Being lauded is not the same as being liked; celebrated products that win awards frequently fail to stand out in terms of commercial success. This work documents how creative control, the extent to which the same entity takes responsibility for all stages of the creative process, impacts which products are singled out for recognition but does not play a comparable role in determining what consumers like and thus purchase. Using real-world data, study 1 demonstrates how songs by performers who write their own material are more likely to garner acclaim but do not excel in terms of sales. Study 2 replicates the pattern of results in the lab. Study 3 reproduces the effect in a new domain (beer) using different measures of recognition. Study 4 shows creative authenticity, the extent to which a product is considered a faithful execution of its creator's vision, mediates the effect of creative control on recognition. Further, study 4 highlights the contingent role played by the perceived trustworthiness of the creator on this relationship. Finally, study 5 presents a boundary condition such that when consumers do not feel confident in their appraisals of an experience, creative control's impact on recognition and liking runs in parallel. © The Author 2015.

The authors have studied microstructure evolution during thermally induced phase separation in a class of binary supported lipid bilayers using a quantitative application of imaging ellipsometry. The bilayers consist of binary mixtures consisting of a higher melting glycosphingolipid, galactosylceramide (GalCer), which resides primarily in the outer leaflet, and a lower melting, unsaturated phospholipid, 1,2-dilauroyl-sn-glycero-3-phosphocholine (DLPC). Three different bilayer compositions of GalCer/DLPC mixtures at 35:65, 20:80, and 10:90 molar ratios were cooled at controlled rates from their high-temperature homogeneous phase to temperatures corresponding to their phase coexistence regime and imaged in real time using imaging ellipsometry. During the thermotropic course of GalCer gelation, we find that two distinct types of morphological features modulate. First, the formation and growth of chain and fractal-like defects ascribed to the net change in molecular areas during the phase transition. The formation of these defects is consistent with the expected contraction in the molecular area during the liquid crystalline to gel-phase transition. Second, the nucleation and growth of irregularly shaped gel-phase domains, which exhibit either line-tension dominated compact shape or dendritic domains with extended interfaces. Quantifying domain morphology within the fractal framework reveals a close correspondence, and the quantization of the transition width confirms previous estimates of reduced phase transition cooperativity in supported bilayers. A comparison of domain properties indicates that thermal history, bilayer composition, and cooling rate all influence microstructure details including shapes, sizes, and distributions of domains and defects: At lower cooling rates and lower GalCer fractions compact domains form and at higher GalCer fractions (or at higher cooling rates) dendritic domains are evident. This transition of domain morphology from compact shapes to dendritic shapes at higher cooling rates and higher relative fractions of GalCer suggests kinetic control of shape equilibration in these phospho- and glycolipid mixtures. © 2010 American Vacuum Society.

The link between federal housing policy and public health has been understood since the nineteenth century, when housing activists first sought to abolish slums and create healthful environments. This article describes how the Obama administration-building on these efforts and those that followed, including the Great Society programs of President Lyndon Johnson-has adopted a cross-sector approach that takes health considerations into account when formulating housing and community development policy. The federal Department of Housing and Urban Development fully embraces this "health in all policies" approach. Nonetheless, the administration's strategy faces challenges, including fiscal and political ones. Some of these challenges may be overcome by conducting quality research on how housing and community development policies affect health outcomes, and by developing a federal budget strategy that takes into account how investments in one sector contribute to cost savings in another. ©2012 Project HOPE- The People-to-People Health Foundation, Inc.

Iron nanoparticle reinforced polyacrylonitrile (PAN) nanocomposites are fabricated by a facile and environmentally benign solvent extraction method. Fourier transform infrared (FT-IR), thermal gravimetric analysis (TGA), and differential scanning calorimetry (DSC) results indicate a strong interaction between the iron nanoparticles and the polymer matrix for the as-prepared polymer nanocomposites. The heat treatment induces the carbonization of the polymer matrix. High-resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD) analysis show a protecting carbon shell surrounding the iron nanoparticles within the carbon matrix against the particle oxidation. The magnetic properties, electrical conductivity, and magnetic field dependent resistivity of heat-treated nanocomposites with different particle loadings are carried out in a physical properties measurement system by Quantum Design and by a standard four probe method. The saturation magnetization increases and the coercivity decreases with an increase of the nanoparticle loading. The heat-treated nanocomposites possess a room temperature magnetoresistance (MR) of 5.1% at a field of 90 kOe. The nanoparticle loading has a significant effect on the resistivity of nanocomposites. The heattreated nanocomposites show a particle loading dependent transport mechanism. A transition from semiconductive to metallic conduction was observed with an increase of the nanoparticle loading. © 2010 American Chemical Society.

Computational studies show that the base-mediated intramolecular Diels-Alder of tryptamine-derived Zincke aldehydes, used as a key step in the synthesis of the Strychnos alkaloids norfluorocurarine and strychnine, proceeds via a stepwise pathway. The experimentally determined importance of a potassium counterion in the base is explained by its ability to preorganize the Zincke aldehyde diene in an s-cis conformation suitable to bicyclization. Computation also supports the thermodynamic importance of the generation of a stable enolate in the final reaction step. The thermal cycloreversion reaction of the Diels-Alder products is also found to proceed in a stepwise manner. © 2012 The Royal Society of Chemistry.

There is general consensus that the press is undergoing a fundamental shift in how it functions as a profession, a business, and a social institution due, in part, to the proliferation and practices of online networked media. But there is still little understanding of exactly how this shift can and should relate to journalism's role as a public-facing profession that produces and vets information using logics other than those offered by markets. We explore one aspect of this issue here by developing an argument for how and why the state might support online, networked journalism, arguing that the press is a unique guardian of the public interest and presenting ways in which it might help to create a robust online public sphere.

In this paper we describe a methodology that uses interval type-2 fuzzy logic to translate words that refer to emotions from Spanish to English. We build on previous research that aimed to map between emotional labels used in different natural language corpora. In this paper we extend our previous work by showing how a similar method can be used to translate between languages. First, we show how this methodology relates to other fuzzy logic emotion research, then we describe it, and finally show it in use and discuss its results. © 2010 IEEE.

Software evaluation has evolved and taken several forms, providing rapid change handling and high assurance. The single-step-to-full-capability process exemplified by the traditional waterfall or sequential V-model is appropriate if the product's requirements are prespecifiable and have a low probability of significant change, and if there's no value or chance to deliver a partial product capability. The evolutionary sequential process develops an initial operational capability and upgrades it on the basis of operational experience. Development team stabilized for on-time, high-assurance delivery of the current increment and employing a concurrent verification and validation team to perform continuous defect detection to enable even higher-assurance levels.

The Maestro Flight Experiment (MFE) demonstrates the operation of a modern, many-core radiation hardened processor (the Maestro ITC) in space. The MFE executes diagnostics, performs image processing activities, addresses strategies for dealing with thermal and power constraints in orbit, and assesses the sensitivity of the processor to radiation exposure in low earth orbit. The MFE demonstrates a substantial advance in radiation hardened on-orbit computational performance, which is needed to handle the ever-increasing data load of modern imaging sensors and other orbital sensor systems. © 2016 IEEE.
