I also show how the rejection of the identity of indiscernibles derives some of its support from its affinity with a Kripkean account of trans-world identity and theories of direct reference.

[source] Locating Responsibility: The Sphere Humanitarian Charter and Its RationaleDISASTERS, Issue 2 2004James Darcy Criticised by some as a technical initiative that neglects core principles, Sphere was seen by its originators precisely as an articulation of principle. The Humanitarian Charter was the main vehicle through which this was expressed, but its relationship to the Minimum Standards has remained a matter of uncertainty. Specifically, it was unclear in the original (1999) edition of Sphere how the concept of rights informed the Minimum Standards. The revised (2004) edition goes some way to clarifying this in the way the standards are framed, yet the link between the standards and the charter remains unclear. The concern with the quality and accountability of humanitarian assistance, which motivated the attempt to establish system-wide standards through the Sphere Project, was accompanied by a desire to establish such actions in a wider framework of legal and political responsibility. In part, this reflects the conditional nature of the undertaking that agencies make when they adopt Sphere. This aspect of the charter has been neglected, but it is fundamental to an understanding of the standards and their application. This paper considers the rationale of the Sphere Humanitarian Charter and the conceptual model that underpins it. It discusses the relationship between the charter and the Minimum Standards, and the sense in which the latter are properly called ,rights-based' (explored further in a related paper herein by Young and Taylor). The author was closely involved in the conception and drafting of the charter, and this paper attempts to convey some of the thinking that lay behind it. [source] Two New Iron(II) Spin-Crossover Complexes with N4O2 Coordination Sphere and Spin Transition around Room TemperatureEUROPEAN JOURNAL OF INORGANIC CHEMISTRY, Issue 36 2009Birgit Weber Abstract The reaction of iron(II) acetate with the tetradentate Schiff base like ligand H2L1 {[3,3,]-[4,5-dihydroxy-1,2-phenylenebis(iminomethylidyne)bis(2,4-pentanedion)]} leads to the formation of the complex [FeL1(MeOH)]. Reaction of this complex with pyridine (py) or N,N,-dimethylaminopyridine (dmap) leads to the two N4O2 -coordinated complexes [FeL1(py)2]·py (1) and [FeL1(dmap)2]·MeOH·0.5dmap (2). Both complexes are spin-crossover compounds that were characterised by using magnetic measurements, X-ray crystallography and temperature-dependent 1H NMR spectroscopy. Special attention was given to the role of the two hydroxy groups on the phenyl ring in the formation of a hydrogen-bonding network and the influence of this network on the spin-transition properties. Although only a gradual spin crossover was observed for both complexes, the transition temperature was shifted to higher temperatures relative to that of the complexes with no additional hydroxy groups at the Schiff base like ligand. The hydrogen-bonding network was responsible for this effect.(© Wiley-VCH Verlag GmbH & Co.

These crown ethers form 2:1, 3:2 and 1:1 complexes with AgY (Y = BF4, PF6). The crystal structures of [Ag(mn12S4)2]BF4 (3a), [Ag(mn13S4)2]BF4 (4a) and [Ag2(mn13S4)3](PF6)2 (6b) have been determined. Compound 3a contains the centrosymmetric sandwich complex cation [Ag(mn12S4)2]+ where each mn12S4 ligand is coordinated to the Ag centre in an endo manner through all four S atoms. The 2:1 complex [Ag(mn12S4)2]+ is the first sandwich complex with a tetrathiacrown ether and the first complex with an octa(thioether) coordination sphere. The crystal structure of compound 4a also reveals a 2:1 complex. This complex, [Ag(mn13S4)2]+, exhibits a half-sandwich structure. One mn13S4 ligand coordinates to Ag+ by all four S donor atoms and the other 13S4 crown by only one S atom. Compound 6b contains a dinuclear Ag complex. The Ag complexes 3a,b,8a,b were also studied by electrospray ionisation mass spectrometry. Collision-induced dissociation (CID) was used to compare the relative stability of 2:1 complexes [AgL2]+ and 1:1 complexes [AgL]+ (L = mn12S4, mn13S4). The 13C NMR chemical shifts of 2:1 and 1:1 Ag complexes and their corresponding free ligands were also estimated and compared. The free energy of the barrier of ring inversion (,G,) for [Ag(mn12S4)2]+ was determined to be 64 kJ,mol,1. (© Wiley-VCH Verlag GmbH & Co.

