The idea that gauge theory has `surplus' structure poses a puzzle: in one much discussed sense, this structure is redundant; but on the other hand, it is also widely held to play an essential role in the theory. In this paper, we employ category-theoretic tools to illuminate an aspect of this puzzle. We precisify what is meant by `surplus' structure by means of functorial comparisons with equivalence classes of gauge fields, and then show that such (...) structure is essential for any theory that represents a rich collection of physically relevant fields which are `local' in nature.

We address a recent proposal concerning ‘surplus structure’ due to Nguyen et al.. We argue that the sense of ‘surplus structure’ captured by their formal criterion is importantly different from—and in a sense, opposite to—another sense of ‘surplus structure’ used by philosophers. We argue that minimizing structure in one sense is generally incompatible with minimizing structure in the other sense. We then show how these distinctions bear on Nguyen et al.’s arguments about (...) Yang-Mills theory and on the hole argument. (shrink)

It is a commonplace in the philosophy of physics that any local physical theory can be represented using arbitrary coordinates, simply by using tensor calculus. On the other hand, the physics literature often claims that spinors \emph{as such} cannot be represented in coordinates in a curved space-time. These commonplaces are inconsistent. What general covariance means for theories with fermions, such as electrons, is thus unclear. In fact both commonplaces are wrong. Though it is not widely known, Ogievetsky and Polubarinov constructed (...) spinors in coordinates in 1965, enhancing the unity of physics and helping to spawn particle physicists' concept of nonlinear group representations. Roughly and locally, these spinors resemble the orthonormal basis or "tetrad" formalism in the symmetric gauge, but they are conceptually self-sufficient and more economical. The typical tetrad formalism is de-Ockhamized, with six extra field components and six compensating gauge symmetries to cancel them out. The Ogievetsky-Polubarinov formalism, by contrast, is Ockhamized, with most of the fluff removed. As developed nonperturbatively by Bilyalov, it admits any coordinates at a point, but "time" must be listed first. Here "time" is defined in terms of an eigenvalue problem involving the metric components and the matrix $diag$, the product of which must have no negative eigenvalues in order to yield a real symmetric square root that is a function of the metric. Thus even formal general covariance requires reconsideration; the atlas of admissible coordinate charts should be sensitive to the types and \emph{values} of the fields involved. Apart from coordinate order and the usual spinorial two-valuedness, Ogievetsky-Polubarinov spinors form, with the metric, a nonlinear geometric object, for which important results on Lie and covariant differentiation are recalled. Such spinors avoid a spurious absolute object in the Anderson-Friedman analysis of substantive general covariance. They also permit the gauge-invariant localization of the infinite-component gravitational energy in General Relativity. Density-weighted spinors exploit the conformal invariance of the massless Dirac equation to show that the volume element is absent. Thus instead of an arbitrary nonsingular matrix with 16 components, 6 of which are gauged away by a new local $O$ gauge group and one of which is irrelevant due to conformal covariance, one can, and presumably should, use density-weighted Ogievetsky-Polubarinov spinors coupled to the 9-component symmetric square root of the part of the metric that fixes null cones. Thus $\frac{7}{16}$ of the orthonormal basis is eliminated as surplus structure. Greater unity between spinors and tensors and the like is achieved, such as regarding conservation laws. Regarding the conventionality of simultaneity, an unusually wide range of $\epsilon$ values is admissible, but some extreme values are inadmissible. Standard simultaneity uniquely makes the spinor transformation law linear and independent of the metric, because transformations among the standard Cartesian coordinate systems fall within the conformal group, for which the spinor transformation law is linear. The surprising mildness of the restrictions on coordinate order as applied to the Schwarzschild solution is exhibited. (shrink)

Although logical empiricism is now mostly decried, their naturalist claim that the content of a theory can be read off from its structure, without any philosophical considerations needed, still supports traditional strategies to escape cases of underdetermination. The appeal to theoretical equivalence or to theoretical virtues, for instance, both assume that there is a neutral standpoint from which the structure of the theories can be analyzed, the physically relevant from the superfluous separated, and a comparison made between their (...) theoretical content and virtues. In my dissertation, I examine the presuppositions upon which such strategies depend. I argue that the methodological principle underlying them, according to which theories with no superfluous structure should be preferred, is unpractical, for what constitutes relevant structure is determined by epistemic considerations about the aim of scientific theories. In chapter 1, I analyze the claim that theories with ordinary bosons and fermions are theoretically equivalent to theories with exotic `paraparticles'. I argue that this claim does not do justice to the latter, as the proof is formulated in a vocabulary parochial to the former and thus favors one of the theory while giving an impoverished version of the second. In chapter 2, I examine recent arguments to the effects that any interpretation of Quantum Mechanics that can offer a no-go theorem against paraparticles possesses an explanatory advantage over other interpretations and should, as such, be favored over others. Given that most physicists consider paraparticles as surplus structure whose non-observation does not require an explanation, I evaluate arguments of both sides and suggest a third way to approach the question. Finally, in chapter 3, I turn my attention to methods for excluding another kind of unphysical structure, mathematical artifacts, from rival dark matter models. Simulations are our only window into what rival models predict about the universe’s structure. But for them to play a useful role in generating knowledge, we need to distinguish reliably between real predictions and artifacts. I argue that robustness analysis fails to fulfill this task. I propose in its place another methodology, that of crucial simulations. (shrink)

