Shows equilibrium always exists (Rothschild-Stiglitz-Wilson model) when firms enforce policy exclusivity via strategic (profit-maximizing) communication of client purchases. Strategic communication induces two equilibrium types: partial communication of purchase information or non-communication which exhibits a lemon effect (low-risk purchase no insurance). Nonetheless, Jaynes' configuration (J...
INTRODUCTION More than 80% of schistosomiasis patients in China live in the lake and marshland regions. The purpose of our study is to assess the effect of a comprehensive strategy to control transmission of Schistosoma japonicum in marshland regions. METHODOLOGY/PRINCIPAL FINDINGS In a cluster randomized controlled trial, we implemented an integrated control strategy in twelve villages from ...
Schistosomiasis japonica has long been endemic in the People's Republic of China. In the 1950s, the number of the infected persons was estimated at 10 million; infected snail habitats were estimated at more than 14 billion square metres and infected cattle at 1.2 million. After schistosomiasis control measures were carried out, it was a great success. According to the survey of 1989, infected p...
The Iberian hare (Lepus granatensis Rosenhauert, 1856) is a widely distributed endemic species in the Iberian Peninsula. In order to improve our knowledge of its population dynamics, the relative abundance and population trends of the Iberian hare were studied in the autumns of 1995–2012 in a protected area (Doñana National Park) by spotlighting in two different habitats: marshland and ecotones.
BACKGROUND Oncomelania hupensis is the unique intermediate host of Schistosoma japonicum, which causes schistosomiasis endemic in the Far East, and especially in mainland China. O. hupensis largely determines the parasite's geographical range. How O. hupensis's genetic diversity is distributed geographically in mainland China has never been well examined with DNA sequence data. METHODOLOGY/PR...
Methane emissions associated with the conversion of marshland to cropland and climate change on the Sanjiang Plain of Northeast China from 1950 to 2100 T. Li, Y. Huang, W. Zhang, and Y. Q. Yu State Key Laboratory of Atmospheric Boundary Layer Physics and Atmospheric Chemistry, Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029, China The State Key Laboratory of Vegeta...
Methanogens, a key contributor in global carbon cycling, methane emission, and alternative energy production, generate methane gas via anaerobic digestion of organic matter. The methane emission potential depends upon methanogenic diversity and activity. Since they are anaerobes and difficult to isolate and culture, their diversity present in the landfill sites of Delhi and marshlands of Southe...
