box argument” is a metaphor for modular components of argumentative discussion that are, within a particular discussion, not open to expansion. In public policy debate such as the controversy over abstinence-only sex education, scientific conclusions enter the discourse as black boxes consisting of a result returned from an external and largely impenetrable process. In one way of looking at black box arguments, there is nothing fundamentally new for the argumentation theorist: A black box argument is very like any other (...) appeal to authority, and what might be said about any particular form of black box will turn out to be a particularized version of what might be said about evaluating arguments based on authority. But in another way of looking at black box arguments, they are a constantly evolving technology for coming to conclusions and making these conclusions broadly acceptable. Black boxes are to argumentation what material inventions are to engineering and related sciences. They are anchored in and constrained by fundamental natural processes, but they are also new things that require theoretical explication and practical assessment. (shrink)

Digressions in argumentative discussion are a kind of failure of relevance. Examination of what actual cases look like reveals several properties of argumentative relevance: (1) The informational relevance of propositions to the truth value of a conclusion should be distinguished from the pragmatic relevance of argumentative acts to the task of resolving a disagreement. (2) Pragmatic irrelevance is a collaborative phenomenon. It does not just short-circuit reasoning; it encourages a failure to take up the demands of an argumentative task. (3) (...) Pragmatic irrelevance can occur not simply by the absence of a connection between what is said and some standpoint in dispute, but also by the presence of a connection between what is said and a competing use of the information. (4) Pragmatic relevance must be accomplished through communicative action. (shrink)

Cross cultural studies have played a pivotal role in elucidating the extent to which behavioral and mental characteristics depend on specific environmental influences. Surprisingly, little field research has been carried out on a fundamentally important perceptual ability, namely the perception of biological motion. In this report, we present details of studies carried out with the help of volunteers from the Mundurucu indigene, a group of people native to Amazonian territories in Brazil. We employed standard biological motion perception tasks inspired by (...) over 30 years of laboratory research, in which observers attempt to decipher the walking direction of point-light (PL) humans and animals. Do our effortless skills at perceiving biological activity from PL animations, as revealed in laboratory settings, generalize to people who have never before seen representational depictions of human and animal activity? The results of our studies provide a clear answer to this important, previously unanswered question. Mundurucu observers readily perceived the coherent, global shape depicted in PL walkers, and experienced the classic inversion effects that are typically found when such stimuli are turned upside down. In addition, their performance was in accord with important recent findings in the literature, in the abundant ease with which they extracted direction information from local motion invariants alone. We conclude that the effortless, veridical perception of PL biological motion is a spontaneous and universal perceptual ability, occurring both inside and outside traditional laboratory environments.

We examined the attitudes of 600 students in large introductory algebra and psychology classes toward an actual or hypothetical cheating incident and the subsequent retake procedure. Overall, 57% of students in one class and 49Y0 in the other reported that they either cheated or would have cheated if given the opportunity. More men (59%) than women (53%) reported cheating or potential cheating. Students who had actually experienced a retake procedure to handle cheating were more satisfied with such a procedure than (...) others were about a hypothetical situation. Despite having a retake, cheaters were significantly more likely than noncheaters to predict that they would cheat again. Results suggest that instructors who require a retake following extensive cheating should devote class time to a discussion of the issue and all possible alternatives. (shrink)

Assume ZF + AD +V=L and letκ< Θ be an uncountable cardinal. We show thatκis Jónsson, and that if cof = ω thenκis Rowbottom. We also establish some other partition properties.

The work of Paulo Freire is associated with themes of oppression and liberation, and his critical pedagogy is visionary in its attempts to bring about social transformation. Freire has created a theory of education that embeds these issues within social relations that center around both ideological and material domination. In this review essay, Sue Jackson explores three books: Freire’s final work Pedagogy of Indignation; Cesar Augusto Rossatto’s Engaging Paulo Freire’s Pedagogy of Possibility, which attempts to engage Freire’s pedagogy of possibility; (...) and C.A. Bowers and Frederique Apffel‐Marglin’s edited collection Re‐thinking Freire, which asks readers to reconsider Freire’s work in light of globalization and environmental crises. Jackson questions the extent to which Freire’s pedagogical approaches are useful to educators as well as to “the oppressed,” and whether challenges to re‐think Freire can lead to new kinds of critical pedagogies.

