This remarkable book is about everything from echidnas to evolution, cosmology to cooking, sex and science and spirits to Schrodinger's cat. Tyson Yunkaporta looks at global systems from an Indigenous perspective. He asks how contemporary life diverges from the pattern of creation. How does this affect us? How can we do things differently? Sand Talk provides a template for living. It's about how lines and symbols and shapes can help us make sense of the world. It's about how we (...) learn and how we remember. It's about talking to everybody and listening carefully. It's about finding different ways to look at things. Most of all it's about Indigenous thinking, and how it can save the world. (shrink)

Epistemic modals have peculiar logical features that are challenging to account for in a broadly classical framework. For instance, while a sentence of the form $$p\wedge \Diamond \lnot p$$ (‘p, but it might be that not p’) appears to be a contradiction, $$\Diamond \lnot p$$ does not entail $$\lnot p$$, which would follow in classical logic. Likewise, the classical laws of distributivity and disjunctive syllogism fail for epistemic modals. Existing attempts to account for these facts generally either under- or over-correct. (...) Some theories predict that $$ p\wedge \Diamond \lnot p$$, a so-called epistemic contradiction, is a contradiction only in an etiolated sense, under a notion of entailment that does not always allow us to replace $$p\wedge \Diamond \lnot p$$ with a contradiction; these theories underpredict the infelicity of embedded epistemic contradictions. Other theories savage classical logic, eliminating not just rules that intuitively fail, like distributivity and disjunctive syllogism, but also rules like non-contradiction, excluded middle, De Morgan’s laws, and disjunction introduction, which intuitively remain valid for epistemic modals. In this paper, we aim for a middle ground, developing a semantics and logic for epistemic modals that makes epistemic contradictions genuine contradictions and that invalidates distributivity and disjunctive syllogism but that otherwise preserves classical laws that intuitively remain valid. We start with an algebraic semantics, based on ortholattices instead of Boolean algebras, and then propose a possibility semantics, based on partial possibilities related by compatibility. Both semantics yield the same consequence relation, which we axiomatize. We then show how to lift an arbitrary possible worlds model for a non-modal language to a possibility model for a language with epistemic modals. The goal throughout is to retain what is desirable about classical logic while accounting for the non-classicality of epistemic vocabulary. (shrink)

This book considers the efficacy of the common regulatory model of the licensing regime as a means of regulating animal use in England, with a particular focus on wild animals and the regime’s ability to ensure animal welfare needs are met. Using information gleaned from over 550 inspection reports relating to the period 2008 through 2019, obtained using FOI Act requests, the book analyses the extent to which animals used by these industries are protected by law. Tyson analyses the (...) limitations present in the practical application of English legislation responsible for creating a number of relevant licensing regimes.The regimes discussed include: The Zoo Licensing Act 1981, the now repealed Welfare of Wild Animals in Travelling Circuses Regulations 2012, and the Animal Welfare Regulations 2018, introduced under the Animal Welfare Act 2006. Exploring the weakness in the use of this type of regulatory model, Tyson proposes compelling recommendations for change in future policy development. Making an important contribution to the question of enforcement of animal welfare laws, this book provides useful and original insights into the implementation of licensing regimes, and will be of particular interest to scholars of animal welfare law, animal ethics, and critical animal studies.

There is an extensive literature in social choice theory studying the consequences of weakening the assumptions of Arrow's Impossibility Theorem. Much of this literature suggests that there is no escape from Arrow-style impossibility theorems unless one drastically violates the Independence of Irrelevant Alternatives (IIA). In this paper, we present a more positive outlook. We propose a model of comparing candidates in elections, which we call the Advantage-Standard (AS) model. The requirement that a collective choice rule (CCR) be rationalizable by the (...) AS model is in the spirit of but weaker than IIA; yet it is stronger than what is known in the literature as weak IIA (two profiles alike on x, y cannot have opposite strict social preferences on x and y). In addition to motivating violations of IIA, the AS model makes intelligible violations of another Arrovian assumption: the negative transitivity of the strict social preference relation P. While previous literature shows that only weakening IIA to weak IIA or only weakening negative transitivity of P to acyclicity still leads to impossibility theorems, we show that jointly weakening IIA to AS rationalizability and weakening negative transitivity of P leads to no such impossibility theorems. Indeed, we show that several appealing CCRs are AS rationalizable, including even transitive CCRs. (shrink)

