ABSTRACT This article, rationale for the lifelong professional work of the author, shows how conceptual revolutions have changed the way we view our world. The author believes that another conceptual revolution is needed as we “learn how to live within the limits of the ecosphere that gave birth to us.” That means replacing the 10,000-year-old block-field agriculture system with perennial food and soil-building crops system. This change is needed to replace the energy-intensive planting, fertilizing, and harvesting of single annual crops by the application and use of expensive hydrocarbons that pollute the air, soil, and water. The 35th anniversary (November 2005) issue of Smithsonian magazine profiles Jackson as one of “35 Who Made Difference” in shaping our present and future world. This article is presented in PLQ because it lays out proactive alternative to an energy-intensive agriculture and modest, piecemeal environmentalism. The author's citations of scholars and ecological movements lead readers to numerous individuals and organizations working to create viable food-production pathway to achieve bright future for our world. 相似文献

Wes Jackson 《Public Library Quarterly》2013,32(2):167-173
This article is expanded from a commencement address delivered by author Wes Jackson to graduating seniors at Washington College, Chestertown, Maryland, May 20, 2007. It adds detail to his longstanding argument that the environmental majority is mendaciously optimistic in suggesting that new—and sometimes still uninvented—technology will solve the world's food and energy problems. Jackson lays out statistics on how fast the world is using up its energy sources, noting that biofuels such as agriculture‐based ethanol will provide insufficient energy to power U.S. cars and trucks even if we use all of the food in the world to produce motive power. Jackson's previous article, “Conceptual Revolutions: Who Needs Them? Why?” was published in Public Library Quarterly 24‐3 (2005). The two articles form an intertwined statement on world resource limitations and opportunities. These articles were selected for inclusion in PLQ for the fundamentally different view they offer library professionals on the biofuels‐and‐ecology debate, in the hopes of balancing competing points of view in library collections. 相似文献

Wes Jackson 《Public Library Quarterly》2013,32(1):60-63
In this article, author Wes Jackson reminds us that the professions have a special responsibility to their knowledge heritage-what he calls “a way of knowing” about our current society, its recent changes and those that will come in our lifetimes. He points out that talk radio and the even more bizarre guerilla war of manipulated-issue television are not the place to get at the imperative facts about our way of life. The centerpiece of Jackson's concern is world climate change. He calls on professionals to use their scientifically based “way of knowing” to decide and help carry out the action that must be taken if climate change is going to be reversed. The problem, quite simply, is to find a way to power the Planet Earth on one-fifth of the carbon-based fuels that we use today to sustain our lifestyles and our commerce. Jackson points out that this challenge is a huge one, and that to be effective in this cause, lots of “neutral” professionals are going to have to become proactive in helping find and implement climate solutions. 相似文献

The traditional design for the study of language variables is a controlled message design in which one kernel message is manipulated to produce message variations that represent the language variable contrasts. Thus message content is the same across treatment conditions and hence crossed with the treatment factors. Jackson and Jacobs (1983) criticized this design on three grounds. They argued that messages should be natural rather than contrived, that messages should be nested within treatment conditions rather than crossed with treatment factors, and that each study should use as many messages as possible. Their paper has been used by reviewers as the basis for rejecting studies done using the traditional design. This paper presents a detailed analysis of the arguments presented in Jackson and Jacobs (1983) as well as subsequent papers by Jackson (1984) and Jackson and Jacobs (1987). The arguments are shown to contain both methodological and substantive errors. When the arguments are corrected, it is shown that nested designs and multiple messages should be used only when absolutely necessary. It is the traditional controlled message, crossed design and not the naturalistic message, nested design which is robust; robust against not only incidental but fundamental confounding, robust against message by treatment by message interactions, and relatively robust against Type II error. Taken together with meta‐analysis, the traditional single message, crossed design can detect and identify message by treatment interactions. On the other hand, the multiple message design makes it impossible to identify such interactions. 相似文献

随着我国城市化和经济建设的快速发展,一座座高楼大厦鳞次栉比拔地而起,塑造了高密度的新城市景观。由于土地资源本身固有属性的限制,土地供需矛盾,尤其是高密度地区用地供需矛盾日益尖锐。图书馆建筑也出现低层向多层纵向发展的态势,其周边绿地表现出新的空间特征。在这种背景下如何做好绿地规划与建设,本文提出一些原则和方法,以期图书馆空间环境质量得到不断提高。 相似文献

经济全球化是当今世界经济发展的重要特征,随着经济全球化的发展,国家经济安全的地位日益重要。中国在经济全球化进程中经济发展的主要风险有:产业结构层次低,市场化程度低,在国际生产、贸易、投资领域处于劣势地位;农业基础薄弱,农村和农业安全面临世界农产晶生产销售大国的冲击;金融体系不完备,在面对国际金融巨头竞争、规避国际金融风险方面尚缺乏有效的机制和手段。为此,我国必须切实建立起完善的社会主义市场经济体制,优化产业结构;进一步加强农业在国民经济中的基础地位,提高农业产业的国际市场竞争能力;深化金融改革,完善金融体系,确保国家经济安全。 相似文献

ABSTRACT On June 3–5, 2008, international organizations and heads of state met in Rome to discuss the critical situation in global food supplies and prices during the World Food Crisis Summit. The intent of this column is to provide approaches to identifying the complex issues that impact public health, public safety, and nutrition on a global basis. The Web sites selected provide a background for the complex issues involved (energy, climate and environment, agriculture, and politics) and reveal controversial and competing agendas with many far-reaching implications. 相似文献

Agriculture is an important sector of the economy in India as it provides employment to a large number of people and is concerned with the food and nutritional security of a huge population. Indian agriculture is facing several challenges ranging from farmers' debt, climatic changes, technological up-gradation, development of communication infrastructures for more effective extension activities and most importantly, bridging the knowledge gaps existing within India. This article examines the hurdles the Indian agricultural sector face and the potential of ICTs to aid and enhance agricultural development. 相似文献