Christine Delphy is a major architect of materialist feminism, a radical feminist perspective which she developed in the context of the French women's movement in the late 1960s and early 1970s. She has always been controversial and continues to make original and challenging contributions to current feminist debates. This informative volume profiles Delphy and discusses topics including her opposition to the idea that femininity and masculinity are natural phenomena. Her insistence that women and men are social categories, defined by the (...) hierarchical relationship between them rather than by biology, typifies the materialist school within French feminism. In this lucid introduction to Delphy's work, Stevi Jackson recounts the events in Delphy's life as a feminist activist and the social and political context of her work. This text is essential reading for anyone with an interest in feminism or cultural history, this is a readable and accessible introduction to a key thinker in the modern women's movement. (shrink)

We formulate and prove a combinatorial property assuming AD + V = L(R). As a consequence, we show that every regular κ which is either a Suslin cardinal or the successor of a Suslin cardinal is δ 2 1 -supercompact. In particular, all the projective ordinals δ 1 n are δ 2 1 -supercompact.

Girotto and Legrenzi's 1993 facilitation effect for their SARS version of Wason s THOG problem a disjunctive reasoning task was examined. The effect was not replicated when the standard THOG problem instructions were used in Experiments 1 and 2. However, in Experiment 3 when Girotto and Legrenzi's precise instructions were used, facilitation was observed. Experiment 4 further investigated the role of the type of instructions in the observed facilitation. The results suggest that such facilitation may result from attentional factors rather (...) than the use of a combinatorial analysis in the problem. (shrink)

We survey some results and problems arising from a classic problem of Steinhaus: Is there a subset S of R 2 such that each isometric copy of mathbbZ 2 (the lattice points in the plane) meets S in exactly one point.

We show that all the projective ordinals $\delta^1_n$ are supercompact through their supremum $\aleph_{\varepsilon 0}$, and a ways beyond.

Studies of implicit learning have shown that individuals exposed to a rule-governed environment often learn to exploit 'rules' which describe the structural relationship between environmental events. While some authors have interpreted such demonstrations as evidence for functionally separate implicit learning systems, others have argued that the observed changes in performance result from explicit knowledge which has been inadequately assessed. In this paper we illustrate this issue by considering one commonly used implicit learning task, the Serial reaction time task, and outline (...) what we see as an important problem associated with each of the commonly used methods used to assess explicit knowledge. This is that each measure requires a form of response which is dependent on the subjects having some knowledge of the serial-order of the sequence. We argue that such methods, or more specifically their analyses, seriously underestimate other sources of knowledge, which may be available to subjects during their performance of the SRT task. In support of this argument we demonstrate that subjects' serial-order knowledge can, in principle, be independent of subjects' knowledge of the statistical structure of the sequence, and we propose an alternative method for analysing performance on the Generate task which avoids this problem.

Western philosophy’s relationship with prisons stretches from Plato’s own incarceration to the modern era of mass incarceration. Philosophy Imprisoned: The Love of Wisdom in the Age of Mass Incarceration draws together a broad range of philosophical thinkers, from both inside and outside prison walls, in the United States and beyond, who draw on a variety of critical perspectives (including phenomenology, deconstruction, and feminist theory) and historical and contemporary figures in philosophy (including Kant, Hegel, Foucault, and Angela Davis) to think about (...) prisons in this new historical era. All of these contributors have experiences within prison walls: some are or have been incarcerated, some have taught or are teaching in prisons, and all have been students of both philosophy and the carceral system. The powerful testimonials and theoretical arguments are appropriate reading not only for philosophers and prison theorists generally, but also for prison reformers and abolitionists. (shrink)

Science studies has long been concerned with the theoretical and methodological challenge of mess—the inevitable tendency of technoscientific objects and practices to spill beyond the neat analytic categories we construct for them. Nowhere is this challenge greater than in the messy world of large-scale collaborative science projects, particularly though not exclusively in their start-up phases. This article examines the complicated life and death of the WATERS Network, an ambitious and ultimately abandoned effort at collaborative infrastructure development among hydrologists, engineers, and (...) social scientists studying water. We argue in particular against the “forensic imagination,” a particular style of accounting for failure in the messy world of large-scale network development, and against two common conceptual and empirical pitfalls that it gives rise to: defaults to formalism and defaults to the future. We argue that alternative postforensic approaches to “failures” like the WATERS Network can support forms of learning and accountability better attuned to the complexities of practice and policy in the real world of scientific collaboration and network formation.

