A prevailing focus of global value chain (GVC) analysis has been on the dominance of highly consolidated Northern retailers over suppliers in the global South. The rise of regional and domestic value chains (RVCs/DVCs) within the Global South which intersect with GVCs, has been found to involve private governance by Southern lead firms. However, we have limited insight into the implications of this changing value chain context for the role of public governance, or different groups of workers. South African fruit (...) provides a rich example of rapid shifts in RVCs/DVCs governed by different private and public actors. The following two questions are addressed: How is the public–private governance of labour standards evolving in the context of RVCs and DVCs that intersect with GVCs? What are the implications for workers operating across different value chains? Conceptually, the paper draws on GVC analysis of governance and power, to examine the governance of labour standards across intersecting value chains. Our analysis highlights the intentional and unintentional mechanisms through which power and standard-setting are diffused away from Northern lead firms to a wider array of public and private actors operating across RVCs/DVCs. While existing analysis of governance and power focuses on singular GVCs, our study highlights diffusion of power across intersecting value chains, with significant and uneven implications for the public–private governance of labour standards. Our findings carry significant ethical implications for the governance of labour standards, as end-markets continue to shift South. (shrink)

This paper is concerned with the logical structure of arithmetical theories. We survey results concerning logics and admissible rules of constructive arithmetical theories. We prove a new theorem: the admissible propositional rules of Heyting Arithmetic are the same as the admissible propositional rules of Intuitionistic Propositional Logic. We provide some further insights concerning predicate logical admissible rules for arithmetical theories.

In this paper we describe a framework for the construction of entities that can serve as interpretations of arbitrary contiguous chunks of text. An important part of the paper is devoted to describing stacking cells, or the proposed meanings for bracket-structures.

In this paper we examine various requirements on the formalisation choices under which self-reference can be adequately formalised in arithmetic. In particular, we study self-referential numberings, which immediately provide a strong notion of self-reference even for expressively weak languages. The results of this paper suggest that the question whether truly self-referential reasoning can be formalised in arithmetic is more sensitive to the underlying coding apparatus than usually believed. As a case study, we show how this sensitivity affects the formal study (...) of certain principles of self-referential truth. (shrink)

In this sequel toSelf-reference in arithmetic Iwe continue our discussion of the question: What does it mean for a sentence of arithmetic to ascribe to itself a property? We investigate how the properties of the supposedly self-referential sentences depend on the chosen coding, the formulae expressing the properties and the way a fixed point for the expressing formulae are obtained. In this second part we look at some further examples. In particular, we study sentences apparently expressing their Rosser-provability, their own${\rm{\Sigma (...) }}_n^0$-truth or their own${\rm{\Pi }}_n^0$-truth. Finally we offer an assessment of the results of both papers. (shrink)

Over the past decade land has again moved to the centre of resource conflicts, agrarian struggles, and competing visions over the future of food and farming. This renewed interest in land necessitates asking the seemingly simple, but pertinent, question ‘whatisland?’ To reach a more profound understanding of the uniqueness of land, and what distinguishes land from other resources, this symposium suggests the notion of ‘land imaginaries’ as a crucial lens in the study of current land transformations. Political-economy, and the particular (...) economic, financial, or political interests of various actors involved in land projects do not directly result in, or translate into, outcomes, such as dispossession and enclosure, increased commodification, financialization, and assetization, or mobilization and resistance. All these processes are informed by different imaginaries of land—the underlying understandings, views, and visions of what land is, can, and should be—and associated visions, hopes, and dreams regarding land. Drawing on a variety of case studies from across the world, crossing Global North/South and East/West, and including contemporary and historical instances of land transformation, this symposium addresses the multifaceted ways in which implicit, explicit, and emergent understandings of land shape current land transformations.

