In this paper, we present an intensive investigation of the finite volume method compared to the finite difference methods. In order to show the main difference in the way of approaching the solution, we take the Burgers equation and the Buckley–Leverett equation as examples to simulate the previously mentioned methods. On the one hand, we simulate the results of the finite difference methods using the schemes of Lax–Friedrichs and Lax–Wendroff. On the other hand, we apply Godunov’s scheme to simulate (...) the results of the finite volume method. Moreover, we show how starting with a variational formulation of the problem, the finite element technique provides piecewise formulations of functions defined by a collection of grid data points, while the finite difference technique begins with a differential formulation of the problem and continues to discretize the derivatives. Finally, some graphical and numerical comparisons are provided to illustrate and corroborate the differences between these two main methods. (shrink)

The current discussions of conceptual schemes and related topics are misguided; for they have been focused too much on the truth-conditional notions of meaning/concepts and translation/interpretation in Tarski's style. It is exactly due to such a Quinean interpretation of the notion of conceptual schemes that the very notion of conceptual schemes falls prey to Davidson's attack. We argue that what should concern us in the discussions of conceptual schemes and related issues, following (...) the initiatives of I. Hacking, T. Kuhn, and N. Rescher, is not the truth-values of assertions, but rather the truthvalue-status of the sentences used to make the assertions. This is because the genuine conceptual innovation between alternative theories/languages does not lie in differences in determining the truth-values of their sentences, but turns on whether these sentences have truth-values when considered within the context of a competing one. The core of conceptual relativism does not consist in the claim that different conceptual schemes may yield incommensurable truth claims, but rather that different conceptual schemes may yield incompatible truth-value-status and therefore lead to distinct perceptions of reality. Conceptual schemes are no longer seen as sentential languages consisting of a set of sentences accepted as true, but rather seen as metaphysical presuppositions of presuppositional languages.[ABSTRACT FROM AUTHOR].

In this paper the complex phenomenon of pain is discussed and analysed along different theoretical paths: cognitivism, hermeneutics, phenomenology. The neuro-cognitive approach is exemplified through Paul and Patricia Churchland’s writings; then H.-G. Gadamer’s hermeneutical approach is evaluated. While apparently opposite, they share a common assumption, namely that the body is basically to be conceived of as not really different from the Cartesian Res extensa. Some problems thus arise: in particular, the aspect of reflexivity implied in any experience of (...) pain is overlooked. Accordingly, an adequate approach to feeling pain must take the phenomenological path. This means to discuss Husserl’s but also Scheler’s and Heidegger’s contributions, in order to bring to the fore the complexity of the phenomenon of pain, which shows a particular and paradoxical structure: exposing the subject feeling pain to its own internal exteriority.

Generic noun phrases (e.g. 'bats live in caves') provide a window onto human concepts. They refer to categories as 'kinds rather than as sets of individuals. Although kind concepts are often assumed to be universal, generic expression varies considerably across languages. For example, marking of generics is less obligatory and overt in Mandarin than in English. How do universal conceptual biases interact with language-specific differences in how generics are conveyed? In three studies, we examined adults' generics in English and (...) Mandarin Chinese. The data include child-directed speech from caregivers interacting with their 19-23-month-old children. Examples of generics include: 'baby birds eat worms' (English) and da4 lao3shu3 yao3 bu4 yao3 ren2 ('do big rats bite people or not?') (Mandarin). Generic noun phrases were reliably identified in both languages, although they occurred more than twice as frequently in English as in Mandarin. In both languages, generic usage was domain-specific, with generic noun phrases used most frequently to refer to animals. This domain effect was specific to generics, as non-generic noun phrases were used most frequently for artifacts in both languages. In sum, we argue for universal properties of 'kind' concepts that are expressed with linguistically different constructions. However, the frequency of expression may be influenced by the manner in which generics are expressed in the language. (shrink)

It has become very popular among philosophers to attempt to discredit, or at least set severe limits to, the thesis that there exist conceptual schemes radically different from ours. This fashion is misconceived. Philosophers have attempted to justify it in two main ways: by means of arguments which are a priorist relative to the relevant linguistic and textual evidence (and either independent of or based upon positive theories of meaning, understanding, and interpretation); and by means of arguments (...) which are a posteriorist relative to that evidence. The former approach is misconceived, not only in that its particular arguments fail, but also in principle. The latter approach, while in general the right sort of approach to adopt to the question, arrives at its conclusion only through faulty execution, through misinterpretation of the evidence. Though quite unjustified, philosophers' hostility to the thesis of radically different conceptual schemes is easily explained, namely, in terms of a number of psychologically powerful motives which it subserves. These motives cannot step in to provide the missing justification, however. Instead, they reveal such hostility in an even shadier light. (shrink)

The issue of interpersonal comparisons of utility is about the possibility (or not) of comparing the utility or welfare or the mental states in general, of different individuals. Embedded in the conceptual framework of utilitarianism, interpersonal comparisons were admissible in economics as part of the theoretical justification of welfare policies until the first decades of the twentieth century. Under the strong influence of the scientific philosophy of positivism as reflected in the works of early neoclassical economists and as (...) epitomized by Lionel Robbins, utility comparisons were subsequently rejected as a value judgement. Robbins’ methodological stance is still prevalent among mainstream economists. Despite the explicit rejection of comparability by the majority of economists, interpersonal comparisons are necessary for many key policy issues, such as progressive taxation, social welfare policies, GDP-based welfare comparisons, cost–benefit analysis, and public goods provision. In this paper, the case of interpersonal utility comparisons is discussed as an illustrative example of the usefulness of the study of the role of value judgements, and generally of the interrelationship between ethics and economics. It is argued that the current tension between theory and policy practice might be resolved through the efforts of prominent economists and philosophers to challenge positivism, and especially its problematic treatment of value judgements and of ethical assumptions in general. The discussion also provides more strength to the view that policy makers and their economic advisers cannot avoid ethical questions in their analysis of the workings of the economic system.