Food charity in the United States has grown into a critical appendage of agro-food supply chains. In 2016, 4.5 billion pounds of food waste was diverted through a network of 200 regional food banks, a fivefold increase in just 20 years. Recent global trade disruptions and the COVID-19 pandemic have further reinforced this trend. Economic geographers studying charitable food networks argue that its infrastructure and moral substructure serve to revalue food waste and surplus labor in the capitalist food system. (...) The political–legal framework undergirding this revaluation process however is still poorly understood. Drawing on a 6-year institutional ethnography of the food banking economy in West Virginia, this paper takes a supply-side approach to examine the material and moral values driving the expansion of food waste recovery as hunger relief. Empirically, it focuses on the laws, contracts and fiscal incentives regulating charitable food procurement at the U.S. Department of Agriculture and Feeding America. The assemblage of government agencies, private businesses and non-profit organizations enrolled into this gift economy at different scales I argue, serves to enclose food waste into a public–private governance structure that regulates food surpluses and ensures these will not disrupt the scarcity logics driving profitability along primary food circuits.

This article analyses Achille Mbembe’s theorization of necropolitics and surplus life in dialogue with three comparable theorizations: Agamben’s ‘bare life’, Marxist scholarship on ‘relative surplus populations’, and Afropessimist theorizations of ‘social death’. I argue that Mbembe’s work allows us to develop a critique of sacrifice that at the same time (contra Agamben) recognizes how it plays a structural role within necropolitics. Examining the influence of Georges Bataille’s writings on sacrifice allows me to clarify this argument. The second part (...) of the article examines the ‘surplus life’ of necropolitics in comparative analysis, tracing some of the limits of Mbembe’s reading through a dialogue with Marxist and Afropessimist readings. I characterize Mbembe’s work in terms of a poetics and politics of surplus: ‘reserves of life’ are affirmed against the excess of violence characterizing the present. However, this critique of violence relies upon abrupt leaps from politics to abstract ethical appeals in ways that obscure the implications of Mbembe’s own analysis. (shrink)

We study a long-recognised but under-appreciated symmetry called dynamical similarity and illustrate its relevance to many important conceptual problems in fundamental physics. Dynamical similarities are general transformations of a system where the unit of Hamilton’s principal function is rescaled, and therefore represent a kind of dynamical scaling symmetry with formal properties that differ from many standard symmetries. To study this symmetry, we develop a general framework for symmetries that distinguishes the observable and surplus structures of a theory by using (...) the minimal freely specifiable initial data for the theory that is necessary to achieve empirical adequacy. This framework is then applied to well-studied examples including Galilean invariance and the symmetries of the Kepler problem. We find that our framework gives a precise dynamical criterion for identifying the observables of those systems, and that those observables agree with epistemic expectations. We then apply our framework to dynamical similarity. First we give a general definition of dynamical similarity. Then we show, with the help of some previous results, how the dynamics of our observables leads to singularity resolution and the emergence of an arrow of time in cosmology. (shrink)

The sources of embryos for Embryonic Stem Cell Research include surplus embryos from infertility treatments, and research embryos which are created solely for an ESCR purpose. The latter raises more ethical concerns. In a multi-religious country like Malaysia, ethical discussions on the permissibility of ESCR with regard to the use surplus and research embryos are diversified. Malaysia has formulated guidelines influenced by the national fatwa ruling which allows the use of surplus embryos in ESCR. Input from other (...) main religions is yet to be documented. In light of this, this study addresses the ethical viewpoints of Buddhist, Hindu and Catholic leaders on the permissibility of using surplus and research embryos; and the moral standpoints of religious leaders towards attaining a consensus on the practice of ESCR in Malaysia. Responses from the religious leaders were obtained via semi-structured, face-to-face interviews. The findings show that generally the Buddhist and Hindu leaders approve the use of surplus embryos. Their responses on the creation of research embryos for ESCR are varied. Meanwhile, the Catholic leaders distinctively objected to ESCR regardless of the embryo sources, referring to it as the destruction of life. Taking into account the diverse views, this study explores the response of the religious leaders for a general consensus wherever possible. The ethical discourse surrounding ESCR in a multi-religious setting offers new perspective, which needs to be explored in a broader global community. (shrink)

