We consider a 2-valued non-deterministic connective \({\wedge \!\!\!\!\!\vee }\) defined by the table resulting from the entry-wise union of the tables of conjunction and disjunction. Being half conjunction and half disjunction we named it _platypus_. The value of \({\wedge \!\!\!\!\!\vee }\) is not completely determined by the input, contrasting with usual notion of Boolean connective. We call non-deterministic Boolean connective any connective based on multi-functions over the Boolean set. In this way, non-determinism allows for an extended (...) notion of truth-functional connective. Unexpectedly, this very simple connective and the logic it defines, illustrate various key advantages in working with generalized notions of semantics (by incorporating non-determinism), calculi (by allowing multiple-conclusion rules) and even of logic (moving from Tarskian to Scottian consequence relations). We show that the associated logic cannot be characterized by any finite set of finite matrices, whereas with non-determinism two values suffice. Furthermore, this logic is not finitely axiomatizable using single-conclusion rules, however we provide a very simple analytic multiple-conclusion axiomatization using only two rules. Finally, deciding the associated multiple-conclusion logic is \(\mathbf {coNP}\) -complete, but deciding its single-conclusion fragment is in \({\mathbf {P}}\). (shrink)

This paper provides an overview of connective knowledge. It is intended to be an introduction, expressed as non-technically as possible.

Social media offers a platform for diffused stakeholders to interact with firms—alternatively praising, questioning, and chastising businesses for their CSR performance and seeking to engage in two-way dialogue. In 2014, 163,402 public messages were sent to Fortune 200 firms’ CSR-focused Twitter accounts, each of which was either shared, replied to, “liked,” or ignored by the targeted firm. This paper examines firm reactions to these messages, building a model of firm response to stakeholders that combines the notions of CSR communication and (...) stakeholder salience. Our findings show that firm response to a stakeholder on social media is positively and most significantly associated with what we refer to as the stakeholder’s connective power but negatively associated with the firm’s own connective power. To a lesser extent, firm response is positively associated with the stakeholder’s normative power but negatively associated with the firm’s own normative power. Firm response is also shown to be positively associated with stakeholder urgency in terms of both the originality of a stakeholder message and the expression of positive sentiment. (shrink)

The Japanese connective de has been found to be the most frequently occurring connective in spontaneous conversation. Yet, studies on de have been rather scarce compared to other connectives such as demo ‘but’ and dakara ‘so; therefore’. The current study examines the occurrence of this highly frequent connective and demonstrates its very distinctive characteristics in on-line interaction. The results reveal a unique and ambiguous status of de, which behaves like an independent word at times but also shows (...) prefix-like usage at other times. That is, de seems to have some properties that clitics have, in that it is not like a typical independent word, and is not like a typical bound morpheme, either. An examination of de in naturally occurring conversation supports and calls into question the notion of ‘categorization’. (shrink)

The purpose of this chapter is to outline some of the thinking behind new e-learning technology, including e-portfolios and personal learning environments. Part of this thinking is centered around the theory of connectivism, which asserts that knowledge - and therefore the learning of knowledge - is distributive, that is, not located in any given place (and therefore not 'transferred' or 'transacted' per se) but rather consists of the network of connections formed from experience and interactions with a knowing community. And (...) another part of this thinking is centered around the new, and the newly empowered, learner, the member of the net generation, who is thinking and interacting in new ways. These trends combine to form what is sometimes called 'e-learning 2.0' - an approach to learning that is based on conversation and interaction, on sharing, creation and participation, on learning not as a separate activity, but rather, as embedded in meaningful activities such as games or workflows.

Accounts based on the pragmatic maxim of quantity make different predictions about the computation of scalar versus ignorance inferences. These different predictions are evaluated in two eye-tracking experiments using a visual world paradigm to assess the on-line computation of inferences. The test sentences contained disjunction phrases, which engender both kinds of inferences. The first experiment documented that both inferences are computed immediately upon encountering the disjunctive connective, at nearly identical temporal locations. The second experiment was designed to determine whether (...) or not there exists an intermediate stage at which the truth of the corresponding conjunction phrase is ignored. No such stage was found.

