Mainstream blockchain systems such as Bitcoin and Ethereum are revolutionizing the financial industry by adopting the Nakamoto consensus protocol, i.e., Proof-of-Work (PoW). Only nodes with sufficient computing resources can work out the PoW difficulties, ...

Competitive elements are a common feature of many game jams. However, there has been little research to date on the impact of competition on participants and their behaviours. To better understand how incentives and competition may affect the ...

Portfolio risk taking when periodic performance matters

Incentives of portfolio managers in real life are typically tied to their periodic performance—a criterion that has received very little attention to date. How does the repeated nature of the rewards ...

We present a continuous-time portfolio selection problem faced by an agent with S-shaped preference who maximizes the utilities derived from the portfolio’s periodic performance over an infinite horizon. The periodic reward structure creates subtle ...

The purpose of this paper is to explore the factors that influence the e-payment behaviour of Macao's young citizens. The mediating effect of intention between certain factors and adoption of e-payment is also considered. This study develops a conceptual ...

Small and medium-sized enterprises (SMES) in China, especially knowledge-based enterprise is one of the main forces for realizing knowledge innovation and changing industrial structure, and creation, utilization and appreciation of the knowledge ...

Mobile crowdsensing (MCS) is a technique where individuals voluntarily utilise their devices to collect data to measure phenomena. In this article, a review of privacy-preserving in MCS is presented. First, it highlights MCS definitions, architecture, and ...

We conducted a field experiment to identify the causal effect of extrinsic reward cues on the sorting and performance of nascent social entrepreneurs. The experiment, carried out with one of the United Kingdom’s largest support agencies for social ...

Proof-of-Work (PoW) is the most widely adopted incentive model in current blockchain systems, which unfortunately is energy inefficient. Proof-of-Stake (PoS) is then proposed to tackle the energy issue. The rich-get-richer concern of PoS has been ...

Open Source Software (OSS) has changed drastically over the last decade, with OSS projects now producing a large ecosystem of popular products, involving industry participation, and providing professional career opportunities. But our field's ...

We present a novel mechanism to enhance participatory crowdsensing for smart transportation by integrating privacy-preserving data filtering, aggregation and incentive-driven dissemination. Our mechanism filters out inaccurate data before computing the ...

We have built and implemented a set of metaphors for breathing games by involving children and experts. These games are made to facilitate prevention of asthma exacerbation via regular monitoring of children with asthma through spirometry at home. To ...

This paper consists of two parts. In the second part, the management mechanisms for implementing complex projects that improve the energy-saving characteristics of products and technologies are further studied. An incentive model for saving energy ...

With the remarkable proliferation of smart mobile devices, mobile crowdsensing has emerged as a compelling paradigm to collect and share sensor data from surrounding environment. In many application scenarios, due to unavailable wireless network or ...

This paper introduces an empirical study focusing on task settings similar to those in the real-world that captures user behavioral information of fine granularity. In online experiments, participants recruited from the Mechanical Turk human subject ...

In a contest in which solvers with heterogeneous expertise exert effort to develop solutions, a recent paper [Terwiesch C, Xu Y 2008 Innovation contests, open innovation, and multiagent problem solving. Management Sci. 549:1529-1543] argues that as more ...

Peer-reviewing is a community-driven activity where volunteer researchers assess the work of other researchers. Peer-reviewing is an important and time-consuming activity that has very little recognition. This lack of incentive may lead to poor-quality ...

Although people generally try to avoid lying, the lure of potential monetary payoffs often leads to unethical behavior. The current research investigates whether small monetary rewards for honesty help people resist the temptations of larger incentives ...

Predictive modeling is fundamental in transforming large clinical data sets into actionable knowledge which can guide clinical decision making and personalized medicine. Although several studies have merged data mining techniques with statistical ...

Deadlines are common in product development and are often felt to be too harsh-many development efforts are still worth continuing at the time of mandated termination. We examine the value of deadlines from the agency-theoretic perspective. We consider ...
