  Title The role of class I integrons in the dissemination of sulfonamide resistance genes in the Pearl River and Pearl River Estuary, South China Type Journal Article
  Year 2015 Publication Journal of Hazardous Materials Abbreviated Journal J Hazard Mater  
  Volume 282 Issue Pages 61-67  
  Keywords Anti-Bacterial Agents/*analysis; Bacterial Proteins/genetics; China; DNA, Bacterial/analysis; Drug Resistance, Microbial/*genetics; Estuaries; *Genes, Bacterial; Geologic Sediments/analysis; *Integrons; RNA, Ribosomal, 16S/analysis; Rivers; Sulfonamides/*analysis; Water Pollutants/*analysis; Antibiotic resistance genes (ARG); Class 1 intergron, Pearl River Estuary (PRE); South China; Sulfonamide resistance genes (sul1, and sul2)  
  Abstract Antibiotic resistance genes (ARGs), as a newly emerging contaminant, are unique because they are disseminated through horizontal gene transfer in the environment. In the present study, a class 1 integron gene (int1) and various ARGs (sul1, sul2, sul3, qnrS, and ermB) were measured in water and sediment samples from the Pearl River (PR) to the Pearl River Estuary (PRE), where there is a distinct gradient in anthropogenic impact. The int1, sul1, and sul2 genes were detected in all samples, and their concentrations exhibited a clear trend of decline consistent with anthropogenic impact. Both the int1 and sul genes had dynamically migrated between water and sediments. The relative abundance of the int1 gene normalized to the 16S rRNA gene correlated significantly with the total concentrations of antibiotics in water and sediments. Good correlations were also observed between the abundance of int1 and each type of sul gene in the samples. However, the sul1 gene showed a much stronger relationship with int1 in different seasons, probably due to the presence of sul1 in the conserved region of class 1 integron. Our results strongly support that integrons play an important role in the dissemination of ARGs in human-impacted aquatic environments.

  Title Driver injury severity outcome analysis in rural interstate highway crashes: a two-level Bayesian logistic regression interpretation Type Journal Article
  Year 2016 Publication Accident; Analysis and Prevention Abbreviated Journal Accid Anal Prev  
  Volume 97 Issue Pages 69-78  
  Keywords Accidents, Traffic/*statistics & numerical data; Adolescent; Adult; Automobile Driving/*statistics & numerical data; Bayes Theorem; China; Female; Humans; Logistic Models; Male; Middle Aged; Models, Theoretical; *Rural Population; Safety/*statistics & numerical data; Seat Belts/utilization; Bayesian inference; Driver injury severity; Hierarchical model; Rural interstate highway; Traffic crash  
  Abstract There is a high potential of severe injury outcomes in traffic crashes on rural interstate highways due to the significant amount of high speed traffic on these corridors. Hierarchical Bayesian models are capable of incorporating between-crash variance and within-crash correlations into traffic crash data analysis and are increasingly utilized in traffic crash severity analysis. This paper applies a hierarchical Bayesian logistic model to examine the significant factors at crash and vehicle/driver levels and their heterogeneous impacts on driver injury severity in rural interstate highway crashes. Analysis results indicate that the majority of the total variance is induced by the between-crash variance, showing the appropriateness of the utilized hierarchical modeling approach. Three crash-level variables and six vehicle/driver-level variables are found significant in predicting driver injury severities: road curve, maximum vehicle damage in a crash, number of vehicles in a crash, wet road surface, vehicle type, driver age, driver gender, driver seatbelt use and driver alcohol or drug involvement. Among these variables, road curve, functional and disabled vehicle damage in crash, single-vehicle crashes, female drivers, senior drivers, motorcycles and driver alcohol or drug involvement tend to increase the odds of drivers being incapably injured or killed in rural interstate crashes, while wet road surface, male drivers and driver seatbelt use are more likely to decrease the probability of severe driver injuries. The developed methodology and estimation results provide insightful understanding of the internal mechanism of rural interstate crashes and beneficial references for developing effective countermeasures for rural interstate crash prevention.