This paper discusses some of the ways in which Martin-Löf type theory differs from set theory. The discussion concentrates on conceptual, rather than technical, differences. It revolves around four topics: sets versus types; syntax; functions; and identity. The difference between sets and types is spelt out as the difference between unified pluralities and kinds, or sorts. A detailed comparison is then offered of the syntax of the two languages. Emphasis is placed on the distinction between proposition and judgement, (...) drawn by type theory, but not by set theory. Unlike set theory, type theory treats the notion of function as primitive. It is shown that certain inconveniences pertaining to function application that afflicts the set- theoretical account of functions are thus avoided. Finally, the distinction, drawn in type theory, between judgemental and propositional identity is discussed. It is argued that the criterion of identity for a domain cannot be formulated in terms of propositional identity. It follows that the axiom of extensionality cannot be taken as a statement of the criterion of identity for sets. (shrink)

Ontology has been proposed as a solution to the 'Tower of Babel' problem that threatens the semantic interoperability of information systems constructed independently for the same domain. In information systems research and applications, ontologies are often implemented by formalizing the meanings of words from natural languages. However, words in different natural languages sometimes subdivide the same domain of reality in terms of different conceptual categories. If the words and their associated concepts in two natural languages, or even (...) in two terminological traditions within the same language, do not have common referents in the real world, an ontology based on word meanings will inherit the 'Tower of Babel' problem from the languages involved, rather than solve it. In this paper we present evidence from a preliminary comparison of landscape terms in English with those in the Yindjibarndi language of northwestern Australia demonstrating that this problem is not just hypothetical. Some possible solutions are suggested. (shrink)

Given that health systems research involves different aims, approaches, and methodologies as compared to more traditional clinical trials, the ethical issues present in HSR may be unique or particularly nuanced. This article outlines eight pertinent ethical issues that are particularly salient in HSR and argues that the ethical review process should be better tailored to ensure more efficient and appropriate oversight of HSR with adequate human protections, especially in low- and middle-income countries. The eight ethical areas we discuss include (...) the nature of intervention, types of research subjects, units of intervention and observation, informed consent, controls and comparisons, risk assessment, inclusion of vulnerable groups, and benefits of research. HSR involving human participants is necessary to ensure health systems strengthening and quality of care and to guide public policy intelligently. Health systems researchers must carefully define their intent and goals and openly clarify the values that may influence the premises and design of protocols. As new types of population-level research activities become more commonplace, it is critical that institutional review board and research ethics committee review processes evolve to evaluate these research protocols in ways that address the nuanced features of these studies.

Physical superpositions exist both in classical and in quantum physics. However, what is exactly meant by ‘superposition’ in each case is extremely different. In this paper we discuss some of the multiple interpretations which exist in the literature regarding superpositions in quantum mechanics. We argue that all these interpretations have something in common: they all attempt to avoid ‘contradiction’. We argue in this paper, in favor of the importance of developing a new interpretation of superpositions which takes into account (...) contradiction, as a key element of the formal structure of the theory, “right from the start”. In order to show the feasibility of our interpretational project we present an outline of a paraconsistent approach to quantum superpositions which attempts to account for the contradictory properties present in general within quantum superpositions. This approach must not be understood as a closed formal and conceptual scheme but rather as a first step towards a different type of understanding regarding quantum superpositions. (shrink)

The purpose of the dissertation is to defend and elaborate on internal realism, a doctrine first put forward by Hilary Putnam. Chapter 1 surveys the current philosophical conceptions of truth and reference, a necessary background for the ensuing discussion. Chapter 2 explains the metaphysical realism vs. internal realism controversy. Internal realism is construed as consisting of three theses: the ontological mind-dependence of the world, verificationism about truth , and conceptual relativism . Chapter 3 offers an internal realist account of (...) reference. The key idea is that the references of words get fixed by justification conditions of sentences. It also discusses Putnam's controversial Twin Earth and model-theoretic arguments. These arguments might seem to pull into different directions, but they can be reconciled, and they fit well with the internal realist account. Chapter 4 presents an internal realist account of truth. Within a conceptual scheme, given the reference of words, truth can be defined by Tarkis's method. Conceptual schemes themselves are adequate if they can support a choiceworthy and successful practice. It is also shown--through an analysis of Putnam's brains-in-a-vat argument--that internal realism leaves no room for global skepticism. Chapter 5 defends the much maligned notion of conceptual scheme. It is argued that the analytic-synthetic and the observational-theoretical distinctions, which provided its basis, can be revised so that the familiar criticism are rendered harmless. The key idea is that the distinctions are relative to the perspective of an interpreter. The revised notion of conceptual scheme can also withstand Davidson's attack and other frequent objections.

Based on our empirical research on global meaning in people with spinal cord injury and people with stroke, we formulated ‘inner posture’ as a concept in rehabilitation. Inner posture, as we concluded from our empirical data, refers to the way in which people bear what cannot be changed. It helps them to live with their injury. Considering that much has already been written about meaning from a variety of disciplines, the question arises whether the concept of inner posture adds something (...) new to the existing literature, or is just another name for a phenomenon that has already been described before in different terms. In this paper, we aim to investigate this and to clarify our conceptualization, by comparing the concept of inner posture with influential concepts in healthcare literature which seem to be more or less related. In the work of Puchalski regarding spirituality, Pargament regarding religion, Eliott regarding hope and Frankl regarding attitude, we found definitions and descriptions that seemed to come close to the phenomenon we refer to as inner posture. Because these concepts have various theoretical backgrounds, the comparison can help to better understand our concept of inner posture, through a process of dialogue between traditions, following Gadamer’s notion of dialogue as fusion of horizons of understanding. We conclude that inner posture differs from the other concepts in several ways. Some of these differences are more fundamental, other are partial. This suggests that we identified a new perspective on a phenomenon partially described earlier. The comparison also inspired us to slightly adjust our definition and to formulate new research questions. (shrink)

