China’s Challenging the “Ricardo Law” Circle： Is world development inevitably antagonistic or conflictive

World historical development, especially the development of modern and contemporary globalization, tends to be antagonistic, conflictive and non-harmonious. Its theoretical demonstration is “Ricardo Law” circle, namely the rule that social productivity development and historical progress are at the expense of certain social classes and strata. Western countries after the Second World War have hence changed partly in certain ideas, productivity and specific regulations. Will China be fettered by “Ricardo Law” circle in our transformational socialism and has to apply the antagonistic, conflictive and non-harmonious method to achieve the alienating “development”? This paper analyzes the harmony and conflict thoughts and policies of the western economics represented by “Ricardo Law” in order to probe into our socialist social and economic harmony theory. Key words: Ricardo Law, harmony and conflict thoughts of western economics, Harmonious Society Theory Résumé: Le développement historique du monde, notamment le développement de la globalisation moderne et contemporaine, tend à s’avérer antagoniste, conflictuel et non harmonieux. La démonstration théorique est le cercle de la « loi de Ricardo », à savoir la règle que le développement de la force productive sociale et le progrès social sont aux dépens de certaines classes et souches sociales. Après le Seconde guerre mondiale, les pays occidentaux ont changé en partie certaines idées et des régulations spécifiques. Est-ce que la Chine sera enchaînée par la loi de Ricardo dans notre socialisme transformationnel et aura à appliquer la méthode antagoniste, conflictuelle et non harmonieuse pour accomplir le développement aliéné ? Le présent article analyse les pensées et politiques d’harmonie et de conflit des pays occidentaux, représentées par la loi de Ricardo, dans le but d’explorer la théorie d’harmonie économique et sociale socialiste de notre pays. Mots-Clés: loi de Ricardo, pensées d’harmonie et de conflit des pays occidentaux, théorie de la société harmonieus

Discovery of six high-redshift quasars with the Lijiang 2.4m telescope and the Multiple Mirror Telescope

Quasars with redshifts greater than 4 are rare, and can be used to probe the structure and evolution of the early universe. Here we report the discovery of six new quasars with $i$-band magnitudes brighter than 19.5 and redshifts between 2.4 and 4.6 from the YFOSC spectroscopy of the Lijiang 2.4m telescope in February, 2012. These quasars are in the list of $z>3.6$ quasar candidates selected by using our proposed $J-K/i-Y$ criterion and the photometric redshift estimations from the SDSS optical and UKIDSS near-IR photometric data. Nine candidates were observed by YFOSC, and five among six new quasars were identified as $z>3.6$ quasars. One of the other three objects was identified as a star and the other two were unidentified due to the lower signal-to-noise ratio of their spectra. This is the first time that $z>4$ quasars have been discovered using a telescope in China. Thanks to the Chinese Telescope Access Program (TAP), the redshift of 4.6 for one of these quasars was confirmed by the Multiple Mirror Telescope (MMT) Red Channel spectroscopy. The continuum and emission line properties of these six quasars, as well as their central black hole masses and Eddington ratios, were obtained.Comment: 7 pages, 2 figures, published in Research in Astronomy and Astrophysics (RAA) as a lette

A Hybrid-Extragradient Scheme for System of Equilibrium Problems, Nonexpansive Mappings, and Monotone Mappings

We introduce a new iterative scheme based on both hybrid method and extragradient method for finding a common element of the solutions set of a system of equilibrium problems, the fixed points set of a nonexpansive mapping, and the solutions set of a variational inequality problems for a monotone and -Lipschitz continuous mapping in a Hilbert space. Some convergence results for the iterative sequences generated by these processes are obtained. The results in this paper extend and improve some known results in the literature.</p