In this paper, we study finitely axiomatizable conservative extensions of a theoryUin the case whereUis recursively enumerable and not finitely axiomatizable. Stanisław Krajewski posed the question whether there are minimal conservative extensions of this sort. We answer this question negatively.Consider a finite expansion of the signature ofUthat contains at least one predicate symbol of arity ≥ 2. We show that, for any finite extensionαofUin the expanded language that is conservative overU, there is a conservative extensionβofUin the expanded language, such that$\alpha (...) \vdash \beta$and$\beta \not \vdash \alpha$. The result is preserved when we consider eitherextensionsormodel-conservative extensionsofUinstead ofconservative extensions. Moreover, the result is preserved when we replace$\dashv$as ordering on the finitely axiomatized extensions in the expanded language by a relevant kind of interpretability, to witinterpretability that identically translates the symbols of the U-language.We show that the result fails when we consider an expansion with only unary predicate symbols for conservative extensions ofUordered by interpretability that preserves the symbols ofU.

In this note we compare propositional logics for closed substitutions and propositional logics for open substitutions in constructive arithmetical theories. We provide a strong example where these logics diverge in an essential way. We prove that for Markov's Arithmetic, that is, Heyting's Arithmetic plus Markov's principle plus Extended Church's Thesis, the logic of closed and the logic of open substitutions are the same.

In this paper, we show that the predicate logics of consistent extensions of Heyting's Arithmetic plus Church's Thesis with uniqueness condition are complete $\Pi _{2}^{0}$. Similarly, we show that the predicate logic of HA*, i.e. Heyting's Arithmetic plus the Completeness Principle (for HA*) is complete $\Pi _{2}^{0}$. These results extend the known results due to Valery Plisko. To prove the results we adapt Plisko's method to use Tennenbaum's Theorem to prove 'categoricity of interpretations' under certain assumptions.

This article critically evaluates the possible impact of the Charter on the relationship between the Court of Justice of the European Union and national constitutional courts. While it is premature to provide a definitive assessment of the kind of collaboration that these courts will develop, it is crucial to identify a number of features of the new landscape that will influence the direction in which the relationship between the CJEU and constitutional courts will evolve. This article discusses several reasons that (...) may result in better or a higher number of judicial interactions, as well as factors that may create tension or cause problems in the relationship between the CJEU and national constitutional courts. As such, it offers a framework that may help us to understand future post-Charter judgments by these courts setting out how they conceive their engagement with their counterpart on fundamental rights issues.

With direct-to-consumer advertisements (DTCA), pharmaceutical companies can market their prescription drugs directly to consumers. In order to properly study the argumentative aspect of these advertisements from a pragma-dialectical perspective, it is necessary to characterize DTCA as an ‘argumentative activity type’. This characterization shows that in DTCA, the advertiser combines two genres of communicative activity: promotion and consultation. The use of promotion stems from the advertiser’s commercial objective of selling products, while the use of consultation is a result of the legal (...) obligation to present a fair balance between arguments for and against the use of a drug.

There is a “Pragmatist turn” visible in the field of organization science today, resulting from a renewed interest in the work of Pragmatist philosophers like Dewey, Mead, Peirce, James and others, and in its implications for the study of organizations. Following Wicks and Freeman, in the past decade Pragmatism has also entered the field of business ethics, which, however, has not been uniformly applauded in that field. Some scholars fear that Pragmatism may enhance already existing positivist and managerialist tendencies in (...) current business ethics, while others see more emancipatory potential in Pragmatism, arguing that it complements and supports stakeholder theory. In this paper, a comparison of the philosophical underpinnings of Pragmatist and Critical conceptions of business ethics is offered, concentrating on the Pragmatism of John Dewey and the Critical theory of the Frankfurt School, in particular of Axel Honneth. It is argued that these two developed along two converging lines. Along the first line, Dewey was far more skeptical and critical of capitalism than is often thought. Along the second line, the reactions to Pragmatism of Frankfurt School Critical theorists developed over time from generally hostile, to partially inclusive, to more fully integrative. At the crossroads of these converging lines a Pragmatist Critical perspective is developed and exemplified, and its implications for business ethics are outlined. (shrink)