We considered the question of how corporate social responsibility differs between Canada and the U.S. Prior research has identified that national institutional differences exist between the two countries [Freeman and Hasnaoui, J Business Ethics 100:419–443, 2011], which may be associated with variations in their respective CSR practices. Matten and Moon [Acad Manag Rev 33:404–424, 2008] suggested that cross-national differences in firms’ CSR are depicted by an implicit–explicit conceptual framework: explicit CSR practices are deliberate and more strategic than implicit CSR (...) practices. We compared Canada and U.S. CSR and examined how CSR strategic alliances, CSR reporting, and CSR performance in the two countries correspond to implicit versus explicit CSR practices, which we link to stakeholder and signaling perspectives. We relied upon a new database, the Sustainalytics Global Platform, and we found a positive association exists between CSR strategic alliances and the number of years that firms have issued standalone CSR reports in both countries. Moreover, we found that CSR scores mediated this association in the U.S., as U.S. firms with high CSR scores typically engage in more CSR strategic alliances. In Canada, we did not find this mediating effect. Our findings suggest that U.S. firms engage in signaling activities that are more strategic and explicit than their Canadian counterparts. This paper closes with implications for practice and theory. (shrink)

The generalization of Complementarity has been an ambition and a challenge to many a Bohrian scholar or quantum philosopher, and to Bohr himself above all others besides. A very recent attempt by Professor Gonzalo Munevar, proposing an extension of CTY to alternative conceptual schemes, re-opens this issue and seeks to place it within the context of modern day Relativism on the grounds that conceptual schemes belonging to different cultural groups or even different biological species (...) are neither reducible to one another, nor equivalent, nor however contradictory and therefore simply "complementary." Such being the case, neither conceptual scheme can overrule its rival scheme, nor however include or assimilate it, being to all intents and purposes as valid as its rival, albeit fundamentally divergent from it. This conclusion inevitably guides the steps of knowledge along the path of Relativism and Subjectivism, a route which Prof. Munevar makes it perfectly clear that he would eagerly follow. (shrink)

This work uses microgenetic study of classroom learning to illuminate (1) the role of pre-instructional student knowledge in the construction of normative scientific knowledge, and (2) the learning mechanisms that drive change. Three enactments of an instructional sequence designed to lead to a scientific understanding of thermal equilibration are used as data sources. Only data from a scaffolded student inquiry preceding introduction of a normative model were used. Hence, the study involves nearly autonomous student learning. In two classes, students developed (...) stable and socially shared explanations (“causal schemes”) for understanding thermal equilibration. One case resulted in a near-normative understanding, while the other resulted in a non-normative “alternative conception.” The near-normative case seems to be a particularly clear example wherein the constructed causal scheme is a composition of previously documented naïve conceptions. Detailed prior description of these naive elements allows a much better than usual view of the corresponding details of change during construction of the new scheme. A list of candidate mechanisms that can account for observed change is presented. The non-normative construction seems also to be a composition, albeit of a different structural form, using a different (although similar) set of naïve elements. This article provides one of very few high-resolution process analyses showing the productive use of naïve knowledge in learning. (shrink)

The current discussions of conceptual schemes and related topics are misguided; for they are based on a tacit assumption that the difference between two schemes consists in the different distributions in truth-values. I argue that what should concern us, in the discussions of conceptual schemes and related issues, is not truth-values of assertions, but rather the truth-value-status of the sentences used to make the assertions. This is because the genuine conceptual innovation between alternative (...) theories or languages does not lie in differences in determining truth-values of their sentences, but turns on whether these sentences have truth-values when considered within the context of a competing one. This new interpretation of the notion of conceptual schemes, which I refer to as presuppositional languages, is not only good in itself—for establishing the intelligibility and tenability of the notion—but quite beneficial in its effect on other related issues.

One of the most challenging tasks when adopting Bayesian networks is the one of learning their structure from data. This task is complicated by the huge search space of possible solutions and by the fact that the problem isNP-hard. Hence, a full enumeration of all the possible solutions is not always feasible and approximations are often required. However, to the best of our knowledge, a quantitative analysis of the performance and characteristics of the different heuristics to solve this problem (...) has never been done before. For this reason, in this work, we provide a detailed comparison of many different state-of-the-art methods for structural learning on simulated data considering both BNs with discrete and continuous variables and with different rates of noise in the data. In particular, we investigate the performance of different widespread scores and algorithmic approaches proposed for the inference and the statistical pitfalls within them. (shrink)

In this paper, I argue that established responses to the demandingness objection fail to acknowledge an alternative explanation of the intuitive pull of this objection for a significant subset of norms being subject to it. This is the class of imperfect collective duties, which give rise to conceptually distinct objections from fairness that nonetheless permeate many clear examples of intuitively problematic moral demands. Such duties obtain where it is morally required to attain a certain outcome O, yet obtaining O does (...) not require each moral agent to do as much as they individually can but instead requires a finite amount of effort that can be variously allocated to different agents – think of classic collective action problems such as protesting against an unjust policy, lobbying a government, donating to disaster relief, or hosting refugees. -/- In such cases, our collective ability to attain O grounds a collective duty C to attain O, but this collective duty can be translated into various schemes of individual duties P to contribute towards O. Accordingly, this decomposition of C raises a problem of distributive justice. In fact, many intuitive objections to unfair distributions in such cases can be readily accounted for with the conceptual apparatus of prominent theories of distributive justice, but not by standard theories of interpersonal morality. For instance, the moral relevance of the fact that performing a composite duty P is more burdensome for agent A than for agent B can readily be explained in luck-egalitarian terms. Yet both utilitarians and contractualists could not account for this fact independently of an appeal to the demandingness objection, provided that the moral importance of the outcome attainable through P still trumps reasons against it that are due to the burden borne by the agent. -/- Put briefly, then, we need to clearly distinguish objections that morality demands _too much_ of me from objections that morality demands too much _of me_. Doing so is likely to make accepting the demandingness of morality properly construed more intuitively plausible, perhaps as mitigated by certain existing responses. (shrink)

