Using properties of${\cal K}$-pairs of sets, we show that every nonzero enumeration degreeabounds a nontrivial initial segment of enumeration degrees whose nonzero elements have all the same jump asa. Some consequences of this fact are derived, that hold in the local structure of the enumeration degrees, including: There is an initial segment of enumeration degrees, whose nonzero elements are all high; there is a nonsplitting high enumeration degree; every noncappable enumeration degree is high; every nonzero low enumeration degree can be (...) capped by degrees of any possible local jump ; every enumeration degree that bounds a nonzero element of strictly smaller jump, is bounding; every low enumeration degree below a non low enumeration degreeacan be capped belowa.

The jump operator on the ω-enumeration degrees was introduced in [I.N. Soskov, The ω-enumeration degrees, J. Logic Computat. 17 1193–1214]. In the present paper we prove a jump inversion theorem which allows us to show that the enumeration degrees are first order definable in the structure of the ω-enumeration degrees augmented by the jump operator. Further on we show that the groups of the automorphisms of and of the enumeration degrees are isomorphic. In the second part of the paper we (...) study the jumps of the ω-enumeration degrees below . We define the ideal of the almost zero degrees and obtain a natural characterization of the class H of the ω-enumeration degrees below which are high n for some n and of the class L of the ω-enumeration degrees below which are low n for some n.

We show that the theory of the local structure of the enumeration degrees is computably isomorphic to the theory of first order arithmetic. We introduce a novel coding method, using the notion of a K-pair, to code a large class of countable relations.

We give several new characterizations of the continuous enumeration degrees. The main one proves that an enumeration degree is continuous if and only if it is not half a nontrivial relativized K-pair. This leads to a structural dichotomy in the enumeration degrees.

We show that every splitting of ${0}_{\mathrm{e}}^{\prime }$ in the local structure of the enumeration degrees, $$\mathcal{G}_{e} , contains at least one low-cuppable member. We apply this new structural property to show that the classes of all $\mathcal{K}$ -pairs in $\mathcal{G}_{e}$ , all downwards properly ${\mathrm{\Sigma }}_{2}^{0}$ enumeration degrees and all upwards properly ${\mathrm{\Sigma }}_{2}^{0}$ enumeration degrees are first order definable in $\mathcal{G}_{e}$.

The paper focuses on the difference between event‐conditionals and premise‐conditionals. An event‐conditional contributes to event structure: it modifies the main clause event; a premise‐conditional structures the discourse: it makes manifest a proposition that is the privileged context for the processing of the associated clause. The two types of conditional clauses will be shown to differ both in terms of their ‘external syntax’ and in terms of their ‘internal syntax’. The peripheral structure of event conditionals will be shown to lack the (...) functional head Force, which encodes illocutionary force. Event conditionals are merged inside the IP of the matrix clause. Premise‐conditionals contain the head Force and they are merged outside the associated CP. (shrink)

Michel Henry wishes to salvage Descartes’s first principle ‘I think, I am’ by claiming that there is no need to appeal to the world or others to make sense of the self. One of his main targets is Edmund Husserl, who claims that thought is necessarily intentional and thus necessarily about something that is other to thought. To show that this is not so, Henry draws on passages from Descartes’s texts which emphasize that we should not equate the cogito with (...) thinking but with sensation and imagination. This allows Henry to explore the notion that the self has its own form of manifestation. This paper questions Henry’s reading of Descartes and his critique of Husserl on two fronts. First, the passages Henry draws upon, if anything only confirm, rather than question Husserl’s claim that consciousness is intentional. Second, Henry believes that he can show that the life of the self is infinitely rich without having to appeal to other persons or, indeed, to the world. Yet, I wish to contend that Henry is mistaken: as Husserl has shown convincingly, a life without others and the world is not only impoverished and bereft of meaning, but remains entirely indeterminate. The self only manifests itself with respect to others and the world. (shrink)

This paper discusses corporate entanglement, impactfulness and responsibility in the Anthropocene, amidst events and conditions that ‘uncontain’ time. It takes its direction of travel from artist Brian Jungen’s ‘Cetology’ (2002), a whalebone sculpture made out of cut-up plastic garden chairs, which conjoins the times of earth and world history, as it hangs in the air of the art gallery, ‘as if’ exhibited in the natural history museum. The paper relates ‘Cetology’s’ engagement with natural history, time, and commodification to matters of (...) corporate entanglement and responsibility within company law and governance. Problems with understanding the comparable imprint of large and multinational companies on matters, places, and communities are identified, after the domination of corporate legal frameworks over nature and the stability and perfection of economic incentives at law. The reading of this (critical-legal) situation is developed through theory and engagement with materialist and critical thinkers, who unite in their concern with distributed human–nature relations and the ‘concreteness’ that attends collisions in time, ruin and affect. Walter Benjamin and Theodor Adorno’s writings are central to this analysis, and strengthen the commentary on ‘natural history’ themes curated by Jungen. The paper contemplates how times’ uncontainment might invoke a change in expectation and method for the company law field, assigning contingency to the corporation and provoking a new mode of reflection about corporate entanglement and responsibility at law.

