This article provides an overview and analysis of recent work on the extended self, demonstrating that the boundaries of selves are fluid, shifting across biological, artifactual, and sociocultural structures. First, it distinguishes the notions of minimal self, person, and narrative self. Second, it surveys how philosophers, psychologists, and cognitive scientists argue that embodiment, cognition, emotion, consciousness, and moral character traits can be extended and what that implies for the boundaries of selves. It also reviews and responds to various criticisms and (...) counterarguments against the extended self. The main focus is on the link between the extended mind and extended self, which has received the most attention in recent literature. But accounts of the extended self developed independently of the extended mind are also briefly discussed. This article ends by drawing out some of the conceptual, methodological, and normative implications of the extended self and suggesting some directions for future research. (shrink)

The period from 1900 to 1935 was particularly fruitful and important for the development of logic and logical metatheory. This survey is organized along eight "itineraries" concentrating on historically and conceptually linked strands in this development. Itinerary I deals with the evolution of conceptions of axiomatics. Itinerary II centers on the logical work of Bertrand Russell. Itinerary III presents the development of set theory from Zermelo onward. Itinerary IV discusses the contributions of the algebra of logic tradition, in particular, Löwenheim (...) and Skolem. Itinerary V surveys the work in logic connected to the Hilbert school, and itinerary V deals specifically with consistency proofs and metamathematics, including the incompleteness theorems. Itinerary VII traces the development of intuitionistic and many-valued logics. Itinerary VIII surveys the development of semantical notions from the early work on axiomatics up to Tarski's work on truth. (shrink)

According to the PubMed resource from the U.S. National Library of Medicine, over 750,000 scientific articles have been published in the ~5000 biomedical journals worldwide in the year 2007 alone. The vast majority of these publications include results from hypothesis-driven experimentation in overlapping biomedical research domains. Unfortunately, the sheer volume of information being generated by the biomedical research enterprise has made it virtually impossible for investigators to stay aware of the latest findings in their domain of interest, let alone to (...) be able to assimilate and mine data from related investigations for purposes of meta-analysis. While computers have the potential for assisting investigators in the extraction, management and analysis of these data, information contained in the traditional journal publication is still largely unstructured, free-text descriptions of study design, experimental application and results interpretation, making it difficult for computers to gain access to the content of what is being conveyed without significant manual intervention. In order to circumvent these roadblocks and make the most of the output from the biomedical research enterprise, a variety of related standards in knowledge representation are being developed, proposed and adopted in the biomedical community. In this chapter, we will explore the current status of efforts to develop minimum information standards for the representation of a biomedical experiment, ontologies composed of shared vocabularies assembled into subsumption hierarchical structures, and extensible relational data models that link the information components together in a machine-readable and human-useable framework for data mining purposes.

In his Moderate Realism and Its Logic (Yale, 1996), Donald Mertz argues that the traditional ontology of nonpredicable substances and predicable universals is beset by “intractable problems,” “harbors an insidious error,” and constitutes a “stumbling block” for the ontologist. By contrast, a onecategory ontology consisting of relation instances (and combinations thereof) is sustainable, and indeed the only way of avoiding commitment to bare particulars. The success of the project turns on Mertz’s claim that every relation instance has a linking aspect, (...) so that (in a sense) even Socrates is a predicate. I argue that, ironically, it is this very feature of a relation instance that undermines Mertz’s entire theory of predication, effectively preventing any connections from being formed between the instances that allegedly compose an ordinary individual such as Socrates.

Space-time intervals are the fundamental components of conscious experience, gravity, and a Theory of Everything. Space-time intervals are relationships that arise naturally between events. They have a general covariance (independence of coordinate systems, scale invariance), a physical constancy, that encompasses all frames of reference. There are three basic types of space-time intervals (light-like, time-like, space-like) which interact to create space-time and its properties. Human conscious experience is a four-dimensional space-time continuum created through the processing of space-time intervals by the brain; (...) space-time intervals are the source of conscious experience (observed physical reality). Human conscious experience is modeled by Einstein’s special theory of relativity, a theory designed specifically from the general covariance of space-time intervals (for inertial frames of reference). General relativity is our most accurate description of gravity. In general relativity, the general covariance of space-time intervals is extended to all frames of reference (inertial and non-inertial), including gravitational reference frames; space-time intervals are the source of gravity in general relativity. The general covariance of space-time intervals is further extended to quantum mechanics; space-time intervals are the source of quantum gravity. The general covariance of space-time intervals seamlessly merges general relativity with quantum field theory (the two grand theories of the universe). Space-time intervals consequently are the basis of a Theory of Everything (a single all-encompassing coherent theoretical framework of physics that fully explains and links together all physical aspects of the universe). This theoretical framework encompasses our observed physical reality (conscious experience) as well; space-time intervals link observed physical reality to actual physical reality. This provides an accurate and reliable match between observed physical reality and the physical universe by which we can carry on our activity. The Minkowski metric, which defines generally covariant space-time intervals, may be considered an axiom (premise, postulate) for the Theory of Everything. (shrink)

