Abstract

AbstractLive streaming has been increasingly popular worldwide, with gift-giving emerging as a pivotal revenue stream for many streamers. While prior research has delved into the influence of streamers’ emotions and viewer-streamer interaction on viewers’ gift-giving behaviors, we suggest that peer viewers also play an essential role. In line with the principles of social influence and herding theory, the behaviors of peer viewers and the size of the viewing group are integral factors shaping individual behaviors. Hence, in the context of lives streaming, we focus on examining the impact of peer viewers’ gift-giving behaviors and the audience size on the gift-giving behaviors of individual viewers, respectively. Additionally, we examine the moderating role of viewers’ identities. We collected data from a popular live streaming platform in China and employed a panel regression model based on a sample of 651,678 viewers. This study contributes to the gift-giving literature by revealing the influence of peer viewers on focal viewers’ likelihood of gifting, gifting frequency and gifting value, and the moderating effect of viewers’ identities. Overall, these results have significant implications for both the theoretical understanding of social influence and herding in online setting, as well as the practical implications for future live streaming management. Future research could delve deeper into understanding the impact of various types of live streaming content and cultural differences on individual’s gift-giving behavior. [ABSTRACT FROM AUTHOR]

Abstract

The temperature is a very important parameter for an operating vanadium redox flow battery (VRFB). During charging and discharging, the temperature of VRFB is constantly changing. In this paper, a self‐made 35 kW vanadium stack was charged & discharged at the current density of 100 and 120 mA cm−2 to investigate the change trend of real‐time operating temperature. The results show that the temperature decreases during charging and increases during discharging. And the average temperature of each cycle increases with continuous charge‐discharge cycles. The influences of real‐time temperature on performance of columbic efficiency (CE), voltage efficient (VE), over‐potential, capacity, energy, state of charge (SOC), and pressure loss were further investigated. The results show that the temperature fluctuation largely affects the electrochemical properties of VRFB. With the real‐time average temperature increased from 16.02 °C to 29.91 °C, the VE, capacity, energy and the SOC range of the battery increased, while the CE, the over‐potential and the average pressure loss decreased. This work not only gives data support to temperature management of VFB, but also provides direction to the engineering application of all flow batteries. [ABSTRACT FROM AUTHOR]

Abstract

The main purpose of the present study was to assess the beneficial effect of Lactobacillus plantarum GM11 (LacP GM11), screened from Sichuan traditional fermented food, in depressive rats induced by chronic unpredictable mild stress (CUMS). Male SPF SD rats were randomly assigned to 3 groups: the control group, CUMS group and CUMS + LacP GM11 group (n = 10). The rats in the CUMS and LacP GM11 groups received CUMS stimulation for 42 d. The behavioral tests and levels of monoamine neurotransmitter, glucocorticoid hormone and brain-derived neurotrophic factor (BDNF) in the serum and hippocampus were measured. The effects of LacP GM11 on the mRNA and protein expression of BDNF and cAMP response element binding protein (CREB) in the hippocampus were also investigated. After supplementation for 21 d, LacP GM11 was associated with alleviation of depressive-like behavior, not anxiety-like behavior, in depressive rats. LacP GM11 increased the levels of 5-hydroxytryptamine (5-HT) and BDNF and decreased the level of cortisol (CORT) in the serum and hippocampus in depressed rats. In addition, treatment with LacP GM11 also increased the mRNA and protein expression of BDNF and CREB in the hippocampus. This work has revealed that LacP GM11 has potential beneficial effects on depression. This effect might be related to alleviating monoamine neurotransmitter deficiency, HPA axis hyperfunction and CREB-BDNF signaling pathway downregulation. This study demonstrates that LacP GM11 could be a potential therapeutic approach to treat depression and other mental health problems. [ABSTRACT FROM AUTHOR]
