The reform era began with the removal of Mao-era elites from leadership positions on a scale theretofore unseen in the People's Republic of China. Rather than depending on incentives to mobilize Mao-era cadres to support Reform and Opening, the new reform leadership brought in younger, better educated pro-reform elites. This article thus proposes a Personnel Model, in which the Communist Party brings in sympathetic cadres to implement major shifts in the Party line. Furthermore, personnel changes were first imposed on the military, then on the civilian apparatus. We show the large scale and rapid implementation of these reforms in 1982–1984 using an original database of over 60,000 cadres drawn from Organizational Histories.

A long tradition in social sciences scholarship has established that kinship-based institutions undermine state building. I argue that kinship networks, when geographically dispersed, cross-cut local cleavages and align the incentives of self-interested elites in favor of building a strong state, which generates scale economies in providing protection and justice throughout a large territory. I evaluate this argument by examining elite preferences related to a state-building reform in eleventh century China. I map politicians’ kinship networks using their tomb epitaphs and collect data on their political allegiances from archival materials. A statistical analysis demonstrates that a politician’s support for state building increases with the geographic size of his kinship network, controlling for a number of individual, family, and regional characteristics. My findings highlight the importance of elite social structure in facilitating state development and help to advance our understanding of state building in China—a useful, yet understudied, counterpoint to the Eurocentric literature.

Authoritarian leaders around the world often fight against corruption in an effort to win public support. Conventional wisdom holds that this strategy works because leaders can signal their benevolent intentions by removing corrupt officials. We argue that fighting against corruption can undermine regime support. By revealing scandals of corrupt officials, corruption investigations can alter citizens' beliefs about public officials and lead to disenchantment about political institutions. We test this argument by examining how China's current anti-corruption campaign has changed citizens' public support for the government and the Communist Party. We analyze the results of two original surveys conducted before and during the campaign, and employ a difference-in-differences strategy to show that corruption investigations, at the margin, suppress respondents' support for the central government and party. We also examine our respondents' prior and posterior beliefs, and the results support our updating mechanism.

Mesanophrys sp. is a newly identified parasitic ciliate infecting farmed swimming crab. To demonstrate the correlation between parasite development and environmental conditions, this study aimed to investigate the effect of temperature, salinity, pH and frequency of passage of parasite on survival, growth and body size of Mesanophrys sp. in vitro. The results revealed that survival, population density and growth rate of the parasite were highest at 12°C and decreased with increasing temperature from 16 to 26°C. In addition, the survival, population density and growth rate of Mesanophrys sp. were high at 20‰. When salinity was adjusted to levels lower (0–10‰) and higher (40–60‰) than 20‰, the parasite's survival and growth rate gradually declined. The optimal pH for parasite survival was 8.0, whereas its survival was inhibited at <4.5 or >9.5. Our result also showed that parasite body proportions (length:width) were significantly smaller at the highest temperature compared to the lower temperature, whereas different salinities had no significant effect. Furthermore, we introduced dynamic parasite culture systems in vitro where Mesanophrys sp. was cultured in medium-containing culture plates through continually reducing and halving the old medium into fresh. Application of this optimized dilution timing technique with fresh medium and sub-cultured enabled a continuous culture of parasites. Under this optimized condition, the highest population density and exponential growth rate of the parasite were achieved than that of a control group. This study will help to understand the ciliated parasite infection dynamics and provides new possibilities for in vitro parasite-associated studies.

Autocrats use repression to deter opposition. Are they successful in the long run? The author argues that state repression can have long-lasting alienating effects on citizens’ political attitudes and coercive effects on their political behavior. The article evaluates this proposition by studying the long-term effects of state terror during China's Cultural Revolution. It shows that individuals who grew up in localities that were exposed to more state-sponsored violence in the late 1960s are less trusting of national political leaders and more critical of the country's political system today. These anti-regime attitudes are more likely to be passed down to the younger generation if family members discuss politics frequently than if they do not. Yet while state repression has created anti-regime attitudes, it has decreased citizens’ contentious behavior. These findings highlight the dilemma that authoritarian rulers face when they seek to consolidate their rule through repression.

Mammalian neonates undergo rapid transitions from a sterile uterine environment with a continuous intravenous supply of nutrients to a microbe-rich environment with intermittent ingesting of colostrum/milk via the gut. Currently, little is known about the colostrum-induced alterations of intestinal mucosal proteins in piglets with intra-uterine growth restriction (IUGR). In this study, we sought to investigate the innate differences and effects of colostrum on alterations in small-intestinal proteomes of IUGR piglets. Two IUGR (approximately 0·9 kg) and two normal-birth weight (NBW; approximately 1·3 kg) piglets were obtained from each of six sows at birth. One half (n 12; 6 IUGR v. 6 NBW) of the selected newborn piglets were killed to obtain jejunum samples, and the other half (n 12; 6 IUGR v. 6 NBW) of the newborn piglets were allowed to suckle colostrum from their own mothers for 24 h before jejunum sample collection. On the basis of proteomic analysis, we identified thirty-one differentially expressed proteins in the jejunal mucosa between IUGR and normal neonates before or after colostrum consumption. The intestinal proteins altered by colostrum feeding play important roles in the following: (1) increasing intestinal integrity, transport of nutrients, energy metabolism, protein synthesis, immune response and, therefore, cell proliferation; and (2) decreasing oxidative stress, and therefore cell apoptosis, in IUGR neonates. However, colostrum only partially ameliorated the inferior status of the jejunal mucosa in IUGR neonates. These findings provide the first evidence in intestinal protein alterations of IUGR neonates in response to colostrum ingestion, and thus render new insights into the mechanisms responsible for impaired growth in IUGR neonates and into new nutritional intervention strategies.