BackgroundHuman embryonic stem cells are currently used for developing treatment against Parkinson’s disease (PD). However, the use of ES cells is surrounded with moral concerns. Research regarding the public's attitudes can form an important basis for policymaking. The aim was to explore the perceptions of the public on using donated human embryos for developing treatment of Parkinson’s Disease.MethodsSemi-structured individual qualitative interviews were conducted with 11 members of the general population in Sweden. Interviews were analyzed with thematic content analyses.ResultsFour categories and (...) additional sub-categories; Different views on the embryo requires delicacy, Using embryos to treat Parkinson’s disease, Doing things in the right way, and Communication, media, and public opinion. In general, respondents were positive towards the usage of embryotic stem cells to treat PD, but the usage were conditioned and specific terms were demanded. Informed consent from both donors were required and delicacy and sensitivity when working with embryos were needed.ConclusionsIt was perceived better to use surplus embryos to treat PD increase is than to discard them, also among those who perceived the embryo as “a potential life.” The participants raised several conditions under usage for treatment should be allowed. Even if the embryos otherwise are going to be discarded, usage requires informed consent from the donating couples. (shrink)

Abstract.In Canada, food assistance is provided through a widespread network of extra-governmental, community-based, charitable programs, popularly termed “food banks”. Most of the food they distribute has been donated by food producers, processors, and retailers or collected through appeals to the public. Some industry donations are of market quality, but many donations are “surplus” food that cannot be retailed. Drawing on insights from an ethnographic study of food bank work in southern Ontario, we examined how the structure and function (...) of food banks operate to facilitate the distribution of foods not marketed through the retail system. Our findings indicate that the handling of industry donations of unsaleable products is a labor-intensive activity, made possible by the surfeit of unpaid labor in food banks, the neediness of food bank clients, and clients’ lack of rights in this system. The marshalling of volunteer labor to serve a corporate need might be construed as a “win-win” situation because the work of salvaging edible foodstuffs from among industry “surplus” helps to “feed the hungry” while also diminishing the amount of refuse deposited in landfill sites, sparing corporations disposal costs and landfill tipping fees, and helping them forge an image of good corporate citizenship. However, the reliance of food banks on industry donations means that food assistance becomes defined as that which the corporate sector cannot retail. Moreover, the intertwining of food bank work with corporate needs may function to further entrench this ad hoc secondary food system and mitigate against initiatives to develop more effective responses to problems of hunger and food insecurity in our communities.

In the seminar XVI, D'un Autre à l'autre, in 1968/1969, Jacques Lacan claimed that there is an homology between the function of object a in the unconscious and the Marxian notion of surplus-value. Both concepts in fact revolve around similar axes: their reluctance to be localized in a certain place of the structure and their connection with the notion of surplus. In Chapter 7 of Das Kapital, Marx seems to imagine a purely mythical pre-capitalist society where production (...) is only devoted the pure satisfaction of basic survival needs and where labour is still controlled by the worker according to a certain purpose: with the irruption of the surplus in the capitalist mode of production the very qualitative dimension of the production and reproduction of commodities and human beings is commanded and organized by the pure drive of abstract accumulation. In order to rearticulate the incessant capitalist drive for abstract wealth, the symptom relies on the unsurpassable contradiction between labour-power and living-labour: essential in order.

Jeffrey King, Scott Soames, and others have recently challenged the familiar identification of a Russellian proposition, such as the proposition that Brutus stabbed Caesar, with an ordered sequence constructed out of objects, properties, and relations. There is, as they point out, a surplus of candidate sequences available that are each equally serviceable. If so, any choice among these candidates will be arbitrary. In this paper, I show that, unless a controversial assumption is made regarding the nature of nonsymmetrical relations, (...) none of the proffered candidate sequences are in fact adequate to the play the role. Moreover, as I argue, the most promising alternative theory of relations—one that avoids the problematic assumption and, in addition, fits most naturally into the sequentialist’s framework—fails to meet a basic requirement: it cannot distinguish between the proposition that Brutus stabbed Caesar and the proposition that Caesar stabbed Brutus. The upshot is that the conspicuously structured entities that are widely assumed to be up to the task of “playing the proposition role” shed no light on the very structure they are invoked to represent.