In recent times it has become fashionable to emphasize the role of conceptual change in the history of science. To judge from recent writers, every significant theoretical change in science is first and foremost a revolution in scientific concepts—a conceptual revolution. According to this view, every level of experience is affected by each fundamental theoretical change: physical theory, experimental practice and even perceptual experience. The Aristotelian patrician who watched the sun sink beneath the horizon not only had (...) class='Hi'>different beliefs about the phenomenon but actually saw something different from the Newtonian gentleman who saw the horizon rise above his eye-sun line, and the Einsteinian professional who saw the sun's varying geometrical relations to the world light-geodesics on which successive temporal stages of his eye world-line lay. Moreover, such is the completeness of the conceptual-experiential shifts undergone in a fundamental scientific change that it is impossible to meaningfully discuss the one theory within the confines of the other or, indeed, to provide any systematic, cumulative comparison of successive theories.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Picturing Hegel: An Illustrated Guide to Hegel’s Encyclopaedia LogicJames A. Dunson IIIJulie E. Maybee. Picturing Hegel: An Illustrated Guide to Hegel’s Encyclopaedia Logic. Lanham, MD: Lexington Books, 2009. Pp. xxvii + 639. Paper, $56.95.If Hegel were alive to read an illustrated guide to his Encyclopaedia Logic, he might not immediately appreciate the project. Not only did he consider “picture-thinking” deficient in comparison to conceptual thinking, but (...) he regarded the Encyclopaedia Logic as a text suitable for German students. In her recent book, Picturing Hegel, Julie Maybee acknowledges these ironies and proceeds to guide those of us who need a little extra help in understanding Hegel’s speculative logic.What results is a significant contribution to the literature, a step-by-step commentary [End Page 536] through one of Hegel’s most underappreciated works. Using diagrams to cut through the often-difficult prose proves to be an excellent strategy. Maybee’s exquisitely detailed and admirably clear exposition makes her a suitable Virgil to guide us through the Inferno of Hegel’s logic.Maybee’s task is to show how Hegel’s logic is, actually, logical, and not, as she puts it, “A jumble of random moves from one step to the next” (xiii). She distinguishes Hegel’s speculative logic from the logic we teach nowadays by emphasizing Hegel’s concern to generate and develop the concepts he employs. That is, he is concerned not merely with the rules connecting the logical terms (i.e. syntax), but also the meanings of the terms themselves (i.e. semantics).As one might expect, these concepts are developed dialectically: two elements that are ordinarily opposed to one another are revealed to be mutually defining and interdependent. Readers already familiar with Hegel’s work will appreciate the way in which Maybee explains complicated ideas like “Actuality” and “spurious infinity.” Maybee has a talent for inventive examples, some of which she carefully carries through the entire work. Also, she has an eye for Hegel’s own examples (see, for instance, the comparison of the Absolute Idea and an old man on 580–82).One of the chief merits of her detailed account is its balanced approach. Instead of perpetuating prevalent but superficial interpretations, she explains the different senses in which something is true. For instance, she distinguishes the different meanings of idealism and shows how Hegel retains some materialist elements in his logic (302). Her knowledge of the history of philosophy helps her to put Hegel’s logic in its proper context. The asides to the Pre-Socratic philosophers and the repeated references to Kant are especially useful.Maybee’s approach to the logic, especially the way in which she frames Hegel’s project, raises interesting philosophical questions. She portrays Hegel as attempting to overcome Kant’s skepticism regarding the unity of thought and being. The question is whether reality is fundamentally accessible to reason, or whether the categories we employ to understand the world are limited to our phenomenal experience.But if Hegel’s logic is supposed to refute the Kantian “thing-in-itself,” we can ask whether this is an intelligible philosophical goal. First, Maybee points out that critics like Nietzsche would ask whether we have to be “committed to logical or conceptual necessity” (130). Perhaps Hegel exhibits a rather typical philosophical bias toward conceptual stability and even necessity. Second, any investigation into logical semantics that is biased in this way inevitably opens Pandora’s Box. Determining the meaning of logical terms is a messy business, and Hegel sometimes seems to stipulate meanings instead of genuinely deriving them. For instance, as Maybee writes, a crucial part of Hegel’s definition of existence is that something is “capable of being experienced” (204). But this simply begs the question against Kant’s “thing-in-itself,” since clearly Kant does not think it exists in this way.Third, given that Maybee points out Hegel’s anthropocentric language, we can ask whether his casual and frequent references to human experience are innocent or self-undermining. For instance, what are we to make of Hegel’s use of ethical examples to explain logical concepts like actuality, necessity, and possibility? A Kantian might... (shrink)

It seems at least daring to speak of truth on the subject of art, when Plato, in the Sophiste, 234c, likens art to sophistry, in other words, to falsity and deformation. To be sure, this comparison is based on an exaggeration, because elsewhere Plato insists on the necessity of artistic reality: in the same Sophiste, 299e, he states that “life would be unlivable without art.” The importance thus given to art becomes obvious when we think that this same expression (...) is already used in the Apologie, 38a, with regard to philosophy, the activity that for a man conscious of his own existence is one of scrupulously examining his own life. This similarity in expression testifies to the conceptual and axiological similarity of two (but distinct) activities of the mind effected by Plato who, on a different level, as we have just seen, unhesitatingly condemns one of them, at least apparently; apparently, because basically Plato does not inveigh against art in general but against the art of his contemporaries, whom he openly accuses of accepting the postulate of verisimilitude by using artifice and acrobatics, with the sole end of pleasing the crowds by flattery. In other words, they substitute for the scarch for authenticity that of dexterity in creations conceived only for that effect, which means identifying this type of substitution of values with a prostitution of the artist himself with regard to his public.