The pressure for results applied by some research funders concerns some academicians. Sometimes, for example, a sponsor requests preliminary data that the researcher is not ready to release. This paper presents three interviews — two with researchers and one with a representative from industry — dealing with these issues and makes recommendations on the basis of those interviews. It also looks briefly at the different norms that exist in industry and academia for research and communication and the tensions these can (...) cause for a scientist working simultaneously in both realms.

Whether to do business with rights violating regimes is one of many dilemmas faced by socially responsible corporations. In this article the difficult case of Myanmar is considered. Ruled for decades by a closed and sometimes brutal military elite, the country has long been subject to informal and formal sanctions. However, as sanctions have failed to trigger political reform, it is necessary to review the policy options. The focus here is on the contribution socially responsible corporations might make to change. (...) The article sketches contextual features of the case, examines the recent history and present pattern of business links with Myanmar, and assesses whether current approaches can stimulate reform. Concluding that they cannot, it considers fresh possibilities for corporate engagement. The argument is that socially responsible corporations, committed to improving individual life chances through engagement with developing societies, should undertake collaborative and principled direct investment in Myanmar. The underlying strategy and problems of codification and implementation are all analyzed. To close, the article contends that, by doing business with Myanmar’s rights violating regime, multinational corporations can extend the frontiers of global corporate social responsibility. (shrink)

Cinema Derrida charts Jacques Derrida's collaborations and appearances in film, video, and television beginning with 1983's Ghost Dance (dir. Ken McMullen, West Germany/UK) and ending with 2002's biographical documentary Derrida (dir. Dick and Ziering, USA). In the last half of his working life, Derrida embraced popular art forms and media in more ways than one: not only did he start making more media appearances after years of refusing to have his photo taken in the 1960s and 1970s, but his philosophy (...) started to draw more explicitly from visual culture and artistic endeavours. While this book offers explanations of this transition, it contends the image of "Jacques Derrida" that emerges from film and TV appearances remains spectral, constantly deferring a complete grasp of him. Tyson Stewart draws out the main tenets of spectrality from Derrida's seminal texts Of Grammatology and Specters of Marx and other writings, like Echographies of Television, in order to fill a gap in studies of Derrida and film. Throughout the book, he explains how various techniques and spectral effects such as slow motion, stillness, repetition, mise-en-abîme, direct address, and focus on body parts/bodily presence bring about a structure of spectrality wherein the past other returns to make impressions and ethical demands on the viewer. Drawing on communication theory and film and media studies, Cinema Derrida makes a major intervention in classical communication thought. (shrink)

In an educational landscape dominated by discourses and practices of learning, standardized testing, and the pressure to succeed, what space and time remain for studying? In this book, Tyson E. Lewis argues that studying is a distinctive educational experience with its own temporal, spatial, methodological, aesthetic, and phenomenological dimensions. Unlike learning, which presents the actualization of a student’s "potential" in recognizable and measurable forms, study emphasizes the experience of potentiality, freed from predetermined outcomes. Studying suspends and interrupts the conventional (...) logic of learning, opening up a new space and time for educational freedom to emerge. Drawing upon the work of Italian philosopher and critical theorist Giorgio Agamben, Lewis provides a conceptually and poetically rich account of the interconnections between potentiality, freedom, and study. Through a mixture of educational critique, phenomenological description, and ontological analysis, Lewis redeems study as an invaluable and urgent educational experience that provides alternatives to the economization of education and the cooptation of potentiality in the name of efficiency. The resulting discussion uncovers multiple forms of study in a variety of unexpected places: from the political poetry of Adrienne Rich, to tinkering classrooms, to abandoned manifestos, and, finally, to Occupy Wall Street. By reconnecting education with potentiality this book provides an educational philosophy that undermines the logic of learning and assessment, and turns our attention to the interminable paradoxes of studying. The book will be key reading for scholars in the fields of educational philosophy, critical pedagogy, foundations of education, composition and rhetoric, and critical thinking and literacy studies.