New political rationalities that constituted modern governmental power and the liberal technologies of government effected a new conception of economy and society. Governmentality's governance of colonial conduct in an improving direction socialized native public opinion to question the legitimacy of the colonial covenant. As native opinion against colonial rule sharpened, colonial liberalism had often to make a volte-face of its liberal principle and was forced to suppress public opinion. Gandhi alone sought to overturn colonial governmentality and in doing so, provided a conception of public opinion that could transcend the limits of liberal reason. [source] New Directions in British Art History of the Eighteenth CenturyLITERATURE COMPASS (ELECTRONIC), Issue 5 2008Douglas Fordham This essay examines new developments in the history of eighteenth-century British art since the publication of David Solkin's Painting for Money: The Visual Arts and the Public Sphere in Eighteenth-Century England in 1993. While Solkin's account of an urban professional class recasting a civic humanist ideology in its own polite and commercial image continues to hold tremendous sway in the field, this state of the field article identifies three major trends that have tempered and challenged that account. Recent scholarship dealing with gender, space, and empire has subtly reoriented the field towards a more inclusive notion of artistic agency and reception, a more synchronic and spatial approach, and an increasingly global perspective.

[source] Anthropology in the Public Sphere, 2008: Emerging Trends and Significant ImpactsAMERICAN ANTHROPOLOGIST, Issue 2 2009Melissa Checker ABSTRACT The themes, trends, and significant events of 2008 demonstrate that anthropology has established a new foothold in the public sphere,one that makes the most of novel forms of communication to reach far beyond the ivory tower to disseminate knowledge widely and freely. This review focuses on six topical areas of robust anthropological research in 2008 that also addressed some of the year's most pressing problems and issues, including the following: (1) war and peace; (2) climate change; (3) natural, industrial, and development-induced disaster recovery; (4) human rights; (5) health disparities; and (6) racial understanding, politics, and equity in the United States. It concludes by addressing some emerging issues in 2009 that especially require anthropological attention and insight, if we are to move beyond "business as usual."[Keywords: practicing anthropology, public anthropology, 2009 trends, anthropological impacts] [source] Museums, Information and the Public SphereMUSEUM INTERNATIONAL, Issue 4 2002Barbara Lang Rottenberg [source] Sphere of Nursing Advocacy ModelNURSING FORUM, Issue 3 2005FNP-C, Robert G. Hanks RNC The Sphere of Nursing Advocacy (SNA) model explains and depicts nursing advocacy on behalf of a client. The SNA model views the client as continually protected from the external environment by a semipermeable sphere of nursing advocacy that allows clients to self advocate if the client is emotionally and physically able or to be advocated for by the nurse if the patient is unable to advocate for him- or herself. The SNA model can be used to guide research or it can provide the basis for instruction on the subject of nursing advocacy. [source] Parliament in the Public Sphere: A View of Serial Coverage at the Turn of the Seventeenth CenturyPARLIAMENTARY HISTORY, Issue 1 2007MICHAEL HARRIS First page of article [source] Thinking for Thousands: Emerson's Theory of Political Representation in the Public SphereAMERICAN JOURNAL OF POLITICAL SCIENCE, Issue 1 2005Hans Von Rautenfeld This article develops Emerson's theory of representative democracy as it applies to a deliberative public sphere. By highlighting the democratic content of Emerson's thought, this article challenges tradition readings of Emerson that claim his thought to be elitist or antipolitical. According to Emerson, the public sphere is structured by representative individuals who are analogous to those representatives found in electoral institutions. These representatives make public the beliefs and values present in their "constituencies." They deliberate in the name of their constituencies, saying what their constituencies could and would say, were they to also directly engage in such deliberations. Representative individuals are tied to their constituencies through bonds of "sympathy and likeness." The moral consequences of a representative public sphere include the development of a sense of deliberative justice on the part of the citizenry and the reduction of the possibility of domination and oppression by ideologically oriented elites. [source] SLICE-S: A Semi-Lagrangian Inherently Conserving and Efficient scheme for transport problems on the SphereTHE QUARTERLY JOURNAL OF THE ROYAL METEOROLOGICAL SOCIETY, Issue 602 2004Mohamed Zerroukat Abstract The Semi-Lagrangian Inherently Conserving and Efficient (SLICE) scheme developed for Cartesian geometry is generalized to spherical geometry. The spherical version, SLICE-S, is similarly based on a Control Volume approach and multiple sweeps of a one-dimensional O(,s4) (where s is the spherical distance) conservative remapping algorithm along Eulerian latitudes, then along Lagrangian longitudes. The resulting conservative scheme requires no restriction on either the polar meridional or zonal Courant numbers. SLICE-S is applied to the standard problems of solid-body rotation and deformational flow, and results are compared with those of a standard non-conservative and other published conservative semi-Lagrangian schemes. In addition to mass conservation, and consistent with the performance of SLICE, the present scheme is competitive in terms of accuracy and efficiency. © Crown copyright, 2004.

