    The strong decays of charm-strange baryons up to N=2 shell are studied in a chiral quark model. The theoretical predictions for the well determined charm-strange baryons, Ξc∗(2645)\Xi_c^*(2645), Ξc(2790)\Xi_c(2790) and Ξc(2815)\Xi_c(2815), are in good agreement with the experimental data. This model is also extended to analyze the strong decays of the other newly observed charm-strange baryons Ξc(2930)\Xi_c(2930), Ξc(2980)\Xi_c(2980), Ξc(3055)\Xi_c(3055), Ξc(3080)\Xi_c(3080) and Ξc(3123)\Xi_c(3123). Our predictions are given as follows. (i) Ξc(2930)\Xi_c(2930) might be the first PP-wave excitation of Ξcâ€Č\Xi_c' with JP=1/2−J^P=1/2^-, favors the $|\Xi_c'\ ^2P_\lambda 1/2^->or or |\Xi_c'\ ^4P_\lambda 1/2^->state.(ii) state.

    The mass media is the window for reflecting the mass ideology. The article makes a thorough analysis on the marginalization of female discourse power and studies the potential sexual discrimination of this phenomenon, regarding females as the subjects and the objects of the mass media, and then further traces its deep reason upon which many constructive suggestions and improved measures have been proposed. The article aims at awakening the masses to establish the correct sexual ideology in harmony and pursue the equality of discourse power between females and males. Key words: mass media; female discourse power; marginalization; sexual discriminationRĂ©sumĂ©: Les mĂ©dias de masse est la fenĂȘtre pour reflĂ©ter l'idĂ©ologie de la masse. Cet article fait une analyse approfondie sur la marginalisation du pouvoir du discours fĂ©minin et Ă©tudie la discrimination sexuelle inhĂ©rente Ă  ce phĂ©nomĂšne tandis que les femmes sont les sujets et les objets des mĂ©dias de masse. Il explore en outre la raison profonde de ce phĂ©nomĂšne sur laquelle des suggestions constructives et des mesures amĂ©liorĂ©es ont Ă©tĂ© proposĂ©es. L'article vise Ă  l'Ă©veil des masses Ă  fin d'Ă©tablir une idĂ©ologie sexuelle correcte et harmonieuse et de poursuivre l'Ă©galitĂ© du pouvoir de discours entre les femmes et les hommes.Mots-ClĂ©s: mĂ©dias de masse; pouvoir du discours fĂ©minin; marginalisation; discrimination sexuell

    From Evolution of Dialect “Huoguo” to Harmonious Essence of Jing-chu Culture

    The purpose of this paper is to study the relationship of language and culture from a typical microscopic perspective of harmonious essence of Jingzhou culture in the evolution of dialect “huoguo” (or: “hodgepodge” ) from which we get the conclusion that language and culture are so highly influenced with each other that the former can not be existed without the latter. Key words: harmonious essence; Jing-chu culture; huoguo; evolution language and culture RĂ©sumĂ©: Le but de cet article est d'Ă©tudier la relation entre la langue et la culture Ă  partir d’une perspective microscopique typique de l’essence harmonieuse de la culture des royaumes Jing et Chu dans l'Ă©volution du dialecte "huoguo" (ou: «fatras») Ă  partir de laquelle nous avons conclu que la langue et la culture sont si fortement influencĂ©s l’une par l’autre que la premiĂšre ne peut pas exister toute seule sans la derniĂšre. Mots-ClĂ©s: essence harmonieuse; la culture des royaumes Jing et Chu; huoguo; Ă©volution de la langue et de la cultur