In this article, we tell a story about incompleteness in modal logic. The story weaves together an article of van Benthem, “Syntactic aspects of modal incompleteness theorems,” and a longstanding open question: whether every normal modal logic can be characterized by a class of completely additive modal algebras, or as we call them, ${\cal V}$-baos. Using a first-order reformulation of the property of complete additivity, we prove that the modal logic that starred in van Benthem’s article resolves the open question (...) in the negative. In addition, for the case of bimodal logic, we show that there is a naturally occurring logic that is incomplete with respect to ${\cal V}$-baos, namely the provability logic $GLB$. We also show that even logics that are unsound with respect to such algebras do not have to be more complex than the classical propositional calculus. On the other hand, we observe that it is undecidable whether a syntactically defined logic is ${\cal V}$-complete. After these results, we generalize the Blok Dichotomy to degrees of ${\cal V}$-incompleteness. In the end, we return to van Benthem’s theme of syntactic aspects of modal incompleteness. (shrink)

In this paper, Tyson E. Lewis challenges the dominant theoretical and practical educational responses to globalization. On the level of public policy, Lewis demonstrates the limitations of both neoliberal privatization and liberal calls for rehabilitating public schooling. On the level of pedagogy, Lewis breaks with the dominant liberal democratic tradition which focuses on the cultivation of democratic dispositions for cosmopolitan citizenship. Shifting focus, Lewis posits a new location for education out of bounds of the common sense of public versus (...) private, nationalism versus cosmopolitanism, inclusion versus exclusion, human versus civil rights. This is the space of the commonwealth whose actors cannot be identified as ‘citizens’ but are rather the anonymous multitude. In conclusion, Lewis finds a model for organizing this commonwealth in the work of Ivan Illich, whose learning networks speak to the urgent political and pedagogical need for exodus from the conceptual vocabulary that defines much of the contemporary field of educational theory.

The concept of empathy in history education involves students in the attempt to think within the context of historical agents’ particular predicaments. Tracing the concept’s philosophical heritage to R. G. Collingwood’s philosophy of history and ‘re-enactment doctrine’, this article argues that our efforts in history classrooms to understand historical agents by their own standards are constrained by a tension that arises out of the need to disconnect ourselves from a present that provides the very means for understanding the past. Though (...) rather than serving to undermine the concept, it is proposed that the moderate hermeneutics of H.-G. Gadamer, through a positive conception of prejudice, tradition and temporal distance, transforms the factors typically seen as inhibitors to empathy’s operation into those that potentially enable it. The article aspires to shed new light on what is at play when history students engage in the intellectually demanding task of empathizing in history. (shrink)

In this paper I shift the center of utopian debates away from questions of ideology towards the question of power.

Arguing for a new hermeneutic of biopolitics in education, I then apply this lens to evaluate the educational philosophy of John Dewey. In conclusion, the paper suggests that while Hardt and Negri are missing an educational theory, John Dewey is (...) missing a concept of democracy adequate to the biopolitical struggles of the multitude. Thus, I call for a synthesis of Dewey and Hardt and Negri in order to generate a biopedagogical practice beyond both traditional models of education as well as current standardization. (shrink)

