The context of economic globalization has contributed to the emergence of a new form of social action which has spread into the economic sphere in the form of the new social economic movements. The emblematic figure of this new generation of social movements is fair trade, which influences the economy towards political or social ends. Having emerged from multiple alternative trade practices, fair trade has gradually become institutionalized since the professionalization of World Shops, the arrival of fair trade products in (...) the food industry, and the establishment of an official "fair trade" label. With the strength that this institutionalization has generated, fair trade can now be considered a real trade system that questions, as much as it renews, the traditional economic system. In parallel, this transformation has exacerbated the tensions within the movement, which can be characterized as a clash between a "radical, militant" pole and a "softer, more commercial" one. However, it is not the actual institutionalization of fair trade which is being debated among fair trade actors on either side of the fence, but rather the challenges inherent in finding an economic institutionalization acceptable to social economic movements. Therefore the institutionalization process of fair trade should not be seen as mere degradation of social action, but rather as typical of the institutionalization process of new social economic movements. If we need to worry about the highjacking and alteration of the fair trade movement by the dominant economic system, the opposite is no less likely, as new social economic movements contribute to an ethical restructuring of markets.

El aumento en la producción y consumo de frutas y hortalizas mínimamente procesadas de los últimos años ha con­tribuido a incrementar las toxiinfecciones alimentarias asociadas al consumo de productos vegetales frescos. Esto es debido a que los tratamientos desinfectantes llevados a cabo actualmente por industria de IV gama son insuficientes para garantizar la seguridad microbiológica de los productos finales, y además estos no reciben ningún tratamiento capaz de eliminar todos los patógenos antes de su consumo. Por lo tanto, es necesario (...) utilizar estrategias al­ternativas para reducir los microorganismos patógenos y alteran­tes en frutas y hortalizas. La bioconservación, mediante el uso de microorganismos o sus metabolitos, es una alternativa que, en combinación con las prácticas habituales, puede reducir o prevenir el crecimiento de patógenos en productos mínimamente procesa­dos, mejorando su calidad microbiológica. En este artículo se pre­sentan los resultados más relevantes sobre la bioconservación de frutas y hortalizas mínimamente procesadas. (shrink)

La industria de alimentos vegetales consume grandes volúmenes de agua de buena calidad y genera grandes cantida­des de agua residual. Uno de los sistemas que se pueden aplicar para reducir el consumo y el vertido de agua es la reutilización del agua de lavado. Para llevar a cabo la reutilización del agua sin comprometer la seguridad microbiológica y química de los alimentos es necesario optimizar el uso de agentes antimicrobia­nos. El cloro ha sido tradicionalmente el tratamiento de desinfec­ción usado por (...) la industria hortofrutícola para el agua de lavado. Sin embargo, su uso tiene la desventaja de la acumulación de subproductos de desinfección, lo que ha impulsado el estudio y el uso de desinfectantes alternativos como el ácido peroxiacéti­co. En cualquier caso, el mantenimiento de la seguridad micro­biológica y química de los alimentos vegetales frescos, en lo que respecta a la etapa de lavado, pasa por la selección de los límites operacionales que deben mantenerse en cuanto a la concentra­ción de desinfectante, así como la monitorización y control de los parámetros críticos relacionados con la desinfección, como es el contenido en materia orgánica. La optimización de la desinfec­ción tiene que tener en cuenta las peculiaridades de cada caso, incluyendo el tipo de producto lavado, el desinfectante usado, y el diseño y manejo de la línea de lavado.

The relationship between students and higher education is seen to have become increasingly transactional. We approach the study of the student–HE relationship in a novel way, by focusing on students’ behaviour post-university, rather than on student narratives. Conceptually, the article builds on multidimensional views of student engagement and the differentiation between psychological transactional contracts – where students who achieve better academic results are more likely to donate – and relational contracts – where students donate more following engagement in social experiences. (...) Making use of longitudinal data on donation behaviour from over 50,000 alumni from an English university over two decades, we find that while students who get better degree outcomes are more likely to donate, the association between participation in social experiences and donations is much stronger. This questions prevalent transactional models of HE and underlines the limitations of purely consumerist views of the relation between students and higher education institutions, even in the marketized UK context.