Conscious experience is the direct observation of conscious events. Human conscious experience is four-dimensional. Conscious events are linked (associated) by spacetime intervals to produce a coherent conscious experience. This explains why conscious experience appears to us the way it does. Conscious experience is an orientation in space and time, an understanding of the position of the observer in space and time. Causality, past-future relations, learning, memory, cognitive processing, and goal-directed actions all evolve from four-dimensional conscious experience. A neural correlate for (...) four-dimensional conscious experience can be found in the human brain and is modelled by Einstein's special theory of relativity. The relativistic concept of spacetime interval is central for understanding conscious experience and cognition. (shrink)

In Newton’s correspondence with Richard Bentley, Newton rejected the possibility of remote action, even though he accepted it in the Principia. Practically, Newton’s natural philosophy is indissolubly linked to his conception of God. The knowledge of God seems to be essentially immutable, unlike the laws of nature that can be subjected to refining, revision and rejection procedures. As Newton later states in Opticks, the cause of gravity is an active principle in matter, but this active principle is not an (...) essential aspect of matter, but something that must have been added to matter by God, arguing in the same Query of Opticks even the need for divine intervention.

A synthetic glance about the basic outlines of Hare's Meta-ethics is offered in this paper to support the idea that Hume's law is still a productive resource for ethical studies. Hare accepted the emotivist premise that moral judgments do not, in the same way as ordinary statements do, state matters of fact that are either true or false, but denied that therefore they must be forms of exclamation. The essential character of moral discourse consisted, not, as the emotivists had held, (...) in its links with subjective attitudes, but with action; moral judgments were prescriptive, in that they expressed commitments to action on the part of the person uttering them, and at the same time their rationality was assured by their universalisability, i.e. their property of applying not merely to the person uttering them, but to all similar persons in similar circumstances.

This essay considers Richard Calder’s Dead trilogy as an important contribution to the argument concerning how pornography’s pernicious effects might be mitigated or disrupted. Paying close attention to the way that Calder uses the rhetoric of fiction to challenge pornographic stereotypes that have achieved hegemonic status, the essay argues that Calder’s trilogy provides an important link between debates about pornography and contemporary philosophical discussions of alterity and community. Finally, it argues that, for Calder, sexuality is implicitly predicated on (...) a reconceptualization of social relations in general – a reconceptualization achieved through the exhaustion of that decadent shadow of the Enlightenment, pornography.

B a c k g r o u n d . The article is devoted to the Minnemystik of Hadewijch of Brabant in the XIII century. It deals with the genesis of Hadewijch's concept of Minne in its relation to the monastic Cistercian mysticism of Bernard of Clairvaux, William of Saint-Thierry in the XII century and Beatrice of Nazareth in the XIII century. It also considers the conception of theologist and philosopher Richard of Saint-Victor in the XII century. Considering (...) the existing advances of researchers on Hadewijch's Minnemystik, since the XX century, this investigation especially focuses on the primary role of the secular tradition of minnesingers and trobairitz of the mid-XIII century in her texts. M e t h o d s . The main method of the article is a comparative analysis. It is used to find the common meaning of Minne in two traditions: secular and religious minnesingers. The historical-philosophical approach allows us to demonstrate the conceptual link between monastic theology in the XII–XIII centuries and Hadewijch's beguinal Minnemystik. R e s u l t s . The article sheds light on Hadewijch's concept of the Minne and stresses the primary role of the secular and religious conceptions of predecessors and contemporaries in Hadewijch's Minnemystik. C o n c l u s i o n . The author underlines that Hadewijch's concept of Minne comes from the secular tradition of minnesingers and, especially, trobairitz. It also derives from the XII-century male and female mystic theology, which follows Augustine. Thus, the concept of the Minne is deeply connected with the notion of Amor and the tradition of "courtly love", and with Caritas and the tradition of "pure love". K e y w o r d s : Hadewijch's concept of the Minne, Caritas, trobairitz, minnesingers, troubadours, Minnemystik, Unio Mystica, William of Saint-Thierry, Beatrice of Nazareth, Richard of Saint-Victor, Bernard of Clairvaux.