In an effort to disrupt the hegemonic dominance of learning theory, in this article Tyson Lewis explores the unique educational logic of studying. Drawing on the work of Giorgio Agamben, we can understand the operation of study as one of suspension through three modes: preferring not; no longer, not yet; and as not. But the relationship between the operation of suspension and the everyday mode of learning remains an open question requiring further analysis. In order to accomplish this task, (...) it is important to remember that for Agamben, study is a kind of profanation or improper life. Through examining Heidegger's analytic of Dasein's everyday being, Lewis demonstrates that the nature of study is always already saturated with the everyday, and is itself a contaminated process that is neither simply everyday living nor “authentic” existence. To be absolutely precise, the studier engages in idle talk, is curious, and is caught up in ambiguity in order to explore the seemingly uninhabitable zone that rests between everyday falling and authentically standing. Lewis concludes by offering Agamben's own work as a paradigm of study, illustrating how the smallest of freedoms opens to the studier: the freedom to dwell in potentiality. (shrink)

The history of the idea of progress and the history of the concept of progress are two different things, not least because they emanate from considerably different intellectual traditions. In anglophone history of ideas, progress has typically been viewed as a belief. Historians of ideas explore the past evaluating the extent to which a given society met certain conditions of belief. By contrast, in the history of concepts as developed by Reinhart Koselleck, progress has occupied the dual role of a (...) ‘basic concept’ that grasps modern sociopolitical reality and a ‘collective singular’ that aggregates previous and adjacent meanings in the one linguistic unit. This article compares these two historical research programmes, highlights their merits and deficiencies, and concludes by offering a new approach to the history of concepts as suggested by R.G. Collingwood’s theory of a scale of forms. In each of the approaches to the history of ideas and concepts addressed, particular attention is given to the problem of what qualifies as progress, and thus to a longstanding problem concerning the attribution of progress to past societies routinely excluded from its history, including those left out by Koselleck’s conventional secular-modern thesis.

In response to the growing emphasis on learning outcomes, life-long learning, and what could be called the learning society, scholars are turning to alternative educational logics that problematize the reduction of education to learning. In this article, we draw on these critics but also extend their thinking in two ways. First, we use Giorgio Agamben and Gilles Deleuze to posit two educational logics—tinkering and hacking, respectively—that suspend and render inoperative learning logics, expectations, and evaluative metrics. Second, we argue that contemporary (...) artists and designers such as Katerina Kamprani and Grupo de Arte Callejero have much to offer educational philosophers and theorists interested in practices of suspension. In conclusion, we suggest ways in which educators can tinker with and hack into the curriculum by playing with the quintessential embodiment of learning: the test. (shrink)

Inoperative Learning draws upon the movement towards a weak philosophy that is currently gaining ground in educational philosophy: this weak philosophy does not offer a set of solutions or guidelines for improving educational outcomes, but rather renders assumptions about the theory-practice coupling that is so popular in contemporary education inoperative. By arguing that such logic reduces education to merely instrumental ends, which can only be assessed in terms of predefined measurement tools, this book presents a challenge to contemporary notions of (...) education as learning. There are various forms of inoperative education that temporarily suspend the goal-directedness of learning. From the perspective of learning, the neutralization of progress, growth, and maturity would usually be seen as obstacles needing to be overcome on the path toward set goals. Yet Lewis argues that a serious investigation of inoperativity opens up possibilities that would be otherwise unavailable in a world fixated on the question of learning. In dialogue with philosophers (Agamben, Benjamin, and Esposito), as well as authors (Kafka and Walser), and qualitative researchers (Lather), Lewis turns our collective attention to what remains when concepts such as learning, child development, teacher effectivity, and personal growth are left idle. Inoperative Learning presents a radical rewriting of educational possibilities. It should therefore be of great interest to educational researchers and educational philosophers concerned with the question of alternative logics of education beyond learning. The book may also be of interest to educational policy specialists who are looking for new and innovative forms of critique and analysis. (shrink)