Is the mathematical function being computed by a given physical system determined by the system’s dynamics? This question is at the heart of the indeterminacy of computation phenomenon (Fresco et al. [unpublished]). A paradigmatic example is a conventional electrical AND-gate that is often said to compute conjunction, but it can just as well be used to compute disjunction. Despite the pervasiveness of this phenomenon in physical computational systems, it has been discussed in the philosophical literature only indirectly, mostly with (...) reference to the debate over realism about physical computation and computationalism. A welcome exception is Dewhurst’s ([2018]) recent analysis of computational individuation under the mechanistic framework. He rejects the idea of appealing to semantic properties for determining the computational identity of a physical system. But Dewhurst seems to be too quick to pay the price of giving up the notion of computational equivalence. We aim to show that the mechanist need not pay this price. The mechanistic framework can, in principle, preserve the idea of computational equivalence even between two different enough kinds of physical systems, say, electrical and hydraulic ones. (shrink)

Do the dynamics of a physical system determine what function the system computes? Except in special cases, the answer is no: it is often indeterminate what function a given physical system computes. Accordingly, care should be taken when the question ‘What does a particular neuronal system do?’ is answered by hypothesising that the system computes a particular function. The phenomenon of the indeterminacy of computation has important implications for the development of computational explanations of biological systems. Additionally, the phenomenon lends (...) some support to the idea that a single neuronal structure may perform multiple cognitive functions, each subserved by a different computation. We provide an overarching conceptual framework in order to further the philosophical debate on the nature of computational indeterminacy and computational explanation. (shrink)

There are many different notions of information in logic, epistemology, psychology, biology and cognitive science, which are employed differently in each discipline, often with little overlap. Since our interest here is in biological processes and organisms, we develop a taxonomy of functional information that extends the standard cue/signal distinction. Three general, main claims are advanced here. This new taxonomy can be useful in describing learning and communication. It avoids some problems that the natural/non-natural information distinction faces. Functional information is​ ​produced (...) through exploration and stabilisation processes. (shrink)

Artefacts do not always do what they are supposed to, due to a variety of reasons, including manufacturing problems, poor maintenance, and normal wear-and-tear. Since software is an artefact, it should be subject to malfunctioning in the same sense in which other artefacts can malfunction. Yet, whether software is on a par with other artefacts when it comes to malfunctioning crucially depends on the abstraction used in the analysis. We distinguish between “negative” and “positive” notions of malfunction. A negative malfunction, (...) or dysfunction, occurs when an artefact token either does not or cannot do what it is supposed to. A positive malfunction, or misfunction, occurs when an artefact token may do what is supposed to but, at least occasionally, it also yields some unintended and undesirable effects. We argue that software, understood as type, may misfunction in some limited sense, but cannot dysfunction. Accordingly, one should distinguish software from other technical artefacts, in view of their design that makes dysfunction impossible for the former, while possible for the latter. (shrink)

The phenomenon of digital computation is explained (often differently) in computer science, computer engineering and more broadly in cognitive science. Although the semantics and implications of malfunctions have received attention in the philosophy of biology and philosophy of technology, errors in computational systems remain of interest only to computer science. Miscomputation has not gotten the philosophical attention it deserves. Our paper fills this gap by offering a taxonomy of miscomputations. This taxonomy is underpinned by a conceptual analysis of the design (...) and implementation of conventional computational systems at various levels of abstraction. It shows that ‘malfunction’ as it is typically used in the philosophy of artefacts only represents one type of miscomputation. (shrink)

This paper deals with the question: how is computation best individuated? -/- 1. The semantic view of computation: computation is best individuated by its semantic properties. 2. The causal view of computation: computation is best individuated by its causal properties. 3. The functional view of computation: computation is best individuated by its functional properties. -/- Some scientific theories explain the capacities of brains by appealing to computations that they supposedly perform. The reason for that is usually that computation is individuated (...) semantically. I criticize the reasons in support of this view and its presupposition of representation and semantics. Furthermore, I argue that the only justified appeal to a representational individuation of computation might be that it is partly individuated by implicit intrinsic representations. (shrink)