  Title Emissions and temperature benefits: The role of wind power in China Type Journal Article
  Year 2017 Publication Environmental Research Abbreviated Journal Environ Res  
  Volume 152 Issue Pages 342-350  
  Keywords Air Pollution/*prevention & control; China; *Climate Change; Coal/analysis; Global Warming/prevention & control; Greenhouse Effect/*prevention & control; Models, Economic; Models, Theoretical; Power Plants; Renewable Energy; *Wind; *Climate integrated model; *Fossil fuel substitution; *Temperature benefits; *Wind energy  
  Abstract BACKGROUND: As a non-fossil technology, wind power has an enormous advantage over coal because of its role in climate change mitigation. Therefore, it is important to investigate how substituting wind power for coal-fired electricity will affect emission reductions, changes in radiative forcing and rising temperatures, particularly in the context of emission limits. METHODS: We developed an integrated methodology that includes two parts: an energy-economy-environmental (3E) integrated model and an emission-temperature response model. The former is used to simulate the dynamic relationships between economic output, wind energy and greenhouse gas (GHG) emissions; the latter is used to evaluate changes in radiative forcing and warming. RESULTS: Under the present development projection, wind energy cannot serve as a major force in curbing emissions, even under the strictest space-restraining scenario. China's temperature contribution to global warming will be up to 21.76% if warming is limited to 2 degrees. With the wind-for-coal power substitution, the corresponding contribution to global radiative forcing increase and temperature rise will decrease by up to 10% and 6.57%, respectively. CONCLUSIONS: Substituting wind power for coal-fired electricity has positive effects on emission reductions and warming control. However, wind energy alone is insufficient for climate change mitigation. It forms an important component of the renewable energy portfolio used to combat global warming.

  Title Would Confucius benefit from psychotherapy? The compatibility of cognitive behaviour therapy and Chinese values Type Journal Article
  Year 2007 Publication Behaviour Research and Therapy Abbreviated Journal Behav Res Ther  
  Volume 45 Issue 5 Pages 901-914  
  Keywords *Asian Continental Ancestry Group; China; Cognition; Cognitive Therapy/*methods; Cross-Cultural Comparison; *Culture; Humans; Treatment Outcome  
  Abstract The purpose of the present paper is to explore the conceptual compatibility between cognitive behaviour therapy (CBT) and the common values of Chinese Culture. In order to address such a question, the distinctive processes attributed to CBT (e.g., teaching of skills, emphasis on homework, cognitive processes, present/future focus), as summarized in the meta-analysis by Blagys and Hilsenroth [(2002). Distinctive activities of cognitive-behavioral therapy: A review of the comparative psychotherapy process literature. Clinical Psychology Review, 22, 671-706], and the core values of Chinese Culture, determined through an integration of The Hofstede Project, [Hofstede, G.H. (1980). Culture's consequences: International differences in work related values. Beverly Hills: Sage]. The Chinese Value Survey [Chinese Culture Connection (1987). Chinese values and the search for culture-free dimensions of culture. Journal of Cross-Cultural Psychology, 18, 143-164]. The Schwartz Value Survey [Schwartz, S.H. (1994). Cultural dimensions of values: Towards an understanding of national differences. In Kim, U., Trandis, H.C., Katiticibasi, C., Choi, S.C., & Yoon, G. (eds.), Individualism and collectivism: Theory, method and application (pp. 85-119). Thousand Oaks, CA: Sage] were used. A strong degree of compatibility between the two was found and it is argued that rather than developing new indigenized therapies, with some structural changes to the processes of CBT, this therapy can be effective for Chinese clients. It is further proposed that Chinese clients may benefit from challenging their irrational cognitions that are bound up in their strict adherence to social norms. Future recommendations for increasing the compatibility of CBT to Chinese culture are discussed.

  Title The driving forces for nitrogen and phosphorus flows in the food chain of china, 1980 to 2010 Type Journal Article
  Year 2013 Publication Journal of Environmental Quality Abbreviated Journal J Environ Qual  
  Volume 42 Issue 4 Pages 962-971  
  Keywords Nitrogen; Phosphorus; China; Food--production, consumption; Nutrient Management  
  Abstract Nitrogen (N) and phosphorus (P) use and losses in China's food chain have accelerated in the past three decades, driven by population growth, rapid urbanization, dietary transition, and changing nutrient management practice. There has been little detailed quantitative analysis of the relative magnitude of these driving forces throughout this period. Therefore, we analyzed changes in N and P flows and key drivers behind changes in the food (production and consumption) chain at the national scale from 1980 to 2010. Food (N and P) consumption increased by about fivefold in urban settings over this period but has decreased in rural settings since the 1990s. For urban settings, the integrated driving forces for increased food consumption were population growth, which accounted for approximately 60%, and changing urban diets toward a greater emphasis on the consumption of animal products. Nutrient inputs and losses in crop and animal productions have continuously increased from 1980 to 2010, but the rates of decadal increase were greatly different. Increased total inputs and losses in crop production were primarily driven by increased crop production for food demand (68-96%) in the 1980s but were likely offset in the 2000s by improved nutrient management practices, as evidenced by decreased total inputs to and losses from cropland for harvesting per nutrient in crop. The contributions of animal production to total N and P losses to waters from the food chain increased by 34 and 60% from 1980 to 2010. These increases were caused mainly by decreased ratios of manure returned to cropland. Our study highlights a larger impact of changing nutrient management practice than population growth on elevated nutrient flows in China's food chain.
