Folk Theories of the Third Kind

RATIO, Issue 3 2004
David Braddon-Mitchell
The idea of a folk theory has played many important roles in much recent philosophy. To do the work they are designed for, they need to be both internal features of agents who possess them, and yet scrutable without the full resources of empirical cognitive science. The worry for the theorist of folk theories, is that only one of these desiderata is met in each plausible conception of a folk theory. This paper outlines a third conception that meets them both.1 [source]


Dynamic response of soft poroelastic bed to linear water waves,a boundary layer correction approach

INTERNATIONAL JOURNAL FOR NUMERICAL AND ANALYTICAL METHODS IN GEOMECHANICS, Issue 7 2001
Ping-Cheng Hsieh
Abstract According to Chen et al. (Journal of Engineering Mechanics, ASCE 1997; 123(10):1041,1049.) a boundary layer exists within the porous bed and near the homogeneous-water/porous-bed interface when oscillatory water waves propagate over a soft poroelastic bed. This boundary layer makes the evaluation of the second kind of longitudinal wave inside the soft poroelastic bed very inaccurate. In this study, the boundary layer correction approach for the poroelastic bed is applied to the boundary value problem of linear oscillatory water waves propagating over a soft poroelastic bed. After the analyses of length scale and order of magnitude of physical variables are done, a perturbation expansion for the boundary layer correction approach based on two small parameters is proposed and solved. The solutions are carried out for the first and third kind of waves throughout the entire domain. The second kind of wave which disappears outside the boundary layer is solved systematically inside the boundary layer. The results are compared with the linear wave solutions of Huang and Song (Journal of Engineering Mechanics, ASCE 1993; 119:1003,1020.) to confirm the validity. Moreover, a simplified boundary layer correction formulation which is expected to be very useful in numerical computation is also proposed. Copyright © 2001 John Wiley & Sons, Ltd. [source]


Structural, electronic, and optical properties of 9-heterofluorenes: A quantum chemical study

JOURNAL OF COMPUTATIONAL CHEMISTRY, Issue 13 2007
Run-Feng Chen
Abstract Density-functional theory studies were applied to investigate the structural, electronic, and optical properties of 9-heterofluorenes achieved by substituting the carbon at 9 position of fluorene with silicon, germanium, nitrogen, phosphor, oxygen, sulfur, selenium, or boron. These heterofluorenes and their oligomers up to pentamers are highly aromatic and electrooptically active. The alkyl and aryl substituents of the heteroatom have limited influence, but the oxidation of the atom has significant influence on their molecular structures and properties. The highest occupied molecular orbital (HOMO)-lowest occupied molecular orbital (LUMO) interaction theory was successfully applied to analyze the energy levels and the frontier wave functions of these heterofluorenes. Most heterofluorenes belong to type B of interaction with low-lying LUMO and have the second kind of wave function. Carbazole and selenafluorene have type C of interaction with high-lying HOMO and the third kind of wave function. Types C and D of heterofluorenes, such as carbazole, oxygafluorene, sulfurafluorene, and selenafluorene also have high triplet state energies. The extrapolated HOMO and LUMO for polyheterofluorenes indicate that polyselenonafluorene has the lowest LUMO; polycarbazole has the highest HOMO; polyselenafluorene has the highest bandgap (Eg); and polyborafluorene has the lowest Eg. Heterofluorenes and their oligomers and polymers are of great experimental interests, especially those having extraordinary properties revealed in this study. © 2007 Wiley Periodicals, Inc.

How to handle the threat of catastrophe

JOURNAL OF CORPORATE ACCOUNTING & FINANCE, Issue 6 2003
Carol Sánchez
One major task CEOs face is to minimize risk and vulnerability to catastrophic events. Since 9/11, we know that simply having insurance,and conventional emergency planning,is not enough. And in addition to global terrorism, other catastrophes threaten,including cyber crime and new diseases like SARS. Traditional risk management strategies dealt with two types of danger: known and unknown risk. But now we also have a third kind: unknowable risk! So how should we handle catastrophic threats today? © 2003 Wiley Periodicals, Inc. [source]


Primal seduction, matricial space and asymmetry in the psychoanalytic encounter

THE INTERNATIONAL JOURNAL OF PSYCHOANALYSIS, Issue 4 2004
Viviane Chetrit-Vatine
Wishing to highlight the asymmetric dimension that characterizes ethics as ,responsibility toward the other' in Levinas's philosophy, the author presents as an introduction three related concepts of Levinas's thinking: the caress, the face, the saying. Following some poetic narrative reflections offered as ,interlude' moments, the author seeks to bring together her concept of ,matricial space' inspired by Levinas's conception of ethics and the Laplanchian concept of ,primal seduction', both based on asymmetry. She suggests adding to Laplanche's proposition of two kinds of transference (filled-in transference and hollowed-out transference) a third kind: the matricial-space transference. She argues that together with the hollowed-out transference, which is related to the primal seduction, the matricial-space transference, which relates to the matricial position in the parent/analyst, is provoked by the analyst. If the hollowed-out transference assures the moving-on of the analysis, the matricial-space transference, in combination with the hollowed-out transference, is prerequisite for transformation to occur and may be deciphered specifically in ,impasse' situations, at what she coined ,subjectal moments'. As a conclusion, while insisting on the need for asymmetry in the analytic encounter, she suggests the existence in the human neonate of a need for ethics, and she questions the origin of the human capacity to be responsible toward the other. She illustrates her argument using clinical material from her own work alongside that of other authors. [source]


Analysis of Platinum Adducts with DNA Nucleotides and Nucleosides by Capillary Electrophoresis Coupled to ESI-MS: Indications of Guanosine 5,-Monophosphate O6,N7 Chelation

CHEMBIOCHEM, Issue 11 2004
Ulrich Warnke Dr.
Abstract DNA is the ultimate target of platinum-based anticancer therapy. Since the N7 of guanine is known to be the major binding site of cisplatin and its analogues, adduct formation with model nucleotides, especially 2,-deoxyguanosine 5,-monophosphate (dGMP), has been studied in detail. During the last few years a coupled capillary eletrophoresis/electrospray-ionization mass spectrometry (CE/ESI-MS) method has been advantageously used in order to separate and identify platinum adducts with nucleotides in submillimolar concentrations in aqueous solutions. Beside the bisadduct, [Pt(NH3)2(dNMP)2]2,(NMP=2,-deoxynucleoside 5,-monophosphate), and the well-known monochloro and monohydroxo adducts, [Pt(NH3)2Cl(dNMP)],and [Pt(NH3)2(dNMP)OH],, respectively, a third kind of monoadduct species with a composition of [Pt(NH3)2(dNMP)],can be separated by CE and detected through the m/z values measured with ESI-MS. Different experimental setups indicate the existence of an O6,N7 chelate, whereas the formation of N7,,PO4macrochelates or dinuclear species is unlikely. Additionally, offline MS experiments with 2,-deoxyguanosine (dG) and stabilization of the controversially discussed O6,N7 chelate by oxidation with hydrogen peroxide support the assumption of the existence of O6,N7 chelation.