In this paper I elicit a prediction from structural realism and compare it, not to a historical case, but to a contemporary scientific theory. If structural realism is correct, then we should expect physics to develop theories that fail to provide an ontology of the sort sought by traditional realists. If structure alone is responsible for instrumental success, we should expect surplus ontology to be eliminated. Quantum field theory (QFT) provides the framework for some of the best confirmed (...) theories in science, but debates over its ontology are vexed. Rather than taking a stand on these matters, the structural realist can embrace QFT as an example of just the kind of theory SR should lead us to expect. Yet, it is not clear that QFT meets the structuralist's positive expectation by providing a structure for the world. In particular, the problem of unitarily inequivalent representations threatens to undermine the possibility of QFT providing a unique structure for the world. In response to this problem, I suggest that the structuralist should endorse pluralism about structure. (shrink)

Various forms of underdetermination that might threaten the realist stance are examined. That which holds between different 'formulations' of a theory (such as the Hamiltonian and Lagrangian formulations of classical mechanics) is considered in some detail, as is the 'metaphysical' underdetermination invoked to support 'ontic structural realism'. The problematic roles of heuristic fruitfulness and surplus structure in attempts to break these forms of underdetermination are discussed and an approach emphasizing the relevant structural commonalities is defended.

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

How is that when scientists need some piece of mathematics through which to frame their theory, it is there to hand? What has been called 'the unreasonable effectiveness of mathematics' sets a challenge for philosophers. Some have responded to that challenge by arguing that mathematics is essentially anthropocentric in character, whereas others have pointed to the range of structures that mathematics offers. Otavio Bueno and Steven French offer a middle way, which focuses on the moves that have to be made (...) in both the mathematics and the relevant physics in order to bring the two into appropriate relation. This relation can be captured via the inferential conception of the applicability of mathematics, which is formulated in terms of immersion, inference, and interpretation. In particular, the roles of idealisations and of surplus structure in science and mathematics respectively are brought to the fore and captured via an approach to models and theories that emphasize the partiality of the available information: the partial structures approach. The discussion as a whole is grounded in a number of case studies drawn from the history of quantum physics, and extended to contest recent claims that the explanatory role of certain mathematical structures in scientific practice supports a realist attitude towards them. The overall conclusion is that the effectiveness of mathematics does not seem unreasonable at all once close attention is paid to how it is actually applied in practice. (shrink)

The widely held picture of dynamical symmetry as surplus structure in a physical theory has many metaphysical applications. Here, I focus on its relevance to the question of which quantities in a theory represent fundamental natural properties.

Suppose that one thinks that certain symmetries of a theory reveal “surplus structure”. What would a formalism without that surplus structure look like? The conventional answer is that it would be a reduced theory: a theory which traffics only in structures invariant under the relevant symmetry. In this paper, I argue that there is a neglected alternative: one can work with a sophisticated version of the theory, in which the symmetries act as isomorphisms.

In this article, I give a counterexample to a claim made in that empirically equivalent theories can often be regarded as theoretically equivalent by treating one as having surplus structure, thereby overcoming the problem of underdetermination of theory choice. The case I present is that of Lorentz's ether theory and Einstein's theory of special relativity. I argue that Norton's suggestion that surplus structure is present in Lorentz's theory in the form of the ether state of rest (...) is based on a misunderstanding of the role that the ether plays in Lorentz's theory, and that in general, consideration of the conceptual framework in which a theory is embedded is vital to understanding the relationship between different theories.

Some physicists and philosophers argue that unitarily inequivalent representations in quantum field theory are mathematical surplus structure. Support for that view, sometimes called ‘algebraic imperialism’, relies on Fell’s theorem and its deployment in the algebraic approach to QFT. The algebraic imperialist uses Fell’s theorem to argue that UIRs are ‘physically equivalent’ to each other. The mathematical, conceptual, and dynamical aspects of Fell’s theorem will be examined. Its use as a criterion for physical equivalence is examined in detail and (...) it is proven that Fell’s theorem does not apply to the vast number of representations used in the algebraic approach. UIRs are not another case of theoretical underdetermination, because they make different predictions about ‘classical’ operators. These results are applied to the Unruh effect where there is a continuum of UIRs to which Fell’s theorem does not apply. _1_ Introduction _2_ Weak Equivalence and Physical Equivalence _3_ Mathematical Overview of Algebraic Quantum Field Theory _4_ Fell’s Theorem and Philosophical Responses to Weak Equivalence _5_ Weak Equivalence in C*-Algebras and W*-Algebras _6_ Classical Equivalence and Weak Equivalence _7_ Interlude: Is Weak Equivalence Really Physical Equivalence? _8_ The Unruh Effect _9_ Time Evolution and Symmetries _10_ Conclusions Appendix.