A single physical process may often be described equally well as computing several different mathematical functions—none of which is explanatorily privileged. How, then, should the computational identity of a physical system be determined? Some computational mechanists hold that computation is individuated only by either narrow physical or functional properties. Even if some individuative role is attributed to environmental factors, it is rather limited. The computational semanticist holds that computation is individuated, at least in part, by semantic properties. She claims that (...) the mechanistic account lacks the resources to individuate the computations performed by some systems, thereby leaving interesting cases of computational indeterminacy unaddressed. This article examines some of these views, and claims that more cases of computational indeterminacy can be addressed, if the system-environment interaction plays a greater role in individuating computations. A new, long-arm functional strategy for individuating computation is advanced. (shrink)

The question ‘What is computation?’ might seem a trivial one to many, but this is far from being in consensus in philosophy of mind, cognitive science and even in physics. The lack of consensus leads to some interesting, yet contentious, claims, such as that cognition or even the universe is computational. Some have argued, though, that computation is a subjective phenomenon: whether or not a physical system is computational, and if so, which computation it performs, is entirely a matter of (...) an observer choosing to view it as such. According to one view, which we dub bold anti-realist pancomputationalism, every physical object computes every computer program. According to another, more modest view, some computational systems can be ascribed multiple computational descriptions. We argue that the first view is misguided, and that the second view need not entail observer-relativity of computation. At least to a large extent, computation is an objective phenomenon. Construed as a form of information processing, we argue that information-processing considerations determine what type of computation takes place in physical systems. (shrink)

Mentioning products or brands on Facebook enables individuals to display an ideal self to others through a form of virtual conspicuous consumption. Drawing on conspicuous donation behaviour literature, we investigate ‘conspicuous virtue signalling’, as conspicuous consumption on Facebook. CVS occurs when an individual mentions a charity on their Facebook profile. We investigate need for uniqueness and attention to social comparison information as antecedents of two types of CVS–self-oriented and other-oriented. We also explore the relationship between CVS and self-esteem, and offline (...) prosocial and unethical behaviour intentions. Data from two studies, a college survey and an adult survey via MTurk, were analysed using structural equation modelling. Results indicate that NFU predicts both forms of CVS, while ATSCI influences both forms of CVS for adults and other-oriented CVS for students. Self-esteem is enhanced by self-oriented CVS. Self-oriented CVS predicts donation intention whereas other-oriented CVS significantly reduces donation intention for both samples. Furthermore, a significant relationship between CVS and purchase intention of counterfeit luxury goods is revealed. Findings provide insights into conspicuous virtue signalling and the relationship between CVS on Facebook and offline behavioural intentions. (shrink)

Hume argued that inductive inferences do not have rational justification. My aim is to reject Hume's argument. The discussion is partly motivated by an analogy with Carroll's Paradox, which concerns deductive inferences. A first radically externalist reply to Hume is that justified inductive inferences do not require the subject to know that nature is uniform, though the uniformity of nature is necessary condition for having the justification. But then the subject does not have reasons for believing what she believes. I (...) defend a moderate externalist account that seeks to partly accommodate that objection to the radical externalist proposal. It is based on an extension of Peacocke's theory of concepts: possession conditions for predicative concepts standing for natural properties include dispositions to project them to new cases in accordance with inductive inferential patterns.

As intergenerational interactions increase due to an ageing population, the study of emotion-related responses to the elderly is increasingly relevant. Previous research found mixed results regarding affective mimicry – a measure related to liking and affiliation. In the current study, we investigated emotional mimicry to younger and older actors following an encounter with a younger and older player in a Cyberball game. In a complete exclusion condition, in which both younger and older players excluded the participant, we expected emotional mimicry (...) to be stronger for younger vs. older actors. In a partial inclusion condition, in which the younger player excluded while the older player included the participant, we predicted that the difference in player behaviour would lead to a difference in liking. This increased liking of the older interaction partner should reduce the difference in emotional mimicry towards the two different age groups. Results revealed more mimicry for older actors following partial inclusion especially for negative emotions, suggesting inclusive behaviour by an older person in an interaction as a possible means to increase mimicry and affiliation to the elderly.

