Hybrid Theory

Both descriptivism and the causal theory of reference fail to account for the meaning of theoretical terms in a way consistent with scientific realism. Faced with this problem, hybrid theories of reference have been developed. They combine features of both descriptivism and the causal theory and seek to capture the advantages of each. In this work, we critically analyze two strategies to articulate hybrid theories of reference in the face of the problem of the meaning of theoretical terms. They are exemplified by the proposals of Psillos and Kitcher. We argue that neither of these strategies is successful in articulating the descriptive and causal elements in a genuine hybrid theory of reference that satisfies the standards of scientific realism.

ABSTRACTIan Hacking puts forward a distinction between two kinds of scientific realism. According to scientific realism about theories, scientific theories are accepted as approximately true; according to scientific realism about unobservable entities, the theoretical terms occurring in scientific theories refer to existing, real entities. This article seeks to show that Claude Bernard's philosophy of science is a realist one about scientific theories, but anti-realist about unobservable entities. The term “fictionalism” is used here to stand for this sort of anti-realism about unobservable entities.

AbstractHuman reasoning is richer than Lake et al. acknowledge, and the emphasis on theories of how images and scenes are synthesized is misleading. For example, the world knowledge used in vision presumably involves a combination of geometric, physical, and other knowledge, rather than just a causal theory of how the image was produced. In physical reasoning, a model can be a set of constraints rather than a physics engine. In intuitive psychology, many inferences proceed without detailed causal generative models. How humans reliably perform such inferences, often in the face of radically incomplete information, remains a mystery.

This project has investigated African graphic systems, both writing systems and systems of symbolic graphics. These systems are commonly used in Graphic Design, but those of African origin have been largely ignored in both the applied discipline, and in its History and Theory. The project has attempted to explain this in historical and theoretical terms: its motivation is described in terms of countering the exclusion of African visual culture in the face of historical and ideological factors such as colonialism and globalisation. The project's research aims were to collect as much information as feasible on these systems; and to classify them according to such criteria as their language or cultural group, their location, and the functional nature of the systems. From this body of information a smaller number of representative systems were selected for further description and discussion, in order to highlight the variety of systems existing in Africa, their historical development, and techniques and materials used. These selected systems were then used as inspiration and raw material for a body of applied Graphic Design work, which is intended to provide a visual introduction to the material, and to promote and advocate the revaluation of this cultural material. Information has mainly been gathered by means of library and internet search, in order to establish approximately the extent of the literature in the public sphere. Because of the obscurity of most of this information, it has been gathered from such other disciplines as Linguistics, Anthropology, or History. The project has established the existence of a large number of graphic symbols and systems, and gathered a body of literature and references about them. Many are poorly documented, if at all, and even those for which extensive literature

Generating innovation with environmental impact is crucial for firms to achieve sustainable eco-innovative performance. In the reference literature on open innovation, gaps still persist at the level of scarce and limited knowledge on the use of knowledge sources and flows, for the purpose of strengthening the eco-innovative performance of the bioeconomy sector. To address these caveats, this study analyses the effects of open innovation on eco-innovation, based on inbound and outbound support practices. Specifically, it aims to analyse the effects of these practices on the eco-innovative performance of bioeconomy and non-bioeconomy firms, using secondary data gathered from the Community Innovation Survey—CIS 2010 for a sample of moderately innovative countries, namely Slovakia, Spain, Hungary, Italy, Portugal and the Czech Republic. The conceptual model proposed is tested using multivariate tobit regression models, in order to ensure the accuracy and reliability required to validate empirical tests. Overall, the empirical evidence allows the conclusion that inbound and outbound practices and public policies have a positive and significant influence on the eco-innovative performance of the firms studied. The contribution provided is two-fold: (i) in theoretical terms, an operational model of open innovation inbound and outbound practices is extended, crossing financial flows and innovation directions; and (ii) in empirical terms, new light is shed on the still limited knowledge about the positive and significant effects of open innovation outbound practices on the eco-innovative performance of companies belonging to a global strategic sector—that is, the bioeconomy sector, which has renewed strategic importance in the face of global climate change.