Thirty years ago Richard Rorty detected the similarities between Wittgenstein's Philosophical Investigations (1953) and the philosophical framework of Charles S. Peirce (1839-1914), the founder of pragmatism. Rorty tried to show that Peirce envisaged and repudiated in advance logical positivism and developed insights and a philosophical mood very close to the analytical philosophers influenced by the later Wittgenstein (Rorty 1961). In spite of that, the majority of scholars have considered both thinkers as totally alien. Some scholars have attributed the pragmatist (...) flavor of the Philosophical Investigations to the influence of Frank P. Ramsey, who awoke Wittgenstein from the dogmatic slumber of the Tractatus. Nevertheless, the real scope of the influence of American pragmatist philosophy in Wittgenstein's later thought is not clearly known. The purpose of my paper is not to describe the common themes between Wittgenstein and Peirce, but the way in which recent scholarship has established some links between both philosophers. -/- .

The cover illustration for Richard Joyce’s elegant and powerful recent work, The Evolution of Morality, is a reproduction of an oddly fascinating and disturbing sixteenth-century engraving, the Anatomia del corpo humano. One has to examine the image for a minute to realize that the standing human figure, stripped of skin, and with muscles, tendons and joints revealed, holds the anatomist’s knife in his left hand and that, with his right, he holds up the single piece of skin, from bearded (...) face to dangling extremities, that had once covered his body. This is the anatomist self-flayed, revealed to inspection by his own knife. A double worry is suggested: the body without the skin may have surprising, or disquieting, features. There is no assurance that what is revealed will accord with our preconceptions. Additionally, there is the thought that only the artist’s magic, freezing a moment in time, permits the body to maintain its integrity. In reality, the body of the self-flayer would collapse and die in short order. -/- Richard Joyce similarly undertakes to wield the analytic knife of science and philosophy to cut away the surface appearance of the moral sense and see what lies beneath. Again, what we find may be surprising or disquieting. Beneath the surface, we find the once-hidden articulation of the moral sensibility. We see its parts, how they are connected, how one links to another. And we may also suspect or fear that what remains cannot long stand inspection in such a state. It may be, indeed, that “we murder to dissect.” And if so, then like the self-flayer, we are ourselves the victims. (shrink)

An influential tradition holds that thoughts are public: different thinkers share many of their thoughts, and the same applies to a single subject at different times. This ‘publicity principle’ has recently come under attack. Arguments by Mark Crimmins, Richard Heck and Brian Loar seem to show that publicity is inconsistent with the widely accepted principle that someone who is ignorant or mistaken about certain identity facts will have distinct thoughts about the relevant object—for instance, the astronomer who does not (...) know that Hesperus is Phosphorus will have two distinct thoughts Hesperus is bright and Phosphorus is bright. In this paper, I argue that publicity can be defended if we adopt a relational account on which thoughts are individuated by their mutual relations. I then go on to develop a specific relational theory—the ‘linking account’—and contrast it with other relational views. (shrink)

I begin by distinguishing four different versions of the argument from evil that start from four different moral premises that in various ways link the existence of God to the absence of suffering. The version of the argument from evil that I defend starts from the premise that if God exists, he would not allow excessive, unnecessary suffering. The argument continues by denying the consequent of this conditional to conclude that God does not exist. I defend the argument against (...) Skeptical Theists who say we are in no position to judge that there is excessive, unnecessary suffering by arguing that this defense has absurd consequences. It allows Young Earthers to construct a parallel argument that concludes that we are in no position to judge that God did not create the earth recently. In the last section I consider whether theists can turn the argument from evil on its head by arguing that God exists. I first criticize Alvin Plantinga’s theory of warrant that one might try to use to argue for God’s existence. I then criticize Richard Swinburne’s Bayesian argument to the same conclusion. I conclude that my version of the argument from evil is a strong argument against the existence of God and that several important responses to it do not defeat it. (shrink)