[source] Mesoporous Silicas by Self-Assembly of Lipid Molecules: Ribbon, Hollow Sphere, and Chiral MaterialsCHEMISTRY - A EUROPEAN JOURNAL, Issue 21 2008Haiying Jin Abstract Using lipids (N -acyl amino acids) and 3-aminopropyltriethoxysilane as structure- and co-structure-directing agents, mesoporous silicas with four different morphologies, that is, helical ribbon (HR), hollow sphere, circular disk, and helical hexagonal rod, were synthesized just by changing the synthesis temperature from 0,°C to 10, 15, or 20,°C. The structures were studied by electron microscopy. It was found that 1),the structures have double-layer disordered mesopores in the HR, radially oriented mesopores in the hollow sphere, and highly ordered straight and chiral 2D-hexagonal mesopores in the disklike structure and helical rod, respectively; 2),these four types of mesoporous silica were transformed from the flat bilayered lipid ribbon with a chain-interdigitated layer phase through a solid,solid transformation for HR formation and a dissolving procedure transformation for the synthesis of the hollow sphere, circular disk, and twisted morphologies; 3),the mesoporous silica helical ribbon was exclusively right-handed and the 2D-hexagonal chiral mesoporous silica was excessively left-handed when the L -form N -acyl amino acid was used as the lipid template; 4),the HR was formed only by the chiral lipid molecules, whereas the 2D-hexagonal chiral mesoporous silicas were formed by chiral, achiral, and racemic lipids. Our findings give important information for the understanding of the formation of chiral materials at the molecular level and will facilitate a more efficient and systematic approach to the generation of rationalized chiral libraries. [source] Voltammetric Sizing of a SphereCHEMPHYSCHEM, Issue 10 2006Nicole Fietkau Abstract The size of a glass sphere positioned in the center of a microdisk electrode is determined by using a simple electrochemical procedure and is confirmed, additionally, by a microscopical measurement of the sphere at the time of the electrochemical measurement. The cyclic voltammetric response of the naked electrode and of the electrode with the sphere positioned in its center is recorded over a wide range of scan rates (0.002,1.5 V,s,1). The size of the sphere is then determined by comparison of the experimental voltammogram with simulations for each individual scan rate. [source] Rethinking the Black Public Sphere: An Alternative Vocabulary for Multiple Public SpheresCOMMUNICATION THEORY, Issue 4 2002Catherine R. Squires Many theorists propose that there are multiple, coexisting "subaltern" counterpublic spheres. However, most discussions of these subaltern counterpublics rely on group identity markers to differentiate between these spheres and do not provide alternative means for distinguishing between subaltern public spheres. This essay presents an alternative vocabulary for multiple public spheres through an exploration of the history of the African American public sphere. Three types of marginal publics, enclave, counterpublic, and satellite, are defined as examples of how we might incorporate considerations of the kinds of resources different publics have available to them. This vocabulary facilitates more flexible descriptions of publics that are normally defined by identity and allows for more comprehensive comparisons across public spheres.

Additionally, [Y(hfa)3·monoglyme] and [Y(hfa)3·diglyme] were characterized by single-crystal X-ray diffraction studies. The mass-transport properties of these adducts were investigated by thermogravimetric analysis, differential scanning calorimetry, evaporation-rate measurements and chemical vapour-deposition experiments. There is evidence of high volatility and very good thermal stabilities with a residue lower than 2,4 %. Vaporization-rate experiments proved that all adducts are well-suited for metal-organic chemical vapour-deposition experiments. The [Y(hfa)3·monoglyme] complex was successfully applied in the low-pressure MOCVD process of YBaCuO HTc superconductor using a multimetal molten single source. (© Wiley-VCH Verlag GmbH & Co.