The idea of “two discoveries” in Marx is essentially known through the presentations of Engels and Stalin, which had lasting influences in the constitution of “Marxism”. They essentially insisted on a correlation of “theories” or “disciplines” hierarchically articulated . But it had another, earlier and more specific, formulation offered by Marx himself, when trying to emphasize the novelty of his theory in Capital, Volume One. Marx singled out, on the one side, the “double character of labour” expressed in the value-form, (...) on the other side the articulation of “surplus labour” and “surplus value”. In this essay, we attempt a thought experiment which considers the “two discoveries” claimed by Marx not as successive moments of a single demonstration, also not as falling apart in an “epistemological break”, but as terms of a “disjunctive synthesis”. It would subject the critique of capitalism to a permanent tension, with, on one side, the logic of universal commodification arising from the institution of the General Equivalent, and on the other, the comparative study of modes of exploitation and domination in different “class structures”. The resulting ambiguities in the formulation of the “communist hypothesis” in Marx are perhaps of no little import in today’s renewed interest for the Marxian critique. (shrink)

Marx's rethinking of the combination between absolute surplus-value and relative surplus-value during the 1860s is very important in order to reconsider the co-presence of different forms of historical temporality and exploitation. Postmodernism presents a picture of a plurality of historical times in which the old lies beside the modern and the sweatshop beside the high-tech factory. Because it fails to provide an explanation of the relation between these forms, postmodernism produces a false image of an 'ahistorical' present. In (...) this article I want to show how the combination of differentials of surplus-value works and why a representation of a plurality of historical temporalities synchronised by the temporality of socially-necessary labour is the most adequate image to comprehend it. The theoretical task is to show how the mature categorial structure of Capital not only does not need an historicist philosophy of history, but is in fact incompatible with it. (shrink)

Grey zone attacks tend to paralyze response for two reasons. First, they present us with choice scenarios of inherently dilemmatic structure, e.g., Prisoners’ Dilemmas and games of chicken, complicated by difficult conditions of choice, such as choice under risk or amid vagueness. Second, they exploit our uncertainty about how much we do or should care about the things under attack¬—each attack is small in effect, but their effects accumulate: how should we decide whether to treat a given attack as (...) something meriting a serious response rather than a mere irritation to be ignored? This chapter brings standard decision theoretic tools to bear on the issues, tools such as the maximization of expected utility principle, and the precautionary principle. But it also develops three innovations. It shows that seeing it as possible to make choices not just of actions given our values, but also choices of values themselves, can extricate us from certain kinds of decision paralysis. It shows how we can rationally regard ourselves as having bright decision lines even when nothing in the circumstance of choice has these lines in its structure. And it shows how certain conflict escalation risks from the former two strategies can be managed by both parties seeing that cooperation can yield a sharable surplus of goods, and that cooperation can be rational upon a rationally defensible change in their values so that each comes to derive utility from the success of both parties. This yields cooperative solutions to what amount to Prisoners’ Dilemmas. The Cold War was prosecuted on the logic of strategic rationality and that part of game theory that is deterrence theory. We need a new logic from decision theorists for the games that constitute grey zone conflict. (shrink)

Next SectionObjective The purpose of this article is to investigate the need for ethics support in Dutch healthcare institutions in order to understand why ethics support is often not used in practice and which factors are relevant in this context. Methods This study had a mixed methods design integrating quantitative and qualitative research methods. Two survey questionnaires, two focus groups and 17 interviews were conducted among board members and ethics support staff in Dutch healthcare institutions. Findings Most respondents see a (...) need for ethics support. This need is related to the complexity of contemporary healthcare, the contribution of ethics support to the core business of the organisation and to the surplus value of paying structural attention to ethical issues. The need for ethics support is, however, not unconditional. Reasons for a lacking need include: aversion of innovations, negative associations with the notion of ethics support service, and organisational factors like resources and setting. Conclusion There is a conditioned need for ethics support in Dutch healthcare institutions. The promotion of ethics support in healthcare can be fostered by focusing on formats which fit the needs of (practitioners in) healthcare institutions. The emphasis should be on creating a (culture of) dialogue about the complex situations which emerge daily in contemporary healthcare practice. (shrink)

This paper presents a simple mathematical model that shows how economic inequality between social groups can arise and be maintained even when the only adaptive learning process driving cultural evolution increases individuals’ economic gains. The key assumptions are that human populations are structured into groups and that cultural learning is more likely to occur within than between groups. Then, if groups are sufficiently isolated and there are potential gains from specialization and exchange, stable stratification can sometimes result. This model predicts (...) that stratification is favored, ceteris paribus, by (1) greater surplus production, (2) more equitable divisions of the surplus among specialists, (3) greater cultural isolation among subpopulations within a society, and (4) more weight given to economic success by cultural learners.

