In the course of China's rapid urbanization, rural places are brought into urban areas, forming semi-urbanization. These semi-urbanized sites suggest a dual urban–rural structure in their form and management. With the slowing down of urbanization, the Chinese government adopted heritage tourism to boost the local economy. Local historic buildings and cultural resources were regenerated and restored in this process. This paper aims at examining the role of heritage tourism in blurring the boundary of rurality and urbanity, boosting local economy, and revitalizing the areas with cultural-led development. In this paper, we analyzed the Huangpu Ancient Village's regeneration process. We argue that the Huangpu Ancient Village integrates local historical and cultural resources to boost the local economy, simultaneously adopting urban renewal and rural revival strategies. This paper contributes to the body of literature addressing villages in urban areas, breaking the duality of urbanity and rurality.

Working paper
The last decade has seen considerable concern regarding a shortage of science, technology, engineering, and mathematics (STEM) workers to meet the demands of the labor market. At the same time, many experts have presented evidence of a STEM worker surplus. A comprehensive literature review, in conjunction with employment statistics, newspaper articles, and our own interviews with company recruiters, reveals a significant heterogeneity in the STEM labor market: the academic sector is generally oversupplied, while the government sector and private industry have shortages in specific areas.

The academic job market has become increasingly competitive for PhD graduates. In this note, we ask the basic question of 'Are we producing more PhDs than needed?' We take a systems approach and offer a 'birth rate' perspective: professors graduate PhDs who later become professors themselves, an analogue to how a population grows. We show that the reproduction rate in academia is very high. For example, in engineering, a professor in the US graduates 7.8 new PhDs during his/her whole career on average, and only one of these graduates can replace the professor's position. This implies that in a steady state, only 12.8% of PhD graduates can attain academic positions in the USA. The key insight is that the system in many places is saturated, far beyond capacity to absorb new PhDs in academia at the rates that they are being produced. Based on the analysis, we discuss policy implications. Copyright © 2013 John Wiley & Sons, Ltd.

The explosive increase in the number of postdocs in biomedical fields is puzzling for many science policymakers. We use our previously introduced parameter in this journal, the basic reproductive number in academia (R0), to make sense of PhD population growth in biomedical fields. Our analysis shows how R0 in biomedical fields has increased over time, and we estimate that there is approximately only one tenure‐track position in the US for every 6.3 PhD graduates, which means that the rest need to get jobs outside academia or stay in lower‐paid temporary positions. We elaborate on the structural reasons and systemic flaws of science workforce development by discussing feedback loops, especially vicious cycles, which contribute to over‐production of PhDs. We argue that the current system is unstable but with no easy solution. A way to mitigate the effects of strong reinforcing loops is full disclosure of the risks of getting PhD. © 2014 The Authors.