The ability to sequence individual genomes is leading to the identification of an increasing number of genetic risk factors for serious diseases. Knowledge of these risk factors can often provide significant medical and psychological benefit, but also raises complex ethical and social issues. This paper focuses on one area of rapid progress: the identification of mutations causing long QT syndrome and other cardiac channel disorders, which can explain some previously unexplained deaths in infants (SIDS) and children and adults (SUDS) and (...) prevent others from occurring. This genetic knowledge, discovered posthumously in many cases, has implications for clinical care for surviving family members who might carry the same mutations. The information obtained from genetic testing, in the context of personal and family history, can guide individually tailored interventions that reduce risk and save lives. At the same time, obtaining and disclosing genetic information raises difficult issues about confidentiality and decision making within families. We draw on the experience of the Montefiore-Einstein Center for Cardiogenetics, which has played a leading role in the genetic diagnosis and clinical management of cardiac channel diseases, to explore some of the challenging ethical questions arising in affected families with adolescent children. We focus on the related issues of (1) family confidentiality, privacy and disclosure and (2) adolescent decision making about genetic risk, and argue for the value of interdisciplinary dialogue with affected families in resolving these issues.

Michel Serres’s philosophy of entropy takes what he famously calls the ‘Northwest Passage’ between the sciences and the humanities. By contextualizing his approach to entropy and affirming the role of a philosophy of difference, this paper explores Serres’s approach by means of ‘entropic differences’. It claims that entropy – or rather, entropies – provide Serres with a paradigmatic case for critical translations between different domains of knowledge. From his early Hermès series, through to The Birth of Physics and later writings (...) on social and ethical themes, he keeps thermodynamical and informational – or ‘hard’ and ‘soft’ – understandings of entropy apart, while simultaneously exploring their relation. By focusing on the systematic significance of Serres’s ‘entropic difference’, this paper shows how it unfolds not necessarily as an ontological difference but as an operative function between the history and philosophy of science, epistemology, and a theory of negentropic (inter)subjectivity.

An explicit categorical equivalence is defined between a proper subvariety of the class of \-algebras, as defined by Di Nola and Dvurečenskij, to be called \-algebras, and the category of semi-low \-rings. This categorical representation is done using the prime spectrum of the \-algebras, through the equivalence between \-algebras and \-groups established by Mundici, from the perspective of the Dubuc–Poveda approach, that extends the construction defined by Chang on chains. As a particular case, semi-low \-rings associated to Boolean algebras are (...) characterized. (shrink)

Françoise Pasquier, qui vient de disparaître prématurément (Le Monde du 5 janvier 2001), était une figure marquante (bien que discrète) du mouvement féministe. Elle avait compris très vite qu’un mouvement politique qui ne peut pas faire connaître ses initiatives, ses analyses, ou son histoire, est condamné soit à la stérilité soit, à terme, à la disparition : elle engagea toute sa compétence, son talent, et une force de conviction peu commune dans la publication des textes issus du mouvement...

The World Unclaimed argues that Heidegger's critique of modern epistemology in Being and Time is seriously flawed.

There is a strong consensus among analytic philosophers that Husserl is an internalist and that his internalism must be understood in conjunction with his methodological solipsism. This paper focuses on Husserl's early work the, Logical Investigations , and explores whether such a reading is justified. It shows that Husserl is not a methodological solipsist: He neither believes that meaning can be reduced to the individual, nor does he assign an explanatory role for meaning to the subject. Explanatory priority is assigned (...) to objects which have an intrinsic property independently of any access or attitude we may have to them. Although not a methodological solipsist, there are nonetheless internalist elements to Husserl's thought: He believes that we can think of non-existent objects and his account of indexicals and demonstratives shows that there are two kinds of meaning: one is context independent and internally individuated, the other is partly determined by context and so externally individuated. The paper leaves it open whether this is sufficient to mark Husserl out as an internalist. However, even if he were considered as such, we can be sure of one thing, namely, that his internalism would not be a species of methodological solipsism. (shrink)

Un concepto que solía pertenecer al mundo de la informática (hacking) ahora se combina con las ciencias de la vida (bio). Sin gran dificultad, hemos empezado a ver la vida como un conjunto de datos, el ADN como un código, el cuerpo como una máquina y la mente como un software... todos susceptibles de ser leídos, manipulados y ahora incluso hackeados. ¿Pero manipulados por quiénes? Las comunidades de biohackers y DYIbio (do-it-yourself biology) quieren la biotecnología disponible para todos y la (...) información compartida abiertamente. En este trabajo, propongo una reflexión sobre qué está pasando y el posible por qué. En la primera parte, presento el biohacking como un fenómeno social, dando algunos ejemplos de biohackers y diferenciando tipos de biohackers. En la segunda parte, hago un acercamiento al Transhumanismo. La existencia de biohackers sólo es posible gracias a la creciente disponibilidad de información y biotecnología combinada con una cierta mentalidad. El principal objetivo es profundizar en la reflexión sobre la relación entre biohacking y Transhumanismo. Analizo el biohacking como una de las expresiones de este movimiento y uno de los fenómenos que contribuyen a él. Al final, ofrezco una reflexión sobre la cultura, deseos y miedos de nuestra sociedad, reconociendo también algunas de las preguntas que ellos provocan. (shrink)

