American Hegemony in Packaged Software Trade and the 'Culture of Software'

United States-based companies continue to dominate the global market in packaged software. Although many have predicted this U.S. dominance will wane, particularly as a result of competitive threats from Japan, and more recently from low-wage, developing nations, erosion has yet to be significant. The United States benefits from nine factors that sustain its advantage in this industry: skilled labor, favorable capital conditions, sophisticated customers, close association with hardware vendors, a competitive marketplace, geographic concentrations, first-mover advantage, a strong intellectual property regime, and English as the software lingua franca. Industry-specific strengths and weaknesses vis-a-vis Europe, Japan, and other nations are also discussed. In addition to these nine better known U.S. competitive advantages, two culturally linked assertions are presented that have received scant attention vis-a-vis competitive analysis. First, the industrial evolution of software development is at an immature stage-still a cottage industry practiced by craftsmen in a cultural milieu of artisans-and thus does not track other global high-technology trends. Second, packaged software is part of the copyright industry (e.g., film and music) in which United States-based firms have a sustained advantage. While manufacturing capabilities are significant for technology industries, culturally related factors, such as creativity, are more important for copyright industries. The U.S. ''culture of software,'' which helps explain U.S. hegemony, is introduced and discussed. The three elements of this culture are the culture of individuals as manifested by the individualistic computer hacker; the entrepreneurial culture and its risk-taking ethos; and the software development culture with its embrace of ad hoc, innovation-driven development as opposed to routinized, production-driven development.     

韩国人对陈璘的回忆机制：神宗皇帝八赐品

壬辰倭乱期间（1592-1598）,陈璘受命率部进入朝鲜半岛抗倭,与朝鲜名将李舜臣紧密合作,取得平定倭寇的赫赫战功。陈璘回国后,在李舜臣军营里发现一些物品,即所谓＂八赐品＂,现被指定为国家级宝物。韩国人认为,八赐品是陈璘建议神宗皇帝而下赐给李舜臣的礼品。八赐品给李舜臣的生平带来光环,也激发了当今韩国人的自信。近几十年来,韩国文化界对李舜臣的追慕日益加深,对八赐品的关注度很高,神宗皇帝八赐品构成当今韩国人对陈璘的回忆机制。
