The optimal logistics service strategy choices between the platform and e-retailers
Liu Tianzhuo, Huang Rong, Yang Feng, Wang Manman
2021, 51(4): 259-274. doi: 10.52396/JUST-2021-0081
Abstract:
In the e-commerce market, the success of the hybrid online platform is well proven. The platform is not only an e-retailer but also provides online logistics services for other e-retailers in the platform. Logistics service is an indispensable link in e-commerce, and it also plays a vital role in pr...
Vocational interests and informal learning in the workplace: The mediating role of goal orientation
Weng Qingxiong, Chen Chen, Li Junyi, Niu Tingting
2021, 51(4): 275-287. doi: 10.52396/JUST-2020-0030
Abstract:
We used the social cognitive career theory to investigate how vocational interests affect informal learning behavior in the workplace by building a model with three different dimensions of vocational interests as independent variables and different goal orientation dimensions as mediating variables....
Corporate resistance to pandemic: Evidence from China
Li Tingfang, Wang Xiao
2021, 51(4): 288-298. doi: 10.52396/JUST-2021-0070
Abstract:
Based on the quarterly data of A-share listed firms between 2019 and 2020, we find that firms with lower leverage and higher cash holdings before perform better under the COVID-19 pandemic, suggesting that strong liquidity helps firms resist risks. In particular, cash holding affects firm performanc...

Plane microscopic observation on instability of double emulsion clusters
Zhang Zhanhao, Qiu Yuheng, He Dongliang, He Liqun
2021, 51(4): 299-307. doi: 10.52396/JUST-2020-0023
Abstract:
Double emulsions have huge potential applications in many fields, but their wide use is limited by the instability. We have established a plane experimental observation method based on the microscope observation on the instability of double emulsion clusters to understand the key factors that affect...
The performance analysis on a novel purified PV-Trombe wall for electricity, space heating, formaldehyde degradation and bacteria in activation
Li Niansi, Liu Xiaoyong, Yu Bendong
2021, 51(4): 308-318. doi: 10.52396/JUST-2020-0018
Abstract:
On the one hand, PV-Trombe wall is a combined solar system that meets dual functions of space heating and electricity output, but the utilization on the recovered solar heat by PV-Trombe wall is very limited. On the other hand, thermal catalytic oxidation and thermal sterilization are two advanced a...
Development of the Ag nanoparticle-decorated Co3O4 electrode for high-performance hybrid Zn batteries
Shang Wenxu, Yu Wentao, Ma Yanyi, Tan Peng
2021, 51(4): 319-326. doi: 10.52396/JUST-2021-0049
Abstract:
The hybrid Zn battery is a promising electrochemical system integrating the redox reactions of transition metal oxides and oxygen in a single cell, through which high energy efficiency and energy density can be achieved simultaneously. However, the positive electrode usually suffers from unsatisfact...

Estimation based approximating control for wireless networked control systems
Liang Qipeng, Zhu Qiaohui, Kang Yu, Zhao YunBo
2021, 51(4): 327-334. doi: 10.52396/JUST-2020-1156
Abstract:
The control design and system analysis of wireless networked control systems with unknown round-trip delay characteristics are investigated. An estimation based approximating control strategy is proposed to stabilize the systems by using delay characteristics in a practically feasible way. The strat...