When Husserl speaks of the so-called ‘transcendental reduction’ or ‘phenomenological epochē’ many believe that he is eschewing the question of truth or existence. Two reasons are given for this: First, Husserl explicitly states that when we perform the reduction, we should no longer naively ‘accept [the world] as it presents itself to me as factually existing’ (Id I §30, p. 53) and should suspend our judgement with regard to ‘the positing of its actual being’ (Id I §88, p. 182). Second, (...) Husserl seems to have no problem in referring to an ‘object’ of thought even when we refer to non-existent, hallucinatory or indeed impossible objects. This seems to suggest that he is not interested in the question whether or not there is a corresponding ‘ordinary’ object. The paper seeks to question this and will show that his inquiry never loses sight of the questions of truth and existence but rather brings them into the foreground. (shrink)

Corporate social responsibility has become a much-discussed subject in the business world. The Internet has become one of the main tools for CSR information disclosure, allowing companies to publicise more information less expensively and faster than ever before. As a result, corporations are increasingly concerned with communicating ethically and responsibly to the diversity of stakeholders through the web. This paper addresses the main question as whether CSR information disclosure on corporate websites is influenced by country of origin and/or industry sector. (...) Analysing the websites of 127 corporations from emerging countries, such as Brazil, Chile, China, India, Indonesia, Mexico, Thailand and South Africa, it becomes evident that both country of origin and industry sector have a significant influence over CSR information disclosure on the web . Based on the data studied, country of origin has a stronger influence over CSRIDOW than industry sector. (shrink)

En Giving Reasons: A Linguistic-pragmatic-approach to Argumentation Theory (Springer, 2011), propongo un nuevo modelo para la evaluación semántica y pragmática de la argumentación. Este modelo se basa en una caracterización de la argumentación como un acto de habla compuesto de segundo orden. Explico las ventajas de este modelo respecto de otras propuestas dentro de la Teoría de la Argumentación, tales como la Pragma-dialéctica, la Lógica Informal, la Nueva Retórica o el Enfoque Epistémico.

This paper takes Zahavi’s view to task that every conscious experience involves a “minimal sense of self.” Zahavi bases his claim on the observation that experience, even on the pre-reflective level, is not only about the object, but also has a distinctive qualitative aspect which is indicative of the fact that it is for me. It has the quality of what he calls “for-meness” or “mineness.” Against this I argue that there are not two phenomena but only one. On the (...) pre-reflective level, experience is transparent. Conscious experience may well be reflexive but this does not imply that I additionally have a sense of what it is like for me to have that experience. I do not just happen to disagree with Zahavi’s account of pre-reflective experience but, more importantly, I am concerned that he imposes it onto his interpretation of Edmund Husserl. Zahavi claims that when Husserl argues that consciousness is necessarily a form of self-consciousness, he must be committed to the view that we necessarily have a sense of ownership. However, Husserl only claims that I am self-conscious but not that I am a self that owns its consciousness. Zahavi thus misses the novelty of Husserl’s position, namely that I do not need to have a sense of abiding ownership, to have experience. (shrink)

This paper asks whether we should still be haunted by scepticism about other minds. It draws on the writings of Cavell and Husserl to show that there is some truth in the Cartesian premise that has given rise to scepticism about other minds, namely, that our self-awareness is of a fundamentally different type from our awareness of objects and other subjects. While this leads Cavell to argue that there is a truth to scepticism, it proves the opposite to Husserl, viz. (...) that other minds scepticism is necessarily non-sensical. The paper shows why Husserl's position is more convincing than Cavell's. 1. (shrink)

P F Strawson advocates a descriptive metaphysics. Contrary to Kant, he believes that metaphysics should be ‘content to describe the actual structure of thought about the world’, there is no need of postulating a world that lies beyond our grasp. We neither need to refute nor accept scepticism since we can ignore it with good reasons. Yet this paper argues that Strawson fails to provide us with good reasons. He fails to realise that one cannot do metaphysics by construing its (...) claims as being merely descriptive of a conceptual scheme we find ourselves to possess without even purporting to establish the legitimacy of that scheme. The paper shows that it is possible to overcome this impasse if we endorse Kant's transcendental idealist position. The significance of Kant' position is that it not only allows us to describe our conceptual scheme but moreover that it acknowledges that the world may be (radically) otherwise without however instantiating the truth of scepticism (Published Online October 13 2005) Footnotes1 I am grateful to Steven Kupfer for his helpful comments and should like to thank the Irish Research Council for the Humanities and Social Sciences for providing me with a year's fellowship which has made this study possible.
