- Ideally, both ecosystem service and human development policies should improve human well-being through the conservation of ecosystems that provide valuable services. However, program costs and benefits to multiple stakeholders, and how they change through time, are rarely carefully analyzed. We examine one of China's new ecosystem service protection and human development policies: the Relocation and Settlement Program of Southern Shaanxi Province (RSP), which pays households who opt voluntarily to resettle from mountainous areas. The RSP aims to reduce disaster risk, restore important ecosystem services, and improve human well-being. We use household surveys and biophysical data in an integrated economic cost-benefit analysis for multiple stakeholders. We project that the RSP will result in positive net benefits to the municipal government, and to cross-region and global beneficiaries over the long run along with environment improvement, including improved water quality, soil erosion control, and carbon sequestration. However, there are significant short-run relocation costs for local residents so that poor households may have difficulty participating because they lack the resources to pay the initial costs of relocation. Greater subsidies and subsequent supports after relocation are necessary to reduce the payback period of resettled households in the long run. Compensation from downstream beneficiaries for improved water and from carbon trades could be channeled into reducing relocation costs for the poor and sharing the burden of RSP implementation. The effectiveness of the RSP could also be greatly strengthened by early investment in developing human capital and environment-friendly jobs and establishing long-term mechanisms for securing program goals. These challenges and potential solutions pervade ecosystem service efforts globally.

Early-Life Exposure to Tap Water and the Development of Cognitive Skills
- 2022
-
In: Journal of Human Resources. - 0022-166X .- 1548-8004. ; 57:6, s. 2113-2149

Journal article (peer-reviewed)abstract
- We examine the impact of early-life exposure to tap water on children’s cognitive skills in later life. We exploit the variation in the timing of tap water connections across communities imposed by a major drinking water safety program in rural China. Using data extracted from the China Family Panel Studies, we find that one additional year of exposure to tap water in early life increases the cognitive test score at ages 10–15 by 0.132 standard deviations. The event study estimates confirm that the beneficial impacts of tap water exposure are concentrated in early life.

Lie Detection Using fNIRS Monitoring of Inhibition-Related Brain Regions Discriminates Infrequent but not Frequent Liars
- 2018
-
In: Frontiers in Human Neuroscience. - : Frontiers Media S.A.. - 1662-5161. ; 12
-
Journal article (peer-reviewed)abstract
- Functional near-infrared spectroscopy (fNIRS) was used to test whether monitoring inhibition-related brain regions is a feasible method for detecting both infrequent liars and frequent liars. Thirty-two participants were divided into two groups: the deceptive group (liars) and the non-deceptive group (ND group, innocents). All the participants were required to undergo a simulated interrogation by a computer. The participants from the deceptive group were instructed to tell a mix of lies and truths and those of the ND group were instructed always to tell the truth. Based on the number of deceptions, the participants of the deceptive group were further divided into a infrequently deceptive group (IFD group, infrequent liars) and a frequently deceptive group (FD group, frequent liars). The infrequent liars exhibited greater neural activities than the frequent liars and the innocents in the left middle frontal gyrus (MFG) when performing the deception detection tasks. While performing deception detection tasks, infrequent liars showed significantly greater neural activation in the left MFG than the baseline, but frequent liars and innocents did not exhibit this pattern of neural activation in any area of inhibition-related brain regions. The results of individual analysis showed an acceptable accuracy of detecting infrequent liars, but an unacceptable accuracy of detecting frequent liars. These results suggest that using fNIRS monitoring of inhibition-related brain regions is feasible for detecting infrequent liars, for whom deception may be more effortful and therefore more physiologically marked, but not frequent liars.

Innovations in science, technology, engineering, and policy (iSTEP) for addressing environmental issues towards sustainable development
- 2024
-
In: The Innovation Geoscience. - : Innovation Press. - 2959-8753. ; 2:3
-
Journal article (peer-reviewed)abstract
- Sustainable development depends on the integration of the economy, society, and environment. Yet, escalating environmental challenges pose threats to both society and the economy. Despite progress in addressing environmental issues to promote sustainability, knowledge gaps in scientific research, technological advancement, engineering practice, and policy development persist. In this review, we aim to narrow these gaps by proposing innovation-based solutions and refining existing paradigms. Reviewing past research and actions, we first elucidate the evolution of sustainability science and the essence of sustainable development and its assessment. Secondly, we summarize current major environmental issues, including global warming and climate change, biodiversity loss, land degradation and desertification, and environmental pollution, as well as their relationships with sustainability and the achievement of Sustainable Development Goals (SDGs). Subsequently, this review critically evaluates the role of innovations in science, technology, engineering, and policy (iSTEP) and their synergies in advancing sustainability and SDGs. While their sequential relationships may vary based on specific contexts or sustainability scenarios within the iSTEP framework, each component reinforces the others, fostering continuous improvement. Finally, this review offers recommendations and future perspectives for formulating sustainability roadmaps. Recommendations include fostering a vision of sustainability, promoting interdisciplinary collaboration, and encouraging transboundary cooperation among stakeholders for future sustainability endeavors.

Are Friends of My Friends Too Social? Limitations of Location Privacy in a Socially-Connected World

Conference paper (peer-reviewed)abstract
- With the ubiquitous adoption of smartphones and mobile devices, it is now common practice for ones location to be sensed, collected and likely shared through social platforms. While such data can be helpful for many applications, users start to be aware of the privacy issue in handling location and trajectory data. While some users may voluntarily share their location information (e.g., for receiving location-based services, or for crowdsourcing systems), their location information may lead to information leaks about the whereabouts of other users, through the co-location of events when two users are at the same location at the same time and other side information, such as upper bounds of movement speed. It is therefore crucial to understand how much information one can derive about others positions through the co-location of events and occasional GPS location leaks of some of the users. In this paper we formulate the problem of inferring locations of mobile agents, present theoretically-proven bounds on the amount of information that could be leaked in this manner, study their geometric nature, and present algorithms matching these bounds. We will show that even if a very weak set of assumptions is made on trajectories patterns, and users are not obliged to follow any reasonable patterns, one could infer very accurate estimation of users locations even if they opt not to share them. Furthermore, this information could be obtained using almost linear-time algorithms, suggesting the practicality of the method even for huge volumes of data.
