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

Work Motivation and Performance Appraisal: The Chinese College Instructors Perceived Procedural Fairness of Moderating Effect

This article aimed to clarify the mechanism of performance appraisal on college instructors’ teaching and research performance by constructing a moderated mediation model. By surveying 407 Chinese public college instructors on the performance appraisal model, work motivation, job (teaching and research) performance, and procedural fairness using a questionnaire, the research performed descriptive and regression analyses. It is the first time to explore the impact of different performance appraisal on college instructors’ teaching and research performance through empirical methods, which enriches the theoretical literature of performance appraisal, and has guiding role for college to reasonably determine instructors’ performance appraisal model, indicators and methods. The results showed that: (1) Performance appraisal and work motivation positively affect college instructors’ teaching and research performance. (2) Intrinsic motivation plays a mediating role in the relationship between developmental assessment and job performance;extrinsic motivation mediates evaluative assessment and teaching performance. (3) The direct effect of performance appraisal on instructors’ job performance and the mediating effect of work motivation on the relationship between them are moderated by the perceived fairness of the performance appraisal procedure. These findings help understand the relationship and mechanism between faculty performance appraisal and job performance, enlightening the rational use of performance appraisal in higher education

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

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

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