Examining variation in reasoning about sustainability between diverse populations provides unique insight into how group norms surrounding resource conservation develop. Cultural institutions, such as religious organizations and formal schools, can mobilize communities to solve collective challenges associated with resource depletion. This study examined conservation beliefs in a Western industrialized (Austin, Texas, USA) and a non‐Western, subsistence agricultural community (Tanna, Vanuatu) among children, adolescents, and adults (N = 171; n = 58 7–12‐year‐olds, n = 53 13–17‐year‐olds, and n = 60 18–68‐year‐olds). (...) Participants endorsed or rejected four types of justifications for engaging in land and animal conservation: sustainability, moral, religious, or permissible. In both populations, participants endorsed sustainability justifications most frequently. Religious justifications increased with age in Tanna and decreased with age in Austin. Tannese participants were also more likely to endorse multiple justifications for conservation than Austin participants. Data across all justification types show a main effect of age in both communities; endorsement of conservation decreased with age in Austin, but increased with age in Tanna. Across age groups, participants were more likely to endorse the conservation of animals than land in Austin, yet equally as likely to endorse the conservation of land and animals in Tanna. Overall, these results reveal similarities and differences in the beliefs that support the conservation of natural resources across populations. (shrink)

This article aims to contribute to the literature on conceptual change by engaging in direct theoretical and empirical comparison of contrasting views. We take up the question of whether naïve physical ideas are coherent or fragmented, building specifically on recent work supporting claims of coherence with respect to the concept of force by Ioannides and Vosniadou [Ioannides, C., & Vosniadou, C. (2002). The changing meanings of force. Cognitive Science Quarterly 2, 5–61]. We first engage in a theoretical inquiry (...) on the nature of coherence and fragmentation, concluding that these terms are not well‐defined, and proposing a set of issues that may be better specified. The issues have to do with contextuality, which concerns the range of contexts in which a concept (meaning, model, theory) applies, and relational structure, which is how elements of a concept (meaning, model, or theory) relate to one another. We further propose an enhanced theoretical and empirical accountability for what and how much one needs to say in order to have specified a concept. Vague specification of the meaning of a concept can lead to many kinds of difficulties.Empirically, we conducted two studies. A study patterned closely on Ioannides and Vosniadou's work (which we call a quasi‐replication) failed to confirm their operationalizations of “coherent.” An extension study, based on a more encompassing specification of the concept of force, showed three kinds of results: (1) Subjects attend to more features than mentioned by Ioannides and Vosniadou, and they changed answers systematically based on these features; (2)We found substantial differences in the way subjects thought about the new contexts we asked about, which undermined claims for homogeneity within even the category of subjects (having one particular meaning associated with “force”) that best survived our quasi‐replication; (3) We found much reasoning of subjects about forces that cannot be accounted for by the meanings specified by Ioannides and Vosniadou. All in all, we argue that, with a greater attention to contextuality and with an appropriately broad specification of the meaning of a concept like force, Ioannides and Vosniadou's claims to have demonstrated coherence seem strongly undermined. Students' ideas are not random and chaotic; but neither are they simply described and strongly systematic. (shrink)

Notoriously, the Einstein equations of general relativity have solutions in which closed timelike curves occur. On these curves time loops back onto itself, which has exotic consequences: for example, traveling back into one's own past becomes possible. However, in order to make time travel stories consistent constraints have to be satisfied, which prevents seemingly ordinary and plausible processes from occurring. This, and several other "unphysical" features, have motivated many authors to exclude solutions with CTCs from consideration, e.g. by conjecturing a (...) chronology protection law. In this contribution we shall investigate the nature of one particular class of exotic consequences of CTCs, namely those involving unexpected cases of indeterminism or determinism. Indeterminism arises even against the backdrop of the usual deterministic physical theories when CTCs do not cross spacelike hypersurfaces outside of a limited CTC-region|such hypersurfaces fail to be Cauchy surfaces. We shall compare this CTC-indeterminism with four other types of indeterminism that have been discussed in the philosophy of physics literature: quantum indeterminism, the indeterminism of the hole argument, non-uniqueness of solutions of differential equations and lack of predictability due to insuffcient data. By contrast, a certain kind of determinism appears to arise when an indeterministic theory is applied on a CTC: things cannot be different from what they already were. Again we shall make comparisons, this time with other cases of determination in physics. We shall argue that on further consideration both this indeterminism and determinism on CTCs turn out to possess analogues in other, familiar areas of physics. CTC- indeterminism is close to the epistemological indeterminism we know from statistical physics, while the "fixedness" typical of CTC-determinism is pervasive in physics. CTC- determinism and CTC-indeterminism therefore do not provide incontrovertible grounds for rejecting CTCs as conceptually inadmissible. (shrink)

Currently, new business models created in the sharing economy differ considerably and they differ in the formation of trust as well. If and how trust can be created is shown by a comparison of two examples which diverge in their founding philosophy. The chosen example of community-based economy, Community Supported Agriculture (CSA), no longer trusts the capitalist system and therefore distances itself and creates its own environment including a new business model. It is implemented within rather small groups where (...) trust is created by personal relations and face-to-face communication. On the contrary, the example of a platform economy, the accommodation-provider company Airbnb, shows trust in the system and pushes technological innovations through the use of platform applications. It promotes trust and confidence in the progress of technology. For the conceptual analysis, the distinction between personal trust and system trust defined by Niklas Luhmann is adopted. The analysis describes two different modes of trust formation and how they push distrust or improve trust. Grounded on these analyses, assumptions on the process of trust formation within varying models of the sharing economy are formulated as well as a hypothesis about possible developments is introduced for further research.