"Subjectivisation of Sense Perception and Two Models of Early Modern Idealism" The distinction between primary and secondary qualities, most famously outlined by Galileo, and subsequently supported, inter alia, by Descartes and by Locke has widely been considered one of the crucial factors in the development of modern idealism. In its contemporary form, the distinction identifies some of the perceived properties as mental phenomena due to their content and structural dependence on the mind. However, this account of the primary/secondary distinction is (...) largely different from its original version developed by the above-mentioned philosophers, within whose work the mental being of the perceived qualities was demonstrated objectively, from the conceptually-derived nature of matter, and not subjectively, by referring to the mind’s participation in the cognitive process. It was only at the next stage of the early modern subjectivisation of sense perception, best exemplified by such philosophers as Arnold Geulincx and Richard Burthogge, that the creative role played by the mind in sensation and, consequently, the mind-dependency of the sensible qualities was recognised – a turn influenced by the reinterpretation of Aristotelian philosophy offered by Jacopo Zabarella and Paduan school as well as by Anti-Aristotelianism of the kind developed in Netherlands. Furthermore, the two different approaches to the primary/secondary distinction can be linked with two main types of post-Cartesian idealism, i.e. Berkeleian and Kantian – a claim for which illustrative evidence from British philosophy, namely from Berkeley’s and Burthogge’s respective theories, can be drawn.

“There’s Plenty of Room at the Bottom”, said the title of Richard Feynman’s 1959 seminal conference at the California Institute of Technology. Fifty years on, nanotechnologies have led computer scientists to pay close attention to the links between physical reality and information processing. Not all the physical requirements of optimal computation are captured by traditional models—one still largely missing is reversibility. The dynamic laws of physics are reversible at microphysical level, distinct initial states of a system leading to distinct (...) final states. On the other hand, as von Neumann already conjectured, irreversible information processing is expensive: to erase a single bit of information costs ~3 × 10−21 joules at room temperature. Information entropy is a thermodynamic cost, to be paid in non-computational energy dissipation. This paper addresses the problem drawing on Edward Fredkin’s Finite Nature hypothesis: the ultimate nature of the universe is discrete and finite, satisfying the axioms of classical, atomistic mereology. The chosen model is a cellular automaton with reversible dynamics, capable of retaining memory of the information present at the beginning of the universe. Such a CA can implement the Boolean logical operations and the other building bricks of computation: it can develop and host all-purpose computers. The model is a candidate for the realization of computational systems, capable of exploiting the resources of the physical world in an efficient way, for they can host logical circuits with negligible internal energy dissipation.

This paper investigates a famous argument, first introduced by Richard Taylor, that attempts to establish a radical similarity in the concepts of space and time. The argument contends that the spatial and temporal aspects of material bodies are much more alike, or analogous, than has been hitherto acknowledged. As will be demonstrated, most of the previous investigations of Taylor and company have failed to pinpoint the weakest link in their complex of analogies. By concentrating on their most fundamental (...) cases, however, a substantial difference, or disanalogy, can be brought to light that undermines this purported equivalence of space and time.

In this fine book, David Owens presents a new theory of causation based on the idea that the notions of cause and coincidence are intimately related. That there is a link between the concept of cause and the concept of coincidence is not news. As Richard Sorabji has argued, Aristotle thought that coincidences cannot be explained. What is new in Owens's book is the claim that this apparent truism can form the basis of a full-scale analysis of causation.

A uniform construction for sequent calculi for finite-valued first-order logics with distribution quantifiers is exhibited. Completeness, cut-elimination and midsequent theorems are established. As an application, an analog of Herbrand’s theorem for the four-valued knowledge-representation logic of Belnap and Ginsberg is presented. It is indicated how this theorem can be used for reasoning about knowledge bases with incomplete and inconsistent information.

