Culture and deception in business negotiations : A multilevel analysis

Abstract: This article investigates the relationship between culture, personality, and deception in a simulated international management negotiation at multiple levels of analysis. `Deception' was operationalized here as the propensity to lie and bribe. As predicted, at the cultural level the results from a scenario study with 1583 participants from eight cultures suggested that cultural collectivism was positively related to reported use of deception in negotiations, and to greater emotional reactions (i.e. guilt, shame, and disgust) after the use of deception. At the individual level, however, the personality variable of allocentrism (consisting of behaviors found in collectivist cultures) was negatively related to the use of deception. Theoretical implications are discussed.

On compensating nonlinear distortions of an OFDM system using an efficient adaptive predistorter

Abstract: This paper presents an efficient adaptive predistortion technique compensating for nonlinear distortions caused by a high-power amplifier (HPA) cascaded with a linear filter in an OFDM system. In the proposed approach, the memoryless HPA, preceded by a linear filter with memory in OFDM systems, is modeled by the Wiener system, which is then precompensated by the proposed adaptive predistorter with a minimum number of filter taps. It is confirmed by computer simulation that the proposed approach produces a faster convergence speed than the previous adaptive predistortion technique, and provides a small output backoff as low as 5.5 dB for an OFDM system employing an HPA with a linear filter.

Transition from Diffusion‐Controlled Intercalation into Extrinsically Pseudocapacitive Charge Storage of MoS2 by Nanoscale Heterostructuring

Abstract: 2D nanomaterials have been found to show surface-dominant phenomena and understanding this behavior is crucial for establishing a relationship between a material's structure and its properties. Here, the transition of molybdenum disulfide (MoS2) from a diffusion-controlled intercalation to an emergent surface redox capacitive behavior is demonstrated. The ultrafast pseudocapacitive behavior of MoS2 becomes more prominent when the layered MoS2 is downscaled into nanometric sheets and hybridized with reduced graphene oxide (RGO). This extrinsic behavior of the 2D hybrid is promoted by the fast Faradaic charge-transfer kinetics at the interface. The heterostructure of the 2D hybrid, as observed via high-angle annular dark field–scanning transmission electron microscopy and Raman mapping, with a 1T MoS2 phase at the interface and a 2H phase in the bulk is associated with the synergizing capacitive performance. This 1T phase is stabilized by the interactions with the RGO. These results provide fundamental insights into the surface effects of 2D hetero-nanosheets on emergent electrochemical properties.