In the article the basic procedures for finding of connective elements and resolving conflicts of references is analyzed. On the basis of this, a generalized algorithm is proposed that combines advantages of existing procedures for search for connective elements between phrases. The advantages of the selected procedures and their sequence are described, the formal description of input data and the results of the algorithm are presented. To optimize the procedure for scanning the text, the algorithm is performed as (...) an iterative reduction of the candidates for communication elements. This is achieved through the confirmation of non-conflict links and the gradual resolution of conflicts. (shrink)

A profusion of jobs has arisen in contemporary capitalism involving ‘connective labor’, or the work of emotional recognition. Yet the expansion of this interpersonal work occurs at the same time as its systematization, as pressures of efficiency, measurement and automation reshape the work, generating a ‘colliding intensification’. Existing scholarship offers three different ways of understanding the role of emotions in connective labor – as tool, commodity or vulnerability – depending on their view of systematization as useful, inseparable or (...) dehumanizing. Based on 106 in-depth interviews and 300+ hours of observations, I found that vestiges of all three models lurked in the experience of providing connective labor, yet none fully captured the profound meaning practitioners reported finding in their work. Systems varied on three dimensions, reflecting the relative worth of worker, recipient or the work, extracting value from the forged connections, while the meanings workers derived shaped their perspective on its systematization.

The concept of constructive negation we refer to in this paper is (minimally) intuitionistic in character (see [1]). The idea is to understand the negation of a proposition A as equivalent to A implying a falsity constant of some sort. Then, negation is introduced either by means of this falsity constant or, as in this paper, by means of a propositional connective defined with the constant. But, unlike intuitionisitc logic, the type of negation we develop here is, of course, (...) devoid of paradoxes of relevance. (shrink)

We construct a a system PLRI which is the classical propositional logic supplied with a ternary construction , interpreted as the intensional identity of statements and in the context . PLRI is a refinement of Roman Suszko’s sentential calculus with identity (SCI) whose identity connective is a binary one. We provide a Hilbert-style axiomatization of this logic and prove its soundness and completeness with respect to some algebraic models. We also show that PLRI can be used to give a (...) partial solution to the paradox of analysis. (shrink)

This paper explores the different identities adopted by connective tissue research at the University of Manchester during the second half of the 20th century. By looking at the long-term redefinition of a research programme, it sheds new light on the interactions between different and conflicting levels in the study of biomedicine, such as the local and the global, or the medical and the biological. It also addresses the gap in the literature between the first biomedical complexes after World War (...) II and the emergence of biotechnology. Connective tissue research in Manchester emerged as a field focused on new treatments for rheumatic diseases. During the 1950s and 60s, it absorbed a number of laboratory techniques from biology, namely cell culture and electron microscopy. The transformations in scientific policy during the late 70s and the migration of Manchester researchers to the US led them to adopt recombinant DNA methods, which were borrowed from human genetics. This resulted in the emergence of cell matrix biology, a new field which had one of its reference centres in Manchester. The Manchester story shows the potential of detailed and chronologically wide local studies of patterns of work to understand the mechanisms by which new biomedical tools and institutions interact with long-standing problems and existing affiliations.

In the first part of this paper (Méndez and Robles 2008) a minimal and an intuitionistic negation is introduced in a wide spectrum of relevance logics extending Routley and Meyer's basic positive logic B+. It is proved that although all these logics have the characteristic paradoxes of consistency, they lack the K rule (and so, the K axiom). Negation is introduced with a propositional falsity constant. The aim of this paper is to build up logics definitionally equivalent to those in (...) the aforementioned paper, negation being now introduced with the unary connective. Relational ternary semantics are provided for the new logics and soundness and completeness results are proved. (shrink)

Collagen is the most abundant vertebrate protein and forms a stable fibrous architecture in connective tissues, such as bone, cartilage, skin and tendon. Much recent research has been directed towards an understanding of the molecular and cellular mechanisms involved in the synthesis and degradation of collagen, because a change in the normal balance, or an increased destruction of collagen, can cause loss of function of specialized tissues. This short review attempts to summarize present knowledge about the proteolytic destruction of (...) collagen and the exciting new work on the factors that are emerging as important controlling agents. An understanding of the regulatory processes is yielding some important clues regarding the levels at which they can fail in pathological conditions and we speculate about evolving strategies for preventing uncontrolled resorption.

In this book, the author presents a series of essays that demonstrate the power and versatility of connective, contrastive, and contextual analysis, a novel and original approach to philosophical inquiry. Drawing on themes from his acclaimed tetralogy on human nature, the author shows how to solve, resolve, and dissolve philosophical problems by connecting, contrasting, and contextualizing different concepts, perspectives, and arguments. The book covers a wide range of topics, from the nature of consciousness and experience, to the place of (...) value in a world of facts, to the problem of evil and the death of the soul. The book also includes a new essay on dreaming, as well as a comprehensive overview of the methodology of connective, contrastive, and contextual analysis. The book is written in an accessible and engaging style, with minimal technical jargon and no formal symbolism. It is suitable for anyone who is interested in philosophy and wants to learn how to think more clearly, creatively, and critically about philosophical problems. (shrink)

The Converse Ackermann Property is the unprovability of formulas of the form (A -> B) -> C when C does contain neither -> nor ¬. Intuitively, the CAP amounts to rule out the derivability of pure non-necessitive propositions from non-necessitive ones. A constructive negation of the sort historically defined by, e.g., Johansson is added to positive logics with the CAP in the spectrum delimited by Ticket Entailment and Dummett’s logic LC.