Anger gaslighting is behavior that tends to make someone doubt herself about her anger. In this paper, I analyze the case of anger gaslighting, using it as a paradigm case to argue that gaslighting can be an affective injustice (not only an epistemic one). Drawing on Marilyn Frye, I introduce the concept of “uptake” as a tool for identifying anger gaslighting behavior (persistent, pervasive uptake refusal for apt anger). But I also demonstrate the larger significance of uptake in the study (...) of affective injustice: just as the concept of credibility names the epistemic behavior whereby we take someone seriously as an epistemic being, the concept of uptake names the uniquely affective cooperative behavior whereby we take someone seriously as an affective being. I answer Miranda Fricker’s epistemic notion of a prejudicial credibility economy with the affective notion of prejudicial uptake economies: uptake, like credibility, can be produced in a deficit for one social group relative to a surplus for another. Deviating from the parallels with Fricker, for whom the injustice of epistemic injustice is due to prejudice in the motives or character of individuals, as well as from accounts that ground it in aptness or affective goods, I suggest that the injustice of anger gaslighting behavior can be located at the structural scale of power relationships between social groups, in the tradition of Iris Marion Young. Anger gaslighting behavior counts as unjust wherever it (re)produces prejudicial uptake economies. Adapting sociological concepts of feeling rules and the emotion work they demand, I introduce the concepts of “uptake rules” and “uptake work” to further enable analysis of uptake economies as affective social structures, and to suggest a site for resistant or reparative affective agency.

Sustainability assessments bring together different perspectives that pertain to sustainability in order to produce overall assessments and a wealth of approaches and tools have been developed in the past decades. But two major problematics remain. The problem of integration concerns the surplus of possibilities for integration; different tools produce different assessments. The problem of implementation concerns the barrier between assessment and transformation; assessments do not lead to the expected changes in practice. This paper aims to analyze issues of complementarity (...) in sustainability assessment and transformation as a key to better handling the problems of integration and implementation. Based on a generalization of Niels Bohr’s complementarity from quantum mechanics, we have identified two forms of complementarity in sustainability assessment, observer stance complementarity and value complementarity. Unlike many other problems of sustainability assessment, complementarity is of a fundamental character connected to the very conditions for observation. Therefore complementarity cannot be overcome methodologically; only handled better or worse. Science is essential to the societal goal of sustainability, but these issues of complementarity impede the constructive role of science in the transition to more sustainable structures and practices in food systems. The agencies of sustainability assessment and transformation need to be acutely aware of the importance of different perspectives and values and the complementarities that may be connected to these differences. An improved understanding of complementarity can help to better recognize and handle issues of complementarity. These deliberations have relevance not only for sustainability assessment, but more generally for transdisciplinary research on wicked problems. (shrink)

This chapter sets forth a general theory of gender stratification. While both biological and ideological variables are taken into account, the emphasis is structural: It is proposed that the major independent variable affecting sexual inequality is each sex's economic power, understood as relative control over the means of production and allocation of surplus. For women, relative economic power is seen as varying-and not always in the same direction-at a variety of micro- and macrolevels, ranging from the household to the (...) state. A series of propositions links the antecedents of women's relative economic power, the interrelationship between economic and other forms of power, and the forms of privilege and opportunity into which each gender can translate its relative power.

I provide a fairly systematic analysis of when quantities that are variant under a dynamical symmetry transformation should be regarded as unobservable, or redundant, or unreal; of when models related by a dynamical symmetry transformation represent the same state of affairs; and of when mathematical structure that is variant under a dynamical symmetry transformation should be regarded as surplus. In most of these cases the answer is `it depends': depends, that is, on the details of the symmetry in (...) question. A central feature of the analysis is that in order to draw any of these conclusions for a dynamical symmetry it needs to be understood in terms of its possible extensions to other physical systems, in particular to measurement devices.

This paper is a report of an empirical psychological study of the relationship between the ethical and financial beliefs and desires of ethical investors. Semi-structured interviews of 20 ethical investors have been carried out by the project 10 of which have been analysed using qualitative data analysis software. All of our participants faced the problem that, while they had ethical concerns, they were not prepared to sacrifice their essential financial requirements to address them. We found four common ways of dealing (...) with this problem: they divided up their money into core and surplus accounts; they decided that it was enough to only be a partial ethical investor; they avoided detailed consideration of the costs of ethical investment; and they avoided rigorous ethical thinking. One equilibrium position arising from these responses is a portfolio approach to ethics, which allows people to assuage their consciences by investing only a small proportion of their investments ethically, while leaving the rest in non-ethical investment vehicles.