A good place to start in assessing a theory of truth is to ask whether the theory under discussion is consistent with Aristotle’s commonsensical definition of truth from Metaphysics 4: “What is false says of that which is that it is not, or of that which is not that it is; and what is true says of that which is that it is, or of that which is not that it is not.”1 Philosophers of a realist bent will be delighted (...) to see that Anselm unambiguously adopts the Aristotelian commonplace. A statement is true, he says, “when it signifies that what‐is is.”2 But the theory of truth that Anselm builds on this observation is one that would surely have confounded Aristotle. For no matter what the topic, Anselm’s thinking always eagerly returns to God; and the unchallenged centrality of God in Anselm’s philosophical explorations is nowhere more in evidence than in his account of truth. Indeed, we see in the student’s opening question in De veritate that the entire discussion has God as its origin and its aim: “Since we believe that God is truth, and we say that truth is in many other things, I would like to know whether, wherever truth is said to be, we must acknowledge that God is that truth.”3 The student then reminds Anselm that in the Monologion he had argued from the truth of statements to an eternal Supreme Truth. Does this not commit Anselm (the student seems to be asking) to holding that God himself is somehow the truth of true statements? But what definition of truth could make sense of such an odd claim? Anselm is happy to take up the challenge of showing that his description of God as “Supreme Truth” is no mere metaphor, but the expression of the deepest insight into the nature of truth. An account of truth is just theology under a different name. This first distinctive characteristic of Anselm’s theory, the centrality of God as Supreme Truth, helps account for a second distinctive characteristic: its strong insistence on the unity of truth. All truth either is God or somehow reflects God; thus, one simple being provides the.... (shrink)

In this paper we offer a reconstruction of Anselm’s account of freedom that resolves various apparent inconsistencies. The linchpin of this account is the definition of freedom. Anselm argues that the power to preserve rectitude for its own sake requires the power to initiate an action of which the agent is the ultimate cause, but it does not always require that alternative possibilities be available to the agent. So while freedom is incompatible with coercion and external causal determination, an agent (...) can, under certain circumstances, act freely even though he cannot act otherwise than he does.

A possible way out of the conundrum of quantum gravity is the proposal that general relativity (GR) emerges from an underlying microscopic description. Despite recent interest in the emergent gravity program within the physics as well as the philosophy community, an assessment of the general motivation for this idea is lacking at the moment. We intend to fill this gap in the literature by discussing the main arguments in favour of the hypothesis that the metric field and its dynamics are (...) emergent. First, we distinguish between microstructure inspired from GR, such as through quantization or discretization, and microstructure that is not directly motivated from GR, such as strings, quantum bits or condensed matter fields. The emergent gravity approach can then be defined as the view that the metric field and its dynamics are derivable from the latter type of microstructure. Subsequently, we assess in how far the following properties of (semi-classical) GR are suggestive of underlying microstructure: (1) the metric's universal coupling to matter fields, (2) perturbative non-renormalizability, (3) black hole thermodynamics, and (4) the holographic principle. In the conclusion we formalize the general structure of the plausibility arguments put forward. (shrink)

This paper contains a careful derivation of principles of Interpretability Logic valid in extensions of I0+1.

In this paper, we characterize the strength of the predicative Frege hierarchy, , introduced by John Burgess in his book [J. Burgess, Fixing frege, in: Princeton Monographs in Philosophy, Princeton University Press, Princeton, 2005]. We show that and are mutually interpretable. It follows that is mutually interpretable with Q. This fact was proved earlier by Mihai Ganea in [M. Ganea, Burgess’ PV is Robinson’s Q, The Journal of Symbolic Logic 72 619–624] using a different proof. Another consequence of the our (...) main result is that is mutually interpretable with Kalmar Arithmetic . The fact that interprets EA was proved earlier by Burgess. We provide a different proof. Each of the theories is finitely axiomatizable. Our main result implies that the whole hierarchy taken together, , is not finitely axiomatizable. What is more: no theory that is mutually locally interpretable with is finitely axiomatizable. (shrink)

We show that a consistent, finitely axiomatized, sequential theory cannot prove its own inconsistency on every definable cut. A corollary is that there are at least three degrees of global interpretability of theories equivalent modulo local interpretability to a consistent, finitely axiomatized, sequential theory U.

In this paper we study the idea of theories with containers, like sets, pairs, sequences. We provide a modest framework to study such theories. We prove two concrete results. First, we show that first-order theories of finite signature that have functional non-surjective ordered pairing are definitionally equivalent to extensions in the same language of the basic theory of non-surjective ordered pairing. Second, we show that a first-order theory of finite signature is sequential (is a theory of sequences) iff it is (...) definitionally equivalent to an extension in the same language of a system of weak set theory called WS.