Collagen fibrils are some of the most‐abundant and important extracellular structures in our bodies, yet we are unsure of their shape and size. This is largely due to an inherent difficulty in isolating them from their surrounding tissues. Echinoderms have collagenous tissues that are similar to ours in many ways, yet they can be manipulated to easily relinquish their collagen fibrils, providing an excellent opportunity to study native fibrillar structure. In the early 1990s, they were found to defy the commonly (...) accepted fibrillar model of the time in that they were much shorter, they were shaped like double‐ended spindles, and their centers exhibited a reversal in molecular polarity. Realization of these features helped to reform the questions that were being asked about vertebrate fibrils, shifting the focus toward shape and size. Since then, researchers working with both groups (echinoderms and vertebrates) have worked together to find the structure of native fibrils. This information will be fundamental in understanding what holds collagenous tissues together at the fibrillar level, and could have important implications for people with Ehlers‐Danlos syndrome.

Perlecan is a ubiquitous proteoglycan of basement membrane and vascularized tissues but is also present in articular cartilage, meniscus and intervertebral disc, which are devoid of basement membrane and predominantly avascular. It is a prominent pericellular proteoglycan in the transitory matrix of the cartilaginous rudiments that develop into components of diarthrodial joints and the axial skeleton, and it forms intricate perichondrial vessel networks that define the presumptive articulating surfaces of developing joints and line the cartilage canals in cartilaginous rudiments. Such (...) vessels have roles in the nutrition of the expanding cell numbers in the developing joint. Perlecan sequesters a number of growth factors pericellularly (FGFs, PDGF, VEGF and CTGF) and through these promotes cell signalling, cell proliferation and differentiation. Perlecan also interacts with a diverse range of extracellular matrix proteins, stabilising and organising the ECM, and promoting collagen fibrillogenesis. Perlecan is a prominent pericellular component of mesenchymal cells from their earliest developmental stages through to maturation, forming cell–cell and cell–ECM interconnections that are suggestive of a role in mechanosensory processes important to tissue homeostasis.

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)

The pull to coordinate with other individuals is fundamental, serving as the basis for our social connectedness to others. Discussed is a dynamical and ecological perspective to joint action, an approach that embeds the individual’s mind in a body and the body in a niche, a physical and social environment. Research on uninstructed coordination of simple incidental rhythmic movement, along with research on goal‐directed, embodied cooperation, is reviewed. Finally, recent research is discussed that extends the coordination and cooperation studies, examining (...) how synchronizing with another, and how emergent social units of perceiving and acting are reflected in people’s feelings of connection to others.

There are certain uses of and and or that cannot be explained by their normal meanings as truth-functional connectives, even with sophisticated pragmatic resources. These include examples such as The cops show up, and a fight will break out (‘If the cops show up, a fight will break out’), and I have no friends, or I would throw a party (‘I have no friends. If I did have friends, I would throw a party.’). We argue that these uses are indeed (...) distinct from the more ordinary uses of and and or, but that they are nonetheless related in a principled way. To explain them we give an analysis of what we call the dynamic effects of connectives, which arise in all their uses. The special uses at issue are then argued to be instances where the connectives exhibit their dynamic effects without their truth-conditional meaning. (shrink)

Networks pervade social and economic life, and they play a prominent role in explaining a huge variety of social and economic phenomena. Standard economic theory did not give much credit to the role of networks until the early 1990s, but since then the study of the theory of networks has blossomed. At the heart of this research is the idea that the pattern of connections between individual rational agents shapes their actions and determines their rewards. The importance of connections has (...) in turn motivated the study of the very processes by which networks are formed. In Connections, Sanjeev Goyal puts contemporary thinking about networks and economic activity into context. He develops a general framework within which this body of research can be located. In the first part of the book he demonstrates that location in a network has significant effects on individual rewards and that, given this, it is natural that individuals will seek to form connections to move the network in their favor. This idea motivates the second part of the book, which develops a general theory of network formation founded on individual incentives. Goyal assesses the robustness of current research findings and identifies the substantive open questions. Written in a style that combines simple examples with formal models and complete mathematical proofs, Connections is a concise and self-contained treatment of the economic theory of networks, one that should become the natural source of reference for graduate students in economics and related disciplines.