This dissertation contextualizes the emergence of the Church of Light by Tadao Ando within the Japanese religio-philosophical tradition of nothingness. The idea of nothingness was revived during the first half of the twentieth-century by Kitaro Nishida with two cultural ramifications in the post-war period: a series of dialogues on the points of convergence and divergence between nothingness and the God of Christianity, and an architectural art movement called Monoha, or l'Ecole de Choses. Under the concept of "structuring emptiness," Monoha attempted (...) to restore perceptual depth where dichotomous semiotic representation is overcome through shintaisei, the co-originating corporeal fabric between the subject and object. This two-fold mapping, theological and architectural, not only illuminates the post-war cultural milieu from which Ando's church of spatial emptiness emerged, but also locates the church within the legacy of Nishida's nothingness. ;Nishida's philosophy of nothingness offers a perceptual theory of the "dialectic of self-negation" enacted by shintai, "the actively knowing body." Shintai is the agent of emptying selfhood by functioning as 'the sensational capacity to be filled by' the world. Shintai concretizes the perceptual matrix of co-emergence between the interiority of selfhood and the outside world. When its sensational capacity overflows, shintai enters into the realm of creative action to accommodate the surplus. The figure thus created is not a sign embodying subjective intentions, but constitutes the corporelly-inscribed, pre-reflective experiential datum of the world. Nishida called such a figure "the pure body of the artist," implying its apprehension not as the other in unknowable confrontation, but as the extended self. ;The dissertation examines how this notion of self-renunciatory perception through shintai opens a new hermeneutic horizon for the Church of Light. The church presents an unprecedented conjunction between emptiness, based on the reductive removal of signs, and the cross of light. This seemingly contradictory integration confronts the modern degradation of the cross into an atrophied sign of Christianity and seeks to retrieve its fully efficacious symbolic power. The emptiness contributes to the revival of a deeper communicative mode as shintai by negating the habituated perception pivoted upon the dichotomy between the deciphering subject and the semiotic elements. The perception of light, a natural thing rather than a sign, which infiltrates the cross, is a preliminary ritual to save the perception from the paradigm of the semiotic representation. Shintai, the self-emptying corporeality, resonates with and becomes penetrated by, rather than subjectivizes, the light. On this restored perceptual depth, the cross is perceived not as a sign, but as a part of the pre-reflective, ontological datum constructed and apprehended by shintai. This perceptual experience endorses the associational similarity between the pre-Christian datum predicated upon shintai as the agent of the self-renunciatory subjectivity and Christianity with its theology of the self-transcending love of kenosis.

This paper presents a variable-free analysis of relational nouns in Glue Semantics, within a Lexical Functional Grammar (LFG) architecture. Relational nouns and resumptive pronouns are bound using the usual binding mechanisms of LFG. Special attention is paid to the bound readings of relational nouns, how these interact with genitives and obliques, and their behaviour with respect to scope, crossover and reconstruction. I consider a puzzle that arises regarding relational nouns and resumptive pronouns, given that relational nouns can have bound readings (...) and resumptive pronouns are just a specific instance of bound pronouns. The puzzle is why is it impossible for bound implicit arguments of relational nouns to be resumptive? The puzzle is highlighted by a well-known variety of variable-free semantics, where pronouns and relational noun phrases are identical both in category and (base) type. I show that the puzzle also arises for an established variable-based theory. I present an analysis of resumptive pronouns that crucially treats resumptives in terms of the resource logic linear logic that underlies Glue Semantics: a resumptive pronoun is a perfectly ordinary pronoun that constitutes a surplus resource; this surplus resource requires the presence of a resumptive-licensing resource consumer, a manager resource. Manager resources properly distinguish between resumptive pronouns and bound relational nouns based on differences between them at the level of semantic structure. The resumptive puzzle is thus solved. The paper closes by considering the solution in light of the hypothesis of direct compositionality. It is argued that a directly compositional version of the theory is possible, although perhaps not desirable. The implications for direct compositionality are considered. (shrink)

At a time when some modicum of formal gender equality has been won in many late‐capitalist societies of the West, what explains the persistence of practices that extract labor and value from women and girls while granting a “surplus” of value to men and boys? Gendered shame is a central mechanism of the apparatus that secures the continued subordination of women across a number of class and race contexts in the mediatized, late‐capitalist West. Focusing on the story of Amanda (...) Todd, two forms of shame are distinguished. “Ubiquitous shame” is that shame that accrues to feminine existence as such, and is structured in relation to a futural temporality of redemption. “Unbounded shame” is a brute form of value‐extraction that has found its ecological niche in social media—and destroys all futural aspirations.

