Inhibitors of Continuance Intention to Use Mobile Social Networking Sites: The Effects of Stress and Regret

This study aims at exploring factors influencing continuance intention to use mobile social networking sites (SNS). Specifically, this study attempts to investigate the effects of stress and regret. [Method /process] 226 valid data from working stuff were collected via questionnaires and further analyzed using SEM. [Result /conclusion] Results show that, stress and regret have significant impacts on continuance intention to use mobile SNS. Also, technology-work conflict and technology-personal conflict have significant influences on stress, and excessive use has a significant effect on regret

An LpL^p-primal-dual finite element method for first-order transport problems

A new $L^p$-primal-dual weak Galerkin method ($L^p$-PDWG) with $p>1$ is proposed for the first-order transport problems. The existence and uniqueness of the $L^p$-PDWG numerical solutions is established. In addition, the $L^p$-PDWG method offers a numerical solution which retains mass conservation locally on each element. An optimal order error estimate is established for the primal variable. A series of numerical results are presented to verify the efficiency and accuracy of the proposed $L^p$-PDWG scheme.Comment: 26 pages, 7 figures, 10 tables. arXiv admin note: text overlap with arXiv:1906.0733

Stability and Boundedness of Stochastic Volterra Integrodifferential Equations with Infinite Delay

We make the first attempt to discuss stability and boundedness of solutions to stochastic Volterra integrodifferential equations with infinite delay (IDSVIDEs). By the Lyapunov-Krasovskii functional approach, we get kinds of sufficient criteria for stability and boundedness of solutions to IDSVIDEs. The main innovation here is that stochastic systems with infinite delay can retain stability and boundedness of corresponding deterministic systems under some conditions

Influence of the Process Parameters on the Formation of CaSO 4

This paper discussed the influence of the process parameters such as the temperature, the mixing ways, and the molar ratios of the reactants on the morphology of the CaSO4·2H2O precursors and the CaSO4·0.5H2O whiskers. The experimental results indicated that CaSO4·0.5H2O whiskers with a length of 80–310 μm and a width of 0.8–8.0 μm were produced at hydrothermal condition, using CaSO4·2H2O fine particles as the precursors which were formed by adding Na2SO4 solution into CaCl2 solution at 25°C at the molar ratio of Na2SO4 to CaCl2 being 0.5 : 1. A lower supersaturation and a higher [Ca2+]/[] molar ratio favored the formation of CaSO4·2H2O particles with small sizes and the hydrothermal synthesis of CaSO4·0.5H2O whiskers with high aspect ratios
