    Advertising Creativity in Korea: scale development and validation

    No full text
    The authors develop and validate a measure of advertising creativity that is intended for a collectivistic, holistic population. Scale-development procedures result in a four-factor correlated model comprising originality, considerateness, clarity, and product relevance. The second dimension, considerateness, appears to mirror the culturally unique propensity to value the collectivistic Confucian norms of the society and the contextual elements of the advertisement. Reliability and validity of the scale are examined

    The Double-Edged Sword of Expert Reviewer Programs: The Effects of Offering Expert Reviewer Status on Review Generation

    No full text
    As online reviews play an increasingly influential role in consumer decisions in e-commerce, large online retailers such as Amazon recently launched expert reviewer programs to supply high-quality reviews by selected experts. While prior studies examined the impact of online reviews written by experts on the product’s sales performance, our study investigates the effects of soliciting users to join expert reviewer programs and offering free products on their review generation processes and outcomes. Contrary to the common wisdom, our results reveal that, after reviewers participate in expert reviewer programs, they generate longer reviews but offer lower ratings for sponsored free products. However, they produce more reviews and higher ratings for non-sponsored regular products. Additional analyses offer theoretical underpinnings for the asymmetric effects of expert reviewer programs

    Dual Binding to Orthosteric and Allosteric Sites Enhances the Anticancer Activity of a TRAP1-Targeting Drug

    The molecular chaperone TRAP1 is the mitochondrial paralog of Hsp90 and is overexpressed in many cancer cells. The orthosteric ATP-binding site of TRAP1 has been considered the primary inhibitor binding location, but TRAP1 allosteric modulators have not yet been investigated. Here, we generated and characterized the Hsp90 inhibitor PU-H71, conjugated to the mitochondrial delivery vehicle triphenylphosphonium (TPP) with a C-10 carbon spacer, named SMTIN-C10, to enable dual binding to orthosteric and allosteric sites. In addition to tight binding with the ATP-binding site through the PU-H71 moiety, SMTIN-C10 interacts with the E115 residue in the N-terminal domain through the TPP moiety and subsequently induces structural transition of TRAP1 to a tightly packed closed form. The data indicate the existence of a druggable allosteric site neighboring the orthosteric ATP pocket that can be exploited to develop potent TRAP1 modulators

    Nanoscale Pillar-Enhanced Tribological Surfaces as Antifouling Membranes

    We present a nonconventional membrane surface modification approach that utilizes surface topography to manipulate the tribology of foulant accumulation on water desalination membranes via imprinting of submicron titanium dioxide (TiO<sub>2</sub>) pillar patterns onto the molecularly structured, flat membrane surface. This versatile approach overcomes the constraint of the conventional approach relying on interfacial polymerization that inevitably leads to the formation of ill-defined surface topography. Compared to the nonpatterned membranes, the patterned membranes showed significantly improved fouling resistance for both organic protein and bacterial foulants. The use of hydrophilic TiO<sub>2</sub> as a pattern material increases the membrane hydrophilicity, imparting improved chemical antifouling resistance to the membrane. Fouling behavior was also interpreted in terms of the topographical effect depending on the relative size of foulants to the pattern dimension. In addition, computational fluid dynamics simulation suggests that the enhanced antifouling of the patterned membrane is attributed to the enhancement in overall and local shear stress at the fluid–TiO<sub>2</sub> pattern interface

    Securing the feedstock procurement for bioenergy products: a literature review on the biomass transportation and logistics

    No full text
    The importance of transportation and logistics in the biomass supply chain has been recognized, yet the specific research on those topics has been limited. This paper reviews the peer-reviewed literature to assess the current challenges, trends, and ideas in the biomass transportation and logistics research. All papers were selected based on three English keywords: transportation, logistics, and biomass. We addressed literature statistics per research category and then discussed four criteria that significantly influence the viability of the supply chain: transportation/logistics cost, shipping distance, plant capacity, and system efficiency. A brief review of industry literature was also conducted to identify topics potentially absent from the peer-reviewed literature. The study findings included the great variability of values used in the literature, both related to the fixed and variable costs of transportation and to the optimal shipping distance based on logistics conditions. From transportation mode and plant capacity perspective, we found that studies have concentrated on improving system efficiency of truck transportation for smaller plants while large plants have received less attention. The research gaps included the seemingly poor fit of typical logistics and supply chain frameworks with biomass systems. There is also a lack of sustainable transportation cost model to account for economic, environmental, and social factors. Finally, there is a need to explore the effects of feedstock conversion and upgrading options to biomass transportation logistics (BTL) and to combine the BTL studies with long-term biomass sourcing strategies to mitigate supply variations