History educators find themselves in the peculiar situation of wishing to introduce students to the history discipline while lacking a clear conception of the features intrinsic to historical inquiry across its various specialisations and subject matters. In affirming that no one methodological charter hangs in the corridors of academic history departments, we fail to provide an adequate justification for an education in history. The doctrine that history is an exercise in disciplined knowledge, a specific way of knowing, is weakened by (...) disciplinary disquietude and dissimilitude. Three features impress themselves upon all who inquire into the past. In the learning and teaching of history, these three features assume a distinct structural shape. First, colligation consists in grouping the events and concepts to be studied according to their shared purposes. Second, historical distance, intimately tied up with tradition and collective memory, provides the means for identifying a past separate from the present to be studied in its own right. Third, reconstruction describes the process of supplying individual content to the general categories illuminated by the earlier stages. To work knowingly in this structure of historical inquiry offers no solutions to the problems of historical thinking, it is to work productively within these problems. (shrink)

Investors with a pro-social or sustainability agenda increasingly attempt to influence firm managers to adopt socially responsible behavior, either through positive/reward tactics or negative/punishment tactics. This paper considers how investors can use each approach to differentially influence managers to make more CSR investments. The paper uses game theory with an all-pay contest structure to model how a large institutional investor could reward firms for CSR activities by creating a socially responsible investment fund (reward contest) or punish firms via shareholder activism (...) (punishment contest). We identify conditions under which the punishment contest induces a higher level of CSR activity among firms compared to the reward contest. Managers bearing substantial private costs stemming from the activism is one such condition. Spillover effects are seen as the other managers in the economy engage in CSR to avoid being punished by the investor’s activism. This level of engagement is not the case when rewards are used—only those managers with an expectation of being rewarded increase their CSR activity in that scenario. This suggests, for example, that incorporating thresholds or tiers (e.g. gold, silver, and bronze-level winners) can increase the effectiveness of reward contests. Implications for designing both positive and negative CSR inducements are explored. We also identify the ethical dilemmas that relate to such influence attempts. (shrink)