Alongside existing research into the social, political and economic impacts of the Web, there is a need to study the Web from a cognitive and epistemic perspective. This is particularly so as new and emerging technologies alter the nature of our interactive engagements with the Web, transforming the extent to which our thoughts and actions are shaped by the online environment. Situated and ecological approaches to cognition are relevant to understanding the cognitive significance of the Web because of the emphasis (...) they place on forces and factors that reside at the level of agent–world interactions. In particular, by adopting a situated or ecological approach to cognition, we are able to assess the significance of the Web from the perspective of research into embodied, extended, embedded, social and collective cognition. The results of this analysis help to reshape the interdisciplinary configuration of Web Science, expanding its theoretical and empirical remit to include the disciplines of both cognitive science and the philosophy of mind.

It is shown that Gqp↑, the quantified propositional Gödel logic based on the truth-value set V↑ = {1 - 1/n : n≥1}∪{1}, is decidable. This result is obtained by reduction to Büchi's theory S1S. An alternative proof based on elimination of quantifiers is also given, which yields both an axiomatization and a characterization of Gqp↑ as the intersection of all finite-valued quantified propositional Gödel logics.

The Ontology for Biomedical Investigations (OBI) is an ontology that provides terms with precisely defined meanings to describe all aspects of how investigations in the biological and medical domains are conducted. OBI re-uses ontologies that provide a representation of biomedical knowledge from the Open Biological and Biomedical Ontologies (OBO) project and adds the ability to describe how this knowledge was derived. We here describe the state of OBI and several applications that are using it, such as adding semantic expressivity to (...) existing databases, building data entry forms, and enabling interoperability between knowledge resources. OBI covers all phases of the investigation process, such as planning, execution and reporting. It represents information and material entities that participate in these processes, as well as roles and functions. Prior to OBI, it was not possible to use a single internally consistent resource that could be applied to multiple types of experiments for these applications. OBI has made this possible by creating terms for entities involved in biological and medical investigations and by importing parts of other biomedical ontologies such as GO, Chemical Entities of Biological Interest (ChEBI) and Phenotype Attribute and Trait Ontology (PATO) without altering their meaning. OBI is being used in a wide range of projects covering genomics, multi-omics, immunology, and catalogs of services. OBI has also spawned other ontologies (Information Artifact Ontology) and methods for importing parts of ontologies (Minimum information to reference an external ontology term (MIREOT)). The OBI project is an open cross-disciplinary collaborative effort, encompassing multiple research communities from around the globe. To date, OBI has created 2366 classes and 40 relations along with textual and formal definitions. The OBI Consortium maintains a web resource providing details on the people, policies, and issues being addressed in association with OBI. (shrink)

Autonomy has been central to moral and political philosophy for millenia, and has been positioned as a critical aspect of both justice and wellbeing. Research in psychology supports this position, providing empirical evidence that autonomy is critical to motivation, personal growth and psychological wellness. Responsible AI will require an understanding of, and ability to effectively design for, human autonomy (rather than just machine autonomy) if it is to genuinely benefit humanity. Yet the effects on human autonomy of digital experiences are (...) neither straightforward nor consistent, and are complicated by commercial interests and tensions around compulsive overuse. This multi-layered reality requires an analysis that is itself multidimensional and that takes into account human experience at various levels of resolution. We borrow from HCI and psychological research to apply a model (“METUX”) that identifies six distinct spheres of technology experience. We demonstrate the value of the model for understanding human autonomy in a technology ethics context at multiple levels by applying it to the real-world case study of an AI-enhanced video recommender system. In the process we argue for the following three claims: 1) There are autonomy-related consequences to algorithms representing the interests of third parties, and they are not impartial and rational extensions of the self, as is often perceived; 2) Designing for autonomy is an ethical imperative critical to the future design of responsible AI; and 3) Autonomy-support must be analysed from at least six spheres of experience in order to approriately capture contradictory and downstream effects.

Bayesian models of legal arguments generally aim to produce a single integrated model, combining each of the legal arguments under consideration. This combined approach implicitly assumes that variables and their relationships can be represented without any contradiction or misalignment, and in a way that makes sense with respect to the competing argument narratives. This paper describes a novel approach to compare and ‘average’ Bayesian models of legal arguments that have been built independently and with no attempt to make them consistent (...) in terms of variables, causal assumptions or parameterization. The approach involves assessing whether competing models of legal arguments are explained or predict facts uncovered before or during the trial process. Those models that are more heavily disconfirmed by the facts are given lower weight, as model plausibility measures, in the Bayesian model comparison and averaging framework adopted. In this way a plurality of arguments is allowed yet a single judgement based on all arguments is possible and rational. (shrink)

All first-order Gödel logics G_V with globalization operator based on truth value sets V C [0,1] where 0 and 1 lie in the perfect kernel of V are axiomatized by Ciabattoni’s hypersequent calculus HGIF.