Phenomenon of transdisciplinarity was put into the fore of analysis rather recently. In the article an attempt is made to find out whether it is possible to attribute this phenomenon not only to a science of the 21st century, or we have here the case where some scientific realities come to the attention of researchers with certain delay and has its value for the culture in general? It is possible to judge even the emergence of a kind of cognitive revolution (...) affecting both science culture. We need to find out what is meant by a transdisciplinarity, and how it differs from the inter- or multiransdisciplinarity. In the study the method of historical reconstruction, combining elements of presentism and antiqurism, was implemented. This method allows us to interpret historical events in the context of a specific level of knowledge, and at the same time to evaluate them in terms of modern ideas related to transdisciplinarity, inter- and multidisciplinarity. System-structural method, focused on an integrated analysis of the dynamics of development of cognitive processes in culture was implied as well, and the method of comparative analysis, which is aimed at comparing different but conceptually similar processes in various areas of conceptual art practice. It is in the framework of paradigm adopted a tacit agreement among scientists about the validity and effectiveness of research methods and techniques of inquiry. Within the paradigm, which presupposes certain fundamental principles, goals, and certain values shared by the scientific community, the novel sprouts of radical ideas once emerge. The scientific revolution here means a radical revision of the admissibility of accepted and proven methods, goals and values that are common to the members of the scientific community. Typically, new theories and concepts proposed and already mastered new scientific community, which is gradually replacing its representatives on the key command altitudes. The kernel of scientific community in fact is a style of thinking that is emerged in the context of a particular discipline, and then experience expansion in the form of discursive practices at a wide space of science and culture due to the novel cognitive schemes open the way to synthesize various research domains into a certain integrity. There is no question of the scientific revolution in the sense of Kuhn, since any significant goals and values of the scientific communities are not affected. Nevertheless, in some sense cognitive revolution taking place, the revolution of transdisciplinary type. The adoption of a new style of scientific thinking often gives rise to new types of objects and directions of cognitive activity, a new type of explanation that require new types of research proposals and cultural activities. Thus, the main idea of this article is that along with the Kuhn type scientific revolutions, transdisciplinary type scientific revolutions are conceivable, and even transdisciplinary cognitive types. This revolutions manifests in a change in style of reasoning, and it results in the expansion of this style to wide space of science and culture through the cognitive schemes and techniques, which enables to synthesize research and art activity in some integrity. Adoption of a new way of reasoning and the transition to new discursive practices generates new types of research facilities, new mechanisms of explanation, new cultural blueprints and instruments. Cognitive activity, based on a new style of thinking, involves multidisciplinarity, formation of new scientific and cultural institutions, and, therefore, causes a noticeable social change. Based on an analysis of interdisciplinary, multidisciplinary and transdisciplinary processes in modern science and culture the authors claim that it is namely transdisciplinarity would determine the face of science and culture in the medium term, and will form the basis for the convergence of science, technology, art, and consciousness studies in general.

The first part of the paper focuses on the current debate over the universality of human rights. After conceptually distinguishing between different types of universality, it employs Sen’s definition that the claim of a universal value is the one that people anywhere may have reason to see as valuable. When applied to human rights, this standard implies “thin” (relative, contingent) universality, which might be operationally worked-out as in Donnelly’s three-tiered scheme of concepts–conceptions–implementations. The second part is devoted to collective (...) rights, which have recently become a new topic of the human rights debate. This part provides the basis of political–philosophical justification and legal–theoretical conceptualization of collective rights, as rights directly vested in collective entities. The third part dwells on the problem of universality of collective rights. It differentiates between the three main collective entities in international law—peoples, minorities, and indigenous peoples—and investigates whether certain rights vested in these collectives might, according to Sen’s standard, acquire the status of the universal ones. After determining that some rights are, in principle, plausible candidates for such a status in international law, this paper concludes by taking notice of a number of the open issues that still need to be settled, primarily by the cooperative endeavor of international legal scholars and legal theorists.