Walter Benjamin's Antifascist Education is the first comprehensive analysis of educational themes across the entirety of the critical theorist's diverse writings. Starting with Benjamin's early reflections on teaching and learning, Tyson E. Lewis argues that the aesthetic and cultural forms to which Benjamin so often turned-namely, radio broadcasts, children's theatrical productions, collections, cityscapes, public cinemas, and word games-swell with educational potentialities. What emerges from Lewis's reading is a constellational curriculum composed of minor practices such as poor teaching, absentminded learning, (...) and nondurational studying. This curriculum carries political significance, offering an antidote to past and present forms of fascist manipulation, hardness, and coldness. Walter Benjamin's Antifascist Education is a testimony to Benjamin's belief that "everyone is an educator and everyone needs to be educated and everything is education.". (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 23 (2003) 101-116 [Access article in PDF] Persons and Awareness Tyson Anderson Saint Leo University The aim of this essay is to relate Christianity and Buddhism through a consideration of two key terms, "persons" and "awareness," the first being central for Christianity and the second being central for Buddhism.The first thing that needs to be noticed is the relatively indefinable character of these words. I of (...) course intend to give as clear an indication as is possible concerning their meaning, but as I considered some of the important concepts that are involved in the topic—language, world, love, understanding—I began to realize that we are surely in the realm of mystery here. By "mystery" I mean something that we can understand somewhat but cannot comprehend, much as Saint Thomas Aquinas thought of God. 1 As is well known, LudwigWittgenstein believed that there is something mysterious even about language itself, that basically what it is can be "shown" but not "said." 2 A certain tentativeness here in regard to propositional adequacy, I might add, is perfectly compatible with strong confidence in one's relation to what Wittgenstein called "the higher." 3 In regard to the truth to be found in the beliefs of others, even a megapandit such as Ken Wilber—not noted for his modesty and circumspection—observes that "the human mind is incapable of producing 100% error." 4 Perhaps some misunderstandings among those engaging in dialogue can be avoided if we remain mindful of the mysterious character of the subject matter and are less confident about the sufficiency of our own articulation of the truth.As to dialogue itself, it is perhaps well to remember when the issues of "fruit salad" and syncretism arise, 5 that thinking itself has typically a dialogical structure, with the result that "fruit salad" is actually the normal condition of persons as they develop in understanding themselves and their world. 6 In conversation with Laurence Freeman, O.S.B., the Dalai Lama appears to disapprove of mixing traditions—"Do not try to put a yak's head on a sheep's body" 7 —but it would be difficult to conceive of a more syncretistic religion than Tibetan Buddhism or Catholicism. Indeed, if we compare the early Jesus movement to the medieval church, the development of Catholicism might well be described by Luther or Calvin, had they thought of it, as an operation that put a yak's head on a sheep's body. The dialogical and finite structure of thinking is in fact one of the reasons why it is possible to conceive of a "universal religion," contrary to what the Dalai Lama thinks. 8 This is so because, since human understanding is never absolute and completed, there is always the possibility that future [End Page 101] understanding will yield a vision that embraces a multiplicity and diversity of religious insights in a way that is impossible for us to foresee at this time. Moreover, part of the point of American culture, I would think, is the benefits of mongrelization, and so perhaps Americans ought to be less suspicious than some at the thought of having "strange bedfellows." Looking for historical examples of conscious syncretism, one thinks of Mani and Jesuit syncretism exemplified in Matteo Ricci (outfitted first as a Buddhist monk and then later as a Confucian scholar) and the evangelization of New Spain, 9 and more recently, Hazrat Inayat Khan and his son, Pir Vilayat Khan. Also, there is Jesaiah Ben-Aharon, a Jewish thinker who interprets the Holocaust in terms of the Christ. 10 I find such efforts to be commendable, and so although doctrinal and cultural immaculacy has its charms, I believe it to be the call of maya. I will proceed, then, in constructing a mysterious and miscegenational fruit salad, my only justification being that this seems to reflect accurately the truth of the matter and that we really have no other peaceable choice. 11 Persons "Person" is often used in the same sense as "human being." By "person" I mean a being who can love and who, as a human being, is the... (shrink)

Brouwer's views on the foundations of mathematics have inspired the study of intuitionistic logic, including the study of the intuitionistic propositional calculus and its extensions. The theory of these systems has become an independent branch of logic with connections to lattice theory, topology, modal logic and other areas. This paper aims to present a modern account of semantics for intuitionistic propositional systems. The guiding idea is that of a hierarchy of semantics, organized by increasing generality: from the least general Kripke (...) semantics on through Beth semantics, topological semantics, Dragalin semantics, and finally to the most general algebraic semantics. While the Kripke, topological, and algebraic semantics have been extensively studied, the Beth and Dragalin semantics have received less attention. We bring Beth and Dragalin semantics to the fore, relating them to the concept of a nucleus from pointfree topology, which provides a unifying perspective on the semantic hierarchy. (shrink)

The standard topological representation of a Boolean algebra via the clopen sets of a Stone space requires a nonconstructive choice principle, equivalent to the Boolean Prime Ideal Theorem. In this article, we describe a choice-free topological representation of Boolean algebras. This representation uses a subclass of the spectral spaces that Stone used in his representation of distributive lattices via compact open sets. It also takes advantage of Tarski’s observation that the regular open sets of any topological space form a Boolean (...) algebra. We prove without choice principles that any Boolean algebra arises from a special spectral space X via the compact regular open sets of X; these sets may also be described as those that are both compact open in X and regular open in the upset topology of the specialization order of X, allowing one to apply to an arbitrary Boolean algebra simple reasoning about regular opens of a separative poset. Our representation is therefore a mix of Stone and Tarski, with the two connected by Vietoris: the relevant spectral spaces also arise as the hyperspace of nonempty closed sets of a Stone space endowed with the upper Vietoris topology. This connection makes clear the relation between our point-set topological approach to choice-free Stone duality, which may be called the hyperspace approach, and a point-free approach to choice-free Stone duality using Stone locales. Unlike Stone’s representation of Boolean algebras via Stone spaces, our choice-free topological representation of Boolean algebras does not show that every Boolean algebra can be represented as a field of sets; but like Stone’s representation, it provides the benefit of a topological perspective on Boolean algebras, only now without choice. In addition to representation, we establish a choice-free dual equivalence between the category of Boolean algebras with Boolean homomorphisms and a subcategory of the category of spectral spaces with spectral maps. We show how this duality can be used to prove some basic facts about Boolean algebras. (shrink)