This article critically analyzes the assumption that land is becoming increasingly scarce and that, therefore, farmland values are bound to rise across the globe. It investigates the process of land value creation, as well as its flipside: value erosion and stagnation, looking at the various mechanisms involved in each. As such, it is a study of how the financialization of agriculture affects the process of land commoditization. I show that, for farmland to be turned into an asset, a whole range (...) of conditions have to be fulfilled, presenting a typology of asset making in the context of farmland. Asset making, like commoditization, is a process of assemblage, and it is less straightforward and less stable than generally assumed. Further, I argue that ‘asset making’ is not a one-way process. The article is based on an analysis of global data on land values and the case of farmland investment in post-Soviet farmland. (shrink)

In this article, we want to reply to the recent article by Buturovic, to be able to correct some statements and allegations about this combined procedure. Organ donation after euthanasia is an extremely difficult procedure from an ethical point of view. On the one hand, we see a suffering patient who wants to die but who also wants to make an altruistic effort to donate his organs. On the other hand, we visualise a patient in need of an organ but (...) who is wary of the fact that someone else needs to die in order to potentially receive a transplant organ. Healthcare professionals seem to walk a tightrope when balancing between the interests of the patients at these two extremes: while facilitating the dying patient’s last wish on the one hand and abiding by all regulations regarding donation and transplantation on the other. Yet, these physicians, nurses and transplant coordinators do their utmost best to keep a strict line between euthanasia and organ donation, to avoid any external pressure on the patient, and to respect his autonomy. They really make an utmost attempt to make the process bearable for the donating patient. However, undeniably the patient who is about to undergo organ donation after euthanasia is nevertheless confronted with dozens of feelings and thoughts. However, this does not imply that procedural safeguards are failing to disentangle organ donation from euthanasia. (shrink)

This paper is concerned with notions of consequence. On the one hand, we study admissible consequence, specifically for substitutions of Σ 1 0 -sentences over Heyting arithmetic . On the other hand, we study preservativity relations. The notion of preservativity of sentences over a given theory is a dual of the notion of conservativity of formulas over a given theory. We show that admissible consequence for Σ 1 0 -substitutions over HA coincides with NNIL -preservativity over intuitionistic propositional logic . (...) Here NNIL is the class of propositional formulas with no nestings of implications to the left . The identical embedding of IPC -derivability into a consequence relation has in many cases a left adjoint. The main tool of the present paper will be an algorithm to compute this left adjoint in the case of NNIL -preservativity. In the last section, we employ the methods developed in the paper to give a characterization the closed fragment of the provability logic of HA. (shrink)

According to Anselm's official definition, freedom of choice is ‘the power to preserve rectitude of will for the sake of that rectitude itself.’ From the point of view of contemporary metaphysics, this is one of the most unhelpful definitions imaginable. Does such freedom require alternative possibilities, for example? Is it compatible with causal determination? Is the exercise of such freedom a necessary and sufficient condition for moral responsibility? The definition sheds no light on these questions.And so we need to move (...) on from Anselm's definition to Anselm's account of freedom. Here, though, we encounter the opposite problem. Where Anselm's definition seems not to answer these questions at all, Anselm's account seems to answer all these questions, sometimes with a yes and sometimes with a no. Consider the question about alternative possibilities. In De libertate arbitrii, Anselm seems clearly to deny that freedom involves alternative possibilities. God, the good angels, and the blessed dead cannot do otherwise than preserve rectitude, but they are still free- freer, in fact, than those who are capable of abandoning rectitude. (shrink)