This book presents a comprehensive mathematical study of the operators behind the Born-Jordan quantization scheme. The Schrödinger and Heisenberg pictures of quantum mechanics are equivalent only if the Born-Jordan scheme is used. Thus, Born-Jordan quantization provides the only physically consistent quantization scheme, as opposed to the Weyl quantization commonly used by physicists. In this book we develop Born-Jordan quantization from an operator-theoretical point of view, and analyze in depth the conceptual differences between the two schemes. We discuss various (...) physically motivated approaches, in particular the Feynman-integral point of view. One important and intriguing feature of Born-Jordan quantization is that it is not one-to-one: there are infinitely many classical observables whose quantization is zero. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Picturing Hegel: An Illustrated Guide to Hegel’s Encyclopaedia LogicJames A. Dunson IIIJulie E. Maybee. Picturing Hegel: An Illustrated Guide to Hegel’s Encyclopaedia Logic. Lanham, MD: Lexington Books, 2009. Pp. xxvii + 639. Paper, $56.95.If Hegel were alive to read an illustrated guide to his Encyclopaedia Logic, he might not immediately appreciate the project. Not only did he consider “picture-thinking” deficient in comparison to conceptual thinking, but (...) he regarded the Encyclopaedia Logic as a text suitable for German students. In her recent book, Picturing Hegel, Julie Maybee acknowledges these ironies and proceeds to guide those of us who need a little extra help in understanding Hegel’s speculative logic.What results is a significant contribution to the literature, a step-by-step commentary [End Page 536] through one of Hegel’s most underappreciated works. Using diagrams to cut through the often-difficult prose proves to be an excellent strategy. Maybee’s exquisitely detailed and admirably clear exposition makes her a suitable Virgil to guide us through the Inferno of Hegel’s logic.Maybee’s task is to show how Hegel’s logic is, actually, logical, and not, as she puts it, “A jumble of random moves from one step to the next” (xiii). She distinguishes Hegel’s speculative logic from the logic we teach nowadays by emphasizing Hegel’s concern to generate and develop the concepts he employs. That is, he is concerned not merely with the rules connecting the logical terms (i.e. syntax), but also the meanings of the terms themselves (i.e. semantics).As one might expect, these concepts are developed dialectically: two elements that are ordinarily opposed to one another are revealed to be mutually defining and interdependent. Readers already familiar with Hegel’s work will appreciate the way in which Maybee explains complicated ideas like “Actuality” and “spurious infinity.” Maybee has a talent for inventive examples, some of which she carefully carries through the entire work. Also, she has an eye for Hegel’s own examples (see, for instance, the comparison of the Absolute Idea and an old man on 580–82).One of the chief merits of her detailed account is its balanced approach. Instead of perpetuating prevalent but superficial interpretations, she explains the different senses in which something is true. For instance, she distinguishes the different meanings of idealism and shows how Hegel retains some materialist elements in his logic (302). Her knowledge of the history of philosophy helps her to put Hegel’s logic in its proper context. The asides to the Pre-Socratic philosophers and the repeated references to Kant are especially useful.Maybee’s approach to the logic, especially the way in which she frames Hegel’s project, raises interesting philosophical questions. She portrays Hegel as attempting to overcome Kant’s skepticism regarding the unity of thought and being. The question is whether reality is fundamentally accessible to reason, or whether the categories we employ to understand the world are limited to our phenomenal experience.But if Hegel’s logic is supposed to refute the Kantian “thing-in-itself,” we can ask whether this is an intelligible philosophical goal. First, Maybee points out that critics like Nietzsche would ask whether we have to be “committed to logical or conceptual necessity” (130). Perhaps Hegel exhibits a rather typical philosophical bias toward conceptual stability and even necessity. Second, any investigation into logical semantics that is biased in this way inevitably opens Pandora’s Box. Determining the meaning of logical terms is a messy business, and Hegel sometimes seems to stipulate meanings instead of genuinely deriving them. For instance, as Maybee writes, a crucial part of Hegel’s definition of existence is that something is “capable of being experienced” (204). But this simply begs the question against Kant’s “thing-in-itself,” since clearly Kant does not think it exists in this way.Third, given that Maybee points out Hegel’s anthropocentric language, we can ask whether his casual and frequent references to human experience are innocent or self-undermining. For instance, what are we to make of Hegel’s use of ethical examples to explain logical concepts like actuality, necessity, and possibility? A Kantian might... (shrink)

Situated within the framework of the conceptual metaphor theory, this article examines universal versus language-specific patterns in metaphorical motion event descriptions, comparing English and Turkish. The analysis focused on the crosslinguistic similarities and differences in the target domains and the types of metaphorical mappings that are structured by spatial motion. The data included written texts in English and Turkish. Results indicated strong crosslinguistic similarity in the target domains and the types of metaphorical mappings. Crosslinguistic variation, on the other hand, (...) became evident in the specification of the source domain structure, particularly in describing the manner component of a metaphorical motion event. English writers paid greater linguistic attention to the way one moves from point A to point B metaphorically, using a greater amount and variety of motion verbs that encoded manner. Overall, the analysis revealed the source domain structure to be the best candidate for systematic language-based variation in a metaphorical event. (shrink)

Despite widespread confusion over its meaning, the notion of a conceptual scheme is pervasive in Anglo-American philosophy, particularly amongst those who call themselves ' conceptual relativists'. In this paper, I identify three different ways to understand conceptual schemes. I argue that the two most common models, deriving from Kant and Quine, are flawed, and, in addition, useless for the relativist. Instead, I urge adoption of a 'neo-Kantian', broadly Wittgensteinian model, which, it is ' argued, is (...) immune from Davidsonian objections to the very idea of a scheme. (shrink)

This paper considers the connection between concepts, conceptual schemes and grammar in Wittgenstein’s last writings. It lists eight claims about concepts that one can garner from these writings. It then focuses on one of them, namely that there is an important difference between conceptual and factual problems and investigations. That claim draws in its wake other claims, all of them revolving around the idea of a conceptual scheme, what Wittgenstein calls a ‘grammar’. I explain why Wittgenstein’s (...) account does not fall prey to Davidson’s animadversions against the idea of a conceptual scheme as a force operating on a pre-conceptual content. In the sequel I deny that the distinction between grammatical and empirical propositions disappears in the last writings: it is neither deliberately abandoned, nor willy-nilly undermined by the admission of hinge propositions in On Certainty or by the role accorded to agreement in judgement.

The purpose of this special issue and the conference that inspired it was to address the issue of conceptual integration in a science of consciousness. We felt this to be important, for while current efforts to scientifically investigate consciousness are taking place in an interdisciplinary context, it often seems as though the very terms being used to sustain a sense of interdisciplinary cooperation are working against it. This is because it is this very array of common concepts that generates (...) a sense of unity among consciousness researchers, despite the fact the concepts mean different things in different disciplines. These Concepts of Consciousness include the following: realism, representation, intentionality, information, control, memory and self. Given this list, we believed we could best approach the issue of potential conceptual integration by addressing each concept from different perspectives and asking the following: how do uses of the concept differ, must these meanings be synthesized in order for there to be a unified science of consciousness, is a unified conceptual scheme necessary to establish an independent science of consciousness, is a unified conceptual scheme possible, if it is not possible, why not, and if it is possible, what might it look like? To this end we invited, for each concept, two scholars who made extensive use of the identified concept in their work. The papers entailed in this special issue constitute the outcome of this effort, and in what follows we offer a brief examination of possible forms of integration the papers seem to collectively suggest.