The development of highly efficient and stable inexpensive catalysts for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) by NaBH4 in an aqueous solution by utilizing metal-organic frameworks (MOFs) as precursor and template remains a hot topic. Herein, a simple self-template strategy was developed to synthesize a porous nitrogen-doped carbon frameworks embedded with zinc and cobalt nanoparticles (Zn0.3Co2.7@NC) catalyst by thermal annealing of the bimetallic zinc-cobalt zeolitic imidazolate framework (Zn0.3Co2.7-ZIF) as an effective precursor and template. The resulting Zn0.3Co2.7@NC catalysts show an excellent catalytic activity for the reduction of 4-NP and the reduction reaction was completed only in 5 min with nearly 100% conversion. The apparent rate constant for the reaction of 4-NP reduction was estimated to be 0.683 min−1. Moreover, the catalyst was extended to reduce other nitro compounds and exhibited excellent catalytic activity. When compared to other related catalysts in the literature, the catalytic activity of catalyst is superior. Therefore, the resulting Zn0.3Co2.7@NC is expected to get more extensive application in the field of catalysis.

I conduct an event study of an exogenous pollution shock-smog in the winter of 2013 to examine how the market values of firms in polluting industries and environmental protecting industries, respectively, responded in “the world's worst polluter”: China. I first show that politically connected polluters, defined by having at least one board member who was a former local bureaucrat, are more likely to be state owned and in debt. During the 21 days of the smog, polluters experienced a cumulative abnormal return of −5.38%, while protectors had a cumulative abnormal return of 3.50%. However, politically connected polluters were less susceptible to the shock: they experienced a 1% greater positive abnormal return than unconnected polluters. Connected protectors also benefited from a greater 1% abnormal return than unconnected protectors. The findings imply that environmental disasters have distributional effects, and support a theory that links rent-seeking behavior to pollution.

This article presents a large-scale, systematic study of politically connected firms in China. It was conducted by compiling a database of all the publicly traded firms in China in 1993, 2002 and 2012 that codes the biographies of hundreds of thousands of board members. I find that there has been a significant increase in the percentage of firms that are connected with the national government in the last 20 years. This casts doubt on a popular argument that businesses in China have primarily relied on “local protectionism.” I interpret this as a result of firms' need to connect with powerful and stable institutions. I test this by examining the impact of the fall of Chen Liangyu on firms in Shanghai.

Three-dimensional (3D) density distribution of inhomogeneous dense deuterium tritium plasmas in laser fusion is revealed by the energy loss of fast protons going through the plasmas. The fast protons generated in the laser–plasma interaction can be used for the simulation of a plasma density diagnostics. The large linear and ill-posed equation set of the densities of all grids is obtained and then solved by the Tikhonov regularization method after dividing a 3D area into grids and knowing the initial and final energies of the protons. 3D density reconstructions with six proton sources are done without and with random noises added to the final energy. The revealed density is a little smaller than the simulated one in most simulated zones and the error is as much as those of 2D reconstructions with four proton sources. The picture element N is chosen as 2744 with consideration of smoothness and calculation memory of the computers. With fast calculation speed and low error, the Tikhonov regularization method is more suitable for 3D density reconstructions with large calculation amount than simultaneous iterative reconstruction method. Also the analytical expressions between the errors and the noises are established. Furthermore, the density reconstruction method in this paper is particularly suitable for plasmas with small density gradient. The errors without noises and with 2% noises added to the final proton energies are 3 and 20%, respectively, for the homogeneous plasma.

Over the past two decades, the Chinese domestic security apparatus has expanded dramatically. “Stability maintenance” operations have become a top priority for local Chinese authorities. We argue that this trend goes back to the early 1990s, when central Party authorities adopted new governance models that differed dramatically from those of the 1980s. They increased the bureaucratic rank of public security chiefs within the Party apparatus, expanded the reach of the Party political-legal apparatus into a broader range of governance issues, and altered cadre evaluation standards to increase the sensitivity of local authorities to social unrest. We show that the origin of these changes lies in a policy response to the developments of 1989–1991, namely the Tiananmen democracy movement and the collapse of communist political systems in Eastern Europe. Over the past twenty years, these practices have developed into an extensive stability maintenance apparatus, whereby local governance is increasingly oriented around the need to respond to social unrest, whether through concession or repression. Chinese authorities now appear to be rethinking these developments, but the direction of reform remains unclear.