We describe the role of morphosyntactic categories and syntactic dependencies in the process of semantically interpreting composite expressions. Special attention will be paid to the combinatorial properties conveyed by morphosyntactic categories such as nominals and verbs, as well as by syntactic dependencies like subject, direct object, or nominal modification. The semantic characterisation of these grammatical structures is based on cognitive abilities and abstract conceptualisations. This will provide us with theoretical arguments to review and extend some basic assumptions of Cognitive Grammar (...) and related work. (shrink)

It is often indeterminate what function a given computational system computes. This phenomenon has been referred to as “computational indeterminacy” or “multiplicity of computations.” In this paper, we argue that what has typically been considered and referred to as the challenge of computational indeterminacy in fact subsumes two distinct phenomena, which are typically bundled together and should be teased apart. One kind of indeterminacy concerns a functional characterization of the system’s relevant behavior. Another kind concerns the manner in which the (...) abstract states are interpreted. We discuss the similarities and differences between the two kinds of computational indeterminacy, their implications for certain accounts of “computational individuation” in the literature, and their relevance to different levels of description within the computational system. We also examine the inter-relationships between our proposed accounts of the two kinds of indeterminacy and the main accounts of “computational implementation.”. (shrink)

The claims that “The brain processes information” or “Cognition is information processing” are accepted as truisms in cognitive science. However, it is unclear how to evaluate such claims absent a specification of “information” as it is used by neurocognitive theories. The aim of this article is, thus, to identify the key features of information that information-based neurocognitive theories posit. A systematic identification of these features can reveal the explanatory role that information plays in specific neurocognitive theories, and can, therefore, be (...) both theoretically and practically important. These features can be used, in turn, as desiderata against which candidate theories of information may be evaluated. After discussing some characteristics of explanation in cognitive science and their implications for “information”, three notions are briefly introduced: natural, sensory, and endogenous information. Subsequently, six desiderata are identified and defended based on cognitive scientific practices. The global workspace theory of consciousness is then used as a specific case study that arguably posits either five or six corresponding features of information. (shrink)

Which notion of computation (if any) is essential for explaining cognition? Five answers to this question are discussed in the paper. (1) The classicist answer: symbolic (digital) computation is required for explaining cognition; (2) The broad digital computationalist answer: digital computation broadly construed is required for explaining cognition; (3) The connectionist answer: sub-symbolic computation is required for explaining cognition; (4) The computational neuroscientist answer: neural computation (that, strictly, is neither digital nor analogue) is required for explaining cognition; (5) The extreme (...) dynamicist answer: computation is not required for explaining cognition. The first four answers are only accurate to a first approximation. But the “devil” is in the details. The last answer cashes in on the parenthetical “if any” in the question above. The classicist argues that cognition is symbolic computation. But digital computationalism need not be equated with classicism. Indeed, computationalism can, in principle, range from digital (and analogue) computationalism through (the weaker thesis of) generic computationalism to (the even weaker thesis of) digital (or analogue) pancomputationalism. Connectionism, which has traditionally been criticised by classicists for being non-computational, can be plausibly construed as being either analogue or digital computationalism (depending on the type of connectionist networks used). Computational neuroscience invokes the notion of neural computation that may (possibly) be interpreted as a sui generis type of computation. The extreme dynamicist argues that the time has come for a post-computational cognitive science. This paper is an attempt to shed some light on this debate by examining various conceptions and misconceptions of (particularly digital) computation. (shrink)

There has been an ongoing conflict regarding whether reality is fundamentally digital or analogue. Recently, Floridi has argued that this dichotomy is misapplied. For any attempt to analyse noumenal reality independently of any level of abstraction at which the analysis is conducted is mistaken. In the pars destruens of this paper, we argue that Floridi does not establish that it is only levels of abstraction that are analogue or digital, rather than noumenal reality. In the pars construens of this paper, (...) we reject a classification of noumenal reality as a deterministic discrete computational system. We show, based on considerations from classical physics, why a deterministic computational view of the universe faces problems (e.g., a reversible computational universe cannot be strictly deterministic).