Early versions of satellite and radiosonde datasets suggested that the tropical surface had warmed more than the troposphere, while climate models consistently showed tropospheric amplification of surface warming in response to human-caused increases in greenhouse gases. We revisit such comparisons here using new observational estimates of surface and tropospheric temperature changes. We find that there is no longer a serious discrepancy between modeled and observed trends in the tropics. Our results contradict a recent claim that all simulated temperature trends in (...) the tropical troposphere are inconsistent with observations. This claim was based on the use of older radiosonde and satellite datasets and on two methodological errors: the neglect of observational trend uncertainties introduced by interannual climate variability and application of an inappropriate statistical “consistency test”.This emerging reconciliation of models and observations has two primary explanations. First, because of changes in the treatment of buoy and satellite information, new surface temperature datasets yield slightly reduced tropical warming relative to earlier versions. Second, recently developed satellite and radiosonde datasets now show larger warming of the tropical lower troposphere. In the case of a new satellite dataset from remote sensing systems, enhancedRSS warming is due to an improved procedure of adjusting for inter-satellite biases. When the RSS-derived tropospheric temperature trend is compared with four different observed estimates of surface temperature change, the surface warming is invariably amplified in the tropical troposphere, consistent with model results. Even if we use data from a second satellite dataset with smaller tropospheric warming than in remote sensing systems RSS, observed tropical lapse rates are not significantly different from those in all model simulations.Our results contradict a recent claim that all simulated temperature trends in the tropical troposphere and in tropical lapse rates are inconsistent with observations. This claim was based on the use of older radiosonde and satellite datasets and on two methodological errors: the neglect of observational trend uncertainties introduced by interannual climate variability and application of an inappropriate statistical “consistency test”.

Climate change assessments rely upon scenarios of socioeconomic developments to conceptualize alternative outcomes for global greenhouse gas emissions. These are used in conjunction with climate models to make projections of future climate. Specifically, the estimations of greenhouse gas emissions based on socioeconomic scenarios constrain climate models in their outcomes of temperatures, precipitation, etc. Traditionally, the fundamental logic of the socioeconomic scenarios—that is, the logic that makes them plausible—is developed and prioritized using methods that are very subjective. This introduces a fundamental (...) challenge for climate change assessment: The veracity of projections of future climate currently rests on subjective ground. We elaborate on these subjective aspects of scenarios in climate change research. We then consider an alternative method for developing scenarios, a systems dynamics approach called ‘Cross-Impact Balance’ (CIB) analysis. We discuss notions of ‘objective’ and ‘objectivity’ as criteria for distinguishing appropriate scenario methods for climate change research. We distinguish seven distinct meanings of ‘objective,’ and demonstrate that CIB analysis is more objective than traditional subjective approaches. However, we also consider criticisms concerning which of the seven meanings of ‘objective’ are appropriate for scenario work. Finally, we arrive at conclusions regarding which meanings of ‘objective’ and ‘objectivity’ are relevant for climate change research. Because scientific assessments uncover knowledge relevant to the responses of a real, independently existing climate system, this requires scenario methodologies employed in such studies to also uphold the seven meanings of ‘objective’ and ‘objectivity.’.

Recent conceptualization of built‐in versus bolted‐on corporate social responsibility (CSR) initiatives has offered a much‐needed distinguishing framework to sophisticate our understanding of why different CSR initiatives yield varying corporate social performance (CSP) and associated recognition from stakeholders. One of the major roadblocks in conducting research on these two types of CSR initiatives is the absence of a valid and reliable measure. We address this void by developing a measure for bolted‐on versus built‐in CSR that relies on coding publicly available (...) content. Our measure of these two types of CSR initiatives tests favorably for both convergent and discriminant validity and inter‐rater reliability. Advancement of such a measurement instrument will positively contribute to CSR research, enabling scholars to better theorize the linkage between CSR and reputation, and other aspects of firm performance.

Millions of people in the developing world lack access to curative drugs. Pogge identifies the cause of this problem as a lack of redistribution across borders. In contrast, this article shows that institutional shortcomings within developing countries are the main issue. These different explanations are the result of diverging analytic approaches to ethics: a cosmopolitan approach versus an ordonomic approach. This article compares both approaches with regard to how they conceptualize and propose to solve the problem of providing life-saving (...) pharmaceuticals to the poor in developing countries.

Four experiments tested three competing theories of metaphor comprehension: comparison, categorization, and career-of-metaphor. The findings shed light on key mechanisms involved in metaphor processing and conceptual combination. They show that some novel tropes are privileged in metaphor over simile form, and others may express different interpretations in simile and in metaphor form. These results speak against the assumption that metaphors and similes are interchangeable, thus providing support for the categorization model. A unifying account of metaphor comprehension is (...) proposed, along with a discussion of implications for conceptual combination. (shrink)

Davidson’s 1974 argument denying the possibility of incommensurable conceptual schemes is widely interpreted as entailing a denial of metaphysical pluralism. Speakers may group objects differently or have different beliefs about the world, but there is just one world. I argue there is tension arising from three aspects of Davidson’s philosophy: the 1974 argument against conceptual schemes; Davidson’s more recent emphasis on primitive triangulation as a necessary condition for thought and language; and Davidson’s semantic approach to (...) metaphysics, what he calls ‘the method of truth in metaphysics’. After elucidating the tension, I argue the tension can be resolved while preserving at least two major tenets of Davidson’s philosophy: conceptual schemes do not carve an uninterpreted reality into different worlds and truth is objective and non-epistemic. I argue Davidson is implicitly committed to a plurality of worlds. (shrink)

This article analyses the different connotations of “normality” and “being natural,” bringing together the theoretical discussion from both human medicine and veterinary medicine. We show how the interpretations of the concepts in the different areas could be mutually fruitful. It appears that the conceptions of “natural” are more elaborate in veterinary medicine, and can be of value to human medicine. In particular they can nuance and correct conceptions of nature in human medicine that may be too idealistic. Correspondingly, (...) the wide ranging conceptions of “normal” in human medicine may enrich conceptions in veterinary medicine, where the discussions seem to be sparse. We do not argue that conceptions from veterinary medicine should be used in human medicine and vice versa, but only that it could be done and that it may well be fruitful. Moreover, there are overlaps between some notions of normal and natural, and further conceptual analysis on this overlap is needed. (shrink)