More often than not, notes are conceptualized as a technology for helping students stay focused on and attentive to subject matter deemed educationally valuable. This article concerns itself, however, with how notes may interrupt and render inoperative this learning function. To probe the question of attention and distraction, the authors devised an experiment in note taking. Our question is whether or not these forms of rendering the learning function of notes inoperative have any educational value. In conclusion, we suggest that (...) such activities, while divorced from official, outcomes-based learning, do indeed have educational meaning: they make present the potentiality for thinking and acting without forcing such potentiality into measurable forms. What remains is the notes themselves, and the notational effects they in turn generated and continue to generate. (shrink)

Researchers consistently report that individuals see themselves acting far more ethically than comparable others when confronted with ethically uncertain work-related behaviors. They suggest that this belief encourages unethical conduct and contributes to the degeneration of business ethics; however, they have not specifically investigated the consequences of this belief. If undesirable work behaviors actually do occur, educators and other ethics advocates would be strongly encouraged to dispel this widely held notion.In the present study, data was collected from college students and practicing (...) accountants regarding how they and others would respond to ten ethical scenarios. Participants' perceptions were calculated and correlated to their decision in a hypothetical business case. Analysis indicated that individuals, regardless of age, gender, or work status, see themselves acting far more ethically than others. It also disclosed significant association between participants' own attitudes and the case response, but no significant association between the response and their attitudes relative to those perceived to be held by others. Believing that everyone else is less ethical, therefore, appears to have little impact on work behavior. (shrink)

The article contributes to debates about core executive capacity by analyzing the British and Japanese cases. First it examines the historical development, contemporary structures and current operations of the two cases. Then it compares their performance in five key areas: overseeing government policy in the domestic sphere; overseeing government policy in the external sphere; managing executive relations with the legislature; overseeing public finances; and managing public relations. It finds that the performance of the two systems is variable both internally across (...) distinct areas of business and, to a lesser extent, comparatively across similar areas. Overall, however, the British core executive is shown to have considerably greater capacity for coordinating and managing policy flows through the system than the Japanese. Governing from the centre is more feasible in Britain than in Japan. (shrink)

In this article, the author rethinks critiques of the learning society using Giorgio Agamben’s theory of potentiality. Summarizing several major contributions to our understanding of the limitations of the discourse of learning, the author proposes that critics thus far have failed to fully pinpoint the exact danger of learning. Importantly, learning is not only a rejection of the democratic or political dimension of education but it is first and foremost predicated on a false ontology of potentiality. What is put at (...) risk in learning is a sacrifice of our (im)potential, our capacity to be or not to be this or that within the order of things. Through a reconstruction of Agamben’s theory of studying, the author argues for a different conceptualization of freedom in education, of teaching, and of the time of education. (shrink)

This paper studies connections between two alternatives to the standard probability calculus for representing and reasoning about uncertainty: imprecise probability andcomparative probability. The goal is to identify complete logics for reasoning about uncertainty in a comparative probabilistic language whose semantics is given in terms of imprecise probability. Comparative probability operators are interpreted as quantifying over a set of probability measures. Modal and dynamic operators are added for reasoning about epistemic possibility and updating sets of probability measures.
