High Resolution Image Download MS PowerPoint Slide We have studied gate hysteresis of carbon nanotube field-effect transistors (CNFETs) on silicon oxide substrates in an ultrahigh vacuum (UHV) at low temperatures. It is found that the hysteresis is neither reduced by thermal annealing at temperatures over 300 °C under UHV nor significantly affected by independent adsorption of ammonia or water at T = 56 K. However, the hysteresis decreases greatly upon coadsorption of water and ammonia below con

Marketing managers often face dilemmas when their athlete endorsers are accused of immoral behavior. However, research findings have been equivocal as to whether athletes’ transgressions damage endorsed brand evaluations. Using two experiments, we empirically demonstrate that consumers’ moral reasoning (i.e., moral rationalization, moral coupling, and moral decoupling) has differential effects on evaluations of a transgressor (Study 1). In Study 2, we examine the causal effect of moral reasoning

Athlete endorsers’ transgressions pose a dilemma for loyal fans who have established emotional attachments toward the individual. However, little is known regarding how fans maintain their support for the wrongdoer. Drawing on moral psychology and social identity theory, the current study proposes and examines a conceptual model incorporating athlete identification, moral emotions, moral reasoning strategies, and consumer evaluations. By using an actual scandal involving an NFL player (i.e., Ray

In order to broaden our knowledge of the primary immune responses to respiratory syncytial virus (RSV) and adenovirus infections, we compared the concentrations of interleukin (IL)-6, IL-8, and regulated on activation, normal T cell expressed and secreted (RANTES) produced in vitro during RSV and adenovirus infections of bronchial epithelial cells. We infected BEAS-2B cells-a human bronchial epithelial cell line-with RSV, adenovirus serotype 3, or serotype 7 and measured the concentrations of IL

A series of sol-gel-processed lanthanum-modified lead zirconate titanate (PLZT) thin films with La/Zr/Ti ratios of 8.5/65/35, 9/65/35, 9.5/65/35, 15.5/40/60 and 18/30/70 were prepared on indium tin oxide (ITO)-coated Corning 7059 glass substrates and heat-treated at different temperatures from 475° C to 685° C. The X-ray diffraction, microstructure, optical transmittance spectra and the polarization vs electric field curves were investigated. The P(L)ZT thin films of higher Ti/Zr ratio show lowe

•On-field and off-field transgressions have differential damage on two-dimensional trust evaluations.•Engaging in prosocial actions is more effective than outstanding performance in repairing transgressor’s trust.•Integrity-based trust is the key determinant in generating consumer forgiveness of the transgressor.A celebrity athlete’s transgression damages the public’s trust in that celebrity. However, little is known about whether demonstrating an outstanding performance after the transgression

Various haematological and immunological studies on patients infected with Plasmodium vivax were undertaken, at diagnosis (day 0), after treatment with chloroquine but during primaquine treatment (day 10) and after all treatment (day 59), in South Korea (where there has been a recent and abrupt increase in the incidence of such infection). The main aims were to gain an understanding of the haemto-immunological alterations of this malarial infection, both before and after treatment, and to identi

The direct reaction of trimethylaluminum (TMA) on a Ge(100) surface and the effects of monolayer H(2)O pre-dosing were investigated using ultrahigh vacuum techniques, such as scanning tunneling microscopy (STM), scanning tunneling spectroscopy (STS), and x-ray photoelectron spectroscopy (XPS), and density functional theory (DFT). At room temperature (RT), a saturation TMA dose produced 0.8 monolayers (ML) of semi-ordered species on a Ge(100) surface due to the dissociative chemisorption of TMA.

•Pre-transgression athlete philanthropy mitigates negative impact of the transgression on consumer responses.•The deeper commitment to charitable behavior leads to better protection compared to the simple support for a cause.•Higher fit between a transgressed athlete and a cause results in more negative consumer responses due to consumer skepticism.Despite the importance of an athlete’s image and reputation as an individual brand, the academic literature lacks investigations on whether and how a