It is shown that the infinite-valued first-order Gödel logic G° based on the set of truth values {1/k: k ε w {0}} U {0} is not r.e. The logic G° is the same as that obtained from the Kripke semantics for first-order intuitionistic logic with constant domains and where the order structure of the model is linear. From this, the unaxiomatizability of Kröger's temporal logic of programs (even of the fragment without the nexttime operator O) and of the authors' temporal (...) logic of linear discrete time with gaps follows.

We present a general framework for representing belief-revision rules and use it to characterize Bayes's rule as a classical example and Jeffrey's rule as a non-classical one. In Jeffrey's rule, the input to a belief revision is not simply the information that some event has occurred, as in Bayes's rule, but a new assignment of probabilities to some events. Despite their differences, Bayes's and Jeffrey's rules can be characterized in terms of the same axioms: "responsiveness", which requires that revised beliefs (...) incorporate what has been learnt, and "conservativeness", which requires that beliefs on which the learnt input is "silent" do not change. To illustrate the use of non-Bayesian belief revision in economic theory, we sketch a simple decision-theoretic application. (shrink)

A construction principle for natural deduction systems for arbitrary, finitely-many-valued first order logics is exhibited. These systems are systematically obtained from sequent calculi, which in turn can be automatically extracted from the truth tables of the logics under consideration. Soundness and cut-free completeness of these sequent calculi translate into soundness, completeness, and normal-form theorems for natural deduction systems.

All disciplines must define their basic units and core processes. In evolutionary biology, the core process is natural selection and the basic unit of selection and adaptation is the individual. To operationalize the theory of natural selection we must count individuals, as they are the bearers of fitness. While canonical individuals have often been taken to be multicellular organisms, the hierarchy of life shows that new kinds of individuals have evolved. A variety of criteria have been used to define biological (...) individuality. Some criteria rely on the presence/absence of a particular property while others advocate an approach that reflects the process of natural selection. The plethora of approaches to classifying individuality has resulted in confusion regarding how to study individuality in a given taxon. (shrink)

In Mind and World, John McDowell argues against the view that perceptual representation is non-conceptual. The central worry is that this view cannot offer any reasonable account of how perception bears rationally upon belief. I argue that this worry, though sensible, can be met, if we are clear that perceptual representation is, though non-conceptual, still in some sense 'assertoric': Perception, like belief, represents things as being thus and so.

The aim of this paper is to emphasize the fact that for all finitely-many-valued logics there is a completely systematic relation between sequent calculi and tableau systems. More importantly, we show that for both of these systems there are al- ways two dual proof sytems (not just only two ways to interpret the calculi). This phenomenon may easily escape one’s attention since in the classical (two-valued) case the two systems coincide. (In two-valued logic the assignment of a truth value and (...) the exclusion of the opposite truth value describe the same situation.). (shrink)

The literature on the history of electricity production have studied the evolution of electricity in both developed and developing countries and its impact on their economies. Some have laid foundations upon which other works are carried out. A close examination of historiography and multidisciplinary research on electricity production in Ghana shows that more efforts are required to improve the electric power landscape in Ghana. From the colonial era, the increasing demand for electricity has been the biggest challenge plaguing the energy (...) sector. Respective governments have made significant strides in ensuring reliable and universal access to electricity throughout Ghana, yet such efforts have been accompanied by different levels of challenges. The study uses a qualitative and exploratory research approach to trace the activities that helped, in many other ways to the creation of a sustainable electric power provision to household and industry in Ghana, particularly in two of Ghana’s cities; Accra and Kumasi, within the period 1900 to the1960s. The work focused mainly on archival sources in its quest to arrive at how indigenous Ghanaians provided power for industrial activities and for household purposes. Results from the study show that local and cottage industries relied predominantly on wood, fuel, and biomass for their operations even before the introduction of the more sophisticated means of power generation. Also, the study revealed that in finding solutions to the challenges of electricity production, policymakers have focused more on current issues with little or no effort to trace the historical foundation of electricity production. This notwithstanding, the little efforts that have been made examined the history of energy production, with a limited focus on the immediate post-independence era. (shrink)