Marx conceives of capitalism as a production mode based on the exploitation of labour-power, whose productive consumption in the labour process is considered as the main source of value creation. Capitalists seek to obscure and secure workers’ contribution to the production process, whereas workers strive to have their contribution fully recognized. The struggle between capitalists and workers over labour-time is thus central to capital’s valorization process. Hence, capital–labour antagonism is structured over the capture and exploitation of unpaid labour-time. Building on (...) Marx’s labour value theory, as well as on some of its contemporary interpretations, I call this struggle over labour-time capture a process of ‘invisibilization’ of labour. I claim that this invisibilization process is still a relevant form of surplus-value extraction in contemporary capitalism, especially in the platform economy, characterized by remote but pervasive control by algorithms. The rediscovery of this form of surplus-value extraction and its manifestation in platform labour is the main contribution of this study. To corroborate this contribution, I compare the case of platform labour with that of textile-clothing, where value production is more clearly based on the classical forms of surplus-value extraction (i.e., absolute and relative). This comparison helps to cast a new light on the nexus between work-process transformations and surplus-value creation, which is the core of the Marxian labour theory of value, and which – I argue – is crucial to understanding contemporary capitalist developments.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Buddhisms and DeconstructionsFrancis X. Clooney, SJBuddhisms and Deconstructions. Edited by Jin Y. Park, with an afterword by Robert Magliola. Lanham, MD: Rowman & Littlefield Publishers, Inc., 2006. Pp. xxii + 290.Buddhisms and Deconstructions originated in a panel on "Buddhism, Deconstruction, and the Works of Robert Magliola" at the twenty-second annual convention [End Page 182] of the International Association for Philosophy and Literature. Half its essays began as conference (...) papers, while the rest (including several published elsewhere) were solicited for the volume. Implicit too are an awareness of other volumes—for example, Harold Coward's Derrida and Indian Philosophy (1990) and (with Toby Foshay) Derrida and Negative Theology (1992)—and the conviction that such volumes, although making a contribution, have not adequately sorted out what can usefully be said with respect to that tantalizingly elusive couple, deconstruction and Buddhism.The volume exemplifies many starting points and avenues for testing the Buddhism-deconstruction relationship, but all of it is clearly mapped. "Buddhism and Deconstruction" (section 1) illumines some basic issues underlying Buddhist-deconstructionist comparisons: "Naming the Unnameable: Dependent Co-arising and Différence" (Jin Y. Park) and "Nagarjuna and Deconstruction" (Ian Mabbett). "Buddhism Deconstructs" (section 2) explores how deconstruction can be analyzed from a Buddhist perspective, and includes "Derridean and Madhyamika Buddhist Theories of Deconstruction" (Zong-qi Cai) and "Indra's Postmodern Net" (David R. Loy). "Deconstructing Buddhism" (section 3), with essays on "Deconstructive and Foundationalist Tendencies in Indian and Tibetan Buddhism" (Roger R. Jackson) and "Ji Zang's Sunyata-Speech: Derridean Denegation with Buddhist Negations" (Ellen Y. Zhang), looks in the other direction, still further deconstructing Buddhism. "Chan/Zen Buddhist Deconstruction" (section 4) furthers the critique with another pair of detailed analyses, "The Chan Deconstruction of Buddha Nature" (Youru Wang) and "Sudao: Repeating the Question in Chan Discourse" (Frank W. Stevenson). All these authors stick with cases in order to test the larger Buddhism and deconstruction hypothesis, showing, unsurprisingly, that similarities and differences make comparisons work out in different ways and for different conclusions. It matters which Buddhist tradition is brought into play, how one interprets some particular Buddhist thinker, and (because almost everyone here is thinking of "Derrida" and "deconstruction" at the same time) how someone with Buddhist learning ought to read which early or late essay by Derrida. Altogether, these eight essays illumine specific examples and contribute to the volume's larger topic, as we narrow down and define the Budhism-Deconstructionism conversation. Loy perhaps speaks for many of the authors here:From a Buddhist perspective, the post-structural realization that the meaning of a text cannot be totalized—that language/thought never attains a self-presence which escapes differences—is an important step towards the realization that there is no abiding-place for the mind anywhere within Indra's net. But the textual dissemination liberated by Derrida's deconstruction will not be satisfactory unless the dualist sense-of-self—not just its discourse—has been deconstructed.(p. 80)Or, as Ellen Zhang soberly puts it, [End Page 183]The play of sunyata/denegation implies a movement of thought that sees the surplus of thought, and understanding this surplus sometimes requires the un-thought. The moment of negativity is, therefore, also the moment of construction and creativity. Sunyata/denegation is not simply a nihilistic place of reducing meaning to non-meaning, reality to non-reality. On the contrary, it is the moment of emancipation of meanings, we find in the Chinese traditions from Zhuangzi to Buddhist philosophers and Chan masters. Meanwhile, the experiential dimensions in the process of transforming our thought and consciousness explored by Daoism and Buddhism also offer a possible critique of postmodern discourse.(p. 121)One could well imagine an entire volume made of just these essays with just such insights.But there is more. In "Deconstructing Life-Worlds" (section 5), two essays—"The Veil Rent in Twain: A Buddhist Reading of Robert Magliola's Deconstructive Chiasm" (Jane Augustine) and "Emmanuel, Robert" (Gad Horowitz)—remind us that the volume is indeed a still more complex three-way conversation, including also the writings and personality (evident by the vehicle of an Afterword) of Robert Magliola, a scholar of both Buddhism (which he teaches...
