Sloth, Silence, and Concentration: The Reader Between Letter and Spirit

In current-day criticisms of consumer culture as well as of the performativity culture of the work place, the originally religious concept of the vice of acedia or sloth is reinterpreted as a virtue. Art, especially poetry, is put to the fore in that connection. The image of the reader is addressed when the question of the relationship between poetics and religion is under discussion. The observation of the decline of reading has often been part of forms of cultural criticism and pessimism. Empirical research from the Netherlands over a few decades as to the free time spent in reading as compared to other leisure activities, is reviewed. The pattern emerges that not reading as such, but reading books is losing ground. The “Cultural Citizen” of present, as characterized by the Dutch Culture Council in 2007, is involved in so many diverging leisure activities, that the time and quiet needed for the time-honoured pastime of reading is lacking. The article then discusses the question whether there is a relationship between poetics and religion as to their imminent concentration and contemplation. An intrinsic relation between poetry and reading on the one hand and religion and transcendence on the other, is advocated by the famous British literary theorist George Steiner and by the Dutch essayist Jan Oegema. Steiner distinguishes five categories of solitude in his Grammars of Creation (2001). These categories are explored in order to test the validity of the idea that the seeking of solitude and concentration necessary for reading, eventually leads to spiritual and religious experience. This idea is rejected. In conclusion, reading is, after the fashion of the novelist Milan Kundera, tied to the experience, not of a transcendent unity, but rather of a polyphony of human voices.

Competition,Concentration and Diversity in European Television Markets

This study investigates how competition, concentration and public broadcasters influence diversity of programme supply in European television markets. It focuses on free, national generalist channels; studies programmes as provided throughout the day; and tests hypotheses with data on Finland, France, Germany, Greece, Italy, the Netherlands, Spain and the U.K. for the late 1980s and 1990s. It concludes that competition is moderate in most markets. Under these conditions, competition and concentration contribute to a diverse supply of programmes that mirrors audience demand, while public broadcasters increase diversity of supply above competitive market levels.

知识密集与农业经济的发展

技术进步对经济的作用越来越重要,其结构性变化越来越引起人们的注意。随着经济工业化发展,农业逐步成为经济中的一个很小的部门,它与整体经济的相互作用关系,以及与其他社会活动的联系,从内容到形式,都具有相当的附属性,受惠于社会的多方面进步,形成了与其他部门不尽相同的增长方式和技术进步趋势。在总的趋势上,知识密集也必然意味着农业地域专业化程度的提高和农场规模的增大。