Women have always been central concerning the provision of healthcare. The transitions into the modern world have been very slow for women because of how societies classify women. Starting from lay care, women provided healthcare for their family and sometimes to the members of the community in which they lived. With no formal education, women served as midwives and served in other specialised fields in medicine. They usually treated their fellow women because they saw ‘women’s medicine’ as women’s business. They (...) were discriminated against by the opposite sex and by the church, which regarded it as a taboo to allow women to practice medicine. This study points to a Ghanaian context on how the charismas of women have made them excel in their efforts to provide healthcare for their people. The study also focused on the role of indigenous practitioners who are mostly found in the rural areas and modern practitioners who are mostly found in the peri-urban, urban areas and larger cities in Ghana.

The proof theory of many-valued systems has not been investigated to an extent comparable to the work done on axiomatizatbility of many-valued logics. Proof theory requires appropriate formalisms, such as sequent calculus, natural deduction, and tableaux for classical (and intuitionistic) logic. One particular method for systematically obtaining calculi for all finite-valued logics was invented independently by several researchers, with slight variations in design and presentation. The main aim of this report is to develop the proof theory of finite-valued first order (...) logics in a general way, and to present some of the more important results in this area. In Systems covered are the resolution calculus, sequent calculus, tableaux, and natural deduction. This report is actually a template, from which all results can be specialized to particular logics.

In an earlier paper, "Non-conceptual Content and the 'Space of Reasons'", I distinguished two forms of the view that perceptual content is non-conceptual, which I called the 'state view' and the 'content view'. On the latter, but not the former, perceptual states have a different kind of content than do cognitive states. Many have found it puzzling why anyone would want to make this claim and, indeed, what it might mean. This paper attempts to address these questions.

Frege held that referring expressions in general, and demonstratives and indexicals in particular, contribute more than just their reference to what is expressed by utterances of sentences containing them. Heck first attempts to get clear about what the essence of the Fregean view is, arguing that it rests upon a certain conception of linguistic communication that is ultimately indefensible. On the other hand, however, he argues that understanding a demonstrative (or indexical) utterance requires one to think of the object denoted (...) in an appropriate way. This fact makes it difficult to reconcile the view that referring expressions are "directly referential" with any view that seeks (as Grice's does) to ground meaning in facts about communication.

Vaccine research, as well as the development, testing, clinical trials, and commercial uses of vaccines involve complex processes with various biological data that include gene and protein expression, analysis of molecular and cellular interactions, study of tissue and whole body responses, and extensive epidemiological modeling. Although many data resources are available to meet different aspects of vaccine needs, it remains a challenge how we are to standardize vaccine annotation, integrate data about varied vaccine types and resources, and support advanced vaccine (...) data analysis and inference. To address these problems, the community-based Vaccine Ontology (VO) has been developed through collaboration with vaccine researchers and many national and international centers and programs, including the National Center for Biomedical Ontology (NCBO), the Infectious Disease Ontology (IDO) Initiative, and the Ontology for Biomedical Investigations (OBI). VO utilizes the Basic Formal Ontology (BFO) as the top ontology and the Relation Ontology (RO) for definition of term relationships. VO is represented in the Web Ontology Language (OWL) and edited using the Protégé-OWL. Currently VO contains more than 2000 terms and relationships. VO emphasizes on classification of vaccines and vaccine components, vaccine quality and phenotypes, and host immune response to vaccines. These reflect different aspects of vaccine composition and biology and can thus be used to model individual vaccines. More than 200 licensed vaccines and many vaccine candidates in research or clinical trials have been modeled in VO. VO is being used for vaccine literature mining through collaboration with the National Center for Integrative Biomedical Informatics (NCIBI). Multiple VO applications will be presented. (shrink)

Angell's logic of analytic containment AC has been shown to be characterized by a 9-valued matrix NC by Ferguson, and by a 16-valued matrix by Fine. We show that the former is the image of a surjective homomorphism from the latter, i.e., an epimorphic image. The epimorphism was found with the help of MUltlog, which also provides a tableau calculus for NC extended by quantifiers that generalize conjunction and disjunction.