Theories Of Science

A popular explanation of the success of theories of science is that of scientific realism. It maintains, besides that the theories of a mature science are typically approximately true, that observational terms and theoretical terms refer to or denote entities. Therefore it is part of the realistic claim that "reference" explains "success." But if the realist is not able to clarify "reference" and a fortiori the reference on theoretical objects, the realist comes to a vicious circle, for there is no further criterion as the success of the theory to show that the term is referential. So it is necessary to clarify the notion "reference." Needless to say, "reference" is a relational term; but it easily becomes a problem that we are not only habituated to imagine the elation but we are convinced that a relation is just a relation between entities in a strict (viz., Quinian) sense. There are different kinds of references. For example, one is usually called "intentionality." If we, considering the traditional separation between reference and meaning, analyze meaning, we will find at least one referential component (intentional object). Such a referential process is not a meaningless aspect of linguistic reference, but now and then is the subject of the kind of relation called "denotation." The notion of meaning and the concept of reference are nonsubstantial constructions of interpretation. Nevertheless, I argue for a reference-theoretical approach.

Zero Sum

AbstractZero-sum thinking and aversion to trade pervade our society, yet fly in the face of everyday experience and the consensus of economists. Boyer & Petersen's (B&P's) evolutionary model invokes coalitional psychology to explain these puzzling intuitions. I raise several empirical challenges to this explanation, proposing two alternative mechanisms – intuitive mercantilism (assigning value to money rather than goods) and errors in perspective-taking.

Impact Erosion

AbstractThe clear evidence of water erosion on the surface of Mars suggests an early climate much more clement than the present one. Using a model for the origin of inner planet atmospheres by icy planetesimal impact, it is possible to reconstruct the original volatile inventory on Mars, starting from the thin atmosphere we observe today. Evidence for cometary impact can be found in the present abundances and isotope ratios of gases in the atmosphere and in SNC meteorites. If we invoke impact erosion to account for the present excess of129Xe, we predict an early inventory equivalent to at least 7.5 bars of CO2. This reservoir of volatiles is adequate to produce a substantial greenhouse effect, provided there is some small addition of SO2(volcanoes) or reduced gases (cometary impact). Thus it seems likely that conditions on early Mars were suitable for the origin of life – biogenic elements and liquid water were present at favorable conditions of pressure and temperature. Whether life began on Mars remains an open question, receiving hints of a positive answer from recent work on one of the Martian meteorites. The implications for habitable zones around other stars include the need to have rocky planets with sufficient mass to preserve atmospheres in the face of intensive early bombardment.

In zirconium-hydrogen alloys, rapid cooling from an elevated temperature causes precipitation of the face-centred tetragonal (fct) phase, γZrH, in the form of needles, parallel to the close-packed <1120>zr directions (1). With low hydrogen concentrations, the hydride solvus is sufficiently low that zirconium atom diffusion cannot occur. For example, with 6 μg/g hydrogen, the solvus temperature is approximately 370 K (2), at which only the hydrogen diffuses readily. Shears are therefore necessary to produce the crystallographic transformation from hexagonal close-packed (hep) zirconium to fct hydride.The simplest mechanism for the transformation is the passage of Shockley partial dislocations having Burgers vectors (b) of the type 1/3<0110> on every second (0001)Zr plane. If the partial dislocations are in the form of loops with the same b, the crosssection of a hydride precipitate will be as shown in fig.1. A consequence of this type of transformation is that a cumulative shear, S, is produced that leads to a strain field in the surrounding zirconium matrix, as illustrated in fig.2a.

Interphase sliding is an important phenomenon of high temperature plasticity. In order to study the microstructural changes associated with it, as well as its influence on the strain rate dependence on stress and temperature, plane boundaries were obtained by welding together two polycrystals of Cu-Zn alloys having the face centered cubic and body centered cubic structures respectively following the procedure described in (1). These specimens were then deformed in shear along the interface on a creep machine (2) at the same temperature as that of the diffusion treatment so as to avoid any precipitation. The present paper reports observations by conventional and high voltage electron microscopy of the microstructure of both phases, in the vicinity of the phase boundary, after different creep tests corresponding to various deformation conditions.Foils were cut by spark machining out of the bulk samples, 0.2 mm thick. They were then electropolished down to 0.1 mm, after which a hole with thin edges was made in an area including the boundary
