苏轼(苏东坡)和王守仁(王阳明),这是两个在中华文化史上具有顶级影响力的名字。他们各自所处的时代相差400余年,不可同日而语;他们一个是北宋文学家、思想家、政治家,一个是明代哲学家、政治家、军事家;他们的生活道路、政治生涯、文化贡献、历史影响都很不相同。但苏轼和王守仁,有许多相似或相近之处,比如他们的社会背景、政治抱负、人生遭遇、思想倾向、文化情怀等等。比较苏轼和王守仁的相同与不同,对于认识、反思中国古代的政治生态和文化走向是有启示意义的。

至少从弗里德里希·基特勒(Friedric. Kittler)宣称光纤电缆是“媒介的终结”以来,电影和媒介研究领域就有了这样一种观点:随着所有的媒介变成数字化,媒介特异性的概念就逐渐变得越来越没有意义。与此同时,随着媒介学者将注意力转向诸如尘埃、城市和鲸鱼,很多人都质疑我们的领域是否具有一致性。我认为尽管表述方式有所变化,但数字融合使媒介特异性变得更为重要,而不是无足轻重。虽然我们的研究对象广泛,无法凝聚我们的学科,但将媒介特异性的使用作为一种历时性的、尺度灵活的、关系性的、视角化的运作却可以做到。

The problem of optimal plac.ment and sizing(OPS) of renewable distributed generation(RDG) is followed by numerous tec.nic.l, ec.nomic.l, geographic.l, and ec.logic.l c.nstraints. In this paper, it is investigated from two viewpoints, namely the simultaneous minimization of total energy loss of a distribution network and the maximization of profit for RDG owner. The stoc.astic.nature of RDG suc. as the wind turbine and photovoltaic.generation is ac.ounted using suitable probabilistic.models. To solve this problem, a hybrid metaheuristic.algorithm is proposed, whic. is a c.mbination of the phasor partic.e swarm optimization and the gravitational searc. algorithm. The proposed algorithm is tested on an IEEE69-bus system for several c.ses in two sc.narios. The results obtained by the hybrid algorithm shows that it provides high-quality solution for all c.ses c.nsidered and has better performanc.s for solving the OPS problem c.mpared to other metaheuristic.population-based tec.niques.