In this paper we study local induction w.r.t. Σ1‐formulas over the weak arithmetic. The local induction scheme, which was introduced in, says roughly this: for any virtual class that is progressive, i.e., is closed under zero and successor, and for any non‐empty virtual class that is definable by a Σ1‐formula without parameters, the intersection of and is non‐empty. In other words, we have, for all Σ1‐sentences S, that S implies, whenever is progressive. Since, in the weak context, we have (at (...) least) two definitions of Σ1, we obtain two minimal theories of local induction w.r.t. Σ1‐formulas, which we call Peano Corto and Peano Basso.In the paper we give careful definitions of Peano Corto and Peano Basso. We establish their naturalness both by giving a model theoretic characterization and by providing an equivalent formulation in terms of a sentential reflection scheme.The theories Peano Corto and Peano Basso occupy a salient place among the sequential theories on the boundary between weak and strong theories. They bring together a powerful collection of principles that is locally interpretable in. Moreover, they have an important role as examples of various phenomena in the metamathematics of arithmetical (and, more generally, sequential) theories. We illustrate this by studying their behavior w.r.t. interpretability, model interpretability and local interpretability. In many ways the theories are more like Peano arithmetic or Zermelo Fraenkel set theory, than like finitely axiomatized theories as Elementary Arithmetic, and. On the one hand, Peano Corto and Peano Basso are very weak: they are locally cut‐interpretable in. On the other hand, they behave as if they were strong: they are not contained in any consistent finitely axiomatized arithmetical theory, however strong. Moreover, they extend, the theory of parameter‐free Π1‐induction. (shrink)

The rise of the platform economy in the past two decades (and neoliberal capitalist expansion and crises more in general), have on the whole negatively affected working conditions, leading to growing concerns about the “human side” of organizations. To address these concerns, the purpose of this paper is to apply Axel Honneth’s recognition theory and method of normative reconstruction to working conditions in the platform economy. The paper concludes that the ways in which platform organizations function constitutes a normative paradox, (...) promising flexibility and autonomy while at the same time creating working conditions that undercut these promises. The paper ends with a critical discussion of Honneth’s approach, possible supplementing ideas and further lines of future research. (shrink)

A Kripke model ? is a submodel of another Kripke model ℳ if ? is obtained by restricting the set of nodes of ℳ. In this paper we show that the class of formulas of Intuitionistic Predicate Logic that is preserved under taking submodels of Kripke models is precisely the class of semipositive formulas. This result is an analogue of the Łoś-Tarski theorem for the Classical Predicate Calculus.In Appendix A we prove that for theories with decidable identity we can take (...) as the embeddings between domains in Kripke models of the theory, the identical embeddings. This is a well known fact, but we know of no correct proof in the literature. In Appendix B we answer, negatively, a question posed by Sam Buss: whether there is a classical theory T, such that ℋT is HA. Here ℋT is the theory of all Kripke models ℳ such that the structures assigned to the nodes of ℳ all satisfy T in the sense of classical model theory. (shrink)

The central result of this paper is the small‐is‐very‐small principle for restricted sequential theories. The principle says roughly that whenever the given theory shows that a definable property has a small witness, i.e., a witness in a sufficiently small definable cut, then it shows that the property has a very small witness: i.e., a witness below a given standard number. Which cuts are sufficiently small will depend on the complexity of the formula defining the property. We draw various consequences from (...) the central result. E.g., roughly speaking, (i) every restricted, recursively enumerable sequential theory has a finitely axiomatized extension that is conservative with respect to formulas of complexity ; (ii) every sequential model has, for any n, an extension that is elementary for formulas of complexity, in which the intersection of all definable cuts is the natural numbers; (iii) we have reflection for ‐sentences with sufficiently small witness in any consistent restricted theory U; (iv) suppose U is recursively enumerable and sequential. Suppose further that every recursively enumerable and sequential V that locally inteprets U, globally interprets U. Then, U is mutually globally interpretable with a finitely axiomatized sequential theory. The paper contains some careful groundwork developing partial satisfaction predicates in sequential theories for the complexity measure depth of quantifier alternations. (shrink)

This article looks at how imaginaries of land and climate play a role in farmland investment discourses and practices. Foreign farmland investors in the fertile black earth region of Russia and Ukraine have ‘celebrated’ soil fertility while largely ignoring climatic factors. The article shows a centuries-long history of outsiders coming to the region lured by the fertile soils, while grossly underestimating climate which has had disastrous implications for farm viability and the environment. Comparisons with historical and contemporary literature on other (...) regions suggest that the underestimation of climatic risks by newcomers is remarkably prevalent in resource frontiers. (shrink)
