While monetary rewards have been widely used by online platforms to motivate user-generated content (UGC) contributions, users may not always demonstrate the expected behaviors. Unintended consequences of reward policies, exemplified by unchanged or reduced UGC contributions, may occur. Through two natural experiments, this study investigates the implications of providing users with an incentive structure that rewards users' continued contribution according to the volume of UGC. Using a unique data set on two completion-contingent incentive programs from a popular online aesthetic medicine platform, we examine user responses to reward thresholds. We found that after users reach a threshold to obtain a monetary reward, they are less likely to continue contributing UGC, suggesting a minimal-effort effect. Our findings indicate that social approval from peers helps to mitigate unintended user responses to monetary reward policies. We also observed that monetary rewards primarily improve the quality and website traffic of low- to moderate-quality contributions. [ABSTRACT FROM AUTHOR]

Switches play a critical role as core components in data center networks. The advent of multi-die chiplet packaging as a prevailing trend in complex chip development presents challenges in designing the multi-die packaging of switch chips. With limited inter-die connections in mind, we propose a scalable, unified switch architecture optimized for efficient connectivity. This architecture includes the strategic mapping of data queues, meticulous planning of data paths, and the integration of a unified interface, all aiming to facilitate efficient switch operations within constrained connectivity environments. Our optimization efforts encompass various areas, including refining arbitration strategies, managing mixed unicast and multicast transmissions, and mitigating network congestion to alleviate bottlenecks in data flow. These enhancements contribute to heightened levels of performance and robustness in the switching process. During the validation phase, the structure we propose reduced interconnection usage between dies by 25%, while supporting functions such as unicast and multicast transmissions.

In this paper, we examine pricing strategies in the U.S. online book industry over two time periods, with an aim to understand whether and how the driving factors of price dispersion change over time. Our empirical results show that dispersion in prices has remained substantial over the period of 2001-2006, but the driving factors of these variations in price have evolved. In 2001 online book retailers generally engaged in obfuscation, frustrating consumer search by manipulating shipping options. As documented by prior literature and revealed in our 2001 data, higher prices charged by retailers were positively related with longer shipping time. This strategy has been abandoned, as shown by our results of a 2006 sample. Online retailers are now competing to ship items quicker than rivals and to pass fewer or no shipping costs on to consumers. The impact of trust assurance seals (e.g., seals of online security and privacy) on price has materialized over the period of 2001-2006. This is because as more consumers become security conscious, the effects of assurance seals on the price becomes better recognized. Moreover, although retailers are roughly clustered into three cohorts, they strategize prices across different product items within each cohort. [ABSTRACT FROM AUTHOR]

Inconspicuous consumption – whereby brand signals are subtle, or not easily visible, to most consumers and the overt display of social status is sidestepped – is on the rise, even in China, which has typically favoured conspicuous brand signalling. Research on luxury brands tends to focus on conspicuous consumption, and few studies have explored the ways in which Chinese consumers use Chinese luxury brands in inconspicuous ways. This study examines how Chinese luxury consumers are redefining their identity projects, as well as their conceptions of luxury, in relation to inconspicuous consumption. We suggest that inconspicuous consumption encompasses consuming luxury products without overtly displaying wealth and social status. Thus, certain luxury brands enable inconspicuous consumption. Turning to a group of Chinese luxury brands offers insights into how luxury brands may fill this role for newly emerging forms of inconspicuous consumption. We distinguish four forms of inconspicuous consumption, illustrated by consumers (1) with wished-for identities or fantasy lifestyles, (2) who appreciate aesthetics and function, (3) who are wealthy and prefer not to provoke envy and/or anger in times of economic austerity and (4) who desire to differentiate themselves and employ subtle signals that are only observable to people with the requisite knowledge to decode their meaning. These forms of inconspicuous consumption facilitate the construction and display of one’s reflective identities, including privately fantasized identity, privately held identity and partially public reflective identities. Thus, we contribute to identity construction theory by explicating aspects of reflective identity and linking them to forms of inconspicuous consumption. Finally, we expand upon recent research on inconspicuous consumption by demonstrating how inconspicuous consumption is manifested in China – the largest luxury market. The results help redefine constructs in the paradoxical situation of inconspicuous consumption of luxury brands, adding a layer of complexity to the inconspicuous consumption concept.

The transport properties of polarons in a heterostructure are of great importance, since they can effectively affect the efficiency of photoelectric devices. However, the underlying mechanism of the polaron transfer rate and mode along intralayers or interlayers is still far from conclusive. Here, the stability and transport behaviors of polarons in polarized MoSSe few-layer structures were systematically investigated by constrained density functional theory (CDFT). It shows that the electron polarons in a MoSSe monolayer are more stable but have a smaller transfer rate than that of the hole polarons. Although the stability of the polarons will be slightly decreased by forming a parallel polarization heterostructure, the magnitude of the electron polaron transfer rate can be remarkably increased by 5 times and 71 times in their double- and three-layer case. In particular, it was unexpected to find that the original transfer mode along intralayer (in-plane) in monolayer can be completely overturned to along the interlayer (out-of-plane) by forming different stackings or increasing the MoSSe thickness. This unique behavior is strongly related to the polarization and the synergy effect of electronic coupling H αβ and reorganization energy λ . Our findings offer a new perspective for the application of Janus MoSSe structures in optoelectronic devices and further advancement in the field of polarized low-dimensional materials.