What is nontrivial digital computation? It is the processing of discrete data through discrete state transitions in accordance with finite instructional information. The motivation for our account is that many previous attempts to answer this question are inadequate, and also that this account accords with the common intuition that digital computation is a type of information processing. We use the notion of reachability in a graph to defend this characterization in memory-based systems and underscore the importance of instructional information for (...) digital computation. We argue that our account evaluates positively against adequacy criteria for accounts of computation. (shrink)

It is common in cognitive science to equate computation (and in particular digital computation) with information processing. Yet, it is hard to find a comprehensive explicit account of concrete digital computation in information processing terms. An information processing account seems like a natural candidate to explain digital computation. But when ‘information’ comes under scrutiny, this account becomes a less obvious candidate. Four interpretations of information are examined here as the basis for an information processing account of digital computation, namely Shannon (...) information, algorithmic information, factual information and instructional information. I argue that any plausible account of concrete computation has to be capable of explaining at least the three key algorithmic notions of input, output and procedures. Whist algorithmic information fares better than Shannon information, the most plausible candidate for an information processing account is instructional information. (shrink)

In the wake of the 2008 global financial crisis, an important conceptual battleground for democratic theorists ought to be, it would seem, the capitalist firm. We are now painfully aware that the typical model of government in so-called investor-owned companies remains profoundly oligarchic, hierarchical, and unequal. Renewing with the literature of the 1970s and 1980s on workplace democracy, a few political theorists have started to advocate democratic reforms of the workplace by relying on an analogy between firm and state. To (...) the extent that a firm is an organization comparable to the state, it too ought to be ruled along democratic lines. Our paper tests the robustness of the analogy between firm and state by considering six major objections to it: the objection from a difference in ends, the objection from shareholders’ property rights, the objection from worker’s consent, the objection from workers’ exit opportunities, the objection from workers’ expertise, and the objection from the fragility of firms. We find all of these objections wanting. While the paper does not ambition to settle the issue of workplace democracy at once, our goal is to pave the way for a more in-depth study of the ways in which firms and states can be compared and the possible implications this may have for our understanding of the nature of managerial authority and the governance of firms.

Empiricist philosophers like Carnap invoked analyticity in order to explain a priori knowledge and necessary truth. Analyticity was “truth purely in virtue of meaning”. The view had a deflationary motivation: in Carnap’s proposal, linguistic conventions alone determine the truth of analytic sentences, and thus there is no mystery in our knowing their truth a priori, or in their necessary truth; for they are, as it were, truths of our own making. Let us call this “Carnapian conventionalism”, conventionalismC and cognates for (...) short. This conventionalistC explication of the a priori has been the target of sound criticisms. Arguments like Quine’s in “Truth by Convention” are in our view decisive: the truth of conventionalismC requires that the class of logical truths and logical validities be reductively accounted for as conventionally established; however, no such reduction is forthcoming, because logic is needed to generate the entire class from any given set of conventions properly so-called. Granted that conventionalismC is untenable, we want to take issue with a different, usually made criticism. Although the argument uncovers some difficulties for the way conventionalist claims are defended by some of its advocates, we will try to show that it fails. The criticism thus stands in the way of a proper appreciation of why the Carnapian account of the a priori is not correct. We will try to illustrate this by showing that the criticism we will dispute would dispose of conventionalist claims not only regarding philosophically problematic cases – logical and mathematical truths –, but also regarding cases for which they have some prima facie plausibility. One such case is that of truths that follow from mere abbreviations, “nominal” definitions; ‘someone is a bachelor if and only if he is an unmarried adult male’ can serve at this point for illustration. We will try to articulate a clear sense in which the contents of assertion such as this can be truths by convention. We do not need to prove that a conventionalist claim is true in those cases; it is enough for us to show that it is intelligible, for the arguments we will confront question even this. (shrink)