The MCM-41-SCK system was prepared by dipping the glass,ceramic scaffold into the MCM-41 synthesis solution and was characterized by means of XRD, micro-XRD, N2 sorption and scanning electron microscopy. The MCM-41 spheres inside the scaffold are highly uniform in diameter, as those synthesized in powder form. The adsorption capacity of the composite toward ibuprofen is three times higher than that of the MCM-41-free scaffold, because of the presence of the ordered mesoporous silica. Also the release behavior in SBF at 37,°C is strongly affected by the presence of MCM-41 inside the scaffold macropores. [source] Titanium Containing ,-MnO2 (TM) Hollow Spheres: One-Step Synthesis and Catalytic Activities in Li/Air Batteries and Oxidative Chemical ReactionsADVANCED FUNCTIONAL MATERIALS, Issue 19 2010Lei Jin Abstract Titanium containing ,-MnO2 octahedral molecular sieves having hollow sphere structures are successfully prepared for the first time using a one-step synthesis method. Titanium cations are used as structure-directing agents in the synthesis process. The assembly of the hollow spheres is carried out at the beginning of the process. Various techniques including XRD, N2 adsorption, SEM, EDX, RAMAN, TEM, XPS, and TGA are employed for the materials characterization. Ti is incorporated into the MnO2 framework in isolated sites, and TiO2 phases (anatase and rutile) are not observed. When introduced in medium-sized lithium-air batteries, the materials give very high specific capacity (up to 2.3 A h g,1). These materials are also catalytically tested in the oxidation of toluene with molecular oxygen at atmospheric pressure, showing significant oxidative catalytic activities in this difficult chemical reaction. [source] Synthesis and Lithium Storage Properties of Co3O4 Nanosheet-Assembled Multishelled Hollow SpheresADVANCED FUNCTIONAL MATERIALS, Issue 10 2010Xi Wang Abstract Single-, double-, and triple-shelled hollow spheres assembled by Co3O4 nanosheets are successfully synthesized through a novel method. The possible formation mechanism of these novel structures was investigated using powder X-ray diffraction, scanning and transmission electron microscopies, Fourier transform IR, X-ray photoelectron spectroscopy, and thermogravimetric analysis. Both poly(vinylpyrrolidone) (PVP) soft templates and the formation of cobalt glycolate play key roles in the formation of these novel multishelled hollow structures. When tested as the anode material in lithium-ion batteries (LIBs), these multishelled microspheres exhibit excellent cycling performance, good rate capacity, and enhanced lithium storage capacity. This superior cyclic stability and capacity result from the synergetic effect of small diffusion lengths in the nanosheet building blocks and sufficient void space to buffer the volume expansion. This facile strategy may be extended to synthesize other transition metal oxide materials with hollow multishelled micro-/nanostrucutures, which may find application in sensors and catalysts due to their unique structural features. [source] Enhanced Optical Properties and Opaline Self-Assembly of PPV Encapsulated in Mesoporous Silica SpheresADVANCED FUNCTIONAL MATERIALS, Issue 23 2009Timothy L. Kelly Abstract A new poly(p -phenylenevinylene) (PPV) composite material has been developed by the incorporation of insoluble PPV polymer chains in the pores of monodisperse mesoporous silica spheres through an ion-exchange and in situ polymerization method. The polymer distribution within the resultant colloidal particles is characterized by electron microscopy, energy dispersive X-ray microanalysis, powder X-ray diffraction, and nitrogen adsorption. It was found that the polymer was selectively incorporated into the mesopores of the silica host and was well distributed throughout the body of the particles. This confinement of the polymer influences the optical properties of the composite; these were examined by UV,vis and fluorescence spectroscopy and time-correlated single-photon counting. The results show a material that exhibits an extremely high fluorescence quantum yield (approaching 85%), and an improved resistance to oxidative photobleaching compared to PPV. These enhanced optical properties are further complemented by the overall processability of the colloidal material. In marked contrast to the insolubility of PPV, the material can be processed as a stable colloidal dispersion, and the individual composite spheres can be self-assembled into opaline films using the vertical deposition method. The bandgap of the opal can be engineered to overlap with the emission band of the polymer, which has significant ramifications for lasing. [source] | ||||||||||||||||||||||||||||||||||||||||