First, based on their functional properties, I identify four categories of artifacts co-opted by the embodied mind, namely (1) embodied artifacts, (2) perceptual artifacts, (3) cognitive artifacts, and (4) affective artifacts. These categories can overlap and (...) so some artifacts are members of more than one category. I also identify some of the techniques (or skills) we use when interacting with artifacts. Identifying these categories of artifacts and techniques allows us to map the landscape of relations between embodied minds and the artifactual world. Second, having identified categories of artifacts and techniques, this essay then outlines some of the trends in the design and use of artifacts, focussing on neuroprosthetics, brain-computer interfaces, and personalisation algorithms nudging their users towards particular epistemic paths of information consumption.

This report from the WHO Consultative Group on Equity and Universal Health Coverage offers advice on how to make progress fairly towards universal health coverage.

In The Boundary Stones of Thought, Rumfitt defends classical logic against challenges from intuitionistic mathematics and vagueness, using a semantics of pre-topologies on possibilities, and a topological semantics on predicates, respectively. These semantics are suggestive but the characterizations of negation face difficulties that may undermine their usefulness in Rumfitt’s project.

Whilst media and political rhetoric in Britain is sceptical and often outright damning of the (presumed) morals and behaviours of the White marginalized poor, our aim is to explore the conditions under which successful communities are nevertheless built. Specifically, we examine the features of community and stress its importance both for belonging and bonding around shared norms and practices and for fostering the necessary bridging essential for interacting and cooperating with others. In considering what it means to foster a community (...) that acts as a breakwater against the tides of stigma or disadvantage, we pay special attention to what we will call enabling conditions – essential features that communities either can or should be able to provide or that exist independent of communities and are indispensable for accessing opportunities in the wider society. We detail the dynamics of White poverty and exclusion before turning our attention to possible responses to these challenges. In searching for viable responses to stigma and disadvantage, we compare some different typologies of community presently available to the White poor in Britain and examine whether these are sufficient to satisfy the enabling conditions associated with more robust forms of group membership.

Epistemologists who study credences have a well-developed account of how you should change them when you learn new evidence; that is, when your body of evidence grows. What's more, they boast a diverse range of epistemic and pragmatic arguments that support that account. But they do not have a satisfactory account of when and how you should change your credences when you become aware of possibilities and propositions you have not entertained before; that is, when your awareness grows. In this (...) paper, I consider the arguments for the credal epistemologist's account of how to respond to evidence, and I ask whether they can help us generate an account of how to respond to awareness growth. The results are surprising: the arguments that all support the same norms for responding to evidence growth support a number of different norms when they are applied to awareness growth. Some of these norms seem too weak, others too strong. I ask what we should conclude from this, and argue that our credal response to awareness growth is considerably less rigorously constrained than our credal response to new evidence. (shrink)

Effective altruism sounds so innocuous—who could possibly be opposed to doing good more effectively? Yet it has inspired significant backlash in recent years. This paper addresses some common misconceptions and argues that the core “beneficentric” ideas of effective altruism are both excellent and widely neglected. Reasonable people may disagree on details of implementation, but all should share the basic goals or values underlying effective altruism.

The desirability of what actually occurs is often influenced by what could have been. Preferences based on such value dependencies between actual and counterfactual outcomes generate a class of problems for orthodox decision theory, the best-known perhaps being the so-called Allais Paradox. In this paper we solve these problems by extending Richard Jeffrey's decision theory to counterfactual prospects, using a multidimensional possible-world semantics for conditionals, and showing that preferences that are sensitive to counterfactual considerations can still be desirability maximising. (...) We end the paper by investigating the conditions necessary and sufficient for a desirability function to be an expected utility. It turns out that the additional conditions imply highly implausible epistemic principles. (shrink)

Methods available for the axiomatization of arbitrary finite-valued logics can be applied to obtain sound and complete intelim rules for all truth-functional connectives of classical logic including the Sheffer stroke and Peirce’s arrow. The restriction to a single conclusion in standard systems of natural deduction requires the introduction of additional rules to make the resulting systems complete; these rules are nevertheless still simple and correspond straightforwardly to the classical absurdity rule. Omitting these rules results in systems for intuitionistic versions of (...) the connectives in question. (shrink)