This paper aims to connect philosophy of chemistry, green chemistry, and moral philosophy. We first characterize chemistry by underlining how chemists: co-define chemical bodies, operations, and transformations; always refer to active and context-sensitive bodies to explain the reactions under study; and develop strategies that require and intertwine with a molecular whole, its parts, and the surroundings at the same time within an explanation. We will then point out how green chemists are transforming their current activities in order to act upon (...) the world without jeopardizing life. This part will allow us to highlight that green chemistry follows the three aforementioned characteristics while including the world as a partner, as well as biodegradability and sustainability concerns, into chemical practices. In the third part of this paper, we will show how moral philosophy can help green chemists: identify the consequentialist assumptions that ground their reasoning; and widen the scope of their ethical considerations by integrating the notion of care and that of vulnerability into their arguments. In the fourth part of the paper, we will emphasize how, in return, this investigation could help philosophers querying consequentialism as soon as the consequences of chemical activities over the world are taken into account. Furthermore, we will point out how the philosophy of chemistry provides philosophers with new arguments concerning the key debate about the ‘intrinsic value’ of life, ecosystems and the Earth, in environmental ethics. To conclude, we will highlight how mesology, that is to say the study of ‘milieux’, and the concept of ‘ecumeme’ proposed by the philosopher and geographer Augustin Berque, could become important both for green chemists and moral philosophers in order to investigate our relationships with the Earth.

When physicist Alan Sokal recently submitted an article to the postmodernist journal Social Text, the periodical's editors were happy to publish it--for here was a respected scientist offering support for the journal's view that science is a subjective, socially constructed discipline. But as Sokal himself soon revealed in Lingua Franca magazine, the essay was a spectacular hoax--filled with scientific gibberish anyone with a basic knowledge of physics should have caught--and the academic world suddenly awoke to the vast gap that has (...) opened between the scientific community and their mould-be critics. But the truth is that not only postmodern critics but Americans in general have a weak grasp on scientific principles and facts. In Connected Knowledge, physicist Alan Cromer offers a way to bridge the chasm, with a lively, lucid account of scientific thinking and a provocative new agenda for American education. Science, Cromer argues, is anything but common sense: It requires a particular habit of mind that does not come naturally. For example, something as simple as buoyancy can only be explained through Archimedes' principle--that a body in a fluid is subject to an upward force equal to the weight of fluid it displaces--yet few scientists could arrive at this ancient concept by trial and error. School children, however, are often given a ball and a tank of water, and asked to explain buoyancy any way they can. Today's de emphasis on teaching pupils necessary facts and principles, he argues, "far from empowering them, makes them slaves of their own subjective opinions." This movement in education, known as Constructivism, has close ties to postmodern critics (such as the editors of Social Text) who question the objectivity of science, and with it the existence of an objective reality. Cromer offers a ringing defense of the knowability of the world, both as an objective reality and as a finite landscape of discovery. The advance of scientific knowledge, he argues, is not unlike the mapping of the continents; at this point, we have found them all. He shows how the advent of quantum mechanics, rather than making knowledge less certain, actually offers a more precise understanding of the behavior of atoms and electrons. Turning from philosophy to education, he argues that instead of allowing students to flounder, however creatively, schools should follow a progressive curriculum that returns theoretical knowledge to the classroom. Connected Knowledge, however, goes much farther. As a discipline that insists upon connecting theory with measurable reality, physical science offers a new direction for reforming the social sciences. Cromer also shows how some of the hottest issues in public policy--including the debates over special education and group variations in I.Q., can be resolved through clear, hard headed thinking. For example, he argues for use of the G.E.D. as a national educational standard, with a new "politics of intelligence" to guide the distribution of school resources. Always forthright and articulate, Alan Cromer offers a startling new vision for integrating science, philosophy, and education. (shrink)

Abstract:This essay explores the concept of the connected self-owner, which takes account of the metaphysical significance of relations among persons for persons’ capacities to be owners. This concept of the self-owner conflicts with the traditional libertarian understanding of the self-owner as atomistic or essentially separable from all others. I argue that the atomistic self cannot be a self-owner. A self-owner is a moral person with intentions, desires, and thoughts. But in order to have intentions, desires, and thoughts a being must (...) relate to others through language and norm-guided behavior. Individual beings require the pre-existence of norms and norm-givers to bootstrap their selves, and norms, norm-givers, and norm-takers are necessary to continue to support the self. That means, I argue, that the self who can be an owner is essentially connected. Next, I ask how humans become connected selves and whether that connection matters morally. I distinguish among those connections that support development of valuable capacities. One such capacity is the autonomous individual. I argue that the social connections that allow the development of autonomous individuals have moral value and should be fostered. On the basis of these two values, I argue that we can support at least two nonvoluntary obligations, one negative and one positive, that we can ground in our metaphysical essence as connected self-owners.