Designer Biology: The Ethics of Intensively Engineering Biological and Ecological Systems consists of thirteen chapters that address the ethical issues raised by technological intervention and design across a broad range of biological and ecological systems. Among the technologies addressed are geoengineering, human enhancement, sex selection, genetic modification, and synthetic biology.

Let E be a coanalytic equivalence relation on a Polish space X and (A n ) n∈ω a sequence of analytic subsets of X. We prove that if lim sup n∈K A n meets uncountably many E-equivalence classes for every K ∈ [ω] ω , then there exists a K ∈ [ω] ω such that ⋂ n∈K A n contains a perfect set of pairwise E-inequivalent elements.

Natural fractures can reactivate during hydraulic stimulation and interact with hydraulic fractures producing a complex and highly productive natural-hydraulic fracture network. This phenomenon and the quality of the resulting conductive reservoir area are primarily functions of the natural fracture network characteristics ; in situ stress state ; stimulation design parameters ; well architecture ; and the physics of the natural-hydraulic fracture interaction. Geomechanical models can quantify the impact of key parameters that control the extent and complexity of the conductive reservoir (...) area, with implications to stimulation design and well optimization in the field. We have developed a series of geomechanical simulations to predict natural-hydraulic fracture interaction and the resulting fracture network in complex settings. A geomechanics-based sensitivity analysis was performed that integrated key reservoir-geomechanical parameters to forward model complex fracture network generation, synthetic microseismic response, and associated conductivity paths as they evolve during stimulation operations. The simulations tested two different natural-hydraulic fracture interaction scenarios and could generate synthetic MS events. The sensitivity analysis revealed that geomechanical models that involve complex fracture networks can be calibrated against MS data and can help to predict the reservoir response to stimulation and optimize the conductive reservoir area. We analyzed a field data set and established a coupling between the geomechanics and MS within the framework of a 3D geologic model. This coupling provides a mechanics-based approach to verify MS trends and anomalies in the field, optimize conductive reservoir area for reservoir simulations, and improve stimulation design on the current well in near-real-time and well design/stimulation for future wells.

Interrogating the relationship between reading, writing and ‘conversion disorder’, this creative-critical essay explores the eversion of the glove in the work of Woolf, Genet, Freud and Derrida. Gathering together reflections on gloves and glove anaesthesia, doubles and pairs, and flowers and the death knell, it offers a series of literary, philosophical and psychoanalytic conversions in order to return to and rethink the question of ‘disorder’.

Assuming AD + (V = L(R)), it is shown that for κ an admissible Suslin cardinal, o(κ) (= the order type of the stationary subsets of κ) is "essentially" regular and closed under ultrapowers in a manner to be made precise. In particular, o(κ) ≫ κ +, κ ++ , etc. It is conjectured that this characterizes admissibility for L(R).

The Department of Health and Human Services, Office for Civil Rights enforces Section 504 of the 1973 Rehabilitation Act and Title II of the Americans with Disabilities Act. OCR works through complaint investigations and compliance reviews, as well as outreach, technical assistance, and public education to promote voluntary compliance. In the Olmstead decision of June 1999, the Supreme Court held that the ADA’s “integration regulation” requires state and local government to administer services, programs, and activities in the most integrated setting (...) appropriate to the needs of qualified individuals with disabilities. The decision changed the focus from whether a right to more integrated services exists, to under what circumstances and how services will be provided. The New Freedom Initiative announced by President Bush in February 2001 is a broadbased initiative to remove barriers to community living for people with disabilities and promote swift implementation of the Olmstead decision.
